The functional unit 22 includes a pair of bezels 6, a pair of switch knobs 7, and an inner housing 23 to which a functional component (not shown) (which is the same as a conventional one) is assembled.

  The vehicle interior illumination lamp 21 of the present invention is characterized by a pair of locks 24 and a pair of locks 25 formed in the inner housing 23 that constitutes the functional unit 22. The other portions are formed in the same manner as in the prior art, and the description here is omitted (the portions whose description is omitted are disclosed in detail in Patent Document 1).

  1 to 3, the pair of locks 24 formed on the side portion 9 of the resin inner housing 23 are arranged and formed at the same interval as the lock 12 of the conventional example (see FIG. 11). Also, as shown in FIG. 3, the pair of locks 25 formed on the side portion 10 of the inner housing 23 is also arranged and formed at the same interval as the lock 13 of the conventional example (see FIG. 11). The pair of locks 24 and the pair of locks 25 are fitted into openings 15 (flat portions 17) formed in the roof panel 14 as in the prior art, that is, as shown in FIG. It is formed so that it can be fixed to the panel 14. Hereinafter, characteristic portions will be described with reference to FIGS. 1 to 4 (mainly referring to FIG. 4).

  The pair of locks 24 are connected by a connecting portion 26 extending in the direction of the interval, and move together when bent. Further, the pair of locks 25 are also connected by a connecting portion 27 extending in the direction of the interval, and move integrally when bent. The pair of locks 24 connected by the connecting portion 26 are in a state in which twisting is unlikely to occur. In addition, the pair of locks 25 connected by the connecting portion 27 is also in a state in which twisting is unlikely to occur.

  The shape of the lock 24 is as follows. In FIG. 4, a flexible first arm portion 29 constituting the lock 24 is formed in the cutout portion 28 of the side portion 9. The first arm portion 29 is coupled to the main body (reference numeral omitted) of the inner housing 23 via the proximal end portion 30. Here, the downward arrow P in FIG. 4 is defined as the indoor side, the upward arrow P is defined as the back side of the roof panel 14, and the arrow Q orthogonal to the arrow P is defined as the extending side of the roof panel 14. The arm portion 29 is formed along the direction of the arrow P. The base end portion 30 of the first arm portion 29 is formed to be slightly thicker than the other portions, and the bending portion is adjusted. The first arm portion 29 is formed so as to be bent toward the inner side of the inner housing 23. A flexible second arm portion 32 is coupled to the tip portion 31 of the first arm portion 29. The second arm portion 32 is formed so as to extend along the direction of the arrow Q and toward the outside of the inner housing 23.

  The distal end portion 31 and the second arm portion 32 of the first arm portion 29 are shaped so as to be relatively thin so that these portions are easily bent (the first arm portion 29 is more easily bent). Is formed. For this reason, although it can be said that the shape is likely to be twisted, in the present invention, the presence of the connecting portion 26 can prevent twisting.

  The distal end portion 33 of the second arm portion 32 is coupled with a lock main body portion 34 having a shape that gradually increases in thickness from this portion. The lock body 34 is formed in a shape having a substantially claw-shaped cross section as shown in the figure.

  In the outer shape of the cross-sectional shape of the lock main body 34, the reference numeral 35 indicates a portion that is inside the lock. Reference numeral 36 indicates a portion outside the lock. The lock inner side 35 is formed in an outer shape along the direction of the arrow P. Further, the lock inner side 35 is formed in an outer shape that is parallel to the first arm portion 29 at a predetermined interval. On the other hand, the lock outer side 36 is formed in an outer shape that gradually separates from the lock inner side 35. The lock outer side 36 is formed as a portion that abuts on and slides on the opening 15 of the roof panel 14. When the lock outer side 36 slides on the opening 15, the lock 24 is bent to the inside of the inner housing 23.

  A fitting surface 16 is formed on the lock body 34. The fitting surface 16 is formed as a flat surface along the arrow Q direction. The fitting surface 16 is formed as a portion that is hooked (fitted) to the flat portion 17 formed on the periphery of the opening 15. An operation unit 37 is formed on the inner side of the fitting surface 16. The operation portion 37 is formed so as to be continuous with the lock main body portion 34 and along the direction of the arrow P. The operation unit 37 is formed in a cantilever arm shape.

