Asymmetric terebrating shovel with lateral displacement slide surface and pivoting level leg

摘要

The asymmetrical head of a shovel incorporates a vertically oriented metatarsal edge extending upwardly from the tip of the head to a recessed offset dorsal edge offset along the entire length of the dorsal edge from the tip of the head. The construction of the head permits it to function both as a pivot and as a lever, as well as facilitating the initial penetration of the head in soil.

主权项

1. A shovel comprising
(a) an elongate handle having a proximate end, a distal end, and a longitudinal axis; and, (b) an asymmetrical head including
(i) an upper end connected to said distal end of said handle and having first and second peripheral distal side edges generally parallel to said longitudinal axis,(ii) a lower end spaced apart from said upper end and said distal end of said handle, said lower end having a ground engaging edge,(iii) a face extending over said upper and lower ends, and said lower end including
(iv) a first convex arcuate peripheral proximate edge terminating at said tip and extending upwardly to said first peripheral distal side edge,(v) a second convex arcuate peripheral dorsal edge
spaced apart from said first arcuate peripheral edge,having an end point spaced apart from and positioned above said tip and below said upper end of said head,extending upwardly from said end point to said second peripheral side edge, andoffset from said end point along the entire length of said dorsal edge,(vi) a substantially straight vertically oriented metatarsal edge extending from said tip upwardly to said end point.and generally parallel to said longitudinal axis,
