Embodiment Construction

[0039] With reference to the accompanying drawings, reference numeral 1 designates a frame for elevator landing doors, comprising two substantially parallel lateral door casings 2, 3, a cross bar 4 and a sill 5.

[0040] The crossbar 4 is fixed to the upper ends 2 a , 3 a of the lateral door pockets 2 , 3 by first fixing means 6 .

[0041] The sill 5 is fixed to the lower ends 2b, 3b of the lateral door casings 2, 3 by second fixing means 7.

[0042] The frame 1 surrounds an opening 100 having a pre-established extent.

[0043] Initially, the upper end 2 a , 3 a of each lateral door pocket 2 , 3 has a groove 8 shaped to support one of the two ends 4 a , 4 b of the cross bar 4 .

[0044] Preferably, the groove 8 is substantially L-shaped, such as Figure 4 visible in .

[0045] Thanks to this groove 8, the upper ends 2a, 3a of the crossbar 4 and the lateral door casings 2, 3 can slide against each other to allow the lateral door casings 2, 3 to move towards and away from eac...

Abstract

Frame (1 ) for landing door of an elevator defining an opening (100), comprising: two lateral jambs (2, 3) substantially parallel; a crossbar (4) fixed to upper ends (2a, 3a) of the lateral jambs (2, 3) by first fixing means (6); a sill (5) fixed to lower ends (2b, 3b) of the lateral jambs (2, 3) by second fixing means (7), in which the lower end (2b, 3b) of each lateral jamb (2, 3) has a series of through holes (14) aligned along the prevalent extension of the lateral jamb (2, 3), the second fixing means (7) comprising at least one support bracket (13) of the sill (5) at the lower end (2b, 3b) of each of the lateral jambs (2, 3) and a screw or rivet (15) which, when joining the corresponding support bracket (13) to the lower end (2b, 3b) of the lateral jamb (2, 3), crosses one of the aligned through holes (14) so that the sill (5) is located at a pre-established height with respect to the lateral jambs (2, 3).

Description

technical field [0001] The present invention relates to frames for elevator landing doors. The frame is applied to landing doors with central opening and horizontal (telescopic) opening. Background technique [0002] As is known, each landing door consists of a frame consisting of two lateral door pockets, a crossbar (sometimes also denoted "upper door pockets") and a lower profile formed by the Combination of combination and sub-sill. [0003] The dimensions of the elements making up the frame are chosen so as to accommodate a good set opening of the door. Thus, it is necessary to have four elements for each elevator installation, sized to match the specific opening required. [0004] In order to meet this demand, manufacturers are forced to manage the production of "to-size" components according to the dimensions required at the time of a specific installation. [0005] Custom management of each order results in longer wait times for end users and ultimately higher ope...
