Abstract

Abstract A wall bracket for a one-piece telephone which has a transmitter in a flat base and a receiver at the end of an upright portion extending upward from the base includes a shelf and a roof member which can straddle the telephone. The shelf has a depth such that the center of gravity of the telephone when on the shelf is outward beyond an edge of the shelf so that the telephone if not further supported would rotate about the edge. The roof member extends obliquely toward the shelf and is separated therefrom by a distance such that when the telephone is upright it can pass between the shelf and roof member but thereafter when the telephone rotates about the edge of the shelf the roof member acts as a stop for the receiver end of the upright portion to prevent further rotation and locks the telephone in place.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 220 words
A wall bracket for a one-piece telephone having a flat base with a transmitter in the base and a receiver at the end of an upright portion extending upward from the base, said wall bracket comprising a casing suitable for fastening to a wall a shelf in one end of said casing for supporting a portion of the flat base of the telephone, the shelf having a depth such that when the base of the telephone is on the shelf the center of gravity of the telephone is located outwards beyond the shelf whereby the telephone if further unsupported will rotate about an axis defined by an edge of the shelf, and a roof member in the other end of said casing which extends outwardly and downwardly toward said shelf, the spacing between said shelf and said roof member being such that when said telephone is upright the telephone can freely pass between said shelf and said roof member, but when after the base telephone is on said shelf and the receiver under said roof member and the telephone begins to rotate about said axis away from said casing the receiver end of said upright portion abuts the roof member to prevent further rotation of the telephone whereby the telephone is fixedly supported between said shelf and said roof member.
Claim 2
Dependent Claim 220 words
A wall bracket for a one-piece telephone having a flat base with a transmitter in the base and a receiver at the end of an upright portion extending upward from the base, said wall bracket comprising a casing suitable for fastening to a wall a shelf in one end of said casing for supporting a portion of the flat base of the telephone, the shelf having a depth such that when the base of the telephone is on the shelf the center of gravity of the telephone is located outwards beyond the shelf whereby the telephone if further unsupported will rotate about an axis defined by an edge of the shelf, and a roof member in the other end of said casing which extends outwardly and downwardly toward said shelf, the spacing between said shelf and said roof member being such that when said telephone is upright the telephone can freely pass between said shelf and said roof member, but when after the base telephone is on said shelf and the receiver under said roof member and the telephone begins to rotate about said axis away from said casing the receiver end of said upright portion abuts the roof member to prevent further rotation of the telephone whereby the telephone is fixedly supported between said shelf and said roof member.
Claim 3
Dependent Claim 26 words
The wall bracket of claim 1 wherein said roof member is resiliently biased toward said shelf to accommodate minor deviations in the height of different telephones.
Claim 4
Dependent Claim 31 words
The wall bracket of claim 2 wherein said shelf is defined by a first recess in said casing and said roof member is defined by a second recess in said casing.
