FIG. 1 shows an inner surface of a vehicle door to which the present invention is applied. In the figure, reference numeral 10 denotes a cup holder device, which is provided on the upper inner side surface of the door 1. As shown in FIG. 2, the cup holder device 10 includes a base plate 20, a cover 30, an arm 40, a holder 50, and the like, and these components are integrally formed of a soft resin.

The base plate 20 is a substantially plate-like member, and has two screw insertion holes 21 formed on both sides of the upper end as shown in FIG. Further, a pair of insertion portions 22 are formed downward at the lower portion of the rear surface of the base plate 20, and these insertion portions 22 are inserted into the holes 3 (see FIG. 4) of the door trim 2 of the door 1 from above, and screws are inserted from the front side. The base plate 20 is vertically fixed to the door 1 by screwing the base plate 4 into the nut 6 fixed to the back surface of the inner panel 5. A pair of rails 23 protrude vertically at the center of the front surface of the base plate 20, and guide rails 24 in the vertical direction are formed on both outer surfaces of the rails 23. The lower end of the guide groove 24 is opened downward, the upper part is slightly inclined forward 24b, and then the upper end is opened forward. Upper end opening 24 of the guide groove 24
In the middle of “a”, a downward regulating claw 25 for locking a regulating projection 53 of the holder 50 described later is formed. A pair of outwardly extending shafts 26
The shaft portions 26 are provided with covers 3 to be described later.
0 so as to be rotatable. At the upper end of the rail 23, a box-shaped projection 27 projecting forward is integrally formed. A lock button 28 is integrally formed on the upper edge of the base plate 20 so as to be elastically displaceable in the vertical direction. On both sides of the lower end of the lock button 28, there are formed lock claws 28a which are engaged with claws (engaging portions) 34 of a cover 30 described later and hold the cover 30 in a closed state.

The cover 30 also serves as a cup bottom receiving plate, and is integrally formed of resin so as to cover the front side of the base plate 20 so as to have a concave cross section. A bearing hole 31 into which the shaft portion 26 of the base plate 20 is rotatably fitted is formed at one end of the cover 30, and the cover 30 is moved between a closed position covering the front side of the base plate 20 and a horizontal open position. It can be opened and closed. At the same end of the cover 30, a pair of shaft support portions 32 is provided so as to be fitted with one end of an arm 40 described later. A relief portion 33 for preventing interference with the lock body 28 is cut out at the other end of the cover 30. Inside the relief portion 33, a lock claw 28a of the lock button 28 is engaged and closed. A claw 34 for holding the state is formed. At the center of the cover 30, a circular shallow recess 35 supporting the bottom of the cups C is formed.

The arm 40 is also integrally formed in a substantially U-shape with resin, and has a cover 30 at its base end (one end).
Two shaft portions 41a rotatably fitted to the shaft support portion 32 of
41b is protruded to both sides. One of the shaft portions 41a is formed to be longer than the other shaft portion 41b, and a compression coil spring 48 is attached to the longer shaft portion 41a.
Is inserted. Therefore, the arm 40 is attached to the cover 30 by fitting the long shaft portion 41a to the one bearing portion 32, compressing the coil spring 48, and then fitting the short shaft portion 41b to the other bearing portion 32. The shaft portions 41a and 41b can be prevented from coming off from the bearing portion 32. At the free end (the other end) of the arm 40, shafts 42a and 42b are provided so as to protrude inward. The shafts 42a and 42b are rotatably fitted in bearing holes 51 of the holder 50. ing. The one shaft portion 42a is formed longer than the other shaft portion 42b, and a torsion spring 49 for urging the arm 40 and the holder 50 in the opening direction A is inserted through the long shaft portion 42a. ing.

The holder 50 is for preventing the cups C placed on the cover 30 from overturning, and is integrally formed of resin into a shape that can be folded inside the arm 40.
The holder 50 of this embodiment is formed in a substantially U-shape or a substantially C-shape with one end opened. The opening at the tip of the holder 50 is formed slightly wider than the interval between the claws 34 of the cover 30. Bearing holes 51 are formed on both sides on the free end side of the holder 50, and the shaft portion 42 of the arm 40 is rotatably fitted in these bearing holes 51. A pair of columnar slide projections 52 slidably engaged with the guide grooves 24 of the base plate 20 are provided inwardly at the ends (intermediate portions) of the holder 50 opposite to the free ends. Between these projections 52, there are regulating claws 25 of the base plate 20.
The restriction protrusion 53 which engages with the projection is provided to project upward. The restricting claw 25 and the restricting projection 53 constitute a restricting means of the present invention, and the locking force thereof is set such that when a large external force acts on the holder 50 in a forward direction, it is relatively easily released.

