Description

The invention relates to an anti-heaving device for door, window, window or similar joinery, having an outer side and an inner side, and defined by at minus a fixed or movable frame inside which is embedded a panel, in particular a glazing, coming on the wall, on its side outside the door, window or the like, against a shoulder that includes said frame.

The present invention will find its application in the field the manufacture of joinery such as doors, windows, display cases or the like and relates, more in particular, a device intended to prevent the heaving of a panel, in particular a glazing, out of sound frame.

We already know carpentry with a frame usually resulting from the assembly of profiles and, in which is embedded a panel, in particular a glazing.

In this regard, it will be observed that such a framework usually comprises, a shoulder against which bears the external side of said panel when placed in said frame. This last receives, in particular by clipping, a barrier capable of cooperating with the internal side of said panel to ensure immobilization and finalize the mounting of the latter in said frame.

It should be noted that, under the effect of a strong wind, a panel, more particularly glazing, tends to deform and exert pressure on said barrier which is likely to become detached from the frame which results in a loosening of said panel. Such heaving can, also, to intervene because of the deliberate action of a sharpening during a break-in attempt.

In order to remedy this heaving problem, it was imagined to interpose a bead of glue between the shoulder of the frame and said panel. This effectively resolves the heaving problem but causes a number of new problems, especially when it comes to replacement of said panel because, to do this, it is necessary to cut said bead of glue.

In this regard, it will be observed that such a cord is, generally, completed by a seal, again interposed between the frame and said panel, and coming to bear against the latter. Also, when cutting the bead of glue, it is common to score said seal which then needs to be replaced. A such a replacement can be either possible, but expensive, when said seal is of an interchangeable nature, either impossible when such a joint is obtained by coextrusion with the profile defining said frame.

In addition, in the particular case of a fixed chassis not removable to secure the new panel, it should install a new bead of glue which has tendency to sink, especially under said panel, which reduces strongly any possibility of subsequent replacement of this latest.

Another solution is to interpose, between the song end of said panel and the frame rebate, an angle reinforcement, associated with the latter, and comprising a wing perpendicular extending to the rear of said panel, on the side internal of the latter. It will be observed that the establishment of said angle requires maintaining a certain clearance between the edge edge of said panel and the frame rebate. To to hide the presence of this angle, the frame receives, still, a barrier against the rear of said panel.

This solution allows lateral support of said panel, this the latter being, however, in no way maintained in the plan of the glass due to the presence of a clearance between the panel and the rabbet. Also, during a break-in attempt, a malandrin is likely to lift said panel and provide heaving, out of said angle.

Such a drawback is found, for example, in the mode of realization as described in document DE-U-298 11 261.

In particular, it is a simple angle which, once the glazing of a door, window or the like arranged in its frame, has a wing that comes to apply on the internal side of this glazing, while the wing which is perpendicular to it and which extends from the internal side to the dwelling is perforated with orifices for the passage of fixing screws coming to be housed in the thickness of this frame. In particular, when this is designed in PVC and includes, internally, a metal reinforcement, the fixing screws, preferably of the self-piercing type, are defined capable of engaging with this metallic reinforcement.

Therefore, the glazing in the anterior solution, presents relative mobility with respect to the support angle so that the heaving with respect to the latter remains possible.

The present invention overcomes the disadvantages of state of the art devices through a new particularly clever anti-heaving device.

To this end, the present invention relates to an anti-heaving device for door, window, display cabinet or similar, having an outer side and an inner side, and defined by at least one fixed or movable frame inside which is embedded a panel, in particular a glazing, coming in applies, on its outer side against a shoulder that has said frame, characterized in that said device is consisting of a pre-frame adopting the shape of at least one blade made integral, by gluing, of said panel, at the edge peripheral of the latter and on the internal side, said blade being extended on this internal side by at least one tab capable of secure said device to the frame.

According to another characteristic, said fixing lug has an orifice for the passage of a fixing member, in particular a screw or the like, on the one hand, accessible from the side internal door or other and, on the other hand, intended for cooperate with said frame, in particular with a metal reinforcement that internally, the latter.

Another characteristic of the present invention relates to the the fact that said fixing lug comprises means for fixing, in particular of the clip-on type, capable of cooperating with additional fixing means that the frame of the door or the like.

An additional characteristic concerns the fact that said orifice is provided at the level of an extending fixing tab, from said blade, substantially perpendicularly to the latter and to the plane of the said panel, in the rebate of the frame.

According to another characteristic, said fixing lug extends, from said blade, substantially perpendicular to the latter and to the plane of said panel, said fixing lug comprising a return at which said orifice is formed, this return extending, on the one hand, parallel to the plane of said panel and in a direction opposite to the latter, and, on the other hand, to the rear of the frame and on the inner side of the door or the like.

An additional feature of the present invention relates to the fact that said blade comprises, at its free end, a return oriented towards said panel.

According to an additional characteristic, said blade is completed by a wing extending, on the one hand, so perpendicular, from this blade, in one direction opposite to that of the bracket and, on the other hand, in direction of the external side of the door or other and at the level of edge edge of the peripheral border of said panel.

