Paintball gun, retrofit kit assembly, and methods of making and using
Paint ball guns frequently break paint balls within the gun. When this happens the gun is jammed with paint and residue of broken paint balls, and a user of the gun cannot fire the gun. An improved paint ball gun includes structures and features which allow quick opening of the barrel and breach of the gun for cleaning. After cleaning of the barrel and breach of the gun, the barrel and gun breach are quickly returned to firing position, and a user of the gun loses only a few seconds of game time before being able to resume firing. A kit of retrofit parts, as well as methods of making and operating the improved paint ball gun are also disclosed.

The invention relates to a pneumatic marker or paint ball gun, to such a paintball gun including a breaking breach feature, to a retrofit kit for converting a conventional paintball gun to embody the improved structure and operation of this invention, and to a methods of making and using such a paint ball gun.
BACKGROUND OF THE INVENTIONPaint ball guns were originally developed for marking objects at a distance. The guns were employed in such fields as forestry and cattle ranching, in which frangible projectiles (generally known as paint balls) were fired against trees to be harvested, or against cattle to be taken to market, for example. When the frangible paint ball hits its target, it breaks open and leaves a brightly colored “paint” mark on the target. For this reason, the paint ball guns themselves are frequently referred to as “markers.” But, more recently paint ball guns are much more widely used in various recreational and game environments, such as simulated war games in which the game players attempt to shoot opposing players with the paint balls, thus marking this opposing player with a particular color of paint from a frangible paint ball. Different colors of paint in the paint balls clearly indicate paint ball hits, and allow players and teams of players to compete against one another.
Paint ball guns using compressed air or gas for power are well known. Until a few years ago most paint ball guns were pneumatically-powered, but mechanically-operated guns. The recent entry into the market of electro-pneumatically operated paint ball guns provided more consistent and better performing guns for the recreational market. An electro-pneumatic paint ball gun provides improved performance with fewer component malfunctions than the earlier mechanical-pneumatic paint ball guns. However, a common problem with all paint ball guns, and especially those modern recreational paint ball guns which have a high cyclic rate of operation (i.e., a high rate of fire) is the breaking of paint balls in the gun breach and barrel. That is, the frangible paint balls inconveniently break in the gun itself, and leave the residue of the frangible shell of the paint ball and the paint contained in this shell, within the operating mechanism of the gun. A paintball gun so fouled is essentially unusable.
As a result, the user of a fouled paintball gun must discontinue operation of the gun, and in order to clear the gun of paint fouling is required to remove the barrel by unthreading it from the receiver of the gun, then swab it out, as well as cleaning the breach of the gun. Then the barrel is re-threaded onto the receiver of the gun. Because unthreading the barrel from the gun exposes the breach chamber of the gun, cleaning out the barrel removes most of the paintball residue and paint from the gun, and allows removal of the remaining paintball residue and paint from the breach mechanism as well. However, when such a partial disassembly and cleaning of a fouled paintball gun is necessary during a game or competition, the player using the gun incurs a great risk of being hit by opponents, and thus of being put out of the game.
SUMMARY OF THE INVENTIONIn view of the deficiencies of the related art, it is an object for this invention to mitigate or eliminate at least one of these deficiencies.
Specifically, it is an object for this invention to provide a paint ball gun having a breach mechanism allowing the gun to quickly break open at the breach so that the barrel and breach can be cleared of fouling.
Another object for this invention is to provide such a retrofit kit allowing a standard paint ball gun with a threadably attached barrel to be modified so that the breach will break open, allowing the barrel to be quickly moved or pivoted aside for removal of fouling.
The present invention addresses the deficiencies of the conventional technology by providing a paint ball gun having a main body including a grip frame, a trigger, and the main body also defining a bore for receiving a paint ball. An elongate barrel secures to the main body and has a breach end receiving the paintball and a muzzle end from which the paint ball is ejected forcefully. A bolt assembly is movable in the main body for opening and closing the breach end of the barrel, and connection structure attaches the barrel to the main body and has a first position aligning and sealingly connecting the barrel with the bore and a second position allowing rapid displacement of the barrel at the breach end from alignment with the bore so that the breach end of the barrel is exposed for cleaning.
A method of using a paint ball gun according to this invention includes the steps of providing a paint ball gun having a main body including a grip frame, a trigger, and defining a bore in the main body for receiving a paint ball. Attaching an elongate barrel to the main body with a breach end receiving the paintball and a muzzle end from which the paint ball is ejected forcefully. Providing a bolt assembly movable in the main body for opening and closing the breach end of the barrel, and connecting structure attaching the barrel to the main body and having a first position aligning and sealingly connecting the barrel with the bore and a second position allowing rapid displacement of the barrel at the breach end from alignment with the bore. Whereby in the second position of the barrel the breach end of the barrel is exposed for cleaning.
A retrofit kit for converting a standard conventional paint ball gun to the advantages of this invention includes a collar member attachable at the location of the paint ball gun barrel by use of a tubular adapter which at an aft end replicates the breach end portion and barrel mounting thread of a paint ball gun barrel. At a forward end portion the tubular adapter member provides a flange portion which has a shoulder bearing on the collar member when tightened. The collar member hingeably carries a hinged portion, and this hinged portion defines a threaded bore for receiving a paint ball gun barrel. In a first position the hinged portion is aligned with the usual position of the paint ball gun barrel, so that the gun is operational normally. In a second position of the hinged portion, the paint ball gun barrel swings aside from its normal position so that the breach is accessible for cleaning.
An advantage of the present invention is that a paint ball gun according to the invention can be quickly cleaned and placed back into operation after breakage of a paint ball in the breach of the gun. That is, the breach end of the barrel and the breach area of the gun itself are accessible when the barrel is moved to its second location.
Additional objects and advantages of the present invention will become apparent to those ordinarily skilled in the pertinent arts upon reading the following detailed description of a particularly preferred embodiment of the invention, which illustrates the best mode contemplated for practicing the invention, taken in conjunction with the accompanying drawings.
