DETAILED DESCRIPTION OF CERTAIN PREFERRED EMBODIMENTS

The present invention may be embodied in various forms. An embodiment of a submergible stool 10 is shown in FIGS. 1-2. For convenience, the terms “upper” and “lower” and “top” and “bottom” are used herein to differentiate between the upper and lower ends of submergible stool 10 and particular components of the stool. It is to be appreciated that “upper” and “lower” and “top” and “bottom” are used only for ease of description and understanding and that they are not intended to limit the possible spatial orientations of the submergible stool or its components during assembly or use.

The term “substantially”, as used herein, is meant to mean mostly, or almost the same as, within the constraints of sensible commercial engineering objectives, costs, manufacturing tolerances, and capabilities in the field of submergible stool manufacturing and use. Similarly, the term “approximately” as used herein is meant to mean close to, or about a particular value, within the constraints of sensible commercial engineering objectives, costs, manufacturing tolerances, and capabilities in the field of submergible stool manufacturing and use.

Stool 10 may include a body 11 including a top 12 and a bottom 14 spaced from top 12 and configured to rest on the bottom surface 16 of a body of water 18, such as a pool 20, for example, as seen in FIG. 2. A sidewall 22 of body 11 may extend between top 12 and bottom 14 and define an outer peripheral surface of stool 10.

Stool 10 may include a peripheral wall 24 extending around a portion of top 12 of stool 10 and defining a seat 26 upon which a user 23 may sit while stool 10 is submerged in pool 20. In the illustrated embodiment, peripheral wall 24 extends along opposed sides 28 of stool 10 and around a back or rear 30 of stool 10, leaving a front 32 of stool 10 exposed.

A recess 34 may be formed in front 32 of stool 10. Recess 34 may include a bottom surface 36 proximate bottom 14 of stool 10, a rear wall 38 extending upwardly and forwardly from a rear edge 40 of bottom surface 36, and a pair of opposed recess sidewalls 42 that extend forwardly from rear wall 38.

Bottom surface 36 of recess 34 may act as a footrest upon which user 23 may rest their feet when stool 10 is seated in pool 20. Bottom surface 36 may be sloped downwardly from rear edge 40 to a front edge 44 thereof, which may be more comfortable for the feet of user 23 when they are seated on stool 10.

As seen in FIG. 2, pool 20 may have a depth A measured from a top surface 46 of its deck 48 to its bottom surface 16, while water 18 may have a depth B within pool 20. Deck 48 may have a thickness C where it extends outwardly over water 18 in pool 20. Pool 20 may be filled such that the upper surface of water 18 is spaced from a bottom edge of deck 48 by a distance D. Stool 10 may have a height H.

In certain embodiments, depth A may be approximately 36 inches, depth B may be approximately 30 inches, thickness C may be approximately 2 inches, distance D may be approximately 4 inches, and height H may be approximately 21.5 inches. Such an embodiment illustrates an example of when the deck SS of pool 20 is positioned approximately at table height with respect to user 23 when they are seated on stool 10, as seen in FIG. 2. It is to be appreciated that stool 10 can be configured to have a different height H to accommodate being positioned at a greater depth within pool 20, as discussed in greater detail below. As illustrated in FIG. 1, stool 10 may have a width W and a depth DP. In certain embodiments, width W may be approximately 18.12 inches, and depth DP may be approximately 18.25 inches.

As seen in FIG. 3, top 12, bottom 14, and sidewall 22 may enclose and define an interior cavity 50 of stool 10. A first aperture 52 may be formed in sidewall 22 proximate bottom 14 in front 32 of stool 10, and may extend through sidewall 22 from interior cavity 50 to an exterior of stool 10. A second aperture 54 may be formed in sidewall 22 proximate top 12 in rear 30 of stool 10, and may extend through sidewall 22 from interior cavity 50 to an exterior of stool 10. In the illustrated embodiment, first aperture 52 is formed in rear wall 38 of recess 34, and second aperture 54 is formed in peripheral wall 24.

First aperture 52 and second aperture 54 are positioned and configured such that when stool 10 is placed and submerged in a body of water, like pool 20, water 18 will flow into interior cavity 50 through first aperture 52 in the direction of arrow F, and air will be forced out of second aperture 54 in the direction of arrow X. As interior cavity 50 fills with water 18 and air leaves interior cavity 50, stool 10 will sink to bottom 16 of pool 20. As illustrated in FIG. 4, stool 10 is self-righting such that as it is dropped into pool 20 and starts to submerge in the direction of arrow S, water 18 will enter and air will exit interior cavity 50, and top 12 of stool 10 will move upwardly in the direction of arrow R as seen in FIG. 4 until stool reaches the upright position illustrated in FIG. 1.

