Description

Technical field

[0001] The invention relates to a pendulum hoe according to the preamble of claim 1. State of the art

[0002] Such pendulum hoes are already known and in use in a variety of forms and designs. For example, US Patent 4,377,212 A discloses a pendulum hoe consisting of an elongated handle with a vertically inverted U-shaped support frame attached to its lower end. A second, upright, vertically arranged U-shaped shovel frame with a shovel section is pivotally attached to the support frame. This shovel section is pulled back and forth through the soil being worked, and its movement is limited by a rod element located between the side arms of the frames.

[0003] Reference is further made to US Patent 4,093,031 A. This patent discloses a pendulum hoe having a U-shaped blade attached to the fork of a handle for limited mobility. The inward-facing flanges of the blade engage in hourglass-shaped openings in the fork arms, the flanges being held between reinforcing bars that extend through the openings, providing the blade with strength, wear resistance, and limited elasticity. The fork consists of two separable parts, allowing each component of the hoe to be replaced.

[0004] Reference is also made to DE 606 411 A, which discloses a pendulum hoe in which the frame-like knife is articulated to a U-shaped bracket firmly connected to the handle, wherein pivotable tabs with stops to limit the pivoting movement of the knife are arranged on the bracket, to which the knife is easily replaceable.

[0005] The DE 199 54 039 A1 pendulum hoe is also used for loosening soil near the surface and for mechanical weed control. It consists of a blade that is moved back and forth at a predetermined depth, close to the ground. The blade is clamped in a holder that is rotatably mounted on a rail within a certain angular range, with the blade positioned several centimeters away from its axis of rotation. As the pendulum hoe moves back and forth, the blade tilts to different angles relative to the soil surface. The angles for the forward and reverse movements can be set independently, determining the working depth and the amount of displaced soil. This is achieved using a complex double-spring mechanism with stop surfaces.

[0006] Reference is further made to US 8,079,423 B2, which also discloses a pendulum hoe with a blade assembly, wherein the blade assembly comprises a mechanism connected to the lower end of the handle and a pivoting mechanism that pivots the scraping blade relative to the handle. The blade assembly connects the scraping blade to the handle in a manner that leaves the spaced area above both ends of the blade unobstructed, allowing the scraping blade to slide under a plant without damaging it and under an object to remove weeds and grass.

[0007] Finally, reference is made to DE 28 27 506 A1.Therein is disclosed a pendulum hoe with a handle, wherein a fork attached to one end of the handle has two legs projecting beyond the end of the handle at a parallel distance from each other and slots passing through them, arranged obliquely to their longitudinal direction, which run horizontally in the normal working position of the handle, thereby forming a blade with two upwardly angled legs and inwardly angled tabs at the upper ends of the legs, which project inwards towards each other through the slots, and a holding and stiffening part with double end pieces projecting through the slots and having outwardly directed openings for receiving the tabs, wherein the combined thickness of the tabs and the double end pieces is less than the width of the slots in the vertical direction, so that the blade can pivot in a limited range relative to the fork. Object of the invention

[0008] The object of the present invention is to overcome the disadvantages of the prior art. In particular, it aims to provide a pendulum hoe that combines an attractive appearance with an exceptionally long service life while maintaining the lowest possible manufacturing costs. Solution to the task

[0009] The features according to claim 1 lead to the solution of the problem. Advantageous embodiments are described in the dependent claims.

[0010] The pendulum hoe according to the invention is an innovative garden tool specifically designed for the effective weeding of weeds. It consists of a combination of a handle socket, a hoe runner, and an intermediate runner support. This design allows for efficient handling, as the hoe is pulled or pushed across the ground with a back-and-forth motion. The hoe runner penetrates the topsoil and reliably removes unwanted weeds.

[0011] The handle holder securely holds a handle used as an extension of the tool. The handle is positioned in a slot at the other end of the holder and secured with a handle fixing screw. This screw passes through the holder and the handle itself, ensuring a firm fit during operation. The ergonomic design of the handle holder ensures comfortable use, even during extended periods of operation.

[0012] Between the handle socket and the heel runner is a runner holder, which acts as the central element of the construction. It is designed as a U-profile, consisting of a base strip and two side strips that are aligned towards the heel runner.

