Description

Liner and method of making the same

description

The invention relates to an inner boot for a ski, snowboard, inline skating

Shoe, mountaineering boots or the like according to the preamble of claim 1 and a method for producing an inner boot according to the preamble of claim 18,

Liner of the type mentioned here are known for example from DE 10 2007 002 335 A1, they are used for comfortable storage of a foot, wherein the liner in turn in a ski, snowboard, inline skating shoe or in a mountain boots or the like introduced can be. In such inner shoes, it is particularly important that a sufficient "condensation" - transport from the shoe inside to the shoe outside and at the same time a secure hold of the foot in the liner and a trouble-free boarding a carrier is ensured in the shoe.

It is therefore an object of the present invention to provide an improved innerboot which ensures both optimum fit and fit, and which moreover permits improved wicking of moisture away from the foot to the outside of the innerboot. To solve the above-mentioned object, an inner boot having the features of claim 1 is proposed. The inner shoe is used in particular for use in a ski, snowboard, inline skating shoe, mountain boots or the like and comprises a foam base material to which inner lining directly or indirectly (ie via one or more intermediate layers) in the inner region of the inner shoe applied is. The liner is characterized in that the inner lining of the liner is at least partially made of leather or a material with similar or the same physical properties. On a lining which consists of leather or of a material with similar or the same physical properties (ie a leather-like material or a imitation leather), in particular a hydrophobic sandwich material with membrane, hereinafter referred to as "leather lining" Leather is a material with special properties, it is not only very strong and durable, but also relatively impermeable to water, yet leather has good breathability, so it is sufficiently permeable to air and water vapor A material having the same or similar properties as leather is understood herein to mean a material having one or more of the same or similar properties of leather this Properties are in particular those which make an application for an inner shoe particularly advantageous. It is therefore preferably an imitation leather or an artificial leather, which has one or more positive properties of leather and this may even exceed.

The essence of the invention is therefore that the liner through the leather lining ensures optimum support and optimal fit, while additionally providing an optimal foot climate is given by a natural heat and moisture control. The leather lining provides an optimal grip for the foot due to its surface texture, which is slightly "sticky", thus preventing the foot from slipping in the liner, which also reduces the risk of blistering The foam base material provides optimal insulation and helps to regulate the leather's warmth.The combination of a foam base material and leather lining ensures an optimal foot climate and pleasantly warm and dry feet. Preferably, the foam base material is plastically deformable at least in a partial region at a predetermined temperature. In this way, a custom fit of the inner boot for individual wearers can be achieved. The foam base material can moreover have a perforation at least in a partial region. In this way, moisture created in the liner during wear of the liner may be more easily transported away from the foot through the perforated foam stock. The moisture gets in this way to the outside of the liner. The leather lining may advantageously have perforation, in particular a micro-perforation, at least in a partial region There is also achieved improved heat and moisture control and, in particular, improved wicking of moisture away from the foot to the outside of the liner.

Preferably, the leather inner lining is arranged in an entry region of the inner shoe. The entry area can simultaneously form a soft zone. This advantageous combination makes it easier to get into the shoe and also improves the wearing comfort of the liner. Also conceivable is an additional or alternative arrangement in a tongue region and / or in a forefoot region and / or in a shaft region. The leather inner lining can therefore be provided in at least two or more regions of the inner boot and extend over the aforementioned regions of the inner boot. Between at least two regions of the inner boot, in which a leather inner lining is provided, a material layer can be provided, by means of which the two leather inner lining regions are separated from one another. This material layer may in particular be the foam base material of the inner boot. In principle, however, it is also conceivable for leather inner linings to be contiguous and in particular integrally formed for a plurality of zones or regions of the inner liner.

Preferably, in the outer region of the inner shoe, at least in subregions, an outer lining is applied. This outer lining may preferably be on the

Foam base material may be applied. The outer lining may also be used improvement of the foot climate in the liner, at least in some areas have a perforation. Furthermore, the outer lining may be formed, at least in some areas, from a material promoting moisture transport from the inner area to the outer side of the inner boot. This may in particular be a material in which the moisture evaporates faster due to its surface on the outside of the liner. The outer lining may also consist, at least in some areas, of a material which is used in sports textiles, such as T-shirts or the like. In particular, it may be, for example, a hydrophobic material. Also particularly advantageous are materials in which the moisture is absorbed on the inside of the liner and is distributed over a large area on the outside, so that the drying process is carried out accelerated. Corresponding materials may also be arranged between the leather lining and the foam base material. It is also conceivable, alternatively or additionally, to provide a material layer between the foam base material and the outer lining which is formed from a material promoting moisture transport from the inner region to the outer side of the inner shoe. In principle, it is also conceivable to use a waterproof and breathable material layer, for example a membrane, which forms the outer lining or is arranged between the outer lining and the foam body. The inner shoe can be made waterproof in this way, while the breathability is guaranteed.

