Problems solved by technology

[0003] Drives currently used for elevator car doors generally protrude outside the car roof and require a relatively large amount of space, which may limit the volume of the car, and due to the roof of the car and the required residual Space requires higher elevator shaft
Plus, if the system fails, repairs must be done indoors

Embodiment Construction

[0023] As shown in FIG. 1, the drive device of the present invention represents an application for an intermediate opening of two elevator car doors 1 . It can be equally applied to other types of car door openings.

[0024] The drive comprises a toothed belt 3 which runs along a support web 5 of the car door 1 at the upper part of the car. This belt 3 is driven by a motor pulley 7 at one end of the lintel 5 and is received at the other end by an idle return pulley 9 at the other end. The belt 3 is formed as a longitudinal loop having two adjacent ends 11 secured to a given door by fixing brackets. Another door is secured to the other loop end of the belt.

[0025] Each door 1 is guided in the direction of horizontal movement ( FIG. 3 ) by upper support rollers 13 and lower counter rollers 15 rolling on a rail 17 arranged at the lower part of the web 5 .

[0026] The motor pulley 7 is driven by a flat 24 volt low voltage direct current (d.c.) motor 19 . Such as figure 2 T...

Abstract

The invention concerns a compact drive device, especially for the translation of elevator booth doors, the speed reducer and motor unit used and the support lintel for the doors of the equipped elevator booth. The compact drive device of elevator booth doors, of the type with translation of the doors (1) with the aid of a belt (3) driven in the doors upper support lintel (5) joined to said doors (1), is characterised in that it includes a flat d.c. electric motor (19) associated with a speed reducer placed adjacent to the motor (19), and a drive pulley (7) of relatively large diameter and adapted to cover at least one portion of the width of the reducer so as to reduce the width of the unit constituted by the back-geared motor (19) and the pulley (7), this back-geared motor (19) and pulley (7) unit being fixed to said upper lintel (5) inside the latter.

Description

technical field [0001] Compact drives especially for translating elevator car doors, the gear and motor units used and the supporting lintels. Background technique [0002] The invention relates to a compact drive, in particular for translating elevator car doors, a flat electric motor with associated reduction gear used, and a support web for the assembled elevator car door. [0003] Drives currently used for elevator car doors generally protrude outside the car roof and require a relatively large amount of space, which may limit the volume of the car, and due to the roof of the car and the required residual Space requires a higher elevator shaft. Plus, if the system fails, repairs must be done on the roof. Contents of the invention [0004] The object of the present invention is to solve these disadvantages and to provide a compact drive for elevator car doors and of the door translational type, said translation being carried out by means of a belt supporting the linte...
