Utility model No. 3162247

As disclosed in Patent Document 1, this type of toothbrush has various configurations that make children and infants want to brush their teeth. However, since the toothbrush itself has an extremely simple structure that only has a grip portion that is held by hand and a brush portion that can be inserted into the mouth, it is said that a toothbrush with a specified character as in Patent Document 1 gets tired. There are challenges.
For this reason, the current situation is that children and toddlers are interested in brushing their teeth, and there is a demand for something with a higher degree of interest so that they will not get tired of brushing their teeth.

An object of the present invention is to provide a highly interesting toothbrush.

The toothbrush according to the present invention is a toothbrush including a main body portion including a grip portion gripped by a finger hand and a brush portion abutting on a tooth, and an accessory part attached to and detachable from a mounting portion provided on the grip portion. The accessory part includes a first part in which the first figure is represented and a second part in which a second figure different from the first figure is represented, and the brush portion is oriented in the first direction. In the first use state of the toothbrush, only one of the first portion or the second portion is visibly provided, and the second toothbrush portion is oriented in the second direction opposite to the first direction. In the state of use, only the other of the first part or the second part is visibly provided.

According to the present invention, it is possible to provide a highly interesting toothbrush.

It is a side view of the toothbrush which is one Embodiment of this invention. It is a front view which looked at the toothbrush shown in FIG. 1 from the front. It is a rear view which looked at the toothbrush shown in FIG. 1 from the rear side. It is an enlarged cross-sectional view of the part along the line AA shown in FIG. It is an enlarged exploded perspective view of the main part of the toothbrush shown in FIG. It is a side view which shows an example of the state in which the toothbrush shown in FIG. 1 is self-supporting.

Hereinafter, a toothbrush according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6.
FIG. 1 is a side view of the toothbrush 1. FIG. 2 is a front view of the toothbrush as viewed from the front, and FIG. 3 is a rear view of the toothbrush as viewed from the rear side. In the following description, regarding the orientation of the toothbrush 1, the side where the flocking 5a is provided is the front side (front side), the opposite side is the back side (back side), and the toothbrush is viewed from the side at right angles to the front and back sides (toothbrush). The side (viewed from the side so that the length of the toothbrush can be seen) is called the side surface side.

As shown in FIG. 1, the toothbrush 1 is roughly classified into a main body portion 2 including a grip portion 4 gripped by a finger hand and a brush portion 5 abutting on a tooth, and a mounting provided on the grip portion 4. It is composed of, for example, an accessory part 10 that can be attached to and detached from the part 3 and imitates a character in the form of a doll.
The details of the accessory part 10 will be described later, but the convex portion 3t provided in the mounting portion 3 of the grip portion 4 is fitted into the concave portion 8 and connected. Further, the accessory part 10 has a form that imitates a character having, for example, a head portion 10H and a body portion 10B. And, in appearance, it has a first part 10F in which the first figure of the front part of the character is expressed, and a second part 10R in which the second figure of the rear part of the character different from the first figure is expressed. There is.

As shown in FIGS. 1 to 3, the grip portion 4 has a handle 4a on the side opposite to the brush portion 5 (left side in the drawing) to be gripped exclusively, a neck 4b on the brush portion 5, and a neck 4b. It has a large-diameter portion having a large width when viewed from the front, between the handle 4a and the handle 4a.
A first locking portion 11 (11a, 11b) and a second locking portion 12 (12a, 12b) are formed in this large diameter portion. More specifically, the first locking portion 11 (11a, 11b) is larger than the other portion of the grip portion 4 so that the thumb can be placed at a position inverted by approximately 180 degrees on the front side and the back side, for example. It is a shape having a circular surface (see FIGS. 2 and 3) in width.

The second locking portion 12 (12a, 12b) is located near the first locking portion 11, that is, the left and right side surfaces intersecting the surface on which the first locking portion 11 (11a, 11b) is formed (FIG. 2 and FIG. 3) are formed by a pair of curved surfaces that bulge away from the axis 4CL of the grip portion 4. The second locking portions 12 (12a, 12b) can be said to have a structure arranged between the first locking portions 11 when viewed from the side surface side (see FIG. 1).

