Abstract
Abstract A pivotable wall bracket has a base member adapted to be mounted on a wall, the base member having an upper and lower bearing. A base bracket is formed of a pair of matching bracket members adapted to clamp the bearing members and also to clamp a pair of dowels extending from the pivotal axis of the structure. A holder is formed of a pair of matching holder members which are fixed together to clamp the other end of the dowels. A ridge may be formed on the base to be engageable with one or more notches in the base bracket, to releasably hold the base bracket at determined angular displacements.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
250 words
A pivotable wall bracket comprising a unitary base member having a wall-engaging surface, first and second pairs of projections extending from a surface of said base member opposite said wall-engaging surface, and first and second bearing members extending between the projections of said first and second pairs of projections, respectively, said bearing members having substantially circular cross sections and being substantially axially aligned, the axis thereof parallel to and spaced from said wall-engaging surface, first and second dowels each having an annular groove in its surface adjacent each end thereof, a base bracket comprised of a pair of base bracket members having substantially mirror image shapes and affixed together to define between them first and second bearing holes surrounding said first and second bearing members, respectively, and first and second recesses into which one end of said first and second dowels, respectively, extend in a common plane defined by said axis, said first and second recesses having ridges extending into said grooves to prevent removal of said dowels therefrom, and a holder comprised of a pair of holder members having substantially mirror image shapes and affixed together and defining between them third and fourth recesses into which the other ends of said first and second dowels, respectively, extend, and an end portion adapted to suspend an object, each of said third and fourth recesses having portions extending into the grooves at the respective ends of said dowels extending thereinto, to firmly hold said dowels in said bracket and holder member.
Claim 2
Dependent Claim
250 words
A pivotable wall bracket comprising a unitary base member having a wall-engaging surface, first and second pairs of projections extending from a surface of said base member opposite said wall-engaging surface, and first and second bearing members extending between the projections of said first and second pairs of projections, respectively, said bearing members having substantially circular cross sections and being substantially axially aligned, the axis thereof parallel to and spaced from said wall-engaging surface, first and second dowels each having an annular groove in its surface adjacent each end thereof, a base bracket comprised of a pair of base bracket members having substantially mirror image shapes and affixed together to define between them first and second bearing holes surrounding said first and second bearing members, respectively, and first and second recesses into which one end of said first and second dowels, respectively, extend in a common plane defined by said axis, said first and second recesses having ridges extending into said grooves to prevent removal of said dowels therefrom, and a holder comprised of a pair of holder members having substantially mirror image shapes and affixed together and defining between them third and fourth recesses into which the other ends of said first and second dowels, respectively, extend, and an end portion adapted to suspend an object, each of said third and fourth recesses having portions extending into the grooves at the respective ends of said dowels extending thereinto, to firmly hold said dowels in said bracket and holder member.
Claim 3
Dependent Claim
60 words
The wall bracket of claim 1, wherein one of said base bracket members and one of said holder members have pins projecting therefrom into and through aligned holes In the other of said base bracket member and holder members, respectively, the ends of said pins being staked to firmly hold said base bracket members together and said holder members together.
Claim 4
Dependent Claim
22 words
The wall bracket of claim 1, wherein said base member, base bracket members and holder members are of a die casting material.
Claim 5
Dependent Claim
12 words
The wall bracket of claim 3, wherein said dowels are wood turnings.
Claim 6
Dependent Claim
49 words
The wall bracket of claim 1, wherein said first dowel extends normal to said wall-engaging surface, the axis of said first dowel extending through said first bearing member, and wherein said second dowel is positioned below said first dowel, and extends upwardly from said base bracket to said holder.
Claim 7
Dependent Claim
19 words
The wall bracket of claim 1, wherein said end portion of said holder members is shaped as a hook.
Claim 8
Dependent Claim
72 words
The wall bracket of claim 1, wherein said base bracket members have upper portions defining a first clamp for clamping said base bracket to said first dowel and said first bearing member, and a second clamp for clamping said second dowel and said second bearing member, each of said base bracket members having semi-circular recesses defining portions of said bearing holes, and semi-circular recesses defining portions of said first and second recesses.
Claim 9
Dependent Claim
94 words
The wall bracket of claim 1, wherein said base member further comprises a ridge extending from said opposite surface between the projections of said second pair of projections and parallel to said second bearing member, said second pair of projections being lower than said first pair of projections, said base bracket having at least one notch positioned to engage said ridge at a predetermined angular displacement of said base bracket with respect to said base member, said second bearing hole having an inner diameter greater than the outer diameter of said second bearing member.
Claim 10
Dependent Claim
31 words
The wall bracket of claim 8, wherein said second bearing hole has a larger diameter than said first bearing hole, and said first and second bearings have substantially the same diameter.
Claim 11
Dependent Claim
