Description

[Detailed description of the invention] - Industrial application field - The invention consists of an inverted concave elongated installation member (mounting plate with a channel shape) that is fixed to the door mounting frame, and a mounting plate that is fitted into the recess of the door and fixed. In a hinge in which a container-shaped mounting member (cup-shaped socket) with an open upper surface is relatively rotatably and relatively bendably connected via a pair of links, the hinge is in a closed state. It relates to a device equipped with a catch mechanism for holding.

〓Prior art〓 In general, a hinge in which a mounting member called a mounting plate and a mounting member called a socket are connected via two links has the following features: the opening angle can be increased; It is more desirable than other hinges in that it is possible to freely select the manner in which the door is attached to the door mounting frame, such as attached or externally attached, and it is also possible to incorporate a catch mechanism to keep the door closed.

Incidentally, in conventional hinges of this type, a coil spring is attached to the shaft pin on the installation member side to provide a force for maintaining the closed state of the door.

〓Problem to be solved by the invention〓 In the case of the above-mentioned conventional technology, the door closing force can be applied via a coil spring, but since the force of the spring is constant, it is difficult to When the opening/closing speed of the door, the impact when closing the door, etc. differ depending on the individual usage conditions, it is impossible to adapt to these.

In this case, the coil spring can be replaced, but it is troublesome to disassemble the hinge to replace the spring, and it is unreasonable to disassemble the spring once assembled.

Therefore, it is necessary to prepare hinges with different catching forces, that is, a wide variety of hinges, and select a hinge with an appropriate catching force depending on the various door installation methods. This is undesirable in that sense, and it also increases costs.

Moreover, even if you select a hinge with an appropriate catching force and attach the door to the door mounting frame, it is unlikely that the optimum catching force will be obtained, and even if the catching force is optimal, it will not be possible to use the hinge for a long time. As the spring force decreases over time, it is difficult to maintain good catching force.

In view of the above-mentioned technical problems, the present invention aims to provide a hinge equipped with a catch mechanism that can obtain an appropriate catch force through simple adjustment operations without replacing the spring and related parts.

A counterclockwise force is applied using the shaft pin 7 as a fulcrum.

That is, in the state shown in FIG. 2, the counterclockwise force acting on the outer link 5 acts as a catching force to close the door 3, so the door 3 is held in the closed state and is opened involuntarily. Never.

When opening the door 3 from the closed state, it is sufficient to resist the force of the spring 16 and apply enough force to the door 3 to cause the engagement rod 5d to come off the top surface 12b. Each part operates in the opposite manner to the above, and the door 3 is opened.

Furthermore, regarding the catch mechanism 11, the spring 1
Since the catching force is determined by the elastic force of the spring 16, it is only necessary to adjust the load of the spring 16 by operating the adjustment screw 14. Thus, it is necessary to adjust the load of the spring 16 by operating the adjustment screw 14. You can obtain the catching force corresponding to the

= Effect of the invention = As explained above, the present invention can obtain the catching force when closing the door through the catch mechanism provided on the hinge, and moreover, the catching force can be adjusted arbitrarily by simple operation using the adjustment screw. Since it is adjustable, it is possible to use a type of hinge to ensure a catch function that corresponds to the size, weight, opening/closing speed of the door, impact when closing the door, etc.

Therefore, the unreasonableness of having to replace the spring and its related parts, and the unreasonableness and uneconomical production of having to stock hinges of other types are eliminated.
