Description

  The present invention is attached to the body in each case of performing various operations involving long-time work in a forward bending posture or repeated posture change from a forward bending posture to an upright posture, which causes back pain. The present invention relates to a muscular strength assisting device that assists the muscular strength necessary when returning from a forward bending posture to an upright posture.

There are several proposals for this type of muscle strength aid.
Patent Document 1, which is one of them, is a tight waist prevention device, which consists of a pair of traction bands that are worn from one shoulder to the other leg through the buttocks and worn on the human body, One end of each traction band is provided with an annular hook part that is hooked on a shoulder, and the other end of each traction band is provided with an annular leg hook part that is hooked on a foot, and each traction band is provided with A length adjusting means is provided.

  According to the tight waist preventive device of Patent Document 1, it is possible to adjust the length regardless of the height of the wearer, and when taking a forward bending posture, the upper body is above a certain angle. Although there is an advantage that it is supported not to bend, the support is limited to a certain angle, and there is a disadvantage that it is not supported at other angles. In addition, it is worn from the shoulder to the foot, and it is difficult to wear it on the body.

  Patent Document 2, which is the second, is a jacket with elastic members, which includes linear spring members made of a shape memory alloy in which upper and lower portions are inserted into upper and lower hollow bodies, one on each side of the apron. This is to be used by attaching it to the vicinity of the thigh from the chest on the front side of the wearer.

  According to the clothes with an elastic member of this patent document 2, it seems that the operation | work which needs a forward bending can be done somewhat easily. However, this elastic member-equipped clothing is one in which the spring member is placed on the front surface of the body of the wearer, and this tends to be an obstacle in the work, and when the body is bent forward, the lower end of the spring member May hit the thigh and injure the thigh.

  Patent Document 3, which is the third, is a forward bending work assisting tool, which is arranged on the back of the body independently on the left and right sides, the upper end is located on the back, the middle passes through the buttocks, and the lower end reaches the thigh. A vest-like garment having two elastic members having elasticity, holding portions for holding the elastic members so as to be slidable in the longitudinal direction on both sides of the back surface, and locking the lower end of the elastic member to the thigh Two thigh belts connected to the back upper ends of both the left and right thigh belts, a buttock pad disposed between the buttock and the elastic member, the upper left portion of the buttock pad and the vest Each of the connecting belts connecting the lower left part of the garment, the upper right part of the butt pad and the lower part of the starboard of the vest.

  Therefore, according to the forward bending work auxiliary tool of Patent Document 3, since the elastic member behind acts in the direction causing the upper body in the forward bending work, the work can be performed easily and the risk of hurting the waist is reduced. It seems certain that it will be possible. However, although the upper end of the elastic member is slidably connected to the back side of the vest-like garment, the upper end of the elastic member is relatively As a result, it is difficult to descend smoothly, and as a result, the thigh belt is forced to be pulled up, or the elastic member is pushed down when the body is raised, resulting in damage to the thigh. The fear that it will end up arises. Furthermore, since the elastic member passes over the buttocks, there is a problem that it is impossible to sit on a chair or the like even if an attempt is made to take a break during the work. In addition, it is necessary to wrap the thigh belt around the thigh at the time of wearing, and this forward bending work assisting tool has a problem that it is troublesome to wear.

When the outermost layer is composed of one elastic band covering from the lower end to the upper end, the inner layer is made of one or more elastic bands shorter than the inner layer, with the lower end being coincident with the inner layer. It is to be configured.

3 of the present invention is the muscle force assisting device of 1 or 2 of the present invention,
The two tension belts are crossed at the front of the wearer, the lower end of the tension belt pulled out from the right shoulder side is at the lower left, the lower end of the tension belt pulled out from the left shoulder side is at the lower right, It is supposed to be combined with.

4 of the present invention is the muscle force assisting device of 1, 2 or 3 of the present invention,
The shoulder support member is composed of two parts for the right shoulder and the left shoulder, each of which is formed in a substantially inverted U shape in a side view, and each of which is provided with a pair of guide rings on the back side and the front side. The tension belt is passed through the guide rings of each set on both sides.

