Description

[Technical field]

[0001] The present disclosure relates to building materials. [Background technology]

[0002] Conventionally, a fitting is known that includes a frame body, an outer screen and an inner screen arranged within the frame body, and a windstop member provided on the underside of the upper frame (see, for example, Patent Document 1). The windstop member is provided on the upper part of the joint between the outer screen and the inner screen, in a portion of the underside of the upper frame through which the outer screen and the inner screen pass.

[0003] The windstop member is made of multiple resin fins (plate-shaped materials) that are thick in the direction of movement of the outer and inner screens and are arranged at intervals in the direction of movement of the outer and inner screens. The multiple fins of the windstop member have slit-like cuts that run from midway up and down to the bottom end to make it easier for the outer and inner screens to pass through when they are opened and closed. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2018-28247 A Summary of the Invention [Problem to be solved by the invention]

[0005] The multiple fins of the windstop member are easily knocked down or turned up by the outer and inner screens through the slits when the outer and inner screens move. Therefore, the slits in the fins may cause air leakage, which may affect the airtightness of the windstop member. Therefore, a windstop member that can suppress the deterioration of the airtightness is required.

[0006] The present disclosure aims to provide a fixture equipped with a wind-stopping member that can suppress a decrease in airtightness performance. [Means for solving the problem]

[0007] The present disclosure relates to a fitting comprising a frame body having an upper frame, an outer screen and an inner screen arranged so as to be movable laterally within the frame body, and a wind-stop member arranged on the underside of the upper frame above the joint between the outer screen and the inner screen in a portion through which the outer screen and the inner screen pass, wherein the wind-stop member has a resin plate-like material that extends in the indoor / outdoor directions and in the vertical direction and is formed with a thickness in the direction of movement of the outer screen and the inner screen, and the plate-like material has a cuttable line formed thereon that extends in the vertical direction to the lower end and is uncut when not in use and that will be cut when the outer screen or the inner screen passes through.

In this specification, the "visible direction" means the surface direction of the face materials 35, 45 of the sliding window 1 placed in an opening formed in the wall of a building, and the "visible direction" means the thickness direction (i.e., the depth direction) of the face materials 35, 45. The "visible direction" is also the indoor / outdoor direction. The "visible surface" means each surface of the sliding window 1 facing the outdoor side and the indoor side, and the "visible surface" means the surface of the sliding window 1 extending in the indoor / outdoor direction. In the drawings, the outdoor side of the sliding window 1 is the outdoor side X1, and the indoor side of the sliding window 1 is the indoor side X2.

[0010] As shown in Figures 1 to 3, the sliding window 1 is composed of a frame 2 attached to an opening in a building frame (not shown), and two screens, an outer screen 3 placed on the outside X1 and an inner screen 4 placed on the inside X2, fitted inside the frame 2, as well as one screen 51 placed on the outside X1 of the outer screen 3. The outer screen 3 and inner screen 4 can slide left and right (horizontally) within the frame 2 in the front direction.

[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. As shown in Fig. 2, the upper frame 21 is provided with an exterior rail 211 (downwardly protruding rail) and an interior rail 212 (downwardly protruding rail). The upper frame 21 has a screen rail 213 on the exterior side X1 of the exterior rail 211. The exterior rail 211 is formed to protrude downward from the upper frame 21 at the exterior side X1 of the upper frame 21, and guides the upper end of the outer screen 3. The interior rail 212 is formed to protrude downward from the upper frame 21 at the interior side X2 of the upper frame 21, and guides the upper end of the inner screen 4.

[0012] The lower frame 22 is provided with an exterior rail 221 and an interior rail 222. The lower frame 22 has a screen rail 223 on the exterior side X1 of the exterior rail 221.

[0013] The screen door 51 is engaged with the screen door rails 213, 223 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction.

[0014] The configuration of the frame 2 will be described in further detail. As shown in Fig. 2, the upper frame 21 has a composite structure in which resin cover materials 215, 216 are attached to the inner surface of a metal frame 214, which is the frame main body. Therefore, it has excellent heat insulation and moisture resistance.

[0015] The resin cover material 215 is disposed between the outdoor side rail 211 and the indoor side rail 212 of the upper frame 21. The resin cover material 216 is configured to include the indoor side X2 portion of the indoor side rail 212 of the upper frame 21, and is provided from the indoor side X2 surface of the indoor side rail 212 to the inner surface of the metal frame body 214.

