[0014] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the embodiments of the present disclosure are not limited to the following embodiments, and various forms may be adopted as long as they fall within the technical scope of the present disclosure.

[0015] [1. First embodiment] [(1) Overview] A four-wheeled automobile model 1 of the first embodiment is used for wind tunnel testing and includes a plurality of panel members 10 and a framework 12 (see FIG. 1). The model 1 may be the same size as an actual automobile, or may be a scaled-down or scaled-up version of the actual automobile.

[0016] The panel members 10 are resin members that form the outer surface of the model 1, and are formed by a 3D printer. Specifically, each panel member 10 is provided corresponding to a part that constitutes the outer surface of an automobile, such as a bonnet, glass, a front grille, tires, doors, bumpers, etc., of an automobile, and has the shape of the corresponding part.

[0017] The skeleton 12 is a frame-like part arranged inside the model 1. The model 1 is constructed by attaching each panel member 10 to the skeleton 12. An internal space is formed inside the panel members 10 in the model 1. In addition, the skeleton 12 is provided with a base (not shown), and measuring equipment and the like for performing wind tunnel testing are placed on the base. Furthermore, tools used for wind tunnel testing are placed in the internal space.

[0018] Here, the instrument may be, for example, a linear member 13 such as a tube or cable used to measure wind pressure, wind speed, etc. These linear members 13 may be arranged in the internal space in a state where they are bound by an instrument such as a cable clamp 2 (see FIG. 2). An attachment structure 3 to which an instrument such as the cable clamp 2 can be attached is formed on an inner circumferential surface 11 of the panel member 10 that contacts the internal space (see FIGS. 3 to 6).

[0019] [(2) Cable clamp] The cable clamp 2 is made of resin, for example, and includes a band portion 20, a joint portion 21, a cover portion 22, and an anchor clip 23 (see FIG. 2).

[0020] The band portion 20 is a strip-shaped member, and a first end of the band portion 20 is joined to the joining portion 21. The joint 21 is a portion for adjusting the length of the portion of the band part 20 that is used to bundle the linear members 14, etc. In other words, the second end of the band part 20 can be inserted into the joint 21, and the joint 21 can engage with the portion of the band part 20 that passes through the joint 21. Then, by adjusting the engagement position of the band part 20 with the joint 21, the length of the portion of the band part 20 that bundles the linear members 14, etc. can be adjusted.

[0021] The cover portion 22 is a substantially rectangular plate-like portion, and is joined to the band portion 20 . The anchor clip 23 is an example of a mounting portion that is attached to the mounting structure 3, and is joined to the cover portion 22. The anchor clip 23 has a base portion 23A and a head portion 23B.

[0022] The base portion 23A is a cylindrical portion that protrudes from the cover portion 22. Head 23B is a cone-shaped portion provided on the end surface forming the apex of base 23A. That is, the cross section of base 23A and head 23B perpendicular to the protruding direction of base 23A is substantially circular. Also, the peripheral portion of the end face of base 23A in head 23B is thicker than base 23A, and this portion protrudes laterally beyond base 23A over the entire periphery.

[0023] [(3) Mounting structure] The mounting structure 3 is a resin member, and is provided on the inner peripheral surface 11 of the panel member 10 (see FIGS. 2 to 6). The mounting structure 3 includes a support portion 30, a first holding portion 33, and a plurality of (for example, three) second holding portions 35 located on one side of the first holding portion 33.

[0024] The panel member 10 and the entire mounting structure 3 are formed when the panel member 10 is formed by the 3D printer. In other words, the entire mounting structure 3 is not formed by processing the panel member 10 formed by the 3D printer, but is formed integrally with the panel member 10 by the 3D printer.

[0025] The support portion 30 has first and second wall portions 31, 32 (hereinafter also simply referred to as wall portions) which are two substantially rectangular wall-shaped portions. The first and second wall portions 31, 32 are provided so as to protrude from a flat portion of the inner circumferential surface 11 of the panel member 10. The first and second wall portions 31, 32 extend along the direction of an axis A which is a virtual straight line substantially perpendicular to the inner circumferential surface 11, and face each other substantially parallel to each other with the axis A in between.

