Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is characterized by combining compressed air and mechanical movements mainly for the purpose of obtaining a combined effect of massaging, apportioning, acupressure, etc. around the spine and spinal cord of the human body in the sitting position. The present invention relates to a complex massage machine.

[0002]

2. Description of the Related Art Heretofore, a chair-type device called a massage machine or a massage machine for the purpose of obtaining a massage or a massage effect on the back of a human body in a sitting position has been widely available on the market. The mechanism is such that the roll provided on the back plate of the chair-type base body reciprocates up and down, or the hitting rod operates to mechanically tap or knead the shoulder or back, and its back plate. And / or a plurality of air sacs are arranged in a horizontal direction on a seat, and a kneading or kneading effect is obtained by sequentially supplying and discharging pressurized air to the air sacs.

[0003]

The former, that is, the one by mechanical movement has a strong sense of intuition against the pressure, and there is much resistance in use for women and women and the elderly, and the pneumatic type. Has a problem in that it is inferior in terms of the rubbing effect, although it gives the user a soft feeling due to its contractility and moderate surface stimulation.

[0004]

In view of the above-mentioned circumstances, the present inventor has combined one of the characteristics of the above mechanical mechanism with the superiority of the pneumatic type to form one massager. It succeeded in enhancing the distribution or massage effect in which each characteristic was combined.

That is, at least the center of the back plate of the chair-type base body, which is opposed to the center of the back plate at regular intervals, and which is movable up and down,
A means is used in which air sacs are disposed on both sides of the rubbing mechanism so that the air sacs can expand or contract at the same time or separately by supplying / exhausting compressed air.

Further, a means is used in which the above-mentioned rubbing member can be projected by a certain amount while moving up and down. Furthermore, the left and right air sacs are composed of a plurality of upper and lower air sacs independent of each other, and the air sacs can be expanded or contracted simultaneously or alternately in the upper and lower directions.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a compound massage machine according to the present invention will be described in more detail in accordance with one embodiment shown in the drawings.

In FIG. 1, reference numeral 1 is a seat 1a and a back plate 1b.
A chair-type base body having a back plate 1b, a rubbing member made of a roll or the like that can vertically move a central portion of the back plate 1b by a rubbing mechanism to be described later, and 3 a rubbing mechanism of the back plate 1b. Is a plurality of air sacs that are placed opposite to each other.

The air sacs 3 of the back plate 1b are divided into left and right rows with the orbit of the rubbing body 2 interposed therebetween. The left and right air sacs 3a, 3a arranged at the uppermost stage are the neck muscles. In addition to being provided at the position to pinch, each left and right row including the top row,
It is composed of a plurality of upper and lower independent air sacs 3a, 3b, 3c ..., Each of which is equipped with a pressure hose 4 leading to a compressor (not shown), and communicates from the compressor to each air sachet via a distributor or the like. The compressed air can be supplied to and discharged from each row.

That is, the air sacs in each row are simultaneously supplied to the left and right uppermost air sacs 3a and 3a to be inflated, and then the internal air pressure is discharged to allow the air sacs to be contracted.
Air is supplied to and discharged from 3b, and the air sacs of this stage are simultaneously expanded and contracted so that the air sacs of the lower stage are sequentially transferred.

The air bag 3 in the present invention is not limited to being buried in the back plate 1b surface of the base 1 described above, and a plurality of air bags 3'are provided in the lateral (horizontal) direction on the seat 1a surface. By doing so, at the same time, an effect such as kneading can be imparted to the buttocks and upper limbs (thighs), and further two kneading mechanisms 5 with air sacs 5a opposite to each other are attached to the front surface 1c of the seat 1a, and these are connected to each other with a hose. It is also free to connect to the above-mentioned compressor via 4 to perform massage and loosening of the dorsal side of the lower limbs (calf).

