Description

Sole for shoes or sandals

The invention relates to a sole for shoes, as they will in general for shoes of different categories using, for example for street shoes, sport shoes, light hiking shoes or sandals. For long-term considerations, has proved that occur during walking and running

Shock loads are still being transmitted by the predominantly used on shoe soles damaging way on knees, hips and spine.

As is known from DE 20 2007 001 915 Ul a shoe insert known which consists of a resilient base body, on its underside in the central area, an elastic molded body is arranged, the remote from the main body side is convex, and the function of a

Abrollkissens takes over. Here, the elastic body has a higher degree of hardness than the resilient molded body, wherein on the upper side of the base body an anatomical foot bedding is formed. This shoe insert located in the inserted state the lower side not on the flat surface of the shoe insole, but rather fits only by the weight of the carrier thereto and to the longitudinal curvature of the foot. Thereby to produce a similar effect as an externally mounted on the sole metatarsal the insert inserted in the shoe. By the eventual strength of the shoe or its sole and the high elasticity of the molding such a rolling effect is probably the most not or not sufficiently achieved.

In the KR 100 825 433 Bl a sole assembly for Masai Walking Shoes is described which consists of three layers of substantially, an upper harder midsole, a soft intermediate layer and an outer sole. In the hard layer is a stiffening and

Spring plate incorporated. In addition, it has in the rear region on a lower mounting Chung, in which a corresponding convex bulge of the soft intermediate layer is flying. The underside of the sole structure is relatively strong curved as a whole, whereby a strong

Rolling and rocking is possible, but with insufficient stability and pressure distribution.

The DE 201 07 343 Ul discloses a running shoe sole with elastic material, in its lower side region outsole stiffeners are incorporated, which, however, only in

The heel and the central region extend.

EP 0214431 Bl is shown in a sole assembly for athletic shoes, wherein the three layers or portions are provided between an upper intermediate layer and the lower outsole, namely, a resilient heel portion, a flexible toe portion and therebetween a wedge-shaped harder core portion. However, this one uncoiling paddles is quite possible a stable secure distribution of pressure on the entire foot.

In WO 2010/136 513 Al, a composite insole is described which consists of an upper hard tub, a soft intermediate layer with a hard, downwardly concave ausbuchenden hard use and an outer sole. In the central region is between hard and soft use

Intermediate layer has a stiffening and plate spring inserted to Verbessemng the spring action of the sole. However, the foot-side pan does not have sufficient rigidity to hold the elastic composite sole. Finally, US 4,241 523 shows a sole structure having a foot-side hard pan, hard on its underside, down widely curved arches in the heel and the ball region are present. These are filled with a soft plastic material, this plastic also fills the toe area in a slightly pointed shape of the front and the entire structure is covered with the underside of an outsole. Although it can be very extensively unrolled and rocked hereby, but without sufficient stability and support of the foot.

The present invention therefore has for its object, a sole for shoes or

indicate sandals, through which the spring and rolling action improved, at the same time supports the natural step and the pressure is optimally distributed to the entire foot area. This object is achieved by a sole according to Claim. 1 Advantageous developments of the invention are specified in the subclaims.

Accordingly, the sole according to the invention is a layered composite and consists in arrangement to one another from a rigid insole, an insert made of a hard or less soft plastic material, which extends in the central region of the sole is downwardly convexly curved, and directly in contact with a subsequent soft intermediate layer. The apex of the hard insert is approximately equal to the breakover of the shoe sole. The

The intermediate layer consists of a soft plastic material, extends over the entire length of the sole, and has in the middle area of ​​the sole to form a complementary concave recess of the hard insert. The next sole layer, a lower rigid support plate is present, which also extends over the entire length of the sole, where finally a composite follows the downward final outsole.

It is advantageous if the rigid insole defines a planar surface on its upwardly facing side, extends over the entire length of the sole and is composed of hard, substantially flexurally rigid material. In this downwardly facing longitudinal ribs the rigid insole in the central region of the composite sole or in the region of the hard insert is arranged with a plurality of side by side, be provided, preferably in the kind of fish fins. Thereby, the bending stiffness of the insole is raised accordingly in the central region of the sole. , It is also advantageous if the hard insert is made of one piece or of several parts, or is designed as a plastic frame which is in turn filled with elastic balls as

Rubber balls or rods. The frame of the insert may have an upper planar wall and a convexly bulged bottom part, wherein the lower part is centrally separated by a slot into two curved resilient arms. By the nature and the number of resilient balls, which are incorporated in the frame, the spring action of the arms of the frame is defined.

