Description

The invention relates to a Einziehsystem for a plurality of extendable furniture parts, each extendable in a pull-out of a furniture body and in a pull-out direction in the furniture body are inserted, comprising for each of the extendable furniture parts Einzieheinheit, each acted upon by a collection spring Retractable part, which is adjustable by a mitbewegten when pulling out the pull-out furniture part with the pull-out furniture part between a basic position, which occupies the Einziehteil in the retracted state of auszieharen furniture part, and a waiting position in which the driver decouples when pulling out the pull-out furniture part from Einziehteil , And has a Einziehteil between the basic position and the waiting position adjustable storage bearing unit, wherein the Einziehsystem comprises at least one attachable to the furniture body mounting rail, which a plurality of assembly stations a ufweist, wherein in each case one of the bearing units can be fastened to a respective mounting position and for this purpose has a respective mounting place at least one mounting element for fastening the bearing unit to the mounting rail.

Furniture with several extendable furniture parts, usually in the form of superimposed drawers, are often equipped with a Einziehsystem. This includes Einzieheinheiten (also called Selbsteinzüge or feed mechanisms) for each of the pull-out furniture parts that automatically move this when inserting the pull-out furniture part over a final section of the Einfahrweges and so ensure the fully retracted state of the pull-out furniture part. Such Einzieheinheiten are known in different embodiments. For example, goes from the AT 401334 B a feed mechanism out, in which a displaceable against the force of a spring tilting slide is present. The tilt slide is on one in the Extraction direction of the drawer against the force of the spring linearly displaceable carriage arranged tiltable about a tilting axis. At the time of the AT 393948 B Known Einzieheinheit is also a tilt slide available, which is displaceable along a guideway against the force of a spring. The guideway has a straight portion and a bent portion, which causes the pivoting of the tilting slide about an imaginary tilting axis in its tilted end position.

Today, self-feeds are usually equipped with insert dampers to dampen the retraction of the pull-out furniture part in the last section of the Einfahrweges. Such a damped retraction device, in which the tilting slide cooperates with a insertion damper, is for example from EP 1 532 892 A1 known. The spring-loaded tilt slide cooperates here with a linear damper in the form of a piston-cylinder unit, which in particular acts pneumatically. Even damped by means of rotary dampers Selbsteinzüge are known.

From the EP 1 500 763 A2 there is a self-closing mechanism combined with a pull-out device. By Ausziehsperrvorrichtungen a simultaneous withdrawal of two or more coupled by the pull-out device with each other furniture parts, such as superimposed drawers, prevented. The extendable furniture parts are therefore only alternately extendable. A central locking is often realized on such Ausziehsperrvorrichtungen. In a conventional embodiment locking rods are present, which have only a limited space for their displacement. For each extendable furniture part an actuating part is provided, which cooperates with at least one of the locking rods. When you take off one of the extendable furniture parts at least one of the locking rods is moved, so that the space for the displacement of the locking rods is used up and another extendable furniture part thus can not be pulled out at the same time. In this way works also from the EP 1 500 763 A2 Outgoing pull-out device. The locking bars are here operated by the spring-loaded tilting slide, of which the pull-out furniture parts are retracted in the last section of the Einfahrweges. The movement of the tilt slide is again damped by dampers, which are formed by piston-cylinder units.

Ausziehsperrvorrichtungen with locking rods are known in various other embodiments. For example, the DE 29 620 152 U1 . EP 1 336 709 A1 and WO 2008/107499 A1 show an actuation of the locking rods by actuating parts, which are pivoted about an axis perpendicular to the locking rods when pulling out the respective extendable furniture part. For example, from the GB 2 376 043 A shows a Ausziehsperrvorrichtung, in which the actuating parts are pivoted about axes which are parallel to the longitudinal extent of the locking rods and having cooperating with the locking rods cams.

Other trained in the form of piston-cylinder units damper for damping the retraction of movably mounted furniture parts go for example from the DE 20 2005 020 820 U1 and DE 10 213 726 A1 out. Known are further rotational damper, in which a highly viscous damping medium is arranged in a gap between a fixed damper part and a rotatably mounted damper part. The braking force is caused by this sheared damping medium. Damper of this kind, for example, go from the DE 10 210 917 C1 . US 5,277,282 A . JP 59-222631 A and US 5,143,432 A out.

Furthermore, purely mechanically acting friction damper are known. So go for example from the DE 19 938 626 A1 . DE 201 16 197 U1 and JP 01-266331 A Umschlingungsteile out, which surround an internal friction and form with this a friction pairing. Friction dampers have the disadvantage that the braking force exerted by them is basically independent of speed.

From the DE 10 313 659 B3 . DE 10 214 596 A1 . DE 19 717 937 A1 . AT 503 877 B1 and EP 1 260 159 A2 go piston-cylinder units in which a between the two sides of the piston forming air pressure difference acts on an elastically deformable piston part, so that the applied friction force depends on the air pressure difference and thus on the speed of the component to be damped. A vehicle shock absorber, in which a flexibly formed loop part, which bears rubbing against an inner friction part formed by a friction drum, emerges from the DE 601 293 C out. By coupling one end of the belt part with a hydraulically acting damper, the frictional force acting between the belt part and the friction drum can be influenced.

An intake mechanism with a kinked formed, rotatably mounted about a stationary horizontal pivot axis Einziehteil goes out of the EP 1 384 420 B1 out. The Einziehteil is acted upon by a pull-in spring, which is integrated in a damper forming a piston-cylinder unit. At the back of the pull-out furniture part, for example, a high cabinet drawer, a cooperating with the retraction part driver is arranged. When pivoting the retractable part from a basic position to a waiting position, a dead center of the intake spring is run over.

From the GB 1,117,071 shows a locking device, in which a spring-loaded catch part, which is mounted pivotably about an axis, is pivoted by a catch attached to the extendable furniture part between a basic position and the waiting position. The spring is moved over a dead center.

