United States Patent() GOLF SWING INDICATOR Sidney H. Harp, Dearborn, Mich.

Application April 2, 1953, Serial No. 346,3134 1 Claim. Cl.v 2773-186);

This invention relates generally to training or instructive devices and pertains more particularly to a device for indicating the direction of swing of a golf club.

A primary object of this invention is to provide a training structure for enabling a golfer to perfect the execution of his swing.

Another object of this invention is to provide a training device for golfers which incorporates a centrally disposed target surrounded by properly positioned markers which, if struck, will indicate to the golfer the direction of his swing so that the desired execution may be practiced and perfected.

Another object of this invention is to provide a golf training device which includes a base provided with a series of triangularly disposed pegs pivotally secured thereto, the pegs being movable between normally upright positions to tipped over positions for indicating the direction of swing with respect to a centrally disposed target.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is a plan view of the training assembly;

Figure 2 is a vertical elevation of the assembly showing the same placed in operative position on the ground;

Figure 3 is an enlarged transverse section taken substantially along the plane of section line 3-3 of Figure 1 showing details of the golf ball supporting member;

Figure 4 is an enlarged sectional view taken along the plane of section line 4-4 of Figure 1 showing further details of the golf ball supporting assembly;

Figure 5 is a perspective of a training device incorporating a modied type of base;

Figure 6 is an enlarged perspective view of a portion of the base including the ball supporting assembly;

Figure 7 is a perspective view of one of the indicating Pegs;

Figure 8 is an enlarged perspective view of a modified form of ball supporting member; and

Figure 9 is a vertical section taken through the assembly shown in Figure 8.

Referring now more particularly to Figures 1 and 2, reference numeral 10 indicates generally the base of the assembly which is of generally triangular configuration having rounded apices and which is provided at each of these points with an integrally formed depending stake 12 for securing the assembly with respect to the ground as shown in Figure 2. Disposed substantially at a medial point of the base is a golf ball supporting assembly or target 14 which includes a bracket having a pair of spaced

side walls

16 and 18 interconnected by a top wall 20, the side walls being substantially triangular to define a ramp construction. The base ends of the triangular side walls are provided with notches which include the 2` slightly restricted neckz portions, 22 and, theA enlarged portions 24, see especially Figure 6.

The golf ball supporting assembly also includes the ball supportingjmember-26 proper of; generally T-shaped construction havingl aA lower cross. bar 28 having grooves 3l)v at its opposite, ends for reception in the enlarged portion 24 of the slots in the bracket. side walls.. A stern 32 extends; perpendicular from the cross arm and is provided at its upper free end withanenlargedicup 34 within which a golf b all may be received in supported.y relation. In assembling; theV grooved4 portions of theY cross arm are inserted into the notches. through. the restricted-neckzportions 22 thereof' whichA require a slight snapping` action tof allow the; cross arm to enter within the enlarged portions 24 of the notches. When the golf ball is received within the cup, the ball and the supporting member are prevented from being tipped over by virtue of the engagement of the stem 32 with the end wall 36 of the bracket this engagement providing a three-point support for the member 26 and consequently the golf ball.

Rigidly disposed at each corner of the base from the golf ball supporting assembly are the indicating

pegs

38, 4G and 42, each of which comprises a peg portion 44 forming with the lower cross arm 46 a substantially inverted T-shaped construction and the ends of the cross arms are grooved as at 48 in similar manner to member 26. The bracket assemblies, 50, 52 and 54 are provided adjacent the apices of the base and receive respective ones of the pegs, these brackets being formed and cooperating with the pegs in a similar manner to the previously described bracket assemblies. However, the inclined face of the rearward bracket 50 faces oppositely to the inclined faces of the remaining brackets on the base, for u purpose subsequently apparent.

When utilizing the device, the golfer takes a normal address to the ball and proceeds in executing his normal driving swing thereon. Since the back swing should follow along the ground behind the ball and consequently the supporting member 26, the rearward peg 38 should be tipped over from its normally vertical position during execution of the swing and, if the ball is properly driven in a straight ahead direction, neither of the

forward pegs

40 or 42 will be disturbed. lf the golfer is right handed,

, the tipping over of the far peg 4G indicates that the golfer is swinging his club in such a manner as to hook the ball and should the lower peg 42 in Figure 1 be tipped over, this indicates a slice.

The invention can, of course, also be used to allow a golfer to perfect an intentional hook or slice, such swings being necessary under certain circumstances.

Referring now more particularly to Figure 5, the golf ball supporting assembly 56 and the various marker peg assemblies 58 are identical in construction and operation to the previously described corresponding assemblies, the difference in the construction shown being that the base 16 is of arrow like configuration including the point 62 and tail 64. This construction is particularly desirable inasmuch as the specific configuration serves to enable the golfer to more easily position himself properly with respect to the base, the arrow-like configuration clearly pointing the direction of desired flight of the ball.

Referring now more particularly to Figures 8 and 9, a modified type of pivotal connection for the golf ball supporting member is shown which includes a socket base 66 receiving the ball 68 from which the stem 70 radially extends terminating at its upper end in the cup 72. This allows a more universal type of pivotal action of the golf supporting element with respect to the base 74.

From the foregoing, the construction and operation of the device will be readily understood and further explanation is believed to be unnecessary. However, since numerous modifications and changes will readily occur to lthose skilledin the art, it is not desired to limit the inven- A golf swing indicator comprising a triangular baseY having an indicating assembly disposed .at each of its apicesl and a ball supporting assembly disposed substantially medially thereof, each of said assemblies including a bracket portion in the form of a ramp. having spaced sides,'an end wall and extensions of said sides projecting beyond the end wall, each of said extensions having a notch therein provided with a'restricted neck, a Tshaped pin associated with each ofsaid assemblies and including anupright stem and a crossbar provided with grooved portions in its opposite ends pivotallyrreceived in the' l notchesr of said extensions such ,that the stem will abut the associated end wall and be held thereby in an upright position, the free end of the stem of said ball supporting assembly terminating in an enlarged cup adapted to receive a golfball, said indicating assemblies having their end walls facing outwardly away from said supporting assembly and positioned such that their longitudinal axes Y meet at a common point Within the confines of the same.
