Summary of the invention

The purpose of this invention is to provide a kind of plastic perspective sheet, when adopting this plastic perspective sheet as the dioptric lens in the three-dimensional impression picture, rocking of three-dimensional impression feels little, and especially relief the rocking of image feels less.

The present invention is achieved in that

1, a kind of plastic perspective sheet comprises transparent plastic tab 1, and a surface of thin slice 1 is that plane 11 and another surface have the intensive long and narrow convex face 12 that is arranged side by side, and the junction of each convex face 12 forms straight line 13, and its characteristics are:

(1) the camber h1 of described convex face 12 is, 1mm 〉=h1 〉=0.05mm;

(2) thickness h 2 of thin slice 1 is 10mm 〉=h2 〉=1.5mm;

(3) described arc bottom width B is 5mm 〉=B 〉=0.01mm;

(4) arc of described convex face 12 is oval parts, and, E＞F.

2, on the basis of above-mentioned article one technical scheme, characteristics of the present invention are: with plastic perspective sheet of the present invention as the dioptric lens that covers pattern C or pattern D or other pattern front surface of the same type, the plane 11 of this plastic perspective sheet is adjacent with the front surface of pattern C or pattern D or other pattern of the same type, for example, with reference to Fig. 1 and Fig. 5, when the plane 11 of this plastic perspective sheet is pressed close to mutually with the flat board with pattern D or is printed on pattern D on the plane 11, vertical mark of Fig. 1 and vertical mark of Fig. 5 are in correspondence with each other, form picture with three-dimensional impression (especially three-dimensional impression), again for example, with reference to Fig. 1 and Fig. 4, in like manner form picture with three-dimensional impression, described picture with three-dimensional impression can be used as cosmetic sheet, applicable to wall fitting (sliceable is large-area wall or local the decoration).

When people were watching the picture of the three-dimensional impression of the present invention of hanging on the wall and moving, little (for example, rocking of the three-dimensional impression of image feels little) felt in rocking of described three-dimensional impression.Usually, when watching picture on the wall, people move, so the sensation of rocking of the three-dimensional impression of image is a kind of advantage for a short time through regular meeting.

Embodiment

Describe the details of the concrete plastic perspective sheet that proposes according to the present invention in detail below in conjunction with accompanying drawing.

With reference to Fig. 2 and Fig. 1 and Fig. 3, when making plastic perspective sheet of the present invention by prior art, get the arc of oval a part of camber line, E＞F as shown in Figure 6 and Figure 7 described convex face 12; And the camber h1 of described convex face 12 is 1mm 〉=h1＞0.05mm; The thickness h 2 of thin slice 1 is 10mm 〉=h2 〉=1.5mm; Described arc bottom width B is 5mm 〉=B 〉=0.01mm.

Preferably get:

(1)1.2mm≥B≥0.15mm；

(2)0.3mm≥h1≥0.05mm；

(3)3mm≥h2≥0.2mm。

Like this, the effect of perspective piece is better, and the multidimensional impressions of image is more suitable for naked eyes and regulates apart from burnt.

Desirable PP of the material of perspective piece or PVC or PETG or PS or APET or PC or APPM or other plastics.

About the color of perspective piece, desirable colourless or colourful transparent material.

About the transmittance of perspective piece, the material of desirable different printing opacity degree.

With reference to Fig. 1,3,4,5,6,7,8 and Fig. 9, adopt plastic perspective sheet of the present invention as dioptric lens, have the picture of three-dimensional impression by the prior art manufacturing.With as shown in Figure 5 pattern (being designated hereinafter simply as pattern D) is example, described plastic perspective sheet can be used as the dioptric lens that covers pattern C or pattern D front surface, the plane 11 of this plastic perspective sheet is adjacent with pattern C or pattern D front surface, pattern D or pattern C can be as shown in Figure 8, directly be printed on the very thin color-printed layer 2 of formation on the plane 11, also the flat board 3 that can be printed on other in advance with reference to Fig. 9 (for example: three-ply board, sheet metal, plastic plate or the like) surface, with reference to Fig. 1 and Fig. 5, when the plane 11 of plastic perspective sheet is pressed close to cover mutually as shown in Figure 9 with the flat board 3 with pattern D or pattern D is printed when covering on the plane 11 as shown in Figure 8, vertical mark of Fig. 1 and vertical mark of Fig. 5 are in correspondence with each other, the picture of forming three-dimensional impression, audience's sight line is passed described convex face 12, the person has three-dimensional impression to make the viewing graphic pattern, with reference to Fig. 1 and Fig. 4, the person has three-dimensional impression in like manner to make the viewing graphic pattern.

With reference to Fig. 6, when the arc of convex face 12 is that (arc of convex face 12 and dotted line are formed described ellipse to an oval part, described dotted line only supplies the source of the arc of synoptic diagram convex face 12 in the drawings), and, with reference to Fig. 7, the symcenter of described ellipse is O, and the mid point of the arc of convex face 12 is G, E=2GO, E＞F.Rocking of described three-dimensional impression feels little, and especially when sight line was seen the chart board of the described three-dimensional impression on the wall and moved, little (for example, rocking of the three-dimensional impression of image feels little) felt in rocking of described three-dimensional impression.

Use the method for plastic perspective sheet as the cosmetic sheet in building board field, its concrete practice is as follows:

(1) plastic perspective sheet 1 is coated with color-printed layer 2 as dioptric lens on the plane 11 of plastic perspective sheet 1, and vertical mark of the vertical mark of plastic perspective sheet 1 and the pattern of color-printed layer 2 is also formed the picture with three-dimensional impression in correspondence with each other;

(2) described picture with three-dimensional impression is arranged on the position, place of the cosmetic sheet on building board surface, some described pictures with three-dimensional impression is spliced with reference to Figure 10 by the big I of area.A lip-deep described straight line 13 of every picture with three-dimensional impression is all parallel to each other.

Best, the straight line 13 on the surface of plastic perspective sheet 1 is perpendicular to surface level, and is orthogonal with audience's eyes line.Described variation vision is the three-dimensional vision that changes.

Best, have the picture of three-dimensional impression perpendicular to the cosmetic sheet that three dimensional change vision arranged of surface level with described as wall surface.

Best, get the three-dimensional cosmetic sheet that changes vision that has in the cosmetic sheet of described three dimensional change vision.

With reference to Fig. 7, Figure 11 and Figure 12, described ellipse can adopt the shape of multiple variation.
