DETAILED DESCRIPTION OF THE EMBODIMENTS

(10) The following description is provided to enable those skilled in the art to make and use the described embodiments set forth in the best mode contemplated for carrying out the invention. Various modifications, equivalents, variations, and alternatives, however, will remain readily apparent to those skilled in the art. Any and all such modifications, variations, equivalents, and alternatives are intended to fall within the spirit and scope of the present invention.

(11) FIG. 1 is an isometric view of an assembled blaster 10 pneumatic launching toy with a structural side housing 12 and structural muzzle housing 14. On the top there is a magazine or hopper 16 embodiment employing a gravity fed top hopper for rounds with triggering mechanisms. The trigger assembly 18 has two linkages that the user interacts with a cam follower linkages conveyor 18c of trigger 18b which is used to fire gel rounds with a functional lock switch 18a that activates to prevent the trigger from retracting. FIG. 2A shows an exploded view of the blaster 10 with an internal firing mechanism 20 subassembly. The firing mechanism subassembly 20 is not exploded in FIG. 2A. FIGS. 2B, 2C, 3C, 4C, 5C, 6C, 7C show exploded views of the firing mechanism 20 enabling toy projectile rounds 40 to enter the pre-firing area 20e, with pneumatic launching functions performed by an air compression element 20s with a cylinder 20h and piston 20k. The side housing includes the right proximal housing 12a, right middle housing 12b, right grip housing 12c, left grip housing 12d and left proximal housing 12e. The muzzle housing 14 includes the middle muzzle housing 14a, right muzzle housing 14b and left muzzle housing 14c.

(12) The hopper 16 has a hopper lid 16a, and two internal areas: magazine back tray 16b and magazine front hopper 16c (not shown in FIG. 2A). These internal areas hold gel rounds and are separated by magazine separator 16d. The function of the different trays are described in more detail in FIGS. 8A, 8B, 8C. Trigger 18 contains a lock switch 18a, a trigger 18b and a conveyor 18c. Trigger 18b and conveyor 18c are part of the same integral component and are constrained to move in the longitudinal axis. Conveyor 18c attaches to the cylinder cam follower linkage 22 and piston cam follower linkage 26. Trigger lock linkage 18f latches onto the conveyor 18c when the lock switch 18a is activated and the trigger 18b is fully advanced. Trigger lock spring 18e is a spring that applies a biasing force on trigger lock linkage 18f. Returning trigger 18d is a torsion spring that applies a biasing force on the trigger 18b. Finally, firing mechanism 20 controls the firing of the gel round.

(13) FIGS. 2B and 2C show an exploded view of the firing mechanism 20. The firing mechanism is responsible for enabling a gel round to enter the pre-firing 20e area, sealing a gel round in the pre-firing 20e area and firing the gel round. These functions are performed by the air compression element 20s and piston 20k. The air compression element 20s and piston 20k are constrained to move along the longitudinal axis by the firing mechanism housing. Both the air compression element 20s and piston 20k each have a cam follower linkage which controls their movement along the longitudinal axis. The air compression element 20s is responsible for opening and closing the entryway to the breech 20d. The piston 20k is responsible for firing the gel round. The firing mechanism is contained within the left firing mechanism housing 20p and the right firing mechanism housing 20q. Pre-firing area 20e holds the gel round prior to being fired. The pre-firing area 20e includes the breech 20d and the alignment passage 20x. The gel round enters the alignment passage 20x through the breech 20d. When the gel round is fired, the gel round is propelled into the projectile launching barrel 20c through the barrel seal 20t.

(14) The air compression element 20s includes the breech bolt 20a and the cylinder 20h. When the air compression element 20s is in the advanced position, the breech bolt 20a extends into the pre-firing area 20e. The extension of the breech bolt 20a into the pre-firing area 20e blocks the breech 20d. Blocking the breech 20d prevents the gel round from exiting the pre-firing area 20e through the breech 20d and prevents additional gel rounds from entering the pre-firing area 20e. The breech bolt 20a has a distal end 20u and a proximal end 20v. The proximal end 20v is at the cylinder 20h. The breech bolt seal 20b attaches to the breech bolt distal end 20u. The gel round is held between the breech bolt seal 20b and the barrel seal 20t prior to firing. The distal end of the breech bolt 20u and the breech bolt seal 20b have a channel for fluid communication 20w with the alignment passage 20x. Since the inside of the cylinder 20h has fluid communication with the breech bolt 20a, the inside of the cylinder 20h has fluid communication with the alignment passage 20x through the fluid communication channel 20w. Air compression element 20s slidably receives the piston 20k.

