Sphere structure

Abstract

A spherical structure includes: a central portion; a spherical surface extending along a spherical surface and covering a portion of the surface of the central portion; and a plurality of planar portions, each planar portion being a plane, the planar portions adjacent to each other covering the remaining surface of the central portion, and each adjacent planar portion being separated by the spherical surface. The planar portions prevent the spherical structure from rolling, and even if it does roll, it may not be directional, thus helping to train the reaction speed of the elderly and young children. The spherical surface portions assist the spherical structure in rolling, effectively training the physical strength of the elderly and young children and achieving exercise effects.

Description

Technical Field

[0001] This invention relates to a spherical structure. Prior Technology

[0002] When older adults play ball games, the ball tends to roll too far, excessively consuming their physical strength and reducing their enjoyment and willingness to exercise.

[0003] To reduce the rolling distance of balls, the following patents propose different ball structures:

[0004] Republic of China Patent Publication No. M444859 discloses a polyhedral sphere whose main body is composed of several convex polygonal buffer bodies connected at their vertices, and the penetrating surfaces formed by the edges of the connected buffer bodies constitute the polyhedral sphere. Due to the design of these penetrating surfaces, users can easily pass their fingers through to grasp the main body of the polyhedral sphere. Furthermore, the polyhedral main body is not prone to rolling, and the buffer bodies have low bounce characteristics, making it suitable for rehabilitation and children's play and practice.

[0005] Chinese Patent Publication No. CN 114904236 A discloses a cube-shaped soccer ball suitable for middle-aged and elderly people. It includes a first fabric, a second fabric, a third fabric, a fourth fabric, a fifth fabric, and a sixth fabric, as well as air holes on the fifth fabric. The first, second, third, and fourth fabrics are sequentially bonded together. The fifth fabric is positioned above the first, second, third, and fourth fabrics, and its four sides are bonded to the first, second, third, and fourth fabrics respectively. The sixth fabric is positioned below the first, second, third, and fourth fabrics. This cube-shaped soccer ball design minimizes the possibility of people being unable to catch the ball, avoids limitations imposed by playing field conditions, improves its applicability, and ensures that middle-aged and elderly people can receive adequate exercise and improve their physical fitness.

[0006] Chinese Patent Publication No. CN 115006805 A discloses an abacus-shaped soccer ball suitable for middle-aged and elderly people. The ball includes a bottom fabric, a top fabric, a first side fabric, a second side fabric, and a connecting fabric. The bottom fabric is bonded to the first side fabric, the first side fabric is bonded to one end of the connecting fabric, the other end of the connecting fabric is bonded to the second side fabric, and the top fabric is bonded to the end of the second side fabric away from the connecting fabric. The top fabric has air inlets. This abacus-shaped soccer ball reduces its rolling distance, allowing middle-aged and elderly people to better contact the ball and avoid situations where they cannot keep up with the ball. It enhances the fun and improves fitness, and because the rolling distance is reduced, it can be used in a space without a large area, increasing its applicability.

[0007] However, these patents excessively reduce the rolling distance of the balls, and the balls in these patents may not even roll at all, so the elderly hardly need to run or walk, and cannot achieve a certain amount of exercise for the elderly. Summary of the Invention

[0008] Therefore, the inventors propose a spherical structure comprising: a central portion; a spherical surface extending along a spherical surface and covering a portion of the surface of the central portion; and a plurality of planar portions, each planar portion being a plane, the planar portions covering the remaining surface of the central portion adjacent to each other, and the spherical surface being spaced between adjacent planar portions.

[0009] The central part is a hollow sphere.

[0010] The central part is a solid sphere.

[0011] The central part, the spherical part, and the planar part are made using foam molding technology or plastic injection molding technology.

[0012] The central part, the spherical part, and the planar part are integrally formed.

[0013] In forming the spherical surface, the planar portion is formed by using a mold to constrain a portion of the spherical surface.

[0014] In this process, after the spherical surface is formed, a portion of the spherical surface is removed using a tool to form the planar portion.

[0015] Wherein, all the planar parts are circular planes, the radius of each planar part is between 10% and 30% of the radius of the sphere, the number of the planar parts is between 3 and 20, and the total area of ​​the planar parts is between 5% and 50% of the surface area of ​​the sphere.

[0016] Based on the above technical features, the following effects can be preferably achieved:

[0017] 1. The flat surface makes the sphere less prone to rolling, and even if it does roll, it may not be directional, which can help train the reaction ability of the elderly and young children.

