that is a beam emitting gun as well as one with an in light-sensitive element provided clay pigeon is used. With this system, the clay pigeon is actually released, i. H. fired or launched, and the shooter sees the clay pigeon. Since the * light-sensitive element is provided in the clay pigeon, results in a Hit when the light beam emerging from the rifle hits the light-sensitive one Element hits. It can therefore be the so-called holding forward or forward pivoting of the rifle, which is the case in practical clay pigeon shooting required outdoors cannot be simulated using this system. Since the clay pigeon still actually flies, it is necessary to catch it or to collect it again or to rescue it.

The invention is therefore based on the object of eliminating these disadvantages and to create a simulation system for a clay pigeon shooting range by means of which the actual clay pigeon shooting is almost completely can be simulated.

The features of the simulation system created to solve this problem result from the claims.

According to the invention, a simulation system for clay pigeon shooting is provided which has in combination at least one first projector producing a visible mark, at least one second projector producing an invisible mark, a screen, at least one mirror: the visible and the invisible mark to the screen reflected, a device for three-dimensional movement of the mirror in order to move the two marks on the screen in such a way that the invisible mark is aimed ahead of the visible mark, thereby creating the h'-l i>. actual clay pigeon shooting required reserve points. to simulate.

In the laser simulation system for pigeon shooting, which can be seen in particular from FIGS. 1 and 2, a terrain representation of a landscape is generally projected onto a screen 4 by means of a suitable projector 6 arranged behind the screen or, if necessary, by means of a projector in front of the screen Screen 4 arranged projector 6 '. A visible target mark A proji / .i; Furthermore, an invisible real target mark j ^; projected on the same screen 4. The visible imaginary target mark and the invisible real target mark B move, in a special relationship to one another, on the screen 4 in such a way that they simulate the actual flight path of a clay pigeon in the clay pigeon shooting range

4 0 8 8 3 4/1 015
6461

The special relationship between the marks A and B is established by means of special relative movements of the mirror 8 as well as the respective Brands A and B associated projectors 2A and 2B are created. When the shooter, the imaginary one moving on the screen 4 Brand A has recognized correctly with a light-sensitive or light-catching Rifle 10 aims (i.e. correctly sighted over the barrel) or if he correctly "points" with this rifle 10, the muzzle of the Rifle 10 is aimed at the real mark B and it is taken from the rifle a light beam which has been reflected by the mark B on the screen 4 is collected through its mouth. If In At this moment the trigger of the rifle is actuated by the shooter, a light-intercepting device arranged in the rifle 10 also becomes actuated. When the light interception device is operated, an electrical receiver 12 and a control circuit are also operated, whereby the imaginary mark A is recognized or differentiated and at the same time at the same point at which the mark A is located Hit mark C is shown. At the same time is through a sound device 14 generates the bang of an explosion which simulates the actual explosion bang of the cartridge powder, and it can if necessary or if desired, a suitable device, which can also be arranged in the rifle 10, generates a kickback effect will.

As is clear from the above general explanation of the simulation system, the mark A sets a by bundling on the Screen 4 formed visible target in the form of an image, the one has a particular special shape and from a source of visible light, such as a xenon lamp of the projector 2A, is emitted and reflected by the mirror 8. The brand B represents an invisible target mark and is on the screen 4 as

A 0 9 8 3 Λ / 1015

Spot or point formed by, for example, an infrared laser light beam, emitted by the projector 2B and reflected by the mirror 8 is. In this case, the invisible mark B forms the effective target mark for the light-sensitive rifle 10.

The mirror 8 is supported by a suitable structure in such a way that the The angle between the mirror 8 and the projector device 2 is variable and that the trajectories of the movement on the screen 4 Marks A and B simulate the trajectory of a clay pigeon in actual clay pigeon shooting.

The projector 2A producing the visible mark A has a light source, such as a xenon lamp, as well as an iris in front of the direction, which is arranged at a front point on its optical axis is. By appropriate selection of the formation of an opening of the iris device, it can be achieved that the shape of the screen Brand A located corresponds to the shape of an actual flying clay pigeon. In the embodiment shown in FIG. 3 a Opening shape of the iris device 22, the sight mark projector 2A has a light source such as a xenon lamp containing Lamp housing 18 and a shutter or aperture device 20, which is provided at a front position of the projector 2A on the optical axis thereof. In front of the closure device 20 is also the IrIs device 22 arranged. Furthermore, an optical lens system 24 is arranged in front of the iris device 22, which the through the iris device 22 bundles of light rays passed through. The locking device 20 has a rotatable plate, not shown, which normally is held in such a position that it blocks the passage of the light rays. By magnetizing or exciting a not shown Solenoid rotates on a suitable opening signal

409834/1 01 5

the plate and lets the light through to the mirror 8. This opening signal can be, for example, a call signal from the shooter, with which he calls for the throwing of a clay pigeon, whereupon the locking device 20 is actuated by this signal via a corresponding circuit or a corresponding switch. The formation of the locking device 20 itself can be selected appropriately. Since the training is known per se, it will not be described in more detail below explained.

