Description

  The present invention relates to a sliding window sash in which a plurality of sliding door shojis are slidably held inside a window frame.

  In general, the sliding window sash is slidably held by two sliding door sashes. However, in the conventional sliding window sash, the sliding window sash is not attached to the bottom frame of the window frame when the sliding window sash is closed. It has a structure in which no gap occurs between them. That is, smoke return is formed at the summing part of the adjacent shojis, and when the doors are closed, the smoke return of both shojis is engaged to ensure airtightness. However, there is a gap between the lower end of the smoke return and the upper surface of the lower frame, and wind and rain may enter from here. For this reason, an airtight piece is arranged in the central part of the guide rails of the two shojis, and the airtight piece covers the gap. As a result, the smoke return and the airtight piece block the gap formed between the lower end of the summing portion of the two shojis and the upper surface of the lower frame, so that ingress of wind and rain is prevented.

  In addition, when a resident becomes elderly or has to use a wheelchair due to an accident or illness, a general sash is known to be barrier-free. This is to place and fix an attachment of the same height between the guide rails of the shoji. According to this, since the step due to the guide rail is buried on the lower frame by the attachment, the caster of the wheelchair can smoothly cross the lower frame without falling between the guide rails.

  However, since the barrier-free attachment is arranged at a position where it interferes with the lower arm of the inner or outer obstacle, the obstacle on the interference side cannot be opened. Therefore, this shoji is FIX, and the sash must be opened and closed only by operating the other shoji, which is inconvenient and inconvenient.

  An object of the present invention is to solve the above problems and to provide a sliding window sash that can be changed to a barrier-free specification, and that can open and close all the shojis even after the change.

  In order to solve the above-mentioned problem, the invention according to claim 1 is configured such that a window frame is rectangularly framed from upper and lower frames and left and right vertical frames, and a plurality of rails for slidably guiding a shoji to the lower frame are mutually connected. In the sliding window sash that is parallel and provided with the same level of horizontal level, a protrusion is formed along the longitudinal direction on the opposing surface of the adjacent rail, and the above-mentioned shoji is between the adjacent rails. An airtight piece is arranged in a part corresponding to the summoning part of the above, and the rail and the rail-to-rail attachment with the rail part having the same level of the horizontal level are arranged on both sides of the airtight piece, and the above Adjacent shojis with airtight pieces and rail-to-rail attachments detachably provided on the above-mentioned ridges, with the expected size of the lower part of the lower arm of the shoji being reduced, and the lower end of the smoke return of each shoji being cut out Characterized in that the formation of the space portion does not interfere with the rail portion of the rail between the attachments.

  The invention according to claim 2 is characterized in that, in claim 1, an end of the window frame of the attachment between rails on the vertical frame side is fixed to the lower frame via an end cap.

  According to the first aspect of the present invention, the airtight piece and the attachment between the rails are detachably provided on the protrusions formed along the longitudinal direction of the opposing surfaces of the adjacent rails. When there is no attachment, it can be used as a general sash, and when the rail-to-rail attachment is attached, the rail part has approximately the same level as the shoji guide rail, and the gap between the rails is narrowed. For example, when moving with a wheelchair, it can move smoothly, and the caster does not fall between the rails, so that a barrier-free sash can be obtained. Thus, since the rail-to-rail attachment can be easily attached to and detached from the completed shoji guide rail, it can be easily changed to a general sash or a barrier-free sash.

  In addition, between the adjacent guide rails, an airtight piece is arranged at a part corresponding to the summing part of the shoji, and an attachment between the rails is arranged on both sides of the airtight piece. Attaching the attachment to the ridge, reducing the expected size of the lower part of the lower arm of the shoji, and notching the lower end of the smoke return of each shoji, and the rail portion of the inter-rail attachment between adjacent shoji Since the space that does not interfere is formed, the airtight piece keeps the airtightness between the adjacent shojis when the sash is closed, and the attachment between the rails does not interfere with the opening and closing of the shoji. After that, the shoji can be opened and closed freely as before.

