[0022] The screen bottom frame 52 has a mohair attachment groove 52f on the indoor side of the inner peripheral visible wall 52c, and mohair 522 extending toward the inside of the room is attached. The screen bottom frame 52 has tapping holes 52g, 52g on the indoor side of the observation wall 52a for connecting to the screen vertical frame body 531 of the screen vertical frame 53.

[0023] As shown in FIG. 9(a), the mesh body 55 constituting the screen door device 5 has a mesh material 551 and mounting rubbers 552 attached by welding, adhesion or the like along the left and right edges of the mesh material 551. The mounting rubber 552 has a visible wall 552a, and an inner circumferential side locking piece 552b and an outer circumferential side locking piece 552c extending from the visible wall 552a to the outside of the room.

[0024] The mounting rubber 552 is provided with a net mounting portion 552d extending further inward than the inner circumferential engaging piece 552b on the inner circumferential side of the visible wall 552a, and the net material 551 is attached to the net mounting portion 552d by welding, adhesion or the like. The mounting rubber 552 is provided with a handle portion 552e on the outer periphery of the visible wall 552a, the handle portion 552e extending outwardly beyond the outer periphery locking piece 552c. The mounting rubber 552 has an inner side locking portion 552f and an outer side locking portion 552g which extend away from each other at the outdoor end of the inner side locking piece 552b and the outer side locking piece 552c, and as shown in Figure 9 (c), the extension amount x1 of the outer side locking portion 552g is formed larger than the extension amount x2 of the inner side locking portion 552f.

[0025] (Installation procedure of the screen door device according to the embodiment) The procedure for installing the screen door device 5 will now be described. First, the left and right vertical screen door frames 53, 53's vertical screen door frame bodies 531, 531, the upper screen door frame 51 and the lower screen door frame 52 are assembled into a frame. For example, as shown in Figures 7 and 8, the left and right end faces of the upper screen frame 51 and the lower screen frame 52 are abutted against the inner periphery projecting walls 531b of the vertical screen frame bodies 531, 531 of the left and right vertical screen frames 53, 53, and the framework is formed by fastening them with screws via tapping holes 51g, 52g.

[0026] Here, the left and right vertical screen door frame bodies 531, 531 have grooves 531c cut out at the upper and lower portions. Specifically, with the upper screen frame 51 and the lower screen frame 52 attached to the inner projecting wall 531b of the vertical screen frame body 531, the inner side wall 531e and the outer side wall 531f which form the groove portion 531c are cut out at a position outer than the mohair 512, 522 provided in the mohair mounting grooves 51f, 52f of the upper screen frame 51 and the lower screen frame 52. In the embodiment shown in Figures 7 and 8, the vertical screen door frame body 531 has a groove portion 531c cut into the outer periphery at a height position approximately the same as the outer periphery ends of the inner peripheral side visible walls 51c, 52c of the upper screen door frame 51 and the lower screen door frame 52.

[0027] Next, the screen body 55 is attached to the frame in which the screen vertical frame bodies 531, 531, the screen upper frame 51, and the screen lower frame 52 are assembled into a frame. For example, as shown in Figures 7, 8 and 9(b), the mesh body 55 is attached to the frame by fitting the inner peripheral locking piece 552b and the outer peripheral locking piece 552c of the mounting rubber 552 attached along the left and right edges of the mesh material 551 into the grooves 531c, 531c of the left and right vertical screen door frame bodies 531, 531. At this time, the upper and lower ends of the mesh body 55 are attached so that they are positioned outer than the mohair 512, 522 provided on the upper screen frame 51 and the lower screen frame 52, for example, at a position approximately the same as the outer peripheral ends of the inner peripheral visible walls 51c, 52c of the upper screen frame 51 and the lower screen frame 52.

[0028] The frame on which the mesh body 55 is stretched has the mohair 512, 522 attached to the upper and lower screen frames 51, 52 abutting against the upper and lower indoor sides of the mesh body 55 attached to the left and right vertical screen frame bodies 531, 531, thereby preventing insects and other insects from entering between the upper and lower screen frames 51, 52 and the mesh body 55. Furthermore, by attaching the upper and lower ends of the mesh body 55 so that they are positioned closer to the outer periphery than the mohair 512, 522 provided on the upper screen frame 51 and the lower screen frame 52, the upper and lower ends of the mesh body 55 can maintain abutment against the mohair 512, 522 even if the mesh body 55 shrinks slightly in the vertical direction.

