The present invention relates to a safety door having a guide, and in particular, the gap between the door and the door frame can be filled with a door guard to prevent the user's body from being caught, and the rotation of the door during opening and closing of the door. It relates to a safety door with a guide that can reduce the operating noise by guiding.

In general, a hinge for a door used for a safety door is composed of a fixed bracket that is fixedly installed on the door frame and a rotating bracket coupled to the door, and the fixed bracket and the rotating bracket are coupled to be rotatable by a spindle.

Here, the spindle has a hole formed in one of the fixed bracket or the rotating bracket and the spindle is inserted in the other bracket, so the spindle is inserted into the hole and perturbed in the rotational direction, so that the door fixed to the rotating bracket is easily rotated.

Such a hinge used in the conventional safety door has a problem in that a gap is generated when the door frame and the door are connected to each other by a large door spaced from the door frame.

In addition, the hinge used in the conventional safety door is a gap between the door frame and the door is generated a child's fingers are often accidents occur, the gap is a problem that the efficiency of cooling and heating in summer or winter due to the gap have.

Key is provided with torsion springs and are formed to cover the fixing portion so that the circular bent guide for guiding the banding in the soil when a circular bending portion elastic deformation of the spring round Ocean.

However, such door jamming prevention device has to be installed on the door separately from the hinge, the installation is cumbersome, the cost is added, there is a problem of deteriorating the interior aesthetics.

As another prior art for improving this, as disclosed in Korean Patent Publication No. 10-1402822 "Hinges to prevent finger pinching, improved installation convenience and door system using the same" (registration date: 2014.05.27), A first rotating support provided on a lower portion of the cylindrical first protrusion and having a first door through-hole formed in a horizontal axis direction in the main body; A second rotary support having a cylindrical second protrusion provided on an upper portion thereof and having a second door through-hole formed in a horizontal axis direction in the main body; And a first interpolation groove corresponding to the first protrusion is formed at an upper portion thereof so that the first protrusion may be rotated in an interpolated state through an upper surface thereof, and the second protrusion may be rotated in an interpolated state through a lower surface thereof. A second interpolation groove corresponding to the second protrusion is formed at a lower portion thereof, and includes a housing in which a door frame through hole is formed in a direction perpendicular to the first door through hole and the second door through hole; The main body consists of a cylindrical first housing seating portion, a semi-cylindrical first door contact portion protruding from an upper surface of the first housing seating portion, and a first door through-hole formed in a direction perpendicular to a square side of the first door contact portion, The housing has a cylindrical structure having the same diameter as the first housing seating portion, the cylindrical through-hole connected to the first interpolation groove and the second interpolation groove so that the first projection and the second projection can be inserted in the center thereof. And a door frame contact portion protruding from the body so that a portion corresponding to the rear end of the door frame through hole is in surface contact with the door frame.

However, the safety door with a conventional guide is not only dangerous because the clearance space between the door and the door frame is caught by the user's body part (especially the finger), but also the body is hit by the edge of the door while the door is open. There is a possibility that noise may occur when the door hits the door frame as the door is closed, and the head part of the fastening member (screw) for fixing the hinge to the door and the door frame is exposed to the outside to hinder aesthetic aesthetics. There is a disadvantage in that it works.
