- the sliding door leaf (2) protrudes, for example, with the handle portion of the Schoum- frame (3) out.
- the sliding door leaf (2) closes the door opening (4) of the door frame (3).
- a wall-side door leaf receptacle (6) and a vertical frame part (5) delimit the door opening (4) and the door leaf lift (9) between the open and the closed position of the sliding door leaf (2).
- the overall length of the door frame (3) is thus determined by the length of the sliding door leaf (2) and the Mosblattstub (9).
- the length of the sliding door leaf (2) is in the embodiment 600 millimeters and the Mosblattstub (9) 500 millimeters.
- the door frame (3) in this embodiment comprises a guide channel (8) in which the guide system (10) is arranged.
- the guide system (10) comprises two fixed (11, 12) and one moving guide part (14).
- the fixed guide parts (11, 12) are fastened in the guide channel (8) in this embodiment.
- the relatively movable guide part (15) is arranged on the upper side of the sliding door leaf (2). It is also conceivable to arrange the two guide parts (11, 12) designated here as fixed on the moving sliding door leaf (2). They are then movable relative to a guide channel (8) mounted second guide member (14).
- the fixed guide parts (11, 12) are, for example, two actuating elements (11, 12) arranged at a distance from each other.
- the actuating element (11) shown on the left has a distance of, for example, 190 millimeters from the left end of the guide channel (8), the actuating element shown on the right.
- ment (12) has the same distance from the right end of the guide channel (8).

- the length of each group (16) - in the longitudinal direction of the sliding door leaf (2) - is here 100 millimeters.
- FIG. 4 shows a dimetric representation of eg a pneumatic acceleration and deceleration device (20). It comprises a central cylinder tube (21), on the two end sides of each of which a frame part (151, 161) is arranged. In both frame parts (151, 161), a catch element (111, 131) is in each case longitudinally displaceable away from a parking position (121, 141) in one of the parking positions End position (122, 142) out.
- the entrainment element (131) shown on the right is in the parking position (141), where it is pivoted there, for example, by 15 degrees in the direction of the nearest end face of the acceleration and deceleration device (20).
- the left driving element (111) is in the opposite of the parking position (121) arranged end position (122).
- an energy store (32) is arranged, which connects the two driving elements (111, 131).
- This energy store (32) is for example a tension spring (32).
- the length of the acceleration and deceleration device (20) in this embodiment is 400 millimeters, that is two thirds of the length of the sliding door leaf (2).
- the height of the installed device (20) is for example 15 millimeters.
- the two frame parts (151, 161) in each case consist of two guide parts (152, 153, 162, 163) which are mirror images of each other and which are e.g. are interconnected by means of a clip connection.
- FIGS. 5, 10 and 11 show longitudinal sections of the cylinder tube (21).
- two pistons (61, 81) of a cylinder-piston unit (42) are arranged in the same cylinder (43) by means of a respective piston rods (67, 87) in FIG.
- each piston rod (67, 87) in each case penetrates an end face (46, 47) of the cylinder (43).
- the piston rod head (68, 88) of each piston rod (67, 87) is pivotable on one take-up member at a time. meelement (111, 131) attached, see. Figures 6 - 9.
- the strokes (123, 143) of the Mitnähmemaschine (111, 131) and thus also the piston strokes are in this embodiment, each 68 millimeters.
- the cylinder interior (44) is for example 117 millimeters long and has e.g. constant inner diameter of 13 millimeters.
- the length of the cylinder interior (44) is thus shorter than the sum of the strokes (123, 141) of the driving elements (111, 131).
- the cylinder inner wall (45) can be smooth.
- one or more grooves may be introduced in regions on the inner wall (45) of the cylinder (43). These may e.g. be arranged symmetrically to the central transverse plane of the cylinder (43) and have a length of, for example, 30% of a piston stroke. The width of a groove is then e.g. a millimeter.
- the single piston (61, 81), cf. 5 is, for example, in two parts from a piston rod part (62, 82) facing the associated piston rod seal (51, 52) and one
- Piston head part (63, 83) constructed.
- the piston rod (67, 87) is plugged into the piston bottom part (62, 82) and is e.g. bonded.
- the piston head part (62; 82) is designed in the shape of a cylinder for mounting the piston head part (63; 83).
- a free space (64, 84) is formed in the piston head part (63, 83), into which, for example, when the two piston parts (62, 63, 82, 83) are glued, the air is displaced.
- a sealing element (71, 91) is positively seated with a clamping area (73, 93).
