FIELD OF INVENTION
[0001] The present invention relates to golf practice and exercise mats that enables a golfer
to practice golf swings using irons or woods and provides the golfer with exercise
to enhance strength by exerting resistance against the club head as the club travels
through the pile of the mat.
BACKGROUND OF INVENTION
[0002] Practice golf mats are known generally, for example U.S. Patent No. 3,459,107, which
discloses a golf striking mat that simulates hitting a golf ball from the "rough"
on a golf course, as does U.S. Patent No. 5,354,064. While these previous mats enable
a golfer to practice hitting out of the "rough", these constructions do not provide
enhanced resistance for exercise purposes, and do not provide a selection of contours
for use with different clubs.
[0003] Other mats provide varying heights of pile on the mats, such as disclosed in U.S.
Patent No. 3,414,266, which teaches a mat for practicing putting with three well defined
pile heights to simulate the roll of a golf ball on different green heights. U.S.
Patent No. 5,655,974 teaches a golf practice surface assembly having a plurality of
areas simulating, by height and density, golf course surfaces, e.g., fairway, rough
and sand trap. These prior mats provide a golfer some variety regarding the feel and
resistance of the grass when striking a ball resting on the mat with a golf club.
[0004] There are also some specialized practice mats such as U.S. Patent No. 4,294,450,
5,046,741, and 5,443,870. These constructions disclose mats for practicing putting
or for hitting a ball on an angled slope.
[0005] None of the prior art, however, discloses a contoured mat configuration for swinging
a golf club into an initial low height, through an upwardly inclined contour and exiting
through a following downwardly inclined contour.
OBJECT AND SUMMARY OF THE INVENTION
[0006] The object of the present invention is to provide a mat that gives golfers practice
and exercise by swinging a golf club through contoured pile that applies resistance
to the golf club as the club head travels though the pile, thus enhancing strength
and improving muscle memory.
[0007] A further object of the present invention is to provide the golfer, on one practice
mat, the realistic feel and resistance experienced when hitting a ball with an iron
or wood type club.
[0008] Basically, the mat of the present invention has at least one striking surface of
artificial grass pile, or similar material, increasing in height at an upwardly inclined
slope to an apex following which the grass pile height decreases in a gradual, approximately
linear downward slope. The contour allows the golfer to experience the increased resistance
as the club moves through progressively higher grass. This is accomplished by having
the golfer take a normal stance relative to the practice mat, the grass height increasing
along a path normally followed by a golf club when a golfer strikes a golf ball. When
the golfer performs a typical swing and follow through, the head of the golf club
initially sweeps over the initial low pile, then encounters an increasing height of
pile as the club travels through the upward slope of the pile to the apex at which
point the club head is completely enveloped within the grass pile, and gradually emerges
from the grass pile until the club head is completely free.
[0009] A preferred embodiment of the mat of the present invention is a single construction
having two striking areas with different contours of artificial grass piles, or similar
material. For purposes of discussion, the term "artificial grass" encompasses artificial
grass and other similar materials. One striking area, used with irons, has the pile
of artificial grass increasing in height at a moderate, curved upward slope to an
apex following which the grass strand height decreases in a gradual, approximately
linear, downward slope. The second striking area of the mat of the present invention
is for practicing with a wood type club. It has a grass pile contour in which the
grass pile height increases at a gradual, approximately linear upwardly inclined slope
to a transition point at which the grass pile height increases in a step change such
that the transition height exceeds the height of the previous grass pile by at least
two times, then decreases in a linear downward slope. When a golfer swings a wood
type club, the face of the club head encounters the step change in height thereby
causing the face of the club head to be enveloped in the grass pile and thus immediately
increasing the resistance felt by the golfer. As the golfer continues through the
swing to the follow through, the club head gradually emerges from the grass pile along
the downward slope, correspondingly reducing the resistance felt by the golfer.
