Description

[Technical field]

[0001] The present invention relates to pivoting (clip-on) earrings that are worn by clamping the earlobe. [Background technology]

[0002] Many documents have presented earrings in which a member having a clamping portion for clamping the earlobe and a member facing the clamping portion for clamping the earlobe are connected (axially attached) by a single axis, allowing the respective components to rotate relative to one another.

[0003] Among the many documents, Patent Document 1 is cited as an easy-to-understand example. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2006-267 A Summary of the Invention [Problem to be solved by the invention]

[0005] In Patent Document 1, arc-shaped members 1 and 2 are rotatably connected via a connecting shaft 5, and a bifurcated mounting leg is formed at the base end of arc-shaped member 1.

[0006] However, when the arc-shaped members 1 and 2 are rotated to put on or take off the earrings, the load of the rotation cannot be distributed, which may cause problems when putting on or taking off the earrings.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide earrings that reduce the burden placed on the rotation of the clamping member (arc-shaped member) that clamps the earlobe, making them easier to put on and take off. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems, the earring of the present invention comprises a first member 110 having a first clamping portion 111 at its tip for clamping the earlobe, a second member 120 having a second clamping portion 121 at its tip for clamping the earlobe opposite the first clamping portion 111, and a third member 130 having a third clamping portion 131 at its tip for clamping the earlobe opposite the first clamping portion 111, and the base ends of the first member 110, the second member 120 and the third member 130 are rotatably connected by a connecting shaft. Effect of the Invention

[0009] In the present invention, the second member 120 and the third member 130 are separate and can be rotated individually, compared to the conventional configuration in which the second member 120 and the third member 130 are integrated, so that the force required to put on and take off the earrings can be reduced by rotating them individually. Therefore, it is possible to easily put on and take off the earrings. [Brief description of the drawings]

[0011] In the present invention, "upper, lower, left, right, front, back" (in the case of perspective views) and "upper, lower, left, right" (in the case of two-dimensional views) are indicated with arrows in the drawings. Furthermore, the "inner side" of each member in each embodiment of the present invention refers to the side closer to the center of the earring, and conversely, the "outer side" refers to the side farther from the center of the earring.

[0012] In the description of each embodiment and its modified examples, the same reference numerals will be used to refer to the same components unless there is any misunderstanding. In addition, when the components have the same configuration or shape, the description of the duplicated parts will be omitted as appropriate, and the description will focus on the differences.

[0013] In the present invention, when the first member 110, the second member 120, and the third member 130 are all referred to collectively, they will be referred to as the "three basic members" as necessary.

[0014] [First Example] 1 to 4 show a first embodiment of the present invention. An earring 10 according to the first embodiment of the present invention includes a first member 110, a second member 120, a third member 130, a pivot pin 160 (connecting pivot), and a friction resistance member 170.

[0015] [First member 110] The first member 110 has a substantially semicircular shape, and a first clamping portion 111 for clamping the user's earlobe is provided at the tip of the first member 110. Also, an axial hole 112 is formed at the base end of the first member 110, and an axial pin 160 is inserted through this axial hole 112, so that the first member 110 and the axial pin 160 are connected in a rotatable state.

[0016] [Second member 120] The second member 120 has a substantially semicircular shape, and a second clamping portion 121 for clamping the user's earlobe is provided at the tip of the second member 120. In addition, an axial hole 122 is formed at the base end of the second member 120, and an axial pin 160 is inserted through this axial hole 122, so that the second member 120 and the axial pin 160 are connected in a rotatable state.

[0017] A first clamping portion 111 that clamps the earlobe and a second clamping portion 121 that clamps the opposite side of the earlobe are disposed opposite to each other.

[0018] [Third member 130] The third member 130 has a substantially semicircular shape, and a third clamping portion 131 for clamping the user's earlobe is provided at the tip of the third member 130. Also, an axial hole 132 is formed at the base end of the third member 130, and an axial pin 160 is inserted through this axial hole 132, so that the third member 130 and the axial pin 160 are connected in a rotatable state.

[0019] The first clamping portion 111 that clamps the earlobe and the third clamping portion 131 that clamps the opposite side of the earlobe are disposed opposite each other. The second member 120 and the third member 130 are disposed in parallel with the first member 110 sandwiched therebetween.

