SUBMERSIBLE FOOT MASSAGER FOR USE IN HYDROTHERAPY HOT TUBS
BACKGROUND OF THE INVENTION
The field of the invention generally pertains to massaging
devices. The invention relates more particularly to a
6 submersible foot massaging system for use in hydrotherapy hot
7 tubs.
Various types of spa massagers have been utilized in
hydrotherapy hot tubs or whirlpool baths to therapeutically
1o enhance the bathing experience, and to promote health and well-
11 being. They do so by soothing and relaxing sore, stiff muscles,
12 and by relieving tension and stress around the various body
13 parts. One such massaging apparatus is shown in U.S. Pat. No.
14 5,984,883 particularly for massaging a person's neck while seated
1s in a hydrotherapy hot tub. However, because of its fixed
16 position typically against a sidewall of the hydrotherapy hot
tub, this and other similar conventional spa massaging units are
18 generally limited to targeting the neck, shoulder, and back areas
19 of a bather. Other lower parts of the body, such as the thighs,
zo calves, and feet are unable to be similarly massaged in a
1 comfortable manner.
'-2 Arguably, the feet may experience the most aches, pains and
'-3 soreness at the end of a work day or week because of its focal
1
CA 02340285 2001-03-09




133/07
1 role in supporting the entire bony. Thus, in an effort to target
2 the feet in particular, various conventional foot massagers have
3 been developed, such as by employing a vibrating solid object in
4 a dry massage or administering a hydromassage in a self-contained
water medium. One example of such a conventional non-spa foot
6 massager is shown in U.S. Patent No. 3,965,495 disclosing a
7 hydrotherapy foot tub for containing water. A user's feet may be
8 immersed in the tub of water, and vibrations generated through
the water to effectuate the massage. Unfortunately, however,
1o such conventional foot massagers are typically not designed for
11 use in hydrotherapy hot tubs where a bather may enjoy the
12 combined and simultaneous massaging effects of the foot massager
13 and the hydrotherapy hot tub. In particular, they are not
14 designed for submersible underwater use in a body of water,
particularly because of the presence of on-board electrical
15 massager motors and controller components of a self-contained
17 massage operating system. Thus, the relaxing comfort and
1s benefits derived from a readily accessible hot tub or whirlpool
19 bath may typically not be realized in combination with the
2o therapeutic benefits of a foot massager.
21 In U.S. Patent No. 4,184,488, however, one such foot
22 massaging device is shown for use in a bathtub. The foot
23 massaging device is connected to a faucet of a bathtub and water
24 is conducted to the foot massaging device to exert a hydrotherapy
massage on the feet. In this example, a user may experience the
CA 02340285 2001-03-09




133/07
restf,?1 and therape,~tic bE;,efiis of being immersed in a warm body
2 of water while additionally being massaged along the feet.
3 However, due to its polycarbonate plastic composition, this foot
massaging device may have a tendency to buoy up to the surface
which must be manually checked with a downward force using one's
5 hands or feet. Thus, without providing some means for submerging
7 the device and keeping it submerged, such buoyancy may detract
8 from the relaxed and restful atmosphere originally intended.
In summary, therefore, a foot massager which is particularly
1o designed for use in a hydrotherapy hot tub or spa would be
11 desirable to further enhance the hydrotherapy bath experience.
12 It is important that the foot massager be self-sufficiently
13 maintainable underwater in order to exert a massage on a bather's
14 feet without requiring user intervention. Otherwise, it would be
i5 frustrating and counter-productive to the hydrotherapy experience
to have to constantly deal with a buoying foot massager.
17 BRIEF SUMMARY OF THE INVENTION
18 It is an cbject of the present invention to provide a foot
19 massager for use in hydrotherapy hot tubs and whirlpool baths
2o which may be maintained under water in a self-sufficient manner
21 to therapeutically massage the feet of a bather while the rest of
22 the bather simultaneously enjoys the benefits of relaxing in the
23 hydrotherapy hot tub.

