That is, when viewed from the back surface 20 side of the protective plate 10, the handle 11 and the button 51 are arranged in a straight line in the vertical direction Z. The button 51 may be provided within a range reachable by the fingers of the hand holding the handle 11. The button 51 may be provided within a range of 5 cm or less from the gripping portion 32 of the handle 11.
[0032] In one embodiment, the button holding portion 100 is configured such that the lower end portion on the rear side in the front-rear direction X protrudes downward more than the lower end portion on the front side. The upper end portion 31 of the handle 11 is configured such that the upper end portion on the front side in the front-rear direction X protrudes upward more than the upper end portion on the rear side. The button holding portion 100 and the upper end portion 31 of the handle 11 have a shape that fits together. That is, the contact surface (boundary surface) B between the button holding portion 100 and the upper end portion 31 of the handle 11 has an inclined surface or a curved surface that gradually descends as it approaches the rear end from the front end. When viewed from the back surface 20 side of the protective plate 10, the button 51 of the button holding portion 100 may be arranged so as to overlap a part of the upper end portion 31 of the handle 11.
[0033] Button 51, battery A, and speaker 52 are configured to be electrically connectable by wiring, a circuit board, a switching circuit, etc. When button 51 is pressed and turned on, battery A and speaker 52 are electrically connected, and speaker 52 emits sound. When the pressing of button 51 is released and turned off, battery A and speaker 52 are electrically disconnected, and the sound emission stops. The sound emitted from speaker 52 may have a volume of 100 dB or more and less than 130 dB. The sound emitted from speaker 52 may have a frequency in the high-frequency band of 3000 Hz or more and 4000 or less. The type of sound is not particularly limited. Button 51 may move forward when an external force is applied and return to its original position when the external force is removed.
[0034] When using the protective shield 1 configured as described above, the user holds the left and right handles 11 on the back surface 20 of the protective plate 10 with both hands, for example. Then, by pressing button 51 with the finger (thumb) of the held hand, a loud sound is emitted from speaker 52 toward the front of the protective plate 10. By releasing the finger from button 51, the sound emission of speaker 52 is stopped.
[0035] According to this embodiment, the protective shield 1 includes a protective plate 10, a handle 11 disposed on the back surface 20 of the protective plate 10, and a sound-emitting device 12 disposed on the protective plate 10 that emits sound by pressing button 51. Button 51 is disposed in the vicinity of handle 11 and is configured to be pressed by the user while holding handle 11. Thereby, the user can quickly and easily emit a warning sound while firmly holding the protective shield 1 with both hands.
[0036] Since button 51 is disposed in the vicinity of the upper end portion 31 of handle 11, the user can suitably press button 51 while holding handle 11.
[0037] Since the speaker 52 is exposed on the front surface 21 of the protective plate 10 and is arranged to face forward of the protective plate 10, it can emit sound toward the person using the protective shield 1. Thereby, it is possible to intimidate the person and prompt the person to leave. In addition, it is possible to prevent the sound from directly reaching the user of the protective shield 1.
[0038] Since the speaker 52 is arranged in the through-hole 55 of the protective plate 10, the attachment structure of the speaker 52 can be simplified. In addition, it is possible to suppress damage to the speaker 52.
[0039] The speaker 52 is arranged above the upper end portion 31 of the handle 11 in the protective plate 10. Thereby, it is possible to suppress the speaker 52 from blocking the user's field of view.
[0040] The protective shield 1 includes a suppression portion 85 that suppresses the sound of the speaker 52 from diverging rearward of the protective plate 10. Thereby, it is possible to protect the user's ears.
[0041] Since the sound emitting device 12 has the power supply of the battery A, the portability of the protective shield 1 is improved and the protective shield 1 can be used anywhere. In addition, by replacing the battery A or charging the battery A, the protective shield 1 can be continuously used.
[0042] Since the protective plate 10 is transparent, the speaker 52 can emit sound toward the person while the user secures a field of view through the protective plate 10.
[0043] The protective shield 1 is not limited to the configuration described in the above embodiment. The number, arrangement, and structure of the handle 11, the speaker 52, and the button 51 are not limited to those of the above embodiment.
