Description

Pull-in system for several pull-out furniture parts

The invention relates to a pull-in system for a plurality of extendable

Furniture parts which are each extendable in a pull-out of a furniture body and in a pull-out direction opposite to the furniture body inserted, comprising for each of the pull-out furniture parts one

Einzieheinheit, each one acted upon by a collection spring Einziehteil which of a pulling out the pull-out furniture part with the

extendable furniture part mitbewegten driver between a basic position, which occupies the Einziehteil in the retracted state of the pull-out furniture part, and a waiting position in which the driver decouples when pulling out the pull-out furniture part of Einziehteil, is adjustable, and adjustable the Einziehteil between the basic position and the waiting position overlaying

Has storage unit.

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 feeder mechanisms) for each of the extendable furniture parts that move automatically upon insertion of the pull-out furniture part of this over a final section of the Einfahrweges and so the fully retracted state of the

make sure that the furniture part can be pulled out. Such Einzieheinheiten are in

different embodiments known. For example, AT 401334 B discloses a retraction mechanism in which a tilting slide displaceable against the force of a spring is present. The tilting slide is arranged tiltable about a tilting axis on a slide which can be moved in a straight line in the pull-out direction of the drawer against the force of the spring. In the case of the draw-in unit known from AT 393948 B, a tilt slide is likewise present, 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 with insert dampers

equipped to dampen the retraction of the extendable furniture part in the last section of the Einfahrweges. Such a damped pull-in device, in which the tilting slide cooperates with a push-in damper, is known, for example, from EP 1 532 892 A1. The spring loaded

Tilting slide cooperates here with a linear damper in the form of a piston-cylinder unit, which acts in particular pneumatically. Also by means of

Rotary dampers damped Selbsteinzüge are known.

From EP 1 500 763 A2 a self-feeder shows that with a

Pull-out device is combined. By pull-out devices, simultaneous withdrawal of two or more pieces of furniture coupled together by the pull-out lock device, e.g. arranged one above the other

Drawers, prevented. The extendable furniture parts are therefore only alternately extendable. Also a central locking becomes over such

Pull-out devices often realized. In a conventional form of locking rods are available, which only a limited space for their

Have shift. For each extendable furniture part an actuating part is provided, which cooperates with at least one of the locking rods. When removing one of the pull-out furniture parts, at least one of

Locking rods moved so that the clearance for the displacement of the

Locking rods is used up and thus another pull-out furniture part can not be pulled out at the same time. In this way, the pull-out locking device which results from EP 1 500 763 A2 also works. The locking rods are actuated here 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 in turn dampened by dampers, which are formed by piston-cylinder units. Ausziehsperrvorrichtungen with locking rods are known in various other embodiments. For example, DE 29 620 152 U1, EP 1 336 709 A1 and WO 2008/107499 A1 show an actuation of the locking rods

Actuating parts which are pivoted about an axis perpendicular to the locking rods when pulling out the respective extendable furniture part.

For example, from GB 2 376 043 A a Ausziehsperrvorrichtung shows in which the operating parts are pivoted about axes which are parallel to

Longitudinal extension of the locking rods lie and with the locking rods

having cooperating cams.

Other designed in the form of piston-cylinder units damper for

Steaming the retraction movement of movably mounted furniture parts can be seen for example from DE 20 2005 020 820 U1 and DE 10 213 726 A1. Known are further rotational damper, in which in a gap between a

fixed damper part and a rotatably mounted damper part

highly viscous damping medium is arranged. The braking force is caused by this sheared damping medium. Dampers of this type can be seen for example from DE 10 210 917 C1, US 5,277,282 A, JP 59-222631 A and US 5,143,432 A.

Furthermore, purely mechanically acting friction damper are known. Thus, for example, DE 19 938 626 A1, DE 201 16 197 U1 and JP 01-266331 A disclose loop parts which surround an inner friction part and form a friction pair with it. Friction dampers have the disadvantage that the braking force exerted by them is basically independent of speed.

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 show piston-cylinder units in which an air pressure difference forming between the two piston sides points to a elastically deformable piston part acts, so that the applied frictional force of the

Air pressure difference and thus the speed of the component to be damped depends. A vehicle shock absorber in which a flexibly formed loop part, which bears rubbing against an inner friction part formed by a friction drum, is disclosed in DE 601 293 C. 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.

