Abstract

A windshield wiper blade device is constructed and formed to be releasably secured in a fitted engagement upon an existing wiper arm and blade assembly to provide an effective wiping blade that is easily installed and replaceable in an integral form. The present device comprises a wiper jacket constructed in an envelope-like form partially sealed along its top edge and open but sealable along the remainder of the edge to allow the insertion of an existing wiper blade assembly within the walls of the jacket. A bladed edge having a multi-channel configuration is provided externally along the bottom of the jacket while the interior length of its chamber is formed to provide an angled nesting area for the foot of the wiper blade assembly inserted within the jacket. The chamber walls of the wiper jacket are lined with a resilient foam material on opposite sides to engage the existing blade assembly transversely and secure its position within the wiper jacket. The open top edge of the wiper jacket is provided with fastening material on opposed surfaces and a plurality of releasable straps to selectively close the open edge in a sealed engagement.

Claims

1. A device for replacing an existing wiper blade assembly having a wiper blade supported upon a frame structure and operatively connected to a wiper arm along a windshield of a vehicle, comprising:

a wiper jacket constructed having a bladed edge integrally formed along a bottom of said jacket and a chamber opened along a top edge thereof formed to contain the existing wiper blade assembly, the chamber being further formed having opposed side walls and an angled nesting area along a bottom of the chamber to support the existing wiper blade in fitted engagement;

a resilient surface layer disposed along each of the opposed side walls of the chamber of said wiper jacket, each of said surface layers being formed with a common inward profile having a continuous rounded configuration from top to bottom of the chamber to engage the existing wiper blade assembly transversely therebetween; and

fastener means operatively connected to said wiper jacket for closing the chamber in sealed engagement about the existing wiper blade assembly.

2. A device according to claim 1, wherein said wiper jacket is further constructed having a closed portion along the top edge of said jacket and a pair of flaps extending from one side wall and adapted to fold over the open chamber.

3. A device according to claim 2, wherein said fastener means comprises:

a corresponding set of hook-and-loop fastener members respectively attached to inner surfaces of said flaps and an outer surface of the side wall opposite thereto.

4. A device according to claim 3, wherein said fastener means further comprises:

at least one strap member secured to an outer surface of said flaps and adapted to wrap about said flap when folded over the open chamber; and

means for securing said strap member wrapped about said folded flap to seal the open chamber.

5. A device according to claim 4, wherein said securing means comprises:

a corresponding set of hook-and-loop fastener members respectively attached to said strap member and the outer surface of the side wall opposite thereto.

6. A device according to claim 2, wherein the bladed edge is formed having a multi-channel configuration with a plurality of wiping elements along the edge.

7. A device according to claim 1, wherein each of said resilient surface layers are separated in the chamber and disposed facing each other in a symmetrical arrangement to engage the frame structure of the existing wiper blade assembly transversely with clamping pressure evenly applied thereto.

8. A windshield wiper blade device for replacing an existing wiper blade assembly of a type having a wiper blade supported upon a frame structure and operatively connected to a wiper arm, comprising:

a jacket member constructed having a bladed edge integrally formed along a bottom of said jacket member and a chamber partially opened along a top edge thereof formed to contain the existing wiper blade assembly, the chamber being further formed having opposed side walls each lined with a resilient surface layer having a common inward profile with a continuous rounded configuration from top to bottom of the chamber to engage the existing wiper blade assembly transversely therebetween and an angled nesting area along a bottom of the chamber to hold the existing wiper blade therein; and

fastener means operatively connected to said jacket member for closing the chamber in sealed engagement about the existing wiper blade assembly.

9. A windshield wiper blade device according to claim 8, wherein said jacket member is further constructed having at least one flap extending from one of the opposed side walls and adapted to fold over the open top edge of the chamber.

10. A windshield wiper blade device according to claim 9, wherein said fastener means comprises:

a corresponding set of hook-and-loop fastener members respectively attached to inner surfaces of said flaps and an outer surface of the side wall opposite thereto.

11. A windshield wiper blade device according to claim 10, wherein said fastener means further comprises:

at least one strap member secured to an outer surface of said flaps and adapted to wrap about said flap when folded over the open chamber; and

means for securing said strap member wrapped about said folded flap to seal the open chamber.

12. A windshield wiper blade device according to claim 11, wherein said securing means comprises:

a corresponding set of hook-and-loop fastener members respectively attached to said strap member and the outer surface of the side wall opposite thereto.

13. A windshield wiper blade device according to claim 8, wherein the bladed edge of said jacket member is formed having a multi-channel configuration with a plurality of wiping elements along the edge.

14. In an automatic windshield wiper system having an existing wiper blade held upon associated frame structure operatively mounted to a wiper arm along a windshield of a vehicle, an improved device for wiper blade replacement comprising:

bladed jacket means for fitted containment of the wiper blade and associated frame structure in operative engagement with the wiper arm, said bladed jacket means comprising a wiper jacket constructed having a bladed edge integrally formed along a bottom of said jacket and a chamber opened along a top edge thereof formed to contain the existing wiper blade and associated frame structure, the chamber being further formed having opposed side walls and an angled nesting area along a bottom of the chamber to support the existing wiper blade in fitted engagement, and a resilient surface layer disposed along each of the opposed side walls of the chamber from top to bottom thereof, each of said surface layers being formed with a common inward profile having a continuous rounded configuration to engage the associated frame structure transversely therebetween; and

fastener means for releasably sealing said bladed jacket means about the wiper blade and associated frame structure.

15. The improved wiper blade replacement device of claim 14, wherein the bladed edge is formed having a multi-channel configuration with a plurality of wiping elements along the edge.

16. The improved wiper blade replacement device of claim 14, wherein each of said resilient surface layers are separated in the chamber and disposed facing each other in a symmetrical arrangement to engage the frame structure of the existing wiper blade assembly transversely with clamping pressure evenly applied thereto.

17. The improved wiper blade replacement device of claim 14, wherein said wiper jacket is further constructed having a closed portion along the top edge of said jacket and a pair of flaps extending from one side wall and adapted to fold over the open chamber.

18. The improved wiper blade replacement device of claim 17, wherein said fastener means comprises:

a corresponding set of hook-and-loop fastener members respectively attached to inner surfaces of said flaps and an outer surface of the side wall opposite thereto.

19. The improved wiper blade replacement device of claim 18, wherein said fastener means further comprises:

at least one strap member secured to an outer surface of said flaps and adapted to wrap about said flap when folded over the open chamber; and

means for securing said strap member wrapped about said folded flap to seal the open chamber.
