Description

Toothbrush with variable toothbrush bending at right angles {TOOTHBRUSH WITH A BENDABLE NECK}

The present invention relates to a toothbrush in which the toothbrush is bent at right angles.

Brush your teeth before or after meals in your daily routine. For brushing methods recommended by dental institutions, it is recommended to brush the upper teeth (UT) downward and the lower teeth (DT) upward with the toothbrush at right angles to its surface or inner surface as shown in FIG. .

Since teeth are curved in a semi-circular arc rather than in a straight line, the toothbrushes have been proposed in various ways regarding the toothbrush or the shape of the toothbrush neck.

However, the basic form of the conventional toothbrush is a toothbrush and handle bar is a straight form because the problem of the vertical movement of the toothbrush according to the lever operation of the arm and wrist of the human body was not considered much.

However, as shown in Fig. 4, in order to wipe the teeth up and down using a so-called straight toothbrush, the wrist (h) holding the toothbrush is almost horizontal and spins only the wrist left and right in place. The movement allowed the toothbrush to move up and down locally within the oral cavity. At this time, in the case of the right-handed, it is unnatural for the left tooth of the oral cavity, but the inconvenience of the brushing operation of the upper and lower sides can be partially overcome by repeated practice. However, on the right side of the mouth, the wrist holding the toothbrush and the toothbrush overlap in the same direction, so the wrist must be severely bent. In this state, the wrist is difficult to spin, so it is very difficult to brush the toothbrush up and down against the tooth. Increasingly, most of the time, brushing in a diagonal direction, or brushing horizontally and comfortably in most cases.

Therefore, it is difficult to remove food debris due to non-contact between the interdental tooth and the toothbrush, and the prog of the tooth progresses and eventually causes tooth decay.

It is an object of the present invention to correct this conventional problem and to provide an ergonomic toothbrush which is a toothbrush neck that can be brushed up and down in the condition that the operation of the arm and wrist of the human body is easily changed at right and left angles in the handle bar.

Still another object of the present invention is to provide a mechanical means capable of maintaining the bent state even if the toothbrush neck is bent to either side of the toothbrush.

The present invention is in the configuration of the ergonomic toothbrush that can move the toothbrush up and down in the conditions of easy operation of the arm and wrist of the human body. In other words, the toothbrush is installed on the handle bar to be configured to be bent in a right angle.

As indicated in FIG. 5. Arm (a) is connected to the shoulder of the body can be jointed in the shoulder, elbow, hand (h) neck. To move the toothbrush up and down locally to the oral cavity, moving the wrist up and down is physically easier and more comfortable than moving the wrist up and down. This is because the wrist and wrist joint motion is synthesized because of less force and no spin movement of the wrist, the wrist is comfortable and the vertical movement is natural. Therefore, if the wrist holding the toothbrush moves up and down to wipe the teeth up and down, it is inevitable that the toothbrush is preferably bent at right and left angles with respect to the handle bar. Of course, the shape of the neck of the toothbrush is not considered here.

From an ergonomic point of view, moving the toothbrush handle up and down is much easier than spinning in a horizontal position, so it is best to brush your teeth up and down when the toothbrush is bent at right angles to the handlebar. Able to know.

In the present invention, since the toothbrush is bent in the neck, the toothbrush flows into the oral cavity, so the handle is not impeded, and thus the surface and the inner surface of the tooth can be easily cleaned regardless of the left or right side of the oral cavity.

There is a conventional T-type toothbrush, which is because the neck is formed vertically in the middle of the toothbrush, when the toothbrush tries to put deeply into the left and right of the mouth, the neck of the toothbrush is caught and the brushing of the inner molar is uncomfortable, but the present invention is inconvenient. This problem is solved.

The present invention has developed a toothbrush that is variable in the ergonomic aspect of the toothbrush neck bent at the right and left angles in the handle bar as described above. For example, a toothbrush having a function of actually brushing teeth, a neck of a toothbrush that allows the toothbrush to be deeply introduced into the mouth while being connected to a handlebar, and a neck of the toothbrush are connected to the toothbrush in an arbitrary direction The basic configuration of the moving handle bar. This basic configuration makes no difference to other toothbrushes.

In the present invention, the neck and the handle rest is composed of a separate body, because the functionality to be bent at right and right angles to the handle stand of the toothbrush, and the neck portion of the toothbrush as a means for varying and fixing a predetermined angle The rotating plate is formed integrally with the groove is formed in a right angle direction, the rotating plate is rotated left and right in the installation groove formed in the front end of the toothbrush stand to be bent at right angles.

In addition, inside the handle bar, a stopper coupled to the paper groove of the pivot plate is installed with a spring and a flop so as to be operated by a knob, and the neck of the toothbrush artificially bent at right and left angles at the joint of the handle bar is rotated. It is fixed and held by a stopper coupled to the papermaking groove of the copper plate.

Therefore, the neck of the toothbrush is not shaken or altered by the frictional resistance while using the toothbrush, thereby maintaining the bent state of the toothbrush firmly and safely.

In addition, holding the handle of the toothbrush can be easily brushed up and down because the toothbrush is easy to move up and down.

