Description

Field of the invention

The invention relates to joineries intended to close a building bay, especially those of the sliding type, and more particularly relates to a glazing support module and a joinery comprising said glazing support module.

By the terms "sliding type joineries" is meant in this text all opening devices such as windows or doors comprising an opening adapted to slide in a frame.

State of the art

The sliding type joineries of the state of the art comprise an opening comprising a glazing enclosed in a frame composed of a lower cross member, an upper cross member and amounts abutting the lower and upper cross members.

Guiding members attached to the lower cross member slidably cooperate with guide members of a frame installed in a building bay, so that the leaf slides in the frame to open or close said bay.

A seal is generally disposed on the periphery of the glazing so as to wrap the sides of said glazing. This seal is held by the sleepers and uprights on the glazing.

The forces generated by the weight of the glazing are supported by the seal which transmits them to the guide members of the frame through the guiding members of the opening.

The lower beam is designed to transmit these forces while maintaining its rigidity, and therefore generally has a cross section of large size to withstand the mechanical stresses generated by these efforts. This results in a cost and a high weight of the opening.

In addition, the glazing being supported by the seal, it is not reliably immobilized, so that there is a significant risk that the glazing is gradually unbalanced, because of the large number of handling opening it to open or close the building bay.

The unbalance of the glazing usually causes localized forces on an area of the lower rail and / or amounts, causing a concentration of mechanical stresses. Such a concentration of mechanical stresses can cause deformation of the frame of the opening.

Another disadvantage of sliding type joineries is that it is necessary to make adjustments of the position of the opening after installation in the frame. In addition to being a waste of time, making these adjustments can lead to quality defects.

Presentation of the invention

The present invention aims to overcome the aforementioned drawbacks by providing a glazing support module designed to prevent deformation of the opening frame of a joinery, to maximize the life of said joinery.

Another objective is to offer a carpentry whose manufacture is fast and simple, to avoid quality problems due to unpredictable manufacturing and assembly.

To this end, the present invention relates, in a first aspect, a glazing support module of a joinery, intended to be fixed to a lower rail of said joinery, comprising guide members called "first guide members". The module also comprises a plate, intended when the module is attached to the lower rail, on the one hand to rest facing said cross by a pressure surface, and on the other hand to receive a sidewall of the glazing of the carpentry in support against an extrados surface, opposite to the intrados surface.

In particular embodiments, the invention also fulfills the following characteristics, implemented separately or in each of their technically operating combinations.

In particular embodiments of the invention, the support module comprises elastic locking members by means of which the module can be fixed to the lower cross member by elastic engagement, said resilient socket members being configured to support the weight of the frame of the joinery.

The present invention also relates, in another aspect, a joinery comprising an opening comprising a glazing enclosed by a frame comprising an upper cross member connected to a lower cross by two amounts, said opening cooperating with a frame.

The joinery comprises at least one glazing support module as described above, attached to the lower cross member, receiving the glazing resting against a plate, said module comprising first guide members cooperating with second frame guiding members.

The lower crossbar can be designed in a simple and light manner insofar as only the glazing support module (s) supports the resulting efforts on the weight of the glazing.

In addition, thanks to these characteristics, the forces generated by the weight of the glazing are regularly distributed over the support module or modules so as to avoid the concentrations of stresses that can lead to deterioration of the joinery. The position of the support modules is predefined during the manufacture of the joinery so that no adjustment is necessary during the installation of the joinery in a building bay.

Also, the particular design of the joinery makes it possible to reduce the number of pieces constituting said joinery, thus simplifying the manufacture of the carpentry and its installation in the building bay.

In particular embodiments, the invention also fulfills the following characteristics, implemented separately or in each of their technically operating combinations.

In particular embodiments of the invention, the glazing support module is fixed in a transverse orifice extending transversely in the lower cross member, said module bearing on the cross member by the intrados surface of the plate so as to be interposed between the glazing and the frame.

Thus, the cross is designed so that the support module bears against the frame while receiving support glazing. Advantageously, this orifice makes it possible to hold the support module in position, that is to say immobilize it.

The position of the orifice is determined so that the resulting forces of the weight of the glazing and the weight of the frame are distributed substantially identically on the support module or modules, so that no adjustment is necessary to balance the constraints generated. by the weight of the glazing when installing the joinery in the building bay.

In particular embodiments of the invention the glazing support module comprises a seal interposed between the intrados surface and the bottom rail.

In particular embodiments of the invention, the glazing support module comprises elastic locking members by means of which the support module is fixed to the lower cross member by elastic engagement, said elastic locking members being designed to support the weight of the chassis.

Thus, the assembly of the support module in the cross member can be achieved simply and quickly, avoiding quality problems resulting from assembly hazards.

In particular embodiments of the invention, the glazing support module comprises position adjustment members of the first guide members designed to move the first guide members.

