A door closer system is provided that includes a motor, a spring, a reduction gear set, and a rack and a pinion mechanism. The spring and pinion may be coupled to the rack, and the pinion may be selectively coupled to the gear set. The motor may be selectively mechanically coupled to the gear set. The pinion may rotate in a first direction via the rack as the spring is compressed in a second direction opposite the first direction as the spring is expanded. The motor is operable to rotate and act upon the pinion through the gear set, thereby rotating the pinion in the second direction and assist the spring in closing the door.

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 hinge assembly for an associated appliance door includes an arm and a lever pivotally connected to the arm. The lever and arm are adapted to pivot relative to each other about a main pivot axis between a first position that corresponds to a closed position of the associated appliance door and a second position that corresponds to an opened position of the associated appliance door. A slide link is located adjacent the lever. A damper engagement structure is connected to the slide link. A biasing system urges the arm and lever toward the first position. A damper system includes a damper that damps pivoting movement between the arm and the lever for at least part of the movement between the arm and the lever when the arm and lever pivot relative to each other from the first position toward the second position.

A door closer mechanism includes a base attached to a door frame, a housing attached to a door panel and a groove formed in the housing, a lever includes one end slidably engaged with the base and another end connected to the housing with a pivot axle, a rotary member is pivotally connected to the housing with the pivot axle, a shaft is slidably engaged in the housing and pivotally connected to the rotary member with a pivot pin, and a spring biasing member is disposed in the housing and engaged with the shaft for applying a spring biasing force onto the shaft and for biasing the shaft toward one end portion of the channel of the base.

The present invention relates to a door operator system (1) for opening and closing an opening (2), comprising a drive unit (10), a door frame (3) and a door (8), wherein the drive unit (10) is mounted to the door (8) and adapted to move the door (8) between an open (O) and closed position (C), the door frame (3) comprise at least a first frame section (4) adapted to be mounted at a first side (5) of the opening (2), a second frame section (6) adapted to be mounted at a second side (7) of the opening (2), a first track unit (31) moveably connected to the first frame section (4), and a second track unit (32) moveably connected to the second frame section (6), the door (8) is at a first side moveably connected to the first track unit (31) and at a second side moveably connected to the second track unit (32), wherein the door frame (3) is adapted to move the door (8) between the closed position (C) and an intermediate position (I) and to guide the door (8) between the intermediate position (I) and the open position (O).

A hold lock mechanism for a vehicle door, the hold lock mechanism including a grip assembly configured to be mounted on a vehicle body, the grip assembly including a pair of grip members configured to releasably grip a door component and a hook provided on at least one of grip members, and a release assembly mounted on the door component, the release assembly including a release member configured to releasably engage with the hook.

A cinching system includes: a profile configured to determine a first time series of target values for cinching a closure closed; an adjustment module configured to determine an adjustment value based on at least one operating parameter; an adjusting module configured to generate a second time series of target values for cinching of the closure by adjusting at least one of the target values of the first time series based on the adjustment value; and a power control module configured to: apply power to a cinching motor when the closure is partially closed, where the cinching motor is configured to cinch and fully close the closure; and based on a comparison of a measured value of the cinching motor and one of the target values of the second time series, selectively one of: decrease power applied to the cinching motor; and disconnect the cinching motor from power.

An example retention assembly has a motor assembly and a self-locking worm drive coupled thereto. A cam is fixed to a worm gear of the worm drive. The retention assembly has an actuation shaft including a follower. The actuation shaft is displaceable over a displacement range via rotation of the cam. The retention assembly has a securement member with a securement member follower, the securement member coupled to a portion of the actuator shaft. The retention assembly has a housing cam included as part of the retention assembly housing and against which the securement member follower is biased. The securement member are in an open state when the actuation shaft is in a first position. The securement member swings outward to a retaining position as the actuation shaft is moved to a second position.

A sliding door includes a frame and a slow close assembly. The frame is positioned along at least a portion of the sliding door and includes a protrusion configured to slide along with the sliding door. The slow close assembly is repositionable between an outward position and a compressed position. The slow close assembly includes a slow close mechanism, a spring, and a soft close latch. The slow close mechanism is laterally positioned within the slow close assembly. The spring is positioned at an end of the slow close assembly and provides an outward force onto the slow close assembly in an outward direction substantially perpendicular to the lateral direction. The soft close latch is configured to engage the protrusion as the protrusion slides along with the sliding door. The spring biases the slow close assembly into the outward position when the latch is not interfaced with the protrusion.
