Retracting and extending device comprising bidirectional retracting devices

Abstract

A retracting and extending device for sliding doors or drawers includes a housing in which at least one retracting device having a combined acceleration and deceleration device is arranged and in which at least one extending device is arranged. The retracting device and the extending device can be coupled together by means of at least one switchable axial coupling on the basis of the stroke range. A carriage includes such a retracting and extending device. A door guide rail includes a carriage inserted therein. The retracting and extending device has a second retracting device arranged in the aforementioned housing. The combined acceleration and deceleration device is both a part of the first retracting device and a part of the second retracting device. The compact retracting and extending device enables an expanded range of possible applications.
