Description

  The present invention relates to a tool for wearing an earring such as a piercing. In this application, the term “earrings” simply means non-piercing earrings unless otherwise specified.

  There are earrings and earrings as ornaments attached to the ear. Piercings must have holes in the earlobe and are hated by those who are afraid of drilling. On the other hand, a general earring consists of a leaf spring and a screw part, etc., and the spring pressure is adjusted by turning the screw according to the thickness of the earlobe, because the elastic force of the leaf spring keeps pressing the earlobe. It causes pain with the passage of time. If you loosen the screw to avoid pain, the earring will easily fall out of your ear. In addition, fasteners are large and inferior in fashion compared to earrings.

Therefore, smart earrings that look small like fasteners and look like pierced earrings are preferred. For example, an earring in which a small loop is formed by winding an elastic wire in a recess of an elastic wire formed by attaching a decorative body to both ends and forming a U shape (U.S. Pat. Hinging one end of a pair of semicircular ring pieces via a washer and caulking the connecting part creates a clamping force between the other ends of the ring pieces. An earring (Patent Document 3) or the like has been proposed. Also, a coil spring is incorporated inside and a circularly bent pipe and a pin attached to the end of the coil spring and protruding from one end of the pipe are provided, and the restoring force of the coil spring causes an earlobe with the tip of the pin and the other end of the pipe Non-patent documents 1 have been put on the market to be inserted.
Then, the present applicant also proposed a piercing-like earring superior to the above conventional earring, and also proposed a tool for wearing the earring (Patent Document 4).

  The subject of the present invention is disclosed in US Pat. No. 5,677,959 in order to easily wear an earring that looks like a piercing and can be fixed to the earlobe by its own elastic restoring force and does not cause pain. To provide a tool that is further improved.

The earrings targeted by the attachment of this invention are usually
A connecting portion made of an elastic wire and bent in a U-shape so as to maintain a predetermined distance between both ends,
It comprises a pair of ear rests which are made of the same or different material as the above-mentioned material, are wider than the connection portion, and are provided on both ends of the connection portion so that the main surfaces face each other.

  According to the earring, since the ear rest holds the earlobe by the elastic force of the connecting part during wearing and the connecting part is made of a wire, it looks like a piercing. In addition, since the distance between both ends of the connecting portion is maintained, the distance between the two ear pads is also maintained, and an excessive pressure is not applied to the earlobe. Moreover, since the ear pad portion is wider than the connection portion, the pressure applied to the earlobe from the connection portion is dispersed. For this reason, you will not feel pain even if you wear it for a long time. The material of the ear pad may be different from or the same as that of the connecting part. When different, they may be fixed to the joint by adhesion or welding through an adhesive. When identical, they are provided integrally with the connecting part.

The mounting tool of the present invention for mounting the earring is:
The front end edge is provided with a pair of levers that are openably and closably connected with each other at a fulcrum shaft. And these levers have an introduction part which can introduce an earlobe at or near the front end edge, and have a pair of projections between the front end edge or it and the fulcrum shaft at a different position from the introduction part It is characterized in that it can be inserted into the U-shaped connection of the earring, and the outer surface spacing of the projections is smaller than the inner surface spacing of the introducing portion when the front end edge is in the open state.

  The front end edge of the lever may be opened by the elastic restoring force of the lever itself or may be opened by an external force. The introduction portion and the projection open and close with the opening and closing of the front end edge. The fulcrum shaft may be part of the lever or may be a separate entity from the lever. The lever may be made of metal, wood or plastic, but at least the projection and its periphery are preferably made of metal in order to ensure the necessary strength.

  When using this mounting tool, the front edge is closed or half-opened, the protrusion is inserted into the U-shaped connection of the earring, an external force is applied to fully open the front edge. Then, the protrusion and the introducing portion are fully opened together with the front end edge, the outer surface of the protrusion is pushed against the elastic restoring force of the connecting portion near the both ends of the connecting portion, and the earring is held via the protrusion. Then, an earlobe is inserted between the ear pads of the earring via the introduction section. Since the inner surface distance of the lead-in portion is larger than the outer surface distance of the projections, it is easy to insert the earlobe. In this state, the external force is weakened and the mounting tool is pulled out, whereby the earring is fixed to the earlobe by the elastic restoring force of the connecting portion. Since the earring can be held with one hand via the mounting tool, the earlobe can be fixed with the free hand, and the earlobe can be pulled as thin as necessary while the positional relationship with the earrest portion of the earring is checked by touch. You can easily wear the earring. The part behind the position of the projection on the lever may be thicker or wider than the front part. It is because it becomes easy to hold a mounting tool by this composition.

