In this case, when referring to the hinge assembly of the present invention, the reference numerals of the hinge assemblies are denoted by H, and in the embodiments, the reference numerals of the hinge assemblies according to the embodiments are indicated by H ₁ , H ₂ , H ₃ , and the like. Add one in H ₄ .

4 to 8, the first embodiment of the hinge assembly H according to the present invention shows the simplest form of the gist of the configuration pursued by the present invention.

That is, the hinge assembly H ₁ according to the first embodiment is provided with a pivoting portion 61 for rotation on one end of the outer peripheral surface, and on the outer peripheral surface of the central protrusion 62 having a larger diameter than the pivoting portion 61. A rotating member 60 having a fastening guide part G ₁ formed in the entire longitudinal direction and a through hole 63 formed in the longitudinal direction thereof; At least one end is formed with a receiving groove 52 into which the rotating part 61 of the rotating member 60 is inserted, and the driven part engaged with the rotating part 61 opposite to the inner circumferential surface of the receiving groove 52. 51 is provided, the cylindrical fixing member through which the through hole 53 is formed in the longitudinal center through the receiving groove 52 and the fastening guide portion G ₂ is formed in the entire longitudinal direction of the outer circumferential surface. 50; A spring member (70) inserted into an opposite side of the rotating part (61) of the rotating member (60) to impart an elastic restoring force and a repulsive force to the rotating member (60) accommodated in the fixing member (50); It is inserted through the through holes (53, 63) of the fixing member 50 and the rotating member 60 to support the mutual coupling between the rotating member 60 and the fixing member 50, as well as the spring member 70 It consists of a fixed shaft (80) to restrict the flow.

Here, when the hinge assembly (H) is mounted between the door 2 and the main body 1 of the kimchi storage, the rotating member 60 is rotated forward and backward according to the opening and closing of the door 2, the left and right reciprocating straight line It is a member to exercise, the fixing member 50 is to serve to transmit the rotational force according to the opening and closing of the door 2 to the rotating member 60 while receiving and fixing one end of the rotating member 60. .

In addition, the spring member 70 is provided on one side of the rotating member 60 to be compressed and restored by the rotating member 60 which is left and right reciprocally linearly moving forward and reverse as the door 2 is opened and closed. Through this serves to cushion (or alleviate) the sudden closure of the door (2).

In addition, the fixed shaft 80 has a shape of a tension bolt, and as described above is inserted through the through holes (53, 63) of the fixing member 50 and the rotating member 60 and the rotating member 60 and While supporting the mutual coupling between the fixing member 50 serves to limit the flow of the spring member (70).

That is, the fixed shaft 80 is a center through-hole coincided with the fixing member 50 and the rotating member 60 in the state in which the rotating member 60 and the spring member 70 are assembled to the fixing member 50 in order. Inserted through (53, 63), and then fixed to the nut 81 is fitted to the end.

Of course, at this time, a washer 82 is provided between the spring member 70 so that the elastic restoring force and the repulsive force of the spring member 70 can be expected during the operation of the hinge assembly H. As a result, the fixed shaft ( 80) will limit the overall length of the hinge assembly (H).

Looking at the configuration of the hinge assembly (H) according to the present invention in more detail, the driven portion 51 and the rotating portion 61 of the rotating member 60 of the fixing member 50 is formed to face each other And have a structure that can interlock with each other.

Looking at a more specific embodiment of the rotating member 60 and the fixing member 50, as shown in Figure 5, the rotating portion 61 of the rotating member 60 is a through hole of the rotating member 60 (63) The longitudinal direction after the incision surface (C ₁ ) formed by horizontal incision along the longitudinal direction of the outer circumferential surface, and the section (t ₁ ) with a predetermined width gradient in the radial direction at the tip of the incision surface (C ₁ ) It has a slope (T ₁ ) formed to be inclined spirally along.

