Description

[Detailed description of the invention] The present invention relates to a window frame made of synthetic resin.

The synthetic resin window frames described above are often used, especially in cold regions, because they have superior dew condensation resistance, corrosion resistance, and soundproofing properties, and have less heat loss than aluminum window frames.

Its structure uses a rod-shaped material made by extruding general K PVC resin into rod-shaped shapes through an extruder and a die for irregular cross-sections.The rod-shaped material is cut at a 45-degree angle to the required length to form a frame. It has a structure in which the frame sides are glued, welded, etc., and the four corners are stretched together to form a frame. Therefore, the work required by the frame work must be careful and accurate, requiring a great deal of labor and skill.Also, machining of the frame edges, etc. also required time and effort, and conventional window frames had the problem of extremely poor productivity. . Furthermore, in the case of an inner window frame into which a window glass is installed, the window frame is made by combining several types of members in order to attach the window glass, which further reduces productivity.

The present invention was made in view of the current situation, and an object of the present invention is to provide a window frame with good productivity.

That is, the present invention is a window frame characterized by comprising an integrally molded frame made of synthetic resin. In particular, when integrally molded by injection molding, continuous production is possible and productivity is significantly improved.

The following figure illustrates the present invention using a single-hinged window as an example. [K explains.

FIG. 1 is a plan view of the above embodiment, and FIG. 2 is a sectional view of the embodiment.

As shown in the figure, the single-hinged window is composed of an outer window frame Zoo attached to a wall (not shown) and an inner window 200 attached to the inside of the outer window frame 100 with a hinge 300 so as to be able to swing freely.

The outer window frame Zoo is made of PVC integrally molded by injection molding.
This is shown from an outer window frame 101 made of resin.

In other words, the outer window frame 10 has a thin wall structure with a substantially U-shaped cross section.
1, a mounting edge 10 protrudes outward from the front side (left side in the figure) of the outer window frame 101 for attachment to a wall.
2, the outer thin wall portion 101m is extended to the rear side (to the right side in the figure) to form a partition edge 103 for partitioning the wall, and the frame body has a cap 104 protruding inward on the rear side. The whole body has a thin wall structure, which allows for rapid cooling during molding, and is suitable for high-speed injection molding that can be molded with a left-right split mold, and is integrally molded by injection molding. In addition, the rear one-way window 200 of the inner window 200 at 10'5 in the figure has the following configuration. Reference numeral 201 in the figure indicates an inner window frame having a size to fit inside the outer window frame 100, and like the outer window frame 100, it is integrally molded from K PVC resin by injection molding.

Similarly to the outer window frame 102, the inner window frame 201
A has a thin-walled structure with a roughly U-shaped cross section, and based on this, insert a glass holder fi20 to the inside of the rear side by an appropriate width.
The hill portion 2 is designed so that the locking member 202, which will be described later, can be stored without interfering with the assembly work.
It has a frame structure in which 01e is formed. That is, like the outer window frame 100, the inner window frame 200 has a thin wall structure as well as the basic inner window frame 201m as a whole, and is suitable for high-speed injection molding that can be molded with a left-right split mold. It is integrally molded by injection molding.

The locking member 202 is made of the same PVC resin, and has a hill portion 201e along the entire inner circumference 1c of the inner window frame 201 as shown in the figure.
It is assembled on top and fixed with adhesive. The locking member 202 is a groove-shaped member that opens inside the inner window frame 201, and has locking claws 202m and 202b facing each other on both sides of the entrance thereof.

A body 204 made of neoprene 2 that fixes the position of the window glass 203, which will be described later, is glued to the inside of the hill 201e on the bottom side (lower side in the figure) of the inner welded frame 201. There is. In addition, the glass receiving edge 201b of the inner window frame 201
A buffer member 205 made of 7 ohm polyethylene is bonded to the front surface of the housing over the entire circumference.

The window glass 203 is made up of two glass plates 203 at a predetermined interval, the periphery of which is fixed by asphalt pitch 203 &
b, 203a, double glazed glass, as shown,
It is positioned by the positioning member 204 and assembled onto the buffer member 205 .

A buffer member 206 is provided on the front side as well as on the rear side, and suppressing members 207m, 207b, 20 full 1207
Fixed by d.

That is, the pressing members 207a, 207b, 2'O? e.

207d has a rectangular tube structure as shown in the figure, and has protruding sides 208m and 208b that engage with the locking claws 202m and 202b of the locking member 202 on one side. , 208b are engaged with the locking claws 202m, 202b of the locking member 202, and the window glass 203 is fixed. Therefore, since the window glass 203 is fixed at the front and back through the buffer members 205 and 206 which are made of elastic material, it will not be damaged even in the event of an earthquake or the like. In addition, when removing the rock, the suppression members 207m, 207b, 20
While strongly pressing 7e and 207d, remove the protruding sides 208m and 20
8b from the locking member 202.

209 in the figure is a sealing member consisting of a silicone sheet, which is applied evenly over the entire circumference.

The sealing member 209 only needs to be able to block rain and wind, and an elastic sealing material or the like can also be used. Moreover, 210 in the figure is a cover plate made of PVC resin that covers the hollow part of the inner window frame 201m and is fixed to the inner window frame 201a by adhesive to reinforce the inner window frame 201m.

It is effective in improving heat insulation and aesthetics.

A drainage hole 211 is provided at the bottom of the cover plate 21G to drain rainwater etc. from drainage holes 212m and 212b provided at the bottom of the inner window frame 201a (lower side in the figure). .

Assembling the inner window 200 from the above configuration is very simple as follows. That is, a drainage hole 212m is provided at the bottom of the inner window frame 201 integrally formed by injection molding.

212b is drilled, and then the locking member 202 and the positioning member 204 are adhered to each other to produce a basic framework. On the other hand, a buffer member 2051 and a glass 20 are attached to the basic framework to which the locking member 202 and the positioning member 204 are fixed.
3. Adhesive is applied around the buffer member 206 and stacked one after another as shown in the figure, and then the pressing members 207m, 207b,
Attach and secure 2117c and 207d. and,
Assembly is completed by applying silicone sealant as the seal member 209. As described above, the necessary parts are simply assembled one after another into the integrally molded inner window frame 201, and accurate positioning is not required. Therefore, the work is very simple, the number of assembly steps is small, and the productivity is therefore very high. improves. Moreover, the windows themselves are standardized, and it is clear that the above-mentioned simplification of assembly operations facilitates mechanization of assembly operations.

By the way, as described above, the outer window frame 1001 and the inner window frame 201 of the inner frame 200 are integrally molded by injection molding. The method for manufacturing the inner window frame 201 will be described below as an example.
