Abstract
A target shooting toy which optically projects an image of a target which can be aimed at and hit. The toy includes an image projector that projects an optical image onto a wall or screen and a toy gun which is aimed at the target. The toy detects hits by detecting light received by the gun reflected from the target. The toy has a removable electronics cartridge which has circuitry that customizes image motion, sequences and game play to the particular image being displayed. The toy also has a removable image module that contains the image or images of one type of target. The image modules and the electronics cartridges are matched so the toy may be used with many types of target images and yet be customized for use with each type of target. The projector is driven relative to two coordinates axes to provide more realistic motion and motion sequences. The toy gun has a pump action reload and trigger cocking mechanism, and provides a simulated recoil when fired.
Description




BACKGROUND OF THE INVENTION




The invention disclosed herein relates to a target shooting toy or game, and more particularly to a target shooting toy that simulates shooting at and hitting a target, particularly a moving target (e.g. skeet, duck or other moving or flying animals, airplanes, vehicles and other moving objects, etc.). More particularly, the invention relates to such a target shooting toy which displays an optical image, e.g., by projecting it to a display surface, and which determines using optics and electronics when a target image has been “hit” by a toy gun that can be aimed at the image.




There is a continuing need to produce and provide toys and amusement devices that have a high play value. With respect to target shooting toys, they should also challenge, stimulate and retain the attention of one or more players. To provide lasting play value, a target shooting toy should accommodate varying skill levels to allow players to compete at different levels and to improve their skills with continued play (e.g. co-ordination, reflexes and the like). Also, such toys should be manufactured inexpensively for mass marketing.




Various toys, amusement devices and training devices are disclosed in the following U.S. Pat. No. 2,042,174 (Foisy, issued May 26, 1936); U.S. Pat.

However, there remains a need for a target shooting toy that has one or more of the following: is relatively inexpensive and has high play; simulates target shooting games (e.g., skeet) with improved realism; is compact, can be easily set up; accommodates various skill levels; provides various types of target shooting games; is capable of single or multi-player use; provides various target images; provides improved and variable target motion; coordinates target motion with the type of target represented by the target image; provides overall versatility; provides realistic sound associated with various target images; provides competitive shooting games and practice; and other characteristics and features disclosed in the description and drawings herein. The invention herein provides a target shooting toy which has one or more of the features and characteristics described immediately above, and in one embodiment, provides all of the above features and characteristics.




SUMMARY OF THE INVENTION




It is an object of the invention disclosed herein to provide a target shooting toy which has one or more of the above described features and characteristics, particularly a target shooting toy which can be manufactured inexpensively.




The invention disclosed herein realizes certain of the features and characteristics described above in a toy which has the capability of displaying different images while providing motion, sound, and/or display sequences and/or other attributes which differ at least partially from image to image. Thus, motion and other attributes may be more closely matched with the type of target to be displayed by the toy. This may be accomplished in accordance with the invention by permanently associating with the toy that structure which is commonly used by the toy to display and move all images, or to provide audio for all images, etc., and providing in one or more user replaceable modules the remaining structure which defines and/or controls the display, motion and/or sound characteristics and/or sequences specific to one or certain images. The replaceable modules may contain electronics only, optics only, or both.




For example, images may be optically projected onto a display surface, and the replaceable module may contain electronics which causes the image to be electronically generated, and electronics which defines and/or controls the projection, display and movement of the image. In that case, the images are electronically stored. In another embodiment, the images may be optically stored in an optical format, e.g., on an optical medium such as on a film transparency, and a replaceable image module may be provided for the different stored images. One or more electronics modules may also be provided to cooperate with the image modules to define and/or control image display, projection and movement, and audio accompaniment.




In the preferred embodiment, the images are optically projected onto a display surface, and motion is imparted to the projected image(s) by mechanically coupling one or more electric motors to a structure which projects a light beam defining the optical image(s). A replaceable electronics module defines the motion parameters and/or sequences by which the motor or motors are driven, and provides control signals to a circuit or circuits not part of the electronics module which drive the motor(s). Depending upon the embodiment, the electronics module can also define and/or control sound and image display, e.g., changes in the image itself (e.g., from flying to falling, or from intact to broken-up, etc.), or displaying the image only at predetermined times in a sequence or after an event or since a predetermined time, or for predetermined periods of time, etc.




As mentioned, the images may be stored in an optical format, on an optical medium such as a film transparency, or electronically, such as in memory, and displayed on a display device. The optical format image or the image in the display device is projected by a light beam as an optical image onto a display surface. Where the images are stored in an optical format, they may be provided as replaceable modules which include one or more film transparencies or equivalent. Where the images are stored electronically, they may be provided with the replaceable electronics module or as another replaceable electronics module.




