Description

Technical Field

[0001] This utility model relates to the field of door and window components technology, and in particular to a lift-up window. Background Technology

[0002] Existing lift-up windows typically feature a movable sash on one side. The movable part of this sash usually employs a spring or mechanical transmission structure to assist opening and closing, using pre-tensioning or other methods to help the user operate the sash's raising and lowering. These devices are often integrated into the longitudinal mounting groove of the window frame, using a sliding rail and connectors to transmit power. Some designs also incorporate windproof latches or limiting devices to enhance stability. However, the movable part of traditional movable sashes is directly embedded inside the longitudinal mounting groove, making it prone to wear, corrosion, or fatigue fracture after prolonged use, leading to functional failure. Furthermore, the longitudinal mounting groove, responsible for the up-and-down opening and closing of the sash, is designed in a U-shape. Therefore, space constraints often arise when replacing a damaged movable part, frequently requiring destructive disassembly. This destructive disassembly process can easily deform or damage other components, such as the mounting groove, resulting in abnormal noises during the sash's opening and closing. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a lift-up window that solves the technical problem that the movable part of the movable glass sash in existing lift-up windows is difficult to replace.

[0004] A lift window according to an embodiment of the present utility model includes a window frame and a movable glass sash disposed within the window frame and movable up and down along the window frame. The window frame has a mounting groove on one side of its two height sides. The mounting groove has a U-shaped cross-section. A track is provided near the top of the mounting groove. The movable glass sash is installed in the mounting groove. A movable part is provided between the movable glass sash and the track.

[0005] The mounting groove has a recess in the center, and the bottom center of the track has a slot, which is fixed in place by engaging the recess.

[0006] The movable part of the movable glass fan includes a fixed part and a movable part, as well as an elastic element connecting the fixed part and the movable part. The fixed part is installed in a slot, the movable part is fixed on the movable glass fan and is arranged on the extension line of the slot, and the elastic element is a spring coil structure. The elastic element is wound inside the fixed part, and one end of the elastic element is led out and connected to the movable part.

[0007] The technical principle of this utility model is as follows: When disassembly is required, first loosen the connection between the movable glass fan and the movable component, then move the movable glass fan to the bottom of the mounting groove, and then loosen the screws connecting the track and the mounting groove, i.e. the groove and the slot position. At this time, the track can be removed to replace the movable part of the movable glass fan.

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] Example 1

[0025] like Figure 1-2 The lift window shown includes a window frame 1 and a movable glass sash 3 that can move up and down along the window frame. The window frame 1 has a mounting groove 11 on one side of its two height sides. The mounting groove 11 has a U-shaped cross-section. A track 2 is fixed to the mounting groove 11 near the top position with screws. The movable glass sash 3 is installed in the mounting groove 11 and can slide up and down along the mounting groove 11. A movable part 31 is installed between the movable glass sash 3 and the track 2.

[0026] The movable part 31 of the specific movable glass fan 3 includes a fixed part 311, a movable part 312, and an elastic member 313 connecting the fixed part 311 and the movable part 312. The elastic member 313 is a spring coil structure. The elastic member 313 is wound inside the fixed part 311, and one end of the elastic member 313 is led out and connected to the movable part 312.

[0027] The mounting slot 11 has a groove 111 at its center, and the bottom center of the track 2 has a slot 21. The slot 21 is inserted into the groove 111 and fixed with screws. The fixing component 311 is screwed into the slot 21. The moving component 312 is fixed on the moving glass sash 3. The moving component 312 is set on the extension line of the slot 21. The moving component 312 can move along the track 2. That is, the elastic element 313 always gives the moving glass sash 3 an upward pulling force, reducing the force required to manually move the moving glass sash 3.

[0028] Example 2

[0029] like Figure 3As shown, the difference between this embodiment and embodiment 1 is that: V-shaped elastic pieces 22 are provided on both sides of the track 2, and the two V-shaped elastic pieces 22 are in close contact with the inner wall of the mounting groove 11. Sliding grooves 23 are provided on both sides of the track 2, and the positions of the sliding grooves 23 and the V-shaped elastic pieces 22 correspond. Rollers 24 are evenly distributed in the sliding grooves 23. When the movable glass fan 3 slides into the track 2, the rollers 24 are located on both sides of the movable glass fan 3, ensuring that the movable glass fan 3, the track 2 and the mounting groove 11 are tightly connected.

[0030] The sliding groove 23 is integrally formed with flanges 231 that are close to each other. The roller 24 includes a roller shaft 241 and a wheel portion 242 passing through the roller shaft 241. The two ends of the roller shaft 241 are stuck between the two flanges 231, and the wheel portion 242 is in close contact with the movable glass fan 3.

[0031] like Figure 4 As shown, the sliding groove 23 has plugs 232 at both ends to restrict the roller 24 within the sliding groove 23.

[0032] In this specific embodiment, each mounting slot 11 is provided with two tracks 2, each track 2 being equal to the height of the movable glass fan 3. The top of the upper track 2 is provided with a fixing component 311, while the slot 21 of the lower track 2 is used to accommodate the movable component 312. That is, the track 2 replaces the original limiting device for the movable glass fan 3.

[0033] Furthermore, compared to Embodiment 1, there is no need to connect the mounting groove 11 and the track 2 with screws. The connection is achieved by moving the glass fan 3 to press the roller 24, the roller 24 to press the track 2, and the V-shaped elastic sheet 22 of the track 2 to press the mounting groove 11.

[0034] Example 3

[0035] like Figure 5 As shown, the difference between this embodiment and embodiment 2 is that: a wave elastic strip 211 is fixed at the bottom of the slot 21, and a protrusion 32 is fixed on the movable glass fan 3. The protrusion 32 is in close contact with the wave elastic strip 211. That is, the use of the protrusion 32 in conjunction with the wave elastic strip 211 can prevent the movable glass fan 3 from moving down too quickly.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
