An actuating apparatus (1) for opening and closing a cover in or on a vehicle, having a locking and/or arresting kinematics that cooperate with the cover. The actuating apparatus includes a housing (2) and an actuating part (3) received in the housing (2) and movably supported relative to the housing (2). The actuating part (3) cooperates with the cover in such a way that the actuating part (3) performs a movement relative to the housing (2) between a first position and a second position upon a movement of the cover between a closed position and an open position, wherein, in the first position, the actuating part (3) is in a locked state. The actuating apparatus (1) further includes an elastically deformable spring system (4) associated with the actuating part (3), in particular having a progressive spring characteristic.

The present invention provides a system for automatic operation of a top hatch cover for a container, comprising a hatch cover, a cylinder mount, a main operating lever, a connecting link, and a hatch locking lever. The cylinder mount is configured for pivotally connecting a piston to the container. A lower portion of the main operating lever is connected to a cylinder rod of an air cylinder. A first extension of the connecting link is rotatably connected to an upper portion of the main operating lever and a second extension of the connecting link is coupled to the hatch cover. The main operating lever and the hatch locking lever are rotatably coupled to a main shaft mount, where the hatch locking lever is configured to pivot around the main shaft mount to move between a locked position and an unlocked position.

A refrigerator comprising a door rotatable about a hinge shaft. A door opening and closing apparatus comprises a drive motor, a first gear configured to receive power from the drive motor, a second gear, spaced apart from the first gear, configured to transmit a rotational force to the hinge shaft, a clutch gear configured to be rotatable around a rotation axis of the first gear, and configured to transmit power of the first gear to the second gear based on a position of the clutch gear around the rotation axis of the first gear, and a position detection sensor configured to detect the position of the clutch gear so that while the clutch gear is at the position, the clutch gear transmits the power received from the first gear to the second gear which transmits the rotational force to the hinge shaft to open and close the door.

An automatic disengaging linkage system including a housing operably connectable to a garage door trolley and a garage door arm. The housing can define a main bore configured to receive a portion of the garage door arm. A ball can be receivable in a ball bore defined in the housing. A biasing member can be configured to force the ball in engagement with the garage door arm or an arm pin associated with the garage door arm. The ball or the biasing member can be configured to disengage with the garage door arm with the housing when a predetermined pulling force is applied to the housing. The garage door arm can automatically be disengaged with the housing upon encounter a sufficient pulling force that retracts the ball into its ball bore thereby allowing the garage door arm to move freely out from the main bore.

A vehicle tailgate with an integrated collapsible door comprises a tailgate having an outer wall, an inner wall and a cavity there between, a door section of the tailgate having an inboard wall and an outboard wall and being moveable between a closed position and an open position substantially within the envelope of the tailgate, the inboard wall and the outboard wall being connected by a linkage to permit relative movement there between, a first track to guide the motion of the inboard wall and a second track to guide the motion of the outboard wall, and a power drive unit to power the motion of the door section, such that in the closed position of the door section the inboard wall is flush with the inner wall of the tailgate and the outboard wall is flush with the outer wall of the tailgate, and in the open position of the door section at least a portion of the inboard wall and at least a portion of the outboard wall lie within the cavity between the outer wall and the inner wall of the tailgate.

A track door system for an aircraft includes a door having a first side and a second side opposite the first side. A first roller track and a second roller track are aligned adjacent one another on the first side of the door. A third roller track and a fourth roller track are aligned adjacent one another on the second side of the door. A first motion driver is configured to move the door along the first roller track and the second roller track. A second motion driver is configured to move the door along the third roller track and the fourth roller track. A drive unit is operatively coupled to the first motion driver and the second motion driver to provide electromechanical power for cooperatively moving the door forward to an open position or aft to a closed position.

A sealing assembly for pressing a garage door horizontally into weather stripping or a door jamb; the sealing assembly having at least one cam-stop assembly, the cam-stop assembly further having at least one cam assembly, at least one linking assembly coupling the cam-stop assembly to the cam assembly, and at least one stop brace. The garage door is sealed when a combination of cam-stop assemblies having cam assemblies—further comprising at least two triangular hinge plates and corners—couple with stop braces and rotate counter-clockwise by exertion of torque to move the garage door forward and downward to form a snug seal with the side of the door jamb and also the bottom floor.

A nut leadscrew type automatic door opening and closing mechanism for moving a door of a motor vehicle relative to a vehicle body. The nut leadscrew type automatic door opening and closing mechanism includes a driving device, a leadscrew, a nut pushing block and a pushing rod. The driving device is fixedly connected to a door, the leadscrew is rotatably mounted on the door, the nut pushing block is sleeved on the leadscrew, a first end of the pushing rod is hinged to the nut pushing block, and a second end of the pushing rod is hinged to the vehicle body. The driving device is capable of driving the leadscrew to rotate, so as to allow the nut pushing block and the pushing rod to be reciprocally linearly movable along the leadscrew to allow the pushing rod to drive the door to open or close relative to the vehicle body.

A powered actuator includes a leadscrew as an extensible member connected to a closure, such as a vehicle side door, and is configured to move linearly for opening or closing the closure. The first powered actuator also includes a gearbox having a gearbox housing, the gearbox configured to apply a force to the extensible member for causing the extensible member to move linearly. One or more sealing assembly seals the gearbox housing as the extensible member translates linearly. A gearbox housing may include apertures on opposite sides thereof, with one aperture facing a shut face and the other aperture facing an inner cavity of the closure. The extensible member may be sealed at each aperture relative to the gearbox housing. One sealing assembly may be fixed at an aperture, with the extensible member translating therethrough.

A device for assisting the opening and closing of a door in a structure. The device may comprise: a door shaft configured to rotate about a longitudinal axis thereof in both a first direction and in a second opposite direction, and configured to be mounted to the structure to form a hinge about which the door may rotate in the both the first and second directions relative to the structure; a first actuator linked to the door shaft and configured to control a speed of rotation of the door shaft in the first direction; and a second actuator linked to the door shaft and configured to drive rotation of the door shaft in the second direction. The second actuator is an electromechanical actuator.
