Description

[Detailed explanation of the invention] This invention is applicable to cases where a reinforced concrete house or other general building tilts during an earthquake, etc., and the frame of the door installed at the entrance becomes distorted, making it impossible to open or close the door. To enable emergency evacuation, an evacuation exit is provided at the bottom of the door, and the lower edge of the auxiliary door is attached to the lower frame edge of the door using a hinge, etc., so that it opens inward and downward, and this can be opened and closed from both the inside and outside. Don't try to get it,
The present invention also relates to a door which, when opened, allows safe entry and exit over the auxiliary door as a passageway.

Most doors installed at the entrances of reinforced concrete houses and other general buildings are hinged at one edge so that they fit within the frame of the entrance.
If the frame edge becomes distorted due to the building tilting due to an earthquake, etc., the outer periphery of the door will be strongly compressed by the frame edge and will not open, making it impossible to escape or requiring rescue from outside. This has the disadvantage of requiring a lot of effort and time, such as unnecessarily destroying or cutting it open, so the present invention is designed to provide an auxiliary door that can be easily opened and closed from the inside and outside of the door itself. By attaching it to the evacuation entrance provided at the bottom of the auxiliary door so that it opens inward and downward, it is possible to safely evacuate through the auxiliary door. If you explain about
1 is the door body, one side edge of which is attached to the frame of the building with a hinge 2, and a handle attached to the other side, which is similar to a conventional side-swinging door, but in this invention, the door body 1 A doorway 4 of an appropriate size is provided in the lower paneling of the doorway, and an auxiliary door 5 is attached to the lower edge of the doorway with a hinge or the like 6 so that it opens particularly inward and downward, and the lower edge is attached to the opposite side. A hooking piece 7 is provided on the upper edge of the door, and the hooking piece 7 is hooked onto a receiving fitting 8 on the door body side.

A hole 9 is provided in the upper corner of this auxiliary door 5, and a hook 10 is provided on the inner circumferential surface near the hole 9, to which a chain or rope for supporting and pulling the auxiliary door 5 inserted through the hole 9 is provided. One end of 11 is hung, and the other end is passed through a hole 12 provided at the edge of the doorway 4 of the door body 1 and corresponding to the hole 9 of the auxiliary door 5, and then hooked to a hook 13 provided on the outer surface thereof. It was decided to stop it.

This door body constructed as described above is used as an entrance/exit door for reinforced concrete houses, other general houses, offices, etc. by attaching it to the frame A with hinges 2 as shown in Figs. 1 and 2. However, in this case, the auxiliary door 5 is installed so as to open downward inward.

In other words, under normal conditions, the auxiliary door 5 pulls its support/pull chain or rope 11 from inside through the hole 9, pushes up its upper edge, closes the entrance/exit 4, and locks the upper latch piece 7 into the receiving part on the door body side. The metal fitting 8 is hooked and held.

In this way, if the building is tilted due to an earthquake or the like or the door frame A is distorted during use, and the door body 1 is strongly sandwiched between the frames A and cannot be opened, the auxiliary door If you remove the latch piece 7 of 5 from the bracket 8 on the door body side and pull it down,
Supporting and pulling chain or rope 11 pulled inside
is pulled out to the opposite side through the hole 9, and the auxiliary door 5 opens downward as shown by the chain line in FIGS. As a connecting corridor, it is possible to safely pass through and escape to the outside without tripping over the lower edge of the doorway 4 of the door body.

Next, the supporting and pulling chain or rope 11 is inserted into the hole 12 from the outside.
If you pull the auxiliary door 5 through the
The entrance/exit 4 can be closed as shown in FIG.

As described above, the present invention provides an entrance/exit at the bottom of the side-swinging door body, attaches an auxiliary door that opens inwards and downwards to the lower edge of the door, and allows the auxiliary door to pass through the holes provided in the auxiliary door and the door body. By supporting the support/pulling chain or the end of the rope, the auxiliary door can be opened and closed by operating it from both the inside and outside of the door, so even if the door itself cannot be opened in the event of an earthquake, etc. By simply removing the upper latch piece of the auxiliary door from the inside and pulling it down, the auxiliary door can be easily and quickly opened inward, and the user can safely escape by passing over it.

In addition, after escaping outside, the auxiliary door can be closed by pulling the end of the support/pulling chain or rope from the outside, which prevents people from entering and exiting even temporarily, preventing various disasters. can be prevented.