  It is preferable that the front end edge also serves as the introduction portion, and the projections extend parallel to the fulcrum axis at mutually opposing positions between the front end edge and the fulcrum axis. Since the projection holding the earring is located between the front end edge of the lever and the fulcrum shaft, the distance between the opposing projections is smaller even when the front end edge (introduction part) is fully open. For this reason, while the earlobe can be easily guided between the ear pads via the widely open front end edge (introduction portion), the distance between the ear pads is excessive beyond the elastic range of the connecting portion. You can also prevent it from spreading. Therefore, the distance between the ear pads can be easily expanded by the action of the eyelid without worrying about the plastic deformation of the connecting portion.

  The projection preferably has a straight portion and a tapered portion continuing on the side far from the introduction portion of the straight portion, and the outer surface of the straight portion is provided flush with the outer main surface of the lever, and is tapered The outer surface of the part goes inward as it goes away from the straight part. According to this configuration, since a wide width is secured between the straight portion and the tapered portion, even a user with weak vision such as an elderly person can easily recognize the protrusion and secures the necessary strength for the protrusion. You can also In addition, although the projections are fully open when the mounting tool holds the earring, the tapered portions follow the connecting portions or form a relief between the connecting portions, so that the width of the projections is relatively wide. There is no excessive spread of the gap between the abutments.

  It is particularly preferable that the projections have a pentagonal shape in a cross section perpendicular to the projecting direction, since they have no sharp parts and are high in safety and strength.

  One preferred general configuration A of the mounting device is that the pair of levers have a front and a rear, respectively, and the front and the rear are opened so that the front end opens or closes when the rear end closes or opens. It is connected via the said fulcrum shaft between. According to this configuration A, the earring can be attached while holding the closed rear. Also, the turning angle of the lever is limited by the fact that the rear end edge of the first lever and the rear end edge of the second lever abut on each other. Thus, the maximum spacing of the outer surface of the projections is always constant. In this configuration, if there is a spring that biases the rear end of the pair of levers in the opening direction, the force of the spring closes the front end without applying an external force. It may be easy to insert the projections and to pull out the fitting from the earlobe.

  Moreover, according to the configuration A, the fulcrum shaft serves as a stopper, and it is possible to prevent excessive insertion of the earring. In this configuration, the distance between the front end edge and the front surface of the projection and the distance between the front surface of the projection and the fulcrum shaft are usually 8 to 12 mm. If the former is less than 8 mm, it will be difficult to perform the guiding function of the front end edge, and if it exceeds 12 mm, the front end edge may hit the ear cartilage. If the latter is less than 8 mm, the earlobe may not be sufficiently inserted between the ear pads, and if it exceeds 12 mm, it may be too large.

  Each lever of the configuration A usually has a bearing portion at both end edges in the fulcrum axial direction. And the bearing part located in the edge of the side which has the said protrusion among those bearing parts preferably does not protrude in the fulcrum axial direction rather than the starting point of a protrusion. Thus, when the earring is held by the mounting tool, the connection portion of the earring and the bearing portion do not interfere with each other, so that the possibility of detachment or damage of the earring from the mounting tool is reduced. Furthermore, if the portion of the end edge of the lever adjacent to the bearing portion is recessed in the fulcrum direction from the start point of the protrusion, the possibility of the earring falling off or being damaged is further reduced.

  In another preferable overall configuration B of the mounting tool, the pair of levers is V-shaped, the upper end of the V is the front end edge, the lower end is the fulcrum shaft, and the front end is opened and closed by elastic deformation of the V And operate on the same principle as known tweezers. When the mounting tool of this configuration B is used, an external force in the direction of narrowing the V-shaped portion is applied to close the front end edge or the semi-closed state, insert the projection into the connection portion of the earring, and then release the external force. Do. As a result, the outer surface of the projection is pressed against the elastic restoring force of the connecting portion in the vicinity of both ends of the connecting portion, and the earring is held via the projection. Even if the mounting tool is freed, the holding state of the earring by the mounting tool is maintained. In this configuration B, a stopper for limiting the degree of opening of the V is provided. This reliably prevents the connection part from opening too much. The stopper may be a chain or a string attached across the opposing inner surfaces of the pair of levers.

