Description

[Technical field]

[0001] The present disclosure relates to partition windows. [Background technology]

[0002] Conventionally, there is known a technique for installing a partition window that divides an indoor space (for example, see Patent Document 1). A partition window is configured with a frame body having an upper frame, a lower frame, and a pair of vertical frames, and a paper screen that is placed inside the frame body.

[0003] In the partition window of Patent Document 1, in the lower corner portion which is formed by combining a bottom frame and a vertical frame, the bottom frame and the vertical frame are combined in a so-called vertical-overlap fit, in which the left and right ends of the bottom frame are positioned inside the prospective direction of the vertical frame. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2013-213310 A Summary of the Invention [Problem to be solved by the invention]

[0005] In a partition window, if the bottom frame and vertical frames are fitted together in a so-called horizontal manner, the vertical line of the vertical frame will be interrupted halfway at the lower corners, which would result in an untidy design. Therefore, from a design standpoint, the windows are sometimes fitted together in a vertical manner, as in the partition window described in Patent Document 1.

[0006] On the other hand, in the lower corner, when the lower frame and the vertical frame are combined in a so-called vertical win fit, the left and right ends of the lower frame are placed inside the vertical frame in the projection direction. Here, when the vertical frame is formed by extrusion molding, the ribs rising from the inner surface of the vertical frame are also provided over the entire length of the vertical frame. Therefore, if the left and right ends of the lower frame are placed inside the projection direction of the vertical frame, they will come into contact with the ribs rising from the inner surface of the vertical frame, so it is necessary to cut out the ribs of the vertical frame. Cutting out the ribs of the vertical frame incurs costs for processing the vertical frame.

[0007] Therefore, it is desirable to be able to reduce the processing costs of the frame while maintaining the design in the lower corner portion of a partition window, which is formed by combining the bottom frame and vertical frame.

[0008] The present disclosure aims to provide a partition window that can reduce the processing costs of the frame while maintaining design at the lower corner portion formed by combining a bottom frame and a vertical frame. [Means for solving the problem]

[0009] The present disclosure relates to a partition window which divides a space within a room, comprising a frame body formed by framing an upper frame, a lower frame and a pair of vertical frames, and a shoji screen which is disposed within the frame body and has a resin frame body and a surface material disposed within the frame body, wherein the lower frame is disposed in a recess formed by recessing from the floor surface of the room, and in a lower corner portion formed by combining the vertical frames and the lower frame, at least a portion of the lower end of the vertical frame is disposed on an upper surface of the lower frame.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, an embodiment of the present disclosure will be described in detail with reference to the drawings. In this specification, the term "view direction" refers to the surface direction of the glass in the partition window 1, and the term "projection direction" refers to the thickness direction of the glass. The "projection direction" is also the depth direction in FIG. 1.

[0012] As shown in Fig. 1, a partition window 1 of the present disclosure is installed in a room 10. The partition window 1 divides the interior space of the room 10 into a room 101 on the back side and a room 102 on the front side. The partition window 1 is formed in a wall shape that is fixed to a floor recess 15 (recess), left and right wall surfaces 12, and a ceiling 13 of the room 10 midway in the depth direction of the room 10.

[0013] As shown in Figures 1 and 2, the room 10 has a floor surface 11, a floor recess 15 (recess) formed by recessing downward from the floor surface 11, and a baseboard 16 arranged at the boundary between the floor surface 11 and the wall surface 12.

[0014] As shown in Fig. 2, the floor recess 15 has a predetermined width in the depth direction and extends in the left-right direction along the boundary line between the back room 101 and the front room 102 as shown in Fig. 1. As shown in Fig. 2, the floor recess 15 has a bottom surface portion 151 and a pair of inner side surface portions 152 (inner surfaces) extending upward from both ends of the bottom surface portion 151 in the prospective direction. In the floor recess 15, the lower end portion of the partition window 1 is disposed.

[0015] The partition window 1 of this embodiment can be constructed using a window designed as an inner window of a double-glazed window composed of an outer window and an inner window. For example, the partition window 1 is a window designed as an inner window constituting the interior window of a double-glazed window, which is installed midway in the depth direction of a room 10, and divides the room 10 into a room 101 on the back side and a room 102 on the front side.

