Abstract:
PURPOSE: A manual water-gate opening/closing device is provided to enhance durability and limit contamination by limiting the corrosion of a water-gate and a main housing. CONSTITUTION: A manual water-gate opening/closing device(100) comprises a water-gate frame(110), a water gate(120) and a driving unit(130). The water-gate frame is installed on a waterway and consists of first and second vertical frames(111,112) and an upper frame(113). The first and second vertical frames are installed to be separated from each other and are vertically extended. The upper frame connects the vertical frames on the upper end. The water gate is installed to be able to lift along the inner surface of the water-gate frame and is formed from aluminum or aluminum alloy material. The driving unit lifts a rack gear(131) and a pinion gear by the rotation of a handle(140) to lift the water gate.

PURPOSE: An opening and shutting device of a smoke ventilation window is provided to install the device in a narrow space using a compact structure, and to draw in/out a chain without a hitch. CONSTITUTION: An opening and shutting device of a smoke ventilation window comprises an outer case, a chain case, a gear case and a driving motor. The outer case forms an exterior. The chain case has a chain and a sprocket(165). The chain is installed in the inner side of the outer case, and opens and closes a door by being connected to the door. The sprocket is connected to the chain, and draws in/out the chain. The gear case has a shaft, and coupled to the chain case. The shaft transfers power to the sprocket. The driving motor transfers the power to the gear case.

PURPOSE: A safety hinge using an inertial action is provided to prevent a door from being closed suddenly by external impact and to heighten durability and economical efficiency. CONSTITUTION: The safety hinge using an inertial action comprises: a primary connector(10) installed on a door; a secondary connector(20) installed on a doorframe to hinge on the primary connector(10); a rotary shaft(30) fixed on the primary connector to rotate on a hinge joint of the connector and coupled with a hanging gear(31); an inertia force generator(50) generating static inertia force if the door rotates at over the standard speed of revolution; a locking unit(80) locking the hanging gear(31) if the static inertia force is generated to stop the rotation of the rotary shaft and the door; and a clutch unit(70) driving the locking unit(80) by inertia force generated by the inertia force generator(50) if the door rotates at over the standard speed of revolution to stop the rotation of the rotary shaft(30).
Abstract:
The invention relates to a spindle drive (10) extending along a center axis (A), configured to be connected to a body of a motor vehicle (100) and to an opening panel (101), the spindle drive (10) comprising an outer tubular housing (4) and an inner tubular housing (5), the spindle drive (10) being movably mounted between -a closed position in which the inner tubular (5) housing is retracted telescopically inside the outer tubular housing (4), and -an open position in which the inner tubular housing (5) is extended telescopically out of the outer tubular housing (4), wherein the spindle drive (10) comprises - a lighting system comprising a first lighting device (1) extending angularly along an angular section of less than 180° around the axis (A), and - a rotational adjustment device (4a) configured to adapt the rotational position of the first lighting device (1) around the axis (A). The invention further relates to corresponding adjusting device (10a).
Abstract:
The invention relates to an enclosure for a drive unit (1) for automating a garage door, wherein the drive unit (1) comprises a connection to a drive rail (4), which is provided with a circulating force-transmission means (19); the enclosure is a two-part housing consisting of a lower housing part (2) and an upper housing part (32, 54), wherein the lower housing part (2) has a straight, flat housing lower face (37), the edge regions (15) of which have rounded portions (8) and adjoining, substantially straight side sections (9), and the upper housing part (32, 54) is placed onto the side sections (9), wherein the outer contour includes transitions (11) in the form of curved profiles, which open towards a straight housing rear face (7), which is substantially parallel to the housing lower face (37), wherein the area of the housing rear face (7) is smaller than the area of the housing lower face (37).
