Abstract

Abstract A golf practice mat formed of many separate strands of bendable members each individually extending upwardly from a base in spaced relation to one another to simulate blades of grass and a turfy surface of imitation grass, the individual strands being adapted to assume and stay in a bent condition impressed therethrough by the movement of a golf club head for collectively indicating the direction of such movement relative to a centerline aimed toward target until reset into upright condition preparatory to the next practice stroke of movement of a golf club head therethrough.

Claims Analysis

Total Claims: 19
Claim 1
Independent Claim 254 words
In a golf practice mat over which a golf club may be swung toward a golf ball to impress a pattern in the mat dependent upon the direction and depth of movement of the club head relative to said mat comprising: 1. a rigid base; 2. a plurality of independent strands of soft durable bendable wire able to withstand fatigue from repeated bending and straightening thereof; 3. means for mounting each of said strands of bendable wire in close spaced relation on said base with their free ends extending upwardly therefrom to a level providing a turfy grass like surface for supporting a golf ball thereon and for receiving an impression upon bending of such strands of bendable wire as are struck by the stroke of the head of a golf club over such surface; 4. a panel of rigid material substantially matching said base; 5. a plurality of apertures formed through said panel in identical spaced relation to the individual strands of bendable wire on said base for passage of each separate strand through an individual aperture in said panel; 6. upstanding rods on said base and extending through said panel for guiding the latter for vertical movement in parallel relation relative to said base from the lower toward the upper extremities of said strands of bendable wire extending upwardly therefrom; and 7. means on said panel for manually raising and lowering the latter relative to said base for simultaneously straightening each bent strand of bendable wire individually back into upstanding unbent condition.
Claim 2
Dependent Claim 254 words
In a golf practice mat over which a golf club may be swung toward a golf ball to impress a pattern in the mat dependent upon the direction and depth of movement of the club head relative to said mat comprising: 1. a rigid base; 2. a plurality of independent strands of soft durable bendable wire able to withstand fatigue from repeated bending and straightening thereof; 3. means for mounting each of said strands of bendable wire in close spaced relation on said base with their free ends extending upwardly therefrom to a level providing a turfy grass like surface for supporting a golf ball thereon and for receiving an impression upon bending of such strands of bendable wire as are struck by the stroke of the head of a golf club over such surface; 4. a panel of rigid material substantially matching said base; 5. a plurality of apertures formed through said panel in identical spaced relation to the individual strands of bendable wire on said base for passage of each separate strand through an individual aperture in said panel; 6. upstanding rods on said base and extending through said panel for guiding the latter for vertical movement in parallel relation relative to said base from the lower toward the upper extremities of said strands of bendable wire extending upwardly therefrom; and 7. means on said panel for manually raising and lowering the latter relative to said base for simultaneously straightening each bent strand of bendable wire individually back into upstanding unbent condition.
Claim 3
Dependent Claim 41 words
In a golf practice mat over which a golf club may be swung toward a golf ball to impress a pattern in the mat dependent upon the direction and depth of movement of the club head relative to said mat comprising:
Claim 4
Dependent Claim 41 words
In a golf practice mat over which a golf club may be swung toward a golf ball to impress a pattern in the mat dependent upon the direction and depth of movement of the club head relative to said mat comprising:
Claim 5
Dependent Claim 3 words
a rigid base;
Claim 6
Dependent Claim 3 words
a rigid base;
Claim 7
Dependent Claim 20 words
a plurality of independent strands of soft durable bendable wire able to withstand fatigue from repeated bending and straightening thereof;
Claim 8
Dependent Claim 20 words
a plurality of independent strands of soft durable bendable wire able to withstand fatigue from repeated bending and straightening thereof;
Claim 9
Dependent Claim 21 words
The mat in accordance with that of claim 1, in which said strands of wire are coated with a protective material.
Claim 10
Dependent Claim 24 words
The mat in accordance with that of claim 2, in which said strands of wire are coated with a material colored to simulate grass.
Claim 11
Dependent Claim 68 words
means for mounting each of said strands of bendable wire in close spaced relation on said base with their free ends extending upwardly therefrom to a level providing a turfy grass like surface for supporting a golf ball thereon and for receiving an impression upon bending of such strands of bendable wire as are struck by the stroke of the head of a golf club over such surface;
Claim 12
Dependent Claim 68 words
means for mounting each of said strands of bendable wire in close spaced relation on said base with their free ends extending upwardly therefrom to a level providing a turfy grass like surface for supporting a golf ball thereon and for receiving an impression upon bending of such strands of bendable wire as are struck by the stroke of the head of a golf club over such surface;
Claim 13
Dependent Claim 9 words
a panel of rigid material substantially matching said base;
Claim 14
Dependent Claim 9 words
a panel of rigid material substantially matching said base;
Claim 15
Dependent Claim 39 words
The mat in accordance with claim 1, including means for limiting upward movement of said panel comprising an enlarged head on each of said upstanding rods at the level of the upper extremities of said strands of bendable wire.
Claim 16
Dependent Claim 41 words
upstanding rods on said base and extending through said panel for guiding the latter for vertical movement in parallel relation relative to said base from the lower toward the upper extremities of said strands of bendable wire extending upwardly therefrom; and
Claim 17
Dependent Claim 41 words
upstanding rods on said base and extending through said panel for guiding the latter for vertical movement in parallel relation relative to said base from the lower toward the upper extremities of said strands of bendable wire extending upwardly therefrom; and
Claim 18
Dependent Claim 30 words
means on said panel for manually raising and lowering the latter relative to said base for simultaneously straightening each bent strand of bendable wire individually back into upstanding unbent condition.
Claim 19
Dependent Claim 30 words
means on said panel for manually raising and lowering the latter relative to said base for simultaneously straightening each bent strand of bendable wire individually back into upstanding unbent condition.
