Abstract

PURPOSE:To satisfactorily and easily scrub and eliminate fixed contamination without damaging a contact lens by rotating one buff body placed on a case body side, while inserting and pressing the contact lens between said buff body and the other buff body placed on a cover body side, based on rotation driving force of a motor. CONSTITUTION:One buff body placed on a case body 10 side is brought to rotational operation by a motor 22 placed in the case body 10. As a result, a contact lens 34 inserted and pressed between a curved surface 36 of an inserting and pressing part 78 of one buff body and the curved surface 36 of the inserting and pressing part 78 of the other buff body provided on a cover body 58 side is rotated by following up a rotation of one buff body by frictional force against one buff body, and brought to relative rotation against the other buff body provided on the cover body 58 side. On the other hand, damping force for damping the rotation of the contact lens works on the contact lens due to frictional force against the other buff body, therefore, the contact lens 34 is brought to relative rotation against one buff body, as well, placed on its case body 10 side. In such a way, a prescribed scrubbing effect is always obtained.

Description

Detailed Description of the Invention (Technical Field) The present invention relates to a contact lens cleaning device for cleaning hard contact lenses and soft contact lenses. The present invention relates to a contact lens cleaning device that can extremely effectively and easily clean and remove stains such as oil, fat, and dust.

(Background Art) When wearing contact lenses, proteins and lipids that are secretions from the eye or dust in the air can stick to the lens surface, reducing the light transmittance of the lens and the feeling of wearing it. This is unavoidable, and it is necessary to periodically clean and remove dirt such as proteins, lipids, and dust that adhere to the lens.

For this purpose, as a cleaning device for cleaning and removing dirt from such contact lenses, (a)
Using an elastic board made from foamed silicone rubber,
A contact lens is placed on this elastic plate, a cleaning solution containing a surfactant as a main ingredient is added, and dirt on the lens surface is cleaned and removed by rubbing the surface of the contact lens against the elastic plate with a fingertip. (b) Place the contact lens in a holder, immerse it in a container containing a cleaning solution, stir and rotate the contact lens together with the holder using a stirring mechanism, and use the flowing action of the cleaning solution to remove dirt on the lens surface. (c) A so-called ultrasonic cleaner that uses ultrasonic energy to clean and remove dirt from the lens surface; (d) A pair of bottomed cylindrical bodies. Drop the cleaning solution onto the elastic pads placed inside the lens, place the contact lens between the elastic pads,
By relatively rotating a bottomed cylindrical body, an elastic pad is rubbed against the inner and outer surfaces of the contact lens to clean and remove dirt from both surfaces of the contact lens.
1295) etc. have been proposed.

However, all of these conventionally proposed cleaning devices have the following disadvantages, and the reality is that they are not necessarily desirable.

In other words, in the case of method (a) in which the contact lens is rubbed against an elastic plate with the fingertip, if the contact lens is a soft contact lens, there is a possibility that the fingernail will be pressed against the lens and cause tearing or cutting. If the contact lens is a hard contact lens, there is a risk that the lens may be scratched or cracked due to the nail being pressed against the lens. Moreover,
There is a problem that the strength of acupressure tends to vary due to individual differences, which tends to cause variations in the cleaning effect.In addition, if there is a fear of damaging the lens, sufficient acupressure strength cannot be obtained. There is also the problem that the cleaning effect cannot be obtained, and there is also the problem that both sides of the contact lens cannot be cleaned at the same time, and in the case of hard contact lenses, only the outer surface can be sufficiently cleaned.

In addition, in the type (b), in which dirt on the lens surface is cleaned and removed by the flowing action of the cleaning liquid caused by the stirring by the stirring mechanism, the contact lens is shaken within the holder. In addition to shaking off dirt on the surface, it breaks lipid dirt into lipid particles and disperses them into the cleaning solution.
The cleaning principle is that the adhesiveness of the surfactant in the cleaning solution absorbs dirt and releases and removes it from the lens surface.
It has the disadvantage that it has a low cleaning effect on protein and lipid stains that are firmly adhered to the lens surface, and that it takes a considerable amount of time to remove these protein and lipid stains.

Furthermore, although the ultrasonic cleaner shown in (C) has an extremely high cleaning effect, on the other hand, the vibration energy that releases dirt from the lens is extremely strong, so it is difficult to use the ultrasonic cleaner when using and handling hard contact lenses. Small scratches caused by the product are amplified by the powerful vibration energy, and with repeated use, they crack.

It has serious drawbacks such as developing into a crank, etc., and the structure including the control circuit for driving the ultrasonic transducer is complex, making it difficult to miniaturize, so compared to various contact lens accessories. It is unavoidable that the device is extremely large, and it also has problems such as being inconvenient to carry.

