A light leakage-proof and noise reduction vertical blind upper rail

Abstract

This invention discloses a light-leakage-preventing and noise-reducing upper track for Venetian blinds, belonging to the field of Venetian blind technology. It includes: an upper track profile with an internal receiving cavity; a cord winder detachably connected to the receiving cavity; an upper track pull bracket snapped onto the top of the upper track profile; and an upper track cover snapped onto the side of the upper track profile. Sound-insulating cotton is placed between the upper track cover and the upper track profile. This invention solves the problem that while existing Venetian blinds can adjust light and create privacy, and are practical, their blade design emphasizes vertical opening and closing, leaving gaps between the top and the ceiling or window frame. In strong sunlight, this allows light to leak in, creating glaring light bands that disrupt the indoor lighting atmosphere, affecting rest and work, and providing a poor experience for people sensitive to light. Furthermore, the motor generates noise during operation, severely reducing the user's quality of life and comfort.

Description

Technical Field

[0001] This invention belongs to the field of Venetian blind technology, and particularly relates to a Venetian blind upper track that prevents light leakage and reduces noise. Background Technology

[0002] The top track of a Venetian blind is the core load-bearing and control component. It is a rectangular metal or plastic box that integrates the transmission system and mounting structure.

[0003] While existing Venetian blinds offer some practicality in regulating light and creating privacy, their slat design often focuses on vertical opening and closing to address issues like light leakage from above and noise interference. When sunlight is strong, light pours down through the gaps between the blinds and the ceiling or window frame, creating glaring streaks that not only disrupt the overall lighting atmosphere of the room but can also affect people's rest or work. This is especially true for those who are sensitive to light, as the light leakage from above significantly impacts their user experience. Furthermore, the motors that operate the blinds generate noise, affecting the user's quality of life and comfort. Summary of the Invention

[0004] The purpose of this invention is to address the problem that while existing Venetian blinds can regulate light and create private spaces and are practical, their blade design focuses on vertical opening and closing, leaving gaps between the top and the ceiling or window frame. When the sunlight is strong, light leaks in, forming glaring light bands that disrupt the indoor lighting atmosphere, affect rest and work, and provide a very poor experience for people who are sensitive to light. Moreover, the motor also makes noise during operation, which seriously reduces the quality of life and comfort of users. Therefore, this invention proposes a light-leakage and noise-reducing Venetian blind top track.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a venetian blind upper track for preventing light leakage and reducing noise, comprising:

[0006] The upper rail profile has a receiving cavity inside;

[0007] A rope winder, which is detachably connected to the receiving cavity;

[0008] The upper rail pull bracket is snapped onto the top of the upper rail profile;

[0009] The upper rail cover plate is snapped onto the side of the upper rail profile, and sound insulation cotton is installed between the upper rail cover plate and the upper rail profile.

[0010] Furthermore, the top of the aforementioned rope winder is provided with several claws, and the inner wall of the upper rail profile is provided with several limiting claws, with the claws engaging with the limiting claws.

[0011] Furthermore, the top of the aforementioned upper rail profile is provided with an upper rail fixing rib, and several first locking claws are provided on both sides of the upper rail pull bracket, the first locking claws being engaged with the upper rail fixing rib.

[0012] Furthermore, the upper rail profile is provided with several second locking claws on its side end, and the upper rail cover is provided with several third locking claws, with the second locking claws correspondingly locking onto the third locking claws.

[0013] Furthermore, the enclosure between the aforementioned upper rail profile and upper rail cover forms a filling groove, and sound insulation cotton is filled into the filling groove.

[0014] Furthermore, the top of the aforementioned upper rail cover is provided with a light-blocking strip groove, and the light-blocking strip is installed in the light-blocking strip groove.

[0015] Furthermore, an inwardly inclined light-shielding plate is provided at the bottom of the aforementioned upper rail cover.

[0016] This invention provides a light-leakage and noise-reducing upper rail for Venetian blinds. Several claws are installed at the top of the rope winder, which engage with several limiting claws on the inner wall of the upper rail profile. This connects the rope winder to the upper rail profile. For disassembly, the rope winder can be easily removed by prying the claws. Simultaneously, an upper rail pull bracket is installed at the top of the upper rail profile, ensuring that the force exerted by the motor during operation is absorbed by the rigid structure of the upper rail profile and the upper rail pull bracket, preventing loosening and improving the overall stability of the upper rail structure. Sound insulation cotton is filled between the cover plate and the upper rail profile to solve the friction noise between the upper rail profile and the upper rail cover plate, as well as the noise generated by the rotation of the motor and the rope winder. A light-blocking strip groove is set at the top of the upper rail cover plate. The light-blocking strip is installed in the light-blocking strip groove and will fit tightly against the ceiling or window frame, sealing the gaps like a sealing strip to prevent light from leaking from the top. A downward-extending light-blocking plate is set at the bottom of the upper rail cover plate, which can solve the problem of light leakage after the blades are flipped, greatly improving the user experience and enhancing the user's quality of life.

