  However, the illuminating lamp having such a configuration is generally assembled in a state in which the functional portion cannot be removed from the design portion.

  The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a mounting structure of a lamp device that can easily replace a lamp.

In order to achieve the above-described object, the lamp device mounting structure according to the present invention is characterized by the following (1) to (2).
(1) A design part having a frame-shaped bezel and a window for emitting light from the lamp to the outside provided in the bezel; a functional part that has the lamp and can be assembled to the design part; A lamp device mounting structure for mounting a lamp device comprising a substantially rectangular opening in an interior material,

thing.

According to the mounting structure of the lamp device having the above configuration (1), the functional portion side is allowed to escape from the design portion side by sliding the bezel in the surface direction of the interior portion (for example, the direction substantially parallel to the ceiling surface). It has a locking means that can. Therefore, since the lamp device to which the design part is attached can be removed from the interior part and the functional part can be removed from the design part, the lamp can be easily replaced. In addition, the vehicle lamp can be detachably assembled to the interior portion with a simple structure using a minimum number of parts.
According to the mounting structure of the lamp device having the configuration (2), the engagement protrusion can be fitted into the engagement hole through the guide groove cut out parallel to the surface direction of the bezel. On the other hand, the functional unit can be attached and detached simply by sliding in the horizontal direction (for example, parallel to the ceiling surface), and the functional unit can be attached and detached when replacing the lamp. In addition, since the functional unit performs a locking operation in the vertical direction perpendicular to the surface of the interior portion (for example, the ceiling surface) with respect to the design portion, the vertical swinging is performed, for example, as in a lamp device for a vehicle. If the mounting structure of the present invention is applied to a vehicle that is highly likely to occur, it can be effectively prevented from swinging in the vertical direction, so that the occurrence of abnormal noise at the lock portion can also be suppressed.

  According to the mounting structure of the lamp device of the present invention, the lamp device can be removed from the interior portion, and the functional portion can be removed from the design portion, so that the bulb can be easily replaced.

  The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading through the best mode for carrying out the invention described below with reference to the accompanying drawings.

DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the accompanying drawings.
1 and 2 show a vanity lamp 10 (which constitutes the lamp device of the present invention) in which the mounting structure of the lamp device according to one embodiment of the present invention is applied to a ceiling-side interior material R (which constitutes the interior portion). It is shown. The vanity lamp 10 includes a design part 20 and a functional part 30 as a schematic configuration, and is detachable from a roof trim T attached to the inner peripheral edge of the opening R1 of the interior material R on the ceiling side. It has a simple structure.

  Among these, the design part 20 is against the roof trim T (see FIG. 4) attached to the opening R1 of the interior part (interior material R) on the ceiling side in the present embodiment among the interior parts (interior material R) of the vehicle. And a detachable frame-shaped bezel 21 and a lens portion 22 constituting a transparent (or translucent) exit window attached to the bezel 21. In addition, if this lens part 22 is made into the shape slightly depressed in the ceiling back part direction etc. with respect to the roof trim T, the vanity lamp 10 will be attached or detached to the roof trim T with the latching function in the latching part 211 mentioned later. It can also function as a latching means (or gripping means) that is latched (or gripped) by hand when operated.

  The bezel 21 has a clip 23 to be engaged with a protrusion T2 (details will be described later) of the roof trim T of the opening at one end 21A and a bracket 24 near the other end 21B.

  Further, as shown in FIG. 4A, the bezel 21 has a hooking portion 211 that branches into upper and lower multilayers (for example, branched into two layers in this embodiment) at the outer peripheral edge. When the vanity lamp 10 is attached to or detached from the roof trim T, for example, the bezel 21 is firmly grasped by hooking a finger to be operated on the hook portion 211, and the vanity lamp 10 is securely and easily attached and detached. it can. That is, since the latching portion 211 is formed of a thin shape, it can be easily latched by inserting a fingertip or a nail into the gap between the two layers. In particular, since the latching portion 211 has a bifurcated shape, it has a beautiful appearance, and it is difficult to imagine the function as the latching means from the outside. Therefore, design properties are enhanced at the same time as the gripping function. In addition, since it is formed into a thin wall by having two layers on the upper and lower sides, this hooking is performed when the vanity lamp 10 is attached and detached by providing flexibility and springiness that do not impair the hooking function. It is also possible to increase the degree of freedom of operation when attaching and detaching by making the stop portion 211 elastically deformable in the vertical direction.

