Description

  The present invention relates to a massage device such as a manual massager using a roller or a massage chair.

  Conventionally, there are many types of manual massagers using rollers that differ in the number and shape of the rollers, the shape of the mounting base of the rollers and the shape of the handle, etc. The entire instrument is reciprocated linearly in the pressed state. Therefore, the magnitude of the massage action by these manual massagers is determined by the pressing force of the roller on the body and the speed of the reciprocating operation.

  On the other hand, there is a massage chair as a typical example of performing automatic massage by mechanical means. Thus, this massage chair basically rolls along both sides of the spine of the sitting user by driving up and down a pair of left and right rollers protruding from the front side of the backrest. A massage action can be obtained by a pair of stimuli, but depending on the model, there is also an apparatus that enhances the massage effect by adding vibration, forward / backward projection amount change, swinging of the head, etc. to the raising / lowering operation of the roller pair.

  With a manual massager using conventional rollers, in order to obtain a large massage action, it is necessary to increase the pressure of the roller on the body or to speed up the reciprocating movement, which requires much labor. On the other hand, there was a problem that it could be tired and it was not easy to use. In addition, in the conventional massage chair, a large massage action cannot be obtained only by raising and lowering the roller pair. To compensate for this, when adding vibration of the roller pair, change in the forward and backward protrusion amount, swinging of the head, etc. Incorporation of an operating mechanism complicates the structure, resulting in high manufacturing costs and failure.

  In view of the above-mentioned situation, the present invention can exert a large massage action with a very simple structure as a massage device using a roller, a strong massage effect can be obtained by lightly operating with a manual type, and even with an automatic type, The object is to provide a product that can provide a strong massage effect only by reciprocating motion and can be manufactured at low cost without requiring any special motion mechanism.

  In order to achieve the above object, a massage tool according to claim 1 of the present invention is provided with reference numerals in the drawings, and the rotational axes P and P of the bases 1 and 10 are formed in a square shape. A configuration in which at least one pair of idler rollers 20, 20A, 20B to be arranged is attached is adopted.

  The invention according to claim 2 is the massage device according to claim 1, in which the rotation axis directions P and P are arranged in a square shape and the rotation axis directions P and P are opposite to each other. It has the structure which has 20 A of idle roller pairs arrange | positioned in a letter shape.

  According to a third aspect of the present invention, in the massage device according to the first or second aspect, the base body 1 forms a grip portion of a manual massager.

  According to a fourth aspect of the present invention, in the massage device of the first or second aspect, the base body 10 is the backrest portion 11 of the massage chair 11, and the idle roller pairs 20 </ b> A and 20 </ b> B are moved up and down on the front side of the backrest portion 11. It is supposed to be attached as possible.

  According to the massage device of the first aspect of the present invention, since the two idler rollers making a pair are arranged with the mutual rotation axis directions being C-shaped, both idler rollers are placed on the user's body. When the massage tool is moved with the lightly pressed against the crossing side in the rotation axis direction of both idle rollers, the rolling with the slip of both idle rollers inclined with respect to the traveling direction, As a result of the body surface part of the contact part being drawn toward the center between the two rolling rollers, the two rolling rollers bite into the body and grip the muscles, and the gripped muscles are between the two rolling rollers. When it is removed, it will return to its original state, and a powerful massage effect will be obtained. Further, excessive friction with respect to the contact portion is prevented by rolling of both idle rollers. On the other hand, the massage device itself is simply provided with a pair of free-rolling rollers on the base body, so that it can be manufactured structurally and inexpensively.

  According to the invention of claim 2, since it has a plurality of pairs of idler rollers that reverse the C-shaped arrangement in the direction of the rotation axis, both in the forward movement and in the backward movement in the reciprocating operation of the massage tool, While one idler roller pair bites the body, the body surface part between both idler rollers is stretched to the left and right by the other idler roller pair immediately before or immediately after that, and a better massage effect is achieved. can get.

  According to the invention of claim 3, particularly as a manual massager, a strong massage effect can be obtained with a light operation, and a user-friendly device can be provided.

  According to the invention of claim 4, particularly as a massage chair, a powerful massage effect can be obtained only by the lifting and lowering operation of the pair of idler rollers, and no other special operation mechanism is required, so that the structure is simple and inexpensive. What you can make is provided.

