Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to footwear comprising a hemmed sole and an abrasive sole (sole unit with two fixed upper parts).

PRIOR ART Shoes of this type known so far have used soles with greater elasticity and less elasticity.

This is mainly caused by a pad (-) between the hemmed sole and the abrasive sole, preferably made of foamed plastic, so that the foot remains in contact with the ground during one cycle of movement. !+- This pad acts as a kind of shock absorber for the foot C- which has to carry the weight from the body.

Such pads act like passive shock absorbers whose purpose is to protect the bones, joints and blood cells of the foot and leg; (When there are two (-exposed to great pressure (-exposed).

This cushioning mechanism also provides good contact between the sole of the foot and the sole of the shoe, as the foot sinks slightly into the sole of the shoe, minimizing surface pressure.

Object of the invention The object of the invention is to maintain its good properties, such as low surface pressure, adequate shock absorption, and yet to ensure that the compression of the sole contributes as much energy as the foot takes off. It can be used to improve the blood circulation of the legs (to have the effect of increasing blood circulation), and to improve this bottom.

Structure and Effects of the Invention An object of the present invention is to provide a bottom unit (two elastic ribs Y), and to prevent wear if the elastic ribs run transversely to the center line C of the bottom, and if there is a hemmed bottom. These elastic lips ( : The shock absorption and contact generation characteristics of the bottom are maintained, and C2,
While these ribs are straight (upwards and forwards of the slope), a kind of slurping effect is obtained from the ribs as pressure is applied to the 7 legs at once, and this pressure is applied at the time of take-off, that is, the so-called take-off stage. The compression of the ribs is therefore not a passive shock absorption, but rather an accumulation of the energy released during a take-off. In this way, the energy is utilized to the maximum extent to the benefit of the user. Sara(-1) Continuous undulations (undulations) from the heel part to the upper part,
The alignment of the ribs is caused by the release of the ribs, and this undulation has the effect of increasing blood circulation in the legs.

Claim 2: 6: When the described method provides an inclination of about 40°, a very good elastic action can be obtained.

As indicated in claim 3, co-molding of the rib and the wear sole (double 9) results in a joined body with the advantage of mass production.Claim 4 Item I
: As shown, effective elasticity can be obtained by separating the ribs from the wear bottom.

The structure shown in claim 5 (2. By restricting the placement of the opposing ribs, soft and comfortable elasticity can be obtained. 0 Claim 6 (1) As stated (2) The ribs should be provided with this lip bottom (2) so as to be able to provide the most advantageous shock absorption and elasticity (- Its dimensions can be determined by:

Finally, C2. Claim 7 (1) It is advantageous for the sole to be made of an ether-based polyurethane material, thereby avoiding the sticky surface of the ribs, This enhances the elastic properties of the ribs.

The invention will be further described with reference to M-planes.

The bottom unit is shown in a somewhat enlarged sectional view taken in the direction l-ll1lil in FIG. made of things. There is a wear bottom 2 provided with a number of lateral recesses on the lower side C''' of this edged bottom, and on its top side (2);
make. These lips are inclined at an angle of about 40° to the edged sole (2), but this angle can be varied as will be explained later.Finally, the wear sole 2 is fixed to the rib-sole (2).

FIG. 3 shows a cross-sectional view of the bottom taken in the direction of line 1--1 of FIGS. 1 and 2. FIG. It is clear that the wear sole 2 advances upwardly around the lips 1 and encircles them. This worn sole is rounded along its outer side 10 (along the entire circumference of the sole).

Furthermore, the C-rib li extends in the longitudinal direction (-) into a gap 9, which is separated from both side edges of the worn bottom. Provides good control over the edges of the lip and the tendency to center the foot in proportion to the sole and the wear of the sole and lip, preferably made by an ether-based polyurethane molding (Y) And on the surface of the reply, as explained later,
A sticky film is obtained which has a two-pronged effect on the elasticity of the lip.

Since the air space between each lip is compressed and thus increased, effective ventilation of the shoe is obtained, and the space or spaces 9 (e.g., FIG. When a conduit or opening (1) passing through the edged sole (3) is provided, the compression of the air is forced up the underside (2) of the sole of the foot. Arranged evenly (bi-distributed) in the necessary limited area.

Where there is simply a rib on the abdominal part of the heel 5, there is a space 9 (
Two interconnecting conduits can be made that are continuous on the underside (two fronts) of the ventral part of the foot 7 where the outer surface 11 of the edging sole is placed.

The inclination of the lip is caused by the fact that this lip is compressed by downward and backward directed pressure and is thereby released when the foot leaves the ground (a kind of spring effect). That will happen.

Due to this compression of the lip, and therefore the accumulation of energy, the take-off energy is released when the foot leaves the ground and does not end until the lip returns to its unloaded state (2,
To contribute (secondary).

The size of the ribs that are compressed by this continuous movement from the heel to the toes and create a hemmed sole (a kind of undulation) that has the effect of increasing blood circulation at the bottom of the foot. When deciding (2) is one of the things that determines the height elasticity of this lip, the forward line of the foot must be taken into consideration.Other factors are the distance of 1 m of the lip and its angle α. The elasticity of the material is important.

In order to provide the best operating conditions for each leg (−
For example, to support the torsional action at the beginning and end of walking, it can be done (1+1+3'f).
: This means that the turtle is guided through the advance line 4 indicated by the dashed line. Therefore, the height of the lip is made larger on the right side than on the left. For example, it has a height of 1B (for example, the height of the general lip is 15 mm). In this way, the remaining edge of the bottom around the periphery of the forward line is also subjected to a large external force. This results in both sex and suspension.

This sole is configured to have the least surface pressure and the largest contact area between the sole of the foot and the sole of the shoe.

As the foot sinks more or less into the sole, the load C
: The overall elasticity of the sole means that the contact surface between the sole and the sole of the shoe should be increased overall. In addition, the lip with an air space increases the compressive capacity of the bottom, and the maximum energy is stored in the compressed lip. C can be formed at different angles to the center line a-B+2 of the two sets in order to satisfy the characteristics.In this way, for example, it is possible to compensate for lateral loads of different strengths and in different directions. can.

According to the invention, this sole creates conditions according to the best utilization of the elastic action of the muscles.
