Abstract

PURPOSE:To facilitate passenger rescue by forming a recess portion, in a wall of an elevator cage, which is recessed toward the elevating/descending passage side, shield the recess portion with a cover, and furnishing the ceiling portion of the cage with a rescue opening which includes the upper edge of the recess portion. CONSTITUTION:When a rescuer on the top of a cage 3 slides a cover plate 13 of a rescue opening 12 in the lateral direction, an engaging piece 13a disengages the upper part 14a of a cover 14. This allows the cover 14 to be opened downward, exposing the inside of a recess portion 11. Then, as the lower end of a ladder 16 is pulled toward passengers and pulled downward, the upper end of the ladder 16 is guided by a guide groove 17 so that the ladder 16 is set up inside the cage 3. This makes it possible to rescue the passenger through the rescue opening 12, using the ladder 16 and landing steps 15. In this case, since the cover plate 13 slid in the lateral direction, it can be opened without being disturbed by upper beam equipment or the like. Furthermore, since the area of the rescue opening 12 expands by the depth of the recess 11, passenger rescue becomes easier.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a rescue exit device installed in the ceiling of an elevator car.

[Prior art] Figure 6 is, for example, published by Japan Institute of Invention and Innovation, branch number 84-00.
5005 is a vertical cross-sectional view of the main part of the car room showing the rescue exit device of the elevator shown in FIG.

In the figure, (1) the vertical pillars that make up the frame, and (2) the vertical pillars (
1) an upper beam that connects the upper parts of the cages, (3) a car compartment that has been carefully installed, and (4) a rescue opening that opens into the ceiling of the cage compartment (3). ) has a rescue opening cover (5) pivotally attached to the opening. (6) is a lifting device such as a lifting wheel attached to the top beam (2), and (7) is a mounting arm fixed to the vertical column (1), on which the door closing device (8) is installed. ing. (9) is a car door installed at the entrance/exit of the car room (3) and driven by the door closing W (8).

Conventional elevator rescue exit devices are constructed as described above, and when a car stops between floors due to an elevator malfunction, a rescuer can access the rescue exit lid (5) from outside the car room (3). ) is opened, and the passengers inside the car (3) are rescued through the rescue door (4). Furthermore, the above-mentioned document indicates that a ladder is installed in the center of the car (3) for grasping elderly people and physically disabled people, and that this ladder is also used for rescuing passengers when the elevator breaks down. has been done.

[Problems to be Solved by the Invention] In the conventional elevator rescue exit device as described above, the rescue exit (4) is provided in the ceiling of the car compartment (3).
The rescue opening lid (5) was blocked by the climbing equipment (6), etc.
The problem is that there is not enough space to open the car, and there is also a lack of space to rescue passengers from the rescue door (4), which is especially noticeable in small cages (3), making it difficult for passengers to escape. There is a point.

Also, the reason why there is a ladder in the center of the car room (3) is because
There are problems in that the space inside the car (3) is reduced and the interior is damaged.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an elevator rescue exit device that has a wide rescue exit area and facilitates the rescue of passengers.

In addition to the above objects, another object of the present invention is to provide an elevator rescue exit device that facilitates rescue operations and prevents damage to the interior of the car interior.

[Means for Solving the Problems] An elevator rescue exit device according to the present invention includes forming a concave part in the wall of the car room that recedes toward the hoistway side, covering this with a cover, and installing the above-mentioned four parts on the ceiling of the car room. It is equipped with an evacuation opening that includes the upper edge of the

Further, an elevator rescue exit device according to another invention of the present invention is one in which, in addition to the above-mentioned device, a ladder is housed in the recess.

[Function] In this invention, a receding recess is formed in the wall of the cabin, and a rescue exit including the upper edges of the four parts mentioned above is provided in the ceiling, so the rescue exit area is expanded by the depth of the recess. .

Further, in another aspect of the present invention, since the ladder is housed in the recess, the ladder can be used by opening the cover on the front surface of the recess, and the ladder is not exposed inside the car during normal times.

E Embodiment FIGS. 1 to 5 are diagrams showing an embodiment of this invention.
The figure is a vertical side view of the main part of the car compartment, Figures 2 and 3 are diagrams showing the car compartment in normal conditions, Figure 2 is a vertical side view (including a partially enlarged view), and Figure 3 is a perspective view. 4 and 5 are diagrams showing the car room in case of an emergency, FIG. 4 is a vertical side view, and FIG. 5 is a perspective view, and the same parts as those of the conventional device are shown.

In the figure, (11) is a recess formed when the front wall of the car room (1) retreats toward the hoistway side, and the rescue opening (12) is the recess (11).
) is open including the upper edge thereof, and is closed by a rescue opening cover (13) that slides horizontally, and an engaging piece (13a) bent in an L-shape is formed on the lower surface of the rescue opening cover (13). ing. (14) is a cover that opens and closes the front of the recess (11);
The upper part (14a) is the engagement piece (1) of the rescue port cover (13).
3a). (15) is a ramp fixed in parallel in the recess (11), (16) is a ladder stored in the recess (11), and its upper end is connected to the guide groove (17) provided in the recess (11). is engaged in.

In the elevator rescue exit device configured as described above, normally, as shown in FIGS. 2 and 3, the cover (14) of the recess (11) is located upward;
14a) is engaged with the engagement piece (13a) of the rescue port cover (13). Now the rescue opening (12) and the recess (11)
are each blocked, and the ladder (16) etc. are blocked off in the car room (3).
The inside of the car is not exposed, and space is secured inside the car compartment (3).
And it won't damage the interior.

Next, in an emergency that requires rescuing a passenger, the rescuer slides the rescue port cover (work 3) horizontally from above the car compartment (3), and the engagement piece (13a) and cover (14) are separated. Upper part (14
a) is disengaged. The cover (14) can now be opened downward, exposing the inside of the recess (11).

Here, by taking the lower end of the ladder (16) and pulling it toward you and then pulling it downward, the upper end will be guided by the guide groove (17), so that the ladder (16) will be (Step 6) is set in the car compartment (3). with this,
Passengers can be rescued from the rescue opening (12) using the ladder (16) and gangway (15). At this time, since the rescue port cover (13) is sliding in the horizontal direction,
It can be opened without disturbing the climbing equipment (6), etc., and the area of the rescue opening (12) is expanded by the depth of the recess (11), making it easier to rescue passengers.

[Effects of the Invention] As explained above, in this invention, a receding recess is formed in the wall of the car room, this is covered with a cover, and a rescue exit including the upper end of the recess is provided in the ceiling. The area is expanded by the depth of the recess, which has the effect of making it easier to rescue passengers.

In another aspect of the present invention, the ladder is housed in the recess, so that when the front cover of the recess is opened, the ladder can be pulled out, making rescue work easier, and the ladder is not exposed inside the car during normal times. This has the effect of ensuring sufficient space within the car and not damaging the interior.
