Abstract

Abstract In a storage receptacle for a magnetic tape cassette which comprises a housing having spaced apart, parallel side walls which, between their forward edges, define an opening of the housing, and a holder pivotally connected with the housing for swinging movement through such opening between an opened position in which the holder projects forwardly from the housing for receiving and relinquishing a cassette, and a closed position in which the holder cooperates with the housing for enclosing a cassette cradeled in the holder; the pivotal connection of the holder with the housing provides a fulcrum for the holder which is spaced rearwardly from the center of gravity of the holder with a cassette therein in all positions of the holder ranging from its closed position to its opened position so that the force of gravity urges the holder from its closed position to its opened position upon the release of a latch provided for releasably retaining the holder in its closed position.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 168 words
A storage receptacle for a magnetic tape cassette comprising: a housing including spaced apart, parallel side walls which, between their forward edges, define an opening of said housing; a holder for embracing a magnetic tape cassette and which is movable with the cassette carried by said holder through said opening of the housing between said side walls of the latter; and pivot means connecting said holder with said housing for swinging relative to the latter between an opened position in which said holder projects forwardly from said housing for receiving and relinquishing a cassette, and a closed position in which said holder cooperates with said housing for enclosing a cassette in said holder; said pivot means being spaced rearwardly from the center of gravity of said holder, calculated with a cassette therein, in all positions of said holder ranging from said closed position to said opened position so that the force of gravity urges said holder with a cassette therein from said closed position to said opened position.
Claim 2
Dependent Claim 168 words
A storage receptacle for a magnetic tape cassette comprising: a housing including spaced apart, parallel side walls which, between their forward edges, define an opening of said housing; a holder for embracing a magnetic tape cassette and which is movable with the cassette carried by said holder through said opening of the housing between said side walls of the latter; and pivot means connecting said holder with said housing for swinging relative to the latter between an opened position in which said holder projects forwardly from said housing for receiving and relinquishing a cassette, and a closed position in which said holder cooperates with said housing for enclosing a cassette in said holder; said pivot means being spaced rearwardly from the center of gravity of said holder, calculated with a cassette therein, in all positions of said holder ranging from said closed position to said opened position so that the force of gravity urges said holder with a cassette therein from said closed position to said opened position.
Claim 3
Dependent Claim 21 words
A storage receptacle according to claim 1; further comprising latch means for releasably securing said holder in said closed position thereof.
Claim 4
Dependent Claim 73 words
A storage receptacle according to claim 2; in which said latch means includes a resilient tongue which is depressible between said side walls of the housing at the top of the latter, and oppositely raked latch teeth on said tongue and at the top of said holder in said closed position, said latch teeth engaging each other in said closed position and being released from each other when said resilient tongue is depressed.
Claim 5
Dependent Claim 41 words
A storage receptacle according to claim 2; in which said holder has spaced apart side walls movable between said side walls of the housing, and said pivot means are provided at the adjacent side walls of said housing and holder, respectively.
