Abstract

An adjustable shelf assembly in which the shelf support is both vertically and angularly adjustable with respect to a vertical channel to which the shelf support connects. The shelf support has projections at its base which engage corresponding notches in the vertical channel to form the connection of the two parts. The uppermost projection is double T-shaped and the notches are also T-shaped. The use of a T-shape on both the shelf support and vertical channel provides a rigid and positive connection.

Dependent claims

A shelf supporting assembly comprising:

a vertical channel having a plurality of T-shaped vertically spaced openings therein, said T-shaped openings each being defined by a horizontally disposed upper slot and a vertically disposed lower slot projecting downwardly from and in communication with said upper slot centrally thereof;
an elongated shelf supporting bracket comprising a body having a horizontally disposed upper edge and a vertically disposed base at one end thereof adapted to be seated against said vertical channel;
a plurality of projections extending rearwardly from said body for selective engagement with the T-shaped openings in said channel;
a first of said projections comprising a horizontally disposed pair of T-shaped elements lying in tandem relation to each other and extending in prolongation of the upper edge of said body, said T-shaped elements each having a top and a centrally disposed leg, the tops of said T-shaped elements each being of a width to be selectely passed through the upper slots of said T-shaped openings when the body of said shelf supporting bracket is vertically disposed, the legs of said T-shaped elements being of a width to be received in the lower slots of said T-shaped openings, the tops of said T-shaped elements being wider than said lower slots, whereby said T-shaped elements may be selectively passed through one of said T-shaped openings and the shelf supporting bracket moved downwardly so as to engage the corresponding leg of the T-shaped element in the lower slot of said opening with the outer ends of the top of the T-shaped element engaging the channel on opposite sides of said lower slot, the shelf supporting bracket extending horizontally outwardly from said channel when the innermost of said T-shaped elements is engaged in said T-shaped opening, and said shelf supporting bracket is inclined downwardly relative to said channel when the other of said T-shaped elements is engaged in said T-shaped opening;
and
at least one lower projection extending rearwardly from the base of said shelf supporting bracket, said lower projection being connected to said vertical base by a connecting member disposed at right angles to said vertical base and engaging in one of the T-shape openings underlying the T-shaped opening in which said first projection is engaged.

a first of said projections comprising a horizontally disposed pair of T-shaped elements lying in tandem relation to each other and extending in prolongation of the upper edge of said body, said T-shaped elements each having a top and a centrally disposed leg, the tops of said T-shaped elements each being of a width to be selectely passed through the upper slots of said T-shaped openings when the body of said shelf supporting bracket is vertically disposed, the legs of said T-shaped elements being of a width to be received in the lower slots of said T-shaped openings, the tops of said T-shaped elements being wider than said lower slots, whereby said T-shaped elements may be selectively passed through one of said T-shaped openings and the shelf supporting bracket moved downwardly so as to engage the corresponding leg of the T-shaped element in the lower slot of said opening with the outer ends of the top of the T-shaped element engaging the channel on opposite sides of said lower slot, the shelf supporting bracket extending horizontally outwardly from said channel when the innermost of said T-shaped elements is engaged in said T-shaped opening, and said shelf supporting bracket is inclined downwardly relative to said channel when the other of said T-shaped elements is engaged in said T-shaped opening;
and
at least one lower projection extending rearwardly from the base of said shelf supporting bracket, said lower projection being connected to said vertical base by a connecting member disposed at right angles to said vertical base and engaging in one of the T-shape openings underlying the T-shaped opening in which said first projection is engaged.
