Abstract

Official abstract text for this publication.

A device for holding, braking or accelerating a movable furniture part includes a driver which is movable along a guide path between at least two end positions, and an activator which can be brought into engagement with the driver at a receptacle in order to hold, brake or accelerate a movable furniture part, and can be decoupled from the driver at one of the two end positions. The activator is movable through a guide in the longitudinal direction and is resiliently mounted in a direction perpendicular to the longitudinal direction via a spring element and is movable along a run-up slope on the driver in order to latch on the receptacle behind the run-up slope, wherein the activator can be pretensioned in an engagement position on the driver in the event of a force in the longitudinal direction towards the driver.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A piece of furniture ( 1 ) comprising a furniture body ( 2 ) and a plurality of movable furniture parts ( 3 ), which are guided or held on the furniture body ( 2 ) by a device ( 5 ) that is configured for holding, braking or accelerating the movable furniture parts, the device ( 5 ) comprising: a strip ( 6 ) with several housings ( 7 ), each housing having a guide track and being fixed to the furniture body; a driver ( 16 ) disposed in each housing, and being configured to be moved along a guide path in the guide track between at least two end positions, and an activator ( 12 ) disposed on each one of the movable furniture parts or on a running rail ( 8 ) of a pull-out guide ( 4 ) connected to each one of the movable furniture parts, each activator being configured to be brought into engagement with a corresponding one of the drivers ( 16 ) at a receptacle ( 17 ) in order to hold, brake or accelerate one of the movable furniture parts ( 3 ), and is configured to be decoupled from the corresponding driver ( 16 ) at one of the two end positions, wherein each activator ( 12 ) is movable through a guide in a longitudinal direction and is resiliently mounted in a direction perpendicular to the longitudinal direction via a spring element ( 13 ) and is movable along a run-up slope ( 18 ) on the corresponding driver ( 16 ) in order to latch on the receptacle ( 17 ) behind the run-up slope ( 18 ), wherein each activator ( 12 ) is configured to be pretensioned in an engagement position on the corresponding driver ( 16 ) in the event of a force in the longitudinal direction towards the corresponding driver ( 16 ). 2 . The piece of furniture ( 1 ) according to claim 1 , wherein with an increasing force in the longitudinal direction on one of the activators ( 12 ), the spring element ( 13 ) biases the one activator ( 12 ) more strongly towards the corresponding driver ( 16 ). 3 . The piece of furniture ( 1 ) according to claim 1 , wherein at least one of the activators ( 12 ) is configured to be moved from an initial position with a relaxed spring element ( 13 ) perpendicular to the longitudinal direction in opposite directions. 4 . The piece of furniture ( 1 ) according to claim 1 , wherein at least one of the spring elements ( 13 ) is designed as a leaf spring and at least one leg ( 14 , 15 ) of the leaf spring extends from at least one of the activators ( 12 ) essentially in the longitudinal direction counter to the direction of action of the force in the longitudinal direction. 5 . The piece of furniture ( 1 ) according to claim 4 , wherein the at least one leg ( 14 , 15 ) has at least one section which is aligned at an angle to the longitudinal direction. 6 . The piece of furniture ( 1 ) according to claim 1 , wherein at least one of the spring elements ( 13 ) is web-shaped and/or U-shaped. 7 . The piece of furniture ( 1 ) according to claim 4 , wherein at least one stop ( 20 , 30 ) is arranged on the at least one spring element ( 13 ), which stop limits the deflection of the leg ( 14 ) carrying the activator ( 12 ) on the spring element ( 13 ). 8 . The piece of furniture ( 1 ) according to claim 7 , wherein the at least one stop ( 20 , 30 ) is formed integrally with the at least one spring element ( 13 ). 9 . The piece of furniture ( 1 ) according to claim 1 , wherein at least one of the activators ( 12 ) is manufactured in one piece with a corresponding one of the spring elements.
