[0064] The terms coupled and connected, along with their derivatives, may be used. It should be understood that these terms are not intended as synonyms for each other. Rather, in particular embodiments, connected may be used to indicate that two or more elements are in direct physical or electrical contact with each other. Coupled may mean that two or more elements are in direct physical or electrical contact (e.g., directly coupled). However, coupled may also mean that two or more elements are not in direct contact with each other, but yet still cooperate or interact with each other (e.g., indirectly coupled).

[0065] The term water-containing structure (or structure for short) includes, but is not limited to, pools (commercial and private), spas, hydrotherapy vessels, and tubs in which a person is to be immersed.

[0066] For the purposes of the description, a phrase in the form A/B or in the form A and/or B or in the form at least one of A and B means (A), (B), or (A and B), where A and B are variables indicating a particular object or attribute. When used, this phrase is intended to and is hereby defined as a choice of A or B or both A and B, which is similar to the phrase and/or. Where more than two variables are present in such a phrase, this phrase is hereby defined as including only one of the variables, any one of the variables, any combination of any of the variables, and all of the variables, for example, a phrase in the form at least one of A, B, and C means (A), (B), (C), (A and B), (A and C), (B and C), or (A, B and C).

[0067] Relational terms such as first and second, top and bottom, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. The description may use perspective-based descriptions such as up/down, back/front, top/bottom, and proximal/distal. Such descriptions are merely used to facilitate the discussion and are not intended to restrict the application of disclosed embodiments. Various operations may be described as multiple discrete operations in turn, in a manner that may be helpful in understanding embodiments; however, the order of description should not be construed to imply that these operations are order dependent.

[0068] As used herein, the term about or approximately applies to all numeric values, whether or not explicitly indicated. These terms generally refer to a range of numbers that one of skill in the art would consider equivalent to the recited values (i.e., having the same function or result). In many instances these terms may include numbers that are rounded to the nearest significant figure. As used herein, the terms substantial and substantially means, when comparing various parts to one another, that the parts being compared are equal to or are so close enough in dimension that one skill in the art would consider the same. Substantial and substantially, as used herein, are not limited to a single dimension and specifically include a range of values for those parts being compared. The range of values, both above and below (e.g., +/ or greater/lesser or larger/smaller), includes a variance that one skilled in the art would know to be a reasonable tolerance for the parts mentioned.

[0069] It will be appreciated that embodiments of the systems, apparatuses, and methods described herein may be comprised of one or more conventional processors and unique stored program instructions that control the one or more processors to implement, in conjunction with certain non-processor circuits and other elements, some, most, or all of the functions of the systems, apparatuses, and methods described herein. The non-processor circuits may include, but are not limited to, signal drivers, clock circuits, power source circuits, and user input and output elements. Alternatively, some or all functions could be implemented by a state machine that has no stored program instructions, or in one or more application specific integrated circuits (ASICs) or field-programmable gate arrays (FPGA), in which each function or some combinations of certain of the functions are implemented as custom logic. Of course, a combination of these approaches could also be used. Thus, methods and means for these functions have been described herein.

[0070] The terms program, software, software application, and the like as used herein, are defined as a sequence of instructions designed for execution on a computer system or programmable device. A program, software, application, computer program, or software application may include a subroutine, a function, a procedure, an object method, an object implementation, an executable application, an applet, a servlet, a source code, an object code, any computer language logic, a shared library/dynamic load library and/or other sequence of instructions designed for execution on a computer system.

[0071] Herein various embodiments of the systems, apparatuses, and methods are described. In many of the different embodiments, features are similar. Therefore, to avoid redundancy, repetitive description of these similar features may not be made in some circumstances. It shall be understood, however, that description of a first-appearing feature applies to the later described similar feature and each respective description, therefore, is to be incorporated therein without such repetition.

[0072] Described now are exemplary embodiments. Referring now to the figures of the drawings in detail and first, particularly to FIGS. 1 and 2, there is shown a first exemplary embodiment of a lift 100 for water entry/exit and methods of manufacture and use thereof. The lift 100 comprises a submerged base assembly 110 and a seat assembly 120. The base assembly 110 is configured to remain submerged in a water-containing structure 10, such as a pool or a Jacuzzi (whether using fresh water or salt water, for example). The exemplary embodiment of the water-containing structure 10 in FIGS. 1 and 2 is a pool having a deck 12, coping 14, an interior wall 16, and a floor 18, and is filled with water 20. As the lift 100 remains submerged in water for most of its useful life, the parts comprising the lift 100 are waterproof or are watertight, these terms being used interchangeably. As used herein, waterproof or watertight means that the parts are solid or are sufficiently sealed to prevent any ingress of moisture that would be detrimental to the functioning of the lift 100. If the part is simply a metal bar, then that can be considered waterproof as it inherently repels water and is not damaged from immersion, periodic or constant. If the part comprises various structures, such as sensors or motors, then either the parts are inherently waterproof or they are sealed sufficiently so that they can remain in water over a given life span substantially without deterioration.

