Abstract

Abstract A golf training device comprising, in combination: a golf club having a shaft with a club head portion situated on a first end thereof and an elastomeric handle positioned on a second end thereof, the club further having a cylindrical axial bore formed in the second end thereof and which is accessible from the second end, wherein the bore is of a predetermined length and diameter; and a laser emitting device including a first mounting portion with a cylindrical configuration having a size, length and shape consistent with that of said bore for being releasably fixed therein, and a second portion integrally formed in axial relation with the first portion with a cylindrical configuration along a majority of its extent and a frusto-conical configuration along the remainder of its extent, the frusto-conical extent including a flange defined by a radially extending portion extending laterally beyond and adjacent the first portion of the device and a beveled outer surface portion extending from the outer periphery of the radially extending portion to a point a distance away from the first portion which is a small fraction of the length of the second portion. The length of the second portion is between 50% and 75% of the predetermined length. The total length of the laser emitting device is between 3 and 6 inches. The radial portion of the flange is flush with the second of the club when the laser emitting device is secured in the bore.

A new and improved laser golf training device comprising, in combination: a golf club having a shaft with a club head portion situated on a first end thereof and an elastomeric handle positioned on a second end thereof, the club further having a cylindrical axial bore formed in the second end thereof and which is accessible from the second end, wherein the bore is of a predetermined length and diameter; and a laser emitting device including a first mounting portion with a cylindrical configuration having a size, length and shape consistent with that of said bore for being releasably fixed therein and a second portion integrally formed in axial relation with the first portion with a cylindrical configuration along a majority of its extent and a frusto-conical configuration along the remainder of its extent, the frusto-conical extent including a flange integrally formed therewith and defined by a radially extending portion extending laterally beyond and adjacent the first portion of the device and a beveled outer surface portion extending from the outer periphery of the radially extending portion to a point a distance away from the first portion which is a minor fraction of the length of the second portion, wherein the length of the second portion is between 50% and 75% of said predetermined length, the laser emitting device further having a disk-shaped lens formed on an end of the second portion thereof opposite the flange and an actuator switch positioned on a central extent of the second portion having a first orientation for transmitting an activation signal and a second orientation for transmitting a deactivation signal, the laser emitting device adapted to emit a laser through the lens which resides along an axis of the device upon the receipt of the activation signal, wherein the total length of the laser emitting device is between 3 and 6 inches; whereby the first portion of the laser emitting device may be inserted within the bore of the golf club with the radial portion of the flange flush with the second end thereof for allowing a user to track a plane of the user's swing.