The DE 10 2009 012 922 A1 shows a collection mechanism with a rotatably mounted about an axis, spring-loaded pull-in part, which has a toothing, via which a rotary damper is driven.

The WO 2009/059338 A1 shows arranged behind the drawers furniture drives through which a respective drawer is ejected. The furniture drives are attached to a common mounting rail via a detachable connection, in particular latched. The mounting rail is adjustable in position relative to the drawers. By attaching to the mounting rail, the distance between the furniture drives can be adjusted to the backs of the drawers in a simple manner by adjusting the mounting rail. The furniture drives can be attached to any position of the vertical extent of the mounting rail on this.

From the EP 09 35 076 A1 shows a fastening device for fastening a plurality of furniture fittings, which comprises an anchoring rail and a locking rail. The fittings to be attached are inserted by means of fastening pins in respective holes of the anchoring rail and further secured by a vertical displacement of the anchoring rail by means of an eccentric. The fittings to be installed are, for example, base plates of hinges, shelf supports and mounting rails for drawer slides.

From the US Pat. No. 7,815,267 B1 A pull-out system for pull-out furniture parts emerges whose pull-in units are integrated in the guide rails. The guide rails are attached by screws to a bar.

A device of the type mentioned is from the DE 20 2009 002 035 U1 out. In one of the training mentioned in this document Einzieheinheiten are fixedly mounted on the vertical guide a locking bar.

The US 5,303,994 A describes a pull-out device that can be attached by means of snap elements as a unit to a body at different positions.

The WO 2006/017865 A1 describes a tool-free attachment of one or more components, preferably ejection devices for ejecting a movable furniture part, by means of snap connections.

The object of the invention is to provide an easy-to-install retraction system of the type mentioned. According to the invention, this is achieved by a pull-in system having the features of claim 1.

In a pull-in system according to the invention, at least one pull-in unit is provided for each of the pull-out furniture parts, each of which has a pull-in part acted upon by a pull-in spring and a bearing unit that supports it in an adjustable manner between a basic position and a waiting position. The Einziehteil acts in each case with a driver, which moves when pulling and pushing the pull-out furniture part with the pull-out furniture part, preferably arranged on this (an arrangement of a part of the pull-out for the pull-out furniture part would also be conceivable and possible). Furthermore, at least one mounting rail is present, which is to be attached to the furniture body. The mounting rail has a plurality of mounting locations, on each of which one of the bearing units can be fastened. For this purpose, a respective mounting place has at least one mounting element for fastening a respective bearing unit.

Preferably, only one retractable unit is provided for each of the extendable furniture parts, and the retractable units of all retractable furniture parts are mounted on the same mounting rail, i. there is only a single mounting rail provided.

When mounting the Einziehsystems thus directly on the furniture body only the at least one mounting rail must be attached. The Einzieheinheiten are then attached with their storage units at mounting locations of at least one mounting rail. The attachment of a respective storage unit on relevant assembly space of the mounting rail via a snap connection.

Preferably, all assembly sites are the same, i. have the same mounting elements for mounting a bearing unit, and the bearing units all have the same connection elements for connection to the mounting elements of the respective mounting place. In particular, all Einzieheinheiten may be identical.

Advantageously, based on the longitudinal extent of the mounting rail middle points of successive mounting positions for each successive mounting positions each have the same distances. It can then be mounted Einzieheinheiten according to the pitch formed by this distance. The dimensions of the extendable furniture parts in the direction of the longitudinal extension of the mounting rail can then be a multiple n of this grid dimension a, where n = 1, 2, 3 ... etc.

The mounting rail preferably has first and second mounting legs which are perpendicular to each other, wherein at least one mounting element is suitably formed for each of the mounting locations on each of the mounting legs. An advantageous embodiment provides that the mounting rail further comprises a support leg, which lies in a plane perpendicular to the first mounting leg and parallel to the second mounting leg level and includes a gap with the first mounting leg, in which in the assembled state of a respective Einzieheinheit a part of the Einzieheinheit is arranged.

The attachment of the storage unit of a respective Einzieheinheit the respective mounting position of the mounting rail according to the invention is such that the bearing unit is first inserted into an insertion direction which is perpendicular to the longitudinal extent of the mounting rail in an intermediate position, wherein the insertion into the intermediate position by the intervention at least a bearing element of the bearing unit is guided in a mounting element of the assembly station, and that in the sequence the bearing unit is displaced in the longitudinal direction of the mounting rail until the mounting position is reached, in which at least one snap element, which can be arranged on the bearing unit or on the mounting rail, snapped into the other of these two parts. The at least one snap element is advantageously arranged on the bearing unit.

In an advantageous embodiment of the invention, the Einziehteile of the bearing units are pivotally mounted about stationary pivot axes, so that they are pivotable about their stationary pivot axis between the basic position and the waiting position. The pull-in parts are thus designed in the form of pivotable levers, in particular one-armed levers, on each of which both the pull-in spring and - during the interaction - the driver attacks. Preferably, the stationary pivot axes lie on a common, parallel to the longitudinal direction of the mounting rail straight lines. When pivoting the respective Einziehteils from its basic position to its waiting position, a dead center of the recoil spring is advantageously overcome, which in this case is more taut in the waiting position than in the basic position of the Einziehteils.

In an advantageous embodiment of the invention, the Einziehsystem for each of the Einzieheinheiten comprises a damping device for damping the insertion of the respective associated extendable furniture part, wherein the pivoting of the respective Einziehteils is damped from the waiting position to the normal position by this damping device. In a particularly preferred embodiment, this damping device comprises at least one rotary damper or is formed by such, wherein the rotary damper has at least one part driven by the Einziehteil in the pivoting of the Einziehteils of its waiting position in its basic position, which is used to exert a braking force during pivoting of the Einziehteils is rotated from the waiting position in its basic position relative to a detained part about the stationary pivot axis of the Einziehteils. It can thereby be achieved an advantageous, compact design.

