  First, the basic configuration and behavior of the example massage machine shown in FIGS. 1 to 4 will be described, and then the specific structure of the characteristic portion shown in FIGS. 5 to 10 will be described in detail.

  The example massage machine shown in FIGS. 1 to 4 is of a chair type (sofa type), a seat part 1 on which a user (not shown) sits, and a backrest part on which a user in a sitting position leans back. 3 and left and right armrests 4 on which a user in a sitting position can place the elbow tip. Moreover, the ottoman 2 which hold | maintains the user's right and left leg part in the attitude | position which seated on the seat part 1 is provided. The directions such as front and rear and left and right used in the text are based on the direction viewed from the user in the sitting posture.

  An example of a massage machine includes treatment means for applying massage to a user in a sitting position. Although the treatment means is not shown in the figure, for example, a treatment structure that massages the shoulder, back, waist, etc. of the user by driving a treatment element disposed on the backrest 3 or an airbag disposed on the seat 1 For example, a structure in which a massage is applied to the user's buttocks and a structure in which an airbag or the like disposed in the ottoman 2 is driven to massage the legs of the user is preferably used. Of course, you may provide the treatment means of another structure.

  In the present invention, the ottoman 2 has a crus holding part A having a crus holding surface 5 for holding a crus part of a user's leg, and a toe holding surface 6 for holding a toe part. The toe holding part B is provided separately. Here, the “lower leg part” means the part from the knee to the ankle, and the “foot tip part” means the part from the ankle to the tip.

  As shown in FIG. 4, the crus holding part A is provided with a pair of crus holding surfaces 5 on the left and right sides where the back side (calf) of the lower leg part hits. In the crus holding part A, a partition wall 7 is erected from a portion sandwiched between the left and right crus holding surfaces 5, and outer walls 8 are erected from outer ends of the left and right crus holding surfaces 5.

  Both the partition wall 7 and the outer wall 8 are erected in the direction facing the lower leg holding surface 5. Therefore, the crus holding surface 5 sandwiched between the partition wall 7 and the outer wall 8 has a shape like the bottom surfaces of a pair of left and right concave grooves provided in the crus holding part A. In other words, the lower leg holding part A as a whole has an outer shape in which the partition wall 7 and the outer wall 8 are erected in an E shape from the substrate portion having the lower leg holding surface 5.

  Further, in the crus holding part A, as shown in FIG. 4, a pair of left and right cutouts 10 are formed in a concave shape in a part that becomes the upper end side when used. The cutout portion 10 is provided so as to cut out the upper end sides of the left and right lower leg holding surfaces 5. By providing the notch portion 10, the upper end position of the lower leg holding surface 5 is made lower than the partition wall 7 and the outer wall 8.

  The toe holding portion B is provided with a toe holding surface 6 so that the soles of the left and right toe portions are in contact with each other, and an outer wall 9 is erected from the left and right ends of the toe holding surface 6. The outer wall 9 is erected in the direction in which the toe holding surface 6 faces, and the entire toe holding portion B has an outer shape in which the outer wall 9 is erected in a U-shape from the substrate portion having the crus holding surface 5. Yes.

  In the ottoman 2 composed of the crus holding part A and the toe holding part B having the above-described configuration, a part of the crus holding part A (the part that becomes the upper end side in use) fits between the left and right outer walls 9 of the toe holding part B. In a compacted state (hereinafter referred to as “stored state”), it is stored in the lower space of the seat portion 1.

  FIGS. 1 (a) and 2 show the ottoman 2 hidden under the seat 1 in the retracted state. FIGS. 1 (b) and 3 show the ottoman 2 in the retracted state in front. Fig. 5 shows a state where the material is pushed out by a predetermined distance d.

  As shown in FIG. 3 and the like, in the storage state, the crus holding part A is positioned in a posture in which the crus holding surface 5 faces downward (hereinafter referred to as “downward posture”), and the foottip holding part B The holding surface 6 is positioned in a rearward orientation (hereinafter referred to as “backward orientation”).

  And the front end part (part which becomes an upper end side at the time of use) of the leg support part A in this downward posture is accommodated between the left and right outer walls 9 of the toe support part B, thereby making the whole compact.

