Description
- This Application claims priority to U.S. Provisional Patent Application Ser. No. 61/315,452, entitled “Expandable Pool System,” filed 19 Mar. 2010, which is incorporated herein by reference in its entirety as if fully set forth below.
- 1. Field
- Embodiments of the present invention relate to an expandable container and, more particularly, to an expandable inflatable pool system.
- 2. Description of Related Art
- Portable swimming pools, or kiddy pools, are well known devices in the art. An exemplary conventional pool is formed from molded plastic, and permanently takes on the shape of a small, portable swimming pool. These molded pools exist in a variety of shapes and sizes, and consumers are able to choose the specific portable pool that suits their particular needs.
- Unfortunately, these conventional pools can be difficult to transport because they have an awkward size and shape, and are often larger than many vehicles. Commonly, to transport a molded pool, a consumer must strap it to the roof of a vehicle, or if the pool is too large for the vehicle, the purchaser must make arrangements for oversized vehicle transport. Such pools are difficult and awkward to handle or carry even for short distances.
- In addition to the challenge with transporting these molded pools, they are generally so large that they are difficult to store. In fact, among many consumers, they have become disposable due to the difficulties of storage. For example, oftentimes consumers can purchase one of these portable pools at the beginning of the summer swimming season, and then discard it during the colder months when it would otherwise need to be stored. This practice, however, is viewed by many as wasteful, and is preferably to be avoided.
- Another challenge with conventional molded plastic portable pools is that they are easily breakable. Because of this problem, the difficulty in storing such items is exacerbated as they are not easily bendable or manipulatable without the risk of breaking the item. Additionally, because of the manner in which children play in and around a portable pool, the fact that they are easily breakable is highly undesirable because it could potentially cause or contribute to injuries.
- Conventional solutions to the molded swimming pool are ring pools and frame pools, both of which are generally known in the art. A conventional ring pool is illustrated in
FIG. 1 . More specifically,FIG. 1 illustrates a side, cross-sectional view of a conventional quick-set swimming pool. The conventional quick-set swimming pool 5 includes abase 10, aside wall 20, and a risingring 30. Theswimming pool 5 is generally formed by joining thebase 10, along itsperimeter 12, to theerected side wall 20 at or near a first edge orbottom 22 of theside wall 20. - To setup the conventional quick-
set swimming pool 5, the edge of theside wall 20 that is not joined to the base 10 (i.e., the top) can have the risingring 30 coupled thereto. The risingring 30 can comprise a variety of different elements capable of aiding the transformation of the swimming pool from a collapsed configuration to an expanded configuration by erecting theside wall 20. For example, the risingring 30 can be a floating device that floats on the water in theswimming pool 5, causing theside wall 20 to rise as more water is inserted in theswimming pool 5. - A problem with conventional molded pools, ring pools, and frame pools is that they all have a fixed depth, which cannot be increased over time, which may be desirable.
- Briefly described, embodiments of the present invention relate to an expandable swimming pool. The expandable swimming pool includes a base, a side wall in communication with a perimeter of the base, and an expansion system incorporated into the side wall. The expansion system permits the side wall to extend or shorten the height of the side wall. As the expansion system increases, the volume of the pool likewise increases. Oppositely, as the expansion system decreases, the volume of the pool decreases.
- In some embodiments, the expansion system includes a track and a slide fastener. The expansion system can extend one or more times around the perimeter of the pool, e.g., if shaped in a circle, the expansion system extends around the entire circumference of the pool at least one time.
- In operation, the slide fastener can be pulled around the perimeter of the pool along the track. Depending on the direction that the slide fastener is pulled, the expansion system can increase or decrease the depth of the pool.
- Embodiments of the present invention relate to an expandable inflatable pool system. In an exemplary embodiment, the expandable inflatable pool system appears as a conventional two-ring child's pool. Between each of the two rings is an expansion system. In an exemplary embodiment, the expansion system includes a zipper adaptable to unzip and expose a third ring. The ring can then be inflated resulting in a pool of greater depth. On the other hand, a three ring pool can be reduced to a two ring pool. In addition, the expansion system permits more than one zipper to enable additional chambers to further increase/decrease the depth of the pool. A benefit of the expandable inflatable pool system is that when child is young a first depth may be desired and/or appropriate, but as the child grows, the size and depth of the pool can be increased, thus reducing the need to purchase new pools every season as the child continues to grow.
