Int. Cl. A47b 88/00 US. Cl. 312-330 2 Claims ABSTRACT OF THE DISCLOSURE A two part plastic front construction for library card drawers or the like, wherein a rear half of the front carries a tray pull or handle for projection forwardly through an opening in a forward half of the front. The front is mounted on and force applied to the tray pull transferred to the card tray body by metal reinforcing brackets positioned between the halves prior to assembly thereof. The halves are provided with aligned openings to receive a card follower or holding rod mounting latch device retained therein by a guide-retainer formed int'egrally with and projecting rearwardly from the rear half.
This is a division of application Ser. No. 89,312, filed Nov. 13, 1970.
BACKGROUND OF THE INVENTION Library card trays are conventionally formed by mounting a solid wood front on a tray body formed of wood, metal or plastic. While attempts have been made to replace wooden fronts with ones formed of plastic, such constructions have not met with acceptance in the trade for various reasons, including their inability to withstand the rigors of use in a library.
SUMMARY OF THE INVENTION The present invention is directed towards a plastic front construction particularly adapted for use on library card trays, which is designed to Withstand the rigors of use in a library.
The plastic front of the present invention is formed with rear and forward halves, which are bonded together about their marginal edges to form an essentially hollow, rectangular front construction. The halves cooperate to define a drawer contents identifying card holder, and are provided with aligned openings to receive a card follower or holding rod mounting latch device, which is retained therein by a guide-retainer fixed to the rearwardly facing surface of the rear half.
A particular feature of the present front construction is that of permitting the tray pull or handle, which is carried by the rear half to freely project forwardly through the forward half, and providing a pair of metal brackets, which are pre-positioned within the front during assembly, and serve both to mount the assembled front on and to transfer forces applied to the tray pull directly to the card tray body. This construction greatly reduces the loadings which would otherwise be imposed on the front, thereby permitting the front and particularly the forward half to be of thin sectioned, lightweight design.

DETAILED DESCRIPTION Referring more particularly to the drawings, 1 designates a library card drawer or the like, which generally comprises a tray body 2 dimensioned to receive a stack of library catalog cards, not shown; a tray front 3; and an assembly including a catalog card holder rod 4 extending rearwardly through front 3 into tray body 2, and a follower rod latch device 5 mounted Within front 3.
Holder rod 4 and latch device 5 are of a construction similar to that described in US. Pat. 3,260,263. More specifically, it will be seen by referring to FIG. 5, that latch device 5 includes a tubular metal holder 6, which is formed to define an upstanding annular end rim or flange 7 and an inwardly deformed locking lip 8; and a spring metal finger 9, which is suitably fixed inwardly of holder 6 in axially spaced relationship to lip 8. Also, by reference to FIG. 5, it will be seen that follower rod 4 includes an end mounted knob portion 4a and a conically shaped operator portion 4b spaced axially therefrom. As is conventional, rod 4 may be locked within holder 6 by engagement of locking lip 8 with the forwardly facing or radially extending surface of portion 4b. Portion 4b may be subsequently released from locking engagement with locking lip 8 by moving knob portion 4a, so as to depress spring finger 9. The arrangement for mounting latch device 6 within front 3 will be hereinafter described in detail.
Tray body 2 is best shown in FIGS. 1, 2, 4 and 5 as being of integrally formed, molded plastic construction having front, rear, side and bottom walls 10-13. As best shown in FIGS. 2, 4 and 5, front wall 10 is apertured at 15 to freely receive follower rod 4 and at 16 to receive front mounting screw fasteners 1'7, and is provided with an appropriate number of forwardly projecting front positioning studs 18 preferably arranged concentrically of apertures 16.
Again referring to FIGS. 1, 2, 4 and 5, it will be seen that front 3 of the present invention is of essentially hollow, rectangular construction and generally includes molded plastic front and rear halves 20 and 22; and a pair of generally L-shaped metal reinforcing plate inserts 24, which are to be positioned within a cavity defined by halves 20, 22 in the manner to be described.
