  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the seat chair type massage machine of the present invention will be described in detail below with reference to FIGS.

  The seat chair type massage machine of the present invention is connected to the seat part 1, the backrest part 2 that is rotatably connected to one side of the seat part 1, and the other side of the seat part 1 to be freely rotatable. It is comprised from the leg part 3. FIG. The backrest 2 is provided with a massage mechanism 5 having a pair of left and right treatment fingers 4. The seat portion 1 incorporates a massage mechanism including a first vibrator 6 for loosening the thighs and the like by vibration. The leg portion 3 incorporates a massage mechanism including a second vibrator 7 for loosening the leg by vibration (see FIGS. 1 and 2).

By supporting a pair of first shafts 8 formed on the left and right sides of one side of the backrest portion 2 with a pair of first holes 9 formed in the protruding portion 28 on one side of the seat portion 1, the backrest portion 2 is rotatably connected to the seat portion 1. A first helical gear portion 10 having a smaller diameter than the first shaft 8 is formed on one of the pair of first shafts 8. A first drive unit 12 having a first worm shaft 11 that meshes with the first helical gear portion 10 as an output shaft is disposed in the seat portion 1, and the first worm shaft 11 is inserted into a hole 26 that is substantially perpendicular to the first hole 9. The first helical gear portion 10 and the first worm shaft 11 are engaged with each other. The 1st drive part 12 is comprised from a motor. When the first drive unit 12 is driven, the first worm shaft 11 is rotated, and by rotating the first shaft 8 via the first worm shaft 11 and the first helical gear portion 10, the backrest portion 2 is a seat portion. Rotate with respect to 1. A pair of first wheels 13 is mounted at the tips of the pair of first shafts 8 and fixed by wheel stoppers 27 (see FIG. 3).

  By supporting a pair of second shafts 14 formed on the left and right sides of one side of the leg 3 with a pair of second holes 15 formed on the other side of the seat 1, the leg 3 is attached to the seat 1. It is connected with respect to rotation freely. A second helical gear portion 16 is formed on one of the pair of second shafts 14. A second drive unit 18 having a second worm shaft 17 meshing with the second helical gear 16 as an output shaft is disposed in the seat portion 1, and the second worm shaft 17 is driven by the second drive unit 18. The leg 3 rotates relative to the seat 1 by rotating and rotating the second shaft 14 via the second worm shaft 17 and the second helical gear portion 16. The configuration of the second shaft 14, the second hole 15, the second helical gear portion 16, the second worm shaft 17, and the second driving portion 18 is the same as that of the first shaft 8, the first hole 9, and the first helical shaft shown in FIG. This is the same as the gear unit 10, the first worm shaft 11, and the first drive unit 12, except that there is no wheel at the tip of the second shaft 14. The 2nd drive part 18 is also comprised from a motor.

  On the other side of the leg 3, a third shaft 19 that passes through both the left and right sides of the leg 3 is rotatably supported. A substantially L-shaped crankshaft 20 extends from the tip of the third shaft 19, and a second wheel 21 is attached to the tip of the crankshaft 20 (see FIGS. 1 and 2).

  The third shaft 19 is biased by a spring 22 so as to rotate counterclockwise in FIG. Above the crankshaft 20, a ground contact detection means 23 for detecting whether or not the second wheel 21 of the leg 3 is grounded is disposed. The ground detection means 23 is composed of a pressure sensor or the like. When the ground detection means 23 detects pressure by touching an object, the ground detection means 23 is ON, and when the ground detection means 23 is not touching an object. Becomes OFF. A first spacer 24 is disposed on the back side of the backrest 2 and on the side of the back seat. A second spacer 25 is disposed on the back side of the seat portion 1 on the side opposite to the backrest portion (see FIG. 1).

  In the normal use state, the seat chair type massage machine configured as described above is in a sitting state by rotating the leg portion 3 so that the tip of the seat portion 1 is slightly lifted from the floor as shown in FIG. use. If you want to use a sitting chair type massage machine while sleeping, if you operate a switch in the expansion mode (not shown), the control unit (not shown) will make the angle between the seat 1 and the backrest 2 approximately 180 degrees. The first drive unit 12 is driven and the second drive unit 18 is driven so that the angle between the seat 1 and the leg 3 is approximately 180 degrees.

  If it carries out like this, a seat type massage machine will be in a bed state and can be used with a more comfortable posture. In this state, since the grounding of only the first wheel 13 and the second wheel 21 is not stable, the first spacer 24 and the second spacer 25 are grounded to improve the stability. Moreover, since the 1st spacer 24 and the 2nd spacer 25 are arrange | positioned in the position away from the 1st wheel 13 and the 2nd wheel 21, stability can be improved more (refer FIG. 6).

