Abstract

A massaging machine formed as a mobile vehicle comprising a driving gear wheel for moving the vehicle by meshing with a flexible rack track belt which passes through the vehicle body and is held in tension, an electric motor for driving said gear wheel forward and backward, control levers provided on the front and rear ends of the vehicle body, changeover switches operated by said control levers, and a rotatable eccentric dead weight driven by the rotation of said driving gear wheel, in an arrangement that said vehicle is capable of automatically travelling forward and backward on said rack-track belt while vibrating itself during the travel.

Claims

1. A massaging machine, comprising:

a driving wheel for driving the vehicle of said massaging machine by holding a rack-track belt stretched in tension and by meshing with said rack-track belt;

an electric motor for rotating said driving wheel forward and backward; and

control levers provided to the front end and the rear end of said vehicle and also changeover switches respectively operated by said control levers;

in an arrangement that, when one of stoppers set on said rack-track belt acts on one of said control levers, said control lever operates one of said changeover switches to control electric current powering said electric motor causing said vehicle to travel on said rack-track belt.

2. A massaging machine in claim 1, wherein at least one of drive shafts between and including the drive shaft of said electric motor and the drive shaft of said driving wheel is mounted with an eccentric dead weight.

3. A massaging machine in claim 2, wherein said eccentric dead weight is mounted on the drive shaft of said electric motor.

4. A massaging machine in claim 3, wherein clutching mechanism is provided between said drive shaft of said electric motor and said drive shaft of said driving wheel.

5. A massaging machine in claim 2, wherein at least one drive shaft other than said electric motor drive shaft is mounted with said eccentric dead weight.

6. A massaging machine in claim 5, wherein clutching mechanism is provided between said electric motor drive shaft and said drive shaft of said driving wheel and at the same time said eccentric dead weight is mounted on at least one drive shaft between said clutching mechanism and said electric motor drive shaft.

7. A massaging machine in claim 6, wherein said clutching mechanism acts to transmit driving power to said driving wheel and also to release said driving wheel from said driving power.

8. A massaging machine in claim 1, wherein an upper pair and a lower pair of frames holding said rack-track belt are hinged on a shaft and movable to provide an opening.

9. A massaging machine in claim 1, wherein one or more rack-track belt guides are provided to the path of said rack-track belt through the body of said vehicle in an arrangement that said rack-track belt is guided by said guides to the surface of said driving wheel.

10. A massaging machine in claim 1, wherein press rollers are provided to push against said driving wheel said rack-track belt in mesh with said driving wheel and said press rollers are elastically supported.

11. A massaging machine in claim 1, wherein rolling wheels and supporting arms for supporting revolving shafts of said rolling wheels are provided under the front and rear ends of said vehicle and said supporting arms are rotational relative to said vehicle.

12. A massaging machine in claim 1, wherein each of said stoppers has a bumper pawl and also a clip for holding said rack-track belt so that each of said stoppers can be detachably attached to said rack-track belt.