Further, different marks 21 and 22 are attached to the respective surfaces of the first locking portion 11. For example, on the front side, a mark 21 in which a radial line is drawn around a circle in the center is attached, whereas on the back side, a mark 22 in which a star shape is drawn is attached. The marks 21 and 22 indicating the front and back surfaces may be attached by printing, but may be formed as, for example, a convex surface (see FIG. 4) or a concave surface.
Further, the second locking portion 12 (12a, 12b) is provided with a plurality of protrusions 12p. That is, the surface of the second locking portion 12 (12a, 12b) has an uneven shape.

FIG. 4 is an enlarged cross-sectional view of a portion of FIG. 2 along the line AA.
As shown in FIG. 4, the cross-sectional shape of the first locking portion 11 is a concave recess shape on the axis 4CL side of the grip portion 4. Further, the first locking portion 11 is tilted, for example, with an inclination angle (θ) away from the axis 4CL as it approaches the brush portion 5 side.

FIG. 5 is an exploded perspective view showing an exploded state of the grip portion 4 and the accessory component 10.
As shown in FIG. 5, the accessory part 10 includes a concave portion 8 that fits into the convex portion 3t of the mounting portion 3. More specifically, the recess 8 is provided with a first recess 8c on the contact surface 10fs on the lower end side (lower end side in the upper and lower sides of the character) of the accessory 10, and a second recess 8d on the tip end side of the head. Has been done. Both recesses 8c and 8d are communicated with each other by a through hole 8h. Further, the shape of the through hole 8h is the same opening cross-sectional shape from the first recess 8c to the second recess 8d.

Further, the cross-sectional shape of both recesses 8c and 8d is, for example, a substantially semicircular shape including a concave flat surface 8g having a flat end side. On the other hand, the cross-sectional shape of the convex portion 3t is a substantially semicircular shape including a convex side flat surface 3g whose one end side is flat. Further, the concave flat surface 8g is formed so as to coincide with, for example, the first portion 10F in which the first figure of the front part of the character is expressed.

On the other hand, in the grip portion 4, the direction of the convex flat surface 3g is provided so as to coincide with the front side of the main body portion 2. Therefore, in the state where the accessory 10 is attached to the main body 2, that is, the state in which the first concave portion 8c and the convex portion 3t are fitted, the first portion 10F, which is the face side of the character, is on the front side of the main body 2. It can be installed only in the direction in which it comes. Further, as described above, since the first locking portions 11 (11a, 11b) are provided on both the front and back sides of the main body portion 2, they correspond to the front and back sides of the character.

As described above, in the accessory part 10, the first portion 10F at the front portion and the second portion 10R at the rear portion are formed on one surface (front side) and the other surface (back side) of the grip portion 4 on which the first locking portion 11 is formed. It is attached in association with. This is because when using the toothbrush 1, for example, when the state in which the brush portion 5 faces upward is set as the first use state of the toothbrush, only the first part 10F is for the person who is brushing the teeth. Becomes visible. On the contrary, when the state in which the brush portion 5 faces downward in the second direction is set as the second use state of the toothbrush, only the second portion 10R can be visually recognized by the person who is brushing the teeth.

The correspondence between the first direction and the second direction of the toothbrush first used state and the toothbrush second used state referred to here is when the front and back of the mounting direction of the accessory 10 with respect to the grip portion 4 are opposite. The opposite is true. That is, when the orientation due to the fitting structure is reversed, the character's first part 10F is on the top when the toothbrush is in the second use state with the brush portion 5 facing down, and the opposite toothbrush is in the first use state. , The second part 10R of the character is on top.

Further, the first use state of the toothbrush and the second use state of the toothbrush referred to here are not limited to the vertical orientation of the brush portion 5, and may be set as a left-right lateral orientation state in which the brush portion 5 faces sideways.

