Description

Technical Field

[0001] This utility model relates to the field of door and window accessories technology, specifically to a window rain cover device designed for temporary ventilation and formaldehyde removal after decoration. It is suitable for short-term ventilation cycles of 3 to 12 months, can be quickly removed after moving in, and is compatible with various window types such as sliding windows and casement windows. Background Technology

[0002] After home renovation, continuous ventilation is necessary to remove harmful gases such as formaldehyde. However, if windows are not closed promptly during rainy weather, rainwater can easily enter the room, causing damp floors, moldy walls, and even damaging furniture, directly interfering with the formaldehyde removal process. Existing rain-proofing solutions have significant drawbacks: most fixed awnings require drilling for installation, damaging walls or window frames, and are mostly made of metal or glass, resulting in high costs and unsuitability for short-term use; simple plastic rain shelters lack a supporting structure, are easily deformed by wind, and only block frontal rain, allowing side rain to seep in; some temporary devices have poor compatibility, requiring replacement when windows are changed. Therefore, the market urgently needs a short-term window rain-proofing device that requires no drilling, has wide compatibility, provides reliable rain protection, and is inexpensive. Summary of the Invention

[0003] The purpose of this utility model is to provide a window rain cover device to solve the problem of temporary rain protection when opening windows for ventilation, and to achieve the core requirements of "no-drill installation, adaptable to multiple window types, and reusable".

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A window rain-proof device includes a rain-proof component (2), a support assembly (1), and two fixing clips (3). The structure and cooperation relationship of each component are as follows:

[0006] 1. Rain shelter component (2): Made of flexible waterproof material, preferably PVC coated fabric or waterproof canvas. The rain shelter component has two opposite ends along the width direction (adapted to the window opening width) and two opposite ends along the length direction. The size can be customized according to the window opening width (normal range 60-120cm). The length direction is divided into indoor and outdoor parts.

[0007] 2. Supporting components (1): including malleable supporting units (such as bendable galvanized metal strips, fiberglass rods with the characteristic of "automatic recovery of the original shape after bending") or at least two rigid supporting units (such as rigid plastic strips, solid wood strips). The malleable supporting units are fixed to the opposite ends of the width direction of the rain shelter component (2) by sewing or gluing, and extend along the length direction of the rain shelter component (2); their shape can be slightly adjusted according to the curvature of the window frame to adapt to irregular window frames, and the elastic reshape material can be quickly restored after being stored. The rigid supporting units can provide stronger wind resistance and prevent rainwater from accumulating due to the drooping of the rain shelter component due to wind force; at the same time, the supporting components (1) have a certain thickness (section thickness 5-10mm), which can directly serve as a side water-blocking structure to prevent rainwater from seeping in from the side of the rain shelter component.

[0008] 3. Two fixing clips (3): Made of stainless steel or aluminum alloy with rust-proof surface treatment. The two fixing clips are respectively set at opposite ends of the width direction of the rain shelter component (2), and are integrally formed or separately connected with the support component (1); the fixing clip includes two oppositely arranged support parts, forming an adjustable clamping space of 40-100mm between the support parts, which can be directly clamped to the window frame or window sash without drilling. At least one of the two support parts of the fixing clip has a threaded through hole (31) for use with a hand screw. Tightening the screw can reduce the clamping space and ensure that the device is not loose. When disassembling, simply loosen the screw in the opposite direction.

[0009] 4. Rainproof Optimization Design: At least one end of the fixing clip (3) and the rainproof component (2) along the length direction is provided with a preset distance in the vertical and horizontal directions, so that the rainproof component is slightly inclined (slope ≤ 5°). This slope can guide rainwater to flow quickly to the outside and avoid accumulation, and will not block ventilation due to excessive tilt angle. If the window height is too high, the number of installations can be increased, for example, one can be installed in the middle and one at the bottom of the window.

[0010] 5. Side rain shelter structure: At least one side rain shelter (21) can be added to one end of the rain shelter component (2) in the width direction. The side rain shelter (21) and the rain shelter component (2) are integrally formed or detachably connected. When unfolded, it can cover the gap on the side of the window and further block the side rain. One end of the side rain shelter (21) in the length direction is connected to at least one side support component (211). The side support component (211) is a lightweight metal rod with a diameter of 5-8mm or the above-mentioned malleable material rod. It can be inserted into the cloth bag preset in the side rain shelter to prevent the side rain shelter from being blown up by the wind.

[0011] The beneficial effects of this utility model are as follows:

[0012] • Ease of installation: No drilling is required. It can be directly clamped to the window frame / window sash with the fixing clips and hand-tightened screws. Installation can be completed without tools and can be done by one person in 1-2 minutes. If the window is too high, it can be installed in multiple positions, and the operation is still simple.

[0013] • Wide adaptability: The width of the rain-shielding component is compatible with the opening width of the window, and it can be adapted to windows of different widths and types. The side rain-shielding parts can be added or removed as needed; if the window height is too high, the number of installations can be increased.

[0014] • Rainproof reliability: The slightly tilted structure, side water blocking of the support components, and side rain shield provide triple protection, blocking rainwater from the front and sides, and preventing rainwater from seeping into the room during moderate rain.

[0015] • Economy and reusability: The core components are low-cost, and the metal fixing clips and support components can be reused. The elastic, reversible, and malleable material is easy to store and quick to restore. When changing houses or windows, only the rain cover components need to be replaced.
