Description

Profile element for a frame construction and frame construction with such a profile element

The invention relates to a profile element for forming a frame construction, with a receiving groove for receiving at least one foreign element

having a receiving profile section, a arranged on the side facing away from the opening of the receiving groove side of the receiving profile section

Mounting profile section and a mounting profile section with the

Connecting profile section connecting connecting portion, wherein between the receiving profile section and the mounting profile section in the region of

Connecting portion is provided at least one mounting groove. Furthermore, the invention relates to a frame construction, preferably for a backdrop, a stage, a pedestal or a grandstand, comprising a plurality of interconnected

Profile elements. Profile elements have long been used to form frame structures. The profile elements provided for this purpose are generally elongate profiles which have a much longer extent in the longitudinal direction than in the two other spatial directions perpendicular to the longitudinal direction. Some or all profile elements of a frame construction may be similar or at least similar. A similar or similar structure of the profile elements is characterized by a substantially same cross section of the profile elements perpendicular to the longitudinal direction of the profile elements. To form a frame construction, the ends of the profile elements can be provided with mitres, for example, four profile elements arranged abutting against each other at their ends provided with mitres and connected there, for example welded, to be. The four profile elements can be arranged in such a way be that each two opposite profile elements are substantially parallel to each other and are substantially equal in length. In this way, a substantially rectangular frame construction seen in plan view can be formed.

Such frame structures are used for example as backdrops for stages, as described in DE 10 2012 012 043 AI. This profile elements are used, which have two outer receiving profile sections. The receiving profile sections each have a receiving groove with a

Receiving groove opening and two, the receiving groove opening laterally limiting

Aufnahmenutflanken. In this case, the receiving groove openings of a profile element to opposite sides. The grooves are for recording

Foreign elements provided. Such introduced into the receiving groove

Foreign elements serve, for example, the connection of decorative elements, such as provided with a design decoration. These can be regularly connected by stapling by means of brackets or by means of other connecting means with the foreign element and thus be tensioned on the frame construction. The one to one

Frame construction composite, and with decorative elements

provided profile elements can then form a stringed frame construction, which can be used, for example, as a backdrop for a set design.

The backdrops formed by frame structures may, if necessary, be provided on a stage, a pedestal or a grandstand. It is under

Circumstances may require that the frame structures be connected to the stage, pedestal or grandstand. This is sometimes quite expensive and time-consuming, which is disadvantageous insofar as there is often time pressure during the construction and dismantling of scenes, stages, podiums and grandstands.

Therefore, the present invention seeks to design the profile element and the frame structure of the aforementioned type in each case and to further develop that the assembly and disassembly of scenes can be further simplified.

This object is achieved in a profile element according to the preamble of claim 1, characterized in that the mounting profile section has at least one at least substantially closed cross-section exhibiting hollow chamber profile.

The aforementioned object is further achieved in a frame construction according to the preamble of claim 12, characterized in that at least one profile element according to one of claims 1 to 11 is formed.

By providing a hollow chamber profile of the mounting profile section is stiffened and thus increases the stability of the profile element. Of the

Montageprofilabschnitt with the hollow chamber is complementary to the

Receiving profile section provided with the receiving groove. This allows the profile element on the one hand on the receiving profile section of the connection

serve decorative elements and on the other hand by the stiffened

Mounting profile section also be provided for the formation of more stable frame structures, such as a stage, a pedestal or a grandstand. At the stage, the pedestal or the grandstand then a decorative element can be used directly, without the need for a separate backdrop.

For this purpose, the mounting profile section has at least one hollow chamber profile with an at least substantially closed cross section perpendicular to the longitudinal direction of the profile element. Under a substantially closed cross-section is to be understood that it does not matter that the profile element has a completely closed cross-section. Rather, slots, bores or the like may be provided in the hollow-chamber profile distributed over its extent in the longitudinal direction, so that the cross-section is closed only in sections. Thus, by substantially closed, it may be understood that the cross-section is at least one location or locations relative to the one or more locations Extension of the profile element in the longitudinal direction is completely closed.