An inventive pull-in system may, if desired, also be equipped with a pull-out locking device, by means of which only one of a plurality of pull-out furniture parts coupled to one another by the pull-out blocking device can be pulled out at the same time. For this purpose, locking rods of Ausziehsperrvorrichtung are mounted displaceably in the direction of the longitudinal extent of the mounting rail displaceable, wherein at least one of the locking rods of Ausziehsperrvorrichtung is displaced in an adjustment of one of the Einziehteile from its normal position to its waiting position in the axial direction of the storage units. In this case, a space available for the displacement of the locking bars free space is used up, so that a further displacement of the locking bars and thus a withdrawal of another extendable furniture part is blocked. From Einziehteil is operated for axial displacement of at least one of the locking rods in the adjustment of the basic position in the waiting position cooperating with the at least one locking rod operating part. In this case, in one possible embodiment, the actuating part can be rotated about an axis of rotation lying parallel to the longitudinal extension of the mounting rail and interact with the at least one locking bar on the front side via at least one cam or at least one inclined or helical surface. A rotation of the operating part about a right angle to the longitudinal extension of the mounting rail standing axis of rotation is possible in another embodiment.

Conveniently, a respective bearing unit has a cavity which passes completely through this and which extends in the direction of the longitudinal extent of the mounting rail and which receives a portion of at least one of the locking rods of the pull-out locking device. In this case, it is preferably provided in the case of formation of the respective Einzieheinheit with a damping device, which is formed by at least one rotary damper, that the driven and the detained part of this at least one rotary damper extend around said cavity.

A pull-in system according to the invention can advantageously be designed to be suitable for heavy-duty pull-outs. For heavy-duty pull-out furniture parts are provided, of which one, several or all are loaded with more than 150kg.

An embodiment of a Einziehsystems invention is shown in the Fig. 1 to 20 shown. The Einziehsystem serves here for the formation of Selbsteinzügen for trained in the form of drawers extendable furniture parts 1, which are arranged one above the other. An inventive Einziehsystem can also be designed to form Selbsteinzügen for other types of extendable furniture parts, eg for juxtaposed cabinet drawer.

The pull-out furniture parts 1 are over in Fig. 1 Pull-out guides, not shown, can each be pulled out of the furniture carcass 30 in an extraction direction 44 and pushed into the furniture carcass 30 counter to the pull-out direction 44. At the back (based on the pull-out 44) of a respective extendable furniture part 1 a driver 2 is attached to this.

The Einziehsystem has for each of the extendable furniture parts 1 a Einzieheinheit 7, comprising a bearing unit 8 and a cooperating with the respective driver 2 Einziehteil 5, which is movably supported by the storage unit 8, so that the Einziehteil 5 adjustable between a basic position and a waiting position is. The storage units 8 are rigidly connected by means of a mounting rail 29 with the furniture body 30, as will be explained in detail below.

In the exemplary embodiment, a respective driver 2 slide tracks 3, which can be formed as shown by wells or through openings. A respective retraction part 5 has projections 4, which are formed here by rollers and which cooperate with the slide tracks 3. Also designed in other form driving connections, for example, a substantially V-shaped recess into which a projection enters to adjust the Einziehteil 5 from the driver 2 between the basic position and the waiting position and back, are possible. Different types of possible driving connections are known, for example, from conventional pull-out furniture parts with pull-in mechanisms ago.

In the exemplary embodiment, the pull-in parts 5 are pivotably mounted by the bearing units 8 about swivel axles 6 stationary relative to the furniture carcass 30. The pivot axes 6 lie on a common straight line (they therefore coincide) and parallel to the longitudinal extent of the mounting rail 29 (= parallel to the longitudinal axis of the mounting rail 29).

On the one hand on the draw-in part 5 and on the other hand on the bearing unit 8, a draw-in spring 27 engages the respective draw-in unit 7.

For example, latching arms 43 can be arranged on the bearing unit 8 (for example on the bearing part 28 of the bearing unit 8) between which the inner (= closer to the pivot axis 6) end of the pull-in spring 27 can be snapped onto the bearing unit 8.

In the retracted state of the pull-out furniture part, the pull-in part 5 assumes its basic position (cf., for example, the uppermost and the two lowest pull-out furniture parts in FIG Fig. 1 as well as the Fig. 2 and 9 ). When pulling out the pull-out furniture part 1, the pull-in part 5 is pivoted about the pivot axis 6 until it assumes its waiting position (cf., for example, the second-highest drawer in FIG Fig. 1 as well as the Fig. 5, 6 . 7 and 10 ). In this position of the Einziehteils 5, the driver 2 couples from the Einziehteil 5. The pull-out furniture part 1 can be further extended in the sequence until it reaches its fully extended position. When inserting the pull-out furniture part 1 in the direction opposite to the withdrawal direction 44 of the driver 2 runs to the in his waiting position located pull-5. It then follows a mutual coupling of these two parts and a turning back of the Einziehteils 5 in the opposite direction of rotation 26 about the pivot axis 6 until the Einziehteil 5 again assumes the basic position and the pull-out furniture part 1 is completely inserted.

When pivoting the Einziehteils 5 starting from its basic position in the direction of its waiting position, the pull-in spring 27 is first stretched, see. FIGS. 9 and 8 , Shortly before reaching the waiting position, a dead center of the intake spring 27 is crossed (this is the in Fig. 8 shown position), as a result, the pull-in spring 27 until reaching the in Fig. 7 again slightly relaxed (preferably by less than one fifth of the previous compression stroke).

