Is turned to a horizontal position to be used, and when folded after use, the ring b is closed first, and then the lid a is closed and stored.

However, in this cup holder, since the lid a and the ring b must be operated separately, there is a problem that the operation is troublesome.

In order to solve such a problem, a cup holder in which the lid and the ring are rotated in conjunction with each other is disclosed in, for example, Japanese Utility Model Publication No. 4-39071 and Japanese Utility Model Publication No. 8-435.
No. 6, for example.

[0006] The cup holder described in Japanese Utility Model Publication No. 4-39071 discloses a lid plate in which a cup body receiving ring is rotatably supported on an inner side in a closed state and an upright state with respect to a cup bottom receiving plate. A rotatable bearing is provided on one side of the cup bottom receiving plate so that a locking portion for locking the lid plate and the cup bottom receiving plate in a closed state is provided, and a crank portion is provided on a rotating shaft portion of the cup body receiving ring. A plate-shaped lid opening member that slides in the direction of the cup bottom receiving plate is provided inside the lid plate, and the lid opening member is engaged with the crank portion so that the cup body receiving ring can be raised and lowered with respect to the lid plate. A cam portion for rotating is formed, and an elastic member for urging the lid opening member in the direction of the cup bottom receiving plate is provided, and the lid opening member is brought into contact with one end of the lid opening member on the cup bottom receiving plate and the lid opening member is moved in the direction of the cup bottom receiving plate. A pushing cam projection is provided, and the stopper is Which it was so as to rotate the Do受 ring has the effect of opening and closing the cup holder can be made compact with enable one-touch.

[0008]

However, the cup holder described in the former publication has a lid opening member that engages with the crank portion of the cup body receiving ring, an elastic member that urges this in the direction of the cup bottom receiving plate, Since it is composed of a cam that abuts one end of the lid opening member and pushes the lid opening member toward the cup bottom receiving plate, the structure is complicated and the number of parts is large. In addition, when the cup holder is stored, a large force acts on the lid opening member and the cam projection when the cup holder is stored.

Further, the cup holder described in the latter publication has a more complicated structure than the cup holder,
There is a possibility that a large number of man-hours may be required for the manufacture, and the interlocking mechanism between the base and the side support member is exposed even in the housed state, so that the appearance may be impaired.

SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and has a simple structure, is easy to assemble, and can be easily installed in, for example, a pillar trim having a small depth. It is intended to provide a holder.

[0011]

SUMMARY OF THE INVENTION Therefore, according to the present invention, the base end of the ring is pivotally mounted on the upper part of the case having an open front surface so as to be rotatable in the vertical direction, and is mounted on the lower part of the case. , The base end side of the lid is pivotally connected in the up and down direction, and the coil part on one end side of a spring having a coil part substantially at an intermediate portion between both ends is fitted to the pivotal connection part of the ring to raise the ring. Direction, and the other end of the coil is fitted to the pivotal connection of the lid to urge the lid downward. Is set smaller than the urging force of the coil section.

With this configuration, when the lid is rotated downward from the storage state to the use state, the lid is rotated with a small force by the urging force of the coil portion on the lid side, and at the same time, the coil on the ring side is rotated. The ring is automatically rotated to the use position by the urging force of the part. For this reason, it can be set to a use state by a simple operation.

In the stored state, the ring is in the case,
Then, the lid is stored at a position where the lid closes the opening of the case. For this reason, it can be configured to be thin, whereby it can be easily installed even in a place with a small depth such as a pillar trim, and since the spring and the like are not exposed to the outside in the stored state, the appearance is not spoiled.

Furthermore, since the lid and the ring can be opened and closed in conjunction with one spring, the structure is simpler and the number of parts is smaller than in the conventional case.
An inexpensive cup holder can be provided.

According to a second aspect of the present invention, in the configuration of the first aspect of the present invention, the spring is arranged such that the spring is longer than the distance from the ring-side coil to the substantially middle coil.
The configuration is such that the distance from the coil portion on the lid side to the substantially middle coil portion is set large.

With this configuration, when the lid is rotated upward from the use state to the storage state, the ring is first stored to a predetermined position, and then the lid is further rotated, whereby the ring is pushed by the lid and the ring is pushed. It is stored in the case. Therefore, the ring can be stored simply by rotating the lid, and the storing operation can be performed conveniently.

According to a third aspect of the present invention, in the configuration of the first aspect of the present invention, the spring is configured such that an opening angle of a ring-side coil portion and an opening angle of a lid-side coil portion are different from each other. The configuration is such that it is set slightly smaller than the respective opening angles in the free state.

