Description

This disclosure relates to building materials.

Conventionally, sliding windows have been known in which the outer and inner screens, which are made by assembling an upper frame, a lower frame, a vertical frame, and a joint frame, are fitted together so that they can move left and right along rails (see, for example, Patent Document 1). The upper and lower frames of this sliding window are provided with airtight members that improve the airtightness of the joint frame by tightly abutting the joint frame of the inner screen when in the closed position.

JP 2017-180052 A

Generally, the upper and lower ends of the interlocking frames of the exterior sliding screens that make up a sliding window are configured to abut against the rail from the outside of the room, sealing the gap between the interlocking frame and the rail.

However, if the outer screen becomes loose, the force with which the upper and lower ends of the outer screen's interlocking frame abut against the rails will weaken, which could reduce airtightness.

The inventor therefore discovered the problem of providing a fixture that could reliably fit the outer screen door frame tightly against the rail, improving airtightness.

The fixture disclosed herein comprises a frame body formed by framing an upper frame, a lower frame, and a pair of left and right vertical frames, an outer screen and an inner screen that are housed inside the frame body and can move left and right along the exterior rail and interior rail provided on the upper and lower frames, and are respectively formed by assembling an upper frame, a lower frame, a vertical frame on the door end side, and a door fitting frame on the door tail side, and a pull-in member on at least one of the upper and lower frames that abuts against the outer screen fitting frame in the closed position, thereby pulling the outer screen fitting frame toward the interior side of the room.

This is a front view of a sliding window from the inside of the room. 2 is a longitudinal sectional view taken along line AA in FIG. 1. 2 is a cross-sectional view taken along line BB in FIG. 1. This is an oblique view of the outer frame of the exterior screen of a sliding window, viewed from above. This is an oblique view of the outer frame of the exterior sliding window screen from below.

Embodiments of the present disclosure will be described in detail below with reference to the drawings. Figures 1, 2, and 3 show a sliding window 1 as a fixture. The sliding window 1 is constructed by fitting two shoji screens, an outer shoji screen 3 located on the outside of the room and an inner shoji screen 4 located on the inside of the room, inside a frame body 2 formed into a rectangular shape by an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24, as well as one screen door 5 located on the outside of the outer shoji screen 3. X1 in the drawings indicates the outside side of the room, and X2 indicates the inside side of the room.

As shown in Figures 2 and 3, the outer screen 3 is constructed by fitting two pieces of glass 35 with a spacer 36 between them inside the frame body 30, which is made up 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 located on the door tail side, assembled into a rectangular shape. The inner screen 4 is constructed by fitting two pieces of glass 45 with a spacer 46 between them inside the frame body 40, which is made up 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, assembled into a rectangular shape. Both the outer screen 3 and the inner screen 4 have a vertically-hinged structure in which upper frames 31, 41 and lower frames 32, 42 are attached between the vertical frame 33 and the outer frame 34, and between the vertical frame 43 and the inner frame 44, respectively.

The outer screen 3 is engaged with the exterior rails 211, 221 provided on the upper frame 21 and the lower frame 22, respectively, so that it can move left and right. The inner screen 4 is engaged with the interior rails 212, 222 provided on the upper frame 21 and the lower frame 22, respectively, so that it can move left and right. The screen 5 is engaged with the screen rails 213, 223 provided on the outermost sides of the upper frame 21 and the lower frame 22, so that it can move left and right.

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, and 342 are attached to the indoor side of metal frame materials 311, 321, 331, and 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, and 442 are attached to the indoor side of metal frame materials 411, 421, 431, and 441. This gives the outer screen 3 and inner screen 4 excellent insulation and moisture resistance.

As shown in Figures 2 and 4, the upper end of the outer screen 3 has an engagement groove 3a that extends across the upper frame 31, vertical frame 33, and outer meeting frame 34 and engages with the exterior rail 211 of the upper frame 21. As shown in Figures 2, 5, and 6, the lower end of the outer screen 3 has an engagement groove 3b that extends across the lower frame 32, vertical frame 33, and outer meeting frame 34 and engages with the exterior rail 221 of the lower frame 22. Furthermore, as shown in Figure 2, the upper end of the inner screen 4 has an engagement groove 4a that extends across the upper frame 41, vertical frame 43, and inner meeting frame 44 and engages with the interior rail 212 of the upper frame 21. As shown in Figures 2 and 6, the lower end of the inner screen 4 has an engagement groove 4b that extends across the bottom frame 42, vertical frame 43, and inner meeting frame 44 and engages with the interior rail 222 of the lower frame 22. Inside the engagement grooves 3b, 4b of the outer screen 3 and inner screen 4, door rollers 37, 47 that move along the exterior rail 221 and interior rail 222 of the lower frame 22 are provided, respectively.

As shown in Figures 2 and 4, the upper frame 31 of the outer screen 3 is provided with a packing 313 made of a soft material such as rubber along the entire length of the inner edge of the engagement groove 3a on the exterior side. The packing 313 is provided at the upper end of the exterior side of the metal frame material 311 of the upper frame 31 so as to protrude toward the exterior surface 211a of the exterior rail 211.

Furthermore, a resin part 343 made of a hard resin material is provided on the upper end 34a of the outer meeting frame 34 of the outer screen 3 so as to fit along the inner surface of the engagement groove 3a. The resin part 343 is provided on the inner surface of the engagement groove 3a formed in the metal frame material 341 of the outer meeting frame 34 so as to sandwich the outdoor rail 211 from the indoor/outdoor direction between a pair of opening edges 343a, 343b. The distance between the pair of opening edges 343a, 343b is sufficiently smaller than the width of the engagement groove 3a provided in the upper frame 31.

As shown in Figures 2 and 5, the bottom frame 32 of the outer screen 3 is provided with a gasket 323 made of a soft material such as rubber along the entire length of the inner edge of the engagement groove 3b on the exterior side. The gasket 323 is provided at the lower end of the exterior side of the metal frame material 321 of the bottom frame 32 so as to protrude toward the exterior surface 221a of the exterior rail 221.

Furthermore, a resin part 344 made of a hard resin material is provided on the lower end 34b of the outer meeting frame 34 of the outer screen 3 so as to fit along the inner surface of the engagement groove 3b. The resin part 344 is provided on the inner surface of the engagement groove 3b formed in the metal frame material 341 of the outer meeting frame 34 so as to sandwich the outdoor rail 211 from the indoor/outdoor direction between a pair of opening edges 344a, 344b. The distance between the pair of opening edges 344a, 344b is sufficiently smaller than the width of the engagement groove 3b provided in the lower frame 32.

As shown in FIG. 1, a crescent lock 48 is provided at approximately the center in the vertical direction of the inner meeting frame 44 of the inner screen 4. The crescent lock 48 engages with a crescent receiver (not shown) provided on the outer meeting frame 34 of the outer screen 3, thereby bringing the outer meeting frame 34 of the outer screen 3 and the inner meeting frame 44 of the inner screen 4 into close contact with each other and locking them.

As shown in Figures 2, 3 and 6, an airtight member 6 is provided in the approximate center of the extension direction of the lower frame 22. The airtight member 6 is disposed on the upper surface 22a between the exterior rail 221 and the interior rail 222 in the approximate center of the extension direction of the lower frame 22. The approximate center of the extension direction of the lower frame 22 where the airtight member 6 is provided is a position that corresponds to approximately directly below the exterior joining frame 34 and the interior joining frame 44 that are positioned in the closed position and overlap in the indoor/outdoor direction.

The specific structure of the airtight member 6 will be further described with reference to Figures 7, 8, and 9. The airtight member 6 of this embodiment is composed of an airtight member body 61, multiple plate-like pieces 62, and an attraction member 7. The airtight member body 61, the plate-like pieces 62, and the attraction member 7 are integrally molded from a soft resin material.

The airtight member body 61 is formed in a block shape with a size that spans the outdoor rail 221 and the indoor rail 222 of the lower frame 22. As shown in FIG. 6, the airtight member body 61 is positioned lower than the outdoor rail 221. However, the upper surface 61a of the airtight member body 61 is positioned close to the outer screen 3 and the inner screen 4 so as not to interfere with the opening and closing operations of the outer screen 3 and the inner screen 4.

Two engaging protrusions 611, 611 are provided on the indoor end surface 61b of the airtight member body 61. The airtight member 6 is attached to the upper surface 22a of the lower frame 22 by inserting the engaging protrusions 611, 611 from the outdoor side into two engaging holes 222a, 222a provided in the indoor rail 222 of the lower frame 22.

The plate-shaped pieces 62 are provided on the indoor side of the upper surface 61a of the airtight member main body 61, protruding upward. More specifically, the plate-shaped pieces 62 are arranged in parallel with the indoor-outdoor direction near the indoor end of the upper surface 61a of the airtight member main body 61, and at a predetermined interval in the extension direction of the lower frame 22. As shown in FIG. 6, the plate-shaped pieces 62 have a height that overlaps with the lower end 44b of the inner fitting frame 44 of the inner screen 4. Therefore, the plate-shaped pieces 62 come into contact with the lower end 44b of the inner fitting frame 44 of the inner screen 4 that moves to open and close. At this time, the plate-shaped pieces 62 elastically deform and overlap so as to fall along the extension direction of the lower frame 22. As a result, the plate-shaped pieces 62 block the portion of the engagement groove 4b of the inner fitting frame 44 that is arranged in the closed position that is more outdoor than the indoor rail 222, ensuring airtightness.

The attraction member 7 is provided at the outer end of the upper surface 61a of the airtight member body 61, protruding upward. More specifically, as shown in Figures 6 and 7, the attraction member 7 is made of a small block piece that extends upward from the upper surface 61a of the airtight member body 61 along the indoor side surface 221b of the outdoor rail 221. The attraction member 7 is in close contact with the indoor side surface 221b of the outdoor rail 221. The upper end surface 71 of the attraction member 7 is positioned lower than the upper end of the outdoor rail 221. Therefore, there is no hindrance when the wheel 37 of the outer sash 3 rolls along the outdoor rail 221.

As shown in Figures 7, 8 and 9, the pulling member 7 has an indoor end face 72 that protrudes most from the indoor side face 221b of the outdoor rail 221 toward the indoor side. This indoor end face 72 is arranged approximately parallel to the indoor side face 221b of the outdoor rail 221. On both the left and right sides of this indoor end face 72, inclined faces 73, 73 are provided that incline from the indoor end face 72 toward the indoor side face 221b of the outdoor rail 221.

The amount of protrusion of the pull member 7 from the indoor side surface 221b of the outdoor rail 221 toward the indoor side, i.e., the distance from the indoor side surface 221b of the outdoor rail 221 to the indoor end surface 72 of the pull member 7, is smaller than the size of the gap between the indoor opening edge 3b1 (see Figure 5) of the engagement groove 3b of the lower frame 32 of the outer screen 3 and the indoor side surface 221b of the outdoor rail 221. However, this distance is slightly larger than the size of the gap between the indoor opening edge 344b (see Figure 5) of the plastic part 344 that clamps the outdoor rail 221 at the lower end 34b of the outer meeting frame 34 of the outer screen 3 and the indoor side surface 221b of the outdoor rail 221.

Next, the action and effect of the pulling member 7 will be explained. When the outer door frame 34 of the outer door frame 34 moves from the open position to the closed position, the opening edge 344b on the indoor side of the resin part 344 at the lower end 34b of the outer door frame 34 first comes into contact with the inclined surface 73. The distance from the indoor side surface 221b of the outdoor rail 221 to the indoor end surface 72 of the pulling member 7 is smaller than the size of the gap between the indoor opening edge 3b1 (see Figure 5) of the engagement groove 3b of the lower frame 32 of the outer door frame 3 and the indoor side surface 221b of the outdoor rail 221. Therefore, when the outer door frame 3 moves, the engagement groove 3b of the lower frame 32 does not interfere with the pulling member 7, and the opening and closing operation of the outer door frame 3 does not become heavy.

When the exterior meeting frame 34 moves further toward the closed position, the opening edge 344b on the indoor side of the resin part 344 is gradually guided toward the indoor side along the inclined surface 73. As a result, the exterior meeting frame 34 is gradually drawn toward the indoor side as shown by the white arrow in FIG. 6. When the exterior screen 3 stops at the closed position, the opening edge 344b on the indoor side of the resin part 344 is disposed on the indoor end surface 72 of the drawing member 7 and is drawn most toward the indoor side. Therefore, the opening edge 344a on the outdoor side of the resin part 344 is reliably in close contact from the outdoor side toward the outdoor side surface 221a of the outdoor rail 221. Therefore, in addition to improving airtightness by drawing the exterior meeting frame 34 to the interior meeting frame 44 by locking the crescent lock 48, the airtightness can also be improved at the lower end 34b of the exterior meeting frame 34 of the exterior screen 3.

The pulling member 7 is arranged to protrude from the indoor side surface 221b of the outdoor rail 221 of the lower frame 22 toward the indoor side, and has an inclined surface 73 that gradually guides the outdoor meeting frame 34 of the outdoor screen 3 toward the indoor side by abutting against the outdoor meeting frame 34 of the outdoor screen 3 that moves toward the closed position. Therefore, the lower end portion 34b of the outdoor meeting frame 34 of the outdoor screen 3 is smoothly guided toward the indoor end surface 72 of the pulling member 7.

Since the pulling member 7 is integral with the airtight member 6, simply by attaching the airtight member 6 to the lower frame 22, in addition to the effect of improving the airtightness of the lower end 44b of the inner joint frame 44 by the airtight member 6, the pulling member 7 can easily improve the airtightness of the lower end 34b of the outer joint frame 34.

The pulling member 7 shown in the above embodiment is molded integrally with the airtight member body 61 of the airtight member 6. However, as shown in FIG. 10, the pulling member 7 may be formed separately from the airtight member 6 and attached to the indoor side surface 221b of the outdoor rail 221 of the bottom frame 22 by an appropriate fixing means such as double-sided adhesive tape or engagement between an engagement hole and an engagement protrusion. This allows the pulling member 7 to be retrofitted to an existing bottom frame 22 to which the airtight member 6 is attached.

Figures 11 and 12 show the attraction member 8 according to the second embodiment. The parts with the same reference numerals as those of the airtight member 6 having the attraction member 7 according to the first embodiment shown in Figures 7 and 8 show parts with the same configuration. The detailed description of these parts is omitted below, as they are referred to in the above description.

The pull-in member 8 is made of a plurality of plate-shaped members 81 that protrude upward from the outer end of the upper surface 61a of the airtight member body 61. The plate-shaped members 81 are each molded integrally with the upper surface 61a of the airtight member body 61 using soft resin. Each plate-shaped member 81 extends vertically from the upper surface 61a of the airtight member body 61 along the indoor side surface 221b of the outdoor rail 221, and is arranged side by side at intervals along the extension direction of the outdoor rail 221. The plate-shaped members 81 are each in close contact with the indoor side surface 221b of the outdoor rail 221. Since the plate-shaped members 81 are each positioned lower than the upper end of the outdoor rail 221, there is no hindrance when the wheel 37 of the outer sash 3 rolls along the outdoor rail 221.

Each plate-like member 81 has the same protruding height from the indoor side surface 221b of the outdoor rail 221 toward the indoor side. Since the plate-like member 81 can easily bend when it comes into contact with the frame body 30 of the outer screen 3, the protruding height of each plate-like member 81 toward the indoor side may be equal to or greater than the size of the gap between the indoor side opening edge 3b1 (see Figure 5) of the engagement groove 3b of the lower frame 32 of the outer screen 3 and the indoor side surface 221b of the outdoor rail 221. As a result, even if the pulling member 8 made of the plate-like member 81 comes into contact with the outer meeting frame 34 of the outer screen 3, it can pull the outer meeting frame 34 toward the indoor side, just like the pulling member 7.

The protruding height of each of the plate-like members 81 toward the indoor side may be different as shown in FIG. 13. In detail, the protruding height of each of the plate-like members 81 toward the indoor side from the indoor side surface 221b of the outdoor rail 221 gradually increases from the plate-like members 81a, 81a arranged at both ends of the arrangement direction of the plate-like members 81 toward the plate-like members 81b, 81b arranged on the center C side of the extension direction of the outdoor rail 221. In this way, the drawing member 8 can gradually increase the force with which it draws the outdoor meeting frame 34 toward the indoor side as the outdoor screen 3 approaches the closed position, so that the outdoor meeting frame 34 can be drawn more reliably toward the indoor side.

The attraction member 8 shown in Figures 11, 12, and 13 is composed of six plate-shaped members 81. However, it is sufficient that the attraction member 8 has at least one plate-shaped member 81. The attraction member 8 may be formed separately from the airtight member 6, similar to the attraction member 7 shown in Figure 10, and attached to the indoor side surface 221b of the outdoor rail 221.

The airtight member 6 having the attracting members 7, 8 and the attracting members 7, 8 described above may be provided on the upper frame 21. When the airtight member 6 having the attracting members 7, 8 and the attracting members 7, 8 are provided on the upper frame 21 and the lower frame 22, respectively, the airtightness of both the upper end 34a and the lower end 34b of the outer meeting frame 34 of the outer screen 3 can be improved. In this case, even if the sliding window 1 has a large height dimension that has a height from the floor to the ceiling, the airtightness of the overlapping portion of the outer meeting frame 34 and the inner meeting frame 44 can be improved.