[0026] The first retaining portion 33 and the multiple second retaining portions 35 are portions for attaching a mounting portion such as the anchor clip 23, and are aligned along the axis A. In other words, these retaining portions are stacked in the direction of the axis A, with the first retaining portion 33 being disposed furthest from the inner circumferential surface 11 of the panel member 10. Furthermore, these retaining portions are aligned so as to overlap with each other at approximately constant intervals, and a similar interval is provided between the inner circumferential surface 11 and the second retaining portion 33 that is closest to the inner circumferential surface 11. Furthermore, these retaining portions are provided on the support portion 30, and are supported by the support portion 30.

[0027] [(4) First holding part] The first holding portion 33 is a substantially square portion extending from the upper end of the first wall portion 31 to the upper end of the second wall portion 32 (see Figs. 3 to 6). The upper end is a portion that forms one side of the substantially rectangular wall portion and is located at the top of the wall portion. The first holding portion 33 extends substantially parallel to a reference plane R, which is an imaginary plane perpendicular to the axis A. The first holding portion 33 has a frame portion 34 and a plurality of holding pieces 4 (eight pieces, for example).

[0028] The frame portion 34 is a frame-shaped portion that forms the outer edge of the first holding portion 33, and is thicker than the holding pieces 4. A substantially circular hole that penetrates the frame portion 34 is formed in the center of the frame portion 34. The axis A passes through approximately the center of the hole. A plurality of holding pieces 4 are disposed in the holes of the frame portion 34.

[0029] The retaining piece 4 is a thin, elastic plate-like portion, and extends from a root portion 41 to a tip portion 40. The root portion 41 is connected to an edge portion surrounding the round hole, and the retaining piece 4 protrudes from the edge portion toward the axis A. Each retaining piece 4 has a substantially identical shape, and the width narrows at a substantially constant rate from the root portion 41 to the tip portion 40. As an example, the shape of the retaining piece 4 is a substantially isosceles triangle, with the root portion 41 forming the base and the tip portion 40 forming the apex angle.

[0030] The multiple holding pieces 4 are arranged so as to be aligned in a circumferential direction (hereinafter simply referred to as the circumferential direction) centered on the axis A. The multiple holding pieces 4 are also arranged so as to extend substantially parallel to the reference plane R, and the tip portion 40 of each holding piece 4 is located around the axis A.

[0031] More specifically, the tip portions 40 of the holding pieces 4 are spaced apart from each other to form a substantially circular gap (central gap S0) around the axis A. The holding pieces 4 are arranged in the circumferential direction with a substantially constant gap (slit S1) between adjacent holding pieces 4. The slits S1 extend radially from the central gap S0 (in other words, the axis A) in a straight line to the frame portion 34. The widths of the slits S1 are substantially the same, and the angles between two adjacent slits S1, in other words, the angles between the slits S1 located on both sides of each holding piece 4 (hereinafter, slit angles) are also substantially the same. These slits S1 extend in the direction of the sides or diagonals of the substantially square first holding portion 33.

[0032] The frame 34 and the multiple holding pieces 4 in the first holding part 33 may be made of different resins, for example, by two-color molding. Specifically, for example, the multiple holding pieces 4 may be made of a resin that is more elastic or flexible than the resin that constitutes the first holding part 33.

[0033] [(5) Second holding part] Each second holding portion 35 is a substantially square portion, has a thin plate shape, and extends from the first wall portion 31 to the second wall portion 32 (see FIGS. 2 to 6). Each second holding portion 35 is located between the first holding portion 33 and the inner circumferential surface 11 of the panel member 10, and extends substantially parallel to the reference plane R. Each second holding portion 35 has an edge portion 36 and a plurality of holding pieces 4 (eight, for example).

[0034] The edge portion 36 is a portion that forms the outer edge of the second holding portion 35, and a plurality of holding pieces 4 are disposed inside the edge portion 36. The holding pieces 4 of the second holding portion 35 have a configuration similar to that of the holding pieces 4 of the first holding portion 33, and a base portion 41 of each holding piece 4 is connected to the edge portion 36. The edge portion 36 and each holding piece 4 have approximately the same thickness.

