Description

TECHNICAL FIELD The present invention relates to a cat's nail polishing/grinding device. More particularly, the present invention relates to a cat's claw polisher/grinder capable of simultaneously polishing and grinding a cat's claws.

Cats have a habit of polishing their nails to remove the old outer layer of nails. Polishing of a cat's claws is generally referred to as cat claw sharpening, cat claw polishing, or the like. Cat claw sharpening is a cat's habit, so when cats are raised in a general household, cats sharpen their claws on the walls, pillars, furniture, etc. in the room, so it is not recommended to sharpen the claws on the wall. can be injured by cats.

In order to prevent cats from sharpening their claws on walls, pillars, furniture, etc. in a room, in recent years, as a cat claw sharpener for sharpening claws, for example, multiple sheets of corrugated cardboard are laminated and glued. A lamination section or a wavy bent portion of the laminated corrugated cardboard formed by the method is used as a polishing portion for nail sharpening, and the laminated corrugated cardboard is detachably stored in a case so that the polished portion is exposed to the outside, A cat's claw sharpener has been proposed which has a paper piece storage section in the case (see, for example, claim 1 of Patent Document 1).

However, when using the cat claw sharpener, even if the cat's claws can be sharpened, the sharp tip of the cat's claws cannot be ground. It is not possible to completely suppress the act of scratching the wall surface by sharpening the nail by standing up.

Therefore, even if the above cat claw sharpener is used, it is necessary to cut the cat's claws separately from sharpening the cat's claws. When you try to cut a cat's claws, you may be injured by being scratched or bitten by the cat.

Therefore, as a nail sharpener that can be reduced by polishing a cat's claws, a nail polishing material laminated cardboard or linen cloth coated with an abrasive material on the back side is placed between a core base such as a wooden board or laminated cardboard. A cat claw sharpener with an abrasive material has been proposed, which has a function of pinching and fixing to sharpen the claws (see, for example, claim 1 of Patent Document 2).

However, as shown in FIGS. 1 and 2 of Patent Document 2, the cat's claw sharpener with an abrasive includes laminated cardboard or linen cloth 4, abrasive 2, wooden board or laminated cardboard 1 in order from the surface. , abrasive material 3, and laminated cardboard or hemp cloth 5 are provided. is not exposed to the outside, so it is not possible to grind a cat's claws under normal use. In addition, even if the abrasive material 2 is exposed to the outside by scratching and tearing the laminated cardboard or linen cloth 4, which is the surface layer of the cat claw sharpener with abrasive material, the abrasive material 2 remains rough. Since the pads of the cat's front paws (balls of the palm) and toes of the cat rub against the adhered surface, the cat instinctively avoids the nail sharpener and stops using it.

As another cat claw sharpener, there has been proposed a cat claw sharpener in which a cardboard and a grit (sand) layer are laminated in direct contact (see, for example, Patent Document 3). Also, in FIG. 3 of Patent Document 3, a corrugated board 25 composed of a corrugated board sheet 40 and a liner 30 is in direct contact with a grit (sand) layer 100 in which sand particles 150 are sandwiched between two backing sheets 110. 4-8, a strip of sandpaper 160 with sand particles 180 attached to a backing sheet 170 is sandwiched between two liners 30. A cat claw sharpener is described that is laminated with

However, in the cat claw sharpener described in FIGS. 4, 7 and 8 of Patent Document 3, the surface of the sandpaper piece 160 to which the sand particles 180 are attached is covered with the backing sheet 110. , the cat's claws cannot be efficiently ground. In the cat's claw sharpener shown in FIG. 5, the surface of the sandpaper piece 160 to which the sand particles 180 are attached is covered with the seal sheet 190, so the cat's claws cannot be efficiently ground. In the cat's claw sharpener shown in FIG. 6, the surfaces of the paper pieces 160 to which the sand particles 180 are attached are stacked, so the cat's claws cannot be efficiently ground.

Therefore, it is conceivable to make the sandpaper piece 160 project higher than the surface of the liner 30 in order to grind the cat's claws in the cat's claw sharpener. However, when the sandpaper piece 160 protrudes beyond the surface of the liner 30, the protruding sandpaper piece 160 contacts the paw pads of the cat's sole, and the cat contacts the paw pads with the sandpaper piece 160. Since the cat's claw sharpener is disliked, the cat's claw sharpener is no longer used, and the cat's claw sharpener cannot sufficiently exhibit the cat's claw sharpening effect.

