Problems solved by technology

This retraction device has the disadvantage that there is no damping force applied to slow down the closing movement of the rails
However, the springs arranged in the damper housing can only provide low tension and in case of damage cannot be replaced without removing the damper at all

Embodiment Construction

[0035] The pull-out guide device 1 comprises a fixed guide rail 2 which can be fixed on the furniture body; a middle rail 3 and a running rail 4 . The middle rail 3 is arranged between the guide rail 2 and the running rail 4 and the middle rail 3 is shorter than the other two. On the extension line of the intermediate rail 3 , a retraction device 5 fixed on the guide rail 2 is provided, as well as a housing 6 . The retraction device 5 comprises a movable slider 7 connected to a drive 11 . Said slider 7 is pretensioned in the retracted position by means of a spring 9 and is further coupled with a damper 8 to decelerate the closing movement of the running rail 4 before reaching its closed position in order to avoid loud crashing noises.

[0036] like image 3 As shown, the cross-sections of the guide rail 2, the middle rail 3 and the running rail 4 are C or U-shaped. The guide rail 2 has a bottom 20 from which project two leg members 21 which have raceways for the bearing ele...

Abstract

The invention provides a retraction device (5), and particularly the retraction device (5) used for a pull-out guide device (1). The retraction device (5) comprises a housing (6), a guide component (61) used in a linear removable slider (7) and guide rails (63) of a drive device (11) attached to the slider (7) are arranged inside the housing (6), wherein the drive device (11) can be coupled with a starter (10), and between the housing (6) and the slider (7) provides a damper (8) which comprises a casing (80) and a piston rod (81); the retraction device is characterized in that springs (9) are arranged on the periphery of the damper (8), pre-tension is conducted by the slider (7) in the retracted position on the housing (6) with the help of the springs (9). The pull-out guide device (1) containing the retraction device (5) is further provided.

Description

technical field [0001] The invention relates to a retraction device, in particular for a pull-out guide, comprising a housing in which a guide for a linearly movable slider and A guide rail for a drive attached to the slider, wherein the drive can be coupled with a starter, and a damper comprising a damper housing and a piston rod is provided between the housing and the slider, and relates to A pull-out guide device has a fixed guide rail and a running rail movable relative to the guide rail. Background technique [0002] US 6,971,729 B1 discloses a retraction device with a drive that can slide along the housing. The drive can be connected to an actuator that pulls out the guide rail. Thus, the driver is pretensioned in the retracted position by means of a spring which is guided along a pin on the housing. This retraction device has the disadvantage that there is no damping force to be exerted to decelerate the closing movement of the rails. [0003] Further, DE 20 2011 ...