A pull-in mechanism with a kinked formed, rotatably mounted about a stationary horizontal pivot axis Einziehteil is apparent from EP 1 384 420 B1. 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 GB 1, 1 17771 a locking device shows, in which a

spring-loaded catch part, which is pivotally mounted about an axis, of a mounted on the extendable furniture part driver between a

Basic position and the waiting position is pivoted. The spring is moved over a dead center.

DE 10 2009 012 922 A1 shows a feed mechanism with a spring-loaded pull-in part, which is rotatably mounted about an axis and has a toothing, by way of which a rotational damper is driven.

WO 2009/059338 A1 shows behind the drawers arranged 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 in position relative to the

Drawers adjustable. By attachment. On the mounting rail, the distance between the furniture drives to the backs of the drawers in a simple manner be adjusted 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 EP 09 35 076 A1, a fastening device for fastening a plurality of furniture fittings emerges, 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 attached are

For example, base plates of hinges, shelf supports and

Guideways for drawer slides.

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

Retraction system with the features of claim 1.

In a Einziehsystem according to the invention is for each of the extendable

Furniture parts provided at least one Einzieheinheit, each one acted upon by a collection spring Einziehteil and this between a

Basic position and a waiting position adjustable storage bearing unit has. The retractable part acts together with a driver, who is in

Pulling and pushing the pull-out furniture part with the pull-out furniture part moved, 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 a single Einzieheinheit is provided for each of the extendable furniture parts and the Einzieheinheiten all extendable furniture parts are mounted on the same mounting rail, ie it 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 with their storage units at assembly stations of at least one

Mounting rail attached. The attachment of a respective storage unit at the respective mounting location 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 assembly site. In particular, all Einzieheinheiten may be identical.

Advantageously, based on the longitudinal extent of the mounting rail middle points of successive mounting positions for all

successive assembly sites each have the same distances. It can then Einzieheinheiten corresponding to the distance formed by this

Grid dimension can be mounted. 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 a Includes clearance with the first mounting leg, in which in the mounted state of a respective Einziehheinheit a part of the Einzieheinheit is arranged. The attachment of the storage unit of a respective Einzieheinheit at the respective mounting location of the mounting rail is advantageously carried out such that the storage unit initially in an insertion direction perpendicular to the

Longitudinal extent of the mounting rail is inserted into an intermediate position, wherein the insertion into the intermediate position by the engagement of at least one connecting element of the bearing unit in a mounting element of the

Assembly space is guided, and that in the sequence the bearing unit is moved in the longitudinal direction of the mounting rail until the mounting position is reached, in the at least one snap element, which on the bearing unit or on the

Mounting rail can be arranged, is snapped into the other of these two parts. The at least one snap element is hereby

advantageously arranged on the storage 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 about their stationary pivot axis between the basic position and the

Waiting position are pivotable. The Einziehteile are thus in the form of

formed pivotable levers, in particular one-armed levers, in each of which both the catch 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 the respective Einziehteils from the waiting position in the

Basic position is damped 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 during the pivoting of the Einziehteils of the waiting position in its basic position, which is used to exert a braking force in the 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 Einziehsystem can, if desired, with a

Ausziehsperrvorrichtung be equipped by which of several of the pull-out locking device coupled together extendable furniture parts only one at a time extendable. These are favorably of the

Bearing units Locking rods of the pull-out device in the direction of

Lengthwise extension of the mounting rail slidably mounted, wherein at least one of the locking rods of the Ausziehsperrvorrichtung is displaced in an adjustment of one of the Einziehteile from its basic position to its waiting position in the axial direction. Here is one for the displacement of the locking bars

used up existing free space, so that a further shift of the

Locking rods and thus a pulling out 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 one possible embodiment, the actuating part may be rotatable about an axis of rotation lying parallel to the longitudinal extension of the mounting rail and may have at least one cam or at least one inclined or

Screw surface cooperate with the front side at least one locking bar. 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 storage unit has a complete this

passing through, extending in the direction of the longitudinal extension of the mounting rail cavity, a portion of at least one of

Receiving locking rods of the pull-out device. This is preferably in the case of training the respective Einzieheinheit with a

Damping device, which is formed by at least one rotary damper, provided that the driven and the detained part of this at least one rotary damper extend around said cavity around.

