It is a schematic diagram which shows an example of the fastener for a conventional accessory.

Conventionally, the fastener 100 shown in FIG. 8 is widely known as an accessory fastener. The fastener 100 includes a connecting plate 110 which is an example of a connected fastening member on the connecting side, and a pull ring 120 which is an example of a connecting fastening member on the connecting side. The connecting plate 110 is a substantially oblong flat plate, and has two through holes at both ends in the longitudinal direction. The through hole on the rear end side is a mounting hole 111 for attaching a chain member (linear member), and the through hole on the front end side is a connecting hole 113 for connecting the pull ring 120 so that it can be separated (disconnected). Is. The pull ring 120 is a substantially annular member including an opening / closing member 121 having an opening lever 122 and a main body portion 123. The opening lever 122 is urged to be closed by an urging means (not shown). The inner space of the annular member is a holding space 125 for holding the tip end side of the connecting plate 110. By opening and closing the opening / closing member 121, the holding space 125 can be opened and closed.

An example of wearing an accessory (necklace, etc.) equipped with this fastener 100 will be described. The user holds the connecting plate 110 and the pulling wheel 120 in both hands, respectively, and connects them as follows.

First, the user holds the rear end side of the connecting plate 110 with one hand so that the connecting hole 113 is not hidden. At this time, the longitudinal direction of the connecting plate 110 is set so as to substantially coincide with the directions of the thumb and index finger of one hand so that the position of the connecting hole 113 can be inferred even if it is not visible. Further, the user operates the opening lever 122 with his / her fingertip or a nail to open the opening lever 122, and creates an insertion port 127 in the pull ring 120 which is a gap connected to the holding space 125. At this time, the insertion port 127 is in a state of being positioned on the tip end side of the fingertip of the other hand so that the connection operation can be easily performed.

The user brings the connecting plate 110 and the pull ring 120 of the fingertips to the back side of the neck while maintaining the above-mentioned state. Then, the tip of the connecting plate 110 and the pulling ring 120 are brought close to each other, and the position of the insertion port 127 of the pulling ring 120 is found out from the contact condition between the members and the like, and the alignment is performed. After that, the tip end portion of the connecting plate 110 is inserted into the holding space 125, and the connecting hole 113 is hung through the opening end 127b of the main body portion 123. The double fastening members 110 and 120 (connecting plate 110 and pulling ring 120) are slightly pulled, and when the hooking is confirmed, the opening lever 122 is returned to the original position to close the insertion port 127, and the holding space 125 is closed. In this way, the connecting hole 113 of the connecting plate 110 is hooked to the opening / closing member 121 and connected to the pull ring 120.

Here, the connection operation of the

double fastening members

110 and 120 is an operation performed on the back side of the neck, and the user cannot visually recognize it. As described above, since the position of the insertion port 127 is searched while finely adjusting the positions of the double-

sided fastening members

110 and 120 only by the feeling of the hand, the alignment operation is not easy. Further, both

fastening members

110 and 120 are members smaller than the fingertips. Even if you hold the

fastening members

110 and 120 with your fingertips so that they are in an appropriate state for the connection operation at first, the

fastening members

110 and 120 or your fingertips collide with each other when aligning on the back side of the neck. As a result, the holding position sometimes shifted. In particular, the plate-shaped connecting plate 110 is slippery at the fingertips, and the orientation of the connecting holes 113 may change or the connecting holes 113 may be hidden by the fingertips.

When wearing jewelery along the neck, the length of the jewelery is short, so bring both hands to the back of the back of the neck (for example, around the 7th cervical spine) and perform the above-mentioned connection operation. There is. If you bring both hands to this position, both forearms and both hands will be in a V-shaped posture, and in the natural posture, the fingertips of both hands holding the two

fastening members

110 and 120 will face diagonally downward. It ends up. In this position, the index fingers of both hands get in the way, and the connection operation cannot be performed well. Further, in order to smoothly insert the tip end side of the connecting plate 110 into the insertion port 127 of the pull ring 120, the insertion port 127 and the tip end side of the connecting plate 110 are opposed to each other, and the opening direction of the insertion port 127 (both openings). It is desirable to have a positional relationship such that the direction through which the

ends

127a and 127b pass) and the thickness direction of the connecting plate 110 are substantially parallel. However, in order for the two

fastening members

110 and 120 to have such a positional relationship, it is necessary to twist both arms and both hands outward. It is a burden for the user to maintain a twisted posture near the back, and it may be painful to perform the above-mentioned connection operation in such an unreasonable posture.

