It relates to a detachable insert grip for a bowling ball that can lower the production cost because one grip grip is used by forming an insertion hole.

In general, bowling is an indoor game in which 10 non-metallic pins are rolled and rolled down on the end of a lane with a prescribed length and width.

Ten pins bowling using 10 pins is common, but nine pins bowling using 9 pins is also available. Outdoors include lawn bowling and candle pin bowling in which pins are shaped like candles.

In addition, the bowling ball has a standard size, and the outer diameter is φ218.095 mm. The weight of the ball varies according to the user's preference, ranging from 8 pounds to 16 pounds by 1 pound. The upper and lower sides are divided according to the center of gravity. .

Bowling is one of the most common sports used by the general public for hobbies, etc. After lifting the thumb, middle finger, and cotton ball into a bowling ball with a gripping hole, roll it toward the pin in the lane and add a turn to knock the pin down. It is a game that sums the number of pins that have fallen, so that the result can be known.

In addition, a rubber insert insert is inserted into the gripping hole so that a finger node can be closely attached to the gripping hole where the thumb, middle finger, and cotton paper are inserted.

The insert grip of a bowling ball consists of one insert grip for thumb and two insert grips for Chinese medicine.

The outer diameter and length of the insert grip of the bowling ball is an international standard, and is formed as a 31.75 mm (5/4 inch) diameter for thumb and a cylindrical solid rubber around 70 mm in length. 32inch), and is usually formed of a cylindrical soft rubber of about 45㎜ in length. At the same time, this standard is to match the size of the hole for inserting the grip of the bowling ball to which the insert grip is mounted.

On the other hand, the insert grip of a bowling ball is a consumable item and if used for a certain period of time, the rubber in the grip part wears out and needs to be replaced frequently. When replacing, the worn insert grip must be removed and removed, and the new insert grip should be attached to the grip insertion hole and glued.

However, since such an insert grip is fixed to one bowling ball, there is a problem that it cannot be used in other bowling balls. If the insert grip is used as a consumable part for a period of time, the insert grip must be removed and removed as the grip portion wears. There is a problem that a new insert grip must be adhered.

In order to solve this problem, a detachable insert grip having a finger angle adjustment function for a bowling ball, which is Korean Patent Registration No. 10-1702613, has been developed and disclosed.
