Ventilation and vision-blocking curtains

Abstract

This ventilated yet vision-blocking curtain consists of two suspended, spaced-apart fabric strips with raised edges, fitted with a ventilated and vision-blocking flat tube assembly, creating a curtain that provides both front ventilation and visual obstruction. Within the assembly, the wind-blown barriers are semi-circular, with convex, rounded edges at the front and back, and a fabric-embedded snap fastener in the center of the outer wall. A curved partition stands between the left and right wind-blown barriers, its left and right edges also featuring convex, rounded edges, and a reinforcing rib in the center. The top and bottom ends of this three-piece set are sealed and shaped by short, square-shaped retaining materials with snap fasteners at the four corners of the outer wall and at the two ends of the inner wall, forming a "five-in-one" end seal. The fabric strips can be made of coarse-diameter mesh fabric or directly from thickened, denser webbing on both sides. At night, under a healthy environment with good air quality, it protects privacy, allowing for peaceful use of the toilet and sleep, and even saves nearly two months' worth of air conditioning electricity. For smokers, it can also reduce the retention and harm of secondhand smoke.

Description

Technical Field This invention pertains to everyday household items, specifically a curtain. Background Technology

[0001] With high-rise buildings, windows are very close together. At night, with lights in every home, the need for ventilation while blocking views and ensuring privacy is paramount, especially for bedroom and bathroom windows, currently primarily addressed by Venetian blinds. However, these thin aluminum or wooden strips, stacked, raised, lowered, and adjusted using ladder ropes, have the following drawbacks: First, installation is extremely inconvenient. One has to climb up and down, carefully measure the window dimensions, place the order, and then hire someone to drill holes and install it. Second, people still dare not approach the window directly (there are eyes above and below); by the time it's adjusted to a point where outsiders can't see through it, it's essentially become stuffy… Third, even a slight breeze can cause it to become unpredictable, leading to adjustment malfunctions. Often, people get angry, remove, and discard the entire system over a single thin rope! Therefore, the adoption rate of Venetian blinds in homes has remained low. Unfortunately, countless households still use the traditional cloth curtains that open horizontally from side to side, regardless of size or length. They certainly don't obstruct the view, but for ventilation, the horizontal rods hanging the curtains must extend a foot into the room to allow airflow around the edges (rather than allowing air to pass directly in front of the person). However, this still isn't ideal: firstly, the curtains protrude too far from the wall, wasting space and looking unsightly. Secondly, although many weights are added to the bottom of the curtains, in a light breeze they act as a "windbreak," hindering airflow; but in a stronger wind, they either open inwards, exposing the person, or blow outwards, pressing against the window, making ventilation difficult. This forces closing the windows and turning on the air conditioner—increasing electricity bills!

[0002] This invention aims to create a "ventilated and vision-blocking curtain" that allows for frontal ventilation, based on the traditional fabric curtains that are quick to install, easy to open and close from left to right, and simple and reliable. Summary of the Invention

[0003] The technical solution of this invention is as follows: Simply put, a "ventilation and vision-blocking flat tube assembly" with an overall flat tube shape is made and densely embedded in many narrow air vents reserved on the curtain fabric, thus making the curtain a ventilation and vision-blocking curtain. There are various embedding methods. The optimized and quick-to-manufacture solution submitted here is: a ventilation and vision-blocking curtain composed of curtain fabric suspended by rope rods, characterized in that: A. The whole curtain fabric is "divided into parts" and composed of many spaced-apart connecting strips. These intervals are actually air vents and front air passages; the two sides of the connecting strips are made with convex edges for splicing. There are two methods for making them: one is to cut strips from the whole curtain fabric, fold the edges, thicken them, and lock the edges to form a natural and continuous soft convex edge, or to use a stapler to insert several staples to form a discontinuous hard convex edge; the other is to eliminate the need for cutting strips and directly order finished webbing as connecting strips, with the two sides of the webbing being denser and thickened to form convex edges. B, the ventilation and vision-blocking flat tube assembly, is composed of extruded thin sheet profiles, with talcum powder and color powder added to make it opaque. Specifically, it consists of a semi-circular windbreak with convex, rounded edges at the front and back, and a fabric-embedded opening in the middle of its outer wall. A curved partition stands between the left and right windbreaks, its left and right edges also featuring convex, rounded edges, and a reinforcing rib in the middle. The upper and lower ends of this three-piece set are sealed with short, square, retaining profiles with convex openings at the four corners of the outer wall and convex openings at the two middle ends of the inner wall. This "five-in-one" end sealing and shaping completes the entire ventilation and vision-blocking flat tube assembly. It is evident that its "occupancy:ventilation = 2:1," providing half the airflow. Then, the assembly is inlaid between the fabric strips in a "through-the-edge" manner, completing this "ventilation and vision-blocking curtain." This can be further subdivided into two modes: The first is "simple and direct," a "one-step, all-in-one" approach. The bottom of the front panel has anti-fall clips (using various commercially available push clips, through-hole snaps, or nail fasteners), and the entire ventilation and view-blocking flat tube assembly runs almost the entire length. For floor-to-ceiling windows, this nearly three-meter-long assembly, to prevent deformation of the thin profiles due to excessive length, requires not only end seals but also one or two sections inserted and reinforced in the middle to secure the profiles. Hanging eyelets are made at the top of the front panel to complete the hanging, creating a "ventilation and view-blocking curtain" that provides both frontal ventilation and view obstruction. This style is rugged and robust. The second mode breaks down the entire flat tube assembly into "multiple sections connected in sequence," with component lengths ideally between half a meter and one meter, two or three sections forming a unit, in a segmented manner. The perforated windows created by the gaps between components require a bit more work. They need additional covering fabric. One side is sewn onto the connecting strip, inserted into the components, and used to cover the perforated window. The other side is secured with a snap fastener or similar fastener. If this is too much trouble, a covering fabric can be added to the back. Alternatively, a connecting strip can be made from coarse-threaded mesh fabric. With building and window spacing of tens of meters, the grid-like and fragmented silhouettes not only eliminate privacy concerns but also ensure near-full ventilation under obstructed visibility, equivalent to the airflow of a fully open window.

