Description

  The present invention relates to an opening device housed in a main body in a frame provided in a building opening, and more particularly to a sash that does not generate a gap between the frame and the main body even when exposed to a high temperature in the event of a fire.

  Many of the opening devices provided in the building opening are configured by placing a shoji as a main body in a frame so as to be freely opened and closed. As such an opening device, for example, a sliding window sash that allows the internal and external shojis to be opened and closed in a sliding manner, or an end edge that opposes the end edge of the hoisting side, with either end of the shoji as the hoisting side. There is a sliding window sash that is supported so that the shoji can be rotated with respect to the frame body with the door side.

  Such an opening device is required to have fireproof performance that maintains a closed state for a certain period of time or more even when a fire occurs. In order to sufficiently secure the fire prevention performance, it is necessary to prevent a gap from being generated between the frame body and the main body constituting the opening device even if the opening device is exposed to a high temperature.

  A shoji which is a main body housed in the frame body is configured by placing a panel body such as a glass plate in a frame formed by assembling an upper heel, a lower heel and a vertical ridge in a square shape. Depending on the type of the opening device, the frame constituting the frame can be attached to the frame at a predetermined position, for example, the position of the arm supporting the shoji, the position of the hinge allowing the shoji to be opened or closed, or the position of locking the shoji. It is restrained.

  When the opening device is exposed to a high temperature in the event of a fire, thermal expansion occurs in each of the casings that make up the casing. At this time, since the position where the saddle material is restrained by the frame body is maintained as it is, warpage occurs in the portion of the saddle material between the restraining portions. Moreover, both ends of the saddle member extend to the inner peripheral surface side of the frame body, and eventually come into contact with the inner peripheral surface. If the heating is further continued, the brazing material cannot be stretched any further, and thus warpage occurs due to buckling deformation. As described above, when the warp material is warped, the airtight material of the frame body that has been in contact with the firewood material is separated, a gap is created and the flame penetrates, and air can pass inside and outside the opening device. This may cause fire spread.

  In order to prevent the vertical rod from buckling and generating a gap between the frame and the frame, conventionally, the size between the frame and the peripheral surface of the frame is increased, and the frame is thermally stretched. In addition, the upper and lower ends do not reach the inner peripheral surface of the upper frame and the lower frame, a mechanism for suppressing warpage is provided in the firewood, or a heating foam material that expands with heat in the event of a fire In order to fill the gaps, etc. An example of such an opening device is disclosed in Patent Document 1.

The upper frame 10 constituting the frame body 1 includes an inner peripheral surface portion 10a facing the upper collar 20, and one end of the arm component 6 is fixed to a suspension side end portion of the inner peripheral surface portion 10a. Moreover, the indoor standing surface part 10b which protrudes toward the inner peripheral side is formed near the indoor side of the inner peripheral surface part 10a. The lower end portion of the indoor standing surface portion 10b is opposed to the indoor side surface of the upper collar 20, and an airtight material 14 is provided at this position so as to abut against the upper collar 20.

  The lower frame 11 constituting the frame body 1 includes an inner peripheral surface portion 11a facing the lower collar 21, and one end of the arm component 6 is fixed to a suspension side end portion of the inner peripheral surface portion 11a. In addition, an indoor standing surface portion 11b is formed at the indoor end portion of the inner peripheral surface portion 11a, and an upper end portion thereof is opposed to the indoor side surface of the lower collar 21, and an airtight material 14 is provided at this position. Abuts against the flange 21.

  The vertical frame 12 constituting the frame body 1 includes an inner peripheral surface portion 12a facing the vertical rod 22, and an indoor standing surface portion 12b protruding toward the inner peripheral side is formed near the indoor side of the inner peripheral surface portion 12a. ing.

  A step portion 20 d is formed on the inner side surface of the upper collar 20, and an outer peripheral edge side from the step portion 20 d is a contact surface portion 20 e that protrudes toward the airtight material 14 side of the upper frame 10. The airtight material 14 of the upper frame 10 contacts the contact surface portion 20e.

  The airtight member 14 provided on the upper collar 20 protrudes from the main body abutting portion 14a that abuts against the abutting surface portion 20e of the upper collar 20 in a state where the shoji 2 is closed, and the upper collar protruding from the upper end of the main body abutting portion 14a. The airtight part 14b which does not contact 20 is integrally formed. The airtight portion 14b is formed in a fin shape having an inclined surface 14c extending from the main body contact portion 14a toward the inner peripheral surface portion 10a side and the upper collar 20 side of the upper frame 10. Hereinafter, the first direction is the direction in which the sash is found and is directed from the center side of the frame 1 toward the inner peripheral surface side, and the second direction is the direction in which the sash is expected and is directed toward the indoor outer surface of the shoji 2 Respectively. According to this, the airtight part 14b extends from the main body contact part 14a in both the first direction and the second direction. Further, the fin shape in the shape of the airtight portion 14b is synonymous with the plate shape, and preferably has elasticity such as rubber or a thin metal plate.

