Abstract

Disclosed is a long arm quick release hinge comprised of a hinge cup pivotally connected to a hinge body with a hinge pin via a hinge arm and a link in a four-bar linkage arrangement. The link is a collection of plates with interlocking projections and indentions arranged adjacent to each other and separated by resilient shock absorbing spacers. The hinge body is adjustably connected to a connecting plate with an overlay screw and an adjustment screw.

Claims

1. A hinge assembly comprising:

a hinge body having a generally U-shaped cross section comprised of an upper surface and a first side and a second side, where the first side and the second side each include a pivot hole;

a pivot pin inserted through the pivot holes;

a hinge arm pivotally connected to the hinge body and a hinge cup;

a link pivotally connected to the hinge cup and pivotally connected to the hinge body via the pivot pin, where the link is comprised of a first set of plates, a second set of plates, and a third set of plates;

a first spacer, coaxially aligned with the pivot pin, adjacent the first side and the first set of plates;

a second spacer, coaxially aligned with the pivot pin, adjacent the first set of plates, an edge of the second set of plates, and the third set of plates; and

a third spacer, coaxially aligned with the pivot pin, adjacent the third set of plates and the second side.

2. The hinge assembly of claim 1 wherein each plate of the first set of plates, the second set of plates, and the third sets of plates is arranged side by side.

3. The hinge assembly of claim 1 further comprising:

a projection of a first plate of the first set of plates engaged with an indention of a second plate of the first set of plates;

a projection of the second plate of the first set of plates engaged with an indention of a first plate of the second set of plates;

a projection of the first plate of the second set of plates engaged with an indention of a second plate of the second set of plates;

a projection of the second plate of the second set of plates engaged with an indention of a first plate of the third set of plates; and

,

a projection of the first plate of the third set of plates engaged with an indention of a second plate of the third set of plates.

4. The hinge assembly of claim 1 wherein a first plate of the first set of plates has a first hole and a second hole and wherein a first projection on a second plate of the first set of plates engages the first hole and a second projection on the second plate of the first set of plates engages the second hole.

5. The hinge assembly of claim 1 wherein each plate of the first set of plates, the second set of plates, and the third sets of plates is arranged side by side and further comprises a pair of projections on a first side and a pair of indentions on a second side.

6. The hinge assembly of claim 1 further comprising:

a pair of projections of a first plate of the first set of plates engaged with a pair of indentions of a second plate of the first set of plates;

a pair of projections of the second plate of the first set of plates engaged with a pair of indentions of a first plate of the second set of plates;

a pair of projections of the first plate of the second set of plates engaged with a pair of indentions of a second plate of the second set of plates;

a pair of projections of the second plate of the second set of plates engaged with a pair of indentions of a first plate of the third set of plates; and

,

a pair of projections of the first plate of the third set of plates engaged with a pair of indentions of a second plate of the third set of plates.

7. The hinge assembly of claim 1 wherein the first spacer, the second spacer, and the third spacer each has a generally circular cross section and is rotatable about the pivot pin.

8. The hinge assembly of claim 1 wherein the first spacer, the second spacer, and the third spacer are formed of semi-rigid plastic polymer.

9. The hinge assembly of claim 1 wherein the first spacer, the second spacer, and the third spacer have a cross section chosen from the group of circular, rectangular, and oblong.

10. The hinge assembly of claim 1 further comprising:

the upper surface further including a first threaded hole and an oblong hole;

a connecting plate having a generally U-shaped cross section comprised of a base surface including an open slot and a second threaded hole;

an overlay screw comprising a threaded section for threadably engaging the first threaded hole, a shaft extending from the threaded section, and a disk formed on the end of the shaft;

an adjustment screw extending through the oblong hole and threadably engaged with the second threaded hole;

wherein the connecting plate is adjustably connected to the hinge body as the shaft extends through the open slot and the disk is adjacent the connecting plate and the adjustment screw extends through the oblong hole and engages the second threaded hole;

wherein to make an overlay adjustment, the overlay screw is rotated such that a relative lateral distance between the hinge body and the connecting plate is altered; and

,

wherein to make a horizontal adjustment, the adjustment screw is rotated and a horizontal position of the hinge body relative to the connecting plate is altered.

11. A method of increasing shock absorption in and eliminating deformation of a hinge during loading comprising:

providing a hinge cup, a hinge body, a set of interlocking plates connecting the hinge cup and the hinge body, and a hinge arm adjacent the set of interlocking plates and connecting the hinge cup and the hinge body, forming a 4-bar linkage arrangement;

arranging each plate of the set of interlocking plates side by side where a first projection of a first interlocking plate of the set of interlocking plates engages a first indention of a second interlocking plate of the set of interlocking plates;

providing a set of resilient spacers coaxially aligned on a pivot pin, resiliently connecting the set of interlocking plates to the hinge body;

arranging a first resilient spacer of the set of resilient spacers adjacent the first interlocking plate of the set of interlocking plates, the second interlocking plate of the set of interlocking plates, and a third interlocking plate of the set of interlocking plates; and

,

wherein vibration of each plate of the set of interlocking plates relative to each plate of the set of interlocking plates is reduced and impact movement of each plate of the set of interlocking plates relative to each plate of the set of interlocking plates is allowed.

12. The method of claim 11 wherein the step of arranging each plate of the set of interlocking plates further comprises providing a plurality of interlocking plates.

13. The method of claim 12 further comprises providing the first interlocking plate of the set of interlocking plates with a first hole and a second hole, wherein a first projection of the second interlocking plate of the set of interlocking plates engages the first hole and a second projection of the second interlocking plate of the set of interlocking plates engages the second hole.

14. The method of claim 11 wherein the step of providing a set of resilient spacers further comprises providing each resilient spacer of the set of resilient spacers with a hole allowing force rotation about the pivot pin.

15. The method of claim 11 further providing a cross section chosen from the group of circular, rectangular, and oblong for each resilient spacer of the set of resilient spacers with a hole allowing force rotation about the pivot pin.

16. The method of claim 11 further comprising the step of forming each resilient spacer of the set of resilient spacers of a semi-rigid plastic polymer.
