JPS5849335Y2 - Internally moving single sliding soundproof window - Google Patents

Description

[Detailed description of the invention] This invention relates to a single-swing soundproof window for office work that opens and closes a sliding door toward the indoor side of the window and is automatically sealed by inertia just by closing the sliding door.

Conventionally, in order to obtain a high soundproofing and airtight effect when closing a single sliding window, a Gremont lock or other special hardware was installed, and after the sliding door was closed, the special hardware was operated to pull the sliding door into the window frame. .

Therefore, firstly, it is necessary to install multiple pieces of expensive special hardware, which increases the equipment cost.Secondly, after closing the sliding door, special hardware must be operated to pull the sliding door, so the operation of closing the sliding door is complicated. It takes a lot of work to operate the hardware separately from the hardware, and it also takes a lot of effort to operate the special hardware, and the special hardware is likely to break down during long-term use. Thirdly, the special hardware is Since they are usually installed in a single location, they have the disadvantage that they are difficult to lock if they are installed at a high location, such as a smoke exhaust window.

In addition, conventional single-sliding windows are so-called single-sliding windows that can be opened and closed freely on the outside of the window, so replacing the glass or replacing the special hardware cannot be done without removing the sliding door. In order to remove the sliding door, the sliding door must be taken out to the outside before it can be brought into the room, so there is a risk of the sliding door falling, and it is not possible to clean the glass in the fitted part from the indoor side.

If you install a single sliding window vertically on the outdoor side of the window to create a single sliding soundproof window for office work, the above disadvantages can be eliminated, but even if it is sealed, some rainwater will still infiltrate. In some cases, drainage is difficult due to the in-house system.

In addition, single-sliding windows for office workers have a drawback in that the sliding door support strength against negative pressure is weak, and when negative pressure is applied, the load of the sliding door is concentrated on, for example, the crescent lock, causing play in the sliding door.

In view of the above points, this idea was developed to provide sliding door support strength sufficient to withstand large negative pressure, and to provide a sliding door support strength that can withstand large negative pressures, and for office work single-swing soundproof windows that are automatically sealed when the sliding door is closed. The purpose is to allow rainwater that has entered the joint to be easily removed.

Next, the implementation of this invention will be explained based on the drawings.

The window frame F has a fitting part a for fixing the glass plate G1 on the left half of the window frame on the outdoor side in the width direction, and a sliding door is provided on the indoor side part of the window frame extending over the entire length of the window frame in the width direction.

The upper, lower, left, and right edges of the thick glass plate G1 are fitted and fixed into the grooves 1γ through beads 1B, 19, 20, and 21, respectively.

22 is a frame 8 placed on the upper surface of the web 6 of the lower fixing part.
It is a cushioning material having the same length as , and is fixed to the lower edge of the glass plate G1.

The vertical frame J2 on the right in FIG. 1 has a square box part 23 integrally on the outdoor side part, and the indoor side surface of the square tube part 23 and the indoor side hanging wall 2 forming the upper fixing part a1. The indoor side surface, the indoor side of the rising wall 9 forming the lower fixing part a2, and the indoor side surface of the mullion P forming the mullion fixing part a4 extend on the same vertical plane, and the window frame F A sliding door support part continues in a rectangular shape along the periphery of the opening O formed in the outdoor side portion of the sliding door support part.

A backing W that protrudes toward the interior of each room and continues in a rectangular shape along the periphery of the sliding door support part is attached to each indoor side surface by fitting into a dovetail groove provided on the indoor side surface.

The sliding door fitting part has a guide groove b1 of a downward opening formed in the indoor side part of the upper frame H between the hanging wall 2 of the upper fixing part a1 and the indoor side hanging wall 24, and a rising edge of the lower frame S. The rail b2 provided between the wall 9 and the weir wall 25, the door stop wall b3 formed on the indoor side part of the left vertical frame J1, the indoor side surface of the square tube part 23 of the right vertical frame J2, and the room The upper end of the sliding door is fitted into the guide groove b1, and the door roller 34 is placed on the rail b2 and horizontally moved. It is held slidably.

