Abstract
Abstract A golf swing training and exercising device comprises a vertical tubular member having a telescopic complementary tubular member for adjusting the height of the device, a tubular swing arm having another tubular member and a complementary member insertable therein to adjust the length of a swing arm, electrical signaling apparatus comprising a plurality of spaced switches which are in closed position when in contact with a cam housed on the swing arm. Certain signals are actuated by forward and backward movement of a grip, and other signals are actuated by rotary movement of the grip. Some signals indicate when a proper address, swing and follow through are made. A certain different set of signals indicate when a "fat" or "light" hit is made during a swing. The device, optionally, has a head restraining device which has an electrical switch that is adjustable for an allowable degree of head movement before it is closed to activate a signal indicating excessive head movement. The training and exercising device can be used with or without a golf club and with or without a golf ball or a practice substitute for a golf ball. A variable tension can be applied on a braking system to exercise and improve the strength of muscles employed during the swing. The device may also include a weight shift signal element wherein electrical switches are operated upon predetermined and timely weight shift from one foot to the other.

Claims Analysis
Total Claims: 26
Claim 1
Independent Claim
203 words
A mechanism useful for improving a golf swing and for exercising muscles used in said swing comprising: (a) a base member on which the mechanism is supported, (b) an upright member attached at the base, said upright member having a rigidly mounted post attached at its top to which post a swing arm and a brake adjustable as to tension are attached, (c) a signal pack on said swing arm having a rod carrying a cam said swing arm having a plurality of switches which are closeable by movement of said cam, each of said switches when closed activates a separate signal which individually can indicate (1) a movement of a simulated club toward and away from a golfer and (2) rotary movement of the wrists, said switches being connected to a source of electrical current said pack having at its distal end (d) a grip which is movable forwardly and backwardly to move said cam for closing certain of said switches and thereby activate electrical signal means, said grip also being movable laterally to simulate wrist action and to activate signals different from the signals activated by forward and backward movement, thereby denoting the position of a club face during a swing.
Claim 2
Dependent Claim
203 words
A mechanism useful for improving a golf swing and for exercising muscles used in said swing comprising: (a) a base member on which the mechanism is supported, (b) an upright member attached at the base, said upright member having a rigidly mounted post attached at its top to which post a swing arm and a brake adjustable as to tension are attached, (c) a signal pack on said swing arm having a rod carrying a cam said swing arm having a plurality of switches which are closeable by movement of said cam, each of said switches when closed activates a separate signal which individually can indicate (1) a movement of a simulated club toward and away from a golfer and (2) rotary movement of the wrists, said switches being connected to a source of electrical current said pack having at its distal end (d) a grip which is movable forwardly and backwardly to move said cam for closing certain of said switches and thereby activate electrical signal means, said grip also being movable laterally to simulate wrist action and to activate signals different from the signals activated by forward and backward movement, thereby denoting the position of a club face during a swing.
Claim 3
Dependent Claim
15 words
The mechanism of claim 1 in which the upright member is adjustable as to height.
Claim 4
Dependent Claim
21 words
The mechanism of claim 1 in which the swing arm is adjustable as to length to provide an effective inside/outside swing.
Claim 5
Dependent Claim
19 words
The mechanism of claim 1 which has a head restraining member connected by a rod to said upright member.
Claim 6
Dependent Claim
20 words
The mechanisms of claim 4 which has an electrical signal operable by movement of the head beyond a predetermined degree.
Claim 7
Dependent Claim
40 words
The mechanism of claim 1 in which the brake comprises a rotatable drum having a race and a brake band in the form of an arc of an ellipse along its long axis, said brake being adjustable as to tension.
Claim 8
Dependent Claim
33 words
The mechanism of claim 1 in which the base member has a plurality of wheels attached thereto for easy portability and a plurality of leveling jacks to adjust the mechanisms on uneven surfaces.
Claim 9
Dependent Claim

The mechanism of claim 1 in which the base has a set of foot placement markings for the user.
Claim 10
Dependent Claim
72 words
The mechanism of claim 1 in combination with a weight shift signal element comprising a pivotal foot pad, an adjustable spring balanced mechanism which operates electrical switches upon predetermined and timely weight shift from one foot to the other, and in which the electrical circuit can be placed in series with other signals thereby precluding the operations of any signal unless the weight shift has been of the proper magnitude and time.
