Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal-resin composite in which a metal outdoor member made of aluminum or the like used for sliding doors and sliding doors is combined with a resin indoor member such as vinyl chloride or acrylic resin. A frame and a glass shoji using the frame.

[0002]

2. Description of the Related Art As a frame for forming a glass shoji, an elongated member made of aluminum and having a cross section having a recess for mounting glass is known. This frame is connected in a square shape to form a frame assembly, and glass is attached to the concave portion of each frame to form a glass shoji. Since the above-mentioned frame is made of aluminum, heat is easily transferred to the inside and outside of the room.The glass shoji using this frame has a large difference in temperature between the indoor and outdoor areas such as in cold regions. Condensation occurs on the indoor surface.

As a frame that solves this problem, there has been proposed a metal-resin composite frame which is a combination of a metal outdoor member made of a metal such as aluminum and having a recess for mounting glass and a resin indoor member. Since the interior surface of this metal-resin composite frame is made of resin, the glass shoji using this frame is unlikely to cause dew condensation on the interior surface of the frame in cold regions.

[0004]

In the above-mentioned metal-resin composite frame, since the indoor surface of the metal outdoor side member is in contact with the outdoor surface of the resin indoor side member, the metal outdoor side member and the resin indoor side The contact area of the member is a large value according to the cross-sectional shape and length. For this reason, a certain amount of heat is transferred to the metal outdoor side member and the resin indoor side member, and the heat insulation performance is poor,
Condensation may occur on the indoor surface of the frame when the temperature difference between the indoor and outdoor areas is large, such as in cold regions.

In order to solve this problem, it is conceivable that the resin inner member is hollow to improve the heat insulating property. However, the shoji using the metal-resin composite frame has a large opening size of the recess for mounting glass, because the pair of glasses is attached to improve heat insulation. For this reason, if the resin inner member is hollow, the expected size of the frame becomes large and the estimated size of the window frame also becomes large. Therefore, it is not preferable to make the resin indoor side member hollow, and it is not possible to completely prevent dew condensation on the indoor surface of the frame when there is a large temperature difference between the indoor and outdoor areas such as in cold regions.

Therefore, an object of the present invention is to provide a metal-resin composite frame and a glass shoji which can solve the above problems.

It is a long member having a cross-sectional shape having a predetermined width, height and length, which has a concave portion 15 for use. The indoor side plate 11 has a hook-like shape on the indoor side portion forming the recess 15 with the horizontal portion 16 and the vertical portion 17, and the opening size H ₁ of the recess 15 is larger than the estimated size H _{2 of the} main body 14.

One end surface 11a of the indoor side plate 11 (recessed portion 1
5, the one end surface 12a of the outdoor side plate 12 projects to the other side in the height direction, and the part of the indoor side plate 11 projecting from the connecting plate 13 forms a locking piece 18 continuous in the longitudinal direction. . A recessed groove-shaped engaging portion 19 is integrally formed continuously in the longitudinal direction near the recess 15 of the portion of the indoor side plate 11 forming the main body 14.

A plurality of notches 20 are formed at longitudinally intermediate portions of the lateral portion 16 and the longitudinal portion 17 of the indoor side plate 11 at intervals in the longitudinal direction. The length, spacing, and number of the cutouts 20 are arbitrary, and one cutout may be formed over the entire length of the intermediate portion in the longitudinal direction as shown in FIG. Further, as shown in FIG. 5B, the portions near both ends in the longitudinal direction may be cut out. That is, the notch may be formed by leaving the remaining portion 21 that supports the glass. The vertical portion 17
The notch 20 may be formed only on the bottom.

The resin interior side member 30 has one side portion 31 in the height direction (a portion facing the portion forming the concave portion 14 of the metal side chamber outer member 10) and the other side portion 32 in the height direction (metal chamber). The portion of the outer member 10 facing the main body 14) has substantially the same height as the metal chamber outer member 10. One side part 3 in the height direction
1 has a thin plate-like shape and has locking pieces 33 on its edges, which are in contact with the inner surface of the vertical portion 17 of the metal outdoor member 10 as shown in FIG. Lock on the edge.

The other side portion 32 in the height direction is the first hollow portion 3
4 and the second hollow portion 35, the prospective dimension of the first hollow portion 34 is large, the indoor side surface is flush with the indoor side surface of the one side portion 31 in the height direction, and the indoor side surface is in the height direction. It projects outside the one side portion 31. A locking piece 36 is integrally provided on one side of the outdoor side surface. The first hollow portion 34 is in contact with the lateral portion 16 of the metal outdoor side member 10 and the inner surface of the main body 14, and the locking piece 36 is locked with the locking portion 19.

The second hollow portion 35 projects more outward than the first hollow portion 34, and a groove-like locking portion 37 is formed continuously on one side in the longitudinal direction. In the second hollow portion 35, the locking portion 37 is locked to the locking piece 18 of the metallic outdoor side member 10, and the second hollow portion 35 is the outdoor side plate 1 of the metallic outdoor side member 10.
An outer portion that is narrower than the portion that forms the main body 14 of 2 and faces the other side in the height direction is formed.

Because of this, the metal outdoor member 1
The vertical portion 17 of the indoor side plate 11 of No. 0 is covered with the height direction one side portion 31 of the resin indoor side member 30, and the main body 14 having the hollow portion of the indoor side plate 11 of the metallic outdoor side member 10.

The other side portion 3 in the height direction of the resin indoor side member 30
The end portion 2 (the second hollow portion 35) of the second portion is closer to the outdoor side, and forms a narrow outer side portion in opposition to the height direction / other side side portion of the outdoor side vertical plate 12 of the frame body 10. It is possible to increase the opening size of the recess 15 in the inner part and reduce the expected size of the outer part.

The portion near the end is hollow and has high strength, and the locking portion 37 has a locking piece 18 of the metal outdoor side member 10.
Since it is locked to, the mounting strength is great. As a result, the strength of the outer portion can be sufficiently maintained, and the heat insulating property of that portion is excellent.

The upper frame 1 and the door stop frame 4 of the internal shoji B have substantially the same cross-sectional shape as the lower frame 2 as shown in FIGS.
As shown in FIG. 3, the summing frame 3 is made of a resin indoor member 30.
The one side portion 31 has a hollow shape.

The lower frame 2 and the door stop frame 4 are connected as shown in FIG. 6 or 7. The metal frame outer side member 10 of the lower frame 2 is cut out at both ends in the longitudinal direction of the portion forming the recess 15 of the outdoor side plate 11. The remaining outdoor side plate 11, indoor side plate 12, and resin indoor side member 30 are pressed against the recess 1 of the frame 4.
