Description

The invention relates to a deceleration device with a housing, with a cylinder-piston unit mounted in the housing and having a cylinder and a piston, and with a driving element which is mounted in the housing between a non-positively and/or positively secured parking position and an end position and can be moved back. wherein the driving element loads the piston relative to the cylinder at least when moving in the direction of the end position and wherein the driving element comprises a slide and a pull pin pivotally mounted thereon in a pivot joint, the pull pin having at least one guide in the housing, at least in one adjacent to the end position Lifting section is rigidly connected to a guide pin that can be moved parallel to the carriage, as well as a combined acceleration and deceleration device with such a deceleration device and with a spring energy storage that can be loaded and unloaded repeatedly, the spring energy storage being charged when the driving element is in the parking position and when the driving element is in the end position is discharged to a residual energy value and the spring energy storage loads the driving element in the direction of the end position.

From the DE 10 2011 010 778 A1 Such a retraction device is known. When the retraction device is triggered, knocking noises may occur. Damage to the cylinder-piston unit, the driving element and/or the guideway can limit the service life.

The DE 20 2008 000 749 U1 discloses a retraction device with a slide and a double hook lever pivotably mounted therein. A wedge-shaped notch in the guideway allows the double hook lever to be temporarily swiveled in to grasp a hook.

From the WO 2007/111 424 A1 and the WO 2012/015 294 A1 Retraction devices are known with a driving element that can be pivoted relative to a carriage, with the respective parking position being secured by means of a retraction spring.

In the WO 2018/001 403 A1 According to the applicant, the driving element guide part is guided in the housing by means of sliding pins. The driving element is mounted in the elongated holes and on the driving element guide part.

The present invention is based on the problem of developing a low-noise deceleration device with a long service life.

This problem is solved with the features of the main claim. For this purpose, a stop pin is pivotally mounted in the carriage. The housing or carriage has a wedge-shaped receptacle that limits the pivot angle range of the pull pin in the park position. The guide pin can be clamped in the wedge-shaped holder. In addition, the pull pin can be displaced from the parking position relative to the carriage by means of a pivoting movement of the stop pin.

The acceleration and deceleration device is constructed in such a way that the spring energy storage is held on the carriage and on the housing. In the park position, the guide pin rests on a guide slot of the housing. In addition, in the parking position, the force component of the spring force applied to the guide pin and oriented parallel to the guide link points in the direction of the end position, so that the housing blocks a longitudinal displacement of the driving element.

A deceleration device and a combined acceleration and deceleration device with such a deceleration device are described below, which have a driving element that is self-locking in the parking position. For this purpose, a pull pin is pivoted relative to a slide in the park position. The pull pin is clamped and secured on the slide or on the housing using a wedge holder. When used in a combined acceleration and deceleration device, the pull pin is loaded relative to the housing in the parking position, so that movement of the driving element in the closing direction is blocked.

The release from the parking position is carried out by a pivoting movement of the stop pin, which acts on the pull pin. This results in a small gradient in the increase in forces on the pull pin and on the driving element, so that no impact noises occur.

The 1 , 7 and 8th show a delay device (21) in two operating states. Such deceleration devices (21) are used to brake furniture parts that move relative to one another, for example a drawer or a sliding door and a furniture body, before they reach an open or closed end position. The delay device (21) is attached to one of the two pieces of furniture. A driver (2) or activator is attached to the other piece of furniture. When the two pieces of furniture are moved in the direction of one of the end positions mentioned, the driver (2) couples with a driver element (61) of the delay device (21) in a partial stroke adjacent to this end position. After coupling, a deceleration force acts on the relative movement of the two furniture parts to one another. The moving piece of furniture is braked.

The representation of the 1 shows the delay device (21) in an end position (22). For example, the drawer is closed. The deceleration device (21) comprises a housing (31) in which the driving element (61) is movably mounted. The housing (31) is cuboid. It comprises a lower housing shell (32) and an upper housing shell (33). The two housing shells (32, 33) are joined together. For example, they are screwed together, glued, welded, etc.

The housing (31) has its stepped top (34). The higher housing attachment (35) is designed to be closed. In the lower area, the top (34) has a longitudinal slot (36). The driving element (61) projects into the surroundings (1) through this longitudinal slot (36). The driving element (61) shown is designed in three parts. It has a carriage (62) on which a release lever (82) and a pull pin part (102) are pivotally mounted. On the area of the driving element (61) facing the housing attachment (35), it has a piston rod head receptacle (63). In the exemplary embodiment, a piston rod head (112) of a cylinder-piston unit (111) mounted in the housing (31) sits in the piston rod head receptacle (63). It is also conceivable to design the driving element (61) without a piston rod head receptacle (63). For example, the piston rod head (112) can then rest on the driving element (61).

