Definitions

  • the invention relates to a method for manufacturing a distorting mirror, the distorting mirror thus manufactured, and a kit comprising the distorting mirror.
  • the field of the invention relates to mirrors which can be suspended from a support and which can have an aesthetic, decorative or playful or entertainment function, for example in places open to the public, or other.
  • Such deforming mirrors having an S-deformed surface are known.
  • An objective of the invention is to obtain a method of manufacturing a deforming mirror, a deforming mirror thus manufactured, as well as a kit comprising the deforming mirror, which overcome the disadvantages mentioned above of the state of the technical.
  • the folding operation makes it possible to generate non-uniform deformations of the curved plate from the rectilinear edge to make the reflective deformation of the mirror non-uniform.
  • the invention can, in the same mirror, present variations in reflective effect from top to bottom and from left to right at the same time. In doing so, the folding operation makes it possible to somewhat attenuate the curvature due to bending, which makes it possible to obtain a less pronounced reflective deformation of the mirror, making it possible to partially recognize the real object, reflected by the mirror.
  • the folded edge thus makes it possible both to straighten to a certain extent the deformation of the front face near the folding edge to obtain the reflective deformation mentioned above and to possibly serve as a support for a suspension element of the distorting mirror.
  • the manufacturing process according to the invention makes it possible to save space and weight of the mirror and to avoid the limitations of the state of the art.
  • the bending is carried out along the first determined direction, in which the plate extends, and/or along a second determined direction, in which the plate extends and which is perpendicular to the first determined direction.
  • the bending during the first step then the folding during the second step creates on the reflective front face at least one convex zone juxtaposed with at least one concave zone along the first determined direction .
  • the bending during the first step then the folding during the second step creates on the reflective front face at least one convex zone juxtaposed with at least one concave zone or a single convex zone or one single concave area along the second determined direction.
  • the first determined direction is substantially parallel to one end of the plate.
  • the folding of at least one edge of the plate towards the rear of the reflective front face along the rectilinear folding edge extending along the first direction determined during the second step is carried out using a press brake, by pressing the plate between a die of the press brake and a punch of the press brake.
  • the folding of at least one edge of the plate towards the rear of the reflective front face along the rectilinear folding edge extending along the first direction determined during the second step is carried out such that the width of the edge between the free end of the edge and the rectilinear folding edge is non-uniform along the rectilinear folding edge.
  • the folding of the edge of the plate is substantially at right angles towards the rear of the reflecting face along the rectilinear folding edge.
