The front sliding door 3 is in this case supported via two separate carriages 5 each having one roller 6. The rear sliding door 4 is also movable by a carriage 7 each having one roller 8.
The carriage 5 of the front sliding door 3 has a tilted or U-shaped attachment element 9 and is hung on the rear sliding door 4 when both sliding doors 3, 4 overlap. A holder 11 is detachably mounted on each mounting element 9, and the sliding door 3 can be adjusted in the vertical direction with respect to the guide rail 2.

The rear sliding door 4 also comprises a mounting element 10, which is generally plate-shaped, on which a holder 12 is mounted displaceably, in this case the rear sliding door. A vertical adjustment of 4 can also be performed.
The housing 13 of the self-retracting tool is fixed to one holder 11 and is also fixed on the support 14 facing away from the holder 11 and facing the side.

The fitting for the front sliding door 3 will be described in more detail below, with the vertical adjustment and self-retraction tool functionally within the rear sliding door 4 as in the front sliding door 3. Configured accurately.
As shown in FIG. 2, the support 14 is positioned between the two holders 11 of the carriage 5, has a generally U-shaped outline, and avoids a collision with the rear sliding door 4. In this case, one vertical leg of the support 14 is fixed to the rear side of the sliding door 3 on the front side, and the other leg has a protrusion 45 that protrudes horizontally and is formed as a pin. The housing 13 is held displaceably.

  In FIG. 3, the sliding door 3 is shown in an open position, and a rod-shaped stopper 15 disposed next to the roller 6 on the carriage 5 is located away from the end stopper 16. According to FIG. 4, the sliding door 3 is moved to the end position, and the stopper 15 presses against the end stopper 16.

FIG. 5 shows the sliding door 3 in the end position, where the stopper 15 pushes against the end stopper 16. Furthermore, it is recognized that an active body 17 is provided on the underside of the housing 13 of the self-retracting device, which has an upwardly projecting protrusion and is fixed on the guide rail 2 via fixing means 18. The The activator 17 engages a driver 19 movably mounted on the housing 13. For this purpose, a corresponding guide path is formed on the housing 13 and the driver 19 is pretensioned by a spring to move the sliding door 3 in the closing direction. During the opening operation, the driver 19 is tensioned, stored in a tensioned position, and rotated into the end portion before the activator 17 leaves the driver 19. Furthermore, in addition to a spring that pre-tensions the driver 19, one or more linear dampers are provided in the housing 13 of the self-retracting tool, which decelerate the sliding door 3 before reaching the closed position, especially during the closing operation. Is deployed. It is preferred that no tool is required to mount the housing 13 on the holder 11, which is generally U-shaped and has slots 23 that open outwardly in opposing side walls 22 in each case. A rod-like bolt 24 is screwed through the slot 23 and is rotatably mounted on the housing 13 as shown in FIGS. 6A and 6B.
After screwing the bolt 24 through the slot 23, the bolt 24 is rotated approximately 90 ° to secure the self-retractor housing 13 on the holder 11. A corresponding catch or clamp means 25 is provided on the bolt 24 to prevent unintentional opening of the bolt 24.

  In FIG. 6C, the self-retractor housing 13 is attached to the holder 11, and the holder 11 is configured to be adjustable with respect to the attachment element 9. For this purpose, a threaded bolt 30 that can be rotated by a tool is provided, the threaded bolt 30 having two rings 31, a groove is formed between the rings, and the side wall 22 of the holder 11 is partly formed in the groove. Inserted. Accordingly, the threaded bolt 30 cannot be displaced in the axial direction with respect to the holder 11, but an internal screw corresponding to the threaded bolt 30 is formed in the stopper 15, so that the threaded bolt 30 is rotated. By doing so, the horizontal distance dimension between the stopper 15 and the roller 6 is changed.

  Further, a lever 35 rotatably mounted around the horizontal axis is formed around the stopper 15, and the lever engages behind the T-shaped web on the guide rail 2, and the lever provides a suspension protection means. Form. In this case, the lever 35 has an opening 36, through which the stopper 15 is guided, and the functions of the stopper 15 and the suspension protection means 35 are executed in a compact configuration.