According to one embodiment, the target shooting toy includes an image projector that projects a light beam therefrom that defines an image upon impinging a display surface, a drive system for the image projector which moves the light beam, a light detector which provides electrical signals in response to light received by the light detector, a hit determining electrical circuit coupled to the light detector which determines a hit from the electrical signals provided by the light detector when light received by the light detector is reflected from an image projected by the image projector on the display surface, and a user movable device which when pointed at the display surface directs light from the display surface to the light detector. In this embodiment, the drive system moves the light beam to project an image which moves relative to at least two coordinate axes and includes at least one electrical motor carried by the housing coupled to the image projector, a first electrical circuit carried by the housing coupled to the at least one motor, and a second electrical circuit having motion-defining parameters which define the motion of the light beam from the image projector. At least one connector having a one part connected to the second circuit is removably connectable to another part connected to the image projector to removably couple the second electrical circuit to the first electrical circuit such that the second electrical circuit can be removed and replaced by another second electrical circuit having motion-defining parameters different from those of the second electrical circuit. The first and second electrical circuits cooperate to supply electrical power to the at least one motor in accordance with the motion-defining parameters of the second electrical circuit.




The motion-defining parameters of the second electrical circuit may define at least seemingly unpredictable motion of the light beam and/or varying speed motion of the light beam. The second electrical circuit may have first and second motion-defining parameters and be responsive to the hit detecting circuit defines the motion of the light beam in accordance with the first motion-defining parameters when no hit is detected and in accordance with the second motion-defining parameters when a hit is detected.




In one embodiment, the second electrical circuit includes a memory storing at least some of the motion-defining parameters and logic circuitry responsive to the memory which controls the first electrical circuit, or a programmed processor (computer). The programmed processor or computer constitutes the second electrical circuit and the hit determining circuit, and may include the memory storing at least some of the first and second motion-defining parameters.




The second electrical circuit may have a plurality of sets of motion-defining parameters, and a selector may be coupled to the second electrical circuit which is responsive to the selector to select a set of motion-defining parameters. The hit-determining circuit may be coupled to the at least one connector and may be removable as a unit with the second electrical circuit. The toy may comprise a display coupled to the second circuit which is controlled thereby to display the number of hits determined by the hit determining circuit, or other information.




In another embodiment, the second electrical circuit has parameters which define at least one attribute of the light beam projected from the image projector and can be removed and replaced by another second electrical circuit which defines the at least one parameter of the light beam differently from that of the second electrical circuit, whereby use of different second electrical circuits enables the target shooting toy to provide different images with at least one different attribute determined by the particular second electrical circuit coupled to the first electrical circuit.




The target shooting toy can also include an image module having at least one image optically stored therein which can be projected by the light beam onto the display surface. The at least one image stored by the second circuit and the at least one parameter of the second circuit are related, and the image module and the second circuit each having indicia to identify them as a related pair.




The second electrical circuit is preferably mounted in the electronics module referred to above, and the first electrical circuit is non-removably mounted to the image projector.




In one embodiment, the drive system for the projector which moves the light beam to project an image on the display surface moves the light beam (or image) relative to at least two coordinate axes. In this embodiment, the toy includes a base and the drive system includes a turret supported by the base for rotation relative to a first coordinate axis, a first electric motor mounted to the base and coupled to the turret to selectively rotate the turret relative to the first coordinate axis, a support arm fixed to the turret to which the projector is mounted for rotation relative to a second coordinate axis, a second electric motor mounted to the base and a transmission extending at least partially within the support coupling the second electric motor to the projector to selectively rotate the projector relative to the second coordinate axis, whereby the projector can be moved relative to the two coordinate axes.




A toy gun for use with the image projector may comprise a trigger and a trigger cocking mechanism which operates to cock the trigger, without which the gun can not be “fired”. The toy gun includes a trigger spring coupled to the trigger to urge the trigger to a home position. The trigger cocking mechanism comprises a manually engageable member mounted to the gun which is accessible at the exterior of the gun, and includes structure engageable by a user's hand which is movable relative to the gun. The trigger cocking mechanism also includes structure on the trigger and structure mounted to the gun which engage under action of the spring in response to motion of the manually engageable member to cock the trigger, and which disengage upon rotation of the trigger in the cocked condition thereof. A first electrical switch mounted to the gun is closed only when the trigger is cocked, and a second electrical switch mounted to the gun is closed when the trigger is pressed. The first and second electrical switches are coupled in an electrical circuit, e.g., in series, which is closed only when the trigger is pressed in the cocked condition of the trigger. The closing of the circuit may be detected to cause the circuitry to determine whether a hit has occurred, or to play sound effects, or to perform other functions.




