Abstract

(57) [Summary] [Structure] The triangular guard plate 7 is a triangular guard plate body 7a,
It is composed of a triangular guard plate cylinder 7b and is attached to the ceiling 1. The heat sensitive sensor 7c is attached to the triangular guard plate cylinder 7b at one or more places. The thermal sensor 7c may be attached to the ceiling 1. The buzzer 8 and the power supply device are attached to the suspension 6. The buzzer 8 and the power supply device 9 may be housed in a separate box and attached to the ceiling 1. [Effect] When a part of the human body is outside the handrail, the thermal sensor attached to the triangular guard plate detects the approach of the human body and sounds the buzzer to warn the passengers.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a device for preventing a trapped accident in a building ceiling of an escalator or at an intersecting portion of two intersecting escalators.

[0002]

[Prior Art]

 In the conventional device, as described in Japanese Utility Model Laid-Open No. 63-18474, an alarm is issued by expanding and contracting the swing of the triangular guard plate.

[0003]

[Problems to be solved by the device]

 The above-mentioned prior art does not consider the point of preventing an accident caused by being caught without contact, and there is a problem that if a warning is issued after the contact, the passenger's body is caught at the intersection.

An object of the present invention is to prevent an accident due to a crossing portion being caught.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a heat sensor on the triangular guard plate, and when the human body approaches the triangular guard plate, the triangular guard plate detects the contact without contact before it warns. Call attention to passengers or stop the escalator to prevent accidents.

[0006]

[Action]

 When the human body approaches the triangular guard plate, the amount of infrared energy changes. The amount of change is detected and the detection device is operated. As a result, the alarm buzzer sounds and the passengers are alerted. Also, when approaching a certain distance, stop the escalator.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a detailed view of a triangular guard plate portion of an escalator equipped with a safety device according to an embodiment of the present invention.

The triangular guard plate 7 is composed of a triangular guard plate main body 7 a and a triangular guard plate cylinder 7 b as shown in the figure, and is attached to the ceiling 1. Attach the thermal sensor 7c to the triangular guard plate cylinder 7b at one or more places. The thermal sensor 7c may be attached to the ceiling 1. The buzzer 8 and the power supply device are attached to the suspension 6. The buzzer 8 and the power supply device 9 may be housed in a separate box and attached to the ceiling 1.

FIG. 2 is a side view of the entire escalator.

The balustrade 4 is attached to the escalator body 2. Attach the handrail 5 to the balustrade 4 and enter the escalator body. Passengers take step 5 and go up or down. The triangular guard plate 7 is attached to the intersection of the escalator body 2 and the ceiling 1 as shown in the figure.

[0012]

[Effect of the device]

 According to the present embodiment, when the passenger rides on step 3 and goes from the lower side to the upper side, when a part of the human body is outside the handrail 5, the human body is approached by the heat-sensitive sensor attached to the triangular guard plate. When it detects it, it sounds a buzzer to call attention to passengers. It also has the effect of stopping the escalator when approaching within a certain distance to prevent an accident caused by being caught.
