Abstract
A shaft handle comprises a tube body and a ribbon covering tube body. The ribbon comprises a flexible layer and an anti-slipping layer attached on the flexible layer. The thickness of the anti-slipping layer is smaller than that of the flexible layer. The total thickness of the ribbon is about 1.2 to about 2.4 cm.
Description
- The invention relates to a shaft handle for use in a golf club shaft. More, specifically, the invention relates to a shaft handle for use in a golf club shaft, which is lightweight and can absorb external vibration.
- As shown in FIG. 1, a conventional
golf club shaft 1 usually is provided with atube body 2 made of natural rubber or synthetic rubber for grip by the user. Due to the weight of thetube body 2, made of natural rubber or synthetic rubber, the weight distribution between the shaft head and the handle is not appropriate. In order to meet the lightweight demand for the current golf club shaft, it is required to reduce the weight of the shaft handle. - One approach has been proposed by which wood flours are added into the rubber material, and the rubber material is thermally pressed to form coarse surface thereon. If the coarse surface is made finer with sufficient friction, the processing cost is greatly increased.
- Another approach has been proposed by which a
ribbon 3 made of natural feather or synthetic feather, such as PU, is applied on thetube body 2, as shown in FIG. 2. When theribbon 3 is made of PU, its use is disadvantageous in high humidity conditions such as rainy day or substantial sweating, because the friction effect produced by theribbon 3 is reduced. Furthermore, PU is not wear-resistant. When theribbon 3 is made of natural feather, in addition to its consequent high production cost, theribbon 3 further produces unpleasant odor and is hardened after long-term use. - As illustrated in FIG. 3, another type of conventional golf club handle includes a
cap 1 that is arranged at the end of the golf club handle, and agrip tape 2 further is wound around the golf club handle. This type of construction usually needs two manufacturing stages, and is not economical, and further increases the assembly time. When the user wants to change the grip tape, he/she first has to tightly insert thecap 1 at the handle end, and then wind the grip tape around the handle. For users who are not familiar with this manual operation, uniformly and stably winding the grip tape may be troublesome. This conventional construction therefore is not practically convenient, and the change of grip tape does not represent an economical solution. - Shocks or vibrations produced when the golf club hits the golf ball are usually absorbed by the shaft handle. Increasing a thickness of the handle increases the vibration-absorbing ability of the handle, and further increases the weight and the outer diameter of the handle, which adversely affects the use of the golf club shaft.
- Therefore, there is a need to provide a shaft handle that can improve the vibration-absorbing ability, and have a reduced weight.
- Accordingly, it is an object of the invention to provide a shaft handle suitable for use with a golf club shaft. The shaft handle comprises a tube body and a ribbon covering the tube body. The tube body includes a first flange and a second flange at opposite ends thereof. The ribbon comprises a flexible layer and an anti-slipping layer attached on the flexible layer. With the shaft handle of the invention, improved grip ability, reduced weight and increased vibration-absorbing effect are obtained.
- To provide a further understanding of the invention, the following detailed description illustrates embodiments and examples of the invention, this detailed description being provided only for illustration of the invention.
- The drawings included herein provide a further understanding of the invention. A brief introduction of the drawings is as follows:

- FIG. 2 is a perspective view of a conventional shaft handle around which a ribbon is wound;
- FIG. 3 is a perspective view of another type of conventional shaft handle;
- FIG. 4 is an exploded view of a golf club shaft provided with a shaft handle according to an embodiment of the invention;
- FIG. 5 is a perspective view of a golf club shaft provided with a shaft handle according to an embodiment of the invention;
- FIG. 6A, FIG. 6B and FIG. 6C show a process flow to manufacture a shaft handle according to a first embodiment of the invention;
- FIG. 7A, FIG. 7B, FIG. 7C and FIG. 7D show another process flow to manufacture a shaft handle according to a second embodiment of the invention; and
- FIG. 8 is a schematic view illustrating an implementation of the shaft handle of the invention in a tennis racket.
- Wherever possible in the following description, like reference numerals will refer to like elements and parts unless otherwise illustrated.
