Windscreen wiper device
View Patent ↗A windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade ( 2 ) of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes opposing longitudinal grooves on its longitudinal sides, in which grooves spaced-apart longitudinal strips ( 4 ) of the carrier element are disposed, wherein neighboring ends of said longitudinal strips are interconnected by a respective connecting piece (G), which windscreen wiper device comprises a connecting device ( 7 ) for an oscillating wiper arm ( 8 ), with the special feature that said wiper blade is detachably connected to said longitudinal strips, wherein said wiper blade can freely slide along said longitudinal strips between a first position, wherein said wiper blade is retained onto said longitudinal strips, and a second position, wherein said wiper blade is disconnected from said longitudinal strips in order to be replaced or repaired.
1. A windscreen wiper device comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes opposing longitudinal grooves on its longitudinal sides, in which grooves spaced-apart longitudinal strips of the carrier element are disposed, wherein neighboring ends of said longitudinal strips are interconnected by a respective connecting piece constructed as a separate component from said carrier element, which windscreen wiper device comprises a connecting device for an oscillating wiper arm, wherein said wiper blade is detachably connected to said longitudinal strips, wherein at least one of said longitudinal strips comprises a recess at the location of its interior longitudinal edge, and wherein said wiper blade can be slidably connected to or disconnected from said longitudinal strips through said recess wherein said wiper blade can freely slide along said longitudinal strips between a first position, wherein said wiper blade is retained onto said longitudinal strips, and a second position, wherein said wiper blade is disconnected from said longitudinal strips in order to be replaced or repaired, and wherein said connecting pieces and said strips are slidably connected by a snap connection in a way that supports and maintains the strips sufficiently apart so that the wiper blade can slide longitudinally relative to the strips, and said connecting pieces are provided with a stop surface in order to block a relative movement of the wiper blade along the strips inside said connecting pieces during use, said stop surface forming an end wall of said connecting pieces.
2. A windscreen wiper device according to claim 1 , wherein said recesses of said longitudinal strips form an aperture, and wherein said wiper blade can be slidably connected to or disconnected from said longitudinal strips through said aperture.
3. A windscreen wiper device according to claim 1 , wherein at least one connecting piece comprises engaging members engaging around said longitudinal strips so that said longitudinal strips are mounted in grooves formed by said engaging members, and wherein in the first position of said wiper blade a free end of said wiper blade is adjacent to said stop surface of said connecting piece.
4. A windscreen wiper device according to claim 3 , wherein the snap connection comprises laterally extending means on said longitudinal strips.
5. A windscreen wiper device according to claim 4 , wherein said laterally extending means comprise at least one protrusion extending laterally from a longitudinal edge of each longitudinal strip, said protrusion being located between stops on said connecting piece.
6. A windscreen wiper device according to claim 4 , wherein said laterally extending means comprise at least two stops extending laterally from a longitudinal edge of each longitudinal strip, said stops being located on opposite sides of a protrusion on said connecting piece.
7. A windscreen wiper device according to claim 4 , wherein said laterally extending means extend laterally from the interior longitudinal edge of each longitudinal strip.
8. A windscreen wiper device according to claim 3 , wherein said engaging members are integral with said connecting piece.
9. A windscreen wiper device according to claim 1 , wherein a spoiler is provided, and wherein said spoiler is retained onto said longitudinal strips.
10. A windscreen wiper device according to claim 9 , wherein said spoiler comprises engaging members engaging around the longitudinal strips so that said strips are mounted in grooves formed by said engaging members.
11. A windscreen wiper device according to claim 10 , wherein the engaging members of said spoiler are integral with said spoiler.
12. A windscreen wiper device according to claim 1 , wherein said connecting device comprises engaging members engaging around the longitudinal strips so that said strips are mounted in grooves formed by said engaging members.
13. A windscreen wiper device according to claim 12 , wherein said engaging members of said connecting device are integral with said connecting device.
