The support bracket 110 is made of a solid material including steel and is provided in a plate shape, and is a support body having a fixing means coupling hole 117 through which bolts can pass through to be fixed to a support body such as a door frame with bolts. 111, a support through-hole 113 to which the rotary shaft 150 can be coupled to one side, preferably an end of the support body 111, and a pressing portion 175 in the support through-hole 113 using a screw, etc. It is preferable to have a press coupling member 115 that can be coupled in a variety of ways including.

Although the support bracket 110 is shown as having a pair of support through-holes 113 provided above and below the support body 111, the position or number of the support through-holes 113 may be selected from known ones.

The engaging portion 171 and the engagement portion 173 of the friction portion 170 are coupled to or accommodated in the support through hole 113 of the support bracket 110 .

The rotating bracket 130 is made of a solid material including iron and is provided in a plate shape, and has a rotating body having a coupling means coupling hole 117 through which bolts can pass through to be fixed to a support body such as a door frame with bolts. 131 and, preferably, one side of the rotation body 131, preferably provided with a rotation through-hole 133 that can be coupled to the rotation shaft 150 at the end.

Although the rotation bracket 130 is illustrated as having one rotation through hole 133 in the rotation body 131, the position or number of rotation through holes 133 may be selected from known ones.

The shaft body 151 of the rotation shaft 150 is integrally and rotatably coupled with the rotation bracket 130 to the rotation through hole 133 of the rotation bracket 130 . The combination of the rotational through-hole 133 and the rotational shaft 150 is performed by pressing the rotational through-hole 133 with a press or the like after the rotational shaft 150 is inserted into the rotational through-hole 133. And the rotating shaft 150 may be coupled to each other to rotate integrally.

In another embodiment, as shown in FIG. 2, the rotary shaft 150 is provided with a shaft step 153 having a polygonal cross section including a hexagonal shape, and a shaft step coupling groove (not shown) corresponding to the rotation through hole 133 Is provided so that the rotation shaft 150 and the rotation bracket 130 are integrally rotated by interlocking with each other.

The rotating shaft 150 has a shaft body 151 provided in a rod shape, and a hooking portion 171 provided in a conical protruding sharp protruding shape or a funnel shape is formed at a portion extending downward from the shaft body 151 has been

The rotating shaft 150 may be integrally formed, but as shown in FIG. 2B, it is divided up and down into three (see 151-1, 153-1, and 171-1), and the three are combined up and down, respectively, to form a single rod. may be provided.

In addition, as described above, it is also preferable that a shaft step 153 having a polygonal cross section is provided in the middle of the shaft body 151 of the rotation shaft 150 so as to engage with the rotation through hole 133.

The friction part 170 is a key part of the present invention, and is preferably provided as the engaging part 171 and the engagement part 173.

The hooking portion 171 is formed pointedly downward (refer to the central axis (O) and inclined angle 'A1' in FIG. Surface contact may be made with the engaging portion 173 having an angle 'A2').

Here, it is preferable that the angle 'A1' of the hooking part 171 is equal to or slightly smaller than the angle 'A2' of the engaging part 173.

In addition, the engagement portion 173 coupled to the support through-hole 113 on the lower side may be coupled to the support through-hole 113 by an interference fit or a stop pin (not shown). The engaging portion 173 has a structure that does not rotate in order to generate frictional force with the engaging portion 171 that rotates.

In addition, as the angle 'A1' decreases, the surface contact area between the engaging portion 171 and the engaging portion 171 gradually increases, so the frictional force between the engaging portion 171 and the engaging portion 173 gradually increases and the rotational axis ( 150) becomes large. Accordingly, while the rotation bracket 130 rotates with respect to the support bracket 110, the rotation shaft 150 is moved by the frictional force generated between the friction parts 170 at an arbitrary angle between the maximum open position and the closed position. It can be stopped more easily, and the rotating bracket 130 can be rotated when the user applies a force that overcomes this frictional force to the rotating body.

The friction part 170 is known to include a screw in the press-coupled member 115 of the support bracket 110 to press the engaging part 171 of the rotation shaft 150 toward the engagement part 173 with respect to the support bracket 110. It is preferable to include a pressing portion 175 coupled in a variety of ways. There is a '+' or '-' shaped recessed groove at the top of the pressing part 175, so that the pressing part 175 can be effectively detached from the pressing coupling member 115 using a tool such as a screwdriver. In the state in which the pressing part 175 is coupled, the frictional force of the friction part 170 can be easily adjusted to strong or weak.