If, when inserting the extendable furniture part of the driver 2 starts at the Einziehteil 5, the driver 2 pivots the Einziehteil 5 via its dead center. In the position of the Einziehteils 5, in which the dead center of the pull-in spring 27 is present, the projections 4 have already run so far into the slide tracks 3, that in a further, caused by the pull-in spring 27 pivoting the Einziehteils 5 about the pivot axis 6, the pull-in fifth positively connected to the driver 2 and the extendable furniture part 1 is retracted by the Einziehteil 5 by the force of the spring 27, until the in Fig. 9 shown basic position of the Einziehteils 5 is reached.

If the pull-in spring 27 can be connected at different distances from the pivot axis 6 to the bearing unit 8, for example by a plurality of latching arms 43 are provided, the strength of the pull-in force can be changed by different biases of the pull-in spring 27. Also connection possibilities at different points of the Einzieharms 5 may be provided or a continuous change of the distance from the pivot axis 6, e.g. by an eccentric element, can be provided.

When pivoting the Einziehteils 5 from the basic position to the waiting position further pivoting of the Einziehteils 5 is blocked in this direction by a between the Einziehteil 5 and a housing-fixed part, such as the rail 29, stop formed. In the reverse pivoting of the Einziehteils a corresponding stop between the Einziehteil 5 and a housing-fixed part, such as the rail 29, be present, which blocks the further pivoting in this direction in the basic position of the Einziehteils. On the other hand, the further pivoting of the Einziehteils 5 could also be limited by the limitation of the further displacement of the extendable furniture part 1 on reaching its fully inserted position.

The rotation of the Einziehteils 5 about the pivot axis 6 of the waiting position in its normal position, ie in the direction of rotation 26, is damped by a damping device described below, wherein the damping device is integrated into a respective Einzieheinheit 7, which thus both the collection function and the Provides damping function. When starting the pull-out furniture part to the waiting in his waiting position pull-in part 5, in the pull-out direction 44 opposite direction, a braking force is thus exerted on the pull-out furniture part 1. After the pivoting of the draw-in part 5 over the dead center of the pull-in spring 27, the pull-in of the pull-out furniture part 1 takes place against the braking force exerted by the damping device.

A respective bearing unit 8 is formed in the embodiment of a first bearing part 10 and a second bearing part 28, which is placed on the first bearing part 10. The pull-in part 5 has openings which surround outer (= away from the pivot axis 6) surfaces of the first bearing part 10, of which the pull-in part 5 is rotatably mounted about the pivot axis 6.

For mounting the bearing units 8 on the mounting rail 29 has this in the direction of its longitudinal extent directly or at a distance successive mounting locations 61, each having at least one mounting member for mounting the bearing unit 8 on the mounting rail 29. The mounting rail 29 is attached to the furniture body 30, for example, by means of screws, the holes 60 in the mounting rail enforce, see. Fig. 1 and 11 (the screws are in Fig. 1 omitted).

The connection of a respective storage unit 8 with the mounting rail 29 at one of the mounting locations 61 of the mounting rail 29 is effected by a snap connection. So there is at least one resilient snap element on one of the two parts to be joined, which snaps into the other of the two parts to be joined in the preparation of the connection, wherein a positive connection between the two connected parts is produced. Preferably, the snap connection is releasable again by the at least one snap element is elastically deflected, whereby the positive engagement is canceled. Preferably, the at least one snap element is arranged on the bearing unit snaps into at least one of the mounting elements of the respective mounting place 61 of the mounting rail 29 a.

The mounting rail 29 has mutually perpendicular first and second mounting legs 29a, 29b. The first mounting leg 29a is connected in the embodiment via an angled portion with the second mounting leg 29b. Furthermore, the mounting rail 29 has a support leg 29c lying parallel to the second mounting leg 29b. In the exemplary embodiment, the first mounting leg 29a is connected via an angled portion with the support leg 29c. The mounting rail thus has a (relative to the cross section) U-shaped training, optionally with different length U-legs. Between the second mounting leg 29b and the support leg 29c is a gap. In the mounted state of the storage unit 8, this is at least partially in this space.

In the embodiment shown, the snap connection between the respective bearing unit 8 and the mounting rail 29 comprises first and second snap elements 62, 63 of the bearing unit 8, which are formed by resiliently deflectable arms. When inserting the storage unit 8 in the respective mounting place 61, these snap elements 62, 63 snap into openings in the mounting rail 29, which form mounting elements 64, 65 of the respective mounting place 61. The mounting member 64 is here in the first Mounting leg 29a formed and the mounting member 65 is formed in the second mounting leg 29b.

In order to connect a respective bearing unit 8 to the mounting rail 29, the bearing unit 8 is first inserted into a direction perpendicular to the longitudinal extent of the mounting rail 29 insertion direction 66 in the respective assembly space 61 (see. Fig. 13a ), until an intermediate position (cf. Fig. 13b ) is achieved. When inserting the bearing unit 8 until reaching the intermediate position, pins of the bearing unit 8, which form connecting elements 67, 68, 69 of the bearing unit 8, are introduced into mounting elements 70, 71, 72, which are formed by recesses which run parallel to the longitudinal extent of the mounting rail 29 and at right angles to the insertion direction 66 extending free edge 73 of the second mounting leg 29b of the mounting rail 29 go out. Furthermore, hook-shaped connecting elements 74, 75, 76 are inserted through openings in the first mounting leg 29a. The opening, which also forms the mounting element 64 for snapping the snap element 62, in the exemplary embodiment has an extension which serves to insert the hook-shaped connecting elements 74, 75. The opening for insertion of the hook-shaped connecting element 76 forms a mounting member 77 of the respective mounting place 61st

