  The present invention will be described based on embodiments shown in the accompanying drawings. 1 to 4 show the appearance of an example of a massage machine according to an embodiment of the present invention, and FIGS. 5 to 10 show the frame structure of an example of a massage machine. Hereinafter, 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.

  As shown in FIGS. 1 to 4, an example of the massage machine is of a chair type (sofa type), and has a seat portion 1 on which a user (not shown) is seated, and a posture seated on the seat portion 1. An ottoman 2 that holds the left and right legs of a user, a backrest 3 on which a user in a sitting position leans against his back, and left and right armrests on which a user in a sitting position can place an elbow tip 4 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 notch 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 compared to the partition wall 7 and the outer wall 8 is provided. Is low.

  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.

  FIG. 1A and FIG. 2 show a state where the ottoman 2 is hidden under the seat portion 1 in the stored state, and FIG. 1B and FIG. 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.

  Then, 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 regulates the sliding forward. At the same time, it begins to rotate so as to lift the tip portion upward (see arrow a in FIG. 1C). 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 the toe side is tilted forward (see arrow b in FIG. 1 (c)), the back-to-back posture with the toe holding surface 6 facing backward, 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 rotation position or in the vicinity of the maximum rotation 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 with the toe holding part B as shown in 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 below the seat portion 1, and the state shown in FIG. 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 lower leg holding part A and the toe holding part B, the slide frame 14 that supports the ottoman 2 as a whole is connected to the support leg 12 so as to be slidable back and forth. The crus holding part A and the toe holding part B are connected rotatably 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 slide 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 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 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 closer to the seat portion 1. Therefore, when the foot-holding surface 6 of the foot-holding portion B is pushed in with the sole, the foot-holding portion B rotates so as to tilt the toe side forward, and if the pushing-in of the sole is returned, this is accompanied. 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.

  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 spring-biased 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 37 that connects the lever 36 and the swing arm 35. When the operating portion 38 of the lever 36 is pulled upward, the swing arm 35 swings in a predetermined direction via the wire 37, and the stopper 33 is moved to an upper position where it does not come into contact with the stopper receiver 34.

  The biasing means 32 includes a coil spring 39 interposed between the rail member 15 and the slide frame 14. The coil spring 39 is in a compressed state when the slide frame 14 is in the storage position below the seat 1 and applies a forward biasing force to the slide frame 14. When the slide frame 14 moves forward by the predetermined distance d, the urging force applied by the coil spring 39 does not have a great influence on the advance of the slide frame 14.

  When the ottoman 2 is in the storage position, the movement of the slide frame 14 is prohibited by engaging the stopper 33 with the stopper receiver 34. 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. In conjunction with this release, the entire ottoman 2 can be projected forward by a predetermined distance d by the biasing force of the 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 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 (see arrow b in FIG. 1C) 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 to rotate forward so that the forward movement is restricted by the connecting member 23 from the middle and a rotational driving force is applied and the tip part is lifted upward (see arrow a in the figure). . 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 crus holding portion A and causing discomfort.

  And a user can massage a leg part by appropriate treatment means, such as an airbag arrange | positioned in the lower leg holding | maintenance part A or the foot tip holding | maintenance part B in the state which set the ottoman 2 like FIG. it can. 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 forward as far as possible, and also about the crus holding part A that rotates in conjunction with the pushing of the toe holding part B. 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.

  From here, further, when the foot tip holding part B is pushed backward at the heel portion against the urging force of the coil spring 39, the stopper 33 once rides on the stopper receiver 44 provided on the slide frame 14 side and then the stopper receiver 44 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.

  In the massage machine described above, the slide frame 14 may be slid forward and backward, and the crus holding part A and the toe holding part B may be electrically rotated. Alternatively, the ottoman 2 consisting only of the crus holding part A may be stored below the seat part 1, or the foot part holding part B rotates integrally with the crus holding part A and below the seat part 1. The structure may be stored in the housing. Other configurations can be appropriately changed in design as long as they do not depart from the gist of the present invention.