- With reference to FIG. 4, FIG. 5 and FIG. 6B, a vibration-absorbing handle includes a
tube body 10, aflexible layer 20 and aanti-slipping layer 30. Thetube body 10 includes ahollow rod 13 for receiving ahandle portion 4 of agolf club shaft 1 therein. Afirst flange 11 and asecond flange 12 that have larger diameters than thehollow rod 13 are respectively provided at ends of thehollow rod 13. An example of the material for thetube body 10 includes a natural rubber or synthetic rubber that has good tensile elongation. - The
flexible layer 20 is wound around thehollow rod 13. Theflexible layer 20 is made of a material with low density and high elastic constant. An example of the material for theflexible layer 20 includes polyurethans (PU), polyethylenes (PE) or ethyl vinyl acrylate foams. Other materials that are lightweight and can absorb vibration are also suitable to form theflexible layer 20. In this embodiment, soft polyethylene is used. - The
anti-slipping layer 30 is wound around theflexible layer 20. One end of theanti-slipping layer 30 is secured at thesecond flange 12. Theanti-slipping layer 30 has a thickness smaller than theflexible layer 20. The material for theanti-slipping layer 30 can be rubber, for example. The total thickness of theanti-slipping layer 30 and theflexible layer 20 is about 1.2 cm to about 2.4 cm. - The
flexible layer 20 and theanti-slipping layer 30 are wound around thehollow rod 13, so that the total thickness of the shaft handle is not substantially increased, and a user can more easily hold the shaft handle. Furthermore, the total thickness of the shaft handle is designed according to the size of the user's palm and the difference between the diameter of thehollow rod 13 and theflanges flexible layer 20 and theanti-slipping layer 30 should be relatively smaller. On other hand, when the user's palm is large, the total thickness of theflexible layer 20 and theanti-slipping layer 30 should be relatively larger. Furthermore, the total thickness of theflexible layer 20 and theanti-slipping layer 30 can be designed in manner that the diameter of thehollow rod 13 is gradually increased from one end to the other end to provide optimal grip for the user. - With reference to FIG. 6A to FIG. 6C, the shaft handle includes a
tube body 10, aflexible layer 20 and ananti-slipping layer 30. First, at one end of thetube body 10 is formed afirst flange 11, and the other end of thetube body 10 is connected to asecond flange 12 that has a bell shape, as shown in FIG. 6A. Theflexible layer 20 is attached to theanti-slipping layer 30 by an adhesive 21 to form aribbon 40. Theribbon 40 is wound around thehollow rod 13 from thefirst flange 11 toward thesecond flange 12, as shown in FIG. 6B. Theribbon 40 is collected at the end 44 of thehollow rod 13 where thesecond flange 12 is seated. Then, the second flange encapsulates the portion of theribbon 40 at theend 14 of thehollow rod 13, as shown in FIG. 6C. The shaft handle is thus accomplished. - Reference now is made to FIG. 7A through FIG. 7D to describe a shaft handle according to another embodiment of the invention. Similar to the previous embodiments, the shaft handle includes the
tube body 10, theflexible layer 20 and theanti-slipping layer 30. Thetube body 10 respectively terminates in afirst flange 11 at one end and a bell shape at an opposite end, as shown in FIG. 7A. Theflexible layer 20, formed in a tape, is adhered on thehollow rod 13 of thetube body 10, as shown in FIG. 7B. Theanti-slipping layer 30 is formed as aribbon 40 is wound around the tube body over theflexible layer 20 from thefirst flange 11 toward thesecond flange 12, as shown in FIG. 7C. Theanti-slipping layer 30 is collected at theend 14 of thehollow rod 13 where thesecond flange 12 is seated. Then, the bell-shapedsecond flange 12 encapsulates the portion of theribbon 40 at theend 14 of thehollow rod 13 to fixedly attach theanti-slipping layer 30. The vibration-absorbing shaft handle of the invention may be suitable for various types of games racket such as tennis rackets (as shown in FIG. 8), badminton rackets, etc. - It should be apparent to those skilled in the art that the above description is only illustrative of specific embodiments and examples of the invention. The invention should therefore cover various modifications and variations made to the herein-described structure and operations of the invention, provided they fall within the scope of the invention as defined in the following appended claims
