Description

[Technical Field]

[0001] The present invention relates to a retracting / withdrawing device for sliding doors or drawers, which comprises a housing, in which at least one retracting device with a combined acceleration and deceleration device is arranged, and in which at least one withdrawing device is arranged, the retracting device and the withdrawing device being connectable to each other by at least one switchable axial connection depending on the stroke range, as well as to a door sliding mechanism equipped with such a retracting / withdrawing device and a door guide rail in which the door sliding mechanism is fitted.

[0002] Such a pulling-in and pulling-out device is known from DE 10 2017 004 611 A1, which is suitable for objects with large masses and for large inertial forces.

[0003] The problem underlying the present invention is to develop a compact retracting and withdrawing device with extended applicability.

[0004] This problem is solved by the features of the independent claims. The retraction / retraction device further comprises a second retraction device arranged in the housing. The combined acceleration / deceleration device is part of the first retraction device and also part of the second retraction device.

[0005] The housing of the retracting / withdrawing device includes two retracting devices and at least one withdrawing device. The first retracting device is connected to the withdrawing device by an axial coupling in an end-of-operation position when the withdrawing device is operated from the locked position and when the withdrawing device is moved from the locked position. When the first retracting device is moved to the end-of-operation position, the coupling partners of the axial coupling are disconnected from each other.

[0006] Each of the two retraction devices has one entraining element, which is movable relative to the housing between a stop position and an end position. The two entraining elements are oriented opposite to each other. They share a common combined acceleration / deceleration device. Therefore, the sliding door or drawer can be decelerated to both the closing and opening end positions. For example, from the closing end position, reopening can be activated by applying an external load to the sliding door or drawer in the closing direction. However, the sliding door or drawer can also be pulled directly from this end position in the opening direction (without activating the retraction device).

[0007] Further details of the invention emerge from the subclaims and the following description of schematically illustrated embodiments. [Brief explanation of the drawings]

[0009] Figures 1 to 9 show a combined retractable / withdrawing device 10 and some of its individual parts. Figures 10 to 20 show the individual functional states of the retractable / withdrawing device 10. Such a retractable / withdrawing device 10 is used, inter alia, in a sliding door system 2 or a drawer system.

[0010] When used in a sliding door system (2) (see Figures 22 to 24), the retracting / withdrawing device (10) is, for example, a part of the door slide mechanism (6) attached to the upper surface of the sliding door panel (8). At least one caster (7) of the door slide mechanism (6) is arranged at each end of the retracting / withdrawing device (10) oriented in the longitudinal direction (15). All casters (7) run on door guide rails (3) fixedly arranged in a building or cabinet. At least one fixed follower (5) is arranged on the door guide rail (3), and this follower (5) comes into contact with the retracting / withdrawing device (10).

[0011] It is also conceivable to arrange the retractable / drawing device (10) on the side panel. In this case, the follower (5) is attached to the sliding door panel (8). When used in a drawer system, the retractable / drawing device (10) may be arranged either on the drawer or on the furniture body.

[0012] In a sliding door system (2) consisting of a door guide rail (3) and a door sliding mechanism (6), the entire door sliding mechanism (6) moves inside the door guide rail (3) so that it is not visible from the outside. Here, the door guide rail (3) may have a square or rectangular cross section. In the case of a rectangular cross section, one side length is at most 5% larger than the other side length.

[0013] The retracting / withdrawing device (10) has a housing (11) in which, in the illustrated embodiment, a retracting device (141), a first retracting device (81), and a second retracting device (281) are arranged. The retracting devices (81; 281) and the retracting device (141) shown in the figure are arranged one behind the other in the housing (11). The length of the housing (11) oriented in the longitudinal direction (15) is 420 millimeters in this embodiment. The function of each retracting device (81; 281) is to move the sliding door leaf (8), for example, to a closing end position (301) or to an opening end position (303). When closing the sliding door leaf (8), in this embodiment, the housing (11) is moved relative to the fixed driver (5) in the closing direction (305). In the views of Figures 1, 2 and 10-20, the closing direction (305) is oriented to the left relative to the housing (11), and the opening direction (306) is oriented to the right. Both the opening direction (306) and the closing direction (305) are oriented in the longitudinal direction (15).

[0014] The first retraction device (81) moves the housing (11) in the closing direction (305). The retraction direction (16) of this retraction device (81) relative to the housing (11) is oriented towards the right in these figures. The retraction direction (282) of the second retraction device (281) relative to the housing (11) is oriented in the opposite direction.

