A cylinder-piston unit which can be loaded by means of both driver slides is axially displaceably mounted in the housing. Each driver slide either has a spring mount or is coupled or can be coupled to a spring slide having a spring mount. In addition, a spring energy storage is held in both spring mounts. With the present invention, a compact damping and closing device is developed.

Description

The invention relates to a combined damping and closing device for a center door with a housing in which a driving element can be moved between two parking positions.

From the DE 10 2016 007 885 A1 such a device is known. The driving element can be coupled to a transmission carriage in which a damping device is mounted. When moving the transfer carriage, a spring slide can be coupled to it.

The problem underlying the present invention is to develop a compact damping and closing device.

This problem is solved with the features of the main claim. For this purpose, two driver slides, which can alternatively be positively coupled to the driving element, are each guided between a non-positively and / or positively secured waiting position and a non-positively and / or positively secured end position. A cylinder-piston unit which can be loaded by means of both driver slides is axially displaceably mounted in the housing. Each driver slide either has a spring mount or is coupled or can be coupled to a spring slide having a spring mount. In addition, a spring energy store is held in both spring mounts.

The described combined damping and closing device enables the middle sliding door to be opened from a closed basic position in both directions and to be closed from both directions. In the event of an overload, for example if the door is closed too quickly, the sliding door can open in the other direction. This prevents damage. In an area adjacent to the basic position, a driving element of the damping and closing device is triggered from a parking position when the sliding door is closed. A resultant force from a damping device which retards the closing movement and a force emanating from the spring energy accumulator and accelerating the closing movement promotes the entraining element and the sliding door which can be coupled therewith into the basic position. When opening and closing, the driving element couples with one of the driving slides, depending on the stroke section, while the other in its end position remains. With an opening to the left and a closing from the left, the driver element couples to the left driver slide. With an opening to the right and a closing from the right, the driving element couples with the right driving slide. When moving to the basic position, the two driver slides, together with the discharging spring energy store, load the cylinder-piston unit. The described structure of the combined damping and closing device largely makes it possible to dispense with movement components of the components in directions normal to the longitudinal direction of the damping and closing device. The damping and closing device is thus compact.

The Figure 1 shows a combined damping and closing device (10) for center doors. Devices of this type are used on furniture, for example cupboards, with at least three sliding doors. At least a middle one of these three sliding doors, which is guided, for example, in front of or behind the two outer sliding doors, can be opened from the basic position (11) shown both in an opening direction (2) to the left and in an opening direction (4) to the right. Closing in the closing direction (3; 5) then takes place in the opposite direction. The combined damping and closing device (10) can be arranged on the furniture body or on the sliding door. In operation, it interacts with a driver (6), which is attached to the respective counterpart, either on the sliding door or on the furniture body. The arrangement of the combined damping and closing device (10) on the furniture body, for example on the ceiling of the interior, is described below. For example, it is fastened there by means of two screws which are inserted into through holes (21).

The combined damping and closing device (10) has a housing (20), in which one at least in regions out of the housing (20) projecting driving element (71) is arranged to be displaceable in the longitudinal direction (15). This driving element (71) points in the direction of the closed sliding door, for example, not shown here. It has two catch hooks (82, 282) spaced apart from one another. In the representation of the Figure 1 these driving hooks (82, 282) are symmetrical to a central transverse plane of the combined damping and closing device (10). In this illustration, the two driving hooks (82, 282) each have a hook surface (83, 283). The two hook surfaces (83, 283) are parallel to one another in the basic position (11) of the driving element (71). The length of the combined damping and closing device (10) is 270 millimeters in this exemplary embodiment. Their height in the height direction (14) including the parts of the driving element (71) protruding from the housing (20) is, for example, 30 millimeters. The height of the housing (20) is 24 millimeters. The width of the combined damping and closing device (10) is determined by the width of the housing (20). In the exemplary embodiment, this is 12 millimeters.

The housing (20) consists of a lower housing part (31) and an upper housing part (61). Both parts enclose a housing interior (22). The upper housing part (61) overlaps with corresponding webs of the lower housing part (31), at least in regions, with end webs (62). The lower housing part (31) and the upper housing part (61) are joined together. For example, the two parts (31, 61) are screwed, glued or welded together. The housing (20) has a longitudinal slot (24) on one longitudinal end face, through which the housing interior (22) is connected to the surroundings (1). The longitudinal slot (24) has a rectangular cross-sectional area. The length of the longitudinal slot oriented in the longitudinal direction (15) (24) is 88% of the length of the housing (20) in the exemplary embodiment. The width of the longitudinal slot is, for example, 45% of the width of the housing (20). The catch hooks (82, 282) protrude into the surroundings (1) through this longitudinal slot (24).

