Description

【0001】
【発明の属する技術分野】
本発明は、顔部に装着して、目を粉塵、飛沫、風圧等から保護する防塵眼鏡に関するものである。
【0002】
【従来の技術】
従来のこの種の防塵眼鏡は、目の前方を包囲する眼鏡本体と、この眼鏡本体に取り付けた伸縮自在なバンドとから構成されている場合が多い。この防塵眼鏡を装着する際には、眼鏡本体を顔部に押し付けながらバンドを伸ばして頭部に嵌めている。一般に、眼鏡本体は目の前方に間隔をおいて位置する眼鏡部、この眼鏡部の左右の側縁から後方に延びて目の側方に当接する左右の側板部、眼鏡部の上縁から後方に延びて目の上方に当接する天板部、眼鏡部の下縁から後方に延びて目の下方に当接する底板部等を有している。
【0003】
【発明が解決しようとする課題】
しかしながら従来の防塵眼鏡では、眼鏡本体を顔部に押し付けながらバンドを伸ばして頭部に嵌めるので、装着が容易ではないという問題がある。更に、防塵眼鏡は頭部保護用ヘルメットと同時に装着する場合が多く、ヘルメットより先に防塵眼鏡を装着した場合は、ヘルメット挿着時に防塵眼鏡に接触してずれたり、また防塵眼鏡を外す場合はヘルメットの耳掛け紐が邪魔になるので、ヘルメットを脱がないと防塵眼鏡を外せないことになる。逆に、ヘルメットを先に装着した場合は、頭部より大きなヘルメットを手探りでかわすように、防塵眼鏡のバンドを後頭部まで持っていって掛けなくてはならず煩わしい。
【0004】
挿着後に防塵眼鏡が不要となった際は、眼鏡本体をヘルメットの前方に引っ張ってずらして、バンドの収縮力によってヘルメット前頭部付近に固定しておくことが一般的であるが、何かの拍子に眼鏡本体が滑って頂部の方にずれてしまい、邪魔であると共に危険性がある。このずれを防止するためにヘルメットに防塵眼鏡バンド固定金具を左右一対に取り付けてバンドを固定する方法も知られているが、この場合は金具がヘルメットから膨出する形態になるので、例えば建築作業中の現場の狭い通路を通過する際に、金具が引っかかってしまう虞れがあって危険であると共に、金具分のコストと重量がヘルメットに付加されてしまうことになる。
【0005】
更に、通常の防塵眼鏡では、眼鏡部の左右の側板部が後方に延びているので、耳掛け部も折り畳めず、ポケット等に簡便に収納することも容易でないという問題もある。
【0006】
本発明の目的は、上述の問題点を解消し、装着と収納が容易な防塵眼鏡を提供することにある。
【0007】
【課題を解決するための手段】
上記目的を達成するための請求項1に係る発明は、顔部に装着して目を保護する防塵眼鏡において、可撓性を有して目の前方を包囲する眼鏡本体と、該眼鏡本体に固定すると共に折り畳み可能な左右の耳掛け部とから成り、前記眼鏡本体の側板部と天板部に、前記耳掛け部を折り畳む際に作用する折れ代をそれぞれ設けたことを特徴とする防塵眼鏡である。
【0009】
請求項に係る発明は、前記側板部の前記折れ代の後方の部分を前記耳掛け部に連結した請求項1に記載の防塵眼鏡である。
【0010】
【発明の実施の形態】
本発明を図示の実施の形態に基づいて詳細に説明する。
図1は実施の形態の前方から見た斜視図、図2は後方から見た斜視図である。この実施の形態に係る防塵眼鏡は左右対称とされ、着用者の目の前方を包囲する眼鏡本体1と、この眼鏡本体1の上部を外側から支持するフレーム2とから構成されている。眼鏡本体1は合成樹脂材料から可撓性を有するように形成され、フレーム2は金属材料又は剛性を有する合成樹脂材料から製作されている。
【0011】
眼鏡本体1は、目の前方に間隔をおいて位置する透明な眼鏡部11と、この眼鏡部11の左右の側縁から後方に延びて目の側方に柔らかく当接する左右の側板部12と、眼鏡部11の上縁から後方に延びて目の上方に当接する天板部13と、眼鏡部11の下縁から後方に延びて目の下方に柔らかく当接する底板部14とを有している。
【0012】
眼鏡部11には例えば曇り防止用のコーティングが施され、天板部13と底板部14には、空気を流通させるが粉塵、飛沫等を流通させない小孔群15がそれぞれ形成されている。そして、眼鏡本体1とフレーム2を着脱自在に連結する一方の手段として、図示しない連結用孔が例えば眼鏡部11と側板部12に形成されている。
【0013】
フレーム2は、眼鏡本体1の眼鏡部11を支持する棒状の前方支持部21と、この前方支持部21の左右の両端から後方に一体に延びて眼鏡本体1の側板部12の前部を支持する側方支持部22と、この側方支持部22の後端にヒンジ部23を介して連結された耳掛け部24とから構成されている。眼鏡本体1の前方支持部21と側方支持部22には、眼鏡本体1とフレーム2を連結する他方の手段としての連結部25が、眼鏡部11と側板部12に形成した連結用孔にそれぞれ係止し得るように設けられている。なお、耳掛け部24はヒンジ部23に連結された筒部24aと、筒部24aに嵌合された耳掛け部本体24bとから構成され、耳掛け部本体24bは前後方向に伸縮自在かつ位置保持自在とされている。
【0014】
ここで、眼鏡本体1の側板部12と天板部13には、例えば連続溝状の折れ代31、32が、フレーム2のヒンジ部23の近傍を通るようにそれぞれ形成されている。また、眼鏡本体1の側板部12の後部とフレーム2の筒部24aとは、側板部12に一体で筒部24aを緩く包む連結部33により連結されている。
【0015】
このような防塵眼鏡をポケット等に収納する際には、図3の平面図に示すように耳掛け部24の耳掛け部本体24bを筒部24aに押し込み、耳掛け部24を最小の長さとして内方へ折り畳む。これにより、側板部12の折れ代31の後方の部分12aが、側板部12が持つ或る程度の弾発力に抗して耳掛け部24に押されて内方に折れ曲がると共に、天板部13の折れ代32の後方の部分13aが上方に折れ曲がる。この際に、側板部12と一体の連結部33は耳掛け部24を緩く包んでいるので、側板部12は耳掛け部24に対して摺動しながら容易に折れ曲がる。
【0016】
一方、防塵眼鏡を着用する際に耳掛け部24を開くと、耳掛け部24は連結部33を介して側板部12の折れ代31の後方の部分12aを従動させ、側板部12を平面状に復元させる。この際にも、側板部12は弾発性により耳掛け部24に対して摺動しながら容易に復元する。
【0017】
仮に、長時間折り畳まれた状態で放置されていても、耳掛け部24を緩く包む連結部33を介して側板部12は、耳掛け部24を開くときに連結部33が摺動しながら平面状に復元される。そして、耳掛け部24の長さを調節して耳掛け部24を耳に掛けると、眼鏡本体1の後縁が目の周りに密着し、着用者の目を風圧、粉塵、飛沫等から保護する。
【0018】
なお、実施の形態においては、耳掛け部24はフレーム2、側方支持部22と一体となっているが、フレーム2は省略することもできる。
【0019】
【発明の効果】
以上説明したように請求項1に係る防塵眼鏡は、可撓性を有して目の前方を包囲する眼鏡本体と、折り畳み可能な左右の耳掛け部を有して眼鏡本体を支持するフレームとから構成したので、耳掛け部を耳に掛けるだけで容易に装着できる。また、眼鏡本体の側板部と天板部に折れ代を設けたことにより、側板部の折れ代の後方の部分が折れ易くなり、耳掛け部を容易に折り畳むことができ、ポケット等に容易に収納できる。
