The platens of one pair are secured to the platens of the other pair, on opposite sides of the door, by tightening elements which can be straps whose ends are interconnected by screw-threaded bolts, or long screw-threaded pins in the case of a narrow door. Covering bands are slidable in slideways on the platens to cover the platens and tightening elements, and stops are detachably secureable to the edges of the doors to retain these covering bands.

Description

Device forming a strip which can serve as a lock support for doors or panels, in particular in glass.

The present invention relates generally to a device forming a strip which can serve as a lock support for doors or flat panels, in particular in glass. We have already described, in French patent 76-14.582 a device allowing the fixing of a lock applied to a glass or glass door without having to cut out the door, this device comprising for this purpose a metal belt or equivalent material, completely surrounding the leaf or leaf of the door at the mounting height of the lock, this belt having at least one solution of continuity for its tightening around this leaf of the door, with a view to keeping it in place by friction. Said belt then has means for receiving the lock.

The advantages which result from the elimination of the operations required to provide one or more cutouts in such a glass or ice door are obvious; it should also be added that certain safety glass panels are very difficult to work and therefore lend themselves very poorly to the production of such cuts.

We have also described, in the French Addition Certificate 76-37.267 relating to the aforementioned patent, means allowing the supply of an electric lock mounted on this belt in all the positions of the door and elastically compensating for the differences resulting the angular movement of the door when it opens.

It is however necessary, in practice, to be able to carry out the adaptation of devices of this type on doors or panels having very different dimensions. This would require, with known means, either the storage of finished products according to many dimensions, with the investments that this implies, either the manufacture or the adaptation of the belt each time according to the door or panel dimensions encountered, which obviously increases the equipment costs of doors or panels using the belt.

Furthermore, to ensure perfect immobilization of the belt on the door, it is understood that a certain tightening force is required, in particular in the vicinity of the discontinuity provided in the belt for this tightening. In order to allow the absorption of these forces by the belt, the latter must have a certain mechanical resistance, therefore a certain thickness. Now on the one hand it can result, in the case of relatively large or wide doors or panels, a relatively high belt weight, and on the other hand an increase in thickness, with as a consequence an increase in rigidity, which is unfavorable in the parts of the belt enclosing the edges of the door or of the panel, places where one must have on the contrary a better adaptability of the material to the edge of the glass.

The object of the invention is to provide a solution to the problem thus posed and to allow the production of an adaptable device, from a very small number of standardized parts, to a very wide range of door or panel dimensions. in ice, while providing the required properties of lightness and mechanical resistance in the parts subjected to the clamping forces.

The invention is embodied in a device forming a strip which can serve as a lock support for doors or flat panels, in particular in glass, characterized in that it comprises two pairs of rigid plates, the plates of each pair being joined together by a strip curved on itself in a U, fixed by its edges on each of the plates, said plates also carrying attachment means, members for tightening by traction, adaptable between the plates of the two pairs above, means for adjusting the length of these members, so that when the pairs of plates are fitted on the opposite marginal parts of a door or a panel in a position such as the strip connecting the two plates of a pair grips one of the edges of the door or of the panel, the adapted members between the plates can be adjusted to tighten these strips on these edges thus blocking the device on the door or the panel, profilings forming slides, provided on the edges of the plates, and a strip provided with lateral profiling adapted to the profiling forming slides of the plates and engaging on said profiling. The members for tightening by traction can be constituted by elements forming tie rods or equivalent means. According to a possible embodiment, the plates have at least one and preferably two rows of attachment means such as claws or holes, and there is provided, for each row of attachment means, a tie rod which can come in taken with said means by holes or claws respectively, and comprising length adjusting means for clamping the device around the door or the panel.

An embodiment which seems advantageous consists in providing, for each row of means for hooking the plates, a tie in two parts, the adjustment means, constituted for example by a bolt or a threaded rod, being provided between these two parts of the tie for tighten the device around the door or panel. The two parts of the tie rod are advantageously constituted by strips which can slide one inside the other, which at the same time ensures that these two parts are maintained in an alignment relationship.