In certain embodiments, as illustrated in FIG. 3, an additional first aperture 52′ may be formed in sidewall 22 at rear 30 of stool 10 opposite first aperture 52, which may provide for additional water to flow into interior cavity 50 as stool 10 is submerged in pool 20.

In certain embodiments, as illustrated in FIG. 5, a channel 56 may be formed about a periphery of seat 26 and may be sloped downwardly from a rear 57 of seat 26 toward front 32 of stool 32 such that water may flow off of the front of seat 26 in the direction of arrows D, which may be advantageous when stool 10 is positioned on a dry surface, such as the area surrounding pool 20.

In certain embodiments, as illustrated in FIGS. 6-7, a plurality of recesses 58 may be formed in bottom 14 of stool 10, and each recess 58 may receive a leg 60. A surface of each recess 58 may include threads 62, which matingly engage threads 64 on an exterior of each leg 60. Legs 60 may provide weight to stool 10 proximate bottom 14, thereby helping maintain stool 10 in its upright position when it is seated in pool 20, and may help right stool 10 when it is dropped into pool 20. In the illustrated embodiment, four recesses 58 are formed in bottom 14 of stool 10, with mating legs 60 being received in each of the four recesses 58. It is to be appreciated that any desired number of recesses 58 and mating legs 60 can be provided for stool 10.

Each leg 60 may include a weight 66 seated in a cover 68, with threads 64 being formed on an exterior of cover 68. A cap 70 may be secured to an open top end 72 of cover 68, sealing insert 66 within a cavity 73 formed in cover 68. Cap 70 and foot 78 may be formed of a plastic or elastomer, e.g., nylon, and cap 70 may be secured to foot 78 by sonic welding or other suitable means. A bottom surface 80 of each foot 78 may include a slot 82 into which a tool, for example, a proprietary tool or a flat-head screwdriver, may be inserted in order to more easily turn foot 78 and position leg 60 at a desired height with respect to stool 10.

In certain embodiments, weight 66 may be a cylindrical rod, and may be formed of metal, such as steel, for example. In certain embodiments, each weight 66 may weigh approximately 2 lbs. It is to be appreciated that weight 66 may be formed of any type of material, and may have any desired weight. By positioning weights 66 in legs 60, the lower portion of stool 10 will weigh more than the upper portion of stool 10, thereby helping stool 10 right itself to an upright condition when it is dropped in pool 20.

Bottom 14 of stool 10 may include A cleanout port 67 may extend through bottom from interior cavity 50 to an exterior of stool 10, and may be used to clean out manufacturing debris, for example, in a post-molding process while stool 10 is being formed. A port plug 69 may be received in cleanout port 67. In certain embodiments, port plug 69 may be permanently secured within cleanout port, such as with an adhesive, for example.

By providing threads on legs 60, the legs 60 can be positioned at different heights, as illustrated in FIG. 8, to accommodate for differences in the slope of bottom 16 of pool 20, thereby allowing stool 10 to be positioned in an upright position even when bottom 16 does not extend horizontally. As seen in FIG. 8, where bottom 16 of pool 20 is sloped at angle P, two of the legs 60 are visible, with the leftmost leg 60 seen here extended to a first distance L, and the rightmost leg 60 extended a greater distance R.

Another embodiment of a stool 10A is illustrated in FIG. 9. Stool 10A is configured with a greater height H than that of stool 10 illustrated in FIGS. 1-3 in order to accommodate being positioned in pool 20 with a greater depth of water 18. Stool 10A, for example, may have a height HA of approximately 33 inches. Such an embodiment illustrates an example of when the deck 48 of pool 20 is positioned approximately at bar height with respect to user 23 when they are seated on stool 10A.

Stool 10A may be configured such that bottom surface 36 of recess 34 is spaced upwardly from bottom 14 of stool 10A by a distance N. Stool 10A may include a shelf 84 positioned between sidewalls 42, with bottom surface 36 of recess 34 defining the top surface of shelf 84. A bottom recess 86 may be formed in stool 10A beneath shelf 84, with first aperture 52 being formed within recess 86 proximate bottom 14 of stool 10A.

