Ever opened and closed a door and pinched yourself on the hinge? Painful isn't it? Well, the same can happen with garage doors, only these injuries can be much more serious. That's why there are pinch-resistant garage door hinges. They are designed to prevent accidents where you pinch your fingers when making repairs, such as placing fingers near the door's section joints. The pinchless hinges are typically used on upward sectional doors as found on garages, warehouses, airplane hangars and other structures where there is a large door opening that needs to be opened and closed selectively. The selective opening and closing is for the purpose of security so that only authorized people can gain access.
Do sectional upward doors need pitch-resistant hinges?
Sectional upward doors are typically made of a number of horizontal sections that are held together by hinges. When a door has pinch-resistant hinges and joints, the hinges have a high quality fixture that can be secured to the upper panel and another one that can be secured to the lower panel.
These security fixtures on the upper and lower panels are held together with links. Each link has one end that is fixed to the upper panel and another to the lower panel. The way the links are placed ensures that the upper panel is spaced closely enough to the lower one such that it's not possible for a person to insert their fingertip into the joint. There is also an elongated foot that pushes away a fingertip away from the joint when the door is closing. There is also a door seal on each of the panels which moves to engage the adjacent panel when the door is closed. The seal lifts away as the door opens.
What about standard hinges?
The challenge with standard hinges on upward opening sectional doors is that their pivot pins are typically placed outwards not inwards. This creates gaps that are quite large on the outside which tend to come together in a fold when the door is being door closed. Many people tend to hold the door by the edges of the sections to pull it shut rather than by the handle. The fingers can get pinched between the door sections as they come together when the door is closing. This can result is some serious and painful hand injuries.
Before pinch resistant hinges were introduced, there were a number of attempts to eradicate this problem. One such solution was to move the pivot pin of the door hinge to a different location between the interior and exterior panels. Another was to design doors such that the top and bottom surfaces rotating while remaining close to each other so that there was no gap that was large enough for a finger to fit through when the door is being pulled shut or opened. Both of these solutions did not work because doors with these designs were expensive and difficult to construct.
Another solution that was put forth was to design doors with single metal panels and no insulation to that opening and closing the door was not a problem. This meant using insulated door pockets but this also flopped because the pockets made the door weak and reducing its insulation and energy efficiency.
