Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the invention disclosed in Patent Document 1 has a problem that it is difficult to easily recognize the completion of attachment.

[0006] An object of the present invention is that the completion of attachment can be easily recognized.

Means for Solving the Problems

[0007] The present invention will be described with reference to the drawings. The reference numerals in the drawings are used in this section to aid in understanding the content of the invention. The use of reference numerals in the drawings in this section is not intended to limit the content of the invention to the scope shown in the drawings.

[0008] To achieve the above-mentioned objective, according to one aspect of the present invention, the fastener 10 comprises an inner structure 20 and an outer structure 22. The outer structure 22 allows the inner structure 20 to enter. The inner structure 20 has an inner adhesive portion 30. The inner adhesive portion 30 has an adhesive surface 114. The adhesive surface 114 can adhere to a predetermined object 200. The outer structure 22 has a cylindrical outer body portion 70 and an outer adhesive portion 72. The outer body portion 70 forms a housing space 102. The inner structure 20 can enter the housing space 102. The outer adhesive portion 72 is located at one end of the outer body portion 70. In the outer adhesive portion 72, The reverse side when viewed from the other end of the outer body portion 70 Location 90 can be attached to a predetermined object 200. The inner structure 20 has an inner body portion 32 and an inner body adjacent outer peripheral protrusion portion 34 in addition to the inner attachable portion 30. The inner body portion 32 is connected to the back side of the attachable surface 114 of the inner attachable portion 30. A portion of the inner body portion 32 that is away from the inner attachable portion 30 is pre-housed in the housing space 102. The inner body adjacent outer peripheral protrusion portion 34 protrudes from the outer peripheral surface of the inner body portion 32 at a location closer to the inner attachable portion 30 than the portion that is pre-housed in the housing space 102. The outer structure 22 further has an outer body inner peripheral protrusion portion 74. The outer body inner peripheral protrusion portion 74 protrudes from the outer body portion 70 toward the housing space 102 so as to surround the inner body portion 32 at the position described below. This position is closer to one end of the outer body portion 70 than the inner body adjacent outer peripheral protrusion portion 34 when described below. At that time, of the outer attachable portion 72 The reverse side when viewed from the other end of the outer body portion 70This occurs when location 90 is positioned on the same plane as the attachable surface 114. When the inner body proximity outer peripheral protrusion 34 enters the housing space 102, the portion of the inner body 32 that has not yet entered the housing space 102 can pass through the opening formed by one end of the outer body 70 and the outer body inner peripheral protrusion 74. On the other hand, when the inner body proximity outer peripheral protrusion 34 enters the housing space 102 formed by the outer body 70, the inner body proximity outer peripheral protrusion 34 comes into contact with the outer body inner peripheral protrusion 74.

[0009] When the inner casing-adjacent outer peripheral protrusion 34 enters the housing space 102 formed by the outer casing 70, the portion of the inner casing 32 that has not yet entered the housing space 102 can freely pass through the opening formed by one end of the outer casing 70 and the inner casing-inner peripheral protrusion 74. Meanwhile, the inner casing-adjacent outer peripheral protrusion 34 comes into contact with the inner casing-inner peripheral protrusion 74. This contact creates resistance to the entry of the inner casing-adjacent outer peripheral protrusion 34 until it passes the point where the inner casing-inner peripheral protrusion 74 protrudes. Once the inner casing-adjacent outer peripheral protrusion 34 passes that point, the resistance disappears. After that, of the outer attachable portion 72 The reverse side when viewed from the other end of the outer body portion 70 Location 90 is positioned on the same plane as the adhesive surface 114. When location 90 and the adhesive surface 114 are positioned on the same plane, they both come into contact with the predetermined object 200. The passage of the outer peripheral protrusion 34 on the inner side of the casing is easily recognized by the occurrence of resistance to the entry of the inner side of the casing before this happens, and by the disappearance of that resistance. Of the inner adhesive portion 30 and the outer adhesive portion 72 The reverse side when viewed from the other end of the outer body portion 70 The part 90 is capable of adhering to a predetermined object 200. Since they are arranged on the same plane and are capable of adhering to the predetermined object 200, when the outer peripheral protrusion 34 on the side adjacent to the inner body enters the storage space 102, the inner adhesive part 30 and the outer adhesive part 72 are pressed against the predetermined object 200, and thus the fixing device 10 is attached to the predetermined object 200. The passage of the outer peripheral protrusion 34 on the side adjacent to the inner body is easily recognized, and the fixing device 10 is attached, so the completion of the attachment of the fixing device 10 to the predetermined object 200 is easily recognized.

