  The engagement groove portion 60 is a portion engaged with the vertical rail 37 provided on the vertical frame 35 when the shoji 40 is closed. The vertical rail 37 is a metal (made of aluminum) extrusion-formed member provided on the vertical frame 35 so as to protrude from the vertical frame 35 toward the inner side (central side) in the left and right direction. Is provided from one end to the other end (continuously in the longitudinal direction of the vertical frame 35). Then, when the shoji 40 is closed, the vertical rail 37 enters the groove of the engagement groove 60, and the tip of the vertical rail 37 in the left and right direction is attached to the groove bottom 60c of the engagement groove 60 described later. It is in contact with the piece 72.

  The engaging groove portion 60 has a U-shape in cross section, and two groove side surfaces facing each other (a groove side surface on the indoor side is referred to as an indoor side groove side surface 60a and a groove side on the outdoor side is referred to as an outdoor side groove side surface 60b); And a groove bottom surface 60c. The groove side surface is a surface along the lateral direction in the cross section, and the groove bottom surface 60c is a surface along the viewing direction in the cross section.

  In the groove of the engagement groove portion 60, three kinds of members described below, that is, the light shielding metal fitting 70, the attracting piece 72, and the shoji opening prevention metal fitting 80 are attached.

  The flame shield 70 is a non-combustible or non-combustible thin plate, and has a function of blocking a flame in the event of a fire. The flameproof fitting 70 is a long member made of metal (stainless steel), and extends from one end to the other end in the vertical direction of the engagement groove 60 (toe 56) (engagement groove 60 (Continuously in the longitudinal direction of the door tip 56)).

  The flame shield 70 has an L shape in the cross section, and a portion along the viewing direction in the cross section (referred to as the first flame shield portion 70a) and a portion along the lateral direction in the cross section (Referred to as two light shielding metal fitting portions 70 b)). The first light shield fitting portion 70a covers the groove bottom surface 60c, and the second light shield fitting portion 70b is attached to the engagement groove portion 60 so as to cover the outer side groove side surface 60b. In other words, the light shielding metal fitting 70 contacts so that the first light shielding metal fitting portion 70a overlaps with the groove bottom surface 60c, and the second light shielding metal fitting portion 70b contacts with the outdoor side groove side surface 60b. It is provided.

  And the screw hole is provided in the first light shielding metal part 70a of the light shielding metal fitting 70, and the light shielding metal fitting 70 (the first light shielding metal fitting part 70a) is fixed to the reinforcing material 78 described later by the screw 90. There is.

  The pull-in piece 72 is a member provided to improve the air tightness performance and the waterproof performance, and when the shoji 40 is closed, it engages with the vertical rail 37 and the inside of the shoji 40 in the prospect direction (the shoji 40 It has a function of drawing the indoor side if it is the outer case 40a, and the outdoor side if it is the inner case 40b. The attraction piece 72 is composed of a metal (aluminum) aluminum block 74 and a synthetic resin resin cover 76. That is, the pulling piece 72 is one in which the aluminum block 74 is covered by the resin cover 76.

  In the present embodiment, a plurality of, for example, four pull-in pieces 72 are provided, and each pull-in piece 72 is at a predetermined interval at different positions in the vertical direction of the engagement groove 60 (toe 56). It is attached.

  The pull-in piece 72 includes a pull-in piece main body 72 a and a protrusion 72 b protruding from the pull-in piece main body 72 a in the left-right direction toward the vertical frame 35. A screw hole is provided in the pulling piece main body 72a, and the pulling piece 72 (pulling piece main body 72a) is fixed to a reinforcing material 78 described later by a screw 90.

  The projecting portion 72 b is located indoors more than the vertical rail 37 in the view direction when the shoji 40 is closed. And the protrusion part 72b overlaps with the vertical rail 37 in the direction of anticipation in the state located indoors rather than the vertical rail 37 (it overlaps). In addition, the projecting portion 72b is provided with a tapered portion, and this tapered portion is engaged with the tapered portion of the vertical rail 37 so that the pulling function of the projecting portion 72b is exhibited.

