Description

Technical Field

[0001] This invention relates to the field of building component technology, and in particular to a method for preventing mosquitoes and providing ventilation. Background Technology

[0002] As framed, framed building components, window screens and screen doors primarily function to prevent insects from entering the building while maintaining ventilation. The functional component for preventing insects in window screens and screen doors is the mesh. Currently, the mesh size of the mesh on the same window screen or screen door is uniform, which allows for ventilation but does not provide shade.

[0003] Moreover, most current screen windows or screen doors use manual fixing methods, such as using support rods and top screws, which require manual fixing of the position. They cannot automatically connect to the frame when the screen is closed or automatically lock the angle between the screen and the frame when the screen is opened.

[0004] Therefore, a method that prevents mosquitoes and ensures ventilation is needed to solve the above problems. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a method for preventing mosquitoes and providing ventilation, in order to solve the problems in the prior art where the mesh size of the screen window or screen door on the same side is the same, which can play a ventilation role but cannot block the sun, and cannot automatically connect with the frame when the screen window is closed or cannot automatically lock the angle between the screen window and the frame when the screen window is open.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] A method for preventing mosquitoes and providing ventilation utilizes a rotating ventilation and sunshade building component to achieve both mosquito prevention and ventilation in a building. The method includes the following steps:

[0008] A. Install building components;

[0009] B. Prevent mosquitoes and ensure ventilation;

[0010] C. Open the screen window body;

[0011] D. Close the screen window body;

[0012] E. Complete ventilation.

[0013] Furthermore, before installing the building components in step A, the process also includes making a mesh screen, wherein the mesh screen is made with more weft threads in the upper part than in the lower part, and the mesh area in the upper part is smaller than the mesh area in the lower part.

[0014] Furthermore, the area of ​​the upper part accounts for 30%-50% of the total area of ​​the mesh.

[0015] Furthermore, step A, installing the building components, includes: installing the screen mesh onto the screen window body, installing the screen window body onto the column, and causing the bushing to rotate around the spindle.

[0016] Furthermore, step B, mosquito prevention and ventilation, includes: keeping the sliding window on one side of the outer frame and keeping the screen body on the other side of the outer frame.

[0017] Furthermore, step B, mosquito prevention and ventilation, also includes: the screen body is attracted by magnetic pieces set on the two vertical frames, thereby connecting the screen body to the frame.

[0018] Furthermore, step B, mosquito prevention and ventilation, also includes: if the light transmittance of the building components is to be set to the maximum, step C is executed; if ventilation is to be completed, step E is executed.

[0019] Furthermore, step C, opening the screen window body, includes: pushing the screen window body to separate it from the frame.

[0020] Further, step D, closing the screen body, includes: holding the sliding window on one side of the outer frame, rotating the screen body until the screen body is attracted by the magnet.

[0021] Furthermore, step D, closing the screen body, also includes: if ventilation is maintained, step B is executed; if ventilation is not maintained, step E is executed.

[0022] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0023] (1) In the ventilation method of the present invention, turning the handle can drive the latch to slide in the lock groove towards the third spring, while unlocking the stop bar and locking the sliding window to prevent the sliding window from blocking the internal space of the frame and causing poor ventilation; pressing one end of the stop bar so that it presses against the connecting end of the latch, and pushing the latch towards the third spring and compressing the third spring through the arc surface or slope, and continuing to press the stop bar into the lock groove until one end of the stop bar passes the connecting end of the latch, releasing the push on the latch, the latch is popped out by the third spring, and the latch locks the stop bar, thus unlocking the sliding window;

[0024] (2) The upper part of the mesh of the building component of the present invention has more weft threads than the lower part, and the mesh area of ​​the upper part is smaller than that of the lower part. This makes the light transmittance of the upper part of the mesh less than that of the lower part, and the upper part of the mesh can block more sunlight and play a role in sun shading.

[0025] (3) The building components of the present invention have multiple magnetic sheets, which are respectively set on two vertical frames. No matter which vertical frame the screen body approaches, it can be attracted by the magnetic sheet, ensuring that the screen body can maintain connection with the frame.

[0026] (4) When the buckle of the building component of the present invention is rotated, the notch will lock the second locking shaft, and the screen lock can lock the screen body and the frame to prevent the screen body from opening, thus ensuring the safety protection of the building by the building component of the present invention.

