The FIG. 1 shows a sectional view of a cabinet (10) with a body (20) and with a sliding door unit (90). The body (20) comprises a ceiling part (21) and a wall part (22) adjacent thereto. On the ceiling part (21) a guide rail (23) is arranged. In the exemplary embodiment, the guide rail (23) has a mounting flange (24) arranged parallel to the ceiling part (21), which has a reinforcing fold (25) oriented toward the sliding door unit (90), cf. also the Figures 2 and 4 ,

A vertically aligned connecting portion (26) of the guide rails (23) is arranged parallel to the sliding door leaf (91) of the sliding door unit (90) and connects the reinforcing fold (25) with a e.g. double track roller bed (27). The length of the guide rail (23) and the roller running bed (27) corresponds for example to twice the length of the sliding door leaf (91).

At the interior (15) of the cabinet (10) facing inside of the guide rail (23) is a support member (31) is arranged. This is for example a cross-sectionally L-shaped sheet metal or plastic part, which is screwed to the guide rail (23). The support member (31) may also be welded or glued to the guide rail (23). The length of the example 1.25 millimeters thick support member (31) is e.g. 260 millimeters. The length of the vertical leg (32) connected to the connecting portion (25) is e.g. 15 millimeters. The cantilevered horizontal leg (33) of the elbow (31) is 40 millimeters wide in the embodiment. It is also conceivable to integrate the supporting part (31) in the guide rail (23). In the exemplary embodiment, the guide rail (23) with the support part (31) is part of a sliding door fitting unit (30).

The horizontal leg (33) of the in FIG. 5 as an item shown plastic elbow (31) has a keyhole opening (34) and a Einschwenkausnehmung (41). The keyhole opening (34) has in plan view the shape of a longitudinal direction of the support member (31) formed rectangle, the central portion is circular. In one embodiment of the support member (31) as a sheet metal part, the keyhole opening (34) may be punched out, for example. The diameter of the cylinder (38) corresponds for example half the length of a beard opening (37) forming rectangle. The width of the rectangle is one third of its length. It is also conceivable to form the beard opening (37) only on one side on the cylinder (38) penetrating the supporting part. The beard opening (37) can also have the shape of a triangle, a semi-ellipse, a Poygonabschnitts, etc. The beard opening (37) can - in the in the FIG. 5 illustrated plane of the horizontal leg (33) - have any direction to the adjacent cylinder (38). The keyhole opening (34) can also be slotted on the longitudinal edge (42) of the horizontal leg (33) adjacent.

The central axis of the cylinder (38) is a central axis (36) of the keyhole opening (34). This central axis (36) is aligned in the embodiment normal to the bottom (35) of the horizontal leg (33) of the support member (31).

The Einschwenkausnehmung (41) adjacent to the free longitudinal edge (42) of the horizontal leg (33). The finger-like recess (41) is arranged on a circular arc portion about the central axis (36). The lowest point of the Einschwenkausnehmung (41) is, for example, on a parallel to the longitudinal edge (42), which affects the projected into a plane cylinder (38) on the longitudinal edge (42) facing away. The width of the Einschwenkausnehmung (41) corresponds to the diameter of the projected circle (38).

The Einschwenkausnehmung (41) has a locking element (43) in the embodiment. This is an elastically deformable hook (43) which projects in the direction of the inner end (44) of the Einschwenkausnehmung (41) in this. The distance of the connection of the barb (43) from the inner end (44) of the Einschwenkausnehmung (41) corresponds for example to the diameter of the cylinder (38). This connection can be designed as a film hinge. In one embodiment of the support member (31) made of metal, the latching element (43) may comprise, for example, a spring-loaded pivot lever. The locking element (43) is thus at least partially elastically deformable. It is also conceivable to arrange two locking elements (43) or a self-closing locking bolt on the Einschwenkausnehmung (41).

The support member (31) carries a combined acceleration and deceleration device (50). This is another part of the sliding door fitting unit (30). The acceleration and deceleration device (50) comprises a housing (51) in which, for example, parallel to one another, for example, a pneumatic cylinder-piston unit and a spring are arranged. The spring may for example be a deflected tension spring. The piston rod of, for example, sections defined cylinder-piston unit and a free end of the tension spring are connected in the exemplary embodiment of a driving element (52). The carrier element (52) projecting fork-shaped out of the housing (51) is displaceable in the housing (51) between a force-locked and / or positively secured parking position and an end position. In the exemplary embodiment, the piston of the cylinder-piston unit is retracted when the carrier element (52) is in the tilted parking position and the spring is loaded. In the example in the FIG. 3 shown end position of the driving element (52), the piston rod is extended and the spring relieved.

