FIG. 1 shows a combined acceleration and deceleration device (10) in a parking position (11). Such a device (10) is used, for example, on a door, for example a sliding door or a drawer, which is moved along a total stroke between an open and a closed end position in both directions, for example manually or motor-driven. In a partial lift of the total lift adjacent to one of the two end positions, the combined acceleration and deceleration device (10) couples with a driver (5) arranged, for example, on a furniture carcass (3). This coupling causes a triggering with the driver (5) coupling driving element (71) of the acceleration and deceleration device (10) from the parking position (11). The acceleration and deceleration direction (10), which is shown in Figure 2 with the housing removed, takes over the control of the door or drawer movement. On the door or on the drawer, for example, an approximately linear acceleration force is applied by a discharging, rechargeable energy store (121), which is superimposed, for example, with a section-wise defined deceleration force counteracting the acceleration force. The Mitnähmeelernent (71) of the acceleration and deceleration device (10) is moved to a parking position (11) facing away from the end position (12), see. Figure 3. The resulting force acting on the door or drawer moves the door or drawer to its end position, where it stops without jerk or stop. When manual or motorized door or the

Drawer from the end position, the entrainment element (71) of the acceleration and deceleration device (10) from the end position (12) in the direction of the parking position (11) is moved. In this case, the energy store (121) is loaded again. As the door or drawer is moved further, the coupling between the driver (5) and the acceleration and deceleration device (10) is released in the parking position (11) of the carrier element (71). The acceleration and deceleration device (10) remains in the parked position (11) until, when the door or drawer moves again in the direction of the end position, the driver (5) is coupled to the carrier element (71).

It is also conceivable, the acceleration and

To arrange delay device (10) on the furniture body (3) and the driver (5) on a door or on a drawer.

The combined acceleration and deceleration device (10) comprises a carrying and guiding device (30) with a cylinder-piston unit (41), the entrainment element (71) and the energy store (121).

FIG. 4 shows a longitudinal section of such a device

Acceleration and deceleration device (10). In the figure 5 a part of the delay device (40) is shown enlarged.

The carrying and guiding device (30) comprises a two-part housing (31) with mutually mirror-symmetrically arranged housing parts (32). The housing (31) comprises a receiving area (33) and a guide area (34). In the receiving area (33), the cylinder-piston unit (41) is held by means of two lugs (35) engaging on the cylinder head part (42). The guide region (34) comprises, for example, two guideways (37) arranged opposite one another. In the exemplary embodiment, these guideways (37) recessed grooves, each having a parallel to the stroke directions (55) of the piston (45) and the piston rod (44) of the cylinder-piston unit (41) oriented portion (38) and one of these adjoining a quarter circle forming bent portion (39). FIG. 12 shows a housing part (32) with a guideway (37). The section (39), which is not parallel to the direction of movement (55), may be straight or curved. In the illustration of Figure 4, the bent portion (39) is directed downwards. The groove width is in the exemplary embodiment three millimeters. Another design of the housing (31) is conceivable. For example, at least one guideway section (38, 39) can be used as a guide (38, 39), e.g. be designed as a body edge.

The cylinder-piston unit (41) comprises a cylinder (46) in which a piston (45) is guided. The cylinder (46) comprises a cylinder jacket (47) with a head part (42) and a cylinder bottom (43) inserted into the cylinder jacket (47). The cylinder jacket (47) and the cylinder bottom (43) are produced, for example, as injection-molded parts made of thermoplastic material, for example polyoxymethylene. The cylinder jacket (47) is here cylindrical on its outer side and has a constriction (48) in the cylinder head area. Its length is for example nine times the outer diameter. The non-cylindrical cylinder inner wall (51) is designed, for example, for demoulding, for example in the form of a truncated cone shell. The smaller cross-sectional area of this truncated cone edge is located on the head part (42) of the cylinder (46), the larger cross-sectional area on the cylinder bottom (43). The slope of this cone is for example 1: 140. The inner wall (51) is optionally polished.

