The door 3 can be closed by its own weight by not affecting the rotation of the 10.

Although not shown separately through the drawings, each of the cam surfaces 15 and 44 does not form separate closing guide surfaces 15b and 44b, and ends of the opening guide surface 15a and the closing guide surface 15a of the closing guide surface 15b. (44b) The door 3 may be closed by its own weight while the ends of the side opening guide surface 44a are supported by each other.

In addition, in order to smoothly slide the cam surfaces 15 and 44 of the first cam 13 and the second cam 43, grease is formed on the cam surfaces 15 and 44 of the first cam 13 and the second cam 43. Lubricant, such as is applied to the outside of the second cam 43 of the cylindrical outflow preventing member for suppressing the lubricating oil applied to each of the cam surface (15,44) to flow out of each cam (13,43) 70 is provided. (See FIGS. 3 to 5)

The leakage preventing member 70 is coupled to the outer surface of the second cam 43 is forced to be pressed into the opening guide surface 15a of the cam surface 15 of the first cam 13 and the cam surface 44 of the second cam 43. In the state where the guide surface (44a) is in contact with each other is provided to accommodate the first cam 13 therein, the leakage preventing member 70 is installed on the outer surface of the first cam 13 on the contrary, the second cam ( 43) may be provided to accommodate the inside.

Meanwhile, referring back to FIGS. 3 to 5, the second hinge shaft 20 has a cover portion 34 at an end opposite to the door fastening portion 21 extending into the second accommodating portion 31b of the housing 30. The support jaw 22 is formed to be caught by the axial coupling hole 34a and supported on the inner surface of the cover portion 34, and the damping portion installed in the second accommodating portion 31b of the housing 30 supports the cam driving portion. One end is inserted into the center side of the fixing member 80 to connect the fixing member 80 and the fixing member 80 and the second hinge shaft 20 provided to be supported by the 60, and the other end of the second hinge shaft ( 20 and a guide rod 90 provided to be rotatably inserted at the center side, and one end is fixed to the fixing member 80 in a state wound around the guide rod 90 and the other end is connected to the second hinge shaft 20. It is configured to include a second elastic member 100 provided to be fixed.

Here, the first insertion grooves 81 and the second insertion grooves 22a are formed at the centers of the fixing member 80 and the second hinge shaft 20 for insertion of both ends of the guide rod 90, respectively. As the elastic member 100, a normal torsion spring is employed.

In addition, the rotation preventing protrusion of a predetermined length along the longitudinal direction of the housing 30 on the inner surface of the body portion 32 of the housing 30 of the fixing member 80 side so that the fixing member 80 does not rotate inside the second accommodation portion. 31b-1 is formed, the fixing member 80 is formed with a rotation preventing groove 82 which is coupled to correspond to the anti-rotation projection (31b-1).

In addition, the guide rod 90 is for guiding the second elastic member 100. Unlike the present embodiment, the guide rod 90 may be formed integrally with the fixing member 80 or may be integrally formed with the second hinge shaft 20. When the second elastic member 100 is integrally formed with the fixing member 80 to allow the twisting of the second elastic member 100, the end portion of the second hinge shaft 20 must be inserted into the second hinge shaft 20 to be rotatable. When formed integrally with the second hinge shaft 20, it should be provided to be rotatable with the second hinge shaft 20.

The damping part transmits a rotational resistance generated by the torsional stress of the second elastic member 100 to the door 3 through the second hinge shaft 20 when the door 3 is rotated to be closed in the open state. By reducing the rotational speed of the door 3 so that the door 3 can be closed smoothly.

On the contrary, when the door 3 is rotated to open in the closed state, the damping part is twisted and then the second hinge shaft 20 is closed by the restoring force of the second elastic member 100 to be restored to its original state. It also has the advantage that the opening force of the door (3) is increased by allowing the 3) to rotate in the opening direction.

That is, to explain in more detail, the second elastic member 100 is the body 101 of the central portion provided to be wound around the guide rod 90, and the first and second fixing parts 102 and 103 provided at both ends of the body 101, respectively. ), Wherein the first fixing part 102 is fixed to the first fixing groove 83 provided at one side of the center of the fixing member 80 and the second fixing part 103 is the second hinge shaft 20. It is provided to be fixed to the second fixing groove (22b) provided on one side of the center of the center, the second elastic member 100 is maintained in the original state without twisting in the state in which the door (3) is open and the door (3) is closed It is arranged to be twisted in a closed state.

