14 A neck massager for spas is shown in perspective view in Figure 1 and indicated generally by reference character 10. The 16 neck massager of Figure 1 is designed to be mounted in the 17 sidewall of a spa 11 in a waterproof manner. It is preferably 18 mounted at an angle of about 45~ to the horizontal. The massager 19 has a pair of knobs 12 and 13 below a flexible diaphragm 14. The inner workings are shown best in Figures 2 and 3 where it can be 21 seen that knob 12 is held on a shaft 15 which is turned by a bent 22 fitting 17 affixed to shaft 16. The bent fitting 17 causes the 23 tip 18 of knob 12 to be offset a distance 19 from the axis of 24 rotation 20 of massage arm shaft 16. Distance should be between - CA 02231309 1998-03-0~
about 0.5" and 2.0" and preferably about 1.0". Bent fitting 17 2 is preferably at an angle of about 30~.
3 An electric motor 21 is held within housing 22 as are a 4 series of gears 23. Motor 21 has a driven shaft 24 to which an output gear 25 is held. Output gear 25 drives gear 26 which has 6 a smaller gear 27 around the shaft 28' thereof. Smaller gear 27 7 drives gear 28 which also has a smaller gear 29 in its center.
8 Smaller gear 29 in turn drives gear 30 which is attached to shaft 9 16.
The gear train is shown best in Figure 4 of the drawings 11 where it can be seen that gear 30 drives a pair of idler gears 31 12 and 32 which in turn drive gear 33 in the opposite direction from 13 gear 30. With a 1500 RPM motor the massage gears 30 and 33 14 rotate at a speed of about 30 RPM which provides a slow and pleasant massage action by the movement of knobs 12 and 13 under 16 diaphragm 14.
17 Diaphragm 14 is fabricated from a flexible material 18 preferably an elastomer such as polyurethane. The diaphragm 14 19 is preferably waterproof as is the gear box 34 portion of housing 22. Housing 22 is covered by a weatherproof cover 38. An O-ring 21 seal 35 preferably is held by a series of bolts and nuts to the 22 spa shell 11.
23 The unit is shown in Figure 3 without gears where the 24 support for shafts 16 and 16' can be seen to be held in shaft cups 39 and 39'. The other gears are similarly supported.

1 The wall mounted massager of the present invention is 2 preferably mounted in a flattened portion of a spa fabricated 3 especially for the use of such massager, although other mounting 4 methods can be used to adapt existing spas to the use of the massager of the present invention. The knobs preferably each 6 have a rounded hemi- spherical ends having a diameter of about 7 1.5". The knobs are preferably fabricated from a polymer having 8 a lligh degree of surface slip and abrasion resistance such as 9 nylon, and with the knobs operating in opposite directions, the massaging action is especially effective.
11 A cable driven version of the massager of the present 12 invention is shown in Figure 8 and indicated by reference 13 character 40. Two massage units are shown in the spa 41 and 14 these may be hand held or attached to a spa wall by suction cups or other means. The massage unit is identical to that shown in 16 Figures 1 through 7 except that in place of motor 21 a drive 17 cable 42 is utilized. Drive cable 42 is flexible and, as shown 18 in Figure 10 has a stationary outer sleeve or conduit 43 and a 19 rotating inner driven cable 44. Such cables are used in a smaller version as speedometer cables and in larger versions to 21 remotely drive a tool. Inner cable 44 would be attached to 22 driven shaft 24 so that it is driven by inner cable 44 in place 23 of motor 21. Inner cable 44, in turn, is driven by motor 45.
24 Motor 45 is shown attached to an outer portion of spa 41 and is provided with means to protect the motor from the elements and to CA 0223l309 l998-03-0~
1 prevent the motor from being touched by users of the spa. The 2 use of a cable driven massager permits the user to position the 3 massager 40 in any preferred location.
4 One of the advantages of providing a waterproof diaphragm and body is that the massager 40 can be operated under the 6 surface 54 of the water in the spa. Both the hollow flexible 7 conduit 4 3 and the body of the massager are waterproof as is the 8 diaphragm. Thus, the massager 40 of Figure 8 can be positioned 9 at any desirable position.
