Description

Variable mass grip

The disclosure of this disclosure relates generally to a handle grip or a moving grip, and in particular to a novel and improved variable mass grip, which is particularly suitable as a grip for a shock applying device.

There are many forms of available grips available in the current market as a variety of instruments. These instruments range from hammer grips to other handle grips for sports equipment such as tennis, squash or racquetball or golf clubs. While the present invention is particularly well suited as a golf club grip and is described herein with reference to this example, it will be readily apparent that the present invention is not intended to be limited to golf grips but can be extended to any sport grip or shock. Apply the handle grip of the appliance.

Initially, the golf club grip was mainly made up of leather wound around a handle. Thereafter, molded rubber grips have become versatile and have been widely used until now. A recent change in molded rubber grips uses a rubber bushing or a sleeve on the handle and is spirally wound around the grip sleeve with leather or synthetic leather to achieve a softer hand feel. Current grips are made from a variety of materials and combinations.

There is still a need for an improved variable mass grip that applies or receives an impact or strength to or from a shock applying device and provides a varying cushion. This grip should provide a stable grip with a slight sliding or almost no slip, strong torsion resistance and strong impact absorption. At the same time, there is a swing weight control of the enhanced appliance to achieve a more effective control of one of the appliances. swing Heavy object control, handle rigidity, telescopic control and cushioning damping are just some of the important elements that enhance the impact from the appliance. The concept of adapting a variable mass to a grip provides the user with multiple choices to improve their athletic strategy, or to make the job simpler by using and performing better tools.

Accordingly, it may be desirable to have a variable mass grip that allows the user to select the handle or handle that properly assembles and feels the shock applying appliance or appliance to meet the user's needs in a given application.

The present invention describes an improved end cap for a variable mass grip. The end cap includes a portion having a generally cylindrical member at one end to form an upper portion of the end cap. A tubular portion is attached to one side of the cylindrical member cone in a direction away from the cylindrical direction. A tubular portion adjacent the cylindrical member has a first annular groove located on an outer surface thereof and a second annular groove adjacent the first annular groove at an inner surface thereof. The tubular portion is configured to receive a selected mass and is disposed within a hollow body that is sized and shaped to be mounted to a handle of an appliance. The present invention further describes how the improved variable mass grip saves manufacturing costs in manufacturing and designing the grip and reducing inventory costs.

Various novel features which are characteristic of the invention are pointed out in the appended claims and are part of the invention. For a more in-depth understanding and by using the operational advantages that can be achieved, reference is made to the drawings and descriptive content.

Please refer to the drawings, which are not intended to limit the invention, and in several views The same component numbers are used to designate the same or similar features, and reference is first made in detail to Figure 1, which shows a golf club generally designated 10. The golf club 10 includes a golf club grip 12, a handle or handle 14, and a club head 16, and is an example of a shock applying device. The term "vibration applicator" is used herein to mean a sports implement and appliance that is used to impact, impact or apply a force on a body or an implement. Tennis rackets, squash rackets, short racquet racquets, lacrosse grips, fishing rod handles, bicycle handlebars, motorcycle handles and baseball grips are only a small part of the example used in the term "vibration applicator". Of course, there are some other appliances, and even more athletics are expected to be improved within the scope of this disclosure. The term "vibration applicator" is also meant to include, but is not limited to, a handle such as a hammer handle or a screwdriver handle.

Returning to Figure 1, the golf club grip 10 is known in the art as a slipper type golf club. The term "sleeve" is used herein to refer to a grip that is used to slide over a handle or handle 12 and to be secured thereto. The grip is slid over a golf club handle or handle by an adhesive, tape or the like and secured thereto. Methods of making and placing such grips on a golf club grip are well known in the art and need not be further explained herein. It is known in the art that the sleeve golf club grip is viable in a variety of shapes, configurations and materials that are widely used in industry. Current golf club grips are made of an elastic material such as a rubber composition, a synthetic plastic or rubber, a thermoplastic material, and may contain fibers or thin wires embedded therein. Although the content of the present disclosure is particularly suitable as a golf club grip, and This is illustrated by way of example, but the invention is not intended to be limited solely to golf grips as previously mentioned, and can be used with handle grips of most other types of shock applying implements.

Referring next to Fig. 2, there is shown an improved design of the end cap of the variable mass grip in accordance with the present disclosure, generally designated 20. The end cap 20 has an engagement element 22 at one end, which may also be referred to as the engagement end of the grip. The engagement element 22 forms an upper portion of the end cap 20. However, the engaging element 22 is preferably a generally cylindrical member in shape, but it is contemplated that the engaging element 22 may comprise other forms including, but not limited to, elliptical, hexagonal, octagonal, square or various other Shape for the grip. The end cap 20 further includes a tubular portion 24 that is coupled to one side of the lower portion of the engagement member 22 that forms one of the end caps 20. The tubular portion 24 is progressively proximal to the head 16 in a direction away from the engaging element 22. The tubular portion 24 is hollow and in one embodiment has a diameter that is decreasing away from the engagement element 22. It should be understood that the tubular portion 24 may be comprised of more than one diameter in other embodiments. At least the first annular groove 30 is disposed on an outer surface of the tubular portion 24 adjacent the engagement element 22. Other embodiments provide a plurality of annular grooves 30. As further shown in another embodiment of Fig. 8, the tubular portion 24 may be threaded through the threaded insert fitting portion 31 adjacent to the engaging member 22 and extending to a desired length. As shown in Figure 2, the tubular portion 24 is configured to receive a selected mass which may be one of the anti-vibration plugs 26 as shown in Figure 2, a dashed portion as shown in Figure 3 or a solid portion as shown in Figure 4. The method of pre-determining the weight 28, or a combination of the two, will be described later in more detail.