In principle, it is conceivable, but less preferred from a constructional point of view, if the cross-section at one or more points is almost completely closed, but nowhere completely closed. Thus, it may only be important that the at least substantially closed cross-section of the

Hollow profile the mounting profile section and thus the profile element stiffened, which is why it is also preferred if the cross section of the hollow chamber profile is completely closed. The mounting profile section can also be several hollow chamber profiles, if necessary, in each case with an at least substantially closed

Cross section, exhibit.

The at least one hollow chamber profile serves to reinforce the

Mounting profile section, as this increases the rigidity of the mounting profile section. Thus, larger loads can be absorbed by the profile element, so that a load-bearing property of the profile element to the property to be able to absorb foreign elements via the receiving profile section,

come in addition. It is achieved a profile element with variable applications, which can be used both for connecting decorative elements for scenes and, if necessary, at the same time, for stronger frame structures for the construction of stages, podiums or grandstands.

Using the profile elements allows for a single frame construction

Various uses are ensured, so that sets

Providing frame structures no longer need to be tied separately to stages, podiums or stands. This reduces the time required for the construction of scenes and thus simplifies the assembly and disassembly of scenes for stages, podiums or grandstands.

In a first preferred embodiment of the profile element has the

Receiving profile section at least one hollow profile for stiffening the

Recording profile section on. The hollow chamber profile of the receiving profile section reinforces the receiving profile section, so that higher forces

can be included. It is achieved with respect to a load-bearing safer, more suitable for the construction of stages, podiums or grandstands profile element. The hollow chamber profile of the receiving profile section can a

Having closed cross-section, the cross-section must be at least substantially closed analogous to the above-described cross section of the hollow chamber profile of the mounting profile section only. Of the

Receiving profile section may also have a plurality of hollow chamber profiles, if necessary, each having an at least substantially closed cross-section.

It is further preferred if the hollow chamber profile of the receiving profile section is provided between the connecting portion and the receiving groove. This arrangement may mean based on the entire profile element that the

Montageprofilabschnitt merges with the hollow chamber profile of the mounting profile section first in the connecting portion, the connecting portion then merges into the hollow chamber profile of the receiving profile section and the receiving groove of the receiving profile section adjoins this leads to a

Stiffening of the receiving groove and thus to a stiffening of the

Receiving profile section and the entire profile element.

Additionally or alternatively, the receiving profile section and the

Mounting profile section an at least substantially common

Define profile element level. The common profile element level can extend through the entire profile element along its extension in the longitudinal direction. In addition, both the receiving profile section and the mounting profile section will preferably lie in the common profile element plane. Both

Sections can then be cut through the common profile element level. In this way, a stable and at the same time manageable

Profile element achieved. Preferably, the at least substantially common profile element level can be defined together with the connection portion, such as by the

Connecting portion also in the common profile element level or by the common profile element level substantially parallel to

Connecting section runs. As a result, the stability and manageability of the profile element can be further increased.

If the profile element is additionally formed at least substantially mirror-symmetrically to the profile element plane, a particularly simple handling of the profile element is possible. The profile element can then be optionally installed in two different orientations, since the cross-sectional halves on both sides of the profile element level is substantially identical or at least similar. Under essentially mirror-symmetrical to the profile element plane can be understood that deviations from the mirror symmetry are at least tolerable so far that a shoring of the profile element in the two

different orientations continue to provide readily, such as without additional structural elements, is possible.

According to a further preferred embodiment of the profile element of the receiving profile section and the mounting profile section at least in

Have substantially identical extensions perpendicular to the profile element level. Preferably, the receiving profile section and the mounting profile section may have an at least substantially identical width. In addition, the sections are, if necessary, aligned centrally to the profile element level, so that the profile elements can be easily installed optionally in two different orientations. This allows more simple profile elements in one

Frame construction can be combined with each other. A single profile element could then be installed in a frame construction in two different orientations, if necessary rotated by 180 ° about its longitudinal direction.

Corresponding frame structures and thus scenes, stages, podiums or grandstands can therefore be quickly and flexibly up, um- and dismantled. By substantially identical extensions or a substantially identical width may be meant that slight deviations from

identical lengths are insignificant in that respect that the profile elements can continue to be installed in a frame construction in the two different orientations, for example, rotated by 180 ° about its longitudinal direction.

