According to the fourth embodiment of the present invention shown in FIG. 13, when the magnetic hinge is applied to cover hinges installed on various covers (kimchi refrigerators, notebook computers, mobile phones, copiers, fax machines, etc.), the magnetic hinge is formed in a cylindrical shape. Among the parts where the body rear end and the cover are connected, a housing 100 is disposed in a horizontal direction in the cover (or body rear end), and bearing grooves 102 are formed at both ends in the housing 100, respectively. Bearings 60 are respectively coupled to the bearing grooves 102, and magnet grooves 103 are formed in parallel with the two bearings 60, respectively, and are horizontally coupled to the housing 100 and fixed to the center portion thereof. A deeply cut magnet fixing groove 32 is formed, and one end portion (or both ends) is formed to include a hinge shaft 30 protruding out of the housing 100 and coupled to the body rear end portion (or cover). .

The magnet fixing groove 32 formed at the center of the hinge shaft 30 is cut by a depth of 1 to 2 millimeters [mm] in the same width as the thickness of the angle adjusting magnet 70 and is an inner part of the angle adjusting magnet 70. Is embedded and coupled to the state in which the ring-shaped rotating support 120 is fitted to the angle adjustment magnet 70 outside.

Two magnet grooves 103 and two inner ring-shaped magnets in the rotary support 120 are divided into two, and the adjacent magnets are coupled to each other by the magnetic force of the angle adjusting magnets having different magnetic poles arranged on the upper surface thereof.

Referring to the accompanying drawings, the operation of the present invention configured as described above is as follows.

First, the angle adjusting magnet 70 to play a key role in the present invention will be described.

One of the characteristics of magnets is that the strongest magnetic force in a magnet with constant size is from the tip to the constant part, including the tip, so that the attraction force is strong when two strong magnets are attached with different polarities (N pole and S pole). But even with little force, the two magnets easily move a little while attached.

This means that it is difficult to use magnetic force where it requires precise operation.

Therefore, in the present invention, a pair of magnets, which are divided into ring-shaped magnets, is arranged up and down in the state of being fitted to the hinge shaft so that the attraction force and the repulsive force can act simultaneously to control rotation and stop at the correct angle. The feature is that it is possible.

The angle adjusting magnet 70 used in the magnet hinge according to the present invention divides the ring-shaped magnet into 2 equal parts to 4 equal parts to 6 equal parts so that adjacent magnetic poles (N pole and S pole) are arranged differently from each other.

At this time, since the angle is automatically determined when the door is opened or closed depending on how much the ring-shaped magnet is divided, it is defined as the angle adjustment magnet (70).

1A and 1B, when the angle adjustment magnet 70 is divided into four, the same magnetic poles are completely overlapped as shown in FIG. 1B, and the repulsive force is the strongest, and different magnetic poles are stacked as shown in FIG. 1A. Ground attraction is the strongest.

Therefore, the pair of angle adjustment magnets 70 are rotated from FIG. 1B to FIG. 1A based on the hinge axis 30 by the attraction force and the repulsive force generated between the pair of angle adjustment magnets 70. .

At this time, from 1b to 1a automatically rotate left or right by an angle of exactly 90 °.

Therefore, the angle-adjusting magnet 70 divided into four ring-type magnets is applied to the door that opens the door at 180 ° or less. When the door is opened at 90 ° or less, the door is automatically closed. When the door is opened at 90 ° or more, the angle is automatically 180. Open to ° to remain open.

In addition, when the angle adjusting magnet 70 is divided into two, it is automatically rotated by an angle of exactly 180 ° to the left or right.

Therefore, the angle-adjusting magnet 70 divided into two ring-type magnets is applied to the door that opens the door at 180 ° or less, and the door is automatically closed when the door is opened at 180 ° or less.

In particular, when the ring-shaped angle adjustment magnet 70 is divided into two, when the door is closed at -5 ° when the attraction force is strongest between the pair of angle adjustment magnets 70, the door is automatically opened below 175 °. If it closes and opens more than 175 °, it automatically opens to 180 ° and stays open.

In addition, when the angle adjustment magnet 70 is divided into six equally, it is automatically rotated by an angle of 60 ° to the left or right.

Therefore, the angle-adjusting magnet 70 divided into six ring-shaped magnets is generally applied to a door that opens the door at 120 ° or less. When the door is opened at 60 ° or less, the door is automatically closed. It opens at 120 ° and keeps it open.

