DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following description of the figures, identical reference numerals are used for components which are the same and/or functionally the same.

The soft closing damper fitting 1 shown in FIGS. 1 and 2 serves for the soft closing of two door leaves 21, 22, which are slidable in two parallel planes in two directions and which at the same time overlap one another, of a double-leaf sliding door 20 (FIGS. 3 and 4) into their end position overlapping one another. The two door leaves 21, 22 are preferably of the same width.

The soft closing damper fitting 1 comprises a soft closing damper 2 (for example an oil damper) which is fastenable to the one internal door leaf 21 for the soft closing of the two door leaves 21, 22 into their overlapping end position, an activator 3 which is fastenable to the other front door leaf 22 and cooperates with the soft closing damper 2, and as a mounting aid for fastening the soft closing damper 2 to the internal door leaf 21, a Z-shaped profiled sheet 4 with a central leg 4a for abutting flat against the rear face of the internal door leaf 22 and with two outer legs 4b angled in each case by 90° in opposing directions. The soft closing damper 2 has in the known manner a follower 5 which cooperates with the activator 3 and which is displaceably guided between a retracted end position and a tilted released position shown in each case in FIGS. 1a, 1b, and may be used for closing to the left (FIG. 1a) or to the right (FIG. 1b) by a laterally reversed arrangement.

For fastening the soft closing damper 2 for left-hand closing, the central leg 4a of the Z-shaped profiled sheet 4 has first fastening holes 6a and a first marking 7a for its fastening position on the internal door leaf 21 and, for fastening the soft closing damper 2 for right-hand closing, said central leg has second fastening holes 6b and a second marking 7b for its fastening position on the internal door leaf 21. The first fastening holes 6a are spaced apart from the second fastening holes 6b and the first marking 7a is spaced apart from the second marking 7b in each case by the same distance A in the longitudinal direction of the profile. In this case, the first fastening holes 6a are located in the one half of the central leg 4a and the second fastening holes 6b are arranged in the other half of the central leg, and namely such that the first fastening holes 6a are arranged for the abutment of the soft closing damper 2 to the one outer leg 4b and the second fastening holes 6b are arranged for the abutment of the soft closing damper 2 on the other outer leg 4b. The central leg 4a is configured in the shape of a parallelogram, and the two outer legs 4b are offset relative to one another by the distance A in the longitudinal direction of the profile. For reasons of the finger protection described in more detail below, the distance A is at least 15 mm. The markings in each case are configured as a continuous transverse slot 7a, 7b extending in the central leg 4a and in one of the outer legs 5b, said transverse slot in turn intersecting a longitudinal slot 8a, 8b extending in the central leg 4a. In each case, a longitudinal scale 9a, 9b in centimetres is assigned to the longitudinal slots 8a, 8b, which indicates the respective (+/−) spacing from the point of intersection (“0” point) of the transverse and longitudinal slots 7a, 8a and/or 7b, 8b. Instead of the slot marking shown, the Z-shaped profiled sheet 4 may also have a nose or notch as the marking.

An activator bracket 10 made of sheet metal has a fastening leg 11 for fastening to the rear face of the front door leaf 22 and a free end which is angled to the front on the fastening leg 11 by 180° and which forms the activator 3. At the top, two tabs 12 are angled to the rear by 90° on the fastening leg 11. Moreover, the fastening leg 11 is provided with a marking 13 designed as a vertical slot for its fastening position on the front door leaf 12.

The mounting of the soft closing damper fitting 1 on a sliding door 20 with two door leaves 21, 22 which are slidable in two parallel planes in two directions and which at the same time overlap one another is described hereinafter.

As shown in FIG. 3a a door marking 14 in the form of a vertical line is attached centrally to the rear face of the internal door leaf 21. The Z-shaped profiled sheet 4 is oriented for right-hand or left-hand closing and placed with its upper outer leg 4b onto the upper edge of the internal door leaf 21. Subsequently, the Z-shaped profiled sheet 4 using its upper marking, i.e. in the present case using its transverse slot 7a or its scale 9a, is aligned with this door marking 14 in the longitudinal direction of the profile and the soft closing damper 2 which is placed on the lower outer leg 4b is screwed by means of the aligned Z-shaped profiled sheet 4 to the rear face of the internal door leaf 21, by fastening screws (not shown) being inserted through holes in the soft closing damper 2 and through the fastening holes 6a or 6b and being screwed into the internal door leaf 21.

