The invention relates to a device for moving two relatively movable furniture parts in an adjacent to an operating end position of the relative movement stroke section, wherein the device is a movement in the direction of the operating end position under discharge of a repeatedly loadable first energy storage controlling retraction device and the movement in the operating end facing away Direction controlling extractor having a repeatable loading and unloading second energy storage.

From DE 10 2010 061 483 AI a piece of furniture with a collection device and with a separately arranged here extracting device is known. During assembly, a complex tuning of both devices is required.

The device DE 198 23 305 AI requires two schubla- denseitige driver, one of which can be coupled with a collection device and the other with a pull-out device. Also in this case, the adjustment and alignment of the two devices to each other in the finished furniture part.

The present invention has for its object to develop a device that is easy and easy to install on a piece of furniture. This problem is solved with the features of the main claim. For this purpose, the device has a housing which guides both the collection device and the extension device. The extension device can be coupled to the intake device within the housing by means of a clutch, so that a discharge of the second energy store controls the loading of the first energy store.

In this device, the collection device and the extension device are decoupled from each other in the process in the direction of the operating end position. First, the second Energiespei- rather, so the energy storage of the extension device, charged. The charged second energy storage can be releasably locked. Subsequently, the collection device is actuated, the energy storage, hereinafter referred to as the first energy storage, is initially charged. The intake device can in this case have a combined acceleration and deceleration device.

In order to move the device parts relative to one another in the opposite direction, the collection device and the withdrawal device are coupled together. An optionally existing locking of the extension device is achieved here. The discharge of the second energy store causes a process of the device parts in the direction away from the operating end position. At the same time, the first energy supply will be recharged. After charging the first energy storage, the collection device can be releasably locked. This device can be mounted as a whole with its housing on furniture ^¬ piece. So that the assembly time of the furniture ^¬ tee is reduced. Further details of the invention will be apparent from the dependent claims and the following description ^¬ schematically illustrated embodiments.

FIG. 1 shows a combined draw-in and pull-out device (10). Such devices (10) are used in pieces of furniture with two relatively movable Möbelstücktei len to move them relative to each other, for example in the direction of a closed end position and in the closed end position facing away. The two relative to each other movable furniture pieces are, for example, a Mö belkorpus and a drawer or a sliding door, which are linearly movable between an open and a closed position. The device (10) can be either angeord net either on the furniture body or on the drawer or the sliding door. At the respective other piece of furniture then a driver (5), see. Figures 2 and 14-23 arranged, the one in an operating end position (19) adjacent partial stroke of the furniture piece parts to each other, the combined retraction and extraction device (10) contacted and operated. The mentioned operating end position (19) can be a closed or an open operating end position. For these operating end positions, for example, the two pieces of furniture are still displaceable in the direction of, for example, a stop, by one or two millimeters. It is also conceivable to arrange the two pieces of furniture pivotally to each other. For example, then both the combined intake and extraction device (10) and the driver (5) are arranged in the interior of a cabinet.

The combined pull-in and pull-out device (10) has a housing (11) which consists of a housing lower part (31) and a housing cover (71). The lower housing part (31) and the housing cover (71) are, for example, positively, positively or materially connected. In the exemplary embodiment, they are screwed by means of seven screws (21). The housing (11) is cuboidal. Its length oriented in the longitudinal direction (15) is, for example

304 mm. The normal oriented height is

21% of the length and the depth 5% of the length. At the upper side (12), the housing (11) has two longitudinal slots (13, 14) spaced from one another by a transverse web (22). By the first, in the illustration of Figure 1 arranged on the right longitudinal slot (13) projects a Mitnähmeelement (111) out of the housing (11). This entrainment element (111) is part of a collection device (81) arranged in the housing (11), cf. Figure 2. In the illustrations of Figures 1 and 2, the entrainment member (111) is in a pivoted position at the left end of the longitudinal slot (13). The driving element (111) is in a driving element parking position (112). Through the left longitudinal slot (14) protrudes in the above representations, a locking lever (171) in the environment (1). This latching lever (171) is part of a pull-out device (141) guided in the housing (11). In the illustrations of Figures 1 and 2, the locking lever (171) is at least approximately perpendicular to the top (12) of the housing (11) at the left end of the second longitudinal slot (14). In the following, the device (10) is described in use in an adjacent to the closed end position partial stroke of a movable relative to a furniture body drawer. In the illustration of FIG. 1, the drawer, not shown here, is extended. The device (10) is attached to the furniture body. At the drawer of the driver (5) is arranged.

