Description
113981~7 Bac~ground of the In~ention _ .
The present invention relates generally to card storage and ~iewing equip~ent, and specifically concerns a device for storing index or file cards. The device of the present invention has the general appearance of ordinary devices for storing index or file cards when it is closed. Such devices are well known in the prior art and ordinarily consist of a box-shaped container having an open top and a lid hingeably connected to the container to close the top. The cards are inserted into the container so that the top of the cards can be seen when the lid is opened. This design has several distinct disadvantages.
It is difficult to view more than the upper portion of each card. Additionally, there is no room to insert one's fingers for the purpose of flipping through the cards or to remove an individual card from the box. The arrangement is particularly cumbersome when the box is full or nearly so.
A container which elevates a stack of index cards for display purposes is described in U.S. Patent ~o.
4,091,918, which issued to G. Soulakis and C. Mandala on May 30, 1978. The device of that patent comprises a carrier which fits into a box containing the cards and on which the cards rest. When the lid of the box is opened, the carrier is lifted up and back towards the rear of the - box. At the same time, a plate which is hingedly connec-ted to the carrier and fixedly connected to the front of the box moves rom it~ upright position to an angular position with respect to the carrier. When the lid is fully opened, the carrier is at an angle with respect to the horizontal - its rear end being higher than its front end. Tn this position, the plate serves as a stop against which the cards may rest when they are flipped forward.
However, this device is somewhat cumbersome and relatively expensive and difficult to manufacture as compared to many of the prior art card storage devices.
The device of the present invention obviates the disadvantages of the prior art, and particularly the disadvant-ages of the device illustrated in U.S. Patent 4,091,918.
It is an object of the present invention to provide a card file which allows the cards to be easily viewed while being retained within the device.
It is a further object of the invention to provide a card file which allows an individual card to be easily removed from and then reinserted into the device.
It is a still further object of the present invention to provide a card file which is lightweight and easy to assemble.
Summary of the Invention In a first aspect of the invention, there is provided an improved construction of 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 rigid therefrom. The improvement comprises a rear wall mounted near the bottom wall of the compartment for rearward pivotal movement away from the vertically extending walls of the compartment, cover means mounted to at least one of the verti-cally extending walls for rearward pivotal movement from a closed position in which the cover substantially covers the upper most ends of the vertically extending walls, the cover means having a depending member at its rear, and travel circumscribing means disposed in a fixed position on the depending member of the cover means and contacting the rear wall for limiting the rearward travel of the rear wall, the travel circumscribing means maintaining the rear wall in an 11398~7 upright position when the cover means is in the closed position, but permitting increased rearward pivoting of the rear wall as the cover is pivoted away from the closed position.
In preferred embodiments of the aforesaid first aspect of the invention, the rear wall may advantageously be pivotally mounted to the side walls of the compartment and may include a pair of pins projecting laterally outwardly from the rear wall adjacent to the bottom edge thereof, the pins being positioned within corresponding cavities in the side walls of the compartment, so as to permit the rear wall to pivot rear-wardly with respect to the front wall of the compartment.
Further, the improved construction of index or file card storage device provided in the first aspect of the invention may advantageously include stopping means on the rear wall to prevent it from moving forwardly with respect to the front wall of the compartment when the cover means are in a closed position. The stopping means employed may comprise protuber-ances on the rear wall which extend laterally past the edges of the side walls of the compartment.
In a further embodiment of the aforesaid first aspect of the invention, the cover means mounted to at least one of vertically extending walls of the compartment comprises a top wall with a rear wall, a pair of side walls and a front wall extending vertically and rigidly therefrom, the side walls of the cover means being pivotally mounted to the side walls of the aompartment and extending over a portion of the compartment side walls, the front wall of the cover means extending over a portion of the front wall of the compartment and the rear wall of the cover means extending over a portion of the compartment - -3a-113~3~17 rear wall when the cover means is in a closed position, in order to maintain the pivotally mounted compartment rear wall in an upright or vertical position when the cover means is closed. Advantageously, the cover means rear wall may engage another portion of the rear wall of the compartment when the cover means is in an opened position in order to limit the rearward travel of the pivotally mounted compartment rear wall when the cover means is opened.
In a second aspect of the present invention there is provided a container fbr storing flat objects in a substantially vertical position, the 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 the bottom wall for pivotal movement with respect to the compart-ment, the rear wall closing the open back of the compartment when in a substantially vertical position, a cover mounted to the compartment at a pivot point near the open back for pivotal movement with respect to the compartment, the cover pivoting rearwardly from a closed position in which its open top is substantially covered to an open position in which its open top is exposed, the cover means having a depending member at its rear, and a travel circumscribing portion dis-posed in fixed position on the depending member of the cover substantially in the plane of the open back of the compartment when the cover is in its closed position and intermediate the pivot point and the top of the cover, the travel circum-scribing portion being in continuous contact with the rear wall under normal operation, whereby the rear wall is retained in a substantially vertical position when the cover is in its -3b-113~817 closed position and is progressively rearwardly inclined as the cover is pivoted to its open position.