[0027] (5) The movable pin of the building component of the present invention can enter the recess of the pin groove, so that the movable pin is connected to the pin groove. The first spring can push the movable pin, so that the movable pin is always connected to the pin groove, thereby locking the bushing and the spindle to prevent the screen body from rotating along the column. When the screen body is rotated and the movable pin is disengaged from the pin groove, the rotating shaft lock can be automatically unlocked. Attached Figure Description

Detailed Implementation

[0040] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0041] Example 1

[0042] A specific embodiment of the present invention, such as Figure 1 As shown, a method for preventing mosquitoes and ventilating (hereinafter referred to as the ventilation method) is disclosed, which uses the building components of Example 2 to prevent mosquitoes and ventilate the building.

[0043] The ventilation method of the present invention includes the following steps:

[0044] Step 1: Making the mesh 7

[0045] The portion of mesh 7 near the top is called the upper part, and the portion near the bottom is called the lower part. Mesh 7 is made such that the upper part has more weft threads than the lower part, and the mesh area of ​​the upper part is smaller than the mesh area of ​​the lower part.

[0046] Preferably, the upper part accounts for 30%-50% of the total area of ​​the mesh 7.

[0047] Step 2: Install building components

[0048] Install the screen 7 onto the screen body, with the screen body perpendicular to the ground. The end furthest from the ground is the top, and the end closest to the ground is the bottom.

[0049] Install the screen body onto the post 1, so that the bushing 2 rotates around the spindle 14.

[0050] Step 3: Keep the shade

[0051] The two sliding windows 11 are connected to the two vertical frames respectively to seal the interior space of the entire frame 3.

[0052] Preferably, the upper part of the mesh 7 is positioned above eye level to block light above eye level. Specifically, the upper part of the mesh 7 is positioned at a height of 1.9 meters or more above the ground.

[0053] Step 4: Prevent mosquitoes and ensure ventilation

[0054] The sliding window 11 is held on one side of the outer frame 3, and the screen body is held on the other side of the outer frame 3, so as to keep the building component of the present invention protected against mosquitoes and provide ventilation.

[0055] Preferably, pulling the handle 16 can cause the locking tongue 17 to slide in the locking groove toward the third spring 21, while simultaneously unlocking the stop bar 10 and locking the sliding window 11 to prevent the sliding window 11 from blocking the internal space of the frame 3 and causing poor ventilation.

[0056] The screen body is attracted by the magnets 4 set on the two vertical frames, thereby connecting the screen body to the frame 3.

[0057] To prevent people outside the building from opening the screen window body, the buckle 83 is rotated, and the notch locks the second locking shaft 82, locking the screen window body and the frame 3 to prevent the screen window body from being opened.

[0058] To set the light transmittance of building components to the maximum, proceed to step 5; to complete ventilation, proceed to step 7.

[0059] Step 5: Open the screen window body

[0060] Rotate the buckle 83 in the opposite direction, the notch disengages from the second locking shaft 82, and the screen lock 8 is unlocked.

[0061] Push the screen body to separate it from the frame 3, thus completing the action of opening the window or door.

[0062] When the rotating screen body is in a position perpendicular to the sliding window 11, the pivot lock is locked, and the building component is set to the maximum light transmittance.

[0063] Preferably, if it is raining, the rainwater directly washes the screen body and rinses the screen mesh 7.

[0064] Preferably, at this time, press one end of the stop bar 10 to press it against the connecting end of the latch 17, push the latch 17 towards the third spring 21 through the arc or slope and compress the third spring 21, continue to press the stop bar 10 into the lock groove until one end of the stop bar 10 passes past the connecting end of the latch 17, release the push on the latch 17, the latch 17 is popped out by the third spring 21, and the latch 17 locks the stop bar 10, thereby unlocking the sliding window 11; connect the two sliding windows 11 to the two vertical frames respectively to seal the internal space of the entire frame 3 and prevent rainwater from entering the building.

[0065] Step 6: Close the screen window body

[0066] Hold the sliding window 11 to one side of the outer frame 3, rotate the screen body, the movable pin 12 disengages from the pin groove 19, the pivot lock unlocks automatically until the screen body is attracted by the magnet 4, and the screen window or screen door is closed.

[0067] If ventilation is maintained, proceed to step 4; if ventilation is not maintained, proceed to step 7.

