Description

[Technical Field]

[0001] The present disclosure relates to a shoji screen. [Background technology]

[0002] Conventionally, there has been known a fitting comprising a frame and a shoji screen placed within the frame (see, for example, Patent Document 1). A shoji screen has a glass panel fitted inside a rectangular frame body made of assembled stiles. The shoji screen described in Patent Document 1 reduces the width of the frame in the front direction, which has a higher thermal conductivity than glass, and minimizes exposure of the frame to the interior of the room, thereby improving the thermal insulation and moisture-proofing performance of the fitting.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-109099 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, in order to ensure the opening and closing operation of a shoji screen, a recessed portion that serves as a handle is sometimes provided in the vertical frame of the shoji screen. However, for the vertical frame described in Patent Document 1, which has a small width in the front direction, it is difficult to secure space on the surface facing the room for providing a recessed portion that serves as a handle. Therefore, there is a demand for providing a handle in a vertical frame that has a small width in the front direction to ensure the opening and closing operation.

[0005] The present disclosure aims to provide a shoji screen that can be opened and closed easily by providing a handle on a vertical frame that has a small width in the front direction. [Means for solving the problem]

[0006] The present disclosure relates to a shoji screen having a frame body with a vertical stile, the vertical stile having a protruding portion provided inside the frame body and protruding toward the inside of the room. [Brief explanation of the drawings]

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0008] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The fitting of this embodiment is a sliding window 1.

[0009] In this specification, "visible direction" refers to the face direction of the panel materials 35, 45 of the sliding window 1 placed in an opening formed in the wall of a building, and "visible direction" refers to the thickness direction (i.e., the depth direction) of the panel materials 35, 45. "Visible direction" also refers to the indoor / outdoor direction. "Visible surface" refers to the surface of the sliding window 1 facing the outside and inside of the room, and "visible surface" refers to the surface of the sliding window 1 extending in the indoor / outdoor direction. In the drawings, the outside side of the sliding window 1 is referred to as the outside side X1, and the inside side of the sliding window 1 is referred to as the inside side X2.

[0010] As shown in Figures 1 and 2, the sliding window 1 comprises a frame body 2 that is attached to an opening in a building frame (not shown), and an outer shoji screen 3 and an inner shoji screen 4 that are arranged inside the frame body 2.

[0011] The frame body 2 is formed by framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24 in a rectangular shape.

[0012] The outer shoji screen 3 and the inner shoji screen 4 are both sliding doors, and are configured to be able to slide left and right (horizontally) in the viewing direction, thereby forming a so-called sliding window in which the opening in the frame body 2 can be closed or opened.

[0013] The outer shoji screen 3 is constructed by fitting a panel 35 made of two pieces of glass inside a rectangular frame body 30 consisting of an upper frame 31, a lower frame 32, a vertical frame 33 located on the door edge, and an outer frame 34, which is a vertical frame located on the door tail. The outer shoji screen 3 is arranged on the outside (X1) of the frame body 2 so that it can move left and right. The frames of the outer shoji screen 3 (the upper frame 31, the lower frame 32, the vertical frame 33 located on the door edge, and the outer frame 34, which is a vertical frame located on the door tail) can be formed, for example, by extruding aluminum. The frame of the outer shoji screen 3 has a higher thermal conductivity than the panel 35 made of glass. Therefore, by reducing the width of the frame in the viewing direction and minimizing exposure of the frame to the inside (X2) as much as possible, the thermal insulation and moisture-proofing performance of the sliding window 1 are improved.

