Wiper blade with modular mounting base
View Patent ↗A wiper blade with a modular mounting base, having a wiper strip and a primary frame. The primary frame may be provided with a recessed portion having a base portion, a proximal end and a distal end, and may further be provided with a projection disposed on the proximal end, and with receiving holes on the base portion. The primary frame is capable of securing a mounting base having a bottom, a proximal end and a distal end such that one or more locking legs descending from the bottom of the mounting base can engage the receiving holes in the bottom portion of the primary frame, and such that the projection on the proximal portion of the recessed portion engages a guiding channel on the proximal end of the mounting base.
1. A wiper blade comprising:
a wiper strip;
a primary frame coupled to at least one secondary frame, the primary frame having a recessed portion, wherein the recessed portion has a base portion, a proximal end and a distal end, a projection is disposed on the proximal end of the recessed portion, and at least one receiving hole is disposed in the base portion of the recessed portion; and
a mounting base having bottom, a proximal end and a distal end, wherein at least one locking leg descends from the bottom of the mounting base such that the at least one receiving hole in the base portion of the recessed portion of the primary frame is capable of receiving the at least one locking leg when the mounting base is attached to the primary frame, wherein the at least one locking leg each comprises a bottom edge comprising locking tabs extending laterally from the bottom edge, and
wherein the proximal end comprises two retaining projections and a guiding channel therebetween, wherein the guiding channel is capable of receiving the projection from the primary frame such that the retaining projections sit on either side of the projection on the primary frame when the mounting base is attached to the primary frame.
2. The wiper blade of claim 1 , wherein the retaining projections are chamfered.
3. The wiper blade of claim 1 wherein the primary frame further comprises at least one locking recess on the distal end of the recessed portion of the primary frame, and the mounting base has at least one locking projection on the distal end of the mounting base which is capable of engaging the at least one locking recess when the mounting base is attached to the primary frame.
4. The wiper blade of claim 1 wherein the primary frame further comprises a distal cutout disposed on the distal end of the recessed portion.
5. The wiper blade of claim 1 , wherein the mounting base further comprises inner and outer side walls, wherein the mounting base has a connecting structure that is capable of connecting to a wiper arm selected from the group consisting of: a rivet extending between the inner side walls, at least one interior projection extending from the inner side walls, a rivet extending between the inner side walls and at least one interior projection extending from the inner side walls, at least one peg extending from the inner side walls, at least one recess in the inner side walls, at least one hole in the inner side walls and at least one detent in the inner side walls.
6. The wiper blade of claim 1 , wherein the mounting base further comprises outer side walls wherein the mounting base has a connecting structure that is capable of connecting to a wiper arm selected from the group consisting of: at least one outer projection extending from the outer side walls, at least one peg extending from the outer side walls, at least one recess in the outer side walls, at least one hole in the outer side walls and at least one detent in the outer side walls.
