Abstract:
A drive system is provided for a moveable barrier, such as a garage door, that limits unauthorized shifting thereof. The drive system includes a flexible actuator for raising and lowering the door. The flexible actuator is tensioned with a biasing mechanism to minimize actuator throw, and a stop assembly of the biasing mechanism limits unauthorized travel of the garage door from the closed position by a predetermined amount that is sufficiently small so as to keep intruders out of the garage. The flexible actuator may for example, be a cable, a belt or a chain.
Abstract:
The present device has a wire drum connected to a sliding door through a wire cable and being rotated by the power of a motor, an electromagnetic brake which applies braking to the wire drum using a solenoid as the driving source, and a switch transistor which sends electricity to the solenoid when being turned on by a Hi signal from the output port of a controller. The interval between the solenoid and the switch transistor is connected through a line where the voltage level is raised when the switch transistor is turned off and the voltage level is lowered when the switch transistor is turned on. The line is connected through a failure detecting circuit to the input port of the controller.
Abstract:
A door panel assembly includes a panel with a window lifting mechanism mounted on one side and a power mechanism mounted on an opposite side. The panel has a first alignment feature for aligning the window lifting mechanism relative to the panel and a second alignment feature for aligning the power mechanism relative to the panel. The first and second alignment features facilitate alignment of the window regulator and the power mechanism to each other. Further, the first and second alignment features allow initial assembly of one of the window regulator or power mechanism components to the panel with a subsequent assembly of the remaining component to the, panel without having to hold the first component in place.
Abstract:
A vehicle door is assembled by immobilizing a cable drum with a wedge and then coupling the wedged drum to a drive member. A cable is wound onto the drum either before or after the positioning of the wedge. A drive member is then coupled to the wedged drum. After coupling, the drive member is fixed to the vehicle door. The window guide structure can also be inserted between the inner panel and an outer panel of the vehicle door. The wedge can be removed from the window guide structure, or alternately, the wedge can be fixed to the window guide structure. Alternately, the method further includes the steps of placing the cable in deflection pulleys before the steps of positioning the wedge and winding the cable. The drive member is pivotally mounted to the inner panel about an axis offset relative to the rotational axis of the drum, and the cable is tensioned by pivoting the drive member about the offset axis. The drive member is then fixed to the inner panel of the vehicle door. Essentially, a pre-assembled intermediate window drive is created that facilitates mounting to a vehicle door.
Abstract:
A control method of sliding a vehicle door by a powered sliding device with a clutch mechanism comprises the steps of stopping a motor in a state that a rotation of a wire drum is restricted by an auxiliary brake when the slide door reaches at a desired semi-open position; displacing the clutch mechanism into a second coupled state by the motor while the auxiliary brake is actuated; releasing the restriction by the auxiliary brake when a predetermined time has elapsed.
Abstract:
A garage door security device for use with a GDOS in a garage to prevent unauthorized access to the garage includes a switch actuator device for actuating and de-actuating an electric current, a female socket operably connected to the switch actuator and for receiving a male plug of the GDOS, a male plug operably connected to the switch actuator and configured to be received within a conventional electric outlet, and wherein the switch actuator includes on/off capabilities to allow or prevent electric current to flow from the electric outlet to the GDOS.
Abstract:
A system assembles an apparatus for activating a window on a fixed support. The apparatus includes a drum housing drum cover which has a cover body which is capable of being secured on the fixed support by a first securing member. The cover body includes lugs which block the drum in the drum cover. The system further includes a motor assembly for driving the drum in rotation. The motor assembly includes a principle body which is capable of being secured on the cover body by a second securing member.
Abstract:
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.
Abstract:
The present invention provides a vehicle door, wherein a drive unit for raising and lowering a glass plate is constructed so that a plurality of pulleys across which wires are laid are provided at upper and lower sides of a base panel, the glass plate is moved up and down by driving the wires, the glass plate is prevented from moving in a vehicle inward direction when the door is closed, wire fixing portions are prevented from being damaged by great upward and downward stroke movements of the glass plate, and furthermore, the wires are prevented from slackening when the wires are driven and stopped. This is realized by providing a supporting rod along an upward and downward movement locus of the glass plate and a contact member which has no contact with the supporting rod, by forming trumpet-shaped guide portions at hole edges of the wire fixing portions, and by V-shaping the circumferential surfaces of a tensioner for eliminating slack of the wires.
Abstract:
A cable tension sensing apparatus is mounted on a wall having a door opening. The jack shaft garage door operator includes a drive unit having an electric motor for driving a jack shaft mounted above a door opening. A pull-up cable drum is connected to the jack shaft and has a multi-strand steel pull-up cable that may be payed out to lower a door or wound up to raise the door. The cable tension sensing apparatus includes a cable guide to retain the cable a substantially fixed distance from the wall and a spring driven cable follower which urges against the cable extending between the drum periphery and the cable guide. An alerting switch is connected to the cable follower and sends a signal indicating loss of cable tension when the cable follower moves beyond a predetermined distance. Additionally, the movement of the cable follower moves a door blocking arrangement to a position to block movement of the door when being raised without use of the motor.
