United States Patent() HINGE lJohn Sunko,Elgn,-lll., assignorto'MotorolmInci, Chicago,`l1l., a corporation of Illinois Application September 21, y195B, SerialrNo.:3,81;I72 2 claims. (c1. 22o-31) hinged at one edge and are usuallyheld Ltogether by a suitable clasp at an opposite edge. y:It is most desirable to provide such a receptacle for a radio receiveror the like that lends itself readily to a molded construction-and in which the two sections may be hinged together yquickly -and conveniently.
Itis, accordingly, an object of the presentinvention Vto provide an improved hinged structure comprising Ia pair of casing sections hinged Itogether in an improved andl sirnpliiied manner.
Another object'of the invention'is togprovide-suehfan improved hinged structure that-may be manufactured simply and expeditiously and without the need -for heat fusing or other relatively difficult and time-consuming operations.
Another object oftheinventionisztoprovide such an improved hinged structure that lends .itself readilyito a molded construction.
A feature-of the present invention is-,the provision of a hinged structure that comprises afpair of casing sections having v.slots formed in theiradjacenttedges and which are hinged together by a simple hinge-pin that may be readily inserted in the slots and which has a bent-over end portion which engages a notch in one of the casing sections and holds the pin against longitudinal movement.
Another feature of the invention is the provision of such a hinged structure in which the casing sections have slots with open sides molded in their adjacent edges, and in which the sections are hinged together by a simple hinge pin retained in the slots by means of a pair of washers which also function as bearings for the sections.
The above and other features of the invention which are believed to be new are set forth with particularity in the appended claims. The invention itself, however, together with further obje-cts and advantages thereof, may best be understood by reference to the following description when taken in conjunction with the accompanying drawing in which:
Figure l is a perspective View of the hinged structure of the invention;
Figure 2 is an exploded view of a portion of the structure; and
Figure 3 is another view partly in section of la portion of the structure.
The invention provides a hinged structure which comprises a first section having an edge with a pair of aligned slots formed therein and spaced along the edge. The rst section has an opening therein adjacent the edge and adjacent one of the pair of slots at the end thereof remote from the other of the pair of slots. The structure also includes a second section having an edge with a slot in fhinged relation 'portion extending beyond vthe one of vthe pair of `'slots "herein and extending along the'edge'.
Yhas alpair'dfzfmolded integral bent-overprotuberances f 2,765,901 ce Patented Oct. 16, 1956 Yformed therein and alignedV with the pair of slots menv#tioned above.
A hinge .pin is providedwhich extends through the'pair of slots in thefrs't section and through -the-slotin thesecondsection for maintaining the sections The hinge pin has Ia bent-over end adjacent the opening Vreferred to above, the end rportion being disposed in the opening to prevent longitudinal movement of the pin.
fflWith referenee'now to the drawing, -the hinged struc- :ture `illustratedltherein includes Ya first-casing section 10 vand a Asecond casing `section, Y11. VVThe .casing 4sections preferably are of moldedzconstruction and eachihas a "top 12 fwithfour integral .sides 513 extendingrperpendicu- 'larly therefrom.
One'of-the sides 13 of the casing-'section 11-termi `nates @in van -edge having Yan elongated notch vv14 vformed 'This v`edge l'also and I6 disposed at the end of notch v14 `and defining Vva-paipo'ffaligned slots 17 and 18 extending parallel to vftheedge. "Slots '17 and'flS are each-open'alongvone side :tofac'ilitate the moldingrprocess, and at least slot l'17 -is yopen-affits outer-end for reasons tobe described. The
:edge referred vto 4'above has V-a further notch 219 formed I disposed in theelongatedmotch 11:4 -in section 111. 'The protrudingportion 20l defines V'a slotextending parallel to and aligned with slots 17 and 18.
'A hinge'pin' V21 =,Xten`ds-through slots V17 and' 13 .in lsec- #tion f11 and=throughthe-aligned slots Vforrne'd by portion T20, thereby maintaining -thesectionsin'hinged relation. =A pair of washersZZ and "23 is' mounted'on the/hinge pin --anddisposed adjacent vthe inner ends o`f slots 17 and 18. These washers functionas bearings for the structure land also :.serve Vto -retain pintZl within vthe=slots A-17 Land y18 -by engaging the -rear of notch 14.
Hinge pin 21'has `a bent-over Vend yportion 2A-which A-exten'dsbeyond the outer=end of LVAslot 17fand=whichfis turned into notch v19 -to prevent longitudinal movement of the pin and to retain the pin in thel-slot.
The hinged structure may be assembled simply and conveniently in the following manner. As previously mentioned, casing sections 10 `and 11, together with the protruding portions 15, 16 and 20, may be formed by usual molding techniques. The casing sections are laid open at approximately with the hinge receptacle slots aligned to receive the hinge pin. Washers 22 and 23 are then dropped into position between the respective inner ends of portions 15 and 16 and the ends of portion 20. Hinge pin 21 is then inserted through slot 17, washer 23, the slot in portion 2G, and through washer 22 into slot 15. The end portion 24 of the hinge pin is then turned into notch 19 to prevent longitudinal movement of the pin. In this manner, the washers retain the hinge pin against lateral movement within slots 17 and 18 and the end portion 24 in notch 19 retains the hinge pin against longitudinal motion. As shown in Figure 1, it is preferable to provide two hinge assemblies in the hinged structure, one Vat each end.
The invention provides, therefore, an improved hinged structure in which a pair of casing sections are held in hinged relation by a simple pin rather than a more complicated form of hinge and which does not require heat sealing or other complicated expedients for retaining the hinge in the sections. The hinge retaining slots in the casing sections of the present invention are shaped to facilitate molding of the sections. In each instance, the
v hingedrrelationV between the sections isv establishedrby means of afsimple metal rod or pin which is bent over at one end and retained :in the manner taught herein to Vprevent longitudinal motion, and a pair of washers is disposed on Vthe pin which functions as bearings and lretainers for the assembly.
While a particular embodiment of the invention has been shown and described, modifications ymay be made and it is intended in the appended claims to cover all such modifications as fall within the true spirit and scope of the invention; Y
