Description

Technical Field

[0001] The present invention relates to a lawnmower belt for suspending a lawnmower and a lawnmower kit having the lawnmower belt. Background Technology

[0002] For example, Patent Document 1 describes a belt worn by a lawnmower user for suspending the lawnmower. The belt described in Patent Document 1 includes: a rope member that wraps around the user's waist and extends along the belt; and a locking member that can move along the rope member. The lawnmower, suspended by the belt and attached to the locking member, is located near the user's right waist. Patent Document 1 proposes a method for supporting the lawnmower solely by the belt, without the need for shoulder straps hanging on the user's shoulders.

[0004] Patent documents

[0005] Patent Document 1: Japanese Patent No. 6642648 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] The belt described in Patent Document 1 is a structure that supports the vertical load of the lawnmower solely by the tightening force of the belt acting in a roughly horizontal direction. Therefore, the load of the lawnmower acts directly and concentrated on one side of the belt (i.e., the user's right waist). The user wearing this belt must bear the concentrated load on their right waist while mowing. Furthermore, it is conceivable that the belt could slip off one side of the lawnmower. Considering these factors, even if this belt structure could free the user from the inconvenience of shoulder straps, it does not alleviate the burden caused by the lawnmower's load, raising questions about its practicality.

[0008] The present invention was made in view of the above circumstances, and its object is to provide a lawnmower belt and lawnmower kit that can eliminate the need for a shoulder strap and reduce the burden on the user.

[0009] Technical solutions for solving the problem

[0010] To achieve the above objectives, the lawnmower strap according to the first aspect of the present invention is a lawnmower strap worn by a user of the lawnmower for suspending the lawnmower, and includes:

[0011] A pelvic pad that is wrapped around the user's pelvic area;

[0012] The main strap is wound around the pelvic liner and fastened to the pelvic region via the pelvic liner;

[0013] A secondary strap, which is fastened to the user's waist;

[0014] Multiple secondary loop straps (Japanese: サブベルトループ), which are disposed in the pelvic liner for the secondary straps to pass through; and

[0015] A suspension unit, located on the pelvic liner, is capable of suspending the lawnmower.

[0016] The pelvic pad is suspended from the secondary straps by the plurality of secondary loops.

[0017] The plurality of secondary loops include a corresponding secondary loop, which is located above the suspension portion at a position corresponding to the suspension portion.

[0018] Alternatively, the suspension unit may include: a left suspension unit located on the user's left leg when the lawnmower belt is worn by the user; and a right suspension unit located on the user's right leg when worn.

[0019] When the lawnmower is suspended on one of the left and right suspension sections, a pad that contacts at least one of the user's knees and thighs can be suspended on the other.

[0020] Alternatively, the left suspension portion may include a first left fastening portion and a second left fastening portion, which are spaced apart from each other along the long side of the pelvic pad and are capable of fastening the suspension component.

[0021] In the wearing state, the first left fastening part is located in front of the second left fastening part relative to the user.

[0022] The right suspension portion includes a first right fastening portion and a second right fastening portion, which are spaced apart from each other along the long side of the pelvic pad and are capable of fastening the suspension component.

[0023] In the wearing state, the first right fastening part is located in front of the second right fastening part relative to the user.

[0024] With the lawnmower suspended from the left suspension unit and the pad suspended from the right suspension unit, the left suspension unit suspends the lawnmower via a hanging member fastened to the first left fastening unit and the second left fastening unit, and the right suspension unit suspends the pad via a hanging member fastened to the first right fastening unit.

[0025] When the lawnmower is suspended from the right suspension part and the pad is suspended from the left suspension part, the right suspension part suspends the lawnmower via a hanging member fastened to the first right fastening part and the second right fastening part, and the left suspension part suspends the pad via a hanging member fastened to the first left fastening part.

[0026] Alternatively, the corresponding secondary loop band may have at least four corresponding to the first left fastening portion, the second left fastening portion, the first right fastening portion, and the second right fastening portion.

[0027] Alternatively, the lawnmower belt may also include multiple main loop belts (Japanese: メインベルトループ) disposed on the pelvic liner and through which the main belt passes.

[0028] The plurality of main loops include a corresponding main loop located below the corresponding secondary loop and at a position corresponding to the corresponding secondary loop.

[0029] To achieve the above objectives, the second aspect of the present invention relates to a lawnmower kit comprising the lawnmower belt, the lawnmower, and a lawnmower handle mounted on the lawnmower, wherein...

[0030] The lawnmower includes: a shaft extending along the user's front-rear direction; a rotating blade located at the front end of the shaft; and a prime mover located at the rear end of the shaft to rotate the rotating blade.

[0031] The lawnmower handle has the following features:

[0032] A rod-shaped portion that intersects the axis and extends in a left-right direction from the user's perspective;

[0033] The left handle, located to the left of the rod-shaped portion as viewed from the user's perspective, is held by the user's left hand; and

[0034] The right handle, located on the right side of the rod-shaped part as viewed from the user's perspective, is held by the user's right hand.

[0035] The rod-shaped portion has a mounting portion that intersects with the shaft and is mounted on the shaft.

[0036] In the first case where the rotating blade of the lawnmower rotates counterclockwise from the user's perspective, the mounted portion is positioned offset to the left of the center of the rod-shaped portion in the left-right direction from the user's perspective, and the portion of the rod-shaped portion to the right of the mounted portion from the user's perspective is positioned as a pushed portion that is pressed by the user's leg.