Additionally or alternatively, the receiving profile section and the

Mounting profile section at least substantially identical extensions parallel to the profile element level. The receiving profile section and the mounting profile section can then, if necessary, have an at least substantially identical height. The handling of a composite of several profile elements frame construction is thus simplified. Because in such a frame construction, all profile elements can be installed in two different orientations. If necessary, some profile elements with the receiving profile section can be installed pointing to a frame construction side, while other profile elements are installed facing the mounting profile section pointing to the same frame construction side. Under the

Essentially identical extensions or a substantially identical width may be understood that minor deviations from identical lengths are irrelevant in that the profile elements can continue to be installed pointing in a single frame construction with their sections to the same frame construction side.

A particularly stable and simultaneously suitable for the connection of decorative elements profile element can be achieved by the ratio of

Extensions of the receiving groove and the hollow chamber profile of

Receiving profile section parallel to the profile element plane to each other between 0.3 and 2, preferably between 0.5 and 1.5, in particular between 0.75 and 1, is. Under the extension of the receiving groove parallel to the profile element level is to understand the depth of the receiving groove. This may preferably be the extension of the

Receiving groove flanks or the maximum distance between receiving groove opening and record reason. With regard to the hollow chamber, the extension between the receiving groove and the connecting portion of the profile element is preferably meant. A greater depth of the receiving groove causes, on the one hand, that larger

Foreign elements received in the receiving groove and thus decorative elements can be connected to the profile element safer. A greater height of the hollow chamber profile of the receiving profile section has a greater stability of the receiving profile section and thus of the profile element result. With the

described values, a good compromise for a stable profile element can be found at the same time as possible secure binding of decorative elements.

In a particularly preferred embodiment of the profile element, the receiving profile section on at least one side of the receiving groove a

Contact surface. The contact surface may be provided on the outside of a receiving groove flank and thus on an outer side of the profile element. If necessary, the contact surface extends substantially over the entire longitudinal direction of the profile element. Preferably, the contact surface is provided for contact with a similar profile element, so that the side of a profile element with the

Contact surface another, similar profile element can be brought into contact. Under a similar profile element is a profile element to understand, which has identical or at least similar outer dimensions in cross-section perpendicular to the longitudinal direction. It should be understood by at least similar external dimensions that it does not depend on minor deviations relative to the concrete designed cross-section of the profile element, such as holes, depressions, chamfers or grooves. So it can

be sufficient if the outer contours of the cross sections of the similar profile elements are substantially identical, to be brought along along their longitudinal direction adjacent to each other and aligned. Thus, then several formed from similar profile elements Frame structures are aligned and brought into contact with each other accordingly. The receiving profile section preferably has a corresponding contact surface on both sides of the receiving groove. It is preferred if the contact surface for contact with the

Receiving profile section of a similar profile element is formed. In this way, two profile elements can be easily aligned with each other and connected to each other, with two grooves can be positioned side by side. Alternatively, the abutment surface can be designed to bear against the mounting profile section of the similar profile element, so that the profile elements can simply be aligned with one another such that in each case a receiving groove and a mounting profile section are arranged adjacent to one another. It is preferred if the contact surface is designed to bear against both the receiving profile section and the mounting profile section of a similar profile element. Then, the two provided for investment profile elements in different

Be aligned with each other and brought into contact with each other, so that either two grooves or a receiving groove and a

Mounting profile section adjacent to each other are arranged. It can thus be achieved a diverse and flexible design of frame structures of several profile elements, in which, depending on the desired application, the built-in frame structures profile elements can be optionally arranged in one of two different orientations. The orientations can preferably be changed by turning the profile elements by about 180 ° perpendicular to the extension of the profile elements in the longitudinal direction.

Additionally or alternatively, the mounting profile section on at least one side of the profile element has a contact surface, preferably for engagement with a similar profile element. It is again preferred if the contact surface is designed to rest on the receiving profile section and / or the mounting profile section of the similar profile element. Likewise, the mounting profile section on both sides of the profile element having a contact surface described. In order to go before with respect to the contact surface of the receiving profile section

associated advantages. Preferably, the contact surface of the

Mounting profile section substantially parallel to the profile element level, in particular substantially parallel to the connecting portion, and particularly preferably substantially parallel to the by the contact surface of

Formed formed receiving section portion plane.

