Each of the locking units (60) has a swivelably mounted catch arm (5) that can be swiveled about a stationary swivel axis (6) lying in parallel to the longitudinal axes of the locking rods (48, 49) and is loaded by the retraction spring (27) of the respective locking unit (60), the catch arm being swiveled by the driver (2) associated therewith from an initial position to a final position when the pertaining pull-out furniture part (1) is pulled out, thereby shifting the actuating part (47) of said locking unit (60).

Description

Extractor for at least two extendable furniture parts

The invention relates to a Ausziehsperrvorrichtung for at least two extendable furniture parts, which consists of a furniture body of a complete

retracted position in a fully extended position in one

Pulling out direction and retractable against the pull-out in the furniture body are retractable, comprising for each of the pull-out furniture part a

Extracting the pull-out furniture part in the pull-out and when retracting the pull-out furniture part against the pull-out shifted

Toggle, for each of the pull-out furniture parts a locking unit, which is a by the movement of the driver when pulling out and retracting one of the

extendable furniture parts verstelles actuating member and a pull-in spring, from which the respective associated extendable furniture part is retractable over a last section of his traversed in the furniture body path, cooperating with the actuating elements locking rods which are slidably mounted in the direction of their longitudinal axes, wherein a respective by the movement of the associated driver when pulling out the associated pull-out furniture part adjusted actuating part at least one of

Locking rods displaced in the direction of its longitudinal axis and thereby the locking bars are blocked by a stop against further axial displacement. By pull-out locking devices, simultaneous pulling out of two or more by the pull-out locking device is coupled to each other

extendible furniture parts, e.g. one above the other arranged drawers prevented. The extendable furniture parts are therefore only alternately extendable. A central locking is often realized on such Ausziehsperrvorrichtungen.

In a conventional embodiment, such a pull-out device

Barrier bars, which have limited space for their displacement exhibit. 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 by the corresponding operating part. The space for the displacement of the locking rods is used up and the locking bars are blocked by a stop against further displacement. Another one

pull-out furniture part can not be pulled out at the same time.

Ausziehsperrvorrichtungen with locking rods are in different

Embodiments known. For example, DE 29 620 152 U1, EP 1 336709 A1 and WO 2008/107499 A1 show an actuation of the locking rods

Operating parts which are pivoted when pulling out of the respective extendable furniture part from the driver about a perpendicular to the longitudinal axes of the locking rods pivot axis. Apart from the operating part, which is the displacement of the farthest from the stop

Locking rod is provided, the operating parts are each between two of the locking rods and are arranged together with these slidably. Ausziehsperrvorrichtungen trained in a similar manner, but here the actuating parts are pivotable about axes which are parallel to the longitudinal axes of the

Locking rods lie, are known from DE 3431 386 C2, DE 93 11 534 U1 and DE 43 25 920 C2.

GB 2376043 A shows a Ausziehsperrvorrichtung, in which with the

Locking rods cooperating actuating parts are pivotable about pivot axes lying parallel to the longitudinal axes of the actuating rods. The

Actuators are provided with radially projecting extensions which form tentacles which are actuated by the attached to the pull-out furniture parts drivers. When you take off one of the extendable furniture parts of the tentacle from the driver of an initial position in an end position

pivoted, wherein a portion of the tentacle retracts into a recess and locked in this, which is provided in a respective housing. The housings store the locking bars displaceable. The rotatable mounting of the operating parts and with them the tentacle arms are formed by axial projections of the operating parts received by axial openings in end portions of the locking bars. EP 1 500 763 A2 discloses a pull-out locking device of the type mentioned in the introduction, which is combined with a pull-in device. Retractors (also called Selbsteinzüge or feed mechanisms) serve a

retractable furniture over a final section of his Einfahrweges automatically and so ensure the fully retracted state of the pull-out furniture part. In the device known from EP 1 500 763 A2, the actuating parts cooperating with the locking rods are formed by carriages mounted in a linearly displaceable manner. These slides are each acted upon by a collection spring, which is stretched when moving the carriage from the initial position to the end position of the carriage. On the carriage, a tilting part is mounted pivotably about a parallel to the locking rods lying, with the carriage mitbewegte axis. When you take off one of the extendable Möbelteiie engages the driver in the tilting part and takes the tilting part and thus the carriage with until the carriage reaches its end position, the tilting tilted, whereby the driver can extend and a locking of the carriage is achieved in the final position , When retracting the extendable

Furniture part of the incoming driver pivots back the tilting part, whereby the driver couples to the tilting part and the latching of the carriage is canceled in the end position, so that the carriage is pulled by the intake spring in the direction of its initial position. The movement of the carriage is damped here by a damper, which is formed by a piston-cylinder unit.

