Title: Connected structure of jamb and lower cross rail of projecting sash
Inventor: ISHIGURO YOSHINORI
IPC: E06B1/18
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To enhance strength of a connected structure by butting the end face of the sash mounting part of a lower cross rail against the inner surface of the sash mounting part of a jamb, butting the lower end face of the cover part of the jamb against the upper surface of the cover part of the lower cross rail, and connecting them together using screws from both vertical and horizontal directions. SOLUTION: A lower cross rail 1 is obtainable by cutting a sash mounting part 9 and a cover part 2 simultaneously along a straight line, so notching of the cover part 2 that was performed in conventional cases is not necessary. Next, the lower end face 12a of the inward piece 12 of a jamb 4 and the lower end face 5c of the cover part 5 are made to abut to the upper surface 2a of the cover part 2 and are connected thereto by screws 16, 19. In this case, the tightening force of the screw 16 is exerted in the longitudinal direction of the lower cross rail 1, and that of the screw 19 in the longitudinal direction of the jamb 4, resulting in increased connecting strength.  When desired a watertight member made of a rubber block or the like is mounted on that end of the cover part 2 which projects sideways from a cover part 5, to keep watertight the portion of contact between each cover part 2, 5 and the inward piece 12. Thus strength, watertightness, and machinability can be enhanced.
