Telescopic plate
A telescopic plate includes a sliding rail structure (10), a rotation structure (20), a drive structure (30) including a motor (31), a circulation structure (40) including an upper connection member (41) and a lower connection member (42), and a support frame (50) mounted on the telescopic sliding rail. The sliding rail structure includes a fixed sliding rail (11) and a telescopic sliding rail (12); the rotation structure including a double-groove wheel (21) mounted at one end of the motor; the upper and lower connection members are wound on the double-groove wheel and extend into the fixed sliding rail to fix with the telescopic sliding rail; a positioning bolt (111) is provided on an inner wall at the tail end of the fixed sliding rail; a positioning groove (1211) is provided at the front end of the telescopic sliding rail; the upper and lower connection members pull the telescopic sliding rail to implement sliding of the support frame in the fixed sliding rail; the positioning bolt and the positioning groove are cooperative so that the telescopic sliding rail rotates around the positioning bolt. A motor is used for controlling to slide and rotate the support frame; a rotation angle can be adjusted by means of a remote-control operation so as to meet user requirements.

MULTI-PART TREAD STRIP
A tread strip for a vehicle is formed of at least two parts, an inner part and an outer part. The inner part is configured for attachment to the vehicle and/or to an outer part. The outer part is configured for attachment to the inner part and/or the vehicle. The outer part further includes an intermediate portion extending along a longitudinal axis between two attachment portions, the two attachment portions being configured for attachment to the inner part. The inner part has an intermediate portion extending along the longitudinal axis between two end portions. The end portions are configured for attachment of the inner part to the vehicle and/or for attachment to the outer part. The tread strip may be mounted to a vehicle by attaching the inner part and then attaching the outer part to the inner part and/or sealing the inner part with respect to the vehicle.

RAILROAD FREIGHT CAR ACCESS FITTINGS
A railroad freight car may have external fittings, such as trackside-accessible ladder fittings that permit personnel to climb onto the decks and walkways of the car. Several embodiments of movable ladder assemblies are described that provide an extended or deployed or raised position of a handhold, and a retracted or lowered, or stored position. In other embodiments, the assembly is provided with a compliant member that allows the handhold resiliently to flex when encountered by solid objects such as shipping containers.

VEHICLE DOOR LEAF FRAME AND VEHICLE DOOR LEAF, FOR EXAMPLE FOR A RAIL VEHICLE
A vehicle door leaf frame, in particular a rail vehicle door leaf frame, preferably for an inwardly opening vehicle door leaf for an entry door. The vehicle door leaf frame has a plurality of, in particular precisely four, hollow frame profiles constituting the actual vehicle door leaf frame. The hollow frame profiles are produced from a plurality of, in particular precisely two, different hollow profiles. In an alternative embodiment, a vehicle door leaf, in particular a rail vehicle door leaf, preferably an inwardly opening vehicle door leaf for an entry door, has a vehicle door leaf frame and is itself pressure-tight and/or water-tight.
