Abstract
An ergonomic snow removal implement incorporates a structure which provides an efficient flexure of the implement during the lifting and releasing of the load. In addition, the load carrying portion of the implement is specifically designed to provide a reduced area and consequently, a self limit to the load of each shoveling action.
Claims15
A snow removal implement comprising:
- an elongated handle;
- a blade unit mounted to said handle, said blade unit being semi-flexible and having a generally triangular shape;
- and
- a fulcrum disposed at an intermediate position of said blade unit, wherein a load applied to said blade unit causes said blade unit to flex about said fulcrum and resiliently return to a non-flexed configuration when said load is removed.
1 more element
A snow removal implement comprising:
- an elongated semi-flexible handle defining a longitudinal axis;
- a blade unit comprising a plurality of tines disposed in a fan-shaped, generally triangular configuration with an apex portion being attached to said handle and a base portion mounting a plough member extending transversely to said longitudinal axis;
- a fulcrum disposed at an intermediate location of said blade unit and attached to said handle, wherein when a load is applied to said blade unit, said blade unit flexes about said fulcrum, and when said load is removed, said blade unit springs back to a non-flexed configuration.
