Description

  TECHNICAL FIELD The present invention relates to a clothing-type work aid that can assist in work involving bending and stretching of the waist and back, such as agricultural work, nursing care, cargo handling work in factories, and moving and transporting work.

In recent years, as the number of young people engaged in work decreases, the age of workers tends to increase. In particular, agricultural workers are aging and the burden of agricultural work is increasing. Workers are also aging at work sites such as factories. Agricultural work, cargo handling work, and nursing care involving these forward bending postures place a heavy burden on the legs and hips.
Therefore, in the related art, various work assist suits aiming to reduce the burden on the worker are known.

First, a corset-type assisting device mainly for tightening the body is known.
For example, as shown in FIG. 9A, a corset-type assisting device disclosed in Japanese Patent Application Laid-Open No. H10-127729 is a health belt provided with a protruding member for stimulating a pot or the like inside the belt. The waist is fixed around the waist with a belt.
In addition, for example, a corset-type assisting tool disclosed in Japanese Patent Application Laid-Open No. 2003-047625 has a convex lumbar corrector arranged near the center of a lumbar belt main body as shown in FIG. 9B. Yes, the waist is fixed straight to reduce the burden on the spine and lumbar spine.

Secondly, a clothing-type assisting device for assisting a work operation in which an elastic body is incorporated is known.
For example, as shown in FIG. 10A, a back pain protector disclosed in Japanese Patent Application Laid-Open No. 2004-283423 has a waist protector which is an elastic body extending from the rear surface of a corset type attachment band 1 ′ that fixes the entire waist to the entire back. A plate 1 is provided. The waist protect plate 1 bends when it is bent, and the elastic force of the waist protect plate 1 is applied to support the movement of the worker when performing an upright operation from the bent position.

  Further, for example, a waist-proof band disclosed in Japanese Patent Application Laid-Open No. 52-137185 is one in which a leaf spring 7 is incorporated on the back of a corset-type garment as shown in FIG. When the plate spring 7 is bent in the bent position, the elastic force of the plate spring 7 is applied to support the movement of the worker when performing the operation of standing upright from the bent position.

  Further, an elastic body arranged on the side of the waist is also known. For example, as shown in FIG. 11, a back pain prevention supporter disclosed in Japanese Patent Application Laid-Open No. 2012-179347 is configured to connect a plurality of connecting belt pieces and wrap around the waist. The leaf spring is located at The elastic body 3 bends when the worker is in a bent posture, and the elastic force of the elastic body 3 is applied to support the movement of the worker when performing an operation of standing upright from the bent posture. Has become.

Thirdly, there is known a so-called power assist suit that more positively assists work with an actuator such as a motor.
For example, as shown in FIG. 12, the back muscle movement assisting device disclosed in Japanese Patent Application Laid-Open No. 2015-39414 connects a supporter wrapped around the waist and a supporter wrapped around the shoulder with an actuator, and the actuator is electrically driven. It exerts power mechanically. When an operator performs an operation of standing upright from a bent posture, an actuator is activated to apply a mechanical force to support the movement of the operator. In recent years, some feet have also been equipped with mechanical elements, and the overall weight has been mechanically supported not by the operator.

  Although the various work assistance suits in the above-mentioned conventional technology can be expected to have a certain effect in preventing back pain, there are problems to be improved.

  The corset-type assisting tool disclosed in Patent Literatures 1 and 2 has a problem that the work load itself cannot be assisted. Conventional corset-type assistive devices that do not incorporate elastic bodies or actuators have the effect of tightening the body itself, which prevents accidents such as lumbar displacement and spine displacement. It is not something that can assist a worker with weak muscle strength. That is, all the forces required for the work depend on the muscular strength of the worker, and it is impossible to reduce the work load of a worker with weak muscular strength such as an elderly person or a woman.

  Next, the power assist suit shown in Patent Literature 6 is capable of exerting a large mechanical force, but is a large-scale device, cannot be used regularly in farm work and nursing care, and is expensive. It is not suitable for use in farm work or nursing care where low cost is required. In addition, the mounting itself requires a great deal of labor, and it is impossible for an elderly person or the like to mount it.

