Abstract
Abstract Especially suitable for use in confined areas such as the inside of a panel truck end support units fabricated from plated steel wire each includes vertical posts or standards drilled at spaced intervals with the holes in front post being substantially in alignment horizontally with the holes in the back post. Shelves fabricated from plated steel wire are easily located and removably attached to both of the end panels in the holes of the post thereof from one side of the assembly which may be the aisle of a panel truck. Each shelf is held in place by rearward projecting and horizontally disposed pins on each end of the shelf and each pin being inserted in their respective aligned hole in the back post of the assembly and rearwardly depending ends on each end of the front of a respective shelf which likewise is positioned in the corresponding hole in each of the front post. Shelves are positioned and placed for use by aligning the respective pins at the front and the back of the shelf with the respective openings in the vertical posts and then pushing the shelf rearwardly into position. The shelf is removed by pulling same forward. Optionally a spring member made from a piece of bent and looped wire is pressed out of the way for insertion of the shelf and permitted to spring into position behind the post once the shelf is seated in the respective holes thereby preventing accidental dislodgement of the shelf. The spring member is displaced manually by pressure from one finger while holding on to another part of the shelf.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
138 words
In an adjustable shelf assembly: a. vertical support members supported to extend upwardly and having spaced openings arranged vertically therein, there being front and rear vertical support members at opposite ends of said structure, b. a rigid quadrilateral shelf structure having front and rear insertion members at opposite ends thereof insertable in respective front and rear openings in said front and rear support means, said openings in said supports facing outwardly in the same direction so that the shelf is inserted from the front only by engaging both said front and rear insertion members in the respective openings at the same level and pushing said insertion members into said openings whereby said shelf may be installed or removed from the front when the rear is closed as for example on one side of the inside of a truck.
Claim 2
Dependent Claim
138 words
In an adjustable shelf assembly: a. vertical support members supported to extend upwardly and having spaced openings arranged vertically therein, there being front and rear vertical support members at opposite ends of said structure, b. a rigid quadrilateral shelf structure having front and rear insertion members at opposite ends thereof insertable in respective front and rear openings in said front and rear support means, said openings in said supports facing outwardly in the same direction so that the shelf is inserted from the front only by engaging both said front and rear insertion members in the respective openings at the same level and pushing said insertion members into said openings whereby said shelf may be installed or removed from the front when the rear is closed as for example on one side of the inside of a truck.
Claim 3
Dependent Claim
33 words
The device claimed in claim 1, wherein: said insertion members are located adjacent each of the four corners of said shelf and all of said insertion members project in the same direction rearwardly.
Claim 4
Dependent Claim
34 words
The arrangement claimed in claim 1, wherein: there are four sets of spaced, vertical openings on said support members and each of said support members is located at a respective corner of said assembly.
Claim 5
Dependent Claim
78 words
The device in claim 3: said rigid shelf structure being of quadralateral form and having a projecting insertion member adjacent each corner thereof and all of said projecting insertion members extending in the same direction towards the direction of insertion of said shelf into said openings whereby each of said insertion members is aligned in a respective opening in said supports and said shelf is inserted on said supports by pushing same in one direction into said openings.
Claim 6
Dependent Claim
35 words
The device claimed in claim 3: said openings being vertically spaced and facing all in the same direction and said insertion members being substantially horizontally arranged on said shelf structure for insertion in said openings.
Claim 7
Dependent Claim

The device claimed in claim 1: a latching member on said shelf manually movable to permit the insertion of the insertion members in the supports and being movable after the shelf is in place to be on the opposite side of said support from the opening in which said insertion member is inserted.
Claim 8
Dependent Claim
107 words
The shelf apparatus claimed in claim 1, wherein: said support means includes floor posts arranged in spaced relation both longitudinally and transversely to provide four corners of the structure, each of said posts having spaced openings therein and said openings corresponding to one another and all of said posts to represent a shelf location at a particular horizontal elevation, said shelf structure being a rigid assembly of longitudinal and transverse members including a longitudinal front member and a longitudinal back member and said insertion members being extensions of said longitudinal members and extending therefrom substantially transversely on the ends of and adjacent the corners of each shelf.
Claim 9
Dependent Claim
35 words
The device in claim 1: said vertical support means including a plurality of vertical members in spaced relation defining a three dimensional structure, said shelf structure having horizontal projecting insertion members near opposite ends thereof.
Claim 10
Dependent Claim