In Figures 5 and 6, a hollow body that forms the rest of the grip is shown Part 32. The body 32 is sized to be held at one end of the handle or handle 14. At the top is intended to serve as the engagement end of the grip, the body 32 has a tapered recess 34 that conforms to the tubular portion 24 in size and shape and is configured to receive the tubular portion 24 there. The tubular portion 24 is employed to fit snugly within the recess 34. The recess 34 further includes at least one annular ridge 36 to engage the first annular recess 30 as mentioned above to secure the end cap 20 over the body 32 by a mechanical traction engagement. Other embodiments may include two or more ridges 36 that join two or more annular grooves 30. As further shown in FIG. 9, an inner threaded portion 33 may be substituted for the threaded insert fitting portion 31 of the alternate embodiment of the tubular portion 24 of the end cap 20 in place of the ridge 36.

Referring to FIG. 4, the weight 28 is shown disposed within the end cap 20 in a manner that the weight extends from the tubular portion 24 to the hollow portion of an engagement member 22. The passage 29 extends through the center of the engagement element 22 and the end cap continues through the weight 28 for placing and holding the weight 28 during casting of the end cap 20. The weight 28 is preferably a tungsten material having a weight ranging from about 1 gram to about 1500 gram depending on the user and application. More preferably, the weight may range from about 10 grams to about 40 grams. The weight 28 is wrapped within the end cap 29 during casting via the end cap 20. An O-ring 38 engages a second annular groove 40 located adjacent one of the interior surfaces of the tubular portion 24 of the first annular groove 30, but provides an end cap 20 to the opposite side of the tubular portion 24 (i.e., at the interior surface) to The handle 14 is an auxiliary traction component.

As mentioned previously, the design of the improved end cap 20 of the present invention has the advantage of selectively using an anti-vibration plug 26 that is bonded to the weight 28 as shown in FIG. 2, or A separate plug with no weight 28. It will be immediately appreciated that the anti-vibration plug 26 can contain its own weight contained therein if desired, and its means within the hollow handle 14 can be of any length. By adjusting the length of the anti-vibration plug 26, the user can select the amount of anti-vibration as needed. The use of the anti-vibration plug 26 and a separate weight 28 provides the advantage that the anti-vibration plug 26 can be made of more resilient material for shock absorption and shock absorption. The anti-vibration plug 26 is preferably cylindrical in shape and has at least one O-ring 42, preferably two O-rings 42, 44 disposed away from an opposite end of the end cap 20. The O-rings 42, 44 are sized to fit snugly into the handle 14 and act as a shock absorber and shock absorber, as if the remainder of the anti-vibration plug 26 is transmitted via waves. End cap 20, body 32 and anti-vibration plug 26 having O-rings 38, 42, 44 are preferably fabricated from an elastomeric or thermoplastic material that is most suitable for this application.

The body 32 can comprise one or more layers of rubber, elastomeric or thermoplastic material, or a composite of such materials in a configuration to supply a varying durometer value. A durometer value or grade is an international standard for determining the hardness of rubber, plastic or other non-metallic materials. Hardness values or grades are described in the ASTM D2240 specification of the American Society for Testing and Materials. For example, in one embodiment, an inner surface 46 of the body 32 secured to the handle 14 has a value of from about 25 to about 50 Shore A hardness. The outer surface 48 of the body 32 may comprise a value of preferably from about 25 to about 90 Shore A durometer, or any combination of standards to provide a good friction of the outer surface grip and a contact feel with an internal cross section. ready.

The replacement of golf grips is quite common in the golf industry, and the replacement of golf grips is well known. Improved end of the disclosure The cover 20 and body 32 allow the user to select the most suitable weight, anti-vibration plug and total mass for a given application. The ability to disassemble and replace the end cap 20 to fill more or less weights, more or less anti-vibration plugs, or both, so that even the body 32 is secured to the handle 14 during adjustment It is then convenient to move flexibly. This flexibility allows the user to adjust the appliance according to its own unique sensation. Beneficially, the body 32 can be placed on the handle 14 in a known manner in which the grip is replaced, or the end cap 20 and the body 32 can be placed on the handle 14 as a single grip, and then can be Replace the end cap 20. If the grip does not have its own unique feel, the user has the option of replacing the end cap even after the grip has been placed on the handle.

As a result, since the end cap 20 and the body 32 are replaceable, the number of inventory is also greatly reduced, whereby the production cost is also significantly reduced due to the smaller inventory.
