Description

Delay device with multi-part driving element

Description :

The invention relates to a delay device with a housing, with a bearing mounted in the housing, a cylinder and a piston having a cylinder-piston unit and with egg nem in the housing between a non-positive and / or positively secured parking position and an end position and back slidably mounted ver Driving element, 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 pulling pin pivotally mounted in a swivel joint, the pulling pin having at least one guided in the housing, at least is rigidly connected in a stroke section adjacent to the end position, parallel to the slide, and a combined acceleration and deceleration device with such a deceleration device and with

Confirmation copy a repeatably loadable and unloadable spring energy storage device, the spring energy storage device being charged in the parking position when the driving element is in the position and being discharged to a residual energy value when the driving element is in the end position, and wherein the spring energy storage device loads the driving element in the direction of the end position.

Such a Einzugvor direction is known from DE 10 2011 010 778 A1. Knocking noises can occur when the feed device is triggered. Damage to the cylinder-piston unit, the driving element and / or the guideway can limit the service life.

The problem underlying the present invention is to develop a low-noise delay 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 slide. The housing or the slide has a wedge-shaped receptacle that limits the swivel angle range of the draw pin in the park position. In addition, the pull pin can be displaced from the park position by means of a pivoting movement of the stop pin relative to the slide.

The acceleration and deceleration device is constructed in such a way that the spring energy store is held on the slide and on the housing. In the park position, the guide pin lies against a guide link of the housing. In addition, in the parking position, the Force component of the spring force oriented parallel to the guide link in the direction of the end position, so that the housing blocks a longitudinal displacement of the driving element.

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

It is released from the parking position by a swiveling movement of the stop pin, which acts on the pull pin. This results in a small gradient of the increase in the forces on the pulling pin and on the driving element, so that no striking noises occur.

Further details of the invention emerge from the subclaims and the following description of schematically illustrated embodiments.

Figures 1, 7 and 8 show a delay device

device (21) in two operating states. Such delay devices (21) are used to brake relatively moving furniture parts, such as a drawer or a sliding door and a furniture body, before reaching 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 moving the two pieces of furniture in the direction of one of the above Endla conditions in a partial stroke adjacent to this end stroke of the driver (2) with a driving element (61) of the delay device (21). After coupling, a deceleration force acts on the relative movement of the two pieces of furniture to each other. The moving piece of furniture is braked. The illustration in FIG. 1 shows the delay device (21) in an end position (22). For example, the drawer is closed. The delay device (21) comprises a housing (31) in which the driving element (61) is mounted to be movable. The housing (31) is cuboid out. 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 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 constructed in three parts. It has a carriage (62) on which a release lever (82) and a Zugzap fteil (102) are pivotally mounted. At the area of the driving element (61) facing the housing attachment (35), this 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 form the Mitnahmele element (61) without piston rod head receptacle (63). For example, the piston rod head (112) can then rest on the receiving element (61).

Figure 2 shows a lower housing shell (32) from the inside (37). The upper housing shell (33) is, for example, symmetrical to this. The lower housing shell (32) has a circumferential edge web (38) which is interrupted in the region of the longitudinal slot (36). A cylinder receptacle (39) is formed in the area of the housing attachment (35). The Zy Linderaufnahme (39) has the shape of a half-shell oriented in the longitudinal direction (25) of the delay device (21). In the direction of the longitudinal slot (36), the housing attachment (35) has a piston rod opening (41). For example, the cylinder (113) of the cylinder-piston unit (111) is inserted into the cylinder receptacle (39), cf. Figure 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) faces the rear wall of the housing (42). 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) designated as the piston rod opening (41) has the cross section of the cylinder receptacle (39).

Below the longitudinal slot (36), the housing lower shell (32) shown has two guideways (43, 44). A first guideway (43) is oriented in the longitudinal direction (25). Their length is, for example, 76% of the length of the cylin deraufnahme (39). This first guideway (43) has a constant, in the height direction (26) oriented height and a constant in the width direction (27) oriented width over its entire length.

A second guideway (44) lies in the representation of the figure 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 cylinder (39) facing end (45) of the second guideway (44) is offset from the corresponding end (46) of the first guideway (43). In the exemplary embodiment, the second guideway (44) is offset from the first guideway (43) by 19% of the length of the first guideway (43) in the direction facing away from the cylinder receptacle (39). On the of the cylinder holder (39) opposite end, the second guideway (44) has a widening (47). This is directed in the direction facing away from the first guideway (43), ie downwards in the illustration in FIG. 2. The length of this expansion (47) in the exemplary embodiment is 13% of the length of the second guide track (44). In the direction of the cylinder holder (39) in the exemplary embodiment, the widening (47) is limited by a

Wedge holder (48). This has an opening angle of e.g.

