Abstract
Abstract A practice putting trainer for golfers is disclosed. The practice putting trainer of the present invention comprises an elongated, narrow, planar base having a width substantially equal to the diameter of a golf ball and sufficient stiffness to support a golf ball without perceptible deflection with a putting surface along its upper surface. A cup for receiving the golf ball is positioned at one end of the base. A ball rest for retaining the golf ball on the putting surface until struck by a putter is included on the bases. The ball rest is adjustably positioned along the length of the base to vary the length of the putt. A recess is provided in a forward edge of the ball rest to prevent transverse movement of the ball until struck by a putter.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
117 words
A practice putting trainer comprising: an elongated, narrow, planar base having sufficient stiffness to support a golf ball without perceptible deflection; a flat ball engaging putting surface formed along an upper portion of the base, said putting surface having a width substantially equal to the diameter of a golf ball; a cup for receiving the golf ball disposed at one end of the base; and a ball rest including a means for retaining the golf ball on the putting surface until struck by a putter; and wherein a golf ball rolling along the length of the base from the ball rest to the cup will roll off of the sides of the putting surface if hit improperly.
Claim 2
Dependent Claim
117 words
A practice putting trainer comprising: an elongated, narrow, planar base having sufficient stiffness to support a golf ball without perceptible deflection; a flat ball engaging putting surface formed along an upper portion of the base, said putting surface having a width substantially equal to the diameter of a golf ball; a cup for receiving the golf ball disposed at one end of the base; and a ball rest including a means for retaining the golf ball on the putting surface until struck by a putter; and wherein a golf ball rolling along the length of the base from the ball rest to the cup will roll off of the sides of the putting surface if hit improperly.
Claim 3
Dependent Claim
24 words
The practice putting trainer as defined in claim 1 further comprising: means for adjustably positioning the ball rest along the length of the base.
Claim 4
Dependent Claim
48 words
The practice putting trainer as defined in claim 2 wherein the means for adjustably positioning the ball rest along the base comprises the ball rest having a top wall abutting said putting surface and a pair of opposed, depending side walls slidingly engaging opposed sides of said base.
Claim 5
Dependent Claim
56 words
The practice putting trainer as defined in claim 3 wherein the means for retaining the golf ball on the putting surface comprises a recess formed along a forward end of said top wall of said ball rest with the edges of said recess preventing lateral movement of said ball when said ball is in abutment therewith.
Claim 6
Dependent Claim
75 words
The practice putting trainer as defined in claim 2 further comprising: the base of laminar construction; a thickened end including a notch complementary to the base abutting an end of the base, an upper surface of said thickened end flush with said putting surface, a recess formed in the thickened end forming a cup to receive a golf ball; and a flange attached to another end of the base, said flange retaining said ball rest.
Claim 7
Dependent Claim
52 words
The practice putting trainer as defined in claim 1 wherein an edge of the cup is slightly rounded to simulate a cup formed in a golf green and to allow entry of a properly struck ball and to cause a ball that is traveling too fast to enter and leave the cup.
Claim 8
Dependent Claim
38 words
The practice putting trainer as defined in claim 1 wherein: the one end of the base has an enlarged thickness so as to dispose the base at an upward inclined angle from the ball rest to the cup.
Claim 9
Dependent Claim
155 words
A practice putting trainer comprising: an elongated, narrow, planar base with a cup recessed to receive a golf ball at one end, a flat putting surface formed along an upper portion thereof, said base having sufficient stiffness to support a golf ball without perceptible deflection; an edge of said cup being slightly rounded to encourage the entry of a properly struck golf ball having the correct speed and to allow an improperly struck golf ball having too much speed to enter and leave the cup; and a ball rest including downward extending opposed side walls slidingly engaging said base and a top wall abutting said putting surface, a recess formed along a forward edge of said top wall to position the golf ball on said base while preventing transverse rolling of the golf ball, said ball rest being longitudinally movable along said base to selectively vary the distance from said ball rest to said cup.
Claim 10
Dependent Claim
155 words
A practice putting trainer comprising: an elongated, narrow, planar base with a cup recessed to receive a golf ball at one end, a flat putting surface formed along an upper portion thereof, said base having sufficient stiffness to support a golf ball without perceptible deflection; an edge of said cup being slightly rounded to encourage the entry of a properly struck golf ball having the correct speed and to allow an improperly struck golf ball having too much speed to enter and leave the cup; and a ball rest including downward extending opposed side walls slidingly engaging said base and a top wall abutting said putting surface, a recess formed along a forward edge of said top wall to position the golf ball on said base while preventing transverse rolling of the golf ball, said ball rest being longitudinally movable along said base to selectively vary the distance from said ball rest to said cup.
Claim 11
Dependent Claim
81 words
The practice putting trainer as defined in claim 8 wherein the base is formed from wood including a thick end providing sufficient material to form the cup therein, a flange overlaying the putting surface to retain said ball rest on the putting surface inclined upward toward said one end, a pair of opposed longitudinal recesses formed along sides of the base, and a pair of opposed inward directed projections associated with said ball rest and engageable with said opposed longitudinal recesses.
