ABSTRACT:
TECHNICAL BACKGROUND
The present invention relates to a water bed type massaging machine so adapted as to massage the body of a person. More particularly, the present invention relates to a water bed type massaging machine with a water bed filled with water or hot water, so designed as to enable massaging the entire body of a person lying on the water bed.
BACKGROUND TECHNOLOGY
Hitherto, International Application No. PCT/US90/03505 (International Publication No. WO90/15585) discloses a massaging machine of a bed type which can massage the entire body of a person.
This massaging machine includes a housing constituting a massaging chamber within the interior thereof with its top side open, a flexible sheet disposed on the open top side of the housing for supporting a person lying thereon, a fluid jet apparatus disposed in the massaging chamber for blowing jet streams towards the flexible sheet, and a pressurized fluid supply unit for supplying pressurized fluid to the fluid jet apparatus.
The fluid jet apparatus is constructed in such a manner that it can slide in a lengthwise direction through the inside of the massaging chamber and that it can massage the entire body of the person lying on the flexible sheet by allowing the jet streams to come into touch with the body of the person from the back side of the flexible sheet while sliding the fluid jet apparatus.
The conventional massaging machine as disclosed in the above-mentioned International Application No. PCT/US90/03505 (International Publication No. WO90/15585), however, allows the fluid jet apparatus to move only in the lengthwise direction within the massaging chamber.
Generally, when massaging the body of a person, higher massaging effects can be achieved by stimulating the areas of the body of the person being massaged, which are symmetrical on the left- and right-hand sides in a breadthwise direction of the person's shoulders with respect to the person's backbone by an appropriate magnitude of temperature. Accordingly, where the fluid jet apparatus can be moved only in the lengthwise direction within the massaging chamber, the such massaging machine cannot be said that it can provide sufficient massaging effects.
The such conventional massaging machine suffers from the disadvantages that the fluid supply apparatus and a device such as a pipe or the like for supplying pressurized fluid to the fluid supply apparatus are forced to become larger in size because it is so constructed as to support the person being massaged with the flexible sheet alone, so that the flexible sheet has to be sufficiently thick enough from the point of view of strength to support the body of the person being massaged yet it has to be sufficiently thin enough to allow the blowing pressure to be transmitted to the body of the person being massaged through the thickness of the flexible sheet.
Further, the flexible sheet having such a somewhat thick dimension may have the problems that it provides a poor feeling of resting on the flexible sheet and it cannot be fitted comfortably to the shape of the body of the person being massaged.
Although it is generally known that a higher massaging effect can be gained by carrying out the massaging while warming the body of the person being massaged, the thick flexible sheet is unlikely to be warmed readily by heating the fluid so that such a cold flexible sheet may reduce the massaging effects to a great extent.
Moreover, as the conventional massaging machine is equipped with no device for forcibly cooling down the temperature of warm water or the like filled in a water container, it may present the defect that the massaging cannot be carried out at an optimal temperature for a long period of time because the temperature of hot water or the like in the water container is caused to arise due to friction of the water filled therein when the massaging machine is operate d continually for a long time.
DISCLOSURE OF THE INVENTION
Therefore, the present invention provides a water bed type massaging machine, having a water bed formed in a box-shaped water container with an opening portion formed oh top thereof in which water or warm water is filled, and a flexible sheet disposed extending over the opening portion thereof in a water-tightly closed manner so as to allow a person to lie on the upper side of the flexible sheet, in which left and right nozzles are disposed in the interior of the water container to sprinkle water or warm water onto the bottom side of the flexible sheet and the left and right nozzles are disposed so as each to move, including rotate, in the heightwise direction of the height of a person being massaged while lying on the flexible sheet and in the breadthwise direction of the shoulder of the person being massaged.
In a preferred embodiment of the present invention, there is provided a water bed type massaging machine having a water bed formed in a box-shaped water container with an opening portion formed on top thereof in which water or warm water is filled, and a flexible sheet disposed extending over the opening portion thereof in a water-tightly closed manner so as to allow a person to lie on the upper side of the flexible sheet, in which a pair of left and right nozzles are disposed in the interior of the water container to sprinkle water or warm water onto the bottom side of the flexible sheet and the left and right nozzles are disposed in a relationship spaced apart along the breadthwise direction of the shoulders of the person being massaged while lying on the flexible sheet so as to be movable in the heightwise direction of the height of the person being massaged and further in which the pair of the left and right nozzles are disposed so as to be movable, including movable rotatably, which are symmetrically transversely on the left and right sides in the breadthwise direction of the shoulders of the person being massaged.
In another preferred embodiment, the present invention provides a water bed type massaging machine having the pair of the nozzles disposed so as to move, including rotate, in such a manner that the carrier is disposed in the water container so as to be movable in the heightwise direction of the person being i massaged, a pair of gears for moving the nozzles are supported axially in an engaging state on the upper side of the carrier so as to be rotatable, and the pair of the nozzles are disposed on the pair of the gears.
The water bed type massaging machine is further provided with a temperature adjustment means for adjusting the temperature of water or warm water filled in the water container.
