When dew condensation or water droplets (hereinafter, also referred to as "water droplets") adhere to the window frame, the water droplets or the like tend to hang down along the outer surface of the vertical frame of the window frame. These water droplets reach the window sill that supports the window frame, and if they hang down from the edge of the window sill along the outer wall, they cause stains due to water stains.

An object of the present invention is to provide a window structure capable of suppressing the dripping of water droplets or the like from the edge of a window sill along a wall and suppressing the generation of stains due to water stains.

One aspect of the present invention is a window structure including a window frame arranged between a pair of pillars and a window sill that supports the window frame. The window sill in this window structure has a support plate that supports the window frame and an upper surface groove portion that is provided on the upper surface of the support plate and extends in the depth direction of the window, and the window sill is supported by the window sill. , The upper surface groove portion is arranged on at least one of the downward extension of the outer surface of the vertical frame of the window frame and the downward extension of the inner surface of the pillar.

According to such a configuration, when water droplets or the like drips along the outer surface of the vertical frame of the window frame or the inner side surface of the pillar such as a pipe pillar, the water droplets or the like enter the groove on the upper surface of the lower window sill and the upper surface thereof. It flows along the groove toward the destination (outdoor). As a result, it is possible to prevent water droplets and the like from being transmitted from the side of the window sill to the wall and dripping.

In the window structure, a plurality of upper surface grooves may be provided in parallel with each other on the upper surface of the support plate. When a plurality of upper surface grooves are provided corresponding to the left and right sides of the window frame, water droplets and the like dripping on the left and right sides of the window frame can be captured by the upper surface grooves. Further, when a plurality of upper surface grooves are provided on one of the left and right sides of the window frame, the plurality of upper surface grooves can more reliably capture water droplets and the like.

In the window structure, the upper surface of the support plate may be provided with a communication groove portion for communicating a plurality of upper surface groove portions with each other. As a result, since the plurality of upper surface grooves are communicated with each other by the communication grooves, water droplets and the like captured in each upper surface groove can be flowed while being dispersed in the plurality of upper surface grooves by the communication grooves.

In the window structure, a lower surface groove portion extending in the width direction of the window may be provided on the protruding portion on the lower surface of the support plate. As a result, water droplets or the like flowing along the lower surface of the support plate are captured in the lower surface groove portion, so that it is possible to prevent the water droplets or the like from wrapping around the lower surface of the window sill and being transmitted to the wall.

In the window structure, each of the upper surface and the lower surface of the support plate may be provided so as to be inclined so as to be lowered from the indoor side to the outdoor side. As a result, the water droplets captured in the groove on the upper surface of the support plate and the water droplets adhering to the upper and lower surfaces of the support plate can be positively flowed to the outside.

According to the present invention, it is possible to provide a window structure capable of suppressing the dripping of water droplets or the like from the edge of the window sill along the wall and suppressing the generation of stains due to water stains.

The upper surface groove portion 210 is arranged in at least one of them. In the present embodiment, the upper surface groove portion 210 is arranged on the lower extension of both the outer surface 11s of the vertical frame 11 and the inner surface 2s of the pillar 2. In other words, the outer surface 11s of the vertical frame 11 of the window frame 10 is located on the upper surface groove 210, and the inner surface 2s of the pillar 2 is located on the upper surface groove 210.

When a plurality of upper surface groove portions 210 are provided, the outer surface 11s of the vertical frame 11 and the inner side surface 2s of the pillar 2 may be located on the same (one) upper surface groove portions 210, or they are different. The outer surface 11s of the vertical frame 11 and the inner side surface 2s of the pillar 2 may be located on each of the upper surface groove portions 210. Further, the outer surface 11s of the left and right vertical frames 11 and the inner side surfaces 2s of the left and right pillars 2 may be arranged on the upper surface groove portion 210.

As described above, since the outer side surface 11s of the vertical frame 11 and the inner side surface 2s of the pillar 2 are located on the upper surface groove portion 210, water droplets are formed along the vertical frame 11 of the window frame 10 and the inner side surface 2s of the pillar 2. When the water droplets or the like hang down, the water droplets or the like enter the upper surface groove portion 210 of the lower window sill 20, pass through the upper surface groove portion 210, and flow toward the destination portion 201 (outdoor). As a result, it is possible to prevent water droplets and the like from being transmitted from the side of the window sill 20 to the wall.

FIG. 2A shows a perspective view seen from the upper surface 21a side, and FIG. 2B shows a perspective view seen from the lower surface 21b side.
As shown in FIG. 2A, the upper surface 21a of the support plate 21 of the window sill 20 applied in the present embodiment is provided with three upper surface groove portions 210 on each of the left and right sides. Further, these upper surface groove portions 210 are communicated with each other by the communication groove portion 220. Water droplets or the like dripping along the vertical frame 11 of the window frame 10 enter the upper surface groove portion 210 and are discharged to the outside from the destination portion 201. Further, water droplets or the like that have entered the communication groove portion 220 along the window frame 10 also enter the communication groove portion 220 while being dispersed from the communication groove portion 220 into any of the upper surface groove portions 210, and are discharged to the outside from the destination portion 201.