[0010] A preferred embodiment of the present invention is the use of opposing contoured
piles to increase the resistance felt by the golfer. This embodiment includes a base
mat with a contoured striking area similar to those discussed above for the iron and
wood type golf clubs. Attached to the base mat and extending upwardly is a support
structure. The support structure is L-shaped with a vertical leg and a horizontal
leg. The horizontal leg is opposite the base mat and the vertical leg maintains the
horizontal leg and the base mat in a vertical spaced relationship. The horizontal
leg extends over a portion of the base mat. A projecting surface is attached to the
horizontal leg and is oriented toward the base mat. The projecting surface includes
a contoured pile that extends downwardly toward the contoured striking area of the
base mat. At a point intermediate the projecting surface and the base mat, portions
of the contoured striking area overlap a portion of the contoured pile of the projecting
surface such that the two portions mesh, thus increasing the resistance experienced
by a golfer as a club head engages the meshed portions.
[0011] Further details, features and advantages of the present invention will be understood
from the following disclosure of exemplary embodiments with reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0035] The golf practice mat 10 shown in Fig. 1 comprises an artificial grass mat having
sufficient area to include an iron striking area 20, a wood striking area 30 and a
golfer stance position 40, on which a golfer may position himself to practice his
golf swing using either striking area. The golf practice mat 10 has an artificial
grass carpet of varying grass pile height in the iron striking area 20 and the wood
striking area 30. The grass pile is affixed to a standard backing 45 which in turn
rests on a floor or ground when the golf practice mat 10 is in use. The golfer stance
position 40 illustrates the proper orientation of the golfer relative to the iron
striking area 20 and the wood striking area 30.
[0036] The iron striking area 20 is contoured as illustrated in Figs. 2-6. Shorter grass
pile extends for a first portion 24 of the iron striking area 20. A series of increasingly
taller grass piles extend along a second portion 22 of the iron striking area 20,
the relative increase conforming to a curved, moderately steep upward slope. A third
portion 26 of the iron striking area 20 begins at the apex of the second portion 22
and has a gradual, approximately linear slope of decreasing grass pile height. In
a preferred embodiment, the grass pile varies in height from about 2 inches to about
8 inches with the maximum height occurring at the apex of the second portion 22.
[0037] The wood striking area 30 is contoured as illustrated in Figs. 7-11. Grass pile extends
for a first portion 35 of the wood striking area 30 on an approximately linear gradual
upwardly inclined slope, approximately doubling in height. A second portion 33 of
the wood striking area 30, immediately following the first portion 35, has an initial
grass pile of a height that exceeds the height of the longer grass pile of the first
portion 35 by at least 2 times, preferably between about 3 to 5 times, thus creating
a vertical step-change transition 33a between the first portion 35 and the second
portion 33. After the vertical transition 33a, the grass pile of the second portion
33 of the wood striking area decrease on a gradual, approximately linear, downward
slope. In a preferred embodiment, the grass pile varies in height from about 2 inches
to about 8 inches, with the maximum height occurring at the vertical transition 33a.
[0038] The present invention is used in the following way. A golfer positions himself on
the golf practice mat 10 at the golfer stance position 40, with either an iron club
28 or a wood type club 38. Fig. 1 illustrates the positioning of the golfer relative
to the iron striking area 20 and the wood striking area 30. In Figs. 4 to 6, the golfer
is practicing with an iron 28. When the golfer swings the iron 28 in the direction
of the arrow, the head 29 of the iron 28 engages the second portion 22 of the iron
striking area 20 along face 29a of the head 29. As the golfer continues to swing the
iron 28, the head 29 of the club continues to travel through the increasingly taller
grass pile of the second portion 22, thereby increasing the resistance exerted against
the face 29a of the head 29 of the iron 28 with a correspondingly increasing resistance
felt by the golfer. When the club head is near the apex of the second portion 22,
the face of the club head is completely enveloped by the grass pile, as shown in Fig.
4. As the golfer continues the swing, shown in Fig. 5, the head of the iron starts
to exit the grass pile of the third portion 26 of the iron striking area 20. Finally,
as the golfer completes the swing, i.e. the follow through, the head 29 of the iron
28 completely disengages from the grass pile of the third portion 26 of the iron striking
area 20, as shown in Fig. 6.
