Description

A pet hair ring that is attached to your pet's hair

[0001] The present invention relates to a pet accessory that is attached to a pet via its hair, and in particular to a hair ring that is detachably attached to the pet's hair by a clamping force due to magnetic and / or physical bonding using a pair of connecting bodies joined at their tips.

[0002] Pet accessories have become popular recently. However, most are attached by ribbons or collars, and there is no custom of attaching them to pets' fur. This is because, when attached to the ears, animals have a natural tendency to remove them. Therefore, there is a need for accessories that do not easily come off due to pet behavior. However, attaching accessories to pet fur using clips or other attachment methods presents a problem: it is difficult to adjust the attachment strength. That is, if the attachment is too strong, the hair may come off and injure the pet, while if it is too weak, the attachment may easily come off due to the pet's movements and be lost. Therefore, instead of clips, a proposal has been made to attach accessories by gripping the pet's fur with a pair of magnets (Patent Document 1). However, attaching accessories to pet fur presents several challenges: (1) Unlike humans, dogs' movements are intense, and when gripping the hair, the magnets must be large enough to easily come off (Patent Document 1). Therefore, if a pair of connecting bodies is made disc-shaped to increase the bonding surface and the adhesive force (Patent Document 2), the attachment becomes unsightly and difficult to remove. (2) Therefore, even if a rare earth magnet with strong magnetic force is used, simply bonding the tips of a pair of magnetically coupled bodies directly to each other does not provide sufficient adhesive force to grip pet hair (Patent Document 3).

[0003] Jitsobori No. 3095928 Publication JP 9-326311 JP 2007-14644 Problem to be solved by the invention

[0004] Therefore, the inventors have found that in the case of a pet hair ring, which is a pet accessory that is attached to a pet by clamping its hair, if appearance is important, it is desirable to have a pair of front and back joining bodies that clamp the pet's hair joined together with their tips butted against each other. In consideration of this point, and as a result of extensive research, it was found that when attaching by clamping the hair with a pair of connecting members, it is essential to have a structure having a connecting part 10 consisting of a front connecting member 11 and a back connecting member 12, and an ornamental part 20 such as jewelry attached to the front connecting member 11 that is visible from the outside when attached. In this structure, it was found that the connecting part consisting of the pair of connecting members needs to have the following functions for attaching to a pet, in order to achieve quick attachment when clamping the hair and attaching it immediately to a moving pet when gripping the hair: 1) a first function to center the tips of the pair of connecting members, and to maintain the joined state of the pair of butted connecting members, 2) a second function to lock the joined state of the pair of connecting members, and further to prevent the hair from falling out of the pinched hair, and 3) a third function to prevent the pet's hair from falling out of the pet's hair gripped by the pair of connecting members. The first function, centering, is achieved by the attractive force between magnets, but it is difficult to provide sufficient strength when clamping the magnets by reducing the magnetic contact surface to make them look attractive as accessories, and the second locking function is insufficient. On the other hand, if sufficient clamping force is required, it is difficult to make the accessories easy to attach and detach. Therefore, it is desirable to provide a pet accessory that has the appropriate clamping force for gripping pet hair while also being easy to attach and detach. Means to solve the problem

[0005] Therefore, as a result of extensive research, the inventors have found that when a magnetic joining method for a pair of joined bodies is adopted, the joining surfaces of the pair of magnetic joined bodies are narrow, ranging from 0.5 mm to 1 mm in diameter, and the pair of magnetic joined bodies exhibit magnetic properties of an adhesive force F (surface magnetic flux density B x adhesive area S) of 0.2 to 1.0 kgf so as to firmly hold the hair, while in order to separate the pair of joined surfaces, 1) at least one of the pair of rod-shaped magnetic joined bodies must be made of a rare earth magnet, preferably a neo-magnet, and 2) the pair of magnetic joined bodies must be formed into a rod shape and surrounded by a yoke body to join the ends together to provide a second locking function, and then 3) at least one of the pair of joined surfaces must be formed with an anti-slip surface for the hair to provide a third anti-slip function, and the pair of magnetic joined bodies must be formed into a rod shape and at least one of the magnetic joined bodies must be pinched and bent in the bending direction relative to the axis connecting the pair of magnetic joined bodies to separate them, thereby making it possible to relatively easily separate even a strong magnetic joined body.