After reaching the intermediate position, the bearing unit is moved in the direction of the longitudinal extent of the mounting rail 29 until the mounting position is reached, in which the snap elements 62, 63 snap into the mounting elements formed by the openings 64, 65. When the bearing unit 8 is moved from the intermediate position into the mounting position, the hook-shaped connecting elements 74, 75, 76 also engage over the edges of the openings forming the mounting elements 64, 77. Characterized a positive connection is formed against pulling in a direction opposite to the insertion direction 66. Furthermore, in the displacement from the mounting position into the intermediate position, the peg-shaped connecting elements 67, 68, 69 are arranged behind steps (relative to the insertion direction 66). the mounting elements 70, 71, 72 pushed. This also forms a positive connection against pulling against the insertion direction 66. The snap elements 62, 63, however, form a positive connection against displacement of the bearing unit 8 in the longitudinal direction of the mounting rail 29 from the mounting position to the intermediate position. The further displacement in the longitudinal direction of the mounting rail 29 in the direction in which the bearing unit 8 has been displaced in the displacement from the intermediate position to the mounting position is achieved by one, several or all of the connecting elements 67, 68, 69, 74, 75 , 76, abut at the edges of the receiving recesses or openings.

Stops 78, 79, 80 of the bearing unit 8 abut on the edge 73 of the second mounting leg 29b and on the first mounting leg 29a.

A displacement of the bearing unit 8 in the direction perpendicular to the insertion direction 66 and at right angles to the direction of the longitudinal extension of the mounting rail 29 is blocked by abutment of the bearing unit on the second mounting leg 29b and the support leg 29c.

Thus, the mounted on the mounting rail 29 bearing unit 8 is positively connected in all directions with the mounting rail 29 and secured against rotation.

With reference to the longitudinal direction of the mounting rail 29 centrally located points of the assembly stations 61 have with respect to the longitudinal direction of the mounting rail 29 equal distances a from each other. This distance a forms a grid. The centers of the pull-out furniture parts 1 lying centrally with respect to the longitudinal direction of the mounting rail 29 may have the distance a or a multiple thereof (2a, 3a, etc.). According to the expansions of the respectively deployable furniture parts 1 used in the longitudinal direction of the mounting rail 29, the bearing units 8 are mounted on the respectively corresponding mounting locations 61.

In the exemplary embodiment, the snap elements 62, 63 and the connecting elements 67, 68, 74, 75 are arranged on the second bearing part 28 and the connecting elements 69, 76 on the first bearing part 10.

The connections between the bearing units 8 and the mounting rail 29 may be formed differently in detail.

In the exemplary embodiment shown, the damping device comprises a first, mechanically acting brake device with two parts rotated relative to one another about the pivot axis 6 (= first rotational damper) and a second braking device coupled thereto, the braking force of which is rotated in a gap between two parts rotated relative to each other about the pivot axis 6 arranged viscous damping medium is caused (= second rotary damper). Due to the coupling of the brake devices, a mutual contact pressure of friction surfaces of the first brake device takes place as a function of the braking force exerted by the second brake device. It is achieved by an overall speed-dependent damping effect, wherein the braking force of the damping device increases with increasing speed.

The Einziehteil 5 is connected to a preformed, but flexible by its elasticity Umschlingungsteil 31, so that the Umschlingungsteil 31 is also rotated upon rotation of the Einziehteils 5 about the pivot axis 6 in the direction of the arrow 26 about the pivot axis 6. The looping part 31 is formed in the embodiment of a band and extends around a major part of the circumference of the first bearing part 10 of the bearing unit 8 around this. The inner (= the axis 6 facing) surface of the Umschlingungsteils 31 forms a driven friction surface 14, which cooperates to generate a braking force with the outer (= away from the axis 6) surface of the first bearing part 10 which forms a fixed friction surface 15 (in Embodiment, this is the lower portion of the wall 40). The driven friction surface 14 and the retained friction surface 15 form the friction pair of first, mechanically acting braking device, which comprises the loop part 31 and the first bearing part 10.

The connection of the Einziehteils 5 with the Umschlingungsteil 31 via an overload spring 32, which is integrally formed in the embodiment shown with the Umschlingungsteil 31 and a spring having a elastic, arcuate or loop-shaped portion of both the Umschlingungsteil 31 and the overload spring 32nd forming band is formed. In other embodiments, an overload spring may be formed in other ways or omitted.

The transition between the wrap-around part 31 and the overload spring 32 can be regarded as the front connection point 33 of the wrap-around part 31, at which the movement of the pull-out furniture part 1 to be damped is introduced into the wrap-around part 31.

At a rear connection point 34, the wrap-around part 31 is connected to the damper sleeve 18. Here, in the illustrated embodiment, an axial projection 35 of the wrap member 31 is inserted into a recess 36 of the damper sleeve 18, see. Fig. 4 , Other training of driving connection are possible.

Between the front connection point 33 and the rear connection point 34, the wrap-around part 31 extends over more than 90 °, preferably over more than 180 °, more preferably over more than 250 ° with respect to the pivot axis 6 about the first bearing part 10 (in the direction of rotation 26 opposite direction of rotation). In the embodiment shown, this extension is less than 360 °. An extension of more than 360 ° is possible, that is, the wrapping part then has more than one complete turn, wherein it runs helically around the first bearing part 10.

The rear connection point 34 of the wrap-around part 31 is connected to the pull-in part 5 via an open-holding spring 25. This hold-open spring 25 is formed integrally with the wrap-around part 31 in this exemplary embodiment and is formed by an arc-shaped or loop-shaped section of the strap, which also forms the wrap-around part 31 and optionally the overload spring 32. The hold-open spring 25 could also be formed by a separate part or omitted.

