Description

Method for adjusting sole weight

The main object of the present invention is to provide a method for adjusting the weight of a sole, which utilizes a combination of a midsole of a hollow bag structure and a granular filler having flow characteristics, and utilizes the excellent fluidity of the granular filler to ensure Increasing the weight of the sole does not make the sole stiff, resulting in poor deflection and shock absorption, which is not conducive to the movement and movement during wearing.

In the past, weight training used sandbags or lead blocks to increase the weight of the foot to train the leg muscles. However, when the weight of the load is placed above the soles of the feet, it will cause extra or even excessive burden on the joints, which will cause impact on the knees. hurt.

If the sole weight is increased by filling the sole material with iron shoes, iron sand or steel balls, the sole will be stiff, the degree of deflection and the shock absorption will be deteriorated, which is not conducive to the travel and movement during wearing.

The inventor of this case has devoted himself to the research and development of air cushion for more than 30 years. It has been found that the air cushion is a hollow bag body. In addition to increasing the elasticity by driving in the air, filling other fluid substances can also achieve the shock absorption effect like air, and tried to fill in the iron beads. Iron sand or steel balls, etc., commissioned by the Taiwan Footwear Technology Center, found that the effect of iron sand is the most unsatisfactory, but found that the steel ball is the most excellent in fluidity, and its shock absorption function is the most ideal (see Annex I). When the inventor of the present invention actually wears the weight training shoes filled with steel balls, it is obvious that the flexing and flexibility are the same as those of the sports shoes which are generally highly flexible and shock absorbing. Protecting the body and foot tissue, and wearing it in everyday life, creating a new concept of integrating training into life.

The invention relates to a method for adjusting the weight of a sole, which mainly comprises a shoe with a hollow bag structure a combination of a bottom and a granular filler having a flow characteristic, the midsole having a hollow bag structure comprising a top and a bottom surface defining a bag structure, the granular filler being a material having a weight The composite structure is a granular filler body having a flow characteristic, and the granular individual has any geometric shape which reduces the friction between each other, and the ideal structure is a microsphere with a smooth surface, and the material thereof It can be made of metal, non-metal, plastic, rubber, ceramic, glass, etc.

The granular body is filled in the hollow bag structure, and a connecting pipe communicating with the outside can be preset at any position of the hollow bag structure, and the granular body can be further filled into the bag through the connecting pipe, the connection The outer end of the tube may further be provided with a mechanism for blocking, so that the filled granular body is not leaked, and the outer end of the connecting tube may be selected to be sealed. Alternatively, the opening of the hollow bag body structure may be preset to communicate with the outside, through which the granular body may be filled in the bag body, and then blocked by sticking or hot melt glue after completion. The opening is sealed.

The hollow bag body structure further includes a predetermined recess for defining a bag support structure characteristic, the recess being defined by a support surface formed by extending the upper or lower surface, the support surface being independent of the hollow bag body Within or at least a portion of the support surface is coupled to the side surface of the hollow bag body.

The upper or lower surface of the hollow bag structure may be a planar or curved geometry, and the side surface may be a separate continuous surface, and the upper edge is connected to the upper surface, and the lower edge is connected to the lower surface. The other similar structure of the side surface is formed by extending the upper or lower surface of the hollow bag body in opposite directions and connecting at a predetermined position.

The hollow bag body structure may be an open bag body that is sealed or communicated with the outside, and may further include a connecting pipe that communicates with the outside, and the connecting pipe may further be provided with a valve that can inflate and maintain the pressure of the sealed bag body. Or any structural element that can inflate the sealed bag body, the sole of the present invention is given Better shock and stability.
