Abstract:
A door closer, comprising a door closer housing mounted to one of a door frame or a door surface and a linkage arm for pivoting the door between open and closed positions. The linkage arm has a first and second end, the first end mounted to the other of the door frame or the door surface. The door closer includes a rotatable connector between the linkage arm and the door closer housing, the linkage arm second end engaging with the rotatable connector. The connector has a rotatable body portion and head protrusion substantially secured in a female receptor to transmit rotation about a longitudinal axis of the connector. One or both of the head protrusion or female receptor has a curved profile and is further movable with respect to the head protrusion to permit limited rotational misalignment of the linkage arm on any axis perpendicular to the connector longitudinal axis.
Abstract:
The invention relates to a spindle drive for an adjusting element of a motor vehicle comprising a drive motor with a spindle-spindle nut gear arranged downstream for producing a drive force along a geometric spindle axis, wherein two connectors are provided for transferring the drive force and wherein at least one connector comprises a ball joint with a ball socket and an assigned ball, wherein the ball socket comprises a ball socket housing with a connecting piece. It is proposed that the ball socket in the ball socket housing has a damping shell and a bearing shell in the damping shell for the positive engagement with the ball so that the flux of force for the drive force passes via the damping shell and the bearing shell.
Abstract:
The invention relates to a drive device (20) for entrance and exit devices for public transportation vehicles, comprising a drive unit (22) that is arranged in and drives a rotary column (24) rotating about a rotational axis Z-Z during opening and closing operations, said column opening and closing the entrance and exit device. The drive unit (22) is held on the vehicle via a retaining component (40). The retaining component (40) acts as counter bearing for a torque of the drive unit (22). Between the drive unit (22) and the retaining component (40), a coupling device (72) is arranged, which enables a rotation of the drive unit (22) about the rotational axis Z-Z when a threshold value of the torque acting upon the drive unit is exceeded. Between the coupling device (72) and the retaining component (40), a bearing is provided, which enables a tumbling motion of the rotary column (24) with the coupling device (72) and prevents a rotation about the rotational axis Z-Z.
Abstract:
The present invention relates to a rail and a door roller of a window and door system and a window operation apparatus for windows and doors using the same. The rail and the door roller of a window and door system and the window operation apparatus for windows and doors using the same according to the present invention include: one or more upper linear rail units 1 which are installed on an upper end of a window casing, are opened downward so as to rectilinearly guide a door roller 3 that is installed on an upper end of a window frame and has a vertical shaft 3a or a diagonal shaft 3b, have guides 4 that are vertically or diagonally formed at both sides thereof, and are rectilinearly formed to have a predetermined length; and one or more upper meandering rail units 2 which diagonally or curvedly guide an upper door roller 3, which rectilinearly moves on the upper linear rail unit 1, so as to operate the window frame in a horizontal direction, are installed to be connected to one side end of the upper linear rail unit 1 so as to be connected to the guides 4 of the upper linear rail unit 1 with the same cross section, and have guides 4 that are diagonally or curvedly extended.

Abstract:
A motorized door opener for a vehicle (such as a military or security vehicle), featuring a sensor system that determines door position to prevent door damage while the opener is in operation. The opener features an offset gear system that effectively changes the door's rotation point. Mechanical advantage is gained by using a lengthened lever arm with the gear system, providing increased leverage and allowing the motor to provide enough force to open and close a heavily armored door. The opener can use existing door hinges, and can be provided so as not to protrude into the door space, in order to facilitate passenger and equipment entry/exit through the doors. A safety release mechanism is included in some embodiments, allowing the door to be manually opened or closed.
Abstract:
A suspension wheel apparatus for glass doors includes a suspension wheel set, a wheel seat and a bridging element. The bridging element is screwed on a clamping fixture to hold a glass door and has an arched round head held by the wheel seat to form an arched surface contact. Thus the bridging element can be directed to an upright position without skewing forwards, rearwards, leftwards or rightwards. The wheel seat has a conical orifice to increase the swinging room of the bridging element. Therefore, the glass door can be moved smoothly and steadily for opening or closing in close contact with a track, and adjustment can be made accurately and securely.
Abstract:
A drive device for moving a flap of a vehicle includes a first fastening element which can be connected to one of a moveable component and a fixed component, and a housing tube which is axially movable relative to the first fastening element. The housing tube has an end opposite the first fastening element which carries a second fastening element which can be connected to the other of the moveable component and the fixed component. A spindle drive includes a threaded spindle having end mounted for rotation in the housing tube and fixed against axial movement with respect to the housing tube, and a spindle nut arranged on the threaded spindle. The spindle nut is connected to the first fastening element and secured against rotation with respect to the housing tube, and a rotary drive is arranged to drive the spindle in rotation.
Abstract:
A power actuator system for a movable vehicle panel such as a lift gate assembly includes a position sensor that detects the pivotal movement of a strut mechanism of the power lift gate assembly relative to the host vehicle. A rotary sensor is coupled directly to an end component of the strut mechanism and provides signals that indicate the total amount of pivotal or rotary movement of the strut mechanism and the lift gate during the opening and closing of the lift gate. The signals provide information to determine the absolute position of the strut and the lift gate for processing in the vehicle's electronic control unit.
Abstract:
A drive device for a moveable part, in particular a hinged side window of a vehicle, with an actuating drive and with a threaded piece which is driven by the actuating drive and which meshes with an associated threaded piece, the associated threaded piece moving the part, there being provision, in order to reduce undesirable noises, for individual flights of at least one threaded piece (14) to be designed in such a way that they come to bear under the effective force in the respectively associated flights of the other threaded piece.