Advantageously, the foam base material is thicker in the entry area and in particular also in the tongue area of the inner boot than in the remaining areas or zones of the inner boot. The corresponding regions of the inner boot are in particular softened by the thicker foam base material layer, and consequently form a soft zone. This soft zone makes it easier to get into the shoe, especially in the entry area of the liner. The wearing comfort is thereby significantly improved. The same applies to the tongue area, provided that there is a thicker Schaumstoffgrundmaterialschicht than in the other areas of the liner.

If the inner shoe is provided with a closing mechanism, in particular with a lacing system and in particular also with a sole, it can also be provided that the inner shoe as a fully functional shoe for Use comes. The liner does not necessarily have to be used in a ski, snowboard or the like shoe to be used as intended.

To achieve the above object, a method for producing an inner boot having the features of claim 17 is also proposed. The method is used to produce an inner shoe, in particular for a ski, snowboard, inline skating shoe, mountain boots or the. Like., With a foam base material, The method is characterized by at least partially applying an at least partially made of leather or a material similar or identical physical properties existing inside lining inside the liner. Preferably, the inner lining is applied to the foam base material or one or more layers of material applied thereto, in particular sewn on.

Particularly advantageous is a method in which the foam base material is thermally deformed together with the applied lining of leather or imitation leather and thus optimally adapted to an individual support.

The invention will be explained in more detail below with reference to the drawing. Show it;

FIG. 1 shows a schematic side view of an inner boot according to the invention;

FIG. 2 shows a schematic side view of the inner boot according to the invention with marked leather inner lining areas according to the invention;

FIG. 3; a schematic rear view of the inner shoe with marked leather lining areas according to the invention, and

Figure 4; a cross-sectional view of the shaft portion of a

Liner with marked leather lining and outer lining areas. 1 shows an inner boot 1 with a foam base material 3. In the embodiment shown in FIG. 1, the inner boot 1 comprises a shaft region 5 and a tongue region 7, which pass over a forefoot region 9 or a heel region 11 into a sole region 13.

As the foam base material 3 is for example a foam of polyethylene (PE), polyurethane (PU) or ethylene vinyl acetate or foam rubber (EVA) into consideration. As indicated at the outset, these foams are preferably thermoformable, provided that an individual adaptation of the liner to a carrier is desired.

The inner shoe 1 is exemplified here with a lace cuff 15, which is detachably mounted on the liner 1 and which ensures by means of the lacing system 17, a fixation of the foot in the liner. It is understood that a fixation of the foot in the inner shoe can also be done by a lacing system, which is provided on an outer shoe, in particular on a ski, snowboard, inline skating shoe or the like. The liner 1 does not need to include an independent lacing system. In particular, when the inner shoe 1 is intended for self-service, i. without outer shoe, a corresponding lacing system, as shown by way of example in FIG. 1, can also be arranged directly on the inner shoe.

1 makes it clear that the inner boot 1 according to the invention has a collar-like access area 19. This area can be integrally connected to the rest of the inner shoe or be formed as a separate part, which is connected to the shaft portion 5 of the inner shoe 1, in particular sewn. The entry area 19 has a greater thickness than the other areas of the liner 1. The same applies preferably to the tongue area 7. In this way, not only a facilitated entry into the liner 1 is ensured in the entry area, but the resulting "soft zone" improves it In addition, the shoe much less so in the back of the calf.

FIG. 2 shows a schematic side view of the inner shoe 1 according to FIG. 1, whereby areas are schematically highlighted in which a leather inner lining 21 is arranged. It thus shows schematically an interior view of the liner 1. The areas hatched in FIG. 2 are, for example, the entry area 19, the heel area 11 and the forefoot area 9. The leather inner lining is applied in an inner area 23 of the inner boot 1 and thus on its inner side. The leather inner lining 21 is connected to the foam base material 3 and / or with an intermediate layer applied thereto in a suitable manner, in particular sewn or glued.

