Description

Shoe and method for manufacturing a shoe

Technical Field

The present invention relates to a shoe and a method for manufacturing a shoe. The invention is illustrated in connection with men's shoes, but is also advantageous for women's shoes or shoes for children.

Background

Many shoes, which are specific to a person's foot, have a sock-like structure that is capable of receiving the foot and resting on the sole. Shoes are often worn for many hours. The shoe should not unnecessarily limit the rolling motion of the foot while walking. In addition, the foot releases moisture which should be absorbed by the shoe and released to the surrounding environment.

Some known shoes are considered to be inadequate in terms of wearing comfort.

Disclosure of Invention

It is an object of the present invention to provide a shoe with improved wearing comfort.

This object is achieved with a shoe according to claim 1 (first aspect) and with a method for manufacturing a shoe according to claim 10 (second aspect). Preferred developments are the subject matter of the dependent claims.

The shoe according to the first aspect has a sock structure for receiving a foot and a sole mechanically connected to the sock structure. The sock structure has a liner and an insole that collectively define an interior cavity for a foot. The first edge section of the liner is joined to the second edge section of the footbed by means of a connecting seam. The upper leather is abutted against the outer surface of the lining layer. The strip-shaped portion of the vamp leather is folded over in such a way that it lies overlapping outside the interior space against the insole (pinch (zwickeinchlag)) and does not cover the free area of the insole arranged inside the second edge portion. The sole is frameless and is connected, in particular glued, to the band-shaped section.

The method of the second aspect is used for manufacturing a shoe, in particular for manufacturing a shoe of the first aspect. The method comprises the following steps:

s1, sewing the first edge section of the lining layer and the second edge section of the insole together to form a connecting seam and a sock-type structure with an inner cavity for receiving a foot,

s2 in particular after step S1 the vamp leather is applied against the external surface of the lining,

s3, in particular after step S2, the band-shaped section of the vamp leather is turned over in such a way that it lies overlapping outside the interior space against the insole and does not cover the free area (welt) of the insole arranged inside the second edge section,

s4, in particular after step S3, the frame-free sole is connected, in particular glued, to the band-shaped section.

Not only the shoe according to the invention but also the shoe manufactured according to the invention provides improved wearing comfort. In particular, in the design according to the invention, shoes worn mainly in cities and shoes that appear more traditional can provide a higher wearing comfort.

The free area of the sole, which is constructed without a frame, and of the insole, which is not covered by the band-shaped sections of the upper leather, can contribute to a lower bending resistance of the shoe being worn. The shoe according to the invention can be twisted relatively easily about its longitudinal axis from the heel toward the toe of the shoe. Shoes can resist natural rolling movements with less resistance. Furthermore, the free area can improve the output of moisture from the sock structure. Furthermore, the shoe according to the invention can be lighter than some known shoes. The object on which this is based is then solved. The extra insole (Einlegesohle) and separate cushion (fuβbett) for covering the connecting seam can be omitted. Furthermore, the joining of the seam and the band-shaped section of the vamp leather also makes it possible to improve the mechanical bond of the shoe over a longer period of use.

The term "free region" is understood in the sense of the present invention to mean a section of the insole which is arranged within the second edge section of the insole, which is surrounded by the second edge section and is not covered by the upper leather.

The term "strip-shaped section" is understood in the sense of the present invention to mean a section of upper leather which is defined and designed to be arranged or to be arranged between the insole and the sole without covering the free area.

The term "frameless" is understood in the sense of the invention to mean that the first section of the sole has a wall thickness which is not greater than the second section, which in the manufactured shoe encloses the second section of the sole which is or is to be connected to the band-shaped section.

The preferred embodiments explained below can advantageously be combined with one another as long as they are not explicitly excluded.

According to one embodiment, the connection seam extends along the circumferential outer edge of the insole or along a so-called "slat edge" in such a way that the sole arranged on the insole cannot reach or cover the connection seam. The wearing comfort can be improved by this arrangement of the connecting seams. Furthermore, the additional insole for covering the connection joint and the separate cushion layer can be omitted.

In one embodiment, the sole is connected, in particular glued, to the free region. This also improves the mechanical stability over a longer service period.

Another embodiment provides that the insole is constructed of a foamed material. The insole can be dimensioned such that it covers the heel (Ferse) and the forefoot (Fu beta ballen) or supports them when the shoe is worn. Shoes designed in this way can be better cushioned, especially when stepping onto hard floors.

According to a further embodiment, the second edge section is bent relative to the remaining insole and/or the free region, in particular in the direction of the sole. The contact between the foot and the connection seam can then be dealt with. Furthermore, the production of the connection seam can be simplified.

One embodiment has a backing layer constructed from leather and/or textile.

In a further embodiment, the connecting seam is formed along the circumferential outer edge of the insole, in particular as a blind seam. The contact between the foot and the connection seam can then be dealt with. In addition, the production of the connecting seam can be simplified or made more economical.

According to one embodiment, the upper leather, in particular the strip-shaped section of upper leather, covers the connection seam. Thus, moisture ingress into the shoe, especially during rain, can be reduced.

A further embodiment is characterized in that the upper leather is connected, sewn and/or glued to the outer surface portion of the lining layer in sections. This also improves the mechanical stability over a longer service period. In addition, undesired relative movements of the lining and the upper leather can be countered.

In one embodiment, the upper and/or the heel are placed on the upper leather. The upper and/or the heel can be sewn or glued to the upper leather. The shoe upper and/or the shoe heel have a band-shaped section which can be folded over in such a way that it extends in the direction of the free region without covering this free region. The band-shaped section of vamp leather can be arranged between the insole and the band-shaped section of vamp or heel. Thereby making it easier to manufacture the shoe.

According to a further embodiment, the wall thickness of the band-shaped section decreases in the direction of the free area of the insole. Thereby enabling improved wearing comfort. In addition, the weight of the shoe can be expressed lower.

One embodiment additionally has the following steps:

s5 roughens the band-shaped section and/or the sole, in particular before step S4.

When the sole is bonded to the roughened surface, a stable and more durable connection can be achieved.

Further embodiments further comprise the steps of:

s6, in particular after step S1, orients the sock structure by means of the slats previously arranged in the inner cavity.

With this step, wearing comfort can be improved. The lath can be removed from the cavity after step S4 (S9).

In a further embodiment, additionally:

s7, in particular before step S4, the upper and/or the heel is/are applied to the upper leather, and preferably

S8, in particular, the band-shaped section of the upper and/or the band-shaped section of the heel is turned over before step S4 in such a way that the respective band-shaped section does not cover the free region of the insole arranged within the second edge section.

During step S7, the upper and/or the heel can be stitched or glued to the upper leather. Step S8 can be carried out in such a way that the band-shaped section of the vamp leather is arranged between the insole and the band-shaped section of the vamp or heel. Between steps S8 and S4, the band-shaped section of the upper and/or of the heel can be roughened (S9). Thereby enabling the shoe to be manufactured more easily.
