ATTORNEYS I FICHE CLEANING ELEMENT CROSS-REFERENCE To RELATED APPLICATION The present invention is a division of pending application, Ser. No. l3,276,'filed Feb. 24, 1970 for Fiche Storage and Cleaning Apparatus now U.S. Pat. No. 3633761, issued Jan. ll, I972.

BACKGROUND F THE INVENTION SUMMARY OF THE INVENTION The present invention has overcome the shortcomings of the, prior art and provides a storage unit providing fast identification and retrieval of microfiche, and one which keeps the microfiche flat and clean. Particular features of the present invention are the construction and arrangement wherebylarge numbers of I microfiche can'be stored individuallyv within the unit in what is a relatively compact structure, adapted for future expansion. A limited number of components are required to fabricate the unit which can be made essentially of injection molded organic plastic parts.

According to one form of the present invention, a fiche storage unit is providedcomprising a plurality of trays stacked together to define a column of storage sections for storing fiche. A top cover member is secured on the upper member of the stack of trays and the cover member and the upper member of the stack define between them a horizontal slot of sufficient length for receiving one of the fiche. A push plate is positioned in the slot for limited movement between the members, and the push plate and one of the members have parallel ledges at their outer extremities on which cleaning elements are mounted for wiping a fiche that has been inserted between the push plate and one of the members. By virtue of this construction and arrangement a microfiche can be cleaned readily at any time that it may have become soiled. The cleaning elements are disposable strips that can readily be removed from the ledges on which they are mounted to be replaced by new cleaning elements when the need arises.

Thus, it is among the objects of the present invention to provide a cleaning element for use with a fiche storage unit which is constructed and arranged to store a large number of fiche in a relatively small structure, and which is arranged to keep the fiche flat and clean.

Other objects of this invention will appear in the following description ,and appended claims, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

1 DESCRIPTION OF THE PREFERRED EMBODIMENT Before explaining the present invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also, it is to be understood that the phraseology or terminology employed herein is. for the purpose of description and not of limitation.

Referring now to the drawings, the invention will be described in greater detail. The fiche storage unit 10 includes a turntable base 12 on which is mounted the column 14 of storage sections for storing fiche (not shown), and a top cover assembly 16 is mounted on the top of the column 14.

The top cover assembly 16 comprises the top cover member 18, the push plate 20, and the compression spring 22 which is positioned between the pushbutton 24 of push plate 20 and the upper member or tray 26 of the column14 for urging the push plate 20 upward to the position shown in FIG. 2, wherein the flange 28 of push plate 20 is seated against the undersurface 30 of the top cover member 18.

The upper member or tray 26 is one of the plurality of trays that will be described hereinafter which form the column 14, and it has ledges 32- projecting outwardly from two of the opposite sides of the tray or upper member 26. The top cover member 18 is secured to the upper member or tray 26 and is recessed at its opposite sides so as to define with the upper member 26 the horizontal slots 34 through which the ledges 36 of the push plate 20 project in parallel relationship to the ledges 32 of the upper member 26. Accordingly, the compression spring 22 will urge the parallel ledges 32 and 36 apart, and they can be moved together against the spring action by depressing the push button 24 which projects upwardly through the opening 38 in the top cover member 18.

By virtue of the construction of the top cover assembly 16 in relation to the upper member or tray 26, a slot 34 is provided into which a fiche can be inserted for cleaning between the ledges 32 and 36. The latter have retaining elements or shoulders 40 and 42 for retaining cleaning elements 44 which may be mounted thereon. In the normal use of these cleaning elements, the fiche is inserted between the cleaning elements 44 when the ledges 32 and 36 are in their positions shown in FIG 2, and then by depressing the push button 24, additional pressure will be exerted on the fiche by the cleaning elements 44. Then, while maintaining such pressure, the fiche can be withdrawn from between the cleaning elements 44, thereby wiping them free of any soil that may appear on either the upper or lower surfaces thereof.

Each cleaning element 44 is preferably formed by extruding a base member or extrudate 46 from a suitable organic plastic material such as a high impact styrene so that the extrudate has a cross section of a relatively flat C-shape with inwardly facing shoulders 48 at the opening of the C for cooperating with the shoulders 40 or 42 in retaining the cleaning elements on the ends of the ledges 32 and 36. As can be readily understood, the cleaning elements can be snapped over the shoulders 40 or 42, and they can be removed from the ledges merely by sliding them endwise off the ends of the ledges. For the purpose of cleaning the fiche, which normally are transparencies, microfilm, and the like, a suitable cleaning cloth 50 covers the outer surface of the extrudate, as is shown best in FIG. 4. One such suitable cloth which may be used for this purpose can be selected from the cloths sold by FilMagic/Distributors Group, Inc., l-l4th Street, N. W., Atlanta, Georgia 30318, under the trademark FilMagic Cloths, which are silicone treated cloths.

