[0344] In the embodiment described in FIG. 54, the technical idea of ​​the present invention is applied to a general toothbrush. However, it goes without saying that it can also be applied to molar toothbrushes.

[0345] The first elastic rotation restoring portion 452 is a first portion extending from the toothbrush head portion 410. The handle 420 includes a first protrusion 452a and a second protrusion 452b extending from the handle 420. The first protrusion 452a and the second protrusion 452b are rotatable relative to each other around an axis in the longitudinal direction of the toothbrush. Here, the term "relatively rotatable" means that the first protrusion 452a can be rotated in the longitudinal direction. This means that the longitudinal axis of the second protrusion 452b is not rotated in conjunction with the longitudinal axis rotation. do.

[0346] For this purpose, the first protrusion 452a is inserted into the hollow of the second protrusion 452b in the longitudinal direction, as shown in FIG.

[0347] Also, a hole is provided in the first elastic rotation restoration part 452. This is explained in FIG. Also, as in the example explained in Figure 49, if at least one hole The second elastic rotation restoring portion can provide a restoring force after being compressed and deformed. A torsional deformation occurs when the crosspiece is twisted around the longitudinal axis, and the torsional elastic energy It is possible to store and release

[0348] A second elastic rotation restoration portion 454 is provided on the surface of the first elastic rotation restoration portion 452. The second elastic rotation restoring portion 454 has one end and the other end connected to one end of the toothbrush head portion 410. It surrounds at least a portion of the handle portion 420 and at least a portion of one end of the handle portion 420.

[0349] On the other hand, the recess or hole is formed on the outer side of the second elastic rotation restoration portion 454, not on the inner side. It is also possible to do so.

[0350] According to one example, the outer surface of the first elastic rotation restoration part 452 and the outer surface of the second elastic rotation restoration part A sleeve (not shown) is provided between the inner surfaces of the first and second axial members 454. The shape surrounds at least a part of the elastic rotation restoring portion 452 in the circumferential direction.

[2] The first protrusion 452a and the second protrusion 45 When 2b is assembled, the rigidity is ensured and it is not accidentally pressed when brushing teeth. The elephant can be minimized.

[0353] In this embodiment, the first elastic rotation restoring portion 452 is a first protrusion 452a extending from the handle portion 420; and a second protrusion 452b extending from the handle portion 420. However, the toothbrush head 410 and the handle 420 are not necessarily connected to each other. Any structure that allows relative rotation of the two is possible.

[0354] For example, as shown in FIG. 54, a toothbrush head 410 includes a first protruding portion 412 extending from the toothbrush head 410. The handle portion 420 has a first protrusion 452a therein. In this case, unlike FIG. 54, the second protrusion 45 2b can be omitted.

[0355] For example, as shown in FIG. 54, a second protrusion extending from the handle portion 420 The toothbrush head portion 410 has the second protrusion 452b therein. In this case, the first protrusion 452a may be omitted. can be done.

[0356] According to one example, an opening is provided on one side of the handle portion 420, and the first protrusion 452a passes through the second protrusion 452b and is exposed through the opening in the handle portion 420. Therefore, the user can press the exposed first protrusion 452a. This allows the user to rotate the toothbrush head 410 or not. When the user desires to brush his teeth, he does not press the exposed first protrusion 452a but instead presses the roller. When a user desires to brush their teeth in a swiveling manner, the exposed first protrusion 452a can be pressed. The exposed first protrusion 452a is supported by the second elastic rotation restoration portion 454. The part is covered.

[0357] According to yet another example, instead of the first protrusion 452a and the second protrusion 452b, The rod is, for example, a long rod with a circular cross section.

