The hinge assembly includes a first bracket coupled to the cabinet, a second bracket coupled to the display, a first link pair extending from the first bracket, and a second link pair extending from the first bracket. A third link pair is coupled to the first link pair, is coupled to the second link pair, and is coupled to the second bracket. A fourth link pair is extending from the second bracket, and is coupled to the second link pair. The link pairs are coupled to each other and to the brackets at pivot points. The hinge assembly is expandable and retractable between a retracted or expanded position, and is configured to swing the display from a lowered to a raised position as the hinge assembly is expanded. ## Claims ### Claim 1 An electronic gaming machine comprising: a cabinet; a display; and a hinge assembly coupled between the cabinet and the display, the hinge assembly comprising: a first bracket coupled to the cabinet; a second bracket coupled to the display; a first link pair coupled to and extending from the first bracket at a first pivot point; a second link pair coupled to and extending from the first bracket at a second pivot point; a third link pair coupled to the first link pair at a third pivot point, coupled to the second link pair at a fourth pivot point, and coupled to the second bracket at a fifth pivot point; and a fourth link pair coupled to and extending from the second bracket at a sixth pivot point, and coupled to the second link pair at a seventh pivot point, wherein the hinge assembly is selectively expandable and retractable between a fully retracted position and a fully expanded position, wherein the hinge assembly is configured to swing the display from a lowered position to a raised position as the hinge assembly is expanded from the fully retracted position to the fully expanded position. ### Claim 2 (depends on 1) The electronic gaming machine in accordance with claim 1, wherein the display is orientable substantially vertically when the hinge assembly is in the fully retracted position, and is orientable substantially horizontally when the hinge assembly is in the fully expanded position. ### Claim 3 (depends on 1) The electronic gaming machine in accordance with claim 1, wherein the hinge assembly is configured to move the display in a parabolic range of motion between the fully retracted position and the fully expanded position. ### Claim 4 (depends on 1) The electronic gaming machine in accordance with claim 1, wherein the second link pair comprises a first section, a second section, and a third section, the first section oriented obtusely relative to the second section, and the second section oriented obtusely relative to the third section. ### Claim 5 (depends on 4) The electronic gaming machine in accordance with claim 4, wherein the fourth pivot point is defined between the second section and the third section of the second link pair. ### Claim 6 (depends on 1) The electronic gaming machine in accordance with claim 1, wherein the third link pair comprises a first section and a second section oriented obtusely relative to the first section. ### Claim 7 (depends on 1) The electronic gaming machine in accordance with claim 1, wherein the hinge assembly has a range of motion configured to progressively increase a distance between the first bracket and the second bracket as the hinge assembly is expanded from the fully retracted position to the fully expanded position. ### Claim 8 (depends on 1) The electronic gaming machine in accordance with claim 1 further comprising at least one gas spring coupled between the cabinet and the display. ### Claim 9 A hinge assembly comprising: a first bracket comprising a first mounting surface; a second bracket comprising a second mounting surface; a first link pair coupled to and extending from the first bracket at a first pivot point; a second link pair coupled to and extending from the first bracket at a second pivot point; a third link pair coupled to the first link pair at a third pivot point, coupled to the second link pair at a fourth pivot point, and coupled to the second bracket at a fifth pivot point; and a fourth link pair coupled to and extending from the second bracket at a sixth pivot point, and coupled to the second link pair at a seventh pivot point, wherein the hinge assembly is selectively expandable and retractable between a fully retracted position and a fully expanded position, wherein the first mounting surface and the second mounting surface are substantially perpendicular to each other when the hinge assembly is in the fully retracted position, and are substantially parallel with each other when the hinge assembly is in the fully expanded position. ### Claim 10 (depends on 9) The hinge assembly in accordance with claim 9, wherein the hinge assembly is configured to move in a parabolic range of motion between the fully retracted position and the fully expanded position. ### Claim 11 (depends on 9) The hinge assembly in accordance with claim 9, wherein the second link pair comprises a first section, a second section, and a third section, the first section oriented obtusely relative to the second section, and the second section oriented obtusely relative to the third section, and wherein the third link pair comprises a first section and a second section oriented obtusely relative to the first section. ### Claim 12 (depends on 11) The hinge assembly in accordance with claim 11, wherein the fourth pivot point is defined between the second section and the third section of the second link pair, and between the first section and the second section of the third link pair. ### Claim 13 (depends on 11) The hinge assembly in accordance with claim 11, wherein the first section is coupled to the first bracket at the second pivot point, and the third section is coupled to the fourth link pair at the seventh pivot point. ### Claim 14 An electronic gaming machine comprising: a cabinet; a display; and a hinge assembly coupled between the cabinet and the display, the hinge assembly comprising: a first bracket coupled to the cabinet; a second bracket coupled to the display; a first link pair coupled to and extending from the first bracket at a first pivot point; a second link pair coupled to and extending from the first bracket at a second pivot point; a third link pair coupled to the first link pair at a third pivot point, coupled to the second link pair at a fourth pivot point, and coupled to the second bracket at a fifth pivot point; and a fourth link pair coupled to and extending from the second bracket at a sixth pivot point, and coupled to the second link pair at a seventh pivot point, wherein the hinge assembly is selectively expandable and retractable between a fully retracted position and a fully expanded position, wherein the hinge assembly is configured to swing the display through a range of motion having an apex positioned exterior of the cabinet. ### Claim 15 (depends on 14) The electronic gaming machine in accordance with claim 14, wherein the hinge assembly is configured to move the display in a parabolic range of motion through the apex between the fully retracted position and the fully expanded position. ### Claim 16 (depends on 14) The electronic gaming machine in accordance with claim 14, wherein the range of motion is defined by a substantially linear component and an arcuate component positioned closer to the apex than the substantially linear component. ### Claim 17 (depends on 14) The electronic gaming machine in accordance with claim 14, wherein the second link pair comprises a first section, a second section, and a third section, the first section oriented obtusely relative to the second section, and the second section oriented obtusely relative to the third section, and wherein the third link pair comprises a first section and a second section oriented obtusely relative to the first section. ### Claim 18 (depends on 17) The electronic gaming machine in accordance with claim 17, wherein the fourth pivot point is defined between the second section and the third section of the second link pair, and between the first section and the second section of the third link pair. ### Claim 19 (depends on 17) The electronic gaming machine in accordance with claim 17, wherein the first section is coupled to the first bracket at the second pivot point, and the third section is coupled to the fourth link pair at the seventh pivot point. ### Claim 20 (depends on 14) The electronic gaming machine in accordance with claim 14, wherein the hinge assembly has a range of motion configured to progressively increase a distance between the first bracket and the second bracket as the hinge assembly is expanded from the fully retracted position to the fully expanded position.