  Reference numeral 38 indicates a jig insertion slot for inserting a release jig (not shown). When the release jig is inserted into the jig insertion slot 38 and the operation portion 37 is pushed inward, the lock 24 is The second arm portion 32 and the distal end portion 33 are bent at the position, whereby the engagement between the fitting surface 16 and the flat portion 17 is released. Since the pair of locks 24 are connected by the connecting portion 26, the above-described catch can be released simply by pushing one operating portion 37 of the two locks 24 with a release jig. It is possible. In the present invention, it can be said that one release jig is sufficient.

  The connecting portion 26 is formed in a band plate shape (the shape is an example. The shape is not particularly limited as long as the pair of locks 24 can be moved integrally). The connecting portion 26 is arranged and formed in accordance with the position and outer shape of the lock outer side 36 (it may be arranged and formed on the lock inner side 35). A connecting side fitting portion 39 is formed in such a connecting portion 26.

  Of the pair of end portions parallel to the extending direction of the connecting portion 26, the connecting side fitting portion 39 corresponds to an end portion on the side close to the opening 15 of the roof panel 14. The connection side fitting portion 39 is arranged and formed so as to be continuous with the fitting surface 16 of the lock 24 or at a position near the fitting surface 16. The connection side fitting part 39 is formed as a part (part to be locked) to be fitted to the flat part 17. Since the connecting portion 26 is arranged and formed in accordance with the position and outer shape of the lock outer side 36 as described above, the surface indicated by the reference numeral 40 is a sliding surface with respect to the opening 15. The sliding surface 40 is formed as a flat and smooth surface, and can slide smoothly with respect to the opening 15.

  On the other hand, the shape of the lock 25 is as follows. In FIG. 4, a flexible first arm portion 42 constituting the lock 25 is formed in the lock forming portion 41 of the side portion 10. The first arm portion 42 is coupled to the main body via a base end portion 43. The first arm portion 42 is formed in an oblique arm shape so as to be inclined outward with respect to the direction of the arrow P. The base end portion 43 of the first arm portion 42 is formed to be slightly thicker than the other portions, and the bent portion is adjusted. The first arm portion 42 is formed so as to be bent toward the inner side of the inner housing 23. A short second arm portion 45 is coupled to the tip portion 44 of the first arm portion 42. The second arm portion 45 is formed so as to extend short along the direction of the arrow Q and toward the outside of the inner housing 23.

  The distal end portion 44 of the first arm portion 42 and the second arm portion 45 are formed in a shape that becomes relatively thin like the lock 24. For this reason, it can be said that the lock 25 is easily twisted. However, in the present invention, the presence of the connecting portion 27 can prevent twisting.

  A lock main body portion 46 is coupled to the second arm portion 45. The second arm portion 45 is disposed and formed as a portion that shortly connects the first arm portion 42 and the lock main body portion 46. The lock main body portion 46 is formed in a shape that gradually increases in thickness from the coupled portion of the second arm portion 45. The lock main body 46 is formed in a shape having a substantially claw-shaped cross section as shown in the figure.

  In the outer shape of the cross-sectional shape of the lock main body 46, the reference numeral 47 indicates a portion on the lock inner side. Reference numeral 48 indicates a portion outside the lock. The lock inner side 47 is formed in an outer shape along the direction of the arrow P. Since the lock inner side 47 has an outer shape along the direction of the arrow P, it is formed in an outer shape that is not parallel to the first arm portion 42. On the other hand, the lock outer side 48 is formed in an outer shape that gradually separates from the lock inner side 47. The lock outer side 48 is formed as a part that abuts on and slides on the opening 15 of the roof panel 14. When the lock outer side 48 slides on the opening 15, the lock 25 is bent toward the inner side of the inner housing 23.

  A fitting surface 16 is formed on the lock main body 46. The fitting surface 16 is formed as a flat surface along the arrow Q direction. The fitting surface 16 is formed as a portion that is hooked (fitted) to the flat portion 17 formed on the periphery of the opening 15. An operation portion 49 is formed inside the fitting surface 16. The operation portion 49 is formed so as to be continuous with the lock main body portion 46 and along the direction of the arrow P. The operation unit 49 is formed in a cantilevered arm shape. The operation unit 49 has the same function as the operation unit 37 of the lock 24. When a release jig is inserted into the jig insertion port 38 and the operation unit 49 is pushed inward, the lock 25 mainly includes the first arm unit. At 42, the engagement between the fitting surface 16 and the flat portion 17 is released. Since the pair of locks 25 are connected by the connecting portion 27, the above-mentioned catch can be released simply by pushing one operating portion 49 of the two locks 25 with a release jig. It is possible.

