[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door angle regulation device having a hinge mechanism capable of regulating a door at an arbitrary angle by interlocking with a door handle.

[0002]

[Prior art]

 Conventional automobile rear doors are equipped with a hinge mechanism that enables opening and closing, but most of them do not have a mechanism for restricting the rotation of the door.

In some of the above conventional door hinge mechanisms, a stopper such as a hook or a bracket is additionally provided at a position of 90 degrees from the rear to regulate the rotation.

[0004]

[Problems to be solved by the device]

 The above-mentioned conventional door hinge mechanism is essentially free from 360 degrees, and a large door with a large area is susceptible to wind pressure and moves abruptly, so there is a problem that attention must be paid during loading and unloading work. .

The conventional mechanism that regulates at a constant angle has a problem that the working range is limited because the angle is fixed, and in order to solve it, it is necessary to adjust the attachment of the hook or the bracket stopper each time. However, there was a problem that it was troublesome, and the cost was high because the shape of these stoppers was different depending on the vehicle model.

Therefore, the inventors of the present invention regulate the door at an arbitrary angle by changing the engagement relationship between the prismatic member formed in a part of the hinge mechanism and the engaging portion by a simple operation with the door handle. As a result of further research and development focusing on the technical idea of the hinge mechanism of the present invention, it is not necessary to pay attention to the movement of the door due to wind and others during the work, and the work and the angle according to the need can be realized by a simple operation. We have arrived at the present invention that achieves the purpose.