At this time, the cutting surface (C ₁ ) and the inclined surface (T ₁ ) has a structure formed a plurality of symmetrical 180 ° around the through-hole (63).

In addition, the end portion where the inclined surface T ₁ ends is formed to have a horizontal plane by forming a bent step section d ₁ , r ₁ different from the inclined line of the inclined surface again.

As shown in FIG. 6, the driven part 51 of the fixing member 50 corresponds to the structure of the pivoting part 61 as described above, so that the rotating member 60 is attached to the fixing member 50. Spiral inclined surface (T ₂ ) which is in contact with the inclined surface (T ₁ ) of the rotating part (61) to the inner peripheral surface of the receiving groove (52) of the fixing member (50) so as to engage and interlock when fully inserted close contact. At the same time as this is formed, it has a cutting surface C _{2 which} is horizontally cut along the longitudinal direction at one end of the inclined surface T ₂ .

In addition, the inclined surface T ₂ and the incision surface C ₂ are formed in plural in a 180 ° symmetrical structure.

Of course, a gradient section t ₂ is also formed in the driven part 51 such that the gradient section t ₁ of the pivoting part 61 is in surface contact, and the stepped sections d ₁ and r ₁ of the pivoting part 61 are formed. Protruding sections (d ₂ , r ₂ ) are provided so as to be in surface contact with ().

Particularly, in the case of the protrusion section r ₂ formed in the driven part 51, the incision surface C ₂ is formed on one side thereof, and the front end thereof is protruded compared to the inclined surface T ₂ . When the rotating member 60 is fully inserted into the fixing member 50, the rotating member 60 is brought into contact with the stepped section r ₁ of the rotating part 61, and the rotating member 60 rotates. Contact with the gradient section t ₁ of the rotating part 61 when exiting the inclined surface T ₂ formed on the driven part 51 of the fixing member 50 (at this time, the rotating member is rotated 90 ° The rotation member 60 has a boundary function that serves as a stopper so that the rotation member 60 can no longer rotate.

The reason why the plurality of inclined surfaces T ₁ and T _{2 of} the rotating part 61 and the driven part 51 are formed to be symmetrical by 180 degrees is that the door 2 is opened approximately 90 degrees from the upper surface of the storage chamber 3. This is because it is desirable to form a plurality of symmetrical in terms of durability and at the same time.

As described above, the inclined surface T ₁ of the pivoting part 61 and the inclined surface T ₂ of the driven part 51 are coupled to each other so that the inclined surface T ₁ of the pivoting part 61 is in contact with each other.

At this time, when the spiral inclined surface (T ₁ , T ₂ ) is formed in the reverse direction (counterclockwise), the inclined surface T ₁ of the rotating member 60 is the inclined surface T ₂ of the fixing member 50. out pushed by the inclined surface of the out said spring is formed in a direction to compress the member 70, a forward inclined surface (T ₁₎ the fixing member 50 of, the rotary member 60 when rotated in the (clockwise) (T ₂ R) is formed to be inserted into the fixing member 50 in the inward direction and is formed in a structure that receives elastic restoring force from the spring member 70.

Here, when the hinge assembly H is assembled between the door 2 and the main body 1, the reverse direction (counterclockwise direction) means the direction in which the door 2 is closed, and the forward direction (clockwise direction) Denotes the direction in which the door 2 is opened.

On the other hand, in forming the inclined surface of the rotating part 61 and the driven part 51, the spiral inclined surface (T ₁ , T ₂ ) in the entire longitudinal direction at the tip of the horizontal cut incision (C ₁ , C ₂ ) The reason for forming the spiral inclined surfaces T ₁ and T _{2 in the} longitudinal direction after providing a predetermined width gradient section t ₁ and t _{2 in the} radial direction without forming them is as follows.

