Description

Climbing boots with elastic heel

More particularly, the present invention relates to a shoe sole with a stretchable heel portion. More particularly, the present invention relates to a shoe sole provided with a heel portion formed of a material having elasticity for rocking, The present invention relates to a shoe sole with a stretchable heel portion which is made to adhere to the surface of the foot regardless of the shape of the wearer's heel even after wearing the shoe so as to improve usability and gripping feeling during climbing.

Rock climbing is also important in terms of strength and skill, but it is important to wear equipment that matches your style and type of rock climbing.

One of the equipments to be worn when climbing rocks is rock climbing, which is specialized for rock climbing. It is the equipment that wears on the wearer's foot without wearing socks.

In recent years, the company has developed a window with better performance and uses T.D.R. (Thermo Dynamic Rubber), a non-rubber petrochemical.

However, there is a problem that the material is hardened and hardened as time passes, and the function is deteriorated.

Therefore, it is not only difficult to fit the wearer's feet, but also wears rock climbing even though the size is finely deformed to such a degree that the hardened hardened rock wall is broken over time.

For example, the stiffness of the shoe window can be classified into two types: rocking, climbing, climbing, climbing, climbing, climbing, It is easy to move around with a falling edge, and a soft, stretchy window is excellent in friction action that requires strong friction, so you should choose a rock type that suits your style and situation.

In addition, the rock wall has various shapes such as rounded, angled, and pointed ends, and its usage is different according to the climbing motion.

Nowadays, rocks tend to be bent in a flat shape so as to gather strength in the soles of their feet, and they are changing so as to match the structure of the foot as much as possible.

Therefore, as a prior art relating to the rocking with a stretchable heel portion, as shown in Fig. 7 (a), "friction mountaineering shoes" (hereinafter referred to as "Prior Art 1") of European Patent Publication No. 0933033, An insole, a toe and a heel cap formed by coating a resilient material and the coating also includes a corresponding seam of the top and insole and an insert for the remaining seam, which is covered by the opposite side edges of the middle sole to form a heel loop The present invention relates to a friction mountaineering shoe having a protrusion and an end heel loop and an intermediate loop.

As another prior art, as shown in Fig. 7 (b), a method of manufacturing a size correction pad for exclusive use on a rock wall (hereinafter referred to as "Prior Art 2") of Korean Patent Laid-Open Publication No. 10-2015-0029603. ) Is a method of inserting a band-shaped ring into a mold made to fit the concave portion of a rock wall of a rocking heel and then pouring a silicone material or a highly elastic rubber material into a mold, And a method of manufacturing a size correcting pad for exclusive use of a rock wall.

The prior art 1 still includes a problem that the elastic material is coated on the upper part of the friction climbing shoe so as to secure the elasticity of the friction climbing shoe but to be close to the heel of the wearer. Prior art 2 solves the problem But this correction pad is not easy to manage because it needs to be separately inserted into the rock wall to close the rock wall and the wearer's heel, and gives a sense of heterogeneity between the foot and the rock wall.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a configuration and operation of a rocking structure to which a stretchable heel portion of the present invention is applied will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a first state of the present invention, which is a first embodiment of the present invention, and FIG. 2 is a perspective view of a second state of the present embodiment of the present invention.

FIG. 3 is a block diagram showing a configuration of the present invention. FIG. 4 is a cross-sectional view of a rocking structure to which a stretchable heel portion of the present invention is applied.

As shown in Figs. 1 to 4,

1. A shoe sole (1) to which a heel portion having elasticity is applied,

(100) for protecting the front and middle parts of the wearer from the outside;

A stretchable heel portion 200 coupled to the upper portion 100 and protecting the rear portion of the foot;

An Achilles tendon rubber land 300 that assists the stretchability of the heel portion 200 and improves the degree of adhesion; And

And an outsole part 400 attached to a bottom surface of the upper part 100 and the heel part 200,

The heel portion 200 is formed in a 3D shape.

At this time, the uppers 100,

An upper (110) made in a paw shape that surrounds and protects the feet from the outside;

A first shoe lace 120 positioned above the upper 110 to fix the upper part of the shoe of the wearer;

A first shoe lace fixing part 130 located at the upper part of the upper part 110 and fixing the first shoe lace 120 inserted therein; And

And a vera 140 coupled to the inside of the upper part 110 and protecting the wearer's foot from the outside with the upper part 110. The upper part of the upper part of the upper part 110, And a shoe lace (150).

In addition, the heel portion 200,

Shaped into a 3D shape,

A first zone 210 that assists in the insertion of the wearer's heel when worn and is relaxed / contracted in two directions before and after the wearer's heel assisting and protecting the heel of the wearer's wear; And

And is formed so as to extend from the lower end of the first zone 210 and corresponds to the shape of the heel deformed by the movement of the bottom of the wearer's heel during climbing of the rock after wearing so that the wearer's still- A second zone 220 that is relaxed / contracted in four directions: front, back, left, and right; and is made of a knit or rubber fiber material.

As described above, the heel portion 200 is divided into the first and second regions 210 and 220 in different roles, but must be formed into a 3D shape having adhesiveness and stretchability. The heel of the wearer is deformed correspondingly to the shape of the heel varying according to the wearer when the rock wall is pressed by the foot during the rock climbing in accordance with the weight and skin characteristics of the wearer, So that the foot can be protected against the heel.

