## Abstract

A tilt mechanism for an electronic display. A tilt mechanism including a counterbalancing mechanism having a compression spring assembly. Such tilt mechanism allowing an electronic display to be positioned at a variety of tilt angles. A tilt mechanism including a support that is pivotable with respect to a support surface.

## Claims

### Claim 1

A tilt mechanism for a monitor, comprising:
a support;
a tilt bracket tiltable relative to the support about a tilt axis of rotation across a range of tilt angles; and
a first compression spring having a first spring axis nonparallel with the tilt axis of rotation and positioned between the support and the tilt bracket to provide a spring torque acting against a monitor torque created by a monitor operably coupled to the tilt bracket,
wherein an angle formed between the first spring axis and a display surface of the monitor remains constant across the range of tilt angles.

### Claim 2 (depends on 1)

The tilt mechanism of claim 1, wherein the first compression spring can be configured to move between relatively uncompressed position and relatively compressed position when a compressive force is applied, the uncompressed position and the compressed position being spaced apart by a spring deflection distance along the first spring axis, so that the compression force increases as the spring deflection distance decreases.

### Claim 3 (depends on 1)

The tilt mechanism of claim 1, wherein
the monitor has a monitor weight and is disposed at a first distance from the tilt axis of rotation, the monitor torque increasing proportionally with the increase in first distance, and
the spring axis being positioned at a second distance from the tilt axis of rotation, the spring torque increasing proportionally with the increase in the compression force.

### Claim 4 (depends on 1)

The tilt mechanism of claim 1 wherein the tilt angle is between approximately −15 degrees and approximately 90 degrees.

### Claim 5 (depends on 4)

The tilt mechanism of claim 4, wherein the spring torque is approximately equal to the monitor torque.

### Claim 6 (depends on 1)

The tilt mechanism of claim 1, further comprising a spring holder bracket operatively connected to the tilt bracket, the spring holder bracket configured to provide a restraining support for the first compression spring.

### Claim 7 (depends on 1)

The tilt mechanism of claim 1, further comprising a spring cap positioned adjacent a first end of the first compression spring such that the first compression spring exerts the compression force on the spring cap.

### Claim 8 (depends on 7)

The tilt mechanism of claim 7, further comprising a compression bracket operably coupled to the spring cap, the angular position of the compression bracket remaining stationary with respect to the support, the first compression spring exerting the compression force on the compression bracket via the spring cap.

### Claim 9 (depends on 1)

The tilt mechanism of claim 1, further comprising a second compression spring having a second spring axis parallel to the first spring axis, the second compression spring positioned between the support and the tilt bracket.

### Claim 10 (depends on 1)

The tilt mechanism of claim 1, further comprising a monitor mounting bracket associated with the tilt bracket, the monitor mounting bracket supporting a monitor.

### Claim 11 (depends on 10)

The tilt mechanism of claim 10, wherein the monitor mounting bracket is operatively connected to or integrally formed with the tilt bracket.

### Claim 12 (depends on 1)

The tilt mechanism of claim 1, wherein the support includes
a base,
a riser pivotable about the base, the riser including a distal end and a proximal end,
the distal end of the riser operably connecting to the tilt bracket of the tilt mechanism and the proximal end of the riser including a base pivot.

### Claim 13 (depends on 12)

The tilt mechanism of claim 12, wherein the riser is pivotable with respect to the base pivot over a range of pivoting positions.
