Abstract:
A sun-shade assembly comprising:a stationary curved shaft;a tubular roller made of a resilient material, said roller being sleeved rotatably around said shaft, and having a curvature conforming with that of said shaft;a screen wound around said roller, said screen having a lower edge connected to said roller and an upper edge provided with a stretch rod which has a curvature conforming with that of said shaft;a torsion spring having a first end secured to said roller, and an opposite second end secured to said shaft;said screen being unwound from said roller when said stretch rod is pulled away from said roller, thereby resulting in rotation of said roller about said shaft in a first direction against biasing force of said torsion spring, said torsion spring biasing said roller to rotate about said shaft in a second direction opposite to the first direction to result in winding of said screen onto said roller; anda retaining sleeve which is sleeved rotatable on said shaft and which extends into said roller, said retaining sleeve being mounted on said roller so as to be co-rotatable therewith, said retaining sleeve having an outer wall surface formed with a retaining groove, said first end of said torsion spring being received in said retaining groove for connecting securely to said retaining sleeve, said retaining groove including a circumferentially extending groove portion and an axially extending groove portion extending from said circumferential grove portion, said first end of said torsion spring including a ring section received in said circumferential groove portion, and a linear section which extends from said ring section and which is received in said axially extending groove portion.
