Description

The invention relates to a carpentry type door or window, comprising at least one leaf lift-sliding resting, through a bearing assembly, on a guide rail that equips a lower rail of a frame, this bearing assembly comprising at least one lifting support carriage comprising, on the one hand, a mounting bracket attached to a lower cross member of the lifting and sliding leaf and, on the other hand, a running carriage secured to the mounting bracket movably in a direction corresponding to the result of a vertical displacement, on the one hand, and sliding horizontal, on the other hand, the leavening-sliding leaf being further equipped with a locking fitting adapted to acting on said at least one lifting support carriage to push the carriage of the latter in a given direction producing the lifting of the leaf during the unlocking command of the latter or in a e reverse direction which results in the collapse of the leaf at the end of closure, said joinery comprising at least one damping device comprising a fastening support (20) reported under the lower crossbar of said at least one leaf lift-sliding. The present invention relates to the field of carpentry of the building and relates, in particular, to doors or windows with sliding sliding door.

In this respect, in this field of joineries of the sliding or sliding door or window type, there are different types of fittings which make it possible to transmit to the leaf a displacement complementary to its sliding in a plane substantially parallel to the frame that 'welcomes.

Thus, in the locking / unlocking phase, this leaf can still move in a direction perpendicular to the plane of the frame, said leaf translation, often having the advantage of a gain in sealing, but also to offer the user has the possibility of giving the leaf a so-called oscillating ventilation position.

Similarly, the lift-sliding door is distinguished in that it is printed in the initial phase of opening and closing, a vertical movement through which it is possible to access a number of advantages. For example, such a solution makes it possible to make flush with the interior and / or exterior floor of the building the rail relative to which the leaf moves and defining the inner cross member of the frame of the joinery. These doors or windows lift-sliding also offer the possibility of relieving the weight of the leaf rolling means when the leaf is in the closed position and lowered in its sleeping frame. In fact, in this lowered position, this fixed frame can take up the weight of the leaf avoiding premature wear of the rolling means.

This type of sliding door or window usually comprises a locking fitting allowing, as the case may be, to lock or unlock the leaf on its fixed frame. But it is also through this lock fitting that it is transmitted to the leaf its displacement, as the case, vertical, in the case of a leaf rising-sliding or perpendicular to the plane of the frame for a door leaf in translation.

Specifically, when unlocking a lifting and sliding leaf for opening the door or window, the user comes to print, through a suitable handle, a command on this lock fitting having the consequence lift the leaf. Therefore, through this command, it comes to oppose the weight that represents this leaf, especially when it is large or accommodates a glazing with high insulation type double or triple glazing, etc ...

These non-negligible constraints printed on the mechanism of this lock fitting have the effect of strongly stress and reduce its service life, regardless of the attention paid to the quality of manufacture.

It should be remembered, in this connection, that the mechanisms of the locking fitting take position in the grooves, provided for this purpose, in carpentry rebate, grooves with standardized dimensions.

It is for example known from the document EP-2535492 , a sliding assembly for a door leaf or sliding door or window comprising support trolleys provided with rolling means coming to equip the lower rail of such a leaver-sliding leaf.

Such a support carriage is broken down into a mounting bracket in rebate of the lower cross member of the leaf, to this mounting bracket is reported a carriage bearing rollers for cooperating with a rail at the lower rail of the sleeping frame.

The carriage is movably mounted on the mounting support in a direction which is the result of a horizontal displacement in the direction of the sliding of the leaf and a displacement in the vertical direction.

It is through a control member, in the form of a toggle joint on which the mechanism of the locking fitting acts, that this displacement of the carriage is obtained with respect to the fixing support, so that it is possible, when unlocking and opening the door or window, to lift the leaf or, as the case may be, to lower the door leaf with respect to the frame at the moment of closing and opening. locking.

The trolleys of each support carriage equipping the lower rail of a leaf are interconnected so that this lifting and lowering operation under the influence of a single control member.

