Description

[Detailed description of the invention] [Industrial application field]

TECHNICAL FIELD The present invention relates to a shoulder-type mower that allows stable work to be carried out while hanging on the shoulder using a shoulder band. [Prior Art] Conventionally, a commonly known tortoise mower is equipped with an engine C at the rear end of an operation rod having a cutting blade a at the tip, and an operation handle d at the middle of the operation rod. A so-called shoulder-type mower is known in which a hanger e provided on a rod is engaged with a hook of a shoulder band f to suspend the mower (see FIG. 4). Here, the shoulder band f has a loop shape, and the hanger e engages with the hook of the shoulder band r.
is located between the operating handle d and the engine C and slightly behind the center of gravity G.

[Problem to be solved by the invention]

In such a shoulder-type mower, the operating rod is suspended by the shoulder band f at one point behind the center of gravity @G, so there is always a downward force on the cutting blade a at the tip of the operating rod. acts. Therefore, both in surface mowing work in which the operating rod is tilted diagonally downward and in slope mowing work in which the operating rod is tilted diagonally upward. The operator must constantly lift the operating handle d to balance the cutting blade a at a constant height, which places a heavy burden on the operator. Furthermore, since the shoulder band f is loop-shaped, it comes in close contact with the worker's chest and puts pressure on it, making it uncomfortable to wear. SUMMARY OF THE INVENTION Therefore, the present invention provides a shoulder-type mower that reduces the feeling of pressure on the chest, provides a good device i1g that is easy to adjust, and allows the cutting blade to be hung at a predetermined height in a stable balance. The purpose is to

[Means to solve the problem]

For this purpose, the present invention provides a shoulder-mounted mower in which the main body of the mower, which has a cutting blade at the tip of the operating rod, an engine at the rear end, and an operating handle in the middle, is suspended via a shoulder band. The lawn mower is equipped with a hanger on the holder of the operation handle located in front of the center of gravity of the mower body and on the engine located behind the center of gravity, and the shield band is hooked to the hanger on the holder side. a front support band that removably engages with a hanger on the engine side through a hook; a rear support band that removably engages with a hanger on the engine side through a hook; a pair of left and right shoulder rests that are continuous with the rear support band; an adjuster fixed to the front end of one shoulder rest, and an adjustment that is continuously pushed through the front end of the other shoulder rest through the connecting ring of the front support band and is locked to the adjuster to adjust the length. Comes with a band.

[For production]

