DETAILED DESCRIPTION OF THE INVENTION

[0012] With reference to FIGS. 1 to 7, the carrier for rolling balls of the invention is illustrated. The invention includes the following elements.

[0013] A plate body 10 includes an upper plate 20 and a lower plate 30. The upper plate 20 is formed with a plurality of through holes 21. The lower plate 30 is fixed to a lower side of the upper plate 20 and has a shape corresponding to that of the upper plate 20. The lower plate 30 has a plurality of through holes 31 which are positioned corresponding to the through holes 21 of the upper plate 20.

[0014] A plurality of balls 40 are loosely embedded into the through holes 21, 31 of the upper plate 20 and the lower plate 30. One of through holes 21 of the upper plate 20 and a corresponding one of the through holes 31 of the lower plate 30 are located with a respect one of the balls 40. The balls 40 are rotatable within the through holes. A diameter of the ball 30 is larger than the summation of a width of the upper plate 20 and a width of the lower plate 30, and an upper end of the ball 40 protrudes from an upper side of the upper plate 20, and a lower end of the ball 40 also protrudes from a lower side of the lower plate 30. Therefore, when the plate body 10 is placed on a surface, it is rollable along the surface. As illustrated in FIG. 6, if a plurality of heavy objects 1 are placed on the plate body 10, the balls 40 will support the heavy objects 1 and thus the heavy objects I are slidable along the balls 40.

[0015] In the invention, the balls 40, the upper plate 20 and the lower plate 30 are made of steel.

[0016] The number and sizes of the balls 40 are adjustable based on the objects supported thereby.

[0017] In the invention, the forms of the upper plate 20 and lower plate 30 may be different. In FIGS. 1 to 3, the upper plate 20 and lower plate 30 have rectangular shapes. However, this shape is not used to confine the scope of the invention, they may have other shapes, such as triangular shapes, round shapes, etc. All these shapes are within the scope of the invention. The upper plate 20 and lower plate 30 are formed with locking holes 50 for receiving screws 51 so as to fix the upper plate 20 to the lower plate 30. The ways for fixing the upper plate 20 with the lower plate 30 are not confined to above said. All other ways which could fix the upper plate 20 with the lower plate 30 are within the scope of the invention.

[0018] With reference to FIG. 4, the invention further comprises a bottom plate 60 which has a smooth upper surface and is located below the lower plate 30. If the lower plate 30 is placed on a coarse surface. The bottom plate 60 will contact the coarse surface so that the bottom plate 60 may roll on the bottom plate 60 for preventing the bottom plate 60 from motionlessness on the coarse surface. The bottom plate 60 may be a steel plate.

[0019] Referring to FIG. 5, the invention further comprises a top plate 70 which has a smooth upper surface. When a heavy object is placed on the top plate, the heavy object may be steadily located on the plate body 10. The top plate may be a steel plate.

[0020] The invention serves to place a heavy object on the balls 40 in the plate body 10. The weight of the heavy object may be several tens tons. If it is necessary to fine-adjust the location of the heavy object, since in the invention, the balls 40 are on the lower side of the heavy object, and thus the heavy object may be moved slightly with a slight force. Referring to FIG. 6, a plurality of plate bodies 10 are arranged on the four corners of the heavy object 1. Therefore, only slight force is used to move the heavy object, while the conventional way cannot achieve this object.

[0021] With reference to FIG. 7, a jack 80 is arranged on the upper side of the plate body 10 for supporting a heavy object 1. The jack 1 may lift or descent the heavy object 1, while the plate body 10 may horizontally move the heavy object 1 so that the object can be deposited 3 dimensionally.

[0022] The invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
