Then, the screw 32 of the cover 30 is fastened to the lower end of the sheet frame 1 on which the mattress (not shown) is seated.

Accordingly, the bed leg 100 is fixedly mounted to the seat frame 1 to space the mattress from the floor.

However, such a conventional bed leg has a disadvantage in that the shock is absorbed only in the mattress when the shock is applied to the bed lacks the shock absorption.

In addition, when a shock is applied to the bed, the shock is directly transmitted to the legs of the bed, and thus there is a problem in that the service life is reduced due to the broken or repeated shock.

In addition, the fixing of the cover coupled to the upper end of the body is uncertain, there was also a problem that the cover is often moved up and down from the body.

The present invention is devised to solve the problems described above, and provides a bed leg that can absorb the shock applied to the bed from the mattress and the leg double by inserting the shock-absorbing elastic member in the bed leg. I want to do that.

In addition, the object of the present invention is to provide a bed leg capable of absorbing the shock transmitted directly to the bed leg to prevent the breakage of the leg and extending the life.

In addition, it is another object to provide a bed leg that can prevent the cover from being separated from the bed leg by improving the cover structure and the body structure to prevent the up and down flow of the cover mounted on the bed leg.