[0016] As shown in Figs. 1 to 3, the partition window 1 comprises a frame 2, and a first shoji screen 3 (shoji screen) and a second shoji screen 4 (shoji screen) that are arranged within the frame 2 so as to be able to be opened and closed. The first shoji screen 3 is arranged on the side of the room 101 at the back. The second shoji screen 4 is arranged on the side of the room 102 at the front. The first shoji screen 3 and the second shoji screen 4 are both sliding doors that are configured to be slidable in the left-right direction (horizontal direction) in the front direction, thereby forming a so-called sliding window in which the opening of the frame 2 can be closed or opened.

[0017] The first shoji screen 3 has a resin frame 31 and glass 35 (face material) arranged within the frame 31. The frame 31 is formed by framing an upper frame 32, a lower frame 33, and a pair of vertical frames 34, 34. The second shoji screen 4 has a resin frame 41 and glass 45 (face material) arranged within the frame 41. The frame 41 is formed by framing an upper frame 42, a lower frame 43, and a pair of vertical frames 44, 44.

[0018] In this embodiment, the frame 31 of the first shoji 3 and the frame 41 of the second shoji 4 are made of resin. The upper frame 32, the lower frame 33, and the pair of vertical frames 34, 34 constituting the frame 31, and the upper frame 42, the lower frame 43, and the pair of vertical frames 44, 44 constituting the frame 41 are each made of a resin frame formed by extrusion molding of a synthetic resin such as polyvinyl chloride resin.

[0019] Here, in a double-glazed window consisting of an outer window and an inner window, the inner window is placed in the indoor space and is required to have heat insulating and airtight properties, so the frame of the inner window's shoji is often made of resin, which has high heat insulating and airtight properties. Therefore, the partition window 1 of this embodiment is also designed as the inner window of a double-glazed window consisting of an outer window and an inner window, and uses a frame of the shoji made of resin. As a result, in this embodiment, by making the frame 31 of the first shoji 3 and the frame 41 of the second shoji 4 in the partition window 1 out of resin, it is possible to improve the heat insulating and airtight properties.

[0020] A first shoji screen 3 and a second shoji screen 4 are attached to the inside of the frame body 2. The frame body 2 is configured as a rectangular frame made of a long upper frame 21, a lower frame 22, and left and right vertical frames 23. The upper frame 21, the lower frame 22, and the left and right vertical frames 23 are fixed to the left and right wall surfaces 12, respectively. The upper frame 21 and the left and right vertical frames 23 are configured as resin frames made of resin, for example, formed by extrusion molding of a synthetic resin such as polyvinyl chloride resin. The lower frame 22 is formed, for example, by extrusion molding of a metal such as aluminum material.

[0021] As shown in Fig. 1, the upper frame 21 extends in the left-right direction (horizontal direction) in the front direction at the top of the frame body 2. As shown in Fig. 2, the upper frame 21 has an upper frame upper surface panel portion 211, a first shoji upper frame downward protruding rail 212, a second shoji upper frame downward protruding rail 213, and an upper frame near side downward extending plate 214.

[0022] The upper frame upper plate portion 211 is disposed on the upper portion of the upper frame 21, and is formed as a horizontal plate extending in the projection direction. The first shoji upper frame downward protruding rail 212 protrudes downward from the lower surface of the rear side of the upper frame upper plate portion 211. The second shoji upper frame downward protruding rail 213 protrudes downward from the lower surface of the front side of the upper frame upper plate portion 211.

[0023] The first shoji screen 3 can slide left and right in the front view inside the frame body 2 by the upper end of the first shoji screen 3 being guided by the first shoji screen upper frame downward protruding rail 212. The second shoji screen 4 can slide left and right in the front view inside the frame body 2 by the upper end of the second shoji screen 4 being guided by the second shoji screen upper frame downward protruding rail 213.

[0024] The upper frame front downward extension plate 214 is arranged on the front side of the second shoji screen 4 and extends downward a predetermined length from the front end of the upper frame upper panel portion 211 in the projection direction (depth direction).

[0025] 1, the lower frame 22 extends in the left-right direction (lateral direction) in the front view direction at the bottom of the frame body 2. The lower frame 22 is placed in the floor recess 15 of the room 10.

