[Problems to be solved by the device]

 However, in the above-described conventional structure, the fitting portion 7 of the handle 6 and the peripheral edge portion 6a of the handle 6 are configured to project outward from the outer surface of the outer plate 2, and therefore the handle 6 and the outer plate 2 are not provided. Cannot be made flush with each other, and there is no sense of unity between the handle 6 and the outer plate 2 and there is a large design restriction. Further, since the handle 6 projects from the outer plate 2, the projecting handle 6 portion is easily damaged, and further, the handle 6 is projected onto the molding jig of the door 1 used when foaming the foaming heat insulating material 4. It was necessary to provide a concave relief part to allow the part to escape.

Further, since the opening 5 of the outer plate 2 is formed by a simple hole, there is a drawback that the strength of the portion to which the handle 6 is attached is weak.

Therefore, an object of the present invention is to prevent the handle from protruding from the outer plate of the opening / closing body, which can widen the degree of freedom in design and eliminate the problem caused by the protrusion of the handle. Another object of the present invention is to provide a handle attachment device that can increase the strength of the portion to which the handle is attached.

[Means for Solving the Problems]

 The present invention provides a handle attaching device for attaching a handle to an opening formed in an outer plate of an opening / closing body, wherein a stepped flange that is recessed inward is provided at a peripheral portion of the opening of the outer plate. The handle is shaped to be accommodated in the opening, and has a configuration in which a peripheral portion has a fitting portion that fits into the flange.

[0008]

[Action]

 According to the above-mentioned means, the depth of the stepped flange provided on the peripheral edge of the opening of the outer plate and the thickness of the fitting portion of the handle fitted to this flange are appropriately set to fit the handle. It is possible that the outer surface of the joint portion is substantially flush with the outer surface of the outer plate or is recessed from the outer surface of the outer plate.

Further, the opening portion of the outer plate to which the handle is attached has rigidity increased by providing the stepped flange, and the strength can be increased as compared with a case where the opening portion is formed by a simple hole.

【Example】

 Hereinafter, an embodiment of the present invention will be described with reference to FIGS. First, in FIG. 3, on the front surface of the refrigerator 11, there are rotatably provided a door 12 for opening and closing the freezer compartment at the upper part and a door 13 for opening and closing the refrigerating room at the bottom part. These doors 12 and 13 form an opening / closing body, and a handle 14 is attached to a corner portion on the left side of the front surface of each of them.

Since the mounting structure of the handle 14 is the same for both the doors 12 and 13, it will be described with reference to FIGS. 1 and 2 on behalf of the door 12 side. The door 12 includes an outer plate 15 made of a steel plate, an inner plate 16 made of plastic, and a foamed heat insulating material 17 filled between the outer plate 15 and the inner plate 16.

In the outer plate 15, an opening 18 (see FIG. 2) is formed in a left corner portion where the handle 14 is attached. A bent portion 19 that is bent inward is formed over the entire circumference at the peripheral edge of the opening portion 18. Of the bent portion 19, the right portion of the front portion is An overhanging portion 20 that projects laterally is formed integrally so as to be substantially parallel to the outer surface of the outer plate 15. The portion where the bent portion 19 and the overhanging portion 20 are integrally formed is configured as a stepped flange 21 that is recessed inward. In addition, an engaging piece 22 that projects obliquely forward is integrally formed at the rear portion on the left side of the bent portion 19.

On the other hand, the handle 14 has a shape to be accommodated in the opening 18, and as shown in FIG. 1, a fitting portion 23 having a U-shaped cross section is provided at the peripheral portion on the front side. It is integrally formed, and an engaging convex portion 24 is integrally formed at the rear portion on the left side.

Thus, in the handle 14, the fitting portion 23 is fitted to the flange 21 of the outer plate 15 from the left side, and the engaging convex portion 24 is engaged with the engaging piece 22 of the outer plate 15. As a result, it can be attached to the opening 18 of the outer plate 15 in a retaining state. In the attached state of the handle 14, the handle 14 is accommodated in the opening 18, and the outer surface 23a of the fitting portion 23 is substantially flush with the outer surface 15a of the outer plate 15. At the same time, the outer surface 14 a of the peripheral portion of the handle 14 is substantially flush with the outer surface 15 a of the outer plate 15.

According to the present embodiment as described above, the depth of the stepped flange 21 provided on the peripheral portion of the opening 18 of the outer plate 15 and the fitting portion 23 of the handle 14 fitted to the flange 21. By setting the thickness of the outer wall portion 23b to be the same, the outer surface 23a of the fitting portion 23 of the handle 14 can be made substantially flush with the outer surface 15a of the outer plate 15. In this case, depending on how the depth of the flange 21 and the thickness of the outer wall portion 23b of the fitting portion 23 are set, the handle 14 can be recessed from the outer plate 15.

Therefore, unlike the conventional structure in which the fitting portion of the handle projects from the outer surface of the outer plate, the handle 14 and the outer plate 15 of the door 12 can have a sense of unity. Greater freedom. In addition, since the handle 14 can be prevented from protruding from the outer plate 15, the handle 14 portion can be less likely to be scratched than in the conventional case, and the door 12 used for foam filling of the foam insulation 17 can be formed. It is possible to eliminate the need for providing a jig (not shown) with a concave relief portion for escaping the protruding portion of the handle, and it is possible to eliminate the problem caused by the protrusion of the handle.

Further, the opening 18 portion of the outer plate 15 to which the handle 14 is attached increases rigidity by providing the bent portion 19 and the flange 21, and is stronger than the opening portion formed by a simple hole. There is also an advantage that you can strengthen.

The present invention is not limited to the refrigerator door, and can be applied to, for example, a door of a cabinet or a handle portion of a drawer.