  In addition to the attraction function, the attraction piece 72 according to the present embodiment has a function to prevent the opening of the shoji 40 (toe door 56) in the event of a fire and the passage of flames. There is. That is, when a fire occurs, shoji 40 (toe hook 56) assumes the heating surface side (in the present embodiment, it is assumed that a fire will occur on the outdoor side) in the prospect direction, so the heating surface side is a room Will be pulled to the outside). That is, a force from the indoor side to the outdoor side acts on the shoji 40 (toe hook 56) in the expected direction.

  On the other hand, in the present embodiment, with the protrusion 72b of the pull-in piece 72 attached to the door tip 56 positioned indoors more than the vertical rail 37, the longitudinal rail 37 and the projection in the perspective direction Since it wraps, even if the force is applied to the shoji 40 (toe hook 56) to move, the projection 72b of the pulling piece 72 is blocked against the vertical rail 37 and blocked. Therefore, in the case of a fire, the pull-in piece 72 (protrusion part 72b) plays a role of preventing the shoji 40 (toe door 56) from opening to cause a flame passage.

  Furthermore, in the pull-in piece 72 according to the present embodiment, the projecting portion 72 b is configured of the resin cover 76 and the aluminum block 74, and not only the resin cover 76 but also the aluminum block 74 in the direction of prospect It is overlapping. That is, since the aluminum block 74 has an overlapping portion (that is, the projecting portion 72b) overlapping with the vertical rail in the expected direction, the aluminum block 74 is melted even if the resin cover 76 is exposed to the flame and melted in the fire. Is blocked against the vertical rail 37, and the function of preventing the shoji 40 (toe door 56) from opening and causing a flame path is exhibited.

  The shoji opening prevention fitting 80 is a thin plate-like fitting provided separately from the pull-in piece 72, and like the pull-in piece 72, the shoji 40 (door tip 56) opens in the event of a fire and the flame passage is It has a function to prevent it from occurring.

  However, unlike the pull-in piece 72, only one shoji opening prevention fitting 80 is provided. Also, unlike the pull-in piece 72, it is a dedicated member for preventing the opening of the shoji that functions only when a fire occurs.

  The shoji opening prevention fitting 80 is a long member made of metal (stainless steel), and the length in the vertical direction is longer than the length in the vertical direction of the attracting piece 72 (aluminum block 74). And 8% or more and 12% or less of the length of the door tip collar 56 in the vertical direction. In addition, for the shoji opening prevention fitting 80, stainless steel thicker than the light shielding fitting 70 is used (0.5 mm for the flame prevention attachment 70 compared to 1.5 mm for the shiso opening prevention fitting 80).

  In addition, the shoji opening prevention metal fitting 80 is attached to the lower part of the engagement groove 60 (toe 56). The shoji opening prevention fitting 80 is L-shaped or U-shaped (in the present embodiment, L-shaped) in the cross section, and a portion along the prospecting direction in the cross section (referred to as a first prevention fitting portion 80a And a portion along the lateral direction in the cross section (referred to as a second prevention fitting portion 80b). Then, the first prevention fitting portion 80a engages so that the first light shielding fitting portion 70a covering the groove bottom surface 60c is covered, and the second prevention fitting portion 80b covers the indoor side groove side surface 60a. The groove 60 is attached. In other words, the shoji opening prevention fitting 80 is in contact when the first prevention fitting portion 80a is in contact with the first light shielding fitting portion 70a and the second prevention fitting portion 80b is in contact with the indoor groove side surface 60a. It is provided to do.

  And the screw hole is provided in the 1st prevention metal fitting part 80a, and the shoji opening prevention metal fitting 80 (1st prevention metal fitting part 80a) is being fixed to the reinforcing material 78 mentioned later by the screw 90.

  The second prevention fitting portion 80b is located indoors more than the vertical rail 37 in the direction of sight when the shoji 40 is closed. Then, the second prevention fitting portion 80b overlaps (overlaps) with the vertical rail 37 in the view direction in a state where the second prevention metal fitting portion 80b is positioned indoors more than the vertical rail 37. That is, the second prevention fitting portion 80b corresponds to the overlapping portion A overlapping with the vertical rail 37 in the expected direction. In addition, about the shoji opening prevention metal fitting 80, since stainless steel thicker than the light shielding metal fitting 70 is used, the thickness (1.5 mm) of the overlapping portion A is also thicker than the thickness of the light shielding metal fitting 70 (0.5 mm) It has become.

