Definitions
- the present invention relates to portable pools, and in particular, to a portable spa pool that can be conveniently moved from one location to another, and which can be conveniently and quickly installed and disassembled.
- spa pools have become increasingly popular as people have come to recognize and enjoy the relaxing and healthy benefits accorded by a good invigorating soak in a spa pool or tub.
- Most conventional spa pools are provided in the form of a spa tub in a bathroom or a health club, or in the form of an outdoor spa.
- Each of these spa pools has a jet nozzle system that must be powered by a pump and its associated plumbing.
- Some spa pools are also provided with a heater that works in conjunction with the pump to heat the water that is recirculated in the spa pool.
- the entire spa pool and its accompanying jet nozzle system, pump, plumbing and heater must be completely dis-assembled and moved.
- Such dis-assembly can be quite complex, and often requires the expertise of a plumber. Even if a normal user is able to accomplish the dis-assembly on his or her own, such dis-assembly is very time-consuming and difficult, and any subsequent re-assembly will be equally time-consuming and challenging.
- conventional spa pools tend to stay fixed in their original locations, and are unlikely to be moved to a different location.
- Such lack of portability is a significant drawback, since nowadays people are more mobile and often enjoy travelling and moving about. It would be desirable if they could also enjoy the luxury and benefit of the spa pool at different locales while not experiencing the inconveniences and difficulties associated with having to assemble and dis-assemble a conventional spa pool. This would encourage and promote increased use of spa pools.
- the objectives of the present invention are accomplished by providing a spa pool having an enclosing wall that has at least one inflatable chamber, and a plumbing system retained in the interior of the wall.
- the plumbing system includes a plurality of jet nozzles, and a plurality of hoses that couple the plurality of jet nozzles.
- the wall can have two openings that communicate the interior with the exterior of the spa pool, the two openings including a first opening coupled to an inlet for receiving water into the interior from a pump, and a second opening coupled to an outlet for delivering water from the interior to a pump.
- a liner can be provided to overlie the enclosing wall, and a cover can be provided to overlie the liner and enclosing wall.
- a pump can be coupled to the interior of the pool, and a heater coupled to the pump for heating water that passes through the pump.
- a case can also be provided for holding the enclosing wall, the jet nozzles, the hoses, the pump and the heater.

- FIG. 14 is a cross-sectional view of a gasket that may be used with the spa pool assembly of FIG. 3.
- FIG. 15 is a partial cross-sectional view of the spa pool of FIG. 1 illustrating a modification thereto.
- the present invention provides a spa pool that can be easily and quickly assembled and dis-assembled without the need for any special tools.
- the spa pool of the present invention provides a plumbing system that requires the use of only two openings in the pool, thereby minimizing the potential for water leakage. The potential for water leakage is further minimized by providing the plumbing system inside the spa pool.
- the present invention provides a compact storage case that can be used to house the pump, heater, and the components of the dis-assembled spa pool so that the spa pool can be conveniently moved from one location to another. Other benefits and features will be described in connection with the spa pool hereinbelow.

- the unit 28 has a casing 178 , with a water outlet 180 that is adapted to be connected to the water inlet 30 , and a water inlet 182 that is adapted to be connected to the water outlet 32 .
- the casing 178 houses a motor 184 , a pump 186 mounted on and controlled by the motor 184 , and a heater 188 .
- the heater 188 can be automatically activated by a water pressure sensor (built into the heater) which turns on the heater 188 when water begins to travel through it.
- the heater 188 can also be provided with an automatic maximum temperature cut-off if the water reaches a pre-selected maximum temperature (e.g., 104 degrees Fahrenheit).
- An air button 190 extends from outside the casing 178 and is coupled to the motor 184 via a vacuum tube 185 .
- the air button 190 functions to turn on the heater 188 and the pump 186 (by operating the motor 184 ), and is used to provide additional safety to the user because the user is not exposed to any electrical components when turning on and off the pump 186 .
- One or more grills 192 are provided on the casing 178 to function as a vent for allowing cool air to enter the casing 178 to cool the motor 184 , pump 186 and heater 188 .
- a cooling fan (not shown) can be mounted in the rear of the casing 178 to cool the motor 184 , pump 186 and heater 188 .
