Abstract
A container is adapted to be mounted on a paintball weapon to feed paintballs into the firing chamber of such weapon under the influence of gravity. The container includes a hollow housing in which a monolithic, one-piece helical ramp is located. The paintballs are fed onto the helical ramp and move under the influence of gravity from an inlet section to an outlet section for feeding the paintballs to the weapon. Elements located in the helical path defined by the helical ramp prevent the paintballs from moving backwards.
Claims12
A projectile container comprising:
- A) a hollow housing including
- (1) means for mounting said hollow housing on top of a device which selectively discharges fragile projectiles, such as paintballs, under the influence of a source of fluid pressure,
- (2) a bottom located adjacent to the device when the housing is mounted on top of the device,
- (3) a top unit,
- (4) a side wall connecting said housing bottom to said housing top unit,
- (5) a plurality of viewing ports defined through said housing side wall,
- (6) a loading port unit located on said housing top, and
- (7) a discharge port unit located on said bottom in position to communicate with a firing chamber of the device;
- B) a projectile storage element located inside said hollow housing and including
- (1) an inlet section,
- (2) an outlet section,
- (3) a monolithic, on-piece helical ramp connecting said projectile storage element inlet section to said projectile storage element discharge section, said helical ramp
- (a) defining a continuous helical path extending around a central axis which is vertically oriented when the housing containing said helical ramp is mounted on the device, and
- (b) said helical ramp being sized to slidingly accommodate a multiplicity of projectiles thereon so that said projectiles move from said inlet section towards said outlet section under the influence of gravity,
- (4) a projectile movement control means which controls the movement of projectiles located in sid helical path during projectile movement towards said projectile storage element inlet section for preventing such projectiles from rattling or jamming during such movement, said projectile movement control means including a multiplicity of flexible, arcuate elements extending above said ramp and biased inwardly of said helical path, each flexible element extending in parallel relation to a plane containing a ramp section immediately adjacent to said each arcuate element, each arcuate element being curved to be convex with respect to a direction of projectile movement from said inlet section towards said outlet section.