In particular, the ring-shaped magnet 6 divided into six angle adjustment magnet 70 may be applied to a special place, such as a refrigerator door, when the repulsive force is the strongest between the pair of angle adjustment magnet 70 is opened to approximately 30 ° If the door is set to 30 ° or less, the door closes automatically. If the door is opened more than 30 °, the door is automatically opened to 90 ° to maintain the open state.

On the other hand, the relationship between the attraction force and the repulsive force generated between the pair of angle adjustment magnets 70 is generated only when the attraction force when arranged as shown in FIG. At any position between 1b, the strength of the repulsive force (or attractive force) is further generated by the decreasing intensity of the attractive force (or repulsive force).

That is, the rotational force generated between the pair of angle adjusting magnets 70 is always generated in a constant size regardless of the position of the pair of angle adjusting magnets 70.

Thus, in a door to which the magnet hinge is applied, the door is closed (or opened) at a constant rotational force whenever the door is automatically closed (or automatically opened).

The constant rotational force generated between the pair of angle adjustment magnets 70 not only serves to close the door, but also replaces the hydraulic device for closing the door at a constant speed in the existing door closer or floor hinge.

In addition, all conventional door closers or floor hinges using hydraulic pressure have a disadvantage in that the rotational force for closing the door immediately before the door is closed is reduced, but the magnet hinge of the present invention can overcome this disadvantage.

8 to 9 to 10, when the magnetic hinge is applied to the armless door closer, three angle adjustment magnets 70 (inside the moving support 80, the rotation support 120, the magnet groove) (103), as described above, each of the angle adjusting magnets 70 is divided into two to four equal parts of the ring-shaped magnets, the neighboring magnets are arranged differently and the magnetic poles of the upper surface are differently coupled.

The rotary support 120 is located between the movable support 80 and the magnet groove 103, the rotary support 120 is fixedly coupled to the hinge shaft 30, the movable support 80 and the magnet groove 103 It is coupled to the housing 100 in a state in which rotation is impossible.

When the attraction force (or repulsive force) generated between the inner surface of the movable support 80 and the angle adjusting magnet 70 coupled to the inner surface of the rotary support 120 is the strongest, respectively, on the inner surface of the rotary support 120 and the magnet groove 103. The magnet hinge is configured so that the repulsive force (or attractive force) generated between the combined angle adjustment magnet 70 is the strongest.

That is, when the hinge shaft rotates to the right (or left) by the magnetic force generated between the inner surface of the movable support 80 and the angle adjusting magnet 70 coupled to the inner surface of the rotary support 120, the inner surface of the rotary support 120 and The hinge shaft rotates to the left (or right) by the magnetic force generated between the angle adjusting magnet 70 coupled to the magnet groove 103.

At this time, if the thickness of the angle adjustment magnet 70 coupled to the inner surface of the movable magnet support 80 and the rotary support 120 and the magnet groove 103 is the same, the hinge shaft 30 is an angle adjustment magnet coupled to three places Forces are balanced by the attractive force and repulsive force generated between the 70 to maintain the hinge axis 30 is stopped at an arbitrary angle, the hinge shaft 30 with an external force greater than the strength of the magnetic force When rotated, the hinge shaft 30 stops rotating.

(Amless) In the magnetic hinge applied to the door closer or glass hinge, the thickness of the angle adjusting magnet 70 is coupled to the inner surface of the movable support 80 and the inner surface of the rotary support 120, the thickness of the magnet groove 103 It is configured to be thicker than the thickness of the angle adjusting magnet 70 is coupled to.

(Amples) Door closers or glass hinges should be kept closed at all times as the wind is blowing, and the doors should be automatically closed regardless of the wind strength.

Therefore, the rotational force generated between the inner surface of the rotation support 120 and the angle adjusting magnet 70 coupled to the magnet groove 103 acts as a counter force to overcome the strength of the wind, the inner surface of the movable support 80 and the rotation support ( 120) The door opened by the difference between the thickness of the angle adjustment magnet 70 coupled to the inner surface and the thickness of the angle adjustment magnet 70 coupled to the magnet groove 103 is always closed or opened automatically while maintaining a constant speed. do.

Next, with reference to the accompanying drawings, the speed adjusting magnet 71 which can adjust the speed in the (armless) door closer or the glass hinge just before the door is closed is as follows.

