A door drive mechanism includes a main drive and an auxiliary drive.

In this connection it is provided that the drive assembly of the auxiliary drive is formed as a drive assembly with a linear output and that the drive assembly of the auxiliary drive is borne in a pivot bearing and that the rod system is formed as a slide arm and the rod system bearing is formed as a slide rail.

A door drive mechanism includes a main drive and an auxiliary drive.

In this connection it is provided that the components of the main drive and of the auxiliary drive to be mounted on the door leaf side are borne in or on a common and/or continuous housing mechanism and/or bearing framework mechanism and/or mounting plate mechanism to be mounted on the door leaf side and/or are covered by a common and/or continuous cover to be mounted on the door leaf side.

A door closer assembly for an entryway device having a position sensor that assists in determining the location of the door closer assembly, and thus the location of the associated entryway device, relative to at least an entryway. The position sensor can be coupled to, and/or part of, the door closer assembly. Information obtained by the position sensor may be used by one or processing devices of an access control system to determine whether the door closer assembly and/or the entryway device is at the closed location, among other locations, as well as the direction(s) of displacement of the entryway device. Such information may be utilized in calibrating other devices, as well as determining the occurrence of a number of events, including unauthorized displacement or holding of the entryway device. A timer may also be utilized to further evaluate the nature of the displacement of the entryway device.

A swing door operator system is described, the system including a first swing door operator, a second swing door operator, and at least one door leaf hinged connected at an opening in the wall. The first swing door operator is connected to a first side of the door leaf, the second swing door operator is connected to a second side of the door leaf, the first side of the door leaf is opposite to the second side of the door leaf, and the first swing door operator and the second swing door operator interact to move the door leaf between an open and closed position.

A swing door operator for moving a door leaf between an open and a closed position is described, the swing door operator including at least one drive unit that has a motor and a spring, the motor and spring being arranged to interact to enable moving the swing door leaf between the open and closed positions. The swing door operator also has a control unit that is operatively connected to the drive unit and thereby to the motor and that controls different modes of door operation.

An opening and closing body control apparatus for a vehicle includes an assist control portion configured to detect an operation of an opening and closing body of the vehicle by an operator or a user and control voltage applied to a motor serving as a drive source which applies a drive force to the opening and closing body during the operation of the opening and closing body by the operator or the user. The assist control portion applies an assist voltage and an offset voltage alternately to the motor to operate an assist control for applying the drive force to the opening and closing body. The assist voltage for rotating the motor at a rotation speed which corresponds to an operation speed of the opening and closing body and the offset voltage being lower than the assist voltage.

The live well lid system may comprise a lid, a hinge, a motor, a lift arm, a lid track, and a local foot control. The live well lid system may be a system for covering and uncovering a live well of a boat by pivoting the lid of the live well responsive to input from the local foot control. The live well lid system may be adapted for a user to pivot the lid by operating the local foot control located proximate to the live well without diverting the attention of the user or requiring use of the user's hands. In some embodiments, a remote foot control may be a secondary control located at a remote location on the boat.

A door hinge apparatus of a vehicle may include a main bracket provided on one side of a vehicle body corresponding to an end portion of a door of the vehicle and having slide slots formed on upper and lower plates, respectively, a slide hinge bracket engaged to the slide slots to be slidable along the slide slots of the main bracket by a link mechanism, and a door hinge bracket Provided on the end portion of the door and pivotally connected to an external end portion of the slide hinge bracket through a hinge shaft.

A door actuator linkage includes a lever extending along a longitudinal axis, which merges into a linkage head with an offset, wherein the linkage head is formed for rotationally fixed mounting on an output shaft of a door actuator, wherein a free space for cable routing is formed by the offset. The free space is delimited by the linkage head and by an offset surface of the lever, wherein the lever protrudes up to an imaginary boundary surface, which is defined perpendicular to the longitudinal axis. The offset surface is withdrawn partially from this boundary surface in order to expand the free space.

A braking device for a movable door leaf comprises an electric braking motor to damp movement of the door leaf; a motor shaft coupleable with an axis of rotation of the door leaf; and a control unit to control the electric braking motor. A generator provides power to the control unit. A continuously variable transmission unit between the axis of rotation of the door leaf and either the motor shaft of the electric braking motor or the separate generator is controlled by a mechanical control such that the motor shaft of the electric braking motor and/or the separate generator, can be driven at a rotational speed independent of the rotational speed of the rotational axle of the door leaf. Also included is a door closer, having a rotatable door closer axis, coupleable with a door leaf, cooperating with a mechanical energy storage device, and a correspondingly designed braking device.
