Abstract:
Rotary locks used on transit vehicle doors (2) when opened and closed by a rotating helical door drive member (40). In a preferred embodiment, a first lock utilizes a negative thread portion (51) of the helical drive (40). A second lock utilizes a rotating lock pawl (22) and stop (23). The drive (40) and lock can be used to operate door systems with and without separate door hangers. Compensation for camber variations in car structure is provided through the use of spherical mounts or drive member journals (35, 38).
Abstract:
L'installation comprend un bâti allongé (2) supportant un élément mobile linéairement (5) entraîné par une vis ou chaîne relié à la porte à entraîner, et fixé en deux points hauts (9, 11) dont l'un (9) est situé à une extrémité du bâti. Cette extrémité est fixée à un support fixe (9) présentant une découpe verticale dont le fond présente une gorge (17) dont la partie supérieure est limitée par une surface (18) située à une distance déterminée du fond de la gorge (17). La bâti (2) présente une surface d'appui, par exemple un axe (19), et une surface de verrouillage, par exemple un axe (20), situé à une distance du premier axe correspondant à ladite distance déterminée. Le bâti se fixe par une seule personne par accrochage de l'axe inférieur au support puis levage à l'horizontale, ce qui a pour effet de verrouiller automatiquement la fixation.

PURPOSE: A fixture for controlling the horizontality of a window frame is provided to prevent a window frame from sagging by securely supporting the window frame to a wall. CONSTITUTION: A fixture for controlling the horizontality of a window frame comprises upper and lower support portions(10,20) and a nut portion(30). The upper support portion has a support plate(12) and a shaft tube(14) with a male screw. The lower support portion vertically faces the upper support portion and has a fixed plate(22) and a shaft tube(24) with a male screw. The nut portion has upper and lower female screws with different diameters to vertically couple the upper and lower support portions to each other.
Abstract:
An electromotive ventilation window capable of manual operation is provided to manually open/shut the ventilation window in the situation in which the supply of the electricity is suspended. An electromotive ventilation window(100) capable of manual operation is composed of an opening and shutting member which is geared with an operating screw(2) operated by an electric motor and operates a window(120) while horizontally moving in the operating screw, an opening and shutting wire(7) in which a screw thread only is formed in the upside of inner space and both ends are fixed to the window, which is formed in an elliptic shape, is installed to be geared with the operating screw when a solenoid is only operated, and a roller(8) fixed to the center of the window.

Abstract:
PURPOSE: An automatic open a shut apparatus for a gate door is provided to open and shut a gate door without noise and strengthen the durability by a driving shaft and a transfer pipe. CONSTITUTION: In an automatic open and shut apparatus for a gate door, a motor(30) is driven by the signal of a sensor(20) that is installed at the upper part of door frame of gate door, and rotates a shaft of motor in right direction. And at the same time a driving shaft(40) which interlocks with the shaft of motor rotates in right direction. A transfer pipe(50) has a right helical gear groove part in the inside surface to be united with a right helical gear part(41) of the driving shaft. And a door fixing bracket(60) is slid into the opened end transfer pipe.
