Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening / closing device capable of opening and closing a lid of a vehicle console box and a lid rotatably attached to an opening of various box bodies from two directions.

[0002]

2. Description of the Related Art A device for opening and closing a lid of an automobile console box from two directions is disclosed in, for example, Japanese Patent Laid-Open No. 5-3384.
The one shown in Japanese Patent Publication No. 96 has been already proposed. Although not specifically shown, the conventional opening / closing device is provided with a pair of left and right operation buttons, which operate independently, on the left and right side portions of the lid side so as to be movable. A pair of hinge pins protruding and retracting from the front and rear end surfaces of the lid are individually connected to each operation button, and one lock shaft is provided on the back side of the pair of operation buttons, and in the lower surface concave portion of each operation button. The locking means for preventing the return of the operation button when it is pressed is individually provided. Even in this case, similarly to the conventional one, the pair of left and right operation buttons and the pair of hinge pins on each side are both urged outward by the spring pressure of the compression coil spring. .
Further, with respect to the box main body side, shaft holes are individually provided on both front and rear sides of the opening edge so as to project and retract the tip portions of the left and right hinge pins.

Then, when the lid is closed,
When rotating the lid to the left to open the opening of the box body, push the right operation button inward against the bias spring pressure to move the operation button. In conjunction with this, the pair of hinge pins on the right side will disengage from the corresponding axial holes in the box body against the biasing spring pressure and will be completely submerged inside the lid. It is allowed to rotate to the left with a pair of hinge pins inserted in the shaft holes of the box body as rotation axes.

At this time, the operation button on the right side, which is pressed inward, is placed in the locked state in which the locking means prevents the operation button from returning to the original urging position. It is no longer necessary to keep pressing, and the lid rotation operation is convenient, and the left operation button is prevented from being accidentally pressed inward due to the presence of the lock shaft. Therefore, there is no concern that the entire lid will fall off from the box body side due to an erroneous operation.

When closing the lid that opens the opening of the box body by rotating to the left, conversely, rotate the pair of hinge pins that engage the lid in the shaft hole on the left side. When the lid is pressed to the edge of the opening of the box body by rotating it to the right as an axis, the locked state of the right operation button by the above-mentioned locking means is automatically released this time, so the right operation button Is allowed to return to its original urging position by its urging spring pressure, and at the same time, in conjunction with this,
The pair of hinge pins on the right side are also re-engaged with the corresponding shaft holes of the box body by the biasing spring pressure thereof, so that the lid is closed.

However, such a conventional opening / closing device is an organic combination of the above-mentioned lock means and lock shaft,
Although it is convenient to rotate the lid and prevent the lid from accidentally falling off from the box body,
For this purpose, in addition to the lock shaft, it is a condition that a pair of left and right operation buttons and their locking means are all independent parts that operate independently of each other. As the number of these independent components has increased, the accessory structure associated therewith has become uncomfortable.

Therefore, the applicant tried to develop the following opening / closing device in view of the inconvenience of the conventional opening / closing device. In this development device, a pair of left and right operation buttons are integrally connected to both ends of a moving body having stopper protrusions to constantly urge the moving body to the centering position by the spring pressure of a compression coil spring, while A check lever is pivotally supported at a position facing the stopper protrusion of the body so that one end of the check lever faces the stopper protrusion side.
The other end of the check lever is exposed from the inside of the window opened in the lid, and one end of the check lever is pressed by the spring pressure of the torsion spring until the other end comes into contact with the bottom of the window. In addition to being biased upward, both ends of the moving body are connected to hinge pins on each side.

Therefore, under the developed apparatus, when the lid is closed, the other end of the check lever, which faces the outside from the window, interferes with the box body side and one end of the check lever is pressed by the spring. By swinging downward against the position, the stopper protrusion of the moving body is positioned above one end of the check lever, and the moving body is allowed to move to the centering position together with the pair of operation buttons. When opening the lid, release the interference with the box body at the other end, swing one end of the check lever upward with the spring pressure of the torsion spring, and move it from the centering position to the one end of the check lever. By engaging the stopper protrusion of the moved moving body, the moving body can be locked in place against the biasing spring pressure, so that the number of parts can be reduced compared to the conventional one.
It can contribute to the simplification of the device itself.

