Description

Shoes with energy storage {ENERGY STORAGE SHOES}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to footwear for providing energy storage, and to rehabilitation of ligaments of the leg muscles, as well as shoes for daily use, sports shoes for running, jumping, etc. Shoes as a means.

General shoes are provided to protect human legs against external influences. According to its intended purpose, it includes a sufficiently rigid and strong sole and an upper connected to it to ensure the position of the sole associated with the foot and, if necessary, to protect the leg from environmental influences.

Depending on the purpose of the shoe, the embodiment of the sole and upper may vary (Bolshaya Sovetskaya Entsiklopediya (Great Soviet Encyclopedia)), furthermore, БСЭ (BSE). Obuv. (Shoes.) Http: // slovari .yandex.ru / dict / bse / article / 00054/16400.

The shoes specified above do not readily affect the manner of human movement. During walking, the person raises one leg, relies on movement on the second leg, moves the raised leg forward and lowers it onto the supporting surface (ground). This process is additionally repeated.

 One of the features of the manner of human movement compared to many of the other mammals is the nature of contact with the support surface of the legs. A person who transfers his / her weight to one leg first relies on the heel of the foot. Then the load is transferred over the foot as a whole.

  The drawback of such a mode of movement when walking is unreasonable energy consumption. The gravity component of each step is totally lost. Body organs that can partially store energy, such as Achilles tendons and ankle joints, do not work effectively enough.

Most animals move in different ways. Initial contact with the support surface (ground) by them is carried out by the front (front) part of the leg (foot). This means that the ankle joints work for warping. Tendons are stretched to accumulate energy, and then there is an additional push of the legs to perform subsequent steps or jumps with the release of energy.

 In humans, support on the instep bone of the first toe and legs only occurs occasionally, for example when running.

Many different variants are well known for improving the efficiency of movement of a person based on the energy stored in the elastic component that deforms during walking and its release upon return of this component to its initial position.

Shoes used primarily for sports are known, most of which are torsion and length about an axis, including support devices implemented as boots that wrap around the shin with a preliminary system of spring-forced levers with spiral screw springs. It is placed in close proximity to the boot sole with the possibility of directional displacement, with it the main part of it descends against the boot sole (see RU Patent No. 2238125, priority 27.04.1998 GB).

When moving, the user of the shoe lifts the legs and boots forward so that they and the protruding levers do not touch the ground, so that when the boots move downwards, the main lever first touches the ground, Overcoming the action of the spring, it is distorted. Thus, the helical screw spring deforms while storing energy to assist in the later description of the movement of the boot in the upward direction.

The drawback of the above specified shoe and its manner of movement is the inconvenience of the manner of movement associated with the great complexity of the design and in particular the need to raise the shoe to a significant height.

Similar principles are used in the creation of devices of applied design under US patent (No. 6840893, priority 29.04.2002). The device described above is also based on the use of a spring that deforms when laying the leg on the support surface and returns energy upon lifting of the leg.

However, the design is too bulky and unacceptable for everyday use.

The shoe has a support element to ensure reliable foot fixation and an option to enclose the turn and calf connected thereto, wherein the rotating joint is positioned on the same axis as the ankle junction to increase the jump operability including the element. Applications are known in the form of high boots provided. The two elements are connected to each other by extension springs (see DE Patent No. 4038511, priority 03.12.1990).

The lack of such technical solutions, such as the complexity of the design, the inconvenient operation, and the inability to use in everyday life, is similar to other analogues: the movement of shoes in such shoes is a significant effort, special technique and quite advanced coordination. It requires a system.

Shoes having a device for increasing jump operability have been selected as a device prototype. The prototype includes a support platform represented by a sole having an element that fixes the foot position relative to the sole. The platform is thus embodied in the form of shoes. The rear part of the platform-the sole is connected by means of a vertical unit to a unit which fixes the unit on the calf of the leg. The lower part-sole of the support platform is connected by means of a hinge and an arcuate spring by means of the lever. The upper part of the spring is firmly connected to the fixing element of the device on the ankle. The lower support portion of the arcuate jump spring is provided with a cover having a radial wear protection face (see US Pat. No. 6840893, priority 17.07.2003).

The use of arched springs allows disconnection with the screw springs, further increasing energy storage efficiency and reliability of device operation.

However, the nature of the leg grounding of the device, i.e. the initial support on the back of the leg and the rapid movement of the body mass of the entire idea, has not only changed, while it has become clearer. Operation of the ankle joint and Achilles tendon does not have a substantial impact on jump efficiency. The deformation of the spring is only nourished when the human mass is consumed.

