Definitions

  • the present invention relates to a paintball marker or marker used in the sport of paintball.
  • Paintball is a sporting game having two teams usually trying to capture one another's flag.
  • the players carry compressed gas markers, referred to herein as either “compressed gas markers” or “paintball markers,” that shoot generally spherical paint-filled gelatin sphere projectiles commonly referred to as paintballs.
  • compressed gas markers referred to herein as either “compressed gas markers” or “paintball markers”
  • paintballs that shoot generally spherical paint-filled gelatin sphere projectiles commonly referred to as paintballs.
  • paintballs During play, players advance towards the opposing team's base with the objective of capturing the opposing team's flag, without being hit by a paintball fired from an opposing player's marker. When the paintball hits a player, a "splat" of paint is left on the player and the player is usually eliminated.
  • Compressed gas markers launching mechanisms using compressed gas or air for firing projectiles are well-known.
  • Paintball markers have two basic mechanisms that work in conjunction to fire a paintball from the marker.
  • One of these mechanisms loads a paintball into the breech of a paintball marker, and usually involves a bolt that reciprocates from a loading position that accepts a paintball into the breech, to a firing position.
  • a valving system releases compressed gas from a source of compressed gas to fire the paintball from the marker.
  • Paintball marker action falls into two categories: the “open bolt” action and the “closed bolt” action.
  • a marker body has one or two chambers
  • the upper chamber houses the bolt.
  • the lower chamber houses a hammer and a valve, such as a pin type or poppet valve, also referred to as an exhaust or firing valve.
  • the bolt moves during firing and returns to the loading (open) position after firing, in most cases by "blow back" gas pressure, thus the term "open bolt.”
  • a spring biases the bolt and/or hammer forward.
  • the bolt and hammer are sometimes connected by a mechanical linkage that moves them in concert.
  • the hammer is held in place such as by a sear. Releasing the sear by actuation (pulling) of the trigger allows the hammer and bolt to move forward by spring force.
  • a further valve controls the opening and closing of a flow passage between a high pressure chamber (not required for all open bolts) and the upper chamber and bolt.
  • the bolt in the firing position, is in alignment with the flow passage of the valve. In the firing position, the hammer impacts the valve, releasing high pressure compressed gas through the flow passage and bolt to fire the paintball.
  • the bolt and hammer are arranged to move independently, thereby allowing for less "bounce” or "kick" when the marker is fired, since the bolt is not moving when the valve releases compressed gas.
  • the "closed bolt” action is referred to as such because the bolt remains in the firing position, and paintballs are already chamber, before a mechanism such as a hammer opening the valve.
  • FIG. 1 A cross sectional side view of an illustrative prior art closed bolt mechanically cocking, or "automatically cocking," compressed gas marker 200 is shown in FIG. 1.
  • the closed bolt compressed gas marker 200 has a marker body 202 having an upper chamber or breech 204 and a lower chamber 206.
  • the lower chamber 206 houses firing components, including a cocking rod 208 which projects rearwardly from the marker body, and has a hammer 210 at its forward end.
  • the hammer 210 is biased forward by a cocking spring 212 in the rear of the lower chamber 206.
  • a firing valve 214 in the lower chamber 206 has a stem 216 facing the hammer 210, and a valve seat 218 on the opposite side of the firing valve 214.
  • the firing valve 214 is normally a spring-biased poppet valve, as is known in the art.
  • a high pressure chamber 240 receives compressed gas under pressure from a compressed gas source (not shown) adjacent the seat 218.
  • the source of high pressure compressed gas is a compressed gas tank.
  • the upper chamber 204 houses a bolt 220 having an aperture 222 therethrough.
  • the bolt 220 is attached to a back block 224.
  • Projectiles 226, such as paintballs, are received in the upper chamber 204 via an infeed opening 227.
  • a ram 228 is provided as a means for reciprocating the back block
  • the ram 228 performs as a pneumatically operated piston, and is connected to the back block 224 via a linking rod (not shown but known in the art).
  • a valve 232 generally of the "three-way” variety, positioned at a forward portion of the marker 200, is used to control the supply compressed gas to move the ram 228.