Here, the pressing part 175 may also function to prevent the engaging part 173 from rotating while being combined with the engaging part 173, and a structure in which the engaging part 173 does not rotate even if it moves up and down is preferable.

The frictional force generated between the engagement portion 173 of the friction portion 170 and the engaging portion 171 is schematically illustrated in FIG. 3 .

As shown in FIG. 3 , frictional force is generated along the contact surface while the hooking part 171 and the engaging part 173 are in surface contact due to the vertical force (see Fvertical' in FIG. 3 ) acting on the rotating shaft 150 .

As described above, the vertical force is the sum of the weight of the rotating body, for example, the door itself, and the force pressed by the pressing unit 175.

Corresponding to the size of this vertical force (Fvertical), the frictional force (refer to 'Ffiction' in Fig. 3) of FIG. 3 is issued to resist, suppress, or hinder the rotation of the rotating shaft 150, thereby generating a force greater than this resistive force, etc. The rotating body can be rotated only when applied to, and when the force is smaller than the resistance force, the rotating body including the door can maintain a stopped state, which is a stopped state.

Unlike the case shown in FIG. 1 , the hinge device 100 according to another embodiment of the present invention includes an engaging portion 173 and a hooking portion 171 as a pair vertically.

That is, the upper friction part (170-upper), the upper engaging part (171-upper) and the upper engaging part (173-upper) are mutually engaged in the area of the upper support through hole 113, and the lower friction part (170-lower) The lower engagement portion 171-lower and the lower engagement portion 173-below are engaged with each other in the area of the support through-hole 113 at the lower side.

In addition, the pressing unit 175 may be provided as one on the upper side, but may be provided as a pair on the upper and lower sides as shown in FIG. 4 . Of course, the engaging part 173 can move up and down by the pressing of the pressing part 175 up and down inside the support through hole 113, but has a structure that does not rotate with respect to the support through hole 113 or the hanging part 171. it is desirable to have

Due to this structure, a greater frictional force of the rotating shaft 150 may be generated.

In another embodiment of the present invention, as shown in FIG. 5 , the friction part 170 is interposed between the engaging part 173 and the pressing part 175 so that the pressing part 175 is engaged. Preferably, an elastic pressing member 177 including a spring for elastically pressing the part 173 toward the hooking part 171 is further included.

Even if the frictional force between the engaging part 173 and the engaging part 171 is somewhat worn due to long-term use by the elastic pressing member 177, stable frictional force can be maintained.

And, as shown in FIG. 6, the hinge device 100 according to another embodiment of the present invention has a smooth conical shape in which the shape of the engaging portion 173 and the engaging portion 171 maintains a circular shape as described above. It is not in the shape of a funnel or a funnel, but is divided at a set angle and has an engaging step 171a and an engagement step 173a.

With this structure, the rotating body can be more effectively maintained at the angle at which the engaging step 171a and the engaging step 173a are mutually engaged, and in order to rotate the stopped rotating body, the user must use the hinge device 100 as described above You have to apply more pressure.

Here, the symbol 'O', which is not described, represents the central axis of rotation of the rotation shaft 150.

On the other hand, in the hinge device 200 according to another embodiment of the present invention, as shown in FIG. 7, for example, the support bracket 210 is coupled to a door frame (not shown), and the rotation shaft 250 is installed on the upper side. The combined rotation bracket 230 is coupled to the door (not shown) so that the rotation bracket 230 rotates together with the door.

Other configurations are the same as those described above, but the rotation shaft 250 is coupled to the rotation through hole 233 of the rotation bracket 230 by interference fit or spot welding, so that it can rotate together with the rotation bracket 230. .

According to this structure, by the weight of the door coupled to the rotation bracket 230, the locking portion 171 and the engagement portion 173 may generate frictional force while being engaged and rotated.

Due to this structure, the hinge device 200 may have a simpler structure.

Also, as shown in FIG. 8, the shape of the friction part 170 may have a conical or funnel shape, and the outer circumferential surface toward the vertex may be provided in a convex or concave curve rather than a straight line.

Therefore, according to the present invention, unlike in the prior art, it is possible to provide a hinge device capable of reducing the number of parts, having a simple structure, and holding the rotating body at an arbitrary or set angle.

In addition, it is possible to provide a hinge device capable of easily manufacturing and assembling a structure of a member providing an elastic force to keep the rotating body stopped at a set angle.

Here, although various embodiments of the present invention have been illustrated and described, those of ordinary skill in the art to which the present invention pertains can recognize that the present embodiment can be modified without departing from the spirit or principle of the present invention. will be.
