The light guide bar 2 includes a substantially rectangular columnar main body 21 having a reflection surface 21b and an emission surface 21a of the light LT1 incident from the incident portion 25, and an extension extending laterally from the side surfaces 21c and 21d of the main body portion 21. It has the protrusion parts 23 and 24 and the convex parts 23a and 24a which protruded from the extension parts 23 and 24 further to the side. As shown in FIG. 7C, a plurality of recesses 22 for reflecting the light LT1 incident from the incident portion 25 toward the exit surface 21a are formed on the reflecting surface 21b with an interval in the longitudinal direction D1. ing. A preferable shape of the concave portion 22 is a shape having an inclined surface that reflects the light LT1 incident from the incident portion 25 toward the output surface 21a, such as a cross-sectional groove shape that tapers from the reflective surface 21b toward the inside of the main body portion 21. It is. The convex portions 23 a and 24 a are formed on the extending portions 23 and 24 according to the position where the outer fitting member 4 is attached to the light guide rod 2. In the longitudinal direction D1, the convex portion 23a is longer than the convex portion 24a.

For the light guide rod, a transparent molded product obtained by molding a transparent material by a known method such as injection molding can be used. As the transparent material, a transparent resin material such as acrylic (PMMA) resin, polycarbonate (PC) resin, acrylonitrile butadiene styrene (ABS) resin, or the like can be used. As the light source, an LED (light emitting diode), an incandescent light bulb, or the like can be used, and light sources that emit various colors can be used.
In addition, each surface (surface 21a-21d etc.) of the light-guide rod 2 may be formed not only in a plane but in part or all in a curved surface. Moreover, the light guide rod 2 may have a shape in which a part or all of the light guide rod 2 extends in a curved shape as well as a shape that extends in a straight line.

A rail member 300 (an example of the mating member 3) shown in FIG. 3 and the like includes a slider guide 301, a cable groove 302, a groove 3a in which the light guide rod 2 is accommodated, and the light guide rod 2 in which the outer fitting member 4 is externally fitted. It has an insertion port 3f, regulation walls 305 and 306 (regulation structure 3g), a trim insertion portion 307, and the like.
The slider guide 301 has a groove shape recessed toward the side D5 of the sunshade 5, and guides the inserted slider 6 in the longitudinal direction D1. The cable groove 302 has a groove shape that is further recessed from the bottom 301a of the slider guide 301 to the side D5 so that the slider 6 does not enter, and guides the inserted cable 131 in the longitudinal direction D1.

  The light LT1 from the light guide rod 2 accommodated in the groove 3a is irradiated obliquely upward from the opening 3e of the groove 3a, and illuminates the surface of the closed sunshade 5 on the vehicle interior 101 side. The inner surface 3b of the groove 3a has a bottom 3c on the side opposite to the opening 3e, and a side 3d extending from the bottom 3c to the opening 3e. The side part 3d includes an upper part 303 extending from the upper edge of the bottom part 3c to the opening 3e, and a lower side part 304 extending from the lower edge of the bottom part 3c to the opening 3e. An upper regulating wall 305 is formed at the edge of the upper portion 303 on the opening 3e side so as to be bent downward and to lock the outer fitting member 4 to restrict the light guide rod 2 from falling off. A lower regulating wall 306 is formed at the edge of the lower side portion 304 on the opening 3e side so as to be bent upward to lock the outer fitting member 4 to restrict the light guide rod 2 from falling off. Therefore, both the regulation walls 305 and 306 restrict the light guide rod 2 fitted with the outer fitting member 4 from coming out of the groove 3a in the drop direction D2 different from the longitudinal direction D1 of the light guide rod 2. The trim insertion portion 307 extends from the lower restriction wall 306 in the direction opposite to the bottom portion 3 c and is inserted into a groove of the trim 111 attached to the ceiling interior material 110. Thus, the rail member 300 is fixed to the ceiling interior material 110 via the trim 111. The insertion port 3f connected to the groove 3a is provided on the end surface of the rail member 300 in the longitudinal direction D1. From the insertion port 3f, it is possible to insert the light guide rod 2 with the outer fitting member 4 fitted into the longitudinal direction D1.

