Description

PANEL E.G. ADDITIONAL WINDOW MOUNTED AT THE AREA OF A WALL OPENING

The invention relates to a panel e.g. an additional window arranged at the area of a wall opening, said panel comprising a mounting frame of profile material having at least one base part of essentially U-shaped cross-section and a plate-shaped element e.g. a pane arranged therein by its rims, the base part being formed by a glass profile having an essentially L-shaped cross-section and a glass fillet connected herewith, the connection comprising a groove and an extension engaging said groove. Such a panel is known from DE-A 2537364. The extension of the connection is formed herein on the glas fillet and has two limbs which can be urged towards one another by elastic deformation of the glass fillet and be inserted in this state into the groove of the glass profile. At the elastic return into position one of said limbs snaps behind a rim of the groove wall. Since elastic material is necessarily used, the connection of the glass fillet with the glass profile can withstand only feeble forces. When the plate-shaped element is struck in the direction towards the glass fillet, the glass fillet risks being pushed out of the glass profile.

Object of the present invention is to provide a panel of the kind set forth in the preamble, which does not exhibit said disadvantages. In the panel according to the invention the profile material consists of a relatively inflexible substance and on its wall facing the interior of the U the extension of the connection has a cam profile which grips behind a cam profile on the opposite wall of the groove when the glass fillet deflects outwardly. Thus the connection becomes the firmer the heavier is the force exerted on the plate-shaped element in the direction towards the glass fillet. Under any condition the glass fillet remains connected with the glass profile until the material breaks down mechanically. An additional advantage is that in case of need the

OMPI glass fillet can be simply disengaged by deflecting it inwardly so that the connection is loosened and the glass fillet can be lifted out of the glass profile. The panel according to the invention may, therefore, be suitably used temporarily, for example, for additional protection of the window of a building. Then the plate-shaped element may be of an impact-resistant synthetic resin such as polycarbonate.

When the panel according to the invention comprises conventional glass, the glass can be very rapidly replaced in the case of a break-down without damaging the profile.

Owing to these properties the panel according to the invention is particularly suitable for additional protection in the form of an additional window or of a single window. It is furthermore suitable for use as an additional safeguard against burglary, if it is provided with impact-resistant synthetic resin and arranged behind an existing window or at any rate with the glass fillet on the inner side.

When the connection is proportioned so that, when the connecting parts are in engagement in the no-load state the glass fillet and the limb of the glass profile not connected with the former slightly converge towards the free ends, the glass fillet and said limb will be parallel to one another, when the pane is arranged in the profile with the interposition of flexible material, owing to the force exerted by the flexible material.

In order to enable mounting of panes of different thicknesses in the same profile, a strip connected by fastening members with at least the glass fillet is employed in accordance with the invention, said strip having a web, at least one resilient tongue protruding from said web and engaging the pane and a thickened part that can be readily torn away from the web. Up to a given thickness the pane can be retained by the thickened part of the strip. If panes of larger thickness have to be mounted, the thickened part is simply torn away from the strip so that more space becomes available.

The glass fillet preferably has a countersunk part at the area of the thickened part so hat the strip can even more effectively match the thickness of the pane.

According to the invention the depth of the

U-profile formed by the glass profile and the glass fillet is at least about three times the thickness of the pane. In this way it is avoided that the relatively elastic pane should be pressed out of the groove formed by the U-profile.

Further advantages and features of the invention will become apparent from the following description with reference to a few embodiments shown in the Figures.

Fig. 7 is a partly cut, perspective view of an additional window according to the invention in the mounted state. Fig» 8 is an elevational view corresponding to Fig.

Fig. 9 is a partly cut, perspective view of an additional window embodying the invention, partly dissembled to clarify the mode of mounting.

Referring to Fig. 1 , a glass profile 1 according to the invention essentially has the shape of an . The glass fillet 2 co-operating with said glass profile can be connected with the glass profile 1 by connecting means. The connecting means comprise a tongue 4 on the glass profile 1 and a groove 5 at the glass fillet 2. The inwardly extending wall of the tongue 4 is provided with a cam member 6 adapted to co-operate with a cam member 7 on the opposite wall of the groove 5.

Fig. 1 shows the relative positions of the glass profile 1 and the glass fillet 2 during mounting of the glass fillet 2. The glass fillet 2 is deflected towards the glass profile 1 and, when the cam members 6, 7 grip one behind the other, the glass fillet 2 can deflect outwardly, the connection established by the cam members 6, 7 maintaining the junction between the glass fillet 2 and the glass profile 1. The glass profile 1 and the glass fillet 2 are provided with members adapted to receive a strip 8 of flexible material shown in Fig. 2. The strip 8 comprises a web 13 provided with fastening members 9, which can be arranged in the receiving members 3. Tags 10 protrude in inclined positions from the web 8 to engage the pane in the mounted state. In the middle of the web 13 a thickened part 11 is connected with the strip 8 through a thin ridge 14. The thickened part 11 can be readily torn away from the web 13 of the strip 8 at the area of the thin ridge 14 along the line 12. As will be explained more fully hereinafter, the thickened part 11 serves to clamp panes of small thickness in the profile.