[0016] As shown in Figures 1, 2, 4 and 5, a windstop member 6 is provided on the underside of the upper frame 21. The windstop member 6 is provided on the underside of the upper frame 21, above the joining portion 10 of the outer screen 3 and the inner screen 4. The windstop member 6 is disposed on the underside of the upper frame 21 above the joining portion 10 of the outer screen 3 and the inner screen 4, in a portion where the outer screen 3 and the inner screen 4 pass through. Details of the windstop member 6 will be described later.

[0017] As shown in Fig. 2, the lower frame 22 has a composite structure in which resin cover materials 226, 227 are attached to the inner surface of the metal frame body 224, which is the frame body main body. Therefore, it has excellent heat insulation and moisture resistance. The metal frame body 224 is divided into an outdoor metal frame body 2241 and an indoor metal frame body 2242 between the outdoor rail 221 and the indoor rail 222. The outdoor metal frame body 2241 and the indoor metal frame body 2242 are connected by a resin connecting material 2243.

[0018] As shown in Fig. 3, the vertical frame 23 arranged on the door end side of the outer sash 3 has a composite structure in which a resin cover material 232 is attached to the inner surface of the metal frame body 231, which is the frame body main body. Therefore, it has excellent heat insulation and moisture resistance. The resin cover material 232 is arranged on the inner surface of the vertical frame 23, closer to the room side X2 than the outer sash 3 in the closed state.

[0019] As shown in Fig. 3, the vertical frame 24 arranged on the door end side of the inner shoji screen 4 has a composite structure in which a resin cover material 242 is attached to the inner surface of a metal frame body 241, which is the frame body main body. Therefore, it has excellent heat insulation and moisture prevention properties. The resin cover material 242 is arranged on the inner surface of the vertical frame 24, closer to the room side X2 than the inner shoji screen 4 in the closed state.

[0020] As shown in Figures 1 to 3, the outer screen 3 is constructed by fitting a panel 35 made of three pieces of glass inside a frame body 30 made of an upper frame 31, a lower frame 32, a vertical frame 33 located on the door end side, and an outer meeting frame 34, which is a vertical frame located on the door tail side, assembled into a rectangular frame. The outer screen 3 is engaged with the exterior rails 211, 221 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction. The lower frame 32 of the outer screen 3 is provided with a door roller 36 that rolls on the exterior rail 221 of the lower frame 22.

[0021] The inner screen 4 is constructed by fitting a panel 45 made of three 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 end side, and an inner meeting frame 44 located on the door tail side. The inner screen 4 is engaged with the interior rails 212, 222 of the upper frame 21 and the lower frame 22 so as to be movable in the left-right direction. The lower frame 42 of the inner screen 4 is provided with a wheel 46 that rolls on the interior rail 222 of the lower frame 22.

[0022] As shown in Figures 2 and 3, the upper frame 31, lower frame 32, vertical frame 33 and outer meeting frame 34 of the outer screen 3 each have a composite structure in which resin frame materials 312, 322, 332, 342 are attached to the indoor side X2 of metal frame materials 311, 321, 331, 341. The upper frame 41, lower frame 42, vertical frame 43 and inner meeting frame 44 of the inner screen 4 each have a composite structure in which resin frame materials 412, 422, 432, 442 are attached to the indoor side X2 of metal frame materials 411, 421, 431, 441. This provides the outer screen 3 and inner screen 4 with excellent heat insulation and moisture resistance.

[0023] The wind stop member 6 will now be described. As shown in Figs. 4 to 7, the wind stop member 6 is disposed on the underside of the upper frame 21. The wind stop member 6 is disposed on the underside of the upper frame 21 above the joint 10 between the outer screen 3 and the inner screen 4. As shown in Figs. 6 and 7, the wind stop member 6 is disposed between the exterior rail 211 and the interior rail 212 that protrude downward from the upper frame 21, and is disposed over a predetermined range in the movement direction (left-right direction) of the outer screen 3 and the inner screen 4.

[0024] As shown in Figures 8 to 10, the wind stopper member 6 has an upper plate portion 61 fixed to the underside of the upper frame 21, and a plurality of fin portions 62 (plate-shaped materials) arranged hanging downward from the underside of the upper plate portion 61.