In the preferred embodiment, the toy gun comprises a gun barrel and the manually engageable member comprises a handle mounted to the gun barrel to move therealong to simulate pump action reloading in a gun. In another embodiment, the manually engageable member may be pivotally mounted to the gun, for example as part of a trigger guard, to simulate lever action reloading of the gun. In the preferred embodiment, the cocking mechanism comprises a first slidable member mounted within the gun barrel coupled to the handle to be moved towards the trigger when the handle is moved towards the trigger, a spring coupled to the slidable member urging the slidable member towards the trigger, a first hook attached to the trigger and a second hook attached to the slidable member which engage in response to movement of the slidable member towards the trigger and release upon rotation of the trigger in the cocked condition thereof. The first switch is closed by tie slidable member in the cocked condition of the trigger.




The toy gun may simulate a recoil upon firing the gun. This may be implemented in the preferred embodiment by a second slidable member mounted within the gun barrel. The first and second slidable members each comprise a rack gear, a pinion gear rotatably mounted between the first and second slidable members meshing with the rack gears, with the above mentioned spring being coupled to the second slidable member to urge the second slidable member towards the trigger. This arrangement urges the first slidable member away from the trigger under action of the pinion gear and the rack gears, and a stop positioned along a path of travel of the second slidable member stops the motion of the second slidable member back towards the trigger while the spring exerts substantial force on the second slidable member to simulate a recoil when the trigger is pressed in its cocked condition.




The toy gun may include an electrical sound circuit coupled to the circuit closed by the first and second electrical switches which provides a gun firing sound signal in response a closing of that circuit, and/or a gun cocking sound in response to a closing of only one the switches when the circuit in which the first and second switches is connected is open.

DESCRIPTION OF THE PREFERRED EMBODIMENTS





FIGS. 1 through 14

illustrate a preferred embodiment of a target shooting toy


10


(

FIG. 1

) incorporating the invention which includes an image projector unit, or simply “image projector”,


12


(

FIG. 2

) and a user movable device or toy gun unit, or simply “toy gun”,


14


(FIG.


3


). Referring to

FIG. 2

, the image projector


12


includes a base


22


, a rotatable turret


38


mounted to the base


22


and a rotatable lamp housing or “projector”


40


mounted to the turret


38


by support arms


42


and


44


. A target shooting toy as substantially illustrated in

FIGS. 1-14

is currently being sold by Toymax Inc. under the trademark Arcadia™ electronic skeet shoot.




Referring in particular to

FIGS. 1 and 3

, the toy gun


14


is coupled to the image projector


12


by a cable


16


which is fixed to the toy gun


14


and has a connector


18


at its free end which connects to a mating connector


20


(

FIG. 2

) in a base


22


of the image projector


12


. The cable


16


includes a number of electrical conductors for power and various signals that must be transmitted therethrough, as discussed below. The connectors


18


and


20


are mating parts of a modular telephone connector. However, other connectors may be used. The image projector


12


includes a second connector


20


for coupling an optional second toy gun


14


thereto. The toy gun


14


is discussed in more detail below.




An electronics cartridge or module


60


(

FIG. 4

) is removably received in a slot


62


of the image projector base


22


and controls various functions of the target shooting toy


10


, as described below. The cartridge


60


preferably holds the second electrical circuit referred to above. An image holder or module


78


(

FIG. 2

) is removably received in a slot


94


in the projector


40


of the image projector


12


and includes images optically stored on an optical medium that the projector


40


projects onto a display surface A (FIG.


1


).




Image Projector


12


and Image Holder


78






Referring to

FIGS. 2 and 4

, the turret


38


is journalled in the base


22


for rotational movement thereof in the direction of arrow “X”, and the projector


40


is journalled in trunnion fashion to the arms


42


and


44


for rotational movement in the direction of arrow “Y”. As a result, the projector


40


is mounted for movement in two directions which, as described below, produces motion of a project image


80


on the display surface A, in two axes, i.e., the x and y axes of the Cartesian coordinate system.




Referring to

FIG. 2

, the image holder


78


, which is removably received in the slot


94


in the projector


40


, preferably holds an optical medium


87


, preferably a photographic film transparency, on which is optically stored at least first and second optically-stored images


84


and


86


. The optically-stored images


84


,


86


are spaced apart so as to be independently illuminable by a light source or sources in the projector


40


. In the preferred embodiment, projection lamps


118


,


119


(

FIG. 7

) are provided and controlled to independently illuminate each of the images


84


and


86


. The image holder


78


has an aperture


92


therein aligned with each optically-stored image. When the image holder


78


is properly seated in slot


94


, each optically-stored image is aligned with a respective a respective lamp


118


,


119


to transmit light through the respective optically-stored image and project a light beam from the projector


40


defining an image


80


,


82


(

FIG. 2

) corresponding to the respective optically-stored image


84


,


86


on the display surface A (

FIG. 1

, which shows display of only one image


80


).




