Windscreen wiper device
A connecting device ( 6 ) is provided for interconnecting a windscreen wiper device ( 1 ) of the flat blade type and an oscillating arm ( 7 ) pivotally connectable to the connecting device about a pivot axis near one end thereof. The windscreen wiper device includes 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. The wiper blade includes at least one groove ( 3 ), in which groove a longitudinal strip ( 4 ) of the carrier element is disposed. The connecting device is arranged to be connected to the longitudinal strip, and includes—at least one hole ( 19 ) of a first type arranged to allow a welding tool access through the hole of the first type to contact the longitudinal strip for welding the longitudinal strip and the connecting device together; and—at least one hole ( 20 ) of a second type arranged to allow a pin access through the hole of the second type and through the longitudinal strip for interconnecting the longitudinal strip and the connecting device.
1. A windscreen wiper device comprising an elastic, elongated carrier element and an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, which wiper blade includes at least one groove, in which at least one groove a longitudinal strip of said carrier element is disposed, said windscreen wiper device further comprising:
a connecting device for interconnecting said windscreen wiper device and an oscillating arm pivotally connectable to said connecting device about a pivot axis near one end thereof, wherein said connecting device includes two pairs of blind holes and two pairs of through holes, wherein each pair of blind holes aligns with each pair of through holes along a longitudinal axis of said connecting device, and wherein said pair of through holes is separated by said pair of blind holes, wherein each blind hole is arranged to allow a welding tool access through said blind hole to contact said longitudinal strip for welding said longitudinal strip and said connecting device together, wherein each through hole is open from a bottom of said connecting device, wherein said connecting device has a U-shaped cross section with free ends of legs of said U-shaped cross section extending inwardly so that one of said free ends receives a longitudinal side of said longitudinal strip; and
four pins, wherein each pin cooperates with one of said through holes and a corresponding hole in said longitudinal strip, wherein each pin interconnects said longitudinal strip and said connecting device to block longitudinal movement of said connecting device relative to said longitudinal strip.
2. The windscreen wiper device according to claim 1 , wherein each pair of blind holes comprises opposing blind holes, wherein each pair of blind holes is located near an end wall of said connecting device.
3. The windscreen wiper device according to claim 1 , wherein each pair of through holes comprises opposing through holes, wherein each pair of through holes is located near an end wall of said connecting device.
4. The windscreen wiper device according to claim 1 , wherein each of said blind holes is open from a top of said connecting device.
5. A windscreen wiper device comprising:
an elastic, elongated carrier element;
an elongated wiper blade of a flexible material, which can be placed in abutment with a windscreen to be wiped, wherein said wiper blade includes at least one groove in which a longitudinal strip of said carrier element is disposed;
a connecting device comprising:
two pairs of blind holes, wherein a portion of each of said blind holes is welded to said longitudinal strip; and
two pairs of through holes open from a bottom of said connecting device,
wherein each pair of blind holes aligns with each pair of through holes along a longitudinal axis of said connecting device, and wherein said pair of through holes is separated by said pair of blind holes; and
four pins, wherein each pin cooperates with one of said through holes and a corresponding hole in said longitudinal strip, wherein each pin interconnects said longitudinal strip and said connecting device to block longitudinal movement of said connecting device relative to said longitudinal strip.
6. The windscreen wiper device according to claim 5 , wherein said connecting device comprises engaging members made integral therewith arranged to engage around longitudinal sides of said longitudinal strip disposed in opposing grooves of said wiper blade.
7. The windscreen wiper device according to claim 5 , wherein each pair of blind holes comprises opposing blind holes, wherein each pair of blind holes is located near an end wall of said connecting device.
8. The windscreen wiper device according to claim 5 , wherein each pair of through holes comprises opposing through holes, wherein each pair of through holes is located near an end wall of said connecting device.
9. The windscreen wiper device according to claim 5 , wherein each of said blind holes is open from a top of said connecting device.
