Coulee, Ripon, Wis., assigner to McGraw- Edison Company, a corporation of Delaware Application November 15, 1956, Serial No. 622,484 7 Claims. (Cl. 16-140) The invention relates to hinges for use with the swinging lids or doors of cabinets and the like, and it is more particularly concerned with hinges for lids or doors designed to swing about a horizontal axis. The present application is a continuation-in-part of my copending application, Serial No. 562,419, led January 3l, 1956, now abandoned.

One object of the invention is to provide a cabinet door hinge of the above general character which permits the door to swing freely through a major portion of its range of travel and which automatically exerts a restraining action at each end of the swing to prevent the door from slamming against the cabinet in either fully open or closed positions.

Another object is to provide a hinge operative to apply a frictional snubbing or braking force to the door as it swings in either direction beyond predetermined limit positions while leaving the door toswing freely between such limit positions.

Still another object is to provide a hinge in which the snubbing or braking force can be adjusted.

A further object is to provide a simple sturdy hinge -for cabinet doors which effectively prevents the door from slamming as it is opened or closed.

Other objects of the invention will become apparent from the following detailed description of the preferred embodiment illustrated in the accompanying drawings, in which:

Figure l is a perspective view of a washing machine cabinet equipped with a lid or door mounted by a hinge embodying the features of the invention.

Fig. 1A is an exploded perspective view of a preferred form of the hinge.

Fig. 2 is a fragmentary sectional view through the top of the cabinet taken in a vertical plane substantially on the line 2 2 of Fig. l.

Fig. 3 is a perspective view of another form of the hinge.

Fig. 4 is -a sectional viewA taken in a plane substantially on the line 4-4 of Fig. 3.

Fig. 5 is a transverse sectional view of a modiiied form of the hinge.

Fig. 6 is a fragmentary perspective view of still another modied form of the hinge.

Fig. 7 is a fragmentary sectional view of the cabinet taken in the same plane as Fig. 2 but on a somewhat larger scale and showing the limit positions between which the cabinet door swings freely.

While a preferred embodiment of the invention and certain modications thereof have been shown in the drawings and will be described herein in detail, it is not intended to limit the invention to the specific forms disclosed. On the contrary, the intention is to cover all moditcations and adaptations falling within the spirit and scope of the invention as expressed inthe appended claims.

By way of illustration, the invention has been shown as installed in a sheet metal cabinet 10 which, in this in" strip with the sockets 21 suitably spaced apart. In this I stance, serves as the casing of a washing machine. The cabinet 10 is generally rectangular and has a flat top panel 11 formed with a raised ledge 12 along its'rear edge for convenience in mounting certain control elements. An opening 13 (Fig. 2) in the top panel 11 affording access to the interior of the cabinet is titted with a closure in the form ofa lid or door 14 pivoted to swing about an axis adjacent Iand parallel to the rear edge of the door. The full range of movement of the door is preferably between the closed position shown in full lines in Fig. 2 and the fully open position shown in broken lines in the same figure. The particular door shown is generally rectangular and comprises a sheet metal panel formed with a depending flange 15 around its marginal edge.

To provide for its pivoting or swinging between the closed and open positions, the door 14 is mounted on the cabinet by means of a hinge 16. This hinge comprises two members 17 and 18 adapted to be attached respectively to the cabinet and to the door and connected to each other for relative pivoting movement by a hinge pin or pintle 19 extending through axially alined sockets 21 and 22 provided on the members. In the particular embodiments illustrated, the member 17 is attached to the cover 14 as by bolts 23 while the member 18 is attached to the cabinet top panel 11 by bolts 24.

In accordance with the invention the parts constituting the improved hinge are constructed and arranged in a novel manner to permit the members 17 and 18 to swing freely between predetermined limit positions and to exert a restraining force on movement of the members beyond either limit position. Such limit positions, of course, are determined in accordance with the particular range of movement required ofthe lid or door with which the hinge is to be used and the limits are set so that the free'swinging range is somewhat less than the full range of movement between fully open and closed positions.

