Abstract

The shoe insert is provided with an anti-slip surface which contacts the sole area of the sock or stocking of the shoe wearer.

Description

The present invention relates to an insert for arrangement between a Shoe and a foot with leg clothing.

Shoe inserts can be used to warm the wearer's foot, Compensate for mismatches between the shoe and the wearer's foot, Absorb moisture from the wearer's foot and / or To avoid unpleasant smells.

When wearing leg clothing, especially tights, stockings, Knee highs and socks, this often occurs on one foot in a shoe Problem on that the foot part of the leg wear worn on the foot during of slipping in the shoe. Because of foot movements when walking Material of the foot part of the leg clothing, which is in contact with one hand the shoe and on the other hand in skin contact with the foot, in permanent Movement, causing uncomfortable wearing sensations and wrinkling and can therefore lead to uncomfortable pressure points.

To prevent the foot part of pantyhose and silk stockings from slipping in To avoid a shoe, it is already known from DE 200 00 635 U1, to provide the sole part of the stocking in question with anti-slip elements. These anti-slip elements are integrated in the sock in question, which has the disadvantage that the anti-slip elements on everyone stocking used by the wearer must be arranged and that the Anti-slip elements are visible when the stocking is outside of the shoe will be carried.

The present invention is therefore based on the object of an alternative Possibility to create the stability of leg wear within to raise a shoe.

This object is achieved by an insert for arrangement between one shoe and one foot covered with leg clothing, the one non-slip surface facing the foot during use of the insert having.

The anti-slip surface has a high static friction in relation to that with it Area in use of the insert in contact materials of the legwear so that the foot part of the leg wear when wearing the shoe maintains its position relative to the deposit. This way it will slip the material of the legwear in the shoe as well as a wrinkling of the Prevents leg wear.

In a preferred embodiment of the invention it is provided that the Inlay in addition to the anti-slip surface facing the foot Use of the insert has the additional anti-slip surface facing the shoe. This lower non-slip surface has a high static friction on the material of the insole of the shoe, so that the insert during of wearing maintains their position relative to the shoe. That way the insert slips in the shoe and the insert folds prevented.

It has proven to be particularly favorable if the anti-slip surface is made of a material comprising an elastomer material is formed.

To make the insert inserted into the shoe appear particularly inconspicuous leave it, it is advantageous if the anti-slip surface from a transparent Material is formed.

In a preferred embodiment of the invention it is provided that the Anti-slip surface made of a material comprising a silicone material is.

The silicone material can, for example, be a one-component silicone (for example with acetic acid as solvent) or a two-component silicone include.

The anti-slip material that makes up the anti-slip surface facing the foot is formed, preferably with cotton as a friction partner a coefficient of static friction of at least about 0.5, in particular of at least about 0.9.

The anti-slip material that makes up the anti-slip surface facing the shoe is formed, preferably with leather as a friction partner a coefficient of static friction of at least about 0, 5, in particular of at least about 0.9.

In a special embodiment of the invention it is provided that the Anti-slip surface is provided with an embossed structure. The embossed structure includes bumps that match the surface of the legwear that is attached to the anti-slip surface, can interlock and thus the static friction between further increase the anti-slip surface and the leg clothing of the foot.

The insert can be produced particularly easily and inexpensively if it is advantageously provided that the insert comprises a carrier material, which is provided with an anti-slip coating.

For high static friction with both the legwear and the insole To achieve the shoe, it can be provided that the carrier material is provided on both sides with an anti-slip coating.

The carrier material can, for example, be a film made of a plastic material include.

In particular, it can be provided that the carrier material is made of a film Includes polyamide.

The same or functionally equivalent elements are the same in all figures Reference numerals.

A set of inserts 102, designated as a whole by 100, shown in FIG. 1 is an insert 102a for a left shoe, the outer contour 104 the outer contour of the tread of a left human Corresponds to the foot, and an insert 102b for a right shoe, the Outer contour 104 of the outer contour of the tread of a right human Corresponds to the foot.

As can be seen from FIGS. 2 and 3, each of the inserts 102a, 102b as a carrier material 106 is a textile band 108 made of cotton fibers, for example or can be woven from polyamide fibers.

