## Abstract

A hinge is provided with two elements pivotally connected together for relative rotational movement about a hinge axis. The hinge has a spring formed of bent wire. The spring is mounted on one of the elements and a mechanism causes it to apply a biassing force between the two elements over at least part of their relative rotational movement. The biassing force is transmitted via a finger on the spring. A spreader is arranged to fit over the finger for engagement with the other element. The spreader extends continuously over the finger and engages substantially the whole of the finger.

## Claims

### Claim 1

A hinge comprising:
a first hinge element and a second hinge element pivotally connected together for relative rotational movement about a hinge axis,
a spring formed of bent wire, and
a mechanism for activating the spring to cause it to apply a spring biassing force between the first hinge element and the second hinge element over at least part of their relative rotational movement, the spring being mounted on the first hinge element and having a spring finger for transmitting said spring biassing force, with said mechanism including a spreader fitting over the spring finger and being in operative engagement with the second hinge element, with the spreader being arranged to extend continuously over and engage substantially the whole of the length of the spring finger, wherein the spreader is of a channel-shaped construction and is arranged to straddle the spring finger.

### Claim 2 (depends on 1)

A hinge as claimed in claim 1 wherein the spreader is designed to fit over the spring finger by means of a snap fit.

### Claim 3 (depends on 1)

A hinge as claimed in claim 1 wherein the spreader is formed with lugs to retain it in position on the spring finger.

### Claim 4 (depends on 1)

A hinge as claimed in claim 1 wherein the spreader is substantially planar where it operatively engages the second hinge element.

### Claim 5 (depends on 1)

A hinge as claimed in claim 1 wherein the operative engagement of the spreader with the second hinge element is in the form of line contact.