[0035] Moreover, each holding piece 4 of the second holding portion 35 faces a holding piece 4 of the first holding portion 33 along the direction of the axis A. Moreover, the multiple holding pieces 4 of the second holding portion 35 are arranged similarly to the multiple holding pieces 4 of the first holding portion 33, and a central gap S0 and multiple slits S1 are formed. Moreover, each holding piece 4, central gap S0, and each slit S1 of each second holding portion 35 and each holding piece 4, central gap S0, and each slit S1 of the first holding portion 33 all overlap in the direction of the axis A.

[0036] Moreover, the multiple holding pieces 4 of each second holding portion 35 are arranged so as to extend substantially parallel to the reference plane R. However, this is not limited thereto, and the multiple holding pieces 4 of each second holding portion 35 may be inclined with respect to the reference plane R so as to move away from the first holding portion 33 toward the tip portion 40.

[0037] Note that the edge portion 36 and the multiple holding pieces 4 in the second holding portion 35 may be made of different resins, for example, by two-color molding. Specifically, for example, the multiple holding pieces 4 may be made of a resin that is more elastic or flexible than the resin that makes up the edge portion 36.

[0038] [(6) Installation of mounting parts] As described above, each of the holding parts 33, 35 of the mounting structure 3 is provided with a plurality of holding pieces 4, and the plurality of holding pieces 4 of each holding part are stacked along the axis A (see FIG. 5). Then, the anchor clip 23 is attached to the mounting structure 3 by pushing it toward these holding pieces 4 (see FIG. 2).

[0039] Specifically, when anchor clip 23 is attached, head 23B first comes into contact with multiple holding pieces 4 of first holding portion 33, and then enters inside first holding portion 33. Multiple holding pieces 4 of each holding portion are elastically deformed by pressure via head 23B, and head 23B and base 23A push aside the multiple holding pieces 4 and enter the depths of first holding portion 33.

[0040] The anchor clip 23 can enter the first holding portion 33 until the cover portion 22 comes into contact with the first holding portion 33. When the entire head 23B of the anchor clip 23 enters the inside of the first holding portion 33, the multiple holding pieces 4 of the first holding portion 33 come into contact with the base 23A in an elastically deformed state. Furthermore, each holding piece 4 of the second holding portion 35 through which the anchor clip 23 has passed comes into contact with the base 23A or the head 23B in an elastically deformed state. As a result, the holding pieces 4 are caught by the head 23B around the base 23A, and the anchor clip 23 that has entered the inside of the first holding portion 33 is held.

[0041] Furthermore, the anchor clip 23 held by the multiple holding pieces 4 can be removed from the mounting structure 3 by applying a force of a certain level or more in a direction away from the inner circumferential surface 11 . [2. Second embodiment] [(1) Overview] The mounting structure 3 of the second embodiment has a similar configuration to that of the first embodiment, but differs from that of the first embodiment in the configuration of the holding portion (see FIGS. 7 and 8). The following describes the differences between the mounting structure 3 of the second embodiment and the first embodiment.

[0042] [(2) First holding part] The first holding portion 33 of the second embodiment has a frame portion 34 and a plurality of (eight, for example) holding pieces 4 similar to those of the first embodiment, but differs from the first embodiment in that it is substantially rectangular and in the shapes of the frame portion 34 and the holding pieces 4 (see FIG. 7). Note that the end portions forming the long sides of the first holding portion 33 are connected to the first and second wall portions 31, 32 of the support portion 30.

[0043] The frame portion 34 is a frame-shaped portion similar to that of the first embodiment, but a rectangular hole having a substantially rectangular shape is formed in the center of the frame portion 34. The axis A passes through substantially the center of the rectangular hole. A plurality of holding pieces 4 are arranged in the rectangular hole of the frame portion 34.

[0044] Also, each holding piece 4 of the first holding portion 33 differs from that of the first embodiment in that the shape of each holding piece 4 is a right-angled triangle and that the shapes of each holding piece 4 are different. Moreover, each holding piece 4 is disposed in the same manner as in the first embodiment. However, it differs from the first embodiment in that an elliptical central gap S0 extending along the long side direction is formed around the tip end 40 of each holding piece 4.

