Description

Detailed Description of the Invention (Industrial Application Field) The present invention provides a hinge that is removably attached via a mounting plate that is fixed along the inner surface of the side plate of the frame in order to pivotally connect the frame and the door. More specifically, a hinge arm having a tightening screw and a joint adjustment screw for adjusting the mounting position of the door is held on the mounting plate by an elastic snap-fit mechanism via an intermediate member. , regarding the so-called hidden hinge.

PRIOR ART In conventional hinges, the hinge arm is secured to the mounting plate by a clamp screw, which generally projects through an angled hole to allow adjustment of the hinge arm in the depth direction of the frame.

Recently, snap-fit connections have become known for securing hinge arms to mounting plates. For example, DE
-A-30 26 796 and DE-A-30 39 328 show a hinge with a hinge arm and an anchor plate, in which the two parts to be connected include inserting the hinge arm into the guiding part of the anchor plate; and snapping together by longitudinally moving said hinge arms. A similar method of fixing a hinge arm to a mounting plate is shown in DE-A-24 60 127. In the hinge shown in DE-A-32 41 284, the hinge arm is inserted into a lateral guide part of the mounting plate and is clamped to the mounting plate using eccentric means.

The above-described method of fixing the hinge arm to the mounting plate has the advantage that the hinge arm can be fixed quickly to the mounting plate during the assembly operation and, moreover, no tools are required for the mounting.

(Problems to be Solved by the Invention) However, this advantage is difficult to install because the door must be held separately when the hinge arm is attached to the mounting plate. for example,
If the door is held with one hand and the hinge arm is installed with the other hand, another person is required, especially with a screwdriver, when fixing the hinge arm with the tightening screw.

Furthermore, when the hinge arm or the intermediate member is inserted into the mounting plate from the front of the frame, a disadvantage arises in that the hinge is easily tilted. This tendency is particularly noticeable when installing long, heavy doors with a large number of hinges lined up in the height direction. In most cases, the hinge arm must fit over almost the entire length of the mounting plate.

An object of the present invention is to enable fine adjustment of the mounting position of the hinge arm after it has been temporarily fixed when mounting the hinge arm on a mounting plate without requiring the hands of another person, and to provide a simple structure for the hinge arm.