  In the stored state, the notch portion 10 of the crus holding part A is located at the front end part of the crus holding part A, and the notch part 10 of the crus holding part A is located between both outer walls 9 of the foottip holding part B. Arrangement.

  Therefore, when the ottoman 2 is pushed forward by a predetermined distance d while being in the stored state, the cutout portion 10 is exposed to the outside as shown in FIG.

  When the entire ottoman 2 is pushed further forward from the state shown in FIG. 3, the toe holding part B slides forward as it is, while the crus holding part A lifts the tip part upward. It starts to rotate (see arrow a in FIG. 1 (c)).

  The crus holding part A can rotate independently of the toe holding part B until the crus holding surface 5 is in a posture (hereinafter referred to as “maximum rotational posture”) that faces obliquely upward in the front direction. When the lower leg holding portion A reaches the maximum rotation posture, the upper end portion thereof is brought closest to the upper surface of the seat portion 1 as shown in FIG.

  When the crus holding part A is in the maximum rotational position or in the vicinity of the maximum rotating position, the left and right lower leg parts of the user are fitted into the grooves of the lower leg holding part A, and the left and right foot part are further connected to the toe holding part. Use Ottoman 2 by placing it on B.

  In addition, in the ottoman 2 of this example, not only the lower leg holding part A but also the toe holding part B can be rotated independently. The toe holding part B can be rotated so that its toe side is tilted forward (see arrow b in FIG. 1 (c)), a rearward posture with the toe holding surface 6 facing rearward, and the toe holding It is rotatable between a posture with the surface 6 facing upward (hereinafter referred to as an “upward posture”).

  In addition, since the toe side of the toe holding part B is applied with a rotational biasing force toward the seat part 1 with respect to the toe holding part B, the toe holding part B is Maintained backwards posture.

  When the ottoman 2 is stored, the procedure is reversed from the case where the ottoman 2 is pulled out from below the seat portion 1.

  That is, when the crus holding part A and the toe holding part B are slid rearward from the use state shown in FIG. 1 (c) or FIG. 4, the crus holding part that was in the maximum rotational position or in the vicinity of the maximum rotational position. A starts to rotate so that the tip part is pushed forward.

  When the crus holding part A rotates to the downward posture, at this time, the crus holding part A reaches a storage state partially fitted to the toe holding part B as shown in FIG. 1 (b) and FIG. By sliding backward in the stored state, the seat 1 is stored under the seat 1.

  The basic shape and behavior of the crus holding part A and the toe holding part B forming the ottoman 2 have been described above.

  Hereinafter, the storage support mechanism 27 that supports the crus holding part A and the toe holding part B so as to perform the above-described behavior will be described in more detail with reference to FIGS.

  5 and 7 show the frame structure of the entire massage machine. The state shown in FIG. 5 is a state in which the ottoman 2 is stored in the retracted state under the seat portion 1, and the state shown in FIG. 7 is a state in which the ottoman 2 is slid the most forward and the crus holding portion A is in the maximum rotation posture. It is in the state rotated to.

  As shown in the figure, the seat frame 11 constituting the seat portion 1 has support legs 12 extending downward from the front, rear, left and right thereof. Further, a back frame 13 constituting the back portion 3 is connected to the seat frame 11.

  Then, as the storage support mechanism 27 that supports the crus holding part A and the toe holding part B, the slide frame 14 that supports the entire ottoman 2 is connected to the support leg 12 so as to be slidable back and forth. A crus holding part A and a toe holding part B are connected to the slide frame 14 so as to be rotatable about the left and right axis.

  Therefore, both the crus holding part A and the toe holding part B are slidable back and forth with respect to the seat part 1 and are rotatable independently of each other. Further, the storage support mechanism 27 includes a rotation driving means 22 (described later) that rotates the crus holding part A in conjunction with the forward sliding of the crus holding part A and the toe holding part B.

  A mechanism for slidably connecting the slide frame 14 to the seat portion 1 includes a rail member 15 and a roller member 16 as shown in FIG. The rail member 15 is fixed to the support leg 12 so as to form a pair on the left and right, and the roller member 16 is provided on each of the left and right sides of the slide frame 14. Each roller member 16 is disposed in a corresponding rail member 15 so as to be freely rollable.

