Abstract
A paintball marker (12) has an air powered generator (10) to provide electrical power. A compressed gas conduit (18) is connected to the marker body (12) with compressed gas flowing therethrough. The gas flow is converted to electricity, such as by an impeller (52) that is mounted to a first end of a rotating shaft (48) with a magnet (50) mounted to a second end of a rotating shaft (48) with a coil (45) positioned proximal to the magnet (50) to create electricity upon rotation of the shaft (48) due to flow of compressed gas past the impeller (52). The created electricity can be used to power electrically powered components on board the marker (12) or recharge batteries (24) therein.
Description
- This application claims priority to earlier filed U.S. Provisional Application Ser. No. 60/545,397, filed Feb. 17, 2004, the contents of which are incorporated herein by reference.
- 1. Field of the Invention
- The present invention generally relates to paintball markers. More specifically, the present invention relates to providing electrical power for a paintball marker
- 2. Description of the Related Art
- Current paintball markers are typically powered by pneumatics where compressed air is used to operate various components of the marker. For example, compressed air is commonly used to control paintball loading by actuating a piston back and forth which is connected to a bolt assembly. Also, paintball launching is also carried out by blowing compressed air behind the paintball. In sum, compressed air is a readily available resource in current paintball markers.
- Current paintball markers also use electronics for operation control. For example, many markers include an operating system that controls the operation of the markers, such as firing rate. Triggering can also be electronic in nature. A typical marker includes a 9 volt battery (e.g. rechargeable) for providing the necessary electrical power. Also, add-on components, such as hoppers, operate on electricity and, therefore, need a source of electricity.
- As paintball markers become more complicated, they become more reliant on electronics while placing a larger load on the existing battery supply resulting in more frequent recharging and replacement of the battery. As can be understood, this is particularly problematic during game play.
- In view of the foregoing, there is a need to provide an improved electrical source to supply power to a marker for effective operation thereof. There is a need to be able to recharge the onboard battery “on-the-fly” during game play so as to not interrupt paintball marker operation. There is a further need to supplement the electrical power in a paintball marker.
- The present invention solves the need for recharging a battery and prolonging the battery life of a paintball marker by providing a pneumatic dynamo to harness the compressed air source of the paintball marker and convert it to electricity for use therein.
- A paintball marker built according to the teachings of the present invention has an electrical circuit for controlling one or more operations or features of the paintball marker, a compressed air source for powering one or more operations or features of the paintball marker, and an air powered generator placed inline with the compressed air source to generate electricity to power the electrical circuit and any other electrical needs of the paintball marker.
- In view of the foregoing, an object of the present invention is to provide a pneumatic dynamo for converting readily available air flow to electricity for use by the paintball marker.
- A further object is to provide a pneumatic dynamo that can recharge a battery or batteries used in a paintball marker.
- Another object of the present invention is to provide s supplemental source of electricity to be used by electrically operated components within a paintball marker.
- Yet another object of the present invention is to provide an inexpensive and compact pneumatic dynamo.
- These and other features, aspects, and advantages of the present invention will become better understood with reference to the following description, appended claims, and accompanying drawings where:
-
FIG. 1 is a partial side view of a paintball marker using the preferred embodiment of the present invention; -
FIG. 2 is a cross-sectional view of the preferred embodiment of the present invention; -
FIG. 3 is a top cross-sectional view of an alternative embodiment of the present invention; -
FIG. 4 is a partial side cross-sectional view of the alternative embodiment ofFIG. 3 ; and -
FIG. 5 is a side cross-sectional view of the alternative embodiment ofFIG. 3 . - Referring now to
FIG. 1 , the preferred embodiment of the pneumatic dynamo of the present invention is shown at 10 integrated within apaintball marker 12.Paintball markers 12 are generally powered by compressed gas contained in acylinder 14 and also typically have ahopper 13 for storage ofpaintball projectiles 15. Apressure regulator 16 is attached to thecylinder 14 to regulate the flow of compressed gas from thecylinder 14 and into ahose 18. The other end of thehose 18 is attached to thepneumatic dynamo 10. Thepneumatic dynamo 10 is attached to asecondary pressure regulator 20. Compressed gas flows from thecylinder 14, through thepressure regulator 16, through thehose 18, into thepneumatic dynamo 10, into thesecondary pressure regulator 20 viafluid passage 32 and into thepaintball marker 12 to power the operations of thepaintball marker 12 such as loading and firing paintballs. Such pneumatic operations of various components of apaintball marker 12 are very well known in the art and need not be discussed in detail herein. - While the compressed gas is flowing through the