[0045] Also, it differs from the first embodiment in that the slit angles of the holding pieces 4 are not always substantially the same. Specifically, two holding pieces 4 are connected to each of a portion forming the long side (hereinafter, long side portion 34A) and a portion forming the short side (hereinafter, short side portion 34B) of the first holding portion 33 in the frame portion 34. The slit angles of the holding pieces 4 of each long side portion 34A are substantially the same, and the slit angles of the holding pieces 4 of each short side portion 34B are also substantially the same. However, the slit angles of the holding pieces 4 of the long side portion 34A are different from the slit angles of the holding pieces 4 of the short side portion 34B.

[0046] [(3) Second holding part] The second holding portion 35 of the second embodiment has an edge portion 36 and a plurality of (eight, for example) holding pieces 4 similar to those of the first embodiment, but differs from the first embodiment in that it is substantially rectangular and in the shapes of the edge portion 36 and the plurality of holding pieces 4 (see FIG. 8). Note that, like the first holding portion 33, the second holding portion 35 also has an end portion forming a long side connected to the first and second wall portions 31, 32.

[0047] That is, in the second embodiment, the multiple holding pieces 4 of the second holding part 35 are configured and arranged similarly to the multiple holding pieces 4 of the first holding part 33. Of course, the central gap S0 and the multiple slits S1 of the second holding part 35 are also configured similarly to the central gap S0 and the multiple slits S1 of the first holding part 35.

[0048] As in the first embodiment, each retaining piece 4, central gap S0, and each slit S1 in each second retaining portion 35 and each retaining piece 4, central gap S0, and each slit S1 in the first retaining portion 33 all overlap in the direction of the axis A.

[0049] Moreover, the multiple holding pieces 4 of each second holding portion 35 are arranged so as to extend substantially parallel to the reference plane R. However, this is not limited thereto, and the multiple holding pieces 4 of each second holding portion 35 may be inclined with respect to the reference plane R so as to move away from the first holding portion 33 toward the tip portion 40.

[0050] [(4) Installation of the mounting part] In the mounting structure 3 of the second embodiment, mounting parts such as anchor clips 23 are attached in the same manner as in the first embodiment (see FIG. 9). However, the mounting structure 3 of the second embodiment is configured to be suitable for attaching an anchor clip 23 having a horizontally elongated shape, that is, an anchor clip 23 having a cone-shaped head portion 23B whose cross section perpendicular to the protruding direction of the base portion 23A has a horizontally elongated shape (for example, an elliptical, oval, or rectangular shape).

[0051] In addition, when attaching the horizontally long anchor clip 23 to the mounting structure 3, it is preferable to attach the anchor clip 23 to the mounting structure 3 with the longitudinal direction of the above-mentioned cross section at the head 23B approximately coinciding with the direction of the long side of the first retaining portion 33.

[0052] [3. Third embodiment] [(1) Overview] The mounting structure 3 of the third embodiment has a similar configuration to that of the first embodiment, but differs from that of the first embodiment in the configuration of the second holding portion 35 (see FIGS. 10 and 11). The following describes the differences between the mounting structure 3 of the third embodiment and the first embodiment.

[0053] [(2) Second holding part] In the third embodiment, the mounting structure 3 is provided with one second holding portion 35 (see Figs. 10 and 11). The second holding portion 35 is provided with an edge portion 36 and a number of holding pieces 4.

[0054] Each of the holding pieces 4 of the second holding portion 35 has a similar configuration to the holding pieces 4 of the first holding portion 33. Similarly to the first embodiment, the edge portion 36 and each of the holding pieces 4 have approximately the same thickness, and the base portion 41 of each of the holding pieces 4 is connected to the edge portion 36. The edge portion 36 is also connected to the first and second wall portions 31, 32, and each of the holding pieces 4 is supported by the first and second wall portions 31, 32 via the edge portion 36.

