JP6092747B2 - How to use the work tool auxiliary belt - Google Patents

Description

The present invention relates to a method for using a work tool auxiliary belt that reduces and shares a load applied when the work tool is used.

Conventionally, shoulder pads and shoulder belts are widely used for bags and heavy electric tools carried over the shoulder, such as a brush cutter and a sprayer (see Patent Document 1).
These are designed to ensure freedom of both hands, to reduce the burden on the hands and the pressure on the neck, and are intended to be hung from the shoulder, but are often attached to individual items. Were limited, such as being used on certain work tools.

  Further, when a child is held in a standing posture, a load is applied forward and downward, so that arm force is required to support it, and a burden is applied because the waist serves as a fulcrum. In order to solve these problems, various straps have been devised.

Furthermore, hard work using working tools, such as farm work, snow throwing, and construction sites, is difficult and difficult for women and elderly people as well as those who are used to it.
In particular, when working with a handle or handle, whole body movements, such as scooping up and throwing away using a scoop or lifting and swinging down like a pickaxe, require arm strength and back strength, mainly on the waist, knees, and arms. It was heavy labor that put a burden.

JP 2004-49621 A

The invention of Patent Document 1 is an invention made to fix a shoulder pad to the shoulder ridge for the purpose of preventing the shoulder belt lowered from the shoulder to move sideways and biting into the neck. The belt is annular and a heavy electric tool is suspended at one point by a suspension hook at the lower end. In addition, there are many things that carry the infant on a string (belt) hung from the shoulder so that it is easy to hold the infant or wrap the entire body.
Conventional shoulder pads and shoulder belts are designed to reduce the load load and release both hands by sorting and suspending items carried from the shoulder. I haven't seen many used for shovels, snow throwing tools, pickaxes, etc. Many of the shoulder pads can be adjusted with a belt loop, but once they were adjusted according to the user's physique, they were almost fixed.

  As mentioned above, work with handles and handles at farm work, snow throwing, construction sites, etc., for example, work with a scoop or pickaxe requires arm strength and back strength in a middle waist posture, mainly on the waist, knees and arms There was a need for an assistive device that can be used by both men and women, a burdensome and heavy labor that reduces and divides the physical burden.

In addition, many straps that are convenient for holding an infant in a standing posture have been devised, but the infant's posture is also cramped because it is used in a fixed shape, and the person holding it further There is a drawback that a certain part of the infant's body is loaded.
The problem is to solve these problems.

In order to solve the above-mentioned problems, the present invention is such that the shoulder pad 1 distributed from the shoulder to the front and back is flat and long in the front and rear direction, so that the contact surface with the body is taken to prevent slipping and the shoulder pad 1 is pressed against the shoulder. It is formed with cushioning so as to minimize the above. Both ends of the sliding belt 2 that is gently inserted into the hollow portion in the longitudinal direction of the shoulder pad 1 are folded back to form the rings 4 and 4 via the length adjusting fasteners 3 and 3. 4 is used to provide a method for using a work tool auxiliary belt, wherein the work tool handle and the handle are gripped in front and back.

Further, in the work tool auxiliary belt , the ring rings 4 and 4 and the work tool are provided by hook and loop fasteners 7 and 7 provided on the surfaces of the connecting belts 6 and 6 fixed to the pair of bracelet belts 5 and 5 at the opposite ends. Provided is a method for using a work tool auxiliary belt , characterized in that the handle and the handle are connected so as to be gripped.

1. Applying the principle of pendulum and lion, reduce the burden on the body of hard work and hard work and share it.
2. Since it is a simple structure, it can be made inexpensive.
3. Can be used regardless of age or sex.
4). It can also be applied to elderly care and welfare in an aging society with a shortage of caregivers.
5. In particular, since the burden on the arms, knees, and waist is reduced, the effect of preventing muscle pain and back pain is great.
6). The wide shoulder pad 1 distributed to the shoulders covers from the front of the chest to the bottom of the scapula, so it has high frictional resistance and cushioning, so there is little pressure on the shoulder.

