Paddle racket

Abstract

A paddle racket is provided, including: a frame body, including a frame wall and a handle connected to the frame wall, the frame wall having an inner circumferential surface and defining a receiving space; a three-dimensional web core, disposed in the receiving space and including an outer circumferential surface facing the inner circumferential surface, including channels disposed through the three-dimensional web core in a thickness direction of the three-dimensional web core; two striking surface portions, disposed on two opposing sides of the three-dimensional web core, each striking surface portions including through holes, the through holes corresponding to and being in communication with parts of the channels; and double-sided adhesive layers, connecting the outer circumferential surface of the three-dimensional web core to the inner circumferential surface of the frame wall and connecting the two striking surface portions to the two opposing sides of the three-dimensional web core.

What is claimed is: 
     
         1 . A paddle racket, including:
 a frame body, including a frame wall and a handle connected to the frame wall, the frame wall having an inner circumferential surface and defining a receiving space;   a three-dimensional web core, disposed in the receiving space and including an outer circumferential surface facing the inner circumferential surface, including a plurality of channels disposed through the three-dimensional web core in a thickness direction of the three-dimensional web core;   two striking surface portions, disposed on two opposing sides of the three-dimensional web core, 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 parts of the plurality of channels; and   a plurality of double-sided adhesive layers, connecting the outer circumferential surface of the three-dimensional web core to the inner circumferential surface of the frame wall and connecting the two striking surface portions to the two opposing sides of the three-dimensional web core.   
     
     
         2 . The paddle racket of  claim 1 , wherein one of the inner circumferential surface and the outer circumferential surface includes an annular convex surface, the other of the inner circumferential surface and the outer circumferential surface includes an annular concave surface, and the annular convex surface and the annular concave surface are connected by one of the plurality of double-sided adhesive layers. 
     
     
         3 . The paddle racket of  claim 1 , wherein the three-dimensional web core is resiliently deformable. 
     
     
         4 . The paddle racket of  claim 1 , wherein the plurality of channels include a plurality of first channels and a plurality of second channels corresponding to and being in communication with the plurality of through holes, the plurality of first channels are disposed through the three-dimensional web core in the thickness direction, and the plurality of second channels extend through the three-dimensional web core in a direction inclined to the thickness direction. 
     
     
         5 . The paddle racket of  claim 4 , wherein a first portion and a second portion of the plurality of second channels are transverse to each other and overlap with each other in the thickness direction. 
     
     
         6 . The paddle racket of  claim 4 , wherein the three-dimensional web core further includes a plurality of curved walls, the plurality of curved walls define the plurality of first channels and the plurality of second channels, the plurality of curved walls include a plurality of perforations disposed therethrough and in communication with the plurality of first channels and the plurality of second channels. 
     
     
         7 . The paddle racket of  claim 1 , wherein each of the two opposing sides of the three-dimensional web core includes a plurality of ribs, the two striking surface portions and the plurality of ribs are connected by the double-sided adhesive layer, and each of the plurality of ribs has a width smaller than one half a diametric dimension of each of the plurality of channels. 
     
     
         8 . The paddle racket of  claim 7 , wherein the three-dimensional web core defines a diametric direction, at least one of the plurality of ribs continuously extends from side to side between the two opposing sides of the three-dimensional web core in a direction parallel to the diametric direction, and parts of the plurality of ribs extend in intervals between the two opposing sides of the three-dimensional web core in a direction parallel to the diametric direction. 
     
     
         9 . The paddle racket of  claim 1 , wherein at least one of the plurality of double-sided adhesive layers between each of the two striking surface portions and one of the two opposing sides of the three-dimensional web core includes a first adhesive side and a second adhesive side, the first adhesive side is adhered to the three-dimensional web core, the second adhesive side is adhered to the striking surface portion, and the adhesion of the second adhesive side is greater than the adhesion of the first adhesive side. 
     
     
         10 . The paddle racket of  claim 1 , wherein at least one of the plurality of double-sided adhesive layers between the inner circumferential surface and the outer circumferential surface includes a first adhesive side and a second adhesive side, the first adhesive side is adhered to the inner circumferential surface, the second adhesive side is adhered to the outer circumferential surface, and the adhesion of the second adhesive side is greater than the adhesion of the first adhesive side.
