The invention relates to a door drive system for a wing of a door, a window or similar, comprising a housing with a drive and/or return device, e.g. a closing spring (7), and a preferably hydraulic damping device. In practice, drive housings of this type are cast in aluminium. The production costs are relatively high since housing openings and boreholes such as hydraulic channels have to be cut into the housing (31) later on. According to the invention, the housing (31) is produced wholly or partly from plastic. This enables the cavities which are necessary for the housing to function, such as housing boreholes and/or openings to be made in the drive housing when it is produced, without removing material by cutting. According to another design, the drive housing has several housing parts which are produced separately. The adjacent sections of the housing parts are then stuck or welded together. Housing boreholes such as hydraulic channels can be made in the adjacent surfaces of the housing parts which are shaped accordingly, without removing material by cutting.

A power operating apparatus for a vehicle door moveable between an opened position and a closed position, includes a drive mechanism provided at the inside of a vehicle body with respect to a door opening of the vehicle door to power move the vehicle door in an opening direction toward the opened position and in a closing direction toward the closed position, and a power-transmission mechanism mechanically linking the drive mechanism with the vehicle door to enable power transmission between the drive mechanism and the vehicle door. A through-opening in the body panel of the vehicle body so that the through-opening is arranged outside of the inner peripheral edge of the door opening. The power-transmission mechanism having at least a linkage portion capable of going into and out of the interior of the vehicle body. The linkage portion of the power-transmission mechanism is inserted into the through-opening, so that the locus of power movement of the linkage portion is generated outside of the inner peripheral edge of the door opening.

An automatic sliding door opening and closing system comprises a continuous, powered belted drive system and a clamp arrangement capable of fixably and releasably attaching the automotive sliding door to the belt drive system so as to be automatically driven along a predetermined path and capable of releasing the belt drive system under predetermined conditions. The powered belt drive system is located so as to be combined with one of the door's standard sliding door hinge systems. The clamp arrangement is a rotary device biased into a pinching engagement on the belt of the belt drive system via a cam and spring arrangement.

A powered panel control apparatus and method is used with an electric motor having a rotatable armature. The control detects and generates time periods between the rotation of the armature over a predetermined constant amount of angular rotation. An average time period is computed over a predetermined number of time periods and compared with a threshold time period to determine if an obstacle is present in the path of movement of the panel. Transient counts are accumulated for increasing average time periods over a number of time period samples to detect an obstacle. Endzone ramp compensation adjusts a threshold for the initial entry of the panel into a seal.

A bi-fold door is equipped with door lifting devices operated with an electric motor drive to selectively open and close the door. The door lifting devices have winches operable to wind and unwind elongated webs connected at one end to rotatable members of the winches and anchored at the opposite end to the door. Anchors mounted on the door have adjustable sleeves operable to adjust the working lengths of the webs.

A method of programming a controller for a movable barrier operator includes enabling and disabling an input device within a predetermined period of time, a predetermined number of times. This sequence of short activations of an input device, such as a switch on a wall unit, puts the controller in a learn mode or a programmed state. Thereafter, the controller is responsive to learn any of the various routines that can be programmed for the movable barrier operator, such as transmitter code, limits of travel, force settings, and so on.

A door controlling device for opening and closing a door in a wall having a linkage connecting between the door and a wall and an arm pivotable about a pin. A drive member on the pin has a stand by position which does not interfere with the manual movement of the door. Rotation of the drive member in one direction rotates the arm around the pin to move the door to the open position and rotation of the drive member in the opposite direction rotates the arm around the pin to move the door to the closed position.

A tailgate folding device for an automotive vehicle constructed to vertically fold a midsection of the tailgate and thereby to avoid an external lower end thereof from touching a ceiling when the tailgate is opened at a place where the ceiling is low, thus promoting an effective use of the tailgate even at a confined area. The device has a tailgate vertically foldable and dividable via a hinge point into an upper portion and a lower portion thereof, a manipulating unit mounted at a folded site of the tailgate to control folding of the tailgate, and a locking unit for adequately converting a relative rotation of the divided tailgate from a restricted state to a released state according to the operation of the manipulating unit.

A movable barrier or garage door operator has a barrier drive for moving the movable barrier or garage door between open and closed positions. Motion of the barrier is detected by a tachometer connected to the barrier drive or by upper and lower barrier travel limit switches. A test is made to determine if the barrier has been commanded to be in a closed state and to determine if a preselected time interval has elapsed following closure of the barrier. When both of those conditions are present and the door is moved upward without authorization an alarm signal is generated and can signal the barrier drive to apply a closing force. The timer prevents the barrier from being closed on a person or obstacle during normal operation and prevents injury. An obstacle detector also prevents unwanted closure on an obstacle.

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.
