The rail is provided with guiding units to guide tilting of the tail to the door frame in a transversal manner between a top closing position and a lower pre-opening position. The guiding rail has a cylindrical longitudinal foot (13) housed in a longitudinal housing of the door frame in such a manner to be movable in rotation.

Description

The present invention relates to a system for operating a sliding leaf, said seal compression, wherein the leaf is movable in a direction transverse to its sliding direction, between a closed position in which the leaf is supported in a manner waterproof against the frame, and a pre-opening position in which it is spaced apart to allow it to slide in a plane parallel to the plane of the frame. The invention also relates to a door or a sliding leaf window equipped with the operating system.

The system according to the invention applies to all doors or sliding doors of windows or doors, especially in windows. It finds as much application for doors or windows with a sliding leaf, possibly being inserted inside a partition (partitioning) in the open position, as for doors or windows with two sliding leaves. In this case, the leaves can be moved, each in translation in a direction transverse to its direction of sliding, away from one another, that is to say one towards the inside, and the other towards the outside of the room.

Doors or windows comprising a leaf slides relative to a frame, which can be operated in a direction transverse to the direction of sliding to reach a pre-opening position in which the leaf is removed from the frame and able to slide in a plane substantially parallel to the plane of the frame, exist in a conventional manner. The frame defines an opening in the partition, in a generally vertical plane. In the closed position, the leaf is in frontal support against the frame. The sliding leaf carries a peripheral seal, which is then compressed between it and the frame, so as to seal the door. In the pre-opening position, the sliding leaf is removed from the frame, and it can then be moved in translation in a plane substantially parallel to that defined by the frame, so as to allow opening.

In the usual solutions, the pre-opening movement is achieved by oscillating arms in a rocking motion along a horizontal plane. These arms have the axis of rotation of the carriages capable of moving along the frame, generally located at the ends of the bottom rail of the opening.

Such systems have the disadvantages of being bulky, heavy to implement, and to have a cost of manufacturing and installation important.

Furthermore, it has been proposed, for example, in the Japanese patent application JP01151681 , a system for operating a sliding panel, such as a sliding door, following a frame and using a guide rail of the panel which is movable in a direction transverse to the direction of sliding, this rail being located in the upper part of the frame. The panel is suspended from the sliding carriages which move on the rail, this creates a compression closure due to the weight of the panel which is naturally displaced in this direction.

A disadvantage of this system is that it requires mounting elements, including sliding carriages, very resistant to support the weight of the suspended panel.

Another disadvantage is that the suspended panel has a natural tendency to compress the seal, it takes a significant effort to keep it in the open position, released joints, when sliding. In addition, this system promotes frictions of the panel on the joints during sliding.

The present invention aims to provide a system for operating a sliding leaf relative to a frame, and mobile translation in a transverse direction to the frame, which has a reduced manufacturing cost and installation. The invention also aims that the system allows to obtain a clearance of the leaf which is both large enough so that the seal disposed at the periphery of the leaf does not undergo friction during the sliding of the leaf. leaf, but not too important to remain comfortable to implement; it ensures a simple and easy maneuvering of the leaf, at the same time as an optimal guiding of the leaf, and a good control of the compression force of the joint during the reverse closing operation. The invention also aims to provide a solid system, resistant in time, and ensuring a good seal when the leaf is closed.

For this purpose, the invention proposes a system for maneuvering a sliding leaf according to a frame and movable in a direction transverse to the frame, between a closed position in which it bears tightly against the frame and a position of pre-opening in which it is spaced from the frame to allow its sliding parallel to the plane of the frame, such that the leaf rests by means of carriages on a guide rail which is mounted swinging in a lower rail of said frame

The tilting guide rail being arranged on a lower cross member of the frame, the sliding carriages are preferably fixed vis-a-vis under a lower cross member of the sliding leaf.

Since the transversely movable guide rail is situated at the bottom of the system, the invention thus has the advantage that the weight of the leaf is supported by the ground. The sliding carriages can thus be those commonly used for single sliding systems. The system can more easily accept a fairly heavy leaf. In addition, in this system, the weight of the leaf creates an offset of the leaf favorable to the opening, and thus allow to open the leaf without great effort or cause friction of the joints when sliding, unlike previous systems where the Tilting guide rail is located in the upper part of the frame.

