Definitions

  • the present invention relates to a writing board with a writing plate having a continuous writing surface.
  • Writing boards of the type mentioned at the outset have proven themselves in practice for visualizing ideas and for supporting communication between members of a team.
  • Such writing boards usually have a continuous or planar writing surface, that is to say a writing surface designed without interruptions, which can be written on and then wiped off with pens or markers.
  • the writing surface can be a substantially rectangular surface his.
  • such writing boards are relatively heavy and bulky.
  • the use of modern creative methods and approaches such as design thinking, agile work or serum requires not only to be able to quickly record information, but also to be able to rearrange it continuously and flexibly. For example, to be able to quickly present the results of a brainstorming session in another office.
  • the object of the invention is to provide a writing tablet which can be used flexibly and is portable. At the same time, high stability is required.
  • a writing tablet of the type mentioned at the outset in that the writing tablet has a stiffening plate and a carrier plate arranged between the writing plate and the stiffening plate, the carrier plate being made, in particular, from an expanded polypropylene.
  • Such a writing tablet according to the invention is light in weight and nevertheless stable.
  • the carrier plate forms the "core" of the writing board, while the writing plate and the stiffening plate are spaced apart from one another by the carrier plate and form the "cover layers".
  • Such a sandwich-like structure is characterized by high bending stiffness and low weight. This will Favored in particular in that the carrier plate is made of an expanded polypropylene, which is heavy-duty and yet light.
  • the sandwich-like structure of the writing board gives it a special degree of stability that goes far beyond the stability of the individual components.
  • the writing plate and the stiffening plate are each subjected to tensile stress when the writing tablet is subjected to bending stresses and, taken on their own, can be designed to be very tensile but not very rigid.
  • the carrier plate which can preferably be at least 5 times, in particular 10 times, as thick as the writing plate or the stiffening plate, spaced the two plates apart from one another, so that one or the other is loaded under tension in the event of a bending load.
  • the writing board can be designed to be very light, yet rigid and dimensionally stable.
  • a writing tablet according to the invention can be transported by only one person without great effort. This is particularly advantageous if the writing board should be regularly and flexibly rearranged in different positions, as is required, for example, when working in multidisciplinary, self-organizing teams. Due to the high flexural rigidity, the tablet is particularly robust, which - even with regular transport - enables a long service life of the tablet.
  • Expanded polypropylene may refer to a material made by inserting polypropylene beads into a mold and heating them with steam. By heating and applying pressure, the individual polypropylene beads can combine to form a solid material. Expanded polypropylene is light and yet highly resilient. In addition, expanded polypropylene can be easily removed from the mold, since it can be plastically deformed temporarily. This enables the carrier plate to be produced easily.
  • the writing surface is designed as an enamelled sheet. As a result, a robust, in particular scratch-resistant, writing surface is achieved which can be wiped off permanently. This is advantageous for a high rewritability of the writing surface. It is particularly preferred if the writing plate is made of a ferromagnetic steel sheet. This makes it possible, for example, to detachably attach notes or signs to the writing surface by means of magnets.
  • the writing plate can be formed using a plastic plate, in particular consist of a plastic plate. It is particularly preferred if the plastic plate comprises melamine resin (melamine-formaldehyde condensation resin), in particular consists of melamine resin. Melamine resin is characterized, among other things, by high weather resistance and scratch resistance with a relatively low weight. This contributes to one long life of the tablet. Transport of the writing board is also facilitated.