One end of the toothbrush head portion 410 and one end of the handle portion 420 are provided with the toothbrush head. A hole is provided between the tooth portion 410 and the handle portion 420. The brush head 410 is rotatable relative to one end of the brush head 410 and is rotatable relative to one end of the handle 420. Here, the rod, the toothbrush head portion 410, and A second elastic rotation restoration portion 454 is disposed so as to surround at least a part of the handle portion 420. That is, the second elastic rotation restoring portion 454 causes the rod and the toothbrush to rotate. The head portion 410 and the handle portion 420 are connected together.

[0358] 55 to 60 are diagrams for explaining other embodiments of the present invention. Only the above will be explained, and explanations of overlapping parts will be omitted. 56 shows a plan view, FIG. 57 shows a side view, and FIG. 58 shows the first embodiment. 59 shows one protrusion 412 and FIG. 59 shows a second protrusion 422.

[0359] As shown in Figures 55 to 60, an elastic toothbrush according to one embodiment of the present invention The brush head portion 410, the handle portion 420, the first elastic rotation restoring portion 452, the second elastic rotation restoring portion 453, and the like are provided. The second elastic rotation restoration portion 454 may be omitted. good.

[0360] In the embodiment described in FIGS. 55 to 60, the technical concept of the present invention is applied to a general toothbrush. It goes without saying that the invention can be applied to molar toothbrushes.

[0361] The toothbrush head portion 410 and the handle portion 420 are separate and independent structures. The toothbrush head 410 has a first protrusion 412 at one end thereof. A second protrusion 422 is provided at one end of the first protrusion 412. The second protrusion 422 extends in the direction of the handle 420. 10. It extends and protrudes in the direction of 10.

[0362] Here, an empty space is provided inside the first protrusion 412. The first protrusion 412 has a hollow circular cylinder shape. Therefore, the second protrusion 422 has a hollow The toothbrush head 410 and the handle 42 have a circular cylindrical shape. When the 0 is joined, a rotating accommodation hollow (E) is provided inside.

[0363] As shown in FIGS. 56 and 57, one end of the first protrusion 412 is connected to the toothbrush circumferential wall. The more it goes from the transfer receiving hollow (E) to the radially outer side, the more it inclines downward in the direction of the handle portion 420. The toothbrush head portion is horizontal in the Y-axis direction, and the toothbrush head portion is The second protrusion 422 is inclined upward in the direction of 410. Can be molded.

[0364] The toothbrush head 410 has a first elastic rotation restoring portion in the direction of the handle 420. For example, the first elastic rotation restoration part 452 is provided in the rotation accommodation hollow (E). The first elastic rotation restoration portion 452 is somewhat narrow and extends at least partially through the first elastic rotation restoration portion 452. 55, has a thick plate-like structure. The first elastic rotation restoration portion 452 is relatively narrow in the width direction (Y direction), and is shown in the side view of FIG. As shown in FIG. 57, the first elastic rotation restoration portion 452 has a relatively small thickness in the height direction (Z direction). As a result, the first elastic rotation restoration part 452 is able to withstand twisting deformation during tooth brushing using the rolling method. The shape of the first elastic rotation restoration portion 452 is an example. As mentioned above, the width and height directions can be reversed, and the cross section can be + shaped. The cross section can have fewer or more wings than the + shape, and two plates are arranged side by side. It can also be placed.

[0365] The thickness of the first elastic rotation recovery portion 452 is set to allow torsional deformation of the longitudinal axis. For example, the thickness of the first elastic rotation restoration portion 452 is 0.1 mm to 1.2 mm. More specifically, the wings are available in sizes of 0.2mm, 0.3mm, 0.4mm, 0.5mm, and 0. 6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, or 1.2mm This is an example, and is a thickness that allows twisting deformation around the longitudinal axis of the toothbrush. If so, it is possible.

[0366] In the following, the shape of the first elastic rotation restoration portion 452 is the shape shown in FIGS. 56 and 57. Let us consider the case.