- a power cord 194 extends from the motor 184 through the casing 178 .
- Handles 198 can be provided on the casing 178 to allow the user to lift and carry the unit 28 .
- the unit 28 can be embodied in the form of the PS-1 System marketed by Spa Builders System Group.
- water from the water outlet 32 of the pool 22 enters from the inlet 182 and is pumped by the pump 186 through the heater 188 and then out through the outlet 180 to be delivered via the water inlet 30 of the pool 22 to the interior 34 of the pool 22 .
- a carrying case 200 can be provided to store the pump and heater unit 28 and the dis-assembled components of the portable spa pool assembly 20 .
- the case 200 has a hinged cover 202 to cover a container body 204 .
- a handle 206 can extend from one end 208 of the container body 204 , and a set of wheels 210 can be provided adjacent another end 212 thereof so that a user can pull the fully-loaded case 200 like pulling a piece of luggage.
- the container body 204 defines an interior space 214 that is large enough to fit the pump and heater unit 28 , and the dis-assembled components of the portable spa pool assembly 20 .
- the interior space 214 can even be divided into separate compartments 220 and 222 (with the divider 224 shown in phantom in FIG. 13) so that the unit 28 can be securely stored in one compartment 222 , and the other components in the other compartment 220 .
- the assembly and operation of the portable spa pool assembly 20 will now be described.
- the user can unload all the disassembled components of the portable spa pool assembly 20 from the case 200 if the case 200 is provided.
- the pump and heater unit 28 can be removed from the case 200 , or retained inside the case 200 .
- the spa pool 22 is then inflated by inflating the two air chambers 72 and 76 .
- the water inlet 30 is then coupled to the water outlet 180 of the pump and heater unit 28
- the water outlet 32 is then coupled to the water inlet 182 of the pump and heater unit 28 .
- the strainer 90 can be fitted over the opening 88 .
- the plumbing system is then assembled to the configuration shown in FIG. 5 or FIG.
- each jet nozzle housing 116 is secured to the inner wall 84 of the central groove section 74 at the locations of the connectors 166 according to the techniques illustrated in connection with FIGS. 9 and 10.
- the T-connector 150 is then connected to the water inlet 30 , and the T-connector 152 is connected to the air control 156 .
- the plumbing system would be secured inside the central groove section 74 .
- the liner 24 and cover 26 can then be placed over the pool 22 , in the manner shown in FIG. 2.
- the user plugs in the power cord 194 to a power source, and then turns on the motor 184 by actuating the air button 190 . Since the pump 186 has been primed, water can be drawn through the strainer 90 and opening 88 through the tubing 86 and into the pump 186 . The water is then pumped through the heater 188 and via the water outlet 180 and water inlet 30 to the water hoses 114 and delivered to each jet nozzle housing 116 , where the water can be ejected from each corresponding jet nozzle 110 . The heater 188 is automatically turned on when water begins to circulate through the system. The water is re-circulated in the same manner.
- Air bubbles can be ejected through each jet nozzle 110 due to an air pressure system.
- the air control 156 is like an air inlet, and it couples the air hoses 112 to the ambient.
- the user can control the amount of air that enters the air control, so as to create an air pressure that is lower than the water pressure. Air is drawn from vacuum created by the high water pressure, so the lower air pressure and higher water pressure will cause air bubbles to be generated where the air meets the water in the central tubing 128 (as shown in FIG. 7), and then delivered via the jet nozzles 110 to the interior 34 of the spa pool 22 .
- the user turns off the motor 184 , and disconnects all the components by reversing the steps described above.
- the air chambers 72 and 76 are then deflated and all the components can be stored inside the carrying case 200 .
- the plumbing system can be installed into or taken out of the spa pool 22 without deflating the spa pool 22 .
- the present invention also provides a unique gasket 82 that is illustrated in FIG. 14.
- the gasket 82 further minimizes the possibility of leakage of water from the interior 34 .
- the gasket 82 is provided to seal and secure portions of tubing, and even though the tubing 86 is illustrated in FIG. 14, the same principles illustrated in FIG. 14 can be utilized for any of the other gaskets 82 shown in FIG. 3.
