ApplicatiomMay, 13, 1947; Selitl'-'1 I0.--747L652 2Claims; 1.. invention. relates to hinges. and" more particularly to a. sliding hinge;

It is an object ofthisinvention. to provide-an. improved hi'ngeof the kind. tobe moreparticua larl'y described hereinafter for mounting. radios. or other. such devices. in. a closedcompartment' inzsuch amanner that-thefzrameof theradio is hingedly connected. tothe cabinet-101'. compartment. w'herebythe. frame orbasemay be inverted=aboutthe hinge -forworkingon. the wiringof the radiousually; locatedon. the under side. ofthe frame or base. The hinge is so located that it\ will be: concealed withinv the. cabinet or compartment in. the closed position .of theradio and. may slide-outwardly to permit rockingthe frame. to the invertedpositionin the open position oi the radiowhere:- work may; be performed. on. the radio without removingit entirely fromthe cab.-- inetor. compartment" This-type of'hingeiszparticularly adaptable to a radio as. installed. in. automobiles, as. police scout cars and others where the radios mustrbe maintained in. perfect condition;

Another. object.of thisinventionlis to provide a hinge of. this kind whereby a-irameor baselmay. beslidably and rockably. mounted as in a cabinet. and. so constructed and arranged that the base may be bodily removedfrom. attachment. to the. cabinet by merely raising the base from. the hinge.

Still another object-ofthis invention is toprovide a-hingeof this kind/for mounting aradio base. orthe-like. in a-containerwhereby the radio. may bereadily removed for working onv the underneath wiring A similar hinge or. book may be mounted on a. bench ina shopso theradio when removed from the cabinet may be sup-- portedona similar hingein the-shop by merely engaging the lugs or: pintle. in. thehooks; where it-may be worked on freely.

A further object of thiss invention is to provide a hinge of this kind for-'removably' supporting a'radio base in a cabinet or compartment in such a manner that the base maybe slidably and rockably mounted ion thevcabinet in such a manner.- that.it.is lfirmly supported in its. open position and held from dropping off the hinge and.

2.v tion and details ofconstruction disclosed in-the drawings andspecification; and then more-particularly pointed: out in the appended claims In the drawings;

Referring. to the drawings, the numeral l0? designates gener'allyth'e'cabinet for a radio or the like, as more particularly-designed for sup porting'azradio in: an automobile: The cabinet l0. isprovide'dfwithz a. hinged front wall H" for removin'gi'th'e chassis: or base: of therra'didwheri' it'EiSI-IIE'OESSZI Y to perform-work on' thewiring' or other'maintenan'ce:

While thetfront wa'll? H is'hingedly connected to l the cabinet" I0; hinged? orr'ro'c'king' movement of -the frontwall is usually insuflioient to* rock the ra'diobase or chas'sis tb aTposition-suitable for working on: the-wiring which is disposed on the lower side ofthe bas'ez For-working on'this wiring it is" usually most convenient" t'o dispose the radio in as near: to an inverted position aspos sible. By using a hinge of the'kind? to be more specifically described liereinafter, the front wall H and radio chassis l2 may be rocked from the:

cabinet I'll to an inverted position: slightly for"-' will permit the free access to the wiring below beremovedfor" removing the chassis from the cabinet. 7'

The" supporting means I 6 by which the front wall ll andradiochassis IZ 'are mounted in the cabinet I tl' inclu'des an" elongated-plate I I which.

. is 'adapted to' b'e' fixed totheiinsideiof the opposite sidewalls Ofltlifiiifbififii loby bolts IBso'r other: suitabieifasteningr devices: The plate I! is dis-"- posed'ir'earwardlyrrof therfront edge of. the cabinet I'D-3 and: fronti wall: Ha Thezlate I1 is formed: with;a;longitudinallwextending: groove. IS on one:

3 side thereof to provide a guide or channel between the plate I! and the wall of the cabinet. The groove |9 extends throughout the length of the plate I? opening at each end.v The plate I! is further formed with an elongated slot 20 near the rear end thereof, the slot 20 opening through the plate to communicate with the groove l9. As shown in Figure 4, the slot 20 opens rearwardly of the plate together with;

An elongated supporting bar or being disposed between the plate H and the wall of the cabinet in the groove l9.

