Abstract

An attachment structure for installing a lighting device on an attachment target, includes a hole formed in a bottom surface of the attachment structure for letting light from the lighting device pass through the hole, and a plurality of ribs formed around the hole. The plurality of ribs are substantially flush with each other in a lighting device placement area configured to receive a bottom surface of the lighting device, so that the lighting device is positioned with respect to the bottom surface of the attachment structure in a height direction of the lighting device.

First claim

The invention claimed is:

1. An attachment structure for installing a lighting device on an attachment target, comprising:
a hole formed in a bottom surface of the attachment structure for letting light from the lighting device pass through the hole; and
a plurality of ribs formed around the hole,
wherein the plurality of ribs are substantially flush with each other in a lighting device placement area configured to receive a bottom surface of the lighting device, so that the lighting device is positioned with respect to the bottom surface of the attachment structure in a height direction of the lighting device, and
at least one of the plurality of ribs makes contact with the hole and extends from the hole in a plan view.

2. The attachment structure according to claim 1 , wherein a length of the at least one of the plurality of ribs positioned adjacently to the hole is smaller than a length of another one of the plurality of ribs that is positioned away from the hole.

3. The attachment structure according to claim 1 , further comprising a wall and a wall-shaped light source support that support side surfaces of the lighting device and are arranged upstanding from the bottom surface of the attachment structure, wherein the wall and the light source support are connected to each other.

4. The attachment structure according to claim 1 , further comprising a wall that supports a side surface of the lighting device and is arranged upstanding from the bottom surface of the attachment structure, wherein the wall is joined to the at least one of the plurality of ribs positioned in contact with the hole.

5. The attachment structure according to claim 1 , further comprising:
a wall-shaped connector support supporting a connector of the lighting device; and
a wall supporting a portion of the side surface of the lighting device,
wherein the wall-shaped connector support and the other wall stand on the bottom surface of the attachment structure.

6. The attachment structure according to claim 5 , wherein the wall-shaped connector support is joined to the another one of the plurality of ribs formed around the hole that is positioned away from the hole.

7. The attachment structure according to claim 5 , wherein the wall is joined to the other one of the plurality of ribs formed around the hole that is positioned away from the hole.

8. The attachment structure according to claim 5 , wherein the wall-shaped connector support and the wall are respectively supported by another rib extending in a direction along the shorter side of the attachment structure.

9. The attachment structure according to claim 1 , wherein the attachment structure is applied to a door lining attached to a passenger compartment side of a door panel of a vehicle, the door lining comprising:
a door arm rest disposed in a central region of the door lining along a longitudinal direction of the vehicle;
a lower region downward of the door lining;
a door pocket for accommodating articles therein, the door pocket being disposed in the lower region; and
a speaker housing for housing a speaker, the speaker housing being disposed in the lower region,
wherein the door pocket is made partly concave to provide a cavity for accommodating articles therein, and
an upper surface of the door pocket of the door lining of the vehicle includes the attachment structure for installing the lighting device on a back surface side of the door lining.

10. An attachment structure for installing a lighting device on an attachment target, comprising:
a hole formed in a bottom surface of the attachment structure for letting light from the lighting device pass through the hole; and
a plurality of ribs formed around the hole,
wherein the plurality of ribs are substantially flush with each other in a lighting device placement area configured to receive a bottom surface of the lighting device, so that the lighting device is positioned with respect to the bottom surface of the attachment structure in a height direction of the lighting device,
at least one of the plurality of ribs is positioned adjacently to the hole, and
the attachment structure has a shorter side and a longer side, and the plurality of ribs extend in a direction along the shorter side of the attachment structure.

11. The attachment structure according to claim 10 , wherein a length of the at least one of the plurality of ribs positioned adjacently to the hole is smaller than a length of another one of the plurality of ribs that is positioned away from the hole.

12. The attachment structure according to claim 11 , further comprising a wall and a wall-shaped light source support that support side surfaces of the lighting device and are arranged upstanding from the bottom surface of the attachment structure, wherein the wall and the light source support are connected to each other.

13. The attachment structure according to claim 10 , further comprising a wall that supports a side surface of the lighting device and is arranged upstanding from the bottom surface of the attachment structure, wherein the wall is joined to the at least one of the plurality of ribs positioned in contact with the hole.

14. The attachment structure according to claim 10 , further comprising:
a wall-shaped connector support supporting a connector of the lighting device; and
a wall supporting a portion of the side surface of the lighting device,
wherein the wall-shaped connector support and the other wall stand on the bottom surface of the attachment structure.

15. The attachment structure according to claim 14 , wherein the wall-shaped connector support is joined to the another one of the plurality of ribs formed around the hole that is positioned away from the hole.

16. The attachment structure according to claim 14 , wherein the wall is joined to the other one of the plurality of ribs formed around the hole that is positioned away from the hole.

17. The attachment structure according to claim 14 , wherein the wall-shaped connector support and the wall are respectively supported by another rib extending in a direction along the shorter side of the attachment structure.

18. The attachment structure according to claim 10 , wherein the attachment structure is applied to a door lining attached to a passenger compartment side of a door panel of a vehicle, the door lining comprising:
a door arm rest disposed in a central region of the door lining along a longitudinal direction of the vehicle;
a lower region downward of the door lining;
a door pocket for accommodating articles therein, the door pocket being disposed in the lower region; and
a speaker housing for housing a speaker, the speaker housing being disposed in the lower region,
wherein the door pocket is made partly concave to provide a cavity for accommodating articles therein, and
an upper surface of the door pocket of the door lining of the vehicle includes the attachment structure for installing the lighting device on a back surface side of the door lining.
