Cl. 12833 2 Claims ABSTRACT OF THE DISCLOSURE A therapeutic spot pressure application apparatus having a cushioned article such as armchair and bed, a fluid pressure generating mechanism within or outside said article, means within said article adapted to be expanded by the fluid pressure from said pressure generating mechanism to thereby apply spot pressure to a number of points on the human body sitting or lying on said article.
The present invention relates to a mechanical spotpressure application apparatus which is used for therapeutic purpose.
Since olden times, finger-pressure treatment has been widely practiced in Japan as a part of the massage treatment by trained and licensed professional masseurs and 'masseuses.
With our life environment having been growing into more and more complicated one, month after month, with a kaleidoscopic flurriness in the recent years, and with the rapid development in the means of transportation of late resulting in a remarkable speed-up of vehicles, one cannot live without suffering a great deal of stresses imposed on his body and nerves. The ever-increasing fatigue accumulated in our body in our daily life has led to an acute demand for the development of an ideal spot-pressure application apparatus capable of mechanically providing the effect of finger-pressure treatment given by a Wellexperienced masseur at low cost.
On the other hand, the charges of masseurs and masseuses have leaped to such a high level, being stimulated by the hike of the livelihood standards of the general public, that a majority of workers such as day laborers and automobile drivers who use their muscles all day long and who, accordingly, acutely need quick recovery from fatigue are left without any handy and economical means available for relaxing their stiif shoulders and for relieving them of their accumulated fatigue. Development of such an eifective mechanical spot-pressure application apparatus as can be used in ones home, whenever desired, to relieve him of his fatgue and stilf muscles has been longed for also by elderly and aged persons.
There have been known several types of mechanical massaging apparatuses. However, none of them has ever successfully solved the foregoing requirements, because of their functional incompetency. Moreover, those massaging apparatuses of the prior art have been very little welcome by the users because of their failure in providing treatment in a comfortable manner due to their rigid structures and limited kinds of action and limited controllability.
It is, therefore, an object of the present invention to provide a most reasonable spot-pressure application apparatus designed so as to apply an appropriate amount of external stimulus of pressure force to various spots (hereinafter to be also referred to as treatment points, as required) of human body to facilitate the circulation of the blood and to activate 'slow metabolism, thereby accelerat- 3,483,862 Patented Dec. 16, 1969 ing quick recovery from fatigue and also providing the effect of reducing fat and superfluous flesh of man.
Another object of the present invention is to rovide an ideal spot-pressure application apparatus which can impart the effect of finger-pressure treatment to the various spots in the five major regions of human body, namely, the scrufi of the neck, back arms, thighs and legs from the upper portion to the lower portion in a manner as if the pressure is applied with the fingers of a professional masseur and which can be freely controlled of the intensity of the spot pressure force and which can impart its user a comfortable and resilient touch of finger pressure unlike the rigid, uncomfortable and limited massaging effect obtained from a conventional massaging apparatus, by the use of fluid pressure (air pressure, oil pressure or the like) system.

Description of the present invention will now be made on the structure of a preferred embodiment by referring to the drawings.
The apparatus of the present invention comprises an armchair 1 having a back-leaning section 2, a seating section 3, an arm-resting section 4 and a neck-resting section 5 and also an air-pressure generating means 6 contained in the space under the seating section 3.
The armchair 1 is provided with casters 1' at four corners of the bottom face thereof so that the armchair 1 may be freely transferred to a desired place in a room or from one room to another. The neck-resting section 5 is provided with an arrangement such that the neckreceiving member of the neck-resting section 5 may be pivotally swung about the axis of a handle 5' as the result of the forward and backward rotation of the threaded shaft of the handle 5' so that the position of the neckresting section 5 may be adjusted to the height of the upper half of the individual person sitting on the armchair 1.
The air-pressure generating means 6 provided in the lower portion of the armchair 1 is equipped with an air compressor 7 and a motor 8 for driving it. This motor 8 has a two-step V-pulley 9 which is secured to the shaft of said motor. The driving power of the motor 8 is transmitted from one of the steps of said V-pulley 9 to the V-pulley 11 of the air compressor 7 by means of a V-belt 10, and also transmited from the other of the steps of the pulley 9 to a speed change gear 13 by means of a V-belt 12. Further from said speed change gear 13 the driving power is transmitted to a speed reduction gear 14 by means of a V-belt 12'.
The air after being compressed by the air compressor 7 is transferred, through a pipe, into a pressure tank 16 to be accumulated therein, with an unloader 15 being provided at one portion of the pipe. This unloader is adapted to automatically discharge excess air from said pipe whenever the pressure of the compressed air accumulated in the tank exceeds a predetermined level so that an excessive compression of air in the tank is prevented.
