There is provided an automatic locking device for mounting to a wall-bed having a frame portion anchored to a wall and resting on a floor and having a pivotable mattress support portion adapted to be pivoted to upright storage position and to a deployed horizontal position as a sleeping surface. The automatic locking mechanism being mounted to the bed frame portion anchored to a wall and being automatically actuated by any sudden forward tipping movement of the frame portion should it become dislodged from the wall while the mattress support portion is in its deployed horizontal position. Also provided is a wall bed and kit comprising the automatic locking device of the present invention.

A motorized hinge device (1) has a first connection means (3) assigned to be fixed to a structure or framework of an appliance, and connected, at least by means of a connecting rod means (5), to a second connection means (7) assigned to be fixed to a door of the appliance. This second connection means (7) is hinged to the first connection means (3) by means of a hinge pin means (11). An actuator (13) has a body (15) fixed to the first connection means (3) and a movable member (17) which is movable with respect to the body (15) and is connected to the connecting rod means (5). In an operative condition, the actuator means (13) is operated to move, by means of the connecting rod means (5), the door around the hinge pin means (11) between extreme opening (A) and closing (C) conditions, and vice versa.

A positionable hidden hydraulic hinge configured for installation of a door is provided. The positionable hidden hydraulic hinge includes a non-movable device body configured to be connectable with a door frame, a rotatable device body configured to be connectable with a door leaf, and a hinge configured to connect the non-movable device body and the rotatable device body. The rotatable device body includes a bearing guiding base having a guiding groove and a hydraulic chamber body. The positionable hidden hydraulic hinge also includes a linkage assembly configured to penetrate throughout the hinge. Two ends of the linkage assembly are configured to pivotably connect with the non-movable device body and an internal mechanism of the rotatable device body, respectively. A first end of the bearing guiding base is fixedly connected with the hinge, and a second end of the bearing guiding base is connected with the hydraulic chamber body.

A door hinge has first and second leaf assemblies. The first assembly is formed with a longitudinal guide groove. First and second links are connected to each other for relative pivoting about a vertical axis. The first link is pivoted in a longitudinally displaceable slide in the groove. This slide has a length longitudinally of the guide groove and a width transversely of the guide groove. The ratio of the length to the width of the slide is at least 2:1.

A vehicle door device includes: first and second link arms; a door-side engagement portion that is provided at a close-side end portion of the door that opens and closes a door opening of the vehicle; and a vehicle body-side engagement portion that is provided at a close-side end portion of the door opening that the close-side end portion of the door comes into contact with and separates from, in which one side of the door-side engagement portion and the vehicle body-side engagement portion includes an axial engagement portion extending in a vertical direction of the vehicle, the other side of the door-side engagement portion and the vehicle body-side engagement portion includes a guide groove having a pair of side wall portions, and the axial engagement portion is disposed inside the guide groove at an opening-and-closing operation position in the vicinity of a fully closed position of the door.

An embodiment of the present disclosure provides a swing-in type of door structure of a vehicle that includes a door disposed in parallel at both sides of an entrance of a vehicle, and a door arm mounted on one side of the door to open or close the door by rotation, including: a center door bracket of which one end is fixed to one surface of an upper center of the door and that extends in a direction perpendicular to the door; a roller bracket of which one end is coupled to the other end of the center door bracket in a direction perpendicular to the center door bracket; and a roller mounted on the other end of the roller bracket and coupled to be rolled and rotated while in contact with a rail formed on a vehicle body of an upper side of the door.

A locking mechanism for a door has a lever that is mounted on the door that can be rotated on the door to enable the door to be opened or closed. A first disc, located on the door, is triggered by moving the lever. A shaft is located on the door in contact with the first disc and moves along an extension direction when the first disc is triggered. A slot is located on the body in the direction that the shaft extends, and into which the shaft is inserted in a removable way. The locking mechanism has an open position (I) in which the shaft is located far from the slot and the door can be opened by the user and a lock position (II) that limits the movement of the door, in which the shaft is almost completely contained in the slot.

A hinge device for the rotatable movement of a closing element, such as a door, a window, a shutter or the like, between a closing position and an opening position, includes a fixed element anchorable to a stationary support structure; a movable element anchorable to the closing element so that the movable element rotates around a first longitudinal axis between a first opening position and a second closing position; a plunger that is operatively coupled to the movable element by a coupling system configured so that along a first section of the sliding of a connecting shaft, the plunger does not slide, thereby allowing a free rotation of the movable element, and along a second section of the sliding of the connecting shaft, the plunger slides integrally joined with the connecting shaft, thereby controlling the rotation of the movable element.
