A motor for driving a garage door is controlled by a control unit, which counts the time required for the garage door to move between an upper limit switch and a lower limit switch. The control unit sets a comparison reference time on the basis of the time thus counted, and controls the motor in such a manner that the motor driving does not continue for a period of time longer than the comparison reference time.

A motor for operating the door is controlled for forward and reverse rotations and stoppage by a control circuit responsive to an operation command signal, an upper-lower limit signal, an obstruction detection signal and a maximum drive time over signal, thus controlling the door stepwise for opening, stoppage, closing, stoppage and opening in that order. Upon generation of an obstruction detection signal or a maximum drive time over signal during the closing operation, the control circuit controls the motor in a manner to open the door for a certain period of time, and subsequently upon application of an operation command signal, the control circuit is set in a manner to open the door again.

A garage door operation control apparatus comprises a disc rotatable in interlocked relation with a door driving system, which disc actuates an upper limit switch and a lower limit switch at the door upper and lower limit positions respectively. The interlocked relation of the driving system and the disc may be cancelled thereby to adjust the responsive position of the limit switches.
摘要:
An automatic door operation control apparatus is disclosed which comprises a door operating device a driving device for opening and closing the door, a condition detector for detecting a condition under which the movement of the door by the driving device is required to be discontinued, and a main control device for issuing a driving command to the driving device to actuate the same as required in response to a condition detection signal from the condition detector. The apparatus further comprises an auxiliary control device for stopping the operation of the driving device in the event that the main control device fails to issue a command to the driving device to stop the door movement within a predetermined length of time in response to the condition detection signal from the condition detector.
摘要:
A garage door operation control apparatus includes a door operating system for opening and closing the main door of a garage, a main detection circuit for detecting the open or closed condition of the main door, an auxiliary detection circuit for detecting an open condition of a window or an auxiliary door of the garage, a fire in the garage or generation of a special gas therein, an alarm and a signal processing circuit. Electrical signals from the detection circuit are logically analyzed thereby to control the door operating system and the alarm.

A door member such as a garage door is driven by a motor through a roller chain having a finite length to travel in the garage opening and closing directions. The roller chain is driven by a single drive sprocket driven by the motor to make its reciprocating movement along the same path while making rolling engagement at its roller portion with a guide rail constructed to support the roller portion of the roller chain from the opposite sides. A trolley connected to the door member by an arm is releasably coupled to the roller chain and is also guided along the guide rail while making sliding engagement therewith. A mechanism for detecting abutment of the door member with an obstruction present on the traveling path is provided to detect the above situation when a physical force is imparted to the roller chain due to the abutment. The opening and closing movement of the door member, stopping of rotation of the motor and detection of the presence of an obstruction are electrically controlled.
摘要:
A door operation control apparatus comprising a memory circuit for storing a programmed data on door control processes in the form of a combination of command codes is disclosed. A door operation input signal, a mode or condition detection signal from a door operating device and the condition of the program being executed are used to determine logically the optimum door operating mode, thus controlling the door operating device.