2A and 2B, the speed control magnet 71 is a ring magnet cut at an angle of about 30 °, and a pair of speed control magnet grooves 107 and the speed control magnet support formed in the housing 100 ( The magnetic force is coupled to the pair of speed adjusting magnet grooves 131 formed at 130, respectively.

At this time, the speed control magnet grooves 107 formed in the housing 100 and the speed adjustment magnet grooves 131 formed in the speed control magnet grooves 131 formed in the speed control magnet support 130, respectively, have the same magnetic poles facing each other. Are arranged.

2A is a state in which the door is generally open without repulsive force, and FIG. 2B is a state in which the door is closed with strong repulsive force.

In the case of the (armless) door closer which opens and closes the door in one direction, as shown in FIG. 2B, when the repulsive force is the strongest, the door is set to open at about 5 °, and the speed at which the open door closes at 20 ° decreases and at 5 °. The moment it slows down and closes, it acts to speed up again.

In addition, in the case of the glass hinge for opening and closing the door in both directions, the closing speed of the open door is reduced from 15 degrees, so that the speed becomes the slowest at the moment of closing.

On the other hand, the angle adjustment magnet 70 and the speed adjustment magnet 71 can be changed in design to a more diverse structure, of course.

Next, the operation of the present invention made as described above will be described with reference to the accompanying drawings.

First, when the magnetic hinge according to the first embodiment of the present invention shown in Figures 3 to 4 is applied to the hinge, the fixed coupling portion 10 is fixed to the door frame and the rotary coupling portion 20 is fixed to the door A pair of angle adjustment magnets 70 are coupled to a pair of magnet supports 50 by magnetic force, and two or more magnet hinges may be installed depending on the weight of the door, and a pair of angle adjustments are generally made. When the attraction force between the magnets 70 is the strongest is installed so that the door is closed.

At this time, when the ring-shaped angle adjustment magnet 70 is divided into four, the door can be opened up to 180 ° and the door is 90 ° or less due to manpower and repulsion generated between the pair of angle adjustment magnets 70. When opened, the door is automatically closed, and when the door is opened more than 90 °, the door is automatically opened to 180 ° to maintain the open state.

In addition, when the ring-shaped angle adjustment magnet 70 is divided into two, the door can be opened up to 180 °, and the door opened by manpower and repulsive force generated between the pair of angle adjustment magnets 70 is automatically closed. do.

In addition, when the ring-shaped angle adjustment magnet 70 is divided into six equal parts, the door can be opened up to 120 °, and the door is opened to 60 ° or less due to the attraction and repulsion generated between the pair of angle adjustment magnets 70. It closes automatically, and when the door is opened more than 60 °, it automatically opens to 120 ° to keep it open.

On the other hand, when the force generated between the pair of angle-adjusting magnets 70 is the strongest when the door is set to the open state at approximately 5 °, the door is always kept open at 5 ° like a cubicle hinge, ventilation It is free and easy to use.

When the magnetic hinge according to the second embodiment of the present invention shown in Figures 5 to 6 to 7 is applied to the hinge having a large diameter of the knuckle, the door is heavy or installed in a windy fixed coupling portion 10 is fixed to the door frame and the rotary coupling portion 20 is fixed to the door.

The speed adjusting screw 40 coupled to the hinge shaft 30 in the form of a screw maintains the state coupled with the moving support 80 by the magnetic force of the angle adjusting magnet 70 coupled to the inner surface of the moving support 80. .

The speed adjusting screw 40 can be adjusted by applying an external pressure to the rotating hole 42 through the speed adjusting hole 15 with a general driver tool, and the moving support 80 according to the operation of the speed adjusting screw 40 is It moves up and down along the guide groove 14 formed in the fixing knuckle (11).

By adjusting the speed adjusting screw 40, the moving support 80 is moved up and down while the distance between the rotating magnet groove 22 and the moving support 80 is adjusted to be generated between the pair of angle adjusting magnets 70. The strength of the magnetic force can be adjusted.

That is, when the distance between the pair of angle adjustment magnets 70 coupled to the inner side of the rotating magnet groove 22 and the movable support 80 is close, the magnetic force becomes stronger and the magnetic force becomes weaker when the distance is farther away.

Therefore, by adjusting the speed adjusting screw 40, the opening and closing speed of the door can be adjusted accordingly.

