Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention, when a nurse call switch is pressed,
It relates to a nurse call device that can be easily confirmed on the spot and that has a return switch that can be released on the spot by an operation different from the nurse call switch operation if the nurse call switch is pressed by mistake. is there.

[Conventional technology]

As we live in an aging society and increase the number of people living alone, nurse call equipment is often installed in facilities for the elderly, etc. in preparation for emergencies such as illness and unexpected accidents. The push button for pushing is configured so that the nurse call switch is turned on regardless of the posture, that is, the push button is pushed from any position of up, down, left, and right.

[Problems to be Solved by the Invention]

When the nurse call switch of the related art is pressed, it is not possible to confirm whether the switch is turned on or not when the nurse call switch is pressed, which causes anxiety to the operator. Further, since the nurse call switch is turned on regardless of which position of the push button is pressed, if the body or hand is inadvertently touched by the switch, the switch is turned on to notify the monitoring room.

The present invention has been made to solve the above problems, and enables the operator to confirm that a call has been made. Even if the nurse call switch is pressed by mistake, the operator can press the nurse call switch. The purpose is to obtain a nurse call device that can be restored by a different operation from.

[Means for Solving the Problems]

A nurse call device according to the present invention includes a switch for a nurse call, a buzzer that operates by turning on the switch for the nurse call and continues to ring, and a recovery switch that operates by pulling up or rotating to restore the ringing of the buzzer. And are integrated.

[Action]

According to the present invention, when the nurse call switch is pressed to turn it on, the caller is notified that the call is being made, and the buzzer sounds and the caller can confirm the call. Further, by pulling up or turning the return switch, the buzzer stops ringing and returns to the normal state.

2A and 2B show the first switch unit 3 of FIG.
The details of the configuration of FIG. In this figure, the first
The same reference numerals as those in the drawings indicate the same parts, 31 is a substrate constituting the first switch section 3, 32 is a push button of the switch SW ₁ for the nurse call, which is pressed from any direction of up, down, left, right. Switch for nurse call
₁ can be operated. Reference numeral 33 is a pull-up button of the switch SW ₂ for returning that cancels the nurse call, and push button 3 of the switch SW ₁ for nurse call
In order to prevent erroneous operation, the pulling-up method is more troublesome than pushing without performing the pushing operation, and is provided at a position retracted from the push button 32 in the recess 34 formed in the substrate 31. There is. The configuration of the second switch unit 4 is also the same as that of the first switch unit 3, and therefore the illustration thereof is omitted.

Next, the operation of FIG. 1 will be described with reference to FIG.

First, in a normal state, when the door is unlocked and the locking / unlocking detection switch 5 is off, the changeover switch ry is in the illustrated state when the relay RY is inactive, and the power supply of the monitoring room 1 is The current from V _{cc is} from the terminal T ₁ of the information sorter 2 to the restoration switch SW ₂ → the restoration switch SW ₄ → the contact point r _{2 of the} changeover switch ry → the resistor R ₁
Through the resistor R ₀ of the monitoring room 1 and the monitoring circuit 11. That is, 12V of the power supply _Vcc is divided by the resistors R ₁ and R ₀ , and a voltage of 8V appears at both ends of the resistor R ₀ .

In the normal state, when the door is locked and the locking / unlocking detection switch 5 is turned on, the contact point r ₂ of the changeover switch ry passes through the resistor R ₂ → the locking / unlocking detection switch 5 and the monitoring room 1 It flows through the resistor R ₀ and the monitoring circuit 11. In this case, it flows to the resistor R _1, since the resistor R ₁ is a high-resistance than the resistor R _2, hardly flows through the resistor R _1, flows in most resistor R _2. Therefore, the voltage across the resistor R ₀ is, for example, 10V.
Therefore, the monitoring circuit 11 measures the voltage across the resistor R ₀ , and when the value is low at 8 V, it means that the swing lock detection switch 5 is off, and it can be determined that the door lock is unlocked. When the voltage across the resistor R ₀ is high at 10 V, it means that the lock / unlock detection switch 5 is on, and it can be determined that the door lock is installed.