  Hereinafter, embodiments of a massage device according to the present invention will be specifically described with reference to the drawings. 1 to 4 are manual massagers according to the first embodiment, FIGS. 5A and 5B are principles of massage according to the present invention, FIGS. 6 and 7 are manual massagers according to the second embodiment, and FIG. The manual massage device of 3rd embodiment and FIG. 9 show the massage chair of 4th embodiment, respectively.

  The manual massager according to the first embodiment is arranged such that mutual rotation axis directions P and P are arranged in a square shape on one side of a slightly curved thick plate-like substrate 1 made of wood or a hard synthetic resin molding. An idle roller pair 20 composed of individual idle rollers 2 and 2 is provided.

  Each idler roller 2 is formed by fitting and integrating a rubber ring 2b on the outer periphery of a roller body 2a made of a hard synthetic resin molding (see FIG. 4), and is made of a metal having a U-shape when viewed from the front. The support frame 3 is pivotally supported by a pivot pin 4 horizontally mounted between the tops of both side triangular protrusions 3b, 3b. The substrate portion 3a of the support frame 3 is screwed through a cushion rubber layer 5. By being fixed to the base 1 with 6 and 6, it is attached to the base 1 as a caster form.

  In such a manual massager, the user grasps the base 1 and gently presses the idle rollers 2 and 2 against the body part to be massaged, and the entire idle roller 2 and 2 rotates in this pressed state. A powerful massage effect can be obtained simply by moving along the midline O of both rotation axis directions P and P with the crossing side of the axial directions P and P, that is, the opening side of the C-shaped front.

  The principle of this massage action will be described with reference to FIGS. That is, the crossing of the rotation axis directions P and P of the two rolling rollers 2 and 2 with the rotation rollers 2 and 2 lightly pressed against the body M with the rotation axes P and P arranged in a C shape. When moving along the middle line O of both rotation axis directions P and P with the side facing forward, both free-rolling rollers 2 and 2 try to roll due to contact resistance. As shown in (A), since it is inclined with respect to the traveling direction and away from the center line O, a strong braking action is generated at the contact portion, causing rolling with rotation, that is, rotation delay, and contact resistance. As shown in FIG. 5 (B), the body surface of the body M is drawn toward the center between the two rolling rollers 2 and 2, and the two rolling rollers 2 and 2 bite into the body accordingly. Grab muscles. The gripped muscles are moderately pressed from both sides by the two rolling rollers 2 and 2 and then return to the original state between the two rolling rollers 2 and 2. You will receive a strong massage action. Moreover, since both the rolling rollers 2 and 2 roll without stopping rotation, excessive friction with respect to the contact portion can be avoided, and the feeling of use becomes comfortable.

  In order to obtain such a powerful massage effect, the crossing angle θ (see FIG. 2) in the rotation axis directions P and P of the two rolling rollers 2 and 2 should be set in a range of 60 to 150 degrees. In particular, a range of 70 to 120 degrees is recommended.

  The manual massager of the second embodiment shown in FIGS. 6 and 7 has a pair of left and right chevron bulges 1a, 1a protruding from one side of a thick plate-like substrate 1 made of a hard synthetic resin molding. Each bulging portion 1a has a rectangular pocket portion 1b that opens in a rectangular shape on the top side, and a free-rolling roller 2 protrudes partially from each pocket portion 1b through a pivot pin 4 so as to be rotatable. It is held in. The left and right pocket portions 1b, 1b are oriented so that the rotational axis directions P, P of the idler rollers 2, 2 of the idler roller pair 20 held by each other are in the shape of a square like the first embodiment. Is set.

  In the manual massager of the second embodiment, as in the first embodiment, the idle roller 2 is lightly pressed against the body part to be massaged, and the rotational axis direction P of both idle rollers 2 and 2 A powerful massage effect can be obtained simply by moving along the middle line O with the crossing side of. Thus, in this second embodiment, only a part of each rolling roller 2 protrudes from the base 1, so that the appearance is good and the ridge-shaped bulging portion 1a is made smooth with no corners. Since the contact with the skin can be softened and the metal holding frame as in the first embodiment is unnecessary, there is an advantage that the assembly can be easily manufactured and the cost can be reduced by mass production.

