DETAILED DESCRIPTION OF THE DRAWINGS

[0016] Although the present invention toy projectile launching system can be embodied in many ways, only one exemplary embodiment of the present is illustrated and described. The exemplary embodiment has been selected in order to set forth one of the best modes contemplated for the invention. The illustrated embodiment, however, is merely exemplary and should not be considered a limitation when interpreting the scope of the appended claims.

[0017] Referring to FIG. 1 in conjunction with FIG. 2 and FIG. 3, a toy projectile launching system 10 is shown. The toy projectile launching system 10 is designed to both internally launch toy ball projectiles 12 and externally launch toy rocket projectiles 13. The toy ball projectiles 12 are made of foam and have a first diameter D1. The toy rocket projectiles 13 are elongated and have a first end 15 and an opposite second end 17. A cylindrical bore opening 19 is formed into the toy rocket projectile 13 from the center of the second end 17. The bore opening 19 has a second diameter D2, which is smaller than the first diameter D1 of the toy ball projectiles 12.

[0018] The toy projectile launching system 10 includes a main tube 14. The main tube 14 has a first end 16 and a constant inner diameter that extends along its length. The inner diameter is slightly larger than the first diameter D1 of the toy ball projectiles 12. The first end 16 of the main tube 14 is open, wherein the first end 16 of the main tube 14 terminates with a launch head 18.

[0019] The launch head 18 defines an exit port 21 through which the toy ball projectiles 12 can be launched. A restriction ring 20 is disposed in the exit port 21. The restriction ring 20 has an inner diameter that is slightly smaller than the first diameter D1 of the toy ball projectile 12. A collar 22 encircles the exit port 21. The collar 22 is internally provided with a mechanical coupling 23, such as threads or the bayonet coupling that is illustrated. Accordingly, in order for any toy ball projectile 12 to pass into or out of the main tube 14, the toy ball projectile 12 must pass through the restriction ring 20 and the collar 22 within the launch head 18.

[0020] A rocket launch adapter 24 is provided. The rocket launch adapter 24 has an elongated launch tube 26 with an outer diameter D3. The outer diameter D3 is the same as, or close to, the diameter D2 of the bore opening 19 in the toy rocket projectile 13. The outer diameter D3 is also smaller than either the inner diameter of the main tube 14 and the inner diameter of the restriction ring 20, Furthermore, when the elongated launch tube 26 is at least as long as the bore opening 19 in the toy rocket projectile 13. The elongated launch tube 26 extends into a base 28. The base 28 has a diameter that fits within the collar 22 of the launch head 18. A flange coupling 30 radially extends from the base 28. The flange coupling 30 is either a threaded connector or a bayonet connector that can selectively engage the mechanical coupling 23 formed into the collar 22. Once the rocket launcher adapter 24 is attached to the launch head 18, the elongated launch tube 26 is concentrically aligned with the main tube 14 and any air exiting the launch head 18 from the main tube 14 is directed through the elongated launch tube 26.

[0021] Referring to FIG. 3, it will be understood that the main tube 14 has a first end 16 and an opposite second end 32. A front pump handle 33 is attached to the main tube 14 a short distance behind the launch head 18. The second end 32 of the main tube 14 terminates with a stop 34. The stop 34 contains one or more small vent holes 36 that enable a small volume of air to pass through the stop 34 at the second end 32 of the main tube 14. A tube seal 38 is also affixed to the stop 34 outside of the main tube 14. The tube seal 38 and the second end 32 of the main tube 14 are received within a wider slide tube 40 in a telescoping manner. The tube seal 38 on the main tube 14 creates an air seal against the interior of the slide tube 40.

[0022] The slide tube 40 has a first end 42 and an opposite second end 44. The first end 42 is open and receives the second end 32 of the main tube 14. The opposite second end 44 of the slide tube 40 is sealed closed by an end cap 48. A second pump handle 46 is affixed to the slide tube 40 near its open first end 42. Accordingly, the second pump handle 46 is affixed to the slide tube 40 near its first end 42 and the end cap 48 is affixed to the slide tube 40 at its second end 44. This creates a slide subassembly 50. The slide subassembly 50 can reciprocally slide along the main tube 14. As the slide subassembly 50 is retracted, air is drawn through the main tube 14 and into the slide tube 40 through vent holes 36 in the stop 34 of the main tube 14. As the slide subassembly 50 is advanced over the main tube 14, the slide subassembly 50 displaces air into the main tube 14 through the vent holes 36, therein increasing the air pressure within the main tube 14. The slide subassembly 50 can be moved relative the main tube 14 by grasping and moving the first pump handle 33 and the second pump handle 46.

[0023] Referring to FIG. 4 in conjunction with FIG. 1 and FIG. 3, it will be understood that to launch toy ball projectiles 12, the rocket launch adapter 24 is not installed. The toy ball projectiles 12 are preferably made of polymeric foam and are compressible. The toy ball projectiles 12 have a diameter D1, but can be forced through the smaller diameter restriction ring 20 at the launch head 18. The toy ball projectiles 12 are manually inserted into the main tube 14 through the launch head 18. To fire the toy ball projectiles 12, the slide subassembly 50 is manually retracted by separating the first pump handle 33 from the second pump handle 46. The slide subassembly 50 is then advanced by moving the first pump handle 33 and the second pump handle 46 toward each other. This movement of the slide subassembly 50 displaces air out of the slide tube 40 and into the second end 32 of the main tube 14. The movement of air directs the toy ball projectiles 12 toward the restriction ring 20 at the first end 16 of the main tube 14. The lead toy ball projectile 12 then wedges in the restriction ring 20, creating a blockage. The air pressure in the main tube 14 increase behind the blockage as the slide subassembly 50 is advanced. The pressure increases until it is sufficient to deform the toy ball projectile 12 and force the toy ball projectile 12 through the restriction ring 20 and into flight. The process can then be repeated until all of the toy ball projectiles 12 are displaced out of the main tube 14.

[0024] Referring to FIG. 5 in conjunction with FIG. 2, it can be seen that to launch a toy rocket projectile 13, the rocket launch adapter 24 is first attached to the launch head 18. The rocket launch adapter 24 has an elongated launch tube 26 that extends the base 28. The base 28 is advanced into the collar 22 of the launch head 18. A flange coupling 30 that radially extends from the base 28 is received by the mechanical coupling 23 formed into the collar 22 and the components are locked with a turn. Once the rocket launch adapter 24 is attached to the launch head 18, the elongated launch tube 26 is concentrically aligned with the main tube 14.

[0025] The elongated launch tube 26 is advanced into the bore opening 19 of the toy rocket projectile 13. Friction retains the toy rocket projectile 13 in place. To fire a toy rocket projectile 13, the slide subassembly 50 is manually retracted and advanced using the first pump handle 33 and the second pump handle 46. This movement displaces air out of the main tube 14 and into the elongated launch tube 26. The toy rocket projectile 13 blocks the elongated launch tube 26. The air pressure in the main tube 14 increases behind the blockage as the slide subassembly 50 is advanced. The pressure increases until it is sufficient to overcome the friction and forces the toy rocket projectile 13 into flight.

[0026] It will be understood that the embodiment of the present invention that is illustrated and described is merely exemplary and that a person skilled in the art can make many variations to that embodiment. For instance, the length, width and shape of the launch assembly can be changed to accommodate different sized projectiles. The shape and appearance of the handles are a matter of design choice. All such embodiments are intended to be included within the scope of the present invention as defined by the claims.
