Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a movement assisting tool used for reducing the work load on a carrier when moving or carrying heavy objects.

[0002]

2. Description of the Related Art Conventionally, when a heavy article such as furniture is manually moved, a blanket or a slippery plate is placed under the heavy article.
In addition, when changing the posture of a bedridden person or moving, the fact is that the caregiver moves the bath towel and sheets laid under the body with two people, which is a heavy burden on the caregiver. there were.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is possible to work with a smaller force when moving or transporting a heavy object that can be handled manually, and It is intended to provide an assisting tool in which the components are not unevenly distributed. Further, the present invention aims to provide an auxiliary tool that prevents discomfort caused by static electricity during movement and transportation.

[0004]

The present invention achieves the above object, and is a hollow cylindrical structure in which a fiber cushion material including a fiber cushion joined with a binder fiber is wrapped with a side material, The gist of the movement assisting tool is that the woven fabric has a dynamic friction coefficient of 0.3 or less.

The present invention will be described in detail below. The auxiliary tool of the present invention is used for moving articles and as a care tool. For example, when used as a care tool, a patient is placed on a hollow cylindrical structure, and when the patient's body is pulled or pushed in the circumferential direction of the cylinder in a folded state, the cloth inside the structure Since the body is slippery, the structure itself rotates like a caterpillar with the patient's body resting on it, and the body easily moves in the direction in which force is applied, so position changes and movement to a wheelchair or stretcher are possible. Can be done easily. When using it as a care tool, the size of the movement assisting tool is approximately 30 cm to 1 m in width in the circumferential direction of the cylinder and 30 cm to 2 m in length in a state in which the patient is placed on top and is folded in half. Is.

FIG. 1 is a partial cross-sectional view showing a usage state of the movement assisting tool 1 of the present invention. In FIG.
The inner side material 2 is a woven fabric having a small dynamic friction coefficient, the outer side material 3 is preferably made of a fabric that is less slippery than the inner side material 2, and the fiber cushion material 4 wrapped by the side material is a binder fiber and is a main fiber. It is a fiber cushion material including a fiber cushion to which is joined. When the movement assisting tool 1 is used as a care tool, for example, the patient 5 is placed in a folded state as shown in FIG. When pushed by force, the inner lateral sides 2 have a small coefficient of dynamic friction and can be easily moved.

The fiber cushion material used in the movement assisting tool of the present invention needs to include at least a fiber cushion joined with binder fibers. By using the fiber cushion in which the fibers are joined together with the binder fiber, it becomes difficult for the fibers to move in the side material, and the shape change due to the movement of the fibers does not occur even when the present auxiliary tool is washed. Further, even when a heavy object is placed, it does not easily become a pechanco, and since the unevenness of the floor is absorbed, it is possible to move the object with a small impact.

The thickness of the fiber cushion joined with the binder fiber is preferably in the range of 5 to 50 mm and the compressive stress is in the range of 1 to 50 kg. If the thickness is less than 5 mm or the compressive stress is less than 1 kg, shock absorption may be insufficient. In addition, the thickness exceeds 50 mm and the compressive stress is 5
If it exceeds 0 kg, the auxiliary tool may not rotate smoothly when moving the placed object. Further, it is suitable that the basis weight is about 150 to 700 g / m ² . In order to keep the compressive stress of the fiber cushion material joined with the binder fiber within the specified range, the material of the main fiber and the binder fiber, the thickness, the cushion material density (determined by the basis weight and the thickness), the proportion of the binder fiber used, The heat fusion treatment temperature may be appropriately selected. The thicker the fiber, the higher the cushion material density, the higher the proportion of binder fiber used,
Further, the higher the heat fusion treatment temperature, the higher the compressive stress can be made.

Fiber cushions joined with binder fibers are mainly composed of synthetic fibers such as nylon, polyester and polypropylene, semi-synthetic fibers such as rayon, natural fibers such as wool and cotton, and nylon, polyester and polyolefin fibers. Can be produced by heat-treating a fiber laminate (web) in which binder fibers having the low melting point polymer as a binder component are mixed to melt and bond the binder component. As the main fiber and the binder fiber, polyester fiber is more preferable because it is easy to dry after washing, is economical, and has hardness as a cushioning material. If necessary, kneading or post-treatment of synthetic fibers may be used for antibacterial / deodorant, tick-proof,
It may be provided with functionality such as sweat absorption, far-infrared radiation, deodorization, and aroma.

In the present invention, as the fiber cushion material, only the above-mentioned fiber cushion bonded with the binder fiber may be used, or the cushion bonded with the binder fiber may be finished into a solid and elastic material. A bulky and soft fibrous web may be laminated on one or both sides to provide a softer and more resilient overall hit. As such a bulky and soft fiber web, a card web itself made of fine denier synthetic fiber cotton or synthetic fiber cotton surface-treated with a slippery silicone oil is sprayed or lightly sprayed with an adhesive resin solution. Examples thereof include those in which fibers are adhered to each other, or those in which a small amount of binder fibers are joined.

It is necessary to use a cloth having a friction coefficient of 0.3 or less as the side material which is the inside of the hollow cylindrical structure. If the coefficient of friction exceeds 0.3, it is unsuitable because the assisting tool of the present invention does not rotate smoothly when a heavy object is placed and moved. In order to reduce the friction coefficient of the cloth, the surface of the synthetic fiber filament woven fabric such as nylon or polyester may be resin-processed with a silicone resin, a thermoplastic Teflon resin, or the like.

As the side material which is inside or outside the hollow cylindrical structure, the warp is made of conductive fiber having an electric resistance value of 10 ¹⁰ ohm / cm or less, preferably 10 ⁷ ohm / cm.
It is suitable that the conductive fiber having the following electrical resistance value is a woven fabric used at intervals of 5 cm or less. 10 ¹⁰ ohm /
The conductive fiber having an electric resistance value of not more than cm can be obtained by kneading metal powder or conductive carbon into a yarn. A woven fabric that does not use conductive fibers may experience an unpleasant electric shock during use, especially when the atmosphere is dry.

The cloth used for the side of the hollow cylindrical structure on the front side is not particularly limited. However, when the assisting tool of the present invention is used as a care tool, it is the side that touches the body, and therefore, it is a cotton cloth. It is desirable to use a soft material, which is subjected to water repellency treatment as necessary, and which has a larger dynamic friction coefficient than the inner side material.

By quilting after putting the fiber cushion in the side fabric, the movement of the fiber in the side fabric of the fiber cushion material is further suppressed, and a high quality design is obtained, which is more preferable.

[0015]

When a heavy object is placed on the movement assisting tool of the present invention in a lying state and a force is applied to the heavy object in the horizontal direction, the fabric inside the structure is made slippery, and thus the structure itself. Can rotate like a caterpillar while holding a heavy object, and easily move the heavy object in the direction in which a force is applied.
