CONSTITUTION: The hinge with a limited angle range is composed of: a projected guide groove(12) making a hinge stopped at a limited angle; a hinge wing(20) provided with a catching projection(22) corresponding to the guide groove; a hinge pin(30) necessary to join matched hinges together. The catching projection rotates along the guide groove and then stops at a limited projection. Therefore the hinge halts without an additional stopper. Also the angle varies as required and the hinge is be divided into several sections, so that a user is able to choose a proper hinge size according to the one of an object to be put on. |
