Description

Window wind brace and window

Technical Field

The utility model relates to the technical field of doors and windows, in particular to a window wind stay and a window comprising the window wind stay.

Background

The existing window mainly comprises a fixed outer frame which is fixedly arranged, a window sash which can be assembled in the fixed outer frame in an openable manner, and a window wind support. The window wind support mainly comprises a guide rail arranged on a fixed outer frame or a window sash, a sliding block arranged in a guide rail chute and capable of sliding along the length direction of the guide rail, and a connecting rod with one end rotationally connected with the window sash or the fixed outer frame and the other end rotationally connected with the sliding block. When the window sashes are opened and closed, the window sashes drive the sliding blocks to slide in the guide rail sliding grooves, so that the wind brace is suitable for different window sashes opening angles.

If the force required for opening and closing the window sash is small, the window sash can move under the condition that the window sash is opened by small force, so that the window sash is difficult to maintain at a required opening angle, and on the other hand, when strong wind is encountered, the strong wind can push the window sash to impact the fixed window frame with great force, so that danger is caused. Therefore, the sliding blocks of some window windshields are provided with adjusting mechanisms, and the friction force between the sliding blocks and the guide rails can be adjusted through the adjusting mechanisms, so that the force required for opening and closing the window sashes is adjusted, and the force required for opening and closing the window sashes is maintained at a proper size. The specific structure of the adjusting mechanism is as follows: the sliding block sliding guide rail comprises a base, a friction pad arranged on the base and an adjusting component arranged in the friction pad and rotationally connected with the base, wherein the friction pad can elastically deform and is positioned between two inner side walls of the sliding groove, and the pressure between the friction pad and the inner side walls of the sliding groove can be changed by rotating the adjusting component, so that the friction force between the sliding block and the sliding rail when the sliding block slides in the sliding rail can be changed. In the above-described adjusting mechanism, since the outer profile of the adjusting member has a sharp ridge, the adjusting member cuts the friction pad when contacting the friction pad, resulting in abrasion of the friction pad and a decrease in the adjusting function.

Further, the outer side surface of the adjusting part is enclosed into an ellipse, and the sum of the thicknesses of two side walls of the ellipse, which are arranged opposite to the friction pad along the width direction of the sliding block, is larger than the distance between the two inner side walls of the sliding groove. Because the outer side surface of the adjusting part surrounds an ellipse, the adjusting part can smoothly contact with the friction pad when the adjusting part is rotated, and the abrasion of the friction pad is effectively reduced. Meanwhile, the sum of the thickness of the two side walls of the oval long diameter and the friction pad which are oppositely arranged along the width direction of the sliding block is larger than the distance between the two inner side walls of the sliding groove, so that enough friction force can be generated between the friction pad and the two inner side walls of the sliding groove.

Further, the adjustment member is rotatable in both a clockwise and a counter-clockwise direction. Thereby, the operability of the adjustment mechanism can be improved.

Further, the adjustment mechanism also includes a belleville spring positioned between the base and the adjustment member.

Therefore, the position of the friction pad can be limited by the limiting wall, and the installation accuracy between the base and the friction pad is improved.

Preferably, the friction pad has a plurality of claws, the plurality of claws are respectively located at two sides of the friction pad along the width direction of the sliding block, and the base is provided with a clamping part which is clamped with the claws.

As shown in fig. 1, the window according to the present utility model includes a fixed frame 10, a window sash 20, and a window stay 30. The fixed frame 10 is fixed to the window opening of a building and generally includes a pair of vertical frame profiles extending up and down and a pair of lateral frame profiles extending left and right. The window sash 20 is openably and closably assembled in the fixed housing 10, and generally includes a sash frame including a pair of vertical sash frame profiles extending up and down and a pair of lateral sash frame profiles extending left and right, a door and window panel fixed in the sash frame, and a handle mounted on the sash frame.