[0026] As shown in Figure 2, the lower frame 22 has a lower frame lower panel portion 221 (lower panel) extending in the longitudinal direction of the lower frame 22, a lower rail 222 for the first shoji screen, a lower rail 223 for the second shoji screen, and a pair of rising pieces 224 (rising walls) at the front end.

[0027] The lower frame lower plate portion 221 is disposed on the lower portion of the lower frame 22, and is formed in a horizontal plate shape extending in the projection direction. The lower frame lower plate portion 221 is disposed on the bottom portion 151 of the floor recessed portion 15.

[0028] The first shoji lower rail 222 is erected upward from the lower frame lower panel portion 221 on the upper surface of the back side of the lower frame 22. A door roller 331 arranged at the lower end of the lower frame 33 of the first shoji 3 engages with the first shoji lower rail 222. This allows the first shoji 3 to slide left and right in the front direction within the frame body 2.

[0029] The second shoji lower rail 223 is erected upward from the lower frame lower panel portion 221 on the upper surface of the front side of the lower frame 22. A door roller 431 arranged at the lower end of the lower frame 43 of the second shoji 4 engages with the second shoji lower rail 223. This allows the second shoji 4 to slide left and right in the front direction within the frame body 2.

[0030] The pair of projection direction end rising pieces 224 rise from both ends in the projection direction of the lower frame lower panel portion 221. The projection direction end rising piece 224 is formed in an L shape that is open on the outside in the projection direction of the lower frame 22. The projection direction end rising piece 224 has a vertical plate portion 224a that is arranged along a pair of inner side surface portions 152 of the floor recess 15, and a protruding plate portion 224b that protrudes from the upper end of the vertical plate portion 224a to the outside in the projection direction of the lower frame 22 and is arranged along the upper surface 111 of the floor surface 11.

[0032] The left and right vertical frames 23 are disposed at the left and right ends of the frame body 2 as shown in Fig. 3, and extend in the up-down direction as shown in Fig. 1. The left and right vertical frames 23 are disposed along the left and right wall surfaces 12, respectively.

[0033] 3, the left and right vertical frames 23 each have a vertical frame projection direction extending plate 231, a front side inner protruding plate 232, a rear side inner protruding plate 233, a middle inner protruding plate 234, and a shoji end face abutting fin portion 235. The vertical frame projection direction extending plate 231, the front side inner protruding plate 232, the rear side inner protruding plate 233, the middle inner protruding plate 234, and the shoji end face abutting fin portion 235 extend over the entire longitudinal area of ​​the vertical frame 23.

[0034] 3, the vertical frame prospective direction extending plate 231 is formed in a plate shape extending a predetermined length in the prospective direction. The front side inner protruding plate 232 protrudes inward in the left and right direction of the prospective direction of the frame body 2 from the front end of the vertical frame prospective direction extending plate 231 in the prospective direction.

[0035] The rear inner protruding plate 233 protrudes inward in the left-right direction of the front direction of the frame body 2 from the rear end of the vertical frame front direction extending plate 231 in the front direction. The middle inner protruding plate 234 protrudes inward in the left-right direction of the front direction of the frame body 2 from the middle of the vertical frame front direction extending plate 231 in the front direction (depth direction). The shoji end face abutment fin portion 235 is provided on the inner surface of the vertical frame front direction extending plate 231 in the left-right direction of the front direction, at a portion where it abuts the end face of the first shoji screen 3 or the second shoji screen 4 on the door tip side in the left-right direction of the front direction.

[0036] The configurations of the upper corner portion 201 and the lower corner portion 202 of the frame body 2 will be described. As shown in Figures 4 and 5, the upper corner portion 201 is formed by combining a longitudinal end portion of the vertical frame 23 with a longitudinal end portion of the upper frame 21. The lower corner portion 202 is formed by combining a longitudinal end portion of the vertical frame 23 with a longitudinal end portion of the lower frame 22.