The movement of the leaf in the direction transverse to the direction of sliding is therefore associated with the movement of the guide rail fixed on the frame, in this same transverse direction. Once in the pre-open position, the leaf and the rail are operational to allow the sliding of the leaf along the rail. The amplitude of the displacement of the guide rail is advantageously chosen to allow both a deflection of the leaf which is sufficient to completely clear the seal carried by the door leaf against the frame, and which is as low as possible so as not to to intrude too much into the room in which the door or window is mounted. The movement of the leaf can be of the order of one centimeter. Indeed, in the preferred embodiments of the invention, the system is provided to allow the movement of the leaf towards the interior of the room, that is to say towards the user located inside the building. . This is however not at all restrictive of the invention, and it is also possible to envisage within the scope of the invention an outward movement.

According to an advantageous characteristic of the invention, the guide rail is provided with means for its tilting in the transverse direction, between a closed position and an open position, more particularly between a high closing position and a low position of pre-opening. This embodiment is quite advantageous, both from the point of view of the simplicity of assembly, the ease of operation of the sliding leaf in the transverse direction that results, for its positioning in pre-opening or for its closing. This embodiment is not, however, limiting of the invention, and any other means for moving the guide rail in the transverse direction, in particular by translation, between as much within the scope of the present invention.

According to preferred embodiments in industrial practice, the invention furthermore meets the following characteristics, implemented separately or in each of their technically operating combinations.

In preferred embodiments of the invention, the guide rail comprises a longitudinal foot substantially cylindrical, a longitudinal head and a longitudinal blade connecting the foot to the head.

The foot of the rail is housed in a longitudinal housing, for example such as a longitudinal groove of the frame or via a profile inserted into a groove of the frame, so as to be movable in rotation, and to allow the tilting of the head between the closed position and the pre-open position, more particularly between the upper closed position and the lower pre-open position. The head of the rail cooperates with the guide carriages carried by the sliding leaf vis-à-vis the rail.

Preferably according to the invention, the head of the rail comprises at least at its top a portion of rounded shape so that these carriages are free to rotate around the head, and able to slide along this head to cause the sliding of the leaf. In a particular case, the head of the rail is substantially cylindrical.

Preferably the system according to the invention is such that the center of gravity of the rounded portion, in particular substantially cylindrical, of the head of the rail is located further forward, in the direction of pre-opening of the leaf, than the point of foot rotation, when the leaf is in the closed position. This facilitates the fact that the leaf is maintained in a "natural" configuration favorable to its opening, in particular to avoid the friction of the joints during sliding.

It is quite advantageous in the context of the invention to use roller carriages, which can be mounted on the head of the rail, in particular on the rounded part, so as to slide along this head.

According to another particular case of the invention, said guide rail comprises two zones (sealing) longitudinally débcrd, located on either side of its longitudinal axis, to close the housing containing the guide rail and to to prevent elements such as dust, pebbles, from entering the housing of said rail for example during the passage of people or animals, which can interfere with the operation of the system. More particularly these longitudinal zones in overflow are located at the head of the rail, on either side of the longitudinal axis of said head. Details and advantages of these overflow areas will be mentioned in the description of the figures.

In preferred embodiments of the invention, the system comprises means for limiting the tilting of the rail, which consist in particular of an abutment which limits the tilting movement of the rail, in particular of the longitudinal blade connecting the foot to the rail. head of the rail. These limiting means are advantageously placed so as to ensure a tilting of the rail, and thus a clearance of the leaf, the smallest possible, while being sufficient to allow to completely clear the seal which, in the closed position, is compressed between the sliding leaf and the frame to ensure watertightness and airtightness of the door or window.

Preferably, it is intended to control the movement of the leaf in front of the displacement between the closed position and the pre-opening position, from a drive handle leaf in its sliding movement parallel to the frame. This handle is made in a conventional manner, and associated with a cremone driving, via a linkage, bolts that penetrate conventionally in cooperating struts of the frame.

According to an advantageous characteristic of the invention, the system comprises means for controlling the travel of the leaf in the transverse direction, which are arranged on at least one edge of the leaf, and preferably three edges of the leaf excluding the edge. carrying the sliding carriages. In the preferred embodiments of the invention, the carriages being fixed under the lower cross member of the leaf, the control means are in turn associated with the two uprights and the upper cross member.