  In still another preferred overall configuration C of the mounting tool, the pair of levers extend from the upper end of the V-shaped portion and toward the other from the upper end of the V-shaped portion, intersect and continue extending away from the lower end of the V-shaped portion An L-shaped pair portion, the tip of the L-shaped pair portion being the front end edge, the lower end of the V shape being the fulcrum shaft, and the front end edge being opened and closed by elastic deformation of the V shape It operates on the same principle. When the mounting tool of this configuration C is used, an external force in a direction to narrow the V-shaped portion is applied to open the front end edge in a state where the protrusion is inserted into the connection portion of the earring. Thus, the projection is pushed by the connecting portion, and the earring is held via the projection. When the V-shape is closed, the front end edge is fully opened, and the front end edge is not opened further, so that the connecting portion is prevented from being opened too much.

  In any of the configurations including the configurations A to C, the maximum distance between the outer surfaces of the protrusions when the front end edge is open is usually 10 mm or less, preferably 8 mm or less. Although depending on the total length, elastic modulus and outer diameter of the elastic wire constituting the connecting portion, and the location where the outer surface of the projection is in pressure contact, the interval between the ear pads is always set by setting the maximum distance of the front outer surface to 8 mm or less It will expand within the elastic range of the connection part, and plastic deformation of the connection part can be reliably prevented.

  As described above, according to the earring mounting tool of the present invention, the connecting portion is too open to plastically deform the earring, and the earring can be easily attached to the earlobe.

-Embodiment 1-
The earring 1 of this embodiment, as shown in FIG. 1, has a U-shaped connecting portion 2 in a front view, disc-like ear pads 3 and 3 fixed to both ends of the connecting portion, and ornaments 4 and 4, respectively. Equipped with
The connecting portion 2 is formed by bending a high-strength piano wire having a diameter of 0.5 mm into a U-shape having a distance between both ends of the thickness of an earlobe, for example, 5 mm to 6 mm. The distance between the ends of the U and the bottom may be, for example, about 10 mm, so that the bottom of the U does not push up the earlobe and both ends of the U strike against the thin portion of the earlobe.

  The ear pads 3, 3 are each made of a metal, such as brass, iron, stainless steel or the like, having a thickness of 0.5 mm, and substantially disk-shaped substrates 3a, 3a and pads 3b, 3b. The substrates 3a, 3a have cuts (not shown) having a width substantially corresponding to the diameter of the wire in the radial direction from the center thereof. Then, the connecting portion and the substrates 3a and 3a are welded in a state in which one end of the connecting portion 2 is fitted to the cut of the substrate 3a and the other end is fitted to the cut of the other substrate 3a.

  The pads 3b, 3b have a disk shape made of urethane rubber, and are adhered to the inner surfaces of the substrates 3a, 3a, respectively. The diameter of the substrate 3a and the pad 3b is usually 3 to 7 mm, preferably about 4 mm, and the diameter of the substrate 3a and that of the pad 3b may be the same or different. The decoration 4 is attached to the outer surface of the substrate 3a. The distance between the pads 3 b and 3 b is usually 1.5 to 2.5 mm, depending on the thickness of the earlobe of the person wearing the earring 1.

  When wearing the earring 1, the space between the ear pads 3 and 3 of the earring 1 is expanded with the mounting tool 5 described later, and the earlobe is inserted between the ear pads 3 and 3, and the ear pads 3 and 3 are interposed. The earring 1 is fixed to the ear by sandwiching the earlobe with the elastic restoring force of the connector 2. In order to be able to cope with various types of wearers, earrings 1 having different sizes of the connecting portion 2 and the thickness of the pad 3b may be prepared.