On its side surface (25), the housing (20) has two slot-like guide grooves (32, 42) arranged symmetrically to the central transverse plane both on the lower housing part (31) and on the upper housing part (61). These guide grooves (32, 42) each have a straight guide groove section (33, 43) oriented in the longitudinal direction (15). The guide grooves (32, 42) are shown at both ends in the illustration of FIG Figure 1 turned down. At the end facing the central transverse plane, the respective end section (34; 44) encloses an angle of, for example, 90 degrees with the straight guide track section (33; 43). At the end facing away from the central transverse plane, the individual guide groove (32; 42) has a waiting section (35; 45). This includes an angle of, for example, 105 degrees with the straight guide groove section (33; 43). The waiting section (35; 45) is, for example, twice as long as the end section (34; 44). A first driver slide guide pin (102; 302) is mounted in each case in the straight guide groove section (33; 43) of the guide grooves (32: 42). In the end section (34; 44) of the guide grooves (32; 42) there is a second driving slide guide pin (103; 303). The driver slide guide pins (102, 103; 302, 303) mounted in one of the guide grooves (32; 42) are together on a driver slide (101; 301), cf. Figure 23 arranged.

The housing (10) can also be designed in such a way that the guide grooves (32; 42) designed here as openings are sunk into the housing inner wall (26). You are then not visible from the outside of the housing (10).

The Figures 2-16 show a combined damping and closing device (10) with removed housing upper part (61) and its individual parts. It comprises a driving element (71) arranged in the lower housing part (31), two driving slides (101, 301), a cylinder-piston unit (141) and a spring energy accumulator (161). In the representation of the Figure 2 the driving element (71) is in a middle position. This position is referred to below as the basic position (11) of the combined damping and closing device (10). In this exemplary embodiment, the spring energy store (161) is designed as a tension spring (161).

The lower housing part (31) has a side wall (36), the inside of which is delimited by end webs (37) which are approximately normal to the side wall (36). In the exemplary embodiment, the end webs (37) enclose an angle of 2 degrees with a normal plane to the side wall (36). The width of the end webs (37) normal to the side wall (36) corresponds to the width of the housing interior (22). They are offset inwards by their width from the contour of the side wall (36). In the area of the longitudinal slot (24), the end webs (36) are replaced by a ceiling web (38). Its width is, for example, a quarter of the width of the end webs (37).

A control track (46) is arranged in the side wall (36) below the longitudinal slot (24). The length of the control track (46) in the longitudinal direction (15) is, for example, 84% of the length of the lower housing part (31). The control track (46) has a straight control section (47) oriented in the longitudinal direction (15), at the two ends of which a parking section (48; 49) projects in the direction facing away from the longitudinal slot (24). In the exemplary embodiment, the individual parking section (48; 49) closes with the straight control section (47) an angle of 90 degrees. The respective transitions between the individual parking section (48; 49) and the straight control section (47) are curved. The angle enclosed by the parking section (48; 49) and the straight control section (47) can also be larger, for example 135 degrees. The control track (46) is surrounded, for example, by a limiting web (39) projecting into the housing interior (22). The width of this boundary web (39) is, for example, one millimeter.

The illustration of FIG. 1 shows normal and symmetrical to the central transverse plane of the damping and closing device (10) Figure 3 a spacer web (51) is arranged below the straight control section (47). When the housing (20) is assembled, it secures the distance between the side wall (36) of the lower housing part (31) and the side wall of the upper housing part (61) in the housing interior (22). In the exemplary embodiment, a slide channel (52) adjoins the spacer web (51). The slide channel (52) is oriented in the longitudinal direction (15). It has a constant, bowl-shaped cross section and is open on one side. For example, their radius is 4 millimeters. The length of the slide channel (52) is, for example, 32% of the length of the housing (20). On its other side, the slide channel (52) is delimited by a head shell (53). The length of the head shell (53) is 4% of the length of the housing (20) in the exemplary embodiment. It has a constant cross section, which is smaller than the cross section of the slide channel (52). The imaginary center lines of the slide channel (52) and the head shell (53) are aligned with one another. The group of the slide channel (52) and the head shell (53) is arranged symmetrically to the central transverse plane of the combined damping and closing device (10).

In the longitudinal direction (15), the guide grooves (32, 42) are arranged in front of and behind the group of slide channel (52) and head shell (53). The guide grooves (32, 42) are thus each between the group mentioned and the end wall (27) delimiting the combined damping and closing device (10) in the longitudinal direction (15). The waiting sections (35, 45) of the guide grooves (32, 42) are bent in the same direction as the parking sections (48, 49) of the control track (46). For example, the waiting sections (35, 45) are shown in FIG Figure 2 delegated below the park sections (48, 49). In this exemplary embodiment, the respective end section (34; 44) forms an angle of, for example, 115 degrees with the straight guide groove section (33; 43) at the end facing the central transverse plane. At the end facing away from the central transverse plane, the individual guide groove (32; 42) has a waiting section (35; 45). This includes an angle of, for example, 100 degrees with the straight guide groove section (33; 43). The guide grooves (32; 42) are delimited on the side of the housing interior (22), for example by means of an edge web (54). Its width is, for example, one millimeter.

The control track (46) and the guide grooves (32, 42) can be designed as control links and guide links. Here, for example, is only that in the representation of the Figure 2 the lower limit of the grooves (32, 42, 46) is designed as a sliding surface.