The iris device 22 has, as can be seen from FIGS. 4 and 5, a rotatable disk 28 with a central opening and a stationary disk 40 also with a central opening. The rotatable Disk 28 is through a slot 26 with one to the outside projecting peripheral part 28 'and provided with pegs 54, four pegs 54 being provided in the embodiment shown. the Pins 54 are arranged at the same angular distance around the circumference of the central opening of the disk 28 and protrude in the direction onto the stationary disk 40.The latter has a multiplicity of slots 52 in order to allow the curved movement paths of the pins 54, resulting from the rotation of the disk 28 to enable. Two vertical guide members 42 and two horizontal guide members 44 are attached to the stationary disk or plate 40. Means the vertical guide links 42 and the horizontal guide links are in pairs two vertical iris plates 46 and two horizontal ones Iris plates 48 supported in different ways. The iris plates 46, 48 are respectively guided uniformly in the vertical or horizontal direction by means of the guide members 42, 44. Each of the iris plates 46, 48 is inclined with one Slot 50 is provided. The pins 54 inserted into the rotatable disk or plate 28 penetrate the stationary disk or plate through their slits 52 and protrude into the end slits 50 of the iris plates 46, 48.

4 0 9 8 3 4/1015

The part 28 'of the rotatable plate 28 is looking for itself in the clock display to pivot, due to the action of a tension spring 32 between the part 28 'and one on the outer housing of the iris device 22 attached pin 30 is provided. A wire 38 is connected at one end to the part 28 ', guided over rollers 34, 36 and connected at its other end with a yet to be described viable support. Accordingly, the plate 28 when the wearable Support is shifted forwards or backwards, counterclockwise or twisted clockwise. When this happens i. H. when the plate 28 rotates, those arranged on the plate 28 perform Pin 54 curved movements. In this case, each pair of the iris plates 46 and 48, respectively, also become vertical due to the movement of the pegs 54 or moved horizontally, resulting in an iris effect. Through the inclination of the slots 52 are the movement of the J.ris plates 46,48 The distances covered and thus also the reduction in size of the opening of the iris device 22 are determined. Therefore, if the part 28 'is in the Slot 26 of the outer housing of the iris device 22 is in a position on the far left, the upper and lower iris plates 46 are In the lowest and uppermost position, while the left and right iris plates 48 are in the rightmost and leftmost positions, respectively lying position, whereby, as can be seen from Fig. 6, the maximum iris effect is achieved. If, on the other hand, the part 28 ' Located in the slot 26 in the position on the far right, the iris effect its minimum, as can be seen from FIG.

If accordingly the variable support or the basis is the Approaching projector 2A, part 28 'is gradually rotated counterclockwise; this increases the iris effect, which is a reduction the size of the brand A. This effect will used according to the invention to the perspective impression of the to simulate removing flying target. The shape of the ends of the

409834/1015

Iris plates 46, 48, d. H. the shape of that created by the iris plates 46,48 Light pattern, can be selected in a corresponding manner. However, it is always beneficial to match the shape to the actual one To adapt the shape of the flying clay pigeon. In the embodiment described, the target A projected on the screen 4 has approximately elliptical shape, which corresponds to the actual appearance of a flying clay pigeon.

Since the extent of the required lead in the actual (real) Clay pigeon shooting with the withdrawing clay pigeon or with the passing one If the flight time increases, the corresponding extent of the lead, if it is simulated on the screen 4, increases with the lapse of time Flight time from. It should therefore also include the position of the targets A and B projected by the projectors 2A, 2B among each other should be changed accordingly, i.e., the distance between the targets A and B on the screen 4 should be gradual be decreased with the passage of time. The following therefore describes the geometric and mechanical relationships between the Projectors 2A, 2B described for achieving this change in the mutual distance.

From Fig. 8, the relationship of the relative position between, the mirror 8 \ uid the projectors 2A, 2B can be seen. Here is the Projector 2A fixedly mounted on the optical axis, while the Projector 2B is rotatably or pivotably mounted at 60 on the optical axis. When the mirror 8 and the projectors 2A, 2B the out Flg. 8 have an apparent fixed relationship to each other (here it is assumed that that the mirror 8 and the projectors 2A and 2B have a common optical axis), is the one to be projected onto the screen 4 Brand A, as from Flg. 10 can be seen stationary and it is too

