Description

  The present invention relates to a belt that is attached to the body and mainly suspends a working machine body such as a power mower.

  A hand-held work machine equipped with a power source at the base end of an operating rod such as a mower and having a rotary blade attached to the tip performs a predetermined work by being suspended from a suspension belt attached to the body.

  The suspension belt basically bears the weight of the airframe by the shoulder. For example, in Patent Document 1 (Japanese Patent Laid-Open No. 7-264914), both shoulder bands and a hanging band are provided on the upper side and a lower band from the branched body on the back, and one of the both shoulder bands and the hanging band is connected. At the connection point and one of the hanging bands, the equipment is suspended and the protective cover surface is attached.

  Patent Documents 2 and 3 are suspensions on one shoulder, and Patent Document 2 (Japanese Patent Laid-Open No. 2011-160717) is designed to apply a load to the shoulder of the device that is suspended. 2004-275062) is slanted, has a waist band, and is provided with a magnetic protrusion especially on the shoulder pad so that the health promotion effect and the acupressure effect are exhibited.

JP-A-7-264914. JP, 2011-160717, A. Japanese Patent Application Laid-Open No. 2004-275062.

  Like the mowing work, if the operator himself holds the aircraft with the appropriate weight and works for a long time, the burden on the body is large, especially the mowing work is often done on sloping ground, and the body is balanced. In addition to simply suspending and holding the aircraft, a burden is also applied to the waist. Furthermore, since these operations are performed for a long time, the workers are tired and distressed.

  However, the working machine suspension belt described in each of the above-mentioned patent documents only considers the reduction of the burden on the shoulder, such as holding both shoulders and a shoulder pad provided with magnet protrusions. However, when a load is applied to the shoulder, the function of the muscles, that is, the raising of the scapula, the lower rotation inversion, the upper rotation, the extension of the head and neck, and the like are hindered, and fatigue tends to accumulate.

  Therefore, the present invention focuses on reducing the burden on the shoulders, and also bears the weight of the fuselage in the lower back, and further stimulates specific parts of the body to activate muscle strength. It proposes a working machine suspension belt provided with a section.

  A working machine suspension belt according to the present invention (Claim 1) includes a waist belt band having band connecting portions at both ends, a shoulder belt band that can be connected to and detached from the position where the waist belt band is biased, and a waist belt body. A lower abdomen belt belt that is sewed symmetrically at the center lower side and provided with a band connecting part at both ends, and a working machine suspension belt provided with an air suspension part near the connection position of the shoulder belt band. The muscles are pressed against the lumbar back contact area and the abdomen both sides contact area on the inner side of the waist belt band, the shoulder belt back contact area on the shoulder belt band, and the buttocks contact area on the lower abdomen belt band. The present invention is characterized in that a buffering projection for stimulating is provided.

  Therefore, the belt has a waist belt belt attached to the waist, a shoulder belt belt is slanted, the lower abdomen belt belt is firmly connected in front of the lower abdomen, and a predetermined work machine is suspended from the airframe suspension. Thus, a predetermined work is performed.

  In particular, the belt is provided with a buffer protrusion at a predetermined position, and presses and stimulates a predetermined part of the body when the body is worn (during work).

  Specifically, the buffer protrusions on the back of the lumbar region (lumbar buffer protrusions) are located on the proximal part of the muscle start and the muscle tail of the psoas major muscle, longest chest muscle, multifidus, etc. Abdominal buffer projections) are the proximal proximal muscles such as the iliopsoas muscle, and the shoulder front and back buffer projections (shoulder cushion projections) are the trapezius, scapula, deltoid, great pectoralis The proximal part of the muscle, such as the buttock cushioning projection (the buttock cushioning projection), presses the proximal part of the muscle, such as the large, gluteus medius, and the femoral tension muscle.

  A pressure stimulus to the proximal muscle start or tail proximal part releases the excessive tension of the muscle and gives moderate tension when it is relaxed. As a result, the range of motion of the body is increased at the same time as the muscular strength is increased, and as a result, the accumulation of fatigue (until pain occurs) is moderated, and the pain of work is relieved.

  According to a second aspect of the present invention, the belt for suspending the work machine body includes a shoulder belt band formed of a belt main body and a shoulder support member that can be attached to a desired position of the belt main body, and a buffer protrusion is formed on the shoulder abutment. It is possible to adjust the mounting position of the shoulder support member, and only one place for adjusting the length of the shoulder belt band is sufficient.

  In addition, the working machine suspension belt according to claim 3 of the present invention is formed by interposing a stretchable rubber band part in a part of the lower abdomen belt band. It is possible to tighten.

  The configuration of the present invention is as described above. When the body is worn, the buffer projection part presses and stimulates a predetermined position of the body, thereby enhancing the function of the muscles and reducing the physical burden during work.
