Description

This disclosure relates to building materials.

A known screen door for sliding doors is installed between the sash and the vertical frame of a sliding door, and is folded or rolled up when not in use and unfolded to cover the opening when in use (see, for example, Patent Document 1). This type of screen door is linked to the opening and closing of the sliding door, so the opening can be opened and closed easily. The screen door disclosed in Patent Document 1 is fixed to the vertical frame and detachably attached to the sash with a magnet. When the sliding door moves from a state in which it closes the opening to a specified position in the opening direction, the screen door unfolds to close the opening between the vertical frame and the sash, and when the sliding door moves further in the opening direction, it separates from the sash. For example, in doors installed at indoor and outdoor entrances, such as balcony entrances in high-rise apartment buildings, the screen door can block the opening even when the sliding door is open, restricting movement between indoors and outdoors.

JP 2015-224524 A

Even if a screen door restricts movement between indoors and outdoors by blocking an opening, if the screen door can be easily opened and closed, it may not be able to maintain its blocking of the opening.

The objective of the present disclosure is to provide a fixture that can be switched between a state in which the screen door blocks an opening and a state in which the screen door opens the opening, and that can maintain the state in which the screen door blocks the opening.

In order to achieve the above-mentioned objective, the building fixture of the present disclosure comprises a frame body, a sliding door screen that is supported by the frame body and slides widthwise to open and close an opening, a screen door that is fixed to the leading edge of the sliding door screen and the vertical frame of the frame body and expands and contracts widthwise to close the space between the leading edge of the sliding door screen and the vertical frame that opens the opening, and a screen door fixing switching unit that switches between a screen door fixed state in which the screen door and the leading edge frame are fixed and a screen door unlocked state in which the screen door and the leading edge frame are released, the screen door being positioned on the indoor side of the sliding door screen, and the screen door fixing switching unit having an indoor side operation unit that is attached to the leading edge frame and switches between the screen door fixed state and the screen door unlocked state from the indoor side, and an outdoor side operation unit that is attached to the leading edge frame and switches between the screen door fixed state and the screen door unlocked state from the outdoor side.

The fitting 1 according to this embodiment shown in Figures 1 and 2 is installed in an opening (referred to as a structural opening 12) in an exterior wall 111 on a high floor of a high-rise building. The fitting 1 according to this embodiment is a relatively large fitting 1 with a height of about 3m. The horizontal direction along the exterior wall 111 on which the fitting 1 is installed is the width direction (the direction of arrow X in the figure), and the direction perpendicular to the exterior wall 111 connecting the interior 13 and the exterior 14 is the indoor/outdoor direction (the direction of arrow Y in the figure). The building's structural body, including the exterior wall 111 and floor 112, is the building structural body 11. In this embodiment, the fitting 1 is a single sliding door with a fixed window, and is configured so that the single sliding door shoji (sliding door shoji 4) slides in the width direction on the exterior 14 side of the fixed window.

The fixture 1 has a frame 2, a fixed shoji screen 3, a sliding door shoji screen 4, a screen 5, and a screen fixing switch section 6. The frame 2 is a four-sided frame. The fixed shoji screen 3 is placed on one side of the inside of the frame 2 in the width direction. The area on the other side of the inside of the frame 2 in the width direction from the fixed shoji screen 3 becomes an opening (referred to as an opening 21 inside the frame body, see Figure 1). The sliding door shoji screen 4 is configured to be slidable inside the frame 2, and when placed on one side of the width direction, it opens the opening 21 inside the frame body, and when placed on the other side of the width direction, it closes the opening 21 inside the frame body.

The spring 84 is provided between the second enlarged portion 823 and the rib 832. The spring 84 is a coil spring, and the shaft portion 821 passes through it. The spring 84 presses the regulating pin 82 to the other side in the width direction so as to widen the gap between the second enlarged portion 823 and the rib 832. As a result, when the regulating pin 82 is pushed from the other side in the width direction toward one side and moves to one side in the width direction relative to the door end frame 74, the spring 84 is elastically deformed. When the force pushing the regulating pin 82 toward one side in the width direction is released, the restoring force of the spring 84 presses the regulating pin 82 to the other side in the width direction and moves to the other side in the width direction relative to the door end frame 74. Regarding the position of the regulating pin 82 relative to the door end frame 74, as shown in FIG. 10, the position where the regulating pin 82 is not pressed from the other side in the width direction and is arranged on the other side in the width direction is defined as the first position. Regarding the position of the regulating pin 82 relative to the door end frame 74, as shown in FIG. 5, the second position is when it is pushed from the other side in the width direction, elastically deforming the spring 84 and positioned on one side in the width direction. Even when the regulating pin 82 is positioned in the first position, it does not protrude beyond the regulating pin attachment portion 83 to one side in the width direction.

