Abstract

An assembly has a handle, a brush holder, and a support that connect and disconnect to each other using a locking mechanism. The handle reversibly connects and disconnects from the brush holder. The locking mechanism includes a connecting member on the brush holder that attaches to the handle by interaction of a locking flange on the connecting member with a pair of teeth inside of the handle. Insertion of the support within the brush holder extends a post on the support through the connecting member to interact with the handle and enable disconnection of the handle from the brush holder when the support is fully engaged by the brush holder. The locking mechanism prevents the handle from releasing from the brush holder before the brush holder is completely seated on the support.

First claim

The invention is claimed as follows:

1. A brush holder assembly comprising:
a support comprising a post having a length;
a brush holder comprising (i) a connecting member extending outward from a surface of the brush holder and (ii) a bore that extends from an opening in the connecting member to an opening on an opposite side of the surface relative to the connecting member, the bore having a length less than the length of the post; and
a handle comprising (i) a shell configured to receive the connecting member and (ii) a core configured to receive the post, the core comprises teeth that extend downward from opposite sides of the core, one of the teeth comprises a groove, the connecting member comprises a boss, and the groove is configured to receive the boss.

2. The brush holder assembly of claim 1 wherein the brush holder comprises a brush box configured to receive a brush and further comprises a back plate fixed to the brush box, and wherein the back plate comprises the surface from which the connecting member extends.

3. The brush holder assembly of claim 2 wherein the support comprises a body and a flange that extends from opposite sides of the body, and wherein the back plate is configured to receive the support.

4. The brush holder assembly of claim 1 wherein the shell comprises a cavity in which the core is moveably positioned.

5. The brush holder assembly of claim 4 wherein the shell comprises additional teeth, the additional teeth extend inward into the cavity in a horizontal direction.

6. The brush holder assembly of claim 1 wherein the post has a radius, the core comprises a recess having a radius, and the radius of the recess is substantially the same as the radius of the post.

7. The brush holder assembly of claim 1 wherein the connecting member comprises a locking flange that extends outward in a horizontal direction from opposite sides of the connecting member.

8. The brush holder assembly of claim 1 wherein the handle comprises a spring that biases the core downward.

9. The brush holder assembly of claim 1 wherein the post comprises a rocker arm that rotates relative to the post.