[0013] The base strip forms two parallel mounting strips that extend from the hoe skid and project into the handle socket. This projection protects the pivoting components from dirt and thus from premature wear. These mounting strips are equipped with circular openings connected by a freely rotating sleeve. This sleeve allows for frictionless movement of the hoe in both working directions.

[0014] The handle holder is equipped with through-holes at its first end. A connecting bolt is guided through these openings, as well as through the sleeve and the circular through-holes of the mounting strips. This creates a pivoting connection between the handle holder and the skid bracket. The connecting bolt can be a screw secured with a nut and washer. This design not only ensures stability but also prevents the screw from loosening unintentionally, without restricting the hoe's movement.

[0015] The base strip thus forms two parallel receiving strips that project away from the heel runner, with the receiving strips projecting into the handle recess, each receiving strip having a circular opening. The receiving strips form a rounded end on the side inclined away from the base strip. An advantage of this design is that it allows for swiveling without snagging.

[0016] The two circular openings are functionally connected by a freely rotatable sleeve. This sleeve ensures smooth and long-lasting swiveling.

[0017] The handle holder has two through-holes at its first end facing the base strip. A connecting bolt extends through these two through-holes and the sleeve, and thus also through the two circular through-holes, thereby pivoting the handle holder relative to the skid bracket. In one embodiment, the bolt can have heads with anti-slip stops at both ends, which can be welded together. However, another embodiment provides a screw whose head forms the anti-slip stop on one side and a reversible nut with or without a washer, or another type of anti-slip stop, on the other. For example, a snap-lock pin can also be used.

[0018] The hoe's skid is designed to stand at a specific angle to the ground, efficiently loosening weeds without unnecessarily compacting the soil. It is attached to the side strips of the skid bracket with screw connections, allowing it to be replaced if needed. This flexibility makes the pendulum hoe particularly durable and adaptable to various gardening requirements.

[0019] A notable feature of the handle holder is the two angled stop edges on one end face of the handle holder. The first stop edge is designed for a first working direction towards the user, while the second stop edge is designed for the opposite direction, away from the user. In a preferred embodiment, both stop edges have an identical angle of approximately 15°, which supports the pendulum motion and enables precise guidance of the hook runner. However, different angles between 10° and 30° are also possible for the two stop edges. For example, the first stop edge could have an angle of 25° and the second stop edge an angle of 10°. Preferably, however, they have an identical angle.

[0020] The two angled stop edges, in combination with the pivotably arranged handle mount, ensure that there is no need for any spring construction, which experience has shown to be a weak point for the service life of pendulum hoes described in the prior art.

[0021] The base of the skid holder also has two central protrusions that contribute to the stability and strength of the entire construction. These serve as stop surfaces for the first and second stop edges.

[0022] The pendulum hoe is ideal for maintaining gardens, flowerbeds, and other cultivated areas. Thanks to the swiveling connection between the handle and the hoe's skid, the user can flexibly operate the hoe in both directions. The hoe's skid easily penetrates the soil to remove weeds from the top layer, leaving behind a clean, loosened surface.

[0023] Thanks to its well-designed construction, the pendulum hoe is not only efficient but also easy to maintain. The replaceable hoe head and the robust connection of all components ensure a long service life for the tool. Therefore, the pendulum hoe is a valuable tool for every hobby gardener and professional user who values ​​reliable and precise work.

[0024] The handle attachment forms a curve towards a surface at its first end. The surface is understood to be the area over which the hoe skid is pulled back and forth during proper use. Character description

[0025] Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawings; these show in: Fig. 1 a view from an oblique angle above of a pendulum hoe according to the invention 1; Fig. 2 an enlarged view of part of the Fig. 1; Fig. 3 an exploded view of the Fig. 2; Fig. 4. A further enlarged view of part of the Fig. 2; Fig. 5 a sectional view of the Fig. 4. Example of implementation

[0026] In Fig. Figure 1 shows a pendulum hoe 1 with a handle receptacle 2, wherein a handle 21 is attached in the handle receptacle 2. The handle 21 is fastened to the handle receptacle 2 at a second end region of the handle receptacle 2 by means of a handle fastening screw 20 arranged through the handle receptacle 2 and the handle 21.

[0027] Furthermore, a skid holder 4 is arranged at a first end region of the handle receptacle 2. The skid holder 4 is designed as a U-profile, which consists of a base strip 5 and two side strips 6.1, 6.2 projecting in the same direction towards a heel skid 3.