The example, two-piece housing (51) carries on its upper shell (53) has a key pin (61) and a Einschwenkzapfen (71). The two pins (61, 71) are secured to the housing (51), for example by means of screws, adhesively bonded, etc. Their transverse direction (68, 78) is aligned, for example, normal to the longitudinal direction (11) of the cabinet (10), cf. FIG. 2 ,

The in the FIGS. 6 and 7 illustrated key pin (61) comprises a base part (62), a Durchdringstab (63) and a latch (64). The at least approximately cuboid-shaped base part (62) has rounded corners and carries on its underside (65) a centering truncated cone (66). The conical slope corresponds for example to the slope of the countersink of a mounting hole of the housing (51). A through hole (67) for receiving a fastening screw penetrates the base part (62) and the centering truncated cone (66).

For example, by two bore diameter of the through hole (67) offset to this, the cylindrical Durchdringstab (63) is arranged. Its diameter is for example two tenths of a millimeter smaller than the diameter of the circle (38). He is in the exemplary embodiment by five hundredths of a millimeter higher than the thickness of the horizontal leg (33) of the support member (31).

On the Durchdringstab (63) sits the latch (64). Its longitudinal direction is arranged normal to the height direction of the piercing rod (63). With the transverse direction (68) of the key pin (61) it closes in a plan view, see. FIG. 3 , an angle of 45 degrees. This angle can be, for example, between 5 degrees and 90 degrees. The minimum angle results from the arc of the sine of the ratio of the distance of the central axis (36) from the longitudinal edge (42) and the distance of the mounting holes of the housing (51). The maximum angle corresponds to the circle number n, reduced by this value. The distance between the mounting holes of the housing (51) corresponds to the distance between the center line of the Einschwenkausnehmung (41) and the central axis (36). The length and the width of the bar (64) is, for example, 90% of the corresponding values of the beard opening (37).

The FIGS. 8 and 9 show the Einschwenkzapfen (71) in a dimetric view and in a longitudinal section. The Einschwenkzapfen (71) comprises a base part (72), for example, including a centering truncated cone (76) and a through hole (77) has the same outer dimensions as the base part (62) of the key pin (61).

On the base part (72) sits a e.g. block-shaped guide block (73) whose length in the transverse direction (78) of Einschwenkzapfens, for example, one and a half times the width. The width of the guide block (73) is for example equal to the diameter of the Durchdringstabes (63). The guide block (73) can also have a circular arc section-shaped cross section, a circular cross section, etc. in plan view. The height of the guide block (73) corresponds to the height of the Durchdringstabes (63). The e.g. vertical edges of the guide block (73) may be formed at right angles.

The guide block (73) carries a cover plate (74). This covers the guide block-side half of the base part (72). The outer dimensions of the cover plate in the longitudinal (11) and transverse (78) correspond in this area to the outer dimensions of the base part (72). On the side facing the through-hole (77), the vertical rear side (75) of the cover plate (74) is flush with the rear side (79) of the guide block.

The heights of, for example, designed as plastic injection molded parts key pin (61) and Einschwenkzapfens (71), for example, 40% of their width in the transverse direction (68, 78).

On the inner side (92) of the sliding door leaf (91) which can be displaced in the longitudinal direction (11) of the cabinet (10), two support roller units (93, 94) are arranged at a distance from one another, cf. FIG. 3 , Each supporting roller unit (93, 94) in the exemplary embodiment comprises a carrying roller (95) and two lowering safeguards (96). The latter are, for example, in the direction of the interior (15) protruding pins, which are arranged below the horizontal axis connecting the roller axes. On the in the closing direction (97) front roller unit (93) also has a driver (98) is arranged. The driver (98) is L-shaped. Its actuating arm (99) protrudes in the direction of the interior (15). Optionally, the driver (98) regardless of the roller unit (93) attached to the sliding door leaf (91), for example, be screwed.