  As described above, when a fire occurs, the shoji 40 (toe door 56) is heated side (in the present embodiment, it is assumed that a fire will occur outside the room) in the prospect direction, so the heating side is considered Is pulled to the outdoor side). That is, a force from the indoor side to the outdoor side acts on the shoji 40 (toe hook 56) in the expected direction.

  On the other hand, in a state where the second prevention fitting portion 80b of the shoji opening prevention fitting 80 attached to the door tip 56 is positioned indoors more than the vertical rail 37, it overlaps with the vertical rail 37 in the expected direction Therefore, even if the force is applied to the shoji 40 (toe door 56) to move it, the second prevention metal fitting portion 80b of the method opens the vertical rail 37 and blocks. Therefore, at the time of a fire, the shoji opening prevention fitting 80 (the second prevention fitting part 80b) plays a role of preventing the shoji 40 (toe door 56) from opening and the passage of the flame being generated.

  In addition, a heat-foamable material is attached to the light shielding fitting 70 and the shoji opening preventing fitting 80. In the following, the heat-foamable material provided on the light-insulation metal fitting 70 is prevented from the heat-foamable material on the light-insulation metal fitting side (corresponding to the heat-foamable material for the light-insulation metal fitting) It calls it the metal fitting side heating foam material 85 (equivalent to the heating foam material of a shoji opening prevention metal fitting), respectively. This heated foam expands when exposed to a flame during a fire, and its volume increases. And by this, a crevice can be filled up and the course of a flame can be closed.

  The flameproofing fitting-side heating foam material 84 is attached to the second flameproofing fitting portion 70b, and the prevention fitting side heating foam material 85 is adhered to the second prevention fitting part 80b. The flame shield fitting side heating foam material 84 is provided from one end to the other end in the vertical direction of the flame shield fitting 70 (continuously in the longitudinal direction of the flame shield fitting 70), and the prevention fitting side heating foam material 85 Is provided so as to extend from one end to the other end in the up-down direction of the shoji opening prevention fitting 80 (continuously in the longitudinal direction of the shoji opening prevention fitting 80). Therefore, the flameproof metal fitting side heating foam material 84 and the prevention metal fitting side heating foam material 85 are in a state where the vertical rail 37 is positioned between the two heating foam materials (as both heating foam materials sandwich the vertical rail 37) , Are facing each other in the perspective direction. In other words, the light shielding fitting side heating foam material 84 faces the vertical rail 37 in the view direction, and the prevention fitting side heating foam material 85 also faces the vertical rail 37 in the view direction. In addition, at the time of a non-fire (at the time of non-expansion of a heating foaming material), the vertical rail 37 is not in contact with the flame shielding fitting side heating foaming material 84 (prevention metal fitting side heating foaming material 85).

  Further, the rail side heating foam material 86 (corresponding to the heating foam material of the rail) is also provided in the vertical rail 37, and the rail side heating foam material 86 is the side of the prevention fitting side heating foam material 85 and the light shielding fitting side.

=== Regarding the effectiveness of the sliding window 10 according to the present embodiment ===
As described above, in the present embodiment, the fold window 10 is provided slidably with respect to the frame 20 provided with the upper frame 30, the lower frame 32, and the vertical frames 35 on the left and right sides. And the lower frame 54 and the left and right hooks (toe hook 56 and the combined hook 58), and at least one of the vertical frames 35 of the left and right vertical frames 35 is formed on the back hook 56 The vertical rail 37 engaged with the engagement groove 60 is provided. Then, the engagement groove portion 60 is attached with a shods opening prevention metal fitting 80 having an L-shaped cross section or a U-shaped cross section and having a overlapping portion A overlapping the vertical rail 37 in the direction of view. Therefore, it becomes possible to realize the sliding window 10 capable of preventing the door tip 56 from opening when a fire occurs and the passage of the flame being generated.

  In the conventional sliding window 10, when a fire occurs, the shoji 40 is pulled toward the heating surface in the perspective direction, and the engagement groove 60 formed in the door tip 56 of the shoji 40 is disengaged from the vertical rail 37 ( There was a case to get out. In such a case, there is a problem that a flame passage (a through hole) is generated by opening the door tip 56.

