Definitions

  • the present invention relates to a device for moving soil material, comprising a body to be introduced into the soil, which body is provided at one end with a shaft, which shaft is provided at its other end with torsion means, said body defining a flat surface and having a pointed end.
  • This patent describes a device for turning over soil material, consisting of two fork teeth located opposite one another with a blade placed between them.
  • This blade is provided with a pointed end. By means of said end it is possible to penetrate into the soil material.
  • the device described in said US Patent 2 855 668 is relatively difficult to handle and expensive to produce. Moreover, when the device is rotated in the soil, appreciable damage is caused, in particular by the blade section, to living organisms, such as earthworms, present in the soil material.
  • Devices of this type are used to loosen soil material in, for example, gardens.
  • the aim of the present invention is further to improve the device described in US Patent 2 855 668.
  • the body consists of a bent section of solid wire or tube, at least one triangular opening being delimited inside the periphery of said wire section, one corner of said triangular opening defining the pointed end.
  • the invention is based on the insight that a pointed end of the turning- over device is desirable in order to penetrate easily into the soil using a turning-over device of this type.
  • a first group is that in which the wire section is joined at one end to the shaft and is free at the other end.
  • This free end can, as it were, cut through the soil material.
  • this free end is preferably arranged so that it is directed toward the shaft.
  • the free end is preferably sharpened to a point in order to provide a sharp surface.
  • the thickness of the wire material is, for example, 8 mm or 10 mm, adequate rigidity can be obtained to achieve loosening in an average soil material.
  • the section composed of solid wire or tube is fitted such that an unbroken surface is defined.
  • the ends of the section composed of solid wire or tube are joined to or merged into the shaft.
  • the shaft is of tubular construction, it is particularly simple to insert the free ends of the body, which, for example, is composed of wire material, into said tube and to join it thereto, for example by means of welding or compression.
  • a fork tooth can also be fixed to the shaft. It is also possible to fit more than one fork tooth. Such fork teeth can be fixed to, for example, a tube in the same way as described above for the free ends of the body.
  • the torsion means or handle of the device described above can be constructed in various ways. For instance, it is possible to construct these means as ratchet means, as a result of which the position of the user with respect to the device according to the invention can always be adjusted in an optimum manner.
  • the device preferably consists of one part.
  • the end of the body joined to the shaft can indeed be a simple extension of the wire material, which likewise simply continues, by bending, at the transition between shaft and torsion means.
  • FIG. 1 shows a perspective view of a first embodiment of the device according to the invention
  • Fig. 2 shows a top view of the device according to Fig. 1;
  • Fig. 3 shows a second embodiment of the invention
  • Fig. 4 shows a third variant of the present invention.
  • FIG. 1 the turning-over device according to the invention is indicated in its entirety by 1.
  • This device comprises a shaft 2, to the top of which a handle 3 is fitted.
  • shaft 2 is provided with a turning-over body 4.
  • this body comprises an essentially triangular wire section which is provided with a point 5 directed downwards.
  • This wire section consists of solid wire material.
  • the sections of wire material which are inserted in the tube from which the shaft 2 is made are joined to one another by means of welds 6.
  • a weld can also be made at the cross where the various wire sections come together.
  • Fork tooth 9 is chamfered somewhat.
  • the construction shown here can be introduced into the soil without too much resistance. This is achieved by the pointed end 5. Moreover, the point promotes drainage in wet ground.
  • the closing-over body 4 is relatively strong, so that relatively thin wire material, such as 8 mm steel, can suffice.
  • the turning-over body is open on the inside, there is no risk of distortion during turning, such as is known in the prior art in the case of constructions with a blade. Moreover, small animals are protected and the production of the turning-over body is particularly simple.
  • Fig. 2 shows a top view of the device from Fig. 1. It can be seen from this figure that handle 3 is positioned at a small angle with respect to the plane of body 4. This feature is provided because a user tends to place his or her foot on the top of turning-over body 4 when introducing the latter into the ground. The turning-over body 4 acts as a sort of spade when it is introduced into the soil material. Consequently, this 'spade' will be placed in a specific position. Positioning handle 3 at a small angle with respect thereto enables the user to exert an optimum force.
  • Fig. 3 shows a further embodiment of the device according to the invention.
  • the device shown in this figure is indicated in its entirety by 11.
  • This device consists of a shaft 12.
  • the handle 13 consists of a ratchet, so that, on the one hand, the position with respect to shaft 12 can be freely chosen and, on the other hand, optimum engagement of the turning-over body indicated by 14 can always be provided.
  • the pointed end is indicated by 15.
  • the construction shown here has no fork teeth. This has been found not to be necessary, depending on the nature of the soil.
  • the turning-over body 14 is joined to shaft 12 at one end only and at the other end is provided with a pointed free end 15, provided with a free projecting section 29. The latter can be chamfered in order to provide a sharp cutting surface.
  • the wire material chosen for this embodiment will be somewhat thicker than that for the other embodiments, for example 10 mm. This, of course, depends on the strength of the wire material used.
  • the turning-over device indicated by 21 consists of a continuous section of wire material. This section of wire material forms both shaft 22 and handle 23.
  • the turning-over body 24 is joined to form an unbroken whole by means of weld 25.
  • Fig. 3 is particularly simple to produce and is found to be particularly effective in practice.

Abstract

Dispositif permettant de retourner les matières constitutives du sol. Ce dispositif est composé d'une tige (2, 12, 22) portant à l'une de ses extrémités une poignée de torsion (3, 13, 23), et à l'autre extrémité une section coudée constituée d'un fil plein ou d'un tube (4, 14, 24). Cette section est coudée de telle manière qu'au moins une ouverture triangulaire est délimitée dans la section constituée du fil plein ou du tube. Par ailleurs, ladite section est pourvue d'une extrémité libre pointue (5, 15, 25) facilitant l'enfoncement du dispositif dans le sol.