  Next, the assisting tools disclosed in Patent Documents 3 to 5 cannot assist movement such as bending, twisting, or rotating on the body side. Since the elastic body is incorporated, the work load can be reduced only in a direction in which the elastic force of the elastic body can work. Since the body was not incorporated, it could not cope with movements such as bending, twisting and rotating on the body side. Due to the structure of the human body, the trunk has a "chest" wrapped in ribs, a "waist" with a lumbar spine between the ribs and the lumbar bone, and a "lumbar" with a lumbar bone. Here, the conventional assisting device incorporating the elastic body is arranged only on the “waist” or “back”, and there is no one arranged on the “chest” side or the “waist” side. However, as in Patent Document 3, when the entire back is covered along the back muscles, it is arranged on the back of the "chest" and the back of the "waist", but this is along the midline of the body. Only crouching and upright movements can be supported. Farmer care services require movements such as bending, twisting, and rotating on the side of the body, and support for bending and twisting on the sides of the “chest” and “waist”. Conventional technology solves this problem. Nothing was done.

  Accordingly, the present invention provides support for the "lumbar" and "waist" backside supports, as well as the "chest" and "waist" sides, to support movement loads such as bending, twisting, and rotating on the body side. It is an object of the present invention to provide a “work assist suit” that can reduce the amount of work.

  In order to solve the above problems, the present invention has the following configurations. The components described below can be adopted in any combination as much as possible. In addition, aspects or technical features of the present invention are not limited to those described below, but are described in the entire specification and drawings, or based on the invention ideas that can be understood by those skilled in the art from the descriptions. It should be understood that it is recognized on the basis of.

The work assistance suit of the present invention has a work clothing main body portion that covers at least the waist from the armpit of the worker to the waist, and an elastic body arranged along the body side from the vicinity of the armpit to the vicinity of the waist of the work clothing body. A work support suit that includes a body-side support elastic body that is a body and supports a body-side motion of the worker.
For example, the work support suit may be finished in a so-called “vest” without a sleeve, may be finished in a so-called “jacket” with sleeves, or may be finished in a so-called “belly band”.
With the above-described configuration, the body-side supporting elastic body, which has not been conventionally provided, allows the worker to support body-side operations such as body-side bending, twisting, and turning simply by wearing the work assistance suit of the present invention. be able to. It is widely useful for work involving body movements, such as agricultural work, nursing care services, factory cargo handling, and moving and transporting work.

Here, as an example of the body-side supporting elastic body, an elastic body in a bending direction can be obtained, and for example, a leaf spring structure can be used.
Various leaf spring structures can be employed. For example, a flat plate of a tough metal or a coil may be used. In the case of a coil shape, it is preferable to compress it in the thickness direction so as not to have a thickness. Alternatively, each of the ring plates may be a flexible ring plate, and a plurality of the ring plates may be stacked one on another while displacing a plurality of the ring plates, and connected by means such as crimping, welding, or bonding. While a strong elastic force similar to that of a coiled spring can be obtained, the thickness can be reduced to a thickness that is thin and does not differ from a flat plate spring.

  Here, it is possible to provide a structure in which the work clothing main body further includes one or more elastic bodies for waist support, which are one or more elastic bodies arranged in the vertical direction on the back of the waist. For example, there is one in which a plurality of elastic members for supporting the waist are provided near the back of the waist along the vertical direction, and are arranged in a circular shape at intervals. Since the elastic body is arranged along the vicinity of the back muscle, the movement of the waist and the back muscle of the worker can be assisted.

Next, as a further contrivance, in the work assistance suit of the present invention, in addition to the above-described configuration, the work clothes main body portion has a waistcoat-type or sleeve-type shape that covers at least a part of an operator's scapula. Is a separate or integrated work clothing scapula portion, an upper connector provided on a part of the back of the work clothing scapula portion near the scapula, and a waist back or waist of the worker's pants. A part of the side surface, or a lower connector provided on a part of the waist back or the side of the waist of the work clothing main body part, and an elastic body connected to the upper connector and the lower connector and attached therebetween. It is also possible to adopt a structure having a certain elastic cord for supporting the back muscles.
Briefly, the work clothing scapula portion includes the top of a vest-type garment and the top of sleeved garment. The work clothing shoulder blade portion may be integrated with the work clothing main body portion or may be a separate type. In the case of the separate type, the working clothing main body portion and the working clothing shoulder blade portion may be vertically separated, or may be an overlapping one (that is, a layered state).

