Definitions

  • the present invention relates to windshield wipers used in vehicles comprising a single piece elastic wiper profile mounted on a longitudinal elastic metal framework and plastic end caps at each end connecting the framework and the windshield wiper and clips disposed on the longitudinal axis of the windshield wiper and a connection element suitable for attaching the windshield wiper arm thereon.
  • a resilient wiper profile is wedged into the one-piece metal framework, and the separate spoiler element is mounted on top of these and side covers at each end are provided for joining the spoiler and the metal framework.
  • the framework is a flat, long bow-shaped element having a centrally disposed longitudinal opening.
  • the wiper profile has channels that form a neck portion to be fitted into the longitudinal opening. The profile is fixed into the framework longitudinally by means of these channels.
  • the spoiler portion of the wiper is composed of two separate elastic pieces having an A-shaped profile, and is mounted on the very top after the wiper-framework connection is made, such that the side walls of the framework left outside are covered from the sides and below.
  • the first and second portions of the spoiler are assembled separately from each other to allow for the installation of the connection element at the center that is used for connecting the windshield wiper arm attached to the motor on the vehicle.
  • the system is completed with the connection element being locked into this indentation by inserting through the holes in the framework and the side covers being mounted at each end.
  • the most important disadvantage of this system is the multiple number of components to be installed like the first and second halves of the spoiler in addition to the other components leading to assembly and quality problems and furthermore the system not having a stable configuration.
  • the metal framework is composed of two identical halves. Both of these halves are mounted to the longitudinal channels on the elastic wiper from both sides and are fixed to each other by either additional connection elements at both ends, or by bridges, preferably made of the same material, welded to the two halves of the framework.
  • the spoiler is independent of the portion of the profile wiping the glass.
  • the base has a triangular cross-section such that it can be seated on the framework.
  • the connection of the spoiler and the system is provided by an auxiliary component.
  • a protrusion having a circular cross-section of the elastic wiper profile left above the channels wherein the framework is inserted allow for a mechanical connection.
  • the long auxiliary component made of a more rigid material and having a bottom facing C cross-section is seated on this protrusion along the length of the wiper.
  • the inner portion of the spoiler has a housing that can encircle the more rigid intermediary profile and the installation of the system is completed by mounting this housing of the spoiler on this profile. There is no direct connection of the spoiler with the framework. Even though this technique provides a more stable and safer assembly of the spoiler on the system than the arrangement in US2006/0026786, the production is quite difficult due to the required auxiliary components.

  • FIG. 11 - is the view of the clip used in the system.
  • the present invention relates to a development in the windshield wipers used in vehicles.
  • the windshield wiper (1) of the present invention is comprised of an elastomer based resilient wiper profile (5) having lengthwise channels (7a. and 7.b) along on both of its sides, a resilient metal framework (10) mounted on the channels (7a. and 7.b) on both sides of this profile (5), end caps (11) on both ends that cover the upper portion (9) of the elastomer wiper profile (5) and the framework (10), a connection element (12) situated at the center of the windshield wiper (1) whereto the wiper arm (3) fixed to the vehicle at the other end can be attached by means of an adapter (2) so that the windshield wiper (1) can function over the glass and clips (13) situated along the longitudinal axis of the windshield wiper (1) at certain intervals, to strengthen the connection by grappling the upper portion (9) of the wiper profile (5) and the metal framework (10).
  • the curvature of the windshield wiper (1) resembles a bow.
  • the elastomer based resilient windshield wiper profile (5) is a component produced at one go by injection method, comprising an end portion (6) that contacts with the surface of the glass actualizing the wiping process, lengthwise channels (7.a and 7.b) situated along both sides for emplacing in the metal framework (10), a spoiler (9) having a triangle cross- section, preventing the windshield wiper (1) from being lifted at high speeds by providing the wind load to press towards the glass and a channeled body (8) of wiper profile enabling the wiper profile (5) to stretch suitably such that the end portion (6) of wiper profile always contacts the glass with the most suitable angle during the movement of the windshield wiper (1) on the glass.
  • the spoiler (9) portion of the wiper profile (5) is not provided at the center of the windshield wiper (1) along a certain length to form the housing-clearance (14) wherein the connection element (12) will be disposed.
  • the spoiler (9) portion is also not provided at both ends of the wiper profile (5) along a certain length so as to form the assembly region wherein the end caps (11) will be mounted.
  • the flat metal framework (10) made of a resilient metal, bent so as to form the desired bow curvature, is comprised of two symmetrical parts (10.a andlO.b) and these parts (10.a andlO.b) are arranged in the channels (7.a and 7.b) at both sides of the wiper profile (5) along the length of the windshield wiper (1). Since the width of each symmetrical part (10.a andlO.b) forming the metal framework (10) is more than the width of the channels (7.a and 7.b), some portion of the metal framework (10) projects from both sides forming the protrusions (17.a and 17.b).
  • each of the twin flat parts (10.a andlO.b) of the framework (10) a recessed profile (15) is provided, designed for the end caps (11) to be fitted in and locked and a bevel (4) of maximum 45° angle on the outward facing regions of these ends, designed so that the end caps (11) can push the two halves (lO.a andlO.b) of the framework (10) towards each other.
  • the framework (10) attached to the windshield wiper arm (3) from one point by means of the connection element (12), provides the pressure force received from the windshield wiper arm (3) on its center point to be distributed homogeneously at each point of the windshield wiper (1) by means of the resiliency and curvilinear configuration thereof.
  • the end caps (11) are plastic parts situated at each end of the windshield wiper (1), clasping the spoiler (9) portion of the wiper profile (5) and the metal framework (10), with outward facing parts being closed at each end.
  • the profile of the end caps (11) is A-shaped at the upper region (19) to clasp the spoiler (9).
  • two of its legs (20) are bended at the right and left hand side to form a recess (15) such that the ends of the metal framework (10) can be seated.
  • the end caps (11) are fitted at both ends such that the metal framework (10) is inserted into the recess (15) and the spoiler
  • connection element (12) is an inelastic element from metal or plastic which is seated in the housing (14) formed by the spoiler (9) at the upper portion of the wiper profile (5).
  • One end of the windshield wiper arm (3) is connected to the motor on the vehicle and the other end is connected to the wiper profile (5) by means of the connection element (12) so that the windshield wiper (1) can maintain its wiping function.
  • An intermediary element generally called the adapter (2) is connected to the connection element (12) and the windshield wiper arm (3) at the same time serving for the completion of this connection.
  • connection element (12) is made up of two identical halves (12.a and 12.b). In each half, a slot and a riveting extension are provided so that it can be attached to the opposite other half. When the halves (12.a and 12.b) are opposite each other for assembly, the riveting extensions and the slots are aligned and are fitted into one another such that their surfaces are in full contact. Furthermore a pin hole (25) is provided at each half (12.a and 12.b) which will be at the same axis after the assembly. The connection element (12) and the wiper arm (3) can be joined by inserting a pin through this pin hole (25). Under each half (12.a and 12.b) of the connection element (12), a channel (27) is provided that extends lengthwise parallel to the longitudinal axis of the windshield wiper (1). The protrusions (17. a and 17.b) of the metal framework
  • the clips (13) are elements that connect the framework (10) and the elastic wiper profile (5) together so that the system is more reliable at high speeds. At least two clips (13) are provided along the windshield wiper (1) and this number can increase depending on the length of the windshield wiper (1). Clips (13) are inelastic, short elements, made of plastic or metal, and having an A shaped cross-section. Both of its legs (20) are bended towards each other at the bottom side.
