Description

Technical Field

[0001] The present invention relates to a ball intercepting device and supporting court equipment. Background Art

[0002] At present, ball fitness exercises are deeply loved by people, such as table tennis and football. For ordinary people, most ball games are exercises for the upper body, such as table tennis, badminton, tennis, and volleyball. There are few ball games that exercise the lower body, mainly football, but football has many rules and high requirements for the number of people and the venue. To facilitate the promotion of national fitness exercises, it is necessary to design a national fitness exercise that exercises the lower body, has variable exercise amounts, few venue restrictions, and is convenient for practicing anytime and anywhere. Summary of the Invention

[0003] The present invention provides a ball intercepting device and supporting court equipment that have low requirements for the venue and mainly exercise the lower body to solve the deficiencies of the prior art.

[0004] To achieve the above technical objectives, the present invention adopts the following implementation schemes.

[0005] A ball intercepting device includes a spherical body with a smooth bottom surface or / and top surface, which is cylindrical or disc-shaped. The side surface of the spherical body is made of an elastic material, and a counterweight with the same center of gravity as the spherical body is fixed inside the spherical body.

[0006] In this embodiment, the spherical body is integrally formed with a hard elastic material.

[0007] In this embodiment, the bottom surface or / and top surface of the spherical body is a plane.

[0008] In this embodiment, a plurality of wear-resistant blocks are symmetrically fixed on the bottom surface or / and top surface of the spherical body with the central axis as the center, and the wear-resistant blocks protrude 1 mm to 5 mm from the bottom surface of the spherical body.

[0009] In this embodiment, the side surface of the spherical body is wrapped with a shell made of an elastic material, and the shell is preferably made of a metal elastic material.

[0010] In this embodiment, the height of the spherical body is 1.5 cm to 4.5 cm.

[0011] In this embodiment, the diameter of the spherical body is 5 cm to 20 cm.

[0012] In the above embodiment, through the combination of the diameter, height, and configuration of the spherical body, three preferred schemes of small, medium, and large spherical bodies are formed. The diameter of the small spherical body is 7 cm, the height is 2 cm, and the weight is 50 - 75 grams. The diameter of the medium spherical body is 9 cm, the height is 2.5 cm, and the weight is 75 - 110 grams. The diameter of the large spherical body is 20 cm, the height is 5 cm, and the weight is 110 - 200 grams.

[0013] A stadium equipment matching with a intercepting ball, including a main field, a rebound board is fixed on the main field, the side of the rebound board in contact with the intercepting ball is made of an elastic material, and the main field is a smooth plane.

[0014] In this embodiment, the main field is rectangular, and two rebound boards are fixedly arranged in parallel on the opposite side edges of the main field.

[0015] In this embodiment, two parallel rebound boards or two goalposts can be selectively fixed on the other opposite side edges of the main field respectively.

[0016] In this embodiment, the top of the rebound board protrudes inward towards the main field to form an edge, and the gap between the top edge of the rebound board and the main field is greater than the height of the intercepting ball.

[0017] The bottom surface of the intercepting ball of the present invention is flat and hollow inside, so that the intercepting ball has good adhesion to the ground and is not easily kicked away. When playing football, kick the side of the intercepting ball, so that the intercepting ball slides on the ground, and the hard elastic material on the side of the intercepting ball impacts the wall or other hard materials to achieve rebound, thereby increasing the fun of playing football, so that people can get exercise unconsciously in the game; moreover, people can participate in this game on the stadium equipment matching with the intercepting ball, so the fun is higher. Since the main field is a smooth ground, the intercepting ball slides farther, and when the intercepting ball impacts on the rebound board, the movement direction can be changed. By adding facilities such as goalposts on both sides of the main field, the fun of the game can be increased through defense and offense, and the exercise effect can be improved. Of course, with the establishment of various playing methods of the intercepting ball, the intercepting ball can also be used as a competitive sport like football and basketball.

