LT6327B - Airflow-forming structural element of venetian blinds and methods of its attachment - Google Patents

Abstract

Conventional venetian blind system is improved with airflow-forming and upwardly directing forming slats. Forming slats can be implemented as a separate structural element attached to slat-holding vertical cord or they can be formed within the slats themselves. In order to shape airflow-forming structural elements, openings are made in the slats for air to go upwards and the bent plane, which is obtained when making openings, serves as a guide for an airflow. Forming slats of both types can be used in combination for forming airflow. Slats of venetian blinds having a direct optical contact with the sun can be covered with material that increases absorption and release of heat at one side and with material that reflects solar heat on the other. Forming slats direct airflow upwards towards slats above, where air gets even warmer resulting in the increased velocity of going upwards. Thus the venetian blind system produces more intensive flow of warm air, which results in the increased air circulation in the are a around the venetian blinds. Greater airflow allows for more efficient use of solar heat for heating the room, reduces fogging of the window pane, and reduces possibility of mould forming on the window reveals. Such venetian blind system is easy to manufacture, one of the embodiments is easy to install in the existing venetian blind system.

Description

BACKGROUND OF THE INVENTION The present invention relates to fixed or variable positioning curtain shutters for buildings, more particularly horizontal blinds, which are capable not only of properly controlling the entry of sunlight and heat flux into the interior of a building, but also of increasing air flow. The air flow is formed and directed upwards by forming plates.

TECHNICAL LEVEL

One of the most important functions of building openings, through which the interior of the building has an optical connection with external (windows, glass doors, etc.) curtains (curtains, vertical or horizontal blinds, etc.) is to limit and control the flow of light to the premises. Perhaps the most important and intense irritant of a person indoors, which is promptly sought to be avoided by the use of vents, is glare. However, limiting sunlight also restricts the supply of solar heat to the premises, which increases the cost of space heating during the cold season. In the warm season, when the room needs cooling, the vents can reduce the cost of cooling the room by limiting the amount of solar heat. Efficient management of light energy and heat energy is a complex task. A variety of technical solutions are being developed and patented to achieve both of these goals (to properly manage both solar and thermal energy).

Blinds have two main modes of heat flow control purpose: a) Firstly, when there is excess heat in the room, the blinds should radiate as much solar heat backwards as possible, thus preventing excess solar heat from entering the room; b) second mode of heat flow control - in case of lack of heat in the room, the blinds must ensure maximum heat transfer to the room. In both cases, the blinds must also perform the light control function effectively.

Poor blinds consist of a large number of plates placed one above the other, connected to a rope system that holds the plates and can change the tilt angle of the plates relative to the glass plane of the window. The rope system shall consist of at least two vertical ropes with a large number of ropes attached to each of the vertical ropes. The ropes connecting the said vertical ropes are generally slightly longer than the width of the plates, the amount of said ropes between the two vertical ropes corresponding to the number of plates, and the plates are placed and secured thereon. The two vertical ropes and the large number of ropes connecting them, when perpendicular to the vertical ropes, resemble a ladder in its shape. In certain embodiments, a third, vertical, parallel to two vertical ropes may be inserted between the two vertical ropes, which pierces the plates, thereby securing the plates in the rope system. The ropes are made of a material (eg braided nylon, cotton threads, rubber, plastic, etc.), which provides a high degree of flexibility, the ability to wrap and shrink the system, while providing sufficient strength to sustain the blinds for a long time. Multiple rope systems (ladders) are used for one blind system, and they are fixed at intervals along the panels to ensure that the panels do not bend over their weight. The said rope system, with its fixed plates, connects to the mechanism at the top of the whole blind system, which facilitates and ensures the control of the blind system. One of the main elements of the blinds - plates. normal plate size: thickness: from tenths of a millimeter to a few centimeters; width: from several millimeters to several tens of centimeters; length: depending on the width of the window - from several centimeters to several meters. These sizes may, in exceptional cases, be different.

Patent US8307602B2, filed on May 2, 2012. Description of the Invention November 13, 2005 describes an invention in which a grille is attached to the outside of a window. The grille is made of a transparent material consisting of a segment of a cube that does not have two opposite planes, which are reinforced with each other in their planes. The grille is reminiscent of a honeycomb in its geometric structure. The thickness of the grille and the angle of inclination of the inner walls are shaped so that in the summer when the sun is high above the horizon, its direct rays do not penetrate the grille and do not enter the room. In winter, when the sun is low above the horizon, the sun's rays penetrate the grille and thus contribute to the space heating. There is no mention of active control of glare; the grille itself should limit visibility through the window, thus increasing discomfort; they cannot be folded or otherwise reduced in their window area (as in the case of blinds); for maximum efficiency, the size of the segments, the inclination angle of the internal partitions must be precisely matched to the geographical latitude.

