Such damping devices are already known. the WO 2007/017688 A1 discloses an extendable armrest with a guide carriage, of which an upper carriage part is connected to the extendable armrest and a lower carriage part is fixed in place. A motion damping device is provided which has a roller made of plastic material which is rotatably fixed to the lower, stationary carriage part. When the armrest is extended, the upper carriage part slides over the roller, with ramp-like segments being formed on the upper carriage part, each of which has bevels bent downwards, so that they cause a jamming with the roller when it is driven onto it.

the DE 198 24 167 A1 discloses a telescopic pull-out device for furniture and household appliances, in which a braking device with a brake shoe acts between two rails of a guide device, which is pressed onto a brake sliding surface by means of a spring, the braking effect being either over the entire extension length or only over one or more partial areas of this Extension length can be caused more or less strongly.

the EP 1 275 325 A1 discloses a braking device for braking the retraction or extension movement of an extendable furniture part. A braking device is provided for braking the movement of a running rail of a drawer when the drawer is moved into the open position. For this purpose, a ramp loaded by means of spring means is provided on the cabinet rail, which ramp is run over when the drawer is pulled out, as a result of which a braking effect is achieved.

In the EP 1 743 550 A1 an automatic displacement mechanism for furniture pull-outs is described, in which the retraction of a drawer into the open position is dampened by a damping device. The damping device comprises a fluidic damper with a damper housing in which a damper piston is guided so that it can be displaced linearly. The damper piston is connected to a piston rod leading out of the damper housing, which absorbs the movement when moving into the open position and thereby causes the damper piston to move in a damping medium in the damper housing, thereby braking or damping the opening movement.Object of the invention is to create a damping device of the type mentioned which is simple in construction, inexpensive to produce and reliable to handle.

the DE 80 13 283 U1 discloses a pull-out guide for pull-out furniture parts, in which the carcass rail and the pull-out rail enclose an upper and lower running channel for rolling elements and in at least one of the end positions of the pull-out rail a friction brake is effective between the carcass rail and the pull-out rail.

the DE 37 16 923 A1 discloses a pull-out guide in which an elastically deformable braking element is provided on the essentially horizontal profile section of a guide rail next to the running rail and a projection that moves against the elastic braking element in the intended braking position is provided on a lateral shoulder of the running rail.

the DE 20 2004 001 794 U1 discloses a damping device for braking movable masses, for example furniture drawers, with an elongate, sleeve-like or tubular damping housing, a damping element arranged in the damping housing and wound up in the manner of a spiral spring and made of a material with resilient resilience, a damping tongue that can be moved into and out of the damping housing, which acts against the damping element when immersed in the damping housing and completely or partially rolls it up and stretches it elastically.

the DE 299 16 841 U1 discloses a guide fitting for an element that can be pulled out of the front of a piece of furniture, which element has a so-called self-closing function, the guide fitting being equipped with a damper. The object of the invention is to create a damping device of the type mentioned at the outset that is simple in construction, inexpensive to produce and reliable to handle.

This object is solved by a damping device having the features of independent claim 1 . Further developments of the invention are presented in the dependent claims. The damping device according to the invention is characterized in that the clamping unit has at least one clamping element, which is movably mounted on the clamping unit between a basic position and a clamping position and which, in its clamping position, narrows the width of the clamping gap in such a way that the clamping piece is between itself and a likewise formed on the clamping unit Abutment part is clamped, the clamping element being designed as a rollable clamping roller on a rising in the direction of entry of the clamping piece inclined surface, the running surface protrudes a little into the clamping gap, as a result of which the running surface can be run over by the clamping piece, which causes the overridden clamping roller to move upwards on the associated inclined surface into the clamping position, and with several clamping rollers arranged one behind the other in the entry direction of the clamping piece and being able to be driven over one after the other are.

The damping device is designed to act mechanically due to the clamping means. As a result, damping media that are used, for example, in fluid dampers of conventional damping devices can be dispensed with.

According to the invention, the clamping means are designed in such a way that they can be dynamically and progressively clamped to one another. It is therefore possible for the clamping effect caused by the clamping means to increase as the open position is approached.

In a development of the invention, the base unit has a carcass rail, which can be fastened or is fastened to the furniture carcass, of a guide device for guiding the movable furniture part in the furniture carcass, the first clamping means being arranged on the carcass rail.

In a particularly preferred manner, the first clamping means are on a front, in arranged near a furniture compartment opening lying mounting interface.

Movable furniture parts within the meaning of the invention can be drawers, doors or flaps.

As an alternative to arranging the first clamping means on the body rail, it would also be conceivable to arrange the first clamping means on the body of a piece of furniture. Here, for example, an assembly interface would be conceivable on the bottom of a drawer receptacle or a drawer compartment, in particular in the front assembly interface located in the vicinity of the compartment opening.

