The present invention relates to a security window safety detection device of an elevator, and more particularly to a security window safety detection device of the elevator to control the operation of the elevator by detecting the damage of the security window installed on the elevator car door and each landing side door.

Currently, a security window is installed on the door side of an elevator so that the periphery of the platform can be seen on the door side of the elevator in order to prevent crime in an elevator installed in a multi-family residential building such as an apartment or an officetel. As such a security window is usually used because the tempered glass is likely to be broken, accordingly, the body of the occupant, especially the child may be exposed to the operation of the elevator when the security window is damaged, there is a high possibility of a safety accident.

Therefore, in view of the above circumstances, the present invention detects the damage of the entire security window installed on the elevator and the landing door, and detects the safety of the safety of the elevator to stop the operation of the elevator if at least one security window is broken. The object is to provide a device.

According to the present invention to achieve the above object, in the elevator having a security window corresponding to the security window formed on the landing side door, the door lock switch contact for detecting the closed state of the elevator door and the installed on the car door side The door closing switch of the landing side indicating the closing state of each landing side door is connected to the security window detection element for detecting the state of the security window, and the door closing confirmation switching element indicating the operation state of the elevator when the security window detection element is normal. Security window safety detection device of an elevator constructed by connecting a security window detection device that detects a contact point and a state of a security window installed on each door of a landing door to a landing-side door closing confirmation switching device indicating an operating state of the elevator when the landing door is normal. Is provided.

Preferably, the security window detection element is composed of an ultrasonic sensor, the ultrasonic sensor is composed of an ultrasonic light emitting element and a light receiving element which are installed to have a predetermined inclination angle with respect to the security window.

According to such a security screen safety device of the elevator according to the present invention, when the security window installed on the elevator car door side or the security window installed on each landing side door is damaged, the car door confirmation switching device or the landing door side closing confirmation switching device is inoperative The state of the elevator is controlled by the state.

Hereinafter, the present invention will be described in detail with reference to the configuration of FIG. 1.

In FIG. 1, c denotes a door closure switch contact that is maintained in a connected state when the door of the elevator car is completely closed and s denotes a security window detection device for detecting whether a security window installed on the card door side is damaged. , RY1 is driven when the card door closing switch contact (c) and the security window detection element (s) is connected to provide a control signal (not shown) for the elevator to control the operation of the elevator indicating a door state of the door. A cardor closing confirmation switching device is shown.

H1-Hn is a switch contact for checking whether the landing door of each floor is closed, S1-Sn represents a security window sensing device for detecting whether the security window installed in the landing door of each floor is damaged, and RY2 is each floor. And a landing side door closing confirmation switching element for providing a control means with a signal indicating the operating state of the elevator based on the state of the landing side door.

Here, the security window detection element (s; S1-Sn) may be composed of an ultrasonic sensor and a limit switch, the configuration example of the ultrasonic sensor is shown in Figure 2 (a) and (b) When the door-side security window detection device is representatively described, an ultrasonic light emitting device Sa for emitting ultrasonic waves to an opposite surface of the security window 12 installed in the elevator car door 10 and an ultrasonic light receiving irradiation Sb for receiving the ultrasonic waves are shown. If the security window 12 is installed and normal, the ultrasonic wave a emitted from the ultrasonic light emitting element Sp is reflected through the surface of the security window l2 and is received by the ultrasonic light receiving element Sr to detect the security window detecting element S. Can be configured to form a switch state, and the limit number position can be configured by, for example, patterning a wire switch pattern on the security window.

In such a configuration, the soundproof window installed in the elevator car door is broken so that the soundproof window detecting element is disconnected, i.e., an ultrasonic sound a transmitted from the ultrasonic light emitting element Sp illustrated in FIG. 2 to the light receiving element Sr. When the door is blocked by the breakage of the security window, the door closing confirmation switching element (RYl) is not operated, the elevator car can be controlled in a non-operational state.

For example, when any one of the security windows installed on the landing side is damaged, the security window detecting elements S1, S2, ..., Sn become non-connected, and thus the landing-side door closing confirmation switching element RY2 is deactivated. In this state, the driving of the elevator car is also controlled to be impossible.

therefore. According to the security screen of the elevator security device according to the present invention, by detecting the damage of the security window installed on the door and the landing door of the car door, if the damage of the security window is detected by preventing the elevator operation by preventing the safety accident caused by damage to the security window Can be.
