An enhanced hinge and method pivotally and removably connects a member from a structure. In one example, the hinge and method retains the member using a first hinge piece coupled to the structure and a second hinge piece coupled to the member. The first and second hinge pieces may be configured such that the second hinge piece is retained inside the first hinge piece in a closed position and is not free to be decoupled from the first hinge piece but is free to pivot to an open position at the closed position. At the open position the second hinge piece is inverted as compared to its position in the closed position, is free to pass through the first hinge piece and is free to be decoupled from the first hinge piece.

The present disclosure relates to a pulley device, a sliding door, and a sliding window. The pulley device includes: a pulley component including a pulley; a connecting component including a rocker, one end of the rocker being rotatably connected to the pulley component; and a housing including a bottom plate and two side plates. The two side plates are fixed to two opposed sides of the bottom plate, respectively, so that the bottom plate and the side plates jointly define a receiving cavity configured to receive the pulley component and the connecting component. A surface of the side plate facing the receiving cavity defines a receiving groove along a length direction of the side plate, and the other end of the rocker is received in the receiving groove and is capable of sliding along the receiving groove.

A method and device for reducing excessive door or hatch closing velocity. An actuator containing a force alignment channel causes piston movement within a hydraulic cylinder creating resistance to prevent door or hatch slamming. Closing of the car door is against the resistance of the hydraulic cylinder as hydraulic fluid moves through at least one channel to allow hydraulic fluid to move from a first side of the piston to a second side of a piston. The resistance of the hydraulic cylinder to an incremental movement in the car door varies during the closing of the car door. A force alignment channel within an actuator creates variation of the resistance of the hydraulic cylinder to the incremental movement in the car door by varying a rate of movement of the piston within the hydraulic cylinder per degree of closure of the car door.

A slim-profile safe has a safe body that defines an interior space, and a safe door that is moveable between a closed position for securing the interior space and an open position for accessing the interior space. The safe door includes a fore portion and a recess portion that is offset from the fore portion by a recess angle. The fore portion defines a maximum depth of the safe, and the recess portion provides a reduced depth portion of the safe for the presentation of external hardware for operating a lock that releasably locks the safe door in the closed position, the recess portion being sufficiently offset from the fore portion such that the external hardware is positioned entirely sub-flush to a plane that extends parallel to the fore portion.

The present invention includes a height raising member body mountable to an upper end of a frame disposed above an entrance of a car that moves up and down through an elevator shaft, in which a rail for guiding a car door in an opening and closing direction and a pulley for use in opening and closing drive of the car door are mounted to the frame. The height raising member body characteristically includes: a base part connectable to the frame; and a supporting part capable of supporting the motor at a position upward away from the base, the motor being configured to drive the pulley via a belt.

A port-door release assembly includes a door and a linkage coupled to the door to support the door during movement between open and closed positions. The port-door release assembly includes a drive shaft coupled to the linkage to drive movement of the linkage. The port-door release assembly includes a motor configured to rotate the drive shaft which moves the linkage and the door to the open and/or closed positions. The port-door release assembly includes a back-up release assembly movable relative to the linkage to disconnect the drive shaft from the linkage which allows the door to move to the open position without actuation of the motor. A door assembly includes the port-door release assembly as described above and a housing defining a port in which the door is movable relative to the housing between the open position that uncovers the port and the closed position that covers the port.

A door operator including an output shaft, a ball screw, a powered driver, and a yoke. The output shaft is configured to be coupled to a door. The powered driver is operatively coupled to the ball screw and configured to rotate the ball screw in a first rotational direction. The yoke is coupled to the ball screw and configured to translate in response to rotation of the ball screw. The yoke is configured to rotate the output shaft.

Proposed is a door hinge. More particularly, there is provided a door hinge which is conveniently assembled, has a minimized shape, and above all, enables a closing force to be applied to a door so that when the door is opened, high-temperature heat is inhibited from being released from inside an apparatus on which the door hinge is installed.

An engine hood drive for an engine hood system of a motor vehicle includes a drive unit for delivering a torque at a predetermined adjusting angle between a passive position and an active position. A drive lever is connected in a torque-transmitting manner to the drive unit for pivoting between the passive position and the active position and which has an actuating end. A driving slot has a guide receiver for the actuating end of the drive lever. The driving slot is pivotable about a flap hinge for an engine hood at a predetermined flap angle between a closed position and an open position. The driving slot is transferrable in the direction of the open position as a result of a pivoting movement of the drive lever from the direction of the passive position in the direction of the active position.

The pulley device includes: a pulley component including a pulley; a connecting component including a rocker, one end of the rocker being rotatably connected to the pulley component; and a housing including a bottom plate and two side plates. The two side plates are fixed to two opposed sides of the bottom plate, respectively, so that the bottom plate and the side plates jointly define a receiving cavity configured to receive the pulley component and the connecting component. A surface of the side plate facing the receiving cavity defines a receiving groove along a length direction of the side plate, and the other end of the rocker is received in the receiving groove and is capable of sliding along the receiving groove.
