Description

Technical Field

[0001] The utility model relates to the technical field of production of casement-hung windows, in particular to a casement-hung window sliding support assembly with a shaking prevention function and an outward-opening top-hung window. Background Art

[0002] Casement-hung windows are a general term for windows that can be opened and closed both horizontally (i.e., casement-hung) and vertically (i.e., suspended). Based on their functional characteristics, they can be categorized into four basic types: outward-opening top-hung, outward-opening bottom-hung, inward-opening top-hung, and inward-opening bottom-hung. However, based on practical application needs, outward-opening top-hung and inward-opening bottom-hung windows are the two most popular types of casement-hung windows on the market. Outward-opening top-hung windows offer two opening methods: one side pivoting outward and the lower portion pivoting outward. Inward-opening bottom-hung windows offer two opening methods: one side pivoting inward and the upper portion pivoting inward. They are often referred to as inward-opening tilt-and-tilt windows.

[0003] The lower end of the window frame and the lower end of the window sash of the casement hung window or the upper end of the window frame and the upper end of the window sash are connected by a sliding support assembly. The basic structure of the sliding support assembly includes a window frame horizontal connecting rod for connecting to the window frame, a window sash horizontal connecting rod for connecting to the window sash, and a rotating assembly composed of multiple rotating rods. The window frame horizontal connecting rod and the window sash horizontal connecting rod are respectively connected to the rotating assembly. At least one sliding slider is installed on the window frame horizontal connecting rod, and the slider is rotationally connected to the rotating assembly. During the casement and hanging process of the window sash of the casement hung window, the slider will slide on the window frame horizontal connecting rod.

[0004] In the sliding support assembly of traditional casement hung windows, the slider is usually installed in the slide groove on the horizontal connecting rod of the window frame. The sliding structure of the slider and the slide groove has the following defects: on the one hand, rain, dust or other foreign matter can easily enter the slide groove, resulting in obstruction of the slider movement, uneven operation, and even jamming and difficulty in opening and closing the window sash, affecting the normal opening and closing function of the window sash; on the other hand, it is difficult to achieve the wind and swing prevention function after the window sash is opened by cooperating with the slider and the slide groove. At present, various adjustable wind and swing prevention fasteners are generally used between the slider and the slide groove, or several blocking bumps are raised at the bottom of the slide groove, and the slider slowly passes through the blocking bumps, or a rubber slide groove seat is used to increase the friction coefficient to achieve the wind and swing prevention effect. These structures have the problems of either being able to prevent wind and swing but the opening and closing operation is laborious and not smooth, or being easy to open and close but the wind and swing prevention effect is poor, resulting in poor user experience and poor durability.

[0005] The conventional sliding support assembly of casement hung windows also adopts a structure in which a slider and a slide rail are matched, that is, a protruding convex edge is respectively provided on the upper part of both sides of the window frame horizontal connecting rod to form a slide rail, and a slide groove is respectively provided on the middle and lower parts of both sides of the slider, and the slide rails on both sides of the window frame horizontal connecting rod are respectively placed in the slide grooves on both sides of the slider. This structure can solve the above-mentioned problem of the slider movement being blocked and the operation being not smooth due to rain, dust or other foreign matter. However, this conventional sliding support assembly is mainly used for casement hung windows. If it is used for casement hung windows, a larger gap is required between the groove wall of the slider groove and the slide rail to avoid the problem of bending of the rotating assembly when hanging, so that the instability between the slider and the window frame horizontal connecting rod is increased, resulting in the problem of shaking of the window sash during use; in addition, the above-mentioned conventional sliding support assembly does not have a reasonable windproof and anti-swing structure, that is, the window sash cannot be positioned after opening, and will swing or close when the wind blows. If it is used for casement hung windows, the larger gap between the groove wall of the slider groove and the slide rail further increases the difficulty of setting a windproof and anti-swing structure between the slider and the slide rail. Utility Model Content

[0006] The purpose of the present invention is to provide a sliding support assembly for a casement-hung window and an outward-opening top-hung window with a shaking prevention function in order to solve the above-mentioned problem.

If multiple positioning points corresponding to multiple opening angles are set for each opening state, more elastic positioning members need to be installed.

[0012] Preferably, in order to facilitate the quick and stable installation of the elastic positioning member, 1-3 snap holes are provided on the groove wall of the mounting groove, and a snap that protrudes outward and corresponds to the snap hole one by one is provided on one side of the elastic positioning member. The snap is placed in the corresponding snap hole. In order to meet the application requirements of different vertical displacement amounts of both sides of the slider relative to the slide rail in the hanging state, the chute is a "C" - shaped groove and the vertical heights of the chutes on both sides of the same slider are different.