[0010] Furthermore, it is desirable that the inner body portion 32 described above be cylindrical. In this case, it is desirable that a plurality of slits 152, 152 are formed on the side of the inner body portion 32 that is connected to the inner attachable portion 30. In this case, it is desirable that the outer peripheral protrusion portion 34 on the side adjacent to the inner body protrudes from one of the locations between the plurality of slits 152, 152 formed on the side of the inner body portion 32 that is connected to the inner attachable portion 30.

[0011] The outer peripheral protrusion 34 on the side adjacent to the inner casing extends from one of the locations between the multiple slits 152, 152 formed on the side connected to the inner adhesive portion 30. This prevents excessive resistance to the entry of the outer peripheral protrusion 34 on the side adjacent to the inner casing.

[0012] Alternatively, it is desirable that a plurality of slits 154, 154 are formed in the inner adhesive portion 30 described above. These plurality of slits 154, 154 are connected in a one-to-one ratio to a plurality of slits 152, 152 formed on the side of the inner body portion 32 that is connected to the inner adhesive portion 30.

[0013] The slit 154 formed in the inner adhesive portion 30 is connected one-to-one with a plurality of slits 152, 152 formed on the side of the inner barrel portion 32 that is connected to the inner adhesive portion 30. In this case, the range of motion of the outer peripheral protrusion portion 34 on the inner barrel side that protrudes from between the plurality of slits 152, 152 is larger compared to when the inner adhesive portion 30 does not have a slit 154. This increased range of motion further prevents excessive resistance to the entry of the outer peripheral protrusion portion 34 on the inner barrel side.

[0014] Alternatively, it is desirable that the multiple slits 154, 154 formed in the aforementioned inner adhesive portion 30 are spaced apart from each other.

[0015] Since the multiple slits 154, 154 formed in the inner adhesive portion 30 are spaced apart from each other, the region between these multiple slits 154, 154 is integrated. This integration of the region increases the rigidity of the inner adhesive portion 30 compared to the case where the multiple slits 154, 154 are connected to each other. This increased rigidity of the inner adhesive portion 30 prevents insufficient resistance to the entry of the outer peripheral protrusion 34 on the side adjacent to the inner body. The increased rigidity of the inner adhesive portion 30 ensures that when the outer peripheral protrusion 34 on the side adjacent to the inner body enters the housing space 102 and the inner adhesive portion 30 and the outer adhesive portion 72 are pressed against a predetermined object 200, the pressing becomes firmer.

[0016] Furthermore, it is desirable that a plurality of slits 150, 150 are formed at the end of the inner body portion 32 opposite to the side connected to the inner attachable portion 30. In this case, it is desirable that the inner structure 20 further has an outer peripheral protrusion portion 36 on the inner body separation side. The outer peripheral protrusion portion 36 on the inner body separation side protrudes at one of the locations between the plurality of slits 150, 150 formed at the opposite end. In this case, it is desirable that the outer peripheral protrusion portion 36 on the inner body separation side is housed in the housing space 102 in advance.

[0017] By having the outer peripheral protrusion 36 on the outer side of the inner body separated from the slits 150, 150 pre-housed within the housing space 102 at one of the locations between the multiple slits 150, 150, the inner structure 20 is less likely to fall out of the outer structure 22. By having the outer peripheral protrusion 36 on the outer side of the inner body separated from the slits 150, 150 protrude at one of the locations between the multiple slits 150, 150, it becomes easier for the outer peripheral protrusion 36 on the outer side of the inner body separated from the slits 36 to pre-house within the housing space 102.

[0018] Alternatively, it is desirable that the outer peripheral protrusion 36 on the inner shell separation side described above be positioned so as to cross the outer peripheral protrusion 34 on the inner shell proximity side when viewed from the direction in which the inner shell portion 32 extends. This facilitates the integral molding of the outer peripheral protrusion 34 on the inner shell proximity side and the outer peripheral protrusion 36 on the inner shell separation side by injection molding.

[0019] In addition, it is desirable that the above-described outer structure 22 further includes a plurality of connecting support portions 76, 76 and a support-interconnecting portion 78. The plurality of connecting support portions 76, 76 are respectively connected to the other end of the outer barrel portion 70. The support-interconnecting portion 78 is disposed between the plurality of connecting support portions 76, 76. The support-interconnecting portion 78 is connected to the plurality of connecting support portions 76, 76 so as to face the accommodation space 102. In this case, it is desirable that the plurality of connecting support portions 76, 76 are respectively arranged so as to cross the outer barrel inner circumferential protruding portion 74 when viewed from the direction in which the outer barrel portion 70 extends. Thereby, integral molding by injection molding of the outer barrel inner circumferential protruding portion 74 and the plurality of connecting support portions 76, 76 becomes easy.

[0020] In the present invention, completion of attachment can be easily recognized.

Embodiments for Carrying Out the Invention

[0022] Embodiments of the present invention will be described below with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are the same; therefore, detailed descriptions of them will not be repeated.

[0023] [Configuration of the fixing device] Figure 1 is a perspective view of the fastener 10 according to this embodiment. The configuration of the fastener 10 according to this embodiment will be described based on Figure 1.

[0024] The fastener 10 according to this embodiment is attached to a predetermined object. An example of such a predetermined object is a flat object. An example of such a flat object is the metal plate 200 described later. A well-known long object is attached to the fastener 10 attached to such a predetermined object using a well-known cable tie. The fastener 10 according to this embodiment comprises an inner structure 20 and an outer structure 22.

[0025] In this embodiment, the inner structure 20 adheres to the predetermined object at the time of initial attachment. The outer structure 22 is merely pressed against the object at the time of initial attachment, but gradually becomes firmly attached. As a result, the fastener 10 remains attached to the predetermined object for a long period of time. In addition, as will be clear from the description below, the inner structure 20 can enter the outer structure 22 in this embodiment.

[0026] Figure 2 is a perspective view showing the inner structure 20 according to this embodiment. The configuration of the inner structure 20 according to this embodiment will be described based on Figure 2.

[0027] The inner structure 20 according to this embodiment has an inner attachable portion 30, an inner body portion 32, a plurality of outer peripheral protrusions 34, 34 on the side adjacent to the inner body, and a plurality of outer peripheral protrusions 36, 36 on the side away from the inner body.

[0028] The inner adhesive portion 30 has a flat surface forming portion 110 and a buffer 112. The flat surface forming portion 110 forms a flat surface (not shown). Figure 2 shows the back side of this flat surface (not shown). The back side of this flat surface (not shown) is surrounded by the inner body portion 32. The buffer 112 is adhered to this flat surface (not shown). The buffer 112 in this embodiment is a plate-shaped member made of a softer material than the flat surface forming portion 110. The buffer 112 in this embodiment has an adhesive surface 114. The adhesive surface 114 can adhere to the predetermined object described above. Until immediately before use of the fastener 10 in this embodiment, a well-known protective paper (not shown) is attached to the adhesive surface 114. Multiple slits 154, 154 are formed in the flat surface forming portion 110. In this embodiment, the multiple slits 154, 154 extend radially from the center of the flat surface forming portion 110 and thus the inner adhesive portion 30. The multiple slits 154, 154 are spaced apart from each other. As a result, the portion of the inner adhesive portion 30 surrounded by the multiple slits 154, 154 is integrated at the center of the inner adhesive portion 30. In this embodiment, the specific number of the multiple slits 154, 154 is six.

