Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a lower frame of an upper window frame and an upper frame of the lower window frame which form a step window.

[0002]

2. Description of the Related Art As a stepped window, it is known that the lower frame of the upper window frame and the upper frame of the lower window frame are connected to each other to connect the upper window frame and the lower window frame. As a structure to be connected, for example, the structure shown in Japanese Utility Model Laid-Open No. 2-128783 is known.

That is, the lower frame and the upper frame are butted against each other, and a connecting material is provided across the lower frame inner side portion and the upper frame inner side portion, and the connecting material is connected to the upper frame inner side portion and the lower frame inner side portion. The lower frame and the upper frame are connected by fixing with screws.

As a composite window using a semi-external sash, for example, as shown in Japanese Utility Model Laid-Open No. 63-138390, the frame attachment piece of the vertical frame is cut and removed halfway,
It is known that the remaining portions after cutting and removing are connected by a cubic material to connect the vertical frames of the semi-external sash.

[0005]

In the former connection structure, since the lower frame lower part and the upper frame upper part are in contact with each other and vertically positioned, the vertical frame of the upper window frame and the vertical frame of the lower window frame are connected. Since the upper part may interfere, it can not be connected correctly, and the connecting work becomes difficult.

In other words, since the upper frame and the lower frame are butted against and connected to the vertical frame, the upper part of the vertical frame may project above the upper part of the upper frame, and the lower part of the vertical frame may project below the lower part of the lower frame. In this case, when the lower frame lower part and the upper frame upper part are brought into contact with each other, the upper and lower vertical frames interfere with each other, so that they cannot be correctly connected and the connecting work becomes difficult.

Further, in the case of the above-mentioned connecting structure of the semi-external sash, burrs or the like are generated in the cut-and-removed portion of the body mounting piece, and the burrs or the like make the connection by the upright material difficult and troublesome. In other words, if there is a burr in the remaining portion, it cannot be properly connected to the cubic material, and since the burr is removed and then connected to the cubic material, the connection by the cubic material is difficult and troublesome.

Therefore, an object of the present invention is to provide an upper frame and lower frame connecting structure for a step window which can solve the above-mentioned problems.

[0009]

[Means for Solving the Problems] An upper surface of an upper frame is formed to have a step having a higher outdoor side and a lower indoor side, and an engaging concave portion and a connecting member supporting portion which are open upward are formed on the indoor upper surface of the upper frame. , The lower surface of the lower frame has a step with a lower outdoor side and a higher indoor side, and the locked piece is integrally provided at the step portion of the lower frame toward the indoor side, and the connecting material support part is provided on the lower surface on the indoor side. Forming a connecting member, an engaging convex portion engaging with the engaging concave portion and a lower supporting portion in contact with the connecting material supporting portion at a lower portion thereof, and an upper portion engaging with the locked piece. An engaging piece and an upper support portion that is in contact with the connecting material support portion are provided, and the engaging protrusion and the upper engaging piece engage with the engaging recess and the engaged piece, respectively,
The upper and lower frames are temporarily fixed to each other by connecting the upper and lower supporting parts to each connecting material supporting part with a gap between the upper surface and the lower surface of the outdoor side of the upper frame and the lower frame of the outdoor side, and fixing the connecting material and the lower frame with screws. The upper and lower frame connection structure of the stepped window.

[0010]

[Operation] The upper frame and the connecting material are supported by the engaging portions of the engaging concave portion and the engaging convex portion, and the connecting material supporting portion of the upper frame and the lower supporting portion of the connecting material are in contact with each other, so that the connecting material is raised.