That is, when the hinge assembly (H) is mounted between the door (2) and the main body 1 when the door 2 is opened and closed to operate, as described above, the rotating member (60) Of the inclined surface T ₁ is pushed out by the inclined surface T ₂ of the fixing member 50 to compress the spring member 70, and the elastic repulsive force of the spring member 70 gradually increases to lower the door 2. The closing speed of the door 2 is alleviated in proportion to its own weight, and when the speed is alleviated at a constant speed, the door 2 is prevented from descending rapidly due to its own weight to be closed.

However, at this time, while the door 2 is completely closed, such a constant and descending speed (downward speed of the door according to the relationship between the self-weight force of the descending door while the elastic repulsive force of the spring member increases gradually) ) Is not preferable in terms of the sealing property of the door 2, so that when the door 2 reaches a predetermined height (within about 5 to 10 degrees from the upper surface of the storage compartment 3), the spring member 70 It is preferable that the door 2 is rapidly closed by its own weight while the self weight of the door 2 becomes instantaneously larger than the elastic repulsive force.

Therefore, the reason for having the gradient sections t ₁ and t ₂ formed in the radial direction on the inclined surfaces T ₁ and T ₂ is due to the weight of the door 2 at a predetermined height before the door 2 is completely closed. It is to close rapidly and to improve the sealing property of the door (2).

At this time, the gradient section (t ₁ , t ₂ ) is preferably designed to be a height that can move the distance within 5 ~ 10 ° before the door 2 is completely closed, this is the designer's choice door 2 It is preferable to design in accordance with the most optimal condition in consideration of the self weight of the

In addition, in the structure in which the rotating part 61 of the rotating member 60 has a spiral inclined surface T ₁ , an oil capable of temporarily storing and supplying oil, which is a lubricant, is provided on the through hole 63 of the rotating member 60. Preferably, the feed groove 64 is formed.

That is, the oil supply groove 64 stores the oil, which is a lubricant for some time, when the inclined surface T ₁ of the pivoting part 61 and the inclined surface T ₂ of the driven part 51 are engaged with each other. It serves to store and supply oil for smooth operation without friction.

In addition, the fastening guides G ₁ and G ₂ formed on the outer circumferential surfaces of the rotating member 60 and the fixing member 50 are hinge assemblies H in a state in which the rotating member 60 and the fixing member 50 are assembled to each other. It is provided for fastening and fixing with the relative fastening portion for the operation of), is formed in a structure capable of a conventional fitting coupling method.

That is, when the fastening ribs (m ₄ ) protruding from the mating fastening portion are formed, they are formed in the form of fastening grooves g ₁ and g ₂ recessed inwardly and are disposed at regular intervals on the outer circumferential surface, and are recessed inwardly in the relative fastening portion. When the fastening groove (not shown) of the form is formed, the fastening ribs (m ₁ , m ₂ ) protruding from the outer peripheral surface has a structure that is arranged at regular intervals on the outer peripheral surface (see Figs. 10 and 17).

In particular, when the fixing member 50, rotation member 60 is completely pressed to be assembled, it is entered into the guide portion (G ₂₎ of the engaging guide portion (G ₁₎ and the fixing member 50 of the rotating member 60 They are placed side by side on a straight line.

As such, the fastening guide parts G ₁ and G ₂ should be placed in a straight line side by side when the hinge assembly H, which will be described later, is installed and assembled. It is to be fastened along the fastening guide fixing part (M ₁ , M ₂ ) formed in the main body).

In addition, the stopper having the same shape as the fastening guides (G, G) in any one of the outer peripheral surface of the rotating member 60 and the fixing member 50 of the hinge assembly (H ₂ ) is provided with a plurality of rotating members (60). Part E is provided.

The stopper part (E) is intended to be a stopper function when the hinge assembly (H ₂ ) is fastened and installed in a fastener, which will be described in detail in the installation structure described later.

In addition, in the case of the fixing member 50, it is preferable to manufacture in a cylindrical shape using a high strength metal or hard synthetic resin material, the fastening guide part in terms of reducing the weight and material of the fixing member 50 ( It is preferable that the whole skin of the outer circumferential surface except for G ₂ ) is processed (see FIG. 18).

