  The clip according to the embodiment of the present invention is not a configuration including a simple clip portion, a skirt portion, a holding portion, etc., but a configuration in which the skirt portion is divided into a plurality of annular bodies with respect to the axial direction of the skirt portion. The annular bodies adjacent to each other are connected to each other so as to be rotatable in the axial direction of the skirt portion via a connecting portion provided between the annular bodies.

  Here, the known technique will be described with reference to the drawings. For example, as shown in the clip 100 shown in FIG. 5, the clip portion 1 having the fitting hole 11 that fits the protruding tip portion 41 of the column 4 such as a stud bolt, A cylindrical skirt portion 2 that extends from the opening edge of the fitting hole 11 of the clip portion 1 in the opening direction of the fitting hole 11 and covers the outer peripheral side between the tip portion 41 and the root portion 42 of the support column 4. And a holding part 3 that protrudes from the clip part 1 or the skirt part 2 to the outer peripheral side and holds the object to be held (not shown) is known.

  In this known clip 100, when the combination with the support column 4 is suitable, for example, the fitting hole 11 (bottom wall surface 11a) in the clip 100 and the skirt portion 21 (the skirt portion 21 side) are formed in the skirt portion 2. L1 is a dimension between the base part 42 and the tip part 41 of the support column 4 (hereinafter referred to as a support column dimension) L2. In the case of L1 = L2 that is coincident (or substantially coincident), the support 4 is covered with the clip 100 from the front end portion 41 side, so that the skirt portion 21 of the skirt portion 2 is shown in FIG. Is engaged (or substantially engaged) with the peripheral portion of the base portion 42 of the support column 4 and is supported in a state where the tip end portion 41 of the support column 4 is fitted in the fitting hole 11 of the clip portion 1. .

  However, when the combination of the clip 100 and the support column 4 is incompatible, for example, when L1> L2 in which the in-clip dimension L1 is larger than the support column dimension L2, the skirt portion 21 is the root portion as shown in FIG. Although it engages with the peripheral edge of 42, it will be in the state which the front-end | tip part 41 of the support | pillar 4 removed from the fitting hole 11, and the support structure of the clip 100 will become unstable. In this case, since the outer peripheral side of the support column 4 is covered by the skirt portion 2, it is difficult to check the above-mentioned detached state.

  Further, in the case where L1 <L2 in which the in-clip dimension L1 is smaller than the support column dimension L2, the tip portion 41 of the support column 4 is fitted into the fitting hole 11 as shown in FIG. A gap is formed between the base portion 42 and the peripheral portion of the root portion 42, and the suspension structure is suspended, and the support structure of the clip 100 becomes unstable as in FIG. If the suspended state is, for example, from the horizontal direction side (for example, the left-right direction side in the figure) with respect to the gap, there is a possibility that it can be confirmed by visual observation or the like, but it is closer to the clip portion 1 side than the horizontal direction. It is difficult to confirm from the position (position in the upward direction in the figure).

  On the other hand, in the clip of the present embodiment, among the annular bodies of the skirt portion, the annular bodies adjacent to each other are connected so as to be rotatable in the axial direction of the skirt portion, so that the above L1> L2 and L1 <When the combination with the support is incompatible as in L2, at least a part of each annular body is rotated so that the shape of the skirt portion can be deformed. The deformed state of the skirt portion can be easily confirmed visually or the like as compared with the case where the clip 100 is not suitable as shown in FIG.

  In addition, when the combination of the pillars in the clip of this embodiment is suitable, the annular bodies are overlapped and integrated to form a skirt portion having a desired shape, and the outer peripheral side of the pillar is covered by the skirt portion. be able to. At this time, the bottom part of the skirt is engaged (or substantially engaged) with the peripheral part of the base part of the support column, and the tip end of the support column is fitted into the fitting hole of the clip unit. Is stable.

  As described above, according to the clip of the present embodiment, it is easy to determine whether the combination of the support column and the clip is suitable or non-conforming. For example, in the case of the non-conformity, the clip can be quickly replaced with a conforming clip. This also contributes to clip mounting workability.

