The present invention relates to toy projectile launchers and more particularly, to a rapid fire toy launch apparatus employing a feeding/anti-jamming mechanism including a simple yet unique continuous belt that penetrates a dart magazine releasing each dart from the magazine and simultaneously employing protrusion elements at the belt advancing each released dart into an energy generating mechanism for rapidly firing darts from the toy apparatus without mis-fed darts jamming up in the launcher.
Projectile launchers/shooting mechanisms are well known in the art and include mechanisms for launching toy darts, balls of various sizes, paint balls, etc., and even paper money. Various toy launchers/guns known in the art employ a projectile shooting mechanism made up of two opposed rotatable wheels (known as a drive or fly wheels) which engage a dart or other various balls and projectiles there between. A motor drives rotation of one or both wheels creating a launching force frictionally applied to the dart/projectile as the dart/projectile engages a wheel surface on each of the opposed rotatable wheels. The rotating wheels impart sufficient energy to the dart/projectile to launch the dart/projectile from the gun/shooter or hopper.
Some known methods/mechanisms for feeding darts into a drive or fly wheel or other energized launching mechanism includes advancing mechanisms actively pushing darts or projectiles into an energized launching mechanism or, alternatively, mechanisms which remove physical barriers from a path or channel leading to a launching mechanism. None of the known feeding mechanisms however, employ a continuous belt which penetrates a dart magazine to release each dart while at the same time employs one or more protrusion elements at the belt to advance each released dart in a rapid fire, anti-jamming manner, into the launching mechanism.
Various known feeding mechanisms employ rods, pistons or hammers which actively push darts into an adjacent launching mechanism. Feeding mechanisms are known to include an elongated arm biased into contact with a stack of darts lined up adjacent a drive wheel. The arm is biased into contact with the upper most dart of the stack and urges the lower most dart into the barrel adjacent the drive wheel. A biased trigger and hammer arrangement push the dart through the barrel and into the drive wheel for firing the dart when the trigger is pulled.
Also known is a trigger lever which rotates when pulled, translating into movement of a bullet pusher to advance a bullet toward rotating projector wheels which then fire the bullet. The bullet pusher can be motorized to advance bullets faster as the trigger can activate a motor to drive the bullet pusher in a reciprocating manner firing bullets in a rapid fire manner. Other known feeding mechanisms remove physical barriers from a path leading to a launching mechanism and are known to include a biased trigger, that when depressed, removes a barrier and allows a dart or projectile to enter a launch channel for engagement with rotating flywheels or drive wheels to project the dart.
Other known mechanisms utilize a belt surface to elevate or transport projectiles or balls to a launching mechanism or to shoot projectiles such as paper money from a gun. It is known to employ a belt surface with multiple holders that separate the belt surface into compartments so as to carry multiple balls, each ball in its own individual compartment, along the belt surface from a hopper to the launching mechanism. This individual arrangement of balls on the belt surface allows for the feeding of only one ball at a time into the launcher mechanism, even though multiple balls travel together from the hopper to the launcher mechanism.
Also, it is known to dispose a conveyer belt between two conveyor belt drive wheels and dispose a stack of paper currency onto a surface of the belt. Movement of the belt forces sheets of paper currency out a currency exit slot of a gun. Additionally, it is known to secure darts to a belt surface, by storing each dart in its own bracket on the belt. The belt travels through a launcher housing where motorized flywheels lift each dart from its storage compartment and launch each dart from the housing.
Significantly, known toy launchers do not include a feeding/anti-jamming mechanism that penetrates a dart magazine feeding darts into an energy generating mechanism for rapidly firing darts from the toy apparatus without the hassle of mis-fed darts jamming up in the launcher. It is desirable to provide a continuous belt slightly pressing through lips of a dart magazine to reliably release each dart while at the same time employing one or more protrusion elements continually progressing with the belt to advance each released dart into the pathway of an energy generating mechanism.
The present invention addresses shortcomings of the prior art to provide a toy launch apparatus which extends a feeding/anti-jamming mechanism into a dart magazine releasing and feeding darts into an energy generating mechanism for rapid fire launching of darts from the apparatus without darts jamming up in the launcher. A continuous belt, including one or more protrusion elements at the belt, penetrates lips of the dart magazine slightly pressing on each uppermost dart reliably releasing the dart from the magazine while at the same time activating one of the belt protrusions to advance each released dart into the pathway of the energy generating mechanism.
