Abstract
A key ring which includes a metal ring with an open segment area for the insertion and removal of keys has the metal ring mounted in a circular guide groove of a handle portion such that the ring is rotatable therein. A latch is slidably disposed in a passage in the handle portion and spring-biased into engagement with the metal ring for locking the metal ring to prevent its rotation. Means are provided for disengaging the latch so as to permit rotation of the metal ring.
Claims7
A key ring comprising:
- a handle portion having a circular passage extending therethrough at least at one end;
- a metal ring rotatably disposed in said circular passage, said metal ring having an open segment area;
- a latch member movably supported in said handle portion;
- said handle portion having a narrow cavity and spring means having interconnected undulated sections arranged in spaced parallel relationship disposed and contained in said cavity for biasing said latch member toward said metal ring and into said open segment area when said open segment area is in the path of movement of said latch member for locking said ring in position;
- said latch member being movably supported in said handle portion in a passage which intersects, and extends normal to, said circular passage, and said latch member further having a portion extending at least to the surface of said handle portion at least at one side thereof so as to permit movement of said latch member out of engagement with said metal ring in order to allow rotation of the metal ring for removal and insertion of keys.

- a metal ring rotatably disposed in said circular passage, said metal ring having an open segment area;
- a latch member movably supported in said handle portion;
- said handle portion having a narrow cavity and spring means having interconnected undulated sections arranged in spaced parallel relationship disposed and contained in said cavity for biasing said latch member toward said metal ring and into said open segment area when said open segment area is in the path of movement of said latch member;
- the end faces of said metal ring defining said open segment area being inclined so as to define a wedge-formed open segment area of increased width at the radially outer end thereof, and said latch member being a body of circular cross-section forced into said open segment area by said spring means but displaceable therefrom by forceful rotation of said metal ring.