When the sliding door is in the closed state as shown in FIG. 2, tapers are formed at four locations corresponding to the left and right of the upper end of the sliding door and the left and right of the lower end of the sliding door, which diagonally cross the direction of movement of the sliding door when closed. A guide piece that has a surface and is fixed to a window frame or sliding door (sign with a complement added to g), and a guide piece that is fixed to a sliding door or window frame and hits the tapered surface of the guide piece as the sliding door moves when closed. ,
A pulling means is provided which includes a projecting piece (symbol with a complement added to r) that is moved along the tapered surface and pulls the sliding door toward the outdoors together with the guide piece.

In the illustrated embodiment, the guide pieces are fixed to the window frame and the projecting pieces are fixed to the nine doors.

To explain in more detail, the sliding door is the upper stile 21 and the lower stile 2.
The webs 29a are attached to the left and right vertical frames 29, 30 at both longitudinal ends of the frame 8.

30a is adopted, the upper protruding piece r1 is attached to the upper end of the vertical stile 29, 30, and the lower protruding piece r2
are attached to the lower ends of the stiles 29, 30.

However, if the sliding door adopts a frame assembly structure in which both longitudinal ends of the upper and lower frames 27°28 are fitted to the outer walls 29b and 30b of the left and right vertical frames 29 and 30, the upper protrusion r1 and the lower protrusion The pieces r2 are attached to both longitudinal ends of the upper stile 21 and the lower stile 28, respectively.

Further, the upper guide piece g1 is the upper protruding piece of the sliding door when closed;
It is attached to the guide groove b1 of the upper frame H constituting the sliding door fitting part toward the position corresponding to □ so that the tapered surface is on the moving surface of the upper protrusion r1, and the tapered surface is facing outdoors.

The lower guide piece g2 is also moved to a position corresponding to the lower protruding piece r2 of the sliding door when closed, and the tapered surface is directed onto the moving surface of the lower protruding piece r2 on the rail b2 that constitutes the sliding door fitting part. It is installed so that it faces toward the outdoors.

The protrusions r12 r2 may be mere protrusions, but if they are protrusions, the tapered surfaces of the protrusions and guide pieces will wear out quickly due to frequent collisions with the kite piece gltg2, resulting in a decrease in airtightness and soundproofing performance. Therefore, as shown in Fig. 3, the bearing part 3 of the mounting plate 31 fixed to the sliding door frame is
It is preferable to use rollers 33 held at 2 and 32 so as to rotate freely.

Since the rollers 33 roll along the tapered surface of the guide piece,
It prevents wear of the guide piece and allows the sliding door to be opened and closed easily and smoothly.

The sliding door is further attached to the door roller 34 so that the lower end of the sliding door can be moved toward the outside while the door roller 34 is placed on the rail b2.

Such a door wheel 34 may be slidably supported in the axial direction on an axle (not shown) fixed to the lower stile 28, and as shown in FIG. A mounting plate 36 fixed to a part of the supporting door frame 35 and the lower stile 28
It is also possible to form a hinge with a part of the hinge and attach the door roller base 35 so that it can be rotated and tilted around the hinge part 31 of the hinge.

With the above-described configuration, when the inner sliding door is closed, the vertical stile 30 is stored in the storage groove b4 and just before it hits the vertical frame J2, the upper protruding piece r1 and the lower protruding piece r2 each touch the taper of the upper guide piece g1. Since it hits the tapered surface of the surface and the lower guide piece g2 and is guided along the tapered surface, the entire sliding door is pulled toward the outdoors from the position indicated by the dotted line in FIG. 1 to the position indicated by the solid line. , the outer peripheral surfaces of the sliding door, that is, the outdoor surfaces of the upper and lower frames and the left and right vertical frames are uniformly pressed into close contact with the backing W that is protruded from the sliding door support portion.

In other words, each pulling means uses the kinetic force and inertia force in the closing direction of the sliding door to retract the sliding door toward the outdoors, so that just by closing the sliding door, it is pulled around the entire circumference of the sliding door and tightly attached to the backing W. Provides soundproofing and airtight effects.