[0068] Step 7: Complete ventilation

[0069] Close the sliding window 11 and connect the two sliding windows 11 to the two vertical frames respectively to seal off the entire interior space of the frame 3. External air cannot enter the building interior through the building components of this invention, thus completing ventilation.

[0070] Example 2

[0071] Another specific embodiment of the present invention, such as Figure 2 As shown, a rotating ventilation and sunshade building component (hereinafter referred to as the building component) is disclosed to implement the ventilation method of Embodiment 1. It includes a column 1, a frame 3 and a screen body. The two ends of the column 1 are respectively connected to the frame 3, and one end of the screen body is rotatably connected to the column 1. The screen body rotates around the column 1, thereby blocking the gap between the column 1 and the frame 3 and preventing mosquitoes from entering the room.

[0072] Preferably, the screen body can be used as both a screen window and a screen door; however, this invention does not limit this use.

[0073] Preferably, the frame 3 is a rectangular frame, including two horizontal frames and two vertical frames. The horizontal frames are parallel to the ground, the vertical frames are perpendicular to the ground, and the column 1 is set in the middle of the two vertical frames.

[0074] Preferably, a magnetic sheet 4 is provided on the upright frame of the frame 3. The magnetic sheet 4 can attract the screen body and ensure that the screen body can remain connected to the frame 3.

[0075] Preferably, such as Figure 3 As shown, the screen window body includes a window frame 6, a handle 5, and a screen 7. The handle 5 is set on the window frame 6, and each end of the screen 7 is connected to the window frame 6. The handle 5 is used to push and pull the screen window body.

[0076] Preferably, the mesh 7 comprises warp and weft threads, which are interwoven to form a mesh. The screen body is installed perpendicular to the ground, with the end of the screen body furthest from the ground being the upper end and the end of the screen body closest to the ground being the lower end. The portion of the mesh 7 near the upper end is the upper part, and the portion near the lower end is the lower part.

[0077] Preferably, the warp threads extend perpendicular to the ground, and the weft threads extend parallel to the ground. The upper part of the mesh 7 has more weft threads than the lower part, and the mesh area of ​​the upper part is smaller than that of the lower part. This results in less light transmission at the upper part of the mesh 7 compared to the lower part, allowing the upper part of the mesh 7 to block more sunlight and thus providing a sunshade effect.

[0078] Preferably, the upper part accounts for 30%-50% of the total area of ​​the mesh 7.

[0079] To block light above a person's head, the upper part of the screen 7 is positioned above eye level to effectively block light above that level. Specifically, the upper part of the screen 7 is positioned at a height of 1.9 meters or more above the ground.

[0080] Preferably, such as Figure 4 As shown, there are multiple magnetic sheets 4, which are respectively set on the two upright frames. No matter which upright frame the screen body approaches, it can be attracted by the magnetic sheet 4, ensuring that the screen body can maintain a connection with the frame 3.

[0081] Preferably, the building component of the present invention further includes a sliding window 11, which is disposed between two horizontal frames. There are two sliding windows 11, and each sliding window 11 is connected to one of the two vertical frames, thereby sealing off the entire interior space of the frame 3. The sliding window 11 is used for light transmission and wind protection.

[0082] Preferably, the building component of the present invention further includes a rough edge 9, which is provided on the window frame 6 and the column 1. The rough edge 9 has a rough structure and is used to seal the gaps between the screen body and the frame 3, and between the column 1 and the sliding window 11, to prevent mosquitoes from passing through the building component of the present invention.

[0083] Preferably, such as Figure 5 As shown, the building component of the present invention also includes a screen lock 8, which is used to lock the screen body and the frame 3.

[0084] Preferably, the screen lock 8 includes a first locking shaft 81, a second locking shaft 82, and a latch 83. The first locking shaft 81 is mounted on the window frame 6, and the second locking shaft 82 is mounted on the magnetic plate 4. One end of the latch 83 is connected to the first locking shaft 81 and can rotate around the first locking shaft 81. The other end of the latch 83 is a notch that can lock the second locking shaft 82. When the latch 83 is rotated and the notch locks the second locking shaft 82, the screen lock 8 can lock the screen body to the frame 3, preventing the screen body from opening and ensuring the safety protection of the building by the building component of the present invention. When the latch 83 is rotated in the opposite direction and the notch disengages from the second locking shaft 82, the screen lock 8 unlocks, pushes the screen body, and the screen body can separate from the frame 3 to complete the opening of the window or door.

