This horizontal head is perforated with orifices 9 on its upper part (FIGS. 3a and 3b) in order to receive fixing means. In addition, the portion A comprises on both sides of the head 8b and at its end juxtaposing the portion B, two pairs of holes 8e facing each other. These holes 8e are intended to cooperate with the pads 10 present on an intermediate post M of the frame C. The portion A further comprises on its end farthest from the space to close EAF, a folding tongue 8d. As will be seen later, this tongue 8d serves to position a profile 2 at the portion A of the rail 8. In addition, it will constitute for the remainder of the description, the point 0 of the adjusting stroke (FIGS. 5a and 5b). The second portion B comprises in addition to the portion A, two flat bases 8c, each connected to the lower end of the trunk 8a, these two flat bases being horizontal and symmetrical with respect to the vertical axis V-V. Thus, the guide rail 8 is wider at the passage of the door of the space to be closed EAF than at the receiving space ER Furthermore, said guide device 1 further comprises a profile 2 slidable with respect to the guide rail 8. According to FIGS. 4a and 4b, the profile has a substantially U-shaped section that is inverted, that is to say that its section has two vertical tabs 2a that connect only at their upper part, so as to form a notch 2b on the upper part of the section 2. The section 2 is also provided with orifices, in particular at the notch 2b, also to receive fixing means . These fixing means correspond for example to a locking screw 11 for fixing the profile 2 on the guide rail 8 via an orifice 2c located at the end of the profile 2 closest to the space to be closed, or the profile 2 comprises two other orifices 2d located on its other end in order to fix a stopper 5 to said profile 2 via screws 6. Consequently, as shown in FIGS. 1 to 4, the profile 2 has a shape suitable for cooperate with the inner face of the guide rail 8, so as to slide therein. Indeed, its shape fits perfectly in the head 8b portions A and B of said rail 8. However, as shown in Figures 5a and 5b, the section 2 is intended to be mainly positioned at the first portion A of said rail 8, only a part of the section 2, in particular that containing the means for fixing said profile 2 on the rail 8, extends on the second portion B, that is to say on the accessible rail portion. located on the passage of the door. In addition, the section 2 has, towards one of its ends, the one which will be closest to the space to be closed EAF, and on each lug 2a, symmetrically with respect to the axis of the section, an oblong hole. 7. This oblong hole 7 is, as will be seen later, intended to cooperate with two pads of the frame C to limit the displacement of said section 2 relative to the guide rail 8. The device 1 also comprises two sliding elements 3 These sliding elements 3 which are intended to be fixed to the panel P are slidable with respect to the guide rail 8. For this, these two sliding elements 3 may each be and as shown in the figures. 6 a and 6b, a sliding carriage 23 or 33. Each of the sliding carriages 23, 33, as illustrated in these figures, comprises a tapered body having two substantially oval main faces, said oval body 29. This body 29 is extended to one of its extremities , by a tapered projecting part. This projecting portion is preferably in the form of a polyhedron and constitutes the first stop of said sliding system. This is why this projecting part will be referred to as stop 20. Each of the carriages 23, 33 also comprises two bearing assemblies 35 each comprising two stepped rollers 21 connected by an axis 22. The two rollers 21 of a bearing assembly 35 are disposed on either side of the oval body 29 and each rolling assembly 35 is disposed at one end of said body 29. Said oval body 29 further comprises a third orifice 31 situated between the first two and directed in a second direction Y, the first direction X being perpendicular to the second direction Y. sliding carriages 23, 33 are intended to be positioned towards the ends of the panel P, so that said panel P does not lean on one side or another. On the other hand, their positioning is independent of the holes 8e of the rail 8 or the oblong holes 7 of the profile 2. In order to fix each of the carriages 23 or 33 to a panel P, these furthermore comprise a connection screw 24. D on the one hand, this screw 24 is able to be inserted then fixed in said third orifice of said oval body 29. On the other hand, this screw, via its screw head of cylindrical shape and of diameter greater than the body of the screw , is adapted to be inserted into a groove on a mounting plate 15, this mounting plate 15 being itself fixed to said panel P.

Said guiding device 1 further comprises a stopper 5 in order to limit the stroke of the carriage 23 abutting against its abutment 20. The stopper 5 is fixed not on the guide rail 8, it is only connected thereto, but on the section 2. For this, the stopper 5 comprises two orifices 27 adapted to receive fastening means such as screw / nut / washer, so as to fix said stopper 5 on the profile 2. More in particular, the stop 5 is fixed on the lower part of the profile 2 and at its end opposite the oblong holes 7. The stopper 5 further comprises, at its end intended to be in contact with the abutment 20 of said element sliding 3, two arms 28.