In a development of the invention, the movement unit has at least one running rail of a guide device for guiding the movable furniture part in the furniture body, with the second clamping means being arranged on the running rail. In a particularly preferred manner, the two mutually associated clamping means are arranged on the body rail on the one hand and on the running rail on the other hand.

In the case of a movable furniture part designed as a drawer, the running rail is a drawer rail.

However, it would also be conceivable to arrange the second clamping means on the movable furniture part itself, for example on the drawer, for example there on the bottom of the drawer.

In a particularly preferred manner, the moving unit has at least two running rails, of which at least one running rail is movably guided between the body rail and a further running rail, in particular a drawer rail Center rail is formed. Such a guide device is also referred to as a full extension.

The clamping piece is preferably arranged on the drawer rail and the clamping unit on the body rail or on the furniture body.

It is possible for the clamping piece to be designed in the manner of a plate or strip.

The clamping element is designed as a plurality of clamping rollers, each of which is designed to roll on an inclined surface that rises in the direction of entry of the clamping piece and whose running surface protrudes a little into the clamping gap, as a result of which the running surface can be run over by the clamping piece, which causes the clamping roller that has been run over to move to be shifted upwards into the clamping position on the assigned inclined surface. Due to the clamping of the clamping piece of the at least one clamping roller and the abutment element, the movable furniture part is delimited in the opening direction and can be pulled manually into the end position if necessary.

Several clamping rollers are provided which are arranged one behind the other in the insertion direction of the clamping piece and can be driven over one after the other. This reduces the risk of the clamping piece passing through the clamping gap without jamming occurring if the movement speed of the movable furniture part is too high.

The invention also includes a piece of furniture with at least one movable furniture part, in particular a drawer, which is characterized by a device according to one of claims 1 to 5.

the Figures 1 and 2 show a first exemplary embodiment of the damping device 11, which does not belong to the invention, for damping the opening movement of a movable furniture part 12. The damping device 11 can be used, for example, on a movable furniture part 12 designed as a drawer. It is of course possible to use the damping device 11 on other movable furniture parts, for example a door or a flap.

The invention is described in more detail below using the example of a movable furniture part 12 designed as a drawer.

The damping device 11 has a base unit 14, which has a furniture body 13 of a piece of furniture, and a movement unit 15, which can be moved relative to the base unit 14 and has the furniture part 12.

The drawer is displaceably mounted relative to the furniture body 13 by means of a guide device 16 . The guiding device 16 includes a plurality of guide units 17 associated with opposite side edges of the drawer.

The guide units 17 each have a body rail 18 which is fastened in a fixed position using suitable fastening means on an associated side wall of a drawer receptacle or a drawer compartment formed in the furniture body 13 . The body rail 18 is part of the base unit 14 alongside the furniture body 13.

On the body rail 18, for example, a middle rail 19 is displaceably mounted, on which in turn a running rail 20 is displaceably guided by means of bearing means. The running rail 20, which can also be referred to as a movement rail or in the present case as a drawer rail, is assigned to the drawer and runs below the bottom of the drawer in the depth direction. The combination of cabinet rail 18, middle rail 19 and running rail 20 is called full extension. However, it is also conceivable to use guide units 17 without a center rail 19 .

In order to dampen the movement of the drawer into the open position, the damping device 11 has first damping means 21 associated with the base unit 14 and second damping means 22 associated with the movement unit 15 .

The interaction of the first and second damping means 21, 22 ensures end position damping of the movable furniture part when moving into the open position.

For this purpose, the first damping means 21 have first clamping means, which are therefore assigned to the base unit 14 . Also own the second damping means second clamping means 24 associated with the movement unit 15.

As in particular in the Figures 1 and 2 shown on the basis of the first exemplary embodiment, the first clamping means have a clamping member 25 which is fastened to the carcass rail 18 by means of suitable fastening means.

In the example, the clamping member 25 is accommodated between two ribs of a reinforcing bead 27 formed out of the material of the carcass rail 18 . The reinforcing bead 27 protrudes from a mounting section 26 of the cabinet rail 18 and runs on a bearing section of the cabinet rail 18. The mounting section 26 is fastened to the side wall of the drawer receptacle using suitable fastening means, for example fastening screws. The clamping member 25 has a pressure piece 29 which is spring-loaded by means of spring means. In the example, two compression springs 30 are provided, which are supported on the one hand on the bottom of the reinforcement bead 27 and on the other hand on the pressure piece 29 . The compression springs 30 push the pressure piece 29 outwards out of the reinforcement bead 27 . The pressure piece 29 has a clamping surface 31 on its front side.

