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

The present invention is a golf swing trainer that helps users improve their swing by using a shaft with high-density particles and tungsten powder. The trainer can be used as a regular golf club and has the feel of one. The filling material can include urethane resin, and there is no barrier between the two sections to prevent the particles from moving during a swing. The trainer promotes the use of fast-twitch muscles and helps build muscles that are used when swinging in the proper swing plane. The user receives a dramatic increase in distance by increasing club head or swing speed.

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.
