Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a grip useful for being attached to a grip attachment for tennis, badminton, or ping pong rackets, bats, swords, and the like.

[Conventional technology]

Conventionally, for example, a racket for tennis or ping pong consists of a ball hitting part (11) and a grip (2) as shown in FIG. It has a prismatic shape with square sides.

[Problem to be solved by the invention]

With the grip of the conventional racket mentioned above, when gripped with the palm, the fingers are insufficiently fixed and slip easily, making it difficult to effectively apply the force of the arm to the racket when swinging the pole, and the grip slips from the palm. However, it is difficult to adjust the grip angle by quickly rotating the grip inside the book so that the ball hitting surface of the ball hitting part of the racket can be set at an arbitrary angle. In addition, the diameter (*diameter) of the grip in the direction parallel to the ball-hitting surface of the ball-hitting part is larger than the diameter (vertical diameter) in the direction perpendicular to the ball-hitting surface, so the palm of the grip is in close contact with the grip. To do so, the racket must be gripped from the side, making it difficult to quickly adjust the angle of grip of the racket in the palm of the hand when hitting the pole with both sides of the starting ball part of the grip being gripped from the side as hitting surfaces. Furthermore, since the center of gravity of the racket is located closer to the ball-striking part, it is difficult to grip the grip closer to the ball-striking part, and the moment of the racket cannot be used effectively.

[Means to solve the problem]

The present invention provides an intermediate portion Q4 that connects the root (2) to the knee root (2) via the neck a3, and a distal end portion ( To)
As a result, the root part forms a flat sphere a', and the diameter of the neck part is smaller than that of the root part (2), and the middle part α is parted and the neck part f91! The grip α is a prismatic body α9A, which is a columnar body with a circular or elliptical cross section whose diameter gradually expands from Q3, and the tip α9A is a prismatic body α9A with a plurality of vertical grooves α9B formed therein.
D.

[For production]

When grasping the grip of the present invention, place the tip of the thumb on the side of the base, and pinch the neck between the thumb, index finger, or middle finger. The little finger then engages with the longitudinal groove at the tip. Furthermore, when a weight is attached to the tip of the grip, the center of gravity of the grip attachment moves toward the tip of the grip. Furthermore, by making the vertical diameter of the grip 41 larger than the horizontal diameter, it is possible to grip the book with the palm of the hand in close contact with the grip both from the side and from the 4 length.

〔Effect of the invention〕

Therefore, in the present invention, since the root part is flat and concave, and the cross section of the middle part is elliptical, it is easy to rotate the grip with the palm of the hand, and adjust the size and angle. You can.

Also, the neck is smaller in size than the root and middle part, so when the thumb and index finger, or in addition the middle finger, hold the neck, the fingers are fixed by the root and middle part, so The grip is reliably prevented from slipping from the palm. Furthermore, if a weight is attached to the tip of the grip, the center of gravity of the grip attachment is moved toward the tip of the grip, so the grip attachment can be handled freely by gripping the tip of the grip.

r Example] A first embodiment of the present invention is shown in FIGS. 1-8.

Grip αn#-i flat spherical root ■ and the root (12)
an intermediate portion αΦ connected to via neck 0, and the intermediate portion αΦ
It consists of a tip (end) that connects to the The root of the neck ■
It consists of a cross-sectional circular column whose diameter is further reduced and whose diameter gradually expands from the middle part 04) to the neck @D.

In addition, a V-shaped length of 4 B is formed at the tip α9.
The prismatic body 09A is made of a prismatic body QSA with a cross-shaped cross section.
A weight OG of various weights (made of metals such as gold, silver, copper, iron, lead, tin, etc.) is attached to the tip of the holder so as to be replaceable by means of screwing, pasting, etc.

Desirable dimensions of each part of the grip aυ are as follows.

Maximum diameter of root υ A 20-401 QI Thickness of root ■ B 8 Diameter of crooked neck opening CI 6-26 fl Maximum diameter of intermediate part α4 0 20-40 fl Lateral diameter E of tip 09 Approximately 20 ff Vertical diameter of tip G9 F Approximately 40fi vertical groove (to) B and vertical 6
Distance with 5B G: 5f1 or more Side wall height H4- or more of longitudinal groove B Ru. There is a cutout QI in the vicinity of the attachment part αη of the plate αQ! JA is established.

When using the racket α9 mentioned above, grip the grip aη with your hands.At this time, place the tip of your thumb on the side of the root (2), and pinch the neck α3 between your thumb and index finger, or in addition to that, your middle finger. and engage the little finger in the vertical groove Q9B of the tip Q9. Then, Rakef) (1 (J (D) To adjust the grip angle, rotate the base υ with your thumb, slide the neck side or middle part α4 within your index finger or middle finger of the thumb, rotate the grip αυ as desired. At this time, since the plate agI of the racket α9 is provided with a cutout Q and A, the fingers should not hit the plate and interfere with rotation with the grip α. In this embodiment, since the vertical diameter is larger than the horizontal diameter, the grip (2)
You can hold it from the side and 41 even from the vertical position with your hands close together.

In cases other than the above embodiments, the vertical diameter F of the tip Mv is as shown in FIG.
' and the lateral diameter E' may be made equal. In this case, the vertical diameter F
' and the lateral diameter E' are preferably about 20 to 4 degrees, respectively. In addition, when the vertical diameter and the horizontal diameter are made equal, the intermediate part Q4
' is a columnar body with a circular cross section whose diameter gradually expands from the neck.

Further, the tip of the grip αυ may be formed into any shape such as a spindle-shaped tip (151) shown in FIG. 5, a slightly curved tip (162) shown in FIG. As shown in the figure, the best shape is to widen the end of the tip (15B).

Furthermore, the surface of the grip of the present invention may be coated with leather, rubber, etc. to prevent slipping, or patterns may be carved vertically or horizontally.

It goes without saying that the grip of the present invention can be applied not only to table tennis rackets, but also to grip attachments for tennis, badminton and other rackets, bats, swords, and the like. For example, when used as a grip for a badminton football, as shown in FIG.
ηA is screwed on to provide a badminton gear.
