[Effects of the Invention]

[0009] According to the present invention, Excellent heat insulation We can provide joinery. [Brief explanation of the drawing]

[0010] [Figure 1] This is a front view showing one embodiment of a joinery according to the present invention. [Figure 2] Figure 1 is a schematic diagram illustrating the opening and closing operation of the door / window fixture. [Figure 3] This is an enlarged cross-sectional view of the joint between the first and second shoji screens in the joinery shown in Figure 1. [Figure 4] Figure 1 is an enlarged cross-sectional view of the joint showing the opening and closing operation of the first sliding door in the joinery shown. [Modes for carrying out the invention]

[0011] Embodiments of the present invention will be described in detail below with reference to the drawings. Figure 1 is a front view showing one embodiment of the joinery according to the present invention, showing the joinery as viewed from the inside. This joinery 1 has four sliding doors 3 to 6 inside a rectangular frame 2 formed by an upper horizontal frame 21, a lower horizontal frame 22, and a pair of left and right vertical frames 23, 23. Figure 1 shows the state in which all four sliding doors 3 to 6 are closed. The joinery 1 is configured to separate the inside from the outside when the four sliding doors 3 to 6 are closed in this manner.

[0012] Of the four shoji screens 3-6, the two centrally located screens 4 and 5 are attached to the frame 2 so as to slide left and right along the same rail (not shown) formed on the upper horizontal frame 21 and the lower horizontal frame 22. The two screens 3 and 6 at both ends are also attached to the frame 2 so as to slide left and right along the same rail (not shown) that is parallel to the rail on the outdoor side of the rail on which the central screens 4 and 5 slide.

[0013] In this joinery 1, the sliding screens 3 and 6 at both ends are abutted against the vertical frames 23 and 23, respectively, and the sliding screens 4 and 5, which are located on the indoor side of these sliding screens 3 and 6, are abutted together in the center of the joinery 1 to close it. When closed, a joint 10 is formed in the center of the joinery 1 between the sliding screens 4 and 5. In this joinery 1, one of the two sliding screens 4 and 5 located in the center (the right side in Figure 1) corresponds to the first sliding screen of the present invention, and the other sliding screen 4 (the left side in Figure 1) corresponds to the second sliding screen of the present invention.

[0014] In the shoji screen 4, the glass G is housed inside a rectangular frame formed by an upper frame 41 and a lower frame 42 extending horizontally, a butt joint frame 43 extending vertically on the door edge side (right side in Figure 1) of the shoji screen 4, and a vertical frame 44 extending vertically on the door edge side (left side in Figure 1) of the shoji screen 4. Similarly, in the shoji screen 5, the glass G is housed inside a rectangular frame formed by an upper frame 51 and a lower frame 52 extending horizontally, a butt joint frame 53 extending vertically on the door edge side (left side in Figure 1) of the shoji screen 5, and a vertical frame 54 extending vertically on the door edge side (right side in Figure 1) of the shoji screen 5. Note that the butt joint frame 43 of the shoji screen 4 in Figure 1 is hidden from view by the butt joint frame 53 of the shoji screen 5, as will be described in detail later. The central shoji screens 4 and 5 are closed by their respective abutting frames 43 and 53 coming together, and the abutting frames 43 and 53 that come together in the center form the abutting section 10.

[0015] The glass G is housed inside the rectangular frame of the shoji screens 3 and 6, which are each framed by upper frames 31 and 61 and lower frames 32 and 62 extending horizontally, and vertical frames 33, 34, 63, and 64 extending vertically. In Figure 1, the vertical frame 33 located on the door edge side of shoji screen 3 (right side in Figure 1) is hidden from view by the vertical frame 44 of shoji screen 4. Similarly, the vertical frame 63 located on the door edge side of shoji screen 6 (left side in Figure 1) is hidden from view by the vertical frame 54 of shoji screen 5. On the indoor and outdoor sides of the vertical frames 34 and 64 of shoji screens 3 and 6, respectively, handles 35 and 65 for opening and closing operations are recessed along the extension direction of the vertical frames 34 and 64 (up and down direction in Figure 1).

[0016] Around the middle in the vertical direction of the furniture 1, crescent locks 7, 7 for locking both are attached across the shoji 3 and the shoji 4 and across the shoji 5 and the shoji 6, respectively. Further, auxiliary locking mechanisms 8, 8 for locking the shoji 4 and the shoji 5 are attached to the lower frames 32, 62 of the shoji 3, 6, respectively.

[0017] Next, with reference to FIG. 2, the schematic shapes of the shoji 4 and 5 and the opening and closing operations of the shoji 5 will be described. FIG. 2 is a schematic diagram for explaining the opening and closing operations of the furniture 1, and shows the shoji 3 to 6 in a plan view. In FIG. 2, illustration of the two rails on which the shoji 3 to 6 slide is omitted. The butting frame 43 disposed on the door tip side of the shoji 4 is formed in a shape that projects toward the outdoor side in the prospective direction (the indoor-outdoor direction, which is the vertical direction in FIG. 2). Specifically, the butting frame 43 projects and protrudes in a substantially vertical direction toward the outdoor side, and the protruding portion is formed in a shape displaced toward the shoji 5 so as to cover the finding surface 53b (see FIG. 3) on the outdoor side of the butting frame 53 of the shoji 5.

