Abstract
Abstract An apparatus for allowing a golfer to practice his club swings indoors or out. The apparatus is equipped with mechanical indicating devices that tell a golfer at a glance if his swing was correct. These indicators, which are held in place by magnets on a steel plate and have means for threadedly adjusting their overall height, can be precisely positioned to take into account variations between different golfers and between different driving clubs or putting irons. The tops of the indicators are formed of a highly springy, resilient material which vibrates for an extended period of time after being hit or even brushed by a club. A good swing can be easily recognized as one after which none of these fault-finding indicators are moving.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
155 words
A golf training device adapted to support a golf ball comprising: (a) a base having a cavity formed therein, and at least one plate formed of ferromagnetic material being disposed within the cavity; said plate being recessed below the top surface of said base; and (b) a plurality of indicators, means utilizing magnetic forces for detachably mounting each indicator upon the upper surface of the plate in any one of an infinite variety of positions, each indicator having a vibratory member connected to the mounting means, the indicators being positioned on the plate proximate a substantial portion of an arc described by the head of a golf club at points before, during, and after the club contacts the ball, so that when a true swing is imparted to the head of the club, none of the indicators is set into vibratory motion; the mounting means simply moving with the head when the indicator is hit.
Claim 2
Dependent Claim
155 words
A golf training device adapted to support a golf ball comprising: (a) a base having a cavity formed therein, and at least one plate formed of ferromagnetic material being disposed within the cavity; said plate being recessed below the top surface of said base; and (b) a plurality of indicators, means utilizing magnetic forces for detachably mounting each indicator upon the upper surface of the plate in any one of an infinite variety of positions, each indicator having a vibratory member connected to the mounting means, the indicators being positioned on the plate proximate a substantial portion of an arc described by the head of a golf club at points before, during, and after the club contacts the ball, so that when a true swing is imparted to the head of the club, none of the indicators is set into vibratory motion; the mounting means simply moving with the head when the indicator is hit.
Claim 3
Dependent Claim
52 words
A golf training device according to claim 1 wherein the vibratory member is further characterized as being formed of a springy material that is set into vibratory motion by a slight brush of the golf club; the vibratory motion being of sufficient amplitude and duration that it could be easily detected visually.
Claim 4
Dependent Claim
45 words
A golf training device according to claim 1 wherein the mounting means further comprises a vertical column and means for adjusting the overall height of each indicator, the adjusting means including the vertical column having internal threads which are threadedly engageable with the vibratory member.
Claim 5
Dependent Claim
130 words
A golf training device adapted to support a golf ball comprising a base plate made of a material that can be subjected to magnetic forces; indicators which are held to the base plate by these magnetic forces, each of said indicators having a vibratory element which can be set into vibratory motion of sufficient amplitude and duration to signal the user visually that his club has come into contact with the indicator even while the remainder of the indicator remains fixed in position, the indicators being positioned on said base plate proximate a substantial portion of an arc described by the head of the golf club at points before, during and after the club contacts the ball, so that the user can tell what part of his swing needs improvement.
Claim 6
Dependent Claim
130 words
A golf training device adapted to support a golf ball comprising a base plate made of a material that can be subjected to magnetic forces; indicators which are held to the base plate by these magnetic forces, each of said indicators having a vibratory element which can be set into vibratory motion of sufficient amplitude and duration to signal the user visually that his club has come into contact with the indicator even while the remainder of the indicator remains fixed in position, the indicators being positioned on said base plate proximate a substantial portion of an arc described by the head of the golf club at points before, during and after the club contacts the ball, so that the user can tell what part of his swing needs improvement.
Claim 7
Dependent Claim
76 words
A golf training device comprising a structure of ferromagnetic material and a plurality of indicators held on the structure by magnetic forces, the indicators outlining the correct path of the golf club before, during and after ball contact, each indicator being held at any one of a wide variety of positions which are determinable by the user, each indicator being capable of signalling it has been struck while part of the indicator remains fixed in position.
Claim 8
Dependent Claim
76 words
A golf training device comprising a structure of ferromagnetic material and a plurality of indicators held on the structure by magnetic forces, the indicators outlining the correct path of the golf club before, during and after ball contact, each indicator being held at any one of a wide variety of positions which are determinable by the user, each indicator being capable of signalling it has been struck while part of the indicator remains fixed in position.