  The crus holding frame 17 constituting the crus holding part A is connected to a pair of left and right support pillars 18 extending upward from the front portion of the slide frame 14 so as to be rotatable about a rotation shaft 19.

  The rotary shaft 19 for the crus holding part A is provided at the upper end of the support column 18 so that the left-right direction is the axial direction. Further, the foot support frame 26 constituting the foot support section B is connected to a pair of left and right support columns 20 extending forward from the front end portion of the slide frame 14 so as to be rotatable about a rotation shaft 21. The

  The rotation shaft 21 for the foot tip holding portion B is provided at the front end portion of the support column 20 so that the horizontal direction is the axial direction. In addition, the support pillar 18 for the lower leg holding part A and the support pillar 20 for the foot tip holding part B are provided so that the support pillar 20 for the foot tip holding part B is positioned forward.

  Therefore, the rotation shaft 21 for the foot tip holding portion B is positioned obliquely downward and forward with respect to the rotation shaft 19 for the lower leg holding portion A.

  The lower leg holding part A has its center of gravity positioned so as to maintain a downward posture particularly when no external force is applied. The rotation driving means 22 for rotating the crus holding part A from the downward posture is a connecting member 23 arranged so as to connect the seat frame 11 and the crus holding frame 17. The connecting member 23 is made of a string-like member having flexibility.

  The part where one end side of the connecting member 23 is fixed to the crus holding frame 17 is a part which is in front of the rotation shaft 19 in the crus holding frame 17 when the crus holding part A is in the downward posture (FIG. 6). reference).

  Further, the portion where one end side of the connecting member 23 is fixed to the lower leg holding frame 17 is provided so that the other end side of the connecting member 23 is positioned obliquely downward in front of the portion fixed to the seat frame 11.

  When the ottoman 2 is stored below the seat portion 1, the connecting member 23 is in a bent state, and when the slide frame 14 is pushed forward so that the entire ottoman 2 protrudes by a predetermined distance d, the connecting member 23. Is stretched in the front-rear direction.

  When the slide frame 14 is further pushed out here, the tension acting on the connecting member 23 acts to rotate the crus holding frame 17 (that is, the entire crus holding part A). When the slide frame 14 is pushed out to the front, the crus holding part A reaches the maximum rotation posture (see FIGS. 7 and 8).

  A torsion coil spring 25 is disposed on the rotating shaft 21 as a rotation urging means 24 that applies a rotation urging force to the foot tip holding part B in the foot tip holding part B. The torsion coil spring 25 applies a rotational biasing force to the toe holding frame 26 (that is, the entire toe holding portion B) in a direction in which the toe side is close to the seat portion 1.

  Therefore, when the toe holding surface 6 of the toe holding part B is pushed out by the sole, the toe holding part B rotates so that the toe side is tilted forward, and if the sole is pulled back, it is accompanied accordingly. The toe holding part B returns to raise the toe side.

  Furthermore, the massage machine of an example stores the lock mechanism 30 for temporarily fixing the ottoman 2 in the storage position below the seat portion 1, the release mechanism 31 for releasing the temporary fixing by the lock mechanism 30, and the ottoman 2. And an urging means 32 for pushing forward a predetermined distance d from the position.

  As shown in FIG. 10, the lock mechanism 30 includes a stopper 33 provided on the rail member 15 side connected to the seat frame 11 and a stopper receiver 34 fixed to the slide frame 14 side connected to the ottoman 2. .

  The stopper 33 is attached to the rail member 15 via the swing arm 35, and between the lower position where it hits the stopper receiver 34 and the upper position where it does not hit the stopper receiver 34 due to the swing of the swing arm 35. , Switchable. The swing arm 35 is biased by a torsion coil spring so as to hold the stopper 33 in the lower position.

  The release mechanism 31 includes the swing arm 35, a lever 36 installed on the seat frame 11, and a wire rod 37 that connects the lever 36 and the swing arm 35. When the operation portion 38 of the lever 36 is pulled upward, the swing arm 35 swings in a predetermined direction via the wire rod 37 and moves the stopper 33 to an upper position where it does not come into contact with the stopper receiver 34.

  The urging means 32 includes a tension coil spring 39 interposed between the rail member 15 and the slide frame 14. The tension coil spring 39 applies a forward biasing force to the slide frame 14 when the slide frame 14 is in the storage position below the seat 1.

