摘要:
The present invention relates to an upright shovel to relocate snow or dirt from one location to another. The upright shovel enables a person to shovel snow while standing up straight, without requiring them to repeatedly bend over to lift a pile of snow. The upright shovel features a fulcrum lift system specifically designed for multiplying the mechanical force associated with lifting and unloading snow in a safe and efficient manner. A user pushes down against an actuator shaft to engage a fulcrum bar under a blade. A tip of the blade lifts a load because, attached above the fulcrum bar, is a hinge attached to a support shaft which remains stationary while the actuator shaft moves. Accordingly, when the actuator shaft is raised the tip of the blade lowers to releasing the load.