These characteristics make it possible to adjust the position of the zones of contact between the opening and the frame, that is to say to adjust the position of the zones of application of the forces generated by the weight of the opening on the frame so as to be able to balance the distribution of the mechanical stresses applied to the frame, even if the support module or modules is or are immobilized in the lower rail.

In particular embodiments of the invention, the lower cross member comprises two lateral wings connected to one another by a branch. upper and lower arm, said upper and lower branches being arranged facing one another so as to form an internal cavity.

This particular design of the lower crossbar reduces the weight of the crossbar. Advantageously, the uprights and the upper cross member are designed in a similar manner so as to reduce the weight of the frame.

In particular embodiments of the invention, the upper branch is inclined relative to a horizontal plane.

Thus, in the case of presence of water between said upper branch and the side of the glazing, for example in the case of possible infiltrations of water or formed by condensation, the water is caused to flow by gravity.

In particular embodiments of the invention, at least one side wing of the bottom rail comprises a side channel formed by a side branch extending along the longitudinal axis.

Detailed description of the invention

The present invention relates to a glazing support module 40 of a joinery 10 of the sliding type. The joinery 10 comprises an opening 20 configured to cooperate in sliding with a frame 30 to be installed in a bay of a building.

The opening 20 comprises a glazing 21 enclosed in a frame forming a frame. The frame comprises an upper cross member connected to a lower cross member 22 by two uprights with which said cross members abut for example by welding or by screwing.

In the present text, the terms "lower cross member" and "upper cross member" are defined so that, when the opening member 20 cooperates with the frame 30, the lower cross member 22 is closer to the ground than the upper cross member.

The lower and upper crosspieces 22 are preferably formed respectively by a profile, for example obtained by extrusion, extending along a longitudinal axis. They include several internal cavities, as represented on the figure 1 , extending along this longitudinal axis to give them a significant thermal insulation capacity and a resistance to mechanical stresses applied to said sleepers necessary to maintain their rigidity.

The lower rail 22 comprises an inner side wing 220 intended to be arranged with regard to an interior environment of the building in the bay of which the joinery 10 is installed and an outer side wing 221 intended to be arranged with respect to an external environment of the building. building, as illustrated by the figure 4 which schematically represents a cross section of said cross. Said wings are connected to one another by at least two branches 222 and 223 arranged facing one another so as to form a median internal cavity 225, said branches being called "lower branch" 222 and " upper branch "223 in the rest of the text.

The upper branch 223 is intended to be opposite a side of the glazing 21 and the lower branch 222 is intended to be facing the frame 30.

As shown on the figure 1 , the lower cross member 22 comprises at least one through hole 226, for example made by machining, extending transversely in said cross, that is to say perpendicular to its longitudinal axis. Said at least one through orifice 226 may have a substantially parallelepipedal geometric shape and form a recess in each lower branch 222 and upper 223.

The through hole 226 of the lower cross member 22 is configured to receive the glazing support module 40 so that said module is opening on either side of the lower cross member 22 so as to be interposed in support between the glazing 21 and the frame 30, as represented by the Figures 3 and 4 .

In the embodiment of embodiment shown in figures 2 , 3 and 5 , the module comprises lateral flanks 41 connected to each other by end walls 42. The module is designed so that the lateral flanks 41 and the end walls 42 are adjusted, preferably with a low clearance mechanical, in the recesses when the module is installed in the lower rail 22.

The support module 40 comprises elastic locking members 43 with which it can be fixed to the cross member by elastic coupling. These elastic locking members 43 are arranged on the lateral flanks 41 and / or on the end walls 42 of the support module 40 and are, for example, formed by fixing lugs.

In the embodiments represented by the figures 2 and 5 these fixing lugs are adapted to deform elastically during insertion of the module in the through hole 226 of the lower cross member 22 and to return to their original shape once the module installed. These fastening tabs are sized to support the weight of the chassis via the lower cross member 22.

The support module 40 is designed to transmit the forces generated by the weight of the glazing 21 and the weight of the frame to the frame 30 against which said module is supported. More particularly, the support module 40 has the effect of ensuring the maintenance of the glazing 21 in a selected position while directly transferring the forces generated by the weight of said glazing 21 on the frame 30.

The lower crosspiece 22 preferably comprises at least two through-holes 226 arranged at a distance from one another along the cross-piece, so that the weight of the glazing unit 21 is uniformly distributed over a plurality of support modules 40.

The glazing 21 rests against the support modules 40 which are immobilized in position in the lower rail 22. The glazing 21 is fixed in a stable manner and is not likely to move relative to the frame.

In addition to the reliability of maintaining the position of the glazing 21 in the chassis, these characteristics make it possible to ensure an optimal distribution of the forces generated by the weight of the glazing 21 making it possible to avoid any deformation of the frame of the opening 20, in particular the deformation known as the "falling nose" by the skilled person.

