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;

said second portion including a trigger operable to discharge said air pump;

at least one launching tube adapted to carry a projectile in readiness for launch and 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 such that 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; and

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

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

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

3. The projectile launcher of claim 2 wherein:

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

said first portion false barrel structure is movably carried about the exterior of said second portion false barrel structure for motion between said first position and said second position.

4. The projectile launcher of claim 1 wherein:

the at least one launching tube is movable relative to said breech; and

said movabilty of said at least one launching tube is adapted to facilitate said passage of projectiles.

5. The projectile launcher of claim 4 including:

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

advancement apparatus adapted to facilitate selection of a projectile to be launched, said selection being automatically performed during said operational cycle of said launcher.

6. The projectile launcher of claim 5 wherein:

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

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

7. The projectile launcher of claim 5 wherein:

said holding apparatus comprises a chamber that holds a plurality of projectiles and said advancement apparatus facilitates engagement of a selected projectile with the at least one launching tube; and

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