In the cylinder inner wall (51) is for example a

Longitudinal groove (52) arranged whose length is e.g. 70% of the cylinder length is, cf. Figure 5. It ends at the cylinder bottom (43). Their width is e.g. 2% of the larger diameter of the cylinder inner wall (51). Instead of a single groove (52) can also be arranged a plurality of grooves (52) on the inner wall (51). Also, these may be e.g. helically along the inner wall (51) of the cylinder jacket (47).

At the bottom end (49) of the cylinder jacket (47), a further longitudinal groove (53) in the cylinder inner wall (51) may be arranged. Their length is e.g. 15% of the cylinder length. Each of these grooves (52, 53) increases the cross section of the cylinder interior (54).

For insertion of the cylinder bottom (43) has the bottom end (49), for example via a two-stage rotationally symmetrical Notch (56). During assembly of the cylinder bottom (43), the air is displaced out of the region of the outer notch to the outside, while the air from the inner notch in the cylinder interior (54) is displaced. Other embodiments of a hermetic seal are also conceivable.

In the head part (42), in this embodiment, the piston rod lead-through (57) and a e.g. arranged on the head part (42) integrally formed piston rod seal (58). Hereby, the cylinder internal space (54) is sealed against the environment (1).

In the illustrations of FIGS. 4 and 5, the cylinder (46) of the carrying and guiding device (30) has a spring receptacle (59) on its underside. This carries together with a second, on Mitnähmeelement (71) arranged spring receptacle (72) an energy storage device (121), e.g. a spring (121). In the exemplary embodiment, this is a tension spring (121).

The piston (45) carries two piston sealing elements (61) and (62). These delimit, at least in a partial stroke of the insertion movement of the piston (45), a displacement space (65) from a compensation space (66).

Both piston sealing elements (61) and (62) are oriented in the embodiment in the direction of the cylinder bottom (43). The oriented in the direction of the displacement space (65)

Shaft sealing ring (61) rests with its outer sealing lip (63) against the cylinder inner wall (51) at least in the parking position (11) shown in FIG. In the end position (12) shown in FIG. 3, the sealing lip (63) is released from the cylinder inner wall (51). When pressure is applied, the shaft sealing ring (61) engages the second piston sealing element (62), for example a brake collar (62) clamped in the piston (45). The piston rod (44) is the actuating element (44) of the deceleration device (40). It is locked with its piston rod end (67) in a piston rod receptacle (97) with the catch element (71). The piston rod (44) may be rigid or flexible.

The two-part entrainment element (71) shown in FIGS. 1-4 comprises a guide part (81) and a

Securing part (101), which are pivotable relative to each other.

The guide part (81) shown in FIG. 6 comprises a guide area (82) and a stop area (83). In the exemplary embodiment illustrated here, it is constructed asymmetrically with respect to its vertical center longitudinal plane. However, the guide member (81) may be constructed symmetrically to this level. In the exemplary embodiment, the guide region (82) comprises a support web (84) which, on its right side as viewed from the retarding device (40), has a guide pin (85) with an oval cross section. The support web (84) comprises on this side a Querführungs- surface (86), see. Figure 10. The longitudinal direction of the oval is oriented after the mounting of the driving element (71) in the direction of the horizontal portion (38) guide groove (37). The center distance in the longitudinal direction is for example four times the height of the guide pin (85). On the left side of the delay device (40), a guide pin (87) and a receiving and guiding pin (88) are arranged on the carrier web (84). In the exemplary embodiment, its height corresponds to the height of the guide pin (85). The guide pin (87) with an oval cross-section facing the retarding device (40) has half the length of the guide pin (85) lying opposite it. The length of the receiving and guide pin (88) is half the length of Guide pin (87). Both the guide pin (87) and the receiving and guiding pin (88) have a transverse guide surface (91) adjoining the respective guide section (87, 89). The cylindrical receiving portion (92) of the receiving and guide pin (88) has a diameter which is 80% greater than the height of the

Guide pins (85, 87, 89). In the mounted state, the guide pins (85, 87, 89) engage in the guide tracks (37) of the housing (31).

