Easy-on, easy-off sighting aid mount for a revolver

摘要

In revolvers that are loaded by swinging or shifting the revolver's cylinder away from alignment with the barrel, an extension of the cantilevered axle pin (upon which the cylinder rotates when the revolver is fired) can be sufficiently exposed so that a specially crafted mounting device can be connected to the axle pin. Connection is accomplished by simply sliding the mounting device longitudinally over the distal end of the pin (or an extension thereof). A common extension of the cylinder's axle is an ejector rod that is used to eject spent shells from a cylinder. Typical ejector rods have both the strength and the precision that makes them well suited to function as anchors for a mounting device. When a cylinder and its axle pin are rotated back to a closed position with respect to the revolver's frame, the mounting device is captured by rigid parts of the revolver (e.g., the barrel and/or a part of the frame)--so that the device will remain fixed until the cylinder is again opened. By attaching an auxiliary sighting aid (such as a laser) to such a mounting device, the sighting aid can be reliably and repeatedly attached to a revolver without the use of any screws or nuts or other mechanical fasteners. The elapsed time that is required to slide a mounting device over the exposed end of an axle pin or ejector rod is on the order of a few seconds. Removing the mounting device and its attached sighting aid is equally fast, thereby restoring the revolver to its factory-original condition without leaving any evidence that a sighting aid was ever mounted on the gun.
