TECHNICAL FIELD OF THE INVENTION
The present invention attaches a pair of rubbing rollers to a drive shaft rotated by a motor, and a rotating roller having a large number of stimulating projections located on both outer sides of the rubbing roller, and covers the rubbing roller and the rotating roller. The present invention relates to a massager covered with a sheet, and particularly to a cover sheet configuration.
[0002]
[Prior art]
As a massager having a simple configuration mainly used in the 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 rotating rollers having a large number of stimulating projections are attached to both outer sides of the rubbing rollers, respectively, and these rubbing rollers and the rotating rollers 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 rectangular cloth cover.
[0004]
In the case of such a single rectangular cloth cover sheet, the movements of the rubbing roller and the rotating roller are different, such as the rubbing roller moving toward and away from the left and right, and the rotating roller rotating. Since the cover sheet needs play in order to put a body to be massaged, the cover sheet enclosing both rollers has to be large.
[0005]
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 makes it possible to eliminate the looseness of the cover sheet by improving the shape of the cover sheet, improve the fit, and visually clarify that the cover sheet has a different massage function. It is an object to provide a massage machine.
[0007]
[Means for Solving the Problems]
The present invention attaches a pair of rubbing rollers to a drive shaft rotated by a motor, and a rotating roller having a large number of stimulating protrusions located outside the rubbing roller, and covers the rubbing roller and the rotating roller with a cover sheet. In the cover sheet, the expanded shape of the cover sheet is a square shape, and the width in the drive axis direction is a barrel shape such that a central portion is expanded, and the cover sheet has both ends in the drive axis direction. The roller is covered with the roller in a state where the roller is constrained to be orthogonal to the drive shaft, and the color of the roller that covers the roller and the roller that covers the roller is different .
[0008]
With this configuration, since the cover sheet is mounted in a barrel shape with both ends in the drive shaft direction constrained to be orthogonal to the drive shaft, play occurs in the cover sheet covering the kneading roller. Since this play has a barrel shape in which the center part is bulged and both ends are narrowed, it is the minimum play required to put a massaged body such as a foot between massage rollers and perform massage. This makes it possible to eliminate looseness in a portion of the cover sheet particularly covering the rotating roller, thereby improving the fit. Furthermore, since the color of the rubbing roller portion covering the rubbing roller and the rotating roller portion covering the rotating roller of the cover sheet are made 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.
[0011]
Note that the cover sheet may be configured by separately preparing and integrating the kneading roller unit and the rotating roller unit. In this case, the kneading roller portion has a barrel shape in which the width in the direction of the drive shaft is expanded at the center, and the width of the rotating roller portion in the direction of the drive shaft is made uniform.
[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
[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
The massage machine of the present invention will be described with reference to FIGS. 1 to 5 showing one embodiment. Reference numeral 1 denotes a synthetic resin body case having a U-shape in plan view, which is configured to be vertically splittable into two parts. A kneading roller and a rotating roller, which will be described later, are provided between the opposed mounting bases 2 and 3 of the main body case 1. A portion connecting the mounting bases 2 and 3 of the main body case 1 becomes a handle 4. Reference numerals 5 denote legs for installing the main body case on the floor F, which are located at the four lower corners of the main body case 1.
[0014]
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 attached to both outer sides of 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 ten roller shafts 29, for example, and rollers 30 and 31 are alternately mounted on the shaft 29 .
[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 the developed rear view of FIG. 5, the cover sheet 35 includes a rubbing roller portion 51 that covers the rubbing roller 16 and rotating roller portions 52 and 52 that cover the rotating rollers 25 on both outer sides thereof. The three sheets 51, 52, 52 are integrally formed by suturing 54. More specifically, the width of the kneading roller portion 51 in the direction of the drive shaft 9 (in the left-right direction in FIG. 5) is a barrel shape in which the central portion is expanded, and the width of the rotary roller portion 52 on both sides in the drive shaft direction is uniform. The three sheets are stitched 54 on the back side (the side in contact with the rubbing roller 16 and the rotating roller 25) to form a barrel-like shape with a central basic part bulging in a square basic form as a whole. I have.
