Claims (5)

  1. A single sliding door with an external structure comprising a frame body formed by framing an upper frame, a lower frame, and left and right vertical frames, and a sliding screen arranged within the frame body so as to be slidable in the left and right directions, wherein an opening frame is formed on the indoor side of the frame body along the four sides of an opening that communicates in the indoor and outdoor directions, In the fully closed state of the aforementioned shoji screen, the leading edge of the frame that forms the inner perimeter end supporting the surface material of the top, bottom, left, and right frames is hidden by the opening frame when viewed from the inside.
  2. The aforementioned shoji screen, when fully open, has a door frame hidden within the opening frame as viewed from the interior side, as described in claim 1.
  3. The joinery according to claim 1, wherein the retraction allowance when the fully open shoji screen is retracted into the frame is equal to or greater than the left-right dimension of the shoji screen.
  4. The aforementioned shoji screen is a screen door having a mesh as its surface material and a screen door frame that supports the mesh at its inner peripheral end. The joinery according to any one of claims 1 to 3, wherein, when the screen door is fully closed, the leading edge of the screen door frame is hidden by the opening frame when viewed from the indoor side.
  5. The aforementioned shoji screen comprises a sash shoji screen having a glass surface and a sash frame that supports the glass at its inner peripheral end, and a screen door. The joinery according to claim 4, wherein, when the sash shoji and the screen door are in a fully closed or fully open state, the screen door frame is hidden from view from the indoor side by the sash frame and the opening frame.

Description

This invention relates to building components. Conventionally, sliding doors are known in which the shoji screen moves horizontally along a groove formed in the lower frame of a frame provided in an opening, as shown in, for example, Patent Document 1. Such sliding doors have handles formed on the door frame and meeting frame for sliding the shoji screen. When opening the shoji screen from a closed state, the user places their fingers on the handle and slides the shoji screen in the opening direction. Japanese Patent Publication No. 2017-8601 A perspective view showing a sliding door according to an embodiment of the present invention.Figure 1 is a front view of a sliding door as seen from the inside, showing the shoji screen in a fully closed state.Figure 1 is a front view of a sliding door as seen from the inside, showing the shoji screen in its fully open state.This is a front view of a sliding door attached to the exterior of a building, as seen from the interior, showing the door in a fully closed state.This is a front view from the inside of a sliding door attached to the exterior of a building, showing the shoji screen in its fully open state.Figure 4 shows a cross-sectional view along line I-I, which is a horizontal cross-sectional view of a single sliding door in a fully closed state.Figure 5 shows a cross-sectional view taken along line II-II, which is a horizontal cross-sectional view of a sliding door in its fully open state.Figure 4 shows a cross-sectional view taken along line III-III, which is a vertical cross-sectional view of a single sliding door in a fully closed state.Figure 5 shows a cross-sectional view along line IV-IV, which is a vertical cross-sectional view of a sliding door in its fully open state.This is a perspective view showing the configuration of the extrusion mechanism, with the vertical frame cover omitted.Figure 10 is a side view of the extrusion mechanism as seen from the indoor side. The following description, based on drawings, will explain a sliding door installed in an opening of a building as an example of a building component according to one embodiment of the present invention. The sliding door 1 (joinery) according to this embodiment, shown in Figures 1 to 3, is installed in an opening 2A of a building as shown in Figures 4 and 5. It comprises a frame 2 constructed in a rectangular frame shape with a frame on all four sides, and a sliding screen 3 (sash screen) installed within the frame 2 so as to be slidable in the left-right direction X2. The sliding door 1 is a composite sash made of aluminum and resin. Furthermore, a screen door 5 is installed on the outdoor side of the frame 2 so as to be movable in the left-right direction X2. In the fully open state P2, the shoji screen 3 is configured such that, when viewed from the indoor side, all of the top, bottom, left, and right frames 31-34 are hidden on the door pocket side. In other words, the frame body 2 has an external structure in which the structural body K is provided on the indoor side of the first region R1, which is one of the left and right regions (in this embodiment, the right side when viewed from the indoor side), and the opening frame 20 is formed on the indoor side of the second region R2, which is the other side (the left side when viewed from the indoor side), along the four sides of the opening 2A that communicates in the indoor-outdoor direction X1. Here, the symbol W shown in Figures 6 and 7 represents interior materials, and the symbols T and F shown in Figures 8 and 9 represent ceiling and floor materials, respectively. The interior material W forms the opening 2A of the building, and the opening frame 20 is provided along the opening 2A. In the following explanation, the direction connecting the outdoor and indoor sides is referred to as the indoor-outdoor direction X1, and the horizontal direction connecting the left and right sides when viewed from the direction in which the building's opening 2A penetrates the structural frame K is referred to as the left-right direction X2. Furthermore, each component and part constituting the sliding door 1 is described using the indoor-outdoor direction X1 and the left-right direction X2 in the position where it is installed in the opening 2A. In the left-right direction X2, the direction in which the shoji screen 3 is closed is called the closing direction, and the direction in which it is opened is called the opening direction. As shown in Figures 1 to 3, the frame 2 is formed in a rectangular shape and is an external structure to be placed on the exterior side of a building. The frame 2 has an upper frame 21 and a lower frame 22 that extend in the left-right direction X2, and vertical frames 23 and 24 that connect both ends of the upper frame 21 and both ends of the lower frame 22, respectively, and extend in the up-down direction X3.
