Consumable and disposable cartridges for laminar screens featuring straight and curved shapes

Abstract

Consumable and disposable cartridges (200) for laminar roller screens featuring quick installation and replacement by means of clip type means (41) or the like. They comprise a flexible sheet (15) which can change between a straight lined, curved or right angled path by means of cylindrical tubular means (40) or the like. They are associated to peripheral frames of the open space to be enclosed. Inside of it there is a rotation drum (5) for a flexible sheet, a torsion spring (12) causing the rotation drum to rotate so as to roll the sheet and a tubular element being of the same height as the sheet. There is also an actuation knob (13) which regulates the spring tension, and a tubular casing (6) delimiting the cartridge from which the sheet goes in and out. It further comprises anchoring and guiding means of the spring inside the drum, and a cover (28) of the casing to receive the detachable coupling of the actuation knob.

Description

technical field [0001] The present invention relates to a consumable and disposable cartridge system, characterized by quick installation and replacement by the user without tools or professional help, to realize any type of layered curtains, applied to mosquito nets, awnings, door curtains And curtains, bathroom and shower curtains and other similar applications. Background technique [0002] Currently, there are many different shades applied on the bathroom and shower side to prevent water from splashing outside the area defined by the brick and mortar work wall and the shade itself. Typically, these shades have a peripheral frame to which elements are mounted which, in use, enclose the interior space. [0003] In some cases, these closing elements consist of openings or sliding panels, usually made of glass, mounted on rails defined by the upper and lower uprights of the frame. When these panels overlap, only a partial opening is left for the user entrance, and when the...

AI Technical Summary

Problems solved by technology

[0011] Even when these designs have means for servicing any element, said operation cannot be performed simply or quickly, nor can it be performed by the user himself, since it requires qualified professionals

Said qualified personnel must first determine the specific problem and then repair or remove the part and replace it with one of the many closures commercially available at great expense and after a lengthy period of time
