行うことができる。According to the present invention, when the lid member is opened and closed between the folded state in which the lid portion is superposed on the main body portion and the expanded state in which the lid portion is opened by 180 degrees, the lid member is provided by the biasing means provided in the vicinity of the hinge portion. When the part is in the folded state, it is elastically biased in the closing direction, so that the lid part is stably held in the folded state. Further, when the lid portion is in the deployed state, the biasing means elastically biases it in the opening direction, and the stopper means restricts the opening beyond the deployed state, so that the deployed state is stably held. .. Therefore, when opening the lid, it opens against the urging force, but the urging force gradually weakens and the urging force in the opening direction accelerates in the opening direction from the approximately intermediate position of opening and closing. Will reach the state. Similarly, when the lid part is closed, it is heavy at first and reaches a folded state so that it is accelerated in the closing direction from a substantially intermediate position. Since the opening / closing position of the lid body is held by the biasing means as described above, an engaging member or the like for locking at a predetermined position is not required, and an operation such as unlocking for opening / closing operation is performed. Is unnecessary and the opening / closing operation can be performed simply and smoothly.

作は加速される。Embodiments of the present invention will be described below with reference to the accompanying drawings to provide an understanding of the present invention. still,
The following examples are examples of embodying the present invention and do not limit the technical scope of the present invention. Figure 1
FIG. 4A is a side view showing a folding opening / closing structure of an electronic device according to an embodiment of the present invention in the order of opening / closing operations thereof. In FIG. 1, (a) shows a state in which the lid part 1 covers the upper surface of the main body part 3 in a folded state and is not in use, and (b) shows a state at a substantially intermediate position of the opening / closing operation. FIG. 3C shows the lid 1
Is opened 180 degrees and is expanded to the same horizontal position as the main body 3. In FIG. 1, an electronic device 10 has an operation unit, a display unit, and the like arranged on a main body 3 and a lid 1.
It is configured so that the form can be changed between when used and when not used. The lid 1 is openably and closably connected to the main body 3 by the hinge portion 2, and the hinge portion 2 position of the lid portion 1 has a circular arc sliding surface having a radius centered on the rotation axis 2a. The moving arm 4 is provided integrally with the lid portion 1. On the other hand, one end of the main body 3 is supported by the main body 3, and the other end of the main body 3 is provided with a spring member 5 which elastically contacts the circular arc sliding surface of the rotary arm 4 to bias the rotary arm 4 in a predetermined direction. It is provided. The spring member 5 and the rotating arm 4 constitute a biasing means for opening and closing the lid 1. Rotating arm 4 by spring member 5
The elastic contact point for urging depends on the opening / closing position of the lid body 1 as shown in FIGS. 3 (a), (b) and (c), and the urging force and the urging direction depend on the opening / closing position of the lid body 1. It is configured to change. The main body portion 3 is formed by the lid portion 1 shown in FIG.
In the folded state in which is closed, since the rotating arm 4 is in contact with the end of the spring member 5 at one end of the circular arc sliding surface,
The torque arm that urges the lid portion 1 in the closing direction is large, and the lid portion 1 is pressed against the main body portion 3 to reliably hold the folded state. When the lid 1 is opened from this state against the urging force, the opening is heavy at first but the torque arm gradually becomes smaller, and the urging force is increased from about the middle position of the opening and closing shown in FIG. And the opening operation is accelerated to the deployed state shown in FIG. 1 (c). In the unfolded state, the rotating arm 4 receives the urging pressure from the spring member 5 on the other end of the circular arc sliding surface and further urges it to move in the opening direction. The stopper means configured to come into contact with the locking step portion 1a formed in the vicinity of the hinge portion 2 of the body portion 1 stops the operation of the lid body portion 1 in the opening direction more than the deployed state, and maintains the deployed state. To be done. When the lid 1 is rotated in the closing direction from the expanded state shown in FIG. 1C, the closing operation is against the bias in the opening direction like the opening operation, so the closing operation is heavy, but The torque arm becomes zero at a substantially intermediate position between opening and closing, and then the biasing force changes in the closing direction, so that the closing operation is accelerated to the folded state of FIG. 1A.

きる折り畳み開閉構造を提供することができる。As described above, according to the present invention, when opening and closing between the folded state in which the lid portion is superposed on the main body portion and the deployed state in which the lid portion is opened 180 degrees, the biasing force provided in the vicinity of the hinge portion is provided. When the lid body portion is in the folded state by the means, it is elastically biased in the closing direction, so that the lid body portion is stably held in the folded state. Also, when the lid body is in the deployed state, the biasing means elastically biases the lid in the opening direction,
Since the stopper means restricts opening beyond the deployed state, the deployed state is stably held. Therefore, when opening the lid, it opens against the urging force, but the urging force gradually weakens and the urging force in the opening direction accelerates in the opening direction from the approximately intermediate position of opening and closing. Will reach the state. Similarly, when the lid part is closed, it is heavy at first and reaches a folded state so that it is accelerated in the closing direction from a substantially intermediate position. Since the opening / closing position of the lid is maintained by providing the biasing means and the stopper means as described above, an engaging member or the like for locking the lid at a predetermined position is not required and an opening / closing operation is performed. It is possible to provide a folding opening / closing structure that does not require operations such as unlocking and can simply and smoothly perform opening / closing operations.
