Description

[Detailed Description of the Invention] Industrial Field of Application This invention relates to a watertight structure of a horizontal rotating window, especially the lower corner portion thereof.

Prior Art In a horizontal rotating window, a tight material is usually attached to the outer circumferential side of a stile in a rotating shoji, and a contact portion with which the tight material comes into contact is provided on the inner circumferential surface of the sash frame.

In the corner part of such a horizontal rotating window, there is a tight material corner where the tight material of the vertical and horizontal frames of the rotating shoji is continuous at the corner of the sash frame where the tight material contact parts of the vertical and horizontal frames of the sash frame are continuous. However, if the shoji is installed incorrectly and tilted, gaps are likely to form in this area, and rainwater can easily enter through such gaps, especially at the lower corners, causing horizontal axis rotation. The watertight performance of the window is reduced.

In order to close the gap that occurs when the outer edge of the tight material forms an arc at the corner of a conventional revolving window, a corner block with a surface that corresponds to the arc of the tight material is attached to the sash frame.
-24874 Publication, Japanese Utility Model Publication No. 55-22483), and those in which a protrusion is formed on the corner of the sash frame to which the tight material at the corner comes into contact when the shoji is closed (Japanese Utility Model Publication No. 62-12798), etc. However, in the former case, the gap remaining between the tight material and the corner block has not yet been treated, and in the latter case,
Since the protrusion is located on the indoor side, rainwater easily enters the indoor side. Furthermore, in cases where corner blocks are used, it is often necessary to assemble the blocks at the same time as the sash frame.

In other words, in any of the conventional examples described above, it is difficult to improve the watertight performance of the lower corner of the horizontal rotating window.Furthermore, if the shoji is installed incorrectly and there is a gap in the lower corner, rainwater can enter from there. It is impossible to prevent this from happening.

Problems to be solved by this invention This invention improves the watertight performance of the lower corner of the horizontal axis rotating window, and even if there is a gap between the tight material corner on the shoji side and the sash frame corner, The challenge is to provide a watertight structure that can prevent rainwater from entering.

Means for Solving the Problem The tight material corner portion of the rotary shoji where the tight material of the lower stile and vertical stile are continuous comes into contact with the sash frame corner portion where the tight material contact portion of the lower stile and vertical frame of the sash frame is continuous. A shielding device having a shielding part extending from a position below the tight material contacting part to a position above this part is attached to the stile of the rotating shoji at the lower corner part of the horizontal rotating window.

The shielding device is attached with the shielding part on the outdoor side of the corner part of the tight material, and the shielding part shields the gap between the corner part of the sash frame and the corner part of the tight material.

Function: The shield uses its shielding part to block rainwater from entering through the gap in the lower corner of the horizontal rotating window.

Embodiment Figures 2 to 5 show the lower corner part 3 of a horizontal rotating window in which a rotating shoji 2 is attached to a sash frame 1. A lower frame abutting piece 8 as a tight material abutting part is formed to protrude from the middle of the outdoor side wall 7 of the rising part 5 with the outdoor side inclined low. A gap 9 is formed between the lower part of the lower frame abutting piece 8 and the drainage part 6.

The vertical frame 10 of the sash frame 1 is provided with a vertical frame abutting piece 12 as a tight material contacting part on the indoor side on the inner peripheral side of the wall 11 in the direction of view, and a protrusion 13 on the outdoor side thereof.

The lower frame 4 and the vertical frame 10 are connected by abutting the end face of the lower frame 4 against the vertical frame 10, and the vertical frame abutting piece 1
2 and the lower frame abutting piece 8 continuously constitute a sash frame corner portion 14.

When abutting the end face of the lower frame 4 against the vertical frame 10,
The portion of the vertical frame 10 where the vertical frame abutting piece 12 and the lower frame end surface of the protrusion 13 collide is cut out.

The lower stile 15 of the rotating shoji 2 has a hanging part 1 on the outside of the lower room.
6, a mounting groove 17 is formed on the inside of the room, and a lower stile tight material 18 is attached to this groove 17. Further, a draining fin 19 is protruded from the bottom surface of the hanging part 16 with the indoor side tilted low, and the draining fin 19 and the lower surface of the hanging part 16 and the lower stile 15 form a recess 20 in the lower part of the lower stile 15. It is formed.

As shown in FIG. 3, the vertical stile 21 of the rotating shoji 2 has grooves 23 for attaching the vertical stile tight material 22 on the indoor side, and mounting fins 25 for the draining material 24 on the outdoor side.
is formed. When the window is closed, the vertical stile tight material 22 contacts the vertical frame abutting piece 12 of the vertical frame 10, and the draining fins 19 contact the protrusions 13 of the vertical frame 10.

