Referring to FIGS. 1 to 4, a preferred embodiment of the present invention provides a window frame, which is used to fit over an old window frame 10 as shown in FIG. 4. The window frame of the present invention includes a pair of side frames 100, an upper frame 200 and a bottom frame 300 connected between the pair of side frames 100. The pair of side frames 100 are parallel and spaced apart from each other, the upper frame 200 and the bottom frame 300 are parallel and spaced apart from each other, and the upper frame 200 and the bottom frame 300 are arranged perpendicular to the pair of side frames 100.

Each side frame 100 is elongated, and in this embodiment, each side frame 100 is preferably a plate body arranged upright, but the invention is not limited to the plate body. The upper frame 200 and the bottom frame 300 are horizontal columns, respectively.

Specifically, the two ends of the bottom frame 300 are connected to one side of each side frame 100 respectively. The two opposite sides of the bottom frame 300 are respectively provided with a front side plate 310 and a rear side plate 320 between the front side plate 310 and the rear side plate 320 A sleeve socket 301 is formed around the bottom frame 300, and a rail 330 on the opposite side of the sleeve socket 301 is provided on the bottom frame 300. A hollow portion 101 is formed at the corresponding position of the pair of side frames 100 and the socket groove 301, wherein the outline of the hollow portion 101 of each side frame 100 corresponds to the cross-sectional contour of the socket groove 301. In this embodiment, preferably, the height of the front side plate 310 is lower than the height of the rear side plate 320, the depth of the socket groove 301 on the side adjacent to the front side plate 310 is shallower than the depth on the side adjacent to the rear side plate 320, and is stepped shape. Therefore, the cross-sectional profile of the socket groove 301 can correspond to the outer sash track 11 with a stepped outer lower inner height. In addition, the outline of the hollow portion 101 of each side frame 100 also corresponds to the socket groove 301 in a stepped shape with an outer lower inner height.

A waterproof sheet 400 is interposed between the two ends of the bottom frame 300 and each side frame 100, and each waterproof sheet 400 preferably covers the two ends of the bottom frame 300 respectively, and each waterproof sheet 400 is formed by cutting corresponding to the sleeve groove 301 There is an inscribed edge 401 and the pair of inscribed edges 401 is preferably located between the front side plate 310 and the rear side plate 320.

Referring to FIG. 4, when the window frame of the present invention is installed, it is sleeved on an old window frame 10. The window frame of the present invention is placed obliquely into the old window frame 10, and the bottom frame 300 is first placed into the old window frame 10, and the old window frame track 11 is accommodated in the socket groove 301 under the bottom frame 300. The pair of inscribed edges 401 of the waterproof sheet 400 of the window frame can pass through the old window frame track 11, thus avoiding the structural interference between the waterproof sheet 400 and the old window frame track 11 causing the waterproof sheet 400 to be pulled and displaced or deformed. Cause waterproofing to fail. Therefore, the window frame of the present invention can prevent the seal from being damaged during the installation process. Then, the window frame of the present invention is upright and moved entirely into the old window frame 10 and the upper frame 200 covers the top inner edge of the old window frame 10. Therefore, the window frame of the present invention can be fitted with the old window frame 10 instead of the old window frame 10.
