Detailed Description of the Invention 【Technical field】

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a massager in which a treatment element is incorporated in a backrest of a chair or a bed, and more particularly to a massager in which the treatment element is movable along the backrest.

BACKGROUND ART As a massage machine for massaging the back of the human body,
The treatment element 2 is incorporated in the backrest 1 of the chair as shown in FIG. 1A or the bed or the like as shown in FIG. 1B, and the treatment element 2 is moved along the backrest portion 1. Freedom is provided. As shown in FIG. 8, the central portion of the back receiving portion 1 composed of the back receiving members 10 on both sides and the seat 11 arranged in a loosened state between the both,
In other words, position the treatment element 2 behind the seat 11
Massage is performed by pressing the back of the human body through the massager 2 via 11, and by moving the massager 2, the back of the human body can be massaged from the shoulder to the waist. Is. Considering the case where the massager 2 is used not as a massager but as an ordinary chair or bed, the presence of the massager 2 is an obstacle, so this type of massager 2 is used when not used as a massager. Can be retracted to the upper end or the lower end of the back receiving portion 1 that does not contact the body, but in this case, the seat 11 is loosened for the operation of the treatment element 2. In some cases,
Both sides of the body are supported by the back receiving parts 10,10, but the central part falls between both back receiving parts 10,10 as shown in FIGS. 9 and 10, and sinks, resulting in a comfortable posture. Couldn't keep up. For this reason, there are those in which a belt is provided on the back surface of the seat 11 or a lumbar support mechanism is separately provided, but it is difficult to achieve compatibility with the configuration for making the treatment element 2 movable.
It wasn't performing well.

[Object of the Invention]

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a massage machine that can take a comfortable posture when the treatment element is stored.

DISCLOSURE OF THE INVENTION

Therefore, according to the present invention, in the massage machine in which the treatment element is arranged in the central portion of the back receiving portion where the back receiving body is provided on both sides, and the treatment element is movable along the back receiving portion, And an air bag that bulges out in the center of the back receiving portion, which is the operation space of the treatment element when inflated, and occupies the operation space, and a control means that controls inflation and contraction of the air bag in conjunction with the operation of the treatment element. The air bag prevents the body from falling between the back receiving members in the back receiving portion, and the air bag does not expand and the treatment element does not get in the way. The contraction is automatically performed in association with the operation of the treatment element. The present invention will be described in detail below with reference to the illustrated embodiments.
As shown in FIG. 2 and FIG. 2, the back receiving portion 1 formed as a backrest of a chair has a back receiving member 10, 10 as a cushion provided on both sides thereof, and between the back receiving members 10, 10. The seat 11 is loosely attached to the seat 11, and the back cover 13 is a rigid body that covers the back of the seat 11. Rails 15 and 15 are installed on both sides of the seat along the back receiving portion 1, respectively.
The pair of massaging elements 2, 2 arranged in the back receiving portion 1 move along the rails 15, 15 and are driven to rotate by a shaft 20.
It is formed as an eccentric and inclined ring body,
The rotation massages the back of the person leaning against the back receiving portion 1 through the cover 13. In addition, an air bag 3 that is inflatable and contractible is installed in the back receiving portion 1. The air bag 3 is provided on the inner surface of the back cover 13,
A sheet 14 whose peripheral edge is airtightly fixed to the back cover 13, and when air is being discharged, as shown in FIG. 2, it is in a contracted state, but the lower end of the back receiving portion 1 When air is sent from the air pump P installed in the, as shown in FIG. 3, it inflates and overhangs between the back receivers 10 and 10 and was the operating space of the massaging elements 2 and 2 at the time of massage. Will be filled. FIG. 4 (a), FIG. 4 (b) and FIG. 4 (c) show changes in the state of the air bladder 3 due to intake and exhaust of air. The inflation and deflation of the air bag 3 configured as described above is controlled by the control circuit 4 shown in FIG. The control circuit 4 is connected to the operating device 5, and the treatment element 2 is passed through the treatment element drive circuit 6, the air pump P is passed through the pump drive circuit 7, and the air bag is passed through the exhaust valve drive circuit 8. The exhaust valves V for exhausting air 3 are connected to each other, and like the limit switch which is turned on when the treatment element 2 shown in FIG. 1 moves to the upper end of the back receiving portion 1. A treatment element position detection sensor S is connected. Here, the operating device 5 is provided with a switch SW for deciding a basic operation in addition to a switch for moving the treatment element 2 through the control circuit 4 and causing the treatment element 2 to perform various massage operations. ing. This switch SW allows the user to select "stop", "operation", and "storage". The control circuit 4 uses this switch SW.
6 is "stopped", as shown in FIG. 6, the operation of the treatment element 2 up to that point is stopped, the treatment element 2 is left in its stop position, and waits for the next switch SW operation input. State. When the switch SW is set to "operation", the exhaust valve V is opened, and then the treatment element 2 is caused to perform a predetermined operation. When the exhaust valve V has already been opened, the treatment element 2 is caused to perform a predetermined operation while maintaining this state. Switch SW
Is "stored", the control circuit 4 causes the sensor S
The treatment element 2 is moved to the upper end of the back receiving portion 1 until is turned on, the operation of the treatment element 2 is stopped at this position, and then the exhaust valve V is closed, and then the air pump P is operated for a predetermined time. To blow air into the air bladder 3 and set the air bladder 3 in the state shown in FIG. 1 and FIG.
It shifts to the standby state waiting for the next switch SW input. It should be noted that the exhaust valve V used is one that maintains a closed state even when the power is turned off. As is clear from the above, in this massage machine, when the treatment element 2 is stored in a position where it does not interfere with the input from the switch SW of the operation device 5, the air bag 3 is automatically inflated and the back support It is possible to prevent the body from sinking into the space between 10 and 10. Also, by setting the switch SW to "movement" from this stored state, when the massager 2 starts the massage operation, it is inflated until then. The air bag 3 contracts when the exhaust valve V is automatically opened so that it does not interfere with the operation of the treatment element 2.

【The invention's effect】

In the present invention, since the air bag that is inflatable and defensible and that bulges in the center of the back receiving portion that is the operation space of the treatment element and occupies the operation space when inflated, the expansion of the air bag causes the treatment element to move. It is possible to prevent the body from sinking into the operating space, and since the air bag here is controlled by the control means to expand and contract in conjunction with the operation of the treatment element, the user is concerned with the air bag. You can take a comfortable posture and start massage without being aware of it.
