However, conventional soles are solely independent products, and are usually purchased personally by users and used at workplaces, and therefore cannot be said to be continuously available. However, after all, there is a problem that it can only be used as a temporary hobby. Also, the use of personal footwear, which is personal in places such as the workplace, is not always welcomed in terms of the work environment, and it is difficult to continue using it in this regard.

Disclosure of the invention

SUMMARY OF THE INVENTION An object of the present invention is to provide a chair and a sole acupressure device having a structure for acupressure on the sole that can be easily used whenever necessary without impairing the work environment. To achieve this object, the present invention is configured as follows.

The chair according to the present invention is characterized in that a sole acupressure device is attached to the upper end of the arm end of a leg with a casserole in which a plurality of arms are radially arranged. For this reason, even if you feel stiff shoulders or swelling of your feet while working, you can wear them on the legs of your sitting chair. You can easily acupressure the sole of the foot just by putting the sole on the sole of the foot. At this time, the soles of the chairs are covered with acupressure pads on the upper part of the chair, so if you put your feet here, the part that hit the seat of the thighs will rise, and the weight of the feet will be reduced. Naturally applied as a pressing force against the sole Shiatsu, there is no need to consciously press the sole against the sole Shiatsu, and an ideal shiatsu state can be obtained. For this reason, if the user has a simple knowledge of the so-called sole of the sole, a sufficient acupressure effect can be expected by placing an appropriate sole position on the sole acupressure device. The sole acupressure device is a hemisphere approximately the size of a golf ball or ping-pong ball, for example, and does not impair the design or function of the chair even if it is worn on the leg of the chair. Since there is no image of back shiatsu, it can be said that it does not impair the work environment. In the chair of the present invention, at least one of the plurality of arms of the leg with a casserole is fitted with a sole acupressure device. In general, four or five radial arms are used for chairs with cascading legs in office chairs, and in the present invention, at least one of them is acupressure on the sole. You just need to put on the tool. In addition, since it is most common to apply acupressure on both feet at the same time, the most desirable mode is to wear a total of two sole acupressure devices, one on each adjacent leg arm. Of course, if you want to apply shiatsu regardless of the position of the leg arm rotation, you may attach a sole acupressure device to all leg arms. In the chair according to the present invention, at least two of the plurality of arms of the leg with the casserole are fitted with the same-shaped sole acupressure device. This is the most common usage. On the other hand, according to the present invention, at least two of the plurality of arms of the leg with a casserole may be equipped with soles of different shapes. Here, different shapes of sole acupressure tools have different curvatures at the tip sphere pressing the sole. That is, the sole acupressure device to be mounted on the chair of the present invention includes a so-called soft type in which the curvature of the tip sphere is increased to form a gentle curved surface, thereby reducing finger pressure when the foot is put on the foot. A so-called hand-type, which increases the finger pressure when the foot is put on by preparing a curved surface with a small curvature of the ball, is prepared. By doing so, you can use soft or hard type soles depending on the situation at the time. Further, as the sole acupressure device having a different shape, the height of the tip ball portion for pressing the sole may be different. For example, a soft evening with a large curvature at the tip sphere Even if the sole of the shoe has a fingertip, the higher the height of the fingertip, the less the finger pressure is. This makes it possible to use different types of acupressure, soft or hard, depending on the situation at that time. In the chair according to the present invention, the sole of the foot is screwed into the upper end of the arm of the leg with the casserole, and is fixed with a nut, riveting or welding. The simplest method of fixing is to drill a hole in the leg arm and cut the screw with a tap, and then screw the bolt formed integrally with the sole fingertip into this screw hole and fix it. As a result, even if the chair is already being used in the workplace, the chair of the present invention can be implemented by attaching the sole acupressure device by simple work at the site. In the chair according to the present invention, a sole acupressure device may be fixed to the upper end of the arm of the leg with the cauldron with a band. This fixed band type is easy to install and can be used by users at work or at home. Further, in the present invention, a sole acupressure device may be integrally formed at the upper end of the arm of the leg with the casserole. This is an embodiment in which a chair manufacturer implements the present invention. Further, a sole acupressure device may be integrally formed on the upper end of the arm of the leg cover attached to the leg with the casserole. This is also an embodiment in which a manufacturer implements the present invention.

FIG. 1 is an explanatory view showing an embodiment of the present invention taking an office chair as an example. In FIG. 1, a chair 10 is provided with a backrest 14 at a rear portion of a seat 12, and a leg 18 at a lower portion of the seat 12 via a column 16 which is adjustable in length. In this embodiment, the leg 18 is provided with five radially arranged leg arms 20, and the lower end of the leg arm 20 is provided with a caster 24. According to the present invention, such an office chair 10 is provided with a sole finger pressing device 26 on the upper end of the arm end of two adjacent leg arms 20 of the leg 18. For example, the same sole 26 as the sole Shiatsu 26A shown in FIG. 2 (A) is worn. That is, the acupressure of the sole in Fig. 2 (A) The tool 26A has a tip spherical part 36a integrally formed on the upper part of the cylindrical main part 34a, and as a fixing part at the lower part of the main part 34a, it is fixed in this embodiment. Screw 38a is formed integrally. As shown in Fig. 1, the tip sphere 36a is pressed against the sole of the user sitting on the chair 10 while being attached to the upper end of the leg arm 20 of the chair 10. In this example, the curvature of the tip spherical portion 36a is, for example, 18 R.

