Garden tools for various gardening tasks

Description

[0001] This invention relates to a garden tool for carrying out various gardening tasks, and in particular for creating furrows for subsequently planting seedlings, bulbs, and saplings. Various tools are currently used for gardening work, such as: spade, shovel, rake or digging fork, hoe, weeder, shears, axe, hatchet or pruning shears, along with a watering can and a ladder.

[0002] A garden hoe is known from US patent 1,234,485. This hoe comprises a handle and a sleeve 2 with a handle 4 at the front of the sleeve. This handle 4 is bent backward at an angle of approximately 110° to the axis of the sleeve, and the working tool, made of sheet steel and functioning as a hoe, is screwed to this handle. This sheet steel is channel-shaped and tapers to a pointed end. A reinforcing rib 6 is formed along a central section, featuring a hole 8 and, further down, a slot 7. This allows for the secure and firmly attached mounting of a plow head 9, which is placed on the front and screwed to the hoe.The plow head 9 consists of a single piece of sheet metal, comprising a plow point 9a, a forming board 9b, and a land side 9". The forming board 9a is bent outwards to turn the soil in the usual manner, while the lower, horizontal edge of the land side 9a is rolled inwards, forming a tubular outer surface to reinforce this side and to guide the plow's movement. This tubular outer surface serves to assist in guiding or steering the plow's movements. Instead of such a plow head 9, an arrow-shaped plow with equal outward-projecting wings on both sides can be screwed on. These wings then lie firmly on the soil along their length, allowing the soil to be swept. Depending on whether this tool is to be used as a hoe, a plow, or a sweeper, the appropriate tools must be mounted separately on the hoe.FR 748 755 shows a cultivator in the form of a multi-share plow, which is pulled through the soil by hand. The plowshare is the cutting edge of a plow. The term "share" is also imprecisely used to refer to the entire plow body. One speaks of... multi-furnishedPloughing actually refers to ploughs with multiple bodies. The difficult problem with these hand ploughs or cultivators is to adjust them so that they maintain the same depth of penetration into the soil at all times, which is difficult to achieve in practice. The depth of penetration into the soil depends on the shape and arrangement of the share or shares. The solution according to this FR 748 755 is that the cultivator is designed to have multiple shares, e.g., three shares, one of which is positioned between the other two and offset forward, thus forming a front share, and the two rear shares are then offset laterally to this front share. The shares are each forged in one piece with the supports 2 or welded to them.In the illustrated embodiment, the plowshare supports 2 meet at a point 3, where the sleeve 4, which receives the neck of the instrument, is also attached. The plowshares, which are forged in one piece with their supports 2 or cut from sheet steel, are slightly bent into a herringbone pattern. The front part 5 forms an acute angle of approximately 40° to 60°, to which a toothed part 6 is attached, the outer edges of which run parallel to each other. At their rear end, the plowshares have a dovetail shape. When this cultivator is pulled through the soil, it remains in the same working plane without requiring any special guidance or pressure. Each of the shares is slightly curved in its central plane, and its supports are connected to it from below in a stepped fashion, with the connection point located approximately at the share's center of gravity.Due to the shape and arrangement of the components, a consistent penetration depth is achieved, with this effect primarily due to the dovetail shape of the shares. The share supports are otherwise tapered to a sharp edge at the front in their curved sections. US2016 / 0157408 shows a hand tool for simultaneously creating parallel furrows in a humus bed. How to... Figure 1 Several arrow-shaped plows 22 are arranged side by side on a cross-section 18, and this cross-section can be pulled through the soil by a drawbar 12 projecting at a right angle to it, with a handle 10 running transversely to it at its upper end. Bolts 28 protrude upwards from the cross-section 18, onto which weight discs 40 can be placed, as can be seen in Figure 1 The tool is designed to push the four arrow-shaped plows 22 into the soil. It can only be used as a multi-share plow.

[0003] In light of the above solutions, this invention aims to provide a Universal- To create garden tools which several conventional It can replace existing tools and is also very efficient in its application. Unlike the tools shown in the aforementioned documents, it can be used as a hoe, a scraper for pulling and pushing, and a plow, creating furrows when used as a plow, all without requiring any modifications to the garden tool.

[0004] This problem is solved by a garden tool according to the preamble of claim 1 with its characterizing features.

[0005] This garden tool and its use are described and explained using the figures.