It is of course possible to provide on each plate, for each row, a single claw or a single hole, and on the tie rods several holes or claws, or conversely several claws or holes in each row of the plates and a single hole or a single claw on parts of pulling, but better adaptability and better distribution of forces as well as better alignment between the plates are obtained by providing, as indicated, rows of claws or holes both on the plates and on the tie rods. It is easily understood that it is thus possible, from a set of pairs of plates, to cover very different widths of doors or panels, by adapting the position of the tie rods. In such a case, the adaptation may require the possible replacement of the tie rods, but these are then inexpensive parts. The strip profile is simply cut to the required length from large lengths of profiles in stock.

In the case of narrow panels, it is also possible, if necessary using narrower plates, to tighten the device around the edges of the panel by means of threaded rods extending between hooking elements such as lugs provided on the plates and placed opposite one another. The use of threaded rods here again makes it possible to adapt the width easily and inexpensively.

The fixing of the curved U-shaped strips on the plates can take place in any desired manner, for example by welding, riveting, etc. A solution that seems judicious consists in providing in the plates of the lights in which tabs or equivalent parts of the strips are engaged, judiciously from the inside, these legs being folded against the outer face of the plates for their fixing. In this way, a strap fastening is able to effectively resist the tensile forces exerted for tightening.

According to another particular feature, the plates judiciously have attachment means for elastic members for retaining a movable cable for supplying an electric lock, as described in Certificate of Addition 76-37.267.

In the case of a door, one of the plates or pairs of plates carries means for mounting a lock and / or a door handle. A solution that seems judicious consists in attaching to this plate or these plates, by welding or in a similar manner, bars or similar supports provided with threaded studs receiving the trunk or base of the lock or of the handle.

According to an advantageous feature, the plates have, towards their fixing edge of the curved U-shaped strips, lugs or equivalent parts, and there is provided for each plate a rod forming a stopper extending over the entire height of the plate or strip and against which this strip comes to bear by its corresponding end. These stops or rods thus close the strip at its ends, providing for the entire device in the mounted position a satisfactory aesthetic appearance. They also ensure the longitudinal positioning of the strips.

The upper and lower profiling of the plates are judiciously constituted by wings folded obliquely towards the outside, and the strip advantageously has on its edges a part at right angles and a part in dovetail which can engage by sliding on these wings. turntables. This provides easy installation of the strip cut to length, as well as good retention in a plane transverse to the door or panel.

It goes without saying that the space thus created inside each strip can receive all the elements necessary for example for controlling a lock, whether it is a simple electrical control by cable, an opto-electronic command or a command by magnetic identification or other. References from one face to the other of the door or panel are carried out in this case inside the device, between the glass and the strips. If desired, a material preventing slippage can also be inserted between the plates and / or the strips and the ice. The description which follows, made with reference to the appended drawings, given without limitation, will allow a better understanding of the invention.

Fig. 1 is a partial schematic representation in elevation of a door equipped with the device according to the invention.

Fig. 2 is an elevational view on a larger scale with cutaway corresponding to an embodiment. Fig. 3 is a sectional view on the line III-III in FIG. 2.

Fig. 4 is a sectional view through the line IV-IV in FIG. 2.

Fig. 5 is a view similar to FIG. 2 but corresponding to a variant.

Fig. 6 is a sectional view through the line VI-VI in FIG. 5.

In Fig. 1, there is designated by the reference 1 a glass door, which is mounted between two panels 2, 3 and on which is adapted a device according to the invention, the strip of which is visible at 4, this device comprising a handle 5 provided a lock entry 6, a keeper 7 being fixed on the panel 2.

In Figs. 2 to 4, the same elements as those visible in FIG. 1 have been designated by the same references.

We see in these figures that the device comprises two pairs of plates 8, 9. The plates of each pair have a generally rectangular shape. They are made of a rigid material, for example metal of sufficient thickness to provide the rigidity and resistance required to withstand the clamping forces. They are provided on their upper and lower edges (when looking at the plates in the mounted position) with a profiling formed each time by a wing 10 inclined towards the outside, the role of which will be indicated below.

