Claims (1)

[Claims for Utility Model Registration] Supporting the article on the floor by lifting the article with supporting legs that are installed on the underside of an article having moving wheels and lifting the moving wheels above the floor. A fixing device, which is attached to the four corners of the lower surface of the article, and includes a casing having elongated holes vertically bored in each side plate thereof, and a casing that is freely inserted into the elongated holes of the both side plates of the casing. a supporting leg rod whose upper part is fixed to a pivot shaft mounted thereon and which is vertically movable and rotatably disposed between the both side plates; and a drive shaft installed between the both side plates of the casing. a lever for operating a leg lever, the base of which is pivotally connected to the pivot shaft, and which is disposed between both side plates so as to extend outward from the side ends of the both side plates through above the pivot shaft; and the tip end side of the lever. a spring that biases the pivot shaft upward; and a spring that biases the pivot shaft toward the upper end of the elongated hole, and holds the leg rod in a prone state using the pivot shaft as a fulcrum. and a spring interposed between the leg rod and the lever so that the leg rod is rotated in the direction of the upright state using the pivot shaft as a fulcrum when the lever is pressed down. , After the lever is pushed down, the leg lever is rotated to an upright state, and then the lever is further pushed down and the upper end surface of the leg lever is pressed by the lower surface of the lever, so that the leg lever is moved downward and the leg lever is moved downward. In order to maintain the depressed state of the lever when the article is lifted, the upper part is pivoted to the lower part so as to be able to swing in the direction above the locking part provided on the lever. a lock lever provided with an engaging portion to which the locking portion is engaged; and when the leg lever operating lever is further pushed down from the above state, the locking portion of the lever is disengaged from the engaging portion of the lock lever. A fixing device for a wheeled article, comprising: a spring that biases a lock lever so that the engaging part is swung in a direction in which the engaging part is moved away from the locking part.