The images may, for example, represent the state of a target, particularly a flying or mobile target, before and after a hit is registered. For a flying target, one image shows the target flying and the other shows the same target falling, or one image shows the target in tact and the other shows it broken-up in some fashion. In one duck shooting embodiment, one image


80


is that of a duck (

FIG. 1

) in a flying state and the other is that of the same duck (not shown) in a falling state after having been hit.




The image holder


78


includes configuration or structure for ensuring that the image holder


78


is correctly inserted and seated in slot


94


with the optically-stored images


84


,


86


aligned with a respective lamp


118


,


119


. For example, the image holder


78


may have a distinctly shaped profile


88


, a stop member


90


, and a notch


92


. The shaped profile


88


, closely mates with a similarly profile in the slot


94


in the projector


40


. The stop member


90


A substantially prevents the image holder


78


from being incorrectly inserted in the projector


40


. The notch


92


cooperates with a mating detent


96


(e.g., biased pin, shaped leaf spring and the like) that is mounted in the interior of the projector


40


for properly seating the image holder


78


therein. The notch


92


and detent


96


arrangement also ensures retention of the image holder


78


correctly positioned in the slot


94


until selective removal by a user.




Illumination of the lamps


118


,


119


is controlled by a programmed processor


70


(

FIG. 6

) in the electronics cartridge


60


. Drive circuits


97


(

FIG. 7

) for the lamps


118


,


119


are mounted on a printed circuit board


58


in the base


22


of the image projector


12


. The processor


70


also controls other functions, as described below.




Images may be provided for projection in other ways. For example, the images may be electronically stored in a memory, and video processing circuitry may be provided for causing an optical image to be displayed on a display such as an LCD. The image appearing on the display may then be projected to display surface such as surface A. Electronics for electronically storing optical images and for displaying the image on a display device such as, an LCD are known in the art and will not be described herein. Also, projecting an image from a display device such as an LCD to a display surface such as a wall or screen is also known in the art and will not be described herein.




Referring to

FIG. 4

, movement of the turret


38


in the direction of arrow “X” is powered by a first reversible electric motor


98


that is fastened to the base


22


. An output pinion gear (not shown) of the motor meshes with and drives a gear segment


100


that is formed along or attached to a selected portion of a base portion


99


of the turret


38


. The support arms


42


and


44


are mounted to and rotate with the base portion


99


, so that actuating the motor


98


rotates the base portion


99


and with it the projector


40


. Referring to

FIGS. 4 and 5

, movement of the projector


40


, in the direction of arrow “Y”, is powered by a reversible electric motor


102


, and a gear train


104


that is carried by and with the turret


38


. The processor


70


(

FIG. 6

) in the electronics cartridge


60


controls the electric motors


98


,


102


through respective drive circuits


103


mounted on a printed circuit board


58


in the base


22


.




The gear train


104


(

FIGS. 4 and 5

) is housed in the interior of the support arm


42


. The output shaft


105


(

FIG. 5

) of the gear train


104


is preferably coupled to the projector


40


by way of a clutch


106


, which allows slippage to prevent damage to the gear train and motor in the event of mishandling. The clutch


106


is preferably a tooth type for positively and accurately maintaining relative positions of the clutch halves during normal operation thereof. The engagement or meshing of the teeth is preferably maintained by a biasing spring


107


(FIG.


5


). This arrangement provides the gear train


104


and motor


102


with overload protection that allows the clutch halves to slip when the projector


40


is mishandling or misadjusted. This overload arrangement also functions as part of a manually actuated adjustment mechanism, described below, which allows a user to initially manually aim the projector


40


at a selected point along the path of arrow “Y” and in incremental angles.




In the preferred embodiment, an incremental angle in the vicinity of 30 degrees satisfies the initial adjustment needs of the target shooting toy


10


. It has also been found that the total powered movement of the projector in the “Y” direction by the gear train


104


and motor


102


combination should have an included angle within the range of 38 and 48 degrees. Preferably the range of powered movement provides an overall movement of 2.13 m (7.0 ft.) in the “Y” direction when the projection assembly


12


is positioned between 2.4-3.0 m (8-10 ft) from the display surface A.