[0037] In the second case where the rotating blade of the lawnmower rotates clockwise from the user's perspective, the mounted portion is positioned offset to the right from the center of the rod-shaped portion in the left-right direction from the user's perspective, and the portion of the rod-shaped portion to the left of the mounted portion from the user's perspective is positioned as a pushed portion that is pressed by the user's leg.

[0038] The lawnmower handle positions the lawnmower to the user's left in the first case and to the user's right in the second case.

[0049] An embodiment of the present invention will be described with reference to the accompanying drawings.

[0050] like Figure 1 As shown, the lawnmower kit 1 includes a lawnmower 2, a lawnmower belt 3, a lawnmower handle 4, a buffer plate 5, and a pad 6. Additionally, as... Figure 5 As shown in (a) and (b), the lawnmower kit 1 also includes accessory 7.

[0051] (Lawnmower 2)

[0052] The lawnmower 2 includes a shaft 20, a rotary blade 21, a prime mover 22, a throttle valve 23, and a fly scattering guard 24.

[0053] User 8 operates lawnmower 2 to cut grass, small trees, etc. Figure 1 and Figure 4 In the diagram, for user 8, the directions are shown as follows: front (Fd), back (Bd), left (Ld), right (Rd), top (Ud), and bottom (Dd) (described later). Figure 8 (The same applies). Unless otherwise specified, the directions forward, backward, left, right, up, and down used in the following description refer to directions from the user's perspective (8).

[0054] Shaft 20 extends along the front-rear direction of the user 8 of the lawnmower 2. Shaft 20 is a tubular component, and inside it is a rotating shaft (not shown) that rotates the rotating blade 21 in response to the power of the prime mover 22. A position closer to the prime mover 22 than the center of shaft 20 in the long side direction is set as the grip mounting position 20a for mounting the lawnmower handle 4. Shaft 20 has a suspended portion 20b, which is suspended from the lawnmower belt 3 in a manner described later, at a portion closer to the prime mover 22 than the grip mounting position 20a. The suspended portion 20b is, for example, an annular component fixed to shaft 20.

[0055] The rotating blade 21 is located at the front end of the shaft 20. The rotating blade 21 is a circular saw formed in the shape of a disc, such as a saw blade. As observed by the user 8, the rotating blade 21 in this embodiment rotates counterclockwise. Hereinafter, objects that can be cut by the rotating blade 21 will be referred to as "grass, etc." Grass, etc. is not limited to grass, but includes small trees, branches, etc.

[0056] The prime mover 22 is located at the rear end of the shaft 20 and causes the rotating cutter 21 to rotate. The prime mover 22 is composed of an engine or motor and causes the rotating cutter 21 to rotate via a rotating shaft provided inside the shaft 20.

[0057] Throttle valve 23, used by user 8 to operate prime mover 22, is mounted on lawnmower handle 4. In this embodiment, throttle valve 23 is mounted on the left handle 4L of lawnmower handle 4 (described later). Throttle valve 23 is electrically connected to prime mover 22 via throttle valve wire (not shown). User 8 operates the rotation of rotary blade 21 via prime mover 22 by gripping throttle valve 23.

[0058] The scattering guard 24 is a component used to protect the user 8 from the scattering of grass and other materials cut by the rotating blade 21. The scattering guard 24 is detachable relative to the shaft 20 and is installed near the rotating blade 21.

[0059] (Lawnmower with belt 3)

[0060] The lawnmower belt 3 is a structure used to suspend the lawnmower 2, and is worn by the user 8. For example... Figures 1-3 As shown, the lawnmower belt 3 includes a pelvic pad 30, a main belt 31, an auxiliary belt 32, a suspension part 33, multiple auxiliary loop belts 34, and multiple main loop belts 35.

[0061] The pelvic pad 30 is a strip of cushioning material wrapped around the pelvic area of ​​user 8. This pelvic area is roughly the same as the buttocks of user 8.

[0062] The main strap 31 is wound around the pelvic pad 30 and secured to the pelvic area of ​​the user 8 via the pelvic pad 30. For example... Figure 2 As shown, the main strap 31 passes through a plurality of main loop straps 35 provided on the pelvic pad 30. The width of the main strap 31 is narrower than the width of the pelvic pad 30. A fastener 31a for tightening the main strap 31 to the pelvic part of the user 8 is provided at one end of the main strap 31 in the long side direction. The fastener 31a can be a well-known buckle, Velcro, etc. It should be noted that an adjuster (not shown) for adjusting the length of the main strap 31 can also be provided on the main strap 31. The user 8 installs the pelvic pad 30 to their pelvic part by fastening the main strap 31 by the fastener 31a. With the pelvic pad 30, the tightening force of the main strap 31 is distributed to the pelvic part of the user 8, thus reducing the burden on the user 8.

[0063] The secondary strap 32 is fastened to the user's waist. For example... Figure 2 As shown, the secondary strap 32 passes through a plurality of secondary loop straps 34 facing upwards toward the pelvic pad 30. The width of the secondary strap 32 is set to be narrower than the width of the main strap 31 in this embodiment, but is not limited thereto, and its width can be arbitrarily set. A fastener 32a is provided at one end of the secondary strap 32 along its long side for tightening the secondary strap 32 around the waist of the user 8. The fastener 32a can be a well-known buckle, Velcro, etc. It should be noted that an adjuster (not shown) for adjusting the length of the secondary strap 32 can also be provided. The user 8 secures the secondary strap 32 to their waist using the fastener 32a.

[0064] The suspension part 33 is a portion provided on the pelvic pad 30 that is capable of suspending the lawnmower 2. The suspension part 33 includes a left suspension part 331 located on the left leg of the user 8 when the lawnmower strap 3 is worn on the user 8 (hereinafter referred to as the wearing state), and a right suspension part 332 located on the right leg of the user 8 when the lawnmower strap 3 is worn on the user 8.

