Description

[Detailed Description of the Invention] The present invention relates to a frame for a surrounding frame, a picture frame, etc. for architectural interiors.

Such a conventional rectangular frame is constructed by, for example, four longitudinal members connected to each other at right angles, and the ends of each longitudinal member are sharpened outward and cut at a 45 degree angle. They are connected by a fastening structure. In such a frame, cutting the ends of the longitudinal members at 45 degrees requires skill and is troublesome. In addition, if the longitudinal members constituting such a frame are irregularly shaped for decoration,
The cutting operation is difficult.

A typical prior art is shown in Japanese Utility Model Application No. 56-37660. In this prior art, a circumferential edge main body having a recessed line extending over the entire length in the longitudinal direction is disposed at a corner formed by a ceiling surface and a wall, and a space is created by the corner and the recessed line. The two ends of the back plate, which is approximately L-shaped and has a fitting recess on its surface, are fitted into the space from the end face of the main body near the protruding corner or the inner corner to form the protruding corner. Alternatively, it is a circumferential edge formed by fixing a back plate to the inside corner and fittingly attaching a decorative plate having a fitting convex portion on the back surface to the back plate while covering the surface of each end of the circumferential edge main body.

In such prior art, when the axis of the fitting protrusion is bent, there is a risk that the decorative plate having the fitting protrusion may shift from the desired position of the circumferential body, and this may cause the decorative plate to There is a problem in that the pattern between the rim and the main body of the rim becomes misaligned, resulting in an unsightly appearance.

Additionally, conventional edge bodies are generally rigid, for example made of wood, and therefore there is a problem in that the decorative laminate and the surface of the edge body cannot be brought into tight, elastic contact with each other.

It is an object of the present invention to provide an improved frame that does not create gaps at the corners of the frame and can provide a connected structure with improved aesthetics.