Further, as shown in FIG. 5, the accessory part 10 has a substantially circular cross-sectional shape centered on the axis 10CL penetrating the head portion 10H and the body portion 10B. That is, the outer surface shape is substantially circular. Further, the outer diameter dimensions of the head portion 10H and the body portion 10B may be the same, but it is preferable that the outer diameter dimensions of the head portion 10H are larger.

Further, the contact surface 10fs of the accessory 10 is formed on a flat surface substantially orthogonal to the axis 10CL. On the other hand, the contact surface 4fs on the grip portion 4 side is also formed on a flat surface substantially orthogonal to the axis 4CL. Therefore, the adhesion between the accessory component 10 and the grip portion 4 is good when both the contact surfaces 10fs and 4fs are in contact with each other. As a result, the outer peripheral surface 4s of the grip portion 4 and the outer peripheral surface 10s of the accessory 10 are formed into substantially continuous curves so that the contours of the appearance are integrally (see FIGS. 1 to 3).

As described above, the accessory part 10 is configured such that the body portion 10B forms a part of the grip portion 4 when the accessory part 10 is mounted on the mounting portion 3. As a result, when the toothbrush 1 is gripped, the body portion 10B and the grip portion 4 can be gripped at the same time without any discomfort.

Further, the accessory part 10 has a maximum width D1 in which the head portion 10H has the largest size, as shown in FIG. 2, for example, in front view. The maximum width D1 of the head portion 10H is configured to be larger than, for example, the width of the first locking portion 11 provided on the grip portion 4, that is, the maximum width D2 of the grip portion. As described above, since the head 10H is configured to be large, the head 10H can form a hook while brushing teeth or holding the toothbrush 1.

FIG. 6 is a side view showing an example of a state in which the toothbrush is self-supporting.
Since the second recess 8d is also provided on the head 10H of the accessory part 10, the main body 2 can be connected to the head 10H. Then, when the accessory part 10 is attached to the grip portion 4 from the head portion 10H, the toothbrush 1 can be placed independently as shown in FIG.

As described above, according to the toothbrush 1 of the present embodiment, since the accessory part 10 can be detachably provided on the grip portion 4 of the toothbrush 1, a plurality of types of accessory parts 10 can be attached and detached, and the toothbrush 1 has a change. Can be done. Further, the accessory part 10 is provided with a first part 10F (front side) and a second part 10R (back side) having different shapes, and the first part 10F and the second part 10F and the second part are provided depending on the first use state of the toothbrush or the second use form of the toothbrush. Part 10R can be viewed while selectively brushing teeth. As a result, how to hold the toothbrush 1 can be understood from the orientation of the character, which is the accessory part 10. In addition, while brushing teeth, it can be enjoyed at the first part 10F (front side) or the second part 10R (back side). As a result, it is possible to provide a highly interesting toothbrush.

Further, in the toothbrush 1 of the present embodiment, the accessory 10 has a fitting shape that can be mounted only in a predetermined direction with respect to the mounting portion 3, so that the orientation of the accessory 10 with respect to the grip portion 4 can be specified. Will be done. Therefore, the orientations of the first portion 10F and the second portion 10R of the accessory part 10 in the usage state of the toothbrush 1 can be specified and associated with each other. As a result, the orientation of the toothbrush 1 can be immediately known from the orientation of the accessory 10 (front and back of the character).

Further, in the toothbrush 1 of the present embodiment, the outer peripheral surface 4s of the grip portion 4 and the outer peripheral surface 10s of the accessory component 10 are configured to be connected in a state where the contact surface 4fs and 10 fs of the mounting portion 3 and the accessory component 10 are in contact with each other. Will be done. As a result, the appearance continuity between the grip portion 4 and the accessory component 10 can be improved, and the toothbrush 1 having a sense of unity between the accessory component 10 and the main body portion 2 can be provided.

