摘要

Adjustable protective cover is applicable to devices that have a keyboard or Keypad, formed by a pair of Thermoplastic foils (10. 20) that define a tubular Body deformable opened at their ends (3, 4).The Blade (10) is the top sheet and is Translucent, while the lower (20) has a Plurality of Pleats (21) with zigzag edges and longitudinal Ribs (22) in its external edges. Each RIB (2) defines a Center of Resistance to Elastic deformation determined by the introduction of a control Body (6) to the Interior of the tubular Body (5).
