Definitions

  • the present invention relates generally to decorative elements and more generally decorative elements such as those used as hubcaps at the ends of curtain rods, curtain bases, but also as door handles, hinges, or even as hubcaps of gate grids.
  • Wood or plastic are rarely used because they do not provide much sought after aesthetic effects.
  • Brass is a material which not only is expensive, but which also requires extensive polishing so that the decorative elements in this material are very expensive and not widespread.
  • Wrought iron is heavy, which often requires special fixings for the installation of decorative elements. It is also subject to rust, which means that it has to be maintained very regularly. It is also difficult to work so that the pieces made of wrought iron can only have relatively simple shapes. Wrought iron parts are therefore rather expensive.
  • the present invention relates to aluminum decorative elements and more particularly such objects whose appearance is that of wrought iron.
  • the invention indeed provides a method for making decorative products having the particular appearance of wrought iron from a soft metal, such as for example cast aluminum.
  • the present invention thus makes it possible to economically produce decorative elements, made of aluminum, which have the external aesthetic appearance of wrought iron or a similar forged hard metal.
  • the method according to the present invention consists in operating in the following manner:
  • a blank is made of cast aluminum by casting in a mold.
  • This blank can also be produced by cold deformation or by compression. This shaping process allows the realization of almost any shape with great ease which makes them inexpensive.
  • the part is subjected to brushing.
  • This brushing operation is carried out superficially so as to remove the paint on the raised parts of the part while leaving it to remain in the hollow parts.
  • the part thus treated is covered with a protective varnish in order to keep the paint in place in the hollow parts.
  • the part after the hammering operation, the part is covered with a first layer of paint (golden for example) and after drying of this layer, it is covered with a second layer (green for example); then we proceed to the surface brushing so as to remove the second layer of paint only in the projecting areas and not in the hollow areas: we then obtain a very particular decorative aspect.
  • a first layer of paint golden for example
  • a second layer green for example
  • Hammering can be carried out by any known means, for example by placing the parts inside a rotating drum or barrel in which steel balls are arranged.
  • this mixing operation in a barrel in the presence of steel balls prints marked depressions on the surface of the parts, depressions which will then highlighted by subsequent painting and brushing operations.
  • the invention is therefore not limited to the use of cast aluminum: this process can be applied to all metals of low hardness such as zamak, copper, zinc or tin.
  • metals such as copper, zinc or tin are too expensive, which makes cast aluminum or zamac preferable.
  • curtain rods which are made of steel tube strong enough to support the weight of the curtains at the ends of which are fixed hubcaps having quite the appearance of wrought iron but being made of aluminum or in zamak treated according to the process described above which makes them light, stainless and inexpensive.
  • the present invention therefore also relates, as new products, to all decorative products having the appearance of wrought iron obtained (at least partially) according to the process described, whether used alone or in combination with other elements.
  • the invention also covers all the variants of processes and products produced at least partially in soft material, in which the hammering of the soft material is carried out by impact of a hard material (steel, glass, etc.) and a partial coating is after hammering.
  • a hard material steel, glass, etc.
