Description

  The present invention relates to a refrigerator.

  As shown in FIG. 9, the conventional height adjusting leg 11 is high enough to be grasped and turned by hand, and is intended only to be turned by hand. A rounded shape that is easy to hold by hand across the part and a shape without an angular groove was common. There exists patent document 1 as a prior art example.

  As shown in FIG. 10, the conventional refrigerator has a certain height which is suitable for turning the height adjusting leg by hand. The distance 21 from the refrigerator floor was large.

  Further, as shown in FIG. 11, there is an example of a height adjusting leg having a shape in which a hole 22 for engaging a tool is provided in a portion made of a resin material of the height adjusting leg so that the tool can be easily rotated. If it is not inserted sufficiently, it is difficult to rotate. There exists patent document 2 as a prior art example.

Japanese Utility Model Publication No. 60-75881 Japanese Patent Laid-Open No. 4-320783

  As shown in the prior art of FIG. 10 above, the one provided with the adjusting leg that is turned by hand for easy height adjustment has a large gap dimension 21 between the bottom of the refrigerator and the floor of the room. The internal volume was reduced. Therefore, in order to increase the food storage volume without changing the external dimensions of the refrigerator, it is conceivable to make the gap dimension between the bottom surface of the refrigerator and the floor surface of the room smaller than before. For that purpose, it is an indispensable condition to reduce the height dimension of the height adjusting leg. At that time, when the user moves the refrigerator by cleaning etc., the height adjustment leg is adjusted to raise the adjustment leg to float from the floor surface in order to reduce friction with the floor surface. Since the height is smaller than before, there is a problem that it is difficult to grasp by hand.

  The conventional height-adjusting leg that is turned by hand has a fine groove in the outer shape that touches the finger, and the height-adjusting leg whose height is reduced in that shape is rotated by hand. In this case, the operation is difficult because it is difficult to grasp by hand, and when the height dimension of the example of Patent Document 1 is reduced, the function of the height adjusting leg is difficult to be achieved.

  Further, when the height dimension of the height adjusting leg in FIG. 11 is reduced, a tool such as a screwdriver is inserted into the tool engaging hole and rotated, but the tool grip portion comes into contact with the floor surface. It becomes difficult to perform the rotation operation. Moreover, there is a possibility that the strength of the height adjusting leg itself is weakened by opening the hole.

  Furthermore, with the recent changes in housing conditions and eating habits, there is a great need for space-saving and large capacity in the refrigerator market. As mentioned above, a refrigerator is installed as a means to increase the internal volume without changing the external dimensions. A method of narrowing the space height between the floor surface and the refrigerator bottom surface is conceivable. As a result, the height of the gap between the drawer door height and the floor surface becomes smaller, and the support legs with casters for movement and the rotary height adjustment legs attached to the support legs have a height dimension higher than the conventional one. This can be solved by using a small and thin structure. For example, when the height of the adjusting leg is considered as high as the test finger of the IEC standard, it is considered to be as thin as 12 mm.

  However, when installing the refrigerator, the adjustment leg is rotated to fix the refrigerator to the floor, and when moving by cleaning, etc., the adjustment leg is detached from the floor. It is difficult to adjust it by hand.

  Since it is not easy for an adult's thick fingers to turn a thin adjustment leg, a refrigerator including an adjustment leg that is rotated using a tool nearby is required.

  It is an object of the present invention to be able to easily and safely rotate and adjust the height adjusting leg even if the height adjusting leg is reduced in order to increase the internal volume.

The present invention includes a refrigerator bottom front side fixed castors supporting leg member, and a height adjustable feet are screwed rotatably to the support leg member with the caster, the height adjustment leg body portion and has a screw portion, the body portion includes a central boss for fixing the screw portion in the center of the body portion, a plurality arranged the height adjusted circumferentially on the outer peripheral side of the central boss A round-projection-shaped hand-held portion with a round shape for rotating the leg, and the hand-held portion has a V-shaped recess at the intersection with the linear-shaped portion on the central boss portion side of the circular-projection shape The V-shaped recess is provided at a position that is smaller than the outer peripheral radius of the main body and larger than half the outer peripheral radius of the main body . Thereby, it was set as the refrigerator which is easy to latch a tool and was provided with several recessed parts, and can rotate a height adjustment leg with a small force when pushing a tool and rotating an adjustment leg.
In addition, the hand-held portion that is touched by a hand has a rounded and safe structure with a round shape, and the refrigerator is provided with several protrusions on the circular pattern that are easily accessible.
In addition, for example, when locking with a pointed tool such as a flat-blade screwdriver, the refrigerator has a structure that is more easily locked and can be expected to maintain the locked state.

  Further, the height adjusting leg is made of resin, and the main body height is 12 mm or less. Thereby, it was set as the refrigerator which is 12 mm which is the height which can be grasped with a hand.

  In addition, it was set as the refrigerator which provides the recess which a tool tends to latch when rotating a height adjustment leg using a tool. For example, the tip of the tool is typically represented by a flat-blade screwdriver, the width of the tip being about 6 mm to 8 mm is most popular, and the height of the locking part of the height adjustment leg is about 8 mm or more. If there is enough. In addition, when the height adjusting leg is rotated using a tool by a method other than that described above, the tool tip is locked in the recess in the manner of a so-called lever, and the tool is about 10 mm away from the tool tip. It was set as the refrigerator which provided the convex shape which can be pushed in the part of a shaft part side surface in the height adjustment leg outer periphery.

  According to the present invention, the internal volume can be increased, and the height adjusting leg can be rotated easily and safely.

Embodiments of the present invention will be described below with reference to the drawings.
