Description

[Technical Field]

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

[0002] Shoji screens in which the peripheral edge of a surface material such as glass is held by a frame have been known for some time (see, for example, Patent Document 1). This type of shoji screen has a water tray provided within the hollow portion (hollow section) of the upper frame, and an opening is provided on the wall surface on the outside of the hollow portion so that water from the water tray can enter the space above the sealing material and backup material that hold the glass. Rainwater and other water that enters the hollow portion of the upper frame flows from the water tray into a drain hole, is drained to the outside of the hollow portion, and is then discharged to the outside via the vertical frame and lower frame.

[0003] [Patent Document 1] Publication number 08-9432 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned conventional shoji screens are designed to allow rainwater to flow through the space in which the glass is held by the sealing material and backup material, which poses a problem that the rainwater flowing through the space in which the glass is held may overflow the sealing material and backup material and seep into the room.

[0005] The present invention has been made in view of such problems, and its purpose is to provide a shoji screen that is less likely to allow rainwater and other liquids that have entered the hollow portion of the upper frame to seep into the room. [Means for solving the problem]

[0006] The main invention for achieving this object is a shoji screen having a panel, and a frame body formed by assembling upper and lower frames and left and right vertical frames that accommodate the peripheral end of the panel, wherein the vertical frames have a vertical hollow portion penetrating in the up and down direction on the outer periphery of a vertical panel storage section that accommodates the side end of the panel, and a vertical frame recess board portion that separates the vertical panel storage section from the vertical hollow portion and to which the small end of the upper frame abuts and to which the upper frame is joined, and the upper frame has a horizontal hollow portion penetrating in the horizontal direction above the upper panel storage section that accommodates the upper end of the panel, and a vertical hollow portion that separates the upper panel storage section from the horizontal hollow portion and a partition plate portion that separates the upper surface material storage section from the horizontal hollow portion, wherein the partition plate portion has a cutout portion at the small edge that abuts the vertical frame projection plate portion, connecting the upper surface material storage section to the horizontal hollow portion, and the vertical frame projection plate portion has a connecting opening that connects the vertical surface material storage section to the vertical hollow portion, and one of the partition plate portion and the vertical frame projection plate portion has a guide portion that protrudes toward the upper surface material storage section or the vertical frame storage section, and guides water discharged from the cutout portion from the connecting opening to the vertical hollow portion. Other features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a shoji screen that is less likely to allow rainwater and other water that has entered the hollow portion of the upper frame to seep into the room. [Brief explanation of the drawings]

[0009] Hereinafter, a joint structure and fittings according to the present invention will be described with reference to the drawings. In this embodiment, as shown in Figures 1 and 2, for example, in a fitting 1 having a folding door 1a supported by a frame body 2, in which the joining parts of adjacent shoji screens are connected so that they can rotate and be folded, the shoji screen 3 that makes up the folding door 1a will be used as an example for explanation.

[0010] The fixture 1 of this embodiment has a rectangular frame body 2 consisting of an upper frame 2a, a lower frame 2b, and left and right vertical frames 2c, and two sets of folding doors 1a consisting of two shoji screens 3 connected in a foldable manner.

[0011] Each shoji screen 3 has a frame body 3a made up of an upper frame 30, a lower frame 40, and left and right vertical frames 50 assembled in a rectangular shape, and double-glazed glass 3b as a face material whose peripheral edges are housed and held in the frame body 3a. The upper frame 30, lower frame 40, and left and right vertical frames 50 are all composite frames made up of a resin frame made of extruded material located on the inside of the room, and a metal frame made of extruded material located on the outside of the room and engaged with the resin frame.

[0012] As shown in Figure 3, the upper frame 30 has an upper resin frame 31 arranged on the indoor side and an upper metal frame 32 arranged on the outdoor side. The upper metal frame 32 has a horizontal hollow section 32a that penetrates horizontally and has a substantially rectangular cross section, an upper partition plate section 32b that forms the horizontal hollow section 32a and separates the horizontal hollow section 32a from the space above it, a lower partition plate section 32c that forms the horizontal hollow section 32a and separates the horizontal hollow section 32a from the space below it, an upper exterior plate section 32d that connects the outdoor edges of the upper partition plate section 32b and the lower partition plate section 32c, and an upper interior plate section 32e that forms the horizontal hollow section 32a and faces the indoor side of the upper exterior plate section 32d with a gap in between.

