Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an improvement in the gripping surface of a grip in a shake-hand type racket.

[Conventional technology]

Conventionally, the grip of a shake-hand type racket has a gripping surface formed of a straight plane.

By the way, when a person grasps an object in a relaxed state, the four fingers from the index finger to the little finger form an arcuate surface with the middle finger as the outermost end on the inside of the grasping hand, facing the wrist. The grasping mode is such that a protruding arcuate surface is formed by the surface of the thumb ball muscle at a position opposite to this arcuate arcuate surface, and the end of this protruding arcuate surface is curved toward the wrist.

However, in contrast to the hand that takes the above-mentioned gripping mode, the grip that is gripped has a gripping surface that is a straight plane, which causes the following problems when using the racket.

The grasping surface of the grip only partially contacts the inner surface of the hand, and gripping of the grip held on the inner surface of the hand tends to become unstable, and the rotation of the grip within the hand makes it difficult to handle the movement of the arm or wrist. There is a risk that you will not be able to respond quickly or that the angle of the racket surface will become inaccurate.

Since the contact of the grip with the thumb muscle is limited to only the apex of the protruding arcuate surface, the lower end of the grip is in a non-contact state, which causes the grip to shake in the hand when using the racket, and the hitting force due to the deviation of the hitting point. There is a risk that the transmittance of

(Problem to be Solved) The problem to be solved by the present invention is to form the gripping surface of the grip into a shape that fits closely to the palm of the hand.

(Means for Solving the Problems) The means of the present invention for solving the above-mentioned problems is to make one of the two surfaces of the gripping surface perpendicular to the ball-striking surface of the grip the inside of the hand that grips the grip. One side of the hand is formed into a protruding curved surface along the arcuate surface formed by the middle finger, ring finger, and little finger, and the other side is formed into an arcuate curved surface along the arcuate surface formed by the thumb muscles on the inner surface of the hand. , a protruding curved surface along the end of the thumb muscle muscle is continuously formed at the end of the arcuate curved surface.

(Function) The effect of the above means is that the protruding curved surface comes into close contact with the arcuate surface formed by the middle finger, ring finger, and little finger on the inner surface of the hand holding the grip, and the arcuate curved surface comes into close contact with the arcuate surface formed by the middle finger, ring finger, and little finger on the inner surface of the hand holding the grip. It is in close contact with the arcuate surface formed by the thumb muscle, and the protruding curved surface is in close contact with the end of the thumb muscle on the inner surface of the hand.

(Effects) With the above configuration, the present invention has the following effects.

One of the two surfaces of the grip surface perpendicular to the ball-striking surface is formed into a protruding curved surface along the arcuate surface formed by the middle finger, ring finger, and little finger on the inner surface of the hand that grips the grip; The other surface is formed into an arcuate curved surface along the arcuate surface formed by the thumb muscle on the inner surface of the hand, and a protruding curved surface along the end of the thumb muscle is connected to the end of the arcuate curved surface. , all of the gripping surfaces of the grip naturally come into close contact with the palm of the hand gripping the grip, effortlessly preventing rotation of the grip in the circumferential direction, and all of the ends of the gripping surface of the grip naturally come into close contact with the palm of the hand, which prevents the grip from rotating in the circumferential direction. Effortlessly prevents lateral wobbling and responds quickly to arm and wrist movements when using the racket.
To provide a racket that accurately angles the racket surface and reliably transmits hitting force.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The table tennis racket main body A consists of a ball hitting surface part 1 and a grip 2.

As in the past, the ball hitting surface section 1 is formed of a plate material of a desired size, weight, and shape for all-round use, front attack, etc., and its front and back surfaces are used as the ball hitting surface 1a.
A grip 2 is integrally attached to the side surface 1b on the central extension line of the ball hitting surface 1a, and a desired rubber (not shown) is attached to the ball hitting surface 1a during use.

The grip 2 is a grip portion formed to have a thickness and length that can be grasped by the user, and is made up of a grip mounting portion 2a and a grip member 2b, and has a side surface 4, a back surface 5, and a gripping portion consisting of left and right curved surfaces 6, 7. The surface 3 and its base end are integrally attached to the side surface 1b of the ball hitting surface portion 1.

The left and right curved surfaces 6 and 7 are two surfaces perpendicular to the ball hitting surface 1a of the gripping surface 3, and are curved from the base end to the distal end, one of which is a protruding curved surface 6, and the other is an arcuate curved surface. A protruding curved surface 8 is formed by connecting a protrusion to the end of the arcuate curved surface 7.

The protruding curved surface 6 is formed into a protruding curve along the arcuate surface 9 formed by the middle finger, ring finger, and little finger on the inner surface of the hand holding the grip 2.

The arcuate curved surface 7 is formed into an arcuate curve along the protruding arcuate surface 10 formed by the thumb ball muscle on the inner surface of the hand.

Incidentally, in this embodiment, the respective curvatures 6 and 7 are
is formed from the proximal end to the distal end of the gripping surface 3,
It is also optional to provide it in the middle of the gripping surface 3.

The protruding curved surface 8 is formed into a curve along the end of the thumb muscle muscle 11 which curves toward the wrist on the inner surface of the hand.

Further, the front surface 4 and the back surface 5 are two surfaces parallel to the ball hitting surface 1a of the gripping surface 3, and are formed into straight planes as in the conventional art.

The grip mounting portion 2a is formed by integrally extending a desired portion of the ball hitting surface 1a in a direction parallel to the ball hitting surface 1a to have a width and length that allows grip, and has a grip member on the front and back surfaces parallel to the ball hitting surface 1a. Attach 2b.

The grip member 2b is a plate material having a desired thickness,
The outer shape is formed to be substantially the same as that of the grip attaching portion 2a, and the back surface is attached to the grip attaching portion 2a with the outer shape flush with the outer shape of the grip attaching portion 2a.

The surface of the grip member 2b forms the front surface 4 or the back surface 5 of the gripping surface 3, and the left and right side surfaces of the grip member 2b and the grip mounting portion 2a form the left and right curved surfaces 6, 7 of the gripping surface 3.

In addition, if the user is right-handed, the ball hitting surface 1a with the protruding curved surface 8 on the right side is the forehand surface,
In the case of a left-handed player, the ball-hitting surface 1a with the protruding curved surface 8 on the left side is used as the forehand surface, and a desired rubber is attached thereto.
