Description

Technical Field

[0001] The present invention relates to the technical field of doors and windows, and in particular to a window wind brace and a window comprising the window wind brace. Background Art

[0002] The existing window mainly includes a fixed outer frame, a window sash assembled in the fixed outer frame, and a window wind brace. The window wind brace mainly includes a guide rail arranged on the fixed outer frame or the window sash, a slider arranged in the guide rail slide groove and slidable along the length direction of the guide rail, and a connecting rod with one end rotatably connected to the window sash or the fixed outer frame and the other end rotatably connected to the slider. When the window sash is opened or closed, the window sash drives the slider to slide in the guide rail slide groove, so that the wind brace can adapt to different opening angles of the window sash.

[0003] If the force required to open and close the window sash is very small, the window sash will move when it is open, which makes it difficult to maintain the window sash at the required opening angle. On the other hand, when encountering strong winds, the strong wind will push the window sash to hit the fixed window frame with great force, causing danger. Therefore, an adjustment mechanism is provided on the slider of some window wind supports, through which the friction between the slider and the guide rail can be adjusted, thereby adjusting the force required to open and close the window sash, so that the force required to open and close the window sash is maintained at an appropriate size. The specific structure of the adjustment mechanism is: it includes a base, a friction pad arranged on the base, and an adjustment component arranged in the friction pad and rotatably connected to the base. The friction pad can be elastically deformed and is located between the two inner side walls of the slide groove. By rotating the adjustment component, the pressure between the friction pad and the inner side wall of the slide groove can be changed, and the friction between the slider and the guide rail when the slider slides in the guide rail can be changed. In the above-mentioned adjustment mechanism, since the outer contour of the adjustment component has a sharp edge, the adjustment component will cut the friction pad when it contacts the friction pad, causing the friction pad to wear and the adjustment function to decrease. Summary of the invention

[0004] In view of the shortcomings of the prior art mentioned above, the technical problem to be solved by the present invention is to provide a window wind support, which can maintain the force required for opening and closing the window sash at an appropriate size, while effectively reducing the wear of the friction pad, ensuring the adjustment function of the adjustment mechanism, and improving the service life and operability of the adjustment mechanism.

[0005] To achieve the above-mentioned purpose, the present invention provides a window wind support, including a guide rail, a slider arranged in a slide groove of the guide rail and capable of sliding along the length direction of the guide rail, and a connecting rod rotatably connected to the slider, the slider is provided with an adjustment mechanism, the adjustment mechanism includes a base, an annular friction pad arranged on the base, and an adjustment component arranged in the friction pad and rotatably connected to the base, the friction pad can be elastically deformed and is located between the two inner side walls of the slide groove, the outer side surface of the adjustment component is a smooth curved surface, and the adjustment component can press the friction pad against the two inner side walls of the slide groove by rotating the adjustment component.

[0006] In the above-mentioned window wind support, by rotating the adjusting component, the adjusting component can press the friction pad against the two inner side walls of the slide slot, thereby adjusting the pressure between the friction pad and the two inner side walls of the slide slot, and also adjusting the friction between the slider and the guide rail when the slider slides in the guide rail, that is, adjusting the force required for opening and closing the window sash, so that the force required for opening and closing the window sash is maintained at an appropriate size. At the same time, since the outer side surface of the adjusting component is a smooth curved surface, it is possible to avoid cutting the friction pad when the adjusting component contacts with the friction pad, effectively reducing the wear of the friction pad, ensuring the adjustment function of the adjustment mechanism, and increasing the service life of the adjustment mechanism.

[0007] Furthermore, the outer side surface of the adjusting component is formed into an ellipse, and the sum of the long diameter of the ellipse and the thickness of the two side walls of the friction pad arranged oppositely along the width direction of the slider is greater than the distance between the two inner side walls of the slide. Since the outer side surface of the adjusting component is formed into an ellipse, when the adjusting component is rotated, the adjusting component can smoothly contact the friction pad, effectively reducing the wear of the friction pad. At the same time, since the sum of the long diameter of the ellipse and the thickness of the two side walls of the friction pad arranged oppositely along the width direction of the slider is greater than the distance between the two inner side walls of the slide, it can be ensured that sufficient friction is generated between the friction pad and the two inner side walls of the slide.

[0008] Furthermore, the adjusting member can rotate in both clockwise and counterclockwise directions, thereby improving the operability of the adjusting mechanism.

