Paint Brush with Reinforced Ferrule Construction

Abstract

A paint brush includes a handle having an attachment end and a grip end. The attachment end has an overall width larger than the grip end. A plurality of bristles is coupled to the attachment end of the handle by a resin. An extension extends from the attachment end of the handle into the resin and toward the plurality of bristles. The extension has a substantially planar surface that faces the plurality of bristles. A groove is formed within the extension and has an opening on the planar surface facing the plurality of bristles. The opening is sized and shaped to allow resin to at least partially fill the groove so as to further reduce independent movement of the handle with respect to the plurality of bristles.

What is claimed is: 
     
         1 . A brush for transferring a coating to a surface, comprising:
 a) a plurality of bristles;   b) a resin disposed about and joining an end of each of the plurality of bristles together; and   c) an end of a handle attached to the resin, the handle extending away from the plurality of bristles;   d) an extension extending from the end of the handle into the resin and toward the plurality of bristles with a substantially planar surface facing the plurality of bristles; and   e) a groove formed within the extension and having an opening on the planar surface facing the plurality of bristles, the opening being sized and shaped to allow resin to at least partially fill the groove to further reduce independent movement of the handle with respect to the plurality of bristles.   
     
     
         2 . A brush in accordance with  claim 1 , wherein the groove extends across a longitudinal length of the extension. 
     
     
         3 . A brush in accordance with  claim 1 , wherein the groove includes a pair of substantially planar sides that extend into the extension from the opening on the planar surface and away from the plurality of bristles. 
     
     
         4 . A brush in accordance with  claim 1 , wherein the extension has a smaller cross section than a cross section of the end of the handle such that the resin surrounds the extension. 
     
     
         5 . A brush in accordance with  claim 1 , wherein the resin forms a recess that is sized and shaped to receive the extension. 
     
     
         6 . A brush in accordance with  claim 5 , wherein the recess formed in the resin corresponds in size and shape to the size and shape of the extension and the groove. 
     
     
         7 . A brush in accordance with  claim 5 , wherein the extension, recess, and groove together form a mechanical lock between the end of the handle and the resin to reduce independent movement of the handle with respect to the plurality of bristles. 
     
     
         8 . A brush, comprising:
 a) a handle having an attachment end and a grip end, the attachment end having an overall width larger than the grip end;   b) a plurality of bristles coupled to the attachment end of the handle by a resin;   c) an extension extending from the attachment end of the handle into the resin and toward the plurality of bristles with a substantially planar surface of the extension facing the plurality of bristles; and   e) a groove formed within the extension and having an opening on the planar surface facing the plurality of bristles, the opening being sized and shaped to allow resin to at least partially fill the groove to further reduce independent movement of the handle with respect to the plurality of bristles.   
     
     
         9 . A brush in accordance with  claim 8 , wherein the groove extends across a longitudinal length of the extension. 
     
     
         10 . A brush in accordance with  claim 8 , wherein the groove includes a pair of substantially planar sides that extend into the extension from the opening on the planar surface and toward the grip end of the handle. 
     
     
         11 . A brush in accordance with  claim 8 , wherein the extension has a smaller cross section than a cross section of the attachment end of the handle such that the resin surrounds the extension. 
     
     
         12 . A brush in accordance with  claim 8 , wherein the resin forms a recess that is sized and shaped to receive the extension. 
     
     
         13 . A brush in accordance with  claim 12 , wherein the recess formed in the resin corresponds in size and shape to the size and shape of the extension and the groove. 
     
     
         14 . A brush in accordance with  claim 12 , wherein the extension, recess, and groove together form a mechanical lock between the attachment end of the handle and the resin to reduce independent movement of the handle with respect to the plurality of bristles. 
     
     
         15 . A paint brush, comprising:
 a) a handle;   b) a plurality of bristles coupled to an end of the handle by a resin;   c) an extension extending from the handle into the resin and toward the plurality of bristles with a substantially planar surface facing the plurality of bristles; and   d) a groove formed within the surface of the extension and having a pair of planar sides that extends into the extension away from the plurality of bristles.   
     
     
         16 . A paint brush in accordance with  claim 15 , wherein the groove is sized and shaped to allow resin to at least partially fill the groove to further reduce independent movement of the handle with respect to the plurality of bristles. 
     
     
         17 . A paint brush in accordance with  claim 15 , wherein the groove extends across a longitudinal length of the extension. 
     
     
         18 . A paint brush in accordance with  claim 15 , wherein the extension has a smaller cross section than a cross section of the attachment end of the handle such that the resin surrounds the extension. 
     
     
         19 . A paint brush in accordance with  claim 15 , wherein the resin forms a recess that is sized and shaped to receive the extension and the groove. 
     
     
         20 . A paint brush in accordance with  claim 15 , wherein the extension, groove, and resin together form a mechanical lock between the attachment end of the handle and the resin to reduce independent movement of the handle with respect to the plurality of bristles.
