Description

Technical Field

[0001] The present invention relates to an attachment structure for a fastening pin such as a safety pin, and a batch having such a structure. More specifically, the present invention relates to an attachment structure for a fastening pin that attaches a fastening pin with two locking portions having two openings that open in different directions, and a batch having such a structure.

Background Art

[0002] Conventionally, various structures have been proposed as attachment structures for fastening pins such as safety pins. For example, in the attachment structure for a fastening pin described in Patent Document 1, an inverted U-shaped pin holder is formed on the back plate of a batch. The pin holder has an insertion gap. By pushing the wire portion of the safety pin corresponding to the fastening pin into the insertion gap, the safety pin is attached to the back plate. Further, in the attachment structure for a fastening pin described in Patent Document 2, a locking portion is formed on the surface of a substrate of a connecting means. By inserting a mounting shaft formed on the back surface of the substrate into a mounting hole formed in the back cover of the batch, the substrate of the connecting means is connected to the back cover of the batch. The locking portion has an insertion gap into which the wire portion of the fastening pin is inserted, similar to the pin holder described in Patent Document 1.

[0003] Further, Patent Document 1 describes a structure in which two pin holding rings are formed on the back plate of a batch. Each ring of the two pin holding rings has an insertion cut. By pushing the wire portion of the safety pin into the two insertion cuts, the safety pin is attached to the back plate. The two insertion cuts are arranged so as to open on the same side, for example, the lower side, of the two pin holding rings.

Patent Document 2

[0005] In the fastening pin mounting structures described in Patent Documents 1 and 2, the insertion gap of the pin holder and the like is formed to open in a predetermined direction, for example, downward. Also, the two insertion notches of the two pin retaining rings described in Patent Document 1 are formed to open in the same direction, for example, downward. In order to prevent the fastening pin from falling out of the pin holder or pin retaining ring, it is necessary to have a configuration that narrows the insertion gap or a configuration that makes it difficult for elastic deformation of the insertion notches to occur. However, if such a configuration to prevent falling out is adopted, in the case of manual work by an operator to attach the fastening pin to the pin holder or pin retaining ring, it will be necessary to apply a large insertion force to the fastening pin, which may reduce the efficiency of the fastening pin mounting process. Alternatively, even in the case of automated assembly by machine, fine adjustment of the insertion force applied to the fastening pin will be necessary in advance, which may reduce the efficiency of the fastening pin mounting process.

[0006] Therefore, the present invention has been made in view of the above circumstances, and aims to provide a fastening pin mounting structure for a batch that reduces the likelihood of the fastening pin falling off the back surface or connecting member, and facilitates the fastening pin mounting process, and a batch equipped with the same structure. [Means for solving the problem]

[0009] In embodiments of the present invention, the fastening pin may be formed from a wire-like material, such as a safety pin, or it may be constructed by assembling a plurality of plate-like elongated members with a coil spring, such as a tie clip.

[0010] The embodiments of the present invention only need to include at least a first locking portion and a second locking portion arranged on the back surface or the connecting member, and it is not necessary to include a fastening pin as an essential component.

[0011] In aspects of the present invention, a gap may be left between the first locking portion and the second locking portion, as long as a portion of the fastening pin can be inserted from outside the first locking portion and the second locking portion to the first opening and the second opening, or a gap may be formed between the continuously formed first locking portion and the second locking portion that can be opened by elastic deformation.

[0012] In embodiments of the present invention, the elastically deformable opening portion may be positioned only in a portion of each of the first and second openings, or it may be positioned across the entire opening region of each opening.

[0014] Generally, when a fastening pin is attached to the back surface or connecting member, the size of the fastening pin is determined to match the size of the back surface or connecting member so that the fastening pin does not protrude significantly from the back surface or connecting member. The wire diameter of the mounting wire portion is determined according to the size of the fastening pin. In this specific embodiment, it is considered that the wire diameter of the mounting wire portion, which is part of the fastening pin, is determined according to the size of the back surface or connecting member.

[0015] In this specific embodiment, the gap between the first locking portion and the second locking portion may be formed to extend in a direction perpendicular to the direction in which the first and second housing holes extend, or it may be formed to extend in a direction inclined with respect to the direction in which the first and second housing holes extend.

[0016] In the specific embodiment described in claim 3, the first opening and the second opening each have a wide opening portion that is set to the same size as or larger than the wire diameter of the mounting wire portion of the fastening pin, and a narrow opening portion that is set to be smaller than the wire diameter of the mounting wire portion of the fastening pin and is elastically deformable, wherein the wide opening portion is formed closer to the position of the gap between the first locking portion and the second locking portion than the narrow opening portion.

[0017] In this specific embodiment, the narrow opening portion may be positioned at the end of each opening that is furthest from the spacing position, or it may be positioned closer to the spacing position than the end of each opening that is furthest from the spacing position.

[0018] In the specific embodiment described in claim 4, the wide opening portion is formed in a first region determined from the end of each of the first and second openings that is closest to the position of the spacing between the first and second locking portions, and the narrow opening portion is formed in a second region determined from the other end of each of the first and second openings that is furthest from the position of the spacing between the first and second locking portions.

[0019] In the specific embodiment described in claim 5, each of the first opening and the second opening includes a continuous inclined portion that gradually narrows from a wider opening to a narrower opening.

[0020] In the specific embodiment described in claim 6, the length of the first region where a wide opening is formed is set to be longer than the sum of the length of the second region where a narrow opening is formed and the length of the region where an inclined portion is formed, in the direction in which each of the first and second accommodation holes extends.

[0021] In the specific embodiment described in claim 7, the gap between the first locking portion and the second locking portion is formed to extend in a direction perpendicular to the direction in which the first and second housing holes extend.

[0022] In the specific embodiment according to claim 8, in the direction in which the first receiving hole and the second receiving hole extend, the length of each locking portion of the first locking portion and the second locking portion is set to be larger than the width of the interval that can be opened between the first locking portion and the second locking portion.

