Abstract

PURPOSE:To allow an emergency rescue door to be fully opened by operating a movable handrail provided in a cage from either the inside or outside of the cage at the emergency rescue time so as to displace this movable handrail, positioned inward the emergency rescue door, from the movable door inward position. CONSTITUTION:One end of a movable handrail 10b provided inward a rescue door 4 is supported by a sliding pin 33, and this sliding pin 33 is energized inward and can be operated from both inside and outside. The other end of the movable handrail 10b is connected to the end part of an adjacent fixed handrail 10a. The movable handrail 10b, from which the sliding pin 33 is pulled out, is rotated around a hinge 11 by its self-weight and held vertically in a position off the inner part of the rescue door.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the installation of an in-car handrail when an emergency rescue exit is provided on the side plate of an elevator car.

2. Description of the Related Art FIG. 5 is a front view showing two conventional elevator cars that are adjacent to each other disclosed in Japanese Utility Model Application Publication No. 2-26704, FIG. 6 is a sectional view taken along the line A-A in FIG. 5, and FIG. FIG. In the figure, 1 is a car compartment, 2 is a handrail forming a link mechanism, and 3 is a treadle. Normally, the handrail 2 and treadle 3 are folded inside the car so that they do not interfere with elevator operation.

Next, the operation will be explained. In order to transfer passengers to the adjacent elevator when the elevator makes an emergency stop on a non-stop floor, open the emergency rescue door 4, which forms part of the side plate of the car, as shown by the two-dot chain line in Figure 7, and close the handrail. 2. The treadle 3 is pulled out to allow passengers in the car that has made an emergency stop to transfer to an adjacent car. However, Figure 7
When the handrails 10a to 10d are provided in the car as shown in the figure, even if an attempt is made to open the emergency rescue door 4, the handrail 10c hits the handrail 10c and the door does not open sufficiently, which has the drawback of hindering the rescue work for passengers.

[0004] Therefore, an improvement plan has been proposed in which the handrail 10b corresponding to the rescue door 4 is made freely rotatable around a support shaft at one end to avoid contact between the handrails and increase the opening angle of the emergency rescue door. There is.

[0005]

[Problem to be Solved by the Invention] However, even with this improved proposal, since the handrail is attached directly to the emergency rescue door, the rotated handrail gets in the way and makes it difficult for the emergency rescue door to open completely. There was a drawback that there was not enough rescue space for passengers, which hindered the rescue work for passengers and was extremely dangerous.

[0006] This invention was made to solve the above-mentioned problems, and even if a handrail is provided inside the car as in the past, it can be operated from either inside or outside the car in the event of an emergency rescue. By holding the movable handrail located inside the emergency rescue door in a vertical position at a position away from the inside of the emergency rescue door, the emergency rescue door can be fully opened and a space for passenger rescue can be secured. The purpose is to obtain equipment.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the elevator car handrail mounting device according to the present invention has the following features:
One end of the movable handrail provided inside the emergency rescue door is supported by a sliding pin that penetrates the inside and outside of the emergency rescue door, and this sliding pin is biased inward by a spring and can be operated from the inside and outside. The other end of the movable handrail is connected via a hinge to the end of the adjacent fixed handrail beyond the rescue door and inside the car side plate, and the sliding pin is moved backwards against the spring. The movable handrail from which the movable pin has been pulled out rotates around the hinge due to its own weight, and is held in a vertical position at a position away from the inside of the emergency rescue door.

[0008]

[Function] In the elevator car handrail mounting device of the present invention, in an emergency, when the sliding pin is slid outward against the spring from either the inside or outside of the emergency rescue door, the movable handrail will be able to pull out the sliding pin. , rotates around the hinge due to its own weight, and is held in a vertical position at a position outside the inside of the emergency rescue door.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a cross-sectional plan view of the car, Fig. 2 is an enlarged detailed view of the corner of the car room in Fig. 1, Fig. 3 is a plan view when the handrail is rotated and the emergency rescue door 4 is fully opened, and Fig. 4 is the same as Fig. 1. It is a sectional view taken along the line B-B. In the figure, reference numeral 10b denotes a movable handrail provided inside the car of the rescue door 4, one end of which is supported by a sliding pin 33 inserted into the slide hole 41 that penetrates the inside and outside of the emergency rescue door 4. The sliding pin 33 is urged inward by the coil spring 32 interposed between the bracket 31 and the flange 34 of the sliding pin 33, and is pushed against the coil spring 32 by the inner knob 42 or the outer knob 43. It can be slid by hand. The other end of the movable handrail 10b is connected to the adjacent fixed handrail 10 on the inside of the car side plate 14 beyond the emergency rescue door 4.
It is connected to the end of a through a hinge 11. Therefore, as shown in FIG. 4, when the sliding pin 33 is pulled out, the movable handrail 10b rotates around the hinge 11 due to its own weight, and moves to a position away from the inside of the emergency rescue door 4, as shown by the dashed line. is configured to be held in a vertical position.

The emergency rescue door 4 can rotate about the shaft 6 as shown in FIG. . The sliding mechanism of the sliding pin 35 is the same as that of the sliding pin 33, so a description thereof will be omitted. Inside the car front plate 5, one end of a movable handrail 10e is supported by a pin 35, and the other end is supported by a hinge 12 at the end of an adjacent fixed handrail 10c.
When the sliding pin 35 is pulled out, the movable handrail 10e rotates around the hinge 12 due to its own weight and is maintained in a vertical state.

With the above structure, in an emergency, you can pinch either the inner knob 42 or the outer knob 43 of the emergency rescue door, pull out the sliding pin 33 against the coil spring, and remove the movable handrail 10b. rotates automatically as shown in Figure 4. At this time, the movable handrail 10b is located away from the emergency rescue door 4 and does not interfere with the rotation of the emergency rescue door 4. Similarly, the movable handrail 10e also rotates around the hinge 12 by pulling out the sliding pin 35 and is held in a hanging state, so that it does not get in the way when the emergency rescue door 4 is fully opened as shown in FIG. Since the sliding pin 35 and the sliding pin 33 are shifted in position, they are in a parallel state when fully opened and do not cause any obstruction. Since the emergency rescue door 4 can be fully opened in this way, passengers can quickly transfer to an adjacent car. Since the sliding pin can be operated from the outside, this work can be done without the cooperation of the general passengers inside the car.

[Effects of the Invention] As described above, according to the present invention, when a movable handrail is provided inside the car of the emergency rescue door, one end of the movable handrail is supported by a sliding pin that penetrates the inside and outside of the emergency rescue door. This sliding pin is urged inward by a spring so that it can be operated from the inside and outside, and the other end of the movable handrail is hinged to the end of the adjacent fixed handrail inside the car side plate beyond the emergency rescue door. By the retreating movement of the sliding pin against the spring, the movable handrail rotates around the hinge due to its own weight and can be held in a position away from the inside of the emergency door. It can be operated from either direction and can be fully opened with the movable handrail removed, making it possible to carry out emergency rescue work safely and without any hindrance.
