Description

Casement automatic door {AUTOMATIC DOOR}

The present invention relates to a casement automatic door, and more particularly, to a motorized casement automatic door.

In general, most of the automatic doors are configured to suspend and open and close the door to a belt that rotates in a wire or belt type caterpillar. However, such a conventional structure has pulleys installed on both sides of the belt, and one pulley is configured to connect with a reduction motor, so the structure is complicated, the number of parts is large, and it takes up a lot of volume, so that an automatic door cannot be constructed inexpensively.

In addition, such a conventional technique is not good in appearance and occupies a lot of volume. In particular, it has a separate solenoid and a clutch means of a connecting link to separate the deceleration motor and drive gear during manual operation, so the configuration is complicated and difficult to manufacture. There was a disadvantage that it was difficult to apply to the door.

As a technique for solving such a shortcoming, there is a registered patent publication No. 10-1705319 (invention name: automatic revolving door device of a doorway), but this technology is applied to a large-sized revolving door that is applied to a doorway in general. There is a problem that is difficult to apply to.

On the other hand, there is a patented patent publication No. 10-1728297 (invention name: automatic door opening and closing device) as a technology in which an automatic door opening and closing device is applied to a general casement door, but this technology has a bad aesthetic because the motor is exposed to the outside. There is a problem that the space utilization of the room is insufficient, and the guide rail is also exposed to the outside, so that it can be easily deteriorated or damaged by an external stimulus or impact.

1 is a front view of the casement automatic door according to the present invention, FIG. 2 is a perspective view of the motor according to the present invention, and FIG. 3 is a view of the casement automatic door according to the present invention as viewed from the side.

1 to 3, the casement automatic door according to the present invention is a door body 100; Located on the top of the door body 100, the hollow portion is formed inside the ramma portion 200; It may be configured to include a motor 300 installed inside the ramma 200. For reference, the casement automatic door according to the present invention is preferably configured to include a sensing unit (not shown) to automatically open and close the door body 100. That is, in the case of the automatic door opening according to the present invention, the door body 100 is automatically opened when the sensing unit detects a person, and the door body 100 is automatically closed when a person passes or no longer detects a person.

The casement automatic door according to the present invention is preferably formed at a height such that the height of the main body door 100 does not reach the ceiling, but rather a certain margin from the ceiling. As described above, a clearance gap is formed between the main body door 100 and the ceiling, and a ramma 200 may be formed at the clearance gap. For reference, the clearance between the ceiling and the door is also called the Ramma structure.

The ramma part 200 according to the present invention is preferably formed with a hollow inside, unlike a general ramma structure. In this way, by forming a hollow inside the ramma 200, a space in which the motor 300 can be installed may be secured.

In addition, the casement automatic door according to the present invention includes a motor shaft 310 connected to the motor 300; A rotating bar 320 connected to the lower end of the motor shaft 310; A roller 330 formed at one end of the rotating bar 320; And a guide rail 110 formed on the door body 100 and formed to slide the roller 330.

By such a configuration, the automatic door opening according to the present invention does not expose the motor 300 and the guide rail 110 to the outside, whereby the motor 300 and the guide rail 110 are easily deteriorated by external stimulation or impact. It can be prevented from being damaged.

Various types of motors may be used as the motor 300 according to the present invention, and a motor operated by DC power may be used, and an encoder may be installed inside to detect the number of revolutions of the motor. When an encoder is installed inside to detect the number of revolutions, more accurate motor operation can be realized.

The encoder can be used as a detector for accurately checking the rotational speed and rotational angle, including the rotational direction of the servomotor, and an optical encoder, a magnetic encoder, or the like can be used as such an encoder. The optical encoder is characterized by a simple processing circuit, a large noise margin using a digital signal, and high resolution. In addition, the magnetic encoder is characterized by a simple processing circuit, a large noise margin using a digital signal, and is relatively resistant to vibration and shock, and consumes less power than an optical encoder. In the present invention, an appropriate encoder may be selected according to the situation among the optical encoder and the magnetic encoder, and configured to be included in the motor 300.

