Description

  The present invention relates to a chair-type massage machine, and more particularly to a chair-type massage machine provided with a massage means on a leg rest which is located forward of a seat and can support a lower limb.

  In the chair-type massage machine having the leg rest provided with the massaging means, as shown in FIG. 6, the leg rest 2 can be vertically rotated about the front edge of the seat 10. In this way, when the leg rest 2 is not used, the leg rest 2 can usually be stored below the front end of the seat 10.

  When the leg rest 2 is used, the leg rest 2 is turned up and down from the storage position so as to protrude forward of the seat portion 10, and at this time, a pair of left and right groove portions which are open in the front-rear direction and upward. If the lower limb is inserted into the lower limb 20, the massage is performed on the lower limb by the massage means, for example, the inflating and contracting air bladders 22, 22.

  However, in the chair-type massage machine provided with the above-mentioned leg rest 2, only a massage can be given to the lower limb, and a massage to a part such as an ankle or a sole must be performed by another massage machine for this purpose. .

  The present invention has been made in view of the above points, and has as its object to provide a chair-type massage machine that can massage not only the lower limbs but also the ankles and soles.

Thus, the present invention provides a leg rest which is disposed in front of a seat portion so as to be rotatable up and down and holds a lower leg of a seated person to the seat portion, and which is disposed so as to be rotatable up and down at a tip end of the leg rest. And a footrest for holding the toe of the occupant, the legrest and the footrest are provided with massage means for massaging the lower limbs and the toe of the occupant, and further interlocked with the rotation of the legrest. It is characterized in that there is provided interlocking means for rotating the footrest with respect to the legrest and increasing the angle between the legrest and the footrest as the legrest rotates upward . A footrest is provided at the tip of the legrest to hold the toe, and massage means is also provided on this footrest. If the legrest is rotated upward, the footrest also rotates with respect to the legrest. Make an angle with respect to the leg rest larger .

Further, if the interlocking means always keeps the footrest in a substantially horizontal state, it is not necessary to adjust the angle of the footrest with respect to the legrest when rotating the legrest, so that the usability can be improved.

And , when the axis connecting the leg rest and the foot rest and allowing the rotation of the leg rest with respect to the foot rest is located at the center of a circle inscribed in the front end and the upper end of the leg rest in a substantially horizontal state, It is possible to eliminate a possibility that a finger is pinched in a gap between the leg rest and the footrest.

  In addition, if the footrest holds the sole of the seated person when the legrest is vertically downward, the footrest can be held and massage can be performed.

The present invention can perform not only a massage for the lower limb held by the leg rest, but also a massage to the toe held by the foot rest, and a seated person can receive a more comfortable massage. In particular, if the legrest is rotated upward, the angle between the legrest and the footrest changes, so that the lower limb does not float off the legrest despite the presence of the footrest, and You can receive a massage for the part and a massage for the lower limbs.

  Hereinafter, the present invention will be described in detail based on an example of an embodiment. In FIGS. 1 and 2, a seat 10 is attached between a pair of side frames 11, 11 whose upper end faces are armrests. A leg rest 2 which is rotatable up and down by a link (not shown) is provided at a front portion of the chair 1 having a backrest 12 on the rear side of the chair 1. The leg rest 2 is rotated up and down around the front end of the seat portion 10 and is directed substantially horizontally as shown in FIG. 3 and downwardly as shown in FIG. 2 by the elastic supporting means 9 shown in FIG. It can be fixed at an arbitrary angle between the closed state and the closed state. The supporting means 9 may be a means that expands and contracts electrically, a gas spring that is urged in the direction of extension and that can be fixed to an arbitrary length by opening and closing a built-in valve. Alternatively, a link that can manually change the distance between both ends can be used.

