Abstract:
The invention relates to a drive device (20) for a sliding panel (2) of a sliding window (1) or sliding door, comprising a spindle (24) which is rotationally mounted in fixed bearings (26, 27) and driven by a motor (22). On said spindle an axially mobile nut (28) is arranged which is prevented from rotating by a fixed guide element. The nut is connected in a driving manner to the sliding panel (2), for example via a driver (29). At least one mobile bearing part (34, 35), which is arranged between the fixed bearings (26, 27), can be freely displaced in an axial direction along the spindle (24) and is prevented from rotating so that it is moved by the spindle nut (28) when said nut is adjusted.
Abstract:
A power drive moves a movable closure (D) between an open position and a closed position with respect to a portal defining a passage through a barrier. The power drive can include an elongated drive member (34) connected to the movable closure and a ball nut drive assembly (64) for selectively moving the drive member longitudinally. The elongated drive member (34) can be a compound drive member having at least one gear or tooth-like member extending helically around in uniformly spaced turns about a core of the drive member to form a rigid or resilient screw-like portion (88) capable of being driven by operable engagement with the recirculating ball nut drive assembly (64). A flexible portion, such as a push/pull cable (90) can be attached to one end of the screw-like member to allow the power drive to move a movable closure along a curved or other non-linear path.
Abstract:
A refrigerator appliance may include a cabinet, a door, a door opener, and a controller. The door opener may be attached to a cabinet and include a casing, a push rod, and a position sensor. The controller may be in operable communication with the door opener and configured to direct an opener operation. The opener operation may include directing the push rod to a retracted position, detecting the door in the closed position following directing the push rod to the retracted position, directing the push rod forward from the retracted position following detecting the door in the closed position, monitoring sensor output at the rod-load sensor while directing the push rod forward, detecting contact with the door while monitoring sensor output, and halting the push rod at a partially extended position in response to detecting contact.
Abstract:
A sliding closure assembly includes a frame assembly, at least one sliding closure panel, a second panel, and a powered actuator. The frame assembly has a first track portion, a second track portion, and a catch portion. The sliding closure panel slides within the first track portion of the frame assembly. The second closure panel is adjacent to the at least one sliding closure panel and is positioned within the second track portion of the frame assembly. The powered actuator assembly is positioned adjacent to the second panel and entirely within the second track portion. The sliding closure panel slides within the first track portion of the frame such that an opening is formed through the sliding closure assembly when the sliding closure panel is in the opened position and the opening is closed when the sliding closure panel is in the closed position.
Abstract:
A scissor drive includes two legs which can be pivoted relative to one another about a pivot axis, each having a longitudinal axis and designed to be connected to an external component, and a motor/gear assembly that drives the relative pivoting movement of the two legs. The first leg includes a housing that is hollow at least in portions, a cavity defined in the hollow housing extending at least in portions along the longitudinal axis of the first leg, and the motor/gear assembly being received in the housing of the first leg at least in portions in the portion of the cavity that extends along the longitudinal axis of the first leg.
Abstract:
Actuating drive for moving a flap of an item of furniture, comprising: a housing, at least one actuating arm, which is pivotably mounted on or in the housing, for the moving flap, a spring apparatus for applying force to the actuating arm, a transmission mechanism for transmitting a force of the spring apparatus onto the actuating arm, an adjusting apparatus by means of which a lever geometry of the transmission mechanism and/or the force of the spring apparatus, which force acts on the actuating arm, can be variably adjusted, a damping apparatus by means of which a movement of the actuating arm can be damped by a damping power in the event of a damping stroke, wherein the adjusting apparatus is coupled to the damping apparatus by means of a coupling apparatus, the position of the damping apparatus relative to the housing and/or the damping stroke of the damping apparatus and/or the damping power of the damping apparatus can be variably adjusted.
Abstract:
A corner fitting for a door element, in particular for a glass door element, include a first fitting element and a second fitting element, which each include, at least sectionwise, a locating portion. The locating portion includes an intermediate layer able to contact the door element. The fitting elements delimit the restraining area, wherein a holding element is in operative connection with a connecting element, which serves for supporting the door element on a center of rotation and/or an axis.At least one variably adjustable distancing element is disposed between the fitting elements outside the locating portions, wherein the distancing element forms a counter-bearing to the locating portions and the door element, which can be restrained in the restraining area.
Abstract:
In an aspect, a swing door actuation system is provided for moving a door about a vertical axis between open closed positions relative to a vehicle body. The system includes a housing connectable to one of the swing door and the vehicle body, an extensible member that moves relative to the housing, and connects to the other of the swing door and the vehicle body, a motor connected to a gear train that is non-backdrivable, and a normally engaged clutch. The motor is operatively connected to a clutch input end through the gear train. The output end is operatively connected to the extensible member. The clutch is disengageable to disconnect the motor from the extensible member. The clutch has a slip torque that is sufficiently high to prevent movement of the door when the door is exposed to less than a selected external torque and the motor is stopped.
Abstract:
Provided is a fitting adjustment structure for a lid in which, before a frame and a lid are incorporated into an opening portion, a height of a stopper can be adjusted with the lid being closed, to thereby eliminate the need for adjustment after the incorporation. The fitting adjustment structure for the lid includes: the opening portion formed on a panel; the lid which turns to open and close the opening portion; and the frame which is placed along a periphery of the opening portion, and supports the lid, in which: a screw hole is pierced in the frame; a stopper having an upper surface which abuts against a rear surface of the lid in a closed state is screwed with the screw hole; and a turning operation portion engageable with a rotating tool is provided at a lower end of the stopper.
