Summary of the Invention

Problems to be Solved by the Invention

[0004] In a molded article formed by injection molding, distortion, depression, so-called sink marks may occur due to molding shrinkage when the molten resin cools and solidifies in the mold. In particular, in a member having a portion protruding from the main body portion, sink marks are likely to occur and appearance defects are likely to be caused, so countermeasures against sink marks are required.

[0005] On the other hand, since a fastening member such as the clip described in Patent Document 1 is used by being fastened to an object to be attached, it is desired that the outer shape, size, etc. do not hinder the handleability.

[0006] Therefore, an object of the present invention is to achieve both prevention of appearance defects and improvement of handleability in a fastening member attached to an object to be attached.

Means for Solving the Problems

[0007] According to an aspect of the present invention, there is provided a fastening member including a main body portion having a plurality of convex portions and a fastening portion having a plurality of hole portions, the fastening member being fastened to an object to be attached by inserting the plurality of convex portions through the object to be attached and fitting the plurality of convex portions into the plurality of hole portions. The main body portion includes a plurality of concave portions formed in regions corresponding to the plurality of convex portions on the opposite surface of the surface on which the plurality of convex portions are formed, a housing portion formed between two of the plurality of concave portions and accommodating an electronic device, and a lid portion covering the housing portion so as to be flush with the opposite surface.

Advantages of the Invention

[0008] According to an aspect of the present invention, in the main body portion, concave portions are formed in regions corresponding to the plurality of convex portions on the opposite surface of the surface on which the plurality of convex portions are formed. Therefore, it is difficult for sink marks to occur on the back side of the convex portions. Thereby, it is possible to prevent appearance defects of the fastening member attached to the object to be attached.

[0009] Further, since the housing portion for the electronic device is provided between the concave portions, the fastening member can be miniaturized. Furthermore, since the lid portion is configured to cover the housing portion so as to be flush with the surface on which the concave portions are formed, it is possible to prevent other articles from being damaged even when the surface on which the concave portions are formed comes into contact or abuts against other articles. Thereby, the handleability of the fastening member can be improved.

[0010] Therefore, according to an aspect of the present invention, in the fastening member attached to the object to be attached, it is possible to achieve both prevention of appearance defects and improvement of handleability.

The method of using the fastening member includes housing the electronic device in the housing portion, covering the housing portion with a lid portion so as to be flush with the opposite surface, inserting the plurality of convex portions through the object to be attached, fitting the plurality of convex portions into the plurality of hole portions, and fastening the object to be attached.

[0036] According to the 11th aspect of a certain aspect of the present invention, an electronic device can be housed in a housing portion, covered with a lid portion, and fastened to an object to be attached.

[0037] [Description of the fastening member] Hereinafter, the fastening member 1 according to an embodiment of the present invention will be described.

[0038] FIG. 1 is a perspective view of the fastening member 1 as viewed from one surface side, and FIG. 2 is a perspective view of the fastening member 1 as viewed from the opposite surface side of one surface.

[0039] FIG. 3 is a plan view of the fastening member 1 in a fastened state as viewed from the front surface side. FIG. 4 is a plan view of the fastening member 1 in a fastened state as viewed from the back surface side. FIG. 5 is a cross-sectional view taken along line V-V of FIG. 4.

[0040] The fastening member 1 according to the present embodiment includes a main body portion 2 and a fastening portion 3. FIG. 1 shows a perspective view of the fastening member 1 in a pre-fastening state in which the main body portion 2 and the fastening portion 3 are fitted together, as viewed from the surface 2A and the surface 3A sides that face each other in the fastened state.

[0041] Moreover, FIG. 2 shows a perspective view of the fastening member 1 in a pre-fastening state, as viewed from the surface side constituting the front and back surfaces of the fastening member 1 in the fastened state.

