Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a ventilation door that is attached to the entrance of an apartment building or the like.

[Background technology]

In general, condominiums do not have very good ventilation, so especially in the summer, the entrance door is opened to ventilate the room. However, if the entrance door is left open like this, insects and the like will enter the room, so a screen door is installed at the entrance. However, since this screen door is installed so as to cover the entire surface of the entrance/exit opening, the entrance door remains completely open, causing the problem that people passing through the passage can see inside. Another problem was that installing the screen door required skill, making it difficult for amateurs to install it.

In order to solve the above problems, we installed an insect-proof ventilation auxiliary door on the outer frame of the entrance door, so that when the normal opening/closing door is left ajar, the opening/closing door and the auxiliary door protrude from the entrance in a planar triangular shape. There is a ventilation system designed to be combined with the above, and is disclosed in Japanese Utility Model Application Publication No. 13387/1987.

However, in the case of the above-mentioned prior art, the auxiliary door is attached to the outdoor side of the entrance so that when the entrance door is left ajar and the door chain is hung, the auxiliary door can close the gap in the door chain from the outside. Therefore, when the auxiliary door is not in use, it is designed to be stored along the outdoor wall, but since the auxiliary door remains exposed to the outdoors,
In addition to being very unsightly in appearance, there is a problem in that the auxiliary door is exposed to rain, dust, and dirt, which impairs the durability of the auxiliary door. In addition, in apartment buildings, etc., it is prohibited to install or modify any structure in the common area outside the entrance door without permission, so it is not possible to install an auxiliary door outside the entrance door, and the above-mentioned It is not possible to use such ventilation equipment.

[Purpose of invention]

This invention is a ventilation door that is easy to install and does not allow people to look into the interior of the room when in use, has a good appearance when installed, is highly durable, and is suitable for apartments, etc. The purpose is to provide something that can also be applied.

[Disclosure of invention]

This device includes a ventilation door main body in which a ventilation section is formed in at least a portion, and the installation side end of the ventilation door main body is inside the vertical frame on the opposite side from the installation side vertical frame of the entrance door. It is designed to be rotatably attached to the wooden part provided in the door using a mounting bracket, and a hole is provided at the open end of the door into which the tip of the shaft provided in the twist lock of the entrance door fits. and a hook that engages with a lever handle of the entrance door, and when the entrance door is opened, the shaft of the twist lock fits into the hole and the hook engages with the lever handle. By doing so, the gist of the ventilation door is such that its open end is kept in a butt position with respect to the half-open entrance door.

In other words, this ventilation door leaves the door ajar,
Since the door is used by blocking the space between the open end of the half-open door and the entrance edge, the inside can hardly be seen from the outside because of the half-open door. In addition, since it can be easily attached to the wooden part inside the mounting frame of the entrance using a mounting tool, even an amateur can easily install it.

Next, this invention will be explained based on examples.

In the figure, 15 is a stopper (hit).

In this configuration, the ventilation door main body 1 rotates as shown by a broken line A around its attachment side end 16, as shown in FIG. Further, the entrance door 8 rotates as shown by a broken line B around its mounting end 17. When using the ventilation door body 1, first open the entrance door 8, and then open the ventilation door body 1.
The ventilation door body 1 rotates from the position indicated by the chain line in FIG. 5 to the position indicated by the solid line, that is, from a state in which it opens inward along the wall surface on the indoor side to a state in which it opens outward toward the outdoor side. Next, the entrance door 8 is closed to a half-open state, the open end 12 is butted against the open end 13 of the ventilation door main body 1, and the hook 6 of the ventilation door main body 1 is engaged with the lever handle 10 of the entrance door 8, At the same time, the twist lock 11 is operated to maintain the end abutting state. In this way, the ventilation door 1 is put into use. In addition, in FIG. 1, FIG. 2, and FIG. 5, 18 indicates outdoor, 19 indicates indoor,
In addition, in FIG. 5, 20 indicates a structural frame,
The two-dot chain line indicates the beam.

In this way, when in use, the ventilation door 1 is substantially perpendicular to the passage 18a, as shown in FIG. Therefore, the inside cannot be seen from the outside. Further, since the ventilation door main body 1 can be easily attached to the mounting frame portion 13 using the pivot hinge 2, even an amateur can carry out the installation.

In addition, the above-mentioned ventilation door 1, when in use,
Triangular spaces are created above and below (see Figure 1), but in condominiums, etc., there is an entrance ceiling wall just above the upper space, and the floor is just below the lower space, so these spaces are Intrusion of insects etc. from the space is hardly a problem. For completeness,
Closing means such as a brush-like body (not shown) may be provided on the upper and lower end surfaces of the ventilation door body 1 and the entrance door 8.

FIGS. 6 and 7 are a perspective view and a horizontal sectional view showing the structure of another embodiment. That is, in this embodiment, insect screens 22 are installed above and below the ventilation door body 21.

is rotated within the range indicated by the broken line C shown in FIG. 9, and the ends of the door 8a are brought into contact with each other with the inward opening door 8a half-opened inward, and the door 8a is used in this state. Since the other parts are the same as the embodiments shown in FIGS. 6 and 7, corresponding parts are given the same reference numerals. While the conventionally used fully closed screen door could not be used in the case of an inward-opening door, the ventilation door of this invention can be attached to an inward-opening door in this way.

Note that in all of the above embodiments, the ventilation door body is provided with a louver and an insect screen, but it is also possible to provide only the louver or only the insect screen. Further, it goes without saying that other fixtures may be used in place of the lever handle and hook that maintain the open end of the ventilation door body and the end of the entrance door in abutting state. Furthermore, other opening/closing fittings may be used in place of the pivot hinge.

In addition, in the event of a fire, if the open end holder is configured to automatically release its hold when smoke or fire is detected, the entrance door will be activated as a door check at the same time as the release. It closes automatically, which is preferable.

[Effect of idea]

As described above, this invention includes a ventilation door main body in which a ventilation section is formed in at least a portion, and the installation end of the ventilation door main body is on the opposite side from the installation vertical frame of the entrance door. It is designed to be rotatably attached to the wooden part provided inside the vertical frame of the door using a fitting, and the tip of the shaft provided in the twist lock of the entrance door is fitted into the open end of the fitting. and a hook for engaging a lever handle on the entrance door;
When the entrance door is opened, the shaft of the twist lock fits into the hole and the hook engages with the lever handle, so that the open end thereof is kept in abutment against the half-open entrance door. Because of this, the interior is almost invisible from the outside.
Therefore, even at night when the room is bright and it is easy to see the inside from the outside with a normal entrance screen door, it can be used without worrying about people looking in from outside. In addition, since the installation part of the ventilation door body is made of wood, there is no need for professional work, and even an amateur can install it by themselves using screws, etc., and even if it is an existing entrance door, it can be easily installed after the fact. It can be attached to the holder and is thus extremely convenient to use. Furthermore, since there is no need to provide mounting frames on all sides of the entrance like in conventional entrance screen doors, the appearance will not be spoiled by the mounting frames even after the ventilation door is removed.

Moreover, the ventilation door body is