[0029] As is clear from Figure 2, the inner body portion 32 is connected to the back side of the flat surface forming portion 110, which is not shown above. Therefore, the inner body portion 32 is also connected to the back side of the adhesive surface 114 of the inner adhesive portion 30.

[0030] As is clear from Figure 2, in this embodiment, the inner body portion 32 is cylindrical. Multiple slits 152, 152 are formed on the side of the inner body portion 32 that is connected to the inner adhesive portion 30. Multiple slits 154, 154 formed on the inner adhesive portion 30 are connected to these multiple slits 152, 152 in a one-to-one ratio. In this embodiment, multiple slits 150, 150 are also formed on the end of the inner body portion 32 opposite to the side connected to the inner adhesive portion 30. In this embodiment, the specific number of these multiple slits 150, 150 is also six.

[0031] The outer peripheral protrusion 34 on the side adjacent to the inner casing protrudes at a location closer to the inner attachable portion 30 than the portion of the outer peripheral surface of the inner casing 32 that will be housed in the storage space 102 beforehand. In this embodiment, more specifically, the outer peripheral protrusion 34 on the side adjacent to the inner casing protrudes from three non-adjacent locations among the multiple slits 152, 152 formed on the side of the inner casing 32 that is connected to the inner attachable portion 30. Therefore, the outer peripheral protrusion 34 on the side adjacent to the inner casing protrudes from the locations among the multiple slits 152, 152 that are adjacent to the locations where the outer peripheral protrusion 34 protrudes.

[0032] In this embodiment, the outer peripheral protrusion 36 on the side away from the inner body protrudes at three non-adjacent locations among the multiple slits 150, 150 formed at the end opposite to the side connected to the inner attachable portion 30. Therefore, the outer peripheral protrusion 36 on the side away from the inner body does not protrude from locations adjacent to the locations where the outer peripheral protrusion 36 protrudes among the multiple slits 150, 150. In addition, in this embodiment, the outer peripheral protrusion 36 on the side away from the inner body protrudes is positioned to pass the outer peripheral protrusion 34 on the side adjacent to the inner body when viewed from the direction in which the inner body portion 32 extends.

[0033] Figure 3 is a perspective view showing the outer structure 22 according to this embodiment from one end. The configuration of the outer structure 22 according to this embodiment will be explained based on Figures 1 and 3.

[0034] The outer structure 22 according to this embodiment includes a cylindrical outer body portion 70, an outer attachable portion 72, a plurality of inner circumferential protrusions 74, 74 of the outer body, a plurality of connecting support portions 76, 76, and an inter-support connection portion 78.

[0035] The outer body portion 70 forms a housing space 102. The inner structure 20 is housed in this housing space 102. In this embodiment, the housing space 102 houses a portion of the inner body portion 32 that is separated from the inner attachment portion 30 and the outer peripheral protrusion portion 36 on the inner body separation side.

[0036] The outer adhesive portion 72 is located at one end of the outer body portion 70. The following portion of the outer adhesive portion 72 is capable of adhering to the aforementioned predetermined object. This portion is the portion of the inner body portion 32 that, when a part of it that is away from the inner adhesive portion 30 enters the containment space 102, faces the adhesive surface 114 of the inner adhesive portion 30 in the same space (the portion facing in the same space 90). The opposing point 90 in the same space is on the back side when viewed from the other end of the outer body portion 70.

