Description

AUTOMATIC AND MANUAL SYSTEM LOUVER}

The present invention relates to a system louver.

Conventionally, wooden louvers are fixed louvers in which main parts of the louvers are fixed and used in buildings only for the purpose of ventilation. However, according to the needs of consumers and the changes of the times, there is a demand for a system louver that is excellent in automation, such as soundproofing, interior, airtightness, etc. as well as ventilation. In order to meet the demands of the times, the present invention has been made.

Next, the conventional system louver will be described.

First, there is a hydraulic cylinder type system louver. This hydraulic cylindrical system louver implements louver automation by installing a drive such as a piston outside the louver. However, the bulky parts, such as pistons, are used to drive the system louvers, which inevitably increases their volume. In addition, these bulky driving parts are located on the outside of the system louvers (in most cases, on the side or top). As it is installed by attaching it in the form of a box), it is not beautiful in appearance.

Second, there is a system louver of Dubron motor type. The conventional AC motor (roll screen motor) is to implement the louver automation using the L - shaped bracket. The roll screen is installed on the upper part of the system louver and installed for sunshade or the like. Therefore, since the AC roll screen motor is used, the driving device must be installed on the upper side of the louver, and the size of the driving device becomes large because the size of the AC motor itself is large. Therefore, the bulky driving device is attached to the upper part of the system louver so as to protrude in the form of a box, which is not beautiful in appearance.

Third, there is a built-in system louver. The AC motor (roll screen motor) is built into the rectangular case and mounted on top of the system louver to realize louver automation. However, as described above, since the roll screen motor is installed on the upper part of the system louver, the rectangular case in which the AC motor or the like is mounted protrudes on the upper part of the system louver. In addition, since a drive device such as an AC motor is used, the volume of the drive device itself is increased.

As described above, the conventional system louver has a large volume of the drive device, and the bulky drive device is protruded to the outside of the system louver so that it is not beautiful in appearance, and the drive device protrudes from the top or side of the system louver. As a result, maintenance and repair of the system louver is difficult. It's also automatic, so you can't open and close the louver manually. In most buildings, the system louvers are operated in a central control room, which is subject to restrictions such as ventilation and light, since the louvers cannot be opened and closed inside the louver (ie inside the building). In addition, the louver cannot be opened manually even in the event of an emergency such as a power failure or fire, which may cause damage due to suffocation.

The automatic and manual system louvers of the present invention are intended to overcome the disadvantages noted above.

First, the present invention is to provide a system louver for both automatic and manual use. In addition to operating the system louver in the central control room, in case of an emergency such as a power outage or fire, the louver wing can be opened and closed manually inside the louver, so there is no restriction on ventilation or light, and it can effectively respond to an emergency. Provides automatic and manual system louvers.

Secondly, the present invention uses a small DC motor as the driving means. Unlike the conventional system louvers, the drive means can be miniaturized because a drive device for mounting a small DC motor is used without using a cylinder or an AC motor as the drive means.

Third, the drive device of the present invention is mounted inside the system louver. Unlike a conventional system louver, the drive unit is mounted inside the louver, rather than a drive device outside the system louver. Therefore, there is no protrusion on the outside of the system louver, which is beautiful in appearance. In addition, in the conventional system louver, the mounting position of the driving device is limited to the upper side or the side of the louver, but in the present invention, the driving device is mounted inside the louver, so it may be mounted at a convenient place among the inside of the louver. As such, there is no restriction on the position of mounting the driving device, and it provides an automatic and manual system louver that is beautiful in appearance.

(Example)

The configuration and operation of the present invention will be described with reference to Figs.

1 is an overall configuration diagram of an automatic and manual system louver according to the present invention mounted inside the system louver. In addition, Figure 2 is a view showing in detail the assembly process for each component in FIG.

The automatic and manual system louvers of the present invention include a DC motor 103, a motor drive rotary shaft A115 receiving rotational force from the DC motor 103, motor drive rotary shafts B121a and 121b receiving a rotational force from the motor driving rotary shaft A115, and a motor in the automatic mode. The motor drive is connected to the mode changeover switch 118 and the mode changeover switch 118 which are operated so that the drive rotation shaft A115 and the motor drive rotation shaft B121a are engaged with each other so that the motor drive rotation shaft A115 and the motor drive rotation shaft B121a are released. It is mounted on the rotation support shaft 120 of the mode switching switch supporting the rotation shaft A115 and the motor drive rotation shaft B121a, and the motor drive rotation shaft A115 and the motor drive rotation shaft B121a are engaged with each other in the expanded state while the motor drive is in the contracted state. Unlocked shaft A115 and motor-driven shaft B121a The linear motion of the spring S acting as a motor, the fixed spur gear 127 and the louver rotating spur gear 128, and the louver rotating spur gear 128, which transmits the rotational force of the motor driving rotary shafts B121a and 121b to the drive connecting rotary arms 132 and 133, It is an automatic and manual system louver, which is composed of a drive connection rotary arm 132, 133, etc., which opens or closes the wing of the louver, and can open or close the wing of the system louver automatically and manually.

