Description

Hinge module for revolving door {HINGE MODULE FOR ROTATING DOOR}

The present invention relates to a hinge module for a revolving door, and more particularly, to a hinge module for a revolving door that is mounted on a revolving door and can be opened and closed while the door rotates smoothly.

In general, a refrigerator is composed of a body for storing food and a door that opens and closes it.

When the door of the refrigerator is opened with a great force when the door is opened by external force, it may occur when it is hit by other objects and damaged.

In addition, when the refrigerator door is closed with a large force when the refrigerator door is closed by external force, a problem may occur due to a great impact on the main body of the refrigerator and impact on a container stored therein.

In order to solve this problem, in the related art, a damping force is generated when the refrigerator door is opened or closed, so that the door is opened slowly and closed slowly.

However, the conventional refrigerator door has the same damping force when opened and closed, and when the damping force is large, there is a problem that the refrigerator door is opened too slowly, and when the damping force is small, it opens when the refrigerator door is closed There was a problem in that the refrigerator body was shocked by being closed at the same speed.

In addition, when the refrigerator door is opened and many objects are inserted or removed inside the refrigerator, there is an inconvenience in that the door is automatically closed and the user has to insert or remove objects inside the refrigerator while holding the refrigerator door so as not to close.

Embodiment 1

The hinge module for a rotary door of the present invention, as shown in Figures 1 to 8, the housing 10, the shaft 20, the damper portion 30, the O-ring 40, and the support member 50 And, it comprises a torsion spring 60, the locking member 70 and the like.

In this embodiment, the housing 10 and the shaft 20 are rotated relative to the other one according to the mounting position, in this embodiment, the housing 10 is a shaft 20 as described later ) Will be explained on the premise of rotating.

In some cases, the housing 10 is fixed and the shaft 20 may be installed to rotate relative to the housing 10.

As illustrated in FIG. 1, in the present embodiment, the housing 10 is fixedly mounted to the rotating door 81, and the shaft 20 is a body object 82, a refrigerator, etc., to which the door 81 is hinged. ), The housing 10 rotates with respect to the shaft 20 when the door 81 rotates.

The housing 10 is formed in a hollow cylindrical shape, and is formed by communicating the first inner chamber 11 and the second inner chamber 12 therein, and the first inner chamber 11 is filled with oil.

In this embodiment, the housing 10 is composed of a first housing 10a in which the first inner chamber 11 is formed, and a second housing 10b in which the second inner chamber 12 is formed in the interior. The first housing 10a and the second housing 10b are screwed together.

As illustrated in FIG. 8, an engaging groove 14 is formed on the inside of the housing 10 to selectively engage the engaging member 70.

The locking groove 14 may be formed to be directly concave on the inner circumferential surface of the housing 10, or may be formed by combining a separate member inside the housing 10, but all of the locking grooves 14 are It is the same as that formed on the inner circumferential surface of the housing 10.

That is, the locking groove 14 may be integrally formed with the housing 10 or a separate member may be combined with the housing 10.

In this embodiment, it will be described on the premise that the locking groove 14 is formed directly on the housing 10.

The details of the locking groove 14 will be described together when the locking member 70 is described.

The shaft 20 is rotatably mounted to the housing 10 while passing through the first inner chamber 11 as shown in FIGS. 3 and 6.

One end of the shaft 20 is exposed to the outside of one end of the housing 10, and the other end is disposed in the second inner chamber 12.

The outer circumferential surface of the shaft 20 inserted into the first inner chamber 11 is spaced apart from the inner circumferential surface of the first inner chamber 11 and the oil is filled therebetween.

The damper unit 30 is mounted on the first inner chamber 11 and controls the amount of oil filled in the first inner chamber 11 when the housing 10 and the shaft 20 are relatively rotated.

That is, the damper unit 30 adjusts the amount of oil filled in the first inner chamber 11 when the housing 10 is rotated with respect to the shaft 20.

More specifically, the amount of oil is changed by the damper part 30 in the process of rotating the housing 10 relative to the shaft 20, thereby rotating the housing 10 relative to the shaft 20 The speed will vary depending on the rotation section and / or direction of rotation.

