A picture frame border 99 can be formed. In this embodiment, since the widths of the contacting ridges 53, 62 and the connecting contacting ridges 97, 97 are as small as about 2 mm as described above, the front and back surfaces of the door panel 27a with ventilation louvers can be , the picture frame-like edging portion 99 (FIG. 5) can be formed in a simple and neat manner.

When the door panel 27a (FIG. 4) with ventilation louvers having such a configuration is used, one side to the other side sandwiching the ventilation louver 7 can be seen through between the first and second louver blade members 5 and 6. The following special effects can be obtained while reliably preventing storage. The reason why the special effect is obtained is that the present invention is configured by the following basic configuration, that is, a combination of two members, the first rattle blade member 5 and the second rattle blade member 6, and the first , the first and second face member receiving surfaces 21 and 25 of the second ratchet blade members 5 and 6 are provided in opposite directions.

First, the ventilation efficiency of the ventilation louvers 7 can be improved. This is possible because the adoption of the basic configuration described above allows the required portion of the front side 11 of the V-shaped ridge portion 10 to be inserted into the V-shaped groove portion 8, and the front side 13 of the door panel 26 and the panel front side 13 of the door panel . When the ventilation passage 16 having the ventilation openings 39 and 40 opened at the back side 15 is formed, the first panel receiving surface 21 and the second panel receiving surface 25 are connected to the ventilation passage 16. This is because the ventilation openings 39 and 40 on the front and back sides of the front and back can be reversely arranged on the left and right sides of the openings so as not to be covered at all. As a result, the ventilation passage 16 does not have a portion that resists ventilation as in Patent Documents 1 to 3, and therefore the ventilation efficiency of the ventilation louvers 7 can be improved.

Secondly, it is possible to improve the impact resistance of the ventilation louvers 7 . This is possible because the adoption of the basic configuration described above allows the first panel receiving surfaces disposed on both sides of the ventilation opening 39 on the front side of the ventilation passage 16 and the ventilation opening 40 on the back side. 21 and the second face material receiving surface 25, the edge side portions 20, 20 can be fixed in contact with each other, thereby connecting the first and second louver blade members 5, 6 to the front and back face materials 3. , 3 can be integrated. As a result, the first and second louver blade members 5 and 6 are effectively reinforced over their entire lengths by the face members 3 and 3, thereby improving the impact resistance of the ventilation louver 7. be able to.

Since the impact resistance can be improved in this way, it is possible to extend the ventilation louvers 7 long, thereby allowing the number of the ventilation louvers 7 provided on the door panel 26 to be one or two. Even if the number is set to be small, a required amount of ventilation can be ensured according to the length of the ventilation louvers 7 .

Thirdly, the portion where the ventilation louver 7 exists can be configured to have a simple and neat appearance. This is possible because, as described in Section 2 above, the first face material receiving surface 21 and the second face material receiving surface 25 are provided with the edge side portions 20 and 20 of the face materials 3 and 3, respectively. This is because the first and second louver blade members 5 and 6 on the front and back surfaces of the door panel 26 can be prevented from being exposed by fixing the door panel 20 in the abutting state. The inclined surfaces 17 and 22 of the V-shaped groove portion 9 and the V-shaped ridge portion 10 are visually observed through the front and back ventilation openings 39 and 40 of the ventilation path 16 on the front and rear surfaces of the door panel 26. However, these are not conspicuous because they are visible recessed within the air passage 16 . In this embodiment, the portion exposed on the front and back surfaces of the door panel 26 is about the narrow width of the frame-shaped border portion 99 (FIG. 5). As a result, the portion where the ventilation louver 7 exists can be configured to have a simple and neat appearance.

Fourthly, when the door panel 27a with ventilation louvers is used, since the ventilation louvers 7 are configured to extend in the vertical direction, the ventilation is performed through the ventilation passage 16 while shielding the line of sight as described above. , light leakage from the indoor side of the door panel 26 to the corridor side (leakage of faint light such as sunshine filtering through trees) is prevented by the ventilation opening on the back side of the vertically long ventilation louver 7 (ventilation opening on the corridor side) 40 can be generated over the entire length of the As a result, for example, in hospitals, nursing homes, and nursing homes, the situation of people in the room (whether they are awake, sleeping, using the toilet, etc.) can be estimated from the corridor based on the presence or absence of the leaking light. It's easy to do.

In a conventional door panel in which the ventilation louver is provided at the lower portion of the door panel, this situation is difficult to predict because light leakage occurs only at the lower portion of the door panel. On the other hand, according to the invention of the present application, the impact resistance of the ventilation grille 7 is improved as described above. A faint light leak can be caused over the entire length of the opening 40, which makes it easier to guess the situation.

Fifthly, when the door panel 27a with ventilation rattles is used, the face members corresponding to the first and second face member receiving surfaces 21 and 25 of the first and second rattle blade members 5 and 6, respectively. When fixing the edge-side portions 20, 20 of 3, 3 in the abutting state, the tip portions 55, 61 of the edge-side portions 20, 20 are brought into contact with the abutting ridges 53, 62, thereby Positioning of the face members 3, 3 can be facilitated. In addition, the tip portions 55, 61 of the face members 3, 3 can be protected by the contacting ridges 53, 62, respectively. Furthermore, it is possible to prevent danger due to the tip portions 55 and 61 being exposed. For example, when cleaning the ventilation louver 7, the fingertip is inserted into the end portion of the ventilation passage 16 through the ventilation opening 39 on the front side and the ventilation opening 40 on the back side, and the slanted surface 17 of the ventilation louver and the When the hand is moved in the extending direction of the inclined surface 22, it is possible to prevent the hand from being scratched by the tip portion.

The abutment ridge portion 53 is provided at the base end portion of the first face material receiving surface 21, and the abutment ridge portion 62 is provided at the base end portion of the second face material receiving surface 25. Therefore, the contact ribs 53 and 62 function as reinforcing ribs, and the extended edges of the ventilation opening 39 on the front side and the ventilation opening 40 on the back side can be effectively reinforced. Accordingly, the contact ridges 53 and 62 also contribute to improving the impact resistance of the ventilation louvers 7 .
