  • Manual shovel accessory and shovel apparatus with rear end fulcrum and front and rear upright handles
    Patent number: 9204587
    Abstract: A shovel accessory features a main longitudinal beam having opposing front and rear ends for supporting the handle shaft of a shovel thereon, an undercarriage depending downward from the beam to define a fulcrum point when in contact with the ground, and front and rear handle arrangements residing above the main beam at locations respectively nearer to the opposing ends thereof. The front and rear handles provide gripping points for respective hands of the user for pivoting of the main beam and shovel about the fulcrum in a direction lifting the shovel head under rearward pulling of the front handle arrangement. The dual elevated handle arrangement is particularly well suited for a rearward throwing action of material from the shovel head compared to prior fulcrum/lever shovel solutions.
