An electronic gaming machine that includes a cabinet, a display, and a hinge assembly coupled therebetween. The hinge assembly includes a first bracket coupled to the cabinet, a second bracket coupled to the display, and at least four pairs of interdigitated members extending between the first bracket and the second bracket. The hinge assembly is selectively expandable and retractable between a retracted position and an expanded position, and 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 retracted position to the expanded position.

A hinge assembly for securing a door on a gaming machine cabinet includes a first flange coupled to the door, a second flange coupled to the cabinet, a first link pair coupled to and extending from the first flange at a first pivot joint, a second link pair coupled to and extending from the first flange at a second pivot joint, a third link pair coupled to the first link pair at a third pivot joint, wherein the third link pair is further coupled to the second flange at a fourth pivot joint, and wherein the third link pair is further coupled to the second link pair at a fifth pivot joint, and a fourth link pair coupled to the second flange at a sixth pivot joint, wherein the fourth link pair is further coupled to the second link pair at a seventh pivot joint.

A door hinge for a laboratory instrument door, the door hinge comprising a hollow body with a first longitudinal axis and a curved side wall comprising a track. At least a part of the track is inclined relative to the first longitudinal axis. The door hinge further comprises a linear guiding element with a second longitudinal axis parallel to the first longitudinal axis. At least a part of the linear guiding element is arranged in the hollow. The linear guiding element and the hollow body are rotatable against each other. The door hinge further comprises a body comprising a protruding pin. The body is movably attached to the linear guiding element so that the body is movable in two opposite directions along the second longitudinal axis and the protruding pin is movable on the track.

To provide an opening and closing device for opening and closing body having a rotation torque controlling module and a torque peak adjusting module, solution was sought by an opened and closed body and the opening and closing body which comprises an attaching part, an opening and closing part rotatably attached to the attaching part via a hinge shaft, a rotation torque controlling module for controlling a rotation torque of the opening and closing part, a torque peak adjusting module for adjusting a torque peak of the opening and closing part at the time of its opening and closing movement.

A closure apparatus for openings for access to industrial machines includes a door which can move, by virtue of the action of a respective actuator which includes a motorized shaft which supports at least two mutually opposite pulleys for winding flexible elements connected to respective substantially upper and external portions of the door. The actuator includes substantially at an intermediate section of the shaft, at least one third idle pulley for winding at least one third flexible element connected to a substantially upper and central portion of the door. The third pulley is provided with at least one position sensor for detecting an unrolling of the third flexible element.

A hinge, wherein, inter alia, intrusion of foreign matter in a contacting portion of a slide member and a cam member and resulting adhesion of an oil provided in the cam member to the foreign matter is reliability prevented from the closed state to the open state of a second wing member. The hinge is provided with an oil fence disposed on the outside close to the contacting portion of the cam member and slide member, the oil fence preventing, from the closed slate to the open state of the second wing member, foreign matter front intruding into the contacting portion of the slide member and cant member from the outside of the slide member and cant member.

An electronic gaming machine that includes a cabinet, a display, and a hinge assembly coupled therebetween. The hinge assembly includes a first bracket coupled to the cabinet, a second bracket coupled to the display, and at least four pairs of interdigitated members extending between the first bracket and the second bracket. The hinge assembly is selectively expandable and retractable between a retracted position and an expanded position, and 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 retracted position to the expanded position.

According to one aspect of the invention, an assembly is configured to counterbalance components movable relative to one another, the assembly including a mounting bracket configured to be coupled to one of the components; a follower arm pivotally coupled to a follower arm mounting point on the mounting bracket; a follower coupled to a follower mounting point on the follower arm; means for exerting force between a force exerting means mounting point on the mounting bracket and a force exerting means mounting point on the follower arm; and a cam configured to be coupled to another one of the components in such a way that the follower contacts a cam profile of the cam.

An electronic gaming machine that includes a cabinet, a display, and a hinge assembly coupled therebetween. 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.
