First Claim
1. A structure, comprising;
- a first element having two spaced apart portions defining a mouth therebetween with a first normal width between said portions;
first and second arms, each of said arms having opposite first and second faces, each of said first faces having a first groove adjacent a first end thereof to receive said portions when said arms are located in said mouth and when said second faces are juxtaposed, said first grooves having bottom surfaces spaced by a distance greater than said first width such that said arms force said portions apart when said second faces are juxtaposed, said first end of each of said arms being bounded by a rolling surface merging with said second face thereof, said rolling surfaces enabling said arms to roll on each other between a locking position in which said second faces are juxtaposed and a release position in which said rolling surfaces are engaged and said arms diverge from said first ends, said arms being inserted into and removed from said mouth in said release position, each of said first faces also having a second groove; and
a second element including formations slideable into said second grooves to maintain said arms in said locking position.

Abstract
A shelf and display structure in which horizontal or sloping members (16, 18, 20) are mounted on a vertical element (12) by locking structures (14.1, 14.2, 14.3). Each locking structure includes a pair of arms (28) which are generally triangular in side elevation. Each arm has three grooves in the outer face thereof. The inner face of each arm is generally flat and merges at one end with a rolling surface. When two arms are placed in co-operating relationship with their rolling surfaces in contact, the arms diverge from one another. In this condition they can be inserted into an elongate mouth of the element (12) and the outer ends of the arms can then be pressed towards one another, the arms rolling on their rolling surfaces until the flat rear faces are juxtaposed. During such rolling motion the element 12 is deformed by the arms so that frictional forces are created which resist movement of the locking structures along the element (12). A horizontal member (16) or sloping members (18, 20) can be mounted on the arms by co-operation between these members and either the horizontal or the sloping grooves. Knobs, hooks or other devices can be mounted on the members (16, 18, 20) to enable articles to be displayed or, where the member is horizontal, it can support shelves.