Further, as described above, according to the configuration in which the grip portion 4 and the accessory component 10 are more experienced, the accessory component 10 can be used as a part of the grip portion 4. Therefore, for example, by making the accessory part 10 larger (longer), the grip portion 4 can be made smaller, and the toothbrush 1 can be made more compact.

Further, in the toothbrush 1 of the present embodiment, the maximum width D1 of the head portion 10H is larger than the maximum width D2 of the grip portion 4, so that one end side of the grip portion 4 is large in the mounted state of the accessory part 10. It has a diameter that makes it easy to hold and can prevent the toothbrush 1 from falling.

Further, in the toothbrush 1 of the present embodiment, the accessory 10 has a substantially circular cross-sectional shape centered on the axis 10CL penetrating the vertical direction of the character, so that the outer peripheral surface 10s is substantially circular. As a result, when the accessory part 10 is placed horizontally on the mounting surface, it can be rolled and played. For example, when the outer diameter of the body portion 10B is smaller than that of the head portion 10H, the movement is such that the body portion 10B not only rolls but also revolves at the same time as the rotation (the direction of the axis line 10CL is set to the turning radius). It can also be operated), and it can enhance the interest.

Further, in the toothbrush 1 of the present embodiment, the accessory part 10 is provided with a contact surface 10fs formed of a flat surface substantially orthogonal to the axis 10CL, so that the toothbrush 1 is mounted independently on the mounting surface. It can be enjoyed as a figurine.

Further, since the contact surface 10 fs is flat, the toothbrush 1 can be erected independently (see FIG. 6) as if leaning forward, but the head 10H is also provided with a second recess 8d. By being done, the character can be placed upside down. That is, a virtual flat surface is formed by the second recess 8d opened in the head 10H, and this can be used as a mounting surface.

Further, in the toothbrush 1 of the present embodiment, since the accessory part 10 is formed with a through hole 8h communicating with the recess 8, the recess 8 has a well-ventilated structure, and is easy to clean and hygienic. Is.

Further, in the present embodiment, since the through hole 8h is formed to have the same shape as the opening cross-sectional shape of the concave portion 8, the length of the convex portion 3t can be increased up to the total length of the accessory part 10. It will be possible. As a result, the engagement depth of the concave-convex engagement can be increased, and the accessory component 10 can be securely locked. Further, since the uneven fitting only needs to match the cross-sectional shape, the fitting depth of the convex portion 3t is not limited, and it is possible to provide the toothbrush 1 which is easy to attach various characters and has high versatility.

Further, in the toothbrush 1 of the present embodiment, the recess 8 has a first recess 8c provided in the body portion 10B and a second recess 8d provided in the head portion 10H, so that the connection with the main body portion 2 is a character. It is possible from either the top or bottom of the character, and you can enjoy the change in the mounting form of the character.

Further, in the toothbrush 1 of the present embodiment, the grip portion 4 is provided with the first locking portion 11 having a side width larger than that of the other portions, so that when brushing teeth, the fingertips such as the thumb are first. It can be used by hitting the locking portion 11. As a result, even a weak child or toddler can easily apply force to the toothbrush 1, and the usability is improved.

Further, since the first locking portion 11 is formed on both the front and back sides of the grip portion 4 (positions inverted by 180 degrees), for example, the first locking portion 11 can be used in any of the up and down directions of the toothbrush 1. , It is also possible to touch a finger other than the thumb. Further, it is also possible to hold the first locking portion 11 with the thumb and other fingers at the same time so as to sandwich the toothbrush 1, and the usage pattern of the toothbrush 1 can be remarkably diversified.

Further, in the toothbrush 1 of the present embodiment, since the first locking portion 11 has a recessed shape, it can be easily held by being familiar with the shape of the tip of the fingertip. Further, the first locking portion 11 is tilted away from the axis 4CL of the grip portion 4 as it approaches the brush portion 5, that is, the surface of the first locking portion 11 is the grip portion 4. By inclining (inclination angle θ) toward one end side (opposite side of the brush portion 5), it is possible to correspond to the curved shape of the tip of the thumb of the hand holding the grip portion 4. As a result, it is possible to easily apply force to the fingertips.