[0006] On the other hand, when a magnetic joining structure is not used, a structure in which a pair of joined bodies are fitted together by movement in the axial direction is desirable to provide the first centering function, but in order to provide the second locking function after moving them in the axial direction, considering the function of clamping the body hair with the pair of joined bodies, a structure in which the pair of joined bodies are moved relatively around the axis to lock the axial movement is desirable rather than a screw structure, and this alone posed a problem as to how to configure an anti-slip function for the clamped body hair.The inventors have discovered that when having a centering function by movement in the axial direction and a locking function by relative movement around the axis, applying a biasing force in the axial direction opposite to that when the pair of joined bodies are joined reinforces the locking function and provides an anti-slip function for the body hair clamped at the joint.

[0007] Based on this finding, the present invention considers that when a pair of joined bodies are magnetically joined, it is necessary to set a jewelry part that can be seen from the outside on the front body of the pair of magnetically joined bodies, and when the jewelry part and the magnetically joined body are stacked to form the front body, the jig containing the magnetically joined body and the satiation part is made into a cylindrical body with a yoke function, and the yoke body is sandwiched between the magnetically joined body of the other back body, magnetic circuits MC1 and MC2 with the flow of magnetic lines of force shown in Figures 2(a) and 2(b) are formed, and it was found that if a rare earth magnet including a small neodymium magnet is used to firmly hold the pet animal's body hair, while if the back body is made into a rod-like shape of 5 mm or more that can be pinched with fingers, the pair of joined bodies can be separated by bending it, and thus the first invention was completed.

[0008] On the other hand, when joining by physical engagement, it is essential to cover the pair of joined bodies with a cylindrical body and design it so that they fit together and engage with each other through axial movement, which facilitates centering, the first function (see Figures 10(a) and 10(b)). If the pair of cylindrical bodies are designed to be locked by rotating relative to each other about their axes (see Figure 10(c)), axial movement of the pair of cylindrical bodies is prevented, fulfilling the second function. Furthermore, if at least one of the cylindrical bodies contains an elastic body such as silicone rubber, the pair of cylindrical bodies will maintain a locked state by an axial biasing force, preventing the pair of cylindrical bodies from coming off. Furthermore, the fitting of the pair of cylindrical bodies maintains the function of clamping body hair (see Figure 10(e)). This discovery led to the completion of the second invention.

[0009] Furthermore, we discovered that by combining the above physical joining and magnetic joining, it is possible to achieve the first centering function, the second locking function, and the third anti-hair slip function with a simple configuration through the joint work of both, and thus completed the third invention.

[0010] That is, the first invention is a pet hair ring, which is a pet accessory that is attached to a pet by holding the pet's hair, and comprises a joint 10 consisting of a front joint 11 and a back joint 12, a pair of front and back joints that hold the pet's hair and are joined together with their tips butted against each other, and a decorative part such as jewelry that is attached to the front joint 11 and is visible from the outside when attached, and the joint consisting of the pair of joints has the following functions necessary for attachment to the pet: a first centering function that holds the hair and aligns the center of the pair of joints by holding the hair when holding it, a second locking function that locks the joined state of the pair of joints, and a third fall-off prevention function that prevents the pet's hair from falling off at the pair of joints, and in this pet hair ring, when it is magnetically joined, A) the front joint 11 of the joint is configured such that a jewelry body 11a such as a gemstone and a magnetic joint 11b are stacked and contained within a cylindrical body 10c, B) the back-side joint 12 on the opposite side of the front-side joint 12 has a magnetic joint 12a enclosed in a cylindrical body 12b and formed into a rod-like shape with a length that can be held with fingertips, C) at least one of the magnetic joints 11b, 12a is 3 mm thick and has a magnetic flux density B of at least 3000 gauss or more, and its joint surface is made of a rare earth magnet including a neodymium magnet that has a joint area S of 5 mmφ to 10 mmφ and exhibits magnetic characteristics of an adhesive force F (surface magnetic flux density B x adhesive area S) of 0.2 to 1.0 kgf when holding body hair, and the magnetic field lines of the pair of joints provide the first centering function, D) the front magnetic assembly 11b and the back magnetic assembly 12a form a magnetic circuit MC1 or MC2 in which magnetic lines of force flow by sandwiching the cylindrical yoke body 11c or via both the cylindrical yoke body 11c and the cylindrical yoke body 12b, and a second locking function is provided in which the strength of the magnetic lines at the pair of joints locks the pair of joints to prevent them from separating; E) the pair of magnetic assemblies 11 and 12 have an anti-slip surface on one or both of their joint surfaces with a friction coefficient μ that prevents the pet hair being held therebetween from slipping against the joint surface; and F) the pair of assemblies 11 and 12 have a desired hair clamping strength μ×F that prevents the joint 10 from falling off from the held hair due to the pet's movements due to the synergistic effect of the attraction force F and the friction coefficient μ of the anti-slip surface, and the third anti-hair fall function is provided;G) A pet hair ring characterized in that the pair of magnetic joints 11 and 12 can be separated and detached by a force in the direction of bending the back joint 12 relative to an axis L passing through the center of both the pair of magnetic joints 11 and 12.

