Definitions

  • the present invention relates to a paddle racket.
  • a racket includes a striking portion and a handle.
  • the striking portion includes a frame body and a striking member (such as a plate, net wire or the like) disposed with the frame body. If the striking member is of considerable thickness and solid structure, it requires a large amount of raw materials (plastic, wood, metal, etc.) for producing the racket, which increases the production cost and causes a heavy weight of the racket unfavorable for play.
  • the present invention is, therefore, arisen to obviate or at least mitigate the above-mentioned disadvantages.
  • the main object of the present invention is to provide a paddle racket which has sufficient structural strength and light weight so that it the paddle racket can be operated swiftly.
  • a paddle racket including: a frame body, including a frame wall and a handle connected with the frame wall, the frame wall defining a receiving space; a three-dimensional web core, disposed in the receiving space and circumferentially connected to the frame wall, including a plurality of channels disposed through the three-dimensional web core in a thickness direction of the three-dimensional web core; and two striking surface portions, disposed on two opposing sides of the three-dimensional web core and connected to the frame wall, each of the two striking surface portions including a plurality of through holes, the plurality of through holes corresponding to and being in communication with the plurality of channels.
  • a paddle racket 1 of the present invention includes a frame body 10, a three-dimensional web core 20 and two striking surface portions 30.
  • the frame body 10 includes a frame wall 11 and a handle 12 connected with the frame wall 11, and the frame wall 11 defines a receiving space 13;
  • the three-dimensional web core 20 is disposed in the receiving space 13 and circumferentially connected to the frame wall 11, and the three-dimensional web core 20 includes a plurality of channels 21 (may extend linearly, or may be defined by frames of the three-dimensional web core 20 and extend non-linearly) disposed through the three-dimensional web core 20 in a thickness direction of the three-dimensional web core 20;
  • the two striking surface portions 30 is disposed on two opposing sides of the three-dimensional web core 20 and connected to the frame wall 11, each of the two striking surface portions 30 includes a plurality of through holes 31, the plurality of through holes 31 correspond to and are in communication with the plurality of channels 21.
  • the three-dimensional web core 20 has sufficient structural strength and light weight so that the paddle racket 1 can be operated swiftly.
  • an inner side surface of the frame wall 11 is radially concave
  • an outer circumferential surface of the three-dimensional web core 20 is radially convex and connected with the inner side surface of the frame wall 11 which is radially concave, so that the three-dimensional web core 20 can be firmly connected to the frame wall 11.
  • the inner side surface of the frame wall 11 and the outer circumferential surface of the three-dimensional web core 20 may be flat surfaces.
  • the outer circumferential surface of the three-dimensional web core 20 is continuously annular and enclosed, which increases connection area and combination with the frame wall 11.
  • the frame body 10 is a reinforced fiber member
  • the three-dimensional web core 20 further includes two side layers 22 which are opposite to each other and a framework 23 which is integrally connected with and between the two side layers 22.
  • the two striking surface portions 30 are reinforced fiber members and coated on the two side layers 22, respectively.
  • Reinforced fiber such as glass fiber, carbon fiber or the like, is of properties of light weight and strong structure. With the two side layers 22, the two striking surface portions 30 can be made to be more flat.
  • the two side layers 22 may be made from fiber cloths pre-impregnated and coated on the two striking surface portions 30 after curing.
  • Each of the two side layers 22 includes a plurality of openings 221
  • the framework 23 includes a plurality of communication holes 231
  • the plurality of communication holes 231 correspond to and are in communication with the plurality of openings 221 of each of the two side layers 22, so that the resistance due to air during operation of the paddle racket is reduced.
  • the three-dimensional web core 20 and the two striking surface portions 30 may be made from the same material and integrally formed of one piece, and thus it is easy to manufacture.
  • the three-dimensional web core 20 is made from light hardening resin (UV light hardening resin), which provides good support and sufficient elastic deformability.
  • Light hardening resin is hardened by light projecting on predetermined regions, which is easy and quick to manufacture.
  • the light-hardening resin is contained in a container with a transparent bottom side; a platform is immersed into the light hardening resin in the container and close to the bottom side of the container; according to patterns of various cross-sections of the three-dimensional web core 20 the light is projected onto and hardens parts of the light hardening resin on the platform to form a part of the three-dimensional web core 20.
  • the platform is moved away from the bottom side of the container step by step, and finally the three-dimensional web core 20 is grown.
  • the manufacturing process is simple, fast and of lower manufacturing cost.
  • the three-dimensional web core 20 may be formed by using any of other forms of 3D printing technology.
  • the three-dimensional web core 20 further includes a first portion 24 and a second portion 25 which is farther from the handle than the first portion the handle 12, and the second portion 25 has a density per unit volume greater than a density per unit volume of the first portion 24.
  • the second portion 25 has better structural strength and swing inertia near the sweet center (near the second portion 25) of the paddle racket 1, which improves the swing effect and increases durability.
  • the frame wall 11 further includes a partition portion 111, the partition portion 111 extends radially form an inner side surface of the frame wall 11, and the partition portion 111 is preferably a reinforced fiber member.
  • the three-dimensional web core 20a is disposed on two opposing sides of the partition portion 111, and the three-dimensional web core 20a is connected to the frame wall 11 and the partition portion 111 by the adhesive material 40.
  • the partition portion 111 may extend continuously and diametrically across the receiving space of the frame body, the partition portion 111 includes a plurality of penetration holes (112) 112, the plurality of penetration holes 112 correspond to and are in communication with the plurality of channels 21, the three-dimensional web core 20a includes a first frame body 26 and a second frame body 27 disposed at opposing sides of the partition portion 111, the first frame body 26 and the second frame body 27 are connected to the frame wall 11 and the partition portion 111 by the adhesive material 40 (as a second embodiment shown in Figs.
  • the partition portion 111a may include an annular flange and annularly connected with the inner side surface of the frame wall 11,
  • the three-dimensional web core 20 includes a first frame body 26 and a second frame body 27 disposed at opposing sides of the partition portion 111a, the first frame body 26 and the second frame body 27 are connected to the frame wall 11 and the partition portion 111a by the adhesive material 40, the first frame body 26 and the second frame body 27 are connected by the adhesive material 40 (as a third embodiment shown in Figs.
  • first frame body 26 and the second frame body 27, preferably, each include an annular recess 261, 271 at the peripheral portion, the partition portion 111a is received within the annular recesses 261, 271 of the first frame body 26 and the second frame body 27, for providing flat striking surface portion and strong combination.
  • the partition portion can increase the structural strength and paddling effect, and the first frame body and the second frame body can be separately made and assembled so that the manufacturing is convenient and fast.
