Abstract:
The invention relates to a drive device (20) for entrance/exit devices for public transit vehicles, comprising a drive unit (22) disposed in and driving a column (24) that rotates about an axis of rotation Z-Z during opening and closing operations, said column opening and closing an entrance/exit device. The drive unit (22) is supported in the vehicle by way of a support component (40) and the support component (40) acts as a counterbearing for a torque of the drive unit (22). A coupling device (72) is disposed between the drive unit (22) and the support component (40), said coupling device facilitating a rotation of the drive unit (22) about the axis of rotation Z-Z when a limit of the torque acting on the drive unit is exceeded.
Abstract:
A linear actuator for gates, doors or similar has an actuator arm (1) which is articulated to a support (3) around a vertical axis (15) and be raisable angularly around a horizontal inclination axis (16). The actuator arm (1) has a screw (7) which is operated by an electric motor (11) and a running nutscrew (8) articulated to the gate wing (5) by means of a leadnut holder (18) in which the nutscrew (8) is housed in a manner turning around an axis horizontal and transversal to the actuator arm (1). The leadnut holder (18) has a vertical lower articulation pivot (20) which engages from above in a turning manner in a bush (22) fastened to the wing (5). In an emergency the actuator is disengaged from the gate wing (5) by raising the actuator arm (1) angularly around its inclination axis (16) and extracting upward the articulation pivot (20) of the leadnut holder (18) from the bush (22).
Abstract:
A construction of a door glass guide in a motor vehicle, wherein a door glass (10) of a three-dimensional curved surface is vertically movably guided, characterized in that: slide members (14) each having a spherical head portion (14C) being shifted into a compartment (12) are mounted at least at upper end portions of front and rear end edges (10A and 10B) of the door glass (10); a pair of front and rear guide channel portions (18A and 18B) are provided on a door frame (16), the guide channel portions (18A and 18B) having curvatures substantially equal to respective curvatures of the front and rear end edges (10A and 10B) of the door glass (10) in the longitudinal section thereof, for vertically, slidably guiding the slide members (14).
Abstract:
PURPOSE: A door fixing device is provided to stably maintain the temporarily opened state of a door by enabling a user to simply rotate a stopper. CONSTITUTION: A door fixing device(100) comprises a fixed plate(120), a hinge part(140), and a stopper(160). The fixed plate is coupled to the bottom surface of a door(D). The hinge part is formed on the surface of the fixed plate and has a diagonal hinge hole. One bent end of the stopper is rotatably coupled to the hinge hole, and a packing(162) is coupled to the other end to support the packing to the ground after the door is rotated.
Abstract:
A link device capable of controlling height in refrigerator doors is provided to absorb a load and noises generated due to inaccurate installation of the refrigerator doors through ball joints to realize smooth automatic returning of the doors. A hinge device(20) having automatic returning power are installed at a position separated from a rotary shaft(5) of doors(3). A support bracket(11) is fixed at a main body, wherein the rotary shaft of the door is installed. A driving link(14) has one end combined with a shaft of the hinge device to transmit automatic returning power of the hinge device when the door is closed. A driven link(13) has one end combined with the other end of the driving link rotatably, and the other end combined with the support bracket rotatably to restrict the door to return centering on the rotary shaft in accordance with automatic returning of the driving link. First and second ball joints(16,17) connect both ends of the driven link to the driving link and the support bracket rotatably, and support the rotary shaft movably.

Abstract:
PURPOSE: A sliding door is provided to reduce the production costs of equipment required for using a screw shaft by easily and cost-efficiently producing a screw shaft. CONSTITUTION: A sliding door is composed of a screw shaft(20), a guide rail(30), a guide roller(40), a bracket(60), a slide block(70), a lifting unit(90) for lifting and lowering the slide block. The screw shaft is rotated by a drive motor. The guide rail is installed to be horizontal with the screw shaft. The guide roller is moved along the guide rail. The bracket connects the guide roller to a door(50). The slide block is coupled to the bracket. The lifting unit is coupled to the slide block and enables a user to separate the slide block from the screw shaft.