1 It iS a further object pf the preSciit inveiitiun t0 provide a
2 foot massager employing the water jets and water pumps employed
3 by such hydrotherapy hot tubs and whirlpool baths for actuating
the massage in a non-electric manner.
s The present invention is for a foot massaging system for use
in a hydrotherapy hot tub. The foot massaging system comprises a
massager unit which has a rigid shell having at least one, and
s preferably two, massager openings. The massager unit also has
massager means movably secured to the rigid shell for imparting
1o an undulating perturbance through the at least one massager
11 opening when the massager means is actuated. Furthermore, the
12 massager unit has a turbine drive which is fixedly secured to the
13 rigid shell and which is dynamically connected to the massager
14 means so that rotation of the turbine drive actuates the massager
is means. The massager unit also has submersion means for
16 maintaining the massager unit against an underwater surface in
17 the hydrotherapy hot tub by overcoming the. buoyancy of the
is massager unit. The foot massaging system also comprises a fluid
19 pump which is driven by a pump motor. The fluid pump has a pump
2o inlet which is supplied to a body of fluid, and a pump outlet.
21 Furthermore, the foot massaging system has an inlet hose which
22 connects the pump outlet of the fluid pump to an inlet port of
23 the turbine drive. This arrangement causes rotation of the
24 turbine drive and actuation of the massager means.

5 at least one massager opening when the drive shaft and the at
least one hub portion are rotated. Furthermore, the plurality of
a nubs are preferably a plurality of rollers which are rotatably
mounted on the at least one hub for providing a rolling massaging
1o contact. With this arrangement an undulating perturbance and
11 massage is provided by the nubs, i.e. rollers, through the at
12 least one opening of the rigid shell when the turbine drive
13 rotates the drive shaft.

13 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
14 Referring now to the drawings, Figures 5 and 6 show the
15 component parts of the foot massaging system, generally indicated
16 at reference character 10, which is installed in a hydrotherapy
hot tub or whirlpool bath, generally indicated at reference
1$ character 11. The hydrotherapy hot tub 11 preferably is of the
19 type having a chair-like seating configuration, with a tub
zo sidewall 14 functioning as a backrest, a seat portion 14', and a
?1 floor surface 13. Furthermore, the hydrotherapy hot tub 11 has a
'.2 plurality of jet nozzles 21 along said tub sidewall 14 through
'-3 which streams of water and/or air may be pumped for providing an
'4 effervescent therapeutic force against a bather's body. The
6
CA 02340285 2001-03-09




133/07
1 water and/or air is pumped into the hydrotherapy hot tub 11 by
2 means of a fluid pump l5, which will be discussed in detail
3 below.
4 The primary component of the foot massaging system 10 is a
massager unit, generally indicated at reference character 25.
5 The massager unit 25 may be placed inside the tub 11 together
7 with a bather (not shown) such that the bather may experience a
s foot massage by placing his/her feet on the massager unit 25. As
9 shown in Figures 5 and 6, the massager unit 25 is submersibly
1o positioned underwater in the hydrotherapy hot tub 11 along a
11 horizontal surface thereof. Ideally, the horizontal surface is
12 the floor surface 13 of the hydrotherapy hot tub 11 such that a
13 user may ergonomically and comfortably rest his/her feet upon the
14 massager unit 25 while seated on the seat portion 14'. However,
1s the massager unit 25 may alternatively be relocated to any
desired horizontal surface of the hydrotherapy hot tub 11 where
17 it may come to rest while submerged underwater.
1s Details of the massager unit 25 can be seen in Figures 1
19 through 4. In particular, Figure 1 shows a general perspective
2o view of the massager unit 25, as finally assembled. The massager
21 unit 25 has a rigid hollow body or shell 26 preferably
22 constructed of two halves, an upper body portion 27 and a lower
23 body portion 36. Preferably the lower body portion 36 is the
24 frame upon which the internal mechanics of the massager unit 25
2s are secured, and the upper body portion 27 provides a cover for

1 said iia ter iaai mec haiaicS . i'~owev2r , i t iS no t iii«i t~'d oiaiy tC
2 such. It is notable that the designations of frame and cover may
3 be interchangeable, e.g. by securing the internal mechanics of
4 the massager unit 25 to the upper body portion 27. In any case,
the upper body portion 27 has an upper body rim 38 which is
6 adapted to be detachably connected to the lower body portion 36
7 along a lower body rim 37. An illustrative example of this
connection is shown in Figure 2 of the drawings. It is further
9 notable that the rigid body 26 has inlet 39 and outlet 40
1o apertures (see Figures l, 3, 7, and 8) which enables entry into
11 and egress out of the rigid body 26. In particular, the inlet
1z aperture 39 enables access to the turbine inlet port 49 of the
13 turbine drive 47, and the outlet aperture 40 enables exhaust from
14 the turbine outlet port 50 of the turbine drive 47 to exit the
rigid body 26.
15 And as can be best seen in Figures 1 and 2, the upper body
17 portion 27 has a generally inclined configuration formed by left
Za and right upper deck surfaces 31 and 34 with adjacent massager
19 openings 29 and 32, respectively. A ridge portion 35 divides the
left and right upper deck surfaces 31 and 34 in order to
21 spatially accommodate a turbine drive (see 47 in Figure 3) inside
22 the rigid body 26. The massager openings 29 and 32 enable
23 suitable massager means, such as a roller assembly 41, to
24 partially protrude therethrough to effect the massage (see
detailed discussion below). While two massager openings 29 and
s

