  • both the first and second pins 102 and 105 of the first and second leaf springs 100 and 104 are located between the first and second step portions 95 and 96 of the first and second guide grooves 93 and 94 with respect to the radial direction of the rotating disk 91, the first pin 102 of the first leaf spring 100 will first run onto the first step portion 95 of the first guide groove 93, as indicated by the imaginary line in Fig. 15, as the rocking arm 97 rocks in the direction of arrow D1 in Fig. 13.
  • the first leaf spring 100 of the rocking arm 97 bends backward, as indicated by the imaginary line in Fig. 16, to press the push button 108 of the first limit switch 107, thereby shifting the switch 107.
  • the rotation of the output shaft 43 of the unit motor 42 is reversed from the direction of arrow Al to the direction of arrow A2 by the aforementioned electric circuit, so that the traveling belts 36, having so far been running in the direction of arrow Bl through the upper passages 19 of the guide rails 14, start to run in the direction of arrow B2 opposite to the direction of arrow B1.
  • the rotating direction of the output shaft 43 of the unit motor 42 is switched from the direction of arrow Al to the direction of arrow A2
  • the rotating direction of the rotating disk 91 is changed from the direction of arrow C1 to the direction of arrow C2.
  • the rocking direction of the rocking arm 97 is changed from the direction of arrow D1 to the direction of arrow D2.
  • the traveling belts 36 running through the upper passages 19 of the guide rails 14 automatically change their courses from the direction of arrow Bl to the direction of arrow B2 or from B2 to Bl. Accordingly, the carriers 60 coupled to the traveling belts 36 and hence the first and second massage rollers 76 and 80 are reciprocated along the guide rails 14.
  • the reciprocation stroke of the carriers 60 or the massage rollers 76 and 80 depends on the radial distance of the rotating disk 91 between the first step portion 95 of the first guide groove 94 and the second step portion 96 of the second guide groove 94.
  • control unit 90 serves to determine the maximum reciprocation stroke of the carriers 60, part within the maximum reciprocation stroke of the carriers 60 may be restricted by the electric circuit.

  • the remote switch (not shown) to actuate the unit motor 42
  • the massage rollers 76 and 80 will reciprocate along the guide rails 14 while rotating in contact with the inside of the warpping cloth 13.
  • the back of the user is massaged by the massage bumps 77 of the massage rollers 76 and 80.
  • the massage apparatus with this construction can be folded in two as shown in Fig. 18, since the central portions of the base plate 1 and the guide rials 14.are expressly flexible.
  • Fig. 19 shows a cross-sectional view of a fold portion of the massage apparatus.
  • each guide rail 14 is fixed to the base plate 1 by means of the fixing screws 21, while the other end side of each guide rail 14 is slidably held over the base plate 1 by means of the support members 22. Accordingly, the guide rails 14 or the whole massage apparatus can be easily be folded without producing any substantial bending stress in the guide rails 14.
  • the traveling belts 36 are used as elongated members for power transmission.
  • the blets 36 may be replaced with chains or wires.
  • the predetermined folding portion of the base plate 1 is formed by coupling a plurality of belt-shaped plate members 120 by means of hinges 121.
  • the predetermined folding portion of the base plate 1 consists of a corrugated coupling member 122 made of an elastic material such as synthetic resin. Each end of the coupling member 122 is fixed to the end portion of each corresponding division of the base plate 1 by means of a fitting piece 123.
  • the slits 33 are arranged at regular intervals throughout the length of the guide rail 14.
  • the guide rail 14 is formed of a flexible material such as polypropylene or rubber, and can be folded without the slits 33.
  • the slits 3 are arranged at regular intervals throughout the length of the base plate 1.
  • Fig. 25 shows a combination of the guide rail 14 of Fig. 22 and the base plate 1 of Fig. 24, while Fig. 26 shows a combination of the base plate 1 of Fig. 24 and the guide rail 14 of Fig. 23.
  • Figs. 27 to 29 show modifications in which the base plate 1 is formed of a flexible material such as polypropylene or rubber, and can be folded without the slits 3.
