In addition, it is provided on the free end side of the pivoting part of the rotating plate 2 and the fixed part 1, and at a position that does not overlap when a lid or door is inserted between the rotating plate 2 and the holding plate 6. The insertion hole 10 is a screw hole provided in the presser plate 6 so as to overlap the insertion hole 9, and the tip of a small screw 11 inserted into the insertion hole 9 is screwed into this hole.
Reference numeral 12 denotes a rubber plate fixed to the surface of the holding plate 6 facing the rotating plate 2 for protecting the held object.

Reference numeral 13 denotes a box-shaped spring receiver with an open lower surface and one side, which is slidably arranged in a box-shaped fixing part 1, and a pair of mounting plates 1 provided at the upper end thereof.
4 and 14 are pivotally attached to the connecting plates 3 and 3 with pins 15. The pin 15 may be a single shaft as long as it pivotally connects the connecting plate 3 and the mounting plate 14, or it may be a pin that connects only this connecting portion.
16 is a compression spring interposed between the bottom plate of the fixed part 1 and the upper plate of the spring receiver 13;
is biased toward axis 5. That is, pin 15
is positioned closer to the small screw 11 than the shaft 5, so that the spring force of the compression spring 16 acts on the rotating plate 2 to open it. 17 is the fixed part 1
A friction plate made of fiber, synthetic resin, etc. is attached to the inner surface of the opposing wall or the outer surface of the spring receiver 13 and is interposed between the fixed part 1 and the spring receiver 13. This is to prevent sudden rotation.

This hinge is used in audio racks that do not want the box body to vibrate when the lid or door is opened or closed, and when the lid or door is opened, the compression spring 16
The compression spring 1 makes it easier to open the lid or door by assisting the spring force in the opening direction, and conversely, when closing the lid or door, the compression spring 1 prevents the lid or door from rapidly moving by its own force.
6 and a friction plate 17 interposed between the fixed part 1 and the spring receiver 13.

When this hinge is used, the fixed part 1 is fixed to a box or the like. The end of the lid or door is inserted between the rotating plate 2 and the holding plate 6, and the machine screw 11 is tightened. Then, the holding plate 6 has its support plate 7 connected to the shaft 5 through its elongated hole 8.
Since the machine screw 11 is screwed into the screw hole 10 of the holding plate 6, the holding plate 6 rotates the lid or door as the machine screw 11 rotates. It is clamped and fixed between the plate 2 and the plate 2. Furthermore, as described above, the support plate 7 is attached to the shaft 5 through the elongated hole 8 extending substantially perpendicularly to the presser plate 6 in the same direction as the direction in which the rotating plate 2 and the presser plate 6 face each other. The plate 6 moves with its entirety parallel to the rotating plate 2, and the rotating plate 2 and the holding plate 6 press with almost the entire contact area with the object to be held, and the entire object is held with uniform pressure. be done. Therefore, the lid or door made of glass or any other material can be stably placed between the rotating plate 2 and the holding plate 6.
In addition, it can be installed reliably, and the presser plate 6 can be pressed parallel to the rotating plate 2 against several types of lids or doors with different thicknesses. can also be installed securely.

The support plate 7 of the holding plate 6 is attached to the shaft 5,
In addition, since it is attached to the rotating plate 2 with machine screws 11, the holding plate 6 does not move unnecessarily, and the end of the lid or door can be easily inserted between it and the rotating plate 2. Since the lid or door is held between the rotating plate 2 and the holding plate 6, there is no need to drill a mounting hole in the lid or door, and the glass lid or door can be mounted efficiently and easily.

Further, the compression spring 16 is housed in the fixing part 1 having a concave planar cross section and having a bottom plate, and supports a spring receiver 13 at its upper end. Since the compression spring 16 and the spring receiver 1 are pivotally connected to the connecting plate 3 of the