  Since both ends of the upper rod 20 are swallowed and connected to the vertical rod 22, the upper rod 20 is formed narrower than the vertical rod 22 by the thickness of the rib material. On the other hand, the abutting surface portion 20e with which the airtight material 14 abuts needs to be flush with the indoor side surface of the vertical rod 22 in order to ensure airtightness, and thus a step portion 20d is formed. Since the step portion 20d of the upper collar 20 is formed at a position that is substantially flush with the inner peripheral side end face of the hermetic material 14, the step on the indoor surface of the upper collar 20 is made difficult to see from the indoor side. The design can be improved.

  The lower rod 21 constituting the housing 3 includes a panel body storage portion 21a that holds the upper side of the panel body 4 on the inner peripheral side, and an outer peripheral surface portion 21b that faces the inner peripheral surface of the lower frame 11 on the outer peripheral side. ing. One end of the arm component 6 is fixed to the outer peripheral surface portion 21b.

  A step portion 21d is also formed on the inner side surface of the lower rod 21 similarly to the upper rod 20, and an outer peripheral edge side from the step portion 21d is a contact surface portion 21e protruding toward the airtight material 14 side of the lower frame 11. . The reason why the step portion 21 d is formed on the lower collar 21 is the same as that of the upper collar 20. The airtight material 14 of the lower frame 11 contacts the contact surface portion 21e.

  The airtight material 14 provided on the lower collar 21 projects from the main body abutting portion 14a that abuts against the abutting surface portion 21e of the lower collar 21 in a state in which the shoji 2 is closed, and protrudes from the lower end of the main body abutting portion 14a. The airtight part 14b which does not contact 21 is integrally formed. The airtight portion 14b is formed in a fin shape having inclined surfaces 14c extending from the main body contact portion 14a to the inner peripheral surface portion 11a side and the lower collar 21 side of the lower frame 11, that is, the first direction and the second direction. .

  The vertical rod 22 constituting the casing 3 includes a panel body storage portion 22a that holds the vertical side of the panel body 4 on the inner peripheral side, and an outer peripheral surface portion 22b that faces the inner peripheral surface of the vertical frame 12 on the outer peripheral side. I have. As described above, the handle 5 is provided on the vertical shaft 22 on the door end side, and is linked to the lock portion 5a.

  The airtight material 14 provided on the vertical rod 22 protrudes from the main body contact portion 14a that contacts the indoor side surface of the vertical rod 22 with the shoji 2 closed, and the outer peripheral end of the main body contact portion 14a. The airtight part 14b which does not contact is integrally formed. The airtight portion 14b of the airtight material 14 has a fin shape having an inclined surface 14c extending from the main body contact portion 14a to the inner peripheral surface portion 12a side and the vertical flange 22 side of the vertical frame 12, that is, in the first direction and the second direction. Is formed.

  What is provided in the position adjacent to the handle | steering-wheel 5 has the sickle shape, and the lock part 5a is detachable with respect to the lock fixing | fixed part 13a of the vertical frame 13 by the side of a door. Moreover, what is provided in the position away from the handle | steering-wheel 5 among the lock parts 5a has a pin shape, and can be engaged / disengaged with respect to the lock fixing | fixed part 13a. Each lock part 5a is arrange | positioned in the position facing the lock fixing | fixed part 13a of the vertical frame 13 on the door-end side, and the lock part 5a protrudes from the vertical rod 22 on the door-end side by operating the handle 5 Each lock portion 5a is locked to the lock fixing portion 13a, and when the shoji 2 is closed, it is locked and is pulled toward the frame body 1 side to ensure airtightness.

  When a fire occurs and the sash is exposed to a high temperature, each frame material constituting the frame 3 is made of aluminum, so that thermal elongation occurs and warping also occurs between the frame 1 and the frame 1. There may be gaps. The upper collar 20 has a restraining portion 20c. When the housing 3 is exposed to a high temperature from one side inside or outside the room, both sides extend toward the inner peripheral surface portion 12a of the vertical frame 12, and the restraining portion Between the end of 20c and the upper collar 20, it bends so that it may each protrude toward the outdoor side. Similarly, the lower collar 21 is bent so that both sides extend toward the inner peripheral surface portion 12a of the vertical frame 12, and the end side from the restraining portion 21c protrudes toward the outdoor side.