(15) The piston compresses the air within the air compression element 20s by rapidly sliding into the cylinder 20h. Since the inside of cylinder 20h has fluid communication with the breech bolt, if the cylinder 20h rapidly receives the piston 20k air will be rapidly expelled through the fluid communication channel 20w and the gel round will be pneumatically launched through the barrel 20c. The piston seal 20j attaches to the distal end of the piston 20k. The piston seal 20j reduces the friction when the cylinder 20h slidably receives the piston 20k. The outside of the piston 20k does not contact the inside of the cylinder 20h. Instead, the piston seal 20j contacts the inside of the cylinder 20h. The piston seal 20j reduces friction because it is lubricated. Piston seal 20j contacts the inside of the cylinder 20h to increase the air pressure inside the air compression element 20s during firing. Likewise, the outside of the breech bolt 20a does not contact the inside of the alignment passage 20x. Instead, the barrel seal 20b contacts the inside of the alignment passage 20x. The breech bolt seal 20b reduces friction because it is lubricated. Barrel seal 20b contacts the inside of the alignment passage 20x so that air that flows through the fluid communication channel 20w during firing continues through barrel 20c.

(16) The firing mechanism controls when the breech bolt 20a blocks and unblocks the breech as well as when the piston 20k pneumatically firing the gel round. The firing mechanism operates with timing in five (5) cyclic steps which dictate and drive the movement of the air compression element 20s and the piston 20k. Each step is activated as the trigger is pulled back. First, the air compression element 20s and piston 20k are fully advanced. The breech bolt 20a blocks the breech 20d. Second, the air compression element 20s and piston 20k both retract. The breech bolt 20a no longer blocks the breech 20d so a gel round can enter the pre-firing area 20e. Third, the piston 20k retracts while the air compression element 20s advances. The breech bolt 20a blocks the breech 20d. The gel round is sealed within the alignment passage 20x and any further gel rounds are prevented from entering the pre-firing area 20e. Fourth, the piston 20k quickly advances. The air inside the air compression element 20s suddenly compresses. Due to the pressure difference between the air in the air compression element 20s and the barrel 20c, the gel round is pneumatically propelled out of the barrel. Finally, both the air compression element 20s and piston 20k have fully advanced, hence completing the cycle.

(17) Both the air compression element 20s and the piston 20k retract with the trigger at first. However, the air compression element 20s and piston 20k advance when the trigger has retracted enough. The trigger position for which the air compression element 20s and piston 20k advance are different. This retraction and advancement timing are controlled by two cam follower linkages; one for the air compression element 20s and one for the piston 20k. A breech bolt spring 200 and piston spring 20n attach to the cylinder 20h and the piston 20k respectively. These springs apply a biasing force on the air compression element 20s and piston 20k. Additionally, piston spring alignment 20m ensures piston spring 20n is in line with the piston 20k, air compression element 20s and barrel 20c. Cylinder cam follower linkage 22 and piston cam follower linkage 26 control the positions of the air compression element 20s and piston 20k respectively. The cam follower linkages control when the air compression element 20s and 20k retract and advance. The cam follower linkages are pivoted at the conveyor 18c. The cylinder cam follower linkage 22 is pivoted at the cylinder trigger end 22d. Likewise, the piston cam follower linkage 26 is pivoted at the piston trigger end 26d. The cam follower linkages are also constrained in a vertical plane. As such, when the trigger 18b retracts the cam follower linkages also retract.