[0023] In this specific embodiment, the length of the first locking portion and the length of the second locking portion do not necessarily need to be set to the same length. Also, the length of each locking portion may be any length as long as each locking portion can support the attachment wire portion of the fastening pin when the batch to be attached to the attached object by the fastening pin is pulled in either the upward or downward direction.

[0024] In the specific embodiment according to claim 9, in the direction in which the first receiving hole and the second receiving hole extend, the length of the first locking portion and the length of the second locking portion are set to the same length.

[0025] In the specific embodiment according to claim 10, the first locking portion and the second locking portion are integrally formed with the back surface portion or the connecting member by a synthetic resin material so as to protrude from the back surface portion or the flat surface of the connecting member.

[0026] In this specific embodiment, in the back surface portion or the connecting member, it is not necessary for the entire surface on the side where the first locking portion and the second locking portion are arranged to be formed flat. It is preferable that the surface that the attachment wire portion of the fastening pin contacts is formed flat while the attachment wire portion moves by rotating or the like until it is inserted into each opening.

[0027] In the specific embodiment according to claim 11, at the molding positions of the first locking portion and the second locking portion integrally formed with the back surface portion or the connecting member, first through grooves and second through grooves are respectively formed penetrating the back surface portion or the connecting member in a direction perpendicular to the flat surface of the back surface portion or the connecting member, and a partition wall portion partitioning the first through groove and the second through groove is arranged inside the interval opened between the first locking portion and the second locking portion.

[0028] In the specific embodiment described in claim 12, the partition wall portion has a flat wall surface that is formed in continuous with the back surface or the flat surface of the connecting member.

[0029] (Second embodiment of the invention and its specific embodiment) A second embodiment of the invention described in claim 13 is a fastening pin attachment structure for a badge to be attached to an object such as clothing, which includes a fastening pin with a mounting wire portion attached to a back surface fixed to a front surface on which a display such as characters or patterns is arranged, or to a connecting member connected to the back surface, wherein the fastening pin comprises a first locking portion and a second locking portion for attaching the mounting wire portion of the fastening pin to the back surface or the connecting member. In this embodiment of the invention, the first locking portion and the second locking portion each have a first housing hole and a second housing hole for housing the mounting wire portion of the fastening pin, and the first locking portion and the second locking portion are spaced apart on the back surface or the connecting member such that the first housing hole and the second housing hole are aligned in a straight line, and the first locking portion has a first opening that opens the first housing hole in a direction perpendicular to the direction in which the first housing hole extends, and the second The locking portion has a second opening that opens the second housing hole in a direction perpendicular to the direction in which the second housing hole extends, and in the opposite direction to the direction in which the first opening opens the first housing hole. The first and second openings are set to be smaller than the wire diameter of the mounting wire portion of the fastening pin and each includes a narrow, elastically deformable opening portion, and the first and second openings are formed to communicate with the gap created between the first locking portion and the second locking portion.

[0030] Generally, the size of a fastening pin is determined according to the size of the object to which it is attached. In the embodiment of the present invention, the size of the fastening pin is determined to be suitable for the size of the back surface or the connecting member. The wire diameter of the mounting wire portion of the fastening pin is considered to be determined according to the size of the fastening pin.

[0031] The embodiments of the present invention are embodied in various forms, as described in the First Embodiment and its specific embodiments.

[0032] In the specific embodiment described in claim 14, the first opening and the second opening each have a wide opening portion set to the same size as or larger than the wire diameter of the mounting wire portion of the fastening pin, a narrow opening portion set to a size smaller than the wire diameter of the mounting wire portion of the fastening pin and elastically deformable, and an inclined portion that gradually narrows from the wide opening portion to the narrow opening portion, wherein the wide opening portion is formed closer to the position of the gap between the first locking portion and the second locking portion than the position of the narrow opening portion, and the inclined portions of each opening are positioned such that when the mounting wire portion of the fastening pin is rotated to a position where the angle it makes with the direction in which the first and second housing holes extend is less than 45 degrees, the mounting wire portion of the fastening pin engages with the inclined portions of each opening of the first and second openings.

[0033] In the specific embodiment described in claim 15, the fastening pin includes a mounting wire portion attached to the back surface or a connecting member, a mounting wire portion attached to an object to be attached such as clothing, an elastically deformable curved portion connecting one end of the mounting wire portion and the other end of the mounting wire portion, and a holding portion fixed to the other end of the mounting wire portion and holding the other end of the mounting wire portion in a releaseable manner, wherein the sum of the length of the first locking portion and the length of the second locking portion is set in the direction in which the first and second housing holes extend, such that a length range of 2 / 3 or more of the length of the mounting wire portion positioned between the curved portion and the holding portion is accommodated inside the first and second housing holes.

[0034] (Third aspect of the invention) A third embodiment of the invention described in claim 16 is a badge which is attached to an object to be worn, such as clothing, by fastening pins, and a first locking portion and a second locking portion for attaching the mounting wire portion of fastening pins to the back portion or a connecting member connected to the back portion. The badge comprises a front surface on which characters, patterns, or other markings are arranged, a back surface fixed to the front surface, and a fastening pin formed from a wire, which includes a mounting wire portion attached to the back surface or a connecting member connected to the back surface. In this embodiment of the present invention, the first locking portion and the second locking portion each have a first housing hole and a second housing hole for housing the mounting wire portion of the fastening pin, and the first locking portion and the second locking portion are arranged on the back surface or the connecting member such that the first housing hole and the second housing hole are aligned in a straight line, and the first locking portion has a first opening that opens the first housing hole in a direction perpendicular to the direction in which the first housing hole extends, and the second locking portion has a second In a direction perpendicular to the direction in which the housing hole extends, the first opening has a second opening that opens a second housing hole in the opposite direction to the direction in which the first opening opens the first housing hole, and the first and second openings are set to be smaller than the wire diameter of the mounting wire portion of the fastening pin and each includes a narrow opening portion that is elastically deformable, and the first and second openings are formed to communicate with the gap or slit formed between the first locking portion and the second locking portion.

