Description

The door of crime prevention

The present invention is mainly installed in various doors, such as apartments or houses, and can receive various deliveries (freight) such as food and household goods (hereinafter referred to as "delivery") delivered from the outside without opening the door. Regarding the security door that is present, more specifically, the installation of the delivery door can be made easily, the delivery can be delivered even if there is no person in the house, and also the delivery of long delivery that is difficult to receive conventionally made easily It is invented and improved.

Normally, when a visitor (deliveryer) presses the bell from the outside, the occupant naturally checks the visitor's identity. As a means for checking the visitor, the door is provided with an auxiliary window made of a small lens. An image of the visitor is output through the monitor.

Such a visitor's identification device can directly identify the visitor to prevent crime by an unjust visitor, but despite the obvious identification in the near future, unexpected crime in various delivery processes or visitor visits, etc. There are many examples of the occurrence of this accident, and the accident is a single person or a weak person in the house alone is a frequent occurrence.

These crimes cause considerable inconvenience and psychological and psychological damage to both by distrusting each other and those who make delivery orders in the simple delivery process of food, gifts and flowers.

This means that even if the identity of the orderer is certain, the delivery person cannot be completely trusted, and conversely, the delivery person may also receive unnecessary suspicion from the orderer, resulting in psychological and mental damage to both. .

In particular, in the case where a single person (mainly single woman) or a weak person lives alone, the above-mentioned crime may be more serious, which is caused by the visitor committing an accidental crime according to the surrounding situation.

In addition, in the case of mainly women, it is often desired to prevent the above-mentioned concerns and to receive a delivery item without exposing itself from the outside when the visitor visits. In order to effectively prevent crime, it is necessary to develop the most fundamental method, that is, to identify only the identity of the delivery person and the delivery and to receive the delivery to the room without opening the door.

For reference, in the past, an auxiliary door is installed at the lower side of the door which may be related to the present invention so as to deliver milk or newspaper from the outside to the room without opening the door, but it is a small standard such as milk or newspaper. It is not suitable for delivery of deliveries, such as flowers or foods, because only the goods can be delivered and are simply pushed from the outside into the room.

Therefore, the present inventor has previously applied for and registered a security door having a different purpose from the auxiliary door (Patent No. 0343312).

In the above invention, in the door provided with the delivery door so that the delivery can be delivered from the outside without opening the door, the delivery door is a hinge axis on the door, the opening and closing doors of the outside / inside to open and close the hinge axis It is composed of a plate that is connected between the two folding doors (folding hinge) between the opening and the door to place the delivery, can be delivered to the interior from the outside without opening and closing the door in the delivery process of the goods, etc. This prevents crimes that may occur accidentally or deliberately during delivery of the deliveries, and concerns from outside delivery orders, especially if only a single person or a weak person is left alone in the house. Can be free from personal threats to various crimes In addition, it is possible to achieve a security effect, and in the case of women, etc., it is possible to receive a delivery from the outside without exposing itself from an external delivery person. Many benefits and effects could be expected in many ways, including prevention.

However, in the case of the above-described security door configuration, it is difficult to provide a threshold for soundproofing and windproof between interior / exterior opening and closing doors due to the structural characteristics of drilling holes in the doors and installing delivery doors to be rotatable.