The support modules 40 comprise first guide members 44 arranged between the lateral flanks 41 and the end walls 42.

For example, as represented by Figures 2 to 5 , the first guide members 44 may be wheels or rollers engaged in rotation about axes integral with each of the lateral flanks 41. The first guide members 44 are adapted to cooperate with second guide members 31 of the frame 30. figures 1 , 3 and 4 represent second guiding members 31 of the frame 30 formed by a guide rail.

Each support module 40 also comprises a plate 45 connected to the lateral flanks 41 and to the end walls 42 by a surface intrados forming a shoulder. When the module is introduced into the through hole 226 of the lower cross member 22, the shoulder is arranged facing the upper branch 223 and preferably bears against the latter so as to constitute a stop.

The plate 45 comprises an extrados surface, opposite to the intrados surface, against which a side of the glazing 21 is supported, as represented by the sectional view of the figure 4 .

Preferably, the intrados surface comprises a seal 46, as illustrated on the figures 3 and 5 adjoining the lateral flanks 41 and the end walls 42.

Advantageously, the upper branch 223 may be inscribed in a plane inclined by a few degrees with respect to a horizontal plane as illustrated by the figure 4 for example from one to five degrees to the outside of the building. Thus, in the presence of water between the upper branch 223 of the lower cross member 22 and the side of the glazing 21, for example in the case of possible infiltration of water or formed by condensation, the water is forced to flow. under the effect of gravity, towards the outside of the building.

Advantageously, the upper banche is connected to a lateral channel 227, as represented on the figures 1 , 3 and 5 , extending along the longitudinal axis, and intended to receive water flowing on the upper branch.

This lateral channel 227 may be formed by a lateral branch comprising a horizontal portion extending from the outer wing to a vertical portion, as represented by the figures 1 , 3 and 4 . By "horizontal portion" and "vertical portion" is meant that the portions of the lateral branch are respectively written in a substantially horizontal geometric plane and in a substantially vertical geometric plane.

The vertical portion may extend on a lateral portion of the glazing 21 so as to participate in maintaining said glazing 21 in the opening 20, as represented by the figure 4 .

Advantageously, the side branch may comprise one or more through holes (not shown in the figures) for the possible evacuation of water to the external environment of the building.

The plate 45 of the support module 40 advantageously has a variable thickness so that when the shoulder is in abutment against the upper branch 223 of the lower cross member 22, the extrados surface is inscribed in a substantially horizontal plane.

The plate 45 may comprise a through orifice 200 opening on the face and the face extrados face, as visible on the figure 4 . In the event of water infiltration, or formation of water by condensation, on the lower cross member 22, this through orifice 200 is provided to receive at least a portion of the water flowing on the upper branch 223 and is intended to direct it through the clevis to the outside of the opening by gravity.

The plate 45 of the module may comprise a tongue 47 configured to extend in the channel, as represented by the figure 4 .

This tongue 47 plays a keying role during the fixing of the support module 40 to the lower cross member 22. The tongue 47 also makes it possible to maintain the position of the support module 40 in the lower crossmember 22 and to distribute the forces resulting from the weight of the glazing 21.

Each lateral flange 220 and 221 of the cross member comprises side seals 228 and 229 intended to be arranged on either side of the rail of the frame 30, in a manner known to those skilled in the art.

Cladding profiles intended to cover the flanges of the lower cross member 22 may be fixed by elastic engagement with the wings, as represented by FIG. figure 4 .

In a manner known to those skilled in the art, a glazing section 201 can be fixed by elastic engagement between a trim section and the inner side wing 220, as shown in FIG. figure 4 . This profile glaze 201 allows the positioning and maintenance in position of the glazing 21.

Similarly, the uprights and the upper crossmember may also comprise trim profiles fixed by elastic coupling.

Each support module 40 may comprise adjustment members 50 for the position of the first guide members 44 designed to be able to move them relative to the lateral flanks 41 and / or with respect to the end walls 42. to move the first guide members 44 between two extreme positions so as to balance the distribution of forces, resulting in particular from the weight of the frame and the glazing 21, applied to the first guide members 44. A poor balancing efforts on the first guide members 44 can lead to a deformation of the frame of the opening 20 and eventually a break of said frame.

These adjustment members 50 may comprise a yoke 51 in which are mounted in rotation the wheel or wheels, adapted to slide between the lateral flanks 41 and the end walls 42 of the support module 40. The yoke 51 is integral with one of the end walls 42 by means of a screw-nut system, as represented by the figure 5 , configured to drive in translation the yoke 51 when the screw is rotated.

More generally, it should be noted that the modes of implementation and realization considered above have been described by way of non-limiting examples, and that other variants are therefore possible.