Patent Documents 1 to 3 disclose a connected fastening member having a shape different from that of the connecting plate 110, which is a conventional connected fastening member. However, the entire connected fastening member is still flat, and the connecting operation cannot be easily performed as in the case of the connecting plate 110 which is the above-mentioned connected fastening member. Further, when the surface of the member is roughened or a part of the member is made into a blade shape as in Patent Documents 1 and 2, there is a risk that the accessory may be slightly scratched during storage. rice field. In addition, although the connected fastener was used as a part of jewelry, it was poorly decorative.

Patent Document 4 discloses a specially shaped connecting fastener member (female portion) and a connected fastening member (male portion) used for the connecting fastener. The insertion port of the female part is provided at a position on the thumb side when the user holds the female part. The tip of the male part extends in a Y shape, and the body part has an elliptical plate shape perpendicular to the Y shape. A shaft, which is a separate member, is attached to the inside of both ends extending in a Y shape, and a connecting hole is formed by the Y-shaped portion and the shaft.

The male part of Patent Document 4 picks the body part perpendicular to the Y shape. It seems that it is easy to hold because there is no mounting hole in the part to be picked. However, since the body portion is plate-shaped, it is slippery like the connected fastening member described in Patent Document 1 and the like. In particular, this fastener is configured so that the insertion direction of the male portion is parallel to the lateral direction of the body portion. Therefore, when the shaft of the male part is brought into contact with the opening / closing member of the female part and an upward force is applied in the insertion operation, the shaft side of the male part slides so as to rotate downward, and the connection cannot be performed well. Further, the shaft of the male portion and the Y-shaped portion are separate members, and the rod-shaped shaft is supported by only two points inside the Y-shaped tip. Therefore, when the linear member is pulled, the force is concentrated only on the two support points. As a result, it is considered that the round bar-shaped shaft is bent or the distance on the tip side of the Y-shape is widened, and the shaft is deformed due to use, and there is a risk that the shaft will come off and the accessory will be lost.

Here, in the invention according to Patent Document 4, a female portion having a specific shape is an indispensable component, and it is not considered to substitute another connected fastener (for example, a pull ring type). Therefore, for example, when used in combination with a pull ring or the like, the thick Y-shaped portion interferes with the alignment, and it is difficult to easily connect them. Further, the male part has a complicated structure as compared with the conventional connecting plate and the like, and the Y-shaped part has a certain thickness to support the round bar, so that it takes time and cost to manufacture. It was expensive. Further, in the male part, the Y-shaped part has an angular shape, and it cannot be said that the decorativeness is taken into consideration.

The articulated fastening member for jewelry of the present disclosure was devised in view of the above-mentioned problems, and can be easily connected to the connecting fastening member as compared with the conventional connecting fastening member such as a connecting plate. It is something that can be done. Specifically, in the accessory to be connected fastener member of the present disclosure, the direction of the normal line of the plate surface of the portion to be pinched by the fingertip and the penetrating direction of the connecting hole (the axis of the penetrating hole) are in a twisting relationship. Since it is formed in, the user can easily perform the connection operation of the accessory. Hereinafter, an example of a preferred embodiment of the accessory-attached fastening member of the present disclosure will be described together with the accessory and the accessory fastening member with reference to the drawings.