  With the above configuration, the elastic cord for supporting the back muscles is arranged between the vicinity of the scapula which does not directly contribute to the movement of the waist and the back muscles and a part of the back of the waist or the side of the waist. With the power of the shoulder and trapezius muscle that does not directly contribute to the movement of the back and back muscles, the movement of the lumbar and back muscles of the worker can be supported.

According to the work-assisting suit of the present invention, the worker only needs to wear the work-assisting suit of the present invention by using the elastic body for body-side support, which has not been conventionally provided. It can support body-side movements. In addition, it is possible to support the movement of the waist and the back muscles of the worker.
For example, a type worn like a vest protects the body from the outside world, can adjust the body temperature, and can tighten the body to protect the body from the load. With a waistcoat type, the arm can be moved easily, so there is no hindrance to work.
It can be widely used for operations involving operations such as farm work, nursing care service, factory cargo handling, moving and carrying work.

  Hereinafter, with reference to the drawings, embodiments of the work assistance suit of the present invention and the work assistance suit of the present invention will be described. However, it goes without saying that the scope of the present invention is not limited to those shown in the following examples.

  The work assistance suit of the present invention has various variations such as a vest type and a short sleeve type, but the vest type will be described below as an example.

FIG. 1 is a diagram schematically illustrating a configuration example of a work assistance suit 100 according to the first embodiment of the present invention.
FIG. 1A is a view from the front, slightly oblique, and FIG. 1B is a view from the back, slightly oblique.
As shown in FIG. 1, a work assistance suit 100 according to the first embodiment includes a work clothing main body 110, a body-side support elastic body 120, and a waist support elastic body 130.

In this configuration example, the work assistance suit 100 is a so-called waistcoat-type example.
The material of the work assistance suit 100 is not particularly limited, but is preferably a material that is durable, has air permeability, and has a water-repellent surface.

The work clothing main body portion 110 is a portion of the work assistance suit 100 that covers at least the waist and waist around the worker from the chest. Here, since the entire work assistance suit 100 is a vest type, the work clothing main body portion 110 has a vest shape.
A zipper is attached to the front of the work clothing main body portion 110, and the zipper is closed and attached. However, a method of fastening with a button is also possible.

  The work clothing main body 110 includes a main body cloth 111, a body-side elastic sheath 112, a waist elastic sheath 113, a connector 114 for preventing slippage, and a back pocket 115 around the neck.

  The body cloth portion 111 is a waistcoat-shaped body.

  The body-side elastic body sheath 112 is a sheath arranged along the body side from the vicinity of the armpit to the vicinity of the waist of the work clothing main body portion 110, a cavity is provided therein, and the body-side support elastic body 120 is incorporated. It has become something. The body-side elastic body sheaths 112 are provided on both sides of the left body side and the right body side.

  The waist elastic body sheath 113 is a sheath disposed in the vertical direction on the back of the waist of the work clothing main body portion 110, has a cavity therein, and has the waist support elastic body 130 built therein. In this configuration example, four are provided on the back of the waist.

  The slip-up preventing connector 114 is provided near the skirt of the work clothing main body portion 110, and prevents the work clothing main body portion 110 from being shifted due to movement during work or the like. In this configuration example, the slip-up preventing connector 114 is a string loop, and as shown in FIG. 2, the slip-up preventing connector 114 is hooked on a button 201 provided on the pants, so that the pants and the work clothing main body portion 110 are hooked. Are connected so that the working clothing main body 110 does not move upward.

  The neck back pocket 115 is a pocket provided at a position in contact with the back of the worker's neck (more precisely, near the upper part of the back). A refrigerant or a heat medium can be mounted in the back pocket 115 of the neck. When working outdoors, a refrigerant or heat medium may be attached to control the body temperature in summer or winter.However, in order to obtain the effect of the refrigerant or heat medium effectively, pockets should be placed near the neck to make it easier to abut. Is provided.

