Description

Technical Field

[0001] The present application relates to the technology of door and window hardware accessories, and more specifically, to a sliding support and a sliding rail and slider assembly thereof. Background Art

[0002] A sliding stay is a connecting rod type movable link device used to connect the window sash and the window frame so that the window can be opened and closed. The sliding stay generally includes a slide rail, a slider and a connecting rod mechanism, wherein the slide rail is fixed to the window frame by fasteners, the slider slides in a slide groove provided on the slide rail, and the connecting rod mechanism is hinged to the slider and the slide rail and connected to the window sash to realize the opening and closing of the window sash relative to the window frame.

[0003] There needs to be enough friction or resistance between the slider and the rail to ensure that the slider slides stably in the rail's groove and prevent the window sash from closing back and forth under the force of different wind directions. Conventional sliding supports on the market have a structure in the middle of the slider to adjust the friction between the slider and the rail, so that the rail cannot be fixed with screws within the sliding range of the slider, resulting in the rail being easily installed loosely and deformed during the sliding process of the slider. As the weight of the window sash increases, the deformation increases, affecting the high load-bearing performance design of the casement sliding support. Utility Model Content

[0035] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, the embodiments in the present application and the features in the embodiments may be combined with each other in the absence of conflict.

[0036] Figure 1 FIG. 1 is a schematic diagram showing a structure of a sliding support 100 according to an embodiment of the present application. Figure 1 As shown, the slide support 100 includes a slide rail and slider assembly 10 and a connecting rod assembly 20. The slide rail and slider assembly 10 is mainly composed of a slide rail 11, a slider 13, a pad 14 and an adjusting screw 15. The connecting rod assembly 20 is mainly composed of a first connecting rod 21, a second connecting rod 22, a third connecting rod 23 and a fourth connecting rod 24. The slide rail 11 has a first end 11a and a second end 11b opposite to each other, and is provided with a slide groove 12 passing through the first end 11a and the second end 11b. The bottom surface of the slide groove 12 is provided with a plurality of mounting holes 114 along its length direction for fasteners such as Figure 3 The fastening screws 16 shown are used to fix the slide rail 11 to the window frame profile. The slider 13 is slidably disposed in the slide groove 12 and can slide along the slide groove 12. The pad 14 is disposed on the upper portion of the slider 13. One end of the first connecting rod 21 is hinged with the slider 13 and the pad 14, and the other end of the first connecting rod 21 is hinged with the middle portion of the third connecting rod 23; one end of the second connecting rod 22 is hinged with the slider 13 and the pad 14, and the other end of the second connecting rod 22 is hinged with one end of the fourth connecting rod 24; one end of the third connecting rod 23 is hinged at the first end 11a of the slide rail 11, and the other end of the third connecting rod 23 is hinged with the other end of the fourth connecting rod 24; the fourth connecting rod 24 is used to connect the window sash profile to achieve the connection between the entire sliding support 100 and the window sash. When the slider 13 and the pad 14 are driven to slide toward the first end 11a of the slide rail 11 by the link mechanism 20, the window sash gradually opens relative to the window frame; when the slider 13 and the pad 14 are driven to slide toward the second end 11b of the slide rail 11 by the link mechanism 20, the window sash gradually closes relative to the window frame. The second end 11b of the slide rail 11 is provided with a wrap angle 17. When the links of the link mechanism 20 rotate to overlap with the slide rail 11, one end of the fourth link 24 is inserted into the wrap angle 17, and the window sash is in a completely closed state relative to the window frame.

[0037] See also Figure 2 and Figure 3As shown, the slide rail 11 can be formed by bending a plate, and has a bottom plate 111, two side plates 112 extending upward from opposite sides of the bottom plate 111, and two top plates 113 extending inward from the upper ends of the two side plates 112, thereby forming a slide groove 12 with an open mouth 121 at the upper end. The bottom surface of the slide groove 12, i.e., the bottom plate 111, is provided with a plurality of mounting holes 114 along its length direction, and corresponding fastening screws 16 pass through the mounting holes 114 to mount and fix the slide rail 11 to the window frame profile. The slider 13 is formed into an I-shaped body 131, a connecting block 132 connected to the middle of the top surface of the slider body 131, and two laps 133 extending outward from both sides of the top of the connecting block 132. The slider body 131 has a shape that matches the slide groove 12 and is slidably arranged in the slide groove 12. The connecting block 132 is placed in the open opening 121 at the upper end of the slide groove 12, and the laps 133 on both sides are respectively in contact with the top surfaces of the two top plates 113 of the slide rail 11. In this way, the slider 13 can slide along the slide groove 12 relative to the slide rail 11 and will not fall out of the slide groove 12.

[0038] See also Figure 2 and Figure 3 As shown, the slide rail slider assembly 10 is also provided with a backing plate 14 and an adjusting screw 15. The backing plate 14 is placed on the top of the slider 13, and a second rivet hole 141 is opened corresponding to the first rivet hole 134 on the slider 13. One end of the rod, such as the first connecting rod 21 and the second connecting rod 22, is respectively inserted through the corresponding second rivet hole 141 and the first rivet hole 134 through the rivet 25 to be riveted together with the backing plate 14 and the slider 13, and the backing plate 14 can slide along the slide rail 12 with the slider 13 through the rivet 25. Further, the backing plate 14 is formed with a boss 142 on the top of one side opposite to a lap 133 of the slider 13, and an internal threaded hole 143 is opened in the boss 142 to pass through the bottom surface of the backing plate 14, and the adjusting screw 15 is locked into the internal threaded hole 143 through a threaded connection to abut against the lap 133 of the slider 13. When the adjusting screw 15 is tightened downward, since the pad 14 is placed between the slider 13 and the rod, such as the first connecting rod 21 and the second connecting rod 22, and is riveted to the rod, the pad 14 cannot move upward, and the adjusting screw 15 will press the lap 133 of the slider 13 downward, causing the friction between the lap 133 and the top plate 113 of the slide rail 11 to increase, thereby increasing the friction between the slider 13 and the slide rail 11, and vice versa. The friction between the slider 13 and the slide rail 11 is reduced.

[0039] See also Figure 3As shown, the slider 13 is also provided with an upwardly concave avoidance groove 135 on the bottom surface of the slider body 131, and the avoidance groove 135 allows the screw head 161 of the fastening screw 16 to pass through, so that the slider 13 will not interfere with the fastening screw 16 when sliding in the slide groove 12 of the slide rail 11. In this way, more mounting holes 114 can be provided on the bottom plate 111 of the slide rail 11 within the sliding travel range of the slider 13, and the slide rail 11 and the window frame profile can be fixed by more fastening screws 16, so as to avoid deformation of the slide rail 11, improve the connection strength between the slide rail 11 and the window frame profile, and improve the load-bearing performance of the entire slide support 100.

[0040] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