[0042] In this embodiment, the surface of the fastening member 1 is the surface 3B opposite to the surface 3A of the fastening portion 3, and the back surface of the fastening member 1 is the surface 2B opposite to the surface 2A of the main body portion 2.

[0043] As shown in FIG. 1, the main body portion 2 has two convex portions 21 and 22 protruding in the vertical direction from one surface 2A of the main body portion 2.

[0044] The convex portion 21 includes a shaft portion 211 and a head portion 212 formed larger than the outer diameter of the shaft portion 211. The convex portion 21 also includes a plurality of locking claws 213 on the side surface of the shaft portion 211. The locking claws 213 have an inclined surface that inclines along the inclined surface of the head portion 212.

[0045] Similar to the convex portion 21, the convex portion 22 also includes a shaft portion 221, a head portion 222, and locking claws 223.

[0046] As shown in FIG. 2, the main body portion 2 has a concave portion 23 in a region corresponding to the convex portion 21 and a concave portion 24 in a region corresponding to the convex portion 22 on the surface 2B which is the opposite surface of one surface 2A of the main body portion 2.

[0047] The main body portion 2 also has a housing portion 25 for housing the electronic device 5 between the two concave portions 23 and 24. The main body portion 2 also has a lid portion 26 for covering the housing portion 25. The lid portion 26 and the main body portion 2 are connected to each other by a first hinge portion 27 at the end of the housing portion 25.

[0048] FIG. 1 shows a state where the closed first hinge portion 27 can be seen through the gap of the main body portion 2. FIG. 2 schematically shows a state where the lid portion 26 is opened and the electronic device 5 housed in the housing portion 25 is taken out.

[0049] In this embodiment, the electronic device 5 is, as an example, a module including an antenna pattern and an IC chip corresponding to RFID (Radio Frequency Identification) technology for transmitting and receiving information by non-contact communication. Further, the electronic device 5 may include a memory with a predetermined capacity.

[0050] In this embodiment, applicable non-contact communications include wireless communication by electromagnetic induction (Near Field Communication: NFC) using the LF band (frequency 135 KHz or less), the HF band (3 MHz to 30 MHz, particularly a specific frequency band of 13.56 MHz), etc., and wireless communication by radio waves using the UHF band (frequency 860 - 960 MHz), the microwave band (frequency 2.45 GHz), etc.

[0051] The lid portion 26 is provided with locking claws 261 for locking the lid portion 26 to the main body portion 2 in a state of covering the accommodating portion 25.

[0052] The accommodating portion 25 has a shape in which the lid portion 26 can fit, and has a recessed portion 251 and an electronic device accommodating portion 252.

[0053] The recessed portion 251 is formed to be lower by the thickness of the lid portion 26 from the surface 2B. Further, the electronic device accommodating portion 252 is formed to be lower by the thickness of the electronic device 5 from the recessed portion 251. Further, a locking hole 253 for locking the locking claws 261 provided on the lid portion 26 is formed in the recessed portion 251.

[0054] Thereby, as shown by the arrow F2 in FIG. 2, the lid portion 26 can move with the first hinge portion 27 as a base point and cover the accommodating portion 25. At this time, as shown in FIG. 5, the lid portion 26 is flush with the surface 2B in which the recesses 23 and 24 are formed.

[0055] Further, the lid portion 26 can be held in a closed state by being locked to the recessed portion 251 by the locking claws 261 and the locking holes 253 in a state of covering the accommodating portion 25.

[0056] The fastening part 3 has two hole parts 31 and 32. When the main body part 2 and the fastening part 3 are overlapped so that the surface 2A of the main body part 2 and the surface 3A of the fastening part 3 face each other, the hole part 31 is formed at a position corresponding to the convex part 21. The hole part 32 is formed at a position corresponding to the convex part 22.

[0057] In addition, in the present embodiment, both the hole parts 31 and 32 are formed so as to penetrate the fastening part 3.

[0058] The surface 3B, which is the opposite surface of the surface 3A in the fastening part 3, has a curved surface shape that is convex outward.