- Further features of embodiments of the present invention, and the advantages offered thereby, are explained in greater detail hereinafter with reference to specific embodiments illustrated in the accompanying drawings, wherein like elements are indicated by like reference designators.

In particular, embodiments of the present invention are described in the context of being an expandable pool system. Because of its collapsible nature, aspects of the invention can be easily stored, be readily portable, and can increase/decrease the height of the side wall.
- Embodiments of the present invention, however, are not limited to its use as an expandable pool system. Rather, embodiments of the invention can be used wherever a collapsible and/or pop-up container that provides for convenient storage is needed or desired. Thus, the container described hereinafter as a portable swimming pool can also find utility as a container for a variety of fluids, liquids, or other substances that require or could make use of such a collapsible container.
- Additionally, the materials and components described hereinafter as making up the various elements of the container are intended to be illustrative and not restrictive. Many suitable materials and components that would perform the same or a similar function as the materials and components described herein are intended to be embraced within the scope of the invention. Such other materials and components not described herein can include, but are not limited to, materials and/or components that are developed after the time of the development of embodiments of the present invention, for example.
- Embodiments of the present invention provide several exemplary embodiments of collapsible containers that can be used as a swimming pool. These collapsible containers are generally formed by joining a base, along its perimeter, to an erected side wall at or near one edge (i.e., a bottom) of the side wall, wherein the side wall incorporates an expandable system.
- An upward force providing member or shape retaining member, or combination thereof, can be positioned along the edge of the side wall (i.e., near a top). The upward force providing member or shape retaining member generally has at least a portion coupled proximate to the end of the side wall not joined to the base. The upward force providing member can comprise a variety of different elements capable of aiding the transformation of the collapsible container from a collapsed configuration to an expanded configuration by erecting the side wall. For example, the upward force providing member can be a floatation device that floats on fluid in the container, causing the side wall to rise as additional fluid is deposited in the container. The floatation device can effectively cause the side wall to be approximately normal the base or the surface upon which the base sits. Additionally, the floatation device is positioned within the interior of the container, as it extends inwardly toward a center of the base.
- A support member and/or shape retaining member can be formed from one or more support members having at least a portion coupled proximate to the side wall of the pool. For example, vertical rib supports may be used as an upward force providing member, a shape-retaining member, or both. Such vertical ribs can be formed from individual inflatable portions, or can be a foam insert, or the like. According to some embodiments, such vertical ribs can be collapsible, being formed from collapsible inflatable portions, collapsible foam portions, or other suitable compositions.
- In some embodiments, the pool can also incorporate at least one porthole in the side wall. A plurality of portholes can be provided, each being a translucent portion of the side wall, and being transparent. The portholes provide a window-like mechanism permitting one to see into the pool through the side wall. Similarly, the portholes enable one within the pool to see outside the pool.
- In some embodiments, the pool can also include a pump device for cleaning and filtration purposes. In some embodiments, if the pump device is present a fountain device can be positioned in the pool to provide decorative movement of the fluid, commonly water.
- The expansion system can be incorporated into the side wall of the pool. The expansion system, like the side wall, can be constructed of flexible material and has main section and secondary section which can be retained within the main section when the side wall is in its non-expanded condition. Each of the main and secondary sections can have two side panels and two end panels joining the side panels, and each of the main and secondary sections include a zipper closure member having mating halves secured to the upper periphery of the side and end panels. A zipper slide effects engagement of the mating halves of the zipper beginning at one end panel and ending at the opposite end panel, the start and finishing ends of the zipper projecting for a short distance beyond the respective side panels. In some embodiments, a tab can be connected to the starting end of the zipper to join the mating halves thereof, and another tab is connected to the zipper slide, each of the tabs being equipped with a fastening means such as a snap fastening means to permit drawing down the projecting zipper ends against the respective ends panel and securing the zipper ends in this position.
