Abstract

A windshield wiper includes a wiper post and a connection unit which is used to connect the wiper post and a wiper arm. The wiper rod has a bottom connected with a rubber blade. The wiper post has an opening at a central portion thereof, a recess at a central bottom of the opening, and a resilient plate disposed on the recess. One end of the resilient plate is connected with the bottom of the opening, and another end of the resilient plate is suspended above the recess and has an engaging buckle. The opening has protruding steps which are formed at two sides of the resilient plate. The protruding steps each have a vertical surface formed with a lumpy section. The connection unit is detachably mounted in the opening of the wiper post. The connection unit has a bottom formed with a protruding platform corresponding to the opening. The protruding platform has a slide trough at a central portion thereof corresponding to the resilient plate. Two sides of the protruding platform each have a vertical surface formed with a lumpy portion corresponding to the lumpy section of the opening.

Claims

1. A windshield wiper, comprising a wiper post and a connection unit which is used to connect the wiper post and a wiper arm, characterized by:

the wiper post having a bottom connected with a rubber blade, the wiper post having an opening at a central portion thereof, a recess at a central bottom of the opening and a resilient plate disposed on the recess, one end of the resilient plate being connected with the bottom of the opening, another end of the resilient plate being suspended above the recess and having an engaging buckle, the opening having protruding steps which are formed at two sides of the resilient plate, the protruding steps each having a vertical surface formed with a lumpy section;

the connection unit being detachably mounted in the opening of the wiper post, the connection unit having a bottom formed with a protruding platform corresponding to the opening, the protruding platform having a slide trough at a central portion thereof corresponding to the resilient plate, two sides of the protruding platform each having a vertical surface formed with a lumpy portion corresponding to the lumpy section of the opening.

2. The windshield wiper as claimed in claim 1, wherein a side wall of the opening is formed with an engaging groove and a stop piece which are spaced, an end of the connection unit having a protruding rib corresponding to the engaging groove and a notch corresponding to the stop piece, when the connection unit being mounted in the opening, the notch being against the stop piece and the protruding rib being engaged in the engaging groove.

3. The windshield wiper as claimed in claim 1, wherein an engaging platform is provided on the slide trough, after the connection unit being mounted, the engaging buckle of the resilient plate cooperating with the engaging platform to press the connection unit tightly.

4. The windshield wiper as claimed in claim 1, wherein the connection unit is a first connection unit used to connect a hook-typed wiper arm, the first connection unit having a limit trough at a central portion thereof and a cylindrical post in the limit trough, the limit trough being to receive a connection member therein, the connection member having a hollow middle portion and an engaging recess facing down, when assembled, the engaging recess of the connection member being engaged on the cylindrical post of the limit trough of the first connection unit, front and rear ends of the connection member each having a pin hole for insertion of a pin which is pivotally connected with an upper lid, the upper lid having a front end formed with a pivot hole and a rear end formed with a protrusion, the protrusion having a curved side surface to secure the hook-typed wiper arm.

5. The windshield wiper as claimed in claim 1, wherein the connection unit is a second connection unit used to connect a pin-typed wiper arm, the second connection unit having a pivot hole at a top end thereof, a connection member fitted on the second connection unit, the connection member having a hollow lower end and a U-shaped engaging trough facing down, the connection member having a circle hole corresponding in position to the pivot hole and a plurality of slots on a top end thereof to communicate with the engaging trough.

6. The windshield wiper as claimed in claim 1, wherein the connection unit is a third connection unit used to connect a conventional wiper arm, the third connection unit having a V-shaped opening, a mounting hole, a limit step beside the opening and a resilient engaging piece which is disposed inside the third connection unit close to the mounting hole, an upper end of the third connection unit having a buckle recess and a pivot at one end of the buckle recess for connection of an upper lid, the upper lid having a front end formed with an open recess corresponding to the pivot, two engaging detents at a middle portion thereof and a press block at a rear end thereof.