In addition, when closing the lid after opening it,
If you press the lid against the box body side, the other end of the check lever will interfere with the box body side again.
One end of the check lever swings downward against the spring pressure of the torsion spring to release the engagement with the stopper protrusion. As a result, the moving body is allowed to return to the centering position by the spring pressure of the compression coil spring, but the hinge pin on the closing side is still engaged with the shaft hole of the box body. Since the hinge pin on the opening side is engaged again with the corresponding shaft hole of the box body in conjunction with the return of the moving body, the engagement state of the hinge pin on the left and right sides with respect to the shaft hole is guaranteed.

[0010]

However, when the moving body 100 starts to move toward the centering position under such a development apparatus, if the force for pressing the lid L to the fully closed position is weakened, as shown in FIG. As shown in, one end 1 of the check lever
02 swings upward due to the spring pressure of a torsion spring (not shown), and the upper surface of the one end portion 102 of the check lever is caught on the lower surface of the stopper projection 101 along with the spring pressure of the torsion spring. Then, in this state, both 101 and 10
When the friction coefficient of the relative sliding surface of No. 2 is μ, the spring pressure of the torsion spring is F1, and the spring pressure of the compression coil spring is F2, if the relationship of F1> * μ> F2 holds, the moving body 1
00 is locked in place and prevented from returning to the centering position, which also prevents the hinge pin on the open side from being able to engage the corresponding shaft hole, resulting in a complete closure of the lid. The state cannot be obtained.

Further, in this state, the one end portion 102 of the check lever and the stopper projection 101 are not completely engaged, but the upper surface of the one end portion 102 and the stopper projection 1
Since the lower surface of 01 is only hooked, it becomes possible to move the moving body 101 in either direction by pressing the pair of operation buttons.

Therefore, for example, as shown in FIG. 13, the lid L is slightly rotated upward from the above state by an angle θ to a position where the hinge pin 104 on the opening side is separated from around the shaft hole 103 of the box body B. , At this position, when the operation button 106 on the closing side is pressed, the stopper protrusion 1
Since 01 does not engage with the one end 102 of the check lever, the moving body 100 moves in the pressing direction together with the operation button 106.

When the moving body 100 moves, this time, the hinge pin 105 on the closing side is disengaged from the corresponding shaft hole 103, and at the same time, the hinge pin 104 on the opening side is extended outward. As described above, since the hinge pins 104 on the opening side cannot be engaged with the shaft holes 103 because they are separated from the corresponding shaft holes 103, as a result, the left and right hinge pins 104 are not inserted.
Since all of 105 come off from the corresponding shaft holes 103, the situation where the lid L falls off from the box body B may occur.

[0014]

However, the shape of the shaft hole (concave hole portion) 3 is not limited to the through-hole shape, and any shape can be used as long as the chamfered tip portions 20b and 21b of the hinge pins 20 and 21 described later can be engaged. It may be concave, but at least regardless of its size, the hinge pin 20.
It is assumed that the chamfered tip end portions 20b and 21b of 21 have a contour edge 3a with which they can elastically abut.

On the other hand, as for the lid L side which is rotatably attached to the opening of the box body B, as shown in FIG.
An area 5 in which a moving body (link means) 15 to be described later is mounted so as to be movable in the left-right direction is defined near the front portion of the rectangular substrate 4 formed of synthetic resin, and the area 5 is left and right approximately at the center. The holding block 6 having the guide port 6a is provided, and the compression coil spring (first urging means) 7 is housed in the holding block 6.