Reference numeral 19 represents a valve means for distributing compressed air having, rotatably mounted therein through O-rings, a rotary member 20 having generally cylindrical shape and provided with one air-inlet bore 24 extending from one end face of said rotary member 20 for a distance thereinto in parallel with the longitudinal axis of said rotary member and also provided with two air-exhaust bores 28 extending from the other end face of said rotary member 20 for a distance thereinto in parallel with the longitudinal axis of said rotary member. An inlet member defining the mouth of the airinlet bore 24 is provided on the one end face of said rotary member 20. A pipe 22 extending from the pressure tank 16 is connected, by means of a rotary joint 23, -to said inlet member. An outlet member defining the mouths of said air-exhaust bores 28 is provided on the other end face of the rotary member 20. A V-pulley 21 is secured to said outlet member and is connected with said V-pulley 21 by means of a V-belt 18 running therebetween.
Six rows of holes each consisting of four spaced holes are formed radially through the peripheral outer wall of said air-distribution valve means 19 in such manner that each two adjacent rows of holes are disposed on said peripheral outer wall at an interval of 60 degrees from each other and relative to the longitudinal central axis of the cylinder of said valve means. A joint member 25 is provided for each hole so as to form a total of twenty-four ports, namely, a to a*, b to b 0 to c d to 11*, e to 2 and f to f. These ports are connected by means of connecting hoses 26 to a plurality of longitudinally expansible means 27 contained in the aforesaid sections of the armchair 1. As will be understood from FIG. 9, the longitudinally expansible means 27 are accommodated in the openings formed, in an appropriate manner, through resilient members 30 made of foamed synthetic rubber or synthetic resin which are covered by a cover 31 made of a leather or a cloth and constituting the faces of the respective sections of the armchair 1. Said longitudinally expansible means 27 are anchored by means of screws to steel frame member 1" secured to the bottom or back faces of said resilient members 30. Each of the longitudinally expansible means 27 is provided, at its upper end, with a spot-pressure application head 29 made of a vulcanized rubber.
Referential numerals 32 and 34 represent a remote control switch and a speed-change handle respectively which are mounted on a right elbow rest 4 of the chair 1 and numeral 33 indicates a pressure-adjustment handle mounted on a left elbow rest of the chair. The spot-pressure application heads 29 of the longitudinally expansible means 27 are so arranged that they project sightly beyond the face of the cover 31 at normal. times before the apparatus is put into operation.
Description will next be directed to the operation of the apparatus. First, the electric cord extending from the apparatus is connected to a plug socket of the power source, and thereafter the user sits on the armchair 1 ina manner as shown in FIG. 1. Then, the user turns on the remote-control switch 32. Whereupon, the motor 8 is connected to the power source and starts rotation, driving the air compressor 7 by means of the V-belt 10, resulting in that the compressed air is supplied to the pressure tank 16. On the other hand, the rotation of the motor 8is transmitted, via another V-belt 12, to the speed change gear 13, and thence to the speed reduction gear 14 through still another V-belt 12. The rotation which has been reduced of its speed by the speed reduction gear 14 is then transmitted, via a V-belt 18, to the rotary member 20 of the air-distribu i n a e mea s 19 so as to rotate said rotary member 20 at a low speed '=(which is approximately in'the range'of from 20m 40 r.p.m.). The compressed air coming from the pressure tank 16 is supplied to the respective longitudinally expansible means 27 first through the group of ports a a The air inlet bore 24 is then progressively brought into communication successively with the remaining groups of ports, namely, b b 0 0 d d e e and f f and thus the compressed air is successively distributed to the longitudinally expansible means 27 in each section of the armchair 1. The compressed air which has been supplied to the longitudinally expansible means 27 which communicates with the ports of the respective groups is then discharged outside the apparatus when said ports are brought into communication with the air-exhaust bores 28 after a predetermined lapse of time from the time of the termination of their communication with the air-inlet bore 24 due to the progressive rotation of the rotary member 20. Thereafter, the air-inlet bore 24 is again broughtinto communication with the pods due to the progressive rotation of the rotary member 20, allowing the compressed air to be supplied to the longitudinally expansible member 27, again. In the manner as has been described above, the continued rotation of the rotary member 20 causes the longitudinally expansible means 27 to repeat longitudinal expansion due to the supply of compressed air and contraction due to the exhaustion of the supplied air at predetermined cycles, resulting in cycled application and release of spot pressures to and from the body of the person sitting on the armchair 1.