[0013] The upper and lower parts of the upper interior panel 32e are provided with upper locking portions 32f, which lock onto the upper resin locking pieces 31a provided on the upper resin frame 31. The upper metal frame 32 is connected to the upper exterior panel 32d and has a downward extension 32g extending downward from the lower partition panel 32c. Together with the upper resin extension 31b extending downward from the lower partition panel 32c in the upper resin frame 31 locked to the upper locking portion 32f, this forms the upper surface material accommodating portion 30a that accommodates the upper end of the double-glazed glass 3b. In other words, the lower partition panel 32c corresponds to a partition panel that separates the horizontal hollow portion 32a and the upper surface material accommodating portion 30a. The upper end of the double-glazed glass 3b is accommodated and held in the upper surface material accommodating portion 30a via a gasket 4.

[0014] The vertical resin frames 51 and vertical metal frames 52 that make up the left and right vertical frames 50 joined to both ends of the upper frame 30 are made of the same extruded profile material, but with the left and right reversed. The vertical metal frame 52 has a vertical hollow portion 52a that penetrates vertically and has a substantially rectangular cross section, an inner peripheral partition plate portion 52b that forms the vertical hollow portion 52a and separates the vertical hollow portion 52a from the space on its inner periphery, an outer peripheral partition plate portion 52c that forms the vertical hollow portion 52a and separates the vertical hollow portion 52a from the space on its outer periphery, a vertical outer panel portion 52d that connects the outer edges of the inner peripheral partition plate portion 52b and the outer peripheral partition plate portion 52c, and a vertical indoor panel portion 52e that forms the vertical hollow portion 52a and faces the indoor side of the vertical outer panel portion 52d with a gap between them.

[0015] Vertical interior panel 52e has vertical locking portions 52f on the inner and outer peripheral portions of frame 3a to lock onto vertical resin locking pieces 51a provided on vertical resin frame 51. Vertical metal frame 52 is connected to vertical exterior panel 52d and has inner peripheral extension 52g extending inward from inner peripheral partition panel 52c. Together with vertical resin extension 51b extending inward from inner peripheral partition panel 52c in vertical resin frame 51 locked to vertical locking portion 52f, vertical panel material housing 50a is formed to house the side edge of double-glazed glass 3b. The side edge of double-glazed glass 3b is housed and held in vertical panel material housing 50a via gasket 4.

[0016] The upper frame 30 has both ends accommodated in the vertical panel accommodating sections 50a of the left and right vertical frames 50 and joined to the vertical frames 50. The ends 30b at both ends of the upper frame 30 are joined by abutting against an inner peripheral partition plate section 52b that forms a projected surface in the vertical metal frame 52 and a projected wall section 51c that forms a projected surface connected to the inner peripheral partition plate section 52b in the vertical resin frame 51.

[0017] At this time, the ends of the upper partition plate portion 32b and the lower partition plate portion 32c of the upper metal frame 32 abut against the inner partition plate portion 52b of the vertical metal frame 52, and are joined by screws that penetrate the inner partition plate portion 52b from the outer periphery and screw into the threaded portion 32h of the upper metal frame 32. Here, the inner partition plate portion 52b separates the vertical panel accommodating portion 50a and the vertical hollow portion 52a, and corresponds to the vertical frame projection plate portion against which the end 30b of the upper frame 30 abuts and to which the upper frame 30 is joined.

[0018] 5, upper partition plate portion 32b of upper frame 30 has upper cutout portions 32i at both ends, and upper cutout portions 32i allow the space above upper partition plate portion 32b to communicate with horizontal hollow portion 32a when end 30b of upper frame 30 is in contact with vertical frame 50. Also, lower partition plate portion 32c has lower cutout portions 32j at both ends, and lower cutout portions 32j allow the horizontal hollow portion 32a to communicate with upper surface material accommodating portion 30a when end 30b of upper frame 30 is in contact with vertical frame 50.

[0019] In the vertical frame 50, a communicating opening 52i connecting the vertical panel material storage section 50a and the vertical hollow section 52a, and a guide section 52j bent up from the lower end of the communicating opening 52i toward the vertical panel material storage section 50a are provided on the inner partition plate section 52b, which abuts the end of the lower partition plate section 32c. The guide section 52j is separated from the upper edge where the communicating opening 52i is formed in the inner partition plate section 52b and the outside and inside edges in the projection direction, and the section corresponding to the lower edge of the communicating opening 52i is connected, with the section above the position that would become the lower edge of the communicating opening 52i bent up toward the vertical panel material storage section 50a.