[0014] The inner shoji 4 is constructed by fitting a panel 45 made of two pieces of glass inside a rectangular frame body 40 consisting of an upper frame 41, a lower frame 42, a vertical frame 43 located on the door edge, and an inner joining frame 44 located on the door tail. The inner shoji 4 is arranged on the interior side X2 of the frame body 2 so that it can move left and right. The frames of the inner shoji 4 (the upper frame 41, the lower frame 42, the vertical frame 43 located on the door edge, and the inner joining frame 44 located on the door tail) can be formed, for example, by extruding aluminum. The frame of the inner shoji 4 has a higher thermal conductivity than the panel 45 made of glass. Therefore, by reducing the width of the frame in the front direction and minimizing exposure of the frame to the interior side X2 as much as possible, the thermal insulation and moisture-proofing performance of the sliding window 1 are improved.

[0015] As shown in Fig. 1, a crescent lock 44a for locking the door is provided on the front surface of the inner door frame 44 of the inner shoji screen 4. As shown in Figs. 2 to 4, the vertical frame 43 located on the door end side of the inner shoji screen 4 has an interior projection 438 (protrusion) that forms a handle at the inner end in the left-right direction of the frame body 40.

[0016] As shown in Figure 2, the vertical frame 33 and the outer joining frame 34 of the outer shoji screen 3 each have a composite structure in which resin frame materials 332 and 342 are attached to the indoor side X2 of metal frame materials 331 and 341. The vertical frame 43 and the inner joining frame 44 of the inner shoji screen 4 each have a composite structure in which resin frame materials 432 and 442 are attached to the indoor side X2 of metal frame materials 431 and 441.

[0017] Next, the configuration related to the indoor protrusion 438 that constitutes the handle will be described. As shown in Figures 2 to 4, the vertical frame 43 arranged on the door edge side of the inner shoji screen 4 is provided with the indoor protrusion 438 that constitutes the handle.

[0018] The indoor protrusion 438 protrudes from the indoor surface X2 of the vertical frame 43 arranged on the door edge side of the inner shoji screen 4 toward the indoor side X2 and extends in the vertical direction. The vertical frame 43 arranged on the door edge side of the inner shoji screen 4 is formed with a small width in the front direction. The vertical frame 43 arranged on the door edge side of the inner shoji screen 4 is constructed by combining a metal frame material 431 and a resin frame material 432.

[0019] As shown in Figure 2, in a vertical frame 43 which is a combination of a metal frame material 431 and a resin frame material 432, a panel material swallowing portion 430 is formed on the inside of the vertical frame 43 in the left-right direction, where the left-right ends of the panel material 45 are placed.

[0020] The metal frame 431 is arranged on the outdoor side X1 of the vertical frame 43 located on the door end side. The metal frame 431 has a hollow portion 431a, a vibration-stop member mounting frame 431b formed on the outside of the hollow portion 431a in the left-right direction, and an outdoor frame 431c formed on the outdoor side X1 inside of the hollow portion 431a in the left-right direction. A vibration-stop member 5 that suppresses vibration of the inner shoji screen 4 relative to the vertical frame 24 is arranged in the vibration-stop member mounting frame 431b.

[0021] As shown in FIG. 2, the resin frame member 432 is attached to the interior side X2 of the metal frame member 431. As shown in FIGS. 2 and 5, the resin frame member 432 has a first hollow portion 433 formed on the inside in the left-right direction, a second hollow portion 434 formed on the outside in the left-right direction of the first hollow portion 433, and a T-shaped portion 435 formed at the end of the first hollow portion 433 on the interior side X2 and having a T-shaped cross section. As shown in FIG. 2, the first hollow portion 433 and the second hollow portion 434 of the resin frame member 432 are provided on the interior side, blocking cold air from outside and improving thermal insulation and moisture-proofing performance. The T-shaped portion 435 and a grating channel 439 that holds the end of the vertical frame 43 side of the face material 45 of the inner shoji screen 4 in the left-right direction form an insulated space, improving thermal insulation and moisture-proofing performance.

