Description

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

Many shoes designed for a human foot have a sock that receives the foot and rests on an outsole. Shoes are often worn for many hours. The shoe should not unnecessarily restrict the rolling movement of the foot when walking. Furthermore, the foot gives off moisture, which the shoe should absorb and release into the environment.

The wearing comfort of some well-known shoes has been considered insufficient.

task and solution

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

This object is achieved with a shoe according to claim 1 (first aspect) and with a manufacturing method for 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 for receiving a foot and an outsole mechanically connected to the sock. The sock has a lining layer and an insole which together define an inner space for the foot. A first edge section of the lining layer is connected to a second edge section of the insole by means of a connecting seam. An vamp abuts an outer surface of the lining layer. A strip-shaped section of the upper leather is folded over in such a way that the strip-shaped section overlaps the insole outside of the interior (last fold) and does not cover a free area of the insole located within the second edge section. The outsole has no frame and is connected, in particular glued, to the strip-shaped section.

• S1 Vernähen eines erstens Randabschnitts einer Futterlage mit einem zweiten Randabschnitt einer Brandsohle, worauf eine Verbindungsnaht und eine Socke mit einem Innenraum zum Aufnehmen eines Fußes gebildet sind,
• S2 Anlegen eines Oberleders an eine Außenfläche der Futterlage, insbesondere nach Schritt S1,
• S3 Umschlagen eines streifenförmigen Abschnitts des Oberleders derart, dass er außerhalb des Innenraums an der Brandsohle überlappend anliegt und einen innerhalb des zweiten Randabschnitts angeordneten Freibereich der Brandsohle nicht überdeckt (Zwickeinschlag), insbesondere nach Schritt S2,
• S4 Verbinden, insbesondere Verkleben, einer rahmenlos ausgebildeten Laufsohle mit dem streifenförmigen Abschnitt, insbesondere nach Schritt S3.

The method of the second aspect serves to manufacture a shoe, in particular the shoe of the first aspect. The procedure has the steps:

• S1 sewing a first edge section of a lining layer to a second edge section of an insole, whereupon a connecting seam and a sock with an interior space for receiving a foot are formed,
• S2 applying an upper leather to an outer surface of the lining layer, in particular after step S1,
• S3 Folding over a strip-shaped section of the upper leather in such a way that it rests overlapping on the insole outside the interior and does not cover a free area of the insole located within the second edge section (last effect), in particular after step S2,
• S4 Connecting, in particular gluing, a frameless outsole to the strip-shaped section, in particular after step S3.

Both the shoe according to the invention and the shoe manufactured according to the invention offer improved wearing comfort. In particular, shoes that are mainly worn in the city and shoes that appear more classic can offer greater comfort when designed according to the invention.

The frameless outsole and the free area of the insole, which is not covered by the strip-shaped section of the upper leather, can contribute to a lower bending resistance of the shoe that is put on. The shoe according to the invention can be twisted more easily about its longitudinal axis from the heel to the toe of the shoe. The shoe can offer less resistance to the natural rolling movement. Furthermore, the free area can improve the removal of moisture from the sock. Furthermore, the shoe according to the invention can be lighter than some known shoes. This is how the underlying task is solved. There is no need for an additional insole to cover the connecting seam or a separate footbed. The connecting seam and the strip-shaped section of the upper leather can also improve the mechanical cohesion of the shoe over a longer period of use.

In the context of the invention, the term “free area” means 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.

In the context of the invention, the term “strip-shaped section” is to be understood as meaning a section of the upper leather which is defined and configured between the insole and the barrel to be or to be arranged on the sole without covering the free area.

In the context of the invention, the term “frameless” means that a first section of the outsole, which in the finished shoe borders a second section of the outsole that is or is connected to the strip-shaped section, has no greater wall thickness than the second section has.

Preferred Embodiments

Unless expressly excluded, the preferred embodiments explained below can advantageously be combined with one another.

