Abstract

A forwardly inclined target board is rotationally mounted on each of five horizontally extending pivot shafts which are vertically spaced from each other: Each lower board extends upward to a position forward of the lower portion of the board immediately thereabove. An upright member positioned rearwardly of the target boards is mounted so as to be pivoted rearwardly about a pivot axis at its lower end in response to rearward movement of any of the target boards about its associated pivot shaft. The rearward movement of the upright member actuates a hydraulic system which provides the golfer at the tee area with an indication of the probable distance the ball would have been driven had it not hit one of the target boards. If a driven ball hits a narrow central zone of any target board with a force that would have enabled the ball to reach the cup in a putting green, suitable electrical components are provided to indicate that a hole-in-one has been scored. Additional boards and electrical components may be provided on opposite sides of the above mentioned five boards to indicate that a ball has been driven into a bunker or the rough. Golf balls are deflected downward from the target boards into a trough for being returned to the tee area.

Marlo Att0rneyWaters, Roditi, Schwartz & Nissen ABSTRACT A forwardly inclined target board is rotationally mounted on each of five horizontally extending pivot shafts which are vertically spaced from each other: Each lower board extends upward to a position forward of the lower portion of the board immediately thereabove. An upright member positioned rearwardly of the target boards is mounted so as to be pivoted rearwardly about a pivot axis at its lower end in response to rearward movement of any of the target boards about its associated pivot shaft. The rearward movement of the upright member actuates a hydraulic system which provides the golfer at the tee area with an indication of the probable distance the ball would have been driven had it not hit one of the target boards. If a driven ball hits a narrow central zone of any target board with a force that would have enabled the ball to reach the cup in a putting green, suitable electrical components are provided to indicate that a hole-in-one has been scored. Additional boards and electrical components may be provided on opposite sides of the above mentioned five boards to indicate that a ball has been driven into a bunker or the rough. Golf balls are deflected downward from the target boards into a trough for being returned to the tee area.

16 Claims, 3 Drawing Figures GAME TARGET This invention relates to apparatus for use in tests of skill, such as golf and archery. With the continued and increasing interest in the playing of golf and the pressures on the capacities of golf courses, there is a need for places off the course where golfers may practice driving during periods of both light and dark and of inclement weather. While practice areas are already known, where the golfer drives into a net, the golfer is given no indication of the length or accuracy of his drive, if the ball had not been brought to rest by the net. Where no net is used, and the golfer drives a succession of balls from a fixed tee into a field, a large area of land is required and problems of ball collection arise.

Apparatus for use in tests of skill comprises, according to this invention, a target towards which a ball or other projectile is to be directed and indicating means coupled to the target and arranged to give a single indication which increases with increasing force of impact of the projectile on the target and with increasing height ofimpact. The indication is thus at least approxi-. mately representative of the distance the projectile would have travelled if it had not met the target.

When applied to golf practice, the present invention provides a golf target which may be located close to the driving point; the indicating means then gives an indication representative of the length of drive, if the ball had not been impeded by the target. In this way, the area employed may be relatively small and the problem of ball retrieval mitigated. Indication of the accuracy of drive may also be given.

A second aspect of the invention resides in golf driving practice apparatus comprising a target including a plurality of independently mounted and upstanding target boards arranged at successively different levels, and indicating means coupled to all the boards and arranged to be operated by the impact of a ball on a board to a degree dependent on both the height of the board struck and the force of impact of the ball on that board.

Each of at least some of the target boards may carry means which when the board is struck on a limited zone with a prescribed impact operates an indicator representing a hole-in-one. Preferably, the target boards are flanked by auxiliary boards, which are arranged to give a separate indication when struck, and which represent that the ball has been driven wide. The separate indication may thus represent rough".

The invention will be more readily understood by way of example from the following description ofa golf driving target in accordance therewith, reference being made to the accompanying drawing, in which FIG. 1 is a front view of the target,

FIG. 2 is a section on the line IIII of FIG. 1, showing the target boards and the tee, and

FIG. 3 is a section on the line IIIIII of FIG. 1, show? ing the Rough and Bunker boards.

Referring first to FIG. 2, the target, which is shown at the left-hand side of that figure, is located a relatively short distance from the driving point indicated at 12.

This distance may be as short as feet, but is desirably about 45 feet. In the arrangement illustrated in FIG. 2,

the Tee level 13 is disposed above the ground level 14.

The target has a steel structure consisting of uprights 15, I6, 17, connected by cross members and permanently secured in the ground by feet 18. The uprights 15-17 carry five horizontal pivot shafts 20, which are spaced at regular intervals vertically and which extend the full width of the target. These shafts 20 pivotally support a number of target boards.

Centrally of the target, there are a number, shown as 5, of target boards21 mounted on the respective shafts 20 and therefore disposed at different vertical heights. Each target board 21 is pivotally mounted below center and is normally restrained in an inclined position by a stop 22 which is secured to the central upright 16. As will be seen, each target board 21 is inclined forwardly, with the upper edge nearer to the driving point than the lower. Further, each board 21, except the uppermost, overlaps the next higher board, whenviewed from the front, up to the height of the shaft 20 of that higher board.