A different version of a hand held massager is shown in 11 Figure 10 and indicated by reference character 46. Massager 46 12 is also like massager 40 except that it is driven by a water 13 turbine which turns driven shaft 24. Water is fed through hose 14 47 into massager 46 which contains a conventional turbine, not shown. Water is supplied from within spa 48 through conduit 49.
16 Conduit 4g is affixed to the inlet of pump 50 which is driven by 17 motor 51. Pump 50 feeds water at a high pressure to conduit 52 18 which, in turn, is attached to flexible hose 47. The water from 19 the massager turbine simply drains back into the spa as indicated at reference character 53.
21 A spa wall-mounted massager 55 is shown in Figure 11 and 22 this massager is driven by the hollow flexible cable 42 of Figure 23 9. The motor 45 is positioned behind spa wall 56 and at a level 24 below spa seat 57 and above the bottom 58 of spa 41. In this CA 02231309 1998-03-0~
1 way, motor 45 is protected from any contact by the user. It is 2 shown in Figure 11 attached to the outer wall 60 of the spa.
3 The massager body or housing 22 is shown mounted in a manner 4 similar to that shown in Figure 1 and the diaphragm 14 is held about diaphragm opening 61 in a waterproof manner similar to that 6 shown in Figure 1. At least two massage arms 62 and 63 are shown 7 in Figure 11 and they may be of any construction as long as they 8 provide an undulating motion to waterproof diaphragm 14.
9 A water driven massager is shown in ~igure 12 and the massager body 22 is the same as that shown in Figure 10. A pump 11 motor 64 drives a high pressure water pump 65 which provides high 12 pressure water to the jets of the spa (not shown) through pipe 13 66. On/off valves 67 and 68 control the flow of water to the 14 jets and the massager respectively. A conduit 69 feeds water to a tur~ine not shown, but of conventional construction which turns 16 the massager arms in a manner similar to that described above. A
17 water outlet conduit 70 is attached to the outlet of the turbine 18 not shown and is connected to an inlet line 71 of pump 65.
19 An alternate embodiment of a massager unit is shown in Figures 13, 14 and 15 of the drawings. The massager body 21 supports a massager wheel support shaft 72 to which massage 22 wheels 73, 74, 75 and 76 are rigidly mounted. Wheels 73, 74, 75 23 and 76 support six rollers 77 rotatingly mounted on axles 78.
24 Massage wheel support shaft 72 is driven by a belt not shown.
CA 0223l309 l998-03-0~
1 Rollers 77 cause the flexible diaphragm 14 to undulate and 2 provide a massaging action against the user's neck.
3 Thus, a neck and upper massager may be held either by a spa 4 wall or against a spa wall and is provided with a waterproof housing and diaphragm so that it may be used in a spa 6 environment. The portable version may be moved to any 7 comfortable position either above the water level or below it and 8 the motor which drives the massager is safely held out of the way 9 below the spa wall.
The present embodiments of this invention are thus to be 11 considered in all respects as illustrative and not restrictive;
12 the scope of the invention being indicated by the appended claims 13 rather than by the foregoing description. All changes which come 14 within the meaning and range of equivalency of the claims are intended to be embraced therein.
7 The field of the invention is muscle massagers and the 8 invention relates more particularly to neck and shoulder 9 massagers of the type which tend to be used with spas, hot tubs or whirlpool baths.
11 A hydro-massage unit for a spa is shown in U.S. Patent No.
12 4,839,930. This device provides a flow of water against the 13 inner surface of a diaphragm which provides a massage for a 14 user's neck. A waterproof vibrating cushion is shown in U.S.
Patent No. 4,935, 972. It is waterproof and may be used in a spa 16 or a bath tub. It utilizes a vibrator element within a cushion.
17 While both of these devices provide a degree of neck and 18 shoulder massage, neither is positioned in a spot to utilize the 19 comfortable shape of the spa.

