' SHEET 1 BF 3 INVENTOR. c/mL h. L 7'TL E ATTORNEYS CARD TRAY CONSTRUCTION AND METHOD OF FORMING SAME SUMMARY OF THE INVENTION The present invention relates to card tray or drawer constructions and particularly the type used to removably store library catalog cards.
The present tray construction includes a molded plastic tray body section; a two part molded plastic tray front section, which may be suitably affixed to a front wall of the body section by means of screw fasteners; a card holder rod removably insertable through the front section and into the body section for the purpose of stringing cards to be retained in the tray section; and a latching device for removably retaining the holder rod in inserted position. A particular feature of the present invention is that the latching device is in the form of a prefabricated unit, which is insertable through an opening into a cavity formed by the front section and thereafter automatically retained within the cavity for operation through the opening upon assembly of the front and body sections.
DRAWINGS The nature and mode of the present invention will now be more fully described in the following detailed description taken with the accompanying drawings wherein:
FIG. 1 is a perspective view of the library card file tray of the present invention;
FIG. 2 is an exploded perspective view of the card holding rod and the latching device therefor;
FIG. 3 is a fragmentary elevational view of the front section with its front half removed;
FIG. 4 is a sectional view taken generally along line 4--4 of FIG. 3;
FIG. 5 is an enlarged view of the area designated as FIG. 5 in FIG. 4;
FIG. 6 is a fragmentary bottom plan view of the front tray construction shown in FIG. 1; and
FIG. 7 is a sectional view taken generally along line 77 in FIG. 3.
DETAILED DESCRIPTION Referring more particularly to FIG. 1, l designates a library card tray or the like, which generally comprises a tray body section 2 dimensioned to receive a stack of library catalog cards, not shown; a tray front section 3; a catalog card holder rod 4 extending rearwardly through an opening 5 provided in front 3 and into tray body 2 for the purpose of stringing the library cards thereon; and a holder rod latching device 6 mounted within front 3.
Tray body 2 is best shown in FIGS. 1, 4, 6 and 7 as being of integrally formed, molded plastic construction having front, rear, side and bottom walls 10-13, respectively. As best shown in FIGS. 4, 5 and 7, front wall 10 is apertured at 14 to freely receive holder rod 4 and at 16 to freely receive front mounting screw fastener devices 17. Front wall 10 is provided with an appropriate number of forwardly projecting front positioning studs 19, which are preferably arranged concentrically of apertures 16. As will be apparent from viewing FIG. 7 front wall 10 is downwardly and rearwardly inclined, such as to permit bottom wall 13 to project forwardly of the base thereof and define a shelf or ledge 20, whose function will be hereinafter described in detail.
Holder rod 4 is shown in FIG. 2 as including an end mounted, enlarged pull knob portion 22 having a forward portion 23 of generally rectangular configuration and a rearward portion 24 of cylindrical conically shaped configuration. Oppositely facing surfaces of forward portion 23 are provided with a pair of grooves 26a and 2617, which are arranged within a common plane extending substantially perpendicular to the axis of holder rod 4. It will be understood that from section opening 5 is preferably formed with a configuration complementary to that of forward portion 23, thereby requiring the rod when inserted therethrough to present one or the other of grooves 264 and 26b in operative association with latching device 6, as shown in FIG. 5. Also, it will be understood that in the preferred embodiment illustrated in the drawings, forward portion 23 is dimensioned such that its forwardly facing surface 28 is arranged flush with the front surface of front section 3 when the holder rod is in properly inserted position and a coil spring 29 provided to move the holder rod from its inserted position when released by latching device 6. When coil spring 29 is employed, rearward portion 24 is dimensioned such that the spring is freely received therearound for abutting engagement with a rear edge surface of forward portion 23.
Referring to FIGS. 4, 5 and 7, it will be seen that front section 3 is of essentially hollow, rectangular construction and generally includes molded plastic front and rear halves 30 and 32, and a pair of generally L- shaped metal reinforcing plate inserts 34, which together with latching device 6, are adapted to be positioned within a cavity 36 defined by halves 30 and 32 in the manner to be described.
