靴底部に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention accommodates the natural movement of the foot by providing a weakened section in the arch of the foot to reduce torsional stiffness around an axis extending generally in the longitudinal direction of the shoe. It relates in particular to a sole of a sports shoe, in which the front sole part is twisted relative to the rear sole part about said axis.

の側縁から内側に延び且つ剛性の少ない充填材料
を充填した凹部を設けることができる。(Conventional technology and its problems) When the foot moves naturally, around the cuneiform bone, that is, at the top of the arch of the shoe sole, between the front part of the foot and the heel, the center is centered on the axis that lies approximately in the longitudinal direction of the foot. A twisting action occurs. Taking this torsional movement into consideration, it is biomechanically important to intentionally create a weak section in the arch of the sole of the shoe, and to twist the front sole part relative to the rear sole part about the axis that exists in the approximately longitudinal direction of the shoe. It is known (German Patent Specification No.
No. 804901). Such a thin section is achieved by reducing the thickness of the sole or the arch of the shoe sole, but it is desirable to leave a central protrusion extending approximately in the longitudinal direction of the shoe ( German published specification DE-AS 1485804), or a recess extending inwardly from the side edge of the sole and filled with a less rigid filler material can be provided.

顕著となる。 A weakened section to reduce the torsional stiffness of the arch of the shoe sole also necessarily results in a reduction in the bending resistance of the sole about the lateral axis. This also uses the above idea to create a wedge-shaped longitudinal sole to prevent the sole from wearing out in the arch area of the shoe with the heel member, and this design provides a firm support surface for the arch area of the foot. It was proposed that it be established. However, especially in the case of sports shoes, the torsional performance of the front sole section relative to the rear sole section, which is basically desirable, does not allow the sole to flex due to the torsion of the arch section and can easily bend in this section. It has been found that in some cases this results in inadequate guidance and retention of the foot. The reason is that the foot has excessive free movement in the metatarsal region. This is especially true when a runner's foot hits unavoidable bumps, such as when walking or hiking, running wildly, jogging, etc. This becomes more noticeable when there is a lack of .

つて曲がるときに生ずる曲げ運動に関係がある。 Therefore, according to the invention, the arch of the shoe sole is strengthened by a reinforcing device so that it does not bend around an axis transverse to the longitudinal direction of the shoe, and the increase in bending resistance in this case is particularly caused by convexity. It relates to the bending motion that occurs when the sole of the shoe bends downward, that is, toward the ground contact side of the sole.

たストリツプ状エレメントが存在する。 It is particularly advantageous to keep the reinforcement device, which should have torsion resistance and extend in the longitudinal direction of the shoe, close to the ground side of the sole. This element need not have any bending strength. The reason for this is that the reinforcing effect of the sole is obtained by the inextensibility or only slight extensibility of the tensile resistance element and by its placement under the "neutral bending fibers" of the sole. It is a significant advantage that the tensile-resistant and, for example, strip-shaped element has no torsional rigidity of its own and therefore does not have any adverse effect on the desired torsional performance of the front bottom part relative to the rear bottom part. Therefore,
By using such a tensile resistance member, the bending strength of the arch of the sole can be controlled within a wide range without affecting the torsional rigidity of the arch of the sole. Another important effect is that the reinforcement effect of the tensile resistance device can be considerably reduced compared to reinforcement devices that themselves have bending strength (e.g. steel shank springs), which is particularly important in sports shoes. It's important. A material with high tensile strength and almost no extensibility, high strength and very light weight.
For example metal wire, carbon fiber and glass fiber,
Plastic wires and strip-like elements made of such materials exist.

常に接近して配置される。 In a particular embodiment of the invention, the zone of weakness that reduces the torsional stiffness in the arch of the sole extends laterally or diagonally (sloping forward or backward) medially from the edge of the sole in the longitudinal direction of the shoe. It is a recessed part extending to a protruding part. The protrusion extends approximately centrally between the side edges of the sole. Its shape is such that the tensile resistant element extends along the projection. According to this construction, when the sole is made of plastic material, as is customary, the tensile resistance element is embedded in the projection on its underside. The element can also be provided along the free lower surface of the protrusion, in which case abrasion soles fixed to the front sole part and the rear sole part do not bring the tensile resistance element into direct contact with the ground. In this way, the tensile resistance element is placed very close to the ground side of the sole.