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 FIGS. 1 to 20. The Einziehsystem serves here to form Selbsteinzügen for trained in the form of drawers extendable furniture parts 1, the

are arranged one above the other. A pull-in system according to the invention can also be designed to form self-feeds for other types of pull-out furniture parts, e.g. for juxtaposed cabinet extensions.

The extendable furniture parts 1 are not shown in Fig. 1

Pull-out guides each extendable in an extraction direction 44 from the furniture body 30 and against the pull-out direction 44 in the furniture body 30th

insertable. 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, a bearing unit 8 and a with the respective driver. 2

includes cooperating pull-in part 5, which is movably supported by the storage unit 8, so that the Einziehteil 5 between a basic position and a

Waiting position is adjustable. The storage units 8 are by means of a

Mounting rail 29 rigidly connected to 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 trained in other form carrier compounds, for example, an im

Essentially V-shaped recess into which a projection enters to the Einziehteil 5 from the driver 2 between the basic position and the

Waiting position and back to adjust 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 Einziehteil 5 and on the other hand on the storage unit 8 engages a

Pull-in spring 27 of the respective Einzieheinheit 7 at.

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 (see, for example, the uppermost and the two lowest extractable furniture parts in Fig. 1 as well as Figs. 2 and 9). When taking off the pull-out

Furniture part 1, the Einziehteil 5 is pivoted about the pivot axis 6 until it assumes its waiting position (see, for example, the second uppermost drawer in Fig. 1 and Figs. 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 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. Fig. 9 and 8. Shortly before reaching the waiting position, a dead center of the pull-in spring 27 is crossed (this is the position shown in Fig. 8), in the sequence is the

Retraction spring 27 is again slightly relaxed (preferably by less than one fifth of the preceding compression stroke) until it reaches the rest position shown in FIG. 7.

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

Pull-in spring 27 is present, the projections 4 are already so far in the slide tracks 3, that in another, caused by the pull-in spring 27

Pivoting the Einziehteils 5 about the pivot axis 6, the retractable part 5 is positively connected to the driver 2 and the extendable furniture part 1 is retracted by the Einziehteil 5 by the force of the pull-in spring 27 until the basic position of the Einziehteils 5 shown in Fig. 9 is reached.

If the pull-in spring 27 can be connected at different distances from the pivot axis 6 with the bearing unit 8, for example by a plurality of latching arms 43 are provided, the strength of the pull-in force can

different bias voltages of the spring 27 can be changed. Also connection options 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 in the

Waiting is a further pivoting of the Einziehteils 5 in this direction by a between the Einziehteil 5 and a housing-fixed part,

for example, the rail 29, blocked stop. 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, the other in the basic position of the Einziehteils

Pivoting blocked in this direction. On the other hand, the other could

Swiveling the Einziehteils 5 also by the limitation of the other

Displacement of the extendable furniture part 1 to be limited upon reaching its fully inserted position.

The rotation of the Einziehteils 5 about the pivot axis 6 of the waiting position in its basic 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

Feed function and the damping function provides. 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 storage unit 8 is in the embodiment of a first

Bearing part 10 and a second bearing part 28 is formed, which is placed on the first bearing part 10. The Einziehteil 5 has openings, the outer (= of the

Pivoting axis 6 away) surfaces of the first bearing part 10 surrounded, of which the Einziehteil 5 is rotatably mounted about the pivot axis 6. For mounting the bearing units 8 on the mounting rail 29, this has in

Direction of their longitudinal extension directly or at a distance successive assembly stations 61, which each have at least one mounting member for fixing the bearing unit 8 to 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 1 1 (the screws are omitted in Fig. 1). 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 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 in

Embodiment over an angled portion with the second

Mounting leg 29b connected. 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 exemplary 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 bearing unit 8 in the respective mounting place 61, these snap elements 62, 63 snap into openings in the mounting rail 29, which mounting elements 64, 65 of the respective

Form assembly station 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.

To connect a respective bearing unit 8 with the mounting rail 29, the bearing unit 8 is first in a perpendicular to the longitudinal extent of

Mounting rail 29 lying insertion 66 is introduced into the respective assembly space 61 (see Fig. 13a), until an intermediate position (see Fig. 13b) is reached. 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. Continue to

hook-shaped connecting elements 74, 75, 76 through openings in the first

Mounting leg 29a introduced. The opening, which also forms the mounting element 64 for snapping the snap element 62, has this in the

Embodiment 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

Assembly site 61.

