Description

The invention of the present application is a structure for adjusting the size of a face-exposing opening that exposes the wearer's face in a hood that covers the wearer's head in clothing, and in particular, the size of the face-exposing opening is adjusted in the longitudinal direction. and laterally adjustable structures.

The structure for adjusting the size of the opening for exposing the face in the hood according to the invention of the present application can be widely used in various types of clothing with a hood, such as coats and parkas. The face exposing opening in the hood of disposable medical protective clothing that is worn in medical institutions to prevent contamination of one's own body or clothes and to prevent oneself from contamination of the surroundings. A case where a portion size adjusting structure is employed will be described as an example.

The hood in the medical disposable protective clothing described above protects the wearer's head from contamination by foreign substances such as dust, and also protects the wearer's head from being contaminated by hair and skin fragments falling from the wearer's head. It has the role of preventing contamination.

Here, the hood (Aa) in the medical disposable protective clothing (A) is adapted to the size or shape of the wearer's (B) head, as shown in FIG. The face should be adequately exposed through the face exposure opening (Ab). That is, as shown in FIG. 3, if the face of the wearer (B) is excessively exposed from the face exposure opening (Ab), the head of the wearer (B) is sufficiently protected from contamination by foreign substances. and cannot adequately prevent the wearer (B) from contaminating the surroundings. On the contrary, if the face of the wearer (B) is not sufficiently exposed from the face exposure opening (Ab) as shown in FIG. (B) will not be able to perform smooth activities.

Especially in disposable protective clothing for medical use (A), for the purpose of preventing the size of the opening for exposing the face (Ab) from expanding excessively for the above reasons, the opening for exposing the face (Ab) Since elastic members (Ac) such as rubber cords are often attached to the periphery, the size of the face exposing opening (Ab) is often reduced inevitably, as shown in FIG. . However, especially for disposable medical protective clothing (A), it is necessary to supply a large amount of protective clothing with a certain size or shape at a low cost. It is difficult to form (Aa) preliminarily adapted to the size or shape of the head of each wearer (B).

Therefore, especially in the hood (Aa) of the medical disposable protective clothing (A) as described above, the size of the face exposure opening (Ab) can be adjusted in the vertical direction and the horizontal direction. It is desirable to have Conventionally, the following specific proposals have been made as a structure for adjusting the size of the opening for exposing the face in such a hood.

First, a plurality of belt loops are placed approximately in the center of the rear side of the hood, a draw cord is inserted through the belt loops, and the draw cord is tied or tightened to adjust the size. A hood has been proposed (see, for example, Patent Document 1 below).

In addition, a hood has been proposed in which belts are provided in the horizontal direction so as to adjust the size around the head of the hood, and belts are provided in the vertical direction so as to adjust the size of the height of the head of the hood. (See, for example, Patent Document 2 below.).

In addition, a stretchable device is formed around the face-exposing opening of the hood, and a similar adjustment device is set at the rear of the hood, and the device at the front opening of the hood has a stretchable elastic cord laterally. It is proposed to improve the hood so that it does not come into direct contact with the head and face, and the hood can be tightened vertically and horizontally by using a hook-and-loop fastener and a tightening elastic cord at the rear of the hood (for example, See Patent Document 3 below.).

According to the structure for adjusting the size of the opening for exposing the face in the hood according to the prior art as described above, the size of the opening for exposing the face is adjusted in the vertical direction and the horizontal direction, respectively, thereby adjusting the size of the wearer's face. It can be moderately exposed from the exposure opening. As a result, the wearer's head can be protected from contamination by foreign substances such as dust, etc., and the surrounding contamination can be prevented by preventing hair, skin fragments, etc. from falling from the wearer's head. (For example, see Patent Document 2 below.). In addition, since the wearer's field of view can be secured, the wearer can perform activities smoothly (see Patent Documents 1 and 3 below, for example).

JP-A-08-232109 Japanese Utility Model No. 63-102729 Utility Model Registration No. 3047628

However, the structure for adjusting the size of the opening for exposing the face in the hood according to the above-mentioned prior art does not allow the drawcord to pass through a plurality of belt loops arranged on the hood (see, for example, Patent Document 1), or the hood. Attaching two belts for adjusting the vertical direction and the horizontal direction respectively (see, for example, the above-mentioned Patent Document 2), or forming elastic devices around the front opening of the hood and at the rear, respectively, the former Since the latter uses a hook-and-loop fastener and a tightening rubber cord (see, for example, Patent Document 3), its structure is unnecessarily complicated. rice field. As a result, there is a problem that it takes time and money to manufacture a hood having such a structure for adjusting the size of the opening for exposing the face or clothing having the hood. In particular, such a problem is conspicuous in clothing such as disposable protective clothing for medical use as described above, which is inexpensive and needs to be supplied in large quantities. Therefore, the first problem to be solved by the invention of the present application is to provide a simple structure for adjusting the size of the opening for exposing the face in the hood in both the vertical and horizontal directions.

