An exemplary door closer includes a body, a regulation screw, and an indicator. The body includes a surface and a cavity extending from the surface into the body, and the cavity includes an internal threading. The regulation screw is mounted in the cavity and includes an external threading engaged with the internal threading. The indicator is engaged with the regulation screw and positioned at least partially within the cavity. The indicator is positioned to project beyond the surface when the regulation screw is withdrawn to a reference position relative to the body.

A door system includes a controller for controlling the door system. A user computer system transmits information to the controller over a wireless connection to modify operating parameters for controlling the operation of the door system. During installation of the door system sensors may be utilized to determine if the door system has been installed properly. The sensors may be used to identify if the door system is mounted level and plum, and to review the movement, vibration, speed, acceleration, force, or the like of the sensors, and thus, the components to which the sensors are operatively coupled in order to make adjustments to the door assembly. Furthermore, the operating parameters of the installed door system, may be cloned and provided to other door systems in order to quickly clone and distribute the operating parameters of one or more door systems to one or more other door systems.

A combination door guide and protector can be used to safely and easily attach or remove vehicle doors. A set of two guides can be used for each door. Each guide can include a forward curved portion and a second curved portion that extend outwardly away from a body and form a groove. Each guide also includes a crenellated void. A body can connect the two guides and can extend away from each side of the curved portions to provide protection to the vehicle frame and body. The crenellated voids can be placed on top of weldments of hinge pin receivers located on the vehicle body frame. Hinge pin housings on the vehicle door can be slid within the groove until hinge pins on the door engage with the hinge pin receivers. The combination device makes it easier to align the hinge pins with hinge pin receivers.

Disclosed herein is a drive arrangement for motor-operated adjustment of a closure element in a motor vehicle having at least one drive with a drive motor, and a drive controller. The closure element can be driven in the motor-operated adjustment mode by the drive motor in the closing direction and in the opening direction between a closed and an open position. The drive is non-self-locking and has a sensor, in particular a Hall sensor, for sensing the drive movement. The drive controller monitors the sensor signals for a fault state, and when a fault state is sensed initiates an emergency braking and/or stop mode. The drive arrangement comprises two drives each with a sensor for determining the respective drive movement. To detect drive-fault-induced slamming shut of the closure element, the drive controller correlates the sensor signals of the two sensors, in particular compares said sensor signals.

A slide-and-swing wing system includes at least one rail profile. At least two wings, each displaceably mounted in the at least one rail profile via two support elements The at least one rail profile has a lateral outlet opening for unlatching a support element of a wing. One wing functions as a door leaf which, with all other wings in the latched state, is pivotable into the remaining opening. A closure mechanism makes it possible to prevent the door leaf from being opened and includes a drive, and also an operating part, via which the drive can be actuated. The door leaf is displaceable, via the drive, in the rail profile in the direction of the adjacent wing to such an extent that no support element of the door leaf is aligned with the outlet opening, thereby preventing a support element from coming out through the lateral outlet opening.

A door hinge has first and second leaf assemblies. The first assembly is formed with a longitudinal guide groove. First and second links are connected to each other for relative pivoting about a vertical axis. The first link is pivoted in a longitudinally displaceable slide in the groove. This slide has a length longitudinally of the guide groove and a width transversely of the guide groove. The ratio of the length to the width of the slide is at least 2:1.
