Automatic retraction apparatus and pull-out guide

Abstract

Automatic retraction apparatus (100, 200, 300, 400) for a pull-out rail-guided moving furniture part, having - a base body (101, 201, 301, 401), - an energy store which is arranged on the base body (101, 201, 301, 401) and is subjected to tension when the moving furniture part is opened, and the stored energy of which energy store can be used during the closing process as a retraction aid for retraction into the final closed position, - a tensioning mechanism for pretensioning the energy store, which tensioning mechanism is coupled to the moving furniture part up to a predetermined opening position and is automatically decoupled after said specific opening position is exceeded and blocks the tensioned energy store in this position, wherein the tensioning mechanism has two drivers (109, 113, 207, 208, 305, 306, 405, 406) which are coupled to the energy store and synchronously block or activate the tensioning mechanism, and which can be guided separately by respective pull-out rails. The invention also describes a pull-out guide (1) for drawers, pull-out furniture components or the like.

Description

technical field [0001] The invention relates to an automatic retraction device for pulling out rail-guided movable furniture parts according to the preamble of claim 1 and to a pull-out device according to the preamble of claim 13 Guides for drawers, furniture pull-outs, etc. Background technique [0002] Automatic retraction devices and extension guides having such automatic retraction devices are known in various embodiments. [0003] The automatic pull-in device is used to reliably pull movable furniture parts guided by pull-out rails into a closed position. Especially in the case of furniture parts, which are fixed to the furniture body removably via the so-called "full pull-out", the control of the movement of the individual profiles of the pull-out device, that is to say the control of the relative movement of the sliding rails, intermediate rails and guide rails, constitutes a problem, In this way, due to the heavy objects inserted into the movable furniture part, d...

Problems solved by technology

Especially in the case of furniture parts, which are fixed to the furniture body removably via the so-called "full pull-out", the control of the movement of the individual profiles of the pull-out device, that is to say the control of the relative movement of the sliding rails, intermediate rails and guide rails, constitutes a problem, In this way, due to the heavy objects inserted into the movable furniture parts, the pull-out jams due to the defective position of the individual profiles.

[0004] The aforementioned automatic pull-in devices and pull-out guides also have the disadvantage that the actuating forces required for biasing such automatic pull-in devices must be great, and the user of such a movable furniture part therefore only has to use a lot of force. It takes a lot of force to pull out the furniture parts from the furniture body
