Description

  The present invention suppresses the rise or fall of body temperature in order to reduce the physical temperature such as the rise in body temperature and back pain that occurs from the same posture as the environment temperature of bathing assistants in workers and nursing care facilities under high temperature environments The present invention relates to lightweight and compact work clothes for assisting workers (including assistance clothes) that are integrally provided with a back pain prevention belt portion that prevents back pain that occurs in the same posture as the air conditioning function.

When working in a high temperature environment, for example, when working in a fruit plantation, the largest amount of work for harvesting in the fall is the hot weather from June to August, so work comfortably due to the intense heat There is a need for a heat protection device that can be used.
In addition, with the increase in the population of older people, nursing care facilities have increased recently, and physical burdens on bathing caregivers and the like have increased, and air-conditioning clothing for lowering body temperature is eagerly desired. In particular, the number of users of welfare facilities and nursing care facilities has been increasing in recent years. Among them, bathing assistants have been screaming for dehydration due to the heat of the work environment, which has been cited as an important issue. Yes.
Also, outdoor work in extremely cold areas is heavy with cold protection clothing, and the difficulty of work has been screamed, and light and comfortable heating clothing is required.
When it is necessary to cool the body temperature of a person, for example, when continuously cooling the head (forehead, temples, etc.), neck, arms, etc., water pillows, ice pillows, ice bags, ice non (trade name), etc. Cold insulation material is used.

Hereinafter, the prior art will be described.
Japanese Patent Publication No. 2002-125994 describes a belt-shaped heat shield using a cold pack.
A belt-shaped heat protection device according to the prior art includes a wearing tool having a bag portion at a substantially central portion in the longitudinal direction of a non-woven fabric or woven fabric processed into a belt shape, and a cold pack that is detachably stored in the bag portion. FIG. 4 shows an example of a conventional belt-shaped heat shield (see Patent Document 1).
This heat protection device 1 is composed of a mounting tool 2 that is formed by processing a nonwoven fabric into a belt shape, and having one of the substantially central portions opened to be processed into a belt shape, and a cold pack 3 that is stored in the mounting tool.

Japanese Patent Laid-Open No. 10-259513 describes a cooling garment that absorbs condensed water generated around the coolant and can easily discharge the absorbed condensed water to the outside. (See FIGS. 5-6).

FIGS. 5 to 6 show a state of wearing a cooling garment, which is a conventional technique (see Patent Document 2). Conventional cooling clothing includes a coolant that cools the human body, a heat-insulating material that wraps the coolant in a separable manner and that has at least a surface that contacts the coolant, and stores the heat-insulating material in a freely accessible manner. It is described that the storage member is a clothing main body on which the storage member is detachably mounted.
The symbols used in FIGS. 5 to 6 are as follows.
DESCRIPTION OF SYMBOLS 1 ... Cooling clothes 2 ... Maintenance worker 3 ... Work clothes 5 ... Storage bag (storage member)
This is because a heat insulating material having water absorption is stored at least on the surface in contact with the coolant so that it can freely enter and exit the storage member, so that the heat insulating material that has absorbed condensed water is taken out of the storage member and the condensed water is removed. It can be easily removed outside.

JP 2002-125994 A Japanese Patent Laid-Open No. 10-259513

  However, the conventional belt-shaped heat shield using the above-described cold pack (corresponding to the work clothes of the present invention) and the cooling clothes (corresponding to the work clothes of the present invention) are the same under a high temperature environment. Prevention for back pain that occurs during work is not considered and not even mentioned.

In particular, in the cooling garment disclosed in Japanese Patent Application Laid-Open No. 10-259513, a cold insulating gel material having a melting point temperature of 0 ° C. or lower is used (Patent Document) 1 [0025] “The surface of the coolant 6 The temperature is around 0 ° C., which is the melting point temperature of the latent heat storage material 20, but since the heat insulating sheet 8 is interposed between the human body side, overcooling of the human body can be prevented. ” However, it is configured to be wrapped with a heat insulating material to prevent overcooling.
For this reason, it is clear that the cooling effect is significantly impaired by using work clothes and heat insulating materials that are not considered to be breathable up to the human body, and the amount of heat generated from the human body makes it between the coolant and the human body. There is concern that thermal stagnation may occur and the opposite may be felt hot. In addition, the cooling material is a general cold gel material, and since the melting temperature is 0 ° C. or less after freezing, it is necessary to freeze it in a freezer in advance, and the preparation is complicated and the human body is hot. If the temperature is higher than or equal to 30 ° C., the temperature difference between the freezing temperature and the environmental temperature is 30 ° C. or more, and a large amount of condensed water is generated.

