Description

The field of technology to which the PM belongs

The utility model relates to the field of devices used to control the intensity, color and polarization of light coming from an independent source, is designed to control the intensity and color of the light flux and can be used in building window structures.

State of the art

Known vertical lamella, composed of separate segments of different materials, fastened together by means of a stitched material or glue or heat treatment. A composite lamella made of bonded segments of various lengths, compositions, textures and colors allows you to vary the illumination of the room by placing segments of materials of low light transmission and darker tones in the upper parts of the lamellas, or in those places along their length where it is necessary to muffle the luminous flux, increasing the protective shutter functions. Varying the lengths of the segments of the slats relative to the lengths of the segments of adjacent slats and the configuration of their pairing allows you to get any patterned design of the blinds [PM No. 6016, MKI E06B 9/36, E06B 9/386, publ. February 16, 1998]. However, the disadvantage of the known lamella is that the technology of its manufacture in mass production does not ensure the closeness of the seam zones of the lamella and the strict straightness of the lamella along the vertical as a result of the sequential connection of the components of the lamella with an overlap and their location in different vertical planes, which reduces the aesthetic quality of the blinds.

Also known is a vertical lamella of sun blinds, containing a tape formed from segments of tape materials with different colors and textures and a decorative element installed in the connection zone of the segments. Decorative elements are made in the form of two strips, which are installed by double-sided overlay on the tape segments in the area of their connection and are firmly connected to each pair of segments by stitching or gluing [PM No. 65936, E06B 9/36, dated 27.08.2007]. Decorative elements that hide the zone of connection of tape sections, strengthen it and place the lamellas in one plane, aligning the lamella along the length.

to strengthen the zone of connection of the segments of the tape material and thereby align the lamella in the plane and along the length, two-sided overlay of decorative elements is used on the junction line of the composite tape segments with the obligatory joint fastening of each of the elements with their joined ends. Such a design of a composite lamella does not ensure the manufacturability of its manufacture, especially in mass production, since when decorative elements are fixed together, the measured lengths of the tapes relative to the junction line can almost always be shifted, which ultimately worsens the quality of the product.

The closest in purpose and technical essence is the device of a multilayer slat sun blinds, formed from tape materials with different colors and a decorative element, which is fixed in the area of their connection. The decorative element is made in the form of an overlay with a wall and grooves and an artistic insert. The edges of the tape and the artistic insert are tucked into the grooves of the lining, the segments of the tape material are overlapped (Pat RF 108 082, IPC E06B 9/262, published on September 10, 2011 Bull. No. 25).

A disadvantage of the well-known vertical lamella device is the use of toxic dyes and pigments to obtain different colors of tape materials, the fading of dyes in the sun and the inability to change the color of the lamellas and transparency by moving or rotating them relative to the direction of the light flux.

The technical problem to be solved by the device is to obtain sun-protection and decorative functions of the blinds slats without the use of colored toxic dyes in their production.

The essence of the proposal

The multilayer lamella, formed from tape materials with different colors, according to the proposal, is made of transparent thermoplastic tapes and two film polarizers, between which thermoplastic tapes are placed. Polypropylene, polyethylene, polystyrene, polyvinyl chloride are used as thermoplastics for transparent tapes.

Example 1

A multilayer lamella formed from tape materials with different colors (Fig. 1) is made of 3 layers of a heat-shrinkable polyvinyl chloride (PVC) film 75 microns thick and 10 cm wide located between film polarizers of the NPF F1205DU brand (Japan) in the form of tapes 10 wide see When the lamellas overlap up to 50% of the width of the lamellas (Fig. 2), 60% of the light flux of a monochrome brown color passes through the window. The color of the light flow through the lamellas of 3 layers and the color of the flow through the area of their overlap, in which there are 6 layers of polyvinyl chloride film, visually coincide. Quantitatively, the transparency of the lamellas is determined by the X-Ritei1Pro brand spectrophotometer using the spotread command line module from ArgyllCMS version 2.3.0 according to the parameter L - lightness. Lightness of 3 layers - 60, Lightness of 6 layers - 85, which corresponds to the average transmittance of blinds in the closed state.

Example 2

A multilayer lamella according to example 1, but from 4 layers of a low-density polyethylene (PE) film 75 μm thick and 10 cm wide located between film polarizers of the NPF F1205DU brand (Japan) in the form of tapes 10 cm wide. When the lamellas overlap up to 50% width of the slats, 40% of the green monochrome luminous flux passes through the window, which corresponds to the low transmittance of the blinds in the closed state.

Example 3

Multilayer lamella according to example 1, but vertical lamellas from 5 layers of polystyrene (PS) film form an overlap of 1% when closed. Green light passes through the window through the lamellas of 5 layers. The lightness of 5 layers is 75. A section of lamellas from 10 layers combined with an overlap of 1% of the width passes pink light. Lightness of 10 layers - 70. The lamella provides a decorative effect of multicolor and high transparency.

Example 4

Multilayer lamella according to example 1, but for decorative roller blinds (Fig. 3), consists of 2, 3 or 4 layers (15 - wound multilayer lamella, 16 - transparent tape material polarizing light, 17 - two layers transparent tape material polarizing light and biaxially oriented polypropylene film) (Fig. 3). multi-colored lighting in the room. The number of layers that transmit light and the color of the light flux depends on the relative position of the lamellas. In the open version, yellow light passes through 2 layers of tape materials into the room, in the closed position, blue light passes through 4 layers into the room. In intermediate positions, with the formation of a partial overlap (overlap) of the lamellas, a decorative effect of 3 colors takes place. Lightness will also vary.