In addition, if in each case at least one contact surfaces of the

Receiving profile section and the mounting profile section are arranged in an at least substantially common plane, the profile element can be brought simultaneously on the plant surfaces on the one hand of the receiving profile section and on the other hand of the mounting profile section with other structural parts, such as other similar profile elements in abutment. The alignment of several profile elements, for example in a frame construction can therefore be done quickly, easily and depending on the requirements.

A simple and quick way to fix foreign elements in the receiving groove of the receiving profile section consists, by at least one barb element for positive fixing of the at least one in the receiving groove

Foreign element are provided in the receiving groove. The foreign element can then be simply pressed into the receiving groove and thus fixed without the

Foreign element is at risk of being pulled out again in the direction of the receiving slot opening. The assembly of the foreign element may be perpendicular and / or longitudinal to the receiving groove, that is, along the longitudinal direction of the profile element done. Extraction of the foreign element is prevented by the at least one barb element by the barb element engages in the foreign element. However, a foreign element can nevertheless be removed as required, for example, by the foreign element being pressed out of it along the receiving groove. Preferably, a plurality of barb elements in the receiving groove, preferably on each groove flank, be provided so that a safer bonding of foreign elements is made possible. It is not however, preferred if the one or more

Barb elements are provided over the entire extension along the longitudinal direction of the profile element. In order to ensure a quick and easy way of connecting decorative elements to a profile element, additionally or alternatively, the at least one foreign element is provided in the receiving groove and fixed a decorative means by at least one fastening means to the at least one foreign element. It is preferred that the connection of the decoration means of conventional connecting means, preferably by at least one clip, at least one nail and / or at least one screw, so that a quick, easy-to-handle and reversible connection possibility of decorative means to the foreign element and thus to the Profile element is achieved. Furthermore, a plurality of foreign elements in the receiving groove, approximately distributed over the receiving groove along the extension of the profile element in the longitudinal direction, may be provided, so that the foreign elements can be used sparingly only to the intended purpose to be bound with decorative elements bodies.

If the at least one foreign element is additionally formed from wood and / or plastic and / or the decorating means is a fabric or a plastic film, the decoration means can easily be attached to the at least one

Foreign element tethered and maintained manufacturing techniques are maintained. With the materials mentioned decorating means can be easily connected by tacking, nailing and / or screws with foreign elements, so that a quick assembly and disassembly of decorative materials and thus of scenes is guaranteed.

The profile element may additionally or alternatively be made of plastic or metal for cost reasons. Profile elements made of plastic can preferably be produced by extrusion, while profile elements made of metal can be produced simply by extrusion. Because of the good processability and the low weight comes as metal in particular aluminum or an aluminum alloy in question.

According to a first preferred embodiment of the frame construction, the profile elements are at least substantially similar. An im

Essentially similar construction of the profile elements is characterized by a same or at least similar cross-section perpendicular to the longitudinal direction of the profile elements. In this way, the profile elements of their variable

Possible applications are flexibly used in the frame construction, so that a less complex and less time-consuming assembly and disassembly of scenes, stages, pedestals or grandstands is achieved. For the purpose of a simple and flexible connection of the similar profile elements to each other, the profile elements may additionally or alternatively have at least substantially identical outer dimensions. By at least substantially identical is meant that only the outer contour with respect to the cross section perpendicular to the longitudinal direction of the profile elements is substantially identical. In particular, minor deviations with respect to the concretely configured cross-section, such as different holes, deviating indentations, bevels or grooves are irrelevant in the profile elements to be joined together.

In a particularly preferred embodiment of the frame construction, a sliding block is partially provided in each case a mounting groove of two interconnected profile elements. In this case, the sliding block can be provided to the same part in each case a mounting groove of the two profile elements. The mounting groove provided between the receiving profile section and the mounting profile section of a profile element is characterized in that the mounting groove opening is formed perpendicular to the profile element plane. The connecting portion of the profile element can represent the mounting groove bottom of the mounting groove. The Montagenutflanken can through the two to the connecting section

adjacent sections, namely the receiving profile section and the

Mounting profile section, be formed. In this embodiment of the Frame construction, a sliding block at least partially come into contact both with the mounting groove of the one and with the mounting groove of the other profile element. In this way, a good power transmission between the two profile elements can be ensured via the nut. It is preferred if the two profile elements, preferably on their outer sides, in particular over their contact surfaces, are arranged adjacent to each other. As a result, a more favorable power transmission is ensured, since the power transmission is made possible both via the sliding block and over the abutting areas of the profile element. A more stable frame construction can be achieved.

