Description

This disclosure relates to an elevator car door mechanism. In conventional elevator door systems, bolts are fixed to the door hanger. These bolts protrude from the door hanger below the door rail. Furthermore, when an external force is applied to the door panel, the bolts strike the lower part of the door rail, suppressing the tilt of the elevator door around the point of contact between the hanger roller and the door rail (see, for example, Patent Document 1). International Publication No. 2018/025328 This is a schematic diagram showing an elevator according to Embodiment 1.Figure 1 is a front view of the main part of the landing door device as seen from the hoistway side.Figure 1 is a front view of the car door mechanism as seen from the landing side.Figure 3 is a front view showing the fully open state of the cage door mechanism.This is a front view showing an enlarged view of the main part of Figure 3.This is a front view showing the bolt-shaped member in Figure 5 in its standby position.Figure 6 is a front view showing the state in which the bolt-shaped member is in the process of returning to the deformation-suppressing position.Figure 5 is a side view of the regulating member and the bolt-shaped member as seen along arrow VIII.This is a front view of the elevator car door device according to Embodiment 2, as seen from the landing side.Figure 9 is a front view showing the fully open state of the cage door mechanism.This is a front view of the elevator car door device according to Embodiment 3, as seen from the landing side.This is a front view of the elevator car door device according to Embodiment 4, as seen from the landing side. The embodiments will be described below with reference to the drawings. Embodiment 1. Figure 1 is a schematic diagram showing an elevator according to Embodiment 1. In the figure, a machine room 2 is provided above the hoistway 1. The machine room 2 houses a hoisting machine 3, a deflector 4, and an elevator control device 5. The hoisting machine 3 includes a drive sheave 6, a hoisting machine motor (not shown), and a hoisting machine brake (not shown). The hoisting machine motor rotates the drive sheave 6. The hoisting machine brake maintains the drive sheave 6 in a stationary position. The hoisting machine brake also slows the rotation of the drive sheave 6. A suspension system 7 is wrapped around the drive sheave 6 and the deflector wheel 4. The suspension system 7 is made up of multiple ropes or multiple belts. A cage 8 is connected to the first end of the suspension system 7. A counterweight 9 is connected to the second end of the suspension system 7. The elevator car 8 and counterweight 9 are suspended by the suspension body 7 and move up and down within the hoistway 1 by rotating the drive sheave 6. The elevator control device 5 controls the movement of the elevator car 8 by controlling the hoisting machine 3. Within the elevator shaft 1, there is a pair of car guide rails (not shown) and a pair of counterweight guide rails (not shown). The pair of car guide rails guide the movement of the elevator car 8. The pair of counterweight guide rails guide the movement of the counterweight 9. The elevator car 8 has a car frame 10 and a car compartment 11. A suspension system 7 is connected to the car frame 10. The car compartment 11 is supported by the car frame 10. A car door device 12 is provided on the front of the car compartment 11. A door controller 13 is provided on the elevator car 8. The door controller 13 controls the opening and closing operation of the elevator car door device 12. Each of the landings on multiple floors is equipped with a landing door device 14. Each landing door device 14 opens and closes in conjunction with the car door device 12 when the elevator car 8 lands. Figure 2 is a front view of the main components of the landing door device 14 shown in Figure 1, as seen from the hoistway 1 side. Each landing door device 14 includes a landing door frame 15, a first landing door body 16, a second landing door body 17, a landing door interlocking mechanism 18, and an interlock device 19. The landing door frame 15 is fixed to the upper part of the landing entrance. The landing door frame 15 is provided with a landing door rail 15a.