The use of shoes with such a device also involves the drawbacks described below;

Substantial complexity of the design of the shoe with a particular mechanism;

-Impossibility of use for increasing the efficiency of the usual walking process, copying of daily use;

The process of movement requires an ascent to a significant height of the bridge;

The process of movement requires considerable labor, special skills and excellent mobility cooperation.

It is an object of the present invention to provide a simple, daily life, sports, medical and the like, which efficiently utilizes not only the mass of a user but also the conversion of his / her muscle energy for the storage of energy and the pushing of the legs. To create shoes that are easy to use universally.

The above-mentioned object is a shoe having a store of energy from deformation of a lip spring comprising a sole and a component for fixing the position of the foot to the sole according to the invention, in accordance with the invention, the front part of the sole is It is solved by bending down against the rest of the and as a console-locked lip spring, the fastening component also providing a close contact with the spring of the sole of the front part of the sole.

The initial angle between the bent spring and the rest of the sole on the side of the support surface is less than 180 degrees.

In addition, the following matters may be required.

The area of fastening and bending of the spring of the sole may correspond to the beginning of the midfoot, toe bone or close to the heel.

The spring may be made of an elastomeric material or other elastic material.

The initial bending angle of the spring of the sole can be selected depending on the purpose of the shoe and the user's physical capabilities as well as its properties.

The cross section of the spring of the sole can be made constant or variable in length.

The front part of the spring of the sole can be made, for example hook-like, to bend in response to irregular projections of the ground.

As such, the object of the invention is that a lip spring intended for the storage of energy used for its deformation when walking therein and the storage of energy used for the return of subsequent energy upon removal of a load is a component of conventional shoes. It is a shoe, combined with a sole and bent downwards.

The patent investigation showed that the claimed shoe meets the criteria of "newness" and "level of invention".

The shoe can be produced industrially or domestically, so it meets the criteria of "industrial availability".

The core of the invention is illustrated by the figures where presented.

Figure 2-Shoes with synthetic soles and initial angles smaller than 180º
Figure 3-Shoes with an angle smaller than 90º between the synthetic sole and the spring and the rear part of the sole
Figure 4-Shoes with a split spring, such as a compound sole and a hook
Fig. 5-Other forms of deformation in the synthetic solo walk shown in Fig. 1, depending on the physical properties (elasticity, stiffness) of the spring (dotted lines show the initial free position of the spring) and the size of the load;
5a-under load the spring is straightened (the spring and other parts of the sole are on one plane)
5b-under load, the spring bends in the opposite direction of the initial position.
5c-with insufficient effect of body mass or insufficient muscle working force, the rigid spring does not reach a flat state. It bends under load and nevertheless remains under an angle that is wider than the initial angle between the spring and the rear part of the sole, but less than 180 °.

The claimed shoe includes a sole 1 and an upper 2.

The brush is synthetic. The front part 1 of the sole is an elastic lip spring 3 fixed to the console by the second part 4 of the sole. The console spring is a continuation of the rear portion 4 of the sole 1. In its initial position the spring 3 is bent downward at an angle α with respect to the rear portion 4 of the sole 1.

The overbending area of the sole 1 may correspond to a typical area of the bend, ie the end of the toe, the area of the end of the metatarsal (tilde), or the part connected to the heel.

The shoe upper 2 has the function of fixing the foot position with respect to the sole 1 which includes the function of the component to fix the position of the foot with respect to the bent spring 3.

The shoe upper 2 includes, in part or in whole, the periodic overbending or bending of the sole 1 on one side and the foot on the other side, including the front part thereof, to the sole 1. It can be made of a resilient material that ensures the conditions of tightness.

In a shoe without a user's foot located therein, the angle α between the elastic front part and the sole 1 is less than 180 ° (Figs. 1, 2, 3). The size of the angle can vary. In particular, it may be smaller than 90 ° (FIG. 3).

The spring 3 of the sole can be made of an elastic polymeric material and its properties can be constant or variable along its entire length.

Depending on the purpose, the type of shoes claimed can vary. It may be warm winter shoes, such as boots or high boots, and may be light for summer, for example, sandals or jogging shoes (not shown).

In any particular example, the shoe is manufactured to have a selection condition of periodic spring bending and straightening. The human leg is thus fixed relative to the sole 1 and movable along the spring 3 of the sole 1, or preventing the spring 3 from shifting back to its initial position to resist movement.

