Description

Detailed Description of the Invention

The invention relates to a boot according to the preamble of claim 1, in particular a ski boot or a snowboard boot.
Boots, in particular ski boots and snowboard boots, have been known for a long time and conventionally consisted of an outer shoe and an inner shoe. While the user's feet are placed in and encased by the inner shoe, the inner shoe is often placed inside the outer shoe, which generally forms the stabilizing casing for the inner shoe, The outer shoe is completely enclosed.

  These boots have many disadvantages and, firstly, the significant weight of the inner / outer shoe structure. In addition, in order to tie both the inner shoe and the outer shoe individually with a string and take off the shoe, it is often necessary to unfasten the inner shoe and the outer shoe again. Furthermore, in the boot with the above structure, there is always a risk that moisture will collect between the inner shoe and the outer shoe, in order to dry, the inner shoe must be removed from the outer shoe, and Of course, a space for standing the inner shoe together with the outer shoe is necessary, so a considerable space is required.

  Therefore, in order to eliminate the above disadvantages, a one-piece boot structure in which only one shoe is provided and the shoe directly wraps around the user's foot has been used in the past. This one-piece boot construction has many advantages, such as a shorter sole, simplified handling of the boot, and in the case of ski boots or snowboard boots, the board feel is more directly felt Has been said regarding possible points. However, when comparing the above inner shoe / outer shoe structure with “normal” boots, the boots are especially soft around the “bends”, that is, in particular, the heel / ankle / shin part. There is a serious disadvantage of one-piece boots that it is highly mobile. This is associated with insufficient control of skis or snowboards.

  The object of the present invention is to solve the above problems while maintaining a one-piece boot structure and to provide a boot that is easy to handle and comfortably rides on the user's feet and shin / calf, especially with respect to skiing or snowboarding. In addition, providing a user with a certain holding force and adjustable rigidity provides optimum controllability.

This object is achieved by a boot according to claim 1, in particular a ski boot or a snowboard boot.
In particular, the object is a boot, in particular a ski boot or a snowboard boot, comprising a shell enveloping at least part of the user's foot and the user's lower leg, a shell tongue attached to the shell, and a sock-like liner having a tongue. The sock-like liner is disposed within the shell and extends over a portion of 20% to 80% of the shell height, preferably to approximately half of the shell height, while the tongue is This is achieved by boots, in particular ski boots or snowboard boots, which extend over a portion of 80% to 130% of the shell height, preferably to approximately 110% of the total shell height.

  An important aspect of the present invention is that the boot comprises a shell with a sock-like liner that does not reach the full height of the boot or shell, but extends only over a portion of 20% to 80%. The foot is substantially completely encased, in other words, at least around the ankle is encased by a sock-like liner, providing an optimal feeling of support within the boot, while the tongue attached to the sock-like liner is Or extend over the full height of the shell to optimize the user's forelimb with the lower part of the sheltang, the instep of the foot with the middle part of the sheltang, and the user's shin with the upper part Supporting and thus holding them in the boot according to the invention. As such, the user's foot, especially at the heel, which is particularly important to secure the user's foot stably in the boot, provides an optimal feeling of support while depending on the height of the sock-like liner The user's ankle and lower leg have high mobility, and at the same time, optimum comfort and fit. By using a tongue that extends beyond the sock-like liner towards the boot axis, the advantageous method according to the invention makes it possible for the “flexion” of the shoe to be relatively stiff, depending on the desired application. At the same time, it is certain that it can be comfortable. As a result, optimal controllability of skiing or snowboarding is ensured. According to a particularly preferred embodiment of the invention, the stiffness of the boot or its “bend” is adjustable by a shelter tongue, optionally with a reinforcing member and can be added, the shelter tongue being removable and replaceable It should be mentioned here that it can be attached to the shell.

  As such, by changing the shelter tongue, it is possible to change not only the rigidity or “flexibility” of the boot, but also the field of use of the boot. The reason is that boots can be optimized for regular skiing or snowboarding, for example by using stiffer tongues, while stiffer tongues require higher precision control, for example trick skiing This boot is suitable for adapting the boot according to the present invention to the field of use, and by replacing the hard tongue with a soft or very soft tongue, for example, even as a comfortable boot for walking, this boot is Because it is suitable.