When the ring-shaped angle adjusting magnet 70 coupled to the inner side of the rotating magnet groove 22 and the moving support 80 is divided into four portions, the door can be opened up to 180 ° and between the pair of angle adjusting magnets 70. When the door is opened below 90 ° by the manpower and repulsive force generated from the door, the door is automatically closed when opened above 90 °.

In addition, when the ring-shaped angle adjustment magnet 70 coupled to the inner side of the rotating magnet groove 22 and the moving support 80 is divided into two, the door can be opened up to 180 ° and the open door is a pair of angles. It is automatically closed by the attraction force and repulsive force generated between the adjustment magnet (70).

Meanwhile, the hinge having a large diameter of the knuckle has two or three magnet hinges installed in one door because the hinge is installed in a heavy or windy place.

When two magnetic hinges (upper magnet hinge, lower magnet hinge) are installed in one door, the arrangement of the angle adjusting magnets 70 coupled to the upper magnet hinge and the lower magnet hinge are opposite to each other to close the door. Both the rotational force and the rotational force that opens the door will act.

These two turning forces serve to automatically close the door at a constant speed while preventing it from being closed or opened by the wind.

The thickness of the pair of angle adjustment magnets 70 coupled to the upper magnet hinge is configured to be thicker than the thickness of the pair of angle adjustment magnets 70 coupled to the lower magnet hinge, and the thickness difference of the two pairs of angle adjustment magnets The open door is then automatically closed or fully open.

At this time, the opening and closing speed of the door is determined by the difference in the thickness of the two pairs of angle adjustment magnets 70, the larger the difference in thickness is faster the opening and closing speed, the smaller the difference in thickness is slow opening and closing speed.

When three magnet hinges (upper magnet hinge, center magnet hinge, lower magnet hinge) are installed in one door, the three pairs of angle adjusting magnets 70 coupled to the upper magnet hinge, the central magnet hinge and the lower magnet hinge The thickness is all the same, the arrangement of the angle adjustment magnets 70 of the upper magnet hinge and the lower magnet hinge is the same, and the arrangement of the angle adjustment magnets 70 of the central magnet hinge is installed to be reversed.

The repulsive force (or attractive force) is generated most strongly in the central magnet hinge when the attractive force (or repulsive force) generated by the upper magnet hinge and the lower magnetic hinge is the strongest.

That is, since the strength of the magnetic force generated in the lower magnet hinge and the central magnet hinge is equal to each other and act in the opposite direction, the balance of the force is made, the rotation is not made to the external force (wind strength) that does not exceed the strength of the magnetic force.

However, the opening and closing speed of the door is determined by the strength of the magnetic force generated in the upper magnet hinge, it is possible to adjust the opening and closing speed of the door accordingly by adjusting the speed adjusting screw 40 of the upper magnet hinge.

When the magnetic hinge according to the third embodiment of the present invention illustrated in FIGS. 8 to 9 to 10 is applied to an armless door closer installed outside the front door or a buried armless door closer installed inside the front door The hinge is installed at the upper side of the door, the housing 100 is fixed to the door through a plurality of fixing holes 201 formed on the upper surface of the cover 200, and the hinge shaft penetrates the housing 100 ( 30) The hinge shaft 30 is fixed to the door frame through the connecting portion 33 at the top.

The specific installation method is generally omitted because it follows the installation method.

The speed adjusting screw 40 coupled to the upper portion of the housing 100 in the form of a screw maintains the state coupled with the moving support 80 by the magnetic force of the angle adjusting magnet 70 coupled to the inner surface of the moving support 80. Done.

Operation of the speed adjusting screw 40 is made by applying an external pressure with a driver tool to the rotating hole 42 through the speed adjusting hole 101 formed on one side of the upper part of the housing 100, and moves outside the support 80. The moving support protrusion 81 formed on the symmetry line is moved up and down along the guide groove 104 formed in the housing 100.

Therefore, by adjusting the speed adjusting screw 40, the distance between the inner surface of the movable support 80 and the angle adjusting magnet 70 coupled to the inner surface of the rotary support 120 is adjusted to adjust the strength of the magnetic force.

Therefore, by adjusting the speed adjusting screw 40 it is possible to adjust the opening and closing speed of the open door accordingly.

On the other hand, the angle adjustment magnet 70 is coupled to the inner surface of the moving support 80 and the rotary support 120 and the magnet groove 103, respectively, the ring-shaped angle adjustment magnet 70 is divided into two doors It can be opened up to 180 ° and automatically closed by the magnet's attraction and repulsive force.

