Description

[Detailed explanation of the invention] This invention relates to a two-panel or four-panel soundproof sash. Specifically, the door edge surface of the outer shoji door stile is brought as close as possible to the doorstop frame to make the window opening wider. This is about the soundproof satsushi.

Traditionally, soundproofing sashes have been used in buildings that require airtightness and watertightness, but these soundproofing sashes are particularly designed for outer shoji door frames that have a sliding piece with a sloped surface on the door end. , because it engages with the outer shoji contact piece of the outer shoji door frame to pull the door frame toward the indoor side, the opening degree of the window is lower than that of a general sash that does not have such a pull piece. was somewhat limited. In order to widen this opening degree, Japanese Utility Model Application No. 55-168671 proposes that the tip of the outer shoji contact piece (guide part) of the outer shoji door stop frame be positioned closer to the door stop frame base wall than the tip of the airtight material holding piece. let me,
In addition, it is disclosed that the door edge surface of the outer shoji door edge stile is substantially flush with the tip of the airtight material holding piece, but in this case, the depth of the recessed part of the outer shoji door edge stile in the shoji opening/closing direction is shallow. , the engagement between the pull piece and the outer shoji contact piece becomes shallower, and when the shoji is closed and pulled, the indoor pressure becomes higher than the outdoor pressure, and when the outer shoji bulges toward the outdoor side, the pull piece and the outer shoji abut. The pulling engagement with the outer shoji door piece tends to come off easily, and when the engagement comes off, the outer shoji door tip stile directly contacts the outdoor side piece located on the outdoor side of the guide part of the outer shoji door stopper frame to prevent it from coming off. There was a risk of damaging the outer shoji door frame.

Therefore, in view of the above-mentioned problems of the conventional technology, the present invention provides a soundproof sash in which a pulling piece attached to the door edge surface of a door frame of an outer shoji is engaged with an outer shoji contact piece of an outer shoji door stop frame. and the tip of the outer shoji contact piece is located closer to the doorstop frame base wall than the tip of the airtight material holding piece,
In addition, in a soundproof sash in which the door edge surface of the outer shoji door frame is formed to be approximately the same as the plane including the tip of the airtight material retaining piece when the outer shoji is drawn, the opening degree of the window is widened. A piece to prevent the outer shoji from coming off is attached to the contact piece, and when the shoji is pulled in, the indoor pressure becomes higher than the outdoor pressure, and the outer shoji swells toward the outdoor side, causing the pull piece and the outer shoji contact piece to be pulled together. When the outer shoji door frame comes off, the outer shoji door edge stile does not come into direct contact with the outer shoji door frame to prevent it from coming off the window frame, and even if the outer shoji door frame is prevented from coming off, the outer shoji door frame may be damaged. This is an attempt to provide soundproofing that does not require noise.

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. In FIG. 1, reference numeral 1 denotes a window frame, which is composed of an upper frame 2, a lower frame 3, an inner shoji door stop frame 4, and an outer shoji door stop frame 5.

It is sufficient if it is located closer to the outer shoji door edge stile than 8a and closer to the door stop frame base wall 5a than the tip 17a (including the tip) of the airtight material holding piece 17.
In addition, the distance between the indoor side surface 18b of the outer shoji contact piece 18 and the flat surface of the indoor side surface 20b of the outer shoji removal prevention piece 20 (X in the figure) is the outer shoji door which will be described later. It is set to be approximately the same as the distance (Y in the figure) between the indoor side inclination starting point 36a on the inclined surface 36 of the pulling piece 35 attached to the leading stile 30 and the indoor side piece 30b of the outer shoji door leading stile 30. Further, this indoor side surface 20b has an inclined drawing surface 20c formed on its tip 20a side, which engages with the indoor side piece 30b of the outer shoji door tip stile 30 so that the drawing piece 35 moves toward the outer shoji contact piece 18. The outer shoji door edge stile 30 is smoothly drawn in prior to engagement with the outer shoji door frame 30.

Next, 21 to 23 are pressure contact surfaces 21a to 2
The airtight material for inner shoji is fitted into the airtight material fitting grooves 9, 13, and 16 so that 3a are located on the same plane. Approximately half of the fitting grooves 9 and 13 on the outer shoji door stop frame 5 side are not fitted. Also, 24-2

It is an airtight material for the outer shoji shoji that is fitted in the outer shoji frame, and is attached only to the part facing the outer shoji frame in the closed state, and is attached to approximately half of the airtight material fitting grooves 8 and 12 on the inner shoji door frame 4 side. Not yet.

