FIELD OF THE INVENTION

The present invention is related to a method for mounting fastening structure, particularly to a method for mounting fastening structure applied to an internal window frame having an automobile sunshade.

BACKGROUND OF THE INVENTION

Presently, the ways for connecting an automobile sunshade to a window frame on the market are substantially classified into: 1. utilization of a plurality of suction cups adsorb to the internal window frame; 2. adsorbing the automobile sunshade to the internal window frame in accordance with principles of electrostatics; 3. fastening a plurality of projections, extending from the periphery of the automobile sunshade, into notches of the window in a predetermined orientation correspondingly, such that the automobile sunshade is provided with the functions of quick positioning and convenience of removal in the practical use.

An existing automobile sunshade in the prior U.S. Pat. No. 7,131,683 is cited herein firstly, in which the sunshade is positioned by a plurality of fastening blocks adhered onto a top edge and a bottom edge of an internal window frame of an automobile, and each of the fastening blocks has an accommodated region with a lengthwise positioning space and a narrower opening, so as to cover flexible material of the sunshade to facilitate flexible insertion and positioning, as well as facilitate lifting or lowering the window without removal of the sunshade in the practical use. Moreover, the sunshade is capable to be removed by simple flexure in accordance with the flexibility of the sunshade, if intended. However, it is necessary to slightly squeeze into and/or pull out of each positioning end on the periphery of the sunshade where combined with the interior of the fastening blocks of the window, one by one, while the sunshade is being positioned onto or removing from the window, and in consequence it is slightly time-consuming during the process.

For the further improvement of the above-mentioned sunshade used for blocking sun irradiating the interior of vehicle directly so as to eliminate inconvenience existed in positioning and removing, an existing prior U.S. Pat. No. 8,365,799 cited secondly has mentioned a fastening structure of sunshade, in which the sunshade may be quickly and conveniently positioned on the internal surface of the internal window frame in the practical use, owing to a metal portion correspondingly adsorbs a plurality of magnetic elements which are covered inside the periphery of the sunshade thereof, wherein the metal portion adheres to the internal surface of the internal window frame or the interior of each of the clamping members in a corresponding orientation. In such method for mounting the sunshade, it is normal for the user to predict the adhesive position of the metal portion of each of the clamping members one by one in a manner of visual observation before adhering to the internal surface of the internal window frame. However, it is not only inconvenient to operate during the process of adhesion, but also prone to occur misalignment of the plurality of magnetic elements inside the periphery of the sunshade. If the displacement of each of the clamping member occurred upon adhesion, it would be time-consuming for repositioning and reinstallation after removal of the sunshade. Further improvement of fixing manner of mounting each clamper by adhesion via visual prediction is required.
