Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair with a footrest, and more particularly to a chair with a massage function for a footrest. 2. Description of the Related Art A chair with a footrest of this type is disclosed, for example, in Japanese Patent Application Laid-Open No. H11-299565. This is because a backrest is provided at the rear end of the seat, a footrest is provided at the front end, and a massage device such as an air bag is provided at the backrest. Are formed as a pair on the left and right, and a massage chair provided with a massage tool such as an air bag on both sides of the holding groove. Further, the backrest can be reclined back and forth, and the footrest is configured to be swingable up and down. When the backrest is tilted, the footrest swings upward and the backrest is raised. The two are interlocked so that the footrest sometimes swings downward.  The massage chair as described above is often used not only for performing massage but also as a simple chair. In particular, this type of massage chair often incorporates a soft cushion in the seat or the like, and the backrest has a reclining function, making it suitable for use as a sofa. ing. However, since the footrest has a groove for holding the foot on the upper surface, even if the massage function is not used, the footrest cannot be stably placed unless the foot is fitted into the groove. Had limited freedom of movement, which made it difficult to take a comfortable position. On the other hand, the footrest is pivotally supported at the front end of the seat, and the distance to the seat is substantially constant. Therefore, only a very limited part such as a calf or an ankle of a user sitting on the seat is massaged. I couldn't. Therefore, it has been difficult to respond to a request to massage other parts such as the soles of the feet. In view of such circumstances, an object of the present invention is to provide a chair with a footrest in which a footrest can be suitably used in both a case where a foot massage is performed and a case where the footrest is simply used as a chair. The present invention employs the following technical means to achieve the above object. That is, a chair with a footrest according to the present invention includes a chair body 1A having a seat 2 on which a user sits, and a chair body 1A.

The backrest 4 is made up and down and swingable about a pivot shaft 8 at the rear end of the seat 2 by a reclining mechanism (not shown). A massage mechanism 7 for performing massaging or beating massage is incorporated so as to be vertically movable. A massage mechanism 9 for performing kneading, tapping massage and the like is also provided inside the seat 2.
Is provided. The massage mechanism 9 and the backrest 4
The massage mechanism 7 can employ a configuration in which rollers, acupressure projections, and the like are mechanically moved, and a configuration in which an air bag (air cell) is inflated and contracted by supplying and discharging air. The chair body 1A has a support arm (support mechanism) 11 provided at the front end of the seat 2, and the footrest 5 is attached to the support arm 11.
As shown in FIG. 1, the support arm 11 of the present embodiment is formed in a U-shape when viewed from the front by a left and right side rod 12 and a lower rod 13 connecting lower ends of the left and right side rods 12. The upper end of the rod 12 is provided at the front end of the seat 2 so as to be swingable with the pivot 14 as a fulcrum. The support arm 11
Is configured to swing up and down in conjunction with reclining of the backrest portion 4 by a swing mechanism (not shown). The footrest 5 is formed in a rectangular shape in a plan view, and the upper and lower centers of the left and right sides thereof are rotatable with respect to the right and left rods 12 of the support arm 11 via a left and right pivot shaft 26. Installed. By rotating the footrest 5 around the pivot 26, both front and rear surfaces thereof can be turned upward (front side). As shown in FIG. 1A, one surface of the front and back of the footrest 5 is a massage surface 24 for performing massage on the foot, and the surface 24 includes a holding unit 20 for holding the foot, A massage tool 23 for massaging the feet held by the holding means 20 is provided. The holding means 20 is constituted by erecting support walls 21 on the left and right sides and the center of the massage surface 24, and forming a holding groove 22 between the support walls 21 for fitting and holding a foot. Have been. The massage tool 23 for performing massage massage is built in the opposing surface of each support wall 21. The massaging device 23 may be configured to perform massaging by swinging a long plate material in the length direction of the foot to the left or right, or may be configured to perform massaging with an air bag that expands and contracts due to supply and discharge of air. . A massage tool 23 may be provided on the bottom of the holding groove 22. As shown in FIG.
The other surface of the front and back of the footrest 5 is a substantially flat footrest surface 2.
The footrest 5 can be placed by turning the footrest 5 upside down and turning this surface upward. Therefore, when the chair 1 is used as a massage machine, as shown in FIG. 2A, the massage surface 24 of the footrest 5 is turned upward, and the foot is fitted into the holding groove 22 to hold the footrest 5. In the case of using as a simple chair without massage,
As shown in (b), by placing the foot with the footrest surface 25 of the footrest 5 facing upward, the foot can be freely moved to take a comfortable posture. Also, without using the massage function of the footrest 5, the massage mechanisms 7, 9 of the backrest 4 and the seat 2 are used.
When using only the footrest 5, the footrest surface 25 of the footrest 5
Can be used in a state of facing upward. The “substantially flat” that defines the shape of the footrest surface 25 indicates a state in which the footrest surface 25 does not have sharp and large irregularities such as the support wall 21 and the holding groove 22. The shape includes a shape in which the movement of the object is not limited, for example, a gently curved arc surface, a gently wavy shape, and the like. Preferably, a cushioning member such as a cushion is incorporated inside the footrest surface 25. The footrest 5 may be configured to be rotatable by being rotatable about the vertical axis with respect to the support arm 11. Further, as shown in FIG. 3, by being detachable from the support arm 11, the support arm 11 can be configured to be reversible. In the case of the illustrated example, a plurality of mounting projections 30 are provided on the left and right rods 12 of the support arm 11, and a mounting piece 32 having a mounting hole 31 is provided on the left and right sides of the footrest 5.
The footrest 5 is fixed to the support arm 11 by inserting the attachment protrusion 30 into the attachment hole 31 and attaching a retaining pin or the like to the insertion protrusion 30. In addition, the footrest 5 can be fixed to the support arm 11 by removing the footrest 5 by performing the reverse operation, performing the same operation as above after turning over the front and back. The footrest 5 is not limited to the one shown in the drawing, but may be detachably fixed to the support arm 11 by screwing, or may be detachably mounted on the footrest 5 side by providing a clip fitting to the support arm 11 or the like. Can be adopted. However, since the inversion by attaching and detaching the footrest 5 is troublesome and time-consuming, the configuration for rotatably supporting the footrest 5 on the support arm 11 as in the first embodiment is quick and simple. It is particularly useful for realizing operations. FIG. 4 shows the massage surface 2 of the footrest 5.
