Description

niiDoi nVspna ni&a ya †n Trolley with retractable target and shooting range comprising the same AUSTRALASIAN TRAINING AIDS PTY. LIMITED C: 39450 BRIEF DESCRIPTION OP THE INVENTION This invention relates to equipment for target ranges and to target ranges including such equipment.

Broadly the equipment comprises a trolley, which preferably is radio controlled, for moving along a track on a target range and the trolley has a controllable target mechanism which is preferably a radio controlled target mechanism. The controllable target mechanism is of the type which moves a target from an inoperative shooting position to an operative shooting position.

The inoperative shooting position and operative shooting position are defined respectively as wherein a target carried by the target mechanism is at least not substantially visible to a shooter and wherein a target carried by the target mechanism is visible to a shooter. Most preferably the target mechanism has a hit call facility and a radio hit count facility.

The width of the trolley and target mechanism and target are constructed and arranged to be substantially identical in the operative and inoperative shooting positions.

Broadly the range comprises a track along which the above 0) trolley with the controllable target mechanis is to move and wherein the track and trolley and controllable target mechanism are in use out of sight of a shooter at a firing area on the range by being in a track of width only sufficiently wide to allow the trolley to move and wherein targets are made to move from the inoperative shooting position to the operative shooting position "by being signalled by the controllable means.

Therefore according to the invention there is provided · a trolley in combination with a target carrying mechanism for use in shooting ranges wherein the trolley is movable backwards and forwards along a track, and comprises motor means carried by said trolley for propelling the same along said track, the target carrying mechanism being mounted on said trolley, there being means for swinging a part of said target carrying mechanism in a vertical plane parallel with the direction of movement of the trolley to move a target from an inoperative shooting position wherein said target is not exposed into an operative shooting position wherein said target is exposed or vice versa, the arrangement being such that, in use,the width of the trolley and target transversely of the direction of intended movement of the trolley when the target is in the inoperative shooting position is not substantially greater than the width of the trolley and target transversely of the direction of intended movement of the trolley when the target is in the operative shooting position, the arrangement also being such that when the target is in the inoperative shooting position the overall height of the trolley and target is not substantially greater than the height of the trolley.

According to a further aspect of the invention there is provided a shooting range including a trolley aa defined above, a track along which the trolley is to aiove, aaid track being of a width only sufficiently wide to allow the trolley to pass and being of a depth which when the trolley is in the track the top of the trolley will be below the depth of the track the path further bei g such that in use, the trolley and the target, when in the inoperative position, are out of sight of a shooter DESCRIPTION OF PRIOR ART Trolleys which, carry target mechanisms for moving targets from an inoperative shooting position to an operative are known. Such systems have, however, a very real disadvantage and this is particularly so when the trolleys are used on an open range wherein the targets, apart from being fired at by weapons such as rifles mortars and pistols, are fired at with large calibre projectiles such as those fired by tanks. The disadvantage is that in such ranges it is very difficult to camouflage the track. Obviously it is a requirement that the track over its whole extent be camouflaged so that a trolley carrying a target in the inoperative position can "sneak up" or move close to the shooter and the target moved to the operative shooting position thereby simulating a surprise attack, without the shooter being able to anticipate where a target is likely to appear. All systems known to date suffer from that disadvantage as in all known systems the targets have moved from the operative position to the inoperative position by swinging across the direction of intended movement of the'trolley. Thus for a target which stands 5 feet high - i.e. a target representing a soldier - the width of the trolley, target mechanism and target in the inoperative position is greater than 5 feet. This in turn means that the width of the track along which the trolley moves must be at least equal to that width. In an open range such track is easily visible even if considerable undergrowth surrounds the track.

With the present invention "because the width of the track is only sufficiently wide to allow the trolley to pass, the track can be easily camouflaged by undergrowth such as grass growing on both sides of the track or alternatively the trolley can move in a trench which is of the fractionally larger width than the track sufficient only to allow the trolley to move therein.

Most importantly the cost of installing a range, according to the present invention, is less than for known ranges as the amount of earth required to be removed to provide the trench is far less and moreover the cost of removing that earth from the range is less than would be the cost of removing the earth required for a trench required where the targets swing in the trolley as the width of the trench is much less but the depth thereof is about the same.

