家具類の打上移動装置。[Scope of claim for utility model registration] A casing placed at the four corners of the lower part of furniture such as a chest of drawers, and a casing that is attached to each casing via a link mechanism and is provided to move up and down by the operation of this link mechanism. A moving wheel, an operating shaft mounted at the bottom of the furniture in the front-rear direction between the left and right casings, and a link mechanism between the left and right casings that is linked to the rotation of the operating shaft in one direction. a rotary motion transmission mechanism disposed between each of the link mechanisms and the operating shaft so that the movement wheel is moved downward by the operation; The cam is provided with a protrusion for sliding a pin and a protrusion for engaging a locking pawl on the outer periphery, and a locking device installed at the bottom of the furniture, and the locking device is provided on both sides of the cam. An arcuate elongated hole of a predetermined length is bored along the outer periphery of the cam in both side plates hanging from the cam, and the starting and ending ends of the hole are widened on the outside to form a widened part of the housing. and a sliding pin inserted into the elongated hole so as to cross between both side plates of the housing, and a sliding pin that is pivotally connected between the both side plates of the housing so that one end thereof faces the outer circumferential surface of the cam. A piece of furniture comprising a locking pawl, a spring tensioned between the pin and the locking pawl, and a spring urging one end of the locking pawl in a direction away from the outer peripheral surface of the cam. Launch moving device.
