Abstract
A windshield wiper blade cleaning device is disclosed having a channel for receiving the tip of a wiper blade, the channel having a frictional base for removing dirt from the tip of the blade as the blade is drawn longitudinally through the channel. In an alternate embodiment, the channel also has frictional walls for cleaning the sides of the blade. In described embodiment, the base and/or walls are made frictional by means of projections, filaments, or abrasive materials.
Claims15
A wiper blade cleaning device comprising:
- a base element;
- two walls attached orthogonally to said base element in facing relationship, thus defining a channel of a certain width between said facing walls for engagement with a wiper blade, said channel having dimensions suitable for receiving at least a portion of an edge of said wiper blade, each said wall in facing relationship consisting of a first portion adjacent and orthogonal to said base element and a second portion remote from and non-orthogonal to said base element, said second wall portions directed away frown each other in a substantially V-shaped cross-section, said V-shaped cross-section having a width greater than any width between said first wall portions but not greater than the width of said base element;
- and
- friction means on at least a portion of the base element, said friction means comprising a plurality of projections disposed within said channel,
- whereby when said channel is engaged with a wiper blade and said device and wiper blade are moved relative to each other, said friction means produces a wiping action on the edge of said wiper blade, thereby cleaning without eroding said wiper blade.

- and
- friction means on at least a portion of said base element, said friction means comprising a plurality of filaments attached to said base element and extending substantially orthogonal to said base element and into said channel, thereby forming a brush on the base of said channel;
- whereby when said channel is engaged with a wiper blade and said device and wiper blade are moved relative to each other, said friction means produces a wiping action on the sides of said wiper blade, thereby cleaning without eroding said wiper blade.

- and
- friction means on at least pan of at least one said wall, said friction means comprising a plurality of projections disposed along said part of said wall and extending into said channel,
- said device being arranged and constructed such that when said channel is engaged with a wiper blade and said device and wiper blade are moved relative to each other, said friction means produces a wiping action on the edge of said wiper blade, thereby cleaning without eroding said wiper blade.

A wiper blade cleaning device comprising:
- a base element;
- two walls attached orthogonally to said base element in facing relationship, each said wall consisting of a first portion adjacent and orthogonal to said base element and a second portion remote from and non-orthogonal to said base element, said first portions being substantially parallel to one another and defining a channel having a cross-sectional dimension suitable for receiving at least a portion of an edge of said wiper blade, said second portions diverging from each other such that all cross-sectional dimensions defined by said second portions are greater than said cross-sectional dimension of said channel;
- and
- friction means on at least a portion of the base element, said friction means comprising a plurality of projections disposed within said channel,
- whereby when said channel of said device is engaged with a wiper blade and said device and wiper blade are moved relative to each other, said friction means produces a wiping action on the edge of said wiper blade, thereby cleaning without eroding said wiper blade.
