Description

Toothbrush {toothbrush}

The present invention relates to a toothbrush, and more particularly, to a toothbrush capable of simultaneously brushing both sides of a tooth.

Generally, in the form of a toothbrush, a toothbrush body has a rod shape, a handle is formed on one side of the toothbrush body, and a head portion having bristles embedded on the other side of the toothbrush body is formed so that a user grasps the handle of the toothbrush body, , So as to carry out brushing.

However, since the toothbrush is formed only on one side of the toothbrush body, it is only possible to brush one side (the inner side or the outer side of the tooth) of the tooth, and to brush the outer side of the teeth while brushing the inner side of the tooth, Therefore, it takes much time and a lot of power to the wrist. However, the brushing is not cleaned, and the wrist may be excessively applied to the teeth, resulting in worn teeth.

In addition, since the toothbrush is used to clean the tongue, the roof of the mouth, the gum, and the oral cavity in order to clean the mouth, it is necessary to use the wrist by moving the wrist hardly.

Therefore, it is an object of the present invention to develop a double-sided toothbrush capable of simultaneously brushing both sides of a tooth in a simple and quick manner without applying force to the wrist.

In addition, development of a double-sided toothbrush capable of easily cleaning the inside of the tongue, palate, gums, and mouth without turning the wrist is also required.

On the other hand, Korean Utility Model Publication No. 20-2012-0000595 (Jan. 25, 2012) states that "two toothbrush knobs and two bristles are provided so that two bristles are opposed to each other, And a cam is provided between the two bristle grips to freely adjust an angle of opening of the two bristles. ≪ Desc / Clms Page number 2 >

This technique has the advantage of simultaneously wiping both sides of the teeth, but this has the problem that it is not possible to selectively wipe one side.

Korean Patent Registration No. 10-1002808 (December 14, 2010) discloses a toothbrush comprising a cylindrical toothbrush portion on a cylindrical outer surface for wiping an end portion of a tooth and having a cam and a camshaft protruded at both ends thereof, A front and rear movable toothbrush support frame which is fixed to the toothbrush handle and which is fixed to the camshaft of both sides of the camshaft and is reciprocated up and down by a vertically moving means accommodated in the inner space of the support frame and interlocked with the cam supporting the camshaft, The toothbrush body is separated from the supporting frame and the toothbrush body by the separating and coupling means, and the toothbrush unit of the supporting frame of the forward and backward toothbrush unit is combined with the toothbrush assembly of the supporting frame of the forward and backward toothbrush unit. And a vertically movable toothbrush unit having an opening and closing hole for discharging a debris to expose an inner space when the toothbrush handle is separated from the toothbrush unit. If the toothbrush "is disclosed.

However, this also includes the problems of the prior art.

Korean Patent Registration No. 10-0911412 (Aug. 03, 2009) states that "the rear ends of the first and second toothbrush bodies having bristles on their heads are connected by a connecting ring so that both bristles face each other, And the first and second toothbrush bodies are configured such that the front and rear portions of the first and second toothbrush bodies are formed with curved concave portions capable of slip when facing each other. And the handle of the second toothbrush body is formed with a curved convex portion on the front surface and a curved concave portion on the rear surface so that the curved convex portions of the handle of the first and second toothbrush bodies are accommodated in the curved concave portions of the first and second toothbrush body handle And a frictional portion is formed on the curved convex portions. "

However, in this conventional technique, since the fixed state of the frictional portion between the curved portion and the curved convex portion is not stable, there is a problem that the toothbrush efficiency is lowered because the first stance can not maintain a stable posture when the two-side toothbrush is used.

Korea Utility Model No. 20-2012-0000595 (January 25, 2012) Korea Patent Registration No. 10-1002808 (December 14, 2010) Korea Patent Registration No. 10-0844219 (June 30, 2008) Korea Patent Registration 10-0911412 (August 03, 2009)

First, 'first position' refers to a form of wiping only one side of a tooth, and 'second position' means a form where both sides of a tooth can be simultaneously wiped.

1 is a perspective view showing the configuration of a toothbrush according to the present invention, showing a first positional state. The first toothbrush 100 includes a first toothbrush 100 and a second toothbrush 200 having the same configuration as the first toothbrush 100 and disposed adjacent to the first toothbrush 100. The first toothbrush 100, And second toothbrush (200) in a relatively rotatable manner.

FIG. 2 is a perspective view illustrating the first toothbrush 100 and the second toothbrush 200 separated from each other.