[0035] The embodiments of the present invention are embodied in various forms, as described in the First Embodiment, the Second Embodiment, and their specific embodiments. [Effects of the Invention]

[0036] (Effects of the first embodiment of the invention and its specific embodiment) In the first embodiment of the invention described in claim 1, the first locking portion and the second locking portion each have a first housing hole and a second housing hole for housing a portion of a fastening pin, and the first locking portion and the second locking portion are arranged on the back surface or the connecting member such that the first housing hole and the second housing hole are aligned in a straight line. The first locking portion has a first opening that opens the first housing hole in a direction perpendicular to the direction in which the first housing hole extends, and the second locking portion has a second opening that opens the second housing hole in a direction perpendicular to the direction in which the second housing hole extends, in the opposite direction to the direction in which the first opening opens the first housing hole. The first opening and the second opening each include an elastically deformable opening portion for holding a portion of the fastening pin in the first housing hole and the second housing hole, respectively. The first and second openings are formed to communicate with the gap or slit formed between the first and second locking portions. This configuration allows a portion of the fastening pin to move through the gap or slit formed between the two locking portions to both openings. The portion of the fastening pin is inserted into and held inside both housing holes by the elastic deformation of the openings. As a result, since the two openings of the two locking portions open in opposite directions, even when the batch attached to the object by the fastening pin is pulled in either an upward or downward direction, a portion of the fastening pin is locked by either the locking portion of the two locking portions, reliably reducing the chance of a portion of the fastening pin coming off the back surface or connecting member. Furthermore, since a portion of the fastening pin is locked by either the locking portion of the two locking portions, a configuration with a large elastic deformation force in the opening portion is not required, making the process of assembling the fastening pin to the back surface or connecting member easier, whether done manually by an operator or automatically by machine.

[0037] In the specific embodiment described in claim 2, the gap between the first locking portion and the second locking portion is set to be larger than the wire diameter of the mounting wire portion, which is part of the fastening pin attached to the back surface or the connecting member. As a result, it becomes easier to insert the mounting wire portion, which is part of the fastening pin, into the interior of both openings through the gap between the two locking portions.

[0038] In the specific embodiment described in claim 3, the first opening and the second opening each have a wide opening portion set to the same size as or larger than the wire diameter of the mounting wire portion of the fastening pin, and a narrow opening portion set to be smaller than the wire diameter of the mounting wire portion of the fastening pin and elastically deformable, wherein the wide opening portion is formed closer to the position of the gap between the first locking portion and the second locking portion than the narrow opening portion. As a result, it becomes easier to move the mounting wire portion of the fastening pin from the wide opening portion to the narrow opening portion.

[0039] In the specific embodiment described in claim 4, the wide opening portion is formed in a first region determined from the end of each of the first and second openings closest to the position of the spacing between the first and second locking portions, and the narrow opening portion is formed in a second region determined from the other end of each of the first and second openings furthest from the position of the spacing between the first and second locking portions. As a result, since the narrow opening portion is formed in the second region determined from the other end furthest from the position of the spacing, the rotational moment of the mounting wire portion of the fastening pin rotating around the position of the spacing becomes relatively large, and the likelihood of the mounting wire portion of the fastening pin coming out of both narrow openings can be reduced.

[0040] In the specific embodiment described in claim 5, each of the first and second openings includes a continuous inclined portion that gradually narrows from a wider opening to a narrower opening. As a result, the mounting wire portion of the fastening pin can be smoothly moved along the inclined portion from the wider opening to the narrower opening.

[0041] In the specific embodiment described in claim 6, the length of the first region where the wide opening is formed is set to be longer than the sum of the length of the second region where the narrow opening is formed and the length of the region where the inclined portion is formed. As a result, the distance over which the mounting wire portion of the fastening pin is engaged with and moved in the inclined portion and the narrow opening can be shortened, making it easier to attach the fastening pin.

[0042] In the specific embodiment described in claim 7, the gap between the first locking portion and the second locking portion is formed to extend in a direction perpendicular to the direction in which the first and second housing holes extend. As a result, the mounting wire portion of the fastening pin, which is inserted into the gap extending in the perpendicular direction, can be fitted into both wide openings by only a slight rotation, and the mounting wire portion of the fastening pin can be reliably moved to the narrow opening without falling out of either opening.

[0043] In the specific embodiment described in claim 8, the lengths of the first locking portion and the second locking portion are set to be greater than the width of the gap between the first locking portion and the second locking portion in the direction in which the first and second housing holes extend. As a result, since the length of each locking portion is greater than the width of the gap, the mounting wire portion of the fastening pin can be held inside the housing hole by only the unopened portion on the opposite side of the opening of one of the locking portions, regardless of whether the badge attached to the object to be attached is pulled in an upward or downward direction.

[0044] In the specific embodiment described in claim 9, the length of the first locking portion and the length of the second locking portion are set to be the same in the direction in which the first and second housing holes extend. As a result, since the lengths of both locking portions are the same, the non-opening portion on the opposite side of the opening in each locking portion is also the same length, and the mounting wire portion of the fastening pin can be held inside the housing hole by the non-opening portion of each locking portion, regardless of whether the badge attached to the object to be attached is pulled in an upward or downward direction.

[0045] In the specific embodiment described in claim 10, the first locking portion and the second locking portion are molded integrally with the back surface or connecting member from a synthetic resin material so as to protrude from the back surface or the flat surface of the connecting member. As a result, it becomes easier to guide the mounting wire portion of the fastening pin along the back surface or the flat surface of the connecting member to both openings.

