Intermittent wiper cleaning system

An intermittent wiper cleaning system for removing debris and other foreign matter from a wiper for a surface such as a windshield serviced by a wiper, said system comprising a plurality of discrete raised elements projecting from said surface, said elements being formed as circular projections adhesively attached to the surface serviced by said wiper, said elements being arranged in horizontally extending rows that are vertically spaced, said rows extending for a distance corresponding to the length of the wiper, said elements being arranged in parallel horizontal alignment in each row and in generally vertical alignment in alternate rows and in staggered alignment in adjacent rows, said elements being spaced from each other by a distance such that debris and other foreign matter removed from the wiper by the system can be channeled therebetween.

An intermittent wiper cleaning system for removing debris from the surface of a wiper of a windshield comprising a generally planar base member having an upper surface, a lower surface, and side surfaces, said lower surface of said base member having adhesive means thereon for attachment to said windshield, said upper surface having a plurality of elongated scraping projections extending therefrom adapted to remove debris from the surface of the wiper, said elongated projections having rounded ends and being arranged in at least two groups, one of said groups having a series of generally parallel elongated projections and the other of said groups also having a series of generally parallel elongated projections, said projections of said one group being spaced from and arranged generally perpendicular to said projections of said other group so as to provide passageways for drainage.

A windshield having a front and back surfaces, said front surface having an upper and lower region, said lower region of said front surface having means for removing debris from the surface of a wiper servicing said windshield, said means including a plurality of elongated scraping projections extending outwardly from said front surface and having rounded ends, said elongated projections being arranged in at least two groups, one of said groups having a series of generally parallel elongated projections and the other of said groups also having a series of generally parallel elongated projections, said projections of said one group being spaced from and arranged generally perpendicular to said projections of said other group so as to provide passage for drainage.

An intermittent wiper cleaning system for removing debris from the surface of a wiper of a windshield comprising a generally planar base member having an upper surface, a lower surface, and side surfaces, said lower surface of said base member having adhesive means thereon for attachment to said windshield, and a plurality of elongated scraping depressions formed in said base member and adapted to remove debris from the surface of the wiper, said elongated depressions having rounded ends and being arranged in at least two groups, one of said groups having a series of generally parallel elongated depressions and the other of aid groups also having a series of generally parallel elongated depressions, said depressions of one said one group being spaced from and arranged generally perpendicular to said depressions of said other group so as to provide passageways for drainage.
