FRAME STORAGE STRUCTURE OF BICYCLE PARKING DEVICE

Disclosed is a frame storage structure, wherein same is arranged in a vertically lifting bicycle parking device, maintains a rigid structure by not bending a frame and a side guard plate in an unloaded state, and performs storage in an inverted state, such that excellent strength and durability are achieved. At the lower layer position of a supporting column (1), a trolley (11), a frame (12), and a support (13) form a rigid right-angled triangle structure in which the trolley and the frame cross at a substantially right angle when viewed from the front and the supporting column forms a hypotenuse. The frame and the support form a rotary slider crank mechanism (10) performing a crank motion by means of a slide pin (131). Therefore, in the unloaded state, the slide pin slides in a long hole (121) in the lengthwise direction, and the frame and the support rotate upwards relative to the trolley to be stored in an inverted state along the supporting column. In addition, in the inverted state, the frame is overlapp