Next, when the resident in the room wants to call the manager by calling the monitoring room 1 due to some accident, for example, when trying to call from the toilet, the switch for nurse call of the first switch unit 3 Press the push button 32 of SW ₁ ,
Since the nurse call switch SW ₁ is turned on, the current flows from the terminal T _{1 to the} reset switch SW _{2 to} SW _{4 to the} nurse call switch SW _{1 to the} diode D _{1 to the} relay R.
It is grounded in the monitoring room 1 via Y → terminal T ₂ . For this reason, the relay RY operates, so that the changeover switch ry is changed over from the contact point r ₂ to the contact point r ₁ . Therefore, the current flowing through the resistors R ₁ and R ₂ is cut off, and the resistor R ₀
The voltage across both ends of the line is zero V. A display that keeps the relay RY self-held by the contact r ₁ and is switched to the contact r ₁ even when the nurse call switch SW ₁ is automatically returned and turned off, and is turned on at the same time as the relay RY is operated. The lighting state of the lamp 6 is also continued. In addition, since no current flows through each of the resistors R ₁ and R ₂ , the voltage across the resistor R ₀ becomes 0. Therefore, the monitoring circuit 11 confirms that the resident has turned on the switch SW ₁ for nurse call. Can be determined.
At the same time, since the nurse call switch SW ₁ is turned on, a current flows through the resistors R ₃ and R ₄ and the thyristor SCR ₁ operates, so that the buzzer BZ ₁ sounds, but the push button 32 is pressed. Thyristor SCR even if the switch SW ₁ for nurse call is turned off after self-recovering
_{Since the} operation is held at ₁ , the buzzer BZ ₁ continues to ring. Even if the nurse call switch SW ₁ is turned on, the buzzer BZ ₂ of the bathroom second switch section 4 is prevented from flowing a current to the resistors R ₅ and R ₆ by the diode D ₂ and the thyristor SCR is blocked. ₂ does not start, so buzzer B
Z ₂ does not ring.

In addition, push button 3 of switch SW ₁ for nurse call
When the body touches 2 and turns on, switch S for return
By pulling up the pull-up button 33 of W ₂ , the switch SW ₂ for restoration is turned off, and the current stops flowing in the buzzer BZ ₁ , so that the ringing of the buzzer BZ ₁ stops and the current stops flowing in the relay RY. The self-holding of the relay RY is released, the contact r ₁ of the changeover switch ry is switched to the contact r ₂ , and the indicator lamp 6 is also turned off.

Although the above description of the operation has been given for the first switch section 3, the same applies to the second switch section 4.

Furthermore, when the buzzer BZ ₁ is driven by pressing the switch SW ₁ for nurse call, the manager confirms by operating the switch SW ₀ for return of the monitoring room 1 to stop the ringing of the buzzer BZ _1. You can give the expectation and stability that you will drive.

The return switches SW ₂ and SW ₄ are not limited to push-up type switches, and similar effects can be obtained by using a switch that operates by rotation.

Although the switch section 3 has five terminals in the embodiment shown in FIG. 1, an example having two terminals is shown in FIG. The same parts as those in FIG. 1 are designated by the same reference numerals. In this embodiment, the current of the thyristor SCR ₁ is allowed to flow through the relay RY as it is. The second switch unit 4 is omitted in FIG.

〔The invention's effect〕

INDUSTRIAL APPLICABILITY As described above, the present invention operates by turning on the nurse call switch, the nurse call switch, and the buzzer that continues to ring, and the pull-up or rotation that restores the ringing of the buzzer. Since a recovery switch that operates is provided integrally, the buzzer sounds at the place where the nurse call switch is pressed, so it is possible to confirm on the spot that the nurse call was made, and therefore the reliability of the nurse call device. It is possible to significantly improve the sex.
Also, even if a part of the body touches the nurse call switch and the buzzer sounds by accidentally pressing it, the buzzer stops operating by operating the return switch,
It is possible to return to a normal state. Since the recovery switch is operated by pulling up or rotating instead of pressing like a nurse call switch, it is extremely rare that the operator mistakenly recovers the switch.