[0011] Next, in a second invention, there is provided a pet hair ring, which is a pet accessory that is attached to a pet by clamping its hair, and which comprises a joint 110 consisting of a front joint 111 and a back joint 112, a pair of front and back joints that clamp the pet's hair and are joined together with their tips butted against each other, and a decorative part such as a jewel attached to the front joint 11 that is visible from the outside when attached, and the joint consisting of the pair of joints has the following functions necessary for attachment to the pet: a first centering function of clamping the hair and aligning the center of the pair of joints when gripping the hair, a second locking function of locking the joined state of the pair of joints, and a third anti-fall function of preventing the pet's hair from falling out at the pair of joints, and in this pet hair ring, when the first to third functions are achieved by physical joining, A) the front joint 111 of the joint is configured to contain and store at least a jewel or other decorative part 111a within a cylindrical body 111c, B) The back-side joined body 112 on the opposite side of the front-side joined body is configured to contain an elastic body G that biases the axial direction of the cylindrical body 111c in one of the cylindrical bodies, preferably the cylindrical body 112b, and is formed into a rod shape that can be held with fingertips, for example, with a length of 5 mm or more; C) A pair of front and back joined bodies 111,D) the cylindrical bodies 111c and 112b of the pair of joined bodies are provided with second engaging portions 111e and 112f that prevent axial movement by relative movement around the axis, and have a second locking function that prevents the pair of cylindrical bodies 111c and 112b from separating in the axial direction, and E) The pair of cylindrical bodies 111c, 112b increase or decrease the depth of the joint in the axial direction of the engaging portions 111e, 112f by relative movement around the axis, and are urged in the axial direction by the elastic body 112a, providing a third anti-slip function that prevents the pet's hair from slipping out at the pair of joints; F) The pair of joints 111, 112 can be unlocked by rotating them relatively about the axis L that passes through the center of both bodies, allowing the joints to be separated and detached.

[0012] Furthermore, in a third invention, there is provided a pet hair ring, an accessory that is attached to a pet by clamping its hair, comprising a joint 110 consisting of a pair of front and back joints, front and back, that clamp the pet's hair and are joined together with their tips butted against each other, and a decorative part such as jewelry that is attached to front joint 111 and is visible from the outside when attached. Joint 110 consisting of a pair of joints has the following functions necessary for attachment to a pet: 1) a first centering function that clamps the hair when gripping it and aligns the center of the pair of joints, 2) a second locking function that locks the joined state of the pair of joints, and 3) a third anti-fall function that prevents the pet's hair from falling out of the pair of joints. In performing these functions with a physical joining configuration and a magnetic line joining configuration, A) The front-side joining body 111 of the joining part is configured by stacking a jewelry body 111a such as a gemstone and a magnetic joining body 111b, and containing and storing them in a cylindrical body 110c, while B) The back-side joining body 12 on the opposite side of the front-side joining body is configured by containing a magnetic joining body 12a in a cylindrical body 12b and forming it into a rod-like shape long enough to be held with fingertips, while C) The pair of front and back joining bodies 111, 112 have first engaging portions 111d, 112e that fit together by axial movement of the cylindrical body 111c and the cylindrical body 112b, and are configured to be joined via the first engaging portions, and the magnetic joining of the pair of magnetic joining bodies 111, 112 and the first engaging portions perform the first centering function, while D) The cylindrical bodies 111c, 112b of the pair of joined bodies have second engagement portions 111e, 112f that prevent axial movement by relative movement around the axis, and perform a second locking function that prevents the pair of cylindrical bodies 111c, 112b from separating in the axial direction; and E) The pair of cylindrical bodies 111c, 112b are urged in the axial direction by the magnetic joining force of the pair of magnetic joined bodies 111, 112 as well as by relative movement around the axis, and have a third anti-slip function that prevents the pair of joined bodies from falling out of the pet's hair at the pair of joined bodies; and F) The pair of joined bodies 11 and 12 can be unlocked by rotating them relatively about the axis L that passes through the center of both bodies, thereby separating the joined bodies and allowing them to be separated.

