Abstract
A vibratory massage apparatus comprises a treatment portion elastically carried on a support, a vibration generator including an electric motor for providing vibrations to the treatment portion, and a control circuit connected to the motor for causing vibratory amplitude of the motor to be varied, whereby a variety of vibratory stimulation can be imparted to the user's affected part placed on the treatment portion of the apparatus with an excellent massaging effect.
Claims1
A vibratory massage apparatus comprising
- a support means;
- treating means eleastically supported on said support means for treating the user's affected body part;
- vibration generating means held on the support means and including a motor for generating a vibratory motion which is transmitted to said treating means;
- a vibratory plate carrying said treating means;
- first spring means elastically coupling said vibratory plate to said support means;
- second spring means elastically coupling said vibration generating means to said vibratory plate;
- said vibratory plate, said vibration generating means and said first and second spring means defining a vibration system in which said vibratory plate is vibrated at a frequency close to a natural frequency of said vibration system;
- and
- a controlling means electrically connected to said motor for controlling said vibratory motion by cyclically varying its vibration amplitude;
- said controlling means including a first means for actuating said motor to produce a vibratory motion at a relatively smaller amplitude, a second means for actuating said motor to produce vibratory motion at a relatively larger amplitude, and means for actuating said first and second means immediately succeedingly and for imposing a halt period of zero amplitude immediately following the actuation of said second means to produce cyclical vibratory pattern comprising immediately succeeding periods of smaller, larger and zero vibratory amplitudes.
