Abstract

PURPOSE:To eliminate fogging and to prevent the entry of snow and dust by perforating numbers of small holes of about 0.2mm. as ventilators in an external edge consisting of the flank or top surface of a lens with a laser light beam. CONSTITUTION:A dust-protective frame 1 made of semihard plastic and a dust- protective frame 2 made of soft plastic are engaged in one body and the lens 4 is fitted in the frame 1. Then, numbers of small holes of about 0.2mm. are perforated as ventilators 5 and 6 in the external edge consisting of the flank or top surface of the lens 4 with the laser light beam. Those ventilators of the size allow air and vapor to flow, but prevent the entry of snow and dust, so that fogging is eliminated completely.

Description

【発明の詳細な説明】 くは防塵眼鏡及びヘルメットのシールド用の製法に関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a manufacturing method for shields for dustproof glasses and helmets.

、従来の防塵眼鏡等は、ベンチレーターの穴をドリル等
で穿設していたために、穴径が０，５〜１粍と大きく、
そのため雪や塵埃の潜入することが欠点となっていた。In order to eliminate fogging of dustproof glasses, etc., it is necessary to drill air holes in the transparent plastic lenses. However, in conventional dust-proof glasses, etc., the hole for the ventilator was drilled, etc., so the hole diameter was large, 0.5 to 1 mm.
As a result, the disadvantage was that snow and dust could infiltrate.

防塵眼鏡の製法の一実施例を説明する。In view of the circumstances, the present invention has been developed to reduce the hole diameter of the ventilator to 0.
．． The purpose of this invention is to provide a method for manufacturing dust-proof glasses, etc., which requires less than 5 wear. Hereinafter, an embodiment of the method for manufacturing dustproof glasses of the present invention will be described based on the drawings.

ラスチック製のレンズである。(1) is a dustproof frame made of semi-hard plastic, (21 is a dustproof frame made of soft plastic, and the two are integrated by fitting together.) (3) is a wire mesh covering the window on the dustproof frame. , and (4) is a transparent plastic lens fitted inside the dustproof frame (1).

6)... (6) is a ventilator made from a large number of small holes drilled in the outer edge of the upper surface of the lens (4), each of which has a diameter of about 0.2 mm drilled by the laser beam. This point is a feature of the gluing method of the present invention. The manufacturing method of the present invention can be applied to helmet shields in addition to the above embodiments.

等の用途に適用しうる有用なものである。Since the method for manufacturing dustproof glasses of the present invention has the above-described structure, air and water vapor can flow through the glasses, but snow and dust do not enter at all, so fogging can be completely eliminated. The dust-proof goggles manufactured by the method of the present invention are suitable not only as goggles for skiing but also useful as shields for helmets and the like.