- the tubing 86 is preferably a hard tubing (e.g., made from hard PVC) that is injection-molded and provided with grooves or ribs 228 to provide an uneven (i.e., non-smooth) surface.
- the grooves or ribs 228 are positioned adjacent the inner wall 84 where leakage is most likely to occur.
- the gasket 82 is made from a soft material, such as soft PVC, which is then injection-molded and bonded directly over the tubing 86 on to the surface of the tubing 86 . Since both the tubing 86 and the gasket 82 are made from the same material (PVC), this process creates a homogeneous bond that is essentially one material. To provide further protection against leakage, the gasket 82 can be formed with two annular side flanges 230 and 232 that extend over a greater length of the tubing 86 away from the location of the inner wall 84 . The gasket 82 functions not only to prevent water leakage, but also to secure the tubing 86 at a designated location. Although PVC is used as an example for the material for the gasket 82 and the tubing 86 , other materials can also be used, such as but not limited to metal, rubber or plastics.
- FIG. 15 illustrates a modification to the air chambers 72 and 76 that would provide further support to these chambers 72 and 76 .
- Each air chamber 72 and 76 can be provided with an inflatable inner tube 73 and 77 , respectively, to provide support and to further minimize leakage should either air chamber 72 , 76 be damaged or spring a leak.
- Respective valves 79 and 81 extend through the air chambers 72 and 76 into the interior 34 of the pool 22 , through which air can be introduced to inflate the inner tubes 73 and 77 , respectively. Although the valves 79 and 81 are illustrated as extending into the interior 34 of the pool 22 , it is also possible to have the valves 79 , 81 extend towards the exterior of the pool 22 .
- the spa pool assembly 20 of the present invention provides a number of benefits.

Description
- 1. Field of the Invention
- The present invention relates to portable pools, and in particular, to a portable spa pool that can be conveniently moved from one location to another, and which can be conveniently and quickly installed and disassembled.
- 2. Description of the Prior Art
- Spa pools have become increasingly popular as people have come to recognize and enjoy the relaxing and healthy benefits accorded by a good invigorating soak in a spa pool or tub. Most conventional spa pools are provided in the form of a spa tub in a bathroom or a health club, or in the form of an outdoor spa. Each of these spa pools has a jet nozzle system that must be powered by a pump and its associated plumbing. Some spa pools are also provided with a heater that works in conjunction with the pump to heat the water that is recirculated in the spa pool. Unfortunately, in order to move a conventional spa pool to a different location, the entire spa pool and its accompanying jet nozzle system, pump, plumbing and heater must be completely dis-assembled and moved. Such dis-assembly can be quite complex, and often requires the expertise of a plumber. Even if a normal user is able to accomplish the dis-assembly on his or her own, such dis-assembly is very time-consuming and difficult, and any subsequent re-assembly will be equally time-consuming and challenging. In other words, conventional spa pools tend to stay fixed in their original locations, and are unlikely to be moved to a different location. Such lack of portability is a significant drawback, since nowadays people are more mobile and often enjoy travelling and moving about. It would be desirable if they could also enjoy the luxury and benefit of the spa pool at different locales while not experiencing the inconveniences and difficulties associated with having to assemble and dis-assemble a conventional spa pool. This would encourage and promote increased use of spa pools.
- Another drawback associated with conventional spa pools is that the plumbing systems are typically provided outside the pool. Unfortunately, conventional plumbing systems are quite susceptible to leaks (e.g., at the hose connections with the jet nozzles), which makes it less desirable to use such conventional spa pools inside the house.
- Thus, there remains a need for a portable spa pool that overcomes the problems associated with the conventional spa pools, which minimizes leaks, which can be installed and disassembled for storage in a quick and convenient manner, and which can be packed and moved about conveniently.
- It is an objective of the present invention to provide a portable spa pool which can be installed and dis-assembled for storage in a quick and convenient manner, and which can be packed and moved about conveniently.
- It is another objective of the present invention to provide a portable spa pool which minimizes leakage of water that is contained inside the spa pool.