- A container, or portable swimming pool, constructed in accordance with an exemplary embodiment of the invention is illustrated in
FIG. 2 . As shown inFIG. 2 , aswimming pool 100 has abase 110 and aside wall 120, which is made from a flexible material and is formed in a particular shape. As will be discussed in more detail below, thepool 100, more specifically theside wall 120 incorporates anexpandable system 200 to enable the side wall to increase and/or decrease in height and thus increasing and/or decreasing the depth of thepool 100. - The
pool 100 can be a frame pool or a pop-up type of pool, both of which are collapsible in nature. The frame pool can be pre-fabricated and adapted to include a plurality of external vertical braces or frames for supporting the frame pool above the ground. The vertical braces or frames, which can be optionally provided, can be made of plastic, metal, and the like. In some embodiments, the pop-up pool is adapted to rise with the amount of water inserted into pool, and can also be outfitted with external braces or frames for additional support. In an exemplary embodiment, thepool 100 can be a combination of the frame and pop-up pools having elements of both devices. Other types of pools can be used with embodiments of the present invention. - The shape of the
pool 100 can be circular, oval, and the like. Thepool 100 can be made in a variety of shapes, including, but not limited to, rectangular, square, oblong, oval-shaped, elliptical, rectangular with rounded corners, and the like. Different shapes can result in thepool 100 having more than oneside wall 120 forming the perimeter of thepool 100. Additionally, thepool 100 can be made in a variety of sizes, depending upon the desired use. - The
pool 100 is formed with thebase 110 andside wall 120. Thebase 110 andside wall 120 can be manufactured out of many different materials and can be formed of the same materials or each a different material. For example, thebase 110 andside wall 120 of theswimming pool 100 can be formed from a textile (e.g., burlap, etc.) or synthetic material (e.g., plastics, polyurethane, PVC, nylon, etc). Many materials (especially water-permeable textiles, etc.) can be used to construct a pool; the materials, however, are preferably treated to retain water. For example, such materials could be adhered to, laminated with, coated with, or bonded to a material impermeable to water. In accordance with the embodiment shown inFIG. 2 , the base 110 can be formed from a nylon shell, which can be laminated or otherwise treated to hold water. For example, the nylon shell might be bonded to another material, such as a polyurethane, PVC, vinyl, or other suitable impermeable lining to provide the desirable waterproof qualities, and to provide a more pleasing tactile quality to the interior of thepool 100. Similarly, thewall 120 of thepool 100 can be constructed from these materials, or other materials having similar suitable qualities. Many of the materials that are used can be selected for their durability. - For example, the base 110 can be formed from materials that are more durable than the
side wall 120, as this section of thepool 100 will likely be subjected to more wear than theside wall 120. Also, as described, thebase 110 andside wall 120 can be formed from a combination of materials, which can be adhered or bonded together. The materials used for the various portions of thepool 100, including, for example, thebase 110 and theside wall 120, can be joined by way of a number of commonly known suitable techniques, such as sewing, adhesives, bonding, lamination, RF welding, other suitable joining techniques, and the like. The connection of the base 110 to theside wall 120 can be along thebottom 122 of theside wall 120. Thebase 110 includes a perimeter, wherein thebottom 122 of theside wall 120 can be connected thereto. - The
side wall 120 can comprise both aninner wall 126 and anouter wall 128. In some embodiments, theinner wall 126 can be sealable to theouter wall 128. In some embodiments, theside wall 120 can be inflatable and spring activated. In some embodiments, theside wall 120 can be non-inflatable and non-spring activated. In some embodiments, theinner wall 126 can be an approximately vertical wall, while theouter wall 128 can be formed of an inflatable conduit. - In some embodiments, the
inner wall 126 can be made of pliable plastic, while theouter wall 128 can be made of hard plastic. Then, theinner wall 126 can limit leakage of fluid should theouter wall 128 crack or pierced Likewise, the material of theinner wall 126 can be made of hard plastic, and the material of theouter wall 128 can be made of pliable material to protect from potential leakage should the hard plastic crack. In another embodiment, theinner wall 126 can be made of hard plastic, while theouter wall 128 can also be made of hard plastic. - In some embodiments, the