The first toothbrush 100 is integrally formed with the first handle 110 by the first handle 110 and the first elastic connection 130 and the first bristles 122 are formed on the end of the first handle 110, The first supporting portion 120 is integrally formed,

The second toothbrush 200 is integrally formed with the second handle 210 by the second handle 210 and the second elastic connection 230 and the second bristles 222 are formed at the end of the second toothbrush 200 And the second supporting portion 220 is integrally formed.

The coupling means includes a first toothbrush 100 and a second toothbrush 200 that are connected in a variable manner to each other. The bristles of the first toothbrush 100 and the second toothbrush 200 are arranged in parallel, 3) in which the bristles 122 and 222 of the first toothbrush 100 and the bristles 122 of the first toothbrush 200 are arranged to face each other at a predetermined interval ) To be shifted. Preferably, the coupling means is a hinge 310 or 320 that allows the first handle 110 and the second handle 210 to rotate with respect to each other. Preferably, the hinges 310 and 320 are provided on the upper surface of the first handle 110 and the second handle 210, respectively, and are preferably provided at two positions, i.e., the front side and the rear side.

The present invention, on the other hand, includes fixing means for holding the first toothbrush 100 and the second toothbrush 200 in a first position and a second position. The fixing means includes a first position fixing magnet 116 and a second position fixing magnet 216 which are respectively fixed to the surfaces where the first and second knobs 110 and 210 are in contact with each other at the first position, The second position fixing magnets 112 and 212 are respectively fixed to the surfaces where the first and second grip portions 110 and 210 are in contact with each other. At this time, each of the magnets should be installed at a position corresponding to that of the opposite polarity so as to generate attracting force to attract each other to each other. Alternatively, it is also possible to arrange the magnets on either side and to arrange the magnetic bodies at the corresponding positions. The number and shape of the magnets are not limited.

The first and second position fixing magnets 116 and 216 and the second position fixing magnets 112 and 212 are insert molded on the surfaces of the first and second handle portions 110 and 210 , And a protective film (400) is further coated on the surface. The protective film 400 is preferably made of a rubber material having low slippage, and it is also effective to prevent the slippage in hand barbing when brushing, by forming fine protrusions on the surface.

The toothbrush according to the present invention having such a configuration has a first toothbrush 100 and a second toothbrush 200 in a first position, that is, a state in which the first toothbrush 100 and the second toothbrush 200 are arranged side by side, as shown in FIGS. 1 and 3, And the second bristles 222 are oriented in the same direction, only one side of the tooth can be wiped. At this time, the first toothbrush 100 and the second toothbrush 200 maintain mutual movement due to the magnetic force of the first position fixing magnets 116 and 216. At this time, since the area of the bristles is doubled, the tongue can be wiped more quickly and effectively.

4, the second handle 210 of the second toothbrush 200 is rotated 180 degrees with respect to the hinges 310 and 320, as shown in FIG. At this time, a force greater than the coupling force of the first position fixing magnets 116 and 216 must be applied. This operation causes the second toothbrush 200 to move to the upper surface of the first toothbrush 100 such that the second bristles 222 and the first bristles 122 face each other, Position. At this time, the second toothbrush 200 is naturally tightly coupled to each other by the force of the second position fixing magnets 112 and 212 at a position adjacent to the second position so that the toothbrush 200 can be wiped .

In this state, the first bristles 122 and the second bristles 222 are inserted into the both surfaces of the teeth, respectively. At the same time, the bristles generated in the brushing process in the first and second elastic connection parts 130, Absorbs and compensates for deformation applied to the first and second support portions 110 and 220 according to the change in the gap between the bristles 122 and 222 and at the same time provides an appropriate pressing force to the bristles 122 and 222, So that the brushing can be efficiently and stably maintained.

In addition, the protective film 400 covers the magnet for fixing the hinge and the position, so that the feeling of being transferred to the user's hand is minimized and the slip is reduced.

The above description is only an example of the present invention, and the present invention is not limited to this, and the replacement of the equivalents and the simple design change within the scope of the present invention are within the scope of protection of the present invention Should be understood as belonging to.

For example, the coupling means may be of a coupling type different from that of the hinge of the embodiment. That is, both sides of the thin film sheet can be fused to the first handle 110 and the second handle 210 to be rotatable. In this case, the first toothbrush 100 and the second toothbrush 200 may be simultaneously formed with one mold during the injection process.
