Adjustable Height Table Chassis
This project was designed to fulfill a somewhat niche purpose. Most people don’t have the need to use a dining table for multiple hours at a time, where having it be of adjustable height so that it can be used while standing is a desirable feature. This was meant for people that play board games regularly at a table, or for other people who use the dining table as a work area. The mechanism that the table works by is using an acme threaded rod as a lead screw, with two timing belt pulleys, which had been machined to incorporate an acme threaded hex bolt which was then welded into the pulley, driving the shafts up and down which cause the raising and lowering of the table. Due to the lead angle on the acme shafts they are self-locking which means that there does not need to be a secondary holding mechanism to prevent the table from falling once it is raised. It was designed to hold a 600 pound distributed load across the surface of the chassis with a designated factor of safety of 1.3, which through nondestructive testing the chassis was able to support.