pool 100 may include afloatation device 130, which is formed in the shape of thepool 100, and can be attached near the top 124 of theside wall 120. According to an exemplary embodiment, thefloatation device 130 can be an inflatable ring. Thisfloatation device 130, if inflated, can provide some stiffness at the top 124 of theside wall 120, and can help maintain the overall shape of thepool 100. Moreover, thefloatation device 130 can provide padding for those entering and exiting thepool 100, and can also provide a manner by which thepool 100 changes from a collapsed to an expanded configuration with the addition of water within thepool 100. Additionally, thefloatation device 130 can be buoyant, meaning it can be made to rise with the level of water within thepool 100, such that as water is deposited in thepool 100 and thefloatation device 130 rises with the level of that water, theside wall 120 is automatically erected as thepool 100 is filled. - The
floatation device 130 can be made from a variety of materials. For example, thefloatation device 130 can be a standard inflatable polyurethane casing, or similar casing that is suitable for retaining air or other gas in an inflated state. Additionally, thefloatation device 130 can make use of a variety of chemical or other reactions that would automatically inflate it. Thefloatation device 130 can be inflated by conventional means, for example by a valve configured for oral inflation or for inflation by a device such as a pump, and the like. - The
floatation device 130 can also be made from material that does not require inflation, but provides adequate buoyancy and floats on the water contained within the pool 100 (or other fluid when the pool is used as a general container). For example, special foams, polystyrene, or other materials can be used to create afloatation device 130, which would float with the water line contained in thepool 100, and cause thewalls 120 to be erected as thepool 100 fills. In this manner, thepool 100 can automatically change from a collapsed to an expanded configuration. As thepool 100 is a collapsible pool, and adapted to be folded, thefloatation device 130 can be made of a material that can be subjected to folding, without becoming damaged. Although some potential materials from which thefloatation device 130 can be formed have been mentioned above, other materials including, but not limited to, newly developed materials can be incorporated within the design of the invention, and used to form thefloatation device 130 without departing from the invention. - The
floatation device 130 can be of a nature other than an inflatable ring. For example, thisfloatation device 130 can be made of a material that floats, and is bendable, such that it can be folded or bent. - In some embodiments, the
side wall 120 can be inflatable. Providing media, such as air, to the inflatable side wall can be accomplished viavalve 129. In an exemplary embodiment, the side wall can comprise a plurality of inflatable rings. Each ring can have itsown valve 129. - The
pool 100 can be conveniently collapsed for storage and/or transport by deflating theinflated floatation device 130 and folding onto itself along with thebase 110 andside wall 120 material in a manner that is well known. - The
pool 100 includes anexpansion system 200. Theexpansion system 200 can be incorporated in theside wall 120 of thepool 100. Theexpansion system 200 permits the depth of thepool 100 to increase or decrease, as desired, as theside wall 120 of thepool 100 can be increased or decreased, respectively. - In an exemplary embodiment, the
expansion system 200 includes amain compartment 210 with one ormore expansion joints 212 to increase the height of theside wall 120, and thus increase the size of thecompartment 210. In conjunction with themain compartment 210, there is also provided a separable end compartment having an inner flexible membrane that can be extended beyond the expansion joints to maximize the volume of the pool, when the expansion joints are open. - In an exemplary embodiment, each
expansion joint 212 of theexpansion system 200 includes aslide fastener 215 andzipper track 218. One end of thezipper track 218 underlies the opposite end of thezipper track 218 in an overlapping relationship, such that when theexpansion joint 212 is closed, the slide fasteners looking like normal zippers. When theexpansion joint 212 is opened by thezipper 215 being opened, the joint 212 can be opened at least 360 degrees around its circumference, or perimeter. By having twoexpansion joints 212, the joint 212 can be used together to get the maximum volume expansion in thepool 100 or can be used separately to provide an intermediate amount of expansion, wherein one side of thepool 100 can have higher side wall than an opposite side, which may be preferable when thepool 100 is positioned on an incline, for example. - The
