ABSTRACT:
Anti-twist signholder support assembly, formed of a male insert, connectable to an overlying signholder, and having an upper horizontal multi-sided anti-twist plate, and a lower lock formation of diametrically arranged resilient catch fingers, and a mating female socket having a platform containing an upper horizontal multi-sided anti-twist recess of shape corresponding to plate and sized for receiving the plate, and a lower slot formation of arrangement and shape corresponding to the lock formation and sized for receiving the lock formation, such that the insert is alternatively coaxially insertable in the socket with the lock formation in the slot formation in more than one interchangeable relative angular rotational position, and such that in any alternative insertion position the recess will engage stationarily the plate for providing an anti-twist connection therebetween in which all external rotational forces about the axes acting on the insert will be transmitted directly by the plate to the recess remote from the lock formation and slot formation.
