[0002]
[Prior art]
Usually, a metal door panel has a panel body formed by enclosing an inner frame and a reinforcing core member framed in a square shape by a C-shaped channel with a pair of surface plates. However, in recent years, a so-called frameless door has been developed in order to reduce the weight of the panel and reduce the cost. Has been. As this type of frameless door, one described in Japanese Patent Laid-Open No. 7-173972 (see FIG. 11) is known, but this is the side edge of the surface plates 2 and 3 cut into a predetermined shape. U-shaped bent portions 2a and 3a are formed in the portion, and the core material 4a and attachment liners 10 and 11 such as hinges and locks are bonded to the inner surface of the bent portion, and either one of the double-sided plates is attached. The frame member 1 is formed by bonding the core material 4b to the central portion and connecting these double-sided plates via connecting portions 200, 201, 300, and 301 formed at the respective end portions.
Since the frameless door constructed as described above does not include an inner frame inside the panel, the weight of the panel is reduced, the mounting work is improved, and the number of parts is reduced, thereby providing an inexpensive door panel. It has an excellent effect.
[0003]
[Problems to be solved by the invention]
However, in the conventional frameless door, the U-shaped bent ends are used to bond the core material 4a and the mounting liners 10 and 11 to the inner surfaces of the U-shaped bent portions 2a and 3a on both side edges of the panel. The core material 4a and the component mounting liner are inserted while the portion is expanded, and there is a risk that the mounting position is shifted as well as the operation is very difficult. Moreover, since both surface plates 2 and 3 are connected on the panel surface, a single connection line L is exposed on the panel surface, and there is a problem that the design of the panel is restricted.