[0085] Preferably, such as Figure 6 and Figure 7As shown, the building component of the present invention also includes a bushing 2 and a spindle 14. The spindle 14 is mounted on the column 1, and the bushing 2 is mounted on the window frame 6. The bushing 2 can rotate along the spindle 14, thereby enabling the screen window body to rotate along the column 1.

[0086] Preferably, the building component of the present invention further includes a pivot lock, which includes a movable pin 12 and a first spring 13. The first spring 13 is disposed on the bushing 2, and the movable pin 12 and the first spring 13 are connected. The first spring 13 enables the movable pin 12 to always remain away from the bushing 2. The spindle 14 is provided with a pin groove 19, which is a recess. The movable pin 12 can enter the recess of the pin groove 19, so that the movable pin 12 is connected to the pin groove 19. The first spring 13 can push the movable pin 12, so that the movable pin 12 always remains connected to the pin groove 19, thereby locking the bushing 2 and the spindle 14 and preventing the screen body from rotating along the column 1.

[0087] Preferably, the first spring 13 can push the movable pin 12 towards the window frame 6, and the pin groove 19 is located in the direction close to the sliding window 11. When the screen body is rotated and the pivot lock is locked, the screen body can be in a state perpendicular to the sliding window 11. At this time, the vertical projection area of ​​the screen body onto the frame 3 is minimized, and the light transmittance of the building component of the present invention is maximized, ensuring that the building achieves maximum lighting. In rainy weather, rainwater can also directly wash the screen body and clean the screen 7.

[0088] Preferably, the portion connecting the movable pin 12 and the pin groove 19 is an arc surface, and the recess in the pin groove 19 is an arc-shaped recess. When the screen body is perpendicular to the sliding window 11, the movable pin 12 automatically falls into the arc-shaped recess; continued pressure is applied to the window frame 6, causing the bushing 2 to rotate around the spindle 14, which can force the movable pin 12 to disengage from the pin groove 19, thereby unlocking the pivot lock. When the screen body is perpendicular to the sliding window 11, the pivot lock can automatically lock; rotating the screen body disengages the movable pin 12 from the pin groove 19, and the pivot lock can automatically unlock.

[0089] Preferably, the column 1 is further provided with a fixing plate 15, which is connected to the column 1. The fixing plate 15 is provided with mounting holes, and screws (not shown in the figure) are driven into the mounting holes to achieve connection with the frame 3.

[0090] Preferably, such as Figure 8As shown, the building component of the present invention also includes a sliding window lock, which is disposed at one end of the column 1. The column 1 is also provided with a lock groove, and the sliding window lock is disposed within the lock groove. The sliding window lock includes a stop bar 10 and a stop bar lock assembly. One end of the stop bar 10 is connected to the column 1 and can protrude from the lock groove to block the sliding window 11; the stop bar 10 can also retract into the lock groove, simultaneously releasing the lock on the sliding window 11; and the stop bar 10 can be connected to and locked by the stop bar lock assembly to prevent the stop bar 10 from protruding from the lock groove, thereby unlocking the sliding window 11.

[0091] Preferably, the sliding window lock further includes a second spring 18, with both ends of the second spring 18 connected to the stop bar 10 and the column 1, respectively. One end of the stop bar 10 is hinged to the column 1, and the stop bar 10 can rotate around the hinge point, thereby extending or retracting into the lock groove. When the stop bar 10 retracts into the lock groove, the second spring 18 is compressed, storing potential energy, and continues to rotate the stop bar 10 until it is connected to the stop bar lock assembly and locked by the stop bar lock assembly; when the stop bar lock assembly releases the lock on the stop bar 10, the second spring 18 can eject the stop bar 10 from the lock groove.

[0092] Preferably, the second spring 18 is a herringbone leaf spring. The herringbone leaf spring occupies a small volume after compression, saving space in the lock groove.