[0013] Preferably, in order to facilitate a more reliable connection between the slider and the window frame cross-link and to avoid the elastic positioning member affecting the sliding of the slider, a rail groove is provided under the slide rails on both sides of the window frame cross-link, and the lower parts of both sides of the slider are placed in the corresponding rail grooves. The upper part of the elastic positioning member is provided with a rail corresponding to and connected to the slide rail, and the arc-shaped protrusion is provided in the middle of the rail and protrudes in the laterally outward direction. The lower middle part of the elastic positioning member is provided with a groove and the groove corresponds to and is connected to the rail groove.

[0014] Preferably, in order to make the raised portion of the elastic positioning member elastic so as to improve the windproof and anti-swaying effect after positioning and increase its service life, the elastic positioning member is an elastic plastic member, and the plastic in the raised portion and the plastic in the rail are an integrally molded grid-shaped plastic.

[0015] Preferably, to achieve a better fit between the slider and the window frame cross-link and facilitate installation of the stop tube, a downwardly sunken strip groove is provided in the middle portion of the upper portion of the window frame cross-link. The length of the strip groove is the same as that of the window frame cross-link. A downwardly protruding boss is provided below the middle portion of the slider. The bottom of the boss is positioned within the strip groove. The stop tube passes through the boss, and the ball bearing is in close contact with the bottom of the strip groove. Because the strip groove does not require a nearly tight fit with the slider boss, a relatively large gap can be provided. Therefore, the drawback of rainwater, dust, or other foreign matter accumulating in conventional sliding grooves provided on the window frame cross-link is avoided.

[0016] Preferably, in order to better connect with the window sash and realize the corner transmission function of the window sash away from the handle side, the sliding support assembly of the casement hung window with anti-swaying function also includes a transverse transmission rod, an elastic transmission belt, a vertical transmission rod and a window sash vertical connecting rod for connecting with the window sash, the transverse transmission rod is located above the window sash transverse connecting rod, one end of the transverse transmission rod is connected to one end of the elastic transmission belt that is bent 90° in an arc, the other end of the elastic transmission belt is connected to the lower end of the vertical transmission rod, and the window sash vertical connecting rod is located on the side of the vertical transmission rod away from the window sash transverse connecting rod.

[0018] The beneficial effects of the present invention are:

[0019] The utility model provides a track-type sliding structure by arranging slide rails on both sides of the window frame cross-link and placing them in the slide grooves on both sides of the slider respectively. Compared with the matching structure of the traditional slider being placed in the slide groove, rainwater, dust or other foreign matter will not be deposited, so there will be no problem of jamming that affects the opening and closing of the window sash, and the opening and closing operation is smoother. By installing a limit tube with a built-in compression spring and ball on the slider, the ball can maintain an elastic and close contact state with the window frame cross-link at any time, and the small contact area and rolling function of the ball will not affect the normal sliding of the slider, thereby compensating for the gap between the groove wall of the slider slide groove and the slide rail. The window sash shaking defect caused by the existence of a large gap is eliminated, so that the window sash remains in a stable state during use; by installing an elastic positioning piece on at least one slide rail, an elastic protrusion is provided on the elastic positioning piece, and when the slider slides to the position of the elastic positioning piece, the protrusion is in close contact with the groove wall of the corresponding slide groove. When the window sash is opened to a certain angle, it is in a positioned state due to the large friction force. In this state, the window sash is not easily blown by the wind, thereby realizing the wind-proof swinging function. Moreover, the structure is integrated on the slider and the window frame cross-link, and there is no need to install related components separately, which is conducive to realizing more other functions in other positions.

[0031] The present invention will be further described below with reference to the accompanying drawings:

[0032] like Figures 1-8 As shown, the sliding support assembly of the casement window with the anti-swaying function of the present invention includes a sliding support assembly for connecting with the window frame (reference Figures 9-11 30) connected to the window frame cross rod 15, for the window sash (reference Figures 9-11 The window sash 31) is connected to the window sash horizontal connecting rod 5 and a rotating assembly composed of multiple rotating rods (refer to the first rotating rod 6, the second rotating rod 7, the third rotating rod 9 and the fourth rotating rod 8 in the following content), the window frame horizontal connecting rod 15 and the window sash horizontal connecting rod 5 are respectively connected to the rotating assembly, and at least one sliding slider is installed on the window frame horizontal connecting rod 15 (refer to the first slider 11 and the second slider 12 in the following content, the first slider 11 and the second slider 12 have the same structure, the same width and different lengths, and the related structure of the slider below is the related structure of the first slider 11 and the second slider 12) and the slider rotates with the rotating assembly Rotation connection, the upper parts of both sides of the window frame horizontal connecting rod 15 are respectively provided with outwardly protruding convex edges and form sliding rails 17, and the middle and lower parts of both sides of the slider (the first slider 11 or the second slider 12, the same below) are respectively provided with sliding grooves 20, and the sliding rails 17 on both sides of the window frame horizontal connecting rod 15 are respectively placed in the sliding grooves 20 on both sides of the slider, and there is a gap between the sliding rails 17 and the groove walls of the corresponding sliding grooves 20. The slider is provided with a vertical through hole and a limiting tube 10 with an open lower end and a closed upper end is installed in the through hole. The limiting tube 10 is provided with a compression spring (not visible in the figure) and a ball 23 arranged from top to bottom, and the ball 23 is in close contact with the top of the window frame horizontal connecting rod 15.

