FR2844422A1 - Garden fork or spade has lifting foot above main teeth and secondary lower teeth which are shorter - Google Patents

Abstract

The garden fork has a main working plane formed by tines or a metal plate welded to a lifting foot (5) slightly angled and above the main plane. The lifting foot has a socket (3) to receive the handle shaft (4). Secondary teeth (7) are welded to the head below the main plane and are shorter than the main teeth.

MANUETLLE SPOKER

  The present invention has for its object a MANUAL SPREAD TO PUT DOWN heavy and packed earth in the fall and spring thanks to specific characteristics, never having to raise the spade, which remains in permanent contact with the ground and thus avoids the most of the user fatigue. In fact, we have been finding for a very long time on the market full-spade spades or other fork-tines With "classic" teeth whose morphology (handle at the level of the teeth plane) does not allow sufficient lump of the clod of earth , it is then that 10 the plowman must take charge of the rest of the muscular maneuver by leaning strongly forward, bending the legs in order to complete the root ball by lifting it to leave it

  fall back into the gauge, hard work.

  The purpose of the proposed invention is therefore to eliminate these drawbacks by the following specific features:

DESCRIPTION.

  1 / The support crosspiece on which the main teeth are welded is raised by a connecting lug which will receive the handle, this extension of several centimeters is intended to create a dice. 20 port of the handle above the plane of the teeth main teeth and will also be slightly tilted above the main teeth; 2 / At the top of this extension tab will be welded a sleeve fixing sleeve; 3 / The elevation tab being slightly inclined towards the front in order to create a slight convergence of the axis of the handle towards the main teeth, this in order to allow more amplitude to the planing movement and that the end of the handle is not found

  too low at the end of travel at the correct working height for the user.

  keep him from stooping; 4 / The secondary teeth will be fixed to the support crosspiece of the main teeth, and will start in a regular curve until their low point under the main teeth and parallel with them; / These secondary teeth have the mission of increasing the general offset of the tool, the curvature of these teeth being flattened As far as its low point in order to create more lift in the tool and reduce any possible sinking into the ground, unlike at the autèrieure part, the front part will be flattened in the vertical direction bottom-top of section "knife blade" to split the earth on the back of the main teeth during the plowing maneuver, thus preparing the next pass of the spade; 6 / At this stage of the planing maneuver, it will be noted that the secondary teeth are situated several centimeters from the main teeth and inside the projection projection thereof in order to obtain, by a less lift, an effect of 'unstable balance which will allow to easily carry out the maneuver of earth pouring LATERALLY to the left or right of the spade, by means of a very slight lateral impulse of rotation on the handle; 7 / Finally another advantage of the secondary teeth, they begin to split the earth in the back of the main teeth at each plowing operation, facilitating the raising of the teeth to the next pass, allowing to plan much more soil each time, which will

  give a lot of speed to plowing.

  8 / Manual doe to knock down * to plow the compacted heavy soil without ever lifting the doe which remains in permanent contact with the ground to avoid any fatigue to the user; comprising two rows of superposed and parallel teeth welded to a support beam , the main teeth several centimeters above the secondary teeth, the support crosspiece has a starting post slightly tilted forward above the main teeth, at the top of the rear side extension of the tool is welded the socket fixation of the handle according to the angle of inclination of the raising leg making the axis of the uanche converge towards the main teeth. Finally, the secondary teeth have their front part curved horizontally flattened Up to their low point, then that the front part is flattened in the vertical direction with a sharp edge above to cut the earth representing a section like "knife blade" Finally the the main teeth can be replaced by a solid iron 35 better suited to certain types of lighter earth, the secondary teeth being welded to the top of the solid iron at the foot rest, and all other characteristics applied to the tarpaulin

  manual knock described above applicable to him.

Claims (3)

CLAIMS Manual log to knock down according to claim 1 comprising two planes of superimposed teeth, main teeth above and secondary teeth below are connected on a common support crosspiece (6 FIG 1) the main teeth (1 FIG 1) are larger that the secondary teeth (7 FIG 1) and (7 FIG 2), the support crosspiece (6 FIG 1) being raised by a fixing lug inclined towards the teeth (3 FIG 1) and several centimeters above du.plands main teeth, the fixing sleeve (5 FIG 1) of the handle is welded to the upper part of the raising tab, finally the handle (4 FIG 1) is connected to the tool for handling.   2 / manual spade to break down according to claims 1 comprising a   raising leg of the support cross member (3 FIG 1) and slightly inclined above the main teeth.   3 / manual spade to knock down according to claims 1 important one   fixing sleeve (5 FIG 1) welded to the upper part of the raising leg (5 FIG 1) in order to obtain a maximum offset of the handle as well as a convergence of the axis of the handle towards the main teeth 20 (2 FIG 1) 4 / manual spade to break down according to claim 1 comprising a handle (4 FIG 1) fixed to the tool by means of a connecting sleeve (5 FIG 1) welded to the top of the connecting tab (3 FIG 1) in order to obtain a large offset of the handle relative to the plane of the 25 main teeth, in addition, the raising tab being slightly inclined forwardly above the main teeth, the axis of the handle will be slightly convergent towards the main teeth allowing more   amplitude to the planing maneuver by lowering the handle towards the ground, the handle remaining higher above the ground at the end of the race in order to avoid the user from falling.   / Manual spade to break down according to claim 1 comprising a number of so-called secondary teeth shorter than the main teeth are welded to the support crosspiece and directed in a regular curve (8 FIG 1) to their lowest point & several centimeters below35 main teeth; the front part of these teeth will be fairly flattened Up to the lowest point (9 FIG 3) to increase the general lift of the tool during planing; finally the front part of these teeth being flattened in the vertical direction (10 FIG 4) with a cutting edge & its upper part   in order to split the earth on the back of the main teeth at each plowing operation.   6 / manual spade to break down according to claim 1 comprising secondary teeth under the main teeth and inside the projection of these (11 FIG 5) to create an unstable balance of the tool and facilitate lateral pouring of the earth to the left or right of the tool by a very slight lateral impulse of rotation on the handle.