The overload spring 32 is substantially harder, preferably more than 10 times harder than the hold-open spring 25th

The damper sleeve 18 has in this embodiment, a wall 37 which engages in a slot between an inner and an outer wall 39, 40 of the first bearing part 10. Furthermore, the damper sleeve 18 has a wall 38 which engages over an upper portion of the outer wall 40 of the first bearing part 10. The inner and outer surfaces of the wall 37 of the damper sleeve 18 and the inner surface of the wall 38 of the damper sleeve 18 form driven damper surfaces 21. The outer surface of the wall 39 of the first bearing member 10, the inner surface of the wall 40 of the first bearing member 10 and the upper portion of the outer surface the wall 40 of the first bearing part 10 form retained damper surfaces (the lower portion of the wall 40 forms the retained friction surface 15). Between the driven damper surfaces 21 and the retained damper surfaces 22 is in each case an annular gap, in which a viscous damping medium 23 is arranged. Sealing rings 41, 42 define the gap between the outer surface of the wall 39 and the inner surface of the wall 37 at the upper end and the gap between the upper portion of the outer surface of the wall 40 and the inner surface of the wall 38 at its lower end, so that a sealed space is trained. As a damping medium, therefore, a flowable oil can be used. The use of a non-flowable fat is also possible.

The second brake device thus comprises the damper sleeve 18, the first bearing part 10 and the damping medium 23.

By the rotation of the Einziehteils 5 about the pivot axis 6, the wrap member 31 is rotated about the pivot axis 6, whereby this is rotated by the connection of the Umschlingungsteils 31 with the damper sleeve 18 about the pivot axis 6. Depending on the speed of rotation of the damper sleeve 18 about the pivot axis 6, the second braking device exerts a more or less large braking force, whereby between the front joint 33 and the rear joint 34 of the wrap 31 acts a more or less large tensile force. Depending on the size of this tensile force is a more or less strong contact pressure of the driven friction surface 14 to the fixed friction surface 15th

In the resting state of the device, the wrap-around part 31 advantageously at least in sections at a distance from the fixed friction surface 15. Preferably, the wrapping part 31 has at least substantially the entire course of its friction surface 14 due to its preforming in the resting state, i. at least over 90% of its extent in the circumferential direction, a distance from the friction surface 15 of the first bearing part 10.

By the hold-open spring 25, which acts on the rear connection point 33 of the Umschlingungsteils 31 opposite the front connection point 33 of the Umschlingungsteils 31 and against the Einziehteil 5 in the direction of rotation 26, the friction surface 14 of the Umschlingungsteils 31 is then up to a limit of the speed of the pull-out furniture part 1 or a limit value of the rotational speed of the Einziehteils 5 spaced from the friction surface 15 of the first bearing member 10 (at least largely) and the first brake device is substantially ineffective (ie, their braking effect is anyway smaller than the braking effect of the second brake device). Only when exceeding this limit, the first braking device is effective.

At a high speed with which the pull-out furniture part 1 impinges on the Einziehteil 5, it would come without the overload spring 32 to a suddenly occurring high braking force of the device, which undesirable high loads and an undesirably strong braking of the pull-out furniture part 1 would be the result. By the overload spring 32, the peak of the braking force is cushioned by the Einziehteil 5 can rotate relative to the wrap member 31 under deformation of the overload spring 32.

Since the speed of retraction against the braking force exerted by the braking device, possibly after damping the first faster speed of the pull-out furniture part 1 when starting against the Einziehteil is relatively low from the pull-in spring 27 substantially only the relatively low braking force of the second brake device must be overcome , The force of the pull-in spring 27 can thus be designed relatively low, which facilitates the extraction of the pull-out furniture part 1.

When turning back the Einziehteils 5 in the direction of rotation 26 opposite direction of rotation of the Einziehteil 5 via the hold-open spring 25, the damper sleeve 18 is rotated so that the force to be overcome in this case is exercised. This force is comparatively low, since the first brake device is not effective in this direction of rotation. If the application of such a force is not desired, however, a freewheel, which is closed in the direction of rotation 26, can be provided between a part connected to the wrap-around part 31, optionally via the hold-open spring 25 and / or the overload spring 32, and the pull-in part 5 opens in the opposite direction of rotation. Such freewheel are known, also in connection with dampers.

In a modified embodiment in relation to the illustrated embodiment, the pull-in part 5 could also be pivotably mounted on the damper sleeve 18 and indeed about a pivot axis 6 parallel to the axis of rotation. The connection of the wrap-around part 31 or the overload spring 32 connected to the wrap-around part 31 could then be radially outside of the pull-in part 5 Rotary axis done. By a return spring, the retraction part 5 could be acted upon in an initial position with respect to its axis of rotation relative to the damper sleeve 18. When damping the movement of the pull-out furniture part 1, when the pull-in part 5 is more or less pivoted against the force of the spring acting on it about the axis of rotation, since the rotation of the axis of rotation about the pivot axis 6 is braked by the braking force of the second brake device, the loop part 31 more or less tightened and pressed against the retained friction surface 15. The draw-in spring 27 would in turn be arranged between the draw-in part 5 and a body-fixed part, for example the housing part 28.

The friction pairing or at least one of the friction pairings of the first brake device expediently has a sliding friction coefficient of at least 0.2, preferably at least 0.3.

The viscosity of the viscous damping medium of the second braking device is advantageously more than 20,000 Pa s, preferably more than 50,000 Pa s, with values in the range of 100,000 to 1,000,000 Pa s are particularly preferred.

The gap width of the gap or at least one of the gaps, preferably all the gaps, in which or in which the damping medium is arranged, is advantageously in the range of 0.1 mm to 0.5 mm, i. the damping medium has such a layer thickness.

The wrap-around part 31 can also be formed by a wire, in particular a spring wire, or a cord instead of a band. The wrap angle of the wire or cord is favorably between 90 ° and 530 °, preferably between 180 ° and 500 °, with a wrap angle between 250 ° and 330 ° is particularly preferred.

In the illustrated embodiment, a pull-out locking device is further integrated into a pull-in system according to the invention.

Ausziehsperrvorrichtungen serve that of several on the Ausziehsperrvorrichtung coupled extendable furniture parts only one is simultaneously extendable. Only after the insertion of this pull-out furniture part another can be pulled out. Further, if desired, a central locking can be provided via such a pull-out locking device.

