Description

Movement support work clothes

The present invention operates both arms and legs in the same manner as the left and right sides or separately, and bends forward with a bow or mid-waist or sits down, then lifts the load in front of the chest or abdomen, or raises the arm in front of or overhead. The present invention relates to a work support work clothes used when continuing to work over a period of time.

At the distribution site where you lift your luggage or twist your hips to move or handle your luggage after you bend down with your forward flexion, middle hips, or sitting down, or the same posture with your forward flexion, middle hips or back muscles stretched, or your back flexed. While repeating stretching, raise the arm in front and assemble products from the product parts that flow one after another on the belt conveyor, the agricultural site where you sit down and raise your arms to plant and harvest seedlings, nursing care -Workers who work hard such as nursing care and medical care to move patients to be treated have a heavy physical burden on their arms, shoulders, hips, or legs, especially their arms, hips, and back, Fatigue easily accumulates in a short time.

To reduce such physical burden, auxiliary tools have been developed to assist the movements of the muscles of the back and legs and reduce the work burden while improving work efficiency.

For example, in Patent Document 1, the left belt and the right belt are respectively folded back from the left and right shoulders via the left and right joints located on the dorsal side of the left and right thighs, and then positioned on the back. There is disclosed a lumbar muscle force assisting tool wound around the waist in the left and right directions via the left holding part and the right holding part, respectively. This lumbar muscle assisting device is that the left and right connectors can exert the function of a moving pulley and tighten around the waist with a restoring force that tries to return the forward bending posture to generate sufficient posture restoring force. It is a thing.

Further, in Patent Document 2, the left belt and the right belt are respectively attached from the left and right shoulders to the left and right knees via four holding portions located on the back and waist, One end of the left waist belt and the right waist belt was slidably connected to the left belt and the right belt between the holding portions, and the other end was wound around the waist in the left-right direction. A lumbar muscle support device is disclosed. This lumbar muscle assist device pulls the left and right belts when it bends forward to generate tension, and the left and right waist belts also pull to increase the tightening force around the waist. Both the tension and the tightening force of the left and right waist belts are released.

Further, in Patent Document 3, there is a waist burden reducing device which is attached to the upper body and lower limbs and assists the muscles of the waist and back in a posture where the trunk is bent forward. The left shoulder, the back, the right waist, the right buttocks, And one main member that is placed through the right thigh rear part to the right knee part, and the other one that is placed through the right shoulder, the back, the left waist, the left hip, and the left thigh rear part to the left knee part. A main member, and one main member and the other main member intersect with each other at the back and are separated from each other below the intersection, and one main member is displaced to the right side part below the intersection, and the other main member A waist load reducing device with a compression avoidance function is disclosed in which the member is displaced to the left side part below the intersection. This waist load reducing device can release or restore the function of assisting the muscles of the back of the waist by a simple operation.

An operator who leans forward on his arms or legs, leans forward or sits down and then lifts a load, or raises his arms in front of him or above his head to continue working, is as simple and lightweight as possible. , I am looking for work clothes such as assistive devices and reducers that can selectively assist the muscles for the motions I want to assist. However, the conventional work clothes have a holding part and the main members intersect with each other, so one of the workers who wants to operate separately on the left and right sides or operate by twisting should be assisted. Although it is easy to assist the muscles of the body, there is a problem that it does not require assistance and it is better not to assist, because it acts on the muscle of the other body, which in turn imposes an extra muscle burden.

In addition, work clothes such as conventional assistive devices and reducers pull the belt when the waist is bent, and the belt reaction force tightens the back and the waist, but only assists the waist and does not apply to the arm. Since the burden on the arm does not change, there is a problem that a woman or an elderly person who has a weak arm strength due to the lifting motion may tire his arm in a short time.

In addition, work clothes such as conventional assisting tools and reducing tools cannot be easily removed, so once the adjustment and wearing are performed to obtain the desired motion assistance, the strength and angle of the motion assistance can be adjusted easily. I can't readjust it. Once the belt is set to be strong and worn, it is weak and difficult to readjust, and if the belt is always fastened, it tends to warp and prolong fatigue during long working hours.

It is a rear view which shows the back of another one aspect | mode of the movement assistance work clothes to which this invention is applied. It is the schematic which shows the use condition of another one aspect | mode of the movement assistance work clothes to which this invention is applied, and the graph which shows typically the correlation of the condition and reaction force.

Hereinafter, modes for carrying out the present invention will be described in detail, but the scope of the present invention is not limited to these modes.

As shown in FIG. 1, one aspect of the motion assisted work clothes 1 of the present invention is that an operator raises his or her arm in front of him or her in a posture such as forward bending, mid-waist or pucker, or a straightened back muscle. Wear it when you move your luggage or patient, or perform heavy labor such as producing or processing goods, products or crops by bending, bending, sitting down or twisting your hips It is a thing.

In the motion assisting work clothes 1, the arm assisting belt portion 10 and the waist and dorsal leg assisting belt portion 30 do not intersect each other on the left and right sides, and the deformable and planar focusing member 20 is provided at the center of the back. It is said that they are focused. The left and right arm auxiliary band portions 10 and the left and right lumbar-dorsal leg auxiliary band portions 30 are connected at their ends to the four corners of the deformable and planar focusing member 20.

The arm assisting belt portion 10 is supported by the arm supporting portions 11 of both arms so that it can be lifted up, and the arm supporting portions 11 extend over the shoulders and over the back, respectively, and a part thereof is an elastic body 10a. The arm assisting band portion 10 may have a length adjustable by having an adjuster having a length adjustable (not shown). The length of the arm assisting band part 10 may be adjusted by the adjuster 36 of the waist / dorsal leg assisting band part 30 having an adjustable length. In FIG. 1, the arm assisting band portion 10 is shown exposed to the front surface of the sleeve 17, but it may be housed inside the sleeve 17, and the front surface or the back surface of the sleeve 17 may be accommodated. It may be partially passed through the sheath 18 so that it can be slipped. The waist / back leg assisting belt portion 30 is connected to a stepping portion 31 for stepping on and supporting the soles of both feet, extends from the waist and hips to the back, and partially forms an elastic body 30a.

