Description

[Technical Field]

[0001] The present invention relates to a handle grip, and more particularly to a handle grip having a raised portion on its surface. [Background technology]

[0002] A golf club has a head at the tip of a shaft and a grip at the base end. A golf player grips the grip at the base end, raises the shaft, and swings the club to hit the ball with the head.

[0003] Golf clubs used in this way are made of a non-slip elastomer to prevent the golf club from slipping out of the gripping hand during a swing. Furthermore, some conventional grips, as described in Patent Document 1, have recesses or protrusions on the surface of the grip to enhance the anti-slip effect. Patent Document 2 also shows a configuration in which desired information is added to the grip by printing letters on the surface of the grip. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Special table number 2022-506619 [Patent Document 2] Patent No. 5583347 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, the way a golf club is gripped may be changed in order to improve the hitting technique. For example, if we take the swing of a right-handed player as an example, there are three types of thumb positions when holding the grip with the left hand: weak grip, square grip, and strong grip. With a weak grip, the left thumb is directly above the center line of the grip. With a square grip, the left thumb is along the center line of the grip, slightly to the right of directly above. With a strong grip, the left thumb is along the right side of the grip.

[0006] There are also different ways to hold the club, such as the finger grip, which is held with the fingers of the left hand, the palm grip, which is held with the palm of the hand, and the semi-finger grip, which is held at the base of the fingers. There are also different ways to place the thumb on the grip, with the thumb tucked in and the thumb extended. Furthermore, there are also grips unique to each player, depending on their individual hitting habits. As described above, there are many different ways to hold the grip, and the position on the grip that is transmitted from the hand holding the grip to the golf club varies slightly depending on the individual and the gripping method.

[0007] Conventional grips have convex or concave portions on the surface of the grip during the manufacturing process, making it difficult to change the position of the convex or concave portions to suit the player's habits or changes in hitting style. An object of the present invention is to provide a grip having a handle portion provided with protrusions depending on how the user holds the grip. [Means for solving the problem]

[0008] The grip of the gripping portion of the present invention, which solves the above problems, is as follows: A grip provided on a portion to be held by the palm, The grip body and an outer surface that is gripped by the palm of the hand; a display unit made of elastomer and provided in any shape at a desired position on the outer surface, The display unit is provided on the outer surface as a retrofit, A grip of a holding portion characterized in that the outer surface is raised above the outer surface to an extent that it can be recognized by the touch of the palm or the pads of the fingers holding the outer surface. With such a grip, a display unit can be added later, so that the raised display unit can be provided at a position that suits the size of the user's palm and their unique gripping style.

[0009] The grip body has at least an outer surface made of elastomer, which provides a non-slip effect when the grip is held. If the elastomer constituting the display unit is made of a material different from the material constituting the grip body, the display unit will be more visually and tactually recognizable because it is made of a different material from the body.

[0010] By providing the display portion at a position where it can be gripped by hand, it is possible to provide an anti-slip effect to the display portion. By forming the display portion into a character or symbol shape, it is possible to make the display portion carry specific information.

[0011] The elastomer that makes up the display unit is made of a softer material than the material that makes up the grip body, so that the anti-slip effect can be more easily and fully exerted when held in the palm of the hand. [Effects of the Invention]

[0012] According to the grip of the holding part of the present invention, a display unit can be added later, so that the raised display unit can be placed at any position according to the size of the user's palm and their unique gripping style. [Brief explanation of the drawings]

[0014] One embodiment of the golf club grip of the present invention will be described in detail below. The grip of the gripping portion of the present invention is a grip attached to the part held by the hand, and may be a grip attached to the outside of the gripping portion, or the grip itself may constitute the gripping portion. A grip for a golf club will be described below as one embodiment of the present invention. Fig. 1 is an overall plan view of the golf club grip of the present invention, Fig. 2 is an overall perspective view of a golf club, and Fig. 3 is an overall plan view of the grip held in the palm of the hand.

[0015] 2, the golf club 1 to which the golf club grip 4 of the present invention is attached includes a shaft 2, a head 3 provided at the tip of the shaft 2 and used to hit a golf ball, and a grip 4 provided at the rear end of the shaft 2. The golf club 1 is an item used to hit a ball in a golf game, and is used as follows.

[0016] A golf player standing next to a golf ball holds the grip 4 of the golf club 1 with both hands, addresses the ball by placing the head 3 over the golf ball, makes a backswing while holding the grip 4 with both hands, swings up the golf club 1, transitions from the top to a downswing, hits the ball with the head 3, transitions to a follow-through, and finishes the swing.