(18) The cam follower linkages may engage with the cylinder 20h or piston 20k to retract cylinder 20h or piston 20k. The cylinder cam follower linkage 22 has a cylinder follower coupling 22a which may engage with the cylinder driving coupling 20r. Likewise, the piston cam follower linkage 26 has a piston follower coupling 26a which may engage with the piston driving coupling 20i. When the follower couplings are engaged with their respective driving coupling, the follower couplings may apply a force on their respective driving couplings. If the trigger 18b is retracting while a follower coupling is engaged, air compression element 20s or the piston 20k will also retract. The cam follower linkages also track their respective cam pathway track. The cam pathway track may determine the rotation of the cam follower linkages and whether they are engaged with their driving couplings. The cylinder cam follower linkage 22 has a tracking end 22b which tracks the cylinder cam pathway track 24. Likewise, the piston cam follower linkage 26 has a tracking end 26b which tracts the piston cam pathway track 28. Cylinder biasing spring 22c and piston biasing spring 26c are torsional springs which apply a biasing force on the cylinder cam follower linkage 22 and piston cam follower linkage 26 respectively to raise and lower these follower linkages for their timing actuations. These biasing springs ensure that the tracking ends track their respective pathways. If the cam follower linkages retract enough, the cam pathway tracks cause the cam follower linkages to rotate and have the follower couplings disengage with their driving couplings. If disengagement occurs, only the biasing forces would be present on the air compression element 20s or the piston 20k; the air compression element 20s and piston 20k would quickly advance.

(19) The follower couplings disengage with their driving couplings when the cam follower pathways move the tracking ends low enough. However, the follower couplings engage with their driving couplings when the cam follower pathways allow the tracking to be ends high enough and the follower couplings are in front of the driving couplings. In other words, retracting the cam follower linkages far enough will disengage the follower couplings from the driving couplings, but advancing the cam follower linkages far enough will not engage the follower couplings with the driving couplings until the follower couplings are in front of the driving couplings.

(20) The difference between the air compression element 20s and piston 20k mechanisms is the time at which the follower couplings disengage with the driving couplings. The piston driving coupling 20i becomes unengaged when the trigger 18b retracts farther than where the cylinder driving coupling 20r becomes unengaged. In other words, the piston 20k becomes unengaged, and hence advances, at a later step than the air compression element 20s. The magazine lid 16a, back tray 16b, front tray 16c and the magazine separate 16d are shown more clearly in FIG. 2B.

(21) Figures starting in 3, 4, 5, 6 and 7 show the blaster during steps 1, 2, 3, 4 and 5 respectively. The figures ending in A show a half-plane view of blaster 10 with the cylinder cam follower linkage mechanism highlighted. The figures ending in B only show the cylinder cam follower linkage 22 and the cylinder cam pathway track 24. The figures ending in F show a half-plane view of the blaster 10 with the piston cam follower linkage mechanism highlighted. The figures ending in G ending in only show the piston cam follower linkage 26 and the cylinder cam pathway track 28.

(22) FIGS. 3A and 3F show the blaster 10 in side-elevation sectional views 30, 30 illustrating firing mechanism 20 in an initial trigger at rest first step. Herein the respective cylinder 20h and piston 20k tracking cam pathway tracks 24, 28 are used for raising and lowering operations of cam follower linkages 22, 26 pivotably provided in enlarged and inset views (see, FIGS. 3A, 3B, 3B, 3F, 3G, 3G). FIGS. 3C, 3D, and 3E show first step firing mechanism 20 partial isometric views positioning the cam follower linkages 22, 26 at couplings 22a, 26a driving arms 20i, 20r coupling to cylinder 20h and piston 20k corresponding structures through the cam pathway tracks 24, 28 as functionally attached at the conveyor 18c of the blaster trigger 18.

(23) FIGS. 3A and 3F show the blaster 10 during the first step, where the breech bolt 20a extends into the pre-firing area 20e. There are no gel rounds in the barrel 20c or the pre-firing area 20e. No gel rounds may enter the breech 20d as the breech 20d is blocked by the breech bolt 20a. The trigger 18b is fully advanced. Therefore, the cylinder cam follower linkage 22 and the piston cam follower linkage 26 are also fully advanced. The cylinder trigger end 22d engages with the cylinder driving coupling 20r. Likewise, the piston trigger end 26d engages with the piston driving coupling 20i. FIG. 3C shows an exploded view of the firing mechanism during the first step. FIGS. 3D and 3E show an isometric view of the cam follower linkages, cam pathway tracks, trigger 18b and conveyor 18c during the first step. FIG. 3G shows the piston cam follower linkage 26 tracking with the piston cam pathway track 28. FIG. 3B shows the cylinder cam follower linkage 22 tracking with the cylinder cam pathway track 26, and likewise with FIG. 3B and FIG. 3G. In both figures, the cam follower linkages have not rotated to disengage with their respective driving couplings.

