Description

  The present invention relates to a massage machine such as a massage chair, and more particularly to an ottoman that is attached in front of a seat portion of a seat body and massages the lower leg, foot, and sole of a user.

  In a typical chair type massage machine, a treatment body called a kneading ball or a treatment element provided on the back portion of the seat body is moved in the front-rear direction and the up-down direction to perform a hitting operation and a kneading operation for the user. It is common. There is also a commercialized massage machine that further includes an ottoman in front of the seat portion of the seat body, and a treatment body such as an airbag provided on the ottoman massages the lower leg of the user to be placed on the ottoman. Conventionally, as a chair type massage machine with an ottoman, a thing as described in Unexamined-Japanese-Patent No. 2010-75421 (patent document 1) is known, for example.

  The massage machine described in Patent Literature 1 can store the ottoman below the seat in a storage state that is not used, and pulls the ottoman forward from the seat during use. The ottoman has a lower leg holding part and a foot tip holding part. In the stowed state, the lower leg holding part is in a posture with the lower leg holding surface facing downward, and the foot tip holding part is in a posture with the foot tip holding surface facing backward. When the entire ottoman moves forward, the toe holding part slides forward as it is, while the crus holding part is restricted to slide forward and the front end part is moved upward at a predetermined position in the front-rear direction. Rotate upright to lift up, and take a posture with the lower leg support surface facing forward. The toe holding portion rotates so that the toe side is tilted forward, and the toe holding surface is oriented upward. In this way, the ottoman is put into use.

JP 2010-75421 A

  In spite of the large and small physique of the user, the conventional massage machine cannot finely adjust the position of the ottoman in use. For this reason, the problem described below occurs.

  First, in order to receive suitable treatment, the user's lower leg needs to be in close contact with the lower leg holding surface of the lower leg holding part, but the ottoman's lower leg holding part cannot be adjusted in the front-rear direction. The distance from the buttocks of the user sitting on the seat body to the popliteum varies depending on the physique of the user, and when the user is seated and pulls out the ottoman below the seat surface, The lower leg holding surface of the lower leg holding part is not necessarily in close contact with the lower leg of the user. For example, in the case of a large user, the lower leg is separated further forward than the lower leg holding part. This forces the user to sit back.

  Secondly, the angle of the ottoman's lower leg holding part cannot be adjusted. For this reason, it is impossible to adjust the vertical height from the seat surface of the seat body to the ottoman's lower leg holding part. The distance from the ankle to the popliteal of the user sitting on the seat body, in other words, the length and size of the lower leg varies depending on the physique of the user, and the lower leg holding part of the ottoman is the lower leg of the user. Is not necessarily held appropriately. For example, in the case of a large user, when the user's foot is placed on the ottoman's toe holding surface, the popliteal surface of the user will float above the lower part of the ottoman's leg.

  Thirdly, the ottoman's toe holding portion cannot be adjusted vertically. Even if the part of the lower leg you want to receive massage may vary from person to person, the height in the vertical direction from the massage part provided on the lower leg holder to the toe holding surface of the toe holder Can not be adjusted to the desired height. Further, if the user is a small person, the foot of the user does not reach the ottoman's foot holding surface.

  An object of this invention is to provide the massage machine provided with the ottoman which can respond flexibly to a to-be-treated person's physique in view of the above-mentioned situation.

For this purpose, the massage machine according to the present invention comprises a seat body and an ottoman that is provided in front of the seat body and massages the lower leg of the user seated on the seat body.

  According to the present invention, the displacement member can be finely adjusted steplessly in the front-rear direction, and the front-rear direction positions of the crus holding part and the sole support part can be set to desired positions. Further, the rotation angle of the lower leg holding part can be finely adjusted steplessly, and the lower leg holding part and the sole support part can be set to desired angles. Furthermore, the sole support part can be finely adjusted stepwise in the vertical direction, and the distance between the crus holding part and the sole support part can be set to a desired distance. Therefore, it can adapt to the user who has various physiques. The displacement member is not particularly limited as long as it is displaced in the front-rear direction. For example, the displacement member may be displaced in the front-rear direction with respect to the seat body by a telescopic rod, or may be displaced in the front-rear direction with respect to the seat body by a rack and pinion, or may be provided in a rail or a long hole. You may displace to the front-back direction with respect to a seat main body by sliding along.

The lower leg holding part extends in the vertical direction along the lower leg of the user. And the pillar member lower thigh holding part are provided is pivotally connected to the front end of the displacement member through a connecting shaft which is the lower end portion extending in the right-and-left direction, in the longitudinal direction of the upper end portion to the connecting axis Displaceable .

