Definitions

  • the invention relates to fixed or adjustable coverings of openings in buildings, specifically horizontal Venetian blinds capable of not only proper control of sunlight and heat entry into the building, but also of forming increased airflow. Airflow is formed and directed upwards by means of forming slats.
  • coverings curtains, vertical or horizontal blinds, etc.
  • coverings which provide visual contact of the internal premises with the outside (windows, glass doors, etc.)
  • glare which is promptly tried to avoid by using coverings of openings.
  • reduction of sunlight also reduces entry of solar heat into the room, leading to the increased heating costs during the cold season.
  • coverings of openings may reduce cooling costs by restricting entry of solar heat into the premises.
  • Efficient management of luminous energy and thermal energy is a complex task. Seeking achievement of both of these goals (to properly manage both sunlight energy and thermal energy), various technical solutions are being created and patented.
  • Venetian blinds serve to achieve two main goals of heat flow management: a) the first one: when there is excess of heat in the room, Venetian blinds have to reflect as much solar heat back to the outside as possible thus preventing excess solar heat from entering the room; b) the second one: when there is a lack of heat in the room, Venetian blinds must ensure the maximum ingress of solar heat into the room. In both cases, Venetian blinds must also efficiently perform the function of management of flow of light.
  • Conventional Venetian blinds consist of a plurality of slats placed one above another and interconnected by a cord system that holds the slats and can change the slate tilt angle with respect to window glass plane.
  • the cord system consists of at least two vertical cords with a multitude of cords attached to both vertical cords.
  • the cords connecting the said vertical cords are usually slightly longer than the slat width, the quantity of the said cords between the two vertical cords corresponds to the quantity of slats; the slats are mounted and attached to them.
  • the two vertical cords and a multitude of interconnecting cords perpendicular to the vertical cords resemble a ladder by their layout.
  • the third vertical cord can be placed in parallel between the two vertical cords passing through the slats to ensure stability of the slats in the cord system.
  • the cords are made of a material (such as woven nylon, cotton threads, rubber, plastic, etc.) that provides great flexibility of the said system, possibility to roll up and retract, simultaneously providing sufficient strength to hold slats for a long time.
  • a single Venetian blind system incorporates several cord systems (ladders); these are attached along the slats at certain intervals to ensure that the slats do not sag under their own weight.
  • the said cord system with the attached slats is connected to the mechanism that is located at the top of the entire Venetian blind system and that facilitates and ensures the control of the Venetian blind system.
  • One of the main components of Venetian blinds is slats. Standard sizing of slats is as follows: thickness ranges from decimal fractions of a millimetre to several centimetres; width ranges from several millimetres to dozens of centimetres; length ranges (depending on window width) from several centimetres to several metres. These dimensions may be different in exceptional cases.
  • the patent US8307602B2 published on 13 November 2012, describes an invention where grate is mounted exterior to a window.
  • the grate is made of transparent material and consist of segments shaped as a cube without two opposite planes; these segments are attached to each other at the surfaces of their planes.
  • the geometrical structure of the grate resembles a honeycomb.
  • the thickness of the grate and tilt angle of internal walls are selected so that in summer, when the sun is high above the horizon, the direct sunlight cannot pass the grate and enter the room. In winter, when the sun is not high above the horizon, sunlight passes the grate and thereby can contribute to heating the room.
  • Patent application US4593738A published on 10 June 1986, describes a Venetian blind system comprised of the slats of two types that differ in their optical transparency. Slats of different types are placed one above another, planes of slats in certain cases can be parallel and in contact with each other. Slats of different types are mounted so that they can be controlled independently. Venetian blinds of this type are intended for efficient control of light entering the room but they have no advantages in control of thermal energy flow compared to traditional Venetian blinds. The same shortcoming is inherent to another invention described in document US201 10259529A1 , published on 27 October 201 1 .
  • Venetian blinds comprised of two systems of slats, but in this case the slats are attached one next to another (some closer to the window pane and some further) and in certain implementation cases they can make Z-shaped blinds provided that additional structural component is introduced.
  • Documents US5184659A date published: 9 February 1993
  • US4880044A date published: 14 November 1989
  • many others present a Venetian blind solution where all slats are connected into a single element resembling W- shape comprising the entire window covering that differs from the conventional curtains only in the method of folding away. This solution also does not offer efficient heat flow management.
  • Patent US6192963B1 (27 February 2001 ) describes a device for positioning and control of slats of Venetian blinds. It also mentions the method for attachment of slats to slat-controlling cords: horizontal cords are placed between two main vertical cords and Venetian blind slats are put on or attached to these cords to obtain ladder-shaped reliable system for control and positioning of slats. The said method for attachment of slats is very popular, however we could not find any application of this method for mounting of heat flow-forming slats.
  • US5918657A (06 July 1999) provides a method for attachment of slats, which does not require holes in slats. Slats are attached to holding cords with clips or clamps, which grip and hold the slat on its both flat sides, and loops that are attached to vertical holding cords. This method for attachment is also not used for attachment of heat flow-forming slats.
  • window coverings may encumber seeing outside the building, leading to discomfort for people inside;
  • window coverings are not efficient in resolving the problem of solar heat ingress into the building
  • Venetian blinds are often used to prevent excess heat in the room, but rarely for heating the room;
  • This invention is aimed not only at efficient control of solar heat and light ingress into the building, but also at forming and intensifying airflow passing the plane of Venetian blinds.
  • Conventional Venetian blind system is improved with airflow forming and upwardly directing slats.
  • These 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.
  • openings for air to go upwards are made in the forming slats and the bent plane, which is obtained when making openings, serves as an airflow guide. Forming slats of both types can be used in combination to form airflow.
  • Slats of Venetian blinds 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.
  • Venetian blind system equipped with this invention produces more intensive flow of warm air compared to conventional Venetian blind system, which results in increased air circulation in the area around the Venetian blinds. Greater airflow allows for more efficient use of solar heat for heating the room, reduces fogging of window pane, and reduces possibility of mould forming on the window reveals.
  • the Venetian blind system equipped with this invention is easy to manufacture, one of the implementation options is easy to install in the existing Venetian blind system.
  • This invention also presents designs that enable application of new methods for attachment of forming slats as separate structural elements.
  • This invention utilizes slats (or their forms) of different purposes, which serve at least two major functions: a) management of flow of light, as usual; b) airflow forming and management, which is novel.
  • both functions can be performed by either a single slat, shaped in a special way, or a system of two different slats.
  • slat (1 ) refers to a slat used in conventional Venetian blinds and applied in related art and serving to manage flow of light; another term is forming slat (2) that denotes a Venetian blind system component as an individual structural element that forms and controls airflow (this is novel).

