  However, in the invention of Patent Document 1, in the event of a fire, the protruding carry-out part is easily exposed to flames, and when this carry-out part melts down, the shoji may drop off and the interior and the exterior may communicate. It was a problem.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door that has a window and that does not drop a shoji screen during a fire.

  The present invention includes a frame, a shoji, a cover, and an external frame, and the frame has an upper frame and a vertical frame, and the upper frame and the vertical frame are projected to the outside. The shoji is housed in the take-out part of the frame so as to be movable up and down, and the cover is attached to the upper frame and the vertical frame, and the outer peripheral side surface and outdoor side surface of each take-out part And a space portion is formed between the cover and the take-out portion, and an external frame is attached to the outdoor side of the cover.

  According to the present invention, since the outer peripheral side surface and the outdoor side surface of the take-out portion protruding to the outdoor side are covered with the cover, the take-out portion is not directly exposed to the flame. In addition, since a space is formed between the cover and the take-out part, the heat of the flame is not easily transmitted to the take-out part. Furthermore, since the external frame is attached to the outdoor side of the cover, the heat of the flame is less likely to be transmitted to the take-out part. As a result, the take-out part is prevented from melting in the event of a fire, and the shoji does not fall out and the indoors and the outdoors are not communicated.

It is a longitudinal cross-sectional view of the upper frame part of a door. It is a cross-sectional view of the vertical frame part of a door. It is a longitudinal cross-sectional view of a door. It is a cross-sectional view of a door. (A) is a front view on the outdoor side of the door (the screen door frame is not shown), and (b) is a front view on the indoor side of the door.

  Hereinafter, embodiments of the door of the present invention will be described with reference to the drawings.

As shown in FIGS. 3 to 5, the door is a frame formed by a four-round frame of an upper frame 11, a lower frame 12, and left and right vertical frames 13. The body 1 is comprised, and the outer shoji 2a and the inner shoji 2b are inserted in the inner peripheral side. The left side is the door end side, the right side is the hanging side, and the right vertical frame 13 is attached to the housing by a hinge 10. The hinges 10 are arranged at equal intervals at the vertical center of the vertical frame 13 and at three locations above and below it. Each of the external shoji 2a and the inner shoji 2b has an upper collar 21a, 21b, a lower collar 22a, 22b, and left and right vertical collars 23a, 23b. The upper collar 21a, 21b and the lower collar 22a, 22b The vertical rods 23a and 23b are attached to the left and right ends, and are assembled into four rounds, and the glass panels 24a and 24b are accommodated on the inner peripheral side thereof. At the time of closing, the outer shoji 2a is on the upper side and the inner shoji 2b is on the lower side. The crescent lock 20 is provided on the upper side of the upper collar 21b of the inner limb 2b and can be locked when closed. In addition, each frame and each collar are made of an aluminum member on the outdoor side and a resin member on the indoor side.

  More specifically, as shown in FIG. 2, the outer peripheral side 13b extending to the outdoor side and the outer peripheral side 13b of the left and right vertical frames 13 are extended to the inner peripheral side from the outdoor side of the outer peripheral side 13b. A take-out portion 13a composed of the outdoor side surface 13c is formed, and the expected width of the inner peripheral side end portion of the vertical frame 13 is widened by the take-out portion 13a. Two guide grooves 14a and 14b extending vertically are formed side by side on the inner peripheral side of the vertical frame 13 (and the take-out portion 13a). The guide grooves 14a and 14b have a substantially U-shaped cross section, and the guide groove 14a on the outdoor side is formed in the take-out portion 13a. The left and right ends (vertical rods 23a) of the outer obstacle 2a are accommodated in the outdoor guide groove 14a, and the left and right ends (vertical rods 23b) of the inner obstacle 2b are accommodated in the indoor guide groove 14b. And the inner shoji 2b is movable up and down. The outer shoji 2a and the inner shoji 2b are connected by a wire 30 so as to be interlocked. When one shoji is moved, the other shoji moves in the opposite direction by the same distance. Further, as shown in FIG. 1, a take-out portion 11 a composed of an outer peripheral side surface 11 b and an outdoor side surface 11 c is formed on the outdoor side of the inner peripheral side (lower side) end of the upper frame 11, similarly to the vertical frame 13. In the closed state of the external shoji 2a, the upper end (upper collar 21a) of the external shoji 2a is stored. Further, an extended piece 12 a extending outward is formed on the outdoor side of the inner peripheral side (upper) end of the lower frame 12.