[0013] According to the present invention, firstly, an attractive looking pet accessory can be provided by comprising a pair of joints 10, 110 consisting of a front joint 11, 111 and a back joint 12, 112, which are joined together at their tips and which hold the pet's hair, and a decorative part such as jewelry attached to the front joints 11, 111, which can be seen from the outside when attached (see Figures 1(a) and (b)). Furthermore, secondly, in a pet hair ring consisting of a pair of joined bodies, the joints consisting of the pair of joined bodies have the functions necessary for attaching to a pet: a first centering function that aligns the center of the pair of joined bodies by pinching the hair when gripping it; a second locking function that locks the joined state of the pair of joined bodies; and a third fall-off prevention function that prevents the hair from falling out of the pet's hair at the pair of joined bodies.Therefore, the ring can be attached with a single touch to the hair of a pet that moves around a lot, and the locking function and hair fall-off function prevent the hair from falling out of the pet's hair.

[0014] In particular, the magnetic attachment method of the first invention has a magnetic flux density B of at least 3,000 gauss at a thickness of 3 mm, and its attachment surface has a bonding area S of 5 mm to 10 mm, and exhibits magnetic characteristics of an adhesive force F (surface magnetic flux density B x adhesive area S) of 0.2 to 1.0 kgf, preferably 0.3 to 0.8 kgf, when clamping the hair, making it possible to provide an accessory that can be called a hair ring, which is ideal for clamping and attaching to pet hair. It was found that the use of adhesives or adhesive clips is undesirable for attaching accessories via pet hair, and that magnetic force is preferable, but even when using magnets, much experimentation was required to find an appropriate method for pet accessories. One of the reasons for this is that the attachment surface is usually 0.25 cm thick, considering the shape of the attachment part, which is necessary for manual attachment and detachment. ２ At most 1.0 cm ２It was found that the magnetic attachment strength must be between 0.2 kgf and 1 kgf, preferably between 0.3 kgf and 0.8 kgf. The adhesive force via hair is related to the magnetic flux density of the magnet. It was found that if this adhesive force is exerted taking into account the density of the hair to be clamped with a magnetic flux density of 3000 gauss, preferably 4000 gauss, a hair-gripping force that will not injure the animal even during its habitual behavior can be obtained. Furthermore, it was found that, taking into account the magnetic force strength, a predetermined friction coefficient μ between the magnetic attachment surface and the hair can be provided to strengthen the magnetic attachment. Based on these experiments, the hair-gripping force μ×F is determined by the synergistic effect of the friction coefficient μ of the magnetic attachment surface and the adhesive force F of the magnetic attachment surface. By adjusting the hair-gripping force μ×F, the accessory can be attached via the hair with the desired strength that will not injure the animal, and a pet accessory that will not come off even during the animal's habitual behavior can be provided.

[0015] 2(b) , the magnetic circuit MC2 formed between the magnetic members 11 and 12 can reinforce the magnetic attraction of the magnetic members 11 and 12. Furthermore, if the rear body 12 of the magnetic members is surrounded by silicone rubber 12e and a detachable annular portion 11e is provided at or near the rear end, the magnetic members 11 and 12 can be easily detached by bending the magnetic members 11 and 12 along their axes.

