Abstract

Abstract A display device for articles such as audio cassettes and cartridges, the device having at least one wing-like member in the form of a generally rectangular frame for receiving said articles, the frame being pivoted relative to a blocking member so that in one limiting position of the frame the blocking member blocks a region of the frame from which said articles could otherwise be removed, and in another limiting position of the frame the said region is clear of the blocking member so as to allow said removal, the one and the other limiting positions being established by engagement between a pin projecting from the frame and a slot provided in a rotatable plate, locking means being provided for fixing the frame in said one position.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 228 words
A display device comprising a wing-like member in the form of a generally rectangular frame for receiving articles to be displayed; a supporting structure; a rotatable plate carried by said supporting structure; a slot in said rotatable plate; pivot means pivotally mounting said wing-like member about an axis substantially parallel to the plane of the wing-like member, with said axis intersection two oppositely disposed edges of the frame and being parallel to the other two edges of the frame; openings at one of said other edges of the frame through which the said articles can be inserted and removed; a blocking member; a pin extending from one of said oppositely disposed frame edges of said wing-like member at a region of said one edge located between said blocking member and said pivot axis, said pin extending into said slot; said rotatable plate, said slot and said pin constituting means for limiting the pivotable movement of said frame between one limiting position and another limiting position so that in said one limiting position the said openings are blocked by the said one frame edge being in the proximity of the blocking member, whereas in the other limiting position the said one frame edge is clear of the blocking member, thus rendering the articles free for removal; and locking means for fixing the frame in its said one limiting position.
Claim 2
Dependent Claim 228 words
A display device comprising a wing-like member in the form of a generally rectangular frame for receiving articles to be displayed; a supporting structure; a rotatable plate carried by said supporting structure; a slot in said rotatable plate; pivot means pivotally mounting said wing-like member about an axis substantially parallel to the plane of the wing-like member, with said axis intersection two oppositely disposed edges of the frame and being parallel to the other two edges of the frame; openings at one of said other edges of the frame through which the said articles can be inserted and removed; a blocking member; a pin extending from one of said oppositely disposed frame edges of said wing-like member at a region of said one edge located between said blocking member and said pivot axis, said pin extending into said slot; said rotatable plate, said slot and said pin constituting means for limiting the pivotable movement of said frame between one limiting position and another limiting position so that in said one limiting position the said openings are blocked by the said one frame edge being in the proximity of the blocking member, whereas in the other limiting position the said one frame edge is clear of the blocking member, thus rendering the articles free for removal; and locking means for fixing the frame in its said one limiting position.
Claim 3
Dependent Claim 62 words
A display device according to claim 1, wherein a plurality of the wing-like members are provided, each similarly pivotally mounted on the said supporting structure, each having a pin equivalent to said pin, said rotatable plate having one said slot for each pin, the pins, the slots and the rotatable plate constituting means linking all of the wing-like members for joint movement.
