Abstract
A rotating optical mount for firearms that allows the user to install two completely different optical devices on the same firearm and easily switch between the two. As each optical device is rotated in the top center position of the apparatus it will latch into a predetermined and repeatable position allowing the user to maintain proper projectile placement with previously made adjustments to the optical device. Operators can quickly and easily switch between an optical device for distance engagement to an optical device for close quarters engagement and visa-versa by rotating the apparatus in the appropriate direction to place the desired optical device in optimum position while with the same action, moving the previously desired optical device away from the optimum position.

BACKGROUND OF THE INVENTION

This invention relates to the mounting of various accessories such as optical devices to a firearm.


Firearms allow the use of a wide variety of optical devices such as riflescopes, telescopic sight, aperture sights, red dot sights and holographic sights in order to accurately place the projectile at the intended location. In order to accomplish this, the optical device should be mounted on top of the firearm with the centerline matching that of the projectile travel path centerline. The optical device must be adjusted based on each independent user's positioning, line of sight as they aim through the optical as well as varying environmental conditions.


Different situations require the use of different types and configurations of optical devices. Optical devices that are intended to allow the user to accurately engage targets at a distance do not allow for the ability to accurately engage targets at close range. In order to accomplish this, many users install a second optical device at a 45° offsets to the firearm centerline or stack one optical configuration on top of another one. This adversely affects the accuracy and ease of use of the firearm.


There is a need for an optical device mount that can be adapted to any firearm that allows the user to install two independent optical devices on the firearm simultaneously. The mount must allow for quick transition between the two and ensure the desired optical device is positioned in the proper centerline as to maintain the user's accuracy and sight picture. It must have versatility of design to enable users to install a variety of different optical devices.


BRIEF SUMMARY OF THE INVENTION

The utility concept and designs enclosed are for an optical device mount that meets and exceeds the current need. The mount must allow for quick transition between two independent optical devices while maintaining the operator's accuracy settings “zero”. Standard aperture sights can also be added in conjunction or incorporated into the optical mount to allow for three independent sight devices on the same firearm.


Rotating the mounting cylinder will bring the desired optical device to centerline firing position while moving the previous optical device off to the side. The mounting cylinder will latch into a repeatable position; therefore maintaining accuracy and centerline of either optical devices rotated into the centerline position. Firearms can be simultaneously set-up for close quarters use as well as distance shooting. The mounting cylinder can be rotated into a position between the optical devices allowing for a clean line of sight thorough hard (iron) sights.

OPERATION OF THE INCLUDED EMBODIMENTS
Embodiment Example 1

The following operational description is to aid the reader in understanding the function and operation of the invention demonstrated in Figures one through six. It does not limit the invented device to a particular embodiment or specific method of operation.


The user mounts the apparatus to the firearm by attaching the mounting brackets 1 to the top portion of the firearm.


The user mounts the first optical device to the top optical rail 6 attached to the mounting cylinder 5 by use of the rail mounting screws 7.


The user mounts the second optical device to the optical rail 6 attached on the side of the mounting cylinder 5 ninety degrees circumferentially from the first optical device.


The user makes the necessary adjustments to the first optical device to “sight in” the accessory.


The user rotates the mounting cylinder 5 circumferentially in the direction of travel that will place the second optical device on top of the apparatus.

    • As rotational torque is applied to the mounting cylinder 5, the detent portion of the spring plunger 3 is depressed, allowing free rotation of the mounting cylinder 5.
    • As the mounting cylinder 5 begins to rotate circumferentially, the thrust bearings 4 in the mounting cylinder 5 begin to rotate around the axis of the shaft 2 that is held in place by the shaft retaining screws 8.
    • Once the mounting cylinder 5 is rotated ninety degrees, the spring plunger 3 will extend into the locating hole in the mounting cylinder 5 thereby latching the mounting cylinder 5 into position.
    • The user makes the necessary adjustments to the second optical device to “sight in” the accessory.
    • The user switches between the two optical devices by rotating the mounting cylinder 5 in the appropriate direction to place the desired optical device on top of the apparatus.
    • As the apparatus latches into a repeatable position, re-adjustment of the two optical devices is unnecessary.


The following operational description is to aid the reader in understanding the function and operation of the invention demonstrated in Figures seven and eight. It does not limit the invented device to a particular embodiment or specific method of operation.


Embodiment Example 2

The following operational description is to aid the reader in understanding the function and operation of the invention demonstrated in Figures seven and eight. It does not limit the invented device to a particular embodiment or specific method of operation.


The user mounts the apparatus to the firearm by attaching the mounting brackets (not shown) to the top portion of the firearm.


The user mounts the first optical device to the top optical rail 6 attached to the mounting cylinder 5 by use of the rail mounting screws 7.


The user mounts the second optical device to the optical rail 6 attached on the side of the mounting cylinder 5 ninety degrees circumferentially from the first optical device.


The user makes the necessary adjustments to the first optical device to “sight in” the accessory.


The user pulls the main body of the device towards the user by which the following actions occur:

    • The main body including the mounting cylinder 5 and all components connected moved to the rear towards the user.
    • The exit shaft 8 connected to the mounting cylinder moves horizontally in the same plane retracting with the main body.
    • As the main body moves, the stationary entry shaft 12 extends further inside the mounting cylinder 5.
    • The spring adjusting screw 11 connected to the entry shaft 12 moves further inside the mounting cylinder 5 further compressing the spring 14.
    • The moving of the main body towards the user disengages the mounting cylinder 5 locating holes from the positioning nuts 2 thereby disengaging the positive positioning.


The user rotates the main body of the device in the appropriate direction to move the second optical device to the top of the device.


Once the second optical device is in the approximate top center position, the user releases reward pressure on the device allowing the spring 14 to move the main body forward thereby re-engaging the mounting cylinder 5 onto the positioning nuts 2 by insertion into the corresponding indentations in the mounting cylinder 5.


The user makes the necessary adjustments to the second optical device to “sight in” the accessory.


At this time, the user may interchange between the two optical devices by repeating the actions stated above to disengage, rotate and re-engage the positive positioning locking function.

    • Competition Shooting Firearms

    • Hunting Firearms and bows

    • Recreational Shooting Firearms

    • Self Defense Firearms