5 of the present invention is the muscle force assisting device of 1, 2 or 3 of the present invention,
The shoulder rest member is configured such that the lower part of the vest where the right shoulder and the left shoulder are integrated is removed, and the shoulder support member is two parts located on the back side and the front side in the right shoulder side part and the left shoulder side part, respectively. A set of guide rings is provided, and the tension belt is passed through each of the guide rings of the right shoulder side and the left shoulder side.

6 of the present invention is the muscle force assisting device of 1, 2, 3, 4 or 5 of the present invention,
In order to hold the two belt-like elastic members in proximity to the back surface of the adherend, the device can be wrapped around and fixed to the body of the wearer with a holding means for holding the two belt-like elastic members. A possible separation preventing belt is attached to the two belt-like elastic members.

  According to the muscle strength assisting device of the first aspect of the present invention, the body of the care recipient who is attached to the body and located in front and lower is raised, rotated, moved, or a large-weight article is provided. When lifting and moving, the two elastic strips located on the back of the belt help raise the body that has been tilted forward, making it easy to operate and work without hurting your waist. It can be done safely. In particular, each belt-like elastic member is constituted by a belt-like base spring in the vicinity of the waist and a belt-like auxiliary spring above it, so that the bending action and the standing-up action of the corresponding body part are more efficiently assisted by each. Yes.

  During bending, the weight of the upper body is supported by the spring force that resists the bending of the belt-shaped basic spring and the belt-shaped auxiliary spring, and the action of raising the body restores the bent belt-shaped basic spring and belt-shaped auxiliary spring to a straight state. Needless to say, it will be assisted by force.

  In addition, the above two belt-like elastic members are joined to the upper end of the tension belt in which the lower end is joined to the front side of the waist belt which is fixed by wrapping the upper end of each belt-like auxiliary spring through the outer surface of the smooth surface of the shoulder support member. Therefore, when the wearer bends the body forward, the tension belt relatively and smoothly moves the outer surface of the shoulder support member to the rear side, and the upper end of the belt-like elastic member is relatively When the body is woken up, the tension belt moves relatively and smoothly on the outer surface of the shoulder support member to the front side, so that the upper end of the belt-like elastic member is relatively moved. Allow rise without stress.

  Therefore, when the body is bent forward, the belt-like elastic member does not cause a phenomenon of pulling up the waist belt with a strong force. The phenomenon of pushing down with force does not occur. Therefore, in order to avoid such a phenomenon, it is not necessary to wind a fixing belt around the thigh and to connect the lower end of the belt-like elastic member directly or indirectly thereto. In this way, it becomes possible to simplify the structure of this muscle strength assisting device, and the belt wound around the thigh is uncomfortable because it is forcibly pulled up or pushed down during the forward bending / standing operation of the body. You can also avoid the phenomenon that you think.

  As described above, the action of the tension belt and the shoulder support member smoothly performs the relative lifting and lowering operation that occurs in the belt-like elastic member during the forward bending operation and the standing up operation of the body of the wearer. As a result, the force in the up-and-down direction applied to the waist belt is reduced, but further, a fastening auxiliary belt is wound around the waist belt and tightened, so that the waist belt is fixed to the waist. The waist belt is less likely to move due to the lifting and lowering motion that occurs in the belt-like elastic member. Further, since the tightening auxiliary belt is wound from above the projecting member disposed in the central portion on the back side of the waist belt, much of the tightening force by the tightening assist belt is concentrated on the projecting member. Therefore, it can be fixed to the waist more reliably.

  According to the muscle strength assisting device 2 of the present invention, when these are attached to the body and the body is bent forward or standing, each belt-like elastic member (band-like foundation) at a site where stronger muscle strength assistance is required. Since the number of laminated elastic strips of springs or belt-like auxiliary springs is large, muscle strength assistance can be performed more efficiently.

