Vehicle provided with at least two windscreen wiper devices
View Patent ↗A vehicle provided with at least two windscreen wiper devices each 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 of the vehicle to be wiped, each wiper blade including opposing longitudinal grooves on its longitudinal sides, in which grooves spaced-apart longitudinal strips of the carrier element are disposed, wherein neighboring ends of longitudinal strips are interconnected by a respective connecting piece, which windscreen wiper devices each comprise a connecting device for a respective oscillating arm, with the interposition of a joint part, with the special feature that each joint part and its corresponding oscillating arm comprise mutually cooperating protrusion/recess means resulting in an asymmetric form of joint part and of oscillating arm with the respect to their respective middle longitudinal planes, seen in vertical direction.
1. A vehicle provided with at least two windscreen wiper devices each 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 of the vehicle to be wiped, each wiper blade including 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, which windscreen wiper devices each comprise a connecting device for a respective oscillating arm, wherein each oscillating arm is pivotally connected to its corresponding connecting device about a pivot axis near one end, with the interposition of a joint part, wherein each joint part comprises at least one resilient tongue engaging in a correspondingly shaped hole provided in its corresponding oscillating arm, and wherein said resilient tongue is rotatable along a hinge axis between an outward position retaining a wiper blade onto its corresponding oscillating arm and an inward position releasing said wiper blade from its corresponding oscillating arm, each joint part has an at least substantially U-shaped cross-section at the location of its attachment to its corresponding connecting device, and wherein each said joint part, in at least one leg of said U-shaped cross-section, is provided with at least one laterally extending protrusion and its corresponding oscillating arm has an at least substantially U-shaped cross-section at the location of its connection to said joint part, and wherein said corresponding oscillating arm, in at least one leg of said U-shaped cross-section, is provided with at least one recess for receipt of a corresponding one of said at least one laterally extending protrusion, wherein each said at least one protrusion on each said joint part have different heights and each said at least one recess in each oscillating arm have different heights resulting in an asymmetric form of each said joint part and of each said oscillating arm with respect to their respective middle longitudinal planes, seen in vertical direction, in order to ensure that each windscreen wiper device can only be mounted on its corresponding oscillating arm.
2. Vehicle according to claim 1 , wherein each said joint part, in each leg of its U-shaped cross-section, is provided with said at least one laterally extending protrusion, and wherein said corresponding oscillating arm, in each leg of its U-shaped cross-section, is provided with said at least one recess.
3. Vehicle according to claim 1 , wherein said at least one recess has an open circumference.
4. Vehicle according to claim 1 , wherein at least one joint part is attached to its corresponding connecting device by pivotally engaging protrusions of said connecting device, at the location of said pivot axis, in recesses provided in said joint part.
5. Vehicle according to claim 1 , wherein said hole is provided in a base of said U-shaped cross-section of said oscillating arm.
6. A plurality of windscreen wiper devices for wiping separate locations of a vehicle windscreen, each of said windscreen wiper devices comprising an elastic, elongated carrier element, as well as an elongated wiper blade of a flexible material, which can be placed in abutment with the windscreen, said windscreen wiper devices each comprising a connecting device for a respective oscillating arm in the separate locations of the vehicle windscreen, wherein each oscillating arm is pivotally connected to its corresponding connecting device about a pivot axis near one end, with the interposition of a joint part, wherein each joint part comprises at least one resilient tongue for cooperation with its corresponding oscillating arm to retain the wiper blade onto its corresponding oscillating arm and being moveable to a position for releasing said wiper blade from its corresponding oscillating arm, each joint part comprising at least one protrusion and its corresponding oscillating arm comprising at least one recess, each said at least one protrusion on each said joint part having different heights and each said at least one recess in each said oscillating arm having different heights resulting in an asymmetric form of each said joint part and of each said oscillating arm with respect to their respective middle longitudinal planes, seen in vertical direction, in order to ensure that each windscreen wiper device can only be mounted on its corresponding oscillating arm.
7. A replacement windscreen wiper for replacing an existing windscreen wiper on a vehicle, said replacement windscreen wiper 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 vehicle windscreen, and a joint part configured for attachment to a connecting part of one of a plurality of oscillating arms on the vehicle, wherein the joint part comprises at least one resilient tongue to be clipped with its corresponding oscillating arm to retain said replacement windscreen wiper in attachment with its corresponding oscillating arm and being moveable to a position for releasing said replacement windscreen wiper from its corresponding oscillating arm, said joint part having a substantially U-shaped cross-section provided by a pair of legs spaced in generally parallel relation from one another with a base extending between said legs, said at least one resilient tongue movable on said joint part relative to each of said legs and said base, each of said legs having at least one protrusion extending laterally outwardly therefrom such that said at least one protrusion on one of said legs extends away from said at least one protrusion on the other of said legs, said at least one protrusion on one of said legs having a first height and said at least one protrusion on the other of said legs having a second height that is different from said first height, thereby resulting in an asymmetric form of said joint part with respect to its middle longitudinal plane, seen in vertical direction, in order to ensure that each replacement wiper can only be mounted on its corresponding oscillating arm and not another oscillating arms on the vehicle.
