Description

  The present invention relates to a massage device that massages limbs such as legs and arms by inflation and contraction of an airbag.

  2. Description of the Related Art Conventionally, there has been known a massage apparatus in which a concave groove portion into which a human leg or arm is inserted is formed, and an air bag that is inflated and contracted by air supply / exhaust is provided on the inner surface of the groove portion (for example, , See Patent Document 1). In the massage device described in Patent Document 1, after the user inserts, for example, a leg into the groove, the two airbags provided on both side surfaces of the groove are inflated and contracted to press the leg from the left and right. Can be obtained.

However, when massaging a leg with a human hand, it is often done so that the outer side or the inner side of the leg is sandwiched from above or below, or it is pushed downward from above. In the conventional massage device that presses in a substantially horizontal direction from both sides, unlike the case where the massage feeling received by the user is a hand, the user may feel uncomfortable.

  This invention is made | formed in view of such a problem, and makes it the subject to provide the massage apparatus which can perform the massage nearer to a hand rub.

In order to solve such a problem, according to the present invention, a concave groove portion that accommodates a limb is formed, and a first airbag that is positioned on an opening side of the groove portion is formed on each of inner surfaces facing each other. When the side and a second air bag located toward the bottom surface from the inner surface provided adjacent side by side in a direction perpendicular to the longitudinal direction of the groove portion, the first airbag and the second airbag, close to each other The first airbag and the second airbag fixed to the inner side surface and provided on the same inner side surface in a pair are inflated substantially simultaneously .

Alternatively, a concave groove portion that accommodates the limb is formed, and on each of the mutually facing inner side surfaces of the groove portion, a first airbag located on the opening side of the groove portion and a second air located from the inner side surface to the bottom surface A bag is provided adjacent to each other in a direction orthogonal to the longitudinal direction of the groove, and the first airbag and the second airbag are respectively fixed to the inner side surface on the side adjacent to each other, The first airbag provided on the side surface and the second airbag provided on the other inner side surface, or the first airbag provided on the other inner side surface and the first airbag provided on the inner side surface A pair of second airbags are inflated substantially simultaneously .

  According to the present invention, since the first airbag and the second airbag are respectively fixed to the inner side surfaces on the side close to each other, the side closer to the side is inflated to perform a massage closer to hand-feeling. It is possible to provide a massage device that can be used.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 shows a massage chair having a leg massage part as a massage device according to the present embodiment. The massage chair 1 includes a base 3, a seat 4 placed on the base 3, armrests 5 and 5 provided on both sides of the seat 4, a seat, A backrest portion 6 is provided at the rear edge of the portion 4 so as to be reclining. The seat part 4 and the backrest part 6 incorporate a treatment element (not shown) such as an airbag for massaging each part of the body of the user (the user) sitting. The massage chair 1 includes, for example, a normal mode and a hand pad mode as massage modes, and a plurality of courses are set for each mode. The user can select a desired mode and course by operating the remote controller 7.

  The leg massage part 2 is provided in front of the base part 3 and can be moved up and down by tilting at an arbitrary angle within a predetermined range with respect to the seat part 4 by a leg massage part electric lifting mechanism (not shown). The outer surface of the leg massage part 2 is covered with a cover (not shown), for example.

  FIG.2 and FIG.3 shows the leg massage part except the cover which covers an outer surface. In the leg massage part 2, the left and right side walls 10 and 10 and the partition wall 12 disposed in the middle of these side walls 10 and 10 are integrally formed, for example, and groove parts 13 and 13 having a U-shaped section (concave shape) are formed. Are formed on the left and right.