25 degrees. This angle can be between 10 degrees and 30 degrees, for example. The opening of the wedge seat (48) is oriented in the direction facing away from the cylinder seat (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) changes into an inlet slope (49).

The second guideway (44) can be formed both in the lower housing shell (32) and in the upper housing shell (33) as a guide slot (55). This then includes the lower limit of the guide track (44) in the illustration in FIG. 2 and the run-in slope (49). The demonstration

device (47) can be limited by the outer wall of the housing (31).

In Figure 3 is the carriage (62) of the Mitnahmele

elements (61) is shown in an isometric representation. The carriage (62) has the piston rod head receptacle (63) on its rear. A thrust pin (64) protrudes upward from the longitudinal direction (25). In the illustration in FIG. 1, this push pin (64) projects into the surroundings (1). The thrust surface (65) designed as a flat surface points in the direction facing away from the piston rod head receptacle (63). Two parallel ones also point in this direction Longitudinal webs (66). Two transverse openings (67, 68) oriented normal to the longitudinal direction (25) penetrate both longitudinal webs (66). The transverse openings (67, 68) have, for example, a circular cross-sectional area and serve as slide and pivot pin receptacles (67, 68). Between the sliding and

Trunnion receptacles (67, 68) connects a connecting web (69) the two longitudinal webs (66). The plane of the thrust surface (65) is perpendicular to the plane spanned by the slide and pivot pin receptacles (67, 68). Two guide webs (71) are arranged to the side of the push 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 receptacle

cut (73). The carriage (62) can also be formed without the gabelför shaped receptacle (72).

Figure 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) is, for example, 50% longer than the stop pin (84). Here, the length of the actuating arm (85) is shorter than the distance between the two sliding and pivot pin receptacles (67, 68) of the carriage (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 formed obliquely. For example, it includes an angle of 55 degrees with a line of gravity of the actuating arm (85) through the central axis of the pin receptacle (83). The center of gravity of the release lever (82) in the exemplary embodiment lies in the contact surface (87) of the stop pin (84). FIG. 5 shows the pull pin part (102). The pull pin part (102) in the exemplary embodiment 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) include, for example, an angle of 130 degrees. The pin leg (104) has, for example, a flat pull pin surface (106). It is also referred to below as the pull pin (104).

The guide leg (105) carries 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 rest of the area of the pull pin part (102). The tension pin part (102) can also have a one-sided guide pin (107). The individual guide pin (107) has an oval cross-sectional area in the position shown in FIG. 5. Its length in the longitudinal direction (25) is in the position of the Mitnahmele element (61) in the end position (22) twice as large as its height. 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 pull pin surface (106).

The individual guide pin (107) can also be cylindrical, ellipsoid-shaped, etc. It is also conceivable to design the pull pin part (102) with a plurality of pins. These can be offset relative to one another in the height direction (26) and / or in the longitudinal direction (25).

FIG. 6 shows a longitudinal section of the cylinder-piston unit (111) shown in FIGS. 1 and 7. The hydraulic cylinder-piston unit (111), for example, includes the cylinder the (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 bottom (118). The compensation space (117) is arranged between the Kol ben (115) and the cylinder head (119). In the equalizing space (117) there is also a spring-loaded compensating sealing element (121) which sits sealingly on the piston rod (114). The piston rod (114) penetrates the cylinder head (119). The cylinder (113) as well as 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 formed coaxially with 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 space (117) is then between the piston (115) and the cylinder bottom (118). In this case, the deceleration of the cylinder-piston unit (111) when the piston (115) and the piston rod (114) extend.

When assembling the delay device (21), for example, the cylinder-piston unit (111) is first inserted into the lower housing shell (32). In the carriage (62) which the release lever (82) and the pull pin part (102) is inserted. Both components (82, 102) are each with a

Swivel and slide pins (74, 76) secured. These pivot and slide 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). Then the slide (62) with the components (82, 102) inserted into it is inserted into the lower housing shell (32), so that the pivot and slide pins (74, 76) into the first guide track (43) and the guide pin (107) in the second guide track (44) is used. Here, the piston rod head (112) is inserted into the piston rod head receptacle (63). Finally, the housing (31) is closed by attaching the upper housing shell (33). Another order of assembly is also conceivable.

FIG. 7 shows the delay device (21) when the upper housing shell (33) has been removed in the end position (22) shown in FIG. 1. For example, the delay device (21) is arranged on the furniture body and the driver (2) is arranged 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 push 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 in this position of the acquisition element (61), for example.

