BRIEF SUMMARY
BACKGROUND
The present invention relates to a mirror for motor vehicle sun visors, provided with a hinged cover and, in particular, applicable to modular structure sun visors.
Technological improvements have been made in sun visors with which motor vehicles are equipped, particularly the passenger side sun visors with so-called vanity mirrors. The mirror is usually unit formed by a reflective surface and assembly and mounting members.
The vanity mirrors may be provided with devices directed to directional concealment of the reflective surface, in accordance with the interior of the vehicle passenger compartment, at the same time they preserve the reflective constants of the mirror surface and, therefore, the original quality of the image provided by said surface.
Some solutions are disclosed in the following Spanish Utility Models: Utility model No. 276,352, Utility model No. 276,353 and Utility model No. 276,822.
In the Utility models Nos. 276,352 and 276,353 the reflective surface concealing device is arrange on a hingedly mounted external covering flap, while in Utility model No. 276,822 said concealing device is arranged on a cover which sides in longitudinal guideways and may in turn be concealed in the sun visor structure.
This constructions disclosed in the Utility models Nos. 276,352, 276,353 and 276,822 are substantially complex to manufacture and assemble in the sun visor structures currently available on the market. This has a negative influence, raising the cost of the thus formed end product.
SUMMARY OF THE INVENTION
With a view to providing a new, economical solution to the problem raised by the concealment of the reflective surface of the so-called vanity mirror normally integrated in the structure of the passenger side sun visor, a mirror for motor vehicle sun visors is provided with a hinged cover which, is substantially different from prior art devices of this type.
The mirror for motor vehicle sun visors provided with a hinged cover according to the invention has a one-piece approximately rectangular frame with a frame provided for a reflective surface and having a U-shaped extension, and said extension has means for retaining and pivoting a hinged cover for concealing the reflective surface.
A further feature of the mirror of the invention is that the means for retaining and pivoting the hinged cover for concealing the reflective surface is formed on inner facing surfaces of the U-shaped is formed on inner facing surfaces of the U-shaped extension and includes two projections of sufficient dimensions which, respectively, extend perpendicularly to said facing surfaces. The projections have a sufficient number of planes delimiting the position of concealment of the reflective surface by said hinged cover.
Yet a further feature of the mirror of the invention is that the cover for concealing the reflective surface of the hinged mirror is an essentially rectangular one-piece member and has means for coupling said cover to the one-piece frame as well as means facilitating user operation of said cover once coupled to the one-piece frame.
The coupling means for the hinged cover to the one-piece frame is formed in the ends of one of the longer sides of said cover and includes U-shaped clamps extending substantially obliquely from the transverse axis of said cover.
The clamps, are provided with an internal contour snugly corresponding with the respective contour of the projections formed on the facing inner surfaces of the one-piece frame extension. The clamps and projections are engaged with each other, to allow the hinged frame to pivot and occupy set positions of use very a wide range.
An additional feature of the mirror of the invention is that when the one-piece frame is engaged with the cover and the latter is in the reflective surface concealing position, the joint action of the positioning planes formed on the projections of the one-piece frame extension and on the clamps of the hinged cover, prevents the cover from coming out, under normal conditions of use, position, either because