  As described above, the clip of the present embodiment only needs to have a skirt portion having a configuration having a plurality of annular bodies, and is generally used in various fields such as the automobile field, the clip field, the electric wire field, and the hinge field. It is possible to make appropriate changes by applying known techniques.

<Clip part>
The clip portion is appropriately formed according to the shape of the tip end portion of the support column to be fitted, and has a fitting hole in which the tip end portion of the support column is fitted when the support column is covered with the clip. It should be. In this fitting hole, for example, as shown in Patent Document 1, there is a configuration in which it is detachably fitted to the tip end portion of the support column. When the support column is a bolt having a thread or the like, it is formed on the inner wall of the engagement hole. A claw-like lock may be formed, and the lock may be detachably engaged with the screw thread. According to this lock, for example, even if an unexpected pulling force acts on the clip, it is possible to suppress the fitting hole and the tip end portion of the support from being easily detached (Patent Document 1). Descriptions according to claims 4 and 5 and paragraphs [0037] and [0038]).

<Skirt part>
The skirt portion is a cylindrical shape that extends from the opening edge of the fitting hole of the clip portion in the opening direction of the fitting hole and can cover the outer peripheral side of the support column, and each skirt portion is configured as described above. The annular bodies adjacent to each other among the annular bodies are connected to each other so as to be rotatable in the axial direction of the skirt part via the connecting part, and the skirt parts of a desired shape are formed by overlapping each other and integrating them. Anything that can be done.

  The connecting portion is not particularly limited as long as the adjacent annular bodies can be rotatably connected to each other. For example, various hinges that can be provided between the annular bodies on the outer peripheral surface of the skirt portion are applied. To do. Moreover, a connection part can be provided in the arbitrary positions between each annular body. When the skirt portion has a large number (three or more) of annular bodies, the connecting portions between the annular bodies are positioned on a straight line along the axial direction of the skirt portion on the outer peripheral surface of the skirt portion. You may provide, and you may provide so that it may mutually oppose and may be located. In particular, when the number of annular bodies is large, it is easy to keep the center of gravity of the skirt part (particularly the location of each annular body) in a well-balanced manner by providing the connecting portions so as to be alternately opposed as described above. (For example, the center of gravity can coincide with or be close to the axial center of the skirt portion), which contributes to clip mounting workability.

  Each annular body has an annular shape so as to surround the outer peripheral side of each support column, and each of the annular bodies overlaps in a step-by-step manner to form a skirt portion. It is not limited, and it is possible to design suitably according to the support | pillar and to-be-held object which are fitting objects.

  Further, in the skirt portion, for example, as shown in FIGS. 5 and 6, an opening (reference numeral 22 in FIGS. 5 and 6) penetrating in the axial direction is formed in the skirt portion of the skirt portion. It may be configured such that the tip of the support can be inserted into the part, but a slit having a slit width larger than the radial width of the support and penetrating the outer peripheral side and the inner peripheral side of the skirt part is provided on the skirt part. The structure formed so that it might extend in the axial direction from a skirt part may be sufficient. As a result, in the work of covering the strut with the clip, it can be performed while guiding the front end of the strut along the slit to the fitting hole side in the skirt, and the front end of the strut and the fitting hole are fitted. It becomes easy to do. That is, the slit functions as a fitting guide, which contributes to clip mounting workability.

<Support>
The support column is appropriately installed according to the holding position of the object to be held (for example, a predetermined routing route), and the tip end portion of the support column is fitted in the fitting hole of the clip to support the clip. For example, various bolts can be used as support columns, and specific examples include the use of stud bolts that can be projected on a vehicle body panel or the like, or bolts that are assembled on vehicle equipment (batteries, etc.). The installation position and the like are not particularly limited.

<Holding part>
The holding part may have any structure as long as it can hold a target object to be held. For example, the holding part holds a wire such as a wire harness and extends along the wiring path of the wire (in the examples described later). (Holding part with L-shaped cross section), and fixed to each other with adhesive tape, band clip, etc. (for example, by winding both with adhesive tape) in a state where electric wires are stacked in bundles on this holding part However, the holding structure is not particularly limited. Further, it may be formed on either the clip portion or the skirt portion of the clip, and specific examples include a configuration formed so as to protrude from the clip portion or the skirt portion to the outer peripheral side.