The present invention means for bending the neck of the toothbrush at right angles to the handle restraint is not limited to that shown in the drawings described below, it is possible to employ a ball or lever instead of a stopper to the rotating plate formed in the neck of the toothbrush. In addition, by adopting a sprocket, gear mechanism, articulation mechanism instead of the rotating plate, the toothbrush can be maintained at a right angle, and the toothbrush angle can be bent by arbitrarily adjusting the displacement angle of the target toothbrush according to the habit.

Toothbrush bent at a right angle according to the present invention is easy to wipe up and down with respect to the teeth while holding the handle bar and the toothbrush easily contact between the interdental can be cleaned more effectively to effectively maintain the health of the teeth There is.

According to the accompanying drawings, the most preferred embodiment in the means for bending the toothbrush neck according to the present invention in a right and left right angle at the adhesion portion of the handle stand as follows.

1 and 2 is a block diagram of a toothbrush of the present invention. In the toothbrush 1, a toothbrush head 2a is formed of a toothbrush head 2 for planting and substantially brushing the teeth 2a and a neck part 3 for connecting the toothbrush head to the handle 5, where the neck of the toothbrush ( 3) and the handle bar (5) is composed of a separate body and the rotary plate (4) formed with a plurality of paper grooves (4a) (4b) (4c) around the center in the right angled direction at the lower end of the neck (3) integrally Formed. An installation groove 5b of the rotation plate 4 is formed at the left and right in the range of 180 degrees around the tip contact portion 5a of the handle 5 so that the rotation plate 4 is formed in the installation groove 5b. The neck 3 of the toothbrush 1 is inserted into and adhered to the support shaft 4p that penetrates the shaft hole 4h of the pivoting plate 4 and the shaft hole 5h of the tip coalescing portion 5a of the toothbrush stand 5a. Is variable at right and left angles. In the inner hollow chamber 5c of the handle stand 5 of the toothbrush, a stopper 6 coupled to the papermaking groove of the pivot plate 4 to stop the spring 6s and the spring 6s is installed to support the spring. The knob 6n, which is screwed into the lower end threaded portion 5d of the hollow chamber 5c and screwed into the lower end threaded portion 5d of the hollow chamber 5c, is operated as a guide groove 5e of the handle 5 by a knob 6n. The rotating plate 4 can be released by protruding to the outside and pulling the stopper 6. When the abdomen 3 of the toothbrush 1 is bent at a vertical or right angle, the stopper 6 is pushed upward by the elastic force of the spring 6s so that the upper end 6t of the stopper 6 is rotated on the rotating plate 4. Is coupled to any one of the paper grooves of the paper groove (4a) (4b) (4c) is configured to be fixed to the toothbrush neck (3) in a straight line or right and left.

Referring to the operation of the present invention configured as described above are as follows.

Basically, when the neck part 3 of the toothbrush 1 and the handle bar 5 form a straight rod 상단, as shown in FIG. 1, the upper end part 6t of the stopper 6 is formed on the rotating plate 4. The neck 3 of the toothbrush 1 is engaged with the handle 5 in a straight line by being coupled to the lower papermaking groove 4b.

In addition, when bending the neck 3 of the toothbrush 1 to clean it, as shown by the dotted line in Fig. 1, the knob 6n is first operated downward to stop the stopper 6 from the papermaking groove of the rotating plate 4. After exiting from (4b) and letting it free, the neck 3 of the toothbrush 1 is bent at right angles in any direction. When the neck 3 is bent to the left, the upper end 6t of the stopper 6 is engaged and fixed to the papermaking groove 4a of the pivoting plate 4, and the neck 3 of the toothbrush 1 is bent to the right. In one case, the upper end portion 6t of the stopper 6 is coupled to the papermaking groove 4c of the rotating plate 4 to be bent and maintained. Since the spring 6s always has a repulsive force against the stopper 6, simply pull and release the knob 6n to return the stopper 6 to the papermaking grooves 4a, 4b and 4c of the rotating plate 4. Will be combined with either).

As shown in Fig. 5, the toothbrush 1 is bent upright to hold the handle bar 5 bent, and the toothbrush 1 of the neck 3 bent at right angles is brushed in the vertical direction so as to come into contact with the teeth and cleanly brush it. When brushing teeth, the bent toothbrush (1) does not open or flow, so it is like brushing teeth with a right-angled toothbrush.

After use, the toothbrush may be left in a bent state, or the toothbrush may be extended in a straight line with the handle bar in the reverse order of bending.

In the present invention, since the toothbrush is configured to be bent at right and left angles with respect to the handle bar, the toothbrush maintains the horizontal direction even when the handle bar is held upright, so that the hand holding the toothbrush bar is operated up and down to the toothbrush up and down with respect to the teeth of the oral cavity. It's easy to clean, and the ergonomic hands and arms move up and down, so brushing is very comfortable.

In addition, the toothbrush neck can be bent at right and left angles by releasing the pivoting plate by operating the knob, so that the right and left molar teeth of the oral cavity can be easily wiped, and the toothbrush can be bent in an arbitrary direction to clean the inner surface of the tooth. Also, when brushing, the handle does not interfere with the mouth.

In addition, when the toothbrush is packaged, the toothbrush and the handle rest in a straight line to be stored in a small volume and can be packaged like a conventional toothbrush.

In addition, the present invention solves the problems of the conventional toothbrush and can be wiped cleanly with a more comfortable operation can have a variety of effects, such as to keep the teeth healthy.
