j p Wm W r Mm 2 M l United States Patent 3,169,574 FLEXIBLE DOOR Walter D. Behlen, Columbus, Nebr., assignor to Behlen Manufacturing Company, Inc., Columbus, Nebn, a corporation of Nebraska Filed July 6, 1962, Ser. No. 207,969 2 Claims. (Cl. 160-363) This invention relates to large opening doors for aircraft hangars, industrial warehouses, and the like, and more particularly to a single sheet flexible metal sliding door for the same. 1

One of the problems encountered in previous doors of this magnitude is that they must be mounted on rails that extend in a straight line from the sides of the door opening and thus create an obstruction hazard at each side and end of the building.

Another problem encountered with previous sliding doors is that they are precariously subject to wind damage.

Still another problem is that they are heavy and difficult to operate.

A further problem is that they aredifiicult to transport and erect.

Still another problem is that they are expensive to manufacture and install.

Therefore, one of the principal objects of my invention is to provide a large magnitude single sheet flexible sliding door that can be mounted on rails that closely follow the corners of the building utilizing the same.

Another object of this invention is to provide a large magnitude single sheet flexible sliding door that eliminates the previous obstruction hazard at each facade corner of the building utilizing the same.

A still further object of my invention is to provide a large magnitude single sheet flexible sliding door that is substantially impervious to wind and like damage.

A still further object of this invention is to provide a large magnitude single sheet flexible sliding door that is relatively light in weight.

A still further object of my invention is to provide a large magnitude single sheet flexible sliding door that is easy to operate.

A still further object of this invention is to provide a single sheet flexible sliding door that is relatively easy to transport and erect.

A still further object of my invention is to provide a large magnitude single sheet flexible sliding door that is capable of being erected so as to slide either horizontally or vertically.

Still further objects of this invention are to provide a large magnitude single sheet flexible sliding door that is economical in manufacture, durable in use, and refined in appearance.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, arrangements, and combination, of the various parts of the device, whereby the objects contemplated are attained as hereinafter more fully set forth, specifically pointed out in my claims, and illustrated in the accompanying drawings, in which:

FIG. 1 is a side view of the lower end portion of my flexible door showing its mounting means,

FIG. 2 is a top view of a portion of my door and more fully illustrates its mounting means,

FIG. 3 is a reduced inner side View of my door, and

FIG. 4 is a reduced top plan view of my door.

In these drawings I have used the numeral 19 to generally designate an aircraft hangar, building, barn, garage, warehouse, or the like, having a floor 12, a facade wall 14, and side wall 16, and a door opening 17. It is to such building structures and their entrances that I direct my door and which I will now describe in detail.

The numeral 22 generally designates a support and guide rail disposed on the floor 12 and horizontally ex tending in closely spaced parallel relation to the inner surface of the facade 14, door opening 17, and thence curving at the front corner of the building so as to extend in closely spaced parallel relation to the inner surface of the side wall 16, as shown in FIG. 4.

The numeral 24 generally designates a similar guide rail operatively located above the entrance 20 near the top periphery of the inner surface of the facade wall 14. door opening 17, and then curved at the building corner to extend at the top inside of the wall 16. The rail 24 extends horizontally in substantially superimposed spaced parallel relation to the rail 22. It is supported to the frame of the building, as shown in FIG. 3.

The numeral 26 generally designates my flexible sliding door which is constructed of an operatively single sheet of corrugated metal, or the like, and which operatively extends between and in communication with the rails 22 and 24. The door 26 has major parallel corrugations 28 that protrude outwardly and alternate inwardly. These major alternate corrugations are, of course, parallel to each other and extend transverse to the rails 22 and The numeral 32 generally designates a plurality of minor corrugations that are parallel to the major corrugations, and may form a part of the major corrugations, as shown in FIG. 4. The flexible corrugated door 26 is for all intents and purposes a single sheet of corrugated material. This single sheet, however, may consist of several secured together panels.

