This invention relates to hit scoring target systems and, more particularly, to a target arrangement therefor which is suited for use as a scoring target on a golf driving range.
Golf driving ranges are quite popular as a form of recreation and exercise since they do not require as much space as the usual golf course nor does the use thereof require the time needed to play a round of golf. In the usual game of golf the player competes with himself and the other players in terms of the number of strokes required to travel around the course. The usual practice at a golf driving range is to play for distance and in certain instances special targets are provided to test the accuracy skills of the players. For the most part, these special targets make no provision for indicating when a hit has been scored but rather, rely on the player to identify a hit by sight. This tends to make the player look at the target prematurely wit-h the result that the player may not keep his head down or develops other bad habits of play. Attempts have been made to provide hit scoring target means for use with outdoor activities but those that provide a sufficient area are usually susceptible to being activated by gusts of wind giving false hits or require the hit to be of such force to be impracticable.
It is a principal object of the present invention to provide a hit scoring target suitable for use on an outdoors golf driving range and the like, which avoids one or more of the disadvantages of prior art devices and is highly efficient.
A further object of the present invention is the provision of an improved hit scoring target system that is completely portable, is of variable sensitivity and not seriously effected by varying wind loads.
A still further object of the present invention is to provide an improved hit scoring target system which will provide any manner of desired indication of a hit being scored, is inexpensive and sturdy of construction and is easily maintained.
In accordance with the present invention, the hit scoring target system includes a target means having a hit receiving portion thereof forming an electrical contact of a switch means and another portion thereof forming another contact of the switch means, an alarm circuit having a power source and an alarm device and means connesting the power source with the alarm device including the switch means of the target means which switch means is adapted to complete an electrical path between the power source and the alarm means in response to the scoring of a hit on the target.
For a better understanding of the present invention, together with other and further objects thereof, reference is bad to the following description taken in connection with the accompanying drawing and its scope will be pointed out in the appended claims.
In the drawing:
FIGURE 1 is a view in elevation of the target arrangement of the invention;
FIGURE 2 is a view along line 2--2 of FIGURE 1;
FIGURE 3 is a view to enlarged scale, with parts broken away to conserve space of the detail of securing the target to the target holder;
FIGURE 4 is a rear view of the target; and,
FIGURE 5 is a side elevational view in cross-section of another embodiment of the target arrangement and a circuit diagram of the scoring system.
Referring now to the drawings and, in particular, to FIGURE 5, the hit scoring alarm system is seen to comprise a target arrangement 10, a power supply 12 and an alarm device 14, wherein a hit on target arrangement 10 serves to complete an electrical circuit. connecting the power supply and the alarm device to energize same and give an indication of a hit being scored.
Reference is now had to the target arrangement and a detailed description thereof since this constitutes the single most important element of the scoring system. The target 10 is seen to comprise a target holder 16 which may conveniently be made of metal and is shown to have a circular bottom 18 with an upstanding circular sidewall 20 to define a pan-like structure. A target 22 of flexible materials such as vinyl plastic, nylon and the like is supported from the sidewalls 20 in spaced relation to the bottom 18 of the target holder. The target is provided with a series of holes 24 arranged in spaced relation around the peripheral extremities thereof. As best seen in FIGURE 3 the holes may be provided with metal grommets 26 for strength. A plurality of lugs 28 are positioned around the inside of the sidewall of the holder 16 in. uniform spaced relation and a spring 30 is supported by each lug. A cord 32 of nylon and the like is passed through each hole 24 in the target 22 and through each adjacent spring 30. The ends of cord 32 are connected with a turnbuckle 34 and the like, adapted to place the cord and the attached target under tension supported in spaced relation and electrically insulated from the target holder 22.
