When the door of the refrigerator is opened, even if the center of gravity of the refrigerator acts on the front, the refrigerator will not fall to the front position.

Fig. 6 is a perspective view of the support leg 4 of the refrigerator of Fig. 1 viewed from the upper side in a state where the adjustment leg 6 has been removed from the support leg 4, and Fig. 7 is a perspective view of the support leg 4 of Fig. 6 as viewed from the bottom surface side. .

The adjustment leg 6 is composed of, for example, a resin-made adjustment script body 80 and a screw portion 5. The adjustment script body 80 has a cylindrical shape and is, for example, a circular shape having a diameter of about 45 mm when viewed from the upper side. The adjustment leg 6 is provided such that the screw portion 5 protrudes on the upper surface side of the circular center portion of the adjustment script body 80, and the screw portion 5 is screwed to the nut portion 82 welded to the support leg member 81, and The refrigerator can move up and down. The screw portion 5 that protrudes from the adjustment foot upper portion 88 has a central axis that is perpendicular to the adjustment foot bottom portion 87, and is fixed to the adjustment script body 80 made of resin, for example, by integral molding. The threaded portion 5 is in a state before being integrally formed on the adjustment script body 80, and includes a threaded portion 5a, a flanged portion 5b, and a shaft portion 5c. When the screw portion 5 is integrated with the adjustment script body 80, the flange portion 5b and the shaft portion 5c are embedded in the shape of the adjustment script body (see Fig. 10).

The bottom 87 of the adjustment foot is in contact with the setting surface of the refrigerator and supports the weight of the refrigerator. When the refrigerator is installed, the user of the installer or the refrigerator holds the circular adjustment foot side portion 86 of the adjustment foot 6 and rotates it, whereby the height of the adjustment foot 6 can be adjusted from the support foot 4 and can be matched with the refrigerator. Set the state of the face and set the refrigerator horizontally. As shown in Fig. 6, the adjustment leg side portion 86 is formed in a circular shape when the adjustment leg 6 is viewed from above. The outer peripheral portion of the circular adjustment leg 6 is used as the adjustment leg side portion 86. The adjustment leg side portion 86 corresponds to the "outer peripheral portion" in the present invention. In the adjustment foot side portion 86, in order to make it difficult for the user or the like to slide while holding the outer circumference of the adjustment leg 6, the uneven shape extending in the vertical direction of the adjustment foot bottom portion 87 is provided. Further, in the adjustment leg 6, a tool engagement portion 83 having an opening in the adjustment leg side portion 86 is provided, and when it is difficult to hold the adjustment leg side portion 86 by hand or the like, the tool can be inserted and rotated.

Fig. 8 is a front view showing a state in which the adjusting leg 6 is attached to the support leg 4, and Fig. 9 is a side view of Fig. 8. Fig. 10 is a cross-sectional view showing a cross section of the Z-Z portion of Fig. 8 and showing a state in which the adjusting leg 6 is attached to the support leg 4.

In the adjustment leg 6, four tool engagement portions 83 are radially provided around the screw portion 5. The tool engagement portion 83 has a width that can be inserted into, for example, a bar-shaped article having a diameter of about 6 mm, and can be used, for example, as a work hole for inserting a generally sold screwdriver from the outer peripheral side of the adjustment leg 6 substantially horizontally.

In the tool engagement portion 83, for example, a screwdriver is inserted, and a load is applied to the grip portion of the screwdriver in the rotational direction of the adjustment leg 6, whereby a large torque can be applied to the adjustment leg 6. Depending on the state of the installation surface of the refrigerator, there is a case where the friction between the bottom surface of the adjustment leg 6 and the installation surface is large, and the outer circumference of the adjustment foot 6 is difficult to rotate. Further, as the size of the refrigerator is increased, the weight of the refrigerator becomes heavier, and the frictional force between the foot bottom 87 and the installation surface is increased due to the weight of the refrigerator. In this case, the installer of the refrigerator or the user of the refrigerator can use the tool around it to easily rotate the adjustment foot 6 to adjust the height, and the refrigerator can be horizontally disposed.

The tool engagement portion 83 is formed from the outer circumference of the adjustment leg 6 toward the screw portion 5, and the outer circumferential surface of the adjustment leg 6 serves as the start end of the tool engagement portion 83 and reaches the portion of the adjustment leg 6 that is embedded in the thread portion 5. Front becomes tool engagement 83 terminal. According to this configuration, the portion of the screw portion 5 in which the adjustment script body is embedded (for example, the flange-shaped portion 5b and the shaft portion 5c) and the tool engagement portion 83 do not overlap in the height direction of the adjustment leg 6, so that adjustment can be performed. The height of the foot 6 becomes lower. Therefore, the internal volume of the refrigerator is not reduced by the adjustment of the foot 6, and the height adjustment work can be easily performed using a tool or the like on the market.

