Description

Technical Field

[0001] This utility model relates to the field of casement window technology, specifically a multi-position limiting casement window. Background Technology

[0002] In the construction industry, windows are an indispensable and important component of buildings. Traditional casement windows typically consist of a frame and a sash. The sash is hinged to the frame via hinges or other connecting structures, allowing the window to open and close. However, a common problem with existing casement windows is the lack of a dedicated device for securing the sash. This means the sash can only be fixed in a fully open or fully closed state, and cannot be stably fixed at different swing angles. In practice, users often want the window to be able to stay at different opening angles to achieve varying levels of ventilation and lighting. For example, in light winds, a smaller opening angle is desired to ensure adequate ventilation while preventing strong winds from entering the room; conversely, a larger opening angle is desired when more fresh air is needed. However, due to the lack of an effective limiting and fixing structure, traditional casement windows are easily affected by external wind forces and vibrations after opening, causing the sash to swing and become unstable, unable to maintain the desired angle and causing inconvenience for users. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multi-position limiting casement window, which solves the problem that traditional casement windows lack a means to fix the window sash, making it impossible to fix the window sash at different swing angles.

[0004] To achieve the above objectives, this utility model provides a multi-position limiting casement window, including a window frame and a window sash that swings on the window frame. The window sash includes a glass pane and a frame surrounding the glass pane. The bottom inner wall of the window frame has a movable groove along the length of the window frame. A limiting plate is movably disposed in the movable groove along the swing direction of the window sash. The frame has a limiting groove along the length of the window sash for inserting the end of the limiting plate. A first fixing member is provided in the movable groove for fixing the beginning of the limiting plate after it swings. A plurality of limiting holes are evenly distributed along the length of the frame, and the plurality of limiting holes are all connected to the limiting groove. A second fixing member is provided on the frame for fixing the end of the limiting plate when it is inserted into the limiting groove and positioned below any one of the limiting holes.

[0005] The advantages of adopting the above technical solution are as follows: The matching structure of the limiting plate and the limiting groove in the above technology achieves double fixation through the first and second fixing parts, ensuring that the window sash can withstand external wind force, vibration and other environmental loads without displacement at any selected angle. The above technology constructs a multi-level limiting adjustment system by setting a movable groove at the bottom of the window frame and configuring a limiting plate that can move along the swing direction of the window sash. At the same time, limiting grooves and evenly distributed limiting holes are opened on the window sash frame to cooperate with the end of the limiting plate. This fundamentally breaks through the limitation of traditional casement windows that can only be fixed in the fully open or closed state, allowing the window sash to achieve stable positioning at multiple angles within the swing trajectory. Users can flexibly adjust the opening angle of the window sash according to actual needs, such as indoor ventilation, lighting intensity or wind and rain protection. The window sash can be fixed at a small angle in light wind weather to avoid strong winds from entering, and it can also be fixed at a large angle when a large amount of ventilation is needed, which significantly improves the flexibility and adaptability of window use.

[0006] The present invention further comprises: a fixing hole for communicating with the movable groove on the bottom top wall of the window frame; the first fixing member includes a fixing shaft movably disposed in the fixing hole; a first pull ring for passing through the fixing hole and being pulled out by an external operator is provided on the top of the fixing shaft; a first toothed groove is provided circumferentially on the bottom outer peripheral wall of the fixing shaft; a rotating hole is provided on the bottom wall of the movable groove; a rotating shaft for mates with and is rotatably connected to the rotating hole is provided on the bottom wall of the starting end of the limiting plate; an insertion hole for mates with the fixing shaft is provided on the top wall of the starting end of the limiting plate; the insertion hole is connected to the rotating shaft, and a second toothed groove is provided circumferentially on the inner peripheral wall of the insertion hole for mates with and engages with the first toothed groove when the fixing shaft mates with the insertion hole.

