Description

FIELD OF THE INVENTION [0001] This invention relates to the design and construction of a novel, self-contained, retractable screen unit that may be mounted to any railing system, fence or existing structure to provide additional safety and security. BACKGROUND OF THE INVENTION [0002] Retractable screens exist in various forms serving various functions and are well known in the prior art. Conventionally and ubiquitously, retractable screens that are capable of being mounted to railings, fences or existing structures have been used for the limited purpose of providing decoration and privacy by screening off areas that would otherwise be open to view. The benefit these types of retractable screens provide is that they are typically simple to form and relatively inexpensive. However, as a result, retractable screens are also typically flimsy when extended and can easily be pushed forward with very little force, thus providing no security or safety effect. [0003] Historically, the answer...

Benefits of technology

[0005] The inventive structure presents a number of advantages over the prior art. First, the invention is simple to form. The retractable screen unit includes a housing unit made in various shapes and of suitable materials, preferably PVC or rust resistant metal. The housing unit contains a tension rod. The tension rod is utilized to draw out and retract the screen from and to the housing unit. The tension rod also has securing means that allow the tension rod to secure itself to an additional housing unit. The tension rod is capable of being removed and replaced with another tension rod. This feature eliminates the need to replace an entire housing unit in the event the tension rod and / or screen needs to be replaced.

[0006] The additional housing unit may be empty to serve only the purpose of securing the retractable screen, or the additional housing unit may contain another screen to allow the screened area to be extended. Each housing unit also contains a locking means, which locks the screen in place when the screen is extended to prevent slack in the event force is applied directly to the screen. In the preferred embodiment, the locking means is a metal strap that surrounds the outside of the housing unit. The metal strap has two prongs with plastic extended buttons on one prong and open holes on the other prong, which connect and grasp the screen between the prongs. This provides another distinct advantage over the other relatively simple, inexpensive prior art in that the locking means provides additional security and safety by preventing the screen from being pushed forward.

[0008] The screen may be made of suitable, durable materials, including sunscreen fabric, Vinyl or other weather resistant fabric for exterior use and non weather resistant materials for indoor use, which are durable and may not be easily ripped or torn. The screen may also be removable from the tension rod and replaceable with another screen. This feature provides the advantage of not having to replace the entire housing unit should the screen need to be replaced for wear or aesthetic reasons.

Problems solved by technology

However, as a result, retractable screens are also typically flimsy when extended and can easily be pushed forward with very little force, thus providing no security or safety effect.

Although fences and railing provide a degree of safety by preventing people and objects from entering a restricted area, they do not address the inherent dangers posed by the fences and railings themselves.

For example, children or small pets have been known to become lodged in or pass over fences and railings causing serious harm and even death.

Moreover, fences and railings are capable of being compromised over time or during adverse weather conditions, which has led to the unexpected collapse of fences and railings while people were leaning on the structures.