  As shown in FIGS. 1 and 2 (and FIG. 7), the clip 23 is a thin plate-like upright portion 231 that stands upright on the front side (left side in FIGS. 1 and 2) of the bezel 21 (or the lens portion 22). And a thin plate-like neck portion 232 having a substantially inverted U-shape that continues from the upright portion 231 and a head portion 233 that hangs downward from the neck portion 232 toward the front. In particular, the upright portion 231 and the neck portion 232 are configured to have a spring property that can swing in the front-rear direction because the shape thereof is a thin plate shape, and the head 233 that is inclined downward is displaced in the front-rear direction. It becomes possible.

  Further, as shown in FIG. 7, the head portion 233 is provided with a wedge-shaped inclined surface 233A having a tip surface inclined toward the front lower side, and adjacent to the inclined surface 233A (the above-mentioned roof trim T is described above). And a hook-like locking surface 233B that is locked to the protruding portion T2.

  In particular, the inclined surface 233A has a unique shape and a unique inclination angle that are mechanically considered. That is, on the inclined surface 233A having this unique shape and inclination angle, the vanity lamp (lamp device) 10 is pushed in from the outside (downward in FIG. 7) against the protrusion T2 provided on the outer edge of the roof trim T described later. Then, after the head 233 is retracted backward and passes through the protrusion T2, the locking surface 233B returns to the front by a spring force, so that it can be easily engaged with the protrusion T2. On the other hand, when the vanity lamp 10 is pulled out to the outside (downward in FIG. 7), the head 233 can be retracted once and can escape through the projection T2, so that the locking surface 233B is pulled out from the projection T2. Can be easily disengaged.

  The bracket 24 is composed of a pair of thin wall surfaces upright in the thickness direction perpendicular to the surface direction of the bezel 21 (α direction in FIG. 2), and a pair is attached to both sides of the bezel 21 on the other end 21B side. It is formed upright. The bracket 24 includes a lock unit 40 that allows the functional unit 30 side to escape from the bezel 21 side by a sliding operation toward the surface direction of the design unit 20 with respect to the functional unit 30 mounted on the bezel 21 side.

  The locking means 40 engages with a pair of engaging protrusions 41 provided on both side surfaces of the main body 31 of the functional unit 30 to be described later, and has an engagement hole having a substantially circular notch portion through which the engaging protrusions 41 can enter and exit. 42 is provided.

  Among these, as shown in FIG. 3, the engagement protrusion 41 includes a circular protrusion 411 having a perfect circle shape with an outer diameter D1, and a narrow width D2 connected to the rear of the circular protrusion 411 (where D1> D2). However, the square protrusion 412 is not essential.

  On the other hand, as shown in FIG. 3, the engagement hole 42 has an inner diameter D3 that is substantially the same as or slightly larger than the outer diameter D1 of the circular protrusion 411 (ie, D3 ≧ D1), and the circular protrusion 411 is fitted therein. The groove 421 has a width D4 (ie, D3 ≧ D1> D4> D2) that is at least smaller than the outer diameter D1 of the circular protrusion 411 in order to guide the circular protrusion 411 from the outside to the lock groove 421. A guide hole portion 422 formed between the lock groove portion 421 and the outer edge portion is provided.

  If the guide hole 422 has a shape that expands toward the outside as shown by a broken line in FIG. 3, the introduction and withdrawal of the engagement protrusion 41 to and from the guide hole 422 is easier and smoother. This is preferable because it can be performed. In addition, after the circular protrusion 411 is fitted into the lock groove part 421, the guide hole part 422 is oscillated by the circular protrusion 411 (and the functional part 30 provided with the same) with the lock groove part 421 as a rotation center. In order to enable dynamic displacement, it is preferable that the notch is cut out to some extent as compared with the rectangular protrusion 412. In this way, the function unit 30 can be swung in order to secure a degree of freedom when the vanity lamp 10 is attached to and detached from the roof trim T, and a detailed description thereof will be described later.

