Abstract
Abstract A device for use in connection with a golf game or practice apparatus for simulating a fairway surface to enable a player to execute each shot as he would in actual play, especially enabling the player to "strike down" at the golf ball with the simulated feel of taking a chunk of turf but without damaging the simulated fairway surface. The device utilizes an artificial grass turf secured to a cushioned support that is movable in the direction of flight of the ball and compressible when the surface is struck during the golfer's swing. The movable and compressible portion of the artificial turf will return to its original position as soon as the club head is disengaged from the turf. The movable section of artificial turf together with the cushioned support thus provides the golfer with the same "feel" as if actual turf had been taken during the golf shot.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
220 words
A device for simulating actual fairway turf so as to provide for proper execution of a golf shot when a golf ball resting on said device is struck by a golf club, said device comprising a supporting base, artificial turf means having front, rear and side margins supported by and slidably movable relative to said base in a generally horizontal plane, said turf means having a layer of resilient material extending between said front, rear and side margins so as to provide a cushioned layer, said turf means also having an artificial turf layer on top of said cushioned layer, guide members extending from the side margins of said artificial turf means transversely to the direction of movement thereof, the portions of the supporting base adjacent the side margins of said artificial turf means including grooves corresponding to said guide members and in which said guide members are engaged, said guide members and grooves providing guide means to limit movement of said turf means forwardly and rearwardly primarily in a horizontal plane from an initial at-rest position in the direction of flight of a golf ball when struck by a golf club, and resilient means combined with said turf means to return said turf means to said initial position when said turf means is moved forwardly during a golf shot.
Claim 2
Independent Claim
220 words
A device for simulating actual fairway turf so as to provide for proper execution of a golf shot when a golf ball resting on said device is struck by a golf club, said device comprising a supporting base, artificial turf means having front, rear and side margins supported by and slidably movable relative to said base in a generally horizontal plane, said turf means having a layer of resilient material extending between said front, rear and side margins so as to provide a cushioned layer, said turf means also having an artificial turf layer on top of said cushioned layer, guide members extending from the side margins of said artificial turf means transversely to the direction of movement thereof, the portions of the supporting base adjacent the side margins of said artificial turf means including grooves corresponding to said guide members and in which said guide members are engaged, said guide members and grooves providing guide means to limit movement of said turf means forwardly and rearwardly primarily in a horizontal plane from an initial at-rest position in the direction of flight of a golf ball when struck by a golf club, and resilient means combined with said turf means to return said turf means to said initial position when said turf means is moved forwardly during a golf shot.
Claim 3
Dependent Claim
42 words
The device of claim 1 in which said resilient means is an elongated resilient member having one end affixed to said artificial turf means at its rear margin and the other end affixed to said base rearwardly of said artificial turf means.
Claim 4
Independent Claim
187 words
A device for simulating actual fairway turf so as to provide for proper execution of a golf shot when a golf ball resting on said device is struck by a golf club, said device comprising a supporting base, artificial turf means having front, rear and side margins supported by and slidably movable relative to said base along a path generally in a horizontal plane, said artificial turf means and said base having corresponding tongue and groove portions slidably engagable with each other to guide said turf means and limit its movement relative to said base along said path from an initial at-rest position forwardly primarily in the direction of flight of a golf ball when struck by a golf club, said turf means having a layer of resilient material extending between said front, rear and side margins so as to provide a cushioned layer, said turf means also having an artificial turf layer on top of said cushioned layer, and resilient means combined with said turf means to return said turf means to said initial position when said turf means is moved forwardly during a golf shot.
Claim 5
Independent Claim
187 words
A device for simulating actual fairway turf so as to provide for proper execution of a golf shot when a golf ball resting on said device is struck by a golf club, said device comprising a supporting base, artificial turf means having front, rear and side margins supported by and slidably movable relative to said base along a path generally in a horizontal plane, said artificial turf means and said base having corresponding tongue and groove portions slidably engagable with each other to guide said turf means and limit its movement relative to said base along said path from an initial at-rest position forwardly primarily in the direction of flight of a golf ball when struck by a golf club, said turf means having a layer of resilient material extending between said front, rear and side margins so as to provide a cushioned layer, said turf means also having an artificial turf layer on top of said cushioned layer, and resilient means combined with said turf means to return said turf means to said initial position when said turf means is moved forwardly during a golf shot.
Claim 6
Dependent Claim
34 words
The device of claim 3 in which said artificial turf means includes means to reduce the friction between said turf means and said base when said turf means move slidably relative to said base.