[0015] The draw-out device (141) moves the housing (11) in an opening direction (306). The draw-out direction (17) relative to the housing (11) is oriented towards the left in these figures. Both the retraction direction (16; 282) and the draw-out direction (17) are oriented in the longitudinal direction (15).

[0016] Each retraction device (81; 281) has an entrainment element (111; 283) which cooperates with a combined acceleration and deceleration device (82). The combined acceleration and deceleration device (82) has an acceleration device (83) and a deceleration device (91) connected in parallel thereto. The results of the acceleration and deceleration act on the entrainment element (111; 283). The combined acceleration and deceleration device (82) forms the drive of the retraction device (81; 281). In this embodiment, the two retraction devices (81; 281) have the same acceleration device (83) and the same deceleration device (91). The acceleration device (83) is formed by a first spring energy accumulator (83) in the form of a tension spring. This first spring energy accumulator (83) is held by a first spring terminal (84) to the first entraining element (111) and by a second spring terminal (85) to the second entraining element (283).

[0017] The reduction gear (91) has a cylinder-piston unit (92). The cylinder-piston unit (92) has a cylinder (93) and a piston (95) whose position can be adjusted in the cylinder (93) by a piston rod (94). See FIG. 9. The cylinder (93) is supported in the housing (11) so as to be slidable in the longitudinal direction (15). In the views of FIGS. 1 and 2, a first entraining element (111) is rotatably supported on the piston rod (94). A second entraining element (283) is rotatably supported on the cylinder bottom (96).

[0018] The drawer device (141) has a locking lever support part (151) that is movable in the housing (11). A locking lever (171) is supported on the locking lever support part (151) so that it can pivot. A load is applied to the locking lever support part (151) in the drawing direction (17) by a second spring energy accumulator (142). The second spring energy accumulator (142) is the drive part of the drawer device (141). In this embodiment, a second spring end part (143) of the second spring energy accumulator (142) is held in a spring holder (66) on the housing side. The second spring energy accumulator (142) is configured as a tension spring (142). In the view of FIG. 2, the tension spring (142) has two regions (144, 145) with different diameters. In the first region (144) adjacent to the locking lever support part (151), the tension spring (142) has a cross section corresponding to, for example, 0.8% of the length of the housing (11). This region (144) is guided around the deflection pulley (221). The winding angle is 180 degrees in this illustration. The deflection radius in this first region (144) is, for example, three times the diameter of the tension spring (142). In the illustrated embodiment, the diameter of the second region (145) of the tension spring (142) is, for example, more than twice that of the first region (144). Due to its geometrical shape, the second spring energy accumulator (142) has a first region (144) with a high spring stiffness and a second region (145) with a low spring stiffness.

[0019] The housing (11) comprises a first housing shell (31) and a second housing shell (71). The two housing shells are mirror images of each other with respect to the vertical central longitudinal plane of the housing (11). The first housing shell (31) and the second housing shell (71) are connected to each other, for example, by force, form, or material connection. In this embodiment, they are connected to each other by a plurality of screws. The housing (11) is configured in the shape of a parallelepiped. See FIG. 3. The height, oriented perpendicular to the longitudinal direction (15), is, for example, 4.5% of the length, and the depth, oriented perpendicular to the two aforementioned directions, is also, for example, 4.5% of the length. In FIGS. 2 and 10 to 21, the retracting / retracting device (10) is shown without the second housing shell (71).

[0020] The housing (11) has two longitudinal slits (13, 14) in its upper surface (12) separated from each other by a transverse web (22). A locking lever (171) and a first entraining element (111) protrude from the housing (11) through the first longitudinal slit (13), shown on the left in FIGS. 1 and 2. In these figures, the locking lever (171) is in an abutment position (176). Here, the abutment surface (174) of the locking lever (171) is at least approximately perpendicular to the housing upper surface (12). The drawing device (141) is shown in FIGS. 1 and 2 in an intermediate position between the locked position (147) and the ready position (146). The first entraining element (111) is shown in a position between the first entraining element stop position (112) and the first end position (113).

[0021] A second entraining element (283) protrudes from the second longitudinal slit (14) shown on the right in the above-mentioned figures 1 and 2. The second entraining element (283) is shown in the above-mentioned figures in a second entraining element stop position (284), in which the second entraining element (283) is fixed to the housing (11) in a force-locking and / or positive-locking manner.

[0022] Figure 4 shows the inner surface (32) of the first housing shell (31). Figure 5 shows some details in an enlarged view. Together with the inner surface of the second housing shell (71), the housing (11) is configured with four guide lane systems (33, 41, 51, 61). Each guide lane system (33, 41, 51, 61) has two guide lanes (34, 41, 52, 53, 54) facing each other.