FIG. 2 shows the device shown in FIG. 1 with the housing cover (71) removed. In the initial position shown, the feed direction (16) oriented in the direction of the closed end position points to the right. this is the

Closing direction (16) of the furniture. The extension direction (17) facing away from the end position, which corresponds to the opening direction (17), points to the left. Both the opening direction (17) and the closing direction (16) are oriented in the longitudinal direction (15) of the device (10).

The intake device (81) comprises a combined acceleration and deceleration device (82), a guide spout (91) and a coupling carriage (131). It is guided in the housing (11) by means of a first guideway system (23). In the illustration of Figure 2 as a tension spring (83) formed first energy storage (83) of the device (10) is loaded. The entrainment element (111) is positively and / or positively secured in the entrainment element.

Parking position (112). The piston rod (85) of a cylinder-piston unit (84) is extended.

The pull-out device (141) comprises a second energy store (142) which is held on the housing (11) and on a latching lever carrier part (151). The detent lever support part (151) supports the detent lever (171). The pull-out device (141) is guided in the housing (11) by means of a second housing-side guideway system (24). In the illustration of Figure 2 is the second energy accumulator (142) of the device (10) formed as a tension spring (142) is deflected by two deflection rollers (221) and unloaded, for example, to a residual tension value. FIG. 3 shows the inside of the housing lower part (31). In the figure 4, the housing cover (71) is shown unfolded for this purpose, so that in this figure 4, the upper housing side (12) is below. The first guideway system (23) comprises guideways (32) which are arranged opposite one another in the housing lower part (31) and in the housing cover (71) when the housing (11) is mounted. The respective guide track (32) is arranged adjacent to the first longitudinal slot (13). It comprises a straight guide track section (33) oriented in the longitudinal direction (15) and a holding section (34) oriented, for example, normally in the direction away from the longitudinal slot (13). In this case, the holding section (34) is connected to the end of the straight guideway section (33) facing the second guideway system (24) via a transitional bend (35).

The first guide track (32) can also be designed as a guide slot.

In FIG. 3, a piston rod system (53), a spring receiver (54) and a spring holder receiver (55) are arranged on the right in the lower housing part (31). In the assembled state, cf. 2, the piston rod system (53) supports the piston rod (85) of, for example, the hydraulic cylinder-piston unit (84). This cylinder-piston unit (84) is part of the acceleration and deceleration device (82) of the intake device (81). When using a pneumatic cylinder-piston unit (84), the piston rod system (53) may be formed as a piston rod receptacle. The spring receiver (54) receives the first energy store (83). In the exemplary embodiment, the first energy store (83) is a tension spring (83), one end of which is held in the spring receptacle (54) and the other end in the guide carriage (91) of the retraction device (81).

Adjacent to the second longitudinal slot (14), the second guide rail system (24) is arranged. This comprises one each in the housing lower part (31) and in the housing cover (71) arranged guide groove (58). It has a longitudinal direction (15) oriented straight Führungsnutabschnitt (59). At this the first guideway system (23) facing the end of a short Führungsnutabschnitt (61) is connected. In the exemplary embodiment, this short guide groove section (61) forms an angle of 85 degrees with the straight guide groove section (59). The transition between the straight guide groove portion (59) and the short guide groove portion (61) is rounded. The short guide groove portion (61) opens e.g. centrally in a release section (62). This is oriented parallel to the straight Führungsnutabschnit (59). Its length is, for example, 4% of the length of the straight Führungsnutab- cut (59).

A connecting portion (63) of the second guide rail system (24) connects the release portion (62) with the straight guide groove portion (59). This connecting section (63) encloses an angle of, for example, 30 degrees with the longitudinal direction (15).

Parallel to the release portion (62) has two sliding portions (36, 37) are arranged. They are both in the longitudinal direction (15) and offset in the height direction (18) to each other. Both sliding portions (36, 37) have the same length. This is, for example, 50% greater than the length of the release section (62).