In particular, the sliding block of the positive connection of the

Profile elements, so that an easy-to-handle and reversible connection of the two profile elements can be gewährleitstet.

If the sliding block is additionally connected non-positively with the profile elements, a secure connection of the two profile elements with each other via the

Nutenstein be achieved. In this case, the sliding block may preferably be screwed in order to ensure an easily manageable, fast and reversible connection of the two profile elements. The nut may for this purpose have a bore, in particular a through hole, wherein in this bore a threaded insert may be provided for receiving connecting means. The sliding block may preferably be formed substantially from plastic, whereby a lighter frame construction can be achieved.

The invention will be explained in more detail with reference to a drawing illustrating only embodiments. In the drawing show

Profile elements according to the invention in a plan view, a profile element from FIG. 1 in a sectional view, Fig. 3, the frame structure of Fig. 1 with an adjacent

Frame construction in a sectional view and

4 shows a second frame construction according to the invention comprising two profile elements according to the invention in a sectional view.

In Fig. 1, a frame structure 1 is shown in a plan view. Furthermore, dashed frame constructions are shown. The

Frame constructions are all interconnected. The

Frame structures can be part of a backdrop or a stage, a pedestal or a grandstand, each optionally comprising a backdrop. The frame structures have a plurality of profile elements 2, 2A, 2B, namely for a circumferentially arranged and provided at the ends of their longitudinal direction with mitres profile elements 2, 2B. In this case, the profile elements 2 are arranged abutting against each other at the mitres and there, for example by means of welding, connected to each other, so that a rectangular frame of the frame structure 1 is formed. On the other hand, the frame structure 1 profile elements without mitres in the form of intermediate bar profile elements 2A. These

Intermediate bar profiles 2A can on the one hand serve to reinforce the frame structure 1 or on the other hand can provide additional desired functionality, such as allowing decorative elements such as decoration means to be tied to the frame structure 1 for a backdrop. The

Interlock bar profile elements 2A may be the same or with respect to the dimensions different from the other circumferentially arranged profile elements 2, 2B may be formed. If necessary, an intermediate bar profile element 2A can also be formed by two parallel and possibly interconnected profile elements 2, 2A, 2B.

The shown frame construction 1 can be used both for binding decorative elements in the form of decorative means to the frame construction 1,

For example, for a backdrop, as well as to build a stage, a pedestal or a tribune be used. On a representation of the decorative elements and, for example, floor panels for stages, podiums or grandstands was omitted for clarity in Fig. 1. For the provision of said different functionalities, the profile elements 2 have the cross-section shown in FIG.

2, the profile element 2 of FIG. 1 in the sectional view II-II is also shown, the intermediate bar profile element 2A and the further profile element 2B of FIG. 1 may have the cross-section shown in Fig. 2. The profile element 2 can be an extruded profile made of metal, for example aluminum, or else a profiled element 2 made of plastic by extrusion. The profiled element 2 has a receiving profile section 3 arranged at the top in the representation according to FIG. 2, and subsequently a connecting section 4 and subsequently a mounting profile section 5. Of the

Connecting section 4 thus connects the receiving profile section 3 with the mounting profile section 5.

The receiving profile section 3 has a receiving groove 6 which is suitable for receiving a foreign element, not shown. The receiving groove 6 is open to the mounting profile section 5 side facing away and is on the other

Sides of a receiving groove bottom 7 and two perpendicular to the receiving groove bottom 7 extending receiving groove flanks 8 enclosed or limited.

The profile element 2 can be assigned to two different outer sides, on the one hand, the recording profile section 3 associated and the

Connecting portion 4 facing away receiving profile section outside 9 and, on the other hand, the mounting profile section 5 associated with and

Connecting portion 4 facing away from the mounting profile section outside 10. For positive fixing of a foreign element, not shown in the receiving groove 6 are a plurality of barb elements 11 in the receiving groove. 6 intended. These barb elements 11 are on the insides of the

Receiving groove flanks 8 arranged and extend from these in the

Receiving groove 6 into it. If a foreign element is received in the receiving groove 6, the barb elements 11 can engage in the foreign element and thereby prevent unwanted withdrawal of the foreign element from the receiving groove 6.