Therefore, when the door 3 in the open state is rotated in the closing direction, the second fixing part 103 of the second elastic member 100 is moved by the second hinge shaft 20 according to the rotation of the door 3. The first fixing part 102 of the second elastic member 100 fixed to the fixing member 80 is rotated together with the second hinge shaft 20 when the second hinge shaft 20 rotates. While maintaining the fixed state, the second elastic member 100 is twisted, and the rotational resistance of the door 3 is increased by the torsional stress of the second elastic member 100, and the door can be smoothly closed.

On the contrary, when the door 3 in the closed state is rotated toward the open side, the second hinge shaft 20 is rotated in the opening direction of the door 3 by the restoring force of the twisted second elastic member 100. The force is applied so that the door 3 can be easily opened by less external force.

In addition, such a hinge device 5 is connected between the door 3 and the main body 2 more stably in a state where the door 3 is closed so that the door 3 is supported on the upper surface of the kimchi refrigerator main body 2. Since the hinge device 5 is installed so as to rotate the second hinge shaft 20 opposite to the opening direction of the door 3, the second elastic member 100 is twisted. At this time, the second hinge shaft (2) is restrained by the restoring force of the second elastic member 100 that is twisted in the process of coupling the door fastening portion 21 of the second hinge shaft 20 to the door 3 side coupling portion 3a. 20 is difficult to couple the door fastening portion 21 of the second hinge shaft 20 to the engaging portion 3a of the door 3 by attempting to rotate in the opposite direction in which the second elastic member is to be restored.

Therefore, as shown in Figure 9, one side of the shaft coupling hole (34a) of the cover portion 34 is fixedly coupled to one end of the housing 30, the rotation is fastened from the outside of the cover portion 34 into the housing 30 A fastening hole 34b for fastening the prevention pin 110 is formed, and the second hinge shaft 20 on one side of the support jaw 22 corresponding to the prevention pin 110 is formed into the housing 30 through the fastening hole 34b. A locking portion 22c is formed to be caught by the rotation preventing pin 110 to be inserted to prevent rotation of the second hinge shaft 20.

In this state, the anti-rotation pin 110 is rotated in one direction so that the second elastic member 100 is twisted in the housing 30 through the fastening hole 34b. When the engaging portion 22c is caught by the end of the anti-rotation pin 110 inside the housing 30, the second hinge shaft 20 rotates in the direction in which the second elastic member 100 is to be restored. It is not possible to maintain the twisted state of the second elastic member 100.

For reference, in the present embodiment, the locking portion 22c is provided in the shape of a groove into which the end of the anti-rotation pin 110 can be inserted, but the locking portion 22c is caught by the anti-rotation pin 110 and is second. Even if the projection is provided in the form of a hole, such as the fastening hole 34b of the cover portion 34 is simply provided in the range that can prevent the rotation of the hinge shaft (20). Irrelevant

In addition, the anti-rotation pin 110 includes the door member 3b of the second hinge shaft 20 fitted to the coupling part 3a of the door 3, and then the cover member 3b is coupled to the coupling part 3a. Prior to the fastening, the cover member 3b is removed to the outside of the cover part 34 so as not to interfere with the fastening of the coupling part 3a. Thus, the connection between the door 3 and the main body 2 is completed. The two hinge shafts 20 allow the second elastic member 100 to be twisted or restored while rotating in one direction or the opposite direction according to the opening and closing operation of the door 3.

Next will be described the operation of the storage hinge device according to the present invention configured as described above.

When the user opens or closes the door 3 of the kimchi refrigerator, the first hinge shaft 10 and the second hinge shaft 20 connected to the door 3 rotate together with the door 3, wherein the door 3 ) Is easily opened or closed by the rotational force of the first hinge shaft 10 is provided by the cam driving unit.