Fig. 3 shows how the glass fillet 2 is retained on the glass profile 1 owing to the engagement of the cam members 6 and 7. In the glass profile 1 and in the glass fillet 2 is arranged a strip 8, the thickened part 11 of which is torn away. The pane 16 is arranged between the strips 8. The profile shown can accommodate panes 16 of quite different thicknesses. The minimum thickness is designated by 17 and the maximum thickness by 18. In the case of the small thickness 17 the pane is clamped tight by the thickened parts 1, whereas in the event of larger thicknesses up to the maximum thickness 18 the strip 8 without thickened part is used. The glass profile 1 and the glass fillet 2 have a recess 19 at the level of the thickened part 11 so that the web 13 of the strip 8 can slightly bend outwardly.

Although the Figures show a connection having a tongue 4 on the glass profile and a groove 5 at the glass fillet 2, the tongue and the groove may be interchanged, whereas the^' connection may furthermore by established in a different way.

Fig. 4 shows a double additional window, in which the glass profile 21 essentially -has the shape of an inverted T. Each of the two limbs 22, 23 on either side of the standing limb can co-operate with a glass fillet 2 of the kind shown in Fig. 1. Not only for insulating purposes but also for safeguarding purposes the panes in the additional window may be used, for example, the pane 24 being of common glass and the pane 25 being a stratified pane comprising a layer 27 of tough synthetic resin such as polycarbonate and two glass panes 26 on either side thereof.

Fig. 5 shows a double additional window 30 corresponding to Fig. 4 which may be employed to replace a single pane. The ridge 31 provided on the glas profile 29 is mounted in the groove instead of the existing pane.

The additional window of Fig. 6 can accommodate three panes. The lower limb 38 of the glass profile 36 is _* prolonged. The panes 39, 40, 41 are mounted in this order. For the L-sec ion profile 36 glass fillets 37 are used, which have recesses 3 on their sides remote from the connection for receiving a strip for the next pane. At the end a glas profile 2 known from the above-described embodiments can be used. Also in this embodiment different kinds of panes may be employed, for example, a ball-resistant pane 39. The layer of polycarbonate is in this case appreciably thicker. As an alternative, a pane completely consisting of polycarbonate may be used. Since the U-section channel formed by the glass profile and the glass fillet according to the invention has a great depth, such a relatively flexible pane of polycarbonate cannot be deflected to an extent such that it would snap out of the U-section channel.

The additional window embodying the invention can be mounted in various ways. As is shown in Fig. 7, an additional window 15 can be arranged inside a window frame 40. In this frame 40 is already arranged a pane 44 by means of glass laths 42 and lute 44. The additional window 15 is

OMPI arranged by first mounting the glass profile with the aid of screws 43 in the frame and subsequently putting in place the pane and the glass fillet in the manner to be described with reference to Fig. 9. An additional window embodying the invention can be mounted not only inside a frame but also on a frame as is shown in Fig. 8. The frame 45 of Fig. 8 already has a pane 46, which is fastened therein with the aid of lute 46 and glass laths 47. The glass profile of the additional window is mounted on the frame 45 with the aid of screws 49, which are passed through the upright limb of the glass profile. Since after the additional window has been mounted the screws 43, 49 are inaccessible, the additional window can be mounted on the outer side in order to enhance protection against burglars.

As stated above, the thickened parts 11 retain the pane of small thickness in the additional window 15, as is shown in Fig. 7. The web of the strip 8 can bend at the area of the thickened part 11 into the recess 19. If the space enclosed between the existing pane 46 and the pane of the additional window 15 contains moisture, a condensate may be formed on one or on both panes so that the transparency is reduced. In order to avoid this undesirable phenomenon a slot 51 is provided in the strip 8 of flexible material located on the inner side so that the space between the two panes communicates with the Interior of the glass profile. Below in the glass profile 1 a desicating agent, for example, silicagel 52 is provided. The moisture between the panes or penetrating between them is absorbed by the drying agent 52 so that no condensate can form on the panes.

Fig. 9 shows the mode of mounting an additional window 15 embodying the invention. First a frame of glass profile 1 is made, the corners being mitred and corner connecting elements 55 being provided. This frame is mounted in or on the window frame in the manner illustrated in Fig. 7 or 8. Then a strip 8 is arranged in said frame and the pane 16 is mounted. Subsequently the glass fillets 2 are arranged in place. The upper and lower glass fillets have at both ends flattened parts 56 which come into engagement with the lateral glass profiles of the frame. The ends 59 of the lower and upper glass fillets are bevelled so that they accurately fit to the oblique part 60 of the lateral parts of the frame. After a strip 8 has been mounted, the upper and lower glass fillets are snapped into their places in the directions of the arrows 57 and 58 respectively. The additional window 15 is completed by arranging in place the lateral glass fillets (not shown) , which are accurately made to size and fit in between the lower and upper glass fillets. The lateral glass fillets need not have a flattened part of a bevelled edge.