  Of the two muscle strength assisting devices of the present invention, the innermost layer is composed of a single elastic band material covering from the lower end to the upper end, and the outer layer is made to coincide with the lower end, and the more laminated to the outer layer. In the case of a structure composed of one or more short elastic strips, as described above, the muscle support can be performed sufficiently efficiently, but the short elastic strip is positioned on the outer layer side as described above. Therefore, there is no fear that the upper end abuts on the back of the wearer and damages the back. However, in order to allow the elastic band on the outer layer side to bend approximately together with that on the inner layer side when the wearer is bent forward, the upper end side of the elastic band material on the outer layer side should not be separated from that on the inner layer side. It is necessary to adopt a configuration such as coupling with rivets or the like.

  Of the two muscle strength assisting devices of the present invention, the outermost layer is composed of a single elastic band material covering from the lower end to the upper end, and the inner layer is made to coincide with the lower end, and the inner layer is more laminated. Of course, in the case of a structure composed of one or more short elastic strips, it is possible to assist muscle strength sufficiently efficiently as described above, while the short elastic strip is positioned on the inner layer side as described above. In addition, since the upper end is located on the back side of the wearer, the periphery of the upper end is covered with a cushioning member so that it does not cause a problem of being in direct contact with the back and being damaged. In this case, it is necessary to bend the elastic band material on the outer layer side simultaneously with the bending of the elastic band material on the outer layer side. The elasticity of the inner and outer layers of each auxiliary spring Wood bonding of only the lower end of the other, the upper side is advantageous not necessary to bond.

According to the muscle strength assisting device of the third aspect of the present invention, when this is worn on the body and the body bends or stands up, the two elastic band members are located on both sides of the back of the wearer. Therefore, it is possible to avoid the problem that the muscular strength assisting action cannot be efficiently performed due to the deviation.
The two belt-like elastic members on the back side tend to be located on the side of the body by moving the back side outward when the wearer performs a forward bending action or standing action of the body. If this happens, the two belt-like elastic members will not be able to sufficiently perform the function of assisting the body's forward bending or standing movement. . However, according to the third strength assisting device of the present invention, the two tension belts are crossed at the front surface of the wearer, and the lower end of the tension belt pulled out from the right shoulder side is pulled down from the left shoulder side. Since the lower end of the tension belt is at the lower right and is to be joined to the waist belt, the two belt-like elastic members are also used when the wearer bends or stands up. They are attracted to the center side of the body, and any problem that they move to the side of the body does not occur, and it is possible to reliably perform the muscle strength assisting action.

  According to the muscular strength assisting device of the fourth aspect of the present invention, the shoulder support member is composed of two parts for the right shoulder and the left shoulder, and therefore there is an advantage that the left and right movements are slightly free. Appropriate handling is possible even when the body is slightly twisted from side to side for work reasons.

  According to the muscular strength assisting device of the fifth aspect of the present invention, the shoulder support member is configured as a member in which the lower part of the vest is deleted with one member continuous from the right shoulder to the left shoulder, and is configured integrally as a whole. Therefore, the structure is stable, and even if various operations are performed by the adherent, the action is not disturbed and the action is stabilized.

  According to the muscular strength assisting device of the present invention, the separation preventing belt provided with the holding means for holding the two belt-like elastic members is attached to the two belt-like elastic members. When the prevention belt is wrapped around the body of the wearer while holding the two belt-like elastic members by the holding means, and both ends thereof are joined, the two belts positioned on the back side of the wearer The band-shaped elastic member is not easily separated from the back side even when the adherend bends forward, and becomes a bent state that approximates the body's forward bend with the forward bending action, The burden on the lower back due to the weight of the upper body when bent forward can be reduced appropriately, and when it causes the body, the movement of the lower back and back can be appropriately assisted by the restoring force to the straight state. it can. Even if this separation prevention belt is not provided, the two belt-like elastic members are not greatly separated from the back surface of the adherend due to the action of the tension belt, but this separation prevention belt was adopted. In that case, the effect is further ensured.

  Furthermore, according to the muscle strength assisting device of the present invention, since the two belt-like elastic members are held by the holding means, the two belt-like elastic members are attached to the back side when the wearer is bent forward. The hugging means prevents movement toward the side, and the muscular strength assisting action due to the side movement can be prevented from being reduced.

Most of the pressing force is concentrated on the protruding member 3, and the waist belt 2 is strongly pressed against the back of the wearer particularly at this portion, and the waist belt 2 can be strongly attached to the waist of the wearer. It will be possible.