As shown in FIG. 1B, the deformable and planar focusing member 20 has a rectangular shape and is adjusted to be located at the center of the back. The deformable and planar focusing member 20 is formed by having an anisotropic woven fabric that extends obliquely in the chest width direction and the body axis direction rather than in the chest width direction and the body axis direction. By connecting the auxiliary belt portion 10 and the left and right lumbar-dorsal leg auxiliary belt portions 30 to both legs to the four corners, the movement of these four belt portions 10 _L , 10 _R , 30 _L , 30 _R can be performed. It is designed to deform in conjunction (see Fig. 2).

The deformable and planar focusing member 20 is not limited to a rectangular planar shape, and may be a polygonal shape, a circular shape, or an elliptical shape. Such a focusing member 20 may be composed only of an anisotropic woven fabric 21 extending obliquely in the chest width direction and the body axis direction rather than in the chest width direction and the body axis direction, such as a cushion material such as sponge, sponge or urethane foam. A pad member in which the porous material is covered with the bag-shaped fabric 21 may be used.

The woven fabric 21 has anisotropic deformability, but preferably has almost no elasticity. For example, the woven fabric 21 may be made of synthetic fiber such as polyester or nylon.

The deformable focusing member 20 is specifically configured to be deformed as shown in FIG. The woven fabric 21 forming the deformable focusing member 20 is a plain woven fabric. These woven fabrics 21 are, for example, woven fabrics or woven fabrics in which weft yarns (weft yarns) and warp yarns (warp yarns) are repeated and cross each other one by one.

In the case of a plain weave, the woven fabric 21 of the deformable bundling member 20 has a weft direction substantially parallel to the chest width direction of the worker and a warp direction substantially parallel to the body axis direction of the worker. It is arranged so that it faces in any direction.

The deformable focusing member 20 is connected to the left and right arm assisting belt portions 10 for both arms and the left and right waist and dorsal leg assisting belt portions 30 for both legs in the vicinity of the four corners, for example, by sewing. Specifically, as shown in FIG. 2 (a), the ends of the left and right arm auxiliary band portions 10 _L and 10 _R are connected to each other at a sewing portion 22 by sewing in the vicinity of both ends on the upper side which is the shoulder side. The respective ends of the left and right waist / dorsal leg auxiliary bands 30 _L and 30 _R are connected by sewing at a sewing portion 22 near both ends on the lower side, which is the waist side.

The deformable focusing member 20 is not pulled by the arm assisting band part 10 and the waist / dorsal leg assisting band part 30 as shown in FIG. 2A when the worker is not bent forward. Therefore, the weft yarns of the woven fabric 21 are oriented in the operator's body axis direction and the warp yarns are oriented in the operator's body axis direction, and as a result, the focusing member 20 is not deformed.

On the other hand, the deformable focusing member 20 is used when the worker bends forward without twisting the body to the left or right, when the left and right arms are similarly raised, or when the left and right legs are bent similarly. As shown in FIG. 2B, the left and right arm assisting belt portions 10 and the left and right waist / dorsal leg assisting belt portions 30 are equally pulled. Therefore, the weft yarns of the fabric 21 hardly extend while being oriented in the body axis direction of the worker, and the warp yarns hardly extend while being oriented in the body axis direction of the worker, and as a result, the focusing member 20 is not deformed. .

On the other hand, the deformable converging member 20 is operated when the worker separately operates the left and right and twists the body left and right, for example, left, or bends the body left and right, for example, left and bends forward. and, and when raised only one arm example the right arm, when the left leg back before the example right leg back and forth legs, as shown in FIG. 2 (c), right arm auxiliary band portion 10 _R and the left in the Koshiseashi auxiliary strip section 30 _L in strongly pulled the arm auxiliary band portion 10 _L and the right Koshiseashi auxiliary strip section 30 _R of the left not only pulled little or weakly. Therefore, the weft threads of the fabric 21 are tilted to the right and distorted, and the warp threads are tilted to the right and distorted. As a result, the deformable focusing member 20 causes the deformable bundling member 20 to sew the right arm assisting belt portion 10 and the left waist and back leg assist. It is stretched in a diagonal direction with respect to the sewn portion of the band portion 30, and accordingly, it is diagonally oriented with respect to the sewn portion of the right arm auxiliary band portion 10 and the sewn portion of the left waist / dorsal leg auxiliary band portion 30. It distorts and shrinks. Due to such deformation, the desired tensions set for the left and right arm assisting belt portions 10 and the left and right waist and dorsal leg assisting belt portions 30 are appropriately maintained in a well-balanced manner, and the arms and back are stably supported. -It will assist the waist, legs and knees.

Note that the same movement will be performed symmetrically even if the left and right movements are reversed.

On the other hand, as in the conventional work support work clothes, a series of integrated lines of the right arm auxiliary band and the left waist / dorsal leg auxiliary band are combined with the left arm auxiliary band and the right waist / dorsal auxiliary band. When crossing a series of integrated lines with the parts, when performing left and right separate movements, the strips of both lines simply slide independently at the crossing point and are not adjusted to the left and right, resulting in separate movements. The balance between the belts on both lines will be imbalanced, and it will not be possible to stably support the arms, back, waist, legs, and knees.

