  Further, a second urging means 35 for urging the foot insertion portion 10 toward the arm member 19 is provided between the distal end side of the arm member 19 and the foot insertion portion 10. The second biasing means 35 also has a second spring 36 (torsion spring) that winds the tip swing shaft 23 described above, and one end of the second spring 36 is below the foot frame 17 described above. The other end of the second spring 36 is locked to the front end side regulation pin 31. The distal end side regulation pin 31 on which the other end of the second spring 36 is latched is provided on the arm member 19 away from the distal end swing shaft 23, and if a biasing force is applied to the distal end side regulation pin 31. A moment for rotating (swinging) the arm member 19 around the tip swinging shaft 23 can be generated. Therefore, the second urging means 35 can also urge the foot insertion portion 10 toward the arm member 19 by applying the urging force of the second spring 36 to the distal end side regulation pin 31. Yes.

Next, an operation of moving the foot insertion portion 10 close to and away from the leg insertion portion 9 using the moving means 12 described above will be described.
First, an operation when the moving means 12 is operated on the footrest part 4 in the “degenerated state” to change the footrest part 4 to the “extended state” will be described.
As shown in FIGS. 5A and 6A, in the footrest part 4 in the “degenerated state”, the leg part insertion part 9 and the foot part insertion part 10 are close to each other in the vertical direction. The arm member 19 is inclined toward the front upper side.

In this “degenerated state”, the urging force of the first spring 34 of the first urging means 33 acts on the proximal end side regulation pin 29 and the urging force of the second spring 36 of the second urging means 35 is at the tip. Acting on the side regulating pin 31, the arm member 19 is biased in the upward swinging direction with respect to the leg insertion portion 9, and the foot insertion portion 10 in the upward swinging direction with respect to the arm member 19. It is energized.
Consider a case where, for example, a user U with a large physique sits on the chair-type massage machine 1 in which the footrest portion 4 is in the “degenerated state” and receives a massage. In this case, the user U who has a large physique has a wide space between the foot and the leg, and if the space between the leg insertion portion 9 and the foot insertion portion 10 of the footrest portion 4 is not increased, the user U The lower limb cannot be inserted into the footrest part 4.

  Therefore, the user U applies a load (leg force) to the foot insertion portion 10 by stepping on the foot insertion portion 10 and pushes the foot insertion portion 10 downward. Then, the distal end side of the arm member 19 swings downward with respect to the proximal end side against the urging force of the first urging means 33 and the second urging means 35 described above, and the foot insertion portion 10 is moved. It is possible to move away from the leg insertion portion 9 downward.

  In the “retracted” first swing restricting means 27, the base end side restricting pin 29 is in contact with the groove end on the rear end side of the first guide groove 30, but the inside of the first guide groove 30 is on the front end side. It is allowed to move towards. Also in the second swing restricting means 28, the front end side restricting pin 31 is in contact with the groove end on the front end side of the second guide groove 32, but it is allowed to move in the second guide groove 32 to the rear end side. Has been. Therefore, when the distal end side of the arm member 19 is swung downward with respect to the leg insertion portion 9 (base end side), the base end side regulation pin 29 comes into contact with the groove end on the front end side of the first guide groove 30. It moves, it moves until the front end side regulation pin 31 contacts the groove end of the rear end side of the 2nd guide groove 32, and the footrest part 4 can be changed to an "elongation state."

As shown in FIGS. 5B and 6B, in the footrest portion 4 in the “extended state”, the leg portion insertion portion 9 and the foot portion insertion portion 10 are separated so as to be spaced apart in the vertical direction. In addition, the arm member 19 described above is inclined toward the front lower side.
In the “elongated” first swing restricting means 27, the base end side restricting pin 29 abuts against the groove end on the front end side of the first guide groove 30 and swings the arm member 19 downward relative to the leg insertion portion 9. It is restricted from moving. Further, also in the second swing restricting means 28, the front end side restricting pin 31 abuts on the groove end on the rear end side of the second guide groove 32, and the foot insertion portion 10 can be swung downward with respect to the arm member 19. Be regulated. Therefore, if the first swing restricting means 27 and the second swing restricting means 28 are used, the foot insertion portion 10 is not separated from the leg insertion portion 9 beyond the “extended state”.

