CABINET STRUCTURE Filed Feb. 24. 1966 United States Patent 3,352,613 CABINET STRUCTURE William J. Morris, Woodbury, and Robert C. Simmons,

Merchantville, N.J., assignors to Philco Ford Corporation, a corporation of Delaware Filed Feb. 24, 1966, Ser. No. 529,772 8 Claims. (Cl. 312-8) ABSTRACT OF THE DISCLOSURE A unitary, molded plastic hinging and latching device provides for pivotal operation, as well as assembly and disassembly of a phonograph changer pan with respect to its cabinet. The hinging device includes a slot for engaging a pivot pin extending laterally from the changer pan. A catch also molded into the bracket resiliently engages another laterally presented pin on the changer pan to hold it in a stored vertical position.

This invention has to do with cabinet structure, and especially to cabinet structure for housing photographs or the like.

Portable phonographs of one Well-known type comprise a record player and changer-pan or shelf assembly arranged to be stored in a vertical position Within an upright cabinet. When the phonograph is in use, the changerpan assembly is folded or tilted outwardly of the cabinet and downwardly into a horizontal, record-playing position.

It is a general objective of the present invention to provide improved hardware for mounting player and changerpan assemblies of the aforementioned type. It is a more specific objective to provide inexpensive, unitary, preferably molded plastic, hinging devices that facilitate pivotal operation, as well as assembly and disassembly, of the changer-pan with respect to the cabinet.

Summary of the invention Cabinet structure embodying the invention comprises phonograph apparatus featured by the provision, in one molded device, of the following: means aifording changer- =pan pivotation, with means to retain the changer-pan pivot pin; a catch to hold the changer-pan in its stored vertical position; a hinged, two-position stop adapted in a raised position to facilitate installation and removal of the changer-pan during assembly and disassembly, respectively, and in its normal lowered position, to stop the changer-pan in a horizontal recordplaying position; a first latch molded into the device to hold the stop in its recited raised position; and a second latch molded into the device to hold the stop in its normal lowered position. The device also includes means molded therein for storing a record adapter spindle.

The manner in which the foregoing as well as other objectives and advantages of the invention may best be achieved will be more fully understood from a consideration of the following description, taken in light of the accompanying drawing in which:

FIGURE 1 is a perspective showing of portable phono graph apparatus embodying the invention;

FIGURE 2 is a view, partly in section and with parts removed, looking generally in the direction of arrows 22 applied to FIGURE 1, 'and illustrating several of the operational features of the invention;

FIGURE 3 is a view similar to FIGURE 2 and illustrating an operational feature, and

FIGURE 4 is a somewhat enlarged perspective showing, with parts removed, of apparatus illustrated in FIG- URES l, 2, and 3.

3,352,613 Patented Nov. 14, 1967 With more particular reference to the drawing, and first to FIGURE 1, a portable phonograph cabinet 10 includes an upwardly extending, main box-shaped portion 11 provided with loudspeakers 12 at each side. In accordance with conventional practice, and by Way of example alone, loudspeakers 12 are hinged along vertical corners, as at 13, so that they are pivotable between their stored, folded, positions (not shown) and their illustrated in-use positions. It will of course be understood that the loudspeaker construction is a matter of choice, and need not be further described for an appreciation of the invention to be disclosed in what follows.

A record changer 14 is hingedly mounted for pivotal movement about a horizontal axis, from a vertical position (broken lines, FIGURE 3) Within the main cabinet portion 11, to a horizontal record-playing position (FIG- URES 1 and 3), in which position it extends partially to the outside and partially to the inside of the mentioned main cabinet portion.

In particular accordance with the invention, and as best seen in FIGURES 2 and 3, hinged movements of changer pan 14 advantageously are provided by a pair of individual hinging devices comprising hinge brackets 15, in cooperation With horizontally extending hinge pins 16 carried by the changer pan. It is a feature of the invention that each bracket may, if desired, comprise an integral member molded of plastic material. Left-hand and righthand brackets 15 are provided, and it will be appreciated that each bracket is a mirror image of the other. In view of this similarity, illustration of only the right-hand bracket 15 is undertaken for purposes of disclosing the invention. The brackets 15 each are disposed intermediate opposite confronting sides of main cabinet portion 11 and changer pan 14, and are conveniently held in place by screws of the type seen at 18. Each bracket 15 includes a lower open-ended slot 17 (see particularly FIGURES 3 and 4) and an upper, open-ended slot 21.