[0039] In Figs. 9 to 11, the golfer is practicing with a wood type club 38. When the golfer
swings the wood type club 38 in the direction of the arrow, the head 39 of the wood
type club 38 engages the second portion 33 at the vertical transition 33a of the wood
striking area 30 along a face 39a of the head 39, as shown in Fig. 9. As the golfer
continues the swing, the face of the club head 39 becomes completely enveloped by
the grass pile of the second portion 33, applying an increased resistance against
the face 39a of the club head 39. As the golfer continues the swing, the club head
39 gradually emerges from the grass pile of the decreasing height second portion,
which exerts decreasing resistance against the face 39a of the head 39 of the wood
type club 38 with a correspondingly decreasing resistance felt by the golfer, shown
in Fig. 10. As the golfer completes the swing, the head 39 completely exits the grass
pile of the second portion 33 of the wood striking area 30, illustrated in Fig. 11.
[0040] An alternate preferred embodiment of the present invention combines the practice
golf mat 10 with a support structure 60 that positions a contoured pile extending
generally downwardly over a portion of the iron striking area 20 and the wood striking
area 30 such that the grass piles of the iron and wood striking areas 20, 30 intersect
and mesh with a portion of the opposing contoured pile held at a vertical spacing
relative to the practice golf mat 10, as shown in Figs. 12-23. As seen in Fig. 14,
the support structure 60 is L-shaped with a vertical leg 62 and a horizontal leg 64.
The golf practice mat 10 is attached to the vertical leg 62 opposite the horizontal
leg 64 such that the vertical leg 62 maintains . a vertical spacing between the golf
practice mat 10 and the horizontal leg 64 of the support structure 60. An upper carpet
75 is attached to the horizontal leg 64 of the support structure 60 and oriented toward
the iron striking are 20 and the wood striking area 30 of the golf practice mat 10,
as illustrated in Figs. 14 and 21. The upper carpet 75 is comprised of artificial
grass or similar material. The pile of the upper carpet 75 is of sufficient length
to intersect and mesh with the grass piles of the iron and wood striking areas 20,
30, as shown in Figures 15 and 18, thus significantly increasing the density of the
grass strands of the meshed area 79 at the intersection of the upper carpet 75 pile
and the piles of the golf practice mat 10, as illustrated in Fig. 22. The increased
density of grass strands results in an increase in the resistance felt by a golfer
when swinging a golf club through the meshed area 79.
[0041] The alternate embodiment of the present invention is used in the following way. A
golfer positions himself on the golf practice mat 10 at the golfer stance position
40, with either an iron club 28 or a wood type club 38. In Figs. 18-20, the golfer
is practicing with an iron 28. When the golfer swings the iron 28 in the direction
of the arrow, the head 29 of the iron 28 first engages an unmeshed area comprising
the second portion 22 of the iron striking area 20 and the pile of the upper carpet
75 along face 29a of the head 29. As the golfer continues the swing, the head 29 of
the club continues to travel through the increasingly taller grass pile of the second
portion 22, thereby increasing the resistance exerted against the face 29a of the
head 29 of the iron 28 with a correspondingly increasing resistance felt by the golfer.
When the club head 29 is near the apex of the second portion 22, the head of the club
engages the meshed area 79 comprising the second portion 22 and the pile of the upper
carpet 75, whereby the face 29a of the club head 29 is completely enveloped by the
meshed area 79, as shown in Fig. 18. As the golfer continues the swing, shown in Fig.
19, the head 29 of the iron 28 starts to exit the meshed area 79 along the third portion
26 of the iron striking area 20. Finally, as the golfer completes the swing, i.e.
the follow through, the head 29 of the iron 28 completely disengages from the grass
pile of the third portion 26 of the iron striking area 20, as shown in Fig. 20.
[0042] In Figs. 15 to 17, the golfer is practicing with a wood type club 38. When the golfer
swings the wood type club 38 in the direction of the arrow, the head 39 of the wood
type club 38 engages the meshed area 79 comprising the second portion 33 at the vertical
transition 33a of the wood striking area 30 and the upper carpet 75 along a face 39a
of the head 39, as shown in Fig. 15. As the golfer continues the swing, the face 39a
of the club head 39 becomes completely enveloped by the meshed area 79 of the grass
pile of the second portion 33, and the pile of the upper carpet 75, applying an increased
resistance against the face 39a of the club head 39. As the swing continues, the club
head 39 gradually emerges from the meshed area 79, shown in Fig. 16. As the golfer
completes the swing, the head 39 completely disengages from the grass pile of the
second portion 33 of the wood striking area 30, illustrated in Fig. 17.