Retractors with and without damping devices are known from a variety of other publications. For example, from AT 401334 B, a feed mechanism emerges in which one against the force of a spring

slidable tilt 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. In the case of AT 393948 B Known retraction device 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 pitch. Another damped retractor, wherein the

Tilting slide cooperates with a insertion damper, is known for example from EP 1 532 892 A1. 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 EP 1 384 420 B1 a retraction device is kinked with one

formed around a stationary horizontal axis rotatably mounted arm, which is acted upon by a pull-in spring, which is integrated in a damper forming a piston-cylinder unit. At the back of the

extendable furniture part a cooperating with the tentacle driver is arranged, which has a slide track. When pulling out the pull-out furniture part of the arm is pivoted starting from an initial position about the horizontal axis in an end position in which the driver decouples from the arm. When pivoting the arm from the initial position in the

End position is overrun by a dead center of the intake spring.

From GB 1,117,071 shows a locking device, 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

Initial position and the end position is pivoted. The spring is moved over a dead center.

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

Damping the Einfahnbewegung of movably mounted furniture parts, for example, from DE 202005020820 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 a highly viscous damping medium is arranged. The braking force is caused by this sheared damping medium. Dampers of this type are described, for example, in DE 10210917 C1, US Pat. No. 5,277,282 A, JP 59-222631 A and US Pat. No. 5,143,432 A.

Furthermore, purely mechanically acting friction damper are known. Thus, for example, DE 19938626 A1, DE 201 16 197 U1 and JP 01-266331 A disclose loop parts which surround an inner friction part and form a friction pairing with it. Friction dampers have the disadvantage that the braking force exerted by them is basically independent of speed.

DE 10313659 B3, DE 10 214 596 A1, DE 19 717 937 A1, AT 503877 B1 and EP 1 260 159 A2 disclose piston-cylinder units in which an air pressure difference which forms between the two piston sides acts on an elastically deformable piston part acts, so that the applied frictional force of the

Air pressure difference and thus depends on the speed of the component to be damped. A vehicle shock absorber in which a flexibler trained

Umschlingungsteil rubbing against an inner friction formed by a friction drum, it is apparent from 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. The object of the invention is to provide an improved pull-out locking device of the type mentioned with integrated retraction device. According to the invention, this is achieved by a Ausziehsperrvorrichtung with the features of claim 1. In the Ausziehsperrvorrichtung the invention, each of the locking units one to a stationary, parallel to the longitudinal axes of the locking rods lying

Pivot axis pivotally mounted tentacle on which of the pull-in spring this blocking unit is acted upon. The tentacle is the associated driver (that's the one who interacts with this tentacle) when

Extracting the associated pull-out furniture part (which is the one with which this driver moves when pulling out and retracting) of a

Starting position pivoted to an end position when the corresponding extendable furniture part is extended from its fully retracted position to its fully extended position or the driver is moved by a corresponding way. If the driver has pulled the tentacle arm from its initial to its end position when pulling out the pull-out furniture part, the driver disconnects on further extension of the extendable furniture part from the tentacle.

When pivoting the respective Fanganns from its initial position to the end position of the tentacle adjusted the operating part directly or indirectly via at least one transmission member. Preferably, the

Operating part to a separate from the tentacle, with this directly or via the at least one transmission member coupled component. A one-piece training with the tentacle is conceivable and possible.

The invention enables a compact and stable design. In this case, a suitable for heavy duty training is also possible. For heavy-duty pull-out furniture parts are provided, of which one, several or all are loaded with more than 150kg.

In particular, the locking bars comprise between the actuating parts

extending locking rods and a locking bar extending between the operating part of those locking unit, which is associated with one of the edge-side pull-out furniture parts, and the stop, wherein all the locking rods are displaced together with the intermediate actuating stiffeners. A catch spring acting upon a respective catch arm is stretched more in the end position of the catching arm than in the initial position of the catching arm.