[0006] It shows: Figure 1: The garden tool in a side view; Figure 2: The garden tool in an enlarged view of the front tool part made of steel; Figure 3: The garden tool in an enlarged view of the front tool part made of steel with the opposite side Figure 2 the handle rotated approximately 180°; Figure 4: The garden tool seen from a front and top angle; Figure 5: A garden tool at the front end of the handle, with plow-like curved wings for turning humus, seen from the side and from a top angle; Figure 6: The garden tool after Figure 6Figure 7: The garden tool in use for breaking up clumps of humus and for spreading and smoothing a layer of humus; Figure 8: The garden tool in use as a scraper; Figure 9: The garden tool in use as a plow for creating a furrow for later planting of seedlings or bulbs, or for sowing seeds; Figure 10: The garden tool seen from above and its outward curvature in the upper area; Figure 11: The garden tool seen from the side, its outward curvature in the upper area; Figure 12: The garden tool in use for plowing; Figure 13: A garden tool with a blade screwed onto the lower edge; Figure 14: The garden tool after Figure 13 with the blade screwed to the lower edge, and next to it the blade lying down and shown separately.

[0007] First, the Figure 1The garden tool is shown in a side view. It consists of a wooden handle 1 approximately 1100 mm long and, at the front, a tool made of sheet steel, preferably stainless chromium steel. At the front end, the handle 1 is enclosed by a steel sleeve 7. This sleeve 7 is approximately 100 mm long and encloses the wooden handle 1, which is approximately 35 mm thick. A round bar 3 is welded to the handle 1. This bar extends a short distance along the front end of the sleeve 7 and is then bent at an angle of approximately 80° ± 5°, thus extending downwards and backwards from the sleeve 7 and the handle 1 at this angle. A sheet of steel 4, bent at a 90° angle, is welded to this round bar 6, which extends away from the handle, with the inside of its edge 10 abutting the round bar 3. The steel sheet 4 forms a wing on each side of its bend.Here you can only see wing 5, which faces the viewer, but which does not run in the plane of the drawing sheet, but rises upwards from the round rod 3 out of the plane of the sheet.

[0008] The Figure 2 Figure 1 shows an enlarged view of the front steel part of the garden tool. Clearly visible are the collar 7 at the front end of the handle 1 and the welded-on round steel bar 3, which extends from the front end of the collar 7 to the rear and curves outwards at a right angle halfway along the length of the collar 7. It continues inside the welded-on steel plate 4 until it is close to the lower, outer edge of the plate. Again, only the wing 5, which faces the viewer, is visible. This wing runs at an oblique angle to the handle 1, so that the two wings form an arrow pointing from the front end of the handle 1 towards the rear end of the handle 1.

[0009] In Figure 3This garden tool can be seen in an enlarged view of the front tool part made of sheet steel with the opposite side. Figure 2The stem 1 is rotated approximately 180° around its longitudinal axis. Now the second wing 6 is also visible, forming a right angle with wing 5. The two wings of the steel sheet can each form a right-angled triangle, or one whose lower point is broken, forming a trapezoid, as shown here. The lower end of the steel sheet 4, facing the viewer, then has a blunt end, i.e., it does not taper to a point. The two wings 5 ​​and 6 each form the shape of a trapezoid, each with a lower, larger base a, then a height h, which forms one side d of the trapezoid, and a smaller base c at the top.The other side b of the trapezoid forms an outer edge that runs obliquely to the base lines a and c of the trapezoid and forms an edge that can be used for raking, for example to break up clumps of humus, but also serves as a scraping edge to level a humus bed or to clean an area of ​​humus and stones.

[0010] The Figure 4 Figure 1 shows the garden tool viewed from a slightly oblique front and top view. The sleeve 7 is a pipe section that is slipped over the handle 1 from its front end and secured to the handle 1 with a radial screw 11. Beyond the screw 11, the round rod 3 projects from the sleeve 7 at a right angle, and as can be seen here, the steel sheet 4, bent at a right angle, is placed against this round rod 3 with the inside 9 of its angle 10 and welded to it.

[0011] The Figure 5 a) to c)The illustration shows a garden tool with its handle and three different plow attachments. The uppermost attachment, a), consists of two trapezoidal wings that share a common edge along their height and are at right angles to each other. The wings taper downwards and end in a blunt tip, forming one side of a trapezoid. This type of plow is formed from a single piece of chrome steel sheet. This attachment is ideal for creating a furrow 10 to 20 cm deep, forming a flat, ribbon-like strip of soil at the bottom. Such a furrow is perfect for adding a layer of fertilizer to this flat, strip-like soil. The seeds of the desired crops or vegetables are then sown on this fertilizer layer, lying approximately halfway down the furrow.Finally, using the same garden tool and one long side of the plow, the soil on both sides is pulled or pushed back into the furrow and the top of the furrow is leveled.

[0012] The unclaimed variant b) below in Figure 5The image shows a plow formed by two triangular wings, each forming a right-angled triangle. These two triangles are joined along their longer sides, meaning the plow is made from a single piece of chrome steel sheet. The plow tapers to a point at the bottom. It is excellent for loosening the top layer of humus, for example, in a garden bed, and for removing grass and roots. It is an ideal tool for hoeing between rows of carrots, onions, radishes, etc. It is much faster than using a garden hoe or a spade to turn over the soil. Creating a downward-pointing furrow is just as easy. Such a furrow is particularly suitable for planting potatoes, corn, cabbage, and savoy cabbage.

