4 iaims. (Cl. 124-47) The present invention relates to a toy gun, particularly to the trigger of a toy gun of the type using a spring to power a projectile.
The new trigger has a portion of it designed so as to apply direct pressure on a striker means to discharge a ball projectile, in such a way that the striker means is moved into strike position in synchronization with the movement of the trigger, while the new stopper means provided either integrally on the trigger or separately but interlockedly in motion with the trigger, for stoppage or check of the ball, accompanies the trigger in motion, thereby making it possible to `achieve a remarkable increase in the initial speed of the ball, increased range, improved linearity of trajectory and increased accuracy, as well as the production of toy guns which simulate the discharge of true ones in action and effect.
In the prior art, some toy guns simply employ a powder to effect a discharge noise, and some use a spring means to propel a ball. Those which discharge balls are more interesting and more in demand. However, in discharging balls by means of an impelling spring, it is impossible to secure an undisturbed long-range trajectory, unless the release of the spring driven striker is synchronized with the release of the ball positioning stopper. If the ball is struck by the striker means before it is completely released from check, the stopper resistance may give a loss to the impelling force; and if the ball lies released from check before the striker means starts to strike, the ball may be displaced from the most effective striking position, causing the striker means to contact the ball projectile with less than its full force, i.e. the full effect of the impelling force is not transferred to the ball. Despite the presence of an important relativity between the strike action of the striking means for the ball and the position of the ball as the strike action takes place, the prior art indicates no further development than the simple use of a spring means as such, and fails to show any further studies on this point; nor has there been any practical improvement in performance, so that the range is still poor and the stopper means for the ball causes frequent trouble and inaccuracy.
The present invention removes such defects mentioned in prior art toy guns, by designing the trigger to directly press on the striker means and simultaneously withdraw the stopper. The pressure action on the trigger is integrally bound with the functional action of the striker means, thereby perfectly synchronizing the moments when the trigger reaches its final position and when the striker means is moved to its final strike position. Furthermore, in accordance with the invention, the stopper means, provided either integrally on the trigger, or separately but interlockedly in action with the trigger, perfectly synchronizes the moment when the release of the ball from check occurs with the moment when the striker acts on the ball, so that it becomes possible for the striker means to strike the ball with its maximum striking force free from any checking resistance, thus increasing initial speed, range and accuracy. Such design in accordance with the invention, has such additional advantages as economic production, reliability and a decrease in mechanical trouble.
Consequently, one of the objects of the invention is to provide a trigger for a toy gun, one portion of said trigger being designed to press on the striker means and another portion provided with an integral stopper means for stopping or checking the ball.
Another object of the invention is to provide a trigger for a toy designed such that a portion of the trigger is made to press on the striker means, and a stopper means for ball which is separately provided from the trigger, made to release the ball in an interlocked action with the trigger.
Another object of the invention is to provide a trigger for a toy gun designed such that said trigger and the striker means are pivotally rotated.
Some forms of embodiment of the invention have been set forth in the following description in conjunction with the appended drawing, in which FIGURE 1 is a side view of one embodiment of the invention having the rotary trigger provided with an integral stopper for a ball in a toy gun;
FIGURE 2 is a wide view of another embodiment of the invention having the rotary trigger provided with a separate stopper for a ball in a toy gun.
Referring to FIGURE 1, trigger 11 rotates on pivot 1d, behind the trigger is provided striker lever 12, which rotates on pivot 1'7, and these elements are energized for discharge by an unillustrated spring means. Trigger 11 has at its hinder portion an integral protruding boss 13 which lies in contact with and presses on striker lever 12. The trigger has another portion, beside that for pressure boss 13, an integral stopper 14 for ball A. Referring to FIGURE 2, stopper 14', distinct from the embodiment in which stopper 14 is integral with the trigger 12 as in FIGURE 1, is a separate element from trigger 11', rotates on pivot 18, has a portion of itself engaged with integral interlocking shoulder 15 of trigger 11 and works interlockedly with the trigger in action as it rotates on pivot 16.