[0020] The upper surface of the guide portion 52j is seamlessly connected to the inner surface of the vertical hollow portion 52a of the inner partition plate portion 52b. The guide portion 52j has a slope that gradually increases in height from the portion corresponding to the lower edge of the communication opening 52i toward the bent tip 52k. In other words, the guide portion 52j has a slope that increases in height in the direction away from the inner partition plate portion 52b.

[0021] When the upper frame 30 and the vertical frame 50 are joined, as shown in Figure 6, the tip 52k of the guide portion 52j of the vertical frame 50 is located within the lower cutout portion 32j of the upper frame 30 and is in contact with or close to the edge 32k along the projection direction of the lower cutout portion 32j. Therefore, the horizontal hollow portion 32a of the upper frame 30 and the vertical hollow portion 52a of the vertical frame 50 are in communication.

[0022] As shown in Figure 7, in the shoji screen 3, rainwater and other water that has entered onto the upper partition plate portion 32b of the upper frame 30 enters through the upper cutout portion 32i of the upper partition plate portion 32b onto the lower partition plate portion 32c of the horizontal hollow portion 32a, and rainwater and other water that has entered onto the lower partition plate portion 32c passes through the lower cutout portion 32j of the lower partition plate portion 32c, along the guide portion 52j, and enters the vertical hollow portion 52a through the communicating opening 52i.

[0023] According to the shoji screen 3 of this embodiment, rainwater and the like that has entered the horizontal hollow portion 32a of the upper frame 30 enters below the lower partition plate portion 32c through the lower cutout portion 32j of the lower partition plate portion 32c that separates the upper surface material storage portion 30a and the horizontal hollow portion 32a. At this time, the water is guided into the vertical hollow portion 52a through the communication opening 52i that connects the vertical surface material storage portion 50a and the vertical hollow portion 52a by the guide portion 52j that protrudes from the vertical frame projection plate portion 52b of the vertical frame 50 toward the vertical surface material storage portion 50a. For this reason, rainwater is less likely to enter the upper surface material storage section 30a of the upper frame 30 and the vertical surface material storage section 50a of the vertical frame 50, making it possible to prevent rainwater and the like that has entered the horizontal hollow section 32a of the upper frame 30 from seeping into the room from the upper surface material storage section 30a and the vertical surface material storage section 50a.

[0024] Furthermore, since the guide portion 52j is inclined so that it becomes higher in the direction away from the vertical frame projection plate portion 52b, rainwater and the like that flows out onto the guide portion 52j can flow over the guide portion 52j toward the communicating opening 52i and be quickly discharged into the vertical hollow portion 52a.

[0025] Furthermore, if the protruding tip 52k of the guide portion 52j is configured to be at the same height as the lower partition plate portion 32c or higher than the lower partition plate portion 32c, for example, even if the upper frame 30 and the lower frame 40 are formed from the same extruded section material but are differently processed, unless the lower frame 40 has a lower cutout portion 32j like the upper frame 30, the lower frame 40 and the guide portion 52j will interfere with each other and the lower frame 40 will not be able to be attached to the position of the upper frame 30. This makes it possible to prevent mistakes in attaching the upper frame 30 and the lower frame 40.

[0026] Furthermore, because the edge 32k of the lower cutout 32j and the protruding tip 52k of the guide 52j are in contact with or close to each other, rainwater that enters the guide 52j is less likely to leak out between the edge 32k of the lower cutout 32j and the tip 52k of the guide 52j, which makes it possible to more reliably drain rainwater and the like into the vertical hollow 52a.

[0027] In the above embodiment, an example in which the guide portion 52j is provided on the vertical frame 50 has been described, but this is not limiting. For example, a guide portion may be provided in the lower cutout portion 32j of the lower partition plate portion 32c of the upper frame 30, protruding from the edge 32k of the lower cutout portion 32j toward the upper surface material storage portion 30a. In this case, the upper surface of the guide portion is seamlessly connected to the inner surface of the horizontal hollow portion 32a of the lower partition plate portion 32c, and has a slope that gradually decreases in height toward the tip.

[0028] When the upper frame 30 and the vertical frame 50 are joined, the tip of the guide portion of the upper frame 30 is located within the communication opening 52i provided in the inner peripheral partition plate portion 52b of the vertical frame 50, and is in contact with or close to the lower edge of the communication opening 52i. Therefore, the horizontal hollow portion 32a of the upper frame 30 and the vertical hollow portion 52a of the vertical frame 50 are in communication. Then, rainwater and the like that has entered onto the upper partition plate portion 32b of the upper frame 30 flows from the upper cutout portion 32i of the upper partition plate portion 32b, along the guide portion, into the communication opening 52i and then into the vertical hollow portion 52a.

