The invention relates to a Shoe with a sole Assembly with unstable structure to restore and/or maintain the statically optimal body posture and healthy dynamics of walking and running, for children and adult users, containing the upper and the sole Assembly, designed to be consistent with the physiology of the normal rolling gait, in which the sole Assembly attached to the top and in which the sole Assembly includes: wearing layer adapted to contact with the ground; the bottom layer attached to the wear layer; the upper layer is attached to the bottom layer; and plate rigidity, located so that it is in contact with the upper layer.

There is a fundamental human need in the movement of his body, including walking. However, with the advancement of civilization, the implementation of this need became more and more detached from the natural environment. Walking barefoot on natural terrain members of the previous generations turned into "active walk" by laying tracks and constant adaptation to the irregularities of the earth, who are forced to use (load) muscles to the extent appropriate. This long muscular load has resulted in the maintenance of healthy circulation and significantly ur is vnam metabolism in cells and tissues. Flat, artificial the territory of today's cities together with the trend of wearing shoes flat shoes in the collection and sedentary lifestyle often lead to incomplete use of muscles and muscle dysfunction. The consequences of this include muscle weakness, muscular imbalance and overload joints. Inadequate muscle load for an extended period of time leads not only to the beginning of the pathological processes in the musculoskeletal system, but has an indirect negative impact on other units and agencies. It lies at the basis of certain diseases of civilization, which were unknown to the people of previous generations.

Ergonomically optimal gait can only be achieved by walking barefoot on uneven ground. Long ago, it was realized that the optimum gait (gait when walking barefoot) can be approximately reproduced by the use of footwear, when worn which can imitate unstable, uneven terrain. Wearing such footwear induces the muscle tension detecting the orientation (deep muscle)that you want to unload the joints and maintain physiological posture of the body.

In the International application WO 01/15560 disclosed shoes for dynamic walking rolling gait. The footwear includes an upper for support of the foot of a user to the which attached to the sole Assembly, adapted to create the feeling of walking barefoot. To accomplish this, the sole Assembly includes lower and intermediate layers. The middle layer is made of a relatively hard elastic material, whereas the lower layer is made of a softer elastic material. The bottom layer contains arcuate segments, creating a common format suitable for playback rolling gait. The disadvantage of this solution is that it is not possible to adequately simulate walking on natural terrain due to the fact that between harder and softer layers formed by the axis of rotation. In addition, the user must maintain the balance and ergonomically optimal posture of the body through the application of constant conscious effort (conscious walk"). An additional disadvantage of the invention is that the soft bottom layer can be easily damaged during use.

In the description of European patent EP 0999764 disclosed shoes, designed to enable playback rolling gait. According to the invention, the sole Assembly attached to the top of the Shoe contains the body of the base and the coating layer (wear layer). The axis of rotation is located in the wear layer in the metatarsal region, relative to which it can be rotated front and back. In the blast between the center of the foot and heel, between the body of the sole and the wear layer is formed a recess in which is inserted a soft, elastic element, distributing the load. Through the shoes according to the invention it is possible to provide natural rolling behavior of the foot during walking, with a uniform load distribution. The disadvantage of the invention is that due to the fixed nature formed the axis of rotation of the shoes is only partly suitable to simulate natural running surface and, thus, to activate the muscles of the way, close to the natural. An additional disadvantage is that for wearing proposed in the invention of shoes you want and exercise, and constant attention from the user. If the user suffers from a serious form of flatfoot, he must constantly focus on preventing pronation of the ankle (which can cause additional damage) when you walk in the proposed invention of shoes. If there is no training (as is the case when the user is a small child) to perform a "conscious walking, wearing proposed in the invention of shoes can lead to additional damage. Therefore, children or people with serious health problems may not use the proposed invention is bowl without medical supervision. Another disadvantage of the Shoe according to the invention is that it is prone tendencies damage on the edges of the soft layer that distributes the load.