[0018] The vertical frame 44 on the door butt side of the shoji 4 is formed in a shape that projects toward the indoor side in the prospective direction. Specifically, the vertical frame 44 projects and protrudes in a substantially vertical direction toward the indoor side, contrary to the butting frame 43. This vertical frame 44 is disposed at a position overlapping the vertical frame 33 of the shoji 3 so as to cover the vertical frame 33 of the shoji 3 from the indoor side.

[0019] On the other hand, the butting frame 53 disposed on the door tip side of the shoji 5 is formed in a shape that projects toward the indoor side in the prospective direction, contrary to the butting frame 43 of the shoji 4. Specifically, the butting frame 53 projects and protrudes in a substantially vertical direction toward the indoor side, and the protruding portion is formed in a shape displaced toward the shoji 4 so as to cover the finding surface 43b (see FIG. 3) on the indoor side of the butting frame 43 of the shoji 4.

[0020] The vertical frame 54 on the door end side of the shoji 5 is also formed in a shape that protrudes toward the indoor side in the prospective direction, similar to the butting frame 53. Specifically, the vertical frame 54 protrudes so as to project in a substantially vertical direction toward the indoor side, similar to the butting frame 53. The vertical frame 54 of this shoji 5 is arranged at a position overlapping with the vertical frame 63 of the shoji 6, so as to cover the vertical frame 63 of the shoji 6 from the indoor side.

[0021] When opening and closing the shoji 5 from the indoor side, grasp the butting frame 53 of the shoji 5 that protrudes toward the indoor side by hand and slide it in the direction of the white arrow. That is, the sliding movement of the shoji 5 is performed by grasping the butting frame 53 by hand.

[0022] Next, a more specific configuration of the butting frames 43 and 53 of these shojis 4 and 5 will be described using FIG. 3. FIG. 3 is an enlarged cross-sectional view of the butting portion 10 between the shoji 4 and the shoji 5 in the furniture 1 shown in FIG. 1. In FIG. 3, the shoji 4 and the shoji 5 are arranged so as to be slidable on the same rail 221.

[0023] The butting frame 43 of the shoji 4 is extruded from a metal material such as aluminum and houses three pieces of glass G arranged at intervals by a spacer S through a gasket 4a. The butting surface (the surface that abuts against the shoji 5) 43a of the butting frame 43 integrally has a standing wall portion 431 that rises substantially vertically toward the shoji 5. The finding surface 43b on the indoor side of the butting frame 43 is covered with a resin cover 432. Thereby, the shoji 4 is excellent in heat insulation.

[0024] The butt joint frame 43 integrally has a frame covering portion 433 that protrudes outward toward the outside. The frame covering portion 433 is formed along the extension direction of the butt joint frame 43 (vertical direction in Figure 1). The frame covering portion 433 integrally comprises a first wall portion 433a that rises substantially perpendicular to the glass G surface of the shoji screen 4 (the outdoor side of the glass G), a second wall portion 433b that bends from the outdoor end of the first wall portion 433a toward the shoji screen 5 and extends substantially parallel to the glass G surface of the shoji screen 4, a third wall portion 433c that bends from the end of the second wall portion 433b toward the shoji screen 5 and extends substantially parallel to the first wall portion 433a, and a fourth wall portion 433d that extends from the end of the third wall portion 433c toward the abutting surface 43a, and its cross-section is formed in a substantially rectangular shape.

[0025] The surface of the second wall portion 433b forms the visible surface on the outdoor side of the butt joint frame 43 and the frame covering portion 433. This second wall portion 433b protrudes toward the shoji screen 5 side from the butt joint surface 43a of the butt joint frame 43. The second wall portion 433b extends significantly toward the shoji screen 5 side from the butt joint surface 43a, substantially covering the entire visible surface 53b on the outdoor side of the butt joint frame 53 of the shoji screen 5. As a result, the outdoor side of the butt joint frame 43 is displaced toward the shoji screen 5 side. Therefore, when the joinery 1 is observed from the outdoor side, the width of the butt joint portion 10 is substantially narrow, equal to the width of the visible surface of the butt joint frame 43 of the shoji screen 4 (the width of the second wall portion 433b), thereby improving the aesthetic design of the joinery 1.

[0026] Meanwhile, the butt joint frame 53 of the shoji screen 5 also houses three panes of glass G spaced apart by spacers S, via a gasket 5a. The exterior-facing surface 53b of the butt joint frame 53 extends toward the shoji screen 4 from the butt joint surface 53a and overlaps with the vertical wall portion 431 formed on the butt joint surface 53a of the shoji screen 4's butt joint frame 43. A first airtight seal 531 is attached to the tip of the extended surface 53b, sealing the gap between it and the vertical wall portion 431.