  Since the vertical rod 22 on the suspending side does not have a restraining portion, both sides of the inner peripheral surface portion 10a and the lower frame 11 of the upper frame 10 are provided on both sides when the frame 3 is exposed to high temperature from one side of the room. While extending toward the inner peripheral surface portion 11a, the two end portions are bent so as to protrude toward the outdoor side. The vertical rod 22 on the door end side is the same as the suspension base side in that both sides extend toward the inner peripheral surface portion 10a of the upper frame 10 and the inner peripheral surface portion 11a of the lower frame 11, but are restricted to three places in the longitudinal direction. Since the portions 22c are provided, the portions between the restraining portions 22c are bent so as to protrude toward the outdoor side, and the end portions of the restricting portions 22c are also bent so as to protrude toward the outdoor side.

  FIG. 4 shows a longitudinal sectional view of the sash when a fire breaks out, and FIG. 5 shows a cross-sectional view of the sash when a fire breaks out. As shown in FIG. 4, the upper rod 20 moves upward by the thermal expansion of the vertical rod 22 until the upper end portion of the outdoor side surface abuts against the inner peripheral surface portion 10 a of the upper frame 10. Further, it is deformed to the outdoor side by bending. At this time, the airtight member 14 of the upper frame 10 has the main body contact portion 14a away from the contact surface portion 20e of the upper collar 20, but the inner circumferential surface portion 10a side and the upper collar 20 side of the upper frame 10, that is, the first direction. The inclined surface 14c of the airtight portion 14b extending in the second direction comes into contact with the contact surface portion 20e to form an airtight state. Thereby, it is possible to prevent a gap from being generated between the upper frame 10 and the upper collar 20.

  The airtight member 14 is an elastic body made of a material such as polypropylene, polyethylene, polyvinyl chloride, polyvinyl acetate, silicon rubber, or EPDM. At least the hermetic portion 14b of the hermetic material 14 needs to be formed of a material that does not melt due to heat during a fire in order to maintain hermeticity. For example, it is desirable that ammonium polyphosphate which is a condensed phosphate compound is included as a flame retardant. At this time, the ammonium polyphosphate acts as a dehydration catalyst for the organic matter and carbonizes the organic matter, leading to the formation of a stable carbonized layer even at high temperatures. In addition to the condensed phosphoric acid compound, a metal hydroxide may be included instead. Examples of the metal hydroxide include aluminum hydroxide, magnesium hydroxide, calcium hydroxide, barium hydroxide, zirconium hydroxide and the like. Furthermore, the present invention is not limited to these, as long as the surface is solidified by exposure to high temperatures. By solidifying the surface, it is possible to prevent heat from being transmitted to the portion that is not heated via the airtight material 14. The same applies to the airtight material 14 of the lower frame 11 and the vertical frame 12 as well as the airtight material 14 of the upper frame 10.

  The lower rod 21 moves downward until the lower end portion of the outdoor side surface abuts against the inner peripheral surface portion 11 a of the lower frame 11 due to the thermal elongation of the vertical rod 22. Further, it is deformed to the outdoor side by bending. At this time, the airtight member 14 of the lower frame 11 has the main body contact portion 14a separated from the contact surface portion 21e of the lower collar 21, but the inner peripheral surface portion 11a side and the lower collar 21 side of the lower frame 11, that is, the first direction. The inclined surface 14c of the hermetic portion 14b extending in the second direction comes into contact with the abutting surface portion 21e so as to be in an airtight state. Thereby, it is possible to prevent a gap from being generated between the lower frame 11 and the lower collar 21.

  As shown in FIG. 5, the vertical rod 22 moves to the vertical frame 12 side until the end portion of the outdoor side surface abuts against the inner peripheral surface portion 12 a of the vertical frame 12 due to thermal expansion of the upper rod 20 and the lower rod 21. . Further, it is deformed to the outdoor side by bending. At this time, the airtight member 14 of the vertical frame 12 has an airtight portion 14b extending toward the inner peripheral surface portion 12a side and the vertical rod 22 side of the vertical frame 12, although the main body contact portion 14a is separated from the indoor side surface of the vertical rod 22. The inclined surface 14c comes into contact with the indoor side surface of the vertical rod 22 and is in an airtight state. Thereby, it is possible to prevent a gap from being generated between the vertical frame 12 and the vertical rod 22.