On the support web (84) sits on the support web (84), e.g. formed longitudinal member (93) whose width, for example, 40% greater than the width of the guide member (81) over the

Guide pins (85, 87). The longitudinal member (93) carries an integrated in this stop (94). The height of the driving stop (94) in the exemplary embodiment is 40% of the height of the guide part (81). The wedge-shaped driving stop (94), for example, has a stop surface (95) oriented away from the delay device (40). This stop surface (95) has in the illustration of

Figures 1 - 4 and 6 a transverse groove (96) which has a constant cross-section over its width. The transverse groove (96) forms a form-fitting element (96). When using the combined acceleration and deceleration device (10) surrounds this after contacting partially the driver (5), which has the shape of a cylindrical pin in Figures 1 and 2.

The guide part (81) further comprises a piston rod receptacle (97) facing the retarding device (40). In this is in the assembled state, cf. Figure 4, the piston rod head (67) fixed or detachable. FIG. 7 shows a securing part (101). This has two opposing cylindrical Führungsza fen (102), the spring retainer (72), a bearing ring (103) and a driving stop (104). The width of the securing part (101) and its width via the guide pins (102) in the exemplary embodiment correspond to the corresponding dimensions of the guide part (81).

The spring receptacle (72) of the driving element (71) has a double hook (73), which in the assembled state, see. the

FIGS. 2 and 4, the head (122) of the tension spring (121)

engages behind. The bent in the direction of the end face (74) hook (73) prevents both in the parking position (11) and during the entire stroke of the driving element (71) in

Direction of the end position (12) unhooking of the spring (121).

The inner diameter of the bearing ring (103) of the securing part (101) is larger by a few tenths of a millimeter than the diameter of the receiving portion (92) of the guide part (81). In the assembled state, cf. Figures 2 and 4, the securing part (101) by means of the bearing ring (103) is pivotally mounted on the guide part (81).

The securing part (101) can also be connected to the guide part (81) by means of a film hinge. It is also conceivable to mount the securing part (101) and the guide part (81) on a common bearing pin. Also, a designs of the pivot joint (75) are conceivable. The wedge-shaped in the exemplary embodiment stop member (104) has a in the direction of the delay device (40) facing stop surface (105). In the illustration of Figure 7, the stop surface is flat. The plane of the abutment surface (105) is normal in the embodiment the plane defined by the guide pins (102) and the center line (106) of the bearing ring (103). The intersection line of the two planes lies between the guide pin (102) and the center line (106) of the bearing ring (103).

The stop surface (105) of the securing part (101) - like the stop surface (95) of the guide part (81) - have a transverse groove. These transverse grooves have, for example, identical dimensions.

The two abutment surfaces (95, 105) of a driving element (71) are directed in the representations of Figures 2-4 opposite to each other. Their normal vectors thus show at least after leaving the parking position (11) in opposite directions.

The parting line (76) between the guide part (81) and the securing part (101) is offset in the representation of FIG. 4 with respect to the pivot joint (75) towards the securing part (101). At least that on the Mitnahmeausnehmung (77) of the driving element (71) adjacent, in the figure 4 upper end (78) of the parting line (76) after leaving the parking position (11) lie in a plane normal to that through the guide pin (102) and the center line (106) of the

Swivel joint (75) spanned plane is located. The intersecting line of these planes then either coincides with the center line (106) of the pivot joint (75) or is in

Direction of the security part (101) offset to this. In an arcuate or polygonal configuration of the end (78) of the parting line (76) each point is either on or in

Direction of the securing part (101) offset from said plane by the center line (106) of the pivot joint (75). In the mounted state of the acceleration and deceleration device (10), this is arranged, for example, on a drawer. On the furniture body (3) then the fixed driver (5), for example a cylindrical pin is arranged. When the drawer is open, the acceleration and deceleration device (10), for example, in the parking position (11), see. FIG. 1. The guide part (81) is held completely in the horizontal section (38) of the guide tracks (37). That to

Guide part (81) pivoted securing part (101) sits with its guide pin (102) in the horizontal portion (38) inclined guideway portion (39). The entrainment element (71) is positively and / or positively secured in the parking position (11) by means of the force of the energy accumulator (121) acting on the securing element (101) and the guide stub (102) holding the guideway section (39). When closing the drawer, the driver (5) contacts the stop surface (95) of the guide part (81). It is centered in the positive locking element (96). Upon further pushing the driver (5) moves the guide member (81) in the direction of the end position (12). The driving element (71) is released from the parking position (11). The securing part (101) pivots into the horizontal section (38) of the guide track (37). The stop surface (105) of the securing part (101) is in this case pivoted against the driver (5), which is thus held largely free of play between the two stop surfaces (95, 105). Due to the positive connection between the driver (5) and the acceleration and deceleration device (10), the position of the drawer or door is normal to the stroke direction (55) determined during the process. The drawer or door can thus be accurately guided even with a guide system with large Torleranzen.

