Load launching shovel

摘要

A hand operated shovel system for moving materials that uses spring enhanced human power to increase force during the flinging part of shoveling. A user adds propulsive force to a shovel having a spring located between the handle and the blade. Motion of the handle and blade rotates the spring to store energy expended during the initial acceleration of lifting, and applies the stored energy back into the material during the deposition step, increasing the ballistic trajectory of the material. If material deposition can be accomplished without flinging, the shovel acts as a substantially rigid body for standard shoveling.

主权项

1. A method of materials movement using spring enhanced human power to increase leverage, the steps comprising:
a) supplying propulsive force to a spring assisted shovel system for said materials movement, said force being selected from the group: impulse and linear; b) modulating said force to said spring assisted shovel system; c) applying torque to a helical torsion spring; d) capturing potential energy within said helical torsion spring; e) varying said force to said spring assisted shovel system; f) releasing said potential energy from said helical torsion spring; g) applying said potential energy to said spring assisted shovel system; and h) applying said potential energy to said materials movement, wherein said application of said potential energy enhances the ballistic trajectory of said materials.