<Holded object>
The object to be held may be any object that can be held by the holding part of the clip, and examples thereof include various electric wires such as a wire harness and a battery cable applied to the vehicle body, but are not particularly limited.

<Others>
The clip can be manufactured by various methods, for example, a method of integrally forming each part of the clip part, the skirt part, and the holding part by molding, but welding after forming each part separately For example, a method of integrating them may be used. As a specific example, in the case of a skirt portion, the entire skirt portion is previously formed by molding or the like, and then the skirt portion is divided by cutting or the like so as to form a plurality of annular bodies in the axial direction. There is a method in which a connecting portion is provided between each annular body and each is connected so as to be rotatable.

  Next, although an example of the clip in the present embodiment will be described based on the following examples, the present invention is not limited to these. In the following embodiments, the same reference numerals are used for the same components as those in FIGS. 5 and 6, and the detailed description thereof is omitted.

<Example 1>
The clip 10a of FIG. 1 has a substantially cap-shaped clip portion 1, and is a cylindrical shape that extends from the opening edge of the fitting hole 11 of the clip portion 1 in the opening direction of the fitting hole 11 and has a transverse cross section. The shape (radial cross-sectional shape) is a rectangular shape and includes a skirt portion 20 that covers the outer peripheral side of the support column 4 from four directions. The skirt portion 20 is divided into two parts in the axial direction, and has an annular body 23 located on the clip 1 side and an annular body 24 located on the skirt 21 side.

  A hinge 25 is provided between one end edges of one of the four sides of the annular bodies 23 and 24. Via the hinge 25, the annular bodies 23 and 24 are connected so as to be rotatable with respect to the axial direction of the skirt portion 20. The annular body 23 is provided with a holding portion 3 having a substantially L-shaped cross section so as to extend from the annular body 23 toward the outer peripheral side. In the annular body 24, a slit 26 having a slit width larger than the radial width of the support column 4 and penetrating the outer peripheral side and the inner peripheral side of the skirt portion 20 extends in the axial direction from the skirt portion 21 of the skirt portion 20. It is formed to extend. In the first embodiment, the skirt portion 21 side of the slit 26 is formed so as to penetrate from the outer peripheral side of the skirt portion 20 to the axial center side.

  The clip 10a configured as described above is used by covering the support column 4 in the order shown in FIGS. 1A to 1C, for example. First, as shown in FIGS. 1A and 1B, the tip end portion 41 of the support column 4 is inserted into the skirt portion 20 from the slit 26 of the skirt portion 20 (for example, the skirt portion 21 side of the slit 26). Then, the clip 10 a is covered with the support column 4. Thereby, the front-end | tip part 41 is guided to the fitting hole 11 side along the axial center direction of the skirt part 20. As shown in FIG. And the front-end | tip part 41 of the said support | pillar 4 inserted is fitted in the fitting hole 11, and the skirt | skirt part 21 of the skirt part 20 is the root part 42 of the support | pillar 4 as shown in FIG.1 (C), (D). It will be engaged with the peripheral edge side.

  Here, when the combination of the clip 10a and the support column 4 is incompatible, the shape of the skirt portion 20 is deformed as shown below, for example. First, when the in-clip dimension L1 and the pillar longitudinal dimension L2 of the pillar 4 are L1> L2, the skirt 21 side of the annular body 24 is the peripheral edge of the root part 42 of the pillar 4 as shown in FIG. The annular body 23 is rotatable in the axial direction of the skirt portion 20 while being engaged with each other. In the case of L1 <L2, as shown in FIGS. 2B and 2C, the tip end portion 41 of the support column 4 is fitted into the fitting hole 11 of the clip portion 1 so that the annular body 23 is fixed. However, the annular body 23 is rotatable in the axial direction of the skirt portion 20.

