Lamella sunscreen blinds
(57) Abstract:Lamella sunscreen blinds to improve reliability, design and facilitation includes a housing made of variable length, variable depending on the overall decorative type louvers, decorative inserts installed on the lower end of the housing, in the upper part of the body has a hole for hanging slats, and all the inserts are placed in the same height of the cross-section of the longitudinal groove of the housing formed by the longitudinal side grooves. 4 C.p. f-crystals, 3 ill. The invention relates to a device sunscreen blinds, especially vertical type with elements of decorations, giving them the appearance of window curtains.Known lamella for sun blinds, containing longitudinal concave and convex elements of the pair, with concave elements have made of rubber bands elastic diaphragm, fixed on them longitudinal edges (ed.mon. USSR N 563474, CL E 06 In 9/386, 1977).Factor hindering the achievement of the required technical result is the lack of universality known slats, because it is only for specialista also lamella for sun blinds stable form, consisting of a double layer of aluminum tape, covered on one side with plastic and laminated rollers to complete the section with covered inside, with hollow section has at least one point of contact, in which two layers of aluminum tape tightly interconnected (RF patent N 2039866, CL E 06 In 9/15, 1991).The disadvantage of this known lamella is the complexity of its design and technological implementation.The closest technical solution of the invention is the lamella sun blinds US patent N 5394925, CL E 06 In 9/00, 1995. It contains elongated rectangular case with front and back surfaces, and the longitudinal edges along which made holders, each holder having two or more longitudinal troughs that hold the insert.The obstacles to achieve the desired technical result of known construction slats sunscreen blinds, is its relative complexity in cross-section (thickness), because all the inserts are placed in separate trenches, each subsequent of which is the "floor" above the previous one. This causes considerable thickness lamas who do. There are no fasteners inserts to the body, and they are held only by friction forces. However, different temperature coefficients of contraction and expansion of the material of the inserts, and hull insert constantly fall out of the grooves of the housing. This known plate is rigid throughout its length, which creates noise at impact slats apart from drafts. In addition, the body of the slats has a blank portion of the longitudinal grooves on the front surface of the filled shorter inserts, which reduces the effect of aesthetic perception slats and blinds in General.The objective of the invention is to simplify design, increase its reliability, efficiency and improved aesthetic appearance.In addition, the goal to offer such a design of the slats, so that the blinds were detained only direct sunlight, creating room prosvetlio-dim pleasant comfortable surroundings.The result is due to the fact that the lamella sunscreen blinds includes an elongated body with a convex face and a concave rear surface with a longitudinal side edges, which are longitudinal troughs attached to them from the front side Scavolini, variable depending on the overall decorative type louvers, decorative transverse insert installed on the lower end of the housing and attached to the upper outer box. In the upper part of the body has a hole for hanging slats to the eaves and has fastening element fastening the insert to the body. All inserts slats placed in one, the height of the cross section, the groove of the housing formed by the left and right longitudinal side grooves. With one insert, which is attached to the casing, is a principal, she has a full length blinds and can be performed, for example, of a flexible translucent Mylar or polyester fabric in various colors. The coefficient of internal transmittance of sunlight this fabric is *= 0,2-0,6. In the lower part of the main insert secured cargo. The goods of all slat blinds are interconnected with a metal or plastic chain. The enclosure can be made of a hard durable material such as plastic. Housing length Ltomay vary in the range of LlLtoLWwhere Ll- length prikarniznoe part of slats required to perform holes for hanging Lam is e insert may be arcuate or rectangular shape and run, for example, the color of the metal foil or plastic. Longitudinal profiles on the housing can be made of the teams, and the front part is made transparent.In Fig. 1 shows a General view of the slats of Fig. 2 - section a-a in Fig.1; Fig. 3 is a left side view and cross section b-b In Fig.1.Lamella contains sunscreen blinds rigid casing 1, having a convex face and a concave rear surface. Housing length Ltois a variable value that varies depending on the decorative type louvers in the range of Ll- size prikarniznoe part of slats required to perform holes for hanging slats and installation of the fastening element to the LW- full length shutters. From the front convex side of the body is made of two (left and right longitudinal side edges formed by the bent ends of the housing slats, to which is attached a transparent cover 2, forming the left and right longitudinal trough 3. Both gutters together represent one (height in cross-section) through the entire length of the groove on the front surface of the housing 1 of the slats. The housing is usually made of a durable material, for example, of hard plastic. In the specified slot of the housing 1 is placed nei Ltois a through hole 7 for its hanging on the ledge, and the fastening element 8, for example, as brass or plastic rivets. The main box has a full length blinds LWand in its lower part fixed load 9. It can be made of translucent flexible Mylar or polyester fabric in various colors. When the transmittance of solar radiation such tissue can be*= 0,2-0,6. Such physical parameters fabrics provide detention to direct sunlight, creating room prosvetlio-dim a comfortable environment (see Physical quantities. The Handbook. Edited Grigorieva, I. S. , Malikova E. H. - M.: Energoatomizdat, 1991, S. 776-786). The load 9 is provided with side lugs 10, through which all the slats one louvers are interconnected, for example, decorative plastic or metal chains. Decorative cross the insert 6 is installed at the lower end of the housing 1 from its front surface and attached to the top box 5, for example, with adhesive. In one case can be placed a few of these decorative inserts. They can be made of metal color foil, for example brass, is edlagaemoe lamella sunscreen blinds are collected as follows.Blank is laminated on profilebase the machine housing 1 lamella is cut into longitudinal segments of variable size so that the assembled blinds the lower ends of the casing with its decorative cross inlays formed a certain decorative geometric pattern on the General background of the canvas blinds: for example, the arch, portal, single or double - sided arc, etc., Further from the front convex surface of the bent to the side ends of the housing 1 are mounted transparent cover 3 by bonding or thermopile. In formed on the surface of the body left and right gutters groove set the main 4 and upper 5 inserts that are bonded to the housing 1 of the fastening element 8. Then installed in the same groove decorative cross the insert 6, which is attached to the upper box 5 glue. On the lower part of the main insert 4 set the load 9.Collected slats in a certain sequence depending on the appearance of the blinds (arch, portal, etc) through the hole 7 suspended from the eaves of the blinds. All goods of one slat blinds connected with two sides of metal or plastic chains that hold all the slats of the blinds in one Plessi the unity of form and aesthetically pleasing decorative appearance.Proposed according to the invention the team lamella is simple in construction, compact, reliable, easy to use and has a good aesthetically pleasing decorative appearance. Blinds of such slats are detained only direct sunlight, giving the room a pleasant and comfortable environment. 1.
