Referring now to the drawings~ in one embodiment a massaging device 10 comprises a power head 11 having a variable speed electric motor and gear box with a speed control knob 12 for varying speed of the unit.
The power head 13 may be attached to the ceiling either by a rail so that it moves from one side of the room to another, or alternatively, may be on a swinging arm attached eithe~ to the wall or to a stand. In this manner, the power head 11 is placed high up in a room generally above a table, bed or the like~ where a person is receiving treatment.
The power head 11 has a connection 14 to a flexible extension shaft 15. The shaft 15 connects to a custom molded receptacle handle 16. A first replaceable massage head 17 is shown in FIG 1 mourlted to the receptacle handle 16 and a second replaceable massage head 18 is shown in FIG 2. Whereas two types of replaceable heads 17 and 18 are shown, it will be apparent that other types of heads may be supplied for attachment to the receptacle handle 16.
Details of the receptacle handle 16 are shown in FIG 3, the handle portion 20 is hollow having a shaft 21 extending down -the center and ending in a connecting drive plug 22 with straight sides and a spring held ball for snap connection to a ~ocket. The receptacle handle 16 has a hollow cylindrical end portion 24 with an engagement pin 25 for engagement with the sec~nd replaceable massage head 18. When the massage head 17 or 18 is snapped into the hollow cylindrical end portion 24 of the receptacle handle 16, khe end of the massage head is flush with the cylindrical end portion 24 as illustrated in FIG 1.
The first replaceable massage head 17 is shown in FIG 4 and described as the deep muscular petrissage head. A cylindrical disc 30 fits into the cylindrical end portion 24 of the receptacle handle 16. A drive socket 31 extends inwards from the disc 30 and is rigidly attached to the cylindrical disc 30. The drive socket 31 fits over the connecting plug 22 having a detent to engage the spring held ball to provide a positive connection so that when the shaEt 21 in the handle 16 rotates, the circular disc 30 also rotates.
There is a space left free for the disc 30 to rotate and not engage the engagement pin 25 in the end portion 24. A guide ring 34 is provided at the base of the drive socket housing 31 to rub on the inside surface of the hollow end portion 24 of the handle 16. On the surface of the cylindrical disc 30 six substantially similar protruding cylindrical Eingers 32 with semi-spherical ends are positioned equidistant apart in a circle about the axis of rotation oE the cylindrical disc 30. The protruding fingers 32 are made of resilient material such as rubber and in one embodiment are an inch in diameter extending for two inches Erom the surface oE the disc 30. In the center of the 131 1 16~
disc 30~ protruding out~ards, is a center finger 33 which is substantially square and also made of resilient ma-terial. Whereas the center finger 33 is shown as being square, it may be triangular or rectangular, provided it has flat sides. In the embodiment illustrated, the center finger 33 is the same length as the cylindrical fingers 32, but may be either slightly longer or shorter. The purpose of the flat surface on the center finger 33 is to provide a pinching action to the muscles between the cylindrical fingers 32 and the flat surface of the center finger 33. Whereas six cylindrical fingers 32 are illustrated, this number may be more or less depending upon the massage re~uirements.
The second replaceable massage head 18 is shown in FIG 5 and has a cylindrical disc 4, which fits into the cylindrical end portion 24 of the handle 16. An engagement aperture 42 is provided to line up and engage the engagement pin 25 in the end portion 24 in the handle 16 so that when the replaceable head 18 is fitted to the handle 16, the cylindrical disc 40 cannot rotate, and is locked -to the handle. A drive socket 43 is mounted on a shaft 44 and positioned in the center interior of the circular disc 40 ~or connection to the connecting plug 22 in the end portion 24 of the handle 16. The shaft 44 is mounted on bearings 45 so that it rotates within the circular disc 40 and has a pinnion gear 46 engaging two separately mounted bevel gears 47 on each side o the center axis each having an axis of rotation tilting inwards. The separately mounted bevel gears 47 are each connected to an eccentric pin 48 which extends through a bearing 49 to protrude from the surface of the circular disc 40.
Each eccentric pin 48 is located within a cylindrical ~6- 131 1 1~8 Einger 50 attached to the surface of the circular disc 40 such that when the eccentric pin 48 rotates, the tip 51 of the finger 50 rotates in a circle whereas the base of thr- finger is stationary. In the embodiment shown, the finger 50 is a sheath with the eccentric pin ~8 rotating within the sheath so that the surface of the sheath does not rota-te, but the tip 50 is deformed in a circular motion. As can be seen in FIG 5, the drive mechanism is similar to that of an egg beater, the eccentric pins 48 are counter rotating and when used as a massage provide deep circular friction.
In one embodiment the fingers are one half in diameter and spaced about one inch apart at the disc portion. The two fingers 50 tilt inwards, so the distance between the fingers at the tips 51 is about three quarters of an inch without takin~ into account the eccentricity. The tips 51 have an eccentric rotation of approximately one quarter inch diameter.
In both cases, the speed of the device may be varied by the speed control knob 12 on the power head 11. In the case of the second replaceable massage head 17, the fingers 50 are formed of resilient material to allow the eccentric pin 48 to rotate within.
The materials of construction are preferably aluminum or hard plastic for the circular discs 30 and 40 of both replaceable massage heads 17 and 18.
Various changes may be made to the embodiments shown herein without departing from the scope of the present invention which is limited only by the following claims.

Whereas two types of replaceable heads 17 and 18 are shown, it will be apparent that other types of heads may be supplied for attachment to the receptacle handle 16.
Details of the receptacle handle 16 are shown in FIG 3, the handle portion 20 is hollow having a shaft 21 extending down -the center and ending in a connecting drive plug 22 with straight sides and a spring held ball for snap connection to a ~ocket. The receptacle handle 16 has a hollow cylindrical end portion 24 with an engagement pin 25 for engagement with the sec~nd replaceable massage head 18.

Whereas six cylindrical fingers 32 are illustrated, this number may be more or less depending upon the massage re~uirements.
The second replaceable massage head 18 is shown in FIG 5 and has a cylindrical disc 4, which fits into the cylindrical end portion 24 of the handle 16. An engagement aperture 42 is provided to line up and engage the engagement pin 25 in the end portion 24 in the handle 16 so that when the replaceable head 18 is fitted to the handle 16, the cylindrical disc 40 cannot rotate, and is locked -to the handle. A drive socket 43 is mounted on a shaft 44 and positioned in the center interior of the circular disc 40 ~or connection to the connecting plug 22 in the end portion 24 of the handle 16. The shaft 44 is mounted on bearings 45 so that it rotates within the circular disc 40 and has a pinnion gear 46 engaging two separately mounted bevel gears 47 on each side o the center axis each having an axis of rotation tilting inwards. The separately mounted bevel gears 47 are each connected to an eccentric pin 48 which extends through a bearing 49 to protrude from the surface of the circular disc 40.