[0009] Furthermore, the adjustment mechanism further comprises a disc spring, and the disc spring is located between the base and the adjustment component. By arranging the disc spring between the base and the adjustment component, the gap between the base and the adjustment component can be absorbed, so that the adjustment component will not loosen, thereby improving the operability of the adjustment mechanism.

[0010] Furthermore, the upper surface of the adjusting component is provided with an adjusting hole, and the shape of the adjusting hole is preferably hexagonal or straight. In this way, it is convenient to insert a tool such as a screwdriver matching the shape of the adjusting hole into the adjusting hole to drive the adjusting component to rotate, thereby improving the operability of the adjusting mechanism.

[0011] Furthermore, the base is provided with a pair of limiting walls, which are located on the outer peripheral side of the friction pad, are gap-matched with the friction pad, and are relatively arranged along the length direction of the slider, and in the width direction of the slider, the friction pad is exposed between the pair of limiting walls. In this way, the position of the friction pad can be limited by the limiting walls, thereby improving the installation accuracy between the base and the friction pad.

[0012] Preferably, the friction pad has a plurality of claws, which are respectively located on both sides of the friction pad along the width direction of the slider, and the base is provided with a clamping portion that is engaged with the claws. In this way, the friction pad can be fixed to the base through the claws, further improving the installation accuracy between the base and the friction pad.

[0013] The present invention also provides a window, comprising a fixed outer frame that is fixedly arranged, and a window sash that can be opened and closed and assembled in the fixed outer frame, and also comprises the window wind brace as described above, wherein the guide rail of the window wind brace is arranged on the window sash or the fixed outer frame, and one end of the connecting rod of the window wind brace is rotatably connected to the fixed outer frame or the window sash.

[0014] As described above, the window wind brace and the window including the window wind brace according to the present invention have the following beneficial effects:

[0015] The force required for opening and closing the window sash can be adjusted to maintain the force required for opening and closing the window sash at an appropriate size. At the same time, the wear of the friction pad can be effectively reduced, the adjustment function of the adjustment mechanism can be ensured, and the service life and operability of the adjustment mechanism can be improved.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0053] like Figure 1 As shown, the window of the present invention comprises a fixed outer frame 10, a window sash 20 and a window wind brace 30. The fixed outer frame 10 is fixed at the window opening of the building, and generally comprises a pair of vertical outer frame profiles extending up and down and a pair of horizontal outer frame profiles extending left and right. The window sash 20 is assembled in the fixed outer frame 10 so as to be openable and closable, and generally comprises a sash frame, a door and window panel fixed in the sash frame, and a handle mounted on the sash frame, and the sash frame comprises a pair of vertical sash frame profiles extending up and down and a pair of horizontal sash frame profiles extending left and right.

[0054] like Figure 1 As shown, the window wind stay 30 is rotatably connected between the lower side transverse outer frame profile 11 of the fixed outer frame 10 and the lower side transverse sash frame profile 21 of the window sash 20 . Figure 2 For Figure 1 When the bottom of the window is viewed upward, the structural diagram of the window wind support 30 is as follows: Figure 2As shown, the window wind stay 30 mainly includes a guide rail 31, a slider 32 and a connecting rod 33. The guide rail 31 is arranged on the lower side transverse sash frame profile 21 of the window sash 20. The slider 32 is arranged in the slide groove 311 of the guide rail 31 and can slide along the length direction of the guide rail 31. One end of the connecting rod 33 is rotatably connected to the lower side transverse sash frame profile 11 of the fixed outer frame 10, and the other end of the connecting rod 33 is rotatably connected to the slider 32 through the cooperation of the rotating shaft and the first shaft hole 3224. When the window sash 20 is opened and closed, the window sash 20 drives the slider 32 to slide in the slide groove 311 of the guide rail 31, so that the window wind stay 30 can adapt to different window sash opening angles. Of course, in other embodiments, the guide rail 31 can also be arranged on the lower side transverse sash frame profile 11 of the fixed outer frame 10, one end of the connecting rod 33 is rotatably connected to the lower side transverse sash frame profile 21 of the window sash 20, and the other end of the connecting rod 33 is rotatably connected to the slider 32. In addition, the guide rail 31 may be integrally formed with the outer frame profile 11 or the window sash 20 , or may be fixed to the outer frame profile 11 or the window sash 20 via a fixing structure.