To alleviate somewhat the importance of the weight of the leaf and facilitate the lifting of the latter, especially during the unlocking and opening control, this assembly described in the document EP-2535492 comprises resilient means in the form of a compressed spring, in the state of locking and closing of the leaf. So, by looseness, at least in part, during the lifting maneuver, it is possible for him to assist the movement. Conversely, during closing, this spring is compressed again under the influence of the weight of the leaf falling in the closing phase.

In the solution described in this state of the art, the spring is mounted on a guide rod and is interposed between the carriage on the one hand and a fixed abutment secured directly or indirectly to the lower cross member of the leaf. This fixed stop is similar to a fork engaged on the spring guide rod. Thus, during vertical movements of the carriage, the guide rod, secured to the latter, can move freely and vertically between the two branches of the fork of the fixed stop while maintaining under stress the spring extending along this guide rod between this fixed stop and the trolley.

Between two consecutive support carriages, the spring guide rod is constituted, substantially, by the connecting bar connecting two consecutive carriages.

First of all, it will be noted that the means of assistance referred to in this document EP-2535492 derive from the very design of the lift-and-slide leaf bearing assembly that it describes.

Thus, it is within the framework of a first inventive step that it has been imagined that these assistance and / or damping means are independent of such a rolling bearing assembly for sliding and sliding leaf in the sense that they do not depend on the execution mode chosen for these.

It is therefore in the continuity of the previous inventive step that we imagined a damper device that is able to equip all the leafs-sliding, including those already installed.

As is apparent from the solution described in the document EP-2535492 the assisting spring, although compressed against the fixed stop, shall move relative and slidably in a vertical direction along this fixed stop when raising and lowering the leaf.

Precisely, when the lifting occurs, when this assistance must be the most important, the spring is strongly compressed against this fixed stop and, naturally, tends to oppose such a relative movement relative to the latter.

In short, this design has the effect of opposing, rather than accompanying, the movement of the leaf in its vertical movements relative to the sleeping frame.

It is within the framework of a new inventive step that we have imagined a solution that, rather than opposing the action that must be assisted, perfectly accompanies the movement.

Thus, the action of the elastic return means are exerted substantially in the direction of movement of the carriage relative to the mounting bracket, and this, regardless of the compression state of these elastic return means.

The invention relates to a carpentry type door or window, comprising at least one leaf lift-sliding resting, through a set of bearings, on a guide rail that equips a lower rail of a frame, this bearing assembly comprising at least one lifting support carriage comprising, on the one hand, a mounting bracket attached to a lower cross member of the lifting and sliding leaf, and, on the other hand, a running carriage, rendered secured to the fixing support movably in a direction corresponding to the resultant of a vertical displacement, on the one hand, and horizontal sliding, on the other hand, the leavening-sliding leaf being further equipped with a lock fitting able to act on said at least one lifting support carriage to push the latter's rolling carriage in a given direction producing the lifting of the leaf when the unlocking command of the latter or in a reverse direction from which it results the collapse of the leaf at the end of closing, said joinery comprising at least one damping device comprising a fixing supportrepared under the lower crossbar of said at least one lifting-sliding leaf, characterized in that on this mounting bracket is rotatably mounted a housing, the end of this housing being made integral with this fixing support by means of articulation means with a pivot axis perpendicular to the plane of the leaf, said housing having a longitudinal housing provided with a base on which a first support is supported; end of resilient return means, such as a spring, a second end emerges from said housing and which acts directly or through a pusher on said carriage of said at least one lift support truck.

The advantages which result from the present invention are that, thanks to the particularities of the damper device, the elastic return means with which it is equipped can act in the direction of movement of the carriage relative to its mounting bracket. a support carriage which is provided, usually, a leaver-sliding leaf and this regardless of the state of stress of the elastic return means.

The action of the damper device is optimized thanks to the invention and the mechanical means that compose it, accompany at any time the action it is asked to provide.