Further, in the case of such work clothes, the cold energy of the cold insulation gel material is used for the generation of condensed water, the amount of cold energy used for the original human body cooling is reduced, and the cooling efficiency is lowered.
In order to exert the cooling effect of the clothing for cooling, a cold insulation gel material of a considerable weight or more is required, so that the weight of the work clothing itself is increased and the physical burden is reduced.
The present invention pays attention to such a conventional problem, and bathing assistance assistant clothes and bathing assistance workers in a high temperature environment that greatly reduce the physical burden caused by low temperature pain and bathing assistance workers performed in welfare facilities for the elderly. The present invention provides work clothes that can be reduced in weight for workers.
More specifically, the problems to be solved by the invention are as follows.
The first problem of the present invention is to suppress the heat release from the human body accompanying the increase in body temperature, to suppress the increase in the body temperature of the worker, to give a cooling feeling, and to provide comfort to the worker in a high temperature environment It is to provide work clothes that can be worn.
The second problem of the present invention is to provide work clothes with good energy efficiency by improving the cooling efficiency without generating condensed water.
The third object of the present invention is to provide a work clothes that can realize weight reduction by improving cooling efficiency without generating condensed water.

  Means for solving the problems of the present invention are the inventions described in the claims.

The present invention integrally comprises a lower back fixing means for preventing low back pain associated with work, and a low back pain prevention band portion made of a breathable and stretchable mesh material that integrally forms a low back pain prevention band, The upper part of the mesh material, which is made of the same material as the back pain prevention band part and is in close contact with local areas such as the back, neck, and armpits of the upper body, and has good breathability and elasticity They are spaced plurality gap side in contact with the human body wearing portion is accommodated a contact side of the body and the housing pocket formed by the mesh material of good non-stretchable breathable, the housing pocket A plurality of hermetically sealed first sheet-like packages, a second sheet-like package accommodated in the first sheet-like package, and a cold storage heat material filled in the second sheet-like package (in a desired amount) And the second sheet-like package In addition to the second sheet-like package, the second sheet-like package housed in the first sheet-like package and a heat insulating sheet having substantially the same area are provided on the non-contact side with the human body. It is the clothes for work (for bathing assistance etc.) characterized by.
Furthermore, the cold storage heat material is a work clothes characterized by having a melting or solidification temperature of 20 ° C. or higher.
The heat storage material has a melting or solidification temperature of 20 ° C or higher, so that the generation of condensed water on the surface of the cold insulation material is remarkably reduced, and the cold insulation energy possessed by the cold insulation material is used to generate condensed water. However, since it is used only for cooling the original human body, a remarkable effect unpredictable by a person skilled in the art that the amount of cooling energy is reduced and the cooling efficiency is improved is exhibited.
By improving the cooling efficiency, the cooling effect of the cooling garment will be exerted. If the cooling efficiency of the conventional technology is acceptable, a considerable amount of cold insulation material will be saved. The weight was reduced, and the physical burden on the operator could be reduced.

The first sheet-like package is characterized in that the presence or absence of storage in the storage pocket is selectable and detachable.

In addition, it is an assistance clothing worn by an assistant during bathing assistance in an elderly care facility, etc., and the storage pocket of the cold storage material is not provided in the chest and abdomen that are the front of the wearer itself It is the clothes for assistance.

  Further, the heat insulating material disposed on the non-contact side of the human body is a work clothes characterized by being a resin sheet having discontinuous bubbles.

As described above, the present invention is a work clothes for bathing assistants and the like performed in a nursing facility and the like, and is composed of a highly breathable mesh fabric. Therefore, heat dissipation from the human body accompanying an increase in body temperature is achieved. Without hindering, an increase in the body temperature of the worker can be suppressed and a cooling feeling can be given, and comfort can be given to the worker in a high temperature environment.
At the same time, since the jacket and the back pain prevention unit are integrated, it is optimal as a support clothing for a bathing assistance worker who often repeats the same work and shouts back pain.

  The first embodiment, which is the best mode for carrying out the present invention, will be described below with reference to the drawings.