Another embodiment of stool 10 is shown in FIG. 10, in which seat 26 and bottom surface 36 of recess 34 are textured. It is to be appreciated that a textured surface may be formed on seat 26 and bottom surface during manufacture of stool 10. In other embodiments, a first textured sheet 88 may be secured to seat 26 and a second textured sheet 90 may be secured to bottom surface 36. First textured sheet 88 may be secured to seat 26 and second textured sheet 90 may be secured to bottom surface 36 with an adhesive, for example.

An alternative embodiment of cover 68 for leg 60 is illustrated in FIGS. 11-12. In this embodiment, a plurality of thread clips 92 are positioned along threads 64 of cover 68. Thread clips 92 may help ensure a tight tolerance fit with threads 62 of recesses 58 in stool while reducing surface area contact. Such a configuration can help provide a tight fit while providing for smooth assembly of legs 60 with stool 10 by the user. Thread clips 92 may be substantially U-shaped projections extending outwardly from threads 64, and may be formed integrally with threads 64 when cover 68 is formed such that threads 64 and thread clips 92 are of unitary, one-piece construction. In other embodiments, thread claims 92 may be separate elements that engage threads 64 in a snap-fit or interference fit, or may be secure to threads 64 with adhesive, for example. Thread clips 92 and cover 68 with threads 64 may be formed of acrylonitrile styrene acrylate (“ASA”), or injection molded plastic, for example. In certain embodiments, thread clips 92 may be positioned at 90° intervals about cover 68 on every other thread 64.

Another embodiment of a stool 10B is illustrated in FIG. 13, in which an upper cavity 94 may be formed in stool 10B. Upper cavity 94 may be positioned proximate top 12 of stool and may be positioned within peripheral wall 24. A plurality of inserts 96 may be received in upper cavity 94. Inserts 96 may be formed of a lightweight material, which is lighter than the material used to form stool 10B, and serve to help stool 10B right itself when submerged in water. By having lightweight inserts 96 seated in cavity 94, the upper portion of stool 10B will weigh less than the lower portion of stool 10B, thereby helping stool 10B right itself to an upright condition when it is dropped in pool 20. Inserts 96 may be formed of Styrofoam, for example. Other suitable materials for inserts 96 will become readily apparent to those skilled in the art, given the benefit of this disclosure.

Although first apertures 52, 52′ and second aperture 54 are not visible here, it is to be appreciated that this embodiment of stool 10B may include such apertures, which may help stool 10B right itself when submerged in pool 20. Further, it is to be appreciated that the additional embodiments of stool 10 described below, some of which are shown in schematic fashion, also may include such apertures even though such apertures are not visible in the drawings provided below.

Another embodiment of a stool 10C is illustrated in FIG. 14, in which a lower cavity 98 may be formed in stool 10C. Lower cavity 98 may be positioned proximate bottom 14 of stool 10C. A plurality of weights 66A may be received in lower cavity 98. Weights 66A may be formed of a material that is heavier than the material used to form stool 10B, and serve to help stool 12C right itself when submerged in water. By having weights 66A seated in cavity 98, the lower portion of stool 12B will weigh more than the upper portion of stool 12C, thereby helping stool 12C right itself to an upright condition when it is dropped in pool 20. Weights 66A may be sand, gravel, cement, ball bearings, or any other material that would provide for additional weight within lover cavity 98. Other suitable material for weights 66A will become readily apparent to those skilled in the art, given the benefit of this disclosure.

Another embodiment of a stool 10D is illustrated in FIGS. 15-16, and may include a body 11A defined by sidewall 22, and a base 104 spaced from body 11A. In such an embodiment, a bottom surface of base 104 defines bottom 14 of stool 10D. A weight 66B may be seated in a recess 106 formed in a top surface of base 104. Weight 66B may be a cylindrical disk and may be formed of metal, for example, and helps provide additional weight to a lower portion of stool 10D, thereby helping ensure that stool 10D rights itself to an upright position when it is submerged in water.

Base 104 may be adjustably secured to body 11A by a plurality of legs 60A extending between base 104 and body 11A. Legs 60A may be threaded rods 106 that allow for base 104 to be adjusted or angled with respect to body 11A, thereby allowing body 11A of stool 10D to be vertically aligned when bottom 14 is seated on a sloped or inclined bottom 16 of pool 20.

