آشنایی با بدنه عینک

تاریخ:یکشنبه 4 خرداد 1393-09:41 ق.ظ

در این بحث قصد داریم در مورد اجزاء یک عینک آفتابی خوب صحبت کنیم آن قسمت از عینک، که عدسی‌های تجویز شده ویا تیغه‌های حفاظتی را در مقابل چشمان نگه می‌ دارد، قاب یا بدنه­ی عینک می‌ گویند و به فریم (Frame) نیز معروف است. فریم، توسط‌ دسته‌ هایی که به آن متصل می‌ شود، بر روی صورت تنظیم می‌ گردد. فریمهایی هم هستند که دسته ندارند و در عوض به وسیله­ی فشارهای دو طرف بینی در محل خود قرار می گیرند(مثل pince-nez یا oxford) ویا بر روی فریم دیگری سوار می شوند(مثلclip-ons) و یا در دست نگه داشته می شوند(مثلlorgnettes).

اجزای جلویی فریم (Frame Front)

آن بخش از قاب را که بین دو عدسی و بر روی بینی قرار می‌ گیرد را پل(Bridge) گویند و لبه‌ ای که دور عدسیهـا را در بر گرفته، به حدقه (Rim) یا (Eyewire) معروف است‌. به قسمتهای بیرونی جلوی قاب که درمنتها الیه سمت چپ و راست، در نقاطی که دسته ها به آنها متصل می شوند، Endpiece می گویند.

تعداد معدودی از فریمهای پلاستیکی، هنوز هم دارای یک پوشش فلزی در قسمت بیرونی Endpiece بوده که پرچهایی جهت نگهداری لولا به آنها متصل شده است.(شکل زیر)

لولاها، دسته ها را به قاب عینک متصل می‌کنند و تعداد پایه هایشان فرد است. تعداد پایه ها، سه، پنج و یا هفت است. لولا ها ممکن است که از نظر ساختمان با هم تفاوت داشته باشند.

 اما، به منظور ساده نمودن، آنها را معمولاً بر اساس تعداد پایه های لولای دسته ولولای قاب طبقه بندی می کنند. نسبت پایه ها مابین دسته و قاب متغیر می باشد. مثلاً، 2به1، 1به2، 3به2، 2به3، 4به3 و3به4.(برای مثال، اگر دسته، دارای یک پایه باشد، آنگاه قاب عینک دو پایه دارد و بر عکس اگر قاب عینک دارای دو پایه باشد، دسته می بایست یک پایه داشته باشد.)

بعضی از فریمها دارای پد(Pad) می باشند. پد، قطعه ای پلاستیکی است که بر روی بینی قرار می گیرد، تا فریم را نگه دارد. پدها ممکن است که، به­طور مستقیم و یا با واسطه­ی یک قطعه­ی فلزی که به بازوی محافظ و یا بازوی پد موسوم است، به فریم متصل شوند.


دسته ها (Temples)


فروش عینک آفتابی آن قسمت از دسته که نزدیکترین فاصله با قسمت اتصال با قاب را دارد، به butt end ویا butt portion معروف است. اولین نقطه ای از دسته که بر روی گوش خم می شود bend نامیده می شود. بخشی از دسته را که مابین butt end و bend قرار گرفته shank و یا shaft می نامند. آن بخش از دسته که در زیر bendودر پشت گوش قرار دارد، به نامهای earpiece, bend-down portion, curl معروف می باشد. پایه­ی لولای دسته را گاهی هم dowel hole می نامند.(شکل زیر)

I have been surfing online more than 2 hours today, yet I never found any interesting article like yours.
It's pretty worth enough for me. In my opinion, if all webmasters and bloggers made good content
