Japanese Patent No. 3848654

  In the fasteners for the body chain as described above, since the guide cylinder member of the push part of the button structure is made by casting, the weight increases and the body chain itself becomes heavier and feels comfortable to wear. In addition, there is a problem that the cost is increased because the amount of bullion used increases. Furthermore, when the pressing member has a circular shape, the receiving member rotates in the hollow member, and when the chain main body is received in the stopper, the chain insertion passage of the pressing member extends from the chain hole of the hollow member. There was an inconvenience that it was not exposed to the outside. In addition, it is not easy to form the guide member with high accuracy so that the pressing member is accommodated in the hollow member and the pressing member is smoothly projected and retracted. For this reason, there has been a problem that it takes a lot of labor to process the fasteners, and efficient production cannot be performed in a short period of time.

  The present invention has been made in view of the above problems, and provides a fastener for a body chain that can be freely molded into various sizes and shapes and can be efficiently manufactured at low cost. is there.

The invention according to claim 1 of the present invention includes a hollow member, a pressing member, and a guide member, and the hollow member accommodates the pressing member and the guide member in a hollow interior surrounded by a peripheral wall. Each of the hollow members has a housing part, where the peripheral walls of the hollow member face each other are provided with chain holes that lead to the housing part, and the upper part of the peripheral wall has an intrusion hole. It has a pressed portion and a chain insertion passage, and the pressed portion protrudes and protrudes from the hollow hole of the hollow member, and the chain insertion passage is each chain hole of the hollow member when the pressing member sinks. The guide member is formed of a leaf spring, and is wound around a cylindrical shape so as to surround the outer periphery of the pressing member, and guides the pressing member in a slidable state to the intrusion hole. It has an opening part connected to each of the chain insertion passage of the member and each chain hole of the hollow member And wherein the door.

  According to the second aspect of the present invention, the guide member is thinly wound into a cylindrical shape and is inserted into the accommodating portion from the recess / intrusion hole of the hollow member, and is swelled in the accommodating portion by the elastic return of the leaf spring and is formed on the inner wall of the hollow member. It is abutted and positioned.

  The invention according to claim 3 of the present invention is characterized in that the intrusion hole and the pressing member of the hollow member have an elliptical shape.

  According to the first aspect of the present invention, since the guide member is formed by rounding the leaf spring into a cylindrical shape, the degree of rounding of the guide member is adjusted to match the size of the opening of the hollow member. A hollow part can be inserted. As a result, after the guide member is inserted into the hollow portion of the hollow member, the guide member that has been rolled up into a cylindrical shape is loosened and is elastically pressed against the inner peripheral side of the peripheral wall of the guide member. Positioned. Therefore, when the guide member is inserted into the hollow portion of the hollow member, the guide member hits the inner peripheral side of the hollow portion, so that the step of positioning in accordance with the opening of the hollow portion is not necessary. In addition, since the guide member is formed by a leaf spring, the diameter of the cylinder can be changed freely by its elastic deformation, so it can be used for hollow parts of various sizes and shapes with only a small number of guide members. Can be made. In addition, since the guide member has a structure in which the leaf spring is rounded into a cylindrical shape, the weight is very light compared to a conventional one formed by casting or the like, and it is a valuable metal used for manufacturing fasteners. Therefore, it is possible to suppress the increase in the weight and cost of the applied chain.

  According to invention of Claim 2 of this invention, since a guide member is what rounded a leaf | plate spring, a guide member can be rounded so that it may become narrower than an intrusion hole. As a result, regardless of the size and shape of the hollow hole of the hollow member, the guide member can be rolled and placed in the housing portion of the hollow member, and the guide member can be elastically restored in the housing portion. By doing so, the inner wall portion of the peripheral wall of the accommodating portion is pressed, so that the guide member can be easily positioned in the hollow member. Furthermore, since the guide member can be appropriately deformed according to the diameter and shape of the outer periphery of the pressing member, it is possible to provide a fastener for a decorative chain that is rich in decoration.

