FR2722218A1 - Soil collector and wheelbarrow loader - Google Patents

Abstract

A device for collecting earth and loading it into a wheelbarrow is disclosed. A user sits on top of the tub, grabs the scoops while engaging them with his or her arms, and draws the previously broken earth into the back of the tub. The angle of incidence of the scoop on the ground may be varied by simply rotating the scoop relative to the arm, whereby said scoop is alternately used like a ploughshare or placed vertically, and adapts to the various stages of the user's movement as well as to different soils. Once the tub is full, the user crouches behind it, knees apart, then lifts it up and tips the contents into a wheelbarrow. If no wheelbarrow is available, the tub may also be rotated through a quarter of a turn and carried on the user's head. Muscle power is thus used more efficiently and said device requires less work and causes less back strain than conventional shovels.

  An attempt to solve the problem of wheelbarrow loading is brought by a tilting wheelbarrow with two wheels. The bucket of said pin comes to be pressed against the self while tilting around the common axis of the wheels. All that remains is to fill the wheelbarrow by side using a shovel, using as much help as the legs, without having to

  In short, it is a complex comprising: - A tub, receptacle widely open on the front face, of base (1) ample and generally flat, on which comes to pile up a good thirty liters of soil, concave bottom (2), top (4) convex for sitting. and slightly convex sides (3), provided

large handles (6).

  -A pair of pellets, each consisting of a piece (5) enveloping the fingers, in connection with a support (4) for the thumb, a support (3) resting at the base of the arm, a shovel (1), and , a handle (2). Said handle is placed in front of the shovel (1), so that the user

  is fully included in one of the half spaces delimited by the mean plane of the shovel.

  I add, regarding the shovel-arm angles, that the shovel (1) of the right pellet is oriented relative to the right arm. so that the latter being stretched horizontally to the south, palm down, a spring sun in the early afternoon, hits the middle plane of the shovel,

in front.

  Finally, the curvature of each shovel (1) essentially consists of bending

  progressive around axes parallel to the leading edge (8).
