Background Art

[0002] Recently, due to the novel coronavirus, the number of people enjoying golf has increased. To improve at golf, it is necessary to select a golf club and putter of an optimal length according to one's height and build.

[0003] The length of the putter is selected according to height and build, but the grip attached to the tip of the shaft is fixed so that the length of the putter becomes 33 inches or 34 inches. If you want a putter of a different length, it will be a special order. Since a special order requires processing in a workshop, it will cost a high price. Also, even if it is manufactured by special order, the grip is fixed, so the user cannot adjust the length of the putter by themselves. On the other hand, when going out on the course, there are times when you may want to use a putter of a different length depending on the weather, the condition of the grass, or your mood on that day. Therefore, golfers usually prepare multiple putters of different lengths, which costs a lot of money.

[0004] Focusing on the above, the present invention provides a putter - that allows a golfer to change the attachment position of the grip and adjust the length of the putter.

Patent Document 1

Patent Document 2

[0006] Regarding the above problem, Players themselves An invention of a golf club (putter) whose length can be adjusted is proposed in the above-mentioned Patent Document 1. To explain in more detail, The invention described in Patent Document 1 is, A plug body 2 is provided at the cylindrical upper end 1a of the shaft 1, a long threaded rod 3 is screwed into a threaded hole 2a drilled in the plug body 2, and an engaging member 4 is formed at the tip of the threaded rod 3. The grip 13 is positioned by engaging the separately provided handle 22 with the engaging member 4 and rotating it in forward and reverse directions.

[0007] In this way, the length can be adjusted, but to adjust the length of the club, a special screw rod rotating tool B must be prepared. While club length adjustments are usually made beforehand, there are times when you might want to adjust them during play depending on the condition of the green or the weather. In the invention described in Patent Document 1, if the dedicated handle is forgotten, adjustment cannot be made, meaning that play must be continued without adjustment, resulting in a poor score.

[0008] Furthermore, since the screw rod 3 must be rotated many times to make adjustments, it cannot be adjusted quickly. Furthermore, the invention described in Patent Document 1 has a complex structure because it requires forming a tip portion (rotation-preventing means) 1a at the tip of the shaft 1 and incorporating multiple components therein.

[0009] In contrast to the aforementioned invention with a complex configuration involving a large number of parts, an invention with a simpler configuration involving fewer parts is proposed in Patent Document 2 (US Patent Application Publication No. 2021 / 0154542, "GRIP FOR A HANDLE ON A GOLF CLUB"). Patent Document 2 has a simple configuration with fewer parts, and the problems of Patent Document 1 are resolved, but it has a new problem when adjusting the length.

[0010] Furthermore, the specification of Patent Document 2 describes forming the grip out of rubber material and utilizing its own elastic force The golf clubs to be attached to the shaft (HANDLE) are listed. In this configuration, changing the grip's mounting position and adjusting its length requires a significant force to overcome the frictional force caused by its elasticity. Therefore, for golfers with less strength, changing the mounting position and adjusting the length can be extremely difficult.

[0011] Focusing on the above, the present invention The golfer himself can quickly and easily adjust the length of the putter without a dedicated tool, The adjustment does not require much force. and further aims to provide a light putter composed of a minimum number of parts.

Means for Solving the Problems

[0012] The object of the present invention is achieved by a shaft made of carbon, steel, aluminum alloy or wood, and the shaft of the putter itself where a grip is directly attached to the tip portion without any other members intervening between the shaft itself and the grip. A putter having a grip that allows fingers to fit the grip when holding it, and having a grip made of a soft material such as rubber or / or a hard or soft material such as rubber and / or the said soft material so that fingers can fit the grip when holding it, and having multiple screws that do not require tools such as a screwdriver or special tools to fasten and loosen the grip's mounting position and the length or height of the putter, leaving a small gap between the two ends of the grip, the putter being characterized by having all of the following (1) to (3). (1) The screws are not ordinary screws that require tools such as screwdrivers, nor do they require any special tools such as screwdrivers, and the adjustment can be made quickly and easily without any special tools, and the screws have a groove formed in the head that can be engaged with a coin such as a 10 yen coin, so that the adjustment can be made quickly and easily without any special tools such as screwdrivers. (2) By rotating and tightening multiple screws, the holes in the grip are expanded and contracted, causing the grip to move away from the shaft, loosen and tighten, and then move, adjust and fix the grip to the desired mounting position, thereby changing the mounting position of the grip and the length or height of the putter. (3) The grip has a hole for inserting a shaft that runs through from the top to the bottom of the grip, and both ends of the grip are formed with a small gap below the hole, and multiple screws fasten the ends of the grip together, creating a tightened state where the ends of the grip are in contact and the gap is eliminated. is achieved.