  Since the pads 3b, 3b softly hit the earlobe, the earring 1 does not damage the earlobe when the earlobe is inserted. In addition, even if an unexpected impact is applied to the earring 1 during mounting, the positional displacement of the earring 1 is prevented by the frictional force between the pads 3b, 3b and the earlobe, and the pads 3b, 3b absorb part of the impact. Because I do, I rarely get injured. Since the earring 1 has no screw, it looks like an earring during wearing.

  The mounting tool 5 includes first and second pairs of levers 6 and 7 made of a stainless steel plate or a rustproofed metal plate as shown in FIG. 2, a rotary shaft 8, and a torsion spring (not shown). . And as shown in FIGS. 3-6, bearing parts 6a, 6b, 7a, 7b which support the rotating shaft 8, and a pair of protrusion 9, 10 are formed in the lever 6,7. The levers 6 and 7 are symmetrical to each other by being surrounded by two long parallel sides except the bearing portions 6a, 6b, 7a and 7b and the pair of protrusions 9 and 10 and short semicircular sides connecting the two sides. And each have a front and a back with the rotary shaft 8 as a boundary.

  The first lever 6 and the second lever 7 are connected via the rotation shaft 8 between the front and the rear so that the front end opens (closes) when the rear end closes (opens). There is. That is, the front and the rear open and close in mutually opposite directions according to the principle of a wedge having the rotation axis as a fulcrum, the front as an action point, and the rear as a power point. The torsion spring is wound around the rotating shaft 8 so that an elastic restoring force acts in the direction in which the rear end edges of the levers 6 and 7 open. The length from the rotating shaft 8 to the rear end edge is 1.5 times the length from the rotating shaft 8 to the front end edge. In the illustrated example, the total length of the levers 6, 7 is 50 mm, the distance from the rotation shaft 8 to the front surface of the projection 9 (10) is 10 mm, and the distance from the front surface of the projection 9 (10) to the front edge of the lever 6 (7) Is 10 mm, the height of the levers 6, 7 or the length in the direction of the rotating shaft 8 is 10 mm, and the wall thickness is 1.0 mm.

  The bearing portions 6a and 7a extend in a direction perpendicular to the main surfaces of the levers 6 and 7 from the first long sides of the levers 6 and 7, respectively. However, the bearing portion 6a is recessed in the direction of the rotation shaft 8 by the thickness of the bearing portion 7a. The bearing portions 6 b and 7 b extend in the direction orthogonal to the main surface from the second long sides of the levers 6 and 7. However, the bearing portion 7 b protrudes in the direction of the rotation shaft 8 by a plate thickness more than the bearing portion 6 b.

  The protrusions 9 and 10 have straight portions 9a and 10a positioned between the tip end of the levers 6 and 7 and the rotary shaft 8 and tapered portions 9b and 10b connected to the rear of the straight portions. It extends parallel to the rotation axis 8 from the first long side. The outer surfaces of the straight portions 9a and 10a are on the outer main surfaces of the levers 6 and 7, and the outer surfaces of the tapered portions 9b and 10b are directed inward as they are farther from the straight portions 9a and 10a. Accordingly, in the cross section orthogonal to the rotation axis 8, the projections 9 and 10 form pentagons in which opposing surfaces are parallel except that the outer surfaces of the tapered portions 9 b and 10 b are inclined. The distance between the outer surfaces of the straight portions 9a and 10a is 7 to 8 mm when the front end edges of the levers 6 and 7 are open.

  When the mounting tool 5 is used, the front end edge is half-opened, the protrusions 9 and 10 are inserted inside the connection portion 2, and an external force against the elastic restoring force of the torsion spring is applied to close the rear end edge. Then, as shown in FIG. 7, the front end edge is completely opened and the projections 9 and 10 are pushed by the connecting portion 2, and the earring 1 is held by the mounting tool 5. Since the distance between the outer surfaces of the straight portions 9a and 10a is much larger than the distance between the pads 3b and 3b, the protrusions 9 and 10 are erroneously inserted between the pads 3b and 3b to plastically deform the connecting portion 2 There is no risk of accidents.

