(Summary)
According to the accessory 1 according to the above-described embodiment, the following effects can be obtained.

  (1) The accessory 1 includes a first member 3 and a second member 4 that form a gap 2 in which an object such as an earlobe can be inserted, and a connecting portion that rotatably connects the first member 3 and the second member 4. 5 and a rotation inhibiting portion 6 that releasably inhibits the rotation of the first member 3 and the second member 4 at a plurality of rotation positions, and the first member 3 and the second member 4 The gap 2 changes with the rotation of.

  According to this configuration, the operation of turning the screw as in the case of the screw earring is unnecessary, and the gap 2 can be adjusted only by rotating the first member 3 and the second member 4. Therefore, the gap 2 can be easily adjusted, and the attachment and detachment of the accessory 1 can be performed very easily. In addition, since the rotation of the first member 3 and the second member 4 is suppressed stepwise at a plurality of rotation positions, it is possible to adjust the gap 2 to a desired value that matches the size of the object (earlobe, etc.) to be sandwiched. It becomes possible. Thereby, it can be effectively prevented that the gap 2 is too narrow and the wearing feeling is reduced, and that the gap 2 is too wide and easily dropped.

  Further, according to this configuration, compared to a case where a frictional force for suppressing the rotation is exerted continuously at all the rotation positions (for example, an earring described in Patent Document 1), the rotation position due to wear of the parts and the like is reduced. Deterioration of the holding function is easily suppressed. That is, when the rotation is continuously suppressed by the frictional force, the frictional force is exerted at all the rotation positions, so that as the wear of the parts progresses, the deviation of the rotation position is apt to occur gradually, and accordingly, The accessory 1 is likely to fall off gradually. On the other hand, according to the rotation suppressing portion 6 of the accessory 1, since the rotation of the first member 3 and the second member 4 is releasably suppressed at each of the plurality of rotation positions, wear of the parts is reduced. As long as the movement does not proceed to a certain extent, the rotation of each rotation position can be stably suppressed. Therefore, deterioration of the function of holding the gap 2 can be effectively suppressed, and the service life can be prolonged.

  (2) The rotation suppressing portion 6 includes a first engaging portion 61 provided on the first member 3 and a plurality of second engaging portions 62 provided on the second member 4 (examples of FIGS. 5 and 6). And eight second engagement portions 62), and each of the plurality of second engagement portions 62 can be engaged with the first engagement portion 61. The plurality of rotation positions where the rotation of the first member 3 and the second member 4 is suppressed and the plurality of second engagement portions 62 correspond one-to-one, and rotate at one rotation position. Is suppressed, the one second engagement portion 62 and the first engagement portion 61 corresponding to the one rotation position are engaged.

  According to this configuration, the rotation between the first member 3 and the second member 4 is suppressed by the engagement between the first engagement portion 61 and the second engagement portion 62. Therefore, the rotation position of the first member 3 and the second member 4 is stably maintained as compared with the case where the rotation is suppressed by the frictional force of the hinge part as in the earring described in Patent Document 1. it can.

  (3) When at least one of the first engagement portion 61 and the second engagement portion 62 is elastically deformed, the engagement between the first engagement portion 61 and the second engagement portion 62 is released.

  According to this configuration, unless at least one of the first engagement portion 61 and the second engagement portion 62 is elastically deformed, the first engagement portion 61 and the second engagement portion 62 are engaged. Becomes Accordingly, the engagement state between the first engagement portion 61 and the second engagement portion 62 can be stably maintained while having a relatively simple structure.

  (4) Each of the plurality of second engaging portions 62 includes a concave portion 621 recessed toward the rotation axis AX, and the end portion 611 of the first engaging portion 61 and the concave portion 621 can be engaged. As the distance between the rotation axis AX of the connecting portion 5 and the end 611 of the first engaging portion 61 changes with the elastic deformation of the first engaging portion 61, the first engaging portion 61 and the recess 621 are formed. Is disengaged.

  According to this configuration, since the concave portion 621 recessed toward the rotation axis AX and the end portion 611 of the first engagement portion 61 are engaged, the rotation of the first member 3 and the second member 4 is performed. Since the rotation is suppressed, the rotation position of the first member 3 and the second member 4 can be stably maintained compared to the case where the rotation is suppressed by the frictional force of the hinge part. Further, when the first engaging portion 61 is elastically deformed, the distance between the end 611 of the first engaging portion 61 and the rotation axis AX changes, and the engagement between the first engaging portion 61 and the concave portion 621 occurs. Is released, it is possible to suppress the rotation of the first member 3 and the second member 4 and release the rotation while having a relatively simple structure.

