The present invention is to ensure a stable joint rotation through the ball-socket-type joint body organically combined magnetic material and non-magnetic material, while the rotation available range is greatly expandable, and by applying such a ball-socket type joint body to the lighting fixture Disclosed is a technical feature that can realize a lighting fixture with a beautiful appearance and excellent user convenience.

In the following, preferred embodiments, advantages and features of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view of a ball-socket type joint body unit according to the present invention, Figure 2 is a combined perspective view of the ball-socket type joint body unit according to the present invention, Figure 3 is a longitudinal cross-sectional view of FIG.

1 to 3, the ball-socket joint unit according to the present invention includes a rotor 10 rotating with an axis, a first magnetic body 20 providing a first magnetism, and a rotor 10. And a stator 30, which supports and provides a second magnetism, and an articulation axis 50.

The rotor 10 is formed to have at least a curved surface and is rotatably or pivotally coupled to the top of the stator 30 as a member having a space (preferably a spherical space) provided therein. In particular, the rotor 10 is prevented from being separated from the stator 30 by being constrained by the first magnetic body 20 accommodated therein by the second magnet provided by the stator 30, and the rotation or pivoting movement is prevented. It becomes possible. On the other hand, the rotor 10 of the embodiment of Figures 1 to 3 is formed in a spherical shape was configured to enable both the swing and rotation operation on the top of the stator (30).

The rotor 10 is preferably formed of a nonmagnetic material. This is due to the effect of approaching the opposite polarity of the second magnetism on the stator 30 side when rotating and rotating the rotor 10 in various directions when the rotor 10 is formed of a magnetic material (that is, repulsion) This is to prevent the occurrence). Therefore, the rotor may be formed of a nonmagnetic material, but the case of forming the rotor from magnetic materials of permanent magnets or metals is not excluded.

In addition, the rotor 10 is formed of a nonmagnetic material, but preferably formed of a resin-based material having a large coefficient of friction (for example, silicone resin). This is because when the turning and rotation of the rotor 10 is completed in the direction desired by the user, the rotor 10 no longer slips or rotates due to the high friction force between the rotor 10 and the stator 30. This is to maintain the stationary state as it is at one point.

On the other hand, the rotor 10 preferably forms a plurality of through-holes penetrating through the thickness of the magnetic attraction between the first magnetic body 20 inside the rotor 10 and the second magnetic force of the stator 30 It is good to configure so that the rotor 10 is maintained more firmly coupled to the stator 30 by this.

The joint shaft 50 is installed to protrude in a vertical direction from one point of the outer circumferential surface of the rotor 10 and corresponds to a component that pivots and rotates together with the rotor 10 when it rotates and rotates. The articulation axis 50 is connected to other instruments or devices that require joint rotation to allow the instrument to articulate.

Joint shaft 50 of the embodiment of Figure 2 is composed of a coupling cap 51 formed integrally with the rotor 10 and a rod-like member 52 coupled to the coupling cap 51 perpendicularly. The rod-shaped member 52 is configured to be inserted and coupled to the hollow of the coupling cap 51 in an interference fit manner, or is formed of a bolt having a male thread formed at one end of the rod-shaped member 52, and the coupling cap 51 has an inner circumferential surface. By forming a female thread on the rod-like member 52 may be configured to be detachable screwed to the coupling cap 51.

The first magnetic body 20 is a component that provides the first magnetism and is accommodated in the inner space of the rotor 10, and the rotor 10 is acted upon by the second magnetic force and magnetic attraction provided by the stator 30. ) Serves to restrain the stator from being separated from the stator 30.

For reference, the term "magnetic material" used in the present invention is a magnetic material within the magnetic range, all materials attached to the magnet will be referred to as a magnetic material. Therefore, the magnetic material includes all kinds of metals such as permanent magnets, copper, nickel, iron, and mixtures thereof, as well as electromagnets.

The first magnetic body 20 of the present invention was formed of a permanent magnet, and in particular, a neodymium magnet having a relatively high magnetic force was employed to ensure a stable coupling state of the rotor 10. Neodymium magnets consist of neodymium-iron-boron (Nd-Fe-B) and have the largest magnetic force among the existing permanent magnets. It is manufactured by adding trace elements such as these.

