Abstract

PROBLEM TO BE SOLVED: To provide an upper frame having large rigidity of an indoor side rail part, having a small depth dimension and being excellent in an outward appearance of an internal appearance. SOLUTION: A first resin frame 30 is brought into with an indoor side part inside surface of a horizontal plate 21 of a metallic frame 20. A vertical piece 52 of a metallic reinforcing member 50 is brought into contact with an indoor side surface of a second downward piece 32 of this first resin frame 30 to form an indoor side rail part B to increase rigidity as well as to reduce a depth dimension. The metallic reinforcing member 50 improves an outward appearance of an internal appearance by making the member invisible from the inside of a room by contacting a vertical piece 45 of a second resin frame 40 with an indoor side surface of the vertical piece 52.

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal frame made of aluminum or the like, vinyl chloride, acrylic resin, PVC resin, FR
The present invention relates to an upper frame of a sash window frame formed of a composite sash material in which resin frames such as P resin and GRP resin are combined.

[0002]

2. Description of the Related Art As an upper frame of a window frame for a sash window made of a composite sash material, for example, the one shown in Japanese Patent Application Laid-Open No. 11-13343 is known. The upper frame covers a metal frame, a resin frame that covers the inside surface of the indoor portion of the metal frame, and has a downwardly facing piece, and a metal that is screwed to the indoor side inside surface of the resin frame and contacts the indoor side surface of the downwardly facing piece. It is formed of a reinforcing member. Since the upper frame forms the indoor rail portion for guiding the sliding door with the downwardly directed piece of the resin frame and the metal reinforcing member, the expected size of the indoor rail portion is small and the rigidity is large. Can be reduced.

[0003]

Since the upper frame has a metal reinforcing member in contact with the indoor side surface of the downwardly-facing piece provided on the resin frame, the metal reinforcing member is visible from inside the room, and the appearance of the interior is deteriorated.

Accordingly, an object of the present invention is to provide an upper frame of a sash window frame which can solve the above-mentioned problem.

[0005]

According to a first aspect of the present invention, there is provided a metal frame, a first resin frame having a downwardly facing piece, a second resin frame, and a metal reinforcing member, wherein the first resin frame is a metal frame. The metal reinforcement member covers the inner surface of the indoor side portion of the
The second resin frame is mounted in contact with the indoor side surface of the downward piece of the resin frame, the second resin frame is mounted in contact with the indoor side surface of the metal reinforcing member, and the rail portion is formed by the downward piece, the metal reinforcing member, and the second resin frame. It is an upper frame of a window frame for a sash window.

According to a second aspect of the present invention, in the first aspect, the second resin frame has a horizontal piece and a vertical piece, the metal auxiliary member has a horizontal piece and a vertical piece, and a second piece is provided on an inner surface of the metal frame. 1 resin frame touches,
The horizontal piece of the metal reinforcing member contacts the inner surface of the first resin frame, the vertical piece contacts the indoor side surface of the downwardly facing piece, the horizontal piece of the second resin frame contacts the inner face of the horizontal piece of the metal reinforcing member, and the vertical piece. Is in contact with the inside surface of the vertical piece of the metal reinforcing member, and the metal frame, the first resin frame, the horizontal piece of the metal reinforcing member, and the horizontal piece of the second resin frame are overlapped and connected by screws. This is the upper frame.

According to a third aspect of the present invention, there is provided a metal frame provided with a downward piece closer to the outdoor, and a first frame provided with a first downward piece and a second downward piece.
A resin frame, a second resin frame, and a metal reinforcing member, wherein the first resin frame is such that the second downward piece is in contact with the indoor surface of the downward piece of the metal frame; A downward-facing piece and a second downward-facing piece form an outdoor rail part for guiding a sash, and the metal reinforcing member is mounted in contact with an interior surface of the first downward-facing piece of the first resin frame. The second resin frame is attached in contact with the indoor side surface of the metal reinforcing member, and the first downward piece, the metal reinforcing member and the second resin frame form an indoor rail portion for guiding an inner sash. This is the upper frame of the window frame for the sash window.

[0008]

According to a first aspect of the present invention, there is provided an upper frame made of a composite sash material in which the inner surface of a metal frame on the indoor side is covered with a first resin frame. Since the rail portion is formed by reinforcing the downward piece of the first resin frame with the metal reinforcing member, the rigidity of the rail portion is large and the expected size is small, so that the expected size of the upper frame can be reduced. Since the exterior side surface of the metal reinforcing member is covered with the second resin frame and cannot be seen from inside the room, the inside appearance is good.

According to the second invention, the metal frame, the first resin frame, the horizontal piece of the metal reinforcing member, and the second resin frame and the horizontal piece are overlapped and connected by screws, so that the metal frame and the first resin frame are connected to each other by the screw. The resin frame, the metal reinforcing member, and the second resin frame are strong and can be easily connected.

According to the third aspect of the present invention, since the outdoor rail portion is formed by the downward piece of the metal frame and the second downward piece of the resin frame, the outdoor rail portion has a small expected size and a high rigidity. However, the first rail of the resin frame is reinforced with a metal reinforcing member on the indoor side rail, and the expected dimensions are small,
High rigidity. Because of this, the outdoor rail section,
Since the indoor side rail portion has a small expected size and high rigidity, the expected size of the upper frame can be reduced.

[0011] Further, since the inside side surface of the metal reinforcing member forming the indoor side rail portion is covered with the second resin frame, the metal reinforcing member is not seen from inside the room, and the inside appearance is good.
