Tillot'son, Allison Pai-k, Pa., assigner to .Blaw-Knox Company," Pittsburgh, Pa., a corporation of New J ersey Application January s, 1946, serial Nq. c3a's54 l This invention relates to a tilting-lift door and, in particular, to a dooradapted for buildings Where a very Wide, unobstructed opening de@- sired. a
Doors of great width are necessary in certain types of industrial buildings, 'for example, airplane hangars, in which it is necessary to pro`v vide a wide span free from obstructions to permit the entry and exit of aircraft having 'a long Wing spread. Many lof these doors are of the tilting-lift type, i. e., they are supported adjacent their upper corners by trolleys secured near the upper edge and travel-ing on' substantially horizontal tracks. Additional' trolleys pi'vted to the sides of the door on a horizontal axis parallel to the bottom edge of the door and spaced theres above, travel on tracks curving upwardly and.
ection when disposed in a vertical plane and. supported at their ends, by reason of their cone siderable height. When tilted'to' open position, however, objectionable deection may occur un= less special precautions are taken in the design. Usually these result in a heavy massive con.; struction. While additional supporting rollers traveling on horizontal tracks .between the side edges of the door may be provided.. forA supporte' ing the upper edge, the lower. edge of the .door
is without support between the upwardly and in= wardly curving guide tracks `at the extreme sides of the opening in the building wall.
I have invented a novel .form of .tilting-liftk door provided with auxiliary Ysuspension meme.
bers for supporting the door paneliat points ine termediate the side edges thereof, wherebyex cessive deflection is avoided without `requiring the construction to be such as to increase. thev weight of the door as -a whole. Invarpreferre'd embodiment, I provide suspension members see cured at their ends to the door panel adjacent the upper and lower edges thereof, and traveling,
on fixed rollers. The portions of the 4suspension members intermediate their ends are spaced from the door panel on the external side thereof.v The suspension members may be in the form effarigid curved track or a flexible cable and, in either case, serve to support the door panel 'in'- tei-mediate its side -edges and yavc'nid v excessive deflection'thereof. i
'.5 claims.. (o1. L20-.19)
2 A. complete understanding 'of the inventi may be obtained from the following detailed .dee scription which refers to vthe accompanying' drawings illustrating a preferred embodiment and a modication. In the drawings,
Figure 1 is a diagrammatic. elevation of a building having a door embodying. the invention, the,
door being shown in partlyopen position;
:Figure 2` is a partial section taken .along the plane of line AII--fII of Figure 1; .Y
. Figure-3 is asimilar sectiontaken along theplane of yline III-#II'I-.jof Figure 1, parts beyond the plane'of section being omitted;
lFigure 4 is a section similar to Figure 3 shows ing parts beyond the vplane of section, the door being in closed position; Figure 5 va vview similar .to Figure .4 showing the door in open position;
Figure .6 isa .diagrammatic perspective view showing a modied construction with the door closed; and v Figure 7 is a similar View showing the door Open;
Referring now in detail to the drawingsv and, for the present to Figures 1 through 5', a building I0, for example, an .airplane hangar, `comprises structural columns' Ill, lintelbeam's I2 carried thereby and roof trusses .I3 .extending between the beams. A :roof covering I4 is carried .by purlins I5 extending across the trusses ..I3. The
ends I6 andone sidev I'I .of the building .may 'be' closed by any desired construction. The .other side of the building -is .open between corner columns I I. A tilting-lift door panel I8 is adaptaV ed to close the open side of the building.
The panel I8 Vhas trolleys vI.9`secured thereto adjacent `the` upper" corners. The trolleys :Il
travel on tracks 20 extending inwardly from `.the
My improvement in the meansforisupporting the panel I8 `czornprises one .orlmore suspension means 24, preferably vspaced inwardly freni-tile side edges ofthe panel. ln the form of .the in` vention illustrated in llguresI l through 5;;.each suspensionmeans comprises .a curved track 25' secured to the panel adjacent the upper and lower edges thereof but spaced from the panel at points between said edges. Specifically, the tracks 25 are curved beams bowed outwardly from the door panel on the external side thereof. The tracks 25 ride on xed trolleys 26 carried by the building frame. The curvature of the tracks 25 is such that the rollers 25 will carry a lportion of the weight of the panel at all points in its upward tilting movement to open position. That is to say, the curvature of the beams is dened by the locus of the axis of rollers 26, if the ldoor were held stationary and the building revolved relative thereto.
n.It will be appreciated that the rollers 26 support a portionof the weight of the panel I8, thus reducing the span between points of support from the distance between the tracks 20 to the distance between them and the suspension means or beams 24. This materiallyreduces the deflection of the. panel between supports and permits a much lighter construction to be employed than would otherwise be necessaryto keep the deflection below the permissible maximum. As the panel I8 approaches the fully open position of Figure .5, the support afforded by the rollers 26 is applied adjacent the lower edge of the panel. The trolleys like those shown at I9 cooperating with the intermediate horizontal tracks 2| will support the upper edge of the panel in open position. Instead of relying on tracks 2 l the winches 28 may be disposed as shown in the drawings so thatwhen the door is open, the vcables 21 exert asubstantial vertical component. of force on the suspension means or beams 25, thus making it unnecessary to provide `the tracks 2l and trolleys cooperating therewith. A
VWhen it is desired .to close the door, operation of the Winches 28 to pay out the cables 21 permitsthe panel to travel downwardly in the tracks 23vr and tilt back to vertical position as it descends. The beams 24 continue to support the panel intermediate the tracks 23 particularly in that portion of the travel of the panel before it reachesv substantially vertical position. It will be evident that the beams 24 may be provided with lattice members to constitute a truss, instead of using the simple bow-shaped beams illustrated in the y drawings.
Y Figures 6 and '1 show a modified construction of. the door panel 30 adapted to close the open side of a building 3|.A The panel has cables 32 secured adjacent the lower edge thereof at points spaced across its width.- The cables are trained around sheaves 33 journaled inside the building adjacent openings 34 through which the cables extend. The other ends of the cables are secured to the upper edge of the panel as at 35. Rollers 31 at the upper corners of the panel travel in horizontal tracks 38.
It will be apparent that when the upper edge of the door panel is drawn inwardly as by the cable and winch arrangement referred to above, the cables 32 will support the panel at the extreme side edges thereof and also at the intermediate positions occupied by the cables and sheaves. In other words, the construction of Figures 6 and '1 dispenses with the necessity for the trolleys 22 and the guide tracks 23 of the construction first described, yet supports the panel at intermediate points as well as the side edges thereby `materially reducing the span between points of support and likewise reducing the maximum deflection of the panel between supports.
It will be apparent from the foregoing that the invention is characterized by important advantages over tilting-lift doors as previously constructed, particularly in the case of doors having va large span, such as those required for airplane hangars. By means of the construction de- .,scribed, such doors are supported at points between the side edges thereof. The intermediate supports are effective at the upper edge of the door in the beginning of f the tilting movement of thefpanel but remain xed as the panel continues to move and approach the lower edge as the panel moves into substantially horizontal position in which the deflection thereof between supports under its own weight is a maximum. The invention is simple and inexpensive, the acl,- ditional parts and structural members required being simply the suspending beams or cables with their supporting rollers or sheaves. By virtue of these intermediate supports the door may be made lighter and less rigid than heretofore since the possible deflection of the panel when in horizontal position is greatly reduced by the intermediate suspension means.
Although I have illustrated and described but a preferred embodiment of the invention and a modification, it will be recognized that changes in the arrangement of the parts or details of construction may be made without departing from the spirit of the invention or the scope of the appended claims.
