[0002] The sliding structure of doors and windows results in poor sealing, making them unsuitable for environments with high requirements. To address this, some sliding doors and windows with lateral pressure sealing have emerged on the market. After sliding closed, these doors and windows can be gradually moved laterally towards the window frame by turning the handle, and the sealing strip on the door or window presses tightly against the frame, thus improving the sealing performance when closed.

[0003] The sliding roller mechanism of a side-pressure window can maintain stable sliding within the guide rail of the window frame when the door or window is closed to the window frame, with the cooperation of the sliding components. To ensure its transmission stability, the existing sliding roller mechanism structures are relatively complex, occupying a large area between the window frame and the window sash, which is not conducive to the tight closure of the window frame and window sash, as well as aesthetics.

Detailed Implementation

[0021] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model aims to provide a pulley mechanism for a side-press window. By installing this pulley mechanism between the window frame and the window sash, and utilizing the cooperative design of the pulley assembly and the sliding assembly, the pulley assembly can be stably slidably connected within the window frame during the side-pressing process of the window sash. Furthermore, by designing an clearance groove, the sliding assembly is recessed as much as possible into the pulley assembly, effectively reducing the overall height of the mechanism, minimizing the space occupied between the window sash and the window frame, improving sealing performance, and offering the advantages of compact structure, smooth operation, and aesthetic appeal.

[0023] The following is in conjunction with the appendix Figure 1-5 The present invention provides a detailed description of a pulley mechanism for a side-pressure window according to an embodiment of the present invention: like Figure 1 As shown, the pulley mechanism includes a pulley assembly 1 and a sliding assembly 2. The pulley assembly 1 is used to install on the window frame, while the sliding assembly 2 is used to install on the window sash. The cooperation between the two ensures the stability of the side-pressure window during use.

[0024] Specifically, such as Figure 2 As shown, the pulley assembly 1 includes a pulley frame 11 and sliding wheels 12. The pulley frame 11 provides a mounting base for the sliding wheels 12. In this embodiment, two sliding wheels 12 are used (the specific number of sliding wheels is not limited). The two sliding wheels 12 are symmetrically mounted on both sides of the pulley frame 11 and are used to slide onto the window frame profile guide rail. Furthermore, the pulley frame 11 is provided with a clearance groove 111, which cooperates with the sliding assembly 2 to allow the sliding assembly 2 to sink between the two sliding wheels 12, thereby reducing the overall height of the pulley mechanism.

[0025] Continue to refer to Figure 2 As shown, the sliding assembly 2 includes a sliding seat 21 and a sliding bracket 22. The sliding seat 21 is used to connect to the window sash and is provided with a first sliding part 210. The sliding bracket 22 is used to connect to the pulley bracket 11 and is provided with a second sliding part 220. The first sliding part 210 and the second sliding part 220 are slidably engaged so that the sliding seat 21 and the sliding bracket 22 can slide relative to each other and prevent the sliding bracket 22 from deflecting under force.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment, the sliding seat 21 includes a base plate 211 and a side plate 212. The base plate 211 has a rectangular plate structure, and the side plate 212 has a long strip structure. The side plate 212 is oriented along the sliding direction of the sliding wheel (i.e., Figure 2 The sliding bracket 22 (in the X direction) is arranged on both sides of the base plate 211 to jointly form a U-shaped sliding seat. Accordingly, the sliding bracket 22 is located in the U-shaped area of ​​the sliding seat 21, so that it can move relative to the sliding seat 21 in the width direction of the window sash within the U-shaped area.

[0027] Understandably, the U-shaped design of the sliding seat 21 confines the sliding bracket 22 between the two side plates 212, allowing it to move only along the width of the window sash and not along its length. This prevents lateral displacement of the sliding bracket 22 and ensures stability during movement. Furthermore, in this embodiment, the side plate 212 corresponds to the clearance groove 111, allowing the side plate 212 to be at least partially located within the clearance groove 111, thereby reducing the overall height of the pulley mechanism.

[0028] In the above embodiments, preferably, the thickness and material of the base plate 211 and the side plate 212 are the same, for example, both are made of 1-5mm metal plates, preferably 2mm-3mm stainless steel plates, to ensure that the sliding seat 21 maintains structural stability when bearing the load of the pulley assembly. Specifically, the metal plates can be processed into shape by stamping or bending processes.