The damper part 30 is made of a blocking member 31 and a blade 32.

The blocking member 31 is made of a synthetic resin, rubber, silicone, or the like, and is disposed between the inner circumferential surface of the first inner chamber 11 and the outer circumferential surface of the shaft 20.

The blocking member 31 has one end fixedly coupled to the inner circumferential surface of the first inner chamber 11, and the other end is in contact with the outer circumferential surface of the shaft 20 to block the oil in the first inner chamber 11 Prevent movement across the member (31).

Therefore, when the housing 10 is rotated, the blocking member 31 is rotated together with the housing 10, whereby the oil filled in the first inner chamber 11 is transferred to the blocking member 31. It is pushed and moved to generate hydraulic pressure.

On both sides of the blocking member 31, a wing portion 31a having a concave center is formed.

During the relative rotation of the housing 10 and the shaft 20, the wing portion 31a is unfolded by the hydraulic pressure generated by the oil filled in the first inner chamber 11 while the first inner chamber 11 is unfolded. By being in close contact with the inner circumferential surface and the outer circumferential surface of the shaft 20, it is possible to more effectively block oil from moving across the blocking member 31.

The blade 32 is formed in a rod shape and is disposed between the shaft 20 and the inner circumferential surface of the first inner chamber 11.

When the housing 10 and the shaft 20 are relatively rotated, the blocking member 31 moves together with the housing 10, and the blade 32 is in contact with the inner circumferential surface of the first inner chamber 11. It moves together with the shaft (20).

When the housing 10 is rotated, the blocking member 31 is rotated together with the housing 10, the blade 32 is in contact with the inner circumferential surface of the first inner chamber 11 shaft 20 Is located with

On the outer circumferential surface of the shaft 20, a concave seating groove 21 is formed long along the longitudinal direction of the shaft 20, and the blade 32 of a cylindrical shape is seated on the seating groove 21.

At this time, the curvature of the seating groove 21 is formed to be larger than the curvature of the blade 32, so that when the relative rotation of the housing 10 and the shaft 20, the blade 32 is inside the seating groove 21 So you can move a little bit

More specifically, the blade 32 is in contact with both the seating groove 21 and the inner circumferential surface of the first inner chamber 11, the housing 10 is pushed by the blocking member 31 when rotating The blade 32 is slightly moved by the oil in the seating groove 21.

Then, the blade 32 changes the amount of movement of the oil filled in the first inner chamber 11 when the housing 10 and the shaft 20 are rotated relative to each other.

To this end, as shown in FIGS. 4, 6, and 7, the first flow path 13 is formed in a concave groove shape along the circumferential direction of the housing 10 on the inner circumferential surface of the first inner chamber 11.

The first flow path 13 is composed of a first-first flow path 13a and a first-second flow path 13b, and the first-first flow path 13a and a first-second flow path 13b are the housings. It is spaced along the circumferential direction of (10).

When the housing 10 is rotated, the blade 32 has an outer circumferential surface contacting an inner circumferential surface of the first inner chamber 11 of a portion without the first flow path 13 and a portion where the first flow path 13 is formed. .

That is, as the housing 10 rotates, the first flow path 13 also moves, while the first-first flow path 13a and the first-second flow path 13b contact the blade 32 or Or you don't come across.

10 and 12, when the blade 32 is disposed in a portion where the first-first flow path 13a and the first-second flow path 13b are formed, the oil is the first-first flow. It moves in the opposite direction of the blade 32 through the flow path 13a or the 1-2 flow path 13b.

Therefore, when the blade 32 is disposed in a portion without the first-first flow path 13a and the first-second flow path 13b when the housing 10 is rotated, the movement of the oil is not easily performed. When the housing 10 is rotated somewhat slowly, and the blade 32 is disposed in a portion where the first-first flow path 13a and the first-second flow path 13b are present, the first-first of the oil. By moving through the 1 flow path 13a and the 1-2 flow path 13b, the housing 10 is rotated more quickly.

In addition, a second flow path 23 communicating with the seating groove 21 on one side of the seating groove 21 is formed on the outer circumferential surface of the shaft 20 more concave than the seating groove 21.

