DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention is a hinge device for pivotally attaching a base part of a lid to a mounting part, and is used for a rear door of a car door that opens laterally, for example. Regarding

"Prior Art" Conventionally, there is a demand for a side-door type rear door of an automobile to be rotated 270 degrees until the door whose rear surface is closed extends along the side surface of the vehicle body.

A conventional technique that enables this is, for example, that shown in FIG.

That is, the vehicle body-side hinge member 1 and the door-side hinge member 2 are pivotally attached to each other by the hinge shaft 3, and the shaft 3 is arranged so as to project considerably from the vehicle body, so that the door can be opened by 270 degrees.

[Problems to be Solved by the Invention] However, in such a conventional technique, there is a problem that not only the hinge shaft 3 largely projects from the door and the vehicle body to occupy a space but also safety is not preferable.

The present invention has been made in view of such conventional problems, and an object thereof is to provide a hinge device which is simple in structure, has no protruding portion when the door is closed, and operates smoothly and reliably.

[Means for Solving the Problem] The gist of the present invention for achieving the above object is to provide a hinge device for pivotally attaching a base portion of a lid to a mounting portion, and a first hinge member fixed to the mounting portion. A second hinge member fixed to the lid, and a first hinge at one end of the first hinge member.
An intermediate hinge member pivotally attached via a pivot and pivotally attached to the second hinge member via a second pivot at the other end, at an end of the first hinge member pivotally attached to the intermediate hinge member. A second cam portion is formed at an end portion of the second hinge member pivotally attached to the intermediate hinge member, and a control member is attached to the intermediate hinge member, and one end of the control member is formed. Is provided with a first follower portion that engages with the first cam portion, and a second follower portion that engages with the second cam portion is provided at the other end, and in the operating range until the lid opens approximately 90 degrees, Either the first cam portion or the second cam portion, the first follower portion or the second follower portion is provided so as to suppress rotation of the first hinge member or the second hinge member and the intermediate hinge member. With the restriction part to be locked , A stopper is provided to prevent bending at about 90 degrees or less at the relevant part, and the stopper is engaged with the first follower part or the second follower part on the side where the restriction part is not provided, and the lid body opens approximately 90 degrees or more. In a hinge device, a release operation unit that displaces the control member to release the inhibition of the rotation in a certain operation range is provided on either one of the first cam unit or the second cam unit. Exist.

[Operation] In the operation range until the lid body opens approximately 90 degrees, the limiting portion of the first cam portion or the second cam portion locks the first follower portion or the second follower portion to suppress rotation. And the lid can be opened about either the first axis or the second axis.

When the lid is in the operation range of opening beyond about 90 degrees, the releasing operation part displaces the control member to separate from the partner to which the restricting part is locked, and the rotation is no longer restrained. It is possible to pivot about either the pivot or the second pivot, and when the lid is fully opened, the door can be opened up to 270 degrees, and the release operation unit separates from its counterpart.

When the lid is closed, it is pivoted on either the first pivot or the second pivot from the fully opened position to the opening angle of 90 degrees and closed.

When the releasing operation portion of the first cam portion or the second cam portion comes into engagement with the first follower portion or the second follower portion when closing, a moderation resistance is generated, and the portion having the restriction portion prior to that portion is provided. Rotate about either the first axis or the second axis until it hits the stopper until the opening is 90 degrees.

When the lid body is further closed, the lid body rotates about either the first pivot axis or the second pivot axis of the portion provided with the releasing operation portion. When the lid is fully closed, one of the first follower portion and the second follower portion is moved by the release operation portion, the control member is displaced, and one of the first cam portion or the second cam portion with which the limiting portion is a partner is moved. Is locked, and rotation in the relevant part is blocked.
