Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a caster body supporting device used in a refrigerator-freezer or the like.

2. Description of the Related Art A conventional example will be described with reference to FIGS. Reference numeral 1 denotes a refrigerator main body including an outer box 2, an inner box 3 and a heat insulating material 4 filled between the boxes 2 and 3. The bottom plate of the outer box 2 is at the bottom of the main body 1.
The machine room 5 is composed of 2a. Reference numeral 8 denotes a compressor, which is attached to an iron plate substrate 10 via a cushioning material 9.
The substrate 10 is fixed to the lower flange 2b of the outer box 2 with screws 11, and roller supporting portions 10b and 10c are formed on both sides by cutting and raising. These roller support parts 10b, 10c
Correspondingly, a roller pin insertion hole 10d larger than the diameter of the roller pin 12 is opened, and the roller pin insertion hole 10d is inserted by the roller pin 12 made of metal so as to support the weight of the refrigerator main body 1 while supporting the roller 13. Then, the one side is formed with the crush-out prevention portion 12a by a mechanical tool or the like.

The problem to be solved by the invention However, in such a configuration, since the refrigerator is not fixed to the place after the refrigerator is installed, if there is no wall behind the refrigerator, the refrigerator may collapse or move violently in the event of an earthquake or the like. However, there is a problem in that the refrigerator is shallow and the height is high, and the refrigerator easily falls. In addition, in order to solve the above problems, the substrate 10 and the roller 13 are attached to the outer box 2
Some of them are mounted so as to extend rearward from the rear plate 2c of this, but in this case, when installed in a place where there is a wall behind the refrigerator, a considerably large dead space is created between the rear plate 2c and the wall. This will increase the installation area and decrease the kitchen space. In addition, there is a problem in that costs increase due to an increase in the size of the package shipped in the refrigerator.

The present invention solves such a conventional problem. Even when installed in a place without a wall behind, the refrigerator does not fall or move, and it is installed in a place with a wall behind. However, there is no dead space between the back plate and the wall, and the purpose is to reduce the size and cost of the packaging.

Means for Solving the Problems In view of the above problems, the present invention is rotatably supported on a lower surface of a substrate by a support pin and is installed so as to project from a refrigerator at the time of rotation. A frame provided with a roller is attached near the pin.

Operation The present invention has the above-described configuration, and when installed in a place where there is no wall behind it, the frame supported by the support pins is rotated to project from the back of the refrigerator, and the floor installation bolt provided at the tip of the projecting portion. It can be installed on the floor by adjusting the height of. Also, when the wall is installed behind, the caster body protruding from the back of the refrigerator can be rotated to be housed in the lower surface of the substrate.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings. For the numbers in the figure that match those of the conventional example, the numbers of the conventional example are used.

In FIG. 1 to FIG. 5, reference numeral 1 is a refrigerator body composed of a heat insulating material 4 filled between an outer box 2 and an inner box 3. At the lower part of the main body 1, a machine room 5 is constituted by the bottom plate 2a of the outer box 2. Reference numeral 8 denotes a compressor, which is attached to a base plate 14 made of an iron plate via a cushioning material 9. This board 14 is fixed to the lower flange 2b of the outer box 2 with screws 11, and support pin insertion holes 14a for rotatably supporting the caster body 15 by the support pins 16 are provided on both sides. Caster body supporting portions 14b and 14c are cut and raised downward in the vicinity of 14a in a substantially L shape. The caster body 15 is composed of a frame 17, a roller pin 12, a roller 13, and a floor surface mounting bolt 18. The frame 17 is an upper side 17 that abuts the lower surface of the substrate 14.
a support hole 17b for supporting the support pin 16 on a, and this support hole 17b
Screw holes 17c for fixing floor installation bolts 18 and roller supporting portions 17d, 17e for supporting the roller 13 are provided at the tip of the upper side 17a with a greater distance. Roller pin insertion holes 17f larger than the diameter of the roller pin 12 are formed in the roller support portions 17d and 17e, and the roller pin 12 is inserted to support the roller 13 in the roller pin insertion hole 17f, and one of them is pushed by a machine tool or the like. Collapse prevention section 12a
Are formed. Floor installation bolt 18 is a bolt on the upper part
18a, and a bolt 18a made of synthetic resin or the like at the lower part is constituted by a grip portion 18b formed in a circular shape by insert molding, and the tip of the bolt 18a is inserted into a screw hole 17c provided in the frame 17 and rotationally supported. With this, the handle portion 18b can be moved up and down.

In the above structure, the caster body 15 is provided as shown in the drawing (first
(Figure arrow) Rotate the support pin 16 as a fulcrum until the end surface of the frame 17 of the caster body 15 comes into contact with the caster body support portion 14c (two-dot chain line in FIG. 1). By rotating and adjusting the height until it is installed on the floor surface, it is surely fixed on the floor surface, and by rotating the caster body 15, the roller 13 integrally provided on the caster body 15 is also the same. Since it rotates (90 °), the backward movement of the refrigerator can also be stopped by the roller 13. Further, since the floor surface installation bolt 18 is installed so as to project from the rear plate 2c of the outer box 2 to the rear, the refrigerator does not fall down due to an earthquake or the like even if it is installed in a place without a wall behind the refrigerator. When installed in a place where there is a wall behind the refrigerator and when the refrigerator is shipped, the caster body 15 has the roller support portion 17b of the frame 17 on the caster body support portion 14b as illustrated (solid lines in FIGS. 1 and 2). Since they are fixed by being brought into contact with each other and are housed in the lower surface of the substrate 14, there is no gap between the rear plate 2c of the refrigerator and the wall, and the installation area can be reduced and the kitchen space can be increased. In addition, the packaging at the time of shipping from the refrigerator can be downsized, and the cost can be reduced.

EFFECTS OF THE INVENTION As will be apparent from the above description, the present invention provides a substrate provided on the lower portion of the refrigerator body, and a frame that is rotatably supported on the lower surface of the substrate by a support pin in a position that does not project from the refrigerator and a position that does not project from the refrigerator. , A floor installation bolt provided at a protruding portion of the frame and a roller provided at a non-projecting portion of the frame, the floor installation bolt having a grip portion and having a height direction. Since it is attached to the frame with adjustable screws, even if it is installed in a place without a wall behind the refrigerator, by rotating the caster body, the floor installation bolt protrudes behind the rear plate and is installed. The refrigerator can be prevented from tipping over due to an earthquake, etc., and the roller also rotates (90 °), so that the rearward movement of the refrigerator can also be stopped by the roller. Further, when the refrigerator is moved by the roller, the roller does not project beyond the refrigerator main body, so that even if a weight is applied to the roller, the frame is not easily deformed and can be safely moved. Further, even if the weight of the refrigerator is added to the handle portion and the frame is bent, the rollers are located on the lower surface of the refrigerator body, so that the rollers support the body. Also, when installing in a place where there is a wall behind the refrigerator and when shipping the refrigerator, by rotating the caster with one touch and storing it in the lower surface of the substrate, a gap is created between the back plate of the refrigerator and the wall. It is possible to reduce the installation area and increase the kitchen space without causing any problems. In addition, the packaging effect at the time of shipment from the refrigerator can be reduced in size and the cost can be reduced.
