Description

The invention relates to the field of identification tools and decorative elements, reflecting in a wide range of angles of reflectors in any weather conditions, and can be used in license plates for cars and motor vehicles, road signs, badges, signs, including street signs, houses and other decorative elements that are equally well visible both in the light and in the dark.

The problem of obtaining simple in design, cheap and effective index signs, including the capabilities of modern design, including three-dimensional ones, containing various decorative elements, is quite acute. This is due to the fact that the signs used in the world are either completely simplified and represent an opaque stencil glued to the lamp, or too expensive when index signs are made of metal. In addition, existing signs and signs cannot be identified in the dark and therefore must be highlighted.

A known license plate for motor vehicles containing a light panel with convex dark digital and alphabetic indices made perforated, the panel is fixed to the base in the form of a box with a depth of at least two diameters of the perforation holes, and lamps are installed at the side walls of the box [1].

The well-known license plate is structurally complex and difficult to clean, since the inner surfaces in the box are difficult to access.

There is also an index sign containing a panel mounted on a transparent material with indexes made on its surface and an opaque layer not covering the indices and a metal layer made of a material with highly reflective properties, while the back surface of the panel has recesses, unlike the prototype, an additional opaque dark layer and is applied to the indices, the recesses are made in the form of cavities located between the separated boards with pointed structures, the vertices of which are directed They are removed from the back surface, the opaque layer is made light and deposited on the boards between the pointed structures, while the metal layer is applied on the side surface of the pointed structures [2].

The known technical solution is quite difficult to manufacture, because it consists of many parts. In addition, the non-covering index layer is reflective, which emphasizes the index mark at close range, but from a far distance the indices become poorly distinguishable. Moreover, the indicated index mark is mainly aimed at the use of automobile license plates and it is rather difficult to decorate it well.

As a prototype, an index sign was selected containing a panel made of a transparent polymeric material mounted on the base with indexes and recesses made on its rear surface, a film transparent coating deposited on the recesses of the rear surface of the panel, an opaque layer deposited on the film coating, a transparent non-metallic layer deposited on an opaque layer, and a lighting device installed with the ability to illuminate the film coating through a translucent metal layer, while in the opaque windows corresponding to indices on the back surface of the panel [3] are formed in the layer.

However, the known technical solution is technologically difficult to manufacture, requires an additional transparent film coating and the application of three layers on top of each other on the back surface of the panel, and its retroreflective properties and contrast are not high enough due to the presence of only a translucent non-metallic layer that functions through several coating layers. The absence of dark and light opaque areas contrasting with each other in the index sign reduces the contrast when distinguishing indices and, as a result, the distinguishability of the sign indices is reduced.

The problem solved by the present invention is to simplify the design of the index sign, while maintaining the wide possibilities of its decorative capabilities and good distinguishability both in the dark and in the light.

The problem is solved in that the known index sign containing a panel on the basis of a transparent polymer material with indexes made on its surface and an opaque layer, according to the invention, is extruded onto the panel and filled with self-hardening ballast material.

The problem is also solved by the fact that the bottom and / or side walls of the extruded index mark are covered with a decorative opaque mask. The problem is also solved by the fact that the decorative mask contains light guide holes, and the self-hardening ballast material is made transparent.

The problem is also solved by the fact that in the ballast self-hardening material holes are made to accommodate light sources or light sources are placed.

The problem is also solved by the fact that the index panel is equipped with a self-adhesive layer.

The problem is solved in that the mask on the front side is covered with a retroreflective layer.

The problem is solved in that the side walls of the extruded index mark are stepped and / or conical.

The invention is illustrated by drawings.

In FIG. 1 shows a general view of the index mark; FIG. 2-5 - various versions of the profile of the sign (section AA of FIG. 1), in FIG. 6 - index mask with various light guide holes.

The index sign consists of base 1, on which one or more indices are mounted. The base serves as a technological substrate for the complete manufacture of the sign, however, subsequently, the base 1 can be used for fastening the index sign. On the base there is a panel 2 made of a thermoplastic deformable material, for example polyethylene terephthalate (PTFE), in which, by known methods, for example, by vacuum extrusion into a mold or by thermopressing, profiles of the required indices 3 are made. On panel 2, one or more indices 3 can be made 3. At the bottom and / or the side walls of index 3 lay a mask 4, which is pre-made by known methods, for example by stamping, plotter cutting. If necessary, the mask may have a retroreflective coating and / or light-conducting holes on the front side 5. After laying the masks 4, the cavity in the panel is filled with self-hardening polymer 6. If necessary, holes 7 for lighting devices 8 are left in it or even when using cold light sources they inserted into a self-hardening polymer in a liquid state. After curing, the panel or panels 3 are fixed by known methods on the base 1, on which a self-adhesive film (not shown) can be previously fixed. After the installation of panels 3 on the basis of 1 is completed, the entire assembly can be filled with a self-hardening compound 9 and, after hardening, the index sign is ready for use.

To provide different options for decorative design of the index mark, the side surfaces of the panel can be made vertical (Fig. 2), conical (Fig. 3), stepped (Fig. 4). In this case, the mask can be located at the bottom of the recess, on the side surface of the recess, or at intermediate sites when the recess is made stepwise. Together with the use of a transparent self-hardening polymer 6 and illumination of the sign from the inside using lighting devices 8, for example LEDs, various decorative effects can be achieved. You can enhance the decorative effect by making holes in masks of various shapes. When using index signs as road signs, the face of the mask is covered with retroreflective material.

It is possible to use the indicated index signs in the venues of various events: exhibitions, shows, sports, both in permanent premises and in temporary venues. At the same time, the signs are light in weight, cheap to manufacture and install, easy to operate, very different in daylight and in the dark, very decorative. The signs are resistant to physical and chemical influences and have a structural rigidity due to the use of a composition of thin-film decorative and structural materials and a filler. Another area of application of the new index signs may be the manufacture of plates with the names of streets and house numbers. There are practically no restrictions on the size of index signs, and because of their volumetric performance, they will be perfectly visible from any point at any time of the day.
