Windscreen wiper device
The windscreen wiper device includes a wiper element and a least one carrier element. The wiper device also includes a connecting device, which includes a base and a joint part. The joint part has a top wall that extends in a lateral direction between a pair of side walls. The joint part also has a button configuration for lockingly attaching the connecting device with at least two different types of oscillating wiper arms. The button configuration includes first and second buttons, each of which is attached with the side walls via resilient strips. The resilient strips extend directly from the side walls to the buttons. The resilient strips bias the buttons into raised positions wherein the buttons project above the top walls. The resilient strips also allow the buttons to move to a pressed position wherein a top surface of the respective button is generally flush with the top wall.
1. A windscreen wiper device, comprising:
a wiper element made of an elastomeric material;
at least one carrier element operably supporting said wiper element;
a connecting device including a base that is fixedly attached with said at least one carrier element and including a joint part that is attached with said base such that said joint part can pivot about a pivot axis;
said joint part having a top wall that extends in a lateral direction between a pair of side walls;
said joint part including a button configuration for lockingly attaching said connecting device with at least two different types of oscillating wiper arms;
said button configuration including a first button and a second button; and
each of said first and second buttons being attached with said side walls via resilient strips, each resilient strip extending directly from one of said side walls at a location which is spaced vertically below said top wall to one of said first and second buttons, said resilient strips biasing said first and second buttons into raised positions wherein said first and second buttons project above said top wall, and said resilient strips allowing said first and second buttons to move to a pressed button position wherein a top surface of said first or second button is generally flush with said top wall.
2. The windscreen wiper device as set forth in claim 1 further including two resilient strips which are connected with said first button and two resilient strips which are connected with said second button.
3. The windscreen wiper device as set forth in claim 1 wherein each of said resilient strips is generally L-shaped with a short leg that is directly connected with one of said side walls and a long leg that is directly connected with one of said first and second buttons.
4. The windscreen wiper device as set forth in claim 1 wherein said first and second buttons are spaced from one another in a longitudinal direction.
5. The windscreen wiper device as set forth in claim 1 wherein each of said first and second buttons has a ramped surface which faces in a longitudinal direction away from said pivot axis.
6. The windscreen wiper device as set forth in claim 1 wherein said top wall of said joint part has a window and wherein said first and second buttons are located in said window.
7. The windscreen wiper device as set forth in claim 1 wherein said joint part includes a main body portion and a front nose portion that is positioned at one longitudinal end of said main body portion.
8. The windscreen wiper device as set forth in claim 7 wherein said front nose portion has a tongue which overlies said top wall.
9. The windscreen wiper device as set forth in claim 7 wherein said front nose portion has a greater width and a greater height than said main body portion.
10. The windscreen wiper device as set forth in claim 1 wherein said joint part includes spring fingers that protrude laterally outwardly from said side walls.
11. The windscreen wiper device as set forth in claim 1 wherein said base includes a pair of laterally outwardly extending and co-axially aligned protrusions and wherein said side walls of said joint part include a pair of circular openings which receive said protrusions to connect said joint part with said base.
12. The windscreen wiper device as set forth in claim 11 wherein said first and second buttons are located in a longitudinal direction closer to one longitudinal end of said joint part than to said circular openings.
