Description

FIELD OF APPLICATION OF THE INVENTION

The present invention relates to the field of carpentry and including adaptations to achieve the connection in cross section between a cross and an amount in the best conditions.

DESCRIPTION OF THE PRIOR ART

The right cross-cut assembly has the advantage of simplifying the connection between the uprights and the crosspieces by allowing in particular a direct screwing of a workpiece to the other without the need for a connecting piece, a connecting piece necessary for a cut-off assembly. tab or miter.

It has the other advantage of allowing the use of different profiles for the uprights and sleepers which is impossible on a mitered mount. This flexibility in the choice of profiles makes it possible to adapt these as well to their function as to aesthetic considerations.

Nevertheless, if the mechanical connection can be considered facilitated, the meeting of different shapes can present aesthetic problems as well as implementation of function as important as the seal between the frame and the opening of a window.

In addition, because of the meeting of profiles and different volumes a straight section connection between two different profiles may have recesses likely to become the cause of infiltration.

The document WO 2006/025685 A1 describes a cross-sectional assembly of ties and amounts of a frame.

According to an example of a sleep frame formed of uprights and sleepers adopting different profiles, the shape of the profile of the crosspiece may not completely coincide with the vertical receiving surface of the profile of the amount then creating recesses likely to constitute pockets of moisture.

The encounter in straight section, that is to say in perpendicular positioning of two linear elements in fact constitutes volumetrically and functionally a stop, a source of unsightliness and rupture in the functions provided by the shapes of the profile. Thus, for example, if the profile of the cross member provides by means of an outer groove the support of a device covers seal, this groove is stopped at its sawed end and can not join the possible equivalent groove in the profile assembled perpendicularly.

These disadvantages are a major obstacle to a greater use of the cross-section assembly of profiles with or without a different aesthetic on the same assembly.

DESCRIPTION OF THE INVENTION

On the basis of this fact, the plaintiff conducted research aimed at simplifying cross-sectional assemblies.

This research led to the design of a connection resulting from a cross-section assembly or assembly of sleepers and uprights forming the frame of a frame of a sliding patio door, where the sleepers and uprights are formed of one or more profiles,
where the crosspieces and the uprights have faces facing the outside of the preformed frame to cooperate with the frame accommodating the bay window and faces oriented towards the inside of the preformed frame to cooperate with the sliding glass bay or windows,
where the ends of the cross members are cut in a plane substantially perpendicular to the longitudinal axis of the cross member defining a transverse bearing plane,

This feature is particularly advantageous in that it solves by the use of a plug, ie a patch that does not participate in fixing, the problems of volume inconsistency occurring during the meeting. ends to be assembled in straight section of two sets of profiles different constituting the amounts and crosses of a frame of dormant.

Indeed the plug, coming to be introduced along a longitudinal axis of a first set of profiles namely the amount and being preformed on its surface corresponding to the shapes of the second set of profiles arranged perpendicularly, ensures continuity of shapes where they stop to know at the level of the cutting planes. The complex forms of meeting volumes will thus focus on said plug which will come to plug and marry the shapes of the end of a first section and have a head whose side surface will come to plug and marry the open end of the another section, said cap having on one of the longitudinal axes of the profiles that connects a projection being introduced into the hollow core of one of the profiles and allowing its positioning and its holding in position.

According to a preferred embodiment, the profile of the amounts and the cross members are different.

In addition to the aesthetic continuity of the volumes, the connection obtained by the assembly of the invention is particularly advantageous in that it also ensures the continuity of some of the functions implemented by the preforming of the profiles which it ensures continuity.

Thus, according to another particularly advantageous characteristic, when the two sets of profiles adopt a groove capable of matching, said plug is preformed with one or more grooves to ensure continuity of the preformed grooves on the profile assemblies.

According to another characteristic, the cylindrical surface and the external surface of the head are preformed with a protruding shape adopting the profile of an L reproducing in their respective plane the profile of a fixing groove for a joint cover, preformed groove on the outer surfaces of the uprights and crosspieces with the plug ensures the junction.

