Wind deflecting plate for air conditioning grilles

A wind deflecting plate for an air conditioning grille vertically and swingably mounted at downstream side of a horizontal cylindrical rotor to change the blowing direction of the wind generated by said rotor, the deflecting plate comprising:

• a flexible plate to be curved when said deflecting plate is swung for smoothly changing the blowing direction, said flexible plate being formed of a first thermoplastic material;
• a front rigid support supporting a downstream end of said flexible plate;
• and
• a rear rigid support supporting an upstream side of said flexible plate, said supports being formed from a second thermoplastic material, said first and second thermoplastic materials being the same type of material and having similar melting points but different hardnesses and stiffnesses, said flexible plate being fusion-bonded to said supports.