Further, the destination portion 201 protrudes outdoors, and even if rainwater or the like is splashed on the destination portion 201, the rainwater or the like is captured by the upper surface groove portion 210 and flows in the direction of the destination portion 201. As a result, even if rainwater or the like is applied, it is possible to suppress the flow to the side (armpit portion) of the window sill 20, and it is possible to suppress the dripping from the side (armpit portion) of the window sill 20 along the wall.

Further, as shown in FIG. 2B, the lower surface 21b of the support plate 21 may be provided with a lower surface groove portion 230 extending in the width direction of the window. The lower surface groove portion 230 is a groove provided linearly in the width direction of the support plate 21. The lower surface groove portion 230 is provided in the destination portion 201. As a result, water droplets or the like flowing along the lower surface 21b of the support plate 21 are captured by the lower surface groove portion 230. For example, even when water droplets or the like discharged from the outdoor side of the upper surface groove portion 210 wrap around the lower surface 21b of the support plate 21, they are captured by the lower surface groove portion 230 and do not reach the wall side. As a result, it is possible to prevent water droplets and the like from wrapping around the lower surface 21b and being transmitted to the wall.

3A and 3B are schematic views illustrating the window structure according to the present embodiment.
FIG. 3A shows a front view, and FIG. 3B shows a sectional view taken along line AA of FIG. 3A.
As shown in FIG. 3A, in the window structure 1 according to the present embodiment, the upper surface groove portion 210 is arranged on the downward extension of the outer surface 11s of the vertical frame 11 of the window frame 10. Further, the upper surface groove portion 210 is also arranged on the downward extension of the inner side surface 2s of the pillar 2.

When a plurality of upper surface groove portions 210 are provided, the relative positions of the window sill 20 and the window frame 10 are slightly displaced during construction, or the relative positional relationship needs to be adjusted. However, the outer surface 11s and the inner surface 2s can be arranged on any of the upper surface groove portions 210. Further, by providing the plurality of upper surface groove portions 210, the upper surface groove portions 210 are arranged on the downward extension of the front surface 11f of the vertical frame 11 and on the downward extension of the front surface 2f of the pillar 2. As a result, even if there are water droplets dripping along the front surface 11f of the vertical frame 11 or the front surface 2f of the pillar 2, they can be received by the upper surface groove portion 210 and discharged to the outside.

FIG. 4 is a partial perspective view illustrating the positional relationship between the window frame and the pillar and the upper surface groove portion.
FIG. 5 is a partial plan view illustrating the positional relationship between the window frame and the pillar and the upper surface groove portion.
FIG. 6 is a schematic cross-sectional view of the window sill portion. FIG. 6 shows a cross-sectional view taken along the line BB of FIG.
In the example of the window structure 1 shown in FIGS. 4 to 6, three upper surface groove portions 210 are provided on one side on the left and right sides, and the outer surface 11s of the vertical frame 11 of the window frame 10 is provided on the upper surface groove portion 210 in the center. And the inner side surface 2s of the pillar 2 is located.

Further, the communication groove 220 is located below the horizontal frame 12 on the lower side of the window frame 10. As shown in FIG. 6, it is desirable that each of the upper surface 21a and the lower surface 21b of the support plate 21 of the window sill 20 is inclined so as to be lowered from the indoor side to the outdoor side. In the present embodiment, the upper surface 21a and the lower surface 21b are each provided with an inclination of an angle θ. Due to this inclination, water droplets and the like captured by the upper surface groove portion 210 of the support plate 21 and water droplets and the like adhering to the upper and lower surfaces (other than the upper surface groove portion 210) of the support plate 21 can be positively flowed to the outside. Further, water droplets and the like adhering to the lower surface 21b will actively flow to the destination portion 201 and will be captured by the lower surface groove portion 230.

Here, when the entire upper surface 21a of the support plate 21 is provided with an inclination of an angle θ, a gap is likely to occur between the lower surface of the window frame 10 and the upper surface 21a of the support plate 21. A sealing material (not shown) is embedded here, but there is a possibility that water droplets or the like will seep through the gaps. However, since the communication groove 220 is arranged below the window frame 10 as in the present embodiment, even if water droplets or the like permeate through the gap, they are captured by the communication groove 220 and effectively enter the room side. It can be suppressed. Water droplets or the like captured in the communication groove 220 are transmitted to the upper surface groove 210, positively flow to the destination portion 201 due to the inclination, and are discharged from the destination portion 201 to the outside.

As described above, according to the window structure 1 according to the embodiment, it is possible to suppress water droplets and the like from dripping from the edge of the window sill 20 along the wall, and to suppress the generation of stains due to water stains.
