1 TRAINING DEVICE FOR GOLF BALL PUTTING BACKGROUND OF THE INVENTION This invention relates to training devices for golf ball putting and, more particularly, to a novel training device for golf ball putting having sound targets of different acoustic characteristics and adapted to produce different sounds when hit by a golf ball.

Several kinds of training devices for golf ball putting have been known. These devices are in the form of a plate or sheet formed with a hole or cup-like recess into which golf balls are driven. Therefore, the known training devices provide a mere target to which the golf ball is to be driven. With such devices a player must look after a putted ball after his putting action to find out whether or not the ball has entered the hole or the recess. This is disadvantageous because his putting form will be disturbed by looking after the ball and there will be needed some interval of time until he assumes a putting form again for the next putting action.

SUMMARY OF THE INVENTION It is an object of this invention to eliminate such disadvantages of the known training devices for golf ball putting.

It is another object of this invention to provide a new training device for golf ball putting wherein a player can judge the course of the ball without looking after the ball which he is putting.

It is still another object of this invention to provide a new training device wherein a player can judge the course of the ball by merely hearing a sound produced by one of a plurality of targets.

A further object of this invention is to provide a novel training device for golf ball putting wherein adjustment of the positions of a plurality of targets can be easily made.

A still further object of this invention is to provide a novel training device wherein adjoining targets are arranged so that they do not produce sounds at the same time even when the ball runs intermediate of the adjoining targets.

A further object of this invention is to provide a novel training device which may be easily assembled and disassembled.

According to major features of this invention, briefly summarized, there is provided a training device for golf ball putting which comprises, in combination, a support frame having a horizontal beam, a central sound target freely suspended from said beam, at least one first side sound target suspended from said beam at one side of said central target and having an acoustic characteristic different from that of said central target, and at least one second side sound target suspended from said beam at the other side of said central target and having an acoustic characteristic different from that of said central target.

The nature, principle, and utility of the invention will be more clearly apparent from the following detailed description with respect to preferred embodiments of the invention, also relative to secondary features, when read in conjunction with the accompanying drawings, in which like parts are designated by like reference numerals and characters.

BRIEF DESCRIPTION OF THE DRAWING In the drawing:

FIG. 1 is a perspective view of an exemplary embodiment of the training device for golf ball putting according to this invention;

FIG. 2 is a front elevation of the training device;

FIG. 3 is a transverse section, on an enlarged scale, taken along the line IIIIII of FIG. 2;

FIG. 4 is a front view of a modification of a central sound target; and

FIG. 5 is'a fragmentary front elevation similar to FIG. 2, showing a modification of the training device shown in FIG. 1.

DETAILED DESCRIPTION Referring first to FIGS. 1 and 2, there is shown a preferred embodiment of the training device for golf ball.

putting according to this invention. The training device is generally designated by reference numeral 2 and comprises a support frame 3 made preferably of a synthetic plastic and made up of a pair of upright pedestals 3a and a horizontal beam 312 connecting the pedestals 3a.

A central sound target 4 is suspended from the beam 3b at an intermediate part thereof. Similarly, a first side sound target 5 and a second side sound target 6 are suspended from the beam 3b at respective sides of the central target 4. The

sound targets

4, 5 and 6 are preferably in the form of a rectangular plate as shown. The central target 4 is made of a metal such as light alloy which will make a sound when a golf ball strikes against it. It is preferable that the central target has such an acoustic characteristic as to make a pleasant or gay sound when struck by the golf ball.

The first side target 5 is also made of a metal such as light alloy which however will make a sound different from that of the central target 4. For this purpose, the side target 5 may be formed with several slits 7 to produce a different sound effect. The second side target 6 is also made of a metal such as light alloy which will make a sound different from that of the central target 4 and preferably different from that of the first side target 5. For this purpose, the target 6 may be formed with a number of perforations 8.

In order to produce different sound effects, it will also be possible to use different kinds of materials for the three targets. For example, the

targets

4, 5 and 6 may be made of metal, plastic and wood, respectively.