Also, the above publication (see Utility Model Publication No. 61-31295)
The contact lenses are cleaned by the rubbing action of elastic pads arranged on a pair of bottomed cylindrical bodies, as disclosed in
In the type d), the opposing surfaces of both elastic pads that sandwich the contact lens are substantially flat compared to the degree of curvature of the contact lens. There is a problem in that the pressing force of the elastic pad against the outer circumference and the center of the inner surface of the lens is small, and therefore the cleaning effect on the outer circumference and the center of the inner surface of the contact lens is extremely poor. There is also the problem that cleaning work is cumbersome and troublesome because it has to be turned by hand. Moreover, the contact lens is prevented from escaping between the elastic pads by the contact of the edge of the contact lens with the inner surface of the bottomed cylindrical body. There is also a risk that the edge of the contact lens may be damaged by contact.

(Problem to be solved) The present invention has been made against the background of the above, and its problem is to solve the problem when cleaning either hard contact lenses or soft contact lenses. It does not damage contact lenses even when exposed to contact lenses, has a relatively compact structure, and can easily clean and remove stains such as proteins, lipids, and dust stuck to contact lenses with extremely good and stable cleaning effects. Our goal is to provide a contact lens cleaning device that is capable of cleaning.

(Solution Means) In order to solve this problem, the contact lens cleaning device according to the present invention uses a clamp made of an elastic foam material having a curved surface substantially corresponding to the shape of one surface of the contact lens. and a pinching part of the first buff body that is brought into sliding contact with the first buff body at the peripheral edge thereof. A second buff body having a clamping part made of an elastic foam material having a curved surface is arranged on each of the case body and the lid body so that the oppositely curved surfaces of the buff bodies face each other. , when the lid body is covered with respect to the case body, the contact lens is compressed between the oppositely curved surfaces of the buff bodies, and an electric motor is disposed in the case body, and the case body The contact lens is configured to be able to rotate one buff body disposed on the side while pinching the contact lens between it and the other buff body disposed on the lid body side based on the rotational driving force of the electric motor. That's what I did.

Here, in the contact lens cleaning device according to the present invention, from the viewpoint of ease of handling, the first buff body is provided with a clamping portion having a concave surface corresponding to the external shape of the contact lens, and the case body side At the same time, a second buff body is disposed on the lid side, so that when cleaning contact lenses, the first buff body disposed on the case body side is disposed on the second buff body disposed on the lid body side. It is preferable that the concave surface of the first buff body is located on the lower side and opens upward.

In addition, the first and second buffing bodies can be pressed against both the inner and outer surfaces of the contact lens with a good pressing force to obtain a better cleaning effect and to reduce the degree of dirt on the inner and outer surfaces of the contact lens. In order to adjust the cleaning efficiency of the inner and outer surfaces of the contact lens accordingly, and thereby to efficiently clean the inner and outer surfaces of the contact lens, the radius of curvature of the curved surface of the pinching part of the buff body that is pressed against the inner surface of the contact lens should be adjusted. It is preferable to set it smaller than that of the curved surface of the pinching part of the buff body that is pressed against the outer surface of the contact lens. Note that it is also possible to make the hardness or coefficient of friction of the elastic foam material that constitutes the clamping part of the first buff body and the elastic foam material that composes the clamping part of the second buff body different from each other. In order to efficiently clean contact lenses by adjusting the cleaning efficiency for the inner and outer surfaces of the lens,
It is valid.

Furthermore, in order to more evenly clean each of the inner and outer surfaces of the contact lens, the curved surfaces of the pinching portion of the first buff body and the curved surfaces of the pinching portion of the second buff body are It is also possible to form them so that they face each other with a certain amount of eccentricity.

(Function/Effect) In the contact lens cleaning device configured as above,
When one buff body disposed on the case body side is rotated by an electric motor disposed on the case body, the curved surface of the clamping part of the one buff body and the clamping part of the other buff body disposed on the lid body side are connected. The contact lens, which is pressed between the curved surface of the pressure part, is rotated as the one buff body rotates due to the frictional force between the contact lens and the other buff body provided on the lid body side. It is rotated relative to the buff body. On the other hand, a braking force that brakes the rotation of the contact lens acts on the contact lens due to the frictional force between it and the other buff body provided on the lid side, so the rotation of the contact lens is on the case body side. As a result, the contact lens also rotates relative to the one buff body disposed on the case body side.

In other words, the pinching parts of both buff bodies made of elastic foam are pressed against the inner and outer surfaces of the contact lens with their respective curved surfaces, and are rotated relative to the contact lens. Due to the relative rotation of both buff bodies, proteins, lipids, dust, etc. that have adhered to the inner and outer surfaces of the contact lens are rubbed off from the inner and outer surfaces of the contact lens, released and removed from the contact lens, and the contact lens is cleaned. .

Here, in the present invention, the clamping part made of an elastic foam material of one buff body has a curved surface substantially corresponding to the surface shape of the contact lens with respect to one of the inner and outer surfaces of the contact lens. The elastic foam clamping part of the other buff body is pressed against the other surface of the contact lens with the opposite curved surface, and the contact lens is pressed against the other surface of the contact lens. Since the pressure is applied between the curved surfaces, both the inner and outer surfaces of the contact lens are well pressed by the elastic foam pinching parts of both buff bodies, and therefore the electric motor Based on the rotation of one of the buff bodies, dirt on the inner and outer surfaces of the contact lens can be cleaned and removed very effectively.

Further, in the present invention, the contact lens is rotated relative to the pinching portions of the buff bodies while the pinching portions of each buff body are pressed against both the inner and outer surfaces of the contact lens with a substantially constant pressing force. Since the dirt on the lens is cleaned and removed, the above-mentioned good cleaning effect can be obtained extremely stably. Moreover, such cleaning work is performed by rotating one buff body using an electric motor. Since cleaning is carried out on both the inner and outer surfaces of the contact lens at the same time, the cleaning operation can be performed extremely simply and easily, and the cleaning device can be configured to be sufficiently compact.

Furthermore, in the present invention, as described above, the soft pressing portions of each buff body made of elastic foam material are rubbed against the inner and outer surfaces of the contact lens, thereby cleaning the inner and outer surfaces of the contact lens. Therefore, damage to contact lenses, regardless of whether they are hard contact lenses or soft contact lenses, can be effectively avoided.

Further, in the present invention, since both buff bodies are brought into sliding contact with each other at the peripheral edges, the contact lens is prevented from popping out from between the pinching parts of both buff bodies, so that the edge of the contact lens is made of a hard material. Therefore, damage to the edge of the contact lens due to contact with a hard member is also effectively prevented.

By the way, in the contact lens cleaning device according to the present invention, when cleaning the contact lens, the cleaning liquid is supplied to the curved surface of the pinching part of each buff body that is pressed against the inner and outer surfaces of the contact lens. In the contact lens cleaning device according to the present invention, the first buff body is provided with a clamping portion having a concave surface substantially corresponding to the external shape of the contact lens, and this is disposed on the case body side, and when cleaning the contact lens. In this case, the first buff body disposed on the case body side is located below the second buff body disposed on the lid body side, such that the concave surface of the first buff body opens upward. This makes it possible to set the contact lens in the cleaning area reliably and easily, and when cleaning the contact lens, for example, after dropping the cleaning liquid onto the concave surface of the first buff body, the contact lens is placed on the concave surface. After setting the contact lens and dropping the cleaning solution again on the inner surface of the contact lens,
By making the lid cover the case body,
The cleaning liquid is reliably and effectively applied to the curved surface of the pinching part of each buff body.
Moreover, it can be easily added, and therefore its handling is extremely easy.

Further, in the contact lens cleaning device according to the present invention,
If the radius of curvature of the curved surface of the pinching part of the buff body that is pressed against the inner surface of the contact lens is set smaller than that of the curved surface of the pinching part of the buff body that is pressed against the outer surface of the contact lens, the inside and outside of the contact lens can be By pressing the pinching parts of the first and second buff bodies against both surfaces with a good pressing force, it is possible to obtain a good cleaning effect on both the inner and outer surfaces of the contact lens, and to adjust the radius of curvature. By doing this, the pressing force of the clamping part of each buff body against the inner and outer surfaces of the contact lens can be adjusted, so the cleaning efficiency for the inner and outer surfaces of the contact lens can be arbitrarily adjusted depending on the degree of dirt on the inner and outer surfaces of the contact lens. This makes it possible to efficiently clean the entire contact lens.

Furthermore, without adjusting the radius of curvature of the curved surface in the clamping part of such a buff body, the elastic foam material that constitutes the clamping part of the first buff body and the clamping part of the second buff body can be adjusted. Even if the hardness or friction coefficient of the contact lens and the elastic foam material are made to be different from each other, the cleaning efficiency of the inner and outer surfaces of the contact lens can be adjusted depending on the degree of dirt on the inner and outer surfaces of the contact lens. The hardness and coefficient of friction between the elastic foam material that makes up the clamping part of the first buff body and the elastic foam material that composes the clamping part of the second buff body depend on their materials, expansion ratio, and cell ( By changing the size of the bubbles, etc., you can change the frequency of the words.

Furthermore, in the contact lens cleaning device according to the present invention, the curved surface of the clamping part of the first buff body and the curved surface of the clamping part of the second buff body are arranged so that they are eccentric by a predetermined amount and face each other. If formed, the sliding contact position between the inner and outer surfaces of the contact lens and the curved surface of the pinching portion of each corresponding buff body will change as the contact lens and each buff body rotate relative to each other. It becomes possible to clean the inner and outer surfaces of the contact lens more evenly.

(Example) Hereinafter, in order to clarify the present invention more specifically,
Some embodiments thereof will be described in detail based on the drawings.

Further, here, an O made of silicone rubber or the like is provided between the output shaft 20 of the reducer 18 and the upper wall 16 of the case body 10.
A JJ song 7 is provided to maintain fluid tightness between the output shaft 20 of the reducer 18 and the earthen wall 16 of the case body 10.

A disc-shaped rotary disc 28 made of synthetic resin is concentrically fixed to the tip of the output shaft 20 of the reducer 18 that protrudes upward from the upper wall 16 of the case body 10. A disc-shaped lower buffing stand 30 made of synthetic resin is removably mounted on the disc 28 concentrically with the rotary disc 28. Then, on this lower buffing table 30, the lower buffing table 30
In addition, a lower buff 32 made of an elastic foam material and serving as a clamping part constituting the first buff body is removably disposed. A concave surface (curved surface) 36 substantially corresponding to the outer shape of the contact lens 34 is formed concentrically with the contact lens 20 .

As a result, the lower buff 32 disposed on the lower buff stand 30 is rotated to the center stripe of the concave surface 36 based on the rotational driving force of the motor 22.

Here, the rotary disk 2 has a cylindrical rib 3 extending upward.
7 on its outer periphery, and a mounting hole 38 in its center. It is forced to be inserted. And this male thread part 4
The peripheral edge of the mounting hole 38 is sandwiched between the nut 42 screwed into the threaded hole 42 and the stepped surface of the output shaft 20 formed at the base end of the male threaded portion 40, and the tip of the output shaft 20 is It is fixed concentrically to the

The lower buffing table 30 also includes a held portion 44 with an outer diameter lower than the inner diameter of the rib 37 of the rotary disk 28, and
The upper buff holding part 46 has a cylindrical structure with a bottom and a diameter larger than the outer diameter of the buff. A plurality of locking protrusions 48 formed on the inner surface of the rib 37 are locked in the mating recess, and the rib 37 is removably attached to the upper surface of the rotary disk 28 . Then, the lower part is accommodated in the buff holding part 46 of the lower buffing stand 30, and is adhered to the bottom surface of the buff holding part 46 with a predetermined adhesion means such as double-sided adhesive tape, so that the concave surface 36 is covered. The provided lower buff 32 is disposed on the lower buff stand 30.

Note that silicone rubber (SR) is preferably used as the raw material for the elastic foam material constituting the lower buff 32, but other raw materials, such as styrene-butadiene rubber (SBR) and nitrile-butadiene rubber, may also be used. Rubber (NBR),
Isoprene rubber (IR), butyl rubber (IIR),
Urethane rubber (UR), fluororubber (FR), acrylic rubber (AR).

It is also possible to use neoprene rubber, polysulfide rubber, etc., and it is also possible to use modified versions of two or more of the above rubbers, such as acrylic urethane rubber and urethane-modified silicone rubber.

Further, the concave surface 36 of the lower buff 32 is usually formed by grinding a foamed base material as the lower buff 32 using an abrasive material such as a grindstone.

By the way, on the upper surface of the upper wall 16 of the case body 10,
A cylindrical rib 52 of a predetermined height is erected to surround the rib 37 of the rotary disk 28, and a plurality of engagement members protruding from the inner circumferential surface are fitted into the rib 52 at the opening. The locking protrusion 54 is engaged with a plurality of engagement recesses formed on the outer peripheral surface of the rib 52, so that a bottomed cylindrical lid body 58 made of synthetic resin is removably attached to the case body 10. It has become.

The lid body 58 has a central hole 62 formed in the center of its bottom wall 60, and a cylindrical rib surrounding the central hole 62 on the inner surface of the bottom wall 60. 64
has been erected. Then, the rib 64 is fitted into the rib 64.
At the same time, a protrusion 66 formed protruding from the upper surface projects into and fits into the central hole 62 of the bottom wall 60 of the lid body 58, and is inserted into a plurality of notched recesses 72 formed at the outer periphery of the lower surface. An upper buffing stand 70 made of synthetic resin is arranged to be removably attached to the lid 58 by being locked with a plurality of locking pieces 74 provided at the tip of the rib 64 of the lid 58. ing. Then, the upper buffing table 70 is accommodated in a recess 68 formed on the lower surface of the upper buffing table 70, and the upper surface is adhered to the bottom surface of the recess 68 using adhesive means such as double-sided adhesive tape. An upper buff 78 is also disposed as a pinching portion constituting a second buff body.

The upper buff 78 is made of the same elastic foam material as the lower buff 32, and is fitted into the recess 68 of the upper buff stand 70 and has a diameter larger than the opening diameter of the concave surface 36 of the lower buff 32. an upper disk portion 80 having a slightly larger diameter; and a convex surface (curved surface) 84 whose tip end surface has a smaller radius of curvature than the concave surface 36 of the lower buff 32, extending concentrically downward from the upper disk portion 80. (See FIG. 3(a)). When the lid body 58 is attached to the case body lO as shown in FIG. 1, the center line of the convex surface 84 at the tip of the protrusion 82 is The upper buff 7 is adapted to be deformed by a predetermined amount and pressed against the inner surface of the contact lens 34 at the convex surface 84 at the tip of the protrusion 82 in a state that coincides with the center line of the concave surface 36 of the lower buff 32, Thereby, the upper buff 78 is brought into close contact with the inner surface of the contact lens 34 substantially evenly with a predetermined pressing force. In addition, a lid body 58 to the case body lO
In the covered state, as shown in FIG. 1 and FIG. The contact lens 34 is brought into contact with the annular flat part, as will be described later.
During cleaning, the contact lens 34 is prevented from popping out from between the upper buff 78 and the lower buff 32.

In addition, in the covered state of the lid body 58, the lower buff 32 is also deformed by a predetermined amount between the contact lens 34 and the lower buff stand 30, and as a result, the lower buff 3
2 is brought into close contact with the entire outer surface of the contact lens 34 substantially uniformly on the concave surface 36 with a predetermined pressing force.

Further, the radius of curvature of the convex surface 84 of the upper buff 78 is, when the contact lens 34 is a hard contact lens,
Since the lens is difficult to deform, the radius of curvature is usually set to about 4 to 7 W, which is smaller than the radius of curvature of the inner surface of the contact lens 34, but if the contact lens 34 is a soft contact lens, the lens is easily deformed. Therefore, the radius of curvature of the inner surface of the contact lens 34 may be slightly larger, and is usually set in a range of about 4 to 12 w.

Next, use such a cleaning device to clean the contact lenses 34.
The case of cleaning will be explained.

That is, when cleaning the contact lens 34, first, the lid body 58 is removed from the case body 1o, and an appropriate amount of cleaning liquid is dripped onto the concave surface 36 of the lower buff 32. Then, the contact lens 34 is placed on the center of the concave surface 36 of the lower buff 32 onto which the cleaning liquid has been dripped, with the outer surface facing down. An appropriate amount of cleaning liquid is dripped onto the inner surface again, and then the lid body 58 is attached to the case body 10. In other words, the contact lens 34 is compressed between the lower buff 32 and the upper buff 78. And those lower buff 32 and upper buff 7
With the contact lens 34 being squeezed between the
The power switch 24 is operated to rotate the motor 22.

When the motor 22 is rotationally driven, its rotational driving force is reduced by the reducer 18 and transmitted to the output shaft 20 of the reducer 18, and as a result, the lower buff 32 is rotated to the center stripe of the concave surface 36. . When the lower buff 32 is rotated, the contact lens 34 is moved from the lower buff 34 based on the frictional force acting between the lower buff 32 and the contact lens 34.
2 and rotated relative to the upper buff 78.

On the other hand, a frictional force between the contact lens 34 and the upper buff 78 acts on the contact lens 34 which is rotated in the same direction as the lower buff 32, and this frictional force acts as a braking force against the rotation of the contact lens 34. The rotational speed of the lower buff 32 is lower than that of the lower buff 32, and as a result, the contact lens 34 is also rotated relative to the lower buff 32.

That is, when the power switch 24 is operated to drive the motor 22 to rotate, the lower buff 32 and the upper buff 78 made of elastic foam that pinch the contact lens 34 are both rotated relative to the contact lens 34. The buffs 32 and 78 are rubbed against the contact lens 34 by the relative rotation operation, and dirt such as protein, lipid, dust, etc. stuck to the inner and outer surfaces of the contact lens 34 is rubbed off from the inner and outer surfaces of the contact lens 34. It is possible. Then, the dirt rubbed off from the contact lens 34 is adsorbed and removed by the surfactant in the cleaning liquid.

In addition, when cleaning the contact lens 34, the outer peripheral edge of the lower surface of the upper disc part 80 of the upper buff 78 comes into sliding contact with the annular flat part of the peripheral edge of the opening of the concave surface 36 of the lower buff 32. Therefore, the contact lens 34 pressed between the lower buff 32 and the upper buff 78 will not jump out from between the lower buff 32 and the upper buff 78, but As the area of the sliding surface between the upper buff 78 and the lower buff 32 increases, the resistance to rotation of the lower buff 32 also increases, so the width of the sliding surface between the upper buff 78 and the lower buff 32 is usually set to around 3 mm becomes.

Furthermore, when cleaning the contact lens 34, cleaning liquid is interposed between the inner and outer surfaces of the contact lens 34 and the lower buff 32 and upper buff 78, so the frictional force acting between them is It is relatively small, so the resistance to rotation of the lower buff 32 does not become so large, and it is possible to avoid the contact lens 34 from being fixed to either the lower buff 32 or the upper buff 78.

When a predetermined period of time (usually about 1 minute) has elapsed after the motor 22 started rotating based on the operation of the power switch 24,
Since cleaning of the contact lens 34 is completed, the operating section of the power switch 24 is operated again to stop the motor 22. After the motor 22 is stopped, the lid 58 is removed from the case body 10, the contact lens 34 is taken out, and rinsed. As a result, contact lens 3
The cleaning work in step 4 is completed.

In addition, the lower buff 3 used for cleaning the contact lenses 34
2 and the upper buff 78 can be used repeatedly by removing them together with the lower buffing stand 30 and the upper buffing stand 70, or by removing them from the case body 1O and the lid body 58 and washing them with water.

Here, in the cleaning device of this embodiment, as described above,
The lower buff 32 is pressed against the outer surface of the contact lens 34 with a concave surface 36 substantially corresponding to the outer surface shape of the contact lens 34, and the upper buff 78 is pressed against the outer surface of the contact lens 34 with a concave surface 36 substantially corresponding to the outer surface shape of the contact lens 34, and an upper buff 78 is pressed against the outer surface of the contact lens 34 with a concave surface 36 substantially corresponding to the outer surface shape of the contact lens 34, and an upper buff 78 is pressed against the outer surface of the contact lens 34 with a concave surface 36 substantially corresponding to the outer surface shape of the contact lens 34. The small convex surface 84 is pressed against the inner surface of the contact lens 34, and the concave surface 36 of the lower buff 32 and the convex surface 84 of the upper buff 7 are pressed against the outer and inner surfaces of the contact lens 34 with a predetermined pressing force, respectively. Since the buffs 32 and 78 are in close contact with each other, the rubbing action based on the relative rotation of the buffs 32 and 78 against the contact lens 34 effectively cleans and removes any dirt stuck to both surfaces of the contact lens 34. It is.

Further, in the cleaning device of this embodiment, as is clear from the above description, each buff 32.78 is compressed with a substantially constant amount of compression, that is, with a substantially constant pressing force against the contact lens 34. In the pressed state, those buffs 32.
78 is rotated relative to the contact lens 34, both buffs 32 relative to the contact lens 34
．． A good cleaning effect based on the relative rotation of the motor 78 can be obtained in an extremely stable manner, and such cleaning work is automatically performed based on the rotational driving force of the motor 22. Therefore, the cleaning work is extremely simple, and since the motor 22 itself can be small, the cleaning device can be configured to be sufficiently compact.

Furthermore, in the cleaning device of this embodiment, as mentioned above,
The soft lower buff 32 and lower buff 78, both made of elastic foam material, are rubbed against the inner and outer surfaces of the contact lens 34 to clean the inner and outer surfaces of the contact lens 34, so that the contact lens 34 becomes a hard contact lens. Damage to either the lens or the soft contact lens is effectively avoided, and the contact lens 34 is prevented from protruding from between the buffs 32.78 by touching the outer periphery of the buffs 32.78. Since the sliding contact between the parts is prevented, problems such as chipping of the edges of the contact lens 34 do not occur.

In addition, in the cleaning device of this embodiment, as described above, after the cleaning liquid is dropped onto the concave surface 36 of the lower buff 32, the concave surface 36 of the lower buff 32 is
The contact lens 34 is placed on the contact lens 6, and the cleaning liquid is dripped onto the inner surface of the contact lens 34 again, and the lid body 58 is covered with the case body 10, thereby forming a curved surface of the pinching part of each buff body. The cleaning liquid can be reliably, effectively, and easily supplied to the concave surface 36 of the lower buff 32 and the convex surface 84 of the upper buff 78, and the contact lens 34 can be It can be set reliably between the two, and its handling is extremely excellent.

By the way, in the cleaning device of this embodiment, as described above, the upper buff 78 and the lower buff 32 are rotated relative to each other while being pressed against the inner and outer surfaces of the contact lens 34. 32 is rubbed against the inner and outer surfaces of the contact lens 34, dirt on the inner and outer surfaces of the contact lens 34 is cleaned and removed. By adjusting the radius and the pressing state of the convex surface 84 of the upper buff 78 and the concave surface 36 of the lower buff 32 against the contact lens 34, the grinding ratio for dirt fixed on the inner and outer surfaces of the contact lens 34, that is, the contact It is possible to arbitrarily adjust the cleaning efficiency for the inner and outer surfaces of the lens 34, and therefore, knowing the dirt on the inner and outer surfaces of the contact lens 34, cleaning the concave surface 36

However, the cleaning efficiency for the inner and outer surfaces of the contact lens 34 does not necessarily need to be adjusted based on the adjustment (combination) of the radius of curvature of the convex surface 84 of the upper buff 78 and the concave surface 36 of the lower buff 32; The cleaning efficiency for the inner and outer surfaces of the contact lens 34 can be adjusted by adjusting the hardness of the upper buff 7 day and the lower buff 32 and the coefficient of friction against the contact lens 34 while keeping the contact lens 34 constant. It is possible to perform cleaning efficiently.

Incidentally, the hardness of the upper buff 78 and the lower buff 32 and the coefficient of friction against the contact lens 34 may be affected by using different materials as the raw materials for the elastic foam materials of the upper buff 78 and the lower buff 32, or by using different materials for the elastic foam materials of the upper buff 78 and the lower buff 32, or The lower buff 32 can be made different from each other by adjusting the expansion ratio and cell size of the elastic foam material that constitutes the lower buff 32.

However, the hardness of the elastic foam material constituting the upper buff 78 and the lower buff 32 is usually selected within the range of 5 to 60" as measured by a sponge hardness meter (Asuka C), and The expansion ratio (specific gravity before foaming/specific gravity after foaming) is usually selected in the range of about 1.5 to 6 times.Also, the cell size is usually 0.2 to 2 mm.
Although the size of the bubbles is selected, the bubbles do not necessarily have to be independent, but may be continuous, in which the bubbles communicate with each other.

Next, another embodiment of the present invention will be described based on FIG. Components that have the same functions as those in the embodiment described above are designated by the same reference numerals as those in the embodiment described above, and detailed explanations thereof will be omitted.

That is, in the washer shown in FIG. 4, a thick-walled cylindrical portion 86 is integrally provided on the outer circumference of the upper surface of the upper wall 16 of the case body 10, and the outer circumference of the thick-walled cylindrical portion 86 on the tip side The lid body 58 is fitted into an annular notch 88 formed in the annular notch 88 so that it can be detachably attached.

The lid body 58 is prevented from being removed.

Here, a reducer 18 is fixedly installed on the upper wall 16 of the case body 10 via a mounting plate 94, and the motor disposed below the reducer 18, as in the previous embodiment. The rotational driving force of 22 is reduced in speed and transmitted to the output shaft 20 of this reducer. Here, a battery 26 that rotationally drives the motor 22 is inserted vertically into the case body 10 and arranged.

Note that the motor 22 is started and stopped by a power switch (not shown) similar to the previous embodiment.

Unlike the embodiment described above, a female threaded hole 96 is formed at the tip of the output shaft 20 of the reducer.
A rotary disk 2 in the shape of a cylinder with an upward opening and a bottom is attached concentrically to the output shaft 20 by a male screw 98 screwed into the output shaft 20 . The held portion 44 is housed in a recess 100 opened on the upper surface of the rotary disk 28, and a lower buffing stand 30 is removably attached thereto.

The lower buff 32 is attached to the curved surface of the recess 102 of the lower buffing table 30 by a predetermined attachment means, with its end surface being flush with the upper surface of the lower buffing table 30. ing.

Further, here, a cylindrical rib 104 is formed on the outer circumference of the lower buffing stand 30 in a state extending downward, and on the upper surface of the inner circumference of the cylindrical portion 86 of the case body 10, The rib 104 of the lower buffing table 30 and the rotary disk 28
The cylindrical rib 106 extends between the outer circumference of the
is formed. As a result, a labyrinth 108 is formed between the rotary disk 28, the lower buffing table 30, and the case body 10 to prevent water or the like from entering the inside of the cylindrical portion 88.

The rotary disk 2 is fixed by a plurality of bolts 112 to a plate 110 which is held under pressure between the end surface of the output shaft 20 of the reducer 18 and the head of the male screw 98.

On the other hand, the lid body 58 has the center hole 6 in the embodiment.
2 is not formed, but a cylindrical rib 64 similar to that of the previous embodiment is formed on the lower surface of the bottom wall 60.

An upper buffing stand 70 having a cylindrical shape with a bottom and opening on the lower surface is removably housed in a recess 114 surrounded by ribs 64, and inside the recess opening on the lower surface of the upper buffing stand 70. An upper buff 78 having a structure similar to that of the previous embodiment is disposed in which the upper disk portion 80 is housed. As a result, in a state where the lid body 58 is attached to the case body IO, the upper buff 7

6, they are both pressed substantially equally with a predetermined pressing force.

In addition, as shown in FIG. 4, the upper buffing stand 70 is
When the lid body 58 is attached to the case body 10, the outward flange portion 115 provided at the opening thereof is slidably brought into contact with the upper surface of the lower buff stand 30 and the end surface of the lower buff 32. Further, the upper buff 78 attached to the upper buff stand 70 is configured such that the outer peripheral edge of the lower surface of the upper cylindrical portion 80 is brought into contact with the end surface of the lower buff 32 by a predetermined width, as in the previous embodiment. It has become. When the lower buff stand 30 and the lower buff 32 are rotated based on the rotational driving force of the motor 22, the upper buff stand 70 and the upper buff 78 slide against the upper surface of the lower buff stand 30 and the end surface of the lower buff 32. This prevents the contact lens 34 from popping out from between the upper buff 78 and the lower buff 32.

Further, here, the upper buffing table 30 is configured so that the plurality of engagement protrusions 116 protrudingly formed on the back surface of the flange portion 115 are engaged with notch recesses formed at the tips of the ribs 64 of the lid body 58. This prevents the upper buff stand 70 and, by extension, the upper buff 78 attached to the upper buff stand 70 from rotating with respect to the lid body 58.

For example, in the embodiment described above, the concave surface 36, which is a curved surface substantially corresponding to the outer shape of the contact lens 34, is provided on the pinching part (lower buff 32) of the first buff body disposed on the case body 10 side. At the same time, a convex surface 84, which is a curved surface opposite to the concave surface 36, is formed on the pinching part (upper buff 78) of the second buff body disposed on the lid body 58 side. During cleaning, the concave surface 36 of the clamping part of the first buff body disposed on the case body 10 side is positioned below the convex surface 84 of the clamping part of the second buff body disposed on the lid body 58 side. Although the concave surface 36 was forced to open upward, it is also possible to provide the concave surface 36 and the convex surface 84 at the pinching portions of the buff body on opposite sides,
Also, both buff bodies having the concave surface 36 and the convex surface 84,
Furthermore, it is also possible to reverse the vertical relationship between the case body 10 and the lid body 58, and furthermore, the convex surface 84 can be made into a curved surface that substantially corresponds to the inner surface shape of the contact lens 34, or the convex surface 84 and It is also possible that both the concave surface 36 and the concave surface 36 are curved surfaces that substantially correspond to the surface shape of the contact lens 34 . Note that when the convex surface 84 is a curved surface corresponding to the inner surface shape of the contact lens 34, the radius of curvature of the concave surface 36 is , usually 8-20

By doing so, the position of sliding contact between the inner and outer surfaces of the contact lens 34 and the curved surfaces of the pinching parts of the corresponding buff bodies changes with the relative rotation between the contact lens 34 and both buff bodies. Therefore, there is an advantage that the inner and outer surfaces of the contact lens 34 can be cleaned more evenly.

Furthermore, in the embodiment described above, the battery 26 was used as a power source for the motor 22, but it is also possible to use a household AC power source, a rechargeable battery, or the like as a power source for the electric motor.

Further, in the embodiment, the motor 22 as an electric motor is
All of these devices are started and stopped by operating a power switch (24), and the driving period of the motor 22 is determined mainly by the user's intuition. It is also possible to define the period using a timer circuit or other timing device. In this way, there is an advantage that a constant cleaning effect can always be expected, and there is also an advantage that there is no need to worry about the time when cleaning the contact lens 34, and furthermore, there is no need to worry about the time when cleaning the contact lens 34, and furthermore, there is no need to use electricity due to forgetting to turn off the power. Problems such as consuming
There is also the advantage that it can be easily avoided.
