Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a multipurpose toothbrush that can effectively perform toothbrushing operations, and more specifically to a toothbrush with detachable accessories for oral care such as interdental cleaning. It is something.

[Prior art]

In general, if your teeth are not brushed properly, you will not be able to clean them well even with a toothbrush, so various accessories such as tuft brushes, stamulators, dental picks, interdental brushes, and mirrors for checking cleaning are used as interdental cleaning tools. It is known to provide these parts at the tail end of a toothbrush.

[Problem that the invention attempts to solve]

For example, a floss handle is overlapped with a toothbrush handle so that it can be fitted using the jointed uneven parts (Jetkaisho).
52-150467), those connected to the end of the toothbrush handle with a plug-in connection structure (Japanese Utility Model Publication No. 56-101031), and those with a mirror attached to the end of the toothbrush handle with a shaft or hinge so that it can be rotated and stored freely. (Utility Model Application Publication No. 53-131862) etc. have been proposed.

However, if these attached parts are integrated, it will be difficult to perform toothbrushing operations, and if a storage compartment is created, it will take up a lot of storage space, and if they are removable, it will not only be complicated to connect and disconnect them, but it will also be difficult to properly maintain the connected state. In any case, there were problems in handling, such as not being able to do so, which caused trouble in cleaning operations, and on the other hand, if the connection was strengthened, it would be difficult to fit and remove, making it difficult to handle.

The present invention aims to eliminate these conventional drawbacks, and allows for appropriate and easy toothbrushing operations and other operations necessary for tooth cleaning, such as interdental cleaning, as well as reliable and stable toothbrushing for attachment and detachment of accessory parts. The object of the present invention is to provide a toothbrush that is easy to operate and handle.

[Means for solving problems]

The present invention provides a toothbrush having a handle B with a flocked part A and an oral care accessory C attached to the tail end of the handle, in which a through hole 1 is provided in the handle B, and the through hole The protrusion 2 to be fitted into the arm 5
is provided on the attached part C via the protrusion 2.
A recessed surface 3 that can be operated by pressing contact is provided on the handle part B so as to be concave from the surface of the handle part B so that the end of the protruding part 2 of the attached part C is exposed, and the end of the protruding part 2 This toothbrush is provided with a fixing part 4 for locking so that the toothbrush does not protrude from the surface of the handle part B.

〔Example〕

An example of the present invention will be explained with reference to Figs. 1 to 4.
A protrusion 2 formed at the end of the arm 5 of the accessory part C for oral cavity management is removably provided in the through hole 1 formed at the tail end of the handle B where the flocked part A is located. A recessed surface 3 that can be operated by pressing contact is formed on the handle part B so that it is concave than the surface of the handle part B so that the protruding part 2 of the attached part C is exposed, and a fixing device for locking is provided on both fitting surfaces. The toothbrush handle part B in which the part 4 is provided and the accessory part C are detachable.

One end of the through hole 1 opens into a recessed surface 3 formed in the handle B, and the other end is continuous with a recessed groove 6 into which the arm 5 of the attached part C fits,
The other end of the groove 6 is open to the end surface of the handle B.

The end of the fitting protrusion 2 of the attached part C is exposed from the recessed surface 3 when connected to the handle B, and
The fixing portion 4 is formed as a flange-like convex portion at the end of the protruding portion 2, and the protruding portion 2 is located in the recessed surface 3. It functions effectively as a pressing part when uncoupling. In this embodiment, in which the mirror 7 is used as the accessory part C, the arm 5 has an axis along the handle B.
A mirror 7 is provided by metal vapor deposition or other appropriate means in a state where it is tilted at a predetermined angle.

By fitting the arm 5 into the groove 6, the axial center of the arm 5 and the axial center of the handle B are brought close to each other without sacrificing strength.

The through hole 1 is formed with an inclined surface so that the side of the recessed surface 3 is smaller, and the protrusion 2 that comes into contact with the wall surface
The wall surface is formed in a shape along the wall surface.

Further, at least the peripheral part of the through hole 1 and/or the protruding part 2 are formed of an elastic member, and even if the fixing part 4 protrudes, it can be inserted, but the through hole 1 in which the fixing part 4 slides is formed into a tapered surface that is slightly widened only on the insertion side of the fixing part to facilitate insertion of the protruding part 2 from which the fixing part 4 protrudes. Note that if the fixing part 4 is made retractable, the insertion can be further facilitated.

On both sides of the protruding part 2, the central part has a bulged shape and firmly abuts on the through hole 1 at this part, and when the arm 5 abuts on the bottom surface of the groove 6, the fixing part 4 The attachment part C is arranged so that its base is locked to the edge of the through hole 1, and the fixing part 4 prevents it from coming off. It is designed to maintain a firmly and accurately connected state to part B.

In the examples in Figures 5 and 6, the fixing part 4 is attached to the attached part C.
It is composed of a convex part provided at the center of the surface that comes into contact with the through hole 1, and a concave part that fits into the convex part, and it goes without saying that the concave and convex parts may be provided in a relative relationship. do not have.

In the example shown in FIG. 7, the protruding portion 2 provided on the arm 5 is formed into a truncated quadrangular pyramid shape with the center portions of both sides constricted and the end surface being the largest portion.

In the examples shown in Figs. 8 and 9, a tufted brush for interdental cleaning is provided as accessory part C, and in addition to this, a stamulator, interdental brush,
A dental pick, a hair transplant part different from the hair transplant part A, etc. are used.

The specific example shown in FIG. 10 is an example in which a protrusion 2 is provided at the end of the toothbrush handle B, and a through hole 1 is provided in the attached part C, and it is sufficient to provide the protrusion 2 relatively as a connecting part. It is.

Furthermore, as long as the positional relationship between the recessed surface 3 and the end of the protrusion 2 is maintained as described above, the connection angle between the handle part B and the attached part C can be adjusted by forming the connection part as a rotatable pivot part so as to be detachable. It can be changed, and in that case, it is better to provide a stopper that can be fixed at any rotational position.

Note that the protruding portion 2 may be provided with a locking mechanism such as a sliding type or a bending type to further improve the connection state.

[Effect of idea]

With this invention, the toothbrush and the attached parts can be easily and precisely attached, and since the protruding part does not protrude from the other surface, there is no chance of accidentally pushing the protruding part and breaking the connection, and the connection with the attached parts is prevented. When removing the toothbrush, it is easy to push out and press the protrusion exposed inside the recess as it mixes with the recessed surface, making it easy to remove the fitted state, making it a conveniently used toothbrush, and it is useful as an oral cleaning tool with attached parts. This has the following effects.
