Background Art The applicant of this invention formerly proposed a magnetic therapeutic apparatus formed by flexibly 0 connecting in one row, a plurality of cases each housing solenoids therein, with their magnetic pole faces orienting in the same direction. After this magnetic therapeutic apparatus is installed by winding it around a r" diseased part of a human body, when A.C current is flowed through the solenoids of each case, an alternating magnetic field generated from each solenoid acts on the human body, thereby alleviating from various symptoms I such as stiffness. Furthermore, this magnetic therapeutic apparatus generates vibration and heat due to current conduction to the solenoids, thereby providing the human body with a massaging effect, as well as a W t i I I 219/ A. Ic -2warming effect.

A magnetic therapeutic apparatus of this type has a structure in which cases containing solenoids are connected in one row, thus even when the apparatus is installed by winding it around the human body, an effective range of the magnetic fields is limited to a narrow scope.

ce t In one preferred mode, the whole of said bed is formed integrally by a fiber reinforced plastic (called FR'P), and a plural number of air holes are formed in said support face. Furthermore, a cooling fan may be installed inside the bed with a direction of air flow facing the support face.

As regards the covers, either of them is formed into a curved shape, the lateral center portion is high and both side ends are low, on the basis of the support face of the bed, in one aspect. And in other aspect, it is pivoted at one side end to a side end portion of said bed, and in another aspect, it is hanged on said bed by a support arm connected inclinably to the bed and by a support frame connected pivotally to the support arm.

And air holes 6 are designed to As shown in Fig. 3, said support face 2 of the bed 1 is consisceleratein of air head supporting portion 2A, aetic back support portion 2B and a leg support portion 2C, a ong which the back support portion 2B is, ,s shown in Fig. 6, ormed ratinto a curved surfato be whos e lateral cen ter portio is low and both sides a re high, and provided cooith a largect nurther air holesing fan 14 is instaloles 6 arinside thdesigned to "with i ts direction ofhe air flow for directling toward the backield support portion 2B of the support face 2. The air holes 6 are formed not only in the back support portion 2B13, but also in the head support portion 2A and the leg support portion 2C. In Fig. 3 and Fig. 6, a reference character 2D designates arm support portions formed on both sides of the back support portion 2B.

On the head support portion 2A, back support portion 2B, leg support portion 2C and arm support portion 2D of the support face 2, a suitable number of magnetic field generating units 10 each of which is constituted by connecting five magnetic field generators 15 in a row are disposed respectively, so as to apply magnetic fields generated by the magnetic field generating units 10 to the entire body.

As shown in Fig. 7 and Fig. 8, each magnetic field generator 15 is constituted by disposing electromagnetic solenoids 17 in case 16 made of synthetic resin. Each of the cases 16 is formed by facing the open end faces of a pair of partial cases 16a, 16b and fixing a plural positions by screws 16c. On side end faces of each case either protruded axes 18a, 18a or bearing hols 18b, 18b are formed, thereby the adjacent cases 16, 16 are pivotally connected with each other by engaging protruded axes 18a into the respective bearing holes 18b.

S, As shown in Fig. 9, said electromagnetic solenoid 17 is consisting of a Laminated iron core 20 including divided portions 22, 23 at opposite ends of a base S 20 portion 21, and coil bobbins 31, 32 engaged to the divided portions 22, 23. The coil bobbins 31, 32 are constructed by winding coils 37, 38 around spools 35, 36 which is made of synthetic resin and have collars 33, 34 at opposite ends respectively. When an AC current is 6 0 41 hll 44h4 20 t 4 -7 applied to tile coils 37, 38, an alternating magnetic fields are generated from the ends of the divided portions 22, 23.

The electromagnetic solenoid 17 is fixed inside the case 16. with the ends of the divided portions 22, 23 facing one partial case 16a, thereby an external face of the partial case 16a serves as a magnetic-pole face 11 generating the magnetic field.

In addition, on the magnetic-pole face 11 of the partial case 16a, a radiation coating -film 19 may be formed, as required, by coating the face with a far infrared radiating material such as zirconia, zircon, titania, alumina, cordierite, quartzite and so on. The above far infrared radiating materials radiate the far infrared rays when excited by heating. Besides coating the surface of the case 16 with the far infrared radiating materials, they may be mixed into the molding materials of the case 16.

The magnetic field generating units 10 are disposed on the support face 2 with their magnetic-pole faces I.

Also on each side on the leg support portion 2C, one set of magnetic field generating unit 10 is disposed with its magnetic-pole faces 11 facing upward. Furthermore, at the left and right end positions of the leg support portion 2C, a pair o-f support plates 8 are disposed lengthwise on both sides of the bed 1, and one 0 9.

The head cover 9 which is formed into -~curved shape, can be open and closed up and down being disposed 4at the head support portion 2A, The head cover 9 Is pivoted at one side end so as to be open upward by a handle 12 Provided on the other side end. On the head cover 9, two sets of magnetic field generating uniLts are fixed In a curved state with their magnetic-pole -faces 11 facing downward.

At the end portion of the head support portion 2A, one set of magnetic field generating units 10 are fi xed by fixing metal 13 With their magnetic-pole f aces 1.1 8 facing inside the bed 1.

Said cover 3 is pivoted to an end of a support arm 41 by a support frame 42 at both sides in the longitudinal center portion, thereby the cover 3 is hanged horizontally in a balanced state. The base end of the support arm 41 is mounted inclinably on the upper surface of the wall 5 by a fixture 43, thereby the height of the cover 3 from the support face 2 can be set freely.

Said support arm 41 and said support frame 42 are connected pivotally, thereby the support frame 42 is 00#0 pivotable horizontally to the support arm 41.

00 OW",0 Said cover 3 is formed into a curved shape, the lateral center portion is high and Doth side ends are 0* low, on the basis. of the support -face 2 of the bed and 18 on the lower surface thereoU, a plural number of magneti field generating units 10 are fixed in parallel with their magnetic-pole faces 11 facing downward.

The magnetic field generating units 10 in the cover 3 and 9, and those on the bed 1 are electrically connected in parallel, an6 are turned ON and OFF by ft power switch on a control board 40 mounted to the wall On the control board 40, a plural number of time setting knobs 44 for setting the energizing time of the magnetic field generating units 10 for respective portions are A9 'K

provided.

When using the magnetic therapeutic apparatus having the above-mentioned configuration, first, after lifting and opening the cover 3, the user lies on the support face 2 of the bed 1 with the head positioning on the head support prtion the legs on the leg support portion 2C and tLue back on the back support portion 2B, Then, the arms are placed on the arm support portions 2D, after covering the cover 3 over the chest to abdomen and the head cover 9 over the head. Thereby, the body is entirely surrounded by the magnetic field generating 9o9 units 9o Next, when the power switch is turned ON, the 9 9 electromagnetic solenoids 17 of each magnetic field generating unit 10 are energized, thereby the magnetic fields are generated from the ends of the divided portions 22, 23 of the laminated iron cores 20, and exerted on respective portions of the body from the magnetic-pole faces 11. Furthermore, the electromagnetic solenoids 17 also generate vibration and heat, which act on the body to give the massaging and warming effects, In this case, since a large number of air holes f6 are formed in the support face 2 supporting the magnetic field generating units 10, a good permeability in 1