Patent application US4593738A, published December 1986, is hereby incorporated by reference. Description of the system of blinds, consisting of two types (types), differing in the level of optical transparency. Different types of plates are mounted on top of each other, and in some cases the planes of the plates may be parallel to each other. The different types of plates are mounted so that they can be operated independently of each other. These types of blinds are designed to efficiently control the amount of light entering the room, but do not have the advantage of controlling the flow of thermal energy compared to conventional blinds. Another disadvantage of the present invention is described in US20110259529A1, which is published in 2011. October 27 It also provides blinds consisting of two systems of blinds, but in this case the panels are mounted side by side (one closer to the window plane and the other below); in certain embodiments, they may form "Z" shutters when the additional structural member is introduced. US5184659A (published February 2, 1993), US4880044A (published November 14, 1989), and many others, provide a solution for blinds that combine all panels into a single element reminiscent of a "W" shape forming a continuous window curtain, different from ordinary curtains only by folding. This solution is also not effective in heat flow management.

US4577619A (25.03.1986), VV02011023218A1 (03.03.2011) provide an effective system for controlling both heat and light with window blinds. The window blinds are located in a space that, depending on the position of the air valves in the window frame, can have direct interfaces with both the interior and exterior of the room. When the premises require heat, the valves are positioned so that the heat accumulated in the shutter panels enters the room and vice versa: when there is excess heat in the room, the heat accumulated in the panels is directed outwards. The system should be efficient but requires proper active control of the air valves. The system itself is quite complex to manufacture, installing it on existing windows requires changing all or substantially rebuilding the windows. The blind system itself must also be weatherproof.

US6192963B1 (27.02.2001) describes a positioning and control device for blinds. It also mentions the method of attaching the plates to the guiding cords: between the two main vertical cords, horizontal cords are used to place or secure the blinds, thus forming a reliable ladder control and positioning system in the form of a ladder. Said method of plate fastening is widespread but it has not been found that such method is used for fastening of heat flux forming plates.

US5918657A (06.07.1999) discloses a method of attaching blinds to panels without requiring holes in the panels. The plates shall be fixed to the holding cords by means of clamps, clamps or clamps securing the plate to either side of its plane and eyelets securing to the holding vertical cords. This method of fastening is also not used for fastening heat flux plates.

All of the documents submitted, in one way or another, seek to effectively control the solar heat and light entering the building, but they have the following problems:

the problem of active glare avoidance is not solved;

window blinds can obstruct the outside of the building, causing discomfort to those inside the building;

window blinds inefficiently solve the problem of solar heat flux entering the building interior;

efficient heat and light control system requires major changes in traditional window construction, complex control;

blinds are often used to prevent excess heat in the room, but rarely for space heating;

No solution has been found to intensify the flow of air at or near the opening of the building, depending on where the blinds are installed.

THE SUBSTANCE OF THE INVENTION

The purpose of the present invention is not only to efficiently control the penetration of solar heat and light into the interior of the building, but also to form and intensify the air flow in the space of the blinds. The conventional shutter system is enhanced by airflow and upward sliding plates. These forming plates may be formed as a separate structural element to be attached to the vertical rope holding the plates or formed within the plates themselves. In order to form the air flow, the forming plates are provided with openings through which the air flow flows, and when the holes are closed, the formed curved plane serves as an air flow guide. Both types of forming plates may be used together to form the air flow.

Blinds can be covered with heat-absorbing and radiation-enhancing material on one side and sun-reflecting material on the other.

Air jets direct the air to rise towards the plates above, where the air is heated further, which further increases its rate of rise. In this way, the blind system of the present invention produces a more intense flow of warm air than the conventional blind system, which results in increased air circulation in the space around the blinds. Higher airflow results in more efficient use of solar heat for room heating, reduces window glass dew, reduces the likelihood of mold on window openings. The blind system of the present invention is easy to manufacture, and one embodiment is easy to install on an existing (known in the art) blind system.

The present invention also provides structures that enable new ways of fastening forming plates as separate structural members.

