The shaft has a drum from which a draw cable (42) extends to be unwound against the spring force of the coil spring. The free end of the draw member is fixed relative to the closed door panel in the upper area thereof on the fixed frame or building.
Abstract:
The invention concerns a self-contained motor-operated assembly for driving a sliding gate, characterised in that it comprises a power-operated unit (100) and a support (200) wherein the unit (100) is mounted with clearance and can slide in a generally vertical direction, the motor-operated unit (100) including at least a wheel (7) driven by the motor (4) and a battery (5) for powering the motor (4), the wheel being capable of being urged in contact with the ground (18) under the effect of the very weight of the motor-operated unit (100).
Abstract:
A door operator for moving a door includes a motor for moving the door between opened and closed positions, an operator for controlling the operation of the motor, and a switch, such as a wired wall station or a remote transmitter, for enabling the operator to control operation of the motor. Pushing and releasing the switch results in the operator allowing the motor to apply a normal range of torque values, and wherein pushing and holding the switch results in the operator allowing the motor to apply a broader-than-normal range of torque values. An external safety device coupled to the operator may be used with the operator. If the external safety device is enabled and the door is closing, the motor allows application of a higher-than-normal range of torque values. The door operator may also take corrective action if excessive door speed is detected. But, this corrective action can be overridden if the switch is held closed for a predetermined time.
Abstract:
Die Erfindung betrifft ein Tor mit einem aus mehreren zueinander verschwenkbaren Gliedern bestehenden Torblatt, das in einem gebäudefesten Rahmen seitlich geführt aus einer vertikalten Schließstellung in eine zumindest annähernd horizontale Offenstellung bewegbar ist, wobei das Tor eine Gewichtsausgleichseinheit aufweist, die aus mindestens einer durch Drehung vorspannbaren, auf einer horizontalen Welle angeordneten Schraubenfeder gebildet ist, wobei die Welle mit der Schraubenfeder unmittelbar am Torblatt angeordnet ist. Erfindungsgemäß wird die Welle am im verschlossenen Zustand des Tores oberen Bereich des Torblattes angeordnet.

CONSTITUTION: An opening and closing device(32) for a ventilation window for an agricultural product storage comprises a motor, first and second fixtures, a connector(300), and a cover(400). The motor supplies driving force for opening and closing a ventilation window. The first and second fixtures connect the drive shaft(36a) of the motor and the rotary shaft(22) of the ventilation window to each other. The connector connects the other end of the first fixture and one end of the second fixture to each other and transfers driving force from the motor to the rotary shaft of the ventilation window. The cover covers the other end of the first fixture, one end of the second fixture, and the connector.