The above-structured cup holder device 10 is assembled as follows. First, the shaft portion 26 of the base plate 20 is fitted into the bearing hole 31 of the cover 30, and the base plate 20 and the cover 30 are rotatably connected. On the other hand, the holder 50 and the arm 40 are assembled in advance,
The shafts 41 a and 41 b of the arm 40 are fitted to the shaft support 32 of the cover 30. When the cover 30 is closed while the holder 50 is folded inside the arm 40, the slide projection 52 is automatically inserted from the lower end opening of the guide groove 24, and the assembly is completed. In addition to the above-described assembling method, the slide protrusion 52 is connected to the upper end opening 2 of the guide groove 24.
4a, the regulating protrusion 53 is moved to the regulating claw 25.
, The slide projection 52 can be inserted into the guide groove 24.

When it is desired to use the cup holder device 10 as a small container, the holder 50 and the arm 40 may be removed. First, the cover 30 is opened to the fully open position, and the shaft portions 41a and 41b of the arm 40 are removed from the shaft support portion 32 of the cover 30. That is, the arm 40 is connected to the long shaft portion 41a.
If you push it to the side to compress the coil spring 48,
The short shaft portion 41b easily comes off the shaft support portion 32. Then, if the slide projection 52 of the holder 50 is pulled out from the lower end opening of the guide groove 24, the holder 50 and the arm 40 can be easily removed.

Next, the opening and closing operation of the cup holder device 10 will be described with reference to FIGS. FIG. 4 shows a state in which the cover 30 is opened, and the side edge 3 on the rear edge side of the cover 30 is shown.
6 is a boss 2 supporting the shaft 26 of the base plate 20.
9 and the lower edge of the stopper projection 20a. Therefore, the cover 30 is supported in a horizontal position,
Even if the weight of the cups C acts on the cover 30, the cover 3
0 does not bend. Further, since the arm 40 and the holder 50 are urged in the opening direction by the torsion spring 49, the slide projection 52 of the holder 50 stops at the upper edge of the guide groove 24, and is at a substantially horizontal position. Note that the arm 40 is inclined 4
Standing at 5 degrees.

When the cover 30 is turned in the closing direction, the inner surface of the cover 30 contacts the front end of the holder 50 when the cover 30 is turned by about 45 degrees, and pushes the front end of the holder 50 obliquely rearward. Therefore, the rear end (the base plate side) of the holder 50 is pushed down, and the guide groove 24 is pressed.
The slide protrusion 52 is slid downward along the guide groove 24 by utilizing the inclined portion 23b.
Accordingly, the arm 40 also rotates upward. FIG. 5 shows this state.

Further, the cover 30 is rotated in the closing direction,
When the cover 30 reaches the fully closed position, the claw 34 of the cover 30 is engaged with the lock claw 28a of the lock button 28, and the cover 30 is held in a closed state. At this time, the holder 50 is
And the holder 50 and the arm 40 are compactly stored between the base plate 20 and the cover 30. FIG. 6 shows this state.

On the other hand, when opening the cover 30 in the fully closed position, the lock button 28 exposed on the top surface of the cover 30 is pressed down. As a result, the front end side of the lock button 28 is displaced downward, and the lock claw 28a is disengaged from the claw 34 of the cover 30. Therefore, the upper end of the arm 40 tries to rotate forward by the torsion spring 49 and pushes the cover 30 in the opening direction. When the cover 30 rotates in the opening direction, the arm 40 also follows and rotates, and the slide protrusion 52 of the holder 50 slides in the guide groove 24 upward. Then, when the holder 50 rotates to the substantially horizontal position, the slide projection 52 hits the upper end of the guide groove 24 and stops, and thereafter, only the cover 30 rotates to the horizontal position.

