摘要:
The present invention relates to firearms requiring the smooth operation of slidably engaged subassemblies for effecting projectile loading, maintenance, triggering, discharge, or reloading of a projectile. The major drawback of the prior art, such as that applying to slide-action pistols, is that friction occurs unevenly and at high levels between moving parts, which leads to damaging levels of frictive heat, wear, or warping, as well as jamming. The slidable guidance system proposed herein addresses this drawback by employing micro-rollers whose surfaces do not at any one point constantly touch the slidable gun part(s) with which they come in contact. Preferably, at least a set of micro-rollers and a pair of channels are installed in the inner sides of a slide and the upper outer sides of a gun frame, or on the lower face of a slide-housed slidable barrel and the upper face of a gun frame.

A shock absorbing disruptor mounting system for a robotic arm includes a rack comprised of a linear guide structure and a carriage which is configured to travel on the linear guide structure. The carriage is selectively movable between a retracted position and an extended position and includes a plurality of wheels along its length. Each of the wheels has a wheel axis of rotation which is transverse to the direction of the linear guide structure centerline to facilitate rotation of the wheels on at least a portion of the linear guide structure responsive to the travel.

An accelerating assembly effectively to increase the cyclic rate at which the trigger of a semi-automatic firearm can be actuated to discharge the weapon. The firearm has a supporting device, a receiver housing supported from the supporting device, a trigger and trigger mechanism secured to the receiver housing. The accelerating mechanism incorporates structure that permits the receiver and the trigger to translate rearwardly a predetermined distance with respect to the supporting device in response to the recoil imparted by the discharge of the semi-automatic firearm. A biasing arrangement continuously urges the receiver, and trigger, to translate forwardly with respect to the supporting device substantially that same predetermined distance. A locating stop is mounted on the supporting device. The locating stop is disposed to be engaged by the shooter's finger after the trigger has been actuated to fire the semi-automatic weapon. That engagement of the shooter's trigger finger with the locating stop effectively immobilizing the shooter's trigger finger with respect to the supporting device until the shooter releases the trigger. The method of the present invention operates by depressing the trigger with a shooter's trigger finger in order to discharge the firearm. The shooter's finger is then immobilized in the position it has assumed to discharge the firearm. The trigger is translated away from the immobilized trigger finger to effect a total disengagement therebetween. Sequentially thereafter the trigger is biased into engagement with the immobilized trigger finger to effect successive discharges of the firearm.

A rolling bearing arrangement for guidance of a gun barrel during longitudinal displacement comprising a gun barrel having at least three circumferential axis-parallel strips projecting radially outward, each strip having two bearing surfaces parallel to each other and to a radial plane, which in turn are associated with directly opposite bearing surfaces extending parallel thereto in a housing surrounding the gun barrel, and a flat cage containing a set of cylindrical rollers arranged between the directly opposite bearing surfaces, the two sets of rollers cooperating with a common strip being under tension by the arrangement, displaceable in a parallel manner, by at least one element carrying a bearing surface.

A guide system for the longitudinal recoil movement of a cannon has a pair of guide units spaced apart along the cannon barrel and each having a plurality of rollers angularly spaced about the barrel. At least one roller is elastically biased against the barrel while other rollers of the units are radially fixed to provide firm guidance of the barrel without play under all conditions and enabling the yieldable roller to adjust to the increase in barrel size with increasing temperature resulting from firing of the weapon.

A compressed gas- or air-operated firearm, comprises a gun stock with a gun sleeve affixed to the gun stock and with a gun barrel having an associated compression cylinder adjacent the inner end thereof with a spring-actuated piston movable therein and an associated trigger mechanism which is movably supported within the gun sleeve by roller bearing structure. A power accumulator is arranged between the relatively movable parts and it biases the parts into a neutral position and includes structure for absorbing the reaction force due to the movement of the piston during operation of the weapon.

A machine gun, representatively a 30 mm machine gun, is mounted on an outer end portion of a support plank structure projecting out of the cabin area of a helicopter using a roller cradle assembly secured to the outer plank end. A variety of structural improvements are incorporated into the machine gun to (1) reduce its mechanical complexity, (2) reduce its firing recoil to make the gun more suitable for light aircraft mounting, and to improve the gun's firing controllability and accuracy, and (3) to make the gun easily and quickly field strippable, for cleaning, inspection and repair purposes, without requiring the services of a highly skilled armament mechanic or taking the gun to a specialized repair facility.