Sehl- is positive that the soft intermediate layer has a flat top, in which a concavely curved recess is recessed for receiving the hard insert. The underside of the intermediate layer is also formed at least in the middle region of the sole and substantially in the rear region of the sole plane and parallel to the upper side, wherein in the front region of the sole a long upsweep is present. This longer curving forms a front wedge-shaped narrowing of the intermediate layer and thus the entire layered composite of the sole, so that preferably the occurrence of the (shoe) tip of the heel in a normal shoe at a height of about 5 cm offset from the bottom located. Optionally, where a short rounding or curving be incorporated at the outer end of the rear portion of the sole.

Furthermore, it is particularly advantageous when the lower rigid support plate for

Support of a natural step is provided with at least one narrow, about 0.5 to 2 mm wide slit-shaped transverse and a similarly sized longitudinal interruption, whereby a plurality of plate members next to and / or behind the other are formed. The longitudinal interrupt has an elongated S-shape extending in the longitudinal direction along the pass line, is the back continuous open and closed front. The two cross-interrupts are each provided between the heel or rear area of ​​the sole and Fußgewölbe- or middle region of the sole, as well as between the latter and bale or front region of the sole, whereby each adjacent pair of rear plate portions, two middle plate members and a front plate member are formed. The interruptions of the support plate in

Thickness direction of open or at least partially thin by webs or

Layers of material in the manner of film hinges elastically connected to each other. Generally, the power curve of the force application point in the X-Y coordinates of a Bodenreaktionski aftmeßplatte when it unrolling of a foot is meant by the term "transition line". The exact possibilities and procedures for determining a transition line known in the art and will not be explained here. The cross-breaks the rigid support plate allow, among other things, that the Abrollbzw. Abknickvorgang between the ball and toes during walking and running is not impaired.

The rigid support plate may also be provided with a bead-shaped longitudinal rib for supination-support and along the rear outside or of the outside rear plate member have a bead-shaped longitudinal rib for pronation support on each other along and close to the front inner side or the front plate member.

The rigid support plate, but also the upper rigid insole, may consist of a

Plastic plate, a fiber composite sheet having a multilayer structure, or a combination thereof exist. The multilayer structure of the fiber composite sheet can be made of which from glass, aramid or Carbonfasem or combinations thereof. It is particularly preferred when the fiber composite sheet used is made of carbon fibers.

The layer of the composite underside final outsole z can. For example, be a rubber sole, preferably from a polyamide, polyurethane or the like having a thickness of about 2 mm. It can also be used ethyl vinyl acetate (EVA).

It is advantageous if the ratio between the Shore A hardnesses of the material of the hard insert and the soft intermediate layer is about 2: 1. Preferably the hard plastic insert has a Shore A hardness of about 45 to about 50 and / or the soft plastic intermediate layer has a Shore A hardness of about 20 to about 25. In addition, the upper rigid

Insole a hardness of about 80 Shore A, and even more preferably about 100 Shore A and the lower rigid support plate having a hardness of at least 80 Shore A. It is understood that the over- or under-stacked composite parts of the sole are inseparable, z. For example, by gluing, whereby the positive

add properties of the individual layers and sole results in an optimally equipped in every way in their Funlction sole. The rigid insole is particularly advantageously be used in conjunction with soles for sandals or shoes. In particular, ensures the rigid insole which substantially does not deform themselves, also in conjunction with the rigid divided support plate, that the foot remains at each step in the same position. Thus, the interaction of the soft intermediate layer of the hard insert and the rigid (preferably divided)

facilitates support plate and the natural Stepping Abrolibewegung of the foot is substantially ensured by the front curve or curving of the sole unit. The advantages achieved by the present invention can be summarized as follows: The interaction between upper and lower rigid insole rigid support plate leads to a particularly high stability of the whole sole. In addition, results from the

Interaction of the two rigid plates with the intervening soft plastic of the intermediate layer has a damping and / or spring action. In the presence of the

Support plate and the transverse transition line interruption, with corresponding

Support ribs and / or the front intensifying slight curvature or curving of the sole in the toe area, is also an advantageous effect on orthopedic knee, hip and spine achieved.

The composite of soft interlayer, hard use, rigid support plate and rigid insole distributes the pressure perfectly on the whole foot surface. In addition, the front and rear area of ​​the sole is more compressed than the central region of the sole which includes the hard insert so that during walking or running a rolling around the breakover occurs at the same time an aesthetically appealing shape of the sole without excessive buckle is maintained. Therefore, the foot is bent as usual.

The composite sole according to the invention also allows, defined for each step, a

Is available Abrolleigenschaft the wedge-shaped tip total while walking creates a rocker effect or supported so that walking becomes easier.

The shock loads that occur during walking and running are not or only minimally transferred to the knee, hip and spine. Thus, viewing or langzeitigem wearing shoes with soles invention, damage from impact loads can be virtually eliminated in long-term. The sole is suitable due to their particularly high stability for use with any footwear including with light shoes and sandals.

Moreover, a shoe can be made both in Strobel and tweaked in design of the inventive sole.