Other objects and advantages of the present will appear in the following description relating to an exemplary embodiment.

As wish to represent it Figures 1 and 2 of the attached drawing, the present invention relates to the field of windows or door-type joineries 1, comprising at least one leaf 2 of lift-sliding type on a fixed frame 3.

Thus, this leaf 2 rests, through a bearing assembly 4, on a guide rail 5 that equips the lower rail 6 of the frame 3.

Such a bearing assembly 4 comprises at least one lifting support carriage 7 which, as shown in FIG. figure 5 , comprises, on the one hand, a mounting bracket 8, and, on the other hand, a carriage 9, which can receive one or more rollers.

The fixing support 8 is intended to be attached at the level of the lower cross member 10 of the lift-and-slide leaf 2.

As an exemplary embodiment, this fastening support 8 is in the form of a downwardly open U-section section 11 which, starting from a bottom through which is made the fixing on the lower crosspiece 10 of the leaf 2, comprises two parallel wings 12 between which the rolling carriage 9 takes position.

It is secured to this mounting bracket 8 movably in a direction 13 which is the result of a vertical displacement, on the one hand, and horizontal, on the other hand, corresponding to the direction of sliding.

As visible in the figure 5 , at the level of the parallel flanges 12 of the U-shaped profile 11 corresponding to the fixing support 8, oblong openings 14 extending in this direction of mobility 13 of the carriage 9 may be formed, which comprise guide pins 15 '. engaging in these oblong openings 14.

Therefore, the carriage 9 is able to move relative to the mounting bracket 8 by displacement of the nipples 15 along these oblong openings 14.

Specifically, the control of displacement of the carriage 9 with respect to the fixing support 8 results from a voluntary action, by the user, on a control member corresponding to the locking fitting 16 equipping the lifting-sliding leaf 2.

Thus, this locking fitting 16 comprises, as is generally the case, a control handle 17 in cooperation with a control mechanism acting through a set of operating rods 18 on at least one lift support carriage. 7 to push the carriage 9 of the latter in a given direction producing the lifting of the leaf 2 during the unlocking command of the latter or in a reverse direction from which the collapse of the leaf 2 at the end of closing .

If this lock fitting 16 can, through suitable sets of operating rods 18, act independently on each of the lifting support carriages 7, in an advantageous embodiment, the trolleys 9 of each of these lift support carriages. 7 are united with one another, so that the action on one of them is passed on to the others.

A damping device 19 for application to this type of leaf lift-sliding, can assist the maneuver consisting in lifting the leaf 2 in the initial phase of unlocking the door or window 1 and, in particular, recover the resulting energy the collapse of the leaf 2 during locking to be able to restore it and assist a new maneuver for unlocking and lifting this leaf lift-and-slide 2.

Essentially, such a damper device 19 comprises a fixing support 20 through which it can be attached under the lower rail 10 of a leavening-sliding leaf 2.

From this fixing support 20 is made integral a housing 21 forming a housing with elastic return means 22, preferably in the form of a helical spring 23 emerging from the housing 21, in particular through a pusher 24.

More specifically, in the housing 21 is defined a longitudinal housing 25 having, at one end 26, a bottom 27 on which bears a first end 28 of the spring 23. At its opposite end 29, the longitudinal housing 25 is opening where emerges the second end 30 of the spring 23. Preferably this second end 30 of the spring emerges at this end 29 of the housing 25 through a pusher 24. Thus, by pushing on this second end 30 of the spring 23, this it can be compressed in the longitudinal housing 25 of the housing 21 or, on the contrary, by releasing this thrust action, it can relax by repelling an element on which it rests, in particular through said pusher 24.

As will be described further, in its application to a leaf lift-sliding 2, this second end 30 of the spring 23 is provided to act on the carriage 9.

As visible on different Figures 3 to 5 this second end 30 of the spring 23 emerges from the longitudinal housing 25 through a pusher 24, which is preferably slidably mounted on the housing 21, at the end 29 of the housing 25.

