According to this, the present invention is largely fixed to the ceiling panel 6, the fixed frame 1, and inserted into the fixed frame 1, the door frame 2 and the opening and closing operation and opening and closing of the door frame 2 It consists of a hinge portion 4, the opening and closing device (5).

That is, the fixed frame 1 assembled with the frame bent in the vertical direction in the longitudinal direction to have a rectangular shape is installed so as to coincide with the surface of the ceiling panel 6 between the ceiling panels 6 provided on the ceiling of the building. do.

On the outer wall of the fixed frame 1, the coupling guide groove 101 is formed along the longitudinal direction so that the coupling plate 3 to be described later is coupled.

In addition, the bent groove 102 is formed in the lower portion of the coupling guide groove 101 vertically bent inwards, and the long side grooves 103a and 103b are formed on the vertical sidewalls of the bent groove 102, one side groove 103a. Is formed to penetrate horizontally in a rectangular shape, and the other long groove 103b is formed to penetrate horizontally in a rectangular shape, and an inlet groove 103b 'is formed vertically on the inner side of the long groove 103b so that the rotation shaft 401 is an access groove. It is configured to be detached to the long groove 103b along the 103b '.

The rotation shaft 401 inserted into the long grooves 103a and 103b is left with a free space on both sides, and thus the rotation shaft 401 is inserted into the long grooves 103a and 103b to rotate.

In addition, the bottom surface of the bending groove 102 to form a coupling protrusion 104 along the longitudinal direction.

Coupling protrusion 104 is configured such that both sides of the wall obliquely toward the center so that the piece 502 of the opening and closing device 5 to be described later through the two side walls of the coupling protrusion 104, the separation of the piece 502 And departures.

In addition, the lower surface of the engaging projection 104 is formed with a guide groove 105 to help screw the piece 502 of the opening and closing device (5).

The door frame 2 is configured to have a frame bent in the vertical direction of the longitudinal direction to have a rectangular shape to be inserted into the fixed frame (1), so as to open and close the rotation axis 401 of the hinge portion (4). Install.

The door frame 2 is formed with a coupling guide 201 groove along the longitudinal direction to the coupling plate 3 is coupled to the outer wall, the lower side of the coupling guide groove 201 is inserted into the tubular shape of one side is opened along the longitudinal direction The groove 202 is formed in line with the long groove 103.

In addition, the bottom of the door frame 2 is formed with a fixing groove 203 in the longitudinal direction so that the fixing projections 501a of the opening and closing lever 501 is fitted and fixed.

The coupling plate 3 is manufactured by bending a metal plate in a 'b' shape, as shown in FIG. 4, and is installed at four corners of the fixed frame 1 and four corners of the door frame 2, but fixed frame. (1) and the connecting guide grooves 101 and 201 formed on the outer walls of the door frame 2, respectively, by inserting the connecting plates 303 on both sides of the coupling plate 3, and configured to couple the frames together.

In addition, the coupling plate 3 forms an inclined portion 302 in which the uneven portion 301 is formed on the upper and lower portions of the curved portion, and the width of the connecting plate 303 becomes narrower from the center to both sides.

At this time, the shape of the uneven portion 301 is'

Figure 112012052838070-utm00003
' or '
Figure 112012052838070-utm00004
Can be configured in shape.

That is, the uneven portion 301 may have a shape or sawtooth shape in which the curve is alternately repeated, and in addition to the suggested shape, the uneven shape capable of solidifying the coupling between the coupling plate 3 and the frame may be modified in any form. It is possible to find out.

In addition, the middle portion of the concave-convex portion 301 is preferably a groove portion because the coupling plate 3 is a curved portion that is bent in a '-' shape.

In addition, the coupling plate 3 forms an opening 304 in the horizontal direction at the center of both connecting plates 303.

In addition, the present invention shows an embodiment in which the door frame 2 is provided with a coupling plate 3 having an opening 304, and the fixing frame 1 has a coupling plate 3 having no opening. , Crossing or repeating is possible.

Therefore, the coupling plate 3 has an opening 304 at the center of both connecting plates 303, so that the elasticity is good and the concave-convex portion 301 is provided in the curved portion, so that the coupling becomes stable.

On the other hand, the hinge portion 4 of the rotary shaft 401 protruding to the outside after coupling the rotary shaft 401 to both side insertion grooves 202 formed in the door frame 2, as shown in Figure 7 attached to the drawing The head is detachably coupled to the long grooves 103a and 103b formed in the bending grooves 102 of the fixed frame 1.

In this case, referring to FIGS. 5A to 5C, the process of coupling the door frame 2 to the fixed frame 1 will be described. First, the rotation shafts 401 are respectively coupled to both insertion grooves 202 of the door frame 2. The first rotation shaft 401 is inserted into the long groove 103a without the access groove 103b ', and the other rotation shaft 401 is inserted into the long groove 103b with the entrance groove 103b'. Therefore, it is mounted in the long groove (103b).

Therefore, the door frame 2 can be easily detached from the fixed frame 1.

In addition, the rotating shaft 401 may use the piece 401, but not limited to the piece 401, it can be used that can function as the piece 401 can be replaced.

In addition, the piece 401 is formed to be pointed toward the piece tail (401b) from the piece head (401a) and the body is configured to fit in the insertion groove (202).

That is, when the piece tail 401b is first inserted into the insertion groove 202 and then the body is inserted into the insertion groove 202, the installation of the piece 401 is completed by completing the installation of the piece 401 stably and quickly. You can do it.

Therefore, the door frame 2 is rotated about the piece 401 of the hinge portion 4 to perform the opening and closing operation.

On the other hand, the opening and closing device 5 is an opening and closing lever 501 is installed on the lower surface of the engaging projection 104 of the fixed frame 1 at the position facing the hinge portion 4 as shown in the accompanying drawings, Figure 6, It consists of a piece 502 for rotatably fixed to penetrate both sides of the opening and closing lever 501.

At this time, the piece 502 for fixing the opening and closing lever 501 is screwed with both side walls of the engaging projection 104 formed on the bottom surface of the bending groove 102 of the fixing frame 1, preventing separation and separation do.

In addition, the opening and closing lever 501 of the opening and closing device 5 forms a fixing protrusion 501a at the bottom of the lever end, and the fixing protrusion 501a of the door frame 2 when the locking lever 501 is turned and locked. Since it is fixed to the fixing groove 203 formed on the bottom surface, the locking becomes stable.

Therefore, the opening and closing device 5 composed of the opening and closing lever 501 and the piece 502 rotatably fixed to penetrate both sides of the opening and closing lever 501 in the fixed frame 1 at the position opposite to the hinge part 4 is provided. Installation of the opening and closing device 5 is easy and there is an advantage that the opening and closing of the door frame 2 is easy.

The door panel 2a is fitted to the door frame 2 to finish.

In the above described and described with respect to the preferred embodiment of the present invention, this invention is not limited to the specific embodiments described above, it is usually in the technical field to which the subject innovation belongs without departing from the gist of the subject innovation claimed in the claims. Various modifications or applications may be made by those skilled in the art, and such modifications or applications may not be individually understood from the technical spirit or prospect of the present invention.