When the blade 32 moves from one side to the other side of the seating groove 21 in the seating groove 21 by the rotation of the housing 10, the seating groove by the movement of the blade 32 ( 21) and the size of the second flow path 23 communicating with each other is variable or opened and closed.

The portion where the second flow path 23 is formed in the seating groove 21 is referred to as one side of the seating groove 21, and the opposite direction of the second flow path 23, that is, the second flow path 23 is not formed. The part that is not is called the other side of the seating groove 21.

Specifically, as shown in Figure 10, when the blade 32 is moved to one side of the seating groove 21 in the direction in which the second flow path 23 is formed, the seating groove 21 is the blade ( While communicating with the second flow path 23 disposed at the bottom of 32), the second flow path 23 communicates with the opposite direction of the blade 32.

And, as shown in Figure 12, when the blade 32 is moved to the other side of the seating groove 21 in the opposite direction of the second flow path 23, the seating groove 21 is the blade 32 ), The communication with the second flow path 23 is blocked.

Here, 'blocking' may mean that the blade 32 completely closes the seating groove 21 and the second flow path 23, and the blade 32 is the seating groove 21. Moving to one side of the seating groove 21 and the second flow path 23 may mean that the communication area is less than when the communication.

That is, when the blade 32 blocks the communication between the second flow path 23 and the seating groove 21, the blade 32 moves to one side of the seating groove 21, so that the seating groove 21 ) And the second flow path 23 means that the area to be communicated is smaller than when it was communicated.

By the rotation of the housing 10, the blade 32 in the seating groove 21 moves to one side of the seating groove 21 so that the seating groove 21 passes through the second flow path 23. When the communication with the opposite direction of the blade 32, the blade 32 moves to the other side of the seating groove 21, the oil than when the communication between the seating groove 21 and the second flow path 23 is blocked Will increase the amount of movement.

That is, when the blade 32 is moved to the other side of the seating groove 21 in the opposite direction of the second flow path 23, the inner peripheral surface of the first chamber 11 by the blade 32 and the The gap between the seating grooves 21 is almost closed, so that the amount of oil is less moved.

Then, when the blade 32 is moved to one side of the seating groove 21 in the direction of the second channel 23, the second channel 23 located at the lower portion of the blade 32 is seated While communicating with the groove 21, the amount of oil movement increases through this passage.

Either one of the housing 10 or the shaft 20 is mounted on the rotating door 81 and rotates together with the door 81.

In this embodiment, the housing 10 is mounted on the rotating door 81, so that when the door 81 is rotated, the housing 10 is rotated together.

Due to the rotation of the housing 10, the oil filled in the first interior chamber 11 moves, whereby the blade 32 moves within the seating groove 21. When rotating in the open direction from the closed state, the second flow path 23 is in communication with the opposite direction of the blade 32 through the seating groove 21 by the movement of the blade 32.

Due to this, when the door 81 is rotated in the open direction in the closed state, the amount of oil movement increases when the door 81 is rotated in the closed direction in the open state, and when the door 81 is opened The door 81 rotates faster than when it is closed.

In addition, a third flow path 24 is formed through the shaft 20 in a direction perpendicular to the longitudinal direction.

The oil filled in the first inner chamber 11 moves in opposite directions through the third flow path 24 when the housing 10 and the shaft 20 are rotated.

In addition, an adjustment screw 26 is mounted at one end of the shaft 20 to adjust the size of the third flow path 24.

The end of the adjustment screw 26 is inserted between one end and the other end of the third flow path 24, and one end of the third flow path 24 by rotating the adjustment screw 26 relative to the shaft 20 You can adjust the communication area of the other end.

As described above, by adjusting the adjustment screw 26 to control the amount of oil movement through the third flow path 24, the damping force during rotation of the housing 10 can be adjusted, and finally the door 81 Rotation speed can be controlled.

The O-ring 40 is coupled to the shaft 20 and blocks the first inner chamber 11 and the second inner chamber 12 in contact with the housing 10.

The O-ring 40 is mounted in a different position to prevent the oil filled in the first interior chamber 11 from flowing out.

The support member 50 is mounted on the other end of the housing 10 to block the second inner chamber 12.

