DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bay window which has a front portion and left and right sleeve portions projecting from an opening of a building frame and has a heat insulating function on a base plate provided thereunder.

[0002]

2. Description of the Related Art Since a conventional bay window is not provided with an aggressive heat insulating function, the consumption of heating energy particularly in the winter season increases. It has been proposed that a pair of glasses be fitted into the windows of the front and sleeve portions, a heat insulating material made of a foam material be provided on the ceiling, and a heat insulating material be provided on the base plate. As an example,
Japanese Unexamined Patent Publication No. 4-323486 is known, and the heat insulating means of the base plate portion described in the above publication has a base plate provided below the base plate, and a heat insulating material is filled between the base plate and the base plate. The bottom plate has a base portion fixed to a frame via a bracket, and a frame attached to a tip portion.

[0003]

As described above, the means for providing a space between the bottom plate and the base plate and filling the space with a heat insulating material is a commonly used means. The mounting procedure is such that a bottom plate is first mounted, a frame is provided on the bottom plate, a heat insulating material is placed on the bottom plate, and then the main plate is mounted. By the way, the above-mentioned bottom plate is an important member which receives the load of the frame in the invention of the above-mentioned publication, and it takes time and labor to assemble the frame to the bottom plate, and after placing the heat insulating material on the bottom plate. Attach the base plate so that it is inserted from the indoor side.In that case, the heat insulating material is inserted while compressing the heat insulating material with the base plate, so the heat insulating material slips during insertion or gets caught in the mounting part between the main plate and the frame From
Careful attention is required when inserting the main plate, and there is a problem that it is difficult to attach.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems. Even if heat insulation is applied to the main plate, the main plate can be easily assembled to the frame of the bay window. It is an object of the present invention to provide a bay window having a configuration capable of obtaining a reinforcing action.

[0005]

Means for Solving the Problems A solution according to the present invention is to provide a bay window having a frame formed by a front portion and left and right sleeves provided from an opening of a building frame. On the indoor side, there is a concave groove that opens toward the indoor side, and the base plate is inserted and locked in the concave groove,
A heat-insulating plate is bonded to each of the portions protruding from the skeleton on the rear surface of the base plate and divided into right and left parts by brackets protruding from the skeleton and receiving the base plate.

Further, the heat insulating plate is formed by cutting a portion protruding from the skeleton of the main plate, and furthermore, by a bracket receiving the main plate protruding from the main body and divided into right and left portions according to the size of each portion. It is characterized by the following.

[0007]

In the bay window of the present invention, a heat insulating material is adhered to the left and right portions on the back surface of the base plate. In this case, the bracket protruding from the skeleton abuts on a portion of the back surface of the main plate where no heat insulating material is provided.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A bay window according to the present invention will be described in detail. As shown in FIG. 1A, a frame 1 of a bay window has a front section 2 and two sleeve sections 3 and 3 having a cross-sectional shape. It has a trapezoidal shape.
As shown in FIG. 2, an upper piece 5 and a lower piece 6 project in parallel with each other toward the indoor side over the front part 2 and the left and right sleeves 3 and 3 on the indoor side of the lower frame 4 of the frame bone 1. And the upper and lower pieces 5,
6, a concave groove 7 is formed therebetween. This groove 7
The outer peripheral edge of the base plate 8 is fitted into the base plate 8, and after the base plate 8 is fitted into this, the upper piece 5 is used for screwing.

As shown in FIG. 2, the base plate 8 is made of wood and has a size to be mounted on the window base 10 of the building frame 9 in addition to the size of the bay window. On the other hand, as shown in FIG. 4, a bracket 17 protrudes from the window sill 10 toward the outside of the room, and this bracket 17 is in contact with and supported by the back surface of the base plate 8. Of the partial range protruding outside the window from the window sill 10,
The heat insulating plate 11 is adhered by an adhesive over substantially the entire length of the left and right portions thereof, avoiding the portion where the bracket 17 comes into contact. When the base plate 8 to which the thermal cutting board 11 is adhered as described above is inserted into the groove 7 of the frame bone 1, the tip of the heat insulating plate 11 is not interfered with the lower piece 6 forming the groove 7. To
An escape groove 12 is provided in the heat insulating plate 1 so that the lower piece 6 can be fitted with a margin.

The heat insulating plate 11 is obtained by cutting a fixed heat insulating material such as a polystyrene foam plate, a rigid urethane foam plate or a styrene foam plate into a required size and shape. When the heat insulating plate 11 is bonded to the base plate 8, an adhesive may be used as described above, or a double-sided adhesive tape may be used.

The ground plate 8 to which the heat insulating plate 11 is attached is
When this is attached to the frame 1 for the bay window, which has already been assembled, when it is attached to the frame 9, it is inserted into the concave groove 7 from the open side, which is the indoor side, and screwed in as described above. After the base plate 8 with the heat insulating plate 11 is attached, a parting member 13 for covering the indoor side end surface of the heat insulating plate 11 is attached. When the parting member 13 attaches the frame bone 1 to the frame 9, , To be screwed to the window stand 10.

As shown in FIG. 2, there are two types of bay windows: one having a base wheel 14 and the other, not shown, but not having a base wheel. Since the base plate 14 is provided with the bottom plate 15, the heat insulating plate 11 attached to the base plate 8 cannot be seen from the outside, but if there is no base plate, it can be seen from below, especially on the second floor. Those that are provided at a high position are easy to see and impair the appearance.

As described above, in the case of a bay window having no base wheel, as shown in FIG.
It is preferable that a decorative plate 16 such as an aluminum plate is stuck thereon.

[0014]

According to the bay window according to the present invention, the heat insulating plate is attached to the back surface of the base plate provided on the lower frame of the bay window frame bone so as to avoid the area where the bracket protruding from the frame abuts.
Moreover, the frame provided with this ground plate is attached to the skeleton, and at this time, the portion where the bracket abuts has a space where the heat insulating plate is not attached, so that the heat insulating plate does not hinder it. It can be easily attached to the frame.

As described above, the heat insulating plate is first attached to the base plate and attached to the frame bone, and the frame bone is mounted to the skeleton. The heat insulating plate covers a portion of the base plate exposed to the outside from the standard heat insulating material. Because it is formed and adhered to the size, even if the bracket protrudes, it can reliably cover the part facing the outside of the base plate, and even if it is pre-attached to the heat insulation plate, the heat insulation effect on the base plate will be ensured Something that can be kept.