[0013] The unclaimed variant c) corresponds to that in Figures 10 to 12The design shown is as follows. Here, one wing of the plow is aligned almost in the direction of pull, while the other is angled away from the direction of pull and curved outwards towards the rear on its upper side. It is a very versatile tool. It can be used for hoeing, plowing, smoothing the topsoil of beds, and scraping away soil and stones from hard surfaces such as wooden beams or paving stones. With this plow, a furrow can be created extremely quickly and easily for planting bulbs or sowing seeds. Simply pull the plow through the soil, and the furrow is created in one pass. After planting the bulbs or sowing the seeds, the furrow can be filled in and smoothed with one of the plow's wings. A furrow can also be created very close to the edge of a bed, especially if the bed is bordered by a horizontal wooden beam, as is often the case.In this case, the plow blade, pointing approximately in the direction of travel, is pulled along the wooden beam that serves as a guide. This creates a furrow very close to and along the wooden beam. The curvature of the other plow blade turns the soil displaced by the plow as it moves forward, loosening the soil and promoting aeration of the humus.

[0014] The Figure 6 shows one with the plow after Figure 5a A furrow with a level, strip-shaped layer of soil was created. The plowed soil lies to the left and right of the furrow. The empty furrow was filled with fertilizer to about one-third of its height. Seeds were then scattered on this fertilizer base, and finally, using a garden tool, specifically a plow blade, the soil to the left and right of the furrow was drawn into it, and the furrow was leveled.

[0015] In Figure 7The garden tool is shown in use for breaking up clumps of humus and leveling or smoothing the humus bed. The handle 1 is held in a twisted position so that edge b on the tool points downwards. This edge b can then be used for hoeing or for smoothing along the surface of the bed to level and smooth the humus. The wing 5, or rather its surface, can be used as a plow or scraper.

[0016] The Figure 8 The illustration shows the garden tool in use as a scraper. In the example shown, the edge b is run along a wooden beam 12, which serves here as the boundary of the planting bed, and the wing 5 acts as a plow or scraper, making it very easy to remove all humus and any stones from beam 12 and scrape them away.

[0017] The Figure 9This demonstrates a particularly efficient use of this garden tool, namely as a plow for creating a furrow in a planting bed, for later planting seedlings or bulbs, or for sowing seeds. For this purpose, the garden tool is pulled by its handle 1 and the steel tool at the front end is inserted into the humus and then pulled through the humus. The steel tool acts as a plow, displacing the humus on both sides, creating a V-shaped furrow 13 into which seedlings or bulbs for various plants can then be placed. Finally, the furrow can be filled in again using the same tool as a scraper, as shown in [reference to illustration]. Figure 7 shown.

[0018] The Figure 10Figure 1 shows the garden tool viewed from above, with a special curvature on one wing 14 of the steel sheet 4, in that its upper outer corner is curved outwards to push the soil to the side and turn it over simultaneously when plowing. The opposite wing of the steel sheet, however, is flat, without curvature, and shorter. Figure 11 The figure shows the steel sheet thus shaped, with a curved wing 14 on one side, in its operating position for plowing when it is pulled through the soil in the direction of the arrow shown. The rear upper corner of the wing 14 is curved outwards so that the soil plowed to the side is turned over. Figure 12 The garden tool is shown in use with such a one-sided curved wing 14 of the sheet steel 4, with the associated handle 1. It serves to draw a narrow furrow, which is why only one of the two wings is curved outwards at its upper rear corner. Figure 13It can be seen that the flat wing runs at a shallower angle to the handle than the one with the outwardly curved corner. To guide this steel sheet in the soil as a plow, a bolted-on blade 15 is used, which is guided in its front area by a curve 16 around the front angle 10 of the steel sheet. The blade 15 is screwed to the curved steel wing by means of two screws 17. Figure 14Figure 1 shows this plow, thus formed, in its operating position. The blade 15 cuts deep into the soil like a knife and is pulled through the soil, thereby stabilizing the entire plow. It tapers to a point 18 at the front and its forward curvature is guided around the front angle 10 of the two wings of the steel plate 4. During plowing, the plow, with its blade 15 guiding and stabilizing it, is pulled through the soil, creating a narrow furrow that is then thrown to the side by the curvature of one wing.

[0019] In Figure 14The blade 15, lying on the ground in front of the plow, is shown separately with its sharp leading edge 22. It extends downwards from a blade carrier 20 through a widening, forming a blade similar to a knife blade. The blade carrier 20 has holes 19 for fastening to the lower edge of the plow wing to be fitted with the blade, and the screws are shown next to the blade 15. Instead of screws, this blade carrier can also be attached to the steel plate using bobbin rivets 21 or blind rivets. Number list
