[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to footwear having a sole consisting of at least two layers.

0002

BACKGROUND OF THE INVENTION As is well known, some footwear such as slippers or sandals have a rigid sole, in particular a wooden sole, and in the case of so-called health sandals, clogs or running shoes, for example EP-A2 -41201,
EP-A3-80456, EP-A1-98964, G
As disclosed in B-A-221064, GB-A-2001845 or GB-A-2111822, such soles have a surface in contact with the user's foot that conforms to one of the common foot anatomy. Some even have a midsole.

[0003]Modern ski boots also usually have a rigid sole, but such shoes also use an insole - in some cases adapted to the foot of the individual user. It is difficult to walk, let alone run, in such shoes. On the other hand, as is well known, a rigid sole supports the body stably, so it does not consume much energy when standing, and has the advantage of reducing tension throughout the body, especially the muscles of the lower legs, especially the shins. Also, since there is no friction between the foot and the shoe when walking, muscle tension and blister formation can be avoided. Moreover, even after long-term use, the upper leather of the shoe hardly has any horizontal wrinkles, so the appearance of the shoe can be maintained in good condition for a long time.

0004

SUMMARY OF THE INVENTION It is an object of the present invention to combine this known advantage of a rigid sole with an anatomically shaped elastic midsole in a way that is easy to manufacture and easy to wear for the user. To provide footwear that makes one feel comfortable and relaxed when standing, walking, or running.

[0005]

[Means for Solving the Problems] This object has a bottom part 14 consisting of at least two layers, and an upper surface 16 of the midsole that contacts the user's foot on the inside (upper side) has an anatomical shape. It is formed in an elastic midsole 4 and is provided with at least one rigid core 10 on its underside, with said sole 14
has a tread portion 23 that is curved upward by a height of Hz at its front end (range of toes), and its tip is 10 to 10 degrees from the ground contact surface 12.
50mm, preferably adult shoe size 30-4
This can be achieved by footwear having a sole consisting of at least two layers formed 0 mm apart. Moreover, in this case, the user does not have to give up supple stepping and light foot movement when walking. Further embodiments and refinements of the invention are found in the features of the dependent claims.

[0006]

SUMMARY OF THE INVENTION A "rigid" layer or core within the meaning of the present invention is a core that substantially prevents bending in the area of the ball of the foot. For example, place it on fulcrums spaced 25cm apart and
The core is said to be sufficiently rigid if the deflection when a load of kg is applied is 10 mm or less, preferably less than 5 mm.

Basically, it is possible to simultaneously use this rigid core as the outsole (outsole) of the bottom of the footwear of the present invention, but it is possible to use an elastic, particularly wear-resistant material on the underside of this rigid core. It is preferable to provide an outsole consisting of, which may also be patterned to improve the grip and anti-slip effect. If you remove the rigidity in the toe area, the toes will work together during movement, so the ball area - there will be no bending! - Following this, you can lower your foot slightly. Instead of omitting the rigid core, the rigid core may be separated between the toe area and the ball area or may be provided with a groove to allow bending.

[0008] Removing the rigid core is EP-A2-4120
1, but in that case, the rigid center is already eliminated in the area of the ball of the foot, so when walking or running, it bends to the area of the ball of the foot, just like in conventional shoes, so the center of rigidity is eliminated. No healthy effects can be obtained. Also, this outsole has a protrusion, but the protrusion is located below the instep area, not the ball of the foot, so it may cause damage to the sensitive fornix of the midfoot when walking. It will be compressed through the rigid heart.

As is known per se, raising the stiffness core in the heel area improves the supporting effect of the foot, in particular in the midfoot and heel area, in particular in conjunction with other features of the invention. do. A slight difference between a general foot shape and an individual's foot shape can be smoothed out by making the insole easy to deform. In order to compensate for this lifting of the heel portion of the rigid core, the rigid core can be made thicker toward the rear. However, it is preferable to compensate for this height difference with an outsole or to insert a wedge - preferably at least semi-elastic - under the rigid core or between the rigid core and the outsole, if any.

