Abstract:
A negative-pressure smoke-guiding fireproof building structure includes at least one vertical smoke discharge flue arranged in the building and in fluid communication with a transverse smoke discharge flue arranged in upper space of each floor. At least one natural air inlet window having a door and at least one smoke-gas discharge window having a door are arranged in a wall of each independent room off each floor. The doors normally seal the windows in a closed position and are capable of automatically opening at a fire hazard. The smoke-gas discharge window is in fluid communication with the transverse smoke discharge flue. With a simple structure, the building structure effectively prevents fire spreading to peripheral adjacent rooms when one room in the building catches fire, so as to prevent a larger fire hazard.

Abstract:
Support and operating device for sliding doors, in particular for wardrobe cabinets, wherein the doors (6) are moved from a closed and lowered position, to an open and raised position, shifted forward in relation to the closed doors, and vice versa. The device comprising one upper group of component parts and one lower group of component parts for each door (6), suitable for determining the movement of the door in such a way that it is always kept in its correct parallel and orthogonal position in all the shifted positions thereof.
Abstract:

Abstract:
The present invention discloses a drive apparatus for a rotor of a revolving door, wherein the drive apparatus comprises a drive device, which is motion-coupled to the rotor via a drive belt. The drive apparatus further comprises a tensioning device for tensioning and deflecting the drive belt, wherein the drive belt runs via the drive device and via the tensioning device. The tensioning device and/or the drive device are mounted with a variable distance between one another, so that an extension of the drive belt caused by acceleration or deceleration of the rotor is compensated by varying the distance between the tensioning device and the drive device.
Abstract:
An auto-closing device has a base, a cylinder, a slider, a spring and an adjusting device. The adjusting device is connected to an end of the spring opposite to the slider and has an adjusting frame and an adjusting bolt. The adjusting frame has a first end connected securely to the spring and a second end provided with a threaded hole. The adjusting bolt is mounted rotatably on the base and is screwed into the threaded hole in the adjusting frame. Accordingly, when the adjusting bolt is rotated, the adjusting frame is moved relative to the body so that the pulling force provided by the spring is adjusted to fit with different door panels with different weights.
Abstract:
A hinge for appliances includes a lever and a box-shaped body having a bottom wall and two side walls. The lever and the body, one of which is fixable to a frame of the appliance and the other to a door, are tiltably hinged to each other by a first pin to make the door movable between open and closed positions. The hinge includes an elastic mechanism located at least partly inside the body for producing an elastic reaction force which opposes opening of the door, a connecting rod hinged to a first end of the lever, a tie rod hinged to the connecting rod and connected to the elastic mechanism, and a pivot pin for the tie rod and the connecting rod, slidable with its ends in respective guides formed in the side walls of the body when the door is opened and closed.
Abstract:
A sliding door mechanism includes an upper slide rail and a lower slide rail fixed to a vehicle side body structure. An upper slider is associated with the upper rail, and a lower slider is associated with the lower rail. An upper link includes a control arm pivotally connected to both the upper slider and a vehicle door. A lower link includes a control arm pivotally connected to both the lower slider and the vehicle door. A control mechanism is operatively associated with a selected one of the upper link and the lower link. The control mechanism includes a first control fixed to the vehicle side body structure and a second control fixed to the control arm of the selected link. Movement of the second control is based on predetermined structural constraints associated with the first control. The control mechanism controls rotation and translation of the upper and lower links.
Abstract:
A device for moving sliding doors may include a rectilinear guide mountable along the width of an opening reclosable by means of a door, a first bogie slidably movable along the rectilinear guide and connected to a connecting element solidly securable to the door, an auxiliary bogie connected to said connecting element, mounted on the first bogie and free to run along a direction substantially perpendicular to the rectilinear guide, an auxiliary guide in which is engaged the auxiliary bogie, a second bogie slidably movable along the rectilinear guide. The device may include a rotatable arm pivoting on the second bogie and having an end hinged to the connecting element. The rotatable arm is movable between a first position, in which it lies substantially aligned with the rectilinear guide, and a second position, in which it lies substantially perpendicular to the rectilinear guide.
Abstract:
An automotive vehicle includes one or more swinging doors which may be immobilized in a number of positions, so as to allow the doors to be used to assist passengers upon entering and leaving the vehicle. The motion of the door may be damped, or stopped entirely, either at the discretion of a vehicle occupant, or automatically, in the event that the door is driven by external forces to swing at a high rate.