The upper 2 may have a conventional form for closed shoes. However, it must provide a situation for the periodic variation of the angle between the parts 3 and 4 of the sole to be within a sufficiently wide range. For this purpose, an insert which is made of an elastic material or which is easily deformable, for example wrinkles, can be contained in the areas affected by stretching and compression.

The shoe upper 2 may consist of or include other fastening components in the shoe, which secure the fastening of the reliable foot, including its anterior, toe and shin portions. The fastening components 6 are:

The toe portion of the shoe upper, which is firmly connected to the front portion of the sole-spring 3 and forms a cavity for positioning the toes of the foot;

 Straps, bands and similar rigid to elastic fastening components surrounding the feet, wherein these or other fastening components also prevent movement of the foot along the sole or parts thereof.

Can be manufactured in the form of

The initial angle between the parts of the sole 1 (the rear part 4 of the spring 3 sole) is smaller than the typical 180 °. The minimum possible angle may even be as small as 90 ° (see Figure 3).

Putting shoes must apply certain muscular forces to rule out significant over-bending of the toe portion of the foot prior to the start of the movement for the initial pre-stretching of the spring (3). In the range, shoes having an angular width around 90 ° or less than 90 ° would be reasonable to use for sporting events or training. Such an effort is necessary for any separation of the foot from the support surface. The use of shoes with an angular width around 90 ° involves obvious risks and therefore requires special practice.

In some instances, the size or shape of the spring section along its length may vary, for example, the cross sectional area of a particular area may be increased to increase the spring stiffness.

The spring may be manufactured by partially wrapping the foot. In this case in a particular area it can have a C-shaped cross section.

The degree of spring stiffness can be selected according to its purpose: "soft springs" for everyday shoes and more rigid springs for sport shoes.

The appearance of the claimed shoe is unusual. The brush is straight (without over-bending) and has clearly limited over-bending, the angle between the parts of the sole (console spring and other parts of the brush) is less than 180 ° typical. In the initial state, the front of the sole is bent downward.

Manufacturing the sole in the form of a console fixing component that is bent downward in its initial position may result in the muscles and tendons of the foot having a periodic deformation of the sole under the user's weight and / or a simultaneous accumulation of energy used for this deformation. To ensure action. As the weight shifts from one foot to the other, the spring of the sole of the first foot tends to be free of weight and return to its initial downward bend position. The spring can return to this position slowly or quickly enough. In this process, the toe of the foot is pushed from the support surface to move the foot forward. The process of movement of the claimed shoe is similar to walking on tiptoe: at each step the user is pushed to the support surface. This push is automatic.

The deformation of the spring during normal walking is mainly provided by the weight of the user. Detachment of the foot from the surface and relaxed foot muscles (the foot does not serve to support the flat position of the spring), the angle between the front and rear portions of the sole back to its initial position due to the spring's relaxation come.

Grounding as a result of bending the spring is performed on the protruding toe of the foot. And only in that case under the weight of the human the brush is straightened and the foot is in contact with the ground wholly or partially. With global grounding, the angle between the front toe portion and the main rear portion of the sole spreads toward the typical 180 °.

However, other characteristics of movement are possible: grounding can occur until it is flat in the heel portion of the foot with simultaneous spring deformation under human weight.

The movement is also possible when the user prevents bending of the spring under the force of the foot's muscles when the foot is not supported against the surface. In this case the sole in the course of the movement remains almost straight and the grounding can be of any kind according to the user's wishes.

Depending on the weight of the person and the strength of the muscles, the maximum spring deflection (the angle between the spring and the rear part of the sole is almost equal to 180 °) or partial spring deflection (part of the sole Angle between them is less than 180 degrees). The user walks with his toes and the rear part of the foot does not close to the support surface.

The initial angle of the spring bend may vary, for example, if such shoes are used by a person who is moderate and not very muscular, it is reasonable to use a relatively small deviation from a typical flat sole, thus the range 165. Use shoes with an initial angle of ˚- 175˚. For young and trained people, the initial angle between the spring and the rear of the sole may be 140 °. Teenagers may prefer more extreme forms with angles close to 120 °. In addition to being a sport for training, for extreme movements, the initial angle may be close to 90 ° or even smaller than 90 °.

It should be noted that the effect from the energy accumulated by the claimed shoe is not only determined by the rate of initial variation of the front portion of the spring-sole. The effect is substantially determined by the properties of the spring, ie the elasticity and stiffness of the material from which the sole of the shoe is made, the geometry of the spring and the like. The more rigid the spring, the smaller the difference in initial angle from the typical angle required to achieve the desired effect of the shoe.