  In order to allow the circular protrusion 411 of the engagement protrusion 41 to pass through the lock groove 421 and fit into the circular protrusion 411, at least a portion provided with the engagement hole 42 in the bracket 32, or the engagement protrusion About the part which forms 41 circular protrusion 411, it is preferable to form with the material which has elasticity or flexibility in material.

  On the other hand, the functional unit 30 includes a main body 31 of the functional unit 30, a socket 32 for attaching a lamp L (or bulb) as a light source provided on the front end portion 31 </ b> A side of the main body 31, and both side surfaces of the main body 31. The above-described engaging protrusion 41 provided and a protruding portion 34 having a cord clip 33 provided to protrude toward the rear end portion 31B side of the main body 31 (accommodating an electric wire WH described later) are provided. Further, the socket 32 is connected to an electric wire WH having a cap portion or the like disposed on the back side of the ceiling, and feeds power to the lamp L from a battery not shown.

  The socket 32 is provided with a base made of a conductive metal (not shown) to which the lamp L is mounted by a mechanism for screwing the socket 32. The one end of the harness WH) is electrically connected by solder or other appropriate means. In addition, since the electric wire connected with this socket 32 side is carried together with this when the vanity lamp 10 is taken out from the back side of the ceiling, the vanity lamp 10 can be removed and moved freely within a certain range. In order to allow this, an extra length not shown is provided on the ceiling or the like.

  As shown in FIGS. 4B and 7, the roof trim T is branched into two upper and lower layers in the thickness direction so as to fit into the inner peripheral edge of the opening R1 of the interior material R in the ceiling portion. In addition to the outer peripheral edge T1 forming T0, the vicinity of the outer peripheral edge T1 has protrusions T2 and T3 protruding toward the back of the ceiling (depressed when viewed from the outside). ing. By providing the projecting portions T2 and T3 projecting toward the inner part of the interior material R of the ceiling portion, the clip 23 of the design unit 20 and the function unit 30 projecting unit 34 described later are formed between the bezel 21 and each. The design portion 20 can be assembled to the roof trim T because the gap can be used to sandwich and lock the roof trim T.

  In particular, in the present invention, the design unit 20 is moved relative to the functional unit 30 by the locking means 40 in the plane direction (−α direction in FIG. 2) not perpendicular to the thickness direction of the bezel 21. Since the design part 20 can be released from the engagement lock state with the function part 30, the design part 20 can be escaped from the roof trim T. That is, the design part 20 is engaged with the roof trim T in a detachable state. As will be described later, the engagement force between the functional portion 30 and the design portion 20 by the locking means 40 is weaker than the engagement force between the protruding portion 34 of the functional portion 30 and the protrusion T3 of the roof trim T. If it is comprised, the functional part 30 can also be comprised so that it can escape from the roof trim T side in the state integrated with the design part 20 simultaneously.

  Next, an operation for attaching the vanity lamp 10 as the lamp device according to the present embodiment to the roof trim T provided on the ceiling portion and an operation for making it escape will be described in detail with reference to FIGS. To do.

  First, as for the vanity lamp 10, as shown in FIG. 9A, the functional portion 30 is directed toward the engaging hole 42 that constitutes a part of the locking means 40 provided in the bracket 24 of the design portion 20. Engagement protrusions 41 constituting a part of the lock means 40 provided on the main body 31 are fitted. As a result, as shown in FIG. 5B, the functional unit 30 is locked and integrated with the design unit 20. Note that the functional unit 30 is configured so that the electrical connection between the electric wire WH previously wired on the back side of the ceiling and the socket is the first assembly of the vanity lamp 10 to the roof trim T, that is, the initial assembly. It is necessary to go ahead of time.

  In this way, as shown in FIG. 5, the vanity lamp 10 after assembling the functional unit 30 is arranged immediately below the opening portion of the roof trim T provided on the ceiling portion.

  Next, as shown in FIG. 6, the opening portion of the roof trim T is first set while maintaining the inclined state in which the rear of the vanity lamp 10 faces upward so that the functional unit 30 approaches the ceiling portion. The vanity lamp 10 is inserted in the direction toward the back of the ceiling so that the functional unit 30 on the rear side can pass through.