[0004] This curtain has components, so the need for weights is eliminated. Darker colors should be used primarily to avoid bright morning sunlight affecting sleep. For ease of drawing and explanation, the component profiles in the attached diagram appear thicker, estimated at 2-3mm, while the actual extruded profiles are thinner, only about 1mm.

[0005] The beneficial effects of this invention are: First, at night, under the influence of clean air and a healthy environment, privacy is protected, allowing for peaceful use of the toilet and sleep, and saving nearly two months' worth of air conditioning electricity bills. Second, this curtain can accelerate smoke dissipation, reducing the retention and harm of secondhand smoke to smokers, especially their spouses. Third, this component can be connected to form a small, solid "ventilated and visually-blocking rigid panel," and a separate "ventilated and visually-blocking door-within-a-door" style bedroom door can be created. Opening the small door within the door allows for unobstructed airflow with the curtain. In the dead of winter, the small door can be closed, and in the sweltering summer when the air conditioning is on, the small door can also be closed, providing a completely new experience.

Detailed Implementation

[0007] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0008] See Figure 1 A semi-circular windbreak 1 has rounded protrusions 2 extruded at its front and rear edges, and a fabric-embedded opening round buckle 3 extruded in the middle of its outer wall; an arc-shaped partition 4 stands in the middle of the left and right windbreaks, and the left and right edges of the partition 4 are also rounded protrusions 2, with reinforcing ribs 5 in the middle; the two windbreaks and the partition are pushed out together and cut into groups. Figure 2 The retaining profile 6 has round buckles 7 at the four corners of its outer wall and at the two middle ends of its inner wall. The retaining profile is used in very small quantities and is pushed out separately.

[0009] Figure 3 The enclosure profile is formed by surrounding two windbreaks and a central partition, demonstrating the principle of ventilation and visual obstruction: the wind bypasses it, and the line of sight is blocked.

[0010] Figure 4It is a combined ventilation barrier flat tube assembly. It shows that in order to prevent the thin profiles from deforming due to excessive length, the retaining profile 6 is used not only for end sealing, but also one or two retaining profiles 6 must be inserted and reinforced in the middle of the assembly.

[0011] Figure 5 This is a curtain with a "one-stop" design. The two sides of the front panel strip 8 are convex edges 9, and the bottom is equipped with a drop-stop buckle 10 (which should be shown at the bottom of the front panel strip, but the scale is too small to see clearly, so it can only be shown at the top). The top has a hanging buttonhole 11.

[0012] Figure 6 This is a schematic diagram of the "interlocking" segmented curtain. Also shown are the anti-fall limit buckle 10 and the concealing fabric piece 12, sewn onto the front panel strip on one side (sewing point 13), inserted into the components, covering the lattice window, and locked on the other side using a through-type button 14, etc. Furthermore, the front panel strip (only a portion shown) and concealing fabric piece can be made from a coarse-thread mesh fabric 15.

[0013] Figure 7 The windproof enclosure for the components used in the bedroom door-in-door system has a rounded convex shape 16 extruded in the middle of its outer wall. Figure 8 The assembly is a rigid plate ventilation and visual barrier component used for door-in-door applications.
