Storage container
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The invention relates generally to a container for storing items such as floppy diskettes, compact audio disks, laser disks, phonograph records and the like which should be maintained in a dust-free environment. 
     Particularly, the invention is a lightweight, inexpensive container which has a door and slide arrangement whereby when the door is opened, the slide upon which the stored items rest is moved out of the container and the items which are stored within the container are deposited on the inner surface of the door in a staggered arrangement. The door is formed with a recessed portion on its inner surface which holds a reversible indexing stop member to stagger the items as they move out of the compartment in order to facilitate selection of the desired item from the group of items. The containers have the capability of storing a large number of items since each container may be connected to one or more identical containers to form a self-contained storage unit. 
     2. Description of the Prior Art 
     Storage cases are disclosed in U.S. Pat. Nos. 4,162,112; 4,339,162 and 4,270,817 but none of these patents discloses a container having a compartment closed by a door to protect items stored in the container from dust. This is extremely important because of the type of information which is stored upon diskettes or other items in the container. Additionally, many of the prior art containers utilize a separate mechanical mechanism such as a spring or a resilient member for biasing stored items out of the storage compartment, which adds to the initial expense of the storage case and to the likelihood of breakage due to continuous use. Typical of such arrangements are the storage cases disclosed in U.S. Pat. Nos. 4,162,112; 4,270,817 and 4,275,943. The container disclosed in U.S. Pat. No. 4,519,655 is a modification of the container disclosed and claimed herein without certain unloading features. 
     SUMMARY OF THE INVENTION 
     The invention is a container for storing disks and phonograph records and the like which includes a housing having a manually operated door which is pivotally connected to the bottom of the container housing and a movable slide located in the bottom of the housing which supports the items stored within the container and pivotally connected to the door. The pivotal connections are arranged so that when the door is rotated into the open position, the slide is moved partially out of the housing and is tilted toward a recessed portion on the inner surface of the door. The rear end of the slide is formed with an upstanding lip which contacts the rear edges of items which are resting on the upper surface of the slide base and pulls the items partially out of the housing when the door is opened. The recessed portion of the door supports a reversible indexing stop member having a plurality of steps to stagger the individual items as they are discharged from the housing to facilitate visual inspection and selection of the item or items desired by the user. The container is formed with spaced elongated feet on the exterior of the bottom which support the container in the upright position and which may be interlocked with raised channel members on the exterior of the top of another identical container so that the containers may be stacked and interlocked to form a vertical storage unit. Additionally, the exterior of one sidewall of the container is formed with angled channel members which cooperate with angled channel members formed on the exterior of the opposite sidewall of another identical container so that adjacent containers may be interlocked in a row to form a horizontal storage unit. As the disk and/or record library expands, additional containers may be easily and quickly locked into place to enlarge the capacity of the storage unit.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference to FIGS. 1-4 of the drawings, the container consists of a housing 1 and a door 2. The housing has a pair of spaced substantially parallel sidewalls 3, a multi-part bottom wall 4, a top wall 5, a rear wall 6 and an open front. The side, top and back walls and a portion of the bottom wall of the housing are integral and may be injection molded from a rigid fireproof thermoplastic polymer such as polystyrene, acrylonitrile-butadienestyrene (ABS) copolymer, polymethyl methacrylate, polycarbonate or polyethylene terephthalate and the like which can be either transparent or opaque. 
     As shown in FIGS. 3 and 4 of the drawings, the bottom wall 4 of the housing is formed by a rear part 7 which is integral with the rear wall 6 and the sidewalls 3. The rear part 7 has a slotted portion 8 at its forward end. The forward part 9 of bottom wall 4 has a tongue 10 at its rear end which fits into the slot in slotted portion 8 of rear part 7. The forward part 9 is sufficiently flexible so that the front end of the forward part can move vertically relative to housing 1. As seen in FIG. 4 of the drawings, the forward part 9 has a slight upward angle when the door 2 is in the open position for a purpose to be described hereinafter. An inwardly extending elongated foot 13 is located at the lower edge of each sidewall 3. The inwardly extending feet 13 support the container and also function as slides to cooperate with channels 12 molded on the outer surface of the top wall 5 of the housing. This slide and channel arrangement makes it possible to interlock two cases in a vertical stack as shown in FIG. 1 of the drawings. 
     The exterior surface of one sidewall of the housing is formed with an elongated horizontally extending angled channel member 14 adjacent to its upper edge and an elongated horizontally extending angled channel member 15 adjacent to its lower edge as shown in FIGS. 1 and 2 of the drawings. A pair of complementary angled channel members 16 and 17 are molded on the outer surface of the sidewall opposite the sidewall having members 14 and 15. The angles of members 14 and 16 are complementary as are the angles of members 15 and 17 so that member 14 will interlock with a member 16, and member 15 will interlock with a member 17 to connect two containers in a horizontal row as shown in FIG. 1 of the drawings. 
