PNEUMATICALLY TIMED CONTROL UNIT FOR A GAS OPERATED PROJECTILE
LAUNCHING DEVICE
Abstract
A pneumatically timed control unit controls a gas operated
projectile launching device. At rest, the control unit feeds
pneumatic gas from a compressed gas supply to the launching
device's loading, launching components and/or mechanisms, and/or
gas storage chamber(s). Once the valve is partially activated, the
control unit uses pneumatic pressure from the gas storage device to
urge the valve to a fully activated position to start the launching
and/or loading sequences of the launching device and to
pneumatically hold the valve(s) within the control unit in the
activated position. The control unit waits for pneumatic feedback
and/or absence of feedback/exhausting pneumatic pressure from
either the launching device's loading and/or launching components
and/or mechanism, or from a gas storage chamber and/or a venting
relief-type valve to release the pneumatic hold on the valve. This
allows the valve to be shifted to the "at rest" position, ready for
the next activation sequence.

Description
BACKGROUND OF THE INVENTION
[0001] The present invention relates to projectile launching
devices and, more particularly, to a pneumatically timed control
unit for a gas operated projected launching device.
[0002] Currently, controlling the fire sequence of a gas operated
projectile launching device falls under two basic categories. First
is the need for highly complex electro-pneumatic flow distribution
devices consisting of electronic solenoids and or circuit boards,
and second is a mesh of mechanical pneumatic firing systems, like
for instance the use of pistons, hammers, springs, and sears.
[0003] As can be seen, there is a need for an improved system for
controlling and operating a gas operated projectile launching
device.
SUMMARY OF THE INVENTION
[0004] In one aspect of the present invention, a pneumatically
timed control unit assembly for a gas operated projectile launching
device comprises a valve urged in an at rest position; and a gas
storage device operable to receive pneumatic pressure through the
control unit in the at rest position from a compressed gas supply,
wherein when the valve is moved to a partially activated position,
pneumatic pressure from the gas storage device urges the valve to a
fully activated position, wherein a Gas Operated projectile
launching device receives gas pressure from the gas storage device
and or compressed gas supply to activate it's firing sequence. Then
the pneumatically timed control unit waits for pneumatic feedback
and or absence of feedback/exhaust from either the Gas Operated
Projectile launching Device's loading and or launching components
and or mechanisms, and or Gas storage device and or a venting
relief type valve to release the pneumatic hold on the
pneumatically timed control units valve, which allows the valve to
be shifted to the "at Rest" position ready for the next activation
sequence.
[0005] In another aspect of the present invention, a method for
launching a projectile from a projectile launching device comprises
receiving a compressed gas supply to a valve; delivering the
compressed gas supply to at least one of a compressed gas storage
device and or a firing chamber of a launching device when the valve
is in an at rest position; activating an activation mechanism, the
activation mechanism operable to activate a valve in a control
unit; urging the valve into an activated position as the activation
mechanism is activated to actuate the valve by delivering gas
pressure from at least one of the compressed gas storage device and
the firing chamber of the launching device; and delivering gas
pressure and or exhaust to the launching device.
[0006] These and other features, aspects and advantages of the
present invention will become better understood with reference to
the following drawings, description and claims.

DETAILED DESCRIPTION OF THE INVENTION
[0021] The following detailed description is of the best currently
contemplated modes of carrying out exemplary embodiments of the
invention. The description is not to be taken in a limiting sense,
but is made merely for the purpose of illustrating the general
principles of the invention, since the scope of the invention is
best defined by the appended claims.
