Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a racket for playing tennis or badminton.

[0002]

2. Description of the Related Art In general, a racket used for tennis or badminton is provided with a frame having an opening extending on a vertical plane at an upper end portion of a vertically extending rod-like gripping portion, and a frame for closing the opening. And a gut attached in a lattice pattern. In the case of such a conventional racket, in order to attach a gut to a frame, a specific device is required, and some skill is required. Therefore, when the conventional racket gut is cut,
It was not possible to easily replace guts on the spot.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a racket in which guts can be easily and easily replaced.

[0004]

The inventor of the present invention has conducted various studies to solve the above-mentioned problems, and as a result, has found that a frame forming an opening extending on a vertical plane at the upper end of a vertically extending rod-shaped gripping portion is provided. A frame that forms a hole corresponding to the opening, a gut is attached to the frame in a grid pattern so as to cover the hole, and is removably fitted to the opening of the frame. We have found that a racket consisting of a ball striking surface can solve the problem. Hereinafter, the present invention will be described in detail.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment FIG. 1A is a front view of a racket 1 as one embodiment of the present invention. This racket 1 is shown in FIGS.
As shown in FIG. 3, the frame 11 includes a hitting surface portion 21 and an auxiliary frame 31. Frame 11 of the present invention
In an upper end portion 13 of a bar-shaped grip portion 12 extending vertically, an opening portion 14 extending on a vertical plane is formed. As shown by a dotted line in FIG. 1B, the frame 11 has a groove 15 formed on the inner surface of the opening 14 along the opening 14. Here, the thickness (length in the direction perpendicular to the paper surface) of the frame where the opening 14 is formed is about 20 mm, and the width of the frame where the opening 14 is formed is about 20 mm. The width (length in the direction perpendicular to the paper) of the groove formed along the opening 14 is about 6 mm, and the depth is about 5 mm. That is, the end of this groove is approximately 7
mm.

Further, an insertion hole 16 communicating with the opening is provided on the outer peripheral side surface of the frame 11. The insertion hole 16 extends from the upper end 16 ′ on the right side of the frame to the lower end 1.
6 ". Here, this insertion hole 1 is formed.
The width of 6 (the length in the direction perpendicular to the paper) is about 10 mm.

On the other hand, the striking surface portion 21 of the present invention
And a hole 22 having substantially the same size and shape as the opening 14 formed in the frame 11.
Here, the thickness of this frame 23 (length in the direction perpendicular to the paper surface)
Is about 9 mm. A gut 24 is attached to the frame body 23 in a lattice shape to form a racket surface.

[0008] The striking surface portion 21 on which the gut is stuck in a lattice shape is fitted into an opening portion 14 of the frame through an insertion hole 16 formed in the frame 11. Further, the striking face portion 21 has a flange 25 formed along the outer peripheral edge of the frame 23. This flange 2
5 is designed to engage with a groove 15 formed along the opening of the frame when the striking surface 21 is fitted into the opening 14 of the frame 11. The width of the flange 25 (length in the direction perpendicular to the paper) is about 5.8 mm.
It has become.

Then, the auxiliary frame 31 is fitted into the insertion hole 16 formed in the frame, and
Are fixed to the frame 11.

As described above, in the racket of the present invention, since the striking surface portion 21 to which the gut is attached is removably fitted to the frame 11, the gut can be replaced very easily. .

Second Embodiment FIG. 2 is a front view of a racket according to a second embodiment of the present invention. This racket has a bar-like gripper 12 extending vertically.
A frame 11 ′ forming an opening 14 extending on a vertical plane at the upper end 13 of the frame, and a hole corresponding to the opening, and a gut is attached in a lattice shape so as to close the hole,
And a striking surface portion removably fitted to the opening 14 of the frame 11 '. In the racket frame 11 'according to the second embodiment of the present invention, a groove 15 is formed along the opening 14 on the inner surface of the frame 11' as shown by a dotted line in FIG. Also, this frame 11 '
As shown in the side view in FIGS. 2B and 2C, the first part is divided into a front part 18 ′ and a back part 18 ″ around a hinge 17 provided at the upper end of the frame 11. A hitting surface portion 21 similar to that described in the embodiment is fitted.

After the striking face 21 is fitted along the opening 14 of the frame, the frame 11 '
8 ′ and the back surface 18 ″ are again associated with each other. Thereafter, the grip 13 near the lower end of the frame 11 ′ is formed.
By rotating the hook 19 attached to the, the striking surface portion 21 can be fixed and can be used as a racket.

The racket shown as the second embodiment has a frame 11 'similar to the racket described in the first embodiment.
Hitting surface portion 21 with a gut attached to opening 14 of
Are removably fitted, so gut replacement is very easy.
