Abstract
Abstract Portable apparatus for training a golfer to putt a ball correctly. The apparatus has guide rails and extensible flexible cords which guide the golfer in swinging the putter along a straight line and hitting the ball along a desired path. The rails are secured to the ground by pins which project from the lower surfaces of the rails. When the device is not in use, the flexible cords are wrapped about the pins, and the rails are brought together with the pins of one rail being received in sockets in the other. The device can be broken down or collapsed into a relatively small package which is easily carried in a golf bag.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
169 words
Collapsible apparatus for training a golfer to putt a ball along a target line, comprising a pair of elongated guide rails having ground engaging pins projecting from first sides thereof and pin receiving sockets in said first sides, said guide rails being movable between a collapsed position in which the rails are juxtaposed with the first sides facing each other and the pins interfitting with the sockets of the opposite rails to hold the rails together and an operating position in which the guide rails are positioned in spaced parallel relation on opposite sides of the target line with the first sides facing in a downward direction and the pins extending into the ground to secure the rails in position, and an axially extensible guide member extending from one end of each of the guide rails for movement between a retracted position relative to the guide rails when the guide rails are in their collapsed position and an extended position when the guide rails are in the operating position.
Claim 2
Dependent Claim
169 words
Collapsible apparatus for training a golfer to putt a ball along a target line, comprising a pair of elongated guide rails having ground engaging pins projecting from first sides thereof and pin receiving sockets in said first sides, said guide rails being movable between a collapsed position in which the rails are juxtaposed with the first sides facing each other and the pins interfitting with the sockets of the opposite rails to hold the rails together and an operating position in which the guide rails are positioned in spaced parallel relation on opposite sides of the target line with the first sides facing in a downward direction and the pins extending into the ground to secure the rails in position, and an axially extensible guide member extending from one end of each of the guide rails for movement between a retracted position relative to the guide rails when the guide rails are in their collapsed position and an extended position when the guide rails are in the operating position.
Claim 3
Dependent Claim
43 words
The apparatus of claim 1 wherein the extensible guide member comprises an elongated flexible cord which is adapted to be wrapped about the pins in its retracted position and to extend along a line parallel to the target line in its extended position.
Claim 4
Dependent Claim
55 words
The apparatus of claim 2 wherein the cord is elastic, one end of the cord being connected to one end of the guide rail and the other end of the cord being adapted to be anchored to the ground to hold the cord in a stretched condition when the cord is in its extended position.
Claim 5
Dependent Claim
41 words
The apparatus of claim 1 including indexing marks on the side of one of the rails opposite the one side, said marks facing in an upward direction and being visible to the golfer when the rails are in the operating position.
Claim 6
Dependent Claim
35 words
The apparatus of claim 1 wherein the pins and sockets are provided in such manner that the ends of the rails are aligned directly with each other when the rails are in the collapsed position.
Claim 7
Dependent Claim
146 words
Apparatus for training a golfer to putt a ball along a target line, comprising a pair of elongated rails positioned in spaced parallel relation on opposite sides of the target line and being separated by a distance somewhat greater than the width of the head of a putting club, said rails having a height corresponding to the diameter of the ball so that the golfer must swing the head of the putting club along a straight line between the rails in order to strike the ball when it is positioned between the rails, ground engaging pins extending downwardly from the lower sides of the guide rails and anchoring the rails to the ground, and an elongated flexible cord extending axially from each of the guide rails and anchored to the ground on opposite sides of the target line to define a target path for the ball.
Claim 8
Dependent Claim
146 words
Apparatus for training a golfer to putt a ball along a target line, comprising a pair of elongated rails positioned in spaced parallel relation on opposite sides of the target line and being separated by a distance somewhat greater than the width of the head of a putting club, said rails having a height corresponding to the diameter of the ball so that the golfer must swing the head of the putting club along a straight line between the rails in order to strike the ball when it is positioned between the rails, ground engaging pins extending downwardly from the lower sides of the guide rails and anchoring the rails to the ground, and an elongated flexible cord extending axially from each of the guide rails and anchored to the ground on opposite sides of the target line to define a target path for the ball.
Claim 9
Dependent Claim
51 words
The apparatus of claim 6 including sockets formed on the lower sides of the guide rails for receiving the ground engaging pins of the opposite rails when the rails are removed from the ground and positioned together in a closed position with the lower sides of the rails facing each other.
Claim 10
Dependent Claim
28 words
The apparatus of claim 7 wherein the flexible cords are adapted to be wrapped about the pins between the rails when the rails are in the closed position.
Claim 11
Dependent Claim

The apparatus of claim 6 wherein the cord extending from each of the rails comprises an elastic cord which is adapted to be affixed to the ground in a stretched condition.
Claim 12
Dependent Claim
29 words
The apparatus of claim 6 wherein one of the guide rails has axially spaced indexing marks on the upper side thereof for gauging the length of the putting stroke.
