JP 2004-8257 A

  In the chair type massage machine of Patent Document 1, a leg unit is provided on the rail and a foot unit is provided on the slide rail, and the slide rail is slidably fitted on the rail. That is, both the weight of the leg unit and the force applied to the leg unit, and the weight of the foot unit and the force applied to the foot unit are applied to the rail. In particular, in the state where the slide rail is extended most with respect to the rail, the force acting on the rail from the foot unit through the slide rail becomes very large because the point of action is far away, and the rail and slide rail There is a possibility that the shakiness becomes large and the sliding motion of the foot unit becomes unstable.

  An object of the present invention is to provide a chair type massage machine capable of stably sliding a leg unit and a foot unit.

In order to solve the above problems, the chair type massage machine of the present invention is
A chair-type massage machine in which a foot massage unit is arranged on a swing frame that is swingably disposed on the front end side of a seat portion on which a user sits,
The foot massage unit has a leg unit for massaging the calf of the user and a foot unit for massaging the toe of the user,
The swing frame includes a first slide rail in which the leg unit is slidably disposed, a second slide rail in which the foot unit is slidably disposed,
Leg urging means for urging the leg unit in a direction that always draws the leg unit toward the seat side between the swing frame and the leg unit;
Between the leg unit and the foot unit, there is a foot urging means that urges the foot unit in a direction that always pulls the leg unit in the direction of the leg unit,
The foot urging means has a lower urging force than the leg urging means.

According to the chair type massage machine of the present invention, the first slide rail and the second slide rail are directly connected to the swing frame, respectively, the leg unit can be slid on the first slide rail, and the foot is used as the second slide rail. The unit is slidable.
That is, since the leg unit and the foot unit are separately slidably supported by the first slide rail and the second slide rail, the force acting from the leg unit is applied only to the first slide rail, The force acting from the unit for use is transmitted only to the second slide rail.
Therefore, even if the leg unit and the foot unit are slid in the extending direction, the force acting on the foot unit is not applied to the first slide rail, so that the foot unit can be slid stably. it can.

Further, the leg unit is constantly urged by the leg urging means in the direction of being pulled toward the seat portion side. Further, the foot unit is always pulled toward the leg unit side by the foot urging means. Each of the foot units is pressed against the urging force of the foot urging means when the user depresses the foot unit with the soles as desired. While moving in the direction away from the unit for leg, the leg unit is pulled by the leg unit and moves in the direction away from the seat against the biasing force of the leg biasing means.
Thereby, the user can receive a massage by the leg unit and the foot unit at a desired position corresponding to the length of the leg.
In the present invention, the foot urging means has a lower urging force than the leg urging means. Therefore, when the user steps on the foot unit with the sole, The weak foot urging means extends, and the foot unit starts moving before the leg unit. Thereafter, the leg urging means extends and the leg unit moves.
Therefore, when using the foot unit and leg unit without moving them too much, only the foot unit can be moved relatively lightly. There is no burden.

As shown in the figure, the swing frame (60) includes a swing shaft (61) that is rotatably fitted to brackets (18) and (18) on the seat portion (12) side, and the swing shaft (61). The vertical frame (62) (62) fixed in the direction perpendicular to the swing shaft (61) at a position near the center of the length direction of the swing shaft at positions near both ends of the swing shaft (61). The first slide rail (52) (52) fixed in the direction orthogonal to (61), and the swing shaft (52) between the vertical frame (62) (62) and the first slide rail (52) (52) 61) a second slide rail (54) (54) fixed in a direction orthogonal to the end frame, and an end frame connecting the ends of the frame (62), the first slide rail (52) and the second slide rail (54) (63)
A lock mechanism (70), which will be described later, is attached to the vertical frame (62).

  As shown in FIGS. 5 to 8, the first slide rail (52) is a U-shaped cross-section rail that opens toward the rear surface side. As shown in FIG. In order to reduce the contact resistance with 37), protrusions (52a) are formed in the length direction.

  The second slide rail (54) is a U-shaped rail that opens inward (on the right side in FIG. 8) as shown in FIGS. 5 to 8. As shown in FIG. In order to reduce the contact resistance with the slide frame (47), a protrusion (54a) is formed in the length direction.