In the improved container constructed according to the aforesaid second aspect of the invention, it is preferred that the travel circumscribing means pivot the rear wall forwardly with respect to the compartment front wall as the cover is closed until the compartment rear wall reaches a vertical or upright position corresponding to the closed postion of the cover.

Detailed Descri tion of the Preferred Embodiment P
Referring now to the detailed drawings, the invention is directed to a construction for a contai~er 10 for storing index cards 30. Compartment 18 of container 10 has a front wall 40, two side walls 42 and 44, and a bottom wall 46. Wall 20 is pivotally mounted to compart-ment 18 and forms the rear wall of the compartment. In addition, container 10 includes a cover 12 which is also hingedly mounted to compartment 18.
Wall 20 includes pivot pin 26 and stop 28 on at least one side and preferably on two opposing sides of the wall. Pivot pin 26 extends outwardly along a bottom edge of wall 20 and protrudes past the periphery of the wall along a side edge. Pin 26 is preferably dowel-shaped and ; fits into holes 26a in sidewalls 42 and 44, as will be ex-plained more fully below. Any suitable means may be used to pivot wall 20 with respect to side walls 42 and 44.
Stop 28 consists of an outward projection of the periphery of wall 20 along a side edge, which may be the same side edge past which pin 26 protrudes. It is only necessary for stop 28 to be positioned along one side edge of wall 20 in order for it to serve its intended purpose, but additional stops may be used for the sake of uniform-ity or ease of manufacture.
Cover 12 is made up of cover top 32, side walls 36 which extends downwardly from the cover top, a front ~ ., ~ ~ , . . .
~139Eli7 1 wall 38 and at back wall 34 which form a closed perimeter for the cover. Thus, in the preferred embodiment, cover top 32 is rectangular in shape and walls 34, 36 and 38 extend downwardly therefrom. Cover 12 includes a hole 14a in each of the side walls 36 and an indentation (not shown) on the interior-facing side of front wall 40.
In the preferred embodiment bottom wall 46 is rectangular in shape and three side walls extend upwardly therefrom to form compartment 18. The surface area of bottom wall 48 is slightly smaller than the surface area of cover top 32 so that the cover top 32 can close over the compartment 18.
Each compartment side wall 42 and 44 has a pivot hole 26a located near the lower corner of the wall adjacent the open side. In addition, a hinge pin 14 extends outwardly from the exterior surface of each of the compartments side walls 42 and 44. An indentation 28A is formed along the periphery of each of the side walls 42 and 44 adjacent the open side of the compartment for the purpose of cooperating with corresponding stops 28 on wall 20.
In use, the pivot pins 26 which protrude past the periphery of wall 20 fit into pivot holes 26a in each of the compartment side walls 42 and 44. Stops 28 on wall 20 are aligned with the indentations 28A along the periphery of each of the compartment side walls. These stops prevent wall 20 from falling forwardly into the interior of compartment 18 while allowing container 10 to be closed tightly.
The hinge pins 14 on each of the compartment side walls 42 and 44 fit into holes 14a on each of the cover side walls 36. When cover 12 is closed, the indentation on the interior surface of front wall 38 fits over the protru-sion on compartment front wall 40, locking the cover in a closed position. This retains wall 20 in an upright position and maintains the compartment in a tightly closed position.
, 11398~7 1 When cover 12 is opened, wall 20 pivots backwardly, permitting cards 30 to fan out. As illustrated in Fig. 3, when card file 10 is on a flat surface, travel circumscribing wall 34 limits the backward pivotal movement of wall 20 to some predefined maximum rotation determined by the length of wall 34.
Although the invention has been described in terms of a specific embodiment, it will be appreciated by one skilled in the art that other embodiments in accordance with the present invention may be used. For example, the posi-tions of pivoting wall 20 and compartment front wall 40 could be reversed. The compartment would lock in the same manner as has already been described, but the cards would fan for-wardly when cover 12 was opened. Also,--the compartment rear wall and the cover could be pivotally mounted to the bottom wall of the compartment rather than to the compartment side walls. It will also be appreciated that the card file of this invention may be made of any suitable material such as plastic, metal, wood or the like and may be made in any suit-able size. What is claimed as new and desired to be madethe subject of Letters Patent is set out in the accompanying claims.