Of course, even if the weight processing on the outer peripheral surface of the fixing member 50, it is natural that there is no problem with respect to the structural strength required for the operation and operation of the overall hinge assembly (H), but, the production cost and the hinge It may be very effective and desirable in terms of lowering the weight of the assembly H itself.

On the other hand, while having a basic configuration of the first embodiment of the present invention by changing the engagement structure of the rotating part 61 and the driven part 51 to provide a hinge assembly (H) having a screw coupling structure commonly known in common. You may.

That is, in the first embodiment of the present invention by modifying the structure of the rotating part 61 and the driven part 51, the driven part 51 of the rotating part 61 and the fixing member 50 of the rotating member 60 An embodiment having a structure in which is screwed is shown in FIG.

As shown in FIG. 12, spiral threads S ₁ and S ₂ are respectively formed on the driven part 51 of the fixing member 50 and the pivoting part 61 of the rotating member 60 to be screwed together. It has a structure to be bonded.

At this time, the forming direction of the spiral thread (S ₁ , S ₂ ) also, when rotating in the reverse direction (counterclockwise) direction in which the rotating member 60 exits from the fixing member 50 side to compress the spring member 70 Is formed in, and when rotating in the forward direction (clockwise) is formed so that the rotating member 60 is inserted into the fixing member 50 inward direction to receive an elastic restoring force from the spring member 70.

In particular, the thread (S ₁ , S ₂ ) is formed spirally so as to have a sufficient pitch by forming a wide end of the thread (S ₁ , S ₂ ) that is not a pointed end of the thread used in the common screw It is preferable.

This is because when the hinge assembly H is mounted and used in the door 2 or the like, since the opening and closing distance of the door 2 is made within approximately 90 °, the rotation angle of the rotating member 60 is correspondingly 90 °. The reciprocating linear motion of the rotating member 60 is made in the state made within the bar, the rotating member 60 is a distance to sufficiently secure the elastic restoring force and the repulsive force of the spring member 70 according to the operation This is to give a sufficient pitch to the threads S1 and S2 so as to be movable.

Thus, the hinge assembly (H) of the present invention, even if the rotating part 61 of the rotating member 60 and the driven part 51 of the fixing member 50 is configured to operate by engaging with each other in the form of screw engagement door 2 It is obvious that can be opened and closed.

On the other hand, in the configuration of the hinge assembly (H) in accordance with the present invention, only the form in which one rotating member 60 is accommodated at one end of the fixing member 50 has been described.

However, a more preferred second embodiment of the hinge assembly (H ₂₎ of the hinge assembly (H) according to the present invention can take a structure expanding the first embodiment, the basic structure symmetrically.

That is, Figure 9 is an exploded perspective view showing a second embodiment of the hinge assembly according to the invention, Figure 10 is a combined perspective view of the hinge assembly according to the invention shown in Figure 9, Figure 11 is shown in Figure 9 Sectional view in the joined state of the hinge assembly according to the invention.

As shown in FIGS. 9 to 11, receiving grooves 52 are provided at both ends of the fixing member 50, and a driven part 51 is formed on the inner circumferential surface of each of the receiving grooves 52. The rotating part 61 and the spring member 70 provided with the pivoting part 61 in the driven part 51 have a structure in which they are symmetrically inserted into each other.

Of course, at this time, it is natural that the plurality of spring members 70 are designed to impart the elastic force of the same size at the left and right of the fixing member 50 while having the same spring elastic modulus.

In particular, by having such a structure, when the hinge assembly H ₂ shown in the second embodiment is mounted on the door 2 or the like rather than the hinge assembly H ₁ shown in the first embodiment, Since the plurality of rotating members 60 and the spring member 70 operate to alleviate the self-weight of the door 2 from the side or the structural side according to the operation, in one direction, one rotating member ( 60) and the spring member 70 will be more stable and more realistic structure than to relax in one direction.