Next, the body-side support elastic body 120 will be described.
The body-side supporting elastic body 120 is an elastic body, and generates an elastic force by bending. The work clothing main body 110 is arranged along the body side from the vicinity of the armpit to the vicinity of the waist. In this configuration example, they are inserted and disposed in the body-side elastic body sheaths 112 on both the left and right sides.
The upper part of the body-side support elastic body 120 is near the armpit of the work clothing main body 110, and the upper part of the waist support elastic body 130, which will be described later, is the back of the waist of the work clothing main body 110. This means that the upper part of the upper part 120 is extended to a higher position.

FIG. 3 is an example of the body-side support elastic body 120.
The structure of the body-side supporting elastic body 120 may be any as long as it generates an elastic force by bending. For example, the following example is available.

  The example shown in FIG. 3A is a leaf spring formed by forming a simple metal plate into a strip shape. In the case of such a leaf spring, it is easy to bend in a direction perpendicular to the plane of the flat plate (that is, in a bending direction to the body side in the mounted state), and it is easy to obtain an elastic force. Elastic force is also obtained in the twisting direction (that is, the direction in which the body side is twisted or rotated in the worn state). However, it is relatively hard to bend in the horizontal direction (that is, the direction of bending and warping of the back in the mounted state) on the plane of the flat plate.

  The example shown in FIG. 3B is a coil spring. In the case of such a coil spring, it is easy to bend in any direction of 360 degrees, and elasticity is easily obtained. That is, in the mounted state, the elastic force can be obtained in any of the bending to the left and right of the body side, the twist and the rotation of the body side, and the bending and warping of the back. However, since it has a cylindrical shape in a horizontal section, the thickness slightly increases.

  The example shown in FIG. 3C is an example of an elastic body in which a large number of flexible ring-shaped plate pieces are stacked while being displaced, and are arranged and connected in one direction. This is not a continuous line like a coil, but since a number of flexible ring plate pieces are arranged in one direction overlapping each other, the flexibility of each ring plate is reduced. When superimposed, it acts as a kind of pseudo coil. Unlike a coil spring, it does not have uniform physical properties in any direction at 360 degrees, but when attached, strong elastic force is obtained in any of the following directions: bending to the side of the body, twisting and rotating the body, and bending or warping the back. Can be Furthermore, since it is plate-shaped in a horizontal cross section, the thickness can be reduced.

The effect of the body-side support elastic body 120 will be described as follows.
In the state of the prior art in which the body-side support elastic body 120 is not used, when taking a posture in which the body side is bent left and right and the upper body is bent left and right as a working posture, the worker himself unconsciously does not roll in the left and right direction as it is. It was necessary to support with the back muscles and step on the bent side. For this reason, a burden was placed on the back muscles and a burden on the legs and hips. However, if the body-side supporting elastic body 120 is provided, the body-side supporting elastic body 120 is bent and the elastic force is generated due to the movement of taking the posture of bending the body side in the left-right direction and bending the upper body left and right as a working posture, Naturally, the elastic force acts in a direction in which the worker himself does not roll to the side, and the burden on the back muscles and the burden on the legs and hips during work is reduced accordingly.

  Further, even when performing a return operation of returning the upper body after taking a posture in which the body side is bent left and right and bending the upper body left and right, the elastic force of the body side support elastic body 120 acts in the direction in which the body side is raised. The body-side supporting elastic body 120 assists the returning operation for raising the body.

  The same applies not only to the bending of the body side, but also to operations such as twisting and rotation, and the body-side supporting elastic body 120 bends in accordance with the operation to generate an elastic force. This elastic force assists the worker in returning from a posture such as a twist or rotation on the body side.

FIG. 4 and FIG. 5 are diagrams simply showing the situation.
FIG. 4A shows a state in which the worker bends the body sideways and performs an operation involving bending warpage on the body side. At this time, the body-side supporting elastic body 120 on the right body side is bent to the right side of the body and deformed. In addition, the body-side supporting elastic body 120 on the left body side is deformed to the right side of the body. In this state, as shown in FIG. 4B, the elastic force generated in the body-side supporting elastic body 120 acts in a direction to return the worker to the bent state.

