Description

  The present invention relates to a chair type massage machine having a footrest.

  Conventionally, a footrest described in JP-A-8-89540 is known as a footrest that can be used in a chair-type massage machine. This footrest has a body portion in the shape of two U-shaped recesses for leg insertion arranged side by side on the left and right sides. Air bags are provided at three locations on the inner bottom surface.

  In these air bags, air is alternately supplied and exhausted by an air supply / exhaust device installed at a different location and repeatedly inflates and squeezes, thereby massaging the legs and the like.

  The footrest is used to be swingably connected to the front portion of the seat surface portion of the chair type massage machine. Therefore, the main body of this footrest is provided with a connecting shaft for pivoting at the end near the seat surface of the chair type massage machine, and the swing angle can be adjusted around this connecting shaft. In addition, it is necessary to provide a ratchet mechanism for stopping and holding at an appropriate angle.

  Also, depending on the case, depending on the reclining operation on the chair type massage machine side, it may be structured to interlock the swing of the footrest, in this case, various gear structures and link structures for interlocking Alternatively, a motor drive unit or the like needs to be provided around the connecting shaft. However, in the above-described footrest, each recess for inserting a leg is provided so as to penetrate the main body portion in the front-rear direction at the same depth. Therefore, in order to prevent positional interference of the connecting shaft and various mechanisms and devices provided around the connecting shaft with respect to the concave shape, it has been necessary to enlarge the bulge downward as the main body.

  Needless to say, an air pipe is required for each air bag provided on the footrest, but the air hose, hose joint, or control valve used for this pipe causes positional interference with the concave shape around the connecting shaft. In some cases, the main body has to be increased in size and bulk. The present invention has been made in view of the above circumstances, and is capable of accommodating various structures and devices in a compact manner, including a mounting structure for a seat surface portion of a chair-type massage machine, so that the overall size and bulkiness are increased. An object of the present invention is to provide a chair-type massage machine that can prevent the aging.

  In the present invention, in order to achieve the above object, the following technical means are taken. That is, the chair-type massage machine according to the present invention includes a footrest that can be raised and lowered at the front portion of the seating surface portion, and the footrest can be massaged on the main body portion having a leg rest portion and the main body portion. And a provided massage driving unit.

  The massage drive unit is not limited to those that directly or indirectly apply finger pressure, fir, or strike with an air cell or air bag having a bellows structure. In addition, it shall include those that vibrate the diaphragm with electromagnetic equipment. Now, it is assumed that the main body portion is flipped up forward with respect to the seat surface portion of the chair type massage machine and is made substantially horizontal. In this state, the inner bottom surface of the leg rest portion is an inclined surface that inclines forward and downward from the seat surface portion.

  Since it is such a structure, the cavity which becomes so wide as it approaches the side edge part of a seat surface part in the lower part of a leg mounting part in a main-body part can be ensured. Therefore, a connecting shaft for connecting the seat surface portion of the chair type massage machine and the footrest can be provided in the hollow portion, and an angle setting mechanism, a swing interlocking mechanism, or the like can be provided as necessary. Moreover, the inside of this cavity part can also be used as a machine accommodating part for accommodating the piping apparatus and wiring apparatus of a massage drive part.

  In the case where the massage driving unit is provided with an air cell having a bellows structure that performs an expansion and contraction operation by air supply / exhaust control, the following operation can be performed. In other words, air cells are provided on the front end sides of the left and right side walls and on the seat surface side of the inner bottom surface of the leg rest, and among these air cells, acupressure is applied to the upper part of the air cell provided on the inner bottom surface of the leg rest. A piece may be provided.

  In the chair type massage machine according to the present invention, the leg rest provided on the main body of the footrest has an inner bottom surface that is inclined to the front and lower side. A cavity that becomes wider as it approaches the end on the seating surface side can be secured. Therefore, a structure portion for connecting the seat surface portion and the footrest can be provided in the hollow portion, and an angle setting mechanism, a swing interlocking mechanism, or the like can be provided as necessary. Moreover, the inside of this cavity part can also be used as a machine storage part for storing the piping apparatus, wiring apparatus, etc. of a massage drive part.