In addition to the initial or mechanical adjustment mechanism which includes the clutch


106


, an electromechanical adjustment is also preferably provided which includes an angle select knob


108


(

FIG. 2

) that is positioned in support arm


44


. The angle adjustment knob


108


allows the user to more finely tune or adjust the position of the projected target on the display surface A. It has been found that incremental positioning steps in the vicinity of 15 degrees for the angle select knob


108


provides satisfactory results. The movement of the angle select knob


108


moves the relative positions of an up limit sensor or switch


110


(

FIG. 7

) and a down limit sensor or switch


112


(

FIG. 7

) housed therein. The up limit switch


110


and the down limit switch


112


control the extreme or ultimate extents, along the “Y” path, for electrically reversing the motor


102


. In normal operation, the up-limit switch


110


and the down-limit switch


112


only control the limits of the full range of movement of the projected image. The actual instantaneous movement or mechanical positioning parameters of the optical target image in the “Y” direction are determined by the processor


70


(

FIG. 6

) in the cartridge


60


. The angle select knob


108


includes an indicator


113


, such as an arrow, for providing a visual or sensory indication of its relative position.




The full range of movement of the turret


38


is controlled by a left limit switch


114


(

FIGS. 2

,


4


and


7


) and a right limit switch


116


that are actuated by a lug


117


selectively located on the turret


38


. However the instantaneous position of the turret


38


along the “X” path is determined by the processor


70


in the cartridge


60


. The resultant movement or lack thereof of the displayed target image on the display surface A is determined by the processor


70


.




The motors


98


and


102


for driving the turret


38


and projector


40


, respectively, are preferably of DC motors to facilitate reversal thereof. Further, a DC motor also allows for varying the speed of the motor


98


and/or


102


, which in turn may selectively move the target at varying rates across the display surface A as appropriate for the type of game being played. The combination of the variable speed control of the movement of the target image and selectable positioning parameters in either the “X” and/or “Y” direction, as provided by the replaceable cartridge


60


, challenge the skills of the user. Circuitry for providing variable speed control of the motors is known in the art and will not be described herein.




In addition to the unpredictable movement described above, the processor


70


(

FIG. 6

) is preferably pre-programmed for controlling energization of the lamps


118


,


119


. Programmed control of the lamps


118


,


119


allows target images to be either simultaneously displayed for prolonged periods as the turret


38


and projector


40


move along their respective “X” and “Y” paths, or are randomly displayed for short intervals or periods during movement or lack thereof of the turret


38


and/or projector


40


. The short periods of target display may be considered a stealth mode of operation, meaning that the projector


40


is moved while the lamps


118


,


119


are off, then either or both lamps are turned on to project one or more images to seemingly unpredictable locations for brief periods.




In order to reduce the number of or eliminate false hits from extraneous light, and to detect hits in lit (dimly) play areas, the light projected by the projector


40


is coded or modulated. In the preferred embodiment, it has been found effective to modulate the current to either or both of the lamps


118


,


119


at a frequency of between 30 and 40 Hz and to program the processor


70


to detect modulated signals in the range provided by a light detector


34


(

FIGS. 3 and 10

) mounted in the toy guns


14


. A frequency in the range of 30-40 Hz is high enough so that humans do not notice flicker in an image modulated in that frequency range, and yet low enough that the light detection circuitry does not respond to 50-60 Hz modulated light produced by conventional room lighting such as fluorescent lighting.




The image projector


12


is formed of thermoplastic material making it light-weight and compact, having a small foot print of only 25.4 cm long×22.86 cm wide×14 cm high (10 in.×9 in.×5.5 in). Its compactness and light weight allow it to be easily transported and/or stored thereby allowing its use at a selected site as and when desired.




Toy Gun


14






Referring to

FIG. 3

, the toy gun


14


includes a trigger


28


and the light detector


34


, and preferably also includes a start button


24


, a detachable stock extension


26


, a pump action reload or trigger cocking mechanism


30


, a speaker


32


and a sight


33


. The connector


18


on the cable


16


plugs into the connector


20


(

FIG. 2

) on the image projector base


22


, as discussed above.




Referring to

FIG. 11

, the pump action mechanism


30


includes a handle


160


slidably mounted to the gun barrel


162


for reciprocating motion therealong. Upper and lower rack gear members


164


,


166


are mounted within the gun barrel


162


on tracks or guides for reciprocating movement in opposite directions. A pinion gear


172


rotatably mounted between the rack gear members


164


,


166


meshes with the gears of each rack


164


,


166


so they move in opposite directions upon rotation of the pinion gear or forced by movement of one of the rack gear members. A coil spring


168


coupled to the rack gear member


166


urges it towards the trigger


28


. A lug


174


extends from the handle


160


into the barrel


162


through in elongated slot (not shown) and engages the rack gear member


166


so that the handle


166


and the rack gear member


166


move together towards the trigger


28


. Another coil spring


170


is coupled to the lug


174


and urges the handle


160


away from the trigger


28


. The end of the rack gear member


166


closest to the trigger


28


has a hook


176


shaped to engage a hook


178


attached to the trigger within the toy gun


14


.