- The objectives of the present invention are accomplished by providing a spa pool having an enclosing wall that has at least one inflatable chamber, and a plumbing system retained in the interior of the wall. The plumbing system includes a plurality of jet nozzles, and a plurality of hoses that couple the plurality of jet nozzles. The wall can have two openings that communicate the interior with the exterior of the spa pool, the two openings including a first opening coupled to an inlet for receiving water into the interior from a pump, and a second opening coupled to an outlet for delivering water from the interior to a pump.
- In one embodiment of the present invention, a liner can be provided to overlie the enclosing wall, and a cover can be provided to overlie the liner and enclosing wall. In another embodiment of the present invention, a pump can be coupled to the interior of the pool, and a heater coupled to the pump for heating water that passes through the pump. A case can also be provided for holding the enclosing wall, the jet nozzles, the hoses, the pump and the heater.

- The following detailed description is of the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims. In certain instances, detailed descriptions of well-known devices and mechanisms are omitted so as to not obscure the description of the present invention with unnecessary detail.
- The present invention provides a spa pool that can be easily and quickly assembled and dis-assembled without the need for any special tools. The spa pool of the present invention provides a plumbing system that requires the use of only two openings in the pool, thereby minimizing the potential for water leakage. The potential for water leakage is further minimized by providing the plumbing system inside the spa pool. In addition, the present invention provides a compact storage case that can be used to house the pump, heater, and the components of the dis-assembled spa pool so that the spa pool can be conveniently moved from one location to another. Other benefits and features will be described in connection with the spa pool hereinbelow.
- Referring to FIGS. 1 and 2, the present invention provides a portable
spa pool assembly 20 that has apool 22, aliner 24 that covers the internal walls of thepool 22, and a cover 26 (e.g., such as a nylon cover) that can be used to overlay theliner 24 and thepool 22. Thepool 22 is shown in greater detail in FIGS. 2-4, and is coupled to a pump andheater unit 28 via awater inlet 30 and awater outlet 32. The water inlet 30 and thewater outlet 32 are the only two openings provided in the walls of thepool 22 that communicate with the water-containinginterior 34 of thepool 22. Theliner 24 has a generallycircular container portion 42 that is adapted to receive water, and an annular fold-over flange orcollar 44 provided along the topannular edge 46 of thecontainer portion 42. Theliner 24 has twoopenings 36 and 38 that are provided in thewall 48 of thecontainer portion 42 and aligned with thewater inlet 30 and thewater outlet 32, respectively. In addition, a plurality ofopenings 40 are spaced apart about thewall 48, with eachopening 40 aligned with one nozzle of the jet nozzle system described below. Theliner 24 is preferably made from a material that is water-impervious and which is capable of tolerating heat and cold. Non-limiting examples of the material can include PVC, rubber, nylon, PU lamination, and polyethylene. Theliner 24 also acts as a water-containing layer of material that protects against water leakage, and to protect thepool 22 itself from puncture or other damage. Cold-crack additives (i.e., cold weather proofing) and other additives can be coated or added to theliner 24 to improve the durability of theliner 24. Thecover 26 is sized and configured similarly as theliner 24, and has aninner layer 52 that overlies thecontainer portion 42 of theliner 24, anannular lip portion 54 that overlies thecollar 44, and an annularouter layer 56 that overlies the outer periphery of thecollar 44 and thepool 22. Thecover 26 has twoopenings 58 and 60 that are provided through theinner layer 52 and theouter layer 56, and are aligned with thewater inlet 30 and thewater outlet 32, respectively. In addition, a plurality ofopenings 62 are spaced apart about theinner layer 52, with each opening 62 aligned with anopening 40 of theliner 24, and one nozzle of the jet nozzle system described below. Thecover 26 can perform two functions. First, the surfaces of thelayers spa pool assembly 20. Second, thecover 26 can provide an additional layer of protection for thepool 22 itself to prevent puncture or other damage to thepool 22 and theliner 24, and to protect against water leakage. Thecover 26 can be made from a material that is waterproof, mold-resistant, washable and which provides a good texture or feel (since the user would be sitting on the cover 26). Nonlimiting examples of these materials include a nylon with a polyurethane coating that waterproofs the nylon, or a fabric. - In addition, an
