An assist suit with a safety function according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a view of a worker wearing an assist suit with a safety function according to an embodiment of the present invention as viewed from the rear. FIG. 2 is a view of a worker wearing an assist suit with a safety function according to one embodiment of the present invention as viewed from the front.
As shown in FIGS. 1 and 2, an assist suit with a safety function (hereinafter, simply referred to as an assist suit) 100 according to the present embodiment includes a mounting member 1 and a safety function member 3.
In the following description, the terms “up”, “down”, “front”, “rear”, “left”, and “right” are used by the worker H wearing the assist suit 100 unless otherwise specified. Means “up”, “down”, “front”, “rear”, “left”, and “right”.

  The mounting member 1 can be mounted on the body of the worker H. The mounting member 1 includes a back mounting portion 11, a pair of left and right shoulder mounting portions 12, and a waist mounting portion 13. For example, the mounting member 1 is made of a cloth or the like having a predetermined flexibility and elasticity.

  The back mounting portion 11 is arranged from the shoulder to the waist of the worker H's back. The back mounting part 11 is formed so that the width in the left-right direction gradually increases from the upper back to the lower back.

  The back mounting part 11 has an elastic member 11a that assists in a direction to raise the posture when the worker H is in the forward bending posture. The elastic member 11a is a member having an elastic force that tends to return to its original state when bent.

  The upper end of the elastic member 11 a is fixed to the upper part of the back mounting part 11, and the lower end is fixed to the waist mounting part 13. The lower part of the elastic member 11a is provided with a vertically extending through hole 11b. Thereby, the elastic member 11a can easily cope with the rotation around the waist.

  The left and right shoulder mounting portions 12 each extend upward from the upper end of the back mounting portion 11, are folded at the upper end of the shoulder of the worker H, and extend to the front of the worker H.

  Each shoulder mounting portion 12 is provided with a shoulder belt 22. The shoulder belt 22 extends from the back side (rear side) of the shoulder mounting portion 12 to the chest side (front side). A lower end on the chest side of the shoulder belt 22 is connected to the waist mounting portion 13. A buckle 22a is provided on the shoulder belt 22, and the length of the shoulder belt 22 can be adjusted. On the chest side of the shoulder belt 22, an annular member 22b having an annular shape is provided.

FIG. 3 is a schematic diagram showing a configuration of the shoulder mounting portion 12 and the shoulder belt 22. The right side of the drawing shows a state before the shoulder belt 22 is fixed to the shoulder mounting portion 12, and the left side of the drawing shows a shoulder mounting portion 12 and the like. 2 shows a state in which the shoulder belt 22 is fixed.
As shown in FIG. 3, hook-and-loop fasteners 29 are provided on both sides of the shoulder mounting portion 12 in the width direction. The shoulder belt 22 is arranged on the shoulder mounting portion 12 (on the side opposite to the back side of the worker H). The hook-and-loop fastener 29 is folded over the shoulder belt 22 (the side opposite to the back side of the worker H). In a state where the shoulder belt 22 is sandwiched between the shoulder attachment portion 12 and the hook-and-loop fastener 29, the tip portions of the hook-and-loop fastener 29 are fixed to each other. The upper end of the elastic member 11a (see FIG. 1) is fixed to the back mount 11 connected to the lower end of the shoulder mount 12.

  The left and right shoulder belts 22 are connected by a chest belt 24. The chest belt 24 extends in the left-right direction. A buckle 24a is provided on the chest belt 24 so that the length of the chest belt 24 can be adjusted.

  The waist attachment part 13 is arranged so as to surround the waist of the worker H. The lower end of the back mounting portion 11 and the lower end of the shoulder belt 22 on the chest side are connected to the waist mounting portion 13, respectively. The waist attachment portion 13 is configured to be able to expand and contract along the waist of the worker H.

  A waist belt (waist belt portion) 23 is provided on the front side of the waist mounting portion 13. The waist belt 23 extends in the left-right direction. A buckle 23a is provided on the waist belt 23 so that the length of the waist belt 23 can be adjusted.

  A blower fan (blower unit) 13a that blows air toward the worker H is provided behind the waist mounting unit 13. The blower fans 13a are provided on both left and right sides.

  A pair of right and left thigh belts 25 are provided on the waist attachment portion 13. Each thigh belt 25 is formed in a tubular shape, disposed along the thigh from the buttocks of the worker H, and wound around the thigh. A buckle 25a is provided on the thigh belt 25 so that the length of the thigh belt 25 can be adjusted.

  The safety function member 3 is connected to the mounting member 1. The safety function member 3 has a pair of left and right lanyard parts 31 and a hook part 32.

  One end side of each lanyard portion 31 is connected to the back side (rear side) of the shoulder mounting portion 12 via an annular member 31a having an annular shape.

  A hook 32 is provided at the other end of each lanyard 31. The hook 32 can be opened and closed. The hook portion 32 is engaged with an annular member 22b provided on the chest belt 24 when not in use, and is engageable with a rope or the like (not shown) provided on a support when used.

  In the assist suit 100 thus configured, the back mounting portion 11, the pair of left and right shoulder mounting portions 12, and the waist mounting portion 13 are arranged along the body of the worker H, and the mounting member 1 is mounted on the worker H. You. Since the mounting member 1 is provided with the safety function member 3, if the mounting member 1 is mounted, the safety function member 3 is also mounted. Therefore, the mounting member 1 and the safety function member 3 can be mounted simultaneously and without trouble.

  Further, when the worker H is in the forward bending posture, the elastic force of the elastic member 11a of the back mounting portion 11 to return to the original position assists the worker H in the direction to raise the posture. The posture of the person H is correctly maintained, and the burden on the back and waist is reduced.

  In addition, since the waist mounting portion 13 is extendable and contractable along the waist of the worker H, the load on the waist is reduced by tightening the waist mounting portion 13 on the waist of the worker H. Further, by tightening the waist belt 23 from above the waist mounting portion 13, a displacement or the like of the waist mounting portion 13 is suppressed.

  In addition, when working at a high place, the waist belt 13 is used to fasten the waist mounting portion 13 to the operator's waist, and the hook portion 32 provided on the lanyard portion 31 connected to the mounting member 1 is locked at a predetermined position. Since it is possible to perform the work while keeping the work, the safety of the worker H can be ensured.

  Further, even if the worker H is hung on the lanyard part 31 during the work at a high place, the waist belt 23, the chest belt 24 and the thigh belt 25 are provided, so the waist belt 23 and the thigh belt are provided. The belt 25 prevents the waist mounting portion 13 from falling off the operator, and the chest belt 24 suppresses the shoulder mounting portion 12 from falling off the operator.

  In addition, since the blower fan provided in the waist mounting portion 13 blows air toward the body of the worker H, the worker H can work in a comfortable environment.

  The various shapes, combinations, and the like of the constituent members shown in the above-described embodiments are merely examples, and can be variously changed based on design requirements and the like without departing from the gist of the present invention.

  For example, in the embodiment described above, the blower fan 13a is provided on the rear surface of the waist mounting portion 13, but the present invention is not limited to this. The blower unit may be provided on the back mounting unit 11 or the like, or may not be provided.

  Further, in the embodiment described above, the waist mounting portion 13 is configured to be able to expand and contract along the waist of the worker H, but the present invention is not limited to this, and the waist mounting portion 13 is configured to be able to expand and contract. You do not have to.