Further, in the toothbrush 1 of the present embodiment, the accessory 10 has the first portion 10F (front side) and the second portion 10R (back side) on the front side and the back side of the grip portion 4 in which the first locking portion 11 is formed. Attached in association with the corresponding orientation. Thereby, the first usage state of the toothbrush and the second usage state of the toothbrush can be associated with the orientation of the first locking portion 11, and for example, the use of the first locking portion 11 can be promoted according to the orientation of the character. It can be used as a part for learning how to use the toothbrush 1.

Further, in the toothbrush 1 of the present embodiment, different marks 21 and 22 are attached to the surfaces of the first locking portions 11 on the front and back sides, so that the first usage state of the toothbrush and the second usage state of the toothbrush are marked with this mark. It can be associated with 21.22. Further, when the marks 21 and 22 are formed in a concavo-convex shape, it is possible to improve the catching of the fingertips and improve the ease of holding.

Further, in the toothbrush 1 of the present embodiment, since the second locking portion 12 having a different shape is provided in the vicinity of the first locking portion 11, the options for how to touch and grip the finger hand are increased. It can be used for a wide range of hand sizes.

Further, in the toothbrush 1 of the present embodiment, the second locking portion 12 is composed of a surface that intersects the surface of the first locking portion 11 between the first locking portions 11 in the side view of the toothbrush 1. Since the grip portion 4 is formed at substantially the same position as the first locking portion 11 in the longitudinal direction, both the locking portions 11 and 12 can be formed in a compact portion, and both the locking portions 11 and 12 can be formed with small fingertips. You can easily hold or change hands at the same time.

Further, in the toothbrush 1 of the present embodiment, since the second locking portion 12 is formed by a curved surface that swells away from the axis 4CL of the grip portion 4, the toothbrush 1 is used so as to be picked by, for example, a fingertip. When doing so, the contact surface with the fingertip can be made smaller. As a result, it is easy to correspond to the usage pattern such as when the brush portion 5 is to be applied softly to the teeth.

Further, since the second locking portion 12 is a bulging curved surface, the contact surface with the fingertip becomes small, but the protrusion 12p (see FIGS. 2 and 3) is formed on the curved surface. Even when you hold it lightly with your fingertips, you can increase the friction with your fingertips and make it easier to hold.

Although one embodiment of the present invention has been described above, the present invention can be appropriately modified within the scope of the technical idea. For example, in the above embodiment, the convex portion 3t and the concave portion 8 of the mounting portion 3 to be mounted in a predetermined direction have a cross-sectional shape having a straight portion and an arc portion. The present invention is not limited to this, and other triangular shapes and rectangles can be adopted. For example, in the case of a triangular shape, when it is an equilateral triangle, the orientation of the accessory 10 can be selected in three directions. Further, in the case of a square or a regular polygon, the orientation can be selected for the number of angles.

Further, in the above embodiment, the grip portion 4 is provided with the convex portion 3t, and the accessory component 10 is provided with the concave portion 8. However, the concave-convex relationship may be reversed. Further, although the recess 8 is configured to penetrate the accessory part 10, the recess 8 does not have to communicate with the through hole 8h.

Further, in the above embodiment, the recess 8 is provided on the upper end side of the character's head 10H and the lower end side of the body portion 10B, but the recess 8 may be provided on the side surface of the character. ..

Further, in the above embodiment, the first locking portion 11 is provided on both the front and back sides of the grip portion 4, but the first locking portion 11 may be provided only on one side. Further, the first locking portion 11 does not have to have a recessed shape.
Further, in the above embodiment, the first locking portion 11 is provided at a position inverted by 180 degrees on both the front and back sides, but the front and back surfaces of the grip portion 4 are not inverted by 180 degrees and are slightly tilted (the grip portion 4).
