  The light guide rod holding structure 1 includes the light guide rod 2, the mating member 3, and the outer fitting member 4.

  The light guide rod 2 is a long light guide, and is accommodated in the groove 3 a of the opposing member 3 with the longitudinal direction D 1 aligned with the opposing member 3. The end face in the longitudinal direction D1 of the light guide rod 2 shown in FIG. 2 and the like is an incident portion 25 on which the light from the light source 10 is incident. The light guide rod 2 is a substantially square prism-shaped main body 21 having a reflection surface 21b and an emission surface 21a of the light LT1 incident from the incident part 25, and a side extending from the side surfaces 21c and 21d of the main body 21. It has protrusion parts 23 and 24 and convex parts 23 a and 24 a further protruding laterally from the extension parts 23 and 24. As also shown in FIG. 7C, a plurality of recesses 22 for reflecting the light LT1 incident from the incident portion 25 toward the emission surface 21a are formed on the reflection surface 21b at intervals in the longitudinal direction D1. ing. The preferred shape of the recess 22 is a groove having a cross section which is tapered from the reflective surface 21b toward the inside of the main body 21 and having an inclined surface for reflecting the light LT1 incident from the incident portion 25 toward the output surface 21a It is. The protruding portions 23 a and 24 a are formed in the extending portions 23 and 24 in accordance with the position where the outer fitting member 4 is attached to the light guide rod 2. The protrusion 23a is longer than the protrusion 24a in the longitudinal direction D1.

For the light guide rod, a transparent molded product or the like obtained by molding a transparent material by a known method such as injection molding can be used. As the transparent material, a resin material having transparency such as acrylic (PMMA) resin, polycarbonate (PC) resin, and acrylonitrile butadiene styrene (ABS) resin can be used. As a light source, an LED (light emitting diode), an incandescent lamp, or the like can be used, and a light source emitting various colors can be used.
In addition, each surface (surface 21a-21d etc.) of the light guide stick 2 may be formed in a curved surface not only a plane but part or all. Further, the light guide rod 2 may have not only a linearly extending shape, but also a shape in which a part or the whole thereof extends in a curvilinear shape.

The rail member 300 (example of the mating member 3) shown in FIG. 3 etc. is a slider guide 301, a cable groove 302, a groove 3a in which the light guiding rod 2 is accommodated, and a light guiding rod 2 in which the outer fitting member 4 is externally fitted. It has an insertion port 3f, restricting walls 305 and 306 (regulating structure 3g), a trim inserting portion 307, and the like.
The slider guide 301 is in the shape of a groove recessed to the side D5 of the sunshade 5, and guides the inserted slider 6 in the longitudinal direction D1. The cable groove 302 is in the form of a groove recessed from the bottom portion 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 housed in the groove 3a is irradiated obliquely upward from the opening 3e of the groove 3a, and illuminates the surface of the sunshade 5 in the closed state on the vehicle room 101 side. The inner surface 3b of the groove 3a has a bottom 3c opposite to the opening 3e, and a side 3d from the bottom 3c to the opening 3e. The side 3d includes an upper portion 303 extending from the upper edge of the bottom 3c to the opening 3e and a lower portion 304 extending from the lower edge of the bottom 3c to the opening 3e. At the edge on the opening 3 e side of the upper side portion 303, an upper restricting wall 305 is formed which is bent downward and locks the outer fitting member 4 to restrict the light guiding rod 2 from falling off. At the edge of the lower side 304 on the side of the opening 3e, a lower regulating wall 306 is formed which is bent upward to lock the outer fitting member 4 so as to restrict the light guiding rod 2 from falling off. Therefore, both of the restriction walls 305 and 306 restrict the light guide rod 2 with the outer fitting member 4 being externally fitted out from the groove 3 a in the dropping direction D2 different from the longitudinal direction D1 of the light guide rod 2. The trim insertion portion 307 extends from the lower regulating wall 306 in the opposite direction to the bottom 3 c and is inserted into the 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 3 f connected to the groove 3 a is provided on the end surface of the rail member 300 in the longitudinal direction D 1. From the insertion port 3f, it is possible to insert the light guide rod 2 on which the outer fitting member 4 is externally fitted in the longitudinal direction D1.

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

During operation, vibrations are applied to the rail member 300 and the frame member 320 assembled to the vehicle during driving. When the light guide bar is held through the resin housing over the entire length of the groove of these members 300 and 320, the housing and the light guide bar may be cracked due to vibration, and abnormal noise may be generated. Further, when the rail member 300 and the frame member 320 are made of metal, abnormal noise is likely to be generated due to the members 300 and 320 and the housing being squeezed. Therefore, the outer fitting member 4 is partially fitted to a part of the light guide rod 2 in the longitudinal direction to form a clearance CL1 between the light guide rod 2 and the counterpart member 3 (the rail member 300 and the frame member 320) By doing this, abnormal noise generation at the time of vibration input is suppressed.
The outer fitting member 4 shown in FIG. 3 and the like is externally fitted to the light guide bar 2 to form a clearance CL 1 between the inner side surface 3 b of the groove 3 a of the mating member 3 and the light guide bar 2. As shown in FIG. 8 and the like, the outer fitting member 4 has a base 40 facing the bottom 3c of the inner side 3b, a side 50 facing the upper side 303 of the inner side 3b, and a lower side 304 of the inner side 3b. And the side 60 facing. Grooves 48 surrounding three sides of the light guide rod 2 are formed in the outer fitting member 4 by these portions 40, 50, 60. The base 40 and the side portions 50, 60 are sized to be inserted into the groove 3a of the mating member 3 and movable in the longitudinal direction D1.

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

  As shown in FIG. 5A and the like, the base 40 is divided into divided base portions 41 and 42 across the space 43 in the longitudinal direction D1. In the surface facing the bottom 3c of the base 40, sloped surfaces 41s and 42s are formed at both ends in the longitudinal direction D1 so as to be apart from the bottom 3c as it goes to the outside in the longitudinal direction. Here, 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. With the inclined surfaces 41s and 42s in the base 40, the light guide rod 2 to which the externally fitted member 4 is externally fitted can be easily inserted from the insertion opening 3f in the longitudinal direction D1, and the externally fitted member 4 is externally fitted. It is easy to move the light guide rod 2 in the groove 3a.

  From the first divided base portion 41, a bottom surface spring portion 4e (example of the spring portion 4a) which can be elastically deformed protrudes toward the second divided base portion 42. The bottom spring portion 4e is, as shown in FIG. 7A, a first extension portion 4b extending from the first divided base portion 41 in the direction D3 inclined from the longitudinal direction D1 toward the bottom 3c of the groove 3a. It has the 2nd extension part 4c extended in the direction D4 which inclined to the opposite side to bottom part 3c of slot 3a from longitudinal direction D1 from tip part 4b1 of this 1st extension part 4b as a starting point. Further, from the second divided base portion 42, a bottom surface spring portion 4e (example of the spring portion 4a) which can be elastically deformed protrudes toward the first divided base portion 41. The bottom spring portion 4e is a first extension 4b extending from the second divided base 42 in the direction D3 which is inclined from the longitudinal direction D1 toward the bottom 3c of the groove 3a, and the tip of the first extension 4b It has the 2nd extension part 4c extended in the direction D4 which inclined to the opposite side to the bottom part 3c of slot 3a from longitudinal direction D1 from 4b1 as a starting point. The angle between the inclined direction D3 and the longitudinal direction D1 can be, for example, about 10 to 30 degrees. The angle between the inclined direction D4 and the longitudinal direction D1 may be, for example, about 10 to 45 degrees. The bottom spring portion 4b1 of the first extension 4b of the bottom spring portion 4e of the outer fitting member 4 externally fitted to the light guide rod 2 contacts the bottom 3c of the groove 3a, as shown in FIG. The biasing force F2 (example of biasing force F1) in the direction in which 4e pushes the bottom 3c is applied. Therefore, the generation of abnormal noise at the time of vibration input is suppressed. Further, since the first extending portion 4b and the second extending portion 4c extend in the longitudinal direction D1 as a whole, the light guide rod 2 with the outer fitting member 4 externally fitted is moved from the insertion opening 3f to the longitudinal direction D1. It is easy to insert, and it is easy to move the light guide rod 2 on which the outer fitting member 4 is externally fitted in the groove 3a.

