  As shown in FIGS. 3 and 5, the door panel 14 has a structure in which a core member 28 is held between panel members 26 and 27 provided on the outdoor side and the indoor side. The panel materials 26 and 27 are comprised, for example with metal plates, such as a galvanized steel plate. The core material 28 is made of, for example, a heat insulating material such as a honeycomb structure, polystyrene foam, or urethane foam. The door panel 14 has a configuration in which a core member 28 is sandwiched between two panel members 26 and 27 and bonded and fixed with an adhesive 30, and the four peripheral ends are surrounded by a metal outer peripheral reinforcing member.

  The opening 14a is a horizontally elongated rectangular hole that penetrates the door panel 14 from the outdoor panel member 26 through the core member 28 to the indoor panel member 27. Accordingly, as shown in FIG. 3, the panel members 26 and 27 are formed with openings 26a and 27a that define the opening 14a.

  As shown in FIGS. 3 to 6, the inner periphery of the opening 14 a is covered with an upper reinforcing member 32, a lower reinforcing member 34, and left and right vertical reinforcing members 36. The upper reinforcing member 32 and the vertical reinforcing member 36 are metal shapes such as steel formed in a U-shaped cross section. The lower reinforcing member 34 is a metal shape member such as steel having an inclined surface 34a that is gradually inclined downward from the outdoor side of the opening 14a toward the indoor side, and has a substantially triangular cross section. The inclined surface 34a of the lower reinforcing member 34 serves as the bottom surface of the opening 14a, and serves as a slide for the articles thrown in from the loading port 20a. The upper reinforcing member 32, the lower reinforcing member 34, and the vertical reinforcing member 36 are fixed to the panel members 26 and 27 by screws 39 or the like.

  The inlet member 20 is attached to the outdoor side of the opening 14a, and the cover member 37 is attached to the indoor side. The cover member 37 is fixed to the outer surface of the indoor panel member 27 by screws 39 at a position avoiding a movable cover member 40 described later. A hole 37 a corresponding to the opening 14 a is formed in the cover material 37.

  The inlet member 20 is a metal plate material such as steel formed with a size larger than the opening on the outdoor side of the opening 14a (the hole 26a of the panel material 26). The inlet member 20 is attached to the outer surface of the outdoor panel member 26. In the center of the charging port member 20, a horizontal rectangular charging port 20a is formed.

  In the charging port member 20, a bearing portion 38 projects from the upper part of the inner surface of the charging port 20a. The bearing portion 38 is provided with a horizontal support shaft 38a. The lid body 22 is supported by the support shaft 38a so as to be rotatable, thereby serving as an inner opening door that opens and closes the insertion port 20a from the inside. The lid 22 is urged in a direction that always closes the insertion port 20a by a spring member 38b provided in the bearing portion 38, and retracts when pressed when an article is inserted from the insertion port 20a. Is opened (see the lid 22 shown by a two-dot chain line in FIG. 3). As shown in FIGS. 3 and 5, the lid body 22 has a surface shape protruding outward, and forms an outer surface that is substantially flush with the charging port member 20 in a state where the charging port 20 a is closed.

  The receiving box 24 is a box having an open front, and is screwed to the outer surface of the indoor panel member 27. The receiving box 24 is a box for receiving articles such as postal items put in from the insertion port 20a, and can take out the articles thrown in from an unillustrated outlet.

  As shown in FIGS. 3 and 4, the insertion port device 10 includes a movable cover member 40 that is formed of a metal such as steel and can be advanced with respect to the opening 14 a. The movable cover member 40 is accommodated in the interior of the door panel 14 at room temperature (normal time) shown in FIG. 3 and allows the article to pass through the opening 14a, while at the high temperature (heating) shown in FIG. Time) from the inside of the door panel 14 to the opening 14a to close the opening 14a.

  As shown in FIGS. 3 to 7, the movable cover member 40 includes a plate part 40 a disposed along the inner surface of the panel member 27 on the indoor side, and an obliquely upward toward the outdoor side from both sides of the lower end of the plate part 40 a. And a pair of support portions 40c, 40c that are bent upward from the tip of each connection portion 40b and are disposed along the inner surface of the panel material 26 on the outdoor side.

  The plate portion 40a is a metal plate having a dimension capable of closing the indoor opening (the hole 27a of the panel member 27) of the opening 14a. A thermally expandable member 42 is provided on the front surface (outside surface) of the plate portion 40a. The heat-expandable member 42 is a material that expands when heated, for example, a heat-foamable material mainly composed of expandable graphite. Each connecting portion 40b is a strip-shaped metal plate having an inclined surface parallel to the inclined surface 34a of the lower reinforcing member 34. A pair of support parts 40c and 40c are the strip | belt-shaped metal plates arrange | positioned so that the insertion port 20a and the cover body 22 may be straddled (refer FIG. 5).