For stiffening the receiving profile section 3, a hollow chamber profile 12 is also provided in the receiving profile section 3. The hollow chamber profile 12 of

Receiving profile section 3 is provided between the connecting portion 4 and the receiving groove 6. Furthermore, the hollow chamber profile 12 of the

Receiving profile section 3 has a substantially rectangular, closed cross section, wherein the receiving profile section 3 facing side of the hollow chamber profile is limited by the receiving groove bottom 7. Both the hollow chamber profile 12 of the receiving profile section 3 and the

Barb elements 11 in the receiving groove 6 are merely preferred and not required.

The profile element 2 forms a profile element plane P, wherein the

Profile element level P along the receiving profile section 3, the

Connecting portion 4 and the mounting profile section 5 extends. Of the

Receiving profile section 3 and the mounting profile section 5 thus define together with the connecting portion 4, the profile element level P. Die

Profile element plane P is perpendicular to the opening of the receiving groove 6 and parallel to the connecting section. 4

The profile element 2 is formed mirror-symmetrically to the profile element plane P. As a result, the cross section is perpendicular to the longitudinal direction of the profile element 2 seen from both sides identical. In addition, the receiving profile section 3 and the mounting profile section 5 have identical extensions perpendicular to

Profile element level P on, as well as identical extensions parallel to Profile element level P. This means that in Fig. 2 horizontally extending widths of the receiving profile section 3 and the mounting profile section 5, as well as the vertically extending heights of the receiving profile section 3 and the

Mounting profile section 5 are the same size. An approximate symmetry would be sufficient if needed.

The on the opening of the receiving groove 6 facing away from the

Mounting profile section 3 arranged mounting profile section 5 also has a hollow chamber profile 13. The hollow chamber profile 13 of the mounting profile section 5 has a closed cross section. The opening of the receiving groove 6 of the receiving profile section 3 facing away from the outside of the hollow chamber profile 13 also forms the mounting profile section outside 10 at the same time. Of the

Mounting profile section 5 is shown in the illustrated and so far preferred

Profile element 2 formed by the hollow chamber profile 13, without that as the receiving profile section 3 a receiving groove would be provided. The outside of the hollow chamber profile 13 of the mounting portion 5 thus provides a supporting surface for connecting other elements, for example of floor panels, when the

Mounting profile section 5 has in a frame construction upwards, ready. The connecting portion 4 of the profile element is designed in the form of a web 14, wherein the web 14 extends from the hollow chamber profile 12 of the receiving profile section 3 to the mounting profile section 5. The web 14 thereby closes centrally on the side facing away from the receiving groove 6 of the hollow chamber profile 12 of the

Receiving profile section 3 and is in the middle in the mounting profile section 5 on. Further, halfway along the connecting portion 4 between

Receiving profile section 3 and mounting profile section 5 two opposite Zentrierungsnuten 15 provided in the web 14. By means of these Zentrierungsnuten 15 further mounting elements, for example, for connecting a plurality

Profile elements 2 with each other, are positioned. The extension of the connecting portion 4 or web 15 of the profile element 2 perpendicular to the profile element plane P is less long than the extensions of the receiving profile section 3 and the mounting profile section 5 perpendicular to the profile element plane P. That means, the connecting section 4 is based on the cross section of the profile element 2 less wide as the receiving profile section 3 and the mounting profile section 5 is formed. This way is between the

Receiving profile section 3 and the mounting profile section 5 in the region of the connecting portion 4 on both sides of the web 15 each have a mounting groove 16 is formed. In this case, the web 15 itself each the Montagenutgründe the