As shown in fig. 1, the window stay 30 is rotatably connected between the lower lateral frame profile 11 of the fixed frame 10 and the lower lateral frame profile 21 of the window sash 20. Fig. 2 is a schematic structural view of the window stay 30 when viewed from the bottom of fig. 1, as shown in fig. 2, the window stay 30 mainly includes a guide rail 31, a slider 32 and a connecting rod 33, the guide rail 31 is disposed on the lower lateral sash profile 21 of the window sash 20, the slider 32 is disposed in a sliding slot 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 rotationally connected with the lower lateral frame profile 11 of the fixed frame 10, and the other end of the connecting rod 33 is rotationally connected with the slider 32 through the cooperation of a rotating shaft and a first shaft hole 3224. When the window sash 20 is opened and closed, the window sash 20 drives the sliding block 32 to slide in the sliding groove 311 of the guide rail 31, so that the window sash support 30 is adapted to different window sash opening angles. Of course, in other embodiments, the guide rail 31 may be provided on the lower lateral frame profile 11 of the fixed frame 10, one end of the link 33 is rotatably connected to the lower lateral frame profile 21 of the window sash 20, and the other end of the link 33 is rotatably connected to the slider 32. 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 by a fixing structure.

As shown in fig. 3, 4 and 5, the slider 32 is provided with an adjusting mechanism 321, and the adjusting mechanism 321 includes a base 322, a friction pad 324 and an adjusting member 325. The base 322 is disposed on the slider 32, the friction pad 324 is disposed above the base 322 and between the two inner sidewalls 312 of the chute 311, the friction pad 324 is an elastically deformable annular member, the adjusting member 325 is disposed in the friction pad 324 and is rotatably connected with the base 322, and an outer side surface of the adjusting member 325 is a smooth curved surface. After the window stay 30 is installed, the adjusting part 325 can press the friction pad 324 against the two inner side walls 312 of the sliding groove 311 by rotating the adjusting part 325, so that the pressure between the friction pad 324 and the two inner side walls 312 of the sliding groove 311 can be changed, and the friction force between the sliding block and the guide rail when the sliding block slides in the guide rail can be adjusted.

Therefore, the friction force between the slider 32 and the guide rail 31 can be adjusted by the adjusting mechanism 321, so that the force required for opening and closing the window sash can be adjusted, the force required for opening and closing the window sash can be maintained at a proper magnitude, that is, the window sash can be maintained at a required opening angle, and the danger caused when the window sash is pushed by strong wind can be avoided. Meanwhile, since the outer side surface of the adjusting part 325 is a smooth curved surface, the friction pad 324 can be prevented from being cut when the friction pad 324 is pressed against the two inner side walls 312 of the sliding groove 311 by the adjusting part 325, the abrasion of the friction pad 324 is effectively reduced, the adjusting function of the adjusting mechanism 321 is ensured, and the service life of the adjusting mechanism 321 is prolonged.

Further, as shown in fig. 3 and 4, the outer side surface of the regulating member 325 is formed in an elliptical shape, and the sum of the long diameter of the elliptical shape and the thickness of the two side walls of the friction pad 324 disposed opposite to each other in the width direction of the slider 32 is larger than the distance between the two inner side walls 312 of the slide groove, that is, the sum of the long diameter of the elliptical shape and the thickness of a pair of flat portions 3241 of the friction pad 324 described later is larger than the distance between the two inner side walls 312 of the slide groove. In the initial position, the short diameter direction of the regulating member 325 coincides with the width direction of the slider 32, and when the frictional force between the slider 32 and the guide rail 31 is regulated, the regulating member 325 is rotated so that the long diameter direction of the regulating member 325 is rotated in the width direction of the slider 32, and the rotation regulating member 325 is rotated by a predetermined angle according to the required frictional force and then stopped at the angle, and the frictional force between the friction pad 324 and the two inner side walls 312 of the slide groove 311 increases as the rotation angle increases. Thereby, the friction force between the friction pad 324 and the two inner side walls 312 of the sliding groove 311 can be gradually increased by rotating the angle of the adjusting member 325, and the adjusting member 325 can smoothly contact with the friction pad 324, effectively reducing the abrasion of the friction pad 324. Meanwhile, since the sum of the thickness of the two opposite side walls of the oval long diameter and the friction pad 324 along the width direction of the slider 32 is greater than the distance between the two inner side walls 312 of the sliding slot 311, it is possible to ensure that a sufficient friction force is generated between the friction pad 324 and the two inner side walls 312 of the sliding slot 311, to avoid that the window sash cannot be maintained at a desired opening angle due to a small friction force, and to avoid danger when strong wind pushes the window sash. In addition, if the friction pad 324 becomes worn and thinned after a long period of use, so that a sufficient friction force cannot be ensured between the friction pad 324 and the two inner side walls 312 of the chute 311 even if the regulating member 325 is rotated, a sufficient friction force can be provided by replacing the new friction pad 324. In other embodiments, the length of the oval outer side of the adjustment member 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 wears down after a long period of use, it is possible to ensure that a sufficient friction force is generated between the friction pad 324 and the two inner side walls 312 of the chute 311 by rotating the regulating member 325, and further, when the friction pad is damaged, it is possible to press the regulating member 325 against the two inner side walls 312 of the chute 311 by rotating the regulating member 325, thereby generating a sufficient friction force between the regulating member 325 and the two inner side walls 312 of the chute 311.

