A paintball marker comprises a main bodya barreldefining a firing axis X-X, and a grip frame assembly including a frameand a triggerpivotably mounted in the frameThe trigger has an upper finger engaging portionand a lower finger engaging portionso that it can be operated by two fingersThe lower finger engaging portionis curved round so that its finger engaging surfaceends in a horizontal partThe pivot axis of the trigger is adjustable between a number of positions, one of which is offset to the rear of the finger engaging portionsso that the trigger can be operated by pulling downwards on the horizontal partof the finger engaging surface

Paintball marker

A control system for a paintball marker having a breach, the control system comprising a contact sensor, a controller, and a paintball firing mechanism, the sensor being arranged to be located within the paintball marker, to sense a paintball being in contact therewith and to produce a signal indicative of the presence of the paintball within the breech, and the controller being arranged to receive the signal and to control the actuation of the firing mechanism in response to the signal.

Paintball marker control system

A paintball gun is disclosed which includes a data link for transferring data to and/or from a remote terminal. The link may be a contact or contactless one. A removable data carrier may be used.

Paintball guns

An electronically controlled pneumatic paintball gun, comprising means for monitoring and/or controlling one or more parameters of the gun's operation and alphanumeric display means for displaying data related to said monitoring or control on a display panel integral with the gun.

An electronically controlled pneumatic paintball gun. The paintball gun includes an apparatus for monitoring and/or controlling one or more paramaters of the gun's operation. The gun also includes a system for providing information to a user related to the monitoring or control, including but note limited to firing mode, valve dwell time, ambient temperature, whether the gun is in live or safe mode, whether or not a fault has been detected, maximum rate of fire, battery status, and combinations thereof.

A paintball feed system ( ) comprises flexible detent beams ( ) that flex about first and second support points ( ) such that they allow a paintball ( ) to pass from a hopper ( ) into a feed tube ( ) leading to a paintball marker's breech ( ) under it's own weight when flexing about the first support point ( ). The beams ( ) are rigid enough, when flexing about the second support pint ( ), to prevent the return of the paintball ( ) back into the hopper ( ) from the feed tube ( ).

Paintball marker grip frame

A paintball gun is disclosed which includes a data link for transferring data to and/of from a remote terminal. The link may be a contact or contactless one. A removable data carrier may be used.

A gas regulator, relating in particular to a regulator for a gas or air cylinders, for supplying compressed air to a paintball gun or other compressed air powered projectile firing devices. A micro controller operably associated with the gas regulator is adapted to generate a shots remaining signal by receiving a pressure drop signal from a pressure transducer and a set of shot fired signals corresponding to the gas pressure drop signal. A method is also provided for generating the shots remaining signal using a second gas cylinder temperature signal, a temperature compensated shots remaining calibration constant and a gas regulator input pressure signal.

Gas regulator

A paint ball gun is connected through a first gas pressure regulator to a supply of pressurized gas for maintaining a high gas pressure in a first chamber in the gun and a second gas pressure regulator is connected between the first chamber and a second chamber in the gun to maintain a working gas pressure in the second chamber greater than atmospheric pressure but less than the gas pressure in the first chamber. A pneumatic control valve is arranged to receive gas under pressure from the second chamber and direct it selectively to a pneumatic ram mounted for sliding movement in a cylinder in the gun between a retracted position and a forward position in which it opens a valve to admit high pressure gas from the first chamber to the barrel to fire a paint ball. An electrical switch for the control valve is connected to an electronic control circuit which incorporates a micro-switch operated by the trigger of the gun.
