发明名称 Universal hand guard for a hacksaw
摘要 A resilient hand guard for protecting the hand of a hacksaw user including a flat shield formed of resilient non-metallic or elastomeric material having a height equal to that of the frame and a width at least as great as a projected frontal width of a user's hand when grasped around the handle. The shield has an elongated notch extending downwardly from an upper margin having a width and length sufficient to be fitted around and receive support from an upper portion of the frame just forwardly of the handle. The shield also has a mounting aperture positioned directly below the notch sized to fit over and receive support from a threaded end of an elongated rear blade tensioning support of the frame. The shield has sufficient resiliency for a side portion thereof to be protectively deflected around the hand upon inadvertent impact against an object during use of the hacksaw.