For limiting the sliding movement of the arm 2| a stop pin 22 is fixed on the arm near the rear end thereof. An upwardly directed bill 24 is fixed to or formed on the forward end of the arm 2|. The bill 24 is formed with a downwardly extending arm or shank Z and a forwardly and upwardly extending hook forming arm 26. The bill 24 is bent inwardly along the length of the shank 25 as at 21, to provide clearancefor the attaching bolt 28 which engages in the hook'26. A pin or pivot 28 is fixed to the base or chassis I2 of the radio at a point rearwardly of the front wall l I a distance substantially equal to the width of shank 25 and spaced abovethe bottom extremity of the chassis a' distance substantially equal to the length of said shank 25. The pivot pin 28 is formed with a threaded shank 30, engaging through the base |2, with which a nut as 3| is'engaged for fixing the pin 28 thereto. The pin 28 is further formed with an enlarged annu lar head 29 spaced outwardly from the wall of the base I2. As the pin 28 is engaged in the hook 26, the hook is disposed between the head 29 and the base |2 to hold the base against lateral movement in the hinges.

' In the use and operation of this hinge l6 when the radio is completely assembled and installed the pin 28 is engaged in the bill'24 and the arm 2| is retracted into the plate IT, as shown in Figures 2 and 4. For rocking the chassis of the radio to an inverted position, the front wall H is pulled forwardly so the arm 2| slides forwardly in the plate until the pin 22 engages'the'extreme forward end of the slot 20. The base or chassis |2 may then be pivoted about the pin 28 in the bill 24 to an inverted position as shown in dotted lines in Figure 2, whereupon the rear surface of the front plate I will engage the vertical back edge of the elongated shank 25 and the under edge of arm 2|. The spacing of each pin 28 relative to wall II is arranged to allow for rotation of the chassis substantially 180 degrees about the axis of said pins so as to provide for inverted positioning of the chassis with the under side faced upwardly in full view of a repairman and ready of access thereto. Certain types of wiring of radios of this kind connect the radio to the speaker and sources of power through slide plugs not shown in the drawings. The plugs will be disconnected upon sliding movement of the chassis forward from the cabinet l0.

r At certain times it may be desirable to remove the entire radio chassis from the cabinet I!) and hinges 6. This may be readily accomplished by rocking the front wall I and chassis l2 partly about the pin 28 and lifting the entire assembly from the hooks. For supporting the radio thus removed on a bench in a shop similar hinges may be fixed on a suitable base so that the pins 28 may be engaged in hooks similar to the hooks so that no other attaching means need be provided. When the radio is completely put back in condition it may be re-installed by merely engaging thepins 28 in the hooks, rocking the chassis |2 to the horizontal position and sliding the arms 2| back in the plate I do not mean to confine myself to the exact details of construction herein disclosed, but claim all variations falling within the purview of the appended claims.

What I claim is:

1. In a cabinet having an open front, of a pair of oppositely disposed longitudinally grooved guide members fixed on inner side walls of the cabinet, each of ,said guides being formed, with a longitudinally extending slot communicating with the groove formed therein and having a closed end disposed from the open front, an elongated arm slidably carried by the groove of each guide member, a pin carried by each arm engaging in said slot of said guide, said arms having dependent ends formed at right angles and extendable relative to said guides, said dependent ends having forwardly extending and upwardly opening hooks, a base member slidable within the cabinet, said base member being formed with a vertical front wall extendinglaterally beyond the dependent ends, transverse pivot members carried by said base and engageable in said hooks, said vertical front being engageable with the rear edges of said right angled ends of the arms after withdrawal of said base from the cabinet and pivotal movement of 180 degrees for securedly suspending said base cabinet, an elongated arm slidably carried by the groove of each guide member, said arms having dependent ends formed at right angles and extendable relative to said guides, said dependent ends having forwardly extending and upwardly V opening hooks, a base member slidable within the cabinet, said base member being formed with a vertical front wall disposed forwardly of said dependent ends, oppositely disposed transverse pivot members carried by said base and engageable in said hooks, said transverse pivot members being disposed rearwardly of said front wall and upwardly from the bottom of said base member, said vertical front being engageable with the rear edges of said right angled ends of the arms after withdrawal of said base from the cabinet and pivotal movement of degrees for suspendingly securing said base in an inverted position from said hooks.
