Description

[Detailed Description of the Invention] The present invention relates to a bay window that is renovated into at least a new and old double sash structure by attaching a new window frame from outside the building to an existing window frame installed in a window section of a building.

For example, when renovating a window to a double-sash insulation structure in consideration of the cold winter climate, conventionally the entire existing window frame was removed from the building and a new double-sash prepared frame was installed, which requires a lot of effort. In addition to requiring a lot of effort and expense, removing the existing window frame easily damages the building structure, and installing a new double-sash window frame requires repair of the building later.

Therefore, without converting the existing window frame to a new double-sash window frame, the existing window frame is left as is and used as the inner window frame in the double-sash window frame, and a new outer window frame is created for this inner window frame. It is proposed that the window frames be renovated into double-sash windows by connecting them from outside the building.

The present invention allows external window frames to be attached externally in such a double sash structure to easily absorb changes in the shape of existing window frames in individual buildings to which the window frames are installed, and to reduce the number of external window frame members as much as possible. This is an attempt to reduce manufacturing costs by standardizing them.

Hereinafter, one embodiment of the present invention will be described based on the drawings.
is an external window frame consisting of an outer frame 2 and an inner frame 3, and the outer frame 2 is made up of upper, lower, left, and right outer frame members 4a to 4c made of shapes having the same cross-sectional shape. -c are connected in a rectangular frame shape.

The outer frame members 4a to 4c are provided with a hanging wall part 6 at the front edge of a slanted wall 5, a connecting rib 7 and a connecting fitting fitting groove 8 are provided on the inner surface of the hanging wall part 6, and the slanted wall 5 is attached to the base of leg 9.
A connecting fitting fitting groove 10 is formed on the hanging wall surface of the leg portion 9, and a connecting rib 11 is provided at the center of the inner surface of the inclined wall 5. A plurality of screw pockets 12... are provided.

When constructing the outer frame 2 by connecting these outer frame members 4a to 4c, the outer frame members 4a and 4c, 4b and 4C are connected as shown in FIG.
At the right angle joint with the outer frame members 4a and 4c and 4b and 4C, fit both sides of the L-shaped connecting fittings 13 and 14 into the connecting fitting fitting grooves 8 and 10 of the outer frame member to make the outer frame members 4a and 4c and 4b and 4C at right angles. After positioning and joining and increasing the strength of the part, screw 15.
Connect the outer frame materials using ....

On the other hand, the inner frame 3 differs from the outer frame 2 in that the upper, lower, left, and right inner frame members 16a to 16c are formed from shaped members having irregular cross-sectional shapes.

In order to erect window sashes A and A in the inner frame 3 so that they can be opened and closed, rail strips 17a and 17b are provided on the upper and lower inner frame members 16a and 16b, and rail strips are provided on the left and right inner frame members 16c. This is because it is necessary to provide the door stop rubber fitting groove 18 instead of the material.

However, these inner frame members 16a to 16c are provided with a mounting piece 19 extending from the outer surface of the front edge as a common feature, and a weir wall portion 20 having a draining function at the rear edge.

Furthermore, abbreviated-shaped auxiliary metal parts 21, 22, 23 are added to the weir wall part 20 of each inner frame material 16a to 16c with screws 24, and these auxiliary metal parts 21, 22, 23 are attached to each inner frame material. Flange portions 25, 26.27 extend from 16a to 16C.

Among these auxiliary hardware items 21, 22, and 23, the upper inner frame material 16a
Connecting fitting fitting grooves 28, 29 protruding to the outside of the inner frame members 16a, 16c are integrally formed on the auxiliary fittings 21, 23 attached to the left and right inner frame members 16c.

The inner frame members 16a to 16c are assembled into a rectangular frame shape to form the inner frame 3 using the screw pockets 30 provided therein.

In this inner frame assembled state, the above-mentioned auxiliary fittings 21, 22, 23
The flange portions 25, 26, and 27 form a box-cylindrical ring.

