Description

Technical Field

[0001] This utility model relates to the field of Tai Chi balls, specifically to an elastic, strikeable honeycomb Tai Chi ball. Background Technology

[0002] A search revealed several existing Tai Chi balls. For example, Chinese patent document CN201304217Y discloses a Tai Chi ball composed of a spherical outer skin and a spherical inner bladder within the outer skin. A cavity exists between the outer skin and the inner bladder, and an air inlet is provided at the junction of the inner bladder and the outer skin. The outer skin also has cavity air inlets. This Tai Chi ball addresses the current problem of limited exercise options for the elderly and the lack of suitable exercise equipment. It can be used to strike the Tai Chi ball with a badminton racket or tennis racket.

[0003] Chinese patent document CN205287469U discloses an inflatable Tai Chi ball, comprising an outer sphere, an inner sphere, a spring, and a core sphere. The inner sphere is located inside the outer sphere. An inflation nozzle is provided on the surface of the outer sphere. The outer sphere consists of an inflatable capsule. The inner sphere is one or more hollow spheres, and a core sphere is located inside the inner sphere. The core sphere is attached to a spring, one end of which is connected to the core sphere, and the other end is fixed to the inner wall of the inner sphere. This Tai Chi ball, with the addition of a core sphere and electronic devices, increases the product's appeal and broadens its applicability, making it a healthy product for exercise, games, fitness, health maintenance, and physiotherapy.

[0004] Chinese patent document CN104689529A discloses a fitness Tai Chi ball with a magnetic therapy layer, comprising a sphere, the sphere being a solid wooden sphere. From the inside out, the outer surface of the solid wooden sphere is provided with a protective layer, a magnetic therapy layer, a wear-resistant layer, and a coating layer. The protective layer is made of an elastic material, and the magnetic therapy layer comprises a plurality of tightly arranged magnetic beads. This invention provides a magnetic therapy layer on the outer surface of the solid wooden sphere, achieving a magnetic therapy effect; a protective layer is provided between the magnetic therapy layer and the solid wooden sphere to prevent impact damage to the solid wooden sphere from the magnetic therapy layer; the wear-resistant layer can be used to cover the magnetic therapy layer.

[0005] Analysis reveals that a key characteristic of currently disclosed Tai Chi balls is their sealed outer surface, including but not limited to those disclosed in CN201304217Y, CN205287469U, and CN104689529A. These sealed Tai Chi balls produce a louder sound when struck, and most require inflation, such as CN201304217Y and CN205287469U. While CN104689529A does not require inflation, its solid wooden sphere is relatively heavy, and it is not intended for striking and lacks elasticity. Summary of the Invention

[0006] In view of this, in order to solve the above-mentioned technical problems, the purpose of this utility model is to propose an elastic, strikeable honeycomb tai chi ball with a non-enclosed, breathable surface that produces a relatively low sound when struck.

[0007] The technical solution adopted is as follows:

[0008] A flexible, strikeable honeycomb tai chi ball is composed of two or more layers of spherical surfaces made of elastic material. Each layer has multiple continuous hexagonal holes forming a honeycomb pattern. All spherical surfaces share a common center and are nested layer by layer from the inside out. The diameter of all spherical surfaces increases proportionally from the innermost to the outermost layer, and the hexagonal holes also increase proportionally from the inside out. Adjacent spherical surfaces are connected by columnar members, and the innermost spherical surface has a cavity. Each spherical surface is painted with one color in one half and another color in the other half, forming a tai chi ball with a tai chi pattern distribution.

[0009] Furthermore, the number of spherical layers is 2-10.

[0010] The number of spherical layers is further preferably 2-4.

[0011] Furthermore, the diameter of the outermost spherical surface of the Tai Chi ball is 73±3mm.

[0012] Furthermore, the elastic material is TPU or PEBA.

[0013] Furthermore, all spherical and cylindrical parts are integrally formed using 3D printing.