  As an embodiment, the present invention may have a fixing screw or the like for stopping the rotation of the lower leg holding portion. In another embodiment, the crus holding unit is configured so that the user's preferred angle and position are determined by the force applied by the user's lower leg to the crus holding unit or the force applied by the user's foot to the sole support unit. Retained.

  As an embodiment, the present invention may have a fixing screw or the like for stopping the displacement of the sole support portion. As another embodiment, the ottoman may further include a sole support portion urging member that urges the sole support portion from below to above. According to this embodiment, the sole support portion can be held at a position where the urging force of the sole support portion urging member balances the force with which the sole steps on the sole support portion and the weight of the foot. .

  Since the sole support part is supported by the lower leg holding part, the weight of the foot is received by the lower leg holding part. As a preferred embodiment, the sole support part can be lowered to the installation surface on which the seat body is installed. According to this embodiment, even if the user puts the entire weight on the sole support portion, the sole support portion 51 can be lowered to contact the installation surface.

  The massage machine 10 includes a seat body 11 on which a user is seated, and an ottoman 21 provided on the seat body 11 to massage the lower leg of the user. The ottoman 21 is moved further forward than the seat body 11 during use shown in FIGS. In such a use state, the ottoman 21 holds the lower leg of the user who sits on the seat body 11. On the other hand, when not in use as shown in FIGS. 1 and 3, the ottoman 21 is housed inside the seat body 11. In such a storage state, the ottoman 21 does not exist outside the seat body 11, and the massage machine 10 is reduced in size.

  The seat body 11 includes a seat portion 13 in which the seat surface 12 is formed and a backrest portion 15 in which the backrest surface 14 is formed. The seat surface 12 supports the user's buttocks and thighs. The backrest surface 14 supports the back of the user.

  The ottoman 21 is an assembly for massaging the lower leg of the user seated on the seat body 11, and includes a slide frame 31, a lower leg holding part 41, and a foot support part 51 as shown in FIG. The crus holding part 41 has forward and flat crus holding surfaces 42l and 42r extending in the vertical direction on the left and right. Further, the lower leg holding portion 41 is formed with side walls 44l and 44r that rise forward from both left and right edges, and a partition wall 45 that rises forward from between the lower leg holding surfaces 42l and 42r. Then, these side wall 44l, lower leg holding surface 42l, partition wall 45, lower leg holding surface 42r, and side wall 44r, the lower leg holding portion 41 has an E-shape when viewed from above as shown in FIG. Is done. Among these, the side wall 44l, the lower leg holding surface 42l, and the partition wall 45 hold the left lower leg of the user. The partition wall 45, the lower leg holding surface 42r, and the side wall 44r hold the right lower leg of the user. In the following, when there is no particular need to distinguish between left and right, they may be simply referred to as a crus holding surface 42 and a side wall 44.

  A treatment body such as an airbag or a vibration source is disposed on the inner wall surfaces of the side walls 44l and 44r, the lower leg holding surfaces 42l and 42r, and the partition wall 45, and the user is driven by driving the treatment body. Massage the lower leg. Therefore, in order to receive a sufficient massage, the lower leg must be in close contact with the lower leg holding surfaces 42l and 42r.

  The sole support unit 51 has left and right flat foot support surfaces 52l and 52r on which the foot of the user is placed. Further, the sole support portion 51 is formed with side walls 54l and 54r that rise upward from both left and right edges, and a partition wall 55 that rises upward from between the sole support surfaces 52l and 52r. The sole support portion 51 is attached to the lower side of the crus holding portion 41 via a pair of right and left rods 53, 53 that can be expanded and contracted, and can be displaced in the vertical direction. In the following, when there is no particular need to distinguish between left and right, they may be simply referred to as a sole support surface 52 and a side wall 54.

  A notch having the same shape as the side wall 54l is formed in the lower portion of the side wall 44l. Further, a notch having the same shape as the partition wall 55 is formed in the lower part of the partition wall 45. Further, a notch having the same shape as the side wall 54r is formed in the lower portion of the side wall 44r. Thereby, when the rod 53 is shortened, the side wall 54 fits in the lower part of the side wall 44, and the partition wall 55 fits in the lower part of the partition wall 45, so that the ottoman 21 can be reduced to a clean and compact shape.

  The lateral width of the side wall 54l is the same as the lateral width of the side wall 44l, the lateral width of the partition wall 55 is the same as the lateral width of the partition wall 45, and the lateral width of the side wall 54r is the same as the lateral width of the side wall 44r. Thereby, when the rod 53 is shortened, the crus holding part 41 and the sole support part 51 can be integrated into one continuous shape.

