Description

  The present invention relates to an insect cover that covers the entire face and head in order to protect the face and head from pests when extinguishing bees and other pests.

  One of such insect repellent covers is described in Japanese Patent Application Laid-Open No. 2004-204390.

  FIG. 3 is a schematic perspective view of the insect-proof cover described in the publication.

  The conventional insect repellent cover 100 shown in FIG. 3 includes a head 101, a transparent plate 102, and an insect repellent cover main body 103, and this insect repellent cover 100 is connected to the insect repellent clothing main body 105 via a fastener 211C. ing.

  The transparent plate 102 is made of a cylindrical transparent resin, and can ensure a 360-degree field of view.

  A head 101 made of a net material is formed above the transparent plate 102, and a through hole 107 that can be fitted to the helmet 106 is provided at the top of the head.

  Below the transparent plate 102, an insect repellent cover body 103 made of a net material is provided.

  The head 101, the transparent plate 102, and the insect-proof cover main body 103 are detachably connected via fasteners 211A and 211B.

  However, the conventional insect-proof cover 100 has the following problems.

  The first problem is that a 360-degree field of view may not always be ensured.

  Since the transparent plate 102 is made of resin, it does not have air permeability. For this reason, when the internal humidity increases, the transparent plate 102 may become cloudy, or the transparent plate 102 may become cloudy due to a breath exhaled by the user, and conversely, the visibility may be deteriorated. In other words, the surroundings are made 360 degrees transparent with emphasis on visibility, but this is the cause of hindering visibility.

  The second problem is that the working environment may be deteriorated.

  As described above, since the transparent plate 102 is made of resin, it is non-breathable and has low heat conductivity. That is, the transparent plate 102 does not allow air to pass through and does not release heat. For this reason, heat tends to accumulate inside the transparent plate 102. In particular, when the work is carried out by covering the insect-proof cover 100 on a hot and humid day such as summer, heat accumulates inside the transparent plate 102, causing the worker to sweat a lot and lowering the work efficiency.

  The present invention has been made in view of the problems in the conventional insect repellent cover as described above, and provides an insect repellent cover that can reliably ensure visibility and does not cause deterioration of the working environment. For the purpose.

  Hereinafter, means for solving the above-described problems will be described using reference numerals used in “Embodiments of the Invention”. These reference numerals are added only for the purpose of clarifying the correspondence between the description of “Scope of Claim for Utility Model Registration” and the description of “Mode for Invention”. It should not be used to interpret the technical scope of the device described in the claims.

  In order to achieve the above object, the present invention provides an insect repellent cover (500) that covers a user's head and face, and has a through-hole having a size capable of fitting a helmet (700) worn by the user. 511), a transparent plate member (520) extending downward from the outer peripheral edge in at least half of the outer peripheral edge of the annular member (510), and the annular member In the remaining region of the outer periphery of (510), the mesh member (530) extending downward from the outer periphery, the transparent plate member (520), and the mesh member (530) are continuously connected to the transparent plate member. And an insect repellent cover body (540) extending below the mesh member (530) and covering at least the neck of the user. .

  In the insect repellent cover (500) according to the present invention, the mesh member (530) preferably has an N layer structure (N is an integer of 2 or more) composed of N mesh layers. In this case, it is preferable that the outermost mesh layer has the largest hardness, and the innermost mesh layer has a lower hardness.

  The center of the through hole (511) is preferably eccentric to the mesh member (530) side than the center of the annular member (510).

  In the insect repellent cover (500) according to the present invention, a region of the insect repellent cover main body (540) located below the transparent plate member (520) may be formed of a mesh member. For example, the mesh member has a two-layer structure including an outer mesh layer positioned on the outer side and an inner mesh layer positioned on the inner side, and the outer mesh layer is harder than the inner mesh layer.

  The annular member (610) is at a distance such that a space for sandwiching the collar (701) of the helmet (700) is formed below the first annular member (611) and the first annular member (611). It can comprise from the 2nd annular member (612) spaced apart.

  The insect repellent cover (600) according to the present invention includes at least one rigid core member (613) that supports at least one of the first annular member (611) and the second annular member (612). it can.

  The insect repellent cover according to the present invention has the following effects.

  First, it makes it possible to ensure visibility.

  In the conventional insect-proof cover 100 shown in FIG. 3, when the humidity inside the transparent plate 102 increases, the transparent plate 102 becomes cloudy, and the visibility to the surroundings may be reduced. On the other hand, in the insect repellent cover according to the present invention, a mesh member is arranged around a part of the user's face, so moisture inside the insect repellent cover is released to the outside through this mesh member. In addition, low-humidity air is introduced from the outside into the inside of the insect-proof cover.

  Thus, according to the insect repellent cover according to the present invention, the mesh member 530 can always perform ventilation between the air inside the insect repellent cover and the outside air, so that moisture does not accumulate inside the insect repellent cover. As a result, unlike the conventional insect repellent cover 100, the transparent plate member is not fogged, and thus visibility can be prevented from being hindered.

  Second, it is possible to prevent deterioration of the user's work environment.

  The conventional insect-proof cover 100 shown in FIG. 3 has a problem that heat tends to accumulate inside the transparent plate 102 because the transparent plate 102 is non-breathable and low in heat transfer.

  On the other hand, according to the insect repellent cover according to the present invention, the air inside the insect repellent cover is always replaced with the outside air via the mesh member, so that heat can be prevented from accumulating inside the insect repellent cover. For this reason, even if the user wears an insect repellent cover according to the present invention and works on a hot and humid day such as summer, an unnecessary temperature rise inside the insect repellent cover is prevented, and the work environment of the user is deteriorated. It is possible to prevent the user's work efficiency from being lowered.

  In the insect cover according to the present invention, the mesh member is configured to have a two-layer structure including an outer mesh layer and an inner mesh layer. In this case, the outer mesh layer is harder than the inner mesh layer. Can be set as follows. Since the inner mesh layer is softer than the outer mesh layer, even when the inner mesh layer touches the user, it is possible to prevent deterioration of the user's tactile sensation. Furthermore, since the outer mesh layer is harder than the inner mesh layer, the outer mesh layer can maintain the rigidity of the entire mesh member.

It is a perspective view which shows the condition where the insect-proof cover which concerns on 1st embodiment of this invention is used. FIG. 2A is a partial cross-sectional view of the insect-proof cover according to the second embodiment of the present invention, and FIG. 2B shows the positional relationship between the first annular member, the second annular member, and the core material.