BRIEF DESCRIPTION OF THE DRAWING FIGURES

PREFERRED {LIVING OPTIONS

The plate (1) (Fig. 1) (Fig. 2) of the present invention may be made of metal or other material with high thermal conductivity. In order to improve the heat flow control properties of said plate (1), one side / plane thereof is covered with a heat-absorbing layer - e.g. Titanium oxide particles (Tinox material) or the like; and the other side / plane of the plate is covered with a material that effectively reflects the heat of the sun. If the room temperature is to be increased, the heat-absorbing side of the plate is oriented towards the sun; if the room temperature is too high, the heat-reflecting side is oriented towards the sun.

Depending on the result to be achieved, said plate (1) may additionally be coated with materials having various functions: a material destroying viruses and bacteria (e.g., silver nanoparticles, etc.); an intensifying release of accumulated solar heat to the outside (eg silica or other); generating electricity (photovoltaic); capable of emitting light (fluorescent) or other functions in the dark.

Preferably, the cross-sectional shape of the plates (1) resembles a (slightly straightened "S") shape. This form is characterized by the most efficient absorption (absorption) of solar energy and is also sufficiently robust in design. In other embodiments, the cross-sectional shape may be different.

The angle of the plane of the panels (1) with the glass pane of the window can be freely changed, as in conventional blinds. As the heat-absorbing side of the plates (1) faces the sun, the temperature of the plates (1) begins to rise. The accumulated heat energy is released by the plates (1) to the surrounding air and the hot air starts to rise. in conventional blinds, most of the air enters the room, the rest of the air rising towards the plates (1) above, which heat the air even further. The present invention uses plates (2) for forming a rising air stream. These forming plates (2) direct the flow of air towards the plates (1) above to reduce the amount of air entering the room directly. The air thus rising is further heated by the plates (1) above, which increases the rate of air rise. As the rising air velocity increases, more air is sucked into the blinds system, increasing the efficiency of the entire blind system to absorb heat from the sun and heat the air in the heated room. J The system of air shutters passes through the lowest and lateral parts; hot air is removed from the blind system at the top of the system.

The heat flow forming plate (2) of the present invention is intended to direct the heated air of the plates (1) vertically upwardly towards the other plates (1) at the top, discharging as little heated air into the room as the entire surface of the blinds. Said forming plate (2) may be implemented as a separate structural element or formed as a component of the plates (1); it is also possible to use an individual forming plate (2) together with a component formed in the plates - a folded forming plate (3) (Fig. 3) (Fig. 4) - for the vertical air flow.

The forming plate (2), as a separate structural element, is similar in geometry to the plate (1). The transverse cross-sectional shape resembles "(" shape. In some embodiments, the lower portion of said shape may be slightly inclined in the opposite direction to the total deflection direction. The forming plate (2) may be made of optically transparent material (e.g., APET, PVC, or polycarbonate), in some embodiments, without distorting the natural image The forming plate (2) may be coated with the same, additional, separate materials as the plate (1), unlike the plates (1), the forming plates (2) can be covered with photochromic materials, which change the level of optical transparency depending on the amount of transmitted light flux.The forming plates (2) can be decorated with different colors, drawings.

The angle of the tiles of the forming plates (2) relative to the plane of the window is such that it is most effective in forming the vertical air flow, depending on the geographical latitude, and can be from 5 ° to 45 °.

In order to more clearly show the folded forming plates (3) in different embodiments, FIG. 10 illustrates several embodiments of a plurality (three) of folded forming plates (3) formed by holes (17) in the plates (1) themselves: a side view from the left and an axonometric view from the right.

Below we present and describe new constructions which enable new ways of fastening the forming plates (2) as separate structural elements:

1. a first new method of attachment allows the forming plates (2) to freely change the tilt angle without being able to raise or lower only the forming plates (2);

2. the second new way of fastening is without the possibility of changing the tilt angle freely and without the possibility of raising or lowering only the forming plates (2).

