Description

Missing window structure {SLIDING WINDOW STRUCTURE}

The present invention relates to the structure of the misocean.

In general, a window is a general term for a window frame installed on a wall of a building and a window frame installed on the window frame. A window performs several functions, such as a function to block heat transfer between indoors and outdoors, a function to block outdoor noise, and a function to prevent outdoor water from flowing into the room.

Therefore, in order to prevent heat loss and increase sound insulation, airtightness must be secured, and drainage to the outdoors must be smoothly performed to prevent outdoor water from flowing into the room.

In the case of windows generally used in buildings, depending on the opening and closing method, they can be classified into non-seogi windows or hinged windows.

Miseogi (sliding) windows and windows are shaped like windows that move left and right on rails. Miseogi windows maintain airtightness by inserting mohair in a space spaced between the lower part of the window and the rail, but it is impossible to completely seal the gap, so airtightness is not good, and there is a problem that the opening and closing force is lowered due to friction with the mohair have.

Tilt & Turn system windows have the advantage of excellent airtightness as the window frame and the window sill are completely in close contact using special hardware (hardware), but space utilization is limited due to the structure that opens inside.

In order to solve this problem, technologies related to windows with improved airtightness are being developed by moving a window that opens and closes in a direction perpendicular to the direction of the linear reciprocation movement while making a linear reciprocating motion along the rail provided on the window frame and completely adheres to the window frame. .

However, in this prior art, there is a problem in that the drainage capacity for smooth drainage is not sufficiently secured, so that outdoor water may leak into the interior, and there is still a concern that water may accumulate in the window frame.

In another example, the structure of the Miseogi window may further include a first gasket inserted into the first insertion part of the auxiliary cover, the first gasket being formed so as to be in contact with the window in a closed state in which the window is moved to the outside. .

In another example, the Miseogi window structure is formed to be inclined downward on the outdoor side, and is inserted into a second insertion portion formed below the first insertion portion, and introduced through a gap between the first gasket and the windowpane. It may further include a second gasket that is provided to guide the flow of water downward on the outdoor side, and is formed to be in contact with the window sill in the closed state.

In another example, the auxiliary cover may include a first through hole through which the auxiliary cover is formed so that water can be introduced, and the first through hole may include a space between the first gasket and the second gasket. It may communicate with the first space and the fixing window groove.

In another example, the window frame may further include a first drainage channel formed in communication with the fixed window groove and the outdoors, and guiding the water flowing into the first through hole to be discharged to the outdoors.

In another example, the window frame may further include a second drainage passage located below the first drain passage and formed in communication with a second space that is a space between the second gasket and the window frame and outdoors.

In another example, the window frame is located on the indoor side of the second drain, and is recessed downward to store water overflowing from the second drain, and discharges water introduced into the fresh water space and the fresh water space to the outdoors To do so, it may further include a third drainage channel formed in communication with the fresh water space and the outdoors.

In another example, the changjak is formed through the changjjak so that the water introduced into the changjjak passes and is guided to the window frame, and communicates with the changjjak groove into which the second space and the windowpane of the changjjak are inserted. It may further include two through-holes.

In another example, the changjak is formed to protrude downward from the outdoor side of the changjjak, and includes a water cut-off part having a lower surface inclined downward on the outdoor side of the changjjak, and the water cut-off part, A first water cut-off part for landing with the first gasket and the first water cut-off part are located indoors lower than the first water cut-off part, and the water introduced through the gap between the first gasket and the window sill is landed with the second gasket.