[0059] The fastening part 3 has an annular locking valve body 312 that extends from the inner wall of the hole part 31 toward the center of the hole, and a slit 311 is formed in part of it. The locking valve body 312 has a smaller diameter than the diameter of the hole part 31 and an inner diameter that is slightly larger than the outer diameter of the shaft part 211 described above. The locking valve body 312 is configured to expand in diameter as the slit 311 expands.

[0060] Similarly, the hole part 32 has an annular locking valve body 322 in which a slit 321 is formed.

[0061] As shown in FIGS. 1 and 2, the above-described main body part 2 and fastening part 3 are connected to each other by a second hinge part 4 at one edge part.

[0062] Thereby, as shown by the arrow F1 in FIG. 1, the main body part 2 and the fastening part 3 can be overlapped so that one surface 2A of the main body part 2 and one surface 3A of the fastening part 3 face each other with the second hinge part 4 as a base point.

[0063] When the main body part 2 and the fastening part 3 are overlapped, the head 212 of the convex part 21 abuts against the locking valve body 312 formed in the hole part 31. When the head 212 is pushed in, due to the flexibility of the resin, which is the material of the fastening member 1, the interval between the slits 311 expands, and while expanding the diameter of the locking valve body 312, it passes through the locking valve body 312.

[0064] Following the head portion 212, the locking claw 213 also passes through the locking valve body 312 in the same manner. After the locking claw 213 passes through, the locking valve body 312 reduces its diameter to the original diameter size. As a result, the inner edge of the locking valve body 312 abuts against the outer wall of the shaft portion 211. The locking valve body 312 cannot be removed in the direction opposite to the pushing direction because the locking claw 213 obstructs it.

[0065] As a result, the convex portions 21, 22 can be inserted into the object to be attached and fitted into the hole portions 31, 32, and the fastening member 1 can be fastened to the object to be attached.

[0066] In the fastened state where the main body portion 2 and the fastening portion 3 are fitted together, as shown in FIG. 3, the first hinge portion 27 is formed so as to fit within the widths of the main body portion 2 and the fastening portion 3 in a side view seen from the direction (arrow W in FIG. 3) along the line connecting the two convex portions 21, 22.

[0067] Also, in the fastened state, the second hinge portion 4 is configured in a round shape that forms a series of curved surfaces continuous with the outer shapes of the main body portion 2 and the fastening portion 3.

[0068] The above-described main body portion 2, fastening portion 3, lid portion 26, first hinge portion 27, and second hinge portion 4 can be formed by integral molding using a mold. As a molding method, injection molding can be applied.

[0069] [Effect of the fastening member] According to the fastening member 1 according to the embodiment of the present invention, recesses 23, 24 are formed in regions corresponding to the convex portions 21, 22 on the surface 2B opposite to the surface 2A on which the convex portions 21, 22 are formed, on the main body portion 2.

[0070] Therefore, when the fastening member 1 is formed by injection molding, when the molten resin cools and solidifies in the mold, the recesses 23, 24 on the back side of the convex portions 21, 22 can make it difficult to generate sink marks. As a result, the fastening member 1 according to the present embodiment does not cause appearance defects.

[0071] In the fastening member 1, by disposing the accommodating portion 25 between the recessed portions 23 and 24, that is, between the convex portions 21 and 22 serving as fastening locations, for example, in a direction intersecting the direction in which the accommodating portion of the electronic device connects the fastening locations, the fastening member 1 can be miniaturized as compared with a structure provided side by side with the fastening locations. Therefore, the handling property of the fastening member 1 according to the present embodiment is enhanced.

[0072] Further, the accommodating portion 25 has a shape in which the lid portion 26 can be accommodated, and has a recessed portion 251 in which the lid portion 26 can be accommodated and an electronic device accommodating portion 252 in which the electronic device 5 can be accommodated. Thereby, in the closed state, the lid portion 26 is flush with the surface 2B on which the recessed portions 23 and 24 are formed.

