The only feature, which unites this invention with the traditional overhead model, is their common type of designs with sectional type of door. In other words, the doors are technically formed in both constructions from sectional panels. The rest in this model is new as well as its acquired characteristics.
Firstly, the model is fully compact. These sectional panels are accordion folded at the top of the opening and finally they take a little space and don't hang over your head - unlike the traditional ones.
Secondly, there are no torsion springs, the potential dangerous elements which can be the source of injuries for their owners as it is in the traditional model. Accidents of this kind occurred in the history of exploitation of these doors.
And the last, the third difference, which is not reflected in the patent, because any new thing reveals all its properties not at once - is the possibility to replace panels on the new construction. If the traditional model has parameters of torsion spring strictly corresponded with weight of all sectional panels which can not be changed, than the weight of panels in the innovation model can vary in a broad range. And moreover it can reach 250 kg (with cable diameter of 2 mm), what is three times more than it is admissible for traditional construction with standard size of panels. So, here the weight of door can vary in wide range, having no impact on the other construction characteristics. It means that sections can be produced from various materials - plastics, wood, metal, glass.
Therefore, the sectional folding up garage door, among other advantages such as full compactness and lack of torsion springs, has additional attractive innovation - the removability of its sectional panels. For instance today you have a glass door, over a year a wood, etc. You should buy only a basic design and change the panels whenever you want. It is economical, comfortable and innovative solution at the same time.