[0023] The first guide lane system (33) is configured below the first longitudinal slit (13). This first guide lane system (33) will be referred to as the withdrawal guide lane system (33). Each first guide lane (34) has a straight portion (35), a curved portion (36) adjacent to the straight portion (35), and a locking portion (37) adjacent to the curved portion (36). The length of the first guide lane (34) in the longitudinal direction (15) is, for example, 22% of the length of the housing (11). The first guide lane (34) has a constant height, which in this embodiment is 3 millimeters.

[0024] The curved portion (36) is arranged tangent to the straight portion (35) in the direction of the vertical central cross section of the housing (11). The curve is oriented in the opposite direction to the longitudinal slit (13). The average radius of the curved portion (36) is, for example, 28% greater than the height of the first guide lane (34). The sector angle (38) of the curved portion (36) is 160 degrees in this embodiment. This sector angle (38) is at least 120 degrees. A linearly configured locking portion (37) follows in the region of the sector angle (38). The length of this locking portion (37) corresponds, for example, to half the height of the first guide lane (34).

[0025] In this embodiment, the second guide lane system 41 is disposed at least approximately in the center of the housing 11 in the longitudinal direction 15. This second guide lane system 41 is also referred to below as the first retracting guide lane system 41. Its length is, for example, 22% of the length of the housing 11. The second guide lane system 41 includes, for each housing shell 31, 71, a second guide lane 42 with a horizontal portion 43, an inclined portion 44, and a fixed portion 45. These portions 43, 44, 45 merge with one another. Their height is one-third greater than the height of the first guide lane system 33. The second guide lane system 41 is offset relative to the first guide lane system 33 by 80% of its height toward the first longitudinal slit 13. The distance between the first guide lane system 33 and the second guide lane system 41 in the longitudinal direction 15 is, for example, 2.5% of the length of the housing 11. Here, the shortest distance is formed by the distance between the curved portion 36 and the fixed portion 45.

[0026] The horizontal portion (43) is oriented parallel to the longitudinal direction (15). Its length is, for example, 87% of the length of the second guide lane system (41). The inclined portion (44) forms an angle of, for example, 10 degrees with the longitudinal direction (15). Its length is, for example, 7.5% of the length of the second guide lane system (41). The fixed portion (45) forms an angle of, for example, 80 degrees with the longitudinal direction (15). Its length is, for example, 20% greater than the height of the second guide lane (42). The fixed portion (45) points in the opposite direction to the first longitudinal slit (13).

[0027] The third guide rail system (51) is arranged alongside the second guide rail system (41) on the opposite side of the drawer guide rail system (33) in FIGS. 4 and 5. The third guide rail system (51) is also referred to below as the cylinder guide system (51). The cylinder guide system (51) is configured as a linear guide. The length of the third guide rail system (51) is, for example, 12.5% ​​of the length of the housing (11). The third guide rail system (51) has three guide shells (52, 53, 54) on each housing side. These guide shells (52-54) are congruent with each other in their cross-sections oriented perpendicular to the longitudinal direction (15). The nominal diameters of the guide shells (52-54) correspond to the nominal diameter of the cylinder (93), and the housing (11) forms a loose fit with the cylinder (93).

[0028] The fourth guide lane system (61) is a second retracting guide lane system (61). The second retracting guide lane system (61) is arranged and configured as a mirror image of the first retracting guide lane system (41). The mirror plane is a vertical central cross-section of the cylinder guide system (51). The fourth guide lane system (61) may have, for example, a different length, differently positioned fixing portions, etc., than the second guide lane system (41).

[0029] A spring holder 66 is provided below the fixed part 65 of the second retracting guide system 61. A deflection pulley 221 for the second spring energy accumulator 142 is located in the connecting tenon 23 of the housing 11 in the area of ​​the end of the retracting guide rail system 33 on the door slide mechanism side.

[0030] FIG. 6 shows the entraining elements (111; 283). The two entraining elements (111; 283) are, for example, identically constructed. Each entraining element (111; 283) has a guide tenon (114) on each side and two entraining hooks (116, 117) that define an entraining recess (115). The two entraining hooks (116, 117) are the retracting hook (116) located at the rear in the retracting direction (16) and the push-pull hook (117) located at the front in the retracting direction (16). If necessary, the entraining elements (111; 283) can be partially elastically deformable in the area of ​​the entraining hooks (116, 117). The entraining elements (111; 283) have spring receptacles (118) on their undersides. In this embodiment, the spring receptacles (118) of the two entraining elements (111; 283) hold the first spring energy accumulator (83). On the side opposite the guide tenon (114), the entraining elements (111; 283) have a guide log receptacle (119). The cross-sectional area of ​​the guide log receptacle (119) is defined by a circular section having an angle of, for example, 245 degrees.

