Description

Detailed Description of the Invention

The present invention is directed to hiking shoes for hiking or wonder hogels, especially in medium or high mountains. This kind of shoe is
It is subject to heavy use in all terrains and mountains, and thus requires, above all, good foot retention and good foot and heel protection for the passage of stony ground, crumbling rocks and perennial snow.

Traditionally, this type of walking shoe is made of thick and reinforced leather to protect the feet and heels from crumbling rocks and rocks and to maintain good heel retention on undulating slopes. Including high torso. Due to the rigidity of the materials used, this walking shoe has only a slight longitudinal movement,
Therefore, it does not provide satisfactory comfort, especially at the flexion folds of the foot and at the Achilles tendon.

For example, according to European Patent No. 0030225, the production of mountaineering shoes also comprises a shoe shell made of a highly rigid plastic shell and including a plastic collar reinforcement member hinged to the shoe shell. Are known. Despite the more flexible leather part on the back of the boot, this type of hiking shoe is extremely rigid,
It does not allow the movement of the foot or the front-back movement of the foot with respect to the heel. In particular, the rigidity of the boot torso makes rotational movement of the collar reinforcement substantially impossible.

In ski shoes, it is also known to manufacture a shoe upper part in the form of a plastic shell lower part in which a plastic high part is hinge-connected. On the contrary, in this type of shoe, neither the movement of the foot relative to the ankle nor the mobility is considered, and the hinge connection of the high part depends on the body shape of the skier, and the high part of the shoe is lower than the shell. Its only purpose is to allow correct angle adjustment.

[0005] French patent application No. 8911936 proposed a walking shoe having a lower torso and a hard collar mounted on the upper end of the torso by a hinged connection.

Unfortunately, this type of shoe has problems with the seal between the lower torso and the hinged collar.

The object of the present invention is therefore to eliminate the abovementioned disadvantages and at the same time provide the comfort of the foot, its protection and its retention in the transverse direction, as well as the tightness, while also being sufficiently mobile in the longitudinal direction of the shoe. And to provide a walking shoe that imparts front-back flexibility.

[0008] For this purpose, the upper part of the shoe includes a lower part made of hard heel and upper, and a high part forming a collar integral with the lower part and made of a relatively flexible material. This is achieved in a mountaineering shoe according to the invention of the type which comprises a toe with a hard heel and a hard collar reinforcement hinged to the heel.

In fact, the high shoe upper can ensure the desired tightness, while the collar portion of the shoe upper is made of a relatively soft material, which allows the heel to flex with respect to the foot. Freedom can be sufficiently ensured and the mobility of the collar reinforcement is not impeded.

According to an advantageous embodiment, the tightening means of the shoe are arranged in each of the lower part of the boot and the collar reinforcement. In this way, the tightening area of the shoe at the location of the flexion of the foot is reduced and the risk of foot injury at this location is eliminated.

Further, means is provided for allowing the collar reinforcing member to move freely from the outside of the heel in the vertical direction with respect to the heel leather, whereby the heel is injured by the hard collar reinforcing member during walking. It is also advantageous to allow the harmonious carrying of the foot without the danger of.

In any event, the invention will be better understood by reading the following description, by way of non-limiting example, with reference to the accompanying schematic drawings which show some preferred embodiments, and Other features of the invention will be apparent.

As shown in FIG. 1, a shoe for hiking or climbing according to the present invention has the shape of a shoe having a high torso portion 1 and a sole 2. The torso of this shoe has a low part and a high part including a heel 3 made of a hard material and an upper 4 covering a front part of the foot as known under the trade name "PEBAX", for example. (That is, color) 5.

In the example shown, the upper 4 is made of thick leather and is thus made of a material that is relatively rigid, while the upper (or collar) 5 is, for example, of "CORDURA". As known by the product name,
Made from a fibrous material that is softer but tougher. Upper 4
The collar 5 and the collar 5 are connected to each other by the suture line 6 almost at the bent folds of the foot.

As shown in the figure, the rear part of the heel leather is provided with a notch 3A just above the heel so as not to prevent the backward bending of the foot or the heel. Therefore, the collar portion 5, which is made of a softer material, has a notch 3
It extends to the point a.

Moreover, the rear heel leather, as will be described later,
The collar reinforcing member 7 has a raised portion 3b serving as a hinge connecting portion on both sides of the foot. Like the heels, the collar 5 is a notch 5 to facilitate backward flexion of the heel.
a. The collar reinforcement member is, for example, "Pebax".
It is made of such a hard plastic material as described above, and is composed of a kind of sleeve which is hinge-connected to the raised portion 3b of the heel leather.

As shown, the heel leather extends on both sides of the shoe,
It is preferable to completely surround the heel. This heel leather is also 2
It may consist of a kind of U-shaped member whose branches extend vertically on both sides of the shoe and whose middle part does not surround the heel and extends under the inner sole (not shown) of the shoe. . In this case, the two branches of this reinforcement material constitute the raised portion 3a to which the collar reinforcement member is hingedly connected.