These control means are preferably actuated from the operating handle of the leaf. This handle acts in control of the travel of the leaf in the transverse direction by means of at least one rod movable in translation along an edge of the leaf. It actuates preferably three rods which are interconnected and which are movable respectively along the edges of the leaf which carry them.

Thus, quite advantageously, it is preferably provided means for controlling the front deflection of the leaf which are arranged on the three edges of the leaf with the exception of the edge carrying the slide carriage. This makes it possible to ensure both a balanced compression of the seal in the closed position, and a facelift and requiring little effort of the movement of movement of the leaf in the transverse direction.

In preferred embodiments of the invention, the system comprises, preferably on an upper cross member of the leaf, at least one, and preferably two, control members of the front deflection of the leaf whose operation is related to the displacement of the leaf. a rod along this cross. The rod is itself controlled, conventionally, by the operating handle of the leaf.

The control members each cooperate advantageously with the upper cross member of the frame, so as to guide the movement of the leaf in the transverse direction.

Each control member is preferably an elongated piece curved in its central portion. This piece is fixed at one end to the upper cross member of the leaf, and it cooperates by a second end portion opposite on the one hand with the movable rod, and on the other hand, by an end pin, with the upper cross member of the frame, such that the translation of the rod along the upper cross member of the leaf causes the displacement of the first end of the part, and therefore the upper crossmember of the leaf which is secured in the direction transverse to the direction of sliding.

The cooperation of the member with the movable rod is effected in particular by inserting a roller carried by the rod in a groove formed for this purpose on the underside of the part, so that the roller is able to move along this groove, under the effect of the translational movement of the rod along the upper cross of the leaf. Because of the curved shape of the room, the path delimited by the groove is inclined with respect to the axis of the upper cross member of the frame.

The cooperation of the body with the upper cross member of the frame is carried out in particular by inserting the end peg of the piece into a longitudinal groove provided for this purpose under the crosspiece, so that the peg is able to move along this groove during the sliding of the leaf, but it can never be released, so that any displacement in the direction transverse to the direction of sliding is prohibited.

Thus, when the movable rod is actuated in translation along the upper cross member of the leaf, the control member is rotated about its end pin blocked in the groove of the cross member of the frame. This movement has the effect of moving its opposite end fixed to the upper rail of the leaf in the direction transverse to the sliding direction, driving the latter, and therefore the entire leaf, with him.

The amplitude of displacement advantageously corresponds with the amplitude of the forward travel of the leaf printed at the lower rail, by means of limitation of tilting of the guide rail.

In preferred embodiments of the invention, the system comprises, on at least one jamb of the leaf, at least one bolt fixed on a movable rod along this amount is cooperating with a Z-shaped striker arranged vis-à-vis opinion on a solid section sliding the leaf. The keeper guides the bolt moving in the transverse direction. Its amplitude also corresponds to that of the travel movement printed at the leaf at the lower and upper rails.

The profile is preferably fixed to the frame at the top and bottom of the window or door, while being able to slide in the frame at the same time as the leaf.

Such an embodiment is preferably applied to the two amounts of the leaf.

Thus, quite advantageously, the operating movement of the handle of the leaf causes, in a conventional manner, the movement of rods along each of the vertical and upper horizontal edges of the leaf. This movement causes organs carried by these rods to move and guide the leaf in a frontal movement movement, with adequate amplitude. These movements of the members automatically cause the tilting of the guide rail in engagement with sliding carriages fixed to the leaf in the lower part of the frame. Once in the pre-opening position, the leaf can be manipulated by the same handle, sliding in the plane parallel to the plane of the frame in which it is located.

Conversely, to close the door or window, the leaf is guided in sliding, always by the same handle, to the pre-opening position, then pushed back. During this movement, the members follow a reverse stroke relative to the frame, which brings the leaf in the closed position, in which the seal is compressed again between him and the frame, sealing the closure.

During sliding, the peripheral seal carried by the leaf is never in contact with the frame. It does not wear out. The system according to the invention has the same advantage when the Peripheral seal is not worn by the leaf, but by the frame.