When opening the drawer, the driver (2) pulls the driving element (61) relative to the housing (31) in the opening direction (3). The driver (2) lies on the pull pin

part (102). The pull pin part (102) with the pull pin (104) is in the area adjacent to the end position (22) by means of the pivot and slide pins (74, 76) and the guide pin (107) guided in the housing (31) Movement relative to the carriage (62) prevented. Here the

Carriage (62) the piston rod (114) with the piston (115) relative to the cylinder (113) also in this direction. In the case of a cylinder-piston unit (111) with spring return, the carriage (62) can come loose from the piston rod (114) when the carriage (62) moves 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 pulling pin part (102) with the pulling pin (104) pivots through a pivoting angle between

90 degrees and 110 degrees. In the exemplary embodiment, the

Swivel angle 95 degrees. The guide pins (107) dip into the widening (47). In the further process of the driver (2) relative to the delay device (21), the pull pin part (102) is pivoted further. The leader zap

fen (107) migrates into the wedge-shaped receptacle (48). Here it is clamped, for example. The pivot angle of the Zugzap fens (104) is thus limited by means of the wedge-shaped receptacle (48). The guide pins (107) block in this

Parking position (23), cf. Figure 8, a pivoting of the pull pin partly (102) and a method of sledging (62). The actuating arm (85) of the trigger lever (82) can rest on the pull pin part (102).

In the illustration of Figure 8, the driver (2) has left the delay device (21). The driving element (61) is in the non-positive and / or positively secured parking position (23). The drawer can now be opened almost without resistance. The release lever (82) is in a standby position (88). For example, it lies against the carriage (62) with a line of its rear side (89) oriented in the transverse direction (27). The piston rod (114) of the cylinder-piston unit (111) is extended. For example, in a configuration of the cylinder-piston unit (111) 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 parking position shown in FIG

tion (23). The driver (2) moves, for example, above the draw pin part (102) without touching it. When the drawer is closed again, the driver (2) contacts the stop pin (84) of the release lever (82). The release lever (82) is pivoted about the release lever swivel joint (77). Here, the stop pin (84) against the

Push surface (65) of the carriage (62) pressed. The piston rod (114) of the cylinder-piston unit (111) is loaded centrally. In the exemplary embodiment, the side oriented toward the slide (62), for example the underside, of the driver (2) is offset in the direction of the slide (62) at or at the level of the central axis (122) of the cylinder-piston unit (111). 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 pin (107). The guide pin (107) are released from the wedge receptacles (48). The pull pin part (102) leaves the parking position (23), cf. Fi gur 9. In this representation of Figure 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 pin (107) of the pull pin part (102) migrate along the housing-side guide link (55). The pull pin part (102) is pivoted about the pull pin swivel joint (79). Of the

Carriage (62) loads the piston rod (114) of the cylinder-piston unit (111). The piston (115) is retracted and displaces e.g. Oil from the displacement chamber (116) is throttled into the compensation chamber (117). The movement of the entraining element (61) is delayed. Here, the closing movement of the drawer is braked via the driver (2).

FIG. 10 shows the driving element (61) when the drawer is closed further. The driving element (61) coupled to the driver (2) is moved further in the closing direction (4). The piston rod (114) of the cylinder-piston unit (111) is retracted further. The pull pin part (102) is pivoted further in the direction of the operating position (108), in which the pull pin (104) protrudes from the housing (31), cf. Fi gur 7. The guide pins (107) along the inlet slope (49) of the guide link (55) in the direction of the horizontal right portion (51) of the second guide path (44) changed. The further retraction movement of the drawer is further delayed until the driving element (61) has reached the end position (22) shown in FIGS. 1 and 7.

Figures 11 and 12 show a combined acceleration and deceleration device (10) with the housing shell removed (33). In the illustration in FIG. 11, the driving element (61) is in the end position (22). FIG. 12 shows the same combined acceleration and deceleration device (10) with the driving element (61) in the parking position

tion (23). The combined acceleration and deceleration device (10) has an acceleration device (11) and a deceleration device cooperating with it

tion (21). The delay device (21) is largely constructed as described in connection with the embodiment shown in FIGS. 1-10. The GE

However, the housing (31) has additional locating pins (52) for deflecting rollers (53) and a tension element holder (54).

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

The acceleration device (11) can also be used without a train

rope (13) be formed. The spring energy store (15) can then be guided around the deflection rollers (53) or can directly connect the slide (62) to the housing (31). Another arrangement of the acceleration device (11) is conceivable.