  According to the invention according to claim 2, since the end of the window frame of the attachment between the rails on the vertical frame side is fixed to the lower frame via the end cap, the attachment between the rails is shaken due to vibration or the like in a strong wind. There will be no stability.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

  1 is a front view of a sliding window sash, FIG. 2 is a cross-sectional view taken along line XX of FIG. 1, and FIG. 3 is a cross-sectional view taken along line YY of FIG.

  In the above figure, reference numeral 1 denotes a window frame. The window frame 1 is formed by rectangularly framing an upper frame 1a and a lower frame 1b made of an extruded aluminum material, and left and right vertical frames 1c and 1d. Rail 2a, intermediate rail 3a, and outer rail 4a are provided in parallel to each other. Similarly, an inner rail 2b, an intermediate rail 3b, and an outer rail 4b are provided in parallel to each other on the lower frame 1b from the indoor side to the outdoor side as rails for shoji guidance. The upper rails 2a, 3a, and 4a and the lower rails 2b, 3b, and 4b are arranged at positions corresponding to the upper and lower sides, and the rails extend over the entire length of the upper and lower frames 1a and 1b. It is formed to be. In addition, two screen door rails 5a and 5b are formed on the upper and lower frames 1a and 1b on the outdoor side of the outer rail.

  Further, an inner shoji 7, an intermediate shoji 8 and an outer shoji 9 are slidably guided by inner rails 2a and 3a and intermediate rails 3b and 3b and outer rails 3a and 3b of the upper and lower frames 1a and 1b, respectively. . As shown in FIG. 4, the inner rail 2b, the intermediate rail 3b, and the outer rail 4b of the lower frame 1b support the inner door 7, the intermediate door 8 and the outer door 9 so that they can roll freely. The inner rail 2 a, the intermediate rail 3 a, and the outer rail 4 a of the upper frame 1 a are engaged with a sliding groove 11 formed at the upper end of the inner shoji 7, the intermediate shoji 8, and the outer shoji 9. Thereby, the inner shoji 7, the intermediate shoji 8, and the outer shoji 9 can be opened and closed along the corresponding rails. As shown in FIG. 5, smoke folds 12 and 13 are formed on the vertical fence 29 of the summing part a of the inner shoji 7 and the intermediate shoji 8 and between the inner shoji 8 and the outer shoji 9 and are engaged with each other when closed. It is formed to match. A screen door 35 is slidably guided on the screen door rails 5a and 5b.

  In addition, as shown in FIG. 4, it forms so that the inner side side lower part 14a of each lower heel 14 of the inner shoji 7, the intermediate shoji 8, and the outer shoji 9 may go inside, and the estimated dimension of the lower part of each lower heel 14 Is formed to be small. Moreover, as shown in FIG.6 (c), the smoke return 12 formed in each summing part a (refer FIG. 3) of the intermediate shoji 8 and the external shoji 9 (the inner shoji 7 and the intermediate shoji 8 are also the same). The lower end 12 a is cut out at a position higher than the other smoke return 13. The smoke return 13 is the same as the conventional one. Thereby, the gap | interval between the lower arm 14 of each shoji 7,8 and shoji 8,9 is comparatively wide compared with the past.

  Next, the rail attachment 15 is configured to be attached between the outer rail 4b and the intermediate rail 3b of the lower frame 1b and between the intermediate rail 3b and the inner rail 2b. That is, as shown in FIG. 4 and FIG. 6C, the protrusions 19 are formed to face the side surfaces of the outer rail 4b, the intermediate rail 3b, and the inner rail 2b along the longitudinal direction thereof.

