SLIDING JOINERY DEVICE
FIELD OF APPLICATION OF THE INVENTION The present invention relates to the field of sliding carpentry devices such as sliding windows and patio doors and especially to adaptations to improve the insulation characteristics. DESCRIPTION OF THE PRIOR ART Conventionally, the sliding windows are constituted by leaves or sliding glass panels called opening in a fixed frame called a frame which delimits an opening closed or opened by the sliding of the opening.
Said frame notably accommodates means for supporting and guiding the openings and is constituted by mounting a plurality of profiles connected by strips of a different material in order to ensure a break in the thermal bridge likely to be formed by such carpentry. The frame has a central recess separating in particular the profiles supporting the paths of displacement of the openings, recess which, with the connection zone between the profiles adopts the general shape of a U. This U-shape of the profile of the central recess is adopted by the entire frame. This recess, which is an exchange zone between the profiles of the sleeping frame and between the openings, has been the subject of numerous changes in order to optimize the following functions in particular. The thermal insulation between the frame part in contact with the outside and the frame part in contact with the interior, the mounting of the openings inside the frame, the flow of infiltration water at the lower horizontal portion of the frame. The implementations of these functions can, depending on the part of the dormant concerned, lead to contradictory characteristics. Indeed, the operation of mounting the openings in the frame requires that the opening can enjoy freedom of movement in the upper cross member of the frame to allow a movement of engagement upward of the opening for allow it to be removed from the rails provided for this purpose on the bottom rail. This freedom of movement is particularly given by the dimensions of said recess which must be filled after assembly to provide insulation and to prevent disengagement. The thermal insulation and generally the protection against the external environment (dust, water, etc ...) requires the presence of a barrier or means of filling avoiding the communication between the volumes separated by the openings to insulation purposes. These barriers are conventionally implemented by sealing means capable of coming into contact with the different constituent elements to be separated. However, these barriers are likely to hinder the installation of openings in high cross or their sliding on the lower cross of the frame. Indeed, the ends of the profiles of the openings, cooperate with that of the frame and in particular partially fill the central recess U. Any barrier in the recess of the lower crossbar is likely to hinder the movement of said openings. These different functions to implement depending on the part of the frame concerned have led the designers of such facilities to offer different sealing solutions depending on the part of the frame, which has the consequence of increasing the installation time and making more complex and more expensive the device.
The thermal insulation problems of a sliding carpentry do not reside exclusively in the section - 3 - constituting the sleepers sleepers. For example, the area of contact between the amount of the opening and the amount of the frame, is hardly likely to receive insulation equipment because this part conventionally supports the constituent elements of the locking device of the opening. In addition, the recesses formed in the amounts of the slider and generally in any profile forming the joinery are likely to be better exploited to optimize the insulation. Although solutions exist, their insulating capacity and their mounting principle are likely to be improved. BRIEF DESCRIPTION OF THE INVENTION The applicant has conducted research aimed at optimizing the implementation of these functions. This research has led to the design of a sliding carpentry device meeting the objectives of the invention by proposing not only an insulation solution that can be used on the different parts of the frame and matching, while optimizing , with the aforementioned functions but also an insulation solution for the contact area between the amounts of the frame and sliders and in the equipment of the various profiles forming said joinery. According to the invention, the sliding carpentry device associating a frame with one or more sliding elements is remarkable in that the frame accommodates a thermal insulation profile consisting of at least two interconnected parts, a first part providing support and maintaining in position in the frame and a second part substantially parallel to the bottom of the U and being positioned closer to the ends of the profile of the openings entering the central recess, the connection between the two parts being elastic allowing the movement of the second part towards the first part and its return to position. This feature is particularly advantageous in that it is proposed with a single profile to ensure the insulation of the entire frame. Indeed, the elasticity will allow the freedom of movement necessary for the engagement of the opening in the high cross. Under the action of the profile of the opening, the second part will move closer to the first and allow the passage of said profile. Returning to the starting position not only ensures good insulation after the assembly operation is completed, but also good insulation in the other parts of the frame, such as uprights and crosspieces. Similarly, although the second part of the insulation profile is not intended to come into rest position in contact with the profiles of the openings, the elasticity will prevent the insulation profile is a drag brake if it contact occurs. This insulating profile can cover the entire length of the frame element in which it is integrated. In addition, in accordance with the objectives of the invention, the insulation profile will ensure its function both in the amounts in the sleepers forming the frame. According to a particularly advantageous characteristic, the connection between the first and second parts is formed by two walls. This characteristic contributes to the partitioning of the recess and consequently to the optimization of the thermal barrier role of such a profile.