Further, a footrest 3 is connected to a tip end of the legrest 2. The footrest 3, which is rotatable in the vertical direction by a shaft 21 with respect to the legrest 2, has its base end connected to the side frame 11 by a link 31, and the footrest 2 is moved from the state shown in FIG. When the footrest 3 is pulled rearward by the link 30 when the footrest 3 is rotated to the state shown in FIG. 5, the footrest 3 rotates about the shaft 20 with respect to the legrest 2 to increase the angle between the legrest 2 and the footrest 3. For this purpose, the state in which the footrest 3 forms substantially 90 degrees with the legrest 2 shown in FIG. 2 shifts to the state in which the legrest 2 and the footrest 3 shown in FIG. 3 are aligned in a straight line. Conversely, when the legrest 2 is returned from the state shown in FIG. 3 to the state shown in FIG. 2, the posture of the footrest 3 with respect to the legrest 2 returns to the original state of 90 degrees.

  Here, the leg rest 2 includes a pair of left and right grooves 20, 20 running in the front-rear direction, and in a substantially horizontal state shown in FIG. The air bag 22 is located on the bottom wall, and the footrest 3 also has a pair of left and right grooves 30, 30 running in the front-rear direction at the front part. The air bladders 32 are located on both side walls and the bottom wall, and these air bladders 22 and 32 are connected to the supply / exhaust means 4 installed and stored below the seat 10. The air supply / exhaust means 4 is capable of individually inflating and contracting each of the independent air bladders 22 and 32, and includes an air pump as a compressed air supply means, a distribution means including an electromagnetic valve and the like, and control of these. Control means.

  Now, in the state shown in FIG. 2, if the lower limb is fitted in the grooves 20, 20 of the leg rest 2 and the toes are fitted in the grooves 30, 30 of the footrest 3, and the air supply / exhaust means 4 is actuated, the inflatable and deflated air bag The massage according to 22 and 32 is performed on the lower limbs and the toes (including the soles), and the leg rest 2 and the foot rest 3 are extended as shown in FIG. If the lower limbs are fitted into the grooves 20, 20 and the ankles are fitted into the grooves 30, 30 in the footrest 3, and the air supply / exhaust means 4 is actuated, the massage by the inflating and contracting air bags 22, 32 can be performed on the lower limbs and ankles. This is done for the department.

  The rear portion of the footrest 3 is not provided with the grooves 30, 30 to allow the rotation of the footrest 3 with respect to the leg rest 2. Further, the shaft 21 for this rotation is located at a position substantially coincident with the center of a circle inscribed in the front end surface and the upper surface when viewed from the side of the leg rest 2 in a substantially horizontal state. A large gap is not always generated between the side wall of the groove 20 and the side wall of the groove 30 of the footrest 3. For this reason, there is no danger of fingers being pinched between the leg rest 2 and the footrest 3, and the massage target site by the air bladders 22 and 32 from the lower limb to the toe portion is almost continuously. Has become.

  FIG. 4 shows that the lower end of the leg rest 2 is sunk downward into the seat portion 2 and the leg rest 2 is rotated until the seat portion 2, the leg rest 2 and the foot rest 3 form a Z-shape when viewed from the side. Is shown. Since the length of the footrest 3 protruding from the front end of the seat 2 can be reduced, the front-to-rear length of the chair 1 as a whole in the stored state can be shortened. The possibility that the user will trip over or catch an object can be reduced.

  In the above embodiment, the massage means provided in the leg rest 2 and the footrest 3 is the air bags 22 and 32 which expand and contract. However, the present invention is not limited to this. It may be a means or a massage roller that is driven to rotate. Further, the massage means provided on the leg rest 2 and the massage means provided on the footrest 3 may be of different types.

  Further, the footrest 3 changes its posture as the legrest 2 rotates by providing the link 31. However, as shown in FIG. When the legrest 2 is shifted from a vertical state to a substantially horizontal state by providing a stopper 34 to be in contact with the legrest 2, the footrest 3 is also shifted to a substantially horizontal state by the stopper 34, and the legrest 2 is changed from the substantially horizontal state to the vertical state. At the time of shifting, the footrest 3 may return to a state of forming approximately 90 degrees with respect to the legrest 2 due to its own weight and contact with the floor. The stopper 34 may be provided not on the footrest 3 side but on the legrest 2 side.

It is a perspective view of an example of an embodiment of the invention. It is a fracture | rupture side view same as the above. It is a fracture | rupture side view at the time of extension of the legrest and footrest same as the above. It is a fracture | rupture side view of another example same as the above.