In addition, there are two types of encoder detection methods: absolute and incremental. First, the absolute method has a characteristic that can always maintain an absolute position value regardless of the power state, which is possible by scanning an optically binary coded position code on the rotating disc, so that the position movement can be performed without power being supplied. Even if it occurs, the current location information can be checked immediately after the power is turned on.

In addition, the incremental method is a method of optically counting the number of slots arranged at regular intervals on the circumference of the rotating disk to calculate the rotation angle. The absolute position cannot be measured and only the relative position from the starting point can be measured. There is a disadvantage that the initial position must be detected again after a power interruption and recovery. However, it has the advantage of being able to construct an incremental encoder at a low cost due to its relatively simple structure.

In addition, the motor 300 according to the present invention may further include a helical reducer, and noise generation may be minimized by the helical reducer.

The casement automatic door according to the present invention is preferably provided with a control unit 340 for controlling the operation of the motor 300. Although FIG. 2 shows that the control unit 340 is installed next to the motor 300, this is only one example, and it is only necessary to control the operation of the motor 300 by sending an electric signal to the motor 300. It is not limited to the installation position of the control unit 340.

As such, the control unit 340 may control the operation of the motor 300, in particular, the degree to which the motor shaft 310 directly connected to the motor 300 rotates, that is, the rotation angle of the motor shaft 310. . In this way, the control unit 340 may control the degree of opening of the door body 100 by controlling the rotation angle of the motor shaft 310.

And the control unit 340 to control the rotation angle of the motor shaft 310 may be implemented by using an installed encoder inside the motor 300. For example, when the degree of opening of the door body 100 is determined, the rotation angle of the motor shaft 310 may be determined to correspond to this, and accordingly, the rotational speed of the motor 300 may be determined. As a result, the degree to which the door body 100 is opened is determined according to the number of revolutions of the motor 300. As such information is previously stored in the control unit 340, the degree to which the door body 100 is opened at the number of revolutions of the motor 300 Can be adjusted.

For example, when the degree to which the door body 100 is opened is pre-stored at 90 degrees, and if the corresponding number of revolutions is 1,000, the motor 300 starts to rotate and then the installed number of 1,000 is detected by the encoder installed inside the motor 300 When the motor 300 is stopped, the control unit 340 may operate. In this way, the door body 100 can be opened by 90 degrees. This method is only one example to help understand the automatic door opening according to the present invention, and the motor body 300 may be controlled in various ways to open or close the door body 100.

4 and 5 is an operation state diagram of the casement automatic door according to an embodiment of the present invention. With reference to Figures 4 and 5 through the various embodiments of the present invention, the present invention will be described in more detail.

4 shows that the door body 100 is coupled with a hinge structure. The indoor doors in the building are often combined with a hinge structure. As shown in FIG. 4, even if the door body 100 is coupled with a hinge structure, the configuration of the automatic door opening and closing according to the present invention is applied to operate.

5 shows a state in which the door body 100 is not a hinge structure. At this time, the casement automatic door according to the present invention may be configured to further include a door shaft 140 that is formed on one side inside the door body 100 and serves as a central axis of rotation of the door body 100. That is, the door body 100 is not coupled with the hinge structure, but may be configured to rotate the door body 100 with the door shaft 140 as a central axis.

At this time, the door shaft 140 is preferably disposed on the same line as the motor shaft 310 connected to the lower end of the motor 300. Even if the door shaft 140 and the rotating shaft 310 are not disposed on the same line, the casement automatic door according to the present invention is not operated, but if the door shaft 140 and the rotating shaft 310 are on the same line If it is not disposed in, the weight (force) applied when the door body 100 is rotated to be opened and the door body 100 is rotated to be closed is different, so durability may be deteriorated in the long term. However, the casement automatic door door shaft 140 and the rotating shaft 310 according to the present invention can be prevented from being deteriorated in durability as described above by being disposed on the same line.