Description will hereunder be directed to the manner in which spot pressures are applied to the body of the user as the result of the expanding and contracting actions of the longitudinally expansible means 27 which are effected according to the above-described procedure, by referring to FIG. 9. FIG. 9-A shows the longitudinally expansible means 27 in their normal state prior to being actuated, each of the means being of a height of H When the body of the user is seated on the armchair 1, the longitudinally expansible means 27 are compressed, due to the weight of the body of the sitting person imposed upon the means 27, to assume the state of FIG. 9-B having a height indicated by H and the surrounding resilient members 30 are also compressed to a state which is also shown in FIG. 9-B. With the subsequent supply of the compressed air into the longitudinally expansible means 27 through the connection hose 26, said means 27 are caused to expand longitudinally so as to assume a height indicated by H, in FIG. 9-C with the result that the spot-pressure heads 29 of the longitudinally expansible means 27 exert a pressure against the body of the sitting person by a distance of h. The upper faces of the longitudinally expansible cylinders 27 and the spot-pressure heads 29 thereof are provided with appropriate slits 27' and 29', respectively, so as to aid the contraction of the longitudinally expansible cylinders 27.
As is seen in FIG. 8, there are scattered a total of about sixty longitudinally expansible means 27, which correspond to the tips of the fingers of a masseur, throughout the entire faces of the armchair 1 in accordance with the locations of the so-called treatment points which are superficially scattered on the human body including the hollow of the nape on the neck. Namely, there are eight of them in the zone covering the area from the neck to the shoulders; sixteen of them in the zone covering the area from the back to the behind of stomach; twelve 'of them in the zones of both arms; and twenty-four of them in the zones covering the thighs and the legs. It is needless to say that the number of these longitudinally expansible means 27 may be increased or decreased so as to meet the desire of the users. 7
As has been described in detail in the above, the apparatus of the present invention is operated in the following simple prOcedure. Specifically, the user, after seating on the armchair, is required only to manipulate the switch 32 located on the right arm of the chair, whereupon the apparatus is actuated to effect the spot-pressure actions which begin with the upper portion of the scruff of the neck and downwardly to the shoulders; from the upper portion of the back downwardly to the region of the behind of stomach; from the upper arms to the lower arms, and so on, as if the user is receiving a finger-pressure treatment from a well-trained masseur, and the spotpressure treatment is repeated in cycles continuously for a desired length of time until the user turns off the switch 32. In the event that the user feels that the force of the spot-pressure actions exerted by the longitudinally expansible means 27 is weak, it is only necessary that the user turns the pressure-adjustment handle 33 toward the side marked strong. This manipulation of the handle 33 tightens the spring of the unloader connected to said handle 33, which, in turn, will serve to elevate the pressure of the compressed air in the pressure tank 16, and accordingly, the internal pressure of the longitudinally expansible means 27 which is imparted by the supplied compressed air will be elevated, resulting in an increase in the force of the spot-pressure applied to the body of the user. In case it is desired to weaken the spot-pressure force, it is only necessary for the user to manipulate said pressure-adjustment handle 33 in the reverse way. Furthermore, in case it is desired to increase the speed or the cycle of the spot-pressure actions of the means 27, this end is achieved by turning the speed-change handle 34 in the desired direction, whereupon the speed-change ratio of the speed-change gear 13 changes to alter the rotational speed of the rotary member 20, and thus the expansion-contraction speed of the longitudinally expansible means 27 can be freely changed as desired. By an appropriately combined manipulation, as described, of the speed-change handle 34 and the pressure-adjustment handle 33, the user can obtain a desired sensation of spotpressure treatment in a manner required by the user such as (a) strong but slow, (b) strong and quick, (c) weak and slow, and (d) weak but quick.
As has been described, the apparatus of the present invention provides resilient and rhythmical spot-pressure treatment in an effective manner substantially throughout the required areas of the muscles, and enables the user to be relieved of his fatigue during a limited period of time while the user is relaxing on the chair. The apparatus of the present invention also provides an outstanding advantage that a greater range of spot-pressure treatment effect can be obtained by changing the material with which the spot-pressure heads are made and by changing their shape as required. The present invention has further advantages that its entire mechanism is relatively simple in structure and arrangement, and that it can be applied not only to such armchair as has been described but also to various kinds of articles such as beds, mattresses and cushions by incroporating appropriate numbers of the longitudinally expansible means therein and also that the apparatus of the present invention can be modified to comply with any posture of the user as required so as to meet the individual purposes. Furthermore, in the event that it is desired to give spot-pressure treatment simultaneously to a number of persons in an institution such as a large factory, as is called industrial massage, the invention is advantageous in that it can utilize the compressed air which is routinely used in the factory so that a large number of spot-pressure application apparatuses in the form of, for example, armchair and containing no air compressors may be installed side-by-side relations and in rows. Thus, the present invention which utilizes fluid pressure can be termed as a most reasonable and ideal invention.
In the embodiment illustrated, the longitudinally expansible means 27 consist of bellows-type expansible cylinders. It is to be understood, however, that the cylinders 27 may be substituted by operative cylinders of other type utilizing fluid pressure such as air pressure and oil pressure, or they may consist of expansible air-tight bags made of a material such as rubber and vinyl. It is further to be understood that various modifications of the invention may be made by those skilled in the art without departing from the spirit of the present invention.