In principle, it is also possible to anatomically shape the upper surface of the rigid core - in a manner known per se - but this involves high production costs and it is also possible to shape this surface to an individual foot shape. This is not desirable because it cannot be adjusted to Just as fingerprints differ from person to person, the dimensions of the bulge and depression on the sole of the foot vary greatly, so an insole that is tailored to the general anatomy of the foot may be extremely inappropriate for some people. In other words, if you wear conventional insoles for a long time, you may develop calluses that cause damage, making the shoes ``unhealthy shoes.'' However, trying to match the rigid shoe sole to the shape of the upper surface of the midsole required by each user results in increased tool costs and processing costs.

[0011] If the insole is made of an elastic material, on the one hand it will be more comfortable for the user to wear, and on the other hand it will be easier to manufacture. However, this need not eliminate the advantage of a rigid core. By combining both, you can obtain the stable movement of your feet that you need when walking. The insole can also be manufactured individually for each user using methods known per se. For this purpose, plantar impressions, molds, computer records, etc. were used. The midsole thus produced is placed or preferably glued onto a rigid core or midsole, if present in the shoe. Alternatively, it is also possible to create a personalized insole directly using a moldable material that attaches to the user's foot.
- If necessary, wrap it in a film, etc. - Apply it and let it harden in that state. In this way, the user can immediately purchase his/her own shoes with an insole tailored to his or her feet at the shoe store.

[0012] The insole can be constructed in two or multiple layers - in order to be better adapted to the individual user. On the one hand - on the basis of an elastic midsole shaped according to the general anatomy - additional cores above or below the general midsole may be used to perform individual fittings. . This additional core may be the same thickness over its entire surface, or may be thinner towards the toe. Alternatively, by combining two or multiple layers of elastic cores preformed in different shapes, it is possible to obtain an insole that closely, if not perfectly, fits each individual's foot. Moreover, by removing such an additional part of the mind, it is possible to even out the difference between the same user's relaxed ``morning feet'' and the thickened feet after long periods of standing or walking. be.

[0013] The insole as a whole, or at least only on its upper side, can be designed in such a way that it absorbs moisture, especially in the area of the ball of the foot and/or in the area of the heel. The simplest way to do this is to provide perforations or small protrusions on the upper surface of the insole, in some cases only partially, but in some cases perforations may also be provided in moisture-absorbing materials such as the inner sole of shoes. It is even better to provide and coat this surface with it and/or to embed activated carbon or the like in the insole and/or the coating.

[0014] If an upwardly curved stepping part (heel curve) is provided in the heel area at the rear end of the shoe or sandal of the present invention, the movement when the foot is lowered is soft and the sudden impact is avoided. It has the effect of not being affected by If the rigid core in the area of the toes is removed, the missing area can be filled with another suitable, preferably elastic, material. Alternatively, the outsole, wedge core and/or midsole may be formed to fill this location. This lack allows the toes to move freely;
The toe of the shoe (but only the toe of the shoe!) bends, allowing the foot to bounce elastically when walking. This simulates an ability that has already been lost to civilized humans: the ability to use the toes, which are dug into the soft forest soil by the weight of the entire body at the end of a walking step, to take the next step. It can also be said that it is working. This is especially effective when running, and with the shoes of the present invention, you can run faster than with conventional shoes by taking a strong step.

In order to facilitate the shaping of at least one of the curved treads at both the toe and the heel, the corresponding front or rear ends of the outsole, rigid core and/or wedge core, respectively, are shaped. Can be made thinner. Providing diagonal grooves or cuts in the outsole that open toward the ground surface is effective in providing elasticity or a cushioning effect that reduces the burden on the joints when the foot is put down. It is better to cut off the sharp corners of the bottom pattern (as viewed in vertical section) so that these cuts do not become clogged with stones and spoil the effect. preferable.

In the footwear concept of the present invention, the top of the user's foot is affected somewhat differently or more strongly than in conventional shoes. That is, when walking, the foot (which bends only in the area of the ball of the foot) pulls on the shoe. Important muscles and blood vessels are concentrated on the top of the foot, and pressure is applied to them. In particular, the extensor Hallu muscle running along the line EHL in Figure 5b
In order to reduce the burden on the cisLongis, the lace stopper is arranged outwardly from the central axis of the instep, and at least the uppermost lace hole is made to protrude outward from the instep part of the shoe. The features were demonstrated to be effective.

