Louver including a shutter blade closure cap with improved insulation performance {ROUVER WITH SHUTTER BLADE CLOSING CAP HAVING IMPROVED INSULATION PERFOMANCE}

The present invention relates to a louver including a shutter blade finish cap with improved thermal insulation performance.

Ventilation windows are used to ventilate indoor air, such as in buildings or factories, by discharging the turbid air to the outside and allowing fresh air from the outside to naturally enter the room.

In apartment buildings, which are residential buildings, the airtightness of the curtain wall skin is strengthened and the area of ventilation windows is small, so ventilation-related problems that were not considered in the past are occurring. Problems of decreased indoor air quality, overheating, and increased building energy use due to dependence on mechanical forced ventilation are emerging.

The need for natural ventilation to improve this is increasing, and natural ventilation efficiency must be increased through reasonable ventilation windows in apartments.

Ventilation windows provided on the interior and exterior walls of buildings or factories have multiple blades connected and fixed to the frame at a certain angle. In this case, a certain gap is formed between each blade, and the indoor side has a higher inclination angle than the outdoor side. It is used as a ventilation window for the inflow of outdoor air and the exhaustion of indoor air, while preventing the interior from being viewed from the outside.

Meanwhile, as a prior document for ventilation of buildings, factories, etc., Republic of Korea Patent No. 10-0966170 discloses “Shutter opening and closing device for ventilation windows.”

The ventilation window opening and closing device according to the prior art is a ventilation opening (1) that is joined by contacting both ends of a pair of horizontal frames (2a) and a vertical frame (2b), and a rotating blade (3b) is rotated inside the ventilation opening (1). A shutter unit (3) formed in multiple stages that can be opened and closed is formed on the inside of the vertical frame (2b), and the shutter holder (3c) of the shutter unit (3) is inserted into the center of one side and rotates to form the shutter unit (3). A rotary link (4) in which the rotary blades (3b) open and close simultaneously, a lifting unit (6) that is integrally fixed to the other side of the rotary link (4) and connects the rotary motion to linear motion, and one rotary link (4) An adjustment lever (8a) is mounted on the front of the vertical frame (2b) to rotate the shutter unit (3) equipped with a rotating blade (3b) when it protrudes and rotates, and is adjusted to the center on the front of the vertical frame (2b). A locking guide member (7) in which the lever (8a) is loaded and has locking grooves formed in multiple stages on the protruding surface in the form of a semicircular arc, and a rocker (8c) having a locking protrusion variably hooked on the distal end of the protruding control lever (8a) and each locking groove. ) It consists of a locking unit (8) consisting of handles (8b) each loaded with a coil spring that supports the lower end of the rocker (8c) and simultaneously releases the rocker (8c).

As they are combined, the plurality of shutter blades 105 may be rotated in conjunction with each other.

As described above, according to one embodiment of the present invention, the airtight member s made of a soft material is coated on the portion of the frame 103 and the shutter blade finishing cap 107 that are in close contact with each other, thereby forming the frame 103. There is an effect of effectively reducing the fluid flowing between the and shutter blade finishing cap 107 compared to the prior art.

In addition, according to one embodiment of the present invention, the rotation support protrusion 407 is formed on the shutter blade finishing cap 107, thereby separating the frame 103 and the shutter blade finishing cap 107 at a certain distance from the frame 103. There is an effect in that the shutter blade finishing cap 107 can be easily rotated.

In addition, according to one embodiment of the present invention, the insertion protrusion 419 and the support cover 421 are formed on the shutter blade finishing cap 107 to close the gap s1 between the frame 103 and the shutter blade 105. It has the effect of significantly reducing the fluid flowing in through it, thereby improving insulation performance and airtightness performance.

In the above, even though all the components constituting the embodiment of the present invention have been described as being combined or operated in combination, the present invention is not necessarily limited to this embodiment. That is, as long as it is within the scope of the purpose of the present invention, all of the components may be operated by selectively combining one or more of them.

In addition, terms such as “include,” “comprise,” or “have” as used above mean that the corresponding component may be included unless specifically stated to the contrary, so excluding other components is not necessary. Rather, it should be interpreted as being able to include other components. All terms, including technical or scientific terms, have the same meaning as generally understood by a person of ordinary skill in the technical field to which the present invention pertains, unless otherwise defined. Commonly used terms, such as terms defined in a dictionary, should be interpreted as consistent with the contextual meaning of the related technology, and should not be interpreted in an idealized or overly formal sense unless explicitly defined in the present invention.

The above description is merely an illustrative explanation of the technical idea of the present invention, and various modifications and variations will be possible to those skilled in the art without departing from the essential characteristics of the present invention.

Accordingly, the embodiments disclosed in the present invention are not intended to limit the technical idea of the present invention, but are for illustrative purposes, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention shall be interpreted in accordance with the claims below, and all technical ideas within the equivalent scope shall be construed as being included in the scope of rights of the present invention.
