Problems solved by technology

However, a common problem with the conventional electro-pneumatic paint ball guns is that they use a mechanical sear device to release a hammer.
The adjustment of the engagement and release of the mechanical hammer and sear remains an uncertain element of conventional paint ball gun operation, requiring frequent adjustments in order to operate at high cyclic rates.
As can be understood from this explanation, the successful operation of such an open bolt paint ball gun involves a considerable timing challenge in order to achieve high cyclic rates (i.e., high rates of paint ball fire).

first embodiment

[0031] Referring to the drawing Figures in conjunction with one another, and first considering especially FIG. 1, paint ball gun 10 includes a main body 12, with a grip frame 14 pivotally carrying a trigger 16 and defining a trigger guard 18. A barrel 20 is attached to the main body 12, and defines a breech opening 22a by which a paint ball is received along a feed tube 28, and muzzle opening 22b by which a paint ball is discharged. A gas inlet regulator body 24 is also attached to the main body 12, and provides communication via an inlet 24a (arrowed on FIG. 1) with a source of high pressure gas (not shown in the drawing Figures) for powering the paint ball gun 10.

[0032] A paint ball hopper and feeding device (also not seen in the drawing Figures) can be mounted on the top of the main body 12, feeding paintballs 26 into the gun 10 (i.e., into breech opening 22a) via an upper extent of feed tube 28 defining a feed port 30. The feed port 30 opens into a top one 32 of two substantiall...

third embodiment

[0061] In this third embodiment, forward movement of the hammer member 258 and bolt 236 compresses spring 200. After the hammer member 258 bumps open the poppet valve member 248 discharging the paint ball 226, the spring 200 drives the hammer member 258 and bolt 236 back to the positions seen in FIG. 5, preparing the gun 210 for another firing action.

[0062] Turning to FIGS. 13-15, yet another embodiment (fourth embodiment) of a paint ball gun according to the present invention is illustrated. In order to obtain reference numerals for us in describing this fourth embodiment to paint ball gun, features which are the same as or analogous to those of the first embodiment are referenced on FIGS. 13-15 using the same numeral employed above, and increased by three-hundred (300). As is noted with respect to some elements of the fourth embodiment, component parts differ from the preceding embodiments and these differences are explained below.

[0063] Considering now FIG. 13, a double-solenoid...

fourth embodiment

[0069] Thus, as FIG. 13 shows, pressurized gas at the first regulated gas pressure will flow from chamber 334c along passages 352, 354, and 336a and to chamber 338, discharging the paint ball 326 along barrel 320 as is further explained below. Note that FIG. 13 shows just the initial movement of paint ball 326 into the chamber 338 of the barrel 320. That is, it will be seen that in this fourth embodiment also, forward movement of the hammer member 358 and bolt 336 compresses spring 300. After the hammer member 358 bumps open the poppet valve member 348 discharging the paint ball 326, the spring 300 drives the hammer member 358 and bolt 336 back to the starting positions, not seen in the drawing Figures, but refer to FIG. 9 for illustration of the analogous positions.

[0070]FIG. 14 shows the paint ball gun with paint ball 326 being discharged from the barrel 320, while FIG. 15 shows the bolt 336 being moved back toward its open position by action of hammer assembly 358. It is to be no...

Abstract

An electro-pneumatically operated paint ball gun operates without the use of a mechanical sear, and includes a pneumatically-operated hammer assembly effective to bump open a discharge valve and fire the gun. A hammer member of the hammer assembly is preferably coupled for reciprocation in unison with a bolt of the paint ball gun. A method of operating the inventive paint ball gun includes pneumatic reciprocation of the hammer member and bolt in unison. The paint ball gun may include a pair of solenoid valves activated alternatingly to flow pressurized gas to the hammer assembly, and to allow an increased cyclic rate of operation for the paint ball gun.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is a Continuation-in-Part of U.S. application Ser. No. 10 / 965,599, filed 14 Oct. 2004, which is a Continuation of U.S. application Ser. No. 10 / 452,670, filed 30 May 2003, now U.S. Pat. No. 6,889,682, issued 10 May 2005, and the disclosure of which is hereby incorporated by reference to the extent necessary for a full enabling disclosure of this present invention.FIELD OF THE INVENTION [0002] The invention relates to a pneumatic marker or paint ball gun, and to a method of operating such a paint ball gun. BACKGROUND OF THE INVENTION [0003] Paint ball guns were originally developed for marking uses such as forestry and cattle ranching, in which frangible projectiles or paint balls were fired against trees to be harvested or cattle to be taken to market, for example. 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 vario...
