Description

[Detailed Description of the Invention] (Technical Field of the Invention) The present invention relates to an insertion port assembly provided in a door, and in particular, an insertion port assembly that can be attached to a door insertion hole without protruding into the interior of the room. Concerning solids.

(Technical background of the invention) Conventionally, a hood that protrudes toward the interior of the room is attached to the insertion slot provided in the door, which allows various types of access to be safely carried out without anyone looking into the interior. I try to keep the mail and newspapers inside the room.

(Problems with the Background Art) However, when the hood is provided on the indoor side of the door in this way, the hood protrudes toward the indoor side, which makes the entrance narrower and is also unfavorable in terms of appearance.

(Purpose of the invention) An object of the invention is to provide a slot assembly that can be attached to a door without protruding into the room.

(Summary of the invention) This invention has an arm protrude toward the interior of the room when the opening/closing door opens when inserting mail, etc., and the insertion slot is closed via a telescoping member that expands and contracts in conjunction with this arm. It is characterized in that the closing member is made to protrude toward the indoor side only when it is inserted.

(Embodiments of the invention) Hereinafter, embodiments of the invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, a hole 2 for an insertion opening is provided at approximately the center of the door 1, passing through the door in the thickness direction. An insertion port assembly 3 according to the present invention is attached to this hole 2.
Note that the lower part of the hole 2 is inclined toward the indoor side.

The receptacle assembly 3 of the present invention includes an outer frame 4 located on the outdoor side along the circumference of the hole 2. As shown in FIG. 2, this outer frame 4 is fixed to plate members 1a, 1a extending from the door 1 toward the hole 2 via screws 5. A shaft 6 is supported above the outer frame 4, and the upper end of the opening/closing door 7 is swingably attached to the shaft 6. The opening/closing door 7 has a lower end extending below the outer frame 4 and is constantly pressed against the lower part of the outer frame 4 by a spring member 8 wound around the shaft rod 6.

Inside the hole 2 is a frame 9 having approximately the same width as the door 1.
is inserted. A locking portion 9a having a substantially triangular cross section is integrally formed on the indoor side of the frame 9, and this locking portion 9a is locked to the circumferential surface of the door 1 along the hole 2 on the indoor side. . Furthermore, the locking portion 9a of the frame body 9
A locking piece 9b protruding toward the indoor side is integrally provided nearby. Therefore, when a part of the wall surface on the indoor side of the door 1 is slightly protruded 1b into the hole 2, the frame body 9 is fitted into the hole 2 from the indoor side, and the engaging portion 9a is engaged with the wall surface on the indoor side of the door 1. Since the locking piece 9b abuts against the protrusion 1b just by stopping, the frame 9 will not come off from the hole 2.

Bent pieces 7a, 7a extending in the thickness direction of the door 1 are integrally provided at the lower sides of both sides of the opening/closing door 7, and one end of an arm 10 is rotated through a shaft 11 on each of the bending pieces 7a, 7a. It is pivoted for free movement. The other end of each arm 10 is fitted with a closing member 12 that is fitted into the frame 9 on the indoor side and closes the hole 2 from the indoor side.
It is rotatably supported via a shaft by supporting members 13, 13 fixed to the upper ends of both sides. On the other hand, on the indoor side of the inner wall surfaces on both sides of the frame body 9, one end of each of the expandable members 15, 15 is fixed to the plate members 1a, 1a protruding from the door 1, as shown in FIG. The extensible member 15 is made up of a plurality of hinges 16 connected in series in a swingable manner, and is normally contracted in a folded state by a spring material 17 attached to the shaft, and the frame body 9
Located within. The other end of this telescopic member 15 is fixed to the support member 13 of the closure member 12.

Next, the operation of the insertion port assembly 3 of the present invention will be described. That is, when the opening and closing door 7 is in the closed state, as shown by the solid lines in Figs. 1 and 2, the expandable member 1
Since the doors 5 and 15 do not extend, the closing member 12 maintains its state of being fitted into the frame 9. Therefore, in this case, the closing member 12 is positioned substantially along the wall surface on the interior side of the door 1 and does not protrude into the interior of the room.

However, when a newspaper or the like is inserted, the opening/closing door 7 is lifted around the shaft 6 against the elastic force of the spring member 8, and protrudes toward the indoor side as shown by the two-dot chain line in FIG. Therefore, a pair of arms 10, 10, one end of which is pivotally supported at the bottom of the opening/closing door 7, protrudes toward the indoor side. Therefore, the closing member 12, on which the other ends of the arms 10, 10 are pivotally supported, is connected to the telescopic member 1.
5 and 15, and as shown in the double-dashed lines in FIGS. 1 and 2 and in FIG. protrude inward.

After a newspaper or the like is inserted into the room, the opening/closing door 7 receives elastic force from the spring member 8, and the elastic member 15,
15 is subjected to an elastic force in the direction of contraction by the spring material 17, so that the opening/closing door 7 is pressed against the outer frame 4, and at the same time, the extensible members 15, 15 are contracted and folded.
The closing member 12 is fitted into the frame body 9 again. Therefore, the closing member 12 does not protrude toward the indoor side.

In the above embodiment, if the outer frame 4 is fixed to the frame 9 instead of the door 1, the outer frame 4 can be fixed to the door 1.
The insertion port assembly 3 of the present invention can be attached to the door 1 by simply fitting the frame 9 into the hole 2, omitting the work of fixing it to the plate materials 1a, 1a.

(Effects of the invention) As explained above, according to the invention, the arm protrudes indoors when the door opens, and the closing member protrudes indoors using the telescoping member that expands and contracts in conjunction with the arm. By doing so, the closing member can be made to protrude into the room from the door surface only when inserting a newspaper or the like. Therefore, the entrance connected to the door can be effectively and widely used, and since there is no protrusion on the door, the door itself has an excellent appearance. Further, since the door can be installed by simply fitting it into the door hole, the installation work is extremely simple and easy.