  From such a thing, the enlargement and bulkiness as a main-body part can be prevented. The massage drive unit is an air cell having a bellows structure, and the air cell is provided on the front end side of the left and right side walls and the seat surface side of the inner bottom surface of the leg rest portion, and the upper portion of the air cell provided on the inner bottom surface of the leg rest portion If the acupressure piece is provided, the main body structure can be used effectively.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 5, the chair type massage machine 2 according to the present invention includes a footrest 1 at the front portion of the seat surface portion 3. In this chair type massage machine 2, the backrest portion 4 can swing automatically or manually with respect to the seat surface portion 3 for reclining, and the footrest 1 also swings the backrest portion 4. The seating surface portion 3 can be swung automatically or manually by interlocking or by an independent operation.

  When the backrest 4 and the footrest 1 are interlocked, when the backrest 4 is tilted backward, the footrest 1 is jumped to the upper position, and on the contrary, the backrest 4 is raised to its original state. The footrest 1 is made to hang down to the lower position. In addition, the chair type massage machine 2 is provided with an appropriate massage driving unit 5 inside the backrest part 4 and the seat surface part 3, for example. The massage driving unit 5 in the figure has an operating element 6 using a roller or the like that is rotatable around a horizontal axis. The operating element 6 includes a driving source (such as an air actuator, an electric motor, or an electromagnetic vibration tool). It is configured to perform a massaging operation constituted by a single or an appropriate combination of moving out / withdrawing / left / right movement / vibration by a movement mechanism 7 such as a screw feed mechanism.

  1 and 2, the footrest 1 of the first embodiment is provided with a leg resting portion 12 that allows a leg 11 to be put in and out with respect to a main body portion 10 having a square disk shape. In addition, the main body 10 is provided with a massage driving unit 13 that can perform a massage operation on the legs 11 supported by the leg rests 12. The shape of the leg rest part 12 will be described in more detail, assuming that the end part (front end part) 12a closer to the tip of the leg 11 to be supported is in a state of jumping up to the front of the seat part 3 (the highest position where it can be raised). To do.

  That is, the leg rest 12 has an inner bottom surface 15 and opposite inner side surfaces 16 on both the left and right sides, and the two directions of the upper side and the toe side (front side) are open. Therefore, in order to place the leg on the leg placing portion 12, it is possible to put in and out (lateral take in and out) by moving the leg in the direction perpendicular to the longitudinal direction (up and down in the illustrated state). Yes.

  The inner bottom surface 15 of the leg rest portion 12 is formed as an inclined surface that gradually becomes deeper (lowers) from the end portion 12b on the seat surface portion 3 side toward the end portion 12a closer to the foot. In addition, a separation hill 17 is provided in a bulging shape at the center in the width direction at the end 12 a near the foot of the leg rest 12, and the left and right legs 11 can be distributed and held on both sides of the separation hill 17. It is like that.

  On the other hand, in the main body portion 10, left and right side wall portions 20 are formed so as to be back-to-back with each inner side surface 16 of the leg rest portion 12. And these both side wall parts 20 enlarge the amount of protrusions upward, so that the end part 12a near the toe | tip is approached with the shape mentioned above of the leg mounting part 12, and the edge part 12b by the side of the seat surface part 3 conversely It is formed in a shape in which the amount of protrusion downward from the inner bottom surface 15 is increased as it approaches.

  For this reason, a hollow portion that becomes higher (wider) closer to the end portion 12 b on the seating surface portion 3 side of the leg rest portion 12 can be formed inside the main body portion 10. Therefore, the inside of this hollow portion can be used as a space for providing a connecting shaft 24 between the footrest 1 and the seating surface portion 3 and, if necessary, an angle setting mechanism and a swing interlocking mechanism.

