2. Description of the Related Art Conventionally, oral cleansing tools such as toothbrush, interdental brush, dental floss, tarnishing tool, tongue brush, toothpaste and dental mirror have been used to clean the oral cavity after eating and before going to bed. It has been common to clean teeth and tongue by using it, but with the increasing awareness of oral hygiene in recent years, many people should use a combination of various types of oral cleaning tools adapted to various cleaning methods. It's coming.

Further, since there are various places where the oral cleaner is used not only at home or office, but also at travel destinations and business trip destinations, there is a strong demand for an oral cleaner having excellent portability, and portability and operability are required. In consideration of the above, various forms of combined oral cleaning devices have been proposed.

For example, the oral hygiene set disclosed in Japanese Patent Laid-Open No. 232546/1984 is provided with a shaft-shaped handle and a plurality of different types of oral hygiene tools, and the different types of oral hygiene are provided at the tip of the handle. Select any one of the accessories and attach it detachably in a compatible manner with other oral hygiene equipment. Different oral hygiene equipment can be used with one handle for easy handling, and the set fits compactly. Therefore, it is convenient to carry and store.

Further, the above-mentioned publication describes that a bent spacer is interposed between the handle and the interdental brush in consideration of operability. Furthermore, Japanese Patent No. 274965
A toothbrush having an interdental device disclosed in Japanese Patent No. 5 is a toothbrush having a handle and an interdental device rotatably attached to the handle, the device having a first position and a second position. Rotatably mounted about a shaft movable between positions and locating means are provided, the shaft being the first.
It is described that when in the position, it holds the position in a predetermined orientation and allows movement of the device when the shaft is in the second position.

[0006]

However, in the structure in which different types of cleaning units are used in one handle such as the above-mentioned oral hygiene set, the unused cleaning unit is not attached to the handle. In other words, it is not convenient for carrying and storing because it is in a disjointed state. Furthermore, since the cleaning unit may be lost, a storage case or the like is additionally required to avoid it, and it tends to lack portability.

Further, when several different types of cleaning sections are used in order, for example, when a toothbrush is applied with a toothpaste to clean the teeth and then an interdental brush is used, the toothbrush is removed from the handle and the teeth are removed. An inter-brush must be attached to the handle. At this time, the cleaning part is directly touched, which is not preferable in terms of hygiene, and it may take time to replace the cleaning part. Further, if a place for placing the toothpaste or the removed toothbrush is not secured, the surroundings become cluttered and cleaning is difficult.

On the other hand, in consideration of operability, an angle is provided between the cleaning portion and the shaft body like the bending spacer in the oral hygiene set described above and the interdental device in the toothbrush having the interdental device described above. Even if it is designed to be used, the angle is fixed, or at most it is a rotation angle on one axis, so it is not always possible to obtain preferable operability, fatigue of hands and arms, cleaning of the oral cavity in every corner It was difficult to do.

The present invention has been made in view of the above problems, and makes it possible to easily change the type of the cleaning unit according to the cleaning method, and to combine various cleaning units so that the portability is improved.

In order to achieve the above object, an oral cleaning tool and a set thereof according to the present invention are an oral cleaning tool comprising a shaft and a cleaning section provided at one end of the shaft. The shaft body is provided with an opening at the other end of the cleaning portion to form a hollow portion, a first connecting means provided on the opening portion side, and a second connecting means provided on the cleaning portion side. The first feature is that the connecting means is provided. Further, a plurality of oral hygiene tools having such characteristics are provided, and a cleaning part of another oral hygiene tool can be inserted into and removed from the opening so as to be accommodated in the hollow part, and the first connecting means. The second feature is that the second connecting means included in another oral cleaning tool can be connected.

In the above construction, the cleaning portion provided at one end of the shaft body includes a toothbrush, an interdental brush, a dental floss, a tar remover, a tongue brush, a dentifrice, a dental mirror, etc., depending on the cleaning method. To be In addition, it is preferable that the size of these cleaning units is set to the minimum necessary size in consideration of portability, without impairing the cleaning function. When the cleaning unit is detachably fixed to the shaft body, the toothbrush and the dentifrice can be easily replaced when the toothbrush or the like is worn or the dentifrice is used up.

