Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fastener and an accessory having the fastener.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 9, when connecting jewelry, etc., a fastener 12 having elasticity is inserted into the fastener 11 and is fixed by pressing the folded piece 13 of the fastener up and down. It was being done. On the outside of such fasteners, gold plating was applied so as not to be unsightly, and decorations such as the par 8 were applied.

[0003]

[Problems to be solved by the device]

 However, the conventional fasteners for jewelery have the above-mentioned configuration, and thus become large parts, which poses a problem in the overall design of the ornamental product. Therefore, the object of the present invention is to realize a small and discreet fastener, and an accessory having such a fastener.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention relates to a fastener for jewelry or the like, in which a tubular portion, a connecting portion provided at one end of the tubular portion, an opening provided at the other end of the tubular portion, and a tubular portion Pipe member having a hole provided on the side surface of the pipe member, a cylindrical portion having an outer diameter smaller than the inner diameter of the tubular portion of the pipe member, a connecting portion provided at one end of the cylindrical portion, and the other end of the cylindrical portion. A small and inconspicuous fastener was realized by adopting a structure in which the tip of the spring provided on the back is folded back and the insertion part has the spring part forming the key part.

[0005] Further, by embedding the above-mentioned fasteners in jewelry, it is possible to use an accessory that is inconspicuous as a fastener.

[0006]

[Action]

 In the fastener configured as described above, the columnar portion having the spring member is used as the inserting member, and the inserting member is inserted from the opening of the pipe member having the cylindrical portion. Since the tip of the spring member provided on the insertion member projects beyond the inner diameter of the cylindrical portion, when it aligns with the position of the hole provided on the tubular portion of the pipe member, it projects outside from the inner wall of the tubular portion. Then, the key portion at the tip of the protruding spring portion is caught by the hole in the cylindrical portion and is regulated, so that the pipe member and the inserting member are fixed.

[0007] Furthermore, the insertion member is further inserted into the back of the pipe member to release the catch between the key portion and the hole of the tubular portion, and then the insertion member is rotated at an appropriate angle to pull out from the pipe material. The insertion member can be easily removed from the pipe member. Also, by embedding the tubular part of the fastener with such a configuration in jewelry, it is possible to make an accessory having a fastening function.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view of a pipe member according to a first embodiment of the present invention when a penetrating member is inserted, and FIG. 2 is a sectional view when the pipe member and the penetrating member are engaged with each other. FIG. 3 is a top view when the pipe member and the insertion member are engaged with each other. FIG. 4 is a sectional view when the key of the spring portion of the insertion member is removed from the hole of the pipe member.

In FIG. 1, a hollow cylindrical portion 1 is provided with a connecting portion 3a for connecting with jewelry at one end and an opening 4 at the other end. The tubular portion 1 is formed of a pipe material 1a having a hole portion 6 on its side surface. On the other hand, similarly, the insertion member 2 provided with the connecting portion 3b for jewelry at one end has a cylindrical portion 2a having a diameter smaller than the inner diameter of the pipe material to be inserted into the pipe material 1a.

A spring member 5 is fixed to the columnar portion 2a, the tip of the spring member 5 has a folded portion 5a protruding from the inner diameter of the pipe material 1a, and the tip of the folded portion 5a forms a key portion 5b. .. By inserting the insertion member 2 into the opening 4 of the pipe material 1 from the folded portion 5a at the tip, the folded portion 5a bends smaller than the inner diameter of the pipe material 1a due to the elasticity of the spring, and pushes the pipe material from the inside to move forward.

In FIG. 2 and FIG. 3, when the tip key portion 5b of the folded-back portion 5a comes to the position of the hole portion 6 of the pipe material, it protrudes from the hole portion 6 to the outside of the pipe material, and at the hook portion 6a of the hole portion. Get caught. Thus, the insertion member 2 is fixed to the tubular portion 1 as shown in FIGS. When the columnar portion 2a is further pushed in the direction of the arrow as shown in FIG. 4, the hook portion 5b at the tip of the folded portion 5a is elastically returned to the inside of the pipe material 1a and is disengaged from the hook portion 6a.

Further, when the columnar portion 2a is rotated so that the hook portion 5b is located at a position where the inner wall of the pipe material 1a removed from the hole portion 6 is held, and the insertion member 2 is pulled out, it can be removed from the tubular portion 1. As in the above configuration, the smaller the width of the folded portion of the spring member, the thinner the pipe material 1a can be made, and the pipe material 1a can be used as an inconspicuous small fastener.

FIG. 5 is a second embodiment of the present invention in which the fastener of the present invention is embedded in jewelry. As shown in FIG. 5, a jewelry, for example, a pearl 8 is provided with a hole 8a having a diameter larger than that of the pipe material 1a, and the pipe material 1a is inserted into and fixed to the hole 8a of the pearl 8. become. At this time, the connecting portion 3 a is outside the pearl 8. By inserting and fixing the insertion member 2a into the above-mentioned ornament, the joint with the jewelry such as the pearl 8 connected to the ends of the connecting portions 3a and 3b can be connected inconspicuously.

As a third embodiment of the present invention, as shown in FIG. 6, a connecting portion 3a is formed on the right side of the end of the tubular portion 1, and a connecting portion 3b is formed on the right side of the end of the insertion member 2. . By inserting and fixing the above-mentioned insertion member 2 into the pearl 8 to which the above-mentioned cylindrical portion 1 is inserted and fixed, the jewelry or chain 9 is connected by the distance between the connecting portions 3a and 3b. It Such ornaments can be widely applied to apparel such as necklaces, bracelets and anklets.

FIG. 7 shows a fourth embodiment of the fastener of the present invention. The connecting portions 3a and 3b can be formed in the main body of the tubular portion 1 and the inserting member 2, respectively, and can be used as a less noticeable fastener. FIG. 8 shows a fifth embodiment of the fastener of the present invention. Two spring members 5 at the tip of the columnar portion 2a are provided, and folding portions 5a and 5b are provided at each of them. The hooks 5a and 5b are provided at the ends of the folded portions, respectively, and are configured to be hooked in the holes 6 provided on the side surface of the pipe material 1a, respectively. By having a plurality of hooks, the fixing strength is increased. ..

[0016]

[Effect of the device]

 According to the present invention, as described above, the insertion member having the connecting portion and the spring member is inserted into the tubular portion having the connecting portion, and the hook portion at the tip of the spring member is hooked and fixed to the hole provided in the pipe material. By doing so, it is possible to manufacture a small and unobtrusive fastener.

In particular, by manufacturing as a decorative article having a fastener, the restriction that the conventional fastener is large and conspicuous is eliminated, so that the design can be freely made in various fields and the variation can be expanded.