For the final assembly of the cabinet (10) at the customer mounting units are assembled by the manufacturer. For this purpose, for example, the ceiling part (21), the wall part (22) and the sliding door leaf (91) form individual assembly groups. The combined acceleration and deceleration device (50) together with the key pin (61) mounted thereon and the likewise mounted pivot pin (71) forms a mounting unit. Optionally, the key pin (61) and the Einschwenkzapfen (71) to the housing (51) may be formed.

Another mounting unit forms the guide rail (23) together with the mounted thereon, integrally formed or cohesively connected support member (31).

During the final assembly of the cabinet (10), the body (20) is first set up. On the ceiling part (21), the mounting unit of the guide rail (23) and the support member (31) is screwed, for example.

For example, in the next operation, the carrying roller units (93, 94) are fastened together with the optionally integrated catch (98) on the sliding door leaf (91). The sliding door unit (90) thus produced can now - e.g. without further alignment - be attached to the body (20), that the support rollers (95) in the roller bed (27) of the guide rail (23) sit. In the lower door area, the sliding door leaf (91) is supported, for example, on a further guide rail on the body (20).

Now, the mounting unit of the combined acceleration and deceleration device (50) is installed. For this purpose - with the sliding door leaf open (91) - the acceleration and deceleration device (50) obliquely to the longitudinal edge (42) of the horizontal leg (33) attached to the support member (31), so that the Einschwenkzapfen (71) in the interior (15) of the cabinet (10) stands. The latch (64) is passed through the keyhole opening (34) until the base part (62) of the key pin (61) rests against the underside (35) of the horizontal leg (33). The Durchdringstab (63) is now located in the cylinder (38). Now, the assembly unit of the combined acceleration and deceleration device (50) is pivoted about the central axis (36) until the housing (51) is parallel to the longitudinal edge (42) of the horizontal leg (33).

During this pivoting of the latch (64) pivots above the horizontal leg (33) and thus prevented by the rear handle falling out of the combined acceleration and deceleration device (50) from the support member (31). The latch (64) of the mounted, the support member (31) penetrating the key pin (61) in the representation of the FIG. 3 with the beard opening (37) an angle between 30 degrees and 90 degrees.

The Einschwenkzapfen (71) is inserted by means of the pivoting movement in the Einschwenkausnehmung (41). Here, the cover plate (74) is above and the base part (72) below the horizontal leg (33). The latching element (43) is elastically deformed. As soon as the housing (51) is parallel to the longitudinal edge (42) of the support part (31), the latching element (43) assumes its initial shape and engages behind the pivoting pin (71). The Einschwenkzapfen (71) and the support member (31) lock together.

This assembly requires no alignment and no tools. A wrong assembly is excluded because the key pin (61) only in the keyhole opening (34) and the Einschwenkzapfen (71) only in the Einschwenkausnehmung (41) can be mounted. Even for an untrained end customer, the assembly of the cabinet (10) is thus easily and safely feasible.

The acceleration and deceleration device (50) is now captively secured in the cabinet (10). The entrainment element (52) points to the sliding door element (91).

It is also conceivable first to mount the assembly unit of the acceleration and deceleration device (50) and then the sliding door unit (90).

The assembly unit of the combined acceleration and deceleration device (50) can also be mounted from above on a support part of a guide rail (23). A lateral insertion and pivoting of the acceleration and deceleration device (50) is conceivable.

The cabinet (10) can also be designed such that the support part (31) and the combined acceleration and deceleration device (50) are arranged on the sliding door unit (90). The driver (98) is then attached to the body (20). The sliding door fitting unit (30) comprises in this embodiment the optionally preassembled supporting part (31) and the acceleration and deceleration device (50).

After assembly is in the in the Figures 1 - 9 illustrated embodiment, the combined acceleration and deceleration device (50) in the end position. When first closing the sliding door leaf (91), the driver (98) elastically deforms the first bracket (55) of the driving element (52) and abuts against the stop (56). The bracket (55) returns to its original shape, so that the actuating leg (99) of the driver (98) between the stop (56) and the bracket (55) is included.

When opening the sliding door leaf (91), the driver (98) takes the entrainment element (52) in the direction of the parking position. There, the driving element (52) pivots in the force and / or positively locked parking position. In this case, the energy storage is loaded and the piston rod, e.g. retracted.