As shown in FIG. 3 (a), the deformable focusing member 20 is cut at four corners of the shoulder side of the upper side and the waist side of the lower side, and the left and right arm assisting belt portions are cut there. The respective end portions of 10 and the left and right lumbar-dorsal-leg auxiliary band portions 30 may be connected by a sewing portion 22. As a result, the right arm assisting band 10 _R and the left waist dorsal leg assisting band 30 _L , or the left arm assisting band 10 _L and the right waist dorsal leg assisting band 30 _R were pulled. At this time, the focusing member 20 is deformed without being twisted so much, so that the desired tension is more appropriately balanced and appropriately maintained, and more stably assists the arms, back, waist, legs and knees. There is less discomfort due to the difference between left and right assistance.

As shown in FIG. 3 (b), the deformable focusing member 20 is wound around the respective end portions of the left and right arm auxiliary band portions 10 and the respective end portions of the left and right lumbar-dorsal leg auxiliary band portions 30. It may be movably connected by a hook metal fitting 23. In this way, the left and right arm assisting belt portions 10 and the left and right waist and dorsal leg assisting belt portions 30 are naturally adjusted to the optimum angles with respect to the deformable focusing member 20 according to the physique of the worker. Since the focusing member 20 is deformed without being twisted so much, the focusing member 20 is more appropriately balanced and appropriately maintained, and the difference in left and right assistance is less uncomfortable.

Another mode of the motion assisted work clothes 1 of the present invention is, as shown in FIG. 4, when the worker is in the upright state, the first elastic cloth 41 on the outer side which is just tensioned with respect to the back and the first elastic cloth 41. It has a second elastic cloth 42 on the inside which is loosened by being somewhat longer than the first elastic cloth 41.

In this motion assisting work clothes 1, the first elastic cloth 41 and the second elastic cloth 42 that are overlapped at least in part hold the waist / dorsal leg auxiliary band portion 30 while locking the waist / dorsal leg auxiliary band portion 30. It may be connected to the waist rest portion 47 pulled to the tread portion 31 by the sewing machine and the neck portion 45 of the vest 40 connected to the arm support portion 11 by sewing. The vest 40 has a front body and a back body sewn with a shoulder portion and a side portion reinforced by a shoulder pad. Therefore, the neckline portion 47 does not lose its shape even when pulled. The second elastic cloth 42 is longer than the first elastic cloth 41 by several cm, for example, 1 to 3 cm, preferably 2 cm, and is slackened.

Further, in the waist rest portion 47, the leg assisting belt portion 37, at least a part of which is an elastic body, is connected to the stepping portion 31 via the knee winding portion 34, and together with the waist back leg assisting belt portion 30, forward bending and arm raising. As a result, the first elastic cloth 41 and the second elastic cloth 42 lock the waist / dorsal leg auxiliary band portion 30 by being pulled.

Also, when the waist rest 47 and the hem of the back body 48 of the vest 40 are connected via the surface fasteners 46 so that the position can be adjusted, the position can be easily adjusted at the time of mounting and after mounting. Therefore, the degree of assistance of the posture, auxiliary position, auxiliary angle, and auxiliary strength to be taken by the arm, waist, leg, and auxiliary strength can be adjusted easily and arbitrarily by oneself. Moreover, the first elastic cloth 41 and the second elastic cloth 42 can be adjusted, and the length of the arm assisting belt portion 10 can be adjusted.

In this movement assisting work clothes 1, the vest 40 may be the back body 48 on the back side, which also serves as the second elastic cloth 42.

The vest 40 may have a front opening 43 that can be opened and closed by a line fastener on the front side, or may have a chest belt. Furthermore, you may have the armpit fastening part 50 which extends from the front body 43 and goes to the waist support part 47 through the armpit. As a result, the action of the arm assisting belt portion 10 can be reliably transmitted to the arm support portion 11 to assist the arm, and the action of the waist / dorsal leg assisting belt portion 30 can be surely transmitted so as not to escape, so that the legs / waist / back can be prevented. Can be assisted.

It is more preferable that the first elastic fabric 41 and the second elastic fabric 42 are elastic fabrics that can selectively stretch in the body axis direction but hardly stretch in the chest width direction. These elastic fabrics include, for example, 1-way stretch fabric having elasticity in one direction of the warp direction or the weft direction, for example, satin net, and specifically, have warp knitted fabrics. That is. The warp knit fabric is a tricot, a russell, or a Milanese manufactured by using a tricot knitting machine, a Russell knitting machine, or a Milanese knitting machine. In particular, a so-called power net having a knitting structure of a Russell net, a knitting structure of polyurethane elastic yarn and polyester, and a polyurethane elastic yarn knitted straight is preferable.

In this operation-assisting work clothes 1, when the attached worker is not bent forward, for example, in the upright state, the first elastic cloth 41 does not slacken and expand as shown in FIG. The shape is just tense and the elastic function is not effective, and the second elastic cloth 42 is slackened and the elastic function is not effective.

The front body 43 of the vest 40 has a warp direction and a weft direction in the body axis direction and the chest width direction so as not to extend when the arm assisting band part 10 and the waist / dorsal leg assisting band part 30 are pulled. A plain plain weave may be used, and a woven fabric that does not extend in the body axis direction but can extend in the chest width direction, for example, a woven fabric used for the first elastic fabric 41 or the second elastic fabric 42, is used as the first elastic fabric 41. Alternatively, the direction of the second elastic cloth 42 may be arranged in the direction of the straight line.

In this motion-assisting work clothes 1, when the worker leans forward with the upper body slightly tilted, the first elastic cloth 41 stretches elastically as shown in FIG. Since the elastic cloth 42 is not pulled, the elastic cloth 42 has a shape in which the elastic function is not effective.

In this motion-assisting work clothes 1, when the worker is in a forward bending state in which the upper body is greatly tilted, as shown in FIG. 5C, the first elastic cloth 41 is elastically further extended, and with it. The second elastic cloth 42 has an elastically stretched shape.

Generally, a spring has a law of elasticity (Fook's reaction force, where F is a reaction force due to the spring, k is a spring constant (SC), and x is an extension from a natural length). The spring constant in the law) increases with the amount of elongation, and the reaction force and the amount of elongation show a non-linear correlation. This formula also holds for elastic bodies.

