Hinges for doors {HINGE FOR DOOR}

The present invention relates to a hinge for a door, and more particularly, to a hinge for a door, more specifically, by using a fixing member to engage the door coupling member with the door, it is possible to control the minute clearance between the door frame and the door even after the door is constructed, To a hinge for a door which is capable of enhancing a sense of beauty by engaging a cover as much as possible so as to conceal the joining structure of the fixing member.

Generally, a hinge is a hinge member commonly referred to as a hinge, which is widely used for a door, a window, and a case for storing an article, which is fixed between a door and a door frame so as to distinguish between the inside and the outside of the door. Hinges are usually made of wood, It is a hinge structure applied to a door structure made of steel material, copper material or plastic material.

Such a hinge is generally composed of two mounting brackets and a central shaft. The mounting brackets are each provided with a plurality of mounting holes for mounting the door bracket with the fastening bolts.

Further, a holder is formed along one side of the mounting bracket. The holder is alternately formed at opposite positions of the mounting bracket. The holder is bent in a cylindrical shape, and the center shaft passes through the holder. In the conventional hinge, the mounting brackets are mounted on the door and the door frame, respectively, so that one mounting bracket is rotated about the central axis together with the door, and the other mounting bracket is fixed to the door frame.

The hinge for adjusting the angle, which has been conventionally considered, is a hinge capable of adjusting and controlling the opening angle of the door, which is a registered utility model No. 20-0391475.

The Registration Utility Model No. 20-0391475 is a hinge comprising a fixed attachment plate and a rotation attachment plate which are coupled in a state of wrapping a pin shaft and is formed to control the rotation angle of the rotation attachment plate on the fixed attachment plate And a rotation control unit for stopping rotation of the rotation attachment plate when the rotation attachment plate is rotated to a predetermined angular range when the rotation attachment unit is rotated to a predetermined angular range, The control means includes a fixed engaging portion protruding upward or downward on at least one of the upper surface and the lower surface of the fixed support portion which is projected at one end of the fixed attachment plate and covers the pin shaft in a state of fixing the pin shaft, At least one of the upper surface and the lower surface of the rotary support portion, which protrudes at least at one end of the plate and surrounds the pin shaft in a rotatable state, When the rotary attachment plate is protruded upward or downward to allow the rotary operation to be performed within a set angular range during the rotation operation of the rotary attachment plate and to deviate from the set angular range, And a rotation control unit for controlling the rotation of the motor.

Therefore, the opening angle of the hinge can be adjusted, thereby preventing an accident occurring in the process of opening the door.

However, in the above-mentioned conventional technique, it is difficult to straighten the door when the door is not properly aligned after the door is installed, and also the door-side connecting portion and the fastening member of the hinge are exposed to the outside, There was a problem.
