A bag mounted with casters has a bag body attached to a base frame mounted with the casters at four corners of a bottom surface thereof. The base frame includes a loading table, and vertically extensible rods with a grip mounted at upper ends thereof. The extensible rods are fixed on one side of the loading table so as to stand on their own. Further, when the grip is raised, the extensible rods are curved or tilted so that the grip moves toward the middle of the loading table. The extensible rods are secured at a position in a retracted state by stoppers so that the grip is positioned at an upper portion of the bag body or above the bag body, and are secured at a position by the stoppers in an extended state so that a height of the grip from the bottoms of the casters is in a range of 60 to 100 cm.

What is claimed is: 1. A mobile bag comprising: a base frame including a rectangular loading table, reinforcing walls extending perpendicularly from the short ends of the rectangular loading table, a plurality of casters mounted on a lower surface of the rectangular loading table to permit free movement on a horizontal plane in any moving direction, extensible rods upwardly extending from one side of the rectangular loading table and fixed to the reinforcing walls, respectively, so as to stand on their own, and stoppers securing the extensible rods at an extended position and a retracted position, wherein the extensible rods have a grip disposed on upper ends thereof, and the casters are mounted near the four corners of the rectangular loading table; and a bag body fixed on side surfaces of the extensible rods on or above the rectangular loading table, wherein: the extensible rods are shaped so that the grip moves from the one side of the rectangular loading table, on which the extensible rods are fixed, toward the middle of the loading table as the grip is raised by extending the extensible rods, the extensible rods are secured in a retracted state by the stoppers so that the grip is positioned at an upper portion of the bag body or above the bag body, and the extensible rods are secured in an extended state by the stoppers so that a height of the grip from the bottoms of the casters is in a range of 60 to 100 cm, and the rectangular loading table is reinforced by the reinforcing walls which stand substantially perpendicular to the surface of the loading table and adjacent to the extensible rods. 2. The mobile bag according to claim 1 wherein the extensible rods are curved so that the grip moves from the one side of the loading table, on which the extensible rods are fixed, toward the middle of the loading table as the grip is raised by extending the extensible rods. 3. The mobile bag according to claim 1 wherein the extensible rods are connected to the loading table so as to be tilted so that the grip moves from the one side of the loading table, on which the extensible rods are fixed, toward the middle of the loading table as the grip is raised by extending the extensible rods. 4. The mobile bag according to claim 1 wherein, when the extensible rods are fully extended, the grip is positioned over the loading table in a range of 15 to 80% when an end surface of the one side on which the extensible rods are fixed, is defined as a zero point, and an end surface of the opposite side is defined 100%. 5. The mobile bag according to claim 1 wherein, when the extensible rods are fully extended, the grip is located in a position over the loading table in a range of 20 to 60% when an end surface of the one side on which the extensible rods are fixed, is defined as a zero point, and an end surface of the opposite side is defined 100%. 6. The mobile bag according to claim 1 wherein, when the extensible rods are fully extended, the grip is located in a position over the loading table in a range of 20 to 50% when an end surface of the one side on which the extensible rods are fixed, is defined as a zero point, and an end surface of the opposite side is defined 100%. 7. The mobile bag according to claim 1 wherein the bag body is made of a flexible sheet by sewing, and the bag body is detachably attached to the base frame. 8. The mobile bag according to claim 1 wherein the extensible rods include guide tubes, which vertically extend from and are fixed on the loading table, and sliding rods, which are inserted into the guide tubes so as to be telescoping, and the grip is fixed at upper ends of the sliding rods. 9. The mobile bag according to claim 8 wherein the stopper includes a projecting pin disposed at a lower end portion of the sliding rod so as to elastically project toward the guide tube, receiving portions provided on the guide tube for receiving the projecting pin therein, and a disengagement mechanism for forcedly disengaging the projecting pin from the receiving portions. 10. The mobile bag according to claim 9 wherein the disengagement mechanism includes a push button disposed on the grip, a drive rod installed inside the grip and the sliding rod so as to be vertically movable by operation of the push button, and a pivot member for forcedly moving the projecting pin inward upon being pushed by the drive rod. 11. The mobile bag according to claim 10 wherein the push button is disposed on an upper surface of the grip. 12. The mobile bag according to claim 1 wherein two extensible rods are fixed on the one side of the loading table, and the grip is connected to the upper ends of the two extensible rods. 13. The mobile bag according to claim 12 wherein each of the two extensible rods includes a guide tube and a sliding rod, and a connecting rod is connected between upper ends of the guide tubes. 14. The mobile bag according to claim 13 wherein the two extensible rods are fixed at both end portions of the one side of the loading table. 15. The mobile bag according to claim 1 wherein the bag body is attached to an area surrounded by the reinforcing walls and the extensible rods. 16. The mobile bag according to claim 15 wherein the base frame is integrally formed with the loading table and the reinforcing walls of a plastic material. 17. The bag mounted with casters according to claim 1 wherein the loading table includes projecting portions projecting in the direction that extends along the width of the loading table at side portions thereof on which the extensible rods are fixed, wherein two of the casters are fixed to portions where the projecting portions are provided. 18. The mobile bag according to claim 1 wherein a collapsible chair is connected to the extensible rods. 19. The mobile bag according to claim 18 wherein the collapsible chair includes a seat connected to the extensible rods so that one side portion of the seat can tiltaby and vertically move, a folding leg tiltably connected to a connecting portion of the seat, a support link connected to the folding leg so as to keep the seat in a horizontal position, and a connecting link for restricting a tilted angle of the folding leg. 20. The mobile bag according to claim 1 wherein the reinforcing walls increase in height in a direction toward the extensible rods to provide a more rigid structure.