  When the slide frame 14 moves forward by the predetermined distance d, the urging force applied by the tension coil spring 39 does not significantly affect the forward movement of the slide frame 14.

  When the ottoman 2 is in the storage position, the stopper 33 is engaged with the stopper receiver 34 to prohibit the movement of the slide frame 14 by the urging of the tension coil spring 39.

  When the ottoman 2 is used, the lever 36 is operated to lift the stopper 33 and release the engagement with the stopper receiver 34. As a result of this release, the entire ottoman 2 protrudes forward by a predetermined distance d due to the urging of the tension coil spring 39.

  According to the massage machine of the present example configured as described above, the ottoman 2 can be set and used as described below, and can be stored easily and compactly after use.

  First, in use, the user sits on the seat portion 1 of the massage machine in a state where the ottoman 2 is housed. From the side of the seat 1, a pulling member 40 (see FIG. 2 and the like) connected to the operating portion 38 of the lever 36 is exposed, and the temporary fixing by the stopper 33 is released by pulling the pulling member 40 upward. Then, the entire ottoman 2 is pushed forward by a predetermined distance d by the urging force of the tension coil spring 39.

  At this time, the notch 10 provided at the tip of the crus holding part A is exposed as shown in FIG. The user inserts the toe portion from above through the cutout portions 10 on both the left and right sides, and presses the sole of the inserted toe portion against the toe holding surface 6 of the toe holding portion B. At this time, the toe holding portion B rotates forward by being pushed by the foot (see arrow b in FIG. 1 (c)) and is displaced so as to fit the angle of the user's ankle.

  Here, when the user pushes the soles forward as they are, both the lower leg holding part A and the toe holding part B move forward through the slide frame 14. The lower leg holding part A is set by rotating the tip part by pulling the tip part to the seat part 1 side by the connecting member 23 from the middle and lifting the tip part upward (FIG. 1 (c ) (See arrow a).

  Since the crus holding part A is set by rotating from below so as to bypass the front end part of the seat part 1, it does not hit the user's leg part and does not require a large space, and can be used smoothly. Set.

  The concave cutout portion 10 provided in the crus holding part A is positioned on the upper end side of the crus holding part A in use. The cutout portion 10 prevents the user's calf portion from hitting the lower leg holding portion A and causing discomfort.

  Then, the user sets the crus holding part A of the ottoman 2 as shown in FIG. 4 and rotates the toe holding part B from the state shown in FIG. 4 to an angle that fits the sole of the foot. The leg can be massaged by appropriate treatment means such as an airbag disposed on the lower leg holding part A or the toe holding part B.

  At this time, since the posture and position of the crus holding part A and the toe holding part B can be easily changed according to the body shape of the user, a good massage is provided regardless of the body shape of the user.

  For example, when the user is small, the toe holding part B is not pushed out to the forefront, and the crus holding part A that rotates in conjunction with the pushing out of the toe holding part B is also applied. It is not rotated up to the maximum rotation posture.

  That is, the toe holding surface 6 of the toe holding portion B is relatively close to the seat portion 1, and the crus holding surface 5 of the crus holding portion A is held at an angle that does not largely tilt backward. Therefore, it fits well even for small users.

  On the other hand, when the user is large, the crus holding part A can be rotated to the maximum rotation posture by pushing the toe holding part B forward as far as possible.

  That is, the toe holding surface 6 of the toe holding unit B can be positioned away from the seat portion 1, and the crus holding surface 5 of the crus holding unit A can be held at the angle that is tilted backward most. Therefore, it fits well even for large users.

  Even when the ottoman 2 is used and stored, the user can easily store the ottoman 2 below the seat 1 by operating only the legs.

  Specifically, the user first removes the sole from the toe holding surface 6 of the toe holding unit B, and returns the toe holding unit B to a backward posture. Here, the user presses the heel side of his / her leg against the front surface of the foot-holding portion B in the backward posture (that is, a flat surface formed on the side opposite to the foot-holding surface 6) Push the foot tip holding part B backward.