It is also conceivable to construct the acceleration device (11) in the form of a block and tackle. Here, for example, in addition to the deflection rollers (53) arranged in the housing (31), a further deflection roller is arranged on the slide (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 Federenergiespei cher (15) is then connected to the traction cable (13). This unit is then placed around the guide rollers (53) and suspended in the carriage (62) and in the housing (31). The tension spring (15) then acts on the slide (62) via the deflection rollers (53). The spring energy store (15) is thus held on the slide (62) and on the housing (31). In the parking position (23), the guide pins (107) lie against the guide link (55). The one carried on the guide pin (107) and oriented parallel to the guide link (55)

Force component of the spring force 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) secure the position of the pull pin part (102) relative to the slide (62) by clamping in the wedge receptacle (48). These two functions can also be realized by means of spatially separated components. For example, as described in connection with the first exemplary embodiment, the position of the pull pin part (102) relative to the slide (62) in the parking position (23) by means of a non-positive and / or positive connection between the pull pin

part (102) and the carriage (62) must be secured.

The driving element (61) is triggered from the parking position (23) as described in connection with the first exemplary embodiment. There is no impact noise. In this case too, the force on the thrust surface (65) is introduced into the cylinder-piston unit (111) without deflection. This prevents damage to the Mitnahmele element (61) and or the housing (31). After the release of the driving element (61) acts both the deceleration force of the delay device (21) and from a relaxing force caused by the relaxing spring energy storage (15) loading force 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 the driving element (61) in a controlled manner into the end position (22). Here it stops without striking. The drawer is now closed, for example. 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 store (15) is loaded. As soon as the driver element (61) has reached the parking position (23), the driver (2) decouples. The drawer can now be opened further.

In Figure 13, a two-part driving element (61) is provided. 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 driving element (61) shown in FIG. 13 has a slide (62) and a double lever (81) pivotably mounted in it. The pivot and slide pins (74, 76) are not shown in this figure 13. The representation of Figure 13 shows the Mitnahmele element (61) in the position of the end position (22).

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

In the second sliding and pivot pin receptacle (68) of the

The double lever (81) is pivotably mounted on the slide (62). The position of the second slide and pivot pin receptacle (68) relative to the thrust surface (65) corresponds, for example, to the conditions of the carriage (62) shown in FIG. 3. In the illustration in FIG. 13, the, for example, oval guide pin (107) lies in a plane parallel to the plane of the slide and pivot pins (74, 76). In this exemplary embodiment too, the guide pin (107) can be designed like the guide pin (107) shown in FIG. 5.

Figure 14 shows the double lever (81) in a Seitenan view. It has a pull pin (104) and a stop pin (84). The pull pin (104) is designed in the same way as the pull pin (104) shown in FIG. Its arrangement relative to the guide pin (107) also corresponds to the ratio sen of the pull pin part (102) shown in FIG.

The stop pin (84) is integrally formed on the pull pin (104). In the exemplary embodiment, the stop pin (84) is connected to the pull pin (104) in the region of the guide pin (107). The stop pin (84) is curved. The imaginary center line of the arc (91) is oriented in the transverse direction (27) and lies in the operating position (108) above the stop pin (84) in the position of the pull pin (104). In this position of the double lever (81), cf. Figure 13, the stop pin (84) is below the carriage (62). At the stop pin (84) is 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.

FIG. 15 shows the entrainment element (61) shown in FIGS. 13 and 14 in the parking position (23) in a housing lower shell (32). The lower housing shell (32) is as constructed as described in connection with the previous examples. The carriage (62) is shown cut along a vertical central longitudinal plane.

The double lever (81) is opposite the end position (22) e.g. pivoted through an angle of 95 degrees. The pivoting direction of the pull pin is oriented in the opening direction (3) when pivoting into the parking position (23). The pull pin (104) in the parking position (23) relative to the carriage (62) has the same position as in the pull pin (104) described in connection with the previous exemplary embodiments. The guide pin (107) are secured in the wedge-shaped receptacles (48) of the second guideways (44). The parking position (23) is thus fixed and the driving element (61) is blocked against displacement in the closing direction (4).

The stop pin (84) projects e.g. out of the slide (62) by a third of its length. It protrudes into the entrainment recess (75). The part of the stop pin (84) protruding from the slide (62) is offset in the direction of the pushing surface (65) from the second pivoting and sliding pin (76).

When moving the driver (2) relative to the Mitnahmele element (61) in the closing direction (4), the driver (2) first contacts the stop pin (84). The double lever (81) experiences a torque around the swivel joint (78) with the second sliding and pivot pin (76). In the representation of Fi gur 15, the double lever (81) is pivoted clockwise. Here, the locking of the double lever (81) is released, for example in the housing (31). The double lever (81) leaves the parking position (23). The Zugzap fen (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 in the carriage (62). The guide pin (107) roll on the guide pillow (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). In this case, the delay 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.
