Claim 4

The invention in accordance with claim 1 including adjustable spacer members for holding adjacent upright supports at a desired spaced relation.

Claim 5

The invention is accordance with claim 1 wherein said means on each said bracket for locking said bracket on said upright support includes a mechanism pivotally connected to the inner portion of the bracket, said mechanism including lug means on the lower portion thereof; and a spring for urgingly holding said lug means in an opening in said upright support when the lugs on the inner end of said bracket are inserted and seated in opeNings on said upright support.

Claim 6

An adjustable display rack assembly comprising a plurality of spaced upright supports; a wire shelf spanning the distance between adjacent upright supports, each said wire shelf including a pair of spaced reinforcing wire members extending from either end thereof, each said wire member having an L-shaped hook on the end thereof, and each said hook provided with a protuberance on the side thereof; a bracket for each end of said wire shelf, each said bracket provided with a pair of spaced loop elements on the upper portion thereof and a pair of spaced loop elements on the lower portion thereof, each said loop elements having a horizontally disposed opening therein; each said bracket being attached to an end of said wire shelf either by slidably fitting the pair of spaced loop elements on the lower portion thereof on the hooks provided on the ends of said wire members whereby the bracket serves as an end wall for said wire shelf or by slidably fitting the pair of spaced loop elements on the upper portion thereof on the hooks provided on the ends of said wire members whereby the top of the bracket is level with the wire shelf; said horizontally disposed openings of said loop elements being shaped to permit said loop elements to be slidably positioned on said hooks past said protuberances when the plane of said bracket is held in a position parallel to the plane of said reinforcing wire members, said protuberances providing for locking said brackets on the ends of said wire shelf when said brackets are rotated on said hooks into an upright position; and means for securing the inner end of each said bracket to an upright support when said bracket is in said upright position.

Claim 7

An adjustable display rack assembly comprising a plurality of spaced upright supports; a wire shelf spanning the distance between adjacent upright supports, each said wire shelf including a pair of spaced reinforcing wire members extending from either end thereof, each said wire member having an L-shaped hook on the end thereof, and each said hook provided with a protuberance on the side thereof; a bracket for each end of said wire shelf, each said bracket provided with a pair of spaced loop elements on the upper portion thereof and a pair of spaced loop elements on the lower portion thereof, each said loop elements having a horizontally disposed opening therein; each said bracket being attached to an end of said wire shelf either by slidably fitting the pair of spaced loop elements on the lower portion thereof on the hooks provided on the ends of said wire members whereby the bracket serves as an end wall for said wire shelf or by slidably fitting the pair of spaced loop elements on the upper portion thereof on the hooks provided on the ends of said wire members whereby the top of the bracket is level with the wire shelf; said horizontally disposed openings of said loop elements being shaped to permit said loop elements to be slidably positioned on said hooks past said protuberances when the plane of said bracket is held in a position parallel to the plane of said reinforcing wire members, said protuberances providing for locking said brackets on the ends of said wire shelf when said brackets are rotated on said hooks into an upright position; and means for securing the inner end of each said bracket to an upright support when said bracket is in said upright position.

Claim 8

an adjustable display rack assembly comprising a plurality of spaced upright supports, the face of each said upright support being provided with vertically spaced openings; a wire shelf spanning the distance between adjacent upright supports; a bracket for each end of said wire shelf each said bracket having a pair of loop elements on the lower portion thereof, a pair of loop elements on the upper portion thereof, a pair of loop elements on the central portion near the inner end thereof, and a pair of clip elements below said latter pair of loop elements; each said bracket attached to an end of said wire shelf either by the pair of loop elements on the lower portion thereof whereby the bracket serves as an end wall for said wire shelf or by the pair of loop elements on the upper portion thereof whereby the top of the bracket is level with the wire shelf; each said bracket provided with three notched lugs on the inner end thereof extending through and seated on the lower edges of selected adjacent vertically spaced openings on said upright support; a locking arm member mounted on the bracket to be slidably movable within the openings of the pair of loop elements on the central portion thereof, and spring means including a length of stiff spring wire having its lower end securely held by the pair of clip elements on said bracket and having its upper end attached to said arm member for urging said arm member to extend through a portion of an opening in the upright support remaining after one of the lugs on the inner end of said bracket has been seated therein to thereby lock the bracket on said upright support.

Claim 9

an adjustable display rack assembly comprising a plurality of spaced upright supports, the face of each said upright support being provided with vertically spaced openings; a wire shelf spanning the distance between adjacent upright supports; a bracket for each end of said wire shelf each said bracket having a pair of loop elements on the lower portion thereof, a pair of loop elements on the upper portion thereof, a pair of loop elements on the central portion near the inner end thereof, and a pair of clip elements below said latter pair of loop elements; each said bracket attached to an end of said wire shelf either by the pair of loop elements on the lower portion thereof whereby the bracket serves as an end wall for said wire shelf or by the pair of loop elements on the upper portion thereof whereby the top of the bracket is level with the wire shelf; each said bracket provided with three notched lugs on the inner end thereof extending through and seated on the lower edges of selected adjacent vertically spaced openings on said upright support; a locking arm member mounted on the bracket to be slidably movable within the openings of the pair of loop elements on the central portion thereof, and spring means including a length of stiff spring wire having its lower end securely held by the pair of clip elements on said bracket and having its upper end attached to said arm member for urging said arm member to extend through a portion of an opening in the upright support remaining after one of the lugs on the inner end of said bracket has been seated therein to thereby lock the bracket on said upright support.