In order to insert the cleaning section into the hollow portion by inserting it from the opening of another oral cleaning tool, it is necessary to determine the size of each cleaning section according to the size of the cleaning section. That is, with respect to the size of the cleaning unit determined in the above range, the cross-sectional shape and the cross-sectional area of the opening are determined to be larger than that of the cleaning unit, and then the length and volume of the hollow portion are larger than those of the cleaning unit. It should be decided so that The size of the cleaning unit is the largest of the cleaning units used. Generally, the size of the toothbrush is the maximum, so it is preferable to use it as a reference, but it is not limited to this if there are other types of large ones.

Once the size and shape of the opening and hollow are determined, the size and shape of the shaft can be determined. However, the shape of the inner surface does not need to be a cylindrical shape or a polygonal cylinder shape as long as the cleaning unit provided in another oral cleaning tool can be housed in the hollow portion of the shaft body, and it is a free-form curve including a straight line. A cylindrical shape having a configured cross-sectional shape may be used. Further, there is no restriction on the size of the shaft body, but in consideration of portability, it is preferable to keep the wall thickness of the shaft body to the necessary minimum. Further, the inner surface shape and the outer surface shape do not have to be similar. Considering the general size of the cleaning unit and the portability of the oral cleaning tool, the size of the cross section of the shaft body is preferably within a circle with a diameter of about 20 to 30 mm, and the wall thickness is preferably about 5 mm or less. Also, the length is preferably about 30 to 60 mm. In addition, if the shaft body is provided with a ventilation hole or the like, the cleaning portion after use is easily dried, which is preferable in terms of hygiene.

The first connecting means and the second connecting means provided on both sides of the shaft are not particularly limited as long as they can be connected, but a load is applied to the connecting portion during cleaning. It is desirable to have a structure that can withstand even if added. For example, if the connecting portion of the shaft body is cylindrical, one of the inner surface of the shaft body on the opening side or the outer surface of the shaft body on the cleaning portion side is provided with a spiral protrusion and the other is provided with a spiral groove to enable screwing. The structure can be mentioned. In addition, an annular protrusion is provided on one side,
A structure in which an annular concave portion is provided on the other side for fitting, or a structure in which a protrusion is provided on one side and a keyway is provided on the other side for screwing may be used. Even when the connecting portion of the shaft body is not cylindrical, a structure is provided in which one side is provided with a circumferential convex portion and the other side is provided with a circumferential concave portion, and one side is provided with a pin-like projection supported by an elastic body, Examples include a structure in which a hole for receiving a projection is provided on the other side for fitting, and a structure in which a key-like hook is provided on one side and a projection for receiving a hook is provided on the other side for hooking.

Furthermore, when there are two or more oral cavity cleaners, the cleaning section of the second oral cavity cleaner is inserted from the opening of the first oral cavity cleaner and is housed in the hollow part to clean the first oral cavity cleaner. The first connecting means of the device and the second connecting means of the second oral cleaning device can be connected. By repeating this for the third and subsequent oral cavity cleaners, an arbitrary number of oral cavity cleaners can be integrally connected.

For example, a method of using the oral cleaning tool in a state where the cap portion and the two oral cleaning tools are connected and integrated will be described. First, when the cap portion is removed, the cleaning portion of the first oral cleaning tool is taken out, so that the cleaning portion is used. Next, the connection between the first and second oral cleaners is removed, the cleaning section of the first oral cleaner is inserted from the opening of the second oral cleaner, and is housed in the hollow part. Then, the first connecting means of the second oral cleaning tool is connected to the second connecting means of the first oral cleaning tool. Then, the cleaning part of the second oral cleaning tool is taken out, so that cleaning part is used. After cleaning, insert the cleaning part of the second oral cleaning tool through the opening of the cap part,
The first connecting means of the cap portion is housed in the hollow portion, and 2
The second connecting means of the oral cavity cleaning tool is connected, the cap portion is attached, and they are integrated again.

