Description

  The present invention is a physical load that the adherend receives when recovering from the forward bending posture and the sitting posture to the standing posture by being worn on the body and used by the adherend with the forward bending posture and the sitting posture. Related to assist suits.

  Workers who work in front bend and sit in a factory, etc., workers in nursing facilities, or farm workers, etc., and the adherend with forward bend and sit returns to a standing position The following is known as an example of an auxiliary device worn and used on the body in order to reduce physical load when doing exercise.

  For example, the auxiliary device described in Patent Document 1 arranges an elastic member 10 having elasticity in the bending direction independently on the back of the body so as to extend from the back to the thigh, and the upper end of the elastic member is a vest 20 The elastic member is attached to the body so as to be slidable in the longitudinal direction in the holding portion 21 provided, and the lower end of the elastic member is connected to the thigh belt 30 attached to the thigh and the buttocks connected to the thigh belt 3 The pad 40 is suspended from the vest-like clothes by the connecting belt 50 located on the trunk side, and when it bends forward, the load on the waist is reduced by the restoring force of the elastic member, and the upper surface of the elastic member slides and the body surface of the back of the body Since the change in distance can be absorbed and the movement can be performed without feeling of restraint, and the mounting position of the elastic member is held by the connecting belt, there is no need to tighten the body in the circumferential direction for holding the mounting position.

  However, in this auxiliary device, since the elastic member 10 is fixed to the lower end portion of the thigh belt 30, the elastic member 10 at the time of forward bending operates in series from the thigh to the back through the outside of the buttocks. Because it is connected and curved, it is effective for the resilience during forward bending, but it is inconvenient in use because the sitting posture itself can not be taken.

  In addition, Patent Document 2 discloses a waist load reducing device that can release or return the function of assisting the muscles of the lower back with a simple operation, and passes through the left shoulder, back, right waist, right heel, and right thigh rear surface. It comprises one main member 11 disposed to the right knee, and the other main member 12 disposed to the left knee through the right shoulder, back, left waist, left hip, and left thigh rear surface, The main member 11 and the other main member 12 intersect at the back, and one main member 11 and the other main member 12 are separated below the intersection point 13, and one main member 11 is below the intersection point 13 And the other main member 12 is displaced below the intersection 13 to the left side of the body.

  This stress relief device is specialized in the function of assisting the muscles of the lower back, and hardly contributes to the assisting power when restoring from the forward bending or sitting position to the standing position.

  In addition, Patent Document 3 is a garment that can effectively assist in maintaining the forward inclined posture of the pelvis while stretching the chest, and the back side of the underwear 1 includes the sacrum side of the gluteus maximus muscle and the sacrum concerned. A pattern PA1 is formed to cover the corresponding area so as to locate the corresponding area inside, and the lower area in the area of the front area corresponding to the area where the pattern PA1 is formed in the front area of the underwear 1 is covered A clothes having a pattern PA2 formed thereon and a pattern PB1 which generates tension on both shoulders in a direction to spread the chest when worn is formed on the back surface.

  In the case of this garment, the freedom of movement is maintained only by seaming patterned elastic material on each part of the underwear, but the resilience from forward bending and sitting to standing position There is a problem that the contribution to the operation is small, and setting this to a large value makes the operation itself difficult.

The opening holes 104 and 104a which respectively come out of the upper direction are formed.

  In the present embodiment, the pockets 103 and 103a are formed of nylon belts, but the material is not limited to nylon, and it is also possible to use stretchable material belts, stretch materials, power nets, rubber belts and the like. In addition, the pockets 103 and 103a may be formed directly on the vest back surface 101.

Further, the mounting member 100 is provided with a waist belt 105 which is Rengi the lower end of the best rear portion 10 1. The waist belt 105 can be fixed by winding the waist belt from behind from the back of the adherend and aligning the surface fasteners 107 and 107a with the stop belts 106 and 106a on the front surface.

  The material of the retaining belts 106 and 106a may be made of an elastic material so that the fastening force has a freedom. Moreover, it is preferable to arrange a non-slip (rubber, elastomer, etc.) on the adherend side of the waist belt 105.

Furthermore, the mounting body 100 includes a hip sheet 108 secured below the waist belt 10 5. The buttocks sheet 108 is stretchable, and thigh belts 109 and 109a are formed forward from both sides thereof, and at the left and right ends of the thigh belts 109 and 109a, surface fasteners are respectively provided. Fixing belts 110, 110a are attached. In addition, it is preferable to arrange a non-slip (rubber, elastomer, etc.) inside the thigh belts 109, 109a.

  As a material for forming the buttocks sheet 108, a breathable polyester stretch mesh material can be considered practically, but as long as it has stretchability and durability, other materials such as knit, jersey, power net, rubber, chloroprene and the like can be used. You may use etc.

Furthermore, the mounting body 100 includes a shoulder belt 111,111a formed downward continuously from the pocket 103,103a upper Best rear portion 10 1 along the front of the shoulders the street chest deposition person.

The pockets 103 and 103a, the shoulder belts 111 and 111a, and the locking belts 112 and 112a correspond to the shoulder belt of the present invention.

  Although nylon belts are used for the shoulder belts 111 and 111a and the retaining belts 112 and 112a, elastic elastic material belts and rubber belts are used to increase the adhesion to the body and make the elastic body function effectively while reducing the feeling of buckling. It is also effective to use

In addition, a chest belt fixing strap 114 may be provided to draw and hold the shoulder belts 111 and 111a in front of the chest. The chest belt locking strap 114, shoulder belt 1 11, 1 11a can be prevented from opening to the left and right.

  Although this chest belt fixing strap 114 is configured to be stopped by a resin buckle in this embodiment, other fasteners such as a surface fastener or a snap may be used.

