Description

[Detailed description of the invention] The present invention relates to a hinge applied to the installation of a door.

Generally, a separate locking device is used to hold the door in the closed position, but if the hinge itself to which the door is attached has a stopper function, the door can be closed without using the locking device. It is convenient to be able to maintain the

Therefore, there have been known hinges that have a stopper function, for example, by connecting a mounting plate that is fixed to a door mounting frame and a cup-shaped member that is embedded and fixed to the door with a plurality of arms and links. It is being

However, this is provided on one side of the concave portion of the cup-shaped member and is elastically biased by an engaging element χ spring. The door is configured to be held in a closed state by pushing the interlocking elements and then locking them together.

However, according to the above-mentioned hinge, the stopper function is only for holding the door closed, and it is not capable of holding the door open. Also, the stopper mechanism has a stopper function, for example, when the cup-shaped member is made of plastic, the thin side wall Since the locking element was pivoted through a notch, problems with strength were unavoidable.

Therefore, as a result of studies in view of the above-mentioned circumstances, the present invention provides a hinge equipped with a stopper function that can hold the door in both the opening and closing positions. The bent end of the rotating arm is provided so that it rotates in the direction of opening the door and the direction of closing the door, respectively, from mid-rotation, and by an elastic mechanism that elastically biases the bent end in the direction of rotation,
Holds the door open while opening and closing the door,
The purpose of the present invention is to achieve the function of keeping the door closed.

Below, detailed description will be made based on the drawings showing specific examples of the present invention.
In Figures 1 to 3, a mounting plate 2 fixed to a door mounting frame 1 and a cup-shaped member 4 embedded and fixed in a door 3 are connected by two arms 5 and 6 so that they can be opened and closed mutually. The two arms 5 and 6 protrude to the front of the mounting plate 2. The mounting plate 2 and the cup-shaped member 4 are pivotally connected to the front end 2a and one side wall 4a of the cup-shaped member 4 facing the front end by fulcrum pins 7, 8, 9, and 10, respectively.
When the door is closed, the front end 2a of the mounting plate 2 and both arms 5, 6 are housed in the four parts 4b of the cup-shaped member 4, as shown in FIG.

One of the arms 5, which is located at the front end 2a of the mounting plate 2 and is pivotally attached to the most extreme end thereof, is bent as shown in the figure, and the bent part 5a is connected to the most extreme end of the mounting plate 2. The bent end 5b is pivotally connected to the tip by the fulcrum pin 7 and protrudes toward the mountain ink plate 2 side.
is designed to reciprocate from the middle of the rotation accompanying the opening/closing operation, and the bent end 5b is provided with elasticity in the rotation direction by an elastic mechanism 11 interposed between it and the mounting plate 2. It is configured to apply repellent force and perform the functions of holding the door open and holding the door closed.

That is, the resilient rock structure 11 has one end pivotally connected to the bent end 5b by a pin 12, and the other end slidably inserted into a hole 13 formed through the front end 2a of the mounting plate 2. A compression spring 15 is mounted on the sliding rod 14, and one end of the spring 15 is attached to the sliding rod 14.
The other end is supported by the stepped portion 14a of the mounting plate 2, and the other end is supported by the bottom wall of the recess 16 of the mounting plate 2, and the arm 5 is rotated counterclockwise with respect to the bent end 5b of the arm 5 with the fulcrum pin 7 as the rotation axis in FIG. The repulsive force is applied to the

Similarly, as is known, the mounting plate 2 can be adjusted in the front and back, left and right, and up and down directions by interposing adjustment plates (not shown) on a fixed plate 2b screwed to the door mounting frame 1. On the other hand, the cup-shaped member 4 is also fixed by screws or the like after being fitted into a recess 3aK previously provided in the door 3, as is conventional.

In the above configuration, the arm 5 has its bent end 5b.
is elastically biased by the elastic mechanism 11 and is pressed and rotated counterclockwise about the fulcrum pin 7 in FIG. The door 3 is rotated in the direction of closing the door together with the door 3, and the door 3 is closed, and the door 3 is kept in the correct position by the closed door position detector shown in FIG. 1, so that it will not open involuntarily.

When the door 3 is rotated in the opening direction from the above-mentioned closed door position, the arm 5 is rotated clockwise around the fulcrum pin 7 and the door 3 is opened. The resiliently biased resilient mechanism 11 is compressed and rotated as shown in FIG. 2.

When the door 3 is further rotated in the opening direction, in the middle of the rotation,
The arm 5 is reversed counterclockwise from the position shown in FIG. 2, and the opening angle of the door 3 becomes larger.

At this time, the bent end 5b of Arno.
1, so even if the door opening operation is stopped at this point, the elastic force of the resilient mechanism 110 acts as an opening door lock, and the door 3 is opened to the opening end as shown in FIG. , it will be stopped and held in that position and will not close involuntarily.

Furthermore, after the bent end 5b rotates one clockwise direction from the position shown in FIG. Since the elastic force acts on the bent end 5b as a closing lever, the door is automatically closed and is held at the closed door position.

As explained above, according to the hinge according to the present invention, the mounting plate 2 fixed to the door mounting frame 1 and the cup-shaped member 4 fixing the door 3 have a plurality of arms 5, 6.
At least one arm 5 is bent, and is pivoted by a fulcrum pin 7 between the front end 2a of the mounting plate and the bent portion 5a so that the bent end can freely reciprocate during opening and closing operations. A sliding rod 14 that is reciprocatably fitted into a hole 13 provided in the front end 2a of the mounting plate V-2 is pivotally attached to the bent end 5b, and the sliding rod 14 and the hole 13 The compression spring 15vc interposed between the bent end 5b and the inner periphery applies an elastic force to the bent end 5b to switch between the door opening direction and the closing door direction. It is possible to hold each door in the closed door position, and the holding in both positions is achieved by the elastic force of the compression spring 15 acting smoothly through the sliding rod 14 at the bent end 5bK of the arm. After the bent end 5b of the arm 5 is reversed during the door opening or closing operation, it acts as an opening force or a closing force, so that the door opening and closing operations can be smoothly and easily brought to the stop position, respectively. Moreover, the door can be held open and the door closed statically.

In addition, since the sliding rod 14 and the compression spring 15 can be installed using the space of the front end 2a of the mounting plate 2, they can be installed in the same size as this type of hinge that does not have a stop function. In addition, since the sliding rod 14 is pivotally connected to the bent end 5b of the arm, not only will both 14 and 15b not come off inadvertently,
From now on, there will be no more unreasonable rubbing between the sliding rod 14 and the bent end 5b, and there will be no risk of unpleasant noises or wear and tear on parts.
