Vibrating apparatus

A vibrating apparatus of the type adapted to rest upon a supporting surface and to transmit a vibrational force through a cushioning medium which is in contact with the vibrational apparatus and the person of the user, the vibrational apparatus including a motor attached thereto and residing externally of the cushioning medium and the surface on which the apparatus rests, the improvement comprising:

• an upper elongate vibratory arm affixed at one end thereof in cantilever manner to a motor means,
• an lower elongate vibratory arm affixed at one end thereof in cantilever manner to a motor means,
• each said arms disposed a vertical distance from one another so as to avoid contact during vibratory motion thereof,
• the vertical distance of said arms from one another being greater intermediate the length thereof than at the ends thereof, so that maximum vibratory effect is transmitted from that section of the arms which is greater in distance from the opposing arm than is another section.

In an improved vibrator apparatus adapted to be installed with an intermediate cushioning surface between the apparatus and the user thereof comprising:

• a vibrating motor having electrical connection means extending therefrom for insertion into an electrical socket,
• first and second rigid arm means affixed to the motor and extending therefrom in cantilever fashion in such manner as to receive and transmit vibratory forces from said motor,
• said arm means arranged in respective planes separated from each other so that each is free to receive vibratory forces perpendicular to said planes from the motor and to transmit such forces along the length thereof, and
• connecting means affixing the remote ends of said cantilever arms together so that the vibratory force induced into one arm is transmitted to the other arm so as to cause amplification of the vibration thereof,
• said first and second arm means including an upper arm and a lower arm, each said upper arm and lower arm existing in independent, self-supporting relationship to the other arm and with sufficient distance therebetween as to allow vibrational movement of each without contact with the other,
• said lower arm being adapted to rest upon a supporting surface and said upper arm being adapted to contact the surface intermediate the apparatus and the person of the user, said upper arm being characterized by an elongate configuration when viewed from the top thereof, and being characterized by an arcuate configuration when viewed from the side thereof, said configuration from the side including a central section of concave arc with respect to the lower arm, said central concave arcuate section defining a static amplitude greater than the static amplitude of the arm on either side thereof, so that a vibratory force introduced to the arm at the supported end vibrates over a greater radial arc in the center of the arm than at either end thereof.
