Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an opening/closing device for a closed part of a building, in which a glass door 2 is disposed on the outdoor side of an entrance part 1 of the building, and a metal outdoor right 5b exposed to the outdoor side is connected to the indoor door. An inner door 5 is formed by attaching a metal plate 4 facing outdoors to a frame body 5a consisting of an indoor wall 5c made of wood or synthetic resin exposed on the inside, and attaching an interior material 3 facing indoors. This relates to an opening/closing device for a building entrance, which is configured to freely open and close the indoor side of the building entrance 1 using the inner door 5.

Conventional opening/closing devices for building openings have had storm doors placed on the outdoor side and glass doors placed on the indoor side.

However, in such conventional examples, since the glass door is located on the indoor side, dew occurs on the glass door, and if the rain door is on the outdoor side, the glass door must be opened and closed each time the rain door is opened and closed. In addition, the shutters are opened and closed at night or early in the morning, but there is a problem in that the cost of opening and closing the shutters is large and a nuisance to the neighborhood.Furthermore, if the shutters are exposed to the outside, the appearance is undesirable. There are many people who dislike this problem, and also because the shutters are left open during the day.
Thick curtains are required. On the other hand, it is not possible to install rain shutters outdoors in snowy or cold regions, and it is also difficult to install rain shutters on the outdoor side of apartments and condominiums. There are various problems in terms of security, fire prevention, and strength at the entrance of a building, and also in this case, there is a drawback that thick curtains are required. The present invention was invented in view of the above-mentioned drawbacks of the conventional shutters, and its purpose is to provide the same security, fireproofing, and strength as conventional shutters, but The glass door is not exposed to the outdoors, the appearance is not unsightly, and the interior material of the inner door and the indoor wall of the frame are located on the indoor side, so the glass door is located directly on the indoor side. In comparison, fog does not form, and even when opening and closing the inner door at night or early in the morning, the sound of opening and closing the inner door does not become louder to the outside, so it does not disturb the neighbors, and the inner side is made of interior materials. By closing the indoor side of the opening with the inner door, it is possible to completely shield the room and make the indoor surface feel the same as the wall, eliminating the need for thick curtains and creating the same feeling inside the room as with glass doors. It can be used to change the condition from one state to the next without glass doors, and can also be used in closed areas of buildings, such as in snowy areas, cold regions, apartments, condominiums, etc., where storm shutters cannot be installed conventionally. Our objective is to provide a switchgear.

The present invention will be explained in detail below with reference to Examples.

