A power door system for actuating door panels between closed and opened positions. An operator arm telescopically supports a push rod. A housing is secured to the operator arm. A spring pin extends through apertures in the arm and the push rod. A release cable extends from the housing and is movable to retract the pin, permitting inter-telescoping motion of the push rod relative the operator arm, in turn permitting manual displacement of the doors. A compression spring supported within the housing influences the pin into engagement with the operator arm and push rod. A locking pin and guide is incorporated into a cable mounting guard below the spring pin, the locking pin displacing with the spring pin to a retracted position in response to actuation of the release cable, a successive actuation of the release cable releasing the spring pin and lock pin to reengage the apertures in the arm and the push rod.

A door system includes a panel to translate along a normal path between an open position and a closed position in front of a doorway in a wall. The door system further includes a first track to support the panel from an upper portion of the panel, and a second track to extend along the normal path proximate a lower portion of the panel. The door system also includes a spring to urge the panel toward the second track to maintain the panel in the normal path.

A guide system includes a guide rail for guiding a door wing, a running carriage to be connected to the door wing and displaceably supported along the guide rail, and a carrier on which the running carriage can be arranged. The carrier is movably supported in a direction transverse to the longitudinal direction of the guide rail. The carrier can be moved into a transfer position in which the carrier adjoins the guide rail in the longitudinal direction. A locking device can releasably lock the carrier in the transfer position to restrain a movement in the transverse direction. The locking device includes a movably-supported locking element for releasably locking between the guide rail and the carrier, and a control contour curved so that the running carriage can be moved over a region in the transverse direction. The movably-supported locking element includes a supporting element displaceable along the control contour.

A guide system for guiding a door wing, in particular a folding-sliding-door, movably supported relative to a furniture carcass. The guide system includes a guide rail having a longitudinal direction, the longitudinal direction of the guide rail extending substantially parallel to a depth direction of the furniture carcass in a mounted condition on the furniture carcass. A carrier is provided for movably supporting the door wing, and the carrier is displaceably supported at least over a region along the guide rail. An abutment is provided for determining an end position of the carrier in the longitudinal direction of the guide rail, and an adjustment device can adjust a position of the abutment. The abutment can be adjusted by the adjustment device in the longitudinal direction relative to the guide rail.

A guide system for guiding a furniture door, in particular a folding door or folding-sliding door, relative to a fixed furniture part includes a first guide rail and a running carriage which can be connected to the furniture door and which has a rolling body via which the running carriage is movably mounted on the first guide rail. The first guide rail has a running surface for the rolling body of the running carriage, and the first guide rail is assembled in the longitudinal direction from a first rail piece and one second rail piece. The two rail pieces can be releasably connected via a connecting piece on which there is formed a portion of the running surface for the rolling body of the running carriage.

A furniture hinge includes a first fitting portion and a second fitting portion, the second fitting portion being pivotally connected to the first fitting portion by a hinge axis member. At least one of the fitting portions includes a base plate to be fixed to a furniture part, and an adjusting plate coupled to the hinge axis member, the adjusting plate being displaceably arranged on the base plate. A preferably pivotally mounted adjustment element can adjust a position of the adjusting plate relative to the base plate along a linear guide to adjust a position of the first fitting portion relative to the second fitting portion. A gap is formed between the first fitting portion and the second fitting portion in at least one relative position of the furniture hinge, and the adjustment element can be actuated by introducing a tool into the gap.

A device for moving folding door leaves that open completely and are adapted for wardrobes or pieces of furniture in general include a single door leaf or one pair of door leaves hinged to each other, configured to be rotated from a completely closed configuration to a completely open configuration. The door leaves include a guiding device, the action of which is damped during the opening and closing movement by magnetic devices and damping systems that counteract their attraction force.

A guide system includes a first guide rail and a second guide rail for guiding furniture parts. The second guide rail extends transversely relative to the first guide rail in a mounted position. A guiding device is to be connected to one of the furniture parts, and is movable relative to the first and second guide rails and can be transferred in a crossing region between the first and second guide rail. The guide system has a drive device with an entrainment member acted upon by a force storage member and configured to be releasably coupled to the guiding device. The entrainment member is locked in a parking position and can be unlocked by an entry of the guiding device into the crossing region. Thus, the entrainment member and the guiding device coupled therewith can be retracted along the second guide rail by a force of the force storage member.

A bifold door includes an upper panel including a top edge disposed proximate an anchor and a lower edge disposed distal of the anchor. The upper hinge, connecting the anchor to the top edge, permits rotation of the top edge of the upper panel but prevents elevation of the top edge of the upper panel. A first actuator, connected to the anchor and the upper panel, lifts the lower edge of the upper panel upwardly and outwardly, and effects lifting of the upper panel. A lower panel, separated from the upper panel, includes an upper edge disposed proximate the lower edge and a bottom edge disposed distal of the lower edge. A second actuator, connected to the upper panel and to the lower panel, lifts the upper edge of the lower panel upwardly and outwardly, and to effect lifting of the lower panel.

A package receiving and returning device for fitting to a sloping roof/building. The device has a storage cavity with an opening, a frame bounding the opening and a displaceable cover arranged in the frame which displaces from a closed first position wherein the opening is sealed thereby preventing access to the storage cavity, to an open second position which permits access to the storage cavity. A sensor detects presence of an unmanned aerial vehicle (UAV). A verification system verifies a designated UAV for a requested delivery or collection. An automated mechanism displaces the cover between the first and second positions when activated upon detection of the verified UAV to allow a payload to be delivered into, or retrieved from, the storage cavity. The automated mechanism positions the cover to define an entrance that corresponds to the features of the UAV and/or a payload to be received/returned, and/or environmental conditions.