The convex member 85 is fixed to one side of the width of the vertical frame inner plate portion 242 of the vertical frame 25, and protrudes from the vertical frame inner plate portion 242 to one side in the width direction. The convex member 85 is arranged at a position where it overlaps with the regulating pin 82 in the width direction. The convex member 85 is formed in a shape that allows it to be inserted from one side in the width direction into the regulating pin mounting hole portion 831 of the regulating pin mounting portion 83. Therefore, when the sliding door screen 4 closes the frame body opening 21 and the door end frame 74 and the vertical frame 25 are close to each other, the convex member 85 enters the regulating pin mounting hole portion 831 of the regulating pin mounting portion 83 and pushes the regulating pin 82 to one side in the width direction. This causes the spring 84 to elastically deform, and the regulating pin 82 is arranged in the second position. As shown in FIG. 10, when the sliding door screen 4 opens the opening 21 inside the frame and the door end frame 74 and the vertical frame 25 separate, the convex member 85 separates from the restricting pin 82, and the restoring force of the spring 84 returns the restricting pin 82 to the first position.

The regulating pin 82 is restricted from moving up and down relative to the door end frame 74, but can move in the width direction. The regulating plate 81 is included in the interlocking portion 67 as described above, and can move up and down relative to the door end frame 74. The regulating plate 81 is restricted from moving in the width direction relative to the door end frame 74. The regulating pin 82 is positioned so as to overlap the regulating hole portion 843 of the regulating plate 81 in the width direction, and one side in the width direction penetrates the regulating hole portion 843 of the regulating plate 81. When the regulating pin 82 is in the first position, the first enlarged portion 822 penetrates the regulating hole portion 843, and when the regulating pin 82 is in the second position, the shaft portion 821 penetrates the regulating hole portion 843.

When the regulating pin 82 is in the second position, the shaft 821 penetrates the regulating hole 843, so that the regulating plate 81 can be displaced in the vertical direction from the height at which the shaft is disposed in the upper hole 844 to the height at which the shaft is disposed in the lower hole 845 through the groove hole 846. In contrast, when the regulating pin 82 is in the first position, the first enlarged diameter portion 822 penetrates the regulating hole 843, so that the first enlarged diameter portion 822 cannot pass through the groove hole 846. As a result, the regulating plate 81 is constrained to either the height at which the first enlarged diameter portion 822 is disposed in the upper hole 844 or the height at which the first enlarged diameter portion 822 is disposed in the lower hole 845, and cannot be displaced in the vertical direction. When the regulating plate 81 is disposed in the fixed position moved upward, the lower hole 845 is disposed at the height of the regulating pin 82, and when the regulating plate 81 is disposed in the fixed release position moved downward, the upper hole 844 is disposed at the height of the regulating pin 82.

When the sliding door screen 4 with the regulating pin 82 in the second position closes the opening 21 inside the frame body, the regulating plate 81 is able to move in the vertical direction, so the interlocking part 67 can be moved in the vertical direction, and it is possible to switch between the screen fixed state and the screen unlocked state. When the sliding door screen 4 with the regulating pin 82 in the first position opens the opening 21 inside the frame body, the vertical movement of the regulating plate 81 is restricted, so the vertical movement of the interlocking part 67 is restricted, and it is not possible to switch between the screen fixed state and the screen unlocked state.

The movement restricting portion 66 shown in FIG. 8 is a stopper that restricts the opening of the sliding door screen 4. In this embodiment, the movement restricting portion 66 restricts the sliding door screen 4 from moving further to an open state when it is opened by 300 mm. The movement restricting portion 66 is attached to the upper end of the interlocking rod 65. When the interlocking rod 65 is in the fixed position, the movement restricting portion 66 protrudes above the upper surface of the upper frame 71 (the state shown in FIG. 8), and when the interlocking rod 65 is in the unlocked position, the movement restricting portion 66 is positioned below the upper surface of the upper frame 71. The position of the movement restricting portion 66 that protrudes above the upper surface of the upper frame 71 is the fixed position, and the position of the movement restricting portion 66 that is positioned below the upper surface of the upper frame 71 is the unlocked position.

