JPH0960446A - Coped joint - Google Patents

Abstract

PROBLEM TO BE SOLVED: To produce a coped joint and facilitate the installation of it by forming a mounting part to be mounted on a window frame integrally with the right and left vertical frames of the coped joint which is installed projectedly from the window frame to the outer side, and fixing it to the window frame through the mounting part. SOLUTION: When a coped joint comprising an upper frame 12, a lower frame 13, and right and left vertical frames is produced, a mounting part 11a which is provided with a positioning projection 11c and a through hole (mounting hole) 11d on the right and left vertical frames is formed integrally with each other. Also the coped joint is fixed to a window frame with rivets through the mounting part 11a. By this, it is fixed rigidly without manufacturing mounting fittings separately. Thus the production cost and mounting cost for the coped joint can be reduced.

Utilizing this characteristic effectively, the surface lattice 10 of the present invention is formed in the following structure.

FIG. 2 is a sectional view taken along the line AA of FIG. 1 and shows a main part thereof. In FIG. 2, the rectangular vertical frames 11 having the left and right hollow cross-sections of the surface lattice 10 are formed by extrusion molding extruding in the longitudinal direction, and from the edge on the building side, the window frame is formed. Attached to 11
The a and 11a are formed so as to extend substantially flush with the outer end surfaces 11b and 11b of the vertical frame 11.

Further, the outer end surface of the mounting portion 11a is brought into contact with a window frame at the time of mounting, and a projection 11c for positioning is provided.
11c is provided.

As shown in the side view of FIG. 3, the mounting portion 11a is formed in a flat plate shape between the lower end of the upper frame 12 and the upper end of the lower frame 13. Also, the mounting portions 11a on both sides of this