The second clamping means 24 have a clamping wedge 32 which is attached to the rear end of the running rail 20 . The clamping wedge 32 is located on the side wall 33 assigned to the mounting section 26 of the carcass rail 18 and protrudes outwards from it. The clamping wedge 32 widens towards the rear end of the running rail 20 , as a result of which the distance between the outer surface of the clamping wedge 32 and the mounting section 26 decreases in the direction towards the rear end of the running rail 20 . The outer surface of the clamping wedge 32 forms a counter-clamping surface 34, which is assigned to the clamping surface 31 on the pressure piece 29.

When opening, the drawer is pulled out of the drawer mount or out of the drawer compartment. When moving into the open position, the counter-clamping surface 34 on the clamping wedge 32 comes into contact with the clamping surface 31 of the pressure piece 29. Since the clamping wedge 32 widens to the rear, the pressure piece is pushed against the spring force of the compression springs 30 into the Reinforcing bead 27 is thus pushed in towards the mounting section 26 . A clamping force acts between the clamping surface 31 and the counter-clamping surface 34, which brakes the opening movement of the running rail and thus of the drawer when it is moved into the open position. This dampens the opening movement. Due to Hoock's law, the clamping wedge 32 and the pressure piece 29 progressively clamp, i.e. the clamping force increases as the open position is approached, since the compression springs 30 are further shortened as they move into the open position, as a result of which the spring force increases.

Figures 3 to 5 show a preferred exemplary embodiment of the damping device 11 according to the invention. Here, too, first clamping means 23 are assigned to the first damping means 21 and second clamping means 24 are assigned to the second damping means 22 . As in particular in figure 3 shown, the first clamping means 23 associated with the base unit 14 have a clamping unit 35 which is fastened to the bottom of the drawer receptacle by means of suitable fastening means, for example fastening screws. Expediently, the front end of the clamping unit 35 essentially borders directly on the drawer compartment opening. The clamping unit can also be connected to the cabinet rail via/on a mounting plate.

As in particular in figure 3 shown, the clamping unit 35 has a base unit 36 which has several functional parts. The base unit 36 has a fastening part 37 which has two through-holes through which fastening screws can be passed and screwed into the bottom of the drawer receptacle for fastening. The fastening part 37 has an upper side 38, on one edge of which an abutment part 39 connected in one piece with the fastening part 37 is attached. The abutment part 39 is designed in the manner of an angle piece, with a first leg 40 extending upwards from the upper side 38 of the fastening part 37 . A second leg 41 attached to the first leg 40 and integrally connected thereto extends from the first leg 40 parallel to the top over part of the top 38. The second leg 41, in particular its underside, and the top 38 of the fastening part 37 together a clamping gap 42.

The clamping unit 35 also has at least one clamping element in the form of a clamping roller 43, which is movably mounted on the clamping unit 35 between a basic position and a clamping position Figures 3 to 5 a first and a second pinch roller 43a, 43b are shown by way of example.

The pinch rollers 43a, 43b are each loosely accommodated in pinch roller receptacles 44a, 44b in the fastening part 37 of the base unit 36 of the clamping unit 35. As in particular in figure 5 shown, the pinch rollers 43a, 43b are freely rotatably mounted in the associated pinch roller mounts 44a, 44b.

As in particular in figure 3 shown, a part of the shell portion of the cylindrical pinch rollers 43a, 43b protrudes over associated slot-shaped openings 45a, 45b into the clamping gap 42.

As in particular in figure 5 shown, the respective clamping roller receptacles 44a, 44b have several functional sections with different functions. The clamping roller receptacles 44a, 44b are each designed in the manner of a slot. They each have an inclined surface 46a, 46b, which extends from the figure 6 illustrated basic position of the clamping roller 43a, 43b increases in the pull-out direction of the drawer. The pinch rollers 43a, 43b can therefore be removed from the figure 5 shown clamping position can be shifted upwards and forwards into the clamping position in which the clamping rollers 43a, 43b each protrude from the associated openings 45a, 45b with a casing section which is larger than in the normal position. The clamping roller receptacles 44a, 44b also have a support section 47a, 47b that is elastically deformable in the manner of a spring and is designed in the manner of a bearing shell, which is effective during the closing movement of the drawer during the backward movement of the clamping rollers from the clamping position to the basic position in the manner described below .

The second clamping means 24 have a clamping piece which, as in particular in figure 3 shown, is arranged at the rear end of the running rail 20 as a plate or strip-shaped element. The clamping piece 48 is arranged laterally on the side wall of the running rail 20 assigned to the clamping unit 35 and can be formed from the material of the running rail 20, for example.