Further with the trolleys according to the present invention a range can be quickly set up by simply using a back hoe on a tractor to dig the trench. This is in itself far less expensive than using other machinery for digging the wider trenches for the known ranges.

Thus constructions of trolley and target mechanism specifically excluded from the invention are those which move targets from the inoperative to operative positions by swinging or otherwise moving the target across the direction of intended travel of the trolley.

One way in which the targets are moved from the inoperative to operative positions and included in the invention is by swinging the target in the plane of the target in the direction of intended movement of the trolley. This is particularly provided for when the trolley and plane of the target move generally perpendicular to the direction of firing.

Another way in which the targets are moved and included in the invention is by swinging the targets, with the plane of the target extending across the direction of intended movement of the trolley, in the direction of intended movement of the trolley. This is particularly provided for when the trolley and target are moving in a direction generally in line with the direction of firing and wherein the target faces the shooter and moves from the inoperative to operative positions by swinging or otherwise moves forwardly or rearwardly.

OBJECTS OF THE INVENTION It is one object of the invention to provide a trolley and target mechanism which in the inoperative and operative target positions have substantially the same width as the width of the trolley and mechanism thereby permitting a range to be established wherein the track is only marginally larger in width than the width of the trolley and wherein a less visible track to the shooter is presented than hitherto known. It is a further object of the invention to provide a target range which includes a trolley and target mechanism wherein the width thereof including a target carried by the trolley and mechanism has a width in the inoperative position which is substantially the same as in the operative position and is substantially equal to the width of the trolley and mechanism, and the width of the track therefore is marginally larger than that width.

DESCRIPTION OF PREFERRED MODIMENT Referring generally to Figures 1 and 2 there is shown a trolley 1 on mono rails 3 in a track which is defined by a trench 5 · The rails 3 are fabricated from tubular material and have an upper rail 7 and a lower rail 9 interconnected by spacing webs 11. The spacing webs 11 are equally spaced along the length of the rail for a purpose which will be explained later. The mono rail 3 has a vertical side height greater than its width - the diameter of the tubular material. As shown the depth of the trench 5 is sufficient so that the top of the trolley 1 is below ground level in which the trench 5 is provided and that the width of the trench 5 is only sufficiently wide to allow the trolley 1 to move freely therealong. The rail 3 is supported in the trench 5 on foundation means 13 . The trolley 1 is fabricated from metal sheet and has two platforms 15 at each end of the trolley and on one side of a central axis of the trolley. The platforms 15 support target mechanisms 17 vhich are target mechanisms of the type described in Australian Patent Ho. 276 , 215 , The target mechanisms 17 in turn carry targets 19 and include a part which can swing in a vertical plane parallel with the direction of movement of the trolley and move the targets 19 from an operative to inoperative position by radio control means. The plane of the targets 19 is in line with direction of intended movement of the trolley 1 - see Figure 2 where the targets are in the operative positio - and the targets 19 are caused to swing in their plane in the direction of intended movement of the trolley 1 - see Figure 7 where the targets 19 are in the inoperative position.

The target mechaniDms 17 are held in compartments 21 by means not shown. Night shoot devices 23 of the type also disclosed in Australian Patent Ho. 276» 15 are fitted on the top of compartments 21 and provided for night shooting.

The trolley 1 is suspended on the track 3 by a pair of driven wheels 25 and 27 which each engage the upper rail 7 - see Figures 1 and 4 - and are driven by two two speed electric motors 29 vhich are, in turn, powered by a first battery source 31 shown dotted - see Figure 2 , The trolley i3 stabilised against lateral movement across the track by two pair of jockey wheels 53 which engage the side3 of the lower rail 9 a each end of the trolley 1.

\ The trolley has a disc brake mechanism 35 - shown dotted in Figure 1 - 3hown in detail in Figures 3 , 4 , 5 and 6. The brake mechanism 35 has a disc 37 integral with the drive shaft motor 29. On each side of disc 37 there is a boomerang shaped plate 39 and 41 respectively. Both plates 39 and 41 are supported at their free ends to an inner part 43 of the trolley by means of holding means 45. Disc brake pads 47 are fitted on each of the plates 39 and 41 a positions to clamp the disc 37 therebetween as a result of braking spring pressure applied to each of the plates 39 and 41 by a pair of springs 49.