[0065] The left suspension portion 331 includes a first left fastening portion 331a and a second left fastening portion 331b, which can fasten a suspension member, for example, made of a sling. Hereinafter, the suspension member that can be fastened to the left suspension portion 331 will be referred to as the left suspension member S1. The first left fastening portion 331a and the second left fastening portion 331b are arranged spaced apart from each other in the long side direction of the pelvic pad 30. In the wearing state, the first left fastening portion 331a is located in front of the user 8, more so than the second left fastening portion 331b. The first left fastening portion 331a and the second left fastening portion 331b are each made of, for example, a D-shaped loop, which passes through and is supported by a support loop 36, which is provided at the lower end of the pelvic pad 30.

[0066] The right suspension portion 331 includes a first right fastening portion 331a and a second right fastening portion 331b, which can fasten a suspension member, for example, made of a sling. Hereinafter, the suspension member that can be fastened to the right suspension portion 332 will be referred to as the right suspension member S2. The first right fastening portion 332a and the second right fastening portion 332b are arranged spaced apart from each other in the long side direction of the pelvic pad 30. In the wearing state, the first right fastening portion 332a is located in front of the second right fastening portion 332b relative to the user 8. The first right fastening portion 332a and the second right fastening portion 332b are each made of, for example, a D-shaped loop, which passes through and is supported by a support loop 36, which is provided at the lower end of the pelvic pad 30.

[0067] It should be noted that the lengths of both the left hanging component S1 and the right hanging component S2 can be adjusted using an adjuster (not shown). Furthermore, both the left hanging component S1 and the right hanging component S2 can be any material, not limited to a sling, as long as it can suspend an object. Both the left hanging component S1 and the right hanging component S2 can be chains, lines, ropes, etc.

[0068] In this embodiment, where the rotating blade 21 rotates counterclockwise as observed by user 8, the lawnmower 2 is suspended from the left suspension section 331. Figure 2 As shown, the left hanging component S1 is secured to the first left fastening part 331a and the second left fastening part 331b of the left suspension part 331. The lawnmower 2 is suspended from the left suspension part 331 via the left hanging component S1. Specifically, the left hanging component S1, which is secured to the first left fastening part 331a and the second left fastening part 331b respectively, is V-shaped, as shown... Figure 1 As shown, its lower end is connected to the buffer plate 5.

[0069] like Figure 1As shown, the buffer plate 5, connected to the left hanging member S1, is used between the side of the user 8's left thigh and the shaft 20 of the lawnmower 2. The buffer plate 5 prevents the shaft 20 from directly contacting the user 8's leg, reducing the burden on the user 8 during mowing. The buffer plate 5 is provided with a hook 50 that hooks onto the suspended portion 20b of the shaft 20. The hook 50 can be, for example, a hook, a quick-release mechanism, etc.; any component can be used as long as it can hook onto the suspended portion 20b. As described above, in this embodiment, the left hanging portion 331 suspends the lawnmower 2 via the left hanging member S1 and the buffer plate 5.

[0070] In this embodiment, when the rotating blade 21 rotates counterclockwise as observed by user 8, the pad 6 is suspended from the right suspension portion 332. Figure 2 As shown, a right suspension member S2 is attached to the first right fastening part 332a of the right suspension part 332. The right suspension part 332 suspends the pad 6 via the right suspension member S2. Specifically, as... Figure 1 As shown, the lower end of the right hanging component S2, which is fastened to the first right fastening part 332a, is connected to the pad 6.

[0071] like Figure 1 As shown, the pad 6, connected to the right hanging component S2, is used in a manner positioned between the front surface of the user 8's right thigh and the lawnmower handle 4. The pad 6 prevents the lawnmower handle 4 from directly contacting the user 8's leg, reducing the burden on the user 8 during mowing operations. Furthermore, when pushing out the lawnmower handle 4 with the right leg as described later, the pad 6 can effectively apply force to the lawnmower handle 4. The pad 6 is, for example, a sheet material formed of resin and bent to fit against the user 8's thigh.

[0072] It should be noted that the pad 6 can be shaped to contact at least one of the user 8's knee and thigh. Additionally, the pad 6 can be formed in a grid pattern, a mesh pattern, or have lightweight perforations to achieve weight reduction.

[0073] like Figure 2 As shown, in this embodiment, the secondary loops 34 are respectively disposed above the first left fastening portion 331a, the second left fastening portion 331b, the first right fastening portion 332a, and the second right fastening portion 332b. That is, four secondary loops 34 are provided for the pelvic pad 30 of this embodiment.

[0074] like Figure 2 As shown, five main loop straps 35 of this embodiment are provided on the pelvic pad 30. Among them, as... Figure 2As shown, four main loops 35 are respectively disposed above the first left fastening part 331a, the second left fastening part 331b, the first right fastening part 332a, and the second right fastening part 332b. In addition, the remaining main loop 35 is disposed in the center of the pelvic pad 30 along the long side, and is located near the spine of the user 8 when worn.

[0075] In this embodiment where the lawnmower 2 is suspended from the left suspension section 331, the two secondary loops 34 located above the left suspension section 331 and corresponding to the left suspension section 331 (i.e., the secondary loop 34 corresponding to the first left fastening section 331a and the secondary loop 34 corresponding to the second left fastening section 331b) function as corresponding secondary loops. Furthermore, the main loop 35 corresponding to the first left fastening section 331a and the main loop 35 corresponding to the second left fastening section 331b function as corresponding main loops located below the corresponding secondary loops and corresponding to those main loops.