More specifically, the support member 50 is mounted on the other end of the second housing 10b, thereby blocking the second inner chamber 12 formed inside the second housing 10b.

The torsion spring 60 is disposed inside the second inner chamber 12, one end is coupled to the other end of the shaft 20 and the other end is coupled to the support member 50.

The torsion spring 60 may adjust the elastic force according to the angle at which the support member 50 is mounted on the other end of the housing 10.

The torsion spring 60 is elastically deformed when either one of the housing 10 or the shaft 20 is rotated.

In this embodiment, since the housing 10 rotates, when the housing 10 rotates, the support member 50 coupled to the other end of the housing 10 rotates, and the torsion spring 60 The other end of the coupling to the support member 50 and one end of the torsion spring 60 is coupled to the shaft 20, the housing 10 and the support member 50 when rotating the torsion spring 60 is elastically deformed while the other end rotates with respect to one end.

The locking member 70 is coupled to the other end of the shaft 20 and relatively rotates with the shaft 20 with respect to the housing 10.

In this embodiment, since the shaft 20 is fixed and the housing 10 rotates, when the housing 10 is rotated, the locking member 70 does not rotate with the housing 10, but the It remains fixed with the shaft 20.

The locking member 70 is hung on the locking groove 14 formed on the inner circumferential surface of the housing 10 when either one of the housing 10 or the shaft 20 rotates, so that the housing 10 or the shaft ( 20) The rotation is temporarily stopped.

In order to engage the locking member 70 at the other end of the shaft 20, a pair of fixing protrusions 25 are spaced apart from each other at the other end of the shaft 20, parallel to the longitudinal direction of the shaft 20 It is formed to protrude, the engaging member 70 is coupled to the fixed projection (25).

Then, one end of the torsion spring 60 is coupled to the fixed protrusion 25 in a state where the engaging member 70 is coupled to the fixed protrusion 25.

Since the locking groove 14 is formed in the housing 10 and the locking member 70 is coupled to the shaft 20, when the housing 10 and the shaft 20 are relatively rotated, The engaging groove 14 and the engaging member 70 are also rotated relative to each other.

When the housing 10 is rotated with respect to the shaft 20 by external force, the torsion spring 60 is elastically deformed, and when removed by external force, the torsion spring 60 is opened by the elastic restoring force. It will rotate to its original position.

In the following description, the first angle and the second angle do not only mean a specific angle shown in the drawing, but the angle may be changed according to environment and conditions.

10 (a) to 10 (c), the housing 10 is rotated by an external force to less than a first predetermined angle (eg, about 90 degrees) with respect to the shaft 20. In the state, the locking member 70 is not caught in the locking groove 14, and when the external force is removed, the housing 10 is rotated relative to the shaft 20 by the elastic restoring force of the torsion spring 60 to return to its original position. To return

And, as shown in Figure 10 (d), when the housing 10 is rotated to the first angle (for example, about 90 degrees) with respect to the shaft 20 by external force, the locking member ( Even if the elastic restoring force of the torsion spring 60 occurs while the 70 is caught in the locking groove 14 and the elastic force of the torsion spring 60 is generated, the housing 10 does not rotate with respect to the shaft 20 and maintains the state.

In addition, in the state in which the locking member 70 is caught in the locking groove 14, as shown in FIG. 12, the housing 10 by the external force passes the first angle to a second predetermined angle (for example, For example, when rotated to about 100 degrees), the locking member 70 is released from the locking groove 14, and when the external force is removed, the housing 10 by the elastic restoring force of the torsion spring 60 Is rotated with respect to the shaft 20 to return to the original position.

That is, when the housing 10 is rotated below the first angle, when the external force is removed, it returns to its original position by the torsion spring 60, and when the first angle is reached, the locking member 70 is The housing 10 is caught in the locking groove 14 and maintains the rotated state, and when the housing 10 is rotated to a second angle after passing through the first angle, the locking member 70 causes the locking groove ( 14) As the jammed state is released, the housing 10 is rotated to the original position and returned by the elastic restoring force of the torsion spring 60.

In order to make this operation process, the locking member 70 includes a locking body 71, a locking protrusion 72, and a locking elastic body 73, as shown in FIGS. 5 and 8.