Known solutions include corrective insoles, especially for children, and corrective modification of the heel part to prevent pronation of the heel bone and ankle. This built-in insole included in children's shoes Siesta (Siesta), produced by the factory Sabaria Shoe Factory c 1970 Insole supports the arch of the foot and is designed to prevent pronation of the ankle. These previously known solutions provided passive maintain the arch of the foot to create the corrected position of the joints. However, this optimum position supported by the insole instead of providing the active work of the muscles. This hindered the strengthening of muscles, and therefore they could not maintain the optimum position without support. Thus, this solution provides rather symptomatic than etiological (final) treatment. Also, this footwear does not provide the ability to create a sense of instability and maintain the tone of the muscles.

The purpose of this invention is to provide a Shoe to simulate the uneven surface of the earth, wearing which the user is not required to perform a "conscious walking. The invention is mainly aimed at the creating shoes for kids muscles and joints are still intact and, thus, are the best objects for prevention. The beneficial effects of the invention, of course, also applies to shoes intended for young people and adults. In these cases, the goal is to stop for a healthy static and dynamic walk, to stop pathological processes, adversely affecting the musculoskeletal system. An additional aim of the invention is the creation of a sole Assembly in which the side surfaces of the layers, especially the lateral surface of the more elastic layers, protected from mechanical shock. One additional goal is to create a cheaper and lighter products by simplifying the process of manufacturing a sole Assembly.

The invention is based on the idea that walking on a simulated uneven ground surface does not require conscious action ("perceived distance") from the user, if the bones of the foot support in a flexible way. When using the sole Assembly made in this way, prevents pronation of the ankle, but at the same time supported the incentives needed to be active muscles. Part of the view is that the more elastic layers of the sole Assembly can be protected from mechanical damage, if the symptom is simoudis layer is made thus so he advocated the edges of the other layers of the sole Assembly. Significant protection of the sole Assembly can also be provided by locating the side surfaces of the firmer bottom layer so that it has a concave shape when considering the front and back of the sole Assembly, to thus ensure conditions under which under load more hard-wearing layer and the top layer would have been surrounded by the bottom layer. Also part of the view is that the plate stiffness, usually located between the sole Assembly and the height of shoes can carry the load and to ensure proper load distribution when introducing them to the sole Assembly with unstable structure. Thus, there is no need to incorporate additional elements, leading to an increase in the weight and cost of the sole Assembly.

Proposed invention the objective is implemented by creating a Shoe that is described in the introduction of this document, in which the bottom layer, which is covered with a running surface that is attached to the wear layer so that the wear layer is performed at least at the side surface of the lower layer and the upper layer, which is coated running surface was attached to the bottom layer, where the top layer includes a support ledge adapted to predator is the pronation of the ankle and is made in size so to its size, at least, was consistent with the size of the arch of the foot and to the material of the lower layer was more elastic than the material of the upper layer, and the plate stiffness was designed in such a way that it is consistent with physiology rolling gait, and that it was located in contact with the top layer, also located so that they were covered with the running surface and to have a size in cross-section, decreasing to toe.

Previously known footwear designed to maintain or restore health, includes a sole Assembly, designed to be able to perform a rolling gait. The sole Assembly, which provides the ability to perform rolling gait, have a curved running surface, rather than rigid and essentially flat soles, while the area under the ball and heel is slightly raised above the ground. The degree of lift above ground is chosen so that during normal walk part of the foot under the ankle bone first touched the ground, and the part under the toe was off last after continuous rolling motion. This is consistent with the physiology of walking barefoot. The sole Assembly is designed in such a way that it is consistent with Phi is biologia rolling gait, disclosed, for example, in document EP 0999764. As such, the sole Assembly made in accordance with the physiology rolling gait, disclosed in the prototype, it is herein omitted the detailed description. This sole Assembly may be manufactured by performing hardness plate so that it is consistent with physiology rolling gait, where other elements of the sole Assembly glued to each other and to the plate stiffness.

Footwear according to the invention includes a sole Assembly and an upper attached to the sole Assembly. The top can be made from materials commonly used in the Shoe industry, for example, of leather, artificial leather, textile or plastic. The top may have a conventional configuration of a boot, athletic shoes, boots or even sandals. Shoes may also contain internal as usual lining, where the material and configuration of the pads are identical to the solutions known in the art.

