Description

Bowling Ball Insert Grip Set {Balling Ball Insert Grip Set}

This study devises the shape and shape of the outer circumferential surface of the bowling ball insert grip.

The bowl's insert grip set consists of one insert grip for thumb and two insert grips for heavy paper. The outside diameter and length of the insert grip set of the bowling ball are international standards. The thumb is formed as a cylindrical solid rubber with a diameter of 31.75 mm (5/4 inch) and a length of about 70 mm, and for heavy paper is 24.6 mm (31 / 32inch), it is usually formed of cylindrical soft rubber of about 45mm in length. At the same time, this standard is consistent with the size of the grip insertion hole of the bowling ball on which the insert grip is mounted. The insert grip of the bowling ball is a consumable item. If it is used for a certain period of time, the rubber part of the grip will wear out and should be replaced frequently. When replacing, the worn insert grips must be removed and removed, and the new insert grips must be joined to the grip insertion holes and glued together.

The conventional insert grip has a flat outer peripheral surface, so a new insert grip is inserted into the hole for inserting the grip and then adhesive is injected to fix it firmly. This is undesirably causing the deformation of the insert grip, there was a problem that the insert grip is easily separated or detached during the game even after bonding.

The present invention is designed to solve the problems as described above relates to the insert grip to facilitate the injection of the adhesive by forming a plaid pattern or comb (check) pattern on the outer peripheral surface of both edges (both ends) of the insert grip.

Each insert grip is used in the bowl insertion hole of the bowling ball, depending on the purpose. The insert grip alone has a weak bonding force and must be firmly attached using an adhesive.

The method of applying and bonding an adhesive to the inner wall of the grip insertion hole and the outer circumference of the insert grip has a weak binding problem. Recently, the insert grip is mainly fixed by the adhesive injection method after the insert grip is coupled to the grip insertion hole.

At this time, insert the grip into the hole for inserting the grip and adjust the direction of the grip sill. Then, the adhesive is injected. In the conventional insert grip set, the outer peripheral surface of the grip is smooth so that the adhesive In order to inject, the insert grip is opened toward the inner diameter to inject the adhesive. At this time, the adhesive hardens instantaneously and causes the adhesive not to spread evenly, or to cause the insert grip to deform, resulting in the mass production of defective products, discomforting the fingers during bowling games, and the hard adhesive touching the fingers to catch blisters. Caused to be injured.

Bowling ball sphere has three insert grip insert holes, one for inserting solid insert grip for thumb (hole for inserting thumb grip on bowling ball sphere 31.75mm (5/4 inch) ), And the other two are for inserting soft grips for medium and weak paper (inside the bowling ball sphere.Grip insert hole diameter 24.6mm (31 / 32inch), length 45mm inside and outside, and the inner diameter of each insert grip insertion hole of the bowling ball spherical and the outer diameter of each insert grip set are matched to each other so that each insert grip can be used in combination with the grip insertion hole in the bowling ball according to its purpose. It is.

In general, the bowl grip ball insert grip set is composed of one insert grip (reference numeral 110) for thumb and two insert grips (reference numeral 120, 130) for middle and middle finger, and the standard is as described above as an international standard.

The insert grip set of the present invention is characterized by forming grooves 111, 121 and 131 for adhesive injection in the left end and the right end (hereinafter referred to as both ends) of the cylindrical columnar shape.

The thumb insert grip 110 is usually made of solid rubber, and the inner diameter portion, that is, the inner diameter portion 112 is an elliptical boring tubular shape for inserting the thumb to be used according to the size of the male and female thumb, different in size. It is formed in the outer diameter portion, that is, the outer circumferential portion of the circular air flow groove 113 for allowing air to flow out when the grip is inserted into the bowling ball is formed from one letter from left to right.

In addition, the insert grips 120 and 130 for heavy paper are generally made of soft rubber made of soft raw rubber, and the inner diameter parts, that is, the inner diameter parts 122 and 132, have different sizes of finger insertion holes to be used depending on the thickness of the fingers. And the grip jaw (grip sill, 123, 133) is formed at both ends of the inlet so that the end of the finger to receive the elasticity.