According to another characteristic, said first portion is constituted by a horizontal wall bearing on the bottom of said U and whose edges form wings tending at a determined angle to approach the branches of the U in which the profile is registered. By adopting this form, the first part also participates in the partitioning of the recess. According to a particularly advantageous characteristic, the connection between the first and second parts of the profile is formed by at least one wall of elastic material. According to a preferred embodiment, the two walls are made of elastic material. According to a particularly advantageous characteristic, said second part essentially consists of a wall substantially parallel to the bottom of said U and whose edges tend to abut the branches of said U. According to other features, the sliding carpentry device is remarkable in that it adopts one or more of the following characteristics: - said connecting walls adopt at least one fold line facilitating the approach of the second part with the bottom of the U, - said second part comprises two outer projections tending to join the ends of the sliding doors in the sleeping frame. said second part and the connecting walls are made of a flexible material adopting a hardness of between 65 and 95 shore A. the first and second parts and the connecting walls are connected because they are produced in a single coextrusion operation . - The first and second parts are PVC. - The U-shaped profile formed by the frame has on its branches, an inner projection whose distance relative to the bottom of the U ensures the maintenance position of the first part by retaining its lateral branches. said thermal insulation profile is fixed on the thermal bridge breaking strip forming part of the U, this fixing is made by clipping, said thermal insulation profile forms a single piece with the rupture bar of thermal bridge forming part of the U. Regarding the insulation of the contact zone between the amounts of the frame and those of the sliding or sliding, (the frame comprising two uprights and two cross members, at least one of the amounts accommodating a locking device), the sliding carpentry device of the invention is remarkable in that at least one amount of the frame is composed of two parts. an aluminum part and a compartmentalized plastic part which covers the aluminum part and which provides projections which, cooperating with the forms of the opening, will create compartments participating in thermal insulation. According to another characteristic, it comprises at least one striker constituting one of the elements of the locking device which is screwed onto the frame through the plastic part so as to ensure the attachment of the plastic part and that of the striker in the part aluminum. Thus, although welcomed by the PVC part, the strike is fixed to the strongest part of the amount. With regard to the insulation of the recesses formed inside the profiles and in particular inside the amounts of the sliding, the sliding woodworking device of the invention is remarkable in that it comprises one or more partitioning profiles positioned in the recesses present in the profiles of the joinery and which adopt a geometry, ensuring in association with the inner surfaces of the profiles constituting in particular the sliding frame the partitioning into several compartments of the recess defined in said profiles. The basic concepts of the invention having been described above in their most basic form, other details and characteristics will emerge more clearly on reading the description which follows and with reference to the appended drawings, As a non-limiting example, an embodiment of a sliding carpentry device according to the invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 3 is a view of a cross section of the profiles forming the upper part of the joinery in a position illustrating the implementation of the sliding frame, FIG. a cross section of the contact zone between the amount of the opening and the amount of the frame supporting the elements constituting the locking of the opening, FIG. 5 is a view of a cross-section of the sections forming the lower parts and superior of another embodiment of the sliding carpentry. DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawing of Figure 1 shows a carpentry frame ensuring the control of the opening of a window or a French window and composed of a frame 100 in which slide one or more frames sliding windows 200 to move the window from a closed position to an open position and vice versa. The lower cross member 110 of the fixed frame 100 comprises slides 111 on which the sliders 200 move in translation. The drawing of FIG. 2 shows a cross section of the sections forming the upper part of the joinery of FIG. 1. This upper part comprises an upper cross-member 120 of the fixed frame 100 with which the upper cross-members of the sliding frames 200 cooperate. This cross-piece 120 is broken down into two parts 300 and 400 connected by break-off bars 510 and 520. thermal bridge. These two parts 300 and 400 have projections 310 and 410 in the vertical plane and directed towards the center of the frame. These projections are those which, on the lower cross member of the fixed frame 100, support the slides 111 on which the sliding frames 200 move. According to the preferred embodiment illustrated, this crosspiece 120 and generally the frame 100 adopt a symmetrical structure in a vertical plane passing through the middle of the bars 510 and 520. These vertical projections 310 and 410 towards the inside of the frame associated with the connection zone between the two parts form a recess 600 adopting a U-shaped profile. is partially filled by the branches of the cross members 210 forming the upper parts of the sliding frames 200. According to the preferred embodiment, the sections constituting the upper cross members of the sliding frames adopt a U-shaped profile whose branches are arranged on both sides. other projections 310 and 410 formed by the profiles 300 and 400 of the frame 100. Thus, one of the bran said U comes to be positioned between the two projections and partially fills the recess 600. In accordance with the invention, an insulating profile 700 is inserted into this recess 600. This insulating profile 700 consists of a first part rigid 710 participating in its positioning and its holding in position inside the U-shaped profile and a second flexible portion 720 to fill the recess formed by said U and tending to join the ends of the branches of the profiles 10 15 Upper cross members of the sliding frames. This second portion 720 is substantially parallel to the bottom of the U. As illustrated