Also, in the cat claw sharpener, the sandpaper piece 160 is placed flush with the liner 30 so that the sandpaper piece 160 does not come into contact with the cat's paw pads. Alternatively, laminating the sandpaper piece 160 and the liner 30 with the sandpaper piece 160 recessed from the surface of the liner 30 is contemplated. In either case, however, the cat's claws cannot be efficiently ground because the cat's claws do not catch on the pieces of sandpaper.

Therefore, in recent years, the development of a cat's nail polisher/grinder that can polish the nails of cats and efficiently grind the tips of the nails has been eagerly awaited.

In addition, the cat's claw enters the space between the grinding member and the core, and the cat's toe is ground by the grinding surface of the grinding member existing in the space. can be done.

Therefore, when the cat's nail polisher/grinder of the present invention is used for a cat, the cat polishes the nail by itself and grinds the tip of the nail, so that it is troublesome for a human to cut the cat's nail with a conventional nail clipper. In addition, since it eliminates the need for work that cats dislike, the cat claw polishing/grinding device of the present invention is very useful for cat owners.

In the present invention, the upper surface of the cat's nail polishing/grinding device is the surface (polishing/grinding surface) on which the cat's nails are polished and ground in the cat's nail polishing/grinding device. Polishing/grinding of cat's claw means polishing and grinding of cat's claw.

A polishing surface for polishing a cat's nail is formed on the upper surface of the cat's nail polishing/grinding device of the present invention. The polishing surface is formed by the end surface of the grinding member, the corrugated end surface of the core, and the end surface of the liner, which are present on the upper surface of the cat's claw polishing/grinding device.

The grinding member has a grinding surface for grinding cat claws on at least one side thereof. The grinding surface may be formed only on one side surface of the grinding member, or may be formed on both side surfaces of the grinding member. From the viewpoint of efficiently grinding the cat's claws, it is preferable that the grinding surfaces are formed on both sides of the grinding member.

The grinding surface of the grinding member may be a surface to which an abrasive is attached, or may be a surface having unevenness capable of grinding a cat's claw.

Examples of the grinding member include a grinding member having a grinding surface formed by attaching an abrasive to a base material, a metal file, and the like. From the viewpoint of reducing the weight of the cat's claw polishing/grinding device of the present invention, the polishing member is preferably a polishing member having an abrasive adhered to a substrate.

Abrasives used in the grinding member include, for example, natural abrasives such as sand, and artificial abrasives such as alumina particles and silicon carbide particles, but the present invention is limited by the type of such abrasives. not a thing The particle size of the abrasive is specified in R6010.

Substrates used for grinding members include, for example, paper, woven fabric, non-woven fabric, wood board, resin board such as vinyl chloride resin, polyester, acrylic resin, and polypropylene, and foamed resin (sponge) board such as acrylic foam and polyurethane foam. , chloroprene rubber, styrene-butadiene rubber and other rubber plates, and metal plates, but the present invention is not limited to these examples.

Examples of the grinding member include abrasive paper (sandpaper) specified in JIS R6252, in which paper is used as the substrate; abrasive cloth (rubber cloth), specified in JIS R6251 in which cloth is used as the substrate; Water-resistant abrasive paper (water-resistant (sand) paper) specified in R6253; Grinding with abrasives (abrasive particles) attached to the surface of substrates such as wood plates, resin plates, foamed resin (sponge) plates, rubber plates, and metal plates Examples include members and the like, but the present invention is not limited only to such examples. The grinding member is preferably abrasive paper (sandpaper), abrasive cloth or waterproof abrasive paper, more preferably abrasive cloth or waterproof abrasive paper.

When a grinding member such as abrasive paper, abrasive cloth, or waterproof abrasive paper is used as the grinding member, for example, the abrasive member is folded in two so that the surface on which the abrasive is adhered is exposed to the outside. A polishing member in which the inner surfaces of the folded grinding member are attached to each other with a double-sided adhesive tape, an adhesive, etc., a base material having elasticity such as sponge or rubber on the inner surface of the grinding member folded in two, and a resin plate , a polishing member having a laminated structure in which a reinforcing material such as cardboard is sandwiched and the grinding member and the reinforcing material are bonded together, a double-sided adhesive tape on one or both sides of an elastic base material such as sponge or rubber, It can be used in the form of a grinding member having a laminated structure in which grinding members are bonded together with an adhesive or the like. A grinding member having a laminated structure in which grinding members are bonded to one side or both sides of an elastic base material has elasticity based on the base material having elasticity on the surface, so that the grinding surface does not feel like a cat. It has the advantage that the tip of the nail can be easily caught. The grinding member preferably has a plate-like shape from the viewpoint of efficiently grinding and grinding cat's claws.