The engaging body 71 is coupled with two plates spaced apart from each other, and coupled to the other end of the shaft 20.

One end of the locking protrusion 72 is rotatably mounted to the locking body 71, and the other end protrudes outwardly of the locking body 71.

More specifically, one end of the locking protrusion 72 is hinged to the locking body 71 rotatably inside the locking body 71 made of two plates.

The locking projections 72 may be made of only one, but it is preferable to be made of a pair arranged in opposite directions based on the locking body 71 as in the present embodiment.

The engaging elastic body 73 is coupled to the engaging projection 72 and adds an elastic force so that the engaging projection 72 is rotated to its original position when external force is removed.

The engaging elastic body 73 may have one end coupled to the engaging protrusion 72 and the other end coupled to the engaging body 71, but when the engaging protrusion 72 is made of a pair, as in the present embodiment The engaging elastic body 73 is preferably to connect one end of the pair of engaging projections 72 to each other.

And, as shown in Figure 8, the first circumferential groove on the inner circumferential surface of the housing 10, the other end of the locking protrusion 72 is disposed when the housing 10 and the shaft 20 are rotated or stopped. 15 and the second arrangement groove 16 are formed spaced apart from each other.

Between the first arrangement groove 15 and the second arrangement groove 16, when the relative rotation of the housing 10 and the shaft 20 is pressed, the other end of the locking protrusion 72 is pressed so that the locking protrusion 72 is The pressing jaw 17 is rotated in the direction of the locking body 71 is protruded.

Between the second placement groove 16 and the pressing jaw 17, the locking groove 14 having a smaller depth than the second placement groove 16 is formed.

Due to the shape of the inner circumferential surfaces of the locking member 70 and the housing 10, as shown in FIG. 11 (a), the housing 10 is not rotated with respect to the shaft 20, that is, external force is not applied. In the free state, the other end of the locking protrusion 72 is disposed in the first placement groove 15.

As shown in FIGS. 11 (b) to 11 (c) by external force, when the housing 10 rotates below a predetermined first angle with respect to the shaft 20, the locking protrusion 72 rotates The locking elastic body 73 is pressed while elastically deformed by the pressing jaw 17, and when the external force is removed, the housing 10 is rotated to its original position by the elastic restoring force of the torsion spring 60, so that the locking protrusion ( 72) is rotated in the original state by the engaging elastic body 73 is disposed in the first arrangement groove (15) again.

When the housing 10 is rotated to the first angle with respect to the shaft 20 as shown in FIG. 11 (d), the locking protrusion 72 passes through the pressing jaw 17 and then the locking While rotating by the elastic restoring force of the elastic body 73, the other end is caught in the engaging groove 14, thereby removing the external force so that even if the elastic restoring force of the torsion spring 60 is activated, the housing 10 remains on the shaft ( 20) will remain in the rotated state.

And, as shown in Figure 13 (a), when the housing 10 is rotated to a predetermined second angle past the first angle, the other end of the locking protrusion 72 is in the locking groove (14) As being detached, the locking protrusion 72 is rotated to the original position in the second placement groove 16 by the elastic restoring force of the locking elastic body 73, as shown in FIGS. 13 (b) to (e) when removing external force. Likewise, the housing 10 is rotated to the original position with respect to the shaft 20 by the elastic restoring force of the torsion spring 60, so that the locking protrusion 72 presses the locking jaw in the second placement groove 16 It passes through the chin 17 and is disposed in the first arrangement groove 15 again.

At this time, when the housing 10 is rotated by the torsion spring 60, the engaging projection 72 is rotated in the opposite direction of the engaging groove 14 while contacting the pressing jaw 17 The locking protrusion 72 will not be caught in the locking groove 14.

The hinge module of the present invention as described above is coupled to the door 81 and the body object 82, in this embodiment the housing 10 is fixedly mounted to the rotating door 81, the shaft 20 is the The door 81 is hingedly coupled to the main body object 82, and when the door 81 rotates, the housing 10 rotates relative to the shaft 20, so that the torsion spring 60 is elastically deformed. .

