Embodiment Construction

[0017] The door suspension system according to FIG. 1 comprises a guide rail support 1 which is connected to a cross pipe 2 of a door frame and arranged above a door or an entrance. This system can be applied to doors, windows, and openings of industrial buildings, houses, elevators, vehicles, preferably, the rail support 1 has a T or L-shaped section. In the position shown in Figure 1, it is the position where the T-shaped section is rotated 90 degrees counterclockwise. The horizontal part of the rail support 1 is actually a hard rigid plate 3 for supporting eg a commercial type linear rail 4 the length of which extends at least the length of the door or is at least approximately equal to the length of the door travel. The rail 4 comprises a cylindrical head 5 and a connecting plate 6 with an extension 7 connected to the plate 3 . An example of a linear guide is the Thomson guide system currently used on industrial linear motors. The door suspension system includes a bracke...

Abstract

A door suspension system includes a rail support attachable to a crosspiece of a door and having a part shaped as a rigid substantially flat plate that supports a rail. A pair of brackets, each having a connector, are attached to support block having an opening in which the rail is partially received. The connectors have a substantially C-profile embracing the flat plate and the rail. A support strip is attached to the connectors and is provided with a connection device for suspending the door of an elevator. A magnetic way is attached to the plate and an elongated primary of a linear motor is attached to the strip in such a manner that the attraction force between the magnetic way and the primary cancels at least partially the weight of the door. The door suspension system further includes a bearing of substantially cylindrical shape with an axial recess. The bearing is mounted in the opening of the support block to guide the rail.

Description

technical field [0001] The invention relates to a door suspension system as defined in claim 1 . Background technique [0002] European Patent No. 0841286A1 discloses an elevator door suspension system for opening and closing elevator doors, which comprises a linear induction motor with a pair of movable motor primary coils, each connected to the hanger of the respective door , and a secondary coil, connected to the upper bracket fixed on the lift car, wherein the above-mentioned secondary coil of the motor includes a vertically arranged flat plate, and the flat plate is made of a metal conductor like copper. In this system, the door panels are guided by individual rails, and the synchronized movement of the door panels is kept by a pair of movable flexible ropes and wheels. [0003] One problem with such elevator door suspension systems with movable flexible cords and wheels is that they are very expensive. Another disadvantage is its stability and maintenance issues. C...
