Zero weight articulating access door
View Patent ↗A weightless articulating door mount for a gaming machine is disclosed. The weightless articulating door mount has a four link mechanism and a cam. A biasing mechanism interacts with the weightless articulating door mount through the cam and provides a uniform force counteracting the weight of the door/monitor. With the door/monitor effectively weightless, the door may be opened and will remain in place absent any further disturbance.
1. An articulating mount for an access door, comprising:
a four-link mechanism having a stationary link configured to fixedly couple to a gaming console at two or more mounting points, a door link opposite the stationary link, the door link configured to fixedly couple to a door at two or more mounting points, an upper link rotatably coupled to the stationary link and the door link, and a lower link rotatably coupled to the stationary link and the door link;
a biasing mechanism comprising a torsion spring, the biasing mechanism is coupled to at least one link of the four link mechanism; and
a cam coupled to a link adjacent the at least one link, the cam providing a position dependent interface for the biasing mechanism to bias the orientation of the door link against a known force.
2. The mount of claim 1 , wherein the biasing mechanism is coupled to the stationary link and the cam is coupled to the lower link.
3. The mount of claim 1 , wherein the interaction of the cam and the biasing mechanism causes a constant force opposite the known force.
4. The mount of claim 1 , wherein the door link is coupled to a monitor for the gaming system.
5. The mount of claim 1 , wherein the upper link and lower link are parallel to one another.
6. The mount of claim 1 , wherein the stationary link and the door link are parallel to one another.
7. The mount of claim 1 , wherein the door link is vertical.
8. A gaming console, comprising:
a cabinet enclosing a processor and a non-transitory memory storing instructions for execution of an electronic game of chance;
a door providing access to an interior of the cabinet; and
at least one mount securing the door to the cabinet, the at least one mount comprising:
a four-link mechanism having a stationary link fixedly coupled to the gaming cabinet at two or more mounting points, a door link opposite the stationary link, the door link fixedly coupled to the door at two or more mounting points, an upper link rotatably coupled to the stationary link and the door link, and a lower link rotatably coupled to the stationary link and the door link;
a biasing mechanism comprising a torsion spring, the biasing mechanism is coupled to at least one link of the four link mechanism; and
a cam coupled to a link adjacent the at least one link, the cam providing a position dependent interface for the biasing mechanism to bias the orientation of the door link against a known force.
9. The gaming console of claim 8 , wherein the biasing mechanism is coupled to the stationary link and the cam is coupled to the lower link.
10. The gaming console of claim 8 , wherein the interaction of the cam and the biasing mechanism causes a constant force opposite the known force.
11. The gaming console of claim 8 , wherein the door link is coupled to a monitor for the gaming system.
12. The gaming console of claim 8 , wherein the upper link and lower link are parallel to one another.
13. The gaming console of claim 12 , wherein the stationary link and the door link are parallel to one another.
14. A method of securing a door to a gaming console, the method comprising:
rotatably securing a top link to a stationary link fixedly coupled to the gaming console at two or more mounting points;
rotatably securing a bottom link to a stationary link fixedly coupled to the gaming console at two or more mounting points;
rotatably securing the top link to the door;
rotatably securing the bottom link to the door;
coupling a cam to of the top link, the bottom link, the door, and the gaming console;
securing a torsion spring to the gaming console; and
providing an upward bias to the door through the cam, the cam configured to provide a uniform upward force to the door throughout a working range of the door.
15. The method of claim 14 , further comprising securing a monitor to the door.
16. The method of claim 14 , further comprising coupling an arm to the torsion spring.
