Claim 1
Independent Claim
413 words
A frame for a display means, such as a picture, poster, Display panel or the like, comprising a first pair of channelshaped elongate members forming sides which are substantially parallel one to the other and a second pair of elongate channelshaped members forming sides which are substantially parallel one to the other and extend at right angles to the first pair of said elongate members, each of said elongate members having four substantially parallel and spaced apart wall means whereby three parallel grooves are defined, an internal pair of said wall means having downwardly inclined lips at their free edges, and wherein there is means adapted to allow one of said elongate members to be demountable from but remaining secured to the remaining elongate members of said frame, said means comprising an intermediate channel-shaped member having walls with downwardly inclined lips at their free edges, said walls defining a groove with a width corresponding to the width of the middle groove of said first and second pairs of elongate members, said intermediate member being positioned to lie between and parallel to the elongate members of one of said pairs of elongate members and nearer to said one of said elongate members than the other, and resilient means coacting between said intermediate member and said nearer one of said elongate members for urging said nearer one of said elongate members towards said remaining elongate members of said frame, said remaining elongate members of said frame and said intermediate member being secured together by Lshaped clips which are received in said grooves, said demountable one of the elongate members having locating means protruding from the ends thereof for being received in said grooves, said locating means and said resilient means being adapted to allow movement of said one elongate member between a first position in which the locating means is received in the grooves and the frame is complete and a second position in which said one elongate member has been moved away from said intermediate member against the force of said resilient means to allow the locating means to be removed from said grooves, and said urging means permitting said one elongate member to be moved laterally with respect to the plane of the frame when said one elongate member is in said second position to allow access of a display means to one of the outer pair of three grooves and then to the other of the outer pair of the three grooves.
