Description

  The present invention relates to a dust-proof hood worn by workers engaged in the manufacture of medicines, foods, etc. for the purpose of preventing foreign matters from entering products, and in particular, equipped with a transparent shield that covers the face opening. It relates to a dust hood.

  When manufacturing chemicals and foods, dust-proof clothing and dust-proof hoods are used from the viewpoint of hygiene management. There are various types of dust-proof hoods, which have large openings that expose the entire wearer's face, and those that have openings that expose only the wearer's eyes and nose. and so on. In addition, as a dust-proof hood used in environments where higher levels of hygiene are required, a transparent plastic shield is attached to the opening where the eyes and nose of the wearer are exposed, and the eyelashes and eyebrows of the wearer are products. There is also a dust-proof hood with a shield that can prevent contamination.

  A dustproof hood with a shield is generally attached so that the shield can be freely attached to and detached from the hood body. This is because the dust-proof hood is used from the viewpoint of hygiene management and therefore needs to be washed regularly, and if it is washed with the shield attached, it is easily damaged.

Japanese Patent Laid-Open No. 10-127797

  A conventional dustproof hood with a shield employs a button-type fitting hook as a means for fixing the shield to the hood body. More specifically, hooks are attached to 3 to 4 places near the upper edge and the lower edge of the shield, and the shield is fitted by fitting into hooks attached to the corresponding places of the hood main body. Can be fixed to the hood body and can be easily removed.

  However, when using a button-type fitting hook as a means for fixing the shield, the shield will be supported by `` dots '', so if deformation occurs in the hood body during work or when removing and attaching the dust hood, The stress is concentrated around the hook of the shield, and there is a problem that it is bent and white streaks enter or breaks.

An opening that exposes the eyes of the person and its peripheral part is formed, and the support is attached to the main body so as to cover the peripheral part from the outside or inside with the opening of the main body as the center, and corresponds to the opening of the main body An opening is formed at a position where the upper side and the lower side are fixed to the main body, and at least one of the right side and the left side is not fixed to the main body, or the fixed state can be released. The shield is configured so that the shield can be inserted into the space between the main body and the support from the right side or the left side.

  Further, the dust-proof hood according to claim 2 of the present invention includes a top portion covering the wearer's head top portion, a front portion covering the wearer's face portion, a rear portion covering the wearer's back head, a wearer's chest, And a lower portion covering both shoulders, and the front portion is connected to either the top portion, the rear portion, or the lower portion via a connecting portion at a part of the outer edge portion, and the outer edge portion. The part other than the connection part is connected to the top part, the rear part, and the lower part in a state that can be opened and closed by the fastener, and is configured so that the entire face of the wearer can be exposed by opening the fastener. It is characterized by being.

  The dust-proof hood according to claim 3 of the present invention includes a top portion covering the wearer's head, a front portion covering the wearer's face, a rear portion covering the wearer's back, a wearer's chest, And a lower part covering both shoulders, and the front part is connected to the top part through the connection part in a part of the outer edge part, and the part other than the connection part in the outer edge part Is connected to the top, rear, and lower part in a state that can be opened and closed by a fastener, and by opening the fastener, the lower edge side of the front part is lifted from the connection part as a base point, and the whole is lifted and placed on the top And by engaging an engaging means (for example, a hook) provided on the front surface portion with an engaging means formed on the rear portion or the outside of the top portion, Can be kept on the surface It is characterized by being composed urchin.

  Furthermore, in the dustproof hood according to claim 4 of the present invention, a forehead wound around the head of the wearer at the time of wearing is attached to a position inside the upper part of the main body of the front surface. It is characterized in that a desired space is formed between the front part including the shield and the face of the wearer. In this dustproof hood, a means for changing the inner peripheral dimension of the forehead pad (for example, an adjuster belt) is attached to the rear part so that the winding state of the forehead pad around the wearer's forehead can be freely adjusted. It is preferable to configure.

  Further, the dust-proof hood according to claim 6 of the present invention is a dust-proof hood having a front surface portion that covers a wearer's face portion, and the front surface portion is constituted by a main body, a support, and a transparent shield, The body is formed with an opening that exposes the wearer's eyes and the peripheral portion thereof, and the support is attached to the body so as to cover the periphery from the outside or the inside with the opening of the body as the center.

FIG. 1 is a front view of a dust-proof hood 1 (first embodiment) according to the present invention. FIG. 2 is a side view of the dust-proof hood 1 of FIG. FIG. 3 is a diagram illustrating a state in which the fastener 7a is opened (a state in which the outer edge portion of the front surface portion 4 is not connected to other parts) in the dustproof hood 1 of FIG. FIG. 4 is a view showing a state in which the front surface portion 4 is lifted and placed on the top portion 2.