[0055] like Figure 3 , 4 As shown in Figures 5 and 6, the slider 32 is provided with an adjustment mechanism 321, which includes a base 322, a friction pad 324 and an adjustment component 325. The base 322 is provided on the slider 32, the friction pad 324 is located above the base 322 and between the two inner side walls 312 of the slide groove 311, the friction pad 324 is an elastically deformable annular component, the adjustment component 325 is provided in the friction pad 324 and is rotatably connected to the base 322, and the outer side surface of the adjustment component 325 is a smooth curved surface. After the window wind stay 30 is installed, the adjustment component 325 can press the friction pad 324 against the two inner side walls 312 of the slide groove 311 by rotating the adjustment component 325, thereby changing the pressure between the friction pad 324 and the two inner side walls 312 of the slide groove 311, and thus adjusting the friction between the slider and the guide rail when the slider slides in the guide rail.

[0056] Therefore, the friction between the slider 32 and the guide rail 31 can be adjusted by the adjustment mechanism 321, and the force required for opening and closing the window sash can be adjusted, so that the force required for opening and closing the window sash is maintained at an appropriate size, that is, the window sash can be maintained at a desired opening angle and avoid danger when the window sash is pushed by strong wind. At the same time, since the outer side surface of the adjustment component 325 is a smooth curved surface, the friction pad 324 can be prevented from being cut when the adjustment component 325 presses the friction pad 324 against the two inner side walls 312 of the slide groove 311, effectively reducing the wear of the friction pad 324, ensuring the adjustment function of the adjustment mechanism 321, and improving the service life of the adjustment mechanism 321.

[0057] Furthermore, if Figure 3 , 4As shown, the outer side surface of the adjusting component 325 is enclosed in an ellipse, and the sum of the long diameter of the ellipse and the thickness of the two side walls of the friction pad 324 arranged opposite to each other along the width direction of the slider 32 is greater than the distance between the two inner side walls 312 of the slide groove, that is, the sum of the long diameter of the ellipse and the thickness of a pair of straight portions 3241 of the friction pad 324 described later is greater than the distance between the two inner side walls 312 of the slide groove. In the initial position, the short diameter direction of the adjusting component 325 is consistent with the width direction of the slider 32. When adjusting the friction between the slider 32 and the guide rail 31, the adjusting component 325 is rotated so that the long diameter direction of the adjusting component 325 rotates toward the width direction of the slider 32. According to the required friction force, the rotating adjusting component 325 is rotated to a certain angle and then stopped at the angle. The greater the rotation angle, the greater the friction between the friction pad 324 and the two inner side walls 312 of the slide groove 311. Thus, the friction between the friction pad 324 and the two inner side walls 312 of the chute 311 can be gradually increased by rotating the angle of the adjusting component 325, and the adjusting component 325 can smoothly contact the friction pad 324, effectively reducing the wear of the friction pad 324. At the same time, since the sum of the long diameter of the ellipse and the thickness of the two side walls of the friction pad 324 arranged opposite to each other along the width direction of the slider 32 is greater than the distance between the two inner side walls 312 of the chute 311, it is possible to ensure that sufficient friction is generated between the friction pad 324 and the two inner side walls 312 of the chute 311, thereby avoiding the window sash from being unable to maintain the required opening angle due to the small friction, and avoiding danger when the window sash is pushed by strong wind. In addition, if the friction pad 324 is worn and thinned after long-term use, so that even if the adjusting component 325 is rotated, it is still impossible to ensure that sufficient friction is generated between the friction pad 324 and the two inner side walls 312 of the chute 311, a new friction pad 324 can be replaced to provide sufficient friction. In other embodiments, the major diameter of the elliptical outer side surface of the adjusting component 325 may be greater than the distance between the two inner side walls 312 of the chute. In this way, even if the friction pad 324 is worn and thinned after long-term use, the adjusting component 325 can be rotated to ensure that sufficient friction is generated between the friction pad 324 and the two inner side walls 312 of the chute 311. Furthermore, when the friction pad is damaged, the adjusting component 325 can be rotated to press the adjusting component 325 against the two inner side walls 312 of the chute 311, thereby generating sufficient friction between the adjusting component 325 and the two inner side walls 312 of the chute 311.