(24) FIGS. 4A and 4F show the blaster 10 in side-elevation sectional views 30, 30 illustrating firing mechanism 20 where initial trigger 18 movement causes the cam follower linkages 22, 26 to start to retract breech bolt 20a and load projectile round 40 while starting to extend piston 20k at the second step. Herein the respective cylinder 20h and piston 20k tracking cam pathway tracks 24, 28 are used for raising and lowering operations of cam follower linkages 22, 26 pivotably provided in enlarged and inset views (see, FIGS. 4A, 4B, 4B, 4F, 4G, 4G). FIGS. 4C, 4D, and 4E show second step firing mechanism 20 partial isometric views positioning the cam follower linkages 22, 26 at couplings 22a, 26a driving arms 20i, 20r coupling to cylinder 20h and piston 20k corresponding structures through the cam pathway tracks 24, 28.

(25) The trigger 18b is pulled back which causes the cam follower linkages to also retract. FIGS. 4G and 4B show the cam follower linkages tracking their respective cam pathway tracks. In both figures, the cam follower linkages have not progressed far enough to rotate and disengage with their respective driving couplings. The retraction of the cam follower linkages causes the follower couplings to apply a force on the driving couplings which in turn causes the air compression element 20s and the piston 20k to retract as well. The breech bolt spring 200 and piston spring 20n become compressed. Due to the retraction of the air compression element 20s, the breech bolt 20a retracts from the pre-firing area 20e. Once the breech bolt 20a is retracted from the pre-firing area 20e, a gel round then enters the pre-firing area 20e through the breech 20d from the front magazine hopper 16c by gravity.

(26) FIGS. 5A and 5F show the blaster 10 in side-elevation sectional views 30, 30 illustrating firing mechanism 20 where further trigger 18 movement allows the cam follower linkages 22, 26 to release and extend breech bolt 20a, and further retract piston 20k at third step. Herein the respective cylinder 20h and piston 20k tracking cam pathway tracks 24, 28 are used for raising and lowering operations of cam follower linkages 22, 26 pivotably provided in enlarged and inset views (see, FIGS. 5A, 5B, 5B, 5F, 5G, 5G). FIGS. 5C, 5D, and 5E show third step firing mechanism 20 partial isometric views positioning the cam follower linkages 22, 26 at couplings 22a, 26a driving arms 20i, 20r coupling to cylinder 20h and piston 20k corresponding structures through the cam pathway tracks 24, 28.

(27) Trigger 18b is pulled back even more which causes the cam follower linkages to also retract further. FIG. 5G shows the tracking between the piston cam follower linkage 26 and piston cam pathway track 28. The tracking end 26b is still high and therefore the piston follower coupling 26a is still engaged with the piston driving coupling 20i. FIG. 5B shows the tracking between the cylinder cam follower linkage 26 and the cylinder cam pathway track 22. The tracking end 22b is now low and therefore the cylinder follower coupling 22a becomes unengaged with the cylinder driving coupling 20r. The retraction of the cam follower linkages causes the piston follower coupling 26a to apply a force on the piston driving coupling 20i which in turn causes the piston 20k to retract further as well. However, the cylinder follower coupling 22a disengages with the cylinder driving coupling 20r. Therefore, the biasing force applied on the air compression element 20s by the breech bolt spring 200 causes the air compression element 20s to advance. The breech bolt 20a extends into the pre-firing area 20e. This extension causes the gel round to become locked in the pre-firing area 20e between the breech bolt seal 20b and the barrel seal 20t. Additionally, this the breech bolt 20b prevents any further gel rounds from entering the pre-firing area 20e through the breech 20d.

(28) FIGS. 6A and 6F show the blaster 10 in side-elevation sectional views 30, 30 illustrating firing mechanism 20 where further trigger 18 advancement releases the cam follower linkages 22, 26 to release piston 20k at fourth step to fire projectile round 40. Herein the respective cylinder 20h and piston 20k tracking cam pathway tracks 24, 28 are used for raising and lowering operations of cam follower linkages 22, 26 pivotably provided in enlarged and inset views (see, FIGS. 6A, 6B, 6B, 6F, 6G, 6G). FIGS. 6C, 6D, and 6E show fourth step firing mechanism 20 partial isometric views positioning the cam follower linkages 22, 26 at couplings 22a, 26a driving arms 20i, 20r coupling to cylinder 20h and piston 20k corresponding structures through the cam pathway tracks 24, 28. Trigger 18b is pulled back even more which causes the cam follower linkages to also retract further. FIG. 6G shows the tracking between the piston cam follower linkage 26 and piston cam pathway track 28. The tracking end 26b is now low and therefore the piston follower coupling 26a becomes unengaged with the piston driving coupling 20i. FIG. 6B shows the tracking between the cylinder cam follower linkage 26 and the cylinder cam pathway track 22. The tracking end 22b is still low and therefore the cylinder follower coupling 22a is still unengaged with the cylinder driving coupling 20r.