  Hereinafter, embodiments of the “dust-proof hood” of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a front view of a dust-proof hood 1 (first embodiment) according to the present invention, and FIG. 2 is a side view thereof. As shown in the figure, the dust-proof hood 1 has a structure that covers the entire head from the wearer's head to both shoulders, and a top 2 that covers the top of the wearer's head, and the back of the wearer's back , A front part 4 covering the face part extending from the wearer's forehead to the throat, and a lower part 5 covering the wearer's chest, upper back and both shoulders.

  The front surface portion 4 is permanently connected to the top portion 2 via the connection portion 6 in the central portion of the upper edge (part of the outer edge portion), but the other portions of the outer edge portion are opened and closed by a single fastener 7a. It is connected with the top part 2, the rear part 3, and the lower part 5 in a possible state. More specifically, when the slider 7b of the fastener 7a is located at the end position on the left side (the left side in FIG. 1) of the connecting portion 6 shown in FIG. 6 is connected to the lower edge portion of the top portion 2 via the fastener 7a. Similarly, both side edge portions of the front surface portion 4 are connected to both side edge portions of the rear portion 3, and the lower edge portion of the front surface portion 4 is lower. 5 is connected to the upper edge portion.

  On the other hand, when the slider 7b of the fastener 7a is moved from the position shown in FIG. 1 around the outer edge portion of the front surface portion 4 to the right end position of the connecting portion 6, as shown in FIG. The outer edge portion of the portion 4 is not connected to the top portion 2, the rear portion 3, and the lower portion 5 except for the connecting portion 6. From this state, if the lower edge side of the front surface portion 4 is lifted up with the connecting portion 6 as a base point, the whole is scooped up, and the front surface portion 4 is placed on the top portion 2 as shown in FIG. The entire face can be exposed.

  In the dust hood 1, when the front surface portion 4 is lifted and placed on the top portion 2, the hook 10 a (see FIG. 3) provided at the lower left corner of the front surface portion 4 is placed outside the rear portion 3. It is possible to maintain the state where the front surface portion 4 is placed on the top portion 2 by being fitted into the hook 10b (see FIG. 4) formed on the top. In FIG. 4, the back side portion of the hook 10 b is shown, and the front side portion of the hook 10 b fitted to the hook 10 a of the front surface portion 4 is formed outside the rear portion 3.

  As shown in FIG. 3, the front surface portion 4 is constituted by a main body 4a, a substantially rectangular support 4b, and a plastic transparent shield 4c. The main body 4a is formed with an opening 4d (rectangular cutout) that exposes the wearer's eyes and the peripheral portion thereof in order to ensure the wearer's field of view. The support 4b is attached to the main body 4a so as to cover the peripheral portion around the opening 4d of the main body 4a from the outside, and the support 4b is located at a position corresponding to the opening 4d of the main body 4a (substantially the same as the opening 4d). An opening 4e (of the same size and shape) is formed.

  The support 4b has an upper side A, a lower side B, and a left side C (left side in FIG. 3) sewn (fixed) to the main body 4a, but the right side D (right side in FIG. 3) It is not fixed and is free with respect to the main body 4a. That is, the support 4b is configured as a pocket having the right side D as an entrance, and the shield 4c can be inserted into the space between the main body 4a and the support 4b from the right side D side. .

  The shield 4c inserted into the space between the main body 4a and the support 4b is firmly held in a state sandwiched between the main body 4a and the support 4b, and when inserted, the shield 4c Since the opening 4d and the opening 4e of the support 4b are formed so as to be able to block the entire opening 4e, the wearer's eyelashes, eyebrows, and other foreign objects may cause the openings 4d and 4e to It can be suitably prevented from passing through and spreading out of the dustproof hood.

  As shown in FIG. 4, when the dust-proof hood 1 is worn, the forehead rest 8 (abutting from the wearer's forehead to the vicinity of the top of the temple and wound around the head is located at the upper position inside the main body 4a. Is attached. The forehead pad 8 is composed of a mesh bag 8a and a cushion material 8c (elastic material) accommodated in the bag 8a. The upper edge 8d of the bag is sewn to the lower edge of the top 2. (Fixed), and both end portions 8b, 8b are sewn (fixed) to the rear portion 3, respectively.

  The cushion material 8c has a height dimension of about 5 cm, a width dimension of about 24 cm, and a thickness dimension of about 2 cm. The cushion material 8c is disposed in a front portion that abuts the wearer's forehead. When the dust hood 1 is worn so as to come into contact with an appropriate position, the front surface portion 4 including the shield 4c is formed by the cushion material 8c set to a sufficient thickness (preferable thickness dimension of the cushion material 8c: 1 to 4 cm). And a desired space (gap) is formed between the wearer's face. That is, the cushion material 8c to the forehead support 8 function as a spacer that forms a space between the shield 4c and the wearer's face.

  When the shield 4c is in a position very close to the wearer's face at the time of wearing, the shield 4c comes into contact with the face at the time of work and feels annoying, or sebum or foreign matter adheres to the shield 4c and hinders visibility. Or, there is a problem that the shield 4c is clouded by exhalation from the nose, but such a problem can be suitably avoided by the cushion material 8c functioning as a spacer.

