Abstract A golf practice aid providing a club head which simulates an actual putter head but having an opening, which with a proper stroke, may be swung over a golf ball without striking the same. An adapter is provided for orienting the club head with respect to a golf club shaft to achieve various shaft to club face positions.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
A golf practice device, comprising: an integrally formed unitary structure, said structure including; a channel of uniform cross-section having first and second parallel walls, the beginning of each wall being defined by a parallel linear edge; first and second putter feet, each integrally formed with a respective one of said first and second parallel walls; and said channel forming an opening sized for passing over a golf ball resting on the ground when a proper putting swing is made, said putter feet being shaped and positioned such that said device simulates the placement of an actual putter on the playing surface.
Claim 2
Dependent Claim
101 words
A golf practice device, comprising: an integrally formed unitary structure, said structure including; a channel of uniform cross-section having first and second parallel walls, the beginning of each wall being defined by a parallel linear edge; first and second putter feet, each integrally formed with a respective one of said first and second parallel walls; and said channel forming an opening sized for passing over a golf ball resting on the ground when a proper putting swing is made, said putter feet being shaped and positioned such that said device simulates the placement of an actual putter on the playing surface.
Claim 3
Dependent Claim
162 words
A golf practice device for practicing putting, comprising: an integrally formed structure, said structure including; a channel of uniform cross-section having first and second parallel walls, the beginning of each wall being defined by a parallel linear edge; front arch means forming a semicircular arch centrally disposed above said channel, the front contour of said semicircular arch terminating at first and second end points, each end point being coterminous with the beginning of a respective one of said parallel linear edges; rear arch means formed integrally with said front arch means for defining a rear arch above said channel; first and second putter feet, each integrally formed with a respective one of said first and second parallel walls; and said channel and front and rear arch means forming an opening for passing over a golf ball when a proper swing is made, said putter feet being positioned such that said device simulates the placement of an actual putter on the playing surface.
Claim 4
Dependent Claim
162 words
A golf practice device for practicing putting, comprising: an integrally formed structure, said structure including; a channel of uniform cross-section having first and second parallel walls, the beginning of each wall being defined by a parallel linear edge; front arch means forming a semicircular arch centrally disposed above said channel, the front contour of said semicircular arch terminating at first and second end points, each end point being coterminous with the beginning of a respective one of said parallel linear edges; rear arch means formed integrally with said front arch means for defining a rear arch above said channel; first and second putter feet, each integrally formed with a respective one of said first and second parallel walls; and said channel and front and rear arch means forming an opening for passing over a golf ball when a proper swing is made, said putter feet being positioned such that said device simulates the placement of an actual putter on the playing surface.
Claim 5
Dependent Claim
127 words
A golf practice device for practicing putting, comprising: an integrally formed one-piece structure including; a semicircular arch, each end of said arch extending to form a pair of parallel linear edges; a spherical section formed integrally with said arch and extending behind said arch, said section being dimpled to resemble a golf ball; a channel of uniform cross-section having first and second parallel walls, the beginning of each wall being defined by a respective one of said parallel linear edges, said channel extending beneath said spherical section; first and second putter feet, each integrally formed with a respective one of said first and second parallel walls; and said channel and semicircular arch being shaped to pass over a golf ball when a proper putting swing is made.
Claim 6
Dependent Claim
127 words
A golf practice device for practicing putting, comprising: an integrally formed one-piece structure including; a semicircular arch, each end of said arch extending to form a pair of parallel linear edges; a spherical section formed integrally with said arch and extending behind said arch, said section being dimpled to resemble a golf ball; a channel of uniform cross-section having first and second parallel walls, the beginning of each wall being defined by a respective one of said parallel linear edges, said channel extending beneath said spherical section; first and second putter feet, each integrally formed with a respective one of said first and second parallel walls; and said channel and semicircular arch being shaped to pass over a golf ball when a proper putting swing is made.
Claim 7
Dependent Claim
31 words
The device of claim 3 further including a rear arch having a semicircular top portion into which said spherical section is integrally formed and which is integrally formed with said channel.
Claim 8
Dependent Claim
20 words
The device of claim 4 wherein said rear arch extends to form a pair of parallel spaced-apart, rearwardly-extending guide fins.
Claim 9
Dependent Claim
36 words
The device of claim 5 wherein said channel is of a width wider than the diameter of a standard golf ball, said width being selected to pass said ball when a proper putting swing is made.
Claim 10
Dependent Claim
32 words
The device of claim 5 wherein said channel is substantially 1/4-inch wider than the diameter of a golf ball and said front semicircular arch extends substantially 1/4-inch above a standard golf ball.