The Figure 4 shows the driving element (71). The driving element (71) in the exemplary embodiment consists of two hook slides (81, 281) and a connecting rod (72) arranged between them. Each of the hook slides (81; 281) has a driving hook (82; 282). The hook slides (81; 281) arranged at both ends of the connecting rod (72) are pivotally connected to the connecting rod (72). In this exemplary embodiment, the swivel joint is formed in each case by a swivel pin (73; 74) arranged on the connecting rod (72), each of which is in a swivel bushing (84; 284) of the hook slide (81; 281), cf. Figure 5 , is stored. The pivot pin (73; 74) projects from the hook slide (81; 281) on both sides, for example. The length of the connecting rod (72) is, for example, 36% of the length of the combined damping and closing device (10).

The driving element (71) can also be formed in one piece. In this case the hook slides (81; 281) are e.g. rigidly and immovably connected to the connecting rod (72). An embodiment of the driving element (71) with film joints between the hook slides (81; 281) and the connecting rod (72) is also conceivable.

In the Figures 5 and 6 the hook slide (81; 281) is shown as an individual part in two isometric views. The two hook slides (81; 281) are identical to one another in the exemplary embodiment. The individual hook pusher (81; 281) comprises the catch hook (82; 282) and a hook pusher body (85). The driving hook (82; 282) is, for example, web-like. In the exemplary embodiment shown, it is integrally formed on the hook slide body (85). The hook surface (83; 283) is aligned in the representations, for example, normal to the surface (86) of the hook slide body (85).

The hook pusher body (85) has a prism-shaped support body (87) adjoining its surface (86), which sits on a main body (88). The latter has, at least approximately, a cuboidal envelope contour. He has on both sides each have a cylindrical control pin (89). A plane spanned by the center lines of the control pins (89) and the pivot bushing (84; 284) is, for example, normal to the plane of the hook surface (83; 283).

On the underside (91) of the hook slide body (85) has a coupling pin (92) in the exemplary embodiment. This has, for example, a rectangular cross-sectional area. It merges laterally into two side webs (93) which delimit the hook pusher body (85) in the width direction (29). The height of the coupling pin (92) is three millimeters in the exemplary embodiment. The coupling pin (92) has two coupling surfaces (94, 95) pointing in the longitudinal direction and facing away from one another. A first coupling surface (94) is oriented in the direction facing the catch hook (82; 282). A second coupling surface (95) points in the direction of the swivel bushing (84; 284). In the exemplary embodiment, both coupling surfaces (94, 95) are formed parallel to one another. For example, they are each normal to a plane that is spanned by the center lines of the control pins (89) and the swivel bushing (84, 284). The first coupling surface (94) is from said normal plane e.g. spaced apart by 3.3% of the distance between said center lines in the direction of the hook-side end face (96). The second coupling surface (95) is in the exemplary embodiment from a normal plane containing the center lines of the control pins (89) to the plane spanned by the center lines of the control pins (89) and the pivot bushing (84, 284) by a third of the distance of the center lines in the direction of the Swivel bushing (84; 284) offset.

One of the coupling surfaces (94; 95) or both coupling surfaces (94, 95) can be curved. For example, the single coupling surface (94; 95) can be convex, uniaxial curved surface. The arch axis then runs in the width direction (29). Both coupling surfaces (94, 95) can also be designed as single-axis concave or as double-axis curved surfaces. They can be spaced apart from one another up to the length of the hook slide (81; 281). The coupling pin (92) can also be constructed from two, for example parallel, webs which are spaced apart from one another in the longitudinal direction of the hook slide (81; 281).

The Figures 7 and 8 show a driver slide (101; 301). The two driver slides (101, 301) of the combined damping and closing device (10) are identical. The individual driver slide (101; 301) has a driver slide body (104) which has two driver slide guide pins (102, 103; 302, 303) on each of its two side surfaces (105). All driver slide guide pins (102, 103, 302, 303) are cylindrical in the exemplary embodiment. They have the same length and the same diameter. The distance between the center lines of the driver slide guide pins (102, 103; 302, 303) of a driver slide (101; 301) is, for example, 80% of the distance between the center lines of the control pins (89) and the center line of the swivel bushing (84; 284).

The driver slide (101; 301) has a stop face (106) on one end face, which, when the driver slide (101; 301) is installed, points in the direction of the central transverse plane of the damping and closing device (10). This is prism-shaped in cross section with rounded transitions. It has three partial areas arranged one above the other (107 - 109). In the exemplary embodiment, the upper two partial surfaces (107, 108) adjoin one another in a transition radius. The middle partial surface (108) is normal to one of the center lines of the driver slide guide pins (102, 103; 302, 303) spanned level. The upper partial surface (107) deviates from the plane of the central partial surface (108) by an angle of 20 degrees. The transition between the central partial surface (108) and the lower partial surface (109) is also rounded. The lower partial surface (109) encloses an angle of 27 degrees with the plane of the central partial surface (108). The imaginary intersection of the planes of the central partial surface (108) and the lower partial surface (109) lies below the plane spanned by the central lines of the driving slide guide pins (102, 103; 302, 303). The imaginary line of intersection of the plane of the lower partial surface (109) and the plane of the upper partial surface (107) lies outside the driver slide (101; 301). The end face (111) of the driver slide (101; 301) facing away from the stop face (106) is designed as a flat face in the exemplary embodiment.

