Definitions

• the present invention relates to both the manual loading of a wheelbarrow and the transport carried.
• the present invention consists of:
• the bottom (2) is concave in order to follow the shape of the belly and to approach the body, the center of qravity of the tub.
• the user tilts the bucket a quarter turn backwards, so that in this position, the sides (3) and the top (4) act as side walls, then he loads the bucket on the head.
• the area (5) in the center of the bottom (2) is precisely hollow in order to match the shape of the skull.
• the tub can be likened to a basin, making it possible to contain at least all of the soil previously harvested.
• the distance between the handles is limited to allow a squatting man, knees loosely apart, to grasp the poiq Amsterdam of the bucket, pressing the back of the arms on the inside of the legs, near the qenoux.
• the optimal way of lifting the bucket also provides indications concerning the position of the handles in relation to the center of life.
• the bucket For a use of filling a bucket, the bucket must be raised from the ground to the belly without rotation. To achieve this translation as well as possible, the handles should be placed above and in front of the center of gravity (above for reasons of stability, in front to prevent the bucket from losing its contents and also because catching the handles by below creates a couple tending to tilt the bucket forward).
• the base is a plywood board embedded in the resin.
• the geometry of the pellets comes from a synthesis of various functions.
• the shovel of a pellet must first penetrate the ground, which requires a high incidence.
• the shovel pushes and accelerates the earth towards the bucket, ze which this time requires the straightening of the shovel,
• the direction of the arm is different depending on whether the shovel is far or close to the bucket, which Unfortunately, this only worsens our problem.
• the arm support considerably limits the freedom of the shovel. To be precise, there is only one; the rotation of the poiqnet around the arm. But it is enough.
• the part of the edge of the shovel intended to be applied to the ground consists of two leading edges (7) and (8), arranged on either side of the angle of attack (6).
• the shovel approaches the vertical (ca which allows one of the two angles (shovel, arm) to be fixed around 140
• the edge (8) which is applied to the ground fiq. 1, left pellet
• the shovel is oblique, thus allowing to penetrate the self under an incidence (which makes it possible to fix the other angle around 50o (fiq. 4).
• the armrest indirectly opposes the force that the earth exerts on the shovel. So that it fulfills this function whatever the leading edge presented on the ground, the arm support is strongly curved and opposite to the leading edge (6).
• the shape of this support located near the elbow does not affect the articulation of the arm. More precisely, the part which is applied to the back of the arm is more distant from the poiq Avenue than the part which is applied to the inside of the arm (see for example FIG. 3).
• the handle (2) is arranged so that when the user presents the point of attack (6) on the ground, his hand rests on the handle, in a middle position. More precisely, it is opposite the leading edge (7), and its axis is intersecting at the leading edge (8).
• the enveloping piece (5) connects the poiq Avenue to the shovel which it extends continuously. More precisely, this part (5) and the shovel (1) essentially constitute one and the same continuous surface, and even almost differentiable on the curved line of their connection. In order to treat the continuity of the part (5) with the shovel, it will be possible, in a luxury version, to provide the shovel with a second curvature of line, by stamping. To protect it, this piece (5) must wrap the hand, while freeing up maximum space for the soil, inside the shovel. As a result, except in the vicinity of its free edge, the curvature of the part (5) is negative (for a given point, the two main centers of curvature being arranged on either side of the surface).
• the part (5) has an overflow (4).
• the largest length of the shovel (1) is 37 cm.
• the rest of the pellet is made of plastic.
• Figure 1 is a general presentation of the present invention, the earth picks up.
• Figures 2,3,4 are three two by two orthogonal views of the right pellet. More specifically, Figure 2 is a side view, Figure 3 an interior front view, Figure 4 a bottom view.
• Figure 5 is a top view
• Figure 6 is a front view in section along A-A (the edge of the base is not shown)
• Figure 7 a side view.
• -A bucket container widely open on the front face, base (1) wide and generally flat, on which is piled up a good thirty liters of soil, bottom (2) concave, top (4) convex allowing to sit down, and flanks (3) slightly convex, fitted with 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.
• each shovel (1) is essentially constituted by a progressive bending around axes parallel to the leading edge (8).
