Multiple cannister supply paintball marker
A paintball marker using a gas combination chamber having multiple inputs for sealably connecting to multiple gas supply canisters. Multiple seals and piercing needles are provided to release the compressed gas from the separate canisters into the combination chamber. A single release valve is then provided for launching the paintball marker using the combined gas supply. A body including an alignment chamber and a screw on back cover is provided for aligning the canisters in position and then generating the pressure for sealing and piercing the multiple canisters. The multiple canister connection provides an increased gas capacity over known markers while still using the low supply capacity of the commercially available gas canisters. The simple guided alignment provided by the marker body and the screw on pressure cap provide for quick field replacement of the canisters in the rough playing environment associated with the game of paintball.

BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to the field of paintball markers. In particular, the present invention relates specifically to paintball markers using gas provided by a gas canister. Known art may be found in U.S. Class 124 Mechanical Guns and Projectors: Subclass 53 Having Cut-Off, Subclass 63 Provided by Movement of User-Actuated, Projector-Mounted Pressure Member, Subclass 73 By Valve Means; Class 141 Fluent Material Handling, with Receiver or Receiver Coacting Means: Subclass 290 With Flue or Vent Externally Returning to Supply as well as in other classes and subclasses.
2. Description of the Known Art
As will be appreciated by those skilled in the art, gas cartridges have been used to supply gas to paintball markers. Patents and Applications disclosing information regarding various canister or marker configurations include U.S. Patent Publication No. 2003/0131834, issued to Rice on Jul. 17, 2003; U.S. Patent Publication No. 2003/0178018, issued to Cherry on Sep. 25, 2003; U.S. Patent Publication No. 2004/0144012, issued to Adams on Jul. 29, 2004; U.S. Pat. No. 1,743,576, issued to Smith on Jul. 14, 1927; U.S. Pat. No. 3,494,344, issued to Vadas on Feb. 10, 1970; U.S. Pat. No. 4,362,145, issued to Stelcher on Dec. 7, 1982; U.S. Pat. No. 4,819,609, issued to Tippmann on Apr. 11, 1989; U.S. Pat. No. 5,634,456, issued to Perrone on Jun. 3, 1997; U.S. Pat. No. 5,839,422, issued to Ferris on Nov. 24, 1998; and U.S. Pat. No. 6,494,194, issued to Shipachev on Dec. 17, 2002. Each of these patents and publications are hereby expressly incorporated by reference in their entirety.
This prior art shows the desire to use a gas cartridge because a filled cartridge may be shipped within the department of transportation guidelines. However, the prior art fails to teach the limitations imposed by these cartridges and how to overcome these limitations. Thus, it may be seen that these prior art patents are very limited in their teaching and utilization, and an improved marker is needed to overcome these limitations.
SUMMARY OF THE INVENTIONThe present invention is directed to an improved paintball marker having an increased gas supply through a sealing and piercing connection with multiple gas canisters. In accordance with one exemplary embodiment of the present invention, a paintball marker is provided using a pressurized gas supplied from a plurality of gas cartridges. Each of the gas cartridges has a gas containment body that needs to be pierced to release the pressurized gas. The inventive aspect of the marker uses a plurality of gas inputs to connect to multiple gas cartridges. The marker uses a unique construction such that each of the multiple gas inputs is sealably connectable to one gas cartridge and then a piercing needle is used to puncture the sealed gas cartridge. The gas is then directed by the needle and the input to a common chamber. In this manner, the gas inputs are fluidly connected to a gas combination chamber. This combined gas flow is then used to launch paintballs. As noted by this invention, one inventive aspect of the invention is provided by a pressure application device which applies the sealing pressure to the gas cartridges and then applies the piercing pressure to the gas cartridges.
A method is also taught that uses the elements of providing multiple inputs for accepting the pressurized gas from each of gas cartridges; releasing the pressurized gas from the cartridges; combining at least a portion of the pressurized gas from each of the gas cartridges to form a combined gas supply; and selectively releasing the combined gas supply to act on the paintball. Other elements that may be included in this method include sealing at least a portion of the multiple gas cartridges and then piercing the sealed portion of a plurality of the multiple gas cartridges to release the pressurized gas; providing a piercing needle and pressing the gas cartridge against the piercing needle; or providing a gas expansion chamber and using a combined volume chamber to provide a launching volume of gas.
One object of the present invention is to provide an increased gas supply by combining multiple cartridge supplies while still providing a single valve assembly that is easily and inexpensively controlled.
A further object of the invention is a method for sealing and piercing multiple cartridges without prematurely releasing gas from one of the canisters.
These and other objects and advantages of the present invention, along with features of novelty appurtenant thereto, will appear or become apparent by reviewing the following detailed description of the invention.
BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGSIn the following drawings, which form a part of the specification and which are to be construed in conjunction therewith, and in which like reference numerals have been employed throughout wherever possible to indicate like parts in the various views:
As shown in
The launching device 126 includes a hammer compression spring 128 mounted between a hammer assembly 130 and a bolt assembly 132. In the basic operation of the marker 100, the extension 123 of the cocking pump handle 122 engages the bolt assembly 132 and is pushed back until the hammer release 131 engages the bolt assembly 132. This rearward movement of the bolt assembly 132 also allows a paintball (not shown in this Figure) to drop from the hopper into the breech area. The coking pump handle 122 is then moved forward which moves the paintball 10 into the firing position and carries the compressed spring 128 and hammer assembly 130 forward with the cocking pump handle 122. The firing position of the paintball is shown in
As shown in
A releasable chamber seal 154 is formed in one end of the chamber 144 that allows for selectively releasing the combined gas supply 158. This chamber seal 154 is formed as a pressure release valve 146 that is mounted to the hammer end of the gas combination chamber 144. The pressure release valve 146 has a valve seal 148 that is biased into a sealed position by the seal biasing spring 150. In this manner, the hammer may impact the seal driving rod 149 to move the valve seal backwards to a released position 151 to release the combined pressurized gas supply 158. The seal biasing spring 150 then returns the valve seal 148 to the sealed position.
An important aspect of the present embodiment is the alignment and pressure sealing of all of the canisters 20 into one of the inputs 136 before piercing of any of the canisters 20. As shown in
