Description

[Detailed Description of the Invention] The present invention relates to a car side rescue opening provided in an elevator car.

Conventionally, in elevators for high-rise buildings, when one car stops due to a failure between floors, another adjacent car is stopped in a position parallel to the failed car, and an emergency exit is installed on the side of the car room. There are known devices that allow passengers to be moved and rescued through the

In this type of vehicle, a footboard is installed to easily guide passengers to the outside of the rescue door on the side of the car compartment, and this footboard is normally folded and stored in a frame provided on the side of the car compartment, so that it can be used in case of an emergency. I try to pull it out of the frame and install it.

By the way, if you close the rescue door and operate the elevator with the treadle in the pulled-out position, there is a risk of damaging the various equipment installed in the hoistway around the boarding area, which may cause the elevator to malfunction again. A switch is provided to confirm that the treadle is retracted, and the vehicle can only be operated when the treadle is retracted.

However, with this type of elevator, the switch may operate unexpectedly due to vibrations during elevator operation, cutting off the control circuit and causing the elevator to stop, causing a so-called canning accident.
It tends to lack reliability.

Conventional switch drive means have had problems, such as the need to increase the accuracy of parts and to put a lot of effort into assembly in order to avoid such a situation.

The present invention was devised to solve such problems, and the object thereof is to provide an inexpensive and highly reliable car side rescue exit.

Hereinafter, one embodiment of the present invention will be briefly described with reference to the drawings.

A rescue door 3 is provided at a rescue exit 2 on the side of the car 1 so that it can be opened and closed inward.

Further, a tread plate 4 is attached to two elongated frames 5 provided parallel to the outer surface of the car 1.

The footboard 4 has one end rotatably attached to the frame 5 via a rotation pin 9, and the other end attached to one end of two footboard supports 7.

A stud pin 10 provided at the other end of the tread support 7 is slidably inserted and supported in a groove 11 provided in the two frames 5.

Note that the upper end of the groove 11 is curved in a direction away from the car 1.

These footboards 4 and footboard supports 7 constitute a set of sliding link mechanisms.

Then, the other end of the tread support 7 is bent so as to protrude in the direction of the rescue door 3, and the inside of the locking part formed by this bent other end is in contact with the folded part 13 of the rescue door 3 in the closed position. I try to be an engaged child.

Further, another groove 15 is provided above the groove 11 on which the tread support 7 slides.
A stopper 8 for stopping and holding the treadle support 7 is provided to be slidable up and down via this groove.

This stopper 8 has a groove 16 with an open lower end that engages with the stud pin 10 of the tread support 7, and when the stud pin 10 of the tread support 7 engages with this groove 16 while pushing up the stopper 8. When the pin 10 is unlocked and the stopper 8 is lowered by its own weight, it can be locked.

Next, the effect will be explained.

In case of emergency, open the rescue door 3 and raise the stopper 8.

Then, the dead weight of the tread support 7 and the tread plate 4 causes the implant pin 10 provided at one end of the tread support 7 to slide down the groove 11 of the frame 5 and stop at the lowest end of the groove 11.

At this time, the footboard 4 rotates under its own weight, and the footboard 4 is automatically installed as shown in FIG.

Next, when trying to close the rescue door 3 in this state, the protruding part 12 of the tread support 7 comes into contact with the folded part 13 of the rescue door 3,
The rescue door 3 cannot be closed in its normal position.

Therefore, when closing the rescue door 3, when the tread plate 4 is rotated and stored in the frame 1 □, the stud pin 10 of the tread support 7 is inserted into the groove 11.
It slides inside and is guided into the curved groove at the top end while pushing up the stopper 8.

Then, when the implant pin 10 comes directly under the groove 16 provided in the stopper 8, the stopper 8 falls, pinching the implant pin 10, and fixing the footboard device.

Furthermore, since the locking portion 12 consisting of the protruding portion of the footboard support 7 faces the notch 14 position of the rescue door 3, this locking portion 12
The rescue door folding part 13 is no longer in contact with the rescue door folding part 13, and the rescue door can be stored in the normal storage position.

According to the device of this embodiment, the footboard 4 is automatically installed by lifting the stopper 8 that locks the footboard support.

Conversely, by rotating and storing the footboard 4 in the frame 5, the stopper 8 automatically locks and fixes the footboard support 7.

Furthermore, the rescue door 3 requires that the treadle device be stored within the frame 5.
Since the locking portion 12 of the treadle support cannot be closed, operating the elevator with the treadle 4 installed can be reliably avoided.

As explained above, according to the present invention, the installation and storage of the rescue exit on the side of the car compartment can be easily carried out, and furthermore, since the interlock using the electrical switch is replaced with a mechanical interlock, malfunction of the switch etc. is eliminated, and the reliability is increased. It can provide a highly efficient escape route.