When the drawer is opened, the running rail 20 moves out of the drawer receptacle, with the clamping piece 48 engaging the clamping unit 35 . The clamping piece 48 first runs over the first clamping roller 43a and takes this with. Since the first pinch roller 43a is freely movable in the associated pinch roller receptacle 44a, it is displaced upwards from the basic position into the pinched position by the further movement of the pinch piece 48 on its inclined surface 46a. The clamping piece 48 then runs over the second clamping roller 43b, which, like the first clamping roller 43a, is also carried along and shifted upwards into its clamping position. The two clamping rollers press the clamping piece 48 into contact with the underside of the second leg, that is, with the abutment part 39, ie between the clamping rollers and the underside of the second leg 41, a clamping gap 42 is formed. The clamping piece 48 is clamped in this clamping gap 42, as a result of which the opening movement of the running rail and thus of the drawer is braked.

When the drawer is then closed, the running rail 20 is moved back into the drawer receptacle in the closing direction, as a result of which the clamping piece 48 moves the clamping rollers 43a, 43b back from the clamping position to the basic position. In order for the clamping piece 48 to be free, the respective support sections 47a, 47b bend downwards, as a result of which the clamping rollers 43a, 43b can be displaced downwards a little, so that they can be completely pushed out of the space between the upper side 38 of the fastening part 37 and the second leg 41 be shifted out. This ensures that the clamping piece 48 can be moved back without jamming. If the clamping piece 48 has passed the clamping unit 35 in the closing direction, the elastic support sections 47a, 47b snap back and the clamping rollers 43a, 43b are again in their basic position.

the figures 6 and 7 show a third exemplary embodiment of the damping device 11 according to the invention, which does not belong to the invention.

As in the first exemplary embodiment described above, the first clamping means 23 of the base unit 14 has a clamping member 25 , while the second clamping means 24 of the movement unit 15 has a clamping wedge 32 .

In contrast to the first embodiment, the clamping member is designed as a rotatably mounted clamping roller that can roll on a clamping surface of the clamping wedge 32 . The pinch roller is freely rotatably mounted about an axis of rotation 50 . The axis of rotation 50 is formed by a bearing pin 51, which in turn is fastened to the bottom of the drawer receptacle or to a mounting plate (not shown) fastened there using suitable fastening means.

The clamping wedge 32 is arranged at the rear end of the running rail 20 and protrudes laterally from the side wall of the running rail 20 facing the clamping roller. The clamping wedge 32 has a clamping surface 31 on its outside. The clamping wedge 32 widens in the direction of the rear end of the running rail 20. A gap 52 is formed between the outside of the clamping roller and the side wall is filled in.

The pinch roller can be formed from elastically yielding material, for example rubber-elastic material.

When the drawer is opened, the running rail 20 is moved out of the drawer receptacle. The clamping wedge 32 comes into contact with the pinch roller. The pinch roller comes into contact with the pinch surface 31 of the pinch roller. Due to the further movement of the running rail 20 outwards, an ever wider section of the clamping wedge is displaced into the gap between the clamping roller and the side wall of the running rail, as a result of which the opening movement is slowed down.

the Figures 8 to 10 finally show a fourth embodiment of an exemplary embodiment of the damping device 11.

The clamping means have at least one roller carriage 54 which is movably guided in a running channel 53 between the drawer rail or running rail 20 and the central rail 19. A constriction section 55 which reduces the cross section of the running channel 53 is also provided. The constriction section 55 is formed by a section of material protruding inwards from the center rail into the running channel. When the drawer is opened, the roller carriage 54 is displaced within the running channel 53. When approaching the open position, the roller carriage 54 moves into the constriction section 55 and is clamped there with the side walls of the running channel, causing the opening movement to be braked.

figure 11 shows another exemplary embodiment of the damping device 11 according to the invention, also shown as an example when used on a movable furniture part 12 designed as a drawer. The damping means 22 assigned to the movement unit 15 have a driver 61 for activating the rotary damper.

The driver is designed as a toothed rack, which sits at the rear end on the side wall of the running rail 20 and protrudes inwards from there with its teeth.

The rotation damper 60 is arranged on a mounting plate 63, which in turn is mounted via mounting screws 64 on the bottom of the drawer compartment formed in the furniture body.

The rotary damper 60 has a gear wheel 62 which is mounted such that it can rotate about an axis of rotation and whose rotational movement is braked by a damping medium, for example hydraulic oil.

When the drawer is opened, the toothed rack comes into engagement with the rotary damper 60 in a certain open position of the drawer, which is just before the end stop. The gearwheel is thereby set in rotation and in turn brakes the movement of the running rail and thus the drawer.
