Abstract
The present invention is to provide a sole for rocking, which further improves the fit feeling, protects the foot of the wearer, and makes it stick to the rock, the hold and the pocket. A first stiffener disposed on the front sole in the form of a horseshoe along the toe and a second stiffener placed on the hind feet in the shape of a horseshoe along the heel; And a grip member placed on the front sole next to the stiffener.
Description
BACKGROUND OF THE
Climbing shoe is a specific type of shoe designed to climb rocks. It is a shoe that is worn to enhance the stability and climbing ability of the foot during rock climbing. As the climbing technique is developed and the climbing form is subdivided, A number of products have been released to demonstrate the special functions of.
Modern rock paintings use multi-piece patterns made from elaborate handicrafts to fit comfortably on the wearer's feet. The upper material is often leather, and other materials such as fibers and artificial leather are also used. The climbing rubber used in the sole is specially developed for rock climbing and uses T.D.R. (Thermo Dynamic Rubber), a petroleum chemical that is not a regular rubber.
The rocking down to the pointed toe box increases the holding power in the small hold and pocket, improving the toe hook performance. Provides more stable hooking and heel hook performance by providing molded cupsol on the heel, and provides a special buffer material on the heel outsole to absorb impact when dropped. And the bottom of the outsole is configured to provide strong grounding force with the rock.
To sum up, the abovementioned rocks include a foot-clad upper and an outsole to provide good grip, and an outsole to provide support for small holders and pockets, and a strong grip on the rock A heel portion including a mold cupsole for enhancing the hill-hook performance, and a cushioning material for absorbing the shock at the time of dropping.
The rocking with the above functions is now included in the rock paintings marketed in Las Portiva, Nexon Sports. These rocks are used in natural rock bouldering and climbing, indoor and outdoor sports climbing centers.
And the development direction of the current rock painting is to improve the fit to feel like bare feet, to protect the wearer's foot, and to stick to the rock, hold and pocket.
In this direction, the "load-dispersing shoe outsole" of Patent No. 10-1040648 (registered on June 03, 2011) discloses a plurality of unit protrusions protruding from the lower surface of the base plate and contacting the ground surface The unit protrusions are divided into upper and lower grooves so as to divide the unit protrusions into a predetermined number. The lower protrusions are formed so as to surround the grooves and contact the ground, and the grooves have heights lower than the height of the unit protrusions And a connection part formed between the bottom plate and the lower projection to disperse a load applied to the shoe and absorb shock generated in the ground, thereby providing a comfortable fit.
In the summary of the patent application No. 10-0668078 entitled " Functioning outdoor and enhanced durability, "in order to enhance the gripping force, Or less of a steel wire or a steel sheet made of a carbon tool steel composed of a main component of 0.5% or less of Mn, 0.3% or less of P, 0.25% or less of Cu, 0.25% or less of Ni and 0.3% or less of Cr, The durability of the shoe without changing the outer shape of the shoe and the function of dispersing the load on the toe of the front part of the shoe at the front of the shoe to the entire toe is improved so that the shape of the steel wire or the steel sheet It is possible to freely change the size and shape of a specific region, so that it is suitable for hiking, rocking, running, soccer, and soccer by meeting gait characteristics and specific foot type conditions ".
Finally, in order to protect the feet, the Utility Model Registration No. 20-0171623 (registered on Dec. 07, 1999, "Shoe Outsole Guide" is a guide to shoes, To provide an outsole guide having a curved bottom layer and a support between the outsole and the bottom of the shoe for protecting the ankle when the shoes are twisted together.
Therefore, the object of the present invention is to further improve the presently-marketed rocking structure, and in particular, to improve the comfort of the wearer ' s foot, to stick to the rock, the hold and the pocket, And to provide a sole for the purpose of reinforcing the grip force.
It is another object of the present invention to provide an integral band that grips the foot and provides foot attachment to protect the wearer ' s feet.
A stiffener placed on the front sole in the form of a horseshoe along the toes between the outsole and the insole, a second stiffener placed on the hind legs in the shape of a horseshoe along the heel, And an outsole including a grip member disposed on the front sole after the first stiffener.
In a preferred embodiment of the present invention, the hardness of the bottom layer is characterized by an outsole that is lower than the first stiffener and second stiffener and higher than the grip member.
In a preferred embodiment of the present invention, the stiffener comprises a metal, and the metal comprises steel, copper or aluminum.
In a preferred embodiment of the present invention, the grip member has a different hardness between a toe side portion and a middle foot side portion of the wearer.
In a preferred embodiment of the present invention, the grip member has a different hardness at the large toe side and the small toe side of the wearer. Preferably, the hardness at the large toe side is stronger than the hardness at the small toe side.
In a preferred embodiment of the present invention, the first stiffener narrows the thumb toe portion of the wearer so that the toe portion of the wearer is wider, and accordingly, the thumb toe portion is wider than the young toe portion.
In a preferred embodiment of the present invention, the first stiffener forms a sharp toe box to provide the support of the climber at the edge or pocket of the rock wall.
Further, the present invention is characterized in that an elastic band attached to the bottom of the sole and the side of the upper is integrally formed, and the elastic band catches the foot by the shoelace of the upper or the bellows means of the upper.
The stiffener according to the present invention provides a stiffener to reinforce the holding force against the hold, particularly to reinforce the hook, hook or heel hook, and to provide a grip member to reinforce the grip to the hold, It provides a sole that improves comfort compared to conventional rocking, protects the wearer ' s feet, allows the rock wall to stick to the rock, hold and pocket, and allows the climber to smooth the climbing motion.
It also provides an integral elastic band to hold the foot well to protect the wearer ' s feet and provide forefoot adhesion.

In general shoes, especially shoemaking, the shank is part of the support structure between the insole and the outsole, which plays an important role in reducing the load caused by the wearer's feet and rock during climbing in the hiking. Generally, the shank is made of steel, and the secondary shank is often made of a rigid material, such as glass fibers or Kevlar, which have low thermal conductivity. The stiffness properties of these materials help prevent damage to the wearer ' s pores or stones. The shank also supports the force, prevents distortion, maintains the shape and supports the shape. To do this, the shank must be provided through the midsole.
However, in the embodiment according to the present invention shown in Figs. 1 to 4, there is no shank in the middle sole. Therefore, in the present invention, when the technique such as jamming, move, oppoistion, etc. is applied, there is a fear that the rocking is distorted and the foot is distorted accordingly. Therefore, in order to protect the foot, And the
