Anti-corner-falling window sash and movable window

Abstract

The invention provides an anti-corner-falling window sash and a movable window. The anti-corner-falling window sash comprises a window sash frame, a window sash assembly and an anti-corner-falling cushion block; the window sash assembly comprises window glass, and the window sash frame is provided with a connecting side window sash frame vertical profile used for being connected with a window frame and a lower window sash frame transverse profile located below the window glass; the anti-corner-falling cushion block is arranged at the splicing position of the connecting side window sash frame vertical profile and the lower window sash frame transverse profile and comprises a vertically-extending cushion block fixing part and a transversely-extending cushion block supporting part, the cushion block fixing part is fixedly connected with the connecting side window sash frame vertical profile, and the cushion block supporting part is in contact fit with the lower end of the window glass and is suspended above the lower window sash frame transverse profile. By means of the anti-corner-falling cushion block, a main stress point, borne by window glass, of the window sash frame is changed from an original lower window sash frame transverse profile to an existing connecting side window sash frame vertical profile, deformation of the lower window sash frame transverse profile is avoided, and finally the corner falling phenomenon of the lower window sash frame transverse profile in the vertical direction is avoided.

Description

technical field [0001] The invention relates to the field of doors and windows, in particular to an anti-dropping corner sash and a movable window comprising the corner-dropping preventing sash. Background technique [0002] Existing movable window comprises the window frame that is fixedly installed in the opening position of body of building wall, and the window sash that can open and close be installed in window frame; figure 1 As shown, the window sash has a sash frame 10 and a sash assembly 20 installed in the sash frame 10 , and the sash assembly 20 includes a window glass 21 . Generally speaking, the sash frame 10 of the window sash is rotatably mounted on the window frame through the hinge 60, so that the sash can be opened and closed relative to the window frame. [0003] Such as figure 1 As shown, the sash frame 10 has a pair of vertically extending sash frame vertical profiles 11 and a pair of laterally extending sash frame cross profiles 12 . A pair of sash fr...

AI Technical Summary

Problems solved by technology

[0005] Along with the continuous development of window technology, the specifications of windows gradually increase, resulting in the size of the sash frame 10 and the window glass 21 in the sash becoming larger and larger, and the weight of the corresponding window glass 21 is also getting heavier, thus making the above structure The movable window has the following defects: after the large-sized window glass 21 is installed, the lower sash frame cross section 121 directly bears the gravity of the window glass 21, and the heavier window glass 21 can easily cause the lower sash frame cross section 121 to deform. Thereby causing the lower sash frame horizontal profile 121 to drop corners along the vertical direction, such as figure 2 As shown, it is very difficult to operate when the sash is opened and closed
