Definitions

  • the present invention relates to an attachment device for connecting a wiper blade to a wiper arm in the vehicles such as automobiles.
  • a wiper device comprising an elastic wiper profile for wiping the surface of the windscreen or rear window, an elongated, resilient carrier frame for supporting said profile and a connecting device for an oscillating wiper arm have been known for a long time.
  • the wiper blade should be pivotally connected to the free end of the wiper arm so as to rotate around a pivot axis.
  • Such a rotatable connection is required to be secure enough at one hand to resist the forces acting in all three directions.
  • One of the arm-blade connections meeting said requirements is the bayonet design.
  • a wiper is described, that is mounted onto a bracket fixed to the vertebra and where to a U-shaped adapter pivotally connected to the bracket is mounted .
  • the circular protuberances serving as pins at both sides of the bracket are seated into the holes on both flanks of the adapter and thus, the adapter is pivotally connected to the bracket.
  • the connection between the arm and the adapter is again realized by a resilient tongue provided on upper surfaces of the adapter engaging in a corresponding hole provided on the upper surfaces arm.
  • the arm is generally produced from metal and the adapter that is produced from plastic as a requirement for elasticity is of different color and luminosity. Therefore, a portion of the adapter being visible on the top and lateral surfaces of the arm that is visible to the end user causes an unaesthetic appearance.
  • EP1332076 discloses a connection between arm and wiper blade wherein the all connection elements that provides the attachment between arm and wiper blade are almost completely covered by the arm.
  • Holding elements are arranged within the U- shaped wiper arm and extending downwards from the top wall thereof. Pins at both sides of the bracket are seated into the holes provided on the holding elements and thus, arm is pivotally connected to the bracket.
  • the holes have a closed circumference to enhance the retention of the arm onto the bracket/adapter in the horizontal and vertical directions whereas the longitudinal retention is enhanced by a resilient tongue provided on the adapter engaging in a correspondingly shaped hole provided in the arm.
  • the disclosed adapter part can be mounted onto the bracket by resiliently stretching the side walls outwards. However in case the user applies excessive force during assembly, the adapter may lose its function.
  • connection elements on the blade are almost completely covered by the arm so as to, on one hand, provide an aesthetic appearance and on the other hand to protect the connection region from external factors, and also provides the arm and the blade to be locked in a safe manner against the forces in all directions.
  • a connecting device that provides aesthetic appearance and also the safe connection of the wiper arm and the blade is disclosed.
  • the connecting device comprises a bracket which is fixed at approximately the central region of the blade by preferably gripping the vertebra with its hook-shaped legs.
  • a pin is preferably provided on the outer surface of bracket top wall.
  • the wiper arm on the other hand, is provided with two extensions protruding downwards from the inner surface of its top wall and form an inverted U-shaped pin housing.
  • An articulated connection between the wiper arm and the bracket is realized by means of the pin being seated into the pin housing.
  • the arm-blade locking is realized by means of a sliding element that is held within the wiper arm. A sliding element is pushed forward in the longitudinal direction until its locking portions close the lateral spaces between pin housing and side walls of the wiper arm. As a result, connection is obtained between the arm and the blade which is resistant against the forces acting in all directions.
  • Figure l is the exploded isometric view of the wiper of the present invention.
  • Figure 2a, 2b and 2c is the isometric, sideways and frontal view of the blade with the bracket integrated thereon.
  • Figure 3 a and 3b are the two different isometric views of the wiper arm.
  • Figure 4 is the isometric view of the sliding element.
  • Figure 5a is the cross-sectional view showing the assembly of the sliding element into the wiper arm.
  • Figure 5b is the cross-sectional view showing the sliding element mounted within the wiper arm
  • Figure 6a and 6b are the cross-sectional view showing the assembly process of the articulated connection.
  • Figure 6c is the cross-sectional view showing the bracket mounted with the wiper arm in the articulated manner.
  • Figure 7a is the cross-sectional view of connection device of the present invention in the unlocked state.
  • Figure 7b is the cross-sectional view of connection device of the present invention in the locked state.
  • the connecting device is used for connecting a wiper blade (4) having at least one elastomeric wiper profile (7) with a lip portion for wiping the glass surface, an arc-shaped resilient metal vertebra (6) and a bracket (3) fixed to the vertebra (6) at the longitudinal middle region, to a wiper arm (1) one end of which is connected to a motor in the vehicle so as to rotate around a pivot axis (8).
  • the connecting device comprises said bracket (3), an free end (10) of the wiper arm (1) connected to the bracket (3) so as to rotate around said pivot axis (8) and a sliding element (9) held within the wiper arm (1).
  • Sliding element (9) provides attachment and detachment of the wiper blade (4) and wiper arm (1).
  • the bracket (3) is fixed to the blade (4), preferably directly to the vertebra (6) by means of its hook-shaped legs (33).
  • the body portion (30) above these legs (33) has preferably two parallel side walls (31) and a top wall (32) joining former two (31).
  • pin (34) is arranged on the outer surface (320) of the top wall (32) of the bracket. Between the pin (34) and outer surface (320) of the top wall (32), base plate (35) connecting the former two (320, 34) can be formed.
  • the bracket (3) is produced as a single-piece.
  • Pin (34) is in the form of horizontal cylinder so as to head surfaces (341) are parallel to the side walls (31) of the bracket (3).
  • pin (34) is in the form of bulging horizontal cylinder. Length (1) of the pin (34) is smaller than the diameter (d) thereof.
  • the said free end (10) of the wiper arm (1) comprises two parallel side walls (11) and a top wall (12) and a front wall (13) joining the former two.
  • the front wall (13) is partially empty by means of a window (14) with its lower portion (130) open.
  • a pin housing (15) that grips the pin (34) on the bracket (3) in the assembled state is formed on the inner surface (120) of the top wall (12).
  • the pin housing (15) is in the form of an inverted U and is preferably formed by means of two arc-shaped extensions (151) that extend downwards.
  • free end (10) of the wiper arm (1) comprises guiding elements (17) extending downwards from the inner surface of the said top wall.
  • a rail (18) extending longitudinally is provided on the inner surface (120) of the top wall (12).
