Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an escalator, and particularly to a safety device for an escalator suitable for an escalator with many passengers such as children.

[Conventional technology]

At approximately triangular intersections that are close to the building ceiling above the escalator railings or the bottom surface of another escalator that intersects, triangular guard plates as specified in the escalator safety measures standard No. 25 issued by the Ministry of Construction will be installed. ing. This triangle guard plate is
If a passenger on an ascending escalator has their arms or the like sticking out of the moving handrail, the system is designed to warn passengers of danger by touching their arms or the like. Incidentally, related devices of this type include, for example, Japanese Utility Model Application No. 51-66992.

[Problem that the invention attempts to solve]

However, in the conventional device described above, the switch for sounding the alarm (buzzer, etc.) is activated by the impact force applied to the triangular guard plate. It's difficult to make it ring. This is because in order to generate the impact force that activates the switch, it is necessary to instantaneously apply a strong force to the triangular guard plate, and the body of the passenger resting on the running step is forced to press against the triangular guard plate. This is because the impact force sufficient to activate the switch will not be generated if it hits the switch.

In addition, in the case where the triangular guard plate is fixedly supported on a stationary part such as the ceiling of a building or the bottom of an escalator, when a passenger bumps into it, there is a risk that it will cause a large impact force on the passenger and cause him or her to fall. be.

The purpose of the present invention is to ensure that an alarm is sounded when the triangular guard plate swings, and to prevent passengers from receiving a large shock even in the event of a collision.

[Means for solving problems]

The above object is provided in an escalator, and is swingably suspended from the building ceiling or the lower surface of the escalator at a substantially triangular intersection adjacent to the lower surface of another escalator that intersects with the building ceiling above the railing of the escalator. In a safety device for an escalator having a substantially triangular triangular guard plate, the triangular guard plate includes a switch, an alarm that issues an alarm when the switch is activated, and one end of which is attached to the ceiling of the building or the lower surface of the escalator. and an actuator whose other end is connected to the switch and which operates the switch by a relative movement with the building ceiling or the lower surface of the escalator when the triangular guard plate swings. This is achieved by

[Effect]

As mentioned above, in the event that a passenger bumps into the triangular guard plate, the triangular guard plate swings, thereby pulling or loosening the actuating body and turning the switch on. Therefore, if the triangular guard plate swings to a certain extent, the alarm will be activated, and when a passenger bumps into it, the triangular guard plate will be pushed by the passenger and move, so the triangular guard plate will be fixed to the passenger. A large impact force is not applied as in the case where the

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings. Fig. 1 is an explanatory diagram of an escalator safety device which is an embodiment of the present invention, Fig. 2 is a side view of an escalator equipped with a safety device which is an embodiment of the present invention, and Fig. 3 is an explanatory diagram of an escalator safety device which is an embodiment of the present invention. FIG. 4 is a front view of the alarm device housed inside the cylindrical body provided on one side of the triangular guard plate, and FIG. 4 is a side view of the alarm device of FIG. 3.

In Figures 1 and 2, 1 is the ceiling, 2 is the escalator body, and the escalator body 2 includes a plurality of endless steps 3 and balustrades 4 erected on the left and right sides of these steps 3. A movable handrail 5, etc., which runs on the parapet 4 in synchronization with the step 3, is provided. Balustrade 4 Upper ceiling 1
A substantially triangular guard plate 7 is suspended from a hanging body 8 attached to a hook 6 fixed to the ceiling 1 at a substantially triangular intersection adjacent to the ceiling 1 .
This triangular guard plate 7 is made up of a plate 7a and a cylindrical body 7b, and this cylindrical body 7b is used to prevent passengers on an ascending escalator from protruding their arms or the like beyond the moving handrail 5. It is hung vertically so that it is in contact with the area where it is placed. On the other hand, plate 7a
has a shape that covers a triangular portion consisting of the parapet 4, the ceiling 1, and the cylindrical body 7b, and the plate 7a and the cylindrical body 7
b is integrated. Inside the cylindrical body 7b, there is a switch 11, an alarm device such as a buzzer 12 that issues an alarm when the switch 11 is closed, one end of which is connected to the hook 6, the other end of which is connected to the switch 11, and a triangular portion guard plate 7. switch 11 due to the rocking of
an operating body 10 that operates the alarm, a power supply device 13 equipped with a battery, and a stop switch 14 that stops the alarm.
and a plate (reference numeral 15 to be described later) to which these items are attached.

Next, in FIGS. 3 and 4, reference numeral 15 denotes a plate housed in the cylindrical body 7b, which is pulled onto the upper end of the triangular guard plate 7 by a hook 15a provided at the upper end of the back surface of the plate 15. The switch 11 and the buzzer 1 are hung on the surface of the plate 15.
2, a power supply device 13 and a stop switch 14 are respectively attached, and these are connected by a wiring 17. The actuating body 10 has a metal fitting 10c that engages with the hook 6 at one end and a wire 10b that connects to the switch 11 at the other end.
A spring 10a is provided between the wire 10b and the wire 10b. 16a and 16b are pulleys that guide the wire 10b of the operating body 10. Note that the metal fitting 10c of the actuating body 10 is attached to a hook 6 fixed to the ceiling 1.
When engaged, the entire actuating body 10 is in an expanded state due to the spring 10a.

In this embodiment configured in this way, the triangular guard plate 7 is damaged due to a mischief by an escalator passenger.
When the spring 10 swings to the right in FIG.
The actuating body 10, which had been extended by a, is relaxed, the switch 11 is turned on, and the buzzer 12 issues an alarm.
Therefore, the passenger who was playing the prank will be surprised by the alarm and stop the prank immediately.

In this embodiment, the triangular guard plate 7 at the substantially triangular intersection adjacent to the ceiling 1 above the balustrade 4 has been described; Exactly the same effect can be expected from a triangular guard plate (not shown) provided at a substantially triangular intersection adjacent to the triangular intersection.

In addition, in this embodiment, a buzzer 12 is used as an alarm.
However, instead of the buzzer 12, an audio device may be provided to issue a warning not to do mischief.

According to this embodiment, when the triangular guard plate swings due to a mischief by an escalator passenger, an alarm is issued, and the mischievous passenger immediately stops the mischief. Therefore, damage to the triangular portion guard plate due to mischief can be prevented.

In addition, if a part of the body of a passenger on an ascending escalator protrudes beyond the moving handrail and hits the triangular guard plate, an alarm will be issued, allowing the passenger to withdraw immediately, further improving safety. can.

[Effect of idea]

As described above, according to the present invention, in the event that a passenger bumps into the triangular guard plate, the triangular guard plate swings, which causes the actuating body to be pulled or loosened and the switch to be activated. Since the triangular guard plate is configured to enter the vehicle, the alarm will be activated if the triangular guard plate swings to a certain extent, and when a passenger bumps into the triangular guard plate, the triangular guard plate will be pushed by the passenger and move. This has the effect that a large impact force is not applied as in the case where the triangular portion guard plate is fixed.