  In this embodiment, the massage driving unit 13 provided on the footrest 1 includes a first acupressure part 26 for acupressure around the ankle from both the left and right sides, and a second acupressure part 27 for acupressure around the calf from the left and right sides. It is as. As shown in FIG. 3, the first acupressure part 26 has a pair of air cells 29 provided to face one inner side face 16 and the side face of the separation hill 17 in the leg rest part 12.

  The air cells 29 are formed of vinyl acetate or the like into a cylindrical shape whose outer peripheral surface has a bellows structure, and perform an expansion and contraction operation in the axial direction by supplying and discharging air to the inside. Therefore, the air cells 29 are extended in a synchronized manner in the left-right direction, so that both side surfaces of the legs 11 supported by the leg rests 12 are finger pressed in a sandwiched manner.

  Each of the air cells 29 has a larger number of bellows formed in an approximately half-circumferential region facing upward than the number of bellows formed in an approximately half-circumferential region facing downward, around its outer periphery, It is not rotationally symmetric around the axis. In other words, the upwardly arranged bellows include those that do not make one round of the cell outer periphery at the concave and convex circumferential ridge lines.

  Accordingly, when air is supplied to each air cell 29 and extended as described above, the air cell 29 gradually expands toward the concave inner bottom surface 15 as the degree of extension proceeds. Therefore, the leg 11 is subjected to the action of being pressed to the concave bottom surface 15 side simultaneously with the finger pressure. Therefore, the leg 11 is in a stable state during the acupressure, and the leg 11 is naturally not ejected from the leg rest 12.

  Each air cell 29 has a skin material 30 made of cloth or synthetic leather sewn with a bending allowance corresponding to the amount of extension, or a stretchable cloth or rubber sheet (see FIGS. 1 and 2). (Not shown in FIG. 3) so that it does not directly touch the leg 11 or the like. As shown in FIG. 4, the second acupressure part 27 has an opening / closing operation body 34 having a fixing part 32 at the center in the width direction and projecting swing pieces 33 on both sides thereof. It has left and right air cells 35 provided at the lower part of both swinging pieces 33 and an acupressure piece 36 provided at the upper end of the projecting end of both swinging pieces 33 in the opening / closing operation body 34.

  These air cells 35 are also formed of vinyl acetate or the like into a cylindrical shape with an outer peripheral surface having an accordion structure, and perform an expansion and contraction operation in the axial direction by supplying and discharging air to the inside. However, the opening / closing operation body 34 and the acupressure piece 36 correspond to having a predetermined length along the calf of the leg 11, and the left and right air cells 35 shown in the drawing are two in front and rear (see FIG. 1 and FIG. 2), but it may be one by one.

  The opening / closing operation body 34 is formed of a material having flexibility and elasticity, such as a spring plate, a resin plate, or a rubber plate, and causes upward warping and deformation when the air cell 35 is extended, but the air cell 35 Is discharged, it returns to its original shape by the elastic restoring force of the opening / closing operation body 34 itself. The material for the opening / closing operation body 34 is not limited as long as the fixed portion 32 and the swing piece 33 are connected by a hinge structure, but in this case, the swing piece 34 is biased to an open state. Return mechanism is required.

  The second acupressure part 27 has a structure in which the both side surfaces of the legs 11 supported by the leg rest part 12 are pinched in a sandwiched manner by extending all the left and right air cells 35 simultaneously. As each air cell 35 of the second acupressure part 27, the one in which the number of bellows formed around the outer periphery thereof is asymmetrical is used. And it is attached so that the number of bellows formation in the approximately half-circumferential region that faces outward in each arrangement is larger than the number of bellows formation in the inward approximately half-circumferential region.

