DE10030678A1 - Shoe insole of flexible material has cover layer fastened as thin wooden sheet to bearer material and crisscross recessed along insole line. - Google Patents

Abstract

A thin wooden cover layer (2) is fastened (9) to the bearer material (8) at an ideal break point (5), the layer (2) recessed (3,4) in its wooden sheet starting from the upper side allotted to the foot. The recesses (3) run at right angles to the insole length (1) as against recesses (4) which lie in the insole length so the recesses cross one another. Recesses (3) are closer spaced in the break area (5) than the recesses in the insole parts either side of the break. The recesses (3,4) lie within the cover layer thickness or can pass through this (2).

Description

The invention relates to an insole made of wood with a flexible Backing material for footwear according to the generic term of Main claim.

An insole of this type is known from DE 43 23 399 A1. This Insole is made of several interconnected layers of wood and textile material, the upper - assigned to the sole of the foot - The top layer consists of a thin wooden sheet. The runs Grain direction of the upper cover layer in the longitudinal direction of the insole and the intermediate layer and the lower cover layer each consist of one textile material as a flexible carrier material.

The disadvantage here is the relatively complex structure of the layers and the thus reduced flexibility of the carrier material. There is also at such insoles there is a risk that at least those made of wood formed top layer in particular in the field of football through the Bending load while running forms a predetermined breaking point, the one Represents a risk of injury.

The invention is based on the object of an insole to create the type mentioned, the disadvantages mentioned avoids, which in particular allows good sweat dissipation and the risk of breakage at a predetermined breaking point is noticeably reduced.  

The object is achieved by the training features of Main claim solved. Further training results from the Dependent claims.

A first advantage of the insole according to the invention is therein justifies that at least part of the top layer consists of a thin Wood sheet is formed on a flexible carrier material and that the At least one top layer on the upper side assigned to the foot Has indentation within the thickness in the wood sheet. Through the deepening or depressions, the wooden sheet of the top layer becomes more flexible, in particular with an arrangement in the area of a predetermined breaking point, and at the same time preferably maintain the bond of the wood sheet by the Wells preferably end before the carrier material. In another Training, the wells are designed such that these are worked in all the way down to the carrier material. By both Training reduces the risk of breakage and the risk of injury and the liability of the insole can be extended.

It is also advantageous that at least one made from a thin wooden sheet formed part of the top layer is assigned to the foot at the top and continues to perform the function of perspiration and depending on selected wood, for example pine, beech or Cedarwood, in addition a possible odor nuisance is reduced.

The invention will be explained in more detail using an exemplary embodiment. The following schematically show:

Fig. 1 a first embodiment of an insole in plan view and sectional AA,

Fig. 2 shows a second embodiment of an insole in plan view,

Fig. 3 is a section AA of FIG. 2.

An insole 1 for footwear has a cover layer 2 , at least in part consisting of a thin wooden sheet. The cover layer 2 has an upper side 10 assigned to the foot. As is known, there is a predetermined breaking point 5 in the area of the ball of the foot, which occurs as a result of the bending load when the sole of the foot rolls off while running. The predetermined breaking point 5 often extends over the full width of the insole 1 .

The insole 1 has a continuously arranged carrier material 8 on the underside. The carrier material 8 preferably consists of an inextensible and flexible, ie, flexible, material. Flexibly elastic textile materials, scrim, fleece, felt or a flexurally elastic elastomer, for example a rubber, or rubberized textile material can preferably be used as materials. The carrier material 8 is connected directly to the cover layer 2 by means of an adhesive connection 9 , preferably an adhesive connection.

At least in the area of the predetermined breaking point 5 , the cover layer 2 is formed from a thin wooden sheet. In this embodiment, the top layer 2 has several depressions 3 in the area of the predetermined breaking point 5, at least transversely to the longitudinal direction of the insole 1 . The depressions 3 are preferably arranged at a parallel distance from one another in the top layer 2 made of a wooden sheet. In a further embodiment, at least in the area of the predetermined breaking point 5, in addition to the transverse depressions 3, there are also depressions 4 extending in the longitudinal direction, preferably at parallel distances from one another, in the cover layer 2 . arranged.

In an embodiment that is not shown, the depressions 3 , 4 are also arranged diagonally or diagonally intersecting (for example diamond-shaped) or in any other geometrical form individually or in combination.

The depressions 3 , 4 are worked into the cover layer 2 by a non-cutting or a cutting process, for example by cutting or milling. Preferably, the depressions 3 , 4 - starting from the top 10 - end in front of the adhesive connection 9 in the wood sheet, so that a fiber composite of the wood sheet is retained within the thickness in the cover layer 2 and at the same time the bending elasticity is increased and the risk of breakage is thus reduced.

Alternatively, to further increase the elasticity of bending, at least one of the depressions 3 and / or 4 - starting from the top 10 - is formed continuously up to the adhesive connection 9 with the carrier material 8 . The transversely arranged depressions 3 are preferably designed in this way. The fiber composite within the thickness is not or only partially guaranteed in the respectively selected recess 3 and / or 4 . The bending elasticity is preferably ensured by the carrier material 8 .

In an embodiment according to FIG. 1, the insole 1 is formed over the entire area (over the entire insole 1 ) with depressions 3 , 4 in the cover layer 2 . In the area of the predetermined breaking point 5, at least the transversely arranged depressions 3 are preferably arranged at a closer distance from one another than the depressions 3 in the partial sole regions 6 , 7 in order to increase the elasticity in bending.

In an embodiment according to FIG. 2, the insole 1 is formed only in the area of the predetermined breaking point 5 with transversely arranged depressions 3 , if necessary also with longitudinally arranged depressions 4 . In a front partial sole area 6 assigned to the tip of the foot, a cover layer 2 made of a thin wooden sheet (without depressions 3 , 4 ) is adhesively connected to the carrier material 8 by means of connection 9 . In a rear partial sole area 7 assigned to the heel, a cover layer 2 made of a thin wooden sheet (without depressions 3 , 4 ) is adhesively connected to the carrier material 8 by means of connection 9 . In one embodiment, the top layer 2 of thin wood sheet is arranged individually in relevant areas (predetermined breaking point 5 , partial sole area 6 and 7 ).

In a preferred embodiment according to FIG. 3, the cover layer 2 is formed in these areas from a (one-piece) continuous sheet of wood and the depressions 3 and 4 are made within the relevant areas within the thickness.