If you want to store the chair after you have finished using the chair-type massage machine, if you operate the switch in the storage mode (not shown), the control unit (not shown) will minimize the angle between the seat 1 and the backrest 2. The first drive unit 12 is driven and the second drive unit 18 is driven so that the angle between the seat 1 and the leg 3 is minimized. If it carries out like this, since a seat chair type massage machine becomes a substantially Z character shape and can occupy the floor area to occupy, storage property can be improved (refer FIG. 4). When the leg portion 3 is rotated, the second wheels 21 are rotated together to promote the rotation of the leg portion 3. Moreover, the 1st wheel 13 and the 2nd wheel 21 are also a trolley | bogie at the time of moving a seat type massage machine.

  When the seat chair type massage machine is put into the stowed state, the seat chair type massage machine may lose its balance and fall to the backrest 2 side. In this embodiment, the following control is performed. Prevents falling.

  The second drive part 18 is driven to minimize the angle between the seat part 1 and the leg part 3. The grounded second wheel 21 rotates clockwise against the biasing force of the spring 22. Therefore, the crankshaft 20 is in contact with the ground detection means 23 and the ground detection means 23 is in an ON state. When the angle between the seat portion 1 and the leg portion 3 is minimized, the seat-type massage machine is likely to fall to the backrest portion 2 side and the second wheel 21 is lifted. The urging force causes the crankshaft 20 to rotate counterclockwise. As a result, the crankshaft 20 does not come into contact with the ground detection means 23 and the ground detection means 23 is turned off (see FIG. 5).

  Therefore, when the angle between the seat portion 1 and the leg portion 3 is minimized, the seat-type massage machine is about to fall to the backrest portion 2 side, that is, the tip of the leg portion 3 is lifted. Can be estimated by the ON / OFF detection of the ground detection means 23.

  When the second drive unit 18 is driven to minimize the angle between the seat unit 1 and the leg unit 3, when the second wheel 21 is lifted, the ground detection means 23 detects this state and the first drive unit 12. Is driven to turn the backrest 2 toward the seat 1 to prevent the seat-type massage machine from overturning. When the second wheel 21 comes in contact with the ground again, the first drive unit 12 is stopped. After the angle between the seat 1 and the leg 3 is minimized, the first drive unit 12 is driven to minimize the angle between the seat 1 and the backrest 2.

  In this way, the second drive unit 18 is continuously driven, and the first drive unit 12 is driven auxiliary to prevent the overturn, thereby preventing the chair-type massage machine from falling. . Moreover, since the 1st drive part 12 and the 2nd drive part 18 can be driven substantially simultaneously, the time until it will be in an accommodation state can be shortened.

  When making a chair type massage machine into a bed shape, it is preferable to carry out in the reverse order of the stored order, but it is not necessary to be particular about it. In the worst case, even if the sitting chair type massage machine falls to the backrest part 2 side, if the leg part 3 is extended as it is, the sitting chair type massage machine becomes a bed state. Thus, by driving the 1st drive part 12 and the 2nd drive part 18 in relation, a series of operation | movement can be performed smoothly and operation can be simplified.

  In the present embodiment, the second driving unit 18 is driven to minimize the angle between the seat 1 and the leg 3, and then the first driving unit 12 is driven to seat 1 and the backrest 2. However, after the first drive unit 12 is driven to minimize the angle between the seat portion 1 and the backrest portion 2, the second drive portion 18 is driven to drive the seat portion 1 and the leg portion. The angle with 3 may be minimized to be in the storage state. In this way, there is no possibility that the seated chair type massage machine will fall down, so that the ground contact detection means 23 becomes unnecessary, and the seated chair type massage machine can be brought into the housed state without being turned over with a simple configuration. .

  Moreover, in this Embodiment, although the seat type massage machine was comprised so that it might be supported with the 1st wheel 13 and the 2nd wheel 21, you may comprise so that it may support with another support part.

Moreover, in this Embodiment, the backrest part 2 is provided with a pair of left and right treatment fingers 4 as the massage mechanism, and the seat part 1 and the leg part 3 are provided with vibrators 6 and 7. However, the massage mechanism is not limited to this. For example, the massage mechanism may be configured by an airbag that is inflated and deflated by supply and exhaust of compressed air. Moreover, although the seat part 1, the backrest part 2, and the leg part 3 are all equipped with a massage mechanism, it is sufficient to provide at least one of them.

It is a side view of the massage machine of the best embodiment for implementing this invention. It is a top view of the massage machine. It is a disassembled perspective view which shows the connection relation of the seat part and backrest part of the massage machine. It is the side view which made the massage machine into the accommodation state. It is a side view in the state where the leg part of the massage machine floated. It is the side view which made the massage machine into the bet state.