[0058] In addition, although the adjusting component 325 is rotatably connected to the base 322, a certain force is required to rotate the adjusting component 325. Therefore, after the adjusting component 325 is rotated to the desired angle, the adjusting component 325 can stop at this angle. When the slider 32 slides in the guide rail 31, the adjusting component 325 will not rotate due to the mutual compression between the friction pad 324 and the two inner walls 312 of the slide groove 311, ensuring that the friction force between the friction pad 324 and the two inner walls 312 of the slide groove 311 is maintained at the desired size.

[0059] like Figure 4 , 5 As shown, the bottom surface of the adjusting component 325 has a shaft portion 3252 extending downward, and the base 322 is provided with a second shaft hole 3225 that passes through the base 322 from top to bottom. After the shaft portion 3252 extends into the second shaft hole 3225, the adjusting component 325 is rotatably connected to the base 322 by riveting. After the adjusting component 325 is rotatably connected to the base 322, the adjusting component 325 can rotate in both clockwise and counterclockwise directions, and the rotation in both directions will not cause the adjusting component 325 to cut the friction pad 324. Therefore, it is convenient for the operator to rotate the adjusting component 325 in the rotation direction he is accustomed to, and adjust the friction between the friction pad 324 and the two inner side walls 312 of the slide groove 311, thereby improving the operability of the adjusting mechanism 321.

[0060] Furthermore, if Figure 4 , 5 As shown, the adjustment mechanism 321 may further include a disc spring 323, and the disc spring 323 is located between the base 322 and the adjustment component 325. In this way, the gap between the base 322 and the adjustment component 325 can be absorbed by the elastic deformation of the disc spring 323, so that the adjustment component 325 will not loosen, thereby improving the operability of the adjustment mechanism.

[0061] Furthermore, if Figure 3 , 4 As shown in FIG. 5 , an adjustment hole 3251 is provided on the upper surface of the adjustment component 325, and the shape of the adjustment hole 3251 is preferably a hexagon or a straight line. By providing the adjustment hole 3251, an operator can insert a tool such as a screwdriver that matches the shape of the adjustment hole 3251 into the adjustment hole 3251 to drive the adjustment component 325 to rotate. In this way, the operator can rotate the adjustment component 325 with a small force using the tool.

[0062] Furthermore, if Figure 4 , 5As shown, a pair of limiting walls 3221 are provided on the base 322, and the pair of limiting walls 3221 are located on the outer peripheral side of the friction pad 324, and are gap-matched with the friction pad 324, and are relatively arranged along the length direction of the slider 32, and in the width direction of the slider 32, the friction pad 324 is exposed between the pair of limiting walls 3221. In this way, the position of the friction pad 324 can be limited by the limiting walls 3221, the installation accuracy between the base 322 and the friction pad 324 is improved, and when the adjustment component 325 presses the friction pad 324 against the two inner side walls 312 of the slide groove 311, the friction pad 324 can be prevented from being misaligned.

[0063] like Figure 3 , 4 As shown, the friction pad 324 is an annular component surrounded by a pair of straight portions 3241 arranged opposite to each other along the width direction of the slider 32 and a pair of arc-shaped portions 3242 arranged opposite to each other along the length direction of the slider 32. The pair of straight portions 3241 respectively have an extending portion 3243 extending downward, and the outer side surface of the extending portion 3243 is opposite to the two inner side walls 312 of the slide groove 311. Each extension portion 3243 is provided with claws 3244 on both sides along the length direction of the slider 32, and the four claws 3244 are respectively located at the two ends of a pair of limiting walls 3221. A thin-walled portion 3222 and four engaging portions 3223 cooperating with the extending portion 3243 are provided on the base 322. The four claws 3244 can be respectively engaged with the four engaging portions 3223 through elastic deformation. In this way, the friction pad 324 can be fixed on the base 322 by the claws 3244, so as to further improve the installation accuracy between the base 322 and the friction pad 324, and avoid the misalignment of the friction pad 324. In other embodiments, the friction pad 324 can also be an annular component of other shapes, and there can be two claws, which are relatively arranged on both sides of the friction pad 324 along the width direction of the slider, and the base 322 is provided with two engaging parts respectively engaged with the two claws, and the two engaging parts are relatively arranged on both sides of the base 322 along the width direction of the slider.

[0064] Therefore, the present invention effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0065] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