【0021】
請求項に係る防塵眼鏡は、側板部の折れ代の後方の部分を耳掛け部に連結したので、耳掛け部を開いた際に側板部を元の状態に確実に戻すことができる。

BACKGROUND OF THE INVENTION
The present invention relates to dust-proof eyeglasses that are attached to a face to protect eyes from dust, splashes, wind pressure, and the like.
[0002]
[Prior art]
This type of conventional dustproof glasses is often composed of a spectacle main body surrounding the front of the eye and a stretchable band attached to the spectacle main body. When wearing the dust-proof glasses, the band is extended and fitted to the head while pressing the glasses main body against the face. In general, the spectacle body is a spectacle part positioned at an interval in front of the eyes, left and right side plate parts that extend rearward from the left and right side edges of the spectacle part and abut on the side of the eye, and rearward from the upper edge of the spectacle part. And a bottom plate portion that extends rearward from the lower edge of the spectacle portion and contacts the lower portion of the eye.
[0003]
[Problems to be solved by the invention]
However, the conventional dustproof glasses have a problem that they are not easy to wear because the band is extended and fitted to the head while pressing the spectacle body against the face. In addition, dustproof glasses are often worn at the same time as the head protection helmet.When wearing dustproof glasses prior to the helmet, the dustproof glasses may come out of contact with the dustproof glasses when the helmet is inserted. Since the helmet's ear straps get in the way, the dust-proof glasses cannot be removed without removing the helmet. On the other hand, when wearing a helmet first, it is cumbersome to carry the dust-proof eyeglass band up to the back of the head so as to fend off a helmet larger than the head.
[0004]
When dust-proof glasses are no longer needed after insertion, it is common to pull the glasses body in front of the helmet and shift it, and fix it near the front of the helmet by the contraction force of the band. The main body of the glasses slips and shifts toward the top, which is both an obstacle and a danger. In order to prevent this shift, there is also a method of fixing a band by attaching a pair of dustproof eyeglass band fixing brackets to the helmet, but in this case, the brackets are in a form that bulges from the helmet. When passing through a narrow passage on the site, there is a risk that the metal fitting may be caught, and the cost and weight of the metal fitting are added to the helmet.
[0005]
Furthermore, in normal dustproof glasses, the left and right side plate portions of the spectacles portion extend rearward, so that there is also a problem that the ear-hanging portion cannot be folded and cannot be easily stored in a pocket or the like.
[0006]
An object of the present invention is to solve the above-mentioned problems and to provide dustproof glasses that can be easily mounted and stored.
[0007]
[Means for Solving the Problems]
