Problems solved by technology

One problem in this case is that the top rail has to be manufactured to be type specific for different door models
If there is any inaccuracy in the fixing points, completely new parts must be ordered for the installation site, which delays the time-critical installation process
A problem is also the cost of manufacturing the top track and roller guides, since they are difficult shapes to make from steel and have parametric fixed points

Embodiment Construction

[0018] figure 1 and figure 2 One frame beam 1a according to the invention is shown supporting the top rail of an elevator car door or landing door, as viewed obliquely from above and when zoomed in and viewed directly from the end. The frame beam 1a is a straight elongated profile beam with a cross-section similar to an I-shape and made of a substantially light material such as aluminium. In the middle of the frame beam 1a is a substantially thin web 1b, on its top edge is a top flange 2a, which is wider than the thickness of the web 1b, and correspondingly, on its bottom edge is wider than the web 1b The thickness of the wider bottom flange 2b. In the horizontal direction, the web 1b is located symmetrically in the center of the flanges 2a, 2b, seen from the end, but in different embodiments the web 1b can also be located in another position, asymmetrically in the flange 2a , the center of 2b.

[0019] At the center of the top flange 2a in the horizontal direction is a f...

Abstract

The object of the invention is an arrangement in the door structure of an elevator, which elevator comprises at least an elevator car with doors and door panels (6), landing doors of the landing areaswith door panels (6) and a hanger carriage (5) of each door panel (6), as well as a top track (1) for the doors, supported on which top track the doors are suspended. The top track (1) comprises a separate frame beam (la), which is enclosed for essentially its whole length with a reinforcement structure (8, 9).

Description

technical field [0001] The object of the invention is an arrangement in an elevator door construction according to the preamble of claim 1 . Background technique [0002] In solutions known in the art, elevator car doors and elevator landing doors usually have a suspension beam, ie a top rail, to which the door operator and roller guides for the hanger rollers of the door panels are fastened, suspended The door panel on the hanger rollers moves in the horizontal direction when opening and closing the door. Since in a fire situation the door must remain in place, the top track and roller guides are usually constructed of steel for fire protection reasons. However, the problem with top rails and roller guides made of steel is the weight of the steel, which makes the car structure of the elevator heavier and makes installation difficult. Fixing points, such as holes, are parametrically formed in the top rail for fastening the top rail to the elevator car structure and / or the ...