[0073] Therefore, even if the surface 2B on which the recessed portions 23 and 24 of the fastening member 1 come into contact with or abut against other articles, it is possible to prevent the lid portion 26 from damaging other articles. Thereby, the handling property of the fastening member 1 can be improved.

[0074] Therefore, according to the fastening member 1, it is possible to achieve both prevention of appearance defects and improvement of handling property.

[0075] Also, in the fastening member 1, the surface 3B of the fastening portion 3 has a convex curved surface shape. Therefore, even when the fastening member 1 comes into contact with or abuts against other articles in a state where the fastening member 1 is fastened to the object to be attached, it is possible to prevent the fastening member 1 from damaging other articles.

[0076] In the fastening member 1, in the fastened state where the main body portion 2 and the fastening portion 3 are fitted together, the first hinge portion 27 is formed so as to fit within the widths of the main body portion 2 and the fastening portion 3 in a side view as viewed from the arrow W.

[0077] Therefore, the protrusion of the first hinge portion 27 can be reduced, and even when the fastening member 1 comes into contact with or abuts against other articles in a state where the fastening member 1 is fastened to the object to be attached, it is possible to prevent the fastening member 1 from damaging other articles.

[0078] Further, in the fastening member 1, in the fastened state where the main body portion 2 and the fastening portion 3 are fitted together, the second hinge portion 4 is configured in a round shape that forms a series of curved surfaces continuous with the outer shapes of the main body portion 2 and the fastening portion 3. Therefore, even when the fastening member 1 comes into contact or abuts against other articles in the state where the fastening member 1 is fastened to the object to be attached, it is possible to prevent the second hinge portion 4 from damaging other articles.

[0079] The fastening member 1 is a module in which the built-in electronic device 5 is integrally formed with an IC chip and an antenna connected to the IC chip. Thereby, the fastening member 1 can be miniaturized.

[0080] Also, an electronic device corresponding to wireless communication by electromagnetic induction or an electronic device corresponding to wireless communication by radio waves can be applied. Thereby, using the fastening member 1, a wireless communication function can be added to the object to be attached.

[0081] [Usage method of the fastening member] The usage method of the fastening member 1 described with reference to FIGS. 1 to 5 is as follows. That is, the electronic device 5 is housed in the housing portion 25, and the housing portion 25 is covered with the lid portion 26 so as to be flush with the surface 2B. Subsequently, the convex portions 21, 22 are inserted into the object to be attached, and the convex portions 21, 22 are fitted into the hole portions 31, 32 to fasten the object to be attached.

[0082] According to the fastening member 1 according to the present embodiment, as an example, the electronic device 5 can be housed and fastened to the object to be attached. Therefore, even when it is difficult to mount the electronic device 5 on the completed article, by using the fastening member 1, the electronic device 5 can be fastened to the article, and the article can be given the same function as when the electronic device 5 is mounted.

[0083] [Explanation of the object to be attached] In the present embodiment, the object to be attached includes those to which the fastening member 1 can be fastened, such as clothes, bags, containers, documents, books, strings, cables, straps, papers, tags, etc. As an example, the case where the object to be attached is a wristband as an example of a tag will be described.

[0084] <Wristband> FIG. 6 is a plan view for explaining the wristband 100.

[0085] As shown in FIG. 6, the wristband 100 has an elongated shape and is used by being wound around the user's wrist.

[0086] The wristband 100 includes a band portion 101A on one end portion 100A side and a band portion 101B on the other end portion 100B side. Further, the wristband 100 includes a printing portion 102 between the band portion 101A and the band portion 101B.