In carrying out the invention, the hinge pin socket or sockets of oneof the members is dimensioned for a relatively loose iit with the pintle so that that member may swing freely thereon. Through the medium of spaced abutments and a cooperating stop provided on those relative swinging parts, such free swinging is restricted within thep redetermined limits. Movement beyond either limit position results in the pintle being carried along with the hinge member in a rotating movement.

The pintle socket of the other member is constructed and arranged to apply a frictional resistance to such rotation of the pintle and thus restrict free movement of the hinge member and the door to which it is attached as the door approaches either end of its range of movement. Preferably the arrangement is such that the resistance opposed to rotation of the pintle is sufficient to prevent the door or lid from falling freely of its own weight, yet permitting it to be pushed into open or closed position with relatively little effort.

The hinge members 17 and 18 may be made of any suitable material as, for example, steel or brass, and may be made in various shapes or styles. In the preferred form shown in Fig. 1A of the drawings, the member 17 is made in two parts, each shaped to provide a single socket 21 adapted to be positioned at opposite ends of a socket 22 provided on the member 18. It will be understood that the number and arrangement of the pintle sockets may vary in accordance with the particular use for which the hinge is intended.

Referring in more detail to the hinge construction shown, each part of the member 17 comprises a flat metal plate 23 with one edge portion 24 curled into cylindrical configuration to define the socket 21. It will be understood that the hinge member 17 may be made, if desired, with the two plates 23 constituting a single elongated rattache tendedweb of the angle member'may be centrally "slotted to'form a second strap 26 spaced from the strap'ZS 'and similarly curled over to define afsocket '22 as shown'f in Fig. 3.

For cooperation with that form of hinge-inember 18, the member 17 is formed with a single socket V2d dirnensioned to iitr between the spacedsockets 22.

The cooperating stops and abutments which deiine the vfree swinging limits of the two hinge membersmay take Avarious forms and may be variously placed for the performanceo'f their limiting functions. Thus, in the' hinge form shown in Fig.` 1A, the curled ledgefportion of 'one part of themernber 17 is notched todene opposed yabutments 27 vand 2Sl spaced apartcircumferentially of vvvthe socket 21 formed .by the curledportion 24 of the inem ber. In this case a radially projecting stop 29 is provided on the pintle 19 ,and located so that it extends into they notch between the abutments when the hinge elements are assembled. As shown, the stop comprises a lug formed integrally with the head of the pintle.

Other arrangements of the stop and abutments are shown in the modiiied hinge forms illustrated in Figs. -3-7 ofthe drawings. ln the hinge form shown in Figs. 3 and '4, for example, the curled edge portion 24 of the hinge member 17 is formed with a generally centrally located Vslot Si) delining abutments 31 and -32 spaced apart circumferentially of the socket 21 formed by the curl 24. s top providedon the pintle 19 and locatedso .that it projectsinto o r through ytlieslot 3@ for cooperation Vwith the.abutmentstalternately as the Arneiribers L17-.and 18` pivot .relative to A` each other about 'the pintle. 'The stop shown comprises a lug of rectangular cross-section welded `or othe'iv/ ise rigidly secured to the 4pintle andprojecfingradially therefrom. It will be appreciated that a sir'nple pin 33h such as that shown in `Fig. 6 may be employed as a stop if desired.

When the Yabutments 2 7-28 or 31-32 are provided on the hinge member 17, the socket or sockets 21 for that member are dimensioned to receive the pintle 19 with a relatively loose fit so that the member v17 can swing freely on the pintle until the stop 29 or 33 engages one or the other of the abutments. Further movement of thehinge member 17 carries the pintle along With'it, rotating the pintle about its axis in the sockets 22 of the companion hinge member.

