Abstract

PURPOSE: To facilitate the fixing work of a door, by providing a protrusion which can be recessed as a rotary guide and a protrusion as a rotary axial center in the fixing side member and providing guide grooves in which respective protrusions are fitted in and a notch in the rotary side member. CONSTITUTION: A ventilation door 14 is horizontally pushed in and a protrusion 6 is positioned in the depth of a notch 10. And after that, the door 14 is raised at the front side. In this case, the protrusion 5 is once recessed and projected into the groove at the position of guide groove 11 and the door 14 is set in the fitted and opened condition. Then when the door 14 is raised from the position, the protrusion 5 moves within the groove 11 around the protrusion 6 as the center and the rotary side member 3 is rotated and the door 14 is closed perpendicularly. In this way, the door can be easily fixed by oneself and stably opened and closed. Since the fitting tools are inconspicuous, the external appearance can be improved.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting for a ventilation door or the like.

2. Description of the Related Art In some cases, a horizontally long ventilation door is provided above an entrance door or the like. Such a ventilation door is provided so as to be openable and closable by supporting both sides thereof by a folding opening / closing lever.

However, in the structure in which the door is supported by the folding opening / closing lever as described above, the door to which the opening / closing lever is attached must be supported while being attached to the opening side, which is very troublesome to attach. At the same time, since the lever is folded and the door is opened and closed, the operation cannot be performed smoothly, noise is generated, and the opening and closing lever is not noticeable. It is an object of the present invention to easily attach a ventilation door or the like so that it can be opened and closed well, and can be installed in a good appearance.

According to the present invention, a door attachment is provided with a first protrusion, which serves as a rotation guide and is provided so as to be recessed, and a second protrusion, which serves as a rotation axis, on one surface. The rotary side member includes a fixed side member, a cutout portion in which the second protrusion is located at the back, and a guide groove into which the first protrusion is inserted.

According to the present invention, the first protrusion is set in a recessed state, the second protrusion faces the entrance of the notch, and the rotary member surface is slid on the fixed member surface so that each member By being relatively moved by a predetermined position, the first protrusion projects into the guide groove, and the second protrusion is located at the back of the notch. Then, at this position, the first protrusion moves as a rotation guide in the guide groove with the second protrusion as the rotation axis, so that the rotation-side member is rotated with respect to the fixed-side member.
Therefore, by mounting the fixed-side member on the opening side and the rotating-side member on the door side, it is possible to mount the door to the opening and open / close the door in the mounted state in accordance with the above operation.

1 is a front view of a door attachment of the present invention, FIG. 2 is a rear view, FIG. 3 is a sectional view, and FIG. 4 is a perspective view. The door attachment 1 is a substantially rectangular fixed side member 2 made of a metal piece.
And the rotation side member 3. A first protrusion 5 as a rotation guide and a second protrusion 6 as a rotation axis are provided on one side surface of the fixed member 2 so as to protrude. The first projection 5 is provided so as to elastically project by a spring 8 mounted in a spring mounting body 7 formed to project on the other side surface of the fixed-side member 2 so that it can be pushed. . Further, the fixed member 2 is provided with four mounting holes 9. The rotation side member 3 is formed with a notch 10 in which the second protrusion 6 is located at the back and a guide groove 11 into which the first protrusion 5 is inserted. Further, the rotation-side member 3 is provided with four mounting holes 12.
The stationary member 2 and the rotating member 3 are separable from each other. As shown in FIG. 4, the stationary member 2 is attached to the frame portion 16 of the mounting opening 15 of the ventilation door 14, and the rotating member 3 is ventilated. It is used by being attached to the lower side surface of the door 14. Actually, the fixed member 2 is the frame portion 1 on the opposite side of the mounting opening 15.
The rotary side member 2 is also attached to the lower side surface on the opposite side of the ventilation door 14 so as to correspond to the fixed side member 2. Then, with the ventilation door 14 horizontal, the second protrusion 6 faces the entrance of the cutout portion 10, and from that state, the ventilation door 14 is pushed horizontally so that the second protrusion 6 is deep inside the cutout portion 10. Position, and the front side of the ventilation door 14 is lifted from that position. When moving the ventilation door 14,
Since the inclined portion 18 is provided along the edge portion of the rotation-side member 3, the first protrusion 5 is once recessed by the inclined portion 18, and the guide groove 11 is provided at a position facing the guide groove 11.
Project inside. Then, the first projection 5 is locked in the guide groove 11, so that the ventilation door 14 is maintained in its attached state. The above-mentioned attached state, that is, the state shown in FIG. 4 is a state in which the ventilation door 14 is opened. From this position, the ventilation door 14 is pushed further from the front side in the direction of the arrow, so that the second protrusion 6 is centered. As a result, the first protrusion 5 is guided and moved in the guide groove 11 to rotate the rotation side member 3, whereby the ventilation door 14 is closed in the vertical state.
When opening, the upper part of the ventilation door 14 is pulled down and opened to the position shown in FIG.

According to the present invention, the fixed-side member is attached to the predetermined position of the mounting opening, and the rotary-side member is attached to the predetermined position of the door, and the first protrusion is in the recessed state, and the first portion is provided at the entrance of the cutout The second projection is exposed, and the rotation-side member surface is slid on the fixed-side member surface so that the respective members relatively move to a predetermined position, so that the first projection is projected and the inside of the guide groove. And the second protrusion is located deep inside the notch,
In this way, the door can be easily attached by one person, and at that position, the first protrusion moves as the rotation guide in the guide groove with the second protrusion as the rotation axis.
The door can be opened and closed stably. As a result, it is possible to obtain a mounting structure such as a ventilation door that is easy to install, has a stable opening and closing operation and is quiet, and has a design that is excellent because the mounting tool is not conspicuous. Etc. can be widely used in various places.