In the acceleration and deceleration device (10), the driving element (71) acts on the piston rod (44) and on the Piston (45) of the cylinder-piston unit (41). According to the principle of self-help, the sealing collar (63) is pressed against the cylinder inner wall (51) with deformation immediately at the beginning of the retraction movement of the piston rod (44). The displacement space (65) is virtually hermetically separated from the compensation space (66). During further movement of the piston rod (44) in the direction of the cylinder bottom (43) is the

Volume of the displacement chamber (65) reduced. The gas pressure, e.g. the air pressure in the displacement chamber (65) increases and acts as an internal force on the piston sealing element (61) and on the brake sleeve (62). In addition, seals in the embodiment, the piston rod seal (58) at least in a portion of the piston rod stroke the compensation chamber (66) from the environment (1), whereby a vacuum is generated in the expansion chamber (66). The speed of the drawer or door is greatly slowed down.

With increasing stroke of the piston rod (44), the sealing collar (63) of the piston sealing element (61) reaches the beginning of the

Longitudinal groove (52). Once, as shown in Figure 5, the

Sealing collar (63) has passed the edge of the throttle channel (52), air is displaced from the displacement chamber (65) via the throttle channel (52) in the compensation chamber (66). The pressure in the displacement space (65) falls e.g. abruptly. The brake collar (62) can still rest against the cylinder inner wall (51).

The energy store (121) of the acceleration and deceleration device (10) discharging after being released from the parking position (11) pulls the entrainment element (71)

further in the illustration of Figure 4 to the right.

The piston rod (44) of the acceleration and deceleration device (10) is retracted further. As soon as that Piston seal (61) has completely detached from the inner wall (51), additional air flows from the displacement chamber (65) in the compensation chamber (66). The piston sealing element (61) resumes its initial position before the start of the lifting movement. The now almost closed drawer or door now has a low residual speed.

When the drawer is opened, the entrainment member (71) of the acceleration and deceleration device (10) is moved from the end position (12) shown in FIG. 3 in the direction of the parking position (11). In this case, the energy store (121) is charged by the tension spring (121) is tensioned. The piston (45) of the cylinder-piston unit (41) is extended. As soon as the guide pins (102) of the securing part (101) reach the second sections (39) of the guide tracks (37), the securing part (101) is supported by the energy store (121), possibly assisted by the driver (5) pivoted by the bearing ring (103) and the receiving portion (92) formed pivot joint (75) around. The guide member (81) remains in the horizontal portion (38) of the guide track (37). The entrainment member (71) is now in the parking position (11). The driver (5) is released. The drawer or door can now be opened almost without resistance.

The acceleration and deceleration device (10) can be used when closing and / or opening a drawer or door. The acceleration and deceleration device (10) may be constructed such that the displacement space (65) of the cylinder-piston unit (41) is arranged on the piston rod side. The parking position (11) of the carrier element (71) then faces the delay device (40). FIG. 8 shows a further acceleration and deceleration device (10) with a two-part carrier element (71). This device (10) is constructed largely as shown in Figures 1 to 7

Acceleration and deceleration device (10). The stop surface (95) of the guide part (81) carries a toothing (98). This oriented in the transverse direction

Positive locking element (98) allows automatic centering with a driver (5), which carries a corresponding counter-toothing.

The securing part (101) is, for example, identical to the securing part (101) shown in FIG. Its stop surface (105) may also be a positive locking element, e.g. a toothing, include. Also in this embodiment, the pivot joint (75), based on the securing part (101), between the stop surface (105) and the spring retainer (72) is arranged.