Here, FIG. 1 is a longitudinal sectional view of a slip-on shoe having a sole according to the present invention, FIG. 2 is a longitudinal sectional view of an example of a rigid core with an outsole, FIG. 3 is a partially cutaway perspective view of the midsole, and FIG. 4a , b is a plan view of two embodiments of the insole, FIG. 5a is a shoe with laces of the present invention, the left half is a side view and the right half is a longitudinal sectional view, FIG. 5b is a plan view of the same shoe, and FIG. 5c is a top view of the same shoe. A side view of this shoe when a load is applied, FIG. 5d is an enlarged view of section D in FIG. 5a, FIG. 6 is a conceptual side view of the tip of the shoe in FIG. 1, and FIG. 7 is a side view of a sandal having the sole of the present invention. 8 is a side view of another embodiment of a shoe with laces having a sole according to the present invention,
FIG. 9 is a side view (a) of another embodiment of the sandal of the present invention and an exploded longitudinal sectional view of its sole (b), and FIG. 10 is a toe and finger of another embodiment of the outsole of the present invention. FIG. 3 is a longitudinal cross-sectional view of the sphere area;

The slip-on shown in FIG. 1 has a multi-layered sole 14 consisting of an outsole 11, a rigid midsole 10, and an insole 4. The inner rigid core 10 is made of a rigid material such as wood or hard synthetic resin, while the midsole 4 and the outsole 11 are made of elastic materials, possibly of different compositions. Wood as a natural material is suitable for the rigid core 10, in particular a plywood panel. This rigid core 10 has substantially the same thickness over its entire length, which is preferably less than 1 cm, in particular 0.5 cm, for example in the case of hard fibreboard or particleboard.

By embedding internal screws, nuts, etc. in the rigid core, it is especially possible to attach, fix, and fix nail-like spikes (for example, for running shoes and golf shoes) or small protrusion-like spikes (for example, for running shoes and soccer shoes). It becomes possible to easily perform removal. Especially when it comes to golf shoes.
This rigid core improves the stability of the body when holding the stance, which is extremely important for making an accurate swing.

Furthermore, a steel plate or a glass fiber reinforced plastic plate can also be used as the rigid core, the thickness of which is generally less than 2 mm, and in some cases even less than 1 mm. This core supports your feet when you are standing, thereby reducing the strain on your gastrocnemius muscles. The rigid core 10 extends from the heel range f to the ball of the foot range b, but it is more comfortable to walk without the toe range, which allows the toes to bend and allows free movement. , it has the effect of letting your feet bounce when you walk.

The rigid core 10, which itself consists of a flat or plate-like material, is provided with some camber in accordance with the general anatomy of the foot. but preferably of a flat shape, in longitudinal section only, in the area of the heel - preferably about 15 m
m by a height h - raised to provide better support for the midsole 4. In this manner, the rigid core 10 has a shape approximately similar to that found in conventional shoes. On the other hand, on the inside of the sole 14, and therefore on the inside of the midsole 4, there is formed an upper midsole surface 16 that is individually tailored to the actual foot shape of each user. Differences between the general shape and the individual shape of the rigid core 10 are smoothed out by this elastic, deformable midsole.

[0022] The bottom surface 17 of the outsole 11 has a range b of the ball of the foot.
For example, a log-shaped protrusion 17 is formed on the underside of the shoe over the width of the sole.
A is preferably provided, which facilitates healthy walking or running by shifting the body weight, and also reduces energy consumption. Many people's complaints lie in the toes. rigid core 1
0 and the "log" 17a according to the present invention, it is possible to eliminate the bending of the back.

Furthermore, FIG. 1 shows a protrusion 6 provided in the heel area f of the outsole 11. Similarly, this protrusion can be provided vertically in the running direction in a log shape, and it is effective to combine it with the heel curvature Hf. This protrusion first touches the ground surface 12 each time the person walks, and at the same time provides the correct direction of walking. From FIG. 2 several variations of the rigid core 10 of the invention with an outsole can be seen. The rigid core 10 in this figure is not cut out in the area z of the toe, but is bent by the groove 22. Further, the outsole 11 is thick in the ball area 11b of the foot, and gradually becomes thinner toward the tip from there so as to contribute to the warpage Hz. Finally, the outsole 11 in FIG.
, which may be made into a log shape. This has the effect of orthopedically correct lowering of the foot when running, and also protects the lower back joints. This protruding part is connected to the lip-like part 26.
It is also effective to further expand the size. In some cases, this lip-like part 26 - even the inside of the heel - is made of a relatively soft synthetic resin with elasticity, and the original outer sole of the heel 11f is made of a hard, wear-resistant material with elasticity. You can also do it like this. Instead of cutting diagonally like this with or without the lip 26, cut the heel area 1 of the outsole.
The same effect can be obtained even if the rear end of 1f is made of a soft material having elasticity.