outer cover 27 can be provided to completely insulate and cover the interior 34 of thepool 22. For example, theouter cover 27 can prevent heat loss due to air convection when thepool 22 is being heated up for use. Theouter cover 27 also serves as a winter or outdoor protective cover, and can be helpful in preventing children from inadvertently falling into thepool 22. - Referring now to FIGS.2-4, the
pool 22 has anannular side wall 70 that defines the interior of thepool 22 and supports theliner 24. Theannular side wall 70 has three separate sections, a first or lowerinflatable air chamber 72, a non-inflatablecentral groove section 74, and a second or upperinflatable air chamber 76. Theair chambers spa pool 22 when fully inflated, and can be made from any of the materials described above for theliner 24 and thecover 26. In one embdiment of the present invention, theair chambers central groove section 74 is defined by (i.e., between) the twoair chambers central groove section 74 can be made from a material (e.g., PVC) that provides sufficient strength and rigidity to separate and support the twoair chambers air chambers central groove section 74 can be made from the same material, PVC. Theair chambers valves chambers - Referring to FIG. 3, the
water inlet 30 is a short tubing that extends through thecentral groove section 74 to communicate with the interior 34 of thepool 22. Agasket 82 is provided over theinlet 30 adjacent theinner wall 84 of thecentral groove section 74. In addition, thewater outlet 32 includes a tubing orpipe 86 that can be made, for example, from a hard material such as PVC. The outer end of thepipe 86 communicates with thewater outlet 32, and the inner end of thepipe 86 communicates with the interior 34 of thepool 22 via anopening 88. Onegasket 82 can be provided over the outer end of thepipe 86 in the interior of theair chamber 72 adjacent thewater outlet 32, and anothergasket 82 can be provided over the inner end of thepipe 86 in the interior of theair chamber 72 adjacent theopening 88. A strainer 90 can be positioned in front of theopening 88 inside the interior 34 to collect or filter debris and other particles to prevent these particles from being transported to the pump andheater unit 28. Thegaskets 82 can be any conventional gasket, or can be thenovel gasket 82 described hereinbelow in connection with FIG. 14. Thegaskets 82 function to provide a tight seal against water leakage from theinterior 34 of thepool 22. The fact that thewater inlet 30 and thewater outlet 32 are the only two openings which communicate the interior 34 to the outside, coupled with the provision of the novel andeffective gaskets 82, further minimize against the possibility of water leakage This is to be contrasted with conventional spa pools that provide more than two such openings which communicate the interior of the spa pool to the outside. Such conventional spa pools often experience annoying water leakages from these numerous openings. - Referring to FIG. 4, which is an enlarged view of the
water outlet 32, a drain cock assembly is provided to allow water to be drained from the interior 34. The drain cock assembly has adrain cock 94 that extends from the tubing of thewater outlet 32, astopper 96 that is fitted at the end of thedrain cock 94, and acap 98 that can be threadably screwed over thedrain cock 94 to seal it. To drain water from the interior 34, thecap 98 andstopper 96 can be removed, and ahose 100 threadably screwed to thedrain cock 94 to divert the water to the desired disposal destination. Thehose 100 does not need to be used when thespa pool assembly 20 is used outdoors, since the water can be drained directly from thedrain cock 94. However, if thespa pool assembly 20 is used indoors, thehose 100 can be coupled to thedrain cock 94 and directed outside the house to drain the water from thespa pool 22. An on/off valve control 101 can be provided ondrain cock 94, with an on/off ball valve (not shown) provided inside thedrain cock 94. The control 101 allows the user to turn off the valve when disconnecting the hose 100 (i.e., water to be diverted into the pool 22), and to turn on the valve when thehose 100 is connected (i.e., water to be drained). - The plumbing system is illustrated in greater detail in FIGS. 3, 5 and6. The plumbing system includes a plurality of
