Load carrying supporter
[Object of the Invention] To decrease the load applied to a spine so as to prevent and treat lumbago, when carrying various shapes of goods with hands. [Solution] A load carrying supporter used for carrying goods by hands, comprising an attachment attached to a worker's body and a load supporter fixed to the attachment. The attachment attached around the worker's waist, and the load supporter has a high frictional resistance material facing outward from the worker's body. Most of the load is lead to the waist and the distance between the loading point and the spine becomes small. Therefore the pressure and the bending moment on the spine become very small.
I claim the benefit of priority of Japanese patent application No.

This invention relates generally to a load carrying supporter used to assist carrying goods with hands.
BACKGROUND ARTAs shown in the
This load applied to the spine many times causes lumbago. Japanese suspension rate from work caused from lumbago is 24.5% reported in 2011. The economic loss of U.S.A. is 7,000,000,000 dollars per year reported in 2013.
Heretofore, there are various types of load carrying supporter which intends to decrease the load applied to hands, arms, shoulders and a spine listed as follows.

The prior arts disclosed by the above patent literatures, show a shelf supported by a waist belt. The load is applied to a waist through the shelf and the waist belt. By these arts, the bottom edge of the goods to be carried must be lifted up to the shelf situated at the waist position.
This means that the vertical travel of the goods from the ground to the waist position is high. And in case of the tall goods, it is unstable to carry the goods at too high position.
Also the structures of these prior arts are bulky and project outside from the body of workers, and disturb the movements of them.
Solution to ProblemA load carrying supporter used for carrying goods by hands comprising; an attachment attached to a worker's body; and
a load supporter fixed to the attachment,
wherein the attachment attached around the worker's waist, and the load supporter has a frictional resistance material facing outward from the worker's body.
Above load carrying supporter, wherein the frictional resistance material has a higher frictional resistance coefficient than 0.6.
Above load carrying supporter, wherein the frictional resistance material favorably has a higher frictional resistance coefficient than 1.0.
Above load carrying supporter, wherein the frictional resistance material most favorably has a higher frictional resistance coefficient than 1.6.
Above load carrying supporter, wherein the frictional resistance material is selected from the group of soft plastics such as vinyl chloride, polyester, elastomer, synthetic rubber, silicone rubber, urethane rubber or natural rubber.
Above load carrying supporter, wherein an anti-slip process is added to the frictional resistance material.
Above load carrying supporter, wherein the anti-slip process includes micro foam.
Above load carrying supporter, wherein the load carrying supporter is applied to a waist belt.
Above load carrying supporter, wherein the load carrying supporter is applied to a waist porch.
Above load carrying supporter, wherein the load carrying supporter is applied to a corset.
Above load carrying supporter, wherein the load carrying supporter is applied to an apron.
Above load carrying supporter, wherein the load carrying supporter is applied to clothes.
Advantageous Effects of InventionBased on above mentioned invention, it becomes possible to decrease the load applied to the hands, arms, shoulders and the spine, when carrying various shapes of goods.

The attachment 20 has a belt 21 made of a flexible material such as fiber, rubber or soft plastics, and a first connector 22 and a second connector 23 fixed at the both end thereof. The belt 21 is attached surrounding the waist 81. The first connector 22 and the second connector 23 have loop and hook fastener so that the adjusting is easy.
The load supporter 30 has a base 31, the frictional resistance material 32 and a support connector 33 fixed on the base 31. The frictional resistance material 32 is a sheet or cloth made from the group of soft plastics such as vinyl chloride, polyester, elastomer, synthetic rubber, silicone rubber, urethane rubber or natural rubber.
An anti-slip process may be made on the frictional resistance material 32.
The anti-slip process is micro bubble or unevenness made by a mechanical or heat foaming. For example, 10 micro or 20 micro capsules are mixed into the frictional material 32 and heated at 120 degree centigrade.
The other method of anti-slip process is small suckers made on the surface of the frictional resistance material 32. High frictional resistance paint may be coated.
The frictional resistance material 32 is situated parallel to the surface of the waist, facing outwardly.
The support connector 33 may be opened downwardly as shown by

More over the load carrying supporter 10 can bear not only the vertical forces but also the horizontal forces because of the high frictional resistance effect. This means that the load carrying supporter 10 can prevent the horizontal slip of the goods.
The load carrying supporter 10 does not project outwardly like the prior art. As shown by

-
- 1 A material to be tested is set on a table facing upward.
- 2 A piece of corrugated cardboard is set on the test material.
- 3 Weight of 400 g is set on the corrugated cardboard.
- 4 Pull the cardboard and measure the force F g when the cardboard starts to slip.
- 5 The frictional resistance coefficient is F divided by 400.
The corrugated cardboard is chosen, because many goods are contained in the corrugated cardboard box.
Referring to Table 1, the measuring test results are shown.
When the frictional resistance coefficient is over 0.6 and 1 or under 1, the small effect can be obtained.
When the frictional resistance coefficient is over 1 and 1.6 or under 1.6, the sufficient effect can be obtained.
When the frictional resistance coefficient is over 1.6, the most sufficient effect can be obtained.
