Abstract
Abstract A construction product for randomly fabricating shelves, divider, etc., comprises a plurality of panels, which have slots that are parallel to and adjacent to edges of such panels, and annular connectors, each of which can be press fitted into the adjacent slots of such panels. The angular relationships among the panels may be selected with great versatility and the angular connectors join selected edges of the panels with respect to each other in order to provide selected anchor points.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
109 words
A shelving product having a plurality of compartments open at the forward and rearward faces comprising a plurality of panel sections and a plurality of rigid annular connectors, each edge of said panel sections having a plurality of elongated slots, each of said slots communicating freely with at least one of said edges and being parallel to at least one of said edges, the width of each of said slots and the thickness of each of said connectors being such that any connector when pressed into any slot is securely retained thereby, said connector pressed into parallel slots of adjacent panels fastening securely said adjacent panels to each other.
Claim 2
Dependent Claim
109 words
A shelving product having a plurality of compartments open at the forward and rearward faces comprising a plurality of panel sections and a plurality of rigid annular connectors, each edge of said panel sections having a plurality of elongated slots, each of said slots communicating freely with at least one of said edges and being parallel to at least one of said edges, the width of each of said slots and the thickness of each of said connectors being such that any connector when pressed into any slot is securely retained thereby, said connector pressed into parallel slots of adjacent panels fastening securely said adjacent panels to each other.
Claim 3
Dependent Claim
18 words
The construction product of claim 1 wherein said panel sections are composed of a high tensile strength material.
Claim 4
Dependent Claim
17 words
The construction product of claim 1 wherein said connectors are composed of a high tensile strength material.
Claim 5
Dependent Claim
54 words
The construction product of claim 1 wherein at least a pair of slots are formed at a corner of each of said panels, one of said slots being parallel to one of the edges of said corner and the other of said slots being parallel to the other of the edges of said corner.
Claim 6
Dependent Claim
43 words
The construction product of claim 1 wherein said slots are formed along a medial edge of said panel and communicate with said edge through a channel, the width of said channel being at least as great as the axial length of said connector.
Claim 7
Dependent Claim
161 words
A shelving product comprising a plurality of panel sections and a plurality of rigid annular connectors, each of said panel sections having a plurality of elongated slots, each of said slots communicating freely with at least one of said edges and being parallel to at least one of said edges, the width of each of said slots and the thickness of each of said annular connectors being such that any annular connector when pressed into any slot is securely retained thereby, each of said annular connectors being press fitted into parallel slots of adjacent panels in order to securely fasten said adjacent panels together, said panels being composed of plywood having a plurality of plies, the grain directions of which are crossed in order to provide both tensile and compressive strength, said annular connectors being composed of a high tensile strength material, said shelving product presenting a plurality of compartments open at the forward and rearward faces of said shelving product.
