HANGER DOOR Filed Feb. 20, 1956 Myrton MJosephson v INVENTOR. BY M f;

United States Patent O M HANGER DOOR Myrton M. Josephson, Asheville, N. C.
Application February 20, 1956, Serial No. 566,466
3 Claims. (Cl. 2016) This invention relates to a counter-balanced overhead type door and more particularly to an airplane hanger overhead door. While the door of this invention is primarily designed for use on airplane hangers, it is readily adapted to other uses such as on garages, warehouses, shipping terminals, gates, etc.
l am aware that various types of counter-balanced overhead doors have been proposed in the past. However, to my knowledge, none of these doors has heretofore been successfully used o-n an airplane hanger and, surprisingly, very few counter-balanced doors are in use on garages or other buildings requiring the use of a large door. Many airplane hangers today are equipped with sliding doors which are usually difficult to open or with an overhead roll-up type door requiring a source of power to open and close the door.
The object of this invention is to provide an easily opened, inexpensive, counter-balanced overhead type door which may, if desired, be operated manually even when the door is of relatively large size, such as on an airplane hanger. Y
It is characteristic of the present invention that the counter-balanced door pivots on a horizontal shaft extending through the door structure. The door framework is comprised of a series of spaced vertically disposed ribs on the front portion of the door and a series Of spaced vertically disposed ribs on the back portion of the door with horizontally extending members arranged between the vertical ribs on the front and the vertical ribs on the back of the door and connected to each so as to give the door a rigid, torsion-resisting Structure.
Referring now to the drawing, Figure l is a front elevation, partly broken away, of an airplane hanger equipped with a door made according to the present invention, the door being shown in closed position, and
Figure 2 is a section view taken along the line 2-2 of Figure l with the door in open position.
Figure l shows airplane hanger 10, at one end of which is provided a horizontal structural beam 11 connected to and extending from the top of vertical column 12 to the top of vertical column 13 at the opposite side of hanger 1t). Beam 11 is connected to columns 12 and 13 by any suitable means.
Beam 11 and columns 12--13 define an opening through which aircraft may be moved and which is covered by the door to be described.
A metal shaft 14 is disposed below and parallel to beam l1. Shaft 14 may be fixed to columns 12 and 13 as by means of pins (not shown) and extends completely across the end of the hanger 10. In addition to columns 12 and 13, shaft 14 is supported by three sleeves attached to the lower end of vertical rods 15, 16, 17, spaced along the length of shaft 14. Rods 15, 16, 17 are connected to beam 11 by any suitable means such as by welding.
The framework of the hanger door is comprised of four substantially identical sections connected together so as to form an integral unitary structure. The first of these sections, or the one farthest to the left `in Figure 1,
j 21,863,181 Patented Defc. 9, 1958 ICC comprises spaced vertical rib members 20, 21, 22, 23, 24, 25, on the front side of the door and corresponding rib members such as the one 26 (Figure 2) on the rear side of the door. A longitudinal Stringer 27 is disposed at the top of the do-or framework between the ribs on the front Side of the door (hereinafter called front ribs) and the ribs on the rear side of the door (rear ribS). Stringer 27 is securely connected to each of the ribs by any Suitable means. A bottom longitudinal Stringer 28 is disposed between the front ribs and the rear ribs and similarly connected to each. It will be noted that Stringer 27 is more than twice as wide as Stringer 28 with the result that the front ribs and the rear ribs are slightly bowed toward each other at the bottom of the framework. Intermediate longitudinal Stringer 29 is disposed slightly more than one-half the distance from shaft 14 and Stringer 28. Like stringers 27 and 28, Stringer 29 extends from rib 20 to rib 25 and is securely connected to each of the front ribs and each of the rear ribs.
A second intermediate longitudinal Stringer 30 is located between Stringer 29 and Shaft 14. Stringer 30 differs from stringers 27, 28, 29 in that it is rigidly connected to auxiliary stringers 31, 32, disposed normal to Stringer 3@ and extending throughout the length thereof. Members 30, 31, and 32, which in cross section define the shape of a U (as seen in Figure 2), are each securely connected to each of the front and each of the rear ribs.
Referring now particularly to Figure 2, in the upper part of the door framework, between Stringer 30 and Stringer 27, a shaft receiving member 33 occupies the space between front rib 24 and rear rib 26. Member 33, which is provided with an aperture for shaft 14, is securely attached to each of Stringer 27, Stringer 30, auxiliary stringers 31, 32 and ribs 24, 26 by any appropriate means. The aperture in member 33 .is slightly oifcenter, i. e., it is slightly nearer to the rear rib 26 than to front rib 24. A shaft receiving member similar to member 33 is provided between each of front ribs 20, 21, 22, 23 and 25 and its corresponding rear rib.
The uppermost portion of the space between each two adjacent-shaft receiving members is formed into a compartment which may be used for receiving weights 4i) by means of partition members 34-38 (incl.). Any suitable paneling (not shown) may be used to enclose the back and the front of the compartments in which weights may be placed. Steel straps 41 extend diagonally across the front and the back of the framework just described and are securely attached thereto to further strengthen the door.
The other three sections of the hanger door are substantially similar in` structure to the one just described. If desired, the four sections may be operated independently, but it is preferred that they be connected together into a unitary Structure so the entire hanger entrance can be more easily opened or closed. The four sections are connected by means of reinforcing stringers attached to the longitudinal stringers located beneath the shaft 14 and bridging adjacent sections of the hanger door framework. Thus the door section on the left side in Figure l is connected to the adjacent section by means of reinforcing Stringer 30a extending about half way along and rigidly attached to the lower side of both Stringer 30 and the Stringer on the adjacent door section corresponding to Stringer 30. Reinforcing stringers 29a and 28a likewise bridge the two sections of the door. Similar reinforcing stringers connect the other sections of the door so as to form a unitary structure.
It is preferred that a lightweight corrugated metal covering be placed on the front of the door and secured to the front ribs by any Suitable means. If desired, a similar covering may -be placed on the rear ribs.
By placing appropriate weights in the compartments along the top of the door, an almost perfectly balanced installation vmay-be obtained so-the door can be opened or closed with unbelievably little energy. It has been found that a 40 foot hanger door constructed according tothe invention may be opened by one person with virtually no effort. If desired, a suitable stop may be Vplaced on the hangerstructure to arrest the movement of the door or a locking mechanism may be used to maintain the door in position.
The framework of the door of this invention may be constructed of Vany suitable building material. 'Beneficial results have been obtained with a wooden framework yfastened together with screws and bolts. However, it will be obvious that a metal framework might be used. While the door described above `is intended to pivot about a xed shaft, it will be obvious that the door framework can be attached to the shaft (as bymcans of dowels passing from the vshaft into the several shaft receiving members) so theshaftrotates-with the door framework. In such an embodiment, the lshaft would be adapted to rotate in bearings mounted in columns 12,;13. If desired, an electric powered drive may be provided to rotate the shaft for the purpose of opening lor closing the door.
