Inner frame for door or window, skylight comprising the same and manufacturing method thereof
View Patent ↗An inner frame of a door or a window is disclosed. The inner frame is disposed at an inner side of a window sash, and is connected between a jamb of the door or the window sash and a door frame or a window frame. The inner frame includes a fixing portion for fixing to the jamb, a water baffle, and a connecting portion for connecting with the door frame or the window frame. One side of the fixing portion is fixed to the jamb, the water baffle is integrally disposed on the other side of the fixing portion opposite to the one side, and the connecting portion is integrally disposed on a side of the water baffle facing away from the fixing portion and is connected to the door frame or the window frame.
1. A skylight, comprising an outer profile frame, an inner profile frame, a window frame, and a glass plate disposed between the outer profile frame and the inner profile frame, wherein the skylight is mounted on a roof through the window frame, the outer profile frame is formed by splicing a plurality of outer profiles, a first fixing piece is disposed on an inner side surface of the outer profile frame, the inner profile frame comprises an annular water blocking portion disposed along the outer profile frame, the annular water blocking portion is formed by bending a water baffle, a junction of ends of the water baffle directly faces any of the plurality of outer profiles, an outer side surface of the annular water blocking portion is disposed with a second fixing piece, and the first fixing piece is in snap-fit engagement with the second fixing piece.
2. The skylight according to claim 1 , wherein a connecting portion is disposed at one side of the water baffle away from the second fixing piece, and a bottom of the water baffle protrudes from a lower surface of the connecting portion.
3. The skylight according to claim 2 , wherein when the skylight is closed, a lower end surface of the water baffle is lower than an upper end surface of the window frame.
4. The skylight according to claim 3 , wherein the water baffle is provided with a first seal abutting against the glass plate, and the window frame is provided with a second seal abutting against the connecting portion.
5. The skylight according to claim 2 , further comprising a mullion, wherein the mullion is mounted on the water baffle via the connecting portion.
6. The skylight according to claim 1 , wherein a gap is left between adjacent second fixing pieces.
7. The skylight according to claim 1 , wherein a heat insulating strip is provided between the second fixing piece and the first fixing piece.
8. The skylight according to claim 7 , wherein a surface of the second fixing piece is provided with a sliding rail, and the heat insulating strip is slidably connected to the sliding rail.
9. A method for manufacturing a skylight, the method comprising the following steps
step S1, processing an outer profile, including cutting two ends of the outer profile, so that a plurality of outer profiles are configured to be spliced into an outer profile frame, an inner side surface of the outer profile frame is integrally formed with a first fixing piece;
step S2, processing an inner profile, including cutting off a second fixing piece at a portion of a water baffle to be bent, and cutting a connecting portion at the portion of the water baffle to be bent, so that the connecting portion is configured to be spliced into a shape matched with an inner profile frame after bending the water baffle;
step S3, shaping the inner profile frame, including bending the water baffle to make two ends of the water baffle abut against each other, and mounting a first seal on the water baffle; and
step S4, assembling, including placing the inner profile frame on an operation table, placing a glass plate on the inner profile frame, and then inserting the outer profile from a side surface of the inner profile frame and the glass plate, so that the second fixing piece is snap-fitted into the first fixing piece.
10. The method of manufacturing the skylight according to claim 9 , wherein:
before the step S4, providing a heat insulating strip between the second fixing piece and the first fixing piece; and in the step S4, inserting a corner brace between two adjacent outer profiles of the plurality of outer profiles, and the two adjacent outer profiles are abutted against the corner brace by a compression device.