The reaction force F by the elastic body of the first elastic cloth 41 and the second elastic cloth 42 in the state of FIGS. 5A to 5C is as follows. In FIG. 5, the spring constant of the first elastic cloth 41 is k ₁ , and the spring constant of the second elastic cloth 42 is k _2, and the first elastic cloth 41 and the second elastic cloth 42 in FIG. F ₀ a reaction force of the sum of _the, the natural length of the first resilient fabric 41 and x _0, the reaction force of the sum in FIG (b) F _1, in a state where the first elastic cloth 41 is extended The natural length of the second elastic cloth 42 is x ₁ , the total reaction force is F ₂ in the same figure (c), and the length in a state where the first elastic cloth 41 and the second elastic cloth 42 are extended. Be x ₂ .

In FIG. 5A, the reaction force F ₀ = 0,
In the figure (b), the reaction force F ₁ = k ₁ (x ₁ -x ₀ ),
In the same figure (c), the reaction force F ₂ = k ₁ (x ₂ −x ₀ ) + k ₂ (x ₂ −x ₁ ).
It is represented by. Therefore, the reaction force F ₀ is not generated because the elastic function of the first elastic cloth 41 and the second elastic cloth 42 is not effective in the figure (a), but the first elastic cloth is not generated in the figure (b). Since only 41 has the elastic function, only the reaction force F ₁ due to that is exerted, and in FIG. 7C, the elastic function of the first elastic cloth 41 and the second elastic cloth 42 is effective, which causes the reaction. A stronger reaction force F ₂ is developed. In the lower part of the figure, a graph schematically showing the correlation between the length of the horizontal axis and the reaction force of the vertical axis is shown. As is apparent from the graph, as the body bends, the reaction force increases with a gentle inclination up to x ₁ , and when it exceeds x ₂ , the reaction force becomes an inclination and the reaction force further increases. The primary variable of the reaction force F changes at x ₁ . Therefore, the motion-assisting work clothes 1 assist a relatively light lifting operation when the operator leans slightly forward and bends a relatively heavy lifting operation when the operator leans greatly. It is possible to provide stepwise assistance depending on whether the person bends shallowly or bends deeply.

An example in which the outer first elastic fabric 41 covers the inner second elastic fabric 42 in a two-layer structure is shown as a preferred example. However, the inner first outer fabric 41 may be reversed from the inner side to the outer side. There may be three or more loose layers, for example three to five layers.

The first elastic fabric 41 and the second elastic fabric 42 may be made of the same material or different rubber elasticity.

As the operation assisting work clothes 1, a mode in which the deformable focusing member 20 is used as shown in FIGS. 1 to 3 and a mode in which the first elastic cloth 41 and the second elastic cloth 42 are used as shown in FIGS. Although and are shown separately, they may be used together.

Next, a member common to these aspects of the operation assisting work clothes 1, that is, an arm in which at least a part is an elastic body 10a, which supports the arm support portions 11 of both arms so as to be able to be lifted and extends over the shoulders and over the back. Regarding the auxiliary belt portion 10 and the waist-dorsal leg auxiliary belt portion 30 which is connected to the stepping portion 31 for stepping on and supporting the soles of both feet and extends through the waist and back respectively and at least a part of which is the elastic body 30a ,explain.

The arm support 11 may be provided on the hand 17, wrist, forearm, elbow and / or braces supporting the upper arm, gloves, and / or the sleeve 17 connected to the vest 40. The arm support 11 supports the forearm, elbow, and upper arm. The arm support portion 11 includes a wrist support tool 12 that surrounds and squeezes the wrist, a forearm elbow support tool 13 that surrounds and squeezes and supports the forearm base on the hand side of the elbow, and an upper arm root on the shoulder side of the elbow. It is composed of an upper arm elbow support 15 that surrounds and squeezes and supports it. The wrist support 12, the forearm elbow support 13, and the upper arm elbow support 15 are formed of belts and have surface-adjustable surface fasteners, for example, a surface having a hook-shaped engaging element and a loop-shaped engaging member. The surface fastener 14 including the surface having the mating elements is tightened with some play. For example, the forearm side elbow support tool 13 and the upper arm side elbow support tool 15 are connected to each other at their ends to form surface fasteners, and the wrist support tool 12 has surface ends to form surface fasteners.

When the upper arm side elbow support 15 that surrounds the elbow is connected to the arm assisting belt portion 10 in this motion assisting work clothes 1, even if the angle of the elbow in the upper arm becomes about 90 ° or more, The upper arm can be easily lifted according to the pulling of the upper arm elbow support.

In addition, in FIG. 1, the arm support portion 11 is the wrist support tool 12, the forearm side elbow support tool 13, and the upper arm side elbow support tool 15, and the example provided on the sleeve 17 is shown. The wrist support 12 and the forearm side elbow support 13 may be connected inside or outside the forearm by a connection support (not shown).

Also, instead of or in addition to the surface fastener, an adjuster capable of adjusting the length of the belt, a hook and a hook hanger, a button and a button hole, a protrusion and a protrusion locking ring, a belt and a buckle that locks the magnet, a magnet and a magnet. It may be tightened with a catch, a tightening band with a lock release function, or a locking device such as a string. The arm support portion 11 may be a wrist support tool that has gloves whose fingertips may be exposed and a glove support tool that is sewn and connected at the wrist-side root thereof (all not shown).

If the length from the arm supporting portion 11 to the focusing member 20 is shortened by adjusting the arm assisting band portion 10, the arm can be raised higher to facilitate the work. On the other hand, if the length is somewhat longer, the arm can be raised relatively lower to perform the work. Easier to do. Since the arm assisting belt portion 10 can be smoothly adjusted to an arbitrary length, the work can be interrupted / restarted and the arm height can be adjusted appropriately, quickly, easily and easily.