[0022] As shown in Fig. 5, the first hollow portion 433 and the second hollow portion 434 extend in the up-down direction. A first hook engagement portion 433a is formed on the surface of the inside end portion of the first hollow portion 433 in the left-right direction facing the outside side X1. A second hook engagement portion 434a is formed on the surface of the outside end portion of the second hollow portion 434 in the left-right direction facing the outside side X1. When attaching the resin frame material 432 to the metal frame material 431, the first hook engagement portion 433a and the second hook engagement portion 434a are hooked onto and engaged with the metal frame material 431, as shown in Fig. 2.

[0023] The T-shaped portion 435 constitutes the indoor side X2 portion of the inlet portion 430 of the vertical frame 43. The left and right ends of the surface material arranged in the inlet portion 430 are arranged on the outdoor side X1 of the T-shaped portion 435.

[0024] As shown in Figures 2 and 5, the T-shaped portion 435 has an indoor left-right extending portion 436 that extends inward in the left-right direction from the indoor side end of the first hollow portion 433, an outdoor protruding portion 437 that protrudes from the indoor left-right inner end of the indoor left-right extending portion 436 toward the outdoor side X1, and an indoor protruding portion 438 that protrudes from the indoor left-right inner end of the indoor left-right extending portion 436 toward the indoor side X2.

[0025] As shown in FIG. 5, the indoor-side left-right extending portion 436 is formed in a plate shape extending in the up-down and left-right directions, and extends over the entire area of the first hollow portion 433 in the up-down direction.

[0026] The outdoor protruding portion 437 is formed in a plate shape extending in the vertical direction and the projection direction. The outdoor protruding portion 437 extends in the vertical direction with a length in the vertical direction that is shorter than the length in the vertical direction of the indoor left-right extending portion 436.

[0027] The indoor protruding portion 438 is formed in the shape of a plate extending in the vertical direction and the forward direction. The indoor protruding portion 438 extends in the vertical direction with a length in the vertical direction that is shorter than the vertical length of the indoor left-right extending portion 436 and longer than the vertical length of the outdoor protruding portion 437. The indoor protruding portion 438 forms a handle that the user can place their hand on when opening or closing the inner shoji screen 4.

[0028] The indoor protrusion 438 has a thickness in the left-right direction and is formed in the shape of a plate that protrudes toward the indoor side X2 and extends in the up-down direction. The indoor protrusion 438 forms a handle that can be placed on to open or close the inner shoji screen 4. The indoor protrusion 438 extends along the up-down direction (longitudinal direction) of the inner door frame 44.

[0029] In this embodiment, the vertical frame 43 is a frame with a small width in the front direction. Therefore, even if the vertical frame 43 has a small width in the front direction, such that it does not have the width required to provide a recess as a handle, for example, the indoor protrusion 438 can be formed on the inside of the vertical frame 43 in the left-right direction with a small width in the left-right direction.

[0030] The exterior protrusion 437 and the interior protrusion 438 are formed by cutting out the upper and lower ends of the vertical frame 43 located on the door edge side of the inner shoji screen 4 so as to avoid the L-shaped angle 211 of the upper frame 21 and the L-shaped angle 221 of the lower frame 22, as shown in Figure 4.

[0031] Specifically, as shown in Figure 5, at the upper and lower ends in the vertical direction (longitudinal direction) of the resin frame material 432 of the vertical frame 43, a cutout surface 440 is formed by cutting out a part of the outdoor protruding portion 437 and a part of the indoor protruding portion 438.

[0032] Here, we will explain the procedure for cutting out the upper and lower ends of the resin frame material 432 of the vertical frame 43. The resin frame material 432 is processed to cut out the indoor protrusions 438 at the upper and lower ends of the resin frame material 432, as in the processing steps of Figures 6 and 7.

[0033] First, from the state shown in the leftmost diagram in Figure 6 and the upper left diagram in Figure 7, the outdoor protrusion 437 is cut at the upper and lower ends of the resin frame material 432, as shown in the second diagram from the left in Figure 6 and the lower left diagram in Figure 7, and a process is performed to separate an approximately rectangular outdoor protrusion detachment piece 437a.