[0037] The outer casing inner circumferential protrusion 74 extends from the outer casing 70 toward the housing space 102 so as to surround the inner casing 32 at the position described below. This position is closer to one end of the outer casing 70 than the inner casing adjacent outer circumferential protrusion 34 when described below. This is when the aforementioned same-space opposing location 90 is arranged on the same plane as the attachable surface 114. In this embodiment, more specifically, the outer casing inner circumferential protrusion 74 extends from the outer casing 70 at one end of the outer casing 70 and at a position connected to the same-space opposing location 90. In this embodiment, the height of the outer casing inner circumferential protrusion 74 from the inner circumferential surface of the outer casing 70 is a height that satisfies the following two conditions. One of the two conditions is that when the inner casing-adjacent outer periphery protrusion 34 enters the housing space 102, the portion of the inner casing 32 that has not yet entered the housing space 102 can freely pass through the opening formed by one end of the outer casing 70 and the inner casing-inner periphery protrusion 74. The other of the two conditions is that when the inner casing-adjacent outer periphery protrusion 34 enters the housing space 102 formed by the outer casing 70, the inner casing-adjacent outer periphery protrusion 34 comes into contact with the inner casing-inner periphery protrusion 74. In this embodiment, the specific number of these multiple inner casing-inner periphery protrusions 74, 74 is four. In this embodiment, these multiple inner casing-inner periphery protrusions 74, 74 are arranged at equal intervals. In other words, in this embodiment, the specific number of these multiple inner casing-inner periphery protrusions 74, 74 is different from the specific number of inner casing-adjacent outer periphery protrusions 34, 34.

[0038] The multiple connecting support columns 76, 76 in this embodiment are connected to the outer body 70 so as to extend from the other end of the outer body 70 into the housing space 102. As is particularly clear from Figure 3, in this embodiment, the multiple connecting support columns 76, 76 are arranged so as to pass each other with the outer body inner circumferential protrusion 74 when viewed from the direction in which the outer body 70 extends.

[0039] The inter-column connecting section 78 in this embodiment is positioned between a plurality of connecting column sections 76, 76. The inter-column connecting section 78 is connected to the plurality of connecting column sections 76, 76 so as to face the accommodation space 102.

[0040] [Manufacturing method for fastening devices] The manufacturing method of the fastener 10 according to this embodiment has the following steps. The first step is to manufacture the part of the inner structure 20 other than the buffer 112 and the outer structure 22 by known injection molding. The next step is to manufacture the buffer 112 of the inner structure 20 by a known method. In manufacturing the buffer 112, a known adhesive is applied to the adhesive surface 114, and the adhesive is protected by known protective paper. The next step is to bond the part of the inner structure 20 other than the buffer 112 and the buffer 112 of the inner structure 20 by a known method. The next step is to apply a known adhesive to the outer adhesive portion 72 of the outer structure 22. The adhesive is actually applied to the same space facing portion 90. Once the adhesive is applied, a known protective paper is applied to cover the adhesive to protect it. The next step is to house a part of the inner body 32 that is away from the inner adhesive portion 30 in the housing space 102. Once the housing is complete, the fixing device 10 according to this embodiment is finished.

[0041] [How to use the fastening device] The following describes how to use the fastener 10 according to this embodiment. In the following description, the method of use will be explained using the case in which the fastener 10 according to this embodiment is attached to a metal plate 200 as an example. First, the user peels off the protective paper attached to the buffer 112 and the protective paper attached to the same space-opposite location 90 of the outer adhesive portion 72. Once they are peeled off, the user presses the buffer 112 against the metal plate 200 to which the fastener 10 according to this embodiment is attached. Figure 4 is a cross-sectional view showing the fastener 10 according to this embodiment approaching the metal plate 200. When the adhesive surface 114 of the buffer 112 adheres to the metal plate 200, the inner adhesive portion 30 also adheres to the metal plate 200.

[0042] Once the inner adhesive portion 30 adheres to the metal plate 200, the user continues to press the fixing device 10 according to this embodiment against the metal plate 200. As a result, a force is applied to the inner structure 20 in the direction of moving into the accommodating space 102 formed by the outer body portion 70. This force causes relative movement of the inner structure 20 with respect to the outer structure 22.

[0043] As is clear from the above explanation, the portion of the inner body 32 that has not yet entered the housing space 102 can freely pass through the opening formed by one end of the outer body 70 and the inner circumferential protrusion 74 of the outer body. Therefore, when relative movement of the inner structure 20 with respect to the outer structure 22 occurs, the inner structure 20 moves smoothly at the beginning.