The present invention provides a first novel method and construction of fastening

The ability of the forming plates (2) as a separate structural member to freely change the inclination angle without the possibility of free lifting and lowering is ensured by the rope construction shown in FIG. 5. This structure, which resembles a ladder in its shape and which holds the plates (1), consists of horizontal ropes (5) and vertical ropes (8). The amount of said horizontal ropes (5) per vertical rope (6) corresponds to the number of forming plates (2). A further vertical rope (6) is attached to the other end of each of said attached horizontal ropes (5). Such a system forms another rope system, also reminiscent of a ladder shape. Thus, the three vertical ropes and a plurality of horizontal ropes connecting them form a system (7) resembling a double ladder with its long sides. The plates (1) are placed and fastened in the part of the rope system (7) closer to the window plane, the forming plates (2) are placed and fastened in the part of the rope system (7) further away from the window oriented inside the room. The above three vertical ropes connect their upper part to the control mechanism of the blinds. The double ladder-like system (7) of the three vertical ropes provides the function of tilting the plates (1) and forming plates (2) by raising and lowering the respective vertical ropes.

Second novel fastening method and construction of the present invention.

The fastening of the forming plates (2) as a separate structural element without the possibility to freely control the tilting angle of the forming plates (2) and without the possibility of lifting and lowering can be implemented in one of several ways. In this case, the forming plates (2) are fixed at an angle so as to best ensure the movement of the hot air towards the upper plates (1) and then towards the upper part of the blind system, which passes into the room. The forming plates (2) shall be fixed in such a way that their plane angle relative to the glass pane of the window can be varied, but no control and alteration of that angle is ensured. Most often, the forming plates (2) form a solid plane parallel to the glass pane of the window. Some of the aforementioned fastening methods are used to fasten (wrap, snap, fasten) to the vertical rope (8) of the rope system (4) (Fig. 6), which is further away from the plane of the window and is oriented inside the room. (s) or other method of attachment):

flexible loops (9) (Fig.6). These loops (9) are made of a material which ensures the functions and properties of the ropes; the eyelets (9) are sized such that the forming plates (2) can be easily inserted into them; the loop (9) is attached to the vertical rope (8) at one point, i.e. the forming plate (2) in the loop (9) is free to change the angle between the window plane and its apex coincides with the long axis of the forming plate (2). The other loop (9) is fixed at a distance from the existing vertical rope (8) close to the width of the forming plate (2). In this way, a plurality of flexible loops (9) corresponding to the amount of forming plates (2) are attached to the vertical rope (8).

pairs of flexible loops (11) (Fig.7). The loop pairs (11) of the loops (10) are made of a material ensuring the functions and properties of the ropes; fastened to the vertical rope system (4) with the rope (8) oriented inside the room. Each pair of flexible eyelets (10) is fastened close to each other. Another pair of flexible eyelets (11) is fastened from the preceding one at a distance close to the width of the forming plate (2), such that pairs of flexible eyelets (11) are attached along the entire vertical rope (8). Between the individual loops (10) of the loop pair (11) is formed a forming plate (2) with a hole whose distance from the edge of the forming plate (2) does not exceed the length of the loop (10) of the pair of loops (11); the diameter of the hole must be sufficient to pierce the rope (8). By placing the forming plate (2) between two pairs of loops (11), a vertical rope (12) of the same length is twisted through said hole in the forming plate (2) and through each of the loops (10) of the pair of loops. very close to the vertical rope (8) of the plate rope system. In this way, the loops (10) of the pair of loops (11) provide the height of the forming plate (2) and said vertical rope (12) ensures a stable position in the horizontal plane. This fastening method can also be implemented with only one loop (10) of a pair of loops (11).

hooks (13) (Fig.8). Hooks (13) are made of metal, plastic or other material with similar strength properties. The hook (13) is formed by folding an elongated (resembling cord) element of said material in half to form a double elongated element; a double elongated element is formed into a hook (13), the two free ends of which are fixed to a vertical rope, and a forming plate (2) is hung on the convexity of the hook itself. Alternatively, said double elongated member is secured in a vertical rope through its bending position, and the forming plate (2) is fastened to the two free ends forming the convexity of the hook. In the forming plate (2), holes are formed in which said hook (13) is inserted. The holes are formed close to the edge of the forming plate (2), whereby the forming plate (2) will be oriented towards the rope system, but not too close to the edge so as not to break.

