Claims
I claim
1. A portable device for aiding a golfer in driving a golf ball
along a straight path comprising; a pliant shape-holding mat; said
mat shaped in a generally isosceles triangular configuration with
the base having a length of about three to six times the height and
a height of from about 4 to about 8 inches; indicia denoting the
height of said mat; and a golf tee receiving opening through said
mat about midway of the length of the denoting indicia and about
one inch normally offset therefrom.
2. The invention defined in claim 1 wherein the length of the base
of the generally triangular mat is about 24 inches and the height
of the triangular mat is about 5 inches.
3. The invention defined in claim 2 wherein the mat is formed of
natural or synthetic rubber.
Description
This invention relates to a device for aiding a golfer in driving a
golf ball along a straight predetermined path.
Golf swing indicating devices, feet and ball positioning devices
for golfers, and other structures relating to golf instruction
improvement means are known in the art. However, most of such prior
art devices are complicated in nature, relatively expensive to
manufacture, difficult to use, and carry and assemble.
It is a primary object of the present invention to provide an
extremely simple, relatively inexpensive, highly portable structure
which is simple to use and when used will materially improve
straight driving of golf balls and will endow a golfer with a
proper and natural stance in addressing the golf ball.
A further object is to provide such a device that may be simply
folded and carried in a golfer's coat pocket, golf bag, or the
like, and moved and placed at will.
These and other objects and advantages will become apparent to
those skilled in the art from the following detailed description of
the invention which may be generally defined as a device for aiding
a golfer in driving a golf ball along a straight path comprising; a
pliant, shape-holding mat; the mat being shaped in a generally
isosceles triangular configuration with the base thereof having a
length of about three to six times its height, and its height of
from about 4 to about 8 inches; indicia denoting the height of said
mat, and an opening through the mat about midway of the length of
the denoting indicia and about 1 inch normally offset
therefrom.
The above and other features and objects and the manner of using
the invention will be best understood by reference to the following
description of a preferred embodiment of the invention taken in
conjunction with the accompanying drawings wherein:
FIG. 1 is a top plan view of an embodiment of the golf swing aiding
device illustrating the position of a golf ball, its direction of
flight, the position of the golf club head at impact with the ball
and the position of the feet of the golfer;
FIG. 2 is a perspective view of the device illustrated in FIG.
1;
FIG. 3 is a section substantially on line 3--3 of FIG. 1;
FIG. 4 shows the device being folded for carrying or storage.
Referring to the drawings, the improved golf swing aiding device is
generally designated 10. The device 10 comprises a pliant,
shape-holding mat with the mat shaped in a generally isosceles
triangular configuration with the base 12 having a length which is
about three to six times the height H of the triangle and the
height H is from about 4 to about 8 inches. In a preferred
embodiment, the length of the base 12 is 24 inches and the height H
of the triangle is 5 inches. The mat is constructed of material
firm enough to hold its shape but pliant enough to absorb the force
of a swinging golf club and still retain its form. Materials such
as rubber impregnated fabric, Rubberoid, natural or synthetic
rubber, plastic sheet material such as polypropolene or Mylar are
acceptable. Where a rubber-like material is employed a thickness
for a mat of about one-eighth inch has been found to be
satisfactory. Where 1/8 inch stock material is used, corrugating
the under surface of the mat, as shown at 14 in FIG. 4, is useful
as it renders the structure more pliable without material loss in
its shape-holding ability.
The height of the isosceles triangular structure is denoted by some
form of indicia generally designated 16. In the illustrated form of
the invention the indicia comprises a V-cut, as more clearly shown
in FIGS. 2 and 3, part way through the thickness of the material.
Since the triangular configuration is isosceles, the height H of
the triangle and the indicia 16 is perpendicular to the base 12 of
the structure. Further, as illustrated in the drawings, one end
generally designated 18 of the device is truncated as an aid in
establishing the forward end 20 of the golf swing aiding
device.
An opening 22, for example, about one-half inch in diameter, is
made in the mat and the position of the opening 22 is approximately
one to 11/2 inches toward end 20 from the indicia denoting line 16
and about half the height H. The opening 22 permits the player or
golfer to insert a golf tee 24 in the ground in the proper position
through the mat 10.
Referring particularly to FIG. 1, the use of the golf swing
improving device is illustrated. The device 10 is placed upon the
ground at the tee-off area with the base line 12 pointing towards
the flagstick or down the fairway in the direction the golfer
wishes the golf ball, generally designated 26, to travel. A golf
tee 24 is then placed in the ground through the opening 22 and the
left and right feet of the golfer are positioned equidistant on
opposite sides of the height line 16 of the device projected a
distance from the base line 12 suitable for the particular golfer.
The face 30 of the head 32 of a golf club is then squared using the
indicia denoting line 16 as a reference. With the indicia denoting
line 16 immediately back of the teed golf ball guesswork is
eliminated from the aligning of the face of the club in the proper
position for the struck golf ball to travel in a line of flight B
parallel to the base line 12 of the device. After having driven the
golf ball, the mat 10 is picked up, folded, and placed in the
player's pocket, golf bag, golf cart and the like, until the next
tee position.
From the foregoing description it will be seen that use of the
improved golf swing improving device will endow a player with a
proper and natural stance in addressing the golf ball and result in
improved, straight driving and lower scores.
