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.
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.
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:
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.
Referring particularly to the drawings for the purpose of illustration only and not limitation, there is illustrated:
Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims.
Key improvements of the present invention is an addition to reduce noise made by a garage door hinge by incorporating two washers with a respective first washer slid over the hinge barrel at a location between adjacent arms on a first side of the two hinge plates and a respective second washer slid over the hinge barrel at a location between adjacent arms on a second side of the two hinge plates and through which arms the hinge barrel extends. This provides a noise reduction improvement by avoiding metal to metal contact between adjacent hinge plate arms and also reduces movement of the hinge barrel. This also creates a friction reducing pivot point and holds in lubricant. An additional improvement is to hold the barrel in place and reduce the problem of the barrel moving side to side. The improvement will stop or at least significantly reduce the extra noise of the garage door hinge as the garage door moves and provide smoother operation of the hinge.

Opening 354 and 364 are aligned. The 300 series of numbers refer to the prior art exterior attaching plate 310.
The prior art exterior attaching plate 310 and the prior art interior attaching plate 210 are aligned so that prior art first arm 350 is exterior to and aligned with prior art second arm 260 with openings 354 and 264 aligned and prior art second arm 360 is exterior to and aligned with prior art first arm 250 with openings 364 and 254 aligned. A hinge barrel 400 having a cylindrical barrel portion 402 and a stopping plate 404 extends through aligned openings 354, 264, 254 and 364 to rotatably retain the prior art exterior attaching plate 310 and the prior art interior attaching plate 210 together to form prior art hinge 200. Each prior art attaching plate can optionally have a scalloped portion 205 and 305. A first gap 410 is between first arm 350 and second arm 260. A second gap 420 is between second arm 360 and first arm 250. Gaps 410 and 420 contribute to the noise by metal to meta contact between respective adjacent arms 350 and 260 and between respective adjacent arms 4360 and 250.
The prior art hinge 200 is positioned between two adjacent garage door panels so the hinge barrel 400 is positioned in the gap between two adjacent garage door panels, and one attachment plate is affixed to one garage door panel and the other attachment plate is affixed to an adjacent garage door panel. A multiplicity of hinges are respectively affixed to two adjacent pairs of garage door panels, with each garage door panel hingeably attached to an adjacent panel by a hinge 200.

The exterior attaching plate 10E and the interior attaching plate 10I are aligned so that first arm 50E is exterior to and aligned with second arm 60I with openings 54E and 64I aligned and second arm 60E is exterior to and aligned with first arm 50I with openings 54I and 64E.
A hinge barrel 100 has a cylindrical barrel portion 112 with an outer wall 114 surrounding interior opening 115 and a stopping plate 116. The outer wall 114 is sized to enable the hinge barrel portion 112 to extend through aligned openings 54E, 64I, 54I and 64E has to rotatably retain the exterior attaching plate 10E and the interior attaching plate 10I together to form hinge 5. Each attaching plate can optionally have a scalloped portion 905E and 905I. Each opening 54E, 64I, 54I and 64E has a first diameter “AD−1”. The outer wall 114 of cylindrical barrel portion 112 has a diameter “BHD−1” which enables the cylindrical barrel portion 112 to be inserted through openings 54E, 64I, 54I and 64E has. The stopping plate 116 is integral with and extends around and outwardly from a first end 112F of the cylindrical barrel portion 112. The stopping plate 116 has a transverse wall 118 which has a diameter “TVD−1” which is larger than diameter “AD−1”.
A key innovation of the present invention is to place a first washer 120 having a body 122 with a central opening 124 having a diameter “WD−1” which is larger than “BHD−1” around outer wall 114 of the barrel portion 112 of hinge barrel 110 and to also place a a second washer 130 having a body 132 with a central opening 134 having a diameter “WD−2” which is larger than “BHD−1” around outer wall 114 of the barrel portion 112 of hinge barrel 110. The first washer 120 and the second washer 130 are each selected from the group consisting of Delrin, hard thermoplastic injection molded washer, and or washer made of solid material. First washer 120 has lubricant LB1 on exterior face 126 and interior face 128. Second washer 130 has lubricant LB2 on interior face 136 and exterior face 138.
The present invention hinge is assembled by having the exterior attaching plate 10E and the interior attaching plate 10I are aligned so that first arm 50E is exterior to and aligned with second arm 60I with openings 54E and 64I aligned and second arm 60E is exterior to and aligned with first arm 50I with openings 54I and 64E the hinge barrel 100 is inserted so that cylindrical barrel portion 112 is inserted through first exterior arm opening 54E, first washer 120 is inserted onto cylindrical barrel portion 112, the cylindrical barrel portion 112 is inserted through second interior arm opening 64I and through first interior arm opening 54I, the second washer 130 is inserted onto cylindrical barrel portion 112 and the cylindrical barrel portion 112 is inserted through second exterior arm opening 364 with stopping plate 116 preventing further insertion of the cylindrical barrel portion 112 of hinge barrel. At its opposite end, cylindrical barrel portion 112 is crimped 116A to lock the hinge barrel 110 in place. Therefore, first washer 120 separates first arm 50E and second arm 60I and second washer 130 separates first arm 50I and second arm 64E. By eliminating arm to arm contact and therefore metal to metal contact, the noise of the hinge 5 is substantially reduced and the panel attaching plates 10E and 10I rotate relative to each other as the garage door is rained and lowered.
The first washer 120 and the second washer 130 are each selected from the group consisting of Delrin, hard thermoplastic injection molded washer, and or washer made of solid material)
