Description

FIELD OF THE INVENTION

The present invention relates to a node for fixing external elements, and in particular, to a node for laying siding of any material.

State of the art

The present invention relates to the field of fixing external elements to flat surfaces. Exterior flat roofs or facades are usually made of boards, for example, wooden strips mounted on a frame, which is formed, in particular, by panels pre-fixed to the floor or wall.

Today, wooden siding systems are known - the so-called tongue-and-groove systems, without open joints between siding strips. In the context of this type of system, a method is proposed that includes fastening the panels to a waterproof seal (usually a rubber-like mesh) on which siding boards are fixed by driving nails into the tongues provided for this purpose. The tongue of one board is connected into the lock with the groove of the board adjacent to it, specially profiled for this purpose. Since siding is not adequately ventilated, rot usually begins to form, destroying the siding support structure.

Other systems are characterized by inconspicuous mounts and open joints and have similar disadvantages. Open joints between siding boards provide improved siding ventilation. Nevertheless, the fastenings are made due to profiled grooves along the edges of the boards, which leads to accumulations of rainwater and contributes to the decay and spread of algae and insects on the structure. In addition, the tree can warp, because, due to the capillary effect, the final board is in contact with the siding, which is saturated with moisture penetrating into the tree. This leads to an increase in air humidity on the lower side of the finishing board compared to air humidity on the upper side, as a result of which the wooden surface strips bend and look unaesthetically.

The purpose of the present invention is to eliminate at least part of the negative aspects present in the prior art.

The implementation of the invention

The present invention will now be described by way of a preferred embodiment thereof and with reference to the accompanying drawings. Similar reference numbers in the drawings correspond to similar concepts in various embodiments of the present invention. For example, the mounting assembly of the present invention is indicated by 001, 101, 201.

In accordance with FIG. 1 and 2, the assembly 001 of the present invention includes at least one fastening rail element 020 having a C-shaped profile 024. It is preferable that the bottom side 021 of the rail is in contact with the support 002. Preferably, the rail 020 is attached to the support by means of threaded fasteners. Support 002 corresponds, for example, to a wall that is covered with siding. In a typical case, the rail element 020 is oriented vertically on the support. As can be seen from FIG. 2, the C-shaped profile has a recess that is oriented in the direction of the upper side of the rail 022 and defines a width of 025 profiles and a height of 026 profiles.

The assembly 001 also includes at least one mounting part 030. The mounting part 030 has a rectangular shape and serves to interconnect this at least one rail, which is attached to the support 002, and a fixed element. Part 030 comprises a base tile 031 having a thickness of 033 and a width of 034. It is preferable that the thickness of 033 substantially matches the height of the rail profile 020 of 020. It is also preferable that the width of 033 substantially matches the width of the rail profile 025 025. This allows progressive movement mounting part 030 in the rail profile 020. In fact, no separate mechanical connection means such as a screw or nail are required to secure the mounting part to the rail. This provides a quick erection of a frame that can hold fastened elements, for example, siding strips of wood, metal or composite material.

Preferably, node 001 is used to secure the siding to a vertical wall. Other forms of application of the assembly will be apparent to those skilled in the art, for example, laying parquet strips or ceiling strips on a horizontal support. Preferably, this at least one fastening member extends in a direction perpendicular to the direction in which this at least one rail extends. In a typical case, the siding strip is supported by a series of rails, at least one mounting part is mounted on each of them.

On the upper surface 039 of the mounting portion, there is at least one mounting means 040. The fastener means 040 is configured to accommodate a fastened member, such as a siding strip. Preferably, the fastening means 040 can be connected to the lock with a structure joining with it on the lower side of the element to be fixed, this lower side facing the mounting part and not visible after installation.

The fastening means is preferably configured so that the fastening element connected to the lock with the indicated fastening means 040 abuts against the surface 028 of the C-shaped profile of rail 020, this surface being formed by the protruding part of the rail, as shown in FIG. 2.