Here, the mode changeover switch 118 is employed to automatically and manually open or close the wing of the system louver. The operation of the mode switching switch 118 will now be described in detail.

In the automatic mode, as shown in Fig. 2, the mode changeover switch 118 is positioned on the left side of the mode changeover switch changeover hole 119 (usually selected as the automatic mode) so that the spring S is kept inflated, so that the motor drive shaft A115 The motor drive shaft B121a is engaged. Therefore, since the motor drive rotary shaft A115 and the motor drive rotary shaft B121a are rotated in engagement, the rotational force of the DC motor 103 is transmitted to the drive connecting rotary arms 132 and 133 via the motor drive rotary shaft A115 and the motor drive rotary shaft B121a. Can be opened or closed.

On the other hand, in the manual mode, as shown in Fig. 2, the mode changeover switch 118 is positioned to the right of the mode changeover switch changeover hole 119 and is fixed. In this state, since the spring S is contracted, the engagement between the motor drive rotation shaft A115 and the motor drive rotation shaft B121a falls. Therefore, even if the DC motor 103 rotates, the motor drive rotation shaft A115 is in the idle state, so that the rotational force of the DC motor 103 is not transmitted to the motor drive rotation shaft B121a. Therefore, the wing of the louver can be opened or closed by hand and can be opened or closed by the manual knob shown in FIG.

First, the operation of opening the wing of the louver in the automatic mode will be described in detail with reference to FIGS. 1 and 2.

When the release button (not shown in the figure) is pressed to open the vane of the system louver, power is applied to the DC motor 103 so that the DC motor 103 rotates in the forward direction. Since the rotation shaft of the DC motor 103 is connected to the reduction gear 104, and the rotation shaft of the reduction gear 104 is connected to the motor driving rotation shaft A115, the reduction gear 104 and the motor driving rotation shaft A115 rotate together in the forward direction by the forward rotation of the DC motor 103. In this case, since the reduction speed 104 of the DC motor itself is fast, it reduces the rotation speed and adjusts the speed at which the wing of the system louver opens.

By the forward rotation of the motor drive rotation shaft A115, the motor drive rotation shafts B121a, 121b meshed with the motor drive rotation shaft A115 rotate together in the forward direction. 3 and 4, the right end portion of the motor drive rotation shaft A115 and the left end portion of the motor drive rotation shaft B121a are formed in a step shape. As shown in Fig. 4, the motor drive rotation shafts B121a and 121b and the spring support 121c are integrally formed, and the spring support 121c serves to support the spring S mounted on the motor drive rotation shaft B121b. The spring S is mounted on the motor drive shaft B121b. In the automatic mode, the mode changeover switch 118 is located on the left side of the mode changeover switch changeover hole 119 (usually selected as the automatic mode), so that the spring S maintains an expanded state. That is, the motor drive rotation shaft A115 and the motor drive rotation shaft B121a are engaged by the elastic force of the spring S. Therefore, the rotational force of the DC motor 103 is transmitted to the motor driving rotary shafts B121a and 121b via the motor driving rotary shaft A115. In the present embodiment, the motor driving rotary shaft A115 and the motor driving rotary shaft B121a are formed in a stepped shape to show an engaged state or a disengaged state. However, the present invention is not limited thereto. good.

In addition, the forward rotational force of the motor drive rotation shaft B121b is transmitted to the fixed spur gear 127 and is also transmitted to the louver rotating spur gear 128 meshed with the fixed spur gear 127. Therefore, the fixed spur gear 127 and the louver rotating spur gear 128 rotate together in the forward direction by the forward rotational force of the motor drive shaft B121b.

Here, the fixed spur gear 127 of the motor drive rotation shaft B has a rectangular hole in the center thereof. The motor driving rotary shaft B121b is inserted into the square hole of the fixed spur gear to transmit the rotational force of the motor driving rotary shaft B121b to the fixed spur gear 127.

In addition, both sides of the louver rotating spur gear 128 are formed such that the driving connecting rotary arm A130 and the driving connecting rotary arm axis B131 protrude. In addition, the drive connecting rotary arm A130 and the drive connecting rotary arm B131 is connected to the drive connecting rotary arm A133 and the drive connecting rotary arm B132, respectively.