FIG. 9 shows a combined acceleration and deceleration device (10) whose driving element (71) has two stop parts (94, 104) staggered in the transverse direction (13). The stop surfaces (95, 105) are planes in this embodiment. But you can also have convex or concave positive locking elements, gears, etc. The remaining structure of the acceleration and deceleration device (10) shown in this figure 9 corresponds to the structure of the acceleration and deceleration devices (10) shown in Figures 1-8.

In FIG. 10, the guide part (81) and in FIG. 11 a securing part (101) of a device according to FIG. 9 are shown. Also in this embodiment, the pivoting joint (75) formed by the receiving area (92) and the pivotally mounted bearing ring (103). The guide pins (85, 87, 88, 102) and the spring receiver (72) are arranged as in the embodiment of Figures 6 and 7.

Figure 13 shows the use of a closing device (20) of the center door (6) of a sliding door system (7) of a piece of furniture (2), e.g. a cupboard (2). In the figure 14, the closing device (20) is shown enlarged. It comprises two acceleration and deceleration devices (10, 210) according to FIG. 9.

The illustrated sliding door system (7) has three sliding doors (4, 6, 8). The sliding door (4) shown on the left can be opened from the end position to the right and closed to the left. The sliding door (8) shown on the right is opened to the left and closed to the right. to

defined movement in the open and or closed end position can be used in each case a device according to Figures 1 to 9.

The middle door (6) of the cabinet (2) is guided in the representation of Figure 13 in front of the two outer doors (4, 8).

This center door (6) is wider than the distance between the two outer doors (4, 8) to each other, so that the center door (6) overlaps the other two doors (4, 8). The center door (6) can also be guided behind the outer doors (4, 8). When the doors (4, 6, 8) are closed, the front of the cabinet (2) is closed. Optionally, the doors (4, 6, 8) can be locked by means of additional locks.

From the position shown in Figure 13, the center door (6) in two opening directions (141), so both to the right (142) and to the left (143) apparently. To the To close the center door (6), this is first pushed manually from the respective open position in the opposite direction, for example, and then pulled by means of the center door closing device (20) in the closed position.

The center door closing device (20) is arranged, for example, on the upper side of the piece of furniture (2). But it can also - e. invisible from the outside - be arranged in the piece of furniture (2). An arrangement in the lower region of the cabinet (2) is conceivable.

Figure 14 shows the center door closing device (20) in an isometric view. It comprises a pair of pullers and brakes (21) consisting of two pulling and braking devices (10, 210). One of these pulling and braking devices (10) is mounted on the furniture body (3), the other (210) is fixed to the center door (6), e.g. screwed. In the following, the reference numbers refer to (210) on the second device (210). It is also conceivable, a pulling and AbbremsVorrichtung (10) on an outer door (4, 8) instead of

Furniture body (3) to arrange. In a cabinet (2) with more than three doors (4, 6, 8), a center door closing device (20) can be arranged on each of the non-outer doors. In the exemplary embodiment, both pulling and braking devices (10, 210) are combined acceleration and deceleration devices (10, 210). The two acceleration and deceleration devices (10, 210) which are identical in the representation of FIG. 14 are arranged symmetrically to a plane of symmetry which comprises the movement joint (9) between the furniture body (3) and the center door (6).

In the assembled state, cf. Figures 14 and 15, the guide member-side stop member (94, 294) of each Mit- facing element (71; 271) of the end position (12; 212) facing. This stop part (94, 294) arranged on the guide part (81, 281) will be referred to below as the pushing part (94, 294). The abutment surface (95; 295) of the thrust member (94; 294) is the thrust face (95; 295).

The stop part (104, 304) of the securing part (101, 301) facing the parking position (11, 211) in FIGS. 14 and 15 is referred to below as a pulling part (104, 304). Its stop surface (105; 305) is the traction surface (105; 305).