[0022] Broadly, an embodiment of the present invention provides a
pneumatically timed control unit (also referred to as the control
unit) for a gas operated projectile launching device (also referred
to as the launching device). At rest (FIGS. 6, 9 and 12), the
control unit feeds pneumatic gas from a compressed gas supply to
the launching device's loading and/or launching components and/or
mechanisms and/or gas storage chamber(s). Once the valve is
partially activated (FIGS. 7, 10 and 13), the control unit uses
pneumatic pressure from the gas storage device to urge the valve to
a fully activated position to start the launching and/or loading
sequences of the launching device and the pneumatically hold the
valve(s) within the control unit in the activated position. Then,
the control unit waits for pneumatic feedback and/or absence of
pneumatic feedback from either the launching device's loading
and/or launching components and/or mechanism, or from a gas storage
chamber and/or a venting relief-type valve to release the pneumatic
hold on the control unit's valve (FIGS. 8, 11 and 14). This allows
the valve to be shifted to the "at rest" position, ready for the
next activation sequence.
[0023] The control unit for launching devices may be configured to
retrofit into an existing launching device or can be configured as
an integral control unit of a launching device's assembly.
[0024] Referring now to FIGS. 1 through 5, a user may activate a
trigger/actuator 04 to activate a valve in a control unit 06/08.
Alternatively, a secondary ram, controlled by a pneumatic pulse
generating valve and/or shuttle valve 16 may activate the valve in
the control unit 06/08. The valve may receive a compressed gas
supply 18. The control unit 06/08 can include valves 06 and a
housing 08.
[0025] In the "at rest" position (FIGS. 6, 9 and 12), gas from the
compressed gas supply 18 may be delivered to, for example, a gas
storage device 14 and/or a firing chamber of a launching device 02.
A metering valve 20 may be optionally present to meter the gas flow
to and/or from the gas storage device 14. As the valve is actuated,
gas pressure from the gas storage device 14 and/or firing chamber
may urge the valve to an activated position. A pneumatic linkage
device and/or integrated porting and/or hoses 12 may deliver gas
pressure to and or from the launching device 02. This gas pressure
may be delivered through an optional pneumatic solenoid 10.
[0026] Valve(s) 06 may comprise sealing member(s) to direct gas
into inlets and or outlets within the valve body and/or housing 08
which may also comprise sealing members. The valve 06 may include
opposing pneumatic forces, whether by area differences and or
pressure differences applied to the valve 06, directly and/or
indirectly from the compressed gas supply 18 and/or pneumatic
feedback and/or absence of feedback/exhausting from the launching
device 02 for shifting the "at rest" and/or "activated" position(s)
of the valve 06 within the valve housing 08. The valve 06 may also
include the use of springs for resetting the "at rest" and/or
"activated" position(s) of the valve 06 within the valve housing
08.
[0027] Once the control unit has been activated, and the launching
device has been fired, the valve 06 may detect the reduction in
pressure in, for example, the gas storage chamber, and allow the
valve to release it's pneumatic hold on the valve and to reset to
the "at rest" position. If the launching device does not fire after
the valve 06 has been activated, gas may be vented from the control
unit, optionally through a flow restricted exhaust and/or metering
valve 20, releasing its pneumatic hold on the valve 06 and allowing
the valve to reset to the "at rest" position ready for the next
activation sequence.
[0028] The control unit 06/08 can, directly or indirectly control
the operation of the launching device 02 by having a valve or
plurality of valves 06 with pneumatic input port(s) to the valve
housing 08 that may receive compressed gas from a compressed gas
supply 18 and an output port(s) pneumatically linked 12 to a
pneumatic component(s) and or mechanism(s) to initiate the loading
and or launching operation of the launching device 02.
[0029] For instance, the control unit 06/08 can contain a network
of pneumatic components configured to receive activation from a
trigger and/or actuator 04, to send and or receive pneumatic
signal(s) by means of pneumatic linkage 12 to a pneumatic solenoid
valve(s) 10. The pneumatic solenoid valve(s) 10 can, for instance,
direct compressed gas and or exhaust pneumatic pressure by means of
pneumatic linkage 12 to and/or from the pneumatic loading and or
launching components and/or mechanism(s) of the launching device 02
to operate the pneumatic components and/or mechanism(s) in response
to the pneumatic signal from the control unit 06/08. The
trigger/actuator 04 may be mounted to slide and/or pivot in such a
manner as to make contact with the valve(s) 06 of the control unit
for starting and/or stopping the control unit's pneumatic output
and or input sequence(s).
