Abstract:
1. A resilient stop assembly for an impact tool, comprising: first and second resiliently deformable parts, and a substantially rigid part situated, at least in use, between the resiliently deformable parts, each of the first and second resiliently deformable parts and the substantially rigid part comprising opposing first and second impact surfaces, at least one peripheral surface joining the first and second impact surfaces, and an aperture extending entirely therethrough between exit openings in the impact surfaces, wherein the first impact surface of the second resiliently deformable part is separated from the second impact surface of the first resiliently deformable part by contact of the first and second impact surfaces of the second and first resiliently deformable parts, respectively, with the substantially rigid part, wherein the second impact surface of the substantially rigid part is in contact with . the first impact surface of the second resiliently deformable part, and wherein the second impact surface of the substantially rigid part has a greater area than the first impact surface of the first resiliently deformable part, wherein at least a portion of the peripheral surfaces of at least one of the first and second resiliently deformable parts flares outwardly in a direction from the first impact surface to the second impact surface thereof wherein at least one of the first and second impact surfaces of the second resiliently deformable part is greater in area than at least one of the filet and second impact surfaces of the first resiliently deformable part.