In both FIGURES 1 and 2, reference number 29 designates a magazine for balls A; 30 designates a feed hole which feeds the balls downwardiy one at a time; and 31 designates the bore of the gun through which the ball is discharged. In both forms of the invention, but as seen in the FIGURE 1 embodiment, trigger 11 is pulled to rotate on pivot 16 and press on striker lever 12 with its pressure boss 13, so that striker lever 12 rotates back- Wardly on pin 17, and stopper 14 is displaced out of en* gagement with ball A as the trigger continues rotation; at the final stage of pulling trigger 11, pressure boss 13 and striker lever 12 are disengaged, and the latter is restored to its original position by its own actuated spring means, strikes ball A; nearly simultaneously stopper 14 is removed and ball A, free from any checking resistance, is struck and discharged by striker lever 12. The embodiment illustrated in FIGURE 2 is distinguished from the form illustrated in FIGURE 1 by stopper 14', which is separate from and engaged with trigger 11 by interlocking shoulder 15 and it is released by interlocking shoulder 15 and is thereby displaced from its check of ball A simultaneously or nearly simultaneously with the moment when striker lever 12 strikes the ball.
As is clearly illustrated in each embodiment of the invention, the clearing action made by stopper 14 (14'), which prevents ball A from rolling away from its strike position, and the striking action made by striker lever 12, are synchronized to a very satisfactory extent, which renders it feasible to formulate a basic design allowing the most effective impact upon the projectile. lf the action of the trigger 11 (11') is perfectly synchronized with the reverse rotation of striker lever 12 by integral pressure boss 13, an integral portion of trigger 11 (11'),
sponsor E the provision of said trigger with an integral stopper 14 or separate but well interlocked stopper 103 prevents the ball from rolling forward from strike position before release from check prior to strike by the striker lever 12 or to be struck by the striker 12 while held in position by stopper 14 (14'). The strike of ball A, when the ball is released from check simultaneously or nearly simultaneously as it starts to roll free, by striker lever l2, which rotates with a considerably greater speed than the rolling ball A, with its full force and with no preventive force, despite the possibility of negligible displacement of ball A from strike position resulting from rolling, provides a perfect strike. This insures the increased initial speed of the ball, the augmented range, the improved linearity of trajectory and the increased accuracy. In addition, the manufacture is simplified by the requirement of only two or three moving parts; a trigger, a stopper, and a striker.
Preparation for a strike and discharge of ball A in a single continuous action by a single stroke of pulling trigger 11 (11') makes it possible for a toy gun to deliver, what has heretofore been held impossible, a rapid and continuous discharge of balls with such an effective performance-that the similiarity with real guns stimulates much interest in such toy guns. It is clearly noted from the above description that the provision of a stopper integral with the trigger itself proves very elective in obtaining synchronized action; however, the same effective action and performance may be secured by the provision of a stopper 14', separate from the trigger but acting coordinately with it by assigning a suitable shape and position. Any other modified form of the invention other than those herein described may be of course possible without departing from the spirit of the present invention,
What I claim is:
ll. A trigger mechanism for a toy gun of the type having a magazine for projectiles, a barrel, a feed hole for feeding projectiles one at a time from the magazine to the 4. barrel, and a spring biased, pivotally mounted striker, actuated by movement of the trigger for striking projectiles in the barrel, the improved trigger mechanism comprising;
(a) a movable trigger, carried by the gun,
(b) means interrelating the trigger and spring biased,
pivotally mounted striker to move the striker in response to the action of the trigger, and to allow the trigger to release the striker on normal movement of the trigger,
(c) a movable projectile stopper normally positioned in the feed barrel to positively stop and hold the projectile in a stationary predetermined position in front of the striker, l
(d) means interrelating the projectile stopper with the trigger and hence with the striker such that the stopper will release its positive hold on the projectile during movement of the trigger simultaneously and in synchronism with movement of the striker in striking and propelling the projectile.
2. A trigger mechanism for a toy gun as defined in claim i wherein the trigger is pivotally mounted in the gun.
