Description

MODULAR THERAPY SYSTEM WITH TEMPERATURE CONTROL, STERILIZATION, AND FILTRATIONPRIORITY

[0001] This application claims the benefit of priority to U.S. Provisional Application No. 63 / 550,923, filed February 7, 2024, which is incorporated in its entirety into this application.BACKGROUND

[0002] Traditional spa therapy was originally through natural means such as natural outdoor hot springs, sunlight exposure, cold water creeks and streams, snow / ice and sun warmed surfaces on the ground like rocks and sand. Modem day humans are indoors for much of their life leading to a reduced exposure to these traditional spa-type modalities found in nature. Commercial retail and experience type businesses exist to offer similar spa-type experiences indoors, such as, for example, the following popular solutions: indoor spas with sauna’s, natural hot springs retreats, bath houses, cold water pools and baths and light therapy.

[0003] These commercial solutions often require abundant chemicals to filter, clean and stabilize the water for repeated use and from many individuals can use the facilities in a safe way. Commercial solutions are often expensive to build, set up and run, often making them inaccessible to the end users as a personal or in-home solution. Current in-home solutions developed to meet these therapeutic needs previously sought out through the outdoors, and more recently through indoor businesses recreating these therapeutic modalities, includes such things as reusing bathing tubs but adding chilled water for cold exposure therapy, installing hot sauna’s, hot tubs, pools, and red-light therapy products. Such products are often set up in homes, garages or on patios.

[0004] However, these current in-home solutions also require significant investment in building and setting up, and are either permanently installed or at least difficult to move once built. Further, current in-home solutions do not offer a natural experience which is one of user’s primary desires for the products. Many of these solutions use ozone filtration and chemical additives which can be toxic to human health. Additionally, they employ materials which off-gas and leach chemicals into the water, which has been shown to have adverse effects on human health. Novel methods of offering pieces of this desired therapy have been exploredby other businesses and inventors, but it has all resulted in either poor performance and results, or a very high price.

[0005] What is needed therefore is a system that provides such spa-type modalities in a light weight and portable system. The system is compact and easy to transport which saves on shipping costs, and is quick and easy to build by the end user. The system is of a modular construction allowing the user to modify the system to their personal preferences as well as allowing to easily change, replace or upgrade components as needed. Further, the system uses UV light and carbon filtering elements configured to mitigate the use of various harmful chemicals required to cleanse the water used in the systems.SUMMARY

[0006] In an aspect of the invention, the system allows for otherwise bulky therapy products to be shipped direct to the end user, rather than expensive and inconvenient freight shipping which is the industry standard. After brief assembly processes the users experience premium full-sized therapy. Normally large trucks, forklifts or crews of delivery and installation workers are required to install and assemble full-sized therapy tubs and sauna.

[0007] In an aspect of the invention, the system is easy to clean and maintain. For example, draining of traditional cold and hot therapy tubs requires users to have the unit installed outdoors where water can drain out from tub directly. They also traditionally require users wait for the tub to drain via gravity. They also require users to clean up any pockets of used water after draining as the tubs are not consistently sloped towards the drain, leaving puddled used water.

[0008] In an aspect of the invention, a built-in drain valve with hose fitting would allow users to install the tub in locations where draining would not be possible without a hose, and the water is propelled through the hose with the built-in water pump to speed up draining would also be desirable.

[0009] Traditional cold and hot therapy tubs, often employ a power consuming chiller or heater which have loud fans and condensing units. Traditional cold and hot therapy tubs, saunas, etc. require a 240-volt 30-amp power outlet to operate. Further, such units are installed with little insulation, or are insulated but result in a very heavy tub construction, neither of which are convenient for users. In an aspect of the invention, the system uses low powerheating and cooling units, which run quietly and are well insulated. The system runs from 120- volt 15-amp power outlets providing increased flexibility for installation.

[0010] Historically cold, heat and light therapy products are designed and purchased and work independently, resulting in high cost and poor configuration options for users looking for “contrast therapy”. Given the lower costs for end users of the unique direct home deliverable and easy to configure designs, users can purchase multiple products and configure them together in their homes or business to achieve multiple therapeutic modalities as needed. Features like towel racks, device holders, drink holders, seating and storage, benches, multifeature tub lids, warming floor mats, comfort head rests and other system features and accessories allow for improved user experiences. For example, there is a need that exists today for cold plunging or ice bathing which stores the users towels for use and has drying racks. A towel is an essential part of the experience but has rarely been considered in the design of a cold plunge product. Similarly, users often change in and out of warmer clothes before and after use of the therapeutic plunge system, so a shoe and clothing storage area plus bench to sit, rest, put on shoes, is highly beneficial to the user’s experience. These and additional aspects are addressed in the foregoing.