In fact, this wing has a width greater than the thickness of said panel so that its free end protrudes from the front of said panel, on the outside of the door, or analogous, and constitutes a stop capable of cooperating with the shoulder of said frame.

An additional feature concerns the fact that the free end of said wing has an extending return parallel to the plane of the panel.

According to another characteristic of said device, said pre-frame is defined by at least one section portion comprising, at minus, a blade and a mounting bracket.

Finally, said device can be completed and concealed by a covering profile, in particular in the form of a barrier or the like, capable of cooperating with said frame, on the internal side of the door or the like. Preferably, this profile covering also defines sealing means in periphery between said panel and its frame.

The present invention therefore consists of a panel, in particular glazing, to which a frame and component is attached, with the latter, a set intended to be embedded in a frame. This assembly abuts against a located shoulder, at said frame, on the external side of the door. The panel, on its internal side, is glued against a rendered blade integral with said frame. It is, therefore, carried out a lateral support of said panel.

In addition, the fact, on the one hand, of sticking said panel on said anti-heaving device and, on the other hand, to fix this last on the frame advantageously allows to maintain said panel in his plan.

Thus, the device according to the invention ensures a effective multidirectional holding of said panel inside of the frame and prevents its release, involuntary under the effect strong or willful wind breaking in.

This device allows, however, a voluntary withdrawal of said sign authorizing an authorized person to access, from the internal side of said panel, to the fixing member of said device on the frame. By removing said organ from fixing, it is possible to remove the panel-frame assembly out of its scope to proceed with its replacement.

Other objects and advantages of the present invention will become apparent during the description which follows whose understanding will be facilitated by referring to the attached drawings.

Figure 1 is a schematic view in elevation of a door or the like comprising a frame in which is embedded a panel, the latter being associated with an anti-heaving device according to the invention.

FIG. 2 corresponds to a schematic representation, partial and sectional view of the detail identified A in FIG. 1 and shows an anti-heaving device according to a first mode of production.

FIG. 3 is a diagrammatic view, in perspective and in exploded, of the anti-heaving device shown in Figure 2.

Figure 4 is a view similar to Figure 2 and corresponds to a second embodiment of an anti-heaving device.

The present invention will find its application in the field the manufacture of joinery such as doors, windows, display cases or the like and relates, more in particular, a safety device able to equip these.

As shown in Figure 1 of the accompanying drawing, such door 1, window or the like is usually present under the form of a sleeping frame 2 on which is mounted, articulated, a opening 3. The latter is usually defined by a frame 4 made of wood or resulting from the assembly of metal profiles 5 or synthetic material, and inside which is embedded a panel 6, in particular a glazing 7, extending in a plane P.

If, in the following description, it will be more particularly, refers to a door 1 or the like, the present invention also applies to a fixed frame such than a display case, which also has a frame inside which is embedded a panel defined by glazing.

As shown in Figures 2 and 4, such a door 1 or other has an external side 8 as well as an internal side 9 oriented outward and inward, respectively of a building, a point of sale, a store or other equipped of such a door 1 or other.

In these same figures, a panel 6 has been shown embedded in a frame 4. The latter comprises, on the outer side 8 of door 1 or other, a shoulder 10 against which said panel 6 is applied, especially when it is mounted in said frame 4. Such a shoulder 10 advantageously has a seal 11, attached to this frame 4 or coextruded with the latter, and coming to bear against said panel 6.

The invention consists in that said door 1 or the like is fitted with a safety device 12 of the anti-heaving type, intended to oppose heaving, involuntary or maliciously, of panel 6 out of its frame 4 reception.

Such an anti-heaving device 12 is, however, and advantageously, designed capable of allowing withdrawal voluntary, by an authorized operator, of said panel 6 outside of its frame 4, in particular with a view to its replacement.

According to the invention, said anti-heaving device 12 is consisting of a frame 13 made integral, by gluing, of said panel 6, at the peripheral edge 14 of the latter and on the side internal 9 of door 1, window or the like.

It should already be pointed out that the concept of precadre must be seen in a very broad sense since, as this will emerge from the description which follows, the preceding box, object of the invention can be summarized in simple sections of profiles, of reduced length, glued on the periphery on the panel 4.

In fact, such a frame 13 has the shape of a blade 15 glued to said panel 6 and extended, on the internal side 9 of the door 1 or other, by at least one tab 16 intended to ensure fixing said anti-heaving device 12 to the frame 4. As shown in Figures 2 and 4, such a tab attachment 16 extends, from said blade 15, to the rear said panel 6, on the internal side 9 of the door 1 or the like.

According to a first embodiment not shown, said fixing lug 16 comprises fixing means suitable for cooperate with additional fixing means that presents said frame 4 of door 1 or other.

Such fastening means can, for example, be of the type clip and / or step.

However and according to a preferred embodiment, said tab fixing 16 has an orifice 17 for the passage of a fixing member 18, in particular a screw or the like.

As shown in Figures 2 and 4, said anti-heaving device 12 is designed in such a way that its attachment 18 can be accessible, for an authorized operator, on the internal side 9 of the door 1 or other, behind said panel 6.