  On the other hand, as shown in FIG. 7, the rail-to-rail attachment 15 has a width that is approximately the same as the dimension between the rails, and is a step having an expected width that is substantially the same as or slightly shorter than the dimension between the vertical frames 1c and 1d on both sides. A rail portion 17 is formed so as to protrude from the center of the plate 16 along the longitudinal direction. A locking groove 18 is formed on the outdoor side of the step plate 16, and the center and side end portions are formed on the lower side on the indoor side. Projection pieces 20 and 21 are formed. The stepped plate 16 has a plurality of vent holes. When mounting the inter-rail attachment 15 on the lower frame 1b, as shown in FIG. 8, the locking groove 18 on the outdoor side of the stepped plate 16 is fitted to the protrusion 19 on the outdoor side of the outer rail 4b or the intermediate rail 3b. Then, the indoor end of the stepped plate 16 may be mounted by placing it on the indoor ridges 19 of the intermediate rail 3b and the inner rail 2b. As shown in FIG. 4, the height of the rail portion 17 in the mounted state is set to be the same height as the other rails 2a, 2b, and 2c at the horizontal level.

  Next, as shown in FIG. 9, an airtight piece 22 is arranged and fixed at each summing portion a of the inner shoji 7 and the intermediate shoji 8 and between the inner shoji 8 and the outer shoji 9 of the lower frame 1 b to close the sash. It is formed so as to close the gap between the lower lids 14 of the adjacent shojis.

  As shown in FIG. 10, the airtight piece 22 has the same width and the same height as the rail portion 17 of the rail-to-rail attachment 15 at the center upper part of the synthetic resin block-shaped main body 23 having the same width as the rail-to-rail attachment 15. A rail corresponding portion 24 is formed, and a plurality of fin-like airtight pieces 25 are provided side by side on the upper surface of the block-shaped main body 23 and around the rail corresponding portion 24. Then, as shown in FIG. 6B, the airtight piece 22 has fitting grooves 34 formed on both side surfaces of the block-shaped main body 23 at predetermined positions of the lower frame 1b, the outer rail 4b, the intermediate rail 3b, and The intermediate rail 3b and the inner rail 2b are attached by being fitted to protrusions 19 formed on opposite sides. Thereby, the lower frame structure becomes as shown in FIGS. 4 and 6A.

  Since the attachment 15 between the rails and the airtight piece 22 are provided on the same protrusion 19 in the same space between the rails, after the airtight piece 22 is attached to a predetermined position, as shown in FIGS. What is necessary is just to attach the attachment 15 between rails to the both sides of 22 in the above-mentioned way. At this time, one end of the inter-rail attachment 15 abuts on the rail corresponding portion 24 of the airtight piece 22 integrally. The other end is dimensioned so that there is enough space to attach the end cap 26 shown below.

  The other end of the inter-rail attachment 15, that is, the end of the window frame 1 on the vertical frame 1 c side is fixed by an end cap 26. As shown in FIG. 13, the end cap 26 has a rail presser 28 protruding from the center upper portion of the base plate portion 27, a protruding piece presser 30 formed below the rail presser 28, and both sides of the lower portion of the base plate portion 27. A J-shaped locking piece 31 is formed, and the end surfaces of the rail retainer 28 and the substrate portion 27 can be fitted to the rail portion 17 of the inter-rail attachment 15 and can be engaged with the upper surface of the stepped plate 16. A protruding edge portion 32 is formed. A notch 33 for avoiding interference with the protruding piece 36 formed inside the vertical frame 1c in the attached state is formed on the opposite side of the protruding edge portion 32 of the substrate portion 27.

  The end cap 26 configured as described above, after attaching the inter-rail attachment 15 between the rails, presses the locking piece 31 downward and presses it downward from above as shown in FIG. Thereby, the locking piece 31 is elastically locked and fixed to the opposing protrusion 19 of the outer rail 4b and the intermediate rail 3b and the opposing protrusion 19 of the intermediate rail 3b and the inner rail 2b. At this time, the rail portion 17 of the rail-to-rail attachment 15 is fitted between the protruding edge portions 32 of the rail retainer 28, the upper portion of the stepped plate 16 is pressed into the protruding edge portion 32 of the board portion 27, and the protruding piece 20 is It elastically abuts against the projecting piece presser 30. Therefore, since the rail-to-rail attachment 15 is fixed by the end cap 26, the rail-to-rail attachment 15 does not rattle due to vibrations or the like during strong winds, and stability is ensured.