In order to optimize the method of fixing and fixing the mounting part on the rail, it is preferable to provide at least one gear surface 027 extending on the upper side 022 of the rail 020.

In this case, the mounting part 030 contains at least one structure with at least one joined tooth or groove 043 on its lower side 032. This structure with at least one tooth 043 can engage with this, at least one gear surface 027 of the rail 020, providing translational movement of the mounting part 030 along the rail 300 with a certain step. This allows the mounting part to be positioned on the rail in a precise and reproducible manner.

In FIG. 3a shows the structure of FIG. 2, while a fixed element 110, such as a siding strip, is also shown. The lower side 111 of the fixed element at least partially abuts against the upper surface 128 of the C-shaped rail profile 120. With this configuration, a ventilated space 105 is formed between the upper surface 139 of the mounting part and the lower surface 111 of the fixed element. Ventilated space 105 gives confidence the fact that the device is sufficiently aerated, which increases its service life.

The fixed element 110 is firmly fixed because it is firmly pressed against the rail 120. The mounting part fastening means 140 tightly presses the fixed element to the rail surface 128.

In accordance with FIG. 3b and 3c, it is preferred that the mounting part fastening means 140 comprise at least one protruding foot 141 that is oriented perpendicular to the base tile 131. According to a preferred embodiment of the present invention, a pair of legs or a series of pairs of legs 141 are disposed on the surface 131. This fastening means allows to hold the fixed element 110. The length of this at least one protruding leg 141 is such that the leg is connected to the lock with a recess 112 located on the lower side of the fixed element, at the same time it presses against the rail member 110 as shown in FIG. 3d and FIG. 3e. As can be seen from FIG. 3d, it is particularly preferable to configure the foot 141 so that in its length it protrudes above the surface 128 of the rail 120 by a length p when the mounting part is mounted on the rail. The length p is approximately equal to the depth of the recess 112. This configuration allows you to firmly fix the element on the rail. Indeed, the mounting part is capable of tightly pressing the lower side 111 of the element 110 to the surface 128 of the rail 120. Ideally, the length p should be less than a millimeter less than the depth of the recess.

Preferably, each paw 141 is provided with a spike 142 extending perpendicular to the paw on one of its sides. Preferably, the spike 142 is designed to interact with a groove 113 corresponding to it along the profile, located in the wall of the recess or longitudinal recess 112 of the fixed element 110.

Preferably, the spikes 142 of all paws 141 are oriented on the same side of their respective paws. This preferred configuration makes it easy to secure the siding strip 110 to the corresponding mounting portion 130. This is shown in FIG. 3b and 3d, in sections AA and BB, respectively. First, the securing strip 110 is positioned on the mounting portion 130 so that the legs 141 and the spikes 142 fit into the corresponding at least one recess 112. Then, the strip 110 is moved so that the spikes 142 enter the corresponding grooves 113, as shown in FIG. . 3c and 3e. In the case of a siding strip fixed on a vertical support, the corresponding movement is performed downward, which allows you to firmly fix the siding element on the mounting part.

Preferably, each recess 112 of the fastened element has an inlet section that is slightly wider than the inlet section of the legs provided with spikes, so that these legs can more easily enter the corresponding recesses.

In FIG. 4 shows a preferred mounting part. Preferably, the mounting portion 230 used to interconnect the support rail 220 and the fastening member 210 includes at least one stop 235 that extends from the upper side 239 of the base tile 231 and is located on the edge of the tile on the other side of the spikes 242. The position of this at least one stop 235 is selected so that when the strip 210 is moved to fit the grooves and studs together, the strip comes in contact with the stop. Preferably, this emphasis is located on the edge of the mounting portion 230, since in this case, the emphasis allows during the installation of the siding to indicate the size of the distance relative to the adjacent strip 210 ′ siding.

