Fig. 7 to 9 show the installation of an elevator landing door unit 4 into an elevator landing door base opening 3 in simplified and schematic views. Advantageously, the elevator landing door unit 4 also comprises a frame, not shown in the figure.

Fig. 7 and 8 are shown in the cross-sectional view a-a of fig. 5, while fig. 9 is viewed from the elevator hoistway 6. In fig. 7, the fastening of the landing door unit 4 has just started, and in fig. 8 and 9 the landing door unit 4 has been fastened in place within the thickness of the wall 2 within the landing door base opening 3. Fig. 7-9 show such an embodiment of the invention, where the landing door opens to one side. In this embodiment, the door panels 4a are suspended from the top rail 5 on different sides of the top rail 5 such that a first door panel 4a is suspended by a first support 20 in a first side of the top rail 5 and a second door panel 4a is suspended by a second support 21 in a second side of the top rail 5.

The landing door unit 4 includes an upper opposing portion 19 at its upper edge and a lower opposing portion 19a at its lower edge. In one elevator landing door base opening 3, the number of upper and lower opposing portions 19, 19a is the same as the number of upper and lower fixing elements 9, 14. Advantageously, the landing door unit 4 comprises two upper counter portions 19 and two lower counter portions 19 a. The horizontal distance between the upper opposing portions 19 is the same as the horizontal distance between the upper fixing elements 14, and the horizontal distance between the lower opposing portions 19a is the same as the horizontal distance between the lower fixing elements 9.

The landing door unit 4, which is prefabricated in the factory, is mounted to the base door base opening 3 by first guiding the upper counter part 19 from below to the vertical slot 18 of the upper fixing element 14. When the upper counter part 19 is guided by the vertical groove 18, the landing door unit 4 is pushed upwards and, preferably, at the same time its lower edge is turned towards the elevator shaft 6. The rotation continues until the lower counter-portion 19a reaches the lower fixing element 9. At this point, the lower counter portion 19a is guided to the horizontal slot 13 of the lower fixing element 9 and continues to rotate until the landing door unit 4 is substantially in the vertical position in place. After that the final position of the landing door unit 4 is adjusted in the fixing elements 9 and 14.

Fig. 10 shows in a simplified and schematic view in cross section a-a the elevator landing door base opening 3 according to fig. 5, and the situation where the landing door unit 4 has been fastened in place. In this embodiment the landing door unit 4 is fastened completely inside the elevator hoistway 6, and therefore the structure of the fixing elements 9 and 14 differs from the fixing elements 9 and 14 shown in fig. 2-9. The only decisive difference is that the receiving portion 9b of the lower fixing element 9 extends in the elevator shaft 6, while the receiving portion 14b of the upper fixing element 14 is entirely in the elevator shaft 6. The landing door unit 4 itself can be similar to the landing door unit 4 shown in fig. 7-9.

Fig. 11 and 12 show an upper counting element 19 to be fitted in the upper fixing element 14 of the elevator landing door unit 4. The upper counting element 19 comprises an L-shaped frame 22 having a first flange 22a and a second flange 22b, the first flange 22a and the second flange 22b being perpendicular to each other. The upper counting element 19 is fastened to the upper edge of the landing door unit 4 by a first flange 22a with fastening elements such as screws. The second flange 22b is preferably in a vertical position and comprises a longitudinal vertical slot 25 for adjusting the height position of the landing door unit 4. The slot 25 is equipped with a bolt 24 which is screwed to a fastening element 23, such as a fastening plate.

The width of the fastening element 23 is smaller than the width of the interior of the C-shaped profile of the receiving portion 14b and the diameter of the bolt 24 is smaller than the width of the slot 18 of the receiving portion 14 b. Thus, when installing the landing door unit 4, the fastening element 23 can be placed within the C-shaped profile of the receiving portion 14b in such a way that the bolt 24 is guided by the slot 18. When the landing door unit 4 is adjusted to its correct height position, the fastening element 23 is fixed to the receiving portion 14b by means of the bolt 24, so that the landing door unit 4 maintains its correct height position. The structure of the lower opposing portion 19a may be substantially the same as the structure of the upper opposing portion 19, but may also be different.

The combination of the lower fixing element 9 with the lower counter portion 19a and the combination of the upper fixing element 14 with the upper counter portion 19 make it possible to adjust the position of the landing door unit 4 in three dimensions. This is useful when performing final position adjustment of the landing door.

With the installation method according to the invention, it is possible to install landing door assemblies safely from the landing side. This means that all installation work can be done at the side of the floor 8 without going to the elevator shaft 6.

The installation method according to the invention advantageously has at least the following steps:

the lower fixing element 9 and the upper fixing element 14 are fastened in place in the landing door base opening 3,

the prefabricated landing door unit 4 with its frame is first suspended to the upper fixing element 14 by guiding the upper counter part 19 to the receiving part 14b of the upper fixing element 14,

the lower part of the landing door unit 4 is turned towards the elevator shaft 6, the lower counter part 19a is fixed to the lower fixing element 9,

the landing door base opening 3 or at least the gap at the opening is covered with a stiff protective wall or plate.

It is obvious to the person skilled in the art that the invention is not limited to the examples described above, but that it may be varied within the scope of the claims presented below.