Legs 60A may extend through threaded female inserts 108 seated in the bottom of cavities 110 formed in a bottom of body 11A, such that upper ends 112 of legs 60A are received in cavities 110. Lower ends 114 of legs 60A may be received by pivotable knobs 116 that are seated in cavities 118 formed in base 104. Cavities 118 may have a reduced thickness neck 120 in a central portion thereof, which prevents knobs 116 from moving upwardly through cavities 118. By adjusting legs 60A to different heights, as seen in FIG. 16, the user can ensure that body 11A of stool 10D is vertically aligned when bottom 16 of pool 20 is sloped or inclined.

Another embodiment of a stool 10E is illustrated in FIGS. 17-18, and may include a body 11B defined by sidewall 22. A plurality of adjustable legs 60B may extend downwardly from bottom 14 of body 11B of stool 10E. In the illustrated embodiment four legs 60B are positioned about bottom 14. However, it is to be appreciated that any number of legs 60B can be positioned about bottom 14.

Each leg 60B may be telescopically received in a leg housing 122 secured to bottom 14 of stool 10E. Legs 60B may be hollow cylindrical members, and may be formed of metal, e.g., aluminum. A plurality of apertures 124 may extend in a row along each leg 60B. A retractable button 126 on each leg housing 122 may be selectively received in one of apertures 124 in leg 60B as leg 60B is moved upwardly or downwardly and telescopingly received in leg housing 122. An upper end 128 of each leg 60B may be received in a cavity 130 formed in bottom 14 of stool 10E as leg 60B moves upwardly and downwardly with respect to leg housing 122. As seen in FIG. 18, by adjusting the heights of legs 60B, body 11B of stool 10E can be maintained in an upright vertical position when legs 60B are seated on an inclined or sloped bottom 16 of pool 20.

A recess 132 may be formed in a central portion of bottom 14 of body 11B, and may serve to receive a weight 66C. A net 136 may be suspended beneath recess 132, and may serve to retain weight 66C within recess 132. Net 136 may be formed of a flexible, stretchable material such as silicone, for example, which allows a user to easily insert and remove weight 66C. Net 136 may be suspended from posts 138 extending outwardly from bottom 14 around recess 132. Weight 66C may have any desired configuration such as a bag filled with sand or ball bearings, or a weighted disc, for example. The use of weight 66C may allow the lower portion of stool 10E to weigh more than the upper portion of stool 10E, thereby helping stool 10E right itself to an upright condition when it is dropped in pool 20.

A tread 140 may be secured to the bottom of each leg 60B to provide grip and traction on bottom 16 of pool 20. Tread 140 may be formed of rubber or any other suitable soft and pliable material that can provide grip and traction for leg 60B on bottom 16.

Another embodiment of a stool 10F is illustrated in FIGS. 19-20, and may include a body 11C defined by sidewall 22. A base 104A may be secured to body 11C by way of a projection 144 extending upwardly from base 104A that is received in a mating recess 146 formed in a bottom of body 11C. Projection 144 and recess 146 may engage one another in a press-fit or interference manner so as to secure base 104A to body 11C. It is to be appreciated that in other embodiments projection 144 could be formed on body 11C and recess 146 could be formed in base 104A.

Base 104A may be formed of a flexible and pliable material, such as silicone, for example, that allows its bottom 14 to be altered to adapt to inclined or sloped bottom 16 of pool 20. A weight 66D may be received in base 104A, and may serve to allow the lower portion of stool 10F to weigh more than the upper portion of stool 10F, thereby helping stool 10F right itself to an upright condition when it is dropped in pool 20. Weight 66D may be sand, for example, which can easily conform to the changing shape of the bottom 14. As seen in FIG. 20, when bottom 16 of pool 20 is sloped or inclined, bottom 14 of base 104A can shift and conform to mate with the sloped surface of bottom 16, thereby helping ensure that body 11C of stool 12F maintains its upright vertical position.

In certain embodiments, as illustrated in FIG. 21, second aperture 54 may be spaced downwardly from a top of peripheral wall 24 such that when water 18 fills interior cavity a pocket 150 of air will be trapped beneath top 12 and peripheral wall 24 of stool 10, which will make the upper portion of stool 10 weigh less than the lower portion of stool 1, 0 thereby helping stool 10 right itself to an upright condition when it is dropped in pool 20.

Another embodiment of a stool 10G is illustrated in FIGS. 22-23, with stool 10G including a body 11D and a base 104B positioned below body 11D.