40983 k / 1015

the mark B stationary, as shown in FIG. 10, in the form of mark B overlaps or coincides with mark A. In contrast, when the projector 2B, as shown in FIG. 9, in A horizontal plane is rotated to the left about the pivot point 60 and then fixed in a certain position, the mark B moved to the point B of FIG. 10, while the mark A is stationary remains. If then the projector 2B is rotated counterclockwise in the direction of the arrow according to FIG. 11a and at the same time the mirror 8 is also rotated to a position according to FIG. 11a in the direction of the arrow, the marks projected onto the screen 4 become A and B displaced in the manner shown in FIG. 11b. This has a decrease in the distance between marks A and B. result in what is correct the actual distance or the actual The extent of the required lead is simulated. Since the real clay pigeon continues to fly along a parabolic path, as already mentioned, the mark A should also be moved along a parabolic path on the screen 4, which applies in the same way to mark B. Around to realize these movements of marks A, B it is necessary to to rotate the mirror 8 in a vertical plane.

Referring to Fig. 12, which shows a main mechanical part of the Symulatlonsystem, an embodiment will be described below the device for achieving these movements described.

As from Flg. 12, the projectors 2A, 2B are at one end a support rail 66 is arranged. Here, the projector 2A is attached in such a way that its optical axis largely coincides with the optical axis of a projector 2C for generating a hit mark C matches. The hit mark projector 2C projects on the screen 4 at about the in the same place where brand A is located, a suitable brand C,

409834/101 5

at the moment when the shooter catches the B mark or recorded. The projector 2B is attached to a base, the rear end of which is mounted by means of a universal joint 112. That the other end, i.e. the front end of the base is provided with a fork 110. At the other end of the support rail 66 is a Support holder 68 attached. A support table 80, which is displaceable along the rail 66, is arranged on the rail 66. At the bottom At the end of the holder 68 there is provided a horizontally extending arm 68a. A tension spring is located between the arm 68a and the table 80 106 to thereby pull the table 80 toward the arm 68a.

An arm 68b is provided approximately in the middle of the holder 68. Of the upper part of the holder 68 is provided with a pair of arms 68c and 68d. The mirror 8 can be rotated in a vertical plane by means of a device Mounted frame 76, which in turn is rotatably mounted in a horizontal plane by the arms 68c and 68d.

In a part of the frame 76, an arm 76a is provided, the sieve extends backwards.

At the left end of the rail 66, an arm 102 is provided that around a point located on the axis of the rail 66 is rotatable. When the arm 102 is twisted, the table 80 goes against the action the tension spring 106 is pushed or pushed forward.

A cam device is provided on the table 80 to rotate the mirror 8 To be able to pivot in a vertical plane. At table 80 is Means are also provided to operate the projector 2B accordingly the pivoting movement of the mirror 8 to move. education and the function of the latter two institutions are described in detail

409834/1015

explained with reference to FIGS. 13 and 14. There is also one at table 80 Pivoting device is provided, which in detail with reference to FIGS. 15 and is explained.

The wire 38, one end of which, as previously explained, is connected to the part 28 ' is connected, which in turn is part of the rotatable disc 28 of the projector 2A, as can be seen from FIGS. 3 and 4, is via a suitable Deflection roller 114 connected to table 80 at its other end. During the forward movement of the table 80 along the rail 66 due to the rotation of the arm 102, the rotation becomes ?; egg. ο foe 2ft controlled so that it controls the size of the mark A or affects. If, therefore, in the embodiment described, the table SO due the rotation of the arm 102 is displaced forward, against the action of the spring 106, the plate 28 is rotated counterclockwise and thereby the iris effect increases.

In the cam device shown in detail in FIG the main part has a pair of cam members 82a, 82b. These are how out 13 can be seen, connected to one another in such a way that they can pivot relative to one another. Here, the lower end of the connection point a suitable contact part. The free ends of the cam members 82a, 82b are each rotatable on one provided on the table 80 Projection 116 or 118 attached. The cam members 82a, 82b can be under the action of a suitable spring, for example around the junction of the cam members 82a, 82b is provided around to thereby lower the junction. The cam members 82a, 82b but can also only be pressed down due to their own weight be. The contact part provided at the lower end of the junction of the cam members 82a, 82b contacts the cam surface 120a a ring cam 120. The shaft of the ring cam 120 is with the shaft a gear 122 which is provided on the underside of the table 80 and which drives the shaft of the ring cam 120.

4098 3 4/1015

The top of the hinged cam members 82a, 82b forms a parabolic cam surface 86. This parabolic cam surface is in contact with a roller 84 located at the front end of the piston a hydraulic cylinder 90 is provided. The hydraulic cylinder 90 is attached to the arm 68b of the holder 68 in a suitable manner. From the hydraulic cylinder 90 leads a conduit 92 to a cylinder 94 which is suitably attached to the arm 76a of the holder 68 and to the front The end of its piston 96 touches the lower edge of the mirror 8.

