Problems solved by technology

[0003] After long-term research, the inventors found that there is a significant difference in aerodynamics between softballs and traditional balls, and softballs that simply follow the appearance of traditional balls generally have the problem of poor aerodynamic performance

Embodiment 1

[0017] Embodiment 1, the aerodynamically optimized softball of the present invention is a softball with valves and built-in sand grains. The surface of the softball 1 is formed with an arc-shaped dumbbell ring groove, and the dumbbell ring groove will The surface of the soft ball is divided into a dumbbell-shaped downward-extending flap and a dumbbell-shaped upward-extending flap. The above and below equal means that after the dumbbell-shaped downward extension skin flap is turned upside down, it can be completely overlapped with the dumbbell-shaped upward extension skin flap by rotating 90 degrees along its central axis; The surface of the extensor flap is the same color. The air valve of the soft ball is located at the center of the dumbbell-shaped downward stretching skin flap or the dumbbell-shaped upward stretching skin flap.

Embodiment 2

[0018] Embodiment 2, the aerodynamically optimized soft ball of the present invention is a soft ball with air valves and built-in sand grains. The surface of the soft ball is formed with a curved dumbbell ring groove, and the dumbbell ring groove will The surface of the force ball is divided into a dumbbell-shaped downward-extending flap and a dumbbell-shaped upward-extending flap that are equally butted up and down. The above and below being equal means that the dumbbell-shaped downward-extending skin flap is turned upside down or rotated 180 degrees around the circle where its arc-shaped central axis is located, and then rotated 90 degrees along its central axis to completely overlap with the dumbbell-shaped upward-extending skin flap; The surface color of the dumbbell-shaped downward stretching flap is different from that of the dumbbell-shaped upward stretching flap. The air valve of the soft ball is located at the center of the dumbbell-shaped downward stretching skin fla...

Embodiment 3

[0019] Embodiment 3, the difference between the aerodynamically optimized soft ball of the present invention and the second embodiment is that the soft ball is a light-colored dumbbell-shaped downward-extending skin flap made of light-colored elastic plastic material and a light-colored valve inward. The base layer of the light-colored dumbbell-shaped upward extension skin flap and the light-colored curved dumbbell-shaped ring-shaped groove are composed of a soft ball base. The outer surface of the base layer of the light-colored dumbbell-shaped upward extension skin flap is compounded with a dark dumbbell-shaped upward extension skin flap. outer layer. The protrusions are clustered protrusions distributed at even intervals.

Abstract

The invention relates to an aerodynamics optimized softball, in order to solve the problem of an existing softball which is poor in aerodynamic performance; the softball comprises a valve and a softball which contains sand grains therein; the softball is characterized in that an arched dumbbell ring shaped groove is formed in the surface of the softball, wherein by virtue of the dumbbell ring shaped groove, and the surface of the softball is divided into a dumbbell shaped downward extension flap and a dumbbell shaped upward extension flap which are abutted in a mode of being equal up and down. On the surfaces of the dumbbell shaped downward extension flap and the dumbbell shaped upward extension flap, the softball is formed with bumps or pits which are uniformly distributed. The arched dumbbell ring shaped groove is an independent groove which has an arc-shaped cross section or the groove is composed of two or three sub-grooves which are arranged side by side. The softball disclosed by the invention has advantages of guiding airflow and optimizing aerodynamics by virtue of the arched dumbbell ring shaped groove.

Description

technical field [0001] The invention relates to a softball, in particular to an aerodynamically optimized softball. Background technique [0002] The differences between softball and other traditional balls are as follows: 1. The surface of the racket is soft, and it is used to catch the ball with a cut surface and hit the ball with a cut surface to serve. 2. The ball is under-inflated, and its elasticity is much smaller than that of traditional balls, so the ball will inevitably deform significantly when being hit and running. 3. A certain amount of free sand is placed in the ball. The addition of sand makes the center of gravity of the ball not located at the center of the ball like the traditional ball. The ball will shift the center of gravity due to the flow of sand during the movement. However, although the soft ball has the above-mentioned many differences with the traditional ball, its outer surface in contact with the air still follows the traditional ball. [000...
