で衝撃は小さい。However, in the door support roller of the present invention, the roller support base 17b is rotatable downward around the mounting hole 21, and the nupling 1
8, it is biased downward. Therefore, when the roller 15-1 is about to move away from the inclined part 25 of the roller riding surface 19, the second roller 15-2 is on the inclined part 25, and the nupling 18 is urged downward and the door is closed. 20
The roller 15-2 supports part of the weight and moves smoothly to absorb the impact. Similarly, roller 15
-2 tries to move away from the inclined part 25,
The third roller 15-3 moves to the inclined portion 25 and absorbs the impact caused by the right-hand descent (inclination) K of R2. When the roller 15-3 leaves the inclined part 25, the impact is small because the roller assembly 14b provided on the left side of the door 2 still remains on the roller riding surface 19 or the inclined part 25. When the door 2 is further opened, the roller 15-4 attached to the roller assembly 141) moves to the inclined portion 25.
As the door 2 descends, the weight of the door 2 is applied to the roller 15-5, so the nupling 18 is compressed and the roller support 1
7t) is about to tilt toward the upper left with respect to the door 2, but since a cut portion 26 extending downward to the left is provided at the upper left side of the mounting hole 21 of the roller support 17b, this cut portion 26 The roller support stand 17b can be tilted upward to the left until it touches the bottom surface of the door 2. Therefore, when the roller 15-4 leaves the inclined part 25, the roller 15-5 or the inclined part 25
In addition, the roller 15-6 is positioned on the roller landing surface 19 to reduce the impact when the roller 15-4 separates from the refrigerator main body 1. When the roller 15-5 leaves the inclined part 25, the roller 15-6 is positioned on the inclined part 25 to reduce the impact caused by the separation of the roller 15-5. However, when the roller 15-6 leaves the inclined portion 25, there is no roller to reduce the impact, but from the roller 15-6 to the hinge pin 3.
The distance to b is short and the slope of door 2 is almost finished, so the impact is small.

る。<Effects of the Invention> As is clear from the above explanation, the door support roller of the present invention for a left and right double-hung door is attached to the bottom surface of the door substantially parallel to the door, and the load on the door is reduced when the door is opened and closed. One end of the roller support base supporting the section is rotatably attached so that the other end can move up and down, and the other end is configured to press the roller support base downward by inserting a spring. The elasticity of the spring and the inclination of the roller assembly can reduce the impact when the roller approaches and separates from the surface on which the roller rides when the door is opened and closed.