According to the above construction, since the cap portion and the shaft body do not cover the cleaning portion and there is no need to consider hygiene such as dirt, it is easy to carry and highly portable. Of course, since different oral cleaning tools can be connected, it is possible to combine an arbitrary number of different oral cleaning tools with different cleaning units to provide multi-functionality. In addition, when using it, it is not only easy to replace it because it is only necessary to replace the oral cleaners in order and connect them, but also because the shaft can be replaced, it is hygienic without touching the cleaning part directly. is there. Furthermore, since it is always integrated during use, there is no need to secure a place for the removed cleaning unit, and it is convenient because it can be integrated when carrying or storing.

Although not included in the configuration of the cap portion described in the third feature, the same means as the second connecting means in the configuration of the shaft body described in the first and second features described above is used. It may be provided on the other side of the cap opening. With this configuration, when the cap portion is removed, the second connecting means of the cap portion and the first connecting means of the shaft body can be connected to each other. It is not necessary to secure.

Further, in addition to the above-mentioned first to third characteristics, in the oral cleaning tool and the set thereof according to the present invention, the shaft body has a grip portion having an opening at one end to form a hollow portion, The gripping part comprises a first connecting means provided on the side of the opening and a first coupling means provided on the other side, and the movable part is a movable part having a cleaning part at one end. A second connecting unit provided on the cleaning unit side and a second connecting unit provided on the other side are provided, and the first connecting unit and the second connecting unit are connected to each other in a variable angle. This is the fourth feature.

In the above structure, the opening, the hollow part and the first connecting means of the gripping part and the cleaning part and the second connecting means of the movable part are the same as the above-mentioned first and second connecting parts. It is the same as each configuration in the second feature.

The gripping part and the movable part are connected by the first connecting means and the second connecting means provided respectively, but the means are not particularly limited as long as the angle is variable. However, it is preferable that the structure has a strength that can withstand the load applied to the coupling portion during cleaning and that the direction of the cleaning portion can be changed to a direction suitable for the cleaning operation. For example, there is a structure in which a spherical concave portion is formed on one of the one end of the grip portion or the movable portion and a spherical convex portion that fits with the spherical concave portion is formed on the other and the spherical concave portion is fitted. At this time, it is effective to make the fitting surface tight and to make the surface uneven so that the resistance is not changed even if a load is applied during cleaning. Also,
A high resistance material may be enclosed in the clearance between the fitting surfaces to increase the resistance.

According to the above construction, since the cleaning portion can be adjusted to the angle and direction that is most easy to clean, preferable operability can be obtained even if the grip portion is also held, and fatigue of the hand or arm can be reduced. Instead, it will be easier to clean every corner of the mouth.

Next, an oral cleaner according to a second embodiment of the present invention is shown in FIGS. 5 to 9 and the details thereof will be described below.

The oral cleaner of Example 2 is also the same as that of Example 1 described above.
Similarly to the above, it is a cylindrical shape in which the cap 10 and the toothbrush 20, the interdental brush 30, the dental floss 40, and the dentifrice 50, which are individual oral cleaners, are combined. The separated state is shown in FIG. 5, and the stored state is shown in FIG. Note that the cap 10 and the dentifrice 50 have the same configurations and operational effects as those of the first embodiment, and therefore description thereof will be omitted.

In the toothbrush 20, the interdental brush 30 and the dental floss 40 having other configurations, the shaft body 1 is divided into a grip portion 1a and a movable portion 1b. Gripping part 1a
The opening 3 is provided at one end of the
A screw hole 5 is provided on the inner peripheral surface of the and the spherical concave portion 100 is formed at the other end. Further, the spherical convex portion 101 that can be fitted into the spherical concave portion 100 is supported by the support shaft 102, and the movable portion 1
It is formed at one end of b, the thread 6 is provided on the outer peripheral surface of the other end of the movable portion 1b, and the cleaning portion 2 is provided on the center side of the thread 6. Then, the spherical concave portion 100 and the spherical convex portion 101 are fitted to join the gripping portion 1a and the movable portion 1b in a variable angle, and the rubber packing 103 is sandwiched between the fitting surfaces. It should be noted that, in the above-described configuration, the opening 3, the hollow portion 4, the screw hole 5, the screw thread 6, and the cleaning unit 2 have the same configurations and operational effects as those of the first embodiment, and therefore description thereof will be omitted. Further, FIG. 7 is an enlarged view showing the structure of the connecting portion.

