TECHNICAL FIELD OF THE INVENTION
The present invention is a massage machine in which a pair of rubbing rollers and a rotating roller having a large number of stimulating projections are respectively attached to a drive shaft rotated by a motor, and the rubbing roller and the rotating roller are covered with a cover sheet, particularly And the configuration of the cover sheet.
[0002]
[Prior art]
As a massager having a simple configuration mainly used at home, for example, as disclosed in Japanese Utility Model Publication No. 7-49943 (A61H15000), the massage machine is driven in a direction opposite to a drive shaft rotated by a motor. 2. Description of the Related Art A massaging machine in which a pair of inclined rubbing rollers and a rotating roller having a large number of stimulating protrusions are respectively attached, and the rubbing roller and the rotating roller are covered with a cover sheet has been widely used.
[0003]
The cover sheet of this type of massage machine has conventionally been constituted by a single cloth cover.
[0004]
In the case of such a single cloth cover sheet, the movements of the rubbing roller and the rotating roller are different, such as the movement of the rubbing roller approaching and separating from the left and right, and the rotation of the rotating roller. On the contrary, there is a problem that a twisting force is applied to the cover sheet and the cover sheet is easily damaged.
[0005]
In addition, since the cover sheet needs to have play to put the body to be massaged such as legs between the rubbing rollers, the cover sheet that wraps both rollers must be large enough to ensure the operation of the rubbing rollers. I had no choice. As a result, the part of the cover sheet that covers the rotating roller, in particular, tends to be wrinkled and wrinkled, has a poor fit, and has a loose appearance even when viewed as a whole. While having a different massage function of a rotating roller, it lacked visual appeal.
[0006]
[Problems to be solved by the invention]
The present invention improves the durability of the cover sheet by covering the kneading roller and the rotating roller with a cover sheet that is adapted to each, thereby eliminating looseness of the cover sheet, improving the fit, and further providing a different massage function. An object of the present invention is to provide a massage machine capable of visually confirming that it is provided.
[0007]
[Means for Solving the Problems]
The present invention provides a massage machine in which a pair of rubbing rollers and a rotating roller having a large number of stimulating projections are attached to a drive shaft rotated by a motor, and the rubbing roller and the rotating roller are covered with a cover sheet. sheet, as well as configured by integrating the rotation roller portion covering the rotating roller and massaging roller portion covering the individually-prepared massaging rollers to respectively fit to the outer periphery of the rubbing roller rotating roller, of the cover sheet The color of the kneading roller and the rotating roller is different .
[0008]
With this configuration, the kneading roller and the rotating roller can be covered with the cover sheets respectively adapted to each other, so that the durability of the cover sheet can be improved, and the cover sheet can be prevented from loosening and the fit can be improved. Further, since the colors of the rubbing roller portion and the rotating roller portion of the cover sheet are different, it is possible to clarify that the inside of the cover sheet has different massage functions of the rubbing roller and the rotating roller.
[0009]
Here, the cover sheet is integrated by sewing the kneading roller portion and the rotating roller portion. With this configuration, the cover sheet can be easily made.
[0011]
In addition, if the rubbing roller portion and the rotating roller portion are integrated so that the rubbing roller portion of the cover sheet can be adapted to the outer periphery of the rubbing roller with more play than the rotating roller portion, the body to be massaged can be placed between the rubbing rollers. It does not hinder insertion and massage.
[0012]
In addition, if the rubbing roller portion of the cover sheet is made of a material that is more elastic than the rotating roller portion, even if the play of the rubbing roller portion is small, the massager can be inserted between the rubbing rollers and massaged. Does not interfere with

A motor 6 is provided in the mounting base 3. The motor 6 is fixed to the mounting base 3 by a mounting bracket 8 via a rubber vibration isolator 7. The driving force of the motor 6 is transmitted to the drive shaft 9 via the reduction gears of the worm 12 and the worm wheel 11. Reference numeral 10 denotes a gear case that houses the reduction gear. The worm wheel 11 is fixed to the drive shaft 9, and the worm 12 is fixed to the shaft of the motor 6. Reference numeral 13 denotes a control unit for controlling the motor 6, and reference numeral 14 denotes a power cord.
[0015]
The drive shaft 9 is rotatably supported by bearings 15, 15 between opposing walls of the mounting bases 2, 3. The bearings 15 are sandwiched between the upper and lower body cases 1.
[0016]
At the center of the drive shaft 9, a pair of rubbing rollers 16, 16 inclined in opposite directions are attached. The rubbing roller 16 is fixed in the rotation direction with respect to the drive shaft 9 and is slidable in the direction of the axis L, and is rotatable via a plurality of steel balls 18 on the outer periphery of the rubbing base 17. It is composed of an idler 19 mounted. The idler portion 19 is composed of a first mounting plate 20 and a second mounting plate 21 each having a sliding surface for the steel ball 18, and an elastic body such as rubber whose lower end is sandwiched between the mounting plates 20 and 21. It is composed of a massaging unit 22. Reference numeral 23 denotes a screw for fixing the mounting plates 20 and 21 via the lower end of the massaging section 22. A plurality (approximately 10) of protruding portions 24 protruding inward are formed in the massaging portion 22.