  The connecting portion 27 is formed in a band plate shape (the shape is an example. The shape is not particularly limited as long as the pair of locks 25 can be moved integrally). The connecting portion 27 is arranged and formed according to the position and outer shape of the lock outer side 48 (it may be arranged and formed on the lock inner side 47). In such a connecting portion 27, a connecting side fitting portion 50 is formed.

  Of the pair of end portions parallel to the direction in which the connecting portion 27 extends, the connecting-side fitting portion 50 corresponds to an end portion on the side close to the opening 15 of the roof panel 14. The connection side fitting part 50 is arranged and formed so as to be continuous with the fitting surface 16 of the lock 25 or at a position near the fitting surface 16. The connection side fitting portion 50 is formed as a portion (a portion to be locked) that is fitted to the flat portion 17 like the connection side fitting portion 39 of the lock 24. Since the connecting portion 27 is arranged and formed in accordance with the position and outer shape of the lock outer side 48 as described above, the surface indicated by the reference numeral 51 is a sliding surface with respect to the opening portion 15. The sliding surface 51 is formed as a flat and smooth surface, and can slide smoothly with respect to the opening 15.

  As described above with reference to FIGS. 1 to 4, according to the present invention, the locks 24 connected by the connecting portion 26 and the locks 25 connected by the connecting portion 27 move integrally. In addition, since the connecting portions 26 and 27 are connected, the locks 24 and 25 themselves are much less likely to be twisted than in the conventional example. Therefore, when the vehicle interior illumination lamp 21 is inserted into the opening 15 of the roof panel 14 (attachment target member), the insertion force can be prevented from becoming larger than necessary. In addition, since the locks 24 and 25 move together, the half-fitting can be prevented during the insertion, and the number of times the release jig is used during the removal can be reduced. There is an effect that can be done. Furthermore, according to this invention, there exists an effect that it can contribute to the workability | operativity improvement at the time of the said insertion, and the effect that it can be set as the vehicle interior lighting 21 which is hard to drop out.

  It goes without saying that the present invention can be variously modified without departing from the spirit of the present invention. In the above description, two locks 24 and 25 are formed. However, the present invention is not limited to this, and three or more locks may be arranged and formed. That is, the connecting portion may be formed so as to straddle three or more locks.

  Here, a modified example of the connecting portion 26 will be described with reference to FIGS. 5 to 8 (the modified example is applicable to the connecting portion 27). The description will be made on the assumption that the engagement between the vehicle interior illumination lamp 21 and the roof panel 14 is set large, and the vehicle interior illumination lamp 21 is tilted by an angle θ within the range of the engagement clearance. Shall.

  In FIG. 5, if the vehicle interior illumination lamp 21 is tilted by an angle θ and fitted to the roof panel 14, there is a possibility that the catch at the position of the arrow A does not occur. Specifically, the connecting portion 26 interferes with the opening 15 (see FIG. 4) at the position of the arrow A, so that the fitting surface 16 (see FIG. 4) is not caught on the flat portion 17 (see FIG. 4). there is a possibility. As a countermeasure, it is conceivable to change the connecting portion 26 to a connecting portion 26 'as shown in FIG.

  In FIG. 6, the connecting portion 26 ′ has an end 61 that extends in the direction of the interval between the pair of locks 24 in an arc shape. The end portion 61 is formed so that the intermediate 63 protrudes from both sides 62 (both sides of the end portion at the position of the arrow B). The end portion 61 may be formed in a trapezoidal shape, a mountain shape (wave shape) in which one or a plurality of mountains exist, in addition to the arc shape described above. By connecting the pair of locks 24 with such a connecting portion 26 ', the vehicle interior illumination lamp 21' is properly fitted as shown in FIG. Further, when the vehicle interior illumination lamp 21 ′ is tilted by an angle θ, the state shown in FIG. 8 is obtained. 7 and 8, the intermediate 63 is caught on the flat portion 17 (see FIG. 4).

  As can be seen from FIG. 8, the connecting portion 26 ′ has a shape in which both sides 62 of the end portion 61 are scraped off compared to the intermediate 63, so that the connecting portion 26 ′ is opened at the position of the arrow A. (Refer to FIG. 4), and the vehicle interior illumination lamp 21 is securely fitted even if it is inclined by the angle θ.
