Definitions

  • the present invention concerns automobile windscreen wiper blades and, more specifically, the articulated gear connecting the wiper blade support frame to the swing-arm, the latter being traditional in form and mode of operation.
  • Another device also proposed many years ago, consists in fabricating the support frame proper in some elastic material consolidated to the metal spring-plate in virtually the same way as in the first design.
  • the present invention is based on a brand new concept according to which the main coupling piece and the spring-plate are made of two totally different plastic materials, the first being relatively hard and stress resistant while the other is fairly supple and elastic.
  • the concept is peculiar and innovative in that the curled U-shaped hand of the swing-arm is locked safely into the coupling gear by the action of the elastic component which incorporates a backstop forbidding untimely disconnection of the gear.
  • FIG. 1 represents a longitudinal section of the invented coupling gear
  • FIG. 2 represents a horizontal section along line ll-II of FIG. 1;
  • FIG. 3 is an enlarged view of a cross-section taken at level Ill-III of FIG. 1;
  • FIG. 4 is a lateral view of the rigid component of the coupling gear
  • FIG. 5 is the horizontal projection of this rigid component
  • FIGS. 6 and 7 are sections taken respectively along lines Vl-VI and VII-VII of FIG. 5;
  • FIG. 8 is a lateral view of the flexible component
  • FIG. 9 is the horizontal projection of this component
  • FIGS. 10 and 11 are sections of the flexible component taken along lines X-X and Xl-Xl, respectively, of FIG. 9;
  • FIG. 12 like FIG. 1, illustrates the coupling gear but during disconnection
  • FIG. 13 is similar to FIG. 1 but represents an alternative design
  • FIGS. 14 and 15 represent sections along lines XIV-XIV and XVXV, respectively, of the representation of FIG. 13;
  • FIG. 16 is a lateral view of the stiff component
  • FIG. 17 is a horizontal projection of the same component
  • FIGS. 18 and 19 represent sections taken respectively along lines XVIII-XVIII and XIX-XIX of FIG.
  • FIG. 20 is a side-view of the flexible component
  • FIG. 21 is a horizontal projection of this component
  • FIGS. 22 and 23 are sections taken along lines XXII- XXII and XXIII-XXIII, respectively, of FIG. 21;
  • FIG. 24 is similar to FIG. 13 but shows the device in its position during disconnection.
  • 1 is the articulated coupling gear as described herein; 2 the central segment of the main bridge of the wiper blade support frame; 3 the pivot or axis around which the coupling gear is articulated and by which it is fixed to the support frame; 4 the swingarm having a generally U-shaped end; S the component made of a relatively stiff plastic material; 6 the component made of a relatively elastic plastic material.
  • the stiff component consists of a hollow casing 7 having a near U or C- shaped vertical longitudinal channel-shaped section which expands into a central lobe 8, flanked on either side by two shoulders 9 and 10.
  • the lobe 8 is pierced by a hole 11 into which fits the pivot 3.
  • Atransverse groove 12 is cut into and below this lobe.
  • the flexible component 6, made of an elastic plastic material consists of a rod 13 having an abutment nose 14 near its foreend which acts as backstop to the curved end of the swing-arm by engaging the end surface of the reversely bent short leg of arm 4 and, towards its rear end, two small parallel cheeks 15 and 16 separated by slightly more than the thickness of the lobe 8. Both cheeks are pierced by coaxial holes 17 and 18.
  • Parts 5 and 6 are thus destined to fit into each other in such a way that pivot 3 passes through coaxial holes l1, l7 and 18, cross-bar 19 fits into groove 12 and prismatic stop-pins 20, 21 abut against the adjacent surface of the hollow casing 7 of the hard plastic component 5.
  • the distance between the backstop 14 and the rear surface of the hollow casing 7 is equal to or slightly greater than the length of the hand (curved end) of the swing-arm 4.
  • the two complementary components 5 and 6 can interlock in such a way as to bring the three holes 24, 25 and 27 into coaxial alignment with each other, allowing the introduction of pivot 3 which is riveted to the frame 2.
  • the two components 5 and 6 are similar in every way to those of the first model.
  • the flexible member 6 interengages and interlocks with the rear end of member 5 so that member 6 is not rotatable relative to member 5 about the pivot pin 3.
  • one end ofthe member 6 is essentially rigid with member 5 whereas its other end is free to flex toward and away from the back wall of member 5.
  • said other sides of said socket comprise a single generally channel shaped member and wherein said resilient side is a separate member extending freely along the open side of said channel and is fixedly and nonrotatably connected to said member at its end remote from said open end.
  • a device as defined in claim 3 wherein said single fastening means comprises a pin member serving also to pivotally connect said wiper blade to said socket means.
  • said overlapping and interlocking portions comprise a pair of spaced parallel ears on one of said channel shaped member and said separate member and a single lug on the other, positioned between said ears, said fastening means extending through aligned openings in said ears and lugs.
