Embodiment Construction

[0022]With reference to FIGS. 1 and 2, a retractable window shade with multiple shading gradations in accordance with the present invention comprises a guide rail (30), a major shade body (10), a major cord assembly (40), a secondary shade body (20) and a secondary cord assembly (50).

[0023]With further reference to FIG. 3. the guide rail (30) is elongated and has a bottom, a front, a rear, two ends, two mounting holes (33), two one-way arresting mechanisms (60), two major holes (31) and two secondary holes (32). The mounting holes (33) are formed through the bottom of the guide rail (30) respectively near the ends of the guide rail (30).

[0024]With further reference to FIG. 4, the one-way arresting mechanisms (60) are mounted on the guide rail (30) respectively near the ends of the guide rail (30) and may be mounted respectively in the mounting holes (33) in the bottom of the guide rail (30). Each of the one-way arresting mechanisms (60) may have a housing (61), a retain member (62) ...

Abstract

A retractable window shade with multiple shading gradations has a guide rail, two shade bodies and two cord assemblies. The guide rail has two one-way arresting mechanisms. The two shade bodies have different opacities and each shade body has a top side mounted on the guide rail and a lower section. The cord assembles are respectively mounted through the one-way arresting mechanism and connected to the lower sections of the of the shade bodies. The cord assemblies are pulled to rise the lower sections of the shade bodies. When the force for pulling one shade body is released, the cords are selectively arrested by the one-way arresting mechanisms to hold the shade body in a proper position. By expanding both of, one of or none of the shade bodies, the retractable window shade provides a proper proportion of shading sunlight with appropriate, comfortable and mild brightness.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a retractable window shade, and more particularly to a retractable window shade with multiple shading gradations.[0003]2. Description of Related Art[0004]A conventional retractable window shade generally has a single shade body. The shade body is expanded to shade outdoor sunlight or retracted to allow the outdoor sunlight to completely pass through a window to make an indoor environment bright.[0005]According to varied weather, the sunlight has varied brightness. However, the conventional retractable window shade merely has a single shade body such that the conventional retractable window is limited to alternatively provide shading effects, dark or bright. But, there are multiple gradations between dark and bright, the conventional retractable window shade with a single shade body is unable to shade outdoor sunlight in a proper proportion to provide an indoor environment with an appropr...