Preferably, during the pivoting of the tentacle arm from its initial position to its end position, a dead center of the withdrawal spring is overcome. The tentacle is thus held by the feeder spring in its final position after the cooperating with the tentacle driver when pulling out the extendable

Furniture part has disconnected from the tentacle.

Advantageously, a respective tentacle of a stationary (= with the

Furniture body rigidly connected or connectable) bearing unit of the respective locking unit rotatably mounted, which also slidably supports at least one of the locking bars. Conveniently, a respective bearing unit for this purpose has a bearing unit in the direction of the longitudinal axes of the locking rods, ie in the direction of the pivot axis of the tentacle, completely penetrating cavity. Each cavity receives a portion of at least one of the locking bars. In this way, a particularly compact training is possible.

Conveniently, the tentacle is rotatably mounted on at least one surface of the storage unit surrounding the cavity. In an advantageous embodiment of the invention, the

Ausziehsperrvorrichtung a damping device for damping the

Insertion of a respective extendable furniture part, wherein the pivoting of the tentacle arm from the end position to the initial position by this

Damping device is damped. 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 driven by the tentacle during pivoting of the tentacle from its end position in the initial position part which is rotated to exercise a braking force during pivoting of the tentacle from its end position in its initial position relative to a detained part about the stationary pivot axis of the tentacle. It can thereby be an advantageous, very compact training Einziehsperrvorrichtung be achieved with an integrated damped self-closing, with a suitable training for high loads is made possible.

The furniture in which the Ausziehsperrvorrichtung is used, in addition to the pull-out furniture parts for which the Ausziehsperrvorrichtung is used, have one or more other extendable furniture parts that are not coupled to the Ausziehsperrvorrichtung, so are independently extendable, whether already other pull-out furniture part of the furniture is pulled out.

An embodiment of a device according to the invention is shown in FIGS. 1 to 20. The device serves to form a

Pull-out device for pull-out furniture parts designed in the form of drawers 1. A device according to the invention can also be described as

Ausziehsperrvorrichtung be formed for other types of extendable furniture parts, e.g. for tall cabinet extensions.

The pull-out furniture parts 1 can be pulled out of the (not shown in FIGS. 1 and 2 indicated by dashed lines) furniture carcass 30 and not pulled out in the drawing extension guides in a pull-out direction 44 and retracted against the pull-out 44 into the furniture body 30. At the back (relative to the pull-out 44) of a respective extendable furniture part 1, a driver 2 is attached to this, which is thus at

Pulling out and retracting the extendable furniture part 1 with this moved. The device comprises for each of the extendable Möbefteile 1 a respective locking unit 60, that is, it is for each of (in the Ausziehsperrvorrichtung

integrated) furniture parts own (= separate) locking unit 60 available. In the exemplary embodiment, the locking units 60 are attached to a mounted on the furniture body 30 mounting rail 29. A direct attachment of the respective locking unit 60 on the furniture body 30 would be conceivable and possible.

Each of the barrier units 60 has a catching arm 5 mounted pivotably about a stationary ( ^" fixed with respect to the furniture body 30) pivot axis 6. A respective tentacle 5 cooperates with the associated driver 2, in the embodiment shown by cam tracks 3 formed on the driver 2 and projections arranged on the tentacles and formed by rollers 4

Driver 2 is in this case formed U-shaped and has at opposite, on both sides of a connecting leg 2c projecting side walls 2a, 2b, the opposite slide tracks 3, which cooperate with the two projections. Also, a single co-operating with a projection 4 of the driver 2 slide track 3 could be provided. The at least one projection could also be formed by a pin. A reverse training is possible in which at least one slide track 3 on the catch arm 5 and at least one projection 4 on the driver 2 is provided.

In the fully retracted state of each of the pull-out furniture parts 1 takes the respectively associated tentacle 5 its initial position. At the

Extracting one of the extendable furniture parts 1, the associated tentacle 5 is pivoted in the direction of rotation 26a about the pivot axis 6 until it reaches its end position. In this position of the tentacle 5, the driver 2 decoupled from the tentacle 5. The extendable furniture part 1 can be further extended in the sequence until it reaches its fully extended position When inserting the

extendable furniture part 1 in the direction opposite to the withdrawal direction 44 of the driver 2 runs to the located in its end position tentacle 5 at. It then follows a mutual coupling, these two parts and a turning back of the Fangarms 5 in the opposite direction of rotation 26b about the pivot axis 6 until the tentacle 5 again assumes the initial position and the extendable furniture part 1 assumes its fully retracted position. Also trained in other form driving compounds, for example, a substantially V-shaped recess, in which a projection enters to adjust the catch arm 5 from the driver 2 between the initial position and the end position and back, are possible. Different types of possible driving connections are known, for example, from conventional pull-out furniture parts with Einziehmechaniken ago.

