  • Patent number: 10449976
    Abstract: A plug door opening-closing apparatus includes a lock mechanism, a drive mechanism, and a door support mechanism. The lock mechanism is directly or indirectly arranged on one of the upper and lower portions of at least one door of a vehicle. The lock mechanism locks the door when completely closed so that the door does not open. The drive mechanism is coupled to the lock mechanism and drives the lock mechanism to switch the door from an unlocked state to a locked state. The door support mechanism is mechanically coupled to the lock mechanism and supports the door. When the completely closed door is switched from the unlocked state to the locked state, the door support mechanism is adapted to hold the door and hinder outward displacement, in a vehicle width direction, of the other portion of the door where the lock mechanism is not arranged.

    Abstract: A side sliding door apparatus for a vehicle includes one of two sliding doors driven by an actuator, and the other moves in conjunction with the one sliding door via a direction converting mechanism. When the sliding door is in a closed condition, a latch rod is inserted into a lock hole to lock the sliding doors in the closed condition. A roller is pushed up on a cam surface when the sliding doors are opened, which releases the locking. An upper level surface of the cam surface forms an inclined surface with a downward gradient, which prevents the roller from unexpectedly going beyond the starting end of the upper level surface and dropping due to vibration or the like being applied to the slider in the unlocked condition, and prevents the locking with the locking mechanism in response to the next sliding door closing command.

  • Patent number: 8136299
    Abstract: The present invention provides a sliding door opening/closing device for a vehicle that applies a sufficient opening/closing drive force to the left and right sliding doors and reduces a force necessary to lock and unlock the latch, despite a simple configuration of the device, and that facilitates the manufacturing process, improves operability and safety, and reduces noise. A lock device, against both sides of which locking portions abut, rotates a columnar permanent magnet so as to form magnetic locking circuits and fixes the locking portions by magnetic forces of the locking magnetic circuits. The rotational operation of the columnar permanent magnet is converted into the downward operation of a latch, and the lowered latch restrains the locking portions with respect to the lock device.

    Abstract: An automated coupling mechanism for sliding doors that are movably mounted upon a storage unit. The coupling mechanism may comprise a rotating mechanism comprising a rotating member, and connecting unit. The storage unit may comprise at least one outer sliding door and at least one inner sliding door comprising an upper track, where the connecting unit connect the rotating mechanism to the outer sliding door. The rotating member and the track may be made from material of substantially high friction coefficient to enable the rotating member to move the inner sliding door along the track when rotated. The connecting unit, which are connect the rotating mechanism to the outer sliding door, may enable the outer sliding door to move in the opposite direction of the inner sliding door, whereby the inner sliding door is moved by the rotating mechanism as a physical counteraction.

  • Publication number: 20100126073
    Abstract: A double door actuation system is provided. The actuation system includes a base frame, a drive motor, first and second guide rails and a pair of rail support arrangements. The drive motor is mounted to the base frame and includes a pinion gear rotatable about an axis of rotation. The guide rails include opposed raceways and a gear rack. The gear rack engages the pinion gear opposite sides such that the pinion gear simultaneously drives the guide rails in opposite directions parallel to a drive axis. The rail support arrangements are mounted to the base frame and support guide rails. The rail support arrangements maintain a substantially constant lateral location of the guide rails in a direction perpendicular to both the drive axis and axis of rotation to maintain a substantially constant mesh between the pinion the gear racks.

  • Patent number: 7578097
    Abstract: A door for a cold storage locker or other applications includes an inflatable or fluid-filled seal system. The seal system comprises a network of pliable tubular seals that expand as air or another fluid is forced air through the seals. Expansion of the seals provides a more positive seal. To inhibit frost from accumulating near the seals, the seals are kept relatively warm by continuously circulating fluid through the seals regardless of whether the door is open or closed. In some cases, the fluid within the seals is heated.

  • Publication number: 20080250716
    Abstract: Systems and methods are described for controlling a breakaway feature in a sliding door. The sliding door can be mounted in a doorway on a door hanger. The door is typically attached at one end using a hinge mechanism and maintained in planar alignment with the doorframe by a controllable mechanism such as an electromagnetic shear lock. An activation switch, such as a push-bar switch, initiates a delayed egress sequence that disengages the shear lock by controlling an energizing current in a magnet. When the shear lock is disengaged, the door can swing on the hinged mechanism. The delayed egress sequence can include one or more delays prior to disengaging the shear lock. Override signals can inhibit or force disengagement of the shear lock.

  • Patent number: 7254918
    Abstract: An emergency unlocking device for locking and unlocking systems for swinging sliding doors, in particular of rail vehicles. The emergency unlocking device has a traction device that engages on a first spring-loaded pivoted lever that is connected via a second lever to a third lever. The third lever is attached to the axial shaft of a spring-loaded rotary magnet and has elongate holes in which a bolt is displaceably mounted. When the traction device is subjected to tensile stress, the bolt engages with a fourth lever that is pivotably mounted on a shaft, and moves the fourth lever. The fourth lever is operatively connected via a coupling rod and deflection unit to a locking rod that moves the vertical direction. A rod, via which a force component that brings about the locking and unlocking of the door leaves can be applied, engages on the fourth lever.
