Description

  The present invention relates to a folding table leg, and more particularly to a table leg that can be folded without turning the table over.

  Various foldable table legs have been proposed in which the legs are erected when the table is used, and can be stored in a small space when the table is not used (Patent Documents 1 and 2).

  In this type of folding table leg, it is important how to lock the leg upright and in the folded position.

  For example, the upper end of the leg is rotatably attached to the bracket on the lower surface of the table, an arc-shaped surface is formed on the upper end of the leg, the lock lever is rotated by its own weight to contact the arc-shaped inclined surface, and a stopper is provided on the opposite side. When the table is turned upside down, the lock lever moves backward with its own weight to disengage from the arcuate inclined surface, unlocks the leg, and folds into the folded position. A table leg is known (Patent Document 3).

  However, the foldable table legs described in Patent Document 3 cannot be folded while the table is in use, and each time the table needs to be turned upside down. Then, the table could not be turned over, and it had to be taken out to a large place, turned over and the legs folded, and the operation was complicated.

  This invention makes it a subject to provide the foldable table leg which enabled it to fold a leg, without turning over a table in view of this problem.

  Therefore, the folding table leg according to the present invention is attached to the lower surface of the table and can be locked to a standing posture standing upright with respect to the table and a folding posture folded up with respect to the table. Folding table legs that can stand up and fold between, the mounting bracket for mounting the legs to the table has a U-shaped main body, and the main body is attached to the lower surface of the table at the upper edge There are mounting flanges, and both side walls of the mounting bracket are opposed to the shaft insertion holes in the width direction, while the legs have flat square mounting portions at the upper end, and are attached to both side walls of the mounting portion. The shaft insertion holes face each other in the width direction, and the rotation shaft is inserted into the shaft insertion hole of the mounting portion and the shaft insertion hole of the mounting bracket, so that the leg can rotate with respect to the mounting bracket. The lower end edge of at least one side wall of the mounting bracket body is an arcuate guide edge centered on the shaft insertion hole, and the guide edge corresponds to a position corresponding to the standing posture of the leg and a folding posture. There is a locking recess at the location, and the locking pin is positioned in the leg so as to be separated from the rotation shaft, and one end of the locking pin can be rotated and swingable in the insertion hole of the mounting portion of the leg The other end of the locking pin is inserted into a long hole extending in the leg longitudinal direction of the leg mounting portion and extends outward, and the locking pin is pulled against the rotating shaft by a biasing spring. The insertion portion of the locking pin is an operation portion for locking and releasing the locking recess with respect to the locking recess.

  One of the features of the present invention is that a mounting bracket and a leg are rotatably connected by a rotating shaft, and a locking pin is provided on the leg so as to be rotatable and swingable, and is pulled and urged toward the rotating shaft. There are two locking recesses on the arcuate guide edge of the bracket so that the locking pins can be selectively locked.

As a result, when the locking pin is released from the locking recess in the standing position against the biasing force of the biasing spring while the table is in use, the locking of the leg can be released and the locking pin is folded while the leg is folded. The leg can be locked in the folded state by swinging along the arcuate guide edge and locking it in the locking recess at the folding position.
As a result, it is possible to fold and stand the legs without turning the table upside down and without taking the table out over a wide area, and the leg can be raised and folded very easily.

  The legs may have a hollow square shape, but it has an angular design and gives the user a hard impression. On the other hand, if the legs are formed into a round pipe shape, for example, a rounded pipe shape, the impression given to the user can be softened. In this case, the width of the portion that receives the rotation axis of the leg is narrowed and the load on the portion is large. Therefore, it is preferable that the upper end portion of the round pipe leg is formed in a plane U shape and an insertion hole for the rotating shaft is formed there.
