Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
137 words
A centrally monitored electric combination lock system for hotel doors and the like, comprising: combination selection board means including variable means for introducing a selected code into the system, means for recording said code, means for establishing a circuit upon the recording of said code, lock means operatively responsive to said established circuit, means for breaking said circuit while retaining the recorded code, said means for introducing the code being operable in accordance with the code to reestablish the circuit and being inoperative to reestablish the circuit if operated in any manner other than that of the selected code, means for operating said lock means independently of said established circuit, and means for monitoring and clearing the selected code from said system from a remote location so that the same or another selected code may be introduced.
Claim 2
Dependent Claim
137 words
A centrally monitored electric combination lock system for hotel doors and the like, comprising: combination selection board means including variable means for introducing a selected code into the system, means for recording said code, means for establishing a circuit upon the recording of said code, lock means operatively responsive to said established circuit, means for breaking said circuit while retaining the recorded code, said means for introducing the code being operable in accordance with the code to reestablish the circuit and being inoperative to reestablish the circuit if operated in any manner other than that of the selected code, means for operating said lock means independently of said established circuit, and means for monitoring and clearing the selected code from said system from a remote location so that the same or another selected code may be introduced.
Claim 3
Dependent Claim
110 words
A system as recited in claim 1, wherein the means for introducing a selected code comprises a keyboard having plural rows of key assemblies, and wherein the means for recording said code comprises a respective rack assembly movably mounted in said keyboard in alignment with each of said rows, each rack assembly having structure adapted for engagement, on movement of the rack, with a portion of a key assembly depressed in the respective row aligned with the rack, and with each rack assembly having structure offset from the first said structure and adapted for preventing depression of other key assemblies in said row subsequent to said movement of the rack.
Claim 4
Dependent Claim
58 words
A system as recited in claim 2 wherein each key assembly comprises: a depressable key, a key stem in spaced relation with the key, spring means for urging the key stem towards the key, and spring means stronger than the first said spring means for urging the key stem away from the key on depression of the key.
Claim 5
Dependent Claim
38 words
A system as recited in claim 3, wherein the means for recording said code includes solenoid means for moving the respective racks, and contact means responsive to depression of the respective key stems for actuating said solenoid means.
Claim 6
Dependent Claim
27 words
A system as recited in claim 4, wherein each said key is adapted for actuation of a key stem in plural of said rows of key assemblies.
Claim 7
Dependent Claim
40 words
A system as recited in claim 4, wherein the means for recording said code includes a magnetic release latch adapted for engaging all said racks on said movement thereof by the solenoid means, thereby preventing retraction of said moved racks.
Claim 8
Dependent Claim
65 words
A system as recited in claim 4, wherein the means for establishing a circuit comprises spring switch means responsive to depression of each said key stem, plural circuit means respectively common to the spring switch means in each row of key assemblies, and relay means connected with the plural circuit means and adapted for establishing serial portions of said circuit corresponding to said recorded code.
Claim 9
Dependent Claim
40 words
A system as recited in claim 7, wherein said means for breaking said circuit includes switch means operated by opening said door, and a code cancelling circuit responsive to said switch means and adapted to release a said relay means.
Claim 10
Dependent Claim
19 words
A system as recited in claim 8 wherein said means for breaking the circuit includes a manually operable switch.
Claim 11
Dependent Claim
57 words
A system as recited in claim 9 wherein all said circuits, circuit means, and solenoids are operated on direct current, and wherein the direct current is supplied through a reversible switch at said central location, whereby reversal of said reversible switch releases said magnetic release latch and retracts all said solenoids and racks, thereby clearing said system.
Claim 12
Dependent Claim
82 words
A system as recited in claim 8, iNcluding an alarm circuit actuated by the door switch means for signaling at said remote location on opening of said door, and a second switch means actuated by opening said door, the second switch means adapted to open said alarm circuit in response to establishment of said circuit corresponding to the code, thereby preventing the alarm from sounding when the door is opened after actuation of the lock means through said combination selection board means.
Claim 13
Dependent Claim
23 words
A system as recited in claim 11, and a heat detector operatively connected through said alarm circuit for signaling at said remote location.
Claim 14
Dependent Claim
37 words
A system as recited in claim 12, and an electric key switch adapted to bypass all said means for establishing a circuit corresponding to said recorded code and said alarm circuit, and to actuate said lock means.
Claim 15
Dependent Claim
83 words
A system as recited in claim 7 wherein said relay means includes a time delay relay means activated by depression of an initial key in establishing said circuit corresponding to said recorded code, and deactivated by depression of a last key in establishing said circuit within the time of said delay, said time delay relay means being adapted to interrupt the establishment of said circuit corresponding to said recorded code on expiration of said delay time prior to depression of said last key.
