Abstract
The invention relates to a novel locking assembly including a readily removable handle arrangement that can be quickly and easily interchanged with any number of other handles having whatever configuration is desired. This is accomplished by introducing an adaptor between the conventional locking mechanism and the handle that facilitates the rapid interchange. Specifically, the adaptor includes the key core and defines an outer end surface having a raised portion of an elliptical shape and a corresponding handle that has an end opening that conforms to the elliptical shape and when in place is secured to the adaptor.
Claims2
A removable handle assembly for a door locking assembly that includes a locking mechanism that when operated retracts a door latch, a rose and base assembly fitting over an opening in the door, an adaptor fitting within an opening defined by the rose and base assembly, the adaptor containing a cylinder core and a throw member that extends from the cylinder core through aligned openings in the rose and base assembly that interconnects the cylinder core with the locking mechanism, the outer portion of the adaptor defining a planar portion and a raised portion having an oval configuration, a handle defining an opening extending therethrough having the same configuration as said raised portion and defining a surface disposed against said planar portion, and at least one fastener extending through the planar portion and being received by the handle when the handle is in position with its opening receiving the raised portion of said adaptor with the planar portion of the adaptor in abutting relationship with said handle surface whereby the handle can be interchanged and maintained in positive engagement with said adaptor whenever desired by merely disengaging the handle from the adaptor and replacing it with a different handle that defines an opening corresponding to the raised portion of said adaptor.
