Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is capable of attaching a netukure by selectively changing and connecting both ends of the netukure made of pearls, other suitable metals, glass connected beads, etc. The present invention relates to a fastener whose shape and length can be arbitrarily changed. [Prior Art] In a conventional pearl necklace clasp, for example, as shown in Figures 10 and 11, a ring body 12 is formed by bending a thin metal wire into a ring shape on one of the opposing surfaces of the peripheral surface of a pearl 11. It is also known that the other end is held and fixed by a perforated frame 14 made of a thin metal plate integrally formed with a decorative crown 13 on the front side. Furthermore, as disclosed in Japanese Patent Application Laid-Open No. 60-207606, a ball is provided with a through hole, a thread is passed through the hole, and a large number of balls are connected in a string shape and connected in a ring using a stopper. A thread end locking member is provided at one end of the string-like string, and the other end has a through space capable of gripping any part of the netskuress, and a containing portion consisting of two small pieces, and the two small pieces are A stopper is provided, comprising an opening/closing hinge that can be opened wide enough to insert and hold the ball, and a locking part that allows the housing part of the stopper to be locked and unlocked in an annular manner by fingertip operation. There are also known length-adjustable necklaces in which the shape of the container part is formed so that the relative position of the gripped ball and the stopper cannot be changed in the locked state. [Problems to be Solved by the Invention] However, in the former case, in the conventional fastener mentioned above, one side that holds the opposing surfaces of the circumference of the pearl 11 is a ring formed by bending a thin metal wire into a ring shape. Since the pearl body 12 is weak, there is a risk of breakage or deformation during use, and the beauty of the pearl 11 is impaired unless the pearl 11 is always held with the decorative crown body 13 on the front side. Therefore, there were problems such as being troublesome to handle, such as having to be careful about how to fasten the fasteners. In the latter case, it has a stopper that can be opened and closed to hold any part of the netcress in an immovable manner, so it can be adjusted to any desired length and can be used as a decorative netcress with this stopper part in front. ,
It is possible to change the decorativeness of the netcress, but in this case, the length of the netcress is adjusted by a stopper attached only to one end of the netcress.
Compared to those with fasteners attached to both ends, there is less decorativeness and variation in length, and there is a problem that the decorative effect is poor, and the shape of the fastener itself is approximately bowl-shaped in cross section. It is different from that in that it consists of two small pieces in the shape of water droplets (teardrops) that are split vertically from the center, and the openings formed in the two small pieces for exposing the netsukure bead cover the circumferential surface of the bead. Since the ball has a window hole shape that is partially exposed, there was a problem in that the entire circumferential surface of the ball could not be exposed in an annular shape with the required width. This invention solves the above problems, has excellent strength,
The beads are made so that there is no risk of breakage or deformation, and the outer surface of the beads can be held between the beads holding portions of the stopper in a series of substantially annular shapes having the required width, with the beads being largely exposed. The bead can always be held in a stable state without compromising its beauty, and the fastening metal fittings are the same on the front and back, so there is no need to pay attention to the front and back sides of the holding metal fittings when using them. An object of the present invention is to provide a fastener for a beaded necklace that is extremely easy to handle and has a great decorative effect, allowing the manner in which the necklace is attached and the length to be arbitrarily and variously changed during use. It is. [Means for solving the problem] The present invention aims to solve the above problem,
It is attached to both ends of a bead neckless made by connecting a number of beads, and by selectively changing the attachment point to the beads, the manner in which the netless is attached and its length can be changed as desired. This is a stopper for a bead necklace, and the inner surface is formed into a concave arc surface and the outer surface is formed into a convex arc surface so that opposing surfaces of the circumferential surfaces of the beads can be held together. A pair of fastening metal bodies each having a substantially bowl-shaped cross section and having a raised peripheral edge for holding the beads around the circumference, is provided with a flat plate-shaped support portion having a required height at the base end on the connection side of one side,