[0020] [Axle pin 160] The pivot pin 160 is basically in the shape of a long and thin cylinder (rod shape) and serves as a connecting shaft that rotatably connects (axially attaches) each of the three basic components of the earring 10. That is, each of the three basic components is mutually rotatably connected by the pivot pin 160.

[0021] After the shaft is attached, both ends of the shaft pin 160 may be crimped to enhance the prevention of the shaft pin 160 from falling off.

[0022] [Friction resistance member 170] The friction resistance member 170 is generally disk-shaped and has a through hole in its approximate center through which the shaft pin 160 can be inserted.

[0023] A frictional resistance member 170 is interposed (or inserted or fitted) between the shaft hole 112, through which the shaft pin 160 is inserted, and the shaft hole 122. Similarly, a frictional resistance member 170 is interposed (or inserted or fitted) between the shaft hole 112, through which the shaft pin 160 is inserted, and the shaft hole 132.

[0024] Furthermore, friction resistance members 170 may also be disposed on the outsides of the second member 120 and the third member 130 and axially attached to the shaft pins 160 .

[0025] The friction resistance member 170 may be not only a metal washer such as a flat washer, a round washer, a disc spring, or a spring washer, but also a non-metallic washer such as a resin washer.

[0026] The friction resistance member 170 generates friction resistance (frictional force) so that a load is applied to each rotation of the three basic members when they rotate. This frictional force allows the earring 10 to maintain a state in which it is clamped around the earlobe (worn state).

[0027] [Effects of the first embodiment] The earlobe of the user can be clamped between the first clamping portion 111 and the second clamping portion 121, and can also be clamped between the first clamping portion 111 and the third clamping portion 131. In other words, the earring 10 can be worn on the earlobe with the earlobe clamped twice.

[0028] When wearing the earring 10, it is possible to rotate either the second member 120 or the third member 130 individually (i.e., independently of each other), so the force required to rotate the second member 120 or the third member 130 can be reduced compared to conventional earrings in which the second member 120 and the third member 130 are integrally constructed.

[0029] In the first embodiment, the force required can be reduced to approximately half, so that the earring 10 can be easily attached to and removed from the earlobe.

[0030] In other words, by increasing the number of components for clamping the earlobe and rotating each one individually, the force required to put the earring 10 on and take it off the earlobe can be reduced, making it easier to put on and take off the earring.

[0031] Furthermore, since the earring 10 does not apply a biasing force in a direction that pinches the wearer's earlobe, pain in the wearer's earlobe can be reduced.

[0032] [Modification 1 of the first embodiment] 5 shows Variation 1 of the first embodiment. The earring 10A, which is Variation 1 of the first embodiment, includes a first member 110, a second member 120, a third member 130, and a friction resistance member 170.

[0033] [First member 110(2)] An axis portion 113 protruding in the rotation axis direction (both front and rear directions) is formed at the base end of the first member 110, and the axis portion 113 can be inserted into an axis hole 122 provided at the base end of the second member 120, and the axis portion 113 can also be inserted into an axis hole 132 provided at the base end of the third member 130.

[0034] The shaft portion 113 serves as a connecting shaft that rotatably connects (axles) the three basic members of the earring 10A, and plays a role similar to that of the pivot pin 160 in the earring 10.

[0035] [Earm fitting 180] An earmuff member 180 is attached to each of the tip end of the first member 110 and the tip end of the second member 120. This earmuff member 180 may be made of resin or silicone.

[0036] To prevent slipping, the tip of earmuff member 180 may have small projections and recesses. Earmuff member 180 may be attached to the tip of each of first member 110 and second member 120 by adhesive such as glue, or may be removably attached.

[0037] By attaching the earmuff member 180, it is possible to increase the friction with the earlobe and prevent the earmuff member from slipping off the earlobe. By covering the earmuff member 180, it is possible to further reduce pain in the user's earlobe.

[0038] For the sake of convenience, even when the earmuff member 180 is attached to the tip of the basic three components (e.g., 10A, 10B), the same symbols and names will be used as when the earmuff member 180 is not attached (e.g., 10, 10D). Detailed illustration of the shape of the earmuff member 180 will be omitted.

