Application August 12, 1944, Serial No. 549,228
Claims.
This invention relates to rolling doors, of the type comprising a flexible curtain formed of a number of sections interconnected for relative hinged movement and adapted to be wound upon a rotatable drum suitably located at the head of the doorway. The invention is specifically directed to the provision of a rolling door of the aforementioned character adapted for use in buildings, industrial structures, garages, and the like, which comprises a flexible curtain incorporating windows suitably arranged therein to permit viewing of the interior of the building to which the rolling door is applied and illumination of the same.
An object of the invention is to provide an improved construction for a rolling door of the type aforementioned, wherein a plurality of windows are provided at spaced intervals along the length of the flexible curtain, and the hingedly interconnected sections forming the flexible curtain are so arranged as to permit of the easy winding thereof upon a suitable non-circular rotatable drum.
Another object of the invention is to provide a flexible curtain comprising alternate rigid window-embodying sections and interconnecting sections, the structure bein such that, when the curtain is wound upon a non-circular drum, the window-embodying sections will form series of superimposed parallel units.
A further object of the invention is to provide a rolling door construction comprising a polygonal winding drum and a flexible curtain incorporating window-embodying sections of uniform width interconnected by sections of different width, whereby, in the winding of the curtain upon the drum, all the sections of the curtain will dispose themselves in parallel relation to sides of the polygonal drum.
These and other related objects will become apparent by the following description of a preferred embodiment of the invention illustrated in the drawing, wherein:
Fig. 1 is a side elevational view of a rolling door according to the invention, illustrating the structure of the flexible curtain forming part of the door and the arrangement of the sections of the curtain upon the drum.
Fig. 2 is a front elevation of the structure of Fig. 1.
Fig. 3 is a perspective view of one of the window-embodying sections of the curtain.
Fig. 4 is a vertical section, on line 4-4 of Fig. 3, illustrating the structure of a window-embodying section.
Referring now in detail to the drawing, Ill indicates a counterbalanced rotatable shaft of the kind usually provided in rolling door constructions, which is suitably supported at the head of the doorway and carries, for rotation therewith, a drum 12 upon which a flexible door or curtain may be wound, the drum being, in the embodiment illustrated, hexagonal in cross-section.
The door or curtain consists of a number of metal sections the length whereof is substantially equal to the length of the winding drum l2, and which are hingedly interconnected at their ends to render the curtain articulated and adapted to be wound upon said drum. Speciflcally, the curtain consists of a number of rigid window-embodying sections or units l6 and a number of connecting sections l8 alternate with the units IS in the manner and for the purpose that will hereafter be described.
The window-embodying units l6, which are all of uniform width, as shown in Fig. 1, comprise a flat portion 2|] formed at its ends with oppositely coiled portions 2!, 22. As will be observed, said flat portion 20 is substantially equal in width to the longer sides 23 of the polygonal drum l2, and is provided with a plurality of identical openings or windows 24, uniformly spaced from each other along said portion 20. Frames 25, secured to the flat portion in any suitable manner, are provided for mounting glass panes 26 in juxtaposition to the windows 24. In the embodiment illustrated, there are shown four rectangular windows 24 and associated frame and glass panes for each section I6; it will however be understood that the number and shape of the windows and associated elements may be varied, as desired.
The connecting sections I8, alternate with the sections i6, are equal in length to these latter, and are likewise formed with oppositely coiled portions 28, 29 engaging the coiled portions of adjacent window-embodying units and adapted to form with these latter hinge members permitting relative angular movement of the various sections, as required for the winding of the curtain upon the drum. Preferably, said connecting sections I8 are rigid and have a flat wall intermediate the coiled portions thereof similarly to the window-embodying units IE, but they may be made, if desired, of substantially flexible corrugated metal sheet. The width of the sections I6, however, is not uniform throughout the length of the curtain, but increases from the top to the bottom of the curtain, in the manner that will be described, for the purpose of permitting the window-embodying units 16 to dispose themselves in groups of units parallel to sides of the polygonal drum l2, when the curtain is Wound upon the drum, as will hereafter become apparent. The curtain is formed, throughout its length, of alternate units I6 and sections l8, though the Windows may be omitted in certain of the units located near the top and the bottom of the curtain, for obvious reasons, the structure remaining otherwise unchanged.
The curtain is secured, at one end thereof, to the drum l2 in any suitable manner, as by means of an initial short link 30 riveted or bolted to the drum, as shown at 3|. Assuming that the first hinged or free section of the curtain is to be one of the units 16, the link 30 is fastened to one of the short sides 32 of the polygonal drum l2 in such a position that the flat portion 20 of the unit is is superimposed to the adjacent long side 23 of the drum, while the coiled portions of the unit project laterally thereof. Since the curtain is formed of alternate units I6 and sections I8, the next short side 32 of the drum will have superimposed thereon the first section l8, which is made substantially equal in width to said short side 32 whereby the second unit i6 is allowed to overlie, with its flat portion 20, the following long side 23 of the drum, in the manner hereinbefore described.
As can be seen in Fig. l, the second section (8 1 is identical to the first, but the next section following the third unit [6 is of greater width to permit the adjacent unit IE to superimpose itself to the first unit and to assume a position in parallel relation to this latter and to the underlying side of the drum. As will therefore be apparent, in order to have series of alined units I6 superimposed upon sides of the drum in parallel relation thereto, the width of the sections 18 isincreased with each winding of the curtain upon the drum, that is in proportion to the increase in the distance of the sections from the axis of the drum,. or, in other words, for each three alternate units I6.- and sections [8 there is an increase in the width of these latter.
The structure formed in this manner permits to provide series of windows incorporated in rigid units so that glass panes may be associated with the windows Without danger of breakage in the operation of the door, requires a minimum of space for the Winding of the curtain and insures a smooth and easy operation of the door due to the advantageous arrangement of the sections of the curtain and associated drum.
While I have described my invention substantially with reference to a preferred embodiment thereof, it is to be understood that changes and modifications may be made in the structure described and illustrated in the drawing without departing from the spirit of the invention or ex- .ceedihg the scope of the claims.
I claim:
