An arc-shaped insertion hole is formed so that the surfaces of the first brush plate and the second brush plate that do not have a brush body are brought into contact with each other, and each of the first brush plate and the second brush plate is brought into contact with each other. A pivot is inserted into a central hole provided in the center, and the first brush plate and the second brush plate are pivotally pivoted by the pivot, and the first lid body and the second lid disk. The present invention relates to a fingertip washer characterized in that finger holes into which fingertips can be inserted are formed in the respective shaped portions.

  Conventionally, there have been various instruments that can be cleaned by inserting a fingertip. Such fingertip cleaners clean the fingertips quickly when the fingertips are contaminated with machine oil, etc., mainly in field work such as in factories, and even remove stubborn dirt that has entered between the fingertips and nails. It is made so that it can be used, and a large number of rigid hair bundles are planted on a synthetic resin base, and the hair tips of the hair bundles are applied to the fingertips to clean the fingertips. Is.

  The “fingertip cleaner” described in the following Patent Document 1 is a combination of a cylindrical “band-shaped brush” in which hair bundles are implanted on the inner wall and a substantially disk-shaped “pedestal brush” in which hair bundles are also implanted on the upper surface. It can be cleaned by putting a fingertip into the space where the hair bundle protrudes, and is handled by gripping the whole with the other hand. That is, the bundle with the hair bundles planted outward is folded inward, and the use state is very similar to the bundle.

  Next, the “fingertip cleaner” described in Patent Document 2 below is similar in structure to the “fingertip cleaner” described in Patent Document 1, but a drive device can be added to the bottom plate. When the fingertip is inserted into the “fingertip cleaner”, cleaning is performed without moving the fingertip by the action of a driving device that performs reciprocal rotation.

Next, the “fingertip washer” described in Patent Document 3 below is a structure in which a high-speed rotating brush that is rotated at high speed by a planetary gear is added to the configuration of the “fingertip cleaner” described in Patent Document 2. In addition to cleaning the four fingernails, it is possible to clean the thumb nails and remove dirt on the surface and sides of the nails.

The body part is fixed, and an arc-shaped insertion hole through which each of the two or more connecting shafts of the first brush disk is inserted is formed in the second brush disk. The first brush disc has an arc-shaped insertion hole through which each of the two or more connecting shafts of the second brush disc is inserted, and does not have the brush bodies of the first brush disc and the second brush disc. The surfaces are brought into contact with each other, and a pivot is inserted into a center hole provided at the center of each of the first brush disc and the second brush disc, and the first brush disc and the second brush disc are rotatable by the pivot. The fingertip washer is characterized in that finger holes into which the fingertips can be inserted are formed in the disc-shaped portions of the first lid body portion and the second lid body portion.

  In the fingertip cleaner according to the solution of the present invention, each fingertip of one hand is inserted into a finger hole drilled in the first lid body, and the other is inserted into the finger hole drilled in the second lid body portion. Each fingertip of the hand is inserted to relatively rotate the first lid body portion and the second lid body portion, and at the stop point, the first lid body portion and the second lid body portion are relatively moved in the opposite directions. By rotating, each fingertip inserted into the first lid body is washed by rotation of the brush body of the second brush body, and each fingertip inserted into the second lid body portion is cleaned by the first brush body. Washed by rotation of brush body. That is, it is possible to wash the fingertips of both hands simultaneously.

Furthermore, since the fingertip cleaner described in the solution of the present invention does not use a driving device, it does not require a power source and can be formed extremely compactly. Further, the first brush disc is rotated by the rotational force applied to the first lid portion with one hand, and the second brush disc is rotated by the rotational force applied to the second lid portion with the other hand. As a result, the fingertips of both hands are cleaned at the same time by the first and second brush plates that rotate relatively, so that the cleaning method is simple and effective.
Furthermore, the change of the rotation speed and the start / stop can be freely controlled depending on the force applied to the fingertip by the user.

The fingertip cleaner F of the first embodiment may use the front side for the left hand and the back side for the right hand, or vice versa. Here, the front side is used for the left hand and the back side is used for the right hand. The case will be described.

A user (not shown) grasps the front side of the fingertip cleaner F of Example 1 with the left hand and the back side with the right hand, and first inserts the thumb of the left hand into the finger hole 13 of the first lid 1. The index finger is inserted into the finger hole 17, the middle finger is inserted into the finger hole 16, the ring finger is inserted into the finger hole 15, and the little finger is inserted into the finger hole 14. Next, the right thumb is inserted into the finger hole 23 of the second lid 2, the index finger is inserted into the finger hole 24, the middle finger is inserted into the finger hole 25, the ring finger is inserted into the finger hole 26, and the little finger is inserted into the finger hole 27, respectively. To do. Note that the user is free to insert each finger of the left hand first, each finger of the right hand first, or each finger of both the left and right hands at the same time.

Each finger of the left hand inserted into the finger holes 13 to 17 of the first lid 1 is inserted to a certain depth in a plurality of hair bundles b, b,... Constituting the brush body B2 of the second brush disc 4. Each finger of the right hand inserted into the finger holes 23 to 27 of the second lid 1 has a certain depth in the plurality of hair bundles b, b,... Constituting the brush body B1 of the first brush disc 3. Is inserted. At this time, due to the action of the flanges 13a to 17a of the finger holes 13 to 17 and the flanges 23a to 27a of the finger holes 23 to 27, each finger comes into contact with the edges of the finger holes 13 to 17 and the finger holes 23 to 27. But each finger doesn't feel pain. If the flanges 13a to 17a and 23a to 27a are missing, the fingers may feel pain when pressed against the edges of the finger holes 13 to 17 and the finger holes 23 to 27, and the fingers are pressed more strongly. Although there is a possibility of being damaged, such a risk is prevented by the action of the flanges 13a to 17a and 23a to 27a. In addition, the prevention effect of a pain and damage is further increased by rounding the junction part of the board | substrate 11 and the flanges 13a-17a and the junction part of the board | substrate 21 and the flanges 23a-27a.

The user inserts each finger of the left hand into the finger holes 13 to 17 of the first lid part 1 and each finger of the right hand to the finger holes 23 to 27 of the second lid part 2 and Rotate the right hand relatively. That is, when the left hand is rotated counterclockwise in front view of the fingertip cleaner F, the right hand is rotated relatively clockwise, and the left hand is rotated clockwise in front view of the fingertip cleaner F. When rotated to the right, the right hand tip rotates relatively counterclockwise. In addition, when the right hand is rotated counterclockwise in the front view of the fingertip cleaner F, the left hand is rotated relatively clockwise, and the right hand is rotated clockwise in the front view of the fingertip cleaner F. When it is rotated to the left, the left hand tip rotates relatively counterclockwise.

Now, in order to simplify the description, the case where the right hand is rotated counterclockwise in front view of the fingertip washer F with the left hand held stationary will be described with reference to the schematic diagrams of FIGS. It is shown. 13a to 13d, the connecting shaft 6 is positioned at the left end of the insertion hole 46 of the second brush disc 4, the connecting shaft 7 is positioned at the right end of the insertion hole 47 of the second brush disc 4, and the connecting shaft 8 is the first shaft. A state where the connecting shaft 9 is positioned at the upper end of the insertion hole 39 of the first brush disc 3 is shown at the lower end of the insertion hole 38 of the brush disc 3. In this state, FIG. 13a shows the state of the first lid part 1, FIG. 13b shows the state of the second brush board 4, FIG. 13c shows the state of the first brush board 3, and FIG. 13d shows the second lid part. Each of the states 2 is schematically shown. In the schematic diagrams of FIGS. 13 to 15, the brush bodies B <b> 1 and B <b> 2 are omitted.

In this state, when the left hand inserted into the first lid part 1 is placed in a stationary state and the right hand inserted into the second lid part 2 is rotated counterclockwise when viewed from the front. The first brush body 3 connected and fixed to the first lid 1 and the first lid 1 by the connecting shafts 6 and 7 is stationary, but the second lid 2 and the second lid. The second brush disk 4 connected and fixed to 2 by connecting shafts 8 and 9 rotates counterclockwise (direction X) in a front view. Therefore, although the connecting shafts 6 and 7 are stationary, the connecting shafts 8 and 9 rotate counterclockwise (direction X) when viewed from the front. 13a to 13d, the connecting shaft 6 is inserted at the left end of the insertion hole 46, the connecting shaft 7 is inserted at the right end of the insertion hole 47, the connecting shaft 8 is inserted at the lower end of the insertion hole 38, and the connecting shaft 9 is inserted. Since they are respectively located at the upper ends of the holes 39, it is impossible to rotate the right hand tip clockwise in front view or the left hand tip counterclockwise in front view in this state.

14a to 14d show a state in which the second lid portion 2 has been rotated 45 ° counterclockwise (direction X) in a front view from the states of FIGS. 13a to 13d. Therefore, the 2nd brush board 4 will also be in the state rotated 45 degrees counterclockwise (direction X) by front view. In this state, the center c6 of the connecting shaft 6 coincides with the center c46 of the insertion hole 46, the center c7 of the connecting shaft 7 coincides with the center c47 of the insertion hole 47, and the center c8 of the connecting shaft 8 is the center of the insertion hole 38. coincides with c38, and the center c9 of the connecting shaft 9 coincides with the center c39 of the insertion hole 39. In this state, FIG. 14a shows the state of the first lid part 1, FIG. 14b shows the state of the second brush disc 4, FIG. 14c shows the state of the first brush disc 3, and FIG. 14d shows the second lid. The state of the body part 2 is shown respectively.

When the second lid 2 is further rotated 45 ° counterclockwise (direction X) from the state shown in FIGS. 14a to 14d, the state shown in FIG. 15 is obtained and the second lid 2 is rotated. The movement is stopped. That is, in the state shown in FIG. 15, the connecting shaft 6 is at the upper end of the insertion hole 46, the connecting shaft 7 is at the lower end of the insertion hole 47, the connecting shaft 8 is at the upper end of the insertion hole 38, and the connecting shaft 9 is at the insertion hole 39. It is obvious that it is impossible to rotate the second lid 2 further counterclockwise (direction X) in front view. In this state, FIG. 15a shows the state of the first lid 1, FIG. 15b shows the state of the second brush disc 4, FIG. 15c shows the state of the first brush disc 3, and FIG. 15d shows the second lid. The state of the body part 2 is shown respectively.

Accordingly, in the next process, the right hand inserted into the second lid 2 is rotated clockwise (Y direction) in front view. That is, the second lid 2, the second brush disc 4, and the connecting shafts 8 and 9 are rotated clockwise (Y direction) in a front view, and the states are as shown in FIGS. 14 a to 14 d. . Further, when the second lid portion 2, the second brush disc 4, and the connecting shafts 8 and 9 are rotated 45 ° clockwise (Y direction) in a front view, the state returns to the state shown in FIGS. 13a to 13d. This completes one cycle.

During this one cycle, the second brush disc 4 rotates 90 ° in the X direction with respect to the first lid 1 and then rotates 90 ° in the Y direction to be in the original state. Accordingly, the left hand tip inserted into the first lid 1, that is, the fingertip (not shown) of each finger is inserted into the brush body B 2 of the second brush disc 4, and the brush body B 2 is X 90 degrees in the direction and then 90 degrees in the Y direction, so that the fingertips (not shown) of each finger are rubbed against the plurality of hair bundles b, b,... Constituting the brush body B2, Washed.

At the same time, the second lid 2 is rotated by 90 ° in the X direction with respect to the first brush disc 3 and then rotated 90 ° in the Y direction so that the original state is obtained. The right hand tip inserted in the inside, that is, the fingertip (not shown) of each finger rotates 90 ° in the X direction with respect to the brush body B1 while being inserted into the brush body B1 of the first brush disc 3, Next, the fingertip (not shown) of each finger is rotated by 90 ° in the Y direction, and is rubbed and cleaned by a plurality of hair bundles b, b,... Constituting the brush body B1.

By repeating the above cycle as appropriate, the fingertip of the left hand and the fingertip of the right hand are washed at the same time. Therefore, the washing operation is repeated according to the degree of dirt, and if it is judged that the dirt has been removed, the washing may be stopped. In the above, the case where the left hand inserted into the first lid part 1 is stationary and the right hand inserted into the second lid part 2 is rotated is shown. Even if the left hand inserted into the first lid 1 is rotated with the right hand stationary, the left hand inserted into the first lid 1 and the right hand inserted into the second lid 2 are simultaneously reversed. Needless to say, even if it is rotated, the fingertips of both hands can be cleaned in exactly the same manner.

FIG. 16 shows another configuration of the brush body. 16a is a rear view of the first brush board 3v having the brush body Bv1 of another configuration, and FIG. 16b represents the configuration of the brush body Bv1 of the first brush board 3v of FIG. 16a as a schematic diagram. 16c is an end view taken along line GG in FIG. 16a, and FIG. 16d is an end view taken along line HH in FIG. 16a.

In FIG. 16a to FIG. 16d, the brush body Bv1 is formed by alternately combining the region L composed of the long brush bundle bl (length D8) and the region S composed of the short brush bundle bs (length D7). Configured. That is, the ring-shaped brush body Bv1 is composed of six sections of substantially fan-shaped areas L, L,... As well as six sections of substantially rectangular areas S, S,.

16e is a front view of the second brush board 4v having the brush body Bv2 of another configuration, and FIG. 16f represents the configuration of the brush body Bv2 of the first brush board 4v of FIG. 16e as a schematic diagram. . 16g is an end view taken along line II of FIG. 16e, and FIG. 16h is an end view taken along line JJ of FIG. 16e.

In FIG. 16e to FIG. 16h, the brush body Bv2 is formed by alternately combining a region L composed of a long brush bundle bl (length D8) and a region S composed of a short brush bundle bs (length D7). Configured. That is, the ring-shaped brush body Bv2 is composed of six sections of substantially fan-shaped areas L, L,..., Just like the brush body Bv1. is doing.

The effects obtained by configuring the brush body Bv1 and the brush body Bv2 as described above are as follows. That is, since the brush body Bv1 and the brush body Bv2 have the region S constituted by the short brush bundle bs (length D7), the fingertip can be easily inserted, and the brush body Bv1 and the brush body Bv2 are rotated. As a result, the fingertip enters the region L constituted by the long brush bundle bl (length D8), and the rotational force of the fingertip is reliably transmitted to the brush body Bv1.

Further, when the fingertip first enters the region L composed of the long brush bundle bl (length D8), it may slide slightly there, but as soon as the brush body Bv1 and brush body Bv2 are rotated. The fingertip is inserted deeply into the region S composed of the short brush bundle bs (length D7), and in this state the fingertip enters the region L composed of the long brush bundle bl (length D8).

In this manner, by providing the brush body Bv1, Bv2 with the region L and the region S where the length of the brush bundle is changed, the fingertip is inserted deeper than when the brush bundle has a uniform length. This means that the fingertip can reliably hold the brush bodies Bv1, Bv2. Furthermore, it means that the reliable turning power of the first brush disc 3v and the second brush disc 4v can be generated. In this regard, the experiment was performed by changing the configuration of the brush body in various ways, but the effect became clear by this experiment.

Next, FIG. 17a is a front view of the first lid portion 1v having a different configuration from the first lid portion 1, and FIG. 17b is a second lid having a different configuration from the second lid portion 2. The front view of the part 2v is shown, respectively. The first lid portion 1v has the same configuration as the first lid portion 1v except that the finger holes 13v are configured to have an area about half that of the finger holes 13 of the first lid portion 1. The second lid portion 2v has the same configuration as the second lid portion 2v except that the finger holes 23v are configured to have an area about half that of the finger holes 23 of the second lid portion 2.

The reason for this configuration is as follows. That is, the finger holes 13, 13v, 23, 23v are all drilled for the purpose of inserting a thumb (not shown), but by making them smaller like the finger holes 13v, 23v. The effect is that the thumb inserted in the finger holes 13v and 23v is less likely to slip. That is, when the finger hole is large, a phenomenon that the inserted thumb slides along the arcuate shape and is not inserted deeply depending on the user, and thus the generation of a reliable turning force is inhibited is also observed. However, the thumb inserted by making the finger holes smaller like the finger holes 13v and 23v immediately collides with the flanges 13va and 23va even if they start to slide, and at this point, the sliding is stopped. Even the user can insert the thumb deeply. As a result, it is possible to guarantee the generation of reliable rotational power.

  As described above, the fingertip cleaner of the present invention does not require a power source and is extremely compact, but can simultaneously clean the fingertips of both hands. In addition, since the rotational movement of one or both hands is configured to clean the fingertips of both hands, it has the same cleaning ability as a fingertip washer having a power supply and a drive device, and it also rotates. Since the user can finely adjust the start and stop of speed and rotation according to his / her preference, it is extremely convenient. Furthermore, since no complicated mechanism is used, there is no failure, maintenance is easy, and the manufacturing unit price is extremely low. Therefore, the fingertip cleaning device of the present invention can be very useful for cleaning fingertips in factories, offices, and general households.
