Description

[Detailed description of the invention]

This invention is applicable to convex movements such as construction work, etc.
, a safety helmet worn by workers to prevent falls.
-Related to safety belts. This invention was filed in Patent Application No. I 86260 in 1986.
What's behind the improved technology of the No. 1 octopus technique U + content from now on] - Safety belt metal fittings (attached to both ends of 1 robe (= J
+) The knock is equipped with a detection means (]1iu-) that detects when the target ring is inserted into the hook part of the hook body.
An electric wire is placed in the center of the ninth strand of the metal fitting, and power is relayed to both of the detection means via the electric wire, and a relay is connected between the wires of both of the detection means. Interposed with an alarm buzzer - made by C! If the worker is in a rope oil state, and the main hook and auxiliary hook are removed, the alarm bell will sound an alarm, alerting the worker and surrounding workers to ensure safe work. Prompt - something. Therefore, in this prior application, the alarm buzzer does not sound when either the main hook or the auxiliary knock hook is hung from a tree or hung on the hanging ring of a building or moving object. When I hang one i+Ii auxiliary knock side and finish the movement, when I fall down and release the auxiliary hook from the one-tree hanging state, the kidneys and) J buri "- will make a sound, but at that time there is no 11Fi ffl state. Shun 1, there was a risk of causing an accidental crash, so one stage of hook detection, which was taken at both ends of the metal fitting E10-B, was placed on the 11-1 Noil system strand. Since the structure relays the temperature through electric wires, there is a drawback that wearing it during electrical work can lead to dangers such as electric shock. The present invention has been made to solve the above-mentioned conventional drawbacks.
Regarding the use of safety belts, it is recommended to use the main hook when working as specified in ↑1. - is installed to prevent the main hook from being hooked, as a warning bell will sound when the main hook is hooked.

~It is connected to Tofunsister. Incidentally, the end faces of the photoreceptor 71 and the optical cover 18 are connected like the light emitter 1'1 shown in FIG. The alarm circuit 59 is similar to d3 as shown in FIG. Therefore, if the power switch 65 of the auxiliary knock 5 ( ) is turned on and the main hook 20 is not hooked to the object (C), the micro switch 391.a is turned on and the light emitting body 4'1 lights up. The end face of the optical fiber 7-pull 16 is illuminated, and this light is transmitted through the optical fiber cable 1-3 (the light is emitted from the end face to the light-receiving face 7' opposite the end face). 1. When this light is received (detected), it goes up to the photoreceptor 11 and current flows through the micro switch 6 due to photoelectric conversion.In this case, the auxiliary hook 50 is the target. 11) Mike is stopped by something 1] Suitsuji 60 is 0
1"l-, so the yq signal link 61 outputs 4f.
Since it is turned on, an alarm will sound. In addition, this alarm sound and the ``J'' (5 and 4) have different tones, and are set to sound intermittently.Next, the above J: Sea urchin R'l of this example was created ('l
Regarding Ill, 'J1 light, this pole-mounted safety belt 1 (the horizontal cable hook is fastened to the object IZ 11+G 11, t, the two alarms installed on the auxiliary hook 50'-6 -1 does not emit an alarm sound.It is the small strip A'1.That is, when the both end hooks 20 and 'a(1) are removed from the object, it emits an alarm sound.This will be explained for each state as follows: (The soil hook 20 and the auxiliary hook 50 are hooked onto the object.)
-A stage where you can eat rice. In this state, the microphone [I
Since the switch 39 is OFF, the warning buzzer 49 of the oscillator 40 does not emit a warning sound, and the light emitting body 41 is also activated, causing the optical fiber cable 18 to emit a 1 (1 copy) sound. At A3 on the auxiliary hook 50 side, the photoreceptor 71 installed opposite the optical fiber cable '18 has a high resistance, stopping the flow of current, and the microswitch 6o is also in the 0'' state, so an alarm is issued. The buzzer 61 does not emit an alarm sound. (U) When the auxiliary hook 50 is pressed 11) 1L to the target item without using the main knock 20. In this case, the microphone 1" switch 39 of the main knock 20 is O
Warning buzzer 49 of oscillator 40
Light up the sound. Also, the light emitting body 41 is stippled, and the light is guided to the photoreceptor 71 and illuminated by the light emitting element 18, and the resistance value of the photoreceptor 71 is reduced, causing a current to flow.
However, the auxiliary hook 5o is hung on the object S.1, and its microswitch 6° is turned off, so the alarm buzzer 61 does not emit an alarm. (c) Target the main hook 20. When hooking onto an object and not using the auxiliary hook 50. In this case, the micro switch 39 of the main hook 20 is set to OFF.
'F, the warning buzzer 47 does not issue the warning r1, and the light emitter 11-1 does not blink. Therefore, even if the microphone [l switch 6o of the auxiliary hook 50 is in the ON state, the photoreceptor 71 has a strong resistance and no current flows, so the alarm ``-6'1 outputs the alarm 7;1. (d) When the main hook 20J3 and the auxiliary hooks 1 are not hung on the object. In this case, the micro switch 39.60 of the main hook 20J3 and the auxiliary hook 50 is turned on. When the warning bridge 47 of the main knock 20 is turned off, the light emitting element 41 lights up and illuminates the light receiving element 71 (this 1ζ
The photoreceptor 71 conducts current, and if the auxiliary hook 50 is in the ON state, the alarm bridge 61 emits an H alarm sound. Shilkobi (a)
Conditions (b) and (c) are safe work conditions, and (
The condition d) is a warning that there is no trunk at all, and a gamma alarm. Also, (Ron's state is not using the main hook, so in this case, the principle of issuing a warning brie'?1 knock?3 and using the main knock?)
At the same time, this is a warning that the auxiliary knock should not be hooked or unlatched.Therefore, if the C1 hook is in use, it should be used to warn both the worker himself and other workers, as well as surrounding workers. It is important to issue warnings and alerts to prevent crashes from occurring.In addition, both knocks are connected to optical fiber back-pulses. 1. Since it is connected by a []-b, it does not cause damage due to electric shock etc.) 1. It does not bend and can be used as a pole-mounted safety belt. By installing a warning circuit independently on the C alarm circuit side of the auxiliary knock in the same way as the main hook B, it is possible to completely eliminate the non-wireless condition. Gulp.