brackets (14) (Fig.9). The holders (14) are made of plastic or other material of similar strength and flexibility. A suitable embodiment of the holder (14) may have a rectangular parallelepiped shape. The function of the bracket (14) is to fasten the vertical rope (8) holding the plates (1) at one end and to attach the forming plate (2) at the other end. Said bracket (14) can be made in such a way that the user of the blinds, who has no special skills or tools, can himself attach the forming plates (2) to the vertical rope (8). The end of the holder (14) for clamping the vertical rope (8) is formed as two separate ends and a space between them. The size of the gap shall be close to the thickness of the vertical rope (8); the vertical rope (8) must fit easily through the gap. When the vertical rope (8) is inserted into the gap, a technical means must be provided to close said gap tightly, thereby tightening the vertical rope (8) at said end of the bracket (14). The technical means for closing said gap may be an elongated structural member inserted into the openings (15) at both parallel ends, which are separated by said gap. In the holes (15) a locking element must be formed which prevents the elongated structural member from falling freely without the use of additional force. Said locking member can be various forms of widening / thickening in the elongated member and a similar shape of narrowing / thinning in the opening (15) into which the elongated member is placed.

The other end of the bracket is for mounting the forming plate (2). The end of the bracket (14) may have a horizontal hole (16) over the entire width of the bracket shape. The part enclosing said hole (16) is removed, thereby forming an opening having a cross-sectional shape resembling a "C" shape. a forming plate (2) is inserted into said opening, along its entire length, along its removed portion, the periphery (or only part thereof) thereof being fastened to said bracket having a thickening which secures the mounting plate (2) in the bracket (14).

Other embodiments of the construction of the element performing the function of the bracket (14) are possible.

All fasteners listed in variants a), b), c) and d) above are fastened to the vertical ropes (8) holding the plates (1). The forming plates (2) are raised and lowered together with the plates (1). The point of attachment must be such that the upper edge of the forming plate (2) is approximately midway between the points of attachment of the plates (1). If the upper edge of the forming plate (2) is close to the edge of the plate (1), this will severely limit the airflow movement, which may reduce the efficiency of the shutter system. The forming plates (2) are fixed to the vertical rope (8) at equal distances; all forming plates (2) mounted on a vertical rope (8) form an almost integral plane on the side of the room.

The air flow forming elements may be formed in the plates (1) themselves, in the form of a hole (17) or in a plurality of holes. The length of the orifice (17) along the plate (1) may vary. A hole (17) or a plurality of holes is formed over the entire length of the plate (1), if the method of fastening the plate (1) is required - except for the places where the plate (1) is attached to the rope system; also leaving the plane of the integral plate (1) at its ends to ensure the rigidity of the structure of the plate (1). Hole Width - The hole (17) is formed at the long edge of the plate (1), which is farther away from the glass pane of the window (with the plate (1) in a horizontal position), toward the room. In forming the aperture (17), one edge thereof is left integral with the plate (1), inseparable from the plate; at that edge, the portion of the plate which has been separated from the rest of the plate is curved to form a plane (3) (hereinafter referred to as a curved forming plate (3)) having an angle greater than about 25 ° with the plane of the remaining plate (1) . A possible way of forming the hole (17) is to leave three sides of the hole integral with the plate (1): one as in the case of one solid border and the other two adjacent to the said border. In this case, the opening, in its appearance, resembles a regular pocket for clothing (eg a shirt). Preferred embodiments are both when the said formed plane (3) is folded towards the top plates (1) or folded towards the plates (1) below. Through the formed hole (17), warmed air can enter the upper plates (1) and the folded forming plate (3) deflects the air flow upwards.

The present invention may be implemented using:

conventional shutters with forming plates (2) attached thereto;

plates with folded forming plates (3);

plates (1) with folded forming plates (3) together with forming plates (2).

Plates (1) with folded forming plates (3); and, but not necessarily, forming plates (2); a rope system (4) (7) holding all the plates; the control mechanism, which is connected by the system of supporting ropes (4) (7), all of which together with the additional elements form a single system of blinds which not only efficiently controls the penetration of sunlight and heat into the room, but also intensifies air movement its where this system is built.

The above-mentioned system of blinds is mounted on the inside of the room, in the openings (or cavities) (or covering the openings, without entering the inside of the openings) having a direct optical connection with the external environment (eg window opening, glass door opening, etc.). Maximum room heating efficiency is achieved by installing the blind system in the south-facing openings. In the openings facing north, the heat-capturing and radiating blinds have the lowest efficiency. Blinds can usually be fixed to existing windows, doors (or other) structures without changing anything.

The main difference between these blinds and their forming panels is that they are more efficient in absorbing solar energy and forming and controlling the airflow, providing more intense airflow in the blinds space.

Higher airflow than conventional blinds results in higher air circulation at the wall opening, which can reduce the likelihood of mold and reduce glass dew.
