An automatized mechanical opening/closing device is mounted to an oven mouth of an oven device and includes an outer door frame assembly, an inner door frame assembly, a door panel, a first driving device, and a plurality of second driving devices. The first driving device and the second driving devices are set in electric connection with a control platform is, so that the first driving device is operable to drive the inner door frame assembly to move inside the outer door frame assembly in an X-axis direction and the second driving devices is operable to drive the door panel to move inside the inner door frame assembly in a Y-axis direction. The control platform can be used to set automatized opening and closing operations of the oven mouth of the oven device to thereby save human labor and to reduce material damage due to manual operation.

A lock device for locking the sliding door comprises a first lock portion and a transmission portion. The transmission portion may move along relative to the first lock portion a predetermined path, so that the transmission portion may bring the sliding door to move along the predetermined path to open or close the sliding door. The transmission portion has a plurality of successively arranged mating portions for locking with the first lock portion. The first lock portion has a first position in which the first lock portion is locked with the transmission portion and a second position in which the first lock portion is released from the transmission portion. The transmission portion may be locked in different positions along the predetermined path by matching the first lock portion 110 with different mating portions, so that the sliding door can be locked in different positions.

A fastening arrangement for fastening a vehicle sliding door to a vehicle body while enabling opening and closing of the sliding door. The fastening arrangement includes a motion element configured for being movingly arranged within or on a vehicle body guiding rail for enabling movement of the motion element along the vehicle body guiding rail, and a variable-length motion mechanism connected to the motion element and configured for being fastened to the sliding door at a lower attachment area of the sliding door. The variable-length motion mechanism is configured for enabling variable distance between the motion element and the lower attachment area of the sliding door.

An apparatus is provided for moving and securing articles in a pickup truck cargo bed. The pickup truck cargo bed may have opposing sidewalls, cab wall, tailgate, and floor. The apparatus comprises a plurality of tracks configured to connect to the pickup truck cargo bed, the plurality of tracks extending substantially along a longitudinal length of the pickup truck cab and defining a channel. A push plate slidably is mounted to the plurality of tracks with a movement member, and the push plate configured to stand perpendicular to the floor. The apparatus also comprises an actuator in mechanical communication with the push plate, the actuator configured to move the push plate to a desired position in the pickup truck cargo bed. An adjustable enclosed area is defined by the push plate, opposing side walls, and tail gate.