The lower stile 15 and the vertical stile 21 are connected to the vertical stile 21 and the lower stile 1.
The ends of the lower stile tight members 18 and the vertical stile tight members 22 are connected by abutting against each other.
As shown in the figure, they are joined by welding and are continuous, forming tight material corner portions 26.

When abutting the lower stile 15 against the vertical stile 21, cut out the lower part of the inner peripheral side wall 27 of the vertical stile 21 by an amount corresponding to the height of the lower stile 15, and cut the end face of the lower stile 15 as shown in FIG. The vertical stile 21 is abutted against the outer peripheral side wall 28. Therefore, the drainage fins 19 of the lower stile 15 also abut against this outer peripheral side wall 28. Note that the outer side wall 28
The lower part of the indoor side is notched to match the cross section of the recess 20 at the bottom of the lower stile 15 (FIG. 1).

When the rotating shoji 2 is closed, the tight material corner portions 26 abut against the sash frame corner portions 14. Further, although not shown, the rotating shoji 2 is also in contact with the tight material abutting portions of the sash frame at other locations so that the inside and outside of the room are watertight.

In FIG. 2, reference numeral 29 indicates a shielding device, which is attached to the lower corner portion 30 of the rotating shoji 2. That is, the shielding tool 29 includes a shielding part 31, a base part 32, and a mounting part 33, as shown in FIG. The attachment portion 33 is fixed. The base portion 32 has a size that closes a notch in the lower part of the outer peripheral side wall 28 of the vertical stile 21, and the shielding portion 31 closes against the lower frame when the rotating shoji 2 is closed, as shown in FIGS. 4 and 5. The lower frame abutting piece 8 is moved from the tight material corner portion 26 located at the top of the abutting piece 8.
It is large enough to span the gap 9 at the bottom.

That is, the shielding part 31 extends from a position below the tight material contacting part to a position above this part, and extends from the lower gap 9 to the upper part of the lower frame abutting piece 8, and has a margin for shielding the corner part. It has a certain structure.

Note that horizontal pieces 35, 35 are formed to protrude toward the indoor side from the upper and lower sides of the shielding portion 31 of the shielding device 29.

That is, the shielding device 29 is attached to the rotating shoji 2, and its shielding portion 31 is located on an extension of the attachment groove 17 in the lower stile 15 along the outdoor side surface (FIG. 4).

When the rotating shoji 2 is closed, at the lower corner part 30 of the shoji, the lower stile tight material 18 and the vertical stile tight material 22 are attached to the lower frame abutting piece 8 on the sash frame 1 side and the vertical frame as shown in FIGS. It comes into contact with the contact piece 12 . Also,
As shown in FIGS. 4 and 5, the shielding part 3 of the shielding device 29
1 is located from the lower gap 9 to the upper part of the lower frame abutting piece 8, and is located on the outdoor side of the tight material corner portion 26 where both the tight materials 18 and 22 are continuous, and between the sash frame corner portion 14 and the tight material corner portion 26. The gap between the parts should be shielded with sufficient margin.

Figures 6 and 7 show the position of the shielding part 31 in the shielding tool 29 from the outside when the shoji 2 is closed. The gap between the portion 14 and the tight material corner portion 26 is shielded from the outdoor side so as to cover a relatively wide area.

Therefore, the rainwater blowing toward the lower corner part 3 of the horizontal rotating window is blocked by the shielding part 31 of the shielding device 29 and cannot reach the gap between the tight material corner part 26 and the sash frame corner part 14. Even if the shoji 2 is installed incorrectly and there is a gap in the lower corner part 3, the generous shielding structure prevents rainwater from entering through this gap.

In addition, during strong wind and rain, rainwater that attempts to enter the gap 9 is first largely blocked by the shielding part 31 of the shielding device 29, and then collides with the back surface of the lower frame abutting piece 8 and is thus blocked. It does not reach the contact portion between the tight material corner portion 26 and the sash frame corner portion 14.

As in the illustrated embodiment, when the shielding device 29 is provided with horizontal pieces 35 on the upper and lower sides, when the rotating shoji 2 is closed, in addition to the above-mentioned action by the shielding part 31, the upper horizontal piece 35 tightens the vertical frame. The material 22 is pressed against the vertical frame abutting piece 12 to increase the degree of adhesion.
Furthermore, watertight performance can be improved.

Effects of the invention The watertight performance of the lower corner of the horizontal rotating window is improved.

Even if the rotary shoji is incorrectly attached to the sash frame and a gap is created in the lower corner portion, the watertight performance of this portion will not deteriorate due to the shielding structure having ample margin.

Since the shielding device is attached to the lower corner of the rotating shoji, it can be easily attached even after the horizontal axis rotating window has been assembled, resulting in good workability.
