Description

{Modular vent assembly for building frame mounting}

The present invention relates to a modular ventilation structure, and more specifically, to a modular ventilation structure for installation on a building frame, which is manufactured and installed in a modular manner so that it can be installed on any part of a building frame, such as the upper part, lower part, or vertical member of a building frame, such as a double-glazed window or a double-skin curtain wall, to induce ventilation while ensuring airtightness and watertightness and preventing condensation around windows.

In general, if the indoor ventilation and air circulation of a building is not smooth, air pollution accelerates over time due to various harmful substances emitted from indoor building materials or cooking, as well as an increase in dust, fine particles, and microorganisms in the air, which causes harmful effects to the human body. Therefore, it is important to periodically ventilate the indoor and outdoor air to prevent various pollutants from accumulating indoors.

The traditional ventilation method is to open the windows, but recently, in high-rise buildings or residential buildings, the installation of openable windows is often omitted for safety reasons and forced ventilation systems are applied. In this case, since normal functioning is not possible due to unexpected situations such as power outages or ventilation device failures, a method is required to bring in outdoor air and exhaust indoor air using natural ventilation.

In particular, since ventilation is based on the premise of indoor and outdoor air flow, there is a high risk that the ventilation structure will become a weak point in insulation in winter when the indoor and outdoor temperature difference is large, and condensation may occur in the surrounding area. In addition, a method that can effectively block the inflow of external air pollutants such as fine dust, yellow dust, and pollen, as well as insects, is required.

The above hinge part (3) is configured to connect the body (1) and the opening/closing part (2) to enable rotation of the opening/closing part (2). In the embodiment of the present invention, a friction damper structure is applied to implement semi-automatic low-speed opening/closing, thereby improving user convenience. In addition, a soft opening hinge, a damper hinge, a slam latch, or other structures may be applied to enable semi-automatic low-speed opening/closing of the opening/closing part.

In addition, the hinge part (3) is basically connected through the rotation part (33) in the middle portion to rotate around this axis, and is composed of a first hinge part (31) with a first coupling hole (311) formed on one side and a second hinge part (32) with a second coupling hole (321) formed on the other side, so that the angle between them can be adjusted and they are fixed to the opening/closing part (2) and the body (1), respectively.

That is, the first hinge part (31) is fixed to the opening/closing part (2), and the second hinge part (32) is fixed to the body (1), respectively. Specifically, the opening/closing part (2) is configured with a cover part (241) that receives the first hinge part (31) on the other side, covers the first hinge part (31) so that it is not visible from above, and extends beyond the position of the rotating part (33), and a first connecting part (24) formed with an inner support part (242) that contacts the first hinge part (31) from below with the first hinge part (31) interposed therebetween, communicates with the first connecting hole (311), and has a first connecting hole (243) into which a flat head bolt (7) is inserted.

As mentioned, the present invention can secure economic feasibility by manufacturing it as an individual module unit, thereby making it easy to apply it to existing frames and newly designed frames, and can be configured to be installed in any part of the frame, such as the upper part, lower part, or vertical member. In the attached drawing, the convection performance can be improved by installing it in the lower and upper parts respectively, so that the lower unit brings in cold air and the upper unit discharges hot air.

In Fig. 6, a structure installed between the inner and outer glass of a double-glazed window and a double-skin curtain wall is shown, with (a) being in a closed state, (b) being in a semi-open state, and (c) being in a fully open state, respectively, and can prevent indoor air pollution and condensation around windows by inducing constant ventilation and rapid ventilation.

FIG. 9 is a first side cross-sectional view according to a modified embodiment of the present invention, and FIG. 10 is a second side cross-sectional view according to a modified embodiment of the present invention. In the modified embodiment of the present invention, a structure is provided to ensure airtightness of the gap between the upper surface of the body (1) and the opening/closing portion (2).

As mentioned, in order to ensure smooth opening and closing of the opening part (2), a gap must exist between the upper side of the body (1) and the opening part (2), and in particular, the gap on the other side where the hinge part (3) is located cannot help but widen further during the opening and closing process.

To this end, in a modified embodiment of the present invention, a second blocking member (27), which is an elastic sealing member that is installed along the edge of the opening/closing member (2) and can close the gap between the bodies at the same time, is installed on the side where the hinge part (3) is located, that is, the other three sides of the rectangular shape based on the plan view, except for the side where the hinge part (3) is located, and a flexible plate-shaped first blocking member (26) is installed on the side where the hinge part (3) is located, thereby providing a double sealing structure between the opening/closing member (2) and the body (1).

Specifically, in the support portion on the other side of the body (1), a protrusion (14) that protrudes toward the receiving space (153) is formed, and a first blocking member (26) that blocks the gap between the end of the cover portion (241) and the protrusion (14) is installed, so that the first blocking member (26) bends along with the opening and closing of the opening/closing portion (2) and can constantly block the gap above the receiving space (153). At this time, it is preferable that the other end of the first blocking member (26) be configured in a downwardly curved shape so that it can contact the lower side of the protrusion (14).

To this end, in a modified embodiment of the present invention, a receiving groove (25) is formed to receive the first blocking member (26) so as to slide downwardly on the cover portion (241), so that when the opening/closing portion (2) is opened, the first blocking member (26) enters the receiving groove (25), and when the opening/closing portion (2) is closed, the first blocking member (26) is installed so that it can come out of the receiving groove (25), and the entirety or a portion of the first blocking member (26) is made of a material that reacts to magnetism, and a magnetic body (16) to which the other end of the first blocking member (26) can be attached and supported when the opening/closing portion (2) is closed is installed on the protruding projection (14).

At this time, the magnetic body (16) is selected to have an appropriate magnetic strength so that it maintains an adhesive force with the first blocking member (26) when the opening/closing part (2) is closed, but the first blocking member (26) can be smoothly separated by an external force applied through the cover part (241) when the opening/closing part (2) is opened.

In addition, in the process of covering the opening/closing portion (2), an elastic body, specifically an elastic wire (28) having a circular, oval or curved shape, may be installed inside the opening/closing portion (25) to push the first blocking member (26) outward so that the first blocking member (26) can smoothly come out of the receiving groove (25). Through this, even if the magnetic body (16) is not present, when the opening/closing portion (2) is opened, the first blocking member (26) is pushed inward into the receiving groove (25), the elastic wire (28) is pressed and force is accumulated, and when the opening/closing portion (2) is covered, the first blocking member (26) is pushed outward by the restoring force of the elastic wire (28) and the state of contact with the lower side of the protruding projection (14) is maintained, so that a smooth airtight structure can be formed.

Through this structure, the performance equivalent to that of a project window is realized through the contact between the gasket (4) and the sealing member (21) described above, as well as the double sealing structure through the first blocking member (26) and the second blocking member (27), and condensation around the window is effectively prevented.

The rights of the present invention are not limited to the embodiments described above, but are defined by what is described in the claims, and it is obvious that a person skilled in the art in the field of the present invention can make various modifications and adaptations within the scope of the rights described in the claims.
