  In the following description, it is assumed that the directions of front, rear, up, down, left, and right are indicated in a state in which the vehicle room light 1 is attached to the ceiling 100. Note that the directions of front, rear, upper, lower, left, and right shown below are for convenience of explanation, and the present invention is not limited to these directions.

  The vehicle interior light 1 has a housing 2, a lighting body 3 and a cover 4 (see FIGS. 2 and 3).

  The housing 2 is formed in a flat shape, and has a light receiving portion 2a opened downward at a portion excluding the outer peripheral portion. The housing 2 has a horizontally elongated frame-shaped portion 5 formed in a substantially rectangular shape and a substantially plate-shaped closing plate portion 6 attached to the frame-shaped portion 5 from above (see FIGS. 2 to 4).

  The frame portion 5 has a front portion 7 extending in the left and right direction, a rear portion 8 extending in the left and right direction, and side portions 9 and 9 extending in the front and rear direction. The left and right ends of the rear portion 8 are continuous with the rear ends of the side portions 9, respectively.

  From the front part 7, the pressing pieces 10, 10 projecting backward are protruded, and one pressing piece 10 is provided with a guide pin 10 a projecting upward. The pressing pieces 10, 10 are spaced apart to the left and right. A positioning spring 11 is projected rearward from a portion near one end in the left-right direction of the front portion 7. The tip end of the positioning spring 11 is bent upward with respect to the other portion, and is provided as a sliding engagement portion 11a. The positioning spring 11 is elastically deformable with a continuous portion with the front portion 7 as a fulcrum in a direction in which the sliding engagement portion 11a is displaced substantially in the left and right direction.

  At a central portion in the left-right direction of the front portion 7, a disposition recess 7a opened downward is formed. A release button 12 provided with a locking projection (not shown) is disposed in the placement recess 7a.

  The lower surface of the rear portion 8 is formed as a pressed portion 8a.

The changeover switch 24 is positioned, for example, near the rear end of one end in the left-right direction of the substrate 21. The changeover switch 24 has a function of switching between the lighted state and the extinguished state of the illumination body 3. When the changeover switch 24 is operated, the light emitting elements 23, 23,... Are lighted and light is emitted. The light emitted from the light emitting elements 23, 23,... Is transmitted through the light transmitting plate 22b of the light transmitting cover 22, diffused, and emitted toward the outside. The changeover switch 24 is operated by the switching operation unit 18 b of the second lever 189.

  The cover 4 is formed in a flat, horizontally long, substantially rectangular shape, and is rotatable relative to the housing 2 (see FIGS. 1 to 3). By turning the cover 4, the lighting body 3 is opened and closed, and the cover 4 is turned in the closing direction which is the opposite direction of the opening direction for opening the lighting body 3 and the opening direction. The cover 4 is pivoted relative to the housing 2 between a closed position (see FIG. 2) which closes the lighting body 3 and an open position which opens the lighting body 3, and the first open position (FIG. 3) See) and a second open position. The second open position is a position where the rotation angle is larger than the rotation angle of the first open position.

  The cover 4 is provided as a pivot 25 that extends in the lateral direction at one end in the lateral direction (see FIGS. 3 and 4). A concave portion 26 is formed at a position near one end in the left-right direction of the rotation fulcrum portion 25, and a bottom surface forming the concave portion 26 is formed as a movement operation portion 26 a.

  A mirror 27 is attached to the cover 4 on the inner side. A lock hole (not shown) is formed at the end of the cover 4 opposite to the pivot 25.

  The cover 4 is entirely accommodated in the illumination accommodating portion 2a of the housing 2 in the closed position (see FIG. 2). By the whole cover 4 being accommodated in the illumination accommodation part 2a in the closed position, thinning of the interior lamp 1 for a vehicle can be achieved.

  The housing 2 and the cover 4 are connected by connection arms 28 (see FIG. 4). One connecting arm 28 and the other connecting arm 28 are formed in symmetrical shapes.

  As shown in FIG. 10, the connection arms 28 and 28 have main shaft portions 29 and 29 extending in the front and rear direction, and substantially L-shaped continuous portions 30 and 30 connected to the rear end portions of the main shaft portions 29 and 29, Fulcrum shaft portions 31, 31 protruding outward in the left-right direction from the front end portions of the main shaft portions 29, 29, and a supported shaft portion 32 protruding inward in the left-right direction from the front end portions of the main shaft portions 29, 29; 32 and portions to be held 33 33 that project outward in the left-right direction from the rear ends of the main shaft portions 29 29, and inwards in the left-right direction from the rear ends of the connecting portions 30, 30 It has connecting shaft parts 34, 34.

  The connection arms 28, 28 are pivotably connected to the front end portions of the support shafts 31, 31 at the side portions 9, 9 of the housing 2, respectively, and the connection shaft portions 34, 34 are rotation support points of the cover 4 respectively. It is rotatably connected to the portion 25 (see FIGS. 4 and 5). Thus, the housing 2 and the cover 4 are connected by the connecting arms 28, 28.