  Furthermore, arched contact portions 41 a and 41 b coming out toward the groove 48 and contacting the extension portions 23 and 24 of the light guide bar 2 sandwich the main body portion 21 of the light guide bar 2 in the first divided base 41. It is formed in position. In the second divided base portion 42, arched contact portions 42a and 42b coming out toward the groove 48 and coming into contact with the extension portions 23 and 24 of the light guide rod 2 sandwich the main body portion 21 of the light guide rod 2 It is formed. Here, the contact portions 41a and 42a contact the extension portion 23, the contact portions 41b and 42b contact the extension portion 24, and a gap is formed between the base 40 and the reflective surface 21b. Since the contact portions 41a, 41b, 42a, 42b do not press the reflection surface 21b of the light guide rod 2, unevenness of the light LT1 is suppressed.

  The side 50 includes a first divided side 51 connected to the first divided base 41 and a second divided side 52 connected to the second divided base 42. The edge 50e of the side 50 is connected without being divided. The front end surface 50 f of the side portion 50 extending from the base 40 abuts on the upper restriction wall 305 in the groove 3 a of the mating member 3. The side 60 includes a first divided side 61 connected to the first divided base 41 and a second divided side 62 connected to the second divided base 42. The edge 60e of the side portion 60 is connected without being divided. The front end surface 60 f of the side portion 60 extending from the base 40 abuts on the lower regulating wall 306 in the groove 3 a of the mating member 3. In the surface opposite to the upper side portion 303 of the side portion 50, inclined surfaces 51s and 52s which are separated from the upper side portion 303 at the both end portions in the longitudinal direction D1 as shown in FIGS. Is formed. Here, it is assumed that the inclined surface 51s is formed on the first divided side 51, and the inclined surface 52s is formed on the second divided side 52. Further, in the surface opposite to the lower side 304 of the side 60, the both ends in the longitudinal direction D1 are inclined away from the lower side 304 so as to be longitudinally outward as shown in FIGS. 6 (a) and 6 (b). The surfaces 61s and 62s are formed. Here, the inclined surface 61s is formed on the first divided side 61, and the inclined surface 62s is formed on the second divided side 62. The inclined surfaces 51s, 52s, 61s, and 62s on the side portions 50 and 60 facilitate the insertion of the light guide rod 2 on which the externally fitted member 4 is externally fitted from the insertion opening 3f in the longitudinal direction D1, and externally fitted. It is easy to move the light guide rod 2 with the member 4 fitted outside in the groove 3a.

  On the side portion 50, an elastically deformable side spring portion 4f (an example of the spring portion 4a) which is bridged between the first divided side portion 51 and the second divided side portion 52 is formed. As shown in FIG. 6A, the side surface spring portion 4f is a first extension portion extending from the first divided side portion 51 in the direction D3 inclined from the longitudinal direction D1 toward the upper portion 303 of the groove 3a. 4b, having a second extension 4c extending from the longitudinal direction D1 to a direction D4 inclined to the opposite side to the upper side 303 of the groove 3a from the tip end 4b1 of the first extension 4b; There is. The tip of the second extension 4 c is connected to the second divided side 52. The angle between the inclined direction D3 and the longitudinal direction D1 may be, for example, about 5 to 20 degrees. The angle between the inclined direction D4 and the longitudinal direction D1 can be, for example, about 5 to 20 degrees. The front end 4b1 of the first extension 4b of the side spring 4f of the outer fitting member 4 externally fitted to the light guide rod 2 contacts the side 3d of the groove 3a, as shown in FIG. The biasing force F3 (example of the biasing force F1) in the direction in which the portion 4f pushes the side portion 3d is applied. Therefore, the generation of abnormal noise at the time of vibration input is suppressed. Further, since the first extending portion 4b and the second extending portion 4c extend in the longitudinal direction D1 as a whole, the light guide rod 2 with the outer fitting member 4 externally fitted is moved from the insertion opening 3f to the longitudinal direction D1. It is easy to insert, and it is easy to move the light guide rod 2 on which the outer fitting member 4 is externally fitted in the groove 3a.

