Description

[Detailed Description of the Invention] The present invention relates to a hood for protecting the head and respiratory organs, which is used while supplying clean air into the hood through an air supply pipe.

<Prior art> Fig. 6 was filed before the present application (Utility patent application filed in 1983-
49190) is a side view of a simple type hood. In the figure,
21 is a hood body, 22 is an eyepiece, 23 is an eave attached to the hood body 21 to keep the eyepiece 22 at a certain distance from the face, and 24 is an air pipe attachment port.

In this hood, air is supplied into the hood from the side below the eyes of the hood wearer, so the clean air supplied into the hood constantly flows in a swirling manner over the face, causing the eyes of the wearer to It has the disadvantage of causing discomfort such as dryness.

<Purpose of the invention> The object is to obtain a respiratory protection hood that does not have the above-mentioned drawbacks.

<Configuration of the invention> The characteristics of the invention are that, in the hood of Utility Application No. 59-49190, it is configured so that the purified air supplied inside the hood can be supplied to the upper space of the eaves, and the front edge of the eaves is The point is that ventilation holes are arranged in a row along the

<Example> FIG. 1 is a front view of a hood according to the present invention, and FIG. 2 is an enlarged side view of the same main part. In the figure, 1 is a hood body made of a suitable flexible fabric, 2 is an eyepiece made of a flexible transparent thin plate attached by sewing or the like to the viewing window of the hood body 1, and 3 is the periphery of the eyepiece. Reference numeral 4 denotes an eave attached to the inner surface of the upper edge of the eyepiece 2 in order to hold the eyepiece 2 at a position away from the face. [See Figure 3] The eaves 4 has a front edge mounting piece 5 connected to its front edge and side edge mounting pieces 6 and 7 connected to its left and right side edges, and a stopper that passes through the eyepiece 2 and the hood body 1. It is attached to the hood body by being polymerized and fixed to the inner surface of the eyepiece 2 with a pin. Further, a large number of ventilation holes 8 are arranged in a row near the front edge of the eaves 4, and a cut-and-raised piece 9 is provided at a position facing the air supply pipe connector. Note that the vent holes 8 located on the left and right sides of the front edge attachment piece 5 may be cutouts that open at the edge of the eaves 4.

FIG. 4 is an enlarged sectional view taken along the line - in FIG. 2, and shows the mounting structure of the air pipe connector 10. The air supply pipe connector 10 consists of an air supply pipe connection port 11 and an air supply guide pipe 12. The air supply pipe connection port 11 is fixed to the hood body by an air supply guide pipe 12 that passes through the eyepiece 2 and the hood body 1 and engages with the inner peripheral edge of the air supply pipe connection port 11. Air supply guide pipe 1
A groove-shaped air supply guide wall 13 is provided on the inside of the eaves 2, and a cut-and-raised piece 14 of the eaves 4 is attached to a pin 15 on the outer surface.
It is fixed by. (See Figures 3 and 5) With the above configuration, when the air pipe is connected to the air pipe connection port 11 and purified air is supplied, the purified air enters the upper space of the eaves 4, and then the air enters the upper space of the eaves 4. The air flows downward through a series of ventilation holes 8 along the leading edge of the air.

<Effect of the invention> In the hood of the invention, the clean air supplied into the hood does not come into contact with the eyes, so
Unlike the hood according to the earlier application of the present application, the hood does not cause discomfort such as dry eyes to the wearer.