The insole 4 (FIG. 3) has a shape obtained using known techniques, for example by molding a model, which closely resembles an orthopedically adapted insole. There is. This midsole has the above-mentioned toe range 4z with a recess for storing the toe, a toe ball range 4b with a recess for storing the ball of the foot, and a fornix on the underside of the instep. ) and a heel area 4f with a depression that supports the heel.

As shown in FIG. 4a, the midsole 4 or its upper surface 1
The sole leather placed on the top surface 16 of the bottom
Providing perforations 24 in the area of the feet, and in some cases even in the midfoot area, improves air circulation to this area that supports the particularly sensitive soles of the feet, thereby facilitating the evaporation of sweat from the feet. It has the effect of The same effect can be obtained by providing a large number of small protrusions instead of the perforations inside the midsole 4.

In order to correspondingly support the preferred configuration of the rigid core 10 according to FIG. 2, it is advantageous to use a patterned sole 11 as an outsole. It is effective to form this outsole 11 so as to support the lifting of the heel region of the rigid core 10, that is, so that the heel region f is higher than the ball region b. This height difference h is usually 5 to 25 mm,
In particular, it is in the range of 10 to 15 mm. If it is about 15 mm, most of the adult's legs can be supported in a way that best reduces the burden on the gastrocnemius muscles.

According to the invention, it is also possible to tailor the wear-resistant outsole 11 to individual dimensions using easily moldable materials or to form the individual areas with different hardness. For example, the elasticity of the heel area of the outsole 11 may be made somewhat greater, the instep and toe area may be made somewhat harder, and the ball area of the foot may be made semi-elastic. Also, the outer sole 11 is the range of toes 1
1z to the inside and make the upper surface line up with the upper surface of the rigid center 10 that has been removed here, the rigid center 1
It can fill in the missing 0's. This thicker part becomes thinner toward the tip of the foot, contributing to the formation of a curved foot (Hz).

The upper 15 shown in FIG. 1 has a slip-on
Since these are shoes, there are no holes for laces. The upper can be attached to the sole in a variety of conventional ways. For example, the lower end of the upper is folded under the circumference of the rigid core 10, tightly sandwiched from below, and glued or sewn together, or the lower end of the upper is folded outward and glued or sewn from above to the slightly larger rigid core 10. . Furthermore, if the upper 15 is in particular a fabric, it is glued to the rigid midsole 110 and the insole 4 is then secured - preferably also by gluing.
A method of inserting it into a shoe is also possible. Alternatively, a midsole 13 (FIG. 5a) may be inserted between the midsole 4 and the rigid core 10.

Since the sole 14 hardly bends, wrinkles do not form on the instep when walking or running, and there is no pressure on the instep of the foot, making it possible to reduce or avoid tension in the foot. It is also advantageous to make use of injection molding and, in some cases, co-foam molding, as is known with polyurethane, for the manufacture of the sole of the footwear of the invention. In some cases it is also possible in this way to attach both the insole and the outsole on both sides of the rigid core in one step, in which case the rigid core is provided with holes 7 for fixing or passing through the corresponding material (Fig. 4b). It is preferable to provide

Depending on the material used for the rigid core, it may be possible to provide a more or less large or small hole only in the area of the heel to reduce the weight. In this case, either the entire sole is made of a single elastic material and the parts where the rigid core is to be hardened are used, or the sole is made of a single hard material and the elastic midsole is made soft, for example by foaming. It would also be possible to do so.

