Abstract

Device for reducing the effort of lifting the soil when digging. It mainly comprises a short cable attached by one end 2 to the bush of the fitting or to the bottom of the handle of the spade, and having a grip 3 at its other end; this grip is held by the front hand, instead of this hand having to grab the handle closer to the ground.

Description

Description
La présente invention a pour objet de réduire dan. une mesure appréciable l'effort de soulevement de la terre avec une beche ou analocue. Description
The object of the present invention is to reduce dan. an appreciable measure of the effort of lifting the earth with a beak or the like.

Elle consiste
1. A attacher au-dessus du fer, a partir du bord supérieur de selui-ci sur la douille ou le manche,
En un ou deux points de la douille ou du i-ancre,
Ce point ou ces poir.ts d'attache étant solidaires de la douille ou
du manche, ou étant solidaires d'une bague tournant autour de l'axa de
manche, sans coulissement,
Et ce point ou ces points d'attache pouvant se trouver à l'avant de
l'outil, ou sur les cotés, symétriquement par rapport au plan médian ae
l'outil ou sensiblement, ou à l'arrière,
L'une des extrémités d'un câble souple, élastique par lui-même ou par ressort interposé, ou non élastique ou ou d'une tige rigide, avec ou sans ressort interposé, articulée sur la douille ou le manche par une rotule ou analogue, ou par bague tournant autour de l'axe du manche, sans coulissernent, et rotule ou analogue solidaire de cette bague.It consists
1. To attach above the iron, starting from the upper edge of this one on the socket or the handle,
In one or two points of the sleeve or the i-anchor,
This point or these attachment points being integral with the socket or
of the handle, or being integral with a ring rotating around the axis of
handle, without sliding,
And this point or these attachment points can be at the front of
the tool, or on the sides, symmetrically with respect to the median plane ae
the tool or substantially, or at the back,
One of the ends of a flexible cable, elastic by itself or by interposed spring, or non-elastic or or of a rigid rod, with or without interposed spring, articulated on the sleeve or the handle by a ball joint or the like , or by ring rotating around the axis of the handle, without sliding, and ball joint or the like secured to this ring.

Le câble ou la tige se termine a son autre extrémité par une poignée, transversale ou longitudinale. The cable or rod ends at its other end with a handle, transverse or longitudinal.

La longueur du cable ou de la tige est approximativement telle que la main gauche, s'agissant d'un droitier, et la main droite, s'agissant d'un gaucher, puisse saisir la poignée lorsque l'on se tient debout, l'outil tenu verticalement, le tranchant du fer sur le sol. The length of the cable or rod is approximately such that the left hand, being a right-handed person, and the right hand, being a left-handed person, can grasp the handle when standing upright. tool held vertically, the edge of the iron on the ground.

2. A relier élastiquement la poignée du câble ou de la tige à la partie supé rieure du manche, de manière que le cable ou la tige, et la poignée, soient automatiquement appliqués sur le manche lorsque la poignée est lachée. 2. Elastically connect the cable or rod handle to the upper part of the handle, so that the cable or rod, and the handle, are automatically applied to the handle when the handle is released.

3. A modifier l'extrémité libre du manche de la maniere suivante
Cette extrémité est épaissie dans le plàn médian de l'outil, soit en avent seulement, soit en arrière seulement, soit en avant et en arrière 4 le sois, - sur une longueur suffisante pour que la paume de la main arrière ait un contact satisfaisant, et pour que la main assure facilement, par l'action des doigts d'une part, et du pouce d'autre part, sur les plats latéraux, le maintien de l'outil lorsque le fer est soulevé au-dessus du sol avec sa charge de terre ; et pour que la main commande ensuite le renversement de la terre.3. To modify the free end of the handle in the following way
This end is thickened in the median plane of the tool, either in advance only, or in rear only, or in front and behind 4 it is, - over a sufficient length so that the palm of the rear hand has satisfactory contact , and so that the hand easily ensures, by the action of the fingers on the one hand, and the thumb on the other hand, on the lateral flats, the maintenance of the tool when the iron is lifted above the ground with its earth load; and so that the hand then controls the overturning of the earth.

Bien entendu, les formes existantes, en boule, ou poignée transversale, peuvent entre conservées. Of course, the existing shapes, in a ball, or transverse handle, can be preserved.

4. L'articulation du câble ou de la tige sur la douille ou le manche peut aussi comprendre un triangle idéal indéformable, dont l'un des cites, pris cor--e axe, cet axe étant perpendiculaire au plan médian de l'outil, ou sensiblement, et courrant dans une fourrure solidaire de la douille ou du anche. Les deux autres cotés, de méne longueur ou sensiblement, et de longueur convenable pour que leur angle commun, étant normalement le plus aigu, se présente en avant de l'outil, à une distance du manche égale a l'épaisseur de la terre chargeant normalement le fer, ou sensiblement.Le câble étant attaché, ou la tige etant articulée, sur cet angle. Le renversement de la terre est ainsi plus facilement controlé, grâce au relevement du point de suspension. 4. The articulation of the cable or the rod on the socket or the handle can also include an ideal non-deformable triangle, one of the quotations of which is taken on the axis, this axis being perpendicular to the median plane of the tool. , or substantially, and running in a fur integral with the sleeve or the reed. The other two sides, of the same length or substantially, and of suitable length so that their common angle, normally being the most acute, is in front of the tool, at a distance from the handle equal to the thickness of the loading earth. normally the iron, or substantially. The cable being attached, or the rod being articulated, on this angle. The overturning of the earth is thus more easily controlled, thanks to the lifting of the suspension point.

5. S'agissant d'un cable souple, ce câble peut être doublé pour passer dans une poulie solidaire de l'angle du triangle, intérieurement ou extérieurement a cet angle, ou solidaire de tout autre point d'attache sur la douille ou le manche. Les deux extrémités de ce câble sont attachées a la poignée, l'une a un bout, l'autre a l'autre bout. Un des bouts de la poigne servant aussi de point d'attache au lien élastique avec la partie supérieure du manche. La poignée est ainsi appliquée longitudinalement sur le manche lorsqu'elle est lachée. 5. Being a flexible cable, this cable can be doubled to pass in a pulley integral with the angle of the triangle, internally or externally at this angle, or integral with any other point of attachment to the socket or the handle. The two ends of this cable are attached to the handle, one at one end, the other at the other end. One of the ends of the handle also serving as a point of attachment to the elastic link with the upper part of the handle. The handle is thus applied longitudinally to the handle when it is released.