[0046] In the specific embodiment described in claim 11, a first through groove and a second through groove are formed at the molding positions of the back surface or the connecting member, which are integrally molded with the back surface or the connecting member, in a direction perpendicular to the flat surface of the back surface or the connecting member, and a partition wall is arranged within the gap between the first and second locking parts, separating the first and second through grooves. As a result, compared to a configuration in which both through grooves necessary for molding both locking parts are connected, the configuration in which the partition wall is arranged can increase the rigidity of the unopened portion on the opposite side of the opening in each locking part.

[0047] In the specific embodiment described in claim 12, the partition wall portion has a flat wall surface that is formed in continuous with the back surface or the flat surface of the connecting member. As a result, the mounting wire portion of the fastening pin can be smoothly moved from the spacing made in both locking portions to each opening along the back surface or the flat surface of the connecting member and the flat wall surface.

[0048] (Second embodiment of the invention and its effects) In the second embodiment of the invention described in claim 13, the first locking portion and the second locking portion each have a first housing hole and a second housing hole for housing the mounting wire portion of the fastening pin, and the first locking portion and the second locking portion are arranged on the back surface or connecting member with a gap between them such that the first housing hole and the second housing hole are aligned in a straight line. The first locking portion has a first opening that opens the first housing hole in a direction perpendicular to the direction in which the first housing hole extends, and the second locking portion has a second opening that opens the second housing hole in a direction perpendicular to the direction in which the second housing hole extends, in the opposite direction to the direction in which the first opening opens the first housing hole. The first opening and the second opening each include a narrow opening portion that is smaller than the wire diameter of the mounting wire portion of the fastening pin and is elastically deformable. The first and second openings are formed to communicate with the gap between the first and second locking portions. This configuration allows the mounting wire portion of the fastening pin to move through the gap formed between the two locking portions to both openings. The mounting wire portion of the fastening pin is inserted into and held inside both housing holes by the elastic deformation of the narrow openings. As a result, since the two openings of the two locking portions open in opposite directions, the mounting wire portion of the fastening pin is secured by either the locking portion of the two locking portions regardless of whether the batch attached to the object by the fastening pin is pulled upward or downward, thereby reliably reducing the chance of the mounting wire portion of the fastening pin coming off the back surface or the connecting member. Furthermore, since the mounting wire portion of the fastening pin is secured by either of the two locking parts, a configuration with a large elastic deformation force in the narrow opening is not required, making the process of assembling the fastening pin to the back surface or connecting member easier, whether done manually by an operator or automatically by machine.

[0049] In the specific embodiment described in claim 14, the first opening and the second opening each have a wide opening portion, an elastically deformable narrow opening portion, and an inclined portion. The wide opening portion is formed closer to the position of the gap between the first locking portion and the second locking portion than the narrow opening portion. When the mounting wire portion of the fastening pin is rotated to a position where the angle it makes with the direction in which the first and second housing holes extend is less than 45 degrees, around the position of the gap between the first and second locking portions, the inclined portions of each opening are positioned such that the mounting wire portion of the fastening pin engages with the inclined portions of each opening. As a result, the mounting wire portion of the fastening pin can be rotated to a position where the angle it makes with the direction in which both housing holes extend is less than 45 degrees when it engages with the inclined portions of each opening. In this rotated position, the mounting wire portion of the locking pin is held in place by the wider openings of each opening, regardless of its own gravity. This prevents the mounting wire portion of the locking pin from falling out of both locking parts, and allows the mounting wire portion to be further rotated to securely engage with the narrower openings of each opening.

[0050] In the specific embodiment described in claim 15, the fastening pin includes a mounting wire portion attached to the back surface or a connecting member, a mounting wire portion attached to an object to be attached, such as clothing, an elastically deformable curved portion connecting one end of the mounting wire portion and one end of the mounting wire portion, and a holding portion fixed to the other end of the mounting wire portion and holding the other end of the mounting wire portion in a releaseable manner. The sum of the lengths of the first locking portion and the second locking portion is set in the direction in which both housing holes extend, such that a length range of 2 / 3 or more of the length of the mounting wire portion positioned between the curved portion and the holding portion is accommodated inside both housing holes. As a result, since a length range of 2 / 3 or more of the length of the mounting wire portion is locked by both locking portions, it is possible to reliably reduce the likelihood of the mounting wire portion of the fastening pin coming off the back surface or the connecting member, regardless of whether the badge attached to the object by the fastening pin is pulled in an upward or downward direction.

[0051] (Effects of the third embodiment of the invention) In the third embodiment of the invention described in claim 16, the first locking portion and the second locking portion each have a first housing hole and a second housing hole for housing the mounting wire portion of the fastening pin, and the first locking portion and the second locking portion are arranged on the back surface or the connecting member such that the first housing hole and the second housing hole are aligned in a straight line. The first locking portion has a first opening that opens the first housing hole in a direction perpendicular to the direction in which the first housing hole extends, and the second locking portion has a second opening that opens the second housing hole in a direction perpendicular to the direction in which the second housing hole extends, in the opposite direction to the direction in which the first opening opens the first housing hole. The first opening and the second opening each include a narrow opening portion that is smaller than the wire diameter of the mounting wire portion of the fastening pin and is elastically deformable. The first and second openings are formed to communicate with the gap or slit formed between the first and second locking portions. This configuration allows the mounting wire portion of the fastening pin to move through the gap or slit formed between the two locking portions to both openings. The mounting wire portion of the fastening pin is inserted into and held inside both housing holes by the elastic deformation of the narrow openings. As a result, since the two openings of the two locking portions open in opposite directions, the mounting wire portion of the fastening pin is secured by either the locking portion of the two locking portions regardless of whether the batch attached to the object by the fastening pin is pulled upward or downward, thereby reliably reducing the chance of the mounting wire portion of the fastening pin coming off the back surface or connecting member. Furthermore, since the mounting wire portion of the fastening pin is secured by either of the two locking parts, a configuration with a large elastic deformation force in the narrow opening is not required, making the process of assembling the fastening pin to the back surface or connecting member easier, whether done manually by an operator or automatically by machine.

