BACKGROUND OF THE INVENTION
During the winter months, a pool cover is typically used to cover a swimming pool while not in use to protect the pool from leaves, dirt and any foreign matter not desired in a winterized pool. Conventionally, one or more air pillows are used to hold up the pool cover. The air pillows are formed of a rubber material filled with air. The air pillows float on the surface of the water below the pool cover for supporting the pool cover above the surface of the water. The air pillows have the disadvantage of not being durable and loosing air over time or in a worse case scenario, deflating totally. It is desirable to provide a device for supporting a pool cover providing improved support and durability.
SUMMARY OF THE INVENTION
The present invention relates to a device for supporting a pool cover including either a singular tub or a plurality of tubs coupled to one another. The tubs are a predetermined height and diameter for providing support of the pool cover. The tubs can be attached to one another in a triangle configuration. The tubs float on the surface of the water. The number of tubs can be selected to cover a predetermined area which can be larger than the area covered by conventional air pillows. The device has the advantage of being durable and unlikely to sink.
The invention will be more fully described by reference to the following drawings.

DETAILED DESCRIPTION
Reference will now be made in greater detail to a preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings and the description to refer to the same or like parts.
FIG. 1 is a top and side view of device for supporting a pool cover 10 in accordance with the teaching of the present invention. In this embodiment, a plurality of tubs 12 are coupled to one another using coupling means 14. For example, three tubs 12 can be attached to one another in a triangle configuration. Alternatively, one tub 12 or various numbers of tub 12 can be used in device 10. Device 10 is placed on water surface 13 of pool 11, as shown in FIG. 2.
Tub 12 is formed of a predetermined height and width for providing support of a pool cover at a predetermined distance from the water surface, as shown in FIG. 3A. Tub 12 can be formed of sidewall 100 integral with bottom wall 102 forming hollow cavity 104 within tub 12. For example, tub 12 can have a height of about 15 inches and a width of about 22 inches. Tub 12 shall include lip 15 at top surface 17 thereof. Tub 12 can be formed of a material to resist cracking during cold or freezing temperatures, for example, temperatures below 40° F. For example, tub 12 can be formed of a rubberized plastic. Tub 12 shall be formed of a cylindrical shape
A plurality of apertures 16 are formed in lip 15 around the circumference thereof, as shown in FIG. 3B. Connector 18 is inserted in one or more apertures 16 for attaching one or more of tubs 12 together. For example, apertures 16 can be about 0.5 inches in diameter and can be equally spaced around the circumference of lip 15.
For coupling tubs 12 in a triangular configuration, connector 18a can be inserted in aperture 16a of first tub 12a to attach to aperture 16b of second tub 12b, as shown in FIG. 4. Connector 18b can be inserted in aperture 16c of first tub 12a to attach to aperture 16d of the third tub 12c. Connector 18c can be inserted in aperture 16e of second tub 12b to attach to aperture 16f of third tub 12c.
Connector 18 can have a head 19 attached to legs 20,21, as shown in FIG. 5. Head 19 is slightly larger than the 0.5 inch diameter of apertures 16. Legs 20,21 can be inserted into apertures 16 of overlapping lips 15 of adjacent tubs 12. Alternatively, connector 18 can comprise a tie 22 for adjoining adjacent tubs 14, as shown in FIG. 4.
Apertures 30 can be formed in side surface 32 of tub 12, as shown in FIGS. 6A and 6B. For example, apertures 30 can be formed approximately in the top third of the height of side surface 32. Cord 34 is inserted into aperture 30, as shown in FIG. 7. Retaining means 36 is positioned at end 35 of cord 34 for preventing cord 34 from pulling through aperture 30, as shown in FIG. 8.
After placement of tubs 12 on water surface 13, cord 34 can be attached to pool 11, as shown in FIGS. 9A and 9B. Cord 34 can be attached using coupling means 38. For example, coupling means 38 can comprise of a hook, as shown in FIG. 10. Cord 34 can attach or be tied to coupling means 38. Cord 34 can be formed of nylon. Tubs 12 can be placed in the center of pool 11 roughly 120 degrees apart and coupled to pool 11 in this configuration in order to be equidistant from one another and provide maximum stabilization, as shown in FIG. 2.
After coupling of device 10 to pool 11, cover 40 can be attached over device 10, as shown in FIG. 11A. Cover 40 can be attached to pool 11 using conventional means, as shown in FIG. 11B.
It is to be understood that the above-described embodiments are illustrative of only a few of the many possible specific embodiments, which can represent applications of the principles of the invention. Numerous and varied other arrangements can be readily devised in accordance with these principles by those skilled in the art without departing from the spirit and scope of the invention.