  The slide frame 31 is a displacement member that is connected to the lower portion of the seat body 11 so as to be displaceable in the front-rear direction. The slide frame 31 extends in the front-rear direction, and its rear end region is slidably connected to the seat body 11 in the front-rear direction. Is connected to the lower end of the crus holding part 41 via the connecting shaft 43. The connecting shaft 43 is an axis extending in the left-right direction. Therefore, the upper leg portion of the lower leg holding portion 41 is rotatable in the front-rear direction with the lower end portion as the center of rotation.

  As an action of the slide frame 31, the ottoman 21 is movable between the rear storage state and the front use state, and the ottoman 21 is positioned in the front-rear direction in the use state as indicated by an arrow A in FIG. It can be finely adjusted steplessly.

  As an action of the connecting shaft 43, the crus holding part 41 is tilted upward in the retracted state and stands forward in the use state, and the crus holding part 41 has an inclination angle in the use state as shown by an arrow B in FIG. It can be finely adjusted steplessly. In particular, the connecting shaft 43 and the slide frame 31 can be combined to adjust the inclination angle while adjusting the longitudinal positions of the crus holding surfaces 42l and 42r. Therefore, regardless of the size of the user's physique or the length (thigh length) from the user's buttocks to the popliteal area, the user should keep the lower leg in close contact with the lower leg holding surfaces 42l and 42r. Can do. As a result, the user can suitably receive a lower leg massage without having to sit down on the seating surface 14.

  As an action of the rod 53, the sole support 51 is drawn to the crus support 41 in the stored state, and the vertical position can be finely adjusted steplessly as shown by an arrow C in FIG. Strictly speaking, when the crus holding part 41 tilts backward, the position from the lower front to the rear upper can be finely adjusted steplessly. That is, the distance from the lower leg holding part 41 to the sole support part 51 can be adjusted. Therefore, the seat surface height from the installation surface G on which the massage machine 10 is placed to the front end of the seat surface 12, the size of the user's physique, the distance from the user's popliteum to the ankle (the length of the lower leg) Regardless of the length of (), the region of the lower leg where treatment is desired can be matched with the lower leg holder 41. As a result, the lower leg can be effectively massaged, and the needs of the user can be satisfied at a high level.

  Adjustment of the front-rear direction and the inclination angle of the crus holding part 41 and the sole support part 51 is performed by the user stepping on the sole support surfaces 52l and 52r with the soles, bending the knees and bending the knees with the crus holding surfaces 42l and 42r. This is done by depressing and moving it to the desired position and angle. Although described in detail later, the ottoman 21 has a sole support portion urging member that urges the sole support portion 51 from below to above. The sole support portion 51 is positioned such that the sum of the stepping force of the user and the weight of the lower leg balances the urging force of the sole support portion urging member.

  As described above, according to the present embodiment, the arrows A, B, and C shown in FIG. 5 can be adjusted at the same time. Therefore, the strength and direction of the force applied to the ottoman 21 by the lower leg and foot of the user are appropriately determined. By changing the amount, the lower leg holding part 41 can be finely adjusted steplessly to the position and inclination angle desired by the user. Similarly, the sole support 51 can be finely adjusted steplessly to the front / rear direction position, the vertical direction position, and the inclination angle desired by the user.

  Further, in this embodiment, when the user puts weight on the sole support surfaces 52l and 52r, the sole support portion 51 can be lowered to contact the installation surface G. Accordingly, the weight of the user can be released to the installation surface G, and the ottoman 21 can be prevented from being damaged by the weight of the user having a large physique.

  A supplementary description will be given of the procedure for changing the ottoman 21 from the stored state to the used state.

  The ottoman 21 is located below the seating surface front end 12a and below the seating surface 12 and below the seating surface 12, with the lower leg holding surface 42 facing upward and the sole support surface 52 facing backward. It is stored in. When the user sitting on the seat body 11 operates the operation lever described later while the ottoman 21 is stored (FIG. 3), a part of the ottoman 21 moves the seat surface front end 12a as shown in FIG. Go ahead and move forward. Next, when the user pushes the sole support part 51 forward with a toe or heel, the ottoman 21 moves further forward. When the user applies a force to the sole support surface 52 in order to bring the sole support portion 51 to a desired position and inclination angle, the lower leg support portion 41 is turned upright as shown in FIG. The sole support part 51 moves downward from the crus holding part 41, and the ottoman 21 is put into use.