The display surface portion 20 has a front surface that is formed to curve outward. The patterned paper on which characters, symbols, patterns, etc. are drawn is covered with a transparent sheet, and the patterned paper and the transparent sheet are placed on the front surface of the display surface portion 20. The peripheral edge portion 22 is formed by folding the circular periphery of the display surface portion 20 backward. The cover body 10 is formed by processing a metal material, such as by press working.

[0055] [Composition of Safety Pin 14] The structure of the safety pin 14 will be explained with reference to Figure 2. Figure 2 shows the safety pin 14 alone. The safety pin 14 includes an attachment wire portion 30, an attachment wire portion 32 that is attached to an object to be attached, such as clothing, an elastically deformable curved portion 34 that connects the left end of the attachment wire portion 30 and the left end of the attachment wire portion 32, and a holding portion 36 that is fixed to the right end of the attachment wire portion 30 and holds the needle-shaped right tip of the attachment wire portion 32 in a releaseable manner. The attachment wire portion 30, the attachment wire portion 32, and the curved portion 34 are formed by bending a wire-like material.

[0056] The mounting wire portion 30 includes a mounting straight portion 30A that extends substantially in a straight line in the left-right direction between the curved portion 34 and the holding portion 36. The mounting straight portion 30A has a length LA as shown in Figure 2. Generally, safety pins of multiple sizes with different lengths LA of the mounting straight portion 30A and wire diameter DA, which is the diameter of the wire forming the mounting straight portion 30A, are prepared in advance. In this embodiment, the safety pin 14 is a safety pin of a size that fits the size of the back cover 12 so as not to protrude from the back cover 12.

[0057] [Detailed configuration of case back 12] The detailed configuration of the case back 12 will be explained with reference to Figures 3 to 6. Figure 3 shows the case back 12 viewed from the rear. Figure 4 shows the case back 12 viewed from above, Figure 5 shows the case back 12 viewed from the left, and Figure 6 shows the case back 12 viewed from the front. Figures 4 and 5 show a portion of the peripheral edge 44 of the case back 12, which will be described later, cut away.

[0058] In Figure 3, the case back 12 is formed in a disc shape and includes a first locking portion 40, a second locking portion 42, a peripheral portion 44, and a circular flat surface portion 46. The case back 12, together with the first locking portion 40 and the second locking portion 42, is integrally molded from a synthetic resin material. In this embodiment, polypropylene, which is elastically deformable and durable, is used as the synthetic resin material. Other synthetic resin materials such as polycarbonate and polyacetal can also be used as the synthetic resin material.

[0059] As shown in Figure 4, the first locking portion 40 and the second locking portion 42 are formed to protrude rearward from the flat surface portion 46. In Figure 3, the first locking portion 40 and the second locking portion 42 are arranged in a straight line in the left-right direction at a position slightly above the center position CP of the circular flat surface portion 46. The first locking portion 40 and the second locking portion 42 are arranged with a gap 48 between them. The gap 48 is located on an extension line CL that extends vertically through the center position CP of the flat surface portion 46 and is formed to extend openly in the vertical direction. As shown in Figure 4, the gap 48 has a width SA in the left-right direction. In this embodiment, the width SA of the gap 48 is set to the same dimension as the wire diameter DA of the mounting straight portion 30A of the safety pin 14, or to a slightly larger dimension.

[0060] As shown in Figure 4, the first locking portion 40 and the second locking portion 42 have lengths L1 and L2, respectively, in the left-right direction. In this embodiment, lengths L1 and L2 are the same length and are set to be sufficiently longer than the width SA of the spacing 48. Also in this embodiment, the sum of lengths L1 and L2 is set to be at least 2 / 3 of the length LA of the mounting straight portion 30A of the safety pin 14, for example, 4 / 5 of the length LA. As a result, when the safety pin 14 is locked to the first locking portion 40 and the second locking portion 42, as shown in Figure 1, most of the mounting straight portion 30A of the safety pin 14 is housed inside the housing holes of both locking portions 40 and 42, which will be described later.

[0061] As shown in Figure 4, the peripheral portion 44 is formed to protrude rearward from the flat surface portion 46. The flat surface portion 46 has a flat circular region 46A. In this embodiment, as shown in Figure 1, a safety pin 14 is used that is sized to be placed inside the circular region 46A of the flat surface portion 46.

[0062] In Figure 6, the back cover 12 has a first through groove 50 and a second through groove 52. The first through groove 50 and the second through groove 52 are necessary for integrally molding the back cover 12 together with the two locking parts 40 and 42. The first through groove 50 and the second through groove 52 are formed to penetrate the flat surface portion 46 in the front-rear direction. The partition wall portion 54 is positioned to separate the first through groove 50 and the second through groove 52, and is positioned to coincide with the arrangement position of the spacing 48. The rear flat surface of the partition wall portion 54 is formed to be a continuous surface with the rear flat surface of the flat surface portion 46.

[0063] (Detailed configuration of the first locking part 40 and the second locking part 42) The detailed configurations of the first locking portion 40 and the second locking portion 42 will be described with reference to Figures 7 to 10. The first locking portion 40 and the second locking portion 42 have substantially the same structure. The second locking portion 42 is positioned in a point-symmetric position to the first locking portion 40 with respect to the spacing 48 in Figure 3. Specifically, it is positioned in the same manner as if the first locking portion 40 were rotated 180 degrees around the spacing 48. Since both locking portions 40 and 42 have substantially the same structure, the second locking portion 42 will be used as an example for explanation. Figure 7 shows only the second locking portion 42 shown in Figure 3, enlarged, and illustrates the state in which the mounting straight portion 30A of the safety pin 14 is locked by the second locking portion 42. Figure 8 shows the second locking portion 42 shown in Figure 7 viewed from below, Figure 9 shows the second locking portion 42 shown in Figure 7 viewed from the left, and Figure 10 shows the second locking portion 42 shown in Figure 7 viewed from the right.

