Description

Technical Field

[0001] This utility model relates to the field of building door and window technology, specifically to a device for preventing derailment of a lifting window. Background Technology

[0002] Currently, lift windows are widely used in buildings due to their advantages such as large opening area and good ventilation. However, in actual use, lift windows pose a risk of derailment. When the rollers of the lift window malfunction, the track deforms, or it is subjected to external impact, the sliding sash can easily detach from the track, causing window damage and potentially injury to people. Existing anti-derailment measures for lift windows are often inadequate and cannot effectively prevent derailment accidents. Therefore, a reliable anti-derailment device for lift windows is needed to solve this problem. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a device to prevent derailment of lifting windows, thus solving the problems mentioned in the background section.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, this utility model provides the following technical solution: a derailment prevention device for a lift-up window, applied to a lift-up window. The lift-up window includes a window frame and a movable sash. A set of variable track is provided on the side frame of the window frame, and a set of roller plates is provided on one side of the movable sash. Rollers are rotatably mounted on the roller plates, and the rollers are slidably connected within the variable track. The derailment prevention device includes an anti-derailment top component and an anti-derailment track. The anti-derailment top component is installed on one side of the movable sash, and the anti-derailment track is installed on the side frame of the window frame. The anti-derailment top component is adapted within the anti-derailment track, thus forming an anti-derailment protection for the movable sash.

[0007] Preferably, the track changing section includes a lower straight rail and an upper inclined rail, and the anti-detachment track is on the same vertical line as the straight rail of the lower track changing section to ensure proper fit between the anti-detachment top component and the anti-detachment track.

[0008] Preferably, the anti-detachment top component is composed of a support plate, two torsion springs, a central shaft, and a pendulum. The support plate has a pendulum receiving cavity, and the two torsion springs are respectively placed between the pendulum and the support plate. Circular holes are respectively formed on the pendulum receiving cavity and the corresponding pendulum. The central shaft is inserted into the circular holes of the support plate and the pendulum, so that the pendulum is hinged within the pendulum receiving cavity. A protruding cylinder is provided on the side of the pendulum near the anti-detachment track for interacting with the anti-detachment track to achieve the anti-detachment function.

[0009] Preferably, the pendulum receiving cavity has openings on both sides, and the pendulum and the torsion springs on both sides are placed in the openings. The torsion springs are sealed and fixed to ensure the installation stability and reliability of the torsion springs.

[0010] Preferably, the pendulum receiving cavity is provided with a torsion spring arm groove, one arm of the torsion spring is fixed to the pendulum, and the other arm is fixed inside the pendulum receiving cavity, so that the torsion spring can provide a stable restoring force for the pendulum.

[0011] Preferably, the anti-derailment track has a notch at its upper end, and a track hook is provided at the end corresponding to the pendulum receiving cavity.

[0028] This utility model embodiment provides a device to prevent a lifting window from derailing, such as... Figure 1-10 As shown, it includes an anti-detachment top component 51 and an anti-detachment track 52, and is applied to a lift window. The lift window includes a window frame 1 and a movable sash 2. The side frame 11 of the window frame 1 is provided with a set of variable track 3. A set of roller plate 4 is provided on one side of the movable sash 2. Rollers are rotatably mounted on the roller plate 4 and the rollers are slidably connected in the variable track 3.

[0029] The anti-detachment top piece 51 is installed on one side of the movable sash 2, and the bearing plate 511 is installed on one side of the movable sash 2 via the connecting plate 6. The anti-detachment track 52 is installed on the side frame 11 of the window frame 1, and is on the same vertical line as the straight rail 31 of the lower variable track track 3. The anti-detachment top piece 51 is adapted to the anti-detachment track 52 to form the anti-detachment protection for the movable sash 2.

[0030] like Figure 2 and Figure 3As shown, the anti-detachment top component 51 is composed of a support plate 511, two torsion springs 512, a central shaft 513, and a pendulum 514. The support plate 511 has a pendulum receiving cavity 515, and the two torsion springs 512 are respectively placed between the pendulum 514 and the support plate 511. The pendulum receiving cavity 515 and the corresponding pendulum 514 each have a circular hole 516. The central shaft 513 is inserted into the circular hole 516 of the support plate 511 and the pendulum 514, so that the pendulum 514 is hinged within the pendulum receiving cavity 515. The pendulum 514 has a protruding cylinder 517 on the side near the anti-detachment track 52.

[0031] like Figure 3 As shown, the pendulum receiving cavity 515 has openings 518 on both sides. The pendulum 514 and the torsion springs 512 on both sides are placed in the openings 518 and are fixed with glue. The pendulum receiving cavity 515 has a torsion spring arm groove 519. One arm of the torsion spring 512 is fixed to the pendulum 514, and the other arm is fixed in the pendulum receiving cavity 519.

[0032] like Figure 4 As shown, the anti-detachment track 52 has a notch 521 at its upper end, and a track hook 522 is provided at one end corresponding to the pendulum receiving cavity 515.

[0033] like Figure 5 and 6 As shown, this anti-derailment device is installed on a conventional lift window. The anti-derailment device consists of two parts: an anti-derailment top component 51 and an anti-derailment track 52. The anti-derailment top component 51 is installed below the upper roller plate 4 and is connected to one side of the movable sash 2 by a connecting plate 6. The anti-derailment track 52 is installed on the side frame 11 above the lower inclined rail 32 adjacent to the conventional track.

[0034] If the regular rollers of the window sash suddenly derail abnormally during operation, the window sash will tilt inward. At this time, the anti-detachment top piece 51 will also tilt inward, and the protruding cylinder 517 on the pendulum 514 will hit the side of the anti-detachment track 52 with the track hook 522. At this time, the anti-detachment structure will take over from the side rollers of the window sash to forcibly fix the window sash and prevent it from tilting outward.

[0035] like Figure 7-10 As shown, the anti-derailment device is ineffective when the window is operating normally and does not derail. The window's operation at this time is as follows:

[0036] When the window is closed, the anti-detachment ceiling component 51 is far from the anti-detachment track 52;

[0037] When the window is opened in the first stage, the anti-detachment top piece 51 enters the anti-detachment track 52 through the notch 521 of the anti-detachment track 52 without collision.

[0038] In the second stage of opening the window, the pendulum 514 in the anti-detachment top component 51 touches the lower inclined rail 32, and the interaction force causes the pendulum 514 to swing at a certain angle.

[0039] When the window is opened to the third stage, the pendulum 514 of the anti-detachment ceiling component 51 is completely higher than the inclined rail 32.

[0040] In the fourth stage of window opening, the pendulum 514 of the anti-detachment top component 51 passes through the lower inclined rail 32 and is rebounded to its initial state by the torsion spring 512 inside the component.

[0041] Working principle: When the anti-derailment device for the lifting window is in use, the anti-derailment top component 51 moves together with the movable sash 2. Under normal conditions, the anti-derailment top component 51 moves smoothly within the anti-derailment track 52, without affecting the normal opening and closing of the window. When derailment occurs, the pendulum 514 of the anti-derailment top component 51 interacts with the track hook 522 of the anti-derailment track 52 under the action of the torsion spring 512, preventing the movable sash 2 from continuing to tilt outward, thereby achieving the anti-derailment function.

[0042] In summary, this anti-derailment device for lifting windows has a simple structure and good anti-derailment effect, which can effectively improve the safety and reliability of lifting windows and has broad market application prospects.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