jet nozzles 110, and a plurality ofair hoses 112 andwater hoses 114 that interconnect thejet nozzles 110 in the manner illustrated in FIG. 5 to extend annularly around thepool 22. Eachhose hoses water hoses 114 can be provided in the form of pipes that are made of hard PVC, metal or other hard materials. Thehoses hoses jet nozzles 110 shown in FIG. 5 is intended to be retained inside thecentral groove section 74. Eachjet nozzle 110 is retained in anozzle housing 116. Eachjet nozzle 110 can be any conventional jet nozzle that is currently available and used for conventional spa pools. For example, two types ofjet nozzles 110 can be used: a water flow adjustable nozzle and a non-adjustable nozzle. The jet nozzles 110 can also be one-directional, or multi-directional that are adjustable by the user to massage different areas of the user's back. - Referring to FIGS.5-7, the
nozzle housing 116 has twoside plates parallel plates nozzle housing 116 can be designed to withstand 200 pounds compression pressure, just in case someone sits or stands on anindividual housing 116. Theside plates central groove section 74. A T-connector 126 is retained (e.g., by rivets, snap-fit, glue or screws) inside the space defined by theplates plates connector 126 has acentral tubing 128 that is connected to thejet nozzle 110. A water-tight gasket 111 is provided between thecentral tubing 128 and thejet nozzle 110 to prevent water from leaking into thepool 22 from thenozzle housing 116. The T-connector 126 has twobranch water tubings 130 that extend in opposite directions from thecentral tubing 128, and two branch air tubings 132 that also extend in opposite directions from thecentral tubing 128. Eachbranch tubing flange flanged connector end water hose 114 and anair hose 112, respectively. As best shown in FIG. 6, eachend water hose 114 and anair hose 112, respectively, has alock nut hoses end flanged connector connectors ends lock nuts hoses flanged connectors flanges lock nuts flanges - Referring back to FIG. 5, the
jet nozzles 110 can be spaced apart in an annular and opened configuration. A T-connector 150 can be provided at the location of thewater inlet 30 to connect twoadjacent water hoses 114. Similarly, another T-connector 152 can be provided to connect twoadjacent air hoses 112 with atubing 154 that extends through thesecond air chamber 76 to anair control 156. Screw-in plugs or two-way T-connectors can be used to seal the two end or terminal nozzles 110 e to prevent water and air from leaking out. The jet nozzles 110 can also be spaced apart in an annular and closed configuration as illustrated in FIG. 8. - FIGS. 9 and 10 illustrate one non-limiting method of attaching each
jet nozzle housing 116 to theinner wall 84 of thecentral groove section 74. Therear plate 120 of thehousing 116 can be provided with a key-shapedopening 160 having a generallycircular sub-opening 162 and a smallerelongated sub-opening 164. A plurality ofconnectors 166 can be provided in spaced-apart manner around theinner wall 84. Eachconnector 166 is adapted to connect onejet nozzle housing 116, and includes athin shaft 168 and an enlarged orbulbous end 170. To achieve the connection, thebulbous end 170 is inserted through thecircular sub-opening 162, and then theconnector 166 slid with respect to therear plate 120 in a manner so that theshaft 168 is received inside theelongated sub-opening 164. When theshaft 168 is retained inside theelongated sub-opening 164, thebulbous end 170 cannot be removed because it is larger than theelongated sub-opening 164, thereby creating the connection. To remove thejet nozzle housing 116 from theconnector 166, theconnector 166 is slid with respect to therear plate 120 in a manner so that theshaft 168 is moved back into thecircular sub-opening 162, where thebulbous end 170 can be removed from thekey slot opening 160. - Although FIGS. 9 and 10 illustrate one method of attaching each
jet nozzle housing 116 to theinner wall 84 of thecentral groove section 74, other similar connection schemes can be used to achieve the same connection. For example, any male-type connector (such as connector 166) can be provided in a spaced-apart manner about the annularinner wall 84, and releasably connect any opening or other female-type receptor provided in therear plate 120 or any other part of thehousing 116. - FIGS. 11 and 12 illustrate the pump and
