BACKGROUND OF THE INVENTION [0001]1) Field of the Invention [0002]This invention relates to a float structure, specifically a float structure of a simple arrangement with a hollow cavity that is capable of being stacked and connectively assembled. [0003]2) Description of the Related Art [0004]Many float patents are presented under the Taiwan Patent Bulletin numbers 254801, 259076, 259077, 260135, 287513, 315829, 329080, 370072, 370958, and 358452. Said float patents generally disclose an identical type of hollow cavity float structure, but the float-to-float connective means consists of a tab disposed at the four corners of each float, with a mounting hole in each tab, such that when the tabs of two floats are stacked one above the other, their mounting holes aligned, a fastening rod is inserted through the two stacked mounting holes to thereby enable the coupling of the two floats; while such float structures are admittedly practical, the hollow cavities are excessively large, thereby providing a floatation magnitude of a greater degree even though the tabs at the corners are relatively thin and, as a result, as the float is subjected to center-of-pressure stress to the extent that the tabs are driven apart due the moment of force exerted, the connective stability of the floats is less than optimal; furthermore, such floats are more suited for horizontal connection and although they may be in an upper and lower connective arrangement, this is achieved by the insertion of a cord from top to bottom through the float tabs, however, since the cord is typically of a small diameter and the tab mounting holes are larger (since they originally provide for the insertion of fastening rods), following upper and lower routing and given the in-water forces of floatation, shifting instability is even higher; therefore, the prior art awaits substantial improvement. SUMMARY OF THE INVENTION [0005]The objective of this invention is to provide an improved float structure comprised of a cavitary body consisting of a hollow internal section, said cavitary body having disposed on it a first conjoinment structure and a second conjoinment structure; when two floats are stacked into an assemblage, the first conjoinment structure of the rear float is inserted into the second conjoinment structure of the front float to thereby enable the connective assembly of the two floats.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0019]In the detailed description of the preferred embodiments, it should be noted that similar elements are indicated by the same reference numerals throughout the disclosure. [0020]Referring to FIG. 1, FIG. 2, and FIG. 3, the first preferred embodiment float 1 of the invention herein is comprised of a cavitary body 11 having a generally rectangular shape and in which the hollow internal aspect is extruded from a plastic pliant material, a raised seat 12 disposed at the upper extent of the cavitary body 11, affording thereby two raised seats 12, with each raised seat 12 of an octagonal shape; a recessed seat 13 disposed at the lower extent of the cavitary body 11 such that it serves as a second conjoinment structure aligned vertically with said raised seat 12, each recessed seat 13 of an octagonal shape and each recessed seat 13 having an indentation 131; a plurality of tubular entities 14 disposed through the cavitary body 11, with a passage 141 formed in each tubular entity 14, one end at the upper aspect of each passage 141 in continuity with the raised seat 12 and the other end in continuity with the indentation 131 at the lower extent of the recessed seat 13; a shoulder section 132 formed at the bottom portion of each indention because the diameter of the passage 141 is smaller than the width of the recessed seat 13 indentation 131; and a shallow trough 15 disposed laterally from top to bottom around the cavitary body 11.