The positions of the first elastic cloth 41 and the second elastic cloth 42 can be adjusted by reattaching the hook-and-loop fastener or pulling or loosening the adjuster 36 (see FIGS. 1 and 4), and The length of the arm assisting band portion 10 can be adjusted simply by re-engaging and hooking the hook-and-loop fastener (not shown), and the strength of assisting the forearm and upper arm can be easily adjusted. When the arm assisting band portion 10 is pulled, the upper arm can be assisted more than the forearm, and when it is loosened, the lower arm can be assisted more than the upper arm.

The left and right forearm side elbow support tools 13 and the upper arm side elbow support tools 15 are connected to the left and right arm assisting band parts 10 by sewing, for example, while connecting the left and right arm support parts 11 so that they can be respectively lifted inside the elbow. Has been done. The left and right arm auxiliary band portions 10 reach the back over the left and right shoulders without crossing each other, and are connected to the focusing member 20. When the forearm side elbow support tool 13 and the upper arm side elbow support tool 15 are connected at their ends to each other as surface fasteners and attached to the sleeve, the forearm side and the upper arm are tightened and the surface at the elbow fossae is tightened. Preferably, the fasteners engage the sleeves.

The left and right arm auxiliary band portions 10 from the arm supporting portion 11 to the focusing member 20 may be entirely elastic bodies, but by making at least a part of the elastic bodies, the operation with the arm raised. Because of this, it can effectively assist the muscles of the forearm and upper arm. In the left and right arm auxiliary band portions 10 from the arm support portion 11 to the focusing member 20, it is preferable that a part of the arm auxiliary belt portion 10 is an elastic body from the arm to the shoulder.

As a part of the arm assisting band portion 10, an elastic body 10a, for example, a silicone rubber band, is heat-bonded to both ends of a cloth piece to form a non-elastic fiber band 10b which is another part of the arm assisting band portion 10. The elastic body 10a as a part of the arm auxiliary band portion 10 may be directly heat-sealed and / or directly bonded to the fiber band 10b which is another part of the arm auxiliary band portion 10. It may be sewn. The heat welding is, for example, to tear a silicone rubber band in the thickness direction, sandwich a piece of cloth or a fiber band between them, and heat-bond it by heating.

The material of the elastic body 10a is, for example, synthetic rubber such as butadiene rubber, butyl rubber, styrene-butadiene rubber, ethylene-propylene rubber, ethylene-propylene-diene rubber, nitrile rubber, chloroprene rubber, fluororubber, urethane rubber, in addition to silicone rubber. Examples include rubber and natural rubber. Natural rubber does not cause any problems when used in a room temperature environment such as room temperature, but it has temperature dependency. Therefore, it is preferable to use synthetic rubber when used in a high temperature and high humidity environment or a low temperature environment. Among them, silicone rubber is more preferable because it has excellent heat resistance, its physical properties hardly change from low temperature to high temperature, allergic symptoms do not occur, its surface tension is small, and it is easy to slide. The elastic body 10a may be made of a belt-shaped synthetic rubber or natural rubber, and an elastic material of natural rubber or synthetic rubber (for example, polyurethane) is woven into a string woven with a thread such as polyester or rayon. So-called woven rubber may be used. It is even more preferable that the elastic body 10a is a flat ribbon-shaped, columnar, or string-shaped silicone rubber strip.

In addition, the action-assisting work clothes 1 is made of a rubber having a long durability, which is not dependent on the environment, such as silicone rubber, in which the elastic body 10a of the arm assisting band portion 10 does not change its elastic characteristics with temperature and humidity. Even in a hot and humid environment such as in the summer or a boiling treatment plant, or in a low temperature environment such as a refrigerating room or a freezer warehouse, you are not affected by the surrounding environment and its changes and fluctuations, and you do not feel allergic・ Can assist movement without impairing health. Silicone rubber, in particular, does not cause health problems even if it comes into direct contact with the wearer's skin, is easy to be processed to operate smoothly, has high physical strength and chemical strength, does not easily break, and maintains its characteristics. You can

The elastic body 10a may be any rubber in the form of a strip, a column or a string, and is made by connecting a single rubber in series or bundling in parallel, arranging or stacking, or connecting a plurality of rubbers in series. It may be.

The elastic body 10a does not obstruct the operation at a slightly mild operation that does not need the assistance because the worker can fully work by himself / herself, and is a heavy work that is overloaded and requires a relatively large operation. It is preferable that the arm assisting band part 10 and / or the lumbar / dorsal leg assisting band part 30 be exerted an assisting effect when largely pulled.

As another preferable example of the elastic body in which the reaction force and the elongation amount show a non-linear correlation, as a material, a degree of cross-linking, a thickness, a width, a structure such as a thickness, or a combination thereof, it is possible to obtain a high An elastic flat band, columnar or string-shaped rubber band, for example, a high elastic silicone rubber band and a slightly slack fiber inelastic limiter string are juxtaposed in the same manner, and the material, degree of crosslinking, thickness, width , A structure such as thickness, or a low-elasticity flat belt-shaped, columnar, or string-shaped rubber band, for example, a low-elasticity silicone rubber band, which is adjusted by adjusting any combination thereof, is heated in the same manner as described above. A single piece or a plurality of pieces may be connected in series by welding and / or sewing. You can connect them alternately. As a result, when the elastic body stretches, the low-elasticity rubber strip first stretches, but if it stretches too much, it can no longer be stretched by the non-elastic limiter string, and the high-elasticity rubber strip stretches and becomes the threshold value. And exhibits strong stretchability. Therefore, when lifting a light load below the threshold, it is relatively lightly assisted by a rubber band with low elasticity, but when lifting a heavy load above the threshold, the elastic body inevitably extends excessively. Accordingly, the operation is further strongly assisted by the highly elastic rubber band. The material, the degree of crosslinking, the thickness, the width, and the thickness may be changed stepwise or gradually so that the reaction force and the elongation amount show a non-linear correlation. For example, the nonlinearity can be exhibited by gradually or gradually increasing or decreasing the thickness, width, and thickness from one end to the other end of the elastic body.