  A frame member 320 (an example of the mating member 3) shown in FIG. 4 and the like has no slider guide and cable groove recessed in the drawing direction D6 of the sunshade 5, but has a groove 3a similar to the rail member 300, an insertion port 3f, a restriction wall. 305 and 306 (regulating structure 3g), and a trim insertion portion 307. Since these components exhibit the same function as the rail member 300, description thereof is omitted.

The rail member 300 and the frame member 320 assembled in the automobile are subjected to vibration from the automobile during driving. When the light guide bar is held through the resin housing over the entire length of the grooves of these members 300 and 320, the housing and the light guide bar may be squeezed by vibrations and noise may be generated. In addition, when the rail member 300 and the frame member 320 are made of metal, abnormal noise is easily generated due to the squeezing between the members 300 and 320 and the housing. Therefore, the outer fitting member 4 is partially fitted to the light guide rod 2 in a part in the longitudinal direction, and a gap CL1 is formed between the light guide rod 2 and the counterpart member 3 (rail member 300 and frame member 320). By doing so, the generation of abnormal noise during vibration input is suppressed.
The outer fitting member 4 shown in FIG. 3 or the like is fitted on the light guide rod 2 to form a gap CL <b> 1 between the inner surface 3 b of the groove 3 a of the counterpart member 3 and the light guide rod 2. As shown in FIG. 8 and the like, the outer fitting member 4 includes a base portion 40 facing the bottom portion 3c of the inner side surface 3b, a side portion 50 facing the upper portion 303 of the inner side surface 3b, and a lower side portion 304 of the inner side surface 3b. It has a side part 60 facing the side. A groove 48 surrounding the three sides of the light guide bar 2 is formed in the outer fitting member 4 by these portions 40, 50, 60. The base 40 and the side portions 50 and 60 are inserted into the groove 3a of the mating member 3 and are sized to move in the longitudinal direction D1.

  The outer fitting member 4 may be a molded product such as a synthetic resin injection molded product. As this synthetic resin, thermoplastic resins such as polypropylene (PP) resin, polyacetal (POM) resin, polybutylene terephthalate (PBT) resin, and the like can be used. Additives such as colorants may be added to these resins. The resin outer fitting member 4 has elasticity, and is fitted over the light guide rod 2 by overcoming the convex portions 23 a and 24 a of the light guide rod 2 by elastic deformation.

  As shown in FIG. 5A and the like, the base portion 40 is divided into divided base portions 41 and 42 with a space 43 in the longitudinal direction D1. On the surface of the base 40 that faces the bottom 3c, inclined surfaces 41s and 42s that are separated from the bottom 3c toward the outer side in the longitudinal direction are formed at both ends in the longitudinal direction D1. Here, it is assumed that the inclined surface 41 s is formed on the first divided base 41 and the inclined surface 42 s is formed on the second divided base 42. Since the base 40 has the inclined surfaces 41 s and 42 s, it is easy to insert the light guide rod 2 on which the outer fitting member 4 is fitted from the insertion port 3 f in the longitudinal direction D 1, and the outer fitting member 4 is fitted outside. It is easy to move the light guide rod 2 in the groove 3a.