In the illustration of Figure 3 below and in the illustration of Figure 4 above the second guide rail system (24) each have a coupling rail (65) is arranged. Furthermore, in the longitudinal slots (13, 14) facing away from a receiving space (64) for the guide carriage (91) imprinted.

The lower housing part (31) and the upper housing part (71) each have e.g. groove-shaped rack mount (38). In this example, a slot-like housing aperture (39) is arranged. Both at the outside of the housing lower part (31) directed towards the surroundings (1) and the outside of the housing cover (71) oriented towards the surroundings (1), a minus sign (41) is attached to the end of the housing aperture (39) oriented in the closing direction (16) ) eg imprinted. The other end of the housing breakthrough (39) is for example marked with a plus sign (42).

In addition to the rack mount (38), both housing parts (31, 71) have an opening (43) with a square cross-sectional area. The edge length of the square is for example 12 millimeters.

On the in the opening direction (17) oriented portion of the housing (11) receiving pin (44) for receiving the deflecting rollers (221) are arranged. Between the Aufnähmeza fen (44) and in the opening direction (17) oriented housing (45) on the housing bottom part (31) a pivot pin (46) for receiving a pivoting beam (182) is arranged. Farther sits in this area of the housing base (31) a Federhaiterung (56).

In the figure 5, the guide carriage (91) is shown. It comprises a carriage support (92), two Mitnahmeelementauf- _\ measures (93), a spring retainer (94), a cylinder housing (95) and a Wälzradaufnahme (96). The carriage carrier (92) has a cuboid envelope contour. His in the

For example, longitudinal (15) oriented length is seven times greater than its height.

The driving element receptacles (93) are web-like out of the carriage carrier (92). They are congruent to one another and have, for example, a distance of three millimeters from one another. The driving element receptacles (93) each have a long hole-like opening (98). This is executed bent, wherein the center of the imaginary arc in the opening direction (17) offset from the driving element receiving (93). In this breakthrough (98), the carrier element (111) is guided when the device is mounted.

At the bottom of the slide carrier (92), the spring holder (94) is arranged. This comprises a in the closing direction (16) open receiving channel (99) with a retaining ring. When mounted device (10) in the spring holder (94) of the first energy storage (83) is held.

Laterally on the carriage carrier (92), the cylinder housing (95) is formed. This has, for example, in a plane normal to the longitudinal direction (15) has a U-shaped cross section. Retaining elements (102) hold the cylinder (86) of the cylinder-piston unit (84) when the device (10) is mounted. The in the opening direction (17) pointing end of the carriage carrier (92) is fork-shaped with two forks (103). In the fork tines (103) the Wälzradaufnahmen (96) are congruent to one another.

FIG. 6 shows the rolling wheel (201) used in the exemplary embodiment in the Wälzradaufnahme (96). The Wälzrad (201) is a straight spur gear with double-sided journals (202). For example, it has 20 teeth. In the mounted state, the rolling gear (201) meshes with a rack element (241) and with the coupling carriage (131). The teeth of all these Wälzgetriebeteile (201, 131, 241) has the same module. In the figure 7, the coupling carriage (131) is shown. He has on both sides each have a rail receptacle (132) with which the coupling carriage (131) in the coupling rails (65) of the housing (11) can be guided. In the illustrations of Figures 2 and 7, the coupling carriage (131) has on its underside a rack (133). On the side facing away from the toothed rack (133), the coupling carriage (131) has a coupling surface (134). This is normal to the longitudinal direction (15) and is oriented in the closing direction (16). Between the rack (133) and the coupling surface (134) penetrates a spring recess (135) the coupling cuts (131). For example, on one side of the coupling carriage (131) has a rod recess (136).

In the figure 8, the entrainment element (111) is shown. It has on both sides in each case two guide pins (113, 114) and two entrainment recess (115) delimiting driving hooks (116, 117). The guide pins (113) situated in the front in the closing direction (16) are seated in the illustration of FIG. 2 in the straight track section (33). The other guide pin (114) penetrate the second opening (98) of the driving element receiving (93) and sit in the representation of Figure 2 in the holding portion (34). The two driving hooks (116, 117) are in the closing direction (16) rear laying retractable hook (116) and one of the closing direction (16) front lying pressure and Auszugs hook (117). Optionally, the driving element (111) in the region of the driving hooks (116, 117) may be formed partially elastically deformable.

