A hold-open lock apparatus of a sliding door configured to limit or release rotation of a swing arm without interference with a rail is provided. The hold-open lock apparatus includes a catch unit including a catch pin that serves as a center of rotation of the swing arm, a catch fitted over the catch pin, and a pawl release lever rotatably fitted over the catch pin. The hold-open lock apparatus further includes a pawl unit including a pawl pin located on a side of the swing arm, and a pawl rotatably fitted over the pawl pin and configured to be locked to or unlocked from the catch. The hold-open lock apparatus also includes a cable unit connected to the pawl release lever and configured to rotate the pawl release lever. The pawl release lever is configured to rotate in one direction to rotate the pawl.

An outer pinch sensor is an integral assembly for mounting on a double sliding door arrangement that covers an opening. The integral assembly includes a bracket, and a seal and sensor mounted to the bracket. The bracket is mounted to a leading edge of one of the doors, the leading edge leading the door when the door is moved in a closing direction. The bracket includes a flange for mounting to the door. When mounted to the door, the seal is arranged inboard of the sensor for sealing to an outer surface of the other door. The sensor is arranged furthest in the closing direction than the other components of the assembly so as to sense the presence of an object in the opening. A signal generated by the sensor may then be used to perform emergency operations for the door to prevent pinching of the object.

The present invention concerns a housing (1) for the transportation of a cargo, such as truck trailers, housings mounted on the chassis of a truck, or shipping containers. The housing of the present invention comprises: (a) walls (1R) defining a closed inner space (1i), (b) an opening (2) provided in one of the walls, and further comprises a rigid door comprising one or more rigid panels (3) which are movable to seal or unseal said opening (2); (c) a flexible fast door comprising a motorized driving mechanism (10) suitable for moving a leading edge (4L) of a flexible shutter (4), wherein the flexible shutter (4) comprises two lateral edges engaged in parallel guiding rails (7) fixed to two parallel and opposite edges of the opening (2), wherein the rigid panel (3) and/or the parallel edge of the opening (2) is provided with a groove to accommodate the guiding rails (7).

A latch structure includes: a door that is changeable between a closed state in which the door covers a door opening provided on a peripheral wall of a vehicle and an opened state in which the door opens the door opening; a floor panel that constitutes a floor surface of an interior space; a door-side engaging portion mounted on the door; and a floor-side engaging portion mounted on the floor panel and engageable with the door-side engaging portion when the door is in the closed state.

A motor control device including a PWM control part is provided. The PWM control part has a two-phase complementary PWM control part, and when driving opening and closing of an opening/closing body, PWM-controls upper switching elements and lower switching elements of three phases in a three-phase inverter circuit based on an energization mode that sequentially switches among energized phases, which are two of the three phases, and a non-energized phase, which is a remaining one phase. The two-phase complementary PWM control part, in one of the energized phases, controls one of the upper switching element and the lower switching element by a PWM signal, and controls the other by a complementary PWM signal having a polarity opposite to the PWM signal, and, in the non-energized phase, controls one of the upper switching element and the lower switching element to be off, and controls the other by the complementary PWM signal.

A method for driving an electromechanical sliding door in a transportation vehicle, wherein the sliding door has an adjusting mechanism with a rolling carriage guided in a guide rail and a first electric drive motor. A fixing mechanism with a second electric drive motor and also a locking mechanism is also provided, which locking mechanism allows the rolling carriage to be arrested in any desired position. Here, the locking mechanism is driven by the second electric drive motor. The method may include driving the second electric drive motor with an input voltage which lies below a threshold voltage for tripping the locking mechanism, continuously increasing the input voltage for the second electric drive motor, and locking the locking mechanism when the input voltage for the second electric drive motor exceeds the threshold voltage for tripping the locking mechanism.

A bifold door includes a first hinge and a second hinge configured to rotatably couple the bifold door to a doorframe. The bifold door includes a slider configured to slide within a track of the doorframe as the bifold door is opened and closed. At least one of the first hinge, the second hinge, and the slider includes a spherical bearing and a pin.