  From the 1st division | segmentation base 41, the bottom face spring part 4e (example of the spring part 4a) which can be elastically deformed toward the 2nd division | segmentation base 42 protrudes. As shown in FIG. 7A, the bottom spring portion 4e includes a first extension portion 4b extending from the first split base portion 41 in a direction D3 inclined from the longitudinal direction D1 toward the bottom portion 3c of the groove 3a. The first extending portion 4b includes a second extending portion 4c extending from the front end portion 4b1 to the direction D4 inclined from the longitudinal direction D1 to the opposite side to the bottom portion 3c of the groove 3a. Further, a bottom spring portion 4 e (an example of a spring portion 4 a) that can be elastically deformed protrudes from the second divided base portion 42 toward the first divided base portion 41. The bottom spring portion 4e includes a first extension portion 4b extending from the second split base portion 42 in a direction D3 inclined from the longitudinal direction D1 toward the bottom portion 3c of the groove 3a, and a distal end portion of the first extension portion 4b. 4b1 as a starting point, the second extending portion 4c is extended from the longitudinal direction D1 to the direction D4 inclined to the opposite side of the bottom portion 3c of the groove 3a. The angle formed between the tilted direction D3 and the longitudinal direction D1 can be set to about 10 to 30 °, for example. The angle formed between the tilted direction D4 and the longitudinal direction D1 can be, for example, about 10 to 45 °. When the front end 4b1 of the first extending portion 4b of the bottom spring portion 4e of the outer fitting member 4 fitted on the light guide rod 2 contacts the bottom portion 3c of the groove 3a, the bottom spring portion as shown in FIG. An urging force F2 (an example of the urging force F1) in the direction in which 4e pushes the bottom 3c is applied. Therefore, the generation of abnormal noise during vibration input is suppressed. Moreover, since the 1st extension part 4b and the 2nd extension part 4c are extended in the longitudinal direction D1 as a whole, the light guide rod 2 with which the outer fitting member 4 was externally fitted is extended from the insertion port 3f to the longitudinal direction D1. It is easy to insert and it is easy to move the light guide rod 2 with the outer fitting member 4 fitted in the groove 3a.

  Further, arch-shaped contact portions 41 a and 41 b that come out toward the groove 48 and come into contact with the extending portions 23 and 24 of the light guide rod 2 sandwich the main body portion 21 of the light guide rod 2 in the first divided base portion 41. Formed in position. In the second divided base portion 42, arched contact portions 42 a and 42 b that come out toward the groove 48 and contact the extended portions 23 and 24 of the light guide rod 2 are located at positions where the main body portion 21 of the light guide rod 2 is sandwiched. Is formed. Here, the contact portions 41a and 42a are in contact with the extending portion 23, the contact portions 41b and 42b are in contact with the extending portion 24, and a gap is formed between the base portion 40 and the reflecting surface 21b. Since the contact portions 41a, 41b, 42a, and 42b do not press the reflection surface 21b of the light guide bar 2, unevenness of the light LT1 is suppressed.

  The side part 50 includes a first divided side part 51 connected to the first divided base part 41 and a second divided side part 52 connected to the second divided base part 42. The edge part 50e of the side part 50 is connected without being divided. The front end surface 50 f of the side portion 50 extending from the base portion 40 abuts against the upper restriction wall 305 in the groove 3 a of the counterpart member 3. The side part 60 includes a first divided side part 61 connected to the first divided base part 41 and a second divided side part 62 connected to the second divided base part 42. The edge part 60e of the side part 60 is connected without being divided. The front end surface 60 f of the side portion 60 extending from the base portion 40 abuts against the lower restriction wall 306 in the groove 3 a of the counterpart member 3. On the surface facing the upper portion 303 of the side portion 50, the inclined surfaces 51s and 52s that are separated from the upper portion 303 toward the outer side in the longitudinal direction at both ends in the longitudinal direction D1 as shown in FIGS. 6 (a) and 6 (b). Is formed. Here, it is assumed that the inclined surface 51 s is formed on the first divided side portion 51 and the inclined surface 52 s is formed on the second divided side portion 52. In addition, on the surface facing the lower side portion 304 of the side portion 60, the both end portions in the longitudinal direction D1 are inclined away from the lower side portion 304 toward the outer side in the longitudinal direction as shown in FIGS. 6 (a) and 6 (b). Surfaces 61s and 62s are formed. Here, it is assumed that the inclined surface 61 s is formed on the first divided side portion 61 and the inclined surface 62 s is formed on the second divided side portion 62. By having the inclined surfaces 51 s, 52 s, 61 s, 62 s on the side portions 50, 60, it is easy to insert the light guide rod 2 with the outer fitting member 4 fitted into the longitudinal direction D 1 from the insertion port 3 f. The light guide rod 2 on which the member 4 is fitted is easily moved in the groove 3a.

