This invention relates to telescopic gun scopes, specifically to gun scope lens covers that overlie the respective ends of a gun scope protecting it prior to use.
Prior art gun scope caps and covers are used on telescopic rifle scopes that are positioned on top of a rifle having an elongated tube with a plurality of magnifying objective lenses positioned therein for providing an enlarged view of a distance target. It is critical that the lenses in the respective scope ends be protected when not in use. Cover or lens caps have been developed to selectively fit on the scope ends and may be hinged so as to afford ease and quickness of scope use when they are removed.
Examples of dual gun scope lens caps and methods of operating them can be seen in U.S. Pat. Nos. 2,534,061, 2,696,672, 2,738,585, 2,889,629 and 3,496,643.
U.S. Pat. No. 2,534,061 discloses a telescopic site lens cover having a pair of lens caps interconnected by a release bar. Each cap is split with independent hinges and has a spring hinge release by a sliding lever.
U.S. Pat. No. 2,696,672 claims a snap action protection cover for the ends of a telescopic site allowing for instantaneous removal using an elastic band in communication with the respective end cover.
U.S. Pat. No. 2,738,585 illustrates a telescopic scope lens cover device having a pair of hinged covers over the respective ends of a scope with an activation rod and a release button allowing the covers to open.
U.S. Pat. No. 2,889,629 describes an eye piece cover for a gun scope with independent spring hinges which are released and flip open allowing for user visual access.
U.S. Pat. No. 3,496,642 claims a gun scope cover with a dual quick release having an elastic cord between the end covers providing constant resilient pressure when in a hinged closed position. A center release cord activates a sliding latch releasing the cover by the resilient engagement of the cord.
A dual release gun scope lens cover system having an interconnected pair of hinge spring urged lens scope covers each with an integrated magnet for magnetic alignment with a corresponding magnetic enabled retainment and release rod movable from a magnetic attraction retainment cap cover closed position to a magnetic opposing release cover open position simultaneously by manual engagement of an offset rod crank for axial rotation input thereto.
Referring to
The gun scope lens cover assembly 10 has an eye piece lens cover 14 and a front-end cover 15 which are hinged at 14A and 15A to respective cylindrical eye piece mounting member 16 and end mounting member 17 on the respective eye piece and front ends 13A and 14A of the gun scope 11.
The hinge fittings 14A and 15A extend from the corresponding cylindrical mounting members 16 and 17 so as to allow rotation of the respective lens covers 180 degrees to afford the user, not shown, to fully see the scope field when in operation as seen in
The mounting members 16 and 17 are coupled together by an activation control rod 18 that is registerably received in apertures 19 in the respective mounting members 16 and 17. The receiving apertures 19 are formed in lug portions 20 extending from the respective mounting members 16 and 17 providing longitudinal support and rotational retainment thereof.
The control and activation rod 18 has an offset lever arm 21 that extends in spaced parallel longitudinal relation to the apertured lug portions 20, best seen in
Magnets 22 are positioned in both free ends of the rod 18 defining the magnetic pole thereof. Correspondingly, magnets 23 are positioned in respective apertured tabs 24 on the respective covers 14 and 15 in alignment with the rod end magnets 24 when in closed position illustrated in
It will be evident therefore that the magnetic pairs 23 are used to hold the lens caps 14 and 15 by magnetic attraction in closed position on the gun scope ends 13A and 13B and correspondingly to release the lens covers 14 and 15 under their spring urged hinge 14A and 15A to rotate to open viewing position of the scope as seen in
The release of the magnetic attraction of the opposing magnetic poles N pole to S south pole for the attraction force of magnets is defines as magnetism and the space around the magnets is defined as magnetic field within the art.
It will therefore be seen that by aligning the respective magnetic poles and the magnetic field in attraction, N pole to S pole, or repulsing N pole to north and S pole to south, and effective positional retainment or release of the lens cap covers 14 and 15 can be achieved through the activation and control rod 18.
Given that the orientation of the magnetic field is fixed in the lens cover, positioned magnets 23, the rotation of the magnets 24 in the respective rod 18 ends, as hereinbefore described, affords the change in attraction to repulsion indicated in
It will be seen that in operation the gun scope lens cover assembly 10 provides initial closed end cover position held in place by the magnetic attraction achieved by the respective rod end magnets 24 and cover magnets 23 orientation as seen in
It will thus be seen that a new and novel gun scope cap assembly gun cover assembly 10 of the invention has been illustrated and described and it will be apparent to those skilled in the art that various changes and modification may be made thereto without departing from the spirit of the invention.
