Embodiment Construction

[0012] The aforementioned objects are achieved by a manufacturing process for the sills 1, 1' of elevator doors, which manufacturing process includes the steps of providing at least one support element 2 and an upper profile 4 and a step of connecting the support element 2 and the upper profile 4, the upper profile along the main The direction of extension X extends and defines at least one side surface 6 of the first longitudinal groove 8 for slidingly receiving the elevator door.

[0013] According to an advantageous embodiment, the threshold 1 , 1 ′ comprises a single support element 2 , preferably in the form of a profile extending along or parallel to the main direction X of extension.

[0014] According to a preferred variant, the support element 2 has a substantially "L"-shaped cross-section, that is, the first element arms 34 and the second element arms 36 are arranged in an incident (intersecting, angled) manner relative to each other, for example substantially At rig...

Abstract

A sill (1, 1′) for a lift door is manufactured with a method that includes the steps of providing at least one support element (2) and an upper profile (4) that defines at least a boundary surface (6) of a first groove longitudinal (8) for slidingly receiving a lift door. The support element (2) and the upper profile (4) are joined, placing a first demarcation profile (10, 10′) alongside the upper profile (4), so that a boundary surface (12) of the first demarcation profile delimits part of the first longitudinal groove (8). A sliding transversal cross-section of the first longitudinal groove (8) is adjusted by approaching / distancing the boundary surfaces (6, 12) and, having obtained a desired sliding transversal cross-section, constraining the mutual position of the first demarcation profile (10, 10′) and of the upper profile (4).

Description

technical field [0001] The invention relates to a process for the manufacture of elevator door sills, and elevator door sills manufactured, for example, according to the aforementioned method. Background technique [0002] Document GB2387164 by the same applicant discloses a door sill made of metal and the associated manufacturing method. [0003] The known system presented in this document mainly has the disadvantage that the groove serving as the guide for the door is obtained by a series of longitudinal bends of the same profile, such bends having to be carefully executed so that the connection with the sill Other components can be geometrically coupled satisfactorily. [0004] Since each bend involves unavoidable machining errors, it is not uncommon to have difficulties with the assembly of the different parts, the consequent increase in production costs, and the sliding away of the sill after it is in place. Contents of the invention [0005] The present invention i...
