A roller pin insertion hole 10d having a diameter larger than the roller pin 12 is formed correspondingly in the roller support parts 1 ob and 10'c, and a roller pin insertion hole 10d made of metal is made to withstand the weight of one refrigerator body. roller, pin 12
was inserted while supporting the roller 13, and a portion 12a was formed on one side to prevent crushing by a mechanical tool or the like.

Problem to be Solved by the Invention However, with this configuration, the refrigerator is not fixed in place after it is installed, so if there is no wall behind the refrigerator, the refrigerator may fall over or be violently damaged during an earthquake. Refrigerators are difficult to move, especially those with shallow depth and high height, which have the problem of being easy to topple over. In order to solve the above problem, some refrigerators are installed with the board 1o and rollers 13 extending rearward from the back plate 2c of the outer box 2, but in this case, the refrigerator is installed in a place where there is a wall behind the refrigerator. When installed, a large dead space will be formed between the back plate 2c and the wall, increasing the installation area9.
This results in a reduction in kitchen space. In addition, there have been other problems such as increased costs due to the larger packaging used for shipping the refrigerator.

The present invention solves these conventional problems, and prevents the refrigerator from tipping over or moving even when installed in a place without a wall behind it, and also prevents the refrigerator from falling over or moving when installed in a place with a wall behind it. Also, there is no dead space between the back plate and the wall, and the aim is to downsize the packaging and reduce costs.

Means for Solving the Problems In view of the above problems, the present invention provides a refrigerator that is rotatably supported by support pins on the lower surface of the board and installed so as to protrude from the back surface of the refrigerator when rotated, and a floor installation bolt is provided at the tip of the protrusion, and It is equipped with a caster body with rollers provided near the support pin.

With the above-described configuration, when the present invention is installed in a place where there is no wall behind the refrigerator, the caster body supported by the support pin is rotated to protrude from the back of the refrigerator, and the caster body provided at the tip of the protrusion part can be installed on the floor. It can be installed on the floor by adjusting the height of the bolt. Furthermore, when installing the refrigerator in a place with a wall behind it, the caster body protruding from the back of the refrigerator can be rotated and housed within the bottom surface of the board.

EXAMPLE An example of the present invention will be described below with reference to the accompanying drawings. It should be noted that for numbers in the drawings that match those of the conventional example, the numbers of the conventional example are used.

In FIGS. 1 to 5, reference numeral 1 denotes a refrigerator body made of a heat insulating material 4 filled between an outer box 2 and an inner box 3. A machine room 6 is formed in the lower part of the main body 1 by the bottom plate 2a of the outer box 2. A compressor 8 is attached to a board 14 made of iron plate via a cushioning material 9. This board 14 is fixed to the lower 7 langes 2b of the outer box 2 with screws 11, and support pin insertion holes 14a are provided on both sides to support the caster body 16 with support pins 16 in a freely regenerative manner. Caster body support parts 14b, 14 are provided near the insertion hole 14a.
C is cut and raised downward in an abbreviated shape. The caster body 15 includes a frame 17 and roller pins 12 . roller 1

In addition, since the floor installation bolts 18 are installed to protrude from the back plate 2c of the outer box 2, the refrigerator will not fall over due to an earthquake or the like even if it is installed in a place where there is no wall behind the refrigerator. When installing the refrigerator in a place where there is a wall behind it and when shipping the refrigerator, the caster body 16 is attached to the roller support portion 17d of the frame 17 on the caster body support portion 14b as shown in the figure (solid lines in FIGS. 1 and 2). It is fixed by bringing it into contact with the substrate 1.
4 Since it is stored in the lower surface, there is no gap between the back plate 2C of the refrigerator and the wall, and the installation area can be reduced and the space between kitchen windows can be increased.

Furthermore, the packaging for shipping the refrigerator can be made smaller, reducing costs.

Effects of the Invention As is clear from the above description, the present invention has a caster body that is rotatably supported by support pins on the bottom surface of a board and installed so as to protrude from the back of the refrigerator when rotating, and an upper side that comes into contact with the bottom surface of the board. The caster body can be rotated even if the refrigerator is installed in a place where there is no wall behind the refrigerator because it consists of a frame with an integrated support part that supports the rollers and a floor installation bolt provided at the end of the frame. The floor installation bolts are installed to protrude behind the back plate, preventing the refrigerator from falling over due to earthquakes, etc., and since the rollers also rotate (90'), the rollers also stop the refrigerator from moving backwards. be able to. In addition, when installing the refrigerator in a place with a wall behind it or when shipping the refrigerator, the caster body can be rotated with one touch and stored within the bottom surface of the circuit board, thereby reducing the gap between the back panel of the refrigerator and the wall. The installation area can be reduced and the space between kitchen windows can be increased without causing problems. In addition, the packaging for shipping the refrigerator can be made smaller and costs can be reduced, so the implementation effects and practical utility are extremely large.