In the coupled state of the tentacle 5 with the driver 2 is a positive connection between these two parts based on the

Extraction direction 44 and the opposite direction of insertion.

Fig. 1 shows the state in which all extendable furniture parts 1 occupy their fully retracted position. Fig. 2 shows the state in which one of the extendable furniture parts 1 is extended at least so far that the driver 2 has disconnected from the tentacle 5 and the tentacle 5 is in its final position. The tentacles 5 are in this case coupled such that a pivoting of the other, located in their initial positions tentacles 5 is blocked around the pivot axis 6 in the direction of their end positions. The other extendable furniture parts 1 are thus complete in their

blocked positions retracted. One of the other extendable furniture parts 1 can only be pulled out after the solid furniture part 1 has been retracted again. This coupling of the tentacles 5, through which only one of the extendable furniture parts 1 can always be pulled out at the same time (i.e., the pull-out furniture parts 1 are alternately extendable) will be explained in more detail below.

In the Ausziehsperrvorrichtung invention are retracting devices for the telescoping device coupled together by the extendable furniture parts 1 integrated. By means of these pull-in devices, a respective one of the pull-out furniture parts 1 is automatically pulled in during retraction via a last section of its insertion path. For this purpose, on the one hand on the tentacle 5 and on the other hand engages a non-rotatably and non-rotatably disposed relative to the furniture body 30 part in the

Embodiment, the housing part 28, a pull-in spring 27 at. The housing part 28 is rotatably connected to the mounting rail 29, which in turn is rigid on

Furniture carcass 30 is mounted. A direct mounting of the housing part 28 on

Furniture carcass 30 is possible.

For connection of the pull-in spring 27 with the housing part 28, for example latching arms 43 may be arranged on the housing part 28, between which the inner (closer to the pivot axis 6 located) end of the pull-in spring 27 can be engaged. When the pull-in spring 27 at different distances from the

Swivel axis 6 can be connected to the housing part 28 by

For example, a plurality of latching arms 43 are provided, the strength of the

Retracting force can be changed by different bias voltages of the spring 27. Also connection possibilities at different locations of the tentacle 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 tentacle 5 in the direction of rotation 26a, starting from its initial position shown in Fig. 15 in the direction of its end position, the pull-in spring 27 is first stretched, see. Fig. 15 and 14. Shortly before reaching the end position, a dead center is crossed (this is the one shown in Fig. 14

Position), as a result of which the pull-in spring 27 is again slightly relaxed (preferably less than one fifth of the preceding compression stroke) until the end position shown in FIG. 13 is reached.

When inserting the pull-out furniture part of the driver 2 to the Tentacle 5 starts, so the driver 2 pivots the tentacle 5 in the

Direction of rotation 26b over the dead center of the pull-in spring 27. In the position of the catching arm 5, in which the dead center of the pull-in spring 27 is present, is the

at least one projection 4 has already run so far into the at least one slide track 3, that in another, caused by the pull-in spring 27

Pivoting the tentacle 5 about the pivot axis 6 of the tentacle 5 relative to the withdrawal direction 44 is positively connected to the driver 2 and the extendable furniture part 1 is retracted by the tentacle 5 by the force of the collection spring 27 until the initial position of the tentacle shown in Fig. 15 5 is reached.

Upon pivoting of the catching arm 5 in the direction of rotation 26a, further pivoting of the catching arm 5 in this direction 26a upon reaching the end position is blocked by a stop formed between the catching arm 5 and a body-fixed part, for example the mounting rail 29. In the reverse pivoting of the tentacle, another corresponding stop between the tentacle 5 and a corpus-fixed part, such as

Mounting rail 29, be present, which blocks the further pivoting in this direction of rotation 26b in the initial position of the tentacle. On the other hand, the further pivoting of the tentacle 5 could also be limited by the limitation of the further displacement of the extendable furniture part 1 upon reaching its fully retracted position.

