Abstract

A handle structure is provided with handles and finger insertion recesses disposed on each of first and second doors. Each handle is provided with a finger-hook plate piece that extends vertically while protruding from the vicinity of one end faces on an outer surface, where first and second doors are bendably joined, toward other end faces. The finger insertion recesses are formed on the outer surfaces of the first and second doors in such a manner as to face the finger-hook plate pieces, and are formed in dimensions that enable fingers to be hooked on inner surfaces of the handles. The handles and the finger insertion recesses are formed in a bilaterally symmetrical shape with the end faces, which face each other, of the doors in the center.

First claim

What is claimed is:

1. A structure including a bi-fold door and handles, in which the bi-fold door comprises two rectangular-plate-shaped doors, each of the two rectangular-plate-shaped doors having first and second end faces at ends in a direction of a width of the bi-fold door, the two rectangular-plate-shaped doors being bendably joined together at the first end faces, each of the two rectangular-plate-shaped doors having an outer surface, and the two rectangular-plate-shaped doors being configured to fold in a V-shape at the first end faces toward an outside of the outer surfaces so as to open an opening part, on each of the two rectangular-plate-shaped-doors:
the handle and a finger insertion recess are provided together at a position on the outer surface near the first end face, the handle and the finger insertion recess being formed integrally with the rectangular-plate-shaped door;
the handle is provided with a finger-hook plate piece in which the handle extends in longitudinal direction of the rectangular-plate-shaped door on the outer surface at the first end faces;
the finger insertion recess is provided on the outer surface of the rectangular-plate-shaped door so as to face the finger-hook plate pieces;
an interval between an inner surface of the finger-hook plate piece which faces the finger insertion recess and a bottom surface of the finger insertion recess being formed with dimensions which enable fingers to be hooked on the inner surface of the finger-hook plate pieces;
as viewed from a front of the rectangular-plate-shaped door, the bottom surface of the finger insertion recess is formed up to a position outside of a contour of the finger-hook plate piece, except at positions at upper and lower ends of the finger-hook plate piece, and is connected to the outer surface of the rectangular-plate-shaped door; and
the bottom surface of the finger insertion includes an inclined surface area, wherein a depth of the finger insertion recess in a direction of the width of the rectangular-plate-shaped door gradually increases toward the first end face;
wherein the handle and the finger insertion recess provided in the one of the rectangular-plate-shaped doors and the handle and the finger insertion recess provided in the other one of the rectangular-plate-shaped doors are formed in a bilaterally symmetrical shape with the respective first and faces as a center.

2. The structure according to claim 1 , wherein
in each of the rectangular-plate-shaped doors, the finger-hook plate piece includes the upper and lower ends and an intermediate portion between the upper lower ends, the intermediate portion being formed by an inclined plate portion inclining with respect to the outer surface, the finger-hook plate piece extends in a longitudinal direction of the rectangular-plate-shaped with a fixed width, and inclines away from the outer surface as the inclined plate portion extends away from the first end face, and the upper and lower ends of the finger-hook plate piece are formed by connecting plate portions which connects the outer surface with the inclined plate portion.

3. The structure according to claim 1 , wherein
in each of the rectangular-plate-shaped doors, the finger-hook plate piece includes the upper and lower ends and an intermediate portion between the upper and lower ends, the intermediate portion being formed by an erected plate portion which is erected along the first end face in the thickness direction of the rectangular-plate-shaped door and a parallel plate portion which is bent from a leading end of the erected plate portion, so as to be parallel with the outer surface at a position away from the outer surface and extends in a longitudinal direction of the rectangular-plate-shaped door with a fixed width, and the upper and lower ends of the finger-hook plate piece are formed by connecting plate portions which connect the outer surface with the erected plate portion and the parallel plate portion.
