FIELD OF THE INVENTION  
         [0001]    The present invention relates to a safe suitcase which can prevent possible safety accidents caused by carelessness when a cart pedestrian passes by terminals, airports, general footways or other sites crowded with people and cars while drawing a bag that is equipped with wheels and filled with clothes, his or her belongings and so on at night, by enabling general pedestrians, people riding on bicycles, or drivers of motorcycles or cars around the cart pedestrian to easily distinguish the cart pedestrian by the brilliant luminescence of the wheels.  
         BACKGROUND OF THE RELATED ART  
         [0002]    When one goes to terminals or airports for traveling with carrying a cart loaded with a suitcase fully filled with clothes, one&#39;s belongings and the like, one may pass by quiet places with less people or some crowded places mixed with pedestrians, riders of bicycles, motorcycles or cars or go across a crosswalk.  
           [0003]    Particularly, when passing by such a crowded place at night while drawing a cart on which a suitcase is rested, other pedestrians, riders of bicycles, or drivers of motorcycles or cars cannot easily distinguish the cart pedestrian, resulting in a high probability of the occurrence of safe accidents caused by carelessness. Therefore, when walking down or crossing a crosswalk while drawing a cart bag, the cart pedestrian needs to more look around considering the safe walking of other pedestrians and the danger of traffic accidents.  
           [0004]    The carts using bright color frames like an aluminum having high light reflectivity or being colored for a better discrimination at night have a limitation in securing a safe walking at night. Therefore, it is necessary to find out a way to securing the safe walking of cart pedestrians at night.  
           [0005]    In the meanwhile, some of general suitcases (including a knapsack) have wheels, but these wheels are only for a convenient moving and thus cannot be distinguished at night or at dark basements.  
           [0006]    In addition, a personal cart made of aluminum has an advantage of convenience but also has a limitation in that it cannot be easily distinguished at night or at the places, such as basements and cannot be shouldered.  
           [0007]    That is, a personal cart can carry hand luggage or rather heavier load but it itself cannot be shouldered.  
           [0008]    Thus, carts cannot be used at uneven roads or raised spots, particularly when passing by steps or slopes.  
           [0009]    As described above, it is impossible to carry heavy loads with the use of conventional carts at the places where personal carts cannot be used due to the limitation of the landform.  
         SUMMARY OF THE INVENTION  
         [0010]    Accordingly, an object of the present invention is to provide a safe suitcase which can prevent accidents caused by carelessness when a cart pedestrian passes by terminals, airports, general footways or the other sites crowded with people and cars while drawing a bag that is equipped with wheels and filled with clothes, his or her belongings and so on at night, by enabling general pedestrians, people riding on bicycles, or drivers of motorcycles or cars around the cart pedestrian to easily distinguish the cart pedestrian by the brilliant luminescence of the wheels.  
           [0011]    The above object can be obtained by the safe suitcase of the present invention wherein if a cart pedestrian uses shoulder straps after resting a suitcase having shoulder straps on a platform and retracting pulling rods, it is possible to carry heavy load more easily, and in the case of drawing the cart, the LEDs mounted on the coil box are conducted when coil terminals of the coil box in luminous wheels mounted at both sides of the strut side of the platform pass by corresponding parts of a mobile magnetic fixed to a wheel axle and thus emit brilliant lights, enabling a safe walking of a cart pedestrian in crowded places with an easy notice by general pedestrians, riders of bicycles, or drivers of motorcycles or cars.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       [0021]    In FIG. 1, a cart A applied to a safe suitcase of the present invention comprises a platform  1 , struts  2 , a central frame  2   a , pulling rods  3  having a handle  4 , legs  6  for rear support of the platform  1 , upper and lower fixing plates  7 , and fixing holes  7   a  and  7   b  for a suitcase. Luminous wheels  5  having a mobile magnetic, a coil box, a coil and LEDs (Light Emission Diode) are mounted at both sides of the central frame  2   a  of the cart A.  
         [0022]    In FIG. 2, the luminous wheels  5  emit lights from the inside thereof when they are rolled. That is, the luminous wheel  5  has bushings  8  which are respectively inserted to the extent obtained by dividing a wheel axis (not shown) into two for its convenience, bearings  9  which are respectively inserted to the bushings  8 , a mobile magnetic  10  which is tightly fixed to the front ends of the bushings  8  which passed through the bearings  9 , a coil box  11  which has a coil  12  for power generation on its inner circumference and a plurality of LEDs  13  on its outer circumference, and a tire made of hard transparent resin which is combined with the outside of the coil box  11 .  