In addition, when the ring-shaped angle adjustment magnet 70 is divided into four parts, the door can be opened up to 180 ° and automatically closed when the door is opened at 90 ° or less due to the attraction and repulsive force of the magnet. When opened, it automatically opens to 180 ° and stays open.

In addition, the speed at which the door opened by the speed regulating magnet 71 is closed at approximately 20 ° decreases, and the speed is increased again at the moment of closing and closing the most at about 5 °.

As shown in FIG. 11, when the magnetic hinge of the present invention is applied to a door closer connected to an arm, the magnetic hinge is fixed to the door through a plurality of screw holes 111 formed in the fixed coupling part 110, and the housing ( The hinge shaft 30 is fixed to the door frame through the connecting portion 33 of the upper end of the hinge shaft 30.

The action of the door closer connected to the arm is the same as that of the above described armless door closer and thus will be omitted.

As shown in FIG. 12, when the magnetic hinge of the present invention is applied to a glass hinge installed in a tempered glass door, the magnetic hinge is installed at a lower side (or an upper side) of a corresponding door, and the coupling formed at the coupling part 310. Tempered glass is fixedly coupled to the groove 311, and is coupled to a fixture (not shown in the drawing) provided on the bottom surface of the building via a connecting portion 33 at the bottom of the hinge shaft 30 penetrating the assembly 300. .

Since the action of the speed adjusting screw 40 in the glass hinge is the same as that of the armless door closer described above, it is omitted.

The angle adjusting magnet 70 is coupled to the inner surface of the moving support 80, the rotating support 120 and the magnet groove 103, respectively, and the door 180 ° when the ring-shaped angle adjusting magnet 70 is divided into four The door is automatically closed when the door is opened at 90 ° or less in both directions (or one direction) due to the attraction and repulsion of the magnet, and automatically opened at 180 ° when the door is opened at 90 ° or more in both directions (or one direction). Will remain open.

In addition, when the ring-shaped angle adjustment magnet 70 is divided into two, the door can be opened up to 180 ° in both directions and is automatically closed by the attraction force and repulsive force of the magnet.

On the other hand, the door opened by the speed adjusting magnet 71 serves to reduce the closing speed from approximately 15 ° in both directions so that the speed is the slowest at the moment of closing.

When the magnetic hinge according to the fourth embodiment of the present invention shown in FIG. 13 is applied to cover hinges installed on various covers (kimchi refrigerator, notebook computer, mobile phone, copy machine, fax machine, etc.), the magnetic hinge Among the portions where the end and the cover are connected, the cover (or body rear end) is embedded in the horizontal direction, and the connecting portion 33 of the hinge shaft 30 is coupled to the body rear end (or the cover).

The cover hinge size of the angle adjusting magnet 70 coupled to the inner surface of the magnet groove 103 and the rotary support 120 respectively formed on the left and right sides of the rotary support 120 so that the cover is always kept open at the open angle. Are all configured identically.

When the attractive force (or repulsive force) generated between the inner surface of the rotary support 120 and the angle adjusting magnet 70 coupled to the magnet groove 103 on the left side is the strongest, the inner surface of the rotary support 120 and the magnet groove 103 on the right side are strong. The repulsive force (or attraction) generated between the angle adjusting magnet 70 is coupled to the strongest.

That is, since the rotational force generated from the left side and the rotational force generated from the right side always have the same magnitude but the opposite direction acts on the rotational support 120, the cover is always kept in the opened state at an arbitrary angle.

At this time, it is possible to prevent the closing by the weight of the cover by adjusting the thickness of the angle adjusting magnet (70).

On the other hand, even if the modified embodiments different from the contents described in the present invention should not be understood individually from the technical spirit or prospects of the present invention, of course, it will fall within the claims attached to the present invention.

Conventional door closers or floor hinges use springs and hydraulic pressure, so that the defective rate is high in the production process, but the magnet hinge of the present invention uses permanent magnets, so the structure is simple and almost no defective products occur in the production process.

In addition, since the existing door closer or the floor hinge uses hydraulic pressure, oil leakage may always occur, but the magnetic hinge of the present invention is environmentally friendly because it does not use oil.

In addition, the magnetic hinge of the present invention is smaller than 1/3 of the size of the existing door closer, significantly smaller than the size of the existing floor hinge can greatly save resources.