The hinge connection of the collar reinforcement member to the rear heel leather 3 can be carried out by any known method. In the example shown, this hinged connection is realized by means of a rivet 9 which penetrates the collar reinforcement 7 and is implanted in a boss which is connected to the heel leather. The collar reinforcement 7 and the collar 5, like the heel leather, are provided with notches 7a and 5a, respectively, in order to facilitate the flexion movement of the heel towards the rear and to avoid the risk of injury, especially at the Achilles tendon. Shoe torso 1
Both the high and low parts of the have separate lacing means 15 and 16, respectively. In fact, the lower lacing means 15 are arranged only on the upper 4 of the upper, whereas the upper lacing means 16 are movable independently of the collar. It is provided only on the reinforcing member 7. As shown in FIG. 2, the lacing means 15 comprises an annulus 17 and a self-closing hook 18 which is arranged at the connection between the high and low parts and thus approximately at the bend of the fold. .

The lacing means 16 in the high portion is composed only of a hook arranged in the front portion of the collar reinforcing member 7. In the illustrated example, the same shoelace 19 simultaneously passes through the ring 17 and the hook 18 of the lacing means 15 and the hook 19 of the lacing means 16, but these two shoelaces are separated from each other by two systems of lacing means. May be provided for. Therefore, lower lacing means 15 and 19 for tightening the shoe on the foot, and higher lacing means 16 and 19 for tightening the collar reinforcement around the ankle.
2 completely separate lacing means are obtained.

Since the so-called high-lacing means of the upper part of the shoe upper is arranged on the movable collar reinforcing member 7 irrespective of the upper part of the shoe, the "fastening" means is not provided at all. It should be pointed out that this is not the case and this makes the ankle flexible. Further, the lacing means of the collar reinforcing member 7 is disposed at a high portion of the collar reinforcing member, so that only the high portion of the ankle is tightened, and there is no tightening means at the position of the bent fold of the foot. Also point out. As a result, the wearing comfort of the user is increased and especially the areas of tightening and compression are eliminated. Therefore, the user feels more freely movable with respect to the foot, thanks to the hard collar reinforcement 7, especially while the ankle is very well held laterally.

It should be further pointed out that instead of the high-lacing means 16, other suitable fastening means can be used, for example a "VELCRO" type fastening means.

FIGS. 3 and 4 show a mountaineering shoe according to another embodiment, in which similar parts are designated by the same reference numerals with the addition of 100. Therefore, this mountain walking shoe is composed of the high torso portion 101 and the shoe sole 102, like the shoe of FIGS. 1 and 2.

Like the shoes described above, this shoe is made of hard heel leather 10.
3, on which a collar reinforcement 107, which is also made of a hard material, is hinged. The shoe also has a high torso portion (i.e., collar 105) made of a flexible fibrous material, such as is known under the trade name "CORDURA". The essential difference between the shoes shown in FIGS. 3 and 4 is that the inner tightening device 110 is provided.

As shown in more detail in FIG. 4, this medial tightening device 110 comprises two tightening zones 110a extending at the ankle and provided with lacing means 110b. This inner tightening device 110 is equivalent to the lower shoelacing means 15 of the shoe described above, and therefore
Similarly, it extends almost to the flexion fold of the foot.

In this embodiment, the uppers are two parts 10 which are connected to each other by a fastener type opening / closing device 104c.
4a and 104b, this assembly covers the inner tightening device 110. Further, the upper end of the upper part 104b is provided with a self-adhesive hooking means 104d which is closed on the collar 105 in order to ensure the tightness of the shoe. In this case, instead of the lacing means 16 in the high part of the shoe, the hooking means 11 is hooked on the ring 118 and is held.
9. A clamping means 116 of the type constituted by a band-shaped member 117 which can be clamped with a desired tension at 9 is used. This type of tightening device
Prior French patent application No. 910755 in the name of the applicant
No. 5 specification. Of course, instead of this tightening device 116 it would be possible to use other suitable tightening means, for example self-cohering means.

In this second embodiment, the fastening means 110b of the lower part 103, 104 of the shoe and the collar reinforcement 1
The fastening means 116 of 07 are likewise completely separated. As in the previous example, since the collar 105 of the shoe is made of a flexible fiber material, the degree of freedom of movement of the ankle with respect to the foot can be increased, and good protection of the ankle (particularly in the transverse direction by the collar reinforcing member 107) can be achieved. Good protection) can be guaranteed.

Furthermore, in order to help the comfort of use of a shoe of this kind, this shoe in each of the embodiments shown in FIGS. 1 to 4 has a collar reinforcing member 7 for the heel leather 3, 103. It has the freedom of vertical movement of 107. This kind of freedom of movement is obtained by the vertical slits 20, 120 on which the shafts 9a, 109a of the hinge connecting studs of the collar reinforcing members 7, 107 on the heel leather 3, 103 slide. This slit is provided on the collar reinforcement 7, 107 on the outside of the shoe and makes it possible to lower this collar reinforcement against the heel leather during walking.

In fact, the movement of the foot is generally accompanied by a slight inclination of the ankle towards the outside, and the freedom of movement of the collar reinforcement thus made possible on the outside of the shoe allows this movement during the movement of the foot. The collar reinforcement can be lowered slightly, thus improving comfort and eliminating the risk of ankle injury due to the upper end of the collar reinforcement 7,107.

It should be noted that in the embodiment shown in FIGS. 3 and 4, the torso 104 includes a short tongue 104c that does not extend beyond the flexion folds of the ankle, which means that the upper portion of the collar 105 is It should be pointed out that this is made possible by the upper portion 104b of the upper that extends up to and closes the front of the upper at this point. This gives greater freedom of movement.

In the example of FIGS. 1 and 2, the tongue 4c extends and is maintained above the collar 5 of the upper to ensure the tightness of the assembly on the front. .
