Abstract: The self-raising spade is designed to enable material to be moved from a low level and raised to a working height, without requiring the user to bend or stoop. The action does not require the user to take the weight of the load whilst in a bent posture, therefore reducing the risk of physical injury. The essential feature of this invention is the triangular support leg upon which the load rises to a selected height, this being brought about by the natural backwards motion of the user, the leg returning automatically towards the shaft on discharge of the spade towards the side.

Abstract: Improvements to a device for reducing the effort of lifting soil with a spade or the like, the device comprising an arm (3) articulated at one end on a collar (16) wherein rotates the handle of the tool (1) and having at its other end a grip (2) held by the fore hand, so that the lifting of the spade ladden with soil may be effected only with a flexure of the legs without bending the trunk. The improvements comprise: 1) an elastic device (5) applying the arm (3) on the top part of the handle of the tool (1) when the grip (2) of the arm is released; 2) a telescopic device of the arm (3) enabling to adjust its length in relation to the size of the person; 3) an elastic device (18, 21) effecting the return of the arm at the front of the tool, which is the initial position, when the grip of the arm is released and the spade has been turned over to any side.

Abstract: The present invention relates to an arrangement for a hand tool (1), for example a spade, a pitchfork or a shovel. The tool comprises a shaft (2), which at one of its ends is attached to a tool component (3) and at its other end is executed with a handle (4). The invention is characterized in that the hand tool component (3) is attached to the shaft (2) in such a way that its principal direction of longitudinal extension (5) forms an angle (v1) of the order of 140 DEG -150 DEG with the shaft (2) at the attachment. The length of the shaft (2) is of the order of 1-1.5 m, and is executed at a point approximately half way along its length with a bend (6), so that the part (2a) of the shaft (2) between the handle (4) and the bend (6) forms an angle (v2) with the part (2b) of the shaft (2) situated between the bend (6) and the tool attachment. The last-mentioned angle (v2) is selected so that the first-mentioned part (2a) of the shaft (2) is approximately parallel with the aforementioned principal direction of longitudinal extension of the tool component (3).

Abstract: The spade comprises a handle (1) which is preferably hollow, pivoting and lockable in different positions, by means of a pivot pin (16) jointing the shovel (12) to the handle. The handle is provided at one end on the shovel side with a plurality of surfaces (25-29) parallel to the pivot pin (16), separated by rounded angles. The shovel (12) is applied against one of those surfaces by means of the pivot pin (16) formed as an eccentric. The rotation of the pin is provided by means of a control element (17) as on arm, a lever or similar, which is linked thereto.
