Applicationnled December 28, 1928. 'Serial No. 329,053;l
. This invention relates to the art of buildings and, more particularly, to an improved door construction.
It is an object of this invention to provide a'new and improved door construction.
It is another object of this invention to provid-e a door composed of a plurality of similar hinged sections'which are independf` ently supported at theirupper ends.
It is a further object-of this invention to provide a light Weight inexpensive door .which can' be easily opened or closed by sliding it around the corner. l
It is a still vfurther object ofthis invention ,to provide a door composed of a plurality", of sections which are movable with respect to one another and which are lapped to form tight joints between the individual sections.
It is also an object of this invention to profdr overcoming wind resistance'. to opening.
It is still another objectQofthis invention to provide dow sash.
Vith the above and other objects'in view,
.which will be apparent as the description proceeds, I have set forth my invention in thel following specification and'have illustrated it in the accompanying drawings, in which:` Fig. 1 is a fragmentary plan view, with the roof removed, of a portion of an air-plane la'ngar provided with my new and improved oor;
Fig. 2 is an inside elevation corresponding toFig.1;"f v Fig.l 3 is a rear elevation, on a slightly smaller scale, of two adjacent sections' embodying my invention; V Fig. 4 is a horizontal section on an enlarged sc-ale, ont-he line 4 4 of Fig.' 3', showing the interior construction ofthe individual secl tions, the lapbetween sections,thehinge construction, and the window construction;
Fig, 5 is a verticaltransverse section, .on the linei'- jof Fig. 3, showing the overhead suspension, the means for closing the tops of the sections, the .means for adjusting the height of the individual sections, and the wind thrust roller;
vide a doorI constructiona'vhich has means.
doorsections equipped with win- Fig. 6 is a vertical vlongitudinal section on the hne.6-6 of Fig. 5; Fig. 7 is a' vertical transverse section, on"- the l1ne 7 7 of Fig. 3, showing the 'meansl for closingthebottoins of the sections, the bottom guide c onstructiomand the shield therefor; 'i Y F' is an inside elevation corresponding to Fig. 7 and also showingthe hinge construction; .x f
Fig. 9 is a plan view of thcur'ved track for guiding my door around tlie corner;
Fig. 10 1s a verticalftransvers'e section, on the line 10 10 of Fig. 9, showin the .interior construction of the curved trac and one of the meansfor guiding the cable around. the
corner; and-Fig.`11 isa vhorizontal section on the line 11-11 of Fig; 3, showing the details of applicants channels. i In the accompanyiri drawings, and refer-70 ring particularly to Flgs. 1 and y2, 10 desi natesahangar provided with a stationary si e Wall 11 and amovable door 12 which, either separately or in 4conjunction with a second door, forms a closure' for one side of the hangar 10. The walls which are not shown may be stationary or movable, `and the sta-.
tionary walls may be of any suitable type as they form no part of the presentl invention.
The door 12 comprises a pluralit of sub- 80 stantially similar sections 13, whic are secured to one another by hinges 14 and are supported y overhead rollers 15 that enga e a track 16 carried by any suitable framewori,
such as the I-beams 17 and truss members 18. 85
, Referring particularl to Figs. 3-8, it will be seen that the indivi ual sections 13 each consist of a pair of similar reversely-ar- 'ranged U-sha ed channels 21 and 22 Which terminate n1n a-terally-extending flanges V23' 90 and 24', preferably' of u ne ual width. To assemble the sections one c annel 421is reversed with respect to a correspondin channel 22 so as to5bring into engagement t e corresponding anges 23 and- 24' of adjacent ,95 channels, whereupon .these are securely fastened to ther, as by spot welding. A top closure p ate 25 is secured in place a short distance below the upper ends of the channels 21 and l22', Iand a corresponding bottom clo- '100 .-therethrough.
a 'lock nut 49. The bolt 39 is preferably atf tached to the center of the plate 25 'so that the weight ofthe door section tends ,to hold itin a verticalposition. As a result of this mounting it Will be 4obvious that each section 13 may be raised or lowered with respect to f i .the position ofthe rollers 15 by loosening the lock 'nut 49, and turning the bolt .39 in the requireddirectiom)that is, clockwise to raise the section. and counter-clockwise to lower the section; after which the`lock nut 49,'is
` turned upto's'ecure the section in the adjusted position. The cutv away .portion 29 in each section 22 permits the insertion of a p wrench to effect this adjustment. y
The track 16 is preferably closed on its top 41 and'sides -42 but its bottom 43 is provided Witha central slot 44, and for this purpose the bottom is slit longitudinally and the adj acentI portions are turned inwardly to form guides 45 for the yoke 36 of the IJroller turned portion 45 andthe corresponding side `wall 42 forms a guideway 46 for the corresponding roller 15. f
One of the obstacles. which normally renders large exterior doors difficult to slide is the Wind resistance, and I have devised a simple means of overcoming this, which consists in the provision of a wind thrust roller mechanism. rlhe space between 'each in-V -47 for each of the supporting yokes 36.
