Abstract

A cup holder includes a main body that includes a recess-shaped cup housing portion for housing a cup, a light source arranged on a back surface of the main body and located under the cup housing portion, and a plate-shaped light guide lens placed on a bottom surface of the cup housing portion of the main body. The main body includes a first hole and a second hole on the bottom surface of the cup housing portion. The second hole is arranged to guide light emitted from the light source to the light guide lens, and the first hole is arranged to drain liquid inside the cup housing portion.

First claim

The invention claimed is:

1. A cup holder, comprising:
a main body that comprises a recess-shaped cup housing portion for housing a cup;
a light source arranged on a back surface of the main body and located under the cup housing portion;
a plate-shaped light guide lens placed on a bottom surface of the cup housing portion of the main body; and
a mat placed on the light guide lens inside the cup housing portion,
wherein the main body comprises a first hole and a second hole on the bottom surface of the cup housing portion,
wherein the second hole is arranged to guide light emitted from the light source to the light guide lens,
wherein the first hole is arranged to drain liquid inside the cup housing portion,
wherein the mat comprises a protrusion formed on a surface facing the light guide lens,
wherein the light guide lens comprises a hole to receive the protrusion of the mat to fix the mat to the light guide lens,
wherein the main body further comprises a third hole formed on the bottom surface of the cup housing portion to avoid contact with the protrusion of the mat, and
wherein the hole of the light guide lens and the third hole of the main body are arranged to form a gap to communicate from the cup housing portion to the back surface when the protrusion of the mat are received in the hole of the light guide lens as to serve as a drain hole to drain liquid inside the cup housing portion.

2. The cup holder according to claim 1 , wherein the light guide lens comprises a protrusion formed on a surface facing the bottom surface of the cup housing portion, and
wherein the first hole is arranged to receive the protrusion of the light guide lens to fix the light guide lens to the main body and tip form a gap to communicate from the cup housing portion to the back surface when the protrusion of the light guide lens is received in the first hole.

3. The cup holder according to claim 1 , wherein the hole of the light guide lens has an arc shape at a portion on a light source side.

4. The cup holder according to claim 1 , wherein the light guide lens inclines toward the first hole.

5. The cup holder according to claim 1 , wherein the main body further comprises an annular protrusion formed on the back surface so as to surround the first hole.

6. The cup holder according to claim 1 , wherein the main body further comprises a plurality of wall-shaped protrusions formed on the back surface so as to surround the second hole.

7. The cup holder according to claim 1 , wherein the light source inclines on a side of a connector of the light source.

8. The cup holder according to claim 1 , wherein the light guide lens further comprises a groove that reflects light entering the light guide lens through a light inlet portion to collect light emitted from the light source and that changes a travel direction of the light to a region of an edge of the light guide lens that is hidden behind the holes when viewed from the light inlet portion.
