The present invention relates to a hinge assembly of a kimchi reservoir having a ball bearing between an inner end of a body portion of a rotating member and an end of an elastic member in order to eliminate friction noise with a friction surface generated during tension / compression of an elastic member in the hinge assembly. will be.

In general, the opening and closing of the kimchi storage compartment is made through a door provided in the upper part of the storage compartment. The door is coupled to the main body by coupling the hinge assembly to the hinge receiving portion provided between the kimchi storage body and the end of the door, it is opened and closed in the vertical direction by the rotation of the hinge assembly.

The hinge assembly is provided with an elastic member therein to reduce the closing speed of the door to prevent the impact of a sudden closure, and to easily open the door with a small force.

For example, FIG. 1 of the accompanying drawings is a patent application No. 2003-101302 filed by the present applicant, a perspective view of the conventional kimchi storage and the hinge assembly, Figure 2 is a perspective view of the hinge assembly applied to the conventional kimchi storage. .

As shown in FIG. 1, the kimchi storage includes a main body 10 forming an appearance, a storage room 10a configured inside the main body 10 to store kimchi, and a lower portion of the storage room 10a. A door having a mechanical chamber (not shown) having a cooling device such as a compressor or a condenser, and a hinge assembly 30 fixed to the upper end of the main body 10 to seal the storage chamber 10a. It consists of 20.

In addition, hinge receiving portions 11 and 21 in which the hinge assembly 30 is accommodated are formed at the upper rear side of the main body 10 and the rear end of the door 20.

As shown in FIG. 2, the conventional hinge assembly 30 is rotatably coupled to the fixed member 31 and both ends of the fixed member 31, and moves in the axial direction of the fixed member 31 during rotation. The rotating member 32 and the elastic member 33 inserted into the rotating member 32 is compressed when the rotating member 32 is spaced apart from the fixed member 31 to limit the movement of the rotating member 32. ), And a fixed shaft 40 for integrally coupling the elastic member 33, the rotating member 32 and the fixing member 31.

The fixed shaft 40 is inserted along the axial hole of the fixing member 31 and the rotating member 32 to support the coupling between the fixing member 31 and the rotating member 32, as well as the flow of the elastic member 33 The washer 41 is inserted into both sides, and is fixed by the nut 42 at one end.

In this state, when the rotating member 32 is rotated and spaced apart in the axial direction with respect to the fixing member 31, the elastic member 33 is compressed as a result, and thus the movement of the rotating member 32 is limited. As the movement of the rotating member 32 is restricted, the door 20 has a structure in which the door 20 is gradually closed.

However, in the hinge assembly having a conventional elastic member as described above, as the rotating member rotates, friction between the end of the elastic member and the inner end of the rotating member in contact with the elastic member during tension / compression due to the large spring constant of the elastic member. There was a problem that friction noise caused by.

Accordingly, an object of the present invention is to solve the problem that the noise occurs in the friction surface of the elastic member and the fixing member as described above, a ball bearing between the inner end of the body portion of the rotating member and the end of the elastic member; It is provided with a hinge assembly of the kimchi storage to eliminate the friction noise by eliminating the direct friction with the friction surface of the rotating member by the rotation of the elastic member end to rotate the ball bearing coupled to the end of the elastic member at the same time. There is.

The present invention for achieving the above object, the fixing member is inserted into the main body-side hinge receiving portion and the rotating member coupled to the fixing member and inserted into the door-side hinge receiving portion and the elastic member is inserted into the inner end of the rotating member In the hinge assembly of the kimchi reservoir consisting of a member and a fixed shaft which is inserted through the fixing member, the rotating member and the elastic member to be integrally coupled, a plurality of ball support holes to which the spherical balls are coupled and supported are arranged at regular intervals. A hollow retainer having a ball support part formed through a dog, and a fixing part extending from the ball support part at a right angle and having one end of the elastic member guided and coupled / fixed thereto; A hollow first bearing rotating plate coupled to one end of the retainer and having a ball cloud portion on which the ball of the sphere is seated; It is seated on the other end opposite to the retainer, which is a position corresponding to the first bearing rotating plate, one end of which is composed of a hollow second bearing rotating plate which supports the end of the elastic member and the other end is seated and supported by the spherical ball. It is configured to include a ball bearing.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figure 4, looking at the decomposition of the hinge assembly according to the present invention,

The hinge assembly is symmetrically configured on both sides about the axis A-A line.

Therefore, hereinafter, only one portion of the hinge assembly according to the present invention will be described with reference to the accompanying drawings.

The fixing member 100 is cut in the center of the rod shape, the center has a connection function and at the same time is formed only the fastening portion 110 to be fitted to the rail formed on the body side hinge receiving portion (see Fig. 1, 11), Both ends are formed in the cylindrical hole 120 is inserted into the fixed shaft 500 in the axial direction in a cylindrical shape, the fastening portion 110 is inserted into the rail formed on the hinge receiving portion of the main body on the outer peripheral surface of both ends is blocked Is formed.

In addition, both ends of the fixing member 100 are formed with a driven part 130 recessed inwardly so that the spiral is inclined, and the rotating part 210 of the rotating member 200, which will be described later, rotates on the driven part 130, respectively. Possibly tilted.

Here, the rotating member 200 fitted to both ends of the fixing member 100, the rotating part 210 formed at one end to be inserted into the driven part 130 of the fixing member 100, the rotating part 210 It is made of a body portion 220 having a larger diameter than).

In addition, a spiral inclined surface is formed on an outer circumferential surface of the pivoting part 210 to correspond to the driven part 130 of the fixing member 100, and a fastening part 230 having a slot shape is formed on the outer side of the body part 220.