  The protrusions 9 and 10 have a sufficiently wide width by the straight portions 9a and 10a and the tapered portions 9b and 10b, so even a user with poor vision such as an elderly person can easily recognize the connection portion 2 It can be inserted inside. In addition, since the distance between the projections 9 and 10 is maximized in the state in which the rear end edges are aligned, the gap between the ear pads 3 and 3 does not open too much to return to the original distance. In addition, since the outer surfaces of the tapered portions 9b and 10b are directed inward as they move away from the straight portions 9a and 10a, the degree of opening of the connecting portion 2 is small enough. The reason will be described in detail later.

  Then, as shown in the insertion direction of the earlobe by arrows in FIG. 7 and the procedure in FIGS. 8 to 12, respectively, the mounting tool 5 is held by one hand and the position of the mounting tool 5 and the earlobe by the other hand While confirming the relationship (FIG. 9), insert the earlobe between the protuberances 9, 10 through the front edge (FIG. 10). Because of the presence of the rotation axis 8, the earlobe does not get too much, so that the front edge does not hit the cartilage. In that state, the external force applied to the rear end edge is released. Then, the rear end edge is opened by the elastic restoring force of the torsion spring and the distance between the projections 9 and 10 is narrowed, and the earlobe is pinched by the ear rests 3 and 3 by the elastic restoring force of the connecting portion 2 (FIG. 11). Thereafter, the earring 1 is fixed to the earlobe by slowly removing the mounting tool 5 backward while lightly pressing the ornaments 4 and 4 from both sides of the earlobe with fingers (FIG. 12).

  Since the bearing portions 6a, 7a do not project from the start points of the protrusions 9, 10 or are recessed in the direction of the rotation shaft 8, when the earring 1 is held by the mounting tool 5, the connecting portion 2 and the bearing portion 6a, There is no interference with 7a. Therefore, it is possible to prevent the falling off and damage of the earring 1 from the mounting tool 5.

  According to the mounting tool 5, since the protrusions 9 and 10 are located between the front end edges of the levers 6 and 7 and the rotary shaft 8, the distance between the opposing protrusions is small even when the front end edges are fully open. For this reason, as described above, the earlobe can be easily guided between the earrests 3 and 3 via the wide open front end edge, but the ear rests beyond the elastic range of the connecting portion 2 It is possible to prevent the interval between 3 and 3 from spreading excessively. Therefore, the earring does not plastically deform and fail.

  Next, the reason why it is optimal that the cross sections of the projections 9 and 10 have a pentagonal shape as described above will be described in detail. The projections 9 and 10 are shown in FIG. 13 because in the cross section orthogonal to the rotation axis 8, the opposing surfaces are parallel pentagonal except that the outer surfaces of the tapered portions 9b and 10b are inclined. Even if the degree of opening of the connecting part 2 is small by the amount inward along the slope, the spacing of the ear pads 3, 3 and the spacing of the projections 9, 10 necessary for putting in the earlobe it can. In addition, the strength required for the projections 9 and 10 can be secured.

  On the other hand, when the projections 9 and 10 have a trapezoidal shape in cross section as shown in FIG. 14, even if the degree of opening of the connecting portion 2 is small, the distance between the ear pads 3 and 3 necessary for putting in the earlobe Although the distance between the projections 9 and 10 can be secured, excessive nerves must be used for handling so that the user is not injured by the sharp ridges indicated by the arrows. In addition, the projections 9 and 10 tend to chip at sharp edges.

  However, if the cross section of the projections 9 and 10 is a simple rectangle, either of the wall thickness as shown in FIG. 15 or the wide width as shown in FIG. In the opening condition, the spacing between the ear pads 3 and 3 and the spacing between the projections 9 and 10 necessary for putting in the earlobe can not be secured.

-Embodiment 2-
In this embodiment, as shown in FIG. 17, both sides 6c, 6d, 7c, and 7d of the bearing portions 6a and 7a are recessed 1.5 to 2.5 mm in the main surface direction of the levers 6, 7, respectively. Accordingly, the earring 1 is not only hit by the bearing portions 6a, 7a but also by both sides thereof from falling off from the mounting tool 5 or being damaged.