In the shoe with laces 9b of FIG. 5b, all the features of the shoe according to the invention explained with reference to FIG. 1 can be recognized. Furthermore, there is another center 13, which firmly connects the upper part 15a and the sole part 14 of the shoe. In addition, the wedge core 19 made of an elastic material compensates for at least a portion of the heel region lift h (FIGS. 1 and 2) of the rigid core 10, and at the same time provides cushioning in the heel region f when walking. Increase effectiveness. String stop 20 is extensor Halluc
is Longis EHL is offset outward from the center line M of the instep so as not to put strain on the EHL, and the upper lace hole 21 is located in the instep part 15 as clearly shown in Figure 5b.
It protrudes from the top, which eliminates pressure on the top of the foot. Finally, the outsole 11 is provided with a notch 25 that opens diagonally towards the ground plane 12 - preferably towards the rear - and which closes under load to increase the damping effect, as shown in Figure 5c. The notches 25 may be provided in various ranges of the outsole 11 with different inclinations. As can be seen in the longitudinal section, the protrusion 27 produced by this cut has a sharp corner 2, which is preferably cut off vertically, as shown in FIG. 5d.

The toe of the slip-on shoe shown in FIG. 6 has a front end 23 of the sole that is greatly curved upward (compared to the position 23' of the conventional shoe shown in dotted lines), and the toe of the shoe is Area 11z (area 11b of the ball of the foot does not bend!) can be further bent when walking to a position 23'', also shown in dotted lines. It is not necessary to cover the entire foot as shown in Figure 8.As shown in Figures 7 and 9a, the sole of the present invention is also suitable for sandals and slippers.In this case, not only the insole 4 but also the sole 14 has the advantage that the overall contour of the sandal can be adapted to the contour of the sole of each person's foot, i.e. to the user's foot.This not only provides a perfect fit, but also improves the appearance of the sandal when worn. The sole 14 in this case also consists of three layers 4, 10a, and 3, of which the center 10
A is the rigid core and extends to the toe. However, the thickness is not uniform, and it gets thicker towards the heel, so the outsole only needs to be the same thickness, and you can just attach a simple plate-like outsole with a regular pattern to the rigid core. That's fine. If the same thickness of the rigid core 10 is desired in order to reduce costs, a wedge core 19 (not shown, see FIG. 5a) can be added in the case of sandals as well.

The band 5 of the sandal is fastened to the rigid core 10a with, for example, a nail 8 in a conventional manner. Alternatively, the desired band may be passed through a slit (not shown) extending horizontally through the thick rigid core 10a or 10b. In the case of this sandal 1 (Fig. 7), the tip 11z of the outsole can also be shaped like that of a shoe (see Fig. 6), but in the case of sandals, each time the heel steps, the tip 11z of the outsole moves slightly away from the insole 4. This is not as important as in the case of shoes, since they lift. Although chamfered shapes at the toe and heel may be preferred in other cases, the sandals of the present invention may be free of chamfers as shown in FIG. 7 for the same reason.

Of course, when forming the shoe 9 shown for example in FIG. 1 or 5a, a rigid core 10a or 10b of non-uniform thickness
It is also possible to use The anatomically shaped, preferably individualized, insole 4 is made, for example, from a mixture of cork and synthetic resin, but may also be formed by bonding two separate layers together. Also in the case of the sandal 1 shown in FIG. 7, the rigid core 10a is curved upward in the tip and/or heel area as shown in FIG. 2, or the toe area is omitted or not omitted. It can also be formed with.

[0035] Is the outsole 3 made of rubber or synthetic resin?
Alternatively, the outsole can also be eliminated. In that case, the lower side of the rigid core 10a serves as the outer sole. However, because it is difficult to match the rigidity to each individual user due to costs, it is preferable to at least give most of the elasticity to the inner sole 4 and reduce the elasticity of the outsole 3, which is subject to wear. is important.

The bottom surface 17 of the outsole 11 shown in FIG. 8 is curved uniformly from front to back, and a pattern (
It differs from the outsole shown in other figures in that it can be attached with a (not shown). This is a desirable feature for some types of footwear, as it provides a soft gait. At the rear end of this outsole 11, in this case, a protruding lip 26 (Fig.
A bow-like curvature 18 is provided without a curvature (see ), and it becomes thinner towards the tip region 11z.

FIG. 9 shows the inner sole 4, the rigid core 10b, and the outer sole 11.

In addition, when fixing spikes or studs to the rigid layer, it is recommended to provide a recess in the outsole and the wedge-shaped intermediate layer that has a larger diameter than the recess in the rigid layer to receive the head of the spike or stud. desirable for.
