Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
131 words
A security storage apparatus for protecting magnetic tapes, disks and similar articles from inadvertent damage, sabotage or unauthorized use comprising a storage enclosure having an access formed therein and opening into a storage space therein for enclosing the articles, a closure for sealing said access and selectively operable for opening said access to expose said storage space, restrictor means normally in condition to engage said closure for limiting operation thereof and operable to a condition to prevent engagement thereof with said closure to allow full operation of said closure, actuator means associated with said restrictor means and normally responsive to the limited operation of said closure under the normal conditions of said restrictor means to operate said restrictor means, and restrictor control means operable to prevent operation of said restrictor means.
Claim 2
Dependent Claim
131 words
A security storage apparatus for protecting magnetic tapes, disks and similar articles from inadvertent damage, sabotage or unauthorized use comprising a storage enclosure having an access formed therein and opening into a storage space therein for enclosing the articles, a closure for sealing said access and selectively operable for opening said access to expose said storage space, restrictor means normally in condition to engage said closure for limiting operation thereof and operable to a condition to prevent engagement thereof with said closure to allow full operation of said closure, actuator means associated with said restrictor means and normally responsive to the limited operation of said closure under the normal conditions of said restrictor means to operate said restrictor means, and restrictor control means operable to prevent operation of said restrictor means.
Claim 3
Dependent Claim
42 words
A security storage apparatus as defined in claim 1 wherein said storage enclosure has multiple accesses therein, and said closure comprises multiple sliding doors for sealing said accesses and individually operable for selectively opening said accesses to selectively expose said storage space.
Claim 4
Dependent Claim
18 words
A security storage apparatus as defined in claim 2 wherein said storage enclosure space comprises multiple storage cells.
Claim 5
Dependent Claim
74 words
A security storage apparatus as defined in claim 1 wherein said restrictor means comprises solenoid means having plunger means normally urged by gravity into the condition for engaging said closure for limiting movement thereof and being electrically operable to the condition for preventing engagement thereof by said closure, and said actuator means comprises an electrical power circuit having an operating switch responsive to the limited movement of said closure to actuate said restrictor means.
Claim 6
Dependent Claim
29 words
A security storage apparatus as defined in claim 4 wherein said restrictor control comprises a control switch in said restrictor electrical power circuit and in series with said restrictor.
Claim 7
Dependent Claim
36 words
A security storage apparatus as defined in claim 1 wherein said restrictor control means comprises a master control means operable in response to a magnetic force field of predetermined intensity with respect to said storage space.
Claim 8
Dependent Claim
89 words
A security Storage apparatus as defined in claim 3 wherein said storage enclosure comprises a cabinet with said multiple storage cells arranged as shelves therein, said restrictor means comprises solenoid means having plunger means normally urged by gravity into the condition for engaging said closure for limiting movement thereof and being electrically operable to the condition for preventing engagement thereof by said closure, and said actuator means comprises an electrical power circuit having an operating switch responsive to the limited movement of said closure to actuate said restrictor means.
Claim 9
Dependent Claim
36 words
A security storage apparatus as defined in claim 3 wherein said restrictor control means comprises a master control means operable in response to a magnetic force field of predetermined intensity with respect to said storage space.
Claim 10
Dependent Claim
44 words
A security storage apparatus as defined in claim 6 wherein said restrictor control means comprises a master control means operable in response to a magnetic force field of predetermined intensity with respect to said storage space to indicate the presence of said magnetic field.
Claim 11
Dependent Claim
43 words
A security storage apparatus as defined in claim 4 wherein said restrictor control means comprises a circuit breaker means in series with said solenoid means and operable in response to a predetermined current demand in said electrical power circuit to open said circuit.
Claim 12
Dependent Claim
30 words
A security storage apparatus as defined in claim 7 wherein said solenoid and plunger means comprises a solenoid and plunger associated with each of said sliding doors for engagement therewith.
Claim 13
Dependent Claim
38 words