  (5) The first engagement portion 61 has a band-like shape that can be elastically deformed along a virtual plane VP perpendicular to the rotation axis AX, and has one end 611 in the longitudinal direction of the first engagement portion 61. The recess 621 can be engaged.

  According to this configuration, since the first engaging portion 61 having a band shape can be elastically deformed along the virtual plane VP, the longitudinal direction of the first engaging portion 61 is along the virtual plane VP. Further, since one end 611 in the longitudinal direction of the first engaging portion 61 and the concave portion 621 can be engaged, the concave portion 621 of the second engaging portion 62 is located on the virtual plane VP. Therefore, the thickness of the accessory 1 in a direction perpendicular to the virtual plane VP (a direction parallel to the rotation axis AX) can be reduced.

  (6) The concave portions 621 of the plurality of second engagement portions 62 are arranged along the circumference of the virtual circle VC on the virtual plane VP centered on the rotation axis AX (FIGS. 5 and 6).

  According to this configuration, the second engaging portion 62 that engages with the end 611 of the first engaging portion 61 at a plurality of rotation positions where the rotation of the first member 3 and the second member 4 is suppressed. The distance between the concave portion 621 and the rotation axis AX becomes substantially equal. That is, at each of the rotation positions where the rotation is suppressed, the positional relationship between the end 611 of the first engagement portion 61 and the recess 621 of the second engagement portion 62 in the engaged state is substantially equal. Therefore, it is possible to prevent the stability of the engagement between the first engagement portion 61 and the second engagement portion 62 from varying depending on the rotation position.

  (6) The first member 3 regulates the movement of the first engaging portion 61 along the virtual plane VP inside the groove 31 and the groove 31 in which the first engaging portion 61 is arranged, and It includes a restricting portion 33 for restricting the movement of the first engaging portion 61 toward the outside, and a fixing portion 34 for fixing the first engaging portion 61 to the first member 3 at a position separated from the concave portion 621 by the restricting portion 33. .

  According to this configuration, the range of movement of the first engaging portion 61 along the virtual plane VP is controlled by the restricting portion 33 to a desired range even when the first engaging portion 61 having a band shape is relatively long. Can be regulated within. Therefore, desired elastic deformation can be caused in the first engaging portion 61 while preventing the first engaging portion 61 from coming off the first member 3.

  (7) The first engaging portion 61 has a first through hole 613 extending along the virtual plane VP, and the fixing portion 34 includes a first fixing pin 341 inserted into the first through hole 613.

  According to this configuration, the first engaging portion 61 is easily fixed to the first member 3 by inserting the first fixing pin 341 of the fixing portion 34 into the first through hole 613 of the first engaging portion 61. And the assembling work can be simplified.

  (8) The rotation suppressing portion 6 includes the plate-like member 60 in which the concave portions 621 of the plurality of second engaging portions 62 are formed on the side edge portions 601. The material of the plate member 60 is an alloy (hard metal such as stainless steel or tungsten) having a higher hardness than the first member 3 and the second member 4. The plate member 60 has a plurality of second through holes 602 extending in parallel with the rotation axis AX.

  According to this configuration, a plate-like member made of an alloy such as stainless steel or tungsten having a higher hardness and a higher durability than the material used for the second member 4 (for example, a noble metal such as gold, copper, or platinum). A recess 621 of the second engaging portion 62 is formed in 60. Therefore, the service life of the accessory 1 can be further extended. Further, since the ends of the plurality of second fixing pins 44 protruding from the plurality of second through holes 602 of the plate-like member 60 are welded to the pressing member 43, the second member 4 made of a material such as a noble metal can be used. The plate member 60 can be reliably fixed to the second member 4 even when it is difficult to directly weld the plate member 60 made of a high-hardness alloy such as stainless steel.

  (9) The first member 3 includes a pair of arms 32A and 32B facing each other across the virtual plane VP, and the plate member 60 is located between the pair of arms 32A and 32B. The connecting portion 5 includes a shaft member 51 that passes through the pair of arm portions 32A and 32B of the first member 3 and the second member 4.
