Universal lock cylinder
View Patent ↗A lock assembly includes a universal core assembly, which provides multiple engagement features to permit the core assembly to be mounted into various lock housings. A torque blade or a spindle assembly is received within a rear segment of the lock core to engage one of the engagement members depending upon the desire lock within which the core is to be mounted.
1. A lock core assembly comprising:
a barrel which defines an axis; and
a plug mountable for rotation within said barrel for rotation around said axis relative said barrel, said plug comprising an rear segment recessed within said plug which defines a first plane parallel to a second plane, said first plane and said second plane transverse and offset along said axis, a first engagement member at least partially within said first plane and a second engagement member at least partially within said second plane, said first engagement member perpendicular to said second engagement member.
2. The lock cylinder assembly as recited in claim 1 , wherein said second engagement member comprises a stop that extends from a circular member defined at least partially around said axis, said circular member located at least partially within said second plane.
3. The lock cylinder assembly as recited in claim 2 , wherein said circular member defines an inner diameter and said stop extends from said circular member transverse to said axis to define at least a portion of an outer diameter.
4. The lock cylinder assembly as recited in claim 1 , wherein said plug defines a groove.
5. The lock cylinder assembly as recited in claim 4 , further comprising a torque blade comprising a female end engageable with said rear segment.
6. The lock cylinder assembly as recited in claim 1 , further comprising a spindle comprising a female end engageable with said rear segment.
7. The lock cylinder assembly as recited in claim 6 , further comprising opposed spindle cams within said female end.
8. A lock core assembly comprising:
a barrel which defines an axis;
a plug mountable for rotation within said barrel for rotation around said axis relative said barrel, said plug defining a groove and comprising a rear segment which defines a first plane parallel to a second plane, said first plane and said second plane transverse and offset along said axis, a first engagement member at least partially within said first plane and a second engagement member at least partially within said second plane, said first engagement member perpendicular to said second engagement member;
a torque blade comprising a female end engageable with said rear segment; and
a retainer mountable at least partially within said groove, said retainer axially retaining said torque blade to said rear segment.
9. The lock cylinder assembly as recited in claim 8 , wherein said retainer is frustum-conically shaped.
10. A lock assembly comprising:
a lock housing;
a barrel which defines an axis, said barrel mountable within said housing;
a plug mountable for rotation within said barrel for rotation around said axis relative said barrel, said plug comprising a male rear segment;
a torque blade comprising a female end engageable with said male rear segment; and
a retainer axially retaining said female end over said male rear segment.
11. A lock assembly comprising:
a lock housing;
a barrel which defines an axis, said barrel mountable within said housing;
a plug mountable for rotation within said barrel for rotation around said axis relative said barrel, said plug comprising a male rear segment recessed within said plug;
a torque blade comprising a female end engageable with said male rear segment; and
a retainer axially retaining said female end over said male rear segment.
12. The lock assembly as recited in claim 11 , wherein said male rear segment comprises a first engagement member perpendicular to a second engagement member.
13. The lock assembly as recited in claim 12 , wherein first engagement member is axially displaced from said second engagement member.
14. The lock assembly as recited in claim 11 , wherein said second engagement member extends from a circular member, said circular member defines an inner diameter and said second engagement member extends from said circular member transverse to said axis to define at least a portion of an outer diameter.
15. A lock assembly comprising:
a lock housing;
a barrel which defines an axis, said barrel mountable within said housing;
a plug mountable for rotation within said barrel for rotation around said axis relative said barrel, said plug comprising a male rear segment wherein said male end is recessed within said plug;
a torque blade comprising a female end engageable with said male rear segment; and
a retainer axially retaining said female end over said male rear segment and engaging a groove defined about said plug.
16. A lock assembly comprising:
a lock housing;
a barrel which defines an axis, said barrel mountable within said housing;
a plug mountable for rotation within said barrel for rotation around said axis relative said barrel, said plug comprising a male rear segment; and
a spindle comprising a female end with opposed cams engageable with said male rear segment, wherein said male rear segment is recessed within said plug.
17. The lock assembly as recited in claim 16 , wherein said retainer is a frustum-conically shaped retainer.