  According to the invention described in claim 3 of the present invention, the outer shape of the hollow member and the pressing member are made elliptical so that the pressing member does not rotate at the hollow portion of the hollow member or the inner peripheral portion of the guide member. . From this, the chain insertion passage of the pressing member is always arranged so as to face the opening of the guide member, so that the chain body can be easily passed when passing through the chain hole of the hollow part. It can provide a fastener for a jewelry chain that is easy to wear.

Below, the fastener for the jewelry chain by this implementation is demonstrated based on drawing.
As shown in FIGS. 1 and 2, the fastener 1 for a body chain according to this embodiment includes a hollow member 2, a pressing member 3, and a guide member 4. Moreover, said stopper 1 makes the chain | strand main body 11 endless by inserting the chain | strand main body 11 which consists of noble metal raw materials, such as gold | metal | money, silver, and platinum, and hold | maintaining the outer peripheral part of the chain | strand main body 11. is there. In addition, as an example, a ball chain 11 is used for the chain body 11 constituting the body chain according to the present embodiment.

  In the present embodiment, the hollow member 2 has a hollow structure surrounded by a substantially spherical peripheral wall. The hollow member 2 has an opening at the top to provide an in / out hole 5, and chain holes 6a at two locations facing the peripheral wall. , 6b are provided. As shown in FIGS. 1 and 2, the pressing member 3 has a cylindrical shape having a rounded pressed portion 7 for applying a finger to the upper portion. In addition, a receiving member 13 having a plate shape for receiving a coil spring (biasing member) 8, which will be described later, is disposed at the lower end of the pressing member 3. Further, notches 12a and 12b are provided at two locations facing the peripheral wall of the pressing member 3, and a chain insertion passage 12 is formed by the notches 12a and 12b. As shown in FIGS. 3A to 3D, the guide member 4 uses a leaf spring having a long strip shape and a rectangular shape on one side. Further, the central portion of the leaf spring is penetrated, and an opening 9 for inserting the ball chain 11 is provided there. The guide member 4 is formed into a cylindrical shape by winding the above-described leaf spring into a cylindrical shape, and the diameter of the cylinder can be arbitrarily changed depending on the degree of winding.

By each of the above-described constituent members, the stopper for the accessory chain according to the present embodiment is a guide member that is rounded to the housing portion S of the hollow member 2 as shown in FIGS. 1, 2, 4 (a) and 4 (b). 4 is inserted. Further, the coil spring 8 is fixed to the inner peripheral portion of the hollow member 2, and the coil spring 8 is disposed on the bottom portion of the guide member 4. Then, the receiving member 13 of the pressing member 3 is placed on the coil spring 8 so that the pressing member 3 is always urged upward by the coil spring 8, and the outer peripheral portion of the pressing member 3 is placed inside the hollow member 2. Lock to the perimeter. Thereby, the pressing member 3 is arranged so that the pressed portion 7 can be protruded and retracted from the retracting hole 5 of the hollow member 2. At this time, if the guide member 4 is rounded into a cylindrical shape, the opening 9 occupies a wide range of the peripheral wall of the cylinder. When the guide member 4 is accommodated in the accommodating portion S of the hollow member 2, the two through holes 6 a and 6 b facing the peripheral wall of the hollow member 2 and the opening 9 of the guide member 4 coincide with each other. A space through which the chain body 11 is inserted is formed by the chain holes 6a and 6b and the opening 9 of the guide member 4. Further, when the pressing member 3 is slidably inserted up and down on the inner peripheral side of the guide member 4, the notches 12 a and 12 b of the chain insertion passage 12 of the pressing member 3 are elliptical when the pressing member 3 is viewed in plan view. By making the shape, the pressing member 3 does not rotate along the inner peripheral portion of the peripheral wall of the guide member 4, thereby positioning the opening direction with respect to the opening 9 of the guide member 4.
Thereby, the entrance and the exit of the chain insertion passage 12 of the pressing member 3 are aligned with the opening 9 of the guide member 4 and the chain holes 6a and 6b of the hollow member 2 only by inserting the guide members 4 in the same direction. Moreover, even if the guide member 4 appears and disappears, the position does not shift.

