<p>A shovel apparatus for digging holes has an H-shaped frame (10) providing at one end (12), a handle (14) integrally joined to the frame (10), and at the other end (16), a blade mounting support (18). A pair of spaced apart shovel blades (20) are pivotally engaged with the blade mounting support (18) for drawing the blades (20) from essentially parallel rest positions, toward each other, to form a modified cone-shaped enclosure. A draw arm assembly (30) is engaged for sliding within a pair of opposing slots (11) in the H-shaped frame (10). The draw arm assembly (30) is engaged with the shovel blades (20) through a pair of links (60) to move the shovel blades (20) toward each other when the draw arm assembly (30) is pulled toward the handle (10).</p> |
