Hereinafter, a refrigerator door that can be opened and closed in both directions of the present invention will be described in detail with reference to the accompanying drawings.

3 is an external perspective view of the door 20 according to the present invention.

As shown, handles are provided at both ends, and rods 24 and 28 are provided at both ends of upper and lower surfaces of the refrigerator door 20. The rods 24 and 28 extend vertically, and reinforcing members 22 and 26 for supporting the rods 24 and 28 are provided as in the prior art. The rods 24 and 28 serve as rotating shafts as in the prior art and are fixed and do not move.

In order to insert and fix the refrigerator door 20, a load storage unit 32 is formed on the front surface of the refrigerator body. The rod storage part 32 is a structure for attaching and detaching the rods 24 and 28. The rod storage part 32 serves as a rotating shaft by fixing rods 24 and 28 at opposite positions which are not opened when the refrigerator door 20 is opened by pulling one handle. It has a structure that is described later.

In the center of the rod storage portion 32, a pair of balls 34 are kept in contact with each other. Springs are provided at both ends of the ball 34, respectively, so that the balls 34 keep in contact with each other. Although not described in detail, the structure and role of the rod storage unit (not shown) located at the bottom are essentially the same as those at the top, and thus, detailed description thereof is omitted. According to the present invention, since the internal structure of the refrigerator is not changed, things, such as food and drink, can be stored as in the prior art.

5 and 6 show an embodiment of the rod housing 32 according to the present invention. FIG. 5 is a cross-sectional plan view of the rod storage portion 32 viewed from the upper side, showing a case of the rod storage portion 32 having a receiving groove 38 protruding in a semicircular shape with a first half in a rectangular shape. A pair of springs 36 are provided in the rectangular interior of the rod housing portion 32 along the longitudinal direction, and a pair of balls 34 are inserted between the springs 36. The spring 36 exerts a sufficiently strong force on the ball 34 so that the rod 24 acting as the rotating shaft does not escape. However, when a person pulls with force, the ball 34 is opened and the rod 24 is separated to be able to open the refrigerator door 20.

Figure 6 is a side cross-sectional view of the rod 24 is inserted into the rod storage portion 32 of the present invention. As shown in the drawing, the rod 24 formed on the upper side of the refrigerator door 20 is inserted into the rod storage part 32 and is seated in the receiving groove 38. In addition, it can be seen that the positions of the spring 36 and the ball 34 are indicated by dotted lines. In the state in which the refrigerator door 20 is closed, the rod 24 is blocked by the ball 34 and is not separated.

Referring to the effect of the refrigerator door having the structure as described above are as follows. When the refrigerator door 20 is fully coupled to the refrigerator, the rods 24 and 28 at four corners of the refrigerator door 20 are inserted and fixed as shown in FIG. 6. Therefore, the refrigerator door 20 does not move and maintains a stopped state.

In this state, when pulling the handle to open the refrigerator door 20 on the right side (assuming the rod 24 side for convenience of explanation), the rod 24 on the pulling side overcomes the elastic force of the spring 36. Passed through the pair of balls 34 to the outside of the rod storage portion (32). At this time, the upper and lower rods 24 move simultaneously. However, since only the rotational force acts on the rod 28 in the opposite position, the rod 28 does not overcome the elastic force of the spring 36 and is blocked from moving to the outside by the ball 34, thereby leaving the rod 28. While this is prevented, only rotational force is applied. Therefore, the user can open the refrigerator door 20 by using the rotation axis where the rod 28 is located.

When the refrigerator door 20 is opened by pulling the handle on the rod 28 side, that is, the left side, the refrigerator door 20 opens to the left due to the opposite operation to the above description. Therefore, the user can open the refrigerator door 20 in any direction desired by the user.

7 and 8 show an embodiment of another rod storage portion 42 according to the present invention. As shown, a pair of rotary rods 44 are installed on the front of the rod storage portion 42 by the hinge shaft 46, the receiving groove 48 is formed on the rear, the receiving groove 48 A semi-circular locking member 54 having one end fixed by a spring s and a groove 52 formed in the middle is inserted into the body 50 of the rod housing 42 that wraps.

When the refrigerator door 20 is rotated while the refrigerator door 20 is completely coupled to the refrigerator main body, the protrusions 24a formed on the rod 24 are fitted into the grooves 52 so that the locking member 54 is a storage groove ( And configured to move to close 48 to prevent the rods 24 and 28 from disengaging. In this embodiment, in particular, when the locking member 54 is provided to open the refrigerator door 20, there is an advantage that the rods 24 and 28 acting as the rotating shafts can be completely prevented from coming off.