When the footrest portion 4 in the “extended state” is changed to the “degenerated state”, it is only necessary to remove the load (leg force) applied to the foot insertion portion 10 of the footrest portion 4.
That is, in the “extension state”, the urging force of the first spring 34 acting on the proximal end side regulation pin 29 increases from the “degenerated state” and the urging force of the second spring 36 acting on the distal end side regulation pin 31 is “ The arm member 19 is urged against the leg insertion portion 9 with a strong urging force in the upward swinging direction. Therefore, the arm member 19 swings upward by the urging force of the first urging means 33 and the second urging means 35 except for the load (leg force) applied to the foot insertion part 10 of the footrest part 4. Then, the foot insertion part 10 can be brought close to the leg insertion part 9 to return the footrest part 4 from the “extended state” to the “degenerated state”.

  If the above-mentioned moving means 12 is provided in the footrest part 4, the foot insertion part 10 can be freely moved close to and away from the leg insertion part 9, and the user U can adjust the leg part according to his / her physique. The distance between the insertion portion 9 and the foot insertion portion 10 can be adjusted. As a result, it is possible to perform treatments according to the physique of the user U, and perform sufficient massage for the user U having various physiques.

Further, if the moving means 12 described above is composed of the arm member 19 and the first urging means 33 and the second urging means 35 for urging the arm member 19, the cost is lower than that of means using a hydraulic cylinder or the like. Thus, the foot insertion part 10 can be moved closer to and away from the leg insertion part 9, and the price of the chair type massage machine 1 can be kept low.
Further, if the leg force applied to the foot insertion portion 10 is removed by pulling out the foot portion inserted into the foot insertion portion 10 or the like, the biasing force of the first biasing means 33 and the second biasing means 35 is removed. As a result, the arm member 19 swings toward the leg insertion portion 9 side, the foot insertion portion 10 comes close to the leg insertion portion 9, and the foot insertion portion 10 is automatically integrated with the leg insertion portion 9. Become. In a state where the foot insertion part 10 is integrated with the leg insertion part 9, the footrest part 4 has the smallest height in the vertical direction and is the most compact size. Therefore, the footrest part 4 can be accommodated smoothly and smoothly below the seat part 2, and the convenience of the chair type massage machine 1 can be enhanced.
[Second Embodiment]
Next, the chair type massage machine 1 of 2nd Embodiment is demonstrated.

As shown in FIGS. 7-9, the chair type massage machine 1 of 2nd Embodiment is not the arm member 19 like 1st Embodiment, The arm member 19 comprised by the parallel link mechanism 37 was used. It is set as the structure which makes the leg insertion part 10 approach / separate with respect to the leg insertion part 9 using.

  Moreover, the 1st biasing means 33 provided in the chair type massage machine 1 of 2nd Embodiment was provided between the base end side of the arm member 19 and the leg part insertion part 9 similarly to 1st Embodiment. This is the first spring 34 (torsion spring). However, unlike the first embodiment, the second biasing means 35 is not provided with a member such as the second spring 36, and the second biasing means 35 applies the biasing force of the first spring 34 to the parallel link mechanism 37. It is set as the structure transmitted to the foot | leg part insertion part 10 via.

Next, the moving means 12 of 2nd Embodiment is demonstrated.
As shown in FIGS. 7A and 7B, the arm member 19 provided in the chair type massage machine 1 of the second embodiment, that is, the parallel link mechanism 37 is provided on the protruding portion 24 of the leg insertion portion 9. The upper arm pivot plate 16 attached, the first link member 38 and the second link member 39 pivotally supported on the base end side of the upper arm pivot plate 16, and the first link member 38 and the second link member 39. The lower arm pivot support plate 18 pivotally supports the distal end side, and is composed of four members. The first link member 38 and the second link member 39 have substantially the same length in the longitudinal direction, and are attached in parallel so as to face each other.

  As shown in FIG. 8A and FIG. 8B, each of the first link member 38 and the second link member 39 is formed of two strips disposed at a distance in the left-right direction. Yes. The two strip plate members 39 a constituting the second link member 39 are arranged between the two strip plate members 38 a constituting the first link member 38. That is, the band plate member 38a of the first link member 38 and the band plate member 39a of the second link member 39 are arranged at a distance in the left-right direction, and may swing around an axis that faces the left-right direction. The band plate member 38a and the band plate member 39a have a structure that does not interfere with each other.