[0037] Here, in this embodiment, the upper frame 21 and the left and right vertical frames 23 are made of resin frames formed by extrusion molding of synthetic resin such as polyvinyl chloride resin. In the upper frame 21, as shown in FIG. 5, the first shoji upper frame downward protruding rail 212, the second shoji upper frame downward protruding rail 213, and the upper frame front side downward extension plate 214 are provided over the entire longitudinal area of ​​the upper frame 21, and no notch processing is performed. Similarly, in the vertical frame 23, the front side inner protruding plate 232, the rear side inner protruding plate 233, the middle inner protruding plate 234, and the shoji end surface abutting fin portion 235 are provided over the entire longitudinal area of ​​the vertical frame 23, and no notch processing is performed. The lower frame 22 is formed by extrusion molding of a metal such as aluminum material. In the bottom frame 22, the first shoji lower rail 222, the second shoji lower rail 223, and a pair of front end rising pieces 224 are provided over the entire longitudinal area of ​​the bottom frame 22, and no cutouts are provided.

[0038] First, a description will be given of the configuration of the upper corner portion 201 of the frame body 2. As shown in Fig. 4 and Fig. 5, in the upper corner portion 201, the longitudinal end portion of the upper frame 21 is disposed inside the longitudinal upper end portion of the vertical frame 23 in the projection direction.

[0039] 4, an upper seal member 24 is provided at the upper corner portion 201. The upper seal member 24 is disposed between the upper frame 21 and the vertical frame 23 at the upper corner portion 201, and functions as an airtight material. The upper seal member 24 is formed, for example, from a resin material having airtight properties.

[0040] The upper seal member 24 is disposed on the outside of the longitudinal end of the upper frame 21. As shown in Fig. 5, the upper seal member 24 is disposed along the end face 211a of the longitudinal end of the upper frame 21. The upper seal member 24 has a rod-shaped portion 241 extending in the prospective direction, a front-side downward protruding portion 242, a first shoji-side downward protruding portion 244, and a second shoji-side downward protruding portion 243.

[0041] The prospective direction extending rod-shaped portion 241 is formed in a rod shape extending in the prospective direction along the end face 211a of the longitudinal end of the upper frame 21. The front side downward protruding portion 242 protrudes downward from the prospective direction front side end of the prospective direction extending rod-shaped portion 241 along the end face of the longitudinal end of the upper frame front side downward extending plate 214 of the upper frame 21.

[0042] The first shoji side downward protrusion 244 protrudes downward from the front direction extending rod portion 241 along the end face of the longitudinal end of the first shoji upper frame downward protrusion rail 212 of the upper frame 21. The second shoji side downward protrusion 243 protrudes downward from the front direction extending rod portion 241 along the end face of the longitudinal end of the second shoji upper frame downward protrusion rail 213 of the upper frame 21.

[0043] In the upper corner portion 201 where the vertical frame 23 and the upper frame 21 are combined, with the upper seal member 24 arranged along the end face 211a of the longitudinal end of the upper frame 21, the longitudinal end of the upper frame 21 is arranged between the front inner protruding plate 232 and the rear inner protruding plate 233 of the vertical frame 23 in the projection direction. In the upper corner portion 201, the upper frame 21 and the vertical frame 23 are arranged in a so-called vertically-biased fit, with the longitudinal end of the upper frame 21 being arranged inside the vertical frame 23 in the projection direction.

[0044] Next, a description will be given of the configuration of the lower corner portion 202 of the frame body 2. As shown in Figures 4 and 5, in the lower corner portion 202, at least a part of the lower end portion of the vertical frame 23 is disposed inside the longitudinal end portion of the lower frame 22 in the projection direction.

[0045] 4 and 5, a lower seal member 25 is provided in the lower corner portion 202. The lower seal member 25 is disposed between the lower frame 22 and the vertical frame 23 in the lower corner portion 202, and functions as an airtight material. The lower seal member 25 is formed, for example, from a resin material having airtight properties.

[0046] 6 and 7, the lower seal member 25 is arranged side by side on the outside of the longitudinal end of the vertical frame 23. The lower seal member 25 is arranged along the end face 221a of the longitudinal end of the lower frame 22. The lower seal member 25 has a plate-shaped portion 251 extending in the projection direction, a first shoji side upward protruding portion 252, and a second shoji side upward protruding portion 253.

[0047] The projection-direction-extending plate-like portion 251 is formed in a long and narrow plate shape extending in the projection direction along the end surface 221a of the longitudinal end of the lower frame 22. The projection-direction-extending plate-like portion 251 has a predetermined width in the left-right direction of the projection direction and extends in the projection direction.

[0048] The first shoji side upward protrusion 252 protrudes upward from the upper surface 251a of the projection direction extending plate-like portion 251, on the side of the end face of the longitudinal end of the first shoji lower rail 222 of the lower frame 22. The first shoji side upward protrusion 252 is formed on the upper surface 251a of the projection direction extending plate-like portion 251 at a position extending the first shoji lower rail 222 outward in the longitudinal direction of the lower frame 22. The first shoji side upward protrusion 252 extends a predetermined length in the width direction (left-right direction of the lower frame 22) of the projection direction extending plate-like portion 251 from the end on the lower frame 22 side in the width direction to a position not reaching the end on the opposite side to the lower frame 22 in the width direction. On the upper surface 251a of the projection direction extending plate-shaped portion 251, the first shoji side upward protrusion 252 is not formed on the upper surface 251b of the end portion opposite the lower frame 22 in the width direction of the projection direction extending plate-shaped portion 251.

[0049] The second shoji side upward protrusion 253 protrudes upward from the upper surface 251a of the projection direction extending plate-shaped portion 251, on the side of the end face of the longitudinal end of the second shoji lower rail 223 of the lower frame 22. The second shoji side upward protrusion 253 is formed on the upper surface 251a of the projection direction extending plate-shaped portion 251 at a position extending the second shoji lower rail 223 outward in the longitudinal direction of the lower frame 22. The second shoji side upward protrusion 253 each extends a predetermined length in the width direction (left-right direction of the lower frame 22) of the projection direction extending plate-shaped portion 251 from the end on the lower frame 22 side in the width direction to a position not reaching the end on the opposite side to the lower frame 22 in the width direction. On the upper surface 251a of the projection direction extending plate-shaped portion 251, the second shoji side upward protrusion 253 is not formed on the upper surface 251b of the end portion opposite the lower frame 22 in the width direction of the projection direction extending plate-shaped portion 251.

[0050] When the vertical frame 23 is combined with the lower sealing member 25 arranged in a line on the longitudinal outside of the lower frame 22, the lower end portion of the vertical frame prospective direction extending plate 231 of the vertical frame 23 is positioned on the upper surface 251b of the end portion opposite the lower frame 22 in the width direction of the prospective direction extending plate-shaped portion 251.

[0051] In the lower corner portion 202, the lower seal members 25 are arranged side by side on the outside of the longitudinal end portion of the lower frame 22. The lower ends of the front inner protruding plate 232, the rear inner protruding plate 233, and the middle inner protruding plate 234 of the vertical frame 23 are arranged across the upper surface 221b of the lower frame lower plate portion 221 of the lower frame 22 and the upper surface 251a of the prospective direction extending plate portion 251 of the lower seal member 25, as shown in Fig. 4. The lower end of the vertical frame prospective direction extending plate 231 of the vertical frame 23 is arranged on the upper surface 251b of the prospective direction extending plate portion 251 of the lower seal member 25 on the outer end side in the longitudinal direction of the lower frame 22.

[0052] As a result, in the lower corner portion 202 where the vertical frame 23 and the lower frame 22 are combined, the lower end portion of the vertical frame 23 is positioned across the upper surface 221b of the lower frame lower panel portion 221 of the lower frame 22 and the upper surface 251a of the forward direction extending plate portion 251 of the lower sealing member 25.

[0053] In this way, in the lower corner portion 202, at least a part of the lower end portion of the vertical frame 23 is disposed on the upper surface 221b of the lower frame lower plate portion 221 of the lower frame 22. In the lower corner portion 202, at least a part of the lower end portion of the vertical frame 23 is disposed between a pair of projection direction end rising pieces 224 of the lower frame 22 on the upper surface 221b of the lower frame lower plate portion 221 of the lower frame 22, and is disposed on the inside of the projection direction of the lower frame 22, in a so-called horizontally-oriented fit.

[0054] Next, a case will be described where the vertical frame 23, the lower frame 22, and the lower sealing member 25 are combined and installed in the lower corner portion 202. First, as shown in Fig. 8, the lower sealing member 25 is accommodated in the floor recess 15 of the room 10. With the lower sealing member 25 accommodated in the floor recess 15, the end face of the projection direction extending plate-like portion 251 of the lower sealing member 25 facing the wall surface 12 is adhered and fixed to the wall surface 12 with an adhesive (not shown) such as double-sided tape.