expansion system 200 can be covered by a portion of theouter side wall 128 to be hidden from view. - In some embodiments, the
pool 100 can further comprise aporthole 150, or a plurality thereof. Generally, theportholes 150 are translucent sections of theside wall 120, either integrally formed in/with theside wall 120, or separate elements. Theportholes 150 can perform like a window permitting one to see into thepool 100. Similarly, theportholes 150 enable one within the pool to see outside thepool 100. Theportholes 150 can further enable determining the level of fluid within thepool 100. - The
portholes 150 can have particular shapes. In some embodiments, the shape of theportholes 150 can be oval. Other embodiments provide that theportholes 150 can be round or circular. The configuration of theporthole 150 can be many shapes. In an exemplary embodiment, the locations of theportholes 150 can be placed symmetrically about theside wall 120. - In some embodiments, the
portholes 150 can aid in safety, as theportholes 150 can enable viewing into thepool 100 through theside wall 120. If theportholes 150 are removably designed by suitable means, aporthole 150 can also be used as a drainage device, enabling quick emptying of the fluid of thepool 100. Theportholes 150 can be integrally formed during manufacturing of theside wall 120, or removable, wherein they are attached via a waterproof/leak resistant means. Theportholes 150 can also be included via a non-removable method, wherein theportholes 150 are secured within theside wall 120. - The
portholes 150 can be secured in different ways within theside wall 120. In one embodiment, theportholes 150 can be flush with theside wall 120, such as enabling a drainage device. In another embodiment, theportholes 150 can be insertable between theinner wall 126 and theouter wall 128 of theside wall 120. In some embodiments, theportholes 150 can be sealable between theinner wall 126 and theouter wall 128, wherein there is a hole between theinner wall 126 and theouter wall 128, whereby theporthole 150 seals the hole. Theporthole 150, thus, can be sandwiched between theinner wall 126 and theouter wall 128. Theporthole 150 can be sealed by conventional compression or heat sealed methods. - The
pool 100 can further include apump device 140. Thepump device 140 can be adapted as a circulation system, and beneficially as a cleaning system. Thepump device 140 can be integral with thepool 100, or positioned nearby. Thepump device 140 can comprise afirst tube 142 coupling a suction port of thepump device 140 in fluid communication with a main drain or mobile cleaning device (neither shown) which draws water and settled debris from the bottom of thepool 100. Thepump device 140 can further comprise asecond tube 144 to a coupling device which diverts a small portion of pool “return” water pumped from an outlet port of thepump device 140. Furthermore, thepump device 140 can be adapted to provide a jet of air bubbles in the water, for a Jacuzzi or spa effect. - Fountains are aesthetically pleasing, and are often desired to be positioned within the
pool 100. In some embodiments, afountain device 155 or fluid discharge device, can be positioned within thepool 100 for controlling fluid supplied by thepump device 140 in a decorative fashion. Thepump device 140 can control the elevation of fluid as it is ejected from thefountain device 155, as well as the rise and fall of the fluid. Thefountain device 155 is preferably positioned in thepool 100, and can be in communication with thepump device 140 or other filtering device to control the rise and fall of fluid. - In some embodiments, particularly those in which the pool has a side wall exceeding approximately three feet in height, the
pool 100 can also have one or more braces orstructural supports 160. Thesupport 160 can include vertical rib supports, and can be coupled proximate to theside wall 120 of thepool 100. Thesupport 160 can be inserted within the material making up theside wall 120. Thesupport 160 can comprise at least a portion of thefloatation device 130 or a support member, and can have at least a portion coupled to the top of theside wall 120 and vertically along theside wall 120 to provide buoyancy and/or rigidity to theside wall 120. Thesupports 160 can comprise, for example, one or more inflatable bladders, collapsible foam, removable support members, and the like. - The
supports 160 can be used on a frame pool, as well as a pop-up pool for supporting the pool above the ground. In an exemplary embodiment, thesupport 160 is positioned outside thepool 100. Thesupport members 160 can be made of plastics, metals, and the like. - The
pool 100 can include aladder 170 enabling one to enter and/or exit thepool 100. Theladder 170 can be integral with thebrace 160, or not. Theladder 170 is preferable in embodiments in which the height of theside wall 120 of thepool 100 exceeds approximately three feet. Theladder 170 can be insertable into thepool 100, enabling one to exit thepool 100 from the inside. Because a rim of thepool 100 is above the ground, theladder 170 is preferably flush with the rim for easy entry/exit from thepool 100. - Because the