Above the pivot shaft 20, each target board carries a rigid, rearwardly directed arm 23 which terminates in a cam-follower in the form of a roller 24. Each cam-follower 24 runs on an associated cam 25 secured rigidly to an upright member 26, which is shown as a steel section and which is pivotally mounted on trunnions 27 secured in the ground. Movement of the member 26 in a clockwise sense, as viewed in FIG. 2, is limited by a stop 28, while movement in the counter-clockwise direction is restrained by a spring 30 and limited by a second stop 31. The cams 25 are individually shaped to conform with the movement of the cam-follower on pivotal movement of the respective board 21.

When a ball driven from the tee l2 strikes one of the target boards 21, the member 26 is driven anticlockwise by an amount dependent on (a) the force of impact with which the ball strikes the board, and (b) the height of the board that is struck. Thus, for a ball of a given speed, and thus a given force of impact, the angular movement of the member 26 is greatest when the ball strikes the uppermost target 21 and least when it strikes the lowermost target. As the distance that the ball would have travelled, if it had not been impeded by the target is dependent both upon its speed and the height of its trajectory, the angular movement of the member 26 is an indication of that distance. The member 26 is coupled to indicating means which indicate at the driving position the distance represented by the movement of that member.

One such indicating means will now be described. In FIG. 2, the member 26 is shown as having secured to it a pressure member in the form of a foot 33 engaging on a cylinder 34 of flexible material, such as rubber. The cylinder 34 is supported in an arm 35 secured in the trunnions 27 and has an internal diaphragm (not shown) separating a volume of liquid within the cylinder from the cylinder outlet which is connected to a flexible pipe 36. Pipe 36 is connected through a nonreturn valve 37 to a pressure indicator 38 which is disposed at the driving position and which is calibrated in yards of drive. A second non-return valve 40 connects the pipe 36 with atmosphere and is disposed at the target position. A manually operated reset valve 41 disposed adjacent to the indicator 38 can be opened to release any pressure in the air line between valve 37 and indicator 38.

When the member 26 is driven anti-clockwise, the foot 33 acts on the flexible cylinder 34 to distort the internal diaphragm and force out of the cylinder an amount of air dependent on the angular movement. This air passes the non-return valve 37 and, increasing the pressure in the line beyond valve 37, causes the indicator 38 to register the distance driven. The movement of the member 26 is of course transitory, and the member 26 is almost instantaneously returned to the normal position against the stop 28. However, the nonreturn valve 37 ensures that the indicator 38 will continue to record the distance driven, until the valve 41 is opened to bring the pressure within pipe 36 to atmospheric. As soon as the member 26 is returned to the normal position, air is drawn into pipe 36 through the non-return valve 40, permitting the cylinder 34 to return to its initial shape.

While the hydraulic-pneumatic system illustrated and described for indicating the movement of the member 26, and hence the length of the drive, has the merit of being simple and inexpensive, bearing in mind the distance between the target and the display point, other methods, particularly electrical, of measuring and displaying the displacement of the member 26 may be provided in its place, provided that the display, corresponding to the dial 38, gives a permanent indication of the impact-movement of the member 26, until reset manually to zero.

On each side of the boards 21 are two auxiliary boards an upper Rough" board 43 and a lower Bunker" board 44. Each

auxiliary board

43,44 is pivotally mounted on one of the shafts and is normally restrained in the inclined position shown by a stop 45 mounted on an upright 15, or 17. Each

board

43, 44 additionally carries a rearwardly directed cam 46 which co-operates with a micro-switch 47, so that, if the board is caused to move anti-clockwise on being struck by a ball, the cam 46 engages its switch 47 to complete an electrical circuit, which illuminates an

appropriate indicator lamp

48, 50 at the driving position. The

lamp

48, 50 remains illuminated until reset manually.

Each target board 21 additionally carries a microswitch 51, which is closed when the board is struck on a narrow central zone, which may have a width less than the diameter of a golf ball. The switches 51 are connected in parallel with a further switch 52 and with a hole-in-one indicator lamp 53. Switch 52 is closed when the member 26 is driven backwardly through a distance representing the distance of the hole" from the driving position. Thus, if a switch 51 is closed by the ball being driven accurately centrally of the target and the distance driven is correct, the circuit is completed and the lamp 53 illuminated.

Balls striking the

boards

21, 43, 44 are deflected downwardly and are directed by a deflector board 54, disposed below the level 13, towards a trough 55, where the balls are collected and eventually returned through a further trough 56 running from the target to the driving position. At the latter location, the balls may be raised automatically and one at a time to the tee 12.

The whole target, constituted by the

boards

21, 43, 44 is preferably painted to represent the fairway, rough, bunkers etc., and includes a representation of the hole itself, located on the central line of the boards 21. A series of such targets may be located side-by-side,

each with its own driving location, which may be separated from the next by walls to form separate booths, in which are located the

various display elements

38, 48, 50, 53. The various booths and targets are preferably separated from each other by nets extending from the sides of the booths to the sides of the targets.

In order to increase the similarity between the practice area illustrated in the drawings and the actual conditions on the course, the equipment may be modified to simulate all the shots from tee to pin, rather than only the initial drive. Thus, when the first drive has been made, the distance indicated on the indicator 38 may be substracted from the distance from tee to hole and the remaining distance indicated on the further indicator 60 in the booths. A second shot may be made to cover that remaining distance. When the ball has figuratively been brought within a given distance from the hole, corresponding to the usual putting distance, the hole may be completed on a putting green provided with a hole in the area between the tee 12 and the target.