  On the other hand, when storing the ottoman 21 in use, the user steps on the upper end portion of the crus holding part 41 with the soles of the foot and falls backwards so that the crus holding surface 42 faces upward and supports the soles. Face 52 is facing backwards. And it is good to push the sole support part 51 back. As a result, the rod 53 is shortened and the slide frame 31 is moved rearward, and the ottoman 21 moves rearward from the use state shown in FIG. 5 to the storage state shown in FIG. 3 through the intermediate state shown in FIG. To do.

  In addition, the foot support portion 51 closes the front end opening of the space below the seat surface below the seat surface 12 as shown in FIG. Thereby, the ottoman 21 is made inconspicuous and is neatly cleaned up.

  The operation lever 63 has an L shape bent at a right angle in the middle, and one end of the operation lever 63 is rotatably attached to the seat surface frame 12f via a rotation shaft 63o. The operation lever 63 extends from one end to the front, and is provided with a rotation connection point 63j. The operation lever 63 extends further forward from the rotation connection point 63j, changes its direction at a right angle and extends upward, and reaches the other end. . A straight portion extending in the vertical direction, which is the side including the other end, constitutes the grip portion. When the user rotates the operation lever 63 so as to tilt backward, the rotation connection point 63j moves upward. As a result, the wire 67 moves in the tube 68 and pulls up the lock member 62 from the lock position to the release position against the biasing force of the torsion spring 65s.

  When the user releases the operation lever 63, the lock member 62 is returned to the locked position by the biasing force of the torsion spring 65s, and the operation lever 63 is also returned to the original position as shown in FIG. To do.

  The lock member 62 is shaped to have a thin front end. As a result, when the slide frame 31 moves from the front to the rear and the short frame 33 comes into contact with the front end of the lock member 62, the slide frame 31 sinks under the lock member 62 while pushing the front end of the lock member 62 upward. As a result, the short frame 33 can be engaged with the hook portion 64, and the slide frame 31 is locked again so that it cannot move in the front-rear direction.

Referring to FIG. 7, a pair of left and right springs 69 are attached to pedestal 61b. The spring 69 receives the rear end of the longitudinal frame 32 and prevents the longitudinal frame 32 from coming out rearward from the rail member 18. In the housed state, the spring 69 abuts against the rear end of the longitudinal frame 32 and is pushed toward the pedestal 61b to be compressed and deformed. For this reason, when the lock member 62 is pulled up to the release position, the compressive force stored in the spring 69 is released, and the spring 69 biases the longitudinal frame 32 forward. 8 showing the lock position and FIG. 9 showing the release position, it can be seen that the frame assembly 22 including the slide frame 31 advances forward in the release position. The frame assembly 22 can move further forward as shown in FIG. As a modification (not shown), the spring 69 may not be provided, and the rear end of the longitudinal frame 32 may come into contact with the pedestal 61b to prevent the longitudinal frame 32 from coming out backward.

  The rotation operation of the lower leg holding part 41 will be described.

  10-12 is explanatory drawing which looked at the frame assembly 22 of the ottoman 21 from the right direction. 10 shows a state in which the column members 44c and the side wall plates 44f included in the crus holding part 41 are in a horizontal posture of 0 °, and FIG. 11 shows a state in which the column members 44c and the side wall plates 44f are in an inclined posture. FIG. 12 shows a state in which the column member 44c, the side wall plate 44f and the like are in a 90 ° vertical posture. It should be noted that FIGS. 10 to 12 do not necessarily accurately represent the positional relationship of each member in the left-right direction in order to facilitate understanding of the positional relationship in the front-rear direction and the vertical direction of each member.

  Referring to FIG. 10, the guide member 47 is connected to a short frame 33 that connects the front ends of the long frame 32 via a rotation shaft 49, with the rotation shaft 49 as a base end and the long hole 47 s side. It turns as a free end. A torsion spring 49t is incorporated in the rotation shaft 49. One end of the torsion spring 49t contacts the short frame 33, and the other end of the torsion spring 49t contacts the guide member 47. Then, the guide member 47 is urged with a light force in a direction to stand forward. With the guide member 47 tilted backward and the free end of the guide member 47 in the most rearward position, the column member 44c is placed in a horizontal posture. As a result, the lower leg holding surface 42 of the lower leg holding part 41 is leveled upward in the stored state. At this time, the protrusion 48p of the bracket 48 penetrating the long hole 47s is located on the most proximal side in the long hole 47s. At this time, the frame body 56 is set in a vertical posture, and the sole support surface 52 formed along the frame body 56 is set in a backward posture.

  When the user kicks the foot support 51 including the frame 56 forward with his / her foot, the guide member 47 is turned upright and the column member 44c is inclined as shown in FIG. As a result, the crus holding surface 42 of the crus holder 41 in the state of use is inclined upward and forward according to the user's preference (FIG. 2). At this time, the protrusion 48p of the bracket 48 penetrating the long hole 47s is located in the central region in the longitudinal direction of the long hole 47s (FIG. 11).