Further, the tool engagement portion 83 of the present embodiment is, for example, a groove-shaped upper groove 84 which is opened from the outer circumference by about 10 mm. A bottom hole 85 which is opened at a lower side of the tool engagement portion 83, for example, about 5 mm in the vicinity of the center of the adjustment leg 6, is formed in a shape of a hole drilled under the resin of the upper side of the adjustment leg 6. When the upper groove 84 and the bottom hole 85 are viewed from the adjustment foot upper portion 88 side, the center line of the upper groove 84 and the center line of the bottom hole 85 are arranged on the same straight line or substantially the same straight line, and the upper groove 84 and the bottom hole 85 are attached. When the tool engagement portion 83 is viewed from the outer peripheral side of the side surface of the adjustment script body 80 toward the center, the hole is inserted into the tool (see FIG. 8). The wall surfaces of the groove side surfaces constituting each of the upper groove 84 and the bottom hole 85 are connected to each other to constitute a continuous wall surface. However, as long as the tool can be inserted and biased, for example, because of ease of processing or the like, a step may be allowed between the wall surface of the upper groove 84 and the wall surface of the bottom hole 85. The tool is inserted into the tool engaging portion 83, and when the load is applied by the turning of the threaded portion 5, the tool is in contact with the wall at 2 o'clock, and the force of the user of the refrigerator or the user of the refrigerator is applied to the grip portion of the tool from the tool and the wall surface. The two-point contact portion acts to make the adjustment foot 6 easy to rotate.

Further, the tool engagement portion 83 has a portion in which the upper groove 84 opened at the upper side and the bottom hole 85 which is opened at the lower side are overlapped. It is the bottom of the upper groove 84 which is open on the upper side and the bottom of the part which is open on the lower side. The portion where the portion of the hole 85 overlaps is a hole portion 89 penetrating in the lower direction of the adjustment leg 6 (see FIG. 10).

Hereinafter, the effect of the tool engagement portion 83 of the present embodiment including the upper groove 84 and the bottom hole 85 will be described.

In the case where the tool engagement portion 83 is formed only in the upper groove 84, since the portion that receives the tool on the upper side does not exist, the front end of the inserted tool is easily separated from the upper side of the adjustment leg 6, and it is difficult to adjust from the grip portion of the tool. The steering force of the foot 6 is not suitable for adjustment work. By making the size of the upper groove 84 in the depth direction larger than the diameter of the insertion tool, the tool can be prevented from falling off the groove, but in this case, the height of the adjustment leg 6 becomes high, and the internal volume of the refrigerator is lost.

Moreover, in the case where the tool engagement portion 83 is formed only by the groove drilled on the bottom surface side, it is necessary to insert the tip end portion of the tool into the tool engagement portion 83 along the installation surface of the refrigerator. Since the grip portion of the general tool is thicker than the front end, when the front end portion of the tool is inserted into the tool engagement portion 83, it is necessary to insert the front end portion of the tool toward the installation surface side and insert the tool engagement portion 83 under the inclination of the tool. . When the depth direction dimension of the groove drilled on the bottom surface side is deeper than the radius of the grip portion of the tool, the tool can be inserted horizontally with the installation surface, but the radius of the grip portion of the worker having only the tool is larger than that on the bottom surface side. In the case of a tool having a large depth direction in the groove of the drill, it is difficult to insert the tool into the groove. Further, when the depth direction dimension of the groove drilled on the bottom surface side is determined in consideration of the size of the grip portion of the plurality of tools, the height of the adjustment leg 6 becomes high, and the internal volume of the refrigerator is lost.

On the other hand, in the tool engagement portion 83 of the adjustment leg 6 of the refrigerator of the present embodiment, the tool distal end side is a resin wall 90 on the upper surface side of the adjustment leg 6, because the wall 90 on the upper side of the adjustment leg 6 is restricted. The action at the front of the inserted tool, It is difficult to get out of the slot at the front end of the tool at the time of operation. The side of the grip portion of the tool inserted into the tool engagement portion 83 is attached to the wall 91 on the bottom surface side of the adjustment leg 6, and since it is opened on the upper surface side of the adjustment leg 6, when the tool is inserted from the outer peripheral side of the adjustment leg 6 toward the center, The front end of the tool can be inserted obliquely from the upper side of the adjustment leg 6 toward the setting surface side. Thereby, even if the outer diameter of the tool grip portion is thicker than the front end of the tool, it is easy to insert the tool into the tool engagement portion 83, and the range of selection of the tool is wide when the adjustment leg 6 is rotated.

In addition, when dust or the like enters the tool engagement portion 83, it is dropped from the bottom hole 85, so that dust or the like is hard to stay in the tool engagement portion 83, and even if dust or the like stays, it is caused by the tool engagement portion. The center side of the 83 is pushed in, and it can be dropped from the bottom hole 85, so that it is easy to remove.

Further, the tool engagement portion 83 may be configured to have no hole portion 89 penetrating in the downward direction of the adjustment leg 6, but the hole portion 89 has a shape of the resin molded portion of the adjustment script body 80. The cut portion has an advantage that the mold construction that can be used for resin molding becomes simple. Moreover, in the case of mechanical processing, it also has the advantage of being easy to process;

Further, the tool engagement portion 83 may be configured such that the upper groove 84 is closed by the wall 90 on the upper side of the adjustment foot, and the adjustment leg 6 is provided from the adjustment leg side portion 86 in which the opening is provided to the adjustment leg side portion 86. The transverse hole extending through the threaded portion 5 communicates with the bottom hole 85. Further, the tool engagement portion 83 may be configured to communicate with the lateral hole, the upper groove 84, and the bottom hole 85 that are opened to the adjustment leg side portion 86 from the outer circumferential side of the adjustment leg 6 in order. In these configurations, it is also possible to obtain an effect that the dust or the like is hard to be retained and the dust is easily removed.
