Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an escalator safety device, and particularly to a safety device at a substantially triangular intersection between an escalator being operated upward and the ceiling of a building, or two intersecting escalators. Regarding.

[Conventional technology]

Escalator and building ceiling or intersect 2
At the triangular intersections between the escalators, triangular guard plates are to be installed as specified in the Ministry of Construction's Residential Guide No. 25 Escalator Safety Measures Standard. This triangular guard plate is designed to warn passengers of danger by touching the triangular guard plate when the escalator is being operated upward and passengers are being carried with their arms sticking out of the moving handrail. There is. Note that related devices of this type include, for example, Japanese Utility Model Application Publication No. 51-66992.

[Problem that the invention attempts to solve]

The triangular guard plate is swingably suspended by a suspension body, and when a passenger pushes or hits the triangular guard plate, the triangular guard plate swings, causing the adjacent escalator to There were problems such as damage caused by hitting the parapet.

An object of the present invention is to provide a device that effectively prevents tampering with the triangular guard plate.

[Means for solving problems]

The above purpose is to provide a cylindrical body on the front edge of the triangular part guard plate, and to operate the triangular part guard plate when a passenger comes into contact with the triangular part guard plate and swings the triangular part guard plate. This can be achieved by providing an alarm device that issues an alarm.

[Effect]

When a passenger swings the triangular guard plate, a sensing section installed inside the cylindrical body at the front edge of the triangular guard plate activates and issues an alarm, thereby immediately stopping any tampering with the triangular guard plate. can.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, 1 is the ceiling, 2 is the escalator main body, and this main body 2 is provided with a balustrade 4 equipped with a step 3 that runs endlessly, a handrail 5 that runs in synchronization with this step 3, etc. . Further, from the ceiling 1, a substantially triangular guard plate 7 is provided which is suspended by a suspension body 6 so as to be located at a substantially triangular intersection formed by the ceiling 1 and the escalator 2. The triangular guard plate 7 is composed of a main body 7a and a cylindrical body 7b made of plastic. This cylinder 7b includes a cover 7c that covers the upper hole of the cylinder, and a hole 7 that emits an alarm sound.
d is provided inside this cylinder 7b,
When a passenger swings the triangular guard plate, a suspended body contact 8 that swings, a buzzer 9 that issues an alarm, a power supply device 10 that issues an alarm, and a contact 1 that detects the swing.
An alarm device consisting of: 1 is provided.

Now, when a passenger accidentally swings the triangular guard plate, the suspension contact 9 provided inside the leading edge cylinder 7b swings and contacts the contact 11 to form a closed circuit, causing the buzzer 9 to sound an alarm. emits. By this,
The passengers who were playing the prank were surprised by the alarm and immediately stopped the prank.

In this embodiment, a suspended body contact is used as the sensing section, but a liquid contact such as mercury may be provided and a closed circuit may be formed by the swinging of this liquid.

Further, although a buzzer is provided as a warning, instead of the buzzer, an audio device may be activated to issue a warning to avoid mischief.

[Effect of idea]

According to the present invention, when a passenger hits the triangular guard plate, the rocking of the triangular guard plate causes an alarm to be issued, so the passenger who was playing the prank immediately stops the prank. Therefore, damage to the triangular guard plate due to this mischief can also be prevented. It also activates if a non-mischievous passenger is leaning over and collides with the passenger; in this case,
You can withdraw immediately.