[0018] Due to the adoption of the above technical solutions, the present invention achieves the effect of fitness in entertainment. On the one hand, it can be used as a competitive sport for teenagers to improve the reaction ability. On the other hand, it is also suitable for the game entertainment and fitness of men, women, the elderly and children. The present invention can select balls of different sizes according to the levels of different sports enthusiasts, and the sports threshold is low. The elderly can choose larger balls for entertainment and fitness. Larger balls are easier to see clearly and the movement speed is slower. Women who don't exercise much in daily life can also use medium-sized balls for entertainment and fitness activities. Energetic young people can use smaller balls for competitions. The present invention has many characteristics of table tennis and football, and there are various playing methods. For example, it can be similar to the playing method of table tennis. One side kicks the ball towards the rebound board on the stadium, and the ball changes direction through the rebound board and then moves to the other side's field, and is caught by the athletes on the other side's field. There are many offensive and defensive changes, many rounds of the incoming ball, the amount of exercise can be large or small, and at the same time, it has the pleasure of football shooting. It is a brand-new sport integrating the characteristics of games and fitness. Description of the Drawings

[0026] In order to better understand the present invention, the following further details the invention in conjunction with the accompanying drawings and implementation examples. However, the implementation manners of the present invention are not limited to this, and the protection scope of the present invention also covers equivalent technical means that can be conceived by those skilled in the art according to the concept of the present invention.

[0027] See Figure 1 、 Figure 2, a kind of intercepting ball. The intercepting ball in this embodiment belongs to a ground - sliding ball, including a sphere 1 with smooth bottom and top surfaces, which is cylindrical or disc - shaped. The sphere is integrally formed by a hard elastic material. In this embodiment, the hard elastic material is celluloid. A counterweight with the same center of gravity as the sphere is fixed inside the sphere. The sphere 1 includes an upper outer shell 11 and a lower outer shell 15 fixedly connected. An upper inner shell 12 is also provided inside the upper outer shell 11, and a lower inner shell 14 corresponding to the upper inner shell 12 is fixed inside the lower outer shell 15. After the upper outer shell 11 and the lower outer shell 15 are fixed, the upper inner shell 12 and the lower inner shell 14 are also correspondingly fixed. A cavity is provided between the fixed upper inner shell 12 and the lower inner shell 14, and a counterweight 3 is fixed in the cavity. The counterweight has the same center of gravity as the sphere, and the weight of the counterweight is greater than the weight of the sphere. The counterweight 3 is a solid cylinder with a diameter of 1 - 3 cm and a height of 1 - 4 cm, made of a heavier metal or similar material, so that the intercepting ball has high stability and is not prone to tipping over during impact. The inside of the sphere 1 can be hollow, and wear - resistant blocks can be inlaid on the bottom surface and / or the side surface, thereby increasing the smoothness of the bottom surface and the elasticity of the side surface, making the intercepting ball slide more smoothly on the home court and having a better rebound effect after being impacted.

[0028] The upper outer shell 11 and the lower outer shell 15 are made of plastic materials of high - molecular polymers, or celluloid, or metal materials, etc., ensuring that the intercepting ball only undergoes elastic deformation and does not break under the maximum external force applied by a person under normal circumstances. And the elasticity of the intercepting ball enables the ball to reach the requirements of the game or entertainment in terms of sliding speed. For example, during the movement process, the speed can reach 100 km / h, and in the case of rebound, the speed after rebound is not less than 50 km / h, and the rebound distance is not less than 20 m. As another implementation mode of the intercepting ball, a plurality of wear - resistant blocks are symmetrically fixed on the bottom surface of the upper outer shell 11 and the lower outer shell 15 of the intercepting ball with the central axis as the center, making the side of the ball have greater elasticity and the bottom surface be relatively smooth so that it can continuously slide on the ground. The wear - resistant blocks protrude 1 mm - 5 mm from the bottom surface of the sphere.

