Magnetically stabilized firearm sight
A sight mechanism for firearms such as pistols, rifles and the like. The sight mechanism includes a sight member that has a rear sight that is vertically adjusted. The sight member can be mounted on a vertically moveable member that has a fixing member that sets the vertical position of the sight member. The vertically moveable member may, without limitation, be a pivoting member. The sight mechanism includes magnets that bias the vertical member against the fixing member so that the magnets maintain the sight at the vertical position defined by the fixing member.
1. A sight assembly for a firearm comprising:
a mounting assembly that is adapted to be attached to a firearm in a fixable relationship with respect to the barrel of the firearm;
a swing member that is pivotally attached to the mounting assembly wherein the swing member defines a mounting location;
a plate having a sighting aperture formed therein mounted on the mounting location of the swing member, wherein a vertical position of the plate is adjustable by pivoting of the swing member with respect to the mounting assembly; and
a magnetic biasing component that urges the swing member away from the mounting assembly to maintain the plate at a desired vertical location.
2. The sight assembly of claim 1 wherein the mounting assembly comprises a mounting plate that is sized to be positioned within a groove formed in a slide of a semiautomatic firearm.
3. The sight assembly of claim 2 , wherein the mounting plate includes two brackets and a pivot pin extending between the brackets and wherein the swing member includes an aperture that receives the pin so that the swing member is cantilevered with respect to the pivot pin.
4. The sight assembly of claim 1 , wherein the swing includes a vertical adjustment mechanism and a horizontal adjustment mechanism that adjusts the vertical and horizontal location of the aperture of the plate.
5. The sight assembly of claim 4 , wherein the horizontal adjustment mechanism comprises a screw that is attached to a member and the member defines a mounting location for the plate such that rotational movement of the screw results in translational movement of the plate.
6. The sight assembly of claim 1 , wherein a first member is positioned in the swing member that is adjustable to define a pivoting height of the swing member.
7. The sight assembly of claim 6 , wherein the first member comprises a screw that engages with the swing member and the mounting assembly.
8. The sight assembly of claim 6 , wherein the magnetic biasing component comprises magnets positioned so as to urge swing member to the pivoting height of the swing.
9. The sight assembly of claim 8 , wherein the magnets comprise a first and second set of opposed magnets mounted in the mounting assembly and the swing member.
10. The sight assembly of claim 1 , wherein the sighting aperture comprises a slot, an opening or a light projecting component.
11. A sight assembly for a firearm comprising:
a mounting assembly that is adapted to be attached to a firearm in a fixable relationship with respect to the barrel of the firearm;
a first movement member that is attached to the mounting assembly so as to be movable with respect thereto in a first direction wherein the first movement member defines a mounting location;
a sight mounted on the mounting location of the first movement member, wherein a first position of the sight is adjustable by movement of the first movement member with respect to the mounting assembly in the first direction; and
a magnetic biasing component that urges the first movement member away from the mounting assembly to maintain the sight at a desired first position.
12. The sight assembly of claim 11 , wherein the mounting assembly comprises a mounting plate that is sized to be positioned within a groove formed in a slide of a semiautomatic firearm.
13. The sight assembly of claim 12 , wherein the plate includes two brackets and a pivot pin extending between the brackets and wherein the first movement member is a vertical movement member and includes an aperture that receives the pin so that the vertical movement member is cantilevered and pivots with respect to the pivot pin.
14. The sight assembly of claim 13 , wherein a fixing member is positioned in the vertical movement member that is adjustable to define a pivoting height of the vertical movement member.
15. The sight assembly of claim 14 , wherein the fixing member comprises a screw that engages with the vertical movement member and the mounting assembly.
16. The sight assembly of claim 15 , wherein the magnetic biasing component comprises magnets positioned so as to urge vertical movement member to the pivoting height of the vertical movement member.
17. The sight assembly of claim 16 , wherein the magnets comprise a first and second set of opposed magnets mounted in the mounting assembly and the vertical movement member.
18. The sight assembly of claim 11 , wherein the sight comprises a slot, a closed opening or a light projecting component.