These arms 28 have their hooked end 28a to block said abutment 20 when it engages in said arms 28 when opening the door while allowing to easily disengage said stopper 5 when a user wants to close the door. Figures 8 and 9 show a chassis C for sliding door comprising, in addition to a guide device 1 as described above, an inner upright MI, an outer upright ME, arranged vertically and connected both at their upper end. at the ends of the guide rail 8. The guide rail 8 thus forms the upper frame of the frame C. The frame C also comprises an intermediate upright M situated between the inner upright MI and the outer upright ME, so that the distance between the uprights is substantially equal to the width of a panel of a door 7. The intermediate upright M consists of two rods M1 and M2 vertically facing each other, separated, and only for laying by spacers ( not shown), so that the door panel P passes between the two rods M1 and M2 during its operation: opening / closing the door. Said rods M1 and M2 are each fixed at their upper end to the guide rail 8 by studs 10 which pass through the holes 8e and 7. As shown in FIGS. 8, 9, the lower guide rail I is a rail only at the level of the reception space ER of the panel P. Thus, this lower guide rail I and the ground situated at the passage of the door of the space to be closed EAF constitute the lower part of the chassis frame C. The chassis C further comprises between the inner upright MI and the intermediate upright M, stiffeners R used to reinforce the frame of said frame. When laying said chassis C, spacing bars are arranged between the intermediate upright M and the outer upright ME, in particular the ends of these bars are snapped into the aforementioned struts and into holes provided for this purpose on the outer upright ME.

The mounting of a sliding door frame comprising said device 1 and the adjustment of said device 1, will now be described. Firstly, in order to mount the door frame C, the first step consists in fixing the stopper 5 on the end of the profile 2 provided for this purpose, that is to say the one, by means of screws 6. opposed to the oblong holes Io 7. The stop 5 is fixed so that its arms 28 are directed towards the inside of the profile 2 and do not project out of it. Then, the profile 2 is inserted into the head 8b of the guide rail 8. Since the rail 8 has at the end of the portion A, a tongue 8d (Figure 1) foldable, the profile, and more particularly its 15 Stopper 5 is positioned and locked at said tongue 8d. Then, there are spacers between the rods M1 and M2 to form the intermediate amount M. The upper end of the rods M1 and M2 arrives at the oblong holes 7 of the profile and at the holes 8e arranged on the guide rail 8 in order to be able to fix the rods M1 and M2 on the rail 8 by means of the studs 10 (FIGS. 2 and 5). Also by means of a latching system or a notches / tongues system, the internal upright MI is fixed to the rail 8. The same is done with the rods M1 and M2 of the intermediate upright M, the lower guide rail I which is fixed between the inner amount MI and the amount M, the stiffeners R and the spacer bars (not shown). The outer amount ME is then fixed by the same system notches / tongues. The frame C is then fixed on another frame (not shown), generally made of metal and which aims to support said frame C. Next, a partition is glued to the stiffeners R, the intermediate amount M and the lower rail I. Finally, the door is inserted in said chassis C via a fixing plate 15, itself connected to the screw head 26 of the carriage 23 or 33, said carriages 23, 33 being connected to and sliding in the rail system 8. 2. These steps will not be more explicit because they are well known to those skilled in the art.

The adjustment of the guiding device 1 will now be explained using FIGS. 5, 8 and 9. Once the panel P has been mounted and inserted in said frame C as indicated above, the door can be adjusted.

If the final recipient of the sliding door wants for example that the door panel is substantially completely hidden in the receiving space ER, that is to say behind the partition, as shown in Figure 8, the stop 5 is positioned at the tongue 8d of the rail 8, that is to say at the point 0 (5a and 5b) by sliding the profile 2 in the rail 8. Finally, the section 2 is fixed on the guide rail 7 by means of a locking screw 11. Thus, the fastening elements of the profile 2 on the rail 8 (locking screw 11) are accessible at the level of the space to be closed EAF, the adjustment can be done even if the panel and the wall are mounted.

If the final recipient wants the handle O of the panel P is apparent to facilitate the opening of the door (Figure 9), it will first be necessary to slide the section 2 to the portion B of the rail 8 so that that the stopper 5 is at a desired distance d. This distance d corresponds to the door width that exceeds the intermediate post M (Figure 9) or the advancement of the stopper 5 on the rail 8 relative to the point 0 (Figure 5a). In this case and as shown in FIGS. 5a and 5b, the adjustment stroke is ensured by the dimension of the oblong holes 7 which allow the sliding of the profile 2 with respect to the rail 8 despite the 3C presence of the studs 10. Thus, the profile assembly 2 / stopper 5 is moved to the desired position. Then, when the desired position is reached, the profile 2 is fixed to the rail 8 by the locking screw 11. Although the invention has been described in connection with a number of particular embodiments, it is obvious that it It is in no way limited and includes all the technical equivalents of the means described and their combinations if they fall within the scope of the invention.
