Description

The present invention relates to a pet accessory that can be put on and taken off by a pet through its body hair, and particularly relates to a pet hair ring that is easily put on and taken off, although it is strongly held with a holding force by a pair of magnetic joints that form a magnetic circuit on the pet's body hair.

Pet accessories are trending these days. However, ribbons or collars are the mainstream, and there is no custom of wearing them on pet fur. The reason for this is that when worn on the ears, the animal's habit is to try to remove it. Therefore, it is desired to provide an accessory that cannot be easily removed due to the pet's habitual movements, but when attempting to attach it to the pet's body fur with a clip or the like, it is difficult to adjust the attachment strength. If it is too strong, there is a risk that the hair will fall out and damage your pet, while if it is too weak, it will easily come off due to your pet's movements and be lost. Therefore, a plan has been proposed to grip and attach a pet's body hair using a pair of magnets (Patent Document 1), but attachment to the pet's body hair is difficult due to the following points.
i) Unlike humans, dogs move vigorously, and if the body hair is pinched too much, it will easily come off and look bad (Patent Document 1). Therefore, if the bonding surface is made larger as a pair of discs and the suction force is increased (Patent Document 2), it will be difficult to remove them.
ii) Therefore, if a neodymium magnet is used and the pair of magnetically bonded bodies are made small, and the magnetically bonded bodies are directly adhered to each other, sufficient adsorption force to grip the pet's body hair cannot be obtained (Patent Document 3).

The adhesion force between magnets is important for attachment to pet hair, but it is difficult to make the magnetic bonding surface small enough to look good as an accessory and have enough strength to hold it. It is difficult to make it easy to put on and take off when having a. Therefore, it is desired to provide a pet accessory that has an appropriate clamping force for gripping the pet's body hair even if the magnetic joint part is small, and that can be easily attached and detached by a bending operation.

Therefore, as a result of intensive research, the inventor of the present invention made the joint surface of a pair of magnetic joints as narrow as 0.5 mmφ to 1 mmφ, and created an adsorption force F (surface magnetic flux density B x adsorption force of 0.2 to 1.0 kgf). In the case of sandwiching pet hair with an area S), 1) at least one of the pair of magnetically bonded bodies is composed of a rare earth magnet, preferably a neodymium magnet, and the pair of magnetically bonded bodies are formed into a rod shape to form a yoke. It is necessary to bond the bonding surfaces by surrounding them with the body to form a magnetic circuit MC, and 2) at least one of the bonding surfaces of the pair of magnetically bonded bodies is provided with a slip prevention surface having a coefficient of friction μ against body hair. It is necessary to apply not only magnetic attraction force but also a constant friction coefficient μ to the joint surface, and to exhibit a synergistic effect between the attraction force F and the friction coefficient μ. If the structure is such that at least one of the magnetic joints is separated by pinching and bending it in the bending direction with respect to the axis that connects the magnetic joints, even if it is a strong magnetic joint that is difficult to slip, it can be relatively easily separated by the action of bending. I discovered that it can be done. The present invention is based on this knowledge, and in view of the fact that it is necessary to set the jeweled part 11a visible from the outside on the front side body 11 of the pair of magnetically joined bodies so as to overlap the magnetically joined body 11b, FIG. 2(a) and As shown in (b), when stacking the jewelry part 11a and the magnetically bonded body 11b as the front side body, the jig containing them is used as the yoke body 11c, and the yoke body is assembled with the magnetic force bonded body 12a of the other back side body. 11c, it forms a magnetic circuit MC1 with the flow of magnetic lines of force shown in Figure 2(a), and allows the rare earth magnets including small neodymium magnets to firmly hold the pet's fur, while at the same time holding the back body to the length. They discovered that if they were made into a rod shape of 5 mm or more, the pair of joined bodies could be separated by bending as shown in FIGS. 3 and 7(a) and 7(b), and the present invention was completed.

That is, the present invention is a hair link that is a pet accessory that is attached to a pet while holding the pet's body hair. A magnetic joint part 10 is made up of a rod-shaped front side magnetic joint body 11 and a rod-shaped back side magnetic joint body 12 that are butted against each other and attracted to each other, and the front side magnetic joint body 11 is suspended via a chain or the like, and is visible from the outside when attached to a pet.

It is made of a neodymium magnet that exhibits a magnetic characteristic of an attraction force F (surface magnetic flux density B x attraction area S) of 0.2 or more and 1.0 kgf or less when held in a sandwiched state.
D) (Fourth feature) The rod-shaped magnetic force bonded body 11b and the rod-shaped magnetic force bonded body 12a are arranged so that lines of magnetic force are connected to each other through the cylindrical yoke body 11c or through both the cylindrical yoke body 11c and the cylindrical yoke body 12b. forming a flowing magnetic circuit MC1 or 2;
E) (Fifth feature) The pair of magnet joints 11 and 12 has a slip having a friction coefficient μ on the joint surface of one or both of them to prevent the gripping portion from slipping against the pet hair to be held. Has a prevention surface,
F) (Sixth feature) The pair of magnetically bonded bodies 11 and 12 prevents the magnetically bonded portion 10 from being removed from body hair pinched by the motion of the pet due to the synergistic effect of the attraction force F and the friction coefficient μ of the anti-slip surface. While having the desired body hair clamping strength μ×F that does not fall out,
G) (Seventh feature) The pair of magnetically joined bodies 11 and 12 are magnetically joined by a force in a direction that bends the back side magnetically joined body 12 with respect to an axis L passing through the center of both bodies. A pet hair ring characterized by being detachable and detachable.
Furthermore, in the present invention, the pair of magnetic force joints 11 and 12 is a magnetic circuit MC1 formed by the yoke body 11c of the front body 11 shown in FIG. It is preferable to form the magnetic circuit MC2 shown in FIG. 7(b) by both of the yoke bodies 12b, and it is preferable that they are further laminated with a magnetic metal pedestal interposed therebetween.
Furthermore, in the case of the magnetic circuits MC1 and MC2, as shown in FIG. 6(c), the back side magnetic force joint 12 is surrounded by a silicone rubber cover 12c, and an annular part for removal is provided at or near the rear end. 11e is preferably formed.

