DETAILED DESCRIPTION OF THE EMBODIMENTS
(9) 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.
(10) A toy launch apparatus 10, as seen in
(11) The dart magazine 16, as shown in
(12) 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
(13) Additionally, the open end 18 of the machine gun magazine, as seen in
(14) 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.
(15) The dart advancing mechanism 15 can include a spring biased platform 22, as seen in
(16) 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
(17) A continuous feeding/anti-jamming mechanism 24, as seen in
(18) 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.
(19) Continuous belt 40 extends between first and second pulleys, 26 and 28, respectively, linking idler pulley 26 with second pulley 28, as seen in
(20) The belt 40 includes first and second belt surfaces, 40a and 40b, respectively, as seen in
(21) The belt 40 is generally circular, as seen in
(22) 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.
(23) 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
(24) One or more protrusion elements 46 are disposed at the belt 40 at the second surface 40b, as seen in
(25) 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
(26) 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.
(27) 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.
(28) 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.
(29) 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
(30) In use, a first trigger 50, as seen in
(31) Additionally, the user depresses a second trigger 58, as seen in
(32) In the present described embodiment, the feeding/anti-jamming mechanism 24 is contained within a clam shell housing 64, as seen in
(33) 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
(34) A second limit switch 72, not seen in
(35) A soft barrier 74, as seen in
(36) 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.
(37) 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.
