DOOR OPERATING MECHANISM Filed Dec. 2, 1946 2 Sheets-Sheet l FIGJ.

INVENTOR.

MAHLON M. MATCH ETT BY M M /m ATTORNEYS Patented Feb. 6, 1951 D OR OPERATING MECHANISM Mahlon M. Matchett, Detroit, Mich, assignor, by mesne assignments, to McKee Door Company, Aurora, 111., a corporation of Illinois Application December 2, 1946, Serial No. 713,585

7 Claims.

The present invention relates to door operating mechanism and more particularly to mechanism adapted to operate an overhead tilting door of the type employed on garages.

In accordance with the present invention, motor means are mounted to a stationary part of the garage adjacent the door and are connected to an elongated screw. Secured to the door is a nut threaded to the screw. Upon rotation of this screw the nut is moved along the screw, thus imparting tilting motionto the door in an upward or downward direction depending upon the direction of rotation of the screw.

It is an object of the present invention to provide improved and simplified means for operating an overhead tilting door;

It is a further object of the present inventionto provide screw actuated means for tilting an overhead door in a smooth positive manner.

It is a further object of the present invention to provide door operating mechanism including a motor and mounting means for the motor which permit its use at either side of the door opening.

Other objects and features of the inventionwill become apparent as the description proceeds, especially when taken in conjunction with the accompanying drawings, wherein:

Figure l is a side elevation of the door operating mechanism;

Figure 2 is a plan view of the door operating mechanism;

Figure 3 is an end elevationof the screw housing;

Figure 4 is a front elevation of the screw hous- Figure 5 is an end elevation of a pivotal housing support; and

Figure 6 is a frontelevation of the pivotal housing support.

Referring now to the drawings, the overhead operating arms 24: and 25, respectively. Mounted onthe screw supporting block 2| is an electric.

motor 33 which drives a small pulley 3i. Rigidly connected to the screw 20 is a large pulley 32 whichis adapted to. be driven. from the motor pul- Icy-3.1. byja V'-belt.or' thelike 33L Extending laterally from the door I0 and above the hinge H is an actuating arm 40.

As best seen in FigureZ, the arm 40 terminates at its free end in a reversely bent, U-shaped portion 4|, the arms of which are provided with a pivot pin 42. 'Secured' to the pivot pin 42 is a pivotal yoke 4'3'having arms 44 and 45/ A nut 46' is pivotally supported between the arms 44 and- 45 and is in threaded engagement with the screw 20'. The actuating arm 40 is rigidly connected to the door ID by a plurality of fastening elements indicated'in Figure I at 41.

The block 2| is mounted for swinging movement in a verticalv plane by a pivotal bracket 50 which is carried by a pivot support 5i The support 51 is rigidly secured to a suitable rigidpar-t' of the garage structure adjacent the side of the door. Inthe present instance the support is illustrated as secured to a 2 x 6 spacer 52 extending between upright studdings 53. It will be appreciated, however, that any suitable rigid support may be providedfor the support 5|. As illustrated, the bracket 50. is provided with a pair of arms 55 which span an outwardly projectingportion 56 of the support 5|, and is pivotally connected thereto by a. pivot pin 51.

With the foregoing description in mind, it will be observed that rotation of the screw 20 in a direction to feed the nut 46 upwardly along the" screw will result in downward swinging motion of the garage door and corresponding upward swinging motion of its upper end and the actuating arm 40. The door Ill may be swung from a horizontal to a vertical positiomorif preferred its" closed position may be somewhat inclined from the vertical. Assuming, however, that the door "I swings between horizontal and vertical positions, there are indicated at 20" and 46' the positions of the screw and'nut,respectively,.when the door operating mechanism will be adaptable for" mounting. at either. side of the door or. between. the. dooropenings in. the case-of double garages,.v

structure. has been provided for mounting the motor. 30. andthe block 21- in difierent positions. relative to the bracket 50. This structure is best illustrated in Figures 3, 4,.5 and 6 taken in conjunctionwith the. assembly illustratedin Figure 1.

Theb'lock 24 is; provided witha flange lillhaviiigv openings Bl therein to which the motor 30 is secured by fastening elements indicated at 62 in Figure 1. The arms 24 and 25 are provided with openings 63 and 64, respectively, in which the screw 20 is journalled, bushings 66 being provided in the openings. The arm 25 is in addition provided with four equally spaced tapped recesses 65.

The pivoted bracket 50 is provided with a short cylindrical stud 1c of a size to be received within the opening 64 in the arm 25. It will be appreciated that the lower end of the screw shaft 20 terminates short of the end of the opening 64 so as to leave room therein for the reception of the centering stud 1D. The stud 10 thus serves as a centering and positioning means for assuring proper location of the motor 3!] with respect to the pulley 32. The bracket 50 is in addition provided with a pair of openings ll adapted to receive screws I2 for securing the screw housing 2i thereto. It will be observed that the openings 1! may be registered with any two opposite tapped openings 65 in the screw housing 2|, and accordingly the block 2! may be rigidly secured to the bracket 50 in any one of four positions of adjustment stepped at 90 about the axis of the screw 20. This permits the motor to be positioned at any side of the screw 20 as circumstances require so that the entire structure may be mounted in a relatively restricted space.

The pulleys 3| and 32 are removable from the motor and screw 20, respectively, so that pulleys of different size may be substituted therefor to effect desired changes in driving ratio. Thus, for example, if the door is relatively heavy the driving ratio may be reduced so that its actuation will be relatively slow, whereas if the door I is of a relatively light construction the driving ratio may be increased so that actuation of the door is relatively rapid.

While there is illustrated and described a single preferred embodiment of the. improved door operating mechanism, it will be understood that this full and complete illustration and de scription has been given merely to enable those skilled in the art to practice the invention, the scope of which is indicated by the appended claims.