  At the normal temperature shown in FIG. 3, most of the movable cover member 40 is housed inside the door panel 14 above the opening 14a. That is, in the movable cover member 40, the plate portion 40 a is bonded and fixed to the inner surface of the panel member 27 by the adhesive 44, and the support portion 40 c is bonded and fixed to the inner surface of the panel member 26 by the adhesive 44. Thereby, since the movable cover member 40 is retracted upward from the opening portion 14a, the article is allowed to pass through the opening portion 14a. In this state, the lower portion of the plate portion 40a and the connecting portion 40b are disposed in the opening portion 14a, but they are in a position hidden in the rotation range of the lid 22 and do not interfere with the passage of the article through the opening portion 14a. In position.

  The adhesive 44 may be applied to the entire outer surface of each of the plate part 40a and the support part 40c, or may be applied partially. The adhesive 44 is preferably not softened in the normal use state of the joinery 12 but has a property of softening only at an abnormal temperature rise due to a fire or the like (for example, 100 ° C. or more). For example, an adhesive of urethane resin is used. Use it. The same adhesive 44 and the adhesive 30 may be used.

  For example, when the joinery 12 is heated by a fire flame from the outdoor side, the movable cover member 40 falls to the opening 14a due to the softening of the adhesive 44. Thereby, at the time of high temperature shown in FIG. 4, the movable cover member 40 opens because the connecting portion 40 b lands on the inclined surface 34 a of the lower reinforcing member 34 and the plate portion 40 a closes the opening portion 14 a on the indoor side. The portion 14a is prevented from becoming a flame through-hole.

  As described above, the inlet device 10 according to the present embodiment is attached so as to cover the opening 14a formed through the door panel 14 and has the inlet 20a at a position communicating with the opening 14a. 20 and a lid body 22 that opens and closes the slot 20a of the slot member 20, and when the lid 22 is opened, from one side (outside of the door) to the other side (room) via the slot 20a. This is a device that allows the article to be introduced into the inside. The insertion port device 10 is disposed in the door panel 14 so as to be able to advance with respect to the opening portion 14a of the door panel 14, and is maintained at a position retracted from the opening portion 14a at a normal temperature while being in a high temperature state. In some cases, a movable cover member 40 that moves forward to close the opening 14a is provided.

  Thus, in the insertion port device 10, when the joinery 12 is heated to a high temperature state due to a fire or the like, the movable cover member 40 advances to the opening 14a and closes it. Therefore, even when the biasing force of the spring member 38b is weakened by heating and the lid 22 is opened by pressure due to a flame or the like, the opening 14a is reliably closed by the movable cover member 40. For this reason, it can prevent that the insertion port apparatus 10 becomes a through-hole of a flame at the time of a fire.

  In particular, the door panel 14 provided with the insertion port device 10 according to the present embodiment has a structure in which a core material 28 is bonded and fixed between two panel materials 26 and 27 using an adhesive 30. For this reason, when heated during a fire and the adhesive 30 is vaporized, combustible gas is generated, and there is a concern that the combustible gas may flow into the room. In this regard, in the insertion port device 10, since the opening 14a is reliably closed by the movable cover member 40, the inflow of the combustible gas into the room can be prevented, and the fire source and the combustible gas are separated from each other. Can be kept.

  In the insertion port device 10, a thermally expansible member 42 that expands to close the opening 14 a when heated is provided on the inner surface of the plate portion 40 a of the movable cover member 40. As a result, when the joinery 12 is heated by a fire or the like, the movable cover member 40 closes the opening 14a, and then the thermally expandable member 42 expands and fills the opening 14a, thereby closing the flame. Can be prevented more reliably.

  The movable cover member 40 is fixed to the door panel 14 with an adhesive 44 at a position above the opening 14a at normal temperature, and drops when the adhesive 44 is softened at high temperature to close the opening 14a. . This makes it possible to securely hold the movable cover member 40 in the retracted position at room temperature and smoothly move it to the advanced position in the event of a fire, while having a simple and low-cost configuration. Instead of the adhesive 44, the movable cover member 40 may be suspended and supported at a position above the opening 14a by a thermal fuse or the like that is cut by a temperature rise during a fire.

  The movable cover member 40 is provided along the inner surface of the panel member 27 on the indoor side, and has a plate portion 40a that closes the opening 14a on the indoor side of the door panel 14 when dropped. Thereby, it can prevent that the combustible gas which the adhesive agent 30 vaporized and was filled in the opening part 14a flows in into a room inner side. Moreover, by providing the thermally expandable member 42 on the outdoor surface of the plate portion 40a, the expanded thermally expandable member 42 can be smoothly filled in the opening 14a.

  The movable cover member 40 has a support portion 40c provided along the inner surface of the panel member 26 on the outdoor side opposite to the plate portion 40a. Thereby, since the position opposite to the plate portion 40a is supported by the support portion 40c, it is possible to prevent the plate portion 40a at the retracted position (see FIG. 3) or the advanced position (see FIG. 4) from rattling. Moreover, the smooth fall of the movable cover material 40 at the time of a heating can be guided by the support part 40c.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.