[0076] In this embodiment, the support loop 36, main loop 35, and auxiliary loop 34, which are arranged along the short side of the pelvic pad 30 corresponding to the first left fastening part 331a, are integrally formed from a synthetic fiber belt. Specifically, the support loop 36, main loop 35, and auxiliary loop 34, which are arranged corresponding to the first left fastening part 331a, are configured to perform their respective functions by sewing this belt to the pelvic pad 30. It should be noted that the support loop 36, main loop 35, and auxiliary loop 34, which are arranged corresponding to the second left fastening part 331b, the first right fastening part 332a, and the second right fastening part 332b, are also integrally formed from a synthetic fiber belt. As a result, the number of parts can be reduced, manufacturing can be simplified, and the function of the lawnmower belt 3 described later can be effectively performed. It should be noted that, when worn, a main loop band 35 located near the user's spine is constructed by sewing a synthetic fiber band body to the pelvic pad 30.

[0077] Next, refer to Figure 3 The effect of belt 3 on the lawnmower constructed as described above will be explained.

[0078] (Lawnmower with effect 3)

[0079] Figure 3This is a schematic cross-sectional view showing the left suspension section 331 of the lawnmower belt 3 cut along its short side. The lawnmower 2 is suspended from the left suspension section 331, whereby the load Fb of the lawnmower 2 acts downwards on the pelvic pad 30. Furthermore, when the user 8 tightens the main belt 31 around their pelvis, the tightening force Ft generated by the main belt 31 acts on the pelvic pad 30 in a generally horizontal direction. Additionally, when the user 8 tightens the auxiliary belt 32 around their waist, the pelvic pad 30 is suspended from the auxiliary belt 32 by the auxiliary loop belt 34. Thus, the tension Fs generated by the auxiliary loop belt 34 acts upwards on the pelvic pad 30.

[0080] Considering the above, the pelvic pad 30 can counteract (support) the downward-acting load Fb by utilizing the combined vector of the tightening force Ft and the tension Fs. Through this action, the lawnmower belt 3 can disperse the force acting on the user 8 via the pelvic pad 30, thereby reducing the burden on the user 8. If it were possible to prevent the main belt 31 from shifting downward and support the load Fb solely through the tightening force Ft generated by the main belt 31, the tightening force Ft would need to be very large to create the upper component of the force vector, which is impractical. However, according to the lawnmower belt 3 of this embodiment, by creating a state in which the pelvic pad 30 is suspended from the auxiliary belt 32, the burden on the user 8 can be reduced as described above.

[0081] Furthermore, the secondary loop 34 is located above the left suspension portion 331 on which the lawnmower 2 is suspended. This secondary loop 34 functions as a corresponding secondary loop to the left suspension portion 331. By using the corresponding secondary loop, the slippage of the pelvic pad 30 at the location where the lawnmower 2 load Fb is applied (in this embodiment, the left side of the user 8) is prevented.

[0082] It should be noted that, in practice, the user 8 performs mowing operations while rotating the lawnmower 2 in a circular arc shape from side to side. Therefore, torsional force acts on the pelvic pad 30. In the lawnmower belt 3 of this embodiment, the auxiliary loop belts 34 are spaced apart along the long side direction of the pelvic pad 30 (i.e., circumferentially around the pelvic part of the user 8 when worn). Therefore, the tension Fs acting on the pelvic pad 30 via the multiple auxiliary loop belts 34 acts three-dimensionally. As a result, the load Fb applied to the user 8 via the pelvic pad 30 by the lawnmower 2 can be stably supported by a three-dimensional vector force.

[0083] Furthermore, based on the lawnmower strap 3 described above, the shoulder strap that hangs on the user 8's shoulder can be omitted, and the lawnmower 2 can be stably suspended. Because the shoulder strap can be omitted, the user 8's upper body can be freed up, while ensuring upper body mobility and breathability. As a result, the burden on the user 8 can be reduced.

[0084] (Differences from safety belts used in electrical engineering)

[0085] Here, it should be made clear in advance that, as a structure that is similar to the lawnmower belt 3 of this embodiment, there is a safety belt used by electrical engineers when working on poles, but the structure and function of the safety belt are completely different from those of the lawnmower belt 3.

[0086] The safety belt includes a padding that wraps around the pelvis of the worker on the pole, and a safety belt wrapped around the padding. Furthermore, the safety belt is configured to connect with an auxiliary belt wrapped around the waist of the worker on the pole. This auxiliary belt suspends the safety belt to prevent the worker from slipping off and falling, and does not suspend the padding. In this embodiment, the lawnmower belt 3 utilizes an auxiliary loop belt 34 through which the auxiliary belt 32 passes, suspending the pelvic padding 30, which bears the load Fb of the lawnmower 2, instead of the main belt 31. Therefore, its structure and function are completely different from the safety belts used by electrical engineers.

[0087] Furthermore, the auxiliary belt used to suspend the safety belt, which ensures the operator's posture while working on the pole and also functions as a chair, needs to suspend the safety belt evenly in all directions. On the other hand, in the lawnmower belt 3, the auxiliary belt 32 does not necessarily suspend the pelvic pad 30 evenly in all directions. The lawnmower belt 3 can be a structure in which the pelvic pad 30 is suspended by the auxiliary belt 32 at least via an auxiliary loop belt 34 provided at a position corresponding to the suspension part 33 that can suspend the lawnmower 2. There is also a significant difference between the two in this respect.