[0039] The first clamping portion 111 , the second clamping portion 121 and the third clamping portion 131 may each include an earmuff member 180 .

[0040] [Effects of Modification 1 of the First Embodiment] Since the shaft portion 113 formed on the first member 110 serves as the connecting shaft of the earring 10A, the load (frictional resistance) applied to the rotation of the first member 110 becomes relatively greater than the load (frictional resistance) applied to the rotation of the second member 120 and the third member 130.

[0041] By increasing the load (frictional resistance) when the first member 110 rotates, it is possible to stabilize the wearing state of the earring 10A.

[0042] [Modification 2 of the first embodiment] 6 and 7 show a second variation of the first embodiment. The second variation of the first embodiment, an earring 10B, includes a first member 110, a second member 120, a third member 130, a shaft pin 160 (connecting shaft), a friction resistance member 170, and a shaft portion forming member 210.

[0043] [Shaft forming member 210] The shaft portion forming member 210 has an elongated, approximately cylindrical shape with an approximately C-shaped end face and cross section, and is open at both ends in the axial direction, and is made of an elastic member that has elastic force that causes it to shrink or expand in the radial direction perpendicular to the axial direction.

[0044] The center of the shaft portion forming member 210 in the axial direction is hollow, forming a hollow portion 212. Also, a linear slit portion 211 is formed in the axial direction.

[0045] [First member 110(3)] The first member 110 has an axial hole 112 at its base end, and a protrusion 114 is formed on the inner wall of the axial hole 112. This protrusion 114 can be fitted into a slit portion 211, and after assembly, the first member 110 and the shaft portion forming member 210 move in conjunction with each other when they rotate.

[0046] [Effects of Modification 2 of the First Embodiment] When the shaft portion forming member 210 made of an elastic member is inserted into the shaft hole 112 of the first member 110, the shaft portion forming member 210 can be inserted in a state where it is compressed radially inward.

[0047] After assembly, the elastic force (restoring force) of the shaft forming member 210 acts to bias the ears radially outward, increasing the load (friction resistance) generated when each of the three basic members rotates. This makes it possible to stabilize the earring 10B when worn on the earlobe.

[0048] [Modification 3A of the First Embodiment] 8 to 11 show a variation 3A of the first embodiment. The earring 10C, which is the variation 3 of the first embodiment, includes a first member 110, a second member 120, a third member 130, a shaft pin 160 (connecting shaft), a friction resistance member 170, and a biasing member 220.

[0049] [Using member 220] The biasing member 220 is a thin plate folded in two, with a hollow portion in the center. The side surface of the biasing member 220 is roughly V-shaped, and the base end of the first member 110 can be inserted into the hollow portion of the biasing member 220, and the biasing member 220 is fitted (fitted) to the base end of the first member 110.

[0050] The biasing member 220 is positioned to abut against the curved surfaces formed at the base end of the second member 120 and the base end of the third member 130, and has a biasing force that biases the second member 120 and the third member 130 to rotate so that the second member 120 and the third member 130 are stably positioned.

[0051] The biasing member 220 may be made not only of a metal having spring properties, but also of a non-metallic material such as rubber or resin, such as silicone.

[0052] [Effects of Modification 3A of the First Embodiment] The second member 120 and the third member 130 are stably arranged by the biasing force of the biasing member 220 fitted (attached) to the base end of the first member 110. This makes it possible to stabilize the wearing state of the earring 20.

[0053] [Modification 3B of the First Embodiment] 12 to 14 show a variation 3B of the first embodiment. The earring 10C′, which is variation 3B of the first embodiment, includes a first member 110, a second member 120, a third member 130, an axle pin 160 (connecting axle), a friction resistance member 170, and a biasing member 220.

[0054] Earring 10C' has substantially the same configuration as earring 10C, but second member 120 and third member 130 have polygonal end faces formed at their proximal ends.

[0055] In FIG. 13, since the biasing member 220 abuts against the corners (i.e., the branching points of the biasing force) of the polygonal end faces formed at the base ends of the second member 120 and the third member 130, respectively, the biasing force of the biasing member 220 does not contribute to the rotation of the second member 120 and the third member 130, and the second member 120 and the third member 130 remain unstably stationary in this state.