FIG. 11

illustrates the pump action mechanism


30


in an uncocked condition of the trigger


28


, with the handle


30


in its most forward, home position.




The pump action mechanism operates as follows. The handle


160


is grasped and slid towards the trigger


28


against the action of the spring


170


, which causes the lower rack gear member


166


to move towards the trigger


28


until the hooks


176


,


178


engage, which holds the lower rack gear member next to the trigger


28


. The trigger


28


is rotatably mounted on a post


180


biased counter-clockwise by a trigger spring (not shown) mounted on the post


180


. The hooks


176


,


178


have camming surfaces which cause the trigger


28


to rotate clockwise against the action of the trigger spring until the hooks


176


,


178


engage. The trigger spring urges the trigger counter-clockwise to maintain the hooks engaged and thereby cock the trigger. In this configuration, the lower rack gear member


166


closes a leaf spring switch


154


.




At the same time, that the lower rack gear member


166


moves towards the trigger


28


, the upper rack gear member


164


moves in the opposite direction away from the trigger against the action of the spring


168


and is held there by its engagement with the lower rack gear member


166


via the pinion gear


172


.




While the trigger


28


is cocked, pressing it rotates the trigger clockwise to activate the trigger switch


152


and release the upper rack gear member


164


, which is pulled towards the trigger by its spring


170


. At the same time the lower rack gear member


166


is moved away from the trigger under action of the pinion gear


172


and the rack gears on the rack gear members


164


,


166


.




The pump action mechanism thus performs a reload function in that the switch


154


must be closed again in order to fire again and a trigger cocking function to hold the trigger cocked, as described above. (Also, as described below, closing switch


154


causes the gun to emit a gun cocking sound, and closing the trigger switch


152


while the switch


154


is closed causes the toy gun


14


to emit a gun firing sound and to provide a signal to the processor


70


.) In addition, the pump action mechanism performs a simulated recoil function. A stop


184


is positioned in the path of travel of upper rack member


164


at a point where the coil spring still exerts substantial force on the upper rack member


164


. The upper rack gear member


164


has attached thereto one or more weights


182


. Movement of the weighted upper rack gear member


164


after a trigger squeeze towards the trigger


28


under the action of spring


168


is stopped by the stop


184


while the spring


168


has considerable force so that the weighted rack gear member


164


impacts the stop forcefully to simulate a recoil.




While the light detector


34


has been shown mounted to the toy gun


14


, it may be mounted in the image projector


12


, and a light transmitting conduit (e.g., a fiber optic cable) coupled from the toy gun


14


to the light detector


34


. The toy gun


14


includes an optics assembly


190


(

FIG. 11

) including a lens


192


and an opaque conical member


194


which spaces the light detector


34


a suitable distance from the lens


92


while transitioning the larger diameter lens to the smaller diameter light detector


34


(or a light transmitting cable where one is used).




The toy gun


14


receives power from the image projector


12


via the cable


16


. However, if desired, a battery may be provided in the toy gun


14


. Also, while the toy gun


14


in the preferred embodiment is tethered to the image projector


12


by the cable


16


through which signals are transmitted by the light detector


34


and the switches associated with the start button


24


, the trigger


26


and the pump action reload mechanism


30


, signals from those devices can be wirelessly communicated to the image projector


14


(e.g., by ultrasonic, RF or infrared). Those and other wireless communication systems suitable for use here are known.

,


4


and


9


) for detecting the presence of the cartridge


60


seated therein and for controlling the application of power thereto. One non-limiting example of the interlock switch


72


is a microswitch positioned to be actuated by a cam


73


(

FIG. 2

) pivotably mounted along the edge of the slot


62


. Inserting the cartridge into the slot pivots the cam which actuates the microswitch. The cartridge


60


and the slot


62


also preferably include keying projections and slots


74


(

FIG. 2

) for ensuring proper orientation of the cartridge when it is inserted into the slot




Referring to

FIGS. 1 and 9

, the target shooting toy


10


can be powered by a low voltage power supply such as 9 V.A.C., which may be obtained from a conventional A.C. line step-down transformer (not shown, but within transformer unit


122


in

FIG. 1

) integrated with a line cord or plug for connection to a household A.C. line outlet. The transformer has a low voltage A.C. output


120


terminating in a connector (not shown) which is removably connected with a connector


76


(

FIGS. 1

,


2


and


4


) in the base


22


. The on-off power switch


54


couples the low voltage A.C. to the circuitry in the image projector


12


.