The sole Assembly of the Shoe according to the invention is assembled from: wear layer; the lower layer is attached to the wear layer; the upper layer covering the lower layer; and hardness plate in contact with the upper layer. The role of the wear layer is to protect the underside of the sole Assembly otrestavrirovannogo wear. The wear layer according to the invention is, at least the side surface of the lower layer. In addition to providing protection from wear and tear of the surfaces in contact with the ground, due to this configuration, the wear layer protruding in the lateral direction of the edges is possible to protect the side surfaces of the softer, more elastic elements of the sole Assembly from mechanical damage. This configuration has the same effect as the configuration in which the wear layer completely surrounds the side surface of the sole Assembly, but the latter is much easier and more aesthetically appealing. According to a preferred variant of the invention, the wear layer completely covered the front part of the sole Assembly and effectively protects the Shoe from damage, wear and tear. In a preferred embodiment, the wear layer is made from an elastic plastic or rubber, provides a good grip.

In an additional preferred variant of the invention, the side surface of the lower layer is essentially perpendicular to the wear layer and the running surface and speed connected with wearing layer. In the context of the present description under t is rbinom "essentially perpendicular" you see, the deviation from perpendicularity is less than 5°. According to another preferred variant of the invention, the side surface of the lower layer is located at an acute angle to the wear layer and the running surface where the side surface of the lower layer are connected flush with a side surface of the wear layer.

The bottom layer of the sole Assembly attached to the wearing layer of the permanent way, by gluing or welding. The bottom layer is covered with all the running surface, which means that it runs from the back of the ankle to the edge of the sock and has a width consistent with the width of the track of the foot.

The lower layer is preferably made of a thermoplastic material, particularly of soft, elastic polyurethane. The bottom layer can be made of plastic materials of different elasticity in the case of manufacturing shoes of different sizes, to match the elasticity of the weight of the user. According to another preferred variant implementation of the lower layer contains through holes made for regulating deformation of the lower layer. Soft, elastic bottom layer creates the feeling of walking barefoot on uneven ground, thus stimulating muscle activity. Feeling the rough surface of the land required to consider the mix to constantly changing conditions, caused by the sole Assembly with unstable structure, causing the muscles to strain under the influence of reflex, which, in turn, frees the joints from stress and helps to maintain physiological posture of the body. A healthy walk or dynamic running is important not only to prevent ailments of the joints or muscles, but has a beneficial effect on the activity of other organs of the body. Prolonged activity of underlying muscle, caused by the use of a sole Assembly with unstable structure, improves circulation and metabolism in cells and tissues.

According to an essential characteristic of the invention the top layer, which is covered with a running surface, attached to the bottom layer. The bottom layer may be attached to the bottom layer by welding, gluing, etc. According to a preferred variant of the invention, the top layer is made from a thermoplastic material. In the present description, the term "running surface" is used to denote the surface of the sole Assembly, which supports the foot. The running surface can be defined as a plane figure bounded by a curved line coming from the rear end point of the ankle to the tip of the sock, the greatest width of which is in the area where it touches the bones of the arch of the foot. Stop OPI is moved on the carrier surface in areas where it touches the ankle bone and the bones of the arch of the foot, the so-called anatomical reference distance. Between these two areas of the foot bones form an arch. Soft soles used in ordinary shoes with a sole Assembly with unstable structure, can cause pronation of the ankle, which can be compensated only by "perceived distance", i.e. through the deliberate rejection of the ankle outwards. According to the invention is more solid, relatively less elastic top layer attached to the bottom layer. The top layer includes a support ledge, at least in the area under the arch of the foot. The supporting protrusion is adapted to prevent pronation of the ankle, and because of this eliminate the need for careful use. Adding a relatively rigid supporting lugs at the outsole Assembly makes optional "learning to walk again" as proposed in the invention of the Shoe sole Assembly with unstable structure and a constant focus on maintaining balance. Also thanks to the support ledge opens the possibility of using the proposed invention footwear for young children who still do not understand the instructions. With support ledge provide flexible support for the ankle joint, and at the same time also supported the stimulus for muscles to save f is zoologicheskoi posture of the body. Support extension can perform its role if it is at least equal to the footprint of the arch of the foot. The words "the imprint of the foot arch" here understand the area where the surface of the sole of the foot does not touch the running surface, while the foot rests (is) on it.