Therefore, unlike in the past, special hardware such as a Gremont lock is not required, and there is no need to operate a plurality of special hardware in addition to the work of closing the sliding door.

Since the pulling means has a simple structure consisting of a guide piece and a protruding piece, it can be manufactured and attached at low cost.

Therefore, the cost of window equipment is low, and it can be easily sealed.
Achieves high soundproofing and airtightness.

Furthermore, since the sliding door is built into the indoor side and is supported in contact with the sliding door support part, there is no possibility that the sliding door will be removed to the outdoor side even if it receives a large negative pressure.

Further, even if the sliding door receives negative or positive signals, it is firmly supported by the sliding door support portion, so even if the sliding door is locked with a crescent lock, for example, the crescent lock will not be deformed and will not play.

As mentioned above, in this invention, a rectangular continuous sliding door support part is provided on the outdoor side of the sliding door fitting part, and the closed sliding door is pressed against the backing protruding from the sliding door support part in the outdoor direction. Since the sliding door is made of 300 ml, it has good protection against rain, but due to gusts of wind during storms, a small gap may be created between the backing and the sliding door, allowing rainwater to enter.

In this invention, a drainage means is provided to deal with this infiltrated rainwater and allow it to be easily drained.

That is, the rail b3 of the lower frame and the rising wall 9 are raised from the flat substrate 39, and the groove 43 is formed by these rails, the rising wall and the substrate, and the groove 43 is formed between the rail b2 and the rising wall 9 from the bottom surface of the substrate 39. The bent board 44 is extended in the outdoor direction, the guide piece g2 of the lower frame is formed into an L shape, and is attached so as to dam the groove 43, and between the left and right guide pieces and the flat board 39 bending board 4
4 and the rising wall 9, there is a drainage hole 38.
is provided to allow rainwater that has entered the sliding door fitting portion to flow down into the groove 43 and to be discharged to the outside via the drainage hole 38 and the water drain hole 40.

Further, 41 is a backing attached to the lower end of the indoor hanging wall 28' of the lower stile S, and by closely contacting the rail b2 with the backing, noise and wind entering from the drainage hole 38 are absorbed from the lower stile 28. This prevents infiltration into the indoor side through the gap between the lower frame S.

As mentioned above, according to this invention, first, an opening is formed by the mullion attached to the fitting part, the upper and lower frames of the window frame, and the corner part protruding from the vertical bar. Therefore, the opening has great strength.

Second, around the opening, the hanging wall of the upper frame, the rising wall of the vertical bar, the interior side surface of the mullion, and the interior side surface of the corner section of the vertical bar are arranged on a common vertical plane. Since the sliding door support part is formed by continuous rectangular buttons on the top, the sliding door support part has a large support strength, and can not only completely withstand the pulling force of the pulling means toward the outdoor side, but also maintain the closed state. Even if a large load is placed on the sliding door, the sliding door is firmly supported and, for example, even when the sliding door is locked with a crescent lock, the crescent is prevented from being deformed and rattled.

Thirdly, since a rectangular continuous backing is attached to the indoor side surface of this sliding door support part, which protrudes toward the indoor direction,
Great airtightness and soundproofing effect when sealed.

Furthermore, fourthly, the rising wall of the lower frame and the rail supporting the sliding door rise from the flat base plate of the lower frame to form a groove therebetween, and the lower surface of the flat base plate has the rail and the rising wall. A bent substrate extending downwardly is provided between the flat substrate, and a drainage hole is provided in the flat substrate between the connecting portion with the bent substrate and the rising wall and toward the indoor side of the opening. Because we have installed a
The rainwater is collected in the groove and prevented from entering the room through the sliding door, and the water accumulated in the groove is easily drained outside through the drainage hole.

Furthermore, since the sliding door is built on the indoor side and is pulled toward the outdoor side when closed, it is possible to hold the sliding door with both hands when closing it, and therefore the tapered surface of the guide piece If the sliding door tries to return to the opening direction due to reaction force, you can prevent this by holding the sliding door with your hand, and easily lock the sliding door with a crescent lock, or, if necessary, use the kinetic force in the closing direction of the sliding door or It is possible to supplement the pulling force of the pulling means from inside the room.