In addition, the casement automatic door according to the present invention is provided with a plurality of rotating bars 320 so that the angle at which the door body 100 is opened is 90 degrees or more (when viewed from above as in FIGS. 4 and 5), and a plurality of rotations Bar 320 may be configured to have a link structure. Such a link structure may be more useful when the door body 100 is coupled with a hinge structure.

And although not shown in the drawing, if the rotary bar 320 is formed in a telescopic structure, the casement automatic door according to the present invention may have an angle at which the door body 100 is opened at 90 degrees or more. The telescopic structure is a structure that can be extended or reduced by overlapping a part, and a detailed description thereof will be omitted because it is a well-known technology that is widely used.

In addition, the casement automatic door according to the present invention may be configured to include at least one electromagnet. 1 shows that the electromagnets 120 and 130 are installed at both ends of the guide rail 110. At this time, the roller 330 is preferably configured to include metal so that it can operate in response to the electromagnets 120 and 130 installed at both ends of the guide rail 110. The entire roller 330 may be formed of metal, or only a portion of the roller 330 may be formed to include metal. In this case, the electromagnets 120 and 130 may be implemented to be turned on/off by the control unit 340.

The operation of the casement automatic door according to the present invention having such a configuration will be described. First, when the door body 100 is closed, the roller 330 is positioned close to the electromagnet 120 on the left side of the door body 100 in FIG. 4, and the electromagnet 120 on the left side is on. ), the door body 100 can be fixed more strongly. For reference, the casement automatic door according to the present invention may further include a separate locking structure.

When the detection unit detects a person in the state where the door body 100 is closed, the control unit 340 releases the electromagnet 120 on the left side to release the fixing of the door body 100, and the motor 300 By rotating the door body 100 may be opened.

When the opening of the door body 100 is completed, the roller 330 is placed close to the electromagnet 130 on the right side of the door body 100 in FIG. 4. At this time, the control unit 340 may be strongly fixed in the open state of the door body 100 by turning on (on) the electromagnet 130 on the right.

Such a configuration may be useful to a user, for example, a button that a user may press or touch may be formed on a casement automatic door according to the present invention. ), the electromagnet 130 on the right in FIG. 4 can be turned on so that the open state is maintained. For example, when a user needs to move a plurality of objects repeatedly while moving back and forth through the door body 100, the user can press the button to keep the door body 100 open and utilize it.

In addition, the casement automatic door according to the present invention may be further provided with a lubricant supply portion on one or both ends of the guide rail (110). 6 is a state in which the lubricant supply units 150 and 160 are installed at both ends of the guide rail 110. At this time, it is preferable that the guide rail 110 is further formed with a lubricant supply port (not shown) for supplying the lubricant from the lubricant supply units 150 and 160.

For example, the lubricating oil supply parts 150 and 160 are installed at both ends of the guide rail 110 and are configured to include a pressing part pressed by the roller 330 and a lubricating oil storage part connected to the pressing part to store lubricant therein. In this case, when the motor 300 starts to rotate and the roller 330 presses the pressing portion, the lubricant stored in the lubricant storage unit may flow into the guide rail 110 through the lubricant supply port.

More specifically, the pressing portion may be composed of an elastic material such as a spring, and the lubricant storage portion may be composed of a material such as a sponge, and at this time, the lubricant may be stored in the sponge. In this state, the spring is pressed by the roller 330, and the spring presses the sponge so that the lubricant inside the sponge can flow into the guide rail 110 through the lubricant supply port.

In addition to this type, a configuration of a pump using a pressure difference is applied, and the lubricant supply units 150 and 160 may supply lubricant to the guide rail 110.

Referring to FIG. 6, when the door body 100 is opened, the lubricant supply unit 150 installed on the left side of the guide rail 110 is pressurized by a roller 330 to supply lubricant, and the door body 100 is closed When possible, the lubricant supply unit 160 installed on the right side of the guide rail 110 may be pressurized by the roller 330 to supply lubricant.