When the cam 120 rotates, as shown in FIGS. 14a and b, the cam surface 120a of the ring cam 120 moves the joint of the cam members 82a, 82b in the vertical direction.

This means that it is assumed or assumed that the ring cam 120 is rotated by the gear 122, which may be part of a suitable transmission gear mechanism, in such a way that the connection point or the connecting part of the cam members 82a, 82b, as shown in FIG. 14a visible, lifted and then stopped. It is further assumed that the table 80 is moved in the direction of the arrow in FIG. 14a under these conditions. In this case, the roller 84 of the piston 88, which contacts the _{parabolic cam surface 86 formed by the cam members 82a 5} 82b, runs on this parabolic cam surface 86a, for which reason the piston 88 is moved in the vertical direction. The movement of the piston 88 is transmitted to the cylinder 94 attached to the frame, whereby the respective angle of position of the mirror 8 is controlled accordingly.

On the underside of the table 80 is one of the ring cam 120 corresponding Cam member 121 is provided which has a cam surface 120a of the ring cam 120 corresponding to the cam surface. The cam 121 is

409834/1015

arranged coaxially to the cam 120 and is also through the gear 122 powered. A rod 87 is in contact with the cam surface of the cam 121. The rod 87 is by means of a Supportglledesll9 pivotally mounted and is pressed against the cam surface of the cam 121 by means of a compression spring 87 '. Because of this, the rod becomes 87 controlled by the cam 121 ·. The underside of the rod 87 forms a uniform linear cam surface. At a point that corresponds to the relevant position of the cylinder 90, is in a suitable manner Cylinder 91 attached. A roller 85 provided at the front end of the piston 88 of the cylinder 91 stands with the linear cam surface at the bottom of the rod 87 in contact. Accordingly, when the table 80 is moved in the direction of the arrow, the will also be Pistons 88 assigned to cylinder 91 are driven, specifically in accordance with the gradient or the change in slope of the linear cam surface, the gradient being determined by the respective position of the cam 121 is. The cylinder 91 is connected to a cylinder 98 via a line 92b. The cylinder 98 is attached to a holder 108, the is in turn fixed at one end of a lever 78. The cylinder 98 has a piston 100 which is in contact with the lower end of the fork 110 of the support base of the projector 2B. Therefore, when the table 80 moves in the direction of the arrow, the support base becomes in accordance with the inclination of the cam surface on the underside of the Rod 87 lowered.

The relative movements of mirror 8 and projectors 2A, 2B associated with one another on the basis of the cams described can be seen from FIG. 14c. Here, when the mirror 8 is in the position 8a, the projector 2B has such a direction that it emits _{a light beam Q 1.} In this case, when the table 80 moves in the direction of the arrow, the mirror 8 is moved from position 8b to position 8c, from position 8c to position 8d and from position 8d to position 8e

409834/1 01 5

moved and then brought back into position 8a. At the same time, the projector 2B is gradually lowered so that it moves the light beam from Q to Q ₉ from Q to Q and then from Q to

Q sets up.
ο

The trajectory of the light spot obtainable in this way is shown in FIG. 14d visible on screen 4. Here, goal A becomes first

from A ₁ to A and then from A to A and finally 12 Zo

lowered from A ₀ to A. and then from A. to A_, namely

speaking of the change in the angle of the mirror 8. In the same way, the target B is moved along a path from B ₁ to B or B respectively. This means that goal B always leads goal A ahead of goal.

In the following, with reference to Fig. 15a, which the device according to Fig. 12 shows in plan view an embodiment of the mechanical part of the device for achieving the relative movements between Mirror 8 and projector 2B described. As already mentioned, that is Mirror 8 mounted by means of the frame 76, which in turn is mounted by the arms 68c and 68d and can be rotated three-dimensionally can. The frame 76 has an upper and a lower part which are rotatably received and / or received by the arms 68c and 68d, respectively. is stored. The lower end of the lower frame part 70 is here elongated and, as can be seen from FIG. 12, is bent. The free end of the lower frame part 70 is bent downwards and is received in a groove of a guide member 72. On the other hand, the as Rod-shaped holder 108 that joins the throat of the free end the fork 110 provided on the support base of the projector 2B is, as can be seen from FIGS. 12 and 13, in the already explained Manner attached to one end of the lever or the rod 78, wherein, the rod 78 is rotated in a horizontal plane by means of a pin 104 provided at a certain point along the rail 66

409834/1015

is stored in cash. The other end of the rod 78 is bent downward and engages in the groove of the guide member 72. The free ends of the rods 70, 78 can be moved in this groove of the guide member 72.