[0031] In the illustration of FIG. 2, the guide tenon (114) of the first entraining element (111) is located on the horizontal part (34) of the first retracting guide rail system (41). The guide tenon (114) of the second entraining element (283) is located on the fixed part (65) of the second retracting guide rail system (61). The second guides of the entraining elements (111; 283) are respectively formed by guide logs (97; 98). These guide logs (97; 98) are respectively located in the guide log receiving parts (119) of the entraining elements (111; 283). The guide logs (97; 98) have two guide pins (99), for example, with an oval cross section.

[0032] The guide logs (97, 98) are part of the reduction gear (91). The first guide log (97) is attached to the piston rod head (101) of the piston rod (94) in this embodiment. In the view of FIG. 2, this guide log (97) with its cylindrical central element (102) is located in the guide log receiving portion (119) of the first entraining element (111). See FIG. 9. The second guide log (98) is attached to the cylinder bottom (96) of the cylinder (93). This guide log (98) is pivotally connected to the second entraining element (283).

[0033] 7 shows the carriage (121) of the first retraction device (81). The carriage (121) has a U-shaped groove cross section. The carriage (121) has guide tenons (122, 123) on both sides at both ends. These guide tenons (122, 123) have, for example, an oval cross section. The length of the carriage (121) is, for example, 28% of the length of the housing (11).

[0034] The carriage (121) has a connecting side (124) at its end shown on the left in this figure and a driving side (125) at its other end. The guide tenon (123) at the connecting side (124) is, for example, arranged lower than the guide tenon (122) at the driving side (125). This height difference corresponds to the height difference between the drawer guide system (33) and the first retractable guide system (41). The carriage (121) assembled in the housing (11) is positioned on the retractable guide system (41) by the guide tenon (122) on the driving side and on the drawer guide system (33) by the guide tenon (123) on the connecting side.

[0035] The carriage (121) has a reinforcing rib (126) on each side of its upper surface, which connects the entraining side (125) and the connecting side (124). When the retracting / extruding device (10) is assembled, the reinforcing rib (126) is flush with, for example, the upper surface (12) of the housing (11).

[0036] The two side surfaces (127) of the carriage (121) are congruent with one another. The side surfaces (127) have a load-relief opening (128) and a guide opening (129). For example, two housing screws (21) pass through the carriage (121) in the area of ​​the load-relief opening (128). On the connecting side (124), the load-relief opening (128) is defined by a connecting wall (131). The connecting wall (131) connects the two side surfaces (127).

[0037] In this embodiment, the connecting wall 131 has two connecting surfaces 132 and 133. These connecting surfaces 132 and 133 are arranged one above the other. Hereinafter, the lower connecting surface 132 will be referred to as the operating connecting surface 132. In this embodiment, the operating connecting surface 132 is a uniaxially curved surface that covers an angle of 50 degrees. The radius of the operating connecting surface 132 is, for example, 1.6% of the length of the housing 11.

[0038] The operational coupling surface 132 is continuously transitioned by the coupling wall 131 into another coupling surface 133, namely the load coupling surface 133, which in this embodiment is inclined by 16 degrees relative to a plane normal to the longitudinal direction 15. Here, the end of the load coupling surface 133 adjacent to the reinforcing rib 126 is closer to the guide opening 129 than its end oriented toward the operational coupling surface 132.

[0039] The guide opening (129) is located on the entrainment side (125) of the carriage (121). The guide opening (129) has a cross-sectional area that is at least approximately the shape of an isosceles triangle. The angle between the two equal-length sides (134) is, for example, 10 degrees. Here, the imaginary vertex of this angle is located above the housing (11). The lower side of the guide opening (129) is located below the fixed part (45) of the retractable guide system (41) in the height direction (18) when the carriage (121) is installed. In the view of FIG. 2, the guide tenon (114) of the first entrainment element (111) passes through the guide opening (129) of the carriage (121).

[0040] The carriage 121 has a bottom 135 of plate-like construction, and on the entraining side 125 the carriage 121 has an entraining element recess 136 .

[0041] 8 shows the locking lever support part (151) with the locking lever (171) fitted in it. The locking lever support part (151) has two guide pins (152, 153) on each side. When the locking lever support part (151) is assembled, the guide pins (152, 153) are slidably supported in the drawer guide system (33).

