Description

The present invention relates to a mailbox, and more specifically, when it is necessary to refuse to post a leaflet advertisement or the like before moving in and when the user is absent for a long period of time, the inlet of the mailbox can be closed for a required period. The present invention relates to a mail box with a function of preventing absent-minded boxing, which is provided with a possible inlet flap lock means.

In daily life, in order to receive postal items and other deliveries, not only collective housing such as condominiums and apartments and detached houses, office buildings, etc. There is.

Although various types of conventional mailboxes are used, as a basic form, there are a mail box body having a box structure and a mail piece formed on the front plate of the mailbox box body. The container is composed of an input port for mailing, a storage chamber for storing the mail and the like mailed from the input port, and an outlet for taking out the mail and the like.

By the way, in the mailboxes of unoccupied houses such as houses and condominiums that have been away for a long time, in addition to mail and newspapers, a large amount of thrown leaflet advertisements are put in place. In particular, apartments are likely to be targeted, and as a result, leaflet advertisements, etc. overflow from the mail box and are scattered around, impairing the aesthetics, and may cause fire and arson. Moreover, the absence of a resident becomes clear from the state where leaflet advertisements and the like overflow from the mail box, which may be a hotbed of crime.

Therefore, under such circumstances, it has been considered for a long time to formulate measures for preventing unauthorized insertion of leaflets, but in addition to the above-mentioned circumstances, it is important and urgent for management of apartment houses. It's a problem. Under such circumstances, various types of mail refusal tools have been conventionally proposed to prevent the insertion of leaflet advertisements and the like into post boxes such as unoccupied houses and long-term absent houses.

For example, Japanese Unexamined Patent Application Publication No. 2000-232933 (hereinafter referred to as "Patent Document 1") has a horizontally-long rectangular insertion port as a device for rejecting insertion into an existing mail box and the lower end of the insertion port. Is to be mounted on a mail box having a cross-sectional structure of an inlet that is bent at a predetermined depth and is located at the lower edge of the backside of a horizontally long inlet-covered front plate having a size that covers the inlet. Then, a structure in which a lower edge hooking structure of the charging port is configured is described.

However, the boxing refusal device described in the above-mentioned Patent Document 1 has a structure in which the lower edge of the loading slot cannot be attached unless it is a mail box having a cross-section of the loading slot in which the lower edge is bent at a predetermined depth at a right angle as described above. However, there is a drawback that it is not possible to deal with various mailboxes that have been diversified in recent years.

Further, it is described that such a mailing refusal device can be removably mounted, but a lower edge locking structure is required at the charging port for locking it at the lower edge of the charging port, and there are also two types of folding claw structure. It requires a complicated structure.

Further, Japanese Patent Laid-Open No. 2003-93215 (hereinafter referred to as "Patent Document 2") discloses a flat plate-shaped front covering member having a size capable of closing the charging port in a non-charging state, and the charging port. A flat plate-shaped rear surface support member having an engaging portion that can pass through and is in contact with the rear surface portion of the lower edge of the charging port, and the front cover member and the rear surface support member are connected to each other so that the facing interval and the facing angle can be changed. There is described a boxing refusal tool that includes a bolt and a nut and that is provided with a space holding means that prevents the front cover member and the back surface support member from closely contacting each other at a position facing the engaging portion of the back surface support member.

However, the boxing refusal device described in Patent Document 2 also has a problem in that the structure is complicated and the mounting work requires a long time, so that it is difficult to mount it easily.

Further, Japanese Utility Model Registration No. 3093560 (hereinafter referred to as "Patent Document 3") describes a mailing prevention device which is made of a sheet made of polypropylene resin or the like and is assembled by bending it into a predetermined shape. It is described that the folded sheet is attached by inserting the insertion portion of the folded sheet from the slot.

However, the boxing refusal tool described in Patent Document 3 uses a material made of a synthetic resin, has a problem in strength, may be broken, and has a point to be practically improved. Has been done.

Further, none of these proposals specifically made a mailing refusal device for closing the input port, and did not use the flap of the input port.

Under such circumstances, the inventors of the present invention have used a flap (opening/closing lid) provided at the inlet of the mail box as a device for a block for inserting a mail box such as a leaflet advertisement that has a simple structure and is easy to install and remove. (Hereinafter, the same in the present specification and the like)) has been proposed (see Patent Document 4).

However, the mailing refusal tools described in Patent Documents 1 to 4 are all applied to the existing mail box as described above, the structure is complicated, and the mounting work is complicated. However, there is a problem that it cannot be attached by a simple operation.

Therefore, it has been earnestly desired to develop a mail box having a simple structure and incorporating a locking means which can be closed by an easy operation when it is necessary to close the input port.
