Roller device of luggage case

#1. Field of the Invention

#The present invention relates to a roller device of luggage case, more particularly, to a luggage case having at least two retractile mechanisms with a roller device at each bottom side. The retractile mechanism is connected with retractable handle pivotally so that the rollers stick outside the bottom of the luggage case when the retractable handle is pulled up and completely hides within the luggage case by folding up the retractable handle. Therefore, the luggage cases have a better outlook and avoid dragging with other luggage when moving.

#2. Description of the Prior Art

#The accomplishment of the above-mentioned object of the present invention will become apparent from the following description and its accompanying drawings which disclose illustrative an embodiment of the present invention, and are as follows:

#FIG. 1 is an illustration of the present invention being disposed inside the luggage case.

#FIG. 2 is a perspective view of the present invention organized in the luggage.

#First of all, referring to FIG. 1, FIG. 2, and FIG. 3, the present invention includes a luggage case 1, a retractable handle 2 and at least two rollers 3 at the bottom of the luggage case 1. The invention features on that the roller 3 is arranged inside a retractile mechanism 4 having a housing 41, a lateral covering plate 42, a bottom covering plate 44, a roller support 43, a movable vertical stick 45, a swing panel 46 and a spring 47. The lateral covering plate 42 is arranged at one side of the housing 41 and the bottom covering plate 44 is coaxial to the roller 3—each plate formed part of the lateral side and the bottom side of the luggage case 1 respectively. The roller 3 is pivoted at one end of the roller support 43 while the movable vertical stick 45 is on the other end of the roller support 43 pivotally. The top of the movable vertical stick 45 is hooked with the swing panel 46. One end 461 of the swing panel 46 is pivoted on the wall of the luggage case 1 while the other end 462 is connected with the retractable handle 2. The spring 47 is disposed between the swing panel 46 and the housing 41.

#In accordance with the structure mentioned above, with reference of FIG. 4, once the retractable handle 2 is pulled up, it tows the swing panel 46 which drags up the movable vertical stick 45 and the roller support 43 is swung out by the movement of the movable vertical stick 45. Simultaneously, the bottom covering plate 44 also swings out, and the back of the bottom covering plate 44 pushes the lateral covering plate 42. At this time, the roller 3 on the bottom of roller support 43 extends to the outside of luggage case 1 bottom as shown on FIG. 4. Then the luggage case could be hauled.

#While pressing the retractable handle 2, refer to FIG. 3, it drags the swing panel 46 to press the movable vertical stick 45 and make the roller support 43 retract inside so as to fold the roller 3 into the housing 41. And the bottom covering plate 44 and the lateral covering plate 42 fold at the bottom and side of the luggage case 1 respectively to make luggage case 1 looks smooth without any beetle at its outlook. Moreover, no beetles outside the surface of case make moving more easily without catch other luggage.