[0034] Specifically, as shown in the second figure from the left in Figure 6 and the bottom left figure in Figure 7, the outdoor protruding portion 437 is cut at its upper and lower ends along the left-right direction and the forward direction at the connection with the indoor protruding portion 438 at cutting surface 438d, and cut at its connection with the outdoor protruding portion 437 along the horizontal plane in the forward direction at cutting surface 437c.

[0035] This cuts off the roughly rectangular outdoor protrusion cutout piece 437a from the outdoor protrusion 437. When the outdoor protrusion 437 is cut to separate the roughly rectangular outdoor protrusion separation piece 437a, when the resin frame material 432 is viewed from the inside of the inner shoji screen 4 in the left-right direction, the outdoor protrusion 437 and the indoor protrusion 438 are formed in a stepped shape.

[0036] In this state, as shown in the second figure from the left in Figure 6 and the bottom left figure in Figure 7, the cut surface 438d of the indoor protrusion 438 of the resin frame material 432 faces the outdoor side X1, and the cut surface 437c of the outdoor protrusion 437 of the resin frame material 432 faces upward or downward.

[0037] Next, from the state shown in the second figure from the left in Figure 6 and the lower left figure in Figure 7, the upper and lower ends of the indoor protrusion 438 are cut off as shown in the third figure from the left in Figure 6 and the upper right figure in Figure 7, and a process is performed to separate an approximately rectangular indoor protrusion detachment piece 438a.

[0038] Specifically, as shown in the third diagram from the left in Figure 6 and the top right diagram in Figure 7, the indoor protruding portion 438 is cut at its upper and lower ends along cutting planes 437b along the left-right and up-down directions at the connection portion with the outdoor protruding portion 437.

[0039] Furthermore, at a position a predetermined distance below the upper end of the indoor protruding portion 438 and a position a predetermined distance above the lower end, the outdoor portion X1 is cut along a cutting surface 438b along a horizontal plane in the projection direction, and the indoor portion X2 is cut along a cutting surface 438c that slopes downward toward the viewer relative to the horizontal plane in the projection direction. In this way, a substantially rectangular indoor protruding portion detachment piece 438a is cut off from the indoor protruding portion 438.

[0040] In this state, as shown in the third diagram from the left in Fig. 6 and the upper right diagram in Fig. 7, the cut surfaces 438b, 438c of the outdoor protruding portion 437 of the resin frame material 432 are exposed on the upper or lower side, and the cut surface 437b of the outdoor protruding portion 437 is exposed on the indoor side X2. Here, because the cut surface 437b of the outdoor protruding portion 437 is exposed on the indoor side X2, the cut surface 437b of the outdoor protruding portion 437 can be seen from the indoor side X2.

[0041] Next, from the state shown in the third figure from the left in Figure 6 and the upper right figure in Figure 7, as shown in the fourth figure from the left in Figure 6 and the lower right figure in Figure 7, the upper and lower longitudinal ends of the left-right inner end of the indoor left-right extending portion 436 are cut off to separate an approximately rectangular left-right inner detachable piece 436b.

[0042] Specifically, as shown in the third diagram from the left in Figure 6 and the diagram on the bottom right in Figure 7, at the upper and lower ends of the inner left-right end of the indoor left-right extending portion 436, the indoor protruding portion 438 is cut at the upper and lower ends along cutting plane 436a along the forward and downward directions at the connection portion with the indoor left-right extending portion 436, and cut at cutting plane 438e along the horizontal plane in the forward direction at the connection portion with the indoor protruding portion 438.

[0043] In this state, as shown in the third diagram from the left in Figure 6 and the diagram on the bottom right in Figure 7, the cut surface 436a of the indoor left-right extending portion 436 of the resin frame material 432 is exposed on the inside in the left-right direction, and the cut surfaces 438b, 438c, 438e of the outdoor protruding portion 437 of the resin frame material 432 are exposed on the upper or lower side.