[0024]
The rubbing roller section 51 and the rotating roller section 52 are made of nylon fabrics of different colors.
[0025]
At both ends of the cover sheet 35 in the direction of the drive shaft 9 (ends of the rotating roller portion 52 and the sewn portion 54 with the rubbing roller portion 51), a passage 56 for passing a string 55 is formed. Is passed through the cord 55. Also, at both ends of the cover sheet 35 in a direction orthogonal to the drive shaft, three pairs of magic 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. Thus, both ends of the cover sheet 35 in the direction of the drive shaft 9 are restrained in a direction orthogonal to the drive shaft 9. 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. 3 and 4 show the state at this time.
[0028]
Here, the length of the rotating roller portion 52 is set to a length that covers the outer periphery of the rotating roller 25 with little play (a vertical dimension in FIG. 5). Further, the kneading roller portion 51 has a barrel shape with its central portion bulging, and the both ends of the cover sheet 35 are constrained in a direction orthogonal to the drive shaft. The length dimension (the dimension in the vertical direction in FIG. 5) is set so as to cover with a play. Since this play has a barrel shape in which the center part is bulged and both ends are narrowed, it is the minimum play required to put a massaged body such as a foot between massage rollers and perform massage. be able to.
[0029]
Accordingly, since the cover sheet 35 attached in this manner covers the kneading roller 16 and the rotating roller 25 with the kneading roller unit 51 and the rotating roller unit 52 that are respectively suitable, there is no looseness particularly in the rotating roller unit. A fitted feel is obtained, and the rubbing roller portion 51 is covered with play between the rubbing roller 16 so that there is no problem in inserting the legs between the rubbing rollers 16 and massaging. it can.
[0030]
Further, since the rubbing roller portion 51 and the rotating roller portion 52 are made of fabrics of different colors, it clearly indicates that the massage device having the different functions of the rubbing roller 16 and the rotating roller 25 is built in the cover sheet 35. And the visual appeal effect can be improved.
[0031]
In the above embodiment, the cover sheet 35 is formed by sewing the independent sheets of the rubbing roller unit 51 and the rotating roller unit 52, but may be formed of one barrel-shaped sheet from the beginning. Also in this case, if the color of the portion corresponding to the rubbing roller portion covering the rubbing roller and the portion of the portion corresponding to the rotating roller portion covering the rotating roller are different, it is possible to clearly indicate that a different massage device is provided inside, and it is visually appealing. The effect can be improved.
[0032]
As in the embodiment, the durability of the cover sheet 35 can be improved by forming the cover sheet 35 by independent sheets of the rubbing roller unit 51 and the rotating roller unit 52. That is, in the case of a single cover sheet, the movements of both rollers are different such that the rubbing roller 16 moves toward and away from the left and right, and the rotating roller 25 rotates. Thus, the cover sheet is easily damaged by a twisting force, but the twisting force does not work by covering each of the rollers 16 and 25 with an independent sheet, the kneading roller portion 51 and the rotating roller portion 52, so that the durability is reduced. Can be improved.
[0033]
Further, by using a material having a higher elasticity than the rotating roller portion 52 as the rubbing roller portion 51 of the cover sheet 35, the massage between the rubbing rollers 16 can be performed even if the play of the rubbing roller portion 51 is small. It does not hinder the insertion and massage of the body.
[0034]
【The invention's effect】
According to the present invention, the cover sheet has a basic shape of a developed square shape and a barrel shape in which the width in the drive axis direction is expanded at the center, and the cover sheet has both ends in the drive axis direction. Is covered with the rubbing roller and the rotating roller while being constrained to be orthogonal to the drive shaft. In this case, the minimum play required for the rotation can be obtained, while the portion of the cover sheet which covers the rotating roller in particular can eliminate the looseness and improve the fit.
[0035]
In addition, by differentiating the colors of the rubbing roller portion that covers the rubbing roller and the rotating roller portion that covers the rotating roller of the cover sheet, it is possible to clearly show that the inside has different massage functions of the rubbing roller and the rotating roller, and The appeal effect can be improved.