  • a trigger 234 housed in a trigger frame 248 is mechanically linked to the valve 232. Actuating (pulling) the trigger 234 mechanically operates the three-way valve 232, allowing compressed gas to move the ram 228 which in turn moves the linking rod and back block 224 rearward, placing the bolt in a loading position.
  • the cocking rod 208 moves rearward with the back block 224, which catches the rear end of the cocking rod 208 during the back block's rearward movement.
  • the hammer 210 is placed in a "cocked" position, with sear 236 holding hammer 210 in a cocked position.
  • the trigger When the trigger is pulled and the sear 236 is released, it operates the three-way valve 232, which allows compressed gas to contact the rearward portion of the ram 228.
  • the back block 224 moves forward, biasing the bolt 220 to a firing position. Pulling (actuating) the trigger 234 moves the sear 236 away from the hammer 210.
  • the hammer 210 is now released for forward motion and the spring 212 biases the hammer 210 forward to hit the valve stem 216.
  • the firing valve 214 opens to send compressed gas through the bolt 220, and the projectile 226 is fired.
  • the bolt 220 will remain in the firing position (closed bolt) until the next firing operation is initiated by the trigger.
  • a compressed gas marker 10 of the closed bolt "automatically cocking" closed bolt action type is described in detail in U.S. Patent No. 6,763,822. While a mechanically operated paintball marker of the "automatically cocking" closed bolt type is shown, electronic closed bolt markers are available that operate with electronically operated trigger or valving systems.
  • the inventive paintball marker comprises a pressurized gas source; a trigger that opens a trigger pilot valve assembly in communication with the pressurized gas source; a fill valve assembly in communication with the trigger pilot valve and the pressurized gas source; and a firing chamber in communication with the fill valve assembly comprising a bolt that releases pressurized gas to fire a paintball when a pressure in the firing chamber reaches a critical firing pressure.
  • FIG. 1 shows a cross sectional view of a prior art marker.
  • FIGS. 2-7 show sequential cross-sectional views through the paintball marker.
  • FIG. 8 shows another cross-sectional view through the inventive marker.
  • FIGS.9-11 show sequential cross-sectional views of the trigger pilot valve of the paintball marker.
  • FIGS. 12- 14 show sequential cross-sectional views of the fill valve of the paintball marker.
  • Figures show the flow of compressed gas through the marker as shading or dashed lines with arrows.
  • FIGS. 2-8 show a paintball marker 10 having several components common in paintball markers.
  • the marker 10 has a gun body 11 and trigger frame 22, which may be separate but joined pieces, or a single cast piece.
  • the gun body 11 has a breech 16 which chambers paintballs 14 for firing.
  • a projectile infeed tube 18 guides paintballs 14 into the breech 16.
  • the infeed tube 18 may be attached to a projectile hopper or loader (not shown) mounted on top of the marker 10.
  • a barrel 19 of a usable length may be permanently or removably attached to the gun body 11, such as by threaded engagement. This threaded engagement may be preferable for rental situations in which the barrel may be more likely to be damaged.
  • a trigger frame 22 has a grip portion 24 and a trigger guard 26 that protects the trigger 20, and may also house assemblies, such as a power source such as a battery and electronic control circuitry (not shown to add clarity to the drawing) for operation of components of the marker. As shown, however, the frame 22 houses only the trigger pilot valve assembly 30 and fill valve assembly 50.
  • a pressurized gas source not shown engages the marker 10 at opening 12. The compressed gas source supplies compressed gas though the trigger frame 22 to drive the paintball 14 from the barrel 19. As can be seen from the FIGS., the preferred embodiment for this marker 10 uses no traditional regulator to regulate the compressed gas pressure to the marker 10. How the inventive marker eliminates the traditional regulator will now be explained. [0031] The pressurized gas passes from the opening 12 through a passage
  • FIGS. 9-14 show detailed views of each of these assemblies.
  • the trigger pilot valve assembly 30 allows a minimal force in direction A on the trigger 20 to drive valves discussed below that release a relatively high pressure gas (between 400- 1200 PSI) from the pressurized gas source to fire a paintball 14.
