Description

Nail grinding device special for feet

Technical Field

The utility model relates to a nail grinding device special for hands and feet.

Background

Props for trimming/manicuring nails of hands and feet (so-called nail clippers) are used more than 1000 years ago. In japan, scissors-type or pliers-type nail clippers are said to appear about 100 years ago, and the clip-type nail clippers, which are most popular at present, appear about 80 years ago. The operation of cutting toenails with these nail clippers is not easy for the elderly or the disabled who do not easily perform the actions/postures such as tilting the upper body forward, bending the legs, and drawing the feet close to the upper body. Therefore, problems frequently occur such as skin injury due to pinching of the nail without sufficient visual recognition of the toe or the hand tip, and failure to trim the nail to a desired length. It is sometimes difficult to cut nails themselves because the nail blades do not follow the shape or gap of the deformed or hardened nails.

As a tool for easily coping left and right fingernails in a short time regardless of the dominant hand, an electric nail polisher is used. Portable electric manicures are most common today. Such a portable electric nail polisher is basically composed of a power switch, a battery, a motor, a motion conversion mechanism, and a polishing section, and when it is used, the polishing section vibrates or rotates at a high speed in conjunction with the driving of the motor. The user grinds the nail surface by bringing the vibrating or rotating polishing portion into contact with the nail surface.

Examples of portable electric nail polishers are disclosed in document 1 (japanese utility model registration No. 3218108) and document 2 (japanese patent table 2018-. These are all battery-type and the whole can carry at any time and any place. In addition, it is assumed that the nail polisher is used by being held by one hand and brought into contact with the finger on the other side.

The nail polisher described in the above document 1 is assumed to be used exclusively for polishing fingernails. When it is intended to be applied to toenails, the following problems are encountered in the same way as the above nail clippers: toenails or grinding heads are covered by the held hands or handles and the grinding condition is difficult to observe, or the toe nails are not endurable by long-term toenail grinding because the hands and feet are brought together and an unreasonable posture is obtained. The above document 2 roughly describes that toenails can also be polished, but it is obvious that the same problem as in the case of the document 1 occurs in the typical example shown in the drawings. Thus, the portable electric nail polisher is not a convenient tool for polishing toenails.

Several proposals have been made so far regarding nail polishers for the foot, which are attempted to solve the problem of polishing toenails. In the nail polisher described in document 3 (japanese patent application laid-open No. 2014-180493), the main body and the battery housing portion are separately provided, so that the nail polisher can move in a narrow space between the toenail and the toenail of the foot. However, even in this case, if the nail polisher is moved by holding a small body with a hand, the following problems remain: the toenail or the grinding head is covered by the hand or the body held by the hand or the body and the ground state is difficult to observe, or the toe nail is not endurable by an unreasonable posture in which the hand and the foot are closed. Document 4 (international publication WO 2010/064380) describes that slits or corners are provided in a polishing portion to facilitate polishing of toenails, but in a typical example shown in the drawings, since the polishing portion is close to a grip portion of a main body, a problem that long-term toenail thinning is not tolerated due to an unreasonable posture of closing hands and feet is not solved.

Document 5 (jp 2004-436 a) describes a nail grinding device for grinding or polishing a toenail in a comfortable posture without damaging the toe tip. The nail grinding device brings the grinder into contact with the toenails in a state where the feet are placed on the support plate and the tips of the toes are covered with the protection plate. When using the nail polish device, it is not necessary to take a painful position by gathering the feet and hands, and the contact point of the polish with the toes is easily observed. However, such an armor grinding apparatus is large in scale and is not suitable for carrying at all. Also, there is a problem that the operation of such an armor grinding apparatus is itself complicated.

As such, a small and convenient nail clipper for foot, which can be operated while any one can observe the grinding part in a comfortable posture, has not been known.

Detailed Description

The utility model discloses a special first ware of grinding of foot comprises rectangular main part and grinding head. The polishing head is provided with a polishing part. The term "long" in the present invention means a body that is remarkably longer than a conventional nail polisher, and specifically means a length that allows a user to easily bring a polishing head into contact with a toenail to be polished while holding the body. In other words, the "long strip" of the present invention is a length exceeding the length assumed in the conventional nail polisher for hands and feet, and is a length unnecessary in the conventional nail polisher assumed to be applied exclusively to fingers. In this sense, the present invention provides a "rectangular main body" for distinguishing the prior art and the features of the present invention, in view of the prior art in this technical field, "rectangular" is an explicit definition.

The user brings the polishing portion into contact with the toenail while holding the main body. The polishing head is driven by a motor, and the polishing part moves at a high speed.

The present invention can integrate the long main body with the polishing head having a predetermined length, and can set the length of the long main body to be adjustable. The foot-specific manicure device of the present invention is also epoch-making in terms of the manner in which the length of the main body can be adjusted. The present invention is directed to a toe nail polishing device in which a length of a main body is set to a "long" shape for polishing a toe nail, and a user can hold the main body in a comfortable posture while bringing a polishing portion into contact with the toe nail.

The mechanism for adjusting the length of the body is not limited if the strength and operability of the body, the ease of gripping, and a certain degree of design can be ensured. For example, attachment or detachment of accessories, extraction or enclosure of kits, movement of slides, and the like may be used. If the adjustment mechanism is miniaturized when the special nail polisher for feet is not used, the nail polisher is convenient to carry or accommodate.