In such a means, the shoulder band suspends the mower main body at 2WJ in front and behind the center of gravity using the worker's shoulder as a fulcrum. Therefore, only the pair of left and right shoulder rests come into contact with both shoulders of the worker, and do not put pressure on the chest or back of the worker. Here, when the center of gravity of the mower body is located below the shoulders of the operator, the mower body stands still with its weight balanced back and forth. Therefore, by shifting the contact point between the worker's shoulder, which is the fulcrum position, and the shoulder rest back and forth, the operating rod can be tilted at any angle and the cutting blade can be suspended at a predetermined height in a stable balance. I can hold it. In addition, since the adjustment band is movable relative to the connecting ring of the front support band, the pair of left and right shoulder rests contact both shoulders of the operator without loosening. Therefore, the load is applied evenly to both shoulders of the worker, providing a good wearing feeling. Furthermore, the length of the shoulder band can be adjusted only by adjusting the locking position of the adjustment band with respect to the adjuster.
The adjustment work is easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 indicates a main body of a shoulder-type mower, and reference numeral 2 indicates a shoulder band for suspending the main body I of the mower. The mower main body 1 is equipped with a cutting blade 4 at the tip of an operating rod 3 and an engine 5 at the rear end of the operating rod 3. The cutting blade 4 is rotatably driven by the rotational driving force of the engine 5 via a drive shaft (not shown) inside the operating rod 3. A safety cover 6 for the cutting blade 4 is attached to the tip of the operation rod 3, and a pair of left and right horn-shaped operation handles 8 are attached to the middle portion of the operation rod 1 via a holder 7. Here, the center of gravity of the mower body 1 is located at the holder 7.
An arc-shaped hanger 910 is fixed to the holder 7, which is located near the middle between the engine 4 and the center of gravity, and to the holder 7, which is located in front of the center of gravity, and to the engine 5, which is located behind the center of gravity. These hangers 910 protrude upward along a direction perpendicular to the operating rod 3. On the other hand, the shield band 2 includes a front support band 12 that is detachably attached to the hanger 9 on the holder 7 side via a hook II, and a front support band 12 that is detachably attached to the hanger 9 on the side of the engine 5 via a hook I3. and a rear support band 14 that engages with the rear support band 14. These front support band 12 and rear support band 14 have adjusters 15.1 on the way.
6 so that the length itself can be adjusted. Here, a connecting ring 17 is attached to the upper part of the front support band 12.
is attached, and a pair of left and right shoulder rests 18 and 19 are continuous on the upper part of the rear support band 14. Further, an adjustment band 20 of a predetermined length is continuous to the front end of 18 in one shoulder rest, and an adjuster 21 is attached to the front end of 19 in the other shoulder rest. The adjustment band 20 is inserted through the connection ring 17 at the upper end of the front support band 12, and its tip is locked to the adjuster 21. In the above configuration, the operator passes his head between the pair of left and right shoulder rests 18 and 19 of the shoulder band 2, places them on both shoulders, and suspends the mower main body l. In this case, the length of the shoulder band 2 is adjusted depending on the physique of the worker, such as his height. This adjustment work can be easily performed by simply changing the locking position of the adjustment band 20 with respect to the adjuster 21. When the shoulder-type mower is mounted, the load on the front support band 12 side acts on the left and right shoulder rests 18 and 19 via the adjustment band 20. In this case, the adjustment band 20
is movably inserted into the connecting ring 17 at the upper end of the front support band 12, so the left and right shoulder rests 18, 19 loosely touch (contact) both shoulders of the worker. The load is applied evenly and a good wearing feeling can be obtained.In addition, as shown in Figures 2 and 3, the shoulder band 2 has only the left and right shoulder rests 18 and 19 in contact with both shoulders of the worker. Therefore, there is no pressure on the chest or back of the worker.Here, the mower main body l, which is suspended using the worker's shoulder as a fulcrum, has its center of gravity [ilG] located below the worker's shoulder. At that point, the weight is balanced back and forth and it comes to rest.Therefore, by shifting the contact position between the worker's shoulder, which is the fulcrum position, and the shoulder rest 18, 19 back and forth, the operating ring 3 can be moved as shown in Figure 2. Even in downward sloping plane mowing operations or third
Even in slope mowing work where the operation ring 3 is inclined upward as shown in the figure, the cutting blade 4 can be suspended and held at a predetermined height position in a stable balanced state. Therefore, there is no danger even if you temporarily remove both hands while working, and the work can be done easily. [Effects of the Invention] As explained above, according to the present invention, the shoulder band suspends the mower main body at two locations, front and rear of the center of gravity, using the worker's shoulder as a fulcrum. Therefore, only the pair of left and right shoulder rests come into contact with both shoulders of the worker, and do not put pressure on the chest or back of the worker. Here, when the center of gravity of the mower body is located below the shoulders of the operator, the mower body stands still with its weight balanced back and forth. Therefore, by shifting the contact position between the worker's shoulder, which is the fulcrum position, and the shoulder rest back and forth, the operating ring can be tilted at any angle, and the cutting blade can be kept at a predetermined height in a stable balance. Can be hung. In addition, since the adjustment band is movable relative to the connecting ring of the front support band, the pair of left and right shoulder rests come into contact with both shoulders of the operator without loosening. Therefore, the load is applied evenly to both shoulders of the worker, providing a good wearing feeling. Furthermore, the length of the shoulder band can be adjusted only by adjusting the locking position of the adjustment band with respect to the adjuster.
The adjustment work is easy.