[0367] The first elastic rotation recovery portion 452 is capable of torsional deformation around the longitudinal axis of the toothbrush and its In order to release restoring energy, the toothbrush head portion 410 and the handle portion 420 are connected to each other. In this case, one end of the first elastic rotation restoring portion 452 is provided on one side of the handle portion 420. The container is accommodated in the accommodation opening C (see FIG. 59).

[0368] After the toothbrush head 410 and the handle 420 are combined, the first protrusion 4 12 and at least a part of the second protrusion 422 are attached by a second elastic rotation restoration portion 454. The second elastic rotation restoring portion 454 is surrounded by the toothbrush head portion 410 and the handle portion 4 It acts as a binder to bind 20.

[0369] The toothbrush head portion 410, the first protrusion portion 412, the first elastic rotation restoration portion 452, the front The grip portion 420 and the second protrusion portion 422 are made of a hard material, and the second elastic rotation restoration portion 45 4 is made of soft material. The hard material is, for example, plastic, eco-friendly material, biodegradable plastic. The soft material is made of at least one of thermoplastic resin, rubber, and The material is at least one of a silicone-based material, a polymer-based material, and a silicon-based material.

[0370] Due to the above-mentioned bonding relationship and material relationship, when brushing teeth using the rolling method, the first elastic rotation The restoring portion 452 is torsionally deformed in the rotation accommodation hollow (E), and the second elastic The rotation restoration portion 454 also undergoes deformation that extends in the circumferential direction around the X axis. The first elastic rotation restoration portion 452 and the second elastic rotation restoration portion 454 are rotated in the S direction in FIG. In other words, it is possible to provide an elastic restoring force in either direction on both ends.

[0371] Unlike the above-mentioned example, the second elastic rotation restoration part 454 is It may also be at least partially satisfied.

[0372] In the above example, the toothbrush head 410, the first protrusion 412, the first elastic The rotation restoration portion 452 is formed as a single part, and the handle portion 420 and the second protrusion portion 422 are different. The parts are injected separately.

[0373] For example, the toothbrush head part 410, the first protrusion part 412, the first elastic rotation restoring part 4 52, the handle portion 420 and the second protrusion portion 422 can also be injected as a single part. In this case, the receiving opening (C) can be omitted. A first protrusion 412 and a second protrusion 422 movable relative to the first protrusion 412 As a result, the second elastic rotation recovery portion 454 retains the torsional elastic energy. It can be stored and released.

[0374] In the above example, the first protrusion 452 and the second protrusion 454 are provided. However, one of the two can be omitted. In this case, the remaining protrusion can be omitted. The second elastic rotation return portion 454 may extend further in the direction of the abbreviated protrusion. can be.

[0375] In the above-described example, the first elastic rotation restoring portion 452 is 10 toward the handle portion 420. The first elastic rotation restoration portion 452 is inserted into the toothbrush head portion 410 from the inside of the handle portion 420. In this case, the toothbrush head 410 may have a receiving opening formed on the inside thereof. will be established.

[0376] Furthermore, in the above-mentioned example, the first elastic rotation restoration part 452 and the second elastic rotation restoration part Although it is assumed that the base portion 454 provides an elastic rotational restoring force, one of the two portions may be omitted. be.

[0377] For example, the first elastic rotation restoration portion 452 can be omitted. The elastic rotation restoring portion 454 provides an elastic rotation restoring force. The toothbrush still forms a hollow, which is omitted and filled with the toothbrush head or handle.

[0378] For example, the second elastic rotation restoration portion 454 can be omitted. In this case, the first elastic The rotational restoring portion 454 provides an elastic rotational restoring force.

[0379] According to one example, an opening (not shown) is provided on one side of the handle portion 420. The opening is located at the lower end (toothbrush holder) of the holding opening (C) (see FIG. 59) provided on one side of the handle portion 420. The first elastic rotation restoration portion 452 is provided at the lower end of the head portion. It passes through the container opening (C) and is exposed through the opening of the handle portion 420.

