[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-way opening / closing mechanism for a lid, which is suitably used as a mechanism for opening and closing a lid of a center console box of an automobile.

[0002]

2. Description of the Related Art Conventionally, as a center console box of an automobile, a cover has been provided so as to be easily opened and closed not only from a driver's seat side but also from a passenger seat side or a rear seat side. A configuration in which the lid can be opened and closed from a direction is known, and as such a console box, a console box disclosed in Japanese Utility Model Laid-Open Publication No. 2-33755 can be exemplified.

As shown in FIGS. 11 and 12, a console box disclosed in Japanese Utility Model Laid-Open Publication No. 2-33755 is provided at opposite ends of a lid b for closing an opening of a console box a. Operation buttons c, c
Is provided, and by operating the operation buttons c, c,
The lid b can be opened and closed from both sides.

That is, as shown in FIG. 12, the operation buttons c, c are connected to cam bodies d, d movably disposed inside the lid b, and the operation buttons c, c , C
, These cam bodies d, d move against the urging force of the spring e. Further, a pair of support shafts f, f are provided along inner edges of both ends of the lid body b facing each other, and these support shafts f are cams protruding from the base end. The projection i is the cam body d,
d are slidably inserted in cam grooves j, j provided in d, and are connected to the cam bodies d, d, and the leading ends are loosely fitted in bearing holes g provided in the console box a. .

Then, one of the operation buttons c and c is pressed to move one cam body d against the urging force of the spring e, and one cam body d is moved by the cam action of the cam groove j and the cam projection i. , The tip of the support shaft f is moved out of the bearing hole g, and the locked state of one end of the lid b is released. Then, while maintaining this state, one end of the lid b is lifted and the lid b is pivoted about the support shafts f, f at the other end.
Is rotated to open the lid b to open the opening of the console box a. When the cover b is closed from this state, the cover b is closed and pressed, so that the tip of the support shaft g is connected to the console box a.
Is guided into a tapered recess h (see FIG. 11) provided at the periphery of the opening, and fitted into the bearing holes g, g, and locked in the initial closed state. In this case, in this console box, even if any of the operation buttons c and c is operated,
By the same operation as described above, the lid b can be opened and closed, and the lid b can be opened and closed from two directions.

However, this console box a
When opening the lid b, the two-way opening / closing mechanism used for the lid b presses one of the operation buttons c and c to open the lid b.
Is released, and in a state where this state is maintained, that is, in a state where the operation button c is pressed,
The lid b must be rotated, and the operability at the time of the opening operation is not always good. Further, since the mechanism for operating the support shafts f, f on one end side and the mechanism for operating the support shafts f, f on the other end side are completely independent mechanisms, one of the operation buttons c is pressed. If the other operation button is pressed while rotating the lid, the support shafts f, f on both sides are simultaneously disengaged from the bearing holes g, g of the console box a, and the lid b is moved to the console. There is a drawback that it comes off the box a.

As another mechanism for opening and closing the lid from two directions, for example, there is a method using a link mechanism shown in FIG. That is, one end of the pair of arms k, k is rotatably connected to the console box a, and the other end of the arms k, k is rotatably connected to the lid b.
Is attached to the console box a, and the lid b is opened and closed from one direction, the lid a is rotated between the lid b and the arms k, k without rotating the arms k, k. (Figure 1

The arm k, k is pivoted between the arm k, k and the console box a without rotating the lid b between the arm k, k and the arm k, k. Rotate
The cover b is opened and closed.

However, in the two-way opening / closing mechanism using this link mechanism, as shown in FIG. 13, the arms k, k constituting the link mechanism are exposed to the outside, and the appearance is poor. It also has two rotation axes between the arms k, k and the console box a and between the arms k, k and the lid b, and when the lid b is opened and closed, both the rotation axes rotate. Since it is possible, when opening and closing from any direction, the lid b must be operated so that the lid b is rotated only by the other rotation axis without rotating by one rotation axis. In addition, the turning operation of the lid b tends to be unstable, and the operability at the time of opening and closing is poor. Further, when such a link mechanism is used, it is extremely difficult to provide a lock mechanism for locking the lid b at both ends of the lid b.

The present invention has been made in view of the above circumstances, and enables the lid to be reliably opened and closed without the lid coming off, and has excellent operability at the time of opening and closing.