FIG. 9 shows a toothed rack element (241). It has a straight gearing (243). The toothed rack element (241) designed as a rolling-element part has a screw-head receiving means (244) in which the head of a connecting screw (233) of an adjusting device (231) is mounted. This can be actuated by means of an adjusting wheel (232) projecting through the aperture (43). On its longitudinal sides, the rack member (241) has guide rails (245). Indicating pins (242) are arranged in the guide strips and project through the housing openings (39) when the device (10) is mounted. Optionally, the rack member (241) may also be integrated into the lower housing part (31).

FIG. 10 shows the latching lever carrier part (151). This has two fork-like arranged, mutually parallel retaining bracket (152, 153), each having an opening (154). Another breakthrough (155) penetrates the locking lever support member (151) in the area oriented in the opening direction (17). At the end pointing in the opening direction (17), the latching lever carrier part (151) has a spring receptacle (158). In this spring receptacle (158) in the illustration of Figure 2, the second energy storage (142) is held. FIG. 11 shows the locking lever (171). This is wedge-shaped and has a bolt receptacle (173). His in the closing direction (16) facing surface is an abutment surface (172). In the opening direction (17) shows a stop surface (174).

FIG. 12 shows a longitudinal section of the latching lever carrier part (151) with latching lever (171) inserted therein. The locking lever carrier part (151) points with a coupling stop (159) in the opening direction (17). The coupling stop (159) is formed in this embodiment as uniaxially curved surface. But it can also be curved convex or have a flat surface. Together with the coupling carriage (131), the locking lever carrier part (151) in the representation of FIG. 2 forms a switchable axial coupling (211). This coupling (211) may be formed non-positively or positively.

A pivot pin (161) penetrates the opening (155) of the locking lever support part (151). In the mounted state, it protrudes into the guide groove (58) of the second guideway system (24). Furthermore, a guide pin (162) penetrates the detent lever support part (151) in the opening (154) and the detent lever (171) in the bolt receptacle (173) seated between the retaining brackets (152, 153). Also, the guide pin (162) protrudes when mounted device (10) in the guide groove (58). A pivot stop (157) of the locking lever support part (151) limits the pivot angle of the locking lever (171). In the exemplary embodiment, the maximum pivot angle is 67 degrees. Parallel to the guide pin (162), between the detent lever guide member (151) and the detent lever (171) is a cylindrical screw torsion spring (163), e.g. arranged in the form of a leg spring (163). A first leg (164) of this

Leg spring (163) rests on the detent lever support member (151) from. The second leg (164) abuts on the latching lever (171), so that the latching lever (171) is loaded in the direction of a vertical position. A pivot stop (175) prevents the locking lever (171) from tipping over.

FIG. 13 shows a wedge slide (191). This has two guide pins (193, 194), with which it sits in the mounted state in the sliding portions (36, 37) of the housing (11). The wedge slide is U-shaped in a front view and has two by means of a connecting bracket (192) connected side bars (195). At the side of the side webs (195) facing away from the connecting bracket (192), these each have a guide bevel (196). The angle enclosed by the guide slopes (196) with the longitudinal direction (15) corresponds to the angle which the connecting section (63) encloses with the longitudinal direction (15). In this case, in the exemplary embodiment, the guide slope (196) increases from the side pointing in the closing direction (16) to the side pointing in the opening direction (17). The illustrated wedge slide (191) further has on its in the opening direction (17) facing side two insertion tabs (197). However, it can also be designed without these insertion tabs (197).

In the illustration of FIG. 2, the wedge slide (191) is connected to the pivot lever (182) by means of a transmission rod (183). The pivot lever (182) is mounted on the pivot pin (46). Furthermore, it is loaded by means of a housing (31) in the spring holder (56) held tension spring (181).