A sash frame 6 is attached to the outdoor side of the entrance part 1 of the building, and a glass door 2 is attached to the sash frame 6 so that it can be opened and closed in a sliding manner. A lintel 7 and a sill 8 are provided above and below on the indoor side of the closing part 1 of the building, and the lintel 7 and sill 8 are twice or more than twice the horizontal length of the entrance part 1. , both ends of the lintel 7 and the threshold 8 are storage rails 9 that protrude along the wall to the left and right of the opening 1, and the length of each storage rail 9 is the same as the opening. It is 1/2 or more of the horizontal length of part 1. Kamoi 7
Two inner doors 5 are slidably arranged between the left and right inner doors 5 and the sill 8, and when the left and right inner doors 5 are stored in the storage rail section 9, the indoor side of the opening section 1 is opened. Rail part 9 for storing the inner door 5
By pulling it out from the inner door 5, the indoor side of the entrance section 1 is closed. The inner door 5 has a metal plate 4 mounted inside the frame 5a facing outdoors, and an interior material 3 facing indoors.
It is formed by attaching it. The frame body 5a of the inner door 3 is formed by sewing together an outdoor side paddle 5b made of metal exposed to the outside and an indoor side paddle 5c made of wood or synthetic resin exposed to the indoor side. In other words, in the embodiment shown in FIG. 5, a steel convexity A is formed on one side of the indoor side camphor 5c, and this competing convexity A is formed on a steel concave B on one side of the outdoor side phase 5b. A frame body 5a is formed by ironing them together. In the figure, C and D are recesses into which the metal plate 4 and interior material 3 are inserted, respectively. As the interior material 3, for example, printed plywood or cloth is used. Further, as the metal plate 4, for example, a colored steel plate which is bent in a wavy manner and has a louvered appearance is used. Note that a core material such as a heat insulating material or a sound insulating material may be interposed between the metal plate 4 and the interior material 3 as necessary. The first river in the picture is a screen door. Normally, the inner door 6 is opened and the opening section 1 is opened and closed using only the glass section 2, but during the day when sunlight and ventilation are not required, or at night, the inner door 5 is closed and the opening section 1 is opened and closed. The interior side of the room is closed. When the inner door 6 is closed in this way, the existence of the inner door 5 provides the same security and strength as a conventional storm door, and since the outdoor surface of the inner door 5 is made of a metal plate 4, it is not the same as a conventional storm door. Fire protection is obtained, and in this case, when the frame body is on the outdoor side, the outdoor side box 5b made of metal is exposed, so that the fire protection is further improved. Moreover, when the inner door 5 is closed, the interior material 3 is exposed on the indoor side, so this interior material 3 becomes part of the wall, and the glass door is not exposed to the interior.
It will feel as if the room does not have a glass door, and even though there is a glass door 2, a room with only walls without glass door 2 will appear, and a room with glass door 2 or a room with glass door 2 will appear. A room with only walls without a door 2 can be revealed by simply opening and closing an inner door 5. In this case, the interior material 3 of the inner door 5 may have the same finish as the walls of the room, or may have a different finish. Furthermore, although a metal plate 4 was attached to the outdoor side of the inner door 5 for fire prevention and crime prevention, and the metal outdoor wall 5b was exposed, there was no interior material 3 and wood or synthetic resin on the indoor side. Since the indoor side right 5c is exposed, fog does not form on the inner door 5 on the indoor side. Furthermore, since the inner door 5 can be opened and closed directly from inside the room without opening the glass door 2, the operation can be easily performed, and since the inner door 5 is not directly exposed to the outside, the appearance does not become unsightly. By the way, when opening and closing the inner door 5 at night or early in the morning, the presence of the glass door 2 prevents the opening and closing noise of the inner door 5 from being loud to the outside and causing no nuisance to the neighborhood. Furthermore, when the indoor side of the opening 1 is closed with the inner door 5, it can be completely shielded and the interior material 3 is exposed on the indoor side, so there is no need to close the glass door 2 with a thick curtain as in the past. It is something. Also, if the inner door 5 is placed on the indoor side of the open section 1 as mentioned above, it may not be possible to install the shutter on the outdoor side as in snowy regions, cold regions, apartments, and condominiums, or Even in places where construction is difficult, since it is indoors, it is possible to construct an inner door 5 that has the same function as a rain door and has advantages that a rain door does not have. Although the above embodiment shows an example in which the glass door 2 can be opened and closed in a double-sliding manner, the glass door 2 is not necessarily limited to this, and other known structures such as a sliding window or a revolving window can be adopted. . Further, in the above embodiment, both ends of the lintel 7 and the sill 8 are used as storage rail portions 9, and the storage rail portions 9 at both ends are made to protrude along the wall to the left and right of the opening □ portion 1, respectively.
The inner door 5 is stored on the left and right sides, but as shown in Fig. 6, only one end of the Hahajima residence 7 and the threshold 8 is used as a storage rail part 9, so that the inner door 5 is stored only on one side. You may also do so. Furthermore, the figure shows a double-walled indoor wall 1.
1 prevents the stored state of the inner door 5 from being seen from inside the room. Of course, the indoor wall 11 may not be provided. In the figure, 12 is the outdoor wall. Further, 13 is a flooring material. Reference numeral 14 in the figure indicates a contact material for the inner door 5.
