REFRIGERATOR DOORS AND DOOR SHELVES 2 Sheets-Sheet 2 INVENToRs rca/wl.

BY 'Mamas r i United States Patent v.O

The present invention lrelates to refrigerator doors and door shelves, and is particularly concerned lwith an 1mproved construction of refrigerator doors and door shelves. S

Oner of the objects oft the inventionis the provision of an improved refrigerator door and door shelf construction, in which the 'door shelvesl are wholly detachable without the use of any,toolsso that considerable labor is saved in the construction and assembly of the door with the shelves and so `that the shelves may be removed by the housewife for, washing yand cleaning of the shelves; and washing the inner door panel without encountering Athe door shelves as' obstructions.

Another object of the invention `is .the provision of I an improved door and shelf assembly in which the shelves serve the additional purpose of bracing and increasing the rigidity ofthe rinner panel of the door. l

Anotherobject of the., invention is the provision of an improved doorshelf lconstruction and mode 4of attachment which allows for ventilation'by passage of ,air between the shelf and theinner door panel, and through the bottom of the vshelves,themselves to promote a circulation of air about the commodities carriedby the n n outer shell are,secured together by meanstofgheaded shelves. i .y

Another object of the invention is the provisionk of an improved Ishelf which may be provided with a suitable wire bail for extending upwardly above the door shelf land preventing bottles orother long articlesfrom tippingolfthe shelf. .y l.

Another objectof the invention is the provision of an improved door shelf construction and form of attachment to the door panel, whichy is engaged-: more tightly with the door panel by theweight of the articles acting on the shelf when it isv loaded.

Another object of the invention is the provisionjof .ani

improved door shelf adapted to servey as egg trays, being provided with apertures within which eggs may be seated to prevent them from rolling around the shelf.

Other objects andadvantages of the invention will be apparent from the following description and the accompanying drawings, in which similar characters of reference indicate' views. f Y f Referring to the -two sheets of drawings accompanying this specification, g

Fig. l is a side elevational view of an insulated refrig'erator door embodying the invention;

Fig. 2 is an'outside elevational view of the door;

Fig. 3 i-s a top plan viewof the door;

Fig. 4 is atop plankview ofone of the door shelves shown in connection with fragments of the inner panel;

Fig. 5 isa front elevational view of one of the door shelf units; y

Fig. 6 is afragmentary lsectional View takenv on the plane of the line 6 6 of Fig; 5;

Fig. 7 is a fragmentary sectional view taken on thesimilar" parts throughout -the several" -2 planeof the line 7-7 of Fig. 5, looking in the vdirection of the arrows; and i .Y

Fig. 8 is a Vfragmentary .top plan View` of the door showing the vmodeof assembly of the inner `antlouter doorpanels anddoor seal. n 'j Re'ferringto, Figs. 1 to 3, the insulated refrigerator door {is indicated in its entirety by thev numeral 10,7and it preferablylincludes an. outer metal shell 11, anV inner insulated panel 12, having anv intermediate llingof suitable yfibrousginsulation. Y

The outer'shell 11 may comprise a :stampedqsheet metal member provided with avfront wall 13 and with arearwardly extending top Wall 14, abottom WallV 15 and .two side walls 16 and 17. v

.Thewalls 14-1?, r,which surround the face panel 13, are provided with an inwardly' extending flange 18 on the back side ,ofthe outer shell to be .usedin attaching the outer shell to the inner panel 12. *Y

y The outer shell 11 .is preferably madeV of steel. and has roundedicorners 19, 20 at the top, and relatively square corners 21, 22 which are slightly rounded at the bottom.

l The yinner panel 12y of the door is provided with a bordergil'ange 23a1l around its edge, which `serves as an attachrrrent,flange4 and. is located in the same' plane so that it may be attached to the inwardly extending. attaching angelS onthe outer shell. g 5

