US 5,272,955 A · Gun aiming device for a wheelchair

Abstract

A portable apparatus attachable to a wheelchair for movably supporting a gun thereon includes a pneumatic/hydraulic fluid operated control circuit for operably controlling the direction of the gun while sitting in the wheelchair. The apparatus includes a support adapted to attach to the wheelchair and support a gun, and further includes a control system including a hydraulic linear actuator and a hydraulic rotary actuator operably connected to the support, an air tank operably connected through control valves and air/oil chambers to the actuators, and controls including a joystick which can be readily manipulated by the person in the wheelchair to move the control valves and thereby controllably actuate the actuators to aim the gun. A pair of oil interlock valves are operably connected to either side of each of the actuators to securely locate the gun in a given position once aimed.

Dependent claims

An apparatus for sue by a wheelchair-bound person to aim and fire a gun while sitting in a wheelchair comprising:

a base adapted to attach to the wheelchair;
a gun support adapted to securely attach to and support the gun, said gun support being movably connected to said base so that the gun can be aimed in different directions;
at least one fluid operated actuator operably connected to said gun support for controllably moving the gun to aim the gun;
fluid power means for powering said one actuator including means for mounting said fluid power means to the wheelchair;
and
control means operably connected to said fluid power means and said one actuator for controlling said one actuator, said control means being adapted for use by the wheelchair-bound person.

3 more elements

A portable control system for aiming a gun operably mounted on a gun support, comprising:

portable fluid actuating means adapted to operably connect to the gun support for aiming the gun located on the gun support;
portable powering means operably connected to said portably fluid actuating means for powering said portable fluid actuating means;
a portable control system to control said portable fluid actuating means, said control system including valve means operably connected to said portable powering means and said portable fluid actuating means for controlling same, said control system further including a lever means operably connected to said valve means and being manipulatable so as to shift said valve means;
whereby a person can aim the gun mounted on the gun support by manipulating the lever means so as to control said portable fluid actuating means and, in turn, the gun support;
and
means for attaching said portable fluid actuating means, said portable powering means, and said portable control system to a wheelchair.

A portable control system for aiming a gun operably mounted on a gun support, comprising:

portable fluid actuating means adapted to operably connect to the gun support for aiming the gun located on the gun support;
portable powering means operably connected to said portable fluid actuating means for powering said portable fluid actuating means;
and
a portable control system to control said portable fluid actuating means, said control system including valve means operably connected to said portable powering means and said portable fluid actuating means for controlling same, said control system further including a lever means operably connected to said valve means and being manipulatable so as to shift said valve means;
whereby a person can aim a gun mounted on the gun support by manipulating the lever means so as to control said portable fluid actuating means and, in turn, the gun support;
said portable powering means including a compressed air source and at least one air/oil chamber for converting compressed air fluid flow into incompressible fluid flow, said at least one air/oil chamber being operably interconnected with said portable fluid actuating means, whereby compressed air from the compressed air source can be converted to hydraulic power for powering said portable fluid actuating means such that the gun may be accurately aimed with a volume of incompressible fluid exiting from said portable fluid actuating means being converted to a volume of air which is released to atmosphere as said portable fluid actuating means is moved.