The 2 shows a lower housing shell (32) from the inside (37). The upper housing shell (33) is, for example, designed symmetrically to this. The lower housing shell (32) has a circumferential edge web (38) which is interrupted in the area of the longitudinal slot (36). A cylinder receptacle (39) is formed in the area of the housing attachment (35). The cylinder receptacle (39) has the shape of a half-shell oriented in the longitudinal direction (25) of the deceleration device (21). The housing attachment (35) has a piston rod opening (41) in the direction of the longitudinal slot (36). For example, the cylinder (113) of the cylinder-piston unit (111) is inserted into the cylinder holder (39), cf. 7 . The piston rod (114) then protrudes through the piston rod opening (41). It is also conceivable to mount the cylinder-piston unit (111) in such a way that the piston rod head (112) points towards the rear wall (42) of the housing. The cylinder (113), which can then be displaced in the longitudinal direction (25) in the housing (31), is then oriented in the direction of the driving element (61). In this case, the housing opening (41), referred to as the piston rod opening (41), has the cross section of the cylinder holder (39).

Below the longitudinal slot (36), the lower housing shell (32) shown has two guide tracks (43, 44). A first guide track (43) is oriented in the longitudinal direction (25). For example, its length is 76% of the length of the cylinder holder (39). This first guide track (43) has a constant height oriented in the height direction (26) and a constant width oriented in the width direction (27) over its entire length.

A second guideway (44) is shown in the illustration 2 below the first guideway (43). In the exemplary embodiment, its length in the longitudinal direction (25) is 80% of the length of the first guideway (43). The end (45) of the second guide track (44) facing the cylinder receptacle (39) is offset from the corresponding end (46) of the first guide track (43). In the exemplary embodiment the second guideway is (44) offset from the first guide track (43) by 19% of the length of the first guide track (43) in the direction away from the cylinder holder (39). The second guide track (44) has an expansion (47) at the end facing away from the cylinder holder (39). This is in the direction away from the first guide track (43), in the illustration 2 i.e. directed downwards. In the exemplary embodiment, the length of this expansion (47) is 13% of the length of the second guide track (44). In the exemplary embodiment, the expansion (47) is limited in the direction of the cylinder receptacle (39) by a wedge receptacle (48). This has an opening angle of, for example, 25 degrees. This angle can be between 10 degrees and 30 degrees, for example. The opening of the wedge holder (48) is oriented in the direction away from the cylinder holder (39). The height of the expansion (47) in the height direction (26) is, for example, two and a half times the height of the second guide track (44). In the upper area, the widening (47) merges into an inlet slope (49).

The second guide track (44) can be designed as a guide link (55) both in the lower housing shell (32) and in the upper housing shell (33). This then includes those in the representation 2 bottom boundary of the guideway (44) and the inlet slope (49). The expansion (47) can be limited by the outer wall of the housing (31).

In the 3 the carriage (62) of the driving element (61) is shown in an isometric view. The carriage (62) has the piston rod head holder (63) on its back. A thrust pin (64) protrudes upwards normal to the longitudinal direction (25). In the representation of the 1 this thrust pin (64) protrudes into the surroundings (1). The thrust surface (65), which is designed as a flat surface, points in the direction away from the piston rod head receptacle (63). Two longitudinal webs (66) arranged parallel to one another also point in this direction. Two transverse openings (67, 68) oriented normal to the longitudinal direction (25) penetrate both longitudinal webs (66). The transverse openings (67, 68), for example, have a circular cross-sectional area and serve as sliding and pivot pin receptacles (67, 68). A connecting web (69) connects the two longitudinal webs (66) between the sliding and pivot pin receptacles (67, 68). The plane of the thrust surface (65) is perpendicular to the plane spanned by the sliding and pivot pin receptacles (67, 68). Two guide webs (71) are arranged on the side of the thrust surface (65). These are aligned with the longitudinal webs (66). On its underside, the carriage (62) has a fork-shaped receptacle (72) with a largely cylindrical receiving section (73). The carriage (62) can also be designed without the fork-shaped receptacle (72).