[0017] As described above, the grip 4 is a part to be held with both hands. The configuration of the grip 4 will be described in detail below. As shown in FIG. 1 , the grip 4 has a cylindrical grip body 41 and a shaft connecting portion 42 to which the base end of the shaft 2 is connected. The grip body 41 is made of an elastomer, and can be made of, for example, a rubber-based elastomer such as natural rubber or synthetic rubber, or a resin-based elastomer such as a silicone elastomer, a polyurethane elastomer, or a fluoroelastomer. By using these materials, sufficient frictional resistance is generated between the grip 4 and the palms of both hands holding the grip 4, allowing the golf club 1 to be securely gripped. The grip body 41 may be made of an outer layer and an inner layer, with at least the outer layer being made of the elastomer described above.

[0018] The grip body 41 is formed in a rod shape that follows the shaft 2, and a hole into which the shaft 2 is inserted is formed in the axial direction in the shank, and this hole serves as the shaft connection part 42. The shaft 2 is inserted into a tip opening 421 of the shaft connection part 42, and the shaft 2 is inserted over the entire length of the grip body 41. A cover 43 is connected to a rear end opening 422 of the shaft connection part 42 to close the opening. The grip body 41 is configured so that its cross-sectional area gradually increases from the front end 411 to the rear end 412, and the cross-sectional shape is circular, with the diameter D of the circle increasing linearly. Due to this configuration, the thickness t of the shaft connection portion 42 increases linearly toward the rear end.

[0019] Display units 5A and 5B are provided on the outer surface 410 of the grip body 41, which has an arc-shaped cross section. As shown in Fig. 3, display unit 5A is positioned where the thumb HLt of the left hand HL would be when the player holds the golf club 1 and decides their stance for the shot, and grips the grip 4 so that the face 31 of the head 3 is positioned perpendicular to the hitting direction. As shown in Fig. 4, display unit 5B is provided in a position where the bases HLb of the four fingers of the palm of the left hand HL would overlap.

[0020] Since display units 5A and 5B have the same configuration, only display unit 5A will be described and a description of display unit 5B will be omitted. The components that make up display unit 5A are six Roman letters: "S" 51a, "A" 51b, "S" 51c, "A" 51d, "K" 51e, and "I" 51f. The arrangement of these letters creates a specific meaning, and when read in Roman letters, they are pronounced "Sasaki," which in this embodiment represents the surname of the owner of golf club 1. The characters that make up display unit 5 are not limited to Roman letters and may be, for example, hiragana, katakana, kanji, etc., or characters used in other languages.

[0021] The meanings indicated by the characters on the display unit 5 include the owner's name, the golf club manufacturer, grip manufacturer, and brand name, the type of shot, and the name of the ball's trajectory. Specifically, the display unit 5 is provided at the location where the left thumb would be positioned when hitting a bunker shot, corresponding to the grip position when hitting a bunker shot. In this case, if the characters on the display unit 5 read "Bunker Shot," the player can intuitively know the grip position when hitting a bunker shot. Furthermore, the display unit 5 is provided at the location where the left thumb would be positioned when hitting a fade ball, corresponding to the grip position when hitting a fade ball. In this case, if the characters on the display unit 5 read "Fade," the player can intuitively know the grip position when hitting a fade ball.

[0022] Furthermore, the display is not limited to letters, but may be figures or symbols, etc., and it is preferable that the display unit 5 as a whole is configured to convey a specific meaning. Each component of the display unit 5 is made of elastomer. This elastomer may be the same material as the elastomer that makes up the grip body 41, but it is preferable that the color is different. This is because this makes the display unit 5 easier to see.

[0023] Furthermore, it is preferable that the elastomer of the display unit 5 is a different material from the elastomer that constitutes the grip body 41. In particular, it is preferable that the material has a different surface feel. This is because the location of the display unit 5 can be easily found when touched with the palm or fingers. Furthermore, as shown in FIG. 5, the display unit 5 is raised higher than the outer surface 410 of the grip body 41. The degree of this protrusion is such that it is easily noticeable by touch when gripping the grip 4 with the fingers or palm.

[0024] FIG. 4 is a cross-sectional view of the grip 41 with the thumb HLt placed on it. As shown in FIG. 4, the element 51f of the display unit 5A is pressed into the pad of the thumb HLt, protruding from the outer surface 410. The location of the display unit 5A can be determined by touch alone, allowing the user to easily locate the display unit 5A and place the thumb HLt on that area. Furthermore, the protrusions dig into the pad of the thumb, providing a non-slip effect. The non-slip effect can be further enhanced by using a material that is softer than the material of the grip body 41. As such, the material for the display unit 5 is not limited to elastomers, but thermoplastic resins, such as thermoplastic acrylic resins and other resins, can also be used. Acrylic materials are also acceptable, and high-viscosity paints or inks can be used to raise the display unit 5 above the outer surface 410.