heater unit 28 in greater detail. Theunit 28 has acasing 178, with awater outlet 180 that is adapted to be connected to thewater inlet 30, and awater inlet 182 that is adapted to be connected to thewater outlet 32. Thecasing 178 houses amotor 184, apump 186 mounted on and controlled by themotor 184, and aheater 188. Theheater 188 can be automatically activated by a water pressure sensor (built into the heater) which turns on theheater 188 when water begins to travel through it. Theheater 188 can also be provided with an automatic maximum temperature cut-off if the water reaches a pre-selected maximum temperature (e.g., 104 degrees Fahrenheit). Anair button 190 extends from outside thecasing 178 and is coupled to themotor 184 via avacuum tube 185. Theair button 190 functions to turn on theheater 188 and the pump 186 (by operating the motor 184), and is used to provide additional safety to the user because the user is not exposed to any electrical components when turning on and off thepump 186. One ormore grills 192 are provided on thecasing 178 to function as a vent for allowing cool air to enter thecasing 178 to cool themotor 184, pump 186 andheater 188. In addition, a cooling fan (not shown) can be mounted in the rear of thecasing 178 to cool themotor 184, pump 186 andheater 188. Apower cord 194 extends from themotor 184 through thecasing 178.Handles 198 can be provided on thecasing 178 to allow the user to lift and carry theunit 28. As one non-limiting example, theunit 28 can be embodied in the form of the PS-1 System marketed by Spa Builders System Group. - In operation, water from the
water outlet 32 of thepool 22 enters from theinlet 182 and is pumped by thepump 186 through theheater 188 and then out through theoutlet 180 to be delivered via thewater inlet 30 of thepool 22 to the interior 34 of thepool 22. - Referring to FIG. 13, a carrying
case 200 can be provided to store the pump andheater unit 28 and the dis-assembled components of the portablespa pool assembly 20. Thecase 200 has a hingedcover 202 to cover acontainer body 204. Ahandle 206 can extend from oneend 208 of thecontainer body 204, and a set ofwheels 210 can be provided adjacent anotherend 212 thereof so that a user can pull the fully-loadedcase 200 like pulling a piece of luggage. Thecontainer body 204 defines aninterior space 214 that is large enough to fit the pump andheater unit 28, and the dis-assembled components of the portablespa pool assembly 20. Theinterior space 214 can even be divided intoseparate compartments 220 and 222 (with thedivider 224 shown in phantom in FIG. 13) so that theunit 28 can be securely stored in onecompartment 222, and the other components in theother compartment 220. - The assembly and operation of the portable
spa pool assembly 20 will now be described. The user can unload all the disassembled components of the portablespa pool assembly 20 from thecase 200 if thecase 200 is provided. The pump andheater unit 28 can be removed from thecase 200, or retained inside thecase 200. Thespa pool 22 is then inflated by inflating the twoair chambers water inlet 30 is then coupled to thewater outlet 180 of the pump andheater unit 28, and thewater outlet 32 is then coupled to thewater inlet 182 of the pump andheater unit 28. The strainer 90 can be fitted over theopening 88. The plumbing system is then assembled to the configuration shown in FIG. 5 or FIG. 8, by attaching thehoses jet nozzle housings 116 in the manner described above. Thereafter, eachjet nozzle housing 116 is secured to theinner wall 84 of thecentral groove section 74 at the locations of theconnectors 166 according to the techniques illustrated in connection with FIGS. 9 and 10. The T-connector 150 is then connected to thewater inlet 30, and the T-connector 152 is connected to theair control 156. At this time, the plumbing system would be secured inside thecentral groove section 74. Theliner 24 and cover 26 can then be placed over thepool 22, in the manner shown in FIG. 2. When theliner 24 and cover 26 are placed into the interior 34 of thepool 22, the user must be careful to align the openings 40 (in the liner 24) and 62 (in the cover 26) with thejet nozzles 110. In addition, thecover 26 should not block the strainer 90 or theair control 156. The assembly is now complete, and as shown above, can be done very quickly and conveniently. Water can be filled into the interior 34 to the required water level, and thepump 186 primed by drawing water from thepool 22 into thepump 186. Since there are no obstructions between thepump 186 and the water, the water flows naturally into thepump 186 when water is filled to the desired level in thepool 22. Once thepump 186 has been primed, thepump 186 is ready to begin recirculating water. Thespa pool assembly 20 is now ready for use. - To use the
spa pool assembly 20, the user plugs in thepower cord 194 to a power source, and then turns on themotor 184 by actuating theair button 190. Since thepump 186 has been primed, water can be drawn through the strainer 90 andopening 88 through thetubing 86 and into thepump 186. The water is then pumped through theheater 188 and via thewater outlet 180 andwater inlet 30 to thewater hoses 114 and delivered to eachjet nozzle housing 116, where the water can be ejected from each correspondingjet nozzle 110. Theheater 188 is automatically turned on when water begins to circulate through the system. The water is re-circulated in the same manner. - Air bubbles can be ejected through each
