Figure 2 is an enlarged view of a swing door including the swing control device of the present invention according to one embodiment.

A swing door including a swing control device according to an embodiment may include a first frame 10, a second frame 20, and a swing control device 100. The first frame 10 is a frame that serves as a reference frame for a swing door including a swing control device and may be formed in a shape (for example, a square). Therefore, an empty space may be formed inside the first frame 10, and the second frame 20 may be located inside the first frame 10.

The second frame 20 may be disposed on the inner side of the first frame 10 and connected to the first frame 10 to be rotatable about one axis. For example, with reference to Figure 1, the right side (one side) of the first frame 10 and the right side (one side) of the second frame 20 are arranged to face each other, and the second frame 20 has the upper and lower sides. may be rotatably connected to the upper and lower surfaces of the first frame 10, respectively, about an axis. Therefore, the second frame 20 can be rotated based on the first frame 10. Meanwhile, a panel may be placed inside the second frame 20, and a handle may also be connected to the second frame 20.

The swing control device 100 may be disposed in the second frame 20. The swing control device 100 may be disposed on the lower right side of the second frame 20. The swing control device 100 may apply resistance when the second frame 20 rotates with respect to the first frame 10. That is, the swing control device 100 rotates the second frame 20 in the front direction based on the right side with respect to FIG. 1 and then moves rearward and when the second frame 20 attempts to return to its original position, the second frame 20 ), the second frame 20 can be rotated slowly by applying a resistance force, which is a force directed in the front direction.

Additionally, the swing control device 100 can prevent the second frame 20 from rotating beyond a specific angle. Therefore, the swing control device 100 can solve the problem of damage caused by direct collision between the first frame 10 and the second frame 20.

This may be possible due to the operation and connection relationship of the damping unit 200 and the angle control frame 300 of the swing control device 100. Below, we will first look at the configuration for applying the resistance force of the swing control device 100, and then we will look at the configuration for preventing collision between the frames 10 and 20.

Additionally, the swing control device 100 according to one embodiment can provide convenience in construction, and these features will be discussed at the end.

Figure 3 is an exploded view of the damping part of a swing door including the swing control device of the present invention according to an embodiment, and Figure 4 is an operation diagram of the damping portion of the swing door including the swing control device of the present invention according to an embodiment.

Below, we will first look at the configuration for applying the resistance of the swing control device.

The damping unit 200 of a swing door including the swing control device of the present invention according to one embodiment can apply a force to resist the movement of the second frame 20 to cause the second frame 20 to move slowly. .

As can be seen from FIG. 3 , the damping unit 200 may include a case 210, a rotation axis 220, a moving body 230, and an elastic body 240.

Case 210 may be composed of a first case 211 and a second case 212.

Here, the first case 211 may include a long part so that the elastic body 240 can be disposed, and the second case 212 is in communication with the first case 211 and includes a rotation axis 220 and a moving body 230. etc. may be placed. The inside of the case 210 may be filled with fluid (not shown). The fluid located inside the case 210 may apply a resistance to the movement of the mobile body 230.

The rotation axis 220 may be placed inside the case 210. Here, the upper part of the rotation axis 220 may be closed by the case 210 (more precisely, the second case 212), but the lower part of the rotation axis 220 is disposed of the angle control frame 300 (see FIG. 6). It may be placed in a frame 310 (see FIG. 6). The rotation axis 220 may be the center of rotation of the second frame 20.

That is, the second frame 20 may be rotated clockwise or counterclockwise around the rotation axis 220.

Looking at the configuration shown in FIG. 3 and the operation of the configuration shown in FIG. 4, the rotation axis 220 may be composed of at least a portion of the flat portion 221 and the protruding portion 222. That is, the rotation shaft 220 is formed as a whole in the shape of a cylinder, but at least some areas are formed with a flat portion 221 on one side, and the other side is formed with a diameter larger than the cylindrical diameter of the rotation shaft 220. do. Therefore, the rotation axis 220 may have different radial lengths based on the center. This rotation axis 220 may be inserted into and placed in the moving body 230.