[0380] This allows the user to press the exposed first elastic rotation restoration portion 452. Depending on whether the toothbrush head part 410 is rotatable or not, the user can When the user desires to brush their teeth in the ring-like manner, the user does not need to press the exposed first elastic rotation restoring portion 452. On the other hand, when the user desires to brush their teeth using the rolling method, the exposed first elastic rotation restoring portion 452 The exposed first elastic rotation restoration part 452 can be pressed against the second elastic rotation restoration part 452. The portion 454 is at least partially covered.

[0381] Furthermore, for the convenience of pushing, the first elastic rotation restoring part 452 is It is wider in the Y direction from the exposed opening than from the sky (E).

[0382] FIG. 60 shows a modified example of the configuration described in FIGS. 55 to 59. do.

[0383] The handle portion 420 is provided with a protruding opening 424. The first elastic rotation restoration portion 452 is inserted into the protrusion opening 424 so as to be relatively rotatable. The torsional restoring portion 454 stores and releases torsional energy about the longitudinal axis of the toothbrush. Here, the first elastic rotation restoration part 452 is inserted into the protrusion opening 424. By doing so, it is possible to reinforce the strength against external forces. 2 can simply function as a rotating part.

[0384] For this reason, the first elastic rotation restoration portion 452 has a long rod shape with a circular cross section. The protrusion opening 424 is configured such that the first elastic rotation restoring portion 452 can rotate relatively inside the protrusion opening 424. It has a shape that can be used.

[0385] Unlike the arrangement of the above-mentioned example, the first elastic rotation restoring portion 452 is configured to function as the first elastic rotation restoring portion 452. However, the protrusion opening 4 is provided on the handle 420, not on the toothbrush head 410. 24 is provided on the toothbrush head portion 410.

[0386] Other explanations, such as the materials of other components, are the same as those explained in FIGS. 55 to 59. It seems that

[0387] FIG. 61 is a diagram for explaining yet another embodiment of the present invention. Only the first part will be described, and the description of overlapping parts will be omitted.

[0388] As shown in FIG. 61, an elastic toothbrush according to an embodiment of the present invention has a toothbrush head. The handle portion 420 includes a first elastic rotation restoration portion 452 therebetween. In the embodiment described below, it is assumed that the technical concept of the present invention is applied to a molar toothbrush. However, it goes without saying that the present invention can be applied to ordinary toothbrushes.

[0389] As shown in FIG. 61, the first elastic rotation recovery portion 452 has a helical screw shape. This allows for the storage and release of torsional energy that deforms around the longitudinal axis of the toothbrush. In another aspect, the thin plate-like elastic member described in FIG. It can be understood that the first elastic rotation restoration part has a spiral structure. The transposition portion 452 may have a double helix structure, like a base structure.

[0390] The thickness of the first elastic rotation recovery portion 452 is set to allow torsional deformation of the longitudinal axis. For example, the thickness of the first elastic rotation restoration portion 452 is 0.1 mm to 1.2 mm. More specifically, the wings are available in sizes of 0.2mm, 0.3mm, 0.4mm, 0.5mm, and 0. 6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, 1.1mm, or 1.2mm This is an example, and is a thickness that allows twisting deformation around the longitudinal axis of the toothbrush. If so, it is possible.

[0391] The thickness of the first elastic rotation restoration part 452 varies depending on the direction. The thickness increases from the handle portion 410 toward the handle portion 420.

[0392] The spiral structure of the first elastic rotation restoring portion 452 extends from the toothbrush head portion 410 to the handle portion 412. 420 direction, and may have a phase change of one period, or may have a phase change of less or more than this. It is possible.

[0393] The spiral structure of the first elastic rotation restoring portion 452 extends from the toothbrush head portion 410 to the handle portion 412. In the direction of 420, the pitch distance becomes shorter or longer. If the pitch distance becomes longer, When thickened, the elastic twisting force is more strongly provided near the toothbrush head portion 410. .