In addition, in the structure for adjusting the size of the opening for exposing the face in the hood according to the prior art, when adjusting the size of the opening for exposing the face, the draw cord inserted through the belt loop is tied or tightened. (see, for example, the above-mentioned Patent Document 1), the horizontal belt is tightened and narrowed to fit the hood to the size of the wearer's head circumference, and the vertical belt is attached to the hood. The hood can be adjusted to the size of the wearer's head height by lowering it until it reaches the top of the wearer's head (see, for example, Patent Document 2 above), or the wearer can pull the string and the blocking device While preventing the string from returning (for example, see Patent Document 3 above), such adjustment work is complicated. In particular, when putting on and taking off disposable medical protective clothing at medical institutions, it is sometimes necessary to wear gloves that are more difficult to put on and take off than with bare hands. Since the time required for attaching and detaching needs to be as short as possible, it is preferable to adjust the size of the opening for exposing the face as simply as possible. Therefore, the second problem to be solved by the invention of the present application relates to a structure in which the size of the face exposing opening in the hood can be adjusted in the vertical direction and the horizontal direction, respectively, and the adjustment work can be easily performed.

The string-like member (22) is temporarily removed from the vertical adjustment hook-and-loop fastener (21), and is re-adhered to the vertical adjustment hook-and-loop fastener (21) at a desired position closer to the free end than before, thereby exposing the face. By contracting the elastic member (Ac) attached to the periphery of the opening (Ab), the vertical size of the face exposing opening (Ab) can be narrowed. In addition, the string material for horizontal adjustment (32) is once removed from the hook-and-loop fastener for horizontal adjustment (31), and is attached to the hook-and-loop fastener for horizontal adjustment (31) at a desired position on the free end side than before. As a result, the lateral size of the face exposure opening (Ab) can be narrowed by contracting the elastic member attached to the peripheral edge of the face exposure opening (Ab).

On the other hand, if the face of the wearer (B) is not sufficiently exposed from the face exposure opening (Ab) after adjusting as described above, the string-like member (22) for vertical direction adjustment is temporarily moved in the vertical direction. By removing it from the adjusting hook-and-loop fastener (21) and re-adhering it to the vertical adjusting hook-and-loop fastener (21) at a desired position on the opposite side of the free end than before, the peripheral edge of the face exposure opening (Ab) By extending the attached elastic member (Ac), the longitudinal size of the face exposure opening (Ab) can be further increased. In addition, the horizontal adjustment cord-like member (32) is once removed from the horizontal adjustment hook-and-loop fastener (31), and attached to the horizontal adjustment hook-and-loop fastener (31) at a desired position on the opposite side of the free end than before. By bonding, the stretchable member (Ac) attached to the periphery of the face exposing opening (Ab) is stretched, thereby further expanding the lateral size of the face exposing opening (Ab).

In this way, the structure (1) for adjusting the size of the face-exposing opening in the hood allows the face-exposing opening to be adjusted simply by adhering the desired position of the longitudinally adjusting cord-like member (22) to the longitudinally adjusting hook-and-loop fastener (21). It is possible to adjust the size in the vertical direction in the part (Ab), and the face exposing opening can be opened simply by adhering the desired position of the horizontal adjustment string member (32) to the horizontal adjustment hook-and-loop fastener (31). Lateral size adjustments in (Ab) can be made. That is, the structure (1) for adjusting the size of the opening for exposing the face in the hood can be easily adjusted.

In particular, the size adjustment structure (1) for the face exposing opening of the hood has a free end on the side where the longitudinal adjustment string member (22) is adhered to the longitudinal adjustment hook-and-loop fastener (21). Since the end on the opposite side is fixed to the hood (Aa), it is possible to adjust the size in the vertical direction by attaching one end to the hook-and-loop fastener for vertical adjustment (21). , The end on the side where the horizontal adjustment string-like member (32) is adhered to the horizontal adjustment hook-and-loop fastener (31) is a free end, while the opposite end is attached to the hood (Aa). Since it is fixed, it is possible to adjust the size in the horizontal direction by adhering one end to the horizontal adjustment hook-and-loop fastener (31). By doing so, it is preferable that the size of the opening for exposing the face can be easily adjusted, as is necessary when putting on and taking off disposable medical protective clothing in a medical institution as described above.