According to a preferred variant of the invention, the overall length of the support ledge is equal to at least the anatomical distance between the reference points of the running surface, i.e. the distance between the reference points on the driving surface from the heel bone to the bones of the arch of the foot, and the maximum width of the support ledge takes place, at least from the middle region of the sole Assembly to its midline.

The thickness of the support ledge is chosen so that it was possible to provide a flexible support for the ankle. To achieve this, the area under the support ledge of the bottom layer should be thick enough to ensure the "unstable environment" for the foot, but it should not be too thick, so don't get lost effect of ankle. The greatest thickness of the support ledge should be preferably 60-80% of the maximum thickness of the lower layer. In a preferred embodiment of the invention the maximal width of the support ledge is three quarters of the greatest thickness of the lower layer.

Supporting ledge is preferably made of the same material, made of top layer. According to additional favorable variant implementation of the top layer and the support protrusion to form a single element, but the structures in which the top layer and the support ledge performed as separate items (even made of different materials), permanently bonded together, for example by gluing, also fall under the scope of the invention.

In another preferred embodiment of the invention the abutment ledge connected smooth transition from the upper layer at its end, near the toe. Maintaining the calcaneus through the normal hard sole makes walking too painful ordeal for patients suffering from joint pain, especially arthritis. In a preferred embodiment of the proposed invention the sole Assembly includes a support ledge that ends cut at its end near the heel so that it didn't cover the anchor point for the calcaneus on the travel surface. With this construction of the supporting ledge of the calcaneus for the soft bottom layer, while at the same time, the beneficial effects of the invention are still provided to the user by supporting ledge. The slice may be limited by a plane or curved surface. According to a preferred variant is sushestvennee of the invention the surface of the cut is limited by the plane the angled 18-30° to the midline of the sole Assembly. According to a particularly favorable variant of implementation, the angle between the bounding plane of the slice and the middle line of the sole Assembly is 21°.

According to a preferred variant of the invention, the additional correction of pronation of the ankle provide, if required by the location of the surface wear layer adapted to contact with the ground, and the lower layer by lift. In this embodiment, the wear layer is placed at an acute angle, preferably at an angle 83-87° to the travel surface.

According to the invention the plate stiffness is in contact with the upper layer. The plate stiffness is made from solid plastic material, for example PVC or sheet plastic, reinforced with fiberglass, and it has a curved surface consistent with the physiology rolling gait. Plate stiffness feature so that it was covered with a running surface, and it has a size in cross-section, decreasing to toe. With this design is the plate rigidity is ensured even distribution of load and transfer the load to the sole Assembly without disturbing its instability. Plate stiffness and the upper layer of glue and the and weld together. Covering plate, introduced to facilitate the connection of the bonding, and/or the support plate is adapted to contact the edges of the top and contains the neckline can also be attached to the side of the plate stiffness connected with the upper layer.

The design of the sole Assembly, in which the side surface of the lower layer has a convex shape, when considering the front and rear structures of the sole Assembly, is also the subject of the present invention. In a preferred embodiment, the side surface is curved. Structures in which the side surface of the lower layer is limited by the planes, also included in the scope of the invention. The side surface of the lower layer as a whole can be bent, and it can be attached to the concave shape, and substantially concave configuration of the side surface is also included in the scope of the invention. The term "essentially concave configuration of the side surface includes structures in which the side surface of the lower layer is, in special cases, surface, torn holes or containing the tabs. The front and back surfaces of the sole Assembly can be accomplished without having concave side surfaces, especially in case of wearing layer, protruding as far as the edge of the running surface raised above the ground. In p edocfile embodiment of the invention the cross-section of the concave surface has a circular arcuate bounding line. According to an additional preferred variant implementation of the cross-section of the concave surface is limited by straight lines.