[0029] In this embodiment, the diameter of the sphere composed of the upper outer shell 11 and the lower outer shell 15 is 5 - 20 cm, and the height is 1 - 4 cm. The upper inner shell 12 and the lower inner shell 14 are inner - hollow cylinders with a diameter of 1 - 3 cm and a height of 1 - 2 cm.

[0030] Example 1:

[0031] Such as Figure 3 、 4As shown in the figure, a stadium equipment that matches the intercepted ball includes a main field 3. A rebound board 2 is fixed on the main field 3. The rebound board 2 is made of a hard elastic material. The main field is a smooth plane and is rectangular. Two rebound boards 2 are fixedly parallel to the opposite side edges of the main field. The gap between the top edge of the rebound board and the main field is greater than the height of the intercepted ball. The material used for the main field is wood, plastic, metal or composite material. In this embodiment, by selecting the materials of the main field and the intercepted ball, the friction coefficient between the intercepted ball and the main field is ensured to be <0.6. At this time, the sliding of the intercepted ball on the main field better meets the sports requirements.

[0032] As Figure 2 shown in the figure, the rebound board 2 can not only be a straight board, but also an inverted L shape with the top protruding towards the inner side of the main field to form an edge. The rebound board 2 has a certain elasticity. The material for making the rebound board 2 can be composite material, wood or high-end SMC material. The elasticity of the material of the rebound board 2 can make the speed of the intercepted ball after rebounding reach a basic 50 kilometers per hour. In this way, the speed is faster and the entertainment value is higher. When in use, the rebound board 2 is fixed on the ground with screws, and the rebound board 2 can also be built on the ground with materials such as cement and marble.

[0033] In this embodiment, the main field 4 is arranged inside the outer field 5. The outer field 5 can be made into a fence with a baffle 20 - 35 cm high to form a sports field, preventing the intercepted ball from sliding too far, and the material of the outer field 5 is the same as that of the main field 3.

[0034] As Figure 3 shown in the figure, in this embodiment, inside the outer field 5, a main field 4 is formed by enclosing it with a 2 - centimeter-wide white line. The long side of the main field 4 is called the rebound line, and the rebound board is installed at the rebound line. The short side is called the baseline 6. A center line parallel to the baseline 6 is provided at the center of the connection of the two baselines 6 of the main field 4. The center line divides the main field into two left and right rebound semi-areas. During the game, two groups of players stand on the corresponding outer fields 5 of the two rebound semi-areas respectively. The intercepted ball is inside the main field 4. At this time, a cuboid rebound board or a goal can be set at the baseline 6 (the gameplay can be similar to football). One group of players kicks the intercepted ball with their feet, kicks the intercepted ball across the center line and into the opponent's rebound semi-area, and then the opponent catches the ball and kicks it back. The kick can be a direct kick or a kick after rebounding through the rebound board across the center line. This process is repeated, thus achieving the effects of entertainment and fitness. Of course, this device can also be used as a competitive event. Two teams compete, setting a time limit or determining a specific score. After the ball crosses the baseline 6, if one side catches the opponent's ball, then this side attacks. If the opponent's ball is not caught, then the opponent scores. After the final time ends, the winning side is determined by the higher score or the side that reaches the established score first is the winning side.

[0035] As an implementation manner of this embodiment, this device can be used for multi-person sports or for single-person or two-person sports. When used for single-person or two-person sports, the total size of the court is 7×14 meters, and a main court is set in the court, and the size of the main court is (1.5 - 3) meters × (3 - 8) meters.

[0036] Embodiment 2:

[0037] Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that two ball nets 8 are respectively fixed at the other two opposite bottom lines of the main court 7, thereby improving the entertainment of the game. When two teams play a game, the score can be obtained by the ball entering the opponent's ball net.

[0038] As an implementation manner of this embodiment, when the court is used as a court for multi-person sports, the size of the court can be set to 45×60 meters.

[0039] The above embodiments are only used to exemplarily illustrate the principle and its effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