[0025] The multiple fin portions 62 are each formed from a thin plate-like member whose surface faces in the left-right direction (viewing direction) and are arranged side by side at intervals in the left-right direction (viewing direction). The multiple fin portions 62 are each formed from an elastic plate-like material. The multiple fin portions 62 elastically deform while contacting the upper ends of the outer screen 3 and the inner screen 4, and are arranged so that no gaps are created between the upper frame 21 and the outer screen 3, and between the upper frame 21 and the inner screen 4.

[0026] 6 and 7, the fin portion 62 has a thickness in the movement direction (left-right direction) of the outer screen 3 and the inner screen 4, and extends in the indoor-outdoor direction and the up-down direction. The fin portion 62 is formed from a rectangular plate material whose length in the indoor-outdoor direction is longer than its length in the up-down direction. Each of the multiple fin portions 62 extends in the indoor-outdoor direction between the outdoor rail 211 and the indoor rail 212 of the upper frame 21.

[0027] The lower ends of the multiple fin portions 62 extend to a position where they contact the upper end 314 of the inside side X2 of the open frame 313 that opens upward on the upper frame 31 of the outer screen 3, and the upper end 414 of the outside side X1 of the open frame 413 that opens upward on the upper frame 41 of the inner screen 4, as shown in Figure 6.

[0028] As a result, when the outer screen 3 and the inner screen 4 are in the closed position, as shown in Figure 6, in the portion of the multiple fin portions 62 where the outer screen 3 or inner screen 4 is located, the outside X1 portion abuts the inside X2 portion of the upper end of the outer meeting frame 34 of the outer screen 3, and the inside X2 portion abuts the outside X1 portion of the upper end of the inner meeting frame 44 of the inner screen 4.

[0029] As shown in Figs. 8 to 10, grooves 621, 622 (cuttable lines) are formed on one or the other surface of the multiple fin portions 62. The grooves 621, 622 are formed in the shape of lines extending in the vertical direction so that they can be cut. The grooves 621, 622 are formed by being recessed in the thickness direction from the surface of the fin portion 62, and extend in the vertical direction from the middle of the vertical direction to the lower end. The grooves 621, 622 are uncut when not in use, and are cut when the outer screen 3 or the inner screen 4 passes through. In this embodiment, the groove 621 is recessed in a triangular shape from the surface in a cross-sectional view as shown in Fig. 10.

[0030] Two one-surface grooves 621 are formed on one side of the left-right surface of the four fin portions 62a arranged on one side of the left-right direction (the left side in Figures 7 and 10, the front left side in Figure 8, and the rear left side in Figure 9) of the multiple fin portions 62, and no grooves are formed on the other side of the left-right surface.

[0031] The two one-side grooves 621 are spaced apart in the indoor / outdoor direction and extend from midway up and down to the lower end of the fin portion 62. Of the two one-side grooves 621, the groove 621a (first cuttable line) on the outside side X1 is formed in a position in the indoor / outdoor direction where it will be cut when the upper end of the outer screen 3 passes through the lower end of the fin portion 62. Of the two one-side grooves 621, the groove 621b (second cuttable line) on the inside side X2 is formed in a position in the indoor / outdoor direction where it will be cut when the upper end of the inner screen 4 passes through the lower end of the fin portion 62.

[0032] Two other-surface grooves 622 are formed on the other left-right surface of the four fin portions 62b arranged on the other left-right side of the multiple fin portions 62 (the right side in Figures 7 and 10, the rear right side in Figure 8, and the front right side in Figure 9), and no grooves are formed on the surface on one side in the left-right direction.

[0033] The two other-side grooves 622 are spaced apart in the indoor / outdoor direction and extend from midway up and down to the lower end of the fin portion 62. Of the two other-side grooves 622, the groove 622a (first groove) on the outside side X1 is formed in a position in the indoor / outdoor direction where it is cut off when the upper end of the outer screen 3 passes through the lower end of the fin portion 62. Of the two other-side grooves 622, the groove 622b (second groove) on the inside side X2 is formed in a position in the indoor / outdoor direction where it is cut off when the upper end of the inner screen 4 passes through the lower end of the fin portion 62.

[0034] In the windstop member 6 configured as above, when the outer screen 3 or the inner screen 4 passes through, the grooves 621, 622 are cut only at the portion where the outer screen 3 or the inner screen 4 passes through. Specifically, in the vertical direction of the fin portion 62, the grooves 621, 622 are cut upward by a predetermined length from the lower end only at the portion where the outer screen 3 or the inner screen 4 passes through. Also, in the horizontal direction in which the multiple fin portions 62 are arranged side by side, the grooves 621, 622 are cut only at the grooves 621, 622 formed in the fin portion 62 arranged in the range where the outer screen 3 and the inner screen 4 pass through in the horizontal direction. Therefore, the grooves 621, 622 are cut only at the portion where the outer screen 3 and the inner screen 4 pass through, and the other portions are not cut. Therefore, the windstop member 6 of this embodiment can improve the airtightness performance more than a conventional windstop member having multiple fin portions with cut slits.