6 The present invention is for a neck and upper shoulder 7 massager for mounting in a spa, whirlpool bath or the like. The 8 neck and upper shoulder massager is held in a housing which may 9 be held in or against the sidewall of a spa. The massager has a massager body held in an opening in the sidewall or against the 11 opening in the sidewall of the spa in a waterproof manner so that 12 no water may be passed into the massager body. A waterproof 13 massager diaphragm is held in a watertight manner over a 14 diaphragm opening in the massager body. At least two massagers are held in a moveable manner by the massager body. Each 16 massager has a massager face which contacts an underside of the 17 waterproof massager diaphragm and each of the massagers is 18 supported so that they are capable of moving in an undulating 19 manner under the waterproof massager diaphragm. The massagers may be turned either by a motor held within the massager body, a 21 motor which drives a driven cable within a hollow conduit 22 attached to a remote motor and to the massager body or by water 23 power driving a turbine held within the massager body. The 24 massagers may be rotating angled arms or rotating angled massage wheels or cams.

14 A neck massager for spas is shown in perspective view in Figure 1 and indicated generally by reference character 10. The 16 neck massager of Figure 1 is designed to be mounted in the 17 sidewall of a spa 11 in a waterproof manner. It is preferably 18 mounted at an angle of about 45~ to the horizontal. The massager 19 has a pair of knobs 12 and 13 below a flexible diaphragm 14. The inner workings are shown best in Figures 2 and 3 where it can be 21 seen that knob 12 is held on a shaft 15 which is turned by a bent 22 fitting 17 affixed to shaft 16. The bent fitting 17 causes the 23 tip 18 of knob 12 to be offset a distance 19 from the axis of 24 rotation 20 of massage arm shaft 16. Distance should be between - CA 02231309 1998-03-0~
about 0.5" and 2.0" and preferably about 1.0". Bent fitting 17 2 is preferably at an angle of about 30~.
3 An electric motor 21 is held within housing 22 as are a 4 series of gears 23. Motor 21 has a driven shaft 24 to which an output gear 25 is held. Output gear 25 drives gear 26 which has 6 a smaller gear 27 around the shaft 28' thereof. Smaller gear 27 7 drives gear 28 which also has a smaller gear 29 in its center.
8 Smaller gear 29 in turn drives gear 30 which is attached to shaft 9 16.
The gear train is shown best in Figure 4 of the drawings 11 where it can be seen that gear 30 drives a pair of idler gears 31 12 and 32 which in turn drive gear 33 in the opposite direction from 13 gear 30. With a 1500 RPM motor the massage gears 30 and 33 14 rotate at a speed of about 30 RPM which provides a slow and pleasant massage action by the movement of knobs 12 and 13 under 16 diaphragm 14.
17 Diaphragm 14 is fabricated from a flexible material 18 preferably an elastomer such as polyurethane. The diaphragm 14 19 is preferably waterproof as is the gear box 34 portion of housing 22. Housing 22 is covered by a weatherproof cover 38. An O-ring 21 seal 35 preferably is held by a series of bolts and nuts to the 22 spa shell 11.
23 The unit is shown in Figure 3 without gears where the 24 support for shafts 16 and 16' can be seen to be held in shaft cups 39 and 39'. The other gears are similarly supported.

1 The wall mounted massager of the present invention is 2 preferably mounted in a flattened portion of a spa fabricated 3 especially for the use of such massager, although other mounting 4 methods can be used to adapt existing spas to the use of the massager of the present invention. The knobs preferably each 6 have a rounded hemi- spherical ends having a diameter of about 7 1.5". The knobs are preferably fabricated from a polymer having 8 a lligh degree of surface slip and abrasion resistance such as 9 nylon, and with the knobs operating in opposite directions, the massaging action is especially effective.
11 A cable driven version of the massager of the present 12 invention is shown in Figure 8 and indicated by reference 13 character 40. Two massage units are shown in the spa 41 and 14 these may be hand held or attached to a spa wall by suction cups or other means. The massage unit is identical to that shown in 16 Figures 1 through 7 except that in place of motor 21 a drive 17 cable 42 is utilized. Drive cable 42 is flexible and, as shown 18 in Figure 10 has a stationary outer sleeve or conduit 43 and a 19 rotating inner driven cable 44. Such cables are used in a smaller version as speedometer cables and in larger versions to 21 remotely drive a tool. Inner cable 44 would be attached to 22 driven shaft 24 so that it is driven by inner cable 44 in place 23 of motor 21. Inner cable 44, in turn, is driven by motor 45.