[0016] One or both of the joining surfaces of the pair of magnetic joints of the present invention preferably have a slip prevention surface with a friction coefficient μ to reinforce the adhesive force. The joining surfaces may be provided with a rubber viscoelastic layer made of silicone resin or synthetic resin, or may be made of a metal concave-convex complementary joining surface, a complementary concave-convex portion formed by parallel grooves and ridges, or a complementary concave-convex portion formed by concentric grooves and ridges. The concave-convex portions may be interlocked by wavy portions or zigzag portions, ensuring a constant friction coefficient. Thin plates such as silicone rubber may also be used. Alternatively, one concave portion and one convex portion may be interlocked with loose fit, or multiple circular protrusions may be interlocked to form the slip prevention surface.

[0017] The magnet must have a small interface, e.g., a diameter of 5 to 10 mm, to achieve a magnetic flux density of 3,000 gauss, preferably 4,000 gauss or greater. Therefore, rare earth magnets are recommended. Neodymium magnets are particularly useful, and they are used with the yoke body 11c of the front body 11 or the cylindrical yoke bodies 11c and 11b of the front body 11 and the back body 12 to form magnetic circuits MC1 and MC2 that ensure an appropriate flow of magnetic lines of force in both magnetically coupled bodies. When forming magnetic circuit MC2, samarium-cobalt magnets can be used instead of neodymium quartz to achieve sufficient magnetic attraction. When using neodymium magnets, cylindrical neodymium magnets (manufactured by NeoMag) such as N52, N45, N40, N40SH, N40UH, N35H, and N35SH can be used. The magnet is preferably in the form of a columnar rod with a diameter of 5 mm to 10 mm, and a jewel or other decorative part can be attached to the other end surface of the joining surface.

[0018] According to the second aspect of the present invention, the first centering function, the second locking function, and the third anti-slip function can be achieved by physical joining, similar to the magnetic joining method. In particular, the first centering function of the pair of cylindrical bodies constituting the pair of joined bodies is achieved by fitting them together in the axial direction, so that separation in the axial direction can be easily locked by relative movement around the axis, and the axial biasing force of the elastic body prevents the locking function from being released by the animal's movement.

[0019] According to the third invention, the first centering function, the second locking function, and the third anti-slip function can be achieved by combining physical and magnetic bonding. Compared to a case where only physical bonding is used, the first centering function, the second locking function, and the third anti-slip function can be reinforced, so the magnetic bonding structure of the first invention can be simplified. Furthermore, since the physical bonding can be reinforced by the magnetic bonding, not only can the magnetic bonding structure be simplified, but there is also no need to provide an elastic body, which is essential for physical bonding.

[0021] The present invention comprises a magnetic connector 10 consisting of a pair of rod-shaped magnetic connectors 11 and 12, and a jewelry part 20 suspended from the magnetic connector 10 by a chain or the like. As shown in Fig. 1, the magnetic connector 10 is attached to the pet's hair below the ear, and the jewelry part 20 is suspended from the magnetic connector 10 via a chain or the like. Fig. 2(a) is a perspective view showing an exploded and assembled state of a first embodiment of the pet hair ring of the present invention, and Fig. 2(b) is a perspective view showing an exploded and assembled state of a second embodiment of the pet hair ring of the present invention. In the first and second embodiments, the front body 11 is formed by enclosing the jewelry part 11a and the magnetic connector 11b within a cylindrical yoke body 11c. In the first embodiment, the rear body 12 is formed by enclosing the magnetic connector 12a with a rubber cover 12c, and the pair of magnetic connectors 11 and 12 are joined by the rubber cover 12c via a slip-preventive surface that prevents hair from being pinched. The hair is pinched by the magnetic attraction force F and the friction coefficient μ of the slip-preventive surface. In contrast to this, in the second embodiment, the back body 12 has a magnetic joint 12a surrounded by a yoke body 12b, and the joint surface of the magnetic joint 12a is joined via an uneven slip prevention surface, so that the pair of magnetic joints 11 and 12 are sandwiched against the body hair by the magnetic attraction force F and the friction coefficient μ of the slip prevention surface.

