Detailed Description

Referring to fig. 1, 2 and 3, a first embodiment of a racquet 100 of the composite structure of the present invention is adapted for ball striking.

The racket 100 includes a racket frame 101 and a string 102.

The racket frame assembly 101 includes a racket frame 104, and a grip 105 connected to the racket frame 104.

Referring to fig. 3, 4 and 5, the racket frame 104 includes a main frame body 1 and a reinforcing frame body 2.

The main frame 1 defines a face space 10 around an axis L1 for the mesh wire group 102 to cross, and includes an inner surface 11 defining a hollow 111, an outer surface 12 opposite to the inner surface 11, and two first protrusions 13 disposed on the outer surface 12 and spaced apart from each other.

The outer surface 12 has an inner face portion 122 and an outer face portion 121 spaced apart in a radial direction X1, and two side face portions 123 connecting the inner face portion 122 and the outer face portion 121 and extending in the radial direction X1, the inner face portion 122 being closer to the axis L1 than the outer face portion 121.

It should be noted that the radial direction X1 is an angle from a tangential direction X2, the tangential direction X2 is an extending direction of a tangent line of each point on the surrounding shape after the main frame 1 is in the surrounding shape, that is, the tangential direction X2 and the radial direction X1 of each point on the main frame 1 are different, and the radial direction X1 is parallel to an extending direction of a shortest distance between the inner surface portion 122 and the outer surface portion 121 at the corresponding position.

The first protrusion 13 is disposed on the inner surface 122 and defines a first recess 14.

The side portions 123 define a width D1, wherein a side portion 123 defines a side thickness D2 along the radial direction X1 and the inner portion 122 defines a wall thickness D3 along the radial direction X1.

The reinforcement frame 2 is made of a carbon fiber material around the axis L1, is disposed between the first protrusions 13 of the main frame 1, i.e., the first grooves 14, and is in contact with a portion of the outer surface 12.

Further, the reinforcing frame body 2 is a pre-impregnated carbon fiber material.

Preferably, the reinforcing frame 2 is attached to the inner surface 122 of the outer surface 12.

It should be noted that, in the present embodiment, the first protrusion 13 is formed by additionally protruding outward in the aluminum extrusion or molding process, in a first variation of the present embodiment, as shown in fig. 6, the first groove 14 may also be directly formed on the inner surface portion 122, and the first protrusion 13 is defined on the wall portion at both ends of the first groove 14.

In another variation of the number and the installation position of the reinforcing frames 2 in the present embodiment, please refer to the following paragraphs:

1. as shown in fig. 7, a second variation of the present embodiment includes a reinforcing frame 2, the first protrusion 13 is disposed on the outer surface 121 and defines the first groove 14, and the reinforcing frame 2 is disposed in the first groove 14.

2. As shown in fig. 8, a third modification of the present embodiment includes two reinforcing frames 2. The main frame 1 includes, in addition to the first protrusion 13 disposed on the inner surface 122, two second protrusions 15 disposed on the outer surface 121 and defining a second groove 16. The reinforcing frame 2 is disposed in the first groove 14 and the second groove 16, and contacts the inner surface 122 and the outer surface 121.

3. As shown in fig. 9, the fourth modification of the present embodiment also includes two reinforcing frames 2 and two second protrusions 15, similar to the second modification. The reinforcing frame 2 is disposed between each first convex portion 13 and the adjacent second convex portion 15, and contacts the side surface portions 123.

Referring to fig. 2 and 4, the through hole 3 penetrates through the main frame 1 and the reinforcing frame 2 along the radial direction X1. It should be noted that the through hole 3 is formed after the reinforcing frame 2 is attached to the main frame 1 (as shown in fig. 4), that is, when the main frame 1 and the reinforcing frame 2 are not combined (as shown in fig. 5), the main frame 1 and the reinforcing frame 2 do not have a hole.

In the aforesaid variation of the present embodiment, the through hole 3 passes through the main frame 1 and the reinforcing frame 2 in the first variation (as shown in fig. 6), the second variation (as shown in fig. 7) and the third variation (as shown in fig. 8), and the through hole 3 passes through only the main frame 1 in the fourth variation (as shown in fig. 9).

Referring to fig. 1 and 2, the mesh wire set 102 is crossed through the through hole 3 to form a racket face 103 suitable for hitting a ball.

It should be noted that the racket 100, the racket frame assembly 101 and the racket frame 104 of the present invention may be manufactured, sold or used separately.

From the above description, the advantages of the foregoing embodiments can be summarized as follows:

by providing the reinforcing frame body 2 made of a carbon fiber material having a low density and an excellent mechanical strength, the overall weight can be reduced and the effect of a high structural strength can be achieved while reducing the width D1, the side thickness D2 and the tube wall thickness D3 of the main frame body 1.

Further, since the density of the reinforcing frame 2 is 1.08 g/cc and the density of the main frame 1 is 2.54 g/cc, the weight of the entire racket frame 104 can be reduced by 17% even when the width D1 of the main frame 1 is reduced by 8%, the side thickness D2 is reduced by 25% and the tube wall thickness D3 is reduced by 7% by additionally installing the reinforcing frame 2.

Referring to fig. 10 and 11, a second embodiment of a racket 100 (see fig. 1) of a composite structure of the present invention, which is suitable for hitting a ball, is different from the first embodiment in that: the second embodiment comprises two reinforcing frames 2.

The reinforcing frame bodies 2 are disposed on the inner surface portion 122 at intervals along a direction perpendicular to the radial direction X1, that is, on two sides of the through hole 3, and the intervals between the reinforcing frame bodies 2 are to reserve a space for subsequent punching (forming the through hole 3).

Therefore, in addition to achieving all the effects of the first embodiment, since only the main frame 1 needs to be processed when the through hole 3 is formed by performing the subsequent punching process, the main frame 1 and the reinforcing frame 2 do not need to be processed at the same time as the first embodiment, thereby achieving the purpose of facilitating the processing.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the utility model is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