  The side portion 50 is formed with an elastically deformable side surface spring portion 4f (an example of the spring portion 4a) that spans between the first divided side portion 51 and the second divided side portion 52. As shown in FIG. 6A, the side spring portion 4f is a first extension portion extending from the first split side portion 51 in the direction D3 inclined from the longitudinal direction D1 toward the upper portion 303 of the groove 3a. 4b, and a second extension portion 4c extending from the front end portion 4b1 of the first extension portion 4b to the direction D4 inclined from the longitudinal direction D1 to the side opposite to the upper side portion 303 of the groove 3a. Yes. The distal end portion of the second extending portion 4 c is connected to the second divided side portion 52. The angle formed between the inclined direction D3 and the longitudinal direction D1 can be set to about 5 to 20 °, for example. The angle formed between the inclined direction D4 and the longitudinal direction D1 can be set to about 5 to 20 °, for example. When the front end 4b1 of the first extension part 4b of the side spring part 4f of the outer fitting member 4 fitted on the light guide rod 2 contacts the side part 3d of the groove 3a, the side spring as shown in FIG. An urging force F3 (an example of the urging force F1) in a direction in which the portion 4f pushes the side portion 3d is applied. Therefore, the generation of abnormal noise during vibration input is suppressed. Moreover, since the 1st extension part 4b and the 2nd extension part 4c are extended in the longitudinal direction D1 as a whole, the light guide rod 2 with which the outer fitting member 4 was externally fitted is extended from the insertion port 3f to the longitudinal direction D1. It is easy to insert and it is easy to move the light guide rod 2 with the outer fitting member 4 fitted in the groove 3a.

  As shown in FIG. 5B and the like, the first divided side portion 51 is formed with a through hole 51a at a position where the contact portion 41a can be seen from the outside. A through hole 52a is formed in the second divided side portion 52 at a position where the contact portion 42a can be seen from the outside. Between these holes 51a and 52a and between the side spring portion 4f and the edge portion 50e, an engagement hole 53 into which the convex portion 23a of the light guide rod 2 is inserted is formed as a through hole. .

  As shown in FIG. 5A and the like, the side portion 60 is formed with a bridging portion 66 that spans between the first divided side portion 61 and the second divided side portion 62. A through hole 61a is formed in the first divided side portion 61 at a position where the contact portion 41b can be seen from the outside. A through hole 62a is formed in the second divided side portion 62 at a position where the contact portion 42b can be seen from the outside. Between these holes 61a and 62a and between the bridging portion 66 and the edge portion 60e, an engagement hole 63 into which the convex portion 24a of the light guide rod 2 is inserted is formed as a through hole. Since the convex portion 23a which is longer in the longitudinal direction D1 than the convex portion 24a in the light guide rod 2 does not enter the engagement hole 63, the outer fitting member 4 attached to the light guide rod 2 can be in the same direction. On the first divided side portion 61, a convex portion 64 is formed in the vicinity of the engagement hole 63. A convex portion 65 is formed in the vicinity of the engagement hole 63 in the second divided side portion 62. These convex parts 64 and 65 are designed to contact the lower part 304 of the groove 3a together with the edge part 60e.

(4) Formation method, operation, and effect of light guide rod holding structure:
The light guide rod holding structure 1 described above can be formed as follows, for example.
First, the external fitting member 4 is externally fitted to the light guide rod 2 in accordance with the positions of the convex portions 23 a and 24 a of the light guide rod 2. For example, the groove 48 of the outer fitting member 4 is directed to the reflection surface 21b of the light guide rod 2, the convex portion 23a of the light guide rod 2 is inserted into the engagement hole 53 of the outer fitting member 4, and the light guide rod 2 is fitted. When pushed into the groove 48 of the member 4, the outer fitting member 4 is elastically deformed and the convex portion 24 a of the light guide rod 2 is inserted into the engagement hole 63 of the outer fitting member 4. In this way, as shown in FIG. 2, the plurality of external fitting members 4 are externally fitted to the light guide rod 2 at intervals in the longitudinal direction D <b> 1. Each outer fitting member 4 is engaged with the convex portions 23 a and 24 a of the light guide bar 2 in the engagement holes 53 and 63, so that it does not come off from the light guide bar 2 and is longitudinal with respect to the light guide bar 2. Does not move to D1. Thus, the light guide rod 2 in which each outer fitting member 4 is fitted is prepared for the pair of rail members 300 and the frame member 320, respectively.

