Abstract
A shovel having a blade and an elongated handle is provided between the ends thereof with a laterally extending enlargement. A resilient pad and cover are placed over and supported by the enlargement and handle. The supported pad acts as a fulcrum when placed on the user's thigh just above the knee. The loaded blade may then be raised by lowering the free handle end with one hand and when the blade is in a sufficiently raised position, the handle may be grasped with the other hand near the blade for carrying or discharging the load from the blade.
Claims3
A lifting implement comprising an elongated handle having a load-carrying blade on one end,
- a fulcrum device affixed to said handle intermediate the ends thereof in such position to impart a lifting movement to said blade when said device is engaged with the user's thigh and the other end of said handle is moved downwardly, said device being wider than said handle to stabilize said handle against rotation about its axis, said device including a supporting enlargement having a resilient pad on the thigh-engaging portion thereof, said thigh-engaging portion being convexly curved in directions both longitudinally and laterally of said handle, said supporting enlargement having an inner concave surface which fits snugly against said handle surface and a rounded outer surface that extends laterally beyond each side of the thigh-engaging surface of said handle, said enlargement further having predetermined lateral and longitudinal dimensions to distribute the fulcrum force over the area of the user's thigh, said pad being mounted on said rounded outer surface of said enlargement.
A lifting implement comprising an elongated handle and a load blade affixed at one end thereof;
- a fulcrum member being affixed to said handle intermediate the ends thereof;
- said member being positioned longitudinally of said handle to impart a lifting movement to said blade by placing said member on the user's thigh area adjacent the knee and exerting a downward movement of the other handle end;
- the handle lengths on either side of said fulcrum member being proportioned to provide predetermined leverage in lifting and moving said blade;
- said member being laterally wider than said handle to distribute the fulcrum load over the thigh area and stabilize the handle against rotation about the handle axis, the ends of said member being tapered towards said handle to facilitate interference free movement and use of the implement.
