Description

Garden tools

The invention relates to garden tools, namely to a weed removal fork to remove deep weeds, with a tool head and a handle holder receiving on it, the tool head having two forks spaced apart and a footrest projecting on the back.

From DE 20 2012 011 104 Ul, this type of garden tool is known, in which the forks are arranged parallel to each other by approximately the width of the handle, slightly curved forward and sharpened at the free end. At the lower end of the handle, a footrest is arranged which extends approximately perpendicular to the axis of the tool holder from the forks back and is formed in the manner of a support arch. This footrest limits the depth of the fork sink and, in the sunken state, allows the footrest to rest easily on the ground, allowing the root area to loosen and the weeds to be finally uprooted.

The well-known garden tool is suitable mainly for loosening especially the horizontally running root system. Targeted pulling of deep weeds, such as e.g. individual dandelion or plantain plants, with this garden tool is not possible. The forks of the well-known garden tools are arranged parallel to each other at a relatively wide distance and curved slightly forward. This allows the forks to be pressed into the ground on both sides of the weeds, e.g. dandelion, but simply digging or pulling out the forks does not lead to the uprooting of the dandelion along with the root. However, the forks must be lifted out of the ground with a targeted tilting and rotating motion so that the soil is loosened to such an extent that the dandelion can be pulled out of the loosened soil by hand. With skilful use of known tools, dandelion or other deep weeds are brought to the surface, but at the same time further soil and larger pieces of rubble or other plantings are dug up. This is undesirable.

From EP O 808 555 Al is known one-handed tool for loosening and crushing small areas of land with very co-planted plants, such as. balcony troughs or flower pots. CH 226 178 describes a garden tool for digging up plants with long heart roots. The garden tool has a fork with at least one fork placed on the circumference of the middle piece, which is pivoted on the pin of the support disc. DE 44 20 269 C1 describes a hand garden tool for loosening the soil in the area of deep roots with at least one holding and one fork part with at least three forks. This garden tool is not suitable for targeted digging of deep weeds. All of these garden tools do not have a footrest and are not suitable for targeted digging of deep weeds.

The object of the invention is therefore to provide garden tools, in particular weed removal forks for the removal of deep weeds, with which it is possible to dig out or uproot individual weeds of different sizes together with roots with simple handling without significantly affecting the surrounding soil. weeds. Furthermore, after removing the weeds with the tool according to the invention, the soil should be easily smoothed again in a simple way.

The object of the invention is solved by a garden tool with the features according to claim 1. Further preferred features are described in the dependent claims.

Accordingly, the forks of the garden tools shall be arranged at their upper end facing the receiving handle at least in sections adjacent to each other or spaced at a small distance parallel to each other and at their free ends facing away from the receiving handle, they extend at a spreading angle, preferably laterally to each other.

With a gap in the forks, which can be inserted into the soil to be cultivated, a wider area is formed on the one hand in the front part of the free pointed ends of the forks to capture larger weeds than e.g. dandelion and plantain. On the other hand, a tapering area is created by narrowing in the direction of the reception of the handle, in which weeds with smaller roots are captured and uprooted from the ground. Depending on the size of the weed to be removed, the forks inserted into the ground are placed on both sides of the weed root, the root being essentially trapped between the two forks. With a lever and pull movement, the weeds along with the root are then uprooted from the ground. Garden tools are e.g. suitable for use in soil, but also in gravel sand, gravel and wood-covered soil.

With regard to the forks, the stepper support is mounted directed substantially perpendicularly back to the parallel sections of the forks. In this area, good force reception from the user's foot to the tool head is possible, effectively supporting the penetration of the forks into the ground. The footrest limits the depth of penetration of the forks into the ground in accordance with its positioning along the parallel sections of the forks. The footrest is fixedly connected to parallel sections of the forks, e.g. by welding or by screw or rivet connection. Alternatively, the footrest may be attached along parallel sections of the forks in various positions, e.g. with a detachable screw connection, which makes it possible to adjust the height of the footrest above the ground.

In a useful manner, the footrest located in the area of the parallel sections of the forks can be usefully used as a lever support between the tool head and the handhold, so that the footrest fits into the ground in the backward position of the garden tool. This effectively facilitates the excavation of weeds from the ground, because on the basis of lever operation it is necessary to use only a limited manual force of the user.

