Sole for sports shoes and footwear
The soles of sports shoes, which includes on its lower surface two connectors for attachment to sports equipment, offset relative to each other in the longitudinal direction of the Shoe and arranged in the transverse direction of the Shoe. The first means of connection is located at the level of the front edge of the sole, or at the level of the anterior edge of the toes. The second means of connection is located behind the first connection means and, in fact, before the area metatarsophalangeal joint (). The first means of connection may be located at the leading edge of the form for the manufacture of shoes, the first means of connection is located at the level of the anterior end of the toes or directly in front of him. The technical result achieved by this sole is the creation of a sole that meets the requirements of control travel/guides feet without compromising its comfort, namely, optimal control and guide body glide or sport equipment, which can be achieved only through the constant contact of the feet with him and/or a certain torsional stiffness of the sole that is incompatible with a bend or move his legs. 2 S. and 4 C.p. f-crystals, 2 Il. In these sports and, in particular, cross-country ski experimented with various ways of fastening the Shoe to sports equipment.The traditional way of mounting is a mounting Shoe on the flat ski with the help of brackets, interacting with the front protruding part of the base and clamping the part to the ski.This method of installation prevents full stride leg as the leg is secured across the front.To eliminate this drawback, it was proposed various systems of the hinged mounting of the Shoe on a flat ski with the axis of rotation attached to the Shoe in the transverse direction.Testing of the various provisions of this axis in the front of the Shoe, at the level of the metatarsal zone and so on, with more or less satisfactory results.The problem essentially lies in the fact that while maintaining comfort when used to find a compromise between two completely contradictory requirements, namely: - the tee from the sport, which requires some flexibility soles bending, and this flexibility varies from sport to sport, optimal control and guide body glide or sport equipment, which in theory can be achieved only through the constant contact of the feet with him, and/or a certain torsional stiffness of the sole that is incompatible with a bend or move his legs.This problem was partially solved in the patent FR 2739788, providing for a system boot/device mounting Shoe to sports equipment, in which the Shoe contains two tools anchoring formed by two transverse axes located one in front of the Shoe, the other almost at the zone level metatarsophalangeal joint, in which the mounting device provides rotation of the Shoe around the first axis anchoring and creates a permanent elastic return force on the second axis anchoring in the direction of sports equipment.Thus, the existence of means of elastic return of the boot towards sports equipment, not to its front part, as in the known hitherto devices, and in the direction toward the rear fastening means these shoes allows con is a life course approach allows thus to combine the problems of growth and control/guidance Shoe for sporting equipment and provides thus in principle the optimal course of his feet.Patent FR 2739788 provides for accurate placement of the second transverse axis at the level of the metatarsophalangeal joint.Experience shows, however, that the placement of this axis on the level of the joint causes inconvenience, because the bending of the legs at this level is carried out around the hard point.The exact placement of the first axis is also not obvious. Indeed, the farther this axis is shifted forward, the greater the eccentricity, if the axis is positioned too forward, move legs will be broken, because the athlete will not have the feeling of free rotation.On the contrary, the course will not be optimal, if the first axis is positioned too backward relative to the edge of the Shoe.The present invention is therefore to overcome these disadvantages and offer soles for sports shoes that meet the requirements of control travel/guides legs without sacrificing comfort.This problem is solved thanks to the sole of the sports Shoe according to the invention, which is of a type that includes on the lower surface of the two connection means for attachment to sports equipment, offset relative to each other in the longitudinal direction of the Shoe and placed in the transverse direction of the Shoe, so that asaeda behind the first means on the merits before the district metatarsophalangeal joint.Due to this placement is essentially guaranteed that the second means of connection will come into effect only at the end of rolling on the metatarsophalangeal joint, and therefore, would not violate this movement.In a preferred variant implementation of the invention the first means of connection is located at the level of the anterior edge of the toes, or just before it.This placement also allows you to ensure the movement of the slide on the toes in the absence of solid points.According to another preferred variant implementation of the invention the first means of connection placed at the level of the leading edge of the form to make the footwear.In the following preferred variant implementation of the invention the second means of connection is 50 mm from the first means of connection.Both connectors are attached to the shoes separately.In a preferred variant implementation of the invention, each tool connection has a transverse axis.In a preferred variant implementation of the invention, at least one slot for bending is made in the sole at the level of each means of connection.The task is also solved by means shall sabreena will be better understood, and other signs will be shown using the following descriptions.Fig.1 is a bottom view of a sole according to the invention.Fig.2 is a longitudinal section of Fig.1 Sole 1 includes a guide groove 3 with a transverse rectangular cross-section, placed along the longitudinal axis 2 of the sole and receiving two transverse axis, the first axis 10 and the second axis 20, forming two connectors, respectively, front connection tool 10 and the rear connection tool 20.As shown in Fig. 1, the first axis 10 is placed at the level of the front edge of the sole, and the second axis 20 is placed behind the axlemetatarsophalangeal joint.Preferably the first axis 10 is placed at the level of the anterior edge of the toes.In practice, this situation is determined by the edge Assembly of the form used to create the uppers in manufacturing. This form must be submitted at number 30 in Fig.2, which shows the position of the axis 10 with respect to its end 31.The second axis 20 is placed behind the first axis 10 in the longitudinal direction in such a manner as to face the axismetatarsophalangeal joint.This position is shown in particular in Fig.1.In practice, for sizes equal to or Wu two axes 10 and 20, equal to 50 mm, allows you to meet this requirement and to combine the freedom of the progress of the foot while maintaining a satisfactory guide.On preferred options run the axis 10, 20 are mounted in the Shoe independently of each other in such a way as not to hinder the bending of the sole.Can also be provided by the slits bend 5, 6, 7, 8 between the two axes 10, 20 and behind the second axis 20 to the flexibility of the soles.It will be noted that the location of the connection sections 10, 20 before each articular area of the foot prevents the formation of hard spots in the course of the foot, and therefore provide a high comfort to the user.Naturally, the present invention is not limited only option implementation, described here as a non-limiting example, but includes all equivalent ways.It also applies to all types of sports shoes, which must be addressed in a similar or equivalent to the problem.