The 4 shows the release lever (82). This has an at least approximately central pin receptacle (83), from which a stop pin (84) and an actuating arm (85) protrude. The pin receptacle (83) has the same cross-sectional area as the first sliding and pivot pin receptacle (67). The actuating arm (85), for example, is 50% longer than the stop pin (84). The length of the actuating arm (85) is shorter than the distance between the two sliding and pivot pin receptacles (67, 68) of the slide (62). The angle enclosed by the stop pin (84) and the actuating arm (85) is 125 degrees in the exemplary embodiment. The end face (86) of the actuating arm (85) is designed to be oblique. For example, it encloses an angle of 55 degrees with a line of gravity of the actuating arm (85) through the central axis of the pin holder (83). In the exemplary embodiment, the center of gravity of the release lever (82) lies in the contact surface (87) of the stop pin (84).

In the 5 the tension pin part (102) is shown. In the exemplary embodiment, the tension pin part (102) has, for example, a central pin receptacle (103), from which a pin leg (104) and a guide leg (105) protrude. The guide leg (105) and the pin leg (104) form an angle of 130 degrees with each other, for example. The pin leg (104) has, for example, a flat pull pin surface (106). It is also referred to below as a tension pin (104).

The guide leg (105) has a guide pin (107) on both sides. The width of the guide leg (105) in the area of the guide pin (107) is, for example, twice as large as in the remaining area of the pull pin part (102). The pull pin part (102) can also have a one-sided guide pin (107). The individual guide pin (107) is shown in the illustration 5 an oval cross-sectional area. Its length in the longitudinal direction (25) is twice as large as its height when the driving element (61) is in the end position (22). In this position, the guide pins (107) protrude from the slide (62) on the side facing away from the cylinder-piston unit (111). The plane spanned by the two center lines of the guide pin (107) is normal to the tension pin surface (106).

The individual guide pin (107) can also be cylindrical, ellipsoidal, etc.. It is also conceivable to design the pull pin part (102) with several pins. These can be relative to each other in the height direction (26) and/or which should be offset from one another in the longitudinal direction (25).

The 6 shows a longitudinal section in the 1 and 7 Cylinder-piston unit (111) shown. The hydraulic cylinder-piston unit (111), for example, comprises the cylinder (113), in which a piston (115) which can be displaced by means of the piston rod (114) delimits a displacement space (116) from a compensation space (117). The displacement space (116) lies between the piston (115) and the cylinder base (118). The compensation chamber (117) is arranged between the piston (115) and the cylinder head (119). In the compensation chamber (117) there is also a spring-loaded compensation sealing element (121), which sits sealingly on the piston rod (114). The piston rod (114) penetrates the cylinder head (119). The cylinder (113) and the piston rod (114) have the same central axis (122), which penetrates the cylinder-piston unit (111) in the longitudinal direction (25). In the exemplary embodiment, both the cylinder (113) and the piston rod (114) are designed coaxially to this central axis (125). The cylinder-piston unit (111) can also be designed as a pneumatic cylinder-piston unit (111). In this case, the compensating sealing element (121) may be omitted. It is also conceivable to arrange a return spring in the displacement space (116). In this case, the piston rod head (112) can be designed without a connection to the slide (62).

The cylinder-piston unit (111) can also be designed with a displacement space (116) arranged between the piston (115) and the cylinder head (119). The compensation chamber (117) is then located between the piston (115) and the cylinder base (118). In this case, the deceleration of the cylinder-piston unit (111) acts when the piston (115) and the piston rod (114) are extended.

When assembling the deceleration device (21), for example, the cylinder-piston unit (111) is first inserted into the lower housing shell (32). The release lever (82) and the pull pin part (102) are inserted into the carriage (62). Both components (82, 102) are each secured with a pivot and sliding pin (74, 76). These pivot and sliding pins (74, 76) are inserted through the transverse openings (67, 68) of the slide (62) and the pin receptacles (83, 103) of the release lever (82) and the pull pin part (102). In the exemplary embodiment, they form the release lever swivel joint (77) and the pull lever swivel joint (78). The carriage (62) with the components (82, 102) inserted thereon is then inserted into the lower housing shell (32), so that the pivot and sliding pins (74, 76) are in the first guide track (43) and the guide pin (107) in the second guideway (44) is inserted. The piston rod head (112) is inserted into the piston rod head receptacle (63). Finally, the housing (31) is closed by placing the upper housing shell (33). A different order of assembly is also conceivable.