In addition, although the regulating member 325 is rotatably connected to the base 322, since a certain force is required to rotate the regulating member 325, the regulating member 325 can be stopped at a desired angle after the regulating member 325 is rotated to the angle, and when the slider 32 slides in the guide rail 31, the regulating member 325 does not rotate due to the pressing of the friction pad 324 against the two inner side walls 312 of the slide groove 311, thereby ensuring that the friction force between the friction pad 324 and the two inner side walls 312 of the slide groove 311 is maintained at a desired level.

As shown in fig. 4 and 5, the bottom surface of the adjusting member 325 has a shaft portion 3252 extending downward, the base 322 is provided with a second shaft hole 3225 penetrating the base 322 up and down, and the shaft portion 3252 extends into the second shaft hole 3225 and is then pivotally connected to the base 322 by caulking. After the adjustment member 325 is rotatably coupled to the base 322, the adjustment member 325 may be rotated in both a clockwise direction and a counterclockwise direction, both of which may not cause the adjustment member 325 to cut the friction pad 324. Thus, the operator can conveniently rotate the adjusting member 325 according to the rotation direction to which he is accustomed to, and adjust the friction between the friction pad 324 and the two inner side walls 312 of the chute 311, thereby improving the operability of the adjusting mechanism 321.

Further, as shown in fig. 4 and 5, the adjusting mechanism 321 may further include a belleville spring 323, where the belleville spring 323 is located between the base 322 and the adjusting member 325. In this way, the clearance between the base 322 and the regulating member 325 can be absorbed by the elastic deformation of the disc spring 323, so that the regulating member 325 is not loosened, and the operability of the regulating mechanism is improved.

Further, as shown in fig. 3, 4 and 5, the upper surface of the adjusting member 325 is provided with an adjusting hole 3251, and the adjusting hole 3251 is preferably hexagonal or linear. By providing the adjustment hole 3251, an operator can insert a tool such as a screwdriver, which matches the shape of the adjustment hole 3251, into the adjustment hole 3251 to rotate the adjustment member 325. In this manner, the operator can rotate the adjustment member 325 with less force using the tool.

Further, as shown in fig. 4 and 5, the base 322 is provided with a pair of stopper walls 3221, the pair of stopper walls 3221 are located on the outer peripheral side of the friction pad 324, are in clearance fit with the friction pad 324, are disposed opposite to each other along the length direction of the slider 32, and the friction pad 324 is exposed from between the pair of stopper walls 3221 in the width direction of the slider 32. In this way, the position of the friction pad 324 can be restricted by the restricting wall 3221, the mounting accuracy between the base 322 and the friction pad 324 can be improved, and when the adjusting member 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 dislocated.

As shown in fig. 3 and 4, the friction pad 324 is an annular member surrounded by a pair of straight portions 3241 disposed opposite to each other in the width direction of the slider 32 and a pair of arc portions 3242 disposed opposite to each other in the length direction of the slider 32, the pair of straight portions 3241 each have a downward extending portion 3243, the outer side surfaces of the extending portions 3243 are opposite to the two inner side walls 312 of the slide groove 311, each extending portion 3243 is provided with a claw 3244 on both sides in the length direction of the slider 32, the four claws 3244 are respectively located at both ends of the pair of stopper walls 3221, the base 322 is provided with a thin wall portion 3222 and four engaging portions 3223 engaged with the extending portions 3243, and the four claws 3244 are respectively engageable with the four engaging portions 3223 by elastic deformation. In this way, the friction pad 324 can be fixed on the base 322 by the claw 3244, so that the installation accuracy between the base 322 and the friction pad 324 is further improved, and the dislocation of the friction pad 324 is avoided. In other embodiments, the friction pad 324 may be an annular member with other shapes, and the two claws may be disposed on two sides of the friction pad 324 opposite to each other along the width direction of the slider, and the base 322 is provided with two engaging portions engaged with the two claws, and the two engaging portions are disposed on two sides of the base 322 opposite to each other along the width direction of the slider.