The numeral 34 generally designates a support dolly disposed near the bottom inner side end of each alternate corrugation 28 and in operative contact with the rail 22. These support dollies are each comprised of a base plate 36 which is suitably secured to the inner side of its respective corrugations 28, such as by bolts 38 and 40 extending through the flexible door 26, as shown in FIG. 1. The numeral 42 generally. designates an obtuse angled arm pivotally disposed on the bolt 40 in the area of its angle in such a manner that the plane of elongation of the arm 42 is parallel to and movably substantially against the presenting surface of the base plate 36. The obtuse angle of the arm 42 is located above and to one side of the bolt 40. The numeral 44- generally designates a second arm means similar to the arm 42 that is also pivotally disposed on the bolt 40 and slidably against the arm 42. However, the arm 44 has its obtuse angle located above and to the opposite side of the bolt 4%) from that of the arm 42, as best shown in FIG. 1. The opposed spaced apart top ends of the arms 42 and 44 are yieldingly drawn together by means of the coil spring 46 which is secured thereto and communicates therebetween.

The numerals 47 and 48 generally designate dolly wheels that respectively are operatively rotatably secured to the opposed bottom ends of the arms 42 and 44 and are disposed in a vertical plane substantially parallel to that of the base plate 36. The dolly wheels 47 and 48 are each peripherally grooved, as shown in FIG. 2, to be in contact with and roll on the rail 22.

The numeral 50 generally designates a guide dolly disposed near the bottom inner edge of each of the corrugations 28 that are alternate to the corrugations 28 which have support dollies 34 secured thereto. The guide dolly 50 is comprised of a base plate. 52 that is secured near the bottom inner side edge of its respective corrugation 28 by bolt means 53 as shown in FIG. 1. Integral with and extending horizontally outwardly from the bottom of the base plate 52 is the triangular plate 54. This plate 54 is located over the rail 22 in such a manner that its two base corners are on one side of the rail 22 and its apex is on the other side. The numeral 56 generally designates a horizontal guide wheel rotatably secured to and below each corner of the triangular plate 54. The two base corner wheels are, of course, rotatably in contact with the outer side of the rail 22 and the apex wheel is in rotatable contact with the inner side of the rail 22, as shown in FIG. 2. If desired, a plurality of both major and minor corrugations to impart to the door sheet a relatively great tortional strength as well as longitudinal flexibility. The door will withstand winds of high velocity. The entire door unit can be loosely rolled up into a column and easily transported to the site where it is to be used, unrolled, and installed as a unit. Experience has shown that my door is excellent for closing large open door areas, such as airplane hangars. In the drawings I show my door as a horizontal one, but it has proven itself as a vertical door by simply vertically installing the rails 22 and 24 at each side of the open door entrance and then curving them at their tops to extend horizontally at the ceiling of the building. The transverse relationship of the corrugations relative to the rails is retained but in such a vertical door, the corrugations will run horizontally. In such vertical doors, it is recommended that the spaced apart dollies 34 and 50 be used at each side edge of the flexible door sheet 26. With such a vertical slidable door, the door sheet 26 will flex at the top of the door opening to assume a horizontal condition near the ceiling of the building. To close such a vertical door, it is merely necessary to pull it outwardly and then downwardly. If my door is to be horizontally operated, to open the door it is merely necessary to push it horizontally from the door opening and it will curve to assume a position adjacent the inside of the building wall 16. To close the open doorway, the flexible door sheet is merely drawn horizontally across the door opening. Obviously, the corrugated door will not flex against the longitudinal lengths of the corrugations. Therefore, the coil springs 46 will not longitudinally bend the corrugations but lth springs 46 will yieldingly hold the wheels 47 and 48 in contact with the rail supports and thereby automatically compensate for any variations, irregularities, or like, in the installed unit or for any variations, irregularities or like that might develop after extended usage.

Some changes may be made in the construction and arrangement of my flexible door without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents which may be be reasonably included within their scope.

I claim: 1. In a sliding one sheet door means, comprising, in
