Description

Detailed Description of the Invention

The present invention comprises an outsole with an outer torso attached in a known manner to the upper part in a known manner so that the foot can be passed through, and said torso is provided by means of a closure device, such as a lacing. It relates to sports shoes of the type that can be closed above, in particular shoes for Wonder Vogel.

Of course, this torso ensures the shoe's seal against the external environment (especially rain or snow), but also mechanically protects the foot from falling rocks and other external hazards. In addition, ensure ankle retention and sprain protection, especially on sloping or uneven ground. For this purpose, some alpine shoes are even equipped with an outer torso made of a plastic material to withstand the special conditions for glacier climbing.

In order to ensure effective protection of the feet and heels, such shoes, especially with regard to the torso, are generally thicker and stiffer, such as leather or even plastic. Made of very strong material.

Therefore, in order to tighten the shoe on the foot by the conventional lace-up type device, it is necessary to strongly pull on the so-called torso region.

In view of the rigidity of the material, it is difficult to distribute the tightening stress. Therefore, the tightening is generally excessive, and as a result, a pain point, a pressure point, or the like that may cause serious damage during long-distance walking or repeated steps occurs.

In addition, inadequate tightening causes the foot to move inside the shoe, which causes friction between the foot and the shoe, which may result in "blister" or even burning bruises. Occurs.

In addition, when performing such a sport, the foot tends to slide forward inside the shoe when going down the slope, and as a result, the weight of the user moves to this part, so that the shoe tip It has also been confirmed that the tip of the foot is pressed and that local fatigue and unpleasant friction occur.

For example, French Patent No. 2651414,
German Patent No. 4032826 and French Patent No. 2
In some cross-country shoes such as those covered by 534459, a double torso (i.e., a partial inner torso that includes a lacing means for wrapping a portion and a cold, Protect the inner body lacing means against freezing and snow or water ingress)
It is known to provide an outer barrel or cover whose primary purpose is to

In such shoes, the constraints that have to be fulfilled are mainly the lightness and the softness in order to be able to spread the foot freely and completely and to obtain a minimum weight, and therefore these In these shoes, the problem underlying the present invention, which is to achieve both good mechanical protection of the foot (ie protection against impacts, falling stones, sprains, etc.) and easy and controlled foot tightening, is posed. No, and in such shoes, this problem cannot be solved a posteriori.

Similarly, DE-A-3436670 shows a sports shoe with an internal arch support means, which contributes entirely to the tightening of the foot in the shoe. is not. The reason for this is that external tightening means are additionally provided and do not give directions or solutions to the problems posed by the present invention.

The present invention has sufficient rigidity to ensure foot protection while at the same time providing controlled, simple and easy foot tightening within the shoe, while also providing effective foot protection. The purpose of the present invention is to eliminate these drawbacks by proposing a shoe for walking and hiking which can distribute stress for proper tightening.

To this end, according to the invention, the protective function of the foot, which is ensured by an external covering (in this case the outer torso), and the tightening of the foot, which is carried out independently of the torso by an internal tightening device, are provided. Separate from function.

According to another feature of the invention, the internal tightening device acts on the user's instep area at the same time and has two inner and outer sides which are fixed by one of their lower ends on the inside and the outside of the shoe, respectively. Composed of the tightening area of
The other upper free end is provided with its own coupling and tightening means arranged on the lower part of the outer barrel.

In this way, it can be easily understood that the protective function is further ensured by the outer barrel, so that the tightening stress can be distributed more easily. For the tightening area, one can consider more flexible materials that adapt to the shape of the foot.

The tightening zone is preferably arranged in the shoe so as to wrap around the instep between the flexion of the foot and the metatarsal joint axis.

Thus, speaking of the toes, these toes have some freedom of movement, which results in blood circulation, numbness in the feet, and unnecessary pressure on certain parts of the feet. Problems are reduced.

In fact, the following facts were confirmed: -Convulsions are more likely to be caused by excessive vertical pressure on the instep, and this vertical pressure causes the arch of Crushed (muscle fibers stretch). -Numbness or tingling may be due to an obstruction of blood or nerve circulation caused by excessive pressure on the forefoot or posterior ankle spaces on either side of the Achilles tendon.

Further, the degree of freedom of the front part of the foot rather than the instep part thus made makes it easy to carry the foot during walking.

It is advantageous to fabricate the tightening area with a perforated flexible cloth to make the shoe lighter and to provide easier foot tightening and ventilation.

The invention can be better understood by reading the following detailed description with reference to the accompanying schematic drawings, which show a preferred embodiment by way of non-limiting example,
Other features of the invention will also be apparent.

FIG. 1 shows a type of mountaineering shoe 1 including an outsole 2 with an outer torso 3 open at the front so that the foot 4 can pass through. Here, the body part 3 comprises two half covers, an inner half cover 3a located inside the foot 4 and another outer half cover 3b located outside the foot 4, and these two half covers 3a and 3b fasteners or They are connected to each other by a closure device 5, such as a self-adhesive means.

FIG. 2 shows these half covers 3a, 3 of the body 3.
Each of b is assembled by adhesion on the shoe sole 2 at the same time as the shoe insole 6 by adhesion in a joint area called "hanging allowance" 7 located between the shoe sole 2 and the shoe insole 6. It is indicated that.

According to the invention, this mountaineering shoe 1 acts on the foot 4 independently of the torso 3 for ensuring the mechanical protection of the foot 4, inside the shoe 1. It includes an internal tightening device 8 for ensuring protection of the foot 4.

This internal tightening device 8 acts simultaneously on the instep area of the user and is fixed inside and outside the shoe 1 via one of its lower ends 8c, 8d, respectively, and an inner tightening area 8a and an outer tightening area. It is constituted by two tightening areas in the area 8b. The other upper free ends 8e and 8f
When the body 3 is closed by its closing device 5,
A connecting and tightening means 9 is provided which is unique to them and which is arranged below the body 3.

By these two tightening areas 8a and 8b, the lower ends 8c and 8d of the tightening areas 8a and 8b and the half covers 3a and 3b of the body portion 3 are simultaneously interposed and adhered, and then the sole 2 is adhered. The user's foot can be pressed against a bottom pad (not shown) called a clean pad that is placed on the slinging insole 6.

Of course, the tightening areas 8a, 8b are not directly glued, but directly on the half covers 3a, 3b of the torso 3 by means of a seam (not shown) on top of the balance 7 of the torso 3. They may be joined via the lower ends 8c and 8d. In this case, the tightening areas 8a, 8b will be shorter.

As shown in FIGS. 1 and 3, the tightening area 8
The a and 8b are arranged at the instep portion between the bent fold portion 4a of the foot and the metatarsal joint shaft 4b.

The tightening areas 8a, 8b of the internal tightening device 8 are
It is preferably made of a flexible material such as a cloth having a hole having the above advantages or a mesh cloth.

Further, the connecting and tightening means of the upper free ends 8e and 8f of the tightening areas 8a and 8b are constituted by a string tightening device.

Alternatively, of course, a self-adhesive tape or any other suitable fastening means known per se may be used instead.