  As described above, the expected size of the lower part of each lower arm 14 of the inner shoji 7, the intermediate shoji 8, and the outer shoji 9 is formed to be small. For this reason, the space | interval between the adjacent shojis 7 and 8 and the lower armpit of the shojis 8 and 9 is wide. Also, smoke smokers 12 and 13 formed in the summing portions a of the inner shoji 7 and the intermediate shoji 8 and the intermediate shoji 8 and the outer shoji 9 are cut out so as not to interfere with the rail portion of the inter-rail attachment 15. . As a result, as shown in FIG. 6A, the rail portion 17 of the inter-rail attachment 15 is passed between the adjacent lower side surfaces of the lower arm 14 of each shoji, and the airtight piece 25 of the airtight piece 22 is touched. A space is formed.

  Note that when the airtight piece 22 is replaced when necessary for repair or the like, the airtight piece 22 has elasticity, so that it can be easily attached and detached. Remove it and install a new one. Further, when replacing the attachment 15 between the rails, the shoji 7, 8, 9 and the airtight piece 22 are removed, and then the end on the airtight piece 22 side of the attachment between the rails 15 is lifted, and the other end is the end cap 26. So it can be easily removed. The new inter-rail attachment 15 may be attached so that one end thereof is in contact with the end cap 26 and the other end is in contact with the end of the airtight piece 22, and a shoji is attached.

  According to the above configuration, as shown in FIG. 4, the rail portion 17 of the inter-rail attachment 15 is arranged between the outer rail 4b and the intermediate rail 3b and between the intermediate rail 3b and the inner rail 2b, Since the gap between the rail 3b and the inner rail 2b is narrow, the height is the same. For example, when moving with a wheelchair, it can move smoothly and the caster does not fall between the rails. It can be changed to a free compatible sash.

  Moreover, since the inter-rail attachment 15 can be easily attached and detached between the completed shoji guide rails, it can be easily changed to a general sash or a barrier-free sash.

  Further, the expected size of the lower part of each lower collar 14 of the inner shoji 7, the intermediate shoji 8, and the outer shoji 9 is formed to be small. For this reason, the space | interval (width | variety) between the lower pallets 14 of the conventional shoji is large between the adjacent lower side surfaces of the lower pallet 14 of each shoji. Moreover, the lower end 12a of the smoke return 12 formed in each summing part a of the inner shoji 7 and the intermediate shoji 8 and the intermediate shoji 8 and the outer shoji 9 is cut off above the lower end of the lower arm 14 of each shoji. . For this reason, the space | interval (height) between the lower frame 1b and the smoke return 12 is also large. Therefore, a space portion that does not interfere with the rail portion 17 of the rail-to-rail attachment 15 and touches the airtight piece 25 of the airtight piece 22 is formed between the lower lids 14 of each shoji. Thereby, airtightness between the adjacent shojis is maintained by the airtight piece 22 when the sash is closed, and the attachment 15 between the rails does not obstruct the opening / closing traveling of the inner shoji 7, the intermediate shoji 8, and the outer shoji 9. Even after the attachment 15 between the rails is attached, the shoji can freely slide in the opening and closing direction as before the attachment.

  In addition, the said lower frame structure is not limited to the above-mentioned form. For example, as shown in FIG. 15 and FIG. 16, in the case of a heat insulating shoji having a configuration in which a portion facing each indoor side of the inner shoji 7, intermediate shoji 8 and outer shoji 9 is covered with a synthetic resin eaves member 37. The same barrier-free lower frame structure as described above can be applied. In addition, even in the heat insulating sash that improves the heat insulating property by covering the portion facing the indoor side of the window frame with the synthetic resin frame member 38, by shortening the length of the inter-rail attachment 15 by the thickness of the frame member 38, It can cope with barrier-free.

  Moreover, although the above-mentioned form is a three-piece sliding window sash, it can be similarly handled by a two-drawing window sash.