[0022] The pair of magnetic couplers 11, 12 of the present invention can be broadly divided into those forming the magnetic circuit MC1 shown in Fig. 3(a) and those forming the magnetic circuit MC2 shown in Fig. 3(b). The flow of magnetic field lines in the magnetic circuit MC1(a) of the first embodiment and the magnetic circuit MC2(b) of the second embodiment is shown in Fig. 3. In the first embodiment (a), the magnetic field lines from the magnetic coupler 11a reach the top end of the yoke body 11c to the bottom and merge with the magnetic field lines from the magnetic coupler 12a, thereby achieving efficient magnetic coupling. In the second embodiment (b), the magnetic field lines from the magnetic coupler 11a reach the top end of the yoke body 11c to the bottom, while the magnetic field lines from the magnetic coupler 12a pass through the yoke body 12b and merge at the bottom of the yoke body 11c, thereby achieving more efficient magnetic coupling.

[0023] 4 is a functional diagram of the pet hair ring of the present invention. In the first and second embodiments, the front body 11 is formed by housing the ornamental part 11a and the magnetic connection body 11b within a cylindrical yoke body 11c, while the rear body 12 has the magnetic connection body 12a surrounded by a rubber cover 12c, so that the pair of magnetic connection bodies 11 and 12 are joined by the rubber cover 12c via the slip prevention surface when clamping the hair, and are clamped by the magnetic attraction force F and the friction coefficient μ of the slip prevention surface. In contrast, in the second embodiment, the rear body 12 has the magnetic connection body 12a surrounded by a yoke body 12b, and the joining surface of the magnetic connection body 12a is joined via an uneven slip prevention surface, so that the pair of magnetic connection bodies 11 and 12 are clamped by the magnetic attraction force F and the friction coefficient μ of the slip prevention surface. The back body 12 is surrounded by a rubber cover 12c, and a detachable annular part 12e is formed at the rear end or the peripheral part in the vicinity thereof, so that the joined state can be easily released by pinching the back body 12 with fingers and bending the axis passing through the pair of magnetic joining bodies 11, 12.

[0024] Figure 5 is a plan view showing various forms of slip-drop prevention surfaces at the joining end faces (a), (b), (c), (d), and (e). For flat joining faces, a rubber sheet surface is provided to form a slip-prevention surface for body hair. When no rubber sheet joining surface is provided, a complementary uneven surface is provided. In the case of Figure 9B, the slip prevention function can be achieved by fitting.

[0025] 6A and 6B are cross-sectional views showing various configurations of the rear body of a pair of magnetically coupled bodies, in which (a) shows a case in which the magnetically coupled body 12a is surrounded by a cylindrical yoke body 12b, (b) shows a case in which the magnetically coupled body 12b is surrounded by a rubber cover 12c, and (c) shows a case in which the magnetically coupled body 12a is surrounded by a cylindrical yoke body 12b and its outer periphery is surrounded by a rubber cover 12c. In (a), the magnetically coupled body is surrounded by the yoke body 11c of the front body and the yoke body 12b of the rear body, forming the magnetic circuit MC2 of Fig. 3B. In (b), the yoke body 11c of the front body is surrounded by the pair of magnetically coupled bodies 11b and 12b, forming the magnetic circuit MC1 of Fig. 3A. In (c), not only is the magnetic circuit MC2 formed, but the magnetically coupled body is also covered by a rubber cover 12c, making it easy to separate the pair of magnetically coupled bodies.

[0026] FIG. 7A is a cross-sectional view illustrating the function of a first embodiment of the present invention, and FIG. 7B is a cross-sectional view illustrating the function of a second embodiment of the present invention. As shown in FIGS. 7A and 7B, the pair of magnetically coupled bodies 11 and 12 can be separated and separated by applying a force in a direction that bends the back-side magnetically coupled body 12 with respect to an axis L that passes through the center of both bodies.

[0027] Specifically, the mating surfaces of one or both of the pair of magnetic joints 11, 12 preferably have a slip prevention surface with a friction coefficient μ to reinforce the adhesive force. As shown in Figure 5(a), the mating surfaces may be provided with a rubber viscoelastic layer made of silicone resin or synthetic resin, and these may be abutted against each other. Alternatively, as shown in Figures 5(b) to 5(e), 1) the mating surfaces may be metal concave-convex complementary mating surfaces, or parallel concave grooves and ridges, or 2) concentric grooves and ridges, or concentric grooves and ridges, may be a complementary concave-convex portion. Also, 3) the concave-convex portions may be interlocked by wavy portions or zigzag portions, ensuring a constant friction coefficient. Alternatively, 4) one concave portion and one convex portion may be interlocked with loose fit, or multiple circular protrusions may be interlocked to form a slip prevention portion.