An electric motor M is provided on the underside of the support table 80 see who has a suitable transmission gear. Here is on the output shaft of the electric motor M on the underside of the Table 80 a gear 128 attached. The output shaft of the electric motor M passes through the table 80 and carries on the top of the Table 80 has a spur gear 124, this points over a certain angle its circumference on teeth that mesh with a gear 74 on which the guide member 72 is attached. The guide member 72 seeks to pivot counterclockwise due to the action of a spring 126.

When the electric motor M is rotated, the spur gear becomes 124 also rotated in the direction of the arrow. The gear wheel 74 and therefore also the guide member 72 are therefore used Set in rotation over a predetermined angle in the clockwise direction, whereupon the guide member 72 under the action of Bias spring 126 is returned to its original position. That means that the guide member 72 pivots within the predetermined angle for each revolution of the output shaft of the electric motor M will.

Assume, for example, that the guide member 72 is in the Fig. 15a has been rotated position shown in dashed lines. In this case the position of the rod 70 - and thus also the direction of the frame 76 - is not changed. In contrast, however, the rod brought into the position shown in dashed lines in Fig. 15a, which is why the optical axis of the projector 2B changes.

409834/1 015

Accordingly, the optical axis of the projector 2B becomes with each panning movement the guide member 72 within a predetermined Winkelbe rich relative to the mirror 8 moves back and forth. Which The effect resulting from this on the screen 4 is shown in FIG. 15c. Since the light source 2A is fixed in place on the support rail 66, the mark A located on the screen 4 is stationary as long as as long as the mirror 8 is also stationary. The one on the projector 2B emerging light spot changes to B when the angle between the guide member 72 and the rail 66 is greatest, but changes

when the angle mentioned is the smallest. From the-ο

For this reason, the distance between the light points A and B is dem mentioned angle proportional.

As is well known, the amount of lead in actual clay pigeon shooting should be greatest when the angle α of the direction of flight of the clay pigeon with respect to the shooter is smallest, as can be seen from FIG. 15d. If, therefore, the angle 0 of the guide member 72 with respect to the rail 66 is set in such a way that, for example, the light point B ₁ results, the provision for a flying clay pigeon is simulated, the angle α of which is relatively larger. On the other hand, if the guide member 72 is fixed such that, for example, the point B. results, the lead is simulated with a flying clay pigeon, in which the angle of the flight direction α is relatively smaller,

The gearwheel 128 of the electric motor M meshes with the gearwheel 122 via a suitable gear mechanism. The shaft of the gearwheel passes through the table 80 and is connected to the ring cam 120. Accordingly, the ring cam 120 is rotated when the motor M _{1 is} energized. When the cam ring 120 rotates, the cam members 82, 82b back and forth in the vertical direction, whereby

409834/1015

the angle of the mirror 8 within a predetermined angular range can change.

As already explained, the table 80 is under the action of the spring pulled towards the holder 68. Those against the action of the spring 106 forward movement of the table 80 is effected by means of an electric motor M which is attached to the underside of the rail 66

Ct

is. The electric motor M can use a suitable transmission gear

Mechanlsmus including a gear corresponding to the gear 124 ^ gear have, in this way, a low-speed intermittent pivoting movement of the output shaft of the Motor M to enable. The shaft of the motor M penetrates the Guide rail 66, which extends over the top of the table 80 hfnaus extending part of the shaft is connected to the arm 102. The arm 102 can be designed, for example, in such a way that it is rotated clockwise within a predetermined angular range when the shaft of the motor M rotates intermittently. at this predetermined rotational movement of the arm 102, the table 80 is pushed forward by the free end of the arm 102, whereupon dinn after the completion of the forward movement, the table 80 is brought back into its starting position by the force of the spring 106 will. This reciprocation of the table 80 controls over the Wire 38 the iris device 22 of the projector 2A.

The selective control of the motors M ^ and M is by means of a

Switch S causes. The switch S is a two-contact switch, where-2 2

when one of the contacts is closed. If accordingly a Main switch S- is closed, the motor M is rotating offset, whereby the guide member 72 is pivoted. That has result that the angle between the mirror 8 and the safe

409 834/1015

Projector 2B changes continuously and that also the cam members 82, 82b reciprocate in the vertical direction.

If then, under these conditions, the switch S by means of a still

The appropriate signal to be described is actuated, the contact a open and contact b closed. It is therefore the motor M no longer excited, with the result that the relative position of the mirror 8 with respect to the projector 2B and with respect to the height the parabolic cam surface 86 formed by the cam members 82a, 82b is, as it were, "frozen" or retained, namely to the time at which the switch S is actuated. At the same time will the motor M actuates, whereby the table 80 moves forward and that

The extent of the iris effect of the projector 2A is enlarged.

In the following, with reference to FIG. 16, due to the forward movement of the table 80 resulting relative movement between the mirror 8 and the projector 2B described.