[0014] The beneficial effects of this utility model are as follows:

[0015] On the one hand, because the Tai Chi ball is composed of two or more layers of spherical surfaces made of elastic material, each layer has multiple continuous hexagonal holes forming a honeycomb-like surface. All the spherical surfaces have the same center, and all the spherical surfaces are nested one on top of the other with intervals from the inside out. The diameter of all the spherical surfaces increases proportionally from the innermost layer to the outermost layer, and the hexagonal holes of all the spherical surfaces also increase proportionally from the inside out. Adjacent spherical surfaces are connected by columnar members, and the innermost spherical surface has a cavity. In this way, not only is a stable honeycomb spherical structure formed, with adjacent spherical surfaces supporting each other from the inside out through columnar members, but all the spherical surfaces from the inside out are also breathable through their respective regular hexagonal holes. This gives the honeycomb spherical structure a non-closed, breathable surface, resulting in a quieter sound when struck, making it suitable for fitness.

[0016] On the other hand, since all the spheres are sprayed with one color in one half and another color in the other half, forming a Tai Chi sphere with Tai Chi pattern distribution characteristics, the Tai Chi sphere can not only be used for fitness, but also has the aesthetic appeal of inner and outer Tai Chi pattern characteristics. The inner sphere can be observed through the hexagonal holes, so that a three-dimensional, multi-layered Tai Chi pattern can be viewed. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0028] See Figures 1-2 As shown, a flexible, strikeable honeycomb tai chi ball is composed of two or more layers of spherical surfaces 10 made of elastic material. Each layer of spherical surface 10 has multiple continuous hexagonal holes 20 forming a honeycomb spherical surface. All spherical surfaces have the same center. All spherical surfaces are nested one on top of the other with intervals from the inside out. The diameter of all spherical surfaces increases proportionally from the innermost spherical surface 11 to the outermost spherical surface 12. The hexagonal holes 20 of all spherical surfaces also increase proportionally from the inside out. Adjacent spherical surfaces are connected by columnar members 13. The innermost spherical surface has a cavity. All spherical surfaces are sprayed with one color in one half and another color in the other half, forming a tai chi ball with a tai chi pattern distribution.

[0029] Generally, the more spherical layers there are, the smaller the cavity of the innermost spherical layer 11. The number of spherical layers can be, for example, 2-10 layers, depending on actual needs, with 2-4 layers being the optimal configuration. This embodiment uses 2 spherical layers.

[0030] The two colors used for spraying can be black and white, or yellow and white, or orange and white, depending on the actual needs.

[0031] In one specific implementation, the diameter of the outermost spherical surface of the Tai Chi ball can be 73±3mm; the weight can generally be 31±5g.

[0032] As one specific implementation, the elastic material includes, but is not limited to, TPU or PEBA. Any known elastic material that can be used for 3D printing in the prior art is acceptable. For example, TPU or PEBA are known elastic materials that are commercially available and can be used as 3D printing elastic materials. TPU is thermoplastic polyurethane, a mature and widely used 3D printing elastic material in the prior art. PEBA is polyether block amide, a high-performance thermoplastic elastomer in the prior art, composed of flexible polyether segments and rigid polyamide block copolymers.

[0033] In one specific implementation, all spherical and cylindrical components are integrally formed using 3D printing. That is, all spherical and cylindrical components are manufactured from the same material using 3D printing. The connection between the spherical and cylindrical components is an integral molding connection.

[0034] The cross-sectional shape of the columnar components is not limited; it can be circular, square, hexagonal, or other shapes, depending on the actual needs. The number of columnar components between any two adjacent spherical surfaces can be multiple, with the specific number chosen based on the stability of the structure. Ideally, multiple columnar components should be evenly distributed.

[0035] Taking the Tai Chi ball with two spherical surfaces in this embodiment as an example, the preparation method of this elastic, strikeable honeycomb Tai Chi ball includes the following steps:

[0036] First, the innermost spherical layer is 3D printed, then the columnar part is 3D printed, and finally the outermost spherical layer is printed. The 3D printing proceeds sequentially from the inside out. Each layer of spherical surface has multiple continuous hexagonal holes forming a honeycomb structure. All spherical surfaces share a common center, and they are nested layer by layer with intervals from the inside out. The diameter of all spherical surfaces increases proportionally from the innermost to the outermost layer, and the hexagonal holes in all spherical surfaces also increase proportionally from the inside out.