Advantageously, the stop means 31 limit the travel stroke 32 of the pusher 24 to this end 29 of the longitudinal housing 25 corresponding to the housing 21.

Substantially, these stop means 31 may be in the form of an oblong slot 33 formed at the pusher 24 in the direction of movement of the latter relative to the housing 21. This oblong slot 31 is also traversed by a retaining pin 34 maintained, by its ends, by the walls of the housing 21. Obviously a reverse construction is possible and within the reach of the skilled person.

Advantageously, the damper device comprises means for adjusting the prestressing of the elastic return means 22 in the housing 21.

According to an exemplary embodiment of these adjustment means, the bottom 27 at the end 26 of the longitudinal housing 25, bottom 27 on which bears the spring 23, is movably mounted in the housing 25. On the bottom 27 act means adjustment device 35, for example in the form of a screw, for modulating the positioning of this bottom 27 inside the longitudinal housing 25 and, thus, to intervene on this preload of the spring 23.

In particular, according to the invention, the housing 21 is secured at one of its ends by means of hinge means 37.

Preferably, these articulation means 37 are defined with a pivot axis 38 perpendicular to the direction 39 of action of the elastic return means 22. In its application to a leaf 2, this pivot axis 38 extends substantially horizontally, perpendicularly to the plane of the leaf 2 and therefore, perpendicular to the direction of the sliding of the latter.

In this way, this direction of action 39 of the elastic return means 22 can fit freely, by rotation of the housing 21 around the pivot axis 38, to the vertical positioning of the carriage 9 relative to its support. 8. It is precisely on the trolley 9 that the action of the damper device 19, more particularly the spring 23, including the pusher 24 which equips it.

Note that this action of the spring 23, more particularly the pusher 24 on a carriage 9 can intervene through connection means 40 adapted to the latter.

By way of example, such connection means 40 may be in the form of an end piece 41 that can be engaged on an end 42 of such a carriage 9, this end piece 41 cooperating, itself, with the pusher 24 advantageously through articulation means 43 with a pivot axis 44 parallel to the pivot axis 38 of the housing 21 on the fixing support 20.

Insofar as the damping device 19 according to the invention can come to equip a leaf lift-sliding 2 not provided with original means of assistance to its maneuver, it may be interesting, to facilitate assembly, to ensure the retention of the spring 23 in prestressed position in the housing 24. This results in a maintenance of the pusher 24 in a retracted position, that is to say, pushed towards the housing 21, in the end 29 of the longitudinal housing 25.

For this purpose, the damping device 19 may be provided with locking means 45 of the pusher 24 relative to the housing 21, in particular in the retracted preloading position of the elastic return means 22.

In the exemplary embodiment illustrated on the Figures 3 to 5 , these locking means 45 are in the form of a locking screw 46 cooperating with a thread adapted in the housing 21. Thus, by clamping, this screw 46 can come to block the pusher 24 in a given position in the longitudinal housing 25 at the end 29 of the latter.

This blocking position is more particularly illustrated in the figure 4 attached drawings. Note also that in this locking position, the screw 46 can engage in a hole provided for this purpose in the pusher 24 and thus secure this prestressing position of the spring 23.

It should also be noted that Figures 3 and 4 illustrate the damper device 19 in the folded position relative to that occupied once mounted on the lower rail of the leaf 2, as visible on the figure 5 . This locking screw 46 preferably equips the housing 21 at the level of the opposite face of the fixing support 20 so as to remain accessible and facilitate its release after mounting the damper device on the leaf 2.

The advantages of the present invention consist in a perfect efficiency of the damper device in its application to a leavening-sliding leaf. In addition, such a damper device can come equipped leaves that are currently lacking any means of assistance to the lifting maneuver, advantageous assistance to avoid excessive stresses on the locking fitting and to facilitate the user handling of such a leaver-sliding leaf.
