Description

  The present invention relates to a hinge device for a vehicle console box including a lid (lid) that can be opened and closed.

  In general, a console box as an accessory case is integrally provided between a driver's seat and a passenger seat on an automobile floor console so that various drive accessories or compact discs can be accommodated. ing. The lid (cover) that covers the upper opening of the console box so as to be freely opened and closed may be formed as a so-called slide type or shade type, but is formed as a lid that also serves as an armrest, and the rear end is a box. It is common to couple | bond with a main body with a hinge apparatus (hinge) (for example, refer patent documents 1-3).

The vehicle console box has a box-like console box body (base body) and a lid for opening and closing the opening of the console box body. One of the console box body and the lid has a rotation shaft of a hinge device (hinge), and the other has a rotation bearing of the hinge device (hinge) that pivotally supports the rotation shaft. For this reason, the lid rotates between an open position for opening the opening and a closed position for closing the opening.
However, even in this case, if the rotation bearing is not molded with high accuracy, the elastic body will be caught by the rotation bearing or the rotation shaft, so that the rotation load will increase and the rotation operability will not be improved sufficiently. Or, it may be difficult to assemble the elastic body (biasing member) to the rotary bearing. For this reason, a rotating device (console box) that is excellent in assembling property of the elastic body and rotating operability is desired. For example, a resin material having a small friction coefficient between the rotating shaft and the rotating bearing. There is disclosed a rotating device (console box) in which a sliding body made of is interposed to improve the rotating operability (see, for example, Patent Document 4).