In the embodiment of the Ausziehsperrvorrichtung shown in the embodiment extend between actuators, which are assigned to the individual extendable furniture parts, locking bars, which have only a limited space (= a limited game) for their displacement. If one of the pull-out furniture parts pulled out, so are the two (if it is a middle extendable furniture part, the operating part on both sides locking bars are arranged) with the actuating part cooperating locking rods moved apart from the operating part. As a result, the existing space is used up, so that a movement apart of cooperating with another of the operating parts locking rods is no longer possible and thus no more extendable furniture part can be pulled out more. The operating part of an end-side extendable furniture part can also interact only with a locking bar, which shifts it when pulling out this extendable furniture part. The basic design of Ausziehsperrvorrichtung corresponds to the extent of the prior art, for example, according to the aforementioned writings to Ausziehsperrvorrichtungen.

The Ausziehsperrvorrichtung comprises the locking rods 48, 49 which are actuated by operating parts 47 of the Einzieheinheiten 7.

The locking rods 48 each extend between the adjacent pull-out furniture parts 1 associated Einzieheinheiten 7. Between one of the end-side extendable furniture parts 1, in the illustrated embodiment, the uppermost extendable furniture part 1, associated Einzieheinheit 7 and a Stop 59 (see. FIGS. 14 and 15 ), which is arranged stationarily to the furniture body 30, for example, is arranged on the mounting rail 29, an additional locking bar 49 extends. The locking bar 49 extends from the Einzieheinheit 7 in a direction away from the other Einzieheinheiten 7 direction.

In the fully retracted position of all extendable furniture parts 1 is a distance a between the stop 59 facing the end of the locking rod 49 and the stopper 59 before (see. Fig. 14 ).

The longitudinal axes of all locking rods 48, 49 are parallel to each other and on a common straight line which is parallel to the longitudinal extent of the mounting rail 29.

Apart from the operating part 47, which is provided for displacing the farthest from the stop 59 located locking bar 48, the actuating members 47 are each between two of the locking rods (one between the locking rods 48, 49, the other between two locking rods 48) and are together with these locking rods 48, 49 arranged displaceably. The pull-out of one of the pull-out furniture parts 1 from the Einziehteil 5, which is pivoted when pulling out this extendable furniture part 1, displaced actuating member 47 shifts all seen from him closer to the stop 59 lying locking rods 48, 49 together with the intermediate operating parts 47 together.

In the embodiment, a respective actuating member 47 is formed in the form of a cam and rotatably connected to the Einziehteil 5 of the respective Einzieheinheit 7. In this case, the actuating part 47 can be displaced by a limited distance relative to the retraction part 5 in the direction of the pivot axis 6, while still remaining in rotationally fixed connection with the retraction part 5. For example, for this purpose, the Einziehteil 5 as shown in the direction of the pivot axis 6 extending claws 52 which engage in recesses 53 of the actuating member 47. At the lower ends of rod parts 48a the locking rods 48 each have a rotatably held cam follower part 50. At the upper ends of the rod parts 48a, the locking rods 48 each have a rotationally fixed cam follower part 51. The cam follower part 50 is held against rotation by support on the mounting rail 29, but in the longitudinal direction of the mounting rail 29 relative to this slidably. The cam follower part 51 is rotatably held by support on the first bearing part 10 (via axial webs which engage in axial recesses), but in the longitudinal direction of the mounting rail 29 relative to the first bearing part 10 slidably. At the Einzieheinheit 7 facing the end of the rod portion 49a of the locking rod 49, a cam follower part 50 is arranged, which is rotatably held in an analogous manner by support on the mounting rail 29.

If one of the pull-out furniture parts 1 pulled out, so is the pivoting of the Einziehteils 5 of the associated Einzieheinheit 7 of its basic position in its waiting position, the actuating member 47 of this Einzieheinheit 7 adjusted from a first to a second position, whereby the cooperating with this operating part 47 locking bar 48th 49, which extends from this actuating part 47 in the direction of the stop 59, is displaced by the actuating part 47. If it is the operating part 47 cooperating with the locking bar 49, only the locking bar 49 is displaced in the direction of the stop 59 until at least substantially the existing clearance has been used up (the distance a has decreased to less than one fifth of the initial value, see. Fig. 15 ). If another of the pull-out furniture parts 1 pulled out, so are all operating between the actuating member 47 and the stop 59 locking rods 48, 49 and lying between the locking rods 48, 49 actuation parts 47 are moved towards the stop by the operating part 47 of the associated Einzieheinheit.

After removing one of the extendable furniture parts 1 thus a further displacement of the locking rods 48, 49 and the operating parts 47 lying between them is no longer possible. The pull-in parts 5 of the other extendable Furniture parts 1 are thus blocked in their basic positions, so that a displacement of the associated driver 2 is blocked in the withdrawal direction 44.

When retracting the extended pull-out furniture part 1, the associated Einziehteil 5 is adjusted from its waiting position to its normal position and this adjusts the operating member 47 of this Einzieheinheit 7 from the second position back to the first position, whereupon the distance a between the locking bar 49 and the stop 59th is restored.

The actuating member 47, which is assigned to the remote from the stop 59 end of the farthest from the stop 59 located locking bar 48 is also slidably disposed in the illustrated embodiment in the direction of the longitudinal axes of the locking rods 48, 49, so that Einzieheinheit 7 formed the same as the others is. The displaceability of this operating part 47 in the direction of the longitudinal axes of the locking rods 48, 49 can also be omitted.