These groove parts 13 and 13 are for mounting the legs which are the user's limbs, and airbags 16 which massage the user's legs (lower leg parts) by expansion and contraction on both sides of each groove part 13 (FIG. 4) is built-in. Specifically, an upper airbag 18a as a first airbag and a lower airbag 18b as a second airbag are provided on the inner side surface 17a of each groove 13 on the side wall 10 side, and a partition wall of each groove 13 is also provided. The inner side surface 17b on the 12th side is provided with an upper airbag 18c as a first airbag and a lower airbag 18d as a second airbag. The upper airbag 18a and the lower airbag 18b are juxtaposed in a direction (Y direction, vertical direction in FIG. 2) substantially orthogonal to the longitudinal direction (extending direction, X direction in FIG. 2) of the groove 13 on the inner side surface 17a. The upper airbag 18 a is located on the opening 19 side of the groove 13, and the lower airbag 18 b is located from the inner side surface 17 a to the bottom surface 20 . Similarly, the upper airbag 18c and the lower airbag 18d are juxtaposed in a direction substantially orthogonal to the longitudinal direction of the groove 13 on the inner side surface 17b. The airbag 18d is located.

  Further, the upper airbags 18a, 18c and the lower airbags 18b, 18d are end portions on the sides close to each other, that is, end portions 26, 26 located near the center in the vertical direction (Y direction) of the inner side surfaces 17a, 17b, respectively. 26 and 26 are fixed by screws 28 or the like and attached to the inner side surfaces 17a and 17b. Further, the upper airbags 18a and 18c and the lower airbags 18b and 18d are all substantially the same size.

  The airbag 16 (upper airbags 18a, 18a, 18c, 18c, lower airbags 18b, 18b, 18d, 18d) is inflated and contracted by an air supply / exhaust device 24 shown in FIG. The air supply / exhaust device 24 includes an air pump 21, and upper airbags 18 a, 18 a, 18 c, 18 c and lower airbags 18 b, 18 b, 18 d, 18 d are connected to the air pump 21 by branched supply / exhaust pipes 22. . Each branch line of the air supply / exhaust pipe 22 is provided with an electromagnetic valve 23 constituted by a three-way valve. Each electromagnetic valve 23 selects communication / blocking of the air pump 21 and the airbag 16 and opening of the air supply / exhaust pipe 22. To do it. That is, when the air pump 21 and the airbag 16 are communicated with each other by the electromagnetic valve 23, the compressed air from the air pump 21 flows into the airbag 16 and is supplied to the airbag 16, and the internal pressure changes to expand. Next, when the air pump 21 and the airbag 16 are shut off, the inflated state of the airbag 16 is maintained. Further, when the air supply / exhaust pipe 22 is opened, the airbag 16 communicates with the atmosphere via the air supply / exhaust pipe 22, and the air in the airbag 16 is discharged to the atmosphere and exhausted, so that the airbag 16 contracts.

  The operation of the air pump 21 and the electromagnetic valve 23 is controlled by the control unit 25 in accordance with a control signal from the remote controller 7. The remote controller 7 outputs a signal corresponding to the user operation to the control unit 25.

  When the user of the massage chair 1 selects a predetermined course in the hand massage mode by the remote controller 7, for example, the upper air on the inner side surfaces 17a and 17a of the leg massage unit 2 is controlled by the control unit 25 as shown in FIG. The bags 18a and 18a and the lower airbags 18b and 18b (that is, airbags positioned on the same side surface in the groove portions 13 and 13) are inflated in a pair substantially at the same time. After that, the upper airbags 18a and 18a and the lower airbags 18b and 18b repeat contraction and expansion almost simultaneously at the same timing.

  Here, the upper airbags 18a, 18a and the lower airbags 18b, 18b are one end of the inner side surfaces 17a, 17a near the center in the vertical direction (Y direction), that is, end portions 26, 26, 26, 26 on the sides close to each other. Therefore, when the upper airbags 18a and 18a and the lower airbags 18b and 18b are inflated, the end portion 27 side facing the end portions 26, 26, 26, and 26 is expanded more than the end portion 26 side. be able to. That is, when the upper airbags 18a, 18a and the lower airbags 18b, 18b are supplied with air by the air supply / exhaust device 24, the openings 19 of the grooves 13, 13 are set with the end portions 26, 26, 26, 26 as fixed positions. The side or bottom 20 side expands greatly.

