Description

  The present invention relates to a locking device for supporting legs provided on both sides in the longitudinal direction of a folding table.

  In the conventional folding length table, the locking mechanism of the support leg is to lock the support leg by hand, and then lock the tip of the latch provided on the lower surface of the top plate to one end of the support leg. Thus, means for locking the standing state of the support leg has been used.

  However, the conventional locking means for the supporting leg has a problem that the latch has to be locked to the supporting leg for every operation of locking the standing state of the supporting leg, which is troublesome and forgetting to apply the latch. .

  Conventionally, proposals have been made to solve the above problems. For example, in the case where the support leg can be folded on the table top plate, the standing state of the support leg is automatically locked by the standing-up operation of the support leg. Document 1) has been proposed and is a well-known technique.

  However, in the proposal of the “supporting device for the leg support in the leg folding table”, when the support leg is locked, the locking pin is dropped into the locking hole and automatically locks. When releasing, the position of the locking pin of the support leg must be shifted inward by the amount of the locking hole (if it is returned as it is, the locking pin will be fitted into the locking hole again), so The lock device could not be released.

  The present applicant pays attention to the problem that the supporting leg locking device in the conventional folding length table as described above cannot automatically release the locking device, and solves these problems with an easy and simple means. Under the idea that it is not possible to do so, we have developed a support leg lock device that will be locked automatically by raising the support legs of the folding length table and that will be unlocked by raising and lowering the support legs. This leads to the proposal of the “support leg lock device” in the present invention.
