The operability is good, and accurate operations can be performed instantly even in an emergency.

  Hereinafter, an embodiment of a portable security buzzer of the present invention will be described with reference to FIGS.

  1 to 3, reference numeral 1 denotes a portable security buzzer, which is provided with a sounding portion 3 incorporating a buzzer in the center of the front surface of a buzzer body 2 having a substantially oval shape in front view. On the back surface of the buzzer body 2, a battery lid 4 that closes a battery housing portion that houses and arranges a battery as a driving power source so as to be openable and closable is disposed. A pair of switches 5a and 5b are disposed on both sides of the buzzer body 2, and the buzzer is configured to operate as described later by simultaneously pressing the switches 5a and 5b. A reset switch 7 is provided in a recess 6 provided in the lower end surface of the buzzer body 2.

  In addition, a pair of universal joints 8a and 8b is disposed on the upper surface of the back surface of the buzzer body 2, and the upper end of the holder 10 is swingably attached to a hinge portion 9 including the universal joints 8a and 8b. . With this configuration, the holder 10 has a posture along the back surface of the buzzer body 2 as shown by a solid line in FIG. 1B, and an inclined posture separated from the back surface of the buzzer body 2 as shown by a virtual line. Can swing between the two.

  The holder 10 is configured by providing a pair of belt insertion openings 11a and 11b arranged in series vertically, and is carried around the belt insertion openings 11a and 11b by carrying a school bag, a shoulder bag or the like on the shoulder. The holder 10 is configured to be fixed to the shoulder belt 12 by inserting the shoulder belt 12 (see FIG. 5) of the portable bag into a zigzag shape.

  A recessed portion 13 is formed on the side surface of the upper end of the buzzer body 2, and a hanging pin 14 is provided in the recessed portion 13 so that one end of the hanging string 15 can be connected.

  Next, the configuration of the electric circuit will be described with reference to FIG. A buzzer circuit 17 using a piezoelectric element and its switch circuit 18 are connected in series to a battery 16 for power supply, and a latch circuit 19 is provided for outputting an on / off signal for turning the switch circuit 18 on or off. . In addition, a circuit 22 is provided in which a capacitor 20, a resistor 21, and a pair of switches 5a and 5b are connected in series and connected between both terminals of the battery 16 so that the capacitor 20 is on the high potential side. A potential signal between 21 is connected to the input terminal 19 a of the latch circuit 19. The latch circuit 19 outputs an off signal to the switch circuit 18 when a potential equal to or higher than the first predetermined value is input to the input terminal 19a, and when the input potential falls below the second predetermined value, the switch circuit thereafter. 18 is configured to output an ON signal, and the switch circuit 18, the latch circuit 19, and the circuit 22 constitute a switch mechanism 23. A reset switch 7 is connected in parallel with the capacitor 20.

  Thus, since the charging potential of the capacitor 20 is inputted to the input terminal 19a of the latch circuit 19 in normal times, the switch circuit 18 is in an off state and the buzzer circuit 17 is not activated. Further, in this state, even if either one of the pair of switches 5a and 5b is turned on or when both the switches 5a and 5b are pressed for a very short time such as 0.1 second or less, the capacitor 20 Since the charging potential decreases only with a time constant determined by the capacitor 20 and the resistor 21, the potential input to the input terminal 19a does not decrease so much, and the switch circuit 18 is in an off state and the buzzer circuit 17 is not activated.

  On the other hand, for example, when the pair of switches 5a and 5b are simultaneously pressed and turned on for a predetermined time of about 0.5 seconds or more, the charge of the capacitor 20 is discharged through the resistor 21 and the pair of switches 5a and 5b, and the input terminal 19a of the latch circuit 19 is discharged. The potential decreases, the switch circuit 18 is turned on by the latch circuit 19, the buzzer circuit 17 is activated, and this state is continued. In order to stop the operation of the buzzer circuit 17, the high potential of the battery 16 is applied to the input terminal 19 a of the latch circuit 19 by turning on the reset switch 7, and then the switch circuit 18 is turned off in the latch circuit 19. The operation of the buzzer circuit 17 is stopped.

  If necessary, as indicated by a virtual line, a receiving unit 24 for receiving an emergency signal emitted from another portable device such as an emergency transmitter or a mobile phone is provided, and the receiving unit 24 is based on the received signal. A signal that causes the latch circuit 19 to perform the same operation as when a potential equal to or lower than the predetermined value is input to the input terminal 19a may be output to the latch circuit 19.

  When the portable security buzzer 1 having the above-described configuration is used in a school bag for a child, the shoulder bag of the school bag or the like is placed with the holder 10 in an inclined posture away from the back surface of the buzzer body 2 as shown in FIG. The belt 12 is inserted into the plurality of belt insertion openings 11a and 11b of the holder 10 in a zigzag shape, the holder 10 is positioned at a desired position of the shoulder belt 12, and then the shoulder belt 12 is pulled as straight as possible. The portable security buzzer 1 is fixed without being easily moved. Thereafter, the buzzer body 2 is placed in a parallel posture with respect to the holder 10, and the portable security buzzer 1 is placed along the shoulder belt 12.

  In addition, even if the hinge 9 is broken and the buzzer body 2 is detached from the holder 10, it may be dropped unexpectedly or thrown away in a state where a buzzer is sounding and its function is impaired. In order to prevent this, the suspension pin 15 provided on the buzzer body 2 is coupled through one end portion of the suspension strap 15, and the suspension strap 15 is wound around the shoulder belt 12, and the hook portion 15a at the tip is attached. It is hung on the middle part of the hanging strap 15. Thus, the portable security buzzer 1 is attached to the shoulder belt 12 in the state shown in FIG.