pneumatic dynamo 10, the compressed gas is harnessed to generate electricity. The present invention contemplates any type of structure or device that can convert air flow to electricity where that electricity is available to thepaintball marker 12 for any of its electrical needs. This electricity is transferred through a firstelectrical wire 22 and, preferably, into arechargeable battery 24, but it could be directly fed into anelectrical circuit 26.Electrical wire 22 is shown as a pair of double lines to represent any type of electrical interconnection, which may include a single wire or more than two wires. Such electrical connection depends on the electrical design of thepaintball marker 12. The battery supplies power to anelectrical circuit 26 by means of a second electrical wire 28 (also represented as a pair of double lines). Theelectrical circuit 26 contains the logic necessary to electrically control any number of operations and features of thepaintball marker 10. For example, somepaintball markers 12 havehoppers 13 that have powered sorters to prevent jamming of thepaintball projectiles 15. These types of poweredhoppers 13, or other powered accessories, receive electrical power and control signals from theelectrical circuit 26 of thepaintball marker 12 through a third electrical wire 27 (represented as a pair of dashed lines). - Referring now to
FIG. 2 , a cross-sectional view of the preferred embodiment of thepneumatic dynamo 10 of the present invention is shown generally at 10. The pneumatic dynamo has abody 30. Within thebody 30 is afluid passage 32 having afluid inlet 34 and afluid outlet 36. The fluid inlet is connected to thehose 18 and the fluid outlet is connected to thesecondary pressure regulator 20 of thepaintball marker 12. Thepneumatic dynamo 10 is thus positioned inline with the gas supply to thepaintball marker 12 viasupply cylinder 14. While it is preferred that thepneumatic dynamo 10 is located as shown inFIG. 1 , if can be placed anywhere on or within thepaintball marker 12 that has air flow. - Adjacent to the
fluid passage 32 is agenerator 40. Thegenerator 40 has astator 42 and arotor 44. The stator has acoil 45 which is mounted adjacent to and about therotor 44. The stator also has a pair ofelectrical leads 47 which are connected to thecoil 45 and to anelectrical connector 46. Theelectrical connector 46 is connected to theelectrical wires 22 of thepaintball marker 12. Therotor 44 includes ashaft 48, amagnet 50, and animpeller 52. Preferably, thecoil 45 completely encircles therotor 44 andmagnet 50 therein, but other configurations are possible that are well known in the art. - The
shaft 48 of therotor 44 is rotatably mounted within thebody 30 of thepneumatic dynamo 10. Themagnet 50 is attached to one end of theshaft 48 and adjacent to thestator 42. Themagnet 50 is, therefore, rotatably mounted within thegenerator 40 with thecoil 45 positioned thereabout. Theimpeller 52 is attached to the opposite end of theshaft 48 and has a number of blades (or foils) 54. At least a portion of theblades 54, such as the free endsportions 54 a, of theimpeller 52, are interposed influid passage 32 such that the flow of the compressed gas through thefluid passage 32 pushes theblades 54 causing theimpeller 52 to turn. Theimpeller 52 turning causes theshaft 48 to turn themagnet 50, which induces electricity in thestator 42. It is well known that rotation of a magnet relative to a coil winding creates an inductive effect to thereby create current flow through the coil. The size and configuration of theimpeller 52,magnet 50 and thecoil 45 can be modified to suit the desired electrical output. For example, the output can be designed to output a 9 volt supply, which is typically compatible with most paintball markers. - In an alternative embodiment shown in
FIGS. 3 through 5 , theshaft 48 of therotor 44 is completely disposed within thefluid passage 32. Also thecoil 45 is wound about an iron ring 49 positioned adjacent to themagnet 50 of therotor 44. Thecoil 45 in this embodiment is also wound into two separate windings disposed opposite each other on the iron ring 49. As described earlier, many variations in the components are well known in the art for creating electrical induction in a wire by means of rotating a magnet relative to a coil. Alternatively, thecoil 45 may be mounted to theshaft 48 with themagnet 50 positioned adjacent thereto. As theshaft 48 rotates, thecoil 45 is rotated adjacent to the magnet inducing electricity in thecoil 45. - Although the
pneumatic dynamo 10 of the present invention has been described as a separate component that may be connected or disconnected to thepaintball marker 12 as desired, the present invention may easily be integrated into the overall structure of thepaintball marker 12 as a permanent component. As stated above, it may be positioned anywhere in thepaintball marker 12 where there is gas flow or even in a separate pneumatic flow circuit. The present invention is shown to use an impeller structure 5 to rotate ashaft 48. However, other structures may be employed, such as a plunger with linear or reciprocating movement. In general, movement of a magnet relative to a coil is carried out to generate the required electricity. For example, the magnet may be stationary while the coil is moved. Moreover, an electrical circuit may also be provided for conditioning the electrical signal that has been induced. - Further, an LED or LCD display may be provided to monitor the operation of the
pneumatic dynamo 10 and thepaintball marker 12. Optional control elements that interface with thepaintball marker 12 and/orpneumatic dynamo 10 may include buttons or levers to modify settings within themarker 10 or an interface means so that themarker 10 can be monitored by a remote device. Finally, the interface means may be through a wired connection or other wireless means that allow both monitoring and control of themarker 10 as well as allowing control programs to be downloaded into themarker 10 as desired. - While there is shown and described herein certain specific structure embodying the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
