VEHICLE WINDSHIELD WIPER FOR RAIN AND SNOW DUAL PURPOSE
First Claim
1. A dual purpose vehicle windshield wiper for rain and snow comprises:
- a bow elastic strip, made of a downwardly bowed elastic metal strip, has a pair of lengthwise symmetrical rivet bores punched in the center thereof and a plurality of round holes punched and distributed in even space manner endwise as well as some oblong hollow pressure adjusting vents perforated thereon;
some detachable clamping devices, corresponding to said round holes on the bow elastic strip, each have a hollow round jut with an aperture being slightly smaller than that of a corresponding one of the plurality of round holes configured in a center of a top side and a pair of parallel symmetrical bent inwards clamping angles juxtaposed downwards at a bottom portion thereof;
a strip scraper receptacle, made of flexible plastics by unitary-molding into an integral body with a shape of a flat hollow bar, has a central parallel elongated gap extending through both ends and a pair of parallel symmetrical bent inwards hooked jut strips juxtaposed along both longitudinal lateral sides of the elongated gap as well as a snap-on hole respectively punched at each end thereof;
a sheath cover, made of flexible elastic material by unitary-molding into an integral body with a shape of a tubular hollow bar, has a flat surface formed on an upper portion with a long central attachment plus two short end attachments and a pair of parallel symmetrical elongated flutes juxtaposed inside of both internal longitudinal lateral sides for receiving the bow elastic strip as well as an elongated groove extending through both ends thereof;
a strip scraper, made of flexible elastic material by unitary-molding into an integral body, has a pair of parallel symmetrical elongated grooves juxtaposed outwards along both longitudinal lateral sides for receiving the pair of said hooked jut strips on the strip scraper receptacle and a pair of parallel symmetrical elongated jut strips connected together and juxtaposed above thereof along an upper portion as well as an elongated scraper blade having a downwardly oriented ridge configured at a bottom portion thereof;
two end ferrule caps, hollow cuboid in form and having a front open end and a back close end, a sectional shape of the open end correspondingly shaped with a size slightly bigger than that of the sheath cover and a horizontal elastic snap-on nose facing said open end configured inside a wall of said close end; and
a truss saddle, configured to fix the wiper on an end of a wiper arm via a wiper jointer, has flat bottom to closely affix on the long central attachment of the sheath cover and firmly riveted together with the bow elastic strip by two rivets.

Abstract
The present invention is to provide a “vehicle windshield wiper for rain and snow dual purpose”, which comprises a bow elastic strip, some clamping devices, a strip scraper receptacle, a sheath cover, a strip scraper, two end ferrule caps and a truss saddle; Wherein, the sheath cover and two end ferrule caps totally envelope the bow elastic strip, clamping devices and strip scraper receptacle so that the snow and icy particles are blocked and separated out unable to intrude or gather in any space thereof; Thereby, the dual function of rain wiper and snow wiper of present invention eliminates the boring action in swapping between rain wiper and snow wiper during interim of snow and non-snow seasons so that it not only saves the extra expense in buying snow wiper for the consuming vehicle drivers but also totally obsoletes the conventional arm-supported snow wiper so as to eliminate the pollution burden incurred by the mass waste conventional snow wipers; Thus, it really possesses double effect in economic benefit and environmental protection.