-Embodiment 3-
The mounting tool 15 of this embodiment is, as shown in FIGS. 18 and 19, made of metal straddling the opposing inner surfaces of a pair of V-shaped levers 16 and 17 and the levers 16 and 17. And a stopper 23 consisting of a chain. Then, at the upper end of the V-shape, the protrusions 19 and 20 project in the substantially extension direction of the V-shape, and the introducing portions 21 and 22 are formed near the protrusions 19 and 20. The introduction portions 21 and 22 extend in a direction substantially orthogonal to the projecting direction of the protrusions 19 and 20 but in a direction in which they are slightly expanded. The protrusions 19 and 20 have a straight portion as in the first embodiment and a tapered portion connected to the straight portion. The lower end of the V is used as a fulcrum shaft, and the upper end of the V is opened and closed by elastic deformation of the levers 16 and 17, and the degree of opening is limited by the stopper 23. Therefore, the mounting tool 15 operates based on the same principle as known tweezers except for the protrusions 19 and 20, the introducing parts 21 and 22, and the stopper 23.

  When the mounting tool 15 is used, the external force is applied to narrow the V-shaped portion, and after the protrusions 19 and 20 are inserted into the connecting portion 2 of the earring 1, the external force is released. Thereby, the projections 19 and 20 are pushed by the connecting portion 2 against the elastic restoring force of the V-shaped portion, and the earring 1 is held via the projections 19 and 20. Even when the mounting tool 15 is released, the holding state of the earring 1 by the mounting tool 15 is maintained. Since the maximum distance between the projections 19 and 20 is determined by the length of the stopper 23, the connecting portion 2 does not extend excessively.

Next, an earlobe is inserted between the projections 19 and 20 through the introduction portions 21 and 22. In this state, when an external force is applied in a direction to narrow the V-shaped portion, the earlobe is pinched by the ear rests 3 and 3 by the elastic restoring force of the connecting portion 2. Thereafter, the earring 1 is fixed to the earlobe by removing the mounting tool 15. As in the first embodiment, the connecting portion 2 is not plastically deformed, and during operation, the mounting tool 15 can be held by one hand and the earlobe can be held by the empty hand.
In the attachment tool 15 similar to the tweezers, the front end edges of the levers 16 and 17 are the introduction portion as in the first embodiment, and instead of the protrusions 19 and 20, between the front end edge and the fulcrum shaft as in the first embodiment. The projection may be provided with a projection extending parallel to the fulcrum shaft.

-Embodiment 4-
The mounting tool 25 of this embodiment, as shown in FIGS. 20 and 21, extends in a direction approaching each other from the V-shaped portion and the upper end of the V, intersects and continues extending in the direction away from the lower end of the V-shaped portion. A pair of levers 26 and 27 each having a character pair portion. Then, at the upper end of the L-shape, the protrusions 29 and 30 project in a substantially extension direction of the L-shape, and the introducing portions 31 and 32 are formed near the protrusions 29 and 30, respectively. The introducing portions 31 and 32 extend in a direction substantially orthogonal to the projecting direction of the protrusions 29 and 30 but slightly expanding each other. As in the first embodiment, the protrusions 29 and 30 have a straight portion and a tapered portion connected to the straight portion. Then, the lower end of the V-shape is used as a fulcrum shaft, and the tip of the L-shaped pair part is opened and closed by elastic deformation of the V-shape. Thus, the attachment 25 operates on the same principle as the known reverse actuating tweezers except for the protrusions 29, 30 and the introducers 31, 32.

  When the mounting tool 25 is used, with the protrusions 29 and 30 inserted in the connection portion 2 of the earring 1, an external force in a direction to narrow the V-shaped portion is applied to open the tip of the L-shaped pair. Thereby, the projections 29 and 30 are pushed by the connecting portion 2 and the earring 1 is held via the projections 31 and 32.

Then, an earlobe is inserted between the projections 29 and 30 through the introduction portions 31 and 32. When the external force is released in this state, the earlobe is pinched by the ear rests 3 and 3 by the elastic restoring force of the connecting portion 2. Thereafter, the earring 1 is fixed to the earlobe by removing the attachment 25. As in the first embodiment, the connecting portion 2 is not plastically deformed, and during operation, the mounting tool 25 can be held by one hand and the earlobe can be held by the empty hand.
In the attachment tool 25 similar to the tweezers, the front end edges of the levers 26 and 27 are used as the introduction portion, and the protrusions 29 and 30 are replaced with protrusions extending parallel to the fulcrum shaft at an intermediate position of L It may be provided.