The leg unit (30) is attached to the leg base frame (36), and the leg base frame (36) is for a leg that is slidably fitted to the first slide rail (52) (52). Slide frames (37) and (37) are provided. The slide frames for legs (37) and (37) are U-shaped cross-section frames that open inwardly, and protrusions (37a) for reducing contact resistance with the first slide rails (52) and (52). ) Are formed. (53) is a stopper formed on the first slide rail (52). When the leg unit (30) moves most forward, it comes into contact with the leg slide frame (37). Try not to move on.
A leg locking plate having a plurality of positioning grooves (38a) (38a) for positioning a leg unit (30) in mesh with a locking mechanism (70) described later at the center of the leg base frame (36) (38) is deployed.

  Also, leg urging means such as a coil spring (39) is provided between the leg base frame (36) and the swing shaft (61) of the swing frame (60), so that no load is applied. Then, the leg unit (30) is biased in the direction of being pulled in the direction of the swing shaft (61) (seat (12) side).

The foot unit (40) is attached to the foot base frame (46), and the foot base frame (46) is a hollow that fits slidably on the second slide rail (54) (54). Foot slide frames (47) (47) formed in a rectangular shape are provided. The foot slide frames (47) and (47) are respectively formed with protrusions (47a) for reducing the contact resistance with the second slide rails (54) and (54).
At the center of the foot base frame (46), a foot lock plate is provided with a plurality of recessed positioning grooves (48a) (48a) for positioning the foot unit (40) by meshing with a lock mechanism (70) described later. (48) is deployed. The foot lock plate (48) is disposed so as to overlap the above-described leg lock plate (38) in the front-rear direction (direction perpendicular to the paper surface in FIGS. 6 and 7). In the embodiment, as shown in FIG. 5, the leg lock plate (38) is positioned forward.

In addition, foot urging means such as a coil spring (49) is provided between the leg base frame (36) and the foot base frame (46). 40) is biased in the direction of being pulled in the direction of the leg unit (30).
The urging force of the foot urging means (coil spring (49)) is weaker than the urging force of the leg urging means (coil spring (39)). In the case of a coil spring, the spring strength of the leg coil spring (49) is smaller than the spring strength of the leg coil spring (39), or the number of coil springs compared to the leg coil spring (39), The number of leg coil springs (49) may be reduced. The urging force of the foot urging means is desirably about 50 to 80% of the urging force of the leg urging means.
The actions and effects of the leg urging means and the foot urging means will be described later.

  As shown in FIGS. 6 to 10, the lock mechanism (70) is provided on one vertical frame (62) of the swing frame (60). The lock mechanism (70) has a lock base plate (71) attached to the vertical frame (62) and a lock member (72) pivotally supported (74) on the lock base plate (71). is doing.

The lock member (72) has a lock piece (73) whose tip is bent so as to mesh with the positioning grooves (38a) (48a) of the leg lock plate (38) and the foot lock plate (48). .
Further, a tension spring (75) is stretched between the lock member (72) and the lock base plate (71) so as to be biased in the direction of the positioning grooves (38a) (48a).
The lock member (72) can be operated by the wire (76) composed of the inner wire (76a) and the outer wire (76b). One end of the outer wire (76b) is attached to the lock base plate (71), and the other end is connected to a lock operation portion (79) provided on the armrest (16) or the like. One end of the inner wire (76a) is connected to the lock member (72), and the other end is connected to the lock operation portion (79).
When the inner wire (76a) is pulled by operating the lock operation part (79), the lock member (72) rotates around the shaft support part (74) against the urging force of the tension spring (75) to lock The piece (73) is detached from the positioning grooves (38a) (48a). When the pulling force on the inner wire (76a) is released, the lock member (72) is engaged with the positioning grooves (38a) (48a) by the biasing force of the pulling spring (75).

  When the lock member (72) is engaged with the positioning groove (38a) (48a), the leg unit (30) and the foot unit (40), that is, the leg base frame (36) and the foot base frame (46) is fixed with respect to the swing frame (60) and cannot be slid. On the other hand, when the locking member (72) is removed from the positioning groove (38a) (48a), the leg unit (30) and the foot unit (40), that is, the leg base frame (36) and the foot base frame (46). ) Is slidable with respect to the swing frame (60).