The 7 shows the delay device (21) with the upper housing shell (33) removed in the 1 shown end position (22). For example, the delay device (21) is arranged on the furniture body and the driver (2) on a drawer that can be moved relative to it. The piston rod (114) of the cylinder-piston unit (111) is retracted. The driving element (61) is in the end position (22). A straight line oriented in the longitudinal direction (25), in which the central axis (122) of the cylinder-piston unit (111) lies, penetrates the thrust surface (65) in the normal direction. The driver (2) sits in the driver recess (75) of the driver element (61). It rests on the stop pin (84) of the release lever (82). The release lever (82) is supported on the thrust surface (65) of the slide (62). If necessary, the pull pin part (102) can also rest on the driver (2).

The drawer or the sliding door is closed, for example, when the driving element (61) is in this position.

When opening the drawer, the driver (2) pulls the driver element (61) relative to the housing (31) in the opening direction (3). The driver (2) rests on the pull pin part (102). The pull pin part (102) with the pull pin (104) is prevented from moving relative to the area adjacent to the end position (22) by means of the pivot and sliding pins (74, 76) guided in the housing (31) and the guide pins (107). Carriage (62) hindered. The carriage (62) also pulls the piston rod (114) with the piston (115) in this direction relative to the cylinder (113). In the case of a cylinder-piston unit (111) with spring return, the carriage (62) can become detached from the piston rod (114) when the carriage (62) is moved in the opening direction (3).

As soon as the at least one guide pin (107) reaches the recess (47), the driver (2) loading the pull pin (104) causes a pivoting movement of the pull pin part (102) in the pull pin swivel joint (78). The pull pin part (102) with the pull pin (104) pivots through a pivot angle between 90 degrees and 110 degrees. In the exemplary embodiment, the pivot angle is 95 degrees. The guide pins (107) dip into the expansion (47). During further movement of the driver (2) relative to the deceleration device (21), the pull pin part (102) is pivoted further. The guide pin (107) moves into the wedge-shaped receptacle (48). Here, for example, it is clamped. The pivoting angle of the pull pin (104) is therefore limited by means of the wedge-shaped receptacle (48). The guide pins (107) block in this parking position (23), cf. 8th , pivoting the pull pin part (102) and moving the carriage (62). The release lever (82) can rest on the pull pin part (102) with its actuating arm (85).

In the representation of the 8th the driver (2) has left the delay device (21). The driving element (61) is in the parking position (23), which is secured by force and/or positive locking. The drawer can now be opened further with almost no resistance. The release lever (82) is in a ready position (88). For example, it lies against the carriage (62) with a line on its back side (89) oriented in the transverse direction (27). The piston rod (114) of the cylinder-piston unit (111) is extended. For example, if the cylinder-piston unit (111) is designed with a return spring, the wedge receptacle (48) for a locking pin of the pull pin part (102) can be arranged in the carriage (62).

When the drawer is closed again, the driver (2) moves relative to the delay device (21) in the closing direction (4). The driving element (61) is initially still in the 8th shown parking position (23). The driver (2), for example, moves above the pull pin part (102) without touching it. When the drawer is closed further, the driver (2) contacts the stop pin (84) of the release lever (82). The release lever (82) is pivoted around the release lever pivot joint (77). The stop pin (84) is pressed against the thrust surface (65) of the carriage (62). The piston rod (114) of the cylinder-piston unit (111) is loaded centrally. In the exemplary embodiment, the side oriented towards the slide (62), for example the underside, of the driver (2) is offset in the direction of the slide (62) from or at the height of the central axis (122) of the cylinder-piston unit (111). containing straight lines. No torque is transmitted to the cylinder-piston unit (111). At the same time, the actuating arm (85) of the release lever (82) loads the pull pin part (102) in the area of the guide pins (107). The guide pins (107) are released from the wedge holders (48). The pull pin part (102) leaves the parking position (23), cf. 9 . In this representation the 9 the carriage (62) is shown cut along a vertical central longitudinal plane.

The carriage (62) loaded in the closing direction (4) also pulls the pull pin part (102) in this direction. The guide pins (107) of the pull pin part (102) move along the guide slots (55) on the housing side. The draw pin part (102) is pivoted around the draw pin swivel joint (79). The carriage (62) loads the piston rod (114) of the cylinder-piston unit (111). The piston (115) is retracted and, for example, displaces oil from the displacement space (116) into the compensation space (117). The movement of the driving element (61) is delayed. The closing movement of the drawer is braked via the driver (2).