[0044] Subsequently, the outer peripheral protrusion 34 on the side closest to the inner barrel comes into contact with the inner peripheral protrusion 74 of the outer barrel. The user continues to press the fastener 10 against the metal plate 200. As a result, the user begins to feel resistance from the fastener 10. Despite feeling resistance, the user continues to press the fastener 10 against the metal plate 200. As a result, the outer peripheral protrusion 34 on the side closest to the inner barrel advances over the area where the inner peripheral protrusion 74 of the outer barrel protrudes. Figure 5 shows the situation in which the outer peripheral protrusion 34 on the side closest to the inner barrel is advancing over the area where the inner peripheral protrusion 74 of the outer barrel protrudes. As the outer peripheral protrusion 34 on the side closest to the inner barrel advances, Figure 5 shows that the inner peripheral protrusion 74 of the outer barrel and the outer peripheral protrusion 34 on the side closest to the inner barrel flex slightly. The dashed line in Figure 5 shows the inner peripheral protrusion 74 of the outer barrel and the outer peripheral protrusion 34 on the side closest to the inner barrel before flexing. When the outer peripheral protrusion 34 on the side adjacent to the inner casing passes over the protruding portion 74 on the inner casing, the inner structure 20, which had been deformed as it passed, returns to its original shape, and the user no longer feels the resistance they had been experiencing. In parallel with this, the outer attachable portion 72 comes into contact with the metal plate 200.

[0045] When the outer peripheral protrusion 34 on the side adjacent to the inner casing passes over the protruding portion 74 on the inner casing, the inner structure 20 no longer protrudes from the outer structure 22. The adhesive surface 114 of the inner structure 20 and the opposing portions 90 in the same space of the outer structure 22 adhere tightly to the metal plate 200. Figure 6 shows the situation where the adhesive surface 114 and the opposing portions 90 in the same space adhere tightly to the metal plate 200. The user leaves the fastener 10 in place until the opposing portions 90 in the same space of the outer structure 22 are firmly adhered to the metal plate 200.

[0046] Once the outer structure 22 is firmly bonded, the user passes a well-known cable tie through the area surrounded by the multiple connecting support sections 76, 76 and the inter-support connection section 78. Once the cable tie has passed through that area, the user uses the cable tie to secure any long object to the fastener 10. This secures the long object to the metal plate 200. The fastener 10 according to this embodiment is used in this manner.

[0047] [Effects of the fastener according to this embodiment] The fastener 10 according to this embodiment allows for easy recognition of the completion of installation. Furthermore, the fastener 10 according to this embodiment prevents excessive resistance to the entry of the outer peripheral protrusion 34 on the side adjacent to the inner body into the housing space 102. Moreover, the fastener 10 according to this embodiment can firmly press against the metal plate 200 or other objects. In addition, the fastener 10 according to this embodiment can be easily integrally molded by injection molding of its components.

[0048] [Explanation of variations] The embodiments disclosed herein are illustrative in all respects. The scope of the present invention is not limited based on the embodiments described above. Of course, various design modifications can be made without departing from the spirit of the invention.

[0049] For example, the specific configuration for passing a well-known cable tie through the outer structure 22 according to this embodiment is not limited to those described above.

[0050] Furthermore, the configuration of the inner adhesive portion 30 is not limited to those described above. For example, the inner adhesive portion may consist only of the flat surface forming portion 110 described above. In that case, the adhesive surface 114 may be provided on the flat surface forming portion 110 to which the buffer body 112 was adhered.

[0051] Furthermore, the specific locations and number of the outer peripheral protrusions 34 on the side adjacent to the inner fuselage and the outer peripheral protrusions 36 on the side further away from the inner fuselage are not limited to those described above. For example, there may be only one of them.

[0052] Furthermore, the end of the inner body portion 32 opposite to the side connected to the inner adhesive portion 30 may be stored in the storage space 102 in advance immediately before use, instead of being replaced during manufacturing. [Explanation of symbols]