Next, 27 is an outer shoji that frames an upper stile 28, a lower stile 29, an outer shoji door edge stile 30, and an outer shoji joining stile 31, and is fitted with glass 32.
The guide groove 33a of the guide piece 33 attached to the upper frame 2 is fitted into the outer shoji guide hanging wall 7, and the door roller 34 attached to the lower stile 29 is fitted onto the outer rail 11. The door edge surface 30a of this outer shoji door edge stile 30 is approximately the same as the plane including the tip 17a of the airtight material holding piece 17 of the door stop frame 5 when the outer shoji is closed and drawn (in this embodiment, the edge surface 30a is slightly 32, but preferably within about 2 mm from front to back about the plane.) This door surface 30
A plurality of (three in the embodiment) pulling pieces 35 are fixedly installed in the upper and lower directions, and each of the pulling pieces 35 is formed with an inclined surface 36 that engages with the outer shoji contact piece 18. ing. At the top and bottom of the outer shoji folding frame 31, there is a Japanese Patent Application Laid-Open No. 58-1998, which has already been filed by the applicant of the present invention.
A pulling cam 37 as disclosed in No. 178790 is attached and biased clockwise, and the upper and lower frames 2,
When one of the contact arms 37a hits the catches 38, 38 that are fitted into the airtight material fitting grooves 8, 12 of No. 3 and abutted against the end faces of the airtight materials 24, 25 for outer shoji, the other contact The contact arm 37b rotates counterclockwise and comes into contact with the outer rail 11 and the outer shoji guide hanging wall 7, thereby drawing the outer shoji joining frame 31 toward the indoor side. Further, a crescent holder 39 is attached to the outer shoji stile 31. Next, 40 is the upper stile 4
1. An inner shoji that frames a lower stile 42, an inner shoji door edge stile 43, and an inner shoji joining stile 44, and a glass 45 is fitted into the frame, and the guide groove 46a of the guide piece 46 attached to the upper stile 41 forms the upper frame. Door wheel 47 attached to the guide hanging wall 6 for the inner shoji of No. 2 and the lower stile 42
is fitted onto the outer rail 10. A pulling piece 35 similar to the aforementioned pulling piece 35 is attached to this inner shoji door edge stile 43. Internal shoji stile 44
A crescent 48 is attached to the frame 48, and although detailed illustrations are omitted, there is a crescent 48 in the inner shoji stile 44 which is linked to the locking operation of the crescent 48, as disclosed in the above-mentioned Japanese Patent Application Laid-open No. 58-178790. The inner shoji guide hanging wall 6 and the inner rail 10 are engaged with each other to draw the inner shoji 40 toward the indoor side, and at the same time, the outer shoji airtight material 21 of the upper and lower frames 2 and 3 at the joining part 2
A pulling device 50 is installed to close the gap created between 2, 24, 25 and the airtight material 49. Further, 51 and 52 are smoke return plates formed on the inner and outer shoji frames 31 and 44.

Next, the effect will be explained. Inner and outer shoji 40,
27 is closed and the crescent 48 is rotated in the locking direction to engage the crescent receiver 39.
The outer shoji 27 and 40 are drawn and moved toward the closing direction by the action of the crescent 48. Of these, due to the draw movement of the outer shoji, the inner and outer shoji door frames 4
The pulling pieces 35 of 3 and 30 abut the inner and outer shoji contact pieces 14 and 18, respectively, and the inner and outer shoji door edge frames 43 and 3
0 toward the indoor side. Further, due to the rotation of the crescent 48 in the locking direction, the pulling device 50 in the inner shovel sash 44 is actuated to draw the inner shoji sill stile 44 toward the indoor side. Furthermore, when the outer shoji 27 is moved to the completely closed position by the drawing movement of the inner and outer shoji 40, 27, the pulling cam 37 is engaged with the retainers 38, 38 of the upper and lower frames 2, 3. The abutting arms 37b engage with the outer shoji guide hanging wall 7 and the outer rail 11 by rotating counterclockwise to draw the outer shoji stile 31 towards the indoor side. Therefore, within
The outer shoji 40, 27 has its inner side surfaces pressed to the inner and outer shoji airtight materials 21 to 26, and the combined airtight material 49 is also crimped to the outer shoji combined frame 31, and is pressed by the pulling device 50. At the meeting section,
Inside the lower frames 2 and 3, airtight materials for outer shoji 21, 22, 2
The space between the window frame 1 and the inner and outer shoji 40, 27 is kept airtight by closing the space between the window frame 1 and the inner and outer shoji 40, 27.