In particular, the first magnetic body 20 is stored inside the rotor 10 in a state capable of freely moving in the front and rear, left and right directions in the internal space of the rotor 10, the rotor 10 is due to this structural feature The first magnetic body 20 is characterized in that it is configured to independently rotate and rotate independently of the first magnetic body 20 in a state in which the first magnetic body 20 is bound and fixed by the second magnetic body.

In addition, as long as the first magnetic body 20 is movable in the rotor 10 and the shape in which the second magnetic properties and magnetic attraction of the stator 30 can act, the shape is not particularly limited, but preferably the rotor It is good to form in spherical shape which has an outer diameter smaller than the inner diameter of (10).

This minimizes the area where the first magnetic body 20 accommodated in the rotor 10 contacts the inner circumferential surface of the rotor, so that the first magnetic body 20 moves or rotates in conjunction with the rotation and rotation of the rotor 10. This is because it is advantageous to be able to maintain the state of being bound by the second magnetism as it is.

On the other hand, preferably, the space between the inner circumferential surface of the rotor 10 and the outer circumferential surface of the first magnetic body 20 may be configured to allow the first magnetic body 20 to flow more smoothly by interposing a plurality of ball bearings. .

The stator 30 is a component that is coupled to and supports the rotor 10 and has a coupling demand 31 for seating the rotor 10 and a second magnetic body 40 for providing a second magnetism. ) For reference, the second magnetic body 40 may be configured to provide the second magnetic property by forming the stator 30 itself as a magnetic material, or may include a separate magnetic body in the internal space of the stator 30.

1 to 3 embodiment of the stator 30 is made of a cylindrical coupling portion 31 is formed on the upper portion, the second magnetic body 40 is stored in the vertical lower portion of the coupling demand 31, the second magnetic It was configured to provide.

The second magnetic body 40 that is stored inside the stator 30 may be formed of a permanent magnet or a metal material. Of course, the neodymium magnet may be preferably formed to ensure a firm coupling state of the rotor 10. It is good to use. On the other hand, the second magnetic body 40 is not particularly limited because it may be installed and fixed inside the stator 30 through an adhesive, or may be fixed by using a variety of known coupling means such as fitting grooves or support pieces.

Coupling request 31 is formed in the form of a recess recessed inward from the top of the stator 30, the rotor 10 is disposed on the top of the stator 30 by the lower end is inserted and seated in the coupling request (31) Has a bonded state.

The groove of the coupling request 31 is not particularly limited in shape if at least the lower end of the rotor 10 can be stably received, but preferably has a hemispherical shape formed with the same curvature as the outer circumferential surface of the rotor 10. It is good to form.

This increases the frictional force by increasing the contact area between the inner circumferential surface of the coupling request 31 and the outer circumferential surface of the rotor 10 as much as possible, so that the rotor 10 articulated in the direction desired by the user does not swing at a corresponding point. It is because it is advantageous to be able to maintain a stable fixed state without.

On the other hand, the rotor (10) is inserted into only a portion (preferably less than half of the volume) in the coupling request 31 will remain in the seated state, the first magnetic body 20 accommodated inside the rotor (10) The external force generated when being pulled downward by the second magnetic body 40 is applied to the rotor 10 so that the rotor 10 can rotate and rotate without departing from the stator 30.

In particular, the coupling demand 31 of the present invention is formed such that the inner diameter of the top end thereof is smaller than the outer diameter of the rotor 10, the rotor 10 is inserted into the coupling demand 31 at less than half of the total volume of the rotor 10. Characterized in that configured to have a seated coupling structure.

As described above, the ball-socket type joint body of the present invention has a configuration of the rotor 10 in which the first magnetic body 20 is movably received therein, and the rotor 10-the stator 30. Due to the coupling structure feature of), the range of rotation can be greatly expanded while ensuring stable joint rotation of the joint body.

Hereinafter, with reference to Figure 4 will be described in detail the features and effects on the joint rotation operation of the ball-socket joint unit according to the present invention.

Figure 4 is a front view showing the rotational motion of the ball-socket joint body unit according to the present invention. As shown in FIG. 4, the ball-socket articulated unit of the present invention has only a region (i.e., a lower end) of the component (i.e., the rotor) that substantially realizes joint rotation in the stator 30. As it is configured to pivot and rotate in a coupled state, it is possible to provide a greatly expanded pivot range, unlike a conventional ball-and-socket joint or joint.

Specifically, in the conventional ball-socket type joint body, at least half the volume of the component for realizing the joint rotation is inserted and coupled to the inside of the socket to prevent its separation and to allow the pivoting and rotating operation thereof. There was a structural limitation that the angle can only be less than 90 °.

