ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a firearm scope that may be quickly focused with a shooter's trigger finger.
DESCRIPTION OF THE PRIOR ART
When focusing a rifle scope on an intended target, a shooter must remove his trigger hand from the trigger and rotate a focusing ring on the scope housing while aiming the rifle at the target. Once the scope is in focus, he or she must move the hand back toward the trigger in order to shoot which is inconvenient, cumbersome and time consuming. In addition, certain game may be easily frightened by such movement.
Various focusing assemblies for rifle scopes have been developed in an attempt to overcome this problem. For example, U.S. Pat. No. 5,180,875 issued to Berry, Jr. et. al. relates to a scope adjustment for firearms including a thumb wheel for focusing the scope with the shooter's trigger hand.
U.S. Pat. No. 5,276,554 issued to Nassivera relates to a magnification adjustment system for a variable power rifle scope. The device includes a multi-purpose lever which may be easily manipulated by the thumb of a shooter's trigger hand for adjusting the focus of the scope.
U.S. Pat. No. 5,521,757 issued to Olson relates to an adjustment lever that may be pushed to rotate the adjustment ring.
U.S. Pat. No. 5,528,847 issued to Fisher et al relates to a variable power telescopic sight.
U.S. Pat. No. 5,020,262 issued to Pena relates to a camera mount for rifle scopes whereby the camera is activated when the rifle trigger is pulled.
U.S. Pat. No. 4,290,219 issued to Boller et al relates to a target sight recording apparatus.
As indicated above, various rifle scope adjustment mechanisms have been developed that allow a shooter to focus the scope without removing his or her hand from the trigger. However, the above devices have several disadvantages. The focusing is accomplished with the shooter's thumb. Manipulating the focusing mechanism with one's thumb while maintaining the trigger finger on the trigger is awkward and cumbersome. Furthermore, while focusing with one's thumb, the firearm trigger may be inadvertently pulled. The present invention solves the above described problem associated with conventional firearm scopes by providing a focusing assembly that is manipulated with a trigger member mounted adjacent the firearm trigger. Accordingly, a user may quickly and inconspicuously focus the scope using the trigger finger, without removing the trigger hand from the firearm.
SUMMARY OF THE INVENTION
The present invention relates to a quick focus firearm scope. The device includes a scope attached to the upper surface of a gun barrel having a focusing gear attached to the scope housing. The focusing gear replaces the focusing ring on a conventional rifle scope. The device also includes a mounting bracket attached to the firearm trigger guard. Attached to the mounting bracket is a substantially U-shaped support member having a trigger member pivotally mounted to its lower portion. The trigger member includes a finger receiving loop at a lower end and an arcuate gear member at its upper end. Downwardly depending from the upper portion of the support member is a rotary gear that engages the arcuate gear on the trigger member. The rotary gear is connected to an end of a cable that has a drive gear at its opposing end. The drive gear is mounted to the scope adjacent the focusing gear on the scope housing. Accordingly, the scope may be focused by inserting the trigger finger into the finger loop and pivoting the trigger member in either direction. It is therefore an object of the present invention to provide a firearm scope that may be focused with a shooter's trigger finger.
It is yet another object of the present invention to provide a firearm scope that allows a user to focus a scope without removing the trigger hand from a firing position.
It is yet another object of the present invention to provide a firearm scope that allows a shooter to quickly focus and shoot with minimal movement. Other objects, features and advantages of the present invention will become readily apparent from the following detailed description of the preferred embodiment when considered with the attached drawings and the appended claims.
