Description

The present invention relates to an automatic moving device for furniture movable members, and more particularly to an apparatus for automatically positioning and moving furniture movable members in a timely manner by integrating a mechanism for automatically opening and closing.

Conventionally, there has been a technology for automatically opening a drawer as an apparatus applied to the drawer. This technology uses the stored elastic energy to release the drawer after positioning and automatically pushes it out from the closed position, but such a device has only one function: simply open. I did not prepare. In Patent Documents 1 to 5, only a slide structure having a function of ejecting and opening is disclosed.

Furthermore, as a device for automatically closing the drawer, a buffering technique relating to a device for automatically pulling back and closing the drawer by an elastic member is disclosed (for example, Patent Document 6).

However, as can be seen from the above-described prior art, the technology for automatically opening and closing the drawer requires an independent mechanism, and thus a device having two different mechanisms is required to automatically open and close the drawer. Although necessary, this could increase assembly costs. Furthermore, it is very inconvenient for the user to combine two different mechanisms and adjust their elasticity respectively. Therefore, there has been a demand for a device that can be used for movable members such as drawers and slide rails and that can be automatically opened and closed.