  Of these two link members 38, 39, the base end side of the first link member 38 provided on the outside is pivotally supported on the middle side in the vertical direction of the upper arm pivot plate 16. As with the first embodiment, the base end side of the first link member 38 can be swung freely at the pivot point on the base end side of the first link member 38 in the upper arm pivot support plate 16 provided in a forward projecting manner. A first proximal-side swing shaft 40 is provided for support. Further, the pivot point on the base end side of the second link member 39 in the upper arm pivot plate 16 is located on the lower front side than the pivot point on the base end side of the first link member 38 in the upper arm pivot plate 16. . The base end side of the second link member 39 is also swingably supported at the pivot point on the base end side of the second link member 39 in the upper arm pivot support plate 16, similarly to the first base end side swing shaft 40. A second proximal-side swing shaft 41 is provided.

  On the other hand, the front ends of the first link member 38 and the second link member 39 are also pivotally supported by the lower arm pivot support plate 18, respectively. The pivot point on the tip side of the first link member 38 in the lower arm pivot plate 18 provided in an upward projecting manner is located above the lower arm pivot plate 18, and this lower arm pivot plate 18. A first tip-side swing shaft 42 that swingably supports the tip side of the first link member 38 is provided on the upper side of the first link member 38. Further, the pivot point on the distal end side of the second link member 39 in the lower arm pivot support plate 18 is located on the lower front side than the pivot point on the distal end side of the first link member 38 in the lower arm pivot support plate 18. . Similarly to the first tip-side oscillating shaft 42, the lower arm pivot support plate 18 supports the tip side of the second link member 39 so as to be swingable. 2 A tip end side swing shaft 43 is provided.

  That is, as can be seen from the comparison between the “degenerated state” in FIG. 8A and the “extended state” in FIG. 8B, the four arms provided on the upper arm pivot plate 16 and the lower arm pivot plate 18 are provided. The pivot points, in other words, the first distal-side rocking shaft 42, the first proximal-side rocking shaft 40, the second distal-side rocking shaft 43, and the second proximal-side rocking shaft 41 are arranged in the horizontal direction. A parallel link mechanism 37 having four pivots on these pivot points is arranged so as to be always located at the apex of the parallelogram when viewed from the side.

  If such a parallel link mechanism 37 is used, the foot insertion part 10 is brought close to the leg insertion part 9 while maintaining the position of the pivot point of the second link member 39 relative to the pivot point of the first link member 38. It becomes possible to separate. That is, in the chair type massage machine 1 of the second embodiment, when the posture of the leg insertion portion 9 is in the horizontal state before the arm member 19 is swung, the posture of the leg insertion portion 9 is still after the swing. It remains horizontal, and the foot insertion portion 10 can be moved closer to and away from the leg insertion portion 9 without changing the posture of the foot insertion portion 10.

  Moreover, the chair type massage machine 1 of 2nd Embodiment is the 1st biasing means 33 between 1st end side of the arm member 19 and the protrusion part 24 of the leg part insertion part 9 similarly to 1st Embodiment. The first spring 34 is provided. However, the second biasing means 35 is not a torsion spring, but is configured to transmit the biasing force of the first spring 34 to the foot insertion portion 10 via the parallel link mechanism 37 described above.

  Furthermore, the chair type massage machine 1 of the second embodiment is provided with the first swing restricting means 27 composed of the first guide groove 30 and the base end side restricting pin 29 as in the first embodiment. However, unlike the first embodiment, the second swing restricting means 28 composed of the guide groove and the restricting pin is not provided. That is, the second swing restricting means 28 of the second embodiment applies the restricting force of the first swing restricting means 27 described above from the base end side of the arm member 19 via the parallel link mechanism 37 constituting the arm member 19. It is supposed to be transmitted to the tip side. In other words, the chair type massage machine 1 according to the second embodiment transmits the regulation force of the first oscillation regulating means 27 as it is without providing the second oscillation regulating means 28 with a member such as a guide groove or a regulation pin. Thus, the swing of the foot insertion portion 10 is restricted.