[0088] (Lawnmower handle 4)

[0089] like Figure 1 and Figure 4 As shown, the lawnmower handle 4 has a rod-shaped part 40, a left-curved part 410, a left-bent part 411, a right-curved part 420, and a right-bent part 421.

[0090] The rod-shaped portion 40, the left-bent portion 410, the left-bent portion 411, the right-bent portion 420, and the right-bent portion 421 are integrally formed, for example, by a tube made of stainless steel, aluminum, or the like.

[0091] The rod-shaped portion 40 is the part that intersects the shaft 20 of the lawnmower 2 and extends in the left-right direction when viewed from the user 8. In this embodiment, the rod-shaped portion 40 extends in a straight line. The rod-shaped portion 40 has a mounting portion 40a that is mounted on the shaft 20 as the part that intersects the shaft 20. Specifically, the mounting portion 40a is mounted on the shaft 20 by a connecting member 40b. As the connecting member 40b, for example, a clamp for pipe connection can be used, but it is not limited to this. Any structure can be used as long as the rod-shaped portion 40 can be connected to the shaft 20. In this embodiment, the lawnmower handle 4 is mounted on the shaft 20 in a manner where the rod-shaped portion 40 is orthogonal to the shaft 20. It should be noted that the rod-shaped portion 40 and the shaft 20 do not necessarily have to be orthogonal. As long as it does not impede the ease of operation of the lawnmower 2 for the user 8, they can be tilted relatively (for example, a few degrees) relative to the orthogonal relationship.

[0092] The left-curved portion 410 is a portion that extends upward toward the user 8 while being continuous with the left end of the rod-shaped portion 40 and curving upward toward the user 8 when viewed from the user 8. Specifically, the left-curved portion 410 has a shape that extends diagonally upward and backward toward the user 8 while curving from the left end of the rod-shaped portion 40.

[0093] The left bend 411 is a portion that is continuous with the upper end of the left bend 410 and extends towards the front of the user 8. A left handle 4L is provided in the left bend 411 for the user 8 to hold with their left hand.

[0094] The left handle 4L is, for example, a component made of rubber, sponge, or other resin materials that is installed on the upper part of the left bend 411. It should be noted that the left handle 4L is not limited to a component installed on the left bend 411, but may also be a part of the left bend 411 for the user 8 to hold with their left hand.

[0095] The right-bending portion 420 is a portion that, when viewed from the user 8, is continuous with the right end of the rod-shaped portion 40 and extends upward toward the user 8 while bending. Specifically, the right-bending portion 420 has a shape that bends from the right end of the rod-shaped portion 40 and extends further to the right and diagonally upward and backward toward the user 8.

[0096] The right bend portion 421 is a portion that is continuous with the upper end of the right bend portion 420 and extends towards the front of the user 8. A right handle 4R for the user 8 to hold with their right hand is provided in the right bend portion 421.

[0097] The right handle 4R is, for example, a component made of rubber, sponge, or other resin materials that is installed on the upper part of the right bend 421. It should be noted that the right handle 4R is not limited to a component installed on the right bend 421, but may also be a part of the right bend 411 for the user 8 to hold with their right hand.

[0098] In this embodiment, where the rotating blade 21 rotates counterclockwise when viewed from the user 8's perspective, the mounting portion 40a is positioned offset from the center-to-left bending portion 410 of the rod-shaped portion 40 in the left-right direction. Furthermore, in the lawnmower handle 4 where the mounting portion 40a is mounted at the handle mounting position 20a of the shaft 20, the portion between the mounting portion 40a of the rod-shaped portion 40 and the right-bending portion 420 is designated as a "pressed portion" that is pushed by the user 8's leg. Moreover, in this embodiment, the lawnmower handle 4 positions the lawnmower 2 to the left of the user 8.

[0099] With the lawnmower 2 properly suspended on the lawnmower belt 3, such as Figure 1 As shown, the portion between the mounting portion 40a and the right-bent portion 420 of the rod-shaped portion 40 (the aforementioned pushed portion) is located in front of the user 8's legs. This pushed portion is preferably set at the height of the user 8's knees or thighs.

[0100] When the handle 4 of the lawnmower is configured as described above, the left bend 410 is positioned along and spaced apart from the left thigh of the user 8. Furthermore, the left bend 411 is positioned in a forward-leaning posture from the upper end of the left bend 410. Similarly, the right bend 420 is positioned along and spaced apart from the right thigh of the user 8. Furthermore, the right bend 421 is positioned in a forward-leaning posture from the upper end of the right bend 420.

[0101] In addition, the left side portion (i.e., the left bend portion 410 and the left flex portion 411) and the right side portion (i.e., the right bend portion 420 and the right flex portion 421) of the lawnmower handle 4 are formed such that the interval between them (the interval in the left-right direction) increases slightly as they move away from the rod-shaped portion 40.

[0102] The lawnmower handle 4 formed as described above allows the user 8 to grip the left handle 4L and right handle 4R with (i) slightly opening the left and right armpits, (ii) letting the upper arms hang naturally, and (iii) slightly bending the elbows. Thus, the user 8 can grip the lawnmower handle 4 in a relaxed and stress-free posture.

[0103] Here, refer to Figure 7 The method of using the lawnmower 9 involved in the existing example will be explained.

