BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and particularly to a refrigerator in which a leg assembly is installed on the bottom surface of a refrigerator body.

[0002]

2. Description of the Related Art As a conventional refrigerator, JP-A-2-27
As shown in Japanese Patent Publication No. 9973 (Prior Art 1),
In a refrigerator including a refrigerator body, a door that opens and closes an opening of a storage room, a leg body with a handle, a roller and an adjusting leg and a leg assembly installed on the bottom front part of the refrigerator body, the leg body with a handle is A roller portion, a handle portion, and an adjusting leg portion, and the roller portion has an upper surface portion and a roller portion having a roller inner supporting portion and a roller outer supporting portion extending downward from both sides of the upper surface portion,
The adjusting leg portion extends from the upper surface of the roller portion to the front side of the front surface of the refrigerator body, the handle portion has a handle portion extending laterally from the adjusting leg portion, and the roller is located in the roller portion and the roller inner supporting portion and In some cases, the adjusting legs are axially supported by the roller outer supporting portion, and the adjusting legs are located in front of the front surface of the refrigerator body and are attached to the adjusting legs from below.

A conventional refrigerator is disclosed in Japanese Patent Laid-Open No.
As disclosed in Japanese Patent Laid-Open No. 1-50641 (Prior Art 2), a refrigerator main body, a door that opens and closes an opening of a storage chamber, a leg body with a handle, a roller, and an adjusting leg are provided, and the bottom front of the refrigerator body In a refrigerator equipped with a leg assembly installed in the section,
The leg with handle has a roller portion, a handle portion and an adjusting leg portion,
The roller portion has an upper surface portion and a roller portion having a roller inner supporting portion and a roller outer supporting portion extending downward from both sides of the upper surface portion, and the adjusting leg portion extends from the upper surface portion of the roller portion to the front side of the front surface of the refrigerator body. The handle portion has a handle portion that extends laterally from a portion that extends rearward from the upper surface portion of the roller portion, and the roller is located inside the roller portion and is pivotally supported by the roller inner supporting portion and the roller outer supporting portion, and the adjusting leg. There is one that is located in front of the front of the refrigerator body and is attached to the adjusting leg from below.

[0004]

However, in the prior art 1, since the handle portion of the leg body with the handle extends laterally from the adjusting leg portion extending forward of the refrigerator main body, the floor surface and the handle portion are separated from each other. There was a problem that it was easy to pinch the toes of the installer in the gap. Further, since the handle portion is formed from the adjusting leg portion whose strength is not so great, there is a problem that it is difficult to secure sufficient strength when holding the handle portion. Furthermore, since the handle part extends almost horizontally from the adjusting leg,
In order to secure a sufficient gap between the handle portion and the lower surface of the door, the position of the lower surface of the door must be raised, which causes a problem that the volume of the storage chamber is reduced.

Further, in the prior art 1, since the adjusting leg portion is fixed to the bottom surface of the refrigerator main body only on one side of the handle portion,
There is a problem that it is difficult to sufficiently secure the strength of the handle portion, and the hand holding the handle portion may come off from one of the handle portions.

On the other hand, in the prior art 2, the handle portion of the leg body with the handle extends slightly downward from the horizontal portion or the flange portion extending rearward from the roller portion and extends laterally from the lower end portion thereof. For this reason, the leg with handle becomes large and expensive, and it becomes difficult to hold the leg with handle far behind the front end of the refrigerator body. There is a problem that it is difficult to secure sufficient strength when holding the handle because the handle is extended. Then, if the height of the falling part of the roller part is increased to increase the gap between the handle part and the bottom surface of the refrigerator body, the size of the leg body with the handle becomes even larger and expensive, and the standing part of the roller part increases. When the height of the lower portion is reduced, there is a problem that the gap between the handle portion and the bottom surface of the refrigerator main body becomes small and it becomes difficult to hold the handle portion.

Further, in the prior art 2, the left and right sides of the leg with handle are fixed by fasteners, but since the tip of the horizontal handle is fixed to the bottom surface of the refrigerator body, it is above the handle. In order to insert the finger into the refrigerator, the bottom of the refrigerator main body must be formed with a step outside the fixture. This causes a problem that the bottom shape of the refrigerator body becomes complicated.

Further, in the prior art 2, since the handle portion extends to the bottom plate side and the front end portion of the bottom plate cannot be pressed by foaming, the front end portion of the bottom plate is deformed by the foaming pressure of the urethane foam and the refrigerator main body is deformed. In addition to the decrease in strength, the gap between the handle and the bottom plate becomes narrower, which makes it difficult to insert the hand.

A first object of the present invention is to provide a refrigerator in which a leg with a handle can be manufactured inexpensively and easily transported while ensuring reliability in strength of the leg with a handle. .

A second object of the present invention is to provide a refrigerator which can be transported safely while ensuring the reliability of the strength of the legs with handles.

A third object of the present invention is to provide a refrigerator which can easily carry the refrigerator while ensuring the reliability of the strength of the refrigerator body.

The present invention is not limited to such an object, and objects and advantages other than the above will be apparent from the following description.