- This is for example cup-shaped. Its length is for example 30% larger than its diameter.
- the diameter in this exemplary embodiment is 95% of the diameter of the cylinder (43).
- the wall thickness of the sealing element (71, 91) tapers from the clamping region (73, 93) to the end of the sealing element (71, 91) facing away from the clamping region (73, 93).
- an inner collar (74, 94) is arranged, which projects into a receiving area (65, 85) with play.
- longitudinal grooves can be arranged on the outer surface of the sealing element 71, 91.
- the sealing element (71, 91) consists, for example, of nitrile butadiene rubber and has, for example, a halogenated surface.
- a further sealing element (72; 92) is seated adjacent to an abutment flange (66; a shaft seal (72; 92). Its inner diameter is larger than the diameter of the receiving area (65; 85) and its outer diameter is at least as large as the smallest inner diameter of the cylinder.
- the annular groove (75, 95) of the sealing ring (61, 81) shown here points in the direction away from the piston rod (67, 87).
- another sealing element e.g. an O-ring
- the other two sealing elements 71, 72, 91, 92 are biased during assembly.
- Both pistons (61, 81) thus carry piston sealing elements (71, 72, 91, 92), which in the process achieve a sealing effect only in one stroke direction, namely when the individual piston (61, 81) retracts into the cylinder (43).
- the device (20) comprises a displacement chamber (101) which is delimited by both pistons (61, 81) and two compensation chambers (102, 103) each of a piston (61, 81) and a cylinder end face (46; 47) are limited.
- the cylinder interior (44) is insulated, for example against the environment (1).
- the cylinder-piston unit (42) can also be designed so that the compensation chambers (102, 103) communicate with the environment (1).
- the piston (61, 81) virtually hermetically separates a displacement (101) from a compensation chamber (102, 103).
- the individual entrainment element (111, 131) engages around the respective piston rod head (68, 88) and is guided in the frame part (151, 161) by means of two guide pin pairs.
- the center line of the piston rod head (68; 88) and the center lines of the guide pin pairs lie here in a common plane.
- the portion of the entrainment element (111, 131) protruding from the frame part (151, 161) has a receiving recess (112, 132) which is separated by two driving surfaces (113, 114, 133, 134) offset in the longitudinal direction and an open surface (115; 135) is limited.
- the two driving surfaces (113, 114, 133, 134) are e.g.
- the individual driving element (111, 131) is elastically deformable with respect to its guide bolts. For example, it can be pressed in during the first assembly in order to insert the actuating element (11, 12).
- the two guiding parts (152, 153, 162, 163) which encompass a driving element (111, 131), have to guide the driving elements.
- they At their end facing away from the cylinder (43), they have curved regions (155, 165) away from the receiving depressions (112, 132).
- the guide pin pair facing away from the cylinder (43) is seated in the curved area (155, 165) of the oblong holes (154, 164).
- the frame parts (151, 161) have a chamfer (156, 166) in the area of the parking position (121, 141) and a depression (157, 167) in an axial stroke area.
- the tension spring (32) - it has, for example, a constant cross section - is held in receiving eyes in both entrainment elements (111, 131). It is also conceivable to use two energy sources (32), which are each attached to a carrier element (111, 131) and, for example, to a frame part (151, 161).
- the energy store (32) is partially charged or relaxed, for example.
- the left piston (61) is in its right end position.
- the right piston (81) which is also in its right end position.
- the two pistons (61, 81) need not touch.
- the displacement space (101), cf. FIG. 10 is compressed to a minimum.
- the right equalization space (103) has reached its minimum volume.
- the left compensation chamber (102) has its maximum volume in the illustrated position, cf. FIG. 10.
- the acceleration and deceleration device (20) approaches the right actuator (12).
- the right-hand actuating element (12) contacts the right-hand entrainment element (131) and pushes it out of the parking position (141) in the direction of the parking position (141st) with the detent being released ) facing away from the end position (142).
- the movement of the sliding door leaf (2) by means of the delay device (41) is delayed.
- the energy store (32) is discharged and pulls the sliding door leaf (2) into its end position, cf. Figures 2 and 9. There it stays standing jerk-free.
- the right driving element (131) is in the parking position (141) facing away from the end position (142), while the left driving element (111) in the parking position (121) is locked.
- the entrainment element (131) pushes the piston (81) to the left during this closing movement by means of the piston rod (87). Even with a slight displacement of the piston (81), the air in the displacement chamber (101) is compressed.
- the sealing ring (92) is pressed radially outward against the cylinder inner wall (45) according to the principle of self-help.