[0042] The locking lever (171) is pivotally supported on the locking lever support part (151). The locking lever (171) is, for example, wedge-shaped. The surface of the locking lever (171) pointing in the retraction direction (16) is the push surface (172). The abutment surface (174) faces the extension direction (17). In the views of FIGS. 2 and 8, the locking lever (171) is at least approximately perpendicular to the connection surfaces of the guide pins (152, 153). In this position, the locking lever (171) is loaded against the pivot abutment by a spring (161), in this embodiment, for example, a helical coil spring (161) in the form of a torsion spring (161). The locking lever (171) can be pivoted from an upright position to at least an approximately horizontal position while being loaded by the spring (161). See FIG. 19. The rotation axis (173) of the locking lever (171) is parallel to the guide pins (152, 153) on both sides.

[0043] The locking lever support part (151) has a spring receiving part (154) at its end pointing in the pulling direction (17), which holds the second energy accumulator (142) in the view of Figure 2. The locking lever support part (151) has an abutment wall (155) below the spring receiving part (154).

[0044] The abutment wall 155 has at least two abutment regions 156, 157. These abutment regions 156, 157 are offset from one another in the height direction 18. In this embodiment, the abutment wall 155 has a lower working region 156, a transition region 158, and an upper load region 157.

[0045] In this embodiment, the actuation area 156 is formed by the lower edge of the abutment wall 155, which may be rounded, for example. In this embodiment, the actuation area 156 is linear. This linear edge is oriented parallel to the center line of the guide pins 152, 153. It is also conceivable that the abutment wall surrounding the actuation area 156 is convex. In this case, the actuation area is reduced to a single point. The transition area 158 may be flat, for example. The transition area 158 is perpendicular, for example, to the plane in which all the guide pins 152, 153 of the locking lever support part 151 are located. The loading area 157 continues from the upper end of the transition area 158. The loading area 157 is inclined, for example, by 10 degrees from bottom to top in the retraction direction 16 relative to the transition area 158. The transitions between the individual areas may be curved.

[0046] The locking lever support part (151) forms two switchable axial connections (211, 212) with the carriage (121). These axial connections (211, 212) are the actuation connection (211) and the load connection (212). The actuation connection (211) is formed when the actuation connection surface (132) of the carriage (121) comes into contact with the actuation area (156) of the locking lever support part (151). The load connection (212) closes when the load area (157) of the locking lever support part (151) comes into contact with the load connection surface (133) of the carriage (121). The two axial connections (211, 212) may be configured as force or positive connections.

[0047] FIG. 9 shows a cylinder-piston unit (92) of a reduction gear (91). The illustrated cylinder-piston unit (92) is a hydraulic cylinder-piston unit (92). It is also conceivable to use a pneumatic cylinder-piston unit (92). The length of the cylinder (93) corresponds, for example, to the length of the carriage (121). The stroke of the piston (95) and piston rod (94) is, for example, 16% of the length of the housing (11). The inner diameter of the cylinder (93) is, for example, 1.5% of the length of the housing (11).

[0048] In the cylinder 93, the piston 95 separates the displacement chamber 103 from the adjustment chamber 104. The adjustment chamber 104 is located on the piston rod side. An adjustment spring 106 is located between the cylinder head 105 and the adjustment chamber 104. The adjustment spring 106 is configured as a compression spring and applies a load to a cylinder disk 107 against which a piston rod seal 108 abuts.

[0049] The displacement chamber 103 is arranged between the piston 95 and the cylinder bottom 96. The piston 95 has, for example, three throttle channels 109 penetrating the piston 95 in the longitudinal direction 15. The throttle channels 109 are covered on the displacement chamber 103 side by, for example, a flexible throttle disc 100. When the piston 95 and the cylinder bottom 96 approach each other, for example, hydraulic oil is throttled and displaced from the displacement chamber 103 into the adjustment chamber 104. In this case, the throttle disc 100 is pressed against the piston 95. When the volume of the adjustment chamber 104 increases, the adjustment spring 106 is compressed.

[0050] When the gap between the piston (95) and the cylinder bottom (96) increases, oil is displaced from the adjusting chamber (104) to the displacement chamber (103). At this time, the throttle disc (100) is lifted, thereby increasing the cross-sectional area of ​​the piston (95). At the same time, the load on the adjusting spring (106) is reduced.

[0051] During assembly, to assemble the door slide mechanism (6) (see Figures 23 and 24), a caster set with one or more casters (7) is attached to both ends of the retractable / retractable device (10). The overall length of the door slide mechanism (6) is, for example, 600 mm or more. The door slide mechanism (6) thus fabricated is inserted into the door guide rail (3). A first follower (5) and, for example, a second follower (9) are arranged on the door guide rail (3) at a distance from each other. The two followers (5, 9) on the side panel are fixed. A sliding door panel (8) is attached to the door slide mechanism (6).

