Windscreen wiper device
View Patent ↗A windscreen wiper device, particularly for automobiles, includes 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 is of the flat blade type and includes at least one groove, in which groove a longitudinal strip of the carrier element is disposed. The windscreen wiper device further includes a mounting head for transferring a reciprocal movement to the wiper blade, with the special feature of a connecting device for detachably connecting the wiper blade directly to the mounting head, wherein the connecting device is positioned near one end of the wiper blade.
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 at least one groove, in which groove a longitudinal strip of the carrier element is disposed, wherein said windscreen wiper device further comprises a mounting head for transferring a reciprocal movement to said wiper blade, and a connecting device for detachably connecting said wiper blade directly to said mounting head though a bayonet connection, wherein said connecting device covers a first terminal end of said longitudinal strip and is positioned substantially adjacent to one end of said wiper blade to engage said mounting head substantially adjacent said end of said wiper blade, wherein an end cap covers a second terminal end of said longitudinal strip, wherein said connecting device and said end cap are connected to said wiper blade at opposite ends thereof, wherein said connecting device comprises at least one resilient tongue of said bayonet connection engaging in a correspondingly shaped hole of said bayonet connection provided in said mounting head, and wherein said resilient tongue is allowed to be pushed in against said spring force to allow for sliding of said connecting device away from said mounting head in order to release said wiper blade from said mounting head.
2. A windscreen wiper device according to claim 1 , wherein said longitudinal strip is biassed in such a way that its curvature near the connecting device is larger than its curvature near the other end of said wiper blade.
3. A windscreen wiper device according to claim 1 , wherein an interconnection between the mounting head and the wiper blade does not allow any pivotal movement therebetween.
4. A windscreen wiper device according to claim 1 , wherein said mounting head is fixed for rotation to a shaft, and wherein said shaft is rotatable alternately in a clockwise and in a counter-clockwise sense carrying said mounting head into rotation.
5. 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 at least one groove, in which groove a longitudinal strip of the carrier element is disposed, wherein said windscreen wiper device further comprises a mounting head for transferring a reciprocal movement to said wiper blade, and a connecting device for detachably connecting said wiper blade directly to said mounting head through a bayonet connection, wherein said connecting device is positioned substantially adjacent to one end of said wiper blade, wherein said connecting device and an end cap are connected to said wiper blade at opposite ends thereof, wherein said connecting device comprises at least one resilient tongue of said bayonet connection engaging in a correspondingly shaped hole of said bayonet connection provided in said mounting head and wherein said resilient tongue is allowed to be pushed in against a spring force to allow sliding of said connecting device away from said mounting head in order to release said wiper blade from said mounting head, wherein said mounting head has an at least substantially U-shaped cross-section at the location of its attachment to said connecting device, and wherein each leg of said U-shaped cross-section comprises clamping members formed as inwardly bend edges at the end of said legs, which engage around longitudinal sides of said connecting device that face away from each other.
6. A windscreen wiper device according to claim 5 , wherein said hole is provided in a base of a U-shaped cross-section of said mounting head.
7. 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 at least one groove, in which groove a longitudinal strip of the carrier element is disposed, and a connecting device for detachably connecting said wiper blade directly to a reciprocating mounting head through a bayonet connection, wherein said connecting device is coupled to said carrier element and covers a first terminal end of said longitudinal strip to engage said mounting head adjacent said end of said wiper blade, wherein an end cap covers a second terminal end of said longitudinal strip, wherein said connecting device and an end cap are disposed at opposite ends of said wiper blade, wherein said connecting device comprises at least one resilient tongue of said bayonet connection engaging in a correspondingly shaped hole of said bayonet connection provided in said mounting head, and wherein said resilient tongue is allowed to be pushed in against a spring force to allow sliding of said connecting device away from the mounting head in order to release said wiper blade from the mounting head.