[0073] The base assembly 110 in FIGS. 1 and 2 is fixed to the interior wall 16 and, therefore depending on the level of the water 18 maintained within the pool, the base assembly 110 is either entirely or mostly submerged at all times. The base assembly 110 has a base housing 112 fixed to the interior wall 16 and, in the exemplary embodiment, extends to the floor 18 of the pool. Fixation of the base housing 112 to the wall 16 can be direct or through a non-illustrated mounting bracket. To minimize injury should a swimmer/bather contact the base housing 112, the exterior surfaces of the base housing 112 are curved. In the exemplary embodiment, the exterior surface of the base housing 112 is cylindrical. To eliminate pointy surfaces, the base housing 112 can extend all the way down to the floor 18. The upper surface of the base housing 112 is illustrated as a flat, semi-circular plane but that surface can be curved upwards as well in the shape of half of a hemisphere, referred to as a quadrasphere. The base housing 112 can, alternatively, extend only partly downwards towards the floor 18 and end at a distance from the floor 18. In this alternative embodiment, the bottom surface of the base housing 112 can be a quadrasphere. Other shapes for the base are equally possible, such as polygonal shapes, elliptical shapes, and bell curves, to name a few. The base housing 112 defines a lifting arm chamber 114, in which is disposed the seat assembly 120. As will be described in further detail below, the lifting arm chamber 114 defines an arm slot 116 that communicates and extends from the interior of the lifting arm chamber 114 to the exterior surface of the base housing 112.

[0074] Disposed within the lifting arm chamber 114 is at least a portion of the seat assembly 120. The seat assembly 120 comprises a lifting beam 130, a chair assembly 140, and a drive assembly 150. In the exemplary embodiment, the lifting beam 130 comprises a movable cylinder that lowers into and raises from the cylindrical lifting arm chamber 114. Such cooperative shapes allow the lifting beam 130 not only to raise from the lifting arm chamber 114 but also to spin within the lifting arm chamber 114. This cooperative shaping allows for beneficial bidirectional movement that will be described in further detail below. The lifting beam 130 defines a seat arm chamber 132.

[0075] The chair assembly 140 comprises a chair arm 142 and a chair 144. The chair arm 142 is pivotally connected to the lifting beam 130 within the seat arm chamber 132. In this manner, as shown with dashed lines in FIG. 2, pivoting of the chair arm 142 within the seat arm chamber 132 allows the seat to move between a stowed position or state and a deployed position or state. In the exemplary embodiment, the chair 144 is rigidly connected to the chair arm 142. Thus, in the stowed position of the chair arm 142, the chair 144 also is in a stowed position or state where the chair 144 is parallel to the wall 16 in a vertical orientation (solid lines in FIG. 2). And, when the chair arm 142 pivots out of the seat arm chamber 132, the chair 144 pivots from the vertical orientation to a horizontal orientation into a deployed position or state (dashed lines in FIG. 2). Pivoting of the chair arm 142 with respect to the lifting beam 130 can be actively powered (by the drive assembly) or can occur passively by gravity (e.g., by weighting the chair and/or shaping the chair and chair arm accordingly) or can be both active and passive in various configurations.

[0076] As the chair assembly 140 is lowered in the deployed position to the full range of the arm slot 116, and the lifting beam 130 continues to lower, the base of the arm slot 116 acts as a cam to push on the underside of the chair arm 142 and pivots the chair arm 142 into the stowed position.

[0077] The drive assembly 150 is operatively connected to the lifting beam 130 and, in an exemplary embodiment comprises a power source 152 and a drive 154 powered by the power source. Powered by the power source 152, the drive 154 moves the lifting beam 130 from a stowed position or state (shown in FIG. 2) to a deployed position or state (shown in FIG. 1). In an advantageous exemplary configuration, the power source 152 is a battery (that is solar powered or charged through a removable exterior cable connected to an electrical mains) and the drive 154 is an electric, battery-powered motor. The drive 154 can be a single drive (either directly or through a transmission) or it can be several separate drives operating in concert, e.g., through a microcontroller or by a gearing mechanism or by both. In an exemplary embodiment, the drive 142 to lift the lifting beam 130 is a worm screw, vertically mounted at a center of the lifting beam 130 and directly connected to the drive assembly 150. During the lift motion, in an exemplary embodiment, the drive assembly 150 is fixed in rotation relative to the base housing 112 and to the lifting beam 130. Once the chair arm 142 has reached the fully extended position, the lifting beam 130 permits rotation of the chair arm 142. In this regard, the chair assembly 140 can be rotated 180 degrees, either manually or mechanically.

[0078] In a particularly advantageous embodiment, the drive assembly 150 comprises a hermetically sealed, motor/battery replaceable/exchangeable part. Control of the lift 100 and, in particular, the drive assembly 150, is carried out by a controller 160, which is illustrated diagrammatically in FIG. 1. The exemplary embodiment of the controller 160 shown is a remote control with various non-illustrated user interfaces, which can be analog (e.g., buttons) and/or digital (e.g., microcomputer with software).