The roughness specified in JIS R6010 of the abrasive adhering to the surface of the grinding member is not particularly limited. It is preferably about No. 60 to 1000, more preferably about No. 80 to 600, and even more preferably about No. 100 to 240.

The grinding member has a grinding surface on at least one side surface so that the cat's claw rubs against the upper surface of the cat's nail polishing/grinding device to efficiently polish and grind the cat's nail. The grinding member may also have a grinding surface on its upper surface. From the viewpoint of efficiently polishing and grinding the cat's claws even when the cat's nail polisher/grinder is used with the upside down direction reversed toward the plane of the cat's nail polisher/grinder, the grinding surface is: It is preferably provided on both side surfaces of the grinding member, and more preferably provided on the upper surface and both side surfaces of the grinding member.

In the plane of the cat's claw polishing/grinding device, the planar shape of the grinding member is preferably linear from the viewpoint of efficiently polishing/grinding the cat's claws without giving discomfort to the cat. The linear shape includes, for example, a linear shape, a curved shape, a wavy shape, and the like, but the present invention is not limited by such a linear shape. The planar shape of the grinding member is preferably linear from the viewpoint of facilitating the manufacture of a cat's claw polishing/grinding device and efficient polishing/grinding of cat's claws. The line width of the linear grinding member varies depending on the type of grinding member, and cannot be determined in a general manner. The line width of the linear grinding member maintains the mechanical strength of the grinding member when the cat scratches the upper surface of the cat's claw polishing/grinding device, efficiently polishes and grinds the cat's claws, and also maintains the cat's claws. From the viewpoint of not giving discomfort to the body, the thickness is preferably 0.5 to 5 mm, more preferably 0.5 to 3 mm, and even more preferably 0.8 to 1.5 mm. The length of the grinding member on the plane of the cat's nail polisher/grinder differs depending on the shape and size of the cat's nail polisher/grinder, so it cannot be determined indiscriminately. It is preferable to appropriately determine the shape and size of the nail polisher/grinder.

The grinding member may be formed over the entire width of the cat's nail polishing/grinding device, or may be formed in the central portion of the cat's nail polishing/grinding device. They may be formed scattered here and there, and the present invention is not limited by the arrangement of the grinding members in the cat's claw polisher/grinder. From the viewpoint of efficiently polishing/grinding the cat's claws, the grinding member is preferably formed over the entire width of the cat's claw polishing/grinding device or in the vicinity thereof.

The cat claw polishing/grinding device of the present invention has a grinding member, a core having a plurality of corrugated sides, and a liner. The grinding member, core and liner are preferably positioned on the cat's claw sander/grinder with their respective faces perpendicular to the plane of the cat's claw sander/grinder.

On the upper surface of the cat's claw polishing/grinding device of the present invention (the flat surface of the cat's claw polishing/grinding device), there are the end faces of the grinding member, the corrugated end face of the core, and the end faces of the liner, A space based on the corrugated shape of the core exists between the grinding surface provided on the side surface of the grinding member and the side surface of the core, and the space communicates with the upper surface of the cat's claw polishing/grinding device. Therefore, when a cat raises its claws and scratches the upper surface of the cat's claw polishing/grinding device, the tip of the cat's claws are caught by the grinding member, the core and the liner, and thus are polished, and the space in question is also polished. It is ground because it rubs against the grinding surface of the grinding member present in the inner surface.

Liners generally used for cardboard can be used as the liner. The liner usually has a planar shape, but it may have a curved shape, a corrugated shape, or other shape within a range that does not hinder the object of the present invention. The ground surface may be formed by adhering the abrasive material to the side surface of the liner or by attaching an abrasive material such as abrasive paper (sandpaper). When a grinding surface is formed on the side surface of the liner, the cat's claw rubs against the grinding surface, so the cat's claw can be efficiently ground. The grinding surfaces may be provided on one side or both sides of the liner, but are preferably provided on both sides of the liner from the viewpoint of efficiently grinding the cat's claws.

As the core, a core generally used for cardboard can be used. The core has a plurality of wavy shapes. Examples of the corrugated shape of the corrugated core include the corrugated shape of the corrugated core used for corrugated cardboard defined in JIS Z1516 (2003), but the present invention is not limited to such examples. do not have.

Since the number of liners and cores varies depending on the shape and size of the cat's nail polisher/grinder, it cannot be determined indiscriminately. It is preferable to determine it as appropriate according to the degree of difficulty and the like.