  By confirming the skirt portion 20 deforming in this way by visual observation or the like, it is possible to easily determine whether the combination of the clip 10a and the support column 4 is appropriate or not. Moreover, since each annular body 23, 24 rotates as described above, a portion other than the hinge 25 between each of the annular bodies 23, 24 is expanded, so that the inside of the skirt portion 20 is extended from the expanded portion. It is also possible to confirm.

<Example 2>
The clip 10b of FIG. 3 is a modification of the clip 10a shown in FIG. 1, and is configured by further dividing the annular body 24 positioned on the skirt portion 21 side into a plurality of portions in the axial direction of the skirt portion 20a. That is, it has a configuration having a plurality of thin plate-like annular bodies 27 (five in FIG. 3). The annular bodies 27 are provided so that the hinges 25 between the annular bodies 27 are alternately positioned opposite to each other so that the adjacent annular bodies 27 can be rotated and folded in a twisted manner. It is connected and configured.

  In the second embodiment, the hinges 25 provided between the annular bodies 27 are each composed of a pair of hinge members 28 a and 28 b, and the hinge members 28 a and 28 b are larger than the radial width of the column 4. It is comprised so that it may be located apart. Further, the inner peripheral side 29 of each annular body 27 is formed into a slit shape extending in a direction orthogonal to the space between the hinge members 28a and 28b in the radial direction of the annular body 27, that is, a pair of inner wall surfaces are mutually connected. It is shaped so as to extend in the radial direction of the annular body 27 with a distance larger than the radial width of the support column 4, and penetrates the outer peripheral side of the annular body 27 in the extending direction. Thereby, when each annular body 27 is overlapped in a distorted manner, a slit 26 extending in the axial direction from the skirt portion 21 of the skirt portion 20 is formed. Therefore, in the second embodiment, the inner peripheral side 29 of each annular body 27 becomes a part of the slit 26, and each has a function as a fitting guide.

  The clip 10b configured in this way is used by covering the support column 4 in the order shown in FIGS. 3A to 3C, for example. First, as shown in FIGS. 3A and 3B, the tip 41 of the support column 4 is inserted into the skirt 20 from the slit 26 of the skirt 20 (for example, the skirt 21 side of the slit 26). In other words, the clip 10 b is covered with the support column 4 so as to be inserted from the slit-like inner peripheral side 29 (each inner peripheral side 29 which is a part of the slit 26) in each annular body 27. Thereby, the front-end | tip part 41 is guided to the fitting hole 11 side along the axial center direction of the skirt part 20. As shown in FIG. As shown in FIGS. 3C and 3D, the tip 41 of the inserted support column 4 is fitted into the fitting hole 11, and the annular bodies 27 overlap each other in a distorted manner. The 20 hem portions 21 are engaged with the peripheral side of the base portion 42 of the support column 4.

  Here, when the combination of the clip 10b and the support column 4 is incompatible, the shape of the skirt portion 20 is deformed as shown below, for example. First, when the in-clip dimension L1 and the pillar longitudinal dimension L2 of the pillar 4 are L1> L2, as shown in FIG. 4A, the annular body 27 located on the skirt 21 side of each annular body 27 is Each annular body 27 and the annular body 23 are rotatable in the axial direction of the skirt portion 20 while being engaged with the peripheral edge portion of the base portion 42 of the support column 4. When L1 <L2, as shown in FIGS. 4B and 4C, the tip end portion 41 of the support column 4 is fitted into the fitting hole 11 of the clip portion 1 to fix the annular body 23. However, each annular body 27 is in a state of being rotatable in the axial direction of the skirt portion 20.

  By confirming the skirt portion 20 deforming in this way by visual observation or the like, it is possible to easily determine whether the combination of the clip 10b and the column 4 is suitable or not. Further, since the annular body 23 and each annular body 27 are rotated as described above, a portion other than the hinge 25 between the annular bodies 23 and 27 is expanded, so that the skirt portion 20 is extended from the expanded portion. It is also possible to check the interior of the.

  Although the present invention has been described in detail only for the specific examples described above, it is obvious to those skilled in the art that various modifications can be made within the scope of the technical idea of the present invention. It is natural that such changes and the like belong to the scope of the claims.
