Abstract
Abstract A shelf bracket structure made of molded plastic material includes channel-shaped support strips which can be secured in vertically extending positions to a wall. Bracing elements extend across the channels and divide the channels into equally spaced elongated recesses in the back of the strips. An opening extends through the front wall of each strip into each of the recesses. Shelf brackets each have on one end an upper hook element received in one of the openings and a lower bracket-aligning projection received in the next lower opening. There is a lateral movement stabilizer for each bracket. In one form of the invention, the stabilizer comprises a pair of lugs on the rear of the strip between which the hook of a bracket slides. In another form of the invention, the stabilizer comprises a tang on the aligning projection, receivable in a narrow slot extending downwardly from each opening. Ends of the strips are formed to overlap each other and end elements cover exposed ends of the strips.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
163 words
A molded, plastic shelf bracket structure comprising: an elongated support strip for attachment in a vertical position to a supporting surface and having a front wall and rearwardly extending portions spacing said front wall from said surface, said strip having a plurality of holes extending through said front wall and spaced uniformly along said strip, a shelf bracket having a first projection in the form of an integral hook-shaped fastening element on the upper portion of one end of the shelf bracket extending through one of the holes, a second projection in the form of an aligning projection on the lower portion of said end of the shelf bracket having a body portion extending through one of the lower holes in said front wall, said bracket and strip having stabilizing means for stabilizing said bracket against unwanted wiggle, said stabilizing means including a pair of lugs at the rear of the front wall and engaging the opposite sides of one of said projections.
Claim 2
Dependent Claim
163 words
A molded, plastic shelf bracket structure comprising: an elongated support strip for attachment in a vertical position to a supporting surface and having a front wall and rearwardly extending portions spacing said front wall from said surface, said strip having a plurality of holes extending through said front wall and spaced uniformly along said strip, a shelf bracket having a first projection in the form of an integral hook-shaped fastening element on the upper portion of one end of the shelf bracket extending through one of the holes, a second projection in the form of an aligning projection on the lower portion of said end of the shelf bracket having a body portion extending through one of the lower holes in said front wall, said bracket and strip having stabilizing means for stabilizing said bracket against unwanted wiggle, said stabilizing means including a pair of lugs at the rear of the front wall and engaging the opposite sides of one of said projections.
Claim 3
Dependent Claim
123 words
The shelf bracket structure of claim 1 in which the recess at one end of the support strip has an open end and the other end of said support strip has a projection thereon of a size to fit said open end so that said projection on the other end of one strip may be inserted into said open end of another of said support strips to provide a resulting support strip of greater length, and in which said one end of said strip and said projeCtion on said other end of the strip have holes therein which are aligned when said projection on said other end of one of said strips is inserted into said open end of another of said strips.
Claim 4
Dependent Claim
161 words
A molded, plastic shelf bracket structure comprising: an elongated channellike, support strip for attachment in a vertical position to a supporting surface and having a front wall and sidewalls spacing said front wall from said surface, said strip having a plurality of holes extending through said front wall and spaced along said strip, a shelf bracket having a first projection in the form of an integral hook-shaped fastening element on the upper portion of one end of one end of the shelf bracket extending through one of the holes and having an upturned hook portion, a second projection in the form of an aligning projection on the lower portion of said end of the shelf bracket having a body portion extending through one of the lower holes in said front wall, said strip having a pair of lugs extending from the sidewalls toward one another and engaging the opposite sides of one of said projections to stabilize said bracket against wiggle.
Claim 5
Dependent Claim
161 words
A molded, plastic shelf bracket structure comprising: an elongated channellike, support strip for attachment in a vertical position to a supporting surface and having a front wall and sidewalls spacing said front wall from said surface, said strip having a plurality of holes extending through said front wall and spaced along said strip, a shelf bracket having a first projection in the form of an integral hook-shaped fastening element on the upper portion of one end of one end of the shelf bracket extending through one of the holes and having an upturned hook portion, a second projection in the form of an aligning projection on the lower portion of said end of the shelf bracket having a body portion extending through one of the lower holes in said front wall, said strip having a pair of lugs extending from the sidewalls toward one another and engaging the opposite sides of one of said projections to stabilize said bracket against wiggle.
Claim 6
Dependent Claim
