SUPPORTING MEANS FOR FOLDING DOORS Filed June 17, 1963 IN VENTOR.
LEONARD E. JOHNSON. JR
ATTORNEY.
United States Patent 3,206,794 SUPPORTING MEANS FOR FOLDING DOORS Leonard E. Johnson, Jr., R0. Box 114, Elkhart, Ind. Filed June 17, 1963, Ser. No. 288,256 Claims. (Cl. 16-151) The present invention relates to folding doors and more particularly to means for supporting such doors in doorways.
It is conventional practice to support folding doors on a pivot pin fixed to the bottom of the door. This pivot pin is rotatably mounted in a load-carrying pivot bearing which may be mounted on the floor or on a bracket fixed to the door jamb adjacent the bottom of the door. A non-load carrying pivot pin is secured to the top of the door and is journalled in a pivot bearing secured to an overhead track or to the top of the door frame. The door is installed by inserting the top pivot pin in its bearing, raising the door sufiiciently for the bottom pivot to clear its pivot bearing, and then lowering the door until the bottom pivot is disposed in a load engagement with the bottom bearing. Suflicient clearance must be left between the top of the door and the overhead track to permit the door to be raised above the bottom hearing when the door is installed or removed. The space between the top of the door and the overhead is unsightly and requires that extra trim be used to cover it.
The free end of the folding door is usually provided with a guide member or roller at the top thereof which is movable in an overhead track to guide the door and cause it to fold as the door is opened. For proper operation, the top of the doors must be parallel to and spaced a predetermined distance frm the overhead track. It is diflicult to achieve this condition when the door is supported at its pivoted end from the bottom and at its free end from the top.
In the present invention both the pivoted end and free end of the folding doors are suspended from the same overhead track. Since the bottom pivot jamb bracket carries no weight it may be properly located while the door is suspended in place. After the bottom pivot jamb bracket is secured to the doorway adjacent the bottom of the door and the bottom pivot pin disposed in the bracket, further adjustment may be accomplished with the door in place. The latter adjustment may include adjustment in a direction perpendicular to the door jamb commonly called the horizontal adjustment and adjustment in a direction transverse thereto, commonly called the in and out adjustment.
It is an object of the [present invention to provide means for supporting a folding door from a top pivot and providing means for disengaging the bottom pivot, so that the door may be installed or removed without substantial vertical displacement of the door.
It is a further object of the invention to provide a door jamb bracket which is universally adjustable.
These and other objects and advantages of the present invention will become readily apparent from the following detailed description taken in connection with the appended drawing in which:
FIGURE 1 is a front view of a folding door mounted in a doorway on the supporting means of the present invention;
FIGURE 2 is an exploded view of the door jamb bracket shown in FIGURE 1;
FIGURE 3 is a bottom view of the door jamb bracket showing the position of parts in the horizontal extended position;
FIGURE 4 shows the position of parts after a transverse adjustment has been made;
FIGURE 5 shows the position of parts in the horizontal retracted position;
FIGURE 6 shows the bearing arm of the door jamb bracket of FIGURE 2 depressed to its lower limit position; and
FIGURE 7 is a top view of the top pivot bracket shown in FIGURE 1.
Referring now to the drawings, 10 designates a folding door mounted in a doorway 12 having an overhead track 14 to which is secured a top pivot bracket 16 provided with an open ended slot 18 which is disposed to receive the stem 20 of a top pivot 22 which is secured at the top of door 10 by suitable screws 24. Stem 20 of top pivot 22 is provided with an enlarged end portion 26 which is adapted to overlap slot 13. The top pivot 22 when mounted in bracket 16 pivotally supports door 10.
A door jamb bracket 28 is secured to the jamb or side 30 of doorway 12 by suitable screws 32. The vertical mounting plate 34 of bracket 28 is provided with a vertical slot 36 through which one of the screws 32 is adapted to extend and provides means for readily adjusting the jamb bracket vertically. A horizontally extending flange 38 is formed on jamb bracket 28. A longitudinal slot 40 is formed in flange 38 to receive screws 42 and 44 which are adapted to respectively extend through arcuate opening 46 and circular opening 48 formed in a plate 50. Screws 42 and 44 are received in fastener member 52 to clampingly secure plate 50 to flange 38. A stem 54 depends from plate 50 and is provided with an enlarged head or end portion 56. Plate 50 is also provided with a pair of diametrically opposed recesses 58 and 60 which are adapted to respectively receive the turned over end portions 62 and 64 of spaced fingers 66 and 68 formed on horizontally extending arm 70. The spaced fingers 66 and 68 are disposed to straddle or receive stem 54. A resilient means or spring 72 en circles stem 54 and abutts the enlarged head 56 at one end and arm 70 at the other end to resiliently urge arm 70 towards its upper predetermined limit position where it is substantially parallel to plate 50 and flange 38. As best seen in FIGURE 6, arm 70 is pivotally mounted with respect to plate 50 and flange 38 and is movable downwardly into a lower limit position. A nylon annular bearing member 74 is formed on arm 70 and is adapted to journal a bottom pivot pin 76 when the arm is in its upper limit position as shown in FIGURE 1. The bottom pivot pin 76 is secured to the bottom of door 10 by suitable screws 78. When the arm 70 is depressed to its lower limit position as shown in FIGURE 5 the bearing is positioned below the end pivot pin 76 so as to be out of engagement therewith.
The screws 42 and 44 may be loosened to permit the plate 50 and arm 70 to be moved back and forth in a horizontal direction perpendicular to the door jamb 30. The parts are shown in their extreme extended position in FIGURE 3 and in the extreme retracted position in FIGURE 5.
With screws 42 and 44 loosened the plate 50 and arm 70 may be moved in a transverse in or out direction within the limits of the arcuate slot 46. The position of parts shown in FIGURE 4 illustrates the extreme in adjustment.
From the above description, it will be readily apparent that the door may be easily suspended from the top pivot bracket and secured for proper operation by the door jamb bracket.