  7A to 7C, the rear side of the vertical leg of the mounting element 9 is shown, in which a number of elliptical holes 40 are arranged, the holes being arranged obliquely with respect to the horizontal and vertical directions. The pin 41 fixed on the holder 11 is guided in three elliptical holes 40. Further, the pin 41 passing through the vertical elliptical hole 42 is fixed on the stopper 15. If the distance between the stopper 15 and the roller 6 is adjusted by rotating the threaded sleeve 30, the pin 41 moves along an oblique elliptical hole 40 as shown in FIGS. 7B and 7C. . When the distance between the roller 6 and the stopper 15 increases, the mounting element 9 decreases, and when the distance decreases, the mounting element 9 rises. The adjustment mechanism is configured as shown in FIGS. 3A to 3E of German Offenlegungsschrift 102011050394. In this case, the holder 11 and the stopper 15 always maintain the same height.

  The housing 13 of the self-retracting tool is fixed to the holder 11 on the roller 6 side facing away from the stopper 15. In this case, the housing 13 is formed in a number of portions, and includes a first housing part 55 disposed on the side facing the sliding door 4 and two displaceably attached to the first housing part 55. Housing portions 50 and 51 are provided. For this purpose, a horizontally long slot 52 is formed in the first housing part 55, and a guide element 53 formed in the housing part 51 passes through the slot.

  8A and 8B, the first housing part 55 is shown in the mounting position. The slot-shaped guides 46 arranged obliquely with respect to the horizontal direction are located on the side of the first housing part 55 facing away from the roller 6 and generally have an elliptical hole 40 extending obliquely on the mounting element 9. Have the same slope. If the holder 11 is displaced corresponding to the inclination of the elliptical hole 40 during the adjustment procedure, the first housing part 55 is displaced with respect to the protrusion 45 on the support tool 14, and the first housing part 55 is in the horizontal direction. Displace diagonally upward or downward without leaving. Further, an enlarged opening 47 is formed in the guide 46, and in particular, if the protrusion 45 has a mushroom-shaped outer shape, the protrusion 45 is screwed through the opening.

  FIGS. 9A and 9B show two housing parts 50, 51 that are displaceably mounted on the first housing part 55. A guide element 53 is formed on the housing part 51, which passes through a horizontally elongated slot 52 on the first housing part 55. In this case, a guide path for the driver 19 is formed in the housing parts 50, 51, the guide path has a receiving part 20 that opens downward, and the projection of the active body 17 engages. In this case, the housing parts 50 and 51 are fixed to each other via a clamp mechanism having a rotatable lever 54. As shown in FIGS. 7A and 7B, one of the levers 54 in this case has a pin, which partially passes through a vertical oval hole 42 on the mounting element 9. This prevents the housing parts 50, 51 from moving together with the driver 19 in the longitudinal direction with respect to the mounting element 9. During the adjustment of the holder 11, only the first housing part 55 is moved in the longitudinal direction of the guide rail 2 with respect to the mounting element 9 by means of the threaded bolts 30.

  FIG. 10 again shows the fitting together with the housing as seen from below in an exploded view. It will be understood that the two second housing parts 50, 51 form a unit and a guide path for the driver 19 is formed on the lower side of the unit. In addition, springs and associated one or more dampers are provided in the housing parts 50, 51. The housing parts 50 and 51 are held on the first housing part 55 so as to be displaceable, and the first housing part itself is held on the support 14 so as to be displaceable. The adjustment mechanism ensures that the sliding door 3 is adjusted perpendicular to the guide rail 2 without the risk of the driver 19 being moved relative to the stationary activity 17. This is because the driver 19 does not move longitudinally with the housing parts 50, 51 relative to the mounting element 9 during vertical adjustment.

  In the embodiment shown, elliptical holes 40, 42 are formed in the mounting element 9, through which the pins 41 and the pins on the lever 54 partially penetrate. Of course, it is also possible to arrange corresponding pins on the mounting element 9, which engage the oval holes on the holder, the stopper 15 and the first housing part 55. Furthermore, another guide mechanism is provided to move the housing 13 together with the holder 11 relative to the mounting element 9.

  In the embodiment shown, only one housing 13 of the self-retracting tool is attached to the holder 11. Of course, in each case, it is possible to attach one housing 13 of the self-retracting tool to both holders 11, and the sliding door 3 is in the opposite end position, ie the closed position and the maximum open position. Can be moved correspondingly. Furthermore, in the case of a cabinet, not only one or two sliding doors 3, 4 can be deployed, but more than two sliding doors 3, 4 can be deployed.
