Abstract
Abstract A cassette holder has multiple compartments; each compartment has a leaf spring for urging a cassette into one or the other of two stable positions. The first stable position, a cassette stored position, has the spring bearing on top of a cassette and forcing the cassette tightly against the bottom of a compartment. The second position, a cassette removal position, has the spring bearing against the upper back wall of a cassette to maintain the cassette canted with an upper corner protruding from the compartment for ease of grasping by a user. A pivot at the junction of a pocket and an upper section of the back wall of each compartment rotates a cassette to the removal position upon the application of finger pressure on the bottom of the cassette. A second pivot in the form of a foot at the entrance of each cassette causes the cassettes to pivot out of the compartment on being pulled and prevents a cassette from being pulled directly out of a compartment. Interlocking tenon and mortises permits modular buildup of several holders.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
150 words
A holder for tape cassettes comprising: (a) a plurality of side-by-side compartments, each for receiving and storing a tape cassette, each compartment having an entrance; (b) pivot means in each compartment for engaging the tape cassette; (c) spring means in each compartment for bearing against a wall of the cassette and urging the cassette against the holder while the cassette is in a stored position and for bearing on the back of the cassette to urge the cassette outwardly of the compartment in an alternate, partially withdrawn position, the wall being different from the back, the spring means and the pivot means cooperating to aid in effecting canting of the cassestte from the stored position to the partially withdrawn position upon the application of a force on the cassette by a user of the holder that cants the cassette outwardly with a corner of the cassette free of the compartment.
Claim 2
Dependent Claim
150 words
A holder for tape cassettes comprising: (a) a plurality of side-by-side compartments, each for receiving and storing a tape cassette, each compartment having an entrance; (b) pivot means in each compartment for engaging the tape cassette; (c) spring means in each compartment for bearing against a wall of the cassette and urging the cassette against the holder while the cassette is in a stored position and for bearing on the back of the cassette to urge the cassette outwardly of the compartment in an alternate, partially withdrawn position, the wall being different from the back, the spring means and the pivot means cooperating to aid in effecting canting of the cassestte from the stored position to the partially withdrawn position upon the application of a force on the cassette by a user of the holder that cants the cassette outwardly with a corner of the cassette free of the compartment.
Claim 3
Dependent Claim
55 words
The holder claimed in claim 1 wherein the spring means comprises a leaf spring at the top of each compartment positioned to bear on the top of a cassette in the cassette stored position, and against the back of the cassette in the cassette partially withdrawn position, the top of the cassette being the wall.
Claim 4
Dependent Claim
30 words
The holder claimed in claim 1 including an upstanding step at the entrance to each compartment, the step preventing the bottom of a cassette from translating out of the compartment.
Claim 5
Dependent Claim
136 words
The holder claimed in claim 1 wherein each compartment has a back wall, a floor, a roof, and an interior barrier between the compartment and an adjacent one of the compartments, the barrier comprising a bottom barrier extending from the entrance to the back of the compartment and upwardly from the floor to a termination well below the roof, a back barrier extending partially from the back wall of the compartment towards the entrance, and an upper barrier extending from the back wall and roof towards the entrance, the bottom barrier being for guiding a cassette into and out of the compartment, the rear barrier presenting sideways constraint to a cassette along its length, and the upper barrier presenting a constraint to the top of the cassette when it is in the alternate, partially withdrawn position.
Claim 6
Dependent Claim
42 words
The holder claimed in claim 4 wherein the spring means comprises a leaf spring at the top of each compartment positioned to bear on the top of a cassette in the cassette stored position, the top of the cassette being the wall.
Claim 7
Dependent Claim

The holder claimed in claim 5 including an upstanding step at the entrance to each compartment, the step preventing the bottom of a cassette from translating out of the compartment.
Claim 8
Dependent Claim
91 words
The holder claimed in claim 1 wherein each compartment has a pocket in its back wall towards the bottom of the compartment to provide clearance for a cassette during and the pivot means is located adjacent the pocket and above the bottom of the compartment to engage a cassette and effect its canting upon the application of the force by the user pushing inwardly along a line below the pivot means, the back wall of the compartment having a section extending above the pocket and joining the pocket at a junction.
Claim 9
Dependent Claim