[0028] The magnet must have a small interface, e.g., a diameter of 5 to 10 mm, to achieve a magnetic flux density of 3,000 gauss, preferably 4,000 gauss or greater. Therefore, rare earth magnets are recommended. Neodymium magnets are particularly useful, and they can be used with the yoke body 11c of the front body 11 or the cylindrical yoke bodies 11c and 11b of the front body 11 and the back body 12 to form magnetic circuits MC1 and MC2 that ensure an appropriate flow of magnetic lines of force in both magnetically coupled bodies. When forming magnetic circuit MC2, samarium-cobalt magnets can be used instead of neodymium quartz to achieve sufficient magnetic attraction. 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 magnetically coupled bodies 11 and 12 may be magnetic bodies, or one may be a magnetic body and the other a magnetic metal body.

[0029] The magnet is preferably in the form of a columnar rod, since it can be bent and separated from the axis of the pair of magnetic joints 11, 12. Since neodymium magnets rust easily, they are surrounded by a yoke body or silicone rubber, etc. In the case of a yoke body, it is preferable to plate it with a precious metal to give it a decorative appearance.

[0030] When the magnetic body is surrounded by silicone rubber 12c, it is preferable to form it into a cylindrical shape as shown in Figures 8(a) and 8(b), and as shown in Figure 8(c), to have a large opening at the joining surface 12f with a groove 12g around it to accommodate the magnetic body 12a, and to have an annular flange 12d at or near the rear end. The hole 12R at the rear end is a punch hole used during molding.

[0031] 9A and 9B are perspective views showing a configuration for reinforcing the first centering function in a magnetically joined device. In addition to the magnetically joined device configuration, in FIG. 9A, a pair of front and back joined bodies 11 and 12 have a first engaging portion consisting of a short convex engaging portion 11d and a shallow concave engaging portion 12f, which allows the tubular bodies 11c and 12b of the front and back joined bodies 11 and 12 to fit together by axial movement and to be uncoupled by folding the pair of joined bodies 11 and 12. Note that in the front joined body 11, 11a denotes the jewelry body, 11b denotes the magnetic joined body, and 11c denotes the tubular body, while in the back joined body 12, 12a denotes the magnetic joined body, and 12b denotes the tubular body. In FIG. 9B, the centering function employs a modified example shown in FIG. 10. That is, the pair of front and back joining bodies 111, 112 have a shallow annular engaging portion on one side, and are fitted together by the axial movement of the cylindrical bodies 11c and 12b. In Fig. 9B, a shallow annular engaging portion 12g is formed at the opening of the cylindrical body 12b, and the bottom portion 11d of the cylindrical body 11c is fitted into the shallow annular engaging portion 12g to reinforce centering.