Figures 15-17 show the opening of the center door (6) to the right. In this case, the fixed furniture body (3) is shown at the top and the movable center door (6) at the bottom. The first pulling and braking device (10) is arranged on the furniture body (3) and the second pulling and braking device (210) is arranged on the sliding door (6). FIG. 15 as well as FIGS. 13 and 14 show the center door (6) in the closed basic position. The two pulling and braking devices (10, 210) are adjacent. The entrainment elements (71, 271) lie in the illustration of FIG

Figure 15 so that the tensile part (104) of the first device (10) from the tensile part (304) of the second device (210) is covered. The thrust part (94) of the first device (10) hides the thrust part (294) of the second device (210) in this illustration. The two driving elements (71, 271) are in their end positions (12, 212), cf. 14. The two cylinder-piston units (41, 241) are retracted, the energy stores (121, 321) are unloaded. The two entrainment elements (71, 271) are arranged such that one entrainment element (71, 271) is arranged opposite the other entrainment element (71, 271). element (271; 71) has the function of the above-described driver.

When opening the center door (6) to the right, cf. FIG. 16, the first pulling and braking device (10) remains in the starting position. The entrainment element (71) remains in its end position (12).

The second pulling and braking device (210) is displaced together with the center door (6). In this case, the pulling part (304) of the second device (210) contacts the pushing surface (95) of the first device (10) with its traction surface (305). The second driving element (271) is pulled out of the end position (212) in the direction of the parking position (211). In this case, the piston (245) of the cylinder-piston unit (241) is extended by means of the piston rod (244). At the same time, the tension spring (321) is tensioned, the energy store (321) is charged.

Even when the center door (6) is further opened in the opening direction (142), the entrainment element (71) of the first device (10) remains in the end position (12), cf. Figure 16. The

Guide pins (302) of the securing part (301) of the second carrier element (271) pass into the oblique sections (239) of the guide tracks (237). By means of the now tensioned tension spring (321), the second entrainment element (271) is secured in the parked position (211) in a force-locking and positive-locking manner. The energy store (321) is charged, the cylinder-piston unit (241) is extended, see. Figure 17. The traction surface (305) of the second entrainment member (271) has left the thrust surface (95) of the guide member (81) first Mitnähmeelements (71) when tilting the securing part (301) in the parking position (211). The surfaces (305, 95) are now separated. The tensile part (304) of the second Device (210) can pass the pushing part (94) of the first device (10). The center door (6) can now be opened almost without resistance further in the opening direction (142).

The closing of the opened to the right center door (6) takes place in the reverse order. The starting position is shown in FIG. 17, in which the center door (6) is open. In this position, the entrainment element (71) of the fixed

Acceleration and deceleration device (10) in the

End position (12). The entrainment element (271) of the second device (210) moved together with the center door (6) is in the parking position (11). At e.g. initially manual pushing the center door (6) in the Zuziehrichtung (145) abuts the thrust surface (295) of the second device (210) to the traction surface (105) of the first device (10), see. FIG. 20. The two stop parts (294, 104) form a contact pair (25). The

Carrier element (271) of the second device (210) is released from the parking position (211). Here it is in the

pivoted horizontal position in which the guide pins (302) in the horizontal portion (238) of the guideways (237) run. This is shown in FIG. 16. After this

Pivoting the securing part (301), the two contact pairings (25, 26) in the opening direction (141) only a small residual play, for example, is less than one millimeter. The energy store (321) of the second acceleration and deceleration device (210) discharging after being released from the parking position (211) pulls the second carrier element (271) further to the right. The contact pairing (25) between the traction surface (105) shown in FIG. 20 first device (10) and the thrust surface (295) of the second device (210) is relieved. The second driving element (271), which is driven further to the right by means of the further unloading spring (321), strikes the thrust face (95) of the first driving element (71) with its traction surface (305) of the securing part (301). The two abutment surfaces (305, 95) form the contact pairing (26), cf.

If appropriate, the two acceleration and deceleration devices (10, 210) can touch each other simultaneously both in the contact pairing (25) and in the contact pairing (26). The piston rod (244) of the second device (210) is retracted further. The center door (6) is retarded to its closed end position. If the center door (6) has been pushed vigorously, the first entrainment element (71) can also be pulled out of the end position (12) when the second entrainment element (271) is released from the parking position (211). In this overload protection of the energy storage device (121) of the first device (10) is partially charged, whereby the center door (6) is additionally braked. After that, the first energy store (121) relaxes again. The center door (6) has now only a low speed or it has even stopped. The further procedure of the door (6) takes place as described above.