9 illustrates a process in which the door 81 is rotated to open or close by being mounted on the door 81 to the hinge module of the present invention.

And Figure 10 shows the operating process of the damper unit 30 in the state where the door 81 is opened, Figure 11 shows the operating process of the locking member 70 in the state where the door 81 is opened , FIG. 12 shows the operation process of the damper unit 30 in the state where the door 81 is closed, and FIG. 13 shows the operation process of the locking member 70 in the state where the door 81 is closed. .

When the door 81 is closed, it is as shown in FIGS. 10 (a) and 11 (a).

When the door 81 starts to be opened by external force, the housing 10 and the blocking member 31 rotate as shown in FIGS. 10 and 11.

When the door 81 is opened below a preset first angle (about 90 degrees), as shown in FIGS. 11 (b) and (c), the locking protrusion 72 is the locking groove 14 Since the external force is removed, the door 81 is closed by rotating to the original position by the elastic restoring force of the torsion spring 60.

At this time, as shown in FIG. 10, the blade 32 is moved by the movement of oil filled in the first inner chamber 11 as the housing 10 and the blocking member 31 rotate clockwise. The second flow path 23 is opened while moving.

In addition, when the section in which the first-first flow path 13a is formed by the normal rotation of the housing 10 is in contact with the blade 32, the oil is also moved through the first-first flow path 13a.

Accordingly, when the door 81 mounted on the housing 10 is rotated, the oil filled in the first interior chamber 11 is rotated through the first-first flow path 13a, the second flow path 23, and the third flow path. Since (24) is moved, as described later, the door 81 is rotated and opened more quickly than when it is closed.

When the door 81 is opened at a predetermined first angle (about 90 degrees), as shown in FIG. 11 (d), when the external force is removed, the locking protrusion 72 is caught in the locking groove 14 The rotation of the door 81 is temporarily stopped.

In other words, when the door 81 is rotated, the housing 10 is rotated to elastically deform the torsion spring 60 so that an external force machine, the elastic restoration force of the torsion spring 60, acts, but the locking protrusion 72 ) Is caught in the locking groove 14 and the door 81 is not rotated in the closing direction and stops in an open state.

Through this, the door 81 of the refrigerator or the like can be kept open, so that when a user inserts or removes an object in the refrigerator, the user can conveniently insert or remove the object without interfering with the door 81.

In the drawing, although the first angle is illustrated at 90 degrees, the first angle may be set to an angle of 90 degrees or less or more than 90 degrees depending on the formation position of the locking groove 14.

When the door 81 is to be closed while the door 81 is stopped in an open state, as shown in FIG. 9, the door 81 is rotated about 10 degrees further in the opening direction and then external force is applied. Remove it.

When the door 81 is rotated to open a predetermined second angle (about 100 degrees) after passing through the first angle (about 90 degrees), the housing 10 is shown in FIGS. 12 (a) and 13 (a). It will rotate as shown in.

At this time, as shown in Figure 13 (a), the locking protrusion 72 is released from the locking groove (14).

Then, when the external force is removed, as shown in FIGS. 12 and 13, the housing 10 is rotated to the original position by the elastic restoring force of the torsion spring 60, thereby coupling to the housing 10 The door 81 is automatically closed.

At this time, as shown in Figure 12 (b) to (f), when the housing 10 is reversely rotated in the direction in which the door 81 is closed, the movement of the oil filled in the first inner chamber 11 is caused. By this, the blade 32 moves in a direction blocking the second flow path 23 to block the second flow path 23.

Therefore, as shown in FIGS. 12 (b) to 12 (f), in the process of closing the door 81, the first-to-first passage 13a, the first-second passage 13b, and the third passage 24 Since the oil is moved, the amount of oil movement is less than the process in which the door 81 is opened, so that it is closed slightly slower than when the door 81 is opened.

And, as shown in Figure 12 (e), the housing 10 is rotated in reverse, so that the blade 32 is disposed between the 1-1 flow path 13a and the 1-2 flow path 13b When the oil cannot move through the first flow paths 13a and 13b, the housing 10 and the door 81 rotate relatively slowly.