Front half 20 includes a front panel 26, which is provided with circular opening 28 for receiving tubular holder 6 and rectangular openings 30, 32; and rearwardly extending top, bottom and side marginal flanges 34, 36 and 38, which define a continuous recess 36a. The side flange 38 viewed in FIGS. 1 and 2 is additionally provided with a rectangular opening 40, which is vertically aligned with front panel opening 32.
Rear half 20 includes a rear panel '42, which is provided with a circular opening 44 for receiving tubular holder 6; circular openings 46 for receiving positioning studs 18; and circular openings 48 for receiving screw fasteners 17. Extending forwardly from rear panel 42 is an apertured drawer pull 50; positioning and supporting ribs 52, 52; a plurality of spacer ribs 56; and a plurality of studs 58 for positioning or orientating plate inserts 24. Extending rearwardly of rear panel 42 in axial alignment with opening 44 is a tubular holder mounting extension 60 having radially through slot openings 62.
Plate inserts 24 are shown in FIGS. 2-4 as being stamped from sheet metal to form a marginal flange portion 64 and a tab portion 66, which project in opposite directions from a planar portion 68 having threaded openings 70 and smooth bore openings 72.
In assembling front 3, plate inserts 24 are first mounted on rear panel 42 by inserting studs 58 in plate bore openings 72 in order to positionally align threaded openings 70 with rear panel openings 46 and 48. When thus positioned, each of plates 24 extend into close proximity to the base of drawer pull 50, as best shown in FIG. 3. Thereafter, front halves 2t), 22 are permanently joined together by fixing the marginal edges of rear panel 42 within flange recess 36a, such as by fusion or adhesive bonding techniques.
When halves 20, 22 are thus joined, tubular holder receiving openings 28 and 44 are arranged in axial alignment; drawer pull 50 freely projects forwardly of front panel 26 through opening 30; at least spacer ribs 56 and preferably supporting rib 52a are arranged in supporting engagement with the rear surface of front panel 26 to prevent collapse of front 3; and plate tab portions 66 are arranged in engagement with or in close proximity to the rear surface of front panel 26 in order to retain plates 24 in position on studs 58. Further, as will be apparent from viewing FIGS. 3 and 4, rear panel ribs 52 and 52a are arranged for cooperation with the rearwardly facing surface of front panel 26 and top flange 34, respectively, to define an elongated cavity 74 for receiving a drawer contents identifying card 76, which may be removably inserted through side flange opening 40 for viewing through front panel opening 32.
After assembly of front 3 has been completed, latch device 5 may be mounted therein by inserting tubular holder 6 through aligned openings 28 and 44 until holder rim 7 abuts against the forwardly facing surface of front panel 26, as best shown in FIG. 5, and thereafter swedging or otherwise deforming portions, such as a pair of tabs 6a, from the rear end of holder 6, such that tabs 6a extend radially into slot openings 62 of mounting extension 60, as best shown in FIG. 6. Holder 6 is thus permanently supported within and constrained from rotation relative to front 3.
Drawer front 3 may be subsequently mounted on tray 2 by first positioning studs 18 within back panel openings 48 in order to automatically align threaded openings 70 of plates 24 with tray front wall openings 16, and thereafter threading screw fasteners 17 into openings 70 until rear panel 42 is securely clamped between tray front wall 10 and marginal flanges 64 of insert plates 24.
Follower rod 4 may then be inserted through holder 6 and tray front wall opening for the purpose of removably retaining appropriate library cards within the tray.
From the foregoing, it will be understood that a particularly important feature of the present invention is the construction wherein the drawer pull is carried by the rear half of the front and the mounting plate inserts extend laterally within the front into close proximity of the base of the drawer pull, such that drawer opening forces are transferred from the drawer pull to the plate inserts and from the plate inserts directly to the tray body via the front mounting screws. As a result, the plate inserts effectively serve to prevent bending deformation of the rear half, and thus the front half of the front, thereby permitting same to be formed of thin walled, lightweight construction,
Moreover, by forming insert plates with marginal flanges the rigidity of the plates is greatly increased and the clamping pressure exerted on rear panel is more uniformly distributed than would be the case with plates formed of planar sheet metal stock of the same thickness.
