Abstract
Abstract A plug-assembled multi-shelf sectional display rack constituted of a plurality of horizontal and vertical hollow sections joined together at their ends by corner junctions having vertically and horizontally extending plugs engageable within the hollows of the sections. Each section is provided with a longitudinally extending inwardly facing recess which merges into a hollow longitudinal guide extending axially of the section. Mounted within the recesses and guides of the vertical sections are inwardly extending supports having horizontal surfaces for holding shelves. The supports determine the vertical spacing between the shelves. They include guide sections engageable within the hollow axially extending guides of the sections. Vertical gaps are provided between lateral faces formed on the supports and the walls defining the recesses of the vertical sections to permit insertion of vertical panels.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
172 words
In a plug-assembled sectional rack suitable for display purposes and for use as a selling aid, store decoration, exhibition stand and the like, having hollow sections arranged vertically and horizontally to form, by means of corner junctions having plug connections, frames adapted to receive shelves for exhibiting items and/or vertical panels for multilaterally confining individual display cases within the rack, each of said hollow sections including a longitudinal recess defined by angular walls and a hollow longitudinal guide merging with the recess for accommodating said shelves and said vertical panels, the improvement comprising shelf supports having base portions provided with guide elements for insertion into said hollow longitudinal guides of the hollow sections whereby said shelf supports extend into said recesses, said base portions having upper faces serving as support surfaces for said shelves and having lateral faces for engaging said vertical panels, each said shelf support base portion being shaped such that there are slots between its lateral faces and the walls of said recesses for insertion of the vertical panels.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
48 words
Rack according to claim 1, wherein the shelves are inserted into horizontal hollow sections, characterized in that the base portions of said shelf supports have lateral faces engaging the shelves and the slots between the lateral faces and the walls of said recesses receive and support the shelves.
Claim 4
Dependent Claim
51 words
Rack according to claim 1 or claim 2, wherein said slots have rear ends and said shelf supports have guide edges located adjacent its said guide elements, each said guide edge engaging an adjacent recess wall and having a rectangular face which defines the rear end of one of said slots.
Claim 5
Dependent Claim
33 words
Rack according to claim 3, wherein said hollow longitudinal guide in each of said hollow sections comprises bifurcated guide channels adapted to receive bifurcated arms comprising the guide elements of said shelf supports.
Claim 6
Dependent Claim
60 words
Rack according to claim 3, wherein said hollow longitudinal guide in each of said hollow sections includes at least one stiffening panel connected to the wall of the hollow section so as to form therein a plurality of longitudinal ducts that are parallel to each other and are adapted to receive complemental plug insert portions formed on said corner junctions.
Claim 7
Dependent Claim
20 words
Rack according to claim 5, wherein said plug insert portions of said corner junctions are made of hollow section material.
Claim 8
Dependent Claim
53 words
Rack according to claim 5, wherein said plug insert portions of said corner junctions have inner ends reduced externally by the wall thickness of said hollow sections, and wherein a reinforced core portion of each of said junctions is adapted to receive extensions of said hollow longitudinal guides formed in said hollow sections.
Claim 9
Dependent Claim
53 words
Rack according to claim 3, wherein said shelf supports are made of hollow sections having a base wall and a side wall forming an acute angle to said base wall, and wherein said shelf support guide elements comprise a plurality of spaced profiled sections attached to the leading edge of said side wall.
Claim 10
Dependent Claim
