BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sash made of synthetic resin, which has improved heat insulation and dew-proof properties and is manufactured for use in cold regions.

[0002]

2. Description of the Related Art For example, sashes used in cold regions such as Hokkaido and the Tohoku region are required to have high heat insulating properties so as not to allow indoor heating in winter to escape to the outside. A structure that can prevent dew condensation due to a difference is required.

In recent years, as a response to these demands,
The material that composes the window frame and shoji frame of the sash is made of synthetic resin such as hard vinyl chloride from general aluminum alloy, etc.
Further, a glass having a double-glazing structure is provided.

[0004]

The shoji frame or window frame of the synthetic resin sash is usually manufactured as a single member having a hollow structure by extrusion molding, and is formed into a frame by assembly. At that time, the corners (corners) are connected by cutting both ends of each single material at 45 ° and pressing and bonding by heat welding, so that a closed space is formed inside the frame material. Therefore, particularly in the summer when the sunshine is severe, when the sash outer surface is directly insolated, the temperature inside the sealed frame increases, and the internal pressure increases, so that the thickness of the frame is thin,
Alternatively, there were cases where swelling or deformation occurred in a structurally weak part. In some cases, swelling or deformation of the frame material may cause problems such as poor tightening of the shoji and poor appearance. In recent years, due to demands for discoloration prevention and decorativeness, when a color finish is applied to brown or black, heat absorption is increased, and further, swelling or deformation of the frame material is easily induced.

Therefore, a main object of the present invention is to provide a sash made of synthetic resin in which the swelling and deformation of the frame material due to the influence of solar radiation heat are prevented.

[0006]

An object of the present invention is to provide a hollow structural member made of a synthetic resin material by joining both end surfaces thereof to communicate with each other.
In a synthetic resin sash configured using a window frame and a shoji frame assembled so that vacancies are continuous in four circumferential directions ,
The problem can be solved by forming a ventilation hole through which the hollow chamber and the outside air communicate directly or indirectly in the frame material of the window frame and / or the shoji frame.

In forming the ventilation holes, it is not always necessary to directly or indirectly communicate all of the hollow chambers formed in the frame material with the outside air. It is also possible to form a ventilation hole that directly or indirectly communicates with the outside of the hollow chamber adjacent to the frame member portion that directly contacts the outside. In addition, when the cross-sectional dimension of the hollow chamber is small, for example, since it has sufficient strength, it may not be necessary to form the ventilation hole. Also,
From the measure of the intrusion of water from the ventilation hole, the upper frame is provided with a ventilation hole for communicating with a partition partitioning between the hollow chambers without providing a ventilation hole directly communicating with the outside, and the lower frame has a hollow chamber. Fresh air
Vent holes that directly or indirectly communicate with each other can also be formed. In this case, the vent hole of the lower frame also serves as a drain hole for dew condensation water and intrusion water.

The term "indirectly" in the present invention means that one hollow chamber communicates with the outside via another hollow chamber.

[0009]

According to the present invention, since a synthetic resin frame member is provided with a ventilation hole through which the hollow chamber inside the frame member communicates with the outside air, the air expanded in the hollow chamber due to the solar radiation heat is supplied to the outside through the ventilation hole. As a result, the pressure in the hollow chamber does not increase and the swelling and deformation of the frame material can be prevented.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to embodiments shown in the drawings. FIG. 1 is a vertical sectional view of the casement window, FIG.
3 and 4 are enlarged views of a main part. A window frame 1 made of a synthetic resin such as a hard vinyl chloride resin material is attached to a window frame 1 made of a synthetic resin such as a hard vinyl chloride resin material by extrusion or the like. I have. The shoji 2 is rotatably supported by a hinge 4, and the upper frame 2A is provided with a tilt stop 3 connected to the window upper frame 1A. The frame members 1A to 1D constituting the window frame 1 are extruded into a hollow structure, and the ends are joined by heat welding to form a frame. Therefore, as the initial structure, the hollow chamber is a continuous space in the four circumferential directions and a closed space. Note that the frame members 1A to 1D usually have a multi-chamber structure having a partition wall for reasons of extrusion formation and strength. As shown in FIG. 3 in detail, before the window frame 1 is installed, in order to prevent the pressure of the hollow chamber from increasing due to direct solar radiation after the window frame 1 is installed in an opening of a building or the like. In addition, a ventilation hole in which the hollow chamber in the frame member 1 communicates directly or indirectly with the outside air is formed. In the first specific example, a hole drill having a diameter of, for example, about φ2 to φ5 mm is formed by a single drilling so as to penetrate the hole 1a and the hole 1b, and further, the hole 1c and the hole 1d are drilled once. It is drilled by. In the hollow chambers P ₁ and P ₂ in the hollow chamber group of the frame material 1, the ventilation holes can be omitted because the influence of the solar heat is relatively small. Reference numeral 11 denotes a groove cover provided regardless of the formation of the ventilation holes 1a to 1d.

