Description

Electromagnetic louver opening and shutting apparatus

The present invention relates to an electric louver opening and closing device, and more specifically, has a compact electric structure utilizing the internal space of the louver's exterior frame to the maximum, and the mechanism is not exposed from the outside, and the louver can be easily operated at various angles from a long distance. It relates to an electric louver switchgear that can open and close the door.

In general, louvers are arranged horizontally at regular intervals at narrow intervals of narrow plates, also called barbs or barbs in construction, mining, artificial lighting, daylighting, ventilation It is used for the purpose of ventilation. For ventilation or ventilation, it is common to hit the louvers due to the seepage of rainwater, but it is not always necessary to use louvers when used for daylighting, artificial lighting or daylight adjustment. In other words, it is possible to select a variety of types by applying these modifications to the horizontal, vertical or lattice windows.

When used with respect to light, the light source surface is not so bright, only the working surface can be brightened, the light beam is directed, and the light intensity can be made uniform so that the illuminance distribution in the room can be uniform, and direct sunlight can be used in winter. You can adjust the sun's sunshine by letting it enter the room during the summer and blocking it during the summer.

Therefore, while the louver meets the above conditions, the interior does not look inside, and the interior does not have any inconvenience in looking out.

This type of louver is commonly used in ventilation windows, so it can be called ventilation windows, which are installed for the purpose of ventilation in the veranda of the apartment, the machine room of the rooftop of the apartment, and recently, the outdoor unit of the air conditioner installed in the commercial building of the residential complex. Ventilation windows, etc. are being installed in order to cover the exposure of the building out of the building.

Such a ventilation window is configured to form a rectangular frame by connecting the rectangular frame to the upper and lower sides and left and right, and these frames are installed to be fixed so as not to move by being inserted into the hole of the building wall. Among these frames, a plurality of louvers rotated on the frame facing surfaces on the left and right sides are provided. These louvers are placed in a straight line so that the adjacent louvers and the upper and lower ends overlap, and the ventilation windows are closed, and when they are rotated in a horizontal state, the ventilation windows are opened and opened.

Conventionally, there was no opening / closing angle adjusting device for ventilating windows to guide the horizontal and vertical states of the louvers in the ventilating windows, and they were connected to the louver holders in the louver at one end of the louver aligned by the louver holders. The adjustment was made by dividing the opening or closing of the louver by the lever protruding outward.

However, the ventilation window that is opened and closed by the conventional lever has a problem that the wear of the hinge portion in the frequently used process causes a member of the operating state that is opened and closed when opened.

In addition, there is no support structure of the lever, and the setting of the required opening and closing angle becomes inaccurate, and even when it is closed, the adhesion of the louver decreases so that it cannot be completely sealed. The cooling and heating efficiency of the room is significantly reduced, and there was a problem such that noise outside the room is also introduced into the room.

In order to solve this conventional problem, the louver is formed to be rotated about the center pivot axis, and one side frame is formed with an adjustment knob for rotating the louvers simultaneously, and the adjustment knob is a desired state for each louver according to the angle. An angle adjusting groove is formed so that the adjustment knob and each louver are connected to each other through a link, and a louver angle adjusting device of the ventilation window has been proposed, but the semicircle plate formed with a plurality of angle adjusting grooves is provided with an adjustment knob. Likewise, as it is formed to protrude into the inside of the ventilation window, there is a problem that there is a risk of injury when contacting body parts such as hands, back of hands, arms, etc. by inadvertent fall.

In addition, the mechanical volume including the adjustment knob exposed to the outside of the louver is large, the operating range is also wide, requires a lot of space, there is a safety problem because the operation is exposed. And, because it is manufactured by hand to open or close, because the person directly moves the control knob to move up and down, when installed in a high place, there was a problem that you need to use a long rod or climb a structure such as a ladder.

In addition, there is a conventional technique that performs the opening and closing operation of the louver simply by the forward and backward movement of the shaft having a forward and backward stroke in the form of a cylinder to the lever of a lever for manual operation. It is installed on the side, which is not good in appearance and has a safety problem. The cylinder shaft is moved left and right by the flow of the handle, and occupies the top volume of the space, and the joint between the lever and the cylinder shaft is also clean. There were many problems with the overall appearance.

In other words, the coupling with the cylinder shaft is made at the end of the handle, and the cylinder is also raised and lowered by the rotation radius of the handle, and the length of the cylinder is also increased due to the large stroke of the shaft and the need to store the shaft inside the cylinder. , The volume occupied by the mechanical operating part in the state that the shaft is missing has a problem that at least twice the operating stroke is required.

The present invention is to solve the conventional problems as described above, by utilizing the internal space of the louver's exterior frame to the maximum has a compact transmission structure and the operating mechanism is not exposed from the outside and easily at various angles from a distance The purpose is to provide an electric louver opening and closing device that can open and close the.
