Problems solved by technology

However, this embodiment has the disadvantage that additional frictional forces act on the spring due to the deflection and that additional installation space is required transversely to the structural longitudinal direction of the retraction robot
In addition, the retracting mechanism must be relatively expensive to produce

Embodiment Construction

[0018] one in figure 1 The retraction device 1 shown in the lower region of , comprises a housing 2 which can be mounted on a furniture cabinet or on a fixed rail of the extension guide. A curve guide 20 with a curved end section 21 is formed in the housing 2 . A driver 3 is guided in the curve guide 20 and has two pins 4 which engage in the curve guide 20 . A recess 5 is formed on the carrier 3 for a trigger which can be inserted into the recess 5 in order to couple the carrier 3 to a movable furniture part in the region of the curve guide 20 .

[0019] The driver 3 is pretensioned to the left by a compression spring 6 and a tension spring 7 . The compression spring 6 is supported on one side of the housing 2 and is coupled on the opposite side to a connecting piece 9 which in turn is connected to the tension spring 7 . The tension spring 7 is connected to the connecting part 8 with the driver 3 on the side opposite the connecting part 9 .

Abstract

The invention relates to a retracting device, in particular for drawers, comprising a housing (2) on which a driver (3) is guided, wherein said driver (3) is movable from a drawing-in to a parking position against a spring force and is coupled to a closable furniture part for holding it in the closed position thereof. According to said invention, the driver (3) is prestressed in the drawing-in position by means of at least two springs (6, 7, 16) which are coupled therebetween by means of a connecting part (9, 9', 90). The use of individual springs (6, 7, 16) makes it possible to obtain an important spring path for a compact structure.

Description

technical field [0001] The invention relates to a retracting device, in particular for a drawer, comprising a housing on which a drive element is guided, wherein the drive element can be moved against a spring force from a retracted position into a rest position, and the drive element It can be coupled with a closeable furniture part in order to keep the furniture part in the closed position. Background technique [0002] A closing device for drawers is known from EP 391 221, in which an automatic retraction device is provided in order to hold the drawer in the closed position or bring it there by spring force. For this purpose, a linearly movable carrier is provided in a guide, which is pulled into an end position by a pretensioned spring, and which is tipped over and snapped into the curved part of the guide rail by means of a dowel remain in an opposite stop position. The spring is fastened with one end to the movable driver and with the other end to the housing or the ...