In addition, a check lever (control means) 8 having a beak shape is provided in the vicinity of one side of the holding block 6 with a swing shaft 8c.
The one end 8a of the check lever 8 is exposed to the holding block 6 side, and the other end 8b is opened to the front wall side of the substrate 4 by swingingly supporting it via a support wall 9. The one end 8a of the check lever 8 is twisted by the torsion spring (second biasing means) 11 until it is exposed from the inside of the window 10 to the outside and the other end 8b contacts the bottom of the window 10. It is configured to urge upward. As shown in FIG. 8, vertical surfaces 12 are formed on both ends of the lower end 8a of the check lever 8 and tapered surfaces 13 continuous with the vertical surfaces 12 are formed on both sides of the upper part. Further, the one end portion 8a is supported via the guide slit (side support portion) 14 formed on the holding block 6 side of the support wall 9.

Further, the above-mentioned moving body 15 is an integrally molded product of synthetic resin having a plate-like body having a narrow intermediate portion and wide end portions, but in the present embodiment, A pair of left and right operation buttons (operation means) 16A ・ 16 on both ends of the wide width
B is integrally connected, and a plate-like stopper protrusion (control means) 17 is provided on the central side surface facing the check lever 8 in the narrow intermediate portion, and the guide port of the holding block 6 is provided on the lower surface of the intermediate portion. 6a, a pair of leg pieces 18 that interfere with the compression coil spring 7 are formed, and a pair of cam grooves composed of a C-shaped restricting portion 19a and a parallel non-restricting portion 19b at both ends of the wide portion. (Linking means) 19 is formed to face each other.

It should be noted that the moving body 15 is composed of the opposed cam grooves 1
In the state where the followers 20a, 21a of the pair of long and short hinge pins 20, 21, which are present on each side in 9 are fitted, they are mounted so as to be movable in the left and right direction in the area 5 of the substrate 4 described above. In this case, the long and short hinge pins 20 and 21 existing on each side can be moved back and forth through the guide members 22 which are arranged on both sides of the area 5 and the decorative frame 23. Will be supported by.
In addition, the tips 20b and 21b of the long and short hinge pins 20 and 21
Shall be chamfered.

When the lid L is closed, the other end 8b of the check lever 8 contacts the upper edge of the front bracket 2A, and the one end 8a resists the spring pressure of the torsion spring 11. The moving body 15 is allowed to move to the centering position by positioning the stopper projection 17 of the moving body 15 above the one end portion 8a due to the forcible swinging downward. Is moved to either the left or right side by pressing the operation button 16A or 16B,
When the other end portion 8b is released from contact with the upper edge portion of the front bracket 2A by rotating the upper end portion a little upward, this time, the one end portion 8a of the one end portion 8a swinging upward by the spring pressure of the torsion spring 11 is released. The side surface is engaged with the stopper projection 17 and locked in place.

In addition, the moving body 15 is operated by the operation button 16A or 1
When it is moved to the left or right by the pressing operation of 6B, the pair of long and short hinge pins 20 and 21 existing on the pressing side.
Will move toward each other due to the action of the V-shaped restricting portions 19a of the opposing cam grooves 19, but the pair of long and short hinge pins 20.
Reference numeral 1 denotes a non-restricting portion 1 having a parallel shape of the opposing cam grooves 19.
Due to the action of 9b, they do not move in the directions approaching each other.

In the figure, 24 is a support hole for supporting the chamfered tip 20b of the short hinge pin 20 on each side.
Corresponding to the shaft hole 3 of the front bracket 2A described above, it is formed on both sides of the front wall of the substrate 4, and 25 is a support hole for supporting the chamfered tip 21a of the long hinge pin 21 on each side. The rear bracket 2B is formed on both sides of the rear wall of the substrate 4 so as to correspond to the shaft hole 3 of the rear bracket 2B.

