Field of technology A utility model relates to the field of sports and is intended for use as sports equipment, in particular, a utility model relates to skates.

State of the art

A device is known - a skate for ice hockey (RF patent N ° 19640). An ice hockey skate consists of a support part connected to a runner. In this case, the supporting part consists of a skid plate and, in addition, from a front strut equipped with a plate for the sole, and a rear strut equipped with a plate for the heel. Between the front strut and the rear strut of the supporting part of the ridge there is a central cross member. At the same time, the implementation of the front strut and rear strut of a direct type leads to a concentration of internal stresses, as a result of insufficient reliability.

A disadvantage of the known technical solution is low reliability. The closest technical solution (prototype) is skates

The runner 22 is made in the form of a strip, one of the long edges of which is arched convex and sharpened with the formation of a blade 23. Moreover, the radii of curvature of the said edge of the runner are many times greater than the length of the runner 22. Two short edges of the runner 22 form the front end 12 and the rear end 28 . The length of the runner 22 performed more than the length of the sole 4, i.e. than foot length. The runner 22 is provided with a first strut 9, a second strut 19, a third strut 27 and teeth 11.

The blade 23 is made as a pointed, sharpened in a special way convex edge of the runner 22, while on the side intended for contact with ice, it is possible to make a groove located along the blade 23.

On a concave edge opposite the blade 23, the runner 22 is connected to the first strut 9, the second strut 19 and the third strut 27. The first strut 9 is connected to the runner 22 near the front end 12 and is a continuation of the front end 12. The third strut 27 is connected to the runner 22 on some distance from the rear end 28, while part of the runner 22 from the third rack 27 to the rear end 28 forms a protrusion 29. The connection point of the second rack 19 with the runner 22 is located between the first rack 9 and the third rack 27.

In this case, the sixth edge 10 near the connection with the first connecting edge 8 is located farther from the front end 12 of the runner 22 than the sixth edge 10 near the connection with the runner 22. The sixth edge 10 can be made rounded outward from the first strut 9. The sixth edge 10 passes into the blade 23 of the runner 22 with the formation of the sixth rounding 13. Moreover, if the sixth edge 10 is rounded, its radii of curvature are greater than the radii of the sixth rounding 13. On the sixth rounding 13, acute triangular protrusions, i.e. teeth 11. In the particular case of teeth 11, five are made.

The length of the eighth rounding 36 along the bottom line is greater than the length of the fifth rounding 14 and the length of the fourth rounding 17.

Between the third edge 20, the edge of the runner 22 located between the second strut 19 and the third strut 27, and the second edge 24, a second cutout 3 is formed. The third edge 3 is made of a very short length. The third edge 20 goes to the edge of the runner 22, located between the second rack 19 and the third rack 27, with the formation of the third rounding 21. In the particular case, the third rounding 21 is made from the transition point of the second connecting edge 18 to the third edge 20. The radii of the third rounding 21 are made in several times larger than the radii of the second fillet 25 and the radii of the ninth fillet 37, described below. The edge of the runner 22 located between the second strut 19 and the third strut 27 is made concave toward the runner 22 and is made as a continuation of the third rounding 21. The second edge 24 is made concave towards the third strut 27 with the formation of the ninth rounding 37. The ninth rounding 37 is made inclined to the side of the second strut 19, for example at an angle of 62 to the line, the bottom line. In this case, the ninth rounding 37 near the third connecting edge 26 is located closer to the front end 12 of the runner 22 than the ninth rounding 37 near the connection with the runner 22.

The angle between the tangent and the line drawn through the touch point and the connection point of the second edge 24 with the third connecting edge 26 is, for example, 47. The angle between the specified tangent and the line drawn through the point of contact and the connection point of the third edge 20 with the second connecting edge 18 is, for example17.

An imaginary additional line is drawn to determine the position of the first median line and the second median line. The additional line is parallel to the bottom line and is located at the same distance from the bottom line and specified tangent. The first median line of the second strut 19 passes through the center of the second connecting edge 18 and the middle of the extension line bounded by the second strut 19.
