Abstract:
An operator and related method for adjusting an internal force setting for a motorized garage door operator is disclosed. The operator checks for the presence of a secondary entrapment safety feature and automatically increases a force threshold setting from a first value to a second value if the secondary entrapment safety feature is detected. If the safety feature is not detected or it is later disconnected, then the operator automatically sets the force threshold to a more sensitive value.
Abstract:
A track assembly for an overhead door (10) includes a generally vertically positionable track segment (14) and a generally horizontally positionable track segment (15). The track segment (14) includes a curvilinear portion (17) at one end thereof which is joined to a curvilinear portion (21) of the track segment (15) by a bracket (30). The curvilinear portion (17) of the track segment (14) has a smaller radius of curvature than the curvilinear portion (21) of the track segment (15). The bracket (30) has tabs (40) which are received in a slot aperture (42) in the curvilinear portion (17) to attach it to the bracket (30), and the bracket (30) has a lug (41) which is received in a slot (44) in the curvilinear portion (21) to attach it to the bracket (30).
Abstract:
A system (10) for covering an opening (11) in a structure (12) includes a sheet (13) of flexible material having opposed side edges (16, 17). A thickened area (18) and a pocket (20) are formed at the side edges (16, 17). A plurality of spaced apertures (22) extend through the thickened area (18), and a rope (21) is positioned in the pocket (20). A grommet assembly (23) is positioned in each of the apertures (22) to reinforce the apertures (22). A plurality of fasteners (28) are carried by the structure (12) and are spaced so that they can extend through the apertures (22). Wing nuts (34) received by the fasteners (28) hold the sheet (13) on the structure (12) and over the opening (11).
Abstract:
A sectional door including, a plurality of panels pivotally joined to each other, the panels including a facer having a front surface, a first joint member and a second joint member extending rearwardly of the facer, a pair of end stiles received at lateral extremities of the panels and placed in supporting relation thereto, the stiles having a recess adjacent one of the joint member, a hinge receiver located adjacent the recess and a hinge pivotally coupled to one of the panels at the hinge receiver and fastened to another of the panels at the end stile, wherein the recess provides a clearance for pivoting movement of the hinge and the storage or stowage of door components.
Abstract:
An upwardly acting sectional door (24), including a plurality of panels (40), body portions (50) of the panels constructed of a flexible polymeric material and having a front surface (55), a cladding (80) covering the front surface of the body portions and having hooks (83, 84) at the upper and lower edges thereof, a hinge member (51) at an edge of the body portion operatively engaging the hooks of adjacent of the panels to provide relative pivotal motion between adjacent panels. Another embodiment is an upwardly acting sectional pan door (224) including, a plurality of panels (240), facers (250) of the panels defining a front surface of the door and having cooperatively engaging couplers (270) at the upper and lower edges thereof; stiles (280) at the ends of the facers receiving and attached to the facers, and hinge assemblies (290) located at the end stiles to provide relative pivotal motion between the stiles and the couplers of adjacent panels.

Abstract:
A modifiable transmitter is used with an operator to control a position of a barrier. The operator includes a controller for comparing radio frequency transmissions received with stored serial numbers so that the controller can move the barrier when a radio frequency transmission matches any one of the stored serial numbers. The transmitter includes a housing that carries an encoder. A function button is carried by the housing, wherein actuation of the button generates in a non-standard way a new serial number that can be learned by the controller to allow the modifiable transmitter to move the barrier by emitting the radio frequency transmission. A restricted access may also be activated to generate a new serial number.
Abstract:
A method of aligning a door operating system for operating an upwardly acting door including an operator that directly interrelates with a counterbalance assembly in the door operating system to move the door, where the operator is at least partially supported on the counterbalance assembly, loosely attaching the operator to a header adjacent the door, and, moving the door from a closed position to an open position and returning the door to the closed position to achieve alignment. Once aligned, the operator is securely attached to the header to maintain the system's alignment.
Abstract:
A sectional door D having a plurality of panels (35), a first hinge leaf (44) formed on one edge of a panel and a second hinge leaf (42) formed on a second edge of the panel, wherein first and second hinge leaves on adjacent panels interrelate to form a hinge pivotally joining the panels, and a strengthening member (50) having a body portion (51) adapted to capture the hinge leaves and attachable to the panels near at least one of the first hinge leaf and the second hinge leaf.
Abstract:
An operator system and related methods (10) for sensing forces on a movable barrier (12) includes a motor (52), a trolley (30), and a trolley arm (34) having a first end slidably supported by the trolley (38) and a second end coupled to the movable barrier. The motor moves the trolley arm which in turn moves the movable barrier. A force detection mechanism (68) is coupled to the motor to determine a first component force value applied by the motor. A controller (54) receives the first component force value and determines a detected force value by scaling the first component force value with a second component force value derived from an angular position of the trolley arm's first end with respect to the trolley. The angular position of the trolley arm may be fixed or variable. An angle potentiometer (72) is coupled to the trolley arm to generate an angle signal for use as the second component force value when the trolley arm's angular position is allowed to vary.
