Door lock status indicator
First Claim
1. A status indicator for a door lock of the type having a rotating member and a tail piece attaching to said rotating member so as to be rotated by said rotating member the status indicator which comprises:
- linking means operatively connected to said tail piece so as at least a first portion of said linking means is rotated by said tail piece in response to rotation of said rotating member and in response to rotation of at least said first portion of said linking means a second portion being capable of movement between a first position and a second position;
indicating means located on said door so as to be visible on said door, said indicating means operatively associated with said second portion of said linking means so as to be operated on by said second portion of said linking means, said indicating means for indicating a locked state of said door and an unlocked state of said door, said indicating means indicating said locked state in response to movement of said second portion of said linking means to one of said first or said second positions and said indicating means indicating said unlocked state of said door in response to movement of said second portion of said linking means to the other of said first or said second positions;
said linking means includes a rotational to translational moving means operatively interspaced between said tail piece and said indicator means so as to be rotated by said tail piece and in response to said rotating producing a translational movement, said indicator means in response to said translational movement moving between said first and said second positions;
said linking means includes a tail piece member operatively connected to said tail piece so as to be rotated by said tail piece in response to rotation of said rotating member;
said linking means further including a linking member having ends, the first of said ends of said linking member operatively connected to said tail piece member so as to be moved in an arcuate pathway in response to rotation of said tail piece member, the second of said ends of said linking member moving linearly in response to arcuate movement of said first end.

Abstract
A status indicator for a door lock which is capable of being activated by a tail piece of the door lock has a first linking member which is operatively attached to the tail piece so as to be rotated by the tail piece and a second linking member which attaches between the first linking member and the indicating member. The second linking member translates the rotational movement of the first linking member to translational movement so as to move the indicating member linearly. The indicating member is housed within a housing plate which is attached to the door by the door lock. The indicating member moves within the housing member in response to change of the lock from a locked to an unlocked status and indicates this change so as to indicate the status of the lock, whether it is locked or unlocked.
