A system and method for controlling motion of a door are provided. The door is moveable between an open position and a closed position and has a balanced position whereat the door does not move towards the open position nor the closed position under an effect of gravity. The system includes a power actuator for moving the door to a partially open position between the open position and the closed position. The power actuator is adapted to allow the door to move to the balanced position after the power actuator has moved the door to the partially open position.

A hybrid drive-thru door system that includes a door panel assembly movable between a plurality of operating modes. The door panel assembly includes a sliding door panel operable for movement between a closed position to at least partially cover a doorway opening and an opened position to at least partially expose the doorway opening. The sliding door panel has an upper sliding door panel member releasably attached to a lower sliding door panel member. The upper sliding door panel member is independently movable relative to the lower sliding door panel member in a window operating mode of the door panel assembly.

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.

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.

The invention discloses a synchronous sliding mechanism, a side hidden door system, and a cabinet body with the side hidden door system. The synchronous sliding mechanism comprises a guide rail and a first connecting rod mechanism, wherein the first connecting rod mechanism comprises two sliding ends provided on the guide rail; and when the guide rail reciprocates in a horizontal axial direction, the two sliding ends are close to or far away from each other. Through connection between connecting rods and the guide rail, the guide rail may reciprocate stably and synchronously. The synchronous sliding mechanism is widely suitable for furniture such as door bodies, cabinet bodies and the like, and has an excellent effect.

An arrangement for guiding a door on a furniture wall, includes a guide to be secured on the furniture wall, a carrier on which the door is to be secured, and a guide body. The carrier is/can be connected to the guide body such that they are coupled for movement, and via which the carrier is/can be moveably mounted on the guide. A securing device is provided comprising a mounting body that is/can be connected to the carrier and/or to the guide body, a second mounting body that is/can be connected to the guide and/or to the furniture wall, and a securing element. The securing element fixes the two mounting bodies in a secure position relative to one another and releases the same in a release position, such that the two mounting bodies can be moved relative to one another.

A door connection structure includes a door guide for guiding a door in the longitudinal direction of a vehicle body, a door hinge arm mounted on the vehicle body, and including a hinge rotation shaft and a door rotation shaft, the door hinge arm rotating around the hinge rotation shaft when the door is sliding, a door hinge rotatably mounted around the door rotation shaft and connected to the door, a first catcher rotatably mounted on the door hinge arm and of which a center striker guide is formed thereto, and a center striker which is inserted into the center striker guide to rotate the first catcher and limits rotation of the first catcher when the door swings so that the door swings around the door rotation shaft.

A vehicle includes a body having a door frame defining a door aperture, a vehicle door, a rail mounted on the body, a roller unit mounted on the vehicle door and configured to move along the rail and allow the vehicle door to open and close in a sliding mode and a swing mode, a center rail extending from an edge of the door aperture, a center roller unit including rollers configured to be guided along the center rail, a roller bracket having the rollers mounted thereon, a roller-side hinge element connected to the roller bracket, and a door-side hinge element rotatably connected to the roller-side hinge element by a hinge pin, a door-side docking unit releasably connecting the door-side hinge element to the vehicle door, and a frame-side docking unit releasably connecting the roller-side hinge element to the door frame.

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

A door hinge device for a vehicle is disclosed. In the door hinge device for the vehicle according to an embodiment of the present disclosure, in the vehicle without the B pillar, as the hinge slider connected to the hinge part of the door slides and moves in the outer diagonal direction of the vehicle body along the rails inside the case to secure the rotation trajectory of the door, and then the slide latch part configured in the hinge slider restrains the striker fixed to the case by the linked operation of the link arm connected to the door hinge bracket, thereby the slide movement position of the hinge slider is fixed, and then the opening/closing operation of the door is stably achieved.