The system according to the invention is advantageously simple to produce. It is inexpensive to manufacture, because made from conventional elements, and installation, because of its simplicity of assembly. Its installation cost is notably reduced compared to the devices of the existing prior art. It also has good durability of operation, and it significantly reduces the wear of the seals during the sliding of the leaf. It ensures a good control of the compression force of the joint. It is also easy to implement because it requires a reduced effort to move the leaf in the direction transverse to its direction of sliding.

The invention also relates to a door or a sliding leaf window following a frame, which is equipped with the operating system described above.

A door to leaf or sliding door relative to a frame equipped with the operating system according to the invention is shown on the figure 1 . In this figure, only the respective lower crosspieces 1 and 3 of the frame and the leaf 19 have been shown.

The lower cross member 1 of the frame is disposed in its normal position of use, that is to say substantially horizontal. In its rear part, that is to say intended to be disposed towards the outside of the room, left on the figure 1 , it comprises a fin 2, substantially vertical and ending with an inwardly directed flange, which is intended to abut against a peripheral seal 5 carried vis-a-vis the leaf 19.

The leaf 19 comprises a lower cross member 3, which is extended in its rear part by a support bar 4 of the seal 5. The seal 5 ensures the closing seal when the leaf is in frontal support against the frame, and more particularly against the fin 2.

On the lower cross member 3 of the leaf is fixed a glazing panel 6. A seal 7 seals the fastening of the panel 6 to the lower cross member 3.

In its lower part 8, the lower cross member 3 of the leaf is also provided with a longitudinal joint 9, intended to bear against a vertical abutment 10 carried by the lower cross member 1 of the frame, so as to ensure the seal also to this place.

Under the lower rail 3 is fixed a carriage 11 which is conventional in itself, the roller type. Several identical carriages can be fixed under the crossbar 3.

The roller of the sliding carriage 11 engages around the longitudinal head 12 of the sliding guide rail 18 fixed in the lower cross member of the frame 1, so as to be movable along this head and thus to allow the sliding of the leaf 19. The roller of the carriage 11 is thus engaged around the head 12 of the rail, so as to both slide along this head and rotate around it.

The guide rail 18 comprises, in addition to its cylindrical longitudinal head 12, a longitudinal foot 13, also of cylindrical shape. The foot 13 and the head 12 are connected to one another by a longitudinal blade 14, which has a slightly curved shape towards the front face of the leaf and the frame, that is to say towards the inside of the frame. the piece, to the right in the figure. The center of gravity of the cylindrical head is thus further forward, in the direction of the pre-opening, than the point of rotation of the foot, when the leaf is closed.

The foot 13 of the guide rail 18 is disposed in a groove 15 of the lower cross member 1 of the frame. It is kept trapped in this groove by flaps 16 distributed along the groove, so as to be able to pivot inside the groove, but to remain firmly stuck.

A stop 17 is formed on the lower cross member 1 of the frame, just in front of the groove 15 in which is trapped foot 13 of the guide rail. This stop 17 acts as a limiter of the tilting of the rail 18, by pressing against the blade 14 connecting the foot to the head during the tilting of the latter.

As indicated on the figure 2 the abutment 17 comes into contact with the blade 14 at the curved portion thereof. It limits the movement of the leaf in the direction transverse to its direction of sliding. The height and the position of the abutment 17 are chosen, in relation to the configuration of the rail 18, so as to ensure an amplitude of front deflection of the leaf of the order of a few centimeters or even a few millimeters.

On this figure 2 the leaf is seen in the pre-opening position, in which the seals 5 and 9 are both detached from the parts of the frame situated opposite each other. The leaf is then able to slide, by moving the carriage 11 along the head 12 of the guide rail, in a plane substantially parallel to that of the frame, that is to say in a plane perpendicular to that of FIG. . In this sliding movement, the seals 5 and 9 are not damaged.

A leaf equipped with the operating system according to the invention is shown in perspective view on the figure 3 . The elements constituting the control means of the frontal movement associated therewith are shown in exploded view, for the sake of clarity of the figure.

The leaf 19 comprises conventionally, in addition to the lower cross member 3, two vertical uprights 20 and 20 'and an upper cross member 21.

The leaf 19 is equipped with two sliding carriages 11 which are fixed under its crosspiece 3 so as to be integral in its movements.