When the sliding door screen 4 moves from the closed state to the open state with the movement restriction part 66 arranged in the fixed position, when the sliding door screen 4 moves a predetermined distance (e.g. 300 mm) toward the open position, the movement restriction part 66 comes into contact with the movement restriction receiving part 661 provided on the frame body 2, and the movement of the sliding door screen 4 to the open position is restricted. In this embodiment, the lever 612, 622 of either the indoor side operation part 61 or the outdoor side operation part 62 is operated to fix the screen screen. When the sliding door screen 4 is opened in this state, the frame fixing part 53 of the screen screen 5 moves together with the door end frame 74, the mesh material 51 between the frame fixing part 53 and the frame fixing part 52 spreads, and the spread mesh material 51 blocks the opening between the door end frame 74 and the vertical frame 25. When the door end frame 74 moves a specified distance toward the open position, the movement restriction part 66 comes into contact with the movement restriction receiving part 661 provided on the upper frame 22, restricting the opening of the sliding door screen 4.

The fitting 1 according to the above embodiment has a screen door fixing switch 6 that switches between a screen door fixed state and a screen door released state. In the screen door fixed state, the screen door 5 is fixed to the door end frame 74, and when the sliding door screen 4 opens the opening 21 inside the frame body, the mesh material 51 of the screen door 5 blocks the opening 21 inside the frame body. In the screen door released state, the fixation between the screen door 5 and the door end frame 74 is released, and even if the sliding door screen 4 opens the opening 21 inside the frame body, the mesh material 51 of the screen door 5 does not block the opening 21 inside the frame body. As a result, if the screen door is fixed in the state by the screen door fixing switch 6, the screen door 5 can maintain the state of blocking the opening 21 inside the frame body even if the sliding door screen 4 opens the opening 21 inside the frame body.

In the fitting 1 according to the above embodiment, the indoor operation unit 61 and the outdoor operation unit 62, which are used to switch between the screen fixed state and the screen unlocked state, are located at a height of 1500 mm or more above the floor 112 of the room in which the fitting 1 is installed. This prevents small children from accidentally touching the indoor operation unit 61 and the outdoor operation unit 62 to switch between the screen fixed state and the screen unlocked state, improving the safety of the fitting 1.

In the fitting 1 according to the above embodiment, the screen fixing switching unit 6 has a switching restriction unit 64 that allows switching between the screen fixing state and the screen releasing state when the sliding door screen 4 closes the opening 21 inside the frame body, and prevents switching between the screen fixing state and the screen releasing state when the sliding door screen 4 opens the opening 21 inside the frame body. Therefore, when the sliding door screen 4 opens the opening 21 inside the frame body and the screen screen 5 blocks the opening 21 inside the frame body, the screen fixing state and the screen releasing state cannot be switched. As a result, when the sliding door screen 4 opens the opening 21 inside the frame body and the screen screen 5 blocks the opening 21 inside the frame body, the screen screen 5 does not move to open the opening 21 inside the frame body, improving the safety of the fitting 1.

In the fitting 1 according to the above embodiment, the switching regulating section 64 has a regulating pin 82 attached to the door end frame 74 and a convex member 85 attached to the vertical frame 25, and when the regulating pin 82 and the convex member 85 come into contact, switching between the screen fixed state and the screen unlocked state becomes possible, and when the regulating pin 82 and the convex member 85 separate, switching between the screen fixed state and the screen unlocked state becomes impossible. In this way, with a simple structure that switches between a state in which the regulating pin 82 and the convex member 85 are in contact with each other and a state in which they are separated, it is possible to realize the regulation of switching between the screen fixed state and the screen unlocked state.

In the above embodiment of the fixture 1, the screen door fixing switching section 6 has a movement restriction section 66 that restricts the movement range of the sliding door screen 4 when the screen door is fixed. This makes it possible to simultaneously switch the screen door 5 and restrict the movement range of the sliding door screen 4.