  According to a further particularly preferred embodiment of the invention, the sock-like liner is fixedly connected to the shell, in particular adhesively bonded, so that there is no possibility of moisture permeating between the shell and the liner. Furthermore, the fixed connection according to the present invention of the sock-like liner and the shell ensures that the sock-like liner is always placed in the boot with a correct and accurate fit when the boot according to the present invention is attached or detached. Also, handling of shoes becomes easy.

  A further important aspect of the present invention is that at least a part of the tongue, i.e. a part having a height that exceeds the height of the sock-like liner, is movable independently of the sheltang, i.e. connected and glued to the sheltang. It is not joined. As such, according to the present embodiment, on the one hand, it is certain that the shelter tongue can be easily replaced. Furthermore, according to the present invention, the boots can be attached and detached more easily due to the independent mobility of the tongue and the sheltang. The reason is that the stiffer sheer tongue is in each case bendable considerably forward, while the soft and bendable tongue attached to the sock-like liner, for example by stitching or monolithic, is individually This is because it can move and adapt to the foot or shin.

  According to a further embodiment of the invention, the tongue has a larger height and width than the shell tongue, so that when viewed from the user's leg, the tongue completely covers the outer shell tongue and is comfortable to wear. It should be further pointed out to ensure comfort.

Furthermore, the sock-like liner has no seams, thus further improving the comfort of the boot according to the present invention.
Preferably, the sock-like liner further comprises a waterproof membrane, eg, a polytetrafluoroethylene (PTFE or Teflon) coating that is impermeable to water but permeable to vapor diffusion. According to the invention, as a result of the coating that can be used, the boot according to the invention can be configured to be waterproof.

Further embodiments of the invention will be apparent from the dependent claims.
In the following, the invention will be described on the basis of exemplary embodiments which will be described in detail with reference to the drawings.

1 shows a diagrammatic representation of a boot according to the invention. Figure 2 shows a separate view of the components of a boot according to the present invention.

In the following description, the same reference numerals are used for the same members and members having the same functions.
FIG. 1 shows a boot 10 according to the invention having a shell 20 into which a sock-like liner 1 is inserted. The sock-like liner extends over substantially half the height of the boot 10 or shell 20. Further, the sock-like liner 1 has a tongue 30 that extends beyond the height of the sock-like liner to approximately 110% of the height of the boot. The boot 10 of FIG. 1 is in a closed state, and it is clear that the shell tongue 2 is on the tongue 30, and the height dimension and width dimension of the tongue 30 are larger than the height dimension and width dimension of the shell tongue 2. Therefore, when the boot is in the closed state, the user's foot contacts only the tongue 30 and does not contact the shelter tongue 2. Therefore, even when the shelter tongue is stiff, good comfort is ensured.

  FIG. 2 shows the basic elements of a boot according to the invention in a separate view, the sock-like liner 1 having a tongue 30. In a state where the boot is completed, the sock-like liner 1 is adhesively bonded so as to be fixed to the shell 20. FIG. 2 further illustrates a shelter tongue according to the present invention that is removable and replaceable from the shell, as desired.

  Therefore, the core of the present invention can be summarized as follows. In the boot according to the present invention having a double tongue structure, a sock-like liner having an integral tongue is adhesively bonded to the shell. For this reason, the access opening is closed by the sock-like liner structure, and an inner tongue that substantially reaches one end of the shaft of the boot according to the present invention is formed. The tongue is substantially completely covered by the outer tongue fixed to the shell, that is, the above-described shell tongue.

As a result, the following three important advantages can be mentioned with respect to the boot structure according to the present invention.
1. Improved performance due to higher rigidity and various adjustable shelter tongue
2. Inner tongue / sock construction for better comfort and optimal fit, and
3. Feasibility of waterproof boot structure, waterproof form, sock-like liner, sock-like insert.

  Compared to a normal one-piece boot structure, the sock structure that wraps the foot and has no seam significantly improves comfort and fit. Furthermore, the inner tongue / sock structure completely covers the outer tongue. As a result of significantly improved comfort, the boot stiffness can be increased by the outer tongue. As a result, the performance of one-piece boot structures that are classified as very soft can be significantly improved. That is, according to this structure, the same performance as a normal boot structure, that is, an outer shell / inner shell boot structure, can be achieved by a one-piece boot structure. Further, the sock structure using the coating may make the boot waterproof.

It should be pointed out that all the elements mentioned above are recited in the claims as essential to the invention, as such and in any combination, in particular as shown in detail in the drawings. Modifications of the invention are well known to those skilled in the art.