Effects of the Invention

[0013] By the above means, the present invention enables a golfer to quickly and easily adjust the length of the putter without a dedicated tool, The adjustment does not require much force. and further has the effect of being able to provide a light putter composed of a minimum number of parts.

Modes for Carrying Out the Invention

[0015] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 4. In Figure 1, P represents the putter body. The putter body P consists of a shaft 1 made of carbon, steel, aluminum alloy, or wood, a grip 2 inserted into the upper end of the shaft 1, and a putter head 3 fixed to the lower end of the shaft 1. The putter head 3 is typically mounted diagonally to the shaft 1. Additionally, although not shown in the diagram, a cap is attached to the upper end of shaft 1 to prevent finger injury if touched.

[0016] The grip 2 is molded from soft rubber or synthetic resin so that the fingers fit comfortably when gripped, and a finger-retaining surface 21 is formed around the perimeter as shown in Figure 2.

[0017] Furthermore, as shown in Figure 2, the grip 2 has a hole 22 through which the shaft 1 passes, and peripheral ends 23 and 24 are formed below the hole 22, leaving a small gap S. Figure 2 also shows the state in the tightened state described later, where the peripheral ends 23 and 24 are in contact and the gap S is eliminated. 4 is a wing nut that fastens the circumferential ends 23 and 24 together. In one embodiment, three grips 2 are provided so that they can be evenly attached to the shaft 1.

[0018] When playing privately and you want to change the length (height) of the putter, simply rotate the wing nut 4 to change the position of the grip 2 up or down, move the grip 2 to the desired position (see the dotted line in Figure 1), and fix it in place. In other words, no tools are required to adjust the length of the putter. For those who find the wing nut #4 to be interfering with their putting motion, it can be replaced with a regular screw, but this requires tools such as a screwdriver. If a groove is formed in the head of the screw so that it can engage with a coin such as a 10 yen coin, A dedicated handle such as the one described in Patent Document 1. No tools are needed.

[0019] 5 is a washer that fits onto the wing nut, and its purpose is to prevent damage to the area around the grip 2 when the wing nut 4 is screwed in. If grip 2 is hard, or if it is soft and the area around the screw is molded to be thicker than the rest, washer 5 may be omitted.

[0020] In the configuration of the above-described embodiment of the invention, a method for adjusting the length (height) of the putter will be explained. To change the length of the putter, loosen the wing nut 4 by turning it counterclockwise. This will expand the hole 22 in the grip 2, causing the grip 2 to move slightly away from the shaft 2. Therefore, the grip 2 is released from its tightened position relative to the shaft 1, and can be moved quickly and instantaneously to the desired position without applying any force to the grip 2.

[0021] Then, by changing the mounting position of the grip 2 considering your height and the condition of the green, and rotating the wing nut 4 to the right at the changed position (dotted line in Figure 1), the hole 22 will shrink, and the grip 2 can be tightened and attached to the shaft 1.

[0022] In this way, by moving the grip 2 to the desired position and tightening the wing nut 4, the grip 2 is securely attached to the shaft 1, and the adjustment of the grip 2's mounting position on the putter is complete. Furthermore, according to the configuration of the above embodiment, it is possible to make fine adjustments and obtain a putter of the optimal length (height), which contributes to score making. Also, a screwdriver and the aforementioned tools are used to adjust the mounting position of the grip 2. Patent Document 1 The special tools listed are not necessary.

[0023] As described above, the present invention is The golfer himself The length of the putter can be adjusted quickly and easily without the need for special tools. The adjustment does not require much force. Furthermore, we were able to provide a lightweight putter composed of the minimum number of parts. [Explanation of symbols]