Mounting grooves 16 while the Aufnahmeprofilabschnitt- or

Montageprofilabschnittaußenseiten 9, 10 opposite sides of the Aufnahmeprofilbzw. Mounting profile sections 3, 5 represent the Montagagenutflanks 17 of the mounting grooves 16. Both the receiving profile section 3 and the mounting profile section 5 have on both sides of the profile element 2, in the case of the receiving profile section 3 on the sides of the receiving groove 6 and on the outer sides of the receiving groove flanks 8, contact surfaces 18, 19. The contact surfaces 18 of the receiving profile section 3 and the contact surfaces 19 of the mounting profile section 5 are arranged on each side of the profile element 2 in a common plane A. This common plane A runs at least substantially parallel to the profile element plane P and, for the sake of clarity, is shown in FIG. 2 only on the left side. The contact surfaces 18, 19 serve to bear against a similar profile element 2, in particular to the receiving profile section 3 and / or the

Assembly profile section 5 of a similar profile element 2. Similarly means in this context that the cross sections of the profile elements 2 are similar or even identical to each other with respect to their outer dimensions. In this way, in one composed of several profile elements 2

Frame structure 1, as for example in Fig. 1, a plurality of profile elements 2 via the contact surfaces 18, 19 aligned with each other and then connected to each other. In the profile element shown in FIG. 2 and so far preferred, the opening width of the receiving groove 6 is between 10 mm and 60 mm, preferably between 20 mm and 30 mm, and the opening widths of the mounting grooves 16 between 20 mm and 80 mm, preferably between 30 mm and 50 mm. The

Extentions of the receiving profile section 3 and the mounting profile section 5 perpendicular to the profile element plane P amount to between 10 mm and 80 mm, preferably between 20 mm and 40 mm, while the extension of

Connecting portion 4 perpendicular to the profile element plane P between 2 mm and 15 mm, preferably between 4 mm and 6 mm. The depth of the receiving groove 6, so the extension of the receiving groove 6 parallel to the profile element plane P is between 5 mm and 60 mm, preferably between 10 mm and 30 mm. The

Extensions of the receiving profile section 3 and the mounting profile section 5 parallel to the profile element plane P are between 20 mm and 120 mm,

preferably between 40 mm and 60 mm. The entire height of the profile element 2, ie the extension of the profile element 2 parallel to the profile element plane P, is between 60 mm and 300 mm, preferably between 110 mm and 170 mm.

In Fig. 3, two adjacent frame structures according to section III-III of Fig. 1 are shown. In this case, the profiled elements 2 shown on the left lie on its right abutment surfaces 18, 19 on the left contact surfaces 18, 19 of the profile element 2B shown on the right. The profile elements 2B in this case has the same cross-section as the profile elements 2 already described in FIG. 2, for which reason the same reference numerals are provided for the same functional elements. The orientation of the two profile elements 2, 2B is such that the profiled element 2 shown on the left faces the mounting profile section 5 upwards of an upper side of the frame structures, while the profiled element 2B shown on the right with the

Receiving profile section 3 up the same top of

Facing frame structures. The two profile elements 2, 2B abut with the contact surfaces 18, 19 of their

Receiving profile sections 3 and mounting profile sections 5 to each other, so that the two facing each other with their openings mounting grooves 16 of

Profile elements 2, 2B form an at least substantially closed cavity. In the cavity, a sliding block 20 is arranged, which serves the positive and non-positive connection of the profile elements 2, 2B. For this purpose, a through hole 21 is provided in the sliding block, in which a threaded insert 22 is inserted. The sliding block 20 is preferably formed substantially of plastic, while the threaded insert 22 may be a conventional sleeve made of metal with an internal thread.

In the form of webs 14 connecting portions 4 of the profile elements 2, 2B is provided at the same height as the slot nut 20 inserted into the cavity in each case a bore 23. The holes 23 of the connecting portions 4 are thus aligned with the through hole 21 of the sliding block 20 and the

Threaded insert 22. In the bores 23 of the profile elements 2, 2B and in the threaded insert 22 each engage from opposite sides two

Mounting means 24 a. Further, a washer 25 each of the

Cavity opposite sides of the connecting portions 4 between the

Mounting means 24 and the connecting portions 4 are provided. As a result, a better power transmission between mounting means 24 and profile elements 2, 2B is ensured.

The mounting means 24 may be conventional screws or as in the in Fig. 3

illustrated and so far preferred embodiment screws with a designed as a hand knob 26 turret be. This simplifies and speeds up handling during assembly and disassembly of frame structures. In this case, the hand knob 26 of the mounting means 24 protrude from the mounting grooves 16 of the interconnected profile elements 2, 2B, so that on the one hand a simple hand-to-handle access to the mounting means 24 is made possible.

