Description

[Detailed description of the invention] This invention has a structure in which a pair of adjacent frames of glass doors, shoji doors, etc. are connected at 90 degrees, and more specifically, a pair of frames integrally equipped with a frame are connected at 90 degrees. It is related to the device.

BACKGROUND ART Conventionally, in glass doors, shoji doors, etc. made of frame materials that generally have a decorative surface around the glass, the frame and the stile that constitutes the shoji door, etc. have been separate bodies.

As a result, the frame material and the frame material have a double structure, which has disadvantages such as high material costs and the accumulation of dust and dirt on the connected parts, making them unsightly.

Therefore, in order to eliminate such drawbacks, a structure in which the picture frame and the frame were integrally formed was proposed, but this method was based on a connecting structure of the picture frame, which had not been generally adopted in the past, that is, as shown in Figure 1. Because it is a connected structure in which only the opposing surfaces c and c are cut at 45 degrees and the cut end surfaces c and c are butted against each other, the notched end surfaces c/ and c/ of the frame a are difficult to match, resulting in a step S and a gap. S1 will occur.

For this reason, the notch end surface c that has not been surface treated (coloring, etc.)
/, c/ are exposed to the outside and can be seen, resulting in an unsightly appearance.

This problem becomes more noticeable in colored sashes whose surfaces are colored to improve their appearance.

Furthermore, rainwater or the like may enter the stile through the gap S, leading to early corrosion.

In addition, the opposing end surfaces of the pair of picture frames a and a are each 45
Processing is troublesome as it requires repeated cutting.

The present invention was created in view of the above circumstances, and its purpose is to connect a pair of frame frames so that they can be connected correctly at 90 degrees without creating a step or gap between the joints of the frame. The purpose is to provide a structural device.
