Definitions

  • the present invention is directed to an improvement in a wiper blade, and particularly a wiper blade possessing a rubber body portion comprising a wiping surface portion and a reduced coefficient of friction portion.
  • Wiper blades and specifically windshield wiper blades for moving slidably across the glass windshield of an automobile or the like to remove water droplets on the surface of the glass have been the subject of development variously in order to improve the rubber base portion and/or wiping surface properties such as flexibility, weather resistance, sliding resistance, wear resistance and combinations thereof.
  • Wiper blades generally comprise an elongate generally rubber body having a base portion adapted for engagement with a harness- or beam- or any other conventional or suitable backing member for engagement of the wiper blade to a wiper arm mechanism for maintaining the wiper blade in position against the glass surface, and at least one wiping surface portion generally defining the apex and immediately surrounding area of the base portion.
  • a beam mechanism as mentioned above is disclosed in US Pat. No.
  • This deflection of the base portion causes the specific area of the wiping surface portion that is in contact with the glass surface at any given point in the operation of the wiper assembly to change, and can lead to an undesirable stick-slip phenomenon, i.e., non-constant motion or engagement of the wiping surface across the windshield, oftentimes with skipping of the blade, and concomitant non- uniform wiping action.
  • wiper blade bodies are formed of vulcanized rubber compositions comprising natural rubber (i.e., both natural- and synthetic polyisoprene) (NR), chloroprene rubber (CR), ethylene propylene copolymer (EPM) or -terpolymer (EPDM), styrene butadiene rubber (SBR), acrylonitrile butadiene rubber (NBR) or a blend of any two or more of the foregoing.
  • natural rubber i.e., both natural- and synthetic polyisoprene
  • CR chloroprene rubber
  • EPM ethylene propylene copolymer
  • EPDM -terpolymer
  • SBR styrene butadiene rubber
  • NBR acrylonitrile butadiene rubber
  • a strip comprising a vulcanized composition formed of NBR, being a base rubber other than that comprising the blade's base portion and/or wiping surface portion, and a friction reducing system comprising a combination of polytetrafluoroethylene in low but effective amounts of less than 1 part per hundred weight of rubber (phr), and minor- to equal amounts, i.e., from about 20 to about 50 phr of a plastic, i.e., polyvinyl chloride (PVC), in order to present a decreased coefficient of friction surface on either side of but spaced from the primary wiping surface or lip, optionally having irregularities formed by the plastic particles within the elastomer composition.
  • a plastic i.e., polyvinyl chloride (PVC)
  • this decreased coefficient of friction strip comprising PVC and the second base rubber contacts the windshield surface with the effect of presenting a reduced drag windshield-contacting surface. While this combination proved highly effective under most operating conditions, at ambient temperatures at or below 5°C, it was found that the lower coefficient of friction strip exhibited some stiffening, i.e., decreased flexibility, as a result of the presence of the plastic in the elastomer composition, with adverse effect on the blade's performance at such temperatures.
  • U.S. Patent No. 4,622,712 to Sugita et al teaches the incorporation of large amounts of a low particle diameter lubricant, i.e., 10 to 50 percent by volume of molybdenum disulfide or the like having particle diameter of 0.1 to 1.0 ⁇ , in the rubber forming the lip portion, i.e., the wiping surface portion, of a wiper blade.
  • a low particle diameter lubricant i.e., 10 to 50 percent by volume of molybdenum disulfide or the like having particle diameter of 0.1 to 1.0 ⁇
  • the present invention provides a wiper blade comprising an elongate generally rubber body having a base portion adapted for engagement with a backing member for maintaining the wiper blade in position; a wiping surface lip portion generally defining the apex of the base portion; and at least one strip extending along at least one side of the wiping surface lip portion and optionally spaced from the base portion apex, comprising a vulcanized composition formed of a base rubber, which in an embodiment of the present invention is a rubber substantially the same as that of the base portion, and from 1 to less than 10 phr of a friction reducing element.

  • protuberances 36 generally comprised irregularly shaped- and sized masses, which are presently believed to be the result of an agglomeration or a plurality of PTFE particles massed together and not completely broken apart in the rubber mixing process to result in clumps in the otherwise generally homogeneous rubber matrix observable at the surface of the strip.
  • a particulate friction reducing element having a slightly larger average individual particle diameter, e.g., of greater than 10 ⁇ m and having a lesser tendency toward agglomeration could be utilized to result in individual protuberances of beneficial dimensions as further described below at the strip surface.
  • the surface of the wiper blade in contact with the windshield surface changes thus to a point wherein the low coefficient of friction strip 24 (or 26) engages the windshield, thus reducing the effective friction between the blade 10 and the windshield.
  • the protuberances 36 in the strip 24, 26 provide an essentially rough- or irregular strip surface that beneficially results in a reduction of the area of actual contact between the wiper blade 10 and the windshield surface when the base portion is sufficiently deflected, which serves to reduce the surface tension therebetween. This in turn allows the non-PTFE containing wiping lip 20 to quickly re-engage the windshield to provide its intended water removal function as designed in accordance with this particular embodiment.
  • the PTFE in the amounts and of the type employed in the composition of the strip described herein results in a beneficial reduced coefficient of friction in the strip 24, 26 over a broader operating temperature range than heretofore available.

  • the above-described protuberances may be absent from the strip surfaces. It is presently believed that by increasing the mix efficiency, i.e., the speed and/or temperature and/or duration of mixing, of the elastomer composition for the strip, particularly but not necessarily during the first pass, and/or selecting a friction reducing element having a suitable combination of either individual particle size or particle agglomerate size and agglomerate resistance to being broken apart during the mixing process, the protuberances including those at the surface of the strip 18, 20 may be eliminated.
  • FIG. 3 which furthermore illustrates an alternative embodiment of the present invention wherein the top-most portion of the strip 26 meets at the base portion to form a slight shoulder, as shown.
  • FIG. 4 A further embodiment of the present invention is illustrated in FIG. 4.
  • the strips 24, 26 do not form a shoulder with either the base portion 18 or the wiping lip portion 20, but extend substantially to the apex 22 of the base portion 18.
  • the particular embodiment of the present invention shown in FIG. 4 furthermore includes a backing member 40, which in the illustrated embodiment is in the form of a beam-type pre-curved spring backing member as disclosed for example in aforementioned U.S. Pat. No. 5,325,564.