  When the dust guard hood 1 is worn, if the forehead pad 8 is attached to an appropriate position of the wearer's forehead, the forehead pad 8 to the cushion material 8c are curved and follow along the curved surface of the wearer's forehead. Accordingly, the upper edge portion of the bag body 8a that accommodates the cushion material 8c is similarly curved. And the lower edge part of the top part 2 to which the upper edge part of the bag body 8a is fixed, and also the upper edge part of the front part 4 connected to the lower edge part of the top part 2 via the fastener 7a are the same. The front surface portion 4 is curved, and the inner surface near the upper edge portion is in contact with and integrated with the forehead pad 8, and unless the external force is applied, the front surface portion 4 is in a state where no “displacement” easily occurs. It will be in the state where front part 4 was held in the outside.

  Therefore, as long as the forehead support 8 does not deviate from the proper position of the wearer's forehead, the relative positional relationship between the front face 4 and the wearer's face does not change, and the front face 4 is not affected by the movement of the wearer's head. It will follow. As a result, the openings 4d and 4e of the front surface portion 4 should always be positioned at the front center of the wearer's field of view even when the wearer moves the neck left and right or looks up. Thus, the visibility is ensured.

  Further, as shown in FIG. 2, the adjuster belt 9 (the inner peripheral dimension of the forehead pad 8) is disposed on the outer surface of the rear part 3 at substantially the same height as the both ends 8 b and 8 b (see FIG. 4) of the forehead pad 8. Adjusting means), and by adjusting the length of the adjuster belt 9 (by loosening or squeezing it), the inner peripheral dimension of the forehead pad 8 can be changed. The winding state of the forehead pad 8 around the forehead can be freely adjusted (from a loose state or a tight state to an appropriate state). The means for changing the inner circumferential dimension of the forehead pad 8 is not limited to the adjuster belt 9 having the above-described configuration, and any configuration can be used as long as the inner circumferential dimension can be changed. May be.

  Furthermore, the support 4b is set to a dimension (32 cm in the present embodiment) such that the left side C and the right side D reach a position corresponding to the wearer's temple or ear when worn, such dimensional characteristics. (Suitable width dimension of the support 4b: 20 to 40 cm) and the support 4b (and the support 4b in the main body 4a overlap with the support 4b by the action of the follower pad 8 that curves along the curved surface of the wearer's forehead. The portion) is in a curved state corresponding to the face of the wearer from the center position corresponding to the wearer's nose bridge to the left side C and the right side D. Due to the curved state of the support 4b (and the main body 4a), the force (frictional force) between which the main body 4a and the support 4b clamp the shield 4c is increased, and the shield 4c is prevented from being detached or displaced when worn. On the other hand, when the dust-proof hood 1 is not worn by the user and when the fastener 7a is completely opened, the support 4b and the main body 4a can be flattened. It can be easily taken out from the inside of 4b.

  The shield 4c is a conventional dustproof hood in which the shield is supported by "points" as a result of being held on the "surface" by the main body 4a and the support 4b in all parts except the parts corresponding to the openings 4d and 4e. Problems such as “bending” or “cracking” due to stress concentration can be preferably avoided.

  In this embodiment, most parts except the shield 4c, the fastener 7a, the slider 7b, the cushion material 8c, and the hooks 10a and 10b are made of mesh material (the size of the eyes is hair, eyebrows, eyelashes, etc.). Doughproof mesh that is partly or wholly needed, if intended for use in spaces where higher cleanliness is required. It is also possible to use a material fabric or a dust-proof material fabric having a very fine texture.

  In the present embodiment, the support 4b is in a free state in which only the right side D is not fixed to the main body 4a, but is replaced with the left side C, and the right side D is fixed to the main body 4a. It is also possible to make C free without being fixed. Further, both the left side C and the right side D may be in a free state without being fixed to the main body 4a. Furthermore, the upper side A and the lower side B do not necessarily need to be fixed continuously over the entire length, and may be sewn partially or intermittently. The support 4b may be attached to the main body 4a in a detachable state. Furthermore, the left side C and the right side D can be fixed to the main body a, and either the upper side A or the lower side B can be fixed to the main body 4a without being fixed, or the fixed state can be temporarily released. You may comprise so that the shield 4c can be inserted in the space between the main body 4a and the support 4b from the upper side A side or the lower side B side.

  Moreover, in this embodiment, although the support 4b is attached to the outer side of the main body 4a, you may make it attach to the inner side. Further, the front surface portion 4 is connected to the top portion 2 via the connection portion 6 at the upper edge, but may be configured to be connected to the rear portion 3 at the side edge or the lower portion 5 at the lower edge.

  Further, in the present embodiment, the forehead pad 8 is configured by the bag body 8a and the cushion material 8c accommodated in the bag body 8a, but is configured by a single material having a desired elastic force. You can also.