When halves 30 and 32 are joined, openings 39 and 52 are arranged in axial alignment; drawer pull 56 freely projects forwardly of front panel 38 through opening 40; required numbers of rear panel ribs 62 are arranged in supporting engagement with the rear surface of front panel 38 in order to prevent collapse of the front section and plate insert tabs 72 are arranged in engagement with or in close proximity to the rear surface of front panel 38 in order to retain the plate inserts in position on studs 64 and to assist in preventing collapse of the front section. Also, when the front section is assembled, front panel rib 47 and required numbers of rear panel ribs 62, such as those designed as primed in FIG. 3 and the inner or forwardly facing surface of rear panel 50 cooperate to define guide or front, top, opposite sides and rear positioning surfaces, which positionally orient latching device 6 within cavity 36 when such device is inserted through opening 49, as best shown in FIGS. 3, 4, and 7. Further, as will be apparent from viewing FIG. 7, rear panel ribs 58 and 58a are arranged for cooperation with the rearwardly facing surface of front panel 38 and top flange 42, respectively, to define an elongated cavity 80 for receiving contents identifying card 59, which may be removably inserted through side flange opening 48 for viewing through front panel opening 41.
Latching member 92, which is pivotally supported by pin shaft 94 intermediate its ends, includes an operation end portion 106 having a forwardly projecting operating tab 108 and a forwardly offset latching blade end portion 110 having a beveled edge 1 12 arranged to extend substantially vertically within cavity 36 when latching member 92 is in its latching position.
Drawer 1 is assembled from its component parts by slideably inserting latching device 6 through opening 49 into cavity 36 to position top, front, opposite sides and rear surface portions of mounting member in engagement with the above mentioned cavity positioning surfaces; positioning coil spring 27 within opening 52.; and then fixing front section 3 to tray body section 2 by means of devices 17, the latter extending through tray front wall openings 16 forwardly into plate insert threaded openings 76. As will be apparent from viewing FIG. 7, when sections 2 and 3 are thus joined, the enlarged rear end of coil spring 29 is automatically locked or retained between tray front wall 10 and projection 66, and ledge 20 is arranged in abutting engagement with the rear surface of rear panel 50 and in underlying engagement with mounting member tab 100. Ledge 20 and tab thereafter define cooperating abutments, which serve to prevent removal of mounting member 90 of the latching device from engagement with the cavity positioning surfaces outwardly through opening 49. Also, when the drawer is assembled in the manner described, plate inserts 34 function both to clarnpingly secure the front and tray body section together and to transmit loads applied to drawer pull 56 directly to tray front wall 10.
Holder rod 4 may then be inserted through front section opening 5 and tray front wall opening 14 for the purpose of removably retaining appropriate library cards within the tray. Towards the end of inserting movement, cylindrical-conical portion 24 engages beveled blade edge 112 to thereby effect pivotal movement of the latching member in a clockwise direction, as viewed in FIG. 3 away from its latching position; forward portion 23 thereafter engaging the forward end of coil spring 29 to initiate compression thereof. At the completion of holder rod inserting movement, whereat the forward face 28 of knob 22 is preferably flush with the front surface of front panel 38, spring 29 is fully compressed and one or the other of grooves 26a, 26b is arranged in transverse alignment with beveled blade edge 112, thereby permitting the latter to be seated within such groove and be subsequently maintained in latching position under the resilient bias of spring 96. When it is desired to remove holder rod 4 for the purpose of adding or removing cards therefrom, it is merely necessary for the user to rub his thumb or finger along bottom flange 43 in a direction from right to left, as viewed in FIGS. 1 and 3, such as to engage tab 108 and thereby pivot member 92 in a clockwise direction, also as viewed in FIG. 3, in order to remove blade edge 112 from groove 26b against the bias of spring 96. Upon removal of blade edge 1 12 from groove 26b, coil spring 29 is operative to move the pull knob 22 from its normally seated position within the front section in order to permit the former to be grasped and manipulated by the user as necessary. Of course, spring 29 is preferably relatively weak, since it would be undesirable to propel the holder rod at a speed or through a distance which might cause injury to the user.
If flush mounting of holder rod 4 is not required, and the rod is permitted to project forwardly of the front section .when fully inserted, ejector spring 29 may of course be eliminated.
