WINDSHIELD WIPER STRUCTURE FOR VEHICLES
First Claim
1. A windshield wiper structure for vehicles, comprising a truss saddle, a bow elastic stripe, a cover body, a plurality of detachable clamping devices, a strip scraper, and a frame cover;
- wherein said truss saddle is fixed on one end of the wiper arm by means of a wiper connector;
wherein the bow elastic stripe is made of metal, has a bow shape, bends downward, and is tightly affixed to a bottom surface on a bottom side of said truss saddle and abutting a central tope surface of said bow elastic stripe;
wherein said bow elastic stripe has a plurality of polygon holes punched into its body equidistantly, and has a plurality of hollow pressure adjusting vents between said polygon holes which have an aperture size determined in coordination with even pressure distribution;
wherein said cover body is unitarily-molded of a flexible elastic material, and Is provided at the center with a hollow opening which has an aperture size bigger than said truss saddle but smaller than said frame cover;
wherein the upper portion of said cover body is formed of an upward tapered shape, a middle portion of said cover body has a pair of strip fluted grooves with a dovetail shape which holds both sides of said blow elastic stripe, and a bottom portion of said cover body has a pari of weather-stripping fasciae downwardly extending at both sides in connection with said strip fluted grooves;
wherein each of said plurality of detachable clamping devices has a polygonal protruding ring protruded at a top end of the respective clamping device for fitting into the polygon hole of said bow elastic stripe, and has a pair of jaw-like paws protruded at a bottom end thereof for clamping said strip scraper;
wherein said strip scraper is made unitarily-molded of flexible plastic material, and has a pair of strip fluted grooves which are concave at both sides of an upper portion of the strip scraper for insertion into the jaw-like paws of the detachable clamping device, said strip fluted groove further provided with two metal elastic splint rods and a scraper edge in connection with said both sides and a lower portion of said strip scraper respectively; and
wherein said frame cover serves as sheath to accommodate said truss saddle and is provided at the center with a rectangular hole, and at a central bottom of both sides of the frame cover with two respective snap-on noses.

Abstract
A windshield wiper structure for vehicles, comprises a truss saddle, a bow elastic stripe, a cover body, some detachable clamping devices, a strip scraper and a frame cover; wherein, some hollow pressure adjusting vents are created on said bow elastic stripe in order to keep nearly same elasticity at every sections of said bow elastic stripe. Hence, it can equilibrate force in every portions of whole wiper such that achieving in adjust-effect of even pressure distribution. Then, the contact between said strip scraper and the windshield glass is holistically even tight uniformly and hermetic closely to enhance the scraping effect of windshield wiper as well as the effect of prolonging service-lifetime with reducing expense in association with decreasing of replacing new product frequency in consequence of such even pressure distribution. Thus, it has more effect in economy and environmental protection.
