  • ABSTRACT F THE DISCLOSURE A therapeutic message assembly designed for association with a iieXible body supporting cushion and operative to apply therapeutic massage over a selected area and length of the flexible cushion supported body; the massage assembly embracing one or more rows of resilient massage applicators rotatably mounted in cantilever suspension on a resiliently flexible frame fixed to a vibratory motor suspension bar, the ends of the bar being attached to the midsections of a pair of arched springs whose terminal ends are secured to a rigid baseframe, and which cooperate to provide an applicator supporting carriage which is resiliently exible in vertical, longitudinal and transverse directions and operates to maintain the resilient applicators in uniform pressure contact with the undulating body supporting cushion; together with a carriage supporting tracking frame having means for adjustably securing the same to the cushion framework to thereby maintain ⁇ the applicators in rolling contact with the flexible body supporting cushion, the tracking frame also including spaced guide rails and associated means for slidably supporting the carriage baseframe for smooth reciprocating movement thereon.
  • Therapeutic massage has also been applied to a substantial area of a persons body through a resilient body supporting cushion which contains a vibration transmitting grid or core structure which is vibrated by a vibraton producing generator attached to one end of the core or grid as shown in U.S. Patent 3,019,785.
  • the vibrations produced by the vibration generating motor is transmitted through the grid or core structure and resilient body supporting cushion, to the persons body reclininv thereagainst.
  • the massage vibrations are not uniformly distributed and applied to all areas of the persons body supported upon the cushioned surface, due to the fact that the cushion supporting ing spring structure or grid vibrates with maximum intensity in the area immediately surrounding the point of attachment of the vbration producing generator to the spring structure or grid, with decreasing intensity of vibration transmission to the spring structure or grid as the distance from the point of attachment of the generator thereto increases.
  • vibration transmission through the resilient cushion to the persons body reclining thereagainst is most intense immediately over or adjacent to the point of attachment of the vibration producing generator, and graduallly decreases over other body areas more remote from the point of motor attachment.
  • Massage tables have also been suggested, whose cushioned body supporting surface present a medial slot or opening covered by only a thin membrane, and over which the body area to be massaged is positioned.
  • stationary or traveling massage applicators project upwardly into the massage table slot and into Contact with the underface of the relatively thin membrane.
  • Massage vibrations transmitted to the applicators are applied substantially directly to the body area through the relatively thin membrane, whose intended purpose is to reduce contact friction on the skin -of the patients body.
  • Such massage tables usually require an attendant to control and adjust the massage applying mechanism, often produce skin burns on the patients body, are uncomfortable to the patient, and apply massage with irregular and varying intensity to the body area positioned over the membrane covered slot.
  • the lslot area is also necessarily limited, and only a limited area of the persons body can be massaged in one treatment, and requires the reclining person to shift position in order to place another body area over the massaging slot.
  • the therapeutic massage assembly made in accordance with this invention is designed to overcome the deficiencies of prior massage systems, and is operative ⁇ to generate and flexibly transmit through a resilient body supporting medium and to a persons body supported thereby, therapeutic massage of controlled and uniform intensity to all undulating areas of the human body reclining on and supported by the lresilient medium.
  • This advanced massage assembly is designed for association with the resiliently cushioned framework of a bed, lounge, couch, massage table, or the cushioned backrest of an upholstered chair, and includes a series of parallel rows of resilient massage applicators which receive vibrations of uniform intensity transmitted from an electrically controlled vibration generator and transmits these Vibrations through the resilient body supporting cushion for uniform application to all areas of the irregularly shaped human body supported upon the resilient cushion.
  • the resilient massage applicators of this invention form component parts of a massage carriage contained within the cushioned framework, and which is designed to apply and uniformly transmit their vibrations to the inner surface of and thence through the resilient cushionin-g, to the cushion supported body with uniform intensity.
  • the massage assembly constructed in accordance with this invention is also flexibly responsive to body pressure exerted against the applicators through the resilient cushion, irrespective of the undulating shape and form of the human body reclining thereagainst.
  • the massage carriage is adjustably supported and mounted within the cushioned framework, and includes a pair of spaced and longitudinally extending arched springs whose terminal ends are iixed to and resiliently supported by a carriage baseframe.
  • a suspension bar extends transversely between the arched springs, with the end portions of the bar secured to the crowned mid-sections of the arched springs.
  • a pair of spaced and longitudinally extending and flexibly resilient applicator supporting members are rigidly secured at the mid portions thereof to the transverse suspension bar to which a vibration generating motor is rigidly but removably secured. The motor generated vibrations are thus substantially fully transmitted to the transverse suspension bar and thence to the flexibly resilient members.
  • One or more transverse axles or shafts are positioned on both sides of the transverse suspension bar, with the end portions thereof tixed to and supported by the flexibly resilient members.
  • a row of resilient massage applicators are supported by each axle or shaft, and are positioned directly adjacent to the inner liner of the resilient body supporting cushion.
  • Means, adjustably connected to the framework of the cushioned body supporting frame, provide support for the baseframe of the carriage, and whereby the several rows of massage applicators may be adjustably brought into vibration transmitting contact with the inner liner of the resilient body supporting cushion.
  • the weight or pressure exerted by the occupants body against any area of the resilient cushion causes the cushion liner to sag and apply a corresponding body pressure against the massage applicators in contact therewith,
  • the exertion of uneven body pressure against the massage applicators is transmitted to the tiexibly resilient members and arched supporting springs.
  • the arched and ilexible supporting springs permit the longitudinal flexible members to flexibly tilt and adjust in response to body pressure transmitted to the resilient massage applicators, so that the several rows of massage applicators will exert uniform pressure against the inner liner of the resilient cushion.
  • the paired longitudinal iiexible members which support the several rows of resilient massage applicators are also preferably made of spring steel, and subject to flexure when body pressure is transmitted thereto, and which thus function to further enhance the uniformity of contact pressure exerted by the several rows of resilient massage applicators against the exible liner of the resilient body supporting cushion.
  • the massage carriage of this invention may be held in stationary position, so that the massage vibrations are uniformly transmitted to only a selected portion of a persons body reclining against the resilient cushion, a greater area of the persons body may be treated by the provision of means for reciprocating the carriage at a controlled speed along the entire length of a persons back or a persons stomach #and chest area or a persons side.
  • the carriage supporting and reciprocating mechanism of this invention comprises a tracking frame adjustably connected to the cushioned framework and which slidably supports and guides the carriage base frame in its reciprocating movement.