The driver slide (101; 301) has a coupling recess (112) on its upper side. The length of this coupling recess (112) in the longitudinal direction is, for example, 11% greater than the length of the coupling pin (92). The depth of the coupling recess (112) is, for example, two thirds of the height of the coupling pin (92). The width of the coupling recess (112) is slightly smaller than the distance between the side webs (93) of the hook slide (81; 281). The coupling recess (112) is delimited in the longitudinal direction by means of two slide surfaces (113, 114) pointing towards each other. In the exemplary embodiment, both slide surfaces (113, 114) are designed as flat surfaces and are arranged parallel to one another. They are normal to the plane spanned by the center lines of the driving slide guide pins (102, 103; 302, 303). The distance between the plane of the second slide surface (114) and the center line of the guide pins (103; 303) adjacent to the stop surface (106) is, for example, 58% of the distance between the center lines both guide pins (102, 103; 302, 303). In the exemplary embodiment, the center line of the guide pins (102; 302) lies in the plane of the first slide surface (113).

The two slide surfaces (113, 114) can be curved in one or more axes. For example, they can be concavely curved in one axis.

The driver slide (101; 301) has a spring holder (116) on its underside (115). This comprises a retaining web (117) with a central receiving groove (118) and a securing hook (119). The spring holder (116) is arranged on the end of the driver slide (101; 301) facing the stop surface (106).

The Figure 9 shows a longitudinal section of a cylinder-piston unit (141). The cylinder-piston unit (141) comprises a cylinder (142) in which a piston (144) connected to a piston rod (143) can be moved linearly. In the representation of the Figure 9 the piston rod (143) is retracted. The piston (144) is in its left end position. A return spring (146) which is supported on the closed cylinder base (145) and on the piston (144), for example, is compressed. This return spring (146) is a compression spring in the exemplary embodiment. The displacement space (147) located between the piston (144) and the cylinder base (145) has its minimum volume. The piston (144) has throttle channels (148) oriented in the longitudinal direction (15), through which, when the piston (144) moves in the direction of the cylinder head (149), hydraulic oil, for example, from a between the cylinder head (149) and the piston (144 ) lying compensation chamber (151) can flow into the displacement chamber (147) while simultaneously moving a throttle disc (152). The piston (144) can be sealed against the cylinder inner wall (153). On the piston peripheral surface (154) and / or further throttle channels can also be formed on the cylinder inner wall (153).

The compensation space (151) is delimited by a compensation sealing element (155). This compensation sealing element (155) is by means of e.g. compensating spring (156) designed as a compression spring is supported on the cylinder head (149). It is sealed both on the piston rod (143) and on the inside wall of the cylinder (153).

The piston rod (143) penetrates the cylinder head gasket (157) and has a piston rod head (158) located outside the cylinder (142). The cylinder-piston unit (141) can also be pneumatic. For example, the compensating sealing element (155) and the compensating spring (156) can be omitted. The compensation chamber (151) can have a pneumatic connection to the housing interior (22) at least in a stroke end position.

When assembling the combined damping and closing device (10), the driver slides (101, 301) are inserted into the guideways (32, 42) of the lower housing part (31), for example. The pre-assembled driver element (71) is used in such a way that the control pins (89) and the pivot pins (73, 74) lie in the control track (46). For example, the driving element (71) can be inserted into the center of the control track (46). The cylinder-piston unit (141) is inserted between the driver slides (101, 301). In addition, the spring energy storage device (161) is hooked into the two spring receptacles (116), for example by applying a preload. Both driver slides (101, 301) are moved, for example, into their end positions (17; 19). The cylinder-piston unit (141) is then retracted The distance between the spring mounts (116) is minimal. The housing (20) is then closed by fitting the housing cover (61). This assembly can be done, for example, using a template.

The assembled damping and closing device (10) is e.g. attached to the ceiling of a furniture body. At the middle, e.g. a driver (6) is attached to the inner sliding door.

The Figure 2 shows the combined damping and closing device (10) in the basic position (11). The sliding door is closed. The driving element (71) is located in the center of the straight control section (47) of the control track (46). The hook slides (81, 281) are, for example, without contact with the driving slides (101; 301) which are in their respective end positions (17; 19), cf. Figure 10 , In this end position (17; 19) the driver slides (101; 301) are non-positively and / or positively secured. For example, the plane of the driver slide guide pins (102, 103; 302, 303) includes an angle of 13 degrees with the longitudinal direction (15). The tension spring (161) is relaxed except for the preload. It has its minimum operating length. The cylinder-piston unit (141) is retracted. It also has its shortest operating length. It lies in the representation of the Figure 2 with the cylinder bottom (145) on the first driver slide (101) and with the cylinder head (149) on the second driver slide (301). Here, the cylinder-piston unit (141) contacts the upper partial surface (107) of the stop surface (106).