In the case of adjusting the length of the main body by attachment or detachment of the accessories, for example, a plurality of accessories are prepared as the main body part. In this example, the user selects the number of accessories according to the location and posture sense of manicuring the toenail, and holds the long body to which the necessary members are connected.

When the length of the main body is adjusted by extracting or enclosing the set, for example, the following configuration is adopted: the combination of a plurality of coaxial tubular members having different inner diameters allows the other tube to be accommodated inside the tube having the largest inner diameter, and the inner tube to be extended toward the end of the outer tube, thereby fixing each tube in the extended state. In this example, the user holds the elongated body at a position corresponding to the portion thinning the toenail and the posture feeling.

In the case of adjusting the length of the main body by the movement of the slider, the main body is constituted, for example, by elongate members sliding with respect to each other with a stopper. In this example, the user slides the long members to each other according to the region and the posture feeling of the manicure toenail, and holds the long body having an appropriate length.

Fig. 1 schematically shows the structure of the nail polisher 1 for foot of the present invention in which the length of the main body 2 is the longest. The nail polisher 1 for foot is composed of a main body 2 and a polishing head 3, and an arrow indicates the movement direction of the polishing head 3. The main body 2 includes a portion (an extension member 5) extended by an appropriate method. In fig. 1, the upper surface of the polishing head 3 is shown, and a polishing portion attached to one surface of the polishing head 3 is not shown. The shape and size of each member are merely examples, and the features of the present invention are not limited to those shown in fig. 1. The special nail polisher for feet is suitable for polishing toenails 6. The user holds the body 1, brings the polishing head 3 close to the toe of the foot 4, and can polish the toenail by bringing the polishing portion, which moves at a high speed with the polishing head 3, into contact with the toenail 6. By holding the body 2 at an appropriate position, the user can dress the toenail in a comfortable posture while visually confirming the positional relationship between the toenail 6 and the grinding head 3 or the ground portion of the toenail.

The material of the main body is not limited as long as the operability of the main body is not impaired. As a main material, general-purpose plastics having a small specific gravity and excellent moldability are generally used. The main body portion can also be decorated by adding a colorant, printing, vapor deposition, adhesion of a decorative member, or the like.

Fig. 2 schematically shows a condition in which the polishing head 3 is provided with the polishing section 7 in the nail polisher for foot according to the present invention. The polishing head 3 and the polishing section 7 are viewed from the side. The lower side is a grinding part 7. The shapes and sizes of the polishing head 3 and the polishing section 7 are merely examples, and the features of the present invention are not limited to those shown in fig. 2.

The shapes of the grinding head and the grinding part are not limited as long as the operability of the nail polisher special for feet is not damaged. For safety, the polishing head and the tip of the polishing section are preferably rounded. By adopting such a rounded shape, the polishing head and the polishing portion can polish the toenail without damaging the toes. For ease of handling, it is preferable that the polishing head and the polishing section are tapered, for example. By providing such a taper shape, the tip of the polishing portion can be brought into contact with the toenail end, and the fine part of the toe can be ground.

The structure and the grinding material of the grinding part of the nail polisher special for feet are not limited. The structure may be any of a plate shape, a cloth paper shape, a nonwoven fabric, and the like, and various natural materials such as ceramics, metals, and wood materials can be used as the abrasive.

One example of the polishing portion of the present invention is a glass file. The glass file has a grinding surface formed on at least a part of a plate-like glass. The glass file is thin and can be easily cut into a shape matching the surface shape of the polishing head, and therefore the polishing head and the polishing section can be made compact. The mohs hardness of glass is about 5 and the mohs hardness of human toenails is about 2.5. Therefore, when the polishing portion moving at a high speed is brought into contact with the surface of the toenail, only the toenail is polished, and the glass file constituting the polishing portion is hardly deformed or abraded.

The polishing effect of the glass file depends on the shape of the irregularities, i.e., the depth of the irregularities and the interval between the irregularities. The degree of such unevenness can be quantified as "surface roughness". The glass file having a large surface roughness functions as a so-called "coarse" abrasive material. The glass file having a small surface roughness functions as a so-called "fine" abrasive material. In general, various glass files having a surface roughness of 10 μm or more and 100 μm or less as defined in JIS B0031 and JIS B0601 can be used. The utility model discloses in, can also use the glass file that is provided with metal levels such as chromium on the surface. The metal layer is formed by vapor deposition or the like.

The method of attaching the polishing section to the polishing head is not limited in the present invention. In general, a method of embedding a polishing portion in a frame provided in a polishing head, a method of bonding one surface of a polishing head and a flat surface of a glass file with a curable adhesive, and the like are used.

The utility model discloses in, can establish the grinding head into interchangeable. The user can select the most suitable polishing head from among polishing heads having polishing portions with different surface roughness according to the stage of polishing toenails.

The movement direction of the grinding head of the utility model is not limited as long as the movement direction or the period of the toenail grinding of the grinding part is suitable. That is, the direction of the distal end of the polishing head and the direction of the distal end of the main body may be connected to each other, the polishing head may be reciprocated in the width direction, and these reciprocations may be switched as appropriate.

The utility model discloses a special first ware that grinds of foot can also further be used for protecting the lid of grinding head or be used for acceping holistic shell etc. by the subsidiary.

The mode of driving the motor and supplying power for controlling the movement of the polishing head of the present invention is not limited as long as it can be used for a general nail polisher dedicated to feet. A motor and power switch, a battery, a charger, a power cord, etc., which can be used for the foot-specific nail polisher, may be used.