[0052] FIG. 10 shows, for example, the retractable / withdrawable device (10) in the intermediate position of the sliding door. Neither of the drivers (5, 9) is in contact with the retractable / withdrawable device (10). The withdrawable device (141) is in the ready position (146). In this ready position (146), the locking lever support part (151) is located near the end of the drawer guide system (33) pointing in the closing direction (305). The second spring energy accumulator (142) is released to its residual energy value. Furthermore, the torsion spring (161) is released, so that the locking lever (171) is in its pivoted abutment position (176).

[0053] The entraining elements (111, 283) of the two retracting devices (81; 281) are respectively positioned in their entraining element stop positions (112; 284). The first spring energy accumulator (83) of the retracting / extruding device (10) is loaded. The piston rod (94) of the cylinder-piston unit (92) of the reduction gear (91) is extended. The carriage (121) is in contact with the load area (157) of the locking lever support part (151) by means of the second load connection surface (133). The load connection (212) is closed.

[0054] When the sliding door leaf (8) or the drawer is closed in the closing direction (305), the locking lever (171) comes into contact with the first follower (5). See FIG. 11. The locking lever (171) together with the locking lever support part (151) is moved relative to the housing (11) in the retracting direction (16) along the first guide rail system (33). The second spring energy accumulator (142) is tensioned. The locking lever support part (151) moves away from the carriage (121). The load connection (212) is opened. The first retracting device (81) including the carriage (121) remains stationary. The follower element (283) of the second retracting device (281) remains in the second follower element stop position (284).

[0055] Furthermore, when the sliding door is closed, for example manually, the sliding door is further moved relative to the fixed cross plate. The housing (11) is moved in the closing direction (305) relative to the locking lever support part (151), which is held in a fixed position by the driver (5). The second spring energy accumulator (142) is loaded. The locking lever support part (151) runs along the drawer guide system (33). As soon as the front guide pin (152) reaches the curved part (36) of the drawer guide system (33), the locking lever support part (151) rotates relative to the longitudinal direction (15). Further load is applied to the second spring energy accumulator (142) until the front guide tenon (152) passes over the top (39) of the curved part (36). Subsequently, the front guide pin (152) is pulled towards the locking portion (37) while relieving the load on the second spring energy accumulator (142).

[0056] Figure 12 shows the drawer device (141) in the locked position (147). The locking lever (171) has been pivoted together with the locking lever support part (151), and the first guide pin (152) of the locking lever support part (151) is located in the locking part (37) of the drawer guide system (33). The second guide pin (153) remains in the straight part (35) of the drawer guide rail system (33). Both the first retraction device (81) and the second retraction device (281) remain in their fixed positions. The first spring energy accumulator (83) and the second spring energy accumulator (142) are under tension. The first entrainment element (5) moves away from the drawer device (141).

[0057] In the illustration of FIG. 13, the entraining element (111) of the first retracting device (81) abuts against the entraining body (5). The first retracting device (81) is activated. The first entraining element (111) is rotated and grips the fixed entraining body (5) in a positively locking manner. The first spring energy accumulator (83) applies a load to the first entraining element (111), which moves the housing (11) relative to the entraining body (5) toward the closing end position (301). The piston rod (94) of the cylinder-piston unit (92) advances. In this case, the piston (95) compresses the displacement chamber (103) in the cylinder (93), thereby counteracting the acceleration applied by the first spring energy accumulator (83). The carriage (121) is moved in the retracting direction (16) relative to the housing (11). The drawer device (141) remains in its fixed, locked position (147).

[0058] FIG. 14 shows the retracting / withdrawing device (10) in the closing end position (301). The first entraining element (111) has a small residual distance from the end of the horizontal section (43) of the second guide rail system (41) facing away from the withdrawing device (141). The piston rod (94) of the cylinder-piston unit (92) is almost fully extended. The first spring energy accumulator (83) is sufficiently relaxed, and its force in the retracting direction (16) is less than, for example, the static friction force of the retracting device (81) and the sliding door leaf (8). This difference in the aforementioned forces is less than, for example, the spring force of the second spring energy accumulator (142) locked in the locked position (147) and is reduced by the friction force of the withdrawing device (141).

