Abstract

1355514 Door operating mechanism J A FAWDRY 17 July 1972 [17 April 1971] 9727/71 Heading E2M A door operating mechanism employs a screw and nut mechanism in which a nut is rotated by an electric motor and displaces a lead screw which is pivotally linked to a door attachment member. In the arrangement shown garage doors 2, 3 are connected to lead screw 8 by links 5 pivoted at 4 to door attachment members 3 and at 7 to a cross arm 6. A pulley 9 having an internally threaded portion 9A constitutes the nut and is connected to the pulley 16 of an electric motor 14 by a transmission belt 17. Plates 10 and 11 attached to a roof joist 12 prevent axial movement of the nut and provide support for the motor. The screw is prevented from rotating in the example shown by the link mechanism 5, 6; alternatively a projection on plates 10, 11 could engage a longitudinal groove in the screw. Elements 20, 21 are adjustably mounted on the screw and actuate limit switches 18, 19. The operating switch for the motor may be of various types: a manually operable key switch mounted on the door, a pressure or photo-electric switch operated by the vehicle, or a switch detecting a sound, light or magnetic signal transmitted by vehicle or driver. The edges of the doors may incorporate safety switches to prevent the doors closing on persons or objects, additionally the hinge pins 4 may be of soft metal so as to shear in the event of obstruction. The mechanism may be employed in single hinged doors or in single doors of the 'up and over' type by connecting the lead screw to the upper edge of the door by a single pivoted link.