FIGS. 2 (B) and 2 (C) show another embodiment which can be attached to the chair 10 of FIG. 1 and FIG. 2 (C) shows a main body 3 4b, 3 4 with respect to the sole abutment device 26 A of FIG. 2 (A). The height of c is getting lower. On the other hand, the tip spheres 36b and 36c have approximately the same curvature as the tip sphere 36a. The three types of sole acupressure devices 26 A, 26 B, and 26 C shown in FIGS. 2 (A) to (C) with different heights show the finger pressure when pressing the sole in descending order. You will be strongly involved. The sole acupressure devices 26A, 26B, 26B are made by, for example, metal cutting, and the surface is subjected to a waterproofing treatment or a painting treatment as necessary.

FIG. 3 is an explanatory view of a state where the user is pressing the sole of the foot using the chair 10 to which the sole finger pressing device 26 of FIG. 1 is attached. In FIG. 3, the user 28 presses, for example, one foot 32 on the sole of the leg arm of the leg 18 while sitting on the chair 10. Put on. When the foot 32 is placed on the sole shirring device 26 in this manner, the lower side of the user 28 from the knee to the thigh rises from the seat 12 to form a gap 30. By forming the gap 30 in this way, the weight from the thigh to the toe portion is naturally added to the sole finger acupressure device 26, and the user 28 can add the foot 3 2 to the sole acupressure device 26. By putting on the foot, it is possible to receive the finger pressure of the sole finger pressing device 26 on the sole in this natural state without particularly applying pressure to the foot. For this reason, the user 28 can easily adjust the position of the sole of the foot 32 to the sole acupressure device 26 if he / she has a simple knowledge of the parts of the sole that require acupressure. However, it is easy to create a state in which a so-called rub is properly pressed. In FIG. 3, the user 28 has one foot 32 placed on the sole abutment 26, but the leg 18 has two soles 26 on the leg 18 side. It is possible to acupressure both feet at the same time by putting feet on each of them. FIG. 4 is an explanatory view of another embodiment of the chair according to the present invention equipped with a sole acupressure device having a different shape from the embodiment of FIG. In FIG. 4, a chair 10 includes a seat 12 and a backrest 14, and has five radial leg arms 20 on a leg 18 rotatably provided through a support 16 at a lower portion of the seat 12. Two adjoining shiatsu pads with different shapes are attached to two of them.

This sole acupressure device 40 is the same as the sole acupressure device 4OA shown in FIG. 5 (A). In this sole acupressure device 4OA, a tip sphere portion 44a having a smaller curvature than the sole acupressure device 26A in FIG. Has formed. The curvature of the tip spherical portion 44a is, for example, 6R. A fixing screw 46a is formed on the lower part of the main body 42a via a flange 45a. In the sole acupressure device 4OA shown in FIG. 5 (A), the curvature of the tip sphere portion 44a is as small as 6 R, for example, and the curvature of the tip sphere portion 36a in FIG. The finger pressure applied by pressing the sole against the ball tip 4 a when the user puts his foot on the sole acupressure device 4 OA is stronger than the R and the large sole acupressure device 26 A. Become. Therefore, the sole abutment 26 A having a large curvature of the tip sphere 36 a as shown in FIG. 2 (A) can be called a so-called soft type because the finger pressure is low. The one with strong finger pressure due to the small curvature of the distal end ball portion 44a as in A) can be called a so-called hard evening sole acupressure device. FIGS. 5 (B) and 5 (C) show the height of the hard type sole acupressure device 4OA of FIG. 5 (A) gradually reduced. In other words, the curvature of the tip ball portions 44b, 44c in the sole finger presses 40B, 40C is almost the same as the curvature of the tip ball portion 44a in the sole finger press device 4OA in FIG. The same 6R, but the height of the main body portions 42b and 42c is lower than that of the main body portion 42a. The flanges 45b and 45c and the fixing screws 46b and 46c are the same as the flange 45a and the fixing screws 46a in Fig. 5A. In this way, for the hard type shown in Figs. 5 (A) to 5 (C), when the height of the main body is sequentially reduced as shown in the soles 4OA, 4OB and 40C, the finger pressure increases as the height increases. The lower the finger pressure, the weaker the finger pressure. Even with the same hard type, the finger pressure varies depending on the height of the main body. For this reason, in the present invention, three types of soft sole acupressure devices 26 A to 26 C shown in FIG. 2 and a hard type sole acupressure device 40 A to 4 A shown in FIG. 5 are used. 0 C The user may arbitrarily select the required type and attach it to the leg 18 as shown in the chair 10 of FIG. 1 or FIG.