[0011] In an embodiment of the invention, a tub, sauna, lighting and related cooling, heating, and plumbing parts can be assembled to create cold tubs, warming tubs, sauna, lighting, and warmth therapy system.

[0012] In an embodiment of the invention, various configurations of cold or heat therapy products can be set up together in multiple configurations in order to offer comfortable and convenient “contrast therapy” for users looking for various mental, health and wellness benefits.

[0133] FIG. 6D shows and exemplary fluid pathway of the water from the outlet 170 through the control unit 150 to the inlet 172. As shown, the fluid flows from the outlet 170 through the water pump 162, through one or more of the UV filter 160 and the carbon filter 168 before entering the heat pump unit 164. At the heat pump unit 164, the water temperatureis modified to the desired temperature before entering the tub 110 by way of the inlet 172. As will be appreciated, however, other configurations of fluid flow are contemplated. Advantageously, the distance between the heat pump unit 164 outlet and the inlet 172 is minimized to mitigate temperature change of the fluid before entering the tub 110. Advantageously, the UV filter 160 and carbon filter 168 filters and kills organic matter while greatly reducing requiring chemical water treatments or similar additives for sterilizing the water. This reduces the exposure to the user to various chemical water treatments, prolonging the user experience.

[0134] In an embodiment, the water circuit in the control unit 150 includes a tap configured to allow water from the tub 110 to be actively pumped out of the system 100, by way of the water pump 162. Advantageously, this allows the water to be emptied from the recess 118 quickly by using the water pump 162 to empty the water faster than would otherwise be possible by a gravity flow. In an embodiment, the tub 110, 310 can include a drain aperture 282 that provides fluid communication through a wall thereof to allow for the tub to be emptied by a gravity flow. (FIG. 19E).Packaging and transportation

[0135] FIGS. 7-8F show further details of the system 100 in a packaged configuration to provide compact configuration for transport and storage. FIG. 7 shows a cross section view of the system 100 in a packaged configuration ready for transport and storage. As shown, the control unit 150 is sized to fit within the recess 118 of the tub shell 112. In an embodiment, the lid 140 can fit within the recess 118 and can be closed therein by attaching a packaging cover over the recess 118 and securing in place using the screw holes 124.

[0136] In an embodiment, control unit 150 and other components (e.g., cables, pipes, unions, etc.) can be closed within the recess 118 and lid 140 can be secured over the recess 118 using the screw holes 124. In an embodiment, the outer dimensions of the control unit shell in a constructed state are configured to fit within the recess 118.

[0137] FIGS. 8A-8F shows the tub shell 112 and a first extension 130A in both a constructed configuration and a packaged configuration. In an embodiment, the one or more extensions 130 can be nested on an outside of the tub shell 112 to provide a compact, packaged configuration. FIG. 8A shows a lateral cross section of the tub shell 112 having the first extension 130A in the constructed configuration shown in dashed, and in the nested packagedconfiguration in solid. FIG. 8B shows a plan view of the tub shell 112 and first extension 130A in the nested, packaged configuration. FIG. 8C shows a lateral cross section of the tub shell 112 and first extension 130A in the constructed configuration. FIG. 8D shows a longitudinal cross section of the tub shell 112 and first extension 130A in the constructed configuration. FIG. 8E shows a lateral cross section of the tub shell 112 and first extension 130A in the packaged configuration. FIG. 8F shows a longitudinal cross section of the tub shell 112 and first extension 130A in the packaged configuration.

[0138] In an embodiment, the first extension 130A can be removed from the rim 120 of the tub shell 112 and the tub shell 112 can be lowered into the first extension 130A. Optionally the tub shell 112 and first extension 130A assembly can then be lowered into the second extension 13 OB. Similarly, the tub shell 112, first extension 130A and second extension 130B assembly can then be lowered into the third extension 130C. In this way the tub shell 112, first extension 130A, second extension 130B, third extension 130C, etc. can be fitted together in a nested configuration to provide a compact configuration for transport and storage.