The 10 shows the driving element (61) as the drawer continues to close. The driving element (61) coupled to the driver (2) continues to move in the closing direction (4). The piston rod (114) of the cylinder-piston unit (111) has retracted further. The pull pin part (102) is pivoted further towards the operating position (108), in which the pull pin (104) protrudes from the housing (31), cf. 7 . The guide pins (107) have moved along the inlet slope (49) of the guide link (55) in the direction of the horizontal section (51) of the second guide track (44).

The further retraction movement of the drawer is further delayed until the driving element (61) is in the 1 and 7 has reached the end position (22) shown.

The 11 and 12 show a combined acceleration and deceleration device (10) with the upper housing shell (33) removed. In the representation of the 11 the driving element (61) is in the end position (22). The 12 shows the same combined acceleration and deceleration device (10) with the driving element (61) in the parking position (23). The combined acceleration and deceleration device (10) has an acceleration device (11) and a deceleration device (21) which interacts with it. The delay device (21) is largely constructed in the same way as in connection with the one in the 1 - 10 illustrated embodiment described. However, the housing (31) has additional receiving pins (52) for deflection rollers (53) and a tension element holder (54).

The acceleration device (11) connects the carriage (62) to the housing (31). A pull sleeve (12) is mounted in the fork-shaped receptacle (72) of the carriage (62), in which a pull cable (13) is attached. In the exemplary embodiment, this pull cable (13) is guided around two deflection rollers (53) of different diameters and is connected by means of a transition sleeve (14) to a spring energy storage device (15) oriented, for example, in the longitudinal direction (25). This spring energy storage (15) is, for example, one Tension spring (15). This tension spring (15) is relaxed to a residual energy value when the driving element (61) is in the end position (22) and is tensioned to a maximum operating value when the driving element (61) is in the parking position (23). The difference in length between the tensioned and relaxed spring energy storage (15) corresponds, for example, to the stroke of the driving element (61) from the parking position (23) to the end position (22). On the side facing away from the pull rope (13), the spring energy storage (15) is inserted into the pull element holder (54). In the relaxed state, the spring energy storage (15) is longer than the extended cylinder-piston unit (111). This means that the tension spring (15) can be operated in the linear range of the force-travel characteristic.

The acceleration device (11) can also be designed without a pull rope (13). The spring energy storage (15) can then be guided around the deflection rollers (53) or connect the carriage (62) directly to the housing (31). Another arrangement of the acceleration device (11) is also conceivable.

It is also conceivable to construct the acceleration device (11) in the form of a pulley. Here, for example, in addition to the deflection rollers (53) arranged in the housing (31), another deflection roller is arranged on the carriage (62). This allows the force on the carriage (62) to be metered within narrow limits.

When assembling the acceleration and deceleration device (10), for example, the elements of the deceleration device (21) are first assembled as described above. For example, the spring energy storage (15) is then connected to the pull rope (13). This unit is then placed around the deflection rollers (53) and hooked into the carriage (62) and the housing (31). The tension spring (15) then acts on the carriage (62) via the deflection rollers (53). The spring energy storage (15) is thus held on the carriage (62) and on the housing (31).

In the parking position (23), the guide pins (107) rest on the guide slots (55). The force component of the spring force applied to the guide pin (107) and oriented parallel to the guide link (55) points in the direction of the end position (22). The guide pins (107) thus block the position of the driving element (61) relative to the housing (31). In the exemplary embodiment, these guide pins (107) simultaneously secure the position of the tension pin part (102) relative to the carriage (62) by clamping in the wedge holder (48). These two functions can also be implemented using components that are spatially separated from one another. For example, as described in connection with the first exemplary embodiment, the position of the tension pin part (102) relative to the carriage (62) in the parking position (23) can be adjusted by means of a non-positive and/or positive connection between the tension pin part (102) and the carriage (62) must be secured.

The driving element (61) is released from the parking position (23) as described in connection with the first exemplary embodiment. There are no impact noises. In this case too, the force is applied to the thrust surface (65) without being deflected into the cylinder-piston unit (111). This prevents damage to the driving element (61) and/or the housing (31). After the driving element (61) has been triggered, both the deceleration force of the deceleration device (21) and an acceleration force caused by the relaxing spring energy storage (15) act on the driving element (61). Due to the long tension spring (15), there is a very flat spring characteristic. The resultant of the superimposed acceleration and deceleration forces conveys the driving element (61) into the end position (22) in a controlled manner. Here it stops without hitting. For example, the drawer is now closed.

