Abstract

Locally, on the exterior of the substrate (2), supportive material (5) is attached; this is area-bonded to the substrate, preferably over the entire area of contact. An Independent claim is also included for the method of making the inner shoe. The thermoformable foam substrate is shaped for a foot and is laid into a mold, which is closed. Supportive material introduced, is located for external bonding onto the substrate. The product is hardened, the mold opened and the inner shoe is extracted.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The invention relates to an inner shoe for sports shoes, preferably of a foamed, heat-deformable material and provided with a carrier that can conform to the shape of the foot, in particular for snowboard boots or ski boots. .

[0002]

[Prior art]

 It is well known that ski boots and snowboard boots in particular use an outer hard shell and preferably a removable inner shoe. There is already an inner shoe made of thermally deformable material (eg EVA / PE) with fabric on both sides. The foamed material can conform to the shape of the wearer's foot when warmed, which makes it more comfortable to wear. In addition, such materials are comfortable and warm. A disadvantage of such materials is their relatively poor durability.

[0003]

[Means for Solving the Problems]

 According to the invention, a reinforcing material is applied to a part of the outside of the carrier, wherein the reinforcing material is joined to the carrier in a planar manner, preferably in an entire plane. Reinforcement points are located at appropriate points for durability, especially at the back or front of the shoe upper and also on the tongue, depending on the position, size and thickness of the apriquet of reinforcement material. It is possible to precisely match the strength characteristics required for inner shoes. Furthermore, it is possible, for example, to form soles from this more stable reinforcing material. According to this invention, this material is not applied to the entire outer surface of the inner shoe, but is applied only in the desired area and the carrier is exposed elsewhere.

[0004] Equally important in this invention is that the reinforcing material is planarly joined to the carrier. The reinforcing material is therefore not joined to the carrier material only at several points or only along the seams. Rather, they are joined over a large plane, so that the carrier material and the reinforcing material are statically integrated, so that a better reinforcing effect is obtained. The reinforcing material is joined planarly, especially at its peripheral edge. Naturally, all-plane joining in which the entire plane of the reinforcing material is joined to the carrier material is preferred. As a result, an excellent reinforcing effect is obtained, and in particular, there is no danger of the reinforcing portion coming off the carrier.

[Embodiment of the invention]

 Further advantages and details of the invention are explained below with reference to the drawings.

The inner shoe 1 for a snowboard boot shown in FIG. 1 is made of a heat-deformable material, preferably ethylene / vinyl acetate copolymer (EVA) and / or polyethylene (PE). It has a carrier 2 adaptable to its shape. On this carrier, an inner lining 3 made of a textile fabric, for example polyester, is applied. On the outside is also provided a planar formation of fibers, in particular in the form of a woven fabric of PUR stretchable fibers or polyester. The fibrous plane formed product is closely bonded to the shaping layer 2a (EVA / PE) of the carrier 2. Therefore, the carrier 2 in the embodiment shown in FIGS. 1A and 1B is composed of three layers, that is, the layers 3, 2a and 4.

In order to improve the durability of the shoe and obtain a more stable shoe sole, in the embodiment according to the invention shown in FIGS. The reinforcing material 5 is applied to the area, and the reinforcing material is bonded to the carrier 2, that is, the fiber woven layer 4 of the carrier 2 and the entire plane thereof. The textile layer 4 allows a good and close retention of the reinforcing material 5 on the carrier 2.

[0008] The reinforcing material is preferably made of polyurethane which can be foamed or poured and the application inside the closed mold is preferably by injection molding or foaming, whereby the shape of the reinforcing material 5 in contact with the carrier is improved. Can be defined, and a good bond of the materials can be guaranteed. However, it is also basically possible to apply or weld the reinforcing material 5 in a planar manner.

As is evident from FIG. 1 (a), the reinforcing material is arranged in the area of the sole of the inner shoe, the back of the shoe upper and the tongue 6. It is clear that the reinforcing material covers the carrier 2 only in a limited area, i.e. only where it is to be reinforced. Further, from FIG. 1 (b), it can be seen that the thickness of the reinforcing material changes and preferably becomes thinner toward the edge. This makes it possible to precisely match the required stability characteristics to various requirements. The thickness of the reinforcing material is at least greater than 2 mm for each region, and preferably greater than 5 mm for obtaining an excellent reinforcing effect. Furthermore, the reinforcement material may have a lace hole 7 for a lace 8.

The embodiment shown in FIGS. 2 (a) and 2 (b) basically differs only in the arrangement of the reinforcing material 5 in the carrier 2. In particular, reinforcement material is stretched over the entire heel region 9 and extends further up in the sole region. Further, the embodiment shown in FIGS. 2 (a) and (b) is not tied. Otherwise, the same reference numbers indicate the same parts as in FIGS. 1 (a) and (b).

The same applies to FIGS. 3A and 3B. Again, the same reference numerals as in the above figures indicate the same or corresponding parts. Also in these embodiments, the difference is the position and arrangement of the reinforcing material 5 on the carrier 2. Further, in FIGS. 3 (b) and 4 (b), the reinforcing material 5 is applied directly on the modeling material 2a (without a fabric layer between them).

FIG. 5 shows an embodiment of an apparatus for performing a preferred process according to the present invention. A carrier, provided with a removable core 10 and having the reference number 2, which basically corresponds to the shape of the wearer's foot, is inserted into a mold consisting of two halves 11a and 11b. The mold is then closed so that the separation seams 12 fit tightly. FIG. 5 shows this closed state. This mold has a supply channel 13 for the reinforcing material. This supply channel 13 leads to a mold cavity 14, which cavity corresponds to the shape of the reinforcing material to be applied.

Then, the mold is opened and the inner shoe is taken out. When the core 10 is removed, the inner shoe is completed.