In the above cup holder device, the cover 3
When the cups C are placed on the cover 30 in a state where 0 is opened to the horizontal position, the outer periphery of the cups C is held by the holder 50. In particular, since the holder 50 is supported from both sides by the arm 40, the base plate 20 and the holder 5
The 0 and the arm 40 have a triangular structure in a side view as shown in FIG. 4, and a very stable support structure. Therefore, the cups C can be stably held without bending or rattling even when the vehicle body vibration or inertia force is applied. Further, when the cover 30 is opened, the arm 40 rotates in the same direction as the cover 30. Therefore, only by unlocking the cover 30, the cover 30 and the arm 30 rotate smoothly, and The holder 50 also smoothly rotates to the horizontal position. Further, since the holder 50, the arm 40, and the cover 30 can be urged in the opening direction only by the spring 49 that urges the holder 50 and the arm 40 in the opening direction, the number of parts is small and the structure is very simple.

In the above-described cup holder device, when an external force is applied to the holder 50 in a state where the cover 30 is in the fully open position and the cups C are not held,
The slide projection 52, the shaft portions 41a and 41b, or the shaft portions 42a and 42b are easily damaged. If an attempt is made to reinforce these projections and shafts so as not to be easily damaged, the entire cup holder device becomes large. Therefore, in the above embodiment, when an external force is applied to the holder 50, the slide projection 52 of the holder 50 is detached from the guide groove 24 to prevent the projection and the shaft from being damaged. That is, in FIG. 4, the tensile to the downward force F ₁ and the front above a certain value to the holder 50 a force F
_{When 2} acts, the regulating projection 53 of the holder 50 comes off the regulating claw 25 of the base plate 20, and the sliding projection 52 comes off from the upper end opening 24a of the guide groove 24 (FIG. 4).
Is indicated by a two-dot chain line). For this reason, no excessive force acts on the slide protrusion 52, the shaft portions 41a, 41b, 42a, 42b, and the like, and damage can be prevented. When reassembling, as described in the above-described assembling method, if the cover 30 is closed while the holder 50 is folded inside the arm 40, the slide protrusion 52 is automatically inserted from the lower end opening of the guide groove 24. Can be easily assembled.

The present invention is not limited to the above embodiment, and it goes without saying that various modifications can be made as described below. FIG. 7 shows another embodiment of the regulating means. In this embodiment, a protrusion 24c protruding inward is formed at the upper end opening 24a of the guide groove 24 so that the slide protrusion 52 does not come out of the upper end opening 24a freely. Also in this case, when an external force acts on the holder 50 in the forward direction, the slide projection 52 comes off from between the projections 24c, so that an unreasonable load is not applied to the holder 50 or the arm 40.

In the above embodiment, the arm 40 is formed in a substantially U-shape so as to support the both sides of the holder 50, but the arm may be formed of two link members. in short,
The shape is not limited as long as the shape does not interfere with cups placed on the cover and can be stored in the cover together with the holder in a foldable manner. When the arm has a substantially U-shape, there is an advantage that the right and left inclination of the holder can be regulated and the support rigidity is increased.

The arm 40 is connected to the shaft support 3 of the cover 30.
2 is pivotally supported in a vertically rotatable manner, but may be pivotally supported by the base plate 20 instead of the cover 30. Further, the arm may be supported coaxially with the support portion of the cover.

In the above embodiment, the lock button 28 is formed integrally with the base plate 20 as the lock portion. However, a lock button may be formed on the cover 30, and a separate lock button may be formed on the base plate 20 or the cover 30.
It may be attached to. Lock button 28 as in the embodiment
When the lock claws 28a are formed on both sides of the cup holder, it is possible to obtain an upper push type and thin cup holder device.

When holding a large cup, the holder 50
In some cases, the slide projection 52 cannot be held in a state where the slide projection 52 is engaged with the guide groove 24. On the other hand, if the slide projection 52 is removed from the guide groove 24, the arm 40 pivots to the horizontal position, so that a force in the falling direction is applied to the cup. Therefore, a torsion spring may be inserted into the shaft portion 41a of the arm 40 in place of the coil spring 48, so that the arm 40 is always provided with upward turning power. In this case, since the holder 50 and the arm 40 are lifted upward by the torsion spring, the cup can be prevented from tipping over.

The vehicle cup holder device of the present invention is not limited to the inside of a door, but may be employed in any portion such as the back of a seat or the inside of a vehicle body.

[0028]

As is apparent from the above description, according to the present invention, since the lock button is a push system from above,
Since the operation is simple and the lock button is formed integrally with the base plate, the number of parts is small. In addition, since the lock claws are formed on both sides of the lock button, the engaging portions of the cover that engage with the lock claws may be formed on the portions facing the both sides of the lock button. Can be made thin, and a thin cup holder device as a whole can be obtained.