     The door 2 is pivotally attached to the front end of the forward part 9 of the bottom wall 4 by pivot pins 11. Each pin extends through a hole in the side web 25 of the door 2. As will be seen in FIGS. 3 and 4 of the drawings, the lower end 20 of the door 2 is located below the pivot pins 11 and contacts the front end of the lower surface of the forward part 9 of the bottom wall 4 to stop rotation of the door when the door is rotated into the open position. The upper end of the door is formed with an inset portion 21 which is adapted to be engaged by the user&#39;s finger and with a horizontal stop groove 22. Stop groove 22 fits within the upper forward end of the housing and is close to the inner surface of top wall 5 of the housing. The stop groove frictionally engages a bead 23 located on the inner surface of the top wall 5 when door 2 is in the closed position as shown in FIG. 3 of the drawings. In order to open door 2, a downward force is applied to ledge 24 in inset portion 21 to spring the front end of the forward part 9 of the bottom wall 4 downwardly to release the stop groove 22 from the bead 23. The door may then be rotated into the open position shown in FIG. 4. 
     As can be seen in FIGS. 3 and 4 of the drawings, a slide 30 is supported above bottom wall 4 by a pair of spaced front legs 33 and a pair of spaced rear legs 34 and is pivotally attached to the lower end of door 2 above the pivot pins 11 by a pair of outwardly extending horizontal pivot lugs 18 which are located at the forward end of the slide. Each lug fits into a horizontal hole formed in one of the spaced side webs 25 which extend along the elongated edges of the door 2. An upstanding lip 31 is located along the rear edge of the base 32 of slide 30. The lip 31 contacts the items stored on the slide so that they move forwardly out of the housing along with the slide when the door 2 is rotated into the open position. The movement of slide 30 is caused by the relative location of the pivot pins 11 and lugs 18 on the door 2. The lower ends of the front legs 33 at the forward end of the slide acts as a pivot point when the door 2 is opened so that as door 2 nears the end of its opening arc, the slide is tilted upwardly which causes the items resting on the slide base 32 to move into the recess 27 in door 2. The slide has spaced upstanding sidewalls along the opposite edges of base 32 to retain items on the base. Each sidewall has a raised forward portion 35 and a lower rear portion 36 extending between forward portion 35 and the upstanding lip 31. While not shown in the drawings, it will be understood by those skilled in the art that the upper surface of slide base 32 may be formed with a plurality of grooves for storing multiple items in spaced relationship. 
     As will be seen in FIG. 1 of the drawings, a reversible indexing stop member 40 is fitted within the recessed portion 27 on the inner surface of door 2. The indexing stop member has an outwardly extending horizontal tab 41 on each edge and the free end of each tab extends into a slot 43 in a web 25 of the door. The indexing stop member is formed with a plurality of steps 42 along one edge as shown in FIGS. 5 and 6. The indexing stop member 40 is held within the recessed portion 27 of door 2 so that it can be removed from the recessed portion, inverted and replaced in the recessed portion to change the steps from the position shown in FIG. 1 to the opposite hand position (not shown). The position of the indexing stop member in the recessed portion 27 will be determined by the location of the container relative to the user. When the closure member is opened, the base 32 of the slide is tilted upwardly about the bottom of front leg 33 and the items stored on the base move into the recessed portion 27 of door 2 until the forward edges contact the steps 42 on indexing stop member 40 so that the items come to rest in a staggered arrangement. The staggered arrangement makes it easy to select the desired item for subsequent use and exposes the edge of each item so that the items can be easily grasped by the user. 
     In operation, items are stored on the upper surface of the slide base 32 within the housing 1 of the container and the door 2 is in the closed position shown in FIG. 3 of the drawings. When door 2 is rotated into the open position shown in FIG. 4 of the drawings, the relationship between pivot pins 11 and the pivot lugs 18 permits the door 2 to open and at the same time pull slide 30 and the items resting thereon forward out of the housing of the container so that the front end of the slide is located outwardly of the housing 1. At the same time the slide tilts about the lower end of legs 33 so that the stored items resting on the base 32 of slide 30 move into the recessed portion 27 of door 2 until the forward edge of each item contacts a step 42 on indexing stop member 40. The items come to rest in a staggered arrangement due to the steps 42 on the indexing stop member 40 and can be grasped by the user. 
     While the housing of the container is shown as rectangular in shape in elevation, it will be understood by those skilled in the art that it can be square or more elongated in either the horizontal or vertical dimension depending upon the size and shape of the items to be stored therein. Also, the width of the storage compartment may be varied according to the thickness of the items being stored. 
     The storage container of the invention has numerous applications such as the storage of floppy disks in any of the standard, mini or micro sizes, the storage of compact audio disks and laser disks and the like. Also, with appropriate dimensioning, the container may be used to store phonograph records. 
     While a preferred embodiment of the invention has been described herein, it is to be understood that the invention may be embodied within the scope of the appended claims.
