Patented Nov. 15, 1932 HERBERT RALPH EKLUND, OF ROCKFORD, ILLINOIS OVERHEAD noon Application filed May 12,
This invention relates to doors adapted for garages or other types of buildings and has for the primary object, the provision of a device of the above stated character which may 5 be easily and quickly moved to occupy either a closed or an opened position and when in an opened position is adapted to occupy a place within the building and overhead or substantially in parallelism with the ceiling of the building, so that the entrance of the latter will not be obstructed by the door.
Another object of this invention is the provision of a plurality of sections constituting the door and attached together by hinges of novel construction which also slidably engage the door tracks, whereby the. sections are eificiently connected together and to the tracks so that the door'may be easily and quickly moved to opened or closed positions by having sliding relation to the tracks.
A further object of this invention is the provision of a door of the above stated character which will be' simple, durable and efiicient and which may be manufactured and sold at a comparatively low cost.
With these and other obiects .in view. this invention consistsin certain novel features of construction, combination and arrangement of parts, to be hereinafter more fully described and claimed.
For a complete understanding of my invention. reference is to be had to the following description and accompanying drawings, in which Figure 1 isa fragmentary vertical section al view illustrating a door mounted on tracks associated with the entrance and ceiling of a building.
Figure 2 is a fragmentary sectional view Figure 3 is an enlarged fragmentary sec tional view illustrating the hinge construction between a pair of sections of the door.
Figure 4 is a sectional view taken on the line H of Figure 2.
Referring in-detail to the drawings, the numeral 1 indicates a building construction having a doorway or entrance 2 with channel tracks 3 associated with the vertical edges thereof and as shown in Figure 1 the tracks 1931. Serial N0. 536,870.
are curved to extend in substantial parallelism with the ceiling as shown at 4. The tracks include vertical portions and horizontal portions connected by arcuate shaped portions, and the arcuate shaped portions and 65'. horizontal portions are supported to the building byhangers 5. i
A door 6 is slidably mounted in the tracks and when in doorway closing position is disposed in the vertical portions of the tracks and when desiring to open the doorway, the door is moved upwardly and into a horizontal position substantially in parallelism with the ceiling thus fully opening the doorway.
The door 6 is constructed from metal, wood or any other material suitable for the purpose and includes a plurality of sections 7 that have secured thereto metallic covering 8 which projects beyond each longitudinal edge of the sections to provide extensions 9 7 and 10, respectively. The extension 9 is bent upon itself to form an overlapping portion 11 o and then bent into substantially cylindrical shape to form .a hinged bearing 12. The extension 10 is bent into substantially cylindrical shape to provide the bearing portion 13 fitting within the bearing portion 12 to form a hinged connection.
The bearing portion 13 has mounted therein a tubular member 14 the ends of which receive shafts 14 carrying anti-friction rollers 15 that are received within the channel tracks 3 thus slidably supporting the device to the tracks. i
From the foregoing description taken in connection with the accompanying drawings, it will be note that the sections are efficiently hinged together so that the door when moving from ne position toanother on the tracks will slide relative to said tracks without binding or becoming caught by undue b nding action between itself and the tracks. The door when in a vertical position for the purpose of closing the entranceway 2, the extensions 9 overlap the adjacent extensions 10 to provide a water-proof connection between the sections and which will permit said sections to easily swing relative to each other during the door moving from one of its posi-. d tions to its other position. i m
While I have shown and described the preferred embodiment of my Invention, it will be,
understood that minor changes in construe tion, combination and arrangement of parts may be made without departing from the spirit and scope of m invention, as claimed. Having thus descri ed my invention what I claim is:
A door comprisin a plurality of relatively spaced panels, meta lic strips secured to the panels and projecting beyond the edges thereof to provide extensions having overlapped relation and one extension of each strip bent upon itself and curved into cylindrical formation to form a hinge section, the other extension of each strip curved to provide a cylindrical hinge section fitting in the hinge section of the'adglacent extension, tubular sleeves mounted int e hinge sections, and track engaging shafts projecting from the ends of the sleeves. v
In testimon whereof I afiix my signature.