[0029] Continue to refer to Figure 2 and Figure 4 As shown, the bottom of the sliding frame 22 is connected to the pulley frame 11 via a connecting shaft 10, and the top of the sliding frame 22 is used for sliding connection with the sliding seat 21. Specifically, the sliding frame 22 includes a sliding plate 221 and a connecting plate 222. The sliding plate 221 has a rectangular plate structure, and sliding grooves 220 are respectively formed at both ends of the sliding plate 221. These sliding grooves 220 are the aforementioned second sliding portion 220. Correspondingly, a sliding member 210 is fixed on the bottom plate 211 of the sliding seat 21. This sliding member 210 is the aforementioned first sliding portion 210. Thus, through the sliding engagement of the sliding member 210 and the sliding groove 220, the sliding connection between the sliding frame 22 and the sliding seat 21 is achieved, allowing the sliding frame 22 to slide relative to the sliding seat 21 in a direction perpendicular to the pulley (i.e.,...). Figure 2 It moves back and forth in the Y direction.

[0030] Furthermore, preferably, such as Figure 5 As shown, the sliding member 210 includes a sliding column 2101 and a roller 2102. The sliding column 2101 is fixed to the inner surface of the base plate 211 and extends towards the sliding frame 22 into the sliding groove 220. The roller 2101 is rotatably sleeved on the sliding column 2101 and contacts the inner wall of the sliding groove 220. Thus, the rolling engagement between the roller 2102 and the inner wall of the sliding groove 220 reduces the friction between the sliding member 210 and the sliding groove 220, improving the convenience of relative movement.

[0031] Continue to refer to Figure 2 As shown, the two connecting plates 222 slide in a direction perpendicular to the sliding wheel (i.e., Figure 2The Y-direction of the sliding plate 222 is set on both sides of the sliding plate 221, and the corresponding positions of the two connecting plates 222 are provided with connecting holes 2221. The pulley frame 11 is also provided with through holes 112 at the corresponding positions of the connecting holes 2221. The connecting shaft 10 passes through the connecting holes 2221 and through holes 112 of the first connecting plate 222 and the connecting holes 2221 of the second connecting plate 222 in sequence, thereby connecting the bottom of the sliding frame 22 to the pulley frame 11.

[0032] In this embodiment, preferably, the base plate 211 extends at both ends along the thickness direction of the window sash with positioning and mounting portions 213, and the positioning and mounting portions 213 are provided with fasteners 214, which are used to fix the base plate 213 to the window sash. Specifically, the positioning and mounting portions 213 are provided with fastening holes 2131, and the fasteners 214 are fixed inside the window sash profile after passing through the fastening holes 2131.

[0033] In this embodiment, the fasteners 214 are located at both ends of the base plate 211 along the thickness direction of the window sash, and near the junction area between the base plate 211 and the side plate 212. This shortens the length of the base plate 211, reducing the occupied area, and also disperses the stress between the base plate 211 and the side plate 212, thereby strengthening the base plate 211 and the side plate 212 and preventing deformation. The base plate 211 is fixed to the top or bottom edge of the window sash by the fasteners 214. The side plates 212 on both sides extend perpendicularly to the base plate 211 to form a U-shaped structure. The opening side of the U-shaped structure faces the outside of the window sash, and the sliding bracket 22 is embedded in the opening groove and slides along the thickness direction.

[0034] In the above embodiment, preferably, the base plate 211 of the sliding seat 21 is provided with a positioning protrusion 215, which is used to insert into the window sash profile to realize the pre-positioning of the sliding seat and the window sash profile, thereby improving the convenience of installation.

[0035] Furthermore, it is understood that in this embodiment, the sliding seat 21 can be used to connect to the top edge of the window sash so that the sliding bracket 22 is connected to the upper pulley assembly. The sliding seat 21 can also be used to connect to the bottom edge of the window sash so that the sliding bracket 22 is connected to the lower pulley assembly. The specific installation can be adapted as needed, and no specific limitation is made here.

[0036] Based on the above embodiments, this utility model embodiment also provides a side-pressure window, including a window sash and a window frame, wherein the aforementioned pulley mechanism is provided between the window sash and the window frame.