The arm auxiliary band portion 10 is made of various fibers such as natural fibers and chemical fibers except for the elastic body 10a, and has a width of 5 to 45 mm, preferably 10 to 38 mm, and more preferably 25 mm. It consists of If it is too thin, it will bite into the body and feel pain, and if it is too thick, friction with the body and innerwear and movement support work clothes 1 will be large, making it difficult to slide and not being able to provide sufficient movement assistance. I will end up. Examples of materials for such fibers include polyamide resins such as slippery nylon, fluororesins, and silicone resins.

In the motion-assisting work clothes 1, since the pair of arm assisting belts 10 that individually support both arms independently assist the operations of the forearms and upper arms of both arms, not only the operation on the front side but also diagonally forward and left and right. Even complicated movements on the side can be assisted. In addition, the motion assisting work clothes 1 may be ones that adjust the assisting position, assisting angle, and assisting strength separately by the pair of left and right arm assisting belt portions 10 according to the work content.

The motion support work clothes 1 may be mounted on the exterior or inside of coveralls, uniforms, and lab coats.

Because the arm assisting band 10 bends from the arm side to the back over the shoulder, strong friction is likely to occur between the body and the arm assisting band 10 such as innerwear. Therefore, a shoulder pad 44 made of fluororesin or silicone resin having a small surface tension is attached to clothes such as innerwear so that the friction coefficient is reduced and the arm assisting band portion 10 can easily slide on the shoulder. Alternatively, it may be sewn. The sheath 18 may be used instead of or together with the shoulder pad 44. Further, instead of the shoulder pad 44, a tubular portion or a loop such as a flat tube or a cylinder formed of a resin cloth sewn to a shoulder opening inside the vest 40 or attached with hook and loop fasteners may be used. (Not shown). It is preferable that the sheath 18 and the tubular portion are made of a slippery resin, for example, a polyamide resin such as nylon, a fluororesin, or a silicone resin.

Also, the arm assisting band portion 10 may be coated with a fluororesin coating or a silicone resin so that it can slide easily.

On the other hand, as shown in FIG. 1, the left and right lumbar-dorsal-leg auxiliary bands 30 extend from the stepping part 31 through the knees, thighs, and waist to the back. The waist / dorsal leg auxiliary band portion 30 includes a knee winding portion that surrounds the knee and / or the upper and lower portions thereof or that can be opened and closed, and a stepping portion 31.

The stepping part 31 is to be stepped on the sole of the foot, and serves as the starting point on the foot side of the waist / dorsal leg assisting belt part 30, and is fixed to the sole of the foot so that it is supported by the bottom of the foot and not dragged. The stepping part 31 is composed of a lower ring part 32 that comes into contact with the sole of the foot and a below-knee ring part 33 that extends from there to below the knee. A knee encircling part 34, which is a below-knee annular part 34a and an above-knee annular part 34b that are connected to and surround the below-knee region, is sewn at a position behind the knee in the middle of the waist / dorsal leg auxiliary band part 30. The below-the-knee annular portion 34a surrounds the below-the-knee region in a belt shape, and is closed in front of the knee by a line fastener so as to be able to open forward. The above-the-knee annular portion 34b surrounds the above-the-knee in a belt shape and is openably and closably closed by a hook-and-loop fastener in front of the knee. The shin may be provided with an adjuster or a hook-and-loop fastener (not shown) capable of adjusting the length of the stepping portion 31 on the shin as necessary.

In the motion assisting work clothes 1, when the knee winding portion is connected to the waist / dorsal leg assisting belt portion 30, the knee is held at the upper and lower parts of the kneecap to assist and the bending and stretching of the knee are facilitated. Become.

The stepping part 31 is sewn and connected to the lower back ankle part 34a to the waist back leg auxiliary band part extending from the back of the knee and the buttocks to the back through the waist.

When the length from the stepping part 31 to the focusing member 20 is shortened by the adjuster 36, the lumbar-dorsal-leg assisting belt portion 30 makes it easier to erect the back and enhances the assistance when the back is bent or bent. On the other hand, a little longer will weaken the augmentation of the assistance when the back is bent greatly or bends low, but on the other hand, the assistance for light work when the back is bent slightly or bends slightly. Facilitates continuous work for a long time. Since the length of the waist / dorsal leg auxiliary band 30 is smoothly adjusted, the work can be interrupted / restarted and the waist / back / knee assistance level can be adjusted quickly, easily and easily.

By using at least a part of the left and right waist / dorsal leg auxiliary band portions 30 from the stepping portion 31 to the bundling member 20 as the elastic body 30a, the baggage can be lifted or left and right while leaning forward or in the middle waist, or in the posture of a pouch. It can effectively assist the muscles of the knees, hips, and back for movements such as moving to. It is preferable that the left and right waist / dorsal leg auxiliary band portions 30 from the stepping portion 31 to the focusing member 20 are partially elastic bodies 30a from the buttocks to the thighs. Such an elastic body 30a may have the same material and structure as the elastic body 10a of the arm auxiliary band portion 10.

With this configuration, not only bending down but also bending the knees and flexing the posture, pulls the waist / dorsal leg support band 30 to assist not only the legs / waist but also the entire back.

Since the arm assisting band part 10 and the waist / dorsal leg assisting band part 30 are bundled by the bundling member 20, they assist each other's arm and back / waist / leg. Especially, since the motions of both knees, hips, and back are assisted separately or individually or in cooperation, complicated motions such as bending and stretching motions of arms and legs, waist and back, and vertical motions and twisting motions are performed. Even if it is, it can certainly assist.