The band 108 has a thickness of, for example, approximately 500 μm to approximately 600 µm and is 110 on its top with an upper anti-slip coating 112 and on its underside 114 with a lower one Anti-slip coating 116 provided. The anti-slip coatings 112 and 116 have a thickness of, for example, approximately 150 μm each.

The top 118 of the first anti-slip coating facing away from the carrier material 106 112 forms an upper non-slip surface 120 of the insert, which in the use of the insert with the legwear, in particular a pair of tights, a stocking, a knee-high or a thin pair Sock, facing the wearer's foot.

The underside 120 of the lower anti-slip coating facing away from the carrier material 106 116 forms a lower anti-slip surface 120, which in the Facing the insole of the shoe.

Anti-slip coatings 112 and 116 are formed from a material which has a high static friction with those materials with which the insert 102 comes into contact during use.

In particular, it can be provided that the anti-slip coatings 112, 116 made of an elastomer material, preferably a silicone material, are formed.

A one-component silicone (with Acetic acid as solvent) or a two-component silicone come.

The mesh size of the textile belt 108 is in the first embodiment the insert 102 is chosen so small that the mesh openings of the band 108th are completely covered by the anti-slip coatings 112, 116, so that the insert 102 has a completely closed upper anti-slip surface 118 and has a completely closed lower anti-slip surface 120, which are both essentially flat.

The insert 102 has a total thickness so small that it is essentially has no dimensional stability, but is flexible and adapts to the shape of the insole of the shoe on which it is placed,

Due to the high static friction between the insert 102 and the insole of the shoe, the lower anti-slip surface 120 shifts in use the insert 102 is not relative to the insole of the shoe, so the Insert 102 maintains its position relative to the shoe and does not wrinkle.

If the shoe is worn, the leg clothing comes Foot tread surface in contact with the upper anti-slip surface 118 insert 102.

Due to the high static friction between the insert 102 and the material the foot part of the leg clothing maintains its position relative to the leg clothing the insert 102 and thus relative to the shoe. In this way, a Slipping of the material of the leg clothing in the shoe as well as wrinkling which prevents leg wear.

The anti-slip surfaces 118, 120 have a high static friction in relation on the materials in contact with these surfaces adhere to them Materials but not on, so that the legwear provided Can easily lift foot from insert 102 and insert 102 can easily be removed from the shoe if necessary.

The insert 102 is produced as follows:

First, a textile tape is made from, for example, a polyamide yarn a width of, for example, about 55 mm to about 50 mm.

The polyamide fibers used for this can be white or in any the desired color.

The tape 108 is then printed, for example with a label 122, which indicates whether the insert 102 for the left shoe or for the right shoe is determined, and / or with the manufacturer's brand.

Then the material of the anti-slip coatings 112, 116 in flowable form, for example by spraying or rolling onto the Top and bottom of the tape 108 applied.

After drying and, if necessary, curing and / or crosslinking the The insert 102 becomes anti-slip coatings 112, 116 along its outer contour 104 separated from the coated tape 108, for example by punching out or cutting out.

This completes the production of the insert 102.

A second embodiment of an insert 102 shown in FIG. 4 differentiates differs from the first embodiment described above in that that the textile belt 108 serving as carrier material 106 is not everywhere has the same mesh size, but rather areas 124 with smaller Mesh size and areas 126 with large mesh size, the are successively distributed over the belt 108.

In particular, as shown in Fig. 4, it can be provided that in a Section 128 of band 108 approximately square areas 124 of small mesh size and approximately square areas 126 of large mesh size in a checkerboard pattern are alternately arranged.

The meshes of the band 108 are in the regions 124 with a small mesh size so small that the anti-slip coatings 112, 116 the mesh openings cover completely so that the insert 102 is closed in these areas Has surfaces.

The mesh openings 130 are in the regions 126 of large mesh size however, so large that it does not have anti-slip coatings 112, 116 be completely covered. This creates within areas 126 Through openings 132, which extend from the top of the insert 102 to extend to the bottom through the entire insert 102 and a passage allow air and moisture through the insert 102.

Through these through openings 132 there is breathability of the insert 102 achieved. It is also possible through the through openings 132 to moisture to be removed from the leg clothing of the foot through the insert 102.