The rotation of the tentacle 5 about the pivot axis 6 of the end position in its initial position, ie in the direction of rotation 26 b, is damped by a damping device described below, which is also integrated in the Ausziehsperrvorrichtung in the embodiment, as is preferred. When starting in the direction of the pull-44 opposite direction

shifted extendable furniture part to those in its final position itself

located tentacle 5 is thus exerted on the pull-out furniture part 1 a braking force. After pivoting the tentacle 5 over the dead center of Pull-in spring 27, the retraction of the pull-out furniture part 1 takes place against the force exerted by the damping device braking force.

The Ausziehsperrvorrichtung further comprises locking rods 48, 49 which are actuated by operating parts 47 of the locking units 60.

The locking bars 48 each extend between the adjacent ones

extendable furniture wedges 1 associated locking units 60. Between the one of the end-side extendable furniture parts 1, in the illustrated embodiment, the uppermost extendable furniture part 1, associated locking unit 60 and a

Stop 59, which is arranged stationary 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 locking unit 60 in a direction away from the other locking units 60 direction.

Trained in another form or cooperating with the tentacles 5 operating parts 47 are conceivable and possible. An example of such another possible embodiment will be explained in more detail below with reference to FIGS. 21 to 24.

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. The longitudinal axes of all locking rods 48, 49 are parallel to each other and on a common line on which the pivot axes are 6, i. the

Longitudinal axes of the locking rods 48, 49 and the pivot axes 6 coincide.

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. The pull-out of one of the pull-out furniture parts 1 from the tentacle 5, which is pivoted when pulling out this extendable furniture part 1, adjusted operating member 47 shifts all seen from him closer to the stop 59 lying

Locking rods 48, 49 with the intermediate operating parts 47th

together.

In the embodiment, a respective actuating part 47 in the form of a

Cam disc formed and rotationally fixed to the tentacle 5 of the respective

Locking unit 60 connected. The actuating member 47 can in this case be moved relative to the tentacle 5 in the direction of the pivot axis 6 by a limited distance, while still remaining in rotationally fixed connection with the tentacle 5. For example, for this purpose, the tentacle 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 portions 48a, the locking rods 48 each have one (e.g., by being supported on the

Mounting rail 29) rotatably held cam follower part 50. At the upper ends of the rod parts 48a, the locking rods 48 each have a non-rotatably held cam follower part 51 (in the exemplary embodiment, this has radially projecting, extending in the axial direction webs, which in in axial

Direction extending recesses engage the inner brake member 10). At the end of the rod part 49a of the locking rod 49 facing the locking unit 60, a cam follower part 50 is arranged, which (for example by being supported on the

Mounting rail 29) is held against rotation.

If one of the pull-out furniture parts 1 pulled out, so is by the

Pivoting the tentacle 5 of the associated locking unit 60 of the initial position in the end position of the actuating member 47 of this locking unit 60 stiffened from a first to a second position, causing 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. Is it the one cooperating with the locking bar 49 Operating member 47, so only the locking rod 49 is displaced in the direction of the stop 59 until the existing game is at least substantially used up (the distance a, see Fig. 7, has decreased to less than one fifth of the initial value). Was another pulled out of the pull-out furniture parts 1, 60 are all of the actuating member 47 of the associated locking unit 60 all located between the actuating member 47 and the stop 59 locking rods 48, 49 and lying between the locking rods 48, 49 operating parts 47 are displaced in the direction of the stop. In Fig. 8, the shift distance s (which is at least four-fifths of the initial value of the distance a) is indicated at three places.

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 tentacles 5 of the other extendable furniture parts 1 are thus blocked in their initial positions, so that a

Displacement of the associated driver 2 is blocked in the pull-out 44.

When retracting the extended pull-out furniture part 1 of the associated tentacle 5 is stiffened from its final position to its initial position and this adjusts the operating member 47 of this locking unit 60 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 slidably disposed so that this locking unit 60 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 belonging to the extendable to this furniture part 1 Operating member 47 extends upward, and all optionally overlying locking rods 48, 49 and intermediate actuation parts 47 moved 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 lowest extendable furniture part 1 associated locking unit 60 and the locking bar 49 extends between this locking unit 60 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. In principle conceivable and possible are inclined relative to the horizontal arrangements of the locking rods 48, 49 and the pivot axes. 6

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).

