Description

[Detailed Description of the Invention] This invention relates to a window snow damage protection screen device whose main purpose is to prevent snow damage such as breakage of window glass due to snow accumulation, especially in cold regions.

Conventionally, as a means to prevent damage to window glass due to snow accumulation, a so-called snow fence, which consists of a frame of wood or the like built between the eaves and the ground, and a board attached to the iron frame, has been commonly used. Since the outside of the window is covered with a board, it becomes dark indoors,
Moreover, it had the disadvantage of poor appearance.

The window snow damage protection screen device of the present invention eliminates the drawbacks of the conventional one, and embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is an aluminum sash window frame fixed to the frame F, consisting of upper and lower horizontal frames 2 and 3 and left and right vertical frames 4 and 5, and the outdoor side ends of the upper and lower horizontal frames 2 and 3. An upper rail groove 6 and a lower rail groove 7 are respectively formed in the upper and lower rail grooves, and a protective screen 30 is supported in the upper and lower rail grooves.

The protective screen 30 has a frame 8 consisting of upper and lower horizontal frames 10, 11 and left and right vertical frames 12, 13 of aluminum sash having a fitting groove 9. The four sides of the impact synthetic resin plate 14 are fitted through glazing beads 15.

The synthetic resin plate 14 is made of polycarbonate resin, polybutylene terephthalate resin, polyacetal resin, FR
P etc. are used.

Upper and lower sleeve plates 16 and 17 and left and right sleeve plates 18 and 19 are extended from the indoor end of the protective screen frame 8, respectively, and elongated holes 20 formed in the upper and lower sleeve plates 16 and 17 are respectively extended. Pass through the screw 21, screw the clamping piece 22 having a bifurcated clamping part onto the screw 21, and attach the window and the right vertical frame 12, 13 to the left side of the window frame 1 and the outdoor side surface of the right vertical frame 4, 5. The outdoor side walls 24 and 25 of the upper and lower rail grooves 6 and 7 are pressed and clamped between the two prongs of the clamping piece 22 via the backing 23.

To remove the protective screen 30 from the window frame 1, use screws 2
Loosen 1.21 and attach the clamping piece 22.22 to the side wall 24.25.
Then, the upper and lower sleeve plates 16 and 17 can be removed from the upper and lower rail grooves 6 and 7.

26 is a handle of the protective screen frame 8, and 27 is a window shoji.

When attaching the protective screen 30 of the present invention to a wooden window frame, insert wood screws through the long holes 20.20 of the upper and lower sleeve plates 16.17 and the through holes 28.28 of the left and right sleeve plates 18, 19, respectively, to the wooden window frame. It is removably screwed onto the

The snow damage protection screen device for windows of this invention has a structure in which a protective screen made of a transparent or translucent impact-resistant synthetic resin plate fitted into a frame is attached to the outdoor side of the window so as to cover the entire outdoor side of the window. Even if snow accumulates outside the window in a cold region, the impact-resistant synthetic resin board blocks the snow and prevents accidents such as damage to the window glass. There is almost no obstruction to daylight coming in, keeping the interior bright and the exterior looking good.Furthermore, it has a structure similar to double-glazed windows.
Since there is a space between the protective screen and the window, it has an insulating effect, increasing the heat retention of the window and saving heating costs.The protective screen is also removable, so it does not need to be attached to the window frame. It is easy to install and remove, and when it is not snowing, the protective screen can be removed and used as a regular window, and when snow protection is not needed, such as in the summer, it can be removed from the window frame, and then a screen can be fitted into the lower rail groove. It can also be incorporated, and is extremely effective in practice.