  As shown in FIGS. 1 and 2, the cover 5 is attached to the take-out portions 11 a and 13 a formed in the upper frame 11 and the vertical frame 13. The cover 5 attached to the upper frame 11 has a prospective surface 51 and a finding surface 52 extending from the outdoor side end of the prospective surface 51 to the inner peripheral side (lower side). A substantially U-shaped engaging portion 53 that opens toward the outdoor side is formed at the indoor side end of the viewing surface 51, and a contact piece 54 that extends toward the indoor side is formed at the lower end of the finding surface 52. It is. Further, an inclined piece 55 is formed at the lower end of the finding surface 52 so as to extend downward in the outdoor side. The upper frame 11 is formed with a groove-like engaged portion 11d adjacent to the outer peripheral side surface 11b of the take-out portion 11a, and the engaging portion 53 of the cover 5 is fitted into the engaged portion 11d to be engaged. The portion 53 is fixed to the outer peripheral side surface 11b with screws. At this time, the tip of the contact piece 54 is in contact with the outdoor side surface 11c of the take-out portion 11a. Moreover, the engaging part 53 has covered the lower end part of the outdoor side surface of the upper frame 11, and the indoor side edge part (base part of the taking-out part 11a) of the outer peripheral side surface 11b of the taking-out part 11a. The cover 5 attached to the upper frame 11 as described above covers the outer peripheral side surface 11b and the outdoor side surface 11c of the take-out portion 11a of the upper frame 11, and the expected surface 51 of the cover 5 and the outer peripheral side surface of the take-out portion 11a. A space portion 5a is formed between the surface 11b and the finding surface 52 of the cover 5 and the outdoor side surface 11c of the take-out portion 11a. And the heating foam material 4 is attached to the inner peripheral side surface (lower surface) of the prospective surface 51 of the cover 5. The heated foam material 4 foams when heated and expands in the thickness direction (perpendicular to the mounting surface). The cover 5 attached to the vertical frame 13 also has a prospective surface 51 and a finding surface 52 extending from the outdoor side end of the prospective surface 51 to the inner peripheral side. A substantially L-shaped engaging portion 53 protruding toward the indoor side is formed at the indoor side end of the viewing surface 51, and a contact piece extending toward the indoor side at the inner peripheral side end of the finding surface 52 54 is formed. Further, a hollow portion 56 is formed on the inner peripheral side of the prospective surface 51. The vertical frame 13 is formed with a groove-like engaged portion 13d adjacent to the outer peripheral side surface 13b of the take-out portion 13a. The engaging portion 53 of the cover 5 is fitted into the engaged portion 13d, and the hollow portion The inner peripheral side wall surface of 56 is fixed by screwing to the outer peripheral side surface 13b. At this time, the tip of the contact piece 54 is in contact with the outdoor side surface 13c of the take-out portion 13a. Thus, the cover 5 attached to the vertical frame 13 covers the outer peripheral side surface 13b and the outdoor side surface 13c of the take-out portion 13a of the vertical frame 13, and the outdoor side of the finding surface 52 of the cover 5 and the take-out portion 13a. A space 5a is formed between the side surfaces 13c.

  Further, a screen door frame (outer frame) 6 is attached to the outdoor side surface of the cover 5. The screen door frame body 6 prevents insects from entering when the raising and lowering windows are opened. The screen door frame body 6 includes a screen door upper frame 61, a screen door lower frame 62, and a screen door vertical frame 63, and a net material 64 is stretched. is there. More specifically, an attachment member 65 having an attachment piece 66 extending upward is screwed to the inclined piece 55 of the cover 5 attached to the upper frame 11, and the screen door upper frame 61 is screwed to the attachment piece 66. Further, a hooking member 67 having a hooking piece 68 extending in the outdoor direction is screwed to the finding surface 52 of the cover 5 attached to the vertical frame 13, and the hooking piece 68 is formed on the inner side surface of the screen door vertical frame 63. The screen door vertical frame 63 is hooked by being inserted into the hole. The screen door lower frame 62 is in contact with the tip of the extended piece 12 a of the lower frame 12.

  According to the door configured as described above, the outer peripheral side surfaces 11b and 13b and the outdoor side surfaces 11c and 13c of the take-out portions 11a and 13a projecting to the outdoor side are covered with the cover 5, so that the take-out portions 11a and 13a are There is no direct flame exposure. Further, a space portion 5a is formed between the cover 5 and the take-out portions 11a and 13a (the outer peripheral side surface 13b of the take-out portion 13a of the vertical frame 13 is in contact with the cover 5, but Since the hollow portion 56 of the cover 5 is located, the prospective surface 51 of the cover 5 and the outer peripheral side surface 13b of the take-out portion 13a are separated from each other), and the heat of the flame is hardly transmitted to the take-out portions 11a and 13a. Furthermore, since the screen door frame 6 is attached to the outside of the cover 5, the heat of the flame is less likely to be transmitted to the take-out portions 11a and 13a. In particular, in the upper cover 5, the root portion of the carry-out portion 11 a that is most protected from the flame heat is removed by the engaging portion 53 of the cover 5 (because the entire carry-out portion 11 a falls off when the root portion melts). Cover and protect. And since the heating foam material 4 is attached to the inner peripheral side surface of the prospective surface 51 of the cover 5, it foams at the time of a fire, and covers the outer peripheral side surface 11b of the taking-out part 11a, and protects from a flame heat. Thus, the carry-out portions 11a and 13a are prevented from melting in the event of a fire, and the external shoji 2a is not dropped and the interior and the exterior are not communicated. Further, when the screen door frame 6 is directly attached to the take-out portions 11 a and 13 a, the load of the screen door frame 6 is concentrated on the tips of the take-out portions 11 a and 13 a, but when the screen door frame 6 is attached to the cover 5. The load of the screen door frame 6 is dispersed throughout the take-out portions 11a and 13a through the cover 5, and deformation of the take-out portions 11a and 13a is suppressed. Furthermore, the cover 5 covers the outer peripheral side surfaces 11b and 13b and the outdoor side surfaces 11c and 13c of the take-out portions 11a and 13a, so that the cover 5 can be seen in place of the take-out portions 11a and 13a as compared with the conventional door. Since the appearance is substantially the same as the conventional one, the design of the door is not impaired.