The concave configuration of the side surface serves to protect the lower layer is made of a more elastic material. The concave surface is made in size so that when the surface of the sole Assembly is exposed to higher loads, for example, as the user steps on the stone or object with sharp edges, the edges of the wear layer and the upper layer come into contact, the surrounding material of the lower layer. In this position, soft, elastic material of the lower layer is protected against tearing and abrasion. With this design of the sole Assembly significantly increases the service life of shoes.

The top layer 5 includes passing down the abutment projection 9, as shown in Fig.6, which is at least the same size print of the arch of the foot. The abutment projection 9 is connected to the top layer 5 along the plane in which the cross-sectional shape of the support ledge is a flat shape having longer sides in contact, respectively, with an average edge 11 of the sole Assembly and an average line 10, with the first shorter side direction essentially perpendicular to the middle line 10, and the second shorter side ends in the slice 12. Off line 12 is at an angle α to the middle line, while the slice is located before the reference point of the calcaneus. The angle α is equal to 21°. The top layer 5 and the abutment projection 9 provide flexible support for the foot when walking and heel support firmer, softer bottom layer 4.

The top layer 5 and the lower layer 4 are glued together. The bottom surface 13 of the lower layer 4 covering the entire running surface 8, glued to the wear layer 3. The bottom layer 4 is made of a more elastic polyurethane in comparison with the upper layer 5, which provides an unstable condition of the foot, successfully simulating barefoot walking. In the lower layer 4 with holes 7, as this is still the ANO figure 6. Holes 7, on the one hand, are made to reduce the weight of the sole 1 in the collection, and on the other hand, to enable modification or regulation of elasticity of the lower layer 4.

On transverse sections of the sole 1 in the collection (in different planes) clearly shows that the sole 1 in the collection is made so that its end part in the direction toward the toe and heel were raised to a certain extent (by means known in the art), consistent with the physiology rolling gait. The bottom layer 4 is limited to the front surface 20 and rear surface 21 and side surfaces 14, 15 are limited to the lower layer 4 and the top layer 5. As the lower layer 4 and the top layer 5 are arranged in such a way that they covered each other, the respective front, rear and side surfaces of the lower and upper layers are in the same plane. Side surfaces 14, 15 of the lower layer 4 and the upper layer 5 are essentially perpendicular to the running surface 8 and the wear layer 3, as shown in figure 4, 5, so that these side surfaces formed of a single plane. The plane lateral surfaces 14, 15 is located at an angle of 5°, where the slope is made to the middle of the sole Assembly. The wear layer 3 serves for the lateral surfaces 14, 15.

SUBSTANCE: shoes include a shoe upper, which is fixed to external parts of a sole, comprising an upper end part and a lower end part. The external parts of the sole have at least two support elements (41, 42, 43) at the heel level made of a cushioning material and arranged accordingly at the side edge and at the middle edge of the shoe sole. Each element (41, 42, 43) stretches in vertical direction substantially from the end upper part to substantially the lower end part of the sole. The support elements (41, 42, 43) are made with the possibility of deformation substantially independently on each other.

FIELD: manufacture of soles with pins for shoes.

SUBSTANCE: flexible sole has lower working surface consisting of less flexible outer layer, upper surface, more flexible inner layer positioned therebetween, and inwardly retractable pins fixed within inner more flexible layer. Each pin has anchor part embedded into more flexible layer, tip protruding beyond plane of lower working surface, and core which connects anchor part with tip. Flexible material is non-uniform in flexibility extent and has lower flexibility in zone adjoining outer part, near sole surface, and higher flexibility in zone adjoining inner part of sole. Anchor part of pin is embedded into sole in its more flexible part so that body of more flexible material is provided between sole and upper surface. On wearing of shoes and applying of compressive deformation force to sole lower surface, tip is retracted into sole under the action of force applied by anchor part of pin to more flexible inner part. Less flexible outer part of sole provides wear resistance on contacting of lower working surface of sole with rigid surfaces during wearing of shoes. According to another version of sole, lower surface of sole has annular slots running around pin tips to enable bending of tips upon application of pressure to sole lower surface during walking, for example, over rigid surface.

EFFECT: improved adaptation of flexible sole equipped with pins to variable pavement or ground surface and to user's weight so that pins readily cooperate with said surfaces into which these pins are designed to penetrate.