         [0023]    The mobile magnetic  10  is of doughnut shape and is made by inserting a doughnut-shaped magnetic into a tube-shaped sleeve  14  at its center. The sleeve  14  is closely inserted to the bushings  8 , and is grounded when the cart is moved in a fixed state of the sleeve  14  to the wheel axle in the wheel  5 , and the LEDs  13  are lighted by connecting/disconnecting the positive (+) and negative (−) electrodes of the coil box  11  which is rotated according to the rotating tire.  
         [0024]    The coil  12  is placed at a core which is formed in a zigzag-shape in an inner circumference of the nonconductor coil box  11 , and plays an important role of lighting the LEDs  13  by minute currents generated according to a private power generation principle when it is rotating around the mobile magnetic  10 .  
         [0025]    The plurality of LEDs  13  have different luminous colors, and thereby it is possible to focus the eyes of night pedestrians and drivers in an instant.  
         [0026]    Referring to FIGS. 3 and 4, firstly, the bearings  9  are inserted to both bushings  8 , the mobile magnetic  10  is loosely inserted to the center of the coil box  11  assembled with the coil  12  and the LEDs  13 , and then the mobile magnetic  10  is inserted to the bushing  8 .  
         [0027]    Next, the other side of the mobile magnetic  10  is inserted to the other bushing  8  to which the other bearing  9  is inserted and a pressure is applied to the direction of the axle to make the mobile magnetic  10  not be moved on the bushings  8 . The mobile magnetic  10  fixed to the bushings  8  are mounted in a wheel molding, and a tire  15  is molded by injecting the transparent resin.  
         [0028]    If the tire  15  is molded as described above, the outer rings of the bearings  9  and the coil box  11  including the LEDs  13  are filled in the tire  15  and thus are united to the tire  15 , while the inner rings of the bearings  9  and the bushings  8  are separated from the tire  15 .  
         [0029]    When the cart A having the luminous wheels  5  as described above is pulled, the tire  15 , the coil box  11  and the LEDs  13  are rolled as it is pulled. At this time, the coil  12  is rotated around the mobile magnetic  10  to generate the positive (+) and negative (−) electrodes of the coil box  11  and thereby the LEDs  13  respectively connected to the positive and negative electrodes are lighted.  
         [0030]    The brilliant lights from the LEDs  13  are projected to the transparent tire. Thus, it works its prominent function in that the cart is easily noticed by other pedestrians or drivers of bicycles, motorcycles or cars when the cart pedestrian passes by the place requiring a special attention for a safe pedestrian due to the crowded people and cars, such as terminals, airports, hotels and markets especially at night and the place like dark underground parking lots even in the daytime, thus avoiding the collision.  
         [0031]    Therefore, it is possible to safely pull the cart A loaded with a suitcase even at night and at dark places.  
         [0032]    In FIG. 5, a suitcase  20  to which shoulder straps  21  are attached is suitable to the cart A. A band  22  the upper and lower ends of which are opened is attached to the front side of the suitcase  20  to cover the struts  2 , thereby enabling the suitcase  20  to be stably fixed to the cart A.  
         [0033]    The upper and lower ends of the shoulder straps  21  are respectively fixed to the upper and lower ends of the front side of the suitcase  20  at both sides of a pad sheet  22  for protecting the back.  
         [0034]    In FIG. 6, the bottom of the suitcase  20  is made of a box-shaped frame  23  of hard synthetic resin, and attaching holes corresponding to the fixing holes  7   a  and  7   b  are formed at the bottom of the frame  23 .  
         [0035]    The cart A and the suitcase  20  are united by corresponding the attaching holes to the fixing holes  7   a  and  7   b  of the platform  1  and then fixing them by a rivet  24  for settling the suitcase  20 .  
         [0036]    In FIG. 7, when a cart user goes to the places where it is difficult to pull the cart A loaded with the suitcase  20 , for example, slopes, steps or mountains or when the cart user uses buses, air planes, subways or trains, the cart user can move more conveniently by using the shoulder straps  21 .  
         [0037]    In FIG. 8, in normal times, the cart user pulls the cart A after extending the pulling rods  23  from the struts  2  to the extent suitable to his or her height.  
         [0038]    As described above, the present invention is advantageous in that when the cart is pulled, especially at night with heavy suicases, brilliant lights are flashed from the luminous wheels and it can be easily noticed by other people, enabling safe pedestrian and safe driving.  
         [0039]    Further, when it is impossible to pull the cart loaded with the suitcase, for example, at the slopes, mountains, uneven roads, trains, air plains or other sites, it can be conveniently moved by being shouldered.