[0104] (Example of how to use lawnmower 9)

[0105] In the conventional example, when the rotating blade 91 of the lawnmower 9 rotates counterclockwise as viewed from the user 8, the lawnmower 9 is suspended to the right of the user 8 using a well-known strap worn on the user 8. The user 8 performs mowing operations while rotating the lawnmower 9 and the handle 94 mounted on the shaft 90 of the lawnmower 9 around the suspension position P of the lawnmower 9. At this time, the user 8 uses the rotating blade 91 to cut grass and the like while rotating the lawnmower 9 in an arc from right to left. If the lawnmower 9 is moved to the left while mowing until the desired position is reached, then the lawnmower 9 is rotated in the opposite direction from left to right in an arc. The user 8 performs mowing operations by repeatedly rotating the lawnmower 9 in an arc from right to left and from left to right around the suspension position P, gradually moving forward.

[0106] In the existing example, user 8 primarily rotates the lawnmower 9 from right to left by pushing the right handle 94R of the handle 94 with the right hand. In detail, although user 8 also uses the force of pulling the left handle 94L with the left hand, the force of pushing the shaft 90 with the waist, and the force of pushing the handle 94 with the legs, the fact remains that the force pushed by the right hand is decisive in rotating the lawnmower 9 from right to left in the structure of the handle 94 and the lawnmower 9 involved in the existing example.

[0107] Here, the force exerted by pushing the right handle 94R with the right hand is defined as f, and the length along the handle 94 from the suspension position P to the right handle 94R is defined as l. Thus, the magnitude of the torque n of the force that causes the lawnmower 9 to rotate from right to left is approximately n = f × l. In the existing examples of the handle 94 and lawnmower 9, since the lawnmower 9 is suspended on the right side of the user 8, the length l cannot be increased structurally. In particular, when the lawnmower 9 rotates from right to left, the reaction force acts in the opposite direction via the rotating blade 91 because of the action of cutting grass with the rotating blade 91. Considering these factors, it is clear that the force exerted by pushing the right handle 94R with the right hand needs to be increased. Thus, in the existing examples of the handle 94 and lawnmower 9, the burden on the user 8's hand and arm is very large when the lawnmower 9 rotates from right to left.

[0108] It should be noted that when the lawnmower 9 is rotated from left to right, the reaction force from the rotating blades 91 cutting grass is less compared to when the lawnmower 9 is rotated from right to left. However, the force exerted by the left handle 94L by pushing the handle 94 with the left hand is still decisive, so the burden on the user's hand and arm remains greater.

[0109] Next, refer to Figure 6 While comparing with existing examples, the effects of the lawnmower grip 4 of this embodiment and its usage method are explained.

[0110] (The effect of using grip 4 on a lawnmower)

[0111] In this embodiment, where the rotating blade 21 of the lawnmower 2 rotates counterclockwise as observed by the user 8, the lawnmower 2 is suspended to the left of the user 8 using a lawnmower strap 3 worn on the user 8. The user 8 performs mowing operations while rotating the lawnmower 2 and the lawnmower handle 4 in an arc around the suspension position O of the lawnmower 2. At this time, the user 8 uses the rotating blade 21 to cut grass and other vegetation as the lawnmower 2 rotates from right to left. If the lawnmower 2 is rotated to the left while mowing until the desired position is reached, the lawnmower 2 is rotated from left to right in the opposite direction next time. The user 8 performs mowing operations by repeatedly rotating the lawnmower 2 in an arc around the suspension position O from right to left and from left to right.

[0112] As user 8 steps forward with their right leg, they push the pressed portion of the lawnmower handle 4 using their right knee or thigh. This causes the lawnmower 2 and the lawnmower handle 4 to rotate from right to left around the suspension position O. During this rotation, the rotating blade 21 cuts grass and other vegetation. At this time, because a pad 6 is provided on user 8's right leg, force can be effectively applied to the pressed portion of the lawnmower handle 4 via the pad 6.

[0113] Without the pad 6, the rod-shaped portion 40 (the pushed portion) of the lawnmower handle 4 sinks into the user 8's right leg, thus dispersing the force that pushes the user 8's right leg. On the other hand, with the pad 6 present, the rod-shaped portion 40 (the pushed portion) of the lawnmower handle 4 is prevented from sinking into the user 8's right leg, thus effectively transmitting the force that pushes the right leg to the rod-shaped portion 40 and reducing the burden on the user 8's right leg.

[0114] Conversely, when the lawnmower 2 and the lawnmower handle 4 are turned from left to right, the user 8, while taking a step forward with their left leg, uses their left knee or thigh to push the pushed portion of the lawnmower handle 4 (specifically, the left side of the rod-shaped portion 40). Thus, the lawnmower 2 and the lawnmower handle 4 rotate from left to right around the suspension position O.

[0115] As described above, based on the lawnmower handle 4, the user 8 can rotate the lawnmower 2 and the lawnmower handle 4 from right to left and from left to right simply by alternately stepping forward with the right and left legs. At this time, the user 8 only needs to lightly grip the right handle 4R and the left handle 4L of the lawnmower handle 4 with both hands, requiring almost no arm force to rotate the lawnmower 2 and the lawnmower handle 4. That is, in this embodiment, the force of pushing the lawnmower handle 4 outward with the right leg is mainly used to rotate the entire lawnmower 2 from right to left.

[0116] Here, the force exerted by the right leg to push off the lawnmower handle 4 is defined as F, and the length along the lawnmower handle 4 from the suspension position O to the position where the lawnmower handle 4 is pushed by the right leg (specifically, the position pushed by the pad 6) is defined as L. Thus, the magnitude N of the torque of the force that causes the lawnmower 2 to rotate from right to left is approximately N = F × L. In the lawnmower handle 4 and lawnmower 2 according to this embodiment, since the lawnmower 2 is suspended on the left side of the user 8, the length L can be increased structurally. In particular, when the lawnmower 2 rotates from right to left, since it is in the action of cutting grass with the rotating blade 21, the reaction force acts in the opposite direction via the rotating blade 21. However, according to the lawnmower handle 4, a larger length L can be ensured. Furthermore, it is extremely easy to ensure that the force F exerted by the right leg is much greater than that exerted by the right hand. The usefulness of the function and effect of this embodiment can be demonstrated by comparison. Figure 6 as well as Figure 7 And it is easy to master.