[0079] To operate the lift 100, reference is made to the progression of FIGS. 3 to 26. A stowed-to-deployed operation is shown in the progression from FIGS. 3 to 26 and a deployed-to-stowed operation is shown in the reverse progression FIGS. 26 to 3. In general, the user-supporting seat assembly is configured to be stored in a compact form within the water, therefore, preserving the aesthetic of the water-containing structure in which a person is to enter and exit. With an actuation of the controller 160, the lifting beam 130 with the chair 144 emerges vertically from the water. Once emerged, the lifting beam 130 rotates the seat assembly 120 on a vertical axis until the seat assembly 120 is over an adjacent portion of a deck 10, 12, thereby becoming easily accessible to the user. Before, during, or after the rotation of the lifting beam, the chair arm 142 lowers to unfold the chair 144 along with the chair's seat back 146 and/or footrest(s) 148 to receive an occupant or rider. The lifting beam 130 then rotates the seat assembly 120 about the vertical axis until the chair 144 is over the water. The lifting beam 130 then lowers to submerge the chair 144 and rider and allow discharge of the rider into the water. This process can occur with a minimal number of user interface actions or with one actuation for each step. For example, in a two-actuation process, the controller 160 is actuated in a first step to move the chair onto the deck in an occupant-ready state and is actuated in a second step, after the occupant(s) is(are) safely seated, to rotate and lower the occupant(s) into the water. It is noted that only one chair 144 is illustrated, however, the chair 144 can also be a bench or a set of chairs to accommodate more than a single occupant.

[0080] Operation is now described. The lift 100 is activated by the user, or others, by remote control or by other directly connected measures. In FIG. 3, the lift 100 rests in the stored state ready for use by an occupant, with the entire device below the water 20 and the chair 144 in the stowed state. The user activates the lift 100 and, as shown in FIG. 4, the drive assembly 150 raises the lifting beam 130, which elevates the chair 144 out of the water 20. Either the drive assembly 150 or gravity (or a combination of both) pivots the chair arm 142 to lower the chair 144 into a deployed position or state, which is shown in FIG. 5. In this exemplary embodiment, the chair assembly 140 also includes a seat back 146, which is in a stowed state resting against and/or in line with the chair 144. As shown in FIG. 6, the drive assembly 150 rotates the lifting beam 130 around its vertical longitudinal axis, which causes the chair 144 to rotate from over the water around towards a position above the deck 12 of the water-containing structure 10. FIGS. 7, 8, and 9 illustrate the lifting beam 130 in various rotational positions around the vertical longitudinal axis until the chair 144 rests in a position above the deck 12. When the lifting beam 130 is fully rotated to place the chair 144 above the deck 12, the seat back 16 is moved from the stored position into the deployed position, which is shown in the progression of FIGS. 10 and 11. In this exemplary embodiment of the chair assembly 140, with the seat back 16 deployed, a footrest 148 is automatically or manually lowered from a stowed position or state to a deployed position or state. The footrest 148 movement is illustrated in the progression from FIG. 12 to FIG. 14. The exemplary embodiment of the lift 100 is now ready for receiving an occupant.

[0081] With the occupant seated on the chair 144, the controller 160 can be actuated for delivery of the occupant into the water or various sensors can detect and/or record the seated occupant and begin the lower procedure. Even though the occupant is not shown in FIGS. 15 to 26, explanation of these figures assumes that an occupant is seated safely in the chair 144. With a lower-ready signal transmitted to the drive assembly 150, rotation of the lifting beam 130 occurs, which rotation is shown in the progression of FIGS. 15 to 17. With the chair 144 over the water 20, the drive assembly 150 lowers the lifting beam 130 with the chair assembly 140 into the water 20. Lowering of the chair 144 is depicted starting from FIG. 17 and ending at FIG. 19, in which the chair 144 is fully submerged in the water 20 and the lifting beam 130 is at its lowermost position or state. At this point, the occupant moves off of the chair 144 into the pool. The lift 100 can remain in this position with the chair 144 in a ready-to-occupy state or the chair 144 can be stowed. In the latter case, which is shown in the progression from FIG. 19 to FIG. 26, the exemplary embodiment first has the footrest 148 move from the deployed position (FIG. 19) to the stowed position (FIG. 22). Then, the seat back 146 is moved from the deployed position (FIG. 22) to the stowed position (FIG. 26). At this point, the lift 100 is ready for use again to remove the swimmer from the pool by carrying out the steps shown in reverse from FIG. 26 to FIG. 3, for example.

[0082] Advantageously, the lift 100 is a self-contained apparatus that folds to a nominal profile against the interior wall 16 of the structure 10. This provides a nominal and gradual protruding profile into the space in order to minimally affect use of the water-containing structure 10 by swimmers/users.