24 Motor 45 is shown attached to an outer portion of spa 41 and is provided with means to protect the motor from the elements and to CA 0223l309 l998-03-0~
1 prevent the motor from being touched by users of the spa. The 2 use of a cable driven massager permits the user to position the 3 massager 40 in any preferred location.
4 One of the advantages of providing a waterproof diaphragm and body is that the massager 40 can be operated under the 6 surface 54 of the water in the spa. Both the hollow flexible 7 conduit 4 3 and the body of the massager are waterproof as is the 8 diaphragm. Thus, the massager 40 of Figure 8 can be positioned 9 at any desirable position.
A different version of a hand held massager is shown in 11 Figure 10 and indicated by reference character 46. Massager 46 12 is also like massager 40 except that it is driven by a water 13 turbine which turns driven shaft 24. Water is fed through hose 14 47 into massager 46 which contains a conventional turbine, not shown. Water is supplied from within spa 48 through conduit 49.
16 Conduit 4g is affixed to the inlet of pump 50 which is driven by 17 motor 51. Pump 50 feeds water at a high pressure to conduit 52 18 which, in turn, is attached to flexible hose 47. The water from 19 the massager turbine simply drains back into the spa as indicated at reference character 53.
21 A spa wall-mounted massager 55 is shown in Figure 11 and 22 this massager is driven by the hollow flexible cable 42 of Figure 23 9. The motor 45 is positioned behind spa wall 56 and at a level 24 below spa seat 57 and above the bottom 58 of spa 41. In this CA 02231309 1998-03-0~
1 way, motor 45 is protected from any contact by the user. It is 2 shown in Figure 11 attached to the outer wall 60 of the spa.
3 The massager body or housing 22 is shown mounted in a manner 4 similar to that shown in Figure 1 and the diaphragm 14 is held about diaphragm opening 61 in a waterproof manner similar to that 6 shown in Figure 1. At least two massage arms 62 and 63 are shown 7 in Figure 11 and they may be of any construction as long as they 8 provide an undulating motion to waterproof diaphragm 14.
9 A water driven massager is shown in ~igure 12 and the massager body 22 is the same as that shown in Figure 10. A pump 11 motor 64 drives a high pressure water pump 65 which provides high 12 pressure water to the jets of the spa (not shown) through pipe 13 66. On/off valves 67 and 68 control the flow of water to the 14 jets and the massager respectively. A conduit 69 feeds water to a tur~ine not shown, but of conventional construction which turns 16 the massager arms in a manner similar to that described above. A
17 water outlet conduit 70 is attached to the outlet of the turbine 18 not shown and is connected to an inlet line 71 of pump 65.
19 An alternate embodiment of a massager unit is shown in Figures 13, 14 and 15 of the drawings. The massager body 21 supports a massager wheel support shaft 72 to which massage 22 wheels 73, 74, 75 and 76 are rigidly mounted. Wheels 73, 74, 75 23 and 76 support six rollers 77 rotatingly mounted on axles 78.
24 Massage wheel support shaft 72 is driven by a belt not shown.
CA 0223l309 l998-03-0~
1 Rollers 77 cause the flexible diaphragm 14 to undulate and 2 provide a massaging action against the user's neck.
3 Thus, a neck and upper massager may be held either by a spa 4 wall or against a spa wall and is provided with a waterproof housing and diaphragm so that it may be used in a spa 6 environment. The portable version may be moved to any 7 comfortable position either above the water level or below it and 8 the motor which drives the massager is safely held out of the way 9 below the spa wall.
The present embodiments of this invention are thus to be 11 considered in all respects as illustrative and not restrictive;
12 the scope of the invention being indicated by the appended claims 13 rather than by the foregoing description. All changes which come 14 within the meaning and range of equivalency of the claims are intended to be embraced therein.
