Description

  The present invention relates to a wiper blade assembly. More particularly, the present invention relates to a resilient wiper blade having an embedded support beam member.

  A common disadvantage in conventional automotive wiper designs is that streaks or streaks remain on the surface of the wiped windshield. This problem is often due at least in part to the wiper assembly being unable to apply a uniform wiping force over the length of the wiper blade (relative to the windshield surface). The phenomenon that the wiping force applied to the wiper blade is non-uniform is characteristic of a conventional wiper assembly having a superstructure that applies a load only at a relatively wide distance to the wiper blade. As a result, little force may be applied at each position between these intervals.

  Although a relatively large number of patents with different designs have been granted in the field of wipers, wiper designs usually have a significant commonality of approaches to basic functions. Therefore, many of the wipers are characterized by an upper structure that distributes the force applied by the central wiper arm, an intermediate wiper blade support member, and a flexible wiper blade insert that directly performs the function of wiping the windshield. The various wiper designs share certain structural commonality and therefore share certain drawbacks when performing basic tasks. For example, modern wiper assembly designs require force distribution means to distribute the force applied by the wiper arm along the length of the flexible wiper blade. This is because the wiper blade must be able to bend along its length in order to remain in wiping contact with the surface of the windshield having a varying radius of curvature.

  U.S. Pat. No. 3,104,412 to Hinder discloses an elastic support member or superstructure made of molded plastic having a concave surface with a curvature substantially equal to the maximum curvature of the surface of the windshield to be wiped. . The support member is directly attached to the flexible wiper blade. In this arrangement, it goes without saying that the joint between the support member and the wiper blade is exposed to the component, and the force cannot be evenly distributed when the radius of curvature changes along the length of the blade.

  Another conventional wiper assembly includes support beam devices along both sides of the elastic wiper portion as a means for providing structural support and downward wiping force. Such a support beam device is often composed of an elastic wiper member having a support beam penetrating the inside in the longitudinal direction from end to end.

  A common problem with this design is that the elastic portion twists around the support beam due to the frictional force applied to the wiper blade during vibration. Therefore, external devices such as clips and other means must be provided to prevent situations where the wiping quality and blade service life are compromised.

  The present invention overcomes the above and other disadvantages by providing a wiper having an embedded beam while maintaining the variability of the design that provides the wiper for various applications.

  Further areas of applicability of the present invention will become apparent from the detailed description below. The following detailed description and examples illustrate preferred embodiments of the present invention, but are intended to be exemplary only and are not intended to limit the scope of the invention.

  It is an object of the present invention to provide a wiper having an embedded beam that provides a structural and uniform support for the wiper blade during various vibrations.

  Another object of the present invention is to provide a wiper blade having an embedded beam that prevents rotation and twisting of the elastic wiper blade around the support beam.

  It is another object of the present invention to provide a wiper blade having an embedded beam that further includes a wind deflector portion that further prevents twisting of the elastic wiper blade around the beam.

  Another object of the present invention is to provide a wiper blade having an embedded beam that can be removably attached as a unit to a connector device.

  Another object of the present invention is to provide a wiper beam having a structure that prevents rotation of an elastic portion relative to the beam while the beam is separated from the connector device of the wiper.

  Another object of the present invention is to prevent / suppress exposure of the support beam to the environment by embedding it in an elastic medium.

  Finally, another object of the present invention is to provide a wiper blade having an embedded beam that further includes a flow path along the embedded beam member capable of spraying cleaning / thaw solution along the length of the wiper blade. There is to do.

  These and other purposes will become more apparent from the following description. The present invention includes an improved wiper blade assembly having a resilient wiper member and further including a longitudinal passage therethrough. A support beam having a predetermined curvature and a shape complementary to the longitudinal passage is inserted into the passage to prevent rotational twisting of the elastic member around the beam. Another embodiment includes a longitudinal flow path provided along the support beam and fluidly connected to the windshield fluid source. The fluid is selectively discharged onto the windshield through a plurality of openings provided in the elastic member and connected to the flow path. Yet another embodiment further includes a wind deflector portion extending along at least a portion of the upper surface of the elastic member to further prevent twisting of the elastic member around the beam and increase the downward force of the wiper assembly against the windshield. Including.

  The invention will be better understood from the following detailed description and the accompanying drawings.

The leg members 109 and 110 extend downward along the side surface 111 of the elastic member 113 and function as a side support for preventing the embedded beam 10 from rotating.

  An important feature of the mounting assembly as described herein is that there is no intimate contact between the connector device 100 and the beam 99. Therefore, frictional wear of the beam 99 can be prevented, and when using a fluid in another embodiment, the sealed flow path 98 can be formed.
