초록 ▼

A revolver has a detent mechanism providing positive mechanical engagement between the cylinder yoke and the frame. A housing mounted on the frame has a spring biased plunger that transversely engages a pin. The pin projects from the housing and engages a recess on the yoke when the revolver cylinder is closed. The pin is biased into engagement with the recess by the plunger to maintain the revolver closed and the chambers of the cylinder in precise alignment with the barrel during firing. Manual force applied to the cylinder can overcome the biasing force and permit the revolver to be opened and closed.

1. A revolver, comprising: a frame;a yoke mounted on said frame and movable about a pivot axis between an open and a closed position, a recess being positioned within said yoke;a cylinder mounted on said yoke;a detent mechanism, comprising:a housing mounted on said frame adjacent to said yoke;a pin bore positioned within said housing, said pin bore extending longitudinally along a pin bore axis;a plunger cavity positioned within said housing and intersecting said pin bore, said plunger cavity extending longitudinally along a plunger cavity axis, said plunger cavity axis being oriented transversely to said pin bore axis;a pin having a tip, said pin being positioned within said pin bore and movable along said pin bore axis between a first position, wherein said tip projects from said housing and engages said recess when said yoke is in said closed position, and a second position, wherein said tip is within said housing;an action surface positioned on said pin, said action surface being oriented transversely to said pin bore axis;a plunger having an end, said plunger being positioned within said plunger cavity and movable along said plunger cavity axis;a spring positioned within said plunger cavity and biasing said end of said plunger into engagement with said action surface of said pin. 2. The revolver according to claim 1, wherein said plunger cavity comprises an open end terminating on a surface of said housing and a closed end terminating within said housing, said spring being positioned between said closed end and said plunger. 3. The revolver according to claim 2, wherein said open end faces said yoke when said yoke is in said closed position. 4. The revolver according to claim 1, wherein said pin bore axis is parallel to said pivot axis. 5. The revolver according to claim 1, wherein said tip comprises a conical surface. 6. The revolver according to claim 5, wherein said pin comprises an end oppositely disposed to said tip, said end comprising a conical surface. 7. The revolver according to claim 1, wherein said pin has a round cross section. 8. The revolver according to claim 1, wherein said action surface has an orientation angle relative to said pin bore axis from 30° to 60°. 9. The revolver according to claim 1, wherein said action surface has an orientation angle relative to said pin bore axis of 45°. 10. The revolver according to claim 1, wherein said pin comprises a cylindrical body. 11. The revolver according to claim 10, wherein said action surface comprises a surface of a notch formed in said cylindrical body. 12. The revolver according to claim 11, wherein said notch is V-shaped. 13. The revolver according to claim 1, wherein said plunger has a round cross section. 14. The revolver according to claim 1, wherein said plunger comprises a cylindrical body. 15. The revolver according to claim 1, wherein said end of said plunger comprises at least one surface oriented angularly with respect to said plunger cavity axis. 16. The revolver according to claim 15, wherein said at least one surface has an orientation angle relative to said plunger cavity axis from 30° to 60°. 17. The revolver according to claim 15, wherein said at least one surface has an orientation angle relative to said plunger cavity axis of 45°. 18. The revolver according to claim 1, wherein said end of said plunger comprises first and second surfaces oriented angularly with respect to said plunger cavity axis.