A locking ring and a pillar-shaped locking ring whose other connecting side base end is pivotally attached to the upper end of the pillar part so as to be freely openable and closable, and whose state when locked to the opening/closing side end of each stopper body is approximately the same height as the pillar part. A locking member consisting of a body is provided between the opposing inner surfaces of the pair of fastener bodies, and the bead has a required width that allows substantially the entire circumferential surface of the bead to be annularly exposed except for the locking member and the strut portion. It is characterized by forming a space for body exposure. [Function] When the bead A is stopped by the stopper main body 1 during use, each concave arc surface 1a of the stopper main body 1 should pinch the opposing surfaces of the peripheral surface of the bead A at the part to be stopped. The bead A can be easily stopped as shown in FIG . To remove the locking member 4, the stopper body 1 can be easily removed from the bead A by opening the opening/closing side end of the stopper main body 1 using the pivot portion 3 at the base end of the connecting side as a fulcrum . can be removed. In addition, when stopping the bead A with the stopper body 1 , by selecting and stopping the bead A at an arbitrary part of the connected bead A', the mounting manner and length of the connected bead A' can be changed from 8th to 8th. 9. It can be used by changing it as shown in the figure. [Example] Figures 1 to 9 show an example of the present invention,
Reference numeral 1 denotes a stopper main body, which is a pair of bodies having a substantially bowl-shaped cross section with an inner surface formed into a concave arc surface 1a and an outer surface formed into a convex arc surface 1b so as to be able to sandwich opposing surfaces of the circumferential surface of the bead A. It consists of 1c is the concave arc surface 1a
2 is a raised peripheral edge of the pair of fastener bodies 1;
A pillar part of the required height provided at the base end of one of the connecting sides,
Reference numeral 3 denotes a pivoting portion at the upper end of the support column, to which the other connecting side proximal end of the stopper main body 1 is pivotally attached. Note that the structure of the pivot portion 3 may be any known structure such as a hinge type, a pivot pin type, or the like. 4 is a locking member provided at the opening/closing side end of the stopper main body 1 ,
It is formed at approximately the same height as the support column 2 at the base end of the connection side. The locking member 4 has a structure in which one side is a locking ring and the other side is a columnar body. B is a bead having a required width that allows approximately the entire circumferential surface of the bead A to be exposed in an annular manner between the opposing inner surfaces of the stopper body 1 when the bead is held, excluding the locking member 4 and the strut portion 2. The exposure space 5 is a bead connecting ring provided in the stopper main body 1, to which a connector 6 at the end of the connecting bead A' is connected.
7 is a three-dimensional pattern formed on the convex arc surface 1b of the stopper main body 1 . [Effects] As explained above, according to the present invention, by being attached to both ends of the bead netcress formed by connecting a large number of beads, and by selectively changing the attachment points to the beads, This is a stopper for a bead necklace that allows the attachment mode and length of the netcle to be arbitrarily changed, and the inner surface is a concave arc surface and the outer surface is a convex arc surface so that opposing surfaces of the beads can be held together. At the proximal end of one connecting side of a pair of fastener bodies, each of which has a substantially bowl-shaped cross-section and is provided with a raised peripheral edge for holding beads around the entire circumference of the mouth edge of the inner concave arc surface. A flat plate-like support section is provided, and the other connecting side base end is pivotally connected to the upper end of the support section so as to be openable and closable, and the state when locked to the opening/closing side end of each of the stopper bodies is A locking member consisting of a locking ring and a columnar body that is approximately the same height as the part is provided between the opposing inner surfaces of the pair of locking metal bodies, and approximately the entire circumference of the bead excluding the locking member and the pillar part is provided. Since the space for exposing the beads is formed with the required width to allow the surface to be exposed in an annular shape, the stopper body is made of a ring body formed by bending a conventional thin metal wire into a ring shape and a thin metal plate. It has superior strength compared to a stopper made of a perforated frame body, and there is no risk of breakage or deformation during use. Since the bead is held by the provided raised peripheral edge, it is possible to securely hold the bead in a stable state, and the outer surface of the bead is held in place by the support portion and the locking member. Since it is designed so that it can be held between the bead holding parts of the metal fitting body with the required width and substantially exposed in an annular manner over almost the entire circumference, the beauty of the bead itself can be greatly emphasized. and
In addition, since the front and back sides of the fasteners are the same shape, there is no need to pay attention to the front and back sides when fastening the fasteners, making it extremely easy to handle. By clamping and attaching the outer surface of the bead at the desired location, the length of the netskure and the way it is attached can be varied to create a variety of decorative styles compared to the conventional one-piece closure. It also has excellent aesthetic effects, such as being able to be used in a variety of ways.