The brake is released by operation of electric solenoid 51» the plunger 53 of which pushes the two plates 39 and 41 apart when voltage is applied to the solenoid 51. Manual release of the brake mechanism is sometimes required when the trolley is stationary on the track and this is effected by operation of a manual release lever 55. Lever 55 when operated by angular rotation causes a shaft 57 attached thereto and mounted in journals 59 to rotate to in turn, cause a lever 61 integral with shaft 57 to swing to, in turn, cause an operating member 63 pivoted thereto to move downwardly.

The operating member 63 has a ramp surface defined by an inclined slot 65 and a cam surface 67. A pin member 69 on plates 41 is located in the slot 65. Downward movement of operating member 63 causes the operating member 63 to move sideways so that the cam surface 67 engages a surface of a projection 71 of plate 39 and applies pressure between pin 69 and that surface to cause plates 39 and 41 to move apart thus releasing the brake mechanism from braking spring 73 ensures the operating member 63 returns to the position shown in Figure 5 when the lever 55 is released.

The trolley has a manual control panel (not shown - on one side thereof) for controlling various operation functions of the trolley and target mechanisms 17. The electronic circuitry for controlling the trolley and the mechanism has not been shown but is carried respectively in the trolley and in the target mechanisms 17 and are each powered by a second battery source 75.

The trolley also has direction reversing switch means therein which induces magnetically operable reed switch 77.

The reed switch 77 is made operable by a length of magnetic material 79 placed at suitable positions along the length of the track. Such positions are preferably at each end of the track - see Figure 7 - but may be at any desired location. When the reed switch 77 operated connection is made to the motors 29 to reverse the direction of rotation and hence the direction of movement of the trolley.

The trolley also has proximity sensing means at each end thereof which reverse the direction of drive of each of the motors and the direction of movement of the trolley. The proximity sensing means includes an infra red transmitter 81 and receiver 83 - see Figure 2 - which is constructed and arranged so that when the receiver 83 receives an infra red light signal from either another transmitter 81 or another trolley or from a reflection of the infra red light transmitted by the transmitter 81 on the trolley and reflected back from a reflector.

The transmitter 81 consists of a light emitting diode which is triggered by an output from a pulse generator which transmits pulses of ΙΟμβ duration at a repetition frequency of 1200.

The receiver 83 comprises a photo-transistor, sensitive to emissions in the infra red wave band which is coupled to a differential amplifier.

The level of the amplifier is adjustable, thus effectively varying the sensitivity of the receiver 83. This provides a means of controlling the sensing distance between trolleys.

The output. of the receiver 83 is a.c. coupled to a switching stage which is controlled by feedback from the programmed directions of the motors.

The proximity sensing means is provided for a purpose which will be explained later.

The trolley carries electrical contact means 85, shown in detail in Pigures8, 9 and 10, which swing from an inoperative contact position to an operative contact position where they engage bus bars 87 at one end or both ends of the track and provide contact means whereby electrical energy can be applied to each of the first and second battery sources to recharge those sources. and or i he rolleys shoul pass pas e a u men ra at one end of the track.

The trolley 1 has position sensing means for enabling the position of the trolley along the track to be determined. The position sensing means is indicated generally by 110 - see Figure 2 - and comprises a reed switch which is operable to provide an electrical signal consequent on the trolley passing a track spacing member 11. Thus as the track spacing members 11 are spaced at known equal intervals along the rail 3 it is possible by counting the electrical signals provided by the reed switch to determine where the trolley is along the track. When the direction of movement of the trolley reverses a logic system of the electronic circuitry is altered so that each signal then provided is subtracted so that no matter which direction the trolley moves along the track its position can be determined.

Photoelectric position sensing means may be provided as an alternative to the reed switch means . If desired such photoelectric position sensing means may be responsive to a photoelectric beam therein which is cut by spokes in the drive wheels 25 or 27.