The column 14 of storage sections is formed from a plurality of identical trays 52, and attention is directed primarily to FIGs. 2, 6 and 7 for a description of these members. Each tray 52 comprises a square frame 54 which has a first pair of opposite sides 56 and a second pair of opposite sides 58. The upper surface of the sides 56 are recessed as at 60, and a ledge 62 projects outwardly from each recessed portion with its upper surface in the plane of the associated recessed portion 60. In a similar manner, supporting surfaces 64 for fiche project inwardly from the recessed portions 60 so that the upper surfaces are in the same plane as the upper surfaces of the ledges 62 and the recesses portions 60. Abutments 66 project upwardly from the plane of the supporting surfaces 64 to define the inward limits of the storage space that is provided for a fiche on the supporting surfaces on the upper side of each tray 52. Thus, two storage spaces on the same level are provided on each tray.

The undersurface of each tray 52, when turned at a 90 angle to an alternate position such as shown in FIG. 7 with respect to FIG. 6 provides complementary portions projecting therefrom for cooperation with corresponding parts of the upper surface of the next adjacent tray to define the storage spaces between such adjacent trays. Thus, the other pair of sides 58 of the frame 54 have on their bottom surfaces a downwardly projecting portion 68 which is shaped to fit into the recessed portion 60 of the next succeeding tray in a column to define therewith the horizontal slot 70 through which a fiche may be inserted for storage purposes. The other side of the tray also has complementary projecting portions or rails 72 which cooperate with the supporting surfaces 64 to retain the fiche in a flat position between the adjacent trays. Also forming an integral part of the frame 54 and projecting downwardly therefrom in alignment with the rails 72 and projecting downwardly beyond the lower surfaces of the rails 72 when in an unstressed position are the spring elements 74 which serve to retain the fiche in their stored positions.

The upper and lower surfaces of the tray 52 also have complementary portions for fitting one tray onto the next adjacent tray when assembling them in the alternately stacked positions at right angles to one another. These complementary portions include a male element 76 provided to fit into the female socket 78, and similarly the male element 80 is provided to fit into the corresponding female socket 82 in the upper surface of the next adjacent tray 52.

Thus, it can be seen that a plurality of fiche storage sections 84, such as are shown in FIGS. 8 and 9 can readily be provided for adding to the column of sections which form the initial installation. For the purpose of making such addition, the cover assembly 16 can be removed from the upper tray 26 and the additional storage sections can then be mounted on the upper member 26, after which the cover assembly 16 can again be positioned on the upper tray 52 forming the additional fichestorage section 83.

The turntable base 12 comprises two plates 84 which are of identical construction, one being inverted and overlying the other. Each plate 84 has an annular race 86 in which are positioned a plurality of balls 88. The latter are spaced apart by means of the ball spacer element 90. A pin or screw 92 connects the plates 94 at their common axis so as to permit relative turning of one plate with respect to the other. Each plate 84 has its corners notched as at 92 for receiving the male element 76 projecting from the undersurface of the lowermost tray of the column 14.

Essentially all of the component parts of the fiche storage unit 10 are formed from suitable organic plastic material by an injection molding process. Four different parts are required, these being the plate 84, the tray 52, the push plate 20, and the top cover member 18. A suitable plastic material for this purpose can be a medium impact styrene.

When the main components of the fiche storage unit are formed of plastic materials, they can be joined together by any suitable means. Preferably, the various trays forming the column and the other plastic members secured thereto can be joined by conventional solvent welding techniques well known in the art. When it is desired to separate two components for the purpose of adding to the capacity of the fiche storage unit, mechanical elements such as snap buttons may be used, or it is also found very suitable to solvent weld the parts together at the male elements 76, 80 and female sockets 78, 82 and then merely to insert a tool, such as a screwdriver, into the slots between two adjacent parts to break the solvent weld connection by twisting the screwdriver. Thereafter, the added sections can be introduced and the parts can be solvent welded together again.

From the foregoing disclosure it will be apparent that the fiche storage unit 10 can provide individual storage space for a relatively large number of fiche. Such fiche will be retained in a flatstate in a clean environment, and if the fiche become soiled in use, cleaning apparatus is readilyavailable for cleaning the soiled fiche.

The storage unit can readily be expended in capacity if 5 expansion becomes necessary. Also, fast identification and retrieval are assured. The fiche will have identifying'indicia on an exposed edge which will be located over the ledge 62 associated with each storage space permitting the user to select the desired fiche expeditiously. The ease of identification is further assured by the turntable base arrangement. The limited number of different parts also permits the unit to be fabricated initially and expended later at a relatively low cost.