The abrasive member, core and liner can be integrated by gluing the respective contacts together.

The surface on which the end surface of the grinding member, the corrugated end surface of the center core, and the end surface of the liner are present is the polishing/grinding surface of the cat's claw. Further, the surface on which the end surface of the grinding member does not exist, and on which the corrugated end surface of the core and the end surface of the liner exist, is the polishing surface of the cat's claw.

The surface on which the end surface of the grinding member, the corrugated end surface of the core, and the end surface of the liner exist (polishing/grinding surface) may be formed only on the upper surface of the cat's claw polishing/grinding device. , may be formed on both the upper surface and the lower surface of the cat's claw polishing/grinding device.

The end face of the grinding member, the corrugated end face of the center core and the end face of the liner (polishing / grinding surface) are the upper surfaces of the cat's nail polishing / grinding machine (cat's nail polishing / grinding machine ), the lower surface (the back surface of the cat's claw polishing/grinding device) does not have the end surface of the grinding member, and has the corrugated end surface of the core and the liner It may be a surface (abrasive surface) on which an end surface exists, for example, there is no end surface of a grinding member, an end surface having a corrugated shape of a core, or an end surface of a liner, such as a paper surface. It may be flat.

The bottom surface of the cat's claw polishing/grinding device (the back surface of the cat's claw polishing/grinding device) does not have the end face of the grinding member, and has the corrugated end face of the center core and the end face of the liner. If the surface (polished surface) is a cat nail, polish/grind the cat's claws with the top surface of the cat's claw polisher/grinder (flat surface of the cat's nail polisher/grinder), and do not grind the cat's nails. When polishing, the cat's claw polishing/grinding device is turned over, and the cat's claw can be polished on the lower surface of the cat's nail polishing/grinding device (the back surface of the cat's nail polishing/grinding device). In this way, the lower surface of the cat's claw polishing/grinding device (the back surface of the cat's claw polishing/grinding device) does not have the end face of the grinding member, and the end face having the corrugated shape of the core and the end face of the liner. If the cat's claw is on the surface (polished surface), the cat's claws may be excessively damaged by using the upper surface of the cat's nail polisher/grinder (flat surface of the cat's nail polisher/grinder). Before being ground, the cat's nail polishing/grinding device is turned upside down, and the surface (polishing surface) where the corrugated end face of the core and the end face of the liner exist (polishing surface) is polished/grinded. Excessive grinding of the cat's claws can be prevented by using the upper surface of the container (the flat surface of the cat's claw polishing/grinding device).

Therefore, after the cat has finished grinding the cat's claws using the cat's nail polisher/grinder of the present invention, the cat can use the cat's nail polisher/grinder to polish the cat's nails. From the viewpoint of being able to continue the above, the upper surface of the cat's claw polishing/grinding device (the flat surface of the cat's claw polishing/grinding device) is the end surface of the grinding member, the corrugated end surface of the center core, and the liner is the surface where the end surface of the grinding member exists (polishing/grinding surface), and the bottom surface of the cat's claw polishing/grinding device (the back surface of the cat's claw polishing/grinding device) is where the end surface of the grinding member does not exist. , the corrugated end face of the core and the end face of the liner (polished face).

In addition, when the end face of the grinding member, the corrugated end face of the core, and the end face of the liner are formed on both the upper and lower surfaces of the cat's claw polishing/grinding device, the upper surface is damaged by the cat's claw. By turning over the upper surface and the lower surface, the lower surface of the cat's nail polisher/grinder can be effectively used, so that the service life of the cat's nail polisher/grinder can be extended.

There are individual differences in the direction in which cats like to scratch the top surface of the cat's claw polishing/grinding device with their claws. Therefore, from the viewpoint of efficiently polishing and grinding the cat's claws, the side surface of the grinding member of the cat's nail polisher/grinder is arranged to cross the direction in which the upper surface of the cat's nail polisher/grinder is scratched with the claw. It is preferable to arrange it in the direction of The direction intersecting with the cat's scratching direction means the direction perpendicular to the cat's claw-scratching direction and the direction slightly oblique to the cat's claw-scratching direction. From the viewpoint of efficiently polishing and grinding the cat's claws, the liner of the cat's claw polisher/grinder is preferably provided in a direction parallel to the scratching direction of the cat's claws. The direction parallel to the cat's scratching direction means a direction parallel to the cat's scratching direction and a slightly oblique direction to the cat's scratching direction.