By inspecting Figure 1 it will be realized that the track can be manually picked up out of the trench and set up in another trench. Hence by using the above trolleys with the mono rails it is relatively easy to change the track layout of a range, as for example from one time of shooting to the next, to thus provide a variety of simulated battlefields on the one range from one time of shooting to the other. This is particularly so as the manual effort for digging new trenches in which the trolleys move, or cutting grass or like undergrowth where the track is to be is much less than in known ranges where the targets on the trolleys swing across the direction of intended movement of the trolleys.

The ranges as shown in Figures 13 to 16 will now be described before the block schematic diagram as shown in Figure 12 is referred to so that an appreciation of the practical manoeuvres the trolley can simulate can be realized. This should make the understanding of the block schematic diagram more simple.

In Figure 13 the range shown has a track 121 along which several trolleys 1 are arranged to move. The track is defined by a trench and has a mono rail 123 therein on which the trolleys as previously described are placed.

The range has a number of lanes 124 and has two firing positions shown by circles at 125 and 127 respectively.

Behind the track 121 is a mound 129 into which bullets fired on the range theoretically settle.

In use the trolleys are set moving in the track with the targets being in either the operative or inoperative shooting positions. People shooting should only shoot at 'targets appearing in their respective lane and because the targets are made to scatter by moving backwards and forwards along the track by reason of the proximity sensing means or the direction reversing reed switch 77 or by radio control means the targets represent dodging and/or appearing and disappearing targets .

A controller of the range has a transceiver which is constructed and arranged to provide instructions to the trolleys to move them one way or the other along the track or to move the target or targets carried thereby from the inoperative position to the operative position and vice versa. The transceiver also has controlling means to provide instructions to the targets to remain in the operative shooting position when hit or to move when hit to the inoperative position.

Additionally the transceiver is provided with a radio hit count facility for each target .

A shelter shed 128 for the trolleys is provided at one end (or both ends) of the track 123 for the trolleys, after shooting, and the batteries in the trolleys are recharged as previously described when in the shelter sheds.

The range shown in Figure 14 is similar to that as in Figure 13, the control functions of a transceiver operated by a controller of the range being identical. Here the difference is in that instead of there being only one track along which the trolleys move there are several placed in close proximity to each other the minimum distance between each being determined only by the width dimensions of the trolley.

The range shown in Figure 15 h s a plurality of two sets of tracks 123 extending generally towards a shooter - generally in the direction of intended shooting - and wherein the tracks each carry a target which faces the shooter and which moves a target to the operative shooting position and the inoperative shooting position by swinging the target either forwardly or rearwardly of the direction of intended movement of the trolley. The control console is the transceiver as described in the previous ranges. On a control signal being given the trolleys move and simulate a dodging target advancing or retreating.

Preferably protective mounds 124 are placed in front of each of the sets of tracks to protect the trolleys from bullets when the trolleys are in a position moving directly in line with direction of shooting.

Figure 16 shows how a simulated military battlefield can be prepared. The trolleys each are controlled by the transceiver or transmitter as previously described and by the operator or controller of the range. Obviously the tracks along which the trolleys move will be substantially non-visible as discussed before, but for the purposes of this patent specification the tracks are shown.

Referring now to the block schematic diagram of Figure 12 each component is clearly marked and the concept of operation should be readily understood from that diagram, however, a brief explanation will follow: The transceiver is the transceiver as used by the controller of the range and has multi-channel facilities for controlling each of the various functions and displays .

The receiver and transmitter are mounted in the trolley.

The receiver is powered by one of the battery sources and the motors are supplied by the other battery source.

On signals being received either from a manual control or from the transceiver or from a transmitter (not shown) to start the trolley moving the brake solenoid is energised releasing the trolley brake and the motor drives the trolley. The end of track sensors, reed switch 77» or the proximity sensors have control over the motor to reverse direction of drive.

When the target is hit , hit signals are sent via the transmitter to the transceiver for indicating the number of target hits. The position sensor is also connected with the transmitter to provide signals to the transceiver to give an indication of the position of the trolley on the track.

In a modification of the trolley described above it may be driven by electric motors powered by a trailing cable.

Alternatively the motors may be petrol motors with extra quiet silencers so that the noise of the motors will not be able to be detected by shooters thus giving a general indication of where the trolley and the targets thereon may appear.

In a modification of the ranges described above the transceiver may be controlled from a tape or similar recording media on which programs for each of the trolleys and targets have been recorded.