[0025] The position of the display part 5B is such that when the grip 4 is held with the palm HL of the left hand, the bases HLb of the four fingers overlap, allowing the gripping force to be fully transmitted from the palm of the hand, and enabling the anti-slip effect to be more fully exerted. In order to fully exert this anti-slip effect, the preferred position for providing the display unit 5 is a position where the thenar eminence HLc and hypothenar eminence HLd of the palm of the hand come into contact when the grip 4 is held with the left hand.

[0026] Furthermore, as shown in FIG. 3 , when gripping the grip 4, the right hand HR is placed over the thumb HLt of the left hand HL. In this case, the grip 4 is sandwiched between the base of the right thumb HRt and the right index finger HRp. Therefore, the display unit 5 for this slip prevention should be located in a position where the right thumb HRt is placed along the grip 4, i.e., a display unit in which the components are arranged in order in a counterclockwise spiral direction (arrow B direction) from near the tip of the left thumb HLt to the tip of the grip 4 when gripping with the left hand HL. Similarly, the display unit 5 should be located in a position where the right index finger HRp is placed along the grip 4, i.e., a display unit in which the components are arranged in order in a clockwise spiral direction (arrow A direction) from near the tip of the left thumb HLt to the tip of the grip 4 when gripping with the left hand HL. In this way, the display unit 5 may be arranged in a direction along the axial direction of the grip 4, or in a circumferential or spiral direction.

[0027] Such a display unit 5 is also provided at the tip portion of the grip body 41. When it is necessary to swing the golf club 1 with a grip shorter than the actual club length, one method is to grip the tip portion of the grip 4 and swing. To accommodate this type of usage, display units 5C and 5D are provided at the tip portion of the grip body 41. As with display units 5A and 5B, display unit 5C is located on an extension of display unit 5A in the tip direction, and similarly, display unit 5D is located on an extension of display unit 5B in the tip direction. Because the tip portion of the grip 4 is formed thinner than the rear end, providing raised display units 5C and 5D makes it easier to grip the grip 4 with the palm of the hand. In other words, it is possible to prevent slippage between the palm of the hand and the grip.

[0028] Next, as another component, as shown in Figures 6 and 7, in order to improve the adhesive strength between the elastomer constituting the display unit 5 and the elastomer constituting the grip body 41, the area Sf where the display unit 5 is provided may be subjected to a treatment to roughen the outer surface 410. Alternatively, as shown in FIG. 8, grooves 410Aa-f (410Aa-c are not shown) may be formed in the same shape as the components 51a-f of the display unit 5, and the grooves 410Aa-f may be filled with the elastomer that constitutes the display unit 5 and raised, as shown in FIG. 8. Filling the grooves improves adhesive strength. Furthermore, the inner surfaces of the grooves may be subjected to the surface treatment described with reference to FIGS. 6 and 7. Furthermore, the elastomer that constitutes the grip body 41 and the elastomer that constitutes the display unit 5 may be made of different materials, but may be made of a combination of materials with particularly high adhesive strength.

[0029] As another example of the configuration of the grip 4 of the present invention, the grip body 41 does not have to be cylindrical, and the shaft connection portion 42 may be configured so that the front end of the grip 4 is screwed onto the rear end of the shaft 2. Furthermore, the body 41 of the grip 4 does not have to be made of an elastomer, and may be made of other materials, such as resins such as plastic, or wood.

[0030] In the above-described configuration, the grip 4 of the present invention has the following effect. When a player hits a golf ball with a golf club, he or she decides the address and grips the grip 4. At this time, the player decides the direction and trajectory of the ball to be hit. For example, whether to make the ball a sliced ​​trajectory or a hooked trajectory. Then, the player grips the ball in a way that suits the direction and trajectory.

[0031] Therefore, for example, in the grip 4 of the golf club of the present invention, the position where the display unit 5A is provided is set to a grip position where the ball will fly in a straight trajectory when the thumb HLt of the left hand HL is placed on this position. By using this thumb position as a reference, it becomes easy to adjust the grip position to hit a ball with a different trajectory (for example, a fade ball or a draw ball).

[0032] Furthermore, the display unit 5 can be displayed using graphics or symbols instead of letters. For example, as shown in Fig. 9, a display unit 5L having a symbol of an arrow curved to the left as a component is provided at a position corresponding to the thumb HLt position of a grip for hitting a draw ball, and similarly, a display unit 5R having a symbol of an arrow curved to the right as a component is provided at a position corresponding to the thumb HLt position of a grip for hitting a fade ball, thereby enabling the player to intuitively recognize the grip position.

[0033] Such gripping positions vary slightly depending on the player's individual physique (size and shape of the palm), shot habits, etc., so a display unit 5 is retrofitted to each grip body 41 at a position that suits the player's physique and habits. The grip 4 described above can be used as a golf club grip, as well as a baseball bat grip, a racket grip used in tennis or badminton, an umbrella handle, a car handle, or a handle for a bag or suitcase.