[Example 1]
A first embodiment of the present invention is shown in FIGS. FIG. 1: has shown the schematic diagram seen from the back side of the state which wore the assistance clothes which are this invention. Moreover, FIG. 2 has shown the schematic diagram seen from the front side in the state which wore the same assistance clothes. 101 is a back pain prevention zone. The back pain prevention band 101 is integrally provided with a resin fixing plate 102 as a waist fixing means so as to be in close contact with the lumbar portion. Further, as shown in FIG. 2, the back pain prevention band 101 is locked and fixed on the front surface of the waist of the wearer who is an operator. For example, the work clothes in FIG. 2 employ a method of bonding and fixing a cloth generally referred to as Velcro (registered trademark). Reference numeral 103 denotes a rubber band for reinforcement, which is a waist fixing means for preventing back pain. The rubber band 103 is fixed at the center of the back surface, and has a function of applying an urging force for fixing the lumbar part according to back pain. Moreover, the material which forms the lower body part which is a back pain prevention belt | band | zone part is formed as a clothes by the mesh cloth etc. with a high elasticity and air permeability.

  Reference numeral 104 denotes an outer garment made of the same fabric as the back pain prevention belt portion, which is a highly stretchable and breathable mesh fabric and is integrally formed with the back pain prevention belt portion 101. These necks are formed so as to cover the human body 107 closely.

  Here, since the whole fabric uses a mesh fabric having high stretchability and air permeability, the fabric generally tends to adhere to the surface of the human body to be worn.

  A storage pocket portion 105 is a storage means for the first sheet-like package 106. FIG. 3 shows a cross section of the storage pocket portion 105 that stores the first sheet-like package 106. A indicates the surface of the human body to be worn. The storage pocket portion 105 is a non-stretchable and highly breathable mesh fabric that is added to the inner surface of the mesh fabric that is the outer jacket portion 104 that is the human body 107 side, and has a volume of the first sheet-like package 106. It has a slightly larger internal volume. In order to make the first sheet-like package 106 detachable, for example, only the upper part is opened so that the stored first sheet-like package 106 does not fall off during work in the work posture of an assistant or worker. It has become a thing.

  The first sheet-like package 106 is, for example, a nylon bag-like package and is hermetically sealed. In the first sheet-like package 106, a second sheet-like package 108 is disposed on the contact side with the human body 107, and a heat insulating sheet 109 is inserted on the non-contact side with the human body 107. The heat insulating sheet 109 is a urethane-based sheet having discontinuous bubbles and being light in weight.

  In particular, the storage pocket portion 105 is a highly breathable mesh fabric but is non-stretchable. Therefore, when the first sheet-like package 106 is inserted, the storage pocket portion 105 can be prevented from sagging due to the weight of the package and is attached. No discomfort to workers.

  Here, the major difference from the prior art is that in the present invention, the clothes are worn on the inner side of the work clothes or other clothes or on the bare skin so that they can be worn almost closely to the human body.

  In general, taking a bathing assistance work in a nursing facility as an example, a work apron called a bathing assistance apron is often worn from the viewpoint of hygiene for bathers. Therefore, it is considered that the work clothes of the present invention can be worn inside a bathing assistance apron or the like.

  In particular, in the description of the present embodiment, the case of wearing on the bare skin is shown, but the same result can be obtained even if it is worn from underwear or a general T-shirt.

In addition, as the heat storage cold material 110 enclosed in the second sheet-like package 106 of the present invention, a material whose phase transition temperature, that is, melting and solidification temperature is close to room temperature is selected. There is no need to put it in the refrigerator in advance to make it extremely cold.
For example, the heat storage cold material may be an organic alkylene glycol aqueous solution.
Conventionally, inorganic salt compound-based heat storage and cooling materials have also been proposed. However, in the case of salt-based heat storage and cooling materials, since the phase change of the crystal, that is, the solidification and melting phenomenon, is utilized in the solidified state, the shape and size of the crystal tend to be uneven. In a solidified state, the adhesion to the human body may be poor.
In the present invention, an organic heat storage / cooling material is employed in consideration of the above-described problems.

In addition, since the solidification temperature is 0 ° C. or lower in the case of a conventional cold-retaining gel, it is necessary to keep the temperature extremely low before it is solidified in a freezer or the like before it is solidified.