At this time, the hinge assembly (H ₂ ) shown in the second embodiment is provided with a plurality of the rotation member 60 and the spring member 70 of the components of the hinge assembly (H ₁ ) shown in the first embodiment, respectively. The symmetrical structure of each of the left and right ends of the fixing member 50, the role and operation state of each component is the same as described in the first embodiment, and thus the details of each component Description is omitted.

On the other hand, in the case of the hinge assembly (H ₁ , H ₂ ) shown in the first embodiment and the second embodiment, the relative fastening portion to which the hinge assembly (H ₁ , H ₂ ) is fastened (for example, the door or Hinges (H ₁ , H ₂ ) are inserted into the separate receiving portions provided in the main body, so that the hinge assembly (H) shown in the first and second embodiments can be rotated only in a supported fixed state. ₁ , H ₂ ) has the constitutive features as a single unit itself with the conditions for rotation, but the hinge assembly (H ₁ , H ₂ ) itself can not operate alone relative to the door (2) and the body (1) Of course, the coupling with the separate receiving portion described later need of course.

13 and 14 illustrate a third embodiment of the hinge assembly H according to the present invention, which is different from the hinge assemblies H ₁ and H ₂ shown in the _first and _second embodiments. .

The hinge assembly receiving portion 4 is formed by forming the portion 6 and arranging the rotating member receiving portion 6 formed on each door 2 on both sides of the fixing member receiving portion 5. When the hinge assembly H ₂ according to the second embodiment is inserted and installed, the plurality of doors 2 may be installed to be opened and closed with one hinge assembly H ₂ .

Of course, at this time, the auxiliary support 7 is formed on both sides of the plurality of storage chambers corresponding to the fixed member accommodation part 5, and the rotation member is accommodated between the auxiliary support 7 and the fixed member accommodation part 5. The parts 6 are engaged with each other, and a fixed cap 8 is fitted between the auxiliary supporting part 7 and the rotating member accommodating part 6 so that both ends of the rotating member accommodating part 6 formed on the door 2 are respectively. By being supported and fixed by the rotating member 60 and the fixing cap 8, it is installed to prevent the departure of the door (2).

Meanwhile, the hinge assemblies H ₃ and H ₄ shown in the _third and fourth embodiments according to the present invention shown in FIGS. 12, 23 and 24 are disposed on the door 2 and the main body 1. The installation structure is very simple.

That is, the auxiliary fixing member 90 and the fixing member 50 are assembled so as to be in contact with each other, and then, through the flange portion (F ₂ ) of the auxiliary fixing member 90 to drive a fastener such as a screw body ( Fasten and assemble on either side of the back of 1) or the back of the door (2), and in response to the fitting fasteners such as screws through the flange portion (F ₁ ) of the fixing member 50 to the auxiliary fixing member (90) On the contrary, installation is completed by fastening and assembling the back of the main body 1 or the back of the door 2.

Of course, even in this case, when the hinge assembly (H ₃ , H ₄ ) is assembled after the opening portion on the auxiliary fixing member 90 and the fixing member, it is preferable to block the opening portion with the fixing cap (8). Do.

Looking at the operation and action of the hinge assembly (H) according to the present invention assembled through such an installation structure as follows.

First, FIGS. 21 to 24 show a hinge assembly having a plurality of rotating members installed on the rear surface of the kimchi storage when the door is opened and closed by applying the present invention, and FIGS. 21 and 22 illustrate a second embodiment of the present invention. 23 shows an operating state of the hinge assembly H ₂ , and FIGS. 23 and 24 show an operating state of the hinge assembly H ₄ according to the fourth embodiment of the present invention.

21 and 22, the fixing member accommodating part 5 of the hinge assembly accommodating part 4 is integrally formed on the main body 1, and the rotating member accommodating part of the hinge assembly accommodating part 4 is formed. For example, 6) is integrally formed on the rear surface of the door 2, and in FIGS. 23 and 24, the fixing member 50 is installed on the door 2 through the flange portion F ₁ , and the auxiliary fixing member It is exemplified that 90 is also installed on the body 1 via the flange portion F ₂ .