Once the driving element (52) is in the park position, the sliding door unit (90) relative to the body (20) can be opened further. In this case, the acceleration and deceleration device (50) arranged on the body (20) remains at rest.

When the sliding door unit (90) is closed again, the actuating leg (99) of the driver (98) contacts. before reaching the eg closed end position of the sliding door unit (90) the stop (56) of the driving element (52). The driving element (52) is released from the parking position. The relaxing energy storage of the acceleration and deceleration device (50) has an accelerating effect on the sliding door unit (90) in the direction of the end position. At the same time the piston rod of the cylinder-piston unit is extended. In this case, in a first stroke region, the cylinder-piston unit acts as an air spring, which strongly brakes the sliding door unit (90). In the following stroke range, the cylinder-piston unit acts as a friction damper. In a last stroke range, the retarding effect of the cylinder-piston unit is canceled. In the partial lift of the total lift of the sliding door unit (90) adjacent to the end position, a resultant force acting on the sliding door unit (90) results from the superposition of the acceleration and deceleration forces. The sliding door unit (90) moves slowly and at low speed into the closed end position, for example.

During rapid closing and opening of the sliding door unit (90), tensile or compressive forces oriented in the longitudinal direction (11) act on the acceleration and deceleration device (50). These forces are transmitted via the key pin (61) and the Einschwenkzapfen (71) on the support member (31) and on the body (20). Due to the large cross-sectional areas of Durchdringstabs (63) and the guide block (73) only slight shear stresses occur in the material. In addition, for example, the transitions of the Durchdringstabs (63) and the guide block (73) to the base parts (62, 72) and the latch (64) and the cover plate (74) are formed as transition radii. Thus, there is no danger that the acceleration and deceleration device (50) will break off in the event of a sudden loading of the sliding door unit (90).

To disassemble the acceleration and deceleration device (50), e.g. when the sliding door unit (90) is opened, the latching element (43) is released. The acceleration and deceleration device (50) can now be swung out against its Einschwenkrichtung. Once the latch (64) is e.g. is above the keyhole opening (34), the acceleration and deceleration device (50) can be pulled down, for example. The bolt (64) is thereby passed through the keyhole opening (34).

The FIGS. 10 to 12 show a further variant of a support member (31) and a Einschwenkzapfens (71). The Einschwenkausnehmung (41) of the support member (31) has here on the longitudinal edge (42) adjacent Ausnehmungserweiterung (45), which is bounded by a retaining lug (46). Adjacent to the retaining lug (46) has the Ausnehmungserweiterung (45) has a triangular wedge receptacle (47).

Einschwenkzapfen (71) has in addition to those associated with FIGS. 8 and 9 features described a lateral actuating lever (81) with a locking wedge (82). The elastically deformable actuating lever (81) is arranged in the basic position, for example, in the transverse direction (78) of Einschwenkzapfens (71). The outwardly directed locking wedge (82) has an oblique contact surface (83) and a locking surface (84) oriented normal to the transverse direction (78).

When swinging the acceleration and deceleration device (50) slides the operating lever (81) of Einschwenkzapfens (71) along the retaining lug (46) along. Once the locking wedge (82) contacts the retaining lug (46), the actuating lever (81) is elastically deformed. As soon as the retaining lug (46) sliding along the contact surface (83) reaches the contact surface (83) leaves, the operating lever (81) is relieved. The actuating lever (81) jumps outwards so that the latching surface (84) lies opposite or bears against the retaining lug (46), cf. FIG. 12 , The acceleration and deceleration device (50) is now locked on the support part (31).

In order to release the acceleration and deceleration device (50) from the support part (31), first the actuating lever (81) is pressed against the Einschwenkzapfen (71) at the over the locking wedge (82) projecting end (85). While the actuation lever (81) is e.g. is manually held in this position, the acceleration and deceleration device (50) is swung out. The Einschwenkzapfen (71) comes out of engagement with the support member (31). The further removal takes place as described above.

The support member (31) may have a plurality of Einschwenkausnehmungen (41). Also, the acceleration and deceleration device (50) may include a plurality of pivot pins (71).

Instead of a cabinet (10) or another piece of furniture in the living area, the sliding door fitting unit (30) can also be used on partitions, sliding doors, etc. in buildings, ie in the construction sector.

Combinations of the individual embodiments are conceivable.