If the middle sliding door from the representation of the Figure 2 Opened to the right in the opening direction (4), the driver (6) moves the driver element (71) to the right. Like the partial sectional view of the Figure 11 shows, contact the first coupling surface (94) of the coupling pin (92) of the second hook slide (281) the first slide surface (113) of the coupling recess (112) of the second driver slide (301). The second driver slide (301) is pivoted about the first guide pin (302) displaced along the guide groove (42). The second guide pin (303) enters the straight guide groove section (43). The Indian Figure 2 The first driver slide (101) shown on the left remains in its end position (17). The tension spring (161) is tensioned. The piston rod head (158) migrates along the stop surface (106) into the second partial surface (108). The piston rod (143) is extended by means of the return spring (146).

The Figure 12 shows a partial sectional view of the second hook slide (281) and the second driver slide (301) during the further movement in the opening direction (4) to the right. The hook slide (281) continues to rest with its first coupling surface (94) on the first slide surface (113). The driver slide (301) is shifted to the right along the guideway (42). The first driver slide (101) remains in its end position (17). The tension spring (161) is tensioned. The piston rod (143) of the cylinder-piston unit (141) extends. Depending on the opening speed of the sliding door, the piston rod head (158) can detach from the driving slide (301).

When the opening movement continues to the right, the driving element (71) with the two hook slides (81, 281) is moved further to the right. With its first coupling surface (94), the right hook slide (281) presses the second driver slide (301) further to the right. Here, the first guide pin (302) of the driver slide (301) enters the Transition arch to the waiting section (45). This is shown in FIG. 13. The first guide pin (302) is in this - non-stationary - representation at the apex of the transition arch. For example, the tension spring (161) is stretched to its maximum operating length in this position. The hook slide (281) continues to push the coupling recess (112) of the driving slide (301) to the right. At the same time, the relaxing tension spring (161) loads the driving slide (301) with a torque around the second guide pin (303). The driver slide (301) is pulled into the second waiting position (18) by means of the tension spring (161), cf. the Figures 14 and 15 , The angle of the driver slide (301) relative to the longitudinal direction (15) is, for example, 21 degrees in the waiting position. There it remains firmly and / or positively secured. The hook slide (281) - and thus the driving element (71) - and the driving slide (301) are coupled to one another, for example, during the entire movement. The second hook slide (281) is displaced with its control pin (89) into the curve of the control track (46) and into the second parking section (49). In this case, the coupling pin (92) is immersed, for example, with play on all sides in the coupling recess (112) of the second driver slide (301). The catch hook (282) of the second hook slide (281) plunges into the envelope contour of the housing (20). The driving element (71) is now in a second parking position (13). In this second parking position (13), it can be secured non-positively and / or positively, for example by means of the second driver slide (301). However, it is also conceivable that the driving element (71) in the parking position (13) is decoupled from the driving slide (301) standing in the waiting position (18).

In this second parking position (13) of the driving element (71), the first hook slide (81) is in the straight control section (47) of the control track (46). The spring energy store (161) is charged, the stored energy being less than the maximum operating energy. The cylinder-piston unit (141) is extended. In the representation of the Figure 15 the cylinder-piston unit (141) continues to rest with the cylinder base (145) on the upper partial surface (107) of the stop surface (106) of the first driver slide (101). The first driver slide (101) is still in its end position (17). The piston rod (143) loaded by means of the return spring (146) is supported on the lower partial surface (109) of the stop surface (106) of the second driver slide (301).

The sliding door can now be opened further to the right. The combined damping and closing device (10) remains in its position. The driver (6) is then completely separated from the driver element (71).

When the sliding door is closed in the closing direction (5) from the right, the driver (6) passes the second hook slide (281) without contact. The damping and closing device (10) is in its Figure 15 shown location. When the sliding door is closed further, the driver (6) strikes the first hook slide (81) of the driver element (71). The first hook slide (81) is moved to the left. He takes the second hook pusher (281) with him via the connecting rod (72).

The second hook pusher (281) is pulled along the control path (46). The second hook pusher (281) pivots about the pivot pin (74) guided in the control track (46). The second hook pusher (281) hits with his second coupling surface (95) to the second slide surface (114) of the second driver slide (301). The second driver slide (301) is taken along. The first driver slide (101) remains at rest. The piston rod (143) of the cylinder-piston unit (141) is retracted relative to the cylinder (142). Oil, for example, is pressed out of the displacement space (147) through the throttle channels (148) into the compensation space (151). The movement of the driver slides (101, 301) towards one another is delayed. The movement of the sliding door is dampened. At the same time, the relaxing spring energy store (161) loads the two driver slides (101, 301) with respect to one another with a tensile force. A resulting force from the spring force and the damping force thus acts on the sliding door. A quickly closed sliding door is braked.

Together with the second hook slide (281), the second driver slide (301) is pivoted into the horizontal position. The first hook pusher (81) pulls the second hook pusher (281) along the control path (46) analogously to the illustration of FIG Figure 12 , The second driver slide (301) is pulled along. The piston rod (143) of the cylinder-piston unit (141) now rests on the central partial surface (108) of the stop surface (106). The piston rod (143) is retracted further. The spring energy accumulator (161), which continues to relax, acts on the entraining element (71) via the entraining slide (301). The sliding door is further braked, for example to a residual speed.

