Claims

[Claims for Utility Model Registration] By causing the detector 2 to transmit a detection wave in response to the opening/closing movement of the shutter 1, an object search area of a required width is formed in the front and rear areas centered on the opening/closing path of the shutter 1. On the other hand, only if there is a person or obstacle within the object search area when the shutter 1 is opened/closed, the interlock device 3 is activated to cause the sound generator 4 to emit a warning sound, and at the same time, the shutter 1 is opened/closed. A safety device for an electric shutter characterized by stopping the movement. The detector 2 forming the object search area is a light emitter/receiver 21, 22 consisting of an infrared emitter 21 and an infrared receiver 22, and when the light reception of the light receiver 22 is cut off, an interlock device 3 activates a sound generator. 4
2. A safety device for an electric shutter according to claim 1, wherein a warning voice is emitted when the shutter is opened and a shutter opening/closing motor 5 is stopped at the same time. The detector 2 forming the object search area is an ultrasonic detector 21, 22 consisting of an ultrasonic oscillator 21 and an ultrasonic microphone 22, and when the ultrasonic detector 2 searches for an object within the search area, an interface is activated. A safety device for an electric shutter according to claim 1, wherein the lock device 3 causes the sound generator 4 to emit a sound and simultaneously stops the opening/closing motor of the shutter. The detector 2 forming the object search area is a radio wave detector, and when the radio wave detector 2 searches for an object within the search area, the interlock device 3 causes the sound generator 4 to emit a sound, and at the same time the shutter is activated. The opening/closing motor 5 is stopped.
Electric shutter safety device. The detector 2 that forms the object search area is a heat ray switch that is sensitive to the radiant heat of the object, and when this heat ray switch operates in response to the body temperature of a person or animal, the sound generator 4 makes a sound and A safety device for an electric shutter according to claim 1, wherein the opening/closing motor 5 of the shutter is stopped. A safety device for an electric shutter according to claim 1, wherein the sound generator 4 is a loudspeaker using a magnetic tape cassette recorder. 2. The sound generator according to claim 1, wherein the sound generator 4 is a magnetic drum cassette type electronic sound generator.
Electric shutter safety device.