  The manual massager of the third embodiment shown in FIG. 8 has a substantially bowl-shaped thick plate-like substrate 1 made of wood or a hard synthetic resin molded product on one side of the thick plate-like substrate 1, and the rotational axis directions P and P are in a C shape. A pair of idle rollers 20A composed of two idle rollers 2 and 2 and an idle roller composed of two idle rollers 2 and 2 in which the rotation axis directions P and P are arranged in a reverse C shape. The pair 20 </ b> B is provided so as to face the longitudinal direction of the substrate 1. In addition, the base body 1 is provided with recesses 1c and 1c at the center portions on both the left and right sides so as to be easily gripped. Thus, the holding structure of each idler roller 2 and the attachment structure to the base body 1 are the same as those in the first embodiment.

  In the manual massager of this third embodiment, the user holds the base 1 and lightly presses the rolling roller 2 to the body part to be massaged. A powerful massage effect can be obtained simply by reciprocating in the middle line direction O of 8. That is, in both the forward movement and the backward movement in the reciprocating motion, the idle roller pair on the front side in the traveling direction (for example, 20A) bites into the body, and immediately after that, the idle roller pair on the rear side (for example, 20B), the body surface portion between the two rolling rollers is stretched to the left and right outside, and a better massage effect can be obtained by combining both actions.

  The manual massager to which the present invention is applied is not limited to the configurations of the first to third embodiments, and is arranged in a square shape in which the rotation axis directions P and P of the two idle rollers 2 and 2 are in the same direction. A configuration having a plurality of pairs of idler rollers, a configuration in which the rotation axis directions P and P are C-shaped and reverse C-shape, and one of them is two or more pairs, and the rotation axis directions P and P are opposite to the C-shape In contrast to the third embodiment, both of the C-shaped two pairs and the configuration in which the crossing sides of the rotation axis directions P and P face the inside of the base 1 are included. However, in the configuration in which the rotation axis directions P and P have two pairs of idler roller pairs in which the C-shape and the reverse C-shape are formed, the third is more than the crossing side of the rotation axis directions P and P facing the inside of the base body 1. A better massage effect is obtained when facing outward as in the embodiment. Moreover, also about the structure which has several pairs of idle roller pairs, each idle roller 2 is hold | maintained by the pocket part 1b provided in the base | substrate 1 like 2nd embodiment, and only a part of the roller 2 is this base | substrate. It is good also as a form protruded from 1. In addition, in these manual massagers, various design changes can be made in addition to the first to third embodiments, for example, the rolling rollers 2 and 2 are formed into a spherical shape, and a handle and a handle are attached to the base 1. It is.

  The present invention can also be applied to an apparatus that performs automatic massage by mechanical means. For example, in the massage chair 10 of the fourth embodiment shown in FIG. 9, two pairs of upper and lower rotating rollers 20 </ b> A and 20 </ b> B are projected on the front side of the backrest portion 11 via the pivot piece 13. The idle roller pairs 20A and 20B are driven up and down along the vertical guide grooves 12 and 12 by an elevating mechanism (not shown), but the idle rollers 2 and 2 of the upper idle roller pair 20A have rotation axis directions P, While P is arranged in an inverted C shape, the rotation rollers 2 and 2 of the lower idler roller pair 20B are arranged in a C shape in the rotation axis directions P and P.

  Therefore, according to the massage chair 10, the pair of idler rollers 20 </ b> A and 20 </ b> B are moved up and down while the user sitting down leans back against the backrest 11, so that the idler roller pair 20 </ b> A is driven. , 20B rolls while rolling along both sides of the user's spine, but when either ascending or descending, one rotating roller pair bites the body and exerts a powerful massage action In addition, the body surface portion is stretched by the other idler roller pair, and a good massage effect can be obtained. Further, in this massage chair 10, it is only necessary to drive the two pairs of idler rollers 20A and 20B up and down, and a good massage can be performed without using vibration, forward / backward projection amount change, swinging swinging, etc. in combination. As a result, a special operation mechanism is not required, the configuration is simplified, and the manufacturing cost is reduced.

  In such a massage chair, the rotational axis directions P and P are arranged in the shape of a letter C, and there is only one pair of idler rollers 2 consisting of two idler rollers 2 and 2 with the same rotational axis. A configuration having a plurality of idler roller pairs in which the directions P and P are arranged in a C shape with the same direction, a configuration in which the rotation axis directions P and P are a C shape and an inverted C shape, and one of them is two or more pairs The rotation axis directions P and P are two pairs of a C-shape and an inverted C-shape, and conversely to the fourth embodiment, the crossing sides of the rotation axis directions P and P are inside the base body 1, It includes any of a configuration having a normal roller pair whose rotation axis direction is along the left-right direction together with the roller pair.