Therefore, according to the present embodiment, the moving body 1
6, the long and short hinge pins 20 and 2 on each side supported by the guide member 22 in the cam grooves 19 formed at both end portions of
Obtaining a state in which the followers 20a and 21a of 1 are engaged,
While holding the holding block 6 in the middle part of the moving body 15,
The moving body 15 is connected to the area 5 of the substrate 4 through the two decorative frames 23.
It is mounted so as to be movable inside, and an appropriate cover body 26 is provided on the substrate 4.
With this, the lid L can be assembled very easily.

Therefore, the chamfered tip portions 20b and 21 of the pair of long and short hinge pins 20 and 21 existing on each side are then pressed by pressing the integrated operation buttons 16A and 16B described above.
By inserting b into the corresponding shaft holes 3 of the front and rear brackets 2, the lid L can be rotatably attached to the box body B side as in the conventional case.

When the lid L is closed under such an opening / closing device, as shown in FIG. 3, the moving body 15 integrated with the operation button is compressed in the holding block 6. Since the spring pressure of the coil spring 7 urges the centering position in the area 5 of the substrate 4, the chamfered tip portions 2 of the pair of long and short hinge pins 20 and 21 existing on each side.
0b and 21b are inserted into the shaft holes 3 of the front and rear brackets 2A and 2B through the support holes 24 and 25, and a reliable closed state is guaranteed.

In this closed state, the followers 20a and 21a of the pair of long and short hinge pins 20 and 21 are, as shown in the drawing, at the boundary between the restricting portion 19a and the non-restricting portion 19b of the opposing cam groove 19. On the other hand, while being positioned, the other end 8b of the check lever 8 contacts the upper edge of the front bracket 2A,
Since the one end portion 8a of the moving body 15 is swung downward against the spring pressure of the torsion spring 11, the stopper projection 17 of the moving body 15 has one end portion of the check lever 8 as shown in FIG. It is only located above 8a.

In the closed state of the lid L, in order to open the opening of the box body B, the lid L is temporarily closed.
Operation button 16A on the right side when rotating the
A compression coil spring 7 housed in a holding block 6
When pressed inward against the spring pressure of, as shown in Fig. 5,
The cam groove 19 which is interlocked with the pressing movement of the operation button 16A.
The pair of long and short hinge pins 20 and 21 present on the right side are attached to the front and rear brackets 2 by the action of the restricting portion 19a having a C shape.
It comes off from each shaft hole 3 of A and 2B.

When the right operation button 16A is pushed inward, as shown in the figure, the moving body 15 integrated with the operation button 16A naturally moves in the same direction as the left operation button 16B. Move to. However, each follower 20a of the pair of long and short hinge pins 20 and 21 on the left side
On the contrary, the parts 21a are automatically guided into the parallel non-restricting parts 19b of the opposing cam grooves 19 and do not approach each other, but do not move in the directions away from each other.

Next, when the lid L is rotated slightly upward while the operation button 16A is being pressed, the front bracket 2 of the other end 8b of the check lever 8 is rotated as shown in FIG.
Since the contact state with respect to the upper edge of A is immediately released, the one end 8a of the check lever 8 is rotated upward by the spring pressure of the torsion spring 11 and the stopper projection is formed on its side surface. Engage 17 automatically. As a result, the moving body 15 is locked in place against the spring pressure of the compression coil spring 7 biased to the centering position, and is reliably prevented from returning to the centering position.

Therefore, after that, if the lid L is rotated leftward with the pair of long and short hinge pins 20 and 21 engaged in the shaft holes 3 of the front and rear brackets 2A and 2B on the left side as the rotation axes, As shown in FIG. 7, the opening of the box body B can be opened.

