<p>A combinational transverse strut for a two-in-one arc-shaped or linear advertisement display frame, comprising a base body and a bendable overlay plate, wherein support members are provided at both ends of base body and the overlay plate, respectively, each of both support members comprising a support seat, a support cap, a crankpin, and a magnetic steel; the support cap is provided on its rear portion with an oblique groove; the crankpin is operatively connected between middle portions of the support seat and the support cap, the magnetic steel is fixed between the support seat and the support cap, and the support cap is connected to the support seat; the base body is provided with a pair of pin shaft holes on a side wall approximate to an end point at each of its both ends; the overlay plate is provided with a pair of pin shaft holes on its side wall respectively at each of its both ends the support member is connected to the base body by means of inserting a straight pin shaft into the oblique groove of the support cap and a pair of pin shaft holes on the base body, and the support member is connected to the overlay plate by means of inserting the crankpin into the pair of pin shaft holes of the overlay plate. According to the invention, the two ends of the overlay plate are set up via support members to form an arc shape, so as to achieve applications as a linear member and as an arc-shaped member. Since the adjacent combinational transverse struts are attracted to each other by means of the magnetism of the support members, the structure becomes simpler and connection is convenient.</p> |
