A sliding door structure in which a position where a door side end-section of a vehicle body rail support member is coupled to a door main body being further to a door closing direction side than a center-of-gravity position of a door, and a position of a door side end-section of a door rail support member in a fully open state being further to a door closing direction side than the center-of-gravity position of the door and further to a door opening direction side than a position where the door side end-section of the vehicle body rail support member is coupled to the door main body, and that further includes: an inclination suppressing wall provided at a vehicle body and configured so as to be abutted, from a vehicle lower side, by a reaction force generating section at least in the fully open state.

A sliding door system for a building wall includes first and second wall parts having opposite first and second door openings respectively and separated by an intermediate space, first and second door leaves closing the first and second door openings respectively, a door leaf carrier slidable along the intermediate space by a linear guide device and on which the door leaves are pivotably mounted by a pivot mechanism, and a coupling device converting the carrier sliding movement into a rotational movement actuating the pivot mechanism so that the door leaves pivot relative to the door leaf carrier, the coupling device including a slotted component with a slot representing a desired relationship between the sliding movement and the rotational movement and a control lever coupling the slot to the pivot mechanism, and wherein the slotted component is mounted on at least one of the first and second wall parts.

A method for operating a cargo door of an aircraft includes opening the cargo door inwardly in relation to an opening by pivoting the cargo door to an open position adjacent a ceiling of a cargo space. The cargo door is supported by a door frame during opening of the cargo door. The method further includes moving the cargo door in relation to the door frame to a position wherein the opening is substantially free from the cargo door. The cargo door is supported by a support frame, moveable in relation to the door frame, during this movement.

A showcase includes a fixed case, an openable sliding door, closable on the fixed case, a compression sealing gasket, between the fixed case and the openable door, an upper guide and a lower guide mounted on the fixed case. The openable door is slidably mounted on the upper and lower guides, and both the upper guide and the lower guide are movable between respective extracted positions and respective retracted positions with respect to the fixed case. The showcase also includes lower actuation means, and upper actuation means. The upper actuation means are operatively connected to the lower actuation means and/or to the lower guide.

A sliding door system includes a support guidance for suspending a door leaf with respect to a framework. A steering track is fixed to the framework and an engaging front lever is mounted at a front edge of the door leaf. The support guidance is arranged independent from a steer guidance which provides a design freedom in which a rigidity of the support guidance can be increased independent from the steer guidance. The steer guidance can be designed with a compact configuration. A mechanical chain of connections of the door leaf to the swing shaft can be made more robust by adapting at least one of a slide bar, a sliding carriage and a swing arm, such that a substantial support of the door leaf is provided by this mechanical chain of connections.

The guiding device serves for holding and guiding a sliding door, with which a furniture opening of a piece of furniture can be closed. The guiding device comprises a guide fitting that is connectable to the sliding door and that is connected via a first articulated joint to a first end piece of a guide lever, whose second end piece is connected via a second articulated joint to a guide carriage, which comprises a carriage body that holds at least one guide roller, which is guided in a guide channel that extends at least on one side in a terminal channel section along a curve into the furniture opening.

A sliding door structure in which a position where a door side end-section of a vehicle body rail support member is coupled to a door main body being further to a door closing direction side than a center-of-gravity position of a door, and a position of a door side end-section of a door rail support member in a fully open state being further to a door closing direction side than the center-of-gravity position of the door and further to a door opening direction side than a position where the door side end-section of the vehicle body rail support member is coupled to the door main body, and that further includes: an inclination suppressing wall provided at a vehicle body and configured so as to be abutted, from a vehicle lower side, by a reaction force generating section at least in the fully open state.

An elevator installation includes an elevator cage, which is movable in an elevator shaft, with a cage door suspension for a cage door, wherein the cage door suspension is movably arranged at the elevator cage by means of at least one movable mount. During operation of the elevator installation, a self-centering aligning movement of the cage door suspension from a skewed setting of the elevator cage, in correspondence with a skew setting axis, to an approximately vertical and centered setting of the cage door suspension in correspondence with a vertical, can be performed.

The invention relates to a covering device for a tool deposition station. The covering device includes a covering as well as a mechanism for moving the covering. The mechanism for moving the covering includes a rail and a first driver which is guided by the rail. The first driver is displaceable along the rail and is connected to the covering. The covering device can be brought into an opened position by way of a displacing of the first driver along the rail in a first direction and the covering device can be brought into a covered position by way of a displacing the first driver along the rail in a second direction which is opposite to the first direction. The mechanism is configured such that the displacing of the first driver effects at least a partial translatory movement of the covering.

A hatch operating mechanism is arranged to control opening and closing movements of a hatch covering an opening in a vehicle. The mechanism comprises a first arm and a second arm each having a first end and a second end, wherein each arm is rotatably attached to the vehicle at the first end and rotatably attached to the hatch at the second end. First and second connecting elements extend between and are displaceable relative to a pair of spaced apart, parallel guides fixed to the hatch, wherein the second ends of the arms are rotatably attached to the respective connecting elements. The first arm rotates in a first direction over a first arcuate path, and the second arm simultaneously rotates in an opposing second direction over a second arcuate path; and the first and second connecting elements are configured for reciprocating movement along the guides during rotation of the arms.