The pair of rotating rods 44 is operated to prevent the rods 24 and 28 from slipping off. That is, when the rod 24 is inserted as shown in the figure, the end is opened at the position indicated by the dotted line and rotates so that the rod 24 can be inserted into the receiving groove 48.

When the rod 24 is inserted, the end of the rotary rod 44 is returned to the position indicated by the dotted line again to prevent the rod 24 from being separated by its own weight. For this purpose, the size of the rod 24 and the restoring force for returning it to its original position must be determined according to the size of the rod 24. However, in this case it will be appreciated that the restoring force is possible as long as the rod 24 is not disengaged.

As shown in FIG. 7, when the rod 24 moves in the direction of the arrow to be seated in the receiving groove 48, the refrigerator door 20 is in a closed state. The rod 28 located in the opposite direction is also not inserted in detail but is inserted and seated like the rod 24.

8 is a partially exploded perspective view showing an example of the locking member 54 applied to the present invention. Reference numeral 24 denotes that the protrusion part 24a is formed on the rod 24 of the related art. Although not shown in detail, the rod 24 is the same as the rod shown in FIG. 3. The locking member 54 is installed in the main body 50 portion of the rod housing portion 42 constituting the receiving groove 48.

In detail, the right side of the main body 50 is a locking member 54 inserted into the main body 50 to perform a locking action, and the lower part of the main body 50 shows a middle portion of the main body 50. It is a side sectional view, and the lower right portion shows only the middle portion of the locking member 54.

In the main body 50, a groove is formed in the middle portion, and the locking member 54 is inserted into the groove so as to move horizontally. One side of the locking member 54 is a spring (s) is connected and the groove 52 is formed in the middle. The groove 52 is mated with the protrusion 24a of the rod 24. A portion of the locking member 54 having a groove 52 and a groove 52 is shown at the bottom. When fully engaged, the locking member 54 blocks the receiving groove 48 from the outside while moving horizontally while being inserted into the main body 50. When the receiving groove 48 is blocked in this way, when the refrigerator door 20 is opened, there is an effect that the rod 24 in the opposite position of the opening side is not detached to the outside.

The length of the locking member 54 is changed according to the opening / closing angle of the refrigerator door 20 and the size of the refrigerator door 20. When the opening of the refrigerator door 20 starts, the locking member 54 starts to rotate slightly. It should be sized to be able to perform locking action even if opened.

Also, in the drawing, the point to be around is the direction of the spring s connected to the locking member 54. This is to be connected in the opposite direction according to the positions of the rods 24 and 28 of the refrigerator door 20 to rotate to open the refrigerator door 20 to perform a locking operation. The spring s of the locking member 54 shown in FIG. 8 is a rod housing part to which the rod 28 is coupled because the spring s of the locking member 54 closes the receiving groove 48 when the protrusion 24a moves from left to right. 42) is preferable.

Referring to the effect of the refrigerator door 20 of the present invention having the structure as described above are as follows.

When the rods 24 and 28 are moved in the same state as in FIG. 7, the refrigerator door 20 is completely coupled to the refrigerator main body to stop the movement. When the rods 24 and 28 are fully engaged with the rod housing 42, the user pulls the door handle (for example, the handle of the portion in which the rod 24 is installed) attached to the refrigerator door 20 and the rod ( 24, the rod 24 is separated from the rod housing 42 while the rotary rod 44 is opened in the dotted line state in FIG. 7 as in the solid line state. At the same time, the refrigerator door 20 is opened using the rod 28 at the opposite position of the rod 24 as the rotation axis.

The rod 28 has the same protrusions (not shown), such as the protrusions 24a of the rod 24, are engaged with the grooves 52 of the locking member 54, so that the locking member 20 moves as the refrigerator door 20 moves. As the 54 moves, the circumference of the housing groove 48 into which the rod 28 is inserted is blocked. Accordingly, the rod 28 is prevented from being separated and the refrigerator is opened while the portion of the rod 24 is opened. In the open state of the refrigerator, since the locking member 54 blocks the rod 28 that serves as the rotating shaft, the refrigerator door 20 is stably fixed and rotated. When the refrigerator door 20 is closed, the locking member 54 is returned to its original position. When the locking member 54 is returned to its original position, the rods 24 and 28 are blocked from being separated by the rotation rod 44.

According to the present invention as described above has the advantage that the door can be opened and closed in both directions to open and close the door regardless of the installation position of the refrigerator.

Although the present invention has been described in detail only with respect to the embodiments described, it will be apparent to those skilled in the art that the present invention may be modified or changed within the spirit and scope of the present invention. something to do.
