Description

  The present invention relates to a chair-type massage machine, and more particularly to a chair-type massage machine provided with a leg rest provided with leg massage means.

  In a chair-type massage machine having a leg rest provided with a leg massage means, a switching means for switching the leg rest between a use position located in front of the seat portion of the chair and a storage position located below the seat portion. It is possible to prevent the leg platform from getting in the way when the leg platform is not used, and to place the leg platform in an appropriate position when using the leg platform. Can do.

  However, the conventional switching means has a fixed distance between the front edge of the chair seat and the leg rest when the leg rest is positioned at the use position. Some people could not receive an effective massage on the legs.

  In addition, the shape of the legs varies from person to person, but this cannot be dealt with, and in this respect as well, it has not been possible to receive an effective massage on the legs.

  The present invention has been invented in view of the above-described conventional problems, and it is an object of the present invention to provide a chair type massage machine capable of performing an effective massage regardless of individual differences in leg length and shape.

In order to solve the above problems, a chair type massage machine according to the present invention is:
A switching means which comprises a leg rest provided with a leg massage means, and which switches the leg rest between a use position located in front of the seat portion of the chair and a storage position located below the seat portion; A chair-type massage machine having front and rear position adjusting means for adjusting the front and rear position of the leg platform at a position, and detecting the angle of the leg platform that changes as the position of the leg platform is switched by the switching means The front / rear position adjusting means is formed by a slide mechanism that slidably holds the leg mount with respect to the switching means, and at least a part of the slide movement range of the leg mount. to a regulating portion for regulating the sliding operation by the stand of the own weight legs, in accordance with sliding movement restriction by leg stand of the own weight by the restricting unit to the detected leg stand angle by the detecting means To release the magnetostatic and it is characterized in that it comprises a release member that allows the sliding operation by the stand of the own weight legs. The front / rear position of the leg platform can be adjusted by sliding according to the length of the leg, and the regulation of the front / rear position adjustment by the regulating unit is performed according to the angle change accompanying the position change of the leg platform. It is released electromagnetically and allows the footrest to slide under its own weight .

In the chair type massage machine of the present invention, the front and back positions of the leg platform can be adjusted according to the length of the legs, and it is effective for the legs regardless of individual differences in the length of the legs. A massage can be surely given. In addition, it is possible to prevent the leg platform from inadvertently moving back and forth due to the presence of the restricting portion, and the angle change accompanying the position change of the leg platform when moving to the storage position, etc. Depending on the condition, the regulation is released electromagnetically so that the leg platform can slide under its own weight.Therefore, no separate operation is required to release the regulation, and the operation to move the leg platform is also necessary. Not .

  Hereinafter, the present invention will be described based on an embodiment shown in the accompanying drawings. As shown in FIG. 3, the illustrated massage machine includes a frame 81, a seat 80, an armrest 82, and a reclining backrest 83. A massage means (not shown) for massaging the back of the human body is built in the backrest 83 of the chair 8, and the leg rest 1 is disposed at the tip of the seat 80. The cylinder 9 in FIG. 1 is for reclining the backrest 83.

  As shown in FIG. 4, the leg mount 1 is a suspension of air bags 3 and 3 formed in a belt-like shape from a support 14 assembled with pipes, and has a U-shaped leg formed by the air bag 3. A leg (calf part) is placed in the storage groove 30, and in this state, the air supply / exhaust means 4 connected to the air bag 3 is operated to inflate and contract the air bag 3, thereby performing compression massage on the leg.

  Here, the leg mount 1 is attached to the frame 81 via a lasing tong mechanism 85 which is a multi-node link mechanism. A lazy tong mechanism 85 in which one end side of one link is pivotally attached to the frame 80 by a shaft 86 and one end side of the other link is attached to the frame 80 via a rotation link 87 is a rotation of the rotation link 87. Stretch with movement.

  Further, the support 14 of the leg rest 1 is pivotally attached to the lazy tong mechanism 85 and is connected to the shaft on the tip side of the lazy tong mechanism 85 via a link 88 so that the lathe tong mechanism 85 can be expanded and contracted. Accordingly, the posture is changed. When the lazy tong mechanism 85 is extended, the leg platform 1 is slightly lowered in front of the seat 80 as shown in FIG. When the lazy tong mechanism 85 is retracted, it is placed in a vertically oriented state below the seat 80 as shown in FIG.

Further, the leg rest 1 is not directly connected to the lazy tong mechanism 85 which is a switching means, but is connected via a slide mechanism. In a normal use state, the footrest 1 is positioned closer to the front due to its own weight. However, if the footrest 1 is pulled toward the chair side, the front end side of the seat 80 as shown by the chain line in FIG. Accordingly, the leg stand 1 can be brought close to each other, and therefore, it is possible to cope with individual differences in leg length.

The slide mechanism will be described. As shown in FIGS. 5 to 7, a pair of slide rails 10 that are long in the front-rear direction are provided on the lower surface of the leg platform 1, and the left and right connecting plates at the tip of the lazy tong mechanism 85 are provided. Sliders 91 and 91 are fixed on 90. The slide rail 10 is slidably engaged with the slider 91 covered. In FIG. 5 , M is a massage means disposed on the back 83 so as to be movable up and down, and C is an operating device.

Further, as shown in FIG. 8, an iron plate 96 that comes into contact with the inner surface of the slide rail 10 against the side surface of the slider 91 by the bias of the spring 94 and separates from the slider 91 by the bias of the electromagnet 95 disposed in the slide rail 10. Is provided so that slide regulation can be applied electrically .

Furthermore, by providing a sensor 97 for detecting the time of receiving the leg platform 1 shown in use during and 9 of the leg platform 1 shown in FIG. 9 (a) (b) a change in the angle, the leg platform 1 When shifting from the use state to the storage state, this is detected by the output of the sensor 97 and the electromagnet 95 is energized so that the slide restriction is released. Will return to the front and rear position.

It is a side view of an example of an embodiment of the invention. It is a side view same as the above. It is a perspective view which shows the whole structure same as the above. It is a front view of a leg stand same as the above. It is a perspective view same as the above . It is a bottom view of a leg stand same as the above . The slide rail and the slider are shown, wherein (a) is an exploded perspective view and (b) is a sectional view . (a) is a cross-sectional view when the electromagnet is off, and (b) is a cross-sectional view when the electromagnet is on . (a) and (b) are the partial side views same as the above .