  That is, the outwardly arranged bellows includes those that do not make one round of the cell outer periphery at the concave and convex circumferential ridge lines. Because of this structure, when air is supplied to each air cell 35 and extended, the acupressure piece 36 gradually extends in the direction in which the left and right ones are directed closer to each other as the degree of extension proceeds. Will do. Therefore, the finger pressure of the leg 11 by the finger pressure piece 36 is smoothly performed, and sufficient finger pressure can be expressed.

  Therefore, the leg 11 is in a stable state during the acupressure, and the leg 11 is naturally not ejected from the leg rest 12. The opening / closing operation body 34 and the acupressure piece 36 are covered with the skin material 30 (see FIGS. 1 and 2, omitted in FIG. 4) formed so as to have a bending allowance corresponding to the swing amount. It is designed not to touch the leg 11 directly.

  In addition, although illustration is abbreviate | omitted, as the massage drive part 13, it is also possible to provide the 3rd acupressure part which made the ankle and the calf acupressure from the back side to the inner bottom face 15 of the leg mounting part 12. FIG. In such a case, each of the first acupressure part 26, the second acupressure part 27, and the third acupressure part may be independently operated, or may be operated with a predetermined interlocking relationship. Good. In the case of interlocking, as described above, the first acupressure part 26 and the second acupressure part 27 both have an action of preventing the leg 11 from being expelled from the leg rest part 12, so that these first, The second acupressure parts 26 and 27 and the third acupressure part can be controlled to supply air at the same time.

  Of course, the first and second acupressure parts 26 and 27 and the third acupressure part are operated individually, and even if they happen to overlap with each other, the air supply / discharge timing is always different. There is no need to perform complicated control to maintain the predetermined relationship. Advantages common to the first acupressure part 26 and the second acupressure part 27 are, in particular, the acupressure using air pressure, so that the acupressure does not exceed a predetermined pressure and the air cells 29 and 35 Since it is cylindrical, it can be mentioned that the expansion and contraction can be performed smoothly and efficiently.

  In the first acupressure part 26 and the second acupressure part 27 (that is, the massage driving part 13), an air hose, a hose joint, a control valve, and the like necessary for the air piping are hollow parts secured in the main body part 10 shown in FIG. Can be provided inside this as the machine storage portion 25. In addition, as shown in FIG. 6, the usage which inserts a foot | leg part with respect to the 1st acupressure part 26 or the 2nd acupressure part 27 can also be performed.

  Further, as shown in FIG. 7, in the first acupressure part 26, for example, a hemispherical acupressure piece 40 is provided on the projecting end face side of each air cell 29 to increase the acupressure and the acupressure effect. It is also possible to do so. 8 and 9 show a second embodiment of the chair type massage machine according to the present invention. The most different point of the second embodiment from the first embodiment is that a step 45 capable of supporting the sole of the leg 11 is provided on the leg resting portion 12. The machine storage portion 25 is formed.

  Accordingly, piping equipment, wiring equipment, and the like (not shown) of the massage driving section 13 can be stored in the machine storage section 25. In addition, as the massage driving unit 13, a fourth acupressure part 46 that performs a massage operation on the sole can be provided in Step 45. FIG. 10 shows a third embodiment of the chair type massage machine according to the present invention. The third embodiment is different from the first embodiment in that the operating body 34 of the second acupressure part 27 is provided so as to protrude rearward from the fixing part 32.

  In this case, when the air cell 35 is extended, the acupressure piece 36 operates as shown in FIG. 10 with the fixed portion 32 as a rotation axis extending in the width direction, and acupressures the leg 11. By the way, the present invention is not limited to the above embodiments. For example, in the massage driving unit 13, a direct acupressure structure using the air cell 29 is used like the first acupressure part 26, or an indirect acupressure structure using the air cell 35 as a driving source like the second acupressure part 27. Besides these, it is also possible to drive these motors. Further, the arrangement and the number of the acupressure operation units 26 and 27 can be changed as appropriate, and the number of air cells 29 and 35 used can be changed as appropriate.

  Thus, the structure, massage operation content, operation principle, etc. of the massage driving unit 13 are not limited at all.