[0017] Therefore, this embodiment has the following advantages compared to the prior art:

[0018] A new type of light-leakage and noise-reducing Venetian blind top track solves the problem that while existing Venetian blinds can adjust light and create private spaces and are practical, their blade design focuses on vertical opening and closing, leaving gaps between the top and the ceiling or window frame. When the sunlight is strong, light leaks in, forming glaring light bands that disrupt the indoor lighting atmosphere, affect rest and work, and provide a very poor experience for people who are sensitive to light. In addition, the motor also makes noise when running, which seriously reduces the quality of life and comfort of users. Attached Figure Description

[0032] Example 1

[0033] Please see Figure 1-4 This invention provides a technical solution: a light-leakage-preventing and noise-reducing upper track for Venetian blinds, comprising:

[0034] The upper rail profile 1 has a receiving cavity 2 inside it;

[0035] Rope winder 3, which is detachably connected to the receiving cavity 2;

[0036] Upper rail pull bracket 4 is snapped onto the top of the upper rail profile 1;

[0037] The upper rail cover plate 5 is snapped onto the side end of the upper rail profile 1, and sound insulation cotton is provided between the upper rail cover plate 5 and the upper rail profile 1.

[0038] Specifically, see Figure 1-4The top of the rope winder 3 is provided with several claws 6, and the inner wall of the upper rail profile 1 is provided with several limiting claws 7. The claws 6 are engaged with the limiting claws 7. The four claws on the top cover of the rope winder can be easily and quickly engaged with the upper rail profile, enabling rapid installation and disassembly.

[0039] Specifically, see Figure 1-4 The top of the upper rail profile 1 is provided with an upper rail fixing rib 8, and several first locking claws 9 are provided on both sides of the upper rail pull bracket 4. The first locking claws 9 are engaged with the upper rail fixing rib 8. This achieves a detachable connection between the upper rail pull bracket and the upper rail profile, while also ensuring that the upper rail pull bracket is firmly secured to the upper rail fixing rib. When the curtain is running, the rotation of the motor will not affect the operation of the cord winder, and there is no risk that the upper rail will deform and fall off the mounting bracket.

[0040] This invention provides a light-leakage and noise-reducing upper rail for Venetian blinds. Several claws are installed at the top of the rope winder, which engage with several limiting claws on the inner wall of the upper rail profile. This connects the rope winder to the upper rail profile. For disassembly, the rope winder can be easily removed by prying the claws. Simultaneously, an upper rail pull bracket is installed at the top of the upper rail profile, ensuring that the force exerted by the motor during operation is absorbed by the rigid structure of the upper rail profile and the upper rail pull bracket, preventing loosening and improving the overall stability of the upper rail structure. Sound insulation cotton is filled between the cover plate and the upper rail profile to solve the friction noise between the upper rail profile and the upper rail cover plate, as well as the noise generated by the rotation of the motor and the rope winder. A light-blocking strip groove is set at the top of the upper rail cover plate. The light-blocking strip is installed in the light-blocking strip groove and will fit tightly against the ceiling or window frame, sealing the gaps like a sealing strip to prevent light from leaking from the top. A downward-extending light-blocking plate is set at the bottom of the upper rail cover plate, which can solve the problem of light leakage after the blades are flipped, greatly improving the user experience and enhancing the user's quality of life.

[0041] Therefore, this embodiment has the following advantages compared to the prior art:

[0042] A new type of light-leakage and noise-reducing Venetian blind top track solves the problem that while existing Venetian blinds can adjust light and create private spaces and are practical, their blade design focuses on vertical opening and closing, leaving gaps between the top and the ceiling or window frame. When the sunlight is strong, light leaks in, forming glaring light bands that disrupt the indoor lighting atmosphere, affect rest and work, and provide a very poor experience for people who are sensitive to light. In addition, the motor also makes noise when running, which seriously reduces the quality of life and comfort of users.

[0043] Example 2:

[0044] See Figure 1-4The figure shows a light-leakage and noise-reducing upper rail for a Venetian blind according to Embodiment 2 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: A plurality of second locking claws 10 are provided on the side end of the upper rail profile 1, and a plurality of third locking claws 11 are provided on the upper rail cover plate 5. The second locking claws 10 are correspondingly engaged with the third locking claws 11. This makes the upper rail profile and the upper rail cover plate detachable.

[0045] Example 3:

[0046] See Figure 1-4 The figure shows a light-leakage and noise-reducing upper rail for a venetian blind according to Embodiment 3 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: a filling groove 12 is formed between the upper rail profile 1 and the upper rail cover plate 5, and the sound-insulating cotton is filled in the filling groove 12. This solves both the friction noise between the upper rail profile and the upper rail cover plate, and the noise generated by the rotation of the motor and the rope winder, thus improving the user experience.

[0047] Example 4:

[0048] See Figure 1-4 The figure shows a light-leakage and noise-reducing upper rail for a venetian blind according to Embodiment 4 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: a light-blocking strip groove 13 is provided at the top of the upper rail cover plate 5, and the light-blocking strip is installed within the light-blocking strip groove 13. This solves the problem of light leakage from the top.

[0049] Example 5:

[0050] See Figure 1-4 The figure shows a light-leakage and noise-reducing upper rail for a venetian blind according to Embodiment 5 of the present invention. Based on the above embodiments, this embodiment further improves upon the following technical solution: an inwardly inclined light-blocking plate 14 is provided at the bottom of the upper rail cover 5. This solves the problem of light leakage during the slat rotation process.