The waist / back leg assisting belt portion 30 is likely to cause strong friction between the body or clothing such as innerwear at the buttocks or thighs. Therefore, in order to reduce the coefficient of friction, the waist-dorsal-leg auxiliary band 30 is passed through a sheath 35 made of a fluororesin or a silicone resin so that the waist-dorsal leg assisting band 30 is easily slid on the buttocks or thighs so that the operation is smooth. Good.

♪ The movement-assisting work clothes 1 are comfortable because they are made of a flexible material. In addition, since it is washable, it is hygienic.

The motion-assisting work clothes 1 having an aggregate member as shown in FIG. 1 and having a first elastic cloth 41 and a second elastic cloth 42 as shown in FIG. 5 are mounted and used as follows. The operation assisting work clothes 1 will be described by taking as an example the case where the operation assisting work clothes 1 is lifted to a height around the abdomen or the chest or the manual work is continued at that height.

First, the worker puts on the vest 40 of the motion support work clothes 1, puts both arms through the sleeves 17, and closes the line fastener of the vest 40. Next, the lower ring portion 32 of the stepping part 31 is stepped on the sole. The below-knee annulus 34a is wrapped below the knee in a belt shape and its line fastener is closed in front of the knee. The above-the-knee annular portion 34b is wrapped around the knee in a belt shape, its surface fastener is closed in front of the knee, and the knee is wrapped by the knee winding portion. An adjuster (not shown) capable of adjusting the length of the stepping part 31 to the below-knee annular part 34a is adjusted to such a degree that it is not tight. Then, when the mounted worker is in an upright state in which he or she is not bent forward, the first elastic cloth 41 does not slacken and does not stretch, but is in a shape in which the elastic function is not effective and the second elastic cloth 42 remains slack. However, the lengths of the left and right lumbar-dorsal leg auxiliary band portions 30 are appropriately adjusted by the adjusters so that the second elastic cloth 42 has a shape in which the elastic elastic function is effective in the forward bending state. After that, the wrist support 12, the forearm side elbow support 13, and the upper arm side elbow support 15 are adjusted with the adjusters 36, respectively, and both arms are tightened, and the arms together with the arm support 11 are lifted to a height about the front of the belly or chest. The length of the waist-back leg assisting belt portion 30 is set so that the arm is assisted at a desired assisting position, assisting angle and assisting strength for the arm, especially the forearm and the upper arm, when the hand is continued at that height. The final adjustment is made with the adjuster 36 whose height is adjustable. Finally, put on the shoes and the wearing is completed.

If necessary, readjustment may be made with the adjuster 36 or the hook-and-loop fastener 46 between the hem of the back body 48 of the vest 40 and the waist rest 47. Even after the final adjustment, the degree can be readjusted arbitrarily, so when walking from the work site or moving to another floor with stairs or ladders, etc. When the band 30 is appropriately released and the work site is returned to, the arm auxiliary band 10 and the waist / dorsal leg auxiliary band 30 can be freely readjusted again.

Normally, if you use a conventional auxiliary tool that is difficult to readjust once adjusted, physical and mental fatigue will accumulate, but this work support work clothes 1 allows you to freely adjust and release the degree of assistance at any time. It's easy to get tired because you can.

It is to be noted that the example in which the operation assisting work clothes 1 having the aggregation member as shown in FIG. 1 and the first elastic cloth 41 and the second elastic cloth 42 as shown in FIG. When the motion-assisting work clothes 1 is worn, it can be worn in the same manner.

While this work support work clothes 1 can assist in postures such as a pouch, it can also fully assist in dangerous postures where it is easy to hurt the lower back by bending and lifting only the hips.

Next, as to how to use the motion-assisting work clothes 1 having the aggregate member as shown in FIG. 1 and the first elastic cloth 41 and the second elastic cloth 42 as shown in FIG. 4, as shown in FIGS. An explanation will be given by taking one of the operation states of c) as an example.

As shown in FIG. 5 (a), in the upright state in which nothing is held, the arm assisting belt part 10 and the waist / dorsal leg assisting belt part 30 have a natural length and are not stretched or stretched. Also, the first elastic fabric 41 has a natural length and is just tense, but is not stretched without being pulled, and the second elastic fabric 42 is somewhat longer than the first elastic fabric 41. As a result, it is slack (see FIG. 4A).

As shown in Fig. 5 (b), use it for light work such as lifting both hands and legs in the same way and lifting a light luggage or product (not shown) with both hands to a height around the front of your chest or abdomen. In this case, if the upper body is tilted slightly and both legs are slightly bent, and the body is slightly bent forward or slightly mid-waist, by leaning the weight of the luggage and leaning the upper body or bending both legs, the arm assist band 10 and the waist are bent. The back leg auxiliary band portion 30 and the first elastic cloth 41 are pulled to the left and right symmetrically to some extent, and the first elastic cloth 41 is pulled to some extent in the body axis direction to be stretched to some extent. The second elastic fabric 42 is relaxed to some extent and becomes tense, but is not stretched or stretched.

The arm assisting belt part 10 is pulled up by the arm assisting members of both arms and slides on the shoulders, while the elastic body 10a of a part of the arm assisting part 10 stretches slightly while accompanied by elastic repulsion. Then, the biceps of both arms are assisted by the elastic repulsion of the arm assisting member. As a result, the restoring force of the elastic body of the arm assisting band portion 10 assists the arm in preventing it from going down and going up.

Also, the lumbar-dorsal-leg auxiliary band 30 extends somewhat while being elastically repulsed by a part of the elastic body 30a. Then, the muscles of both legs, particularly the gluteus maximus and the hamstrings, are assisted by the elastic repulsion of the lumbar-dorsal leg assisting band portion 30. Further, the first elastic fabric 41 stretches somewhat while being elastically repulsed by the elastic function. Then, the waist and back muscles, particularly the erector spinal muscles, are assisted by the elastic repulsion of the first elastic fabric 41. As a result, the legs, waist, back, and knees are assisted so that the elastic force of the waist / dorsal leg assisting band portion 30 and the first elastic cloth 41 returns to the standing posture from the forward bending or the middle waist posture. .