[0033] like Figures 1-8 As shown, the present invention also discloses the following multiple more optimized specific structures:

[0034] In order to better realize the casement and suspended functions of the window sash, the slider includes a first slider 11 and a second slider 12 which are arranged in the length direction of the window frame horizontal connecting rod 15 and have the same structure, the same width, and different lengths (which can also be the same). The rotating assembly includes a first rotating rod 6, a second rotating rod 7, a third rotating rod 9 and a fourth rotating rod 8. The position near the first end of the first rotating rod 6 is rotatably connected to the window sash horizontal connecting rod 5 and is located below the window sash horizontal connecting rod 5. The second end of the first rotating rod 6 is rotatably connected to the first end of the second rotating rod 7, the second end of the second rotating rod 7 is rotatably connected to the first end of the first slider 11, the second end of the first slider 11 is rotatably connected to the first end of the third rotating rod 9, the second end of the third rotating rod 9 is rotatably connected to the middle section of the fourth rotating rod 8, the first end of the fourth rotating rod 8 is rotatably connected to the second slider 12, and the second end of the fourth rotating rod 8 is rotatably connected to the middle section of the first rotating rod 6. In actual application, the first slider 11 can be moved and the second slider 12 can be fixed, or the second slider 12 can be moved and the first slider 11 can be fixed, and the normal opening function of the window sash can be achieved. It is just necessary to determine the fixed slider of the first slider 11 and the second slider 12 at a position close to one end of the window frame horizontal connecting rod 15; the length of the first slider 11 of this embodiment is greater than the length of the second slider 12. The first slider 11 serves as a fixed slider and does not slide during use. The second slider 12 serves as a movable slider and follows the sliding during use.

[0035] In order to realize the windproof and anti-swaying function of the window sash after opening, an elastic positioning member 13 is installed on at least one sliding rail 17, and an elastic protrusion 26 is provided on the elastic positioning member 13 and meets the following conditions: when the slider slides to the position of the elastic positioning member 13, the protrusion 26 is in close contact with the groove wall of the corresponding sliding groove 20.

[0036] To facilitate installation of the elastic locating members 13 and prevent them from interfering with the sliding movement of the slider, a mounting groove 14 is provided on at least one sidewall of the window frame cross-link 15. This mounting groove 14 vertically extends through the corresponding slide rail 17. There are at least two mounting grooves 14, which are arranged in sequence along the length of the window frame cross-link 15. Multiple elastic locating members 13 are respectively placed in these mounting grooves 14. The specific number of elastic locating members 13 is determined according to actual needs. At least two elastic locating members 13 correspond to the two opening states of the window sash: casement opening and cantilever opening. If multiple positioning points corresponding to opening angles are provided for each opening state, more elastic locating members 13 will need to be installed.

[0037] To facilitate the quick and stable installation of the elastic positioning member 13, there are 1 - 3 snap holes 24 (2 in the figure) provided on the groove wall of the installation groove 14. On one side of the elastic positioning member 13, there are outwardly protruding snaps 25 that correspond to the snap holes 24 one by one, and the snaps 25 are placed in the corresponding snap holes 24. To meet the application requirements of different vertical displacement amounts on both sides of the slider relative to the slide rail 17 in the suspended - open state, the chute 20 is a "C" - shaped groove and the vertical heights of the chutes 20 on both sides of the same slider are different.

[0038] To facilitate a more reliable connection between the slider and the window - frame horizontal connecting rod 15 and prevent the elastic positioning member 13 from affecting the sliding of the slider, there are rail grooves 18 provided below the slide rails 17 on both sides of the window - frame horizontal connecting rod 15. The lower parts on both sides of the slider are placed in the corresponding rail grooves 18. The upper part of the elastic positioning member 13 has rail strips 27 that correspond to and are connected to the slide rails 17. An arc - shaped convex part 26 is provided in the middle of the rail strip 27 and protrudes in the lateral - outer direction. The middle - lower part of the elastic positioning member 13 has a groove 28 that corresponds to and is connected to the rail groove 18.