As soon as the second driving element (271) his

End position (212) has reached, the center door (6) due to their inertia still within the in the

Lifting direction (55) oriented game of the two driving elements (71, 271) swing out. For example, both contact pairs (25, 26) are released. The drawn middle door (6) now returns to its original position. Figures 15, 18 and 19 show the opening of the center door (6) to the left, cf. FIG. 13.

When the center door (6) is opened to the left, the pull part (104) of the first device (10) arranged on the furniture body (3) contacts the push part (294) of the second device (210), cf. FIG. 18. The first carrier element (71) is pulled out of the end position (12). The tension spring (121) of the first device (10) is tensioned. The piston (45) of the first cylinder-Koiben unit (41) is extended. The second driving element (271) remains in the end position (212). The second energy store (321) is relaxed. The second cylinder-piston unit (241) is retracted. As soon as the first carrier element (71) has reached its parking position (11), cf. 19, the center door (6) can be opened almost without resistance in the opening direction (143). The pulling surface (105) of the first device (10), which tilts when tilting the securing part (101) of the first driving element (71) into the parking position (11), has detached from the pushing surface (295) of the second device (210).

The closing of the center door (6) from the left, so in the

The closing direction (144) is shown in FIGS. 19, 18 and 15. In the starting position shown in FIG. 19, the entrainment element (71) of the first device (10) in the parking position (11) and the entrainment element (271) of the second device (210) in the end position (212). When sliding the center door (6), the pulling part (304) of the second device (210) contacts the pushing part (94) of the first device (10), cf. FIG. 21. The two stop parts (94, 304) form a contact pairing (26). The driving element (71) of the first device (10) is from the Parking position (11) solved, cf. Figure 18. The securing part (101) pivots in the horizontal position. The piston rod (44) of the first cylinder Koiben unit (41) is retracted. In this case, the pressure building up in the displacement chamber (65) initially causes a strong deceleration of the

Center door (6). Optionally, the second Mitnähmeelement (271) can be pulled out of the end position (212) as an overload protection here. The center door (6) now has only a small residual speed. The second entrainment element (271) returns to its end position (212).

With the triggering of the driving element (71) from the parking position (11), the tension spring (121) of the first device (10) relaxes. It pulls the entrainment element (71) in

Direction of the end position (12). The contact pairing (26) is relieved or released. The entrainment element (71) of the first device (20) is retracted until its traction surface (105) contacts the thrust surface (295) of the second entrainment element (271). The abutment part (104) of the first securing part (101) bears against the abutment part (294) of the second guide part (281), forming a contact pairing (25). The center door (6) is pulled further in the closing direction (144). By means of the first tension spring (121), the first carrier element (71) is pulled into the end position (12). The piston (45) is retracted. The mass moment of inertia of the center door (6) can now solve the contact pairing (25) of the tension surface (105) of the first driving element (71) and the thrust surface (295) of the second driving element (271). The center door (6) assumes its closed starting position shown in FIGS. 13, 14 and 15. The two pulling and braking devices (10, 210) can also be arranged so that the cylinder-piston units (41, 241) point to the left. The sequence of movements is then analogous to the procedure described above.

The train and deceleration device pair (21) may have two different traction and deceleration devices (10; 210). These may for example have different stroke and / or different cross section. The speed profile over the stroke when closing from the right can be different from the speed profile over the stroke at the same time

Close from the left.

One or both of the pulling and braking devices (10, 210) can also be constructed such that their displacement space is arranged between the piston and the cylinder head of the cylinder-piston unit. In such a device, the piston rod is retracted in the parking position and in the

Extended end position. The definitions of the tensile and shear surfaces correspond to the above definition.

In the exemplary embodiment, the pulling and braking devices (10, 210) have pneumatic retarding devices. However, it is also conceivable to use pneumatic dampers whose displacement space communicates with the environment (1). The use of hydraulic dampers is conceivable. In the latter dampers, the piston rod may be spring-loaded extendable and abut with an abutment surface on the driving element.

Combinations of the individual embodiments are conceivable. List of reference numbers:
