JP7526652B2 - Partition window - Google Patents

Description

This disclosure relates to partition windows.

Conventionally, partition windows are sometimes installed in indoor spaces as a retrofit to separate the interior space. A partition window is comprised of 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.

Incidentally, although it is not a window like a partition window, a technology has been disclosed for retrofitting a partition panel that divides an indoor space (see, for example, Patent Document 1). In Patent Document 1, an existing baseboard is placed at the boundary between the floor and wall of the room. Therefore, in the technology described in Patent Document 1, when a partition panel is to be installed in an indoor space, a baseboard escape section is formed in the pillar that is placed along the wall of the partition panel to allow the existing baseboard to escape.

JP 2006-183273 A

When retrofitting a partition window in a room where a baseboard exists at the boundary between the floor and the wall, providing a clearance for the baseboard in the vertical frame of the partition window will result in a complex shape of the vertical frame, which will be costly to process. Also, when retrofitting a partition window, it is possible to construct the upper side of the baseboard on-site using wood or other materials so that there is no gap between the wall and the pillar. However, this makes the construction work complicated.

The purpose of this disclosure is to provide a partition window that is easy to install.

The present disclosure relates to a partition window that divides a space within a room where a baseboard is provided at the boundary between the floor and the wall, and that comprises a frame body having a vertical frame that is arranged along the surface of the baseboard facing the room, a paper screen that is arranged within the frame body, and a vertical frame attachment spacer member that is arranged between the vertical frame and the wall at the top of the baseboard and extends in the up-down direction.

FIG. 2 is a diagram showing a partition window according to an embodiment. 2 is a cross-sectional view taken along line AA in FIG. 1. 2 is a cross-sectional view taken along line BB in FIG. 1. FIG. 4 is an enlarged view of a portion of FIG. 3 where a vertical frame mounting spacer member is arranged. FIG. 4 is an oblique view of a spacer member for mounting a vertical frame.

One embodiment of the present disclosure will be described in detail below with reference to the drawings. In this specification, the term "visible 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.

As shown in FIG. 1, the partition window 1 of the present disclosure is installed as a retrofit in an existing room 10. In the existing room 10, a baseboard 15 is provided at the boundary between the floor surface 11 and the wall surfaces 12, 13. The baseboard 15 is formed at the corner of the boundary between the floor surface 11 and the wall surfaces 12, 13, has a predetermined width and a predetermined height, and extends in the depth direction.

As shown in FIG. 1, the partition window 1 is placed midway in the depth direction of the baseboard 15 of the room 10, dividing the space inside the room 10. The partition window 1 divides the existing room 10 into a back room 101 and a front room 102. The partition window 1 is formed in the shape of a wall that is fixed to the floor 11, left and right walls 12, 13, and ceiling 14 of the room 10 midway in the depth direction of the room 10.

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. The partition window 1 is, for example, a window designed as an inner window constituting the interior window of a double-glazed window, installed midway in the depth direction of an existing room 10, and divides the room into a back room 101 and a front room 102. Note that the partition window 1 may also be constructed using a window designed as a partition window from the beginning, rather than being constructed using a window designed as an inner window of a double-glazed window.

The partition window 1 is a so-called sliding window, and as shown in Figures 1 to 3, it 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 that they can 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. In this embodiment, the first shoji screen 3 (shoji screen) and the second shoji screen 4 (shoji screen) each have a resin frame body that is framed in a rectangular shape by an upper frame, a lower frame, and left and right vertical frames, and glass (surface material) arranged within the frame body.

The frame body 2 is formed into a rectangular shape by an elongated upper frame 21, a lower frame 22, and left and right vertical frames 23, 24. The frame body 2 is made of, for example, resin or metal.

The vertical frames 23, 24 are disposed at the left and right ends of the frame body 2, respectively, and extend in the vertical direction. The vertical frames 23, 24 are disposed along the vertical surface 151 (surface) on the indoor side of the baseboard 15.

As shown in FIG. 4, the vertical frames 23, 24 each have a vertical frame prospective direction extension plate 251 extending a predetermined length in the prospective direction, a front inner protruding plate 252 protruding inward in the prospective direction of the frame body 2 from the front end of the vertical frame prospective direction extension plate 251, a rear inner protruding plate 253 protruding inward in the prospective direction of the frame body 2 from the rear end of the vertical frame prospective direction extension plate 251, an intermediate inner protruding plate 254 protruding inward in the prospective direction of the frame body 2 from midway in the prospective direction (depth direction) of the vertical frame prospective direction extension plate 251, and a plurality of outer protrusions 255 protruding outward in the prospective direction of the frame body 2 from the outer surface in the prospective direction of the vertical frame prospective direction extension plate 251. The vertical frame projection direction extension plate 251, the front inner protruding plate 252, the rear inner protruding plate 253, the middle inner protruding plate 254, and the multiple outer protrusions 255 are formed over the entire longitudinal area of the vertical frames 23, 24.

The multiple outer protrusions 255 protrude from the outer surface of the vertical frame prospective direction extending plate 251 to the outside of the frame body 2 by the same protrusion amount. When the vertical frame mounting spacer member 5 (described later) is placed between the vertical frames 23, 24 and the wall surfaces 12, 13 at the top of the baseboard 15, the multiple outer protrusions 255 abut against the indoor side surface 511 of the prospective direction extending vertical plate 51 of the vertical frame mounting spacer member 5. As a result, by arranging the multiple outer protrusions 255 between the vertical frame prospective direction extending plate 251 of the vertical frames 23, 24 and the prospective direction extending vertical plate 51 of the vertical frame mounting spacer member 5, a gap is formed in the portion where the multiple outer protrusions 255 are not arranged. The multiple outer protrusions 255 are provided, for example, to improve the strength of the screw fastening.

As shown in FIG. 1, a vertical frame mounting spacer member 5 is disposed between the vertical frames 23, 24 and the wall surfaces 12, 13 above the baseboard 15.

As shown in Figs. 1 and 5, the vertical frame mounting spacer member 5 is formed in an elongated shape extending vertically along the wall surfaces 12, 13. As shown in Fig. 1, the vertical frame mounting spacer member 5 is disposed between the vertical frames 23, 24 and the wall surfaces 12, 13 at the top of the baseboard 15. For example, the vertical frame mounting spacer member 5 may be made of a metal such as aluminum material, or may be made of resin. The vertical frame mounting spacer member 5 is fixed to the wall surfaces 12, 13, for example, with screws.

As shown in Figs. 4 and 5, the vertical frame mounting spacer member 5 has a vertical plate 51 extending in the projection direction, a plurality of wall side upright plates 52 rising from the outer surface of the vertical plate 51 extending in the projection direction toward the wall surfaces 12 and 13, and a first vertical frame side protruding rib 53 and a second vertical frame side protruding rib 54 protruding from the interior side surface 511 of the vertical plate 51 extending in the projection direction toward the vertical frames 23 and 24. The first vertical frame side protruding rib 53 and the second vertical frame side protruding rib 54 are positioned at positions spaced apart in the projection direction. In this embodiment, the first vertical frame side protruding rib 53 is positioned at the back side in the projection direction (depth direction). The second vertical frame side protruding rib 54 is positioned at the front side in the projection direction (depth direction).

The projection-direction-extending vertical plate 51 is formed as a long plate extending along the wall surfaces 12, 13 at a position a predetermined distance away from the wall surfaces 12, 13. The projection-direction-extending vertical plate 51 has a thickness in the left-right direction of the projection direction, extends a predetermined length in the projection direction, and is formed as a plate extending in the up-down direction.

All of the multiple wall-side standing plates 52 are formed with the same length to the wall surfaces 12, 13. Each of the multiple wall-side standing plates 52 has a bent piece 521 at the tip that bends in one of the prospective directions along the wall surfaces 12, 13. Each of the multiple bent pieces 521 abuts against the wall surfaces 12, 13.

The first vertical frame side protruding rib 53 is positioned adjacent to the rear side of the rearmost outer protrusion 255a of the multiple outer protrusions 255 that protrude from the outer surface of the vertical frame prospective direction extending plate 251 of the vertical frames 23, 24 to the outside of the frame body 2. The second vertical frame side protruding rib 54 is positioned adjacent to the front side of the frontmost outer protrusion 255b of the multiple outer protrusions 255 that protrude from the outer surface of the vertical frame prospective direction extending plate 251 of the vertical frames 23, 24 to the outside of the frame body 2.

When the vertical frame mounting spacer member 5 is disposed between the vertical frames 23, 24 and the wall surfaces 12, 13, the first vertical frame side protruding rib 53 restricts the movement of the outer protrusion 255a toward the rear side, and the second vertical frame side protruding rib 54 restricts the movement of the outer protrusion 255b toward the front side, thereby restricting the movement of the vertical frames 23, 24 in the projection direction (depth direction). This positions the vertical frames 23, 24 in the projection direction. The first vertical frame side protruding rib 53 and the second vertical frame side protruding rib 54 constitute a positioning portion that restricts the movement of the vertical frames 23, 24 in the projection direction and positions the vertical frames 23, 24 in the projection direction.

The distance from the wall surfaces 12, 13 to the indoor surface 511 of the vertical plate 51 extending in the projection direction of the vertical frame mounting spacer member 5 is the same as the distance from the wall surfaces 12, 13 to the indoor vertical surface 151 of the baseboard 15. Therefore, by placing the vertical frame mounting spacer member 5 on the top of the baseboard 15, the indoor vertical surface 151 of the baseboard 15 and the indoor surface 511 of the vertical plate 51 extending in the projection direction of the vertical frame mounting spacer member 5 are located on the same plane. This allows the vertical frames 23, 24 to be placed along the indoor vertical surface 151 of the baseboard 15 and the indoor surface 511 of the vertical plate 51 extending in the projection direction of the vertical frame mounting spacer member 5. Therefore, since the vertical frames 23, 24 can be placed across the baseboard 15 and the vertical frame mounting spacer member 5, the vertical frames 23, 24 can be easily attached to the wall surfaces 12, 13.

As shown in FIG. 5, the vertical frame mounting spacer member 5 has a length adjustment cut portion 55 that can be cut to adjust the vertical length. In this embodiment, the length adjustment cut portion 55 is provided at the upper end of the vertical frame mounting spacer member 5.

The length adjustment cutting section 55 has, for example, a plurality of cutting lines 551. The plurality of cutting lines 551 are formed on the surface of the vertical frame mounting spacer member 5, extending in a direction perpendicular to the direction in which the vertical frame mounting spacer member 5 extends, and are arranged at predetermined intervals from the end of the vertical frame mounting spacer member 5. The cutting lines 551 are formed, for example, such that the cross-sectional shape is recessed into a triangular shape from the surface of the vertical frame mounting spacer member 5. Note that the shape of the cutting lines 551 is not limited to this cross-sectional shape.

The length adjustment cutting section 55 can adjust the length of the vertical frame mounting spacer member 5 by cutting the vertical frame mounting spacer member 5 at the cutting lines 551 according to the height of the baseboard 15 and the ceiling 14. This allows the length of the vertical frame mounting spacer member 5 to be adjusted according to the height of the baseboard 15 and the ceiling 14. For example, the spacing between adjacent cutting lines 551 can be set to 1.0 cm or 0.5 cm. The number of cutting lines 551 and the spacing between adjacent cutting lines 551 are not limited to this embodiment. The spacing between multiple cutting lines 551 does not have to be equal.

Next, the procedure for installing the partition window 1 of the present disclosure in an existing room 10 will be described. The partition window 1 is a retrofit partition window, and is constructed by first attaching the frame body 2 halfway in the depth direction of the existing room 10, and then fitting the first shoji screen 3 and the second shoji screen 4 inside the frame body 2.

Here, we will mainly explain the procedure for attaching the vertical frames 23, 24 of the frame body 2 to the walls 12, 13. In the existing room 10, baseboards 15 are provided at the boundaries between the floor surface 11 and the walls 12, 13.

First, the longitudinal length of the vertical frame mounting spacer member 5 is adjusted to match the length from the top surface 152 of the baseboard 15 to the ceiling 14 by cutting one of the multiple cutting lines 551 of the length adjustment cutting section 55.

Next, the vertical frame mounting spacer member 5 is placed on top of the upper surface 152 of the baseboard 15, so that the vertical frame mounting spacer member 5 is positioned along the wall surfaces 12 and 13. The vertical frame mounting spacer member 5 is then fixed with screws while positioned along the wall surfaces 12 and 13. As a result, the indoor vertical surface 151 of the baseboard 15 and the indoor surface 511 of the forward-direction extending vertical plate 51 of the vertical frame mounting spacer member 5 are positioned on the same plane.

Next, the vertical frames 23, 24 are arranged so as to straddle the indoor vertical surface 151 of the baseboard 15 and the indoor surface 511 of the vertical plate 51 extending in the forward direction of the vertical frame mounting spacer member 5. In addition, in the forward direction (depth direction) of the vertical frames 23, 24, the first vertical frame side protruding rib 53 is positioned at the rear side of the innermost outer protrusion 255a, and the second vertical frame side protruding rib 54 is positioned at the front side of the outer protrusion 255b on the front side, and the vertical frames 23, 24 are arranged so as to straddle the baseboard 15 and the vertical frame mounting spacer member 5. In this state, the vertical frames 23, 24 are fixed to the vertical frame mounting spacer member 5 with screws. The method of fixing the vertical frame mounting spacer member 5 and the vertical frames 23, 24 is not limited, and for example, the vertical frame mounting spacer member 5 and the vertical frames 23, 24 may be fixed to the wall surface 12, 13 by screwing them together.

After the vertical frames 23, 24 are attached, the upper frame 21 is fixed to the ceiling 14, and the lower frame 22 is fixed to the floor surface 11. The first shoji screen 3 and the second shoji screen 4 are then fitted inside the frame body 2. In this way, the partition window 1 can be set in the existing room 10.

The present embodiment provides the following effects. The partition window 1 of the present embodiment is a partition window that divides a space in a room where a baseboard 15 is provided at the boundary between the floor surface 11 and the wall surfaces 12, 13, and includes a frame body 2 having vertical frames 23, 24 arranged along the vertical surface 151 on the indoor side of the baseboard 15, a first shoji screen 3 and a second shoji screen 4 arranged within the frame body 2, and a vertical frame mounting spacer member 5 that is arranged between the vertical frames 23, 24 at the top of the baseboard 15 and the wall surfaces 12, 13 and extends in the up-down direction. As a result, by arranging the vertical frame mounting spacer member 5 at the top of the baseboard 15, the vertical frames 23, 24 can be easily attached to the wall surfaces 12, 13. Therefore, the construction work of attaching the vertical frames 23, 24 to the wall surfaces 12, 13 can be easily performed.

In this embodiment, the vertical frame mounting spacer member 5 is made of metal. As a result, when the vertical frame mounting spacer member 5 is placed between the vertical frames 23, 24 and the wall surfaces 12, 13, the vertical frame mounting spacer member 5 is less likely to deform. Because the vertical frame mounting spacer member 5 is made of metal, it is less likely to deteriorate over time.

In this embodiment, the vertical frame mounting spacer member 5 has a length adjustment cut section 55 that can be cut to adjust the vertical length. This makes it easy to adjust the length of the vertical frame mounting spacer member 5 according to the height of the baseboard 15 and ceiling 14.

In this embodiment, the vertical frame mounting spacer member 5 includes a first vertical frame side protruding rib 53 and a second vertical frame side protruding rib 54 that restrict the movement of the vertical frames 23, 24 in the projection direction and position the vertical frames 23, 24 in the projection direction. As a result, the vertical frame mounting spacer member 5 can position the vertical frames 23, 24 in the projection direction, facilitating the construction work of mounting the vertical frames 23, 24 to the wall surfaces 12, 13.

Note that this disclosure is not limited to the above-described embodiments, and any modifications, improvements, etc. that achieve the objectives of this disclosure are included in this disclosure.

In the above embodiment, the positioning portion is configured by two ribs, the first vertical frame side protruding rib 53 and the second vertical frame side protruding rib 54, but is not limited to this. The positioning portion may be configured by either the first vertical frame side protruding rib 53 or the second vertical frame side protruding rib 54, or may be configured by three or more ribs.
