Benefits of technology

[0006] In another preferred embodiment, the plastic core is ribbed to provide increased load bearing capabilities. The ribs improve the static load capabilities of the cover, and resist sagging. A foam or similar material may be injected between the ribs to enhance the thermal properties of the cover.
[0007] The present invention provides several advantages. First, the cover resists filling with water, avoiding the growth and weight problems associated with such water. Second, the core cannot become waterlogged. Third, the cover supports significantly increased weight, and therefore reduces the likelihood that a child with break the cover. Fourth, the cover provides water run off from its sloped upper surface; and the cover does not sag.

Problems solved by technology

Third, the cover supports significantly increased weight, and therefore reduces the likelihood that a child with break the cover.

Embodiment Construction

[0013] A hot tub in accordance with the preferred embodiment is shown in FIG. 1 and generally designated 10. It should be understood that the hot tub 10 may be rectangular (as shown) or any other desired shape. The cover 12 fits over the entire opening 11 of the hot tub 10. The cover 12 generally includes a vinyl jacket 14 and a plastic core insert 16. The vinyl jacket 14 encloses the core 16 and is conventionally sealed around the core 16. The core insert 16 includes a hinge 22 that allows the cover 12 to fold onto itself. The core insert 16 tapers from the hinge towards the periphery and includes a plurality of strengthening ribs 18.

[0014] The jacket 14 is well known and generally made of a marine grade vinyl, or another high-strength waterproof fabric. The jacket 14 is large enough to fit over a rigid core 16, and includes a front edge 24, rear edge 26, and an outer edge 28. In a preferred embodiment, the jacket 14 is capable of being sealed to completely enclose the core 16 by ...

Abstract

A hot tub cover having a structural, non-water absorbing, plastic core and a jacket enclosing said core. The core includes two identical core halves hinged to one another. Each core half includes an upper wall, a lower wall, and a plurality of ribs extending therebetween. The upper wall of each half slopes downwardly from the center to the peripheral edge.

Description

BACKGROUND OF THE INVENTION [0001] The present invention relates to a cover for spas, hot tubs, and the like and more particularly to an improved core for such covers. [0002] In order to provide insulation, limit pollution, and prevent the risk of accidents, it is desirable to cover the open top of a spa or hot tub. A conventional cover typically includes a foam material that is covered with fabric. These conventional covers are generally designed to cover the entire open surface of a hot tub, often having two separate halves capable of folding together to aid in removal of the cover. [0003] Conventional hot tub covers have several disadvantages. First, the cover can become filled with water by a leak or other means, causing the cover to be excessively heavy. When this happens, the weight of the cover is greatly increased and removal becomes extremely burdensome. Second, in extreme cases, the foam core can become waterlogged, leading to interior bacterial growth and or weakening of ...