[0117] Considering the above, it can be seen that, according to the structure of the lawnmower handle 4 according to this embodiment, the burden on the user 8 can be greatly reduced when the lawnmower 2 is rotated from right to left. It should be noted that when the lawnmower 2 is rotated from left to right, the user 8 only needs to take a step forward with his left leg, so the burden when rotating the lawnmower 2 from left to right is very small.

[0118] Furthermore, the lawnmower handle 4, as described above, allows the user 8 to grip the right handle 4R and left handle 4L in a posture that does not put pressure on the body. The pushed portion is pushed by the user 8's alternating forward movement of stepping with the right and left legs, thereby causing the lawnmower handle 4 to rotate alternately to the left and right around the suspension position O. Therefore, when the user 8 rotates the lawnmower handle 4 and the lawnmower 2, they can gently grip the right handle 4R and left handle 4L with both hands, and only need to make minor adjustments to the position of the lawnmower handle 4 and the lawnmower 2 through the right handle 4R and left handle 4L.

[0119] (Accessory 7)

[0120] Figure 5The accessory 7 shown in (a) and (b) is a component that can be installed on the back side 21b of the rotating blade 21 as viewed from the user 8. Accessory 7 is fixed to the rotor that rotates the rotating blade 21 by a fixing member 7a consisting of bolts, nuts, etc. Thus, accessory 7 rotates together with the rotating blade 21 about the rotation axis 21a of the rotating blade 21. Accessory 7 is used in contact with the ground during cutting operations. With accessory 7, the user 8 can perform cutting operations while ensuring the distance between the rotating blade 21 and the ground, thus reducing the burden on the user 8.

[0121] Accessory 7 has a curved surface 70 that bulges away from the rotating blade 21, and a side surface 71 located between the curved surface 70 and the rotating blade 21. The curved surface 70 and the side surface 71 are formed as a rotating body centered on the rotation axis 21a (the shape formed when rotating one revolution around the rotation axis 21a). Figure 5 As shown in (a), the curved surface 70 is the part that contacts the ground.

[0122] The side portion 71 is the part of the fitting 7 that corresponds to the side of a cylinder centered on the axis of rotation 21a. In this embodiment, the side portion 71 is perpendicular to the back surface 21b of the rotating blade 21. A plurality of protrusions 72 are provided on the side portion 71, protruding along the back surface 21b of the rotating blade 21.

[0123] In this embodiment, the protrusions 72 are provided in pairs, protruding radially about the axis of rotation 21a and in opposite directions. That is, in this embodiment, two protrusions 72 are provided. The two protrusions 72 protrude substantially parallel to (or exactly parallel to) the back surface 21b. It should be noted that the shape, length, and size of the protrusions 72 are not limited as long as they can perform the functions described below. For example, the protrusions 72 can be cylindrical or conical.

[0124] The effects of accessory 7 in this embodiment will be explained below.

[0125] (Effect of accessory 7)

[0126] Foreword Figure 7 The lawnmower 9 described in the existing example is used by being suspended near the right waist of the user 8. On the other hand, as... Figure 1 As shown, the lawnmower 2 of this embodiment is used by suspending itself from the thigh to the knee of the user 8's left leg. Thus, by using the lawnmower 2 of this embodiment at a lower position than in conventional examples, it can be used with a smaller angle between the ground and the axis 20 than before.

[0127] When using the lawnmower 2 according to this embodiment as described above, such as Figure 5As shown in (a), the rotating blade 21 is tilted with its front end positioned higher than its rear end. Thus, as the accessory 7 rotates together with the rotating blade 21, the rear protrusion 72 (the protrusion 72 closer to the user 8) of the pair of protrusions 72 provided on the side portion 71 of the accessory 7 approaches the ground, while the front protrusion 72 (the protrusion 72 further away from the user 8) moves away from the ground.

[0128] At this time, because the rear protrusion 72 touches the grass, a reaction force acts on the rear protrusion 72 in the opposite direction to the counterclockwise rotating blade 21. Therefore, as... Figure 5 As shown in (b), the force Fr directed to the left acts on the shaft 20 via the rear protrusion 72. On the other hand, the front protrusion 72 does not touch grass or the like, or the proportion of contact with grass or the like is very small compared to the rear protrusion 72. Therefore, the reaction force acting on the front protrusion 72 can be ignored.

[0129] As described above, the accessory 7, which has a pair of protrusions 72, transmits a force Fr toward the left to the shaft 20 sequentially as it rotates together with the rotating blade 21. That is, through the action of the accessory 7 rotating together with the rotating blade 21, the lawnmower 2 naturally tends to turn to the left. This reduces the force required by the user 8 during mowing operations to turn the lawnmower 2 and the lawnmower handle 4 from right to left. Thus, the lawnmower kit 1 according to this embodiment can also reduce the burden on the user through the accessory 7.

[0130] It should be noted that the present invention is not limited to the above embodiments and drawings. Modifications (including the deletion of constituent elements) can be appropriately applied without altering the spirit of the invention.