The mobile body 230 may include an arrangement unit 231. When the placement portion 231 of the moving body 230 is aligned, it may be positioned in contact with the flat portion 221. The horizontal length of the placement portion 131 may be at least longer than the horizontal length of the protrusion 222 of the rotation axis 220.

Meanwhile, since the moving body 230 is positioned in contact with the flat portion 221 of the rotation axis 220, the moving body 230 moves along the rotation axis by the rotation of the second case 212 when the second frame 20 rotates. It can be rotated relative to 220 and moved forward or backward accordingly. As shown in (b) of FIG. 4, when the second case 212 is rotated counterclockwise about the rotation axis 220, the moving object 230 is pushed by the changed radius of the rotation axis 220 and moves away from the rotation axis 220. It can be moved (advanced) toward, thereby pressurizing the elastic body 240.

Conversely, when the door is rotated as shown in (a) of FIG. 4, the moving body 230 may be pushed by the pressed elastic body 240 and move (reverse) in the direction of the rotation axis 220. Here, the fluid may be located between at least the moving body 230 and the case 210. Therefore, the speed of movement of the moving object 230 can be controlled.

That is, the other side of the second frame 20 (see FIG. 1, not shown in FIGS. 4(a) and (b)) is on the first frame 10 (see FIG. 1, not shown in FIGS. 4(a) and (b)). When moved to face the other side of the second case 212 (not shown), the second case 212 may be rotated counterclockwise about the rotation axis 220 (see (a) of FIG. 4), and in this case, the moving body 230 ) can be moved to the right based on (a) of Figure 4.

At this time, at least fluid may be located between the moving body 230 and the case 210. The fluid may be located in a sealed space between the moving body 230 and the case 210. Therefore, when the moving object 230 is to be moved to the right, a resistance force can be applied to the movement of the moving object 230. Resistance applied to the mobile body 230 can control the movement of the mobile body 230.

The elastic body 240 may be connected to one surface of the moving body 230. Here, the elastic body 240 is formed to be long, so that one side can be connected to the first case 211 and the other side can be connected to the moving body 230. Therefore, when the rotation axis 220 is rotated, the elastic body 240 is pressed by the moving body 230, and when the force rotating the rotation axis 220 disappears, the elastic body 240 pushes the moving body 230 by elastic force and the moving body 230 ) can be moved to its original location.

In this way, in the present invention, when the second frame 20 rotates, the moving body 230 moves forward and backward due to the size of the radius of the rotation axis 220, and the elastic body 240 exerts a force opposing the movement of the moving body 230. In addition, since the fluid disposed in the case 210 is located between the elastic body 240 and the moving body 230 and interferes with the movement of the moving body 230, the moving speed of the second frame 20 can be slowed. Therefore, the swing door including the swing control device of the present invention can prevent hands from being caught.

Meanwhile, the damping unit 200 of the present invention may further include a flow path control pin 250. The flow path control pin 250 can further widen or narrow the path of the flow path located inside the case 210. Therefore, the force that resists the movement of the second frame (20 - see FIG. 1) can be controlled due to the operation of the flow control pin 250.

Figure 5 shows the problem of collision between frames of a conventional swing door, and Figure 6 shows a placement frame and a rotation frame, which are angle control frames of a swing door including the swing control device of the present invention according to an embodiment. , Figure 7 is an operation diagram of the arrangement frame and rotation frame of the swing door including the swing control device of the present invention according to one embodiment.

Hereinafter, we will look at the configuration of the swing control device 100 to prevent collision between the frames 10 and 20.

As can be seen in Figure 5, the conventional swing door has a problem of being damaged due to collision between frames and panels or between frames due to rotation.

In order to solve this problem, the present invention uses the arrangement frame 310 and the rotation frame 3500 of the angle control frame 300 to control the rotation angle of the second frame (20 - see Figure 1) due to collision between the components. , each component can be prevented from colliding.

According to one embodiment of the present invention, the swing control device 100 includes an angle control frame 300 on the lower side. The angle control frame 300 may include a placement frame 310 and a rotation frame 350.