k
1~J~O~
32 are shown in the drawings for effecting massages to the left
2 foot and right foot separately, it is appreciated that a single
3 elongated massager opening (not shown) or more than two massager
4 openings may alternatively be employed. In any case, the
inclines of the left and right upper deck surfaces 31 and 34
6 provide an ergonomic configuration whereupon a user may rest a
part of his/her feet while another part is being massaged at the
s massager openings 29, 32. It is notable that the left and right
massager openings 29 and 32 are preferably covered with left and
1o right diaphragms 30 and 33, respectively, such that the massager
11 means imparts the massage through the diaphragms 30, 33. The
12 diaphragms 30, 33 are preferably fabricated from a flexible
13 waterproof material such as an elastomer like polyurethane. It
14 is further notable that the rigid hollow body 26 is preferably
constructed from a rigid polycarbonate plastic material. While
15 such materials are generally known to exhibit buoyant
m characteristics in a water medium, this may be overcome by
18 providing means for maintaining the massager unit 25 underwater,
1g as will be discussed in greater detail below.
2o As can be best seen in Figure 3, the lower body portion 36
21 preferably serves as a base or frame upon which the internal
22 mechanical components of the massager unit 25 are secured. In
23 particular, the massager unit 25 has a turbine drive, generally
24 indicated at reference character 47, comprising a turbine housing
48 with turbine inlet 49 and outlet 50 ports. The turbine
Q
CA 02340285 2001-03-09




133/07
1 housing 48 encloses a turbine flywheel (not shown] adapted to
2 rotatably engage a-fluid flow entering the turbine inlet port 49
3 and exiting the turbine outlet port 50. And the turbine flywheel
4 is connected to a turbine drive shaft 51 (Figure 4j such that
rotation of the turbine flywheel causes the turbine drive shaft
6 51 to also rotate.
Generally, rotation of the turbine drive 47 is adapted to
8 actuate the massager means whereby the massager means may impart
the undulating perturbance through the at least one massager
to opening 29, 32 to effect the massage. More particularly,
11 however, as shown in Figures 3 and 4, transfer of power from the
12 turbine drive 47 to the massager means, i.e. roller assembly 41,
13 is preferably via a transmission unit, generally indicated at
14 reference character 53. Figure 4 in particular shows the details
of the drive train with the transmission unit 53 exposed. As can
16 be seen, the transmission unit 53 comprises a transmission
1~ housing 54 which encases a series of gears 55. The turbine drive
18 shaft 51 of the turbine drive 47 dynamically engages the gears 55
19 via a turbine pinion gear 52 such that a final reduction gear 56
2o may be rotated. Preferably, the final reduction gear 56 engages
21 a drive gear 46 which is fixedly secured to the drive shaft 42 of
22 the roller assembly 41, as will be discussed below. It is
23 notable that the gears 55 are preferably a series of reduction
24 gears 55 which operate to reduce a fast rotational input provided
by the turbine drive shaft 51 to a relatively slower rotational
CA 02340285 2001-03-09




133/07
output at the final reduction gear 56 while increasing torque.
2 While it is understood and appreciated that various gear
3 reduction ratios may be employed, a typical and preferred
4 reduction ratio is 50 to 1.
As shown in the drawings, the roller assembly 41 is movably
secured to the rigid body 26 of the massager unit 25 wherefrom it
imparts an undulating perturbance through the massager openings
8 29 and 32. In particular, the roller assembly 41 preferably
9 includes a drive shaft 42 journaled to a pair of support columns
38 on the lower body portion 36 of the rigid body 26. The drive
11 shaft 42 preferably has an all-metal rigid construction, such as
12 steel, which is capable of supporting transverse loads thereon.
i3 With this arrangement, high spinning rotation of the turbine
14 drive 47 operates to rotate the steel drive shaft 42 and the
roller assembly 41. It is notable that typical turbine drive 47
16 speeds may range from approximately 1000-1500 RPM, with a drive
17 shaft output of approximately 20-30 RPM based on the exemplary
1s 50:1 reduction gearing. Moreover, typical pressures for spinning
19 the turbine drive 47 may range from 8-25 psi, depending on the
2o particular configuration.
21 Furthermore, as can be best seen in Figures 2, 3, and 4, the
22 roller assembly 41 has at least one disc-like central hub portion
23 43 fixedly secured to the drive shaft 42. The at least one hub
24 portion 43 has a plurality of nubs 45 arranged in a circular
2s manner along an outer perimeter 44 thereof. Preferably still,
1,
CA 02340285 2001-03-09