jet nozzle 110 due to an air pressure system. Specifically, theair control 156 is like an air inlet, and it couples theair hoses 112 to the ambient. The user can control the amount of air that enters the air control, so as to create an air pressure that is lower than the water pressure. Air is drawn from vacuum created by the high water pressure, so the lower air pressure and higher water pressure will cause air bubbles to be generated where the air meets the water in the central tubing 128 (as shown in FIG. 7), and then delivered via thejet nozzles 110 to the interior 34 of thespa pool 22. - To dis-assemble the
spa pool assembly 20, the user turns off themotor 184, and disconnects all the components by reversing the steps described above. Theair chambers case 200. During dis-assembly, it is important to note that the plumbing system can be installed into or taken out of thespa pool 22 without deflating thespa pool 22. - The present invention also provides a
unique gasket 82 that is illustrated in FIG. 14. Thegasket 82 further minimizes the possibility of leakage of water from the interior 34. Thegasket 82 is provided to seal and secure portions of tubing, and even though thetubing 86 is illustrated in FIG. 14, the same principles illustrated in FIG. 14 can be utilized for any of theother gaskets 82 shown in FIG. 3. Thetubing 86 is preferably a hard tubing (e.g., made from hard PVC) that is injection-molded and provided with grooves orribs 228 to provide an uneven (i.e., non-smooth) surface. The grooves orribs 228 are positioned adjacent theinner wall 84 where leakage is most likely to occur. Thegasket 82 is made from a soft material, such as soft PVC, which is then injection-molded and bonded directly over thetubing 86 on to the surface of thetubing 86. Since both thetubing 86 and thegasket 82 are made from the same material (PVC), this process creates a homogeneous bond that is essentially one material. To provide further protection against leakage, thegasket 82 can be formed with twoannular side flanges tubing 86 away from the location of theinner wall 84. Thegasket 82 functions not only to prevent water leakage, but also to secure thetubing 86 at a designated location. Although PVC is used as an example for the material for thegasket 82 and thetubing 86, other materials can also be used, such as but not limited to metal, rubber or plastics. - FIG. 15 illustrates a modification to the
air chambers chambers air chamber inner tube air chamber Respective valves air chambers pool 22, through which air can be introduced to inflate theinner tubes valves pool 22, it is also possible to have thevalves pool 22. - As illustrated above, the
spa pool assembly 20 of the present invention provides a number of benefits. First, the provision of only two openings (inlet 30 and outlet 32) between theinner wall 84 of thepool 22 and theouter wall 85 of thepool 22 minimizes the possibility of water leakage from the interior 34, when compared with other spa pools that provide more than two such openings. Second, by providing all components of the plumbing system inside thepool 22, any leakage or malfunction of the plumbing system will again minimize the possibility of water leakage outside thepool 22. Third, three layers of thewall 70, theliner 24 and thecover 26 provide three levels or layers of protection against leakage and other damage to thepool 22. Fourth, thenovel gasket 82 provides an effective seal that further minimizes the possibility of water leakage. Fifth, the fact that the plumbing system can be installed into or taken out of thespa pool 22 without deflating thespa pool 22 adds to the convenience for the user, since defective parts can be easily replaced without the need to completely dis-assemble thespa pool 22. Sixth, the assembly and dis-assembly steps illustrated above are quick and easy, and do not require the use of special tools, thereby allowing thespa pool assembly 20 to be moved about for use in many different locations. Seventh, all the components in thespa pool assembly 20 are modular in that one defective part or component can be easily replaced without replacing other functioning components. - While the description above refers to particular embodiments of the present invention, it will be understood that many modifications may be made without departing from the spirit thereof. The accompanying claims are intended to cover such modifications as would fall within the true scope and spirit of the present invention.