[0027] Furthermore, the butt joint frame 53 has a frame covering portion 533 that protrudes inward towards the indoor side at the indoor end of the butt joint surface 53a, via a bridge portion 532 for insulation. The frame covering portion 533 is connected to the bridge portion 532 and consists of a frame covering portion body 534 integrally extruded from a metal material such as aluminum, and a resin cover 535 that covers the outside of the frame covering portion body 534.

[0028] The frame covering body 534 integrally comprises a first wall portion 534a that rises substantially perpendicular to the glass G surface of the shoji screen 5 (the indoor side of the glass G), a second wall portion 534b that bends from the outdoor end of the first wall portion 534a toward the shoji screen 4 and extends substantially parallel to the glass G surface of the shoji screen 5, a third wall portion 534c that bends from the shoji screen 4 end of the second wall portion 534b toward the outdoor side and extends substantially parallel to the first wall portion 534a, a fourth wall portion 534d that bends from the outdoor end of the third wall portion 534c toward the shoji screen 5 and extends substantially parallel to the second wall portion 534b, and a fifth wall portion 534e that bends from the shoji screen 5 end of the fourth wall portion 534d toward the outdoor side and is connected to the bridge portion 532.

[0029] Of these, the second wall portion 534b protrudes toward the shoji screen 4 side from the abutting surface 53a of the abutting frame 53. The second wall portion 534b extends significantly toward the shoji screen 4 side, parallel to the surface of the glass G, and substantially covers almost the entire resin cover 432 that constitutes the outdoor-facing surface 43b of the abutting frame 43 of the shoji screen 4. As a result, the abutting frame 53 is displaced toward the shoji screen 4 side. The resin cover 535 of the abutting frame 53 covers the outside (indoor side) of the first wall portion 534a, the second wall portion 534b, and the third wall portion 534c. Therefore, when the door 1 is observed from the inside, the width of the abutting joint 10 is narrow, as shown in Figure 1, and is essentially only the width of the visible surface of the abutting frame 53 of the shoji screen 5 (the indoor side of the resin cover 535), thereby improving the design of the door 1. In addition, the presence of the resin cover 535 provides excellent heat insulation to the shoji screen 5.

[0030] A second airtight material 536 is housed in the abutting surface 53a of the abutting frame 53, sealing the space between the abutting surfaces 43a, 53a of the abutting frames 43, 53.

[0031] A large space 100 is provided between the fourth wall portion 534d and the resin cover 432 of the butt joint frame 43 of the shoji screen 4. This space 100 is located where the frame covering portion 533 of the butt joint frame 53 of the shoji screen 5 and the indoor-facing surface 43b of the butt joint frame 43 of the shoji screen 4 face each other. Specifically, this space 100 is large enough for a finger to be inserted when gripping the frame covering portion 533 while opening and closing the shoji screen 5.

[0032] A cushioning member 9 made of an elastic material such as rubber is provided in this space 100. In this embodiment, the cushioning member 9 is attached to the outdoor side surface of the fourth wall portion 534d of the frame covering portion 533 so as to protrude toward the indoor side visible surface 43b of the butt joint frame 43. The cushioning member 9 has a side portion 91 that extends substantially parallel to the door end surface 533a located on the shoji screen 4 side of the frame covering portion 533 and is arranged substantially flush with the door end surface 533a. Therefore, in the space 100, the cushioning member 9 is positioned so as to be exposed toward the shoji screen 4 side (left side in Figure 3) on the door end surface 533a. Since the side portion 91 is substantially flush with the door end surface 533a, as shown in Figure 3, it functions to close the space 100 when the shoji screens 4 and 5 are closed. For this reason, there is no risk of the design of the butt joint portion 10 being impaired from the indoor side.

[0033] As shown in Figure 3, the buffer member 9 has an integral projection 92 that contacts the indoor-side visible surface 43b (resin cover 432) of the butt joint frame 43 when the sliding doors 4 and 5 are closed. In this way, the buffer member 9 also functions as a third airtight seal that seals the space between the buffer member 9 and the indoor-side visible surface 43b of the butt joint frame 43.

[0034] Furthermore, the cushioning member 9 has a hollow portion 93. As a result, the cushioning member 9 has excellent shape retention due to the air in the hollow portion 93, and does not impair the design. Moreover, when an external force is applied, the hollow portion 93 (air) is compressed, allowing it to deform with appropriate elasticity (cushioning properties).

[0036] The buffer member 9 may be attached to the visible surface 43b on the indoor side of the sliding door 4, but as shown in this embodiment, when it is attached to the butt joint frame 53 side of the sliding door 5, the buffer member 9 is not exposed to the indoor side when the sliding door 4 or sliding door 5 is opened, and is not directly visible from the indoor side, thus further improving the aesthetic appearance of the joinery 1.

[0037] The shoji screens 3 and 6 positioned at both ends of the joinery 1 shown in Figure 1 may be fixed immovably to the frame 2. Furthermore, the shoji screens of the joinery 1 in this invention are not limited to four; it is sufficient if at least two shoji screens are configured to close together by butting them.