[0394] As described above, the surface of the first elastic rotation restoration part 452 has a second elastic rotation restoration part 453. The second elastic rotation restoring portion has one end and the other end connected to one end of the toothbrush head portion 410. At least a part of the end of the handle portion 420 and at least a part of one end of the handle portion 420 Of course, the second elastic rotation restoration portion 454 may be omitted. .

[0395] According to an example, the first elastic rotation restoration part 452 has the first elastic rotation restoration part 45 At least one hole is provided along the longitudinal direction of the 2. For example, three holes are provided. The second elastic rotation restoration portion is provided in this hole. The first elastic rotation recovery portion 452 is made of a harder material than the second elastic rotation recovery portion. That is, when the first elastic rotation recovery portion 452 is made of plastic, When the second elastic rotation recovery part is made of rubber, the first elastic rotation recovery part 452 When the toothbrush is twisted by the toothbrushing method, the first elastic rotation restoring portion 452 The hole shape may be deformed. When the second elastic rotation restoring portion is provided, the second elastic rotation restoring portion is The elastic rotation recovery portion is also deformed. That is, the second elastic rotation recovery portion is compressed and deformed, and the The elastic rotation recovery part 2 can also provide recovery force while recovering the deformed shape. For this purpose, the second elastic rotation restoration part is formed by the hose of the first elastic rotation restoration part 452. It is arranged in a dot shape to fill only the hole, and covers other parts in addition to the hole. It can also be arranged as follows.

[0396] On the other hand, as shown in FIG. 48, the second elastic rotation restoring portion has an uneven surface, for example, , has a mesh structure.

[0397] In the modification shown in FIG. 61, the first elastic rotation restoring portion 452 is The head portion 410 and the handle portion 420 are integrally formed with at least one of them. The first elastic rotation restoring portion 452, the toothbrush head portion 410, and the handle portion 420 are , is manufactured by a single injection process. In another aspect, the first elastic rotation restoration portion 452 is The toothbrush head portion 410 and the handle portion 420 are made of the same material, for example, plastic. That is, even if the first elastic rotation restoration portion 452 is made of plastic, As shown in the figure, the cross section has a thin plate shape, so it can be twisted and restored. According to one example, the first elastic rotation restoring portion 452, the toothbrush head portion 410, The handle 420 is made of at least one of eco-plastic, biodegradable material, and metal. It consists of the following substances.

[0398] The second elastic rotation and recovery part is the first elastic rotation and recovery part 452, the toothbrush head The handle portion 410 is made of a material that is more deformable than the handle portion 420 in response to an external force, i.e., flexible. They are made of a variety of materials, such as thermoplastic resins, rubbers, silicones, and polymers. That is, the second elastic rotation recovery portion is manufactured by the above-mentioned double injection or insert process. You can take advantage of the process.

[0399] This technical concept can be applied to any toothbrush, including molar toothbrushes and general toothbrushes, without any restrictions. can be done.

[0400] The present technical matter also relates to a method in which the toothbrush head part 410 is attached to and detached from the handle part 420. This is similar to what was explained in FIG. 44. As described above in 44, an end handle portion 422 is further provided. The handle portion 420 can be made of the same material as the handle portion 420. The handle 422 and the handle 420 are connected by a connecting part. The handle portion 422 and the handle portion 420 are manufactured using the same material and in the same injection process. In the injection process, the end handle portion 422 and the handle portion 420 can be taken as a single body. This facilitates the subsequent double injection process of the second elastic rotation restoring portion. In the injection process, the end handle portion 422 and the handle portion 420 are manufactured from two bodies. In this case, the difficulty of double injection design and stage can be eliminated. Here, the first elastic rotation The path of the end handle portion 422 through which the recovery portion 452 passes is wider than that of the second elastic rotation recovery portion. As illustrated in FIG. 44, the first elastic rotation restoring portion is disposed on the toothbrush head portion. However, it may be arranged on the handle side instead. It was assumed that the restoration part would be placed in the toothbrush head, but this was not the case. It may also be placed on the head side.