As can be seen with reference to FIG. 6 , the arrangement frame 310 may include a length portion 311 and a seating portion 312.

The placement frame 310 may be placed in the first frame 10. Here, the arrangement frame 310 may be arranged so that it does not rotate together with the second frame 20.

The length portion 3111 of the arrangement frame 310 is formed to be long in the vertical direction and may be placed in a cutout portion (no reference number) of the first frame 10. And the seating portion 312 may be formed to extend in one direction from the end of the length portion 311 of the arrangement frame 310. Here, the length portion 311 is formed to have a vertical length, the lower end is formed to protrude along the horizontal direction, and the seating portion 312 is a groove to accommodate the portion protruding along the horizontal direction of the length portion 311. This can be formed. Therefore, the length portion 311 and the seating portion 312 can be fixed in a manner in which a portion of the length portion 311 is inserted into the seating portion 312.

Stop protrusions 313 may be disposed along both sides of the seating portion 312 of the arrangement frame 310. The stop protrusions 313 are formed to protrude on both sides as shown in FIG. 6 and can be arranged so as not to interfere with the position of the adjustment pin 330 (see FIG. 9), which will be described later. The stop protrusion 313 is formed on the seating portion 312 in a direction close to the length portion 311. Therefore, the stop protrusion 313 can form a space where the rotation frame 350, which will be described later, can be rotated at a set angle, and can prevent further rotation if it is rotated beyond the set angle.

A rotating frame 350 may be disposed on the seating portion 312 of the placement frame 310. The rotating frame 350 may be spaced apart from the seating portion 312 and connected through the aforementioned rotating shaft 220, and may be connected to the lower side of the second case 212. Therefore, the rotation frame 350 can be rotated accordingly when the second case 212 is rotated. (Meanwhile, the rotating frame 310 is also connected to the adjustment plate 400, which will be described later) A limiting protrusion 351 protruding downward and in the horizontal direction may be disposed on one side of the rotating frame 350. Therefore, looking at the present invention with reference to FIG. 7, the present invention is that when the second frame 20 is rotated based on the rotation axis 220, the second case 212 is rotated accordingly, and therefore, the frame connected to the second case 212 The rotation frame 350 is also rotated together.

Here, when the rotation frame 350 is arranged to overlap the arrangement frame 310, the limiting protrusion 351 is formed on the rotation frame 350 at a distant position away from the stop protrusion 313 formed on the arrangement frame 310. . Additionally, the limiting protrusion 351 extends to both sides and extends downward. Therefore, the shape of the rotating frame 350 may be formed in the shape of a 'T' where the horizontal length of one side is longer than the horizontal length of the other side. Here, the limiting protrusion 351 extends to both sides and downward when the rotation frame 350 is arranged side by side with the arrangement frame 310, and may be formed so that the formed limiting protrusion 351 does not contact the arrangement frame 310. .

However, when the second case 212 is rotated more than the set angle, the rotation frame 350 is rotated, and as a result, the limiting protrusion 351 comes into contact with the stop protrusion 313 of the arrangement frame 310, preventing further rotation. This may become impossible.

Therefore, only the rotation frame 350 and the arrangement frame 310, which are not visible, may be in contact with each other, and the remaining components may not be in contact with each other. Therefore, in the present invention, damage due to collision between frames may not occur.

Figure 8 shows an arrangement frame and an adjustment plate of a swing door including the swing control device of the present invention according to an embodiment, and Figure 9 shows an arrangement frame of a swing door including the swing control device of the present invention according to an embodiment. and an exploded view of the control plate, and Figure 10 is an operation diagram of the control plate of a swing door including the swing control device of the present invention according to one embodiment.

Below, we will describe a configuration that enables convenience of construction, which is an additional feature of the swing control device of the present invention.

