Description of the Related Art In recent years, a composite type sash window frame having a resin frame on an exposed portion on the indoor side of a window frame formed of a metal frame such as an aluminum sash has been used. This is because the indoor side of the metal frame is covered with a resin whose thermal conductivity is extremely low compared to metal, thereby improving the heat insulation of the sash window and suppressing condensation on the indoor side. The aim is to improve the design by eliminating the coldness and at the same time integrating it with the interior decoration. Such a composite type sash window frame is installed in a window opening with a resin frame attached to a metal frame and the window frame completed.

排除するという効果が不十分であった。However, in the conventional composite-type composite sash window frame, even if a resin frame is attached to an exposed portion on the indoor side of a window frame made of a metal frame such as an aluminum sash, it is originally required. It was difficult to completely achieve the purpose of the above. That is, even if the resin frame is attached to the aluminum lower frame, a part of the aluminum lower frame covered with the resin frame may transfer heat to the decorative frame of the window opening, for example, between the rails of the lower frame. In such cases, the resin frame cannot be attached to the entire surface due to the complicated structure, and therefore,
The effect of preventing the dew condensation by improving the heat insulating property, which is the original purpose of the composite window frame, and eliminating the visual coldness of the metal frame was insufficient.

In addition, when the interior decoration is changed in order to give the resin frame integrity with the interior decoration, the resin frame may need to be replaced at the same time according to the interior decoration. However, conventionally, even when the resin frame is replaced, it is necessary to remove the entire window frame including the metal frame from the window opening, and there is a problem that workability is extremely poor.

As a composite window frame, the heat insulation is improved to sufficiently prevent dew condensation, and the visual coolness of the metal frame is reduced. The purpose is to provide a lower frame of a composite sash which eliminates and exhibits a sufficient design effect. It is another object of the present invention to make it possible to replace only the resin lower frame while the window frame is installed in the window opening, thereby improving the maintainability of the composite sash window.

a and the standing piece 41 which is in close contact with the inner side surface of the lower inner rail 22b.
b and an inverted L-shaped angle piece 41c provided along the rising piece 22c. A hanging piece is provided on the indoor side of the hollow portion of the frame body 41a, and a locking portion at the lower end thereof is locked with a projection 22g provided on a rising piece 22c of the aluminum lower frame 22. The lower inner rail 22b is in contact with the indoor surface of the lower inner rail 22b so as to overlap with the inner surface of the lower inner rail 22b, and the leading end thereof is engaged with the upper end of the lower inner rail 22b.
An outdoor frame is formed on the outdoor surface of the window frame 2c so that the outdoor side piece is in contact with the outdoor side and the indoor side piece is protruded toward the indoor side.
A is attached so as to be in direct contact with the upper surface of A. As a result, the first resin frame 41, which is the first resin frame, is detachably attached to the entire aluminum lower frame 22 in the expected direction without using screws or the like. It is. When attaching the main resin frame 41 to the aluminum lower frame 22, the frame main body 41 a is press-fitted into the concave groove of the aluminum lower frame 22, and the locking portion is locked to the projection provided on the aluminum lower frame 22. Let's make the aluminum bottom frame 2
2 is elastically fixed.

The surface is indirectly in contact with a vertical surface on the outdoor side via a resin auxiliary frame 42 described later without contacting the surface of the decorative frame 60A. The angle piece 4 of the main resin frame 41 adhered to the rising piece 22c.
The horizontal plane, which is the indoor surface of 1c, has the rising frame 22c, that is, the decorative frame 60A without the aluminum metal part.
Directly in contact with the surface. As a result, the resin material having a low thermal conductivity abuts on the decorative frame 60A on the indoor side to suppress the heat conduction from the outside air to the indoor, thereby significantly increasing the heat insulating effect. In addition, the standing indoor surface of the rising piece 22c is
The decorative frame 60 </ b> A may directly directly contact the vertical surface on the outdoor side.
