Problems solved by technology

However, in order to strengthen the self-closing force of the closer, it is necessary to increase the size of the spring and the counterweight, which creates a problem in terms of the installation space of the elevator
[0012] The closer always exerts a force on the door at the boarding place in the direction of closing the door, so if the self-closing force of the closer is strengthened, when the door at the boarding place is opened, the self-closing force must be overcome and the car door is usually larger. The driving force makes the door at the stairway move to the door opening direction, which will lead to the problem of large-scale driving mechanism

Embodiment 1

[0029] 1 to 4 show a first embodiment. These drawings are front views of the boarding place side viewed from the inside of the elevator passage of the elevator installed in the building.

[0030] A doorway 1 is formed on a wall surface of a boarding place, and a doorway frame 2 is provided on the wall surface so as to surround the doorway 1 . The doorway frame 2 has a pair of longitudinal beams 3a, 3b and a crossbeam 4 stretched between the upper parts of these longitudinal beams 3a, 3b, and the guide rail 5 is horizontally attached to the crossbeam 4. As shown in FIG.

[0031] 10 is the door at the stairway of the switch entrance and exit 1, the door at the stairway 10 has a suspension 11 on the upper part, and the suspension 11 is freely movably suspended on the above-mentioned guide rail 5, and the door 10 at the stairway passes along the guide rail 5 Move to open and close entrance 1.

[0032] A toggle spring mechanism 14 is provided on the beam 4 of the access frame 2 ....

Embodiment 2

[0052] 6 to 8 show the second embodiment. In this embodiment, the bracket 15 of the toggle spring mechanism 14 is freely rotatably mounted on the hanger 11 of the door 10 at the boarding place through a shaft 16. In addition, a spring member 22 is provided extending between a substantially middle portion of the bracket 15 and the beam 4 of the doorway frame 2 , and an engaging pin 25 engageable with the engaging groove 17 of the bracket 15 is attached to the beam 4 .

[0053] In the case of this embodiment, when the landing door 10 moves in the door-closing direction, as shown in FIG. Inclined stable state.

[0054] Then, when the landing door 10 moves in the door-closing direction together with the car door 27 and reaches a predetermined position, the engagement groove 17 of the bracket 15 provided on the landing door 10 engages with the engaging pin 25 of the beam 4 .

[0055] As the door 10 at the boarding place moves further towards the door closing direction, the engagi...

Abstract

A door device of an elevator, comprising a landing door (10) and a car door (27). When these doors are open, immediately after the car door (27) with a drive force is moved from a door closed position in a door opening direction, the car door (27) is engaged with the landing door (10) through an engagement mechanism (28), and these both doors are moved in a door opening direction. When the doors are closed, the car door (27) and the landing door (10) are integrally moved in a door closing direction in the engaged state with each other, their engagement is released immediately before they reach the door closed position, and the transmission of the drive force from the car door (27) to the landing door (10) is cut out. The door device also comprises a toggle spring mechanism (14) which, when the doors are closed, is engaged with the landing door (10) immediately before the car door (27) and the landing door (10) near the door closed position, releases the engagement of the car door (27) with the landing door (10), and elastically presses the landing door (10) in the door closing direction.

Description

technical field [0001] The present invention relates to an elevator door device, which is used to switch the entrance and exit of the car and the entrance and exit of the boarding place when the elevator car stops. Background technique [0002] There are entrances and exits for getting on and off the elevator car at the boarding place on each floor of the building. In addition, a doorway frame is provided to surround the doorway, and a sliding door-type landing door is provided on the doorway frame, and the doorway is opened and closed by the landing door. [0003] The landing door is usually locked, and when the car ascending and descending in the elevator passage stops and stops at the landing, it receives the driving force from the car door of the car to perform the switching action. [0004] The car door of the car is provided with an engaging mechanism for engaging with the landing door and transmitting the driving force from the car door to the landing door. When ope...
