Abstract:
A locking arrangement for a door system of a transit vehicle includes a combination of a lock mechanism and an electromagnetic brake. The lock mechanism enables positive locking of at least one door but does not require substantial contact between moving and stationary lock elements. The lock mechanism is connected with the manual release means for door opening during an emergency. The electromagnetic brake maintains door seal compression in the closed and locked condition which improves sealing capabilities and provides for reliable lock mechanism operation. Such combination provides locking redundancy and meets various requirements regarding annunciation and manual release operation.
Abstract:
A height adjustment assembly connecting an elevator door to an elevator door hanger comprises a door bracket, a plurality of door clip receiving sections and corresponding number of door clips. Each door clip comprises upper and lower fins, side fins, and an oblique slot disposed centrally between the fins. Each oblique slot is aligned with an aperture in the receiving sections, and the upper and lower fins slidably engage corresponding slots in the receiving sections. A fastener inserted into the oblique slot in the door clip and the aperture in the door bracket holds the clip and the bracket onto the door hanger in a friction hold mode. The height of the door may be adjusted by moving the door clips laterally in the slots.
Abstract:
A slider for a guide rail of a window lifter includes a guide section configured to be disposed in the guide rail, a sliding section configured to be disposed in the interior of a holding track for a windowpane and a connecting section linking the guide section and the sliding section. The guide section, sliding section, and connecting section are integrated together into a single unitary piece.
Abstract:
A slider (10) is provided for use with an elongated channel (12) having a pair of spaced apart side walls (14, 16) interconnected by a base wall (18) and an upper wall (20, 22) projecting from each side wall spaced from and generally parallel to the base wall. The slider has a body portion (30) defined by a top surface (32), bottom surface (34) and plurality of side surfaces (36) interconnecting the top and bottom surfaces. The slider also has a plurality of axial slots (42) extending between the top and bottom surfaces adjacent each side surface and a plurality of lateral slots (52) extending between each of the side surfaces and the respective axial slot (42) for allowing the side surface to flex and bias the slider between the side walls of the channel (12). The slider (10) further has a plurality of raised ridges (44) projecting from each of the top and bottom surfaces for flexing and biasing the slider between the upper walls and the base wall of the channel. Finally, the slider includes a plurality of semi-spherical embosses (48) extending from the top and bottom surfaces for slidably engaging and guiding the slider between the upper walls and the base wall within the channel (12).
Abstract:
A movable door mounting assembly includes a stud assembly and a trolley assembly having a spring-biased cam piece that pivots between a normal position, which allows the trolley assembly to move freely on the track, and a locked position, which causes a locking surface on the cam piece to frictionally engage with a top surface of the track and hold the trolley assembly in place while the door is being hung. A catch in the stud assembly engages with the cam piece when the mounting assembly is fully assembled. Inserting the stud assembly into the trolley assembly, releases the cam piece from its locked position and, at the same time, positions the catch so that it engages with the cam piece when the door is hung.
Abstract:
A device for supporting and guiding the movement, in both a longitudinal direction and a lateral direction, of a sliding panel in a frame structure by using guide tracks and vertically adjustable guide castors. The vertical position of the sliding panel is adjustable with the aid of a bogie-based carrying wheel mechanism. A locking mechanism with a specially designed striking plate assists longitudinal and sideways movement of the sliding panel into a locking position for locking of the sliding panel.
Abstract:
A door truck which has a one piece frame and plastic wheels for operation in an overhead track for supporting a door in which the wheels are mounted to the frame with barrel nuts and a threaded stud. The frame has a door supporting portion through which a pendant nut can be extended with its head mounted upwardly or downwardly so as to support a door.
Abstract:
A pulley cradle arrangement for a screen doors, in particular, having a pulley cradle receptacle (23) that is inserted from above into a hollow frame section (1) and is clamped there. The pulley cradle receptacle (23) holds the pulley cradle support (25), inside of which the pulley cradle (27) and its running rollers (28) can be shifted vertically by means of a knurled screw (89). All parts can be pushed together without the use of tools and snap together by means of elastic holders. The pulley cradle (27) can be removed from the pulley cradle support (25) by pushing on its front surface and thus the sliding door can be removed from the guide rails.
Abstract:
Door operator for opening, closing and locking at least one door panel on a transit vehicle. The door operator has at least one base portion for mounting on the vehicle and at least one fixed support member attached to the base portion. The door operator has door hangers for attachment of the door panel to the fixed support member and moveable door support members attached to the door hangers. The moveable door support members engage the fixed support member to support the door panel while permitting opening and closing motions of the panel. The operator includes at least one door drive having a base mounted portion and a hanger mounted portion engaging the base mounted portion to be moved thereby to move the panel in opening and closing directions. The operator has a lock for securing the door panel in a closed position, the lock having a lock shaft which includes at least one primary lock device for preventing motion of the base mounted door drive portion and at least one secondary lock device engaging one of the door hangers. The lock includes a lock shaft engaging mechanism which rotates the lock shaft to a locking position when the door panel is closed. The lock also has an unlocking actuator for unlocking the door panel, the unlocking actuator having a moveable portion connected to the lock shaft to rotate the lock shaft to the unlocking position.
Abstract:
This device comprises at least one clamp (7) with two jaws (8) for gripping the window (2), these jaws being designed to grip the lower edge (2a) of this window, a back plate (9) laterally extending from one jaw approximately in the plane thereof, a slider (6) which is shaped so that it can slide on a window lifter guide rail, and a fastener for securing the slider and the back plate; formed in the slider is a recess (14) designed to take the back plate (9), the back plate has lateral tabs (16, 17) designed to to slide as far as an abutment position along retaining ramps (18, 19) formed in the slider to the side of the recess, and an elastic tongue and opening (26, 27) are provided for locking the back plate in its position in abutment on the slider. This device is easy to assemble and takes up a small amount of space in the transverse direction.