[0017]
Here, when the drive shaft 9 rotates, the kneading base 17 rotates. However, when the load is applied by inserting the legs between the idler portions 19, 19, the idler portion 19 moves to the rigid ball 18. The non-rotating state is maintained with rolling, and the sliding surface of the steel ball 18 is not parallel to the axis L of the drive shaft 9 but is inclined. Repeat the separating operation. Therefore, it is possible to massage the body to be massaged such as the foot sandwiched between them. At this time, the projection 24 presses the body to be massaged.
[0018]
Rotary rollers 25, 25 are mounted outside the pair of rubbing rollers 16, 16 of the drive shaft 9. The rotary roller 25 is fixed to the drive shaft 9 and has a cylindrical first base 27 having a flange 26 at one end and an open end at the other end, and a disc-shaped first base 27 closing the open end at the other end of the first base 27. , A plurality of roller shafts 29 bridged in parallel with the drive shaft 9 between the flange 26 and the second base 28, and a plurality of roller shafts 29 rotatably mounted on the roller shaft 29. And rollers 30 and 31 of different types. One 30 is formed with two stimulating projections 32 having the same shape, and the other is formed with a large stimulating projection 33 on both sides and a flat stimulating projection 34 therebetween. It is a thing. There are, for example, ten roller shafts 9, and rollers 30 and 31 are alternately mounted on the shaft 9.
[0019]
The rotation roller 25 is rotated by the rotation of the driving shaft 9, and the stimulating projections 32, 33, 34 of the rollers 30, 31 massage (rolling massage) a massaged body such as a foot.
[0020]
Between the pair of rubbing rollers 16 and the rotating roller 25, a coil spring 37 that urges the rubbing rollers 16 in a direction to always approach each other is wound in a compressed state. A spacer 40 is fixed to the drive shaft 9 between the pair of rubbing rollers 16, 16, and regulates the approach amount of the pair of rubbing rollers 16, 16 urged by the coil spring 37.
[0021]
Thereby, when putting the foot between the rubbing rollers 16 and 16 and rubbing, when the load applied to the rubbing roller 16 increases, the protrusion 24 of the rubbing portion 22 is initially compressed, but when the load further increases. The elastic body 37 is compressed to retract the pair of rubbing rollers 16, 16 away from each other, thereby preventing an excessive pressure from being applied to the foot as the massaged object. The spacer 40 is provided with two auxiliary rollers 38 that are rotatable. This is used, for example, when stimulating the sole while rubbing the foot with the rubbing roller 16.
[0022]
The rubbing rollers 16, 16 and the rotating roller 25 are covered with a flexible cover sheet 35 made of, for example, nylon. A large number of ribs 36 are formed on the outer periphery of the first base 27 to prevent the cover sheet 35 from being rolled up during massage.
[0023]
As shown in FIG. 5, the cover sheet 35 is composed of a rubbing roller portion 51 covering the rubbing roller 16 and rotating roller portions 52, 52 covering the rotating rollers 25 on both outer sides thereof. , 52, 52 are integrally formed by suturing 54. More specifically, the joint between the rubbing roller 51 and the rotating roller 52 is stitched with a bulge 53. As shown in FIG. 1, the stitches 54 are provided on the back side of the cover sheet 35, that is, on the side in contact with the rotating roller 25 and the rubbing roller 16. The size of the rotating roller portion 52 is adapted to fit the outer periphery of the rotating roller 25, and the size of the rubbing roller portion 51 is adapted to fit with the outer periphery of the rubbing roller 16 with play. Is set.
[0024]
The rubbing roller section 51 and the rotating roller section 52 are made of nylon fabrics of different colors.
[0025]
At one end portion of the cover sheet 35 (an end portion of the rotating roller portion 52 opposite to the stitching portion 54 with the rubbing roller portion 51), a passage 56 for passing a cord 55 is formed. 55 are passed through. At the other end of the cover sheet 35, three pairs of fasteners 57 and 58 that are connected to each other are mounted.
[0026]
In order to attach the cover sheet 35, flanges 59, 59 are formed on opposing walls of the attachment bases 2, 3. More specifically, it is provided around the distal end of a short cylindrical body protruding from the opposing walls of the mounting bases 2 and 3. A fitting groove 60 having a short cylindrical body as a bottom is formed between the flange 59 and the facing wall. On the back side (lower side) between the mounting bases 2 and 3, a support stay 61 is provided integrally with the flanges 59 and 59 as shown in FIG.
[0027]
To attach the cover sheet 35, the cover sheet 35 is put on both rollers 16, 25, 25, and the strings 55 at both ends are inserted into the fitting grooves 60, and both ends 62 of the strings 55 are placed behind the fitting grooves 60. Come over. Further, the other end portions of the cover sheet are led out onto the support stay 61, and the three sets of magic fasteners 57 and 58 are attached to each other by being joined together. That is, the cover sheet 35 is detachably attached so as to surround the rollers 16, 25, 25. 3 and 4 show the state at this time.
[0028]
Since the cover sheet 35 attached in this manner covers the kneading roller 16 and the rotating roller 25 with the kneading roller portion 51 and the rotating roller portion 52 which are adapted to each other, the touch that fits without any looseness especially in the rotating roller portion is provided. Is obtained.
[0029]
Further, even if the rollers 16 and 25 make different movements and apply forces in different directions to the cover sheet, since they are covered with separate members 51 and 52, respectively, the twisting force does not work, and it is hard to be damaged and durable. Performance can be improved.
[0030]
In addition, since the rubbing roller portion 51 is covered with a play between the rubbing roller 16 and the rubbing roller portion 51, there is no problem in inserting the legs between the rubbing roller 16 and performing the massage.
