Here, the waist 81 refers to the pelvis and its upper vicinity.

  The body mounting portion 20 is composed of a band 21 made of a flexible material such as fiber, rubber, or plastic, and a first coupler 22 and a second coupler 23 provided at both ends of the band 21. . The belt 21 goes around the waist 81 and is attached to the body. The first coupler 22 and the second coupler 23 are easy to attach and detach and adjust because the hook and loop fasteners are used.

  The luggage support 30 is configured by a friction material 32 being coupled to the surface of a base 31 and a support connector 33 being coupled to the base 31. The friction material 32 is formed of a high friction material such as natural rubber, synthetic rubber, silicone rubber, urethane rubber, elastomer, soft synthetic resin such as vinyl chloride or polyester in the form of a sheet or woven cloth, and is subjected to anti-slip processing. It is.

  Anti-slip processing includes micron-sized bubbles or surface irregularities caused by mechanical foaming or thermal foaming. For example, thermal foaming includes a method in which a foaming agent is enclosed in 10 to 20 μ microcapsules, mixed in a base material, and heated to 120 ° C. The friction material 32 is attached so as to be substantially parallel to the outer surface of the waist and to be disposed outwardly on the outer surface of the luggage support portion 30.

  As another method of anti-slip processing, a method may be adopted in which a minute recess is provided to cause a suction cup action or a minute protrusion is provided to improve the application. Further, the surface of the fiber may be inclined and raised to increase the frictional resistance in one direction, or a high friction paint may be applied. Since these depend on the material on the load side, they may be selected according to the load or combined.

By doing in this way, the load by a luggage | load can be supported by a waist | hip | lumbar part.

  FIG. 10 shows another example of use. In the case of a tall baggage such as a refrigerator as in A, it is easier to carry the baggage by carrying it on the back than on the front. The present invention is particularly useful when there is no handle such as a refrigerator or large furniture. You can also hold your baby like B. The present invention is useful when holding and lowering repeatedly because it does not take time for desorption like a hug.

  Like C, the package can be supported with one hand, so that the courier delivery person can support the package with one hand and deliver the slip with the other hand. It is also useful for people who have difficulty with one hand. In addition, there is a method of supporting the load on the side.

FIG. 11 shows a method of measuring the friction coefficient of the friction material. Place the friction material upward on the table, and place cardboard and 400g weight on it. Pull the cardboard through the spring only, and let Fg be the starting force. The cardboard was used because many packages are stored in cardboard containers.
The friction coefficient μ is μ = F / 400.

Table 1 shows the evaluation results of the friction coefficient and the effect of the invention. It has been found that if the friction coefficient is less than 0.6, there is no effect. Therefore, it was found that the friction coefficient must be 0.6 or more at the minimum, and 1 or more is desirable.