In addition, the auxiliary parts 21, 22, and 23 are the inner frame members 16a to 16c.
It is also possible to integrally extrude the material.

This inner frame 3 is fitted into the outer frame 2, and is attached to the connecting rib 7 of the outer frame 2 by fastening the pieces 19 with screws 31.
1. Fit the connecting hardware 32 into the connecting hardware fitting grooves 28 and 29 of 23, and fasten the ends of the connecting hardware 32 to the connecting ribs 11 of the upper outer frame member 4a and the left and right outer frame members 40 with screws 33.
By doing so, the inner frame 3 and the outer frame 2 are fixed to form an external window frame 1.

Reference numeral 34 denotes an existing window frame installed in the window section of the building 35, and a portion of the window frame 34 protrudes to the outside by a slightly larger amount than the outer wall 36 of the building.

When attaching the above-mentioned new external window frame 1 to the outside of such an existing window frame 34 to create a double sash structure, first install the supporting metal fitting 37 horizontally directly below the existing window frame 34 on the building exterior wall 36. If multiple pieces are installed in one direction, fix them with bolts 38. Next, for external installation, stack the window frame 1 on the existing window frame 34 from the outdoor side.
At the same time, the box-cylindrical flanges 25, 26, 27 of the inner frame 3 are externally fitted onto the existing window frame protrusion 34a, and the above-mentioned support fittings 37 are inserted between the outer frame 2 and the inner frame 3. is window frame 1
After placing the weight of the outer frame 2 on the support fitting 37 via the inner frame 3, the outer frame 2 is attached to the outside wall 36 of the building by fixing the legs 9 with the mounting bolts 39 and attaching the flange 26 to the support fitting 37. The screw fixing 41 and the box-cylindrical flange portions 25, 26, 27 that are externally fitted to the existing window frame protruding portion 34a.
The gap between the two is watertightly closed with a filler 40 such as silicone.

As described above, a window with a double sash structure is obtained in which the existing window frame 34 is used as an inner window frame and the new external window frame 1 is used as an outer window frame.

As detailed above, the present invention does not make the window frame for external use a single frame structure, but for the external use, the window frame has a double structure of an outer frame and an inner frame, and the two frames are connected. Therefore, it can be applied to existing window frames of various shapes by simply replacing the inner frame.

In other words, since the shape of existing window frames varies widely depending on individual buildings, the shape of the external window frame should be changed for the external window frame in consideration of the connection between the existing window frame and the external window frame. Each window must be manufactured to match the shape of the existing window frame of each building to which it is installed.

However, as in the present invention, the external window frame has a double structure of an outer frame and an inner frame, and the inner frame is adapted to the existing window frame.
If the outer frame is fixed to the building exterior wall as an integral part of the cover of the inner frame, only the inner frame needs to be manufactured to match the shape of the existing window frame, and the outer frame can be made into a common component for economical usage. .

Similarly, when configuring external window frames into various types such as outward-opening windows, sliding windows, fixed windows, etc., all you need to do is select and use the inner frame according to the type, and the outer frame is a common component. can do.

In addition, this invention uses formwork with the same cross-sectional shape for the upper, lower, left, and right outer frame materials that make up the outer frame, so by sharing the above-mentioned outer frame and commonizing the outer frame materials, the external fittings can be made into the same shape as the window frame. Manufacturing costs can be significantly reduced.

Moreover, since the inner frame is provided with a sheath-cylindrical flange portion integrally or integrally connected with the inner frame, and this flange portion is externally fitted to an existing window frame protruding from the building exterior wall, this overlap can be avoided. After configuration, the boundary between the existing window frame and the new external window frame will be beautiful, and even if the amount of protrusion of the existing window frame from the building exterior wall changes in size, the amount of change will be adjusted between the flange part and the existing window frame protrusion. Since it can be absorbed by the overlapping structure with the parts, the range of application is widened.

Also, as is clear from this overlap configuration, the existing window frame and the new external window frame are separated from each other in terms of material, so there is no heat conduction between the existing window frame and the external window frame. , it has excellent heat insulation effect.