[0139] In an embodiment, the outer surface of the tub shell 112 and the inner surface of the extension 130 are angled relative to the vertical axis to allow the tub shell 112 to nest inside the extension 130 during the packaged configuration but also allows the bottom edge of the extension to engage the rim 120 in the constructed configuration.

[0140] FIGS. 9A-9B show a cross-section view of an exemplary connection 252 between the rim 120 of the tub shell 112 and the bottom edge of the first extension 130A. FIG. 9B shows close-up detail of the connection 252 of FIG. 9 A. In an embodiment, the rim 120 of the tub shell 112 includes a lower engagement surface 254 and the bottom edge of the extension 130, e.g. the first extension 130A, includes an upper engagement surface 256. The lower engagement surface 254 extends at an angle relative to the horizontal axis wherein a lower edge of the lower engagement surface 254 is disposed inwards towards the tub recess 118.

[0141] At a first end of the engagement surface 254 nearest the recess 118, the engagement surface 254 includes a first lip 258. Optionally, a second end of the lower engagement surface 254, opposite the first end and furthest from the recess 118, i.e. towards an outside of the tub, can further include a second lip 260. The upper engagement surface 256 also extends at an angle relative to the horizontal axis and is configured to match the angle ofthe lower engagement surface 254, i.e. a lower edge of the upper engagement surface 256 is disposed inwards towards the tub recess 118. The lower edge of the upper engagement surface 256 further includes a first bevel 262 configured to engage the first lip 258. Further, the upper edge of the upper engagement surface 256 further includes a second bevel 264 configured to engage the second lip 260.

[0142] Advantageously, the inwards angle of the lower engagement surface 254 and the upper engagement surface 256 causes the weight of the extension 130 to force the upper engagement surface 256 inwards, pushing against the rigidity of the extension 130 and forming a tight seal between the lower engagement surface 254 and the upper engagement surface 256. Further, the first bevel 262 engages the first lip 258 to prevent the inner edge of the upper engagement surface 256 from sliding too far inwards and misaligning with the lower engagement surface 254. Further, the second bevel 264 can engage the second lip 260 to further guide and align the upper engagement surface 256 with the lower engagement surface 254.

[0143] In an embodiment, one or both of the upper engagement surface 256 and the lower engagement surface 254 can include a connection gasket 266. The connection gasket 266 can include an annular seal formed of a polymer, elastomer, rubber, silicone rubber, or the like and disposed between the upper engagement surface 256 and the lower engagement surface 254 to form a watertight seal therebetween. Optionally, one or both of the upper engagement surface 256 and the lower engagement surface 254 can include a groove, extending annularly along the surfaces 254, 256 and configured to receive a portion of the connection gasket 266 therein. Advantageously, the weight of the extension 130 can compress the connection gasket 266 to for a watertight seal and allow the water level within the recess 118 to extend above the connection 252.

[0144] In an embodiment, the connection 252 can further include one or more fasteners 268 configured to releasably secure the upper engagement surface 256 and the lower engagement surface 254 together. For example, as shown, the lower engagement surface 254 can include one or more screw holes, for example screw hole 124. Further, the upper engagement surface 256 can include one or more female threaded engagements 126 that align with the one or more screw holes 124. A screw or bolt can extend through the screw hole 124 and engage the female threaded engagement 126 to releasably secure the upper engagement surface 256 and the lower engagement surface 254. As will be appreciated, other mechanicalfastenings are also contemplated that are configured to releasably secure the upper engagement surface 256 and the lower engagement surface 254 together.

[0145] Advantageously, the bolt 128 does not extend all the way through the extension 130 to provide a smooth inner wall to the extension 130 and mitigate areas which may leak. Further, as shown, when the connection 252 is engaged, the inner surface of the extension 130 and the inner surface of the tub shell 112, co-operate to provide a smooth profile.

[0146] As will be appreciated, the connection 252 as described herein can be disposed between the rim 120 of the tub shell 112 and the lower edge of the first extension 130A. Further, the engagement between the lower edge of the second extension 130B and the upper edge of the first extension 130A can also include a connection 252 as described herein. Similarly, the engagement between additional extensions 130 can also include a connection 252 as described herein. In an embodiment, an inner surface of the extension 130 disposed adjacent the connection 252 can extend inwards and provide an arm rest 178 extending annularly about an inner surface of the recess 118.Modular construction of control unit