[0039] To make the convex part 26 of the elastic positioning member 13 elastic to improve the wind - proof and anti - sway effect after positioning and increase its service life, the elastic positioning member 13 is an elastic plastic part with good toughness, and the plastic in the convex part 26 and the plastic in the rail strip 27 are integrally formed grid - like plastic 29.

[0040] To make the slider and the window - frame horizontal connecting rod 15 have a better matching effect and facilitate the installation of the limit tube 10, there is a sunken strip - shaped sink 16 in the middle of the upper surface of the window - frame horizontal connecting rod 15. The length direction of the strip - shaped sink 16 is the same as the length direction of the window - frame horizontal connecting rod 15. A downward - protruding boss 21 is provided on the lower surface of the middle part of the slider, and the lower surface of the boss 21 is placed in the strip - shaped sink 16. The limit tube 10 passes through the boss 21, and the ball 23 is in close contact with the bottom of the strip - shaped sink 16. Since the above - mentioned strip - shaped groove 16 does not require a close fit in a near - sealed state with the boss 21 of the slider and can have a relatively large gap, it does not have the defect of rainwater, dust or other foreign - matter accumulation existing in the chute provided on the window - frame horizontal connecting rod in the traditional structure. <​​​​​As shown, an outward-opening top-hung window includes a window frame 30, a window sash 31 and a lower sliding support assembly, wherein the lower sliding support assembly is the sliding support assembly of the casement-opening top-hung window with the anti-swaying function, the window sash vertical connecting rod 1 is connected to the vertical side of the window sash 31, the window sash horizontal connecting rod 5 is connected to the lower side of the window sash 31, and the window frame horizontal connecting rod 15 is connected to the lower side of the window frame 30.

[0043] Figure 1 、 Figure 4 、 Figure 6-Figure 8 Also shown is a connecting hole 19 provided on the window frame cross link 15, which is used to connect the window frame cross link 15 with the window frame 30. Figure 2 and Figure 3 Also shown are through holes 22 provided on the first slider 11 and the second slider 12 and used to connect with corresponding rotating rods, both of which are conventional structures.

[0044] like Figures 1-11 When the sash 31 is opened outward, the second slider 12 moves toward the first slider 11, and the ball 23 is in close contact with the window frame cross-link 15 under the elastic force of the compression spring, so that the sash 31 remains stable and does not shake during the opening process. When the second slider 12 slides to the position of the corresponding elastic positioning member 13, the protrusion 26 is in close contact with the groove wall of the corresponding sliding groove 20, generating a large friction force. At this time, the user can clearly feel that a large force is required to continue to push the sash 31 to rotate. At this time, the rotation of the sash 31 is stopped, and the sash 31 is in a positioned state. Figure 9 and Figure 10 As shown, even if the wind is not very strong, the window sash 31 cannot be blown to rotate and swing, thus realizing the windproof and anti-swing function. Generally, an elastic positioning member 13 can be set at the corresponding position of the window sash 31 at the maximum outward opening angle and the hanging opening angle, so that the positioning windproof and anti-swing function can be realized after the window sash 31 is opened in place. The positioning function can also be set when the window sash 31 is in a half-open state as needed, and it is only necessary to install the elastic positioning member 13 at the corresponding position. The window sash 31 remains stable and does not shake during the hanging process, and the corresponding positioning function is similar to the above. Although the gap between the boss 21 of the first slider 11 and the boss 21 of the second slider 12 and the bottom of the strip groove 16 of the window frame horizontal connecting rod 15 will increase, under the action of the compression spring, the ball 23 is still in close contact with the bottom of the strip groove 16 of the window frame horizontal connecting rod 15, and the window sash 31 can still remain stable and does not shake during the opening process. Figure 11 As shown, other specific processes will not be repeated.

[0045] In the actual application of the present invention, more structures and functions can be integrated on this basis. Specifically, refer to the structure disclosed in the utility model patent application document with patent application number "202410098166.5" and name "Multifunctional lower sliding support and steering angle control component for outward-opening top-hung windows". After replacing the associated components in the "Multifunctional lower sliding support and steering angle control component for outward-opening top-hung windows" with the rotating component, the first slider 11, the second slider 12 and the related connection structure with the window frame horizontal connecting rod 15 of the present invention, they are integrated together on the outward-opening top-hung window to achieve more positioning, transmission and control functions.

[0046] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