  As a result, a hand massage massage that the outer side of the center of the user's leg L accommodated in the grooves 13 and 13 is simultaneously pressed from the diagonally upward direction and the diagonally downward direction, and the user is sandwiched from above and below. A close sense can be obtained. Further, since the upper airbags 18a, 18a and the lower airbags 18b, 18b are substantially the same size, the user's leg L is pressed with substantially the same force from the obliquely upward direction and from the obliquely downward direction. Can achieve a uniform massage on the top and bottom.

  On the other hand, a pair of upper airbags 18c, 18c and lower airbags 18d, 18d on the inner side surfaces 17b, 17b of the leg massager 2 are inflated almost simultaneously in order to massage the inside of the leg L from the center. It may be. As a result, the same effect as the case of the outer side of the user's leg L can be obtained.

  Furthermore, simultaneous expansion of a pair of airbags (upper airbags 18a, 18a and lower airbags 18b, 18b) on the inner side surfaces 17a, 17a and a pair of airbags (upper airbags 18c, 18c and 18b on the inner side surfaces 17b, 17b) The simultaneous inflation of the lower airbags 18d, 18d) may be performed alternately. Thereby, it becomes possible to massage the outer side and the inner side of the user's leg L evenly and evenly.

  Next, when the user selects another predetermined course in the hand pad mode with the remote controller 7, the control unit 25 controls the upper air on the inner side surfaces 17a and 17a of the leg massage unit 2 as shown in FIG. Bag 18a, 18a and lower airbag 18d, 18d of inner side surface 17b, 17b (that is, air which is located on one line D1 (the line connecting the outer side of the leg and the lower side of the inner side) in the grooves 13, 13) The bags are inflated at the same time in pairs. After that, the upper airbags 18a and 18a and the lower airbags 18d and 18d repeat contraction and expansion almost simultaneously at the same timing.

  As a result, the user's leg L is simultaneously pressed from above and below in the direction along the line D1, and the user has a feeling close to that of a hand massage that is pressed from above to below and from below to above. Can be done. In addition, by pressing in this way, the acupuncture point of the calf part is more accurately stimulated, and a massage can be received in a state where the leg is firmly fixed without being displaced by the pressing force. Furthermore, since the upper airbags 18a and 18a and the lower airbags 18d and 18d have substantially the same size, uniform massage can be realized.

  On the other hand, in order to press the user's leg L in the direction along the other line D2 (a line connecting the upper side closer to the inner side and the lower side closer to the outer side), as shown in FIG. , 17b and a pair of lower airbags 18b, 18b on the inner side surfaces 17a, 17a may be inflated substantially simultaneously. Accordingly, the same effect can be obtained in the direction along the other line D2.

  Furthermore, simultaneous expansion of a pair of airbags (upper airbags 18a, 18a provided on the inner side surface 17a and lower airbags 18d, 18d provided on the inner side surface 17b) on one line D1, and the other line D2 The pair of upper airbags (the upper airbags 18c and 18c provided on the inner side surface 17b and the lower airbags 18b and 18b provided on the inner side surface 17a) may be alternately inflated simultaneously. This makes it possible to massage the direction along one line D1 of the user's leg L and the direction along the other line D2 evenly and evenly.

  The present invention is not limited to the above-described embodiment. For example, in the present embodiment, the leg massage unit that massages the leg has been described. However, for example, the limb that receives the massage may be a body part such as an arm. Not often limited to legs. Moreover, it is not limited to what is provided in a massage chair, It may be provided in another massage machine, and a single body may be sufficient.

  Moreover, in the leg massage part which concerns on this Embodiment, according to the selected course, a pair of airbags located on the same side surface are inflated at the same time, or an opening side located on one inner side surface The pair of airbags and the bottom-side airbag located on the other inner surface are inflated at the same time, or the pair to be inflated with these pairs and the other pair is alternately changed. However, it is not necessary to have all these functions, and any function is sufficient.

  Furthermore, even if the four airbags are not provided on both sides of the groove portion, it is sufficient that the necessary airbags are provided according to at least the functions of the airbags. Further, each airbag may not be a separate body depending on the function of the airbag. For example, by providing one airbag formed with two air chambers communicating with each other on the inner surface of the groove, the upper airbag And the lower airbag can be integrated.
