Abstract

A display hinge system includes a latching hinge and a friction hinge. The latching hinge includes a latching hinge moulding with first and second toothed locking plates, and a latch lever mechanism configured to move the first toothed locking plate toward and away from the second toothed locking plate. In one configuration, the first toothed locking plate does not engage the second toothed locking plate and the display hinge system is free to rotate. In another configuration, the first toothed locking plate engages the second toothed locking plate and prevents rotation of the display hinge system. The friction hinge includes a friction hinge moulding, a friction hinge cap, and a torque hinge. The torque hinge has a first part mechanically coupled to the friction hinge moulding and a second part mechanically coupled to the friction hinge cap. The friction hinge is configured to resist rotation of the display hinge system.

First claim

What is claimed is:

1 . A display hinge system comprising a latching hinge and a friction hinge, the display hinge system configured to rotatably couple a display panel to a control panel, wherein:
the latching hinge comprises:
a latching hinge moulding fixedly coupled to the control panel;
a first toothed locking plate translatably and non-rotatably mounted to the latching hinge moulding;
a second toothed locking plate fixedly coupled to the display panel; and
a latch lever mechanism mechanically coupled to the first toothed locking plate and configured to move the first toothed locking plate toward and away from the second toothed locking plate, wherein:
in a first configuration of the latch lever mechanism, teeth of the first toothed locking plate do not engage the teeth of the second toothed locking plate and the display panel is free to rotate relative to the control panel; and
in a second configuration of the latch lever mechanism, the teeth of the first toothed locking plate engage the teeth of the second toothed locking plate and prevent the display panel from rotating relative to the control panel; and

the friction hinge comprises:
a friction hinge moulding fixedly coupled to the control panel;
a friction hinge cap fixedly coupled to the display panel; and
a torque hinge having a first part and a second part, wherein the first part is mechanically coupled to the friction hinge moulding and the second part is mechanically coupled to the friction hinge cap,
wherein the friction hinge is configured to resist rotation of the display panel relative to the control panel.

2 . The display hinge system of claim 1 , wherein:
the torque hinge is configured as a cylinder, the first part comprises a first end of the cylinder, and the second part comprises a second, opposite end of the cylinder.

3 . The display hinge system of claim 2 , wherein the first part is prevented from rotating relative to the friction hinge moulding by a first radial extension from the first part, wherein the first radial extension is constrained within a recess in the friction hinge moulding; and
the second part is prevented from rotating relative to the friction hinge cap by a second radial extension from the second part, wherein the second radial extension is constrained within a recess in the friction hinge cap.

4 . The display hinge system of claim 1 , wherein a separation spring is positioned between the first and second toothed locking plates and configured to bias the first and second toothed locking plates apart.

5 . The display hinge system of claim 1 , wherein the latch lever mechanism comprises an override spring coupled to the latch lever mechanism and the first toothed locking plate and configured to bias the first toothed locking plate toward the second toothed locking plate.

6 . The display hinge system of claim 5 , wherein one or both of the first and second toothed locking plates comprise teeth configured to convert a rotational torque, applied to rotate the first and second toothed locking plates relative to each other, into an axial force in a direction that compresses the override spring and causes the first toothed locking plate to move away from the second toothed locking plate.

7 . The display hinge system of claim 1 , wherein the latch lever mechanism comprises:
a shaft configured to move the first toothed locking plate toward and away from the second toothed locking plate; a latch lever seat fixedly coupled to the display panel comprising a curved seat surface; and a latch lever, rotatably coupled to the shaft by a hinge pin, the latch lever comprising a curved portion configured to mate with the curved seat surface, wherein the hinge pin is located in a position in the latch lever relative to the curved portion configured to cause the hinge pin to move relative to the latch lever seat coaxially along a long axis of the shaft, thereby moving the first toothed locking plate toward and away from the second toothed locking plate.

8 . The display hinge system of claim 1 , wherein:
the first toothed locking plate comprises a bar; the latching hinge moulding comprises a slot configured to receive the bar; and the bar and the slot are configured to prevent rotation of the first toothed locking plate relative to the latching hinge moulding when the bar is engaged in the slot.

9 . The display hinge system of claim 1 , wherein:
the latching hinge further comprises a pin fixedly coupled to the latching hinge moulding; the first toothed locking plate comprises a clearance aperture configured to receive the pin; and the pin and the clearance aperture are configured to prevent rotation of the first toothed locking plate relative to the latching hinge moulding.

10 . A lighting console comprising a control panel and a display panel, wherein the display panel is rotatably coupled to the control panel by a display hinge system comprising a latching hinge and a friction hinge, wherein:
the latching hinge comprises:
a latching hinge moulding fixedly coupled to the control panel;
a first toothed locking plate translatably and non-rotatably mounted to the latching hinge moulding;
a second toothed locking plate fixedly coupled to the display panel; and
a latch lever mechanism mechanically coupled to the first toothed locking plate and configured to move the first toothed locking plate toward and away from the second toothed locking plate, wherein:
in a first configuration of the latch lever mechanism, teeth of the first toothed locking plate do not engage the teeth of the second toothed locking plate and the display panel is free to rotate relative to the control panel; and
in a second configuration of the latch lever mechanism, the teeth of the first toothed locking plate engage the teeth of the second toothed locking plate and prevent the display panel from rotating relative to the control panel; and

the friction hinge comprises:
a friction hinge moulding fixedly coupled to the control panel;
a friction hinge cap fixedly coupled to the display panel; and
a torque hinge having a first part and a second part, wherein the first part is mechanically coupled to the friction hinge moulding and the second part is mechanically coupled to the friction hinge cap,
wherein the friction hinge is configured to resist rotation of the display panel.

11 . The lighting console of claim 10 , wherein:
the torque hinge is configured as a cylinder, the first part comprises a first end of the cylinder, and the second part comprises a second, opposite end of the cylinder.

12 . The lighting console of claim 11 , wherein the first part is prevented from rotating relative to the friction hinge moulding by a first radial extension from the first part, wherein the first radial extension is constrained within a recess in the friction hinge moulding; and
the second part is prevented from rotating relative to the friction hinge cap by a second radial extension from the second part, wherein the second radial extension is constrained within a recess in the friction hinge cap.

13 . The lighting console of claim 10 , wherein a separation spring is positioned between the first and second toothed locking plates and configured to bias the first and second toothed locking plates apart.

14 . The lighting console of claim 10 , wherein the latch lever mechanism comprises an override spring coupled to the latch lever mechanism and the first toothed locking plate and configured to bias the first toothed locking plate toward the second toothed locking plate.

15 . The lighting console of cla
