Figure is a schematic representation of the appearance of the plan view.

Referring to Figures 1 to 4, the door-tight close-type locking door according to the present invention may basically comprise a door frame 100, the hinge 200 and the door 300.

The door frame 100 may include a substantially columnar shape having a length along a direction perpendicular to the ground. The door frame 100 performs a function of fixing and supporting the hinge 200 and the door 300 to be described in detail.

The hinge 200 has a coupling surface 210 coupled to the door frame 100 and has a rotational connection portion 220 protruding in one direction of the door frame 100, and may be provided at least one. At this time, the engaging surface 210 of the hinge 200 may be formed to include the width of the cross section perpendicular to the height direction of the door frame 100 or may be formed to a less than the width. That is, the coupling surface 210 of the hinge 200 may be formed to be equal to the vertical cross-sectional area of the door frame, or may be formed larger or smaller.

On the other hand, the rotation connection portion 220 of the hinge 200 protrudes in one direction of the door frame 100, so that the rotation connection shaft 225 of the rotation connection portion 220 forms the same axis as the rotation axis 310 of the door 300 Rotating connector 220 may protrude. At this time, as an example of the coupling method for rotating the door 300, although not shown in the drawing, the rotary connecting shaft 225 and the rotary shaft 310 are all opened to insert a separate rod shaft to penetrate them through the door 300 may be rotated. Alternatively, the rotating shaft 310 is inserted into the rotating connecting shaft 225 opened in a state of protruding in the direction of the rotating connecting shaft 225, or, on the contrary, the rotating connecting shaft 225 protrudes in the direction of the rotating shaft 310. The door 300 may be rotated by being inserted into the rotating shaft 310 which is opened.

In addition, the hinge 200 may include a coupling to at least one of the upper end and the lower end of the door frame 100. If the hinge 200 is coupled to both the upper end and the lower end of the door frame 100, it may provide more firm coupling force. In addition, as shown in Figures 1 and 3, it may be coupled to the stop of the door frame (100). However, the present invention is not limited thereto, and may be additionally coupled between the upper end and the lower end of the door frame 100 in consideration of the area of the coupling surface 210, the weight of the door 300, and the like.

The door 300 is rotatably assembled to the rotary connection portion 220 and is configured such that one end of the rotating end portion 320 is convex toward the door frame 100. The cross section of the rotary end 320 may be formed to include a semi-circular shape. That is, since the door 300 is rotated while the rotating end 320 convex toward the door frame 100 having a semicircular cross section is close to the door frame 100, the gap space between the door frame 100 and the door 300 is minimized. Can be. Therefore, it is possible to prevent the pinching of the hand into the gap space.

The rotary end 320 may be integrally formed with or detachable from the door 300. If the rotary end 320 is detachable from the door 300, since only the door 300 can be replaced, the door 320 can be replaced with a door 300 having various patterns according to taste, or by damage. As a replacement, only the door 300 may be easily replaced.

On the other hand, the corner consisting of two sides close to the door 300 side of the door frame 100 according to the present invention, the concave edge concave inside the door frame 100 in a shape corresponding to the rotary end 320 of the door 300 ( 110 or the two sides may be formed as a vertical edge 120 vertical.

Here, referring to FIG. 2, when the edge of the door frame 100 is formed as a concave edge 110, the rotation axis 310 of the door 300 is located at the intersection 150 where the virtual extension lines of the two sides meet. It is characterized by. As such, when the rotation shaft 310 is positioned at the intersection point 150, the door 300 may be rotated with a rotation radius in the range of 0 to 90 °.

On the contrary, referring to FIG. 4, when the edge of the door frame 100 is formed as the vertical edge 120, the rotation axis 310 of the door 300 is positioned on an imaginary extension line of one of the two sides. It is characterized by. As such, when the rotation shaft 310 is positioned on the imaginary extension line, the door 300 may be rotated with a rotation radius in the range of 0 to 180 °.

In addition, although not shown in the drawing, the door-frame close-type locking door according to the present invention may be fixed when the door 300 is opened by rotating the door 300 at a predetermined angle or more. In some cases, it is necessary to live with the door 300 open, or the door 300 is forcibly closed by the wind. Therefore, a means for fixing the door 300 is needed to solve these problems. For example, to enable this, the upper end of the door 300 is mounted with a round bar-shaped fixing member protruding by a spring, the hinge 200 is formed with a fixing groove into which the fixing member is inserted. At this time, when the fixing groove is formed in the part where the fixing member is located when the door 300 is opened at a predetermined angle or more, the fixing member is pushed into the door 300 by touching one side of the hinge 200. Entering and protruding by the spring is inserted into the fixing groove can be fixed to the door (300). On the other hand, one side of the fixing member may be further formed with a handle portion exposed to one side of the door 300, it will be able to release the fixed door 300 by holding and pulling down the handle portion.

In addition, although not shown in the drawings, the door-frame close-type locking door according to the present invention is formed between the door frame 100 and the door 300, in addition to the door frame 100, the hinge 200 and the door 300. It may further comprise a configuration of the insertion member inserted into the gap space. The insertion member may be formed in a shape corresponding to the gap space and inserted into the gap space. For example, the insert member may be made of various materials such as cloth, vinyl, rubber, silicone, plastic, mohair, and the like. Therefore, the insertion member may perform a function of preventing the inflow and outflow of contaminated air, dust, noise, etc., the door frame close-type jam-proof door according to the present invention, with the prevention of pinching of fingers, more effective dust, smoke, Soundproofing and the like can be performed.

While the embodiments of the present invention have been described in more detail, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention. Therefore, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention but to describe the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments.

Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive. The scope of protection of the present invention should be interpreted by the claims, and all technical ideas within the scope equivalent thereto should be construed as being included in the scope of the present invention.
