  Further, a pair of anti-tilt members 18 having a U-shaped cross section are fixed to the left and right ends of the base pipe 10 of the ottoman 6 so as to surround the side pipe 23 on the support portion 19 side. This prevents the ottoman 6 from tilting in the left-right direction with respect to the support portion 19.

  In addition, a pair of left and right coiled tension springs 33 are interposed between the support portion 19 and the ottoman 6 as urging means for urging the ottoman 6 in the sliding direction close to the seat portion 2 side. I am letting.

  The support portion 19 has a pair of support bearings 21 arranged on the proximal end side pipe 20 and a support shaft (not shown) extending in the left-right direction provided at the front position of the seat portion 2 of the massage machine body 1. ) And are freely fitted. As a result, the support portion 19 and the ottoman 6 supported by the support portion 19 have a vertical posture in which the tip side is lowered and substantially perpendicular to the seat surface of the seat portion 2, and the tip portion is lifted and substantially parallel to the seat surface of the seat portion 2. And a horizontal posture such that the vertical axis is pivotable about the support shaft.

  The lift mechanism 12 that controls the posture of the ottoman 6 by rotating the support portion 19 up and down is an elastic support means disposed between the support portion 19 and the massage machine body 1 (see FIG. 6). The detailed structure will be described later.

  The ottoman 6 of this example is fixed with a rack-like fixing member 17 that extends in parallel to the slide member 15, that is, in the sliding direction, and has a large number of locking grooves 16 arranged in the sliding direction. In addition, a stopper 29 which is rotatably installed on the connecting plate 24 on the support part 19 side is provided so as to be freely engageable with an arbitrary locking groove 16, so that the ottoman 6 can be supported with an arbitrary slide amount. The main part of the lock mechanism 30 which locks to 19 is comprised.

  As shown in FIG. 5, the stopper 29 is installed on the connecting plate 24 so as to be rotatable around the shaft 40. The biasing spring 41 is connected to one end of the shaft 40 and the shaft 40 is sandwiched. A flat plate-like locking piece 42 and a pulling piece 43 project from the end side. The locking piece 42 is a portion that is fitted into the locking groove 16 of the fixing member 17 from the side, and the locking piece 42 is locked by the biasing force of the biasing spring 41 that is a tension spring. It is urged in the direction of fitting inside.

  Each of the inner cables 44a and 45a of the pair of wires 44 and 45 for pulling the stopper 29 in the direction opposite to the fitting direction is connected to the pulling piece 43 positioned adjacent to the locking piece 42. One wire 44 is provided such that the inner cable 44 a is pulled by a pulling operation to the rear of the adjusting lever 25 arranged between the seat 2 and the elbow rest 4 of the massage machine main body 1. The other wire 45 has a structure in which the tip of the wire 45 is extended and connected to the lift mechanism 12 disposed between the massage machine main body 1 and the support portion 19. The connection part here is also mentioned later.

  Hereinafter, in the chair type massage machine of this example, when the ottoman 6 is rotated downward without returning to the original slide position, the structure for automatically releasing the lock of the ottoman 6 by the lock mechanism 30 will be described in detail. Describe.

  6 to 9 show the lift mechanism 12 of this example. The lift mechanism 12 is fixed to the worm shaft 27, which is connected to the massage machine body 1 below the seat 2 so that one end of the lift mechanism 12 can be turned up and down, a motor 28 meshing with the worm shaft 27, and the motor 28. The main body is composed of a columnar drive body 32 that is integrated with the motor 28 and is driven to advance and retreat along the worm shaft 27, and a cylindrical connection body 31 that is fitted to the drive body 32 so as to be slidable in the axial direction. Is forming.

  The connecting body 31 includes a connecting portion 31a that is pivotably connected to the support portion 19 and a contact portion 31b that contacts the driving body 32 and drives the connecting body 31 integrally with the driving body 32. And have. Accordingly, when the drive body 32 moves in the extending direction (left direction in FIGS. 7 to 9) by rotating the motor 28, the connecting body 31 is also pushed by this and moves integrally in the extending direction and is connected to the connecting body 31. The support portion 19 and the ottoman 6 supported by the support portion 19 are rotated upward. When the motor 28 is rotated in the reverse direction and the driving body 32 moves in the contracting direction (right direction in FIGS. 7 to 9), the connecting body 31 receiving the weight of the ottoman 6 and the support portion 19 follows the driving body 32. Then, it moves in the contraction direction, and rotates the support portion 19 connected to the connecting body 31 and the ottoman 6 supported by the support portion 19 downward.

  As described above, in the normal operation, the connecting body 31 is driven forward and backward integrally with the driving body 32. However, when the ottoman 6 is rotated downward without returning to the original sliding position, FIG. As shown in (c), the outer bottom surface of the tip of the ottoman 6 comes into contact with the floor surface 100, and the ottoman 6, the support portion 19, and the connecting body 31 connected to the support portion 19 stop moving on the way. On the other hand, since the driving body 32 is slidably connected to the connecting body 31, the driving body 32 contracts integrally with the motor 28 by the rotational driving force of the motor 28 as shown in FIGS. 7C and 8C. Continue moving in the direction.

  That is, after the ottoman 6 comes into contact with the floor surface 100, a driving force for separating the connecting body 31 and the driving body 32 is generated using the motor 28 as a driving source. The inner cable 45a of the wire 45 introduced into the lift mechanism 12 is pulled in conjunction with the separating operation of the connecting body 31 and the driving body 32 using the motor 28 as a driving source.