Abstract

L'invention concerne un système de store vénitien classique amélioré grâce à des lattes de formation formant un flux d'air dirigées vers le haut. Les lattes de formation peuvent être mises en œuvre sous la forme d'un élément structural distinct fixé au cordon vertical maintenant les lattes ou peuvent être formées à l'intérieur même des lattes. En vue de former des éléments structuraux formant un flux d'air, des ouvertures sont ménagées dans les lattes pour permettre à l'air d'aller vers le haut et le plan de courbure, qui est obtenu lors du ménagement des ouvertures, servant de guide pour un flux d'air. Des lattes de formation de deux types peuvent être utilisées en combinaison pour former un flux d'air. Des lattes de store vénitien présentant un contact optique direct avec le soleil peuvent être recouvertes d'un matériau qui augmente l'absorption et la libération de chaleur sur un côté et d'un matériau qui réfléchit la chaleur solaire sur l'autre. Les lattes de formation dirigent un flux d'air vers le haut en direction des lattes au-dessus, où l'air se réchauffe encore en raison de l'augmentation de la vitesse de montée. Ainsi, le système de store vénitien produit un flux d'air chaud plus intensif, ce qui permet d'obtenir une circulation d'air accrue dans la zone autour du store vénitien. Un flux d'air supérieur permet une utilisation plus efficace de la chaleur solaire pour chauffer la pièce, réduit la formation de buée sur la vitre et réduit le risque de formation de moisissure sur les encadrements de fenêtre. Un tel système de store vénitien est facile à fabriquer, et l'un des modes de réalisation de la présente invention est facile à installer dans un système de store vénitien existant.
