ABSTRACT:
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a bound paper element, such as a notebook, index book, book or manual, note-block or similar.
Description of the Related Art
Such paper elements as the above (which for brevity will hereafter be referred to by the term “notebook”) are well known and in common and frequent use, and for such reasons are constantly found on desks and worktops in offices and workshops. These worktops are occupied, not only with paperwork and other objects of work, but also by many other devices: computers, printers and similar machines.
Brief Summary of the Invention
An example of a known paper element according to the preamble of claim
1
is disclosed in U.S. Pat. No. 5,405,168, which relates a mouse pad or note pad comprising a stack of textured paper sheets secured to a substantially rigid base, the latter providing friction with respect to a support surface. In particular, the work surface of each paper sheet is a rough writing surface upon which notes can be written, even if not very neatly. The top paper sheet which provides the working surface can be removed after an extended amount of use in order to allow a proper contact between the track ball of the mouse and the textured surface of an underlying sheet.
Another example of a mouse pad is disclosed in FR-A-2685112. This mouse pad comprises a base element covered by a plurality of sheets made of paper or plastic material, each of which is provided with a thin coating of replaceable glue on the bottom side. Also in this case, the top sheet is removable when the working surface of the same is no more able to assure a proper operation of the mouse.
A similar solution is disclosed in GB-A-2289520, which relates to a mouse pad in which the top paper sheet is removed whenever necessary in order to reveal a clean top surface of an underlying sheet.
DISCLOSURE OF THE INVENTION
The purpose of the present invention is to modify such elements, or notebooks, to adapt them for an additional use, in order to reduce the space occupied on the worktops.
Such purpose is achieved by means of the present invention, which relates to a bound paper element comprising a plurality of bound pages, and at least a first page and a second page arranged at opposite extremities of at least part of said plurality of pages, characterised in that the first page is constituted by, or comprises, a layer in an embossed plastic material and the second page is constituted by, or comprises, a layer in an expanded thermoplastic material; and that the layer in embossed plastic material of the first page is arranged opposite to the layer in expanded thermoplastic material of the second page.
The first page provides therefore a layer having a controlled-friction surface, namely a surface suitable to support a computer mouse and to allow controlled and precise movements. Surfaces of this type are produced in embossed plastic (e.g. PVC, PP or PE), particularly with cusp-embossing. The second age provides a layer with a “non-slip” function in order to avoid the movement of the bound paper element with respect to a supporting plane.
According to another aspect of the invention, the first and the second page are internally provided with at least one layer made of material having a coefficient of friction to maintain them substantially fixed with respect to the underlying pages.
According to a further aspect of the invention, the angles of the notebook are rounded.