[0018] 2. The spherical surface assists in the rolling of the sphere, which can effectively train the physical strength of the elderly and young children and achieve exercise effects.

[0019] 3. Depending on the user's physical strength and movement needs, different radii and numbers of spheres can be selected to achieve different degrees of rolling.

[0020] 4. Depending on the user's physical strength and exercise needs, a hollow or solid center can be selected to change the weight of the sphere's structure. Simple Explanation of the Diagram

[0028] Based on the above technical features, the main functions of the spherical structure of the present invention will be clearly demonstrated in the following embodiments.

[0029] Please refer to Figures 1 to 3, which illustrate the spherical structure of an embodiment of the present invention, comprising:

[0030] A central part 1, 1a, the central part 1 can be a solid sphere as shown in the second figure, and in another embodiment, the central part 1a can also be a hollow sphere as shown in the third figure.

[0031] However, only the central part 1 will be described below, and the other structures in the third figure are also represented by the same element symbols as in the second figure.

[0032] A spherical surface 2 extends along a spherical surface and covers a portion of the surface of the central portion 1. The spherical surface can be regarded as the surface of the central portion 1 or the surface of an imaginary sphere formed by the outward expansion of the central portion 1.

[0033] A plurality of planar portions 3, each of which is a circular plane, are adjacent to each other and cover the remaining surface of the central portion 1, and each adjacent planar portion 3 is separated by a spherical surface 2.

[0034] The radius of each planar portion 3 is between 10% and 30% of the radius of the sphere, the number of planar portions 3 is between 3 and 20, and by selecting and combining these two values, the total area of ​​the planar portions 3 is between 5% and 50% of the surface area of ​​the sphere.

[0035] In a preferred embodiment of the present invention, the central portion 1, the spherical portion 2, and the planar portion 3 are integrally formed and are manufactured using foam molding technology or plastic injection molding technology.

[0036] The planar portion 3 can be formed by using a mold to constrain a portion of the spherical portion 2 during the formation of the spherical portion 2. Specifically, the interior of the mold can be generally spherical and have a partially protruding plane to form the spherical portion 2 and the planar portion 3, respectively.

[0037] Alternatively, after forming the spherical part 2, a portion of the spherical part 2 can be removed with a tool, such as a cutting machine, to form the planar part 3.

[0038] Please refer to Figures 4 and 5. In actual implementation of this spherical structure, depending on its size (e.g., the size of a basketball or ping-pong ball), users, such as the elderly, can directly throw, catch, or kick the spherical structure, or strike it with an appropriate racket for exercise and rehabilitation training. This invention does not limit the method of using this spherical structure.

[0039] During exercise and rehabilitation training, the spherical structure may roll on a ground surface A.

[0040] When the ball surface 2 contacts the ground A, the ball surface 2 will assist the ball structure to roll, which can effectively train the user's physical strength and achieve exercise effect.

[0041] Please refer to Figures 6 and 7. When the spherical structure continues to roll and the flat part 3 contacts the ground A, the flat part 3 makes the spherical structure less likely to roll.

[0042] Even if the spherical structure continues to roll, it may roll in an unpredictable direction due to the different contact angles between the flat part 3 and the ground A. Users need to clearly see the rolling direction of the spherical structure before chasing it, which can train the user's reaction ability.

[0043] Taking young children as an example, the flat part 3 slows down the rolling speed of the spherical structure, making it easier for young children to grasp and control the spherical structure. This can maintain the children's willingness to continue using the spherical structure, making them more willing to explore and touch the spherical structure, thereby improving the effectiveness of children's activities and training.

[0044] Please refer to Figures 2 and 3. Depending on the physical strength and exercise needs of different users, the hollow or solid central part 1, 1a can be selected to change the weight of the sphere structure. Different radii and numbers of the planar parts 3 can also be selected to achieve different degrees of rolling.

[0045] For example, the spherical structure with a larger radius and more of the planar part 3 may have a shorter rolling distance, making it more suitable for users with poor physical strength. However, users whose physical strength has improved after a period of training can switch to the spherical structure with a smaller radius and fewer of the planar part 3. This gradual training can more effectively help users gradually improve their physical strength.

[0046] Based on the above description of the embodiments, one can fully understand the operation, use and effects of the present invention. However, the above embodiments are only preferred embodiments of the present invention and should not be used to limit the scope of the present invention. Simple equivalent changes and modifications made in accordance with the scope of the patent application and the description of the invention are all within the scope of the present invention.
