DOOR AND OPERATING MECHANISM THEREFOR.
Application filed December 1, 1922. Serial No. 604,281.
This invention relates more particularly to a vertically folding door and has for ltS principal object to provide means whereby the closing of the door at the bottom is tight. Other objects and advantages will appear from the following disclosure.
The invention is embodied in the example herein shown and described, the features of noi'elty being finally claimed.
In the accompanying drawings- Figure 1 is mainly a front elevation of a folding door equipped with my invention, details of the couuterbalan'cing means being shown in section.
Fig. 2 is a vertical section on the line IIII Fig. 1.
Figs. 3 and 4 are vertical sections showing how the opening of the door is initiated and the relative positions of the parts.
In the views 5, 5 designate respectively upper and lower door sections which sections are hinged together at 6. The-upper door section is slidingly' hinged upon pins 7 on end brackets 8, 8*, by means of hinging members 9, said hinging members being formed with slot-s 9" so as to allow vertical play of the upper section in the initial opening and the final closing movements of the door a hereinafter set forth.
The means for raising the door sections includes spiral cone. pulleys 10 and 10 secured to the ends of shaft parts. where they protrude beyond the end brackets and cords 11 connected to the lower corners of the lower door section, the connection of the cords with the cone pulleys being at the larger ends thereof so that the pull of the cords increases as the door sections are raised and diminishes as the sections are lowered. \Vhere the door is of large dimensions and heavy the pull of the cords is augmented by a coil spring 12 attached at one end of the intermediate hollow shaft part 13 and at the other to the hub 14' of a wheel 15, said wheel being adapted to be locked in adjusted position by a pin 16 inserted througha projection 17 on the end bracket 8 and any one of several holes in the. rim of the Wheel 15. By turning the wheel in the proper direction the spring can be tightened to place under tension the shaft 13 with'its two opposite end parts pinned thereto and carrying the cone pulleys so that the pull of the pulleys shall in a suitable measure counterbalance the weight of the sections and augment the manual effort required to raise them.
In practice the right hand shaft part beyond the bracket has secured to it a large gear 18 engaged by a small gear 19 mounted on the end bracket, the shaft of said small gear being provided with a sprocket wheel 20 carrying a chain 21 hanging therefrom. By the operation of said chain the door may be raised or lowered.
The lower door section 5 is shown as provided near the chain with a. handle 22 so that the door can be conveniently initially flexed at its hinges as shown in Fig. 3 to permit effective action of the draft of the cords to raise the door. This same handle can be used for shoving the door sections into vertical coincidence for closing the door. In cross: section the door members are elongated rectangles hence when the door is flexed atthe hinge 6 as shown in Fig. 4 the upper section is slightly raised because the sum of the diagonals of the two rectangles is greater than the sum of a pair of the sides, and conversely when the door is moved to completely closed posit-ion the upper door section falls the lower edge of the lower section then resting squarely upon or very close to the floor. The upper door section in these movements moves in the direction of its plane.
The lower door section at its lower corners is provided with rollers 23 journaled thereto as shown to travel on the faces of the usual tracks 24 for such doors. These rollers can be so located that when the door is flexed as upper section slidingly engaging said pins,
said connection permitting swmging movement of said up r section as well as planemeans on the building engaged by said pivwise movement t ereof in all positions thereoting members permitting planewise move of. ment of said upper section in all positions 10 2. A door for a building including upper thereof. 6 and lower door sections hinged together,
