Description

The utility model relates to sports shoes, in particular, to hockey boots.

Famous hockey skates consist of three main parts: a boot, a glass for attaching the blade (rack) and the blade itself. An ordinary hockey skate has a high boot. To protect the foot from bumps and fixation of the foot of the boot, it is made rigid from a combination of plastic, thermoplastic materials, artificial or genuine leather. For reliable pressing of the foot to the boot, tight lacing is applied from the beginning of the toes along the ankle joint to the beginning of the tibia. For even distribution of lacing pressure and additional protection of the foot from impacts, an elongated tongue is used made of a thick layer of felt or fabric duplicated by foam rubber. But in the process of skating, when bending the leg, a local area of increased lacing pressure on the leg appears at the bend of the ankle joint, which causes a painful sensation, and the more bent the leg, the greater the discomfort (see. Modern hockey skates. Technologies, choice. / / Magazine "Sport Store". - 2011. No. 20. S. 32-36).

Known RU patent for the invention No. 2180792, publ. 03/27/2002, This patent describes a volumetric air pad for a shoe boot, which is a protective shield having a three-dimensional structure, and curvature corresponding to the upper surface of the foot. The volumetric air pad for the shoe shoe includes upper and lower sheets, all peripheral edges of which are sealed to form a hollow inner part and including longitudinally located peripheral side edges. The said sheets form two longitudinal surfaces, made in the form of a curved inward air strip, and the cross-section lines of each of them are curved. The disadvantages of this design include the fact that when bending the leg, in the place of the bend of the ankle joint there is a local zone of increased pressure on the lacing of the leg, which causes a painful sensation.

In the hockey boots market, from widely available sources, for example, on the global Internet, information is known that to reduce the increased pressure of the lacing on the leg, an insert in the tongue is used, for example, MUNARI-900S skates, made in Estonia (see the application description on 2 sheets in 1 copy). The hockey boots presented in this application are selected as the closest analogue (prototype). These boots have an insert in the tongue of a hockey boot in the shape of a body of double curvature like a hyperbolic paraboloid or saddle. When bending the leg, this insert experiences the greatest tension in the place of the directly bent ankle joint. The disadvantages of this design include the fact that this design does not provide increased strength of the insertion into the tongue at the location of the bend of the ankle joint, which can lead to its destruction during use and create inconvenience when using the boot.

The technical result of the claimed utility model is the creation of a tongue design that allows you to evenly distribute the lacing pressure on the leg when it is bent while providing the necessary strength when bending the leg and additional protection against shock.

The claimed technical result is achieved by the fact that the insert in the language of the hockey boot has the shape of a body of double curvature like a hyperbolic paraboloid or saddle. The insert into the tongue of the hockey boot in the transverse and longitudinal sections has a variable thickness maximum in the center of the section and gradually fading to the edges. The insert in the tongue of the hockey boot in plan has the shape of an elongated trapezoid with rounded bases. The insert in the tongue of the hockey boot is made of plastic.

This form of insertion into the tongue of the hockey boot allows you to evenly distribute the additional lacing pressure on the leg when bending the leg. The cross-sectional shape allows you to increase the flexibility of the insert while increasing its protective properties, since the greatest lacing pressure and the likelihood of striking are in the place where the insert thickness is maximum, which ensures the necessary strength when bending the legs and additional protection against shock.

Fig. 1 shows an insert into the tongue of a hockey boot, general view; Fig. 2 shows an insert into the language of a hockey boot, top view, Fig. 3 shows a section along the line A-A, Fig. 4 shows a section along the line B-B.

To ensure uniform distribution of lacing pressure on the leg during its longitudinal bending and additional protection against shock, an insert is installed inside the tongue of the hockey boot. The insert in the tongue of the hockey boot is made of a sheet of plastic and has the shape of a body of double curvature like a hyperbolic paraboloid or saddle. In plan view, the insert has the shape of an elongated trapezoid with rounded bases. Both in longitudinal and in cross sections, the insert has a variable thickness. The thickness of the insert is maximum in the center of the section and smoothly converges to zero at the edges.

The work is as follows.

The insert is fixed inside the boot tongue, closer to the outer surface, at the bend of the ankle joint and covers part of the foot and lower leg in this area. The shape of the insert in longitudinal section along the line A-A allows you to freely bend the leg in the ankle joint, the shape of the insert in the cross section B-B allows you to evenly distribute the additional lacing pressure on the leg when bending the leg. The shape of the cross-section and longitudinal section allows to increase the flexibility of the insert without weakening its protective properties, since the greatest lacing pressure and the likelihood of an impact occur at the top of the convex part of the leg in the place where the insert thickness is maximum.

Insertion into the tongue of a hockey boot can be performed on existing equipment, for example by molding, using available technical means.

The insert in the language of the hockey boot has a simple design, is safe to use and allows you to increase protection and comfort.