The control means of the transverse clearance of the leaf 19 are in the form of a linkage arranged along the three edges of the leaf, that is to say the uprights 20 and 20 'and the upper cross member 21.

On an amount 20, is fixed a first control rod of the movement. A control mechanism 22 of this rod, conventional in itself, is actuable by means of a handle which is not shown in the figure for the sake of clarity, which is also conventional in itself, and which is fixed on the amount 20 of the leaf.

The control mechanism 22 actuates the rod 23 in translation along the upright 20. This rod 23 carries rollers 24 forming bolts. The rollers 24 are movable in translation at the same time as the rod 23. They are inserted into cooperating latches disposed vis-a-vis along the amount, as will be described in more detail in the present description. These latches have a Z-shaped, so as to guide the rollers in the direction transverse to the sliding direction of the leaf.

The rod 23 is connected, via a member 25 for transmitting movement in a direction perpendicular to a rod 26 disposed along the upper cross member 21 of the leaf. The connection via the member 25 is made such that when the vertical rod 23 moves in translation along the upright 20 of the leaf, the horizontal rod 26 is brought in translation along the upper cross member 21. The rod 26 is associated with organs of control of the front travel of the leaf, which will be described in more detail hereinafter in the present description.

The rod 26 is itself connected, at an opposite end, via a transmission member of the movement 27 similar to the member 25, to a vertical rod 28 disposed along the upright 20 'of the leaf. The rod 28 is slidable along this amount.

The rod 28 also carries rollers 29, which are integral in translation of the rod, and which fit and move, like the rollers 24, in Z-shaped strikes in a transverse direction of the leaf

This mechanism ensures, by the displacement of the rollers 24 and 29 in the corresponding strikes, and by the implementation of the control members associated with the upper rod 26, the control of the tilting of the leaf in the direction transverse to its direction of sliding. This command is triggered by means of the handle actuating the control mechanism 22.

As shown on the figure 4 , which illustrates the leaf in the pre-opening position, at each of its vertical uprights 20 the leaf is associated, for the control of the deflection of the leaf, to a longitudinal section 56 which extends vertically along the upright 20. In this profile 56 are excavated the Z-shaped latches cooperating with the rollers 24 carried by the rod 23 of the leaf. The profile 56 is held in place at the top and bottom of the window by fixing to the frame. It is secured to the leaf in its sliding movement for opening, in the direction indicated in 60.

In order to ensure tightness in the closed position, the profile is inserted, by a perpendicular rear end branch 58, in a longitudinal groove 59 formed for this purpose in the amount of the frame 55 vis-à-vis. When sliding in the direction 60, the branch 58 emerges from the groove 59 to allow the opening of the door or window.

In its so-called forward part, that is to say directed towards the interior of the part, opposite to the frame 55, the profile also fits into a longitudinal groove 57 formed in the leaf upright 20. When, under the effect of the translation of the rod 23 along the upright 20, the rollers 24 move in the latches cut in the profile 56, the upright 20 moves accordingly laterally relative to the section which remains fixed, of right on the left in the figure. This displacement is allowed by the depth of the groove 57 in which the profile is inserted. The assembly then moves in a sliding manner.

This embodiment of the profile is however not at all restrictive of the invention. It is also possible for example in the context of the invention to fix the profile to the amount of the frame, articulating about an axis disposed along this amount, over its entire height. Thus, the profile carrying the latches is rotatable about this axis, and it is able to fade automatically when the leaf is actuated in sliding. An automatic return system returns it to its initial position, that is to say pressed against the sash amount, when the latter is returned to the pre-opening position.

The control means of the front deflection of the leaf fixed on the upper cross member 21 are shown in more detail on the figure 5 in exploded perspective, and on the figure 6 .

The rod 26, which is movable in translation along the upper cross member 21 of the leaf is disposed under a headrest 30 which is fixed on this cross. Two rollers 31 are integral with the rod 26, preferably arranged in each of its opposite end portions. The rod 26 also comprises, at its opposite longitudinal ends, members 32 for its respective attachment to the transmission members 25 and 27.

The headrest 30 comprises, in its two opposite end portions, longitudinal slots 33. The rollers 31 each fit through one of the lights 33, so as to be able to move in translation inside the light, which remains as for it fixed, during the movement of the rod 26.

