Description

Field of the invention

The invention relates to joinery intended to close a building opening, in particular those of the sliding type, and relates more particularly to a joinery comprising a glazing support module.

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

State of the art

The sliding type carpentry of the prior art, includes an opening having a glazing enclosed in a frame composed of a lower cross member, an upper cross member and uprights abutted to the lower and upper cross members.

Guide members fixed to the lower cross member cooperate in sliding with guide members of a frame installed in a building opening, so that the opening slides in the frame to open or close said opening.

A seal is generally placed on the periphery of the glazing so as to wrap the sides of said glazing. This seal is maintained by the crosspieces and the uprights on the glazing.

The forces generated by the weight of the glazing are supported by the gasket which transmits them to the guide members of the frame via the guide members of the opening.

The lower cross member is designed to transmit these forces while retaining its rigidity, and therefore generally has a large cross section in order to withstand the mechanical stresses generated by these forces. 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 will be gradually unbalanced, because of the large number of manipulations. opening to open or close the building opening.

The imbalance of the glazing generally causes localized forces on an area of the lower cross member and / or the uprights, causing a concentration of mechanical stresses. Such a concentration of mechanical stresses can cause deformation of the sash frame.

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

Statement of the invention

The present invention aims to overcome the aforementioned drawbacks by proposing a joinery designed so as to avoid deformations of the opening frame, in order to maximize the life of said joinery.

Another objective is to offer a carpentry whose manufacturing is quick and simple, making it possible to avoid quality problems due to vagaries of manufacturing and assembly.

To this end, the present invention relates to a carpentry comprising an opening comprising a glazing enclosed by a frame comprising an upper cross member connected to a lower cross member by two uprights, said opening cooperating with a frame. The joinery comprises at least one glazing support module fixed to the lower cross member, receiving the glazing in support and comprising first guide members cooperating with second guide members of the frame.

The lower cross member can be designed in a simple and light manner insofar as only the glazing support module or modules supports the resulting forces 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 concentrations of stresses which 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 when installing the joinery in a building bay.

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

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

In particular embodiments of the invention, the glazing support module is fixed in a through hole extending transversely in the lower cross member, said module bearing on the cross member by a shoulder.

Thus, the cross member is designed so that the support module is in abutment against the frame while receiving in support the glazing. Advantageously, this orifice allows the support module to be held in position, that is to say its immobilization.

The position of the orifice is determined so that the forces resulting from the weight of the glazing and from the weight of the frame are distributed in a substantially identical manner on the support module (s), so that no adjustment is necessary to balance the stresses 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 shoulder and the lower cross member.

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

Thus, the assembly of the support module in the cross member can be carried out in a simple and rapid manner, avoiding the quality problems resulting from assembly hazards.

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

These characteristics make it possible to adjust the position of the contact zones between the leaf 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 leaf on the frame. so as to be able to balance the distribution of mechanical stresses applied to the frame, even if the support module or modules is or are immobilized in the lower cross member.

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

This particular design of the lower cross member makes it possible to reduce the weight of the cross member. Advantageously, the uprights and the upper cross member are designed in a similar manner so as to reduce the weight of the chassis.

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

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

In particular embodiments of the invention, at least one lateral wing of the lower cross member comprises a lateral channel formed by a lateral branch extending along the longitudinal axis.

Detailed description of the invention

The present invention relates to a carpentry 10 of the sliding type comprising an opening 20 configured to cooperate in sliding with a frame 30 intended to be installed in a bay of a building.

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

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

The lower 22 and upper crossbeams are preferably respectively formed by a profile, for example obtained by extrusion, extending along a longitudinal axis. They comprise several internal cavities, as shown in FIG. 1, extending along this longitudinal axis in order to give them a significant thermal insulation capacity as well as a resistance to the mechanical stresses applied to said crosspieces necessary for that they retain their rigidity.

The lower cross member 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 carpentry is installed 10 and an exterior side wing 221 intended to be arranged with regard to an exterior environment of the building, as illustrated in FIG. 4 which schematically represents a cross section of said crosspiece. Said wings are connected to each other by at least two branches 222 and 223 arranged opposite one another so as to form an internal cavity 225 median, said branches being called "lower branch" 222 and "Upper branch" 223 below.

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

As shown in FIG. 1, the lower cross member 22 comprises at least one through orifice 226, for example produced by machining, extending transversely in said cross member, 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 222 and upper 223 branch.

