ABSTRACT:
A cover for a computer keyboard comprises a sheet of elastic elastomeric material such as polyester film of sufficient length and width to cover a keyboard, which is of sufficient rigidity to retain a cylindrical shape when rolled and to cover the keyboard top and at least two opposing sides of the keyboard when unrolled. The cover is formed by rolling the sheet into a tight roll and then heating the rolled sheet for a sufficient time at a sufficient temperature such that when cooled, it will possess a curl characteristic retaining memory of its rolled condition, then cooling the material. The sheet may be formed in a roll which is oriented to extend and roll up from either the left hand side or right hand side of the keyboard. The two long edges extend past the edges and grip the side or underside of the keyboard. In another embodiment, the sheet is cut to form a roll which is oriented top to bottom relative to the keyboard face or front. The keyboard cover will roll automatically into a compact, conveniently-storable roll. An adhesive strip may be provided along one edge in order to hold it against the keyboard when the cover is not in use.