The attaching flange 23 of the inner panel terminates short .ofy the outer edgeof the door so that. it maybe mounted ina door seal 24, which comprises a resilient rubber memberhaving a rubber attachingflange 25, spacedffrom its main body 26 by a groove .27 whichl receives thev edges of theinner panel. a

The main bodyof the door seal 24 is hollow/and ovalf in shapey so that ,its curved face 28 lmay engagea flat4 face ange fon thevrefrigerator cabinet to effect an` air tight seal betweenvthe Vdoor and the cabinet. Y. v

The doorseal24, inner panel 12 and flange ltljofy the threaded members 29, which engage resilient nutsi30- on, the inside ofthe shell flange 18. n ,z Thus theheads ofthe threaded members 29 are llocated beneath thedoor seal body 26 and the shell is` attached;

to the inne r,. .panel at regularly spaced points alliaround the exterior of theinner panel, forming a closed container forthei-nsulatiomVVA Y .t r v Y The inner panel- `12 is preferably molded out of a paper,

, base fiber which =is .laminated` andimpregnated with a phenolic condensation compound and coated on lthe inlcenter 33 of the door.This gives the inner panel van. l

inward curvature which tends to stiften it .and surround; the inward curvature with an outwardly bulging rectangular frame near the attaching flange. y 3,.

The inner panel 12 may be made all of o-ne piece orv it may be made of two separate sections, tongue and grooved together midway ybetween the top and bottom of the door. Y n Y The door seal 24A mayA be made of a single molded resilient rubber member/,or it may be' made up of oneor more lengths of the door seal material'mitered at thea corners and` suitably joined together by means of rubber..

cement. Y f f.

kThe-door is preferably provided at the top of its innerV panel with' a multiplicity of air ventilation openings34` .'.L f. f ,J ,Y .f .l si and with a similar number of openings 35 at-thebottom of the door at the bottom corner.

Each shelf unit is provided lwith 39,1 which is integrally ljoined to an ornamental `front 40,"5thelatter extending upward atright'angles'.

"The bottom wall 39 may ,becurved at 41, along its rear edge to correspond to the curvatureofthe dished portion First theu top` of the shelf is tilted forward toward the v 33 lof the 4inner'` panely V12; but` the'V curved edge 41 is `spaced from the inner panel 12 by arplurality offoutwardly extending lugs' 42","43 at each end,- and 44, 45 intermediate the ends.

f Thelugs 44, 4s areca'red bythe Bottom wall Vas, and e they have'a reinforcing :connection with thebottom wall inthe form-of tapered ribs 46.` i Y. l Thus the bottom wall 39 is spaced from the inner panel, leaving a crack 47 forl passage of airandv facilitating the circulation `of air to'c'ool the productscarriedbythe shelves.:` 'Y Additional air circulation through the 'bottom wall`r39 is` permitted by a mnltiplicityof staggered ,circular apertures 48, located in the rbottom wall39, and also servin to seat eggs when a shelf-is used as yan egg rack.

- The inner panel `12 is :provided with a pair of rectangular apertures-.49, Fig. ,7, for passing a downwardly hooked extension 50, which is carried by each lug 44 anl`45f.V Each lug 44,"45 has a` downward extension 51 belowfthe` hooked extension 50 for engaging behind the'inner panel12.

The length of the aperture above 'the hooked extension 50 is sufcientsto pass the entire hook'edfexrtension 50 when'the bottomwall 39 is tlexedor bentjupward;` and this makes thelbottom wall "quickly detachable by bending its'hooks upward; i

The front wall 40 of each :shelf unit maybe straight andjritis `provided with a pair of-"inward' bevels 52,' 53, joined at a'center line 54 forornamental purposes. At Aeach end the front wall Ml'curves/'inward toward the inner door panel 12,-andY has a roundedcomer at 55' and 56, and a thickened end wall 57 and 58;` This thiclr-v enedend `wall may actually'be hollowand is formed with" two? thin walls 59 and 60, the edges 61 ofwhich are curved to lit against the outward bulge 32 of the inner panel 12.` i

