Abstract:
A control device for doors of an elevator system comprises a coupling system for coupling a car door with a landing door and operable to open and close the car door and the landing door at a landing position of the car. A car door locking mechanism locks the car door shut and permits the unlocking of the car door in response to the coupling system reaching an opening position. A blocking device blocks the coupling system from reaching the opening position when outside the landing position of the car.
Abstract:
The elevator has a car movable vertically within a shaft between lower and upper end positions and a drive system coupled to a traction system for controlling movement of the car. A limit switch which is open when the car is in a selected distance range from one of the end positions. The limit switch forms part of a power line supplying power to the drive system for controlling movement of the car in a direction towards that end position in an inspection operation. Thus movement of the car is prevented only in that direction when the car is in the selected distance range in an inspection operation.
Abstract:
The invention relates to a safety lock (1) for an elevator landing door detecting intrusion of a person in the shaft through the landing door, activating a bistable switch (21) through its spindle lever (11) putting the elevator into safe operation when the landing door is opened by turning the corresponding key, it being impossible to reset the switch (21) manually from the inside of the shaft, which comprises a device (17) fixing the lock in the open position with the door open, that is released when the door is closed such that the switch (21) can be reset by turning the lock (1) in the closing direction of the door in which the key is turned in the opposite direction to the opening direction, the switch (21) being reset mechanically by a mechanical means connected to the spindle lever (11).
Abstract:
An elevator system includes guide rail mounted machine (16) and a sheave assembly( 32) that accommodates a guide rail (38) within a hoistway. The inventive sheave assembly includes individual sheave portions (54) rotatable along a common axis. At least two of the sheave portions are spaced apart along a shaft (50) and a portion of the guide rail extends toward the axis beyond a plane formed tangent to the outside diameter of the sheave portions.
Abstract:
Device for assembling two metal sheet parts (1, 3) together at one or more fastening points, particularly for elevator landing door frame elements, characterized in that said two parts (1, 3) are designed so that a first one (1) of the parts bears a clip element (5) at said fastening point and the other or second part (3) has a matching slot (13) complementary of the clip element (5) within a fitting clearance, wherein the clip element (5) is adapted to enter said slot (13) at said fastening point in a first insertion displacement (T1) followed by a translation travel (T2) of one part (1) with respect to the other (3) for assembly, and in that said parts (1, 3) are designed to include also at least one locking element (7) to arrest the translation travel (T2) of the clip element (5) in the corresponding slot (13).
Abstract:
The invention relates to a set of landing doors (19) and elevator car doors (21) as a replacement for existing swing doors without requiring any substantial masonry work, any change in the structure of the car or in the displacement of the latter, the space between the car frame (13) and the landing access opening frame (3) being of 125 mm at the most, characterized in that it comprises a set of landing doors (19) positioned just behind the landing access opening frame (3) and provided with a set of one panel and two telescopic panels with a central opening, the total thickness of which is reduced, and a set of car doors (21) mounted on the elevator car, with a configuration analogous to the set of landing doors (19) and intended to come face-to-face with the latter, within the space (9'), at each building storey landing, in said space of 125 mm between the car frame (13) and the landing access opening frame (3).
Abstract:
The invention pertains to a supporting lintel for elevator doors with a telescopic opening, which doors include two panels (5) moving in the same direction and at different speeds, characterized in that it is provided with a single track for guiding (11) the panels, which are each suspended from said track (11) by means of an upper carriage (7) with two distant roller rollers (9), a carriage roller (9) of a panel being positioned between both carriage panels (9) of the other panel and both respective carriage rollers (9) of the panel being spaced apart on the track (11), offset from both carriage rollers (9) of the other panel on the same track (11), by at least a distance sufficient for allowing the opening and the closing of the car doors.