The footrest has a substantially oval, especially round or elliptical metal ring formed of flat metal. In doing so, the axis extends through the center point of the metal ring parallel to the parallel sections of the forks. The contact surface by which the metal ring is mounted on parallel sections of the forks is formed flattened.

The metal ring can be dimensioned in its size so that the user can achieve efficient force transmission with the foot. In addition, it should give an optimal and central load to the foot when penetrating the ground. Therefore, the metal ring protrudes laterally over the parallel sections of the forks only to a certain extent, thus preventing accidental rotation of the garden tool due to inadvertent unilateral application of force to the footrest and the associated introduction of torque.

Spread the angle can be 5 ° to 30 ° to capture as wide a range of different root widths as possible. In the range of the 10 ° to 20 ° spacing angle, the common weed, which usually occurs in gardens, can be well uprooted. In the range of 13 ° to 19 °, dandelion and plantain are particularly well removed.

In a preferred manner, the free ends of the forks can be bent at a bending angle with respect to a plane extending through two mutually parallel sections of the forks, preferably forwards. The bent forks allow the optimal position for weed removal to be taken by predetermining the bending angle or adjusting it during insertion into the ground. In doing so, the garden tool is either pushed into the ground with just a hand on the handle or an additional support force is applied to the footrest with the foot. The footrest also limits the depth of penetration into the ground. Based on the inlet angle, which is predetermined by the bending angle, the garden tool is placed in an inclined position with respect to the weeds to be removed, with the footrest coming into contact with the ground. Based on the lever action that occurs on the footrest as a lever support against the ground, the roots to be removed can be excavated with less force applied to the handle.

The bending angle can be 20 ° to 60 °. Good lever performance is achieved in the area of the bending angle from 30 ° to 50 °, while the application of force in the area of the bending angle from 35 ° to 45 ° allows comfortable handling and good efficiency is achieved.

In particular, a stable connection between the handle and the tool head can be achieved by the handle receiving having a metal sleeve to which the forks at their upper ends are firmly connected, facing the handle reception. Alternatively, the tool head can also be attached to the holder in the form of a plug / screw connection. In this case, the parallel sections of the forks extend in the direction of the axis of the handle.

Preferably, the metal sleeve of the grip holder and the forks can be made of iron and the forks at their upper end facing the grip grip are welded to the latter. Alternatively, the forks on the metal sleeve can be mounted by means of a screw, rivet or pin connection.

When using iron in garden tools, it turns out to have a high design stability and can be easily put into the desired shape by forging. In addition, this material is advantageous in manufacture. Alternatively, steel, aluminum material or similar metals or metal alloys may be used.

According to a preferred embodiment, the parallel sections of the forks in the area of their ends facing away from the handle grip may be connected to the connecting piece and held spaced apart, the forks extending laterally to each other in the area between the connecting piece and the free ends. The connecting piece not only serves to connect the two forks, but also helps to stabilize the tool head.

In a preferred embodiment, the ends of the forks can be tapered. This makes it easier for the forks to penetrate the soil to be cultivated.

The connecting piece, arranged in the area between the forks, may preferably be shaped bluntly. Since the connecting piece is arranged in the area of the tool head in which the two forks in the direction of reception of the handle run at an angle to each other, the plants or its roots to be uprooted and accepted between the forks may rest on connecting piece. To prevent the connecting piece from cutting off the root to be uprooted, the abutment surface is formed by a blunt backrest on the connecting piece.

In a particularly simple embodiment, the connecting piece can be formed by a weld which extends at least in part between the parallel sections of the forks. Alternatively, the connecting piece may also consist of an iron or similar metal piece welded to the forks or mounted on them by means of a screw or rivet connection.

The metal ring can be forged from iron in a particularly stable design and welded to parallel sections of the forks.

According to a further idea of the invention, garden tools can in principle be used in two working positions.

In the normal working position of the weed removal fork, the footrest is turned back in the direction of the user. In this normal working position, the forks are pushed into the ground, if necessary by supporting the application of force with the foot on the footrest. The weeds to be uprooted are either pulled directly out of the ground with garden tools or are uprooted from the ground by applying a lever force to the handle, with the footrest serving as a lever support.

