Description

[Detailed description of the invention] Industrial field of application This invention relates to a mailbox used in the steel door of each apartment building.

Conventional technology Traditionally, in apartment complexes, mailboxes for all units are installed together on the first floor, but a mailbox is also installed on the steel door of each unit's entrance, and the mailbox installed in each unit is used as a newspaper receptacle. Often.

As shown in Fig. 2, this mailbox has a lid plate 3 pivoted to the insertion slot 2 of a steel door 1, which is always urged to close by a spring, and a receiving box 4 attached to the rear of the lid plate 3, which is located at the lower front of the lid plate 3. The mail receiving box 4 had an opening 5 for taking out the mail (some boxes also had the opening 6 at the bottom of the receiving box 4).

Problems that the invention aims to solve The conventional mailbox mentioned above is also used as a newspaper receptacle, but newspapers are almost twice as long and thick as mail even when folded, and the insertion slot 2 is Because of the narrow spacing, the newspaper 7 gets stuck on the front wall 8 of the receiving box 4 as shown in FIG. 2 and cannot be fully inserted, so the lid plate 3 is used with it open. As a result, its performance as a fire door was significantly reduced, and the temperature inside the room dropped in the winter due to wind blowing in from outside as shown by arrow A. Also, newspaper 7
Since it is delivered in the state shown in FIG. 2, it is difficult to take it out from the indoor side, and when it is taken out, the cover plate 3 is forcefully closed by the spring, making a loud noise.

Means for solving the problem The means of this invention to solve the above problem is to attach a receiver box to the opening of the steel door, make the upper end of the receiver box an open part, and keep this open part closed at all times.
It consists of a mailbox for a steel door, in which the upper end of a rotary lid having a fan-shaped side cross section is rotatably pivoted to the upper end of the open part so that only one opening is opened when in use.

Embodiment An embodiment of this invention will be described based on the drawings.

A receiver box 12 is attached to the opening 11 of the steel door 10 that protrudes forward and backward to the extent that it does not overhang the handle. The lid 14 is rotatably pivoted 15, and mohair 18 is installed between the upper edge 16 of the receiving box 12 and the bottom 17 of the rotary lid 14 to prevent air from going in and out. Further, mohair 18 is similarly attached between the upper end 19 of the opening 11 and the upper end of the rotating lid 14.

The rotary lid 14 has a built-in weight 20 in its bottom 17, and when the slope 21 is pushed, it rotates and allows newspapers 7, etc. to be thrown into the receiving box 12.
The other slope 22 then hits the upper end 19 of the opening 11 of the steel door 10 and cannot be rotated any further, so that one opening or the other opening 23 is always closed and the opening 11 is always closed. It is constructed so that it cannot be inserted inside or outside. A steel opening/closing lid 25 is pivotally mounted below near the bottom 24 of the receiving box 12, so that mail etc. accumulated in the bottom 24 can be taken out. Note that if the opening/closing lid 25 is made of a transparent plate, it is convenient because the presence or absence of mail etc. can be confirmed from the outside.

To use this mailbox, please insert 7 newspapers from outside.
to push the slope 21 of the rotating lid 14. Then, the rotating lid 14 rotates as shown by the chain line in FIG. 1 and falls directly onto the bottom 24 of the receiving box 12. At this time, the rotating lid 14 keeps the opening 23 at the top of the receiving box 12 closed, and prevents wind from flowing in from the outside. When the newspaper 7 falls to the bottom 24, the rotary lid 14 is returned to its original position by the weight 20.
Next, when the slope 22 of the rotating cover 14 is pushed from inside, the rotating cover rotates in the direction opposite to the chain line, and the user moves the hand toward the receiving box 14.
Since the newspaper 7 can be placed inside the newspaper 7, the newspaper 7 can be pulled up and taken out from above.

Effects of the invention This invention consists of the above-mentioned means, so when the newspaper is thrown in, the rotary lid is pushed by the newspaper and rotated to the vicinity of the other mouth, so that the newspaper can be thrown in from the widely opened mouth downwards. The newspaper never gets stuck and always falls to the bottom of the receiving box, with the top end close to the mouth.

Therefore, when the rotary lid is pushed from the indoor side, the rotary lid rotates and the mouth can be opened wide and the newspaper can be easily taken out. At that time, since the side cross section of the rotating lid is fan-shaped, the other opening of the receiving box is always kept closed even when the rotating lid is rotated, so there is no communication with the outside when the opening is opened or closed. Since there is no wind blowing into the room, the temperature in the room does not drop due to drafts in the winter. In addition, since the rotating lid rotates back and forth around its upper end to open and close the mouth, when a newspaper is taken out, the lid closes abruptly, making a loud noise and causing discomfort, unlike conventional lids with springs. Never give up. Furthermore, the steel doors at the entrances of apartment buildings are required to function as fire doors, but this design eliminates the need for newspapers, etc., to be stuck open on the cover plate, as in the past, so mohair is used instead. By using a noncombustible material, it can exhibit effective performance as a fire door.