17 and 18, the positions of a locking unit 60 are compared when the corresponding pull-out furniture part 1 is retracted, in Fig. 17 and the retractable furniture parts are retracted, the locking units are assigned, which are further away from the stop 59, while in Fig. 18 one of these extendable furniture parts is pulled out. In Fig. 19, the state in the extended position of the associated pull-out furniture part 1 is 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 intermediate space between the locking rod 49 and the stop 59, which is a Displacement of the locking rods 48, 49 and the intermediate operating parts 47 in the direction of the stop 59 blocked.

The tentacle 5 is pivotally supported by a stationary bearing unit about the axis of rotation 9, wherein the tentacle 5 is held immovably in the direction of the pivot axis 6 of the tentacle 5. The stationary storage unit is in

Embodiment of the housing part 28 and an inner brake member 10 is formed, on which the housing part 28 is placed. The stationary bearing unit is rotatably connected in the embodiment with the mounting rail 29, which in turn is attached to the furniture body 30. The attachment to the mounting rail 29 is preferably carried out by latching projections of the housing part 28 and the inner brake member 10, which engage in recesses in the mounting rail 29. An elimination of the mounting rail 29 and an attachment directly to the furniture body 30 is conceivable and possible.

The stationary bearing units support the locking bars in their axial directions. For this they have a completely penetrating, 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.

For pivotable mounting of the catching arm 5, this is rotatably mounted in the embodiment on the cavity 46 surrounding surfaces of the stationary bearing unit.

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 can be inserted into the cavity 46 with the extension 51a, and the cam follower part 50 can be inserted with the extension 50a through a central opening of the actuation part 47 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 damping device comprises in the illustrated embodiment, a first, mechanically acting brake device with two against each other around the

Pivot axis 6 twisted parts {= first rotation damper) and a second brake device coupled thereto, the braking force of a in a gap between two against each other about the pivot axis 6 twisted 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 tentacle 5 is connected to a preformed, but flexible by its elasticity Umschlingungsteil 31, so that the Umschlingungsteil 31 at a

Rotation of the tentacle 5 is also rotated about the pivot axis 6 in the direction of rotation 26b about the pivot axis 6. The wrap-around part 31 is in

Embodiment formed by a band and extends around a major part of the circumference of the inner brake member 10 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 inner brake member 10 which forms a fixed friction surface 15 (in the embodiment, this is the lower portion of the wall 40). The driven friction surface 14 and the retained friction surface 15 form the friction pairing of the first, mechanically acting

Braking device comprising the wrap member 31 and the inner brake member 10. The connection of the tentacle 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. 10a. Other trainings of the

Carrier connection are possible. Between the front connection point 33 and the rear connection parts 34, the wrap-around part 31 extends over more than 90 °, preferably over more than 180 °, particularly preferably over more than 250 ° with respect to the pivot axis 6 about the inner brake part 10 (in the direction of rotation 26a ). Im shown

Embodiment, this extension is less than 360 °. An extension of more than 360 ° is possible, i. the wrap-around part then has more than one complete turn, wherein it runs helically around the inner brake part 10.

The rear connection point 34 of the wrap 31 is over a

Open holding spring 25 connected to the tentacle 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 inner brake member 10. Furthermore, the damper sleeve 18 has a wall 38 which engages over an upper portion of the outer wall 40 of the inner brake member 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 8 form driven damper surfaces 21. The outer surface of the wall 39 of the inner brake member 10, the inner surface of the wall 40 of the inner brake member 10 and the upper portion of the outer surface of the wall 40 of the inner brake 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 Spart, 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 inner

Brake part 0 and the damping medium 23. By the rotation of the tentacle 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 this around the Swivel axis 6 is rotated. 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 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. Due to its preforming in the state of rest, the wrap-around part 31 preferably has at least substantially the entire course of its course

Friction surface 14, i. at least over 90% of its extent in the circumferential direction, a distance from the friction surface 15 of the inner brake member 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 acted upon the catch arm 5 in the direction of rotation 26b, the friction surface 14 of the wrap 31 is then up to a limit of the speed of the pull-out furniture part 1 and a