According to the present invention, as shown in Fig. 1, when attached to the subauricular body hair, it is difficult to reach, and even when attached to a pet's body hair, it is difficult to come off due to the animal's habitual movement, and it does not harm the animal. We can provide pet accessories, so-called hair rings.

According to the present invention, 1) It has a magnetic flux density B of at least 3000 Gauss or more at a thickness of 3 mm, and its joint surface has a joint area S of 5 mmφ to 10 mmφ and 0.2 or more and 1.0 kgf or less when body hair is sandwiched; To provide an accessory that can be called a hair ring, which exhibits magnetic properties with an adsorption force F (surface magnetic flux density B x adsorption area S) preferably of 0.3 or more and 0.8 kgf, and is ideal for holding and attaching the body hair of a pet. I can do it.
Although we have found that it is not advisable to use adhesives or adhesive clips to attach accessories through a pet's fur, and prefer to use magnetic force, we have found that using magnets is still an appropriate means for pet accessories. required many experiments. One is that when attaching accessories, it is necessary to manually attach and detach them. Considering the shape of the attachment part, the joint surface is usually about 0.25 ^cm2 , and at most 1.0 ^cm2 , it is necessary to join by magnetic force. It has been found that the strength needs to be 0.2 kgf or more and 1 kgf or less, preferably 0.3 kgf or more and 0.8 kgf or less. This adsorption force through the body hair is related to the magnetic flux density of the magnet, and if this adsorption force is exerted considering the density of the body hair held by the magnetic flux density of 3000 Gauss, preferably 4000 Gauss, the animal's habit. It was found that the hair gripping force that does not injure the animal can be obtained through motion.

2) In addition, in consideration of the strength of the magnetic force, it has been learned that in order to strengthen the magnetic bonding, it is good to provide the magnetic bonding surface with a predetermined coefficient of friction μ against body hair. Based on such experiments, body hair gripping force μ×F is determined by the synergistic effect of the friction coefficient μ of the magnetic joint surface and the attraction force F of the magnetic joint surface, and by adjusting the body hair gripping force μ×F, accessories can be attached via body hair. We have developed a pet accessory that can be attached with the appropriate strength to prevent injury to the animal, and that will not come off even when the animal does its habitual movements.

3) When the pair of magnetically joined bodies 11 and 12 form magnetic circuits MC1 and MC2 shown in FIGS. 7(a) and 7(b), the magnetic attraction force of the pair of magnetically joined bodies 11 and 12 can be reinforced.

4) Also, as shown in FIG. 6(c), if the back side bodies 12 of the pair of magnetically joined bodies are surrounded with silicone rubber 12e and a removal annular part 11e is provided at or near the rear end, the back side body 12 can be easily separated from the front body 11 by applying a bending force to the axes of the pair of magnetically joined bodies 11 and 12.

This pet hair ring is characterized in that the pair of magnetic joints 11 and 12 can be separated and separated by force.

Specifically, one or both of the joint surfaces of the pair of magnetic joints 11 and 12 should preferably form a slip prevention surface with a friction coefficient μ so as to reinforce the adsorption force, as shown in FIG. 5(a). As shown in FIG. It is preferable to use a metal concave-convex complementary joining surface, a concave-convex complementary part that engages with each other from parallel grooves and convex lines, or 2) a concave-convex complementary part that engages with each other from concentric concave grooves and convex lines. Also, 3) It is preferable to ensure a constant coefficient of friction by having the unevenness engage with each other in a wavy portion or in a zigzag shape so that a plurality of unevenness engages with each other. Alternatively, 4) one concave portion and one convex portion may loosely fit into each other and engage with each other, or a plurality of circular protrusions may be arranged so as to engage with each other to form a slip prevention portion.

As a magnet, it is necessary to obtain a predetermined magnetic force of 3000 Gauss, preferably a magnetic flux density of 4000 Gauss or more on a small joint surface, for example, a magnet joint surface of 5 to 10 mmφ, and it is recommended to use a so-called rare earth magnet.

It is preferable to form the circuit MC1 or MC2. When forming the magnetic circuit MC2, sufficient magnetic attraction can be achieved even if a Samakoba magnet is used instead of a neodymium stone. When using neodymium magnets, cylindrical neodymium magnets (manufactured by NeoMag) such as N52, N45, N40, N40SH, N40UH, N35H, and N35SH can be used. Both of the pair of magnetic force joints 11 and 12 may be made of magnets, or one may be made of a magnet and the other may be made of a magnetic metal.

It is preferable that the magnet form a columnar rod-like body because it can be bent and separated from the axis formed by the pair of magnetic joints 11 and 12. Since neodymium magnets are prone to rust, they are surrounded by a yoke body. Or, it is surrounded by silicone rubber, etc. In the case of a yoke body, it is best to plate it with a precious metal to give it a jeweled appearance.

When surrounding the magnet body with silicone rubber 12c, as shown in FIGS. 8(a) and 8(b), it is formed into a cylindrical shape, and as shown in FIG. It is preferable to provide a groove 12g around the periphery so that the magnet body 12a can be accommodated, and to provide an annular flange 12d at or near the rear end.
