Claim 2

In an index or file card storage device of the type having a compartment including a bottom wall, two side walls and a front wall all extending vertically and rigidly therefrom, the improvement comprising: a rear wall mounted near said bottom wall for rearward pivotal movement away from said vertically extending walls; cover means mounted to at least one of said vertically extending walls for rearward pivotal movement from a closed position in which said cover substantially covers the uppermost ends of said vertically extending walls, said cover means having a depending member at its rear; and travel circumscribing means disposed in a fixed position on said depending member of said cover means and contacting said rear wall for limiting the rearward travel of said rear wall, said travel circumscribing means maintaining said rear wall in an upright position when said cover means is in said closed position but permitting increased rearward pivoting of said rear wall as said cover is pivoted away from said closed position.

Claim 3

The improvement recited in claim 1, said rear wall being pivotally mounted to said compartment side walls.

Claim 4

The improvement recited in claim 2, said rear wall including a pair of pins projecting laterally outwardly therefrom adjacent the bottom edge of said rear walls, said pins being positioned within corresponding cavities in said compartment side walls so as to permit said rear wall to pivot rearwardly with respect to said front wall.

Claim 5

The improvement recited in claims 2, 3 or 1 further comprising stopping means on said rear wall to prevent said rear wall from moving forwardly with respect to said front wall when said cover means are in a closed position.

Claim 6

The improvement recited in claim 4, said stopping means comprising protuberances on said rear wall extending laterally past the edges of said compartment side walls.

Claim 7

The improvement recited in claim 1, said cover means comprising a top wall with a rear wall, a pair of side walls and a front wall extending vertically and rigidly therefrom, said cover side walls being pivotally mounted to said compartment side walls and extending over a portion of said side walls, said cover front wall extending over a portion of the compartment front wall and said cover rear wall extending over a portion of said compartment rear wall when said cover is in a closed position in order to maintain said pivotally mounted compartment rear wall in an upright or vertical position when said cover is closed.

Claim 8

The improvement recited in claim 6, said cover rear wall engaging another portion of said compartment rear wall when said cover is in an opened position in order to limit the rearward travel of said pivotally mounted compartment rear wall when said cover is opened.

Claim 9

The improvement recited in claim 1, further comprising means for locking or maintaining said cover in a closed position.

Claim 10

The improvement recited in claim 8, said locking means comprising a protrusion on said compartment front wall outer surface and a corresponding indentation on said cover front wall inner surface such that a force is required to disengage said protrusion from said indentation.

Claim 11

A container for storing flat objects in a substantially vertical position, said container including a compartment having a bottom wall and an open top and back, but being otherwise closed, and further comprising: a rear wall mounted near said bottom wall for pivotal movement with respect to said compartment, said rear wall closing said open back when in a substantially vertical position; a cover mounted to said compartment at a pivot point near said open back for pivotal movement with respect to said compartment, said cover pivoting rearwardly from a closed position in which said open top is substantially covered to an open position in which said open top is exposed, said cover means having a depending member at its rear; and a travel circumscribing portion disposed in a fixed position on said depending member of said cover substantially in the plane of said open back when said cover is in its closed position and intermediate said pivot point and the top of said cover, said travel circumscribing portion being in continuous contact with said rear wall under normal operation, whereby said rear wall is retained in a substantially vertical position when said cover is in its closed position and is progressively rearwardly inclined as said cover is pivoted to its open position.

Claim 12

A container for storing flat objects in a substantially vertical position, said container including a compartment having a bottom wall and an open top and back, but being otherwise closed, and further comprising: a rear wall mounted near said bottom wall for pivotal movement with respect to said compartment, said rear wall closing said open back when in a substantially vertical position; a cover mounted to said compartment at a pivot point near said open back for pivotal movement with respect to said compartment, said cover pivoting rearwardly from a closed position in which said open top is substantially covered to an open position in which said open top is exposed, said cover means having a depending member at its rear; and a travel circumscribing portion disposed in a fixed position on said depending member of said cover substantially in the plane of said open back when said cover is in its closed position and intermediate said pivot point and the top of said cover, said travel circumscribing portion being in continuous contact with said rear wall under normal operation, whereby said rear wall is retained in a substantially vertical position when said cover is in its closed position and is progressively rearwardly inclined as said cover is pivoted to its open position.

Claim 13

The improvement recited in claim 10, said moving means comprising said cover rear wall which engages a portion of said compartment rear wall and pivots said rear wall forwardly with respect to the compartment front wall as the cover is closed until said compartment rear wall reaches a vertical or upright position which corresponds with said cover being in a closed position.