After reaching the intermediate position, the bearing unit in the direction of

Longitudinal extent of the mounting rail 29 is displaced 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 moving the

Bearing unit 8 from the intermediate position to the mounting position, it is further to the fact that the hook-shaped connecting elements 74, 75, 76 engage over the edges of the mounting elements 64, 77 forming openings. As a result, a positive connection against pulling out in one of the insertion 66th

formed opposite direction. Furthermore, in the displacement from the mounting position to the intermediate position, the peg-shaped

Connecting elements 67, 68, 69 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 hit 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 perpendicular to the direction of the longitudinal extent of the mounting rail 29 is by conditioning the bearing unit on the second mounting leg 29b and on

Supporting leg 29c blocked. 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 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 embodiment shown, the damping device comprises a first, mechanically acting braking device with two against each other around the

Pivot axis 6 twisted parts (= first rotation damper) and coupled to this second brake device, the braking force of a twisted in a gap between two against each other about the pivot axis 6 parts

arranged viscous damping medium is caused (= second

Rotary damper). By the coupling of the braking devices, a mutual contact pressure of friction surfaces of the first braking device takes place in

Dependence on the braking force exerted by the second braking 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 at a

Rotation of the Einziehteils 5 about the pivot axis 6 in the direction of the arrow 26 is also rotated 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 is for generating a braking force with the outer (= away from the axis 6) surface of the first bearing part 10th

cooperates, which forms a detained 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 wrap member 31 via an overload spring 32, which in the embodiment shown in one piece with the

Umschlingungsteil 31 is formed and from a spring elasticity

having formed, arcuate or loop-shaped portion of both the strap member 31 and the overload spring 32 forming band is formed. In other embodiments, an overload spring may be formed in other ways or omitted.

The transition between the loop 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 dampened in

Umschlingungsteil 31 is initiated.

At a rear connection point 34, the loop part 31 with the

Damper sleeve 18 connected. Here, in the illustrated embodiment, an axial projection 35 of the wrap 31 in a recess 36 of

Damper sleeve 18 used, see. Fig. 4. Other embodiments of

Carrier 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

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 31 is over a

Open holding spring 25 connected to the Einziehteil 5. This hold-open spring 25 is formed in this embodiment in one piece with the wrap-around part 31 and is formed by a bow-shaped or loop-shaped section of the band, which also includes the wrap-around part 31 and optionally the

Overload spring 32 is formed. The hold-open spring 25 could also by a

be formed separate part or even 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 21st 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 of the wall 40 of the first bearing member 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 captured 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 is the

Umschlingungsteil 31 is rotated about the pivot axis 6, whereby through the

Connection of the strap 31 with the damper sleeve 18 it is rotated about the pivot axis 6. Depending on the speed of rotation of the

Damper sleeve 18 about the pivot axis 6, the second brake device exerts a more or less large braking force, whereby between the front

Junction 33 and the rear joint 34 of the wrap 31 a more or less large tensile force acts. Depending on the size of this tensile force is a more or less strong contact pressure of the driven friction surface 14 to the friction surface 15 held in the idle state of the device, the wrap member 31 advantageously at least partially spaced from the retained friction surface 15. Preferably, the wrapping 31 has due to its preforming in

Hibernation over at least substantially the entire course of his

Friction surface 14, 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, the rear joint 33 of the

Umschlingungsteils 31 opposite the front joint 33 of the

Umschlingungsteils 31 or compared to the Einziehteil 5 applied in the direction of rotation 26, the friction surface 14 of the Umschlingungsteils 31 is then up to a limit value of the speed of the pull-out furniture part 1 and 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 essentially ineffective (ie their braking effect is in any case less 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 undesirably 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 relative to the

Umschlingungsteil 31 under deformation of the overload spring 32 can rotate.