In the illustrated embodiment, the extendable furniture parts 1 are arranged one above the other and when you take off one of the extendable furniture parts 1, the locking bar 48, 49 extending from belonging to this extendable furniture part 1 operating part 47 upwards, and any overlying locking rods 48, 49 and intermediate Operating parts 47 shifted upward. To assist in the retraction of the parts when retracting the pull-out furniture part 1, a spring could be provided between the stop 59 and the locking bar 49. A displacement of the locking rods 48, 49 and intermediate operating parts 47 down is conceivable and possible, wherein the stop 59 is disposed below the bottom extractable furniture part 1 1 associated Einzieheinheit 7 and the locking rod 49 extends between this Einzieheinheit 7 and the stopper 59. Furthermore, the extendable furniture parts 1 could also be arranged side by side, with the longitudinal axes of the locking rods 48, 49 and the pivot axes 6 would extend horizontally. Basically conceivable and possible are also relative to the horizontal inclined arrangements of the locking rods 48, 49 and the mounting rail 29th

Depending on the dimensions of the extendable furniture parts 1 in the direction of the longitudinal axes of the locking rods 48, 49, locking rods 48, 49 of different lengths can be used (the lengths of the individual locking rods 48 may also differ from each other, as shown in the figures).

In the FIGS. 18 and 19 the positions of a Einzieheinheit 7 are compared when the corresponding pull-out furniture part 1 is retracted, wherein in Fig. 18 also retractable furniture parts are retracted, the Einzieheinheiten are assigned, which are further away from the stop 59, while in Fig. 19 one of these pull-out furniture parts is pulled out. In Fig. 20 the state is shown in the extended position of the associated pull-out furniture part 1.

If desired, a central locking can be realized (not shown in the figures). For this purpose, in the fully retracted position of all extendable furniture parts, a latch member in the space between the locking rod 49 and the stop 59 are retracted, which blocks a displacement of the locking rods 48, 49 and the intermediate operating parts 47 in the direction of the stop 59.

The stationary bearing units 8 have a continuous through, extending in the direction of the pivot axis 6 extending cavity 46. Of these cavities portions of the locking rods 48 are added. It also guides for the axial displacements of the locking rods 48 are formed.

The cam follower part 50 has an axial extension 50a with latching tongues 50b. The cam follower 51 has an axial extension 51a with latching tongues 51b. The cam follower part 51 is insertable into the cavity 46 with the extension 51a, and the cam follower part 50 is connected to the extension 50a through a central opening of the Actuator 47 through inserted into a central opening of the cam follower part 51. By the locking tongues 50b, 51b, the parts are held together for ease of assembly prior to assembly of the device, wherein after installation, the required range of motion is maintained.

The locking rods 48 and / or 49 could consist of several separate rod parts, which can be connected to each other or only adjacent to each other in the direction of the longitudinal axis of the locking rod are guided displaceably. The rod parts can be formed in this case in particular the same length. At different distances between the extendable furniture parts 1 then different numbers of such rod parts could then be used.

The operation of the locking rods 48, 49 could also be done in other ways. Such another possible training is in the Fig. 21 to 24 shown. Here, the actuating part 47 is formed in the form of a cam part which is pivotable about a pivot axis 54 lying at right angles to the pivot axis 6. The actuating member 47 acts in this case with the end of the at least one adjacent locking bar 48, 49 or connected to this locking bar part together to move the locking bar 48, 49 in its pivoting about the pivot axis 54 in the respective direction parallel to the pivot axis 6.

The actuating part 47 has an actuating arm 47a, which projects radially from the pivot axis 54 and is in communication with a sleeve 55 rotatable about the pivot axis 6. Upon rotation of the sleeve 55 about the pivot axis 6, the actuating member 47 is pivoted about the pivot axis 45. Between the sleeve 55 and the actuating arm 47a, a limited displacement in the direction of the pivot axis 6 is possible, for example, by a fork-shaped configuration of the end of the actuating arm 47a, in which a pin 55 mounted on the pin 56 engages.

The sleeve 55 may be connected to the Einziehteil 5 or another part which rotates about the pivot axis 6 when the Einziehteil 5 is rotated about the pivot axis 6, for example, with the damper sleeve 18. Also integrally formed with the Einziehteil 5 or rotated about the pivot axis 6 part, for example, the damper sleeve 18 is possible.

In the figures described above, a bent leaf spring is provided as a pull-in spring. Traction springs designed in another way may also be provided. For example, torsion springs (with a desired number of turns between the two end legs) or coil springs could be used. Also, a curved leaf spring could be provided which has a greater width in a central region than in the end-side attachment regions. The bend could in this case run in a different direction than shown (for example, upwards or downwards).

The damping device could also be designed in a different way than described. Damping devices with only a single braking device, for example, with a viscous damping medium in a gap between a driven and a detained part may be provided when the braking force achieved thereby is sufficient.

Although an attachment of the driver 2 on the backs of the pull-out furniture parts 1 will be advantageous in many applications, other, for example, lateral attachments to the pull-out furniture parts 1 are possible.

A respective driver could also be fixed to a attached to the extendable furniture part 1 body-fixed mounting rail a pull-out for the pull-out furniture part.

Pro extendable furniture parts 1 could also be more than one Einzieheinheit 7 may be provided. The Einzieheinheiten 7 could then at a corresponding Number of mounting rails 29 may be attached (so with two Einzieheinheiten per extendable furniture part two mounting rails could be provided).

In the described embodiment, the pull-in parts for adjustment between the basic position and the waiting position about a parallel to the longitudinal extent of the mounting rail pivot axis 6 are rotatable, as is preferred. Instead, the pivot axis 6 of a respective Einziehteils 5 could also be aligned at right angles to the longitudinal extent of the mounting rail.

Also trained in other ways Einziehteile according to the invention defined in the claims could be provided. So Einzieheinheiten could be provided with movable along tilting guideways Kippschiebern or with linearly displaceable carriage, on each of which a pivotable sliding part is arranged.

The Einziehsystem could also be designed without Ausziehsperrvorrichtung.