The inner panel 12 is provided with apair of `'r'.:ctangular apertures 62,l located tofreceive outwardly" extending lugs V63, carried by each end wall 58.

wardly extending hook 65. 'Theapertures 62, Fig. 6, are

long enough in; a verticalldirectionlto'pass the entire lugA when the entire shelf unitV 63, with its upward hook 65 is moved downward.

i y. Thus` each end ofthe shelf unit` is provided near upper` edge with lugsvr63 `for engagement with the inner To take a shelf unit' off thebottom'39 is bent upward near its middle portion, thusimoving both hooks 50 up ward until the hook 51 clears the aperture 49 in each case.

Then the bottom of the shelf is pivoted away from the door panel, moving the lower hooks 50 out of the apertures 49. r

When this has been accomplished the bottom of the shelf is free and the entire shelf may be moved downward, the lugs 63 at eachfend moving downward until the panel edge at the.holes62 moves out ofthe groove 66.

Then the lugs 63 lmay bewithdrawn from the apertures 62, thus freeingl the shelf unit at each end and at the top. y

It is a great advantage `to be able to removethe shelf unit because then the inner door panel maybe wiped clean of its entire area without leaving a streak ofdirt where the shelf bottom is and where the'shelf is attached.

The shelf also maybe cleaned separately with soap and water and replaced as follows:

Hooked `extensions 50 will not pass into lapertures, 49 until"`the Abottom 39 is actually bent "After the hookedextensions 50 have entered the apertures .49 `the bottom 39' is'permitted to bend downward again' intola straight,cndition, causingthe depending hooksf51 toiengagetheinside of the inner panel 12.

Thusv each shelf unit isquickly attachable and quickly detachable, saving the"expense of threaded bolts and other fasteners, and saving the labor of securing these parts together withthreaded members.

Y

It will'thus be'observed that we havev invented an improved ,door construction whichmay bemanufactured very low in cost and A`wliichrequiresa minimum amount of labor in its assembly and hasa minimum number of parts. A C

`The present shelves may be removed at `will by the user, thus 'facilitating thecleaning of the shelves and inner panel; and they maybe replaced with a minimum amount of labor. Y y v, Y

"f While we -have illustrated a preferred embodiment of our invention, many modifications may be made without departingfrom the spirit of the invention, and we do not wish to be limited tothe precise details of construction set forth, but `desire to avail ourselves of all changes within the scope of the 4appended claim.

Having thus described our invention, what we claim las new and desire' to secure `by Letters Patent of the United States, is: i

i A refrigerator cabinetVdoor-panel which is outwardly .bowed fromfthe` cabinetV and' inwardly recessed for shelves, and which comprises an integral insulating panel of sheet material adapted toV cover the inside of a refrigerator door, said panel removably supporting a plurality of shelf units extending into the recess of said panel and projecting oppositely toward the cabinet, each shelf .unit having an aperturedbottom wall, a side wall and two end walls, the bottom wall and end walls` conforming to the curvatureof the. panel, said shelf `units carrying a plurality of rigid supporting lugs having bodies projecting through lug apertures inthe panel while the unit engages the front of the panel, each lug having av hook-shaped end engaging the back of Vthe panel adjap cent each lug aperture, thev lug Lapertures being of suchv length and clearance vertically that the hook-,shaped ends may pass through' the lug apertures; there 'being a pair of lugs, one at each end wall of the shelf near the top thereof, with an upwardly extending hook, and there being another pair of lugs carried by the bottom wall of the shelf intermediate the shelf ends, each having a downwardly extending hook, the said lug apertures being located in alignment with the bodies of said lugs with the vertical clearance of each lug aperture extending oppositely to the hook end of its lug, the said shelf unit being resilient and bendable centrally to permit one pair of lugs to be inserted and hooked in their apertures upwardly, and thereafter bending the shelf until the other pair of lugs have their hooks passed through their apertures, the latter lugs springing down with the straightening of the shelf, until the two pairs of hooks are oppositely secured in the panel.
