【Example】

 Embodiments of a portable crime prevention device according to the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a perspective view when the present invention is configured as a portable security badge 10, and FIG. 2 is a perspective view showing a state where the security badge 10 is separated into a drive unit 11 and a cartridge type movable unit 12. Is.

As shown in FIG. 3, the drive unit 11 has a motor 14 built in the center of the case body 13 and a pair of batteries 15, 16 built in the outer periphery thereof. Both batteries 15 and 16 are held in the case body 13 by leaf springs 17 and 18 which also function as contact pieces, and are operated by a switch 19 arranged at the tip of these leaf springs 17 and 18. The switch 19 is fixed to the case body 13 and has a structure in which a switch button 20 is projected to the outside. When the switch button 20 is pressed, the tip ends of the leaf springs 17 and 18 on both sides come into contact with each other to conduct electricity, and the power is turned on to rotate the motor 14. As shown in FIG. 4, the case main body 13 has a bottom plate 21 that can be removed by screws 22. When replacing the batteries 15 and 16, the bottom plate 21 can be easily removed. Further, as shown in FIGS. 2 and 4, a circular recess 23 is formed in the central portion of the upper surface of the case body 13 for mounting the movable part 12, and the recess 23 is formed. A locking protrusion 24 for fixing the movable portion 12 is formed on the entire inner peripheral wall of the above. The drive shaft 25 of the motor 14 projects on the upper surface of the recess 23 to form an axial spline.

On the other hand, as shown in FIG. 4, the movable part 12 has a disk-shaped bottom body 27 corresponding to the recess 23 and a curved lid body 28 for covering the upper part thereof, and has a space inside. A storage case 30 having a portion 29 is configured. As shown in FIGS. 2 and 4, the lid 28 is provided with a pair of air outlets 31 and 32 at opposite side positions. Further, in the space 29 of the storage case 30, a large number of small pieces of paper 33 are randomly stored, and the rotary blades 34 formed of plastic are also stored. As shown in FIGS. 4 and 5, the rotary blade 34 has six blades 36 radially provided around a support shaft 35, and the upper and lower ends of the support shaft 35 are provided in the storage case 30. The bottom body 27 and the lid body 28 are rotatably supported by being fitted in shaft holes formed in the central portions of the bottom body 27 and the lid body 28, respectively. An axial groove 37 is formed on the inner peripheral surface of the support shaft 35 so as to fit with the spline of the drive shaft 25 of the motor 14. In addition, a pair of blades 36a, 36a located at opposite positions among the six blades 36 of the rotary vane 34 is a circle that closes the pair of outlets 31, 32 provided in the lid 28 from the inside. A flat portion 38 having a shape is formed. Then, by utilizing the elastic force of the blades 36a, 36a, as shown in FIG. 4, the flat portion 38 is normally pressed against the blowout ports 31, 32 from below to close the blowout ports 31, 32. As a result, it is possible to prevent the paper pieces 33 accommodated in the space 29 from spilling out from the outlets 31 and 32.

Next, the operation of the security badge 10 having the above structure will be described. First, as shown in FIG. 3, the movable portion 12 is fitted into the recess 23 on the upper surface of the driving portion 11, and the spindle 35 of the rotary blade 34 is fitted onto the driving shaft 25 of the motor 14. When the switch button 20 is pressed in this state, the left and right leaf springs 17 and 18 are connected to rotate the motor 14, and the rotational force is transmitted to the rotary vanes 34 via the drive shaft 25. At this time, the rotary blades 34 resist the rotational force because the flat portions 38 formed on the pair of blades 36a and 36b are engaged with the peripheral edges of the outlets 31 and 32. Since the engaging force is small due to the elastic action of plastic, when the rotational force from the motor 14 is received, the flat portion 38 and the surroundings of the outlets 31 and 32 are disengaged and rotated, and the inside of the storage case 30 is rotated. It will turn around vigorously. Therefore, a large number of paper pieces 33 housed in the storage case 30 are also swirled around the space 29 together with the rotary blades 34, and are blown off by the wind into confetti from the outlets 31 and 32. It When the switch button 20 is pressed again after the end, the rotation of the motor 14 can be stopped. Further, the used movable part 12 can be removed from the recess 23 of the drive part 11 and the new movable part 12 can be fitted to the drive part 11 in the same manner as described above to prepare for the next step.

Therefore, for example, as shown in FIG. 6, the crime prevention badge 10 is attached to the chest of the child 39, and when a danger occurs, simply push the switch button 20 to face the opponent who intends to do harm. Since the confetti 40 can be released from the chest, the child 39 can easily handle the confetti 40, which helps prevent danger. Further, since the confetti 40 is vigorously and widely discharged from the outlets 31 and 32, it is possible to attach the confetti 40 to clothes or the like over a wide range with respect to a partner who is a little away. In this way, the fact that the confetti 40 is released from the chest of the child 39 is an act of surprise to a person who intends to do harm, and thus it has the function of deterring this type of crime, and it is also small. Since it is the paper piece 33, it cannot be easily wiped off by hand, so that it is possible to escape the adhering confetti while it is being wiped off. In addition, it is difficult to wipe off confetti that has adhered, which makes it easier to rely on it to later discover the perpetrator.

When an aluminum stay or the like is used instead of the above-mentioned paper piece 33, it becomes more difficult to remove it when it adheres, and since the aluminum stay is reflected and becomes more conspicuous, the crime prevention effect is further enhanced. . Moreover, if the piece of paper 33 is coated with a fluorescent paint, it will be obvious that it adheres to the piece of paper 33 to shine even at night.

In the above-mentioned embodiment, since the badge can be easily attached to the chest of the child 39, the child 39 can be attached in the same manner as a name tag, so that there is no feeling of discomfort to carry and it is also possible to carry it. You will never forget.

Although the present invention has been described as the crime prevention badge 10 in the above-mentioned embodiment, it is not necessarily a bag, and any bag that can be carried may be used. Also, the case where the movable part 12 is of the cardridge type has been described, but it is also possible to refill paper pieces or aluminum pieces by refilling, and even in this case, handling is extremely easy compared to paints and the like. Is. Further, although the case where the motor 14 using the batteries 15 and 16 as a power source is used for the drive unit 11 has been described, the rotary vane 34 can also be operated by, for example, a mainspring, and in this case, the entire badge is It can be made lightweight and compact.

[0015]