  • the trigger pilot valve assembly 30 does this by working in conjunction with the fill valve assembly 50.
  • the marker 10 Before a user pulls the trigger 20, the marker 10 is at rest as shown in FIGS. 2, 9, and 12.
  • a trigger pilot valve chamber 34 and a fill valve chamber 54 fill with pressurized gas from the pressurized gas source.
  • respective poppets 35, 55 seat to block chamber outlets 37, 57.
  • outlets preferably have a lip 37a, 57a surrounding them.
  • the lips 37a, 57a discourage dry ice build-up, since pressurized carbon dioxide is the commonly used pressurized gas.
  • the small lips 37a, 57a have a width of around 0.10 inches, which greatly minimizes the possibility of dry ice building up thereon.
  • the trigger 20 drives the forwardly biased follower 32 rearward as shown in FIGS. 3-6, 10, and 13.
  • the follower 32's pin 32a extends through the seal 32b (preventing compressed gas from venting through vent 82) to drive a poppet pin 35a that extends through the pilot valve outlet 37.
  • the poppet pin 35a unseats the pilot valve poppet 35.
  • the air from the pilot valve chamber 34 travels through the pilot valve outlet 37 through passage 13b to the fill valve assembly 50.
  • the pressurized gas received from the pilot valve assembly 30 drives the larger surface area end 52a of piston 52 to the right.
  • shoulder 52c engages with o-ring 52d, which prevents compressed air (from compressed gas source through passage 56) on the right hand side of the piston 52 from releasing to atmosphere through passage 13e.
  • the gun body 11 comprises a firing chamber 70 in which a bolt 72 slides between a rearwardly spring 73 biased position (FIGS. 2, 3, 4, 7, and 8) and a forward position (FIGS. 5 and 6). Movement of the bolt 72 to the forward position is limited by a shoulder 72a that engages a stop 11a.
  • a spool 74 located within the bolt 72 slides between an adjustable spring 75 biased plunger 90 that moves between its forward position (FIGS.2, 3, 4) and rear position (FIG. 6).
  • a manual or tool operated screw 76 can be moved within the gun body 11 to adjust the bias of the spring 75 and thus also the bias of the spool 74. This adjustment thus controls the speed at which the paintball fires. (See FIG.
  • FIGS. 5 and 6 show the progression of the bolt 72 and spool during the last steps of firing the paintball 14.
  • compressed gas fills the firing chamber 70 and overcomes the bias of bolt spring 73, pushing the bolt forward, preferably when the pressure in the firing chamber reaches about 20 PSI. Movement of the bolt 72 to the forward position allows compressed gas to fill the firing chamber 70 in the area 70a previously occupied by the bolt spring 73.
  • this additional compressed gas builds and drives the spool 74 to the rear of the marker overcoming the plunger 90's forward bias.
  • the follower 32 biases forward closing the flow of compressed gas through the trigger valve pilot assembly 30 to the fill valve assembly 50.
  • the follower 32's forward movement opens a vent passage for compressed gas in the passage 13b and trigger valve pilot assembly 30; this vent passage allows compressed gas to flow through passages 82c, 82b, 82a, and finally vent through vent 82.
  • the speed of paintballs 14 leaving the marker 10 can be adjusted by simply adjusting screw 76, inwards to decrease the chamber volume and increase the pressure in the firing chamber 74 (and thus the velocity of the paintballs fired) or outwards to reduce the pressure and velocity.
  • Other advantages of this marker, particularly in the rental setting are as follows. First, Either or both of the trigger frame 22 and the gun body 11 can be cast formed, which eliminates the more intricate and expensive molding processes required in most markers. For increased durability, the trigger frame 22 and gun body 11 can be of a single piece, eliminating fasteners and connectors normally found in the two piece markers. Second, many, if not all of the assemblies, are removable and replaceable.
  • a replaceable barrel was mentioned above, but other assemblies, such as the bolt, spool, trigger pilot, fill valve, adjustment screw, and trigger could be replaced. This would be preferable to purchasing a new marker, particularly in the rental setting, where replacing markers may decrease profits.
  • the market can be designed without outside plumbing.
