Detailed Description

Applicants first describe herein, throughout this specification, including the examples and claims that follow, directional terminology will be used with reference to the orientation of the figures. Next, in the embodiments and the drawings to be described below, the same element numbers denote the same or similar elements or structural features thereof.

Referring to fig. 1 to 3, the racket frame 10 of the present invention includes a main body 20 and an elastic body 40.

The body 20 is made of fiber reinforced resin, wherein the fiber can be carbon fiber, glass fiber, boron fiber or kevlar fiber, and the resin can be thermosetting resin or thermoplastic resin. The body 20 has a circular frame 22, two supporting portions 24 and a holding portion 38, the front ends of the two supporting portions 24 are integrally connected with the circular frame 22, the rear ends of the two supporting portions 24 are mutually combined to form a trunk 28, the trunk 28 is integrally connected with the front end of the holding portion 38, the main body 28 has a groove 30 penetrating through the front and back surfaces, the longitudinal section and the cross section of the groove 30 are rectangular, the length direction of the groove 30 is parallel to the length direction of the holding portion 38, the groove 30 has an open end 32 facing the annular frame 22 and a closed end 34 facing the holding portion 38, and the trunk 28 has a positioning groove 36 with rectangular shape on both sides, the positioning groove 36 is communicated with the closed end 34 of the groove 30, the length direction of the positioning slot 36 is parallel to the length direction of the groove 30, and the width W2 of the positioning slot 36 is greater than the longitudinal section width W1 of the groove 30.

The elastic body 40 is made of an elastic material, such as Thermoplastic Rubber (TPR), Polyurethane (PU), Polystyrene (PS), or the like. The size and shape of the elastic body 40 are substantially matched with the size and shape of the groove 30, that is, the longitudinal section and the cross section of the elastic body 40 are both rectangular, and the rear end of the elastic body 40 is provided with two positioning portions 42 which are rectangular and have a larger width, so that the elastic body 40 is plugged into the groove 30 through the open end 32 of the groove 30 and forms a close fit with the groove 30, and is embedded into the two positioning grooves 36 of the trunk 28 by using the two positioning portions 42. In addition, as shown in fig. 5, the cross-sectional width W3 of the elastic body 40 gradually decreases from the middle to both ends, so that the elastic body 40 can improve the structural stability after being disposed in the groove 30, and as shown in fig. 4, one end of the elastic body 40 facing the annular frame portion 22 has a concave arc surface 44, and the concave arc surface 44 of the elastic body 40 engages with the inner circumferential surfaces 26 of the two supporting portions 24, so that the elastic body 40 maintains good integrity of the structural appearance after being assembled with the body 20.

Therefore, the racket frame 10 of the present invention can absorb the shock generated by the striking ball through the elastic body 40, so as to provide a very good shock absorption effect, and in addition, the elastic body 40 can be designed to have different colors according to actual needs, thereby presenting different visual feelings and recognizability.