  Thereafter, the clip 23 on the front side of the design portion 20 is gradually raised upward so as to pass through the opening portion of the roof trim T, and the bezel 21 of the vanity lamp 10 is roof trimmed as shown in FIG. Assemble to the opening of T.

  In this way, the bezel 21 of the vanity lamp 10 is assembled to the roof trim T. That is, the protrusion T <b> 2 of the roof trim T is sandwiched and locked by the gap between the clip 23 on the front side of the design portion 20 and the bezel 21. At the same time, the protrusion T3 on the side opposite to the protrusion T2 of the roof trim T is sandwiched and locked in the gap between the protrusion 34 of the functional part 30 and the bezel 21. As a result, the front and rear sides of the vanity lamp 10 are assembled to the roof trim T.

  Here, in order to stabilize the assembled state, for example, by attaching a double-sided tape to the rear side rear surface (upper surface) of the bezel 21 and performing a secondary fixing process, the assembled state with respect to the roof trim T Is further stabilized, and it is possible to prevent the vanity lamp 10 from being accidentally dropped from the roof trim T.

  Next, the vanity lamp 10 can be removed from the roof trim T by performing a required detachment operation from the assembled state. In addition, when the secondary fixing process is performed with the tape described above, an operation of peeling the double-sided tape from the roof trim T with an appropriate jig or the like is performed simultaneously.

  That is, the operation of pulling out the front side of the vanity lamp 10 in the direction of the floor on the near side away from the ceiling side and the operation of sliding the vanity lamp 10 in the separating direction γ as shown in FIG. Do. Then, the displacement of the clip 23 shown in FIG. 7 in the direction in which the clip 23 is detached from the protrusion T2 of the roof trim T, that is, immediately after the head 233 slightly pivots and displaces clockwise in the clockwise direction and gets over the protrusion T2. A restoring operation that elastically returns counterclockwise is performed. Thereby, the engagement state with the protrusion T2 is released. Therefore, the vanity lamp 10 can be escaped from the roof trim T by subsequently performing a sliding operation directed diagonally forward and downward.

When this vanity lamp (which constitutes the lamp device of the present invention) 10 is operated to escape from the roof trim T, the following two modes can be considered. That is,
(1) An aspect (hereinafter referred to as a first aspect) in which the design part 20 and the functional part 30 constituting the vanity lamp 10 are integrated, and both the design part 20 and the functional part 30 are operated to escape from the roof trim T.
(2) Of the design part 20 and the functional part 30 constituting the vanity lamp 10, the vanity lamp 10 provided with the design part 20 is left in the roof trim while only the functional part 30 is engaged with the roof trim T. A mode of performing an escape operation from T (hereinafter referred to as a second mode);
Can be considered.

  Among these, the first mode is suitable for inspection and repair of the functional unit 30 in addition to the replacement operation of the lamp L since the entire functional unit 30 is taken out, while the second mode is exclusively used for the replacement operation of the lamp L. Is suitable. Which of these modes is performed depends on the first output F1 required for the engagement protrusion 41 of the lock means 40 to escape from the engagement hole 42, and the protrusion 34 of the functional portion 30 is the protrusion of the roof trim T. Depends on the magnitude relationship with the second output F2 required to escape from the state locked at T3.

  Therefore, it is convenient to match the frequency of the replacement operation of the lamp L and the frequency of the inspection / repair operation of the functional unit 30, whichever is higher, but in general, the replacement frequency of the lamp L is higher. The second mode may be configured to be executed. For this purpose, the first output F1 may be configured to be set smaller than the second output F2. Specifically, for example, the groove width D4 of the guide hole 422 with respect to the outer diameter D1 of the circular protrusion 411 shown in FIG. 3 may be formed as large as possible, or the bracket 24 on the design part 20 side. Alternatively, the material of the circular protrusion 411 on the function unit 30 side may be formed of a material that is more elastically deformed.

  On the other hand, if importance is attached to the ease of inspection and repair work of the functional unit 30 even if the frequency is low, the first output F1 may be configured to be set larger than the second output F2.

  The present invention is not limited to the embodiment described above, and can be implemented in various forms without departing from the gist of the present invention.