  The ottoman 21 has a torsion spring 49t as a crus holding part urging member that urges the crus holding part 41 tilted rearward to stand up around the connecting shaft 43. The torsion spring 49t reduces the force by which the user kicks the frame body 56 in the vertical posture with his / her foot. Therefore, the user can easily raise the lower leg holding portion 41 in the horizontal posture. However, if the column member 44c rises even slightly, the guide member 47 moves away from the torsion spring 49t (FIG. 11). For this reason, the column member 44c is set to a preferred inclination angle by the force of the lower leg and foot of the user L in an inclined posture.

  In addition, since the moment due to the torsional force of the torsion spring 49t is weaker than the moment around the connecting shaft 43 due to the own weight of the lower leg holding portion 41, more precisely, the lower leg holding portion 41 and the sole support portion 51, If the user does not kick the sole support 51 including the frame 56 forward with his / her foot, the frame 56 remains in the vertical posture shown in FIG. 10 and the sole support formed along the frame 56 is provided. Surface 51 remains facing backwards.

  In addition, as a modification (not shown), the torsion spring 49t may be omitted, and the crus holding part 41 in the horizontal state may be turned upright only by the force of the foot of the user.

  When the user L steps on the sole support 51 including the frame body 56 with his / her foot, the guide member 47 rotates so as to rise further than the posture shown in FIG. 11, and the column member as shown in FIG. 44c is in a vertical posture. At this time, the projection 48p of the bracket 48 penetrating the long hole 47s is located closest to the free end in the long hole 47s.

  In this way, the guide member 47 guides the protrusion 48p along the long hole 47s, thereby restricting the inclination angle of the lower leg holding surface 42 to a region from a horizontal angle of 0 ° to a vertical angle of 90 ° (FIGS. 10 to 10). 12).

  The up / down operation of the sole support 51 will be described.

  13 and 14 are explanatory views of the frame assembly 22 of the ottoman 21 as viewed from the right. FIG. 13 illustrates a state in which the frame body 56 included in the sole support portion 51 is most attracted to the side wall plate 44 f included in the crus holding portion 41. FIG. 14 shows a state in which the frame body 56 is farthest from the side wall plate 44f. It should be noted that FIGS. 13 and 14 do not necessarily accurately represent the positional relationship of each member in the left-right direction in order to facilitate understanding of the positional relationship of each member in the front-rear direction and the vertical direction. Further, when the crus holding part 41 is in a vertical posture, the sole support part 51 moves in the vertical direction. Therefore, the direction in which the sole support part 51 moves is referred to as the vertical direction for convenience. It should be noted that the foot support 51 moves in the front-rear direction when it is done.

  The rod 53 is an elongated hollow cylinder, and the upper end 53e side of the rod 53 is slidably attached to the side wall plate 44f. The lower end of the rod 53 is fixed to the frame body 56. Specifically, the upper end 53e of the rod 53 to the central region is sandwiched between two pairs of rollers 57 provided on the side wall plate 44f. One pair of rollers 57 are provided on the upper side and the lower side of the side wall plate 44f, and the rod 53 is drawn downward or pulled upward by the rotation of the two pairs of rollers 57. Then, the rod 53 is extended downward to move the frame 56 downward. Alternatively, the rod 53 is pulled upward to move the frame 56 upward. The upper end 53e of the rod 53 has a larger diameter than the distance between the pair of rollers 57, 57, and the upper end 53e does not extend downward beyond the pair of rollers 57. Therefore, the rod 53 is prevented from being detached from the roller 57.

A spring 58 is stretched inside the pipe- shaped rod 53. The lower end of the spring 58 is locked to the lower end of the rod 53, the upper end of the spring 58 is upwardly engaged with the locking projection 53u provided on the side walls 44f than the roller 57, the inner space of the spring 58 the rod 53 Hold on. When the rod 53 is drawn downward, the spring 58 is pulled to urge the frame 56 upward. Thus, the spring 58 is a sole support portion urging member that urges the sole support portion 51 upward, and the sole support portion 51 is urged toward the crus holding portion 41.

  In other words, when the foot of the user L steps down the frame body 56, the angle and height of the frame body 56 change corresponding to the stepping force as shown in FIG. Then, when the user sitting on the seat 12 stands up with the feet of the user L placed on the frame 56 (more precisely, the sole holding surface 52), the frame 56 is moved as shown in FIG. It descends to the installation surface G and is positioned along the installation surface G.
