摘要:
A latch assembly connected to the drive unit of a bi-fold door for retaining the bi-fold door secure to a building has elongated straps attached to rotatable latch drums mounted on the outer ends of the drive shaft of the drive unit. Lift drums powered by a motor driven gearbox raise and lower the bi-fold door. Latch assemblies having springs attached to the straps maintain tension on the straps during the opening and closing of the bi-fold door.

An operable wall assembly having a prime mover for deploying and stowing or stacking the wall panels. The operable wall assembly includes a control system for controlling operation of the prime mover and sensors for determining when the panels are fully deployed and fully stacked. The wall panel is installed by applying a three-point camber for spans in the range of 33-40 feet.

A motor control system comprises a motor control circuit, a non-transitory storage medium and a processing circuitry. The storage medium is configured to store a current threshold profile that is indicative of a current requirement of the motor control circuit for an operational cycle of a motor. The processing circuitry is configured to adjust the stored current threshold profile based on a change to the operational cycle of the motor (e.g., from standard to non-standard).

A balance system used with a door of a cupboard comprises a transmission shaft, a first pulley on the transmission shaft, and a balance component. The first pulley is connected to a door belt, one end of the door belt is secured to the first pulley, and the other end of the belt is connected to the door. The balance component comprises a balancing member, a balancing belt and a second pulley on the transmission shaft. One end of the balancing belt is connected to the second pulley, and the other end of the balancing belt is connected to the balancing member, such that the balancing member is hung on the second pulley. The first pulley and the second pulley rotate synchronously, and the door belt and the balancing belt are wound oppositely. With the balance system, a small driving force can open/close the door.

An articulated door system includes one or more door sections; a lifting block associated with a lower door section of the one or more door sections; a frame supporting the one or more door sections and engaging the lifting block; and a lead screw system including a rotatable lead screw that is configured to engage the lifting block and lift the lower door section up and down based on rotation of the lead screw.
摘要:
A powered folding door or window system includes at least two rigid panels that are linked together by at least one vertical hinge/pivot to fold between a closed state, where the panels extend across an opening, to an open state, where they are retracted to one side of the opening and stacked against each other. The system incorporates a motor and a drive belt mechanism as primary means for driving the panels. The system further includes a powered actuator on one of the panels and a co-operative element on a linked adjoining panel; whereby the powered actuator cooperates with the co-operative element on the linked adjoining panel to move the linked adjoining panel and said one panel about the vertical hinge/pivot linking them; whereby the powered actuator may start the opening of the door or window system and/or complete the closing of the system.
摘要:
The method serves for operating a system with a foldable element that is provided with a control unit including at least two foldable elements, that are connected each via connecting shafts to related carriages, which are slidably supported in a running rail and of which at least the carriage connected to the front-sided foldable element is provided with a drive motor, the method including the step of executing a learning drive, with which the system with foldable elements is transferred from at least a first into a second position and related information is captured. According to the invention at least at the front-sided carriage data of the acting load and related position data are captured and therefrom status data of the installed system with foldable elements are determined and provided to an operating program, that controls the at least one drive motor depending on to the determined status data.
摘要:
An automatically operated door system for an aircraft toilet is provided. The system has a folding door and a door frame. The folding door is arranged in the door frame to be movable between a closed door position and an open door position. The system also has a drive apparatus for moving the folding door between the closed door position and the open door position, a guiding member connected to the drive apparatus and a displacement element arranged on the folding door. The guiding member engages the displacement element to transfer the driving force of the drive apparatus to the displacement element; accordingly, the folding door is moved from the closed door position into a pre-folded door position.
摘要:
A new door system and related technology for a passenger carrying rail vehicle, such as a President's Conference Committee (PCC) streetcar rail vehicle, and a method for retrofitting a rail vehicle door system with the new door system. In some embodiments, the new door system includes an electro-mechanical angle drive motor, a solid door control pivot rod, a door leaf panel clamp that is permanently connected to the solid door control pivot rod, a lever arm that includes a positive locking device and that is coupled to the solid door control pivot rod, and a connecting rod that is attached to the electro-mechanical angle drive motor and to the lever arm to enable the connecting rod to impart motion generated by the electro-mechanical angle drive motor to the lever arm.
