Abstract

A contractible windshield wiper structure includes: a rack; two contractible units movably and separately installed at both ends of the rack, and each contractible unit having a fixed rod; a sliding rod movably sheathed onto the fixed rod, and a bow-shaped clamping device installed separately at the fixed rod and an end of the sliding rod; and a blade installed onto the bow-shaped clamping device of each contractible unit, such that each contractible unit can be used for adjusting a windshield wiper to the required size to fit different models of cars.

Claims

1. A contractible windshield wiper structure, comprising:

a rack;

two contractible units, movably and respectively installed on both ends of said rack, and said each contractible unit comprising a fixed rod, a sliding rod movably sheathed onto said fixed rod, and a bow-shaped clamping device installed separately at said fixed rod and an end of said sliding rod; and

a blade, installed on said bow-shaped clamping device of each contractible unit.

2. The contractible windshield wiper structure of claim 1, wherein said rack includes a connecting portion disposed at the middle of said rack.

3. The contractible windshield wiper structure of claim 1, wherein said fixed rod of each contractible unit includes a pivot disposed at an appropriate position and movably coupled to said rack, and a surface of said fixed rod includes a plurality of stop plates, and a surface of said sliding rod includes a plurality of positioning notches, and said pivot of said fixed rod includes a resilient plate of said positioning notch that props and presses against said sliding rod.

4. The contractible windshield wiper structure of claim 1, wherein said fixed rod of said each contractible unit includes a corresponding slide slot disposed at an appropriate position, and said sliding rod includes a corresponding slot disposed separately on both sides of said sliding rod and corresponding to said slide slot, and a fixing element is passed through said slide slot and said corresponding slot.

5. The contractible windshield wiper structure of claim 1, wherein said fixed rod of each contractible unit includes a corresponding through hole, and said sliding rod includes a groove hole disposed at an appropriate position and corresponding to said through hole, and said through hole includes a pin passed through said groove hole.

6. The contractible windshield wiper structure of claim 1, wherein said fixed rod of each contractible unit includes a transverse rod disposed at an appropriate position, and both sides of said sliding rod separately have a slide slot sheathed onto said transverse rod.

7. The contractible windshield wiper structure of claim 1, wherein each contractible unit includes said fixed rod, a link rod and said sliding rod, and a pivot is installed separately at appropriate positions of said fixed rod and said link rod, and a surface of said fixed rod includes a plurality of stop plates, and surfaces on both sides of said link rod separately include a plurality of stop plates and positioning notches, and a surface of said sliding rod includes a plurality of positioning notches, and said pivot of said fixed rod includes a first resilient plate propping and pressing at said positioning notch, and said pivot of said link rod includes a second resilient plate propping and pressing at said positioning notch of said sliding rod.

8. The contractible windshield wiper structure of claim 1, further comprising a shock absorbing element installed between each fixed rod and said bow-shaped clamping device.

9. The contractible windshield wiper structure of claim 1, further comprising a shock absorbing element installed between sliding rod and said bow-shaped clamping device.