To the back of target 22 is fastened in suitable manner, such as stiching 35, a piece of wire cloth 36 of copper or other good electrical conductor. The wire cloth may conveniently be sewn to the target. As will be seen in FIGURE 2 and FIGURE 5, the wire cloth 36 is positioned in opposed relation to the bottom 18 of the target holder 16. The wire cloth or screen 36 is seen to form one contact of an electrical switch and a conductor 38 is connected thereto for connection into a hit scoring circuit. Another conductor 40 is connected to the bottom 18 for connection to a hit scoring circuit. In FIGURE 5 another piece of wire cloth 42 is fastened to bottom 18 in opposed relation to wire cloth or screen 36 fastened to target 22. Screens 36 and 42 constitute the contacts of a switch arrangement.
Referring now to FIGURE 5, a suitable hit scoring circuit is shown to include a power supply 12 which may be a battery or where line voltage is available this may be used or transformed to a lower voltage. One side of the power supply is seen to be connected to screen 36 via conductors 44 and 38 and serially through the operating coil 46 of relay 48. One side of the power supply is also connected to one side of an alarm device 14 via conductor 44 and 50. The heater or operative element 52 of another relay 54 is connected in parallel with the operating coil 46 of relay 4%. The relay 48 is provided with a pair of switches 56 and 58 to provide a double pole-single throw switching arrangement. The poles of switches 56 and 58 are connected to the other side of power supply 12 via conductors 60 and 62 and screen 42 is also connected to the other side of power supply 12 via conductors 40, 62 and 60. Relay 54 is provided with a single polesingle throw switch and the pole thereof is connected to the contact of switch 56 of relay 48 via conductor 64. The contact of switch 58 of relay 48' is connected to the other side of the alarm device 14 via conductor 66. Relay 54 may conveniently be of the delay action type as will be explained.
In operation, when an object, such as a golf ball, strikes the target 22, the screen 36 makes contact with either the bottom 18 of the target holder 16 or screen 42 attached thereto, completing an electrical path through conductors 38 and 4-0. This completes an electrical path from the power source 12, through conductor 4-4 and the operating coil 46 of relay 48, conductor 38, screen 36, screen 42, conductor 40, and conductors 62 and 6'3 back to the power supply. On energizing the operating coil 46, relay 48 effects a closure of switches 56 and 58. When switch 58 closes, the power supply is connected to the alarm device 14 via conductors 44 and 50 and back to the power supply through conductor 66, switch 53, conductor 62 and conductor 60, energizing the alarm device. When the target is hit, it is desirable to keep the alarm device energized for a short interval but longer than the momentary contact of screens 36 and 42. For this purpose, a delay action relay 54 is provided having a pair of switch contacts that are normally closed. When relay 48 is energized, a holding circuit is completed from power supply 12 and conductor 60 through switch 56, conductor 6-4, normally closed switch of relay 54, conductor 63, through operating coil 46 of relay 48 and heater 52 of relay 54 in parallel with coil 46 and conductor 44 back to the power supply. When switch 56 closes, relay 48 is held in via the above circuit. However, heater S2 of relay 54 is energized and opens the switch of relay 54- after a predetermined time interval. Thus, when a hit is scored, the alarm device is energized and remains energized for a predetermined time interval to signal the hit.
Perhaps the most important single part of the present invention is the target arrangement. The hit receiving target for most efficient operation must be of flexible material such as a vinyl plastic material similar to that used on convertible automobile tops. The nylon cord 32 in conjunction with the turnbuckle 34 permits the tension on the target to be selectively adjusted to suit a particular set of conditions. With this arrangement, it is possible to adjust the tension on the target, to permit a golf ball to be tossed, not thrown, from a distance of about 6 feet and register a hit, while strong wind gusts will not set 01f the alarm device. This has been practically impossible to achieve with other devices which when a target of sufiicient size to be useable is provided which will respond to the impact of a tossed golf ball, is also sufficiently sensitive to wind loads to give erroneous hit indications.
While there have ben described what at preseht are considered to be the preferred embodiments of this invention, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the invention. It is aimed, therefore, in the appended claims to cover all such changes and modifications which fall within the true spirit and scope of the invention.