[0056] However, when the second member 120 (and / or the third member 130) rotates even slightly, the biasing member 220 biases the second member 120 (and / or the third member 130) to rotate in the same direction as the slight rotation.

[0057] Specifically, FIG. 12 shows the second member 120 (and / or the third member 130) rotated slightly outward from the rest state of FIG. 13, and the biasing force of the biasing member 220 causes the second member 120 (and / or the third member 130) to rotate further outward relative to the first member 110, until the biasing member 220 stabilizes against one of the flat end faces adjacent to the corner of the polygon.

[0058] On the other hand, FIG. 14 shows a state in which the second member 120 (and / or the third member 130) has been rotated slightly inward from the stationary state of FIG. 13, and the biasing force of the biasing member 220 causes the second member 120 (and / or the third member 130) to rotate further inward relative to the first member 110, until the biasing member 220 stabilizes in abutment against the other flat end face adjacent to the corner of the polygon.

[0059] By adjusting the angle between the first member 110 and the second member 120, and the angle between the first member 110 and the third member 130, it is possible to control the biasing force of the biasing member 220.

[0060] The biasing force and clamping force can be adjusted by adjusting the angle between the end faces of the polygon and the number of corners. In other words, the biasing force can be adjusted by prior design.

[0061] [Effects of Modification 3B of the First Embodiment] The second member 120 and the third member 130 are stably arranged by the biasing force of the biasing member 220 fitted (attached) to the base end of the first member 110. This makes it possible to stabilize the wearing state of the earring 20.

[0062] [Modification 4 of the First Embodiment] 15 to 18 show Variation 4 of the first embodiment. Earring 10D, which is Variation 4 of the first embodiment, includes a first member 110, a second member 120, a third member 130, a base member 150, an axle pin 160 (connecting axle), and a friction resistance member 170. The three basic members and base member 150 are connected to each other by the axle pin 160 so as to be rotatable.

[0063] [Base member 150] The base member 150 includes a pair of plate portions 151, which are bridged below by a bridge portion 153. Each of the pair of plate portions 151 is formed with an axial hole 152 through which an axial pin 160 can be inserted. The surface of the plate portion 151 may be coated to reduce contact resistance.

[0064] The friction resistance members 170 are respectively positioned and interposed (or interposed or interposed) on both axial sides of the axial hole 112 at the base end of the first member 110, on the axial outside of the axial hole 122 at the base end of the second member 120, and on the axial outside of the axial hole 132 at the base end of the third member 130.

[0065] At least one of the side walls of the first member 110 is formed with a protrusion 115 protruding in the axial direction, the inner side wall of the second member 120 is formed with a protrusion 125 protruding in the axial direction, and the inner side wall of the third member 130 is formed with a protrusion 135 protruding in the axial direction.

[0066] When the first member 110 rotates, the protrusion 115 abuts against the wall surface of the base member 150, thereby limiting the range in which the first member 110 can rotate. Also, when the second member 120 rotates, the protrusion 125 abuts against the wall surface of the base member 150, thereby limiting the range in which the second member 120 can rotate.

[0067] Furthermore, when the third member 130 rotates, the protrusion 135 comes into contact with the wall surface of the base member 150, so that the range within which the third member 130 can rotate can be limited.

[0068] [Effects of Modification 4 of the First Embodiment] The presence of the base member 150 makes it possible to suppress a phenomenon in which, when the first member 110 is rotated, the second member 120 or the third member 130 rotates together with the first member 110 (called a "co-rotation phenomenon").

[0069] By suppressing the rotational phenomenon, the independence of rotation of the three basic components can be increased, thereby improving the operability when putting on and taking off the earring 10D.

[0070] [Second Example] Figures 19 and 20 show a second embodiment. The second embodiment, an earring 20, includes a first member 110, a second member 120, a third member 130, a fourth member 140 (described below), a connecting member 150, a pivot pin 160, a friction resistance member 170, and a friction reduction member 190 (described below).

[0071] When referring to the first member 110, the second member 120, the third member 130, and the fourth member 140 collectively, they will be referred to as the "four main members" as necessary.