  In addition, as shown in FIG.9 and FIG.10, it is desirable to pivotally support the small diameter roller (73a) on the positioning groove (38a) (48a) side of the lock piece (73). Thus, even when the lock piece (73) is disengaged from the positioning groove (38a) (48a) and reengaged, it does not fit into each groove and rides on the jetty (38b) (48b) between the grooves. The roller (73a) rolls on the jetty (38b) (48b), guides the lock piece (73) to the positioning groove (38b) (48b), and meshes with the positioning groove (38b) (48b). Can do. Further, by using the roller (73a) as a resin molded product, there is an advantage that it is possible to suppress the collision noise between the lock piece (73) and the positioning grooves (38b) (48b).

  The foot massage unit (20) having the above structure is configured so that the tip of the foot massage unit (20) is moved upward by the swinging means (not shown) while the user is seated on the seat (12). When the lock member (72) is removed from the positioning grooves (38a) and (48a) from the state shown in FIG. 9 by operating the lock operation portion (79) (swing in the direction of arrow A in FIG. 1) ( The leg unit (30) and the foot unit (40) can slide. In this state, when the user steps on the bottom surface (45) of the foot unit (40) with the sole of the foot, the coil springs (39) and (49) resist the urging force as shown in FIGS. The leg unit (30) and the foot unit (40) receive a force in the sliding direction.

  At this time, since the coil spring (49) having a small spring strength first extends, first, the foot unit (40) slides the foot slide frame (47) with respect to the second slide rail (54), It moves in a direction away from the swing shaft (61) (extension direction). In addition, if the foot unit (40) is further moved in the extension direction after the coil spring (49) is extended to some extent, the coil spring (39) having a large spring strength starts to extend, and the leg unit (30) is extended in the extension direction. Move to follow. The length of the longest extension of the foot unit (40) is regulated by the foot slide frame (47) hitting the end frame (63) of the swing frame (60).

  As described above, the foot unit (40) has a lower biasing force than the leg unit (30), that is, the foot unit (40) is biased by the foot coil spring (49) having a smaller spring strength. When only (40) is moved slightly, only the foot coil spring (49) with a small spring strength is extended, and only the foot unit (40) can be moved relatively lightly. Therefore, there is no burden when a short person or a small person below the knee uses it.

When the user slides the leg unit (30) and the foot unit (40) to the desired position and operates the lock operation part (79) to release the inner wire (76a). 10, the lock member (72) is rotated by the urging force of the tension spring (75), and the lock piece (73) is fitted into the positioning groove (38a) (48a), and the leg unit (30) is connected. The foot unit (40) is positioned (see FIG. 9).
In this state, by operating the massage means provided in the leg unit (30) and the foot unit (40), it is possible to receive a massage at a desired position corresponding to the length of the foot of the user.

  After the massage is finished, release the stepping force of the sole on the bottom surface (45) of the foot unit (40), operate the lock operation part (79), pull the inner wire (76a), and remove the lock piece (73). When removed from the positioning grooves (38a) and (48a), the urging force of the coil springs (39) and (49) pulls the leg unit (30) and the foot unit (40) toward the swing shaft (61), As shown in FIGS. 1 and 6, the state returns to the shortest state.

  As described above, according to the present invention, the user can receive a highly effective massage by moving the leg unit (30) and the foot unit (40) to a desired position. The leg unit (30) and the foot unit (40) are independently supported by the first slide rail (52) and the second slide rail (54) connected to the swing frame (60), respectively. Both the leg unit (30) and the foot unit (40) are excellent in stability when sliding, and also in the extended state.

  The leg unit (40) is slid in the extending direction by appropriately adjusting the spring strength of the coil springs (39) and (49), which are urging means for the leg unit (30) and the leg unit (40). When this is done, the stationary position of the leg unit (30) can be adjusted. That is, the foot unit (40) is pushed and extended by the sole, and the foot unit (40) is stretched by the sole so that the urging force of the coil spring (49) does not return to the swing shaft (61) side at that position. In this state, the leg unit (30) can be adjusted to a desired position regardless of the foot unit (40). Desirably, the spring strength of the coil springs (39) and (49) is approximately half of the sliding distance of the foot unit (40) when the foot unit (40) is slid. Set it so that it slides by the distance.