The plates present towards a vertical edge lights 11 through which are engaged from the inside (also in the mounted position) the legs 12 of a strip 13 curved in a U shape, which is intended to surround an edge of the glass door 1 as is clearly visible in Figs. 2 and 3. The tabs 12 carry out the strap fastening on the plates and are fixed to them by welding or riveting for example.

Thus, towards each vertical edge of the glass door, there is provided a crew comprising two plates 8 or 9 placed on either side of the door and connected together by a strip 13 curved in the shape of a U, enclosing the vertical edge of the glass door 1.

According to the embodiment shown, each plate 8, 9 carries two rows of claws 14, arranged here towards the upper and lower edges of the plates in the mounted position, these rows being parallel to these edges. For the assembly of the device around the door 1, there are provided on each side of this door two tie rods 15, each of which is constituted by two strips 16 having a U-shaped profile to give them better rigidity and provided in their base with punctured or holes 17 according to a pitch corresponding to that of the claws carried by the plates. According to the embodiment shown, a strip carries a guide 18 in which the other strip can slide freely. A short threaded rod 19 associated with a nut is provided for tightening between the ends of the strips.

It can be seen that, with the arrangement described so far, using a very small number of standardized parts, it is possible to adapt a device according to the invention to doors of very different widths. It is indeed sufficient, for this adaptation, to mount the strips on the plates by hooking in a position taking account of the width of the door, the final tightening being carried out by means of threaded rods 19. The rigidity of the plates and their resistance provide a robust assembly, ensuring good fixing, and more flexible straps make a good fit around the edges of the door. It suffices, possibly for doors of unusual width, to use other strips, for example longer, without having to use other plates. The cooperation of the sets of holes in the strips with the rows of claws of the plates also ensures the alignment of the plates with one another.

According to the embodiment shown in FIG. 2, there have been reported on one of the plates 8 of a pair, more especially on the plate directed towards the external face of the door, bars 20 fixed for example by welding, which each carry two threaded studs 21. These studs are used for mounting on the plate a lock which is indicated schematically in dotted lines at 22 in FIG. 2. The handle 5 is itself fixed on this lock.

The method of mounting the strips 4 on the assembly thus adapted by clamping on the door is better visible in FIG. 4.

We see in this figure that each strip 4 comprises, towards its upper and lower edges, a profiling comprising a flange 23 perpendicular to the main plane of the strip and extending substantially up to the glass of the door in the mounted position, and a wing oblique 24 facing inward. The strips 4 can be engaged on the aforementioned assemblies, more particularly on the plates 8, 9, by sliding the wings 24 on either side of the wings 10 of the plates, which serve as slides.

It will be appreciated that the method of mounting the strips in place is thus simplified as much as possible. the positioning of the strips 4 in the longitudinal direction is ensured at each end of these strips by two stop strips 25, which each time cover the end of the cavities formed between the strips 4 and the plates 8, 9, by interlocking partly in these cavities, which ensures an aesthetic finish on the sides of the door. These stop rods are here fixed by means of screws

26 coming to cooperate with tapped holes (not shown) provided in tabs 27 carried by the plates 8, 9.

There is shown in FIG. 2, in each of the plates, two rows of punctures 28 which can be used for hanging elastic return members of a movable cable in the case of the use of an electric lock.

The variant embodiment shown in FIGS. 5 and 6 is intended to allow mounting on panels of very small width, for example on return panels of door drums. In this case, two plates 29, 30 of smaller width are provided, conjugated as in the previous embodiment to strips 31 which enclose the edges of the glass panel and connected to the plates in the same manner as above.

In the embodiment considered, the plates bear on their edges opposite the tabs 32, and the device is tightened around the panel by means of threaded rods 33 passing through these tabs and nuts 34.

The strips 4 are mounted and positioned longitudinally in the same manner as in the case of the previous embodiment, and the same references have been used in FIGS. 5 and 6 to designate the corresponding elements.

It is thus seen that the invention allows a universal adaptation of strips on doors or glass panels of very different dimensions, from a small number of standardized elements, that is to say in a way simplifying the assembly and limiting manufacturing costs and storage investments. Only the strips, which can be manufactured in the form of very long sections, then need to be cut to the required length.

Modifications can be made to the embodiments described, in the field of technical equivalences, without departing from the invention.
