Abstract:
A vibrator is disclosed for mounting on furniture in which a pair of vibrator motors is each mounted to an independent, long, relatively rigid resonator member capable of transmitting vibrations, the two long resonators for the respective motors being parallel to one another and mounted by non-rigid means such as a sheet of cardboard or springs to the remainder of the structure of the furniture. One form of complete unit comprises a non-rigid sheet containing two rigid rods each associated with an off-center vibrating motor, which underlies the surface of the furniture contacted by the user. A vibrator controller supplies the two vibrator motors with 60 Hertz pulsed DC current which is amplitude modulated at approximately 16 cycles per minute, with the modulation supplied to one motor 180.degree. out of phase with the other motor so that the user experiences the sensation of a moving wave. The user simultaneously receives a 16 cycle per minute alternating tactile stimulation, and a 60 Hertz audio wave which is amplitude modulated at 16 cycles per minute. The effect is somewhat similar to a Yoga chant and induces relaxation and a slower breathing rate. Other forms use rigid linear resonators attached to each vibrator and placed parallel to one another but not a permanent part of the furniture with which they are used.
Abstract:
A seat back for use in private or commercial vehicles is disclosed constituting a pulsation cushion formed having a plurality of expandable chambers interconnected by pressure limiting valves. The valves are responsive to fluid under pressure to produce a sequential rolling wave in the chambers to modify the cross-sectional amplitude of the seat back in the longitudinal and/or transverse direction thereby to massage the back of a person occupying the seat. An adjustable pulsing device is provided to control the supply rate of the fluid and the frequency and amplitude of pulsation.

The user simultaneously receives a 16 cycle per minute alternating tactile stimulation, and a 60 Hertz audio wave which is aplitude modulated at 16 cycles per minute.

Abstract:
A massage device having a substantially planar support of foamed plastic and a plurality of massaging elements in the form of halves of balls distributed uniformly about the support is disclosed. The massaging elements may be substantially the size and firmness of tennis balls and are secured to the support in closely-spaced parallel rows by sleeves in which the massaging elements are arranged end-to-end. The sleeves are gathered between adjacent massaging elements and are secured to the support between adjacent massaging elements.
Abstract:
A bed base having first and second members which are of generally U-shaped configuration so as to slidably telescope together to permit expansion or contraction of the bed base in the lengthwise direction. Locking mechanisms coact between the telescoping legs to lock the bed base in the selected expanded or contracted position. A sheetlike cover is anchored at one end of the bed base and extends along the upper surface thereof towards the other end, at which point an intermediate part of the cover wraps downwardly around a guide drum and then projects reversely toward the other end of the bed base. The lower free end edge of the cover is connected to a compensating mechanism which adjusts the cover length, namely by moving the cover upwardly or downwardly around the guide drum, so that the upper section of the cover always stretches tautly across the upper surface of the bed base irrespective of the adjusted expanded or contracted position.
Abstract:
An electromechanical vibrator driving device comprising a rhythm signal generator to produce rhythmic pulses in a pattern corresponding to a beat pattern of a selected music rhythm, the rhythmic pulses being amplified and then applied to the vibrator so that the vibrator generates a rhythmical vibration of the selected music rhythm. The rhythm signal generator comprises a rhythm pattern generator storing different rhythm patterns and providing pulses corresponding to strong beats and pulses corresponding to weak beats in a selected rhythm pattern, separately. The strong beat pulses and the weak beat pulses are processed by attenuators to have different amplitudes and are mixed to produce the rhythm signal.
Abstract:
A massager for massaging user's body with a pair of massaging elements pressed thereto, which comprises a main shaft carrying the massaging elements operatively with the shaft, a driving shaft shiftable vertically with respect to the axis with rotatable means carried at both ends for driving the main shaft and massaging elements, and means for controlling movements of the massaging elements in both directions of the main shaft axis and perpendicular thereto and rendering the movements to be startable always from a predetermined position, that is, from the inner side to the outer side of the user's shoulders or from his shoulder side on the back towards his waist, whereby the massaging elements can start from an optimum position for an intended massaging effect, ensuring an excellent convenience of use and a highly effective massaging operation.
Abstract:
A self-travelling vibration generator having a travelling frame movably supported by parallel rails, a lifting/lowering frame standing at substantially right angles with respect to the travelling frame, a plurality of eccentric rollers provided off-center with respect to a roller shaft rotatably provided on the lifting/lowering frame; and having such a construction that an induction motor is used for at least either of a motor for travelling the travelling frame or a motor for rotating the roller shaft so as to cause the eccentric rollers to give vibrations to a human body while travelling on the human body.
Abstract:
A roller-type massager having a pair of massage rollers rotatably mounted on a horizontal axle in parallel and spaced from each other within a chair back are vertically reciprocated along the spinal column. The horizontal axle is mounted on a screw housing and supported at both ends by a pair of guide rollers which are guided along a pair of vertical rails fixedly mounted within the chair back. The screw housing has a vertical through female screw threadably connecting with a vertical elongated screw bar which is rotatably mounted between the vertical rails and driven by a motor through a V-belt and pulleys transmission.
Abstract:
An electromassager for massaging action which includes a mechanism means for obtaining simultaneously both horizontally massaging movement along various locus and vertical tapping movement.
