## Background
BACKGROUND OF THE INVENTION AND RELATED ART STATEMENT
The present invention relates to an improvement of a cup holder device provided, for example, inside a vehicle compartment. In the cup holder device, a length of a placement portion can be extended in a sliding direction of a holder main member to place and hold a cup securely.
Conventionally, a cup holder device includes a placement portion arranged under a cup insertion hole of a holder main member for placing a cup. The placement portion is folded or unfolded while the holder main member slides.
For example, Japanese Patent No. 2691424 has disclosed a placement portion composed of a tray 4 and a guide arm 5 (column 4, lines 7-15, FIG. 1). The tray 4 is formed in a dogleg shape, and is composed of an arm portion 4a and a tray portion 4b (column 4, lines 24-28, FIG. 1). A table 3 supports the arm portion 4a through a supporting axis 8 (column 4, lines 24-28, FIG. 1).
A guide axis 9 is provided in the tray portion 4b, and a long guide hole 5a of the guide arm 5 supports the guide axis 9 to be able to slide (column 4, lines 33-35, FIG. 1). The table 3 supports the guide arm 5 through a supporting axis 10 (column 4, lines 36-38, FIG. 1).
Japanese Utility Model No. 2510389 has disclosed a placement portion composed of an arm 16 and a receiving tool 17 (column 3, line 48 to column 4, line 6, FIG. 1). A long hole 13a of the main member 13 supports the arm 16 through a holder bar 14 to be able to slide (column 3, lines 40-47, FIG. 1). The arm 16 and the receiving tool 17 are connected through a link 19 (column 4, lines 4-6, FIG. 1). The table 3 supports the receiving tool 17 as shown FIG. 1 in Japanese Patent No. 2691424.
However, in the above-mentioned cup holder devices, the placement portion for placing the cup bottom is short, thereby making it difficult to hold the cup stably.
Therefore, the present invention has been proposed to solve the problems with conventional technology, and an object of the present invention is to provide a cup holder device, in which a length of a placement portion can be extended in a sliding direction of a holder main member to place and hold the cup securely.
Further objects and advantages of the invention will be apparent from the following description of the invention.

An operation of the cup holder device 10 with the configuration mentioned above will be explained next. In order to store the holder main member 50 inside the attachment base 30, the handle 52 is pushed into the attachment base 30 as shown in FIG. 5. When the holder main member 50 is pushed in, the holder main member 50 retracts relative to the slider 40 as shown in FIG. 5. At this time, the slider 40 pushes a slant surface of the first arm 100 in the holder arm 60, and the holder arm 60 is folded and stored inside the slider 40, as shown in FIGS. 5 and 6.
At the same time, the slider 40 pushes the side arm 54 in the holder main member 50, and the side arm 54 is pulled in the cup hole 53 as shown in FIG. 8. When the handle 52 is further pushed into the attachment base 30, the holder main member 50 pushes the slider 40 to retract inside the attachment base 30, as shown in FIGS. 6 and 7.
The cam groove 72 of the holder main member 50 engages the lock pin 71 at a backside of the attachment base 30 (not shown). The lock pin 71 is then locked inside the cam groove 72, so that the slider 40 and the holder main member 50 are locked in the stored position inside the attachment base 30 as shown in FIG. 7. At this time, the slider 40 pushes the pushing member 80 inside the attachment base 30 to restore the urging force (not shown).
In order to pull out the holder main member SO from the stored state, the handle 52 is slightly pushed into the attachment base 30. When the handle 52 is pushed (not shown), the lock pin 71 disengages from the cam groove 72, and the slider 40 is pushed, outwardly through the opening 21 of the attachment base 30 by the urging force of the pushing member 80. Then, the handle 52 of the holder main member 50 is pulled out with a finger as shown in FIGS. 1-3.
When the holder main member 50 is pulled out, the holder arm 60 unfolds or expands downward by the spring force of the first urging member 131 and the second urging member 132, as shown in FIGS. 1 and 2. At the same time, the side arm 54 projects outwardly toward the side of the holder main member 50 by the spring force of the spring, and the circular container holding portion 51 is formed to be ready to receive the cup C.
The present invention with the above configuration provides the following effects. According to the first aspect of the invention, the placement portion for placing the cup is divided into the two parts, and can be folded when the holder main member is stored. The placement portion can be unfolded to hold the cup stably when the holder main member is pulled out without impairing the storability.
According to the second aspect of the invention, the configuration of the first link portion between the first arm and the second arm is simplified. According to the third aspect of the invention, the configuration of the second link portion between the holder main member and the third arm is simplified. According to fourth aspect of the invention, the holder arm is smoothly unfolded from the folded state with the urging force of the urging means.
According to the fifth aspect of the invention, the configuration of the urging means is simplified. According to the sixth aspect of the invention, the slider is provided between the attachment base and the holder main member so that the drawing length of the holder main member is extended relative to the attachment base.
While the invention has been explained with reference to the specific embodiments of the invention, the explanation is illustrative and the invention is limited only by the appended claims.