According to one embodiment, the connecting seam extends along a peripheral outer edge of the insole or along the so-called "groin edge" in such a way that the connecting seam cannot be reached or covered by the sole of the foot arranged on the insole. The wearing comfort can be improved by this arrangement of the connecting seam. Furthermore, an additional insole to cover the connecting seam and a separate footbed can be dispensed with.

In one embodiment, the outsole is connected to the free area, in particular glued. As a result, the mechanical stability can also be improved over a longer period of use.

A further embodiment provides that the insole is made of a foamed material. The insole can be sized to cover the heel and ball of the foot or provide support when the shoe is worn. The shoe designed in this way can cushion better when stepping on hard ground in particular.

According to another embodiment, the second edge section is angled in relation to the rest of the insole and/or the free area, in particular in the direction of the outsole. In this way contact between the foot and the seam can be counteracted. In addition, the production of the connecting seam can be simplified.

One embodiment has a lining layer formed with leather and/or a textile.

In another embodiment, the connecting seam is formed along the peripheral outer edge of the insole, in particular as a blind seam. In this way contact between the foot and the seam can be counteracted. In addition, the production of the connecting seam can be simplified or more economical.

According to one embodiment, the upper leather, in particular the strip-shaped section of the upper leather, covers the connecting seam. This can reduce the ingress of moisture into the shoe, particularly when it rains.

A further embodiment is characterized in that the upper leather is partially connected, sewn and/or glued to the outer surface of the lining layer. As a result, the mechanical stability can also be improved over a longer period of use. Furthermore, an undesired relative movement of lining layer and upper leather can be counteracted.

In one embodiment, a vamp and/or heel rests on the vamp. The vamp and/or heel can be sewn or glued to the upper. The vamp and/or the heel has a strip-shaped portion that can be folded up so as to extend towards the free area without covering it. The strip-shaped section of the upper leather can be arranged between the insole and the strip-shaped section of the vamp or heel. This makes the shoe easier to manufacture.

According to another embodiment, the wall thickness of the strip-shaped section decreases in the direction of the free area of the insole. As a result, the wearing comfort can be improved. Furthermore, the weight of the shoe can be reduced.

• S5 Aufrauen des streifenförmigen Abschnitts und/oder der Laufsohle, insbesondere vor Schritt S4.

An embodiment additionally has the step:

• S5 Roughening of the strip-shaped section and/or the outsole, in particular before step S4.

If the outsole is glued to the roughened surface, a stable and more permanent connection can be achieved.

• S6 Richten der Socke mit Hilfe eines zuvor im Innenraum angeordneten Leistens, insbesondere nach Schritt Si.

Another embodiment also includes the step

• S6 straightening the sock using a last previously placed in the interior, in particular after step Si.

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

• S7 Anlegen eines Vorderblatts und/oder einer Ferse an das Oberleder, insbesondere vor Schritt S4,

und vorzugsweise

• S8 Umschlagen eines streifenförmigen Abschnitts des Vorderblatts und/oder eines streifenförmigen Abschnitts der Ferse derart, dass der jeweilige streifenförmige Abschnitt den innerhalb des zweiten Randabschnitts angeordneten Freibereich der Brandsohle nicht überdeckt, insbesondere vor Schritt S4.

In another embodiment, there is an additional

• S7 applying a vamp and/or a heel to the upper leather, in particular before step S4,

and preferably

• S8 Folding over a strip-shaped section of the vamp and/or a strip-shaped section of the heel in such a way that the respective strip-shaped section does not cover the free area of the insole located within the second edge section, in particular before step S4.

During step S7, the vamp and/or heel may be sewn or glued to the upper. Step S8 can be carried out in such a way that the strip-shaped section of the upper leather is arranged between the insole and the strip-shaped section of the vamp or heel. Between steps S8 and S4, the strip-shaped section of the vamp and/or the heel can be roughened (S9). This makes the shoe easier to manufacture.