Next, a procedure for attaching the ball chain 11 to the stopper according to the present embodiment described above and an operating state of the stopper will be described below.
When the ball chain 11 is held by the stopper 1, as shown in FIGS. 5 (a) and 5 (b), first, the pressing member 3 of the stopper 1 is pushed in, so that the pressing member 3 becomes the urging force of the coil spring 8. Push and push down. At this time, the entrance of the insertion passage 12 of the pressing member 3 communicates with the opening 9 of the guide member 4, and the insertion passage 12 and the opening of the guide member 4 also from the chain holes 6 a and 6 b of the hollow member 2. 9 is exposed. Then, the ball chain 11 is inserted from one chain hole 6 a of the hollow member 2 of the stopper 1, and the inserted ball chain 11 is further pushed into the opening 9 of the guide member 4, the chain insertion passage 12 of the pressing member 3, By passing, the ball chain 11 is extracted from the other chain passage hole 6b of the hollow member 2 from the insertion tip side. Then, as shown in FIGS. 5C and 5D, when the finger is released from the pressed portion 7, the pressing member 3 is lifted by the biasing force of the coil spring 8, and the upper end of the opening 9 of the receiving member 13 and the guide member 4. The ball chain 11 is held between the two parts. Further, when adjusting the position where the ball chain 11 of the stopper 1 is held, if the pressed portion of the pressing member 3 is pushed in, the holding state of the stopper 1 and the ball chain 11 is released. The ball chain 11 can be positioned at any location. The upper and lower end edges of the opening of the guide member 4 are substantially linear, and the chain insertion passage 12 of the pressing member 3 and the inlet and outlet are also facing each other. As a result, the contact between the ball chain 11 and the stopper 1 when held by the stopper 1 becomes small, so that the stopper 1 can be smoothly attached to and detached from the ball chain 11 and the outer peripheral portion has many irregularities. Even with the chain 11, the stopper 1 can slide smoothly.

  The fastener 1 for an accessory chain of the present invention can be used as a chain body 11 or 21 to be held, in addition to the above-described ball chain 11, Kihei 21 or azuki bean. As shown in FIG. 7, the stopper 1 holds a chain body 21 in which a large number of pieces in a ring shape called “Kihei 21” or “Azuki” are connected in series. Even in such a case, the chain main body 21 has its longitudinal end portion inserted through the chain holes 6a and 6b of the hollow member 2, and the pressing member 3 is further pressed with a finger so that the chain insertion passage 12 of the pressing member 3 is inserted. By opening the opening 9 of the guide member 4, the chain body 21 can be communicated with the stopper 1. Further, when the finger is released from the pressed portion 7 of the pressing member 3, the pressing member 3 moves upward by the biasing force of the coil spring 8. At this time, the chain body 21 is held by the stopper 1 by sandwiching the outer periphery of the chain body 11 between the upper surface of the receiving member 13 of the pressing member 3 and the upper inner periphery of the opening 9 of the guide member 4. .

  The stopper 1 for a body chain according to the present invention is such that the guide member 4 is rounded into a cylindrical shape, and the guide member 4 that is rounded against elasticity is elastic when the thinly rounded cylindrical guide member 4 is elastically restored. Is loosened and the inner peripheral surface of the peripheral wall of the hollow member 2 is pressed by the elasticity of the leaf spring, so long as the guide member 4 can be disposed in a positioned state. In addition, as for the shape of the pressed portion 7 of the pressing member 3 and the shape of the protruding and retracting hole 5 of the hollow member 2, since the guide member 4 is formed by rounding a leaf spring, the shape can be freely changed. Any shape other than a perfect circle may be a polygonal shape such as a hexagonal shape or an octagonal shape, or any shape that does not cause the pressing member 3 to idle along the inner peripheral portion of the guide member 4. The guide member 4 expands in the accommodating portion S of the hollow member 2 to form a peripheral wall surrounding the outer periphery of the pressing member 3, but both sides of the peripheral wall of the guide member 4 as long as the pressing member 3 does not detach from the guide member 4. There may be a state in which there is a slight gap between the end portions 4a and 4b, or both end portions of the peripheral wall may overlap as long as the sliding of the pressing member 3 is not hindered. In addition to the coil spring, the urging member 8 may be a leaf spring or the like as long as it is attached to the hollow member 2 and applies an urging force to the pressing member 3.