In the above structure, the spherical concave portion 100 has a diameter D of 11 mm, and the spherical convex portion 101 has a diameter d of 10 mm.
The thickness t of the support shaft 102 is 2 mm. Since the gap between the mating surfaces of the spherical concave portion 100 and the spherical convex portion 101 is 0.5 mm in radius, the thickness of the rubber packing 103 made of silicon is set to a little over 0.5 mm so that the fitting surface is pressed. ing. In addition, since the total length of the shaft body 1 including the grip portion 1a and the movable portion 1b is about 66 mm, the total length of all of them is 237 mm.

On the other hand, the size of the opening of the spherical concave portion 100 fitted with the spherical convex portion 101 is related to the movable angle θ of the movable portion 1b. Further, in order to prevent the spherical convex portion 101 from coming off the spherical concave portion 100 when an overload is applied to the coupling portion during cleaning or the rubber packing 103 is removed from the spherical convex portion 101, the spherical convex portion 101 is movable within a range where the following formula is satisfied. The movable angle θ of the portion 1b is determined. For example, assuming that the movable angle θ of the movable portion 1b is 90 °, it is substituted into the following equation together with other numerical values.
Then, the left side becomes 5, and the right side becomes about 4.27, so that the equation is established.

D / 2> (D / 2) sin (φ + θ / 2) where φ = sin ⁻¹ (t / D)

That is, in the second embodiment, the movable portion 1b can be adjusted with respect to the grip portion 1a at the central angle of 90 °. Further, since the coupling portion is fitted with a spherical surface, not only the angle of the movable portion 1b with respect to the grip portion 1a but also the rotation, that is, the orientation of the cleaning portion 2 can be adjusted. Further, since the silicone rubber 103 having a high surface friction coefficient is sandwiched between the fitting surfaces while being pressed, the orientation does not easily change even if a load is applied during cleaning. FIG. 8 shows a variable state of the angle and the direction in the example of the toothbrush.

In the case where there is one connecting portion as described above, the angle of the movable portion 1b with respect to the gripping portion 1a was adjusted within a central angle of 90 °, but in the second embodiment, an oral cleaning tool provided with the connecting portion. Since three are combined and there are three connecting portions, the angle can be adjusted within the central angle of 270 °. Figure 9
In the case where the toothbrush 20 and the interdental brush 30 are combined and there are two connecting portions, the toothbrush 20
It showed that the angle and the direction of was changed.

This is because the interdental brush portion 32 is connected to the toothbrush 20.
Of the toothbrush 20 and the screw thread 5 of the interdental brush 30 are screwed together, and the grip portion 1a of the toothbrush 20 and the interdental brush 30 are inserted. The movable part 1b is integrated into two parts, the connecting part of the toothbrush 20 and the connecting part of the interdental brush 30. The cap 10 and the dental floss 4 are shown in the figure.
0 and the dentifrice 50 are not shown, but they are appropriately screwed together and integrated in actual use.

When brushing teeth with the toothbrush portion 22, the movable portion 1b of the toothbrush 20 has a central angle of 90 with respect to the holding portion 1a.
If the angle is within °, cleaning can be performed with the gripping portion 1a of the toothbrush 20 at the same angle, but if it is 90 to 180 °, the gripping portion 1a of the interdental brush 30 can be held at the same angle for cleaning.

According to this structure, the angle and direction of the cleaning unit 2 with respect to the grip 1a can be adjusted to the position where it is most easily cleaned. Therefore, even if the grip 1a is held in the same manner, the most preferable operation for each person. Not only does it reduce the fatigue of the hands and arms, but also makes it easier to clean the inside of the mouth.
