Windscreen wiper device
A windscreen wiper device includes an elongated wiper blade, a spoiler, and a connector assembly. The spoiler is coupled to and extends between opposite ends along the longitudinal length of the wiper blade. The connector assembly is operably attached to the spoiler and detachably connects the windscreen wiper device to an oscillating wiper arm adapted to oscillate the wiper blade along the surface of a curved windshield of a vehicle.
1. A windscreen wiper device including;
an elongated wiper blade,
a spoiler coupled to and extending between opposite ends along the longitudinal length of the wiper blade, wherein the spoiler includes a raised upper wall and a pair of arms that are recessed below and located on opposite lateral sides of the upper wall, wherein the arms of the spoiler are shaped to wrap around a pair of opposite lateral edges of the wiper blade, the lateral edges being parallel in relation to one another, and wherein the upper wall of the spoiler has a pair of through holes, the through holes being located in a central location of the spoiler, and
a connector assembly being operably attached to the spoiler approximately at a longitudinal midpoint of the windscreen wiper device and detachably connecting the windscreen wiper device to an oscillating wiper arm adapted to oscillate the wiper blade along the surface of a curved windshield of a vehicle.
2. The windscreen wiper device of claim 1 , wherein the spoiler is retained on a carrier element, the carrier element extending across and operably supporting the wiper blade, the carrier element biasing the wiper blade into a curved configuration to seal its full length against the curved windshield of the vehicle.
3. The windscreen wiper device of claim 2 , wherein the spoiler is made of a single piece of flexible plastic material allowing it to flex with the wiper blade on the curved windshield.
4. The windscreen wiper device of claim 3 , wherein a pair of endcaps is included, the endcaps being fixedly attached on the opposite ends of the spoiler connecting the wiper blade to the spoiler.
5. The windscreen wiper device of claim 1 , wherein the through holes are disposed adjacent to one another on opposite sides of a mid-plane of the spoiler, and are circular in shape.
6. The windscreen wiper device of claim 5 , wherein the connector assembly includes a base portion and a joint portion.
7. The windscreen wiper device of claim 6 , wherein the joint portion is shaped to directly engage with the oscillating wiper arm.
8. The windscreen wiper device of claim 7 , wherein the base portion is configured to operably connect the joint portion with the remainder of the windscreen wiper device.
9. The windscreen wiper device of claim 8 , wherein the base portion includes a pair of arms extending from a pair of side walls, the side walls being spaced apart from one another in the lateral direction, the arms wrapping around the spoiler to retain a connection between the base portion and the spoiler.
10. The windscreen wiper device of claim 9 , wherein the base includes a pair of projections, the projections being circular in shape and extending in opposite lateral direction.
11. The windscreen wiper device of claim 10 , wherein the joint portion includes a pair of side walls which are spaced apart from one another in the lateral direction, the side walls further including a pair of openings that are shaped to receive the projections of the base to allow the joint portion to pivot in relation to the base portion about a pivot axis.
12. The windscreen wiper device of claim 11 , wherein the base portion includes a floor which extends laterally between the arms, the floor portion overlying the upper wall of the spoiler when the windscreen wiper device is fully assembled.
13. The windscreen wiper device of claim 12 , wherein the floor of the base portion includes a rectangularly shaped primary window, the primary window allowing an installer to view the base portion for proper alignment during installation.
14. The windscreen wiper device of claim 13 , wherein the base portion includes a pair of protrusions, the protrusions extending downwardly from the floor and are disposed on opposite longitudinal sides of the primary window, the protrusions being spaced apart from one another by the same distance as the through holes of the spoiler so as to be received within the through holes when the windscreen wiper device is fully assembled.
15. The windscreen wiper device of claim 14 , wherein the protrusions of the base portion include a curved portion and a linear portion, the curved portion being a similar diameter to the through holes of the spoiler and facing longitudinally away from one another, the linear portions being generally flush with an inner edge of the floor of the base portion and facing longitudinally towards one another.
16. The windscreen wiper device of claim 15 , wherein a pair of secondary windows is included, the secondary windows being rectangular in shape and smaller in area than the primary window, the secondary windows being on opposite lateral sides of the respective protrusion.