When assembling the device (10), for example, the entrainment member (111), the Wälzrad (201) and the cylinder-piston unit (84) in the guide carriage (91) are used. In addition, the first tension spring (83) in the guide spout (91) and in the lower housing part (31) is attached. In the lower housing part (31) of the coupling slide (131) and the rack member (241) are further used so that the toothed rod (133) and the toothing (243) with the Wälzrad (201) mesh. The coupling carriage (131), the Wälzrad (201) and the rack member (241) thus form the Wälzgetriebe (120). The detent lever (171) and the leg spring (163) are inserted into the detent lever support member (151). The second tension spring (142) is also used together with the spring holder (222) in the lower housing part (31) and deflected around the example provided with damping rings pulleys (221). The second tension spring (142) is guided through the spring recess (135) of the coupling carriage (131) and fastened to the spring receptacle (158) of the detent lever carrier part (151). The latching lever carrier part (151) is inserted into the housing (11) such that the coupling stop (159) in the closing direction (16) lies in front of the coupling surface (134) of the coupling carriage (131).

Now the wedge slide (191), the pivot lever (182), the transmission rod (183) and the tension spring (181) can be used. Here, for example, the transmission rod (183) without contact in the rod recess (136) of the coupling carriage (131). Finally, the housing cover (71) can be placed and secured. The assembly can also be done in a different order.

The device (10) mounted in this way is fastened, for example, to the body of a piece of furniture. At the example, relatively movable drawer, for example, a rod-like design driver (5) is arranged. The driver (5) can be formed also U-shaped, for example, two rods in the longitudinal direction (15) are offset from each other.

In this case, only one-time alignment of the driver (5) to the entrainment element (111) and to the detent lever (171) is required. When the drawer is open, cf. Figure 2, the driver (5) in the opening direction (17) is offset from the locking lever (171). The second energy store (142), the tension spring (181) and the leg spring (163) are relieved. The first energy store (83) is loaded. In FIGS. 2 and 14-23, the device (10) is shown without the housing cover (71).

When closing the drawer, the driver (5) contacts the locking lever (171), cf. Figure 14. The locking lever (171) is moved in the closing direction (16) along the guide groove (58). The locking lever (171) in this case takes the locking lever carrier part (151), so that the second tension spring (142) is tensioned. The detent lever support member (151) detaches from the coupling carriage (131). The collection device (81) remains at rest.

FIG. 15 shows the device (10) with the driver (5) still retracted. The latching lever (171) and the latching lever support part (151) are pivoted, wherein the guide pin (162) of the latching lever (171) sits in the short, bent part (61) of the guide groove (58). For example, the guide pin (162) contacts the wedge slide (191). The collection device (81) remains in its position. The first tension spring (83) and the second tension spring (142) are tensioned. The pull-out device (141) and the pull-in device (81) are locked.

In the figure 16 is shown as a detail, the locking position (66) of the extension device (141). The guide pin (162) is in the short Führungsnutanschnitt (61) and is there clamped by means of the wedge slide (191).

In the illustration of FIG. 17, the driver (5) has triggered the feed device (81). The driving element (111) is swung open. The first tension spring (83) loads via the guide carriage (91) the catch element (111), which conveys the catch (5) in the direction of the closed operating end position (19). The piston rod (85) of the cylinder-piston unit (84) is retracted. Here, in the cylinder (86), a piston attached to the piston rod (85) compresses a displacement space, so that the acceleration applied by means of the tension spring (83) counteracts a deceleration. The guide carriage (91) and the coupling carriage (131) are moved in the closing direction (16). The extension device (141) remains in its locked position (66).

Figure 18 shows the device (10) in an e.g. closed operating end position (19). The carrier element (111) has a small residual distance from the end of the straight guide track section (33) facing away from the housing wall (45). The piston rod (85) of the cylinder-piston unit (84) is almost completely retracted. The first tension spring (83) is largely relaxed with its force in the closing direction (16) e.g. smaller than the static friction force of the feeder (81) and the drawer.

The extension device (141) is stretched. The coupling slide (131) has a small distance to the catch lever carrier part (151). For example, this distance is less than three millimeters. In the embodiment, the drawer is now closed. FIG. 19 shows the beginning of the opening movement of the drawer. For this purpose, first the drawer of the operating end position (19) in the closing direction (16) is pressed until, for example, the residual play is used up.