[0029] Next, the frame to which the mesh body 55 is attached is fixed to the exterior side surface of the door body 1. For example, as shown in Figures 3 and 4, the mounting rubber 552 of the mesh body 55 attached to the vertical screen frame main body 531 is positioned on the inner periphery of the left and right vertical frames 23, 23 of the ventilation window 2, and the mohair 512, 522 provided on the upper screen frame 51 and the lower screen frame 52 are positioned on the outer side of the door body 1, and the visible wall 531a of the vertical screen frame main body 531 is fixed to the door body 1 with screws b23.

[0030] Finally, the vertical screen door cover body 532 is fixed from the outside of the room to the vertical screen door frame bodies 531, 531 attached to the door body 1, completing the installation. For example, as shown in Figures 4(b) and 5, the inner peripheral engaged portion 532c of the vertical screen cover body 532 is engaged with the engaging portion 531d of the vertical screen frame body 531, and the outer peripheral locking portion 532d is locked to the engaging part 1d attached to the exterior side of the door body 1, thereby fixing the vertical screen frame body 531 to the exterior side surface of the door body 1 so as to cover it from the outside. The procedure for installing the screen door device 5 has been explained above.

[0031] (Effect of the fire prevention equipment of the embodiment) The opening device of this embodiment has a screen device 5 which is configured by stretching a mesh body 55 around the inner periphery of a screen frame 50 which is made up of an upper screen frame 51, a lower screen frame 52 and left and right vertical screen frames 53, 53 all around, and which is attached to the outside of the door body 1. This allows a screen to be easily installed in relation to the ventilation section provided in the door body 1, thereby improving ease of installation and maintenance.

[0032] In the opening device of this embodiment, a mesh body 55 is attached to the left and right vertical screen frames 53, 53 of the screen device 5 using mounting rubbers 552, and the top and bottom of the mesh body 55 are abutted against mohair 512, 522 provided on the upper screen frame 51 and the lower screen frame 52, thereby sealing the gap between the screen frame 50 and the mesh body 55.This prevents rainwater and the like from accumulating at the attachment portion of the mesh body 55 to the lower screen frame 52, thereby suppressing deterioration due to freezing and the accumulation of debris and improving durability.

[0033] In the opening device of this embodiment, the mesh body 55 can be attached by fitting the mounting rubber 552 into the groove 531c of the left and right vertical screen frames 53, 53, making it easy to install.In addition, by allowing the mounting rubber 552 to follow the longitudinal expansion of the mesh body 55, which is long vertically, the occurrence of wrinkles and the like in the corners can be suppressed, thereby improving durability.

[0034] In the opening device of this embodiment, the extension amount x1 of the outer peripheral locking portion 552g of the mounting rubber 552 which is fitted into the groove portion 531c of the left and right vertical screen door frames 53, 53 is set to be greater than the extension amount x2 of the inner peripheral locking portion 552f, thereby increasing the engagement amount of the outer peripheral locking portion 552g with the groove portion 531c. Therefore, as shown in Figure 9(d), when external pressure due to wind or the like is applied to the mesh body 55, the outer peripheral locking portion 552g of the mounting rubber 552 can be engaged more deeply with the outer peripheral locking portion 531h against the moment centered on the abutment point between the inner peripheral locking piece 552b and the locking portion 531g of the groove portion 531c, thereby preventing the mesh body 55 from coming off. In addition, since the mounting rubber 552 has a handle portion 552e provided on the outer periphery of the outer periphery locking portion 552g, the lock of the outer periphery locking portion 552g, which has a large engagement amount, can be directly released by pinching the handle portion 552e and pulling it toward the inside of the room, thereby facilitating replacement of the mounting rubber 552 and improving maintainability.

[0035] (Other embodiments) The opening device of the present invention is not limited to an air intake window provided in a front door, and the type of fitting is not limited as long as it is an opening device equipped with a screen door on the outside of the room. In addition, it goes without saying that the above embodiments do not limit the invention described in the claims, but are treated as examples. [Explanation of symbols]
