FIELD: personal utensils. ^ SUBSTANCE: invention pertains to commodities for children and may be used for manufacture of wall photo frames. At first, a part of the top layer of the parent material in the plan view having a rectangle, a quadrate, a circle or an ellipse, or an hexagon shape is taken away with the milling instrument of the cutting plotter in the parent sheet of the expanded polyethylene or in the sheet of bilaminate two-colour expanded polyethylene. A through rectangle, quadrate, circle or an ellipse, or an hexagon - shaped hole is made by contour in the shaped part of the parent material with a cutting tool of the plotter, threat its biggest cross dimensions are maintained in orthogonal axes dx0 and dy0 against similar dimensions of the shaped part of the parent material dxc and dyc within the range of 0.1dxcëñdx0<0.95dxc, 0.1dycëñdy0<0.95dxc. Thereafter, childish photo frame with the required contour of the outside perimetre is cut out of the parent material with the cutting tool of the plotter enveloping shaped part of the parent material at a certain distance; wall mount through holes are made in the photo frame. Fixing frame with the outside perimetre similar to that of the shaped part of the childish photo frame and internal through rectangle, quadrate, circle or an ellipse, or an hexagon - shaped opening is cut with cutting tool of the plotter from the other part of the parent material and inserted until it stops with its entire surface against the shaped part of the childish photo frame. The biggest external cross dimensions in orthogonal axes of the fixing frame dxf and dyf are maintained in the range of dxc<dxf<1.1dxc and dyc<dyf<1.1dyc), correspondingly, and the biggest internal dimensions in its orthogonal axes dxo and dyo are maintained in the range of 0.5dxc<dxo<0.99dxc and 0.5dyc<dyo<0.99dyc, correspondingly. ^ EFFECT: injury free operation and possibility of rapid alternation of the exhibited photo. ^ 3 dwg |