However, in the ball-socket type joint body of the present invention, a component (i.e., a first magnetic body) separate from the component (i.e., the rotor) which realizes joint rotation has the rotor 10 on the stator 30. Even if less than half the volume of the rotor 10 is coupled to the stator 30 by the holding action, the rotor 10 can be stably rotated and rotated without being separated from the stator 30. Therefore, there is an excellent effect that can implement a vertical rotation angle θ1 increased by more than 90 °.

In particular, the first magnetic body 20 accommodated inside the rotor 10 can be freely flowable so that the first magnetic body 20 is bound by the second magnetic body 40 and is rotated while maintaining a fixed state without rotation. Only the former 10 can be independently rotated and rotated. Accordingly, even when the rotor 10 is rotated downward by 90 ° or more, a repulsive action due to the opposite polarity approach between the first magnetic body 20 and the second magnetic body 40 does not occur, thereby causing the rotor 10 to rotate. At any point of rotation angle θ1 of 90 ° or more, it is possible to maintain a fixed state at the position without regression caused by the repulsive force.

That is, the ball-socket type joint body of the present invention realizes the joint rotation structure of the ball (rotor) and the socket (stator) by using magnetic force, while regression of the ball (rotor) caused by the opposite polarity of the ball and the socket. By eliminating the phenomenon, the user can rotate the rotor to a certain point and then remove the force for the rotation, and there is an excellent effect that the rotor can be settled exactly as desired at one point.

The stator 60 of another embodiment of FIG. 5 is formed in a ring-shaped annular shape, and at least one support shaft 70 is integrally formed around the annular shape.

A coupling request 61 for supporting the rotor 10 is formed at the center of the annular stator 60. The coupling request 61 is formed such that the inner diameter of the uppermost end thereof is smaller than the outer diameter of the rotor 10, so that the rotor 10 is inserted and seated in the coupling request 61 at a maximum of less than half of its total volume. Characterized in that configured to have.

On the other hand, the stator 60 of the embodiment of Figure 5 is also equipped with a second magnetic material for providing a second magnetic, as in the embodiment of Figure 2, the second magnetic material of the embodiment of Figure 5 is provided with a separate permanent magnet Unlike the embodiment 2, the stator 60 itself is formed of a magnetic material and configured to provide a second magnetic property.

Accordingly, the stator 60 of the embodiment of FIG. 5 may be formed of at least one selected from a magnetic material including permanent magnets and metals, and preferably a material having a high friction coefficient with iron (Fe) in the magnetic material (eg, silicon (Si). It is better to form a mixed material of)). This is to provide a magnetic force for constraining the first magnetic body 20, and also to provide a frictional force that allows the joint rotating rotor 10 to remain stationary without slipping at a desired position.

The mixing ratio of iron and silicon suitable for achieving the above object is preferably prepared by mixing at a weight ratio of about 50:50.

As shown in FIG. 6, the lower end of the rotor 10 is coupled to the upper portion of the annular stator 60, thereby realizing the same operation as that of the embodiment of FIG. 2, thereby extending the vertical rotational angle of 90 ° or more ( [theta] 1) and can be fixed as it is without any reaction at any rotation angle point of 90 degrees or more.

Meanwhile, the embodiment of FIG. 5 shows an annular stator 60, but has a coupling requirement of the same curvature as the outer circumferential surface of the rotor 10, and is formed of a material containing metal to provide magnetic self. Of course, the same purpose can be achieved even if it is configured as a stator.

One end of the second joint shaft 54 is configured to be connected to the stator 60 of the second joint body unit 110, and the other end of the second joint shaft 54 is configured to be connected to the light source module 80 Of course, the same purpose can be achieved.

In addition, the rotor 10b or the stator 60 of the second articulation unit 110 protrudes in a direction different from the direction in which the second articulation shaft 54 protrudes (preferably in the opposite direction) ( 90) to achieve a balance with the weight of the light source module 80 coupled to the end of the second joint shaft (54).

With the above configuration, the luminaire having the ball-socket type joint body of the present invention has an extended rotational usable range as compared with the prior art and can articulate the luminaire in almost all directions, and Each component can be used as an inspection luminaire by removing only the bar light source module 80 having a coupling structure by magnetic force, thereby providing a very excellent convenience to the user.