in the drawing of Figure 3, the insulation profile 700 is remarkable in that the connection between the two parts 710 and 720 is elastic and allows the approximation of these last allowing thus the operation of engagement of the openings in the frame during their installation. Similarly, this elasticity allows the return to position of the second part. According to the invention, two walls 721 and 722 provide the connection between the first and second parts. In addition, the first portion 710 consists of a flat portion substantially parallel to the bottom of the U and two lateral branches 711 and 712 tending to flare to come close to the two branches of the U formed by the frame 100. According to a characteristic particularly advantageous, the two connecting walls 721 and 722 adopt a fold line L facilitating the approximation of the two parts 710 and 720 of the section 700, approximation illustrated in Figure 3 by the arrow F1. As illustrated, the second portion 720 has the shape of a convex arch whose flanges 723 and 724 tend to join the branches of the U. The two lateral branches 711 and 712 of the first part 710 positioned at the bottom of the U associated with the two walls link 721 and 722 with the second portion 720 whose edges adjoin the branches of the U implements a partition allowing the creation of five compartments C in the U-shaped recess which optimizes the thermal insulation function of this section 700. The face of the second portion 720 facing the bottom of the U is connected to the two connecting walls 721 and 722. The opposite face has two external projections 725 and 726 tending to join the ends - 211 - of the cross 210 of the opening 200 sliding in the frame 100 and partially filling the U-shaped recess. This feature has the advantage of reducing to a linear support the possible contact which could have r place between the second part 720 and the opening. According to a preferred embodiment, said second portion and the two connecting walls are made of a flexible material adopting a hardness of between 65 and 95 shore A. Such hardness associated with a suitable profile thickness on the one hand, and fold lines and connection points judiciously positioned on the other hand, allows to achieve the desired elasticity for the insulation profile of the invention. According to a particularly advantageous embodiment, the first rigid part and the second flexible part as well as the connecting walls are linked because they are produced in one and the same coextrusion operation. Thus not only the insulation profile of the invention can be positioned in all parts of the frame, but it is also realized in one and the same manufacturing operation. The carpentry device of the invention offers a gain in both simplicity of installation and cost of manufacture. According to a preferred embodiment, the rigid portion and the flexible portion are made of PVC. According to another preferred embodiment, the profiles are made of aluminum. In order to facilitate said installation operation, the U-shaped recess formed by the frame 100 has, on its branches 310 and 410, an internal projection 311 and 411 whose distance relative to the bottom of the U ensures the holding in position of the first part 710 by retaining its lateral branches 711 and 712. Thus, during installation, these branches 711 and 712 will retract to allow the insertion of the profile 700 into the bottom of the U and then deploy to keep it in position. being in abutment against said projections thus forming a "clipping" type connection. According to a non-illustrated embodiment, said thermal insulation profile is fixed on the thermal break bar forming a portion of the U. This attachment can be made by clipping. According to another embodiment not illustrated, said thermal insulation profile forms one and the same piece with the thermal break bar forming a portion of the U. According to a particularly advantageous feature not shown, the good flow of water arriving in this area is ensured by notches of 5x60 mm made every 200 mm in said profile. As illustrated, in the drawing of Figure 4, the sliding woodworking device of the invention is remarkable in that it comprises at least one amount 130 of frame 100 consisting of two parts: an aluminum part 131 and a compartmentalized part 132 made of PVC (or any other plastic material) which covers the aluminum part 131 and which proposes projections which, cooperating with the shapes of the amount 220 of the opening 200, will create compartments C 'participating in the thermal insulation . According to another characteristic, a keeper 800 constituting one of the elements of the locking device is screwed onto the frame 130 through the PVC portion 132 so as to ensure the attachment of the PVC portion 132 and allow the proper attachment of the latch 800 in the aluminum portion 131. Thus, although accommodated by the PVC portion 132, the striker 800 is attached to the strongest portion of the upright 131. As illustrated, the aluminum portion 131 is broken down into at least two linked sections. by means of thermal bridge bars 133 having internal projections 134 disposed perpendicular to the planes defined by the webs to create further compartments C ". partition 900 of the recesses 212 present in particular in the cross 210 of the sliders 200. This partitioning profile 900 adopts a U shape of dimension less than the volume of the évi 212 of the section 210 which receives it and whose upper and lower ends of the legs serve as a base for fins 910 extending angularly (here substantially at 45 degrees) to come into contact with the inner surfaces of said cross section 210. The presence of this partition profile 900 allows the creation, in cooperation with the other elements of the profile of the cross member 210, four compartments C3. This partitioning profile is preferably made of plastic material and in particular PVC. The choice of a plastic material for the partition profile and / or the thickness of said profile makes it possible, because of the use of an open profile (a U from which extends at 45 degrees four fins), exploit the elasticity of the profile to facilitate its mounting and its position in the recess it compartmentalizes. It is understood that the sliding carpentry device, which has just been described above and shown, 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. For example, for reasons of tolerancing, the ribs of the various components of the thermal insulation profile are defined so that they do not come into contact with parts of the joinery. Nevertheless, most parts of the profile can be in contact with the parts of the joinery to which it tends, without preventing their function.