Then, as shown in FIG. 12 (f), when the door 81 is almost closed by the reverse rotation of the housing 10, the blade 32 is formed with the 1-2 flow path 13b. Being disposed at the site, the oil is additionally moved through the 1-2 passage 13b, so that the housing 10 and the door 18 are rapidly rotated and closed.

Therefore, the door 81 is closed by rotating relatively quickly at first during the closing process, but near the end, the door 81 is slowly rotated to close smoothly, and finally, by turning quickly and strongly again, the door 18 is accurately It closes well.

As described above, by the rotation of the housing 10 while the door 81 is rotated, the amount of oil movement through the second flow path 23 is variable, and when the door 81 is opened, it opens quickly. When the door 81 is closed, it can be closed slowly and then closed quickly in the last section.

In addition, when the housing 10 rotates, the door 81 is in a section in contact with the blade 32 and the portion where the first flow path 13 is formed by the amount of oil movement through the first flow path 13. Is rotated quickly, but the door 81 is slowly rotated in a section where the first flow path 13 is not in contact with the blade 32.

Therefore, when opening the door 81, the door 81 can be opened relatively faster than when closing, and in the process of opening and closing the door 81, the first-first flow paths 13a and 1-2-path 13b In the section where) is formed, the door 81 rotates quickly, but in the section without the first-first flow path 13a and the first-second flow path 13b, the door 81 is smoothly and accurately closed while rotating slowly. As the door 81 is closed, it is possible to accurately close it while minimizing the impact applied to the body object 82.

In addition, as described above, it is possible to keep the door 81 open, and it is easy to insert and remove objects or the like inside the body object 82.

In some cases, the first and second flow paths 13b may not exist.

The hinge module for the revolving door 81 of the present invention as described above can be applied to a washing machine, a styler, a glass door, a visitor, etc., in which the door 81 is rotated.

Example 2

14 is a perspective view of a blade and a shaft according to a second embodiment of the present invention, and FIG. 15 is a cross-sectional view showing the operating relationship of a blade and a shaft according to the second embodiment of the present invention.

The second embodiment differs from the first embodiment in that the permanent magnet 35 is mounted inside the blade 32.

In the second embodiment, the shaft 20 and the blade 32 are made of a magnetic material such as iron.

In addition, a permanent magnet 35 is mounted inside the blade 32.

Accordingly, the blade 32 made of a magnetic body is magnetized entirely by a permanent magnet 35 mounted therein.

When the blade 32 is seated in the seating groove 21, a magnetic force is generated between the blade 32 and the shaft 20 by the permanent magnet 35 mounted inside the blade 32. do.

When comparing the strength of the magnetic force, the strength of the magnetic force between the other side 21b of the seating groove without the second flow path 23 and the blade 32 is that of the seating groove in which the second flow path 23 is formed. It is greater than the strength of the magnetic force between one side (21a) and the blade (32).

If the second flow path 23 is not formed in the seating groove 21, the strength of the magnetic force between the blade 32 and one side 21a and the other side 21b of the seating groove is the same.

However, since the second flow path 23 is formed on one side 21a of the seating groove, the magnetic force area facing the blade 32 and one side 21a of the seating groove is the blade 32. And the other side (21b) of the seating groove is less than the magnetic force area facing, the strength of the magnetic force between the blade (32) and the other side (21b) of the seating groove is the blade 32 and one side (21a) of the seating groove ) Becomes greater than the strength of the magnetic force.

Therefore, as shown in FIG. 15 (a), in a free state in which no external force is applied, the blade 32 by the magnetic force area between the blade 32 and the shaft 20 has a large magnetic area. It moves to the other side (21b) of the groove and closes the seating groove (21) while blocking the communication between the seating groove (21) and the second flow path (23).

Then, by the pressure of the oil generated when the oil moves due to the relative rotation of the housing and the shaft 20, as shown in Figure 15 (b) and (c), the blade 32 is the seating groove While being separated from the other side (21b) to move to one side (21a) of the seating groove to communicate with the seating groove 21 and the second flow path (23).

When the pressure of the oil disappears in this state, as shown in FIG. 15 (d), the blade 32 is again seated by the magnetic force between the blade 32 and the other side 21b of the seating groove. It moves to the other side (21b) of the groove to block the communication between the seating groove 21 and the second flow path (23).

