DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair-type massager.

[0002]

2. Description of the Related Art Some chairs used in ordinary households have a seat portion and a backrest portion, and the backrest portion can be folded or reclined rearward. On the other hand, chair-type massagers with a built-in massage mechanism in the backrest, roller-type massagers mainly for legs, and portable massagers are sold and used.

[0003]

The inventor of the present application has noticed that although various types of conventional massagers have been developed, a chair-type massager has not been developed. We have created a seat-chair-type massager incorporating a compact and thin massage mechanism that can be stored in the back of a chair, and have already filed another application for this (Japanese Patent Application No. 11-207033).

[0004] This type of chair-type massage device has an elevating mechanism for moving the treatment element up and down as a massage mechanism. Therefore, when the treatment element portion of the massage moves upward, the center of gravity increases and the state is reclined. In addition to the fact that the weight of the user leans rearward, the user may fall down. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a seat-chair-type massage device capable of avoiding a danger that may be caused by falling backward.

[0005]

According to a first aspect of the present invention, there is provided a chair-type massager comprising: a seat;
It has a backrest portion and an elbow rest portion, and has a built-in massage mechanism in the backrest portion, and is provided with a fall prevention portion behind the seat portion. In the chair-type massager according to the second aspect, the elbow rest portion extends rearward from the seat portion.

[0006] In these chair-type massagers, the fall prevention portion is provided behind the seat portion, and the elbow rest portion extends rearward, so that the lower portion of the seat chair is stabilized. The backrest reclines, making it difficult to fall down even if a load such as body movement is applied. The chair-type massager according to claim 3 has a seat, a backrest, and an elbow rest, and has a built-in massage mechanism in the backrest. A pair of right and left sides of the seat is provided, and between the elbow rests, there is provided a part for preventing the seat from falling backward.

In this chair-type massage device, the lower part of the chair is stabilized by the fall prevention part by providing the fall prevention part to the rear of the seat. Further, the chair-type massager according to claim 4 is the one according to claim 3, wherein the fall prevention portion is a bar provided between the elbow rests. In this chair-type massager, by providing a closed-loop bar at the rear of the seat portion, the bar secures the stability of the lower part of the chair.

According to a fifth aspect of the present invention, in the chair-type massager, the bar has a substantially rectangular shape, and is formed so that the center in the width direction is located at the rearmost position, and the bar is located forward as it goes to the left and right. It was done. In this chair-type massager,
Even if a closed loop bar is provided, an extreme load is still applied to the rear, and if it falls, it falls obliquely with the bar in the width direction center as a fulcrum, so that the user does not fall right behind and hit the back of the head be able to.

[0009] According to a sixth aspect of the present invention, there is provided a chair massager having a seat, a backrest, and an elbow rest, wherein the backrest has a built-in massage mechanism. A pair of mounting portions is provided on the left and right sides of the seat portion, and a handle for carrying is provided behind the seat portion between the elbow mounting portions. In this seat-chair-type massage device, it is easy to carry by holding the grip means by hand.

According to a seventh aspect of the present invention, there is provided a chair-type massage device having a seat portion, a backrest portion, and an elbow rest portion, wherein the backrest portion has a built-in massage mechanism. A reclining mechanism is provided, and a lock mechanism is provided so as not to recline at a predetermined angle or more. Further, in the chair-type massager according to claim 8, the predetermined angle is set to an angle at which the user and the massage mechanism do not fall backward when both the user and the massage mechanism load backward.

By properly setting the predetermined angle, the massage device can be prevented from falling backward, and a massage at an appropriate head position can be ensured.