  Next, as shown in FIGS. 3 and 6, the waist belt 2 is attached to the lower ends of the tension belts 5 and 5 on both sides suspended from the front sides of the shoulder support members 6a and 6b for the right shoulder and the left shoulder. It is coupled to the locking tools 8 and 8 that will sometimes be located in the corresponding part on the front side. As shown in FIGS. 5 and 6, male and female hook-and-loop fasteners 5a are arranged on the outer surfaces of the lower ends of the tension belts 5 and 5 on both sides. As shown in FIGS. 5a is passed through the locking rings 8b of the locking devices 8 and 8 so as to protrude from the inside to the outside, and the portion protruding to the outside is folded upward so that the necessary tension can be obtained. After pulling, the inner part and the outer part are overlapped and joined and fixed by the hook-and-loop fasteners 5a and 5a arranged on the corresponding parts.

  Further, the separation preventing belt 7 is attached as shown in FIGS. 3 and 6 after appropriately determining the holding height position of the holding means 7c with respect to the two belt-like elastic members 1 and 1. The body is wound around a person's body, and both ends thereof are coupled and fixed by the locking ring 7a and the male and female surface fasteners 7b.

  The holding height position for the two belt-like elastic members 1 and 1 by the above-mentioned holding means 7c means that the two belt-like elastic members 1 and 1 are held close to the back of the wearer. Therefore, the holding means 7c is a height position suitable for holding the belt-like elastic members 1 and 1. Although it seems that the height position of any of the band-shaped auxiliary springs 1b and 1b constituting the band-shaped elastic members 1 and 1 or the height position of the upper portions of the band-shaped basic springs 1a and 1a is often appropriate. However, it is possible to select an appropriate height position in actual use.

  As shown in FIG. 3 and FIG. 6, the belts that are coupled to both ends of the holding means 7c are wound around the body side portion from the back of the wearer to the front side. Pull out and pass the belt portion on the other end side through the locking ring 7a at one end so that it goes out from the inside to the outside, and the end of the belt portion that goes out to the outside of the two belt-like elastic members 1, 1 After pulling so as to obtain the tension necessary to prevent separation, the end of the belt part that protrudes outward is folded back, both outer surface sides are brought into contact, and both male and female are arranged on both outer surface sides. The hook-and-loop fastener 7b is fixed by joining.

  This completes the attachment of the muscle strength assisting device of this embodiment to the body of the wearer. Since it is not necessary to attach the belt to the thigh, the wearing operation is simple.

  As described above, when the muscle strength assisting device of this embodiment is worn, the body such as a care recipient located in front of and below the body of the wearer is raised, lifted, rotated, moved, or heavy. When the articles are lifted or moved, the two band-like elastic members 1 and 1 located on the back of the articles assist in supporting the weight of the upper body of the bent body or stand up the body. Since the movement is assisted, the movement / work can be easily and safely performed without hurting the back or the lower back. In particular, each belt-like elastic member 1, 1 is constituted by the belt-like basic springs 1a, 1a near the waist of the wearer and the belt-like auxiliary springs 1b, 1b near the back of the wearer above, respectively. Thus, the bending and standing movements of the corresponding body part (back or waist) are more appropriately and efficiently assisted.

  In addition, the gravity applied to the upper body during the bending operation as shown in FIG. 3 is supported in detail by the spring force that resists the bending of the belt-shaped basic springs 1a, 1a and the belt-shaped auxiliary springs 1b, 1b. It goes without saying that the raising operation is assisted by the restoring force of the bent strip-shaped basic springs 1a, 1a and the strip-shaped auxiliary springs 1b, 1b to the linear state.

  In addition, the above-described two belt-like elastic members 1 and 1 are coupled to the fasteners 8 of the waist belt 2 through the outer surfaces of the smooth surfaces of the shoulder support members 6a and 6b at the upper ends of the belt-like auxiliary springs 1b and 1b. Since the tension belts 5 and 5 are coupled to the upper ends of the tension belts 5 and 5, when the wearer bends the body forward, the upper end sides of the tension belts 5 and 5 smoothly slide on the outer surfaces of the shoulder support members 6a and 6b. Accordingly, the upper ends of the belt-like auxiliary springs 1b and 1b can be relatively moved downward. When the body is erected, the relative rise of the upper ends of the belt-like auxiliary springs 1b and 1b is allowed without stress.