  Next, the light guide rod 2 in which the outer fitting member 4 is partially fitted is inserted from the insertion port 3f of the mating member 3 into the groove 3a in the longitudinal direction D1. As described above, the inclined surfaces 41 s, 42 s, 51 s, 52 s, 61 s, 62 s are formed on the outer fitting member 4, and the first extending portion 4 b and the second extending portion 4 c included in the spring portion 4 a are longitudinal as a whole. It extends in the direction D1. Accordingly, the light guide rod 2 with the outer fitting member 4 fitted outside can be easily inserted in the longitudinal direction D1 from the insertion port 3f, and the light guide rod 2 with the outer fitting member 4 fitted outside is inserted into the groove 3a. It can be easily moved in the longitudinal direction D1. In this way, the light guide bar holding structure 1 is formed. Of course, the light guide rod 2 with the outer fitting member 4 fitted into each of the pair of rail members 300 and the frame member 320 is inserted.

  The pair of rail members 300 and the frame member 320 on which the light guide bar holding structure 1 is formed are fixed to the ceiling interior material 110 via the trim 111 as shown in FIGS. When the sunshade 5 shown in FIG. 1 is pulled out from the winding mechanism 120 and the opening 112 is closed with the sunshade 5 and the light source 10 as shown in FIG. 2 is turned on, the light guide rod 2 housed in the groove 3 a of the counterpart member 3. The light LT1 from the light exits from the groove 3a and illuminates the surface of the closed sunshade 5 on the vehicle interior 101 side as shown in FIG. Here, since the pair of rail members 300 are arranged on the left and right of the opening 112 and the frame member 320 is arranged in front of the opening 112, the left edge of the opening 112 in the sunshade 5 that can be seen from the opening 112. The strip, the right edge, and the strip-shaped portion along the front edge are illuminated. Thus, the sunshade 5 of the passenger compartment ceiling 102 is illuminated in a strip shape along the edge of the opening 112, so that a good design is produced on the ceiling 102.

  In the light guide rod holding structure 1, the light guide rod 2 with the outer fitting member 4 fitted therein can be inserted into the insertion port 3f of the counterpart member 3 in the longitudinal direction D1, and the outer fitting member 4 is fitted over the groove 3a. The light guide rod 2 accommodated in the member 3 is restricted from coming out of the groove 3a in the drop-off direction D2 by the restriction structure 3g of the counterpart member 3. For this reason, a member such as a resin clip for attaching the outer fitting member 4 to the mating member 3 is unnecessary, and a member such as a cover molding that covers the light guide rod 2 on which the outer fitting member 4 is externally fitted is also unnecessary. Therefore, the light guide bar holding structure 1 requires fewer members for holding the light guide bar, leading to a reduction in component costs. Further, as disclosed in Japanese Patent Application Laid-Open No. 2008-132807, it is not necessary to surround the light guide with a long housing extending over the entire length of the mounting groove, leading to a reduction in material costs.

  Furthermore, even if the light guide rod holding structure 1 is incorporated in the metal counterpart member 3 that is likely to generate abnormal noise, the spring portion 4a of the outer fit member 4 fitted on the light guide rod 2 is a groove of the counterpart member 3. Since the urging force F1 in the pushing direction is applied to the inner surface 3b of 3a, the generation of abnormal noise during vibration input is suppressed. In particular, since the direction of the urging force F2 by the bottom surface spring portion 4e is different from the direction of the urging force F3 by the side surface spring portion 4f, the generation of abnormal noise during vibration input is preferably suppressed.