In particular, FIGS. 21 and 23 show that the rotating member 60 is pushed out of the fixing member 50 in the state in which the door 2 is closed, thereby maintaining the compressed form of the spring member 70 to have elastic restoring force. 22 and 24, the rotating member 60 is inserted into the fixing member 50 in the state in which the door 2 is opened, and thus the spring member 70 is elastically restored, and thus the initial state is not compressed and deformed. It shows how to keep the length.

That is, when the door 2 is opened, the door 2 is converted into the state shown in FIG. 22 from the state shown in FIG. 21 or the state shown in FIG. 24 from the state shown in FIG.

Here, the operation process of opening the door 2 will be described first.

First, in the case of FIGS. 21 and 22, since the rotating member accommodating part 6 is integrally formed on the door 2 side, the rotating member 60 of the hinge assembly H ₂ is positioned on the door 2 side. As a result, when the door 2 starts to open, the rotating member 60 is fitted through the fastening guide fixing part M ₁ formed in the rotating member accommodating part 6 of the door 2. When viewed from the front right side of the door 2 according to the opening angle of the door 2 is rotated in the forward direction (clockwise).

Accordingly, the fixing member 50 accommodated in the fixing member accommodating portion 5 of the main body 1 is the blood of the rotating part 61 and the fixing member 50 of the rotating member 60 while being fixed as it is. Due to the formation direction of the spiral inclined surfaces T ₁ and T ₂ or the spiral threads S ₁ and S ₂ formed in the eastern part 51, the rotating member 60 enters the inside of the fixing member 50.

That is, as the rotating member 60 rotates integrally with the rotating member accommodating part 6 according to the opening of the door 2, the fastening guide fixing part M ₁ is formed in the longitudinal direction in the rotating member accommodating part 6. Will be linear movement.

At this time, the spring member 70 is further promoted to be inserted into the fixing member 50 by pushing the rotating member 60 with the elastic restoring force at both ends while returning to the original state from the compressed state, as a result of the door (2) Help to open with little force.

That is, the user has an advantage that can easily open the door (2) even with a small force.

23 and 24, since the fixing member 50 is fastened to the door 2 through the plate-shaped flange portion F ₁ , when the door 2 starts to open, the fixing member 50 is fixed. The member 50 is rotated in the forward direction (clockwise) when viewed from the front right side of the door 2 according to the opening angle of the door 2.

Accordingly, the rotating member 60 coupled to the main body 1 through the auxiliary fixing member 90 is interlocked with the rotation of the fixing member 50 in a state in which the rotating member 60 is engaged with the fixing member 50.

That is, the formation direction of the spiral inclined surfaces (T ₁ , T ₂ ) or the spiral threads (S ₁ , S ₂ ) formed on the rotating part (61) of the rotating member (60) and the driven part (51) of the fixing member (50). Due to this, the rotating member 60 enters the inside of the fixing member 50.

Therefore, as the door 2 is opened, the rotating member 60 is linearly moved along the fastening portion N formed in the longitudinal direction in the auxiliary fixing member 90.

At this time, the spring member 70 is further promoted to be inserted into the fixing member 50 by pushing the rotating member 60 with the elastic restoring force at both ends while returning to the original state from the compressed state, as a result of the door (2) By assisting the opening of the) with a small force, the same effect as the opening operation of the hinge assembly (H ₂ ) through the hinge assembly receiving portion (4).

On the other hand, when the door 2 is closed, the operation of the hinge assembly (H ₄ ) occurs in the opposite direction to the opening process.

That is, when the door 2 starts to close, the rotating member 60 rotates in the reverse direction (counterclockwise) when viewed from the front right side of the door 2 according to the closing angle of the door 2. do.