The through hole 226 of the lower crosspiece 22 is configured to receive a support module 40 for glazing 21 so that said module opens out on either side of the lower crosspiece 22 so as to be interposed in abutment between the glazing 21 and the frame 30, as shown in FIGS. 3 and 4.

In the embodiment shown in Figures 2, 3 and 5, the module comprises lateral flanks 41 connected to one another by end walls 42. The module is designed so that the lateral flanks 41 and the end walls 42 are adjusted, preferably with little mechanical clearance, in the recesses when the module is installed in the lower cross member 22.

The support module 40 comprises elastic casing members 43 by means of which it can be fixed to the crosspiece by elastic casing. These elastic casing 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 FIGS. 2 and 5, these fixing lugs are adapted to deform elastically when the module is inserted into the through hole 226 of the lower crossbar 22 and to resume their initial shape once the module installed. These fixing lugs are dimensioned 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 by the weight of the frame to the frame 30 against which said module is pressed. More particularly, the support module 40 has the effect of ensuring the maintenance of the glazing 21 in a chosen position while directly transferring the forces generated by the weight of said glazing 21 onto the frame 30.

The lower cross member 22 preferably comprises at least two through holes 226 arranged at a distance from each other along the cross member, so that the weight of the glazing 21 is uniformly distributed over several support modules 40.

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

In addition to the reliability of holding the glazing 21 in position in the frame, 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 by the designation of “nose drop” by the person skilled in the art.

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

For example, as shown in FIGS. 2 to 5, the first guide members 44 may be wheels or rollers engaged in rotation around 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 show second guide 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 lower surface forming a shoulder. When the module is introduced into the through hole 226 of the lower crosspiece 22, the shoulder is preferably in abutment against the upper branch 223 of the lower crosspiece 22 so as to constitute a stop.

The plate 45 comprises an upper surface, opposite the lower surface, against which a side of the glazing 21 is pressed, as shown in the sectional view of FIG. 4.

Preferably, the lower surface comprises a seal 46, as illustrated in FIGS. 3 and 5, adjoining the lateral flanks 41 and end walls 42.

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

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

This lateral channel 227 can be formed by a lateral branch comprising a horizontal portion extending from the outer wing to a vertical portion, as shown in FIGS. 1, 3 and 4. This is understood by "horizontal portion" and by "vertical portion" that the portions of the lateral branch are respectively inscribed in a substantially horizontal geometric plane and in a substantially vertical geometric plane.

The vertical portion may extend over a lateral part of the glazing 21 so as to participate in the maintenance of said glazing 21 in the opening 20, as shown in FIG. 4.

Advantageously, the lateral branch may include one or more through orifices (not shown in the figures) allowing the possible evacuation of water to the outside 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 upper surface is inscribed in a substantially horizontal plane.

The plate 45 may comprise a through orifice 200 opening out on the lower surface and on the upper surface, as visible in FIG. 4. In the event of water infiltration, or of water formation by condensation, on the lower crosspiece 22 , this through hole 200 is provided to receive at least part of the water flowing on the upper branch 223 and is designed to direct it through the yoke to the outside of the opening by gravity.

The plate 45 of the module can include a tongue 47 configured to extend in the channel, as shown in FIG. 4.

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

Each lateral wing 220 and 221 of the cross member comprises lateral joints 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.

Cover profiles intended to cover the wings of the lower cross member 22 can be fixed by elastic fitting into said wings, as shown in FIG. 4.

In a manner known to a person skilled in the art, a glazing bead profile 201 can be fixed by elastic fitting between a covering profile and the inner side wing 220, as shown in FIG. 4. This glazing bead profile 201 allows positioning and keeping the glazing 21 in position.

Likewise, the uprights and the upper crossmember may also include trim profiles fixed by elastic fitting.

Each support module 40 may include 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 relative to the end walls 42. These adjustment members 50 allow to move the first guide members 44 between two extreme positions so as to balance the distribution of the forces, resulting in particular from the weights of the frame and the glazing 21, applied to the first guide members 44. Poor balance of the forces on the first members guide 44 may result in a deformation of the frame of the opening 20 and ultimately a rupture of said frame.

These adjustment members 50 may comprise a yoke 51 in which the wheel or rollers or rollers are mounted to rotate, 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 shown in Figure 5, configured to drive in translation the yoke 51 when the screw is rotated.

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