  In the above embodiment, the common locking member (72) is engaged with the locking plates (38) and (48) of the leg unit (30) and the foot unit (40), so that each unit (30) (40) Since positioning is performed, the number of parts can be reduced.

  In the above, the leg lock plate (38) and the foot lock plate (48) are provided on both the leg unit (30) and the foot unit (40). The leg locking plate (38) can be omitted. In this case, when the foot unit (40) is slid, the spring strength of the coil spring (39) (49), which is the urging means, is applied to the leg unit (30) by the pulling force of the coil spring (39) (49). You can rest and massage at the appropriate position.

  The chair type massage machine (10) of the present invention can be fixed with the foot massage unit (20), that is, the leg unit (30) and the foot unit (40) extended, and a foot massage unit ( 20) can be swung. Using this configuration, the heavy chair type massage machine (10) can be easily moved on the floor.

14 to 16 show an embodiment in which a moving means is provided in the chair type massage machine (10) of the present invention.
As shown in FIGS. 14 to 16, the rear end of the base (11) extends rearward, and main rollers (80) are disposed on the left and right of the extended end. Normally, when moving the chair type massage machine (10), grab the upper end of the backrest (14), tilt the chair type massage machine (10) backward, and only the main roller (80) is on the floor. The floor can be moved in a grounded state. However, in this case, it is necessary to hold the chair type massage machine (10) in a well-balanced manner, so it is necessary to move over a distance or move on a stepped, inclined, or uneven floor (including carpets and tatami mats). Was not easy.
Therefore, as shown in FIGS. 15 and 16, a sub roller (82) is provided as a moving means at the lower rear end of the foot unit (40), and as shown in FIGS. 17 and 18, the base (11) and A fixing means (90) for fixing the leg unit (30) was provided.

  The sub-roller (82) can be pivotally supported at the lower rear end of the foot unit (40), for example, the front end of a foot slide frame (47) that slides together with the foot unit (40).

  The fixing means (90) includes a knob (92) on the base (11) and a substantially L-shaped bent tip that rotates integrally with the knob (92) and a receiving portion (96) described later. It has a stopper (94) to be fitted, and further has a receiving part (96) projecting from the first slide rail (52) etc. that does not move in the extending direction of the leg unit (30). When the knob (92) is rotated in the direction of arrow E from the state of FIG. 17, the stopper (94) is fitted into the receiving part (96), and the swinging of the leg unit (30) is prevented (FIG. 18). ). Further, by rotating the knob (92) in the reverse direction (arrow F direction) from the state of FIG. 18, the stopper (94) is detached from the receiving part (96), and the leg unit (30) can swing. (FIG. 17). Of course, the fixing means (90) is not limited to this configuration.

  When the chair-type massage machine (10) is moved, first, the foot massage unit (20) is rotated upward from the state shown in FIG. 40) and the leg unit (30) are moved in the extending direction with the soles or the like (see FIGS. 4, 7, and 15), and the foot unit (40) and the leg unit are moved by the lock mechanism (70). Fix the extension movement of (30).

Next, when the chair type massage machine (10) is gripped by the backrest (14) and tilted backward, the foot massage unit (20) is rotated downward (in the direction of arrow C in FIG. 15) by its own weight. As shown in FIG. 16, the leg unit (30) contacts or approaches the base (11). In this state, the knob part (92) is rotated as shown in FIGS. 17 to 18, and the stopper (94) is engaged with the receiving part (96). It becomes impossible to swing with respect to (11).
Therefore, when the hand holding the backrest (14) is released, the chair-type massage machine (10) has the main roller (80) and the sub-roller (82) as shown in FIG. Thus, the heavy chair type massage machine (10) can be freely moved in a stable state by these four front, rear, left and right rollers (80) (80) (82) (82).

  After the chair type massage machine (10) is moved, the locking mechanism (70) is operated to fix the leg unit (30) and the foot unit (40) in the extending direction in order to return to the state shown in FIG. Then, the knob (92) may be rotated to release the stopper (94) from the receiving part (96) as shown in FIG. Thereby, the foot massage unit (20) can swing with respect to the base (11).

  INDUSTRIAL APPLICABILITY The present invention is useful as a chair-type massage machine equipped with a foot massage unit that can move a leg unit and a foot unit to a desired position of a user and is excellent in stability even when extended.
