Description

Steel frame snowmobile sports shoes

Technical Field

The utility model relates to a professional sports shoes field, concretely relates to steelframe sleigh sports shoes.

Background

The steel frame snowmobile sports is a game item of Olympic Games in winter and is a slide racing game item. During the competition, the athlete can run on the ice, jump on the steel-frame snowmobile, and the head of the athlete is forward, the athlete can lie prostrate on the steel-frame snowmobile, and the athlete wins when the athlete wins the competition by sliding on the inclined and curved ice road of 1200-1300 meters. When a player lies prone on the steel frame snowmobile to slide, the sole of the sports shoe worn by the player faces upwards, and the heel of the sports shoe faces forwards (as shown in figure 1). Because the sliding is carried out at a high speed, the highest speed per hour can reach 140 kilometers per hour, and the air resistance borne by sports shoes can influence the movement speed of the steel frame snowmobile. The heel part of the shoe upper of the existing steel frame snowmobile sports shoe is generally arc-shaped, a large and average wind-hitting surface is formed in high-speed sliding, and large air resistance is generated. Therefore, the sports shoes of the existing steel frame snowmobile bear larger wind resistance, and the competition result of the steel frame snowmobile sports is influenced.

Referring to fig. 2, fig. 2 shows a steel frame snowmobile sports shoe 1000 according to the embodiment, the steel frame snowmobile sports shoe 1000 includes a sole 1, an upper 2 and a rear piece 3, the upper 2 is fixedly connected to the upper surface of the sole 1, the sole 1 and the upper 2 form a foot receiving cavity enclosing a foot, and the sports shoe 1000 is divided into a front palm portion, a middle shoe portion and a rear heel portion from front to rear. As shown in fig. 2, 3, 4, 5, 6 and 7, the steel frame snowmobile sports shoe 1000 is provided with a rear piece 3 at the rear heel part thereof, the rear piece 3 wraps the rear heel part of the vamp 2, the outer surface of the rear piece 3 is provided with a smooth and continuous ridge line 31, the outer surface of the rear piece 3 intersects with any plane parallel to a first plane to form a first intersection line 32, the first plane is a plane for supporting the sole 1, the intersection point of the first intersection line 32 and the ridge line 31 is the rearmost point on the first intersection line 32, and the rearmost point on the first intersection line 32 is a first rearmost point 321; the ridge line 31 is curved rearward and has a rearmost point, the rearmost point on the ridge line 31 being a second rearmost point 311, the second rearmost point 311 being located in the middle of the ridge line 31. In the present embodiment, the ridge 31 is located on a longitudinal section perpendicular to the first plane, and the first intersecting line 32 is a smooth-line curve. The longitudinal section where the ridge line 31 is located intersects the outer surface of the heel portion of the sole 1 to form a second intersecting line 11, and the common tangent line of the second intersecting line 11 and the ridge line 31 is inclined forward in the top-down direction.
