Embodiment Construction

[0029] Figure 1 shows a view (from the outside) of the door area of ​​an elevator car 1 in a schematic representation;

[0030] The invention will be described in terms of an elevator car door system. However, the description is similarly applicable to elevator hoistway door systems as well.

[0031] Here, the elevator car door system comprises two frame surfaces 2 forming a kind of door frame (elevator car door front) for entering the elevator from the front, two door panels 3 and 4 and a threshold 5 car. The threshold 5 is fixed to the lower front edge of the elevator car by T-grooves 20b and 20c arranged on the left side thereof in FIG. 1 . Two door panels 3 and 4 are opened to the left. The two door panels are telescopic in the process, which means that the faster door panel 3 is retracted behind the slower door panel 4 in the open state, looking out from the inside of the elevator car. For this reason, the threshold 5 also protrudes to the left into the elevator shaft...

Abstract

The invention relates to a door sill with hidden guide and an elevator door system for elevator car door or elevator hatchway; the system has a door with two movably suspended, relatively telescopic door panels glided at the bottom by a plurality of mutually independent covered guides. A plurality of independent guide grooves are combined into the door sill; wherein, a guide groove that is open only to the elevator hatchway that guides the lower end of a faster door panel, whilst another guide groove is open towards the floor of the story or car and guides the lower end of a slower door panel. Another guide groove is open only to the floor of the story or car in the area covered by the door leaf when the door is closed or open. According to the invention, all the door panels are guided at the lower end by the door sill, and the risk that foreign matter enters into the upward open guide groove from the floor of the story or car floor so as to interfere the guide function is nonexistent.

Description

technical field [0001] The invention relates to an elevator door system according to the preamble of claim 1 . Background technique [0002] Modern elevator door systems designed as sliding doors consist of a single door panel suspended translatably at its top in guide rails. The bottom of such a door panel runs in another rail. This bottom rail prevents possible lateral deflection of the door panel. As a rule, the bottom guide rail engages flush in the service surface of the respective associated floor or elevator car floor and has a guide groove open towards the floor surface into which the corresponding door panel guide seat engages. This type of rail often causes malfunctions or problems. This is because the guide grooves that are open upwards and can be accessed from the floor of the floor or the floor of the elevator car are very easily soiled. Moreover, foreign objects (pebbles, cigarette butts, etc.) often enter the guide grooves, and some people even insert thes...