[0072] The first member 110 and the second member 120 are disposed opposite each other, and the third member 130 and the fourth member 140 are disposed opposite each other. The first member 110 and the fourth member 140 are disposed in parallel in the rotation axis direction with the third member sandwiched therebetween, and the second member 120 and the third member 130 are disposed in parallel in the rotation axis direction with the first member 110 sandwiched therebetween.

[0073] Furthermore, a friction reducing member 190 is disposed between the first member 110 and the third member 130. The four main members and the base member 150 are connected (axially attached) by a shaft pin 160 so as to be rotatable relative to one another.

[0074] The friction resistance members 170 are disposed between the first member 110 and the second member 120, between the third member 130 and the fourth member 140, and on both sides of the friction reduction member 190, and are interposed between the shaft pins 160.

[0075] [Fourth member 140] The fourth member 140 has a substantially semicircular shape, and a fourth clamping portion 141 for clamping the user's earlobe is provided at the tip of the fourth member 140. In addition, an axial hole 142 is formed at the base end of the fourth member 140, and an axial pin 160 is inserted through this axial hole 142, so that the fourth member 140 and the axial pin 160 are connected in a rotatable state.

[0076] The fourth clamping portion 141 faces the third clamping portion 131 that clamps the earlobe, and the fourth member 140 is disposed on the outer side (right side) in the axial direction of the third member 130. The four main members may each have approximately the same shape.

[0077] [Base member 150(2)] The base member 150 includes a pair of plate portions 151, and the pair of plate portions 151 are bridged at the bottom by a bridge portion 153. Further, each of the pair of plate portions 151 is formed with an axial hole 152 through which an axial pin 160 can be inserted.

[0078] A recess 154 is provided substantially in the center of the bridge portion 153, and this recess 154 can be fitted into a protrusion 193 provided below a friction reduction member 190, which will be described later.

[0079] [Friction reducing material 190] The friction reduction member 190 has a plate-shaped plate portion 191, and a shaft hole 192 through which the shaft pin 160 can be inserted is formed in the plate portion 191. A convex portion 193 is provided on the lower side (bottom surface) of the friction reduction member 190, which fits into a concave portion 154 of the bridge portion 153, so that the base member 150 and the friction reduction member 190 rotate in conjunction with each other. The surface of the plate portion 191 may be coated to reduce contact resistance.

[0080] [Effect of friction reduction member 190] The frictional resistance force between the first member 110 and the third member 130 via the friction reduction member 190 is lower than the frictional resistance force between the first member 110 and the second member 120 and between the third member 130 and the fourth member 140.

[0081] In other words, the friction reduction member 190 can reduce the influence of the rotation of the first member 110 and the third member 130.

[0082] The friction reduction member 190 reduces the phenomenon in which friction affects each other between members that share an axis (co-rotation phenomenon), making it possible to smoothly open and close the earring 20 and to easily put on and take off the earring.

[0083] [Effects of the second embodiment] In addition to being clamped by the first clamping portion 111 of the first member 110 and the second clamping portion 121 of the second member 120, the earlobe can be clamped doubly by being clamped by the third clamping portion 131 of the third member 130 and the fourth clamping portion 141 of the fourth member 140.

[0084] This amplifies the clamping force that clamps the earring 20, i.e., the frictional resistance that occurs when the four main components rotate, thereby stabilizing the wearing state of the earring 20.

[0085] [Modification of the second embodiment] 21 and 22 show the second embodiment. The earring 20A of the second embodiment includes a first member 110, a second member 120, a third member 130, a fourth member 140, a friction resistance member 170, and an intermediate member 230 described below. The four main members and the intermediate member 230 are connected (axially attached) to each other so as to be rotatable.

[0086] [Intermediate part 230] Intermediate member 230 has shaft portion 231 and is provided with connecting portion 232 to which an ornament such as an end part can be connected. Shaft portion 231 is inserted through shaft hole 112, shaft hole 122, shaft hole 132, and shaft hole 142, and shaft portion 231 serves as a connecting shaft of earring 20A.

[0087] The friction resistance members 170 are disposed on the outer side of the second member 120 , the outer side of the fourth member 140 , and on both sides of the intermediate member 230 , and are interposed between the shaft portions 231 .

