DESCRIPTION OF THE PREFERRED EMBODIMENT(S)

[0024] FIG. 1 is a perspective view of a floating structure 10, such as a swim raft, with its decking 80 partially broken away. The decking 80 is attached to a lower frame 12 that includes a plurality of joists 14, beams 16 and cross members 18. On opposite sides of the floating structure 10 are wo parallel, elongated float bodies 22. On the opposite ends of the floating structure 10 and under the lower frame 12 are two, optional short float bodies 22′

[0025] As shown in FIGS. 2-6, the elongated float bodies 22 are made of closed cell foam covered by a protective layer 45. In the embodiment shown herein, the foam is made of PVC and the protective layer 45 is made of polyurea applied by spray application. It should be understood that other types of foams and protective layers may be used.

[0026] Each float body 22 includes a round top surface 24, two straight vertical sides 26, 28 and a flat bottom surface 30 In the embodiment shown, the float body 22 measures approximately 12 inches in width, approximately 18 inches in height. The elongated float body 22 is approximately 96 inches in length. The short elongated float body 2′2 shown in FIGS. 1 and 2 is approximately 48 inches in length It should be understood both the elongated float body 22 and short float body 22′ made be made in different lengths, widths, and heights.

[0027] The top surface 24 is round, dome-shaped. In the embodiment shown in the Figs, the top surface is a continuous arc extending from opposite sides 26, 28. The top surface 24 has a radius of approximately 18 inches. As stated above, the purpose of using a round top surface, 24 is to prevent stagnant water or debris build up on the float body 22. It should be understood the top surface 24 may be other shapes, such as a beveled or conical surface that prevents debris build up.

[0028] As stated above, each float body 22, 22′ is made of closed-cell foam molded into an elongated float shape. While the sides 26, 28 and the bottom surface 30 are shown as flat surfaces and perpendicularly aligned with the adjacent surface. It should be understood these surfaces could be round or irregular shaped and aligned non-perpendicular to the adjacent surface.

[0029] A plurality of T-shaped or L-shaped brackets 50 is embedded into the top surface 24, 24′ of each float body 22, 22′, respectively. In one embodiment, the transversely aligned bracket cutouts 40 are formed in the top surface 24, 24′ of the float bodies 22, 22. The shape of bracket cutouts 40 is inverted ‘t’ shaped and complementary to the brackets 50.

[0030] In one embodiment, the bracket cutouts 40 are formed after the float body 22, 22′ are formed with, a hot wire cutter (not shown). It should also be understood that brackets 50 may be placed in the mold form and foam material is then poured into the mold form. Foam material cures around the brackets 50 to form a single float body 22 with a plurality of upward extending brackets 50 embedded into the float body 22.

[0031] After the float body 22 has been manufactured and the brackets 50 have been inserted into the bracket cutouts 40, caulking 45 is applied to the cracks between the float body 22 and the brackets 50. Polyurea coating 47 is then sprayed over the entire float body 22. When the polyurea coating 47 has hardened, it protects the float body 22 and seals and locks the brackets 50 inside the bracket cutouts 40.

[0032] As shown in FIG. 7, each bracket 50 includes a horizontal flange 52 and a perpendicularly aligned vertical flange 60. The horizontal flange 52 is a flat plate configured to extend horizontally and transversely through the upper portion of the float body 22. The vertical flange 60 is a flat plate that extends upward from the horizontal flange 52. The vertical flange 60 is approximately the same length as the horizontal flange 22 and is sufficient in width so that the upper edge of the vertical flange 60 extends above the top surface 24 of the float body 22. In the embodiment shown in the Figs, the vertical flange 60 is slightly offset from the horizontal flange's longitudinal axis 61, thereby dividing the horizontal flange 52 into a first section 54 and a second section 56. Formed on the upper portion of the vertical flange 60 are holes 62 that receive threaded connectors 70, such as a bolt. A washer 72 and nut 74 are attached to the opposite end of the threaded connector 70.

[0033] In one embodiment, a frame member void space 65 is formed on the top surface 24 of the float body 22 adjacent to the vertical flange 60. In the first embodiment, the void space 65 is formed after the float body 22 has been formed using a hot wire. It should be understood, however, that the mold space 65 could be formed in the molding process.

[0034] The void space 65 extends downward from the top surface 24 and exposes part of the first section 54 on the horizontal flange 52. The void space 65 extends transversely over the float body 22 and is sufficient in width to receive a frame member extending transversely over the float body 22. During use, threaded connectors 70 transfer forces through the vertical flange 60 onto the frame member 16 and the horizontal flange 52 transfers forces to the bottom of the frame member 16. Because the void space 65 is approximately the same width as the frame member 16, the frame member 16 becomes ‘locked’ into the float body 22.

[0035] In another embodiment, shown in FIG. 9, bracket 50 includes a modified vertical flange 60′ extending above the top 24 of the float body 22. The vertical flange 60′ fits inside a bracket cutout 40′ slot formed on the float body 22. In this embodiment, the entire horizontal flange 52′ is embedded and covered by the float body 22. A frame member 16 then extends over the top surface 24 of the float body 22 and attaches to the exposed area on the vertical flange 54′ above the top surface 24 with threaded connectors 70.

[0036] Using the above described float and bracket assembly, a floating structure shown in FIG. 1 may be constructed. As stated above, the floating structure 10 includes a lower frame 12 that includes a plurality of joists 14, beams 16 and cross members 18. Attached to the top surface of the frame 12 is decking 80. Located under the frame 12 are two elongated float bodies 22 and two short float bodies 22′. Mounted on each float body 22, 22′ are brackets 50 attached to the frame 12.

[0037] In compliance with the statute, the invention described has been described in language more or less specific as to structural, features. It should be understood however, that the invention is not limited to the specific features shown, since the means and construction shown, comprises the preferred embodiments for putting the invention into effect. The invention is therefore claimed in its forms or modifications within the legitimate and valid scope of the amended claims, appropriately interpreted under the doctrine of equivalents.