As already explained, the arm 102 is in at the moment the position shown in FIG. 16a in which the switch S is actuated

becomes, which is why the table 80 is also stationary at this point in time. If it is assumed that at this point in time the above-mentioned "frozen" position of the guide member 72 is that which can be seen from FIG. 16a Position is also the relative position of the mirror 8 in Reference to the projector 2B Fixed as shown. the At this point in time, the mark A projected onto the screen 4 by the projector 2A is located at one point on an extension of the Rail 66, whereas the mark B projected by the projector 2B is at a position distant from mark A by P.

If then the arm 102, as can be seen from FIG. 16b, during the actuation of the motor M is rotated clockwise, the moves

Ct

Table 80 under the action of arm 102 by the distance d forward. Since at this time the angle of the guide member 72 opposite the rail 66 is fixed, the end of the moving from the frame of the mirror 8 extending rod 70 along the groove of the guide member 72 moved so that the rod end moves out on the longitudinal axis of the rail 66, which is why the holder 68 mounted frame 76 is pivoted in a vertical plane, as can be seen from Fig. 16b. At the same time, the free end of the Arm 78, which is mounted rotatably or pivotably at the pivot point 104 of the rail 66, in the direction of the longitudinal axis of the rail 66 pivoted, which is why the optical axis of the projector 2B is pivoted out of the longitudinal axis of the rail 66. For this The light spot generated by the stationary projector 2A is also shifted in the manner shown in FIG. 16b. Although the from Projector 2B generated light spot B in the same Welse with the Pivoting movement of the projector 2B is pivoted, the extent of this pivoting movement is relatively small, which is why the marks A and B on screen 4 can be moved in the same direction, their distance from one another is reduced, as can be seen from FIG. 11b.

Overall, therefore, when the motor is actuated M and due to the action of the spring 106, as can be seen from FIG. 15a, the guide member 72 is pivoted intermittently within the predetermined angular range, along with this pivoting movement, the projector 2B also pivots via the movement carried out by the end of the rod 78 will. Here, the end of the rod 78 is located in the groove of the guide member 72. At the same time, the contours of the Cams 82 and 87 changed continuously. If the switch S then

2t

4 0 9 8 3 4/1 01 5

is operated, the motor M is put out of operation. At this point in time, the position of the guide member 72 and therefore also the direction of the projector 2B is "frozen", as a result of which the flight direction of the clay pigeon to be thrown off is determined. At the same time point, the contours of the cam surfaces of cams 82 and 87 are "frozen" or retained the extent of the lead is determined or predetermined at the same time. When the motor M is actuated, which has a suitable transmission gear and is excited at the point in time at which the motor M _{1 is} stopped, the arm 102 pushes the table 80 forwards against the action of the spring 106. Due to the forward movement of the table 80, the iris effect of the projector 2A is controlled and the rollers 84, 86 run on the cam surfaces fixed or frozen at this point in time, which results in the relative movement between the mirror and the projectors 2A, 2B, as can be seen from Fig. 14d. At the same time, the guide member 72 from Flg. 16c generated relative movement of the mirror 8 with respect to the projectors. The two above-mentioned relative movements are combined with one another, which results in the trajectory of the targets A and B on the screen 4, which can be seen in FIG

As already mentioned, the target marks, i. H. the direction of launch the clay pigeon, determined by the positions of the guide guide 72 and the cams 82, 87 at that point in time, to which the table 80 is set in motion, d. H. at this moment, In which the switch S is operated. It can therefore be the shooter beforehand not be informed of the direction in which the target is launched will. That is, the destination becomes according to the timing of the operation

409834/1 01 5

of the switch S is thrown off in one of the directions shown in FIG.

The shooter recognizes what is projected onto the screen 4 in this way Aim A, and the muzzle of the rifle 10 is in the correct catfish aimed at target B if the level of conduct towards brand A is correct.

In Fig. 19 is an embodiment of that light-sensitive or Illchtauffangenden rifle 10 shown, the for the described Simulation system can be used. The rifle 10 is shown here in the form of a so-called over and under shotgun, d. H. it has two juts 130, 132 one above the other. In every run 130 or 132 is a lens system 146, a light collecting system. 148, the one captured by the lens system 146, for example Has infrared light beam responsive element, and a transmitter 150 is provided depending on the captured Light beam is actuatable. The electrical energy for the light collection system 148 and the transmitter 150 can be provided by an energy source Located in the transmitter 150, the cartridges 151 are in the usual manner shown in FIG. 20 in the runs 130,132 of the rifle 10 used. Each cartridge 152 may have a capacitor 154 that is discharged upon actuation of a trigger 142 in order to thereby enabling the electrical circuitry in the rifle to operate at the given tent. The rifle 10 continues to show in the usual catfish on a lock 136, the barrels 130, 132 with the The shaft 140 of the rifle 10 connects and can be opened or closed by means of a locking lever. It can continue if necessary or, desirably, to produce a recoil similar to that encountered when a real cartridge is fired in a rifle;

409834/1 G1 5

a mechanism comprising a pair of springs can be used for this purpose. These are cocked when the rifle is closed and relaxed when the trigger 142 is actuated, where they strike the rear end 144 of the rifle stock 140 and in this way generate the recoil.