[0401] The embodiments herein can be combined with each other in various ways. The toothbrush head part in one drawing and the handle part in another drawing, and the elastic rotation recovery part in still another drawing The parts can be combined in various ways.

[0402] As described above, the elastic rotation restoration portion 450 (also applicable to the first and second elastic rotation restoration portions) The surface of the (usable) is roughened to facilitate the storage and release of elastic energy. For example, a mesh structure in the diagonal direction (the diagonal mesh direction of "230" in Figure 10) The mesh is formed not in the mesh direction but in the longitudinal and / or transverse directions, or in a combination of these. It goes without saying that it is possible to combine them. In the case of a functional toothbrush, the toothbrush head and handle must rotate smoothly when they are at a predetermined angle. It can have a predetermined shape so that

[0403] The embodiment described above with reference to FIGS. 1 to 61 is directed to a toothbrush. The idea is an elastic recovery mechanism that is also applied to other products. It is not only for the purpose of rollover restoring force but also for other applications. For example, animal toothbrushes, molar toothbrushes, tongue cleaners, ear picks, industrial articulated razors, It can be applied to other structures for human body, industrial and domestic use (without any restrictions on the scope of application). For example, when applied to a tongue cleaner, the tongue cleaner should be designed to conform to the curved surface of the tongue. Since the position of the part can be changed, it is possible to perform cleaning in close contact. When applied to an earpick, deformation of the elastically deformable part may cause unintended force to be applied to the ear. This prevents the ear from being caught and adds elastic force to the ear picking force, improving the efficiency of the ear pick. When applied to a razor, it is provided between the razor blade and the handle to prevent the razor blade from The elastic deformation and recovery portion is deformed so that the elastic deformation and recovery portion comes into good contact with the skin. The concept is not limited to the toothbrush shown as an example, but can be applied to a variety of fields. .

[0404] For example, the bending strength of the bristles varies depending on the position of the toothbrush bristles. For example, when the brush bristles are placed on the tooth surface during the preparation for the rolling technique, small external When external force is applied through the handle, the bristles can bend to some extent. The more the bending degree increases, the more force (operation of the handle) is required to bend further. For this purpose, the elastic rotation restoration unit (the first elastic rotation restoration unit) according to the present embodiment is Bending strength of at least one of the first elastic rotation recovery portion and the second elastic rotation recovery portion is determined taking into consideration the shape of the toothbrush bristles (meaning the shape of the toothbrush bristles that are bent when brushing your teeth). For example, the toothbrush bristles are in a spread state where no external force is applied (i.e., before starting to brush your teeth). The elastic rotation recovery part (the elastic rotation recovery part, the first elastic rotation recovery part) is most easily bent by the , and the second elastic rotation restoring portion) is a portion that is stronger than the external force of the toothbrush. When applied, the flexural strength may be such that it begins to twist.

[0405] The elastic rotation restoration unit according to this embodiment (the elastic rotation restoration unit, the first elastic rotation restoration unit, and the second elastic rotation restoration unit) The elastic rotation restoring portion (meaning at least one of the elastic rotation restoring portions) is at least partially moved out of the mouth during tooth brushing. It can be located at.

[0406] For example, the toothbrush head and handle are made of plastic, eco-friendly materials, and biodegradable plastic. It is made of plastic or silicone.

[0407] By way of example, the toothbrush bristle shapes described in FIG. 3 may be applied to other embodiments. .

[0408] Although the present invention has been described in detail above using preferred embodiments, the scope of the present invention does not necessarily extend beyond the scope of the specific embodiments. The present invention is not limited to the embodiments, but should be interpreted in terms of the appended claims. A person skilled in the art would be able to You will understand that many modifications and variations are possible.