In the sole acupressure device 110 with this structure, the main unit 1 1 2 against the spring 1 1 8 is applied by the force applied when the foot is mounted on the main unit 1 1 2 while attached to a chair. Is pushed into the fixed part 1 14, thereby adjusting the force applied to the foot placed on the main body 1 1 2, thereby causing the main body 1 1 2 to protrude and retract against the spring 1 18, By changing the finger pressure applied to the sole, more effective finger pressure can be performed.

FIG. 19 shows another embodiment of the sole acupressure device to be mounted on the chair of the present invention. This embodiment is characterized in that a heating unit is incorporated. In FIG. 19, the sole pressure device 1 18 has a fixing screw 122 embedded in a synthetic resin main body 120 by composite molding, and is fixed inside the main body 120. An oil chamber 1 2 4 is formed. The oil chamber 124 is filled with insulating oil in a state in which heat sink 126 is incorporated. The oil chamber 124 is sealed with an insulating seal 128, and a signal line from the heat sink 126 is drawn out through the insulating seal 128 and connected to the outside with a connector 130. Signal lines 1 3 8 can be connected. The signal line 1 3 8 is connected to the control box 1 32. The control box 1332 is provided with a battery 1336 and a switch 1334.When the switch 1334 is closed, current flows from the battery 1336 to the oil chamber 1224 in the oil chamber 1224. Then, the main body 120 can be heated by heating the insulating oil. The heater 1 26 incorporated in the oil chamber 124 can generate only a very small amount of heat, for example, a calorific value of a miniature bulb, so that the current flowing from the battery 13 6 is very small. Even so, a sufficiently long usage period can be guaranteed. The heating temperature of the main body 120 by the heater 126 may be about the human body temperature or slightly higher than the human body temperature. It is only necessary to be able to heat to such a degree that it does not feel cold even when the sole is touched when the temperature is low. FIG. 20 is an explanatory view of the state of attachment to the chair of the embodiment of FIG. In FIG. 20, the sole acupressure device 1 18 incorporating the heating structure of FIG. 19 is attached to the upper end of the leg arm 20 of the chair 10, and the control box 13 2 is attached to the leg arm 20. It may be fixed with a velcro or double-sided adhesive tape provided on the back of the box at a position near the support 16 at the root of the box.

The shape of the sole acupressure device to be mounted on the chair according to the present invention is not limited to the above embodiment as long as the shape is suitable for the acupressure of the sole, and may take an appropriate shape. Also, the attachment or formation of the sole acupressure device on the upper end of the leg arm of the chair is not limited to the above-described embodiment, and an appropriate structure can be adopted.

Furthermore, in the above embodiment, the sole of the sole is made of metal, synthetic resin, or a composite structure of metal and synthetic resin, but these structures are also described in the above embodiment. Therefore, any material can be used without limitation. Furthermore, the present invention is not limited to the above-described embodiment, and includes appropriate modifications without impairing the objects and advantages thereof. For example, a chair is not limited to an office chair or a chair with radial legs and arms, and the present invention may be applied to a part where a sole can be placed on a chair or a fixture fixedly arranged around the chair while sitting. It may be in a form that allows the user to wear the sole of the foot.

Specifically, in a horizontal seat of a train, the sole acupressure device used in the present invention is mounted on a footrest plate on which a foot, which is detachably mounted below a front seat, is mounted. It can be used in various ways.

Furthermore, as another embodiment of the sole acupressure tool of the present invention, a vibrator structure may be incorporated. In this case, the vibrator built into the sole acupressure device is activated by power supply from the control box, as in the case of the built-in light source shown in Fig. 19.

Further, as another embodiment of the present invention, a magnet may be provided on the sole acupressure tool so that the magnetic force acts on the sole. In this case, if the sole is made of a magnetic material, the sole itself is magnetized. If the sole acupressure device is made of a non-magnetic material, a granular magnet should be embedded in the ball at the tip of the sole. Industrial potential

As described above, according to the present invention, a foot-sucking device is attached to the upper end of the arm of a leg with a plurality of radially arranged legs, so that the user can sit on a chair at work or the like. If you feel stiff shoulders or swelling of your legs, you can easily acupressure your soles by simply placing your soles on the soles of the soles of the chairs where you are sitting. In particular, when the foot is placed on the sole acupressure device attached to the upper end of the leg arm of the chair, the part of the thigh that is in contact with the seat rises, and the weight of the foot naturally decreases. It is not necessary to consciously press the sole of the foot against the sole of the foot, and the weight of the naturally applied leg gives a nearly ideal pressure on the sole of the foot. If you have a simple knowledge of how to do it, you can do effective shiatsu by putting the appropriate sole on the sole.