A piece 34 is attached to the headrest 30 at each of the opposite end portions thereof. Each piece 34 has an elongated and curved shape in its central portion 35.

At a first end 38, the piece 34 is secured to the fixed headrest 30. It is in particular fixed to the headrest by means of a fixing pin 39.

At a second opposite end portion 36, the piece 34 comprises in the underside 54, vis-à-vis the upper cross member 20 of the leaf, a longitudinal groove dug in its thickness. The roller 31 secured to the rod 26 is disposed inside this groove, able to move in longitudinal translation. Due to the curvature of the piece 34, when all of these elements are assembled to each other, the groove forms a path which is slightly inclined backwards, that is to say toward the frame, relative to the axis of the upper cross-piece of the leaf.

At its end portion 36, the piece 34 also comprises, on its upper face, a roll 37 which is arranged in a longitudinal groove provided for this purpose under the upper cross member of the leaf, so as to be movable in the direction sliding of the leaf, but not in the transverse direction.

The different elements thus assembled are represented on the figure 6 .

In this configuration, when the rod 26 and actuated in translation along the upper cross member 21 of the leaf, the roller 31 moves in the groove formed in the underside This has the effect of printing to the piece i rotational movement, in a horizontal plane, around the roller 37 which is fixed in the frame. This movement has the effect of removing the opposite end 38 of the plan of the frame. This end being fixed to the upper cross member 20 of the leaf, the latter is also automatically spaced from the plane of the frame. The whole leaf then moves in the direction transverse to the direction of sliding, and all the more so that the same movement is printed at its uprights 20 and 20 ', by the simultaneous movements of the rollers 24 and 29. in their respective associated spoils.

All of these movements cause the leaf to tilt, and the guide rail 18, in the direction transverse to the sliding direction of the leaf. Thus, the forward movement of the leaf movement is accompanied by a slight downward movement, due to the tilting of the guide rail. This movement is followed at the level of the control members, both on the amounts and on the upper rail.

It is thus quite simple, from a handle arranged on a jamb of the leaf, to control without effort the movement of the leaf in the transverse direction.

An alternative embodiment of the control means of the frontal deflection of the leaf, arranged in the upper part of the door, are represented on the figure 7 .

It is a rail 42 which has the same length as the upper cross member of the sliding leaf, and which is fixed under the upper cross member of the frame, in a groove of the latter provided for this purpose. Along the rail 42 is disposed a longitudinal plate 61, which is adapted to move in translation along the rail.

On the plate 61 are fixed two pieces 43 in which are hollowed grooves 44 in the shape of Z. These grooves are arranged to be vis-à-vis the upper cross member 21 of the leaf, and more particularly two rollers 31 conventional in themselves, fixed on a rod 26 movable along the crosspiece 21. The rollers 31 are placed inside the corresponding grooves 44. These grooves are oriented so as to guide the rollers 31 in the direction transverse to the direction of sliding of the leaf.

An additional piece 45, pierced with a cavity 46, is fixed on the plate 61 between the two pieces 43. This cavity 46 is intended to receive, when the rail 42 is positioned in its operative configuration on the frame, a pin of drive fixed on the upper cross member 21 of the sliding leaf.

Thus, when the rod 26 and the rollers 31 that it carries are actuated in translation along the upper cross member 21 of the leaf, the rollers move along the grooves 44, thus ensuring the drive leaf in its movement movement. front. Once in this position, when the leaf is slidably actuated, the plate 61 is slidably engaged with it by means of the fixed pin inserted into the cavity 46.

The operating system according to the invention has been described above in the case of a door with a single leaf, coming if necessary, in its open position, fit inside the partition on which the door is mounted.

According to another embodiment of the invention, the operating system can be adapted to a door having two sliding leaves, conventional in themselves.

In this case, as illustrated on the figure 8 , for the vertical uprights 47 and 47 'of the leaves 48 and 48' arranged opposite, an alternative solution ensuring the control of the front deflection of each of the leaves. This solution is represented on the figure 8 .

In this figure, the leaf 48 ', shown at the bottom right of the figure, is in a pre-opening position. Leaf 48, shown at the top left of the figure, is him in the closed position. Both leaves 48 and 48 'are slidable for opening each in the direction respectively 49 and 49', that is to say in which they intersect.