[0037] In this way, on the one hand, the honeycomb sphere structure with hexagonal holes is itself a relatively stable structure. Adjacent spheres are connected by columnar members, thus supporting each other and forming a stable structure. On the other hand, all spheres from the inside out are interconnected through their respective regular hexagonal holes, giving the honeycomb sphere structure a non-closed, breathable surface, resulting in a quieter sound when struck. This is because with traditional, non-breathable balls, air is compressed upon impact, creating a brief period of high pressure, similar to the vibration of a drumhead, producing resonance that amplifies the sound. However, with this breathable tai chi ball, air flows through the hexagonal holes, reducing the compression effect, suppressing resonance, and resulting in a quieter sound.

[0038] In summary, this Tai Chi ball is quiet, elastic, small in size (diameter can be 73±3mm), and lightweight (weight can generally be 31±5g). It does not require high skill or physical strength and can be used as a fitness ball for a wide range of people. It can be used for singles or doubles fitness by two people or four people.

[0039] Furthermore, because this Tai Chi ball is elastic and small in size, holding it with one hand can exercise hand muscles and relieve stress, giving it a certain stress-relieving function.

[0040] On the other hand, see Figure 3The divided areas are painted with one color in one half of the sphere 31 and another color in the other half sphere 32, forming a Tai Chi ball with a Tai Chi pattern distribution. Thus, the Tai Chi ball can not only be used for fitness, but also has the aesthetic appeal of inner and outer Tai Chi pattern features. The inner sphere can be observed through the hexagonal holes, so a three-dimensional, multi-layered Tai Chi pattern can be viewed.

[0041] The colors can be sprayed as needed, thus creating Tai Chi balls with various color combinations. Example 2

[0042] See Example 1. Unlike Example 1, the Tai Chi sphere in this example has three spherical layers. Figure 4 As shown.

[0043] During fabrication, the innermost spherical surface 11 is 3D printed first, followed by the columnar component 13 of the first layer, then the spherical surface 14 of the middle layer, then the columnar component 13 of the second layer, and finally the outermost spherical surface 12. The 3D printing proceeds sequentially from the inside out. Each layer of spherical surface has multiple continuous hexagonal holes forming a honeycomb structure. All spherical surfaces share a common center, and they are nested layer by layer from the inside out with intervals. The diameter of all spherical surfaces increases proportionally from the innermost to the outermost layer, and the hexagonal holes in all spherical surfaces also increase proportionally from the inside out. Example 3

[0044] See Example 1. Unlike Example 1, the Tai Chi ball in this example has four spherical layers. Figure 5 As shown.

[0045] During fabrication, the innermost spherical surface 11 is 3D printed first, followed by the columnar component 13 of the first layer, then the spherical surface 15 of the first intermediate layer, then the columnar component 13 of the second layer, then the spherical surface 16 of the second intermediate layer, then the columnar component 13 of the third layer, and finally the outermost spherical surface 12. The 3D printing proceeds sequentially from the inside out. Each layer of spherical surface has multiple continuous hexagonal holes forming a honeycomb structure. All spherical surfaces share a common center, and they are nested layer by layer from the inside out with intervals. The diameter of all spherical surfaces increases proportionally from the innermost to the outermost layer, and the hexagonal holes in all spherical surfaces also increase proportionally from the inside out.

[0046] It should be noted that the distinction between the spherical surface of the intermediate layer, the spherical surface of the first intermediate layer, and the spherical surface of the second intermediate layer is made for different embodiments and is only for ease of description and understanding. It should be understood based on the description of the embodiments.

[0047] The detailed descriptions listed above are merely specific descriptions of feasible embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. All equivalent embodiments or modifications made without departing from the spirit of the present utility model should be included within the scope of protection of the present utility model.
