GOLFER'S PRACTICE AID
Abstract
A golfer's training aid including a base, a vertical post and an
elongated horizontal member extending outward from the post. The
horizontal member includes a collar at one end and a golf ball
sighting member at the other end. A bend is provided in the
horizontal member adjacent the collar, whereby the collar
frictionally engages the post to maintain the sighting member in a
plane at a right angle to the post. The sighting member may be in
the form of a loop of wire or a solid disc. The sighting member is
positioned over a golf ball during the execution of a golf club
swing.

Claims
What is claimed is:
1. A golf practice aid comprising:
A. an upright post secured at one end thereof to a base; and
B. a horizontal sight piece having a collar at one end and a
circular golf ball sighting member at the other end thereof, said
collar being directly disposed over and contacting said post so as
to be releasably located thereon and slideable along said post,
a bend provided intermediate said sighting member and said collar
so that interior portions of said collar frictionally engage said
post, thereby causing said sighting member to lie in a plane at
substantially a right angle to said post, and the height of said
post being such that said sighting member may be moved to a
position above a golf ball during the execution of a golf club
swing for sighting on said golf ball.
2. A golf practice aid as in claim 1 wherein said sight piece and
post are constructed of stiff wire coated with plastic.
3. A golf practice aid as described in claim 1 wherein said
sighting member is a solid disk.
Description
SUMMARY OF THE INVENTION
This invention relates to a golfer's practice aid to assist a
golfer in practicing proper tee and fair-way strokes using the
appropriate club and a golf ball or practice ball.
One of the most common faults of the average golfer is in moving
the head during the golf swing. Use of the invention enables the
golfer to maintain a steady head position during the swing thus
reducing body sway and assisting the development of proper rhythm
of movement in the back and forward swing.
IN THE DRAWING
FIG. 1 is an elevational view of a golfer's practicing aid
embodying the principles of the present invention;
FIGS. 2 and 3 are plan and side views, respectively, on an enlarged
scale, of the sight piece of FIG. 1; and
FIGS. 4 and 5 are plan and side views, respectively, of a modified
sight piece.
The assembled device includes a base 10, a post 12 and a sight
piece 14. The base 10 may be made from plastic, hollowed out with
baseweights inserted. The base may be, for example, 5 inches long
by 23/4 inches wide by 11/4 high. The post 12, which is secured at
its lower end to the base 10, may be a length of 8 or 10 gauge wire
8 to 10 inches long and coated with plastic.
The sight piece may be made of a length of 10 gauge wire 10 to 12
inches long and carrying a punched-out disk 16 or collar at one end
and a wire loop 18 at its other end. The loop may have an inside
diameter of 11/2 to 2 inches, and the disk may be five-eighths
inches in diameter with a 1/4 inch hole in its center. The entire
sight piece 16 is coated with plastic to a thickness which will
give the disk 16 a locking action on the post 12 when the disk 16
is titled.
The locking action between the disk 16 and the post 12 is aided by
bending the wire three-fourths to 1 inches from the disk 16 so that
in the tilted position of the disk 16 the loop 18 will be parallel
to the ground. With this arrangement the sight piece 14 can revolve
about the post 12 if struck by the golf club.
In use the assembly is placed to one side of a golf ball 20, and
the golfer stands on the other side of the ball 20 and sights the
ball 20 in the loop 18.
The sight piece 14' of FIGS. 4 and 5 is the same as in FIGS. 1-3
except that the outer end is provided with a solid sighting disk 22
which is of smaller diameter than the ball 20.
It is not essential for the parts to be made separate, and the
device can be made in one or two pieces. However, separation of the
sight piece from the post allows the former to swivel if struck by
a golf club and thus avoids damage to the clubs.
