Description
BACKGROUND OF THE INVENTION
1. Field of the Invention

The present invention relates to the field of garage doors and in particular to the hinges located between garage door panels to enable the sectional garage door (made up of three or more sections) to roll on tracks above the interior of the garage and down on tracks and back into its vertical position in front of the interior of the garage.


2. Description of the Prior Art

There is a need for an improved and quieter garage door hinge. The industry standard hinge has not changed very much over the past 50 years. One change has been to change the shape or thickness of the garage door hinges. Some manufacturers have made changes such as removing some material from the hinge such as a small scallop on the edge of the hinge.


Some manufacturers have made plastic hinges for wet environments such as car wash doors. Some have been advertised to be quieter and offer lower maintenance but the drawback to using plastic hinges is that they cost more than metal hinges and do not have the same strength as galvanized steel hinges.


There is significant need for a quieter garage door hinge.


SUMMARY OF THE INVENTION

The present invention is an improved quieter garage door hinge. The standard galvanized steel garage door hinges allow the sectional garage door (made up of three or more sections) to roll up above the garage interior and roll down in front of the garage interior with the support of steel tracks. Each section bends and pivots while rolling through the radius of the track. Without the use of the garage door hinges, the door would not have the flexibility to follow the turn (radius) in the track.


The problem with the standard garage door hinges is that they are noisy, even after lubrication. Industry standard hinges have a very loose design where the barrel inside of the hinge moves side to side, causing the loud rattling noise that is heard when the door is in motion. Even the use of lubricants is not enough fill the void in the hinge to stop the noise.


The present invention is to incorporate two hard thermoplastic injection molded washers such as Delrin injection molded washers placed between the two halves of the hinge and slide it over the hinge barrel. This provides a friction reducing pivot point and holds in lubricant. The present invention improvement will hold the barrel in place and reduce the problem of the barrel moving side to side. The present invention improvement will stop or at least significantly reduce the extra noise and provide smoother operation of the hinge.


In addition, the hinge must be made with tighter tolerances than the conventional hinges. This will allow the hinge to still move freely but not move back and forth and clack while the sections are rolling up and down.


An additional improvement of the present invention is to crimp and expand the hinge barrel very tight and not allow it to rotate such as other hinge designs currently in the market. A locked hinge barrel paired with the Delrin washers and tighter hole tolerance will improve the function of the hinge and enable the hinge to be more quiet than prior art hinges and function more smoothly as compared to the industry standard design for garage door hinges.


In summary, the main objects of the present invention are:

    • (1) to incorporate two spaced apart washers selected from the group consisting of Delrin, hard thermoplastic injection molded washers and washers made of solid material, the first washer slid around the hinge barrel and positioned between a first arm of an exterior hinge plate and a second arm of an interior hinge plate, and with a second washer slid around the hinge barrel and positioned between a first arm of an exterior hinge plate and a second arm of an interior hinge plate to reduce noise;
    • (2) to provide tighter hole tolerances to reduce noise; and
    • (3) incorporate the improvement into galvanized steel garage door hinges.


Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.