Accordingly, the fixing member 50 accommodated in the fixing member accommodating portion 5 of the main body 1 is the blood of the rotating part 61 and the fixing member 50 of the rotating member 60 while being fixed as it is. Rotating member accommodating part while the rotating member 60 exits from the inside of the fixing member 50 due to the formation direction of the spiral inclined surfaces T ₁ , T ₂ or spiral threads S ₁ , S ₂ formed in the eastern part 51. Along the fastening guide fixing part (M ₁ ) formed in the longitudinal direction in (6) will be a linear movement.

At the same time, the spring member 70 is pushed to both sides to make it in a compressed state. As the spring member 70 is compressed, the elastic repulsive force of the spring member 70 is gradually increased and the weight of the door 2 descends. The closing speed of the door 2 is relaxed according to the force relationship.

Of course, in the hinge assembly (H ₄ ) consisting of the auxiliary fixing member 90 and the fixing member 50, as the fixing member 50 rotates in the reverse direction (counterclockwise) with the door 2, the fixing member The rotating member 60 engaged with the 50 is interlocked with each other, so that the helical inclined surfaces T ₁ , which are formed on the rotating part 61 of the rotating member 60 and the driven part 51 of the fixing member 50. T ₂ ) or the fastening part formed in the longitudinal direction on the inner circumferential surface of the auxiliary fixing member 90 while the rotating member 60 is pulled out from the inside of the fixing member 50 due to the forming direction of the spiral threads S ₁ and S ₂ . Linear movement along (N).

As the spring member 70 is compressed, the elastic repulsive force of the spring member 70 gradually increases, thereby reducing the closing speed of the door 2 according to the relationship between the weight and the force of the descending door 2. The same effect as the closing operation of the hinge assembly (H ₂ ) through the hinge assembly receiving portion (4).

In particular, when the door 2 is closed through the above operation, as described above, the driven member 51 of the rotating member 60, the rotating part 61 and the fixing member 50 is inclined surface (T ₁₎ , T ₂ ), and the door 2 has a predetermined height (upper surface of the storage chamber) when the predetermined gradient sections t ₁ and t ₂ are placed radially at the end portions of the inclined surfaces T ₁ and T ₂ . At about 5 to 10 °), the door 2 is rapidly closed due to its own weight as a result of the instantaneous increase in the weight of the door 2 relative to the elastic repulsive force of the spring member 70, and as a result, the door 2 ) Improves the hermeticity.

As such, when the hinge assembly H having various embodiments according to the present invention is used, when the door 2 is opened, the spring member 70 returns to the initial state while the elastic restoring force is applied to the door 2. Helps to facilitate the opening of the door 2, when closing the door 2, the spring member 70 is compressed and the elastic repulsive force acts to prevent the door 2 from being suddenly closed, and then set a predetermined height In the door 2 will be closed quickly only by the weight of itself.

As described above, according to the present invention, in the construction of a hinge assembly applied to a door of a kimchi storage, the rotating member converts the rotational movement into a linear movement according to the opening and closing of the door, and the rotating member is accommodated and supported by the rotating member. And a new hinge assembly composed of a fixed member operating in engagement with the rotating member, a spring member for imparting elastic restoring force and a repulsive force to the rotating member, and a fixed shaft for fixing and coupling the rotating member, thereby allowing forward, reverse and reciprocal linear motions of the rotating member. The elasticity of the spring member can be adjusted, and as a result, there is an effect that can reduce the opening and closing speed of the door using the hinge assembly.

In addition, the present invention in the installation of the hinge assembly to the door, etc., the insertion and insertion of the integral hinge assembly provided in the door and the main body or the hinge assembly itself can be detachably installed to open and close the door itself and the installation structure itself is very simple. While having an installation structure with excellent assembly properties, it is a very useful and preferred invention having the effect of reducing the opening and closing speed of the door to prevent shock and to secure the opening and closing of the door by a solid assembly.