  As shown in FIG. 3, a standing piece 17 extending upward is formed on the indoor side (aluminum member portion) of the inner peripheral side (upper) end of the lower frame 12. A tight material holder 15 is formed at the upper end. The tight material holder 15 has a groove shape that opens upward, and is fitted with a tight material 16. The tight material 16 is in contact with the indoor side portion of the lower end (lower collar 22b) of the inner impingement 2b in the closed state of the inner impingement 2b to ensure airtightness and water tightness. And the lower collar 22b of the inner impeller 2b has the edge material 3. The edge member 3 has a drooping piece 31 that is substantially L-shaped and extends downward, and is screwed to the lower surface of the lower collar 22b. The drooping piece 31 is located at the outdoor side end of the lower collar 22b, and faces the outdoor side surface of the tight material holder 15 of the lower frame 12 in the closed state of the inner shroud 2b. Furthermore, the left and right width of the edge member 3 is longer than the left and right width of the lower rod 22 b, and the left and right ends of the edge member 3 are sandwiched in the guide grooves 14 b of the vertical frame 13. Moreover, the heating foam 4 is attached to the indoor side surface of the hanging piece 31. On the other hand, the heating foam material 4 is also attached to the outdoor side of the standing piece 17 of the lower frame 12. The heated foam material 4 is foamed by being heated and expands in the thickness direction (perpendicular to the mounting surface). The heated foam material 4 is foamed in the event of a fire and has a gap between the lower frame 12 and the lower rod 22b. Block. In this way, since the left and right ends of the edge member 3 attached to the lower collar 22b of the inner impeller 2b are sandwiched in the guide groove 14b of the vertical frame 13, the vertical frame 13 and the edge material 3 (lower 22b), there is no gap, and the drooping piece 31 of the edge member 3 protects the tight member 16 from flame heat in the event of a fire. Further, the heating foam 4 is attached to the edge material 3 that is longer to the left and right than the lower collar 22b of the inner impeller 2b, and foamed in the event of a fire in combination with the heating foam 4 attached to the standing piece 17 of the lower frame 12. Covers the entire length of the lower end portion of the inner shoji 2b. Thus, it is possible to reliably prevent the indoor and outdoor communication at the lower end portion of the inner impingement 2b during a fire.

  Moreover, the panel support material 7 made of iron and having a U-shaped cross-section is attached to the entire circumference of the glass panels 24a and 24b of the external shoji 2a and the internal shoji 2b. This prevents the glass panels 24a and 24b from coming off when the sash is exposed to flame heat and the upper ridges 21a and 21b, the lower ridges 22a and 22b and the vertical ridges 23a and 23b are melted, and maintains the airtightness of the raised and lowered windows. Is to do.

  Furthermore, the reinforcing material 8 made of iron and having a U-shaped cross section is inserted into the hollow portion of each of the collars (upper collars 21a, 21b, lower collars 22a, 22b and longitudinal collars 23a, 23b) of the external shoji 2a and the inner shoji 2b. (Only the reinforcing member 8 of the upper collar 21a of the outer shoji 2a has an L-shaped cross section). The reinforcing member 8 extends over the entire length of each ridge and is screwed from the outside. This is to suppress the elongation of each heel when the sash is exposed to flame heat.

  Besides the inner side of the upper cover 5 and the lower collar 22b portion of the inner shoji 2b, the inner side of each guide groove 14a, 14b, the inner side of the take-out portion 11a of the upper frame 11, and the vertical collar 23a of each shoji 2a, 2b. , 23b, the inside of the panel support member 7, the indoor side surface of the lower collar 22a of the outer shoji 2a, and the outdoor side surface of the upper collar 21b of the inner shoji 2b, the heating foam material 4 is attached, and there is a gap in the event of a fire. Block it.

  The present invention is not limited to the above embodiment. For example, the external shoji and the internal shoji can be opened and closed independently, or the external shoji can be fixed. In addition to the screen door frame, the external frame may have a rectangular frame shape, such as a grid with a plurality of crosspieces, and various types for the purpose of preventing insect entry, blindfolding, crime prevention, etc. Including