[0093] Preferably, such as Figure 9 As shown, the stop lever lock assembly includes a handle 16, a latch 17, a connecting part 20, and a third spring 21. The handle 16 and the latch 17 are connected via the connecting part 20. The latch 17 and the third spring 21 are disposed within a lock groove, with the handle 16 located outside the lock groove. The third spring 21 is located at one end of the latch 17, and the other end of the latch 17 can be connected to a stop lever 10 to lock the stop lever 10. Moving the handle 16 causes the latch 17 to slide within the lock groove towards the third spring 21, simultaneously unlocking the stop lever 10. Releasing the handle 16 causes the third spring 21 to spring the latch 17 towards the stop lever 10.

[0094] Preferably, the connection end between the latch 17 and the stop bar 10 is an arc surface or a slope. When the stop bar 10 is retracted into the lock groove, one end of the stop bar 10 can press against the connection end of the latch 17. The arc surface or slope pushes the latch 17 towards the third spring 21 and compresses the third spring 21. The stop bar 10 is then retracted into the lock groove until one end of the stop bar 10 passes the connection end of the latch 17, releasing the push on the latch 17. The latch 17 is then ejected by the third spring 21, and the latch 17 locks the stop bar 10, thus unlocking the sliding window lock.

[0095] Preferably, the side wall of the lock groove is provided with flanges (not shown in the figure), there are two flanges, the flanges are provided between the handle 16 and the lock tongue 17, the flanges prevent the lock tongue 17 from disengaging from the lock groove, and ensure that the lock tongue can only slide along the lock groove.

[0096] Preferably, there are two sliding window locks, which are respectively installed at both ends of the column 1 to lock the upper and lower ends of the sliding window 11, ensuring that the sliding window 11 is securely locked.

[0097] In use, the upper part of the screen 7 is positioned above eye level to block light above eye level. Multiple magnetic pieces 4 are respectively installed on the two vertical frames. The screen body can be attracted by the magnetic pieces 4, enabling the screen to be closed. To prevent people outside the building from opening the screen body, rotating the latch 83 causes the notch to engage the second locking shaft 82, locking the screen body to the frame 3 and preventing it from opening. Reverse rotation of the latch 83 causes the notch to disengage from the second locking shaft 82, unlocking the screen body and allowing it to separate from the frame 3, thus opening the window or door. When the screen body is rotated to a position perpendicular to the sliding window 11, the pivot lock engages, maximizing the light transmission of the building component. In rainy weather, rainwater can directly wash the screen body, rinsing the screen 7. Rotate the screen body again, the movable pin 12 disengages from the pin groove 19, the pivot lock automatically unlocks until the screen body is attracted by the magnet 4, closing the screen or screen door; turn the handle 16, causing the latch 17 to slide in the lock groove toward the third spring 21, simultaneously unlocking the stop bar 10 and locking the sliding window 11; press the stop bar 10 to retract it into the lock groove, compressing the second spring 18, continue rotating the stop bar 10 until it connects with the stop bar lock assembly and is locked by the stop bar lock assembly, unlocking the sliding window 11.

[0098] Compared to existing technologies, in this embodiment, the light transmittance of the upper part of the screen 7 is less than that of the lower part, allowing the upper part of the screen 7 to block more sunlight and thus providing a sunshade effect. Multiple magnetic sheets 4 are respectively installed on the two upright frames. The screen body can be attracted to either upright frame, ensuring that it remains connected to the frame 3. The rotating latch 83, when the notch engages the second locking shaft 82, locks the screen body to the frame 3, preventing the screen body from opening and ensuring the building components of this invention provide safety protection for the building. The movable pin 12 can enter the recess of the pin groove 19, connecting the movable pin 12 to the pin groove 19. The first spring 13 pushes the movable pin 12, ensuring that the movable pin 12 remains connected to the pin groove 19. This locks the bushing 2 and the spindle 14 together, preventing the screen body from rotating along the post 1. When the screen body is rotated, the movable pin 12 disengages from the pin groove 19, and the pivot lock can be automatically unlocked. One end of the stop bar 10 is connected to the post 1 and can protrude from the lock groove to block the sliding window 11, thus locking the sliding window lock. One end of the stop bar 10 can press against the connecting end of the latch 17, and push the latch 17 towards the third spring 21 through the arc or slope and compress the third spring 21. Continue to retract the stop bar 10 into the lock groove until one end of the stop bar 10 passes the connecting end of the stop bar 10, releasing the push on the latch 17. The latch 17 is ejected by the third spring 21, and the latch 17 locks the stop bar 10, thus unlocking the sliding window lock.

[0099] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