  FIG. 5A shows a state in which the worker twists his body. Also at this time, the body-side supporting elastic bodies 120 on the left and right are deformed. In this state, as shown in FIG. 5B, the elastic force generated in the body-side supporting elastic body 120 acts in a direction for returning the twisted state of the worker.

Next, the waist support elastic body 130 will be described.
The waist support elastic body 130 is an elastic body, and generates an elastic force by bending. It is an elastic body arranged in the vertical direction on the back of the waist of the work clothing main body 110. In this configuration example, it is inserted and arranged in four waist elastic sheaths 113.
The upper part of the body-side support elastic body 120 is near the armpit of the work clothing main body 110, and the upper part of the waist support elastic body 130 is the back of the waist of the work clothing main body 110. This means that the upper part of the body-side support elastic body 120 extends to a position higher than the upper part.
The structure of the waist support elastic body 130 may be any as long as an elastic force is generated by bending, but like the body side support elastic body 120, the leaf spring shown in FIG. The coil spring shown, the pseudo coil spring shown in FIG.

FIG. 6 is a diagram simply showing a state in which the worker has performed a bending motion.
FIG. 6A is a view from a slightly oblique direction on the back side, and FIG. 6B is a view from a side direction. As shown in FIG. 6A, the four waist support elastic members 130 are bent forward and deformed. In this state, the elastic force generated in the waist support elastic body 130 acts in a direction to support the worker's waist upward.

The effect of the waist support elastic body 130 will be described as follows.
In the state of the prior art in which the waist support elastic body 130 is not used, when taking a posture to bend the waist as a working posture, the worker himself unconsciously supports with the back muscle around the base of the waist so that the worker does not roll forward. It was necessary to step on For this reason, a burden was placed on the back muscles and a burden on the legs and hips. However, if the waist support elastic body 130 is provided, the waist support elastic body 130 is bent and the elastic force is generated due to the movement of taking the posture of bending the waist as a working posture, and the worker himself naturally rolls forward. The elastic force acts in the direction that does not exist, and the burden on the back muscles and the burden on the legs and hips during work is reduced.
Further, when performing a return operation of raising the upper body after taking a posture in which the waist is bent, the elastic force of the waist support elastic body 130 acts in the direction in which the waist is extended. Assisted by elastic body 130.

  As described above, according to the work assisting suit 100 shown in the first embodiment, the body side supporting elastic body 120 allows the worker to simply wear the work assisting suit 100 of the present invention and perform bending, twisting, and turning on the body side. Operation can be supported. In addition, the waist and back muscles of the worker can be supported by the waist support elastic body 130.

A work assistance suit 100a according to the second embodiment will be described.
The work assistance suit 100a according to the second embodiment uses the work clothing shoulder blade portion 140.
FIG. 7 is a diagram schematically illustrating a configuration example of the work assistance suit 100a according to the second embodiment.
Also in this configuration example, the work assistance suit 100a is a so-called waistcoat-type example.
As shown in FIG. 7, the work assist suit 100 a according to the second embodiment includes a work clothes main body part 110, a body side support elastic body 120, a waist support elastic body 130, a work clothes shoulder blade part 140, and a lower part. A connecting device 150 and an elastic cord body 160 for supporting a back muscle are provided.

  The working clothing main body 110, the body-side support elastic body 120, and the waist support elastic body 130 may be the same as those shown in the first embodiment, and the description thereof is omitted here and is shown in the first embodiment. The configuration that does not exist will be described in detail.

The work clothing shoulder blade portion 140 is a portion of the work auxiliary suit 100 that covers at least a part of the worker's shoulder blade. Here, the vest type is taken as an example, so it has a shape corresponding to the upper shape of the vest-type working clothing main body portion 110, but as another pattern, a shape with a sleeve or a so-called tank top shoulder strap The shape of the part may be used.
The work clothing main body portion 110 and the work clothing shoulder blade portion 140 may be a separate type or an integral type. In this configuration example, the vest-type work clothing main body 110 is made of a different material from the cloth, but is sewn and integrated with the upper surface of the work clothing main body 110 near the shoulder blade. I have.