(29) The cylinder follower coupling 26a is already disengaged with the piston driving coupling 20i so the air compression element 20s remains in the advanced position. Therefore, the breech bolt 20a continues to seal the breech 20d. However, the piston follower coupling 26a disengages with piston driving coupling 20r. Therefore, the biasing force applied on piston 20k by the piston spring 20n causes the piston 20k to advance. The advance of the piston 20k is sudden causing the air within the air compression element 20s to compress. The compressed air exits the air compression element 20s through the breech bolt channel 20w which launches a gel round through the barrel seal 20t and barrel 20c.

(30) FIGS. 7A and 7F show the blaster 10 in side-elevation sectional views 30, 30 illustrating firing mechanism 20 where returning of trigger 18 with uncoupled cam follower linkages 22, 26 resets firing mechanism 20 to reinitialize at fifth step. Herein the respective cylinder 20h and piston 20k tracking cam pathway tracks 24, 28 are used for raising and lowering operations of cam follower linkages 22, 26 pivotably provided in enlarged and inset views (see, FIGS. 7A, 7B, 7B, 7F, 7G, 7G). FIGS. 7C, 7D, and 7E show fifth step firing mechanism 20 partial isometric views positioning the cam follower linkages 22, 26 at couplings 22a, 26a driving arms 20i, 20r coupling to cylinder 20h and piston 20k corresponding structures through the cam pathway tracks 24, 28. Trigger 18b is now fully advanced. FIG. 7G shows the tracking between the piston cam follower linkage 26 and piston cam pathway track 28. FIG. 7B shows the tracking between the cylinder cam follower 26 and the cylinder cam pathway 22. Both tracking ends are in the high positions and therefore may engage with their respective driving couplings. As such, both cam follower linkages are fully advanced. Both follower couplings become engaged with their respective driving couplings. Additionally, the air compression element 20s and the piston 20k are fully advanced as the cam follower linkages also advanced. If at any step the trigger is returned to being fully advanced, the tracking ends will be high and the follower couplings will be in front of the driving couplings. The figures ending in C, D, E A and F are reprisals of the figures ending in A, F, G and B. Figures ending in C show an exploded view of the firing mechanism during each step. The figures ending in D and E show the cam follower linkages, cam pathway tracks, trigger 18b and conveyor 18c in an isometric view. The figures ending in A and F present enlarged details of the figures ending in A and F respectively. The figures ending in B and G are close copies of the figures ending in B and G respectively.

(31) FIGS. 8A, 8B and 8C show the use of the hopper 16 with two separate areas facilitating reloading by tilting the blaster 10, such that rounds 40 from the magazine front hopper will enter the breech of the blaster firing mechanism 20, through the use of the magazine back tray 16b and magazine front hopper 16c. The two separate areas allow for a sort of reloading which is caused by tilting the blaster 10. Gel rounds 40 may reside in both the magazine back tray 16b and magazine front hopper 16c. However, only gel rounds 40 from the magazine front hopper 16c will enter the breech 20d. If the blaster 10 is fired enough, the front magazine tray 16c will eventually run out of gel rounds 40. FIG. 8A shows that there are few gel rounds 40 in the front magazine hopper 16c. If the blaster 10 is relatively level, gel rounds 40 in the magazine back tray 16b cannot make it over the magazine separator 16d.

(32) FIG. 8B shows blaster 10 being tilted. Tilting the blaster 10 forward will allow gel rounds 40 to go over the magazine separator 16d from the magazine back tray 16b into the magazine front hopper 16c. FIG. 8C shows blaster 10 being returned to a relatively flat tilt, with FIG. 8C shown to have many gel rounds 40 in the front magazine hopper 16c.
