  • Publication number: 20170136718
    Abstract: A method of making a composite board and a product made thereby are disclosed. The method includes a lining forming step, a fiber pipe rolling step, a fiber pipe mounting step, a fiber material covering step, and a board body forming step. The product includes a lining acting as a board body, a plurality of long slots formed on the lining, a fiber pipe placed in each of long slots, a foam material mounted in each of fiber pipes, and a fiber material covering an external periphery of the lining. The fiber materials and the fiber pipes are melted and combined together by heat, thereby shortening the operating time. The fiber pipe becomes a reinforcement support structure to increase a structural strength of the composite board, thereby producing a finished product with a light weight and a strong structure.

  • Patent number: 8608596
    Abstract: A racket with a movable throat includes a racket frame having an inner wall disposed with a pivotal groove having a throat member received therein. A racket net is firmly fixed with the inner wall of the racket frame, composed of a plurality of first main strings respectively having one end connected with the throat member. By so designing, when a user employs the racket of this invention to hit balls, the impact force of the ball dashing against the racket net will drive the throat member to sway. Thus, the time that the ball contacts with the racket net can be prolonged to enable a user to control balls more easily and additionally, all the first main strings can be actuated to sway together with the throat member to produce greater resilient force for enhancing power of hitting balls.