In addition, the method of distributing the compressed air to each air sac is not limited to that of the above-described embodiment, and various combinations of the distribution order are possible, and the user can arbitrarily select it by remote control operation. It was done like this.

Next, the operation mechanism of the above-mentioned rubbing member 2 will be described. FIG. 2 shows an example in which the roll-type rubbing member 2 is used. In FIG. 2, 6 is a machine having inner folding edges 6a on both sides. Case,
Reference numeral 7 denotes a sprocket shaft pivotally supported by side plates 6b near both ends of the machine casing 6 in the longitudinal direction. Two sprocket wheels 7a are rotatably arranged on each shaft at equal intervals. A motor (M) using one shaft 7 as a drive shaft and an appropriate power transmission means such as a belt or a chain (C).
Connected to.

Further, inside the machine casing 6, an endless chain 7b is attached between the front and rear sprockets 7a, and a spindle block 2b supporting a roll shaft 2a and a shaft end roller 2c are mounted on the major axis of the endless chain 7b. is there. In this case, the chain 7b
By slightly shifting the mounting positions of the two roll shafts 2a fixed above to make them unequal in distance, the two rubbing bodies 2 are both on the back side of the chain when the rubbing body 2 is stopped. By doing so, the protrusion of the rubbing body 2 on the back plate surface when not in use can be prevented, which is convenient for obtaining a kneading or kneading effect by the air bag.

In the present invention, the vertically movable sliding rubbing member 2 has a structure in which the roll shaft 2a is fixed to the endless chain 7b and a roll is provided on the roll shaft, as in the above example. A non-rotating rubbing body 2 and a drum in which a chain or rope can be wound instead of the front and rear sprockets 7a are provided, and the rubbing body fixed between them is drumed by a limit switch or the like. It also includes a structure in which the rubbing body is reciprocated by reciprocally rotating.

On the other hand, a rail plate 6c which guides the shaft end roller 2c in a rollable manner is provided below both inner folded edges 6a of the machine casing 6, and a chevron shape is formed at an appropriate position of the rail plate 6c. The portion 6d is raised so that the shaft 2a and the rubbing body 2 can be thrust into the rail plate 6c at a constant height via a shaft end roller 2c rolling on the rail plate 6c. However, in this case, the shaft end roller 2 is attached to the inner folding edge 6a located immediately above the chevron portion 6d.
It is necessary to form the protruding port 6e of c.

In principle, the air sacs and the rubbing mechanism of each of the above parts are covered and concealed by the front cloth (not shown) of the base 1, and the rubbing body 2 and the air sacs 3 of each part.
The start and stop of 3'and the like, or the selection of the strength or weakness or the operating portion can be easily performed by the user by operating the remote controller while sitting down as described above.

[0018]

According to the present invention, by adopting such a structure, the sliding effect of the sliding frictional body that rolls up and down across the spinal cord of the user in the sitting position provides a massage effect and promotes blood circulation around the spine. Not only the function is exerted, but also the sliding friction body can project by a certain amount, so that in addition to the above-mentioned function, the kneading effect, that is, the comfort of acupressure can be brought about.

On the other hand, by vertically arranging the air sacs on both sides of the rubbing body, the air sacs arranged independently on the upper and lower sides are sequentially inflated in response to the supply and discharge of the pressure air simultaneously performed in the same row.
While repeating contraction, it exerts a kneading effect by its wide surface, comfortably kneads the back muscles, and in combination with the above-mentioned light rubbing or kneading function by the rubbing body, recovers muscle fatigue on the entire back. It produces a special effect.

In this case, by synchronizing the expansion / contraction operation of the air bag with the traveling speed (position) of the rubbing body, a function of arbitrarily adjusting the contact force of the rubbing body with the skin can be obtained. . In addition, when a kneading mechanism is used in combination with a seat and / or an air sac on the front of the seat, a full-body massage or full-body massage that simultaneously massages and loosens the buttocks and the dorsal side of the upper and lower limbs can be obtained. .