[0088] [Effects of the modification of the second embodiment] Like earring 20, earring 20A can clamp the earlobe doubly by being clamped by first clamping portion 111 of first member 110 and second clamping portion 121 of second member 120, as well as by being clamped by third clamping portion 131 of third member 130 and fourth clamping portion 141 of fourth member 140.

[0089] The intermediate member 230 allows a jewelry body to be connected to the lower part of the earring 20A, thereby enhancing the decorativeness of the earring.

[0090] [Third Example] 23 to 25 show a third embodiment of the earring 30. The third embodiment of the earring 30 includes a first member 110, a second member 120, a third member 130, a fourth member 140, a base member 150, a pivot pin 160, a friction resistance member 170, and a friction reduction member 190.

[0091] The first member 110 and the second member 120 are disposed facing each other, and the user's earlobe can be clamped between the first clamping portion 111 and the second clamping portion 121. The four main members and the base member 150 are connected (axially attached) to each other by a pivot pin 160 so as to be rotatable.

[0092] [Third member 130 and fourth member 140] In earring 30, third member 130 and fourth member 140 do not directly clamp against the wearer's earlobe.

[0093] An abutment portion 133 capable of abutting against the first member 110 is formed on the tip side of the third member 130, and an abutment portion 143 capable of abutting against the second member 120 is formed on the tip side of the fourth member 140. In addition, the third member 130 is disposed on the side facing the second member 120, and the fourth member 140 is disposed on the side facing the first member 110.

[0094] [Base member 150(3)] A protrusion 155 is formed on the front side of the base member 150, and when the fourth member 140 rotates, this protrusion 155 abuts against the lower side wall of the fourth member 140, thereby limiting the range within which the fourth member 140 can rotate.

[0095] In addition, a protrusion 155 is formed on the lower side wall of the base member 150, and when the third member 130 rotates, the right side surface of the third member 130 comes into contact with this protrusion 155, thereby limiting the range within which the third member 130 can rotate.

[0096] [Effects of the third embodiment] When the first member 110 rotates outward (clockwise in the figure), the abutment portion 133 of the third member 130 presses against the right side wall of the first member 110, thereby increasing the frictional resistance to the rotation of the first member 110 and suppressing the rotation of the first member 110.

[0097] When the second member 120 rotates outward (counterclockwise in the figure), the abutment portion 143 of the fourth member 140 presses against the left side wall of the second member 120, thereby increasing the frictional resistance to the rotation of the second member 120 and suppressing the rotation of the second member 120.

[0098] This amplifies the clamping force that clamps the earring 30, i.e., the frictional resistance that occurs when the four main components rotate, thereby stabilizing the wearing state of the earring 30.

[0099] Furthermore, the presence of the base member 150 makes it possible to suppress a phenomenon in which when one of the four main members rotates, the other four main members rotate together (called the "together rotation phenomenon").

[0100] By suppressing the rotational phenomenon, the independence of rotation of the four main components is increased, improving the operability when putting on and taking off the earring 10D.

[0101] [material] In the first to third embodiments of the earring of the present invention described above, the first member 110, the second member 120, the third member 130, the fourth member 140, the base member 150, the pivot pin 160, the friction resistance member 170, the friction reduction member 190, the shaft forming member 210, the biasing member 220, and the intermediate member 230 can be made of metal materials such as silver, copper, stainless steel, titanium, etc., ceramics, plastics, etc. Also, each member may be made of a different material.

[0102] Although the earrings having two mutually rotatable members arranged in parallel have been described above, the present invention is not limited to this structure. If the earrings have a structure in which three mutually rotatable members are arranged in parallel, the force required to rotate the members can be reduced to approximately 1 / 3. Furthermore, if the earrings have a structure in which four mutually rotatable members are arranged in parallel, the force required to rotate the members can be reduced to approximately 1 / 4.

[0103] A preferred embodiment of the present invention has been described above, but since this embodiment is merely one form of earrings according to the present invention, modifications can be made without departing from the spirit of the present invention.

[0104] It should be noted that the drawings are schematic representations of the components of the earrings, and the actual dimensions and dimensional ratios of these components do not necessarily match the dimensions and dimensional ratios shown in the drawings. [Industrial Applicability]

[0105] As described above, the earring of the present invention can be provided as an earring (ear accessory) that is convenient for the user. [Explanation of symbols]
