Projectile launchers

1. An air operated projectile launcher comprising:

a first portion adapted for reciprocating travel between a first position and a second position relative to a second portion, said travel including at least a linear component, movement from said first position to said second position relatively moving an extremity of said first portion toward said second portion;

the second portion including all members of the launcher that the first portion extremity moves relative to when traveling from the first position to the second position with respect to the linear component of travel;

an air pump having a cocked state and a discharged state, said air pump biased toward said discharged state;

a trigger operable to discharge said air pump;

said trigger and said second portion adapted to facilitate the use of a single hand to simultaneously actuate the trigger and hold the launcher by the second portion;

at least one launching tube adapted to carry a projectile proximate a muzzle of said launching tube, in readiness for launch;

said launching tube adapted to receive air discharged from said air pump to effect launch of such a projectile;

operative travel of said first portion from said first position to said second position effecting actuation of at least one task selected from the group consisting of cocking said air pump and selecting a projectile to be launched;

said launcher adapted to facilitate operation whereby a user holding said second portion may press said first portion against a planar surface to relatively move said first portion from said first position to said second position without any member of said second portion extending beyond the plane of said planar surface;

said first portion being automatically returned from said second position to said first position during an operational cycle of said launcher;

projectile holding apparatus adapted to carry a plurality of projectiles available for launch via discharge of said pump; and

advancement apparatus adapted to facilitate selection of a projectile to be launched.

2. The projectile launcher of claim 1 wherein said first portion extremity includes a contact surface adapted to facilitate operational engagement with and distribution of force over a relatively broad surface area of an engaged object.

3. The projectile launcher of claim 1 wherein:

said holding apparatus comprises a plurality of said projectile launching tubes; and

said air pump is cocked by travel of said first portion from said first position to said second position.

4. The projectile launcher of claim 3 wherein:

said launching tubes are part of a movably carried projectile magazine;

said selection of a projectile to be launched is automatically performed during said operational cycle of said launcher; and

said advancement apparatus moves the launching tube of a selected projectile into firing alignment.

5. The projectile launcher of claim 4 wherein said first portion extremity includes a contact surface adapted to facilitate operational engagement with and distribution of force over a relatively broad surface area of an engaged object.

6. The projectile launcher of claim 3 wherein:

said launching tubes are fixed in position on said first portion or said second portion of said launcher;

said selection of a projectile to be launched is automatically performed during said operational cycle of said launcher; and

said advancement apparatus provides fluid connection of air discharged by said air pump to the launching tube of a selected projectile.

7. The projectile launcher of claim 6 wherein said first portion extremity includes a contact surface adapted to facilitate operational engagement with and distribution of force over a relatively broad surface area of an engaged object.

8. The projectile launcher of claim 1 wherein:

said holding apparatus comprises a chamber that holds a plurality of projectiles;

said air pump is cocked by travel of said first portion from said first position to said second position;

said selection of a projectile to be launched is automatically performed during said operational cycle of said launcher; and

said advancement apparatus facilitates engagement of a selected projectile with said launching tube.

9. The projectile launcher of claim 8 wherein said first portion extremity includes a contact surface adapted to facilitate operational engagement with and distribution of force over a relatively broad surface area of an engaged object.

10. The projectile launcher of claim 1 wherein said second portion includes an air passage providing fluid connection of pressurized air between said air pump and said launching tube of a selected projectile.

11. The projectile launcher of claim 1 wherein said trigger is part of said second portion.

12. The projectile launcher of claim 1 including:

a breech adapted to allow passage of projectiles into firing alignment;

the muzzle of a said launching tube being positioned within said breech during at least part of an operational cycle of said launcher.

13. The projectile launcher of claim 2 wherein said extremity includes an irregular contact surface for said engagement.

14. The projectile launcher of claim 2 wherein said extremity includes a generally broad contact surface for said engagement.

15. The projectile launcher of claim 2 wherein said extremity includes a resilient contact surface for said engagement.

16. The projectile launcher of claim 1 wherein said first portion includes a false barrel structure through which said projectiles pass when launched.

17. The projectile launcher of claim 16 wherein:

said second portion includes a false barrel structure that is part of the structure through which said projectiles pass when launched; and

said first portion false barrel structure is movably carried in or on said second portion false barrel structure for motion between said first position and said second position.

18. The projectile launcher of claim 16 wherein the muzzle of said false barrel structure is adapted to receive external force to move said first portion from said first position to said second position.

19. The projectile launcher of claim 1 wherein:

said first portion includes a member formed as a handle at a position forward of said trigger;

said handle being offset from or non-concentrically aligned with respect to an axis of projectile discharge.

20. The projectile launcher of claim 2 wherein said extremity of said first portion is offset from or non-concentrically aligned with respect to an axis of projectile discharge.