In one embodiment of the invention, the toy launch apparatus includes a housing assembly, a dart magazine inserted into the housing assembly and having an open end and including retaining lips at the open end, one or more darts loaded into the dart magazine, each dart including a rear advancing surface and a biased advancing mechanism at the dart magazine urging loaded darts toward the open end of the dart magazine. A continuous feeding mechanism is coupled to the housing adjacent the inserted magazine and penetrating the dart magazine at the open end, an energy generating mechanism is in communication with the continuous feeding mechanism, and a motor is driving rotation of the energy generating mechanism.
First and second gears are positioned in parallel relationship to one another and each is including a notched circumferential surface, a second motor at the housing is driving rotation of at least one of the first and second gears.
A continuous belt is stretching between first and second gears and having a first surface including teeth for engaging the notched circumferential surfaces for driving rotation of the belt with rotation of the first and second gears, and a second surface of the belt riding along an uppermost dart disposed in the magazine at the open end urging the dart from contact with the retaining lips of the magazine and into a releasing position. A biasing plate is disposed between first and second gears adjacent the belt and biasing the belt to penetrate the magazine at the open end, and one or more protrusion elements are at the second surface of the belt penetrating the magazine at the open end and engaging the rear advancing surface of the uppermost dart disposed in the releasing position into the energy generating mechanism rapidly firing the dart without it jamming in the toy launch apparatus.
For the purpose of facilitating an understanding of the inventions, the accompanying drawings and description illustrate preferred embodiments thereof, from which the inventions, structure, construction and operation, and many related advantages may be readily understood and appreciated.
The following description is provided to enable those skilled in the art to make and use the described embodiments set forth in the best modes contemplated for carrying out the invention. Various modifications, however, will remain readily apparent to those skilled in the art. Any and all such modifications, equivalents, and alternatives are intended to fall within the spirit and scope of the present invention.
A toy launch apparatus 10, as seen in
The dart magazine 16, as shown in
The machine gun type dart magazine 16 holds 25 or more darts in a circular drum and advances retained darts to an open end 18, as seen in
Additionally, the open end 18 of the machine gun magazine, as seen in
The lips 20 do not touch each other as they extend and curve beyond the open end 18 leaving a gap 20a between distal ends of the two retaining lips 20. The uppermost dart 17 in the magazine slightly bulges through the gap 20a until the magazine is inserted into the housing assembly 12, where the feeding/anti-jamming mechanism 24 urges the dart 17 from the retaining lips, as discussed in further detail below. The dart advancing mechanism 15 creates the force that bulges the uppermost dart 17 into the gap between the retaining lips 20. The dart advancing mechanism 15 advances the retained darts through the magazine and the retaining lips 20 prevent the dart advancing mechanism 15 from pushing the uppermost dart out of the open end of the magazine.
The dart advancing mechanism 15 can include a spring biased platform 22, as seen in
The darts 17 are generally manufactured from a foam material and include a first end 17a and a second end 17b, as best seen in
A continuous feeding/anti-jamming mechanism 24, as seen in
In the present described embodiment, the second pulley 28 is coupled to a gear train 36 linked to second axel 34 and driven for rotation by a motor 38. One or more gears of the gear train 36 ride on second axel 34 adjacent second pulley 28, driving rotation of second pulley 28 in a continuous fashion as long as motor 38 is activated. Additionally, in the present described embodiment, first pulley 26 is an idler pulley that rotates though a linkage with second pulley 28 as motor 38 drives rotation of second pulley 28. A continuous belt 40 becomes the linkage between idler pulley 26 and second pulley 28.
Continuous belt 40 extends between first and second pulleys, 26 and 28, respectively, linking idler pulley 26 with second pulley 28, as seen in
The belt 40 includes first and second belt surfaces, 40a and 40b, respectively, as seen in
The belt 40 is generally circular, as seen in
In the present described embodiment, the teeth 42 are also manufactured from nitrile butadiene rubber and are integral with the belt. It is also contemplated that the teeth can be made from an alternative rubber or plastic material and that the teeth could be coupled to the belt. The nitrile butadiene rubber material of the teeth 42 provides the necessary strength, firmness and flexibility required to engage the notched circumferential surfaces of the first and second pulleys while maintaining their shape and integrity during long term use without breaking down or breaking off from the belt. Also, the rubber material of the teeth, of the present described embodiment, provide additional friction between the teeth and the notched surfaces of the first and second pulleys such that the teeth grip the notched surfaces without slipping or dislodging the belt from either gear.
