Abstract
Abstract A handle for a paint brush or similar tool which facilitates the removal of the paint brush from a display device where the brushes are stacked on a cantilever-type display arm. The paint brush handle includes a generally vertical slot adapted to slidably engage a flat, generally vertically oriented cantilever arm to maintain the brushes in general relative alignment along the arm. The slot in each paint brush handle includes a pair of upwardly converging canted surfaces on the bottom end of the slot to facilitate removal of the brushes from the cantilever arm, for example by a customer desiring to purchase a brush. The paint brush handle may include a hollow interior, or the handle may be solid throughout in which case the canted surfaces terminate in a generally central crown. A generally circular aperture is provided at the upper end of the slot to define a "keyhole" slot so that the brushes also may be displayed on a hanger having a circular cross-section.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
90 words
An improvement in a tool handle having a slot for supporting the tool on an elongated cantilever hanger arm of a cross-sectional shape generally complementary to the shape of said slot, the improvement comprising: a crown defined by two flat, inwardly and upwardly directed surfaces formed at the bottom of the slot to prevent engagement of the edges of the slot at the bottom thereof with the cantilever hanger arm to prevent binding when the tool is canted with respect to the hanger arm during mounting thereon and removal therefrom.
Claim 2
Dependent Claim
90 words
An improvement in a tool handle having a slot for supporting the tool on an elongated cantilever hanger arm of a cross-sectional shape generally complementary to the shape of said slot, the improvement comprising: a crown defined by two flat, inwardly and upwardly directed surfaces formed at the bottom of the slot to prevent engagement of the edges of the slot at the bottom thereof with the cantilever hanger arm to prevent binding when the tool is canted with respect to the hanger arm during mounting thereon and removal therefrom.
Claim 3
Dependent Claim
97 words
A handle for a tool or the like for supporting the tool on a generally vertically flat, horizontally extending cantilever arm, comprising: a vertical slot in the tool handle adapted to slidably engage the cantilever arm; and a pair of flat inwardly and upwardly converging canted surfaces formed at the bottom of the slot to prevent engagement of the bottom edges of the slot with the arm as the tool is canted relative to the cantilever arm during mounting and removal to prevent binding and to facilitate relative sliding movement between the handle and the cantilever arm.
Claim 4
Dependent Claim
97 words
A handle for a tool or the like for supporting the tool on a generally vertically flat, horizontally extending cantilever arm, comprising: a vertical slot in the tool handle adapted to slidably engage the cantilever arm; and a pair of flat inwardly and upwardly converging canted surfaces formed at the bottom of the slot to prevent engagement of the bottom edges of the slot with the arm as the tool is canted relative to the cantilever arm during mounting and removal to prevent binding and to facilitate relative sliding movement between the handle and the cantilever arm.
Claim 5
Dependent Claim
28 words
The tool handle of claim 2 wherein the tool handle is solid throughout and the canted surfaces terminate at a crown at the interior center of said slot.
Claim 6
Dependent Claim
45 words
The tool handle of claim 2 wherein said handle is generally hollow having walls bounding said slot, said walls at the bottom of said slot having edges which are bevelled so as to be canted inwardly and upwardly toward the hollow interior of the handle.
Claim 7
Dependent Claim
55 words
The tool handle of claim 2 including a generally circular aperture at the upper end of said vertical slot and in communication therewith to define a generally "keyhole" shaped slot to permit the handle to slidably engage and be supported by both of said vertically flat cantilever arms as well as a circular cross-sectional arm.
Claim 8
Dependent Claim
128 words
A tool handle and cantilever hanging support comprising, in combination: a cantilever support arm extending outwardly from a suitable supporting surface, said support arm comprising a generally flat, vertically oriented arm member; a vertical slot in the tool handle adapted to slidably engage the cantilever support arm to maintain vertical alignment of the tool handles and relative alignment between a plurality of tool handles; and a pair of flat inwardly and upwardly canted converging surfaces formed at the bottom of the slot to prevent binding by preventing engagement of the edges of the slot at the bottom thereof with the cantilever arm as the tool is canted relative to the cantilever arm during mounting or removal to facilitate relative sliding movement between the handle and the cantilever arm.
Claim 9
Dependent Claim
128 words
A tool handle and cantilever hanging support comprising, in combination: a cantilever support arm extending outwardly from a suitable supporting surface, said support arm comprising a generally flat, vertically oriented arm member; a vertical slot in the tool handle adapted to slidably engage the cantilever support arm to maintain vertical alignment of the tool handles and relative alignment between a plurality of tool handles; and a pair of flat inwardly and upwardly canted converging surfaces formed at the bottom of the slot to prevent binding by preventing engagement of the edges of the slot at the bottom thereof with the cantilever arm as the tool is canted relative to the cantilever arm during mounting or removal to facilitate relative sliding movement between the handle and the cantilever arm.
Claim 10
Dependent Claim
28 words
The tool handle of claim 6 wherein the tool handle is solid throughout and the canted surfaces terminate at a crown at the interior center of the slot.
Claim 11
Dependent Claim
45 words
The tool handle of claim 6 wherein said handle is generally hollow having walls bounding said slot, said walls at the bottom of said slot having edges which are bevelled so as to be canted inwardly and upwardly toward the hollow interior of the handle.
Claim 12
Dependent Claim
54 words
The tool handle of claim 6 including a generally circular aperture at the upper end of said vertical slot and in communication therewith to define a generally keyhole shaped slot to permit the handle to slidably engage and be supported by both said vertically flat cantilever arms as well as a circular cross-sectional arm.