In fact, this fixing member 18 passes through said orifice 17 to cooperate with frame 4, in particular with a reinforcement metal 19 that internally comprises the latter.

It will be observed that such cooperation authorizes a immobilization of said panel 6 relative to its frame 4 and particularly, and advantageously, prevents all movement of said panel 6 in its plane P.

With regard, more particularly, to said tab attachment 16, this extends from said blade 15, substantially perpendicular to the latter, to the rear of said panel 6 and the internal side 9 of door 1 or other.

This blade 15 being glued to said panel 6, it extends in a plane substantially parallel to the plane P of said panel 6. As a result, said fixing lug 16 extends in a plane substantially perpendicular to that P of said panel 6 and, as visible in FIGS. 2 and 4, is preferably located in rebate 20 of said frame 4.

According to a first embodiment shown in FIGS. 2 and 3, said orifice 18 is formed directly at the level of said fixing lug 16 extending substantially perpendicular to plane P of panel 6, in particular in rebate of frame 4.

According to another embodiment shown in Figure 4, said fixing lug 16 has a return 21 extending from of the free end 22 of said fixing lug 16, of parallel to the plane P of said panel 6, and in a opposite direction to the latter. In fact, such a return 21 comes position at the rear of the frame 4, in particular against this last, and on the inner side 9 of the door or the like. It is, more particularly, at the level of this return 21 which is provided said orifice 17.

According to an additional feature of the present invention and as visible in FIGS. 2 to 4, the blade 15 of the anti-heaving device 12 has a free end 23 provided with an oriented return 24, in particular so perpendicular, towards said panel 6.

Such a return 24 is designed, on the one hand, capable of ensuring a spacing 25 between panel 6 and blade 15 of the device anti-heaving 12, in this spacing 25 coming to take places a bead of glue 26 capable of ensuring the bonding of said blade 15 on the panel 6. This return 24 is, on the other hand, designed suitable for retaining the adhesive of the cord 26 so as to avoid its flow, in particular during the installation of said blade 15 on panel 6.

Another characteristic of the present invention relates to the the fact that said blade 15 is completed by a wing 27 extending perpendicularly from this blade 15, in a direction opposite to the fixing lug 16. In done, this wing 27, after the installation of said device anti-heaving 12 on the panel 6, extends towards the external side 8 of door 1 or other and at the edge end 28 of the peripheral edge 14 of said panel 6.

As shown in Figures 2 and 4, said wing 27 is made integral with said panel 6, in particular through a portion of the adhesive bead 26. This portion ensures the bonding end edge 28 of said panel 6 on wing 27 of anti-heaving device 12.

According to a preferred embodiment of the present invention, said wing 27 has a width 29 greater than the thickness 30 of said panel 6, if necessary corrected for spacing 25. Also, after the installation of said anti-heaving device 12 on the panel 6, said wing 27 extends in direction of the external side 8 of the door 1 or the like and has a free end 31 projecting from the front of said panel 6. As visible in FIG. 4, this free end 31 advantageously defines a stop capable of cooperating with the shoulder 10 of said frame 4 in order to guarantee the positioning, inside the latter 4, of said panel 6.

Reference is now made to FIG. 3 corresponding to a view exploded view of the panel 6 and of the anti-heaving device 12, before the installation of the latter at the edge peripheral 14 of said panel 6.

In this FIG. 3, it will be observed that the bead of glue 26 is located at the level of the blade 15 and / or of the wing 27. This the latter is supplemented by means 32 capable of ensuring spacing between the latter and the end edge 28 of said panel 6, this in order to allow the establishment of a appropriate amount of glue, suitable for fixing effective of the panel 6 on said wing 27, while avoiding its evacuation by crushing. Such means 32 can be constituted by a suitable shim.

As shown in Figure 4, the free end 31 of said wing 27 can advantageously be fitted with a return 33 extending parallel to the plane P of said panel 6 and direction of the latter. Said return 33 is, in fact, designed suitable for retaining the adhesive of the cord 26 so as to avoid flow, at the free end 31 of said wing 27, likely to cause sticking of the anti-heaving device 12 on frame 4.

In this figure 3, there is shown an anti-heaving device 12 adopting the shape of a profile 34, in particular in aluminum, extending over the entire length of the panel 6 to equip. It is obvious that the present invention is not in no way limited to such an embodiment and that such anti-heaving device 12 can be in the form at least one section of profile, associated with said panel 6, and comprising, at least, a blade 15 as well as a fixing lug 16.

The latter 16 may in fact be in the form a wing 35 extending at the rear of said blade 15 or else like one or more tabs.

Finally the anti-heaving device 12 according to the invention can also be completed with a covering profile 36, associated with said frame 4, located on the internal side 9 of door 1 or the like and behind said panel 6.

Such a covering profile 36 makes it possible to conceal the presence of said anti-heaving device 12 and adopts, for example, the form of a barrier 37 or the like.

Preferably, this trim profile further defines sealing means at the periphery between said panel 6 and its frame 4.