When the lid L in the fully opened state is closed, the lid L is attached to the left and right brackets 2A on the left side.
When a pair of long and short hinge pins 20 and 21 engaged in the shaft hole 3 of 2B is rotated rightward about the rotation axis and the lid L is pressed until it abuts against the opening edge of the box body B,
This time, the other end 8b of the check lever 8 which is exposed to the outside from the window 10 comes into contact with the upper edge of the front bracket 2A,
Since the one end portion 8a of the check lever 8 is swung downward against the spring pressure of the torsion spring 11 and the engagement state of the stopper protrusion 17 with respect to the side surface of the check lever 8 is immediately released, this allows
The moving body 15 returns to the centering position again by the spring pressure of the compression coil spring 7 together with the pair of left and right operation buttons 16A and 16B, and at the same time, in conjunction with this, the pair of long and short hinge pins 20 and 21 on the right side also exist. By the action of the restricting portion 19a of the cam groove 19, the lid L is automatically closed from the respective support holes 24 and 25 into the corresponding shaft holes 3 of the brackets 2A and 2B. .

The closing process of the lid L is shown in FIGS.
Based on the following, in detail, under the present embodiment,
Until the other end 8b of the check lever 8 contacts the upper edge of the front bracket 2A, as shown in FIG. 8A, the reaction force F2 due to the engagement of the stopper protrusion 17 with the vertical surface 12 of the one end 8a of the check lever 8 The moving body 15 is locked in place against the spring pressure F2 of the compression coil spring 7, but the other end 8b abuts the upper edge of the front bracket 2A and the one end 8a is twisted. In the range of starting to swing downward against the reed spring 11, as shown in FIG. 8B, the stopper protrusion 17 only slides on the vertical surface 12 of the one end portion 8a, so that one end portion of the check lever 8 is still kept. The moving body 15 is continuously locked in place by the reaction force F2 received from 8a. In this case, the state of FIG. 8A corresponds to point A of FIG. 9, and the state of FIG. 8B corresponds to point B of FIG. 8A to 8B, the hinge pins 20 and 21 and the shaft hole 3 are
First, the contour edge 3a of the
Corresponds to the state.

When the one end portion 8a is further swung downward, the stopper protrusion 17 is provided with the vertical surface 12 of the one end portion 8a.
Therefore, the moving body 15 also gradually moves in the centering position direction to move the hinge pins 20 and 21 on the opening side of the restricting portion 19a of the cam groove 19 since the moving body 15 gradually moves toward the centering position. It is pushed out in the direction of the shaft hole 3 by action.

At this time also, the reaction force F of the compression coil spring 7
2 is received from the one end portion 8a of the check lever 8, but the check lever 8 receives a downward load of F2 × Tanα in accordance with the inclination angle of the taper surface 13 of itself, and therefore, as shown in FIG. The force of pressing the lid L against the box body B side against the spring pressure of the torsion spring 11 is reduced, and as a result, the operator feels that the lid L is in a fully closed state as if it were approaching. Can be understood, and the operation feeling is improved.

Next, as shown in FIG. 8C, in conjunction with the movement of the movable body 15, the chamfered tip portions 20b and 21b of the hinge pins 20 and 21 pushed in the direction of the shaft hole 3 correspond to the contour edge 3a of the shaft hole 3. 8D, the one end portion 8a of the check lever 8 freely swings downward while separating from the stopper projection 17, as shown in FIG. 8D. It is prevented that the reaction force F2 'is received from the contour edge 3a of the shaft hole 3 to move to the centering position. In the state of FIG. 8D, the lower surface of the stopper protrusion 17 is located at the end of the tapered surface 13, and the chamfered edges of the tip ends 20b and 21b of the hinge pins 20 and 21 come into contact with the edge of the shaft hole 3. The state of FIG. 8C corresponds to point C of FIG. 9, and the state of FIG. 8D corresponds to point D of FIG. or,
FIG. 8C shows the hinge pins 20 and 21 and the contour edge 3 a of the shaft hole 3.
This corresponds to the second state in which and approach each other.

