Method of making a weighted golf swing trainer

Abstract

A method of making at least two types of weighted golf swing trainers. In a first type of trainer club, a lower section of a hollow golf shaft is filled within a first type of particle and a flowable material. A barrier is then by created to keep the flowable material and the first type of particle in the lower section. A second type of particle and a compressible epoxy resin is placed into an upper section of the golf shaft so that the resin cures to surround the second type of particles. A method of making a second type of trainer club where flowable materials are impermissible. Such second club is made in a similar manner as the first type with the exception that the first type of particle and flowable material are mixed with compressible epoxy resin and placed into the lower section of the golf shaft.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims priority to and is a continuation-in-part of utility patent application Ser. No. 10 / 850,079 filed on May 19, 2004, and hereby claims the benefit thereof.BACKGROUND OF THE INVENTION [0002] The present invention relates to golf swing practice equipment and a method of making the same. [0003] There are many golf swing trainers in the marketplace which claim to help golfers have a correct swing on a consistent basis. Exemplary of such golf swing trainers is that described in Sorenson U.S. Pat. No. 5,582,407. [0004] Also, more than one year ago I invented and sold the golf swing trainer described in U.S. Provisional Application Ser. No. 60 / 384,502 filed May 29, 2002. [0005] Existing golf swing trainers suffer from one or more disadvantages, including: [0006] Inability to actually hit a golf ball with the trainer to provide feedback to the golfer as to the effectiveness of the golfer's swing. [0007] Failure to meet USG...

AI Technical Summary

Benefits of technology

[0016] In one version of the invention, the tungsten powder can move during the swing, to help the user swing properly. This can be effected by having the tungsten powder be present in only a portion of the lower section.

[0018] Another benefit of using the improved golf swing trainer club is that proper and consistent use of the trainer club promotes building muscles specifically exerted when a user swings the club in the proper swing plane. These muscles, the so-called “golf muscles,” include muscles surrounding the arms, hips and legs. Of these muscles, there are those generally known as “slow-twitch” muscles that are used primarily when the muscle must support a large amount of weight for an extended period of time. An example of these muscles are those exerted when curling weights with the arms. There are also muscles known as “fast-twitch” muscles that are used for quick bursts of power, such as the leg muscles exerted by sprinting runners. Advantageously, the golf swing trainer made according to the present invention helps build the “fast-twitch” muscles used in the golf swing. By promoting users to swing the club in the proper swing plane, the fast-twitch muscles typically used when swinging in this plane are exercised. Incorporating a series of exercises with the club can yield significant muscle-building benefits that are targeted to the “fast-twitch” muscles, yielding a significant increase in swing speed. Moreover, a unique advantage in building “fast-twitch” muscles with the golf swing trainer made according to the present invention is that the user, by increasing club head or swing speed, in turn receives a dramatic increase in distance, which is a long-felt need.

Problems solved by technology

Existing golf swing trainers suffer from one or more disadvantages, including: Inability to actually hit a golf ball with the trainer to provide feedback to the golfer as to the effectiveness of the golfer's swing.

Failure to meet USGA® compliant requirements for on course use.

Lack of the “feel” of an actual golf club.

Although the use of flowable materials in golf clubs has been used in the past, such use of flowable materials appear to be limited to use in standard golf clubs, specifically those which aim to provide a user with selectable adjustments while on the golf course.

Such a design fails to disclose a flowable material limited to the lower section of the golf club.

Such technology is not applicable to disposing two different particles in the shaft of a golf club since sweet spots may not be altered by modifications to the shaft.

Such alteration of the balance point is typically disadvantageous in golf swing trainers since it is the preset placement of the balance point that provides part of the advantageous training features.