In the present invention, since the temperature at which the regenerator material solidifies is about 10 ° C. lower than the body temperature, it can be mounted without a sense of incongruity from a low temperature such as being too cool at the time of mounting, that is, before the work when the body temperature has not increased. However, there are major features.
Here, a mechanism for giving a cooling feeling will be described.
The heat storage and cooling material in the present invention utilizes the latent heat of action of a substance. Here, the meaning of the term “latent heat” is known to include three states, solid, liquid, and gas, and a large heat transfer occurs between these states when the state changes. . This large heat transfer is called a latent heat action.

For example, in the case of water, the specific heat of water is 4.2 J / g, but when changing (melting) from ice to water, it is 335 J / g, which is 80 times from the outside of the ice. It is known that a very large amount of heat energy is required, that is, endothermic.
The heat storage and cooling material of the present invention uses the latent heat action at room temperature to give a relatively low temperature to the human body to obtain a cooling feeling. Specifically, the phase change (change from solid to liquid) temperature at which transition to solidification or melting having a large endothermic effect is made to be 20 ° C. or more by using an organic material so that it can be more closely adhered to the human body.

  In addition, when the temperature is kept below freezing as in the case of a conventional cold-retaining gel material, there is a concern that the temperature difference from the surroundings is relatively large, and condensation is likely to occur due to the human body and ambient temperature. Is relatively small and has the advantage of less condensation.

  Moreover, compared with the conventional cold-retaining gel material, there is an advantage that it is not necessary to be solidified in a freezer, and that it can be used simply by being left at a solidification temperature or less, which is very convenient.

  In the first sheet-like package 106, the heat-insulating sheet 109 is arranged on the surface side that does not come into contact with the human body so as to have substantially the same surface area as the second sheet-like package 108. Heat escape from the side and inflow of heat from outside the periphery can be greatly suppressed, and heat absorption, that is, a cooling effect can be expected over a long period of time.

  If it is strong, since the cooling effect can be expected without increasing the weight of the regenerator material, a lightweight second sheet-like package 108 can be realized, and overall lightweight work clothes can be achieved.

  Further, in the work clothes of the present invention, the first sheet-like package 106 is made detachable, so that the user can selectively decide depending on the necessity of wearing, and the weight can be reduced by reducing the package. It can also be done.

  In particular, bathing assistance work at nursing care facilities, etc. has many assistance work for holding elderly people such as elderly people at the chest, so it is also important not to give the person a feeling of cooling at that time, The present invention is characterized in that the storage pocket portion 105 of the regenerative cold material 110 that is the first sheet-like package 106 is not provided in the chest and abdomen that are the front of the wearer.

  In particular, there is an advantage that an assistance apron or the like necessary from the hygiene aspect generally worn by bathing assistance workers can be mounted on the work clothes of the present invention.

In the above description, it is not necessary to pre-cool in the refrigerator or the like before wearing the work clothes of the present invention, but there is no problem even if the refrigerator is kept cool.
In addition, the work clothes according to the present invention are also characterized in that a back pain prevention function is integrally formed.

  In a high temperature environment, workers often scream back pain or the like at the same time depending on the work posture in addition to the thermal physical load. Specifically, in bathing assistance work in a care facility, there are about 40 bathers (caregivers) at one time, and the same posture is increased by repeating the same work, especially low back pain is a problem. It has become.

  Actually, there is a fact that the lower body part becomes heavy work clothes by using a thick corset by using a corset for preventing back pain, and the work clothes are heavy and difficult to operate.

  In the present invention, in addition to the cooling function for suppressing the above-described increase in body temperature, the back pain prevention function unit is formed integrally with the work clothes.

  This is made of a stretchy and highly breathable mesh material that is easy to adhere to the body, so there is little discomfort when wearing it, and the back pain prevention part is also thin and lightweight work clothes, so work can be done There is an advantage that it is easy to remarkably reduce the physical burden. In particular, it is most suitable for support work clothes for bathing assistants performed in a care facility among workers in a high temperature environment.

  Further, in the present invention, in the present invention, in addition to the cooling function for suppressing the above-described increase in body temperature, the back pain prevention function unit has been described as a work clothes formed integrally with the work clothes. For a worker who does not need to be removed, the back pain prevention part can be deleted without any problem, and an increase in body temperature from the work environment can be suppressed.