The connecting portion 60 has a rising surface (in this embodiment, a twisted inclined surface 62) that rises from the plate surface of the knob portion 50. The rising surface is positioned when the user holds the grip portion 50 of the connected fastening member 40. Further, when the tip of the finger comes into contact with the rising surface, it functions as a non-slip to prevent the finger from slipping toward the tip side (direction of arrow C) when performing the connection operation. Further, if the rising surface is an inclined surface that is twisted and inclined in the longitudinal direction (C direction), it fits into the curved surface of the tip of the fingertip and is easy to hold. The shape of the connecting portion 60 is not limited to the one described above, and may have a rising surface that functions as a non-slip to prevent the finger from slipping toward the tip end side (direction of arrow C). The connected fastening member 40 may have a configuration in which the connecting portion 60 is not provided. For example, only the knob portion 50 and the connecting portion 70 having the above-mentioned shape are arranged in the longitudinal direction, and the tip of the knob portion 50 is twisted so that the relationship between the normal line of the knob portion 50 and the axis of the connecting hole 73 is in a twisted relationship. It may be configured so that the end face on the side and the end face on the rear end side of the connecting portion 70 come into contact with each other. In this case, the rising surface is the end surface on the rear end side of the connecting portion 70.

The two twisted inclined surfaces 62 are continuously twisted and inclined from the end of the knob 50 on the connecting portion 60 side toward the end of the connecting portion 70 on the connecting portion 60 side. The two twisted inclined surfaces 62 have curved portions that are wound in directions facing each other. When the gripped portion 50 is pinched with two fingers, the two curved portions are projected toward the abdomen of each fingertip, so that the connected fastening member 40 is prevented from slipping in the B direction. Can be done. Further, the side surface of the connecting rear end portion 75 can be sandwiched between both claws so that the claws of each finger touch the side surface. Therefore, even if the connected fastening member 40 collides with the connecting fastening member 30 or the like during the connecting operation, the holding position is unlikely to shift. Further, even if they collide with each other, the position of the side surface of the connecting rear end portion 75 can be confirmed with a fingertip, so that the position of the connecting hole 73 can be estimated. Further, since the position of the connecting hole 73 can be estimated, for example, the connecting hole 73 is held diagonally so as to protrude in the direction opposite to the back side without aligning the longitudinal direction of the connected fastening member 40 with the directions of the two fingertips. , The connected fastening member 40 can be connected to the connecting fastening member 30. By holding it in this way, it is possible to avoid collision of fingers and entanglement with hair during the connection operation. Further, in this case, the insertion direction of the connecting fastening member 30 into the opening 39 (see FIG. 7) may deviate laterally from the distal end side (inserting portion 71X) of the peripheral edge portion of the connecting hole 73, so that the connecting hole It is preferable that the peripheral edge portion of 73 has a constant thickness over a wide range (for example, the tip end side portion 71Y or the connecting tip portion 71).

In the present embodiment, the grip portion 50 is provided with a mounting hole 53, and its diameter is relatively large, which is approximately ½ of the length of the grip portion 50 in the longitudinal direction (left-right direction in FIG. 3). When picked with a fingertip, for example, a circular ring attached to the attachment hole 53 is pressed against the pad of the finger to exert a non-slip function. Further, the positional relationship between the circular ring and the connecting portion 60 can be felt with a fingertip, and the orientation of the connected fastening member 40 and the position of the connecting hole 73 can be easily estimated. The proportion of the knob portion 50, the connecting portion 60, and the connecting portion 70 in the longitudinal direction of the accessory fastening member 40 is not particularly limited. From the viewpoint of facilitating the connection operation of the accessories, the connecting portion 60 is preferably in the range of about 1/5 to about 1/3 with respect to the total length in the longitudinal direction.

Both ends of the connecting portion 60 are inclined start positions 64, and the twisted inclined surface 62 of the connecting portion 60, the plate surface of the knob portion 50, and the plate surface of the connecting portion 70 are gently continuous surfaces. There is. Therefore, in the case of a bracelet that is connected with one hand, the tip of the connecting fastening member 30 can be guided into the connecting hole 73 along the twisted inclined surface 62 by using the rolled portion of the twisted inclined surface 62. ..