These three targets are arranged in a horizontally equally spaced-apart and mutually adjoining relationship and are of substantially the same dimensions. As is clearly shown in FIG. 2, the bottom edges of the three

targets

4, 5 and 6 are at the same horizontal level and spaced apart from the ground by a distance A which is smaller than, preferably about eight tenth of, the diameter of a golf ball B. The distances between the adjoining vertical edges of the adjoining targets are smaller than the diameter of the golf ball B, and the lower two corners of the central target 4 are preferably cut out at 4a.

Each of the

targets

4, 5 and 6 is suspended from the beam 3b by means of suspension means 10. As is most clearly shown in FIG. 3, the suspension means 10 includes a bracket 11 preferably made of a synthetic resin and secured to the front surface of the beam 3 by adhesive, for example. The bracket 11 is of an L- shaped cross section and forms between the upright extension thereof and the front surface of the beam 3 an upwardly opening horizontal gap in which is removably fitted a downwardly extending tab 12a of a suspension fitting 12 of generally U-shaped cross section.

A front extension or a panel 12b of the fitting 12 extends downward along the front face of the bracket 11 beyond the lower edge thereof. A pair of flexible thin joint pieces 13 such as short strips of flexible synthetic plastic are secured at the upper ends thereof to the lower part of each of the fittings 12, and at the lower ends thereof to the upper edge of each of the

targets

4,5,6. The thin flexible joint pieces are advantageous in obtaining a good sound effect of the targets.

It will be understood that each of the targets is freely swingable back and forth. The front panel 12b of each fitting may be provided with a forwardly projecting front tab 12c which may be pinched by the fingers when mounting and removing the fitting 12 into and out of the gap formed behind the vertical extension of the bracket 11.

As is clearly shown in FIGS. 1 and 2, the horizontal length of the bracket 11 is greater than that of latter 12 so that the fitting may be shifted horizontally along the bracket 11 by manipulating the tab 120 thereof to adjust the horizontal spacing between the vertical edge of the associated target and the vertical edge of the adjoining target.

In use, the training device according to this invention is placed on a lawn, a carpet or a training mat, and a player stands at an appropriate distance from the front side of the device. Then, the player hits or putts a golf ball with a putting club toward the device. When the putted ball takes the best course toward the targets, it will hit the central target 4 so that it will make a specific sound whereby the course of the ball will be known without looking at the device.

It will readily be understood that when the putted ball deviates from the best course it will hit one of the

side targets

5 and 6 and the respective, different characteristic sound will be heard whereby the course of the ball will again be known without looking at the target. Further, when the putted ball runs intermediate of two adjoining targets, it will pass through the intermediate space between the targets without hitting either of them, because of the provision of the cutout 4a. Accordingly, in such a case it can be avoided that two kinds of sounds are produced at the same time, which would be confusing in judging the course of the ball without looking after the putted ball. Thus, it will be noted that the player can putt the balls continually or successively while making delicate adjustment to the manner of putting because he can judge the courses of the putted balls merely by hearing the sounds of the targets without looking after the balls.

FIG. 4 shows a modified central target 4 having a bell 14 suspended by a string 15 in an opening 16 formed in the target 4. It will be noted that the bell 14 rings when the central target 4 is hit by a golf ball.

In FIG. 5 there is shown a modified training device in which the side targets 5 and 6 are also formed with

corner cutouts

5a and 6a, respectively. In this modification the spacing between adjoining vertical edges of the adjoining targets may be made smaller.

It is advantageous to prepare a further or alternative central target 4A as shown by a dot and dash line in Flg. 2. This alternative central target is of a narrower horizontal width and may be used in place of the central target 4 when a player has improved his putting technique by utilizing the training device fitted with the broader central target 4.

In the examples shown in the drawings, only on side target is provided at each side of the central target. But it is also possible to provide more than one side target at each side of the central target. In this case a wider range of the ball courses will be covered by the targets.

Furthermore, the suspension means for the targets may be wire strings which serve to hang the targets from the horizontal beam.