[0007] The advantages of adopting the above technical solution are as follows: The design of the fixed shaft, the first pull ring, and the first and second toothed grooves creates a reliable fixing mechanism at the beginning of the limiting plate. When the user needs to adjust the window sash angle, they only need to pull the first pull ring upwards to disengage the fixed shaft from the limiting plate's insertion hole, allowing the limiting plate to swing freely to adjust its relative position to the window sash frame. After adjustment, releasing the pull ring causes the fixed shaft to fall back under gravity or the reset structure. At this point, the meshing of the first and second toothed grooves forms a stable mechanical lock, preventing the limiting plate from rotating or shifting due to external forces during use. This technology organically combines ease of operation with structural stability, ensuring that the user can fix and unlock the limiting plate with a simple pulling action. Furthermore, the toothed groove meshing mechanism improves the impact resistance of the fixing mechanism, avoiding the loosening problems caused by long-term use of traditional limiting structures.

[0008] The present invention further includes a first return spring connected between the outer peripheral wall of the fixed shaft and the inner peripheral wall of the fixed hole, the first return spring being sleeved on the outer peripheral wall of the fixed shaft.

[0009] The advantages of adopting the above technical solution are: the elastic force of the reset spring in the above technology can ensure that the fixed shaft automatically maintains the upward lifting preparation position in the unlocked state, or continuously applies downward pressure in the locked state, so that the first tooth groove and the second tooth groove always keep tightly engaged, avoiding the loosening of the fixed shaft due to insufficient user operation force or external vibration. The automatic reset function eliminates the tedious steps of manually aligning the tooth grooves in the traditional structure. The user only needs to pull once to complete the unlocking. After releasing, the spring force will automatically lock, which significantly improves the operation efficiency and is especially suitable for the elderly or people with mobility difficulties.

[0010] The present invention further includes: a mating hole penetrating the end of the limiting plate; the second fixing member includes several limiting shafts, each of which corresponds to a certain number of limiting holes and is movably disposed in its corresponding limiting hole; a second pull ring is provided at the top of the limiting shaft for passing through the fixing hole and for external operators to pull; and the end of the limiting shaft is a limiting end for fitting into the mating hole.

[0011] The advantages of adopting the above technical solution are as follows: By setting mating holes at the end of the limiting plate and configuring limiting shafts corresponding one-to-one with the limiting holes as second fixing components, a multi-position precise positioning end locking mechanism is constructed. Each limiting hole corresponds to a specific opening angle of the window sash. The user can pull the second pull ring according to actual needs to pull the limiting shaft out of the current limiting hole, then adjust the window sash to the target angle so that the mating hole at the end of the limiting plate aligns with the corresponding limiting hole. Then, the pull ring is released to allow the limiting shaft to insert into the mating hole and the limiting hole, thereby locking the angle. This design divides the opening angle of the window sash into multiple standardized positions. Each position is positioned by the precise insertion of the limiting shaft and the mating hole, ensuring that the window sash remains stable at any selected position, effectively solving the problems of vague window angle adjustment and inaccurate positioning in traditional windows. At the same time, the insertion structure of the limiting end of the limiting shaft and the mating hole has good shear resistance, which can withstand the weight of the window sash in the open state and the action of external wind force, avoiding window sash shaking or accidental closure due to insecure limiting. Meanwhile, the second pull ring makes the operation of the limit shaft more convenient. Users can easily adjust the gear position on the outside or inside of the window sash without bending over or using tools, thus improving the ease of use.

[0012] The present invention is further provided that: a second return spring is connected between the outer peripheral wall of the limiting shaft and the inner peripheral wall of the limiting hole, and the second return spring is sleeved on the outer peripheral wall of the limiting shaft.

[0013] The advantages of adopting the above technical solution are: the elastic force of the second reset spring in the above technology can ensure that the limiting shaft automatically disengages from the mating hole in the unlocked state, which makes it convenient for the user to quickly adjust the angle of the window sash; while in the locked state, the downward pressure continuously applied by the spring can keep the limiting end of the limiting shaft in close contact with the mating hole, preventing the limiting shaft from loosening and falling off due to vibration or wind.