IJ.J/ O7
1 each nub is a roller 45 which is rotatably mounted on the outer
2 perimeter 44 of -the at least one hub portion 43. As can-be -seen
3 in Figures 3 and 4, a plurality of disc-like hub portions 43 are
4 preferably utilized and coaxially secured along the drive shaft
42. Moreover, multiple sets of roller nubs 45 are also
6 preferably utilized, with each set rotatably secured between
adjacently positioned disc-like central hubs 43. Each of the
s multiple sets of rollers 45 are preferably arranged to align each
g roller adjacent corresponding rollers of the multiple sets along
1o alignment axes parallel to the drive shaft 42. Furthermore, as
11 can be seen in Figure 4, each group of aligned rollers 45 are
12 preferably centrally mounted along a roller shaft 45' extending
13 through and supported by the outer perimeters 43 of each hub 43.
14 Arranged in this manner, Figure 2 illustrates the general
operation of the roller assembly 41, wherein each roller 45
16 partially protrudes through the at least one massager opening 29
1~ (and 32) in a cyclical manner as the hub 43 and drive shaft 42
18 are turned. This creates an undulating wave-like motion which
19 adds to the massaging effect. As can be seen in the drawings,
2o flexible diaphragms 30 and 33 are preferably utilized to cover
21 the two massager openings 29, 32 such that the rollers 45 may
22 rollably contact the inside surface of the diaphragms 30, 33 as
23 the hub 43 is rotated. It is appreciated, however, that the
24 roller assembly 41 may alternatively be utilized without the
2s diaphragms 30, 33, to contact a bather's feet directly. However,

2 portion 43 in a non-rotating manner, they may undesirably rub
3 against the soles of a bather's feet. In any case, rotation of
4 the roller assembly 41 functions to impart the undulating
s perturbance through the at least one massager opening 29, 32 when
6 the drive shaft 42 is rotated.
Now turning to the operation of the foot massaging system 10
s generally, Figures 5 and 6 show first and second preferred
operational arrangements of the foot massaging system 10. The
to massager unit 25 is positioned for use along the floor 13 of the
11 hydrotherapy hot tub 11 or other suitable horizontal underwater
12 surface thereof. Hydrodynamic power is provided to the massager
13 unit 25 by a fluid pump 15 having a pump inlet 16 and pump outlet
14 17, and powered by a pump motor 18. The fluid pump 15 and pump
1s motor 18 are preferably the system components of the hydrotherapy
15 hot tub construction, i.e. for pumping water through the water
i~ jet nozzles 21. However, they may alternatively be acquired from
18 a secondary source. In any case, the pump outlet 17 is suitably
19 connected to a plurality of jet nozzles 21 located along the tub
2o sidewall 14 of the hydrotherapy hot tub 11 by means of a pump
21 exit pipe 22. And the pump inlet 16 is connected to a body of
22 fluid, i.e. air or water, by means of a pump entry pipe 20. It
23 is notable that the body of fluid is preferably the water
24 contained in the hydrotherapy hot tub 11 as part of a re-
2s circulation system shown in Figures 5 and 6 utilizing a skimmer
1J

1 19. However, an air blowing system may alternatively be
2 utilized, wherein air is pumped to the jet nozzles 21 for an
3 effervescent bubble massage.
4 As can be seen in Figures 6 and 7, an inlet hose 23 is
s utilized for connecting the massager unit 25 to the pump 15.
Figure 5 shows a first preferred operational arrangement of the
7 massaging system 10, wherein the inlet hose 23 is routed through
s an access panel 12 into an interior space of the hydrotherapy tub
construction 11 to connect to the pump exit pipe 22. This
to provides parallel distribution of fluid flow to both the jet
11 nozzles 21 and the massager unit 25 separately. Alternatively, a
12 second preferred operational arrangement of the massaging system
13 10 is shown in Figure 6, where the inlet hose 23 connects
14 directly to a jet nozzle 21 along the tub sidewall 14. In either
15 case, the inlet hose 23 also connects to the turbine inlet port
15 49 of the turbine drive 47 through the inlet aperture 49 of the
17 rigid body 26. In this manner, fluid is pumped out from the pump
1s outlet 16 of the fluid pump 15 through the massager inlet hose
19 23, and into the turbine inlet port 49 to rotate the turbine
2o drive 47.
21 As shown in Figures 5 and 6, the fluid flow exiting from the
22 massager unit 25 may be expelled directly into the hydrotherapy
23 hot tub 11 (Figure 5), or alternatively conducted to the skimmer
24 area 19 (Figure 6) for re-circulation into the pump 15. The
25 skimmer 19 of the hydrotherapy tub 11 is of the type commonly

