DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIGS. 1 and 2, a ventilator comprises a panel 10 configured to extend over the wearer of a protective garment. Several strings 11 and 12 are provided in the peripheral portion of the panel 10, and the panel 10 can be attached to the wearer's body by fastening them to each other.

Alternatively, for example, Velcro (VELCR)
A plurality of connecting means 16 made of a freely connectable locking material such as those sold by O) are fixed to the front surface of the panel 10. A plurality of coupling means 92 are secured to the inner surface of the protective garment 90 (FIG. 3) and cooperate with the coupling means 16 of the panel 10 to attach the panel 10 to the protective garment 90 without the use of strings 11 and 12. It is said that Although it is preferable to use a matable locking material as described above, it will be clear that snap-fit coupling means are also suitable for this purpose.

As yet another method, the connecting means 13 is connected to the string 1.
By fixing the free ends of the cords 1 and 12, the cords 11 and 1
The two can be fastened to each other.

The panel 10 comprises a first impermeable material.
The layer 20 and the second layer 30 having the same shape as the first layer 20 are provided. The peripheral portions of the two layers 20 and 30 are fixed to each other by high-frequency heating or the like, so that the panel 10 forms an air bag having a hollow interior. The opening 21 is provided in the first layer 20. The pipe 14 is the first layer 20
And is communicated with the opening 21. A plurality of ribs 15 are provided at the free end of the pipe 14 to allow the panel 10
The hose is configured to be able to receive a hose through which fresh air supplied to the hollow inside passes.

Preferably, the panel 1 is provided with a plurality of "+"-shaped coupling means 17 formed by, for example, high frequency heating.
By providing the two layers 20 and 30 with each other, the central portion of the panel 10 is prevented from expanding greatly so that the influence of the expansion of the panel 10 does not affect the work of the wearer. It Also, providing a plurality of holes 31 in the second layer 30 improves the circulation of air around the wearer's body.

The portion 32 of the second layer 30 is not perforated to prevent fresh air from flowing directly into contact with the wearer's body. Alternatively, attaching baffle 33 to both layers 20, 30 prevents fresh air from flowing directly into contact with the wearer's body. A part of the peripheral portion of the baffle plate 33 is fixed to the first layer 20 when the baffle plate 33 is attached to the first layer 20, whereby an air passage is provided between the baffle plate 33 and the first layer 20. It can be formed so that fresh air flows from the air passages into the hollow interior of panel 10 but does not flow directly into contact with the wearer's body.

Referring now to FIG. 4, in another embodiment of the present invention, the panel 10 is configured to extend across the wearer's chest. The inside is hollow 2
One extension 40 is provided at the bottom of the panel 10 and its hollow interior communicates with that of the panel 10,
Fresh air flows to the wearer's legs. A plurality of cords 18 are provided for wrapping around the wearer's legs to hold the extension 40 in place.

Referring to FIG. 5, a ventilator according to yet another embodiment of the present invention has a flap 50 formed on one side of the panel 10 formed to extend over the wearer's back. It is similar to that shown in FIG. The hollow interior of flap 50 communicates with that of panel 10 to allow fresh air to flow to the wearer's back.

Therefore, the ventilator of the present invention can supply fresh air to the body of a worker wearing protective clothing, thereby greatly improving the circulation of air around the body, and Can bring a feeling of comfort.

[0014]

As described above, according to the ventilator of the present invention, fresh air is supplied to workers wearing protective clothing,
Further comfort can be brought about.
