Abstract

A self-moving device for movable furniture parts includes a movable part which is movable with respect to a stationary part. The movable part includes first and second connecting portions. A closing mechanism includes a slide base which is movable in response to a force generated by a first elastic member. A locking member connected to the slide base is adapted to engage with the first connecting portion so that the movable part is urged by the first elastic member to be self-closing with respect to the stationary part. An opening mechanism includes a push member urged by a second elastic member to act on the second connecting portion. The movable part may be pushed by an external force to disengage the locking member from the first connecting portion so that the movable part is urged by the second elastic member to be self-opening with respect to the stationary part.

Dependent claims

A self-moving device for movable furniture parts, comprising:

a stationary part;
a movable part longitudinally slidable with respect to the stationary part and comprising a first connecting portion and a second connecting portion;
a closing mechanism mounted on the stationary part, the closing mechanism comprising a guiding member having a first longitudinal portion and a transverse portion extending from one end of the first longitudinal portion;
a slide base connected to the first longitudinal portion and corresponding to the first connecting portion and the second connecting portion;
a first elastic member connected to the slide base;
a locking member movably connected to the slide base, the locking member and the slide base defining a locking space to accommodate the first connecting portion of the movable part;
and a stop portion corresponding to the locking member;
wherein the locking member is moved by the stop portion;
and
an opening mechanism fixed on the stationary part, the opening mechanism comprising a fixed portion;
a push member longitudinally movable in the fixed portion, and a second elastic member connected to the push member, the push member being urged by the second elastic member to engage with the second connecting portion of the movable part.

A self-moving device for movable furniture parts, comprising:

a stationary part;
a movable part longitudinally slidable with respect to the stationary part and comprising a first connecting portion and a second connecting portion;
a closing mechanism comprising a guiding member fixed on the stationary part, the guiding member comprising a first longitudinal portion and a transverse portion, the first longitudinal portion having a first end and a second end opposing to the first end, the transverse portion extending from the first end of the first longitudinal portion;
a slide base connected to the first longitudinal portion;
a first elastic member connected to the slide base;
a locking member movably connected to the slide base, the slide base being urged by the first elastic member to move towards the second end of the first longitudinal portion of the guiding member for the locking member to engage with the first connecting portion of the movable part;
and a stop portion corresponding to the locking member for the locking member to lean on the stop portion to move, and
an opening mechanism comprising a second elastic member disposed on the stationary part and a push member urged by the second elastic member to move;
wherein when the movable part is retracted to a predetermined position with respect to the stationary part, the first connecting portion of the movable part engages with the locking member and the first connecting portion urged by the first elastic member forces the movable part to be self-closing towards the stationary part;
wherein the locking member is movable in response to an external force to lean on the stop portion such that the first connecting portion of the movable part disengages from the locking member, and the movable part is urged by the second elastic member and pushed by the push member to be self-opening.