As described above, also in the second embodiment having the arm member 19 adopting the parallel link mechanism 37, the leg insertion portion is swinged similarly to the first embodiment by swinging the arm member 19 in the vertical direction. 9, the foot insertion portion 10 can be moved closer to and away from (elongated or retracted).
That is, the user U applies a load (leg force) to the foot insertion portion 10 by stepping on the foot insertion portion 10 and pushes the foot insertion portion 10 downward. Then, the distal end side of the arm member 19 faces downward with respect to the proximal end side against the urging force of the first urging means 33 and the second urging means 35 (the first spring 34 and the parallel link mechanism 37) described above. And the foot insertion portion 10 can be separated downward from the leg insertion portion 9.

  Further, if the leg force applied to the foot insertion portion 10 is removed by pulling out the foot portion inserted into the foot insertion portion 10 or the like, the first urging means 33 and the second urging means 35 (first urging means 35) The urging force of the spring 34 and the parallel link mechanism 37) causes the arm member 19 to swing toward the leg insertion portion 9 side, so that the foot insertion portion 10 comes close to the leg insertion portion 9 and the foot insertion portion 10 It is automatically integrated with the leg insertion portion 9.

  Note that the arm member 19 of the second embodiment does not have a structure in which the proximal end side and the distal end side of the arm member 19 are independently maintained as in the first embodiment, and the parallel link mechanism 37 is provided. Therefore, the urging force of the first spring 34 is always transmitted to the foot insertion portion 10 via the parallel link mechanism 37 constituting the arm member 19, and the urging force of the first spring 34 is interposed. In this way, the foot insertion portion 10 is drawn toward the arm portion side.

  In the chair type massage machine 1 according to the second embodiment described above, the distal end side regulation pin 31 and the second guide groove 32 are configured to stabilize the posture of the foot insertion portion 10 as in the first embodiment. There is no need to provide the second swing restricting means 28. Further, as the member constituting the second urging means 35, a member such as the first spring 34 of the first urging means 33 and the parallel link mechanism 37 is used. There is no need to provide a new member. Therefore, the configuration of the moving means 12 can be further simplified, and the number of parts can be reduced to keep the manufacturing cost of the apparatus low.

In addition, the following forms can be employ | adopted as a modification of 2nd Embodiment. For example, the arm member 19 can be attached by inverting the base end side and the tip end side upside down. That is, the distal end side of the arm member 19 is attached to the leg insertion portion 9, and the proximal end side of the arm member 19 is attached to the foot insertion portion 10. Even if the moving means 12 having such a configuration is adopted, the footrest portion 4 can be smoothly changed from the “degenerated state” to the “extended state”.

For example, as shown in FIG. 11 (a), when the footrest part 4 is changed from the “degenerated state” to the “extended state”, the partition part 14 that partitions the left and right leg part insertion parts 9 at the center remains fixed. Alternatively, a configuration in which only the side wall portion of the leg insertion portion 9 is moved downward (separated) integrally with the foot insertion portion 10 may be employed. When changing from the “extension state” to the “degeneration state”, the left and right side wall portions and the foot portion insertion portion 10 are brought close together upward with respect to the fixed central partition portion 14.

  Further, as shown in FIG. 11 (b), when the footrest part 4 is changed from the “retracted state” to the “extended state”, the left and right side wall parts and the central partition part constituting the left and right leg part insertion parts 9 are used. 14 may be moved downward (separated) and then moved upward by gripping only the central partition portion by hand. Then, when changing from the “extended state” to the “degenerated state”, the left and right side wall portions and the foot portion insertion portion 10 are moved upward together with the central partition portion 14 that has been moved upward as it is. (Proximity) is recommended.

Further, as shown in FIG. 11C, there is no problem even if the leg insertion portion 9 is configured to approach and separate from the foot insertion portion 10 while the foot insertion portion 10 is fixed.
11 (a) to 11 (c), the leg insertion portion 9 or the foot insertion portion 10 is moved by swinging the arm member 19 as in the first and second embodiments. However, the leg insertion portion 9 or the foot insertion portion 10 may be moved using a slide mechanism.
