Abstract:
An industrial sliding door has one or more panel assemblies, each panel assembly having a track panel secured to a header and a swinging panel hinged at the inner edge of the track panel to pivot in either direction about a vertical axis if the swinging panel is impacted by a vehicle such as a fork lift. Both panels can also pivot in at least one direction about a horizontal axis. A rail mounted stationary relative to the doorway at the lower edge of the door holds the lower edge of the door in proximity to the doorway and is disengagable if the door is hit from the opposite side, to permit the door panel assembly to swing about the horizontal axis away from the doorway. The swinging panel is held by a detent in the plane of the track panel in a normal position.
Abstract:
A pivot-action damper which for example dampens the impact effect of the closing movement of doors, furniture doors or flaps displays excellent braking force or damping force, even over small angular regions as a result of an outer cylindrical body which encompasses an inner body which is pivotable in relation to said outer cylindrical body. Between the two bodies there are two chambers, separated from each other by a gap or a throttle position, with said chambers containing a liquid. This liquid is displaced from one chamber to the other as a result of the rotation of the two bodies in relation to each other.
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:
An operation mechanism attaches a movable member to a main body to be rotatable between a first position and a second position. The movable member is held in the first position by a locking device. The operation mechanism includes a base attached to the main body, a contact portion attached to the movable member, and a coil spring having one end fixed to the base, and the other end attached to the contact portion for urging the movable member in the first position toward the second position. A transfer track for the contact portion is formed at the base. By the transfer track, after the movable member in the first position is moved to a predetermined position by a force accumulated on the spring, when the movable member is pushed to the second position, the spring stores a force from the predetermined position to the second position.
Abstract:
A brake assembly for locking a vertical or horizontal slidable sash window or door within a track of a frame is disclosed. The track has an elongated base and a pair of spaced apart, opposed sidewalls extending perpendicular from the base. Each sidewall has an inner shoulder spaced from and parallel to the base. The assembly has a slider body having a central opening extending from a front face of the body to a rear face of the body. The slider body has a side opening in each side of the slider body and being in communication with the central opening. A pair of brake members are provided wherein one brake member is slidably positioned within a respective one of the side openings. A cam has a rear face and a front face, and is adapted to receive a pivot member mounted on either the sash window or door. The cam is positioned in the central opening and is adapted to be rotatable within the opening by the pivot member. The cam, slider body and brake members include cooperative structure for converting rotary motion of the cam into radial movement of the brake members through the side openings and axial movement of the cam and slider body to lock the brake assembly within the track.

Abstract:
A power drive system is adapted for a sliding door mounted on at least one side of a vehicle for sliding movement forwardly and rearwardly of the vehicle. The system includes a reversible motor. A bracket is guided within a guide along a fixed path between the opened and closed positions of the door. An elongated drive member is slidably disposed within the guide and connected to the bracket at one end for driving the bracket along the fixed path. A translator mechanism operably engages with the drive member for powering movement of the door. The translator mechanism can include a rotatable hub, operably engageable with the drive member, a gear transmission for driving the hub, and a clutch mechanism for connecting the motor to the transmission. The translator mechanism preferably has sufficient power to pull the sliding door into a primary latch position with respect to the corresponding portions of a latch mechanism attached to the door and frame defining the door opening. A power striker moves the door into and out of sealing engagement with the frame. A lock mechanism selectively maintains the latch in a locked position. At least one sensor provides an input signal to a control system corresponding to movement of the door, position of the lock mechanism, and position of the power striker for controlling the door drive unit, power striker drive unit, and lock mechanism drive unit in accordance with a program stored in memory.
Abstract:
A combined sliding and pivot window assembly including a plurality of sashes separately pivotally mounted on substantially C-shaped sash support frames that are slidably fixed on rails provided on an outer window frame. The window assembly includes combined sliding and locking mechanisms that allow the C-shaped sash support frames to slide on the rails when the sashes are pivotally closed, or to be locked on the rails when the sashes are pivotally opened, or to be pushed to one side in the outer window frame while allowing all the sashes to be pivotally opened; pivot mechanisms that allow the sashes to be pivotally opened and stay at any desired open position relative to the sash support frames; and elastic two-end locking mechanisms that are mounted in a vertical member of the sashes to lock the sashes at upper and lower ends to the sash support frames simply by laterally shifting an external adjusting key of the two-end locking mechanism. The combined sliding and pivot window assembly is therefore safer and more convenient for use.
Abstract:
The present invention is a compact door coordinator which includes a relatively narrow housing having mounted therein and extending therefrom a lead control lever and a longer trailing control lever. Both control levers are spring biased to extend from the housing when the doors are open. A relatively simple linkage extends from the lead control lever to the trailing control lever for retaining the ladder in its extended position until the lead door contacts the lead control lever. At that point, the lead control lever is pushed into the housing and rotated against the force of a torsion spring, causing the linkage to move and thereby rotating a cam which then releases the trailing control lever allowing the trailing door to push the trailing control lever into the housing to complete the closing process. When the doors are reopened, the force of the torsion springs causes the lead and trailing levers to once again extend from the housing while resetting the cam to retain the trailing lever in its extended position until it is released.
