The guide system includes a carrier for movably supporting the at least one door wing, a guide rail configured to be fixed to the stationary furniture part for guiding the at least one carrier, a guiding device for displaceably supporting the at least one carrier along the guide rail, a running carriage configured to be coupled to the at least one door wing, and a receiving device for receiving the at least one running carriage. The receiving device adjoins the carrier in a longitudinal direction of the carrier, and the receiving device is movably supported relative the carrier in the longitudinal direction of the carrier.

A furniture drive for moving a furniture part movably supported relative to a furniture carcass the furniture drive includes a housing having a first housing wall to be fixed to the furniture carcass, and a second housing wall at least partially spaced from the first housing wall. At least the first housing wall includes a guide device for guiding a fastener. At least one supporting body is configured so as to be separate from the guide device for guiding the fastener, at least partially surrounds the guide device, and is firmly connected to the first housing wall as well as to the second housing wall so that a movement of the second housing wall relative to the first housing wall is restrained.

An arrangement for guiding a sliding door or folding-sliding door on a furniture wall includes a first guide system to be fastened on the furniture wall and a second guide system to be fastened on the furniture wall at a vertical distance from the first guide system. The two guide systems each have at least one guide and a guide body which is displaceably mounted on the guide, and a carrier on which the sliding door or folding-sliding door is to be fastened and which is connected in a movement-coupled manner to the two guide bodies of the guide systems. The carrier is assembled in the vertical direction from at least two carrier portions, and the at least two carrier portions can be releasably connected.

A vehicle barrier gate system which is positioned above a roadway through which vehicles pass. Some of the various embodiments of the present disclosure include a gate comprised of an arm and barrier which is adjustable between a raised position in which a vehicle may pass and a lowered position in which a vehicle is prevented from passing. The gate may be movably connected to a ceiling or an overhead support structure positioned above the roadway. Various types of actuators may be utilized to adjust the gate along a linear and/or angular path between the raised and lowered positions. A control unit may be in communication with one or more sensors and/or an authorization system to control the actuator. The gate may include a breakaway mechanism which allows the gate to be manually raised or lowered in the event of actuator failure or a vehicle ramming through the gate.

In a position adjustment mechanism of a hinge device, operability of an adjustment screw is assured, and rickety movement is prevented while enhancing load bearing property. An adjustment screw 40 of a hinge device 3 is screwed to a body member 10. A locked part 34 of the intervention member 30 is sandwiched between a pair of sandwiching faces 44a of the adjustment screw 40 each other. To both lateral faces of the locked part 34, a contact part 35e having a ridge shape and a clearance part 35b continuous to a lateral side of a contact part 35e for avoiding contact with a sandwiching face 44a are each formed.

A window lift assembly for adjusting a window pane, including a carrier, a flexible traction means for transferring an adjusting force for adjusting the window pane and a deflecting piece, which is non-rotatably arranged on the carrier and has a guide channel for deflecting the traction means in a guide plane. To retain the traction means in the guide channel, at least one securing element on the carrier and at least one securing section are provided, the at least one securing element and the at least one securing section may be formed so that if sections of the traction means are displaced out of the guide channel toward the securing element and the traction means thus contacts the securing element, the securing section continues to block the traction means against a displacement transverse to the guide plane out of the guide channel.

A furniture drive for moving a furniture part movably supported relative to a furniture carcass the furniture drive includes a housing having a first housing wall to be fixed to the furniture carcass, and a second housing wall which is at least partially spaced from the first housing wall. At least the first housing wall includes at least one guide device for guiding a fastening means. At least one supporting body is configured so as to be separate from the at least one guide device for guiding the fastening means, at least partially surrounds the at least one guide device, and is firmly connected to the first housing wall as well as to the second housing wall so that a movement of the second housing wall relative to the first housing wall is restrained.

An arrangement for guiding a sliding door or folding-sliding door on a furniture wall, comprising a first guide system to be fastened on the furniture wall and a second guide system to be fastened on the furniture wall at a vertical distance from the first guide system. The two guide systems each have at least one guide and a guide body which is displaceably mounted on the guide, anda carrier on which the sliding door or folding-sliding door is to be fastened and which is connected in a movement-coupled manner to the two guide bodies of the guide systems. The carrier is assembled in the vertical direction from at least two carrier portions, and the at least two carrier portions can be releasably connected.

The present invention relates to a device capable of guiding a stable rotational actuation between a first support bracket fixedly connected to a supporting frame side of a door frame and a second support bracket fixedly connected to the door side in a gear hinge unit constituting a rotating door, specifically, in a door hinge in which a gear hinge unit is provided between the first support bracket fixedly connected to the support frame side of the door frame and the second support bracket fixedly connected to the door side, by minimizing the compressive stress generated in the lower gear hinge unit under a neutral axis of the door and the tensile stress generated in the upper gear hinge unit above the neutral axis of the door by the rotational moment applied to the gear hinge unit due to the load of the door, it is possible not only to secure and maintain the correct opening/closing performance of the door, but also to minimize damage to parts caused by friction or friction noise in the door hinge.