[0044] In this way, by cutting out the upper and lower ends of the resin frame material 432 of the vertical frame 43, a cutout surface 440 can be formed. As shown in Fig. 5, the cutout surface 440 is composed of a cut surface 436a of the indoor-side left-right extending portion 436, cut surfaces 438b, 438c, and 438e of the outdoor-side protruding portion 437, a cut surface 437c of the outdoor-side protruding portion 437, and a cut surface 438d of the indoor-side protruding portion 438. The cut surface 436a of the indoor-side left-right extending portion 436 is a prospective surface facing inward in the left-right direction. The cut surfaces 438b, 438c, and 438e of the outdoor-side protruding portion 437 and the cut surface 437c of the outdoor-side protruding portion 437 are surfaces facing upward or downward. The cut surface 438d of the indoor protruding portion 438 is a visible surface facing the outdoor side X1 and is not visible from the indoor side. In this embodiment, the cutout surface 440 is configured to include a visible surface (the cut surface 436a of the indoor left-right extending portion 436). The cutout surface 440 does not have a visible surface facing the indoor side.

[0045] Here, assuming that the indoor protruding portion 438 is cut along the front direction, the front surface is exposed to the indoor side X2. In contrast to this, in the present embodiment, the cutout surface 440 of the resin frame material 432 is configured to include the front surface (the cut surface 436a of the indoor side left-right extending portion 436). Therefore, a part of the cutout surface 440 (the cut surface 436a of the indoor side left-right extending portion 436) becomes difficult to see from the indoor side X2, and the cutout surface 440 can be made less noticeable when viewed from the indoor side X2.

[0046] As described above, by cutting the upper and lower ends of the resin frame material 432, as shown in the right-hand diagram of Fig. 6 and the bottom diagram of Fig. 7, the cut surface 436a of the indoor-side left-right extending portion 436 of the resin frame material 432 forms a visible surface exposed on the inside in the left-right direction, and the cut surface 438d of the indoor-side protruding portion 438 of the resin frame material 432 forms a visible surface facing the outdoor side X1. As a result, even if the upper and lower ends of the resin frame material 432 are cut out, the cutout surface 440 can be formed without any visible surface exposed on the indoor side X2. Therefore, the cutout surface 440 can be made less noticeable.

[0047] This embodiment provides the following advantages. The shoji screen 4 of this embodiment includes a frame 40 having a vertical stile 43. The vertical stile 43 is provided on the inside of the frame 40, protruding toward the room and having an interior projection 438 that forms a handle. This ensures the opening and closing operation of the inner shoji screen 4 even when the width of the vertical stile 43 in the front direction is reduced to improve thermal insulation and moisture-proofing performance. In other words, by providing the interior projection 438 on a vertical stile 43 with a small width in the front direction, the interior projection 438 can be configured as a handle, ensuring the opening and closing operation of the inner shoji screen 4. This makes it possible to reduce the width of the vertical stile 43 in the front direction while ensuring the opening and closing operation of the inner shoji screen 4.

[0048] In this embodiment, the indoor protrusion 438 is formed extending along the longitudinal direction of the vertical frame 43, and a cutout surface 440 is formed at the longitudinal end of the vertical frame 43 by cutting out a part of the indoor protrusion 438, and the cutout surface 440 is configured to include a visible surface. This makes it possible to form the cutout surface 440 without any visible surface exposed to the indoor side X2. Therefore, the cutout surface 440 can be made less noticeable. This improves the design.

[0049] Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

[0050] For example, in the above embodiment, the indoor protrusion 438 is formed to extend over a wide range in the vertical direction of the vertical frame 43. However, this is not limited to this. For example, the indoor protrusion may be provided on a portion of the vertical frame in the vertical direction. In this case, the indoor protrusion may be provided in one location or in multiple locations. Furthermore, the indoor protrusion 438 does not have to be formed in a plate shape.
