发明名称 Curling stone washer and handle assembly
摘要 A curling stone handle of one piece construction contoured to conform with the contour of the face of existing curling stones combined with a ribbed washer of plastic oriented interiorly of the cupped area only in the curling stone and a bolt extending through the curling stone and securing the handle and washer in place with the bolt including a head that will fit any curling stone recess and provided with a polygonal depression for receiving a wrench to facilitate assembly and disassembly of the handle, washer and bolt with respect to the curling stone. The washer is formed having a central bore and a plurality of radially extending ribs extending from the bore to the periphery of the washer. The ribs are provided with a flat side surface and a convex opposite curved surface, both surfaces extending substantially perpendicular from one flat side of the washer. The washer is placed between the curling stone and handle and having the ribs facing downward in contact with the curling stone. When the bolt is tightened to secure the handle to the curling stone the ribs will fold and be compressed to prevent relative movement between the handle and curling stone.