Several leather inner liners 21 on the inside of the foam base material are separated from each other by textile regions, wherein the textile regions are, in particular, the foam base material 3 or an intermediate layer applied thereto. The leather inner lining 21 is thus provided in the present embodiment only in sections in those areas of the liner 1, in which an improved grip and improved heat and moisture regulation is particularly useful and necessary. These are in particular the forefoot region 9 and the heel region 11. In another exemplary embodiment of the invention, it may also be provided that two or more leather inner lining regions 21 are associated for a plurality of zones 19, 5, 7, 9 or 11 of the inner liner 1 and consequently connected or integrally formed.

Both the foam base material 3 and the leather inner lining 21 may have a perforation, at least in some areas, whereby an improved moisture transport from the inner region 23 of the inner boot 1 to the outer side 25 is ensured. The open pores thus preferably extend from the inner region 23 or the inner side of the inner boot 1 to an outer side 25.

FIG. 3 shows a schematic rear view of an inner boot 1 according to the invention. FIG. 3 once again shows a schematic representation of the inner region 23 of the inner shoe 1 and illustrates the application of the leather inner lining 21 in the access region 19 and in the heel region 11. The leather inner lining 21 may extend at least partially over the shaft region 5. Between the two leather inner lining 21 in the entry area 19 and in the heel area 11 is a textile section in the form of foam base material 3 or at least one further material layer, which is connected to the foam base material. As shown schematically in FIG. 3, a perforation (shown dotted in the figure) of the leather inner lining 21 may be provided, for example, in the heel region in order to promote moisture removal from the foot to the outer side 25 of the inner shoe 1. The leather inner lining 21 in the entry area 19 can, but need not be perforated, since the climate in this area is basically better due to its proximity to the outside 25 than in the heel area 11 or in the forefoot area 9.

Fig. 3 also makes it clear that the foam base material portion between the two leather lining 21 in the entry area 19 and in the heel area 11 is also perforated formed, the perforation preferably also extends under the leather lining 21. Also, the foot climate by a optimal removal of "condensation" from the foot to the outside 25 of the liner 1 improves.

FIG. 4 shows a schematic cross-sectional view of the inner boot 1 according to FIG. 3. The hatched area, which marks the access area 19, makes it clear that this has a thickness d which is greater than the thickness in the remaining area of the inner boot 1. It will be appreciated that the thickness d need not necessarily be thicker than the remaining portions of the liner. The access area preferably forms a soft zone, which may consist in particular of the foam base material 3 or of another, softer material. A leather inner lining may also be provided in the region of the collar-shaped entry region (indicated in FIG. 4 by the reference numeral 21). The entry area 19 of the inner boot 1 may, as mentioned above, be formed as a separate part or in one piece with the foam base material 3. In the case of a separate embodiment, the access area 19 is connected to the foam base material 3 and in particular sewn thereto.

Moreover, FIG. 4 makes it clear that an outer lining 29 can also be provided on the outer side 25 of the inner shoe 1, at least in some areas. Also, the outer lining can be applied to the foam base material 3 or an intermediate layer applied thereto, in particular sewn or glued. Sport materials which can be used for example in T-shirts or similar sportswear are considered as materials. men. This may be, for example, a hydrophobic material. It is crucial that it is advantageously a material which promotes moisture transport from the inner region 23 of the inner boot 1 to the outer side 25. The material is preferably such that the moisture transported by the foam base material 3 is distributed over a large area on the outside and thus dries off more quickly. Incidentally, alternatively or additionally, further material layers may be provided between the inner lining, in particular between the leather inner lining 21 and the foam base material 3 or between the foam base material 3 and the outer lining 29, which may be perforated at least in some areas or other properties promoting the foot climate can have.

Overall, the present invention provides an advantageous inner boot, which ensures optimal support and a perfect fit and an improved foot climate through natural heat and moisture control using the leather lining. The optimized foot climate, which ensures pleasantly warm and dry feet, is achieved by the combination of the leather lining 21 and the foam base material 3. An improved moisture transport is achieved in particular if the leather lining and / or the foam base material 3 is open-pored at least in some areas and thus creates a transport path for moisture arising in the liner 1 on the outside 25.