The operating system according to the invention is then configured to ensure that each of the leaves 48, 48 'can be moved in the direction transverse to the direction of sliding. These transverse displacements are carried out in opposite directions, that is to say by moving the leaves away from each other, one towards the inside of the room, the other towards the outside.

According to the invention, each of the leaves 48, 48 'is equipped with an operating system according to the description above on its lower cross member, on its upper cross member, and on its outer amount as opposed to the amounts vis-à-vis -47 and 47 '.

On the amounts facing each other 47, 47 'are fixed rollers 51 and 51' respectively, conventional in themselves, integral with rods 52, 52 'movable in translation along the uprights.

Vertical profiles 50 and 50 'are associated with each of the uprights 47, 47'. These profiles are maintained in the vertical position at the upper part of the leaf. They are in solidarity with the latter in sliding.

On each of the profiles 50 and 50 'is hollowed a Z-shaped keeper groove, cooperating with the roller 51, 51' associated so as to control the movement of the leaf, in the same manner as explained above.

The front movement of each leaf is thus ensured by moving the roller in the strike carried by the associated section.

The profiles 50 and 50 'each further have, at their longitudinal edges facing each other, a return 53, 53'. The returns face each other and provide closure sealing at the area of the uprights 47, 47 '.

On the Figures 9 and 10 is shown a variant of a door to leaf or sliding leaf according to a frame equipped with the operating system according to the invention, the guide rail having sealing areas in overflow. In these figures, only the respective lower crosspieces 1 and 3 of the frame and the leaf 19 have been represented.

On the figure 9 , the lower cross member 1 of the frame is disposed in its normal position of use, that is to say substantially horizontal. In its rear part, that is to say intended to be arranged towards the outside of the room, to the right on the figure 9 , it comprises a profile 70, for example extruded aluminum, comprising a seal 71. This profile 70 is intended to bear against a peripheral seal 72 carried vis-a-vis the leaf 19 and also in compression at the joint 71 with the hubcap 73 carried by the lower cross member 3 of the leaf 19.

The leaf 19 comprises in its front part a seal 74.

The seals 71, 72 and 74 ensure the closing seal when the leaf is in frontal support against the frame, and more particularly against the section 70.

On the lower cross member 3 of the leaf is fixed a glazing panel 6.

The profile 70 comprises a portion 70a in which is housed the guide rail 18, movable in the direction transverse to the sliding. This portion 70a, which is itself housed in a groove 75 of the cross member of the frame, has a shape, height and position adapted to the configuration of the rail 18 and has areas 70b and 70c respectively forming a stop on the side and side. other rail 18 to limit the amplitude of the front travel of said rail 18 to a few millimeters (6-8 millimeters).

The rail 18 also has a longitudinal head 12, of rounded shape at its top, a longitudinal foot 13 of shape rounded, and a longitudinal blade 14 connecting the foot 13 and the head 12 of said rail.

Under the lower cross member 3 of the leaf is fixed a slide carriage 11, which is conventional in itself, the roller type. Several identical carriages can be fixed under the crossbar 3.

The roller of this carriage 11 engages around the longitudinal head 12, at its rounded top, so as to be movable along this head, to thereby allow the sliding of the leaf 19. This also allows the carriage 11 to rotate around this head, to thereby allow the rail 18 to swing in the direction transverse to the sliding.

The longitudinal head 12 comprises two longitudinal zones 12a and 12b, longitudinal and located on either side of the longitudinal axis of this head, which provide a seal at the rail and thus prevent stones and dust enter the housing containing the rail 18 located in the lower part of the cross member 1 of the frame when for example the passage of people or animals. These overflow areas 12a and 12b have a width adapted to that of the housing of the rail 18 so that the housing is closed, the system is in the closed position or in the pre-open position as also shown in FIG. figure 10 relative to this same system in pre-opening position.

The foregoing description clearly explains how the invention achieves the goals it has set for itself. In particular, it provides a system for maneuvering a leaf sliding in a frame and movable in a direction transverse to its direction of sliding, which is simple to use, which ensures a good accuracy of the displacement of the leaf both for its sliding as in the transverse direction, and which has a good durability of operation.

It nevertheless follows from the foregoing that the invention is not limited to the modes of implementation which have been specifically described and shown in the figures and that it extends on the contrary to any variant passing through equivalent means.