  The work clothing shoulder blade portion 140 includes the main body cloth portion 141 and the upper connecting member 142.

The main body cloth portion 141 is the main body of the work clothing scapula portion 140.
The material of the body cloth portion 141 is not particularly limited, but is preferably a material that is durable, has air permeability, and has a water-repellent surface.

  The upper connector 142 is a connector provided on a part of the back of the work clothing scapula near the scapula, and is a member for connecting and fixing the upper part of the elastic cord body 160 for back muscle support. The shape and system of the connecting tool are not particularly limited as long as the connecting member can connect and fix the elastic cord body 160 for back muscle support. For example, there are various types such as so-called eggplant, hanging can, flat can, D-can, side release type buckle, and front release type buckle. It may be a strap or a cord.

The lower connecting device 150 is a connecting device provided on a part of the back of the waist or the side of the waist of the pants worn by the worker, or on a portion of the back of the waist or the side of the waist of the main body of the working clothes. A member for connecting and fixing the lower part of the body 160. Here, it is a button attached to a piece of cloth sewn on a part of the pants. In this configuration example, it is provided at two places on each of the left and right sides.
The structure of the lower connector 150 as the connector is assumed to be of the same type as the upper connector 142, but the shape and method as the connector can connect and fix the elastic cord body 160 for back muscle support. It is not particularly limited as long as it is one. As with the upper connector 142, there are various types such as a so-called eggplant, a hanging can, a flat can, a D-can, a side release type buckle, and a front release type buckle. It may be a strap or a cord.

The elastic cord body 160 for back muscle support is an elastic body that is connected to the upper connector 141 and the lower connector 150 and attached between them. Since the upper connector 141 is located on a part of the back near the scapula and the lower connector 150 is on the back of the waist or the side of the waist, it is an elastic body that directly connects the shoulder and the waist at the back. In this configuration example, the elastic cord body 160 for supporting the back muscles is provided on each of the left and right sides, and the number is two.
In addition, although it is a material of the elastic cord body 160 for supporting the back muscle, the range covered by the elastic cord body 160 for supporting the back muscle extends from the top to the bottom of the back. Therefore, a smaller thickness is better. Here, a material such as a so-called rubber string is used.

FIG. 8 is a diagram schematically illustrating support by the elastic cord body 160 for supporting the back muscles in a state where the worker wearing the work assistance suit 100a according to the second embodiment performs a work that bends forward significantly.
FIG. 8 is a view from the side. As shown in FIG. 8, the elastic cord body 160 for supporting the back muscles extends along the back, so that the elasticity is greatly increased. In this state, the elastic force generated in the elastic cord body 160 for supporting the back muscles acts in a direction in which the scapula of the worker is pulled back toward the waist.
In addition, as described in the first embodiment, the elastic force for raising the chest also acts on the elastic body 120 for the body side support, and the elastic force for raising the hip also acts on the elastic body 130 for the lumbar support. , Each superimposed force works to support the movement of the body.

The effect of the elastic cord body 160 for supporting the back muscle is described as follows.
In the state of the prior art in which the elastic cord body 160 for supporting the back muscles is not used, when taking a posture in which the upper body is bent down and the shoulder is rounded as a working posture, the worker unconsciously supports with the back muscles so as not to roll forward. It was necessary to step on the foot. For this reason, a burden was placed on the back muscles and a burden on the legs and hips. However, if there is the elastic cord body 160 for supporting the back muscles, an elastic force is generated by the elastic cord body 160 for supporting the back muscles with the movement of taking a posture in which the upper body is tilted forward and the shoulder is rounded as a working posture, and The weight of the worker naturally works in the direction in which the worker himself does not roll forward through the connecting device 150, and the burden on the back muscles and the burden on the legs and hips during work is reduced.

  Further, when performing a return operation of raising the upper body after taking a posture with a large bent and rounded shoulder, the elastic force of the elastic cord body 160 for supporting the back muscles works in the direction of pulling back the shoulder and also in the direction of lifting the waist. The returning operation for raising the body is supported by the elastic cord body 160 for supporting the back muscles.