ln the manufacture of the hinge, the lstrap 2S for-ming the socket 22 is bent over far enough to dimension the socket for receivingthe pintle 19 with a relatively tight it. Where a second socket is provided, as in the hinge shown in Fig. 2, the strap 26 is bent over similarly to the strap 25. Preferably the end of the strap or sti-'aps are extended along the body of the member andf generally vparallel thereto. The end of the strap may be left free, as shown in Fig. 3, and the stiftness of the metal relied on to establish and maintainthe. desired frictional. engagement. Preferably, however, means is provided for adjusting the frictional grip of the socket on the pintle to simplify. initial assembly ofthe hinge and. provide for compensa tingV for wear id use. While they grip or fric` tion adjusting meansmay-be of any. suitable construction, aV simple and satisfactoryadjnsting-.meansfor that purr' pose. comprises a screw-y 37 I inserted j throughi ai clearance hole 3 8 in the extended portiony of the vstrap 25A andi threadedinto a tapped hole 391 thefbody oranglei web: of the member 18. Accordingly, the socket caoba-cons traste@ to increase' the grip 0ntieepintle by simply turning .inthe screw or thegripcan be" eased' bybacking'i olthe. screw. The restrainingaction or frictiona'l drags; en thehinged lid may thusbe established quicklygand: the initial assembly o f fthe apparatus-and reads'. justment canv be 1 made with a; simple: screw driver.: necessary becauseotwear. iriuse.;

The dimensioning or adjustment of the socket forming strap or straps is such that the frictional engagement of the socket forming parts and the pintle opposes a substantial resistance to the rotation of the pintle and thus applies a snubbing or braking force to the movement o f the hinge member 17 beyond either of the limit positions delined by the two abutments. It will be appreciated, of course, that the abutments can be provided on the socket 22 if desired for cooperation with a stop suitably positioned on the pintle 19. Insuch cases, the socket or sockets 22 are designed to receive the `pintle with a loose t while the socket 21 is shaped and dimensioned toifrictionally resist rotation of Atlieepintle.

The hinge formshown inFig.. 5 diters from that above discussed in that abutments 31a and 32a are provided on the pintle 19a while a stop 33a is provided on the hinge member 17. The abutments, in this instance, are defined by the ends of a suitable-grooveS in the pintle 19a. The stop 55a may constitute a Ypin or the like driventhrough an aperture in the curl 24. Alternatively,

-a stoppin can beprovided in either or both of the straps '25,26 for cooperation with suitably located stops on the pintle. yIn either case, the hinge members 1 7 and 18 are freely swingable between predetermined limits and, when swung beyond such limits, the pintleis carried along with fthe stop-equipped hin'gemember. The socket or sockets vof ythe other member rare dimensioned to frictionally grip the pintle and oppose a substantial resistance to its rotation. Fig.-6 shows a hinge structure generally similar to that shown in Figs. 3 5; I n this instance, howeveri the stop 332 comprises' Sapin drive'nintoa 4'suitable hole drilled inthe-pintle. vb'utmnts 'S1-iv 'and 32b5'inth'is instance; arefformed by a notch 36 in one edge bf thecurl 24; yPfahl -thepreviously Adiscussed hinge forms the abttn'ents may be provided in association with the sockets 22 if desired. YIn any vcase, the socket` or sockets l'with lwhich the abutments are associated are diinensioned fr a loose it with the pintle while the other socket or sockets are diinensioned for frictionally gripping the pintle t resist its rotation. It will be apparent from the foregoing that a hinge constructed in accordance with the invention in any of the forms above described effectively prevents the lid or door with which it is associated from slamming when either `opened or closed. The door is left free to swing freely through Ythe major portion of 'its range` of travel and at .both ends of that range it his 'snubbd orbrakecl to prevent the door from falling of its own weight, yet permitting it to be pushed easily into fully open or closed positions. In the case of cabinets of the type shown where the' full range of movement of the door is in the neighborhood of 150, the stops 27-28 or 3 1-32 are' preferably spaced apart to allow a' free swing of approximately Accordingly, the door 14 can be swung freely from the fully open position in which it is resting on the ledging 12 to the partially closed position shown in full lines in Fig. 7. Even though released at that position the door will not fall and slam against the Ycab'ii'iet due to the resistance opposed to' the rotation of Vthe hinge pintle. However, light push easily swings the door the rreist"ofthev vy to closed position; V

Compensation for wear is made in the same way when necessary after a long period of use.

It will be evident from the foregoing that the invention provides a hinge of novel and advantageous construction particularly suitable for doors or lids closing openings in the tops of cabinets. The novel hinge effectively prevents the door from slamming when it is opened and closed and yet offers a minimum of interference to the manual opening and closing of the door. The hinge is simple in construction and thus inexpensive to manufacture. It is rugged and durable and capable of giving troublefree service over long periods of use.