  As described above, the airtight material 14 provided in the frame body 1 includes the main body abutting portion 14a that abuts the housing 3 in a normal state, and the housing when each housing material of the housing 3 is moved and deformed in the event of a fire. 3 is provided with an airtight portion 14b that abuts 3 and the airtight portion 14b is provided with an inclined surface 14c extending in the direction of movement and deformation of the brazing material. Even if warpage occurs, the airtight portion 14b abuts against the housing 3, so that no gap is generated between the frame 1 and the airtight material 14, and the fireproof performance of the sash is improved. Can do.

  The projecting width of the airtight part 14b toward the inner peripheral surface of the frame 1 and the projecting width toward the housing 3 are set based on the maximum movement and deformation amount of the housing 3 assumed when a fire occurs. The projecting width toward the inner peripheral surface of the frame 1 is such that the saddle material moves toward the inner peripheral surface of the frame 1, that is, the size of the gap between the end of the saddle material and the inner peripheral surface of the frame 1. A minute is needed. Moreover, the protrusion width | variety which goes to the housing 3 side needs the magnitude | size for the magnitude | size of the maximum curvature amount with which the magnitude | size which a collar material deform | transforms toward an outdoor side, ie, the collar material.

  The airtight material 14 is provided over the four circumferences of the frame body 1 to ensure airtightness. In this embodiment, since the airtight part 14b is formed integrally with the main body contact part 14a, for example, it is also provided over the four circumferences, but at least the deformation of the saddle material constituting the casing 3 is large. It suffices if it is provided in a region assumed to be. Specifically, since the gap between the upper and lower rods 20, 21 and the vertical rod 22 is unlikely to be generated between the frame 1 and the frame 3, the region between the two constraint portions, If it is assumed that the deformation between the areas between the corners or the corners of the housing 3 is large, the airtight part 14b may be provided near the corners.

  Moreover, since the airtight part 14b is made not to contact the housing 3 in the normal time, the airtight part 14b should not disturb the smooth opening and closing operation when the shoji 2 is opened and closed in the normal time. Can do.

  On the other hand, the airtight part 14b can also be configured to contact the housing 3 in a normal state. FIG. 6 is an enlarged vertical sectional view of the vicinity of the lower frame 11 of the sash when the contact portion of the housing 3 is lengthened, and FIG. 7 is a view of the vicinity of the vertical frame 12 of the sash when the contact portion of the housing 3 is lengthened. Enlarged longitudinal sectional views are shown respectively. As shown in FIG. 6, the contact surface portion 21e of the lower collar 21 is extended to a lower side than that shown in FIG. 4, thereby expanding the contact surface portion 21e. Abut. The airtight part 14b elastically contacts the contact surface part 21e at the center of the inclined surface 14c. Note that the main body contact portion 14a also elastically contacts the contact surface portion 21e. Further, as shown in FIG. 7, the indoor side surface of the vertical rod 22 is extended to the vertical frame 12 side than that shown in FIG. 14b contacts. Also in this case, the central portion of the inclined surface 14 c in the airtight portion 14 b comes into contact with the indoor side surface of the vertical rod 22. Here, although the lower frame 11 and one vertical frame 12 are shown, the upper frame 10 and the other vertical frame 12 can be similarly configured.

  FIG. 8 is an enlarged longitudinal sectional view of the vicinity of the lower frame 11 in the state of the sash fire when the abutting portion of the casing 3 is lengthened, and FIG. 9 is a case where the abutting portion of the casing 3 is lengthened. The enlarged vertical sectional view of the vicinity of the vertical frame 12 in the state at the time of occurrence of the fire of the sash is shown. In some cases, such as when the distance between the restraining portions of the housing 3 is small, the housing 3 does not move so much toward the inner peripheral surface of the frame 1 when a fire occurs.

The airtight part 74b which does not contact is integrally formed, for example. The airtight portion 74b is formed in a fin shape having an inclined surface 74c extending from the main body abutting portion 74a to the inner peripheral surface portion side and the housing 63 side of the frame body 60, that is, the first direction and the second direction.

  When the sash of this embodiment is exposed to the high temperature at the time of fire occurrence, as in the first embodiment and the second embodiment, thermal expansion and warpage occur in each brazing material, and the inner peripheral surface side of the frame 60 And move and deform toward the outdoor side. FIG. 20 shows a vertical cross-sectional view of the sash in the state at the time of the fire, and FIG. 21 shows a cross-sectional view of the sash in the state at the time of the fire.