[0059] The drawing-out device (141) is under tension. The carriage (121) is in contact with the locking lever support part (151). The operational connection (211) between the first drawing-out device (81) and the drawing-out device (141) is closed. See the detailed view in Figure 15. The drawing-out device (81) and the drawing-out device (141) are in contact with each other, for example, at the contact line (213). Further movement of the drawing-out device (81) in the drawing-in direction (16) is prevented by the drawing-out device (141). In this embodiment, in the closing end position (301), the sliding door is visually closed for the operator.

[0060] Figure 16 shows the start of the sliding door's opening movement. To do this, the sliding door leaf (8) together with the housing (11) is first pushed, for example manually, from the closing end position (301) in the closing direction (305), for example until a residual play is reached. The housing (11) is loaded relative to the driving element (111) of the retraction device (81), which is secured by the first driving body (5). The first spring energy accumulator (83) is further relieved of its load. At the same time, the housing (11) causes the locked locking lever support part (151) to slide relative to the carriage (121). A thrust force is applied to the locking lever support part (151) via the actuating link (211). The force vector is directed in the longitudinal direction (15). This force vector loads the locking lever support part (151) in the actuation area (156). The force vector of the actuation link loads the locked locking lever support part (151) outside the rectangle spanned by the guide pins (152, 153) in this locked position (147), this force vector being located on the face of said rectangle opposite the locking lever (171).

[0061] The force transmitted through the actuation connection (211) is transmitted to the locking lever support part (151) as a rotational force and a driving force. The locking lever support part (151) is rotated around the current rotation axis by the rotational force as torque from the lever arm and moved in the retraction direction (16). This rotation axis forms the instantaneous rotation center of the actuation movement of the locking lever support part (151). This rotation axis is parallel to the front guide pin (152) and the rear guide pin (152). Here, the first guide tenon (152) moves from the locking part (37) to the curved part (36). As soon as the first guide pin (152) passes over the top (39), the load on the second energy accumulator (142) is relieved. The retraction device (81) unlocks the extraction device (141) by the transmitted force.

[0062] The locking lever support part (151) is loaded by the second spring energy accumulator (142). The actuation connection (211) is released. Subsequently, the load connection (212) is closed. The transition from the actuation connection (211) to the load connection (212) may be continuous.

[0063] FIG. 17 shows the retracting / withdrawing device (10) when the sliding door is opened. The second spring energy accumulator (142) pulls the locking lever support part (151) relative to the housing (11) while reducing its load. The load connection (212) remains closed. This causes the carriage (121) to move relative to the housing (11) by the locking lever support part (151). The carriage (121) pulls the first entraining element (111) along with it, and the first entraining element (111) moves relative to the housing (11) toward its entraining element stop position (112). The first entraining element (111) continues to grip the entraining body (5) so as to surround it. This causes the housing 11 to move in the opening direction 306 relative to the entraining element 111 of the retraction device 81. During this movement of the entraining element 111 relative to the housing 11, the first spring energy accumulator 83 is loaded. At the same time, the piston rod 94 is extended relative to the cylinder 93. Figure 18 shows the closed load connection 212 in detail.

[0064] When moving further in the opening direction (305), the first entraining element (111) pivots onto the fixed part (45). The first entraining element (111) is blocked in the entraining element stop position (112). The first energy accumulator (83) is loaded. The entraining body (5) moves away from the entraining element (111). The sliding door can be opened further manually. The second spring energy accumulator (142) is unloaded to its residual energy value. The carriage (121) limits the further stroke of the locking lever support part (151). The drawer device (81) is under tension. This causes the retraction device (81) to limit the drawer stroke of the drawer device (141).

[0065] Figure 19 shows the retracting / drawing device (10) when the sliding door is further opened. The follower (5) rotates the locking lever (171) relative to the locking lever support part (151) against the force of the torsion spring (161). The retracting device (81) remains unchanged.

[0066] As soon as the follower (5) leaves the locking lever (171), i.e., when the sliding door is opened further, the locking lever (171) rotates open under the force of the torsion spring (161). The retracting / withdrawing device (10) again assumes the starting position shown in Figure 10. Reclosing is carried out as described above.

[0067] The sliding door may be opened without excessive pressure, as described above. Starting from the closing end position (301) shown in FIG. 14, the sliding door together with the housing (11) is pulled in the opening direction (306), for example, manually relative to the door slat. The housing (11) is then pulled in the opening direction (306) relative to the first, temporarily fixed, driving element (111). The operating link (211) is then opened. The drawing device (141) remains in the locked position (147). When the sliding door is to be reclosed, the housing (11) moves relative to the driving element (5), for example, with the drawing device (141) still locked. There is no contact between the driving element (5) and the drawing device (141). As soon as the retracting device (81) is activated, the sliding door is closed again, as described above.