The ratio of stiffness and elasticity is determined by the spring length, for example the area of overbend. The spring may be less rigid than in the rear part portion.

And again, it should be noted that not only the elastic features of the sole are used to make the movement of wearing the claimed shoes easier. For example, the rear portion of the sole located underneath the heel acts as a lever correlated to the connection of the spring and the rear portion of the sole during the spring action of the spring from the support surface. In this case, the action of the released energy accumulated by the spring is supplemented by the action of this lever. The spring rotates in relation to the point of proximity of the console and, in the rear part of the sole, helps to rotate it upwards and affects it.

The nature of the components that hold the foot in relation to the sole is also essential. These components will force the foot of the foot into a brush anywhere in that position, including the spring's initial bending position. In addition, such components (using an increase in angle between the spring of the sole and its rear part up to 180 °) must ensure the possibility of straightening of the partial or the entire sole using the user's muscle action.

The movement with the features described above can be traditional walking, running, jumping, and the like.

Making the front part of the brush in the form of a bent hook makes it possible to use the shoe for rock and rock movement. In this case, one can "catch" the relief of the surface if necessary, and find the appropriate support for the second foot at that moment. The spring presses the front part of the sole to the bent hook-shaped end and with it the toe of the foot with the selected protruding support. The muscle tension then causes the person to straighten the spring and separate himself from the support, moving his / her weight to the other foot.

Such shoes make it possible to effectively use the resources of a person's body, in particular to make full use of his / her weight and to ensure the effective functioning of foot muscles and tendons.

The above-described implementation makes it possible to effectively use the user's weight as well as the muscle action for the storage (accumulation) of energy and its transfer for pushing the other foot, making the shoes light, simple and easy to use.

The sliding of the state in which the claimed shoes are worn is carried out as follows: A person selects a shoe having the most appropriate characteristics of the spring 3 and the fastening component. In order to wear the claimed shoe on his / her foot, a person may bend his / her foot down along the brush (1) under the influence of a fixed component, or in the process of wearing the shoe on his / her foot The spring should be straightened by muscular effort to increase the angle between the spring 3 and the rear part of the sole 1 in part or in whole to the maximum of 180 ° possible,

The person further stands on the support surface (ground), in which the body weight of the person acts on the spring. Under its action, the spring 3 is deformed and the angle between the parts of the sole 1 reaches almost 180 °.

Then the man starts to move, he continues to stand up for another idea and raises one foot. By raising the foot, the spring is freed from the influence of the person's weight. If the user does not apply a particular muscle force, the angle between the spring and the sole is reduced to its initial size by pushing forward and forward simultaneously on the foot. The feet of the legs are bent partially or completely down along the baking brush. This foot is further lowered to the support surface. The foot touches the support surface at its tip. And only then, overcoming the action of the spring, the foot deforms it at an angle of 180 ° and the leg is fully supported against the foot.

A person with large masses and trained muscles is fully supported against the foot surface even with a rigid spring even during his / her walking. A person with a small mass and weak muscles may lack the strength to fully deform the spring, so he will only support a part of the foot, as when walking on tiptoe.

The utility of the shoe in connection with the use of the accumulated energy will be reduced unexpectedly if the person is primarily supporting the heel by putting the foot down. In this case the front part of the foot bent down along the brush remains bent. The legs are supported only against the heel.

And if, during movement, the heel is lifted off (with support for the tip)-pushing off the tip from the first support surface, the spring acts most effectively on the tip of the foot.

The claimed shoe opens up interesting possibilities for jumpers. They can do it at the optimum moments that prepare their bodies for the jump and substantially increase their efficiency. To do this, the user performs a preliminary "swaying": partial compression and release of the spring due to muscle forces which slowly increase the amplitude and frequency of the vibration. When the spring is deformed to its maximum, he jumps. In this process, the effect of resonance can be induced and used.

The same action can be done in training, especially for running. Shaking ensures a stronger spurt at the start.

You can sit, stand, walk, run and jump at a late or fast pace with the shoes you are charged for. The claimed shoe can be used by mountaineers.

With the correct selection of the initial angle and the provision of the ability to deform the upper part 2, a test was conducted to confirm that the claimed invention is comfortable for any type of user and that the speed of movement is significantly increased. In the process, the force consumed by the user for movement due to the deformation of the spring is not substantially different from that consumed for movement with conventional shoes.

The examples presented are not intended to be exhaustive in nature and other configurations and modifications may be made without departing from the spirit of the invention as set forth in and defined by the claimed claims.