As shown in FIG. 3b a door marking 15 in the form of a vertical line is attached centrally to the rear face of the front door leaf 22. The activator bracket 10 is placed with its two tabs 12 onto the upper edge of the front door leaf 22, using its marking, i.e. in the present case using its slot 13, aligned with this door marking 15 in the longitudinal direction of the profile and screwed to the rear face of the front door leaf 22.

As shown further in FIGS. 3a, 3b, each door leaf 21, 22 has two running parts 23 and/or 24 having one respective running roller 25.

FIG. 4 shows the soft closing damper fitting 1 mounted on the sliding door 20 as right-hand closing, in the overlapping end position of the two door leaves 21, 22 in which the follower 5 has been retracted by a closing spring counter to the action of a damper from its tilted release position (indicated in dashed lines) into its end position shown in a solid line, and at the same time has entrained the activator 3 together with the front door leaf 22. More specifically, the follower 5 is entrained by the activator 3 out of a retracted first end position, counter to the action of a closing spring (not shown) as far as the second end position (“park position”) releasing the activator 3, in which the follower 5 is tilted and thereby locked. By means of the released activator 3, the follower 5 is released from the second end position and then together with the activator 3 retracted into the first end position.

A double-track running rail 27 is fastened at the top of the door frame and/or (cupboard) body 26 (FIGS. 5a, 5b), the internal door leaf 21 being suspended by means of its two running parts 23 in the front rail track of said running rail, and the front door leaf 22 being suspended by means of its two running parts 24 in the rear rail track of said running rail and in each case being displaceably guided between a closed and an open end position. The running parts 24 of the front door leaf 22 encompass the internal door leaf 21 together with its running parts 23 in the manner of a clamp such that when the door leaves 21, 22 are displaced the running parts 23, 24 do not mutually hinder one another and only abut against one another in the overlapping end position, and are prevented from travelling further over one another. The overlapping end position is thus defined by the mutual abutment of the running parts 23, 24. The two door leaves 21, 22 are shown in their overlapping end position, and namely in FIG. 5a in the case of a finger protection spacing B₁ which is adjusted to be wide, and in FIG. 5b in the case of a finger protection spacing B₂ which is adjusted to be narrow, between the left-hand gripping strips 28, 29 of the two door leaves 21, 22. The finger protection spacing prevents a finger from being able to become trapped between the gripping strips 28, 29 in the overlapping end position. The desired finger protection spacing may be adjusted, for example, using the longitudinal scale 9a, 9b via an arrangement of the Z-shaped profiled sheet 4 on the internal door leaf 21 which is offset relative to the door marking 14, and should be at least 2 cm. In FIG. 4, the Z-shaped profiled sheet 4 is arranged offset relative to the door marking 14 by −1.5 cm from the zero position which corresponds to a finger protection spacing of 2 cm.

FIG. 6 shows a modified height-adjustable activator 3 which is formed by a height-adjustable screw 30 of the activator bracket 10.

The triple leaf sliding door 20, shown FIGS. 7a-7c, comprises two internal door leaves 21 and a front door leaf 22, wherein the soft closing damper 2 of the one internal door leaf 21 is oriented for right-hand closing and the soft closing damper 2 of the other internal door leaf 21 is oriented for left-hand closing, and wherein the activator 3 of the front door leaf 22 cooperates with the soft closing dampers 2 of the two internal door leaves 21. In FIG. 7a, all three door leaves 21, 22 are closed, in FIG. 7b the front door leaf 22 has been slid over the closed left-hand internal door leaf 22 and in FIG. 7c the front door leaf has been slid over the partially open left-hand internal door leaf 22, in each case into the overlapping end position.