The guide carriage (91) pulls the coupling slide (131) in the closing direction (16) by means of the rolling gear (120). Due to the ratio of the Wälzgetriebes (120), the stroke of the coupling carriage (131) is twice as large as the path of the guide carriage (91). The coupling carriage (131) couples by means of the coupling (211) with the pull-out guide support member (151). The coupling surface (134) abuts against the coupling stop (159). The coupling carriage (131) pushes the pullout guide support part (151) in the closing direction (16), so that the guide pin (162) displaces the wedge slide (191) in the opening direction (17), cf. Figure 20. The guide pin (162) is displaced under load of the wedge slide (191) in the release portion (62). The pullout guide support member (151) is released from the lock. The movement of the wedge slide (191) is transmitted by means of the transmission rod (183) on the pivot lever (182). This pivots in the illustration of Figure 19 counterclockwise about the pivot pin (46). Figure 21 shows the device (10) when pulling out the drawer. The second energy store (142) discharges and pulls the latching lever carrier part (151) and the latching lever (171) in the opening direction (17). The guide pin (162) moves along the release section (62). By means of the clutch (211), the clutch spout (131) is pushed in the opening direction (17). The coupled via the Wälzgetriebe (120) guide carriage (91) pulls the driving element (111) and the drawer-side driver (5) also in this direction. At the same time, the guide carriage (91) loads the first energy store (83) that is being charged. Due to the ratio of the Wälzgetriebes (120), the tensile force of the second energy storage (142), for example between 75% and 150% of the power of the first energy store (83) amount. Thus, a secure opening of the drawer is guaranteed even with existing friction. Thus, the discharge of the second energy store (142) controls the loading of the first energy store (83). The piston rod (85) of the cylinder-piston unit (84) is extended, for example, spring-loaded.

FIG. 22 shows the further opening. The guide pin (162) moves along the connecting portion (63). The wedge slide (191) is further loaded in the opening direction (17). The tension spring (181) is tensioned.

In the further process in the opening direction (17), the carrier element (111) pivots into the holding section (34). The entraining element (111) is blocked in the entraining element parking position (112). The first energy store (83) is then charged.

In the figure 23, the device (10) is shown at more open drawer. The driver (5) has pivoted the detent lever (171) counter to the force of the leg spring (163) relative to the detent lever carrier part (151). The second energy store (142) is discharged to a residual voltage. The collection device (81) is stretched.

As soon as the driver (5) has left the latching lever (171), ie the drawer is further opened, the tension of the leg spring (163) causes the latching lever (171) to swing open. The device (10) now assumes again the starting position shown in FIG. The re-closing occurs as described above. In the illustrated embodiment, the stroke of the extension device (141) in the longitudinal direction (15) is greater than the stroke of the collection device (81) in the same direction. The ratio of the strokes corresponds to the gear ratio of the Wälzgetriebes (120).

If the drawer is opened only incompletely, the device (10) stands, for example, between the positions shown in FIGS. 22 and 23. When closing the

Drawer pushes the drawer against the force of the extension device (141) in the closing direction (16).

Here, the driver (5) pushes the entrainment element (111) in the direction of the operating end position (19). The entrainment element (111) pulls in the guide carriage (91) additionally loaded in the closing direction (16) by means of the draw-in device (81). About the Wälzgetriebe (120) of the coupling carriage (131) is also pulled in the closing direction (16). The axial coupling (211) closes and the coupling carriage (131) pushes the locking lever support member (151) together with the locking lever (171) also in the closing direction (16). As soon as the guide pin (162) reaches the short guide groove section (61), the catch element carrier part (151) is secured in the locking position (66). At the same time, the carrier element (111) has reached the operating end position (19). The drawer is closed.

For example, after installation of the device (10) in a piece of furniture, the operating end position (19) of the two relatively movable parts can be adjusted. For this purpose is For example, by means of the adjusting wheel (232) of the adjusting device (231), the toothed rack element (241) is displaced in the longitudinal direction (15). The movement of the indicator pin (242) in the direction of the minus sign (41) causes the entraining element (111) to move in the closing direction (16). When turning the adjusting wheel (232) of the display pin (242) in the direction of the plus sign (42), moves the Mitnähmeelement (111) in the opening direction (17). Thus, the operating end position (19) of the device (10) is adjustable.

Combinations of the individual embodiments are conceivable.