In other words, conventionally, in order to satisfy the large and small difference in the size of the foot ball and the heel according to the foot type (foot shape) of the wearer, at least four kinds (foot size / (The ball small / the heel of the foot, the ball small / the heel of the foot), and the problem that the rock wall of the foot should be produced by the size of the foot. .

In addition, although at least four types of conventional rocking shoes are manufactured in various categories, they do not provide a perfect grip for the wearer.

This is because the conventional rock formation is formed of a material having stretchability only at certain parts such as the upper part of the foot (foot), and the front part of the foot and the heel are made of a material having relatively no elasticity. And it does not satisfy the shape of the foot deformed according to the movement. Therefore, it causes the fatigue of the foot when worn for a long time and the elastic material does not correspond to the movement of the wearer during the climbing of the rock and the tendency of the rock wall to depart from the heel occurs It has a problem that can lead to a safety accident.

On the contrary, the present invention can satisfy the unique foot type (foot shape) of the wearer due to the heel portion 200 formed in the 3D shape formed by the first and second zones 210 and 220, The heel 200 is closely adhered to the heel of the wearer due to the deformation of the heel due to the movement of the wearer, thereby reducing the fatigue of the foot and maximizing the grip.

Also, as shown in FIG. 5, the Achilles' heel rubber land 300 further maximizes the degree of contact between the heel portion 200 formed in the 3D shape and the wearer's heel.

Another reason for molding the heel portion 200 separately into a 3D shape is that the process in which the conventional rocking is sewn in 2D and is fitted to the last (shoe model frame) The heel can not be completely covered, and at the same time, an unnecessary space is not formed between the heel and the rock wall. In addition, since a uniform product can not be produced due to errors in sewing, And the two regions 210 and 220, thereby solving the problem of a grip which can not be solved in 2D.

At this time, the heel portion 200 is made of a knit or a rubber fiber material, so that the heel portion 200 can be brought into close contact with the heel portion of the wearer without any sense of sheer.

The loops 900 are coupled to the upper portion of the heel portion 200 and are in the form of a ring that assists the wearer's feet to be easily inserted when the user wears the rocking shoes. As shown in FIG. 4, 100 and the heel portion 200 are combined with each other and the bottom window 410 is attached to the bottom surface thereof. The floor window 410 is then bonded to the forefoot portion in a region where the middle portion is located to protect the wearer's foot and improve the durability of the wall.

The reason why the position where the fastening fabric 420 is engaged is limited because the flexibility of the wearer's foot is secured.

If the fastening fabric 420 is coupled long enough from the forefoot to the hind part without considering the situation where the wearer has to bend the feet and the situation where the wearer has to bend the feet horizontally, the degree of freedom of the angle of the wearer ' So that fatigue easily becomes a factor to raise the wearer's foot.

In contrast, the forefoot midsole 430 and the hindquarter midsole 440 are respectively bonded to the forefoot and hind legs of the rock bottom surface, the bump rubber land 450 is joined to the distal end of the rock wall, And is attached to the heel portion around the midsole 440.

At this time, the bottom window 410, the fixing fabric 420, the forefoot midsole 430, the hindquarters midsole 440, the vamp rubber land 450, the heel rubber land 460, the outsole 470, Is an element that is coupled to the bottom surface of the rock wall to protect the wearer ' s soles from the outside, assisting the movement and enhancing the durability of the rock wall.

That is, according to the present invention, by applying the heel portion 200 formed in 3D in the shape of the heel in addition to the organic coupling relation of each component, the upper, middle, and lower heel portions of the heel The pressure and elasticity of wrapping the heel, and the tendency of the heel of the rocking in the bracket posture when climbing rocks to naturally peel off, significantly reduce the adhesion of the wearer's heel.

As described above with reference to FIG. 6 and FIG. 6, when the heel portion 200 is formed in a 3D shape, for example, the first region 210 uses a yarn for increasing the pressure in the region where the Achilles tendon moves inward and outward, The bottom of the heel of zone 2 (220) is supposed to be elastic so that when the weight of the person is lifted and the heel's flesh spreads sideways, the heel should be stretched together with the heel so that the whole heel can be continuously adhered to the rock .

Therefore, the present invention having such a configuration can increase the degree of adhesion with the foot surface, thereby reducing the fatigue of the feet even when worn for a long time, and protecting the wearer from safety accidents.

The heel portion 200 formed in the shape of a 3D among the constituent elements of the present invention is an ergonomic design that is formed in a three-dimensional shape or has a curved shape that is unique to the human body For example, a knitting machine (a three-dimensional molding machine) manufactured by STOLL.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined in the appended claims.

Accordingly, the invention may be embodied in many other forms without departing from the spirit or essential characteristics thereof, and therefore, the embodiments of the present invention are to be considered in all respects as illustrative and not in a limiting sense.

The present invention relates to a shoe sole formed by applying a 3D shape to a heel so that the shoe can be brought into close contact with the heel of any wearer, It can be applied to contribute to the promotion of industry.