[0068] When the sliding door is only partially open, the retracting / withdrawing device (10) is, for example, located between the positions shown in Figures 16 and 17. To reclose the sliding door, the operator pushes the sliding door in the closing direction (305) against the force of the withdrawing device (141). In doing so, the follower (5) pushes the first follower element (111) toward the end position (113). The follower element (111) pulls the carriage (121), which is additionally loaded in the retracting direction (16) by the retracting device (81). The carriage (121) pushes the locking lever support part (151) together with the locking lever (171) in the retracting direction (16) via the load connection (212). As soon as the first guide pin (152) of the locking lever support part (151) reaches the top (39) of the curved part (36), the locking element support part (151) is fixed in the locked position (147). The entraining element (111) simultaneously reaches the closing end position (301). The sliding door is closed.

[0069] When the sliding door reaches its fully open position, the second entraining element (283) contacts the second entraining body (9) during a portion of the sliding door's stroke adjacent to the end position (303) of the opening movement. The second entraining element (283) leaves its entraining element stop position (284) and is connected to the second entraining body (9) by a positive lock. The combined acceleration / deceleration device (82) influences the movement of the housing (11) relative to the second entraining element (283) by superimposing an acceleration by the first spring energy accumulator (83) and a deceleration by the cylinder-piston unit (92). The sliding door is decelerated and sent to the end position (303) of the opening movement, where it remains stationary without any impact. Figure 20 shows the combined retracting / withdrawing device (10) in this position. The second entraining element (283) is in a second end position (285).

[0070] Figure 21 shows a bidirectional combined retracting / withdrawing device (10). The combined retracting / withdrawing device (10) has a first retracting device (81), a second retracting device (281), a first withdrawing device (141), and a second withdrawing device (341), which are arranged in a common housing (11). Each withdrawing device (141; 341) is associated with a retracting device (81; 281).

[0071] The housing (11) is constructed in a mirror image with respect to a vertical central cross-section, which in this embodiment extends through the center of the cylinder guide system (51). A second drawer guide system (68) is arranged in the housing (11). This guide system (68) is located at the right end of the drawing-in / drawer device (10) in the view of Figure 21.

[0072] The first retracting device (81) is configured as a mirror image of the second retracting device (281). Each of the retracting devices (81; 281) has a driving element (111; 283) and a carriage (121; 321). The carriage (121) of the first retracting device (81) is slidably supported in the first retracting guide system (41) and the first drawer guide system (33). The carriage (321) of the second retracting device (281) is slidably supported in the second retracting guide system (61) and in the second drawer guide system (68). The two retracting devices (81, 281) have a common acceleration device (83) and a common deceleration device (91), which are configured as described in relation to the first embodiment.

[0073] The first drawer device (141) has a first locking lever support part (151) and a first locking lever (171), which are configured as described in relation to the first embodiment.

[0074] The second drawing device (341) has a second locking lever support part (351) and a second locking lever (371). The second locking lever (371) is supported by the second locking lever support part (351) so as to be rotatable relative to the second locking lever support part (351).

[0075] In this embodiment, the two pull-out devices (141, 341) share a common second spring energy accumulator (142). The second spring energy accumulator (142) is deflected around the first deflection pulley (221) and around the second deflection pulley (223) and connects the first locking lever support part (151) and the second locking lever support part (351). The second spring energy accumulator (142) has, for example, three regions with different diameters. In this embodiment, the second region (145) has a diameter twice that of the first region (144) and the third region (148). The first region (144) and the third region (148) are each deflected around one of the deflection pulleys (221; 223). In this embodiment, the winding angle is 180 degrees. The central region (145) has a lower spring stiffness than the two outer regions.

[0076] The opening of the sliding door from the closing end position (301) is performed as described above. Before the sliding door reaches the opening end position (303), the second drawing device (341) is loaded. The second retracting device (281) then moves the sliding door to the opening end position (303). At this opening end position (303), further opening is prevented by the second drawing device (341) and the second carriage (321). When the sliding door is manually pushed further in the opening direction (306), the second drawing device (341) is activated. The sliding door is moved towards the closing position. This is performed in the same way as when the sliding door is moved from the closing end position (301).

[0077] Figure 22 shows an end view of a sliding door system consisting of a door guide rail (3) and a door slide mechanism (6) for a sliding door. The door slide mechanism (6) is completely located on the door guide rail (3). The door guide rail (3) has a square or rectangular cross section, with one side being at most 15% longer than the other.

[0078] Combinations of the individual embodiments are also conceivable. [Explanation of symbols]