Limit value of the rotational speed of the tentacle 5 from the friction surface 15 of the inner brake member 10 spaced (at least in large part) and the first

Braking device is essentially ineffective {d. H. 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 extendable furniture part 1 impinges on the tentacle 5, it would without the overload spring 32 to a sudden

occurring high braking force of the device, which would 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 top of the Braking force cushioned by the tentacle 5 against 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, possibly after damping of the first faster

Speed of the pull-out furniture part 1 when starting against the tentacle, is relatively low must be overcome by the intake spring 27 substantially 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 catching arm 5 in the direction of rotation 26a, the damper sleeve 18 is rotated by the catching arm 5 via the hold-open spring 25, so that the force to be overcome in this case is to be exerted. This force is comparatively low, since the first brake device is not effective in this direction of rotation. If the

However, application of such a force is not desired, a freewheel can be provided between a part connected to the wrap-around part 31, possibly via the hold-open spring 25 and / or the overload spring 32, and the catching arm 5, which is closed in the direction of rotation 26b and engages in the opposite direction of rotation 26a opens. Such freewheel are known, also in connection with dampers.

In a comparison with the illustrated embodiment modified

Embodiment, the tentacle 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 take place on the catching arm 5 radially outside this axis of rotation. By a return spring of the tentacle 5 in a

Be charged 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 tentacle 5 is pivoted more or less 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 tentacle 5 and a corpus-fixed part, such as the

To arrange housing part 28. The actuating member 47 would then be coupled in another way with the tentacle 5, for example via the damper sleeve 18, which in its rotation, the actuating member 47 directly or at least one

The transfer element 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 favorably between 90 ° and 530 °, preferably between 180 ° and 500 °, wherein a wrap angle between 250 ° and 330 ° is particularly preferred.

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 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 entry of one of the projections 4 of the Einziehhebels 5 in the associated

Sliding track 3 of the driver 2 when closing the pull-out furniture part 1 is shown in Fig. 20. The curved slide track 3 (the course of both cam tracks 3 is identical) has a beginning portion 3a, at the beginning the projection 4 from outside the slide track 3 enters the slide track 3. Via the initial section 3a, the slide track 3 guides the projection 4 in a direction 57 which encloses an angle α of less than 30 ° with the pull-out direction 44. In this case, the angle α increases continuously from the beginning of the starting section 3a, at which this angle α is preferably less than 20 °, particularly preferably less than 15 °, to the end of the starting section 3a. The end of the initial section 3 a and the beginning of a continuation section 3 b of the slide track 3 are thus where this angle α reaches the value of 30 °. By way of the continuation section 3b, this angle α continues to increase until, in any case, it is more than 45 °, in the embodiment shown between 80 ° and 90 °. In Fig. 20, the angle α for a position of the projection 4 is within the

Continuation section 3b located in which the angle α is slightly more than 45 °. In the illustrated embodiment, the angle α, as soon as it reaches its maximum

Has reached value until the end of the continuation section 3b constant. Also, a curved configuration of the link 3 to the remote from the initial section 3a end of the continuation section 3b is possible in other embodiments.

The projection 4 is guided by the slide track 3 thus at least over a subsequent to the beginning of the initial portion 3a portion of the starting portion of the slide track 3 at an angle of less than 20 °, preferably less than 15 ° to the pull-44. At least part of the

Continuation section 3b, the projection 4 is preferably guided by the slide track 3 in a direction which forms an angle of more than 70 °, preferably more than 80 °, with the pull-out direction 44.

In Fig. 20, three positions of the projection 4 when entering the slide track 3 are shown with dashed lines. The first position shows the first one

Starting the projection 4 to the side wall 45 of the slide track 3, through which the Einziehhebel 5 is pivoted over the dead center (this side wall 45 is then in the continuation section 3b, relative to the pull-out direction 44 opposite insertion direction of the furniture part 1 rear side wall of the slide track 3). The angle α is here less than 20 °, preferably less than 10 °, In the second position, the projection 4 is already in the continuation section 3b, in which case the angle α is just greater than 45 °. In the third position shown, the projection 4 is in

Continuation portion 3b at the point he occupies in the fully inserted state of the extendable furniture part, the angle α here in

Embodiment between 80 ° and 90 °. The side wall 45 extends in each case in the direction in which the projection 4 is guided by the slide track 3, so that the angle which the side wall 45 includes in each case with the withdrawal direction 44, the angle α between the direction of the guide of the projection 4 and the

