Marlo ABSTRACT: A practice device for golfers for teaching the basic principles of driving, the device comprising a flexible rope or chord for defining an arc of travel for a golf club head, a cross rod for defining the position of the players feet, a forward extending rod extending from the cross rod a plastic cup upon which a golf ball is supported, and a straight bar extending from the plastic cup into the direction toward the green.

Another object is to provide a diamond golf meter which is comprised of a plurality of linear members which may be formed either from rope, flexible chords and the like, and which are adjustably enjoined by means of a plastic cup and a base gusset.

Yet another object of the present invention is to provide a diamond golf meter for learning the basic principles of golf and which may be conveniently used indoors within a house or office or out of doors in a backyard or the like.

Other objects of the present invention are to provide a diamond golf meter which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation.

These and other objects will be readily evident upon a study of the following specification and the accompanying drawing wherein:

FIG. I is a perspective view of the present invention shown in operative use,

FIG. 2 is an enlarged cross-sectional view taken along the line 2-2 of FIG. 1, and

FIG. 3 is a bottom perspective view thereof and FIG. 4 is an enlarged plan view of a base gusset for securing certain components together.

Referring now to the drawing in detail, the reference numeral represents a diamond golf meter, according to the present invention, wherein there is a bow 11 of generally arcuate configuration and which may be formed either from rope or flexible chord, as preferred. A forward extending rod 12 bisects the bow 11, the rod comprising a straight member that may be likewise made from similar material as the bow or of any other inexpensive material such as plastic rod or the like. One end of the rod 12 is connected to a base gusset 13, the base gusset being centrally located along a transverse extending cross rod 14 which defines the position for aligning of the feet 15 of the golf player 16.

A plastic cup 17 is mounted at the junction of the bow 11 and the rod 12, the plastic cup comprising a circular disc 18 having two pairs of bottom tacks on the underside thereof so as to raise the disc 18 above the level of a floor or ground 19 and thus allow the bow and rod to pass there beneath. Altemately, the bottom tacks may be made to comprise downward extending eyelets 20 through which the bow and rod may be threaded, as shown in FIG. 3 of the drawing. Either form of construction is covered by the present invention. The plastic cup further includes an upwardly extending central tee upon the upper end of which a golf ball 21 may be seated. The tee 22 includes a downwardly dished depression upon the upper end thereof.

A bar 23 comprises a straight member made likewise from string, cord or other equivalent material, one end of the bar being positioned beneath the plastic cup, and the opposite end of the bar having an arrowhead 24 secured thereto, the arrowhead being made from cardboard or inexpensive plastic.

In operative use, the golf player positions himself, as shown in FIG. 1 of the drawing, with his toes of the feet 15 being placed adjacent the cross rod 14 and the rod 12 extending forwardly centrally therefrom. The bow 11 is adjusted along the length of the rod 12 so as to be suited to the particular size of the player. The bow 11 defines the arc along which the golf club 25 is made to swing. The bar 23 is made to point toward the green.

The present device may be used with either wood or ion golf clubs. For out of door use, a plastic ball or a regular golf ball may be used. For indoor use, a soft ball or a simulated ball may be used.

Thus there has been provided a diamond golf meter which can be used by golf players in practice work and learning the basic principles of golf.

I claim:

1. In a diamond golf meter, the combination of a plurality of linear members, said members being positioned together to form a pattern, said pattern defining the position for placement of a golfers feet and defining the proper golf club swing, said members comprising an arcuate bow, said bow being bisected by forwardly extending rod, the junction of said bow and rod having a golf ball supporting plastic cup positioned thereupon, a first end of a straight bar being located beneath said plastic cup, the opposite end of said bar being directed to point toward a golf course green, said bar extending tangentially respective to said bow, at base gusset, one end of said forwardly extending rod being rigidly affixed to said base gusset, and a cross rod being centrally secured to said gusset at right angle to said forwardly extending rod, said cross rod defining the position for said golfers feet, said plastic cup comprising a circular disc mounted in elevated position upon a plurality of downwardly extending legs, said disc having an integral upwardly extending tee at the center thereof, the upper end of said tee having a downwardly dish depression for supporting a golf ball thereupon the opposite end of said tangential bar being provided with an arrowhead, said arrowhead being directed to point toward said green, said base gusset comprising a diamond-shaped member upon the upper side of which an advertising name may be imprinted, said how being adjustable in position along said forward extending rod, and the arc of said bow being adjustable to accommodate difierent swing arcs of difi'erent-sized players and golf clubs.