[0064] The second locking portion 42 has a second housing hole 70 and a second opening 72. As shown in Figure 7, the second housing hole 70 is formed to extend through the second locking portion 42 in the left-right direction. As shown in Figure 9, the second housing hole 70 has a vertical dimension that is slightly larger than the wire diameter DA of the mounting straight portion 30A and a front-back dimension that is sufficiently larger than the wire diameter DA, so that it can accommodate the mounting straight portion 30A of the safety pin 14. The second opening 72 is formed in the lower part of the second locking portion 42 so as to open downwards to the second housing hole 70. In Figure 8, the second opening 72 includes a wide opening portion 74, a narrow opening portion 76, and an inclined opening portion 78. The wide opening portion 74 is located on the left side of the second locking portion 42 so as to communicate with the spacing 48. The narrow opening portion 76 is located on the right side of the second locking portion 42. The inclined opening 78 is sloped so as to gradually narrow towards the right, connecting the wide opening 74 and the narrow opening 76 with a smooth inclined surface.

[0065] The wide opening 74 has an opening dimension H21, which is the dimension in the front-rear direction from the flat surface 46, as shown in Figure 9. The opening dimension H21 is set to be approximately the same size as the wire diameter DA of the mounting straight portion 30A of the safety pin 14. The narrow opening 76 has an opening dimension H22, which is the dimension in the front-rear direction from the flat surface 46, as shown in Figure 10. The opening dimension H22 is set to be smaller than half the wire diameter DA of the mounting straight portion 30A of the safety pin 14. In this embodiment, the opening dimension H22 is set to approximately 2 / 5 of the wire diameter DA.

[0066] In Figure 8, the wide opening 74 has an opening length L21 in the left-right direction, the narrow opening 76 has an opening length L22 in the left-right direction, and the inclined opening 78 has an opening length L23 in the left-right direction. The opening length L21 of the wide opening 74 is set to be greater than half of the left-right length L2 of the second locking portion 42. The opening length L22 of the narrow opening 76 is set to be approximately the same length as the opening length L23 of the inclined opening 78.

[0067] The first locking portion 40, like the second locking portion 42, has a first housing hole 60 and a first opening 62. The first housing hole 60 is formed to extend through the first locking portion 40 in the left-right direction shown in Figure 3, and is aligned in a straight line with the second housing hole 70 of the second locking portion 42 in the left-right direction. The first housing hole 60 has a vertical dimension that is slightly larger than the wire diameter DA of the mounting straight portion 30A, and a front-rear dimension that is sufficiently larger than the wire diameter DA, so that it can accommodate the mounting straight portion 30A of the safety pin 14. The first opening 62 is formed in the upper part of the first locking portion 40 so that the first housing hole 60 opens upward in Figure 3. The first opening 62, like the second opening 72, includes a wide opening portion 64, a narrow opening portion 66, and an inclined opening portion 68. The wide opening 64 is positioned to the right of the first locking portion 42 so as to communicate with the spacing 48. The narrow opening 66 is positioned to the left of the first locking portion 40. The inclined opening 68 is inclined to gradually narrow towards the left, connecting the wide opening 64 and the narrow opening 66 with a smooth inclined surface.

[0068] The wide opening 64 has an opening dimension H11, which is the dimension in the front-rear direction from the flat surface 46. The opening dimension H11 is set to be approximately the same size as the wire diameter DA of the mounting straight portion 30A of the safety pin 14. The narrow opening 66 has an opening dimension H12, which is the dimension in the front-rear direction from the flat surface 46. The opening dimension H12 is set to be smaller than half the wire diameter DA of the mounting straight portion 30A of the safety pin 14. In this embodiment, the opening dimension H12 is set to approximately 2 / 5 of the wire diameter DA.

[0069] The wide opening 64, the narrow opening 66, and the inclined opening 68 each have opening lengths L11 to L13 in the left-right direction, similar to the second opening 72. The opening length L11 of the wide opening 64 is set to be greater than half the left-right length L1 of the first locking portion 40. The opening length L12 of the narrow opening 66 is set to be approximately the same length as the opening length L13 of the inclined opening 68.

[0070] [Operation and Function of the Embodiment] The procedure for an operator to attach the safety pin 14 to the first locking portion 40 and the second locking portion 42 of the back cover 12 will be explained with reference mainly to Figures 11 to 13. Figures 11 to 13 show the state in which the mounting wire portion 30 of the safety pin 14 is in contact with the flat surface of the flat surface portion 46 of the back cover 12 and the flat surface at the interval 48, and also show a portion of the mounting wire portion 32 of the safety pin 14 broken off. In this embodiment, the procedure for manual installation by an operator will be explained.

[0071] In Figure 11, the worker inserts the mounting wire portion 30 of the safety pin 14 into the gap 48 with the holding portion 36 of the safety pin 14 facing downwards. When inserting the mounting wire portion 30, the worker applies force to press the mounting wire portion 30 against the flat surface of the flat surface portion 46 and the flat surface of the gap 48.

[0072] In Figure 12, the worker rotates the entire safety pin 14 clockwise. As the safety pin 14 rotates, the lower part of the mounting wire portion 30 of the safety pin 14 is fitted into the wide opening 74 that communicates with the spacing 48, and the upper part of the mounting wire portion 30 of the safety pin 14 is fitted into the wide opening 64 that communicates with the spacing 48. Since the opening dimensions H11 of the wide opening 64 and H21 of the wide opening 74 are set to be approximately the same size as the wire diameter DA of the mounting straight portion 30A of the safety pin 14, the worker can smoothly move the mounting wire portion 30 of the safety pin 14 from the spacing 48 into the interiors of both wide openings 64 and 74 using only the force of rotating the safety pin 14. When the mounting wire portion 30 of the safety pin 14 is fitted into both wide openings 64 and 74, the safety pin 14 will not fall due to its own weight, even if the worker is not holding the safety pin 14 with their fingers, as the safety pin 14 will be held inside both wide openings 64 and 74.