  The supported shaft portions 32 and 32 are rotatably supported by the support protrusions 22 c and 22 c of the light transmitting cover 22. Accordingly, the connecting arms 28 are pivotable relative to the light transmitting cover 22 about the supported shaft portions 32.

  When the cover 4 is pivoted between the closed position and the first open position with respect to the housing 2, the held portions 33, 33 of the connecting arms 28, 28 are the holding portions 9 a of the side portions 9, 9. It is inserted into and held by 9a, and the detachment of the held portions 33, 33 from the holding portions 9a, 9a is regulated by the holding projections 9b, 9c (see FIG. 5).

  In the state where the held portions 33, 33 are held by the holding portions 9a, 9a, the connecting arms 28, 28 are positioned at the first position where the main spindles 29, 29 are in a horizontal state (see FIG. 11) . The connection arms 28, 28 are movable from the first position to the second position by releasing the holding of the held portions 33, 33 by the holding portions 9a, 9a.

<Mounting of interior lights for vehicles>
The vehicle interior lamp 1 configured as described above is attached to the ceiling 100 by fitting a part of the housing 2 or the like into the attachment portion of the cabin, for example, the attachment recess 100a formed in the ceiling 100 of the cabin. (Refer FIG.12 and FIG.13). When the housing 2 or the like is fitted into the mounting recess 100 a, the mounting springs 16, 16 of the mounting slider 13 are engaged with the mounting brackets 101, 101 fixed to the ceiling 100. At this time, the mounting springs 16, 16 are elastically deformed, and the mounting portions 16a, 16a are engaged in a state of being pressed against the mounting brackets 101, 101.

  Further, as described above, the mounting slider 13 is movable in the left-right direction with respect to the housing 2. Therefore, even when manufacturing tolerances occur with respect to the position of the mounting bracket 101, 101 relative to the mounting recess 100a, the mounting spring 16, 16 can be properly engaged with the mounting bracket 101, 101 and the housing 2 can be The vehicle interior lamp 1 can be attached to the attachment portion such as the ceiling 100 in a state where the vehicle interior light 1 is positioned at the regular position with respect to the attachment recess 100 a.

  Furthermore, in a state in which no force in the left-right direction is applied to the mounting slider 13, the mounting slider 13 is positioned approximately at the center of the movement range in the left-right direction. Therefore, since the mounting slider 13 is always positioned approximately at the center of the movement range when mounting the vehicle interior light 1 to the ceiling 100 or the like, the vehicle interior light 1 can be easily mounted to the ceiling 100 or the like. Can.

  In the above example, the mounting spring 16 is provided on the mounting slider 13 and the mounting bracket 101 is provided on the mounting portion such as the ceiling 100. Conversely, the mounting bracket is provided on the mounting slider and mounted. The part may be provided with a mounting spring.

  Further, although the example in which the upper surface side portion of the vehicle interior lamp 1 is attached inside the ceiling 100 by the attachment spring 16 has been described above, any portion of the vehicle interior lamp 1 is the vehicle body such as the ceiling 100 It may be attached to a part.

<Operation of interior lights for vehicles>
The operation of each part when the cover 4 is rotated in the vehicle room light 1 will be described below.

  The cover 4 is held in the closed position by the locking projection provided on the release button 12 being engaged with the locked hole of the cover 4 in the closed position (see FIGS. 2 and 11). At this time, the cover 4 is biased in the opening direction by, for example, a spring member (not shown).

  When the release button 12 is operated, the engagement of the locking projection with the locked hole is released, and the cover 4 is pivoted in the opening direction with respect to the housing 2 by the biasing force of the spring member (FIG. 14). reference). The cover 4 is pivoted toward the first open position with the connecting shaft portions 34, 34 of the connecting arms 28, 28 as a fulcrum.

  Although the example in which the cover 4 is pivoted in the opening direction by the biasing force of the spring member has been described above, no spring member is provided in the vehicular interior lamp 1 and the cover 4 is manually turned in the opening direction. It may be moved. Further, the cover 4 may be pivoted in the opening direction by its own weight. Furthermore, a structure in which friction occurs between the cover 4 and the connection arms 28 may be provided, and the cover 4 may be configured to be held at an arbitrary rotational angle with respect to the housing 2 by the friction.

  Immediately after the rotation of the cover 4 is started, the movement operation portion 26a of the cover 4 is separated from the operated portion 17b of the first lever 17, and the first lever 17 is not rotated. A second lever 18 is located at the rear end of travel.

  When the cover 4 is rotated to a predetermined rotation angle, for example, 45 degrees, the movement operation portion 26a is brought into contact with the operated portion 17b (see FIG. 14).

