Embodiment Construction

[0038] 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.

[0039] 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 .

[0040] The sill 5 is fixed to the lower ends 2b, 3b of the lateral door casings 2, 3 by second fixing means 7.

[0041] The frame 1 surrounds an opening 100 having a pre-established extent.

[0042] The upper end 2 a , 3 a of each lateral door casing 2 , 3 has a groove 8 shaped to support one of the two ends 4 a , 4 b of the cross bar 4 .

[0043] Preferably, the groove 8 is substantially L-shaped, such as Figure 4 visible in .

[0044] 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 each other, i....

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); a sill (5) supported by support brackets (13) which are fixed to the lower ends (2b, 3b) of the lateral jambs (2, 3) at a pre-established height that is adjustable with respect to the ground or floor; a reinforcement plate (12) for each of the two ends (4a, 4b) of said crossbar (4).

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...
