Abstract

Abstract A golf practice device is disclosed which incorporates a wedgeshaped member having an inclined upper surface from which a golf ball may be driven. The wedge-shaped member may be stationary or may be rotatable relative to a remote target, either rotatable manually or by means of a suitable drive means, thereby providing a variety of lies of the ball, including uphill, downhill, sidehill and crosshill. In an alternate embodiment of the invention the device comprises a pair of vertically-superimposed wedge-shaped members, each of which may be rotated relative to the other and a remote target, whereby the top surface of the upper wedge may assume a variety of angles ranging from the horizontal to a maximum inclination, as determined by the maximum angle of the individual wedges. In a preferred embodiment, an electric motor is provided for effecting rotation of the wedgeshaped member, and control means are provided to energize the motor and to stop the motor when the wedge-shaped member has reached a desired rotational position. The control means may include a control box having a plurality of push-buttons to select a desired rotational position of the wedge-shaped member, a plurality of micro-switches associated with an underlying base upon which the wedge-shaped member is disposed controlling the operation of the motor, each of the micro-switches corresponding to a single rotational position of the wedge-shaped member. A plurality of cam members may be disposed about the periphery of the wedge-shaped member, each of the cam members contacting one of the micro-switches to thereby stop rotation of the wedgeshaped member when a pre-selected one of the cam members contacts its corresponding micro-switch.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 189 words
A golf practice device comprising an underlying base, a wedge-shaped in vertical cross-section platform member supported on said base in superimposed relation and having a generally planar upper surface adapted to support a golfer and a golf ball thereupon and defining means from which a golf ball is driven, said upper surface being inclined at a pre-determined angle with respect to the underlying base, means extending between said platform member and underlying base for permitting rotation of said platform member relative to the underlying base about a substantially vertical axis while maintaining said platform member and underlying base in said superimposed relation to thereby change the direction and effective angle of inclination of said inclined upper surface relative to a fixed remote target and provide a plurality of lies for the golf ball supported thereupon to be driven therefrom, said inclined upper surface being covered with a crown of synthetic turf means simulating ground conditions of a golf course and which defines means for maintaining the lie position of a golf ball disposed thereon against the tendency of the golf ball to roll off of said inclined upper surface.
Claim 2
Dependent Claim 189 words
A golf practice device comprising an underlying base, a wedge-shaped in vertical cross-section platform member supported on said base in superimposed relation and having a generally planar upper surface adapted to support a golfer and a golf ball thereupon and defining means from which a golf ball is driven, said upper surface being inclined at a pre-determined angle with respect to the underlying base, means extending between said platform member and underlying base for permitting rotation of said platform member relative to the underlying base about a substantially vertical axis while maintaining said platform member and underlying base in said superimposed relation to thereby change the direction and effective angle of inclination of said inclined upper surface relative to a fixed remote target and provide a plurality of lies for the golf ball supported thereupon to be driven therefrom, said inclined upper surface being covered with a crown of synthetic turf means simulating ground conditions of a golf course and which defines means for maintaining the lie position of a golf ball disposed thereon against the tendency of the golf ball to roll off of said inclined upper surface.
Claim 3
Dependent Claim 25 words
A golf practice device as defined in claim 1, further comprising means for automatically effecting rotation of said wedge-shaped member relative to said underlying base.
Claim 4
Dependent Claim 49 words
A golf practice device as defined in claim 2, wherein said means for effecting rotation comprises an electric motor drivingly connected to said wedge-shaped member, and further comprising control means to energize said motor and to stop said motor when said wedge-shaped member has reached a desired rotAtional position.
Claim 5
Dependent Claim 107 words
A golf practice device as defined in claim 3, wherein said control means includes a control box having a plurality of push buttons to select a desired rotational position of the wedge-shaped member, a plurality of micro-switches associated with said base member and controlling the operation of said motor, each of said micro-switches corresponding to a single rotational position of said wedge-shaped member, and a plurality of cam members disposed about the periphery of said wedge-shaped member, each of said cam members contacting one of said micro-switches to thereby stop rotation of said wedge-shaped member when a pre-selected one of said cam members contacts its corresponding micro-switch.
Claim 6
Dependent Claim 37 words
A golf practice device as defined in claim 1, wherein said base member comprises a mobile base having roller means supporting same, whereby said base member and said wedge-shaped member may be moved to any desired location.
Claim 7
Dependent Claim 71 words
A gold practice device as defined in claim 1, wherein said base member includes an inclined upper surface upon which said wedge-like member is supported, said base member and said wedge-like member being rotatable relative to each other, whereby rotation of said wedge-shaped member and said base member of said upper surface of relative to each other will alter the angle of inclination of said upper surface of said wedge-shaped member.
Claim 8
Dependent Claim 50 words
A golf practice device as defined in claim 6, wherein said base member and said wedge-like member are individually rotatable relative to the remote target, whereby the direction and angle of inclination of said inclined upper surface of said wedge-like member may be selectively varied relative to the remote target.
Claim 9
Dependent Claim 17 words
A golf practice device as defined in claim 7, wherein said base member comprises a wedge-shaped member.