[0029] In the above embodiment, the shoji screen 3 constituting the folding door 1a has been described as an example of a shoji screen according to the present invention, but the present invention is not limited to this. For example, the shoji screen may be a sliding door or a swing door, and may be a shoji screen having a frame body and a face material. Furthermore, in the above embodiment, an example has been described in which the frame body 3a is a composite frame having a resin frame and a metal frame, but it may be either a resin frame or a metal frame. Furthermore, although composite glass has been described as an example of a face material, the present invention is not limited to this. For example, single-pane glass or a resin plate material may also be used.

[0030] The above-described embodiment is intended to facilitate understanding of the present invention, and is not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and it goes without saying that the present invention includes equivalents thereof. The present embodiment includes at least the following inventions:

[0031] (Aspect 1) A shoji screen having a panel and a frame body formed by assembling upper and lower frames and left and right vertical frames that accommodate the peripheral end of the panel, wherein the vertical frames have a vertical hollow portion penetrating in the up and down direction on the outer periphery of the vertical panel storage section that accommodates the side end of the panel, and a vertical frame projection board portion that separates the vertical panel storage section and the vertical hollow portion and to which the small end of the upper frame abuts to join the upper frame, and the upper frame has a horizontal hollow portion penetrating in the horizontal direction above the upper panel storage section that accommodates the upper end of the panel, and a vertical hollow portion that separates the upper panel storage section and the horizontal hollow portion a partition plate portion having a notch portion at the edge that abuts against the vertical frame projection plate portion, which connects the upper surface material storage portion to the horizontal hollow portion; the vertical frame projection plate portion having a communicating opening that connects the vertical surface material storage portion to the vertical hollow portion; and one of the partition plate portion and the vertical frame projection plate portion having a guide portion that protrudes toward the upper surface material storage portion or the vertical frame projection plate portion and guides water discharged from the notch portion from the communicating opening to the vertical hollow portion.

[0032] According to the shoji screen of aspect 1, when rainwater or the like that has entered the horizontal hollow portion of the upper frame flows out below the partition plate from the cutout portion of the partition plate that separates the upper surface material storage portion and the horizontal hollow portion, it is guided into the vertical hollow portion from the communicating opening that connects the vertical surface material storage portion and the vertical hollow portion by a guide portion that protrudes from one of the partition plate and the vertical frame projection plate toward the upper surface material storage portion or the vertical surface material storage portion. Therefore, rainwater is less likely to enter the upper surface material storage portion of the upper frame and the vertical surface material storage portion of the vertical frame, making it possible to prevent rainwater or the like that has entered the horizontal hollow portion of the upper frame from seeping into the room from the upper surface material storage portion and the vertical surface material storage portion.

[0033] (Aspect 2) A shoji screen according to aspect 2 is characterized in that the guide portion has a slope that increases in the direction away from the vertical frame projection board portion.

[0034] According to the shoji screen of aspect 2, the guide portion is inclined so that it becomes higher in the direction away from the vertical frame projection board portion, so that rainwater and the like that flows onto the guide portion can flow down the guide portion toward the communicating opening and be quickly discharged into the vertical hollow portion.

[0035] (Aspect 3) The shoji screen according to aspect 1 or aspect 2 is characterized in that the guide portion is provided in the vertical frame projection board portion.

[0036] According to the shoji screen of aspect 3, the guide portion is provided in the vertical frame projection board portion in which the communicating opening is provided, so that water that reaches the guide portion can be reliably discharged from the communicating opening through the vertical hollow portion.

[0037] (Aspect 4) A shoji screen according to aspect 3 is characterized in that the protruding tip of the guide portion is positioned at the same height as the partition plate portion or above the partition plate portion.

[0038] According to the shoji screen of the fourth aspect, the protruding tip of the guide is located at the same height as the partition board or above the partition board, so even if the upper and lower frames are made from the same extruded material but are differently processed, unless a notch is provided in the lower frame, the lower frame and the guide will interfere with each other and the frame will not be able to be attached to the upper frame. This makes it possible to prevent mistakes in attaching the upper and lower frames.

[0039] (Aspect 5) The shoji screen according to aspect 3 is characterized in that the edge of the cutout portion and the protruding tip of the guide portion are in contact with or close to each other.

[0040] According to the shoji screen of the fifth aspect, the edge of the notch and the protruding tip of the guide part are in contact with or close to each other, so rainwater and other water that enters the guide part is less likely to leak out between the edge of the notch and the tip of the guide part. This makes it possible for rainwater and other water to be more reliably discharged into the vertical hollow part. [Explanation of symbols]