As mentioned above, the rubber belt 40 is sufficiently flexible to be urged or biased into the inserted dart magazine at the open end as the belt is rotated around first and second pulleys, 26 and 28, respectively, as seen in
One or more protrusion elements 46 are disposed at the belt 40 at the second surface 40b, as seen in
In the present described embodiment, two protrusion elements 46 are integral with the belt 40 at the second surface 40b, and are spaced 180 degrees apart from each other, as seen in
It is important that the protrusion elements 46 do not prematurely advance the darts from the magazine into the energy generating mechanism, but rather advance the darts only when the uppermost dart is correctly positioned for optimal launching from the launch apparatus thus preventing the darts from being mis-fed into the energy generating mechanism and jamming up in the launcher. The feeding/anti-jamming mechanism 24 provides a positioning and timing correction to the release and advancement of darts from the magazine into the energy generating mechanism to significantly reduce the incidence of darts jamming up in the toy launch apparatus. The feeding/anti-jamming mechanism 24 is designed to reliably release the uppermost dart from the retaining lips of the inserted magazine and simultaneously time the advancement of the released dart into the energy generating mechanism. In the present described embodiment, the continuously rotating belt 40 urges the uppermost dart 17 into a releasing position while at the same time rotating protrusion elements which simultaneously time the advancement of the correctly positioned released darts.
Darts 17 advance through the magazine as the advancing force from the dart advancing mechanism 15 is exerted against the darts loaded in the magazine. Darts pop up one by one into the retaining space or open compartment 21 between the retaining lips 20 before being advanced into the path of the energy generating mechanism. As the darts pop up into the open compartment 21, the heavier dart tip 19 is slightly tilted toward the magazine and lags behind the foam dart (body) when advanced into the compartment 21. If the dart is advanced or travels from the magazine while still in this slightly tilted position, the dart will not correctly feed into the energy generating mechanism and will jam up inside the launcher. This is especially likely to occur when darts are rapidly advanced into the energy generating mechanism from the dart magazine for rapid fire launching of darts from the toy.
In the present described embodiment, the feeding/anti-jamming mechanism provides reliable positioning and timing of darts advanced from the magazine to the feeding/anti-jamming mechanism, eliminating darts misfiring from the toy launch apparatus. The feeding/anti-jamming mechanism is automatically designed to wait until darts are correctly positioned before feeding the darts into the energy generating mechanism, while at the same time continuously running the mechanism. The rotating belt 40 is uniquely designed to both run continuously to urge the uppermost dart to a releasing position, and also essentially wait to feed darts into the energy generating mechanism until the uppermost dart in the magazine is in a correct (essentially level) position, as discussed above.
The belt surface 40b is too slippery to grab the dart 17 and prematurely advance it into the energy generating mechanism, but rather, the belt glides across a dart residing in the compartment 21 of the magazine and urges the dart away from the lips 20 of the magazine while leveling the dart tip 19 with the foam dart body 17, correctly positioning the dart for advancement into the energy generating mechanism. Additionally, the low profile and flexible constitution of the protrusion elements 46 allow the protrusion elements to travel across the dart surface 17d, as seen in
In use, a first trigger 50, as seen in
Additionally, the user depresses a second trigger 58, as seen in
In the present described embodiment, the feeding/anti-jamming mechanism 24 is contained within a clam shell housing 64, as seen in
A sliding lock 68 is disposed at the second side 64b of the clam shell housing 64 and is in a locked position to maintain the housing 64 and contained feeding/anti-jamming mechanism in proper engagement with the dart magazine and other presently described mechanisms of the toy launch apparatus. A limit switch 70 is closed/inactivated when the sliding lock 68 is in a locked position maintaining a proper connection between the motors 38, 51 & 53 and a power supply to keep the motors running, as seen in
A second limit switch 72, not seen in
A soft barrier 74, as seen in
Additionally, in the present described embodiment, it is desirable keep the distance between the axel 32 of the first gear 26 and the entrance 76 into the energy generating mechanism to 51 mm or more, as a safety precaution to keep small projectiles (typically less than two inches) out of the energy generating mechanism and fired from the toy launch apparatus. Projectiles less than 51 mm will not be long enough to stretch the gap between the feeding/anti-jamming mechanism and the energy generating mechanism, and will fall to the interior of the housing 12 without ever being fired from the toy launch apparatus.
While a particular embodiment of the present invention has been shown and described, it will be obvious to those skilled in the art that changes and modifications may be made without departing form the invention in its broader aspects. Therefore, the aim in the appended claims is to cover all such changes and modifications as fall within the true spirit and scope to the invention. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only and not as a limitation. The actual scope to the invention is intended to be defined on the following claims when viewed in their proper perspective based on the prior art.
