Description

Technical Field

[0001] The invention relates to the technical field of construction, and in particular to a simple sunshade awning for a casement window. Background Art

[0002] Casement windows are a common window structure. With existing outward-opening casement windows, even if it rains lightly, rainwater can easily drift into the room, causing the indoor walls and floors to be soaked by rainwater. The currently available solution is to install a canopy on the outer wall of the window, but most casement windows do not have a canopy on the upper part due to safety, beautiful building facades, and reduced construction costs. Moreover, the current canopies need to be constructed on the outer wall, which is not easy to install and has the safety risk of falling off and injuring people, so they are not suitable for ordinary families. This results in casement windows being closed most of the time to avoid rainwater infiltration, and natural ventilation is impossible, resulting in energy waste and an uncomfortable indoor environment.

[0003] The Chinese patent with publication number CN115929188A discloses "Shielding device and control method thereof and outward-opening casement window", which records a shielding device for casement window, including a shielding unit and a transmission unit. The shielding unit includes a plurality of shielding members. When the shielding device is in the unfolded state, all shielding members are spaced or overlapped with each other to unfold between the opened window sash and the window frame. Each shielding member can rotate around its own axis to change the gap between two adjacent shielding members. The transmission unit is used to drive the shielding member to rotate. Although it can achieve the purpose of sunshade and rainproof when the window is opened on rainy days, the structure of the shielding device is complicated and requires additional power to drive each shielding member to rotate to achieve opening and closing, which will inevitably increase the cost of the device because it has many components and control devices, which will inevitably lead to reduced reliability of the product and shorten its service life. In addition, when the shielding device is in the folded state, all shielding members overlap with each other, and the shielding device may be messily stored between the closed window sash and the window frame, causing it to get stuck and unable to close the window sash normally. Summary of the invention

[0004] The purpose of the present invention is to provide a simple sunshade canopy for casement windows, so as to shield the casement windows from rain on rainy days, thereby achieving the purpose of ventilation, improving indoor comfort and low-carbon energy saving.

[0005] The purpose of the present invention can be achieved through the following technical solutions.

[0006] A simple sunshade for a casement window comprises a window frame and an outward-opening window sash, and also comprises a deformable rainproof cloth, wherein the rainproof cloth is unfolded into a fan shape, one edge of the rainproof cloth is connected to the top of the window frame, and the other edge is connected to the top of the window sash, a first traction rope is arranged on the arcuate side of the rainproof cloth, and the rainproof cloth is provided with a plurality of evenly distributed supporting bone bars along the radial direction, the ends of each supporting bone bar are movably hinged together by a hinge part, and each supporting bone bar is constructed as an active structure with the hinge part as the rotation center, and a magnet is also fixed on the first traction rope, and the magnet is fixed at the intersection of the first traction rope and each supporting bone bar.

[0007] The rainproof cloth of the present invention forms an adjustable canopy above the window. When the window sash is opened, the rainproof cloth unfolds with the window sash to block rain, which can effectively reduce the infiltration of rain into the room when the casement window is opened outward. The window can also be opened on rainy days to improve the indoor ventilation effect and enhance the comfort of the indoor environment. When the window sash is closed, the rainproof cloth can be rolled up above the window frame, and the magnets provided can prevent the rainproof cloth from being messy when being rolled up.

[0008] The present invention also has the following preferred design:

[0009] The magnet of the present invention is provided with a cross hole, and the first traction rope and the support bone strip are cross-threaded into the cross hole. The support bone strip of the present invention can be a lightweight steel wire, and the rainproof cloth and the support bone strip are sewn together by knitting. The first traction rope is made of a lightweight and highly durable flexible material and is fixed to the arc-shaped edge of the rainproof cloth. At the same time, the support bone strip and the first traction rope cross-thread through the cross hole of the magnet to fix the magnet. The position of each magnet is fixed. When the rainproof cloth is rolled up, the magnetic force generated by the magnet can make the rainproof cloth folded in an orderly manner.

[0010] The magnet of the present invention is spherical, and the magnetic force of the magnet arranged on the first traction rope from the window frame to the window sash decreases gradually, and the size and arrangement spacing of the magnet meet the following requirements:

[0011]

[0012] in,

[0013] D is the diameter of the magnet, in meters: m;

[0014] M is the magnetization intensity, the unit is ampere per meter: A / m;

[0021] g is the acceleration due to gravity, measured in meters per second squared: m / s 2 ;

[0022] L is the total length of the arc side when the tarpaulin is fully unfolded, in meters: m.

[0023] The present invention sets the magnets into a spherical shape, and designs the magnetic force of each magnet according to the distance between the magnets. The supporting bone strips play a major supporting role in the process of unfolding and rewinding the rainproof cloth. Due to the magnetic force between the magnets, the shape change of the rainproof cloth will be more stable and not messy, ensuring that the window can be opened and closed smoothly without clamping the rainproof cloth. At the same time, the interaction between the magnets and the support of the supporting bone strips can also enhance the modeling effect of the rainproof cloth.

[0024] The rainproof cloth of the present invention is also provided with a second traction rope parallel to the first traction rope, so that the unfolding and reeling process of the rainproof cloth can be more orderly.

[0025] Furthermore, magnets are arranged at the intersections of the second traction rope and each supporting bone bar, and the magnetic force of the magnets arranged on the second traction rope in the direction from the window frame to the window sash decreases gradually, so as to better ensure the orderly unfolding and reeling of the rainproof cloth.

[0026] The rainproof cloth of the present invention is a light-proof sunshade rainproof canvas, which can play a sunshade effect.

[0027] The rainproof cloth of the present invention is connected to the wall structure above the window frame, or the rainproof cloth is connected to the upper edge of the window frame. When connected, the edge of the rainproof cloth is connected to the window frame side in a waterproof manner to prevent rainwater from entering.

[0028] The rainproof cloth of the present invention is connected to the upper edge of the window sash, or the rainproof cloth is connected to a connecting piece arranged on the window sash. When connected, the edge of the rainproof cloth is connected to the side of the window sash in a waterproof manner to prevent rainwater from entering.

[0029] The rainproof cloth of the present invention is arranged to be inclined downward from the hinged portion to the first traction rope, which can ensure that rainwater flows out of the window smoothly.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. The rainproof cloth of the present invention forms an adjustable canopy above the window. When the window sash is opened, the rainproof cloth unfolds with the window sash to block rain, which can effectively reduce the rainwater from entering the room when the casement window is opened outward. The window can also be opened on rainy days to improve the indoor ventilation effect and enhance the comfort of the indoor environment. When the window sash is closed, the rainproof cloth can be rolled up above the window frame, and the magnets provided can prevent the rainproof cloth from being messy when being rolled up.

[0032] 2. The present invention sets the magnets into a spherical shape, and designs the magnetic force of each magnet according to the distance between the magnets. The supporting bone strips play a major supporting role in the process of unfolding and rolling up the rainproof cloth. Due to the magnetic force between the magnets, the shape change of the rainproof cloth will be more stable and not messy, ensuring that the window can be opened and closed smoothly without clamping the rainproof cloth. At the same time, the interaction between the magnets and the support of the supporting bone strips can also enhance the modeling effect of the rainproof cloth.

[0033] 3. The present invention is easy to install, and the canopy formed by the rainproof cloth can be automatically adjusted according to the opening position of the window sash, so as to achieve the purpose of shielding rain without affecting the facade effect of the exterior wall, and the structure has high safety and long service life.
