Abstract

For any windscreen wiper comprising: a/ a lever inserted between its pointof attachment of its base supporting the blade rod and a hinge allowing thislever to be connected to the end piece of the pin providing lateral movement.b/ a second pin, having a rotary movement, housed in a central recess of themain pin and comprising at its outer end one (or more) cams able to lift theinserted lever at each contact. c/ a spring acting in the opposite way.

  Mécanisme pour essuie-glace à double action. 



  Principe : nous entendons par double action, un essuie-glace dont le mouvement latéral est doublé d'un mouvement longitudinal alternatif. 



  Description : considérons le balai d'un essuie-glace sa tige et sa base comportant sa charnière et son ressort habituels. 



  Fixons cette base non plus sur l'axe principal, mais à l'extrémité d'un levier intercalaire, dont l'autre extrémité sera reliée par une charnière à l'embout de l'axe principal. Cette charnière avec deux pivots diamétralement opposés fixés sur l'extrémité de cet axe permettra à la partie opposée du levier, lié à la base de s'élever et de s'abaisser dans un plan longitudinal. 



  Ces oscillations seront dues : a/à la (ou les) came fixée à l'embout extérieur d'un second axe, soumis à un mouvement rotatif, qui sera logé dans un évidement central réalisé dans l'axe principal. 



  A chaque rotation la came par contact soulévera le levier intercalaire. 



  Un ressort assurera le mouvement contraire.

  Double action wiper mechanism.



  Principle: we mean by double action, a wiper whose lateral movement is doubled by an alternative longitudinal movement.



  Description: let us consider the wiper blade with its rod and its base comprising its usual hinge and spring.



  Let's fix this base no longer on the main axis, but at the end of an intermediate lever, the other end of which will be connected by a hinge to the end piece of the main axis. This hinge with two diametrically opposite pivots fixed on the end of this axis will allow the opposite part of the lever, linked to the base to rise and fall in a longitudinal plane.



  These oscillations will be due to: a / the cam (s) fixed to the outer end of a second axis, subjected to a rotary movement, which will be housed in a central recess made in the main axis.



  At each rotation, the contact cam will raise the intermediate lever.



  A spring will ensure the opposite movement.

Claims

Claim.

Double action wiper mechanism.

For any double action wiper, made: 10 / with the base of the rod, no longer fixed as always to the axis ensuring the reciprocating movement but at the end of an intermediate lever, the other end of which will be attached to the end piece of the aforementioned axis, by a hinge, arranged so as to allow the end linked to the base to be able to raise and lower in a longitudinal plane.

20 / and also to include, housed in a central recess made in the main axis, a second axis, subjected to a rotary movement, provided at its outer end with a (or more) cam whose contact by rotation will raise the lever interlayer integral with the base of the wiper.

) / a return spring, ensuring the opposite oscillation.