Referring to

FIG. 7

, the connector


68


accessible through slot


62


(

FIGS. 2 and 4

) interconnects the circuitry (

FIG. 6

) in the cartridge


60


and the circuitry (

FIGS. 7-9

) in the image projector base


22


. The connectors


18


(

FIG. 10

) on each toy gun


14


and the connectors


20


on the image projector base


22


connect respective terminals of the start switch


150


and the trigger switch


152


in the gun with connector


68


and the output of the light detector


34


with the respective amplifying and trigger circuit


140


(

FIG. 8

) in the image projector base


22


. The connectors


18


and


20


also connect 5 V from the image projector base


22


to the circuitry in the toy gun


14


.




The light detectors


34


(

FIGS. 3 and 10

) in the toy guns


14


in response to receiving modulated light are capable of providing a modulated electrical signal having a frequency related to the frequency of modulation of the modulated light (e.g., 30-40 Hz as discussed above). The light detector


34


is conventional and detects visible light and provides electrical output signals in response thereto. As discussed above, light modulated in the range of 30-40 Hz has been found effective for operation of the target shooting toy


10


. Therefore, the light detector


34


is selected to detect modulation of visible light at least in that frequency range. The light detector


34


may be a conventional photo transistor or photo diode. The signals output by the light detector


34


are coupled to an amplifier and trigger circuit


140


(

FIG. 8

) which includes an amplifier stage


141


and a trigger stage


143


which requires a minimum signal level to provide the amplified signals to connector


68


for coupling to the processor


70


(

FIG. 7

) as the Gun


1


and Gun


2


sensor inputs RC


0


and RC


1


, respectively. The processor


70


is programmed to count pulses in the signals on inputs RC


0


and RC


1


for a predetermined time to determine whether the signals are in the 30-40 Hz range. When a signal on RC


0


or RC


1


is detected to be within the 30-40 Hz range, the processor


70


determines that a hit has occurred. In response thereto, the processor


70


performs the game functions described herein.




Referring to

FIG. 10

, the circuitry in the toy gun


12


also includes a start switch


150


actuated by the start button


24


(FIG.


3


), a trigger switch


152


actuated by the trigger


28


(FIG.


3


), a trigger cocked switch


154


actuated by the pump action reload mechanism


30


, a sound generating circuit


156


and the speaker


36


. Pressing the start button


24


causes the start switch


150


to supply a pulse to connector


18


which is coupled to the RD


1


(or RD


3


) of the processor


70


by connector


20


and connectors


66


,


68


. Actuating the pump mechanism


30


towards, the trigger


28


cocks the trigger for firing, as described above, and provides a pulse to the sound generating circuit


156


. The trigger cocked switch


154


and the trigger switch


152


are connected in series with 5V, so that pressing the trigger


28


causes the trigger switch


152


to supply a TRIGGER pulse to connector


18


and the sound generating circuit


156


only when the trigger cocked switch


154


is held closed by the pump action reload mechanism


30


. The TRIGGER pulse generated when the trigger switch


152


is closed is coupled to the RD


0


(or RD


2


) input of the processor


70


by connector


20


and connectors


66


,


68


,. The processor


711


determines whether light detected by a light detector


34


is from a lamp


118


,


119


when a TRIGGER pulse is generated. Pressing the trigger


28


releases the pump action reload mechanism


30


and opens the trigger cocked switch


154


so that while the trigger cocked switch


154


is open, further trigger squeezes do not produce further TRIGGER pulses.




The sound generating circuit


156


(

FIG. 10

) in the toy guns


12


generates a trigger cocking sound signal in response to the PUMP pulse and a gun firing sound signal in response to the TRIGGER pulse. The speaker


32


sounds a gun cocking sound in response to the gun cocking sound signal and a gun firing sound in response to the gun firing sound signal provided by the sound generating circuit


156


.




The processor


70


(

FIG. 6

) also receives function select switch


48


activations on port RA


1


and player select switch


50


activations on port RA


2


, and activations of the limit switches


112

and


118


on ports RC


2


, RC


3


, RB


2


and RB


3


, respectively, from the image projector


12


via connectors


66


and


68


. The processor


70


provides an output to each the lamp


118


,


119


to control illumination and modulation thereof, drive signals to the motors


98


and


102


to energize them for driving the turret


38


and the projector


40


in forward and reverse directions, and outputs to the sound generating circuit


71


. The sound generating circuit


71


also provides an input to the processor


70


on port RA


3


. Outputs SG


0


-SG


12


control the display


52


, which is conventional, e.g., LED or LCD.




Referring to

FIG. 7

, conventional motor drives circuits


103


are coupled to the connector


68


to receive the forward and reverse drive signals from the processor


70


(RE


0


-RE


3


), and conventional Darlington lamp drive circuits


97


are coupled to the connector


68


to receive signals from the processor


70


to switch the circuits at the modulated frequency.




