Electronic Paintball Marker
The present invention is directed to an electronically controlled paintball marker with magnetic control, having a trigger in communication with an electronic controller and a bolt configured to reciprocate in response to a magnetic force applied to a portion of the bolt during a firing sequence. Actuation of the trigger initiates a firing sequence activating electromagnets controlled by the electronic controller.
The present invention is directed to an electronically controlled paintball marker. In particular, it relates to a magnetic paintball firing control system.
BACKGROUNDIn recent years, the popularity of the combat game known as “Paintball” has increased dramatically. In one form of this game, players on two teams are each supplied with a paintball marker and a number of paintballs, that is, rounds of ammunition. The paintballs usually comprise a spherical gelatin or similar shell filled with a non-toxic, water-soluble, biodegradable paint. Paintball markers fire these paintballs using compressed gas as a propellant. These gas-propelled balls strike players and rupture, and in so doing, “paint” the target player and provide dramatic evidence of the hit, without substantially injuring the player.
A typical firing cycle of a paintball marker begins by a user manually cocking a bolt in the breech of the marker rearwardly, creating an opening through which a paintball from a loader in communication with the marker is able to fall, under the force of gravity, into the breech. Once the paintball is in the breech, the bolt slides forward to contact the paintball. When the trigger is pulled, a valve is momentarily opened releasing compressed gas through the bolt into the breech, forcing the paintball out of the barrel of the marker.
Semi-automatic paintball markers operate typically operate using a “blow-back” method wherein a first source of compressed gas discharges the paintball and a second source of compressed gas operates to return the firing mechanism to a ready-to-fire position. Such devices, however, require considerable compressed gas to fire and recoil the mechanism of the gun. An example of such a marker is shown in U.S. Publication No. 2004/0144377 to Dobbins, herein incorporated by reference, and shows a bolt that reciprocates using the compressed gas. Furthermore, such complex firing devices are often difficult to operate and maintain and often suffer breakdowns after extended periods of use. Paintball markers have also been developed that are automatic, i.e. fire repeatedly when the trigger is held back without manual recocking. The advent of automatic paintball markers has resulted in an increase in “ball chop.” Ball chop occurs when the bolt moves forward towards the paintball while the paintball is only partially within the breech. The result is the ball is cut or smashed within the breech of the marker, fouling the paintball marker often entirely disabling it, effectively ending a player's game.
SUMMARYIt is therefore an object of the present invention to provide an electronic paintball marker comprising a breech having an inlet for receiving a paintball; first and second electromagnets disposed within the breech at a distance from each other; a sensor disposed within the breech for detecting the presence of a paintball; a processor in communication with the electromagnets and sensor; and a bolt moveable between the first and second electromagnets, wherein the bolt comprises an elongate body having first and second ends, each of said ends having a magnetic portion and wherein at least one of the electromagnets is actuated by the processor when the sensor detects a paintball, the actuation creating an attraction or a repulsion between the magnetic portion and the at least one electromagnet.
It is also an object of the present invention to provide an electronic paintball marker comprising a breech having first and second ends and an inlet for receiving a paintball; an electromagnet disposed within one of the ends; a sensor for detecting a paintball disposed within the breech; a processor in communication with the electromagnet and the sensor; and a bolt moveable between the sensor and the electromagnet, wherein the bolt comprises an elongate body having first and second ends, at least one of said ends having a magnetic portion and wherein the electromagnet is actuated by the processor when the sensor detects a paintball, the actuation selectively creating an attraction or a repulsion between the magnetic portion and the electromagnet.
It is a further object of the invention to provide a bolt for a paintball marker comprising an elongate body having first and second ends, each end having a magnetic portion, wherein the bolt moves back and forth within a breech of a paintball marker by magnetic forces exerted on the magnetic portions of the bolt.
It is a further object of the present invention to provide for a paintball marker wherein the bolt moves by magnetic attraction or repulsion.
A paintball marker is usually a futuristic “gun-shaped” device having one or two grips for firing, a barrel from which a paintball is discharged, and a trigger for activating the marker to fire the paintball. The actual body and shape of the marker is not shown in the Figures because the invention discussed herein relates to only several components of a marker, and not the body of the marker itself. It should be understood that the invention herein could be adapted for use in almost any paintball marker body. In addition, it should be understood that the various components described herein may be mounted in or on the paintball marker.
Referring to
The bolt 20 of the present invention has an elongate body with first and second ends and a through aperture. The bolt can also comprise at least one magnetic portion 28. The magnetic portion can be formed from a magnetized material that will be attracted to or repelled from a magnet. Any ferrous metal or other material that can be magnetized is acceptable. The magnetic portion 28 may also have a core formed from lightweight plastic and have an outer coating of a ferrous metallic material. Alternately, only the front and rear walls of the magnetized portion 28 need have an outer coating of a ferrous metallic material.
In a “closed bolt” arrangement, as is known in the art of paintball sports, the firing sequence includes trigger pull, signal to move bolt from a firing position to a loading position, loading of paintball, moving bolt from a loading position to firing position, opening valve to allow compressed gas to travel through the aperture in the bolt. Exemplary paintball marker arrangements are shown in U.S. Pat. Nos. 6,474,326 and 6,637,421, the entirety of which are incorporated by reference herein.
A closed-bolt arrangement of the present invention is depicted in
In an open-bolt arrangement is depicted in
When a user pulls the trigger 26, indicating a firing sequence is being initiated, the controller 32 activates sensor 30 to determine if a paintball is in the breech. If it is determined that a paintball 19 is in the breech. The controller 32 will activate the electromagnets 40, 42 to attract and repulse the magnetic portion 28 of the bolt 20 to move the bolt 20 in a forward direction. As above, once in the firing position, the controller 32 opens valve 24 to release a controlled amount of gas from gas source 22 to fire the paintball from the barrel 16.
Alternately, the open-bolt configuration may not rely on a sensor. Thus a firing sequence is initiated when a user pulls the trigger 26. The controller 32 will activate the electromagnets 40, 42 to attract and repulse the magnetic portion 28 of the bolt 20 to move the bolt 20 in a forward direction. As above, once in the firing position, the controller 32 opens valve 24 to release a controlled amount of gas from gas source 22 to fire the paintball from the barrel 16.
The marker 10 of the present invention may also comprise bumpers 52, 72 which serve to protect the magnetic portion 28 from excessive wear from contact with the electromagnets 40, 42. The bumpers can be of an elastomeric material such as rubber and also serve to reduce noise and provide greater comfort to a user.
As shown in
A fourth embodiment is depicted by
The firing sequence may include different steps depending on the embodiment of the paintball marker of the present invention. In simple terms, the firing sequence for a “closed bolt” arrangement may be: (a) trigger actuation; (b) bolt moved rearward to load paintball; (c) bolt moved forward; and (d) valve opened to fire paintball. The firing sequence for an “open bolt” arrangement may be: (a) trigger actuation; (b) bolt moved forward; (c) valve opened to fire paintball; and, (d) bolt returned to “home” (or rearward) position. The movements are controlled by the controller, and the bolt is moved at least in part by magnetic force. Where a spring is used, the spring will bias the bolt or piston to one of either the rearward or forward positions, depending on the arrangement of the magnets and springs.
It should also be contemplated that the bolt can comprise an electromagnet rather than a magnetic portion.
