Description

[Detailed description of the invention] This invention relates to a new emergency call switch that allows you to appropriately report an emergency situation by simply operating your foot, without distracting others when an emergency situation occurs. It is.

BACKGROUND ART Conventionally, banks, credit unions, etc. that handle money have been equipped with emergency notification switches that activate alarm devices near each bank employee in order to prepare for the occurrence of an emergency in order to deal with intrusion by robbers.

However, because conventional emergency call switches of this type can be easily operated with hands or feet, they can malfunction due to careless movement by the worker who presses the button during normal operations, or objects falling onto the switch. This was something that was easy to happen and led to confusion in the judgment of the security personnel.

The fact that security personnel are at the mercy of such frequent malfunctions also reduces their security awareness, which may lead to the possibility that warnings will be of no use when an emergency situation occurs.

On the other hand, a hand-operated emergency call switch has the disadvantage that it cannot fully function as an emergency call switch because it can be easily noticed by a burglar's gestures or movements when a burglar breaks in.

The present invention has been improved in view of these conventional drawbacks, and provides an emergency call switch that can be easily operated with the tip of the foot and does not malfunction.

The present invention will be explained in detail below with reference to embodiments shown in the drawings.

In FIGS. 1 and 2, 1 is a housing that is open except for a part of the upper part of the front surface so that the tip of the foot can be inserted;
Reference numeral 2 indicates a push plate that can be pushed up with the tip of the toe, and reference numeral 3 indicates a conventionally commonly used microswitch.

One end of the push plate 2 is rotatably provided on the inner wall of the housing 1 with a butterfly plate 4 or the like.

The micro switch 3 has a movable piece 5 and the push plate 2.
It is fixed to the inner wall of the casing 1 at a position where the two are almost in contact with each other.

The key 6 is provided on one side plate γ of the housing 1, and is configured to be locked when the push plate 2 is operated.

A small hole 9 is bored in the leftover front plate 8.

This is used to check the operating state of the push plate 2, and the push plate 2 is pushed up by a suitable paint applied to a part of the front plate of the push plate 2 or paper 10 attached to the push plate 2. By looking inside the small hole 10 when the
This is to check the color of the paint or paper inside.

This is especially convenient for checking the operating status when multiple devices are placed on the floor.

FIG. 3 schematically shows an embodiment of a key means for locking the push plate 2 in the pushed-up state.

In FIG. 3, 11 is a cam member, 12 is a spring, 13 is an L-shaped fitting attached to the key 6, and 14 is a connecting member that elastically connects the cam member 11 and the push plate 2.

Further, the cam member 11 is connected by a spring 12 to a support member 15 fixed to the front plate 8 of the housing 1 .

FIGS. 4a and 4b are a plan view and a side view showing the details of the vicinity of the key 6, respectively.
3 is shown installed.

In the normal state in which the push plate 2 is not pushed up with the above-described configuration, the cam member 11 contacts the side of the parallel portion 131 of the L-shaped fitting 13 attached to the key 6, as shown in FIG. It is positioned on the push plate 2 via a connecting member 14.

At this time, the spring 12 is compressed.

Next, when the push plate 2 is pushed up in an emergency etc., the cam member 1
1 is pushed up against the force of the spring 12 while being pressed by the side of the parallel part 1310 of the L-shaped fitting 13, and the cam member 11
The bottom surface portion 111 of the L-shaped fitting 13 is caught on the parallel portion 131 of the L-shaped fitting 13 and is locked in the pushed-up state.

When unlocking the push plate 20 locked in this way, a security guard or the like uses a special key to hold the key 6 in the third position.
By turning the lock in the direction of arrow C in the figure to unlock it, the bottom part 111 of the cam member 11 is released and the cam member 11 and push plate 2 fall down due to the force of the spring 12 and the weight of the cam member 11 itself. to return to normal state.

Note that the key means for locking the push plate 2 is as follows:
Various types can be used in addition to those described above.

In this way, the emergency call switch according to the present invention is placed near the feet of a worker who is working at a desk or counter, and when an emergency situation occurs, the worker can enter the housing 1 of the emergency call switch. By inserting the tip of your foot into the bar and lifting your toe slightly, you push up the push plate and turn on the switch, activating the alarm device.

For this reason, compared to conventional button-type switches that are pressed with your foot, there is no risk of malfunctions caused by accidentally touching your foot or dropping an object, making it extremely convenient as an emergency call switch. It's something new.

Furthermore, by providing the emergency call switch with a key means as shown in the embodiment, once the push plate is pushed up and the alarm switch is turned on, the key is simultaneously locked and the key is opened. Unless it is locked, the push plate will not return to the bottom and the alarm bell will not ring, so once the alarm bell starts ringing, a security guard must come to the scene and unlock the door for the door to recover.

Therefore, an intruder cannot cancel the activation of the alarm device, and the security guard is not allowed to be negligent, ensuring a perfect security system.