In the hoeing position, in which the garden tool is rotated about the axis of the handle in relation to the normal working position of the weed remover forks, the garden tool can be used in the form of an arched hoe in the soil to be cultivated. In doing so, the metal ring of the footrest serves as a sheet of hoe. In the hoeing position, garden tools with pulling and reversing can be used mainly for weeding and thus for surface loosening of the soil. In particular, in the hoeing position, the area of land that has been destroyed by weeding or leaching of weeds can be cultivated and the raised dredge repositioned.

The handle, which can be inserted into the handle holder, may consist of wood. The carcass is a very resistant material, but it can also be recycled well. Alternatively, the holder may consist of plastic or metal and be provided at its free end with a holding piece in the shape of the letter T or D. Alternatively, the holder may also be formed telescopically. This enables space-saving storage of garden tools.

The invention is further explained in more detail with the aid of the embodiments presented in the figures.

Figure 1 shows a schematic and perspective view of an embodiment of a garden tool 10 according to the invention.

The garden tool 10 serves in particular as a weed removal fork to remove deep weeds. It has a 12 tool head with a 14 handle grip that is open upwards in the user's Z direction. A wooden handle 16 is inserted into the handle holder 14. The handle is about 1 m long and equipped with a T-shaped holder at its free end (not shown).

The holder 14 of the holder has a metal sleeve made of iron, in which the holder 16 is attached by means of a conical pin and screw connection (not shown). The metal sleeve has an inner diameter of approx. 25 mm and a length of approx. 120 mm.

The tool head 12 further has two forged iron forks 18a and 18b with a 10 mm diameter fork extending substantially in the Z direction of the handle axis. The forks 18a and 18b are welded to the latter at their upper ends 22 facing the receiver 14. At their free ends facing away from the grip of the 14 handles, the forks 18a and 18b of the forks are tapered and tapered to approx. 3 mm.

Both forks 18a and 18b form a fork section 24 in the area of their upper ends 22 facing the grip 14, in which the forks 18a and 18b are spaced apart in parallel with a small distance c parallel to each other. The sections of the 24 forks are approx. 126 mm, with a spacing c of approx. 3 mm.

The parallel fork sections 24 in the region of their ends 28 facing away from the grip holder 14 are interconnected by means of a connecting piece 30. The connecting piece 30 is formed by a weld and holds the forks 18a and 18b with forks spaced cv in the fork sections 24. fork.

On the sections 24 of the forks, a perpendicularly projecting footrest 20 is arranged on the back with respect to the Y direction, which is described in more detail by means of Figure 4.

Figure 2 schematically shows a drawing of the tool head in Figure 1 of the garden tools shown

10.

Both forks 18a and 18b of the forks extend at their free ends 26, facing away from the grip holder 14, at a spacing angle a, preferably laterally in and towards the X direction of each other, thereby forming a substantially V-shaped reception for weeds, to be excavated (not shown). In this case, the V-shaped receiving area is connected to the Z direction by sections of 24 forks. The bending angle is approx. 16 °. The V-shaped receiving area is approx. 60 mm.

Both forks 18a and 18b extend in the area between the connecting piece 30 and the free V-shaped ends 26 in resp. towards direction X each. The free ends 26 of the two forks 18a and 18b are spaced apart by approx. 30 mm.

The connecting piece 30, which is arranged in the area between the forks 18a and 18b of the fork, is formed as a blunt weld.

Figure 3 shows in schematic and cross-sectional side view along the Hilli cross section the tool head 12 shown in Figure 2.

The free ends 26 of the forks 18a and 18b are at a bending angle β with respect to the plane E, which extends through two mutually parallel sections 18 of the forks, and which in Figure 3 are positioned perpendicular to the drawing plane bent forward in the Y direction. Bending angle β is approximately 40 °.

Figure 4 is a schematic representation of the tool heads shown in Figures 2 and 3 from below.

With respect to the forks 18a and 18b of the forks, the footrest 20 is directed backwards in the Y direction. It has a substantially oval, iron-forged flat metal ring 34 whose axis A (Figure 3) extends through the center point M parallel to the parallel sections 24 of the forks forks in the Z direction. The metal ring 34 has a flattened contact surface 36 with which the metal ring 34 is welded to parallel sections 24 of the forks.

The footrest 20 is in the normal working position of the weed removal fork facing backwards in the Y direction in the direction of the user. In the hoeing position (not shown), which is rotated around the handle 16 relative to the normal working position of the weed removal fork, the working head 12 with the metal ring 34 can be used as an arcuate towing hoe in the soil to be treated.