By attaching a permanent magnet 35 to the blade 32 as above, the blade 32 blocks the communication between the seating groove 21 and the second flow path 23 in a free state, thereby reducing the amount of oil movement. By doing so, it is possible to prevent the door on which the housing 10 is mounted from rotating arbitrarily and easily.

Other details are the same as those of the first embodiment, so a detailed description thereof will be omitted.

The third embodiment has a difference in that the elastic member 19 is added as compared to the first embodiment, and this will be mainly described.

In the third embodiment, the elastic member 19 is coupled to the inside of the first inner chamber 11 in detail inside the housing 10 to rotate together with the housing 10.

The elastic member 19 is formed with a locking groove 14 through which the locking member 70 is selectively caught.

When the rotation of any one of the housing 10 or the shaft 20, the torsion spring 60 is elastically deformed, and the engaging member 70 is hung in the engaging groove 14 formed in the elastic member 19 The rotation of the housing 10 or the shaft 20 is temporarily stopped.

By the rotation of the housing 10 by external force, the locking member 70 is released from the locking groove 14, and when the external force is removed, the housing 10 by the elastic restoring force of the torsion spring 60 Is rotated to the original position with respect to the shaft 20.

18 to 20, the housing 10 is rotated clockwise in the forward direction, and the housing 10 is rotated counterclockwise in the reverse direction.

18, when the housing 10 rotates in the forward direction, the elastic member 19 coupled to the housing 10 also rotates in the forward direction, and when rotated to the first angle, As shown in 18 (c), the locking protrusion 72 is caught in the locking groove 14 to maintain the state in which the housing 10 is stopped.

As described above, in a state where the rotation of the housing 10 is stopped, there are two methods shown in FIGS. 19 and 20 for rotating the housing 10 to the original position.

19 is the same as the first embodiment described above.

That is, as shown in FIG. 19 (a), the housing 10 is rotated forward through the first angle to the second angle so that the locking protrusion 72 is separated from the locking groove 14, thereby As shown in 19 (b) and (c), the housing 10 is reversely rotated by the elastic restoring force of the torsion spring 60 to be rotated to its original position.

At this time, the elastic member 19 is also provided with the first placement groove 15 and the second placement groove 16, so that the locking projections 72 from the locking groove 14 as in the first embodiment You can let it escape.

FIG. 20 shows a method of rotating the housing 10 in a reverse position to rotate it to its original position, unlike the first embodiment. As shown in FIG. 18 (c), the housing 10 is stopped. In, if the external force is applied in the reverse rotation direction without directly rotating the housing 10, the housing 10 may rotate to its original position.

More specifically, as shown in FIG. 18 (c), the housing 10 is rotated to rotate the housing 10 in its original position while the locking member 70 is caught in the locking groove 14 When a strong external force acts in the reverse direction, as shown in FIG. 20 (a), the elastic member 19 in contact with the locking protrusion 72 is elastically deformed while the locking protrusion 72 is the elastic member 19 The housing 10 is separated from the locking groove 14 formed in the housing 10 by the elastic restoring force of the torsion spring 60, as shown in FIGS. 20 (b) and (c). Is rotated to the original position.

That is, the elastic member 19 in contact with the locking protrusion 72 is elastically deformed by an external force to change its diameter or shape, and at this time, the locking protrusion 72 is in its original state by the elastic restoring force of the locking elastic body 73. Rotated to a position, the other end of the locking projection 72 is released from the locking groove 14 formed in the elastic member 19.

As described above, when the locking protrusion 72 is separated from the locking groove 14 formed in the elastic member 19, the housing 10 is rotated to the original position by the elastic restoring force of the torsion spring 60.

Therefore, in the third embodiment, there are two methods of rotating the housing 10, which is stopped by normal rotation, so as to be disposed in the original position, which operates according to a user's needs or environment.

That is, when the housing 10 is mounted on a rotating door 81 on which the housing 10 is mounted, and the door 81 is opened to a first angle, when the user wants to close the door 81, the user The door 81 may be closed after further rotation, or the door 81 may be closed by pushing the door 81 counterclockwise.
