The user is thus capable of making a shot with his backhand while keeping his fingers on the finger putting portion 14 without re-holding the grip 5.

Description

[Detailed description of the invention] [Industrial application fields] The present invention relates to a racket such as a tennis racket.

[Prior Art] A racket, for example, a tennis racket, has a ball-hitting part formed by extending a gut on an annular frame, and a handle rod is connected to the ball-hitting part, and the end of the handle has a rod. A grip with a leather band wrapped around it to prevent slipping is attached.

[Problems to be Solved by the Invention] When playing tennis, etc., the grip is not held in a fixed position all the time. In other words, the fore-
The grip is different for hand, backhand, and do. For this reason, for example, when switching from forehand to backhand, it was necessary to hold the racket with the opposite hand to the listening hand, and then change the grip of the attacking arm. As described above, with conventional rackets, it is necessary to change the grip depending on the shot, and therefore it is not possible to always maintain an accurate grip.

SUMMARY OF THE INVENTION An object of the present invention is to provide a racket that solves the above-mentioned problems and allows shots to be made without changing the grip.

[Means for Solving the Problems] According to the present invention, a grip is rotatably provided on a handle bar connected to a ball-hitting part coaxially with the handle part.

[Function] The ball-hitting part or the handle is held on the side opposite to the hitting arm's hand, and the grip can be rotated by a predetermined angle relative to the ball-hitting part while the hitting arm's hand is still holding the grip.

[Example] Fig. 1 shows a first example, in which 1 is a ball hitting part;
The ball-hitting section 1 is constructed of a ring-shaped frame 2 with a gut 3 stretched over it, and a handle rod 4 is connected to the ball-striking section 1. Reference numeral 5 denotes a grip provided at the end of the handle rod 4 coaxially with the handle rod 4, and is rotatably connected to the handle rod 4.

The shaft rod 4A of the handle rod 4 has recesses 7 at predetermined angles.
A cam 18 formed on the outer periphery is coaxially fixed, and the recess 7 is curved and recessed. Further, the grip is hollow, and a stopper rod 9 oriented in the axial direction is arranged in an annular shape inside the grip, and this stopper rod 9 is elastically attached to the outer circumferential surface of the cam plate 8 by a leaf spring 10. are doing. These cam plates8. Fixed machine with stopper rod 9! s11 is configured. The end of the shaft rod 4A protrudes from the end surface of the grip 5, and is fitted with a stopper 11 to prevent removal. Note that a finger rest part 14 is recessed on the outer peripheral surface of the grip 5, and this finger rest part 14 can be used for a predetermined grip, for example, a forehand grip, when the upper surface of the grip 5 is parallel to the upper surface of the handle rod 4. It is formed to be.

First, the player grips the finger grip part 14 and shoots a forehand shot. Next, when shooting a backhand shot, support the handle rod 4 with the hand opposite to the firing arm, and turn while holding the grip 5, so that the stopper rod 9 resists the leaf spring 10 and returns to the original position. Separate from Wei 7 and move on to neighboring Ko 7
When the user stops rotating the grip 5, the stopper rod 9 is landed in a predetermined groove 7. As a result, the grip 5 is rotated at a predetermined angle with respect to the handle 4 and fixed, and the finger rest can be moved to the part 14 without changing the grip 5.
You can shoot the puck while keeping your finger on.

FIG. 2 shows a second embodiment, in which a shaft rod 22A having a disk 23 fixed thereto is fixed coaxially to the end of a handle rod 22 connected to the ball-hitting part 21, and A plurality of small holes 24 are formed in a ring shape. The finger rest is the grip 2 forming the part 25.
Reference numeral 6 is hollow, and a grip 26 is rotatably provided in this hollow portion 27 with a shaft 22A of the handle rod 22 via a bearing 29. Also, the end of the shaft rod 22A has a grip 26.
This protrusion is inserted outward from the end face, and a removal stopper 30 is attached to this protrusion. Furthermore, a stopper rod 31 that can be inserted through the small hole 24 is provided in the hollow portion 27 so as to be movable in the axial direction only, and this stopper rod 31 can be driven forward and backward by an electromagnet 32 fixed to the grip 26. It has become. 33 is a return spring.

The reference numeral 34 designates a battery cover for a battery provided within the grip 26, and the reference numeral 35 designates a push button switch provided at a location corresponding to the thumb or index finger of the finger rest portion 25.

36 is a grip 2 consisting of the stopper rod 31, etc.
6 fixing mechanism. Therefore, when the handle rod 22 is supported with one hand and the push button 35 is pressed with a thumb or the like, the electromagnet 32 is energized and the stopper rod 31 is advanced by the spring 33 and inserted into the small hole 24. Then, after rotating the grip 26 by a predetermined angle while holding it, press the button switch 35 with your thumb.
When released, the electromagnet 32 becomes de-energized and the stopper rod 31
is inserted into the small hole 24 to lock the grip 26 to the handle rod 22. In this state, you can shoot without changing your grip on the grip 26.

In this way, the stopper rod 31 is moved forward and backward toward the small hole 24 side by the electromagnet 32 operated by the push button 35,
The rotatable grip 26 can be locked onto the handle rod 22, making it easy to lock. Furthermore, since a large number of small holes 24 are formed, the grip 25 can be locked at a desired angle.

FIGS. 3 and 4 show a third embodiment of a double-hand type, in which a grip 43 is rotatably provided at the end of a handle rod 42 connected to a ball-hitting part 41. A double-handed grip 44 is fixed to a handle rod 42 connected to this grip 43, and these grips 43 and double-handed grip 44 have recessed finger rests 45 and 46, respectively. .

A shaft rod 47 is coaxially connected to the handle rod 42, and a grip 43 is rotatably provided on the shaft rod 47. Further, the grip 43 is provided with a push button 48, and the push button 48 is configured to move forward and backward a stopper rod 50 provided on the sliding body 49A via a link mechanism 49.

Then, the stopper rod 50 is inserted into a small hole 51 of a disc 47A fixed to the shaft rod 47 so that it can be locked. These stopper rods 50, link machine 1'i49
The fixing mechanism 52 is configured by the above.

FIG. 5 shows a fourth embodiment, in which a ball-hitting portion 61 has a handle rod 6.