A photodiode or the like can be used for the light interception system 148 will. The transmitter 150 is of the type that provides a fixed frequency signal in response to the actuation of the light interception system 148 generated. The electrical circuits for this and the associated electrical connections are known per se, so that they in detail not be explained further,

Fig. 22a shows an embodiment of the electrical arrangement for Creation of the Written Simulation System using the Photosensitive Rifle 10 and the others already described Mechanisms.

The circuit shown in Fig. 22a is for one embodiment intended, in which several of the mechanical devices described above are arranged side by side and a corresponding number of targets is projected onto a common screen, each of which is assigned a corresponding number of shooters. That means, that this system prevents a special shooter from mistakenly entering one Selects target assigned to another shooter; the system further prevents the special contactor in the event that the trajectories of any two or more targets on the Cross screen 4, due to the presence of a plurality of targets on the same screen, possibly one of these targets on the flight path of his own goal.

40983 ^ / 1015

For this purpose, in the arrangement according to FIG. 22a, the projectors 2B are each controlled by pulse generators in such a way that each of them generates light pulses having a specific frequency and can be delivered temporally divided by a common pulse generator. Accordingly, there is a receiving device assigned to the rifle 10 a frequency discriminator or a time division discriminator provided, to the receiving device only for the assigned Frequency signal or for one having the assigned time sequence To make the signal receptive.

The system according to FIG. 22a is an exemplary embodiment for a frequency allocation system and is operated by operating foot switches 160 provided in the respective seats for the shooters. The switch 160 is, for example, a microscope holder, and if the Contactor sits in his seat, the microswitch 160 is switched on.

When the switch 160 is closed, a motor control section 162 is actuated to throw the clay pigeon loose. As already explained, the control section 162 controls the switches S and S according to FIG. 15a. This means that since the switch S is connected to its normally closed contact and the closing of the switch 160 also closes the main switch S, the motor M is put into operation and rotated at the same time as the switch 160 is closed, the parts 72, 82 and 87 immediately begin their movements. At the same time, the projectors 2A, 2B and 2C are lit and produce the projections of the marks on the screen 4. On the other hand, however, a signal is also applied to a discriminator circuit 174 when the switch 160 is closed. The discriminator 174 receives clock pulses from a master oscillator 176. The output of oscillator 176 is also sent to projector 2B

409834/1015

Control of its light emission supplied. Although the output of the main oscillator 176 is also shared in time with the other seats for the shooters is fed, in Fig. 22a is only the first seat shown.

If the shooter then emits a call or a sound signal is generated to throw the clay pigeon loose, the voice or the sound signal is picked up by, for example, a microphone that with an acoustically actuatable circuit 180 is connected. This converts the shooter's call signal into an electrical signal that the motor control section 162 is supplied. When receiving the selection signal the section 162 actuates the switch 52, whereby the contact a is opened and the contact b is closed. The control of the projectors 2A and 2B by means of the section 162 can be more suitable Catfish, for example using electromagnetic contactor relays, can be carried out.

When contact b is closed, motor M is also stopped. However, this stopping of the motor M also changes the direction the throwing off of the clay pigeon, i.e. the light spot, is determined or determined. At the same time, the motor M is put into operation, whereby the arm 102 is rotated, which the table 80 is forwarded along the rail 66 pushes. It is therefore in the specified range Direction of the launched targets along a parabolic trajectory, which is determined by the launch direction.

The shooter detects the visible target A, holds this against by a corresponding amount with the gun 10 before and then actuates the trigger 142 of the gun 10. When the amount of co- or is correct before panning or Vorhaltens, is that of the brand B.

4098 3 4/1 01 5

of the screen 4 reflected light beam through the lens system of the rifle 10 and the transmitter 150 intercepted, which is then excited by the capacitor 154 provided in the cartridge 142, whereupon the energy source provided in the rifle is operated and via a suitable antenna device according to the frequency or the course of the tent of brand B transmits a special signal.