When the drawer is opened, the driving element (61) is also pulled in the opening direction (3) in this exemplary embodiment. The piston (115) is extended in the cylinder-piston unit (111). The spring energy storage (15) is being charged. As soon as the driving element (61) has reached the parking position (23), the driver (2) decouples. The drawer can now be opened further.

In the 13 A two-part driving element (61) is shown. This can be used both in a deceleration device (21) and in a combined acceleration and deceleration device (10), as described in connection with the previous exemplary embodiments. This one in the 13 The driving element (61) shown has a carriage (62) and a double lever (81) pivotably mounted therein. The pivot and sliding pins (74, 76) are in this 13 not shown. The representation of the 13 shows the driving element (61) in the position of the end position (22).

The carriage (62) is constructed largely in the same way as the one in the 3 shown carriage (62). The first sliding and pivot pin receptacle (67) is arranged below the thrust pin (64). The shear surface (65) is a continuous flat surface. It is arranged normal to the plane of the transverse openings (67, 68). In addition, a normal to the thrust surface (65) penetrates the piston rods head holder (63) or a slide-side stop surface of the piston rod (114).

The double lever (81) is pivotably mounted in the second sliding and pivot pin receptacle (68) of the carriage (62). The position of the second sliding and pivot pin receptacle (68) relative to the thrust surface (65), for example, corresponds to the conditions in the 3 shown carriage (62).

In the representation of the 13 For example, the oval guide pin (107) lies in a plane parallel to the plane of the sliding and pivot pins (74, 76). In this exemplary embodiment too, the guide pin (107) can be like that in the 5 shown guide pin (107) can be formed.

The 14 shows the double lever (81) in a side view. It has a pull pin (104) and a stop pin (84). The pull pin (104) is designed like the one in the 5 Tie pin (104) shown. Its arrangement relative to the guide pins (107) also corresponds to the conditions in the 5 shown pull pin part (102).

The stop pin (84) is formed on the pull pin (104). In the exemplary embodiment, the stop pin (84) is connected to the tension pin (104) in the area of the guide pin (107). The stop pin (84) is curved. The imaginary center line of the arch (91) is oriented in the transverse direction (27) and lies above the stop pin (84) when the tension pin (104) is in the operating position (108). In this position of the double lever (81), cf. 13 , the stop pin (84) is below the carriage (62). The stop pin (84) is therefore at least approximately normal to the pull pin (104).

The stop pin (84) can be designed to be elastically deformable. For example, the arch (91) can be bendable. It is also conceivable to make the connection of the stop pin (84) to the pull pin (104) flexible.

The 15 shows that in the 13 and 14 driving element (61) shown in the parking position (23) in a lower housing shell (32). The lower housing shell (32) is constructed, for example, as described in connection with the previous exemplary embodiments. The carriage (62) is shown cut along a vertical central longitudinal plane.

The double lever (81) is pivoted, for example, by an angle of 95 degrees compared to the end position (22). The pivoting direction of the pull pin is oriented in the opening direction (3) when pivoting into the parking position (23). In the parking position (23), the pull pin (104) has the same position relative to the carriage (62) as in the pull pin (104) described in connection with the previous exemplary embodiments. The guide pins (107) are secured in the wedge-shaped receptacles (48) of the second guide tracks (44). This means that both the parking position (23) is fixed and the driving element (61) is blocked from moving in the closing direction (4).

The stop pin (84), for example, protrudes from the carriage (62) by a third of its length. It protrudes into the driving recess (75). The part of the stop pin (84) protruding from the carriage (62) is offset from the second pivot and sliding pin (76) in the direction of the thrust surface (65).

When the driver (2) moves relative to the driver element (61) in the closing direction (4), the driver (2) first contacts the stop pin (84). The double lever (81) experiences a torque about the pivot joint (78) with the second sliding and pivot pin (76). In the representation of the 15 the double lever (81) is pivoted clockwise. This releases the locking of the double lever (81), for example in the housing (31). The double lever (81) leaves the parking position (23). The pull pin (104), pivoted with the double lever (81), limits the play of the driver (2) relative to the driver element (61) in the opening direction (3).

As the driver (2) moves further in the closing direction (4), the stop pin (84) is displaced into the carriage (62). The guide pins (107) roll on the guide slots (55). The double lever (81) is pivoted further. At the same time, the driving element (61) moves in the direction of the end position (22). Here, the deceleration device (21) and possibly the acceleration device (11) act on the driving element (61), as described above.

Combinations of the individual exemplary embodiments are also conceivable.