Since the speed of retraction against the braking force exerted by the braking device, optionally after damping the first faster speed of the pull-out furniture part 1 when starting against the

Pulling-in part, which is relatively low, must be overcome by the pull-in spring 27, essentially only the relatively low braking force of the second brake device. 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 comparison with the illustrated embodiment modified

Embodiment, the Einziehteil 5 could also be mounted pivotably on the damper sleeve 18 and that 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 around the

Swivel axle 6 is braked by the braking force of the second brake device, the strap member 31 is tightened more or less and to the

held friction surface 15 is pressed. The pull-in spring 27 would turn between the Einziehteil 5 and a body-fixed part, such as the

To arrange 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. Of the

Wrap angle of the wire or cord is conveniently 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, on the actuating part on both sides locking bars are arranged) with the operating part cooperating locking rods from

Actuator moved apart. This is the existing free space

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, the of

Operating parts 47 of the Einzieheinheiten 7 are actuated.

The locking bars 48 each extend between the adjacent ones

extendable furniture parts 1 associated Einzieheinheiten 7. Between the 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 stationary to the furniture body 30, for example, arranged on the mounting rail 29, an additional locking bar 49 extends. The locking bar 49 extends from the Einzieheinheit 7 in one of the other Einzieheinheiten 7 direction away.

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 actuating 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

slidably disposed together with these locking rods 48, 49. When pulling out one of the pull-out furniture parts 1 from the Einziehteil 5, the

Taking off this extendable furniture part 1 is pivoted, misaligned

Operating 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 part 47 in the form of a

Cam disc formed 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 51 is by support on the first bearing part 10 (via axial webs, in the axial

Recesses engage) rotatably held, but in the longitudinal direction of the

Mounting rail 29 relative to the first bearing member 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 by the

Swiveling the Einziehteils 5 of the associated Einzieheinheit 7 of the basic position in the waiting position, the actuating member 47 of this Einzieheinheit 7 adjusted from a first to a second position, whereby the with this

Actuating member 47 cooperating locking bar 48, 49 which extends from this actuating part 47 in the direction of the stop 59, is displaced by the actuating member 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 the operating part 47 of the associated Einzieheinheit 7 all between the

Operating member 47 and the stop 59 lying locking rods 48, 49 and the lying between the locking rods 48, 49 operating parts 47 are displaced in the direction of the stop.

After removing one of the extendable furniture parts 1 is thus a further displacement of the locking bars 48, 49 and lying between them

Operating parts 47 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 furthest from the stop 59 located locking bar 48 is also in the illustrated embodiment in the direction of the longitudinal axes of

Locking rods 48, 49 arranged slidably, so that Einzieheinheit 7 is the same as the others formed. 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 the return of the parts when retracting the pull-out furniture part 1, could between the stop 59 and the

Locking rod 49 may be provided a spring. Also a shift of

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 associated Einzieheinheit 7 and the locking bar 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 different length can be used (the lengths of the individual locking rods 48 may also differ from each other, as shown in the figures).

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

extended position of the associated pull-out furniture part 1 shown.

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 can be retracted into the space between the locking rod 49 and the stop 59, which is a

Displacement of the locking rods 48, 49 and the intermediate

Actuators 47 blocked in the direction of the stop 59.

The stationary storage units 8 have an interspersed

continuous, 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 51 a with locking tongues 51 b. The

Cam follower 51 is inserted with the extension 51 a in the cavity 46 and the cam follower part 50 is connected to the extension 50 a through a central opening of the Actuator 47 through inserted into a central opening of the cam follower part 51. By the locking tongues 50 b, 51 b, the parts for

Assembling easier to hold together before assembly of the device, which remain after installation, the required range of motion.

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 a further possible embodiment is shown in FIGS. 21 to 24. Here, the actuating member 47 is in the form of a cam member 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 operating part 47 has an actuating arm 47 a, which is of the

Swivel axis 54 projects radially and is connected to a rotatable about the pivot axis 6 sleeve 55 in conjunction. In the rotation of the sleeve 55 to the

Swivel axis 6, the actuating member 47 is pivoted about the pivot axis 45. Between the sleeve 55 and the actuating arm 47a is a limited

Displacement in the direction of the pivot axis 6 possible, for example, by a fork-shaped configuration of the end of the actuating arm 47 a, in which a mounted on the sleeve 55 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 to the

Swivel axis 6 is rotated, for example, with the damper sleeve 18. Also a one-piece design with the Einziehteil 5 or the 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 in a central region has a greater width than in the end-side

Has connection areas. 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. Also damping devices with only a single

Brake 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 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.