When approaching the inner end of the guideway (42), the second guide pin (303) of the driver slide (301) swings into the end section (44). This movement is supported by the hook slide (281). The contact zone of the piston rod head (158) and the stop surface (106) moves in the first partial area (107). The piston rod (143) pushes the driving element (301) into the end position (19). The hook pusher (281) detaches from the driver pusher (301). The tension spring (161), which relaxes to the minimum operating length, pulls the sliding door into the Figure 2 shown closed position.

The manual or motorized opening of the sliding door in an opening direction (2) to the left is carried out analogously. The piston rod head (158) and the piston rod (143) keep their position relative to the housing (20) and the second driver slide (301). The cylinder (142) slides to the left along the slide channel (52). If the sliding door is opened quickly, the cylinder base (145) can temporarily detach itself from the first driving element (101). The Figure 16 shows the combined damping and closing device (10) with the driving element (71) in the left parking position (12), the first parking position (12). The first driver slide (101) is in the first waiting position (16). The piston rod (143) of the cylinder-piston unit (141) is extended and lies against the first partial surface (107) of the stop surface (106) of the second driver slide (301). This second driver slide (302) is in the end position (19). With the cylinder bottom (145), the cylinder-piston unit (141) bears against the third partial surface (109) of the stop surface (106) of the first driver slide (101). This is also pressed into the waiting position (16). The swivel angle of the driver slide (101; 301) in the waiting position (16; 18) relative to the longitudinal direction (15) of the combined damping and closing device (10) is greater than the swivel angle of the other driver element (301; 101) relative to the Longitudinal direction (15) in the respective end position (19; 17). The spring energy storage (161) is charged.

Closing in a closing direction (3) from the left is analogous to closing the sliding door that is open to the right. The combined damping and closing device (10) then takes its in again Figure 2 shown starting position.

If the sliding door is closed too quickly, for example, it may still be too high in the basic position (11). It then continues in the other opening direction (2; 4). The driving element (71) releases the respective driving slide (101; 301) from its end position (17; 19) and moves it in the opening direction (2; 4). At the same time, the tension spring (161) is tensioned. After the sliding door has come to a standstill, it is pulled back into the basic position (11) by means of the tension spring (161).

When the sliding door is partially opened, it is stopped, for example, when the driving element (71) is in a position between the basic position (11) and one of the parking positions (12; 13). The piston rod (143) extends out of the cylinder (142) in some areas. The tension spring (161) is loaded to a value between its minimum operating voltage and its maximum operating voltage. For example, when the sliding door is released, the relaxing tension spring (161) pulls the sliding door back into the in the Figure 2 shown basic position (11).

Before the sliding door is closed for the first time after assembly, the combined damping and closing device (10) is in the basic position (11), for example. When closing, the sliding door contacts one of the catch hooks (82; 282) from the outside and deforms it elastically. After passing the driver (6), the driver hook (82; 282) returns to its original shape. The driver (6) now sits between the catch hook (82; 282). It is also conceivable to bring the combined damping and closing device (10) into a parking position (12; 13) before the sliding door is closed for the first time.

The Figures 17-30 show further views and details of the in the Figure 1 shown damping and closing device (10). In the Figure 17 The damping and closing device (10) is shown in the basic position (11) with the upper housing part (61) removed. A driving element (71) is guided in the lower housing part (31) between two parking positions (12, 13). Depending on its stroke range, this driving element (71) can be coupled relative to the basic position (11) with a first driving slide (101) or with a second driving slide (301). A cylinder-piston unit (141) with an extendable piston rod (143) and a cylinder (142) displaceable in the longitudinal direction (15) relative to the housing (20) is arranged between the two driver slides (101, 301). The cylinder-piston unit (141) is constructed as in connection with that in connection with the Figures 2-16 described embodiment described. Each of the driver slides (101; 301) is coupled to a spring slide (131; 331). The two spring slides (131; 331) can each be moved along a linear path (55; 56) in the housing (20).

The Figure 18 shows the lower housing part (31) of the combined damping and closing device (10) shown in FIG. The control path (46) adjacent to the longitudinal slot (24) also has a straight control section (47) in this exemplary embodiment, to which a parking section (48; 49) is connected on both sides. The angle enclosed by the respective parking section (48; 49) and the straight section (47) is 120 degrees in this exemplary embodiment. The transition between the individual parking section (48; 49) and the straight section (47) is curved. The length of the control track (46) in this exemplary embodiment is 87% of the length of the housing (20). The two parking sections (48; 49) are at least triangular in the exemplary embodiment. The imaginary angle at the end of the park section (48; 49) is, for example, 37 degrees.

The group of slide channel (52) and head shell (53) for the cylinder-piston unit (141) is designed as described in connection with the first embodiment. It is arranged centrally to the central transverse plane of the combined damping and closing device (10).