  As shown in FIG. 5B and the like, in the first divided side portion 51, a through hole 51a is formed 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, an engagement hole 53 into which the convex portion 23a of the light guide rod 2 is inserted is formed as a through hole between the side surface spring portion 4f and the edge portion 50e. .

  As shown in FIG. 5A and the like, the side portion 60 is formed with a bridge portion 66 which is bridged between the first divided side portion 61 and the second divided side portion 62. In the first divided side portion 61, a through hole 61a is formed 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 the holes 61a and 62a and between the bridge portion 66 and the edge 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. The convex portion 23a longer in the longitudinal direction D1 than the convex portion 24a in the light guide bar 2 does not enter the engagement hole 63, so the externally fitting members 4 attached to the light guide bar 2 can be oriented in the same direction. In 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 second divided side portion 62 in the vicinity of the engagement hole 63. These protrusions 64, 65 are designed to contact the lower side 304 of the groove 3a together with the edge 60e.

(4) Method of forming light guide rod holding structure, function and effect:
The light guide bar holding structure 1 described above can be formed, for example, as follows.
First, the outer fitting member 4 is externally fitted to the light guide bar 2 in accordance with the positions of the convex portions 23 a and 24 a of the light guide bar 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 externally 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. Thus, as shown in FIG. 2, the plurality of outer fitting members 4 are externally fitted to the light guide rod 2 at intervals in the longitudinal direction D1. Each of the outer fitting members 4 is engaged with the convex portions 23a and 24a of the light guide bar 2 at the engagement holes 53 and 63, so that it does not come off the light guide bar 2 and the longitudinal direction with respect to the light guide bar 2 Do not move to D1. The light guide rods 2 in which the respective outer fitting members 4 are externally fitted as described above are respectively prepared for the pair of rail members 300 and the frame members 320.

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

  The pair of rail members 300 and the frame member 320 in which the light guide rod 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 lit, the light guide rod 2 housed in the groove 3a of the mating member 3 Light LT1 from the groove 3a, as shown in FIG. 9, illuminates the surface of the sunshade 5 in the closed state on the side of the passenger compartment 101. As shown in FIG. Here, since the pair of rail members 300 are disposed on the left and right of the opening 112 and the frame member 320 is disposed in front of the opening 112, the left edge of the opening 112 in the sunshade 5 seen from the opening 112 The section, the right edge and the strip along the front edge are illuminated. As described above, since the sunshade 5 of the cabin ceiling portion 102 is illuminated in a band along the edge of the opening 112, a good design is produced on the ceiling portion 102.

  In the light guide rod holding structure 1, the light guide rod 2 to which the outer fitting member 4 is externally fitted can be inserted in the insertion port 3f of the mating member 3 in the longitudinal direction D1, and the outer fitting member 4 is externally fitted to the groove 3a. It is regulated that the light guiding rod 2 accommodated in the housing 3 is separated from the groove 3a in the dropping direction D2 by the regulating structure 3g of the mating member 3. Therefore, 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 for covering the light guide rod 2 with the outer fitting member 4 externally fitted is also unnecessary. Therefore, the present light guide rod holding structure 1 requires a small number of members for holding the light guide rod, which leads to a reduction in the cost of parts. Further, as shown in Japanese Patent Application Laid-Open No. 2008-132807, there is no need to surround the periphery of the light guide with a long housing extending the entire length of the mounting groove, which leads to cost reduction of the material.

  Furthermore, even if the light guide rod holding structure 1 is incorporated into the metal counterpart member 3 in which abnormal noise is easily generated, the spring portion 4 a of the outer fitting member 4 externally fitted to the light guide rod 2 is a groove of the counterpart member 3 Since the biasing force F1 in the pushing direction is applied to the inner surface 3b of 3a, the generation of abnormal noise at the time of vibration input is suppressed. In particular, since the direction of the biasing force F2 by the bottom surface spring portion 4e is different from the direction of the biasing force F3 by the side surface spring portion 4f, the generation of abnormal noise at the time of vibration input is preferably suppressed.