While this roller mayftake various forms, v.I prefer to use a sleeve' 47 which is telescoped overthe yoke 36 prior to mounting the yokes 35 thereon. The roller 47 is retained in the propei` position on yoke 36 in any desired manner, as by a sh'ulder`48 formed integrally with the yoke, or a collar mounted thereon. f
The bottom of theldoor is preferably guided in itsopening and closingmovements by a' curved T-shape'djguide track 54, which is secured to the foundation or fioor\ 55 of the hangar in any convenient manner, and the bottom of each door 'section 13 is preferably provided withpa pair ofantifriction rollers 56 which dependl from a supporting plate 57 secured tothe bottom `closure plate 26 in any convenient manner, as by a bolt 58.'l
As shown in Figs. 7 and `8,'the bottom of each door section 13 is preferably provided with a iap 6Q, whichmay be of an suitable material, such las canvas or rubher, to protect the bottonn guide construction from Luthe elements and to make a tighter fit for the bottom of the door. The lap'60 maybe at.
l tached to the door'sections in any convenient manner, as by the bolts 61', and is preferably al continuous member.
means for opening and closing the door I prefer to attachcables 62 and 63' to the extreme door sections, and this is preferably done by. connecting the cables'to the studs 34 the center door section, in the case of 'a double door, runs through thetrack 16, to a pulley mechanism 64,,locatediK-the centerrof the For the kpurpose of provlding a. convenient i izo i `door opening, where it i's-rversed, passes to the cornerof the"building outside of the.
Y track, and is there turned substantially par-v `-'allelA to the lside wall 11 of the building by.
one o r more' pulleys 65, carried by the track or track support)v This end of the cable'62 then goes to an operating mechanism 66,
which maybe of "any desired type and either p hand driven', asshown, or provided rwith .a suitable electric drive (not shown) vif desired.
The other cable 63 is attached tothe extreme door section and, passing through the. track 16, is attached to the. operatingfmechanism 66. For a building provided y'with only one door` in a side the mounting 'ofthe cable mechanism -differs from that just described merely by arranging the pulley mechanism 64 at the opposite side of the building instead -'of in the center of the door opening.'
-slideagainst the rollers 67 and'binding is avoided.
As'bestshown in Figs. 3, 4, and 5, any of the sections 13 may, if desired, be provlded with window sash 70. These may be. of any desired type but asuitable type is one pro-` vided with a metal framework 71 or 72 that has openings to receive panes of glass 73,
which are secured thereto by retaining strips 74 bolted tothe framework. The sash 7() may be secured. to the door sections 13'in any desired way, as by spot welding. Likewise, the sash may be provided with double panes of glass, as in framework 71, or with single' vas panes as in framework 72. I prefer to make the sash framework out of angle iron having a central body portion 7-5, which forms the l "window casing, and flanges 7 Gand 77 turned Vat right angles to the body portion'and in opposite directions therefrom, as the flanges 76 `form effective retaining means to hold the framework in position in the section 13 and the fianges 77 for'mDa convenient supportE for the Aglass pane 7 3. The framework may be fornied from similar angle iron portions,
as in framework .71, or from angle irons whose body'portions 75 are of unequal length, as in framework 7 2. In practicev the parts of the framework are. insertedl from opposite sides of the section 13 and spot welded, after which the .glassis inserted. y
In caseswhere it is not'desired to have the door openaround the corner" the hingesr14` may .belreplaced by spot-welds (not shown),
14, 16,18, or 20V gauge.
thus forming a rigiddoor construction.
While my door may be made of any desired p material, I have found a copper bearing steel well adapted for the urpose. The channels 21 and 22 may be malde of any desired width or length, and'of any desired gauge, such as It will be apparent that I have devised a doorvco'listruction which maybe made inany desired size and which is `simple in construction, of light weight, is easily assembled, and will form a strong, tightinsulated door that can easily lbe opened' or closed by moving the cables in theidesired direction. It will also be apparent that my new andimproved door construction is independent of the 4regularity of the foundation, and that settling of the latter or excessive wind resistance will not affect its` easy and rapid operation.`
As many .apparently widely different embodin'ients of'this invention maybe made without departing fromthe spirit and scope thereof, it is to'be understood `that I do 4not limit myself to the specific lembodiments thereof except as defined in rthe appended patent claims.4 y