s used to filter as well as regulate the water level in the t"b 11,
2 and is connected to the pump inlet l~ via the pump entry pipe 20.
3 Where the turbine exhaust from the turbine outlet port 50 is
4 expelled directly into the tub 11, the turbine outlet port 50 and
the outlet aperture 40 (see Figure 3) are adaptively connected in
6 a direct manner (not shown). Where the exhaust is re-circulated,
however, an outlet hose 24 is provided with one end connected to
the turbine outlet port 50 of the turbine drive 47, and the other
9 end placed inside the skimmer 19 for connection to the pump inlet
16 of the pump 15. While not being bound by a particular theory
11 of operation, it is believed that this arrangement provides a
12 downstream suction which assists the fluid flow through the
13 turbine drive 47, for more efficient operation thereof. It is
14 notable in this configuration that the body of water or fluid
supplied to the pump inlet 16 of the pump 15 is not limited to
16 only the exhaust from the turbine outlet port 50. Rather, the
1? body of water entering the pump inlet from the skimmer is from
18 both the outlet hose 24, as well as the standing body of water in
19 the hydrotherapy hot tub 11.
2o In Figures 7 and 8 two preferred submersion methods are
21 shown for maintaining the massager unit 25 against an underwater
22 surface, e.g. the floor 13, in the hydrotherapy hot tub 11. Due
23 to the typically polycarbonate or other plastic material
24 construction of the rigid body 26, the massager unit 25 has a
buoyant tendency characteristic of materials having a density

2 best in Ffigure 3, sufficiently heavy weights 6l may be secured to
3 the rigid body 26 to overcome the buoyancy and cause the massager
4 unit 25 to sink. As can be seen in Figure 3, this weighty
s element 61 may be aligned along the lower panels of the lower
6 body 36.
Alternatively, as shown in Figures 7 and 8, a skirt 57 may
s be provided for surrounding an underside of the rigid body 26.
g The skirt operates as a barrier wall for containing a low-
Zo pressure, evacuated volume and thereby sustaining a suction
11 force. To this end, the skirt 57 is preferably fabricated from a
12 flexible elastomeric material. Additionally, a pump means for
13 evacuating water from the underside of the rigid body 26 is
14 provided, such that the massager unit 25 may be suctioned against
15 the floor surface 13 of the hydrotherapy hot tub 11. This if
16 preferably the fluid pump 15 of the hydrotherapy hot tub 11, or
1~ may alternatively be a secondary pump. In any case, as can be
1s seen in Figures 7 and 8, the outlet hose 24 which connects to the
19 pump inlet 16 via the skimmer 19 may be connected to the
2o underside of the rigid body 26 to create a suction 58. For
21 illustrative purposes, the underside of the rigid body 26 is
22 shown in Figures 7 and 8 to be the interior space of the massager
23 unit 25 below the upper body portion 27, and in direct
24 communication with the floor surface 13.

2 evacuating pump means where the exhaust flowing out from the
3 turbine outlet port 50 is jettisoned out into the water medium of
4 the tub 11. In this arrangement, the outlet hose 24 may be
connected to the rigid body 26 directly at a suction port 59 such
that a suction force 58 may be produced which does not assist in
the fluid exhaust exiting the turbine outlet port 50. In
s contrast, as can be seen in Figure 8, a second configuration is
shown where the outlet hose 24, which is a vacuum hose, may be
so connected directly to the turbine outlet port 50 with a secondary
m vacuum valve 60 opening into the underside of the rigid body 26.
12 This arrangement provides a parallel suction force 58 to the
s3 turbine drive 47 and the underside of the rigid body 26.
14 Consequently, this arrangement provides downstream assistance for
rotating the turbine drive, as well as maintaining the massager
15 unit 25 against the floor surface 13.
1'7 The term "undulating perturbance" is defined herein and in
1s the claims to mean any variety of massaging physical agitation or
19 motion exerted by the massager means which applies a massaging
2o force in a wave-like manner with reciprocating high and low
21 magnitudes.
22 The present embodiments of this invention are thus to be
23 considered in all respects as illustrative and not restrictive;
24 the scope of the invention being indicated by the appended claims
rather than by the foregoing description. All changes which come