[0131] (Modified Example)

[0132] In the above embodiments, an example is shown where the rotating blade 21 of the lawnmower 2 rotates counterclockwise, but as... Figure 8 As shown, the lawnmower kit 1 can also be used when the rotary blade 21 is rotated clockwise. In this case, refer to... Figure 8 It can be seen that lawnmower kit 1 can... Figure 1 The lawnmower handle 4 is used in a reversed left-right configuration. Specifically, when the rotary blade 21 rotates clockwise, the mounting portion 40a of the lawnmower handle 4 is positioned offset from the center-to-right bend 420 of the rod-shaped portion 40 in the left-right direction. Furthermore, in the lawnmower handle 4, the portion between the mounting portion 40a of the rod-shaped portion 40 and the left-bend 410 is configured as a "pressed portion" that is pushed by the user 8's leg. In this modified example, the lawnmower handle 4 positions the lawnmower 2 to the right of the user 8.

[0133] The method of using the modified lawnmower kit 1 is the opposite of the above embodiment, considering the left-right relationship. That is, the user 8 uses the rotating blade 21 to cut grass and the like while rotating the lawnmower 2 as a whole from left to right. The user 8 performs the mowing operation by repeatedly rotating the lawnmower 2 in an arc shape from left to right and from right to left.

[0134] In a modified example where the rotary blade 21 rotates clockwise, the lawnmower 2 is suspended from the right suspension portion 332 of the lawnmower belt 3. In this modified example, the right suspension portion 332 suspends the lawnmower 2 via the right hanging member S2 and the buffer plate 5. In another modified example, the pad 6 is suspended from the left suspension portion 331. The left suspension portion 331 suspends the pad 6 via the left hanging member S1. Figure 8 As shown, the pad 6, which is connected to the left hanging part S1, is used between the front surface of the user's left thigh and the lawnmower handle 4. Thus, when the lawnmower handle 4 is pushed out by the left leg, the pad 6 can effectively apply force to the lawnmower handle 4.

[0135] As in this modified example, when the lawnmower 2 is suspended from the right suspension section 332, the two secondary loops 34 located above the right suspension section 332 and corresponding to the right suspension section 332 (i.e., the secondary loop 34 corresponding to the first right fastening section 332a and the secondary loop 34 corresponding to the second right fastening section 332b) function as corresponding secondary loops. In this case, the main loop 35 corresponding to the first right fastening section 332a and the main loop 35 corresponding to the second right fastening section 332b function as corresponding main loops located below the corresponding secondary loops and corresponding to the corresponding loops.

[0136] (Other variations)

[0137] The shape and structure of the lawnmower belt 3 can be arbitrarily changed as long as it does not impede its function. For example, the number of the secondary loop belt 34, main loop belt 35, and support loop belt 36 provided on the pelvic pad 30 is not limited to the examples above and can be arbitrarily changed. For example, the positions corresponding to the two secondary loop belts 34 and two main loop belts 35 corresponding to the left suspension part 331 can be changed to one secondary loop belt 34 and one main loop belt 35 that are wider than in the above embodiment. The same applies to the position corresponding to the right suspension part 332. In addition, the lawnmower 2 can be suspended on the lawnmower belt 3 via one left hanging member S1 or one right hanging member S2 that are wider than in the above embodiment.

[0138] The shape and structure of the lawnmower handle 4 can be arbitrarily changed as long as it does not impede its function. For example, the rod-shaped portion 40 does not have to be entirely straight; it can be partially curved. Furthermore, the shapes of the lawnmower handle 4 extending from the rod-shaped portion 40 to the left handle 4L and right handle 4R respectively can be arbitrarily changed as long as they do not interfere with the usage method described above. Additionally, a component replacing the pad 6 can be directly provided in the pressing portion of the lawnmower handle 4. This component can be a cushioning material or the like provided in the pressing portion.

[0139] The lawnmower belt 3 can not only suspend the lawnmower 2 with the lawnmower handle 4 as described above installed, but also suspend the lawnmower with the reference installed. Figure 7 The lawnmower 9 with handle 94 described in the existing example is suspended. In this case, the lawnmower 9 can be suspended from the right suspension part 332 of the lawnmower belt 3 via the right suspension member S2.

[0140] The lawnmower 2 with the above-described handle 4 installed can also be used by hanging it on a belt other than the lawnmower belt 3, which omits the shoulder strap. For example, the lawnmower 2 with the handle 4 installed can also be used by hanging it on a conventional lawnmower hanging belt, such as a belt with a shoulder strap that is hung on the user's shoulder.

[0141] The shape and structure of accessory 7 can be arbitrarily changed as long as it does not impede its function. For example, more than three protrusions 72 may be provided on the side portion 71 of accessory 7. From the viewpoint of assisting the user 8 in rotating the lawnmower 2, it is preferable that the plurality of protrusions 72 provided on the side portion 71 include a pair of protrusions 72 that protrude in opposite directions. In addition, the plurality of protrusions 72 may also be evenly arranged in a circumferential direction centered on the axis of rotation 21a. However, even if only one protrusion 72 is provided on the side portion 71, it can still assist the user 8 in rotating the lawnmower 2 to a certain extent. In addition, the side portion 71 may not be perpendicular to the back surface 21b of the rotating blade 21, or it may be inclined relative to the back surface 21b.

[0142] In the above description, well-known technical matters have been omitted for ease of understanding of the present invention.

[0143] This invention can be implemented and modified in various ways without departing from the broad spirit and scope of the invention. Furthermore, the above-described embodiments are illustrative of the invention and do not limit its scope. That is, the scope of the invention is defined not by the embodiments, but by the claims. Moreover, various modifications implemented within the scope of the claims and their equivalents are considered to be within the scope of the invention.