The drive connecting rotary arm A133 connected to the drive connecting rotary arm axis A130 moves downward by the forward rotation of the louver rotating spur gear 128, and the driving connecting rotary arm B132 connected to the drive connecting rotary arm axis B131 moves upward. That is, the drive connecting rotary arm shafts 130 and 131 change the rotational motion of the louver rotating spur gear 128 into linear motion. The louver wing cover 134 is opened by 90 degrees by the vertical movement of the drive connecting rotary arms 132 and 133, and thus the wing of the louver is opened by 90 degrees. By this operation, the wing of the louver is opened.

Next, the operation of closing the louver wings in the automatic mode will be described. The operation of closing the louver wing is simply the flow of operation because the rotation direction of the DC motor 103 is operated in the reverse direction in the opening operation of the louver wing.

When power is applied to the DC motor 103 by pressing the closing button (omitted in the figure), the motor drive shaft A115 rotates in the reverse direction by the reverse driving of the DC motor 103. The motor drive rotary shafts B121a and 121b, which are engaged with the motor drive rotary shaft A115, rotate together in the reverse direction by the reverse rotation of the motor drive rotary shaft A115, and the fixed spur gear 127 and the louver rotary spur gear 128 also rotate together in the reverse direction. The drive connecting rotary arm A133 connected to the drive connecting rotary arm A130 is moved upward by the reverse rotation of the louver rotating spur gear 128, and the driving connecting rotary arm B132 connected to the driving connecting rotary arm B131 moves downward. The louver wing cover 134 opened by the vertical movement of the drive connecting rotary arm 132, 133 is closed, so the wing of the louver is also closed. By this operation, the wing of the louver is closed.

Next, the operation of opening or closing the louver wing in the manual mode will be described.

As shown in Fig. 5, the change-over hole 119 of the mode changeover switch is formed in an L-shape. Move the mode selector switch 118 to the right and slide it backward to fix the manual mode. The lower portion of the mode changeover switch 118 is connected to the upper portion of the rotation support shaft 120 of the cylindrical mode changeover switch. Accordingly, when the mode changeover switch 118 is moved to the right and fixed, the mode changeover switch rotation shaft 120 and the motor drive rotation shafts B121a and 121b are pushed to the right to contract the spring S. At this time, the engagement between the motor drive rotation shaft A115 and the motor drive rotation shaft B121a is released. Therefore, the motor drive rotary shaft B121a is not affected by the rotational force from the motor drive rotary shaft A115, so that the motor drive rotary shaft B121a is not affected by the rotation of the motor drive rotary shaft A115. Therefore, the louver wing can be opened or closed by hand, or can be opened or closed by the manual knob shown in FIG.

In addition, since the driving device of the present invention uses a small DC motor, it is mounted inside the system louver. In Fig. 6, a portion for mounting the drive device of the present invention is shown at the lower right of the system louver. Therefore, although the driving device is mounted on the lower right side of the system louver in this embodiment, the present invention is not limited thereto and may be mounted anywhere in the system louver.

6 is a diagram showing various applications that can be applied to the automatic and manual louver systems of the present invention. The automatic and manual system louvers of the present invention can also be used in connection with a personal PC or Internet network or home automation. It can also be used by connecting to wind sensors, fire sensors, temperature sensors, or human sensors.

Automatic and manual system louvers of the present invention,

First, the automatic and manual system louvers of the present invention can freely open and close the louver manually in the interior of the louver not only when operating the system louver in the central control room but also in case of an emergency such as a power failure or a fire, so that ventilation or light There is no restriction on the back and there is an effect that can effectively respond to emergencies.

Secondly, the present invention uses a small DC motor as the driving means. Therefore, unlike a conventional system louver, a driving device is equipped with a small DC motor without using a cylinder or an AC motor as a driving means, so that the driving means can be miniaturized.

Third, the drive device of the present invention is mounted inside the system louver. Unlike a conventional system louver, the drive unit is mounted inside the louver, rather than a drive device outside the system louver. Therefore, there is no protrusion on the outside of the system louver, which is beautiful in appearance. In addition, in the conventional system louver, the mounting position of the driving device is limited to the upper side or the side of the louver, but in the present invention, the driving device is mounted inside the louver, so it may be mounted at a convenient place among the inside of the louver.

Also, in terms of economics, the reality of relying on complete system louvers of foreign products adopting AC motors (roll screen motors) for almost all demands of the domestic market, or importing, assembling and producing most of the main parts including AC motors. Considering this, the effect is remarkable.