When the lid L is further pressed to the fully closed position,
As shown in FIG. 8E, the chamfered tip portions 20b and 21b of the hinge pins 20 and 21 are aligned with the corresponding shaft holes 3 to release the movement blocking state by the reaction force F2 ′ of the moving body 15.
The moving body 15 is allowed to return to the centering position by the spring pressure of the compression coil spring 7, and at the same time, the hinge pins 20 and 21 on the opening side also receive the action of the restricting portion 19a of the cam groove 19 and thus the moving body 15 shown in FIG. As shown in FIG. 4, the shaft L can be completely engaged in the corresponding shaft hole 3, and thus the closed state of the lid L is guaranteed. The states of FIGS. 8E and 8F correspond to point E of FIG. Therefore, the hinge pin 2 in the present embodiment
As is clear from FIG. 11, 0.21 is different from that of the developed device indicated by the chain line, and the feeding amount changes as indicated by the solid line.

That is, in the present embodiment, in the initial stage in which the one end portion 8a of the check lever 8 swings downward against the spring pressure of the torsion spring 11, similar to the developed device,
The one end 8a of the check lever 8 and the stopper projection 17 are engaged with each other to prevent the moving body 15 from moving. However, when the lid L is fully closed, the one end 8a of the check lever 8 and the stopper projection 17 are separated from each other. Release the engagement, hinge pin 20.2.
By contacting the contour edge 3a of the shaft hole 3 of No. 1, the return of the moving body 15 to the centering position is prevented, and the hinge pin 20.
When the chamfered tip end portions 20b and 21b of 21 coincide with the shaft hole 3, the movable body 15 is configured to be allowed to return to the centering position, so that there is no fear of malfunction.

Further, since the one end 8a of the check lever 8 and the stopper projection 17 are free from the middle of the tapered surface 13, when the force for pushing the lid L in the fully closing direction is weakened, the check lever 8 moves. Even if the one end portion 8a swings upward due to the spring pressure of the torsion spring 11, the upper surface of the one end portion 8a of the check lever 8 and the stopper protrusion 1 as in the developed device.
There is no need to worry about the lower surface of 7.

When the force for pressing the lid L in the fully closed direction is further weakened or made zero, the spring pressure of the torsion spring 11 for urging the check lever 8 causes the lid L to be slightly pushed back in the opening direction. In this case, however, the state shown in FIG. 8C is only achieved, and therefore the movement is not impossible due to being caught.

Further, under the state of FIG. 8C, the lid L is rotated to a position where the hinge pins 20 and 21 on the opening side are separated from the corresponding shaft holes 3, and this time, the operation button 1 on the closing side.
Even if 6B is pressed, the stopper projection 17 engages the one end 8a taper surface 13 of the check lever 8 to prevent the moving body 15 from returning to the centering position. The moving body 15 moves to the centering position, and the hinge pins 20 and 21 on the closing side are never removed from the shaft hole 3. Therefore, the situation in which the lid L is accidentally dropped from the box body B cannot occur.

On the contrary, when the lid L is rotated rightward in order to open the opening of the box body B, although not specifically shown, this time, the left operation button 16B is pressed. Then, the lid L can be opened and closed through the same process as above,
Also, when closing the lid L in the fully opened state,
If the same operation as described above is performed, the lid L can be easily closed, but even at this time, the lid L is attached to the box body B in a state in which there is no fear of malfunction due to the principle described above. Needless to say, it will be blocked.

[0048]

As described above, the present invention obtains the action of the control means for detecting the opening angle of the lid and controlling the hinge pin,
In the vicinity of the lid being fully closed, once the hinge pin is brought into contact with the contour edge of the corresponding recessed hole portion, and when the hinge pin is aligned with the recessed hole portion, the hinge pin is engaged with the recessed portion by its biasing means. Since it is characterized by making it possible, there is no concern that a malfunction will occur, and the lid can be accidentally dropped from the box body. Further, in particular, under claims 2 and 4, in addition to the above advantages, the operation feeling is improved, and under claim 3, elastic deformation of the check lever is reduced, and the left and right sides of the tapered surface are reduced. Since the positional accuracy in the direction is improved, there is an advantage that the movement of the hinge pin is maintained with high accuracy and the occurrence of the malfunction is more surely prevented.
