DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge device having a function of stationaryly fixing a door in a closed state and an open state.

[0002]

2. Description of the Related Art It is desirable that a door used for an entrance or the like can be stationaryly fixed in a closed state and an open state in view of its operability.

However, since the conventional fixing device is large and heavy, there are some restrictions on its installation. If it cannot be installed, a method of fixing it to a floor or the like with a hook or the like is adopted, and the operability is significantly reduced. Was.

[0004]

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a hinge device with a fixing function which is small and light and which can securely fix a door stationary in a closed state and an open state.

[0005]

The hinge device with a fixing function according to the present invention will now be described with reference to the accompanying drawings, in which the main body 1 is fixed to the fixed frame 10 or the door 9 and the rotary shaft 2 is fixed. It is rotatably fitted into the main body 1. At the middle part of the rotating shaft 2, two fixing planes 7, 8 forming an angle of 90 ° with each other are provided.
The door 9 or the fixed frame 11 is fixed to 3.

[0006] A push rod 5 whose flat end surface 5 a selectively comes into contact with the fixing flat surfaces 7, 8 is arranged perpendicularly to the rotary shaft 2, inserted into the main body 1, and attached axially by a disc spring 6. Energize. The adjusting screw 3 provided with the engaging portion 4 of the rotating operation tool on the head 11 is screwed into the main body 1, and the push rod 5 is pressed toward the rotating shaft 2 via the disc spring 6.

[0007]

The door 9 is fixed to the fixed frame 11 as shown in FIG.
Is closed, the flat end surface 5a of the push rod 5 comes into contact with one of the fixing flat surfaces 7 of the rotary shaft 2 as shown in FIG. 4, and the door 9 is stably fixed in the closed state.

When the door 9 is opened and rotated with respect to the fixed frame 11, the rotary shaft 2 is rotated integrally with the door 9, and the push rod 5 that has been in contact with the fixing plane 7 is pushed back. When the door 9 is further rotated, the push rod 5 comes into contact with the other fixing plane 8, and the door 9 is fixedly held in an open state.

[0009]

In the embodiment shown in the drawings, the main body 1 is fixed to the fixed frame body 10 with screws 14, and the rotating shaft 2 is rotatably fitted into the shaft hole 15 of the main body 1. A difference is provided between the two fixing planes 7 and 8 of the rotating shaft 2 from the center of the shaft. The fixing plane 7 is large and the fixing plane 8 is smaller. Therefore, while the stationary state can be reliably fixed in the closed state, the closing operation from the open state can be smoothly performed.

Both ends 12 and 13 of the rotating shaft 2 are at an angle to the fixing plane 7, and the rotating shaft 2 is fixed to the door 9 via the both ends 12 and 13. for that reason,
When the door 9 is in the closed state, a certain return reaction force acts, and the door 9 is securely closed with respect to the fixed frame 11.

The push rod 5 which is selectively engaged with the fixing planes 7 and 8 is inserted vertically into the receiving hole 16 of the main body 1 with the rotary shaft 2, and is urged in the axial direction by the disc spring 6. I have. The adjusting screw 3 is screwed into the terminal screw portion 17 of the receiving hole 16, and the engaging portion 4 of the rotating operation tool of the head 11 is formed in a hexagonal concave portion, into which a hexagon wrench is inserted. The disc springs 6 are used by laminating 46 pieces.

[0012]

As described above, in the hinge device with the fixing function of the present invention, the two fixing planes 7 are provided at 90 ° intervals at the intermediate portion of the rotating shaft 2 inserted into the main body 1 fixed to the fixing frame 10. , 8, and the door 9 is fixed to both ends 12, 13 of the rotating shaft 2, and the flat end surface 5 a is fixed to the fixing flat surfaces 7, 8.
The push rod 5 which comes into contact with the rotating shaft 2
The door 9 can be stably and statically fixed in the closed state and the open state while being small and lightweight because the door 9 is vertically inserted into the main body 1.

Further, by compressing the disc spring 6 between the adjusting screw 3 screwed into the main body 1 and the push rod 5,
Since torque is applied to the rotating shaft 2, the adjusting screw 3
, The stationary fixing force of the door 9 can be easily adjusted.
