Abstract
A mechanical magnetic key operated door lock structure particularly adapted for use in hotel locksets. An occupancy indicator is incorporated in the lock structure to indicate that the lockset is locked from the inside, thus insuring privacy for the hotel guest. In addition, means operable from outside the lock structure is provided for changing the combination of the lock so that a newly arriving guest may be provided with a key having a different combination from that used by the previous guest.
Claims20
In a magnetic key actuated lock structure that includes a housing, a slidable core in said housing adapted to be translated from a locking position to an unlocking position by a magnetically coded key and a locking plate alongside said core provided with apertures for receiving locking pins therein from said core, the improvement that comprises:
- a locking pin carrier carried by said core and slidably supporting a code changing locking pin therein,
- a tool operable from outside said housing for moving said carrier and said code changing pin relative to said core for changing the code of said lock structure.
In a magnetic key operated lockset, an occupancy indicator structure therefor, including a housing, said housing including a tail piece, a slidable core containing locking elements, and a pair of plates between which a magnetic key may be inserted, the improvement that comprises:
- first and second pins slidable axially of said structure,
- said core being formed with an opening receiving said first pin therethrough,
- said first pin being operatively connected to said tail piece for axial movement of said first pin upon depression of said tailpiece,
- means mounting said second pin for axial movement in response to said axial movement of said first pin,
- said housing having an outer wall adapted to receive one end of said second pin therethrough upon depression of said tail piece,
- one of said plates being provided with an opening for receiving said first pin therethrough for blocking the entry of such magnetic key when said tail piece is depressed.
A magnetic key for use with a magnetic key operated lockset which includes an occupancy indicator structure having an axially movable pin:
- said key being formed with an opening for receiving said pin therethrough,
- said key being formed in a plurality of separable parts for insertion seriatim in such lockset.
In a magnetic key operated lockset,
- an occupancy indicator structure including an axially moveable pin,
- a magnetic key for operating said lockset,
- said key being formed with an opening for receiving said pin therethrough.
In a magnetic key operated lockset having a housing, said housing including a tail piece, a slidable core containing locking elements, and a pair of plates between which a magnetic key may be inserted, a lockout structure for said lockset comprising:
- a pin slidable axially of said housing,
- said core being formed with an opening receiving said pin therethrough,
- said pin being operatively connected to said tail piece for axial movement of said pin to a position between said plates upon depression of said tail piece to thereby exclude such magnetic key.