On the other hand, the mounting means 24 via their hand knob 26 together with the mounting grooves 16 undercuts 27, in which further not

can intervene shown construction means. The mounting means 24 are screwed from opposite sides into the threaded insert 22 in the sliding block 20 and thus ensure a non-positive and reversible connection of the two profile elements 2, 2B with each other. If necessary, the mounting means 24 can be easily unscrewed from the threaded insert 22 and then the nut 20 are removed from the cavity between the connecting portions, so that the connection of the two profile elements 2, 2B is released again. In the manner described the connection of the two adjacent

arranged profile elements 2, 2B can thus also two adjacent

Frame structures, as shown several times in Fig. 1, are interconnected. Furthermore, two interconnected in the manner described profile elements 2, 2B can also be used as a wider than the intermediate bar profile 2A shown in FIG. 1 in a frame structure 1.

Furthermore, in the two receiving grooves 6 of FIG. 3 shown

Profile elements 2, 2B each foreign elements 28 added. The foreign elements 28 are fixed via the barb elements 11 in the receiving grooves 6, so that an undesired pulling out of the receiving grooves 6 can be avoided. If the foreign elements 28 are nevertheless to be removed from a receiving groove 6, then it is possible for the foreign element along the receiving groove 6, so the longitudinal direction of the profile elements 2, 2B along, push out of the receiving groove 6 or

-pull. On the right in Fig. 3 shown foreign element 28 of the profile element 2B, the receiving profile section 3 faces the top of the frame structures, a decoration means 29 is also connected. This is connected by means of a clamp 30 with the foreign element 28. Alternatively, a fixing by means of other fasteners nails and / or screws would be possible. The

Foreign elements 28 are preferably made of wood and / or plastic, while the decorative means 29 may be a fabric or a plastic film. On the

Decorating means 29 may be of any design to provide a backdrop be upset. The decorating means 29 is shown in the in Fig. 3

Embodiment braced upwards from the top of the frame structures. Also, on top of the frame structures are each on the

Mounting profile section 5 of the profile element 2 shown on the left and on the

Receiving profile section 3 with inserted into the receiving groove 6 foreign element 28 of the profile element shown on the right 2B 2B 31 placed. These plates 31 may be, for example, floorboards for a stage, a pedestal or a grandstand. As such, the plates 31 on the profile elements 2, 2B and thus on the

The load, which is transmitted via the plates 31 on the mounting profile section 5 and on the receiving profile section 3, on the one hand on the hollow chamber section 13 of the

Mounting profile section 5 and on the other hand via the hollow chamber profile 12 of the receiving profile section 3 collected. There are thus provided frame structures that can fulfill various functionalities, namely on the one hand enabling the connection of decorative elements and on the other hand the inclusion of loads, for the backdrop, stage, pedestal or grandstand by the flexibly deployable profile elements 2, 2B.

FIG. 4 shows a further frame construction 1A in a sectional view. In this case, a transverse profile element 2C and two longitudinal, cut profile elements 2D are shown. All illustrated profile elements 2C, 2D may have the cross section of the profile element 2 shown in FIG. 2, which is why the same reference numerals are provided for the same functional elements.

In contrast to the profile elements 2, 2B of the adjacent frame structures according to FIG. 3, the two profile elements 2D are similarly aligned with regard to their cross-section with regard to the arrangement in the frame construction 1A. This means that the receiving profile sections 3 of the profile elements 2D are the in Fig. 4th Right side shown facing the frame structure 1A, while the mounting profile sections 5 of the profile elements 2D of the left side of the frame structure 1A are facing. In the receiving grooves 6 of the profile elements 2D, a foreign element 28 is provided in each case, which over existing in the grooves 6

Barb elements 11 is fixed. To the foreign elements 28 is in each case by means of a bracket 30, a decoration means 29 connected, which around the

Frame construction 1A is stretched. This is a covered

Achieved frame structure 1A, which is on the left side by the, if necessary, provided with a design, decorative means 29 is covered. The formation of the foreign elements 28, the decoration means 29 and the connection of the decorative means 29 can be done on the previously described in the course of the frame structures of FIG. 3 ways.