  When the cover 4 is continuously rotated, the movement operation unit 26a is slid on the operated unit 17b, the operated unit 17b is operated, and the first lever 17 and the second lever 18 are rotated relative to each other. At the same time, the switching operation portion 18b of the second lever 18 is moved forward (see FIG. 15). When the switching operation unit 18b is moved forward, the switching switch 24 is operated by the switching operation unit 18b, light is emitted from the light emitting elements 23, 23, ..., and the diffused light is the illumination body 3 It is irradiated from the outside to the outside.

  The cover 4 is rotated in the opening direction until the outer surface is in contact with the pressed portion 8a of the rear portion 8 of the housing 2, and a portion of the outer surface of the cover 4 near the pivot point 25 contacts the pressed portion 8a. The rotation is restricted and held in the first open position (see FIGS. 15 and 16). Therefore, a portion of the outer surface of the cover 4 which is closer to the rotation fulcrum portion 25 functions as a pressing portion 4a which is pressed against the pressed portion 8a.

  In the state in which the cover 4 is held in the first open position, the rotation angle of the cover 4 is, for example, 135 degrees, and the switch 24 switches even in the state in which the cover 4 reaches the first open position. The light is emitted from the light emitting elements 23, 23,...

  The pivoting of the cover 4 from the closed position of the cover 4 to the first open position is performed with the connecting arms 28, 28 in the first position. Therefore, when the cover 4 is pivoted from the closed position to the first open position, the held portions 33, 33 are held by the holding portions 9a, 9a.

  In any state where the cover 4 described above is pivoted from the closed position to the first open position, the user can use the mirror 27 attached to the cover 4 and from the closed position to the first open position The state up to is the state in which the vehicle room lamp 1 is used by the user.

  In addition, the rotation operation from the first open position of the cover 4 to the closed position is performed by, for example, manually rotating the cover 4 in the closed direction in the opposite direction to the above. The cover 4 is held by the locking projections provided at 12 being engaged with the lock holes of the cover 4.

  On the other hand, when the vehicle interior light 1 is used, the user may erroneously apply a force in the opening direction to the cover 4 while the cover 4 is pivoted to the first open position. There is.

  Thus, when a force in the opening direction is applied to the cover 4 rotated to the first open position, the pressing portion 4a of the cover 4 is pressed against the pressed portion 8a of the housing 2 Because of this, a force is generated on the cover 4 in a direction in which the pivoting fulcrum portion 25 is moved substantially downward with the pressing portion 4a as a fulcrum. Therefore, the held portions 33, 33 of the connecting arms 28, 28 connected to the cover 4 are slid on the inclined surfaces 9c, 8c and pulled out from the holding portions 9a, 9a, and held by the holding portions 9a, 9a. The holding of 33, 33 is released (see FIG. 17).

  When the held portions 33, 33 are pulled out of the holding portions 9a, 9a, the main shaft portions 29, 29 of the connecting arms 28, 28 are elastically deformed. When the held portions 33, 33 are pulled out from the holding portions 9a, 9a, the connecting arms 28, 28 are pivoted with respect to the housing 2 with the supporting shafts 31, 31 as supporting points and the cover 4 is connected with the connecting shaft 34, It is pivoted in the opening direction with respect to the connecting arms 28, 28 with 34 as a supporting point.

  The connecting arms 28, 28 are moved substantially downward to move the connecting shafts 34, 34 to the second position, and the cover 4 is pivoted to the second open position (see FIG. 18). In the second open position, the rotation angle of the cover 4 is, for example, 180 degrees.

  Therefore, since the cover 4 is rotated between the closed position and the first open position by holding the held portion 33 by the holding portion 9a, the light body 3 is closed by the simple structure. It can be opened and closed between open positions.

  Further, in the state where the cover 4 is pressed against the pressed portion 8a, the holding force of the holding portion 9a with respect to the held portion 33 is released by applying to the cover 4 a turning force in the opening direction.

  Therefore, the cover 4 can be turned to the second open position by applying a turning force of a certain level or more to the cover 4 in a state where a part of the cover 4 is pressed against the pressed portion 8a. There is no need for a dedicated mechanism for pivoting the cover 4 from the first open position to the second open position, and the cover 4 can be simplified from the first open position to the second open position. It can be pivoted to the open position.

  In addition, the first lever 17 is provided with the operated portion 17b, and the second lever 18 is provided with the switching operation portion 18b, and the first lever 17 is operated when operating the operated portion 17b of the movement operation portion 26a of the cover 4. When the lever 17 and the second lever 18 are rotated relative to each other and moved in the same direction, the changeover switch 24 is operated by the changeover operation unit 18 b.

  Therefore, the first lever 17 and the second lever 18 are moved by the operation on the operated portion 17b of the movement operation portion 26a accompanying the rotation of the cover 4, and the on / off state of the changeover switch 24 is switched. The turning operation of the cover 4 with respect to the housing 2 and the turning on / off operation of the illumination body 3 are simultaneously performed, and it is not necessary to separately perform the turning operation and the turning on / off operation. Can be done quickly.

  Although the example in which the operated portion 17 b is provided to the first lever 17 has been described above, the operated portion may be provided to any of the first lever 17 or the second lever 18.