The processor


70


can be programmed by one of ordinary skill to provide the functions described herein.




Operation




Referring in particular to

FIG. 1

, the image projector


12


is preferably placed on a flat surface such as a table or the like at a distance “D” between 2.4-3.0 m (8-10 ft) from a light colored display surface A, The display surface should be free of objects in a play area “A”. In this example the display surface is in the neighborhood of 2.13 m (7.0 ft.) high by 2.13 m (7.0 ft.) wide. The size of the play area may be increased or decreased by increasing or decreasing distance “D” respectively. The transformer unit


122


is connected to the A.C. line and the low voltage output


120


is connected to connector


76


in the base


22


. The connector


18


of toy gun's electrical cable


16


is connected to the connector


20


in the base


22


.




Referring particularly to

FIG. 2

, the user initially inserts the cartridge


60


into the cartridge slot


62


followed by the insertion of the image module


78


into the projector


40


until it is fully seated. Referring now to

FIGS. 2

,


11


,


13


, and


14


the user now moves the power switch


54


to the ON position and then depresses the first push button


46


to select from the GAME options shown in FIG.


12


. The GAME option codes (e.g. −1; −2 etc.) are sequentially displayed on the display


52


until a desired option is selected. Depressing the second push button


48


makes a selection from the FUNCTION options (FIG.


13


). Each time the push button


48


is depressed the display


52


sequentially displays one of the FUNCTION codes (e.g. F


1


, F


2


etc.). After the FUNCTION code is selected, the user depresses the third push button


50


for selecting from the PLAYER codes (e.g. P


1


; P


2


etc.), shown in

FIG. 14. A

second toy gun


14


must be connected to the right connector


20


in the base


22


in order to select some of the player modes.




Selection of the GAME, FUNCTION and/or PLAYER options selects various parameters stored in processor


70


. After the GAME, FUNCTION and/or PLAYER selections have been made, the user depresses the start button


24


on the toy gun


14


. Prior to the actual staring of the game, the display


52


scrolls through the selected code for the GAME; FUNCTION and PLAYERS for review by the user. The period of play or “game end” is controlled by the processor


70


. Non limiting examples for the period of play or “game end” are shown in FIG.


13


.




After entering play and game selections, one or more players are ready to play. In the preferred embodiment, the toy gun


14


must be reloaded after each shot using the pump action reload mechanism


30


. To play and attempt to hit a target image on the display surface A, a player aims the loaded toy gun


14


at the target


84


projected on the display surface using, the sight


33


on the gun


14


. When the light detector


34


of the gun


14


is aligned to receive light reflected from the target image


80


on the display surface A, the processor


70


detects the reflected light and determines that a hit has occurred. In response to a hit determination, the processor


70


causes the lamp


118


illuminating the flying duck image at


84


in the image holder


78


to turn off and simultaneously causes the lamp


119


illuminating the falling duck image at


86


in the image holder


78


to turn on, which causes the image projector


12


to replace a flying duck image with a falling duck image. Also, after a hit, the projector


40


moves in the “Y” direction to project a vertically downwardly moving image to simulate a falling target. After a miss, a player must reload the gun


14


by using the pump action mechanism


30


.




The preferred embodiment of the target shooting toy


10


includes a speaker


56


in the image projector base


22


and a sound circuit


71


to generate a simulated sound that corresponds to the status of the moving image


80


(e.g. duck, game, airplane, vehicle, etc.) that is projected on the display surface A. For example, a quacking sound may be made when a duck is flying normally, which is replaced by whistling sound when the duck is hit and falls.




The processor


70


in each cartridge


60


is preferably pre-programmed to generate motion, motion sequences, display of images


80


,


82


, sounds, etc. suitable for the targets in the corresponding image holder


78


. Thus, the sounds may be customized to the specific targets, rather than being generic, and the motion, sequence, display etc. of the stored target images


84


,


86


may be customized for the specific image. For example, a hit duck falls vertically, while a hit vehicle may continue to a limited extent its prior motion. Thus, image holders


78


and cartridges


60


are paired, and preferably bear indicia or are coded in some way to make the different cartridges and holders easily distinguishable and pairable. For example, the image holders and electronics cartridges may be color coded or may both have the name of the image (or suitable alpha-numeric coding) or a graphic representation of the image.




Using a second optional toy gun


14


, the preferred embodiment of target shooting toy


10


of the present invention provides head to head competition between two players in the


2


P mode (FIG.


14


). In this mode, for example, the first player to hit a target wins, or the first player to hit a predetermined number of targets wins, or the player with the most hits at the end of a predetermined time wins.




Regardless of mode, scores may be checked by pressing button


50


until the player's as code appears and then reading the score associated therewith on the display


52


.