  Then, both the slide frame 14 and the lower leg holding part A are pushed backward. At this time, when the forced rotation by the connecting member 23 is released, the crus holding part A rotates by its own weight and returns to the downward posture, and the entire ottoman 2 returns to the storage state as shown in FIG.

  Further, when the foot support part B is pushed backward at the heel part against the urging force of the tension coil spring 39, the stopper 33 once rides on the stopper receiver 34 provided on the slide frame 14 side and then stops. And the entire ottoman 2 is temporarily fixed at the storage position below the seat 1.

  The ottoman 2 temporarily fixed below the seat portion 1 has the foot tip holding portion B positioned so as to cover the front of the lower leg holding portion A, and only the flat front portion of the foot tip holding portion B is visible from the front. It becomes possible. Therefore, the design of the entire massage machine is well maintained.

  FIGS. 11 and 12 show other examples of the stopper 33 and the stopper receiver 34. The engagement surface of the stopper 33 with the stopper receiver 34 is such that the distance from the rotating shaft 350 of the swing arm 35 provided with the stopper 33 at the tip is different between the upper end side and the lower end side, as shown in FIG. The distance Rb on the lower end side is longer than the distance Ra.

  The engaging surface of the stopper receiver 34 with the stopper 33 is in contact with the stopper 33 on the upper side.

  Therefore, when the engagement is released by rotating the swing lever 35 from the engaged state between the stopper 33 and the stopper receiver 34 shown in FIG. 11 and pulling up the stopper 33, as shown in FIG. 12 (b). Further, the stopper 33 once pushes the stopper receiver 34 back to the rear side by the difference (Rb−Ra) between the distances Ra and Rb.

  This movement is caused by the urging force of the tension coil spring 39 by eliminating the “twist” between the slide frame 14 and the rail member 15 that slidably supports the slide frame 14 back and forth. The slide frame 14 and the ottoman 2 are smoothly moved forward.

  Further, if the slide frame 14 is not retracted against the tension coil spring 39, the engagement between the stopper 33 and the stopper receiver 34 is not released. For this reason, the reliability of the lock mechanism 30 becomes high, and the ottoman 2 will not accidentally pop out when being carried.

  In this example, the connection position between the rear end of the tension coil spring 39 and the rear end of the slide frame 14 is lowered below the connection position between the front end of the tension coil spring 39 and the rail member 15. This is also for ensuring a smooth forward / backward slide operation of the slide frame 14.

  The temporary fixing of the slide frame 14 and the ottoman 2 with respect to the front and rear slides by the stopper 33 and the stopper receiver 34 may be performed at a plurality of locations in the front and rear slide direction.

  For example, a plurality of stopper receivers 34 are provided on the slide frame 14 at intervals in the front-rear direction as shown in FIG. 13, or a plurality of engaging surfaces with the stopper 33 are provided in a stepped manner as shown in FIG. The stopper 34 receiver that is provided is used.

  In the former case, the slide amount of the ottoman 2 can be adjusted according to the time of the release operation, and in the latter case, the slide amount of the ottoman 2 can be adjusted according to the release operation amount.

  By doing so, the urging force of the tension coil spring 39 is restrained against the urging force of the ottoman 2 and the ottoman 2 is pushed back and positioned below the seat portion 1. Then you don't have to do the action of pushing it back. In addition, it is possible to suppress wobbling of the front and rear positions of the ottoman 2 when the ottoman 2 is pushed out and used.

  In the above example, the swing lever 35 provided with the stopper 33 is provided on the rail member 15 side and the stopper receiver 34 is provided on the slide frame 14 side. However, the stopper 33 is provided on the slide frame 14 side and the stopper receiver 34 is provided on the rail member 15. It may be provided on the side.

  By the way, the front end portion of the slide frame 14 provided with the ottoman 2 protrudes more forward than the front end of the rail member 15 when the ottoman 2 is used. In this state, for example, if a child gets on the toe holding part B, a large load is applied to the tip of the slide frame 14.

  In this regard, as shown in FIG. 15, it is preferable to provide a leg 140 from the front end of the slide frame 14 downward.

  The leg 140 having a small distance from the floor surface does not interfere with the front / rear slide operation because the leg 140 does not contact the floor surface when the ottoman 2 slides back and forth.

