The present invention relates to a mail box having a function of preventing a mail box out of office with a possible entrance flap lock means.

  To receive mail and other deliverables in daily life, not only apartment houses and apartment houses such as apartments and apartments, office buildings, etc., mail boxes are also widely used in ordinary houses. Yes.

  Various types of conventional mailboxes are used, but the basic configuration is a box-shaped mailbox box body and a mail piece formed on the front plate of the mailbox box body. It is comprised from the insertion port for posting, the storage room which accommodates the mailpiece etc. which were thrown from the said insertion port, and the taking-out port for taking out a mailpiece.

  By the way, mail boxes and newspapers, as well as a large number of throw-in flyer advertisements, are put in mailboxes of unoccupied houses such as houses and apartments that have been away for a long time. In particular, apartment buildings are easy to be targeted, and as a result, flyer advertisements overflow from the mailbox and are scattered to the surroundings, which not only significantly impairs the aesthetics but also may cause fire and arson. In addition, the absence of residents is clear from the state in which leaflet advertisements overflow from the mailbox, which may be a hotbed of crime.

  Therefore, under such circumstances, the formulation of measures to prevent unauthorized entry of flyer advertisements has been studied, but in addition to the above circumstances, it is also important and urgent in managing apartment buildings. It is a problem. Under such circumstances, various posting refusal tools have been proposed for preventing the insertion of flyer advertisements and the like into mailboxes such as unoccupied houses and long-term absent houses.

There is described a posting refusal tool that includes a bolt and a nut, and is provided with a spacing holding means for preventing the close contact between the front covering member and the rear supporting member at a position facing the engaging portion of the rear supporting member.

  However, the posting refusal tool described in Patent Document 2 is also complicated in structure, and requires a long time for attachment work, and has a problem that it is difficult to attach easily.

  Furthermore, Utility Model Registration No. 3093560 (hereinafter referred to as “Patent Document 3”) describes a post-proofing device that is made of a sheet made of polypropylene resin or the like and is assembled by being bent into a predetermined form. In addition, it is described that the folding sheet is inserted by inserting the insertion portion of the folded sheet through the posting port.

  However, the posting refusal tool described in Patent Document 3 is made of a synthetic resin material, which is problematic in terms of strength and may be destroyed. Has been.

  In addition, all of these proposals are specially created posting refusal tools that close the inlet, and did not use the flaps of the inlet.

  Under such circumstances, the present inventors have a simple structure and a flap (opening / closing lid) provided at the input port of the post box as a post box input block device such as a flyer advertisement that can be easily attached and removed. (Hereinafter, the same in this specification and the like)) was proposed (see Patent Document 4).

  However, the posting refusal tools described in Patent Documents 1 to 4 are all applied to the existing mailbox, as described above, and the structure is complicated, and the installation work is complicated. There is a problem that it cannot be mounted by a simple operation.

Accordingly, there has been a strong demand for the development of a mailbox that has a simple structure and that incorporates locking means that can be closed by an easy operation when it is necessary to close the slot.