[0055] Moreover, each of the holding pieces 4 of the second holding portion 35 is disposed so as to overlap with the holding pieces 4 of the first holding portion 33 along the direction of the axis A. Furthermore, the multiple holding pieces 4 of the second holding portion 35 are arranged in a spiral shape in the space between the first holding portion 33 and the inner peripheral surface 11 of the panel member 10. That is, a base line B, which is a spiral imaginary line that goes around the axis A, is set in the space. The base line B is inclined at a certain degree with respect to the reference plane R, and extends from a starting point located near the first holding portion 33 to an end point located near the inner peripheral surface 11. Each holding piece 4 of the second holding portion 35 is arranged in a state inclined with respect to the reference plane R so that a root portion 41 extends along the base line B. Furthermore, each holding piece 4 is inclined with respect to the reference plane R so as to move away from the first holding portion 33 as it approaches the tip portion 40.

[0056] [(3) Modifications] In the mounting structure 3 of the second embodiment, similarly to the third embodiment, one second holding portion 35 having an edge portion 36 and multiple holding pieces 4 may be provided. Similarly, each holding piece 4 of the second holding portion 35 may be disposed in a state inclined with respect to the reference plane R so that the root portion 41 extends along the spiral base line B. Furthermore, each holding piece 4 may be disposed in a state inclined with respect to the reference plane R so that it becomes more distant from the first holding portion 33 as it approaches the tip portion 40.

[0057] [4. Fourth embodiment] [(1) Overview] The mounting structure 3 of the fourth embodiment has a similar configuration to that of the first embodiment, but differs from that of the first embodiment in the configuration of the second holding portion 35 (see FIG. 12). The following describes the differences between the mounting structure 3 of the fourth embodiment and the first embodiment.

[0058] [(2) Second holding part] In the fourth embodiment, similarly to the first embodiment, the mounting structure 3 is provided with a plurality of (for example, three) second holding portions 35 (see FIG. 12). However, the configuration of each second holding portion 35 is different from that of the first embodiment.

[0059] That is, each second retaining portion 35 is disposed approximately parallel to the reference plane R as in the first embodiment, but each second retaining portion 35 is provided on one of the first and second wall portions 31, 32. That is, each second retaining portion 35 is configured such that a portion on the first side or the second side in the second retaining portion 35 of the first embodiment is removed, and this portion is a gap. Note that the first side means the side closer to the first wall portion 31 than the center in the facing direction of the first and second wall portions 31, 32, and the second side means the side closer to the second wall portion 32 than the center.

[0060] The second holding portions 35 provided on the first wall portion 31 and the second holding portions 35 provided on the second wall portion 32 are arranged alternately. The holding pieces 4 and the slits S1 of each second holding portion 35 and the holding pieces 4 and the slits S1 of the first holding portion 33 all overlap in the direction of the axis A.

[0061] Moreover, the multiple holding pieces 4 of each second holding portion 35 are arranged so as to extend substantially parallel to the reference plane R. However, this is not limited thereto, and the multiple holding pieces 4 of each second holding portion 35 may be inclined with respect to the reference plane R so as to move away from the first holding portion 33 toward the tip portion 40.

[0062] [(3) Modifications] In the mounting structure 3 of the second embodiment, similarly to the fourth embodiment, each second retaining portion 35 may be provided on one of the first and second wall portions 31, 32. The multiple retaining pieces 4 of the second retaining portion 35 may be arranged so as to extend substantially parallel to the reference plane R. However, this is not limited thereto, and each of the multiple retaining pieces 4 of the second retaining portion 35 may be inclined with respect to the reference plane R so as to move away from the first retaining portion 33 toward the tip portion 40.

[0063] [5. Effects] (1) According to the above embodiment, the anchor clip 23 can be attached to the mounting structure 3 by pushing the anchor clip 23 of the cable clamp 2 toward the multiple holding pieces 4 of each holding portion stacked along the axis A. In addition, the anchor clip 23 held by the multiple holding pieces 4 can be removed from the mounting structure 3 by applying a force in a direction away from the inner circumferential surface 11. Therefore, the cable clamp 2 can be attached and detached in an appropriate manner.