  As shown in FIG. 20, the upper collar 80 of the outer screen 61 moves upward until it hits the inner peripheral surface portion 70a of the upper frame 70, and further toward the outdoor side until the indoor side face hits the upper rail portion 70d. Deform. Even in this case, the inclined surface 74c of the airtight portion 74b contacts the upper collar 80. Further, the upper collar 80 of the inner impeller 62 moves upward until it hits the inner peripheral surface portion 70a of the upper frame 70, and further deforms toward the outdoor side until the outdoor side surface hits the intermediate standing surface portion 72c. Even in this case, the inclined surface 74c of the airtight portion 74b contacts the upper collar 80. With these, it is possible to prevent a gap from being generated between the upper collar 80 and the upper frame 70.

  When the lower arm 81 of the external shoji 61 is exposed to the high temperature at the time of the fire, the resin door roller 81c melts. As a result, the lower collar 81 of each of the external shoji 61 and the inner shoji 62 moves downward until the housing 63 hits the inner peripheral surface portion 71a of the lower frame 71, and the inner side surface of the lower shovel 81 and the inner shoji 62 further moves to the inner rail portion 71c or the outside. It deforms toward the outdoor side until it hits the rail portion 71e. Even in this case, it is possible to prevent the inclined surface 74c of the airtight portion 74b from coming into contact with the lower rod 81 so that no gap is generated between the lower rod 81 and the lower frame 71.

  As shown in FIG. 21, each vertical rod 82 of the external obstacle 61 and the internal obstacle 62 moves toward the side until it hits the inner peripheral surface portion 72 a of the vertical frame 72 and further deforms toward the outdoor side. Even in this case, since the inclined surface 74c of the airtight portion 74b contacts the vertical rod 82, it is possible to prevent a gap from being generated between the vertical rod 82 and the vertical frame 72.

  Here, in the lower rod 81, the width of the gap between the indoor hanging portion 81b and the inner rail portion 71c or the outer rail portion 71e becomes the maximum amount of deformation toward the outdoor side of the dredging material. The protruding width extending toward the housing 63 side is desirably a width corresponding to the width of the gap between the indoor hanging portion 81b and the inner rail portion 71c or the outer rail portion 71e or larger.

  In the present embodiment, since the airtight portion 74b is not in contact with the housing 63 at the normal time, the airtight portion 74b is prevented from becoming a resistance when opening and closing the external shovel 61 and the internal shroud 62, and smooth opening and closing are performed. Can be made. However, as shown in the first embodiment and the second embodiment, the airtight portion 74b may be in contact with the housing 63 even at the normal time.

  As described above, even in the sliding window sash, the airtight member 74 provided with the airtight portion 74b having the inclined surface 74c allows the hermetic portion 74b to contact the housing 63 even if there is movement and deformation of the saddle. It is possible to increase the fireproof performance without generating a gap between the frame 60 and the casing 63.

  The airtight members 14, 44, 74 in the first to third embodiments may have other shapes as long as they have the inclined surfaces 14c, 44c, 74c. For example, the main body contact portions 14a and 44a have a hollow cross section, and the main body contact portion 74a has a substantially L-shaped cross section, but may have other shapes. The airtight portions 14b, 44b, and 74b are all fin-shaped, but may have other shapes such as a hollow material having a triangular cross section as long as it has an inclined surface. Furthermore, the airtight portions 14b, 44b, and 74b are formed integrally with the main body contact portions 14a, 44a, and 74a, but may be separate from each other, and the main body contact portions 14a, 44a, and 74a. It may be an airtight material that does not have.

  In both the sashes of the first embodiment and the second embodiment, since the shoji opens toward the outdoor side, the airtight members 14 and 44 are in contact with the indoor side surface of the housing, but the shoji is on the indoor side. In this case, the hermetic material is provided so as to abut against the outdoor side surface of the housing. In this case, the inclined surface of the hermetic portion has an inclined surface shape toward the inner peripheral surface side and the housing side of the frame. That is, the inclined surface of the airtight portion is formed so as to extend from the main body contact portion toward the outer peripheral side and the indoor side. When the shoji is configured to open to the indoor side, each frame that forms the frame is bent so that it protrudes toward the indoor side in the event of a fire. It can contact | abut with respect to a housing and can prevent the clearance gap between a frame and a housing.

  Although the embodiment of the present invention has been described above, the application of the present invention is not limited to this embodiment, and can be applied in various ways within the scope of its technical idea.