The transmitted signal is picked up by a receiver 172 and forwarded to the discriminator 170 of the receiving device 12. The signal to be transmitted is an explosion signal generated by the Discharge of the capacitor 154 has been generated, as well as formed from a hit signal that is captured by the light interception system 146, 148 will. The discriminator 170 generates an explosion as well a hit output, and the sound device 166 is actuated by the explosion output, whereby a loudspeaker 168 of the The bang of an explosion is generated or transmitted. The outcome of the hit of the Dlskrimlnators 170 is on the other hand the other input of the Hit discrimination switch circuit 174 supplied, which distinguishes whether the hit output of the Dlkrrimlnator 170 is assigned to the seat of the shooter. If the hit exit is correct, the hit discriminator generates 174, an output signal that the projectors 2A and 2C controls so that they distinguish the mark A and on the same Project a hit mark C at the point where mark A is located, If necessary, the output of the hit discriminator 174 can be a Circuit 184 for determining the hit probability scales.

As is known, the shot pellets contained in the shot shell scatter at a specific angle θ, as shown schematically in Fig. 22a. The range of spread of the shot therefore increases with its flight time,

409834/1015

which is why the hit probability is also reduced. To this The purpose of the circuit 184 is to determine the likelihood of hits Used in the simulation system described to simulate the tent-dependent chance of the hit probability. This means that the respective position of the target on the screen with Elapsed time detected by means of a suitable device and a A signal representative of the registered position is fed to the circuit 182.

In the circuit 182 shown in detail in FIG. 22b, a probability signal generator is composed of a time pulse generator 211, a binary shift register 212 and a plurality of end gates (in this exemplary embodiment there are ten gates). The cell pulse generator 211 generates a series of cell pulses which are registered in the shift register 212. The shift register 212 has ten digits in this case. The outputs of the respective digits of the register 212 are each connected to an input of the end gates. The output of the oscillator 211 is fed to the other input of this end gate. _{The end gate G n} is therefore opened with a first tent pulse, and it lets the tent pulses through. If a second pulse is registered in the second digit of the shift register 212, the second end gate G- is opened and allows the pulses following the first pulses through, etc. It therefore appears at the positions A _ft

to A pulse chains, each with a pulse delay with respect to y

start the previous pulse chain. This is particularly clear in Flg. 22c. As can be seen from this, the probability that at least one pulse occurs at points Α _Λ to A at any point in time during a perlode C is 100%.

U B

409834/1015

The probability that at least two pulses will occur is 90% and so on. Finally, the probability that ten pulses will appear at points A through A is 10%. It is therefore in this case, in which all gates G. to G have outputs, assuming that the probability is 10%, which is indicated by the fact that an end gate G has an output. Be in the same way the respective probabilities through corresponding outcomes

the gates G_ _o to G ₀₁ are displayed. Although in this case the probes- £ 28 L

has been chosen as running in linear form, can naturally also make a selection with regard to a non-linear probability for the aforementioned purpose.

A pulse chain is also generated by the fact that the respective The flight distance of the target with the movement of a part, such as the mirror 8 or the table 80, etc. described, is simulated. I. E. it is a part 192 which has a series of holes 190 on attached to the moving part. The part 192 has a light source 194 on one side and a photoelectric one on the other side Device 196 is arranged. The movement of the moving part is controlled by means of the photoelectric device 196 the holes 190 of the part 192 is detected. The output of the photoelectric device 196 is connected to a pulse generator 198. This generates a chain of pulses, each of which is representative of the corresponding location of the target at a given point in time Is. The pulse train becomes a shift register similar to register 212 212 '. The first pulse from the chain, which is generated first, is therefore in the first digit of the register 212 ' registered. In the same way, all positions or positions of a flight path of the target are stored in register 212 '.

409834/1 01 5

As already explained, the hit probability shows its maximum at the starting point. This maximum is the output of the End gate assigned to G. It will therefore be the outcome of the first Digit of the register 212 'together with the output of the

Gate G to the inputs of an end gate G _Λ , so that U «30

an output signal appearing at the end gate G indicates a hit in the initial stage. In the same way, the respective outputs of the register 212 'together with the outputs of the assigned gates G _Λ to G are the inputs of the end gates G ₀₁ to G

21 2 "uj Go

forwarded. The outputs of the gates G_ "to G are with the inputs an Or gate 40 connected. Its output, together with the hit output of the hit rdlskrlmlnator 174, becomes the input of a

End gate G _CA forwarded,
ου

The output of the end gate G _cn therefore indicates that the destination at a

OU

certain special spot in the correct catfish hit by the shooter and that the distribution of the shot is sufficient at this point, to destroy the target.

The output of the end gate G_ _A is fed to a time delay circuit 184, as shown in FIG. 22a can be seen. The delay circuit 184 simulates the airspeed of the shot, but in some cases this is not necessary and can therefore be omitted. The output of the delay circuit 184 is fed to the projectors 2A and 2C as in the case mentioned above.

From Flg. 23 and Flg. 24a, b, c is another embodiment of the mechanical part of the simulation system, which differs from the embodiment according to Flg. 12 differs in that the direction of movement of the table 80 'runs in the opposite direction and that mechanical connections are used instead of hydraulic connections.
