FIELD: automobile production. ^ SUBSTANCE: invention refers to double-purpose wiper for rain and snow for vehicle windshield. Wiper consists of flexible plate in a form of an arc, some clamping devices, strip scraper holder, cover, strip scraper, two limit protecting caps and seat. Cover and two limit protecting caps fully cover flexible plate in a form of an arc, clamping devices and strip scraper holder so that snow and ice particles are restrained and isolated outside and can not penetrate inside or accumulated in some empty area inside. Thus the necessity of weary changing of rain wiper to snow wiper in the period between snowy and non-snowy seasons is excluded. This not only allows the drivers to decrease additional expenses for snow wiper purchasing, but fully excludes the use of standard snow wipers that are attached to lever-holders and thus, decreases environment pollution caused by mass throwing out of traditional snow wipers. ^ EFFECT: thus it has double effect regarding economic benefit and environment protection. ^ 3 cl, 20 dwg |