The upper frame 1A should preferably be drilled at one location for preventing water intrusion, and this is sufficient to release the inflation pressure in the hollow chamber. At the time of mounting, the hole 1a is preferably set so that intrusion water or the like from a wall does not flow.
After the perforation, it is preferable to seal off with a caulking material or a sealing tape.

On the other hand, the lower frame 1B is described in detail in FIG.
As shown in (1), a hole 1e and a hole 1f are formed to communicate the hollow chamber with the outside air. It is preferable to provide a plurality of locations in the lower frame 1B at appropriate intervals in consideration of discharge of dew condensation water and intrusion water in the hollow chamber. Specifically, it is preferable to provide two to five places in one window, and about two to three places in consideration of aesthetics and the like.

[0013] Shoji 2, in order to ensure high insulation performance, together with the glass G ₁ and the glass G ₂ is configured as a double-glazing structure fitted, the four sides surfaces of the glass G _1, G _2, Tight material 23, 23 having a plurality of contact pieces
… Ensures high air and water tightness. In addition, 2
Reference numeral 1 denotes a ledge for attaching the glass G ₁ or G ₂ . In addition, tight materials 12, 22,... Are provided to seal the gap between the shoji 2 and the window frame 1 and to ensure airtightness and watertightness. With respect to the frames 2A to 2D of the shoji 2, only the lower frame 2B is used to discharge the dew condensation water and the intrusion water in the hollow chamber.
Holes 2a to 2e are formed. When drilling, for example, φ
With a hole drill of about 2 to 5 mm, the holes 2a to 2c are formed so as to penetrate the holes 2a to 2c to form a single hole.
The hole 2e is formed by a single perforation. In addition, it is good to make a plurality of perforations like the window frame 1. Note that the hollow chamber P _3, the gap communicates with the outside formed in 5 parts of the handle, it is possible to release the inflation pressure, it is possible to omit the vents. As for the hollow chamber P _4, facing the interior side, because the increase in temperature and internal pressure is small, it does not form a communication hole with the outside air.

On the other hand, as another method of forming the above-described communication hole, for example, as shown in FIGS.
Prior to joining the frame members 1A and 1D, notches 1g and 1h are provided in partition walls partitioning the hollow chambers at the end portions of the frame material obliquely cut at 45 °, and then the notch portions 1g are thermally welded. , 1h can be a communication hole. The notch is preferably formed in both frame members 1A and 1D, but may be formed only in one of the frame members. In addition, not only the communication hole formed in the partition wall for connecting the hollow chambers as described above, but also the communication hole formed in the outer peripheral wall such as the communication hole 1f may be formed by the same method. Can be. The size of the notch needs to be such that the communication hole can be reliably formed without being blocked by thermal welding. In addition, it is also possible to form a communication hole in a shoji frame by the same method.

Next, as a second specific example, a case of a sliding shoji will be described with reference to FIGS. A window sash 6 made of a synthetic resin such as a hard vinyl chloride resin material and a sliding sash 7 and 8 made of a synthetic resin such as a hard vinyl chloride resin material is used for a window frame 6 manufactured by extrusion and the like. Is fitted. First, with respect to the window frame 6, the upper frame 6A is drilled once from the back side using a hole drill having a diameter of 2 to 5 mm so as to penetrate the upper frame 6A.
a, 6b and 6c are formed, and the hole 6a is closed with a caulking material or the like. For the lower frame 6B, a hole 6d is formed in a rising piece of each rail for discharging rainwater or the like.
6e and 6f, 6g and 6h. further,
The hollow chamber of the frame member 6 communicates with the outside air to release the inflation pressure, and the vent holes 6i,
6j. As in the first specific example, it is preferable that the perforated portion is one for the upper frame 6A and a plurality of portions for the lower frame 6B.

On the other hand, regarding the shoji screens 7 and 8, the lower frame 7B,
Since the gaps 7a and 8a formed in the door rollers 71 and 72 attached to 8B communicate with the outside air,
It is not necessary to form a ventilation hole.

[0017]

As described above in detail, according to the present invention, since the ventilation hole for communicating the hollow chamber and the outside air is formed in the synthetic resin frame material, the air expanded in the hollow chamber due to the solar radiation heat is generated by the above-mentioned method. Since the frame material escapes to the outside through the ventilation hole, swelling or deformation of the frame material does not occur.