[0055] Next, the lower frame 22 is accommodated in the floor recess 15 of the room 10, and the longitudinal end of the lower frame 22 accommodated in the floor recess 15 is abutted against the end face opposite the wall surface 12 of the forward-direction extending plate-shaped portion 251 of the lower sealing member 25.

[0056] 7, the lower end of the vertical frame 23 is disposed between a pair of projecting end rising pieces 224 of the lower frame 22 so as to straddle the upper surface 221b of the lower frame lower plate portion 221 of the lower frame 22 and the upper surface 251a of the projecting direction extending plate-like portion 251 of the lower seal member 25. In this way, in the lower corner portion 202, with the lower frame 22 disposed in the floor recess 15, the lower frame 22 and the vertical frame 23 can be combined and installed with a so-called horizontal fit.

[0057] According to this embodiment, the following effects are achieved: The partition window 1 of this embodiment divides the space inside the room, and includes a frame body 2 formed by framing an upper frame 21, a lower frame 22, and a pair of vertical frames 23, and a shoji (first shoji 3, second shoji 4) that is arranged inside the frame body 2 and has resin frames 31, 41 and glass 35, 45 arranged inside the frames 31, 41, the lower frame 22 is arranged in a floor recess 15 formed by recessing from the floor surface 11 inside the room, and in a lower corner portion 202 formed by combining the vertical frame 23 and the lower frame 22, at least a part of the lower end of the vertical frame 23 is arranged on an upper surface 221b of the lower frame 22.

[0058] Conventionally, in partition windows, if the bottom frame and the vertical frame are fitted in a so-called horizontally-dominated manner, the vertical line of the vertical frame is interrupted halfway at the lower corner, which makes the design look untidy, and therefore the partition window is sometimes fitted in a vertically-dominated manner from the viewpoint of design. In contrast, in the present disclosure, the bottom frame 22 of the frame body 2 is arranged in the floor recess 15 in the partition window 1, so that the design can be ensured even if the partition window is fitted in a so-called horizontally-dominated manner. Furthermore, since at least a part of the lower end of the vertical frame 23 is arranged on the upper surface 221b of the bottom frame lower panel portion 221 of the bottom frame 22, there is no need to cut out the ribs of the vertical frame 23. This reduces the processing cost of the frame.

[0059] In this embodiment, the lower seal members 25 are arranged side by side on the outer side of the lower frame 22 in the longitudinal direction, and the lower end portion of the vertical frame 23 is arranged straddling the upper surface 221b of the lower frame 22 and the upper surface 251a of the lower seal member 25. As a result, in a so-called horizontally extending configuration in which at least a part of the lower end portion of the vertical frame 23 is arranged on the upper surface 221b of the lower frame lower plate portion 221 of the lower frame 22, by arranging the lower end portion of the vertical frame 23 so as to straddle the upper surface 221b of the lower frame 22 and the upper surface 251a of the lower seal member 25, it is possible to improve airtightness performance.

[0060] In this embodiment, the lower frame 22 has a lower frame lower panel portion 221 extending in the longitudinal direction of the lower frame 22, and a pair of prospective end rising pieces 224 rising from both ends of the lower frame 22 in the prospective direction, the prospective end rising pieces 224 being arranged along the inner surface of the floor recess 15, and at least a portion of the lower end of the vertical frame 23 being arranged between the pair of prospective end rising pieces 224 on the upper surface 221b of the lower frame lower panel portion 221.

[0061] This allows the pair of projection direction end rising pieces 224 to be positioned along the inner side surface 152 of the floor recess 15, making it possible to easily install the bottom frame 22 in the floor recess 15. Also, at least a part of the lower end of the vertical frame 23 can be positioned between the pair of recess direction end rising pieces 224, so that the lower end of the vertical frame 23 can be accommodated inside the projection direction of the bottom frame 22 after the bottom frame 22 is accommodated inside the floor recess 15. This makes it difficult to see the bottom frame 22 and the vertical frame 23 from the outside, providing a neat appearance at the lower end of the partition window 1 and ensuring design.

[0062] The present disclosure is not limited to the above-described embodiments, and modifications and improvements within the scope of achieving the object of the present disclosure are included in the present disclosure. [Explanation of symbols]
