Abstract
Abstract A media protection system 10 uses a media storage box 20 arranged within a fire resistant safe 11 so that the media box door 25 and the safe door 12 cooperate to seal media box 20 closed and hold it spaced from interior walls of safe 11. Media box door 25 has a roller 30 arranged on a pivot axis 26 spaced forward and below its hinge axis 24 at the lower front of media box 20. The weight of media box 20 and its door 25 resting on door roller 30, which can roll along a horizontal surface of the interior 14 of safe 11, automatically biases safe door 12 to either a fully closed position or a fully open position. An abutment 35 on the inside of safe door 12 presses media box door 25 fully closed and sealed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
258 words
A media protection system including a media storage box arranged within a fire resistant safe and comprising: a. said media box, in a rest position, being spaced from interior walls of said safe and having a front opening oriented toward a door of said safe; b. said media box having a door for said front opening; c. a hinge joining said media box door to a lower front region of said media box where said hinge has a pivot axis; d. a roller arranged on a bottom region of said door so that said roller has an axis spaced forward and below said hinge axis when said media box door is closed; e. said roller being arranged for supporting the weight of a front region of said media box and said media door above a horizontal surface within said safe along which said roller rolls as said media door opens and closes; f. said roller and said media door being arranged so that from a half-closed to a closed position of said media door, said roller axis is forward of said hinge axis so that the weight of said media door and said media box resting on said roller urges said door closed; and g. said roller and said media door being arranged so that from a nearly open to a fully open position of said media door, said roller axis is behind said hinge axis so that the weight of said media door and said media box resting on said roller urges said media door fully open.
Claim 2
Dependent Claim
258 words
A media protection system including a media storage box arranged within a fire resistant safe and comprising: a. said media box, in a rest position, being spaced from interior walls of said safe and having a front opening oriented toward a door of said safe; b. said media box having a door for said front opening; c. a hinge joining said media box door to a lower front region of said media box where said hinge has a pivot axis; d. a roller arranged on a bottom region of said door so that said roller has an axis spaced forward and below said hinge axis when said media box door is closed; e. said roller being arranged for supporting the weight of a front region of said media box and said media door above a horizontal surface within said safe along which said roller rolls as said media door opens and closes; f. said roller and said media door being arranged so that from a half-closed to a closed position of said media door, said roller axis is forward of said hinge axis so that the weight of said media door and said media box resting on said roller urges said door closed; and g. said roller and said media door being arranged so that from a nearly open to a fully open position of said media door, said roller axis is behind said hinge axis so that the weight of said media door and said media box resting on said roller urges said media door fully open.
Claim 3
Dependent Claim
66 words
The system of claim 1 including a downwardly oriented pivot hook arranged along an upper rear region of said media box and an upwardly oriented pivot hook arranged on an inside surface of a rear region of said safe so that said pivot hooks engage to support a rear region of said media box in said rest position clear of said interior walls of said safe.
Claim 4
Dependent Claim
30 words

Claim 10
Dependent Claim
48 words
The system of claim 7 including an inward facing abutment on said safe door arranged so that when said safe door is closed, said abutment engages and presses an upper front edge of said media box door tightly closed and holds said media box in said rest position.
Claim 11
Dependent Claim
15 words
The system of claim 9 wherein said abutment is formed of resilient and compressible material.
Claim 12
Dependent Claim
30 words
The system of claim 10 including a guard arranged to keep said pivot hooks from unhooking unless said media box moves forward from said rest position toward said safe door.