[0087] A plurality of apertures 103 penetrating the wristband 100 are formed in the band portions 101A and 101B. The positions of the apertures 103 in the width direction orthogonal to the longitudinal direction of the wristband 100 are formed to correspond to the length from the boundary portion 41 between the main body portion 2 and the fastening portion 3 to the convex portions 21 and 22 in the second hinge portion 4 of the fastening member 1.

[0088] Further, the intervals between the apertures 103 are formed to match the intervals between the convex portions 21 and 22 and the hole portions 31 and 32.

[0089] Although not shown, the wristband 100 includes a front surface base material that is the front surface of the wristband 100 and a back surface base material that is the back surface.

[0090] As the front surface base material, a single resin film such as polyvinyl chloride, polyethylene terephthalate, polypropylene, polyethylene, polyethylene naphthalate, or a multilayer film formed by laminating a plurality of these resin films can be used.

[0091] In addition to the resin film base material, paper base materials such as cardboard, fine paper, medium paper, or coated paper obtained by appropriately forming a coating layer on these can be used.

[0092] In the present embodiment, a thermosensitive coloring layer is provided on the surface base material of the wristband 100. The thermosensitive coloring layer is formed of a material that develops color by the heat generation scanning of a thermal head of a printer (not shown).

[0093] The back surface base material constitutes the back surface of the wristband 100 and is a base material that comes into contact with human skin. As an example, surface processing such as embossing is performed on the back surface base material. Thereby, air permeability can be ensured between the human skin. Further, the embossing can impart cushioning properties to the back surface base material and make the feel soft.

[0094] FIG. 7 is a schematic diagram for explaining a state in which the ends of the wristband 100 are overlapped and fastened using the fastening member 1.

[0095] As shown in FIG. 7, the above-described wristband 100 can adjust the ring diameter according to the size of the user's wrist by overlapping two through-holes 103 formed in one band portion 101A and any two adjacent through-holes 103 among a plurality of through-holes 103 formed in the other band portion 101B.

[0096] [Effect by Application to Wristband] The fastening member 1 according to the present embodiment can be miniaturized and can prevent other articles that come into contact with or abut against the fastening member 1 from being damaged. Therefore, it can be suitably used for fastening the wristband 100 that is used in contact with human skin.

[0097] The position of the through-hole 103 in the width direction of the wristband 100 is formed so as to correspond to the length from the boundary portion 41 between the main body portion 2 and the fastening portion 3 to the convex portions 21 and 22 in the second hinge portion 4 in the fastening member 1. Further, the interval between the through-holes 103 is formed in accordance with the intervals of the convex portions 21 and 22 and the holes 31 and 32.

[0098] Therefore, when the convex portions 21 and 22 are inserted into the opening 103 with the opening 103 formed in the band portion 101A and the band portion 101B being overlapped, the side edges of the overlapped band portions 101A and 101B abut on the boundary portion 41 between the main body portion 2 and the fastening portion 3 in the second hinge portion 4.

[0099] Thereby, the side edges of the band portion 101A and the band portion 101B that are wound and overlapped in a ring shape can be aligned. Therefore, the wristband 100 after being wound does not have a distorted shape, and the wearing feeling for the user can be improved.

[0100] Further, the fastening member 1 is fitted to the wristband 100 such that the surface 2B of the main body portion 2 of the fastening member 1 becomes a contact surface that contacts the user's skin, and the surface 3B of the fastening portion 3 faces outward.

[0101] Thereby, on the surface 2B to which the lid portion 26 is attached, since the lid portion 26 is flush with the surface 2B, it is possible to prevent giving a sense of discomfort to the user even when contacting the user's skin.

[0102] Further, since the surface 3B of the fastening portion 3 having a convex curved surface shape in the fastening member 1 faces outward, even if the fastening member 1 fastened to the wristband 100 wound around the user's wrist contacts or abuts on other articles, it is possible to prevent damaging other articles.

[0103] [Modification Example] FIG. 8 is a perspective view of the fastening member 10 as a modification example of the present embodiment as viewed from the opposite side of one surface.
