and a gas delivery system


11


. The gas deliver system


110


includes an expansion chamber


13


, a gas transfer line


15


, a gas cylinder connector


17


and a gas cylinder


19


. As can be seen, the gas cylinder


118


is rear mounted and in this configuration tends to interfere with handling, maneuvering, aiming and firing the gun.




Referring now to

FIGS. 2A&B

, a preferred embodiment of a paint ball gun of this invention, generally


200


, is shown to include a barrel assembly


202


, a handle/trigger assembly


240


, and a gas delivery assembly


260


. The barrel assembly


202


includes a barrel


204


and a hollow, paint ball feed tube


206


extending upward from the barrel


204


towards its handle end


208


. The feed tube


206


includes a female connector


210


at its distal end


212


. As shown in

FIG. 2B

, the gun


200


also includes a paint ball dispenser


214


, where the dispenser


214


includes an open top


216


having a lip


218


, a paint ball reservoir


220


, a cover


222


designed to engage the lip


218


so that the top


216


can be closed after the dispenser


214


is filled with paint balls (not shown), and a paint ball dispensing neck


224


depending from a lower central region


226


of the dispenser


214


and having a male connector


228


at this distal end


230


adapted to engage the female connector


210


of the feed tube


206


. The dispenser


214


further includes a slidable paint ball stop


232


shown in its closed state, which is designed to prevent paint balls from entering the neck


224


until the stop is moved using its nob


234


to its open state in a slot


236


. The reservoir


220


of the dispenser


214


is substantially spherical in geometry.




The handle/trigger assembly


240


includes a grip


242


, a trigger guard


244


and a trigger


246


. The handle/trigger assembly


240


also includes a support member


248


having a slot


250


attached to a bottom end


252


of the grip


242


. The gas delivery assembly


260


includes an expansion chamber


262


(an outside


261


of which functions as a secondary grip), a gas cylinder


264


and an elbow shaped gas transfer member


266


interposed therebetween. The transfer member


266


is attached to the gun barrel assembly


202


by bolt


268


which extends from an aperture


270


extending up through the transfer member


266


and engaging the barrel


204


at a position


272


. The transfer member


266


also includes a gas cylinder connector


274


adapted to engage a top


276


of the gas cylinder


264


and a gas transfer conduit


278


adapted to deliver gas in the gas cylinder


264


to the expansion chamber


262


for ultimate use in firing paint balls out of the barrel


204


. Alternately stated, the conduit


278


places the gas cylinder


264


in fluid communication with the expansion chamber


262


, where fluid communication means that gas can flow from the cylinder


264


to the chamber


262


when the top


276


of the cylinder


264


is inserted into the connector


274


. The gas delivery system


260


also includes a brace


280


pivotally mounted in the slot


250


of the support member


248


of the handle/trigger assembly


240


. The brace


280


is mounted in the slot


250


by a bolt


282


passing through an aperture


284


in a brace mount


286


to engage a nut (not shown) on the other side of the brace mount


286


. The brace mount


286


can pivot and slide in the slot


250


so that the brace can be conformed to the angle of the gas cylinder


264


before being tightened into place by the nut. The brace


280


also includes three threaded nobs


288


(two of which are shown) that thread through threaded apertures


290


in a strap portion


292


of the brace


280


. The nobs


288


are designed to engage an outer wall


294


of the gas cylinder


264


at three points


296


(only one of which is shown). The brace


280


and the nobs


288


are designed to secure the gas cylinder


264


in place during use and to decrease stress on the transfer member


266


and the expansion chamber


262


. Without the brace and nobs and because of the forward disposition of the cylinder, the gas cylinder could be subject to considerable impact forces that could result in dislodgment of the gas cylinder, damage to the cylinder, damage to the transfer member, damage to the expansion chamber or any combination of these adverse affects.




Although the brace of

FIGS. 2A-B

is shown to have a rigid strap with nobs designed to engage the gas cylinder at three places, the brace can be a flexible strap with a traditional belt like fastener or the brace can be a flexible strap having a hook and loop fabric fastener as shown in

FIGS. 3A-B

. Of course, any other type of brace can be used as well provided that the brace supports and secures the forward mounted gas cylinder to the gun.

  • 19. The gun of claim 18, further comprising a securing and support member depending from a handle of the gun adapted to secure and support the gas cylinder.
  • 20. A paint ball gun comprising a front mounted, gas delivery system includinga gas cylinder, an expansion chamber extending downward from a front gun position, and a gas cylinder securing and support member including a gas cylinder socket having a connector, where the socket is adapted to surround and protect a majority of the gas cylinder and the connector is adapted to place the gas cylinder into fluid communication with the chamber.
  • 21. The gun of claim 20, wherein the socket extends vertically downward from the chamber.
  • 22. The gun of claim 21, wherein securing and support member further includes a tab depending from a handle of the gun.
