A smooth optical transition is thus obtained, making it possible to decipher the indicator symbols (18) even in oblique view, and on the other hand making it possible to eliminate the disturbing effect of electric elements visible towards or at the periphery of the display (12) or similar.

Description

EDGE FOR VISUALIZATION WINDOWS IN HOUSINGS

  The invention relates to a window border, for transparent viewing windows or in the form of cut-outs in housings where there is arranged, near the window, a display visible through the window, an indicator, a light device or the like. In the case of programmers, measuring instruments or other display systems, in which a display, for example with digital display or another indicating device must be seen by the user, transparent viewing windows are already known. provided in the corresponding boxes, under which the display or other indicating device are placed The window can be made either of glass or of transparent synthetic material and be placed in a box itself transparent or translucent, or else be produced under the form of a cutout in the housing In the latter case, the display can also be incorporated

in the cutout.

  Displays and other indicating devices are electrical and / or electronic components, at the periphery of which electrical connections, degassing areas by Getter, suspensions of heating wires or the like are often visible. A display is composed for example essentially of a glass body, at the periphery of which such elements are visible through the glass body This produces a discomfort effect on the user, diverts his attention from the display itself, and

  detracts from the aesthetics of the device as a whole.

  The object of the present invention is to create a border for a viewing window of the type mentioned above, through which the indicator symbols of the corresponding display or of another indicating device remain clearly visible and easily decipherable in the window, while in

  concealing the disturbing elements of the periphery.

  According to the invention, this problem is solved with the arrangement, on the periphery of the window, of a multitude of opaque or translucent patterns, the size and / or the density of the patterns decreasing towards the middle of the window. Such a border for a viewing window has the advantage that the degree of overlap increases continuously from the middle of the window, where the indicator symbols are located, up to the edge of the window, so that a transition is obtained smooth optical, that the indicator symbols are still clearly decipherable even in oblique view, and that on the other hand the disturbing effect of the electrical elements visible towards and in the periphery of the display or the like is eliminated Because the patterns have a size and / or a density which decreases towards the interior, these can be arranged as close to the symbols or the indicating elements, or even reach them, these remaining

  still easily readable or decipherable.

  In the simplest case, the patterns can be applied directly on or in the wall of the case, for example inside or outside of a transparent window They can also be placed directly on the glass body of the In addition, it is possible to arrange the patterns on a transparent film, which can advantageously be an adhesive film bonded to the external or internal face of the

  housing in the window area.

  In the simplest case, the patterns are overprinted, but they

  can also be applied by other coating methods.

  In order to ensure a smooth optical transition, the patterns can extend outwards beyond the edge of the window. Thus, the outline of the window disappears notably, so that the symbols or indicator elements are particularly highlighted. relief thanks to transitions

smooth optics.

  The patterns have essentially a point shape, but the most diverse geometric shapes are possible, such as circular surfaces, polygons, ovals, rings or the like. These patterns are advantageously arranged in a grid, the rows and / or columns respectively adjacent also being able to be offset from each other

(staggered arrangement).

  Advantageously, the density of the patterns increases towards the outside until it reaches approximately 100%, so as to improve the continuous optical transition towards the generally opaque casing. In addition, the

  patterns are advantageously the same color as the case.

  An embodiment of the invention is shown in the drawing

  and explained in more detail in the following description.

  Figure l is a front view of a display housing comprising application of the invention; Figure 2 is a simplified section of the device shown in the

figure 1.

  The example of embodiment shown comprises a box 10 of a programmer, with a viewing window Il rectangular and transparent, which can be integrated into or fixed to the box. In the box is arranged under window II an electronic display 12 with digital display. , whose electrical connections 13 are connected to a printed circuit board As shown in the figure, the connections 13 are partly visible in the periphery of the display 12, and this through the transparent glass body of the display 12 In addition , may be visible for example a suspension of heating wires not shown, a degassing range by Getter or the like For the adjustment and control of the display 12 and of corresponding circuit elements, connected but not shown, of the control members 15 are arranged on the housing 10; these are however not described in more detail, since they are not the subject of the present invention. Above the window A transparent adhesive film 16 larger than this is stuck on the housing 10. On the latter, dot-shaped patterns 17 are superimposed, the size of which decreases by outside towards the inside of the window, so that the density of the patterns also decreases from outside towards inside In the most interior area, in which the digital display 18 of the display 12 is visible , no pattern 17 is provided As shown in particular in FIG. 2, the lateral connections of the display 12 are optically covered by the patterns 17, so that they are barely identifiable even when viewed from above and obliquely Since the density of the patterns 17 is the lowest in the area of the digital display 18, the display is

  still easily decipherable if you look at it obliquely.

  The patterns 17 can also be placed as close as possible to the display 18 in the case where their density is very low, while their density, on the other hand, approaches 100% towards the outside, so that '' a continuous optical transition to the housing is obtained, and this

  particularly when the color of the patterns 17 corresponds to that of the housing 10.

  The patterns 17 can be arranged according to a fixed grid or be offset from one another, as shown in the area where their density

is weak.

  Instead of the patterns 17 of round shape shown, practically

  any other geometric shape can be chosen.

  The adhesive film 16 can be glued not only on the outside of the case 10, but naturally also on the inside or on the display 12. In the case where, instead of a transparent window 11, only a window in the form of a cutout, the adhesive film 16 will be

  reinforced and will cover this cutout.

  As a variant, it is also possible to overprint the patterns 17 directly on the outside or inside of the case, or on the display 12, or to apply them in another way In addition, to modify the density of the patterns , their surface and / or their number can be reduced towards

outside to inside.