The present invention according to one embodiment may further include an adjustment plate 400. The above-described second case 212 is connected together with the rotation frame 350, and the rotation frame 350 can be rotatably disposed on the arrangement frame 310. And the rotation axis 220 can be arranged to be fixed to the control plate 400 as an axis. Therefore, the position of the damping unit 200 may change depending on how the rotation axis 220 is connected to the arrangement frame 310. In other words, as it becomes easier to change the position of the damping unit 200, construction can also become easier for workers.

In the present invention, the position of the damping part (200 - see FIG. 3) and, further, the position of the second frame (20 - see FIG. 1) can be easily changed through the arrangement frame 310 and the adjustment plate 400.

A placement hole 314 may be formed in the seating portion 312 of the placement frame 310. The control plate 400 includes a fixing hole 430 and may be located in the placement hole 314.

The placement hole 314 of the placement frame 310 may include a first placement hole 314a and a second placement hole 314b. The first arrangement hole 314a may refer to a part having a first horizontal length l1, and the second arrangement hole 314b may refer to a part having a second horizontal length l2. Here, the first horizontal length (l1) may be longer than the second horizontal length (l2). The arrangement frame 310 may further include an inclined portion 315. The inclined portion 315 may be formed to narrow the first horizontal length of the first arrangement hole 314a. Therefore, when the control plate 400 is disposed, the reference position can be set due to the inclined portion 315.

The control plate 400 may include a first control plate 410 and a second control plate 420.

The first control plate 410 is a portion having a first horizontal length l1 corresponding to the first arrangement hole 314a, and a fixing hole 430 may be formed in the center portion. The second control plate 420 extends from the first control plate 410 and may have a length corresponding to the second horizontal length l2 of the second arrangement hole 314b.

Here, the horizontal length of the first control plate 410 and the second control plate 420 is the first horizontal length (l1) of the first arrangement hole (314a) and the second horizontal length (l2) of the second arrangement hole (314b). ) is formed no longer than that. Therefore, when the first control plate 410 and the second control plate 420 are placed in the arrangement hole 314, a space can be formed.

Here, when the adjustment plate 400 is located in the placement hole 314, both sides of the adjustment plate 400 may be pressed due to the inclined portion 315 of the placement frame 310.

And an adjustment pin 330 may be disposed on the arrangement frame 310. The control pin 330 may be located on both sides of the inclined portion 315. That is, the control pin 330 may be placed in a position symmetrical with respect to the arrangement hole 314 of the arrangement frame 310. Therefore, the control pin 330 may include a first control pin 331, a second control pin 332, a third control pin 333, and a fourth control pin 334. Each control pin 330 may pass through the placement hole 314 and press the control plate 400 located in the placement hole 314. Therefore, the position of the control plate 400 can be changed depending on the depth at which each control pin 330 is inserted into the arrangement frame 310.

For example, when the first control pin 331 is deeply inserted and the second control pin 332 is shallowly inserted, the control plate 400 has a shape inclined in the direction of the first control pin 331, and the third control pin 331 is inserted shallowly. When the control pin 333 is deeply inserted, the control plate 400 moves again in the direction of the second control pin 332, and when the fourth control pin 334 is deeply inserted again, it moves in the direction of the third control pin 333. It will be. In this way, the present invention can change the position of the control plate 400 by adjusting the insertion depth of each control pin 330.

Therefore, the position of the rotating shaft 220 entering the fixing hole 430 of the control plate 400 is also changed, and as a result, the position of the damping unit 200 can be changed. In this way, the present invention can change the position of the damping part 200 in a simple way during construction, so design errors, etc. can be easily overcome at the construction site.

Meanwhile, the control plate 500 may be placed in the arrangement hole 314 of the arrangement frame 310 before the adjustment plate 400 is placed. The control plate 600 is formed in a shape corresponding to the control plate 400. The control plate 500 may be located in the placement hole 314 of the placement frame 310 when it is necessary to adjust the height of the adjustment plate 400.

Above, an embodiment of the present invention has been described, but those skilled in the art can add, change, delete or add components without departing from the spirit of the present invention as set forth in the patent claims. The present invention may be modified and changed in various ways, and this will also be included within the scope of rights of the present invention.
