Clamping system for mounting optical devices onto a picatinny-rail

1. A clamping system for removably clamping accessory devices onto a Picatinny-rail characterized in that the clamping system comprises at least one body ( 1 ), which is passed through by one of a cross bolt ( 7 ) or a cross screw ( 8 ), and wherein said one of said cross bolt ( 7 ) or said cross screw ( 8 ) have a stop bar ( 14 a or 14 b ), which engages in a cross slot ( 18 ) in said Picatinny-rail when said clamping system is mounted to said Picatinny-rail ( 10 ), wherein said engagement is configured to occur in a lateral area ( 22 ) of said cross slot ( 18 ) and configured to be a full contact engagement, wherein at least one of a head ( 23 b ) of the cross bolt ( 7 ) or a head ( 23 a ) of the cross screw ( 8 ) is configured to be supported by the lateral area ( 22 ) of the at least one body ( 1 ) thereby preventing the one of said cross bolt ( 7 ) or said cross screw ( 8 ) from shifting across the body ( 1 ) when a clamping force is adjusted by an adjustment screw ( 13 ) at an opposite side of the head ( 23 b ) or when a clamping lever ( 5 ) is operated.

2. The Clamping system as in claim 1 , characterized in said body ( 1 ) is assigned to at least one counterboring ( 15 a ; 15 b ) for a screw ( 16 a ; 16 b ).

3. The clamping system as in claim 1 , characterized in that said cross bolt ( 7 ) can pass through an aperture ( 27 ) of a clamping element ( 4 ).

4. The clamping system as in claim 1 , characterized in that said cross bolt ( 7 ) comprises an internal thread ( 59 ) with an adjustment screw ( 13 ) on the opposite side of said head ( 23 b ).

5. The clamping system as in claim 4 , characterized in that said adjustment screw ( 13 ) is secured by a thread lock ( 25 ).

6. The clamping system as in claim 1 , characterized in that a hinge pin ( 24 ) is divided into a small cylindrical segment ( 36 ), a square ( 37 ) and a large cylindrical segment ( 38 ), whereby a diameter of said small cylindrical segment ( 36 ) is smaller than or as small as the size of said square ( 37 ) and wherein a diameter of said large cylindrical segment ( 38 ) is larger than the size of said square ( 37 ).

7. The clamping system as in claim 6 , characterized in that said cross bolt ( 7 ) comprises an oblong hole ( 39 ), where said square ( 37 ) of said hinge pin ( 24 ) is slidably guided.

8. The clamping system as in claim 1 , characterized in that a safety catch ( 6 ) passes through a slanted aperture ( 30 ) and is pivoted in said locking lever ( 5 ) by means of a piston ( 31 ) and encompasses a lug ( 49 a or 49 b ) with its contact area ( 48 ) of claw ( 11 ) when clamped into said Picatinny-rail.

9. The clamping system as in claim 1 , characterized in that it comprises a nut ( 3 ) at a cross screw ( 8 ) for its handling.

10. The clamping system as in claim 1 , characterized in that said cross bolt ( 7 ) or said cross screw ( 8 ) are fixed in the body ( 1 ) by means selected from the group consisting of screwing, calking and gluing.

11. A clamping system for removably clamping accessory devices onto a mounting rail, said mounting rail having a top surface and a bottom surface, said top surface having a plurality of generally evenly spaced raised protrusions and wherein said top surface includes a plurality of slots, one slot located between each pair of raised protrusions, said clamping system characterized in that the clamping system comprises at least one body ( 1 ), which is passed through by one of a cross bolt ( 7 ) or a cross screw ( 8 ), and wherein said one of said cross bolt ( 7 ) or said cross screw ( 8 ) have a stop bar ( 14 a or 14 b ), which engages in a cross slot ( 18 ) in said mounting rail when said clamping system is mounted to said mounting rail ( 10 ), characterized in that a hinge pin ( 24 ) is divided into a small cylindrical segment ( 36 ), a square ( 37 ) and a large cylindrical segment ( 38 ), and wherein a diameter of the small cylindrical segment is equal to or less than a diameter of the large cylindrical segment.

12. The clamping system of claim 11 , wherein said mounting rail is a Picatinny-rail.