[0064] (2) In addition, each holding portion is provided with a central gap S0 and multiple slits S1. This allows the anchor clip 23 to be attached to the mounting structure 3 and removed from the mounting structure 3 more smoothly. This allows the cable clamp 2 to be attached and detached more efficiently.

[0065] (3) Furthermore, according to the first, second and fourth embodiments, the multiple holding pieces 4 in each second holding portion 35 are disposed approximately parallel to the reference plane R. Therefore, by applying an appropriate force, the anchor clip 23 can be attached to the mounting structure 3 and the anchor clip 23 held by the multiple holding pieces 4 can be removed. Therefore, the cable clamp 2 can be attached and detached in an appropriate manner.

[0066] (4) According to the above embodiment, each holding piece 4 in each holding portion has a shape in which the width narrows at a substantially constant rate from the base portion 41 to the tip portion 40. According to the first, third and fourth embodiments, each holding piece 4 in each holding portion has substantially the same shape. This allows the cable clamp 2 to be attached and detached in an appropriate manner.

[0067] (5) Furthermore, according to the third embodiment, each holding piece 4 of each second holding portion 35 is inclined with respect to the reference plane R so as to move away from the first holding portion 35 toward the tip portion 40. This allows the anchor clip 23 to be attached to the mounting structure 3 more smoothly, and the anchor clip 23 attached to the mounting structure 3 can be more suitably held. This allows the cable clamp 2 to be more suitably attached and detached.

[0068] (6) Furthermore, while the mounting structure 3 of the above embodiment has a complex structure and is therefore very difficult to mold, according to the above embodiment, the mounting structure 3 and the panel member 10 are integrally formed by a 3D printer. Therefore, the mounting structure 3 can be easily formed.

[0069] 6. Other embodiments (1) In the mounting structure 3 of the above embodiment, the support portion 30 has first and second wall portions 31, 32 protruding from the inner peripheral surface 11 of the panel member 10. However, the configuration of the support portion 30 is not limited to this, and for example, a hole portion may be provided in the inner peripheral surface 11 of the panel member 10, and the support portion may be configured by the inner peripheral surface inside the hole portion. That is, a plurality of holding portions may be provided on the inner peripheral surface of the hole portion in the same manner as in the above embodiment. Also, for example, the support portion may be configured by utilizing a partial region of the inner peripheral surface 11 of the panel member 10. That is, a wall portion may be provided so as to face the region, and the region and the wall portion may be used as the support portion, and a plurality of holding portions may be provided between the region and the wall portion in the same manner as in the above embodiment.

[0070] (2) Furthermore, the mounting structure 3 can be provided not only on a wind tunnel test model, but also on various members formed by a 3D printer. That is, the mounting structure 3 can be formed integrally with these members by a 3D printer. Furthermore, the entire mounting structure 3 may be formed integrally by a 3D printer. Then, the integrally formed mounting structure 3 may be attached to various members.

[0071] (3) In the first, third and fourth embodiments, the holding pieces in each holding portion have substantially the same shape, but the shapes of these holding pieces may be different. In the above embodiment, each holding piece 4 is substantially triangular, and the width narrows at a substantially constant rate from the base portion 41 to the tip portion 40. However, the present invention is not limited to this, and the holding piece 4 may have a shape in which the width narrows at a non-constant rate from the base portion 41 to the tip portion 40, or the width may be substantially constant in some parts. The shape of the holding piece 4 may be determined as appropriate within a range that satisfies the condition that the tip portion 40 is narrower than the base portion 41.

[0072] (4) In the above embodiment, no slit S1 is formed between adjacent holding pieces 4 in the holding portion, and the ends of adjacent holding pieces 4 may be in contact with each other or may overlap each other. Also, although a central gap S0 is formed in each holding portion, the tip ends 40 of the multiple holding pieces 4 in each holding portion may be arranged to be in contact with each other or to overlap each other, so that the central gap S0 is not formed.

[0073] (5) Multiple functions possessed by one component in the above embodiments may be realized by multiple components, or one function possessed by one component may be realized by multiple components. Also, multiple functions possessed by multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Also, part of the configuration of the above embodiments may be omitted. Also, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.