With such a configuration, the biasing force of the coil portion is constantly acting on the lid and the ring in the state where the ring and the lid are in the use position. For example, it is possible to prevent occurrence of backlash and generation of abnormal noise.

Further, the invention according to claim 4 is configured such that the tip of the ring is curved downward in use.

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described in detail with reference to the drawings shown in FIGS.

FIG. 1 is a perspective view of a cup holder showing an embodiment of the present invention in a used state, FIG. 2 is a perspective view of a stored state, FIG. 3 is a sectional view of a used state, and FIG. 4 is a sectional view of a stored state. is there.

In the drawing, 1 is a flat rectangular case,
The case 1 has an opening 1a on the front surface and a frame 1b on both sides, so that the case 1 can be easily installed in a place with a small depth such as a pillar trim of a vehicle.

Reference numeral 2 denotes a flat lid which is pivotally attached to the lower portion of the case 1 so as to be freely foldable. When the lid 2 is folded, the lid 2 is formed in such a size that the opening 1a of the case 1 can be closed, and a support shaft 2a protruding from both lower ends on one end side is provided on the lower inner surface of the case 1. The other end is rotatable about the support shaft 2a in the vertical direction. When the lid 2 is opened, the lid 2 is held at a substantially horizontal position by the lower side of the case 1 as shown in FIG.

FIG. 3 shows an end of the lid 2 on the side of the support shaft 2a.
And a curved portion 2 curved in a partial arc shape as shown in FIG.
b when the lid 2 is opened and closed.
Of the case 1 is in sliding contact with the upper surface of the lower side of the case 1. Further, a slit 1c through which the curved portion 2b can pass when the lid 2 is opened is opened in a lower portion of the case 1.

A coil portion 3b of a spring 3 composed of a helical spring is fitted on one of the left and right support shafts 2a of the lid 2 and on the right support shaft 2a in FIG. 1 in this embodiment. Have been combined.

The springs 3 have coil portions 3a, 3a at three positions at both ends and a position slightly above the middle portion.
b, 3c, and is formed substantially M-shaped as a whole. The end on the side of the coil portion 3b is locked on the upper surface of a spring receiving rib 2c protruding along the side edge of the lid 2, so that the lid 2 is fixed to the coil portion 3b.
A force in the opening and releasing direction (direction of use position) can be given by the spring force of b.

A coil portion 3c provided substantially at an intermediate portion (slightly above the intermediate portion) of the spring 3 projects forward from inside the case 1 when the lid 2 is opened. A coil portion 3c formed on the other end of the spring 3 is fitted to one support shaft 4a of a ring 4 described later.

The ring 4 supports the body of a cylindrical container (not shown) whose bottom is supported by the lid 2. The support shaft 4a is formed at both ends on the base end side of the ring 4, and these support shafts 4a are fitted into shaft holes 1e formed in the upper portion of the case 1, and the ring 4 is vertically moved around the support shaft 4a. It is freely rotatable. In addition, the ring 4
As shown in FIG. 1, a circular hole 4b having a diameter slightly larger than the outer diameter of a container (not shown) is opened substantially at the center of a plate body whose front end side is slightly curved downward.

The end of the ring 4 on the side of the coil portion 3a fitted to one of the support shafts 4a is locked to the lower surface of the ring 4, whereby the ring 4 is moved by the spring force of the coil portion 3a. A force in the opening direction (direction of the use position) can be given. In the figure, reference numeral 5 denotes a lock pin for holding the lid 2 in a closed state.

Next, the operation of the cup holder having such a configuration will be described. In the housed state where the lid 2 and the ring 4 are folded, as shown in FIG. 4, the ring 4 is housed in the case 1, and the opening 1 a of the case 1 is closed by the lid 2.

Therefore, in the above stored state, the ring 4
The spring 3 is not exposed to the outside, and the beauty of the cup holder and its surroundings is not impaired.

To change the cup holder from the stored state to the used state, first, the lock pin 5 is pressed to release a predetermined lock, and then the lid 2 is pivoted downward about the support shaft 2a.

At this time, since the lid 2 is urged in the opening direction by the coil portion 3b of the spring 3, it can be opened with a light force. Also, by opening the lid 2,
The ring 4 constrained by the lid 2 immediately before that is rotated upward about the support shaft 4a by the urging force of the coil portion 3a.

Thereafter, as shown in FIG. 3, the lid 2 is stopped at a substantially horizontal position by contacting the outer surface with the upper surface of the lower side of the case 1 and the rear end with the vertical surface of the case 1, respectively. The upper surface of the ring 4 comes into contact with the lower surface of the upper side of the case 1 and is stopped at a substantially horizontal position, so that the ring 4 can be used. At the same time, the coil portion 3c formed substantially in the middle of the spring 3 projects forward from inside the case 1 so that the angle of the coil portion 3a is θ1, the angle of the coil portion 3b is θ2, and the coil 3c Becomes an angle θ3, and the spring 3 approaches a free state and is restored to a substantially M shape.