[0073] When the operator rotates the safety pin 14 clockwise to the angle θ shown in Figure 12, the lower portion of the mounting wire portion 30 of the safety pin 14 begins to engage with the inclined opening portion 78, and the upper portion of the mounting wire portion 30 of the safety pin 14 begins to engage with the inclined opening portion 68. The angle θ is the angle formed by the left-right direction in which both housing holes 60 and 70 extend and the direction in which the mounting wire portion 30 extends. In this embodiment, the angle θ is less than 45 degrees, and specifically, it is set to approximately 25 degrees.

[0074] When the worker further rotates the safety pin 14 clockwise from the angle θ shown in Figure 12, the lower part of the mounting wire portion 30 of the safety pin 14 moves along the inclined surface of the inclined opening 78 toward the narrower opening 76, while elastically deforming the inclined opening 78. At the same time, the upper part of the mounting wire portion 30 of the safety pin 14 moves along the inclined surface of the inclined opening 68 toward the narrower opening 66, while elastically deforming the inclined opening 68. Since the lower and upper parts of the mounting wire portion 30 engage with the inclined surfaces of both inclined openings 68 and 78, respectively, the worker does not need to apply any additional force to press the mounting wire portion 30 of the safety pin 14 toward the flat surface portion 46. By simply applying rotational force to the safety pin 14, the mounting wire portion 30 can be moved toward the narrower openings 66 and 76.

[0075] As the worker continues to rotate the safety pin 14 clockwise, the lower portion of the mounting wire portion 30 of the safety pin 14 moves toward the right end of the second locking portion 42 while elastically deforming the narrow opening portion 76, and the upper portion of the mounting wire portion 30 of the safety pin 14 moves toward the left end of the first locking portion 40 while elastically deforming the narrow opening portion 66.

[0076] When the worker rotates the safety pin 14 to the horizontal position shown in Figure 13, the mounting wire portion 30 of the safety pin 14 fits into and is held in place by the housing holes 60 and 70 of both locking portions 40 and 42. This completes the process of attaching the safety pin 14 to the back cover 12.

[0077] A well-known batch manufacturing apparatus is used to assemble the back cover 12, to which the safety pin 12 is attached, onto the front cover 10. Specifically, with a patterned paper and a transparent sheet (not shown) placed on the curved front surface of the front cover 10, the patterned paper and the transparent sheet are sandwiched between the peripheral edge 22 of the front cover 10 and the peripheral edge 44 of the back cover 12. With the patterned paper and the transparent sheet sandwiched between the two peripheral edges 22 and 44, the batch manufacturing apparatus bends the peripheral edge 22 of the front cover 10 toward the peripheral edge 44 of the back cover 12. This allows the back cover 12 to be assembled onto the front cover 10.

[0078] [Effects of the Embodiment] In this embodiment, the first opening 62 of the first locking portion 40 is configured to open upward, and the second opening 72 of the second locking portion 42 is configured to open downward. With this configuration, in Figure 13, when the badge 1, which is attached to clothing or the like by a safety pin 14, is pulled upward, the back cover 12 of the badge 1 moves upward, but the lower portion of the first locking portion 40, which is not open, can reliably hold the mounting wire portion 30 of the safety pin 14 inside the first housing hole 60. Also, when the badge 1 is pulled downward, the back cover 12 of the badge 1 moves downward, but the upper portion of the second locking portion 42, which is not open, can reliably hold the mounting wire portion 30 of the safety pin 14 inside the second housing hole 70.

[0079] In this embodiment, the length L1 of the first locking portion 40 and the length L2 of the second locking portion 42 are set to the same length. Furthermore, the sum of lengths L1 and L2 is set to be at least 2 / 3 of the length LA of the mounting straight portion 30A of the safety pin 14. With this configuration, as shown in Figure 13, most of the mounting straight portion 30A is locked by the first locking portion 40 and the second locking portion 42, so that the safety pin 14 can be reliably held in place on the back cover 12 even when the batch 1 is pulled upward or downward.

[0080] In this embodiment, in the case back 12 molded from a synthetic resin material, the partition wall 54 is configured to separate the first through groove 50 and the second through groove 52. This configuration increases the rigidity of the partition wall 54 between the lower portion of the closed first locking portion 40 and the upper portion of the closed second locking portion 42. This increase in rigidity ensures that the safety pin 14 is securely held in place by the case back 12.

[0081] In this embodiment, the wide opening portion 64 of the first opening 62 and the wide opening portion 74 of the second opening 72 are configured to communicate with the gap 48 created between the first locking portion 40 and the second locking portion 42. With this configuration, in Figure 11, by fitting the mounting wire portion 30 of the safety pin 14 into the gap 48 and rotating it by a small angle in the clockwise direction, the upper portion of the mounting wire portion 30 can be smoothly moved from the gap 48 to the wide opening portion 64, and the lower portion of the mounting wire portion 30 can be smoothly moved from the gap 48 to the wide opening portion 74.

[0082] In this embodiment, when the mounting wire portion 30 of the safety pin 14 is rotated around the position of the spacing 48 between the first locking portion 40 and the second locking portion 42 to a position where the angle it makes with the left-right direction in which the first housing hole 60 and the second housing hole 70 extend is less than 45 degrees, the inclined opening portions 68 and 78 of the first opening 62 and the second opening 72 are positioned such that the mounting wire portion 30 of the safety pin 14 engages with the inclined opening portions 68 and 78 of the first opening 62 and the second opening 72. As a result, when the mounting wire portion 30 of the safety pin 14 engages with the inclined opening portions 68 and 78, it can rotate to a position where the angle it makes with the left-right direction in which both housing holes 60 and 70 extend is less than 45 degrees. In this rotated position, the mounting wire portion 30 of the safety pin 14 is held in place by fitting into both wide openings 64 and 74, regardless of its own gravity. This prevents the mounting wire portion 30 of the safety pin 14 from falling out of the locking portions 40 and 42, and allows the mounting wire portion 30 to be rotated further to securely engage with both narrow openings 66 and 76.