  On the other hand, in the present embodiment, a shods opening prevention metal fitting 80 having an L-shaped or U-shaped cross section and overlapping portions A overlapping the vertical rails 37 in the direction of prospect is attached to the engaging groove 60 Since the force to be pulled toward the heating surface side is applied to the shoji 40 (the toe hook 56) to move the shoji 40, the shoji opening prevention metal fitting 80 is blocked against the vertical rail 37 and blocked. Therefore, since the shoji opening prevention metal fitting 80 plays a role of preventing the shoji 40 (toe door 56) from opening and causing a flame passage at the time of fire, the toe hook 56 is used when the fire occurs. It is possible to realize a sliding window 10 that can be opened to prevent the passage of flames from occurring.

  Further, in the present embodiment, a pull-in piece 72 composed of an aluminum block 74 and a resin cover 76 is attached to the engagement groove portion 60, and the aluminum block 74 overlaps the vertical rail 37 in the view direction. It was decided to have an overlapping portion.

  Therefore, not only the shoji opening prevention metal fitting 80 but also the pulling piece 72 has a function to prevent the door tip weir 56 from opening when the overlapping portion hits the vertical rail 37 at the time of fire, and a flame passage is generated. It is possible to Therefore, when a fire occurs, it is possible to more appropriately prevent the door tip 56 from being opened and the passage of the flame being generated.

  Further, in the present embodiment, the length in the vertical direction of the shoji opening prevention metal fitting 80 is longer than the length in the vertical direction of the aluminum block 74.

  Since the pull-in piece 72 is a conventional part provided with a pull-in function, it is difficult to increase the length in the vertical direction even though the conventional part can be provided with the function of preventing the opening of an obstacle. In the present embodiment, in order to compensate for this, the length of the shods opening prevention metal fitting 80, which is a dedicated member for preventing shods opening, is made longer than the length of the attracting piece 72 (aluminum block 74). Therefore, the special member can be provided with a great ability to prevent the opening of the door, and when the fire occurs, it becomes possible to more appropriately prevent the door tip 56 from opening and the passage of the flame being generated.

  Further, in the present embodiment, the length in the vertical direction of the shoji opening prevention metal fitting 80 is 8% or more and 12% or less of the length in the vertical direction of the door tip 56.

  If the length in the vertical direction of the shoji opening prevention metal fitting 80 is smaller than 8% of the length in the vertical direction of the door tip 56, the shoji opening prevention function does not work sufficiently, while on the other hand, if it is longer than 12% The improvement of the effect of preventing the opening of the window is not expected so much, and the cost merit is reduced. Therefore, in such a case, it is possible to realize the unobstructed opening prevention fitting 80 in which the unobstructed opening function works properly at low cost.

  Further, in the present embodiment, the light shielding metal fitting 70 which is continuous in the longitudinal direction of the door tip 56 is attached to the engagement groove 60.

  Therefore, the flame can be appropriately blocked, and the fire protection function is further improved.

  Further, in the present embodiment, the thickness of the overlapping portion A of the shoji opening prevention fitting 80 is made thicker than the thickness of the light shielding fitting 70.

  Therefore, when the shoji opening prevention metal fitting 80 hits the vertical rail 37, a reliable block is formed without damage to the shoji opening metal prevention fitting 80 due to the thick thickness of the shiso opening prevention metal fitting 80. Ru. Therefore, when a fire occurs, it is possible to more appropriately prevent the door tip 56 from being opened and the passage of the flame being generated.

  Further, in the present embodiment, a metal reinforcing material (reinforcing material 78) continuous in the longitudinal direction of the door tip 56 is inserted into the inside of the engagement groove 60, and the shoji opening prevention fitting 80 is a reinforcement. It was decided that the screw 78 fixed to the material 78.

  Therefore, even if the toe hook 56 is exposed to a flame and melted in the case of a fire, the state in which the shoji opening prevention metal fitting 80 is fixed to the metal reinforcing member (reinforcement member 78) is maintained. Therefore, when a fire occurs, it is possible to more appropriately prevent the door tip 56 from being opened and the passage of the flame being generated.

