The present disclosure provides a method of opening a boarding door of a vehicle that provides use of a trunk room to a passenger reserving the trunk room. The method comprises keeping the boarding door closed until both a first condition and a second condition are satisfied and opening the boarding door or enabling the boarding door to be opened in response to both the first condition and the second condition being satisfied. Here, the first condition is that the passenger is in the vicinity of the boarding door. The second condition is that the trunk door is closed or that a reservation of the trunk room is cancelled.

The present invention provides a refrigerator, comprising a refrigerator body and a door body. A hinge body is disposed on the refrigerator body. A first hinge shaft and a second hinge shaft are disposed on the hinge body. A first guide groove and a second guide groove are formed in the door body. The first hinge shaft is located in the first guide groove and the second hinge shaft is located in the second guide groove. During opening of the door body, the first guide groove moves relative to the first hinge shaft and the second guide groove moves relative to the second hinge shaft, the first hinge shaft applies an acting force to the first guide groove to drive the end, away from the first guide groove, of the second guide groove to approach the second hinge shaft, so that the door body is displaced in a horizontal direction.

The invention relates to a door arrangement (1) for a first enclosed space enabling a sealed connection between the first enclosed space and a second enclosed space, comprising a flange (2) defining an opening into the first enclosed space, a door (4) hingedly mounted on the flange (2), means for securing the flange of the second space pressed against the flange of the first space, the means comprising locking catches (8) which are movable between an unlocked position in which they are recessed inside the flange (2) and a locked position in which they project radially from the flange (2) to the opening, thereby locking the flange of the second space without rotating the flange (2) by engaging each catch in a notch provided on the outer peripheral edge of the flange of the second space.

In a door hinge device for the vehicle, in a vehicle without a B pillar, a hinge slider connected to a hinge portion of a door slides and moves in an external diagonal direction of a vehicle body along upper and lower rails by a driving torque of a motor inside a case, securing a rotation trajectory of the door, and then a striker fixed to the hinge slider is restrained by a latch portion fixed to the case to fix the slide movement position of the hinge slider, ensuring stability of the opening/closing operation of the door.

A door hinge apparatus of a vehicle may include a rail plate provided on one side of a vehicle body corresponding to an end portion of a door of the vehicle and formed with a rail in a width direction of the vehicle, a hinge slide unit including a slide bracket provided on the rail and a door hinge bracket provided on the door where the slide bracket includes a guide slot formed in a diagonal direction of the slide bracket and the slide bracket and the door hinge bracket are pivotally coupled each other through a hinge shaft, and an actuator having a roller configured at a rod to roll along the guide slot so that the slide bracket moves along the rail.

The present invention provides a refrigerator, comprising a cabinet, a door and a hinge body, wherein a positioning shaft and a guiding shaft are provided on the hinge body, and a positioning groove and a guiding groove are provided on the door; the door of the refrigerator according to the present invention may be moved by a distance in a direction away from a pivoting side when being opened, thereby avoiding inconvenience of opening the door due to the protrusion of the side wall of the door.

A door hinge apparatus of a vehicle may include a main bracket provided on one side of a vehicle body corresponding to an end portion of a door of the vehicle and having slide slots formed on upper and lower plates, respectively, a slide hinge bracket engaged to the slide slots to be slidable along the slide slots of the main bracket by a link mechanism, and a door hinge bracket Provided on the end portion of the door and pivotally connected to an external end portion of the slide hinge bracket through a hinge shaft.

A step device for a vehicle includes a movable step and a coupling member. The movable step includes a guide rail. The coupling member is configured to cause the movable step to move from a deployed position to a retracted position as a engaging part comes into sliding contact with a side wall of the guide rail that is located on an inner side in a vehicle width direction and, while pressing the side wall, moves inside the guide rail in a direction of closing a sliding door. The guide rail is configured such that a terminal end region on a closing side including a terminal end position at which the engaging part is located when the sliding door is fully closed constitutes a closing-side free running zone in which the engaging part does not press either of the side walls.

An example retention assembly has a motor assembly and a self-locking worm drive coupled thereto. A cam is fixed to a worm gear of the worm drive. The retention assembly has an actuation shaft including a follower. The actuation shaft is displaceable over a displacement range via rotation of the cam. The retention assembly has a securement member with a securement member follower, the securement member coupled to a portion of the actuator shaft. The retention assembly has a housing cam included as part of the retention assembly housing and against which the securement member follower is biased. The securement member are in an open state when the actuation shaft is in a first position. The securement member swings outward to a retaining position as the actuation shaft is moved to a second position.

The invention relates to a door arrangement (1) for a door with a first enclosed volume, the arrangement permitting a sealed connection between the first enclosed volume and a second enclosed volume, and comprising a flange (2) defining passage opening and a passage axis (O) perpendicular to the opening plane, a door (4) pivotably mounted on the flange (2) and a chute for discharging (10) components which is movable between a discharge position in which the chute is positioned opposite the passage opening and a position in which the chute is spaced apart from the passage opening, the chute being attached to the flange (2) by means of a first double-jointed link mechanism (11) comprising a first link (12) arranged to permit a rotational movement about an axis (C) parallel to the passage axis (O) of the passage opening and a second link (13) arranged to permit a rotational movement about an axis (D) perpendicular to the passage axis (O) of the passage opening.
