Description

この発明は、郵便物等の投入、投入された郵便物等の一時的収納、一時的に収納されている郵便物等の取出しの目的で設計されていて、上下に回動可能な取出し口開閉扉によって開閉可能とされる郵便物取出し口を有する郵便受け箱の構造に関するものであり、特に、受入室内の郵便物を取り出す際、取出し口を開放した状態位置に取出し口開閉扉を保持しておくように構成した郵便受け箱等における取出し口開閉扉の開位置保持機構に関するものである。 The present invention is designed for the purpose of loading postal items, temporarily storing inserted postal items, etc., and taking out temporarily stored postal items, etc. The present invention relates to a structure of a mail box having a mail outlet that can be opened and closed by a door, and in particular, when taking out mail in the receiving room, the outlet opening / closing door is held in a state where the outlet is opened. The present invention relates to an open position holding mechanism for an outlet opening / closing door in a post box or the like configured as described above.

周知のように、新聞あるいは各種郵便物等の配達物の投入、投入された郵便物等の一時的収納並びにこの一時的に収納されている郵便物等の取出しの目的で設計されている郵便受け箱は、略箱状の郵便受け箱本体に対して、その後面側に郵便物取出し口が形成されており、この郵便物取出し口を開閉する取出し口開閉扉が設けてある。このような構成になる郵便受け箱では、当該取出し口開閉扉が郵便受け箱本体に対して上下回動タイプのものであるため、受入室内に投入されている郵便物等を取り出す際、取出し口開閉扉の自重により該取出し口開閉扉が郵便物取出し口を閉じる方向に変移してしまうという問題を有していた。 As is well known, a mailbox that is designed for the purpose of loading delivered items such as newspapers or various postal items, temporarily storing the postal items that have been thrown in, and taking out the temporarily stored postal items. Has a post-entry outlet on the rear side of the substantially box-shaped post box main body, and an outlet opening / closing door for opening and closing the post-entry outlet is provided. In the mail box having such a structure, since the door opening / closing door is of a vertical rotation type with respect to the mail box main body, the door opening / closing door is used when taking out mails and the like put in the receiving room. There is a problem that the opening / closing door of the take-out port changes in the direction of closing the take-out port of the mail due to its own weight.

上記する従来の郵便受け箱において、受入室内に投入されている郵便物等を取り出す際、取出し口開閉扉の自重による変移を防止して、取出し口開閉扉を郵便物取出し口を開放した状態で仮保持させて、上記する問題を解決するアイデアとして、例えば、 特許文献１あるいは特許文献２に記載のような構成になる郵便受け箱が提案されている。 In the above-mentioned conventional mail box, when taking out mails and the like put in the receiving room, it is possible to prevent the door opening / closing door from changing due to its own weight, and to keep the door opening / closing door open with the mail door opening open. As an idea for solving this problem by holding the post box, for example, a mailbox having a configuration as described in Patent Document 1 or Patent Document 2 has been proposed.

この特許文献１あるいは特許文献２に記載の郵便受け箱によれば、上記する問題を解決するものの、例えば、特許文献１に記載のものは、スプリング１０によって付勢されたボール６を仮固定手段としたものであり、このような手段のものでは、まず第１に、構造が複雑で、設計が困難であり、第２には、スプリング１０によって付勢されたボール６による仮固定のための付勢力が、ポストの取出し扉４の両側縁を結ぶ方向に働く構成のものである点、さらにまた、取出し扉４の枢支軸３１から保持作用点（嵌合孔５とボール６）迄の距離が短いため、取出し扉４の自重によるトルクが大きく働いてしまうような構成である点などにより、仮固定の確実性に欠け、且つ、取出し扉４の自重により保持力が弱いなど、長期的な繰り返し使用により仮固定力が劣化するという問題点を有している。 According to the mailbox described in Patent Document 1 or Patent Document 2, although the above-described problem is solved, for example, the one described in Patent Document 1 uses a ball 6 biased by a spring 10 as a temporary fixing means. In such a means, first of all, the structure is complicated and the design is difficult, and secondly, an attachment for temporary fixing by the ball 6 biased by the spring 10 is performed. The point is that the force acts in the direction of connecting both side edges of the post extraction door 4, and the distance from the pivot shaft 31 of the extraction door 4 to the holding action point (the fitting hole 5 and the ball 6). Because of the short length, the torque due to the weight of the take-out door 4 is greatly affected, and thus there is no certainty of temporary fixing, and the holding force is weak due to the self-weight of the take-out door 4, and so on. By repeated use There is a problem that the temporary fixing force is deteriorated.

一方、前記特許文献２に記載の郵便受け箱は、同様にして郵便受け箱における取出し口開閉扉を開放状態で保持するためのものであり、郵便物受入れスペースを確保するべく、取出し口開閉扉を上下スライド式に構成したものである。この特許文献２に記載の郵便受け箱における取出し口開閉扉は、上下スライド式のものであって、本発明とは具体的な構成において異なる。なお、この特許文献２に記載のものは、構造が極めて複雑なものであり、構成部材が多い等の点において問題を有するものであった。 On the other hand, the mail box described in Patent Document 2 is for holding the door opening / closing door in the mail box in an open state in the same way, and in order to secure a mail receiving space, the door opening / closing door is moved up and down. It is configured to slide. The take-out opening / closing door in the mail box described in Patent Document 2 is of a vertical slide type, and differs from the present invention in a specific configuration. In addition, the thing of this patent document 2 has a problem in the point that a structure is very complicated and there are many structural members.