As further seen in FIGURE 3, a pair of hinge pins 16 on the opposite sides of changer pan 14 are disposed for pivotal movements in lower slots 17. Another pair of pins on changer pan 14, one of which is illustrated at 22, are receivable in the upper slots 21, when the pan is pivoted to a vertical position for storage. The slots 21 and pins 22 cooperate to lock the changer-pan in its stored position (broken lines, FIGURE 3). When the pan is moved to its horizontal position (full lines, FIGURE 3), pins 22 disengage slots 21 and the rear, upper portion of pan 14 is translated into abutting engagement with ledge portion 29 of a detent means 23. The pan is held in this horizontal, record-playing position by engagement of means 23 with an upper surface portion of the pan until such time as it is again stored.

In especial accordance with the invention, each detent means 23 is hinged about a pintle 24, and the means 23 and pintle 24 are molded in the body of material comprising bracket 15. Pintle 24 preferably comprises a reduced, highly flexible section of the molded bracket that connects means 23 to the main body of the bracket. A synthetic organic thermo-plastic material, such for example as polypropylene, has from which bracket 15 may be molded. The invention is not limited to use of this specific material, although it i especially adapted to fabrication by molding from flexible plastic materials characterized by relatively high resistance to fatigue failure under repeated flexing.

With reference to FIGURES 2, 3, and 4, detent means 23 is pivotable between a lower locked retracted position (FIGURES 3 and 4) in which it is effective to hold ohanger-pan 14 in its horizontal, record playing positron, and an upper locked extended position (FIGURE 2) permitting removal and installation of the changerpan.

been found suitable as a material- Detent means 23 includes a pair of molded

latch elements

25 and 26 cooperable, respectively, with molded

latch surfaces

27 and 28 on bracket 15. Element 25 and surface 27 interlock by virtue of the inherent resilience of the material from which the device is molded, to hold detent means 23 in the upper position, as will be understood from FIGURES 2 and 4. Element 26 and surface 28 interlock to hold detent means in the down position illustrated in FIGURES l and 4. Detent means 23 includes a pan-holding surface or ledge 29 On a portion thereof adjacent latch element 26. In the lower latched position of detent means 23, ledge 29 is so positioned as to provide a stop engageable with the upper horizontal surface of the changer-pan to hold the pan in its horizontal position.

As illustrated in FIGURE 2, detent means 23 in its upper latched position, is so spaced from lower slot 17 as to permit the pan to be manipulated in order that hinge pin 16 may be inserted in or removed from lower slot 17. Hinge pin 16 is held in place by a resilient molded loop 30 that projects into slot 16. In order to install or to remove pan 14, detent means 23 is latched in its upper position, and pan 14 is then manipulated through positions as shown. In one of these positions pin 16 is caused to deflect molded loop 30 (FIGURE 2) to permit movement of the pin to or from slot 17.

As illustrated in broken lines in FIGURE 3 pin 22 is held in place by a flexible lip portion 31 of upper slot 21 to provide for storage of the pan in its vertical position.

In further accordance with the invention, at least the right-hand bracket 15 illustrated, has molded integrally therewith a clip 32 for storing a record spindle adapter 34, such for example as a 45 r.p.m. record adapter of the flat type. Clip 32 comprises an L-shaped shelf and vertical side Wall member 33 in combination with a vertically extending, resilient wall 35 curved to accommodate lateral insertion and retention of the spindle in the clip, the .shelf member having the detent 27 molded integrally therewith.

7 'From the foregoing it will be appreciated that the invention affords improved hardware for mounting record player changer pans, the invention affording an inexpensive, unitary, molded plastic hinging device that facilitates pivotal operation, as well as assembly and disassembly, of the changer-pan with respect to the cabinet.