  Specifically, as shown in FIG. 9, the outer portion 45b at the tip of the wire 45 introduced into the lift mechanism 12 is fixed to the connecting body 31 side, and the inner cable 45a protruding from the tip of the outer portion 45b is connected to the drive body. The structure is fixed to the 32 side. With the above structure, after the ottoman 6 comes into contact with the floor surface 100, the inner cable 45a of the wire 45 is pulled by the driving force of the motor 28, thereby fitting into the locking groove 16 of the fixing member 17 as shown in FIG. The stopper 29 is rotated about the shaft 40 to release the engagement state of the locking piece 42 with the locking groove 16.

  In addition, by pulling the adjusting lever 25, the wire 44 different from the wire 45 similarly turns the stopper 29 around the shaft 40 to release the engaged state.

  Thus, in the chair type massage machine of this example, the ottoman 6 is rotated downward by the lift mechanism 12 while the ottoman 6 is slid in the direction away from the seat portion 2, and the ottoman 6 is in the middle of rotation. When it comes into contact with the floor surface 100, the inner cable 45a of the wire 45 is pulled by interlocking with the separating operation of the connecting body 31 and the driving body 32 in the lift mechanism 12. Since the lock mechanism 30 is unlocked by the operation of the wire 45, the ottoman 6 can be stored as it is to the initial position.

  In spite of the simple and low-cost structure described above, the pulling force of the inner cable 45a of the wire 45 is obtained by using the motor 28 of the lift mechanism 12, so that the releasing operation can be performed reliably. It is.

  Next, another chair type massage machine in the embodiment of the present invention will be described with reference to FIGS. In addition, detailed description is abbreviate | omitted about the structure similar to an example among the structures of this example, and it attaches | subjects a different code | symbol only about the characteristic structure different from an example, and is explained in full detail below.

  The lock release mechanism of the present example is identical to the example in that the lock mechanism is released by using the separating operation of the connecting body 31 and the drive body 32 in the lift mechanism 12, but the wire 45 is not used instead of the wire 45. The sensor 50 that detects the separation operation is used, and the lock mechanism 30 is unlocked by a solenoid 51 that operates by electric energy based on a signal from the sensor 50.

  That is, in this example, the sensor 50 that is a pressure sensor is disposed at the contact portion between the connecting body 31 and the driving body 32 in the lift mechanism 12, and the pressure detected by the sensor 50 becomes zero. Thus, the separation operation is detected. In the illustrated example, the sensor 50 is disposed on the drive body 32 side, but may be disposed on the connection body 31 side.

  As shown in FIG. 12, the solenoid 51 is arranged in the vicinity of the stopper 29 constituting the lock mechanism of this example, and the tip of the plunger 52 of the solenoid 51 is engaged with the pulling piece 43 of the stopper 29. The solenoid 51 pulls in the plunger 52 based on an electrical signal from the sensor 50.

  Thus, in the chair type massage machine of the present example, the ottoman 6 is rotated downward by the lift mechanism 12 while the ottoman 6 is slid in the direction away from the seat 2, and the floor surface is rotated in the middle of the rotation. In the case of contact with 100, the sensor 50 detects the separating operation of the connecting body 31 and the driving body 32 in the lift mechanism 12 and sends an electrical signal to the solenoid 51. Upon receiving the electrical signal, the solenoid 51 retracts the plunger 52, and the retracting operation rotates the stopper 29 about the shaft 40 to unlock the lock mechanism 30, so that the ottoman 6 can be stored as it is to the initial position. Is possible.

  Thus, in this example, since the solenoid 51 is actuated by an electric signal, there is an advantage that the unlocking is performed quickly after the rotating ottoman 6 contacts the floor surface 100.

  The sensor 50 is not limited to a pressure sensor, and may be any sensor using a limit switch or the like as long as it can detect a separation operation between the coupling body 31 and the driving body 32. Further, the mechanism for releasing the lock of the lock mechanism 30 is not limited to the solenoid 51, and any other configuration may be used as long as it operates by converting electric energy into mechanical motion.

  Next, another chair type massage machine in the embodiment of the present invention will be described with reference to FIG. In addition, detailed description is abbreviate | omitted about the structure similar to an example among the structures of this example, and it attaches | subjects a different code | symbol only about the characteristic structure different from an example, and is explained in full detail below.

  In the lock release mechanism of the present example, the protruding member 60 that protrudes from the portion that contacts the floor surface 100 of the outer bottom surface of the ottoman 6 and the wire 45 is connected in conjunction with the pressing operation of the protruding member 60. And a conversion mechanism 61 for performing a pulling operation.

  Here, the tip of the wire 45 is introduced to the vicinity of the protruding member 60 in the ottoman 6, and the tip of the outer portion 45 b of the wire 45 is fixed in the ottoman 6. The conversion mechanism 61 includes a rotating plate 63 that rotatably connects the inner cable 45a protruding from the tip of the wire 45 and the protruding member 60 about the shaft 62, and the protruding member 60 is rotated by rotating the rotating plate 63. The pushing force is converted into the pulling force of the wire 45.

  Therefore, in the chair type massage machine of this example, when the ottoman 6 is rotated downward by the lift mechanism 12 while the ottoman 6 is slid in the direction away from the seat 2, the rotation is performed. On the way, the protruding member 60 comes into contact with the floor surface 100. After the contact, the protruding member 60 is pushed into the ottoman 6 under the weight of the ottoman 6 and the support portion 19, and the rotating plate 63 is rotated in conjunction with the pushing operation, and the inner cable 45 a of the wire 45 is pulled. Operated. The lock mechanism 30 is unlocked by operating the wire 45 as in the example, and the ottoman 6 can be stored as it is to the initial position.

  That is, in this example, the weight of the ottoman 6 and the support portion 19 is used as a force for pulling the inner cable 45a of the wire 45.