According to another particularly advantageous characteristic, when the end of the crossmember does not exactly correspond to the shape of the surface of the end of the upright which receives it, one or more projections projecting from the head complete the volumes. left free by the transom end.

A plurality of material has been envisaged for producing this plug, such as an aluminum alloy, a plastic material, etc.

However, according to a preferred technological choice, said plug is made of polyphenylene oxide modified (ppom) material known under the trade name "noryl". Such a material has the particular advantage of supporting a hot lacquer allowing an aesthetic continuity between the profiles and the plug in accordance with the objectives of the invention.

The invention also relates to a frame or fixed window frame incorporating all or part of the characteristics described above.

The basic concepts of the invention having been described above in their most elementary form, other details and characteristics will emerge more clearly on reading the description which follows and with reference to the appended drawings, giving non-limiting example, an embodiment of a cross-section assembly according to the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

As illustrated on the drawings of Figures 1 to 4 , the window frame (a frame of which only a corner is shown), which is here a fixed sliding window frame, referenced C as a whole adopts a cross-sectional assembly between a cross member 100 receiving and guiding sliders (not shown) and an amount 200.

As illustrated, the cross member 100 and the amount 200 do not adopt the same profile although in accordance with the principles of a cross-section assembly, the end 110 of the cross member 100 is cut in a plane substantially perpendicular to the longitudinal axis of the cross member 100 and that this end 110 is accommodated for assembly by the portion of the end of the profile 210 of the upright 200 turned towards the inside of the frame. This assembly can be achieved directly by means of screws passing through the upright and cooperating for example with alveovis formed in the profile of the crossbar. This assembly can also be achieved by means of an intermediate piece which is fixed to the upright, participates in the positioning of the end of the crossbar, and on which said cross is screwed.

In accordance with the technical problem raised by a cross sectional assembly of two different sections, the Face 210 turned towards the inside of the frame of the upright 200 opens downwards and does not fully mate the profile of the end 110 of the crossbar. In addition, in accordance with the technical problem raised by a cross-section assembly, one of the profiles involved in the assembly partially or fully keeps its open end. According to the invention, a plug 300 solves said technical problem by performing the function of at least a plug at the end of one of the sections by means of a body which has a part 310 penetrating inside said section 200 protruding a bearing surface 320 which partially takes the outer profile of the end 210 of profiled 200 to be plugged and which adopts on its side 330 facing the second profile 100 a complementary shape ensuring at least the continuity of the outer surfaces said second profile 100.

According to another feature, the side 330 facing the end 110 of said second profile 100 has a projection 331 to complete the free volume left between the surface 210 turned towards the inside of the frame of the upright 200 and the outer profile of the end 110 of the cross 100 that it hosts.

According to another particularly advantageous characteristic, said plug 300 is preformed externally with an outgrowth 340 adopting the general profile of an L which, associated with the outer surface of the plug 300 and the sections 100 and 200 which it connects, ensures the continuity of the profile of the grooves 220 and 120 for fixing the joint cover 400 which are preformed externally the upright 200 and the cross member 100. Said seal seals and / or fixing the frame in the wall M as illustrated in the drawing of the figure 7 . The seal cover 400 protects and hides this seal. This continuity facilitates the attachment of said joint cover 400 which can then assume its function on the entire periphery of the frame by seeing its guaranteed fixation.

As illustrated, it is the two outer edges of the end of the profile of the upright 200 which each accommodate a connector plug 300, the central portion being plugged by another cap 500 having fewer features. Thus, the connection between the amount and the cross member of the frame of the invention is made by 3 different plugs.

Thus, as illustrated in the drawings of Figures 5 and 6 , said connecting plugs 300 are manufactured in pairs and adopt a symmetrical configuration with respect to each other due to the symmetry of the profiles of the upright and the cross member assembled as illustrated.

It is understood that the cross-sectional assembly, which has just been described and described above, has been for the purpose of disclosure rather than limitation. Of course, various arrangements, modifications and improvements may be made to the example above, without departing from the scope of the invention, as defined in the claims.