Extraction direction 44 corresponds. As a result of the described curved course of the at least one slide track 3, the force required to actuate the catching arm 5 can be influenced during the insertion of the extendable furniture part 1. In particular, results from the course of the inlet section 3a a kind of translation. The acting on the pull-out furniture part 1 damping force is characterized when the extendable

Furniture part 1 starts at a certain speed to the tentacle 5, at the beginning of startup, when the projection 4 is in the region of the inlet section 3a of the slide track 3, reduced. Furthermore, the dead center of the pull-in spring 27 (if there is one) can thereby be overcome by a smaller force to be applied by the pull-out furniture part 1.

From Fig. 20 is further a self-healing section 3c of the slide track 3 shows. By this, the respective projection 4 can enter the continuation section 3b when the driver 2 should start when inserting the pull-out furniture part to the in its basic position located Einziehhebel 5. Of the

Self-healing section extends at least substantially (ie, a deviation of less than 15 ° is present) parallel to the withdrawal direction 44. The self-healing sections 3c are widened towards their open ends by inlet slopes. With it Retraction of the projections 4 by the self-healing sections 3 c is made possible, the projections 4 but not by the self-healing sections 3 c of the

Continuation sections 3b can leak, the elasticities of the components can be exploited {so that the projection 4 as shown in Fig. 20 in the retracted state of the extendable furniture part 1 is offset from the self-healing section 3c).

For example, could also be provided when driving in the projections 4 by the self-healing sections 3c, a driving over of steps, wherein the

Slide tracks 3 having side walls 2a, 2b are pressed apart. Additionally or instead could be provided on the driver 2 arranged, additional resilient locking elements.

The operation of the locking rods 48, 49 could also be done in other ways. Such another possible embodiment is shown in FIGS. 21 to 24. 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 operating member 47 has a Betätigungsann 47 a, 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 tentacle 5 or another part which rotates about the pivot axis 6 when the tentacle 5 around the

Swivel axis 6 is rotated, for example, with the damper sleeve 18. Also a one-piece design with the tentacle 5 or rotated about the pivot axis 6 part, for example, the damper sleeve 18 is possible.

In principle conceivable and possible are inclined relative to the horizontal arrangements of the locking rods 49 and the pivot axis. 6

In the figures described above, a bent leaf spring is provided as a pull-in spring. Also trained in other ways catch springs can 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 described in other ways than

be educated. Thus, instead of the described belt part, a type of belt unit could also be provided, which is formed by two or more articulated, rigid shoe parts which surround the inner brake part at least over a large part of its circumference. At one with respect to the direction of rotation about the pivot axis 6 end side jaw member (which is based on the direction of rotation 26b front) of the tentacle 5 could be attached, whereby the tentacle 5 could be pivotally mounted about the pivot axis 6. With a relative to the direction of rotation 26b back jaw member, the damper sleeve 18 may be rotatably connected. By the force exerted by the viscous damping medium on the damper sleeve braking action, the jaw member are more or less compressed and pressed against the inner brake member 10. Also 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 if the braking force achieved thereby is sufficient.

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

The driver could also be fixed to a attached to the extendable furniture part 1 carcass-resistant mounting rail a pull-out for the pull-out furniture part.

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. In the illustrated embodiment, all extendable furniture parts of the furniture are integrated into the pull-out device. But there are also training possible in which the furniture additionally has at least one extendable furniture part, which is independent of whether one of the other extendable furniture parts of the furniture is already pulled out, pulled out. Such a furniture part which can be pulled out independently of the other pull-out furniture parts is often the uppermost of several drawers, which can have a low storage volume and thus a low possible loading weight, e.g. a drawer for writing utensils.

In a non-extendable by the pull-out device furniture part can be used instead of a blocking unit 60, a unit that no

Actuating member 47 has, but otherwise in the same or at least analogous manner as the locking unit 60 may be formed. Such a unit therefore has one stationary bearing unit having a completely penetrating cavity corresponding to the cavity 46. Through this cavity, one of the locking rods 48 or 49 may extend. Thus, it is possible to realize the function of Selbsteinzuges and damping with the same parts, but to exclude one or more extendable furniture parts of the furniture of the lock function of the pull-out device.