Frame 200 includes a back plate 202 which is built in the back plate pocket 103b formed on the waist belt 105, a belt-like elastic member 215,215a that are riveted 217,217a to the back plate 202.

Band elastic 215,215a extends the shoulder direction of the adherend's in V-shape from the center right of the back plate 202 so as to avoid spinal deposition person. The upper end 216, 216a side of the belt-like elastic body 215, 215a is an opening 103c of the back plate pocket 103b continuous with the pocket opening hole 104, 104a at the lower end of the elastic pocket 103, 103a as shown in FIG. It is slidably inserted from the side, and the side view has an S-shape in accordance with the shape of the back of the adherend.

As a result, since the band-like elastic bodies 215 and 215a do not interfere with the spine, the adhesion of the back surface can also be enhanced without giving discomfort to the adherend.

It is desirable that the belt-like elastic bodies 215, 215a be light-weight so that they can be easily processed into an S-type in a side view while having appropriate elasticity. In the present embodiment, CFRP (carbon fiber reinforced plastic) was used, but it is not limited thereto, and fiber reinforced plastics such as FRP, CFRTP, etc. to which carbon or glass fiber is added, or metals such as aluminum, stainless steel, spring steel etc. It is also possible to use.

  The back plate 202 is provided with the riveting holes and is formed in a curve along the waist. Although a PP material (polypropylene) is used as the material, it is not limited thereto, and a resin such as nylon, polyethylene, fiber reinforced plastic, or a metal plate can also be used.

Further, the band-shaped elastic member 215,215a and the back plate 202 is a structure of freely out from the opening 1 03c of the back plate pockets 1 03b as described above. For this reason, when sweat or stains occur due to work, the belt-like elastic members 215, 215a and the back plate 2
02 can be easily removed to easily wash the assist suit body.

In the above embodiment, the band-like elastic member 215,215a are two, but may be increased to four or more two depending on the strength and quality of the work of the deposition's (4 rows), It is also possible to change the thickness of the material without changing the number of sheets, or to prepare a different elastic force for exchange.

Here, the elastic modulus of the lower bent portion 227 is higher than that of the upper bent portion 226 of the belt-like elastic body 215, 215 a. For example, the elastic modulus of the lower bending portion 227 with respect to the upper bending portion 226 is 110% to 150. Specifically, the upper bending portion 226 is a stack of six CFRP (carbon fiber reinforced plastic) prepregs, whereas the lower bending portion 227 is a stack of eight prepregs, and the change point of the elastic coefficient Is between the upper bending portion 226 and the lower bending portion 227. In addition, in order to make the change in elastic modulus smooth and to prevent the peeling of the prepreg, the lengths of the prepregs added to the lower bent portion 227 are not the same for two sheets, and any different length (for example, one There + 10 mm, the other by a non-equal length) of about -10 mm, and has a structure corresponding to gentle (elastic coefficient) changes.

  The assist suit configured as described above operates as follows.

5 and 6 show a state in which the deposition who wears the assist suit has succumbed before, the buttocks sheet 108 and the waist belt 105 belt elastic member 215,215a during forward bending operation remains in close contact with the body bending of the body It curves in the shape of S shape along, and at this time, energy is stored in the elastic body.

  As a result, when lifting the load, so-called restoring force is exerted to return from the forward bending to the original posture, and the restoring force of the body is assisted by this restoring force.

  FIG. 7 shows a state in which the adherend wearing the assist suit takes a sitting posture, and at this time the waist is bent about 90 degrees at the buttocks sheet 108, and this bending is due to the elasticity of the buttocks sheet 108 The degree of freedom is secured, and the restoring force of the buttock seat 108 acts when restoring to the standing posture.

  Since the assist suit of the present invention can be used in the forms shown in FIG. 5, FIG. 6, and FIG. 7, it is possible to carry forward a load carrying worker, a care facility worker, an agricultural worker, etc. It can be used for all workers with a sitting position and sitting position, and it is also effective for eliminating and correcting body wrinkles during operation attached by many years of work and can be manufactured relatively inexpensively Therefore, it has the potential to spread widely.

  Next, a modified example of the assist suit of the present embodiment will be described with reference to FIG.

  As shown in FIG. 8, if the portion below the buttocks sheet is separable by the fasteners 131 to 133 or the like, only the portion above the waist belt is used, and its use as a sitting posture such as driving or desk work is also possible. It is possible.

Further, sub waist belts 126 and 126 a narrower than the waist belt 105 may be provided above the waist belt 105. Sabukoshi belt 126,126a, for example, at a position above the waist belt 105 is continuously provided from the best rear portion 10 1. In addition, surface fasteners are provided at the distal end portions of the sub waist belts 126 and 126, and can be fixed on the waist belt 105.

The lower bent portion 227 of the belt-like elastic body 215, 215a is brought into close contact with the waist of the adherend by the sub waist belts 126, 126a, thereby suppressing the upward and backward floating of the waist belt 105 to further assist the upper body It can be stabilized.

Moreover, it is preferable that an elastic material is adopted for the pockets 103 and 103a. Thus, the band-like elastic member 215,215a is slidable within the pocket 103, 103a, before it is possible to promote the deformation of the upper bent portion 226 by bending, is not to restrict the operation of the deposition person.

The present embodiment, band-like elastic member 215,215a is back configuration has been described to be housed in the pocket 103, 103a, is not limited thereto, a strip elastic member 215,215a deposition person The back strap belt may be a suspender or the like as long as the back strap is in close contact with the belt.

Moreover, in this embodiment, although the case where the back plate 202 and the strip | belt-shaped elastic body 215, 215a were connected by riveting was demonstrated, it is not limited to this, Connection methods other than a rivet may be used.
