Easy-to-operate sunshade

1. A sunshade comprising:

a supporting rod having an upper end;

a holding sleeve pivotably mounted to the upper end of the supporting rod;

an arcuate tube slidably extended through the holding sleeve, with the arcuate tube including a first end adapted for coupling with a canopy support frame and including a second end;

a reel mounted to the second end of the arcuate tube, with the reel including a projection;

a coupling member mounted to the supporting rod and including a notch, with the projection being releasably engaged with the notch when the arcuate tube is in a folded position;

a first connecting member mounted to the supporting rod;

a second connecting member including a body mounted around the second end of the arcuate tube, with the second connecting member further including a lever pivotally coupled to the body, with the lever being movable between a clamping position and a released position;

a connecting rod including a first end pivotally connected to the first connecting member and a second end pivotally connected to the second connecting member; and

a positioning member releasably engaged with the first connecting member for positioning the connecting rod in place, with the connecting rod being pivotable relative to the first connecting member when the positioning member is disengaged from the first connecting member;

wherein when the lever is in the clamping position, the second connecting member is fixed on the arcuate tube, and the second end of the arcuate tube is supported by the connecting rod; and

wherein when the lever is in the released position, relative sliding movement between the second connecting member and the arcuate tube is allowed.

2. The sunshade as claimed in claim 1 further comprising a mounting sleeve mounted around the supporting rod, and wherein the first connecting member extends from the mounting sleeve.

3. The sunshade as claimed in claim 2 wherein the first connecting member includes a slot for pivotally receiving the first end of the connecting rod.

4. The sunshade as claimed in claim 1 wherein the positioning member is a sleeve slidably mounted on the connecting rod between a first position engaged with the first connecting member and a second position disengaged from the first connecting member.

5. The sunshade as claimed in claim 1 wherein the second connecting member includes two ears between which the second end of the connecting rod is pivotally mounted.

6. The sunshade as claimed in claim 1 wherein the body is substantially C-shaped and includes a slit, with the body further including two spaced lugs, with the lever including a screw pivotally connected to an end thereof, and with the screw extending through the lugs, allowing the lever to pivot between the clamping position and the released position.

7. The sunshade as claimed in claim 1 wherein the reel includes a gripping handle.

8. The sunshade as claimed in claim 1 wherein the coupling member includes a ring mounted around the supporting rod, with the ring including a protrusion in which the notch is defined.

9. A sunshade comprising:

a supporting rod having an upper end;

a holding sleeve pivotably mounted to the upper end of the supporting rod;

an arcuate tube slidably extended through the holding sleeve, with the arcuate tube including a first end adapted for coupling with a canopy support frame and a second end;

a reel mounted to the second end of the arcuate tube, with the reel including a projection;

a coupling member mounted to the supporting rod and including a notch, with the projection being releasably engaged with the notch when the arcuate tube is in a folded position;

a mounting member mounted to the supporting rod;

a quick release mounted around the second end of the arcuate tube; and

a connecting rod including a first end pivotally connected to the mounting member and a second end pivotally connected to the quick release;

wherein when the quick release is in a clamping position, the quick release is fixedly clamped on the arcuate tube, and the second end of the arcuate tube is supported by the connecting rod;

wherein when the quick release is in a released position, relative sliding movement between the quick release and the arcuate tube is allowed.

10. The sunshade as claimed in claim 9 further comprising a positioning member releasably engaged with the mounting member for positioning the connecting rod in place, with the connecting rod being pivotable relative to the mounting member when the positioning member is disengaged from the mounting member.

11. The sunshade as claimed in claim 10 wherein the positioning member is slidably mounted on the connecting rod between a first position engaged with the mounting member and a second position disengaged from the mounting member.

12. The sunshade as claimed in claim 9 wherein the reel includes a gripping handle.

13. The sunshade as claimed in claim 9 wherein the coupling member includes a ring mounted around the supporting rod, with the ring including a protrusion in which the notch is defined.
