Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a protective cover used by people wearing eyeglasses for correcting vision such as myopia, astigmatism, presbyopia, etc. (hereinafter referred to as eyeglasses) by attaching them to helmets used at various construction sites and manufacturing factories.

[0002]

[Prior art]

 2. Description of the Related Art Conventionally, a safety helmet for protecting a head (hereinafter simply referred to as a helmet) has been used in various construction sites, manufacturing factories, and other dangerous workplaces. For example, when handling a high-speed rotating body such as a lathe, safety glasses are used in addition to a helmet to protect the eyes from flying foreign substances such as metal scraps (see, for example, Japanese Utility Model Application Laid-Open No. 2-6). 6635). However, when wearing glasses, normal safety glasses cannot be worn repeatedly.

[0003] Therefore, special safety glasses have been proposed which cover the glasses with a larger capacity than ordinary safety glasses. As shown in FIG. 4, a safety cover C formed of a transparent plastic plate having a size sufficient to completely cover the lens portion of the glasses and having a concave cross section is attached to the eaves H1 of the helmet H. There has also been proposed one that is movably attached with a mounting bracket T.

[0004]

[Problems to be solved by the invention]

 However, in the above-mentioned conventional example, since the lens of the glasses and the safety glasses or the safety cover are completely overlapped and completely cover both sides of the lens, the field of view becomes narrow and the perspective becomes worse. Therefore, there is a problem that sufficient attention to surrounding machines and hazardous materials may not be obtained, resulting in a considerable decrease in work safety, sometimes causing discomfort, and consequently causing a decrease in visual acuity. is there. Further, in the latter case, there is a gap S between the upper side of the safety cover and the eaves of the helmet, so that there is also a problem that scattered foreign matter enters the eyes through this gap.

[0005] The present invention solves the above-mentioned problems of the prior art, and provides a protective cover that can be easily worn by even a person wearing glasses to protect the eyes and that does not cause a decrease in visual acuity. As an issue.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, the protective cover of the present invention has been improved on the premise that the protective cover is a type that is attached to the eaves of a helmet worn by a spectacle user. In other words, the front surface is formed by forming an elongated thin plate so that the upper side has a shape substantially along the lower surface of the eaves portion of the helmet, and the lower side has a shape substantially along the contour of the upper side portion and both side portions of the spectacle frame. Attachments that constitute a shielding part and a side shielding part, and that can be attached to a part of the front shielding part such that the front shielding part and the side shielding part can be attached to the eaves of the helmet so as to hang down from the eaves of the helmet. It is characterized by being provided.

[0007] According to the present invention, the front shield prevents the scattered foreign matter from entering from above the glasses, and the side shield prevents the scattered foreign matter from entering from the side of the glasses.

[0008]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings.

As shown in FIG. 1 and FIG. 2, the protective cover 1 of the present invention has substantially inverted trapezoidal side shielding portions 3 on both sides of a substantially rectangular front shielding portion 2 having a required size. It is connected integrally so as to bend at a right angle and hang down. As shown in FIGS. 3 (a) and 3 (b), the protective cover 1 is attached to the eaves H1 of the helmet H by a mounting tool M provided on a part of the front shield 2. When the eyeglass user wears a helmet, the front shielding part 2 is provided between the eaves H1 of the helmet and the upper side of the glasses G when the user wears the helmet. , And the side portions of the glasses from the eaves H1 of the helmet to the vicinity of the outer corner of the eyes are shielded by the side shields 3, 3.

As a material of the protective cover 1, a thin flat plate made of an acrylic resin is used. However, the material is not limited to this, and any material having light weight, strength, durability, workability, etc. may be used. For example, thermoplastic resins such as high-density polyethylene, polyvinyl chloride, polycarbonate, and polyamide are preferred. In this case, it is preferable to use a transparent colored material because, for example, “welding burn” during welding work can be prevented.

Further, the shape of the protective cover 1 is such that the front shielding portion 2 is substantially rectangular and the side shielding portion 3 is substantially trapezoidal in a substantially horizontal direction, but is not limited to this. When all the helmets are worn, it is sufficient that the front shielding portion 2 has a size and shape sufficient to cover approximately the lower half of the forehead (a gap formed between the eaves portion of the helmet and the upper side of the lens or lens frame). It is only necessary that the side shielding portion 3 has a size and shape sufficient to cover from the temple to the periphery of the outer corner of the eye (a gap generated from the eaves portion of the helmet to the portion around the vine shaft). Furthermore, it is preferable that the front side portion of the side surface shielding portion 3 covers at least the upper half without covering the entire lateral portion of the lens frame, so that the side view of the glasses is not narrowed, which is preferable. In addition, chamfering may be performed on the corners of the side shielding portion.

The mounting fixture M has one end of a substantially L-shaped fitting fixed to a part of the front shielding portion, and a clip provided at the other end so as to be able to be clamped to the eaves portion of the helmet, but is not limited to this. Instead, for example, a mounting piece may be provided on a part of the cover, and buttons or hook-and-loop fasteners may be provided on the mounting piece and the lower part of the eaves of the helmet to make the cover detachable. Further, it is preferable to pivotally attach the L-shaped bent portion of the mounting portion via a shaft, since the user can freely adjust the mounting angle of the protective cover.

[0013]

【Example】

 Using a 2 mm thick flat plate made of acrylic resin, both ends are cut down to the required shape, bent or curved downward, and then deformed by hot pressing so that both ends have an angle of about 105 degrees with the center. Thus, a desired protective cover was formed in which the front shielding portion and the side shielding portion were integrally connected. The lower end of the side shield was chamfered. Next, a fixture consisting of an L-shaped bracket was fixed to the front shield by inserting rivets into small holes provided substantially at the center of the front shield and small holes provided at the other end of the fixture. In addition, a clip is provided at the other end of the attachment so that the attachment can be sandwiched between the eaves of the helmet. Further, the L-shaped bent portion of the fixture is pivotally connected via a shaft so that the angle of the cover can be adjusted.

[0014]

[Effect of the invention]

 The protective cover of the present invention can be easily attached to a helmet, and can prevent flying foreign substances from entering the eyes through a gap between the glasses and the helmet. Further, since the lens does not have the “double lens” as in the prior art, the perspective is not hindered, and the discomfort does not occur, and the person wearing glasses can wear it without trouble. Therefore, there is no reduction in vision or safety. As described above, the present invention exerts an excellent effect on safety and health in work.
