  The present invention mainly relates to a working belt suitable for work carried by suspending and carrying various tools and parts materials.

  It is known that the work belt has a structure that relaxes the tightening of the wearing belt on the body by overlapping the wearing belt for wearing on the body on the wide waist belt, especially the wide waist belt is breathable In order to provide cushioning properties, a net-like cloth or a porous member is laminated (Patent Document 1).

  In order to reduce the physical burden on the wearer by suspending heavy tools from the waist, a protrusion (cushion pad) is provided on the belt for the purpose of maintaining the wearer's health, and a magnet is provided on the cushion pad. A working belt provided with an element is known (Patent Document 2).

Utility model registration No. 3152318. Japanese Patent Application Laid-Open No. 2007-7835.

  It is widely known that when working with heavy tools suspended on the waist, a large burden is applied to the waist and unbalanced force is applied to the muscles to support the body, causing back pain. The present invention proposes a working belt that activates muscle strength by stimulating a specific body part and reduces the physical burden on the belt wearer.

  The working belt according to the present invention is a waist belt belt, a wearing belt belt provided with a body wearing mechanism superimposed on the outer surface of the waist belt belt, and both sides are separated from the waist belt belt, A working belt composed of a lower belt belt connected to the lower central belt edge of the waist belt belt at the upper edge of the central portion, the waist belt belt having shape retention, flexibility and breathability, The four first protrusions that are wide and gradually formed narrow on the left and right sides, and pressed against the left and right and upper and lower sides of the lumbar vertebra when worn on the body, and the first protrusions laterally spaced apart at appropriate intervals The lower belt belt is provided with connecting parts for body wearing at both ends, and a second protruding part connected to the first protruding part is provided.

  Thus, the working belt has a waist belt belt wrapped around the body from the back to the front, the waist belt belt is attached to the body with the wearing belt belt, and the end of the lower belt belt is further rotated forward. Attach to the body by tightening at the lower position of the wearing belt. The tools are carried by hanging on a mounting belt or hanging on a hanging ring attached to a waist belt.

  In particular, when the work belt of the present invention is tightly attached to the body, each projecting portion applies pressure to a predetermined position of the body, and the upper first projecting portion is a muscle tail muscle such as the longest chest muscle, multifidus muscle, rotator muscle, etc. Proximal pressure is applied, the lower first protrusion is applied to the proximal part of the muscles such as the psoas major, lumbar quadrilateral, and lumbogastrocnemius, and the lateral protrusion is the gluteal, large, medium, small, femur Apply pressure to the proximal muscle origin, such as the tension muscle, and the second protrusion applies pressure to the inner oblique and lateral abdominal muscles. It also plays a role of supporting the belt belt.

  The structure of the present invention is as described above. In contrast to the contraction of muscles, the property of relaxing by applying external pressure to the muscles, or the property of contracting one of the muscles contracting across the joints to the muscle contraction or nearby. Focusing on the nature of antagonizing muscles that contract and tension, and the principle of muscles that co-contract when external pressure is applied to both the main and antagonist muscles (muscle co-contraction), the body moves by applying pressure to a predetermined position of the body when wearing a work belt In contrast, it causes adaptive muscle tension or relaxation by the forced external pressure effect, expands the range of motion of joints that humans can naturally have, and strengthens muscles related to human body posture or movement. In this way, muscle strength has been increased, body fatigue has been reduced, back and back pain, injury prevention, and workability have been improved.

The measurement result table | surface of the trunk movable range before mounting | wearing with the working belt of embodiment, and after mounting | wearing. Measurement result table of the same muscle strength.

  Next, an embodiment of the present invention will be described. The working belt shown in the embodiment includes a waist belt 1, a wearing belt 2, and a lower belt 3. The waist belt 1 is wide (about 16 cm) at the center, gradually narrowed to the left and right (about 10 cm), and has a total length of about 70 cm. The whole has moderate shape retention, flexibility and breathability. A surface canvas 11, a rubber net 12, and a fluffed net cloth 13, and first upper and lower first protrusions 14 and 15 and side protrusions 16 are provided at predetermined positions. In addition, a trapezoidal connecting band portion 18 is sewn at the center of the back surface (the body side when worn on the body), and a belt passing portion 19 is provided on the front surface.

  In particular, the first projecting portions 14 and 15 and the side projecting portions 16 are formed by using a hard cushion plate material as a core material, covering with a cover cloth, and being attached to each belt belt. Is a vertical length of 37 mm (35 to 40 mm), a horizontal width of 65 mm (60 to 70 mm), a thickness of about 15 mm, and the arrangement is such that the distance between the left and right cores of the upper first protrusion 14 is 85 to 95 mm, and the lower first The left-right interval of the core material of the protrusion 15 is 120 to 130 mm, and the gap between the upper first protrusion 14 and the lower first protrusion is 30 to 35 mm.

  Moreover, the core material of the side protrusion 16 is about 55 * 55 mm, and the edge of the center side is provided in the position of 24-25 cm from the belt center. The wearing belt band 2 is worn on the waist belt band 1 through a belt passing part 19 and is provided with a body wearing mechanism (belt connecting part) at both ends.

  The lower belt band 3 is not formed in parallel with the waist belt band 1 but has a narrow belt shape with a vertical width of 75 mm that is separated from the waist belt band 1 on both sides. A trapezoidal connecting band 18 sewn at the upper and lower edges of the belt and the upper and lower edges of the center of the lower belt band 3. Connecting portions (surface fasteners) 31a and 31b are provided.

  Moreover, the 2nd protrusion part 32 which covered the core material with the cover cloth and was provided similarly to the above-mentioned 1st protrusion parts 14 and 15 is provided, and the 2nd protrusion part 32 is provided in the 1st protrusion parts 14 and 15. At the continuous position, the distance between the left and right cores is about 12 cm.

  Thus, the working belt is provided with the waist belt 1 attached to the body of the worker A in the same manner as the conventional waist belt, and is further attached with the lower belt 3 to suspend the tool such as a tool insert. The member is appropriately hung on the wearing belt band 2 or is hung on a hanging ring or the like attached to the waist belt band 1 and carried.

  In particular, when the work belt is tightly attached to the body, the upper first projecting portion 14, the lower first projecting portion 15, the side projecting portion 16, and the second projecting portion 32 press the predetermined positions of the body, respectively. Appropriate stimulation is given to the predetermined muscles of the worker to enhance the physical ability and relieve the physical burden of the worker.

  Specifically, 38 people in their 20s and 60s compared with physical strength measurements before and after wearing the work belt. For example, as shown in FIG. 5, the trunk range of motion (the forward bending distance of the limbs) increased in numerical values on all surfaces.

  Also, the result of measuring the weight that can lift the heavy object vertically by extending the knee 30 cm away from the heavy object at a height of 70 cm (back muscle group measurement result: Table 1), supine and fixing the ankle As a result of holding a heavy object on the chest and measuring the weight of the abdominal muscles (muscle strength measurement result of the abdominal muscle group: Table 2) As a result of measuring the weight that can be lifted by bending the knee (muscle strength measurement results of the toes muscle group: Table 3), standing upright, extending the elbow with any one arm, 30 cm away from a heavy object at a height of 85 cm The result of measuring the weight that can be lifted with one hand at the spot (muscle strength measurement result of arm and arm muscle group: Table 4) was obtained.

  As described above, by wearing the working belt of the present invention, the physical ability is enhanced, and as a result, the burden on the body when the tools are carried is reduced.