[0032] Figure 10 is a perspective view of a structure and joining method that does not have a magnetic joining structure and is only a physical joining type, where (a) shows the state before the front joining body is joined to the back joining body in a fitting manner, (b) shows the joined state, (c) shows the locked state, and (d) shows the state when the locking function is activated and the pet hair is clamped. That is, the pet hair ring is an accessory that is attached to a pet by clamping its hair, and comprises a joint 110 consisting of a pair of front and back joints, front and back, that clamp the pet's hair and are joined together with their tips butted against each other, and a decorative part 120 such as jewelry that is attached to front joint 111 and is visible from the outside when attached, and the joint 110 consisting of the pair of joints has the following functions necessary for attachment to a pet: 1) a first centering function that clamps the hair when gripping it and aligns the center of the pair of joints, 2) a second locking function that locks the joined state of the pair of joints, and 3) a third anti-fall function that prevents the pair of joints from falling out of the pet's hair, and in performing these functions with a physically joined configuration, A) front joint 111 of the joint is configured to contain and store at least a jewel or other jewelry body 111a within a cylindrical body 111c, B) The front-side joined body 111 or the rear-side joined body 112 on the opposite side thereof is configured so that the cylindrical bodies 111c and 112b contain an elastic body that biases the cylindrical bodies 111c and 112b in the axial direction thereof, and is formed into a rod-like shape having a length that can be held with fingertips; C) A pair of front and back joined bodies 111,D) the cylindrical bodies 111c and 112b of the pair of joined bodies are provided with first engaging portions 111d and 112g that engage with each other as the cylindrical bodies 111c and 112b move in the axial direction, and are configured to engage with each other via the first engaging portions, thereby fulfilling the first centering function; D) the cylindrical bodies 111c and 112b of the pair of joined bodies are provided with protrusions 111e and notches 112f that form second engaging portions that engage with each other as the cylindrical bodies 111c and 112b move relative to each other around the axis L to prevent movement in the axial direction, thereby fulfilling a second locking function that prevents the pair of cylindrical bodies 111c and 112b from separating in the axial direction; E) The pair of cylindrical bodies 111c, 112b engage with each other by relative rotation around the axis, and comprise second engagement portions 111e, 112f that increase or decrease the depth of the joint in the axial direction (although the cut angle is shown as 30 degrees in the figure, a shallow inclination of 5 to 30 degrees is desirable due to the unevenness into which 111e fits), and are biased in the axial direction by the elastic body G, providing a third anti-fall function that prevents the pet's hair from falling out at the pair of joints; F) The pair of joints 111, 112 are unlocked by rotating them relative to the axis L passing through the center of both bodies, thereby separating the joint and forming a detachable pet hair ring. In the specific example of Figure 10, as shown in Figure 10(d), the pair of joints 111, 112 engage with each other to sandwich the hair, and the biasing force of the elastic body G presses the hair in the axial direction to hold it in place.

[0033] Figure 11 is a perspective view of a system that includes both physical and magnetic joining methods. It has the same physical joining configuration as Figure 10, but uses a shallower fitting method than Figure 10, and reinforces the two by physical fitting and magnetic joining. (a) shows the state before the front joining body is joined to the back joining body by fitting, (b) shows the fitted state, and (c) shows the locked state. The same numbers are used for the same components as Figure 10. That is, in the structure and joining type that combines physical joining and magnetic joining, there is provided a pet hair ring, which is an accessory that is attached to a pet by clamping its hair, and which comprises a joining part 110 consisting of a pair of front and back joining parts, front joining part 111 and back joining part 112, which are joined together with their tips butted against each other and hold the pet's hair, and a decorative part 120 such as jewelry that is attached to front joining part 111 and is visible from the outside when attached.

In performing these functions with a physical joining configuration and a magnetic joining configuration, A) The front-side joined body 111 of the joined part is configured by stacking a jewelry body 111a such as a gemstone and a magnetic joined body 111b, and containing and storing them in a cylindrical body 110c, while B) the back-side joined body 112 on the opposite side of the front-side joined body is configured by containing a magnetic joined body 112a in a cylindrical body 112b and forming it into a rod-like shape of a length that can be held with the fingertips, and C) the pair of front and back joined bodies 111, 112 have first engaging portions 111d, 112g that are fitted together by axial movement of the cylindrical body 111c and the cylindrical body 112b, and are configured to be fitted together via the first engaging portions, and the pair of joined bodies 111,D) the cylindrical bodies 111c, 112b of the pair of coupling bodies have second engaging portions 111e, 112f (when biased in the axial direction by magnetic coupling force, the notches may be horizontal) that prevent axial movement by relative rotation about the axis, and a second locking function that prevents axial separation is achieved by the magnetic coupling of the pair of magnetic coupling bodies and engagement of the pair of cylindrical bodies 111c, 112b; and E) the pair of cylindrical bodies 111c, 112b are biased in the axial direction by the magnetic coupling force of the pair of magnetic coupling bodies 111, 112 as well as the relative movement about the axis, and a third anti-fall function that prevents pet hair from falling out at the pair of coupling portions. F) The pair of connecting members 11 and 12 are unlocked by rotating them relative to an axis L passing through the center of both members, thereby providing a pet hair ring that can be separated and removed.

[0034] The present invention provides pet earrings as a pet accessory, and also provides a new way of using pet accessories, called double wearing, in which the pet owner wears the same pet accessory as their pet (see Figure 1(b)).
