A door (10) made in accordance with the present invention includes a plurality of panels (20) with opposed stiles (24, 25) being positioned at the longitudinal edges of a faceplate (21) of each panel (20) and with opposed rails (26, 27) being positioned at the lateral edges of the faceplate (21) of each panel (20). An insulation assembly (30) includes a sheet of insulation material (31) and a backing sheet (32) which has edges (33) which overhang the lateral edges of the sheet of insulation material (31). The insulation assembly (30) is installed in the door (10) by engaging the stiles (24, 25) with the longitudinal edges of the sheet of insulation material (31) to flex the same until the edges are received in notches (34) formed in the stiles (24, 25). Then the overhanging edges (33) of the backing sheet (32) engage the rails (26, 27) and deform to press the sheet of insulation material (31) against the faceplate (21).
摘要:
A door system including, a door movable between a closed vertical position and an open horizontal position, a cable attached to the door and normally providing a counterbalancing force to the door, the cable extending along a vertical line adjacent the door and being normally substantially taut, and an anti-drop assembly having a pawl pivotally supported on the door and attached to the cable, a stop surface positioned adjacent to the door, and a spring operable to urge the pawl toward engagement with the stop surface, wherein when taut the cable opposes the biasing force of the spring and wherein upon the cable going slack the spring urges the pawl into engagement with the stop surface to decelerate the door.
摘要:
A limited-use appliance is disclosed which has at least one input device for generating an input signal and a controller associated with the input device and receiving the input signal. The controller initiates at least one limited-use function of the appliance upon receipt of the input signal. A test device is maintained by the controller, and has a predetermined criteria which determines whether the input signal should be sent on to the controller or not. A method for pre-installing an appliance is also disclosed and includes the steps of pre-installing an appliance with a controller, wherein the controller operates the appliance in a limited manner. An input device from a group of input devices is associated with the controller, wherein the input device generates an input signal to operate the appliance. And the pre-determined criteria maintained by the controller is tested such that the input signal from the controller is blocked when the pre-determined criteria is met. The appliance is most likely a garage door operator, but it could be any large appliance that is installed prior to the purchase of a home or facility.
摘要:
A door operator and related method of setting custom limits on movable barrier travel, includes a motor for moving the movable barrier between two travel limit positions, an operator for controlling operation of the motor, and a disconnect system coupled between the motor and the operator. The disconnect system is switchable between a connected position and a disconnected position, wherein the motor can engage the operator only when the disconnect system is in the connected position. The operator is connected to a potentiometer for ascertaining movable barrier position, regardless of the position of the disconnect system, and provides position information to the operator. A travel limit is set by placing the disconnect system in the disconnected position and manually moving the door to a desired position whereupon the disconnect system is moved to the connected position so that the operator can detect a positional location to be designated as one of the travel limits. An installation switch may be connected to the operator, wherein the operator determines a custom lower limit or a custom upper limit from the desired position as detected by the potentiometer, wherein actuation of the installation switch establishes the custom limit. An up/down switch may also be connected to the operator. Actuation of the up/down switch during setting of the operational profile and after setting of the custom lower limit sets a custom upper limit.

A door system including a door movable between a closed vertical position and an open horizontal position, a cable interconnected to said door near the bottom thereof, the cable extending along a vertical line adjacent the door and being normally, substantially taut, and an anti-drop assembly having a pawl pivotally supported on the door, a stop surface formed adjacent the door and a spring operable to urge the pawl toward engagement with the stop surface, wherein the pawl is oriented such that it rotates in a plane passing through the cable and placed in contact therewith such that the taut cable opposes the biasing force of the spring, whereby upon the cable going slack, the spring biases the pawl into engagement with the stop surface to decelerate the door.
摘要:
A sectional door (10) and an assembly method for attaching a component (40, 41, 90) to a panel (11) of the sectional door (10) including the steps of fabricating a panel (11) for the sectional door (10), preparing a component (40, 41, 90) for attachment to the panel (11), dispensing a first adhesive (71, 72) on a surface where the panel (11) and the component (40, 41, 90) are to be joined, locating the panel (11) and the component (40, 41, 90) in a predetermined relative attachment position, and dispensing a second adhesive (71, 72) along at least one surface where the panel (11) and the component (40, 41, 90) abut. The sectional door (10) according to the assembly method includes a panel (11) having at least one side with at least a portion being a substantially planar surface (12, 13), a component (40, 41, 90) having at least one engaging surface (65, 66, 87, 88, 91) joined to the planar surface (12, 13), a first adhesive (71, 72) interposed between the planar surface (12, 13) and the engaging surface (65, 66, 87, 88, 91), and a second adhesive (71, 72) disposed along an edge of the engaging surface (65, 66, 87, 88, 91) and the planar surface (12, 13), whereby the second adhesive (71, 72) effects a seal between the panel (11) and the component (40, 41, 90) and imparts structural strength of the component (40, 41, 90) to the panel (11).
摘要:
A system for signaling the position of a movable barrier includes a movable barrier; a motor coupled to the movable barrier for moving the movable barrier between limit positions; a position detection device that monitors the movable barrier to generate a barrier position signal; and an indication device that receives the barrier position signal and indicate a position of the movable barrier relative to the limit positions. The system also includes an operation mechanism for controlling the motor and at least one transmitter device which generates a transmission signal received by the operator mechanism to energize the motor. The system further includes a blocking switch which generates a blocking signal received by the operator mechanism to prevent receipt of a transmission signal from a device other than one associated with the indication device.
