Shock-absorbing pool cue grip

Shock-absorbing pool cue grip description/claims

This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/936,441, filed Jun. 20, 2007.

This invention generally relates to the field of pool cues, and more particularly to pool cues incorporating shock-absorbing devices. Even more particularly, the invention relates to such pool cues incorporating shock-absorbing devices on, at or in the grip portion of the cue.

The game of pool often requires that the player use the pool cue to deliver a sharp blow to the cue ball. This impact causes a strong vibration in the pool cue. Known grips on the handles or shafts of pool cues are often very rigid, and such grips are susceptible to transmitting vibration from the pool cue to the user's hand. These vibrations often cause an undesirable stinging sensation in the user's hand. As a result, many players experience difficulty in achieving a comfortable grip during regular play.

One attempted solution to the vibration or shock problem is to provide an annular layer of cotton material or the like beneath the grip outer layer or wrap. The drawback to this is that the material is not particularly effective in damping the unwanted vibrations and must be utilized in excessive thickness, such that the player loses feel and control of the cue. Another attempted solution, shown in U.S. Pat. No. 7,297,068 to Costain et al., tries the opposite approach by providing an underlayer to the wrap that is of greater density than wood or which involves piezoelectric elements.

It is an object of the present invention to provide a pool cue having a shock-absorbing grip that will insulate the user's fingers and hand from undesirable vibrations occurring in the pool cue. It is a further object to provide such a cue wherein the shock-absorbing grip comprises an outer wrap or cover layer of conventional material and an underlayer damping member, the underlayer comprising a polymer foam having excellent damping properties and contour form memory.

The improved pool cue comprises a handle and a shock-absorbing grip mounted thereon, wherein the grip comprises an underlayer damping member and a cover layer. The damping member is annularly disposed on the handle, preferably within a recess, and bonded to the handle to prevent slippage at the interface between the damping member and the handle. The cover layer is then wrapped around or slipped over the damping member and bonded to prevent undesired slippage or separation from the damping member. Additionally, the cover layer may be taped or otherwise attached to the handle of the pool cue.

The damping member comprises a viscoelastic polymer foam material having excellent damping characteristics and contour form memory, whereby the foam retains the contour of the depressions formed by the fingers for a short period of time after the pressure of the fingers has been relieved.

FIG. 1 is a cross section taken along the longitudinal axis of the handle of the pool cue.

FIG. 2 is a cross section taken perpendicular to the longitudinal axis of the pool cue at a location through the grip and handle.

With reference to the drawings, the invention will now be described with regard for the best mode and the preferred embodiment. In general, the invention is an improved pool cue that provides added comfort to the user. Specifically, the pool cue incorporates a grip that insulates the user's fingers and hand from the vibration resulting from the pool cue impacting the cue ball.

In one embodiment, shown in FIGS. 1 and 2, the invention generally comprises a pool cue 99 having a handle or shaft 10 and a grip 15, wherein the grip 15 comprises an underlayer damping member 20 and a cover or wrap member 30. The damping member 20 is positioned annularly on the handle 10 of the pool cue 99, typically within an annular recess formed in the outer surface of the handle 10. The damping member 20 may be in the form of a sheet member that is wrapped around the handle 10 in one or more layers until the desired thickness is reached, or the damping member 20 may be provided in the form of one or more sleeves that are drawn onto the handle 10. The cover member 30 is then positioned on the damping member 20 and the handle 10 in any manner forming a connection suitable for preventing the cover 30 from tearing or otherwise separating from the handle. The cover member 30 may be wrapped or provided as a sleeve. The cover 30 should be durable and resilient, and it may be made of rubber, leather, plastic, polyurethane, natural or synthetic woven fabric, or a variety of other synthetic materials.