  • Fig. 27 shows a combination of the base plate 1 with this arrangement and the guide rail 14 of Fig. 19
  • Fig. 28 shows a combination of the base plate 1 and the guide rail 14 of Fig. 22
  • Fig. 29 shows a combination of the base plate 1 and the guide rail 14 of Fig. 23.
  • the above description is premised on an assumption that the massage apparatus is folded in two.
  • the whole massage apparatus may be folded in the manner shown in Fig. 30 or 31 by providing each of the base plate 1 and the guide rail 14 with two or more predetermined fold portions or by making the base plate 1 and the guide rail 14 foldable at any position in the aforementioned manner.
  • a base to be used in place of the base plate 1 includes two flexible or rigid plates 130 arranged so as to support the whole length of each guide rail 14 except the central portion thereof, and a plurality of auxiliary crosspieces 131 arranged at regular intervals along the guide rails 14 between the plates 130.
  • the massage apparatus may be folded in the manner shown in Fig. 34 or 35, for example.
  • Fig. 36 shows a modification in which the base is formed of the two plates 130 only
  • Fig. 37 shows an example in which the base includes three plates 130 and the auxiliary cross-piece 131 arranged between the plates 130.
  • Fig. 39 shows a base which is formed of two plates 132 at both ends of each guide rail 14 and two auxiliary crosspieces 131 arranged between the plates 132. With the use of the bases shown in Figs. 37 to 39, the base can be folded at a plurality of positions.
  • Figs. 40 and 41 show a base which comprises two rigid plates 130 and a flexible plate 200 disposed between the plates 130, the flexible plate 20 made of polypropylen, for example.
  • the base may be provided as required, and is not an essential member.
  • a first modification of the carriers 60 With a carrier 60' according to the first modification, the support leg 62 and the traveling belt 36 are not coupled directly by the coupler 70, and a wire 140 is used in aid of the coupler 70.
  • the wire 140 is slidably passed through a pipe portion 141 which is formed by bending the lower end portion of the coupler 70.
  • Each end side of the wire 140 passed through the pipe portion 141 of the coupler 70 extends through the upper passage 19 of the guide rail 14, passes through a pair of pipes 143 fixed to the traveling belt 36 by means of a mounting plate 142, as shown in Fig. 45, and is then bent upward.
  • Both ends of the wire 140 are attached to a mounting plate 145 on the support leg 62 with the aid of metal fittings 146 and a screw.
  • the wire 140 forms a triangle with its base extending along the guide rail 14, as shown in Fig. 42.
  • the wheels 67 are attached to the support leg 62 so as to project outward from the support leg 62, as shown in Fig. 42.
  • the massage apparatus can easily be folded even at the position where the carrier 60' is located. If the massage apparatus is folded at the location of the carrier 60', the base of the substantially triangular wire 140 is bent as shown in Fig. 46. As the wire 140 is bent in this manner, the carrier 60' is moved in the direction of arrow F in Fig. 46, so that the massage apparatus can easily be folded without being substantially hindered by the carrier 60'. If the distance between the pair of pipes 143 before the holding of the massage apparatus is w2, as shown in Fig.
  • the distance wl between the pipes 143 after the folding is shorter than the distance w2 by a length for the flexure of the base of the wire 140.
  • a second modification of the carrier 60 In a carrier 60" according to the second modification, the support leg 62 is provided with a pair of first links 150 which are rockably mounted at the upper end portion thereof on each hollow shaft 61. The lower end portions of the first links 150 spread away from each other, and are rotatably fitted with the wheels 67 by means of the support shafts 68.
  • One end of each of a pair of second links 151 is rockably coupled to the support shaft 68 of each corresponding wheel 67.
  • the other ends of the second links 151 are rockably coupled to a first coupler 152 by means of a pin 153.
  • the first coupler 152 is fixed to the traveling belt 36 guided through the upper passage 19 of the guide rail 14.
  • Second couplers 154 are attached to the support shafts 68 of their corresponding wheels 67.
  • the support shafts 68 of the wheels 67 are passed through guide holes 155 in their corresponding second couplers 154, and the second couplers 154 are fixed to the traveling belt 36 in the guide rail 14 in the same manner as the first coupler 152.
  • the carrier 60" of the second modification can provide the same function and effect as those of the carrier 60' of the first modification.
