BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to travel bags and more particularly, to such a travel bag, which is well protected against impact. [0003] 2. Description of the Related Art [0004] A conventional travel bag 10, as shown in FIG. 1, comprises a tough plastic box frame 11, a retractable handle 13 mounted on the back-side of the box frame 11, a fabric covering 14 covered on and fixedly secured to the box frame 11 with stitches, wheels 12 pivotally installed in the bottom side of the box frame 11 and exposed to the outside of the fabric covering 14, and a cover panel 15 hinged to the fabric covering 14 at one side, and a zipper 16 adapted to close/open the cover panel 15. [0005] The aforesaid conventional travel bag 10 has drawbacks as follows: [0006] 1. The box frame 11 is not collapsible. In factory, box frames 11 cannot be received one inside another to reduce space occupation before delivered to the assembly line. [0007] 2. The box frame 11 can only protect the top and bottom sides and the two opposite lateral sides of the travel bag 10 against impact, and the back side of the travel bag 10 is not well protected, and therefore the corner area of the box frame 11 tends to be damaged. [0008] 3. The monotonous fabric covering 14 does not cause a unique sense of beauty. SUMMARY OF THE INVENTION [0009] The present invention has been accomplished under the circumstances in view. According to one aspect of the present invention, the travel bag comprises two symmetrical side panels arranged in parallel, a top panel mounted on the side panels at the top side, a bottom panel mounted on the side panels at the bottom side, a plurality of wheels pivotally mounted in the bottom side of the bottom panel, and a retractable handle coupled to the top panel. In factory, all parts can be closely received together before delivery to the assembly line, thereby saving much storage space. [0010] According to another aspect of the present invention, the side panels each have a peripheral flange for the mounting of a fabric covering. [0011] According to still another, aspect of the present invention, the side panels each further have a top lug and a horizontal bottom wall. Further, a reinforcing plate is affixed to the top lugs of the side panels to support the top panel and to reinforce the structural strength of the top panel. Further, the bottom pane is affixed to and supported on the horizontal bottom walls of the side panels. BRIEF DESCRIPTION OF THE DRAWINGS [0012] FIG. 1 is an exploded view of a travel bag according to the prior art. [0013] FIG. 2 is an exploded view of a travel bag according to a first embodiment of the present invention. [0014] FIG. 3 is an elevational assembly view of the travel bag according to the first embodiment of the present invention before installation of the fabric cover member. [0015] FIG. 4 is an elevational assembly view of the travel bag according to the first embodiment of the present invention after installation of the fabric cover member. [0016] FIG. 5 is an elevational view of a side panel for a travel bag according to a second embodiment of the present invention.

A reinforcing plate 24 is affixed to the top lugs 22 of the side panels 20 to support the top panel 25 and to reinforce the structural strength of the top panel 25. The bottom panel 26 is affixed to and supported on the horizontal bottom walls 23 of the side panels 20.
