Abstract:
1. A base structure of a retainer for a shelf, an arm-like hanger or a hook display fitting for displaying commodities on a wall surface, comprising: a wall member which is vertically long and formed to have a columnar groove formed in a longitudinal direction, and locking sections symmetrically formed at prescribed intervals in the groove, having inclined wall surfaces to open or close bottom ends of pivotally movable locking pieces; a sliding member which has a slide block for sliding inserted into the groove of the wall member and is provided with the pivotally movable locking pieces which have top ends and bottom end faces, wherein the movable locking pieces have a male arc sliding surface on sides of said top ends, mutually engaged with and slide on a female arc sliding surface formed on a slide block side opposite to the male arc sliding surface to perform an opening or closing operation of the locking pieces in the slide block; and a support arm which is protruded from the sliding member, wherein the insertion of the sliding member into the groove of the wall member causes to project the movable locking pieces so to be locked by the locking section in the groove, thereby preventing the slide block from lowering.