The two guide grooves (32, 42) are arranged in the lower housing part (31) axisymmetrically to the central transverse plane. They each have an outside waiting section (35; 45), a straight guide groove section (33; 43) and an end section (34; 44) facing the slide channel (52). The distance in the height direction (14) between the horizontal center lines of the control track (46) and the guide grooves (32, 42) is, for example, 35% of the height of the housing (20). The length of a single guide groove (32, 42) is, for example, 22% of the length of the housing (20).

A linear path (55, 56) is arranged on the side of the guide grooves (32, 42) facing away from the control path (46). This is formed horizontally and arranged parallel to the straight section (33; 43) of the guideways (32; 42) and to the straight section (47) of the control track (46). The length of the linear tracks (55; 56) is 22% of the length of the housing (20). The distance from the straight section (33, 43) of the guide grooves (32; 42) is 34% of the height of the housing (20) in the exemplary embodiment. The linear tracks (55; 56) are each offset to the outside by 2% of the length of the housing in relation to the guide grooves (32; 42).

In the Figure 19 the upper housing part (61) is shown. The end webs (62) are flush with the outer contour of the side wall (66). The upper housing part (61) can thus overlap the end webs (37) of the lower housing part (31) by means of its end webs (62). A control track (46), a group of slide channel (52) and head receptacle (53), two guide grooves (32, 42) and two linear tracks (55, 56) are arranged on the inner wall of the upper housing part (61). When the housing (20) is mounted, these are arranged in a mirror image of one another with respect to a vertical center longitudinal plane of the damping and closing device (10).

The Figure 20 shows the driving element (71) in the Figures 1 and 17 shown variant of the damping and closing device (10). This driving element (71) also comprises a connecting rod (72), at the two ends of which a hook slide (81; 281) is articulated. In this exemplary embodiment, a joint pin (75) penetrates the control bolt (97) facing the connecting rod (72) and the connecting rod (72). The two hook slides (81, 281) are, for example, identical to one another.

In the Figures 21 and 22 a hook pusher (81; 281) is shown in two isometric views from below. The hook pusher (81; 281) has a hook pusher body (85), on the two side surfaces of which a control pin (89) and a control pin (97) are arranged. These control pins (89) and control pins (97) each have a cylindrical cross section. The distance between their center lines is, for example, 6.5% of the length of the damping and closing device (10).

The catch hook (82; 282) protrudes from the hook slide body (85) at the top. It has a hook surface (83; 283) which lies in a normal plane to a plane spanned by the control pins (89) and control bolts (97). The driving hook (82; 282) can also be designed to be elastically deformable in this exemplary embodiment.

The hook pusher body (85) has a coupling pin (92) on its underside (91). This is formed by the side webs (93) and two transverse webs (98, 99) spaced apart from one another in the longitudinal direction of the hook slide (81; 281). The first transverse web (98) facing the catch hook (82; 282) has a first coupling surface (94). The second crossbar (99) facing the connecting rod (72) has a second coupling surface (95). The two coupling surfaces (94, 95) point in opposite directions. They are arranged parallel to each other. In the exemplary embodiment, their distance is 3% of the length of the control track (46).

The Figures 23 and 24 show a driver slide (101; 301) of the in the Figures 1 and 17 illustrated embodiment. This comprises a driving slide body (104), on each of which two driving slide guide pins (102, 103; 302; 303) are arranged on both sides. On its upper side, the driving slide body (104) has a coupling recess (112) which is delimited by two slide surfaces (113, 114). The distance between the two mutually parallel, mutually facing slide surfaces (113, 114) is, for example, three tenths of a millimeter larger than the distance between the coupling surfaces (94, 95).

The driving slide (101; 301) also has a stop surface (106) facing the central transverse plane of the combined damping and closing device (10). This is designed, for example, as the stop surface (106) of the in the Figures 2-16 illustrated embodiment.

The driver slide (101; 301) has a hook recess (121) on its underside (115). This points in the direction facing away from the stop surface (106). The hook recess (121) has a pointed counter hook (122). The counter hook surface (123), cf. Figure 26 , includes, for example, an angle of 30 degrees with a plane spanned by the center lines of the guide pins (102, 103; 302, 303)).

In the Figure 25 a spring slide (131; 331) is shown. The individual spring slide (131; 331) has two slide pins (133, 134) on each of its two side surfaces (132). In the exemplary embodiment, all slide pins (133, 134) have an oval cross section. The spring slide (131; 331) has an engagement hook (136) on its upper side (135). When the spring slide (131; 331) is installed, it points in the direction of the central transverse plane of the combined damping and closing device (10). The engagement hook (136) is delimited by an outer hook surface (137) and an inner hook surface (138). The two hook surfaces (137, 138) enclose an angle of, for example, 27 degrees. The angle enclosed by the outer hook surface (137) and the plane spanned by the slide pins (133, 134) is 24 degrees in the exemplary embodiment.

The spring slide (131; 331) has a spring holder (116) on its underside facing away from the engagement hook (136). This is designed, for example, like the spring holder (116) of in connection with that in the Figures 2-16 described embodiment.