  In addition, when a large load is applied to the ottoman 2, the slide frame 14 is prevented from being damaged because the load is released to the floor surface in contact with the floor surface as shown in FIG. To prevent it.

  At this time, since the lower surface of the leg 140 has an inclination β whose front end side is slightly higher than the rear end side, a load is applied to the ottoman 2 and the chair is centered on the support leg 12 on the front side. When the lower surface of the leg 140 is in contact with the floor surface so as to rotate as a whole, the lower surface of the leg 140 is in contact with the floor surface.

  That is, since the contact area between the leg 140 and the floor surface is wide, the floor surface can be prevented from being damaged by the leg 140.

  In each example shown in FIGS. 13 to 16, the restriction of the rotation angle of the toe holding portion B in the ottoman 2 is made larger than that in the example shown first, and the toe side is located above the heel side. The toe side is not lowered below the angle (α in FIG. 15).

  This is because the force from the foot is easily applied to the toe holding part B when the toe holding part B is pushed forward with the toe with the sole on the toe holding part B. It is.

  Next, an example of a massage machine according to another embodiment of the present invention will be described with reference to FIG. Since the basic configuration is the same as the above-described configuration, only different characteristic configurations will be described in detail below.

  This massage machine is different from the previous example in that only the lower leg holding part A side of the lower leg holding part A and the toe holding part B constituting the ottoman 2 is independently rotatable.

  As shown in FIG. 11, the toe holding portion B includes a toe holding plate 50 formed so that the toe holding surface 6 side faces upward, and a front end extending upward from the front end portion of the toe holding plate 50. A side view L-shape comprising the plate 51 is used.

  A support column 18 is erected on the rear portion of the foot support plate 50, and the crus support A is rotatably supported via the support column 18. The rear end portion of the foot support plate 50 is fixed to the slide frame 14 so as not to rotate.

  When the user wants to store the ottoman 2 after using it, the user removes the sole from the toe holding surface 6 of the toe holding plate 50, presses the heel against the front surface of the front plate 51, and continues as it is. What is necessary is just to push the foot tip holding | maintenance part B back.

  When the ottoman 2 is stored, the front plate 51 of the toe holding portion B functions to cover and hide the front of the crus holding portion A in the downward posture.

  In the massage machine of another example having the above-described configuration, the ottoman 2 can be easily set and used, and can be stored easily and compactly after use, and the design is excellent.

  FIG. 18 shows a reference example. Since the basic configuration is the same as in each of the above examples, only the different characteristic configuration will be described in detail below. Of the crus holding part A and the toe holding part B constituting the ottoman 2, only the foot toe holding part B side is independently rotatable and is different from the previous example.

  As shown in the figure, the foot tip holding part B includes a foot tip holding plate 60 having a foot tip holding surface 6 and a footrest plate 61 extending in the orthogonal direction from the tip of the foot tip holding plate 60. It is L-shaped when viewed from the side.

  The foot-holding plate 60 is freely rotatable between a rearward posture shown in the figure with the foot-holding surface 6 facing backward and an upward posture with the foot-holding surface 6 facing upward. A rotational biasing force is applied in a direction in which the toe side of 60 approaches the seat 1.

  Therefore, when no external force is applied, the toe holding plate 60 is maintained in a backward posture. In this rearward posture, the footrest plate 61 of the toe holding portion B covers the upper side of the lower leg holding portion A, and in the upward posture, the footrest plate 61 of the foot toe holding portion B passes the front of the lower leg holding portion A. Located to cover.

  Therefore, the footrest plate 61 that normally covers the upper part of the lower leg holding portion A is used as a footrest, and when it is desired to use it as the ottoman 2, the foottip holding portion B may be rotated forward. When the toe holding part B rotates forward, the toe holding surface 6 is exposed in a posture facing upward, and the crus holding part A hidden by the footrest plate 61 appears.

  The lower leg holding part A is fixed to the slide frame 14 so as not to rotate. Therefore, in this reference example, the rotation driving means 22 including the connecting member 23 is not provided.

  In addition, in the massage machine of each above-mentioned example, it is good also as a structure which performs the front-and-rear slide of the slide frame 14, and rotation of the lower leg holding | maintenance part A and the foot tip holding part B electrically. Other configurations can be appropriately changed in design as long as they do not depart from the gist of the present invention.