That is, when the first hinge shaft 10 is rotated, the first cam 13 provided on the first hinge shaft 10 is also rotated. In this case, the movable member 40 is applied to the elasticity of the first elastic member 50. Since the first cam 13 has a force to move toward the first cam 13, and the second cam 43 of the moving member 40 is in contact with the first cam 13, the first hinge shaft 10 is connected to the door ( 3) When the second cam 43 of the moving member 40 rotates in the opening or closing direction, the first cam of the first hinge shaft 10 moves forward along the longitudinal direction of the first hinge shaft 10. 13) Pressurize. Therefore, the door 3 is easily formed by the relationship between the frictional force generated between the first cam 13 and the second cam 43 by the pressing force of the first elastic member 50 and the weight of the door 3. Opening and closing is possible.

In more detail, when the door 3 of the kimchi refrigerator is opened at a predetermined angle or more, and is located in the opening section of FIG. 2, as shown in FIGS. 4 and 7, the opening guide surface of the inclined second cam 43 is shown. 44a and the opening guide surface 15a of the first cam 13 are in contact with each other, and in this state, the second cam 43 of the moving member 40 moves toward the first cam 13 while the first cam is moved. Since the opening guide surface 15a of 13 is pressed, the first hinge shaft 10 is forced to rotate in the opening direction of the door 3, so that the door 3 is easily opened. In addition, when the elastic force of the first elastic member 50 is properly adjusted so that the force to rotate in the direction in which the first hinge shaft 10 is opened and the force to close the door 3 by its own weight are approximately equal to the door ( 3) may remain stationary within the open section.

And when the opening angle of the door 3 becomes below a predetermined angle and the door 3 is located in the closing section of FIG. 2, as shown in FIG. 5 and FIG. 8, the closing guide surface 44b of the 2nd cam 43 is shown. ) And the closing guide surface 15b of the first cam 13 are in contact with each other, so that the elasticity of the first elastic member 50 does not affect the rotation of the first hinge shaft 10. Therefore, in the range of the short force section, the first hinge shaft 10 rotates in the closing direction of the door 3 by the weight of the door 3 and the door 3 is closed while rotating by itself.

In addition, when the door 3, which has been opened in this way, is closed, the resistance of rotation of the second hinge shaft 20 is increased by the damping part, and the door 3 is smoothly closed.

In detail, when the door 3 in the open state is rotated in the closing direction, the second fixing part 103 of the second elastic member 100 may have a second hinge shaft (2) according to the rotation of the door 3. 20 rotates together with the second hinge shaft 20, and when the second hinge shaft 20 rotates, the first fixing part of the second elastic member 100 fixed to the fixing member 80 ( While maintaining the fixed state 102, the second elastic member 100 in its original state is twisted, and the rotational resistance of the door 3 is increased by the torsional stress of the second elastic member 100. (3) can be closed smoothly.

On the contrary, when the door 3 in the closed state is rotated toward the open side, the second hinge shaft 20 is rotated in the opening direction of the door 3 by the restoring force of the twisted second elastic member 100. Force, which allows the door 3 to be easily opened by less external force.

As described above, the storage hinge device 5 according to the present invention is simplified as compared to the conventional configuration, since the hinge unit, which is conventionally provided with two hinge units, is integrated into a single unit, thereby facilitating the assembly of the hinge device 5. Due to the damping action of the damping part, the door 3 can be closed smoothly, so that a large shock is not generated when the door 3 is closed.

In addition, as shown in Figures 10 and 11 showing a second embodiment of a storage hinge device according to the present invention, in the second embodiment according to the present invention, the second elastic member is elastic instead of the torsion spring A torsion bar 100 'provided in the shape of a rod is adopted.

The torsion bar 100 'is provided such that the first and second fixing parts 102' and 103 'at both ends are coupled to the centers of the fixing member 80 and the second hinge shaft 20, respectively. Compared to the first embodiment, a separate guide rod 90 for guiding the second elastic member is provided between the second hinge shaft 20 and the fixing member 80, wherein the second hinge shaft 20 At least one chamfer 102'a, 103'a is formed in each fixing portion 102 ', 103' at both ends of the torsion bar 100 'so that the torsion bar 100' is twisted by rotation. Second fixing of the first fixing groove 83 'and the second hinge shaft 20 of the fixing member 80 to which the fixing portions 102' and 103 'of the torsion bar 100' are inserted.