  Further, in the present embodiment, the frame 20 and the casing 50 (specifically, the upper frame 30 and the lower frame 32, the vertical frame 35 on the left and right, the The upper frame 30 and the upper frame 52 are made of a stainless steel upper frame suspension fitting 31 and an upper frame which are overlapped with each other in the expected direction when the shoji is closed while the front rod 56 and the combined rod 58) are made of synthetic resin. It is assumed that a metal fitting 53 is provided. That is, as shown in FIG. 2, the upper frame suspension bracket 31 and the upper frame suspension bracket 53 are fixed to the upper frame 30 and the upper frame 52, respectively, and overlap each other in the prospective direction when the shoji 40 is closed. It is supposed to (overlap). Then, in this state, when a fire occurs, both of the suspension fittings engage with each other to play a role of suspending the shoji 40. That is, even if the upper frame suspension fitting 31 and the upper frame suspension fitting 53 are exposed to the flame of the synthetic resin frame 20 and the casing 50 and are melted during a fire, the shoji 40 does not fall down (does not fall down) In order to

  And, in the present embodiment, by the action of the above-mentioned upper frame suspending bracket 31 and the upper hook suspending bracket 53, the door hook 56 is relatively difficult to open at the upper portion of the hook (door hook 56). The opening prevention metal fitting 80 is provided at the lower part where the door tip 56 is more easily opened. As described above, in the present embodiment, since the shoji opening prevention fitting 80 is provided at an appropriate position in the door tip 56, the door tip 56 is opened when a fire occurs, and a flame passage is generated. It is possible to prevent things more appropriately.

  Further, in the present embodiment, the metal fitting-side heating foam material 85 is attached to the shoji opening preventing metal fitting 80, and the flame shielding metal fitting-side heating foam material 84 is also attached to the light shielding metal fitting 70, The prevention-metal-side heating foam material 85 and the light-shielding metal fitting-side heating foam material 84 are opposed to each other in a state where the vertical rails 37 are positioned between the two heating foam materials.

  Therefore, when both the heating foams are exposed to the flame in the event of a fire and expand, the vertical rail 37 located between the two will be sandwiched, and it is possible to suppress the vertical rail 37 from being deformed. It becomes. Therefore, the engagement groove portion 60 formed in the door tip 56 is less likely to come off the vertical rail 37, and the door tip 56 is opened more appropriately when a fire occurs to prevent the passage of the flame. It becomes possible.

  Further, in the present embodiment, the rail side heating foam material 86 is attached to the vertical rail 37, and the rail side heating foam material 86 includes the prevention fitting side heating foam material 85 and the flameproof fitting side heating foam material 84. And at least one of the heating foam materials.

  Therefore, since the vertical rail 37 is more reliably sandwiched by the heating foam material, it is possible to more appropriately suppress the deformation of the vertical rail 37. Therefore, the engaging groove portion 60 formed in the toe hook 56 becomes more difficult to be detached from the vertical rail 37, and it is more appropriately prevented that the toe hook 56 opens to cause a flame passage when a fire occurs. It is possible to

=== Other Embodiments ===
The above embodiments are for the purpose of facilitating the understanding of the present invention, and are not for the purpose of limiting the present invention. It goes without saying that the present invention can be modified and improved without departing from the gist thereof, and that the present invention includes equivalents thereof.

  In the above embodiment, the sliding window 10 has been described as an example of the window. However, the present invention is not limited to this. Any window may be used as long as the window is provided with a sliding door with respect to the frame. It does not matter. For example, it may be a single sliding window.

  Further, in the above embodiment, since the specification for the misaligned window 10 assumes that a fire will occur on the outdoor side, the shoji opening prevention fitting 80 is L-shaped, and the overlapping portion A (second prevention fitting portion 80b) is positioned more indoor than the vertical rail 37 in the direction of view.

  However, the present invention is not limited to this, and in the specification assuming that a fire occurs on the indoor side, the overlapping portion A (the second prevention fitting portion 80b) is closer to the longitudinal rail 37 in the prospecting direction. It may be located on the outdoor side. Moreover, when it is set as the specification supposing that a fire will generate | occur | produce on the outdoor side and indoor side, let the shoji opening prevention metal fitting 80 be U-shape, and the superposition part A is outdoor side rather than the longitudinal rail 37 in the direction of anticipation. It may be located indoors.

  Further, in the above embodiment, although the sliding window 10 is a terrace window having a relatively large height dimension, the present invention is not limited to this. For example, a normal sliding window may be used. It is also good. However, in the case where the sliding window 10 is a large terrace window, it is difficult to suppress the opening of the door tip 56 only with the pulling piece 72, and the importance of the shoji opening prevention metal fitting 80 is enhanced. In such a point, the above embodiment is more effective.