The assembly of the in the Figures 1 and 17-30 Combined damping and closing device (10) described takes place analogously to the assembly of the in the Figures 2-16 illustrated embodiment. In addition, a spring slide (131; 331) is inserted into each of the linear tracks (55; 56). The engagement hook (136) of the respective spring slide (131; 331) is inserted into the hook recess (121) of the driver slide (101; 301). The spring energy store (161) is inserted into the spring receptacles (116) of the spring slides (131, 331). In this exemplary embodiment too, the spring energy store (161) is designed as a tension spring (161).

In the Figures 1 and 17 the combined damping and closing device (10) is in its basic position (11). For example, the sliding door is closed. Both driver slides (101, 301) are in a respective end position (17; 19). Each spring slide (131; 331) engages with its engagement hook (136) in a hook recess (121) of the associated driver slide (101; 301). The cylinder-piston unit (141) also pushes the driver slides (101, 301) into their end positions (17; 19). The tension spring (161) has its shortest operating length. The Figure 26 shows a partial longitudinal section of the hook slide (81), the driver slide (101) and the spring slide (131) in the lower housing part (31) in this position. The sectional plane is, for example, a vertical central longitudinal plane of the combined damping and closing device (10). In this basic position (11), the hook slide (81) is in the straight control section (47) of the control track (46). For example, it is spaced from the driving slide (101), for example by a few tenths of a millimeter.

When opening the sliding door in the opening direction (2) to the left, the driver (6) pulls the driver element (71) to the left. The left hook slide (81) releases the driver slide (101) from the end position (17). The coupling recess (112) engages around the coupling pin (92). The driver slide (101) is released from the end position (17) and moves along the straight guide groove section (33), cf. Figure 27. The driver slide (101) also pulls the spring slide (131) in the opening direction (2). The tension spring (161) is tensioned. Here it is drawn linearly. The cylinder (142) of the cylinder-piston unit (141) slides along the slide channel (52) in the opening direction (2). Here, the contact of the cylinder base (145) on the driver slide (101) can come loose. The second driver slide (301) and the second spring slide (331) remain in the end position (19).

In the Figures 28 and 29 is the combined damping and closing device (10) from the Figure 17 shown with an opening to the left. The driving element (71) is in the first parking position (12). Like the partial longitudinal section of the Figure 28 shows, the coupling pin (92) of the hook slide (81) sits in the coupling recess (112) of the driving slide (101). The spring slide (131) engages with the engagement hook (136) in the hook recess (121) of the driver slide (101). The tension spring (161) is stretched to its greatest operating length. It is linearly stretched. It therefore does not require any additional installation space below the spring slide (131, 331). In addition, the cylinder-piston unit (141) loads both driver slides (101, 301). The driver slide (101) is thus positively and non-positively secured in the first waiting position (16). This securing also holds the driving element (71) in the first parking position (12).

When the sliding door is closed in a closing direction (3) from the left, the driver (6) strikes the second hook slide (281) of the driver element (71). The driving element (71) is released from the parking position (12). It takes the first driver slide (101) with it, on which the tensile force of the relaxing tension spring (161) acts. At the same time, the cylinder-piston unit (141) is retracted, thereby delaying the movement of the sliding door. When the basic position (11) is reached, the driver slide (101) and the spring slide (131) coupled to it move into the first end position (17). The driving element (71) detaches from the driving slide (101). The sliding door remains in the basic position (11).

For example, if the sliding door closes quickly, the spring slide (131; 331) can detach from the driver slide (101; 301). The piston (144), which moves relative to the cylinder (142), decelerates the sliding door. The relaxing tension spring (161) pulls the two spring slides (131, 331) together relative to each other until the contact of each spring slide (131; 331) with a driver slide (101; 301) is restored.

The opening of the sliding door in the opening direction (4) to the right and the closing of the sliding door in the closing direction (5) from the right is carried out analogously. The Figure 30 shows the combined damping and closing device (10) with the driving element (71) in the right parking position (13).

If the sliding door closes very quickly, the sliding door can also open in the other direction in this exemplary embodiment.

The driver slide (101; 301) and the spring slide (131; 331) can be coupled by means of a joint. This joint can be a swivel joint or a combined swivel and push joint. If necessary, the driver slide (101; 301) can also be connected to the spring slide (131; 331) by means of a film joint.

In all exemplary embodiments, the piston rod head (158) can additionally be guided axially in the housing (20). This guide is oriented in the longitudinal direction (15). This prevents the piston rod from bending.

It is also conceivable to couple the cylinder-piston unit (141) to a driver slide (101; 301) or to both driver slides (101, 301). For example, the piston rod head (158) is mounted in a curved elongated hole in the second driver slide (301). In this case too, the piston rod head (158) can additionally be guided in the housing (20). The cylinder base (145) can then be pivotally and displaceably mounted in a curved slot of the first driver slide (101). When the cylinder-piston unit (141) is coupled to the driver slides (101, 301) on both sides, the cylinder-piston unit (141) can be designed without a return spring (146).

Combinations of the individual exemplary embodiments are also conceivable.
