Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door of a refrigerator or the like having a handle for use in taking in and out storage items such as food.

2. Description of the Related Art A conventional example will be described below with reference to FIGS. 1 is a refrigerator main body, 2 is a freezer compartment door, and 3 is a refrigerator compartment door. The refrigerator compartment door 3 is a door plate 4 coated on a steel plate.
And a door frame 5 extruded with a hard PVC resin provided so as to cover the outer peripheral end portion of the door plate 4 and bent into a frame shape, are integrally fixed with a foamed heat insulating material 6. . A door back plate 8 integrally formed with a food storage shelf and a gasket 9 for sealing the outer periphery of the door are attached to the inside of the refrigerator compartment door body 7. On the other hand, a handle plate 10 is attached to the outer surface side of the refrigerator compartment door body 7, and a decorative plate 11 is attached on the handle plate 10.
Are screwed into mounting holes 14 provided in the door plate 4 by screws 13. Further, a handle decorative plate 15 is fitted and locked to the handle main body 12 so as to hide the screw 13. The door plate 4 is a flat plate, on which the handle body 12 and the like are protruded and mounted as described above. When the stored food is taken in and out, the handle body 12 is held and the refrigerator compartment door 3 is held. It opens and closes. The door frame 5 is formed by extruding a rigid PVC resin and bending it into a frame shape.
They are butt-connected at 16. The longitudinal edges 16 are formed by cutting the end of the right side 17 and the end of the lower side 18 of the door frame 5 into a 45 ° inclined surface and abutting each other, and forming these two sides at a right angle. It is provided at the lower corner of the rotation center XX of the time. The other three corners 19 are bent portions and have small curved surfaces. The above configuration is the same for the freezer compartment door 2.

However, in the above configuration, the handle main body 12 is screwed.
At 13, it is attached to the door plate 4, and this screw 13 must be hidden in order to keep the appearance aesthetically beautiful. Since the handle body 12 is attached to the flat door plate 4 so as to protrude, the body may hit the protruded handle body 12 during actual use, or a kitchen utensil during transportation may hit the handle body 12. This was one of the factors that reduced or hindered the efficiency of housework tasks such as cooking. When the door is fully opened,
On a cupboard etc. installed adjacent to the freezer body 1,
In some cases, the protruding handle body 12 collided and damaged.

Further, the vertical edge 16 of the door frame 5 may have a slight deviation between the terminal end of the right side 17 and the terminal end of the lower side 18, and the front end thereof has a sharp shape cut at 45 °. Inadvertently touching 16, for example, my fingers and toes were cut off, so I couldn't help avoiding very dangerous factors. Conventionally, there have been problems in assembly and quality as described above.

The present invention solves the problems of the conventional example described above, simplifies the handle structure of the refrigerator door, minimizes the protrusion from the door surface, eliminates the sharp shape of the vertical door frame, and is easy to use. It provides products with enhanced safety.

Means for Solving the Problems To solve the above problems, the present invention provides a door plate and a door back plate,
A door frame that is bent and attached so as to surround the outer peripheries of these two plates, a foam insulating material filled in a space formed by these members, and a notch provided in a corner of the door plate, It has both ends of the door frame which are arranged facing away from the notch, and a handle provided so as to cover the notch of the door plate, without projecting to the front side integrally with the handle. It has a formed finger hook, an engagement hole provided at an end of the door frame, and an engagement projection provided on the handle at a position facing the engagement hole.

Operation The present invention can simplify the structure of the handle portion, minimize the protrusion from the door surface, and eliminate the sharp edge of the vertical length of the door frame by the above configuration.

Embodiments Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1, 2, and 3. FIG.

Reference numeral 3 denotes a refrigerator compartment door, which is a door frame 5 that covers an outer peripheral end of the door plate 4.
Are integrally fixed by the foam heat insulating material 6. Further, the door back plate 8 and the gasket 9 are attached to the refrigerator compartment door body 7, but the above is the same as the configuration of the conventional example shown in FIGS. The detailed description is omitted.

A notch 20 is provided at the upper left corner of the door plate 4, and the end 22 of the upper side 21 of the door frame 5 is matched with the position of the notch 20.
The left end 23 of the left side 23 is formed to have a separation portion 25 having substantially the same size as the cutout portion 20. The handle 26 is provided so as to cover the cutout portion 20 of the door plate 4 and the separation portion 25 of the door frame 5, and has an end surface 27 of the cutout portion 20 of the door plate 4 and an end portion of the upper side 21 of the door frame 5. The end 24 of the left side 23 is inserted into the inside of the handle 26 so that it cannot be seen from the outside. Engagement holes 28 are provided in the vicinity of the ends 22 and 24 of the door frame 5, respectively. Engagement projections 29 are provided on the handle 26 at corresponding positions, and are engaged with each other. The upper side 21 and the left side 23 of 5 are integrally fixed. The handle 26 is integrally formed with a finger hook portion 30, but the thickness is approximately the thickness A of the door frame 5 plus the thickness required for general molding.

In the above-described configuration, the handle 26 integrally forms the engagement protrusion 29 and the finger hook portion 30 and is engaged with the engagement hole 28 of the door frame 5 to be combined. As a result, since it is integrally fixed together with the door frame 4, it can have sufficient strength.
When the refrigerator compartment door 3 is opened and closed, it is possible to sufficiently put a finger on the finger hook 30. Further, since it is provided on the upper left side opposite to the rotation center XX at the time of opening and closing, it is opened and closed with a minimum force. Actions can be taken.

Since the handle 26 has a size slightly larger than the thickness A of the door frame 5, it is practically a substantially flat state. Since there are no protrusions, the body and the body can be used even in housework in the kitchen.
There are no tools hit, and even when the door is fully open, there is no collision or damage to adjacent furniture. The door frame 5 has a separation portion 25, and the other three corner portions 19 are all bent portions and have small curved surfaces, so that they do not have sharp end surfaces. Also, since the ends 22, 24 are not separated but are separated from each other, 4
There is no need to cut on a 5 ゜ slope, and a 90 ゜ cut is sufficient, and it does not become sharp. Moreover, the end is not exposed because it is covered by the handle 26. Therefore, even if any part is touched, it is smooth and there is no danger of cutting a finger or the like.

Effect of the Invention As described above, the present invention provides a handle having a finger hook portion integrally with a door frame separation portion substantially the same as the door plate cutout portion in a practically flat state having a thickness slightly larger than the door frame thickness. Therefore, the number of handle parts can be reduced, the structure can be made very simple, the protrusion from the door surface can be made small, the efficiency of housework such as cooking in the kitchen can be improved, and there is no damage to adjacent furniture ,
An object of the present invention is to provide a door for a refrigerator or the like which has high safety, is easy to use, and can be easily assembled and manufactured.