At this time, the left and right arm auxiliary band parts 10 and the left and right waist / dorsal leg auxiliary band parts 30 are pulled equally. Therefore, the weft yarns of the fabric 21 of the bundling member 20 hardly extend while being oriented in the body axis direction of the worker, and the warp yarns hardly extend while being oriented in the body axis direction of the worker, and as a result, the bundling member 20 Does not deform, so that the arm assisting band part 10 and the lumbar / dorsal leg assisting band part 30 are evenly balanced on the left and right (see FIG. 2B).

After that, when the worker operates separately on the left and right, when twisting the body to the left or right, when raising or extending one of the left and right arms, or when extending both legs back and forth, The deformable focusing member 20 is distorted and stretched in one diagonal direction, and accordingly, distorted and contracted in the other diagonal direction. As a result, the difference between the left and right tensions of the arm assisting belt portion 10 and the waist / dorsal leg assisting belt portion 30 is dispersed in a well-balanced manner, and one arm, leg, back, or waist on one side requiring assistance can be operated more stably. It can assist (see FIG. 2 (c)).

In this way, support the lifting operation loosely.

As shown in Fig. 5 (c), use it for heavy work such as lifting heavy luggage, product or patient (not shown) to the height of chest or abdomen while moving both arms and legs in the same manner. In this case, when the upper body is greatly tilted and both legs are considerably bent, and if the user leans forward and bends or has a posture of mid-waist or ponders, the weight of the luggage or the like and the upper body is tilted or both legs are bent, whereby the arm assisting belt portion 10 is formed. And the lumbar-dorsal-leg assisting belt portion 30 are strongly pulled symmetrically, and the first elastic cloth 41 and the second elastic cloth 42 are strongly pulled in the body axis direction and further stretched.

At this time, the arm assisting belt portion 10 further extends while accompanied by elastic repulsion. Then, the biceps of both arms are further strongly assisted by the elastic repulsion of the arm assisting member. The arms are even more strongly assisted so that they can go up without lowering.

Also, the waist / dorsal legs auxiliary band 30 further extends while being accompanied by elastic repulsion. Then, the gluteus maximus muscles and hamstrings of both legs are further strongly assisted by the elastic repulsion of the lumbar / dorsal leg assisting band portion 30. In addition to that, the first elastic fabric 41 and the second elastic fabric 42 are strongly pulled in the body axis direction and further stretch. Then, the waist and back muscles, particularly the erector spinal muscles, are further strongly assisted by the elastic repulsion between the first elastic cloth 41 and the second elastic cloth 42. As a result, the legs, hips, back, and knees are more strongly assisted to return from the forward bending, mid-waist, and pouch-back postures to the standing posture.

After that, when the worker twists the body, raises or extends only one arm, or spreads it around both legs, the deformable focusing member 20 is distorted in one diagonal direction and further stretched. As a result, it is distorted in the other diagonal direction and further contracted. As a result, the difference between the left and right tensions of the arm assisting belt portion 10 and the waist / dorsal leg assisting belt portion 30 is dispersed in a well-balanced manner, and one arm, leg, back, or waist on one side requiring assistance can be operated more stably. It can assist (see FIG. 2 (c)).

Using this motion support work clothes 1 increases the assisting force for lifting the luggage on the floor to the front of your chest. The amount of increase is several kg to several tens of kg. Muscle activity during the lifting motion is reduced by 40 to 50% in the biceps brachii and the erector spinae muscle.

As shown in FIGS. 5 (b) and (c), when the arms are to be kept in a lifted state in order to work at a height around the front of the belly, when the arms are lowered due to the weight of the luggage, The arm assisting belt portion 10 and the waist / dorsal leg assisting belt portion 30 of the motion assisting work clothes 1 extend. Then, the restoring force of the elastic body assists the arm to return to the lifted posture and the bent back. As a result, it is possible to reduce the force for working while lifting the luggage and the like.

At this time, in the motion assisting work clothes 1, the arm assisting belt portion 10 strongly supports the forearm rather than the upper arm, and as shown by an arrow A (see FIG. 1), the arm contacting portion of the forearm side elbow support 13 is used as a fulcrum. The forearm-side elbow support 13 and the wrist support 12 are pulled up, which mainly assists the lifting operation of the forearm. Secondarily, it assists the lifting motion of the upper arm. At the same time, it assists the motion of extending back bending.

On the other hand, when the arm is to be lifted in order to carry luggage at the chest, shoulders, face height, or overhead, the arm assisting belt portion 10 strongly supports the upper arm rather than the forearm. As a result of being pulled up with the arm contact portion of the upper arm side elbow support 15 as a fulcrum as shown by arrow B, as a result, it mainly assists the lifting operation of the upper arm, and the forearm side elbow support 13 and the wrist support 12 are connected to the forearm. The arm contact portion of the side elbow support 13 is pulled up with the fulcrum as a fulcrum to assist the lifting operation of the forearm secondarily. At the same time, it assists the motion of extending the back bending.

When only one arm is lowered, one of the left and right arm auxiliary band portions 10 is tense and the elastic body 10a of only one of them is stretched, and as a result, the desired arm lifting posture is restored even if both arms perform different actions. To be assisted.

When the worker releases the luggage, the elastic repulsion is released and the original shape is restored, as shown in Fig. 5 (a).

In this way, by using the motion assisting work clothes 1, the arm assisting band part 10 and the waist / dorsal leg assisting band part 30 can synergistically assist the motions of the arms, waist, back, legs and knees.