After the mounting portion is fixed and the siding strip is set to the position shown, the act of securing the next mounting portion 230 ′ (above the mounting portion 230) causes the siding strip 210 to be clamped. Indeed, the emphasis 235 ′ of the second mounting part is placed close to the siding strip 210, preventing any displacement in the direction of slipping of this strip. Thus, the emphasis 235, 235 ′ performs a dual function of clamping and spacing adjacent strips relative to each other.

When this at least one stop 225 ′ is removed, for example by crushing, access to the lower siding strip 210 is freed up, which can then be moved up again and removed. After placing a new siding strip on the mounting part, it is possible to fix, for example, by gluing, at the place of the initial stop 235 ′, a spacer of the same size and again clamp the siding strip.

In FIG. 5, 6 and 7 depict a particularly preferred rail element 320 of the present invention. In order to facilitate the centering of the rail elements during installation, the rail element 320 — preferably, is provided with a tongue 328 at one of its ends and a groove 329 at the opposite end thereof to accommodate the tongue of the adjacent rail element. Thus, the rail elements are fixed on their support end to end by inserting the tongue of one rail into the groove of the rail adjacent to it. This allows you to quickly mount in one row a rail containing a series of elements.

Figures 8 and 9 illustrate preferred embodiments of the mounting portion 330.

In order to facilitate the centering of the mounting parts 330 during installation, the tile base 331 - which is preferably - is provided with a tongue 337 on one of its ends and a groove 338 on the opposite end thereof to accommodate the tongue of the adjacent mounting part.

The preferred base tile 331 is preferably made in such a way that it has a central stiffener of a given thickness and thinning zones, which — preferably — form slopes descending from the central rib to the edges in order to facilitate removal of water accumulating in these parts.

Preferably, the preferred mounting portion 330 comprises at least one socket 336 for attaching an insert serving as a spare stop. An insert 350 of this type, depicted in FIG. 10, has fastening means 351 for inserting it into the corresponding socket 336. Thus, it is possible to replace the siding strip and fix the spare strip without gluing. This makes it easy to replace siding strips without removing adjacent strips.

FIG. 11 and 12 illustrate an alternative embodiment of the mounting portion 430 according to the above principle. The fastening means 440 includes two spaced pairs of legs 441 provided with spikes 442 on the upper side 439 of the base tile 431. The siding strip 410 shown in cross section in FIG. 13 and corresponding to the mounting part 430, has on its bottom side 411 two recesses 412, 413 arranged so as to be connected to the lock with two corresponding pairs of spikes 442.

Preferably, the rail element and / or mounting part forming part of the assembly of the present invention is made by injection molding of plastic or composite material into molds made for this purpose. It is preferable to use a polyamide RA, preferably with a fiberglass reinforcing filler. Other suitable reinforcing fillers are known in the art.

A preferred method for making the rail element and the mounting part forming part of the assembly of the present invention involves the extrusion of plastic or composite material. For this purpose, an extrusion head is made corresponding to the rail profile.

The advantage of using polymeric materials is the improved material properties with respect to dissimilar meteorological conditions such as heat or rain. In contrast to the wooden frames, on which most siding is fixed today, polymeric materials do not deform or deform only slightly, under the influence of heat or cold. Similarly, unlike wood, these materials can eliminate the risks of infiltration due to moisture, and at the same time provide a long siding life.

The assembly of the present invention also makes it possible to lay siding quickly and with high accuracy on horizontal or vertical surfaces and, in particular, facades. In the case of siding from wooden boards, they do not come into contact with other wooden elements, and since ventilation of the boards is ensured, they will last a guaranteed long time. Fasteners are not visible after installation.

In a typical case, the siding is completed using several rails, each of which is placed on one surface parallel to each other. Preferably, this at least one siding strip extends perpendicular to the rail line. Typically, the rail axes are spaced 60 cm apart. The thickness of the rail is typically 6 cm. In accordance with the above, the assembly of the present invention allows siding strips to be vented over a large part of the rail surface, which increases the siding life.

The present description does not limit the scope of legal protection of the present invention, which is found from the following claims of the present invention.