[0028] The pendulum hoe 1 is a garden tool used, for example, to weed by being pulled back and forth across a surface, with the angled hoe blade 3 removing weeds from the topsoil. To do this, the hoe blade 3 is pulled in a first working direction 22 or pushed in a second working direction 23 by a person using the handle 21. The position of the user, standing on the surface being worked, thus defines the respective working direction 22, 23.

[0029] This is in the Fig. 1 It is still clearly recognizable that the skid holder 4 is arranged between the handle receptacle 2 and the heel skid 3.

[0030] In the Fig. 2, due to the enlarged view, now better shows how the handle holder 2 and the skid holder 4 are constructed in detail.

[0031] The base strip 5 forms two parallel receiving strips 7.1, 7.2 which project away from the heel skid 3, wherein the receiving strips 7.1, 7.2 project into the handle receptacle 2, in particular into the first end region of the handle receptacle 2. The first end region and the second end region are defined within the scope of the invention as 10-30% of the total extent of the handle receptacle 2.

[0032] The heel skid 3 is interchangeably arranged on the side strips 6.1, 6.2 by means of screw connections not described in detail.

[0033] The stem receptacle 2 has a receiving slot 19 for the stem 21 in the second end region pointing away from the base strip 5.

[0034] The handle holder 2 forms a curvature 24 towards a substrate in its first end region. Within the scope of the invention, the substrate is defined as the surface to be worked when the pendulum hoe 1 is used correctly.

[0035] The Fig. 3 further facilitates the detailed understanding of the invention through the exploded view.

[0036] It can be clearly seen that the receiving strips 7.1, 7.2 each have a circular through-opening 8.1, 8.2, wherein the two circular through-openings 8.1, 8.2 are connected by a sleeve 9 which is freely rotatable within them, wherein the handle receptacle 2 has two through-openings 10.1, 10.2 at the first end region pointing towards the base strip 5, wherein a connecting bolt 11 extends through the two through-openings 10.1, 10.2 and the sleeve 9 and thus also through the two circular through-openings 8.1, 8.2 and thereby arranges the handle receptacle 2 pivotably to the skid holder 4.

[0037] In the embodiment shown here, the connecting bolt 11 is replaced by a screw 17, which is fastened by means of a nut 18 with an associated washer 25, or is designed as such.

[0038] The screw 17 is arranged such that it passes through the two through-openings 10.1, 10.2 and the sleeve 9 and thus also through the two circular through-openings 8.1, 8.2, thereby arranging the stem receptacle 2 pivotably to the skid holder 4 and the nut 18 with the washer 25 serves as a backstop so that the screw 18 cannot slide out unintentionally, but ensures pivotability.

[0039] In the Fig. 4 can also be clearly seen that the stem receptacle 2 has or forms on its end face 12 pointing towards the base strip 5 a first angled stop edge 13 in the first working direction 22 and a second angled stop edge 14 in the second working direction 23.

[0040] In the illustrated embodiment, the first angled stop edge 13 and the second angled stop edge 14 are identical and have an angle of 15°. This angle results from the fact that the end edge 12, in the areas of the angled stop edges 13 and 14, extends away from the base strip 5. This is achieved by cutting or removing the end edge 12 at an angle at the relevant points of the stop edges 13 and 14. The degree value described above indicates the angle of this angled cut.

[0041] The Fig. Figure 5 further facilitates understanding of the invention through the sectional drawing. Fig. Figure 5 clearly shows how the sleeve 9 is rotatably arranged in the circular through-openings 8.1, 8.2 of the two mounting strips 7.1, 7.2, thus connecting the two mounting strips 7.1, 7.2, at least functionally. The screw 17 is arranged such that it extends through the two through-openings 10.1, 10.2 and the sleeve 9, and thus also through the two circular through-openings 8.1, 8.2, thereby pivoting the handle mount 2 relative to the skid holder 4. The nut 18 with the washer 25 serves as a backstop, preventing the screw 18 from unintentionally sliding out and ensuring its pivotability.

[0042] In the Fig. 4 and Fig.It should also be noted that the base strip 5 forms a first bulge 15 in the first working direction 22 projecting away from the receiving strips 7.1, 7.2 and a second bulge 16 in the second working direction projecting away from the receiving strips 7.1, 7.2.