  In addition, at the time of the forward bending or standing motion of the body of the above-mentioned adherent, the lower belt-shaped basic springs 1a and 1a constituting the two belt-shaped elastic members 1 and 1 also move relatively downward or upward. However, the amount of displacement is smaller than that of the belt-like auxiliary springs 1b and 1b. It goes without saying that the relative displacement of the band-shaped basic springs 1a, 1a is also allowed by the action of the tension belts 5, 5 and the shoulder support members 6a, 6b.

  As described above, since the displacement of the two belt-like elastic members 1 and 1 is allowed, an excessive upward and downward force is applied to the waist belt 2 during the forward bending operation and standing operation of the wearer. It won't hang. Therefore, there is no need to support the force in the above-described lifting direction with the thigh belt, and the thigh belt can be omitted, and the above-described adverse effects can be eliminated. .

  On the other hand, as shown in FIG. 1 (a) and FIGS. 2 to 4, the waist belt 2 is provided with the protruding member 3 at the center part on the back side and further passing through the back side thereof. An auxiliary belt 4 is provided, and the tightening auxiliary belt 4 is wound around the body as described above, and is tightened appropriately, and at the front part of the body as described above, The waist belt 2 is fixedly pressed and fixed to the waist of the wearer, particularly at the portion of the projecting member 3, by fixing by using the retaining ring 4a and the hook-and-loop fastener 4b on the other end side. If the belt-like elastic members 1 and 1 are not properly moved up and down, even if a slightly strong force is applied to the waist belt 2, there is no problem of easily moving. Yes.

  Further, according to the muscle strength assisting device of this embodiment, when these are attached to the body and the body is bent forward or standing, the band-shaped basic springs 1a and 1a are particularly shown in FIGS. As shown in the figure, three strip-shaped spring members with different lengths are constructed by laminating from the inner layer in order from the longest, with the bottom ends aligned, making it more efficient especially at the waist where strong muscle strength assistance is required. Muscular strength assistance can be performed. In addition, as shown in FIGS. 2 to 4, the belt-shaped auxiliary springs 1b and 1b have two strip-shaped spring members having different lengths, with the lower ends aligned, and the long one as the inner layer and the short one as the outer layer. Therefore, even when strong muscle strength assistance is necessary at the back, muscle strength assistance can be appropriately performed.

  Further, according to the muscle strength assisting device of this embodiment, the separation preventing belt 7 provided with the holding means 7c for holding the two belt-like elastic members 1, 1 is attached to the two belt-like elastic members 1, 1. Therefore, as shown in FIG. 3, the separation preventing belt 7 is wrapped around the body of the adherend while holding the two belt-like elastic members 1 and 1 by the holding means 7c. As described above, the belt portion at the other end is locked to the locking ring 7a at one end, the belt portion at the other end is pulled so as to obtain a necessary tension, and then the male and female at the belt portion at the other end are pulled. If the hook-and-loop fasteners 7b are joined to each other and the locked state is fixed, the two belt-like elastic members 1 and 1 located on the back side of the wearer can bend forward by the wearer. The bent state is not easily separated from the back side of the body and approximates the body's forward bending shape with its forward bending movement. The load on the lower back due to the weight of the upper body when bent forward can be reduced appropriately, and when it causes the body, the movement of the lower back and back is properly supported by the restoring force to the straight state can do.

  The two belt-like elastic members 1 and 1 are not greatly separated from the back surface of the wearer due to the action of the tension belts 5 and 5. The effect of preventing separation from the back of the wearer is further ensured.

  The muscle strength assisting device according to the present invention involves a long-time work in a forward bending posture, or a work that repeats each posture change from a forward bending posture to an upright posture and from an upright posture to a forward bending posture, which causes back pain. The present invention can be used in each field where various operations are performed, or in the field of the manufacturing industry that manufactures it.