[0030] The control unit 06/08 may include an adjustable and/or
fixed pneumatic time delay signal for completing the loading and/or
launching operation of the launching device 02, typically by use of
fixed, and/or adjustable pneumatic flow restricting devices 20.
[0031] The gas storage device 14, fixed and/or adjustable in volume
and/or pressure, and or flow, may be used in conjunction with
and/or separately from the pneumatic feedback 12 from the launching
device 02 to store and/or release gas to and/or from the control
unit 06/08 in such a manner as to apply adjustable and/or fixed,
momentary pneumatic pressure to the control unit 06/08 for
pneumatically holding and/or releasing the valve 06, therefore
producing timing control of the launching device, and/or a means
for metering the output and/or input and or exhaust of the gas
storage device 14. The control unit 06/08 can be shaped to mount
and/or assemble within the body and/or frame of the launching
device 02. The control unit 06/08 can be arranged to send one or
more timed pneumatic signals to initiate the loading and/or
launching operation(s) of the launching device in response to the
trigger 04 pull and/or release of the trigger 04 pull.
[0032] Compressed gas 18 may supply pneumatic pressure to the
control unit 06/08. The trigger/actuator 04 (which may not need to
be present for functionality) can, for instance, be manually acted
upon to depress the valve 06 within the control unit valve body
and/or housing 08.
[0033] The control unit valve(s) 06 and valve housing 08 may
redirect pneumatic gas and or exhaust thru pneumatic linkage 12, to
and/or from the pneumatic component(s) and/or mechanism(s) of the
launching device 02 to activate the pneumatic sequence of events
that initiate the loading and/or launching operation(s) of the
launching device 02. The launching device 02 may also direct
pneumatic pressure and/or exhaust of pressure from its pneumatic
component(s) and/or mechanism(s) that initiated its loading and/or
launching operation(s) back to the control unit 06/08 thru the
pneumatic linkage 12 for use of pneumatically activating and/or
deactivating the valve 06 position(s) within the control unit valve
housing 08.
[0034] The control unit 06/08 may be comprised to redirect
pneumatic gas pressure to and/or from a pneumatic solenoid(s) 10
(which may in some cases not need be present for functionality),
where the pneumatic solenoid(s) 10 may be configured to activate
the pneumatic sequence of events to initiate the loading and/or
launching operation of the launching device 02 in response to a
trigger 04 pull and/or release of a trigger 04 pull of the control
unit.
[0035] The pneumatically timed control unit assembly 06/08 could be
used in various applications, such as military applications, the
paintball industry, the toy industry, scuba, and or pneumatic
tooling industries, to name a few. The pneumatically timed control
unit invention enables pneumatic timing control of a gas operated
projectile launching device 02, by a choice of two applications, or
combination of both, one being pneumatic feedback, or absence of
feedback, to the pneumatically timed control unit assembly 06/08
from the gas operated projectile launching device 02 and its
pneumatic component(s) and/or mechanism(s) and/or two, a gas
storage device 14, possibly adjustable and/or fixed in volume
and/or pressure, both used to store and/or release gas in such a
manner as to apply adjustable and/or fixed momentary pneumatic
pressure and/or exhaust of pressure to the pneumatically timed
control units valve 06 by pneumatically activating and/or
deactivating the valve 06 positions within the pneumatically timed
control unit's valve body and/or housing 08 for loading and/or
launching control of the gas operated projectile launching device
02.
[0036] It should be understood, of course, that the foregoing
relates to exemplary embodiments of the invention and that
modifications may be made without departing from the spirit and
scope of the invention as set forth in the following claims.
