Provided are a cab for a work machine and a work machine capable of preventing a door from opening against an operator's intention. The cab includes a cab body, a door, and a gas spring. The cab body is formed with a doorway. The door is rotatably supported on the cab body. The door opens and closes the doorway. The gas spring biases the door in the closing direction.

An embodiment is a vehicle door opening and closing apparatus including a vehicle door configured to be selectively opened and closed in a mode of a sliding mode and a swing mode to uncover and cover a door opening of a vehicle body. The vehicle door opening and closing apparatus further including a rail mounted on the vehicle body, a roller unit including a roller and a hinge element, the roller being configured to be guided along the rail, the hinge element being spaced apart from the roller, a door-side bracket mounted on the vehicle door, the door-side bracket being detachably connected to the roller unit, and a body-side bracket mounted on the vehicle body, the body-side bracket being detachably connected to the roller unit.

A door opener with an anti-loose linking unit includes a driving device and a linking unit disposed between the driving device and the door. The driving device includes a motor and a first transmission member operatively connected to the motor. The linking unit includes a first push rod connected via a connecting screw to the first transmission member, permitting joint pivotal movement. An anti-loose member is non-rotatably mounted on the first push rod. Ahead of the connecting screw is non-rotatably coupled with the anti-loose member. Thus, the connecting screw cannot rotate relative to the first transmission member and the first push rod, reliably preventing the first push rod from disengaging from the first transmission member.

An entrance system (1) comprising a swing door member (10) having a door leaf (12), and an automatic door operator (30) is provided. The automatic door operator (30) has a motor (34) capable of causing movement of the door member (10), a controller (31) for controlling operation of the motor (34), and the automatic door operator (30) being operable in a testing mode (60) and an operational mode, wherein the controller (31) is configured, in the testing mode (60), to automatically determine at least one test parameter; and causing an action in response to the determined test parameter.

A decelerated hinge for supporting, so as to oscillate, a door of an item of furniture, which comprises a first hinge part which can be affixed to a fixed part of the item of furniture, a second hinge part which can be affixed to a door of the item of furniture and connected to the first hinge part by way of an articulation system which comprises a plurality of connecting levers and at least five articulation axes, and a deceleration device which comprises an actuating member that is moveably arranged in a first connecting lever of the articulation system, and at least one actuation surface for the actuating member of the deceleration device is provided inside a second connecting lever which is adjacent to the first connecting lever of the articulation system.

Methods and systems are provided for an automated door system for a vehicle. In one example, the automated door system may include a key fob configured with a transmitter. A set of sensors may be located at a door of the vehicle which may be communicatively linked to a vehicle control unit. A position of the key fob relative to the door may be monitored by the set of sensors to provide hands-free actuation of the door motor.

Methods and systems are provided for an automated door system for a vehicle. In one example, the method for a vehicle may include operating an automated door system to enable hands-free actuation of a set of door vehicles while the height of the vehicle is not changing and when the vehicle height is changing, suspending operation of the automated door system until the floor has stopped changing height.

An automated window mechanism is disclosed, including a motor secured to a window, the window being in a frame and wherein the motor causes the window to move relative to the frame in two directions: an open direction being defined as a direction toward which movement of the window relative to the frame causes the window to be more closed, and a closed direction defined as a direction opposite the open direction. The mechanism also includes a transmission component that transfers power from the motor to movement of the window relative to the frame, the transmission component having a backup defined as a distance the transmission component can move from a first point at which further movement in the open direction will cause the window to begin moving in the open direction, and a second point at which further movement in the closed direction will cause the window to begin moving in the closed direction. The mechanism also includes a processor and memory storing one or more computer-readable instructions executable by the processor to perform acts. The acts include instructing the motor to move the window relative to the frame, and upon the window reaching a desired position relative to the frame, reversing the transmission component into a neutral range within the backup to release energy stored in the transmission component.

A railcar system that includes a railcar with a discharge opening and a longitudinal gate positioned adjacent to the discharge opening. The system further includes a driving system connected to the longitudinal gate that is configured to move the longitudinal gate between a closed position and an open position. The system further includes a controller connected to the driving system that causes the driving system to position the longitudinal gate in the closed position, position the longitudinal gate in the open position, and position the longitudinal gate to remain an at least partially open position. The longitudinal gate is less than fully open when the longitudinal gate is in the at least partially open position.

A vehicle door opening and closing device includes: a detection unit having three or more detection sections configured to detect an object, wherein each of the detection sections has a detection range for the object, and two or more operation zones are defined by partial overlapping of the detection ranges of the detection sections which are adjacent to each other; and a control section configured to cause a door driving section to control a door to open and close when a predetermined movement performed by the object is detected in any of the two or more operation zones. The control section is configured to use detection results of two of the detection sections corresponding to the operation zone where the object has first been detected for detection of movement of the object in preference to other detection results.