[0083] In this embodiment, the opening length L11 of the wide opening 64 is set to be greater than half the left-right length L1 of the first locking portion 40, and the opening length L21 of the wide opening 74 is set to be greater than half the left-right length L2 of the second locking portion 42. Furthermore, the opening dimensions H11 and H21 of both wide openings 64 and 74 are set to be approximately the same size as the wire diameter DA of the mounting straight portion 30A of the safety pin 14. With this configuration, the safety pin 14 can be rotated with a small rotational force to the rotation position shown in Figure 12. At the rotation position shown in Figure 12, the mounting straight portion 30A of the safety pin 14 is fitted into both openings 62 and 72, thus reducing the risk of the safety pin 14 coming loose from both openings 62 and 72 and falling during the assembly process of the safety pin 14.

[0084] In this embodiment, the inclined opening portion 68 of the first opening 62 connects the wide opening portion 64 and the narrow opening portion 66 by a continuous inclined surface, and the inclined opening portion 78 of the second opening 72 is configured to connect the wide opening portion 74 and the narrow opening portion 76 by a continuous inclined surface. With this configuration, when the safety pin 14 is rotated from the rotation position shown in Figure 12, the upper portion of the mounting wire portion 30 of the safety pin 14 moves toward the narrow opening portion 66 along the inclined surface of the inclined opening portion 68, and the lower portion of the mounting wire portion 30 of the safety pin 14 moves toward the narrow opening portion 76 along the inclined surface of the inclined opening portion 78. As a result, the mounting wire portion 30 of the safety pin 14 can be fitted into both narrow opening portions 66 and 76 by applying a rotational force to the safety pin 14, without applying a force to press the mounting wire portion 30 of the safety pin 14 against the flat surface portion 46 of the back cover 4.

[0085] In this embodiment, the flat surface of the gap 48 and the flat surface of the flat surface portion 46 of the back cover 12 are configured to form a single continuous surface. With this configuration, after inserting the mounting wire portion 30 of the safety pin 14 into the gap 48, the mounting wire portion 30 can be easily rotated and moved to both wide openings 64 and 74 by bringing it into contact with the flat surface of the gap 48 and the flat surface portion 46, respectively.

[0086] In this embodiment, the spacing 48 is formed to extend in a vertical direction perpendicular to the left-right direction in which the housing portions 60 and 70 of both locking portions 40 and 42 extend. With this configuration, when assembling the safety pin 14 manually, the worker only needs to visually check the direction in which the locking portions 40 and 42 extend and hold the safety pin 14 in a position perpendicular to that direction. Compared to a configuration in which the spacing 48 extends at an angle to the left-right direction in which the housing portions 60 and 70 extend, the mounting wire portion 30 of the safety pin 14 can be easily inserted into the spacing 48. Furthermore, by simply rotating the mounting wire portion 30 of the safety pin 14 inserted into the spacing 48 which extends in a perpendicular direction, it can be fitted into the wide openings 64 and 74, and the mounting wire portion 30 of the safety pin 14 can be reliably moved to the narrow openings 66 and 76 without falling out of the openings 62 and 72. Furthermore, the configuration in which the spacing 48 extends in a direction perpendicular to the left-right direction in which both housing sections 60 and 70 extend allows for a large ratio of the left-right lengths L11 and L21 of the two wider openings 64 and 74 to the total left-right length of both openings 62 and 72. By setting this ratio of length L11 and L21 to a large value, the rotational position and rotational orientation of the safety pin 14 can be reliably stabilized, as shown in Figure 12, before the worker applies a large rotational force to the safety pin 14 to elastically deform the two narrow openings 66 and 76.

[0087] In this embodiment, the wide openings 64 and 74 are formed in a first region (regions of length L11 and L21) determined from the end of each opening of the first opening 62 and the second opening 72 that is closest to the position of the spacing 48 between the first locking portion 40 and the second locking portion 42. The narrow openings 66 and 76 are formed in a second region (regions of length L12 and L22) determined from the other end of each opening of the first opening 62 and the second opening 72 that is furthest from the position of the spacing 48. As a result, since the narrow openings 66 and 76 are formed in a second region determined from the other end that is furthest from the position of the spacing 48, the rotational moment of the mounting wire portion 30 of the safety pin 14 as it rotates around the position of the spacing 48 becomes relatively large, and the likelihood of the mounting wire portion 30 of the safety pin 14 coming off both narrow openings 66 and 76 is reduced.

[0089] <Variation> The present invention is not limited to this embodiment, and various modifications are possible without departing from its spirit. An example of such modifications is described below.

[0090] (1) In this embodiment, the device is configured to have two locking parts, a first locking part 40 and a second locking part 42, but the device is not limited to this configuration. For example, each of the locking parts, the first locking part 40 and the second locking part 42, may be composed of two locking parts that are arranged separately.

[0091] (2) In this embodiment, each of the first locking portion 40 and the second locking portion 42 has a wide opening portion, a narrow opening portion, and an inclined opening portion, but is not limited to this configuration. For example, each locking portion may have a narrow opening portion and an inclined opening portion without a wide opening portion, or each locking portion may have a wide opening portion and an inclined opening portion without a narrow opening portion. Alternatively, each locking portion may have an inclined opening portion only, without a wide opening portion or a narrow opening portion. Or, if the difference in dimensions between the opening dimension H21 of the wide opening portion 74 and the opening dimension H22 of the narrow opening portion 76 is not large, each locking portion may have a wide opening portion and a narrow opening portion without an inclined opening portion.

[0092] (3) In this embodiment, as shown in Figure 3, a flat surface of the flat surface portion 46 is formed at the left end of the first locking portion 40 which opens through the first housing hole 60, and at the right end of the second locking portion 42 which opens through the second housing hole 70. However, the embodiment is not limited to this configuration.
