Pneumatic paintball marker
First Claim
1. A pneumatic paintball marker, comprising in combination:
- a housing including an hollow open ended firing chamber having a first open end operatively coupled to a barrel and a second open end closed by a removable back plug;
said firing chamber having a paintball-loading hole in a side wall thereof at a location between said back plug and said barrel;
a door surmounting said firing chamber and slidingly coupled to said housing for providing access to said paintball-loading hole when the door is pivoted to an open position and for sealing said firing chamber when said door is pivoted to a closed position;
a means for camming, said means for camming operatively coupled to said door;
a means for controlling door position, including a linear actuator operatively coupled to said means for camming such that said cam means transforms a linear motion of said linear actuator into a sliding motion of said door for sliding said door from the open to closed position and from the closed to open position;
a pin valve interposed between a source of compressed gas and a bore leading to said firing chamber and located behind said linear actuator for controlling a gas path between said source of compressed gas and said firing chamber;
a selectively openable gas path between said source of compressed gas and said linear actuator of said means for controlling door position, anda trigger operatively coupled to said means for controlling door position, said trigger adapted to open the selectively openable gas path between said source of compressed gas and said linear actuator for moving said linear actuator from a forward to a backward position such that said means for camming transforms linear motion of said linear actuator into sliding motion of said door for sliding said door from the open position such that a paintball is loaded into the firing chamber to a closed position for sealing the firing chamber and then continuing to move said linear actuator backward to a position of impact with said pin valve for opening the gas path between said source of compressed gas and said firing chamber for firing the paintball through and out said barrel in an opposite direction of movement of said linear actuator when said trigger is actuated.

Abstract
Paintball marker including a firing chamber having a barrel coupled to one end and a removable back plug coupled to an opposing end, a door surmounting a chamber loading hole disposed between back plug and barrel; a cam coupled to door; an actuator coupled to door cam; a pin valve interposed in a first gas path between a gas source and a passage leading to the chamber, and a trigger coupled to a second gas path between the gas source and actuator for opening the second gas path for actuating the actuator such that the door cam transforms motion of the actuator into pivoting motion of the door from an open position such that a paintball is loaded into the chamber to a closed position and then continuing to actuate the actuator to coact with the pin valve for opening the first gas path for firing the paintball.

13. A pneumatic paintball marker, comprising in combination:
-
a housing including an hollow open ended firing chamber extending therethrough and comprised of a first open end, a second open end, and a paintball loading hole disposed in a sidewall thereof at a location between said first open end and said second open end of said firing chamber; a barrel comprised of an entrance end and an exit end and shaped for receiving and passing a paintball therethrough, said entrance end being operatively coupled to said first open end of said firing chamber; a removable back plug operatively coupled to said second open end of said firing chamber opposite said first open end for sealing said second open end of said firing chamber during use, said removable back plug removed from said second open end of said firing chamber for allowing cleaning access through said barrel and firing chamber; a door surmounting said firing chamber and pivotally coupled to said housing for providing access to said paintball-loading hole when the door is pivoted to an open position and sealing said firing chamber when said door is pivoted to a closed position; a means for camming operatively coupled to said door; a means for controlling position of said door including a linear actuator operatively coupled to said means for camming such that said cam means transforms a linear motion of said linear actuator into a rotational motion of said door for pivoting said door from the opened to closed position and from the closed to opened position under direction of said means for controlling position of said door; a valve operatively coupled to said means for controlling position of said door and interposed between a source of compressed gas and a bore leading to said firing chamber for controlling a gas path therebetween under the control of said means for controlling position of said door; a trigger operatively coupled to said means for controlling position of said door wherein when said trigger is actuated said means for controlling position of said door pivots said door from the open position such that a paintball is loaded into the firing chamber to a closed position for sealing the firing chamber and then subsequently opens said valve for opening the gas path between said source of compressed gas and said firing chamber for firing the paintball through and out said barrel of said pneumatic paintball marker. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A pneumatic paintball marker, comprising in combination:
-
a housing including an hollow open ended firing chamber extending therethrough and comprised of a first open end, a second open end, and a paintball loading hole disposed in a sidewall thereof; a barrel operatively coupled to said first open end; a removable back plug operatively coupled to said second open end, a door pivotally coupled to said housing and surmounting said firing chamber loading hole disposed in said sidewall between said back plug and said barrel; a door cam operatively coupled to said door; an actuator coupled to said door cam; a valve operatively coupled to said actuator and interposed in a first gas path between a source of compressed gas and a passage leading to said firing chamber, and a trigger operatively coupled to a second gas path between the source of compressed gas and said actuator, said trigger adapted to open said second gas path to move said actuator, said door cam adapted to transform motion of said actuator into pivoting motion of said door from an open position in which a paintball is loaded into said firing chamber to a closed position and then continues to move said actuator to coact with said valve for opening said first gas path for firing the paintball. - View Dependent Claims (22, 23)