Explanatory drawing at the time of working tool wearing of Example 1 Example 2 Explanatory drawing at the time of working tool wearing of Example 2

As described above, the conventional shoulder belt is an accessory of a carried item, or a subject that is directly suspended and receives a load with a solid shoulder.
The present invention, on the other hand, applies the principle of pendulum and lever with the shoulder as a fulcrum. ,

  A first embodiment of the present invention will be described with reference to FIG. The shoulder pad 1 is flat and slightly wide, and is formed longer than a normal shoulder pad so as to increase frictional resistance with the body. (The length of the front and back of the shoulder pad is approximately from the lower chest to the lower part of the scapula.) Next, the shoulder pad 1 has a hollow portion that is wider than the sliding belt 2 and is formed in the longitudinal direction. The sliding belt 2 gently inserted into the hollow portion is folded at both ends, and the length adjusting fasteners 3 and 3 form the annular rings 4 and 4 according to the user's physique. The rings 4 and 4 are used to grip the front and back of the work tool with appropriate intervals. By holding the part that is distributed and gripped from the shoulder with both hands, the sliding belt slides against the shoulder pad with the shoulder as a fulcrum, and the position of the force point and the point of action can be changed arbitrarily. Is.

Next, Example 2 will be described with reference to FIG.
In addition to the first embodiment, connection belts 6 and 6 fixed to a pair of bracelet belts 5 and 5 are provided. A pair of hook-and-loop fasteners 7 and 7 are provided on the front and back sides of both ends of the connecting belts 6 and 6 to form a ring. The connecting belts 6 and 6 are connected through the circular rings 4 and 4 at the end of the sliding belt. Are fixed together. Both hands are put into the connected bracelet belts 5 and 5 and work is performed with the handle of the work tool and the front and back of the handle. It is preferable to grip the connection belts 6 and 6 when working.

Thus, although to work with a working tool connected to a sliding belt which is distributed to the front and rear Ategai shoulders central portion of the shoulder pad 1, in accordance with the movement of the user, the shoulder pad 1 Since the sliding belt 2 that is gently penetrated slides back and forth, the position of the force point and the operating point is always distributed in a well-balanced manner with the shoulder as a fulcrum.
In addition, the bracelet belts 5 and 5 bring about the effect that the connection belts 6 and 6 holding the handle of the work tool and the front and rear of the handle do not shift toward the center of the handle and the handle.

  For example, in the operation using a scoop, in the operation to insert forward, the force is amplified because it moves toward the object vigorously with the principle of the pendulum using the shoulder as a fulcrum, and in the next operation to lift up, the principle of the insulator is applied, By pushing down the distance of the handle, which is the point of force, and pushing it down, the point of action only needs to be oriented, and the lifting force may be small.

  Also, when holding an infant, the same posture places a burden on the infant and certain parts of his body. However, in the present invention, the movement of the center of gravity and the posture holding the infant can be changed by moving the sliding belt 2. You can also change the load position on your body.

In the practice of the present invention, cloth, leather, resin material, etc. are suitable, but the surface of the shoulder pad 1 that is in contact with the body is subjected to anti-slip processing that increases frictional resistance and cushioning is added to prevent compression. It is desirable to use a material having excellent slidability on the surface that the sliding belt 2 contacts. Moreover, as an alternative to the hook-and-loop fasteners 7 and 7 provided on the connecting belts 6 and 6 used for connecting the rings 4 and 4 to the handle and handle of the work tool, it is easy to attach and detach hook hooks and strong hooks. A simple locking device can also be used.

  It is a well-known fact that hot weather and heavy rains continue throughout the country in the summer, due to abnormal weather, and it is a well-known fact that scoops are also active in disaster recovery. Conversely, heavy snow areas increase in winter However, in a society with a declining birthrate and an aging society, snow throwing is a hard work that requires arm strength and back strength, and the burden on the body is large. The same applies to agricultural work, snow removal, and construction sites, and there is a demand for an auxiliary tool that reduces and shares the burden on those engaged in them. Although the present invention has a simple structure, it applies the principle of pendulum and lever and can be used regardless of age or gender, and can be manufactured at a low price, so it is an industrially useful invention for an aging society. .