[0035] Furthermore, even if there is a dimensional error or assembly error of the outer screen 3 and the inner screen 4, the grooves 621, 622 are cut only in the portion through which the outer screen 3 and the inner screen 4 pass, depending on the positional relationship due to the dimensional error or assembly error of the outer screen 3 and the inner screen 4. Also, since the height position of the screen (outer screen 3 and inner screen 4) varies depending on the degree of fitting adjustment of the screen (outer screen 3 and inner screen 4), the conventional wind stop member has a slit in the fin portion up to the upper limit of the height position of the screen (outer screen 3 and inner screen 4) or a position with a little more margin, and air leakage occurs from that portion. In contrast, the fin portion 62 of the wind stop member 6 of this embodiment does not cut the grooves 621, 622 except for the portion through which the screen (outer screen 3 or inner screen 4) passes, and no slit is made in the fin portion 62. Therefore, the windstop member 6 of this embodiment can improve the airtightness performance compared to a conventional windstop member having a plurality of fin portions with cut slits.

[0036] According to this embodiment, the following effects are achieved. The sliding window 1 of this embodiment includes a frame body 2 having an upper frame 21, an outer screen 3 and an inner screen 4 arranged so as to be movable in the left-right direction within the frame body 2, and a windstop member 6 arranged on the underside of the upper frame 21 above the joint 10 between the outer screen 3 and the inner screen 4 at a portion through which the outer screen 3 and the inner screen 4 pass. The windstop member 6 has a resin fin portion 62 that extends in the indoor / outdoor direction and in the vertical direction and is formed with a thickness in the direction in which the outer screen 3 and the inner screen 4 move. The fin portion 62 has grooves 621, 622 that extend in the vertical direction to the lower end and are uncut when not in use, and are cut when the outer screen 3 or the inner screen 4 passes through.

[0037] Therefore, the grooves 621, 622 are cut only at the places where the outer screen 3 and the inner screen 4 pass through, and other places are not cut. Therefore, the wind stopper member 6 of this embodiment can improve the airtightness performance compared to the conventional wind stopper member having multiple fin parts with cut slits.

[0038] In addition, in this embodiment, the grooves 621, 622 have grooves 621a, 622a that are cut when the upper end of the outer screen 3 passes over the lower end of the fin portion 62, and grooves 621b, 622b that are cut when the upper end of the inner screen 4 passes over the lower end of the fin portion 62.

[0039] Therefore, the grooves 621a, 622a, 621b, 622b are cut in the portions where the outer screen 3 and the inner screen 4 pass through. As a result, in the range where the outer screen 3 passes through, the grooves 621a, 622a are cut only in the range where the outer screen 3 passes through, and in the range where the inner screen 4 passes through, the grooves 621b, 622b are cut only in the range where the inner screen 4 passes through. Therefore, the grooves 621a, 622a, 621b, 622b are cut according to the individual ranges where the outer screen 3 and the inner screen 4 pass through, which further improves the airtightness performance.

[0040] Furthermore, in this embodiment, the recessed grooves 621, 622 are formed only on one surface of the fin portion 62. This makes it possible to easily manufacture the fin portion 62 having the recessed grooves 621, 622 formed therein.

[0041] 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.

[0042] In the above embodiment, the cuttable line is configured by a groove formed only on one side or only on the other side of the fin portion 62 (plate member), but is not limited thereto. For example, the cuttable line may be configured by a double-sided groove formed on both the one side and the other side of the fin portion 62 (plate member), or may be configured by a perforation.

[0043] In the above embodiment, the fin portion (plate-shaped portion) is provided with two grooves, and the grooves that are cut when the outer screen 3 or the inner screen 4 pass through are separate, but this is not limited to the above. For example, instead of the two grooves formed in the fin portion 62 (plate-shaped material) in the above embodiment, the fin portion (plate-shaped portion) may be provided with a single groove that combines the two grooves in the middle position between the two grooves in the above embodiment, and the single groove that is cut when the outer screen 3 and the inner screen 4 pass through may be provided with a single groove.