pool 100 is collapsible, the fluid in thepool 100 can be drained therefrom. Exemplarily, adrainage assembly 180 is integral with thepool 100. In an exemplary embodiment, thedrainage assembly 180 is a cork or like device, that is removeable from thepool 100, such that, when removed the water from thepool 100 can be drained. Thedrainage assembly 180 can also be a valve enabling control of draining thepool 100. Thedrainage assembly 180 can be many devices enabling easy draining of thepool 100, safely and environmentally. - In some embodiments, the
pool 100 can also include alight source 190 for illumination purposes. The light source provides light when energized. The light source can be many types of light sources, including a light bulb, light emitting diode (LED), incandescent lamp, halogen lamp, fluorescent lamp, and the like. In an exemplary embodiment, thelight source 190 is an LED, as they can last longer than a halogen lamp or conventional light bulb, and LEDs can be controlled to emit various color patterns. In an exemplary embodiment, thelight source 190 can be secured to or embedded in either theside wall 120 or thefloatation device 130. The light source can be powered by either an electrical outlet near thepool 100, or by a temporary power source, such as a battery, positioned within thepool 100. - From the foregoing, it can be seen that the invention provides a number of different collapsible containers with generally vertical side walls and a floatation device positioned atop the generally vertical side wall, which can be used as swimming pool. The various embodiments of the invention described above provide collapsible swimming pool that are foldable, enable easy storage, and increase portability when compared with prior approaches. Additionally, according to various embodiments of the invention, the collapsible swimming pool of the invention can be provided with a pop-up mechanism that automatically erects the pool to its full-sized, expanded configuration.
- Embodiments of the present invention can be embodied in other specific forms without departing from the spirit or essential characteristics thereof. For example, while embodiments of the invention have been described in the context of swimming pool the concepts described herein need not be limited to these illustrative embodiments. For example, swimming pools of larger sizes can be constructed using the same methods, and would enjoy the same benefits as the kiddy pool described above. Additionally, other types of containers, which can be used to contain fluids or other substances could be constructed using the principles of the invention and enjoy similar advantages as those described above.
- As described, embodiments of the present invention relate to an expandable inflatable pool system. In an exemplary embodiment, the expandable inflatable pool system appears as a conventional two-ring child's pool. Between each of the two rings is a expansion system. In an exemplary embodiment, the expansion system includes a zipper adaptable to unzip and expose a third ring. The ring can then be inflated resulting in a pool of greater depth. On the other hand, a three ring pool can be reduced to a two ring pool. In addition, the expansion system permits more than one zipper to enable additional chambers to further increase/decrease the depth of the pool. A benefit of the expandable inflatable pool system is that when child is young a first depth may be desired and/or appropriate, but as the child grows, the size and depth of the pool can be increased, thus reducing the need to purchase new pools every season as the child continues to grow.
- Embodiments of the present invention incorporate a use of a fastening device, e.g., a zipper, to allow the pool to be expandable.
- Embodiments of the present invention permit the use of multiple fasteners to create a pool of varying sizes.
- The expandable system can be used on a non-inflatable pool, e.g. quickset-type using a non-inflatable sidewall, or an inflatable pool.
- Additionally, the specific configurations, choice of materials, and the size and shape of various elements can be varied according to particular design specifications or constraints requiring a container constructed according to the principles of the invention. Such changes are intended to be embraced within the scope of the invention.
- The presently disclosed embodiments are, therefore, considered in all respects to be illustrative and not restrictive. The scope of the invention is indicated by the appended claims, rather than the foregoing description, and all changes that come within the meaning and range of equivalents thereof are intended to be embraced therein.