な形状をしている。 Even if the reinforcing device is made by the above-mentioned tensile resistance element, it is embedded in the sole of the shoe over its entire length, thus transmitting forces over its entire length and providing a reinforcing effect. However, this is not always necessary in the case of reinforcing devices that are resistant to bending as well as those that are slightly resistant to tension, and it is important that both ends of the reinforcing devices are properly and firmly fixed to the sole of the shoe. It becomes a point. For this purpose, it is advantageous to fix the anchoring insert at the end of the reinforcing device, for example by embedding it directly in the sole of the shoe. The anchoring insert is shaped to resist movement in the longitudinal direction of the shoe in response to forces acting on it as the sole rolls.

and a contoured wear sole 2 in contact with the ground. The outer sole is the front bottom part 3 and the arch part 5
It is subdivided into a rear bottom portion 4. The soles extend inward from the outer and inner edges and slope diagonally forward.
It is subdivided into weak sections 6 and 7 consisting of several recesses. As shown in FIG. 3, the weakened sections 6, 7 extend within the sole to more than half its height.
Between the mutually facing ends of the weakened sections 6, 7, the intermediate sole 1 remains constant in its thickness, so that a projecting portion 8 passes approximately through the longitudinal center of the sole.
I will provide a. Due to the presence of said weakened sections 6, 7, the front bottom part 3 is torsionally "uncoupled" with respect to the rear bottom part 4. In other words, the front bottom part 3
can be twisted relative to the rear sole part 4 about an approximately longitudinal axis of the projecting part 8, this twisting corresponding to the natural movement of the human foot when it sways from side to side. , and thus assists in this lateral movement.

The reinforcing element 9 is a tensile-resistant, low-stretch plastic wire 91 (for example made of nylon) connected in parallel to form a flat strip, and a mooring insert fixed to the end of the wire 91. It has 92 and 93. Plastic wire 91 with a diameter of e.g. 1.5 mm
are fixed to the mooring inserts 92, 93, preferably made of plastic material, for example by embedding directly therein. Furthermore, the plastic wires 91 are connected to each other over their entire length. The mooring inserts 92, 93 are plate-shaped (FIG. 2) and have lateral legs 94. The anchoring inserts 92, 93 are provided with holes 95 through which the material of the midsole 1 can flow during the molding or shaping operation to embed the anchoring inserts in the sole.

The underside of the protruding part 8 along which 1 extends is arranged on the upper part of the grounding side of the wear sole 2. In the embodiment shown, the wear sole 2 is made of plastic wire 9.
1 exposed interruption or hole 10 in both parts of the sole, i.e. in both the front sole part 3 and the rear sole part 4. This ensures that when the front bottom part 3 is twisted relative to the rear bottom part 4, said strip formed by the plastic wire 91 is bent. However, the holes 10 are not necessary and the reinforcing element 9 and in particular the plastic wire 91 can be completely covered by the wear sole 2 in order to protect said wire 91 from damage.

る。 From the above explanation, the following becomes clear. The bending strength of the outsole about a transverse axis extending perpendicular to the protrusion 8 can be controlled by the stretch resistance of the reinforcing element 9. If you want to increase the bending strength of the sole, use plastic wire 91.
The number of strips and the width of the strips formed by them can be increased. It is also possible in principle to increase the thickness of the plastic wire, but care should be taken to avoid increasing the torsional stiffness of the sole in the arch region.

Instead of 1, other reinforcement devices with tensile strength can also be used. That is, the mooring insert 9
According to No. 2,93, a strip of glass or carbon fiber mesh, rope or cloth may be embedded in the sole in the same manner as described above. By choosing the width of the strip formed by such a fabric, the tensile strength and therefore the bending strength can be controlled within a wide range without significantly influencing the weight of the sole. . However, it is also within the scope of the invention to provide a flat metal strip with a correspondingly lower bending strength but with a significantly higher tensile strength due to its reduced thickness.
