An automatic hatch assembly for bulk material containers includes a hatch cover which covers a fill opening of the container, and may be retrofitted to existing containers equipped with a conventional hatch cover. A drive unit is operable to open and close the hatch cover, and a locking assembly actuates an extendable lock member. Optionally, a pneumatic seal is provided within the cover for sealing the container from the outside environment. The locking assembly is adapted to resist opening forces applied to the cover, such as when the container is pressurized, and a sequencing controller may be provided to facilitate automated operation of the opening/closing, locking/unlocking, and/or sealing/unsealing of the hatch cover.

A retractable outside door handle assembly may include a handle unit including a pushing portion and an outside door handle mounted selectively protruded outwardly to a handle housing, an actuator including a drive motor, a worm connected to the drive motor, a worm wheel engaging with the worm, and an operation rod that moves according to rotation of the worm wheel to push the pushing portion, and a door latch lever that is rotatably mounted on the handle housing and rotates during operation of the outside door handle protruded by operation of the actuator.

A motor vehicle door latch which is equipped with a locking bolt and a locking mechanism interacting with the locking bolt, including a catch and a pawl. The motor vehicle door latch possesses a stop lever pivotably located on the control lever, which interacts with a protrusion on the catch beyond a main ratchet position and a pre-ratchet position, whereby the protrusion corresponds to a third ratchet position with an increased distance of the locking bolt in respect of the main ratchet and pre-ratchet position compared to a catch axis. The stop lever impinges a triggering lever lifting the pawl from the catch in order to open the locking mechanism.

A cover opening-closing device comprises a rod, a casing in which at least a portion of the rod is stored, a lock unit, an interlock mechanism, and a connection unit. The lock unit can rotate about a central axis line between a lock position, in which locking with the cover is possible, and a release position, in which locking is not possible. The interlock mechanism is configured so that the rotation of the lock unit and the displacement of the rod are interlocked. The connection unit is configured so as to connect the lock unit to the casing and to restrict displacement of the lock unit in the direction of the central axis line.

A door latch assembly, includes: a catch support assembly, the catch support assembly including a strike body having a pin receiving aperture therein; a catch arm assembly rotatably mounted to the catch support assembly; a latch pin positioned in the pin receiving aperture and movable between a retracted position and an extended position, the latch pin protruding above the strike body in the extended position to impede rotational movement of the catch arm assembly; and a first roller mounted to the catch arm assembly and configured to engage a first side of the latch pin in the extended position; and a second roller mounted to the catch support assembly and configured to engage a second side of the latch pin in the extended position. The latch pin includes a material having a hardness of 60 Rockwell C or more, the first roller includes a material having a hardness of 33 Rockwell C or less, and the second roller includes a material having a hardness of 60 Rockwell C or more.

A concealed handle assembly that includes a handle base and a handle body rotatable about a first axle such that one end of the handle body can extend or return to a concealed state, the first axle being disposed on the handle base, the handle body having a handle body initial position, a handle body first open position, and a handle body second open position. The assembly further includes a rocker arm rotatable about a second axle, the second axle being disposed on the handle base, the rocker arm having a rocker arm initial position, a rocker arm first open position, and a rocker arm second open position, the rocker arm being capable of being rotated away from or returned to the rocker arm initial position as the handle body rotates, the rocker arm being capable of driving a bolt.

A door handle assembly may have an adjustable door handle having a handle support structure. The assembly may also have an adjusting mechanism for adjusting the door handle between a starting or non-use position and a use position. The adjusting mechanism may have at least one drive unit and a force transfer element which is operatively connected to the handle support structure of the door handle to shift the door handle from the starting or non-use position into the use position or vice versa and which is designed as a roller mechanism.