Here, the coil portion 3 in the free state of the spring 3 (in a no-load state before being mounted on the cup holder).
a and the opening angles θ6, θ8 of the coil portion 3b are θ6 = θ
1 + Δθ, θ8 = θ2 + Δθ, use the angle θ
It is set in advance to an angle obtained by adding a small angle Δθ to 1, θ2. That is, in use, the opening angle θ1 of the coil portion 3a on the lid 2 side and the opening angle θ2 of the coil portion 3b on the ring 4 side are smaller than the respective opening angles θ6 and θ8 in the free state of the spring 3 by a small angle Δθ. It is set to be. For this reason, during use, the urging force due to Δθ always acts on the lid 2 and the ring 4, thereby causing backlash between the case 1 and the lid 2 and the ring 4 at the time of running of the vehicle, etc. It is possible to prevent the occurrence of troubles such as occurrence.

On the other hand, when the lid 2 and the ring 4 are changed from the used state to the stored state, the distal end side of the lid 2 is rotated upward.

At this time, the spring force of the coil portion 3c formed substantially in the middle of the spring 3
Since the coil portions 3a and 3b are set to be smaller than the coil portions 3a and 3b, the coil portions 3a and 3b are retracted until only the coil portion 3c contacts the vertical surface of the case 1 while maintaining the angles θ1 and θ2. Thereby, the tip side of the ring 4 is rotated downward.

The coil portions 3a to 3c
Since the distance L1 to L1 and the distance L2 from the coil portion 3b to the coil portion 3c are set in advance to L1 <L2,
When the lid 2 is rotated, the rotation angle of the ring 4 is larger than the rotation angle of the lid 2. Thereby, first, the ring 4 is folded to the position shown by the broken line in FIG.
The lid 2 is sequentially rotated upward as shown by a broken line in FIG. 3, and the inner surface of the lid 2 abuts on the tip of the ring 4.

Thereafter, when the lid 2 is further rotated upward, the tip of the ring 4 is pushed into the case 1 by the inner surface of the lid 2, and the lid 2 closes the opening 1 a of the case 1. The state shown in FIG. At the same time as the lid 2 closes the opening 1a of the case 1, the lock pin 5 locks the lid 2 and keeps the lid 2 in the storage position. For this reason, the lid 2 and the ring 4 can be stored simply by rotating the lid 2 upward.

When the lid 2 is pushed up when operating from the use state to the housed state, the opening angle θ1 of the coil portion 3a becomes θ1 + Δθ, and thereafter the tip of the ring 4 comes into contact with the inner surface of the lid 2. Later, it decreases again to θ1.

As a result, when the lid 2 is rotated downward from the storage state to the use state, the lid 2 is rotated with a light force by the urging force of the coil portion 3b on the lid 2 side, and at the same time, the ring The ring 4 is automatically rotated to the use position by the urging force of the coil portion 3a on the fourth side. For this reason, it can be set to a use state by a simple operation.

In the housed state, the ring 4 is housed in the case 1, and the lid 2 is housed in a position to close the opening 1 a of the case 1. For this reason, it can be configured to be thin, whereby it can be easily installed even in a place with a small depth such as a pillar trim, and in a stored state, the spring 3 and the like are not exposed to the outside, so that the appearance is not spoiled.

Further, since the lid 2 and the ring 4 can be opened and closed in conjunction with one spring 3, the structure is simpler than the conventional one, the number of parts is reduced, and an inexpensive cup holder is provided. can do.

The distance between the coil 3b on the lid 2 and the coil 3c in the middle is larger than the distance between the coil 3a on the ring 4 and the coil 3c in the middle. Due to the large setting, when the lid 2 is rotated upward from the use state to the stored state, the ring 4 is first stored to a predetermined position, and then the lid 2 is further rotated to be pushed by the lid 2. The ring 4 is stored in the case 1. Therefore, the ring 4 can be stored simply by rotating the lid 2, and the storing operation can be performed conveniently.

The spring 3 has an opening angle of the coil portion 3a on the ring 4 and a coil portion 3b on the lid 2 side.
Are set to be slightly smaller than the respective opening angles of the springs 3 in the free state, so that the ring 4 and the lid 2 are in the use position and the coil portions 3b, 3a Since the urging force is constantly acting on the lid 2 and the ring 4, it is necessary to prevent rattling between the case 1 and the lid 2 and the ring 4 during running of the vehicle, thereby preventing noise from occurring. Can be.

[0046]
