Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hinge device for pivotally connecting the base of a lid to a mounting portion, and is used, for example, in a side-opening rear door of an automobile. Regarding.

``Prior art'' Conventionally, in the side-swing rear door of an automobile, the hinge shaft of the hinge device is fixed, so if the hinge shaft is made to protrude greatly, the door can be opened at a large angle, but it is possible to open the door at a large angle. Since the rear door protrudes, the opening angle of the rear door is naturally limited to around 240 degrees at best.

In addition, some have movable hinge shafts that allow the door to open 270 degrees, and others have quite complex structures with many components.

``Problem to be solved by the invention'' However, with such conventional technology, if the former occurs, the hinge shaft tends to protrude from the door or lid body, which is not only a nuisance and danger, but also an unsightly one. Bad,
Moreover, there was a problem that the opening angle was not sufficient.

In addition, if the latter is the case, not only will the structure be complicated and the cost will increase, but if it is a complicated structure, there will be many parts that break down, and there may be problems with durability and maintainability. Ta.

The present invention has been made in view of these conventional problems, and an object of the present invention is to provide a hinge device that has a simple structure, does not have any protruding parts when the door is closed, and operates smoothly and reliably.

"Means for Solving the Problems" The gist of the present invention for achieving the above object is as follows: In a hinge device that is pivotally attached to an additional edition section at the base of a lid body, a first hinge member that is fixed to a mounting section is provided. a second hinge member fixed to the lid, and an intermediate hinge member having a first pivot shaft at one end pivoted to the first hinge member and a second pivot shaft at the other end pivoted to the second hinge member. In the operating range until the lid opens approximately 90 degrees, the first hinge member or the second hinge member and the intermediate hinge member of either the first pivot shaft or the second pivot shaft rotate. The present invention is characterized by the provision of a control member that allows rotation of the pivot shaft that suppresses rotation on one side while allowing rotation of the other side, and in an operating range in which the lid body is opened approximately 90 degrees or more. It resides in the hinge device.

"Operation" In the operating range until the lid opens approximately 90 degrees, the rotation of the first hinge member or the second hinge member and the intermediate hinge member on either the first pivot or the second pivot is controlled by the control member. Only the other of the first pivot or the second pivot is rotatable, and when the lid is opened or closed, the lid rotates about the pivot.

When the lid body reaches a range of movement in which it opens beyond approximately 90 degrees, the control member, contrary to the above, rotates the first or second axis, which was allowed within the rotation range of 90 degrees, in response to the movement. On the one hand, the rotation is suppressed, and on the other hand, the one whose rotation was suppressed becomes able to rotate.

In the operating range where the lid opens more than approximately 90 degrees, the pivots are switched from those within 90 degrees, and the lid rotates around the one pivot, and the position of the pivot is adjusted appropriately depending on the degree of opening of the lid. By switching to , the lid can be opened up to 270 degrees.