In such an airtight condition, for example, if the indoor pressure becomes abnormally higher than the outdoor pressure, the inner and outer shoji 40, 27 will bend toward the outdoor side due to the pressure difference, and the outer shoji 27 in particular will bend to the outside. In the door frame 30, the inclined surface 36 of the pulling piece 35 fixed to the door edge surface 30a moves along the outer shoji contact piece 18, and the outer shoji airtight material 26 attached to the airtight material holding piece 17 moves.
There is a risk that the indoor side surface of the indoor side piece 30b of the door frame 30 may separate from the door frame 30, and the engagement between the inclined surface 36 and the outer shoji contact piece 18a may come off. This pressure difference occurs when buildings are crowded together, such as in a rezoned housing complex, and where adjacent buildings have windows facing each other across narrow passages.
When a strong wind blows through the passage, the pressure on the outdoor side of the window on the passage side becomes negative pressure, but as mentioned above, in the unlikely event that the engagement between the inclined surface 36 and the outer shoji contact piece 17 becomes disengaged. Piece 2 to prevent outer shoji from falling off
Since the indoor side piece 30a of the door edge stile 30 comes into contact with the door edge 30 and prevents it from moving further toward the outdoor side, the outer shoji door edge stile 30 does not immediately come off from the window frame 1, and furthermore, It will not damage the outside shoji door frame. In addition, in this embodiment, the distance between the indoor side surface 18b of the outer shoji contact piece 18 and the indoor side surface 20b of the outer shoji removal prevention piece 20 is set to First stile 30
Since the distance is approximately equal to the distance from the indoor side piece 30b,
As described above, even when the indoor side piece 30b of the door frame 30 is in contact with the outer shoji removal prevention piece 20, the inclined surface 36 and the tip 18a of the outer shoji contact piece 18 can be made to face each other, and the indoor side pressure When the pressure drops below the outdoor pressure, the inclined surface 36 is smoothly engaged with the outer shoji contact piece 18, and the outer shoji door edge stile 30 can be returned to its original airtight state.

As described above, the present invention positions the tip of the outer shoji contacting piece closer to the door frame base wall than the tip of the airtight material holding piece, and the door edge surface of the outer shoji door frame Since it is made to be approximately the same plane as the plane including the tip of the airtight material holding piece in the state, the opening degree of the window can be made as large as that of a general sash, improving the appearance and lighting, and making the interior and exterior airtight. It has the advantage of being able to Moreover, even if the tip of the outer shoji abutting piece is positioned closer to the doorstop frame base than the tip of the airtight material holding piece, the pulling piece of the outer shoji door edge stile is closer to the doorstop frame than the tip of the airtight material holding piece. Since the indoor side piece of the outer shoji door tip stile contacts the indoor side of the outer shoji removal prevention piece when it is slightly removed from the outer shoji contact piece, the indoor side pressure is reduced when the inner and outer shoji are pulled together. becomes higher than the outdoor pressure, the shoji swells outward, and the slope of the pull piece of the outer shoji door stile moves along the outer shoji contact piece, causing the pull piece to move away from the outer shoji contact piece. Even if it comes off, the indoor side piece of the outer shoji door frame will come into contact with the indoor side of the outer shoji removal prevention piece, and the outer shoji door frame will not touch the outer shoji door frame directly. You can prevent the outer shoji from coming off without damaging it. Also, the distance between the indoor side surface of the outer shoji removal prevention piece and the indoor side surface of the outer shoji contact piece,
Since the distance is set approximately equal to the distance between the starting point of the indoor side slope of the pulling piece and the indoor side piece of the outer shoji door stile, as the outdoor pressure increases (or the indoor pressure decreases), it moves to the outdoor side of the outer shoji. When the deflection is gone, the inclined surface of the pulling piece can be smoothly engaged with the outer shoji contact piece, and the outer shoji door edge stile can be returned to its original airtight state. Moreover, since an inclined pulling surface is formed on the tip side of the indoor side surface of the piece to prevent the outer shoji from coming off, the outer shoji door edge stile can be moved to the indoor side before the pulling piece is pulled, and the outer shoji will come off. Even if there is a prevention piece, it can be pulled smoothly.

Furthermore, even if it is possible to prevent the outer shoji from coming off when the indoor pressure is higher than the outdoor pressure, the distance between the indoor side surface of the outer shoji removal prevention piece and the indoor side surface of the outer shoji contact piece, Since the distance between the starting point of the indoor slope of the pull piece and the outdoor side piece of the outer shoji door frame is set approximately equal, when the indoor pressure drops, the inclined surface of the pull piece engages with the outer shoji contact piece. This allows you to restore the outer shoji door frame to its original airtight condition. In addition, since an inclined pulling surface is formed on the tip side of the indoor side surface of the piece to prevent the falling off, the outer shoji door edge stile can be moved to the indoor side before the pulling piece is pulled in, and the piece to prevent the falling off of the outer shoji can be moved to the indoor side. Even if there is a problem, it can be smoothly attracted.
